Article Abstract
Objective: To evaluate the safety and efficiency of using abiraterone and prednisone in the treatment of patient with metastatic castration resistant prostate cancer (mCRPC) no prior chemotherapy.
Methods: Three mCRPC no prior chemotherapy patients accepted abiraterone and prednisone treatment. The clinical data were analyzed retrospectively and the safety and efficiency of this treatment option were discussed. The Gleason scores of the three mCRPC patients were 5, 9, and 9. The clinical stages were T3aNxM0, T3aNxM1b, and T3aNxM1b. The patients received abiraterone 1 000 mg daily and prednisone 5 mg twice daily and androgen deprivation therapy in the treatment. Their blood pressure, complete blood count, prostate specific antigen (PSA), biochemical parameters, whole body CT scan and bone scan were done regularly to monitor the progression of the diseases.
Results: In this study, the general condition improved in two patients. Two of the three patients experienced decrease of PSA and no progression. One patient experienced disease progression. Generally, abiraterone and prednisone resulted in prolonged radiographic progression-free survival and delayed in PSA progression in mCRPC no prior chemotherapy. There were no severe side effects, such as hypokalemia, hypertension, and water-sodium retention. The patient's tolerance was good.
Conclusion: Abiraterone and prednisone are safe and can improve mCRPC no prior chemotherapy patient's life quality and may prolong the overall survival.

Purpose: Limited data is available assessing sequencing of antibody drug conjugates (ADCs) in patients with hormone receptor-positive (HR +), human epidermal growth factor 2 (HER2)-negative, HER2-low, and triple-negative metastatic breast cancer (MBC), including patients with brain metastases (BrM) or leptomeningeal disease (LMD). This study assesses the efficacy and safety of sequential sacituzumab govitecan (SG) and trastuzumab deruxtecan (T-DXd) in MBC and impact on chemotherapy (CTX).
Methods: This is a single-center, retrospective, cohort study in adult patients with HR + , HER2-negative, or low MBC who received T-DXd and/or SG.

Glioblastoma is the most aggressive and malignant tumor of the central nervous system. Current treatment options, including surgical excision, radiotherapy, and chemotherapy, have Limited efficacy, with a median survival rate of approximately 15 months. To develop novel therapeutics, it is crucial to understand the underlying molecular mechanisms driving glioblastoma.

Pancreatic cancer is a highly aggressive malignancy with a dismal prognosis, characterized by a complex tumor microenvironment that promotes immunosuppression and limits the efficacy of immune checkpoint blockade (ICB) therapy. Fibroblast activation protein (FAP) is overexpressed in the tumor stroma and represents a promising target for therapeutic intervention. Here, we developed a novel antibody-drug conjugate (ADC) targeting FAP, and investigated its anti-tumor activity and ability to enhance ICB efficacy in pancreatic cancer.

With the approval of the antibody-drug conjugate enfortumab vedotin (EV), NECTIN4 has emerged as a bona fide therapeutic target in urothelial carcinoma (UC). Here, we report the development of a NECTIN4-directed chimeric antigen receptor (CAR) T cell, which exhibits reactivity across cells expressing a range of endogenous NECTIN4, with enhanced activity in high expressors. We demonstrate that the PPARγ pathway, critical for luminal differentiation, transcriptionally controls NECTIN4, and that the PPARγ agonist rosiglitazone primes and augments NECTIN4 expression, thereby increasing sensitivity to NECTIN4-CAR T cell-mediated killing.
