==Overview==
==Overview==
Ovarian carcinosarcoma, which is also known as a malignant mixed mullerian tumor (MMMT) of the ovary, is a rare, aggressive cancer of the ovary with two distinct characteristic cancer types i.e carcinoma and sarcoma.
Ovarian carcinosarcoma, which is also known as a [[malignant]] [[mixed mullerian tumor]] (MMMT) of the [[ovary]], is a rare, aggressive [[cancer]] of the [[ovary]] with two distinct characteristic [[cancer]] types i.e [[carcinoma]] and [[sarcoma]]. Primary ovarian sarcomas occur as pure sarcomas or [[Mixed mullerian tumor|mixed mullerian tumors]] (MMTs). Ovarian sarcoma is one of the least common [[Gynecologic Malignancies|gynecologic malignanc]]<nowiki/>y, constituting approximately 1% of all [[Ovarian malignancy|ovarian malignancies]]. [[Prognosis]] is generally poor, and the 5-year [[survival rate]] of [[patients]] with ovarian sarcoma is approximately 28.2%. Most of the [[women]] are [[asymptomatic]], when present, [[symptoms]] may include, [[pain]] in the [[abdomen]] or [[pelvic]] area, [[bloating]] or [[swelling]] of the [[abdomen]], quickly feeling full when [[eating]], other [[digestive]] problems. An elevated concentration of [[CA-125]] in [[serum]] is seen in some [[patients]] of ovarian sarcoma. [[Biopsy]] is the study of choice. Findings on [[MRI]] suggestive of ovarian sarcoma include the following. [[Surgery]] is the mainstay of treatment for ovarian sarcoma.Among all [[Chemotherapy regimens|chemotherapeutic regimens]] that are being used to treat ovarian sarcoma, they are divided into two groups like [[platinum]] containing regimens and non-platinum regimens. [[Cisplatin]], [[carboplatin]] are commonly used.

Overview

Ovarian carcinosarcoma, which is also known as a malignant mixed mullerian tumor (MMMT) of the ovary, is a rare, aggressive cancer of the ovary with two distinct characteristic cancer types i.e carcinoma and sarcoma. Primary ovarian sarcomas occur as pure sarcomas or mixed mullerian tumors (MMTs). Ovarian sarcoma is one of the least common gynecologic malignancy, constituting approximately 1% of all ovarian malignancies. Prognosis is generally poor, and the 5-year survival rate of patients with ovarian sarcoma is approximately 28.2%. Most of the women are asymptomatic, when present, symptoms may include, pain in the abdomen or pelvic area, bloating or swelling of the abdomen, quickly feeling full when eating, other digestive problems. An elevated concentration of CA-125 in serum is seen in some patients of ovarian sarcoma. Biopsy is the study of choice. Findings on MRI suggestive of ovarian sarcoma include the following. Surgery is the mainstay of treatment for ovarian sarcoma.Among all chemotherapeutic regimens that are being used to treat ovarian sarcoma, they are divided into two groups like platinum containing regimens and non-platinum regimens. Cisplatin, carboplatin are commonly used.

Pathophysiology

Differentiating ovarian sarcoma from Other Diseases

On the basis of age of onset, vaginal discharge, and constitutional symptoms, ovarian cancer must be differentiated from tubo-ovarian abscess, ectopic pregnancy, hydrosalpinx, salpingitis, fallopian tube carcinoma, uterine leiomyoma, choriocarcinoma, leiomyosarcoma, pregnancy, appendiceal abscess, appendiceal neoplasm, diverticular abscess, colorectal cancer, pelvic kidney, advanced bladder cancer, and retroperitoneal sarcoma.

  • Ovarian carcinosarcomas are aggressive neoplasms with a predilection towards early dissemination.
  • Prognostic factors for this tumor type remain unclear because of its rarity.

Treatment

Medical Therapy

There is no medical treatment for ovarian sarcoma, the mainstay of therapy is surgery and chemotherapy.

Surgery

  • Surgery is the mainstay of treatment for ovarian sarcoma.
  • The management is similar to that of epithelial carcinoma of ovary, consisting of cytoreductive surgery followed by adjuvant chemotherapy.

Chemotherapy

  • Chemotherapy with various regimens has been used in different centers without defined conclusions on efficacy[81][82][91][92][93]
  • Multiple chemotherapeutic regimens have been evaluated with modest response rates ranging from 12% to 100%.
  • Among all chemotherapeutic regimens that are being used, they are divided into two groups like platinum containing regimens and non-platinum regimens.
    • Platinum containing chemotherapy regimens
  1. Carboplatin and ifosfamide (Carbo-I)
  2. Carboplatin (Carbo)
  3. Cyclophosphamide, adriamycin and cisplatin (CAP)
  4. Carboplatin and cyclophosphamide (Carbo-C)
  5. Epirubicin, carboplatin and 5FU (E-Carbo-F)
  6. Epirubicin, cisplatin and 5FU (ECF)
  7. Taxol and Carboplatin (T-Carbo)
  • Other chemotherapy regimens
  1. Doxorubicin (A)
  2. Doxorubicin and cyclophosphamide (AC)
  3. Cyclophosphamide (IV)
