ā“˜ Ovarian tumor

Ovarian cancer is classified according to the histology of the tumor, obtained in a pathology report. Histology dictates many aspects of clinical treatment, management, and prognosis.

  • Mixed tumors, containing elements of more than one of the above classes of tumor histology.
  • Sex cord-stromal tumor, including estrogen-producing granulosa cell tumor and virilizing Sertoli-Leydig cell tumor or arrhenoblastoma, accounts for 8% of ovarian cancers.
  • Surface epithelial-stromal tumours, also known as ovarian epithelial tumors, are the most common type of ovarian cancer. It includes serous tumour, endometrioid tumor, and mucinous tumour. They can be benign cystadenoma or malignant cystadenocarcinoma. Less common tumors are malignant Brenner tumor and transitional cell carcinoma of the ovary.
  • Germ cell tumor accounts for approximately 30% of ovarian tumors but only 5% of ovarian cancers, because most germ cell tumors are teratomas and most teratomas are benign. Germ cell tumors tend to occur in young women 20sā€“30s and girls. Whilst overall the prognosis of germ cell tumors tend to be favourable, it can vary substantially with specific histology: for instance, the prognosis of the most common germ cell tumor dysgerminomas tends to be good, whilst the second most common endodermal sinus tumor tends to have a poor prognosis. In addition, the cancer markers used vary with tumor type: choriocarcinomas are monitored with beta-HCG, dysgerminomas with LDH, and endodermal sinus tumors with alpha-fetoprotein.
                                     
  • epithelial - stromal tumors are a class of ovarian neoplasms that may be benign or malignant. Neoplasms in this group are thought to be derived from the ovarian surface
  • Mucinous tumors are part of the surface epithelial - stromal tumor group of ovarian neoplasms, and account for approximately 36 of all ovarian tumors Approximately
  • epithelial ovarian tumors Cord - stromal and germ cell belong to the nonepithelial category which are much less common. According to research, most ovarian cancers
