Marital status and survival after oesophageal cancer surgery: a population-based nationwide cohort study in Sweden.

ABSTRACT:

Objectives

A beneficial effect of being married on survival has been shown for several cancer types, but is unclear for oesophageal cancer. The objective of this study was to clarify the potential influence of the marital status on the overall and disease-specific survival after curatively intended treatment of oesophageal cancer using a nationwide population-based design, taking into account the known major prognostic variables.

Design

Prospective, population-based cohort.

Setting

All Swedish hospitals performing surgery for oesophageal cancer during 2001-2005.

Participants

This study included 90% of all patients with oesophageal or junctional cancer who underwent surgical resection in Sweden in 2001-2005, with follow-up until death or the end of the study period (2012).

Primary and secondary outcome measures

Cox regression was used to estimate associations between the marital status and the 5-year overall and disease-specific mortality, expressed as HRs with 95% CIs, with adjustment for sex, age, tumour stage, histological type, complications, comorbidities and annual surgeon volume.

Results

Of all 606 included patients (80.4% men), 55.1% were married, 9.2% were remarried, 22.6% were previously married and 13% were never married. Compared with the married patients, the never married (HR 1.02, 95% CI 0.77 to 1.35), previously married (HR 0.90, 95% CI 0.71 to 1.15) and remarried patients (HR 0.79, 95% CI 0.55 to 1.13) had no increased overall 5-year mortality. The corresponding HRs for disease-specific survival, and after excluding the initial 90?days of surgery, were similar to the HRs for the overall survival.

Conclusions

This study showed no evidence of a better 5-year survival in married patients compared with non-married patients undergoing surgery for oesophageal cancer.

Project description:BACKGROUND:The importance of socioeconomic status for survival in cirrhosis patients is more or less pronounced within different populations, most likely due to cultural and regional differences combined with dissimilarities in healthcare system organisation and accessibility. Our aim was to study the survival of patients with cirrhosis in a population-based Swedish cohort, using available data on marital status, employment status, and occupational skill level. METHODS:We conducted a retrospective cohort study of 582 patients diagnosed with cirrhosis in the Region of Halland (total population 310,000) between 2011 and 2018. Medical and histopathologic data, obtained from registries, were reviewed. Cox regression models were used to estimate associations between survival and marital status (married, never married, previously married), employment status (employed, pensioner, disability retired, unemployed), and occupational skill level (low-skilled: level I; medium-skilled: level II; medium-high skilled: level III; professionals: level IV); adjusting for sex, age, aetiology, Model for End-stage Liver Disease (MELD) score, Child-Pugh class, and comorbidities. RESULTS:Alcohol was the most common aetiology (51%). Most patients were male (63%) and the median age was 66?years. Occupational skill level was associated with the severity of cirrhosis at diagnosis and the prevalence of Child-Pugh C gradually increased from professionals through low-skilled. The mean survival for professionals (6.39?years, 95% CI 5.54-7.23) was higher than for low-skilled (3.00?years, 95% CI 2.33-3.67) and medium-skilled (4.04?years, 95% CI 3.64-4.45). The calculated hazard ratios in the multivariate analysis were higher for low-skilled (3.43, 95% CI 1.89-6.23) and medium-skilled (2.48, 95% CI 1.48-4.12), compared to professionals. When aggregated, low- and medium-skilled groups also had poorer mean survival (3.79?years, 95% CI 3.44-4.14; vs 5.64?years, 95% CI 5.00-6.28) and higher hazard ratios (1.85, 95% CI 1.32-2.61) compared to the aggregated medium-high skilled and professional groups. Marital and employment status were not statistically significant predictors of mortality in the multivariate analysis. CONCLUSIONS:Occupational skill level was strongly associated with mean survival and mortality risk. Poorer prognosis among patients with low and medium occupational skill level could not be explained by differences in sex, age, marital status, employment status, MELD score, Child-Pugh class, or comorbidity.

Project description:ObjectiveTo compare perinatal outcomes in births of women with versus without a history of bariatric surgery.DesignPopulation based matched cohort study.SettingSwedish national health service.Participants1,742,702 singleton births identified in the Swedish medical birth register between 1992 and 2009. For each birth to a mother with a history of bariatric surgery (n=2562), up to five control births were matched by maternal age, parity, early pregnancy body mass index, early pregnancy smoking status, educational level, and year of delivery. Secondary control cohorts, including women eligible for bariatric surgery (body mass index ? 35 or ? 40), were matched for the same factors except body mass index. History of maternal bariatric surgery was ascertained through the Swedish national patient register from 1980 to 2009.Main outcome measuresPreterm birth (<37 weeks), small for gestational age birth, large for gestational age birth, stillbirth (? 28 weeks), and neonatal death (0-27 days).ResultsPost-surgery births were more often preterm than in matched controls (9.7% (243/2511) v 6.1% (750/12,379); odds ratio 1.7, 95% confidence interval 1.4 to 2.0; P<0.001). Body mass index seemed to be an effect modifier (P=0.01), and the increased risk of preterm birth was only observed in women with a body mass index <35. A history of bariatric surgery was associated with increased risks of both spontaneous (5.2% (130/2511) v 3.6% (441/12,379); odds ratio 1.5, 1.2 to 1.9; P<0.001) and medically indicated preterm birth (4.5% (113/2511) v 2.5% (309/12,379); odds ratio 1.8, 1.4 to 2.3; P<0.001). A history of bariatric surgery was also associated with an increased risk of a small for gestational age birth (5.2% (131/2507) v 3.0% (369/12,338); odds ratio 2.0, 1.5 to 2.5; P<0.001) and lower risk of a large for gestational age birth (4.2% (105/2507) v 7.3% (895/12,338); odds ratio 0.6, 0.4 to 0.7; P<0.001). No differences were detected for stillbirth or neonatal death. The increased risks for preterm and small for gestational age birth, as well as the decreased risk for large for gestational age birth, remained when post-surgery births were compared with births of women eligible for bariatric surgery.ConclusionWomen with a history of bariatric surgery were at increased risk of preterm and small for gestational age births and should be regarded as a risk group during pregnancy.
