title: Relationship between epidemiologic and endocrinologic aspects of cervical cancer.
abstract: In search of etiologic relevancy of the steroid deviations in urine, we compared the reproductive activities of patients having cervical cancer with those of normal controls. A premenopausal patient experienced the birth of her first child significantly earlier than did the urban control of corresponding age, despite their similarity of age at menarche. However, when the same patient was compared with the premenopausal rural control, this differences was not found. The same parameter also failed to differentiate a postmenopausal patient from the corresponding control of urban origin. The premenopausal patient who was indistinguishable from the rural control by age at first delivery was distinguished from the rural control by reduced excretions of adrenal steroids including 11-deoxy-17 ketosteroids and some corticosteroid metabolites. The spectrum and the degree of deviation of urinary steroids for a patient coincided with the spectrum and the degree of age dependency of the urinary steroids for a normal woman during and after adolescence. These findings indicated that the inability of the reproductive parameter to discriminate a patient was associated with growth retardation in a population, and a maturation deficiency of the adrenal gland (arrest of adrenarche) was implicated in the genesis of cervical cancer.
