Recurrence in early gastric cancer: a pathologic evaluation.

The cause of death in 26 of 220 cases of early gastric carcinoma was studied, particularly in relation to the mode of recurrence. Of the 26, 7 patients died of disease related causes and gross appearance revealed that 4 cases were IIa predominant, 2 were IIc (or +I), and 1 was IIc predominant. Histologic examination indicated that all 7 cases were differentiated-type adenocarcinomas. Two of 7 recurring carcinomas were due to residual carcinoma in the resected stumps and 5 patients had hematogenous metastases, particularly in the liver. Eighteen of the 26 patients died of other causes, in 1 case of unknown causes, and it is interesting that in 5 of the 18 cases, simultaneous or nonsimultaneous double carcinomas at sites other than the stomach were noted. In order to prevent recurrence in early gastric carcinoma, it is important that no carcinoma be left in the resected stump or remnant, and that the prophylaxis be achieved through the administration of adequate amounts of anticancer chemotherapy, in order to prevent hematogenous metastasis, particularly to the liver.

Anaplastic carcinoma of the esophagus. Report of three cases and their histogenetic consideration.

The autopsies of three cases of esophageal anaplastic carcinoma with an oat cell pattern are presented. Grossly, each case revealed a fungating growth and showed extensive metastases all over the body. The histology bears a striking resemblance to that of oat cell carcinoma of the lung, occasionally showing rosette formation, mucin secretion, and intracytoplasmic argyrophil granules in each case. These peculiar carcinomas most probably were derived from the esophageal submucosal glands. They were composed of both a cell group of argyrophil variety and a group of mucus-secreting variety which may have originated from the more primitive cells capable of differentiation into either variety.

Pseudosarcoma and carcinosarcoma of the esophagus.

Two cases of polypoid carcinoma with pseudosarcoma and one of so-called carcinosarcoma of the esophagus are presented. The clinical and morphologic characteristics of these tumors are described and the literature is reviewed. It is postulated that pseudosarcomas and so-called carcinosarcomas belong essentially to the same pathologic entity because of their similar morphologic and biologic aspects. The histogenesis of the sarcoma-like elements of these tumors support the theory of epithelial origin on the basis of the sarcoma-like transformation of squamous cell carcinoma and of the presence of epithelial elements in the "sarcomatous" areas.

Carcinomas of the stomach in the young adults.

The clinical and pathologic characteristics of the gastric carcinomas in the young adults were described in special comparison with the carcinomas in the old men. They were found to be similar in many respects, but had some different features like the histologic findings with particular references to the histogenetic background.
