Summary

This trial is testing a new way to give chemotherapy to people with stomach cancer that has spread to the lining of the abdomen.

Who is the study for?

Adults aged 18-75 with gastric or gastroesophageal junction cancer and peritoneal carcinomatosis, who've had at least three months of initial treatment without visceral metastasis. Participants need good organ function, no severe heart conditions, infections, or other cancers in the last 3 years. Pregnant women are excluded and contraception is required during the trial.

What is being tested?

The trial tests a combination of systemic chemotherapy (Leucovorin, Fluorouracil) followed by intraperitoneal Paclitaxel to see if it's safe and works for patients with stomach cancer that has spread to the lining of their abdomen.

What are the potential side effects?

Possible side effects include nausea, fatigue, low blood counts leading to increased infection risk or bleeding problems, nerve damage causing numbness or tingling sensations (neuropathy), allergic reactions, and hair loss.
