Prostate Cancer
Conditions
Brief summary
The project aims to verify the therapeutic effect of neoadjuvant homoharringtonine combined with androgen deprivation therapy in patients with localized high-risk/very high-risk, regional lymph node-metastatic, or metastatic prostate cancer before radical prostatectomy through clinical trials, thereby identifying an effective treatment for patients with advanced prostate cancer.
Detailed description
This study is a single-arm clinical trial, and eligible patients will be enrolled. For the enrolled patients, they will receive an intravenous infusion of homoharringtonine (1 mg) plus an intravenous infusion of 5% glucose injection (250 ml), once daily for two consecutive days. Patients with localized high-risk/very high-risk and regional lymph node-metastatic prostate cancer will receive at least one cycle of the above treatment plus continuous androgen deprivation therapy; patients with metastatic prostate cancer will receive one cycle of treatment, followed by a three-week interval before repeated medication, with the treatment repeated for a total of at least three cycles plus continuous androgen deprivation therapy. All patients will undergo radical prostatectomy within 3 weeks (±7 days) after the end of treatment.
Interventions
Intravenous infusion of 1mg homoharringtonine plus 250ml of 5% glucose injection, administered once daily for two consecutive days.
All patients will undergo radical prostatectomy within 3 weeks (±7 days) after the completion of treatment.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| pCR or MRD rate | Within three weeks after the operation |
| PSA response rate | Within one week after the completion of the last treatment cycle (each treatment cycle lasts approximately 25 days) |
| Biochemical Progression-Free Survival (bPFS) after radical prostatectomy | From the date of random grouping to the date when progression was first recorded or the date of any cause of death (whichever comes first), an assessment was conducted for a period of up to 5 years. |
Secondary
| Measure | Time frame |
|---|---|
| Safety indicator: CTCAE 5.0 Adverse Event Grading | From the date of random grouping to the date when progression was first recorded or the date of any cause of death, an assessment was conducted for a period of up to 5 years. |
| Pathological response after radical prostatectomy (including positive surgical margins, tumor size, extraprostatic extension, seminal vesicle invasion, and lymph node involvement) | Within one month after the surgery |
| Quality of life score: EORTC QLQ-C30 scale | From the date of random grouping to the date when progression was first recorded or the date of any cause of death, an assessment was conducted for a period of up to 5 years. |
| Changes in radiological TNM staging from post-neoadjuvant therapy to pre-surgery | Within one month after the surgery |
| Other progression-free survival (progression includes radiological progression, castration resistance, need for further therapeutic intervention, etc.) | From the date of random grouping to the date when progression was first recorded or the date of any cause of death (whichever comes first), an assessment was conducted for a period of up to 5 years. |
