Management of Non-melanoma Skin Cancer in Transplant Recipients

Transplant recipients have a significantly higher risk of developing non-melanoma skin cancers compared with the general population and squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the most common post-transplant malignancies. Although in the general population BCC outnumbers SCC 4:1, in transplant patients this ratio is reversed and SCC is more common, with a 65- to 250-fold increased incidence. As patients in immunosuppressed states are living longer after transplants, the incidence of skin cancer in this population continues to increase. The skin cancers in transplant patients also tend to be more aggressive, with higher morbidity and mortality. Preventive strategies play an important role in transplant recipients given their increased frequency of developing both premalignant and malignant skin lesions. Sun protection and regular skin cancer screening are critical. In addition, chemoprophylaxis with systemic retinoids, nicotinamide and capecitabine can significantly reduce the development of new skin cancers. Topical 5-fluorouracil, imiquimod, photodynamic therapy and cyclooxygenase inhibitors have all been investigated in transplant patients for the treatment of field cancerisation. Adjusting the immunosuppressive regimen is also an important adjuvant therapeutic strategy for managing skin cancers in transplant recipients and requires integrated multidisciplinary care with the entire transplant team. This article reviews the epidemiology of non-melanoma skin cancer in transplant patients, discusses the prevention strategies and highlights the management and treatment strategies of both field cancerisation and non-melanoma skin cancers.     

论湿为病毒

王辉武教授临床观察认为“湿邪”可能与现代医学所说的“病毒”相类似,中医中药以祛风除湿、芳香化湿、苦温燥湿、淡渗利湿、健脾驱湿等治疗病毒性疾病均有明显疗效,可见“湿”为治疗核心,故大胆提出“湿为病毒”学术观点,并进行了多年的理念论证和临床验证。本文运用中医湿邪理论,探讨论证病毒性疾病与湿邪的相关性,希望有益于病毒性疾病的辨识,便于对疾病的早期干预,防止进一步恶化,以求丰富中医防治病毒性疾病的理念。
