title: Comparison of Risk Factors and survival of Type 1 and Type II Endometrial Cancers.
abstract: OBJECTIVE
  To compare risk factors and progression free survival of type 1 & 2 endometrial cancers.
  
  
  METHODS
  A retrospective analysis of 149 patients with early stage endometrial carcinoma treated between 1997 and 2012 in Aga Khan University Hospital, Karachi was performed.
  
  
  RESULTS
  A total of 149 patients were analyzed. Type I tumors accounted for 92% of cases in the study while 8% were type II tumors. The mean age, BMI, parity, co-morbidities (hypertension & Diabetes), family history and history of polycystic disease were comparable in both groups. Overall better survival (113 Vs 24 months) was observed for type I endometrial cancer.
  
  
  CONCLUSIONS
  Both types of endometrial cancer may share common etiologic factors. Despite the limitation of small numbers in one group this study confirms better survival in type 1 endometrial cancer.
