background : this study compared the efficacy of two commonly used fractionation schedules for palliative whole brain irradiation in patients with brain metastases, and assessed the association of the radiotherapy therapy oncology group (rtog) recursive partitioning analysis for brain metastases (rpa) to survival with each schedule. methods : patients with multiple (more than three) brain metas...
Cholangiocarcinoma (CCA) is a deadly disease arising from the malignant transformation of cholangiocytes. Enhancer of zeste homolog 2 (EZH2) is overexpressed in poorly differentiated CCA. Functional single nucleotide polymorphisms (SNPs) in this gene may affect the role of EZH2 in cholangiocarcinogenesis and chemoresistance. The aim of the current study was to evaluate the correlation between E...
the 5-year survival rate is a good prognostic indicator for patients with gastric cancer that is usually estimated based on kaplan-meier. in situations where censored observations are too many, this method produces biased estimations. this study aimed to compare estimations of kaplan-meier and weighted kaplan-meier as an alternative method to deal with the problem of heavy-censoring. data from ...
Intraoperative radiation therapy (IORT) is a multidisciplinary approach in which residual tumors or tumor beds are directly irradiated during a surgical procedure. To evaluate its efficacy, from 1985, we conducted a prospective study including non-metastatic gastric adenocarcinoma treated by surgery, IORT (15 Grays) and postoperative external beam radiotherapy (44 Grays). Up to 1993, 51 ca...
to compare the reproductive performance of the wild and cultured stocks of beluga, huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and larval growth and survival rates. the semen samples were sampled from 11 wild spawners and 12 cultured brooders. a half of each semen sample was allo...
