Generally the approach is to bring a cancer into remission first (absence of symptoms) and then try to eradicate the remaining cells <unk> . Often the treatments needed to eradicate<unk>  differ from those used initially. This is an area of much research. It seems a sensible idea to aim to reduce or eradicate<unk> . What is needed is evidence on which is the best method, and how well it works. This is emerging. Treatments which specifically target<unk>  can include: * intensive conventional treatment with more drugs, or a different combination of drugs * stem cell transplant, e.g. marrow transplant. This allows more intensive chemotherapy to be given, and in addition the transplanted bone marrow may help eradicate the<unk>  * immunotherapy * monitoring the patient carefully for early signs of relapse. This is an area of active research in several countries. * treatment with monoclonal antibodies which target cancer cells * cancer vaccines
