Brief summary: This study evaluates the efficacy and safety of second-line treatment of bortezomib in advanced intrahepatic cholangiocarcinoma patients.Half of participants will receive bortezomib while the other half will receive best supporting care.

Detailed description: There's no standard second-line treatment for advanced intrahepatic cholangiocarcinoma patients.

Previous study indicated high mutation/deletion rate of PTEN gene in intrahepatic cholangiocarcinoma and poor prognosis of those patients with PTEN mutation/deletion. The investigators also found that the activity of proteasomes elevated in cholangiocarcinoma cells with PTEN mutation/deletion.

So the investigators suppose proteasomes inhibitor could improve prognosis of intrahepatic cholangiocarcinoma patients with PTEN mutation/deletion

Eligibility criteria: Inclusion Criteria:

1. Patients with a histologic or cytologic diagnosis of intrahepatic cholangiocarcinoma with stage IV;
2. Have progressed after at least 2 cycles of systematic chemotherapy therapy（gemcitabine+cisplatin/gemcitabine+oxaliplatin）;
3. The previous treatment and the present trial registration must be at least 2 weeks apart, and they must have recovered from any toxicity of a previous treatment;
4. Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1;
5. Eastern Cooperative Oncology Group performance score (ECOG): 0-2; Life expectancy of at least 12 weeks;
6. Normal liver,kidney and bone marrow function；
7. Subjects who understand and voluntarily signed a written informed consent form.

Exclusion Criteria:

1. History of other malignancy within 3 years. Patients with central nervous system metastases or brain metastasis
2. There is any contraindication to use Bortezomib
