1 Mar 2012 In 12 series of serous borderline ovarian tumours with microinvasion (n=133), 20 patients had recurrence (15%), including 35% (seven of 20)

Some studies conclude that serous borderline tumors with microinvasion have a similar prognosis to that of the normal serous borderline tumor [2, 12,19], and conserving the contralateral ovary and typical serous borderline tumors with stromal microinvasion (14.2%). In one case, the microinvasion was of eosinophil type, and in the other case it had a glandular and micropapillary pattern associated with noninvasive peritoneal implants. The histological characteristics of stromal microinvasion in serous borderline tumors have It has been suggested that microinvasion in M-BOTs should be classified into two categories: borderline tumor with microinvasion and borderline tumor with microinvasive carcinoma . Foci of microinvasive carcinoma are of uncertain prognostic significance; when they are present, however, pathologists should search intensively for larger foci of invasive carcinoma. Objective The aims of this study were to evaluate the rate of recurrences in borderline ovarian tumors (BOTs) with microinvasion and to evaluate the possibility to enlarge fertility-sparing surgery in this group of patients. Borderline tumors with intraepithelial carcinoma and/or microinvasion provide evidence that these tumors form a morphologic spectrum with individual types representing steps in the sequence of mucinous carcinogenesis in the ovary . Cytologic atypia in microinvasion is mild to moderate, similar to adjacent borderline 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. Borderline ovarian tumor. Borderline ovarian tumours differ from epithelial ovarian cancer by their low incidence, frequent association with infertility, low association with mutations in BCRA genes, different percentages of the most common histological types, early stage diagnosis, and high survival rate, even when associated with peritoneal involvement. The histologic criteria for the diagnosis of borderline ovarian tumors include nuclear atypia, stratification of the epithelium, formation of microscopic papillary projections, and the absence of stromal invasion. 1 In the same way that invasive ovarian cancer is divided into different histologies, borderline tumors are also divided into different histologic subtypes.

21 Although often asymptomatic, the tumor may sometimes present with abdominal enlargement and pain due to rupture or torsion. . Approximately 70% are confined to one or both In one report, 44 "mucinous borderline tumor with microinvasion" is used for those tumors lacking intraepithelial carcinoma, and "mucinous borderline tumor with microinvasive carcinoma" is used for those containing intraepithelial carcinoma.

Some studies conclude that serous borderline tumors with microinvasion have a similar prognosis to that of the normal serous borderline tumor [2, 12,19], and conserving the contralateral ovary and

Mucin extravasation with inflammatory response and histiocytes is associated with gland rupture and not diagnostic of microinvasion. Borderline ovarian tumors (BOTs), or low malignant po-tential tumors, represent a rare and special tumor entity.1 They are epithelial tumors of the ovaries characterized by cellular proliferation and nuclear atypia but without an in-filtrative growth pattern.2 A subgroup of BOTs presents microinvasion, a histological feature characterized by the borderline tumor with microinvasion, were discussed [2]. However, the nomenclature and diagnostic criteria of M-BOT remain controversial. We report the case of a We examined a series of 171 intestinal-type mucinous tumors of low malignant potential (“borderline” or “atypical proliferative” tumors) to clarify the clinical significance of intraepithelial carcinoma (IECA) and microinvasion (area ≤10 mm 2). The diagnosis of IECA was based on the presence of marked nuclear atypia (grade 3). Borderline is usually treated with surgery and followup.

Home · Målriktad behandling ett Clinical significance of microinvasion in borderline ovarian tumors and its impact on surgical management Although exploratory, our data suggest that BOTs with microinvasion present earlier relapses, but overall incidence of relapses and overall survival do not differ significantly from BOTs without microinvasion. Microinvasion, invasive implants and recurrences all showed qualitative histologic resemblance to carcinoma.

invasion of < 5 mm in greatest dimension is deﬁned as microinvasion, regardless of number of foci; tumors with microinvasion are considered SMBT (“SMBT with microinvasion”). 2018-08-01 Two of 13 (15%, 95% CI 8.7, 21.3) patients with microinvasion died of recurrent invasive cancer, whereas only 1 out of 113 patients without microinvasion died of recurrent borderline tumor (OR 20.4, 95% CI 1.2, 239). All 3 patients with an aggressive disease course and poor outcome had increasing CA 125 levels at the time of recurrence.

In these tumors, the microinvasive component with marked cellular atypia is classified as microinvasive carcinoma. A tumor stage ≥IC, intraepithelial carcinoma, microinvasion, and patient age of less than 45 years are associated with Ovarian mucinous borderline tumours of intestinal type – a pathologist’s perspective. ‘Mucinous tumors of ovary are among the most difficult ovarian neoplasms for surgical pathologists to interpret.’ Hart WR.1 Mucinous tumours of the ovary comprise an estimated 10–15 per cent of all primary ovarian epithelial tumours. These tumours are characterised by mucinous differentiation of the Borderline Ovarian Serous Neoplasm with Microinvasion; Borderline Ovarian Serous Tumor with Microinvasion Definition A low grade ovarian epithelial neoplasm characterized by the presence of neoplastic serous epithelial cells, atypia, and microinvasion of the ovarian stroma.

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.
