Primary gastric non-Hodgkin's lymphoma in a population-based registry.

BACKGROUND: The incidence of primary gastric non-Hodgkin's lymphoma (NHL) appears to have increased worldwide in recent years, and this seems to be confirmed by large-sample population studies. METHODS AND RESULTS: We derived our data from the Lombardy Cancer Registry, which provides the incidence of cancer in the province of Varese, Northern Italy. From 1978 to 1987 we identified 3261 cases of gastric neoplasms, 119 of which were gastric NHL: 32 (1.87%) from 1978 to 1982, and 87 (5.32%) from 1983 to 1987. The difference in the age and sex standardized incidence trend between these two time periods was statistically significant (p < 0.001). The overall survival rate of the 112 evaluable patients was 54% at 5 years and 45% at 10 years. A multivariate analysis was performed. Age (p < 0.0005), clinical stage (p < 0.04) and therapy (p < 0.0005) were found to be significant prognostic factors for survival. CONCLUSIONS: This study stresses the utility of prospective randomized clinical trials that could indicate the optimal management of patients with primary gastric lymphoma.

Validity for epidemiological studies of long-term cryoconservation of steroid and protein hormones in serum and plasma.

Prospective studies based on the storage of biological samples at low temperature have opened new perspectives in etiological research on cancer. In planning these studies a crucial question is to evaluate whether the long-term preservation of samples is able to affect the categorization of the subjects involved. In the frame of the ORDET project, a prospective study of hormones and diet in the etiology of breast cancer provided with a -80 degrees C biological bank, we have evaluated the stability of estradiol, free and total testosterone, and prolactin in serum and plasma samples over 3 years of cryoconservation. Study results showed that the subjects maintained almost the same rank by hormonal concentration throughout the 3-year period for all hormones. Looking at the stability over time, estradiol, prolactin, and total testosterone had fairly good performance for both serum and plasma. Serum-free testosterone increased in time up to 30%, whereas progesterone decreased by about 40% of the initial concentration. However, the reliability of the individual categorization by hormonal level suggests the validity of low temperature storage for epidemiological purposes, at least for hormonal parameters.
