6. Performance status 0-1
7. ASA ≤ 3
8. ≥ 18 years of age
9. Written and orally informed consent
10. Sufficient available histological tumor material stored in biobank or obtainable by new biopsy
11. Patient acceptance of collection of blood samples for translational research and two additional biopsies during treatment

12. Adequate bone marrow function, liver function, and renal function (within 7 days prior to enrollment):

    1. Neutrophils (ANC) ≥ 1.5 x 109/l
    2. Platelet count ≥ 100 x 109/l
    3. Hemoglobin ≥ 6 mmol/l
    4. Plasma bilirubin ≤ 1.5 x ULN
    5. Plasma alanine transaminase (ALAT) < 5 x ULN
    6. Plasma creatinine ≤ 1.5 x ULN
    7. INR ≤ 1.5

Exclusion Criteria:

1. Underlying medical disease not adequately treated (e.g. poorly regulated diabetes and symptomatic cardiac disease)
2. Prior or current autoimmune disorder with risk of serious toxicity during treatment with checkpoint inhibitor
3. Acute myocardial infarction, cerebral vascular attack, transient ischemic attack or subarachnoid hemorrhage within 6 months from start of treatment

6. Positive HIV, HBV, and HCV test results (prior testing or new testing in patients at risk)
7. Active psychiatric disease or history of drug or alcohol abuse affecting participation
8. Allergy to active substance or any of the auxiliary agents, including known severe allergy to anesthetic agent, paralytic agent or any of the equipment used during treatment
9. Expected need for systemic corticosteroid or other systemic immunosuppressive drug during the course of this clinical trial. A low dose of e.g. prednisone ≤ 10 mg/day is permitted for maximally 7 consecutive days
10. Coexisting malignant disease, except non-melanoma skin cancer
