研究目的: |
卵巢癌已成为妇科恶性肿瘤的主要死亡原因。约70%的OC患者确诊于疾病晚期(FIGO Ⅲ或Ⅳ期),其五年生存率不到30%。手术后化疗是OC的主要治疗方式,铂类联合紫杉类化疗的有效率达80%以上,其中一半以上能做到肿瘤完全缓解,但即便如此仍有50%~70%患者复发,且复发患者中铂耐药占大多数。由于初次诊断晚且对于耐药复发卵巢癌缺乏有效的治疗,卵巢的总体预后较差。我们团队前期研究采用卵巢癌疾病模型,首次发现酪氨酸分解代谢显著增强化疗效果,并揭示酪氨酸代谢产物富马酸,通过抑制跨损伤 DNA 合成,促进基因毒性化疗药物敏感性的分子机制,为临床上应用膳食酪氨酸改善化疗效果提供了重要理论依据。本研究旨在基于我们前期发现(即酪氨酸代谢可增强化疗敏感性)的理论基础,在真实的临床人群中,通过前瞻性观察探索化疗期间膳食酪氨酸的自然摄入水平与复发卵巢癌患者生存预后之间的关联性。 |

Objectives of Study: |
Ovarian cancer has become the leading cause of death among gynecological malignancies. Approximately 70% of OC patients are diagnosed in the advanced stage of the disease (FIGO stage III or IV), and their five-year survival rate is less than 30%. Postoperative chemotherapy is the main treatment for OC. The effective rate of platinum-based combined with taxane-based chemotherapy is over 80%, and more than half of them can achieve complete tumor remission. However, even so, 50% to 70% of patients still relapse, and the majority of relapsed patients are platinum-resistant. Due to the late initial diagnosis and the lack of effective treatment for drug-resistant and recurrent ovarian cancer, the overall prognosis of the ovaries is poor. Our team's previous research used an ovarian cancer disease model and for the first time discovered that tyrosine catabolism significantly enhances the efficacy of chemotherapy. We also revealed the molecular mechanism by which the tyrosine metabolite fumaric acid promotes the sensitivity of genotoxic chemotherapy drugs by inhibiting cross-damage DNA synthesis. This provides an important theoretical basis for the clinical application of dietary tyrosine to improve the efficacy of chemotherapy. Therefore, this study aims to build upon our previous findings (namely, that tyrosine metabolism can enhance chemotherapy sensitivity) and, based on this theoretical foundation, conduct a prospective observation in real clinical populations to explore the association between the natural intake level of dietary tyrosine during chemotherapy and the survival prognosis of patients with recurrent ovarian cancer. |
