Decision-making under clinical uncertainty: An in-depth examination of provider perspectives on adjuvant chemotherapy for stage II colon cancer.

ABSTRACT: OBJECTIVE:Decision-making about adjuvant chemotherapy (ACT) for stage II colon cancer is complex, particularly in light of clinical uncertainty regarding treatment benefits. Little is known about provider communication and factors influencing decision-making and recommendations in this setting. METHODS:We recruited providers from six US cancer centers and hospitals who care for stage II colon cancer patients. Providers participated in a 30-45?minute interview. Transcripts of interviews were coded for qualitative analysis. RESULTS:We interviewed 42 providers (Oncologists: 52%; surgeons: 24%; nurses: 14%). Though most providers were aware of stage II colon cancer treatment guidelines, their use and communication of recommended guidelines was limited. Most reported tailoring delivery and content of their communication, often based on perceived patient education level, but patient involvement in decision-making varied. Findings highlight the complexity of, ACT decision-making, including the central role of providers and family members. CONCLUSIONS:Providers are not consistently following recommended guidelines for communicating about ACT among stage II colon cancer patients or eliciting patient preferences for involvement in treatment decisions. PRACTICE IMPLICATIONS:Given clinical uncertainty surrounding use of ACT for stage II colon cancer, efforts are needed to enhance guideline implementation, provider education, and communication to facilitate decision-making.

Project description:Background. To explore preferred and actual involvement in chemotherapy decision making among stage II and III colon cancer (CC) patients by sociodemographic, interpersonal, and intrapersonal communication factors. Methods. Cross-sectional exploratory study collecting self-reported survey data from stage II and III CC patients from 2 cancer centers located in northern Manhattan. Results. Of 88 patients approached, 56 completed the survey. Only 19.3% reported shared involvement in their chemotherapy decisions. We observed significant differences in preferred involvement by gender, with women preferring more physician-controlled decisions. CC patients with higher levels of decisional self-efficacy significantly preferred shared decisions (F = 4.4 [2], P = 0.02). Actual involvement in decisions differed by race (physician controlled 33% for White v. 67% for Other, P < 0.01), age (shared control 18% for ≤55 y, 55% for 55-64 y, and 27% for 65+ y, P = 0.04), and perception of choice (shared control 73% "yes" v. 27% "no,"P = 0.02). Actual or preferred involvement did not differ by stage. Significantly higher levels of medical mistrust (discrimination t = 2.8 [50], P = 0.01; lack of support t = 3.6 [49], P < 0.01), and lower levels of decisional self-efficacy (t = 2.5 [49], P = 0.01) were reported among women. Discussion. Reports of shared involvement around chemotherapy decisions is limited among CC patients. Factors influencing preferred versus actual chemotherapy decision making are complex and may differ; hence, more research is needed to understand and address factors contributing to discordance between preferred and actual involvement in chemotherapy decision making for CC patients.HighlightsShared involvement around chemotherapy decisions remains limited for patients diagnosed with colon cancer.Sociodemographic (age, race, gender), interpersonal (medical mistrust), and intrapersonal (decisional self-efficacy, perception of choice) factors that influence preferred involvement in chemotherapy decision making may differ from those influencing actual involvement in chemotherapy decision making.Shared involvement in chemotherapy decisions may look different than currently conceptualized, notably when uncertainty around the benefits exists.

Project description:Background: Most patients with early gastric cancer (EGC) can achieve a better 5-year survival rate after endoscopic resection or surgery. However, indications for adjuvant chemotherapy (ACT) after surgery have not yet been determined. Methods: A total of 4,108 patients with EGC diagnosed in 2004-2016 were retrospectively analyzed using the Surveillance, Epidemiology, and End Results (SEER) database. Of these, 3,521 patients received postoperative ACT and 587 patients did not. Propensity score matching was used to balance the two groups' confounding factors. Kaplan-Meier method was utilized to perform survival analysis. Log-rank test was used to compare the differences between survival curves. Cox proportional-hazards regression model was used to screen independent risk factors and build a nomogram for the non-ACT group. The X-tile software was employed to artificially divide all patients into low-, moderate-, and high-risk groups according to the overall survival score prediction based on the nomogram. A total of 493 patients with EGC diagnosed between 2010 and 2014 in our hospital were included for external validation. Results: Multivariate analysis found that age, sex, race, marital status, primary site, surgical extent, and metastatic lymph node ratio in the non-ACT group were independent prognostic factors for EGC and were included in the construction of the nomogram. The model C-index was 0.730 (95% confidence interval: 0.677-0.783). The patients were divided into three different risk groups based on the nomogram prediction score. Patients in the low-risk group did not benefit from ACT, while patients in the moderate- and high-risk groups did. External validation also demonstrated that moderate- and high-risk patients benefited from ACT. Conclusion: The study nomogram can effectively evaluate postoperative prognosis of patients with EGC. Postoperative ACT is therefore recommended for moderate- and high-risk patients, but not for low-risk patients.
