- The 4th Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup was held in Vancouver, Canada, in June 2010. Representatives of 23 cooperative research groups studying gynecologic cancers gathered to establish international consensus on issues critical to the conduct of large randomized trials. Group C, 1 of the 3 discussion groups, examined recurrent ovarian cancer, and we report the consensus reached regarding 4 questions. These included the following: (1) What is the role of cytoreductive surgery for recurrent ovarian cancer? (2) How do we define distinct patient populations in need of specific therapeutic approaches? (3) Should end points for trials with recurrent disease vary from those of first-line trials? (4) Is CA-125 progression alone sufficient for entry/eligibility into clinical trials?

- Objective: To describe and analyze observed hypersensitivity reactions (HSR) from the randomized, multicenter phase III CALYPSO trial that evaluated the efficacy and safety of the combination of carboplatin and pegylated liposomal doxorubicin (CD) compared with standard carboplatin–paclitaxel (CP) in patients with platinum-sensitive relapsed ovarian cancer (ROC). Methods: HSR documented within case report forms and SAE reports were specifically analyzed. Analyses were based on the population with allergy of any grade and for grade > 2 allergy. Results: Overall 976 patients were recruited to this phase III trial, with toxicity data available for 466 and 502 on the CD and CP arms, respectively. There was a 15.5% HSR rate associated with CD (2.4% grade > 2) versus 33.1% with CP (8.8% grade > 2), p < 0.001. HSRs occurred more often during first cycle in the CD (46%) arm than in the CP arm (16%). Multivariate predictors of allergy were chemotherapy regimen and age; patients randomized to CD and patients ≥ 70 years old on CP had less allergy. Few patients (< 6%) stopped treatment due to allergy. Allergy rates were higher in patients who did not receive prior supportive treatment; however there was no relationship between allergy and the type of carboplatin product received, or response rate. Conclusions: Use of PLD with carboplatin instead of paclitaxel and older age were the only 2 factors predicting a low rate of HSRs in patients with ROC. CD has previously demonstrated superior progression-free survival and therapeutic index than CP. Taken together these data support the use of CD as a safe and effective therapeutic option for platinum-sensitive ROC.

- BACKGROUND: The CA-125 tumor marker has limitations when used to distinguish between benign and malignant ovarian masses. We therefore establish likelihood curves of six subgroups of ovarian pathology based on CA-125 and menopausal status.METHODS: This cross-sectional study conducted by the International Ovarian Tumor Analysis group involved 3,511 patients presenting with a persistent adnexal mass that underwent surgical intervention. CA-125 distributions for six tumor subgroups (endometriomas and abscesses, other benign tumors, borderline tumors, stage I invasive cancers, stage II-IV invasive cancers, and metastatic tumors) were estimated using kernel density estimation with stratification for menopausal status. Likelihood curves for the tumor subgroups were derived from the distributions.RESULTS: Endometriomas and abscesses were the only benign pathologies with median CA-125 levels above 20 U/mL (43 and 45, respectively). Borderline and invasive stage I tumors had relatively low median CA-125 levels (29 and 81 U/mL, respectively). The CA-125 distributions of stage II-IV invasive cancers and benign tumors other than endometriomas or abscesses were well separated; the distributions of the other subgroups overlapped substantially. This held for premenopausal and postmenopausal patients. Likelihood curves and reference tables comprehensibly show how subgroup likelihoods change with CA-125 and menopausal status.Conclusions and Impact: Our results confirm the limited clinical value of CA-125 for preoperative discrimination between benign and malignant ovarian pathology. We have shown that CA-125 may be used in a different way. By using likelihood reference tables, we believe clinicians will be better able to interpret preoperative serum CA-125 results in patients with adnexal masses.
