RESUMO
BACKGROUND: The purpose of this study was to examine the rates of 90-day anastomotic complications and other postoperative complications after total or partial gastrectomy with antecolic versus retrocolic reconstruction in a population-based setting. METHODS: This population-based nationwide retrospective cohort study included all patients undergoing total or partial gastrectomy for gastric adenocarcinoma in Finland in 2005-2016, with follow-up until 31 December 2019. Logistic regression provided odds ratios (ORs) with 95% confidence intervals (CIs) of 90-day mortality. Results were adjusted for age, sex, year of the surgery, comorbidities, tumor locations, pathological stage, and neoadjuvant therapy. RESULTS: A total of 2063 patients having gastrectomy with antecolic (n = 814) or retrocolic (n = 1249) reconstruction were identified from the registries. The anastomotic complication rate was 3.8% with antecolic reconstruction and 5.0% with retrocolic reconstruction. Antecolic reconstruction was not associated with a higher risk of anastomotic complications compared with retrocolic reconstruction in the adjusted analysis (OR 0.69, 95% CI 0.44-1.09) of the whole cohort or in the predefined subgroups. The reoperation rate was 8.2% with antecolic reconstruction and 7.7% with retrocolic reconstruction, without statistical significance. In subgroup analysis of total gastrectomy patients, the risk of major complications was lower with antecolic reconstruction compared with retrocolic reconstruction (OR 0.62, 95% CI 0.45-0.86). CONCLUSIONS: The rate of anastomotic complications did not differ after antecolic versus retrocolic reconstruction after total or partial gastrectomy. In total gastrectomies, the risk of major complications was lower after antecolic compared with retrocolic reconstruction.

BACKGROUND: This study aimed to examine the rate of delayed emptying and other 90-day postoperative complications after total, subtotal, and distal gastrectomies for gastric adenocarcinoma in a population-based setting. METHODS: This study included all patients who underwent total, subtotal, or distal gastrectomy for gastric cancer in Finland in 2005-2016, with follow-up until December 31, 2019. Logistic regression provided the odds ratios with 95% CIs of 90-day mortality. The results were adjusted for age, sex, year of surgery, comorbidities, pathologic stage, and neoadjuvant therapy. RESULTS: A total of 2058 patients underwent total (n = 1227), subtotal (n = 450), or distal (n = 381) gastrectomy. In the total, subtotal, and distal gastrectomy groups, the rates of 90-day delayed emptying were 1.7%, 1.3%, and 2.1% in the whole cohort and 1.6%, 1.8%, and 3.5% in the subgroup analysis of R0 resections, respectively. The resection type was not associated with the risk of delayed emptying. Subtotal gastrectomy was associated with a lower risk of major complications and reoperations, whereas distal gastrectomy was associated with a lower risk of anastomotic complications. CONCLUSION: The extent of resection did not affect delayed emptying, whereas fewer postoperative complications were observed after subtotal or distal gastrectomy than after total gastrectomy.

BACKGROUND: In the Nordic countries, universal healthcare access has been effective in reducing socioeconomic disparities in non-small-cell lung cancer (NSCLC) management. However, other factors, such as proximity to healthcare facilities, may still affect access to care. This study aimed at investigating the influence of residential area on NSCLC survival. METHODS: This population-based study utilized hospital records to identify NSCLC patients who underwent their initial treatment at Vaasa Central Hospital between January 1, 2016, and December 31, 2020. Patients were categorized based on their postal codes into urban areas (≤50 km from the hospital) and rural areas (>50 km from the hospital). Survival rates between these two groups were compared using Cox regression analysis. RESULTS: A total of 321 patients were included in the study. Patients residing in rural areas (n = 104) exhibited poorer 12-month survival rates compared to their urban counterparts (n = 217) (unadjusted Hazard Ratio [HR]: 1.38; 95% Confidence Interval [CI]: 1.01-1.89; p = 0.042). After adjusting for factors such as performance status, frailty, and stage at diagnosis in a multivariate Cox regression model, the adjusted HR increased to 1.47 (95% CI: 1.07-2.01; p = 0.017) for patients living in rural areas compared to those in urban areas. INTERPRETATION: The study findings indicate that the distance to the hospital is associated with increased lung cancer mortality. This suggests that geographical proximity may play a crucial role in the disparities observed in NSCLC survival rates. Addressing these disparities should involve strategies aimed at improving healthcare accessibility, particularly for patients residing in rural areas, to enhance NSCLC outcomes and reduce mortality.

