Occurrence of malignant neoplasms in patients with chronic lymphatic leukaemia.
In a group of 280 patients with chronic lymphatic leukaemia, a coexistence of malignant tumours diagnosed simultaneously with the leukaemia was found in 14 cases or 5.0%. No significant difference was observed between the development of the second malignant neoplasm in the patients studied and the expected incidence in the general population, taking into account also the sex and age of patients and their place of residence. No statistically significant relation was found between the duration of CLL and the occurrence of second malignancies. No significant correlation was found between the total dose of cytostatic drugs, corticosteroids or radiotherapy and the incidence of cancer.
