[Epidemiology and incidence of primary lung cancer in a region with low tobacco consumption: Guadeloupe (French West Indies). Data from the cancer registry 2008-2009].

INTRODUCTION

Few data are available about primary lung cancer in the Caribbean. The purpose of this study was to provide, for the first time, the epidemiological and clinical characteristics of primary lung cancer in the archipelago of Guadeloupe (French West Indies).

METHODS

From the cancer registry, we identified in this retrospective study, all incident cases of primary lung cancer that had occurred between 1st January 2008 and 31st December 2009 in Guadeloupe.

RESULTS

Over the period from 2008 to 2009, 106 patients with primary lung cancer were identified. Males accounted for 72.6% and the women for 27.4%. Mean incidence rate over the 2 years was estimated at 13.4/100000 persons-years (95% CI: [6.0-20.8]) in men (world standardized) and 4.2/100000 persons-years (95% CI: [0.3-8.1]) in women. The median age at initial diagnosis was 65 years for men and 66 years for women. We noted a proportion of 61.3% of current smokers, 4.7% of passive smokers and 34% of non-smokers. The comorbidities were present in 41% of patients. Non-small cell lung cancer (NSCLC) accounted for 88.7% of lung cancers and small cell lung cancer for 7.5%. The most common histological type was adenocarcinoma (43%) followed by squamous cell (24%). Stage III and IV patients accounted for 64.1% of individuals with NSCLC.

CONCLUSION

The incidence of primary lung cancer in Guadeloupe is relatively low compared to metropolitan France. Guadeloupe is also a French department where the rate of tobacco consumption is one of the lowest.
