RESUMO

OBJECTIVE: The aim of this study was to compare the power of preoperative transvaginal ultrasonography, intraoperative macroscopic examination, and frozen section for predicting deep myometrial invasion in endometrial cancer. METHODS: This is a retrospective review involving 68 patients who underwent surgical staging for endometrial cancer from 2014 to 2017. Patients with grade 3 endometrial cancer and non-endometrioid tumors were excluded. The findings related to preoperative transvaginal ultrasonography, intraoperative macroscopic examination, and frozen section were compared with definitive histopathological diagnosis. RESULTS: The mean age, gravidity, and body mass index of the patients were 58.1±8.9 years (range: 30-80 years), 3.2±2.1 (range: 0-9), and 33.5±6.6 kg/m2 (range: 20-52 kg/m2), respectively. Only 11 (16.2%) patients were in the premenopausal period, while 57 (83.8%) were in the postmenopausal period. Grade 1 endometrial cancer was found in 29 patients (42.6%) and grade 2 tumors were specified in 39 patients (57.4%). Stage IA disease was found in 45 (66.2%) patients, while stage IB disease was observed in 23 (33.8%) patients. The 5-year survival rate was 91.2%. The sensitivity of preoperative transvaginal ultrasonography, intraoperative macroscopic examination, and frozen section were 56, 34, and 52%, respectively, for predicting deep myometrial invasion. In contrast, the specificity of preoperative ultrasonography, intraoperative macroscopic examination, and frozen section were 86, 100, and 100%, respectively. CONCLUSION: Transvaginal ultrasonography and intraoperative frozen section were found to have similar sensitivity and specificity for predicting deep myometrial invasion. Preoperative transvaginal ultrasonography appears as an efficient approach for predicting endometrial cancers with deep myometrial invasion.

RESUMO

OBJECTIVE: Surgical management is essential in early-stage vulvar squamous cell carcinoma (SCC), but these surgical procedures often cause significant morbidity. Immunotherapy may be a new treatment option in these patients. FoxP3+ Tregs suppress anti-tumor immune responses. High intratumoral FoxP3+ Treg infiltration has been reported to be associated with poor prognosis in most solid tumors. However, there are also conflicting results. We evaluated FoxP3+ lymphocyte infiltration in vulvar SCC and aimed to determine its relationship with prognosis and clinicopathological parameters. METHODS: Cases diagnosed with vulvar SCC in our department were retrospectively reviewed. The paraffin block that best reflects the morphology was selected, and immunohistochemical studies were performed in accordance with the manufacturer's instructions. FoxP3+ lymphocyte counts were made in tumoral stroma and within tumoral cell islands separately in hot-spot areas. RESULTS: We found a positive correlation between high FoxP3+ lymphocyte count and good prognostic parameters. There was less recurrence in the group with high FoxP3+ lymphocyte counts in tumoral cell islands. Overall survival was not statistically different between these groups. Less lymphovascular invasion was observed in the group with high lymphocyte count in the tumoral stroma. CONCLUSION: In vulvar SCC, FoxP3+ Treg infiltration into the tumor stroma and into tumoral cell islands is associated with good prognostic features. In these tumors, stage appeared as the only independent prognostic parameter. Studies to be conducted in larger series may reveal whether Tregs can be targeted in cancer treatment.

RESUMO

BACKGROUND/AIM: The purpose of this study was to prove the effect of complete surgical staging of patients with mucinous borderline ovarian tumors (mBOTs) especially appendectomy on progression-free survival (PFS) and overall survival (OS). PATIENTS AND METHODS: The database of 14 gynecological oncology departments from Turkey and Germany were comprehensively searched for women who underwent primary surgery for an ovarian tumor between January 1, 1998, and December 31, 2015, and whose final diagnosis was mBOT. RESULTS: A total of 364 patients with mBOT with a median age of 43.1 years were included in this analysis. The median OS of all patients was 53.1 months. The majority of cases had Stage IA (78.6%). In univariate and multivariate analyses, radical surgery, omentectomy, appendectomy, lymphadenectomy, and adding adjuvant chemotherapy were not independent prognostic factors for PFS and OS. Furthermore, FIGO stage (≥IC vs.

