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. 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. Secondary end points included overall survival (OS) and minor morbidity related to IPT requiring hospitalization, transfusion, or nonsurgical intervention. Ninety patients registered between March 2006 and June 2009: 86 were eligible with follow-up, median age was 58 years, and 52% were female. Median follow-up was 20.7 months. There were 12 patients (14%) with major morbidity related to IPT: 10 required surgery (eight, obstruction; one, perforation; and one, abdominal pain), and two patients died. The 24-month cumulative incidence of major morbidity was 16.3% (95% CI, 7.6% to 25.1%). Eleven IPTs were resected without a morbidity event: eight for attempted cure and three for other reasons. Two patients had minor morbidity events only: one hospitalization and one nonsurgical intervention. Median OS was 19.9 months (95% CI, 15.0 to 27.2 months). This trial met its primary end point. Combining mFOLFOX6 with bevacizumab did not result in an unacceptable rate of obstruction, perforation, bleeding, or death related to IPT. Survival was not compromised. These patients can be spared initial noncurative resection of their asymptomatic IPT.
