ABSTRACT: The correct examination of lymph nodes is decisive for tumour classification into stage 2 and stage 3. The aim of this specialised population-based study was to investigate the influence of clinical factors and volume of surgical activity on lymph node assessment in France for patients diagnosed with localised colorectal cancer.
From 1997 to 2004, French digestive cancer registries recorded a total of 4197 cases of colorectal cancer. The volume of surgical activity was appreciated by the annual number of digestive surgery admissions in 2004. The probability of having at least 12 lymph nodes examined after surgical resection was analysed using a multilevel logistic regression model.
Only 1900 patients had more than 12 lymph nodes examined (45.2%). The percentage of patients with at least 12 lymph nodes examined after tumour resection is directly associated with the volume of surgical activity within care centres for patients diagnosed between 1997 and 2000. This association was no longer significant during the second period study (2001-2004).
This population-based study reports that only 55% of colorectal patients have a sufficient number of lymph nodes examined. This insufficient number of examined lymph nodes could be considered as a potential prospect for increasing treatment quality in cancer patients in France.
