Inappropriate secretion of antidiuretic hormone or Schwartz-Bartter syndrome is considered to be a paraneoplastic endocrine syndrome, most frequently associated with a small cell anaplastic carcinoma of the lung. The authors present a case of sub-glottal laryngeal carcinoma discovered several months after the onset of clinical (disturbances of conscious level) and laboratory (hyponatraemia, hypochloraemia, blood hypo-osmolarity which preservation of urinary sodium output) manifestations which form the original features of this syndrome, the criteria of which are reviewed. The y conclude by the need for complete examination, not excluding unusual sites of primary tumour.

In 2 patients with the nephrotic syndrome, unsuspected solid tumors were found. One was a small cell lung carcinoma, accompanied with the syndrome of inappropriate ADH secretion. The other was a cancer of the breast with lymph node and bone metastases. In both, renal biopsy showed minimal change disease without immune complex deposits. There are only 14 other reported cases of paraneoplastic lipoid nephrosis complicating solid tumors. Such cases lead to the discussion on the respective roles of tumor cell gene product(s) inducing proteinuria and of lymphokine secretion by lymphocytes directed against the tumor itself. Cancer should be considered as a possible etiology of the minimal change nephrotic syndrome in the adult.

A patient with small cell carcinoma of the lung developed asymptomatic autonomic neuropathy, inappropriate antidiuretic hormone (ADH) secretion and Lambert Eaton myasthenic syndrome. The autonomic neuropathy and inappropriate ADH secretion were present at the time of diagnosis of the tumour. Following chemotherapy these resolved, but 5 months later the patient developed Lambert Eaton syndrome which responded to 3,4-diaminopyridine. This sequence of changes appears to be unique.

The ectopically produced polypeptide hormones ACTH, ADH, and calcitonin were investigated as tumor markers in patients with small-cell carcinoma of the lung (SCC). Plasma ADH concentrations were evaluated separately as well as in relation to concomitantly obtained plasma osmolality levels. No significant nor consistent changes of marker concentrations caused by lysis of tumor cells were found immediately after administration of cytotoxic drugs. After tumor regression, plasma ACTH and serum calcitonin concentrations and inappropriate ADH secretion (plasma ADH levels inappropriately high compared with plasma osmolality) became normal in most cases; however, progressive disease was not followed consistently by changes in plasma ACTH concentrations and occurrence of inappropriate ADH secretion. Contrary to this, among 12 patients with disease progression, serum calcitonin levels increased in ten patients and plasma ADH levels increased in 11 patients. In most cases, however, these changes were only moderate, and serum calcitonin concentrations were found to be increased after tumor regression in patients who had normal pretreatment levels. It is concluded that decisions on treatment of patients with SCC cannot exclusively be based on changes in the concentrations of the polypeptide hormones that might be of ectopic origin.

Eighty-four patients with small cell carcinoma of the lung were reviewed with respect to the frequency and biologic behavior of patients with a demonstrated ectopic hormone syndrome. This subgroup of 12 patients (14%) was compared with regard to stage of disease, distribution of metastases, response rate, and survival to those patients not demonstrating a clinical syndrome. Stage, distribution, and response rates are comparable in the two groups but differences were observed with regard to sites of metastases and survival. The ectopic hormone syndrome patients had an increased likelihood of liver metastasis and CNS metastasis. The frequency of CNS metastasis in patients without the ectopic hormone syndrome was 11/72 (15%) of which four of the 11 were present at initial presentation. In contrast, 5/12 (42%) of the patients with ectopic hormone syndromes developed CNS metastasis, and all five had clinically demonstrated SIADH. Survival was consistently inferior in those patients with the ectopic hormone syndrome.

