The choice of operation for ductal carcinoma of the pancreas is as yet not clear. Failure to make an early diagnosis still stands out as the major problem in the treatment of this disease and as a result the resectability rate is exceedingly low. Between 1964 and 1973, nineteen total pancreatectomies were performed at Peter Bent Brigham Hospital for all tumors of the pancreas. Sixteen of these were for ductal carcinoma. The mortality was 12.5 per cent. When total pancreatectomy is compared with the Whipple procedure and a simple bypass procedure and when the tumor disease encountered is corrected for stage of disease, it is apparent that total pancreatectomy carries a statistically significant longer survival for patients with Stages I and II disease (no lymph node involvement) than the other two procedures. For Stages III and IV, there is no difference in survival between the three different operations. We therefore conclude that total pancreatectomy carries a better survival prognosis than other procedures performed for Stage I and II ductal carcinoma of the pancreas.

A human breast tumor cell line BT-474 derived from an invasive ductal carcinoma was experimentally infected in vitro with a mouse mammary tumor virus from the TIII strain (RIII-MuMTV). The virus that replicated in the human cells was characterized as a mouse virus by immunofluorescence, electron microscopy and the presence of a specific RNA-directed DNA polymerase. The cells themselves were human as per the karyotype and isoenzyme migration patterns. It is concluded that human cells are susceptible to the mouse mammary tumor virus and can, eventually, support its replication.

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.

Infiltrating ductal carcinoma is an extremely rare neoplasm in the teenage or pre-teenage child. Routine pediatric physical examination should include careful examination of the breast and all palpable masses should be excised. Carcinoma occurring in the prepubertal child carries an improved prognosis particularly if the tumor stains PAS-positive. Carcinoma occurring in the postpubertal teenager probably carries the same prognosis as that in the adult and should be treated in a similar manner. The authors discuss such a case occurring in a 13-year-old girl.

Erytrophagocytosis by epithelial tumor cells has been observed in metastases of ductal carcinoma of the female breast. Some malignant cells of this tumor seem to be capable of phagocytizing and digesting extravasated red blood cells with for formation of residual hemosiderin probably from their hemoglobin content. Erythrophagocytosis has been observed only in hemorrhagic areas of the tumor. Erythrophagocytosis has been observed only in hemorrhagic areas of the tumor. Although the nature of this phenomenon is unknown, it is postulated that acquired hematological disturbancess during the natural course of the malignant disease affect the surface of the red blood cells making them vulnerable to phagocytosis by the malignant cells. This case seems to represent the second time such a phenomenon has been reported in an epithelial neoplasm in man. However, it has been more frequently observed in reticulo-endothelial malignancies. The possible occurence of this phenomenon should alert pathologists to search for it in primary and metastatic epithelial tumors and in living patients to correlate pertinent hematological studies in an attempt to elucidate its possible significance.

It is apparent that we are dealing with a very lethal disease. It is also apparent that this disease is increasing in frequency. In terms of treatment, it is clear that the survival figures between carcinoma of the pancreas and carcinoma of the common duct, papilla of Vater, or duodenum present great differences. The pancreatic tumors do very poorly by comparison. A comparison of the survival figures following a Whipple resection and following a bypass procedure reveal similar results, except when dealing with a very small pancreatic head lesion or when dealing with a malignancy of the papilla of Vater, lower end of common duct, or duodenum. The latter tumor types do better with a Whipple resection than a bypass. A comparison between total pancreatectomy and a Whipple resection for ductal carcinoma of the pancreatic head reveals better results in terms of length of survival following total pancreatectomy as long as one considers only Stage I or Stage II disease and excludes Stage III disease. A Whipple procedure is advocated for carcinoma of the papilla of Vater, common duct, or duodenum, because survival figures are quite good and many patients escape the need for insulin and pancreatic extract replacement. It is too early to evaluate the survival figures that follow regional pancreatectomy.

Carcinoma of the breast is relatively uncommon in men. Represents somewhere between 0.9 to 1.5 of all tumors of the breast. Most patients are within the 7th to 8th decade of life. The most common symptoms at the time of presentation are a tumor mass in either breast, ulceration of the nipple or nipple retraction or fixation of the skin. Extension to the axiliar nodes takes place early in the course of the disease. The presence of nipple discharge should be considered expression of carcinoma of the breast unless otherwise proven. The final diagnosis is established by biopsy. The most common form of carcinoma of the breast is the ductal carcinoma. The surgical management takes basically that followed in carcinoma of the breast in the female patient. Also orquiectomy has been used which is equivalent to ovariectomy in woman. In the presence of metastasis both estrogens and androgens have been used. Hypophysectomy and post-op radiation therapy has been used. Most recently chemotherapy has been widely used in those cases with widespread metastasis. However, in spite of all these efforts carcinoma of the breast in the male still carries a very serious prognosis. We present our experience in 16 cases.

Eight cases of a rare, distinctive variant of infiltrating mammary carcinoma featuring benign multinucleated osteoclast-like giant cells are reported. The multinucleated osteoclast-like giant cells are reported. The multinucleated giant cells were associated with ductal carcinoma in five cases and with infiltrating lobular carcinoma in three cases. Although three patients had lymph nodal metastases in level one, none of the nodal metastases contained giant cells. From the limited follow-up data of this report, it seems likely that the prognosis for patients who have this type of adenocarcinoma is not especially favorable. The observation that the giant cells generally occurred in areas of prominent angiogenesis suggests that the angiogenesis may be induced by some chemical substance produced by the tumor cells. Biochemical and immunologic investigations may eventually provide an explanation for this unusual morphologic manifestation of host reaction to mammary carcinoma.

Whipple resections for pancreatic head carcinoma are often inadequate because tumor is left behind in the body and tail. Thirty-six patients have undergone total pancreatectomy for various conditions, of which 25 have undergone total pancreatectomy, for ductal carcinoma. Thirty-seven per cent of these 25 patients have shown histologic evidence that a Whipple resection would not have adequately removed tumor-bearing pancreatic tissue. Three patients had carcinoma spreading up and along the common bile duct from a primary ductal carcinoma in the head of the pancreas. Four patients had tumor infiltrating in continuity into the pancreatic body and tail at a distance from the palpable tumore in the head well to the left of a Whipple transection site. Five patients had widespread multifocal autonomous tumor involving other areas in the gland but with tumor palpable only in the head of the pancreas. Three patients (12%) died postoperatively. The two year survival rate is 32%, and the five year survival, 19%. Histological factors affecting the survival prognosis include 1) positive nodes, 2) tumor extension up the common duct, and 3) intrapancreatic extension and multicentricity of tumor mandating total pancreatectomy for hope of cure in at least 38% of cases.
