Summary

Platinum-based neoadjuvant chemotherapy (NACT) followed by interval debulking surgery is a crucial treatment paradigm for advanced ovarian cancer. It can reduce tumor burden, increase the rate of R0 resection, and decrease surgical complications. The combination of paclitaxel and carboplatin is the standard NACT regimen for ovarian cancer; however, it has limitations: 1) The myelotoxicity of platinum agents may disrupt treatment continuity, and 2) Platinum-based NACT often induces the earlier development of platinum resistance. Therefore, there is a need to explore novel regimens that, while maintaining therapeutic efficacy, can reduce drug exposure and toxicity, delay platinum exposure, and postpone the onset of platinum resistance. Previous research has revealed that PARK2 can degrade phosphorylated BCL2, thereby enhancing sensitivity to paclitaxel. We established a PARK2-based molecular classification and found that 57% of advanced ovarian cancer cases exhibit high PARK2 expression. Furthermore, ovarian cancers with high PARK2 expression are highly sensitive to paclitaxel. In these patients, a platinum-free paclitaxel regimen demonstrated superior progression-free survival compared to paclitaxel-platinum combination therapy. Based on these findings, we hypothesize that for PARK2-high advanced ovarian cancer, neoadjuvant chemotherapy with single-agent paclitaxel could reduce toxicity and delay premature platinum exposure while achieving efficacy comparable to the standard doublet regimen. To test this scientific hypothesis, our team plans to conduct an exploratory clinical study. We will enroll patients with advanced, treatment-naive, surgically unresectable, PARK2-high ovarian cancer and randomize them into two cohorts: one receiving neoadjuvant single-agent paclitaxel and the other receiving neoadjuvant paclitaxel plus carboplatin. The study aims to evaluate the efficacy and safety of single-agent paclitaxel NACT in this specific patient population.
