title: A review of prognostic factors in early-stage carcinoma of the cervix (FIGO I B and II A) and implications for treatment strategy.
abstract: Several prognostic factors in stages I B and II A cervical carcinoma have been widely studied to define groups of patients with a poor prognosis. Most of these factors are interrelated. The characteristics which should be regarded as main factors have not yet been defined, because the studies reported were based on mainly retrospective and non-randomized analysis. Reviewing the literature, lymph node metastasis, differentiation grade, tumor size, parametrial extension, lymph-blood vessel invasion and cervical invasion seem to be prognostically important factors, which suggests that the subdivision of patients according to the FIGO classification alone is inaccurate. It seems useful to define subgroups of patients according to tumor characteristics, determined after surgical treatment and accurate histologic examination of the surgical specimen. Patients with one or more of these tumor features need additional treatment to improve survival. The current treatment modalities, such as postoperative radiotherapy, have not been thoroughly evaluated, but doubt exists as to their efficacy. Data in the literature suggest that particularly patients with para-aortic or multiple pelvic lymph node metastasis (greater than 3) have already developed distant metastases at the time of primary treatment and therefore need adjuvant systemic therapy. Patients with tumors larger than 4 cm in diameter, differentiation grade III, lymph-blood vessel invasion or cervical invasion (of more than 70%) seem to have high recurrence rates at both pelvic and distant sites, indicating that there is also a need for better pelvic control.
