Safety profile and therapeutic efficacy of one cycle of Lu177 PSMA in end stage metastatic castration resistant prostate cancer patients with low performance status

Conclusions: We concluded that Lu177 PSMA therapy has adequate pain palliation in all end-stage mCRPC patients and it has the potential to become an effective therapeutic option in properly selected patients. Keywords: Lu177 PSMA, Safety, efficacy, mCRPC, Low-performance status

ConclusionsRadium-223 was generally well tolerated and there were no safety concerns. The adverseevents were mild and manageable. A decline in serum alkaline phosphatase was more frequent than a decline in the prostate-specific antigen. Monitoring changes in serum alkaline phosphatase dynamics may be useful.ResumenEl dicloruro de Ra223 es un radiofármaco emisor alfa que prolonga la supervivencia global en pacientes con cáncer de próstata resistente a la castración y metástasis óseas sintomáticas.

Conclusions: TANDEM-PLRT, concomitantly administering Ac-225 and Lu-177 PSMA-617, seems to be feasible, safe and effective in end-stage metastatic prostate cancer, refractory to Lu-177 PSMA. The administered radioactivity of Ac-225 PSMA can be lowered and the risk of dose-limiting toxicity (xerostomia, xerophthalmia etc.) be minimized. There might be a potential synergistic effect using two radionuclides with different emission characteristics.

In conclusion, we identified a novel Bcl-2 inhibitor by QSAR screening, which exerted significant cytotoxic activity in breast cancer cells through inducing mitochondria-mediated apoptosis. Introduction Apoptosis is a process of cellular suicide through which unwanted or unhealthy cells are eliminated during organism development or cellular stress (Reed, 2002; Fernald and Kurokawa, 2013). Deregulated apoptosis is a characteristic of cancers (Doi et al., 2012; Roizen, 2012). The B-cell lymphoma-2 (Bcl-2) family is composed of pro- and anti-apoptotic proteins, plays pivotal role in the mitochondrial pathway of apoptosi...

Conclusions. This LuPSMA Phase II trial provides evidence of high response rates, pain reduction and low toxicity in men with mCRPC who progressed after conventional therapies. These compelling results indicate the need for randomised trials comparing LuPSMA to existing standard-of-care.

ConclusionCombined treatment with rhenium-188-HEDP and docetaxel did not prolong PFS in patients with CRPC. The observed survival benefit in the per-protocol analysis warrants further studies in the combined treatment of chemotherapy and radiopharmaceuticals.

cute;nyi K, Rúzsa Á, Géczi L Abstract Radium-223 dichloride is an alpha-emitting radiopharmaceutical which significantly prolongs overall survival in patients with castration-resistant prostate cancer (CRPC) and symptomatic bone metastases. This was a retrospective analysis of the efficacy and safety of Radium-223 in the first 41 patients treated at a single center in Hungary. Radium-223 was given at a dose of 50 kBq/kg intravenously every 4 weeks for up to 6 cycles. Between 23rd July 2014 and 23rd February 2016, 41 patients were treated. Patient demographics, laboratory values,...

BACKGROUNDWe sought to identify potential clinical variables associated with outcomes after radium‐223 therapy in routine practice. METHODSConsecutive non‐trial mCRPC patients who received ≥1 dose of radium dichloride‐223 at four academic and one community urology‐specific cancer centers from May 2013 to June 2014 were retrospectively identified. Association of baseline and on‐therapy clinical variables with number of radium doses received and clinical outcomes including overall survival were analyzed using chi‐square statistics, cox proportional hazards, and Kaplan–Meier methods. Bone Scan Index (BSI)...

Conclusions Overall, pain response percentages greater than 50–60% were seen with each radionuclide. Haematological toxicity was reported in 26 of the 36 studies and more than half of these trials stated no grade 3/4 leukopenia or thrombocytopenia occurred. Patient summary In this report we reviewed the efficacy of bone-seeking radionuclides for treating bone pain from metastatic prostate cancer. Overall, treatment with bone-seeking radionuclides resulted in pain responses greater than 50–60%. Treatment with a bone-seeking radiopharmaceutical is an effective therapeutic option for patients with castration-resis...
