Treatment for Lung cancer metastasis to the upper segment of the anterior superior and invading the anterior mediastinal area. 肺癌转移到前上段和侵犯前纵隔区的治疗。

After a year of ECCT usage, significant therapeutic outcomes were observed in a patient with lung cancer metastasis to the upper segment of the anterior superior and invading the anterior mediastinal area. Notably, the Carcinoembryonic Antigen (CEA) levels exhibited a remarkable decrease from 70 to 0.5.

经过一年的ECCT使用，观察到了肺癌转移到前上段并侵犯前纵隔区的患者的显著治疗效果。值得注意的是，癌胚抗原（CEA）水平从70降至0.5，呈现出显著的下降趋势。

This observed reduction in CEA levels highlights the effectiveness of ECCT therapy in managing lung cancer metastasis. The substantial decrease in CEA, a tumor marker associated with lung cancer progression, suggests a positive response to treatment and potentially indicates tumor regression or stabilization.

观察到CEA水平的降低突显了ECCT治疗在管理肺癌转移中的有效性。CEA的显著下降，作为与肺癌进展相关的肿瘤标记物，表明了对治疗的积极反应，并可能表明肿瘤的退缩或稳定。
