The Sino-French 2012 Conference in Thoracic Oncology: an international academic platform for in-depth exchange on comprehensive research / 癌症

The Sino-French 2012 Conference in Thoracic Oncology, held November 17-18, 2012, was hosted by the Department of Thoracic Surgery at Sun Yat-sen University Cancer Center and organized in collaboration with two prestigious French hospitals: Institute Gustave Roussy and Marie Lannelongue Hospital. The conference was established by leading experts from China and France to serve as an international academic platform for sharing novel findings in basic research and valuable clinical practice experiences. Hot topics including innovation in surgical techniques, diagnosis and staging of early-stage lung cancer, minimally invasive surgery, multidisciplinary treatment of lung cancer, and progress in radiotherapy for lung cancer were explored. Highlights of the conference presentations are summarized in this report.

Effect of different ways of insulin infusion in parenteral nutrition patients on activation and concentration of insulin and blood glucose control:a prospective randomized comparison study / 中华外科杂志

<p><b>OBJECTIVE</b>To compare activation and concentration of insulin, and blood glucose control in patients between insulin added into "all in one" bags and syringes at parenteral nutrition (PN).</p><p><b>METHODS</b>From April 2006 to August 2006, 20 consecutive patients after gastrointestinal operations were recruited and randomized to instillation group and pump group. In instillation group, the insulin was directly added into PN and transfused. In pump group, the insulin was added into syringes and transfused by infusion pump. Activation and concentration of insulin, and blood glucose in patients were measured at beginning infusion, infused 1000 ml, infused 2000 ml, and remained 100 ml daily for the first 3 days after operation.</p><p><b>RESULTS</b>There was a tendency of decrease for the activation and concentration of insulin in both groups with the time. There was no significant difference of activation of insulin between the two groups (P = 0.347). There were no significant differences of blood glucoses between the two groups, and between the four time points in each groups (P > 0.05). There were no complications association with blood glucoses in the two groups.</p><p><b>CONCLUSIONS</b>Both of activation and concentration of insulin at PN decreased gradually and slightly with the time no matter the ways of insulin infusion. Activation of insulin and blood glucoses in patients are no significant differences between the two groups. Insulin can be safely added into "all in one" bags at PN.</p>

Injuries after lobectomy: a prospective randomized comparison of video-assisted thoracoscopic surgery and mini-thoracotomy / 中华外科杂志

<p><b>OBJECTIVE</b>To compare the differences of injuries and recovery between video-assisted thoracoscopic surgery (VATS) and mini-thoracotomy (MT) in patients with clinical early stage non-small cell lung cancer (NSCLC) after lobectomy.</p><p><b>METHODS</b>From March 2004 to December 2006, 47 consecutive patients with early stage NSCLC with a diameter of tumor less than 6 cm were recruited and randomized to VATS group and MT group. Incision length, duration of operation and intraoperative blood loss were recorded. Postoperative pain was assessed using a visual analogue scale before operation and daily for the first 7 days after operation. The serum levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured by cytometric bead array before operation and at 4, 24, and 48 h after operation. Karnofsky performance status (KPS) was assessed before operation and daily for the first 7 days after operation.</p><p><b>RESULTS</b>Incision length was (6.0 +/- 0. 9) cm in the VATS group and (12.5 +/- 1.5) cm in the MT group. There was no significant difference in duration of operation and intraoperative blood loss between the VATS group and the MT group. Postoperative pain was significantly less in the VATS group in the 5th to 7th day postoperatively (P < 0.05). There was no significant difference of serum concentrations of IL-6 and IL-10 between the VATS group and the MT group at 4, 24, and 48 h after operation. KPS score was significantly higher in the VATS group on 2nd to 7th day postoperatively (P < 0.05).</p><p><b>CONCLUSION</b>Compared with MT, VATS for lobectomy has less postoperative pain, faster recovery, but can't reduce postoperative release of cytokines.</p>
