title: The treatment of early stage cervical cancer: an assessment of pre-operative factors.
abstract: OBJECTIVE
  To assess the pre-operative clinical factors of a group of early stage cervical cancer patients and correlate them to the risk for adjuvant radiotherapy using GOG 92 and 109 criteria.
  
  
  METHODS
  A retrospective chart review of cervical cancer patients treated at the Saint Louis University Division of Gynecologic Oncology between the years 1989 and 2004 was performed. The results were compared with chi-squared testing and multivariable regression analysis. A p-value of 0.05 was considered significant.
  
  
  RESULTS
  One hundred and thirty-one cervical cancer patients underwent exploration for radical hysterectomy during the study time period. Five patients had stage IA1 disease, 6 patients had stage IA2 disease, 98 patients had stage IB1 disease, 20 patients had stage IB2 disease and one patient had stage IIA disease. No patient with stage IA1 or IA2 disease met criteria for adjuvant radiotherapy. The patients with stage IB1 tumors who were 45 years of age or younger and had tumors up to 2 cm in diameter had a low (14%) likelihood for treatment with adjuvant radiotherapy. The patients with stage IB1 tumors who were older than 45 years of age with tumors larger than 2 cm in diameter and the patients with stage IB2 tumors both had a high likelihood for adjuvant radiotherapy (77% and 90% respectively).
  
  
  CONCLUSIONS
  In our study group, the stage of cervical cancer and a combination of tumor diameter and patient age was found to stratify early stage cervical cancer patients by likelihood for adjuvant radiotherapy.
