RESUMO
BACKGROUND: hTFM in primary vulvar cancer is an important prognostic factor. Ideally, a diameter of > 8 mm should be achieved after primary surgery. The role of VIN III persistence after primary surgery in vulvar cancer is still unclear. The main objective of the current study was to study the role of residual VIN III re-excision and compare differences in disease-free survival among patients with different hTFM and in primary vulvar cancer. METHODS: Forty-two patients with residual adjacent VIN III after primary surgery for vulvar cancer which were operated between 2000 and 2016 in our clinic were enrolled in this retrospective study. Re-excision rates for residual adjacent VIN III were calculated. According to the histological margin patients were divided into three group: < 3, 3-8 and > 8 mm. Univariate and multivariate analyses were conducted using the Kaplan-Meier method and Cox proportional hazards models, respectively. RESULTS: The vast majority of patients had pT1b stage (57.1%), grading G2 (71.4%) and lymph node-negative (45.3%) disease at first diagnosis. The re-excision rate was 57.1%. The 5-year disease-free survival (DFS) rates in patients with < 3, 3-8 and > 8 mm hTFM were 50.0, 50.0 and 81.0%, respectively (p = 0.032). The 5-year DFS rates in patients with re-excision and without re-excision for VIN III were 77.3 and 52.9%, respectively (p = 0.060). In univariate analysis was solely hTFM > 8 mm a prognostic factor for DFS (p = 0.017). CONCLUSIONS: hTFM may be a potential prognostic indicator for DFS in vulvar cancer patients. Re-excision for residual adjacent VIN III could not be established as a prognostic factor for DFS after primary surgery in squamous cell cancer of vulva.

Myomas, also known as fibroids, are a specific characteristic of the human species. No other primates develop fibroids. At a cellular level, myomas are benign hyperplastic lesions of uterine smooth muscle cells. There are interesting theoretical concepts that link the development of myomas in humans with the highly specific process of childbirth from an upright position and the resulting need for greatly increased "expulsive" forces during labor. Myomas might be the price our species pays for our bipedal and highly intelligent existence. Myomas affect, with some variability, all ethnic groups and approximately 50% of all women during their lifetime. While some remain asymptomatic, myomas can cause significant and sometimes life-threatening uterine bleeding, pain, infertility, and, in extreme cases, ureteral obstruction and death. Traditionally, over 50% of all hysterectomies were performed for fibroids, leading to a significant healthcare burden. In this article, we review the developments of the past 20 years with regard to multiple new treatment strategies that have evolved during this time.

BACKGROUND/AIM: Totally implanted venous access devices (TIVAD) are increasingly used in the treatment of cancer patients. The aim of this study was to assess the incidence of early and late complications resulting from subcutaneous TIVADs in patients with breast cancer. MATERIALS AND METHODS: Between 2004 and 2009, we reviewed patients with breast cancer who had a TIVAD placed. Early and late complications, as well as risk factors for TIVAD-associated thrombosis were retrospectively assessed. RESULTS: A total of 281 patients were included. Complications occurred in 26% of patients, the majority of which were late complications (21.4%.) The development of TIVAD associated thrombosis was the most frequent late complication (16.4%). In the univariate analysis followed by a multivariate model, risk factors for TIVAD associated thrombosis were not identified. Only within the subgroup of metastatic breast cancer patients an increased risk of TIVAD-associated thrombosis of left compared to right venous access was detected (p=0.015). CONCLUSION: TIVAD implantation done in a gynecological outpatient setting is feasible and safe.

Borderline tumors (BOT) of the ovary account for 10% to 20% of ovarian neoplasms. Like ovarian cancer, BOT encompass several different histological subtypes (serous, mucinous, endometrioid, clear cell, transitional cell and mixed) with serous (SBOT) and mucinous (MBOT) the most common. Current hypotheses suggest low-grade serous carcinoma may develop in a stepwise fashion from SBOT whereas the majority of high grade serous carcinomas develop rapidly presumably from inclusion cysts or ovarian surface epithelium. The pathogenesis of mucinous ovarian tumors is still puzzling. Molecular markers could help to better define relationships between such entities. Trefoil factor-3 (TFF3) is an estrogen-regulated gene associated with prognosis in different types of cancer. It has also been included in a recent marker panel predicting subtypes of ovarian carcinoma. We analyzed the expression of TFF3 by immunohistochemistry in a cohort of 137 BOT and its association with histopathological features. Overall expression rate of TFF3 was 21.9%. None of the BOT with serous and endometrioid histology displayed strong TFF3 expression. On the other hand, TFF3 was highly expressed in 61.4% of MBOT cases and 33.3% of BOT with mixed histology (P < 0.001) suggesting a potential function of the protein in that subtypes. Associations of TFF3 expression with FIGO stage and micropapillary pattern were significant in the overall cohort but confounded by their correlation with histological subtypes. The highly specific expression of TFF3 in MBOT may help to further clarify potential relationships of tumors with mucinous histology and warrants further studies.

AIMS: Expression of Claudin-1 has been associated with prognosis in several cancers. Here we investigated the expression pattern of Claudin-1 in borderline tumours of the ovary (BOT). METHODS: We analysed a cohort of 114 cases of borderline tumour (BOT). Claudin-1 expression was studied by immunohistochemistry using a polyclonal antibody and was compared with clinical and histopathological characteristics. RESULTS: Strong Claudin-1 expression was found in 30 cases (26.3%) independent of histological subtype. Expression was significantly less frequent in International Federation of Gynecology and Obstetrics (FIGO) stage I (p= 0.045), while the presence of microinvasion did not correlate with Claudin-1 expression. In contrast, we detected a highly significant association of Claudin-1 expression with the presence of peritoneal implants (p=0.003) and micropapillary pattern (p=0.047), which are features exclusively seen in serous BOT. Moreover, when we restricted our analysis to the subtype of serous BOT, the association of Claudin-1 expression with peritoneal implants (p<0.001) and micropapillary pattern (p =0.003) remained highly significant. CONCLUSIONS: In conclusion, Claudin-1 expression is associated with the presence of peritoneal implants and micropapillary pattern, which have been shown to be associated with poor prognosis. We speculate that overexpression of Claudin-1 might be linked to the mitogen-activated protein kinase pathway activation in BOT and suggest further studies to define its prognostic and potential therapeutic value.

AIM: To gather standardized information of current perioperative management of gynecological oncology patients and to evaluate up to what extent the Enhanced Recovery after Surgery (ERAS) elements are established in the clinical routine of gynecologic oncology units in Germany. MATERIALS AND METHODS: We performed a multi-centric nationwide survey among 654 primary, secondary and maximal health care gynecological departments in Germany. A multiple-choice questionnaire based on the principles of ERAS was developed to gather information about perioperative management of two fictional cases in gynecological oncology. RESULTS: One hundred four units (22%) have been taken the survey. Only 49.5% of surveyed hospitals claimed to be adherent to more than 70% of ERAS elements in managing perioperative period of primary cytoreductive surgery in ovarian cancer patients. 21% of these hospitals implemented more than 80% and only 8.4% implemented more than 90%. The results in border-line tumors operations did not differ from those of ovarian cancer operations. CONCLUSION: The implementation of ERAS elements in gynecologic oncology in Germany is still not satisfying as only half of the departments will now be able to apply 70% of these principles. Therefore, we plan the second step of this survey in order to be able to build a consistent structured reporting platform between gynecological oncology units in Germany to facilitate the wide implementation and standardization of ERAS protocol.
