Selection of high risk groups among prognostically favorable patients with breast cancer.

In a prospective, nationwide, decentralized breast cancer project conducted by The Danish Breast Cancer Cooperative Group (DBCG) the recurrence rate within the first year after surgery was analysed in relation to tumor anaplasia. One thousand forty-eight patients met the requirements of eligibility, i.e. tumor size less than or equal to 5 cm with negative axillary nodes, and no skin or deep invasion. The recurrence rates in tumors with anaplasia Grades I, II, and III were 4, 9, and 14%, respectively (p = 0.001). Therefore, it seems possible, prospectively, among otherwise prognostically favorable patients, to select a group with high risk of recurrence which might benefit from adjuvant systemic therapy.

Localization of gastrinomas by transhepatic portal catheterization and gastrin assay.

Gastrinomas were localized by concurrent blood sampling in the hepatic vein and portal vein tributaries in 10 of 12 Zollinger-Ellison patients. In one patient, the portal vein could not be catheterized; in the other, a gastrin gradient could not be picked up in either of two examinations. Six of the patients were subsequently operated upon: 5 had pancreatoduodenal resection and 1 had laparotomy at which metastases were found. Four of the resections were probably curative as the patients have done well without treatment since with concentrations of gastrin in serum near zero. The observation period ranges from 17 to 20 mo. It is concluded that transhepatic catheterization of the hepatic vein and portal vein tributaries with blood sampling for gastrin determination permit the verification of the Zollinger-Ellison diagnosis and the localization of the gastrinomas. The latter may lead to the selection of a curative operative treatment in some of the patients.
