Cancer Therapies And Its Effects On Patients

Introduction
Despite the numerous advances in recent years, many cancer therapies have retained a focus on cytotoxic chemotherapy or radiotherapy as the main course of treatment in patients with various types of maligancies. This approach is however unspecific in its mechanism, and effects its cytotoxic mechanism on healthy patient cells as well as cancer cells, causing a variety of secondary health problems and side effects in the patients, the most obvious and commonly observed being hair loss and an abnormal Full Blood Count profile (thrombocytopenia, for example).
It is therefore unsurprising that an increasing amount of research is being carried out on immunological approaches to cancer treatment, which is inherently more specific, targeting malignant neoplastic cells which may display a specific stress marker, opposed to general cellular destruction, and which carry a significantly lower risk of short and long-term secondary health risks and side effects.
A particularly promising branch of cancer immunotherapy is that of gamma-delta T cells, which, in a variety of recent studies, have shown to exert an anti-tumour mode of action onto transformed, malignant cells.
In addition, the cell transfer is autologous, therefore the risk of cross-reactions and tissue rejections associated with allogenic transfers are not a factor in this treatment, which is of further benefit to both the researchers and the patients.

It is hoped that the use of gamma-delta T cells will
