J. Peng et al., AN EPIDEMIOLOGIC AND SURVIVAL STUDY OF GA STRIC-CARCINOMA IN THE SOMME AREA OF FRANCE BETWEEN 1987 AND 1990, Annales de Gastroenterologie et d'Hepatologie, 34(1), 1998, pp. 23-28
Objectives: to determine the characteristics of gastric carcinomas dia
gnosed between 1987 and 1990 in the Somme area of France. Methods: The
study was based on cancer registry data. During the study period, 301
cases of gastric carcinoma, including 255 of gastric adenocarcinoma,
were identified, in 160 men and 95 women. Incidence rates were calcula
ted. Relative survival rates were estimated using the J. Esteve method
and compared using Cox models. Results: Crude incidence rates were 21
.5/100 000 in men and 9.3/100 000 in women. Only 15.7 of tumors did no
t extend beyond the muscle layer. Surgical excision was performed in 1
27 cases (49.8%), chemotherapy in 12 cases (4.7%), and radiation thera
py in two cases (0.8%). Overall five year survival was 13%. A multivar
iate analysis of the surgically-treated tumors identified four factors
with a significant bearing on survival, namely invasion of the resect
ion margin, invasion of lymph nodes, metastases to internal organs, an
d invasion of the wall. Conclusion :The diagnosis of gastric carcinoma
in the Somme district was often delayed, the tumors were often not am
enable to therapy, and the overall prognosis was grim.
