A variety of immunostimulants can affect the growth of established syngeneic tumor transplants and autochthonous neoplasms. These immunostimulants include viable organisms, nonviable bacterial products, and chemically defined compounds (TABLE 1 ) . Viruses and bacterial endotoxins can also inhibit tumor growth, but it is not clear that they are primarily immunostimulants, and consideration of their complex mode of action is beyond the scope of this review. Over the last decade, there have been numerous attempts to cure established syngeneic or autochthonous tumors in guinea pigs, mice, rats, hamsters, cows, and primates by use of immunostimulants, alone or in combination with tumor cell vaccines. A substantial literature has accumulated, and progress has been made toward defining conditions for optimal immunotherapy. At present, however, our ability to control tumor growth with active immunotherapy is modest. With a few significant exceptions, systemic immunotherapy has failed to produce complete regression of palpable neoplasms. Local immunotherapy with Bacillus Calmette-Gukrin (BCG) and the corynebacteria can cure small tumor nodules and stimulate systemic tumor-specific immunity, but this approach depends on the introduction of an immunostimulant in close proximity to tumor cells, which is often difficult to achieve in clinical practice. Even when direct contact can be assured, some tumor lines have proven resistant to local immunotherapy. Given these limitations, it seems important to examine critically those systems where immunostimulants have been effective in order to identify factors that are likely to contribute to successful immunotherapy in human cancer.
