Clinical and pathological characteristics of carcinosarcoma of the esophagus: report of four cases.

Carcinosarcoma of the esophagus is a rare malignant neoplasm composed of both carcinomatous and sarcomatous elements. Four out of 850 patients with carcinoma of the esophagus or the cardiac portion of the stomach undergoing operation at Capital Hospital, Beijing, had carcinosarcoma of the esophagus. They ranged from 50 to 58 years old, but only 45% of all 850 patients with carcinoma were in the age group from 51 through 60 years old. All 4 patients with carcinosarcoma of the esophagus were men. On barium swallow esophagogram, the 4 patients had a characteristic intraluminal polypoid lesion in the middle third of the esophagus. Such lesions of the esophagus also can occur in patients with benign fibrovascular polyps, leiomyoma, and the polypoid form of esophageal carcinoma and esophageal melanoma. The last two can be differentiated from carcinosarcoma only by pathological examination after excision. After radical excision and esophagogastrostomy, the 4 patients were followed up for 19, 4, 4, and 3 years. They were in good condition without recurrence.

Bronchogenic carcinoma: a study of patients treated at Capital Hospital, Peking, China.

From 1961 to 1972, 123 patients with lung cancer underwent operations at Capital Hospital, Peking, China. Ninety-six patients had resectable lesions and 27 did not, a resectability rate of 78%. Four patients (4.2%) died immediately postoperatively. Complications occurred in 8 (8.3%) patients. Five-year survival in this group of 92 survivors was 26 (28.3%). Ten-year survival among 49 patients was 10 (20.4%). Among the 92 five-year survivors, 41.2% had squamous cell carcinoma, 25% had adenocarcinoma, and 16% had undifferentiated carcinoma. Patients with squamous cell carcinoma had a much longer survival than the others. Six factors appear to influence survival after resection: cell type, presence of lymph node metastases, presence of tumor emboli in blood vessels, sex, age, and location. Men about 50 years of age, with a peripherally located squamous cell tumor and with no tumor emboli or lymph node metastases, have a good chance of surviving a pulmonary resection for ten years.
