Clinical role of interleukin-2 in the surgical treatment of liver metastasis due to colon adenocarcinoma

TL;DRAbstract

The surgical treatment of liver metastasis due to colorectal cancer can substantially modify the natural history of the disease, mainly when it is associated with effective medical treatment. Chemotherapy, via systemic or locoregional (intrahepatic) administration, has 2 possible objectives: as adjuvant treatment, to prevent or delay disease recurrence; as neo-adjuvant treatment, mainly interesting for the surgeon, to allow resective surgery in responding patients previously considered not-operable. Unfortunately, the severe immune deficiency associated with the advanced cancer negative impact on long-term outcome after any treatment (surgery, chemotherapy) is a limit for the clinical application of multidisciplinary treatments. Aim of this study is to review the possible different approaches to improve the clinical results, either as tumour response or overall survival, using an association of IL-2 with different chemotherapy procedures, in order to recover the locoregional and/or sys
