Pelvic lymphoscintigraphy with 99mTc-colloid in lymph node metastases.

Twenty-four patients with cervical cancer stage Ib were examined by pelvic lymphoscintigraphy with 99mTc-colloid prior to operation. Four of the patients had histologically verified lymph node metastases. No difference in the lymphoscintigrams was found between the patients with pelvic metastases and those without. The removed involved lymph nodes did not contain less radioactive colloid than the histologically normal nodes. In two involved lymph nodes the uptake of radioactivity was far above any of the noninvolved nodes.
