The impact of implementing current treatment modalities and female sex on gastric cancer outcomes, 2000-2016: a longitudinal nationwide cohort study.

BACKGROUND: The implementation of current treatment modalities and their impact on nationwide gastric cancer outcomes remain poorly understood. Biological differences between females and males could impact survival. We aimed to analyze rates of gastric surgery, chemotherapy, and radiotherapy as well as changes in overall survival among gastric cancer patients diagnosed between 2000-2008 and 2009-2016, respectively, in Finland. MATERIAL AND METHODS: Data on gastric cancer patients were collected from national registries. Cox regression analysis and the Kaplan-Meier method were used to analyze differences in survival. RESULTS: We identified 9223 histologically confirmed gastric cancer patients. The rate of gastric surgery decreased from 44% (n = 2282) to 34% (n = 1368; p < 0.001). The proportion of gastric surgery patients who underwent preoperative oncological treatment increased from 0.5% (n = 12) to 16.2% (n = 222) between the calendar periods (p < 0.001) and stood at 30% in 2016. The median overall survival (OS) improved from 30 months [95% confidence interval (CI) 28-33] to 38 months (95%CI 33-42; p = 0.006) and the period 2009-2016 independently associated with a lower risk of death [hazard ratio (HR) 0.78, 95%CI 0.70-0.87] among patients who underwent gastric surgery. Females exhibited a lower risk of death (HR 0.88, 95%CI 0.81-0.97) among patients who underwent gastric surgery. CONCLUSION: Preoperative oncological treatment was gradually introduced into clinical practice and OS among gastric surgery patients improved. Moreover, female surgical patients exhibited a better survival than male patients.

Long-term nationwide trends in the treatment of and outcomes among pancreatic cancer patients.

Whilst treatment modalities for pancreatic cancer patients have evolved in recent years, their impact on outcomes remains relatively unexamined on a national scale. We aimed to analyse changes in overall survival and trends in surgical and oncological treatments in pancreatic cancer patients diagnosed in the periods 2000 through 2008 and 2009 through 2016 in Finland. We collected data for pancreatic cancer patients diagnosed between 2000 and 2016, gathering data from the Finnish national registries on surgeries, oncological treatments and time of death. Follow-up continued through the end of 2018. We compared patients diagnosed between 2000 and 2008 to those diagnosed between 2009 through 2016. Our study comprised 14 712 pancreatic cancer patients. There was no significant change in the national resection rate (8.1% vs 8.0%, p = 0.690). In radical surgery patients, median survival improved from 20 months (95% confidence interval (CI) 18-22) to 28 months (CI 25-31) (p < 0.001), with 1-year survival ranging from 70% to 81%. In the no-surgery group, median survival slightly improved from 3.1 months (CI 3.0-3.3) to 3.3 months (CI 3.1-3.4) (p < 0.001). The proportion of radical surgery patients receiving preoperative oncological treatment increased from 4% to 13% (p < 0.001) and only postoperative treatment from 25% to 47% (p < 0.001). Whilst the resection rate did not increase, the prognosis of pancreatic cancer patients improved, particularly amongst radical surgery patients resulting most likely from the fact that a larger proportion of patients receive more effective oncological treatments.

Resection of the stenotic segment with individually tailored anastomosis for symptomatic congenital tracheal stenosis in infants.

OBJECTIVES: To analyse retrospectively population-based results of congenital tracheal stenosis (CTS) repair in infants in Finland. METHODS: Data on infants who were operated on for CTS in Helsinki Children's Hospital between August 1988 and May 2013 were analysed retrospectively. Fibreoptic bronchoscopy was performed perioperatively and in follow-up of all the surviving patients. The median follow-up time was 7 (range 1-20) years. RESULTS: Thirteen infants were operated on for CTS. Resection of the stenotic segment with individually tailored anastomosis was used in 12 patients and slide tracheoplasty in 1 patient. The median age at the operation was 2.9 (range 0.2-19) months. Eight (62%) patients had associated cardiovascular defects, which were corrected during the same operation. The median length of stenosis was 35% (range 25-60%) of the total length of the trachea. The median length of time of postoperative mechanical ventilation was 10 (range 5-19) days. The median length of time of intensive care treatment was 15 (range 7-40) days. One patient died from hypoplastic lung tissue and fibrosis, and multiorgan failure. One patient required reoperation, and 3 other patients received balloon bronchodilatations postoperatively. There was no late mortality. All of the 12 survivors had a good outcome. CONCLUSION: Resection with individually tailored anastomosis with up to 55% of the stenotic segment of the trachea presented a good long-term outcome.
