Brief summary: A randomized controlled, multi-center, open, phase II clinical study is designed to target patients with resectable intrahepatic cholangiocarcinoma with high-risk recurrence factors which has extremely low postoperative recurrence-free survival. In this study, we aim to compare the prognosis in intrahepatic cholangiocarcinoma between Toripalimab combined with Lenvatinib and GEMOX neoadjuvant treatment and the current clinical surgical treatment (traditional group).

Detailed description: Intrahepatic cholangiocarcinoma (ICC) is a malignant tumor of biliary epithelial cells that originates from the branches of the intrahepatic bile duct at the second level and above. Its incidence accounts for about 15%-20% of primary liver malignancies, showing a gradually increasing trend. Surgical resection is currently the main method for the treatment of ICC. The data of a large number of ICC cases show that even radical resection (R0) patients have an average survival of only 18.3 months, while for palliative resection patients, the average survival is only 6.6 months, and laparotomy patients only 5.6 months. Retrospective studies reported that positive resection margins, lymph node metastasis, lymphatic vessel invasion, nerve bundle invasion, preoperative CA199\>200U/ml, multiple tumor nodules, and differentiation are the main factors affecting the survival of ICC patients after surgery. How to improve the surgical results of ICC patients, especially those with high-risk factors for postoperative recurrence, is an important way to improve the overall survival of ICC. Neoadjuvant therapy refers to some treatments taken before surgery for newly treated tumor patients who have not found distant metastasis, including chemotherapy, radiotherapy, targeted therapy, etc., to reduce tumors, reduce tumor stages, and reduce postoperative recurrence rate, prolonging survival time. Our previous study using Toripalimab combined with Lenvatinib and Gemox chemotherapy in the first-line treatment of unresectable advanced cholangiocarcinoma (NCT03951597,2020ESMO) showed that the ORR was 80% and the DCR reached 93.3%, of which 1 case was CR, 23 cases were PR, and 2 cases were successfully treated with radical resection after downstage. And the adverse reactions are controllable. These data suggest that Toripalimab combined with Lenvatinib and Gemox chemotherapy may be an ideal neoadjuvant treatment for patients with resectable intrahepatic cholangiocarcinoma with high-risk recurrence factors, needing more investigation.

Eligibility criteria: Inclusion Criteria:

* 1) Sign written informed consent 2) Male or female patients aged 18-70; 3) ECOG score 0 points, Child-Pugh rating A; 4) Clinically diagnosed as ICC as a potential entry, the neoadjuvant group must be histopathologically diagnosed as intrahepatic cholangiocarcinoma before neoadjuvant, and the traditional group must be pathologically confirmed as intrahepatic cholangiocarcinoma after surgery; 5) Resectable ICC patients with high risk factors for recurrence (tumor diameter\>5cm or imaging vascular invasion, multiple tumor nodules or hilar lymph node metastasis or preoperative CA199\>200U/ml); 6) The functional indicators of important organs meet the following requirements

  1. Neutrophils≥1.5\*109/L; platelets≥90\*109/L; hemoglobin≥9g/dl; serum albumin≥3.5g/dl;
  2. Coagulation function: International standardization (prothrombin time) ratio (INR) \<1.2;
  3. T3 and T4 do not exceed the normal upper and lower limits by 2 times;
  4. Bilirubin ≤ 1.5 times the upper limit of normal; ALT and AST ≤ 3 times the upper limit of normal;
  5. Serum creatinine ≤ 1.5 times the upper limit of normal, creatinine clearance ≥ 60ml/min; 7) The subject has at least 1 measurable liver disease (according to RECIST1.1); 8) For women who are not breastfeeding or pregnant, use contraception during treatment or 3 months after the end of treatment.

Exclusion Criteria:

* 1) Pathological diagnosis of hepatocellular carcinoma, mixed hepatocellular carcinoma and other non-biliary cell carcinoma malignant tumor components; 2) Patients who relapse after surgery, have received PD1 antibody, PDL1 antibody or CTLA4 antibody, lenvatinib, chemotherapy in the past; participated in other clinical trials 30 days before screening; 3) Past or simultaneous suffering from other malignant tumors, except for fully treated non-melanoma skin cancer, cervical carcinoma in situ and thyroid papillary carcinoma; 4) Active tuberculosis infection. Patients with active tuberculosis infection within 1 year before enrollment; a history of active tuberculosis infection more than 1 year before enrollment, no formal anti-tuberculosis treatment or tuberculosis is still active; 5) Suffer from active, known or suspected autoimmune diseases. Subjects with hypothyroidism who only need hormone replacement therapy and skin diseases without systemic therapy can be selected; 6) Past interstitial lung disease, or (non-infectious) pneumonia and need oral or intravenous steroid therapy; 7) Long-term use of systemic hormones (dose equivalent to \>10mg prednisone/day) or any other form of immunosuppressive therapy is required. Subjects using inhaled or topical corticosteroids can be selected; 8) Active infections that require systemic treatment; 9) Human immunodeficiency virus (HIV, HIV1/2 antibody) positive; 10) A history of psychotropic drug abuse, alcohol or drug abuse; 11) Significant clinically significant bleeding symptoms or a clear tendency to appear within 3 months before enrollment; 12) Suspected of being allergic to study drugs; 13) Suffer from hypertension, and cannot be well controlled by antihypertensive medication (systolic blood pressure ≥140mmHg or diastolic blood pressure ≥90mmHg); 14) After antiviral therapy, HBvDNA\>104 copies/ml, HCV RNA\>1000; 15) Accompanied by ascites, hepatic encephalopathy, Gilbert syndrome, sclerosing cholangitis, etc. Combined with insufficiency of other organs, it is expected that they cannot accept general anesthesia or hepatectomy; 16) Other factors judged by the investigator that may affect the safety of the subject or the compliance of the trial. Such as serious illnesses (including mental illness) that require combined treatment, serious laboratory abnormalities, or other family or social factors.
