The optimal treatment of stage ⅢA-N2 non-small cell lung cancer (NSCLC) remains controversial. Resultsof primary surgery alone are not satisfied. Surgery after induction chemotherapy yields better outcomes compared to resectiononly which has been widely accepted. Randomized studies show induction chemotherapy followed by either radiotherapy or surgery have approximately equivalent survival outcomes,significant improved survival can be achieved by combined surgery in selected patients. Low-grade N2,effective response and mediastinal downstaging after induction therapy,and successful complete resection by lobectomy,are good indications of surgery. Ideal treatments are approached base on theheterogeneity of N2 . Patients with bulky or fixed N2 disease should be considered for radical chemo-radiotherapy,and surgeryshould be a part of multi-modality management for patients with non-fixed,non-bulky,single-zone N2 disease. Further randomized trials of surgery added to multi-modality management in patients with multi-zone N2 disease should be taken in order to establish possible subgroups of patients might be benefitted more from the addition of surgery.
目的 总结单心室瓣膜反流的外科治疗经验,观察治疗效果。 方法 回顾性分析2006年7月至2012年1月上海交通大学医学院附属新华医院61例单心室患者的临床资料,其中男36例,女25例;手术年龄2个月至 20岁;体重2~58 kg。右心室型41例,左心室型13例,未定型型7例。根据瓣膜反流程度不同分为3组,无/微量反流组:28例,瓣膜未行处理;轻/中度反流组:21例,瓣膜未行处理;重度反流组:12例,手术同期行瓣膜成形。收集所有患者住院及随访资料,分析轻/中度反流组、重度反流组瓣膜反流变化趋势,以及影响瓣膜反流的因素。结果 住院死亡5例,住院死亡率8.2% (5/61)。重度反流组患者行瓣膜成形术后反流程度较术前明显减轻(由术前4.00级下降至术后2.08级)。随访56例,随访时间6~38个月,重度反流组随访10例,随访期间死亡2例,其余8例中重度反流2例,中度反流3例,轻度反流2例,微量反流1例;瓣膜反流程度增加趋势明显(由术后平均2.08级增加至平均2.75级)。轻/中度反流组随访19例,随访中无死亡,其中反流程度增加至重度3例(原1例轻度反流,2例中度反流),反流程度由轻度增加至中度3例,瓣膜反流程度由术后平均2.33级增加为平均2.58级。轻/中度反流组瓣膜反流增加率与无/轻微反流组比较差异无统计学意义(瓣膜反流增加率为31.5% vs. 19.2%,χ2=0.36,P=0.55)。单因素分析结果显示,瓣膜反流增加者在随访过程中心功能较瓣膜反流无变化或减轻者明显降低(术后左心室射血分数53.11%±5.61% vs. 59.65%±3.32%,t =-5.49,P=0.00),而左心室舒张期末容积较瓣膜反流无变化或减轻者明显增加(t =2.58,P=0.01)。 结论 单心室合并重度瓣膜反流行瓣膜成形术近期效果较好,但随着心功能下降、心室扩张,瓣膜反流程度加重趋势明显;轻/中度瓣膜反流可暂不进行处理,但部分患者瓣膜反流有增加趋势,提示应注重术后随访。
Objective To summarize our experience of cardiovascular surgery for patients dependent on dialysis, and evaluate its safety and efficacy.?Methods?Clinical data of 10 consecutive patients dependent on maintenance dialysis underwent cardiovascular operations between Dec. 2004 and April 2011 in Peking Union Medical College Hospital were analyzed retrospectively. There were 6 male and 4 female patients, aged between 23 to 71 (57.6±13.2) years. They were put on dialysis 3-98 (25.2±30.6) months prior to operation due to diabetic nephropathy in 6 patients, chronic glomerulitis in 3 patients and systemic lupus erythemus in 1 patient, and 8 were dependent on hemodialysis and 2 on peritoneal dialysis. Five patients underwent coronary artery bypass grafting, one underwent Bentall procedure,two underwent aortic valve replacement, one underwent mitral valve replacement, and one underwent superior vena cava thrombectomy and patch repair. Patients underwent dialysis on the day before elective operation, followed by continuous ultra-filtration during cardiopulmonary bypass, and then bedside heparin-free continuous veno-venous hyperfiltration-dialysis started 5-32 hours after the operation. Conventional peritoneal dialysis or hemodialysis was resumed 4-7 days after operation.?Results?All operations were successfully completed. Cardiopulmonary bypass time was (125.8±33.5)minutes, aortic clamp time was(77.2±25.5) minutes. One in-hospital death occurred due to septic shock after deep chest wound infection. One patient underwent re-exploration due to pericardial temponade to achieve hemostasis. Three patients experienced atrial fibrillation and were all converted to sinus rhythm by amiodarone. Nine patients recovered to discharge and were followed-up for 8-76 months. Two late deaths occurred due to intracranial hemorrhage and liver carcinoma respectively. Seven survived patients were all in New York Heart Association grade II functional class, and none of them experience major advertent cardiac events related to grafts or prosthetic valve. One patient switched to hemodialysis 14 months after discharge due to peritonitis.Conclusion?Cardiovascular surgery can be practiced in patients dependent on maintenance hemodialysis or peritoneal dialysis with appropriate peri-operative management, so that symptoms can be relieved and quality of life improved.
