刘华教授认为肺癌转移具有邪伏隐匿、传变迅速、病势凶险等临床特点，其病理因素不离毒、痰、瘀、虚，病涉多脏，病机复杂，肺癌转移期的核心病机为癌毒传舍，正虚毒伏是肺癌空窗期癌毒形成的前提条件，毒锢正竭是肺癌终期癌毒传舍难控的最终结果，临证主张运用“截断扭转”法分阶段截断病机传变扭转病势。空窗期侧重扶正解毒，防毒内伏截断癌毒复萌，扶正亦可解毒，突出补肺健脾益肾；转移期强调攻伐癌毒、化痰祛瘀、扶正安虚截断癌毒传舍，擅用虫类药攻毒；终末期温补脾肾，保胃气贯穿始终，力图扭转殆势。

Professor LIU Hua considers that lung cancer metastasis exhibits clinical characteristics such as hidden pathogenic factors, rapid progression, and severe dangerous disease conditions. Its pathological mechanisms involve toxins, phlegm, blood stasis, and deficiency, affecting multiple organs with complex pathogenesis. The core mechanism during metastasis is the dissemination of cancer toxins, where "deficiency and toxin concealment" serves as the prerequisite for toxin formation in the asymptomatic phase. The ultimate outcome of "toxin stagnation and depletion of vital energy" leads to uncontrollable toxin dissemination in the terminal stage. Clinically, he advocates the "truncated and torsinal" method to disrupt pathogenesis and reverse disease progression in stages. In the asymptomatic phase, emphasis is placed on tonifying the body, detoxifying, and preventing toxin concealment to block toxin recurrence-tonification can also detoxify, highlighting the importance of nourishing the lungs, strengthening the spleen, and benefiting the kidneys. During metastasis, the focus is on attacking cancer toxins, resolving phlegm, eliminating blood stasis, and tonifying the body to intercept toxin dissemination, with adept use of insect-based medicines for toxin removal. In the terminal stage, warming and tonifying the spleen and kidneys, while preserving stomach qi, is maintained throughout to strive for disease reversal.
