[The association of lymph nodes scintigraphy with 99Tcm-sulfur-microcolloid and ultrasounds scan in stage diagnosis of lymphomas (author's transl)].

Thirty seven patients with lymphomatous disease were studied to detect abdominal lymph nodes involvement by means of lymph nodes scan with 99Tcm-sulfur-microcolloid, ultrasounds scans, lymphangiographies. Lymphangiography was considered as reference standard in patients which explorative laparotomy was not performed in. Isotopic method demonstrated high sensitivity, despite low specificity. Opposite results were obtained by ultrasounds. We concluded that isotopic abdominal lymph nodes scan is a clinically valuable test, if negative, while ultrasounds are, if positive. Both methods, specially if associated, proved quite useful in restaging after therapy, where important parameters are low risk and stress for the patients, easy execution, low costs.
