We studied 202 cases of bronchogenic carcinoma treated surgically between January 1, 1966 and December 31, 1970. Over all, adenocarcinoma was the most common cell type (36.1 per cent). Of 151 patients whose carcinomas were successfully resected, and who lived for at least 30 days postoperatively, 88 had lymph nodes free of cancer. Not surprisingly, 5-year survival was related to lymph node metatases and cell type. The best over-all 5-year survival rate was for large cell carcinoma; it was 52.0 per cent without nodal involvement. Similar figures for epidermoid carcinoma were 29.0 per cent over all, and 26.3 per cent without lymph node involvement; for adenocarcinoma, 19.3 per cent over all, and 32.0 per cent without nodal involvement. For the entire group of 151 patients, the 5-year survival rate was 27.8 per cent over all, and 36.4 per cent without nodal metastases. Among resected patients with mediastinal lymph nodes positive for cancer, the 5-year survival rates were 1 of 10 patients with large cell carcinoma, 1 of 19 patients with adenocarcinoma, and 3 of 12 patients with epidermoid carcinoma. This suggests that in patients with epidermoid carcinoma, the presence of mediastinal lymph node metastases is not, in itself, an absolute contraindication to resectional therapy.

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.

Increased demands are made upon the pathologist to work closely with the surgeon and the mammographer in the interest of early detection. The smallest of cancers and the very earliest phases of neoplastic development are being detected, necessitating fine discriminations between cancer and noncancer. Agreement is not always uniform at these new frontiers of diagnosis, and accuracy is paramount. Tumors are populations of heterogeneous cells. Their morphology lends itself poorly to simple categorization, and their biology is not always accurately reflected in their gross and histologic appearances. Clearly evident to the pathologist are the limitations of morphology, of the light microscope and of routine techniques for examining surgical specimens. Paradoxically, "noninvasive" cancers occasionally metastasize, and lymph nodes originally "free" of cancer are found to contain metastases on more meticulous re-examination. Notwithstanding these limitations a prognostic statement can be made with relative confidence with regard to certain morphologic types of carcinoma. Pure intraductal carcinoma and lobular carcinoma in situ entail negligible threat to normal life expectancy if the breast is thoroughly removed. Other types with a favorable prognosis are intracystic papillary carcinomas and pure mucinous carcinomas. Tumors classified as well differentiated or tubular adenocarcinoma infrequently metastasize and have excellent prospects for cure. Unfortunately, these and other favorable histologic types comprise less than one quarter of all mammary carcinomas. Most carcinomas are without such distinctive features. In this category the degree of anaplasia and the nature of the tumor borders, as well as the presence or absence of blood vessel invasion, dermal lymphatic invasion and metastases in regional lymph nodes, are of major importance in arriving at an estimate of prognosis.

One hundred patients with inoperable (80) or unresectable (20) bronchogenic carcinoma without evidence of spread beyond the thorax and supraclavicular nodes were planned for radical radiotherapy. Seventy-six patients received continuous irradiation (6000 rads in 30 treatments in 6 weeks, TDF 99) and 24 received split course therapy (2 courses of 2500 rads in 10 treatments with a 3 week break between courses, TDF 88). Forty-three patients had squamous cell carcinoma or adenocarcinoma and were considered to have favorable prognostic factors, while 57 patients had unfavorable prognostic factors: undifferentiated large cell or small cell carcinoma, supraclavicular metastases, SVC obstruction, superior sulcus tumors, or bone erosion in continuity with the tumor. Ninety-two patients completed the planned course of treatment. In patients completing treatment, local control of cancer within the irradiated volume was achieved in 58.5% of continuously irradiated patients and 45.4% of patients receiving split course therapy. Median survival was 1.2 months in patients not completing treatment and 12 months for the patients who completed treatment; 19% of the total group survived 3 years. Median and 3 year survivals of 14 months and 20.4% and of 9 months and 11% were observed for patients treated continuously and by the split course techniques, respectively. Corresponding survival figures for patients with favorable and unfavorable prognostic signs were 21 months and 26%, and 4 months and 11%, respectively. Implications of these data for treatment planning and patient selection for radical radiotherapy in bronchogenic carcinoma are discussed.

Umbilical metastases were encountered as the initial presentation of cecal adenocarcinoma in a 62-year-old woman. Intravenous infusion of 5-fluorouracil, along with intralesional injections of 10% 5-fluorouracil, resulted in regression of the tumor masses on the abdominal wall. Although umbilical metastasis is rare, its significance in diagnosing an otherwise silent colorectal cancer warrants the physician's awareness.

