title: Residual disease in the uterus after preoperative radiotherapy and hysterectomy in stage IB cervical carcinoma.
abstract: Sixty-one patients with FIGO IB cervical cancer treated with planned preoperative radiotherapy (dose to point A: 52-93 Gy, mean 73 Gy) and hysterectomy from 1969 to 1993 were retrospectively reviewed. Patient characteristics and treatment parameters and their association with residual tumor in the hysterectomy specimen were analyzed. Glandular (adenocarcinoma and adenosquamous) tumors were smaller than squamous tumors: 6/11 (55%) were < 6 cm in diameter, versus 12/50 (24%) squamous tumors (p = 0.03). Glandular tumors had a higher incidence of residual disease: 10/11 (91%) versus 24/50 (48%) (p = 0.01). There was no association between presence of pathologic residual disease in the hysterectomy specimen and tumor size, morphology (endophytic vs. exophytic), patient age, dose to point A, time to deliver radiotherapy, or interval between radiotherapy and hysterectomy. Overall 34/61 (56%) patients had residual disease in their hysterectomy specimens after planned preoperative radiotherapy. There were significantly more glandular tumors than squamous tumors with residual disease, even though glandular tumors were a group of smaller tumors.
