New update for recurrent cervical cancer - the role of bevacizumab (avastin)



About 15 to 60% of patients with cervical cancer develop recurrent of their cancer.  Patients with local/central (in the uterus, vagina) locations has potential curative chance with more radical surgery (pelvic exenteration).   Patients with multiple or distant metastases, unfortunately, are difficult to cure.

A recent study presented at the 2013 ASCO meeting (GOG 240) randomized 452 women with recurrent cervical cancer to chemotherapy with or without bevacizumab. Previous platinum-based therapy was administered with RT in 75 and 74 percent of patients, respectively.   Patients who received Bevacizumab (Avastin) has an improvement in overall survival compared to chemotherapy alone (median, 17 versus 13 months, respectively; hazard ration [HR] 0.71, 95% CI 0.54-0.94).

However, Bevacizumab also increases toxicities such as serious (grade 3/4) bleeding (5 versus 1 percent), venous thromboembolic disease (9 versus 2 percent), and the occurrence of gastrointestinal fistula (3 versus 0 percent). However, there was no difference between the study arms in quality of life up to nine months following the start of therapy. The conclusion of the study is bevacizumab has an important role in patients with recurrent cervical cancer.
