  • Recent Progress in Individualized Therapy of Colorectal Cancer

    结直肠癌是一种严重威胁我国国民生命的恶性肿瘤,近年来其发病率呈不断上升的趋势。根据WHO报告的资料[1]显示,我国结直肠癌死亡率2005年比1991年增加70.7%,年均增加4.71%。尽管对结直肠癌的病因学研究和以手术切除、放射治疗和化学药物治疗为主的综合治疗取得了一定进展,但结直肠癌的治疗仍然面临巨大挑战。对不同个体采用相同的治疗方案不仅不能提高治疗效果,而且造成医疗资源的浪费,甚至给患者带来伤害。目前,个体差异与疗效的关系越来越受到临床医生和研究者的重视。随着循证医学的不断发展,结直肠癌的个体化治疗日益成为临床治疗及基础研究的重点。结直肠肿瘤多学科协作(multidisciplinary team,MDT)诊治模式的运用为结直肠癌个体化诊治提供了新的平台[2]。....................

  • Clinical efficacy of two micro-portal video-assisted thoracic surgery in pulmonary lobectomy for lung cancer

    ObjectiveTo analyze the surgical outcome of patients with lung cancer using double micro-portal video-assisted thoracic surgery (VATS) technique.MethodsWe retrospectively analyzed the perioperative data of 200 patients with primary lung cancer who underwent successful two micro-portal VATS lobectomy between September 2016 and June 2018 at our unit. There were 125 males and 75 females, aged 61.01±8.71 years. The length of the main operating hole was about 2.0–2.5 cm, the size of the secondary operating hole and the observation hole was 0.5 cm individually. Thus, the total length of the three incisions was 3.0–3.5 cm.ResultsThe mean operating time was 99.18±21.77 min, blood loss was 170.35±105.12 ml, and the mean number of dissected lymph node was 15.82±3.33. The mean volume and duration of chest tube were 446.90±195.32 ml and 3.67±1.85 days. The postoperative hospital stay was 5.54±2.41 days. Only one patient died of pulmonary embolism after surgery. There were 7 patients who were converted to thoracotomy. Postoperative pulmonary infection after lobectomy was found in 8 patients. Postoperative air leak over 5 days was developed in 7 patients.ConclusionThe double micro-portal VATS procedure is a safe and effective strategy for patients with lung cancer, which is associated with decreased surgical trauma and less postoperative pain. This emerging technology may benefit patients by enhancing comfort during their postoperative hospitalization.

  • Clinical analysis for the short-term outcome of Da Vinci robotic-assisted left upper lobectomy for lung cancer

    ObjectiveTo summarize the clinical experience of Da Vinci robotic-assisted left upper lobectomy for treating lung cancer.MethodsWe retrospectively analyzed the perioperative data of 33 patients with primary lung cancer who underwent Da Vinci robotic-assisted left upper lobectomy between December 2016 and December 2018 in our hospital. Meanwhile, the perioperative data of 41 patients with lung cancer who underwent video-assisted thoracoscopic left upper lobectomy during the same period by the same surgeon were studied as a control group. The resection was followed by the principle of "from back down to front up" way. Systemic lymph node dissection including No.4-9 was performed for all patients.ResultsAll patients received successful surgery with no case of conversion to thoracotomy and perioperative death. Comparing to video-assisted thoracoscopic surgery, the Da Vinci robotic-assisted left upper lobectomy had longer operating time (191.21±61.77 min vs. 154.51±38.81 min, P=0.003), more cost (82 307.75±11 859.03 yuan vs. 58 966.57±5 640.07 yuan, P=0.000), shorter chest tube duration (4.58±1.77 d vs. 5.41±1.52 d, P=0.031) and postoperative hospital stay (6.48±1.82 d vs. 7.66±2.12 d, P=0.014). However, there was no significant difference between the two groups regarding to blood loss, lymph node dissection, postoperative pain score, total chest drainage volume, chest drainage volume per day and the rate of pulmonary complications.ConclusionThe Da Vinci robotic-assisted left upper lobectomy for treating lung cancer is safe and more minimally invasive, but more expensive.

  • Detecting Plasma Epidermal Growth Factor Receptor Mutations of 198 Patients with Surgically Resected Non-small Cell Lung Cancer by Amplification Refractory Mutation System

    ObjectiveTo reveal the true value of plasma detection of epidermal growth factor receptor (EGFR) mutation for early-stage non-small cell lung cancer (NSCLC) gene diagnosis and to predict survival prognosis. MethodsTissue samples of positive EGFR mutations by using amplification refractory mutation system (ARMS) method were surgically resected from 198 patients with stage I-IV NSCLC between February 2014 and June 2015 in Tangdu hospital. Paired blood samples were collected before surgery. And the cellfree DNA (cfDNA) in plasma was extracted, plasma EGFR mutations were detected by real-time polymerase chain reaction (PCR). Concentration of cfDNA was measured by ultraviolet spectrophotometry. Follow-up observation for stage ⅢA patients was put into force after surgery. Kaplan-Meire was used in survival analysis. ResultsThe sensitivity of EGFR mutation for the 198 paired tissues and plasma samples was 17.2%.The sensitivity was positively correlated with TNM stage and negatively correlated with tumor differentiation. The sensitivity of sage ⅢA was 33.3%, significantly higher than that of the patients at stage ⅠA (1.6%, P=0.000) and stage ⅠB (7.9%, P=0.004). The sensitivity of poor differentiation was 36.8%, significantly higher than that of high differentiation (0.0%, P=0.000) and moderate differentiation (15.7%, P=0.010). There was no correlation between plasma cfDNA concentration and patient characteristics. Survival analysis showed that plasma detection was a vital factor for predicting postoperative survival prognosis of stage ⅢA patients (P=0.014). ConclusionTissue samples cannot be replaced by plasma samples for epidermal growth factor receptor (EGFR) mutation test in early-stage NSCLC patients, currently. When the sensitivity increases dramatically in the plasma samples of stage ⅢA NSCLC and poor differentiation tumor, we recommend using plasma detection for gene diagnosis, dynamic monitoring of EGFR mutations in stage ⅢA or poorly differentiated tumors, especially in NSCLC patients whose tissue samples cannot be obtained by surgery. And plasma EGFR detection is a valuable method of forecasting survival prognosis for locally advanced NSCLC patients.
