We investigated the levels of TGF-beta in malignant pleural effusions (MPE) caused by malignant mesothelioma (MESO) or primary lung cancer. TGF-beta levels in MPE caused by MESO were 283.9 +/- 219.2 pm (mean +/- s.d.) and were three to six times higher than those due to primary lung cancers (P < 0.01 or P < 0.05). We also evaluated TGF-beta 1- and beta 2-like activities in MPE using specific polyclonal antibodies. Although TGF-beta 1-like activity could be detected in all cases, TGF-beta 2-like activities were detected in five of seven in MESO and in a few cases with primary lung cancer. These results demonstrate that the levels of total TGF-beta and TGF-beta 2-like activity may be clinically useful to differentiate MESO from primary lung cancer. Our data also suggest that TGF-beta may help further characterize the clinical features of MESO.
我们研究了恶性间皮瘤(MESO)或原发性肺癌所致恶性胸腔积液(MPE)中转化生长因子-β(TGF-β)的水平。MESO所致MPE中TGF-β水平为283.9±219.2皮摩尔(均值±标准差),比原发性肺癌所致者高3至6倍(P<0.01或P<0.05)。我们还使用特异性多克隆抗体评估了MPE中TGF-β1和β2样活性。虽然在所有病例中均可检测到TGF-β1样活性,但在MESO的7例中有5例以及少数原发性肺癌病例中检测到了TGF-β2样活性。这些结果表明,总TGF-β水平和TGF-β2样活性在临床上可能有助于鉴别MESO和原发性肺癌。我们的数据还提示,TGF-β可能有助于进一步明确MESO的临床特征。
