title: [Incidence of malignant lymphomas in Western Maritime Provinces in the years 1980-1984].
abstract: Incidence rate of malignant lymphomas was determined in the population of Western Pomerania region. The period of studies covered the years from 1980 to 1984 and the patients being over 14 years old. In the Western Pomerania region malignant lymphoma was diagnosed during that period in 528 subjects: low grade malignancy lymphomas were diagnosed in 268, therein lymphocytic lymphomas 135, with high grade malignancy 54: malignant granulomatosis 125 cases and 77 plasmocytic myelomas. The following data were taken into consideration: sex, place of residence, type of lymphoma: in case of malignant granulomatosis also the histopathologic subtype, and in multiple myeloma the type of monoclonal protein. Szczecin Voivodeship was found to have the highest incidence rate of malignant lymphoma, namely 9,1/10(5) of inhabitants: in Koszalin and Gorzów Voivodeships respectively 6.9/10(5) and 6.1/10(5) of inhabitants annually. The difference in the incidence rate in Szczecin Voivodeship and two other ones was significant (p < 0.001). No significant differences in the morbidity existed between Koszalin and Gorzów Voivodeships. In the region there was a preporderance of malignant lymphomas in relation to malignant granulomatosis. Morbidity in malignant lymphoma more frequently involved men than women. Morbidity rate of lymphoma with low and high malignancy, as well as plasmocytic myeloma increases with the age. On the other hand, in malignant granulomatosis no statistically significant differences depending on the age and sex were recorded. The incidence rate in respective groups of malignant lymphoma was the highest in Szczecin, followed by other towns in the region, being the lowest in rural environment. In our region, with regard to all malignant lymphomas, the disease is more frequently diagnosed in the advanced clinical stage.
