• Estimated life expectancy of at least 3months

• Age≥18 years

• Adequate bone marrow, liver and renal function: Hemoglobin>9.0g/dl, Absolute neutrophil count>1,500/mm3, Platelet>100,000/μl Total bilirubin<1.5 times the upper limit of normal (ULN), ALT and AST<2.5xULN (<5xULN for patients with liver involvement of their cancer), PT-INR/PTT<1.5xULN, Serum creatinine<2xULN

• Written informed consent

Exclusion Criteria:

• Dementia or significantly altered mental status that would prohibit the understanding or rendering of informed consent and compliance with the requirements of this protocol

• Patients with any severe and/or uncontrolled medical conditions such as unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction ≤6months, serious uncontrolled cardiac arrhythmia, uncontrolled hyperlipidemia, active or uncontrolled severe infection, cirrhosis, chronic or persistent active hepatitis or severely impaired lung function.

• History of HIV infection and active clinically serious infections (>grade 2 according to NCI-CTCAE vs. 4.0)

• Symptomatic metastatic brain or meningeal tumors (unless the patient is >6months from definitive therapy, has a negative imaging study within 4weeks of study entry and is clinically stable with respect to the tumor at the time of study entry)

• Patients with seizure disorders requiring medication

Patients receiving corticosteroids must be on a stable dose for ≥4weeks prior to the first dose of Everolimus. Topical or inhaled corticosteroids are permitted

• Patients with a history of another malignancy within 5years prior to study entry, except curatively treated non-melanotic skin cancer or in-situ cervical cancer skin or other solid tumors curatively treated with no evidence of disease for ≥3years. Patients with severe and/or uncontrolled concurrent medical disease that in the opinion of the investigator could cause unacceptable safety risks or compromise compliance with the protocol

• Anticancer chemotherapy or immunotherapy during the study or within 4weeks of study entry

• Radiotherapy during study or within 3weeks of start of study drug. (Palliative radiotherapy will be allowed)

• Major surgery within 4weeks of start of study
