Summary
This pilot clinical trial studies genetic analysis-guided irontecan hydrochloride dosing of modified fluorouracil, irinotecan hydrochloride, leucovorin calcium, oxaliplatin (mFOLFIRINOX) in treating patients with gastroesophageal or stomach cancer that has spread from where it started to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, leucovorin calcium, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Leucovorin calcium may also help fluorouracil work better. Genetic analysis may help doctors determine what dose of irinotecan hydrochloride patients can tolerate.
Description
PRIMARY OBJECTIVES:
I. To determine the residual tumor (R) 0 resection rate. II. To determine the pathologic complete response (pCR) rate of up to 36 patients treated with 4 cycles of neoadjuvant mFOLFIRINOX (UGTA1A1 genotype-dosed irinotecan [irinotecan hydrochloride]) regimen.
SECONDARY OBJECTIVES:
I. Response rate (radiographic [computed tomography (CT)], and metabolic (positron emission tomography [PET] maximum standardized uptake value [SUVmax]) to chemotherapy.
II. Chemotherapy-related toxicity. III. Surgical morbidity. IV. Overall survival (OS) measured from the time of histologic diagnosis. V. Disease-free survival measured from the time of histologic diagnosis. VI. Pattern of recurrence (distant, locoregional, both). VII. Human epidermal growth factor receptor 2 positive (HER2+) vs HER2 negative (-) difference in clinical outcomes.
- OUTLINE
PREOPERATIVE THERAPY: Patients receive oxaliplatin intravenously (IV) over 2 hours, leucovorin calcium IV over 2 hours, irinotecan hydrochloride IV over 90 minutes, and fluorouracil IV over 46 hours continuously on day 1. Courses repeat every 2 weeks for 4 courses in the absence of disease progression or unacceptable toxicity.
SURGERY: Patients undergo surgery.
POST-OPERATIVE THERAPY: Beginning 5-10 weeks after surgery, patients receive oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, irinotecan hydrochloride IV over 90 minutes, and fluorouracil IV over 46 hours continuously on day 1. Courses repeat every 2 weeks for 4 more courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
