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.

Seventeen patients with small cell carcinoma of the lung diagnosed on sputum cytology, bronchial biopsy/aspirate or lymph node biopsy, were prospectively followed up for 33 months. Four patients who had no or inadequate treatment survived an average of 10.5 months. Ten treated patients survived 10.6 months. Three patients are still alive receiving chemotherapy with no local irradiation. All patients were Chinese; all smoked cigarettes; two patients were women; all patients were older than 50 years. Four patients had no chest complaints but presented with Superior Vena Caval obstruction (two cases), dermatomyositis and the Eaton Lambert syndrome. Two patients had the syndrome of inappropriate antidiuretic hormone secretion. None was hypercalcaemic. Twelve patients had right sided lung lesions. The majority of patients underwent combined radiotherapy and chemotherapy, the latter consisting of three weekly cyclical methotrexate, adriamycin, cyclophosphamide and CCNU (MACC regime).

A 68-year-old man was admitted to our hospital because of muscle weakness. A complete medical examination led to a diagnosis of small cell lung carcinoma (SCLC) with Lambert-Eaton myasthenic syndrome (LEMS) and the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Four courses of chemotherapy (carboplatin + etoposide) and one of radiotherapy with a total dose of 45 Gy to the mediastinum were performed and resulted in a partial response in the SCLC. After the second course of chemotherapy, the serum level of antivoltage-gated Ca2+ channel (VGCC) antibody decreased from 190 pg/ml to 120 pg/ml. Marked improvement of the muscle weakness was recognized only after 3 courses of chemotherapy. The patient, who had had difficulty in standing, recovered enough to be able to climb stairs after 4 courses of chemotherapy. Marked improvement of LEMS was achieved by treatment for small cell lung carcinoma.

The objective of this study was to present some clinical and radiological manifestations of PNS in relation to bronchogenic carcinoma (BC) and to evaluate the usefulness of imaging findings in the diagnosis of asymptomatic BC. In the study group of 204 patients (146 male and 58 female) with proven bronchogenic carcinoma, PNS was present in 18 (8.62%) patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2%) patients with symptoms related to primary tumours while the second one consisted of 5 (27.7%) patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma), a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma), a case of Cushing Syndrome (small-cell carcinoma), and hypercalcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO) were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an indicator of a higher likelihood of metastatic disease.

Small cell lung cancer accounts for approximately 15% of bronchogenic carcinomas. It is the cancer most commonly associated with various paraneoplastic syndromes, including the syndrome of inappropriate antidiuretic hormone secretion, paraneoplastic cerebellar degeneration, and Lambert-Eaton myasthenic syndrome. Because of the high propensity of small cell lung cancer to metastasize early, surgery has a limited role as primary therapy. Although the disease is highly sensitive to chemotherapy and radiation, cure is difficult to achieve. The combination of platinum and etoposide is the accepted standard chemotherapeutic regimen. It is also the accepted standard therapy in combination with thoracic radiotherapy (TRT) for limited-stage disease. Adding TRT increases absolute survival by approximately 5% over chemotherapy alone. Thoracic radiotherapy administered concurrently with chemotherapy is more efficacious than sequential therapy. Furthermore, the survival benefit is greater if TRT is given early rather than late in the course of chemotherapy. Regardless of disease stage, no relevant survival benefit results from increased chemotherapy dose intensity or dose density, altered mode of administration (eg, alternating or sequential administration) of various chemotherapeutic agents, or maintenance chemotherapy. Prophylactic cranial radiation prevents central nervous system recurrence and can improve survival. In Japan and some other Asian countries, the combination of irinotecan and cisplatin is the standard chemotherapeutic regimen. Clinical trials using thalidomide, gefitinib, imatinib, temsirolimus, and farnesyltransferase inhibitors have not shown clinical benefit. Other novel agents such as bevacizumab have shown promising early results and are being evaluated in larger trials.

Although the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and Lambert-Eaton myasthenic syndrome (LEMS) are often individually accompanied by small-cell lung carcinoma, simultaneous occurrence of the 2 syndromes is rare. A 61-year-old man was admitted to our hospital because of fatigue and myasthenia in the extremities, and small-cell lung carcinoma with pulmonary metastasis was diagnosed, together with SIADH and LEMS. These syndromes markedly ameliorated following tumor shrinkage, with 4 cycles of chemotherapy consisting of carboplatin and etoposide. On progression of the tumor thereafter, neither syndrome recurred. A literature review disclosed that these syndromes frequently resolve with tumor shrinkage.
