Memarzadeh, S., S. B. Lee, J. S. Berek et R. Farias-Eisner. « CA125 levels are a weak predictor of optimal cytoreductive surgery in patients with advanced epithelial ovarian cancer ». International Journal of Gynecologic Cancer 13, no 2 (février 2003) : 120–24. http://dx.doi.org/10.1136/ijgc-00009577-200303000-00003.
Texte intégralRésumé :
The utility of preoperative CA125 to predict optimal primary tumor cytoreduction in patients with advanced (stages IIIC and IV) epithelial ovarian cancer is controversial. In this paper, we retrospectively review patients with stage IIIC and IV epithelial ovarian cancer who underwent primary cytoreductive surgery from 1989 to 2001. Ninety-nine patients were identified and included in the analysis. All patients had preoperative CA125 levels measured. Operative and pathology reports were reviewed. Optimal cytoreduction was defined as largest volume of residual disease < 1 cm in maximal dimension. Mean values were compared with t-test on a log scale when needed. The optimal cut-point for discriminating between those with vs. without optimal cytoreduction was determined using the receiver operator curve (ROC) method. Optimal cytoreduction was achieved in 73% of patients. Among patients with optimal cytoreductive status the mean CA125 level was 569, while among patients with suboptimal cytoreduction the mean CA125 level was 1520 (P < 0.007). A CA125 level of 912 was identified as the optimal cut-point to distinguish the two groups. Using this CA125 level, the sensitivity of this test in predicting optimal cytoreduction was 58% and the specificity was 54%. The positive predictive value of CA125 for optimal cytoreduction was 78% and the negative predictive value was 31%. We conclude that CA125 level is a weak positive and negative predictor of optimal cytoreductive surgery in patients with advanced epithelial ovarian cancer. The CA125 level should not be used as a primary predictor of the outcome of cytoreductive surgery and should be viewed in the context of all other preoperative features.

Texte intégralRésumé :
Background. Diaphragmatic peritoneal metastasis by advanced epithelial ovarian cancer is a very common holdback precluding optimal cytoreduction. The aim of this study was to determine the rate of diaphragmatic peritonectomy during optimal cytoreductive surgery and its role in postoperative morbidity and survival in patients with advanced ovarian cancer. Materials and methods. 100 consecutive patients with advanced epithelial ovarian cancer underwent cytoreductive surgery and were followed up prospectively (January 2009 – March 2014). Characteristics of surgery, rate of diaphragmatic peritonectomy and post operative complications were assessed. The Kaplan-Meier method was used for survival analysis. Results. The median age of the entire cohort at the time of primary cytoreduction was 58.5 years (23–83). Optimal cytoreduction was achieved in 73 cases out of 100 patients. From 73 patients in 30 cases (41.1%) upper abdominal procedures, specifically diaphragmatic peritonectomy, was performed to achieve the main goal of cytoreduction – no visible or palbable disease at the end of cytoreduction. Non-optimal cytoreduction was achieved in 27 cases. According to the Clavien-Dindo complication grading system grade I and grade II complications occurred more often in patients that underwent diaphragmatic surgery. The median overall survival from the time of diagnosis to the last follow-up or death was 28 months (range 0–63 months). The factors associated with the longest survival after primary cytoreductive surgery were the disease free interval from the primary cytoreduction of more than 19 months (n = 51) versus less than 19 months (n = 49) (95% confidence interval, 51.7–59.5; P = 0.013) and no visible or palpable residual disease at the end of cytoreduction (n = 73) versus visible or palpable residual disease (n = 27) (95% confidence interval, 52.7–61.2; P = 0.03). Conclusions. Based on our prospective analysis of advanced ovarian cancer patients, diaphragmatic peritonectomy is feasible and safe, ensures better rates of optimal cytoreduction and should not be an obstacle towards better survival.

