[Hypercalcemia in bronchogenic carcinoma]

In a population of 621 patients with morphologically proven bronchogenic carcinoma the rate of hypercalcaemia in particular morphologic types of bronchogenic carcinoma was ascertained during the establishment of diagnosis. Regardless of type, there were 10.3% of hypercalcaemic patients in the whole population. Hypercalcaemia was found most frequently in epidermoid carcinoma (10.98%), followed by adenocarcinoma (10.51%), small cell carcinoma (10.11%) and undifferentiated carcinoma (9.72%). In the group of 19 large cell carcinomas the hypercalcaemia was not established. Except large cell carcinoma, the differences among the groups were not statistically significant.