The brain isoenzyme of creatine kinase (CK BB) occurs in trace amounts in normal serum and is moderately increased in only a small number of non-oncological conditions. Although many tissues and tumors contain CK BB, we observed serum elevations only in certain carcinomas. Eleven patients with tissue-proven small cell anaplastic carcinoma (SCAC) of the lung had striking elevations of serum CK BB and no evidence of central nervous system (CNS) metastases. Significant increases were also observed in three cases of prostatic carcinoma with no apparent CNS involvement, and in one case each of adenocarcinoma and SCAC of the lung with proven CNS metastases. Three patients with SCAC of lung without distant metastases, three with SCAC of the esophagus with distant metastases but no known CNS involvement, and 17 patients with oncological conditions other than SCAC of the lung or adenocarcinoma of the prostate have failed to show elevation in serum CK BB activity. Serum CK BB may be useful as a diagnostic marker or indicator of metastases for some carcinomas.

The case of a 38-year-old female with primary argyrophil cell carcinoma of the uterine cervix is reported. Two years after operation the patient developed widespread metastases with typical Cushing's syndrome. Microscopically, the tumor consisted of solid anaplastic cells, adenocarcinoma, and squamous cells. The plasma levels of ACTH and cortisol were elevated. Many cells of both the primary and metastatic tumors showed argyrophilia. Almost all the cells of the metastases contained numerous round secretory granules measuring about 117 micrometers in diameter. Small rod-shaped or larger round secretory granules, measuring 250 and 430 micrometers respectively, were also found in a few of these cells. The tumors in the right lung, pancreas, and kidney contained high levels of ACTH, beta-MSH, serotonin, histamine, and amylase. This is the first report of ectopic production of these five substances from argyrophil cell carcinoma of the uterine cervix.

In the patient with clinically localized bronchogenic carcinoma, the pre-treatment peripheral blood lymphocyte count and the thymus-dependent lymphocyte (T cell) level correlated with the prognosis of the tumor histology was either squamous cell, oat cell, or undifferentiated carcinoma. Patients whose pre-treatment lymphocyte count was less than 1,000/ml or whose T cell level was less than 750/ml either died or developed distant metastases by nine months after treatment of their localized tumor. By contrast, 55% of patients whose pre-treatment T cell level was greater than 750/ml were alive and without evidence of metastases nine months after treatment (P less than 0.02). Analysis of survival of these patients by the life-table method through the first post-treatment year further demonstrates the prognostic value of a low pre-treatment lymphocyte count or T cell level. The pre-treatment lymphocyte count and T cell level in patients with adenocarcinoma did not correlate with prognosis.

Adenocarcinoma has become the most common type of cancer of the lung. Its distinct natural history necessitates separation from the other cell types. Results from recent Veterans Administration Lung Group studies show that local-regional failure occurred in 59% of patients after irradiation for adenocarcinoma limited to the thorax. Data from 300 consecutive autopsies reveal that death was caused by intrathoracic complications of the tumor in 38%, and by metastases in 57% of patients. Adenocarcinoma has an intermediate risk of local and distant failure when compared to squamous and small-cell carcinoma. However, brain metastases are most frequent with adenocarcinoma. Preliminary results suggest that prophylactic brain irradiation decreases the frequency of brain metastases. Patients with adenocarcinoma are more likely than those with other cell types to have metastases only in the brain. Prophylactic brain irradiation may make the greatest contribution to improved survival in pateints with adenocarcinoma of the lung.

From April 1970 to October 1977, 19 patients with lung cancer of the upper lobar bronchus orifice underwent radical lobectomy with major bronchus resection. Sleeve lobectomy was accomplished in 11 cases and wedge lobectomy in the remaining 8. The length of the free bronchial margin in the surgical specimen was less than 1 cm in 3 cases, but limited pulmonary reserve did not allow pneumonectomy. Squamous carcinoma was diagnosed in 14 patients, adenocarcinoma in 2, oat-cell carcinoma in 2, and large cell carcinoma in one. Most cases (70%) were pathological stage I. There was one operative death due to anastomotic leakage (5%), and another patient required pneumonectomy completion. Of 13 patients with non oat-cell carcinoma and adequate bronchial resection, none had local recurrence: 3 patients developed distant metastases, and 10 are alive and disease-free after a follow-up period ranging from 16 to 104 months. The authors conclude that in selected lung cancer patients lobectomy with bronchoplastic procedures is superior to pneumonectomy for tissue sparing advantages.
