- Objectives: This study aimed to investigate whether a higher education level is associated with an improved long-term survival after oesophagectomy for cancer. Design: A prospective, population-based cohort study. Setting: Sweden—nationwide. Participants: 90% of all patients with oesophageal and cardia cancer who underwent a resection in Sweden in 2001–2005 were enrolled in this study (N=600; 80.3% male) and followed up until death or the end of the study period (2012). The study exposure was level of education, defined as compulsory (≤9 years), moderate (10–12 years) or high (≥13 years). Outcome measures The main outcome measure was overall 5-year survival after oesophagectomy. Cox regression was used to estimate the associations between education level and mortality, expressed as HRs with 95% CIs, with adjustment for sex, age, tumour stage, histological type, complications, comorbidities and annual surgeon volume. The patient group with highest education was used as the reference category. Results: Among the 600 included patients, 281 (46.8%) had compulsory education, 238 (39.7%) had moderate education and 81 (13.5%) had high education. The overall 5-year survival rate was 23.1%, 24.4% and 32.1% among patients with compulsory, moderate and high education, respectively. After adjustment for confounders, a slightly higher, yet not statistically significantly increased point HR was found among the compulsory educated patients (HR 1.08, 95% CI 0.80 to 1.47). In patients with tumour stage IV, increased adjusted HRs were found for compulsory (HR 2.88, 95% CI 1.07 to 7.73) and moderately (HR 2.83, 95% CI 1.15 to 6.95) educated patients. No statistically significant associations were found for the other tumour stages. Conclusions: This study provides limited evidence of an association between lower education and worse long-term survival after oesophagectomy for cancer.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: This study was undertaken to test the extent to which a new antibiotic prophylaxis regimen for percutaneous endoscopic gastrostomy (PEG), identified as a justified and simpler alternative to conventional regimen in a randomised clinical trial, has been adopted in clinical practice. DESIGN: A Swedish nationwide implementation survey, conducted in February 2013, assessed the level of clinical implementation of a 20 ml dose of oral solution of sulfamethoxazole and trimethoprim deposited in the PEG catheter immediately after insertion. All hospitals inserting at least five PEGs annually were identified from the Swedish Patient Registry. A clinician involved in the PEG insertions at each hospital participated in a structured telephone interview addressing their routine use of antibiotic prophylaxis. SETTING: All Swedish hospitals inserting PEGs (n=60). PARTICIPANTS: Representatives of PEG insertions at each of the 60 eligible hospitals participated (100% participation). MAIN OUTCOME MEASURES: Use of routine antibiotic prophylaxis for PEG. RESULTS: A total of 32 (53%) of the 60 hospitals had adopted the new regimen. It was more frequently adopted in university hospitals (67%) than in community hospitals (41%). An annual total of 1813 (70%) of 2573 patients received the new regimen. Higher annual hospital volume was associated with a higher level of adoption of the new regimen (80% in the highest vs 31% in the lowest). CONCLUSIONS: The clinical implementation of the new antibiotic prophylaxis regimen for PEG was high and rapid (70% of all patients within 3 years), particularly in large hospitals.

Tidskriftsartikel (refereegranskat)abstract
- The 7-to-1 male-to-female ratio in esophageal and gastroesophageal junctional adenocarcinoma (EAC) might be explained by abdominal adiposity, typical for males. If true, a stronger male predominance in higher BMI categories is expected. We conducted a nationwide Swedish population-based case-control study in 1995-1997 and collected data on BMI and other variables at face-to-face interviews. Age-adjusted relative risk (RR) and 95% confidence intervals (CI) levels were calculated using Poisson regression. Among 451 EAC cases and 820 controls, RR of EAC in males compared to females did not increase with higher BMI as assessed 20 years before interview, at 20 years of age, or at maximum or minimum adult BMI. For BMI 20 years before interview, RR in males compared to females were 7.4 (95%CI:3.9-14.1), 5.3 (95%CI:3.5-8.1), and 5.8 (95%CI:3.9-8.8) in the BMI categories <22, 22-<25, and ≥25, respectively. Conclusions: Abdominal adiposity might not explain the male predominance in esophageal adenocarcinoma.

- BACKGROUND: There are few population-based studies addressing the survival after resection for esophageal cancer. This study represents an update of a nationwide Swedish cohort initiated in 1987.METHODS: Based on data from the Swedish Patient Register, Swedish Cancer Register, and histopathologic records, 1,008 patients who had undergone esophageal resection as the only treatment for esophageal cancer were identified between January 1, 1987 and December 31, 2005. These were followed until death or emigration through linkage to the Swedish Total Population Register until January 1, 2009. Tumor stage, location, and histology were assessed from histopathologic reports, and comorbidities were assessed from the Patient Register. Cox proportional hazards regression models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs) regarding survival. The results were adjusted for age, sex, comorbidity, tumor stage, location, histology, surgical radicality, and hospital volume.RESULTS: The proportion of patients surviving for 5 years increased from 19.7% in 1987-1991 to 30.7% in 1997-2000, but remained at 30.5% between 2001 and 2005. No difference in overall adjusted survival was found between the periods of 2001-2005 and 1997-2000 (adjusted HR, 0.89; 95% CI, 0.70-1.13). Thirty-day mortality decreased from 4.9% in 1997-2000 to 2.0% in 2001-2005, rendering an adjusted HR of 0.26 (95% CI, 0.08-0.87).CONCLUSION: After adjusting for relevant prognostic factors, long-term population-based survival after resection for esophageal cancer was unchanged between 2001 and 2005 compared to 1997-2000, while the corresponding 30-day mortality improved.

- OBJECTIVES: The influence of reoperation on long-term prognosis is unknown. In this large population-based cohort study, it was aimed to investigate the influence of a reoperation within 30 days of oesophageal cancer resection on survival even after excluding the initial postoperative period.DESIGN: This was a nationwide population-based retrospective cohort study.SETTING: All hospitals performing oesophageal cancer resections during the study period (1987-2010) in Sweden.PARTICIPANTS: Patients operated for oesophageal cancer with curative intent in 1987-2010.PRIMARY AND SECONDARY OUTCOMES: Adjusted HRs of all cause, early and late mortality up to 5 years after reoperation following oesophageal cancer resection.RESULTS: Among 1822 included patients, the 200 (11%) who were reoperated had a 27% increased HR of all-cause mortality (adjusted HR 1.27, 95% CI 1.05 to 1.53) and 28% increased HR of disease-specific mortality (adjusted HR 1.28, 95% CI 1.04 to 1.59), compared to those not reoperated. Reoperation for anastomotic insufficiency in particular was followed by an increased mortality (adjusted HR 1.82, 95% CI 1.19 to 2.76).CONCLUSIONS: This large and population-based nationwide cohort study shows that reoperation within 30 days after primary oesophageal resection was associated with increased mortality, even after excluding the initial 3 months after surgery. This finding stresses the need to consider any actions that might prevent complications and reoperation after oesophageal cancer resection.
