Although evidence supports the efficacy of reducing immunosuppression for transplant-associated skin cancer, clinical thresholds for and risks associated with reduction are not well defined.
In this study, experienced transplant physicians were surveyed regarding appropriate thresholds for consideration of reduction of immunosuppression and the likelihood of rejection and allograft compromise associated with various levels of reduction.
Fifty-two transplant physicians reviewed 13 hypothetical patient scenarios with graduated morbidity and mortality risk and provided opinions on the degree of reduction of immunosuppression that was warranted and the risks associated with various degrees of reduction.
Renal, liver and cardiac transplant physicians generally concurred on the level of reduction of immunosuppression warranted by various degrees of skin cancer. As morbidity and mortality from skin cancer increased, physicians were more likely to accept risk to allograft function from more aggressive reduction.
Reduction of immunosuppression is considered a reasonable adjuvant strategy in recipients of solid organ transplants who have substantial morbidity and mortality risk from skin cancer. Physicians are willing to accept an increased risk of allograft compromise when confronted by severe or extensive skin cancer. Further research is needed to define the precise correlation among levels of reduction of immunosuppression, therapeutic efficacy, and concomitant risks.
尽管有证据支持降低免疫抑制对移植相关皮肤癌的疗效,但降低免疫抑制的临床阈值及相关风险尚未明确界定。
在本研究中,针对经验丰富的移植医生进行调查,了解考虑降低免疫抑制的适当阈值以及与不同程度降低相关的排斥反应和移植物受损的可能性。
52名移植医生审阅了13个具有递增发病率和死亡率风险的假设患者病例,并就有必要降低免疫抑制的程度以及不同程度降低相关的风险发表意见。
肾移植、肝移植和心脏移植医生对于不同程度皮肤癌所对应的免疫抑制降低水平普遍达成共识。随着皮肤癌发病率和死亡率的增加,医生更有可能接受更积极降低免疫抑制对移植物功能造成的风险。
对于因皮肤癌面临较高发病和死亡风险的实体器官移植受者,降低免疫抑制被认为是一种合理的辅助策略。当面对严重或广泛的皮肤癌时,医生愿意接受移植物受损风险增加的情况。需要进一步研究来明确免疫抑制降低水平、治疗效果和伴随风险之间的确切关联。
