Background: The consequence of diabetes on lung cancer overall survival (OS) is debated. This retrospective study used 2 large lung cancer databases to assess comprehensively diabetes effects on lung cancer OS in diverse demographic populations, including health disparity.

Methods: The University of Texas MD Anderson Cancer Center database (32 643 lung cancer patients with 11 973 patients with diabetes) was extracted from electronic health records (EHRs) using natural language processing (NLP). Associations were between diabetes and lung cancer prognostic features (age, sex, race, body mass index [BMI], insurance status, smoking, stage, and histopathology). Hemoglobin A1C (HgbA1c) and glucose levels assessed glycemic control. Validation was with a Louisiana cohort (17 768 lung cancer patients with 5402 patients with diabetes) enriched for health disparity cases. Kaplan-Meier analysis, log-rank test, multivariable Cox proportional hazard models, and survival tree analyses were employed.

Results: Lung cancer patients with diabetes exhibited marginally elevated OS or no statistically significant difference versus nondiabetic patients. When examining OS for 2 glycemic levels (HgbA1c > 7.0 or glucose > 154 mg/dL vs HgbA1c > 9.0 or glucose > 215 mg/dL), a statistically significant improvement in OS occurred in lung cancer patients with controlled versus uncontrolled glycemia (P < .0001). This improvement spanned sex, age, smoking status, insurance status, stage, race, BMI, histopathology, and therapy. Survival tree analysis revealed that obese and morbidly obese patients with controlled glycemia had higher lung cancer OS than comparison groups.

Conclusion: These findings indicate a need for optimal glycemic control to improve lung cancer OS in diverse populations with diabetes.

Background: Cyclin-dependent kinases (CDK) 4/6 inhibitors have significantly improved outcomes for patients with ER+/HER2- breast cancer. Nevertheless, they differ from each other in terms of chemical, biological, and pharmacological features, as well as toxicity profiles. We aim to determine whether QTc prolongation is caused by CDK4/6i in general or if it is associated with ribociclib only.

Methods: We systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs) comparing the prevalence of QTc prolongation as an adverse event in HR+ breast cancer patients treated with CDK4/6i vs those without CDK4/6i. We pooled relative risk (RR) and mean difference (MD) with 95% confidence interval (CI) for the binary endpoint of QT prolongation.

Results: We included 14 RCTs comprising 16 196 patients, of whom 8576 underwent therapy with CDK4/6i. An increased risk of QTc prolongation was associated with the use of CDK4/6i (RR = 2.35, 95% CI = 1.67 to 3.29, P < .001; I2 = 44%). Subgroup analyses revealed a significant increase in the QTc interval for the ribociclib and palbociclib cohorts. The ribociclib subgroup showed a relative risk of 3.12 (95% CI = 2.09 to 4.65, P < .001; I2 = 12%), whereas the palbociclib subgroup had a relative risk of 1.51 (95% CI = 1.05 to 2.15, P = .025; I2 = 0%).

Conclusion: Palbociclib was associated with QTc prolongation; however, the relative risk for any grade QTc was quantitively twice with ribociclib. Furthermore, grade 3 QTc prolongations were observed exclusively with ribociclib. These results are important for guiding clinical decision-making and provide reassurance regarding the overall safety profile of this drug class.

Background: The long-term financial impact of cancer care has not been adequately addressed in young adults. As part of a remote intervention study, we describe medical financial distress and hardship among young adult survivors of blood cancer at study entry.

Methods: Young adults were recruited from 6 US hospitals. Using a Research Electronic Data Capture link, young adults confirmed their eligibility-namely, currently 18 to 39 years of age, blood cancer diagnosis 3 or more years ago, off active treatment, and not on parent's insurance. Following consent, the baseline assessment was sent. The primary outcome measure, the Personal Financial Wellness Scale, measured financial distress (scored as severe, 1-2; high, 3-4; average, 5-6; and low to no, 7-10). Medical financial hardship encompassed material hardship, psychological impact, and coping behaviors. Descriptive summary statistics and linear regression were used.

Results: Among the 126 participants, 54.5% came from minority racial or ethnic groups. Median time since diagnosis was 10 years (interquartile range = 6-16 years), with 56% having received a diagnosis when they were between 18 and 39 years of age. The overall mean (standard deviation) Personal Financial Wellness Scale score was 5.1 (2.4), but 49% reported severe or high distress. In multivariable analysis, female sex, Hispanic ethnicity, and lower income were strongly associated with worse Personal Financial Wellness Scale scores. Among participants with severe financial distress (n = 26), 72% reported 2 or more household material hardships, had worse scores across all psychological domains, and altered survivorship care because of cost (68%).

Conclusions: Nearly half of long-term young adult cancer survivors reported severe or high levels of financial distress. Individuals with severe or high distress also reported more medical financial hardship than other participants. This finding highlights the need for ongoing financial intervention in this vulnerable population.

Clinicaltrials.gov: NCT05620979.

The majority of tumor comprehensive genomic profiling (CGP) currently does not include a matched normal control. The use of a tumor-only CGP approach needs the development of a strategy to refine germline pathogenic/likely pathogenic variants (gP/LPVs) calls, so as to limit the performance of unnecessary germline reflex tests and instead successfully identify patients who are carriers of likely gP/LPVs. Guidelines have been developed for the identification of gP/LPVs in BRCA1/2 genes on the basis of tumor-only CGP results and for the evaluation of the appropriateness of performing germline reflex BRCA1/2 testing. In this study, an algorithm to assist decision-making for germline reflex testing of BRCA1/2 variants following tumor-only CGP is proposed.

