However, some patients may not be able to receive this regimen.

Whole brain radiotherapy induces cognitive dysfunction in mice: key role of gut microbiota.

Rationale: Approximately 20-40% of patients with cancer will experience brain metastasis (BM), which has a great impact on the quality of life and survival rates of patients. Whole brain radiotherapy (WBRT) is an effective method for the treatment of BM. However, it cannot be ignored that WBRT might induce a series of neuropsychiatric side effects, including cognitive dysfunction (CD).

Impact of genetic variant of HIPK2 on the risk of severe radiation pneumonitis in lung cancer patients treated with radiation therapy.

Background: Homeodomain-interacting protein kinase 2 (HIPK2) has increasingly drawn attention as recent researches demonstrated its unique role in the regulation of multiple fundamental processes such as apoptosis, proliferation and DNA damage repair. Most importantly, HIPK2 was shown to play regulatory role in inflammation and influence the phenotype and activity of fibroblasts. In this study, we aimed to evaluate the impact of HIPK2 gene variant on risk of radiation pneumonitis for patients with pulmonary malignancies.

Validation study of the association between genetic variant of IL4 and severe radiation pneumonitis in lung cancer patients treated with radiation therapy.

Background And Purpose: Recent researches demonstrated that single nucleotide polymorphisms (SNPs) of genes involving inflammation, DNA repair, etc. were associated with risk of radiation pneumonitis (RP). However, these studies were single-centered, from single ethnic origin, without validation from independent cohort studies from other populations.

The Chinese Society of Clinical Oncology (CSCO): clinical guidelines for the diagnosis and treatment of gastric cancer.

China is one of the countries with the highest incidence of gastric cancer. There are differences in epidemiological characteristics, clinicopathological features, tumor biological characteristics, treatment patterns, and drug selection between gastric cancer patients from the Eastern and Western countries. Non-Chinese guidelines cannot specifically reflect the diagnosis and treatment characteristics for the Chinese gastric cancer patients.

High infiltration of CD68-tumor associated macrophages, predict poor prognosis in Kazakh esophageal cancer patients.

Tumor-associated macrophages (TAMs), the most important immune cells in tumor microenvironment, were reported to play a key role in cancer progression, but the correlation of TAMs and Kazakh esophageal squamous cell carcinoma (ESCC) was still not clear, so we sought to identify the function of TAMs in Kazakh ESCC clinicopathological and prognostic evaluation. CD68 as the TAMs marker, and immunohistochemistry (IHC) was used to quantify IHC staining was also used to evaluate the expression of MMP-9 in Kazakh ESCCs. The density of CD68-TAMs in ESCCs tumor nest and stromal, were significantly higher than those of CANs (P<0.

Regulatory Role of miR-203 in Occurrence and Progression of Kazakh Esophageal squamous cell carcinoma.

Esophageal carcinoma is one of the most common malignant tumors and the Kazakh national minority (ethnic) in Xinjiang (northwest of China) has been reported to be one of the highest incidence of Esophageal squamous cell carcinoma (ESCC) in the world. MicroRNA-203 (miR-203) was described as a tumor-suppressive miRNA in several cancers, but little study about the role of miR-203 in Kazakh ESCC. Therefore, we aimed to investigate the role of miR-203 in the occurrence and progression of Kazakh ESCC.

Expert consensus on maintenance treatment for metastatic colorectal cancer in China.

The impact of maintenance therapy on progression-free survival and overall survival as well as quality of life of Chinese patients with metastatic colorectal cancer has long been under discussion. Recently, some phase III clinical trials have revealed that maintenance therapy can significantly prolong the progression-free survival while maintain an acceptable safety profile. Based on this evidence and common treatment practice in China, we now generated one Expert Consensus on Maintenance Treatment for Metastatic Colorectal Cancer in China to further specify the necessity of maintenance therapy, suitable candidates for such treatment, and appropriate regimens.
