摘 要:目的探讨肿瘤侵及血管与肺癌患者运动心肺功能改变之间的相关性。方法对405例肺癌患者(经CT或手术证实无血管受侵者112例,有血管受侵者293例)行运动心肺功能测定,主要观察指标为终止负荷运动时最大运动负荷占预计值百分比(W%)、最大千克摄氧黾(VO2/kg)、无氧阈(AT)、最大氧脉搏实测值占预计值百分比(VO3/HR%)、最大通气量(VE)、最大呼吸储备(BR)、最快呼吸频率(BF)和最大呼气潮气量(VTex)。结果血管受侵患者W%、VO2/kg、AT、VO2/HR%[分别为(73±18)%、(17±5)ml·min^-1·k^-1、(51±14)%、(79±18)%)]明显低于无血管侵犯患者[分别为(86±20)%、(19±5)ml·min·kg^-1、(55±14)%、(88±20)%,均P〈0.01],BF明显高于无血管受侵患者[(32.1±6.1)比(30.6±5.1)次/min,P〈0.05]。将血管受侵患者按TNM分期、受侵血管数目、种类及其与肿瘤的关系等分别分组进行比较,发现受侵血管为1、2、≥3支的患者W%、VO2/HR%均明显低于对照组(均P〈0.01),1支组和≥3支组AT明显低于对照组(P〈0.05,P〈0.01);2支组和≥3支组VO2/kg明硅低于对照绀(P〈0.05,P〈0.01);≥3支组VO2/kg明显低于1支组和2支绀(P〈0.05或P〈0.01),VO2/HR%明显低于1支组(P〈0.05),VTex低于对照组和1支组(P〈0.05)。VO2/HR%与受侵血管支数有相关忡(r=0.220,P〈0.01)。结论有血管受侵的肺癌患者摄氧量、运动能力、运动心功能降低,受累血管数目是影响患者运动心肺功能的主要原因。Objective To investigate the correlation between the tumor vascular invasion and the change of cardio-puhnonary exercise function in patients with tung cancer. Methods The cardio-pulmonary exercise test was performed in 405 patients with lung cancer (293 with vascular invasion and 112 without). The peak load indices examined included maximal work power ( measured value/predicted value, W% ) , maximal oxygen uptake per weight ( VOe/kg) , anaerobic threshold ( AT), maximal oxygen pulse ( measured value/predicted value, VO2/HR% ), maximal minute ventilation (VE), maximal breath reserve (BR), maximal breath frequency(BF) and maximal tidal volume dining expiration (VTex). Results ( 1 ) W%, VO2/kg, AT, VO2/HR% of patients with vascular invasion [ (73 ± 18 ) % , ( 17 ±5 ) ml · min ^-1 · kg^-1, (51 ± 14) %, (79 ± 18 ) % respectively ] decreased than those without vascular invasion [ ( 86 ± 20) %, (19±5) ml· min^-1 · kg^-1, (55±14)%, (88 ±20)% respectively, all P〈0.01) while BF increased [ (32.1 ± 6. 1 )/min vs (30. 6 ± 5.1 )/min, P 〈 0. 05 ). (2) The patients were divided according to TNM stage, number, kind of tumor vascular invasion and its relationship with tumor, W% ,VO2/HR% decreased in the groups of 1-, 2- and ≥3-vessel invasion versus the control group (P 〈0. 01 ), AT decreased in the groups of 1- and ≥3-vessel invasion versus the control group ( P 〈0. 05, P 〈0. 01 ) , VO2/kg decreased in the groups of 2- and ≥3-vessel invasion versus the control group ( P 〈0. 05, P 〈0. 01 ) , VO2/kg decreased in the group of ≥3-vessel invasion versus 1- and 2-vessel invasion (P 〈0. 05 or P 〈0. 01 ) , VO2/HR% decreased in the gronp of ≥3-vessel invasion versus 1-vessel invasion (P 〈 0. 01 ), VTex decreased in the group of ≥ 3-vessel invasion versus the control group and 1-vessel invasion (P 〈 0. 05 ). There was correlation between V O2/HR% and the number of tumor invaded v
