- BackgroundEsophageal cancer surgery reduces patients’ health-related quality of life (HRQoL). This study examined whether comorbidities influence HRQoL in these patients.MethodsThis prospective cohort study included esophageal cancer patients having undergone curatively intended esophagectomy at St Thomas’ Hospital London in 2011–2015. Clinical data were collected from patient reports and medical records. Well-validated cancer-specific and esophageal cancer-specific questionnaires (EORTC QLQ-C30 and QLQ-OG25) were used to assess HRQoL before and 6 months after esophagectomy. Number of comorbidities, American Society of Anesthesiologists physical status classification (ASA), and specific comorbidities were analyzed in relation to HRQoL aspects using multivariable linear regression models. Mean score differences with 95% confidence intervals were adjusted for potential confounders.ResultsAmong 136 patients, those with three or more comorbidities at the time of surgery had poorer global quality of life and physical function and more fatigue compared with those with no comorbidity. Patients with ASA III–IV reported more problems with the above HRQoL aspects and worse social function and pain compared with those with ASA I–II. Cardiac comorbidity was associated with worse global quality of life and dyspnea, while pulmonary comorbidities were related to coughing. Patients assessed both before and 6 months after surgery (n = 80) deteriorated in most HRQoL aspects regardless of comorbidity status, but patients with several comorbidities had worse physical function and fatigue and more trouble with coughing compared with those with fewer comorbidities.ConclusionComorbidity appears to negatively influence HRQoL before esophagectomy, but appears not to severely impact 6-month recovery of HRQoL.

- It is unclear whether gastrectomy or oesophagectomy offer better outcomes for gastro-oesophageal junction (GOJ) cancer. A total of 240 patients undergoing total gastrectomy (n = 85) or oesophagectomy (n = 155) for Siewert II-III GOJ adenocarcinoma were identified from a Swedish prospective population-based nationwide cohort. The surgical approaches were compared in relation to non-radical resection margins (main outcome) using multivariable logistic regression, providing odds ratios (ORs) and 95% confidence intervals (CIs), mean number of removed lymph nodes with standard deviation (SD) using ANCOVA, assessing mean differences and 95% CIs, and 5-year mortality using Cox regression estimating hazard ratios (HRs) and 95% CIs. The models were adjusted for age, sex, comorbidity, tumour stage, and surgeon volume. The non-radical resection rate was 15% for gastrectomy and 14% for oesophagectomy, and the adjusted OR was 1.61 (95% CI 0.68-3.83). The mean number of lymph nodes removed was 14.2 (SD +/- 9.6) for gastrectomy and 14.2 (SD +/- 10.4) for oesophagectomy, with adjusted mean difference of 2.4 (95% CI-0.2-5.0). The 5-year mortality was 76% following gastrectomy and 75% following oesophagectomy, with adjusted HR = 1.07 (95% CI 0.78-1.47). Gastrectomy and oesophagectomy for Siewert II or III GOJ cancer seem comparable regarding tumour-free resection margins, lymph nodes removal, and 5-year survival.

- Purpose: Little is known about cancer incidence among patients with a history of suicide attempt. Suicide attempters have lower levels of oxytocin, a hormone related to lactation, stress, social functioning, and well-being, and recent research indicates influence on carcinogenesis. We hypothesized that the low oxytocin levels among suicide attempters results in an increased risk of cancer in general and in organs with oxytocin receptors in particular.Methods: A nationwide cohort study of patients aged 15 years or older with hospitalization for self-inflicted injury or attempted suicide was identified from the Swedish patient register in 1968–2011. The cancer outcomes were identified from the Swedish cancer register. Cancer risk in suicide attempters was compared with the risk in the background population of the corresponding age, sex, and calendar period by calculating standardized incidence ratios (SIRs) with 95 % confidence intervals (95 % CI).Results: The 186,627 patients (83,637 men and 102,990 women) hospitalized for self-inflicted injury or attempted suicide contributed with 2.6 million person-years at risk. The SIR for all cancer was 1.3 (95 % CI 1.27–1.33) in men and 1.25 (1.22–1.28) in women. For cancers in organs rich in oxytocin receptors (uterus, breast, and brain), the corresponding SIRs were 1.02 (0.87–1.19) and 1.13 (1.09–1.17), respectively. There was a particularly increased risk of cancers related to alcohol and tobacco in both sexes.Conclusion: Patients attempting suicide have an increased risk of cancer. However, this increase does not seem to be associated with low oxytocin levels, but rather to exposures like tobacco smoking and alcohol consumption.

