The International Association for the Study of Lung Cancer (IASLC) has presented the details of the IASLC/International Union Against Cancer (UICC)/American Joint Committee on Cancer (AJCC) Revised Staging Classification for Lung Cancer. The IASLC is the largest world-wide professional organization solely dedicated to reduce the worldwide burden of lung cancer. The IASLC recognizes that the staging classification will be most valuable and accurate if it is based on the evaluation of outcomes of large numbers of cases carefully collected and analyzed in an extensive worldwide database. The analyses of the T, N and M descriptors as well as the stage groupings were performed in 67,725 non-small cell lung cancer (NSCLC)patients. Survival was the primary outcome, measured from the date of diagnosis or date of protocol registration for clinical staging, or the date of surgery for pathologic staging. The remarkable efforts of the IASLC Staging Committee have resulted in an evidence-based, validated and robust revision of the international staging system for NSCLC. This landmark contribution will improve our care of patients and lays a strong foundation for future refinements based on an expanding knowledge of lung cancer behavior and biology. This review outlines the changes in the tumor, node, metastasis (TNM) descriptors and stage groupings anticipated in the official new stage classification system for NSCLC.

Objective: To investigate the expression of Cyclin G mRNA in leukemia patients and its clinical significance. Methods: RT-PCR was used to analyze the expression of Cyclin G mRNA in the mononuclear cells of 129 leukemia patients and 10 healthy controls. Results: (1) The expression of Cyclin G in acute leukemia (AL) and chronic leukemia (CL) patients was significantly higher than that in healthy controls (both P 50?109/L in AL and AML groups were significantly higher than those with WBC ≤ 50?109/L. (4) Fifty-three of the newly diagnosed cases were Cyclin G positive. The remission rate of patients with high Cyclin G expression(51.7%)was significantly lower than that with low Cyclin G expression(79.1%)(P

With the profound study of PDT mechanism and the new type of photosensitizers,the application of PDT to hematopoietic diseases has become a new domain.The relapsing/refractory aggressive lymphoma is one of the tough problems which are still unsolved in hematopoietic domain. Now,the experimental and clinical research on application of PDT in lymphomas has become the hot topic for the domestic and world scholars.

Surgical resection (usually lobectomy) is considered the treatment option for individuals with stage Ⅰ and Ⅱ non-small cell lung cancer. The surgical treatment of stage Ⅰ and Ⅱ non-small cell lung cancer (NSCLC) continues to evolve in the areas of intraoperative lymph node staging (specifically the issue of lymph node dissection vs sampling), the role of sublobular resections instead of lobectomy for treatment of smaller tumors (especially peripheral carcinoma ≤2 cm in diameter), and the use of video-assisted techniques to perform anatomic lobectomy. Video-assisted thoracic surgery (VATS) lobectomy provides a minimally invasive approach for the management of early-stage lung cancer. Questions about the safety of VATS lobectomy and its adequacy as a cancer operation compared with open thoraeotomy have hindered its universal acceptance among thoracic surgeons. Evidence suggests that VATS lobectomy can be safely performed and is an adequate cancer operation for early-stage NSCLC. Recently, robots have been introduced into surgical procedures in an attempt to facilitate surgical performance. However, adequately powered well-balanced studies comparing VATS with open thoracotomy for lobectomy are lacking in the literature.

Objective To compare the results of surgical treatment of cardiac carcinoma through left thoracic approach and abdominal approach.Methods After finished cardiac carcinoma resection and gastroesophagus anastomosis in thorax through left thoracic approach,standard D2 regional lymph nodes dissection or/and combined pancreas and spleen resection were performed immediately through abdominal approach in 19 patients.Two surgical specimens were examined individually.Results 122 lymph nodes were founded in the abdominal surgical specimens,in which 23 were metastasis lymph nodes founded in 7 patients (7/19,37 %).Conclusion Left thoracotomy alone can no achieve complete resection for advanced gastric cardiac carcinoma.It should be treated through the combined abdominal and thoracic approach.

