Fluorouracil, Cisplatin, Leucovorin Calcium, and Cetuximab in Treating Patients With Adenocarcinoma of the Stomach or Gastroesophageal Junction

Gastric Cancer Clinical Trial

Official title: Trial Evaluating the Efficacy and Tolerance of Perioperative Chemotherapy With 5FU-Cisplatin-Cetuximab in Adenocarcinomas of the Stomach and Gastroesophageal Junction. Phase II Single Arm, Multicenter.

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as fluorouracil, cisplatin, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving more than one drug (combination chemotherapy) together with cetuximab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these drugs after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying the side effects of giving fluorouracil, cisplatin, and leucovorin calcium together with cetuximab and to see how well they work in treating patients with adenocarcinoma of the stomach or gastroesophageal junction.

Clinical Trial Description

OBJECTIVES:

Primary

• To evaluate the objective response rate according to RECIST V1.1 criteria in patients with adenocarcinoma of the stomach or gastroesophageal junction treated with neoadjuvant chemotherapy comprising fluorouracil, cisplatin, leucovorin calcium, and cetuximab followed by surgery and adjuvant chemotherapy.

• To determine the non-toxicity rate in these patients.

Secondary

• To determine the rate of macroscopically and microscopically complete surgical resection (R0).

• To determine the overall tolerance in patients treated with this regimen.

• To determine post-operative mortality and morbidity in these patients.

• To determine the rate of recurrence at 1 and 2 years in these patients.

• To determine recurrence-free survival at 3 years in these patients.

• To determine disease-free survival at 3 years in these patients.

• To determine overall survival at 3 years in these patients.

• To determine quality of life using EORTC QLC-C30 and STO-22 questionnaires.

• To determine the correlation between the response rate and the degree of skin toxicity.

OUTLINE: This is a multicenter study.

• Neoadjuvant therapy and surgery: Patients receive leucovorin calcium IV over 2 hours, cisplatin IV, fluorouracil IV continuously over 46 hours, and cetuximab IV over 1-2 hours on day 1. Treatment repeats every 2 weeks for 6 courses in the absence of disease progression or unacceptable toxicity. Within 3-4 weeks after completing neoadjuvant chemotherapy, patients undergo surgery.

• Adjuvant therapy: Within 4-8 weeks after completing neoadjuvant chemotherapy, patients receive leucovorin calcium, cisplatin, fluorouracil, and cetuximab as in neoadjuvant therapy. Treatment repeats every 2 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.

Patients complete quality-of-life questionnaires (QLC-C30 and STO-22) periodically. Blood and tissue samples are collected periodically for correlative and translational studies.

After completing study therapy, patients are followed up every 4 months for 2 years and then every 6 months for 1 year. ;
