Proton Pump Inhibitors and Oncologic Treatment Efficacy: A Practical Review of the Literature for Oncologists.

Proton pump inhibitors (PPIs) are the most commonly used anti-acid drugs worldwide, including among cancer patients. However, drug-drug interactions between PPIs and other agents may lead to decreased drug absorption with possible reduced therapeutic benefit, or even increased toxicity. Unfortunately, only scarce data exist regarding the safety of concomitant PPI use with anti-cancer agents.

Complete Response for More than 4 Years following Neoadjuvant FOLFOX and Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy for a Patient with Advanced Gastric Cancer with Extensive Peritoneal Carcinomatosis.

Background: Peritoneal carcinomatosis is usually a terminal disease with short median survival in patients with gastric cancer. Systemic FOLFOX is one of the most used regimens in the first-line treatment of metastatic gastric cancer. However, there is scarce evidence that cytoreductive surgery (CRS) and intraperitoneal heated chemotherapy (HIPEC) improves oncological outcomes of patients with advanced gastric cancer.
