Socioeconomic Status-Related Parameters as Predictors of Competing (Non-Bladder Cancer) Mortality after Radical Cystectomy

Socioeconomic disparities between oral cavity cancer patients in Germany

Objective

In many countries the access to high quality medical service depends on socioeconomic factors. Therefore, these factors are associated with the treatment and prognosis of many diseases. In Germany health care is claimed to be independent from such factors due to obligatory health insurance and a well-developed medical infrastructure. Thus, socioeconomically caused health disparities should be absent. The aim of this study was to analyze the association between socioeconomic factors and the survival of oral cavity cancer in Germany.

Patients and methods

In this descriptive cohort study socioeconomic status related factors as well as demographic, tumor-specific, and comorbidity factors of 500 patients treated for oral cavity cancer were obtained in the university hospital of Dresden. Pearson correlation was used to describe associations between continuous variables. Associations between categorical variables were assessed using the chi-square test. Overall and recurrence-free survival were studied using the Kaplan-Meier method. Log-rank test was carried out to test between-group differences. Cox proportional hazard models were used to estimate the risk of death and the risk of recurrence.

Results

Significant differences in overall survival were found between the different educational levels and sex. Seventy-nine percent of the patients did not have a university degree or master craftsman/craftswoman. Less discrepancy was observed according to the marital status (49.4% married/engaged vs. 47.8% single, divorced, or widowed). In the multivariable analysis only sex, age at diagnosis, the Charlson score, the number of positive lymph nodes, and the nodal status were identified as independent predictors for overall survival whereas sex and the age at diagnosis were identified as independent predictors for recurrence-free survival.

Conclusion

Despite the equitable health system in Germany, significant associations between overall survival of oral cavity cancer and different socioeconomic factors could be found. For elimination of these disparities, health education programs should be established in socially deprived areas. Furthermore, clinicians should keep these factors in mind when determining recall periods for dental check-ups.

Smoking and bladder cancer: review of the recent literature

PURPOSE OF REVIEW

This review summarizes the current knowledge regarding the relationship between smoking and bladder cancer (BCa), especially with respect to treatment outcomes for muscle and nonmuscle-invasive BCa (MIBC/NMIBC).

RECENT FINDINGS

PubMed/Medline databases were searched for recent reports investigating the association of smoking with BCa. Smoking is associated with an increased risk of recurrence in patients with NMIBC and may impair Bacillus Calmette-Guerin treatment efficacy. Moreover, smoking is associated with poor responses to neoadjuvant chemotherapy, poor survival outcomes and high complication rates in patients undergoing radical cystectomy. Smoking cessation mitigates these negative effects, especially. However, the amount of patient counselling provided regarding this important matter and patient knowledge regarding smoking and BCa risk are inadequate. Currently, the impact of secondhand smoke on BCa risk remains uncertain.

SUMMARY

Tobacco smoking is responsible for approximately half of BCa cases, and is associated with poor oncological outcomes for both NMIBC and MIBC. Despite smoking being a well known risk factor, counselling and knowledge in this area are insufficient. Appropriate smoking cessation interventions and patient information are required to improve patient health and optimize BCa survival.

Perioperative Mortality and Long-Term Survival after Radical Cystectomy: A Population-Based Study in a Southern European Country on 4,389 Patients

PURPOSE

Population-based data on survival after radical cystectomy (RC) are lacking from Southern Europe. The aim of this study was to assess trends and determinants of perioperative mortality and long-term survival in the Veneto region (Northeastern Italy).

METHODS

All patients submitted to RC for bladder cancer from January 2004 to December 2016 were identified from the regional archive of hospital discharge records. Age at surgery, gender, comorbidities, hospital volume, calendar period of surgery, and type of urinary diversion were retrieved; vital status and cause of death were obtained by linkage with mortality records. Determinants of 90-day mortality were assessed by multilevel logistic regression; long-term survival was investigated by the Kaplan-Meier method and Cox regression.

RESULTS

Among 4,389 included patients, an increase in the share of patients aged ≥80 years (from 13% in 2004-2008 to 24% in 2013-2016, p < 0.001) and a decline in performing continent diversion (from 34.9 to 23.4%, p < 0.001) were observed across the study period. Ninety-day mortality did not change over time and was 4% for patients aged <70 years and 13.7% for those aged ≥80 years. Age- and comorbidities-adjusted mortality was significantly lower in hospitals performing >30 RCs/year (odds ratio 0.67, 95% confidence interval 0.48-0.93). At a median follow-up of 67 months, overall survival at 1 year and 5 years was 72 and 40%, respectively, with a higher rate among younger patients treated in high-volume hospitals.

CONCLUSION

The population of patients treated with RC is rapidly ageing, with a high risk of perioperative and long-term mortality; this changing epidemiological scenario and better outcomes observed in high-volume hospitals support regionalization of the procedure.
