Blood lymphocytes from 47 patients with lung carcinoma have been tested for cytotoxicity against cells isolated from the autologous tumour. Significant cytotoxic potential was found in 15 cases. The effectors were also tested against allogeneic tumour targets from lung and other sites. Reactions were only rarely detected (2/32 positive against lung and 1/13 positive against non-lung cells). The restriction of cytotoxicity to the autologous combination was also apparent in in vitro-generated effectors. Blood lymphocytes were co-cultivated with autologous tumour and subsequently tested against autologous or allogeneic targets. Cytotoxicity was found in 13/17 lung tumours against autologous tumour, with no reactions recorded against allogeneic tumour targets, but one case positive against the K562 cell line. These data suggest either the expression of individually distinct antigens on human pulmonary neoplasms, or the requirement for histocompatibility between target and effector in cytotoxicity reactions in man, and therefore differ from previously described patterns of lymphocytotoxicity against human tumours.

Serum levels of carcino-embryonic antigen (CEA) and beta2-microglobulin (beta2m) were assayed on 133 sera during follow-up of 31 patients with lung carcinoma (squamous cell ca. without recurrence : 2, squamous cell ca. with recurrence : 11, anaplastic cell ca. : 4, adenocarcinoma : 2, unclassifiable : 5). Normal creatinine (less than or equal to 12 mg/l) levels were found in all sera. CEA and beta2m levels showed no correlation nor in these groups, nor in the whole. The squamous cell carcinomas with recurrence showed the largest dispersion for CEA as for beta2m levels. However, the trends of serial beta2m values did not correlate with clinical features. Increasing or decreasing levels of CEA and beta2m levels showed no correlation in the whole nor in patients undergoing radiotherapy. In our experience, beta2m levels failed to correlate with clinical findings during the follow-up of lung cancer patients.

Serum beta2-microglobulin levels, determined in 29 healthy adults were found to be 1,3 mg/l with an upper confidence limit (95%) of 2,0 mg/ml. In contrast, serum values in 101 patients with pulmonary tuberculosis were 2,1 mg/l with an upper confidence limit of 3,2 mg/l. The latter value is therefore to be taken into consideration if serum beta2m is to be used for discriminating between lung carcinoma and other pulmonary diseases.

The antitumour activity of the alkaloid thaliblastine was studied on 7 ascitic and solid transplantable tumours in mice. It was found that the compound has a pronounced antitumour effect on ascitic tumour of Ehrlich, NK/Ly lymphoma (i.p.), sarcoma 37 (s.c. and i.p.), sarcoma 180 (s.c.) and Lewis lung carcinoma (i.m.). With a number of tumours, it was found that the single and intermittent drug administration exerts a better therapeutic effect than the chronic treatment.

Lymphocyte proliferation (LP) assays were performed in microculture using the T-cell mitogens phytohemagglutinin (PHA) and concanavalin A (Con A); the T + B cell mitogens, pokeweed mitogen (PWM) and staphylococcal phage lysate (SPL); and a pool of allogeneic stimulating leukocytes in one-way mixed leukocyte cultures (MLC) in lung and breast cancer patients and normal individuals. The resultant data were expressed in three different ways: (1) as mean counts per minute (CPM) of tritiated thymidine incorporation; (2) as a stimulation index (SI) and (3) as a relative proliferation index (RPI). The RPI is defined as the ratio of net CPM (nCPM) in experimental cultures with stimulant (E) minus medium control cultures (C) of a test individual to the mean nCPM of three or more normal individuals examined in the same assay on the same day. These expressions were then compared for their ability to discriminate between LP responses in cancer patients and normal individuals. The RPI value and selected cut-off values gave the most sensitive measure for the determination of depressed proliferative responses. These analyses demonstrated that lung carcinoma patients were depressed to PHA (50%), MLC (47%), PWM (43%) and Con A (40%). To a lesser degree, breast carcinoma patients were also depressed to MLC (36%), PHA (31%), PWM (27%) and Con A (19%). Our data indicate that the use of the RPI in the analysis of LP response represents an improved method for detecting impaired response of lymphocytes to general mitogens and alloantigens which can consistently reveal immunosuppression in many cancer patients and may be useful for serial monitoring of individual patients.