Texte intégralRésumé :
Purpose: Several studies have shown the benefit of cytoreductive surgery in advanced disease, that is why the residual tumor has prognostic value. Our primary objective was to determine the frequency of involvement of the upper abdomen, defined as the extension of the disease above the transverse colon (diaphragm, spleen, gallbladder, stomach, hepatic parenchyma, hepatic capsule, minor omentum, hepatic ilium, pancreas). Our secondary objective was to analyze the possibilities of complete cytoreduction in these patients, their complications and results. Materials and methods: We retrospectively include patients undergoing primary and secondary cytoreduction due to ovarian carcinoma between January 2008 and December 2012, in the gynecology department of the German Hospital. Results: One hundred and thirty nine patients with ovarian carcinoma were analyzed. An average age of 60 years (28-90). 91 of them with attempted primary cytoreduction and 48 secondary cytoreduction. In the group of primary cytoreductions we excluded 17 patients that were stages I and II, 20 (22%) of the 74 stages III-IV had upper abdomen involvement, 17 stages III and 3 stages IV. Those stage IV patients were only limited to hepatic intraparenchymal involvement. Of the 48 secondary cytoreductions, 21 (43%) presented upper abdominal involvement. Including both groups we have 30% of upper abdomen compromise. Complete or optimal cytoreduction was achieved in 56% of them. Conclusion: The exploration of the superior abdomen in ovarian cancer surgery is key, and the approach of this patients by a team of properly trained gynecologists is mandatory if we want to obtain better complete cytoreduction rates.

Texte intégralRésumé :
Pseudomixoma peritonei is a rare type of peritoneal carcinomatosis accompanied by accumulation of mucus and high recurrence rate and in some cases complicated with intestinal obstruction. In the last 10–15 years, there has been observed a significant improvement in overall survival of patients with recurrent pseudomyxoma, who underwent cytoreductive surgery in combination with intraperitoneal chemotherapy. However, the frequency of recurrences of peritoneal pseudomyxoma after optimal cytoreduction can reach 80–90 % in the first 2 years.The purpose of the study was to analyze the results of combined therapy (cytoreductive surgery and hypothermic intraperitoneal chemoperfusion) in patients with recurrent pseudomyxoma peritonei, who previously underwent cytoreductive surgery.Material and Methods. The study included 43 patients previously undergoing cytoreductive surgery for pseudomyxoma peritonei in the Thoracic Oncology Department of the N.N. Blokhin National Medical Research Center of Oncology.Results. Re-operations were performed in 11 of the 43 patients with recurrent pseudomixoma peritonei after previously performed cytoreductive surgery. Repeated intraperitoneal chemoperfusion with hyperthermia was performed in 6 patients. Of the 11 reoperated patients, 7 had a complete cytoreduction (CC-0), recurrence was detected within 22 to 47 months; 2 patients had CC-1 and recurrence was observed within 12 and 15 months. Optimal cytoreduction (CC0-1) was achieved in 7 of the 11 patients. The maximum follow-up period was 44 months. Recurrence was noted in 9 patients, while the majority of patients had a satisfactory quality of life. Two patients showed signs of partial intestinal obstruction. None of the patients died during the follow-up period. In two patients with optimal (CC-0) cytoreduction, there were no signs of disease progression 9 and 15 months after re-surgery. One-year disease-free survival rate was 51 %.Conclusion. Repeated surgeries for recurrent pseudomyxoma present a great challenge for surgeons due to the difficulty in achieving optimal cytoreduction. Optimal cytoreduction in initial surgery should be considered as the main condition for repeated surgery. Moreover, additional criterion for a favorable prognosis is the time to progression of disease.

ObjectiveThe aim of this study was to determine the effect of salvage cytoreductive surgery (SCS) on overall survival (OS) among patients with recurrent endometrial cancer and if there is any predictor for residual tumor status.MethodsBetween January 1993 and May 2013, data of 34 patients who had SCS for recurrent endometrial cancer were retrospectively analyzed. Overall survival was determined from SCS to last follow-up.ResultsThe surgical procedure was local excision without laparotomy in 12 patients, and optimal cytoreduction (no visible disease) was achieved in 24 of 34 patients. There were no perioperative deaths. None of the factors was associated with achievement of optimal cytoreduction. Five-year OS rates were 37% and 27% for the entire cohort and for the laparotomy group, respectively. For the entire cohort, disease-free interval (from initial surgery to recurrence), adjuvant therapy after initial surgery, CA-125 level at recurrence, multiplicity of recurrence, surgical procedure, and optimal cytoreduction and for the laparotomy group adjuvant treatment and optimal cytoreduction were associated with OS. In the laparotomy group, OS rates were 53 and 9 months in the patients who did and did not have optimal SCS, respectively.ConclusionsSignificant survival benefit can be achieved with optimal resection. Prospective studies should be designed to define optimal cytoreduction and to determine the predictors of optimal cytoreduction achievement.

