Vagina invasion by cervical carcinoma.
Seventy patients with cervical carcinoma who underwent radical hysterectomy and pelvic lymphadenectomy were evaluated to assess spread to the vagina. The overall vaginal invasion rate was 34.2% (24/70), with 36% (21/58) by squamous cell carcinoma, 25% (2/8) by adenocarcinoma and 25% (1/4) by adenosquamous carcinoma. A high vaginal invasion rate (45.7%) was noted in cases in which the cervical lesion was greater than 21 mm (p less than 0.05). Combined parametrial extention (45%) and combined lymph node metastasis (33.3%) were significantly higher in the vaginal invasion cases. The diagnostic accuracy of colposcopy and the Schiller test was 80% and 67% respectively. Histologically, the course of vaginal invasion by squamous cell carcinoma could be divided into : a) continuous invasion (16/21), b) incontinuous invasion via vessel permeation (3/21) and c) combined invasion (2/21). Both cases of vaginal invasion by adenocarcinoma were noted to spread by vessel permeation. Of the 7 cases of vessel permeation, colposcopic examination was positive in only one case. A high percentage of parametrial involvement and lymph node metastasis was noted in the vessel permeation type.
