The immune system can be harnessed to fight cancer by active (stimulating the patient's intrinsic immune response to cancer) and by passive (transfer of active humoral or cellular immunity) immunotherapy. While for each strategy proof-of-principle was provided, clinical benefit was limited likely due to malfunction of lymphocytes. Increasing knowledge of both the mechanism of vaccination through dendritic cells (DCs) and the potency of a subset of natural killer T lymphocytes termed cytokine-induced killer (CIK) cells led to new strategies through combining adoptive and passive immunotherapy. This review summarizes most recent clinical trials indicating that CIK cells can substantially enhance the effect of tumor vaccines and discusses the potential therapeutic benefit in the long-term control of tumor progression.  相似文献

Background

An upper limb arteriovenous (AV) fistula is the access of choice for haemodialysis (HD). There have been few reports of saphenofemoral AV fistulas (SFAVF) over the last 10-20 years because of previous suggestions of poor patencies and needling difficulties. Here, we describe our clinical experience with SFAVF.

Methods

SFAVFs were evaluated using the following variables: immediate results, early and late complications, intraoperative and postoperative complications (up to day 30), efficiency of the fistula after the onset of needling and complications associated to its use.

Results

Fifty-six SFAVF fistulas were created in 48 patients. Eight patients had two fistulas: 8 patent (16%), 10 transplanted (20%), 12 deaths (24%), 1 low flow (2%) and 20 thrombosis (39%) (first two months of preparation). One patient had severe hypotension during surgery, which caused thrombosis of the fistula, which was successfully thrombectomised, four thrombosed fistulae were successfully thrombectomised and revised on the first postoperative day. After 59 months of follow-up, primary patency was 44%.

Conclusion

SFAVF is an adequate alternative for patients without the possibility for other access in the upper limbs, allowing efficient dialysis with good long-term patency with a low complication rate.  相似文献