RESUMO

Gestational Trophoblastic Neoplasia (GTN) is a term used for a group of malignant gynecological tumors including choriocarcinoma. Low-risk neoplasias can be cured using single agents Methotrexate (MTX) and actinomycin-D (ACD), but in certain cases, decreased responsiveness and serious side effects occur. Therefore, researchers have been attempting to find new treatment modalities. One of the most popular way for increasing cancer patient survival rates is supporting treatment with adjuvant molecules or chemosensitizers. For this purpose, we investigated epigallocatechin-3-gallate (EGCG), a green tea cathecin, and Erlotinib, an EGFR tyrosine kinase inhibitor, as single agents and combined with MTX or ACD. In accordance with this, JAR (human placenta choriocarcinoma) cell line was used as an in vitro model and MTT, LDH, caspase-3 activation, RT-PCR, and Western Blot analyses were performed to investigate the effects of the test materials. Our studies demonstrate that combination of Erlotinib and EGCG with MTX and ACD decreases JAR cell proliferation and metastatic HER2 protein synthesis and increases caspase-3 activation compared to ACD or MTX alone. In addition, significant increase was observed in the apoptotic Bax gene, but no notable protein synthesis occurred in the Western Blot analysis, which suggests that combination of Erlotinib and EGCG with classical chemotherapeutics ACD or MTX may lead the JAR cells to apoptosis, but not by a mitochondrial pathway. All the results indicate that the synergetic effect of Erlotinib and EGCG with classical chemotherapeutics may help to increase patient survival rates of choriocarcinoma, but the detailed mechanism needs further investigation.

RESUMO

INTRODUCTION: We compared the disease free-survival (DFS) and overall survival (OS) rates of patients with high-grade serous primary fallopian tube cancer (HG-sPFTC) and high-grade serous epithelial ovarian cancer (HG-sEOC). METHODS: 22 early-stage cancer patients (International Federation of Gynecology and Obstetrics (FIGO) stages I-II) with HG-sPFTC were retrospectively evaluated. In addition, 44 control patients diagnosed with HG-sEOC were matched to these patients with respect to tumor stage at diagnosis. All patients underwent complete surgical staging, followed by adjuvant chemotherapy. Kaplan-Meier curves were used to generate survival data. RESULTS: The mean age of HG-sPFTC patients was 59.4 ± 6.2 years, and that of HG-sEOC patients 55.2 ± 11.0 years (p = 0.002). All patients underwent 6 cycles of platinum-based adjuvant chemotherapy. All operations were optimal. The 5-year DFSs were 77.3% for HG-sPFTC patients and 75% for HG-sEOC patients (p = 1.00).The 5-year OS rates were 81.8% in women with HG-sPFTC and 77.3% in those with HG-sEOC (p = 0.75). CONCLUSION: The DFS and OS rates of patients with early-stage (FIGO stages I and II) HG-sPFTC and HG-sEOC were similar. The surgical and adjuvant therapy management of these malignancies should be similar.

RESUMO

PURPOSE: The purpose of this study is to evaluate the prognostic role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) and the need for para-aortic lymphadectomy in patients with primary fallopian tube carcinoma (PFTC). MATERIALS AND METHODS: Ninety-one patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of six academic centers. Clinicopathological, surgical, and complete blood count data were collected. RESULTS: In univariate analysis, advanced stage, suboptimal surgery, and NLR > 2.7 were significant prognostic factors for progression-free survival, whereas in multivariate analysis, only advanced stage and suboptimal surgery were significant. In addition, in univariate analysis, cancer antigen 125 ≥ 35 U/mL, ascites, advanced stage, suboptimal surgery, NLR > 2.7, PLR > 233.3, platelet count ≥ 400,000 cells/mm(3), staging type, and histological subtype were significant prognostic factors for overall survival (OS); however, in multivariate analysis, only advanced stage, suboptimal surgery, NLR > 2.7, and staging type were significant. Inclusion of pelvic and para-aortic lymphadenectomy in surgery showed significant association with longer OS, with a mean and median OS of 42.0 months and 35.5 months (range, 22 to 78 months), respectively, vs. 33.5 months and 27.5 months (range, 14 to 76 months), respectively, for patients who underwent surgery without para-aortic lymphadenectomy (hazard ratio, 3.1; 95% confidence interval, 1.4 to 5.7; p=0.002). CONCLUSION: NLR (in both univariate and multivariate analysis) and PLR (only in univariate analysis) were prognostic factors in PFTC. NLR and PLR are inexpensive and easy tests to perform. In addition, patients with PFTC who underwent bilateral pelvic and para-aortic lymphadenectomy had longer OS.