BACKGROUND: There is a lack of evidence regarding anastomotic technique and postoperative complications in gastric cancer surgery. This study aimed to evaluate whether there are differences between stapled and handsewn anastomosis and anastomotic leaks. METHODS: This was a population-based, retrospective, nationwide cohort study in Finland using the Finnish National Esophago-Gastric Cancer Cohort. Patients undergoing gastrectomy with available postoperative complication data were included. Logistic regression analysis was used to calculate the odds ratios with 95% CIs, adjusted for calendar period of surgery, age at surgery, sex, comorbidity, tumor stage, neoadjuvant therapy, minimally invasive surgery, type of gastrectomy, radical resection, and type of anastomosis. RESULTS: Of the 2164 patients, 472 of all patients (21.8%) had handsewn anastomosis and 1692 of all patients (78.2%) had stapled anastomosis. In the unadjusted analysis, anastomotic leaks were significantly lower in the handsewn group (hazard ratio [HR], 0.42; 95% CI, 0.22-0.79) than the stapled group, but after adjustment for known prognostic factors, this association was no longer significant (HR, 0.57; 95% CI, 0.27-1.21). In the analysis stratified by gastrectomy type (distal or total), no differences in anastomotic leaks were observed between anastomotic techniques. CONCLUSION: In this population-based nationwide study, anastomotic technique (stapled or handsewn) was not associated with anastomotic leaks in any, distal or total, gastrectomy.

OBJECTIVES: The desirable lymph node count was determined to maximize the survival time expectancy according to the lymph node count among patients who have undergone oesophagectomy for oesophageal cancer. METHODS: The data of national Finnish population-based cohort including all patients who have undergone oesophagectomy due to oesophageal cancer during 2002-2016 were used. Restricted mean survival time (RMST) estimates were determined by lymph node count, and the desirable count was determined using locally estimated scatterplot smoothing regression. RESULTS: A total of 883 patients with the median follow-up time of 3.73 (interquartile range 1.43-7.50) years were included. The lymph node count of 27 (95% confidence interval 25-28) was associated with the highest RMST estimates. Sensitivity analyses indicated that in pN0 patients, the highest RMST estimates was observed at 26 (95% confidence interval 24-28) lymph nodes and in pN+ patients, the RMST estimates peaked at 28 (95% confidence interval 25-33) lymph nodes. CONCLUSIONS: According to the findings of this study, at least 24 examined lymph nodes is the recommended target for the lymph node count after oesophagectomy for oesophageal cancer. The beneficial effect of this count on survival may be achieved regardless of nodal metastases.

Tumour-associated macrophages (TAMs) express a continuum of phenotypes ranging from an anti-tumoural M1-like phenotype to a pro-tumoural M2-like phenotype. During cancer progression, TAMs may shift to a more M2-like polarisation state, but the role of TAMs in CRC metastases is unclear. We conducted a comprehensive spatial and prognostic analysis of TAMs in CRC pulmonary metastases and corresponding primary tumours using multiplexed immunohistochemistry and machine learning-based image analysis. We obtained data from 106 resected pulmonary metastases and 74 corresponding primary tumours. TAMs in the resected pulmonary metastases were located closer to the cancer cells and presented a more M2-like polarised state in comparison to the primary tumours. Higher stromal M2-like macrophage densities in the invasive margin of pulmonary metastases were associated with worse 5-year overall survival (HR 3.19, 95% CI 1.35-7.55, p = 0.008). The results of this study highlight the value of multiplexed analysis of macrophage polarisation in cancer metastases and might have clinical implications in future cancer therapy.

