Creation and Implementation of an Environmental Scan to Assess Cancer Genetics Services at Three Oncology Care Settings.

An environmental scan (ES) is an efficient mixed-methods approach to collect and interpret relevant data for strategic planning and project design. To date, the ES has not been used nor evaluated in the clinical cancer genetics setting. We created and implemented an ES to inform the design of a quality improvement (QI) project to increase the rates of adherence to national guidelines for cancer genetic counseling and genetic testing at three unique oncology care settings (OCS). The ES collected qualitative and quantitative data from reviews of internal processes, past QI efforts, the literature, and each OCS. The ES used a data collection form and semi-structured interviews to aid in data collection. The ES was completed within 6 months, and sufficient data were captured to identify opportunities and threats to the QI project's success, as well as potential barriers to, and facilitators of guideline-based cancer genetics services at each OCS. Previously unreported barriers were identified, including inefficient genetic counseling appointment scheduling processes and the inability to track referrals, genetics appointments, and genetic test results within electronic medical record systems. The ES was a valuable process for QI project planning at three OCS and may be used to evaluate genetics services in other settings.

Catumaxomab for the treatment of malignant ascites in patients with chemotherapy-refractory ovarian cancer: a phase II study.

OBJECTIVE: The aim of this study was to investigate the efficacy and safety of intraperitoneal catumaxomab in heavily pretreated patients with chemotherapy-refractory ovarian cancer and recurrent symptomatic malignant ascites. METHODS: The study is a single-arm open-label multicenter US phase II study. Patients received 4 three-hour intraperitoneal catumaxomab infusions (10, 20, 50, and 150 µg within 10 days). The primary end point was the percentage of patients with at least a 4-fold increase in the puncture-free interval (PuFI) relative to the pretreatment interval. The main secondary end points were puncture-free survival, overall survival, ascites symptoms, and safety. Time to first therapeutic puncture (TTPu) was analyzed post hoc. RESULTS: Forty patients were screened, and 32 patients (80%) were treated. Seven patients (23%) achieved the primary end point. The median PuFI was prolonged 2-fold from 12 to 27.5 days. The median TTPu was prolonged 4-fold from 12 to 52 days. The median puncture-free survival and overall survival were 29.5 and 111 days, respectively. Nineteen patients (59%) required puncture after catumaxomab treatment. Ascites symptoms improved in most of the 13 predefined categories. At study end, most symptoms were still improved compared with screening. The most frequent treatment-related adverse events were related to cytokine release (vomiting, nausea, pyrexia, fatigue, and chills) or intraperitoneal administration (abdominal pain). Transient increases in liver parameters and transient decreases in blood lymphocytes were regularly observed but were generally without clinical relevance. CONCLUSIONS: Catumaxomab prolonged PuFI and TTPu had a beneficial effect on quality of life, as shown by the improvement in ascites symptoms, and had an acceptable safety profile, which is consistent with its mode of action.

Identification of the optimal pathway to reach an accurate diagnosis in the absence of an early detection strategy for ovarian cancer.

OBJECTIVES: There is a lack of knowledge about the health care events experienced by individual patients that lead to a definitive diagnosis of ovarian cancer (OC). The goal of this study was to describe the various pathways and to identify an optimal path to accurate diagnosis. METHODS: Women who were referred to gynecologic oncology for a suspected OC were enrolled to this study. Medical records (MRs) from all health care providers were obtained from the time the patient recalled first suspecting a health issue through the time of diagnosis to build a decision tree model. A Monte Carlo simulation was conducted of 83,000 patients to identify the optimal pathway to reach diagnosis. RESULTS: In the Monte Carlo simulation, gynecologic oncologists and gynecologists accounted for the most efficient diagnosis in over 37.9% and 29.2% of suspected OC cases, respectively, in terms of the least amount of time to reach diagnosis. Gynecologic oncologists were further associated with the fewest health care visits needed to reach diagnosis in 37% of the simulation cases; however, 23% of trials were indifferent to any specific provider. CONCLUSIONS: The decision tree provides a more comprehensive view of the complexity in reaching an accurate diagnosis of OC. This analysis was able to identify the health care utilization patterns that underlie the events that occur to reach an accurate diagnosis in the setting of a suspected OC, and was able to identify the most efficient pathways that utilize the fewest health care resources in the least amount of time.

Effects of Slide Storage on Detection of Molecular Markers by IHC and FISH in Endometrial Cancer Tissues From a Clinical Trial: An NRG Oncology/GOG Pilot Study.

