To retrospectively characterize the molecular features of Non-Small Cell Lung Carcinomas (NSCLC) with peritoneal carcinomatosis (PC), clinicopathological data of 12 patients diagnosed with NSCLC and PC between 2007 and 2016 were collected. Immunohistochemistry and Next Generation Sequencing (NGS) were performed on cases with available material. PC was the initial presentation of NSCLC in 17% of the cases. Overall, patients with PC displayed a poor median survival of 12 weeks. Histology was adenocarcinoma in 11 cases. 37.5% of cases showed PD-L1 immunostaining positivity (50% cut-off). ALK and ROS1 immunostainings were negative. Using NGS, we identified 17 molecular alterations in 9 genes (TP53, KRAS, STK11, BRAF, EGFR, DDR2, ERBB4, SMAD4, CTNNB1) in 88.9% of adenocarcinomas. To the best of our knowledge, 5 of these variants are not referenced in the literature. In conclusion, PC might be the initial presentation of NSCLC. Molecular profiling of our cases did not find any effective targetable alteration, except from high PD-L1 expression.

: This study aimed to assess the diagnostic accuracy and prognostic significance of staging laparoscopy (SL) compared to computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) in gastric cancer staging. We evaluated the ability of SL to detect occult peritoneal metastases and influence of SL on survival outcomes across cancer stages and treatment approaches. : In this retrospective cohort study, 95 patients with gastric cancer underwent preoperative assessment using CT, PET-CT, and SL between 2018 and 2024.

There is no reliable immune scoring system that can help us predict the postoperative outcomes of colorectal cancer patients with peritoneal metastases after cytoreductive surgery. In this cohort, the aims were (1) to evaluate the postoperative morbidity, mortality and surgical oncological outcomes in colorectal cancer patients with peritoneal metastasis; (2) to compare oncological and postoperative outcomes of colon cancer patients with peritoneal metastasis and rectal cancer patients with peritoneal metastasis; and (3) to assess the prognostic value of the modified Glasgow Prognostic Score (mGPS) and the CRP-albumin ratio (CAR). : A prospectively maintained database of 258 patients who underwent cytoreductive surgery for peritoneal metastases of colorectal origin between 2007 and 2024 was analyzed.

Background: Patients with peritoneal carcinomatosis often experience intestinal failure throughout the course of their disease, and total parenteral nutrition (TPN) can be used as a temporary solution or as a bridge to definitive cytoreductive surgery. Guidelines for TPN are well established for inpatients and in 2014, guidelines were established for the initiation of TPN for outpatients in a home setting. However, the safety and efficacy of home start TPN in advanced oncology patients remain unknown.

Advances in cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) and pressurized intraperitoneal aerosol chemotherapy (PIPAC) have improved outcomes for selected patients with peritoneal surface malignancies (PSMs). This retrospective study analyzed 743 PSM patients treated at Fondazione Policlinico Universitario Agostino Gemelli from January 2016 to February 2024. The primary aim was to assess median overall survival (mOS), median disease-free survival (mDFS), and median progression-free survival (mPFS) stratified by tumor origin.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) has become standard treatment for peritoneal cancers and metastases, significantly enhancing survival rates. This study evaluated the relationship between tumor burden, hemodynamic management, and postoperative outcomes after CRS-HIPEC. This study included 203 patients undergoing CRS-HIPEC.