Texte intégralRésumé :
Retrospective evidence supports the value of optimal cytoreductive surgery in the initial therapy of patients with advanced ovarian cancer. Specialized procedures, including radical pelvic surgery, bowel resection, and diaphragm resections, are frequently necessary to accomplish optimal cytoreduction. Cytoreduction and total gross tumor removal are possible more frequently with new surgical instruments such as the Cavitron ultrasonic surgical aspirator and argon beam laser. Pelvic and periaortic lymph node resection is an important aspect of cytoreductive surgery, and systematic removal of grossly uninvolved lymph nodes may improve survival. Secondary cytoreductive surgery appears to benefit a select group of patients.

Objective: To evaluate the agreement between multiple detector CT (MDCT) and laparoscopy in the preoperative categorization of peritoneal carcinomatosis, and to determine the impact of this categorization on the prediction of cytoreduction status. Methods: This prospective study included 80 consecutive females with primary ovarian cancer eligible for cytoreductive surgery (CRS). MDCT and diagnostic laparoscopy were performed prior to surgery for assessment of peritoneal carcinomatosis extent. Based on PCI (peritoneal cancer index) score, carcinomatosis was categorized into three groups. Categorization agreement between CT and laparoscopy was assessed and compared with the intraoperative-histopathologically proven PCI. Impact of PCI categorization on cytoreduction status was also evaluated. Results: The overall agreement between CT and laparoscopy in preoperative peritoneal carcinomatosis categorization was good (K =0.71-0.79) in low category group and excellent in both moderate and large group (interclass correlation coeeficient = 0.89–0.91). (p<0.01) Optimal cytoreduction was achieved in 62/80 (77.5%) patients, PCI < 20 was detected in 48/62 (77.4%), pre-operative PCI < 20 correctly predicted optimal cytoreductive surgery (OCS) in 40/48 (83.3%) cases. Suboptimal cytoreduction was performed in 18/80 (22.5%) patients. PCI > 20 was detected in (10/18) 55.6%, preoperative CT and laparoscopy PCI > 20 correctly predicted SCS in 8/10 (80%) cases. The area under receiver operating characteristic curve showed that PCI cut-off <20 was the best predictor of OCS with an accuracy 85%, sensitivity 97%, specificity 40%, negative predictive value 76%, and positive predictive value 93%. Conclusion: Both laparoscopy and CT are equally effective in pre-operative peritoneal carcinomatosis categorization. PCI < 20 is accurate in the prediction of optimal cytoreduction. More than half of patients with suboptimal cytoreduction had PCI > 20 and interval debulking surgery can be recommended. Advances in knowledge: Both laparoscopy and CT are equally effective in pre-operative peritoneal carcinomatosis categorization. PCI < 20 is accurate in the prediction of optimal cytoreduction. More than half of patients with suboptimal cytoreduction had PCI > 20 and interval debulking surgery can be recommended.

Texte intégralRésumé :
Advanced high-grade serous (HGSC) ovarian cancer is treated with either primary surgery followed by chemotherapy or neoadjuvant chemotherapy followed by interval surgery. The decision to proceed with surgery primarily or after chemotherapy is based on a surgeon’s clinical assessment and prediction of an optimal outcome. Optimal and complete cytoreductive surgery are correlated with improved overall survival. This clinical assessment results in an optimal surgery approximately 70% of the time. We hypothesize that this prediction can be improved by using biological tumor data to predict optimal cytoreduction. With access to a large biobank of ovarian cancer tumors, we obtained genomic data on 83 patients encompassing gene expression, exon expression, long non-coding RNA, micro RNA, single nucleotide variants, copy number variation, DNA methylation, and fusion transcripts. We then used statistical learning methods (lasso regression) to integrate these data with pre-operative clinical information to create predictive models to discriminate which patient would have an optimal or complete cytoreductive outcome. These models were then validated within The Cancer Genome Atlas (TCGA) HGSC database and using machine learning methods (TensorFlow). Of the 124 models created and validated for optimal cytoreduction, 21 performed at least equal to, if not better than, our historical clinical rate of optimal debulking in advanced-stage HGSC as a control. Of the 89 models created to predict complete cytoreduction, 37 have the potential to outperform clinical decision-making. Prospective validation of these models could result in improving our ability to objectively predict which patients will undergo optimal cytoreduction and, therefore, improve our ovarian cancer outcomes.