Objective:To investigate the effect of SU11248 proliferation and apoptosis of multiple myeloma cell line U266 in vitro and analyze its mechanisms.Methods:Effect of SU11248 on proliferation of U266 cells was detected by MTT assay.The ability of SU11248 to induce apoptosis of U266 cells was examined by cell cycle analysis,TUNEL and DNA fragmentation.Expression of c-myc,hTERT,Bcl-2 and Bax mRNA in U266 cells was assessed by RT-PCR analysis.Results:The proliferation of U266 cells was inhibited by SU11248 in dose-and time-dependent manners (P

Objective Lung cancer has been the most common cause of cancer death worldwide.More than three quarters is diagnosed at advanced stage.Nearly one half has distant metastases outside the chest cavity.It has been recognized that oligometastatic state exists in natural history of malignant tumors,which has significantly better prognosis than those with polymetastases.The eighth edition of TNM staging system defined NSCLC with a single metastasis as a new separated stage(M1 b).Long-term survival of oligometastatic NSCLC patients treated with local control methods has been reported in literatures.But whether surgical resection of liver metastasis has benefit or not remains unknown.We performed a systematic review of surgical therapy for NSCLC with limited liver metastases.

Objective:To study the expression levels of nuclear factor kappa B, Bcl-2 associated K and TNF-αproteins to discuss the effects of NF-κB and Bak proteins in the pathogenesis of UC.Methods:Eighty clean grade of adult Sprague-Dawley( SD) rats were used,male and female in half and then rando mly selected sixty as the model group,another twenty as the control group.SD rats model were manufactured by a compound method:Trinitrobenzene sulfonic acid ( TNBS )+ethanol.We observed and assessed colonic mucosa by the general morphology and histological changes.To applicated immunohistochemistry and RT-PCR methods to detected the protein and mRNA expression levels of NF-κB,Bak and TNF-αin the model groups and the control group and to analysed their relationships.Results:The successful rate of making model was 97%.The number of inflammatory cells in the model groups more than the control(P<0.01).Group immunohistochemical and RT-PCR,NF-κB and TNF-αproteins and mRNA in UC colon epithelium cells and inflammatory cells were higher than the control(P<0.01).Bak protein in inflammatory cells were lower than the control(P<0.01),but there was no statistical significance in epithelial cells(P>0.05).The expression levels of NF-κB,TNF-αincreased as the histological grade increased(P<0.05),however,the expression level of Bak decreased(P<0.05).NF-κB in colonic mucosa of rats with UC had a significantly positive correlation with that of TNF-α(r=0.892,P<0.01),and negatively correlated with that of Bak(r=-0.793,P<0.01).Conclusion:The levels of NF-κB and Bak may be related to the occurrence and development of UC.

Objective Diffusion tensor imaging(DTI)was used to explore the characteristics of white matter (WM)microstruc-ture lesion in patients with temporal lobe epilepsy(TLE)and hippocampal sclerosis(HS).Then we investigated the influence of the age of epilepsy onset and the course on WM changes.Methods DTI data were obtained in 30 TLE patients with HS and 23 age and sex-matched healthy controls.Thirteen patients had left HS (LHS)and seventeen had right HS (RHS).Between-group compari-sons of fractional anisotropy (FA)were carried out by using track-based spatial statistics (TBSS).In addition,FA in regions of in-terest (ROI)where white matter lesions had statistically significant difference was correlated with the age of onset and the course. Results Subjects in the LHS group,as compared to healthy controls,demonstrated these clusters of reduced FA:bilateral corona radiata,the left genu of corpus callosum,the right body and splenium of corpus callosum,the right posterior thalamic radiation,ex-ternal capsule and superior longitudinal fasciculus.White the subjects in the RHS group,the clusters of reduced FA are involving bi-lateral corpus callosum,corona radiata,posterior thalamic radiation,cingulum,superior longitudinal fasciculus,and the right ante-rior limb of internal capsule,the right retrolenticular part of internal capsule and external capsule.In LHS group,the FA of the left genu of corpus callosum was negatively correlated with the course,and the FA of the right anterior corona radiata was positively cor-related with the age of onset.In RHS group,the FA of the bilateral superior corona radiata was positively correlated with the course.Conclusion DTI detects extensive changes in TLE with HS that are not confined to temporal lobe.The age of epilepsy onset in LHS was correlated with the changes of anterior corona radiata,while the course and the WM change were not definitely linked to each other.
