Objective To investigate the prognostic value of lymph node status evaluated by computed tomography (CT) in cervical carcinoma treated with radical chemoradiation therapy.Methods 209 patients with FIGO stage Ⅰ B-ⅣA uterine cervical carcinoma treated with radical chemo radiation therapy were enrolled.Lymph node status was evaluated based on site,number and size respectively by CT.Kaplan-Meier method was used to analyze the impact of lymph node status as well as other pathoclinical factors on overall survival (OS).Cox regression model was used to explore the relationship between independent prognostic factors and OS.Results Lymph node metastasis rates for stage Ⅰ B,Ⅱ,Ⅲ and ⅣA patients were 16.7 ％ (1/6),48.2 ％ (68/141),57.4 ％ (31/54) and 87.5 ％ (7/8),respectively.Variate analysis showed that FIGO stage,anemia before treatment,para-aortic lymph node metastasis,and the number (≥3) and size (maximum diameter ≥ 2.0 cm) of CT positive lymph node were significant unfavorable prognostic factors for OS (P ＜ 0.05).FIGO stage,the number of lymph nodes metastasis,pathologic diagnosis and treatment regimen were identified to be independent prognostic factors in multivariate analysis.Conclusion Under current therapeutic strategy of concomitant chemoradiotherapy,lymph node metastatic status evaluated by pretreatment CT is still a significant and independent prognostic factor for cervical cancer.

Chronic low back pain is a common worldwide high disabling physical and mental problem. The mindfulness based stress reduction (MBSR), a psychotherapy based on mindfulness, is widely recommended for chronic low back pain as a non-drug therapy. This article reviews the basic concepts, training methods of MBSR and the effects related to the improvement of pain related physiological and reactive behavior in patients with chronic low back pain, and analyses the problems that exist in the process of implementation in order to provide a basis for future clinical application.