ObjectivesCytoreductive surgery is the cornerstone of ovarian cancer (OVCA) treatment. Detractors of initial maximal surgical effort argue that aggressive tumor biology will dictate survival, not the surgical effort. We investigated the role of biology in achieving optimal cytoreduction in serous OVCA using microarray gene expression analysis.MethodsFor the initial model, we used a gene expression signature from a microarray expression analysis of 124 women with serous OVCA, defining optimal cytoreduction as removal of all disease greater than 1 cm (with 64 women having optimal and 60 suboptimal cytoreduction). We then applied this model to 2 independent data sets: the Australian Ovarian Cancer Study (AOCS; 190 samples) and The Cancer Genome Atlas (TCGA; 468 samples). We performed a second analysis, defining optimal cytoreduction as removal of all disease to microscopic residual, using data from AOCS to create the gene signature and validating results in TCGA data set.ResultsOf the 12,718 genes included in the initial analysis, 58 predicted accuracy of cytoreductive surgery 69% of the time (P= 0.005). The performance of this classifier, measured by the area under the receiver operating characteristic curve, was 73%. When applied to TCGA and AOCS, accuracy was 56% (P= 0.16) and 62% (P= 0.01), respectively, with performance at 57% and 65%, respectively. In the second analysis, 220 genes predicted accuracy of cytoreductive surgery in the AOCS set 74% of the time, with performance of 73%. When these results were validated in TCGA set, accuracy was 57% (P= 0.31) and performance was at 62%.ConclusionGene expression data, used as a proxy of tumor biology, do not predict accurately nor consistently the ability to perform optimal cytoreductive surgery. Other factors, including surgical effort, may also explain part of the model. Additional studies integrating more biological and clinical data may improve the prediction model.

Texte intégralRésumé :
IntroductionWith the rapid uptake of robotic surgery in surgical oncology, its use in the treatment of epithelial ovarian cancers is being evaluated. Complete cytoreduction represents the goal of surgery either at primary cytoreduction or after neoadjuvant chemotherapy in the setting of interval cytoreduction. In selected patients, the extent of disease would enable minimally invasive surgery. The objective of this study was to evaluate the impact of introducing robotic surgery for interval cytoreduction of selected patients with stage III–IV ovarian cancer.MethodsAll patients who underwent surgery from November 2008 to 2014 (concurrent time period when robotic and open surgery were used simultaneously) after receiving neoadjuvant chemotherapy for advanced ovarian cancer (stage III–IV) were compared with all consecutive patients who underwent cytoreductive surgery by laparotomy after neoadjuvant chemotherapy between January 2006 and November 2008. Inclusion criteria included an interval cytoreductive surgery by laparotomy or robotic assistance for stage III–IV non-mucinous epithelial ovarian, fallopian tube, or primary peritoneal cancer. Exclusion criteria included patients treated concurrently for a non-gynecologic cancer, as well as secondary cytoreductive surgeries and diagnostic surgeries without an attempt at tumor reduction. Overall survival, progression-free survival, and peri-operative outcomes were compared for the entire patient cohort with those with advanced ovarian cancer who received neoadjuvant chemotherapy immediately before and after the introduction of robotic surgery.ResultsA total of 91 patients were selected to undergo interval cytoreduction either via robotic surgery (n=57) or laparotomy (n=34) after the administration of neoadjuvant chemotherapy. The median age of the cohort was 65 years (range 24–88), 78% had stage III disease, and the median follow-up time was 37 months (5.6–91.4 months). The median survival was 42.8±3.1 months in the period where both robotic surgery and laparotomy were offered compared with 37.9±9.8 months in the time period preceding when only laparotomy was performed (p=0.6). All patients selected to undergo interval robotic cytoreduction following neoadjuvant chemotherapy had a reduction of cancer antigen 125 by at least 80%, resolution of ascites, and CT findings suggesting the potential to achieve optimal interval cytoreduction. All these patients achieved optimal cytoreduction with <1 cm residual disease, including 82% with no residual disease. The median blood loss was 100 mL (mean 135 mL, range 10–1250 mL), and the median hospital stay was 1 day.ConclusionRobotic interval cytoreductive surgery is feasible in well-selected patients. Future studies should aim to define ideal patients for minimally invasive cytoreductive surgery.

