Despite breakthroughs in medical technology, cancer is still a difficult disease to treat without detection in early stages.  It is a refractory disease that is a primary cause of death.  Currently, standard modes of treatment consist of chemotherapy, surgical resection, targeted therapy, radiotherapy and sometimes even hormone therapy.  Although there are significant advances in each therapy area, a sufficient therapeutic effect is still beyond reach whenever monotherapy is utilized.  Combination therapy or the use of more than one treatment regimen permits a better approach that provides more enhanced results.

Each therapy approach provides benefits.  For instance, surgical resection may be curative but resection is not possible for some sites of cancer.  On the other hand, radiotherapy kills cancer cells, wherein resection may not be possible, through irradiation.  Considerably, many cancers are metastatic or advanced and cannot be managed by local therapies such as radiotherapy and surgical resection.  The alternative here would be chemotherapy.  Nonetheless, the effect of anticancer agents usually come with serious adverse reactions or side effects.  In the light of this, immune-cell therapy has been developed as a useful systemic treatment by focusing on mechanisms of immune response to cancer cells.  It is an option that widens the armamentarium in fighting cancer.  The supportive and enhancing effects of immunotherapy provides better quality of life for the cancer patient.  It has no adverse reactions in essence.  The preventive effects against recurrence have been reported when used as post-operative adjuvant therapy.  In combination therapy with chemotherapy, it further enhances quality of life and reports also show some prolongation in life.  Immunotherapy through the use of stem cells is a fresh and natural way of effectively fighting cancer.
