Abstract

BACKGROUND:

Surgical-pathological risk factors were evaluated by weighting the magnitude of significance of multiple risk factors correlating to survival and treatment response in cervical cancer.

METHODS:

Multivariate analysis was performed for survival outcomes entering seven pathological factors obtained from 540 radical hysterectomy specimens in stage IA2-IIB cervical cancer cases. Hazard ratio (HR) in each risk factor was determined, and the sum of HR scores for the corresponding risk factors was determined per case. Survival curves and postoperative treatment response (concurrent chemoradiotherapy (CCRT) vs radiotherapy alone) were evaluated based on the extent of HR-weighted scores.

RESULTS:

Hazard ratios for risk factors relating to disease-free survival (DFS) was: lympho-vascular space invasion 3.95, nodal metastasis 3.88, adenocarcinoma 3.40, large tumour 2.36, positive margin 1.99, deep stromal invasion 1.29, and parametria invasion 1.21. The HR-weighted scoring method showed a high predictive value for recurrence (area-under-curve 0.836, P<0.001). Hazard ratio-weighted scores were negatively correlated to DFS, and the cases with score 12.5 showed 5-year DFS rate of 23.8%. Tumours with larger score offset the benefits of CCRT over radiotherapy alone for postoperative adjuvant treatment (P<0.001).

CONCLUSION:

Surgical-pathological risk factors provide valuable information for survival and management of early-stage cervical cancer when number and significance of risks are weighted.
