BACKGROUND: Former systemic therapy for metastatic renal cell cancer (mRCC) based on immunomodulation could achieve complete remissions (CR) in only some patients. Angiogenic therapy with sunitinib, sorafenib, and temsirolimus changed the paradigm of treating mRCC based on a doubled progression-free survival (PFS) and 10% to 30% of patients achieving partial remission (PR). Unfortunately, CR is rarely seen. Within our patients we could achieve some CR, which we are presenting in this study. PATIENTS AND METHODS: We assessed 194 consecutive patients of an institutional database that were treated for mRCC with either sorafenib or sunitinib between 05/2006 and 12/2007. Restaging with repeated high-resolution computed tomography (CT) of thorax and abdomen was performed in an 8 to 10 weeks interval. Five patients who achieved CR in repeated CT under therapy are included in this analysis. RESULTS: Of the patients in whom we achieved CR, two were female and three were male. Median age was 63.2 years (range 52-70). All patients had clear cell histology. In three of the five patients, CR was achieved by surgery after partial remission, and in two patients it was achieved by sole medical therapy. All patients remained in CR until now with a median duration of CR of 24 months (range 24-29 months). One patient still is on therapy, while four patients do not receive any systemic treatment. CONCLUSIONS: We proof long-term confirmed CR in mRCC achieved by anti-angiogenic therapy alone or in combination with surgery. Combining surgery and anti-angiogenic therapy based on sorafenib and sunitinib could render patients free of disease even after repeated cycles of systemic treatment. Copyright 2010 Elsevier Inc.
