目的：：探究手术切除T4期肺癌的临床疗效。方法：选择我院2011年5月至2015年12月收治的40例手术切除T4期肺癌患者为研究对象，总结这40例患者的资料，并且统计对患者生存率造成影响的因素，主要是治疗因素、病理因素以及临床因素等，对其进行统计、整理、分析以及比较。结果：这40例手术切除T4期肺癌患者，年龄小于63岁的患者在手术之后三年或者是五年里存活率明显高于大于63岁的患者的存活率，手术中全部切除的患者在手术之后三年或者是五年里存活率明显高于手术中部分切除患者的存活率，根治切除的患者在手术之后三年或者是五年里存活率明显高于手术中没有根治切除患者的存活率，有淋巴结转移现象的患者在手术之后三年或者是五年里存活率明显高于手术中没有淋巴结转移现象患者的存活率。结论：手术切除T4期肺癌患者预后直接和根治切除与否、淋巴结手否转移、手术切除的范围以及患者的年龄有关系。“,”Objective To explore the clinical effect of surgical treatment for stage T4 lung cancer. Methods Choose our hospital from may 2011 to December 2015 for 40 cases of surgical resection of T4 stage lung cancer patients as the research object, summarizes the 40 cases of patients, and the statistical impact factors on the survival rate, mainly treatment factors, pathological factors and clinical factors, the statistics, collation, analysis and comparison. In survival in patients after surgical resection. Results The 40 cases of T4 stage lung cancer patients aged less than 63 year old patients in three years or five years survival rate was significantly higher than that of more than 63 year old patient survival rate, surgical resection of all patients in surgery after three years or five years survival rate was significantly higher than that of surgery resection patients survival rate and radical resection surgery after three years or five years survival rate was significantly higher than that of surgery without the radical resection rate and lymph node metastasis of patients after operation for three years or five years survival rate was significantly higher than that of surgery without lymph node metastasis patients survival rate. Conclusion The postoperative prognosis of patients with stage T4 lung cancer and radical resection and lymph node metastasis is related to hand, the scope of the surgical resection and the age of patients.
