目的 :明确胸膜腔冲洗液细胞学检查(PleuralLavageCytology ,PLC)在肺癌、食管癌外科临床中的意义。方法 :对32例肺癌和30例食管癌手术患者开胸后用200ml生理盐水冲洗胸腔并作细胞学检查。结果 :肺癌和食管癌PLC阳性率分别为15.6 %和20 %。PLC阳性率与患者性别 ,年龄 ,临床症状 ,病程 ,组织学类型 ,T、N分级及TNM分期等因素均无相关性 ,与食管癌病灶部位及病灶长度也无相关性。结论 :PLC可作为肺癌 ,食管癌的一个辅助分期和预后因素 ,同时也可作为一个术后辅助治疗的患者选择指标
Objective: To clarify the clinical significance of Pleural Lavage Cytology (PLC) in the surgical treatment of lung cancer and esophageal cancer. Methods: Thirty-two lung cancer patients and 30 esophageal cancer patients undergoing thoracotomy were rinsed with 200 ml normal saline and subjected to cytological examination. Results: The positive rates of PLC in lung cancer and esophageal cancer were 15.6% and 20% respectively. The positive rate of PLC had no correlation with the gender, age, clinical symptoms, course of disease, histological type, T, N grade and TNM stage, and had no correlation with the location of focal lesion and lesion length in esophageal cancer. Conclusion: PLC can be used as a secondary staging and prognostic factor for lung cancer and esophageal cancer, and can also be used as an index for patients with postoperative adjuvant therapy
