Ovarian cancer screening with the Risk of Ovarian Cancer Algorithm (ROCA): Good, bad, or just expensive?
To measure the effectiveness of ovarian cancer screening using the Risk of Ovarian Cancer Algorithm (ROCA). ⋯ The ROCA test can improve the detection of early ovarian cancer but is not practical for screening in an average-risk population. We predict the ROCA test will reduce overall ovarian cancer mortality by 6% to 9% but at a substantial cost. For ROCA to be practical, the cost would need to be reduced ten-fold and would have only a marginal impact on mortality from ovarian cancer. This model supports the FDA's criticism of the ROCA test. Ovarian cancer screening may reduce mortality from ovarian cancer but is not cost effective.

ReviewThe poly (ADP ribose) polymerase inhibitor niraparib: Management of toxicities.
Niraparib is an oral poly(ADP ribose) polymerase (PARP) inhibitor that is currently approved by the United States Food and Drug Administration (US FDA) as well as recently approved by the European Medicines Agency (EMA) for the maintenance treatment of women with recurrent ovarian cancer who are in complete or partial response to platinum-based chemotherapy. The mechanisms of action of niraparib include inhibition of PARP enzymatic activity as well as increased formation of PARP-DNA complexes through "trapping" the PARP enzyme on damaged DNA. Phase I and III studies have demonstrated activity and benefit of niraparib in both BRCA mutated (BRCAm) and BRCA wild-type (BRCAwt) cancers. ⋯ Cardiovascular toxicities include hypertension, tachycardia, as well as palpitations, and patients should be monitored for hypertension. PARP inhibitors have been associated with low risks of acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS), and the overall risk of AML and MDS is 0.9% of all patients treated with niraparib. Niraparib testing is ongoing in newly diagnosed ovarian cancer patients as maintenance therapy following completion of platinum-based chemotherapy, in BRCAwt cancers as treatment, as well as in combinations with other biologic drugs such as immunotherapy and anti-angiogenic agents.

Patterns of palliative care referral in ovarian cancer: A single institution 5 year retrospective analysis.
The American Society of Clinical Oncology recommends that patients with advanced cancer receive dedicated palliative care services early in their disease course. This investigation serves to understand how palliative care services are utilized for ovarian cancer patients in a tertiary referral center. ⋯ The outcomes in this study suggest a late use of palliative care that is reactionary to patient needs and not a routine component of ovarian cancer care as national guidelines recommend.

Multicenter StudyPhase I combination study of the PARP inhibitor veliparib plus carboplatin and gemcitabine in patients with advanced ovarian cancer and other solid malignancies.
Determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of veliparib combined with carboplatin and gemcitabine in patients with advanced ovarian cancer and other nonhematologic malignancies. ⋯ Veliparib plus carboplatin/gemcitabine is tolerated, with a safety profile similar to carboplatin and gemcitabine alone. Combination therapy demonstrated promising preliminary antitumor activity in platinum-sensitive ovarian cancer patients with germline BRCA mutations. Trial registration ID: NCT01063816.

Minimally invasive hysterectomy surgery rates for endometrial cancer performed at National Comprehensive Cancer Network (NCCN) Centers.
Minimally invasive surgery (MIS) is a quality measure for endometrial cancer (EC) established by the Society of Gynecologic Oncology and the American College of Surgeons. Our study objective was to assess the proportion of EC cases performed by MIS at National Comprehensive Cancer Network (NCCN) centers and evaluate perioperative outcomes. ⋯ At NCCN-designated centers, the MIS hysterectomy rate in EC is higher than the published national average, with low perioperative complications. Previously identified disparities of age, race, and BMI were not observed. A proposed MIS hysterectomy benchmark of >80% in EC care is feasible when performed at high volume centers.
