Quadruplet Therapy in De Novo High-Volume Mixed Neuroendocrine Prostate Cancer Using 177Lu-PSMA: A Case Report
We present a case of de novo high-volume metastatic prostate cancer with high PSMA expression, partially PSMA-negative, using quadruplet therapy (PROMISE ver. 2 miTNM; miT4N2M1aM1b(dmi) PRIMARY score: 5, PSMA-expression score: 0-3). Because of our patient's partial PSMA negativity and after a multidisciplinary tumor board discussion, we decided to use a modified protocol involving doublet hormonal therapy along with 177Lu-PSMA and radiation therapy to address the PSMA-negative disease. The patient responded well to this treatment, but recurrence was ultimately inevitable. This case represents a typical example of mixed neuroendocrine prostate carcinoma and highlights its resistant phenotype in response to quadruplet therapy.PMID:38306385 | DOI:10.1097/RLU.0000000000005046
