Clinico-pathological spectrum of primary ovarian malignant mixed mullerian tumors (OMMMT) from a tertiary cancer institute: A series of 27 cases.
OBJECTIVE
To study the clinico-pathological characteristics of primary ovarian malignant mixed mullerian tumor (OMMMT) and assess the prognostic factors associated with treatment outcome and survival.


METHODS
The pathology database was searched for primary ovarian carcinosarcoma diagnosed and/or managed at our institute from period of January 2004 to July 2010. The histological sections were reviewed, with emphasis on type and grade of epithelial and sarcomatous components. The medical records were retrospectively analyzed for clinical details and follow up.


RESULTS
A total of 27 cases of primary ovarian carcinosarcoma were identified. The median age at diagnosis was 51 years. Fourteen patients had advanced stage (stage III and IV) at presentation. Cytoreductive surgery was done in 18 cases, and 7 had received upfront chemotherapy. Histologically, 10 cases had epithelial predominance (> 50% epithelial component) and 11 had sarcoma predominance. The most frequent epithelial component was endometroid type, and most common sarcoma component was rhabdomyosarcomatous. Hyaline droplets within sarcomatous stroma were seen prominently in 15 cases. Three cases showed germ cell /yolk sac-like areas. Eighteen cases had follow up with a median of 15 months (4-40 months). The recurrence-free survival in advanced stage and sarcoma predominant was 10.5 months in comparison to 13 months in early stage and epithelial predominant OMMMT.


CONCLUSIONS
Primary ovarian carcinosarcoma is a rare biphasic malignancy with variable proportions of epithelial and spindle elements. Presence of hyaline droplets within spindle sarcoma in a biopsy from ovarian mass should alert the pathologists regarding MMMT. Advanced stage, suboptimal cytoreduction, and sarcoma predominant tumors are likely to have a worse outcome in ovarian MMMT.