BACKGROUND: To date, no large population-based studies have compared complications and short-term outcomes between neoadjuvant chemotherapy and upfront surgery in gastric cancer. More nationwide studies with standardized reporting on complications are needed to enable international comparison between studies. This study aimed to compare postoperative complications between neoadjuvant therapy and upfront surgery after gastrectomy for gastric adenocarcinoma in a population-based setting. METHODS: This population-based study based on the Finnish National Esophago-Gastric Cancer Cohort included all patients 18 years of age or older undergoing gastrectomy for gastric adenocarcinoma in Finland during 2005-2016. Logistic regression provided odds ratios (ORs) with 95% confidence intervals (CIs), both crude and adjusted for key confounders. Different types of complications were graded based on the Esophagectomy Complications Consensus Group definitions, and major complications were assessed by the Clavien-Dindo scale. RESULTS: This study analyzed 769 patients. Neoadjuvant chemotherapy did not increase major postoperative complications after gastrectomy for gastric cancer compared with upfront surgery (OR, 1.12; 95% CI 0.81-1.56). Furthermore, it did not increase pneumonia, anastomotic complications, wound complications, or other complications. CONCLUSIONS: Neoadjuvant therapy is not associated with increased postoperative complications, reoperations, or short-term mortality compared with upfront surgery in gastric adenocarcinoma.

BACKGROUND: The incidence of postoperative complications after gastrectomy for gastric cancer is not well known. More population-based studies using established complication classifications are needed for international comparison. The aim of this study was to evaluate the population-based incidence of postoperative complications after gastrectomy for gastric cancer. METHODS: This population-based study based on the Finnish National Esophago-Gastric Cancer Cohort included all patients at least 18 years of age undergoing gastrectomy for gastric adenocarcinoma in Finland during 2005-2016. The occurrence of complications 30 and 90 days after surgery was graded based on the Esophagectomy Complications Consensus Group definitions and the severity of complications was assessed using the Clavien-Dindo scale. RESULTS: This study included a total of 2196 patients. Postoperative complications occurred in 906 (41.3 per cent) of patients during 30 days after surgery and in 946 (43.1 per cent) during 90 days after surgery. Clavien-Dindo grade III or higher complications occurred in 375 (17.1 per cent) of patients. The most common complications 90 days after surgery by Esophagectomy Complications Consensus Group upper-level categories were gastrointestinal (n = 438; 19.9 per cent), including anastomotic leak, infectious (n = 377; 17.2 per cent) and pulmonary (n = 335; 15.3 per cent) complications. Postoperative mortality rate was occurred in 72 (3.3 per cent) patients within 30 days and in 161 (7.3 per cent) patients within 90 days after surgery. The median duration of postoperative hospital stay was 9 days (interquartile range 4-14). CONCLUSIONS: Postoperative complications are common across all types of gastrectomy and the majority occur during the first 30 postoperative days. This study informs the patients and caregivers of the expected outcomes of gastrectomy.

Tertiary lymphoid structures (TLSs) are ectopic lymphoid aggregates located at sites of chronic inflammation and recognized as prognosticators in several cancers. We aimed to analyse the prognostic effect of TLSs in colorectal cancer (CRC) pulmonary metastases and primary tumours, with a comparison to the CD3+ and CD8+ cell density-based immune cell score (ICS). For TLS density and TLS maximum diameter analysis, 67 pulmonary metastases and 63 primary tumours were stained with haematoxylin and eosin. For ICS scoring and analysis, CD3 and CD8 immunohistochemistry was performed. Excellent interobserver agreement was achieved in all TLS measurements. Of all patients, 36 patients had low TLS density (< 0.222 follicles/mm) and 31 patients had high TLS density (≥ 0.222 follicles/mm) in the first resected pulmonary metastases. TLS density (adjusted HR 0.91, 0.48-1.73) or maximum diameter (adjusted HR 0.78, 0.40-1.51) did not have prognostic value in pulmonary metastases. In primary tumours, higher TLS density (adjusted HR 0.39, 0.18-0.87) and maximum diameter (adjusted HR 0.28, 0.11-0.73) were associated with lower mortality. In the pulmonary metastases, ICS had superior prognostic value to TLSs; however, TLSs and ICS were significantly associated. In conclusion, TLSs in CRC pulmonary metastases had no prognostic value but correlated with the ICS. TLSs in primary tumours associated with favourable prognosis.

