Therefore, the contribution of steroids to the reported response rates in these studies remains uncertain. Furthermore, steroid sparing should be an important goal of salvage therapy of cGVHD. Because no predictors of response are yet available either for solitary immunosuppressive providers or combination treatments, most individuals receive empirical treatment in daily medical practice and changes of therapeutic parts in case of lack of response are performed at the individual clinician’s discretion [52]. 2.2. TKIs Can Be Safely Administered after Allogeneic SCT TKIs are a class of medicines comprising small molecule inhibitors of oncogenic tyrosine kinases (TK), which have recently been developed for treating several malignancies. Among these medicines, Imatinib Mesylate showed a specific inhibitory effect on CML cells and BCR-ABL-transformed cells both in tradition and when produced as tumors in mice. Since 1986, phase II clinical tests showed that Imatinib was effective in treating chronic phase CML, and up to day this drug is the most mainly used in CML with 100,000 individuals treated. Imatinib not only inhibits BCR-ABL but also is almost equally potent against PDGFRand c-KIT receptor tyrosine kinases [80]. c-KIT receptor TK is definitely implicated through activating mutations in GIST [81]; indeed, Imatinib and additional TKIs are effective also in individuals with GIST [82]. Imatinib has also been tested in the treatment of additional malignant hematopoietic diseases, including hypereosinophilic syndrome and chronic eosinophilic leukemia, which also express an triggered form of PDGFR[83]. Finally, some reports suggest a limited efficacy of these drugs in individuals with systemic mastocytosis with 816 KIT mutations, causing constitutive activation of TK activity of the molecule [84]. More recently, this drug has been also tested in individuals with autoimmune diseases and cGVHD (observe later). The acute and chronic security profile of TKIs has been extensively evaluated in CML individuals, and the most analyzed drug is definitely Imatinib [85]. A common observation is definitely that in individuals with early disease, the hematological toxicity is definitely slight, while relevant myelosuppression has been reported in individuals with advanced disease [86]. Common extrahematological toxicities that have been reported with Imatinib include 21-Hydroxypregnenolone nausea, vomiting, diarrhea, fatigue, muscle mass aches, fluid retention, and pores and skin rash [87]. The concern that Imatinib may lead to more severe toxicities such as cardiac heart failure was first reported by Kerkela et al. [88] Subsequently, the issue of Imatinib-related cardiac toxicity in the non-SCT establishing has been addressed by several investigators [89C91]. In each of these reports, cardiac failure and remaining ventricular dysfunction, 21-Hydroxypregnenolone which was probably or probably related to Imatinib therapy, were either not recognized [89] or were found to occur hardly ever (0.04%/12 months) as with the International Randomized Study of Interferon and ST1571 trial [90]. In conclusion, since the initial 21-Hydroxypregnenolone report, no further evidence to support an increased risk of cardiac toxicity offers emerged with Imatinib [92]. Nilotinib and Dasatinib have a different toxicity profile that has been extensively analyzed in CML individuals [93, 94], but there are still few data concerning the safety of these drugs outside the establishing of CML, especially in individuals undergoing allogeneic SCT. Some experiences with Imatinib suggest that TKIs use in the peritransplant period experienced no effect on either TRM or cardiac toxicity, while the potential myelosuppressive effects of Imatinib could be relevant, with standard doses.
