Mechanisms to increase cascade testing in hereditary breast and ovarian cancer: Impact of introducing standardized communication aids into genetic counseling.

AIM: Precancer identification of women with hereditary breast and ovarian cancer (HBOC) could prevent 20% of these ovarian cancers. The objective was to determine whether standardized Facing Our Risk of Cancer Empowered (FORCE) materials are acceptable, improve knowledge of HBOC and increase disclosure to family members. METHODS: A prospective cohort of women with breast or ovarian cancer was identified prior to genetic testing. Subjects completed a baseline knowledge survey and were provided three communication aids. Knowledge, acceptability and communication to family members were reassessed at 6 months and compared to a retrospective cohort who had undergone genetic testing for breast or ovarian cancer prior to the intervention. The primary outcome was increase in HBOC knowledge, requiring 20 pre- and postknowledge scores to detect a 10% difference. RESULTS: Forty women were enrolled. The median age at cancer diagnosis was 50 years and 55% had a family history of breast or ovarian cancer. Though subjects found the resources acceptable, knowledge scores did not improve after their use. Disclosure rates were of no different between cohorts (83% preintervention vs 77% postintervention, P = 0.26) though there was an increase in deleterious mutation carriers, 0% (0/6) preintervention vs 100% (22/22) postintervention. Rates of subsequent testing in relatives were low in both preintervention and postintervention cohorts (0% vs 4.5%). CONCLUSION: Inclusion of standardized communication tools is acceptable to patients. Knowledge did not improve after their use. In deleterious mutation carriers, disclosure rates increased postintervention.

Provider-Identified Barriers to Cervical Cancer Screening and Perceptions Toward Self-Collection of Human Papillomavirus in Southwest Virginia.

OBJECTIVE: To explore health care workers identified barriers to cervical cancer screening in rural Southwest Virginia. DESIGN AND SAMPLE: A descriptive study utilizing telephone-based structured interviews and conventional content analysis. All free and federally funded health clinics within a 75 mile radius of Virginia's health Districts 1, 2, and 3 were contacted for participation in the study. MEASURES: Organizational information such as composition of clinical staff, services provided, cost of services, recorded compliance with current guidelines, and assessed individual barriers to accessing screening within the community. RESULTS: With a 27% response rate, all but one clinic offered cervical cancer screening. The most common barriers to cervical cancer screening identified were lack of education and cost. The most important efforts to detect unscreened women and increase screening would involve clinic-based tracking, education and advertisements. Seventy percent of respondents felt that self-collection of HPV would be at least somewhat acceptable in their communities. CONCLUSIONS: Public health nursing implications for the barriers of lack of education and high cost were found in this study. In Southwest Virginia, self-collection of HPV was perceived as acceptable by health care workers in the community, and might represent an avenue for increased outreach and education.

Lean methodology improves efficiency in outpatient academic Gynecologic Oncology clinics.

OBJECTIVES: Patient satisfaction scores may be used as a measure of quality of care, but outpatient scores are significantly and negatively affected by long clinic wait times. Patients in academic Gynecologic Oncology clinic at UVA for chemotherapy visits experience multiple wait times during a complex multipurpose visit. The purpose of this study was to utilize Lean methodology to identify variability in patient flow in order to guide solutions for improvement. METHODS: A value stream map of our clinic process was created. Patient surveys and clinical timestamps were used to identify which visit components were contributing to delays and to identify process variability. After results were analyzed, a process change was instituted, with the patient surveys then repeated. RESULTS: In the first phase, women experienced short wait times for the first appointment, but the average wait time between appointments gradually increased, with a peak mean wait time of 65 min (range 38-108) just prior to drug infusion. The total mean wait time (including all visits) was 119 min (range 81-154). After instituting process intervention, the overall wait time decreased significantly (82 vs 119 min, p=0.001), but was still affected by aspects of the process that were outside of the investigators' control. CONCLUSIONS: Analyzing patient flow through an academic Gynecologic Oncology clinic can elucidate inefficiencies and guide improvements. Change in process can meaningfully affect overall waiting time. Next steps include instituting a more global change in process, as well as linking results to patient satisfaction scores.

An Exploratory Study of Neoadjuvant Cetuximab Followed by Cetuximab and Chemoradiotherapy in Women With Newly Diagnosed Locally Advanced Cervical Cancer.

