Ovarian neoplasms consist of several histopathologic entities, and treatment depends on the specific tumor type. Epithelial ovarian cancer comprises most malignant ovarian neoplasms (∼ 80%)1; however, other less-common pathologic subtypes must be considered in treatment guidelines. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Ovarian Cancer discuss epithelial ovarian cancer (including borderline or low malignant potential) and less-common histopathologies, including malignant germ cell neoplasms, carcinosarcomas (malignant mixed Müllerian tumors of the ovary [MMMT]), and sex cord-stromal tumors. The guidelines also discuss fallopian tube and primary peritoneal cancers, which are less-common neoplasms that are managed similarly to epithelial ovarian cancer. However, the less-common histologies of ovarian cancer are managed differently. Information on the less-common ovarian histopathologies are not published in this issue of JNCCN, but can be found online at www.NCCN.org. Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and the country's fifth most common cause of cancer mortality in women. In 2010, an estimated 21,900 new diagnoses and 13,900 deaths will occur from this neoplasm in the United States; fewer than 40% of women with ovarian cancer are cured.2,3 The incidence of ovarian cancer increases with age and is most prevalent in the eighth decade of life, with a rate of 57 per 100,000 women. The median age at diagnosis is 63 years, and 70% of patients present with advanced disease.4 Epidemiologic studies have identified risk factors for ovarian cancer. A 30% to 60% decreased risk of cancer is associated...

This selection from the NCCN Guidelines for Ovarian Cancer focuses on the less common ovarian histopathologies (LCOHs), because new algorithms were added for LCOHs and current algorithms were revised for the 2016 update. The new LCOHs algorithms include clear cell carcinomas, mucinous carcinomas, and grade 1 (low-grade) serous carcinomas/endometrioid epithelial carcinomas. The LCOHs also include carcinosarcomas (malignant mixed Müllerian tumors of the ovary), borderline epithelial tumors (also known as low malignant potential tumors), malignant sex cord-stromal tumors, and malignant germ cell tumors.

These NCCN Guidelines Insights focus on the major updates for the 2012 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Ovarian Cancer by describing how and why the new recommendations were made. The 6 update topics were selected based on recent important updates in the guidelines and on debate among panel members about recent clinical trials, and include: 1) screening, 2) diagnostic tests for assessing pelvic masses, 3) primary treatment using neoadjuvant chemotherapy, 4) primary adjuvant treatment using bevacizumab in combination with chemotherapy, 5) therapy for recurrent disease, and 6) management of drug/hypersensitivity reactions. These NCCN Guidelines Insights also discuss why some recommendations were not made (eg, panel members did not feel the new data warranted changing the guideline). See “Updates” in the NCCN Guidelines for Ovarian Cancer for a complete list of all the recent revisions.

These NCCN Guidelines Insights focus on the major updates to the 2013 NCCN Guidelines for Ovarian Cancer. Four updates were selected based on recent important updates in the guidelines and on debate among panel members about recent clinical trials. The topics include 1) intraperitoneal chemotherapy, 2) CA-125 monitoring for ovarian cancer recurrence, 3) surveillance recommendations for less common ovarian histopathologies, and 4) recent changes in therapy for recurrent epithelial ovarian cancer. These NCCN Guidelines Insights also discuss why some recommendations were not made.