From 1976 to 1980, 18 of the 250 patients (7%) seen with small cell carcinoma of the lung had clinically evident inappropriate secretion of antidiuretic hormone (ADH). Hyponatremia was usually severe (116 +/- 7 meq/l), and eight patients showed symptoms of water intoxication at the time of diagnosis. Of the eight patients who had plasma ADH measured at diagnosis, seven had elevated values (mean 52.0, range 16.1 - greater than 250 pg/ml). Intensive combination chemotherapy produced objective tumor responses in all patients, and syndrome of inappropriate ADH secretion (SIADH) resolved in 16 of 17 evaluable patients within three weeks of initiation of treatment. ADH values after therapy were normal, and all patients maintained a normal serum sodium during the period of tumor remission in spite of unrestricted fluid intake. All 17 evaluable patients have developed progressive cancer, but only 10 have manifested recurrent SIADH. Patient survival was similar to the overall population of small cell carcinoma patients without SIADH. The indirect methods of treatment for SIADH (fluid restriction, demeclocycline, lithium, urea) are frequently of transient value while awaiting a response to chemotherapy or in patients with resistant tumors. However, the initial treatment of choice for SIADH associated with small cell carcinoma of the lung is combination chemotherapy.

An electron microscopic study of 28 small cell carcinomas of the lung is presented. Cytoplasmic secretory granules, characteristic of endocrine cells of the human foetal lung were observed in a variable number of tumor cells. Two groups of tumors could be distinguished based on the morphology of the cytoplasmic secretory granules. Twenty-three tumors showed cells with granules resembling type 1 or P1 cells of the human fetal lung, and 5 tumors with granules resembling type 3 cells of the human fetal lung. No relationship was found between the light microscopic WHO classification of small cell carcinoma of the lung and the results obtained by electron microscopy. Increased serum calcitonin as well as inappropriate ADH secretion may be correlated with one of the two types of small cell carcinoma, but further investigations are needed.

The very rare occurrence of an ADH-producing small cell carcinoma of the lung in a 52 year old male patient with cranial diabetes insipidus since childhood is described. In this case diabetes insipidus disappeared concomitantly with development of lung cancer and re-appeared with shrinkage of the lung tumour by radiation therapy. Further progressive expansion of the primary and metastatic tumours induced the syndrome of inappropriate ADH secretion once again (SIADH). This deterioration in the clinical course was reflected in the plasma levels of ADH and neurophysins. The existence of vasopressin in the tumour tissue was also demonstrated by means of an immunohistochemical staining technique combined with anti-vasopressin serum.

A 54-year-old woman underwent a left upper lobectomy for lung carcinoma after which hyponatremia developed within 5 days. Her serum concentration of ADH was within normal range disapproving the presence of SIADH frequently associated with lung carcinoma. An endocrinological examination showed panhypopituitarism. From her anamnesis it was seen that there was much perinatal bleeding and amenorrhea. She was diagnosed as suffering from Sheehan syndrome. She was treated with glucocorticoid and beneficial results were obtained. Her serum concentration of natrium returned to normal and she discharged on the 74th postoperative day. We present this paper because we had difficulty in determining that she had Sheehan syndrome, and think that a careful search for a diagnosis before operation is important for the management of the patient during the perioperative and postoperative period.

Adrenal carcinoma is a malignant disease that often results in distant metastases to different organs, including the lungs. While diagnosing patients with suspected adrenal carcinoma, metastases to the lungs should always be considered. The opposite clinical situation also should be considered, i.e. lung cancer metastases to the adrenal gland. Both conditions may have a very similar course and their differential diagnosis may be sometimes very difficult. However, proper diagnosis is of great importance because both diseases are treated by different means. We present a case of a 50-year-old female patient with a small primary focus of non-small cell lung carcinoma and its large metastasis to the left adrenal gland, accompanied by SIADH and paraneoplastic hypercalcemia. In the presented case adrenal carcinoma and its lung metastasis were primarily misdiagnosed which led to unnecessary laparotomy. The proper diagnosis was enabled by CT guided biopsy of the lung tumor.
