- Background. Multidisciplinary team (MDT) conferences have been introduced into standard cancer care, though evidence that it benefits the patient is weak. We used the national Swedish Rectal Cancer Register to evaluate predictors for case discussion at a MDT conference and its impact on treatment.Material and methods. Of the 6760 patients diagnosed with rectal cancer in Sweden between 2007 and 2010, 78% were evaluated at a MDT. Factors that influenced whether a patient was discussed at a preoperative MDT conference were evaluated in 4883 patients, and the impact of MDT evaluation on the implementation of preoperative radiotherapy was evaluated in 1043 patients with pT3c-pT4 M0 tumours, and in 1991 patients with pN+ M0 tumours.Results. Hospital volume, i.e. the number of rectal cancer surgical procedures performed per year, was the major predictor for MDT evaluation. Patients treated at hospitals with < 29 procedures per year had an odds ratio (OR) for MDT evaluation of 0.15. Age and tumour stage also influenced the chance of MDT evaluation. MDT evaluation significantly predicted the likelihood of being treated with preoperative radiotherapy in patients with pT3c-pT4 M0 tumours (OR 5.06, 95% CI 3.08–8.34), and pN+ M0 (OR 3.55, 95% CI 2.60–4.85), even when corrected for co-morbidity and age.Conclusion. Patients with rectal cancer treated at high-volume hospitals are more likely to be discussed at a MDT conference, and that is an independent predictor of the use of adjuvant radiotherapy. These results indirectly support the introduction into clinical practice of discussing all rectal cancer patients at MDT conferences, not least those being treated at low-volume hospitals.

- Introduction: Approximately, 10–15% of lung cancer patients have never smoked. Previous epidemiological studies on non-tobacco associated lung cancer have been hampered by selected data from a small number of hospitals or limited numbers of patients. By use of data from large population-based registers with national coverage, this study aims to compare characteristics and survival of patients with non-small cell lung cancer (NSCLC) with different smoking histories.Methods: Swedish national population-based registers were used to retrieve data on patients diagnosed with primary NSCLC between 2002 and 2016. The Kaplan–Meier method and Cox proportional hazard models were used to estimate overall survival and lung cancer-specific survival by smoking history.Results: In total, 41,262 patients with NSCLC were included. Of those, 4624 (11%) had never smoked. Never-smokers were more often women and older compared to ever smokers (current and former). Adenocarcinoma was proportionally more common in never-smokers (77%) compared to current (52%) and former smokers (57%). Stage IV disease was more common in never-smokers (57%) than in current (48%) and former smokers (48%). Epidermal growth factor receptor mutation was observed more in never-smokers (37%) compared to current (5%) and former smokers (9%). Both lung cancer-specific and overall survival were higher for never-smokers compared to current smokers.Conclusions: The observed differences in characteristics between never-smokers and smokers, and the higher survival in never-smokers compared to smokers from this large population-based study provide further evidence that lung cancer in never-smokers is clinically different to tobacco-associated lung cancer. The findings from this study emphasise the need for an improved understanding of genetics, pathogenesis, mechanisms and progression of non-tobacco associated lung cancer that may help prevent lung cancer or identify individually targeted treatments.

- Objectives: We examined associations between educational level and clinical presentation, patterns of management and mortality in patients with non-small cell lung cancer (NSCLC) in Sweden, a country with a National Health Care System. Materials and Methods: We identified 39,671 patients with a NSCLC diagnosis 2002-2016 in Lung Cancer Data Base Sweden (LCBaSe), a population-based research database. In analyses adjusted for comorbidity and other prognostic factors, odds Ratios (OR) and hazard Ratios (HR) were estimated to examine associations between patients' educational level and aspects of management and mortality. Results: Stage at diagnosis and waiting times did not differ between educational groups. In multivariable analysis, the likelihood to undergo PET/CT and assessment in a multidisciplinary team setting were higher in patients with high compared to low education (aOR 1.14; CI 1.05-1.23 and aOR 1.22; CI 1.14-1.32, respectively). In patients with early stage IA-IIB disease, the likelihood to undergo stereotactic radiotherapy was elevated in patients with high education (aOR 1.40; CI 1.03-1.91). Both all-cause (aHR 0.86; CI 0.77-0.92) and cause specific mortality (aHR 0.83; CI 0.74-0.92) was lower in patients with high compared to low education in early stage disease (IA-IIB). In higher stage NSCLC no differences were observed. Patterns were similar in separate assessments stratified by sex and histopathology. Conclusions: While stage at diagnosis and waiting times did not differ between educational groups, we found socioeconomic differences in diagnostic intensity, multidisciplinary team assessment, stereotactic radiotherapy and mortality in patients with NSCLC. These findings may in part reflect social gradients in implementation and use of novel diagnostic and treatment modalities. Our findings underscore the need for improved adherence to national guidelines.
