Neoadjuvant immunotherapy leads to pathological responses in MMR-proficient and MMR-deficient early-stage colon cancers.

PD-1 plus CTLA-4 blockade is highly effective in advanced-stage, mismatch repair (MMR)-deficient (dMMR) colorectal cancers, yet not in MMR-proficient (pMMR) tumors. We postulated a higher efficacy of neoadjuvant immunotherapy in early-stage colon cancers. In the exploratory NICHE study (ClinicalTrials.

Adjuvant Hepatic Arterial Infusion Pump Chemotherapy After Resection of Colorectal Liver Metastases: Results of a Safety and Feasibility Study in The Netherlands.

Background: The 10-year overall survival with adjuvant hepatic arterial infusion pump (HAIP) chemotherapy after resection of colorectal liver metastases (CRLMs) was 61% in clinical trials from Memorial Sloan Kettering Cancer Center. A pilot study was performed to evaluate the safety and feasibility of adjuvant HAIP chemotherapy in patients with resectable CRLMs.

Study Design: A phase II study was performed in two centers in The Netherlands.

Bevacizumab combined with docetaxel, oxaliplatin, and capecitabine, followed by maintenance with capecitabine and bevacizumab, as first-line treatment of patients with advanced HER2-negative gastric cancer: A multicenter phase 2 study.

Background: The current study was a multicenter, single-arm, phase 2 study performed to investigate the feasibility and efficacy of bevacizumab combined with docetaxel, oxaliplatin, and capecitabine (B-DOC) in patients with advanced human epidermal growth factor receptor 2 (HER2)-negative, previously untreated, gastric or gastroesophageal adenocarcinoma.

Methods: Tumor HER2 status was determined centrally. Patients received 6 cycles of bevacizumab at a dose of 7.

Trastuzumab and bevacizumab combined with docetaxel, oxaliplatin and capecitabine as first-line treatment of advanced HER2-positive gastric cancer: a multicenter phase II study.

Objective: To investigate the efficacy of bevacizumab and trastuzumab combined with docetaxel, oxaliplatin, and capecitabine (B-DOCT) as first-line treatment of advanced human epidermal growth factor receptor 2 (HER2)-positive gastric cancer (GC).

Methods: In this multicentre, single-arm, phase II study, tumor HER2 status was determined centrally prior to treatment. Patients with advanced HER2-positive adenocarcinoma of the stomach or gastroesophageal junction (immunohistochemistry 3+ or immunohistochemistry 2+/silver in-situ hybridization positive) were treated with six cycles of bevacizumab 7.
