Complete pathological response after chemotherapy or immune checkpoint inhibitors in deficient MMR metastatic colorectal cancer: Results of a retrospective multicenter study.

About 5% of the patients with metastatic colorectal cancers (mCRC) present microsatellite instability (MSI)/deficient mismatch repair system (dMMR). While metastasectomy is known to improve overall and progression-free survival in mCRC, specific results in selected patients with dMMR/MSI mCRC are lacking. Our study aimed to describe metastasectomy results, characterize histological response and evaluate pathological complete response (pCR) rate in patients with dMMR/MSI mCRC.

Liver metastases in prostate carcinoma: clinical characteristics and outcome.

Objective: To assess the clinical characteristics and outcome of patients with liver metastases in prostate carcinoma.

Patients And Methods: From January 1995 to December 2005, 345 patients with metastatic prostate cancer were prospectively recorded in the database of the Montpellier Cancer Centre, France. The clinical characteristics and outcome of 28 patients who developed liver metastases during the course of the disease were analysed.