We performed a pilot study in anticipation of using long-aged precut formalin-fixed paraffin-embedded tissue sections stored in real-world conditions for translational biomarker studies of topoisomerase 2A (TOP2A), Ki67, and human epidermal growth factor receptor 2 (HER2) in endometrial cancer. Formalin-fixed paraffin-embedded tissue blocks or unstained slides or both from GOG-0177 were collected centrally (1999-2000) and stored at room temperature. During 2004 to 2011 specimens were stored at 4°C. Matched pairs of stored slides and freshly cut slides from stored blocks were analyzed for TOP2A (KiS1), Ki67 (MIB1), and HER2 (HercepTest) proteins. To assess DNA stability (HER2 PathVision), fluorescence in situ hybridization (FISH) was repeated on stored slides from 21 cases previously shown to be HER2 amplified. Immunohistochemistry (IHC) staining intensity and extent, mean FISH copies/cell, and copy number ratios were compared using the κ statistic for concordance or signed rank test for differences in old cut versus new cut slides. IHC results reflected some protein degradation in stored slides. The proportion of cells with TOP2A staining was lower on average by 12% in older sections (P=0.03). The proportion of Ki67-positive cells was lower in stored slides by an average of 10% (P<0.01). Too few cases in the IHC cohort were FISH positive for any conclusions. HER2 amplification by FISH was unaffected by slide storage. We conclude that use of aged stored slides for proliferation markers TOP2A and Ki67 is feasible but may modestly underestimate true values in endometrial cancer. Pilot studies for particular storage conditions/durations/antigens to be used in translational studies are warranted.

Nomogram for Predicting Individual Survival After Recurrence of Advanced-Stage, High-Grade Ovarian Carcinoma.

OBJECTIVE: To analyze clinical prognostic factors for survival after recurrence of high-grade, advanced-stage ovarian-peritoneal-tubal carcinoma and to develop a nomogram to predict individual survival after recurrence. METHODS: We retrospectively analyzed patients treated in multicenter Gynecologic Oncology Group protocols for stage III and IV ovarian-peritoneal-tubal carcinoma who underwent primary debulking surgery, received chemotherapy with paclitaxel and a platinum compound, and subsequently developed recurrence. Prognostic factors affecting survival were identified and used to develop a nomogram, which was both internally and externally validated. RESULTS: There were 4,739 patients included in this analysis, of whom, 84% had stage III and 16% had stage IV ovarian carcinoma. At a median follow-up of 88.8 months (95% CI 86.2-92.0 months), the vast majority of patients (89.4%) had died. The median survival after recurrence was 21.4 months (95% CI 20.5-21.9 months). Time to recurrence after initial chemotherapy, clear cell or mucinous histology, performance status, stage IV disease, and age were significant variables used to develop a nomogram for survival after recurrence, which had a concordance index of 0.67. The time to recurrence alone accounted for 85% of the prognostic information. Similar results were found for patients who underwent second look laparotomy and had a complete pathologic response or received intraperitoneal chemotherapy. CONCLUSION: For individuals with advanced-stage ovarian carcinoma who recur after standard first-line therapy, estimated survivals after recurrence are closely related to the time to recurrence after chemotherapy and prognostic variables can be used to predict subsequent survival.

Patient-provider communication and perceived control for women experiencing multiple symptoms associated with ovarian cancer.

OBJECTIVES: Optimal cancer symptom management requires effective patient-health care provider (HCP) communication. The goals of this study were to 1) describe symptom experiences of women with ovarian cancer, 2) evaluate frequency of patient-HCP communication about symptoms, and 3) evaluate whether communication is associated with patients' confidence in managing symptoms. METHODS: This was a cross-sectional mailed survey study. The Symptom Experience Survey, containing valid, reliable measures of symptom severity and controllability; symptom communication; and symptom-related coping strategies, was mailed to members of the National Ovarian Cancer Coalition. Descriptive statistics, t tests, correlations, and ANCOVA were used to address study objectives. RESULTS: This analysis focuses on the 279 respondents who had active disease. The majority of women had recurrent disease (96%) and were on chemotherapy (57%). Women reported a mean of 12 concurrent symptoms. Fatigue, bowel disturbances, and peripheral neuropathies were the most severe and most noticed symptoms. Only 61% of women had discussed their most noticed symptom with an HCP in the past month, and only 50% of women reported that they had received symptom management recommendations. Women reported low levels of perceived control over symptoms (M = 1.97 on a 0-4 scale). There was a significant interaction effect for symptom discussions and management recommendations on perceived control. Women who had never received recommendations had low perceived control whether or not they had discussed their symptom with an HCP in the past month. For women who had received recommendations, those who had discussed their symptom with an HCP in the past month had higher perceived control compared to those who had not discussed their symptom. CONCLUSIONS: Women with ovarian cancer experience multiple symptoms, but many do not discuss symptoms with their HCPs and fewer report receiving symptom management recommendations. Women would benefit from more active symptom assessment and discussion of management strategies by HCPs.
