Abstract

Objective: To determine the association between pretreatment platelet count and survival in women with stage IB cervical cancer.

Methods: Clinical records were reviewed for 219 women with stage IB cervical cancer treated by radical hysterectomy from 1971-1984. Univariate and multivariate analyses were performed to identify clinicopathologic variables associated with poor survival. Survival as a function of the preoperative platelet count was analyzed further and corrected for known prognostic factors.

Results: The cumulative 5-year survival of women with a preoperative platelet count greater than 300,000/microL (n = 85) was 65%, as compared to 84% for a count equal to or less than 300,000/microL (n = 134) (P = .004). Univariate Cox regression analysis revealed non-white race, large lesion size (greater than 4 cm), platelet count greater than 300,000/microL, and the presence of nodal metastases to be factors related to poor prognosis. A comparison of patients with platelet counts of 300,000/microL or less and patients with platelet counts greater than 300,000/microL revealed no difference with regard to race, nodal metastases, and median age. However, a larger percentage of women with a platelet count greater than 300,000/microL had large lesion size (29 of 60, versus 32 of 114 with a count of 300,000/microL or less). In a multivariate analysis, after adjusting for age, race, the presence of nodal metastases, and lesion size, high platelet count was still associated with poor prognosis (P = .04).

Conclusion: An elevated platelet count is an independent prognostic factor for poor survival in patients with early-stage cervical cancer.
