Research progress on factors affecting the sensitivity of breast cancer to radiotherapy: a narrative review.

Background And Objective: Radiation therapy (RT) is one of the important components of comprehensive treatment for breast cancer and has important value in improving the control rate of local areas, reducing the chance of recurrence and metastasis after breast cancer surgery, delaying disease progression, and improving the survival of breast cancer patients. The factors that affect the RT sensitivity of breast cancer are important. The above potential predictors of radiation efficacy can provide patients with a predictive method and therefore have significant value in clinical therapy.

Correlation between the CD4+CD25high regulatory T cells and the outcome of chemotherapy in advanced esophageal carcinoma.

Background/aims: In patients with esophageal carcinoma, local immune suppression and the expression of soluble immunosuppressive factors have been observed. We aimed to investigate the correlation between the level of CD4+CD25high regulatory T (Treg) cell and the outcome of chemotherapy in advanced esophageal carcinoma.

Methodology: Forty-eight cases of advanced esophageal carcinoma patients were enrolled from June 2006 to December 2008.

Fatal lactic acidosis and hypoglycemia in a patient with relapsed natural killer/T-cell lymphoma.

Presented here is the first reported case of natural killer (NK)/T-cell lymphoma associated with lactic acidosis (LA) and hypoglycemia. LA and hypoglycemia are rare complications of non-Hodgkin's lymphoma. A 28-year-old male patient with NK/T-cell lymphoma had a relapse after 14 mo of initial remission and was admitted to the hospital because of altered mental status.
