EVALUATION OF SURGICAL TREATMENT FOR THE RETROPERITONEAL NEUROBLASTOMA WITH SPECIAL REFERENCE TO ABDOMINAL ANGIOGRAPHIC FINDINGS AND SERIAL URINARY VMA LEVELS

Abdominal aortographies were performed in 17 children with retroperitoneal neuroblastoma at the 1st Department of Surgery, Kyoto Prefectural University of Medicine. Urinary VMA and HVA were measured at the time of diagnosis in fifteen of the 17 patients. Nine patients of the 15 was assayed serially. The results in this study showed that complete removal of the tumor was able to perform easily with these angiographic findings such as capsule stain, no displacement of the aorta, no narrowing of the aorta and no parasitic blood supply. In contrast, the angiographic findings of displacement of the aorta, narrowing of the aorta, parasitic blood supply and A-V fistula indicated the difficulty of surgical removal.
The fifty percent survival duration of totally removed patients was 6 months and that of patients with only laparatomy was 3 months. The complete removal of neuroblastoma was favorable for survival duration.
The urinary VMA and HVA levels at the time of diagnosis did not reflect the prognosis. The serial measurement of urinary VMA was important on prognostic evaluation. The urinary VMA levels decreased in all patients who had recieved total removal of the tumor but elevated again coincidentally with the relapse. It is notable to point out that the decrease of urinary VMA into the normal range at the postoperative period and the level remaining within normal range for a long time were in 2 alived patients.
