Standard Posterolateral Thoracotomy: 傷口大, 恢復慢, 長期疼痛比例高
胸腔鏡手術器械配置圖及傷口 器械入口 器械入口 內視鏡
胸腔鏡手術 : 優點 胸腔鏡肺葉切除術後之肺功能影響較小 胸腔鏡手術引發較少之發炎反應, 對免疫功能較好 胸腔鏡肺葉切除術後長期生活品質較好 1. Kaseda S. Ann Thoracic Surg, 2000 2. Leaver HA. Eur J Clin Investi, 2000 3. Sugiura H. Surg Laparo Endo, 1999
肺葉切除術 : 胸腔鏡或開胸手術? 目前胸腔鏡肺葉切除術已經有許多醫學中心使用於肺癌之手術治療. 安全性 : 與開胸手術類似, 甚至更好 腫瘤學方面考量 (JCO 2009 metaanalysis): 局部復發率沒有差別 遠處轉移率較低 5 年死亡率較低 Yan TD. J Clin Oncol 2009.
VATS versus Thoracotomy for Lung cancer: NTUH experience Retrospective study: 1997-2006 768 patients with lung cancer undergoing curative resection at NTUH 344 patients were excluded stage III and IV tumor size > 5 cm, undergoing wedge resection, sleeve lobectomy or pneumonectomy. Only 424 patients undergoing lobectomy or bilobectomy were included for analysis.

Conclusion and Discussion VATS lobectomy is a safe alternative to posterolateral thoracotomy in treating lung cancer patients Comparable complication and mortality rates Long-term survival: unclear by multivariate analysis Further prospective studies are required

Multimodality Approach in Patients with Stage-III Resectable Non-Small Cell Lung Cancer: Literature Review and the Experience of National Taiwan University Hospital
Stage III Resectable Disease: Disappointing long-term outcome by surgery only" approach Pre-op positive mediastinal nodes: 5% 5-y survival Intra-operative multilevel nodal involvement: 11% 5-y survival Distant metastasis in 80% of cases with relapse Systemic treatment with combined modality for better control of both local and disseminated diseases is indicated Andre F, JCO 2000;18:2981
Multimodality Approach for Stage III Resectable NSCLC Neoadjuvant Adjuvant Chemotherapy Chemotherapy Diagnosis & Staging Radiotherapy Surgery Radiotherapy Target therapy Target therapy Increase resectability Eradicate distant micromets Decrease the residual tumor Eradicate distant micromets
Theoretical Advantage of Neo- adjuvant Chemotherapy Better compliance & all patients eligible (many don't receive adjuvant CT after surgery) Reduce tumor burden Downstages: Mediastinal lymph node clearance More complete resection Earliest treatment of micro-metastatic disease

Neoadjuvant C/T + Surgery + Adjuvant C/T with Docetaxel+Cisplatin,, NTUH (2004-2005) 2005) Results (39 patients) Overall response rate: 69.3% Surgery performed in 35 patients (89.7%) No operation mortality or major morbidity Median follow-up: 49 months Recurrence: 62.9% 3 year overall survival: 75.9% univariate analysis: early recurrences were correlated with female gender (p=0.024), age < 60 years (p=0.044), adenocarcinomas (p=0.005), and increased number of residual metastatic lymph nodes (p=0.022). Multivariate analysis: adenocarcinoma was the strongest factor for early recurrences over squamous cell carcinoma (p=0.0242).
Conclusions (2003-2005) 2005) : Combination of neoadjuvant C/T + surgery +/- adjuvant C/T with Doc+CDDP provides a safe and feasible alternative for stage III NSCLC patients 3-year overall survival: satisfactory Adenocarcinoma was an independent factor for early recurrences over squamous cell carcinoma
Adjuvant Chemotherapy for Lung Cancer
(1867 patients): IALT Trial (1867 patients): Cisplatin-based adjuvant C/T improves survival with completely resected NSCLC Especially for stage III patients (IALT. NEJM 2004;350:351)
結論 :Cisplatin: Cisplatin-based adjuvant C/T is suggested for stage II and III disease Goodgame B. J Thorac Oncol 2009.
