Sentinel node lymphadenectomy can be better accomplished when both procedures (lymphatic mapping with Patent Blue-V and RGS) are used because the two methods look quite complementary. In fact, the use of the radiocolloid mapping allows to detect a hot spot in the regional basin prior to making the skin incision in order to perform a minimal invasive access, and it may also more accurately differentiate the true sN from a secondary echelon node (non-sN). The use of frozen section examination should be restricted to patients with pT(3)-pT(4) primary melanoma, due to the higher sensitivity and benefit in terms of avoiding a two-stage operative procedure.
Outpatient treatment with TIL plus rIL-2 and rIFN-alpha2a is feasible, although, within the context of the small sample size, the activity of the combination was no different from the reported activity of any of the components used alone.
These preliminary findings suggest a similar efficacy, coupled with less morbidity, of postoperative RT alone compared with a combined regimen of postoperative RT and CT in patients undergoing radical surgery for stage II-III rectal cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