OBJECTIVES: This study explored the feasibility of cetuximab with chemoradiation in women with cervical carcinoma and evaluated fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) to assess early response to cetuximab (NCT00292955). PATIENTS AND METHODS: Eligible patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB-IVB invasive carcinoma of the uterine cervix were treated on 1 of 3 dose levels (DL). DL1 consisted of neoadjuvant cetuximab, then concurrent radiotherapy with cetuximab 250 mg/m2/cisplatin 40 mg/m2, followed by weekly cetuximab. DL2 consisted of radiotherapy with cetuximab 200 mg/m2 and cisplatin 30 mg/m2. DL3 consisted of radiotherapy with cetuximab 250 mg/m2 and cisplatin 30 mg/m2. Patients underwent 18F-FDG-PET/CT before treatment, after neoadjuvant cetuximab, and at the end of treatment. RESULTS: Of the 21 patients enrolled, 9, 3, and 9 were treated in DL1, DL2, and DL3, respectively. DL1 required dose reductions due to gastrointestinal toxicities. DL2 and 3 were tolerated with 1 dose-limiting toxicity (grade 4 renal failure) at DL3. Following 3 weekly treatments of neoadjuvant cetuximab in DL1, 7 patients had maximum standardized uptake value changes on 18F-FDG-PET/CT consistent with response to cetuximab. Of the 12 patients with locally advanced disease, eleven evaluable patients had no evidence of disease on 18F-FDG-PET/CT at treatment end. Five-year progression-free survival and overall survival rates for all patients were 57.5% and 58.5%, respectively. CONCLUSIONS: Cetuximab with cisplatin 30 mg/m2 and radiotherapy was tolerated. 18F-FDG-PET/CT demonstrated early evidence of response to neoadjuvant cetuximab. With advances in precision oncology and the recent approval of pembrolizumab in metastatic cervical cancer, dual-target inhibition with an epidermal growth factor receptor inhibitor may be a promising treatment in the future.

Acceptability and Feasibility of Community-Based, Lay Navigator-Facilitated At-Home Self-Collection for Human Papillomavirus Testing in Underscreened Women.

Objective: Women without regular health care providers or a medical home routinely fail to complete recommended cervical cancer screening. At-home self-collection of samples to test for high-risk strains of human papillomavirus (hrHPV) can improve screening rates. This study documents acceptability and feasibility of community lay navigator (LN)-facilitated at-home self-collection for underscreened women in Appalachian Virginia. Materials and Methods: This study used mixed methods in three phases. Phase I involved focus groups of LNs to ensure cultural acceptability of self-collection, and to enhance recruitment of medically underserved women. An environmental scan of community resources and climate was created in Phase II. During Phase III, underscreened women in Appalachian Virginia (the far southwest corner of Virginia) were recruited to complete hrHPV testing using LN-provided self-collection kits. Results: LN-facilitated at-home self-collection for HPV testing was deemed culturally acceptable and feasible to participants in this community-based pilot study. Self-kit training included 64 LNs, of which 35 engaged in the study and were provided 77 kits and instructions. A total of 59 self-kits were returned, of which 42 were correctly completed with valid HPV results, yielding a 16.6% hrHPV rate. Conclusions: Over a quarter of the women LNs recruited had no medical home, indicating this delivery model may have potential to reach women at increased risk of being underscreened for cervical cancer. Research is needed to identify optimal approaches to increase LN participation in outreach self-collection interventions.

A window-of-opportunity clinical trial of dasatinib in women with newly diagnosed endometrial cancer.

OBJECTIVE: To determine the extent of dasatinib uptake and effect on Src kinase activity in tumor, normal adjacent tissue, and blood in newly diagnosed endometrial cancer patients. METHODS: Dasatinib was dosed at 100 or 200 mg PO BID at 32 and 8 h preoperatively. Blood and tissue were collected pre-treatment and at surgery to assess active (pY419) and total Src protein (pharmacodynamics [PD]) and pharmacokinetics (PK). Plasma PK and PD were also analyzed at 2, 4 and 8 h following the second dose. RESULTS: Ten patients completed the study, 5 at each dose level (DL). Average (median, standard deviation, range) 2 h plasma concentration of drug was 119 (121, 80, 226) and 236 (162, 248, 633) ng/mL, for the 100 and 200 mg DL, respectively. Average ratio of 8 h normal and tumor tissue to plasma concentration overall was 3.6 (2.3, 3.4, 9.6) and 8.3 (3.2, 11.9, 38.7), respectively. Dasatinib concentration in tumor was higher than in plasma for both DL. Four patients displayed significant reductions in pTyr419Src at ≥ 1 time points in blood, and four patients satisfied the PD activity criteria in tissue, with reductions in pTyr419Src of ≥ 60%. CONCLUSIONS: This is the first study to show PK and PD effects of dasatinib in tumor tissue, allowing evaluation of tissue PD markers as a function of tumor dasatinib concentration. Dasatinib tissue concentrations at 8 h after dosing were associated with modulation of pTyr419Src, total Src protein, and pTyr419Src/Src ratio. All patients had reduction in at least one Src parameter in either tissue or blood.
