Abstract

Objective

To describe the trends over calendar period and birth cohort in lung cancer incidence by histopathology and sex, in Alberta.

Methods

Lung cancer data were extracted from the Alberta Cancer Registry for the years 1979 to 1998. Trends in age-standardized rates over calendar period and trends of age-specific rates over birth cohorts are presented. These trends are discussed in relation to historic smoking patterns.

Results

Lung cancer incidence is increasing over calendar period in females for all lung cancers and the histological types, adenocarcinoma, squamous cell, and small cell carcinoma. In males, all lung cancer incidence increases until 1988 and then decreases. Adenocarcinoma incidence in males increases over the whole time period, while squamous cell and small cell carcinoma incidence decreases. For females born before 1939, the incidence of all lung cancer and the three histological types increases over birth cohorts for all age groups. For those born after 1939, there is a slight decline. Male lung cancer incidence shows no marked increases over birth cohorts. In males born after 1929, all lung cancer and squamous cell and small cell carcinoma incidence decreases over birth cohorts for all age groups. Incidence of adenocarcinoma increases over all birth cohorts in males.

Conclusion

In Alberta, incidence of adenocarcinoma of the lung is increasing in both males and females, while squamous cell and small cell carcinoma are decreasing in males, but increasing in females. These trends may reflect changes in smoking habits.

Résumé

Objectif

Décrire les tendances de l’incidence du cancer du poumon en Alberta selon l’histopathologie et le sexe, par période du calendrier et par cohorte de naissance.

Méthode

Les données sur le cancer du poumon sont extraites du Alberta Cancer Registry (1979 à 1998). Les tendances des taux sans strate d’âges (présentées par période du calendrier) et les tendances des taux par âge (présentées par cohorte de naissance) sont analysées selon les schémas historiques du tabagisme.

Résultats

L’incidence du cancer du poumon par période du calendrier est en hausse chez les femmes pour tous les types de cancers du poumon et pour les types histologiques adénocarcinome, carcinome spinocellulaire et carcinome à petites cellules. Chez les hommes, l’incidence de tous les cancers du poumon s’accroît jusqu’en 1988 et diminue par la suite. L’incidence des adénocarcinomes chez les hommes augmente pour l’ensemble de la période, mais l’incidence des carcinomes spinocellulaires et à petites cellules diminue. Chez les femmes nées avant 1939, l’incidence par cohorte de naissance de tous les cancers du poumon et des trois types histologiques augmente pour tous les groupes d’âge. Chez les femmes nées après 1939, les taux diminuent légèrement. Globalement, l’incidence du cancer du poumon chez les hommes ne présente aucune augmentation marquée par cohorte de naissance, mais l’incidence des adénocarcinomes augmente pour toutes les cohortes de naissance, et, chez les hommes nés après 1929, l’incidence par cohorte de naissance de tous les cancers du poumon, des carcinomes spinocellulaires et des carcinomes à petites cellules diminue pour tous les groupes d’âge.

Conclusion

En Alberta, l’incidence des adénocarcinomes du poumon est en hausse tant chez les hommes que chez les femmes, tandis que l’incidence des carcinomes spinocellulaires et des carcinomes à petites cellules diminue chez les hommes, mais augmente chez les femmes. Ces tendances sont peut-être liées à l’évolution des habitudes de tabagisme.
