The urinary excretion of nonesterified cholesterol (NEC) in 170 women with cervical and endometrial carcinomas has been investigated. Control patients (236) included: 1) women with other types of benign and/or malignant diseases of the pelvic organs; 2) patients with non‐steroid‐related neoplasms; 3) patients with benign and/or malignant breast diseases other than carcinoma; and 4) patients with a variety of non‐neoplastic diseases. NEC was determined by a gas‐liquid chromatographic procedure. The range of NEC excretion for clinically healthy normal women (64) was previously established by this method. NEC hyperexcretion was defined as any NEC value over 1.5 mg/24 hours. The results showed NEC hyperexcretion in 65 of 68 women with active carcinoma of the cervix, including 13 patients with carcinoma in situ, and in 42 of 45 women with active carcinoma of the endometrium. In contrast, a normal excretion of NEC occurred in all the patients (77) of the first and second control groups, in 39 (80%) of the 48 patients of the third control group (high‐risk group), and in 101 of the 111 patients of the fourth control group. Sequential studies performed in patients with uterine carcinomas have demonstrated an almost perfect correlation between the NEC excretion and the clinical status of the patient following surgical and/or radiation therapy. Of 57 patients (31 cervix and 26 endometrium) in which the NEC studies were started after treatment was instituted, 53 have normal NEC excretion in the multiple determinations performed to date. Presently these patients have no clinical, chemical, or radiologic evidence of cancer. It is concluded that urinary NEC determinations can be used as an additional diagnostic biochemical test to detect active carcinoma of the steroid‐producing glands and their main target organs, and that in women with uterine carcinomas, the test can be used as an objective laboratory method to monitor the course of the disease and the response of the patient to therapy.