- BackgroundPostoperative mortality is traditionally defined as death within 30 days of surgery. We hypothesised that the declining 30-day mortality after oesophageal cancer resection is, at least partly, explained by a shift towards increased 90-day mortality.MethodsThis population-based cohort study included 95 % of all patients who underwent surgical resection for oesophageal cancer in Sweden in 1987–2010. Cox proportional-hazards regression models were used to calculate hazard ratios (HRs) with 95 % confidence intervals (CIs) of 30-day and 31–90 days postoperative mortality in three calendar periods (1987–1994, 1995–2002, and 2003–2010). Adjustments were made for age, sex, comorbidity, tumour stage, tumour histology, surgical radicality, neoadjuvant therapy, and hospital volume of oesophagectomy.ResultsAmong 1,822 patients, the 30-day postoperative mortality decreased from 9.3 % in 1987–1994 to 3.0 % in 2003–2010, while the corresponding 31–90 days mortality decreased from 8.4 to 4.6 %. The adjusted HR of 30-day mortality in the earliest period was markedly increased compared to the latest period (HR 3.26; 95 % CI 1.96–5.45), whereas the corresponding HR of 31–90 days mortality was weaker (HR 2.16; 95 % CI 1.34–3.46). Among patients who died within 90 days of surgery, the proportion of 31–90 days mortality increased from 47 to 61 % during the study period.ConclusionsThis population-based study indicates a shift of postoperative mortality following surgery for oesophageal cancer from 30 days to 31–90 days with more recent calendar periods. Reporting of 90-day mortality rates might replace 30-day mortality rates in assessing early postoperative mortality in oesophageal cancer patients.

- BACKGROUND: The selection for surgery is multifaceted for patients diagnosed with esophageal cancer. Since it is uncertain how comorbidity should influence the selection, this study addressed comorbidities in relation to risk of severe complications following esophageal cancer surgery.METHODS: This population-based cohort study was based on prospectively included patients who underwent surgical resection for an esophageal or gastro-esophageal junctional cancer in Sweden during 2001-2005. The participation rate was 90%. Associations between pre-defined comorbidities and pre-defined post-operative complications occurring within 30 days of surgery were analyzed using multivariable logistic regression. The resulting odds ratios (ORs) and 95% confidence intervals (CIs) were adjusted for age, sex, tumor stage, tumor histology, neoadjuvant therapy, type of surgery, annual hospital volume, other comorbidities, and other complications.RESULTS: Among 609 included patients, those with cardiac disease (n = 92) experienced an increased risk of pre-defined complications in general (adjusted OR 1.81, 95% CI 1.13-2.90), while patients with hypertension (n = 137), pulmonary disorders (n = 79), diabetes (n = 67), and obesity (n = 66) did not. Patients with a Charlson comorbidity index score ≥2 had substantially increased risks of pre-defined complications (adjusted OR 2.44, 95% CI 1.60-3.72).CONCLUSION: Cardiac disease and a Charlson comorbidity index score ≥2 seem to increase the risk of severe and early post-operative complications in patients with esophageal cancer, while hypertension, pulmonary disorders, diabetes, and obesity do not. These findings should be considered in the clinical decision-making for improved selection of patients for surgery.

