Radiation pneumonitis (RP) occurs in some patients treated with thoracic radiation therapy. RP often self-resolves, but when severe it is most commonly treated with corticosteroids because of their anti-inflammatory properties. Androgens and human growth hormone (HGH) also have anti-inflammatory and healing properties in the lung, but have not been studied as a remedy for RP. Here we present a case of corticosteroid-refractory RP that resolved with androgen and HGH-based therapy.
A 62 year old male body builder with excellent performance status presented with locally advanced non-small cell lung cancer characterized by a 7 cm mass in the right lower lobe and associated right hilar and subcarinal lymph node involvement. He was treated with chemoradiation and an excellent tumor response was observed. However, 2 months post-treatment he developed severe shortness of breath and imaging was consistent with RP. His RP was refractory to prednisone and antibiotic therapy, despite various regimens over a 9 month period. The patient self-treated with an androgen and HGH-based regimen and the RP promptly resolved.
The anti-inflammatory properties of androgens and HGH have prompted an exploration of their potential role in therapeutic strategies to treat pro-inflammatory conditions such as sepsis, infections and interstitial lung disease. This case study suggests a potential role for the use of androgens for the treatment of steroid-refractory RP after radiation therapy. However, the applicability of this strategy to general populations should be weighed carefully against secondary effects of these agents, especially in the setting of cancer survivorship.
放射性肺炎(RP)发生在一些接受胸部放射治疗的患者中。RP通常会自行缓解,但严重时,由于其抗炎特性,最常用皮质类固醇进行治疗。雄激素和人生长激素(HGH)在肺部也具有抗炎和愈合特性,但尚未作为RP的治疗方法进行研究。在此,我们报告一例皮质类固醇难治性RP患者,其通过基于雄激素和HGH的治疗得以缓解。
一名62岁男性健美运动员,身体状况良好,患有局部晚期非小细胞肺癌,其特征为右下叶有一个7厘米的肿块,并伴有右肺门和隆突下淋巴结受累。他接受了放化疗,观察到肿瘤有良好反应。然而,治疗后2个月,他出现严重气短,影像学检查与RP相符。尽管在9个月期间采用了各种方案,他的RP对泼尼松和抗生素治疗均无效。该患者自行采用基于雄激素和HGH的方案进行治疗,RP迅速缓解。
雄激素和HGH的抗炎特性促使人们探索它们在治疗脓毒症、感染和间质性肺病等促炎病症的治疗策略中的潜在作用。本病例研究表明,雄激素在放疗后治疗类固醇难治性RP方面可能具有潜在作用。然而,应仔细权衡该策略对一般人群的适用性与这些药物的副作用,尤其是在癌症幸存者的情况下。
