FIGO stage 1B2 cervical carcinoma--the KK Women's and Children's Hospital experience.

Introduction: The objectives of this review were to document the surgico-pathological characteristics of surgically resected FIGO stage 1B2 cervical carcinoma and to review our overall experience with this disease.

Materials And Methods: This is a retrospective review of 35 patients diagnosed and treated from September 1990 to November 2001.

Results: The median age was 42 years and the mean tumour diameter was 5.1 cm. Majority were squamous cell carcinomas (65.7%), 28.6% were adenocarcinomas and 5.7% were adeno-squamous carcinomas. The primary treatment comprised radical surgery in 77.1%, radiotherapy in 20% and neoadjuvant chemotherapy followed by radical surgery and adjuvant radiotherapy in 2.9%. Significant surgico-pathological features noted were deep stromal invasion (66.7%), lympho-vascular space invasion (55.6%), parametrial involvement (22.2%), positive margins (3.7%) and pelvic node metastases (33.3%). Postoperative radiation was given to 92.6% of the patients who underwent primary surgery, of whom 29% received concurrent chemotherapy. Radiation toxicity was mild with no grade 3 or 4 toxicity documented. For the patients who had surgery, the recurRence rate was 14.8% (11.1% pelvic and 3.7% distant) and the survival rate was 88.9%. For those who had primary radiation, the rate of persistent disease was 28.6%, the distant recurrence rate was 28.6% and the survival rate was 57.1%.

Conclusion: FIGO stage 1B2 cervical carcinomas are associated with significant rates of adverse surgico-pathological features. The ideal primary treatment is yet to be established and should be determined by prospective randomised trials.
