Abstract
Background Colorectal cancer (CRC) incidence in Finland has risen steadily. Given development in cancer treatments in recent decades, disease-specific data on the long-term prognosis of patients may be obsolete. Thus, this study aimed to report 5-year disease-specific survival (DSS) and relative survival based on tumour spread and site among CRC patients diagnosed between 1991 and 2015 in Finland. Material and methods We conducted a population-based registry study among 59 465 CRC patients identified from the Finnish Cancer Registry. Results The 5-year DSS for all CRC patients was 56.7% [95% confidence interval (CI) 56.3–57.1%] for 1991 through 2015. Tumour site-specific survival has improved for the period 2006–2015 versus 1991–2005 for right-sided colon cancer from 54.8% (95% CI 53.8–55.8%) to 59.9% (95% CI 58.7–61.1%), for left-sided colon cancer from 54.1% (95% CI 52.9–55.3%) to 61.0% (95% CI 59.8–62.2%) and for rectal cancer from 53.6% (95% CI 52.2–55.0%) to 62.3% (95% CI 61.3–63.3%). The 5-year relative survival for the period 2006 through 2015 was 93.6% for localised disease (stage I); 84.2% for locally advanced tumour invading adjacent structures (stage II); 68.2% for regional disease with regional lymph node metastases (stage III); and 14.0% for metastatic disease (stage IV). Conclusions This study confirms that survival for CRC has improved in recent decades in Finland, mirroring observations from other Western countries. However, the classification of tumour spread within the Finnish Cancer Registry differs slightly from the TNM classification, thereby limiting the generalisability of these results.

Colorectal Dis 2020; 22:1108-1118. [PMID: 32012414 DOI: 10.1111/codi.14999] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 12/15/2019] [Indexed: 02/08/2023]
Abstract
AIM An anastomotic leak after surgery for colon cancer is a recognized complication but how it may adversely affect long-term survival is less clear because data are scarce. The aim of the study was to investigate the long-term impact of Grade C anastomotic leak in a large, population-based cohort. METHOD Data on patients undergoing resection for Stage I-III colon cancer between 2008 and 2012 were collected from the Swedish, Norwegian and Danish Colorectal Cancer Registries. Overall relative survival and conditional 5-year relative survival, under the condition of surviving 1 year, were calculated for all patients and stratified by stage of disease. RESULTS A total of 22 985 patients were analysed. Anastomotic leak occurred in 849 patients (3.7%). Five-year relative survival in patients with anastomotic leak was 64.7% compared with 87.0% for patients with no leak (P < 0.001). Five-year relative survival among the patients who survived the first year was 88.6% vs 81.3% (P = 0.003). Stratification by cancer stage showed that anastomotic leak was significantly associated with decreased relative survival in patients with Stage III disease (P = 0.001), but not in patients with Stage I or II (P = 0.950 and 0.247, respectively). CONCLUSION Anastomotic leak after surgery for Stage III colon cancer was associated with significantly decreased long-term relative survival.
