[The prognostic effect of scintigraphy-guided lymphadenectomy in therapy of stage Ib cervix carcinoma].
In a retrospective study the survival rates of 161 patients with stage Ib cervical cancer after radical operation (Latzko, Wertheim-Meigs) including complete or incomplete pelvine lymphadenectomy were compared. To increase radicality of lymphadenectomy, preoperative targeting of pelvic lymph nodes was done in all the patients using 99mTc-Sb2S3 radiocolloid. Intraoperatively, a gamma-camera being integral part of an operating table allowed delineation and scintigraphy-guided resection of pelvic lymph nodes. Dependent on the evidence of remaining pelvine foci of radioactivity at the end of the operation, lymphadenectomy was assessed as complete or incomplete. Mean observation time of completely lymphadenectomised patients (n = 117,72.67%) were 80 months (5-169 months) and 42 months (1-149 months) of the incompletely lymphadenectomised patients (n = 44,27.33%). In 28 (23.93%) completely lymphadenectomised patients against only 5 (11.36%) patients with incomplete lymphadenectomy, lymph node metastases were proved histologically. Five year-survival rate of completely lymphadenectomised patients was 85.47% and 88.64% of incompletely lymphadenectomised patients (not significant, Mantel-Test). Also, selective comparison of lymph node-positive patients did not suggest a divergent trend indicated by 13 (46.43%) deaths of completely and 3 (60.0%) deaths of the incompletely lymphadenectomised patients after an observation of five years. The technique of scintigraphy-guided pelvic lymphadenectomy using 99mTc-Sb2S3 radiocolloid cannot be expected to improve prognosis of patients with cervical cancer stage Ib.
