From 1955 to 1975 in 25 patients lung surgery has been carried out because of intrapulmonary metastases of extrapulmonary malignant growth. 6 patients survived longer than 5 years. There was no relationship between survival time and length of the time interval between initial surgery (primary) and second operation (i.e. diagnosis of pulmonary lesion). On the other hand a definite relationship resulted for survival time and the size of the growth. In bad-risk patients surgery for metastatic lung cancer is not indicated, but it is very successful in selected cases.

After surgical resection of their primary lung cancer, 33 patients were randomized into one of three groups. The first received high-dose methotrexate once per month with citrovorum rescue, for 3 months. The second group were immunized monthly with a homogenate of Freund's complete adjuvant and carefully characterized soluble antigen derived from allogeneic lung cancer cells of appropriate histology, for 3 months. The third group received a combination of methotrexate and immunization monthly, for 3 months. Each patient was monitored immunologically before, during, and after the treatment period, by use of delayed hypersensitivity reactions to recall and cancer antigens, in vitro lymphocyte response to mitogens, and mixed lymphocyte blocking factor activity. The group that received methotrexate showed little change in skin reactivity, a reduction of blocking factor activity, and significant rebound overshoot in in vitro lymphocyte performance. The immunized group showed a tendency to production of blocking factor activity, striking conversion and enhancement of skin reactivity, and little change in in vitro lymphocyte performance. The immunochemotherapy group showed dramatic increases in specific skin reactivity to cancer antigens, up to 2 years after treatment, in vitro lymphocyte rebound overshoot, and reduction of blocking factor activity production. Classic life table analysis of the probability of freedom from metastases in patients with stage-I cancer indicate that the disease-free interval in patients who received methotrexate is longer than in historic and concomitant controls but not as long as in those who received immunization. The best group appear to be those who received combination immunochemotherapy. We emphasize that the small numbers in this pilot study do not yet allow firm conclusions to be made.

From 1949 through 1972 at Memorial Sloan-Kettering Cancer Institute, 72 breast cancer patients developed a synchronous or metachronous solitary lung shadow. Forty-three had separate primary lung cancers; 23 had breast carcinoma metastases and six had benign lung lesions. Of these, 47% were asymptomatic and the lesions were discovered by routine chest roentgenograms. Among 49 patients who underwent pulmonary procedures, secondary involvement of regional lymphatics was noted in 22, nine of which were daughter metastases secondary to the breast deposit. In such a setting, a radical lobectomy (or pneumonectomy) would seem the operation of choice. Four patients who had primary lung cancer and five patients with pulmonary breast metastases survived five years after the thoracic procedure. Prolonged survival in these patients bore no relationship to age, sex, state of axillary lymph nodes or length of interlude between the breast and the lung cancer. Early diagnosis, the extent of the cancer and adequate excision seem to influence end results. When other primary cancers were present, in addition to those of breast and lung, these did not seem to diminish the chance for survival provided they were treated as if they existed alone. The need for strict periodic and continual followup examinations, not only in breast, but also for all cancer patients is essential for early detection of metastases or new primaries. Chest roentgenograms are an integral part of such a plan. The ambiguity of a solitary lung shadow (or at the most two or three opacities) with a known primary breast cancer requires clarification without delay as to its histologic nature so that proper treatment can be instituted and an accurate prognosis given.

A study was made of histologic type of lung cancer in relation to smoking habit, year of diagnosis, age and sites of metastasis. It comprised 662 autopsies of men during the period from 1955 to 1972. As classified by the WHO system, 35.2 percent were epidermoid carcinoma, 24.6 percent were small cell carcinoma, 25.2 percent were adenocarcinoma and 14.2 percent were large cell undifferentiated carcinoma. The six non-smokers of the series were all found to be in class 3, adenocarcinoma. No clearcut and consistent relationships were observed. Although there was a steady decrease in the incidence of small cell carcinoma during this time period, this observation did not prove to be statistically significant. Small cell carcinomas increased with amount of smoking but not for all age groups. Adenocarcinomas decreased with advancing age but not in all smoking groups. Metastases were found in 96.3 percent of the cases and the sites most frequently involved were regional lymph nodes, liver, brain, distant lymph nodes, adrenals and bone. Small cell carcinomas showed the greatest percentage of involvement for those major sites and for the same sites, epidermoid carcinoma showed the lowest percentage.