- Objective: To examine the hypothesis that survival in esophageal cancer increases with more removed lymph nodes during esophagectomy up to a plateau, after which it levels out or even decreases with further lymphadenectomy.Summary of Background Data: There is uncertainty regarding the ideal extent of lymphadenectomy during esophagectomy to optimize long-term survival in esophageal cancer.Methods: This population-based cohort study included almost every patient who underwent esophagectomy for esophageal cancer in Sweden or Finland in 2000-2016 with follow-up through 2019. Degree of lymphadenectomy, divided into deciles, was analyzed in relation to all-cause 5-year mortality. Multivariable Cox regression provided hazard ratios (HR) with 95% confidence intervals (95% CI) adjusted for all established prognostic factors.Results: Among 2,306 patients, the 2nd (4-8 nodes), 7th (21-24 nodes) and 8th decile (25-30 nodes) of lymphadenectomy showed the lowest all-cause 5-year mortality compared to the 1st decile (HR = 0.77, 95% CI 0.61-0.97, HR = 0.76, 95% CI 0.59-0.99, and HR = 0.73, 95% CI 0.57-0.93, respectively). In stratified analyses, the survival benefit was greatest in decile 7 for patients with pathological T-stage T3/T4 (HR = 0.56, 95% CI 0.40-0.78), although it was statistically improved in all deciles except decile 10. For patients without neoadjuvant chemotherapy, survival was greatest in decile 7 (HR = 0.60, 95% CI 0.41-0.86), although survival was also statistically significantly improved in deciles 2, 6, and 8.Conclusion: Survival in esophageal cancer was not improved by extensive lymphadenectomy, but resection of a moderate number (20-30) of nodes was prognostically beneficial for patients with advanced T-stages (T3/T4) and those not receiving neoadjuvant therapy.

- Background: Psychological distress is common among patients with oesophageal cancer. However, little is known about the course and predictors of psychological distress among patients treated with curative intent. Therefore, the aim of this study was to explore the prevalence, course and predictors of anxiety and depression in patients operated for oesophageal cancer, from prior to surgery to 12 months post-operatively. Methods: A prospective cohort of patients with oesophageal cancer (n ¼ 218) were recruited from one high-volume specialist oesophago-gastric treatment centre (St Thomas’ Hospital, London, UK). Anxiety and depression were assessed prior to surgery, 6 and 12 months post-operatively. Mixed-effects modelling was performed to investigate changes over time and to estimate the association between clinical and socio-demographic predictor variables and anxiety and depression symptoms. Results: The proportion of patients with anxiety was 33% prior to surgery, 28% at 6 months, and 37% at 12 months. Prior to surgery, 20% reported depression, 27% at 6 months, and 32% at 12-month follow-up. Anxiety symptoms remained stable over time whereas depression symptoms appeared to increase from pre-surgery to 6 months, levelling off between 6 and 12 months. Younger age, female sex, living alone and more severe self-reported dysphagia (i.e., difficulty swallowing) predicted higher anxiety symptoms. In-hospital complications, greater limitations in activity status and more severe selfreported dysphagia were predictive of higher depression. Conclusions: Many patients report psychological distress during the first year following oesophageal cancer surgery. Whether improving the experience of swallowing difficulties may also reduce distress among these patients warrants further study.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- It is uncertain whether coeliac node metastasis precludes long-term survival in distal oesophageal cancer. This nationwide population-based cohort study included patients who underwent surgical resection for stage III or IV distal oesophageal cancer in 1987-2010 with follow-up until 2014. A minority (17.0%) had neoadjuvant therapy. The prognosis in patients with coeliac node metastasis was compared with patients with no such metastasis and patients with more distant metastasis. Multivariable Cox proportional-hazards regression models provided hazard ratios (HRs) with 95% confidence intervals (CIs) of disease-specific and overall mortality. Among 446 patients, 346 (77.6%) had no coeliac node metastasis, 56 (12.6%) had coeliac node metastasis, and 44 (9.9%) had more distant metastasis. Compared to coeliac node negative patients, coeliac node positive patients were at a 52% increased risk of disease-specific mortality (HR = 1.52, 95% CI 1.10-2.10), while patients with more distant metastasis had a 27% statistically non-significant increase (HR = 1.27, 95% CI 0.88-1.83). Patients with distant metastasis had no increase in disease-specific mortality compared to those with coeliac node metastasis (HR 0.71, 95% CI 0.40-1.27). Thus, patients with distal oesophageal cancer with coeliac node metastasis seem to have a similarly poor survival as patients with more distant metastasis, and thus may not benefit from surgery.
