[Is it useful to correct the immunological deficit in cancer patients? And with what modality?]

A certain degree of immunodepression appears to be present in some neoplastic patients. Many factors such as age and nutritional and hormonal state (particularly thymic factors and locally-acting hormones like prostaglandins of E series) are involved in this phenomenon. The literature shows that all these factors are very important in neoplastic processes and might strikingly contribute also to the extent of immunodepression observed in neoplastic patients. Moreover, the HLA genotype seems to effect the efficiency of the antineoplastic treatments. The authors think that immunodepression in neoplastic patients might be improved by immunomodulators such as zinc ions, thymic hormones and, possibly, inhibitors of prostaglandins of E series.
