I have recently finished chemotherapy and Dr has recommended Avastin as a maintenance treatment. I am resistant to this because of the possibility of fistulas for patients with recurrence at field of prior radiation for metastatic cervical cancer. In one trial the frequency of GI-vaginal fistula's in this group was 16.7%. Has any one using Avastin run into this? There are also possibilities for venous thromboembolic reactions (I have already had DVT's from cancer treatment) and serious ocular reactions such as increased intraocular pressure.(I have glaucoma)
