The efficacy of an LTSL formulation of docetaxel (DOC) or doxorubicin (DOX) was compared against prostate cancer in a xenograft mouse model. METHODS Under an approved IACUC protocol, Luciferase transfected human prostate PC-3M-luciferase cells were inoculated (3×106 cells) subcutaneously in the right hind leg of 8 wk old female athymic nude mice. When tumors reached a volume of 200–300 mm3, mice were randomized to receive one intravenous injection of saline, Stealth liposomal DOX (5 mg/kg), LTSL DOX (5 mg/kg), or LTSL DOC (15 mg/kg), with or without hyperthermia treatment (LTSL DOX and LTSL DOC were supplied by Celsion Corp., Columbia, MD). Mice undergoing hyperthermia treatment were anesthetized and stabilized in a holder that allowed for only the leg with tumor to be heated to 41–42C that triggered LTSL drug release. Mice were monitored daily for tumor volume and body weight. Study end-points included growth of tumor to 5x the initial treatment volume or monitoring of survival for 60 days. RESULTS The LTSL DOC delayed tumor growth longer (20 days) than DOX (7 days) or LTSL DOX (9 days) with hyperthermia (P<0.05). Mice treated with LTSL DOC and hyperthermia survived longest (60 days) compared to all other mice (range 6–8 days, P<0.05). LTSL in the setting of hyperthermia demonstrated complete regression of tumor in 57% of mice. CONCLUSIONS LTSL DOC with hyperthermia delayed tumor growth more than all other treatments. Survival studies suggest LTSL DOC is a more effective temperature sensitive delivery system against PC-3M prostate tumors. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e651 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.MetricsAuthor Information Saurin Chokshi Bethesda, MD More articles by this author Compton Benjamin Bethesda, MD More articles by this author Ashish Ranjan Bethesda, MD More articles by this author Paul Chung Bethesda, MD More articles by this author Ayele Negussie Bethesda, MD More articles by this author Ardeshir Rastinehad Bethesda, MD More articles by this author Katherine Klos Bethesda, MD More articles by this author Matthew Dreher Bethesda, MD More articles by this author W.