Objective. The objective of the present study was to determinate the impact of maximal cytoreductive surgery on progression free survival, overall survival rates and morbidity, in patients with advanced epithelial ovarian or fallopian tube cancer (stage IIIC-IV) treated in a referral cancer center.
Methods. After obtaining Institutional Review Board approval, we reviewed all medical records of patients with stage IIIC–IV epithelial ovarian cancer who were managed at our institution between January 2001 and December 2008. Individual records were reviewed and the following information collected: age at surgery, date of surgery, American Society of Anestesiology (ASA) class, primary site of disease, presence of peritoneal carcinomatosis, histologic type and tumor grade, pre-operative serum CA-125 level, location and size of the largest tumor mass, the initial ascites volume (if present), all surgical procedures performed, size of residual disease after surgery. The Kaplan–Meier method was used to estimate survival curves. Cox proportional hazards regression was performed to identify independent prognostic variables for overall survival by univariate and multivariate analysis.
Results. A total of 269 patients with advanced epithelial ovarian cancer were referred to our institution between January 2001 and December 2008, and of them 240 consecutive patients met inclusion criteria for the study. The median age was 58 years (range 22 to 77 years). After a median follow up of 29.8 months, the overall median survival (OS) and progression free survival (PFS) were 61.1 and 20.4 months respectively. On univariate analysis, factors significantly associated with decreased survival included: age grater than median (>60 years), presence of ascites >1000 cc, diffuse peritoneal carcinomatosis, omentum as anatomical location of the largest tumor mass, positive lymph-nodes and diameter of residual disease. On multivariate analysis confirmed the independent association of age grater than 60 years and residual disease > 5 mm with worse survival.
Conclusion. Our study seems to demonstrate that a more extensive surgical approach is associated with improved survival in patients with stages IIIC-IV epithelial ovarian cancer. Age grater than 60 years and residual tumor grater than 5 mm were independently associated with a worse prognosis.

Texte intégralRésumé :
The ovarian cancer, also known as “silent killer”, has remained the most lethal gynaecological malignancy. The single independent risk factor linked with improved survival is maximum cytoreductive effort resulting in no macroscopic residual disease. This could be gained through ultra-radical surgery which demands tackling significant tumour burden in pelvis, lower and upper abdomen which usually constitutes bowel resection, liver mobilisation, ancillary cholecystectomy, extensive peritonectomy, diaphragmatic resection, splenectomy, resection of enlarged pelvic, paraaortic, and rarely cardio-phrenic lymph nodes in order to achieve optimal debulking. The above can be achieved through a holistic approach to patient’s care, meticulous patient selection, and full engagement of the family. The decision needs to be carefully balanced after obtaining an informed consent, and an appreciation of the impact of such surgery on the quality of life against the survival benefit. This chapter will describe the complexity and surgical challenges in the management of advanced ovarian cancer.

Background: Debate continues whether primary surgery or neo-adjuvant chemotherapy (NACT) or primary debulking surgery (PDS) should be offered in advanced epithelial ovarian cancer as frontline therapy. Since 2015, there has been a paradigm shift at Tata Medical center, whereas increasing number of patients are being offered PDS and a quality improvement programme was initiated. Recently, ESGO in October 2015 has published a document indicating 10 quality indicators for cytoreductive surgery in advanced ovarian cancer surgery. Aim: We compared our performance against all 10 quality indicators. Results: Primary cytoreduction rate has increased from 20% in 2012 to >70% at the end of 2015. Optimal cytoreduction rates were obtained in 90% cases and recently complete (CCO/CC1) cytoreduction rates are being achieved in >80% cases. All 10 quality indicators were achieved successfully including prospective documentation of morbidity and surgical findings in all cases. Morbidity figures are showing a downwards trend after the initial learning curve. Conclusions: Implementation of a quality improvement programme is the key to overcome the barriers of implementing a cytoreductive program in advanced ovarian cancer. However, standards similar to developed countries can be achieved through a dedicated team effort.

