Retrospective review of 160 patients with carcinoma of the supraglottic larynx was accomplished for the period 1964 to 1974. The majority were treated by low dose preoperative radiation and conservation surgery and the rest by preoperative radiation and total laryngectomy or radiation alone. Relapse-free and actuarial 5 year survival for all patients was 71% and 45%, respectively. Of primary and neck failures, 85% occurred within 2 years. Primary, nodal, and distant failures occurred in 11%, 21%, and 14% of all patients, respectively. Of 40 T and/or N failures, 33 (83%) occurred in the neck and three T and six N failures (23%) were surgically salvaged. Voice was preserved in 71% of the patients. Major complications were noted in 16% and minor complications in 26% of surgically managed patients; operative mortality was 4%. The presence of microscopic lymph node metastases best predicted those who would later develop T and/or N failure and distant metastases. Second primary tumors occurred in 26% and the leading cause of death was tumor.

From January 1963 to December 1968, 148 patients underwent thoracotomy for bronchogenic carcinoma. In 123 patients either lobectomy or pneumonectomy was performed (resectability rate of 84 per cent). The over-all operative mortality was 3.4 per cent. Forty of the patients undergoing resection (34 per cent) are alive and free of cancer five years after surgery. Tumor size, nodal involvement, cell type, location, symptoms, and extent of surgery were studied in relation to the long-term results. Five year survival was directly related to the size of the tumor and the extent of nodal involvement. No patients with mediastinal nodal involvement or with lesions larger than 7 cm in diameter were among the long-term survivors.

In a review of the histologic sections of axillary and internal mammary lymph nodes removed during surgery for invasive ductal carcinoma of the breast, we found that 16 of 17 patients in whom sinus histiocytosis was the dominant lymphoid proliferative reaction are alive with no evidence of cancer 5 or more years after operation. In contrast, 5 of 6 patients in whom germinal center hyperplasia was the only significant reaction found died of cancer in less than 5 years. Patients with both sinus histiocytosis and germinal center hyperplasia in significant amounts had survival that was intermediate; 17 of 25 of these patients are currently alive and apparently free of cancer. In addition, 5 of 6 patients in whom no evidence was found of any lymphoid proliferative reaction and 3 of 3 patients with diffuse cortical hyperplasia in their axillary lymph nodes died of cancer in less than 5 years. Germinal center hyperplasia was associated with nodal metastases anatomically in individual lymph nodes and statistically in the series of cases. The internal mammary lymph nodes of most cases showed less proliferative reaction to tumor than the axillary lymph nodes. The pattern of proliferative reactions in lymph nodes and its correlation with survival after surgery suggest that different immune reactions may either suppress or enhance the growth of carcinoma of the breast.

Clinical and pathologic staging of breast cancer are discussed. A new pathologic staging system is presented: numerical scores are assigned, in cases of infiltrating ductal carcinoma of no specific subtype, for tumor size, histologic grade, amount of stromal infilttration, vascular invasion, axillary lymph nodal metastases, and sinus histiocytosis in axillary lymph nodes. Staging by this system correlates well with survival in cases treated by radical mastectomy. The essential features to be studied in pathologic specimens of breast cancer are also indicated.

The morphologic appearances of regional lymph nodes in radical mastectomy specimens obtained from 303 women entered into a prospective study of invasive breast cancer were categorized into patterns that have been considered to reflect immunologic function. An attempt was made to correlate these with 31 other histological and 8 clinical features, including short-term treatment failure (3 months to 4 years, average 24 months). No significant relationship to the latter was encountered. However, a lymphocyte predominance pattern was significantly associated with a stellate tumor border, absent cell reaction within the dominant tumor, absent sinus histocytosis of lymph nodes, combination tumor types, and a patient age of 55 years or more. A similar relationship between age of patient and sinus histiocytosis was found with the germinal center predominance pattern. In addition, this histologic appearance was associated with circumscribed tumors, severe cell reaction, and the infiltrating ductal carcinoma NOS and medullary types. Nodes with an unstimulated appearance were also found to be related to an absent cell reaction but marked sinus histiocytosis and a patient age of 45-54 years. Possible reasons for the differences between these findings and those of others relating prognostic value to such assessment of nodal histology is discussed, as are the findings of studies relevant to the identity of immunologic function with the morphologic appearance of nodal structure. The findings from this study fail to indicate any value of such nodal assessments as prognostic discriminants for breast cancer. Although longer periods of observation might alter this conclusion, such an event is regarded as unlikely.

Five cases of the type of mammary carcinoma that has been designated "signet-ring cell carcinoma" are presented. This tumor is characterized by the presence of numerous cells containing intracellular mucin, without large amounts of extracellular mucin as is seen in colloid (gelatinous, mucinous) carcinoma of the breast. Although such cells may be seen in many mammary carcinomas, they are never as frequent as in the variant described. Ultrastructurally, the most characteristic finding is the presence of numerous intracellular lumina containing material which appears to represent the mucin identified with the light microscope. This finding differs from that in colloid carcinoma, in which the scantier intracellular mucin occurs in the form of intracytoplasmic membrane-bound vesicles. The five tumors in the present series were all associated with either in situ lobular carcinoma or a "sinus catarrh"-like pattern of nodal metastases, or both. On the basis of these light and electron microscopic data, the signet-ring cell carcinoma is suggested as a variant of infiltrating lobular carcinoma, clinically and pathologically distinct from colloid carcinoma.

Five stage I and stage II breast cancer patients with sinus histiocytosis in two or more enlarged regional lymph nodes were studied. Peripheral lymphocytes, serum, and nodal lymphocytes were tested in vitro for cytotoxicity against autologous normal and tumor cells. Nodal macrophages were incubated with autologous peripheral lymphocytes and these "activated" lymphocytes then were tested in vitro for cytotoxicity against autologous normal and tumor cells. Peripheral lymphocytes (L) were not cytotoxic to autologous tumor (T) cells at 25:1 L/T ratios. Nodal lymphocytes were specifically cytotoxic to autologous tumor cells. Macrophages from hyperplastic regional lymph nodes transferred tumor specific inmunity to peripheral lymphocytes. Macrophages from small, nonhyperplastic regional lymph nodes did not transfer tumor specific immunity. With the advent of adjuvant chemotherapy and its attack on systemic immunity, a quantitative, immunopathological classification of breast cancer patients is needed in order to properly select patients for further therapy.

Abdominal pansonography was performed in 34 patients after solid renal tumors were diagnosed. Included were evaluation of the inferior vena cava (IVC), the liver, and the retroperitoneal area. Additional findings including hepatic metastases, IVC extension of tumor, and retroperitoneal nodal masses were discovered in 14 patients. The role of pansonography as a noninvasive adjunctive diagnostic tool for more complete staging and treatment planning of renal cancer is discussed.

Records of 374 patients referred to the National Cancer Institute with a diagnosis of sarcoma over a 24-year period were reviewed to study the incidence of lymph node involvement in this disease. One hundred and thirteen patients had operations involving the draining nodal area and evaluation of these nodes for tumor. Only three patients (2.6%) had evidence of sarcoma metastatic to draining lymph nodes. Prophylactic removal or radiotherapy of draining lymph node areas in most adults with sarcomas does not appear to be worthwhile. A comprehensive analysis of the literature is presented.

Papillary carcinoma of the thyroid pursues a long course of local nodal metastases and rarely leads to death. This case reports an occult thyroid tumor which presented as a serous effusion with pure papillary carcinoma. At autopsy, both papillary and undifferentiated carcinoma were found in the thyroid. Although the pleural component was papillary, the fulminant course was that of an undifferentiated carcinoma.
