Trial Outcomes & Findings for Bevacizumab, Fluorouracil, Leucovorin Calcium, and Oxaliplatin Before Surgery in Treating Patients With Stage II-III Rectal Cancer (NCT NCT01871571)

NCT ID: NCT01871571

Last Updated: 2026-07-01

Results Overview

Pathological Complete Response (pCR) after neoadjuvant therapy in pathological specimen. Pathological Complete Response (pCR) is the absence of all invasive cancer in the breast and lymph nodes after neoadjuvant therapy, meaning all cancer cells are eliminated. This outcome is a strong predictor of improved survival. Evaluating pCR provides a rapid assessment of a patient's likely response to therapy and can help guide future treatment decisions.

Measure
Treatment (Bevacizumab, mFOLFOX7)
Patients receive bevacizumab IV over 30-90 minutes, oxaliplatin IV over 2 hours, leucovorin calcium IV, and fluorouracil IV continuously over 46-48 hours on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity. Within 6-8 weeks after treatment, patients undergo surgery. bevacizumab: Given IV oxaliplatin: Given IV leucovorin calcium: Given IV fluorouracil: Given IV laboratory biomarker analysis: Correlative studies

SECONDARY outcome

Timeframe: Up to 3 years

Number of cancer patients who experience a return of their cancer in the original tumor site or in the nearby lymph nodes following initial treatment. It is a measure of how often cancer returns to the local area where it started, rather than spreading to distant organs.
