ObjectiveTo evaluate the relationship between pelvic/para-aortic sentinel lymph node status and two different injection sites of 99m-technetium (99mTc)-labeled phytate in patients with endometrial cancer.MethodsThis was a randomized controlled trial involving 81 patients with endometrial cancer. In the cervical group (n=40), injections of 99mTc were performed at the 3 and 9 o’clock positions of the uterine cervix. In the endometrial group (n=41), 99mTc was injected into the fundal endometrium using a transcervical catheter. Sentinel lymph nodes were detected through pre-operative lymphoscintigraphy and intra-operatively using a handheld gamma probe. All patients underwent complete pelvic and para-aortic lymphadenectomy procedures. Pathologic ultra-staging was performed with immunostaining for cytokeratin in sentinel lymph nodes after routine hematoxylin and eosin histological examinations. The primary endpoint was the estimation of detection rates, sensitivity, false-negative rates, negative predictive value, and analysis of the distribution of pelvic and para-aortic sentinel lymph nodes.ResultsThe rate of detection of at least one sentinel lymph node, sensitivity, and the negative predictive value was 80%, 66.6%, 96.6% for the cervical group and 85%, 66.6%, 96.9% for the endometrial group, respectively. False-negative sentinel lymph nodes were detected in one patient from each group . There was no significant difference between the groups in terms of total sentinel lymph node count, sentinel pelvic lymph node count, and pelvic bilaterality, but the para-aortic sentinel lymph node count was significantly higher in the endometrial group (p<0.001). Ultra-staging examination of the pelvic sentinel lymph nodes revealed isolated tumor cells in one patient from each group.ConclusionTranscervical endometrial tracer injection in endometrial cancer revealed similar pelvic but significantly higher para-aortic sentinel lymph node detection.
Objective. Tumor budding defined as a tumor cell nest away from the main tumor, has been found to be associated with prognostic parameters in many cancer types. We aimed to investigate the relationship between tumor budding and clinicopathological parameters in endometrioid endometrial carcinomas, as well as its prognostic importance. Materials and Methods. One hundred four patients who underwent surgical resection with diagnosis of endometrioid endometrial carcinomas between June 2011 and May 2020 were included. The area where tumor budding was the most prominent was determined, and tumor budding was counted from hematoxylin and eosin-stained section at one high power field (X 200). By performing ROC analysis, the cut off value was obtained in order to divide the patients into low and high tumor budding groups. Results. The cut off value was determined as 1/0.95 mm2 according to the ROC analysis. Tumor budding was observed in 24 (23%) patients. Tumor budding significantly associated with poor overall survival ( P < .001), distant metastasis ( P = .001), presence of angiolymphatic invasion ( P < .001), lymph node metastasis ( P = .024), cervical invasion ( P < .001), high FIGO grade ( P < .001), large tumor size ( P = .004). In multivarate analysis, tumor budding and age were found to be an independent risk factor for overall survival ( P = .003, P = .014 respectively). Conclusion. Tumor budding is a significant morphological parameter independent of other prognostic parameters in endometrioid endometrial carcinomas. Standardizing the assesment and scoring of tumor budding, as well as including this entity in routine pathology reports could light the way for ideas in the risk analysis of patients.
Late diagnosis and treatment of ovarian ischemia can lead to worsening of ischemia, irreversible damage to ovarian functions and infertility. In this process, there is no approved medical treatment that can reduce the negative effects of ischemia and contribute positively to ovarian functions during reperfusion after detorsion. Rats were randomly assigned into one of six groups of eight animals each. The groups were designed as follows: The control group, The ischemia(I) group, The Ischemia + Trimetazidine (I + TMZ) (20 mg/kg) group, and The ischemia-reperfusion group (I/R). The Ischemia-Reperfusion + Trimetazidine (I/R + TMZ) (20 mg/kg) group, and The Sham + Trimetazidine (Sham + TMZ) (20 mg/kg) group. In this study performed thiobarbituric acid reactive substances (TBARS), total thiol (-SH), interleukin 1 beta (IL-1β), interleukin 6 (IL-6), toll-like receptor 4 (TLR4), and nuclear factor-kappa B(NF-κβ). Increased oxidative stress and inflammation were as a result of ovarian I and I/R application. Trimetazidine (TMZ), was sufficient to reduce the oxidative stress and inflammation. TLR4 and NF-κβ, which were upregulated by oxidative stress and inflammation, were regressed by TMZ. TMZ should be considered as a potential therapeutic agent in addition to surgery in the clinical treatment of ovarian torsion.