Background: Men with prostate cancer (PC) may experience significant psychosocial distress from physical symptoms, treatment side effects, or fear of recurrence. However, little is known about the long-term risk of anxiety disorders in men with PC.

Methods: A national cohort study was conducted of 180 189 men diagnosed with PC during 1998-2017 and 1 801 890 age-matched population-based control men in Sweden. Anxiety disorders were ascertained from nationwide outpatient and inpatient records through 2018. Cox regression was used to estimate hazard ratios (HRs) while adjusting for sociodemographic factors and prior psychiatric disorders. Subanalyses explored differences by PC treatment during 2005-2017.

Results: In 7.8 million person-years of follow-up, 94 387 (5%) men were diagnosed with anxiety disorders. Men with high-risk PC had a nearly 2-fold higher risk of anxiety disorders than control men without PC (adjusted HR = 1.96, 95% CI = 1.87 to 2.05). This risk was highest in the first 3 months after PC diagnosis (adjusted HR = 2.99, 95% CI = 2.49 to 3.59) but remained significantly elevated 10 or more years later (adjusted HR = 1.53, 95% CI = 1.35 to 1.74). Those treated only with androgen deprivation therapy (ADT) had the highest risk of anxiety disorders (adjusted HR = 2.08, 95% CI = 1.93 to 2.25). Men with low- or intermediate-risk PC had a modestly increased risk (adjusted HR = 1.39, 95% CI = 1.34 to 1.44).

Conclusions: In this large national cohort, men with PC had substantially increased risk of anxiety disorders, especially those with high-risk PC and treated only with ADT. Men with PC need close monitoring for timely detection and treatment of anxiety symptoms, particularly shortly after PC diagnosis.

Background: In addition to greater delays in cancer screening and greater financial hardship, rural-dwelling cancer patients experience greater costs associated with accessing cancer care, including higher cumulative travel costs. This study aimed to identify and synthesize peer-reviewed research on the cumulative and overlapping costs associated with care access and utilization.

Methods: A scoping review was conducted to identify relevant studies published after 1995 by searching 5 electronic databases: PubMed, Scopus, Cumulative Index of Nursing and Allied Health Literature (CINAHL), PsycInfo, and Healthcare Administration. Eligibility was determined using the PEO (Population, Exposure, and Outcomes) method, with clearly defined populations (cancer patients), exposures (financial hardship, toxicity, or distress; travel-related burdens), and outcomes (treatment access, treatment outcomes, health-related quality of life, and survival/mortality). Study characteristics, methods, and findings were extracted and summarized.

Results: Database searches yielded 6439 results, of which 3366 were unique citations. Of those, 141 were eligible for full-text review, and 98 studies at the intersection of cancer-related travel burdens and financial hardship were included. Five themes emerged as we extracted from the full texts of the included articles: 1) Cancer treatment choices, 2) Receipt of guideline-concordant care, 3) Cancer treatment outcomes, 4) Health-related quality of life, and 5) Propensity to participate in clinical trials.

Conclusions: This scoping review identifies and summarizes available research at the intersection of cancer care-related travel burdens and financial hardship. This review will inform the development of future interventions aimed at reducing the negative effects of cancer-care related costs on patient outcomes and quality of life.

Background: Sigmoid colon cancer is a common type of colorectal cancer, frequently leading to liver metastasis. Predicting cause-specific survival and overall survival in patients with sigmoid colon cancer metastasis to liver is challenging because of the lack of suitable models.

Methods: Patients with sigmoid colon cancer metastasis to liver (2010-2017) in the Surveillance, Epidemiology, and End Results (SEER) Program were recruited. Patients were split into training and validation groups (7:3). Prognostic factors were identified using competing risk and Cox proportional hazards models, and nomograms for cause-specific survival and overall survival were developed. Model performance was evaluated with the concordance index and calibration curves, with a 2-sided P value less than .05 considered statistically significant.

Results: A total of 4981 sigmoid colon cancer with liver metastasis patients were included, with a median follow-up of 20 months (interquartile range [IQR] = 9-33 months). During follow-up, 72.25% of patients died (68.44% from sigmoid colon cancer, 3.81% from other causes). Age, race, grade, T stage, N stage, surgery, chemotherapy, carcinoembryonic antigen, tumor deposits, lung metastasis, and tumor size were prognostic factors for cause-specific survival and overall survival. The models demonstrated good discrimination and calibration performance, with C index values of 0.79 (95% confidence interval [CI] = 0.78 to 0.80) for cause-specific survival and 0.74 (95% CI = 0.73 to 0.75) for overall survival. A web-based application for real-time cause-specific survival predictions was created, accessible at https://shuaishao.shinyapps.io/SCCLM/.

Conclusion: Prognostic factors for sigmoid colon cancer with liver metastasis patients were identified based on the SEER database, and nomograms for cause-specific survival and overall survival showed good performance. A web-based application was developed to predict sigmoid colon cancer with liver metastasis-specific survival, aiding in survival risk stratification.
