MiR-30a-5p inhibits cell behaviors in esophageal cancer via modulating CBX2.

Background: This investigation studied the impacts of the miR-30a-5p/CBX2 axis on esophageal cancer (EC).

Methods: Research objects were ascertained using The Cancer Genome Atlas database. Followed by qRT-PCR, western blot, dual-luciferase reporter, MTT, Transwell, and wound healing approaches, we tested gene expression and varying cell behaviors RESULTS: Conspicuously miR-30 family members (miR-30a-5p, miR-30b-5p, miR-30c-5p, miR-30d-5p, miR-30e-5p) downregulation and CBX2 upregulation were discovered in EC cells.

miR-3942-3p Increases the radiosensitivity of nasopharyngeal carcinoma through negatively regulating BARD1.

Nasopharyngeal carcinoma (NPC) has high incidence in China and East and Southeast Asia. The study was performed to investigate the effect of microRNA3942-3p (miR-3942-3p) on the radiosensitivity of NPC. Compared with non-cancer tissue, NPC had significantly lower miR-3942-3p expression.

Endostar, an Antiangiogenesis Inhibitor, Combined With Chemoradiotherapy for Locally Advanced Cervical Cancer.

This phase II randomized clinical trial aimed to assess the efficacy and toxicity of Endostar, an antiangiogenesis inhibitor, combined with concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC). Patients with LACC were randomly assigned to either CCRT plus Endostar (CCRT+E arm) or CCRT alone (CCRT arm). All patients received pelvic intensity-modulated radiation therapy (IMRT) and brachytherapy.

Hyperprogression After Immunotherapy for Primary Small Cell Neuroendocrine Carcinoma of the Ureter: A Case Report.

Background: Primary small cell neuroendocrine carcinoma (SCNEC) in the ureter is extremely rare and has been sporadically reported in case reports. Its incidence, diagnosis, treatment, and outcomes have not yet been thoroughly understood. Here we present a patient with advanced SCNEC in the ureter who was treated by multimodal strategies.

Long-Term Results of Concurrent Chemoradiotherapy Combined with Anti-EGFR Monoclonal Antibody Prior to Surgery in Locally Advanced Cervical Cancer: A Single-Institute Prospective Study.

Purpose: We aimed to evaluate the long-term survival outcomes of concurrent chemoradiotherapy (CCRT) combined with nimotuzumab followed by surgery in patients with locally advanced cervical cancer (LACC).

Patients And Methods: Patients received whole pelvic intensity-modulated radiation therapy (IMRT) and concomitantly with weekly cisplatin (40 mg/m) or nedaplatin (30 mg/m) and weekly nimotuzumab (200 mg). After assessment of the treatment response, patients then underwent radical surgery.

A prospective study on neoadjuvant chemoradiotherapy plus anti-EGFR monoclonal antibody followed by surgery for locally advanced cervical cancer.

Background: To investigate the efficacy and safety of neoadjuvant chemoradiotherapy plus anti-epidermal growth factor receptor monoclonal antibody followed by surgery for locally advanced cervical cancer (LACC).

Patients And Methods: Patients with histologically proven LACC were enrolled into this prospective study. All patients received intensity-modulated radiation therapy with conventional fractionation.

Dosimetric study of a respiratory gating technique based on four-dimensional computed tomography in non-small-cell lung cancer.

This study sought to compare the differences in target volumes and dose distributions to the targets and organs at risk (OARs) between a four-dimensional computed tomography (4DCT)-based respiratory-gated intensity-modulated radiation therapy (IMRT) plan (PlanEOE) and a three-dimensional CT (3DCT)-based IMRT plan (Plan3D) in patients with non-small-cell lung cancer (NSCLC). For 17 patients with Stages I-III NSCLC, both 4DCT data and conventional 3DCT data were obtained. The Plan3D and PlanEOE were designed based on 3DCT data and 4DCT data, respectively.

Expression of DNA-PKcs and BRCA1 as prognostic indicators in nasopharyngeal carcinoma following intensity-modulated radiation therapy.

The mechanisms of radiation-induced effects in cancer mainly involve double-strand breaks (DSBs) which are important in maintaining the stability of genes. The DNA repair genes breast cancer 1 (BRCA1) and DNA-dependent protein kinase catalytic subunit (DNA-PKcs) are capable of maintaining genetic stability through two distinct and complementary repair mechanisms for DNA DSBs, known as repair-homologous recombination (HR) and non-homologous end joining (NHEJ). DNA-PKcs is a member of the phosphatidylinositol 3-kinase (PI3K) family.

Interfractional and intrafractional errors assessed by daily cone-beam computed tomography in nasopharyngeal carcinoma treated with intensity-modulated radiation therapy: a prospective study.

This prospective study was to assess interfractional and intrafractional errors and to estimate appropriate margins for planning target volume (PTV) by using daily cone-beam computed tomography (CBCT) guidance in nasopharyngeal carcinoma (NPC). Daily pretreatment and post-treatment CBCT scans were acquired separately after initial patient setup and after the completion of each treatment fraction in 10 patients treated with IMRT. Online corrections were made before treatment if any translational setup error was found.

Feasibility and efficacy study of weekly cisplatin with concurrent intensity-modulated radiation therapy for nasopharyngeal carcinoma: preliminary results.

The aim of this study was to assess the feasibility and efficacy of a weekly cisplatin 40 mg/m(2) regimen in patients with nasopharyngeal carcinoma treated concurrently with definitive intensity-modulated radiation therapy (IMRT). The primary endpoints were treatment compliance and acute toxicities. Twenty-two patients with newly diagnosed NPC were recruited in this phase II trial.

Intrathoracic Endotracheal Metastasis from Nasopharyngeal Carcinoma: A First Case Report and Review of the Literature.

Intrathoracic endotracheal metastasis from a very distant site is extremely rare. We report the first case of such a disease in a 68-year-old man with nasopharyngeal carcinoma who presented with a cough and hemoptysis 34 months after finishing radiotherapy. Prior to tracheal metastasis, he developed a solitary metastasis in the lung and underwent chemotherapy followed by radiotherapy.

Concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma: a treatment paradigm also applicable to patients in Southeast Asia.

The majority of nasopharyngeal carcinoma (NPC) patients present at locally advanced stage. The poor prognosis has led to increasing interests in exploring the use of chemotherapy (CT). Intergroup-0099 trial was the first randomized trial comparing concurrent chemoradiotherapy (CCRT) with radiotherapy (RT) alone.
