STELLA, MARTINA. « Identification of molecular alterations associated with the progression of clear cell Renal Cell Carcinoma by mass spectrometric approaches ». Doctoral thesis, Università degli Studi di Milano-Bicocca, 2019. http://hdl.handle.net/10281/241159.
Texte intégralRenal Cell Carcinoma (RCC) is the most frequent form of kidney cancer and approximately 80% of cases are defined as clear cell RCC (ccRCC). Partial or total nephrectomy remain the gold standard for the routine treatment of ccRCC, therefore a better understanding of molecular aspects associated to tumour progression could be useful for its diagnosis, prognosis and treatment. Nowadays proteomic approaches are more readily used to investigate the processes that drive disease onset and progression. In this work, two complementary technologies, Matrix-Assisted Laser Desorption/Ionisation – Mass Spectrometry Imaging (MALDI-MSI) and nLC-ESI MS/MS, were used to detect alterations within tumour lesions and to perform protein identification and quantification. Likewise, employing both tissue and body fluids (urine-plasma) ensures a strong correlation with the disease, a high degree of lesion specificity whilst at the same time enables the use of more readily accessible samples. Therefore, the aim of this study was to investigate proteomic changes in different human specimens related to early pathological modifications and ccRCC progression. Our study on ccRCC started with the evaluation of the information that can be obtained from urine and plasma from patients with ccRCC. Then, MALDI-MSI was used to evaluate the spatial distribution of tryptic peptides directly on tissue, and the molecular data has been correlated to morphological annotation (grade). Moreover, in situ findings has been combined with those obtained from tissue homogenates and better understanding of molecular changes among the four grades has been provided. Finally, we demonstrate the possibility to detect in urine alterations determined by the stage of the lesion. Further work related to the study of ccRCC tissue is currently ongoing. At first, the biological role of the proteins resulted to be altered and the pathways involved in grade progression are under investigation. Preliminary data suggest the essential role of metabolic alterations in ccRCC progression. Moreover, a protocol for realised N-glycans analysis directly on tissue has been optimised and this protocol will be used to evaluate N-glycans trait on different ccRCC grade areas. In conclusion, it is hoped that the data obtained along with the additional work planned, could better clarify the biological processes involved in ccRCC progression.

Texte intégralBladder cancer is the second most frequent tumour of the genitourinary tract. In our days it is necessary to identify new prognostic markers of bladder cancer that help clinicians to identify which patients should be treated earlier and in an intensive way. Tumour development is angiogenesis dependent. Tumour angiogenesis, expressed as mean micro vessel density in histological preparations, proved to be in several studies an independent prognostic marker in bladder cancer. VEGF is a multifunctional cytokine that plays an outstanding role in angiogenesis.Hypothesis: Angiogenesis is a necessary process in the development and progression of bladder cancer, in which VEGF could play an outstanding role.Objective: To determine the serum concentrations of VEGF in a primary bladder cancer series and in a healthy (non cancer) control group, and to verify if there is a relationship of VEGF serum concentrations at diagnosis with stage, grade, urinary cytology, number of tumours at the first transurethral resection (TUR), disease - free survival and mortality in the first three years of follow up. Material and methods: This study comprised 52 patients with bladder cancer and 26 healthy controls. Serum concentrations of VEGF were assessed by the Quantikine quantitative sandwich enzyme human vascular endothelial growth factor immunoassay kit (R & D Systems, Abington, United Kingdom) according to manufacturer instructions.Results: Mean serum concentrations of VEGF in the study (bladder cancer) group where significantly higher than in controls. There were no significantly relationships of serum concentrations of VEGF with tumour stage, grade, number of tumours at the first TUR, number of relapses, urinary cytology, disease free survival or mortality.Conclusions: Patients with bladder cancer show higher serum concentrations of VEGF than healthy controls.There was no significant relationship of serum concentrations of VEGF with recognized prognostic factors of bladder cancer.The serum concentrations of VEGF do not provide prognostic information in bladder cancer.

