Abstract: Objective To assess the role of self-efficacy as a mediator of the association between patient-centred communication (PCC) and health-related quality of life (HRQoL) in a sample of participants with ovarian cancer. Methods English-speaking adults with ovarian cancer completed a cross-sectional survey. We assessed self-efficacy with the Self-Efficacy for Managing Chronic Disease scale, PCC with the Patient-Centred Communication in Cancer Care-36, and HRQoL with the Functional Assessment of Cancer Therapy-General. We used the PROCESS macro to calculate regression coefficients for the total effect of PCC on HRQoL and direct effect of PCC on HRQoL. We calculated a 95% CI for the indirect effect of PCC on HRQoL using 10 000 bootstrapped samples. Results The total effect of PCC on HRQoL (9.47, 95% CI 6.21 to 12.74) was greater than the direct effect of PCC on HRQoL (3.47, 95% CI 0.73 to 6.21). The indirect effect of PCC on HRQoL was 6.00 (95% CI 3.56 to 8.95). Self-efficacy explained approximately 63.4% of the association between PCC and HRQoL. Conclusions Self-efficacy partially mediated the association between PCC and HRQoL. Self-efficacy is a potential target for communication interventions that aim to improve HRQoL. Research to validate this finding in the setting of a randomised trial is warranted.
TL;DR: It is demonstrated that lavages capture cancer cells, even from early-stage cancers, as well as other clonal expansions and support further exploration of TP53 mutation burden as a potential OC risk factor.
Abstract: Current screening methods for ovarian cancer have failed to demonstrate a significant reduction in mortality. Uterine lavage combined with TP53 ultradeep sequencing for the detection of disseminated ovarian cancer cells has emerged as a promising tool, but this approach has not been tested for early-stage disease or non-serous histologies. In addition, lavages carry multiple background mutations, the significance of which is poorly understood. Uterine lavage was collected preoperatively in 34 patients undergoing surgery for suspected ovarian malignancy including 14 patients with benign disease and 20 patients with ovarian cancer [6 non-serous and 14 high-grade serous-like (serous)]. Ultradeep duplex sequencing (∼3,000×) with a panel of common ovarian cancer genes identified the tumor mutation in 33% of non-serous (all early stage) and 79% of serous cancers (including four early stage). In addition, all lavages carried multiple somatic mutations (average of 25 mutations per lavage), more than half of which corresponded to common cancer driver mutations. Driver mutations in KRAS, PIK3CA, PTEN, PPP2R1A, and ARID1A presented as larger clones than non-driver mutations and with similar frequency in lavages from patients with and without ovarian cancer, indicating prevalent somatic evolution in all patients. Driver TP53 mutations, however, presented as significantly larger clones and with higher frequency in lavages from individuals with ovarian cancer, suggesting that TP53-specific clonal expansions are linked to ovarian cancer development. Our results demonstrate that lavages capture cancer cells, even from early-stage cancers, as well as other clonal expansions and support further exploration of TP53 mutation burden as a potential ovarian cancer risk factor. Significance: Cancer driver mutations are found in uterine lavage DNA in all individuals, but driver TP53 mutations presented as significantly larger clones and with higher frequency in lavages from individuals with ovarian cancer. This suggests that TP53-specific clonal expansion plays a role in tumorigenesis and presents opportunities for early detection.
TL;DR: In this article , the electronic self-assessment and care (eSAC) web-based, patient reported outcome (PRO) program for people with advanced ovarian cancer was evaluated.
TL;DR: The authors found that greater perceived patient-centered communication (PCC) is associated with better health-related quality of life (HRQoL) in patients with ovarian cancer in a sequential mixed methods study.
