Brief Summary:
Inflammation plays an important role in the pathogenesis of peritoneal carcinosis. Patients with elevated levels of different inflammation cytokines show a worse prognosis at the time of diagnosis. In women, ovarian and colon cancer are the main causes of peritoneal carcinosis and a comparison of these two different types of peritoneal invasion have not been conducted yet. We found interesting studying the role of immune response, in particular tumour-associated antigens (TAA) that modulate the metastatic process. We will investigate also mitochondrial defects, such as mutations in mt-DNA, potentially involved in carcinogenesis.

Condition or disease Intervention/treatment
Peritoneal Carcinomatosis Ovarian Cancer Colon Cancer Procedure: Cytoreductive surgery

Detailed Description:

At the time of hospitalization all the patients will undergo a complete clinical evaluation with determination of biochemical parameters such as fasting blood glucose, blood count, hs-CRP, AST and ALT, uric acid, creatinine and BUN. An extra blood aliquot will be collected to assess the serum biomarkers under investigation.

During surgery two samples of peritoneal tissue macroscopically undamaged will be collected. On those samples will be executed separation of adipocytes cells, RNA and protein extraction for measuring of inflammatory and neoplastic biomarkers, determination of P2X7R-inflammasome activity and mitochondrial DNA analyse.

Group/Cohort Intervention/treatment
Ovarian cancer
Patients affected by ovarian cancer will be stratified according to BRCA1 and BRCA2 mutational status.
Procedure: Cytoreductive surgery
Partial removal of peritoneal tissue involved by neoplastic invasion
Other Name: Debulking

Colon cancer
Patients affected by colon cancer will be similarly stratified according to BRAF and KRAS mutational status and to the presence of low-grade or high-grade microsatellite instability (MSI).
Procedure: Cytoreductive surgery
Partial removal of peritoneal tissue involved by neoplastic invasion
Other Name: Debulking

Primary Outcome Measures :
  1. Immune biomarkers [ Time Frame: Each patients will be assessed at baseline ]
    Serum levels of CD4, CD8, CUZD1, LAG3, PD1, PDL1, IMP1 e p62/IMP2 will be determine using ELISA.

  2. Metastatic mediators [ Time Frame: Each patients will be assessed at baseline ]
    Peritoneal expression of IL6, IL2, TNFα, TGFβ1, VEGF, CD68, FGFR1, CCL2/MCP-1, CD73 will be determine using real time-PCR.

  3. P2X7R-inflammasome activity [ Time Frame: Each patients will be assessed at baseline ]
    Peritoneal expression of NLRP3-ASC will be determine using RT-PCR

Biospecimen Retention:   Samples With DNA
