Overview

Classification

General Classification

  • Epithelial ovarian tumors can broadly be classified on the bases of histopathology and clinical behavior as:
    • Benign
    • Borderline
    • Malignant tumors
  • Table below provides a summary of this classification:
Epithelial ovarian tumors
Benign Borderline Malignant
  • Serous cystadenoma
  • Mucinous cystadenoma
  • Endometrioid cystadenoma
  • Clear cell tumor
  • Brenner tumor
  • Serous borderline tumor
  • Mucinous borderline tumor
  • Endometrioid borderline tumors
  • Clear cell tumor
  • Brenner tumor of borderline malignancy
  • Serous adenocarcinoma
  • Mucinous adenocarcinoma
  • Endometrioid adenocarcinoma
  • Clear cell adenocarcinoma
  • Malignant Brenner tumor
  • Carcinosarcoma

WHO Classification of Ovarian Epithelial Tumors

  • WHO classifies epithelial ovarian tumors on the basis of histology as follows:
    • Serous tumors:
      • Benign (cystadenoma)
      • Borderline tumors (serous borderline tumor)
      • Malignant (serous adenocarcinoma)
    • Mucinous tumors:
      • Benign (cystadenoma)
      • Borderline tumors (mucinous borderline tumor)
      • Malignant (mucinous adenocarcinoma)
    • Endometrioid tumors:
      • Benign (cystadenoma)
      • Borderline tumors (endometrioid borderline tumor)
      • Malignant (endometrioid adenocarcinoma)
    • Clear cell tumors:
      • Benign
      • Borderline tumors
      • Malignant (clear cell adenocarcinoma)
    • Transitional cell tumors:
      • Brenner tumor
      • Brenner tumor of borderline malignancy
      • Malignant Brenner tumor
      • Transitional cell carcinoma (non-Brenner type)
    • Epithelial-stromal:
      • Adenosarcoma
      • Carcinosarcoma (formerly mixed Müllerian tumors)

Epithelial Ovarian Cancer Classification Based on Clinicopathologic and Molecular Evidence

  • Recent advances in histopathology and a better understanding of clinicopathologic characteristics have led to a classification system that correlates histology and clinical characteristics;
  • This classification subdivides malignant ovarian tumors in two types.
  • Type I tumors generally arise from endometriosis or fallopian tubal related serous epithelium. They exhibit less aggressive clinical course and a different genetic profile relative to Type II.
  • Type II tumors generally arise from fallopian tubal epithelium. They exhibit more aggressive clinical course and a different genetic profile relative to Type I.
Epithelial Ovarian Cancer
Type I Type II
  • Low-grade serous carcinoma
  • Endometrioid carcinoma
  • Clear cell carcinoma
  • Mucinous carcinoma
  • Malignant Brenner tumor
  • Seromucinous carcinoma
  • High-grade serous carcinoma
  • Undifferentiated carcinoma
  • Carcinosarcoma