BACKGROUND: Preoperative esophageal stenting is proposed to have a negative effect on outcomes. The aim was to compare a 5-year survival in patients undergoing esophagectomy for esophageal cancer with and without preoperative esophageal stent in a population-based nationwide cohort from Finland. The secondary outcome was 90-day mortality. METHODS: This study included curatively intended esophagectomies for esophageal cancer in Finland between 1999 and 2016, with follow-up until December 31, 2019. Cox proportional hazards models provided hazard ratios (HRs) with 95% confidence intervals (CIs) of overall 5-year and 90-day mortality. Model 1 was adjusted for age, sex, year of the surgery, comorbidities, histology, pathological stage, and neoadjuvant therapy. Model 2 included also albumin level and BMI. RESULT: Of 1064 patients, a total of 134 patients underwent preoperative stenting and 930 did not. In both adjusted models 1 and 2, higher 5-year mortality was seen in patients with preoperative stent with HRs of 1.29 (95% CI 1.00-1.65) and 1.25 (95% CI 0.97-1.62), respectively, compared to no stenting. The adjusted HR of 90-day mortality was 2.49 (95% CI 1.27-4.87) in model 1 and 2.49 (95% CI 1.25-4.99) in model 2. When including only neoadjuvant-treated patients, those with preoperative stent had a 5-year survival of 39.2% compared to 46.4% without stent (adjusted HR 1.34, 95% CI 1.00-1.80), and a 90-day mortality rate of 8.5% and 2.5% (adjusted HR 3.99, 95% CI 1.51-10.50). DISCUSSION: This nationwide study reports worse 5-year and 90-day outcomes in patients with preoperative esophageal stent. Since residual confounding remains possible, observed difference could be only an association rather than the cause.

OBJECTIVE: To evaluate the prognostic value of tumor budding and tumor-stroma ratio (TSR) in resected pulmonary metastases of colorectal carcinoma (CRC). METHODS: In total, 106 pulmonary metastasectomies were performed to 74 patients in two study hospitals during 2000-2020. All relevant clinical data were retrospectively collected. Tumor budding based on the International Tumor Budding Consensus Conference recommendations and TSR in the first resected pulmonary metastases and primary tumors were evaluated from diagnostic hematoxylin-eosin-stained histopathological slides. RESULTS: 60 patients (85.7%) had low tumor budding (≤5 buds/field) and 10 patients (14.3%) had high tumor budding (>5 buds/field) in their first pulmonary metastases of CRC. 5-year overall survival rates of pulmonary metastasectomy in low and high total tumor budding were 28.3% and 37.3% (p = 0.387), respectively. 19 patients (27.1%) had low TSR and 51 patients (72.9%) had high TSR. The 5-year overall survival rates were 32.9% in low and 28.6% in high TSR of first pulmonary metastases (p = 0.746). Tumor budding and TSR did not provide prognostic value in Cox multivariate analysis. Tumor budding and TSR in resected pulmonary metastases were not associated with those of the primary tumor. CONCLUSION: Tumor budding and TSR in the resected pulmonary metastases of CRC showed no statistically significant prognostic value, however, additional well-powered confirmatory studies are needed.

INTRODUCTION: Age-related disparities in non-small cell lung cancer (NSCLC) treatment are well known, but few studies have assessed the impact of sex on treatment disparities. Disparities in guideline-adherence may explain the superior survival in women with NSCLC. Therefore, we aimed to define patient- and tumor-related factors associated with non-adherence to guidelines in NSCLC management with a special focus on sex and age. PATIENTS AND METHODS: Patients with NSCLC who received first-line treatment at the Vaasa Central Hospital between 2016 and 2020 were included in the study. The primary outcome was guideline adherence, defined as adherent, undertreatment, or overtreatment considering performance status. A binary logistic regression model was used to calculate the adjusted odds ratio (aOR) for non-adherence to treatment guidelines depending on patient- and tumor-related factors. RESULTS: 321 patients were included in the study. Non-adherence was highest in ≥75-year-old women (41.3%), followed by ≥75-year-old men (32.6%), <75-year-old men (27.6%) and lowest in women <75-year-old (19.7%) (p = 0.035). Non-adherent care consisted more often of undertreatment in <75-year-old men than women (26.0% versus 12.1%) and overtreatment in <75-year-old women than men (7.6% versus 1.6%). Non-adherence was associated with stage III disease (aOR 2.21; 95% CI 1.07-4.59), poor pulmonary function (aOR 3.69, 95% CI 1.56-8.71), and Charlson Comorbidity Index 1-2 (aOR 2.09; 95% CI 1.09-4.01). CONCLUSION: Sex- and age-related disparities in guideline adherence were observed in <75-year-old men and in ≥75-year-olds. Stage III NSCLC was associated with non-adherence.

