Significance of lymph node metastasis in differentiated thyroid cancer.

In age-matched patients with differentiated carcinoma of the thyroid, the tumor recurred in 32 per cent of those with lymph node metastases and in 14 per cent of those without lymph node metastases. Twenty-four per cent of patients with nodal involvement at the initial examination died of thyroid cancer, whereas only 8 per cent of those without nodal involvement died of thyroid cancer. In patients less than forty years old, there were no deaths in those without nodal metastases bu there were three deaths (11 per cent) in patients with nodal metastases. In patients more than forty years old, nine (41 per cent) iwth nodal metastases died of tumor, and four (15 per cent) without nodal metastases died of tumor. In the presence of positive nodes the death rate was substantially greater in the older than in the younger patients. Nodal involvement has an adverse effect on prognosis, but appears to be less important than the age of the patient.

Management of external gastrointestinal fistulas.

We analyzed the course of 186 patients with external gastrointestinal fistulas treated at the University of California Medical Center, San Francisco from 1968 to 1977. There were 82 patients in the earlier group (1968-1971) and 104 patients in the later group (1972-1977). The groups differed in that 35% of patients in the earlier group received TPN, but 71% of patients in the later group received TPN. Of the patients who did not receive TPN, 93% had been adequately nourished using tube feeding methods. The two groups were otherwise similar. The fistula-related mortality (11%) and the spontaneous closure rate of the fistulas (32%) was unchanged over the ten year period. Thus, the principal impact of TPN was to simplify the nutritional management rather than to alter the outcome. When malignancy, previous abdominal irradiation, Crohn's disease, or a short (<2 cm) fistula tract were present, spontaneous closure was less likely than when none of these factors were present (20% versus 47%). Sixty-eight per cent of the deaths occurred in patients with uncontrolled sepsis. Fifty per cent of the deaths were due to the primary disease and were unrelated to the fistula. Spontaneous closure could not be expected to start until sepsis was controlled. Because over 90% of patients whose fistulas closed spontaneously did so within one month after infection was eradicated, we recommend operative closure for most fistulas that persist beyond that time. The most reliable operation is excision of the bowel from which the fistula arises with end-to-end anastomosis. Fistulas not amenable to excision should be managed by bypass.

Pancreatic tumor of mesenchymal origin presenting as obstructive jaundice.

A case of an unusual tumor occurring in the head of the pancreas is presented. Definitive diagnosis could not be made, the lesion being either a low grade myxofibrosarcoma or a benign fibrous histiocytoma. The literature is discussed and several cases believed to be pancreatic sarcomata are presented, only one of which was definitely of pancreatic origin. No other case of fibrous histiocytoma of the pancreas has been reported.
