A clinicopathologic analysis of chronic lymphocytic leukemia.

Sixty consecutive patients with chronic lymphocytic leukemia (CLL) were studied from both a clinical and laboratory standpoint. Hypoimmunoglobulinemia was found in 45% of patients; many of these patients suffered from severe bacterial infections. Second primary malignancies were diagnosed in 20% of patient's; most of these predated the diagnosis of CLL.

Serum glycoprotein hormone alpha subunit levels in patients with cancer.

The serum glycoprotein hormone alpha subunit concentration was measured in 957 nonpregnant patients with benign disorders and 683 patients with unselected malignancies. Postmenopausal women had significantly higher alpha levels than premenopausal women or men. When the patients were subdivided according to age, sex or disease sites, significant population differences were found for women less than 50 years of age and patients with cancers of presumed neural crest origin.
