Ovarian Cancers : Advances through International Research Cooperation (G Bok Ductal Carcinoma In Situ and Microinvasive/Borderline Breast Cancer.

In contrast to invasive epithelial ovarian cancers, borderline tumors are more likely to occur in premenopausal women and are more likely to be stage I, or confined to the ovaries at presentation. When borderline ovarian tumors are confined to the ovaries, long-term survival approaches 100%. Serous and mucinous borderline ovarian tumors are the two most common types, while endometrioid, Brenner, and clear cell borderline ovarian tumors are much less common. The term “seromucinous” has a confusing name, but merely refers to a tumor of mixed epithelial types (i.e. serous, mucinous, endometrioid, etc.).

Ovarian borderline tumors have also been referred to as “tumors of low malignant potential” or “atypical proliferative tumors”; however “borderline tumor” is the preferred terminology. Borderline tumors exhibit epithelial proliferation and cytologic atypia, beyond that acceptable for a benign neoplasm, but do not exhibit the destructive growth seen in carcinomas.

Background . Serous borderline tumor represents a group of noninvasive tumor of the ovary bridging between benign serous cystadenoma and serous carcinoma. They are commonly seen in younger women and usually have an excellent outcome but seldom show local recurrence (J. F. Leake et al. 1991).

This article will help you to understand the diff erences and how to distinguish borderline lesions from other types of lesions. Borderline ovarian tumors Borderline ovarian tumors (BOT) were first described in 1929 by Taylor, which, due to the characteristics of the tumor, called it “semi malignant” or “borderline” ; subsequently, this group of tumors of the ovary were classified in 1973 by the World Health Organization as “low malignant potential ovarian tumor” and, finally, in 2003 WHO separates them from carcinomas and call them Borderline ovarian tumors (BOT) were first described in 1929 by Taylor, which, due to the characteristics of the tumor, called it “semi malignant” or “borderline” [1]; subsequently, this group of tumors of the ovary were classified in 1973 by the World Health Organization as “low Applies to primary borderline tumors, carcinomas, germ cell tumors, and sex-cord stromal tumors only Based on AJCC/UICC TNM, 6th edition and FIGO 2001 Annual Report OVARY: Oophorectomy, Salpingo-oophorectomy, Subtotal Oophorectomy or Removal of Tumor in Fragments, Hysterectomy with Salpingo-oophorectomy Note: Applies to ovarian primary tumor. Therefore, borderline mucinous ovarian tumor with microinvasion is not reportable. Low malignant potential/borderline ovarian tumors are defined by the pathology of the primary tumor in the ovary, and microinvasion there, or invasion in implants does not change that diagnosis. 2018-03-21 Borderline tumors tend to develop in an exophytic growth pattern, on the surface of the ovary, without invading the underlying stroma. Papillary projections are characteristic of and are often abundant in epithelial tumors with low malignant potential, whereas they are not typically seen, or are insignificant, in benign cystadenomas.

Ovarian serous borderline tumor (SBT) is a low grade epithelial neoplasm of generally younger women with a favorable prognosis when diagnosed at an early stage Defined, nonobligate precursor to low grade serous carcinoma (LGSC) As a borderline tumor, can give rise to extra-ovarian abdominoperitoneal or lymph node implants Borderline tumors of the ovary (also called tumors of low malignant potential) are a heterogeneous group of lesions defined histologically by atypical epithelial proliferation without stromal invasion [ 1 ]. The behavior of these tumors is distinct from low-grade ovarian carcinoma, and they are considered a distinct clinical entity. In contrast to invasive epithelial ovarian cancers, borderline tumors are more likely to occur in premenopausal women and are more likely to be stage I, or confined to the ovaries at presentation.

Borderline ovarian tumors (BOT) are uncommon but not rare epithelial ovarian neoplasms, intermediate between benign and malignant categories. Since BOT were first identified >40 years ago, they have inspired controversies disproportionate to their incidence. Borderline ovarian tumors represent a heterogeneous group of noninvasive tumors of uncertain malignant potential with characteristic histology. They occur in younger women, are present at an early stage, and have a favorable prognosis, but symptomatic recurrence and death may be found as long as 20 years after therapy in some patients.

2021-01-01 · Borderline Ovarian Tumors (BOTs) are believed to account for 10%–20% of all epithelial tumors of the ovary. Their particularity is that they occur on average 10 years earlier and have a much better prognosis than ovarian carcinomas. The two main histological forms of BOTs are serous and mucinous. 2021-03-02 · Home Gynecologic Ovary Mucinous Ovarian Tumors Mucinous Ovarian Tumors Mucinous Intraepithelial Carcinoma in Mucinous Borderline Tumor.
