A status report on the management of solid tumours

Progressive improvements in the management of certain paediatric and haematological malignancies have provided guidelines for the current approaches to the management of the more common solid tumours of adults. These include precise histopathological grading; comprehensive evaluation of extent of disease; staging classifications accurately correlated with prognosis and progressive evaluation of available therapeutic modalities for all stages of disease in an attempt to define the best combination of local and systemic forms of therapy. Breast cancer is reviewed in detail as an example of the more responsive tumours where screening programs; improvements in pathological and clinical staging and the introduction of systemic chemotherapy together with optimal use of other methods of treatment for the various stages of disease gives hope for a significant improvement in long term survival statistics. Lung cancer has also been reviewed as an example of the more resistant types of cancer where screening programmes and current therapy including the use of combination chemotherapy have given minor encouragement but not had a definite influence on long term survival. Some further gains may still be achieved with currently available techniques but major improvements will probably require the development of better therapeutic tools including radiotherapy with high linear energy transfer particles; new chemotherapeutic agents and specific forms of immunotherapy. It is also quite possible that completely different forms of therapy for these resistant tumours will be necessary to reach the desired goal of long term improvements in survival.