Introduction: Surgery plays an important role in the management of advanced stage ovarian cancer and is complex involving surgical procedures including peritonectomy, splenectomy, diaphragmatic stripping, retroperitoneal lymph node dissection and bowel resection including resection of recto-sigmoid. Objective: To assess the safety and efficacy of the patients undergoing modified posterior pelvic exenteration and rectosigmoid anastomosis achieving in optimal cytoreduction. Methods: Between June 2011 and June 2014 a total of 100 patients underwent surgical cytoreduction for advanced epithelial ovarian cancer of which 20 patients had undergone modified posterior pelvic exenteration with rectosigmoid anastomosis. The present study includes a retrospective analysis of these 20 patients. Rectosigmoid anastomosis was done using circular stapler in these patients. All patients had a PS score of 1 or 2. Results: The median age of patients was 50 years. The optimal status of no macroscopic residual disease was achieved in all patients. Modified posterior pelvic exenteration with rectosigmoid anastomosis was carried out to achieve optimal status of surgical cytoreduction in 20 patients out of which fifteen patients had primary surgical cytoreduction, three patients had interval surgical cytoreduction surgery after receiving three cycles of neoadjuvant chemotherapy with paclitaxel & carboplatin while two patients had this procedure as a part of secondary surgical cytoreduction. The most common histology was papillary serous carcinoma. Average blood loss was 500 ml. Mean operative time was 6 hours. There were no intra operative complications. Bowel movements returned to normal in 3 to 5 days. The median length of hospital stay was 7 days. The median time to start postoperative chemotherapy was 32 days. There was no major morbidity and mortality. Conclusion: Modified posterior pelvic exenteration with rectosigmoid anastomosis should be performed when indicated as a part of cytoreduction. In our experience this is a safe and effective procedure to achieve optimal status in advanced ovarian cancer.

Purpose: Neoadjuvant chemotherapy followed by interval debulking surgery (IDS) is an alternative treatment option, compared to the current standard of care primary debulking surgery for treating advanced epithelial ovarian cancer (EOC). We present our institute experience of neoadjuvant chemotherapy strategy in the management of EOC which is one of the largest single institute experience. Methods: This is a retrospective analysis of patients with epithelial ovarian cancer who were treated in our institute between 2000 and 2006. Patient with advanced disease by clinical and imaging were treated with 3 cycles ofneoadjuvant chemotherapy and then taken up for interval debulking surgery (IDS) who had static or partial or complete response to chemotherapy. The remaining chemotherapy is delivered after the surgery. Patient who had limited disease had primary debulking surgery and then adjuvant chemotherapy according to institute protocol. Outcomes in terms of disease free and overall survival were analysed. Results: This retrospective analysis included 59 patients with limited disease who had primary debulking surgeryand 283 patients with advanced disease who recievedneoadjuvant chemotherapy. The median age was 50 years and majority are in the 50-59 years age group. Age more than 60 years represent 14.5%. Postmenopausal women were 55.3% and premenopausal women were 44.7 %. Multiparity is higher 70.2% than the uniparity 16.4% ornulliparity 11.7%. Abdomen distension 42% and pain 25% are the most common symptoms. Advanced stage was the most common presentation 71% with stage III-56.1% and stage IV-14.9%. Among the neoadjuvant chemotherapy group 126/283 (44.5%) had optimal cytoreduction, 44/283 (15.5%) had suboptimal cytoreduction and 113/283 (40%) not suitable for IDS. The 5 year disease free and overall survival was 30.8% and 41.5% in the NACT group with advanced disease and 58.5% and 75.8% in the primary cytoreduction group who had limited diseaserespectively. The 5 years overall survival among the IDS group with optimal cytoreduction was 57.1% and 11.7% for the suboptimal cytoreduction group. The 5 years survival was not affected by the number ofneoadjuvant chemotherapycycles delivered before surgery in the IDS group. Patient who received paclitaxol + carboplatin as first line chemotherapy had better survival than carboplatin alone or cyclophosphamide + cisplatin. Conclusion: NACT as an alternative option to primary debulking surgery in operable EOC is still debatable. But for patient with high disease burden where optimal cytoreduction is not possible NACT strategy is a valid option. Recent randomised controlled trials from Europe had shown the noninferiority of neoadjuvant chemotherapy followed by IDS when compared to the primary debulking surgery in operable advanced EOC.