Texte intégralMETODOLOGIA. Diseño del estudio y objetivos: I- Etapa experimental: Validación del método de cuantificación mediante un maniquí en cuyo interior se simularon lesiones con esferas de diferente volumen y actividad que fueron colocadas en diversas posiciones. II. Etapa clínica: Determinar la aplicabilidad de los ICV en el estudio de pacientes con glioma cerebral. Se diseñó un estudio observacional, descriptivo-transversal (fase de inclusión de pacientes entre los años 1997 y 2001 en dos centros sanitarios de tercer nivel). Población de estudio: GRUPO I (75 pacientes (p) estudiados previamente a la realización de la cirugía, para la valoración del grado de malignidad histológica), GRUPO II (45 p estudiados en la primera semana postcirugía para comprobar el grado de resección tumoral). GRUPO III (24 p con sospecha de recidiva versus necrosis o gliosis posterapéutica). GRUPO IV (20 p en los que se valoró el grado de respuesta tras realizar una 1ª y 2ª línea de quimioterapia -QT- en relación a los criterios de Macdonald). Protocolo de estudio: SPECT precoz (P) y tardío (T) adquirido a los 15¨y 2-3 h p.i de 148 MBq de 201Tl. ICV analizados: I1P e I1T, I2P e I2T, I3P e I3T, IR (índice de retención). Análisis estadístico: Sensibilidad (S), especificidad (E), valor predictivo positivo y negativo (VPP y VPN), o grado de acuerdo del SPECT 201Tl respecto al diagnóstico histológico definitivo o en su defecto, respecto a las técnicas de neuroimagen morfológica (TC y/o RM) o la evolución clínica. Análisis del área bajo la curva ROC como medida de validez global del SPECT 201Tl. Prueba U de Mann-Whitney para la comparación de los ICV entre grupos. Nivel de significación p< 0,05.
Resultados. I Validación del método de cuantificación. El volumen cuantificado (Vc) y el volumen real (VR) de las esferas se encontraban relacionados según un modelo de regresión de tipo lineal: VR= 0,418Vc-22 (r=0,985; p<0,001). El error medio asociado al ajuste fue del 14%. La variabilidad intraobservador en la delimitación manual de la ROI (región de interés) de las esferas fue del 5,9%.
II. Resultados en la población de estudio. GRUPO I: La S del SPECT 201Tl fue del 92%, el VPP del 100%. Se observaron diferencias significativas entre glioblastomas multiformes (GBM) y astrocitomas de bajo grado (ABG) en todos los ICV, entre astrocitomas anaplásicos (AA) y ABG en todos los ICV excepto en el I3T, entre GBM y AA solamente en el I1P y I1T. La mejor exactitud diagnóstica se observó para el I1P y el I1T -95,8% y 92,3%- (área bajo la curva ROC). GRUPO II: La S del SPECT 201Tl para el diagnóstico de tumor residual fue del 90,9 % y la E del 78,3 %, el VPP y VPN del 80 % y del 90 %. GRUPO III: Se demostró una S y E del SPECT 201Tl para el diagnóstico de recidiva del 72,7% y 76,9%. GRUPO IV: El SPECT 201Tl coincidió con el "status" clínico (criterios de Mcdonald) en el 90% de los casos tras la 1ª línea de QT y en el 94,4 % tras tratamiento de segunda línea.
Conclusiones. Los datos demuestran una buena fiabilidad del método de cuantificación para su aplicación en clínica. Los ICV orientan sobre la agresividad histológica de los gliomas permitiendo la diferenciación entre las lesiones de alto y bajo grado, y dentro de las primeras, entre AA y GBM. En el período postquirúrgico inmediato la ausencia de captación de 201Tl indica que el tumor ha sido totalmente resecado y no hay evidencia de tumor residual. Durante el seguimiento la valoración cualitativa y semicuantittiva (ICV) de la captación de 201Tl en el lecho tumoral permite la diferenciación entre tejido tumoral viable y radionecrosis o fibrosis posterapéutica. El tipo de respuesta observado por SPECT 201Tl se correlaciona adecuadamente con la respuesta clínica valorada según los criterios de Macdonald.
