Ovarian Cancer: Avastin Dosing and Usage
Stage III or IV ovarian cancer (OC) after primary surgery
Avastin, in combination with carboplatin and paclitaxel, followed by Avastin as a single agent, is indicated for the treatment of patients with stage III or IV epithelial ovarian, fallopian tube, or primary peritoneal cancer following initial surgical resection.
Recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer (rOC)
Avastin, in combination with paclitaxel, pegylated liposomal doxorubicin, or topotecan, is indicated for the treatment of patients with platinum-resistant recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer who received no more than 2 prior chemotherapy regimens.
Avastin, in combination with carboplatin and paclitaxel, or with carboplatin and gemcitabine, followed by Avastin as a single agent, is indicated for the treatment of patients with platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer.
For your patients with stage III or IV ovarian cancer, add Avastin at cycle 2 after primary surgery and continue with single-agent Avastin for up to 22 cycles

The FDA-approved Prescribing Information addresses the duration of Avastin treatment: Patients should continue treatment until disease progression or unacceptable toxicity.
Important treatment considerations—Women of childbearing potential
- Avastin increases the risk of ovarian failure and may impair fertility. Inform females of reproductive potential of the risk of ovarian failure prior to the first dose of Avastin
- Long-term effects of Avastin exposure on fertility are unknown
- Patients should also use effective contraception during treatment and for 6 months following the last dose of Avastin
- Nursing mothers should not breastfeed during treatment and for 6 months following their last dose of treatment
Important treatment considerations—dose modifications
No dose reductions for Avastin are recommended.