RESUMO

PURPOSE: The purpose of this study is to evaluate the clinicopathological characteristics, treatment, and prognosis of uterine carcinosarcoma (UC). MATERIALS AND METHODS: A retrospective review of three cancer registry databases in Turkey was conducted for identification of patients diagnosed with UC between January 1, 1996, and December 31, 2012. We collected clinicopathological data in order to evaluate factors important in disease- free survival (DFS) and overall survival (OS). RESULTS: A total of 66 patients with UC with a median age of 65.0 years were included in the analysis. The median survival time of all patients was 37.5 months and the 5-year OS rate was 59.1%. In early stage patients (I-II) who received adjuvant chemotherapy (CT) with radiation therapy (RT), the median DFS and OS was 44 months and 55 months, respectively, compared to 34.5 months and 36 months, respectively, in patients who received adjuvant RT or CT alone (hazard ratio [HR], 1.4; 95% confidence interval [CI], 0.7 to 3.1 for DFS; p=0.23 and HR, 2.2; 95% CI, 0.9 to 5.3 for OS; p=0.03). In advanced stage patients (III-IV), the median DFS and OS of patients receiving adjuvant RT with CT was 25 months and 38 months, respectively, compared to 23.5 months and 24.5 months, respectively, in patients receiving adjuvant RT or CT alone (HR, 3.1; 95% CI, 0.6 to 16.0 for DFS; p=0.03); (HR, 3.3; 95% CI, 0.7 to 15.0 for OS; p=0.01). In multivariate analysis, advanced International Federation of Gynecology and Obstetrics (FIGO) stage and suboptimal surgery showed significant association with poor OS. CONCLUSION: In patients with early or advanced stage UC, adjuvant CT with RT is associated with improved DFS and OS, as compared to CT or RT alone.

RESUMO

BACKGROUND: To evaluate and compare the efficacy of vaginal misoprostol and a rectal nonsteroidal anti-inflammatory drug (NSAID) on pain relief during Pipelle endometrial biopsies in a placebo-controlled randomized study. METHODS: One hundred and fifty-one women who had an indication for a Pipelle endometrial biopsy were randomized into three groups as follows: group 1, vaginal misoprostol; group 2, rectal NSAID, and group 3, control. After the procedure, the women were asked to record their pain severity on a visual analog scale. The secondary outcome of the study was patient acceptability, and vasovagal symptoms and analgesic requirements after the procedure were also recorded. RESULTS: There were no statistically significant differences in the demographic characteristics of the patients. The primary study outcome was the comparison of the median visual analog scale pain scores of groups 1 and 2 versus group 3 (controls); no statistically significant differences were found (p = 0.502). In addition, the patient acceptability (Likert scale), vasovagal symptoms and analgesic requirements after the procedure were similar among the groups (p = 0.204, 1 and 0.546, respectively). CONCLUSION: Our study did not demonstrate a reduction in pain relief during Pipelle endometrial biopsies for patients receiving vaginal misoprostol or a rectal NSAID when compared to patients receiving placebo treatment.

RESUMO

BACKGROUND: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. MATERIALS AND METHODS: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. RESULTS: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. CONCLUSIONS: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.

RESUMO

OBJECTIVES: We hypothesized that sonographically guided core biopsy is an effective method for the differential diagnosis of adnexal masses and evaluated patients who underwent core biopsies in our gynecologic oncology department. METHODS: We reviewed the medical records of 55 patients who underwent sonographically guided core biopsies in our gynecologic oncology department between 2010 and 2013. Patients with suspected ovarian malignancies who were unsuitable for optimal debulking surgery and patients at risk for higher morbidity and mortality because of a poor performance status, suspected nongynecologic tumors, and peritoneal tuberculosis were indicated for sonographically guided biopsy. RESULTS: The indications for sonographically guided core biopsy were candidacy for suboptimal cytoreduction (n = 32 [58.2%]), a poor performance status (n = 11 [20.0%]), and suspected nongynecologic tumors (n = 12 [21.8%]). Histopathologic evaluations revealed primary ovarian tumors in 36 patients (65.5%). Tuberculosis was found to be the second most common disease (n = 8 [14.5%]) among the patients who underwent core biopsies. In 2 patients (3.6%), histologic examination revealed metastatic colorectal cancer. CONCLUSIONS: Sonographically guided core biopsy may be preferred as a minimally invasive procedure for managing adnexal masses, particularly in patients with advanced ovarian cancer and high comorbidities who might benefit from neoadjuvant chemotherapy and in cases of suspected nongynecologic tumors, including pelvic tuberculosis.