"Diagnostic value of volumetric uptake indexes obtained by 201Tl chloride scintitomography (SPECT) for the study of histologic grade of glial brain tumours, and its usefulness in the assessment of therapeutic response"
HYPOTHESIS. To assess the diagnostic value of 201Tl uptake indexes calculated in the full tumour volume in patients with glioma. In order to achieve our objective a quantification method that allows to determine tumour volume by SPECT study was performed and also volumetric uptake indexes (VUI) were calculated from these volumes.
METHODS. Study design and objectives: I- Experimental phase: Validation of the quantification method simulating brain lesions inside a phantom using metacrilate spheres with different volume and activity which were placed in several locations. II. Clinical phase: To determine the applicability of VUI in patients with glioma. An observational, descriptive, cross-sectional study was designed (patients included from 1997 to 2001). Population of study: GROUP I (75 patients (p) studied before surgery to assess histologic grade), GROUP II (45 p studied during the first week after surgery to check the degree of tumour resection). GROUP III (24 p under suspicion of recurrence versus postherapeutic necrosis or glial reaction). GROUP IV (20 p treated with a 1st and 2nd line of chemotherapy (ChT) were studied to evaluate therapeutic response following Macdonald´s criteria). Study protocol: early (E) and delayed (D) SPECT studies were acquired at 15´ and 2-3 h p.i 148 MBq 201Tl. VUI analyzed: EUI1 & DUI1, EUI2 & DUI2, EUI3 & DUI3, RI (retention index). Statistical analysis: Sensitivity (S), specificity (Sp), positive and negative predictive values (PPV & NPV), or degree of agreement of 201Tl SPECT regarding the histologic diagnosis, or if not available, regarding morphologic neuroimaging (CT and/or MRI) or clinical follow-up. Global accuracy of the SPECT 201Tl was analyzed using area under ROC curve. U de Mann-Whitney test was used to compare the VUI values between groups. Level of significance: p< 0,05.
RESULTS. I Validation of the quantification method. The quantified volume (Vq) and the real volume (VR) of the spheres correlated according to a linear regression model: VR= 0,418Vq-22 (r=0,985; p<0,001). The adjusted average error was 14%. The intraobserver variability of manual ROI (region of interest) drawing was 5,9%.
II. Results in the population of study. GROUP I: The SPECT 201Tl S was 92% and the PPV 100%. Significant differences were observed between glioblastoma multiforme (GBM) and low grade astrocitoma (LGA) in all the VUI, also between anaplasic astrocitomas (AA) and LGA in all the VUI except in DUI3, and between GBM and AA only in EUI1 and DUI1. The best diagnostic accuracy was observed for EUI1 and DUI1 -95,8% and 92,3%-(area under ROC curve). GROUP II: The SPECT 201Tl S for the diagnosis of residual tumour was 90,9%, Sp 78,3%, PPV and NPV 80% and 90%. GROUP III: The SPECT 201Tl S and Sp for the diagnosis of recurrence was 72,7% and 76,9%. GROUP IV: SPECT 201Tl agreed with the clinical "status" (Mcdonald's criteria) in 90% of the cases after 1st line of QhT and in 94,4% after second line treatment.
CONCLUSIONS. Data shows the reliability of the quantification method for clinical application. Increased VUI value points to high histologic aggressiveness of gliomas allowing to differentiate between high and low grade tumours, and within high grade gliomas, between AA and GBM. In the immediate postoperative period the absence of 201Tl uptake showed that the lesion had been totally removed and there was no evidence of residual tumor. During the follow-up the qualitative and semiquantitative assessment (VUI) of 201Tl uptake in the tumor bed makes it possible to differentiate between viable tumour and radionecrosis or postherapeutic gliosis. The type of response observed by 201Tl SPECT adequately correlated with the clinical response according to Macdonald's criteria.