A patient who died from oat-cell carcinoma of the lung had had abdominal pain and obstipation. Autopsy revealed autonomic neuropathy limited to the gastrointestinal tract, which was considered to be related to carcinoma as a remote effect. This interpretation was further supported by the presence of Wallerian degeneration of the dorsal columns. Autonomic neuropathy involving the gastrointestinal tract in association with malignant disease has not been previously described.

Hypercalcemia is very uncommon in small cell (oat cell) carcinoma of the lung. Two cases of this neoplasm associated with symptomatic hypercalcemia are described. Despite normal skeletal roentgenograms, metastatic bone disease was demonstrated by abnormal bone scans and bone biopsies in both patients. The combination of conventional antihypercalcemia therapy, cytotoxic cancer chemotherapy, and synthetic salmon calcitonin corrected the hypercalcemia despite progression of the small cell carcinoma. One patient with elevated serum immunoreactive parathyroid hormone (PTH) had a parathyroid adenoma at autopsy. This association emphasizes that in cases of bronchogenic small cell carcinoma with hypercalcemia, conincidental primary hyperparathyroidism should be considered.

A chemotherapeutic regimen consisting of BCNU, cyclophosphamide, vincristine, and procarbazine was evaluated in 43 patients with small cell carcinoma of the lung. The majority of patients received radiation therapy of the primary tumor, but chemotherapy alone was utilized in a group of patients with widely disseminated disease. In addition to thorough staging with radioisotope scans and bone marrow biopsies, a study of calcitonin and histaminase as biochemical markers was performed. The BCVP chemotherapy resulted in a complete and partial response rate of 53% when given alone or in conjunction with radiotherapy. The survival data are preliminary, but the complete responders do have a statistically significant better survival (mean of + -95 days) than the partial responders and nonresponders. Hypercalcitonemia was not detected in our patients, but elevated histaminase activity was found in eight of 24 patients with small cell carcinoma and in only one of 19 patients with squamous and large cell carcinoma.

Three thousand patients with primary carcinoma of the lung entered in the Armed Forces Central Medical Registry are reported. Forty-one per cent had squamous cell, 28.5 per cent adenocarcinoma, 25.2 per cent small cell/undifferentiated, and 4.9 per cent miscellaneous cell types. When first seen, 71.1 per cent had no organ metastases and 50.6 per cent no lymph node metastases. Over-all survival rate was 18.2 per cent at 5 years and 14.5 per cent at 10 years. Survival following definitive resection, palliative resection, definitive radiation, palliative radiation, and chemotherapy was determined both in the presence of mediastinal nodal involvement and in the absence of mediatinal nodal involvement. Where resection for cure could be carried out, 5 year survival rates of 48.8 per cent were possible. The factors affecting this improved outlook in our military population are discussed and, in general, appear to be related to a ready accessibility of medical care and the necessity, because of global commitments, of establishing an early diagnosis. Cell type ecerted some influence on survival, but the major determinant appeared to be the absence of involved nodes at the time of the operation.

Clinical evaluation of 10 patients with small cell carcinoma of the lung treated with radiotherapy and periodic cycles of combination chemotherapy with cyclophosphamide, vincristine, and adriamycin showed frequent and occasionally severe esophageal and skin reactions. Eight of the 10 patients had esophagitis, four required supportive intravenous fluids, and two subsequently developed esophageal narrowing and stricture formation. Recurrent esophagitis with augmentation of injury in the recently irradiated esophagus was observed 11 times in eight of the 10 patients after cycles of chemotherapy, and contributed to the sustained toxicity seen in two patients. Dermatitis in the form of moist desquamation was observed in five of the patients at very low doses of supervoltage radiation therapy. Acute pulmonary reactions was notably absent. This combination of chemotherapy, particularly adriamycin, potentiates the effect of radiotherapy on the normal esophagus and skin, and further implicates the radiosensitizing property of adriamycin.
