Carcinosarcomas have similar clinical characteristics and behaviour with grade 3 endometrioid or aggressive variants of uterine adenocarcinoma. All
studies have demonstrated that the FIGO stage of disease is the most important prognostic factor, followed by the depth of myometrial invasion, extra-uterine spread and positive peritoneal cytology. Moreover, lymph node involvement will be found in 14-38% of patients undergoing lymphadenectomy. This figure is similar to the one reported for endometrial carcinoma. Therefore, lymphadenectomy is mandatory for staging purposes. Regarding its impact on survival, the majority of studies www.selleckchem.com/products/gm6001.html confirm a significant survival benefit. The possible mechanisms for the improvement of survival from lymphadenectomy include removal of micro-metastatic foci, reduction of recurrence risk (removal of “”target
tissue”") and mechanical circumvallate of the disease. Given that 5-38% of the patients will experience local recurrence and 30-83% distant metastases, lymphadenectomy reduces the risk of the first and identifies patients in advanced stage that may benefit from adjuvant chemotherapy, aiming to reduce the second and ultimately improve overall survival.
Our review data fully justifies the rationale of lymphadenectomy, which beyond staging information
seems to offer selleckchem a measurable survival benefit.”
“In this study, melt-crystallization behaviors of poly(butylene terephthalate) (PBT) composites including different types of inorganic fillers were investigated. Composite samples having 5 wt % of fillers were prepared by melt processing in a twin screw extruder using commercial grades of calcite (CA), halloysite (HL), and organo-montmorillonite (OM) as filler. Depending on the filler type and geometry, crystallization kinetics of the samples was studied by differential scanning calorimetry (DSC) methods. Effect of filler type on the nonisothermal melt-crystallization kinetics of the PBT was analyzed with various kinetic models, namely, the Ozawa, Avrami modified by Jeziorny and Liu-Mo. Crystallization activation energies of the samples were also determined by the Kissinger, Takhor, and Augis-Bennett models. From the kinetics study, it was found that the melt-crystallization rates of the samples including CA and HL-nanotube were higher than PBT at a given cooling rate. On the other hand, it was also found that organo-montmorillonite reduced the melt-crystallization rate of PBT. It can be concluded that organic ammonium groups in the OM decelerate the crystallization rate of PBT chains possibly due to affecting the chain diffusion through growing crystal face and folding.
