Eligibility Criteria
-----------------
Inclusion Criteria: Age is 18≥years ≤70 years . ECOG body State is 0 1 score. The estimated survival period are greater than 3 months . Histologic or cytological diagnosis of advanced refractory tumors that are ineffective or without standard treatment by standard multi-line therapy. The definition of treatment invalidity: progression of disease after multiple line therapy. With the relevant qualification agencies NGS (second generation sequencing) report, and the molecular Oncology Expert Committee identified TP53 as the main harmful mutation. The patient has at least one measurable lesion that can be assessed by CT or MRI (RECIST 1.1). Previous treatment of any anti-tumor therapy (including radiotherapy, chemotherapy, hormone therapy, surgery, or molecular targeting therapy) ended with the Thou Yan ≥4 weeks (to the first medication) in this trial. Urine routine display urine protein <2+, if urine protein qualitative ≥2+, should accept 24 hour urine protein quantitative detection, ≤ 1g can be entered into a group. Good organ function level ( no blood transfusion, no use of G-CSF in the first 7 days of screening ; no drug correction;7 days without loss ALB):ANC≥ 1.5x109/L;WBC≥ 3x109 /L;PLT≥80x109/L ;Hb≥90g/l; TBIL≤1.5xULN;ALT and AST≤2.5xULN; ALB≥29g/l ;BUN and Cr ≤1. 5xULN ;LVEF ≥50%;Fridericia method to correct QT Inter-period (QTcF ) Male <450 ms , Women <470 ms . Women of childbearing age are required to take effective contraceptive measures at least 8 weeks after taking part in the study and after the last drug delivery . Can follow the test plan according to the judgment of the investigator. Volunteer to participate in this clinical trial, have the ability to understand the research requirements, can give written informed consent. Exclusion Criteria: Anticancer drugs, including Fluzoparib that used or were using PARP as a target. Antineoplastic agents used or using VEGFR targets, including Apatinib. As a participant in the clinical trial, and the signing of the informed consent of the last clinical trial at the end of the interval of less than days. Has a blood system-related tumor. Receive any anti-tumor treatment (including radiotherapy, chemotherapy, hormone therapy, surgery or molecular targeting therapy) within 4 weeks before delivery; Double phosphate drug treatment was received in the first 4 weeks of the drug delivery; There is a CTCAE grade II toxicity caused by previous treatment. Hypertension is not controlled (systolic pressure is greater than 150mmHg, or diastolic pressure is greater than 90 mmHg); or a history of congestive heart failure (American Heart Association heart function grade ≥2 Level). Clinically significant heart disease, including but not limited to: congestive heart failure, symptomatic coronary artery disease, arrhythmia, myocardial infarction, QTc period ≥470ms. Intestinal obstruction or CTCAE 3 or 4 upper digestive tract bleeding in the first 4 weeks before the drug delivery. Inability to swallow, inflammatory bowel disease or uncontrollable nausea, vomiting, diarrhea or other gastrointestinal disorders that seriously affect drug use and absorption. The tumor metastasis of central nervous system was diagnosed by the researchers. A history of severe venous thrombosis or pulmonary embolism. There is a third interstitial fluid (such as large pleural effusion and ascites) that cannot be controlled by drainage or other means. There is still an electrolyte disorder that cannot be corrected when the group is given a drug. In the first 7 days before the group received a strong CYP3A4 inhibitor treatment, or in the first day of the group received a strong effect CYP3A4 Inducer therapy. Active HBV, HCV infection (HBV copy number ≥104 copies/ml, the number of copies of HCV virus ≥103 copies /ml). There is a history of immune deficiency, including HIV testing positive, or other acquired, congenital immunodeficiency disease, or a history of organ transplantation. Pregnancy, breast-feeding female patients. In patients with bone metastases, palliative radiotherapy (radiotherapy area,5% bone marrow region) was received within 4 weeks before the group's entry. According to the researchers ' judgment, there are serious, uncontrollable risks to patients ' safety, or associated diseases (such as severe diabetes, thyroid disease, infection, spinal cord compression, superior vena cava syndrome, neurological or psychiatric disorders) that affect the patient's completion of the study.
