To elucidate the ectopic hormonal pattern in patients with small cell carcinoma of the lung, plasma ACTH, serum calcitonin, serum gastrin, plasma glucagon, serum insulin, plasma secretin, plasma VIP, serum growth hormone, serum hCG/LH, the total of serum hCG and hCG-beta-subunit,serum alpha-subunit, serum human placental lactogen, urine ADH, urine 5-HIAA, urine VMA, urine HVA, and urine hCG-LH were measured prior to therapy in 75 patients. Twenty-two patients (29%) had elevated plasma ACTH, and 18 of these had concomitant increased values of corticosteroid in a 24-hour urine sample. Forty-eight patients (64%) were found to have elevated serum calcitonin, and one-third of the patients were diagnosed as having the ectopic ADH syndrome. Serum gastrin concentrations were increased in 20% of the patients, but the elevations were marginal in almost all cases. None of the remaining substances was found to be significantly elevated. Concentrations of plasma ACTH, serum calcitonin, and urine ADH were not found to be correlated with the stage of the disease, and no correlation of these substances with the histological subtypes of small cell carcinoma was disclosed.

Continuous cell lines have been established from a variety of biopsy and postmortem species of tumor from patients with small-cell carcinoma of the lung (SCCL) and have been maintained over several years. The medium from the cultures has been assayed for peptide, glycoprotein, and steroid hormones. Significant amounts of 14 hormones including calcitonin, adrenocorticotropin (ACTH), parathormone, luteinizing hormone, chorionic gonadotropin, glucagon, growth hormone, somatostatin, prolactin, beta-endorpin, lipotropin, oxytocin-neurophysin, vasopressin-neurophysin, and estradiol have been demonstrated. Up to ten different hormones have been produced by a single cell line. Most produce ACTH and all evaluated so far produce estradiol. These studies indicate that cells from SCCL have a potential for producing a wide variety of hormones and that this characteristic can be maintained for prolonged periods of culture in vitro.

After 4-6 months in continuous culture the human small cell lung cancer (SCLC) cell line, U-1906, changed its radiobiological characteristics spontaneously. The cell line became more radioresistant indicating an increased repair capacity. This change was accompanied by a more adherent growth pattern, a higher clonogeneity, a decrease in the cytokeratin (tissue polypeptide antigen) content and increased glucagon and neuron-specific enolase (NSE) production. Other parameters such as the estramustine-binding protein (EMBP) and the proliferation associated antigen Ki-67 were unaltered. This spontaneous transformation in vitro of U-1906 may reflect a clinically important in vivo phenomenon of SCLC, which frequently develops resistance both to radio- and chemotherapy.
