Effects of decisional conflict, decision regret and self-stigma on quality of life for breast cancer survivors: A cross-sectional, multisite study in China.

AIMS: To examine the differences in decisional conflict, decision regret, self-stigma and quality of life among breast cancer survivors who chose different surgeries, as well as the effects of decisional conflict, decision regret and self-stigma on quality of life. DESIGN: Observational study. METHODS: Paper and online surveys were used to collect data from March to September 2020. The Chinese version of the Decisional Conflict Scale, Decision Regret Scale, Self-Stigma Form and Functional Assessment of Cancer Treatment-B were used to measure the corresponding health outcomes for breast cancer survivors who chose different surgeries from three university-affiliated hospitals. One-way analysis of variance, Pearson's correlation coefficient and hierarchical multiple regression analysis were used for data analysis. RESULTS: Among the 448 participants, only 21% chose breast conservative surgery, while 79% chose mastectomy with or without reconstruction. Women who chose mastectomy with reconstruction reported higher decisional conflict (p = .028) and more decision regret (p = .013) than women who chose breast conservative surgery; women who chose mastectomy without reconstruction indicated higher decisional conflict (p = .015), more decision regret (p < .001), and higher self-stigma (p = .034) than women who chose breast conservative surgery. Decisional conflict (r = -.430), decision regret (r = -.495), and self-stigma (r = -.561) were negatively correlated with quality of life. After controlling for sociodemographic and clinical variables, decisional conflict and decision regret explained 19.7% and self-stigma explained 12.9% of the variance in quality of life. CONCLUSION: Decisional conflict, decision regret and self-stigma vary according to different breast surgeries and are greatly associated with the quality of life of breast cancer survivors. IMPACT: Future studies are warranted to investigate the decision-making process and the underlying reasons for surgical choices. Decision support strategies pre-surgery are needed to inform women about the risks and benefits of surgery options. Moreover, psychosocial support post-surgery is warranted to relieve women's self-stigma, thus improving their quality of life.

Carbon nanoparticle-guided central lymph node dissection in clinically node-negative patients with papillary thyroid carcinoma.

BACKGROUND: Distinguishing the involved lymph nodes from other tissues during surgery is critical for lymph node dissection. The purpose of this study was to assess the feasibility by using carbon nanoparticles as guidance for lymph node dissection in patients with papillary thyroid carcinoma (PTC). METHODS: Eighty-one patients were injected with carbon nanoparticles (carbon nanoparticle group), whereas the other 81 patients were not (control group). Routine pathological examination was performed. RESULTS: The lymph node dissection and metastatic lymph node dissection rates of the carbon nanoparticle group were significantly higher than that of the control group. In the carbon nanoparticle group, the number of mistakenly dissected parathyroid gland, the case number of postoperative hypocalcemia, the case number of postoperative hypoparathyroidism, and the recovery time from hypocalcemia were 4, 6, 8, and 2.33 ± 0.58 weeks, respectively, significantly less than 14, 17, 20, 3, and 3.8 ± 0.92 weeks in the control group (p < .05). CONCLUSION: Carbon nanoparticles can be applied to more accurately guide the dissection of lymph nodes during thyroidectomy in patients with PTC. © 2015 Wiley Periodicals, Inc.
