"I think that a brief conversation from their provider can go a very long way": Patient and provider perspectives on barriers and facilitators of genetic testing after ovarian cancer

OBJECTIVE

Identify predisposing, enabling, and reinforcing factors impacting genetic counseling/testing among ovarian cancer patients guided by Green and Kreuter's PRECEDE-PROCEED model.

METHODS

Gynecologic oncology providers (N = 4), genetic counselors (N = 4), and ovarian cancer patients (N = 9) completed semi-structured qualitative interviews exploring participants' knowledge of and experiences with genetic counseling/testing. Interviews were audio recorded, transcribed verbatim, and analyzed using inductive content analysis by two independent raters.

RESULTS

Thematic analysis identified predisposing, enabling, and reinforcing factors impacting referral for and uptake of genetic counseling/testing. Predisposing factors included participant's knowledge, beliefs, and attitudes related to genetic counseling/testing. Both patients and providers also cited that insurance coverage and out-of-pocket cost are major concerns for ovarian cancer patients considering genetic testing. Finally, both patients and providers emphasized that genetic counseling/testing would provide additional information to an ovarian cancer patient. While providers emphasized that genetic testing results were useful for informing a patient's personal treatment plan, patients emphasized that this knowledge would be beneficial for their family members.

CONCLUSION

Barriers to genetic testing for ovarian cancer patients exist at multiple levels, including the patient (e.g., knowledge, attitudes), the provider (e.g., workload, availability of services), the institution (e.g., difficulty with referrals/scheduling), and the healthcare system (e.g., insurance/cost). Interventions aiming to increase genetic testing among ovarian cancer patients will likely need to target multiple levels of influence. Future quantitative studies are needed to replicate these results. This line of work will inform specific multilevel intervention strategies that are adaptable to different practice settings, ultimately improving guideline concordant care.

Patterns and covariates of benefit finding in young Black breast cancer survivors: A longitudinal, observational study

OBJECTIVE

To examine the patterns and covariates of benefit finding over time among young Black breast cancer (BC) survivors.

METHODS

Black women (N = 305) with invasive BC diagnosed ≤50 years were recruited an average of 1.9 years post-BC diagnosis. Participants completed self-report questionnaires of benefit finding, social support, and illness intrusions at three time points (M time since BC diagnosis: T2 = 3.1 years, T3 = 4.0 years). Relationships between posttraumatic growth constructs (social support, illness intrusions) and benefit finding over time were examined using mixed models. Models controlled for cultural variables (religiosity, time orientation, and collectivism), receipt of chemotherapy, general health status, and partner status.

RESULTS

Participants reported high levels of benefit finding (M = 2.99, SE = 0.04 on a 0-4 scale). When accounting for covariates, benefit finding did not change over time since BC diagnosis (P = .21). Benefit finding scores at BC diagnosis were associated with more illness intrusions, greater religiosity, and having received chemotherapy (all Ps < .04). Social support was associated with change in benefit finding scores over time, such that a 1-point increase in social support was associated with a 0.05 increase in benefit finding per year (P = .02).

CONCLUSIONS

This study addresses key gaps in knowledge regarding benefit finding among Black cancer survivors. Consistent with findings from majority White samples, social support and illness intrusions appear to play a key role in benefit finding in Black BC survivors. Cultural constructs-including religiosity-must also be considered in future studies of benefit finding among minority populations.

Patterns and predictors of genetic referral among ovarian cancer patients at a National Cancer Institute-Comprehensive Cancer Center

Germline mutations (eg, BRCA1/2) have prognostic and treatment implications for ovarian cancer (OVCA) patients. Thus, national guidelines recommend genetic testing for OVCA patients. The present study examines patterns and predictors of genetics referral in OVCA patients. Electronic medical record data were abstracted retrospectively from 557 OVCA patients treated from 1 January 2001 to 31 December 2015. Logistic regression models identified sociodemographic characteristics, disease/treatment characteristics, family history data, provider characteristics, and survival data that predicted genetics referral. Overall, 27.5% of patients received referral. Eleven variables predicting referral were selected during stepwise regression: younger age, White race, not having private insurance, professional school education, year of OVCA diagnosis, platinum sensitivity, female gynecologic oncologist, chemotherapy administered by a gynecologic oncologist, clinical trial enrollment, longer overall survival, and family history of OVCA. Genetics referral among OVCA patients was similar to rates reported nationwide. Unique predictive factors will contribute to quality improvement and should be validated at a multi-institutional level to ensure guideline concordant care is provided to all OVCA patients. Future research should identify both patient-level and provider-level factors associated with genetics referral.

Impact of Genetic Testing on Risk-Management Behavior of Black Breast Cancer Survivors: A Longitudinal, Observational Study

BACKGROUND

Black women are overrepresented among premenopausal breast cancer (BC) survivors. These patients warrant genetic testing (GT) followed by risk-reducing behaviors. This study documented patterns and predictors of cancer risk-management behaviors among young black BC survivors after GT.

METHODS

Black women (n = 143) with a diagnosis of BC at the age of 50 years or younger received GT. At 1 year after GT, participants reported receipt of risk-reducing mastectomy, risk-reducing salpingo-oophorectomy, mammogram, breast magnetic resonance imaging (MRI), CA125 test, and transvaginal/pelvic ultrasound. Logistic regression was used to examine predictors of BC risk management (risk-reducing mastectomy or breast MRI) and ovarian cancer risk management (risk-reducing salpingo-oophorectomy, CA125 test, or transvaginal/pelvic ultrasound).

RESULTS

Of the study participants, 16 (11%) were BRCA1/2-positive, 43 (30%) had a variant of uncertain significance, and 84 (59%) were negative. During the 12 months after GT, no women received risk-reducing mastectomy. The majority (93%) received a mammogram, and a smaller proportion received breast MRI (33%), risk-reducing salpingo-oophorectomy (10%), CA125 test (11%), or transvaginal/pelvic ultrasound (34%). Longer time since the BC diagnosis predicted lower likelihood of BC risk management (odds ratio [OR] 0.54). BRCA1/2 carrier status (OR 4.57), greater perceived risk of recurrence (OR 8.03), and more hereditary breast and ovarian cancer knowledge (OR 1.37) predicted greater likelihood of ovarian cancer risk management.

CONCLUSIONS

Young black BC survivors appropriately received mammograms and ovarian cancer risk management based on their BRCA1/2 test result. However, the low usage of MRI among BRCA1/2 carriers contrasts with national guidelines. Future research should examine barriers to MRI among black BC survivors. Finally, modifiable variables predicting risk management after GT were identified, providing implications for future interventions.
