目的 分析评价X线胸片(PCR)对肺癌分期的能力。方法 对90例经组织学诊断确认的肺癌进行回顾性分析,与PCR诊断结果进行对比。结果 PCR对肺癌临床分期(cTNM)与病理分期(pTNM)相一致的占622%;判断可切除的和不可切除的肺癌准确性为733%。对不能手术的病例(533%)具有决定诊断意义的表现为主支气管罹病(T3、T4),胸水(T4),纵隔淋巴结转移(N2、N3)等;其次胸外转移和内科情况均为不能手术的重要前题。结论 PCR对肺癌分期的准确性较高,并且经济、简便,目前仍为临床诊断肺癌的首选检查方法。PCR的缺点是准确证实肿瘤浸润胸膜(壁)、纵隔(T3、T4)、纵隔淋巴结转移(N2、N3)及胸外转移(M1)等有一定限制。
Objective To analyze and evaluate the ability of X-ray to staging lung cancer. Methods Ninety cases of lung cancer confirmed by histological diagnosis were retrospectively analyzed and compared with the results of PCR diagnosis. Results The PCR was consistent with the clinical staging of lung cancer (cTNM) and pathological stage (pTNM), accounting for 622%. The accuracy of resectable and unresectable lung cancer was 733%. Of the inoperable cases (533%), the diagnosis of bronchial asthma (T3, T4), pleural effusion (T4), mediastinal lymph node metastasis (N2, N3) An important prerequisite for surgery. Conclusion PCR is more accurate for lung cancer staging, and it is economical and simple. It is still the first choice for clinical diagnosis of lung cancer. The disadvantage of PCR is the accurate confirmation of tumor infiltration pleural (wall), mediastinal (T3, T4), mediastinal lymph node metastasis (N2, N3) and chest metastasis (M1) and so there are some restrictions.
