A retrospective survey of 100 patients dying from carcinoma of the lung showed that neurological presentation and central nervous system metastases are more frequently present when the primary carcinoma is situated in the peripheral lung tissue (including lung apex). The high incidence of cases presenting neurologically and the high incidence of single secondary deposits involving the central nervous system from peripheral or apical growths suggest a difference in the mode of spread or other properties of such growths compared with the more common central carcinoma.

Bilateral bone-marrow examinations from the posterior iliac crests were routinely performed as a pretreatment staging procedure in 89 consecutive patients with small-cell anaplastic carcinoma of the lung. Bone-marrow involvement was found in 20 patients (22.5%), in 9 (10.1%) only on one side, and in 11 (12.4%) on both sides. Aspiration was found to be significantly superior to biopsy, being positive in 25 examinations as compared with 14 positive biopsies. Compared with unilateral bone-marrow examination the positive findings increased by approximately 30%. Bilateral bone-marrow examinations are recommended in patients in whom the detection of bone-marrow metastases will have therapeutic implications.

This report gives the complete findings at one year of a study comparing radiotherapy (Rt) with radiotherapy followed by 3-drug chemotherapy (RtC3) in the treatment of histologically proven small-cell carcinoma of the lung of limited extent. Over the 12-month period there was a significantly increased survival for the RtC3 patients (P = 0.002) and at 12 months 18% of the 121 Rt but 34% of the 115 RtC3 patients were alive (P = 0.009). The median survival for the Rt series was 25 weeks and for the RtC3 series 43 weeks. There was evidence of recurrence of the primary cancer in 32 (32%) of the 99 Rt and 20 (26%) of the 76 RtC3 patients who died. Distant metastases appeared earlier and were more frequent in the Rt series (P less than 0.0001) and over the 12-month period 79% of the Rt and 57% of the RtC3 patients developed distant metastases (P less than 0.0005). At 12 months only 8% of the Rt but 26% of the RtC3 patients were alive and free of metastases. Adverse reactions occurred much more frequently in the RtC3 series; 32% of the Rt series as against 83% of the RtC3 series had reactions, the most common being nausea and vomiting (13% Rt, 71% RtC3) and the most serious being marrow depression (23% Rt, 54% RtC3). No important differences were found among the survivors in the 2 series at 3, 6 or 12 months, in general condition, physical activity or respiratory function. It is concluded that radiotherapy plus chemotherapy was superior to radiotherapy alone, although chemotherapy did not protect patients from recurrence of primary growth.

A rare case of small-bowel perforation due to metastasizing primary bronchogenic carcinoma is reported. A 64-year-old man presented with acute abdominal crisis from perforation of a metastatic focus in the wall of the small intestine. A 13-cm segment of small bowel, containing a firm mass which surrounded a 1.0 X 2.0-cm perforation, was resected. Because of widespread metastases, the patient received only palliative treatment. He died 27 days after admission. Perforation of a metastatic focus in the small bowel is considered a late complication of carcinoma and indicates a very poor prognosis. This is only the eighth reported case of such a complication of metastasizing lung carcinoma.

Patterns of failure after treatment for carcinoma of the lung were analyzed by the major WHO cell types. Only diagnoses of the review panel of the Veterans Administration Lung Group were used. First sites of progression were analyzed for 185 patients in a clinical trial, and cause of death was evaluated in 300 consecutive autopsies from VALG studies. Clinical progression was similar for all cell types--20% failed locally and 30% developed metastases. Carcinomatosis or brain metastasis caused death in only 27% of patients with squamous, in over half with large cell and adenocarcinoma, and in 70% of patients with small cell carcinoma. Complications of the local tumor (infection, hemorrhage, and respiratory failure) caused death in 50% of patients with squamous, in 1/3 with large cell and adenocacrinoma, and in 21% of those with small cell carcinoma. These clinical and autopsy data suggest the need for aggressive treatment of the local tumor in all cell types, and systemic therapy for small cell carcinoma. Both local and systemic approaches are needed for large cell and adenocarcinoma.

The records of 177 patients with small cell carcinoma of the lung were reviewed to determine parameters associated with brain metastases. Complete autopsy, including examination of the brain, was done in each case. Of the 70 cases of brain metastases, only two patients (3%) were aged 70 years or more as compared with 19 (18%) aged 70 years or more who did not have brain metastases. Patients with brain metastases had a longer median survival as compared with those without brain metastases. Patients with brain metastases had involvement of the thyroid and kidney more frequently (23% and 34%, respectively) compared with patients without brain metastases (8% and 13%). Thus, patients who have brain metastases tend to (1) be less than 70 years of age; (2) have a longer survival; and (3) have a higher incidence of metastases to the thyroid and kidney.

The relations of calcitonin concentrations to the presence of bone marrow metastases and to the concentrations of calcium, parathormone and gastrin in serum were investigated in 74 untreated patients with small cell carcinoma of the lung. Calcitonin concentrations were enhanced in two thirds of the patients, while serum calcium concentrations were normal in all. In 19 of 57 patients parathormone concentrations were slightly above the normal range, but the concentrations of parathormone and calcitonin were not correlated. Bone marrow metastases had no influence on the concentration of serum calcitonin. Finally, a small inverse correlation between the concentrations of gastrin and calcitonin in serum was observed. The results resemble those of the calcitonin-producing medullary carcinoma of the thyroid, supporting the suggestion of an ectopic source of hypercalcitoninemia in small cell carcinoma of the lung.

Upper abdominal CT scans were performed on 45 consecutive patients with biopsy proven but previously untreated small cell carcinoma of the lung. Evidence of metastases was found in 16 (36%) patients. The most common site of metastases was the liver (27%). CT had a sensitivity of 88% and specificity of 94% as compared with biopsy results. Evidence of retroperitoneal metastases was found in seven (16%) patients.

A case of bronchiolo-alveolar carcinoma of the lung was studied by light and electron microscopy. Type II granular pneumocytes were seen in the lymph node metastases of the tumor, a finding not reported previously. We feel that the presence of these cells in metastatic foci indicates their neoplastic nature, and provides evidence that bronchiolo-alveolar carcinoma arises from type II cells.

Methotrexate (MTX) covalently bound to bovine serum albumin (MTX-BSA), injected ip (10 mg/kg) once every 4 days for a total of 4 doses, was more effective than an equivalent dose of free MTX in reducing the number of metastases observed in female (C57BL/6 X DBA/2)F1 mice bearing the sc implanted Lewis lung carcinoma. Treatment with the high-molecular-weight derivative of MTX in addition caused a decreased rate of growth of the primary tumor and a modest increase in the life-span of the tumor-bearing animal. When tumor-bearing mice were killed after receiving injections of [3H]MTX or [3H]MTX-BSA, no difference in the amount of drug was found at the tumor site after 1 hour; however, after 8 or 24 hours, twice as much radioactivity was found in the tumors of mice treated with carrier-bound drug. Analysis of this radioactivity indicated a ratio of 60--80% carrier-bound to 20--40% free MTX.
