Resistance to taxanes, such as docetaxel (Dtx) and cabazitaxel (Cbz), frequently emerges in castration resistant prostate cancer (CRPC). More importantly, NNMT-high patients were found to be non-responders to taxane-containing chemotherapy regimens. Collectively, our findings suggest that targeting NNMT and the pathways it affects, such as TGFβ, offers a viable approach for addressing taxane-resistant PC.
Despite it demonstrating efficacy in patients resistant to docetaxel and paclitaxel, two commonly used taxanes, and representing one of the second-line therapeutic options for patients with mCRPC, CBZ has limitations, including considerable side issues and reduced drug susceptibility that gradually emerge and constitute the primary cause of therapeutic failure. The resulting oxidative stress caused DNA damage and interference with mitotic spindle assembly, which induces cell cycle arrest and programmed cell death. These data indicate that AdoMet is capable of intensifying CBZ responsiveness in mCRPC cells, making the treatment more effective.
Cabazitaxel and carboplatin followed by abiraterone, together with ADT, was feasible, safe, and efficacious in patients with high-volume mCSPC, and warrants further study in larger randomized trials.
The mGPS and PNI are useful prognostic indicators for risk stratification to predict survival in patients with castration-resistant prostate cancer treated with cabazitaxel.
His treatment was started with docetaxel, receiving five cycles with good tolerance, after which he received hormonal treatment. After the infusion of 11 mL, the patient presented pharyngeal obstruction with dyspnoea, facial erythema, genital pruritus, and cervical pain that required treatment with intramuscular epinephrine. The results of the allergy study were not concordant with clinical presentation and confirmed the poor predictive value of taxane skin tests.
