ABSTRACT
Objective To investigate the metastatic risk factors of pelvic lymph nodes in patients with cervical carcinoma of stage Ia2 and IIa2.Methods The clinic opathologicparameters in 337 patients with stage Ia2 -IIa2 cervical carcinoma were retrospectively analyzed,and were studied the related factors of pelvic lymph node metastasis.Results The lymph nodes metastasis rate was 11.87%,with the obturator and internal iliaclymph nodes mostly involved.Multivariate analysis showed that the myometrial invasion,size of tumor,lymph -vascular space involvement and utero -tissue infiltration were major risk factors.The OR value and 95%CI were 3.464(1.502 -7.985)、4.316 (1.164 -7.833)、6.167 (2.592 -14.674)和 8.507(1.966 -36.808)respectively.Conclusion The myometrial invasion≥ 2 /3,size of tumor≥ 4 cm, lymph -vascular space involvement and utero -tissue infiltration positive lymph node metastasis of cervical cancer are easy to occur.
