Evaluation of the Sensitivity to Different Chemotherapy Regimens in Platinum-Partial Sensitive Recurrent Ovarian Cancer

Evaluation of the Sensitivity to Different Chemotherapy Regimens in Platinum-Partial Sensitive Recurrent Ovarian Cancer Based on 11 Gene Tests of Homologous Recombination Pathway

Multicenter, prospective, randomized studies.Evaluation of the sensitivity to different chemotherapy regimens in platinum-partial sensitive recurrent ovarian cancer based on 11 gene tests of homologous recombination pathway.

Patients meeting the following inclusion criteria were randomly divided into two groups in a 1:1 ratio: paclitaxel/platinum chemotherapy group (TP) and Doxorubicin Hydrochloride Liposome Injection/platinum chemotherapy group (PP) (the specific chemotherapy regimens are as follows.Chemotherapy to tumor progression or adverse reactions can not be tolerated, effective chemotherapy patients with a maximum of 6 cycles of chemotherapy.The primary endpoint was progression-free survival (PFS), and the secondary endpoints were safety and overall survival.Also USES the next-generation sequencing (NGS) method to detect patients with recurrence after tumor tissues (including chest, ascites, homologous recombination pathway in the tumor tissue and peripheral blood ctDNA 11 genetic mutations, rearrangement, and so on and so forth, whether patients with analysing the homologous recombination pathways for paclitaxel/platinum chemotherapy or Doxorubicin Hydrochloride Liposome Injection/platinum chemotherapy has different sensitivity.

Inclusion Criteria:

1. age: 18-75 years old
2. PS score: ECOG 0 ~ 2
3. histopathologically confirmed primary high-grade serous adenocarcinoma or high-grade endometrioid adenocarcinoma of the ovary, fallopian tube or peritoneum;
4. the time interval between this recurrence and the last chemotherapy was 6-12 months;
5. evaluate the ability of bone marrow, liver, kidney, heart and other important organ functions to withstand chemotherapy;
6. expected survival over 3 months;
7. sign the informed consent.

Exclusion Criteria:

1. brain metastasis or the presence of symptoms caused by brain metastasis;
2. serious complications;
3. acute inflammatory reaction;
4. other tumors;
5. a history of allergy to paclitaxel or polyropyridone liposomes;
