Research on the Role of Marriage Status Among Women Underwent Breast Reconstruction Following Mastectomy: A Competing Risk Analysis Model Based on the SEER Database, 1998–2015

Social support, social constraint, and psychological adjustment in patients with colorectal cancer

Cancer patients' social networks, particularly their spouses or romantic partners, can promote or undermine their psychological adjustment. This study examined the relative associations of partner social support and social constraint with patients' psychological adjustment and further tested gender's moderating role in these associations. Participants were 124 patients newly diagnosed with colorectal cancer (M age = 56.6 years, 34% female), who completed questionnaires on perceived spousal social support and social constraint, depressive symptoms, and life satisfaction. Findings revealed that greater social constraint was significantly associated with lower life satisfaction regardless of gender; however, greater social constraint was only associated with greater depressive symptoms in male patients. No significant associations or interactions with social support were found. Findings highlight the importance for patients-especially male patients-with cancer to feel able to disclose cancer-related thoughts and feelings to their partners and call for more consistent operationalization and measurement when studying patients' social functioning.

Factors associated with declining cytoreductive surgery in advanced epithelial ovarian cancer: a population-based study

OBJECTIVE

Cytoreductive surgery serves as a cornerstone intervention for advanced epithelial ovarian cancer (EOC), yet some patients decline the procedure despite clinical recommendations. This study aimed to evaluate survival outcomes and identify sociodemographic and clinical factors associated with this decision in advanced EOC patients.

METHODS

A retrospective analysis of EOC cases from the Surveillance, Epidemiology, and End Results (SEER) database (2004-2021) was conducted, including patients with stage III/IV EOC recommended for surgery. Patients were categorized into surgical and non-surgical cohorts. Propensity Score Matching (PSM) was applied to adjust for baseline differences, and survival outcomes were compared using Kaplan-Meier and Cox proportional hazards models. Logistic regression analysis was performed to identify predictors of surgery declination.

RESULTS

Of the 21,988 patients included, 363 (1.7%) were in the non-surgery group. Following a median follow-up of 33 months, patients in the non-surgical cohort demonstrated significantly lower overall survival (OS) compared to the surgical cohort, with mean OS of 17.8 months versus 45.8 months, respectively (P < 0.001). The Cox model showed increased mortality risk for the non-surgical group post-PSM (HR, 1.87; 95% CI, 1.62-2.15). Non-Hispanic Black, older age, lower household income, nonmetropolitan residence, and unmarried status were associated with higher odds of surgery refusal.

CONCLUSION

Declining surgery is associated with significantly poorer survival in advanced EOC. Sociodemographic factors play a key role in surgical decision-making, underscoring the need for targeted interventions to improve access to surgical care and reduce disparities in EOC treatment outcomes. Further studies should explore the impact of specific chemotherapy and comorbidities on surgery refusal and survival.

Barriers to radiotherapy completion in breast cancer patients: A retrospective analysis from a tertiary hospital in Indonesia

INTRODUCTION

Breast cancer is the most common malignancy among women and a leading cause of cancer-related mortality in Indonesia. Radiotherapy is a crucial treatment modality to improve local control, reduce recurrence, and enhance survival rates. However, access to radiotherapy remains limited, leading to prolonged waiting times and potential treatment incompletion. This study aims to identify key predictors influencing radiotherapy completion and analyze waiting times in a resource-limited setting METHODS: A retrospective study was conducted on breast cancer patients who underwent radiotherapy between January 2018 and December 2019 at Hasan Sadikin General Hospital, Indonesia. Data were obtained from the Hospital-Based Cancer Registry (HBCR). Statistical analyses were performed using chi-square and Mann-Whitney U tests to assess factors influencing radiotherapy completion and waiting time.

RESULTS

279 Breast cancer patients were included. 77.8 % (n = 217) completed their prescribed radiotherapy. Significant predictors of completion include age, those older than 65 years old tend to do not complete their radiation treatment (p = 0.035). Those receiving treated using Linac radiotherapy had higher completion rates than those treated with Co-60. However, waiting time was not significantly associated with treatment completion (p = 0.427). The median radiotherapy waiting time was 8 weeks (0-40 weeks). Patients with metastatic disease (p < 0.001) and those receiving palliative intent radiotherapy (p < 0.001) experienced significantly shorter waiting times.

CONCLUSION

Radiotherapy completion rates among breast cancer patients in Indonesia remain suboptimal, with access disparities affecting treatment adherence. Addressing logistical and systemic barriers could improve outcomes and enhance cancer care delivery in resource-limited settings.

PLAIN LANGUAGE SUMMARY

Breast cancer is the most common cancer among women in Indonesia. Many patients require radiotherapy to prevent the disease from coming back and to improve survival. However, some patients do not complete their treatment due to long waiting times and other challenges. This study looks at how long patients wait for radiotherapy and what factors influence whether they complete treatment. We analyzed the medical records of 279 breast cancer patients who received radiotherapy at Hasan Sadikin General Hospital between 2018 and 2019. We examined their age, radiation therapy tools, waiting time, and whether they completed radiotherapy. We used statistical methods to find patterns and associations between these factors. Our findings suggest that certain groups of patients, especially older individuals and those undergoing curative treatment, may need additional support to complete their radiotherapy.

