Factors of oral infection in elderly patients with head and neck radiotherapy for malignant lymphoma / 中华老年医学杂志

Objective To investigate the factors relating to oral infection in elderly patients treated with head and neck radiotherapy for malignant lymphoma and to provide the clinical basis for the prevention and treatment of oral infections.Methods A total of 97 patients treated with head and neck radiotherapy for malignant lymphoma from March 2007 to March 2012 were enrolled.The factors relating to oral infection after head and neck radiation therapy were analyzed.Results Totally 25 patients (25.77％,25/97) had oral infections.The single-factor analysis showed that education degree,occupation,cancer staging,oral self-cleaning,oral environment,chemotherapy were the important factors relating to oral infection (x2 =8.634,6.863,9.237,11.870,7.563,8.012,P＜0.01).The incidence of oral infection had no significant differences between male and female patients.Conclusions There are many factors relating to oral infection in elderly patients treated with head and neck radiotherapy for malignant lymphoma,and poor oral self-cleaning,history of gum disease and chemotherapy are the important related factors.

Research progresses on K-RAS mutation of non-small cell lung cancer / 基础医学与临床

Mutated K-RAS is found in 15%～30% NSCLC patients, the mutations of K-RAS and EGFR are mutually exclusive,K-RAS mutations have poor sensitivity to EGFR-TKIs. The response of C-225 is not restricted to mutated K-RAS, NSCLC patients with K-RAS mutations are associated with unfavorable prognosis. A number of different approaches such as Ftase inhibitors, RAF inhibitors, MEK inhibitors aimed at abrogating K-RAS activity to improve clinical response have been explored in clinical trials.

A Randomized and Controlled Study of rhGM-CSF on Leucopenia Induced by Chemotherapy on Cancer Patients / 中国肿瘤生物治疗杂志

Objective: To evaluate the efficacy and tolerability of rhGM-CSF in prevention of neutropenia caused by chemothera- py of cancer patients. Methods: A muticenter, randomized,match and crossover clinical study was conducted. 64 enrolled patients were randomized into AB and BA groups and each patient received two cycles of combination chemotherapy.Results:59 patients were evaluted for clinical efficacy.rhGM-CSF significantly increased the number of WBC and ANC at the stage of nadir. The period when the patients, rhGM-CSF also resulted in a hastening recovery from leucopenia and neutropenia.Conclusion: The administraton of rhTM-CSF ensures the implement of sheduled combination chemotherapy. The main side effects such as fever, osteomyalgia,skin rash were generally tolerable.
