Brief summary: Anlotinib is a multi-target receptor tyrosine kinase inhibitor. It can inhibit the angiogenesis related kinase, such as Vascular Endothelial Growth Factor Receptor (VEGFR), Fibroblast Growth Factor Receptor(FGFR), Platelet-Derived Growth Factor Receptor(PDGFR), and tumor cell proliferation related kinase c-Kit kinase. Anlotinib is an efficient second line therapeutic agent in treatment for metastatic soft tissue sarcoma which has been approved in clinical trials (ALTER-0203). Therefore, this study evaluates the safety and efficacy of anlotinib as maintenance treatment of disease control in advanced soft tissue sarcoma.

Detailed description: 48 cases are preliminarily expected to be included. This study evaluating the safety and efficacy of anlotinib as a maintenance treatment after first-line anthracycline-based chemotherapy in advanced soft tissue sarcoma.

All those participants need to sign informed consent forms for data collection and be used for research purpose before inclusion. Participants remained PR/SD after ≥4 cycles of anthracyclines could be enrolled.

48 subjects with advanced soft tissue sarcoma will receive anlotinib at a dose of 12 mg once daily (day1-14 PO) in 21-day cycles until disease progression (defined by RECIST version 1.1) or unacceptable toxicity.

Eligibility criteria: Inclusion Criteria:

* Signed and dated informed consent form prior to patient entry;
* 18-70 years , regardless of gender；ECOG :0-2;Expected Survival Time: Over 3 months;
* Subjects with pathologically confirmed advanced synovial sarcoma, leiomyosarcoma, liposarcoma, angiosarcoma, etc. (except malignant peripheral nerve sheath tumor, undifferentiated sarcoma, rhabdomyosarcoma, chondrosarcoma, osteosarcoma, dermato- fibrosarcoma protuberans, gastrointestinal stromal tumor, ewing's sarcoma/primitive neuroectodermal tumor, inflammatory myofibroblastic tumor, and malignant mesothelioma);
* Evaluable disease by imaging or physical exam or measurable disease defined as at least one lesion that can be accurately measured according to RECIST version 1.1.
* PR/SD patients after ≥4 cycles anthracyclines treatment .
* Main organs function is normal.(normal main organs function as defined below: Hemoglobin (Hb) ≥ 80g / L, Neutrophils (ANC) ≥ 1.5 × 109 / L, Platelet count (PLT) ≥ 80 × 109 / L, Serum creatinine (Cr) ≤ 1.5 × normal upper limit (ULN) or creatinine clearance (CCr) ≥ 60ml / min, Blood urea nitrogen (BUN) ≤ 2.5 × normal upper limit (ULN); Total bilirubin (TB) ≤ 1.5 × ULN; Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN; If accompanied by liver metastases, ALT and AST ≤ 5 × ULN Albumin (ALB) ≥ 25 g/L. Doppler ultrasound assessment: left ventricular ejection fraction (LVEF) ≥ normal low limit (50%).)
* The woman patients of childbearing age who must agree to take contraceptive methods (e.g. intrauterine device, contraceptive pill or condom) during the research and within another 6 months after it; who are not in the lactation period and examined as negative in blood serum test or urine pregnancy test within 7 days before the research; The man patients who must agree to take contraceptive methods during the research and within another 6 months after it.

Exclusion Criteria:

* Prior treatment with anlotinib.
* A history of other malignancy ≤ 5 years previous.
* Systemic anti-tumor therapy, including cytotoxic therapy, signal transduction inhibitors, and immunotherapy, is planned for the first 4 weeks prior to enrollment or during the study. Radiation radiotherapy (EF-RT) was performed within 4 weeks prior to enrollment.
* Unmitigated toxic reactions above grade 1 of CTC AE due to any previous treatment, excluding alopecia.
* Symptoms that affect oral medication and can not be controlled through proper treatment. (such as inability to swallow, chronic diarrhoea and intestinal obstruction, etc.)
* With pleural effusion or ascites, cause respiratory syndrome. (\> CTC AE grade 2 dyspnea \[grade 2 dyspnea refers to shortness of breath during a small amount of activity; affecting instrumental activities of daily life\])
* Symptoms of brain metastases cannot be controlled and treated within less than 2 months.
* Thyroid dysfunction after best support treatment.
* With severe and failed to controlled diseases. (including:1)Uncontrollable hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, despite optimal drug treatment).2)Arrhythmias with grade II and above myocardial ischemia or myocardial infarction, poor control (including corrected QT interval(QTc) men ≥ 450 ms, women ≥ 470 ms) and ≥ 2 congestive heart failure (New York Heart Association ( NYHA) rating).3)Poor control of diabetes (fasting blood glucose \> 10mmol / L).4)Active or uncontrolled serious infection (≥ Common Terminology Criteria for Adverse Event(CTC AE) grade 2 infection);5)Patients with active hepatitis B or hepatitis C (hepatitis B: HBsAg-positive and hepatitis B virus(HBV) DNA ≥ 500 IU/mL; hepatitis C: hepatitis C virus(HCV) RNA-positive and abnormal liver function), or active infection requiring antimicrobial treatment (eg Treated with antibacterial drugs, antiviral drugs, antifungal drugs);6)renal insufficiency: urine routine indicates urinary protein ≥ ++, or confirmed 24-hour urine protein ≥ 1.0 g;7)Patients with seizures and need treatment.)
* Accepted surgical treatment, incision biopsy or significant traumatic injury within 28 days before grouping.
* The investigator judged that during the follow-up study, the tumor is very likely to invade the important blood vessels and cause fatal hemorrhage, or the formation of tumor thrombosis with large veins (iliac vessels, inferior vena cava, pulmonary veins, superior vena cava)
* Any major unhealed wound, ulcer, or fracture occurred in a patient who had undergone major surgery or trauma within 4 weeks and/or had any bleeding or bleeding episodes which the degree is bigger than CTCAE 3 grade within 4 weeks prior to enrollment.
* Arteriovenous thrombosis events occurred within 6 months.
* History of psychotropic substance abuse who are unable to quit or have a mental disorder.
* Participated in other anti-tumor clinical trials within 4 weeks.
* The investigator believes that there are any conditions that may damage the subject or result in the subject not being able to meet or perform the research request.