Purpose: Neoadjuvant chemotherapy followed by interval debulking surgery (IDS) is an alternative treatment option, compared to the current standard of care primary debulking surgery for treating advanced epithelial ovarian cancer (EOC). We present our institute experience of neoadjuvant chemotherapy strategy in the management of EOC which is one of the largest single institute experience. Methods: This is a retrospective analysis of patients with epithelial ovarian cancer who were treated in our institute between 2000 and 2006. Patient with advanced disease by clinical and imaging were treated with 3 cycles of neoadjuvant chemotherapy and then taken up for interval debulking surgery (IDS) who had static or partial or complete response to chemotherapy. The remaining chemotherapy is delivered after the surgery. Patient who had limited disease had primary debulking surgery and then adjuvant chemotherapy according to institute protocol. Outcomes in terms of disease free and overall survival were analysed. Results: This retrospective analysis included 59 patients with limited disease who had primary debulking surgery and 283 patients with advanced disease who received neoadjuvant chemotherapy. The median age was 50 years and majority are in the 50-59 years age group. Age more than 60 years represent 14.5%. Postmenopausal women were55.3 % and premenopausal women were 44.7 %. Multiparity is higher 70.2% than the uniparity 16.4% ornulliparity 11.7%. Abdomen distension 42% and pain 25 % are the most common symptoms. Advanced stage was the most common presentation 71% with stage III-56.1% and stage IV-14.9%. Among the neoadjuvant chemotherapy group 126/283(44.5%) had optimal cytoreduction, 44/283 (15.5%) had suboptimal cytoreduction and 113/283 (40%) not suitable for IDS. The 5 year disease free and overall survival was 30.8% and 41.5% in the NACT group with advanced disease and 58.5% and 75.8% in the primary cytoreduction group who had limited diseaserespectively. The 5 years overall survival among the IDS group with optimal cytoreduction was 57.1% and 11.7% for the suboptimal cytoreduction group. The 5 years survival was not affected by the number of neoadjuvant chemotherapy cycles delivered before surgery in the IDS group. Patient who received paclitaxol + carboplatin as first line chemotherapy had better survival than carboplatin alone or cyclophosphamide + cisplatin.

Abstract Introduction Ovarian cancer is the third most common cancer and the second most common cause of death among gynecological cancers in Indian women. Ovarian cancer is heterogeneous, among them, epithelial ovarian cancer (EOC) is the most common. Primary cytoreductive surgery along with six to eight cycles of a combination of platinum and taxanes chemotherapy is the cornerstone of first-line treatment in EOC. This study was done to find clinicopathological factors affecting survival outcomes with first-line therapy in EOC in a real-world setting. Objectives This study was aimed to find factors affecting progression-free survival (PFS) and overall survival (OS) with first-line treatment in EOC. Materials and Methods We conducted a single-center retrospective study. We screened all the patients diagnosed with ovarian cancer from January 2015 till December 2019. We locked data in August 2019. Eligible patients were histologically confirmed EOC who underwent primary cytoreduction or received more than or equal to two cycles of chemotherapy or both. Patients who had received first-line treatment at another hospital were excluded. Results Patients demographics and clinical characteristics: between January 5, 2015 to August 31, 2019, 435 patients with a diagnosis of ovarian malignancy were registered at our center. Among them, 406 (82%) had EOC, 290 (64%) newly diagnosed, and fulfilling eligibility criteria were included in the final analysis. The median age of the cohort was 53 years (range: 21–89 years) and 157 patients (54%) were >50 years of age (the Eastern Oncology Cooperative Group Performance status was ≥ 2 in 124 patients [43%]; median duration of symptoms was 3 months; and stage III/IV: 240 [83%]). Grading of the tumor was available in 240 patients of which 219 (91%) were of high grade. Subtyping was available in 272 patients (94%) of which the serous subtype was the most common constituting 228 patients (79%).Treatment Most patients received chemotherapy (n = 283 [98%]) as the first modality of treatment (neoadjuvant/adjuvant and palliative). As neoadjuvant (NACT) in 130 patients (45%) and as adjuvant following surgery in 81 patients (29%). The most common chemotherapy regimen was a combination of carboplatin and paclitaxel in 256 patients (88%). Among 290 patients 218 (75%) underwent cytoreductive surgery. Among them, optimal cytoreduction was achieved in 108 patients (52%). Optimal cytoreduction rate (OCR) with upfront surgery and after NACT was 44 and 53%, respectively (Chi-square test: 0.86; p = 0.35).Survival The median follow-up of the study was 17 months (range: 10–28 months) and it was 20 months (range: 12–35 months) for patients who were alive. At last, follow-up, 149 patients (51%) had progressed and 109 (38%) died. The estimated median PFS and OS were 19 months (95% CI: 16.1–21.0) and 39 months (95% CI: 29.0–48.8), respectively. On multivariate analysis, primary surgery (HR: 0.1, 95% CI: 0.06–0.21; p-value: <0.001) and early-stage disease (HR: 0.2, 95% CI: 0.1–0.6; p-value 0.04) were associated with superior PFS and primary surgery (HR: 0.1, 95% CI: 0.09–0.2; p-value: <0.001) was associated with superior OS. Conclusion Primary surgery (upfront or interval) was associated with improved survival. Newer agents like bevacizumab, poly-ADP (adenosine diphosphate)-ribose polymerase inhibitors and HIPEC should be incorporated precisely into first line of therapy to improve outcomes.

