Efficacy of sunitinib re-exposure after failure of an mTOR inhibitor in patients with metastatic RCC.

Background: The sequential use of tyrosine kinase inhibitors (TKI) followed by mTOR inhibitors (mTORi) has been recently established for the systemic treatment of metastatic renal cell carcinoma (mRCC). However, subsequent treatment in mTORi-refractory disease remains undetermined. We analyzed the efficacy of sunitinib re-challenge after failure of an mTORi at 2 German centers.

Results of a randomized, placebo-controlled safety and efficacy study of topical diclofenac 3% gel in organ transplant patients with multiple actinic keratoses.

Increasing incidence rates of cutaneous malignancies, paralleling rising survival times of grafts and patients in organ transplant recipients, represents an escalating challenge for dermatologists worldwide. Especially, invasive squamous cell carcinomas (SCC) in immuno-compromised patients are characterized by significantly increased morbidity and mortality and characteristically outnumber basal cell carcinoma in this population. Effective management of actinic keratoses (AK) could help to prevent the further development of invasive SCC.