AIM: We compared variability in number of examined lymph nodes between pathologists and analyzed survival implications in lung and esophageal cancer after standardized lymphadenectomy. METHODS: Outcomes of 294 N2 dissected lung cancer patients and 132 2-field dissected esophageal cancer patients were retrospectively examined. The primary outcome was difference in reported lymph node count among pathologists. Secondary outcomes were overall and disease-specific survival related to this count and survival related to the 50% probability cut-off value of detecting metastasis based on the number of examined lymph nodes. RESULTS: The median number of examined lymph nodes in lung cancer was 13 (IQR 9-17) and in esophageal cancer it was 22 (18-29). The pathologist with the highest median number of examined nodes had > 50% higher lymph node yield compared with the pathologist with the lowest median number of nodes in lung (15 vs. 9.5, p = 0.003), and esophageal cancer (28 vs. 17, p = 0.003). Survival in patients stratified by median reported lymph node count in both lung (adjusted RMST ratio < 14 vs. ≥ 14 lymph nodes 0.99, 95% CI 0.88-1.10; p = 0.810) and esophageal cancer (adjusted RMST ratio < 25 vs. ≥ 25 lymph nodes 0.95, 95% CI 0.79-1.15, p = 0.612) was similar. The cut-off value for 50% probability of detecting metastasis by number of examined lymph nodes in lung cancer was 15.7 and in esophageal cancer 21.8. When stratified by this cut-off, no survival differences were seen. CONCLUSION: The quality of lymphadenectomy based on lymph node yield is susceptible to error due to detected variability between pathologists in the number of examined lymph nodes. This variability in yield did not have any survival effect after standardized lymphadenectomy.

OBJECTIVE: The aim of study was to compare overall 5-year survival of esophageal cancer patients undergoing transthoracic esophagectomy with either neck or intrathoracic anastomosis, that is, McKeown and Ivor-Lewis esophagectomy. BACKGROUND: No national studies comparing long-term survival after McKeown and ivor-Lewis esophagectomies in the West exist. METHODS: This population-based nationwide study included all curatively intended transthoracic esophagectomies for esophageal adenocarcinoma or squamous cell carcinoma in Finland in 1987 to 2016, with follow-up until December 31, 2019. Cox proportional hazard models provided hazard ratios (HR) with 95% confidence intervals (ci) of all-cause 5-year mortality. The results were adjusted for age, sex, year of the operation, comorbidities, histology, stage, and neoadjuvant treatment. Adjusted model 2 included also tumor location and lymph node yield. RESULTS: A total of 990 patients underwent McKeown (n = 278) or Ivor-Lewis (n = 712) esophagectomy The observed overall 5-year survival was 43.1% after McKeown, and 45.9% after Ivor-Lewis esophagectomy. McKeown esophagectomy was not associated with the overall 5-year mortality (adjusted HR 1.11, 95% CI: 0.89-1.38), compared to Ivor-Lewis esophagectomy. Additional adjustment for tumor location and lymphadenectomy further attenuated the point estimate (HR 1.06, 95% CI: 0.85-1.33). Surgical approach was not associated with 90-day mortality rate (adjusted HR 1.15, 95% CI: 0.67-1.97). CONCLUSIONS: This population-based nationwide study suggests that overall 5-year survival or 90-day survival with McKeown and Ivor-Lewis esopha-gectomy for esophageal cancer are comparable.

