title: Identifying local tumor variables for operable node-negative, margin-free patients with bulky cervical carcinoma of FIGO stage IB, IIA and IIB without adjuvant therapies.
abstract: OBJECTIVE
  To identify local risk factors for FIGO IB, IIA and IIB bulky cervical squamous cell carcinoma (tumor size > or = 4 cm) patients with node-negative, margin-free tumors treated by radical hysterectomy, pelvic lymph node and para-aortic lymph node dissections without adjuvant therapies.
  
  
  METHODS
  Thirty-four patients were recruited between 1976 and 1989 because they all declined any postoperative adjuvant therapy. The pathology reports showed that all the specimen margins were free from cancer cells with no para-aortic or pelvic lymph node metastases. The survival interval was calculated starting from the time of surgical intervention to the time of death or the end of this study in the year 2000.
  
  
  RESULTS
  Tumor variables including cell differentiation, depth of stromal invasion, parametrial invasion, vaginal invasion, uterine body invasion, age, and FIGO stage were analyzed. Only vaginal invasion showed statistical significance for decreasing patient disease-free survival in both univariate and multivariate analyses with p values of 0.003 and 0.002, respectively.
  
  
  CONCLUSIONS
  For node-negative and margin-free patients with bulky cervical squamous cell carcinoma with operable stage IB and IIB, surgical intervention alone could suffice when no vaginal invasion is noted plus an 85% survival rate could be achieved. A prospective pilot study should be initiated although this study showed an excellent survival rate which is perhaps due to the limited number of cases.