In a consectuive series of 734 patients with malignant tumorous of the lung, sarcoid reactions were observed in the mediastinal lymph nodes in 20 cases, i.e. in 3.2% of the 630 patients in whom these nodes were studied. Among these 20 patients, sarcoidosis was suspected in three. In two of these, granulomata were revealed in the tumour. Another two had metastases in the affected lymph nodes. All the common histological types of lung tumour were represented in the patients, but squamous-cell carcinomata showed a statistically significant preponderance as compared with anaplastic carcinomata. Three causes of such sarcoid reactions have been suggested: 1. an immunological reaction to substances released by the tumour and transported along the lymphatics; 2. an unrecognized sarcoidosis predisposing to lung cancer; 3. the co-existence of sarcoidosis and malignant tumour, possibly due to a common aetiological factor. The significant preponderance of squamous-cell carcinomata observed in this study is in favour of the first theory, because the slower growth and higher tendency to necrosis of this tumour type may be assumed to give rise to a more vigorous and longer-lasting stimulation of the regional lymph nodes.

A total of 219 patients with proved lung cancer were studied to determine whether postresection irradiation improves survival. The results showed that postresection irradiation improved survival among patients with hilar and mediastinal lymph-node metastases of all histological types but did not improve survival among patients without node metastases. The authors recommend that patients with resectable lung cancer involving the hilar and mediastinal lymph nodes be treated by a combination of surgery and radiotherapy.

Metastatic disease involving the stomach is an unusual and difficult clinical problem. A review of 1010 autopsies of patients with cancer disclosed 17 cases of gastric metastases (an incidence of 1.7%), with breast cancer, lung cancer, and melanoma being the most frequent primaries. The clinical manifestations of epigastric pain, melena, and anemia are nonspecific, necessitating radiographic examination of the gastrointestinal tract. The radiographic findings are usually sufficient to suggest the diagnosis.

From 1963 to 1971, 105 patients with histologically proved cancer of the lung were explored at Memorial Hospital and underwent interstitial implantation using encapsulated sources of radon 222 (53 patients) or iodine 125 (52 patients). These lung cancers were considered unresectable because of extension of the disease into the mediastinum with fixation or invasion of the major vessels, trachea, and esophagus or chest wall involvement. No apical lesions, which have a better prognosis, are included in this review. Sixty-nine patients had epidermoid cancer, 24 had adenocarcinoma, and the remaining 12 had various other histological types. All patients were staged according to the criteria proposed by the American Joint Committee using the TNM definitions (standing for tumor, nodes, and metastasis). Local control was obtained in 8 of 10 patients (80% with clinical Stage I and II unresectable cancers of the lung and in 44 of the 95 (46%) with clinical Stage III lung cancer. The two-year survival was 50% for Stages I and II and 7% for Stage III. Five patients have survived for five years or more. The complications, disease-free interval, local recurrences, distant metastases, and survival are presented and indications for this type of therapy outlined.

Thirty patients with an advanced bronchogenic carcinoma were treated with a combination of adriamycin and 5-fluorouracil; in eight the size of the tumour or its metastases was reduced by over 50%, and eight further patients experienced useful relief of symptoms. This drug combination is useful in the magagement of lung cancer.

Thirty-nine patients were given 67Ga intravenously before thoracotomy because of suspected lung cancer. Specimens of relevant tissue were removed and counted in a well-counter. The uptake of 67Ga in bronchogenic epidermoid and anaplastic tumours was greater than the uptake in normal lung tissue, while the uptake in adenocarcinomas seemed to be equal to that in normal tissue. Two out of seven benign lesions showed greater uptake than normal tissue. Thus 67Ga seems to be of limited value in the differentiation of malignant from benign lesions of the lung. The uptake in lymphatic tissue showed a great variation which did not indicate whether metastases were present or not. For this reason 67Ga seems to be of no use for demonstration of metastases in regional lymph nodes from cancer of the lung.