Effect of marital status on the survival outcomes of cervical cancer: a retrospective cohort study based on SEER database

BACKGROUND

Cervical cancer is the fourth most common malignant tumor troubling women worldwide. Whether marital status affects the prognosis of cervical cancer is still unclear. Here, we investigate the prognostic value of marital status in patients with cervical cancer based on the seer database.

MATERIAL/METHODS

The demographic and clinical data of patients with cervical cancer were extracted from the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2017. Patients were divided into two groups (married and unmarried) according to marital status, and then the clinical characteristics of each group were compared using the chi-square test. Propensity score matching (PSM) was used to reduce differences in baseline characteristics. The overall survival (OS) and cervical cancer-specific survival (CCSS) were assessed by the Kaplan-Meier method, univariate and multivariate Cox regression models, and stratified analysis. Moreover, univariate and multivariate competing risk regression models were performed to calculate hazard ratios (HR) of death risk.

RESULTS

A total of 21,148 patients were included in this study, including 10,603 married patients and 10,545 unmarried patients. Married patients had better OS(P < 0.05) and CCSS (P < 0.05) compared to unmarried patients, and marital status was an independent prognostic factor for both OS (HR: 0.830, 95% CI: 0.798-0.862) and CCSS (HR: 0.892, 95% CI: 0.850-0.937). Moreover, after eliminating the competing risk, married patients (CCSD: HR:0.723, 95% CI: 0.683-0.765, P < 0.001) had a significantly decreased risk of death compared to unmarried patients. In stratified analysis, the married patients showed better OS and CCSS than the unmarried patients diagnosed in 1975-2000 and 2001-2017.

CONCLUSIONS

Being married was associated with a favorable prognosis of cervical cancer, and marital status was an independent prognostic factor for cervical cancer.

Exploring the geospatial epidemiology of breast cancer in Iran: identifying significant risk factors and spatial patterns for evidence-based prevention strategies

BACKGROUND

Breast Cancer (BC) is a formidable global health challenge, and Iran is no exception, with BC accounting for a significant proportion of women's malignancies. To gain deeper insights into the epidemiological characteristics of BC in Iran, this study employs advanced geospatial techniques and feature selection methods to identify significant risk factors and spatial patterns associated with BC incidence.

METHODS

Using rigorous statistical methods, geospatial data from Iran, including cancer-related, sociodemographic, healthcare infrastructure, environmental, and air quality data at the provincial level, were meticulously analyzed. Age-standardized incidence rates (ASR) are calculated, and different regression models are used to identify significant variables associated with BC incidence. Spatial analysis techniques, including global and local Moran's index, geographically weighted regression, and Emerging hotspot analysis, were utilized to examine geospatial patterns, identify clustering and hotspots, and assess spatiotemporal distribution of BC incidence.

RESULTS

The findings reveal that BC predominantly affects women (98.03%), with higher incidence rates among those aged 50 to 79. Isfahan (ASR = 26.1) and Yazd (ASR = 25.7) exhibit the highest rates. Significant predictors of BC incidence, such as marriage, tertiary education attainment rate, physician-to-population ratio, and PM2.5 air pollution, are identified through regression models.

CONCLUSION

The study's results provide valuable information for the development of evidence-based prevention strategies to reduce the burden of BC in Iran. The findings underscore the importance of early detection, health education campaigns, and targeted interventions in high-risk clusters and adjacent regions. The geospatial insights generated by this study have implications for policy-makers, researchers, and public health practitioners, facilitating the formulation of effective BC prevention strategies tailored to the unique epidemiological patterns in Iran.

Marital Status Is a Prognostic Factor for Cardiovascular Mortality but Not a Prognostic Factor for Cancer Mortality in Siewert Type II Adenocarcinoma of the Esophagogastric Junction

Background

The impact of marital status on the prognosis of patients with Siewert type II adenocarcinoma of the esophagogatric junction (AEG) remained unclear. This study aimed to investigate the associations of marital status with cancer-specific death risk and cardiovascular death risk in Siewert type II AEG patients.

Methods

Data for Siewert type II AEG patients were obtained from the Surveillance, Epidemiology, and End Results database from 2010 to 2015. A 1:1 propensity score matching (PSM) was applied to reduce inter-group bias between the married and unmarried groups. Kaplan-Meier analysis, a competing risk model and the Fine-Gray multivariable regression model were used to identify the prognostic value of marital status.

Results

In total, 1,623 subjects were included. After PSM, according to Fine-Gray multivariable regression analysis, there was no significant difference in the cumulative cancer-specific death rate between the married and the unmarried groups (hazard ratio (HR): 1.160, 95% confidence interval (CI): 0.994 - 1.354, P = 0.060). Patients in unmarried group had a higher cardiovascular death rate than patients in married group (HR: 3.066, 95% CI: 1.372 - 6.850, P = 0.006).

Conclusions

Our study demonstrates that unmarried Siewert type II AEG patients are associated with higher cardiovascular death risk but not cancer-specific death risk compared with married patients.
