Primary mFOLFOX6 plus bevacizumab without resection of the primary tumor for patients presenting with surgically unresectable metastatic colon cancer and an intact asymptomatic colon cancer: definitive analysis of NSABP trial C-10.

ABSTRACT:

Purpose

Major concerns surround combining chemotherapy with bevacizumab in patients with colon cancer presenting with an asymptomatic intact primary tumor (IPT) and synchronous yet unresectable metastatic disease. Surgical resection of asymptomatic IPT is controversial.

Patients and methods

Eligibility for this prospective, multicenter phase II trial included Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1, asymptomatic IPT, and unresectable metastases. All received infusional fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) combined with bevacizumab. The primary end point was major morbidity events, defined as surgical resection because of symptoms at or death related to the IPT. A 25% major morbidity rate was considered acceptable.
