The relation of hypercalcemia, histologic cell type, and osseous neoplastic involvement was studied in 200 consecutive patients with untreated bronchogenic carcinoma. The overall frequency of hypercalcemia was 12.5%. Twenty-three percent of patients with epidermoid carcinoma, 12.7% with large-cell anaplastic carcinoma, 2.5% with adenocarcinoma, and none with small-cell carcinoma presented with or developed hypercalcemia. Fourteen of 25 patients (56%) with elevated calcium did not have osseous metastases. Osseous involvement was most frequently observed in patients with small-cell carcinoma (66%) and adenocarcinoma (50%). The data indicate that hypercalcemia is predominantly associated with epidermoid and large-cell anaplastic carcinoma and uncommonly associated with adenocarcinoma and small-cell carcinoma, even though the latter two cell types are most frequently associated with osseous metastases.
