Rationale for using pathologic tumor dimensions and nodal status to subclassify surgically treated stage IB cervical cancer patients.

Between 1969 and 1988, 401 patients were treated by radical hysterectomy and pelvic lymphadenectomy for Stage IB cervical carcinoma at the University of Alabama at Birmingham. In multivariate analysis, pathological tumor diameter (P less than 0.0001) and the presence of lymph node metastasis (P = 0.0005) proved to be the dominant two histopathologic features that significantly correlated with overall survival. Although 5-year survival for the overall group was 85%, 5-year survival in patients with lesions greater than 3.0 cm in diameter and with regional nodal metastasis was less than 30%. This discrepancy in survival in surgically treated early-stage cervical cancer patients supports a need for subcategorization by risk factors such as pathologic tumor dimensions and nodal status and for further investigation of alternative neoadjuvant and adjuvant therapies in those early-stage cervical cancer patients deemed at high risk for poor overall survival.
