Clinical efficacy of preoperative vaginal intracavitary irradiation for Stage Ib2 and IIa cervical cancer.

Objective: The purpose of this study was to evaluate the clinical efficacy of preoperative vaginal intracavitary irradiation for Stage Ib2 and IIa cervical cancer.

Materials And Methods: From June 2008 to June 2014, data from 78 Stage Ib2 and IIa cervical cancer patients (age ≤75 years) with a diameter of local lesions >4 cm were collected in our hospital. Before treatment, all cases were confirmed by biopsy.

CXCL5 Plays a Promoting Role in Osteosarcoma Cell Migration and Invasion in Autocrine- and Paracrine-Dependent Manners.

CXCL5, a CXC-type chemokine, is an important attractant for granulocytic immune cells by binding to its receptor CXCR2. Recently, CXCL5/CXCR2 has been found to play an oncogenic role in many human cancers. However, the exact role of CXCL5 in osteosarcoma cell migration and invasion has not been revealed.

[Mechanistic study of radiosensitization by gemcitabine on human squamous carcinoma cell line of the cervix].

Objective: To investigate whether gemcitabine (dFdC) at the non-cytotoxic concentration enhances the effect of irradiation on human squamous carcinoma cells of the uterine cervix (HeLa) in vitro, and to evaluate the mechanism by which dFdC at the non-cytotoxic concentration [24 h 10% inhibiting concentration (IC(10))] is able to enhance radiation-induced cytotoxicity to HeLa in vitro.

Methods: The non-cytotoxic concentration (24 h IC(10)) of dFdC was determined by methyl thiazolyl tetrazolium (MTT). After exposure to the non-cytotoxic concentration (0.
