Knowledge and Anxiety Related to Hereditary Ovarian Cancer in Serous Ovarian Cancer Patients

Implication and Influence of Multigene Panel Testing with Genetic Counseling in Korean Patients with BRCA1/2 Mutation-Negative Breast Cancer

PURPOSE

The aim of the study was to evaluate the clinical implication of multigene panel testing of beyond BRCA genes in Korean patients with BRCA1/2 mutation-negative breast cancer.

MATERIALS AND METHODS

Between 2016 and 2019, a total of 700 BRCA1/2 mutation-negative breast cancer patients received comprehensive multigene panel testing and genetic counseling. Among them, 347 patients completed a questionnaire about cancer worry, genetic knowledge, and preference for the method of genetic tests during pre- and post-genetic test counseling. The frequency of pathogenic and likely pathogenic variants (PV/LPV) were analyzed.

RESULTS

At least one PV/LPV of 26 genes was found in 76 out of 700 patients (10.9 %). The rate for PV/LPV was 3.4% for high-risk genes (17 PALB2, 6 TP53, and 1 PTEN). PV/LPVs of clinical actionable genes for breast cancer management, high-risk genes and other moderate-risk genes such as ATM, BARD1, BRIP, CHEK2, NF1, and RAD51D, were observed in 7.4%. Patients who completed the questionnaire showed decreased concerns about the risk of additional cancer development (average score, 4.21 to 3.94; p < 0.001), influence on mood (3.27 to 3.13; p < 0.001), influence on daily functioning (3.03 to 2.94; p=0.006); and increased knowledge about hereditary cancer syndrome (66.9 to 68.8; p=0.025) in post-test genetic counseling. High cancer worry scales (CWSs) were associated with age ≤ 40 years and the identification of PV/LPV. Low CWSs were related to the satisfaction of the counselee.

CONCLUSION

Comprehensive multigene panel test with genetic counseling is clinically applicable. It should be based on interpretable genetic information, consideration of potential psychological consequences, and proper preventive strategies.

Factors influencing posttraumatic growth in ovarian cancer survivors

PURPOSE

The purpose of this study was to examine posttraumatic growth (PTG), cancer coping, posttraumatic stress, and genetics knowledge among ovarian cancer survivors and to identify factors affecting PTG.

METHODS

This cross-sectional study included 148 outpatient ovarian cancer survivors at a cancer center. Data were collected between February 25 and April 11, 2019, and were analyzed using t tests, ANOVA, Pearson-correlations, and multiple regression.

RESULTS

On average, the ovarian cancer survivors scored 68.09 ± 20.17 in PTG, 59.75 ± 13.37 in cancer coping, 29.30 ± 17.25 in posttraumatic stress, and 9.42 ± 3.33 in genetics knowledge. There were significant differences in PTG according to religion (t = - 2.92, p = .004), marital status (F = 3.06, p = .050), and family history of cancer (t = 2.00, p = .047). In the final analysis, the statistically significant factors influencing PTG were religion (β = .170, p = .004) and cancer coping (β = .691, p < .001), and posttraumatic stress had borderline statistical significance (β = - .107, p < .068). These factors explained 52.2% of the variance in PTG.

CONCLUSIONS

Ovarian cancer survivors showed a moderate level of genetics knowledge while having a high risk for posttraumatic stress. Overall, this study showed that cancer coping was a powerful factor that influenced PTG in ovarian cancer survivors. Religion was found to positively affect PTG, and posttraumatic stress had a small negative effect. Spiritual nursing interventions and improving cancer coping while reducing posttraumatic stress are necessary to increase the PTG of ovarian cancer survivors.
