CircATXN7 regulates the proliferation and invasion of esophageal cancer cells through miR-4319/NLRC5.

Background: This study aimed to explore the molecular mechanism through which circular RNA of ataxin 7 (circATXN7) regulates the proliferation and invasion of esophageal cancer (EC) cells via microRNA (miR)-4319/NLR family CARD domain containing 5 (NLRC5).

Methods: The localization of circATXN7 in EC cells was determined by RNA fluorescent in situ hybridization (RNA-FISH). The mRNA levels of circATXN7, miR-4319, and NLRC5 were quantified by reverse transcription-polymerase chain reactions.

Effects of sintilimab plus chemotherapy as first-line treatment on health-related quality of life in patients with advanced esophageal squamous cell carcinoma: results from the randomized phase 3 ORIENT-15 study.

Background: In ORIENT-15 study, sintilimab plus chemotherapy demonstrated significant improvement on overall survival (OS) versus placebo plus chemotherapy in first-line treatment of advanced esophageal squamous cell carcinoma (ESCC). Here, we report effect of sintilimab plus chemotherapy on health-related quality of life (HRQoL) in patients with advanced ESCC.

Methods: From December 14, 2018 to August 28, 2022, HRQoL was evaluated in all randomized patients using European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 items (QLQ-C30), EORTC Quality of Life Questionnaire Oesophageal Cancer Module 18 items (QLQ-OES18), and visual analogue scale (VAS) of the EuroQol five-dimensional five-level questionnaire (EQ-5D-5L).

Expression of CircATXN7 in esophageal cancer tissues and its effect on cell proliferation and invasion.

Background: The goal of the current research was to investigate circATXN7 expression in esophageal cancer (EC) and its impact on the proliferation, migration, and invasion of EC cells.

Methods: Determination of circATXN7 expression in esophageal cancer tissues and adjacent tissueswas carried out using quantitative reverse transcription polymerase chain reaction (qRT-PCR), and we further analyzed the correlation between patients' clinical characteristics and circATXN7 expression. EC cell lines (EC-9706, Eca-109, TE-1, KYSE-30, and KYSE-150) and normal esophageal cell line (HET-1A) were cultured, and circATXN7 expression was detected by qRT-PCR.

Sintilimab versus placebo in combination with chemotherapy as first line treatment for locally advanced or metastatic oesophageal squamous cell carcinoma (ORIENT-15): multicentre, randomised, double blind, phase 3 trial.

Objective: To evaluate sintilimab versus placebo in combination with chemotherapy (cisplatin plus paclitaxel or cisplatin plus 5-fluorouracil) as first line treatment of unresectable locally advanced, recurrent, or metastatic oesophageal squamous cell carcinoma.

Design: Multicentre, randomised, double blind, phase 3 trial.

Setting: 66 sites in China and 13 sites outside of China between 14 December 2018 and 9 April 2021.

Knockdown of lncRNA TUC338 inhibits esophageal cancer cells migration and invasion.

Background: Long non-coding RNAs (lncRNAs) are firmly identified with the event and improvement of tumors. Therefore, elucidating the functions and mechanisms of related lncRNAs is significant for understanding the occurrence and advancement of tumors. The recently discovered lncRNA TUC338 has been shown to play the role of an oncogene in an assortment of tumors.

Axis-Mediated Metabolism Alternations of Inflammation-Related Glycolysis Involve with Colorectal Carcinogenesis.

Chronic inflammation is a major driving factor for the development of colitis-associated cancer (CAC). It is extensively acknowledged that patients who have long-standing inflammation bowel disease are at high risk for developing CAC. However, the metabolic alteration by which chronic intestinal inflammation promotes colorectal cancer is unclear.

Partial response to chemotherapy in a patient with retroperitoneal inflammatory myofibroblastic tumor.

Retroperitoneal inflammatory myofibroblastic tumor (IMT) is a rare lesion of unknown etiology. The management of IMT may be challenging due to its intermediate malignant potential, the possibility of local recurrence after surgical resection and its unique anatomic location, which makes radical resection impossible due to its proximity to vital structures. Thus, treatment for recurrence and metastasis mainly relies on chemotherapy.

Polymorphisms of p53 and MDM2 genes are associated with severe toxicities in patients with non-small cell lung cancer.

Adverse events in platinum-based chemotherapy for patients with advanced non-small cell lung cancer (NSCLC) are major challenges. In this study, we investigated the role of the p53 and MDM2 genes in predicting adverse events in NSCLC patients treated with platinum-based chemotherapy. Specifically, we examined the p53 p.

Multicenter clinical study for evaluation of efficacy and safety of transdermal fentanyl matrix patch in treatment of moderate to severe cancer pain in 474 chinese cancer patients.

Objective: Although a new matrix formulation fentanyl has been used throughout the world for cancer pain management, few data about its efficacy and clinical outcomes associated with its use in Chinese patients have been obtained. This study aimed to assess the efficacy and safety of the new system in Chinese patients with moderate to severe cancer pain.

Methods: A total of 474 patients with moderate to severe cancer pain were enrolled in this study and were treated with the new transdermal fentanyl matrix patch (TDF) up to 2 weeks.

Lung cancer risk associated with Thr495Pro polymorphism of GHR in Chinese population.

The incidence of lung cancer has been increasing over recent decades. Previous studies showed that polymorphisms of the genes involved in carcinogen-detoxication, DNA repair and cell cycle control comprise risk factors for lung cancer. Recent observations revealed that the growth hormone receptor (GHR) might play important roles in carcinogenesis and Rudd et al.

The expression and location of midkine in gastric carcinomas of Chinese patients.

Midkine (MK), a heparin-binding growth factor, can regulate cell growth, survival and differentiation. MK is expressed at high levels in a variety of human carcinomas. Recently, the urine and serum MK concentration was analyzed in gastric cancer patient.

[Polymorphism of porcine myostatin gene].

Myostatin(MSTN) gene is expressed specifically in developing and mature skeletal muscle, and the expression products of MSTN gene inhibits muscle growth and differentiation. The polymorphism of the porcine MSTN gene was researched by PCR-SSCP. The SSCP was found in the MSTN gene exon 2 and exon 3.
