This study deals with 11 cases of thyroid medullary carcinoma of which 7 were familial cases including 3 cases of Sipple's syndrome and 4 cases of sporadic cases. There were also 2 cases of Cushing's syndrome. In addition to the previously described English literatures about human medullary carcinoma of the thyroid, the rod-shaped body with cristae and an abundant glycogen particles in the cytoplasm, nuclear inclusion bodies of cytoplasmic invagination and microvilli at the surface membrane of gland formation were found in our cases. The mean and mode diameters of secretory granules of all familial cases with only calcitonin secretion were larger than those of the sporadic cases with ectopic ACTH and beta-MSH in addition to calcitonin secretion. Ultrastructural study on non-cancerous follicles of grossly normal thyroid of two cases of early familial medullary carcinoma disclosed apparently increased C-cells which were not intrathyroidal metastases. It is supposed that the increased C-cells in the thyroid of the familial cases are multicentric C-cell hyperplasia.

Hepatitis B surface antigen and antibody were sought in sera collected from patients with hepatic cell carcinoma and from healthy blood donors. The frequency of the antigen among the patients was significantly higher than that among blood donors who served as controls (p = less than .01) but no significant difference was found in estimated exposure to hepatitis B virus between hepatic cell carcinoma patients and African blood donors. However, exposure to hepatitis B virus was significantly less frequent (p = less than .01) among European blood donors when compared to African blood donors.

One thousand referred patients with breast symptoms, a history of breast disease, or a family history of breast carcinoma have been examined at a suburban breast clinic. This is a preliminary survey of the data and results so far obtained from the initial examination of these patients. The examination consisted of history-taking by means of a questionnaire, physical examination of the breasts, thermography and xeromammography. A report correlating the findings was forwarded to the referring doctor in each case and any necessary action was indicated in the report. Seventy-eight patients were thought to require biopsy of a suspicious lump or mammographic lesion (7.8% of the total number); 76 patients actually had biopsies, and 18 patients were found to have carcinoma of the breast (23.8% of the total number of patients who had biopsies). The overall incidence of carcinoma in the 1000 women attending the clinic was 1.8% at the initial visit. While general population screening for breast carcinoma may be hard to justify, from both the detection rate and an economic point of view, it would appear from our experience to date that screening of selected high-risk referred patients is justified and, in fact, desirable.

Carcinoma tissues induced by 3'-methyl-4-dimethylaminoazobenzene were investigated both morphologically and biochemically. The most prominent histological pattern was an undifferentiated carcinomatous one. While this type of carcinoma, histologically, appeared to be due to a uniform population of cells, electron microscopic examination revealed that the carcinoma tissue was composed of many types of cells including cells that contained either the brush border or the mucous droplets seen in goblet cells. In addition, tumor cells that contain serotonin-like granules were noticed. An electrophoretogram of alkaline phosphatase in the tissue extract of this type of carcinoma revealed distinctly the presence of its intestinal isozyme. These findings evidently show that carcinoma induced by 3'-methyl-4-dimethylaminoazobenzene includes in addition to the cells differentiated toward hepatocytes or cholangiolar cells, those differentiated toward intestinal epithelial cells.

A review was made of the presentation, treatment, and follow-up of 20 patients with adenoid cystic carcinoma and 12 patients with mucoepidermoid carcinoma of the bronchus who were seen at the Mayo Clinic during the 50 year period 1927 through 1977. Three forms of therapy were employed: complete surgical resection, radiation therapy alone, and radiation therapy after endoscopic removal of tumor tissue. Superior results were obtained in the group with adenoid cystic carcinoma, when complete resection was possible. Significant survival and palliation of sepsis was achieved with subtotal resection. The mucoepidermoid carcinomas in this series were classified on the basis of histologic differentiation. Mucoepidermoid carcinoma of Grade 1 was managed by conservative pulmonary resection. Mucoepidermoid carcinoma of Grades 2 and 3 showed a greater propensity for malignancy. Widespread dissemination caused death with unresectable high-grade mucoepidermoid carcinomas of Grades 2 and 3.

Twenty-five cases of solitary nodular adenocarcinoma of the human lung were studied histochemically and ultrastructurally and their morphological characteristics were compared to the cells observed in the control lungs. Adenocarcinoma cells of the human lung may be classified into following four types: Type A--cells resembling the bronchial goblet cell; Type B--cells resembling the mucous cell of the bronchial gland; Type C--cells resembling the type II alveolar lining cell; and Type D--cells resembling the nonciliated bronchiolar cell. Twenty-one cases belonging to Type D (84%) and two cases to Type B (8%), and one case each to Types A (4%) and C (4%). For the histogenesis of adenocarcinoma of the human lung, nonciliated bronchiolar epithelium may be the most important. A comparison of 10 cases of bronchiolo-alveolar carcinoma with 15 cases of ordinary (acinar and papillary) adenocarcinoma revealed no clear differences either histochemically or ultrastructurally.

This report presents a rare histological variation of medullary (C-cell) carcinoma of the thyroid, referred to as giant cell type, which is similar to that found in anaplastic carcinoma of the thyroid, or choriocarcinoma. The giant cells in this case possessed specific immunofluorescence for calcitonin and secretory granules in the cytoplasm. The giant cells were tumor cells of medullary carcinoma and could be distinguished from anaplastic carcinoma of the thyroid by various histological characteristics, such as nuclear invagination, an intermingled pattern of giant cells with typical small solid cells, infrequency of mitosis, and the existence of amyloid stroma.

BK virus (BKV), a human papovavirus, was inoculated iv into 3-week-old Syrian golden hamsters. Between 2 1/2 and 9 months after inoculation, 82% of the animals developed tumors. The induced neoplasms were ependymoma, carcinoma of the pancreatic islets, osteosarcoma, adenocarcinoma, angiosarcoma, angioma, lymphoma, and seminoma. Hypersecretion of insulin, glucagon, C-peptide, and calcitonin was detected in tumors of pancreatic islets. BKV etiology of tumors was supported by the following evidence: 1) No tumors with BKV-specific markers appeared in animals given injections of buffer, animals inoculated with BKV neutralized by anti-BKV-specific serum, or uninoculated controls; 2) BKV tumor (T) antigen was detected by immunofluorescence and complement fixation tests in tumors of animals inoculated with infectious BKV and in transplanted tumors; 3) antibodies to BKV T-antigen were detected in sera of animals bearing primary or transplanted tumors; 4) BKV could be activated by Sendai virus-mediated fusion of neoplastic cells with susceptible Vero cells; and 5) no endogenous hamster oncornaviruses were found in tumors.

Since small cell carcinoma is a treatable disease, with surgery being beneficial in a few cases and with chemotherapy, radiotherapy, and immunotherapy contributing to prolonged survival in patients with inoperable disease, it is essential that the clinical and pathologic features of small cell carcinoma be quickly recognized in a newly presenting patient so that appropriate therapy may be offered.

No prognostic factors could be identified that influence survival in patients with small cell carcinoma undergoing traditional therapy. These findings identified small cell carcinoma (1) as a distinct disease entity with reference to non-small cell carcinoma, (2) as a nonsurgical disease, and (3) as a disease demanding systemic treatment.