BACKGROUND: No population-based studies comparing long-term survival after transhiatal esophagectomy (THE) and transthoracic esophagectomy (TTE) exist. This study aimed to compare the 5-year survival of esophageal cancer patients undergoing THE or TTE in a population-based nationwide setting. METHODS: This study included all curatively intended THE and TTE for esophageal cancer in Finland during 1987-2016, with follow-up evaluation until 31 December 2019. Cox proportional hazard models provided hazard ratios (HRs) with 95% confidence intervals (CIs) of 5-year and 90-day mortality. The results were adjusted for age, sex, year of operation, comorbidities, histology, neoadjuvant treatment, and pathologic stage. RESULTS: A total of 1338 patients underwent THE (n = 323) or TTE (n = 1015). The observed 5-year survival rate was 39.3% after THE and 45.0% after TTE (p = 0.072). In adjusted model 1, THE was not associated with greater 5-year mortality (HR 0.99; 95% CI 0.82-1.20) than TTE. In adjusted model 2, including T stage instead of pathologic stage, the 5-year mortality hazard rates after THE (HR 0.87, 95% CI 0.72-1.05) and TTE were comparable. The 90-day mortality rate for THE was higher than for TTE (adjusted HR 0.72; 95% CI 0.45-1.14). In subgroup analyses, no differences between THE and TTE were observed in Siewert II gastroesophageal junction cancers, esophageal cancers, or pN0 tumors, nor in the comparison of THE and TTE with two-field lymphadenectomy. The sensitivity analysis, including patients with missing patient records, who underwent surgery during 1996-2016 mirrored the main analysis. CONCLUSIONS: This Finnish population-based nationwide study suggests no difference in 5-year or 90-day mortality after THE and TTE for esophageal cancer.

BACKGROUND: Multimodal treatment of gastric cancer includes careful preoperative staging, perioperative oncological treatment, and selective minimally invasive approach. The aim was to evaluate whether this approach improves short- and long-term outcomes in operable gastric cancer. METHODS: This study included 181 gastric cancer patients who underwent curative intent surgery in Central Finland Central Hospital between years 2005 and 2021 for gastric or esophagogastric junction adenocarcinoma. Those 65 patients in group 1 operated between years 2005-2010 had open surgery with possible adjuvant therapy. During the second period including 58 patients (2011-2015), perioperative chemotherapy and minimally invasive surgery were implemented. The period, when these treatments were standard practise, was years 2016-2021 including 58 patients (group 3). Outcomes were lymph node yield, major complications and 1- and 3-year survival rates. RESULTS: Median lymph node yield increased from 17 in group 1 and 20 in group 2 to 23 in group 3 (p < 0.001). Major complication rates in groups 1-3 were 12.3%, 32.8%, and 15.5% (group 1 vs. group 2, p = 0.007; group 2 vs. group 3, p = 0.018), respectively. Overall 1-year survival rates between study groups 1-3 were 78.5% vs. 69.0% vs. 90.2% (p = 0.018) and 3-year rates 44.6% vs. 44.8% vs. 68.1% (p = 0.016), respectively. For overall 3-year mortality, adjusted hazard ratio (HR) was 1.02 (95%CI 0.63-1.66) in group 2 and HR 0.37 (95%CI 0.20-0.68) in group 3 compared to group 1. CONCLUSIONS: In medium-volume center, modern multimodal therapy in operable gastric cancer combined with minimally invasive surgery increased lymph node yield and improved long-term survival without increasing postoperative morbidity.

OBJECTIVES: Mean age at diagnosis of lung cancer is increasing with increasing age in Western populations. The present study was designed to evaluate the effect of adherence to first-line treatment guidelines on overall survival (OS) in elderly patients with non-small-cell lung cancer (NSCLC) and reasons for non-adherence to treatment guidelines. MATERIALS AND METHODS: All patients aged ≥ 65 years diagnosed with NSCLC in Ostrobothnia, Finland, during the years 2016 to 2020 were identified from hospital registries. Adherence of first-line treatment to contemporary treatment guidelines was analysed based on diagnosis, tumour stage and performance status (PS), as was the effect of adherence on OS. RESULTS: A review of hospital registries identified 238 NSCLC patients aged ≥ 65 years. Guideline adherence by stage decreased significantly with age, with 66.4% of patients aged 65 to 74 years, but only 33.3% of those aged > 80 years treated according to guidelines (p < 0.001). Other factors associated with non-adherence to guidelines included poor PS, frailty, and limited lung function. Of the patients with PS 0-2, 26.9% were under-treated according to guidelines. Reasons for under-treatment included comorbidities, decreased lung function, physician decision to reduce treatment intensity or recommend best supportive care, patient choice and PS decline before treatment initiation. Guideline adherence increased overall OS of elderly NSCLC patients in all stages. Elderly PS 2 patients appear to benefit from guideline adherence and active treatment. In contrast, active treatment did not benefit patients with PS 3-4. CONCLUSIONS: Guideline adherence was associated with increased OS in elderly NSCLC patients. Almost 10% of elderly and otherwise fit NSCLC patients were not treated according to guidelines and could have benefitted from more intensive treatment.