Introduction: Both primary (PDS) and interval debulking surgery (IDS) have reported similar progression free survival (PFS) and overall survival (OS) rates in various studies. Complete resection of all macroscopic disease is the strongest independent variable in predicting survival in both groups. Objective: To evaluate the demographics, surgical outcomes and survival in women with advanced ovarian cancer undergoing IDS. Methods: All women with Stage IIIC or Stage IV epithelial ovarian or primary peritoneal cancer, registered at our institution from January 2010 to December 2010, who were treated with NACT followed by IDS, were included in the study. Demographic data, CA-125 levels (baseline and presurgery), chemotherapy and surgical details were collected. Progression free survival (PFS) and overall survival (OS) were calculated and Cox regression and Kaplan-Meier survival analysis were used to evaluate factors associated with survival. Results: One hundred fifty women with Stage IIIC or Stage IV epithelial ovarian or primary peritoneal cancer were included in the analysis. The mean age was 51.08 years (27 to 73 years) and 97.3% had serous histology. Eighty percent (n = 120) had Stage IIIC and 20% (n = 30) had Stage IV disease. Ninety five percent women received Carboplatin and Paclitaxel or single agent Carboplatin as NACT and the median number of NACT cycles was 3. The median baseline CA-125 was 1649.3 U/ml (Range 16.4–235,100 U/ml) and the median CA-125 post NACT was 42.75 U/ml (Range 4.4–5151 U/ml). Seventy four percent women (n = 111) underwent an optimal cytoreduction – 62.7% (n = 94) had R0 and 11.3% (n = 17) had R1 resection. Twenty six percent women (n = 39) had R2 resection. The median CA-125 post NACT was 27.3 U/ml, 36 U/ml and 99 U/ml in women with R0, R1 and R2 resection respectively and the difference was statistically significant (p < 0.0005). The CA125 response was respectively, 97.6%, 95.7% and 93.8% in R0, R1 and R2 resection (p < 0.0005). The median follow up was 42.48 months (Range 1.48–70.93 months). The median PFS was 12.06 months (95% CI 10.02-14.1) – 12.98 months (95% CI 9.7–16.2) in R0, 9.56 months (95% CI 1.7–17.4) in R1 and 6.64 months (95% CI 4.9–8.3) in women with R2 resection (p = 0.158). The median OS was 38.9 months (95% CI 31.7–46.1) – 43.3 months (95% CI 33–53.5) in R0, 46.1 months (95% CI 26.6–65.5) in R1 and 28 months (95% CI 25–30.9) in R2 resection (p = 0.121). The median PFS and OS in women undergoing optimal cytoreduction (R0 and R1) was 12.98 months (95% CI 9.86–16.1) and 43.7 months (95% CI 34.7–52.7) respectively as compared to 6.64 months (95% CI 4.95–8.32) and 28 months (95% CI 25–30.9) respectively in women with R2 resection (PFS p = 0.064, OS p = 0.04). Multivariate analysis discussing the factors affecting the probability of optimal cytoreduction and the survival will be discussed. Conclusion: In women with advanced ovarian cancer undergoing NACT followed by IDS, a high rate of optimal cytoreduction is achieved. Residual disease is a primary factor affecting the survival of these women.
