In the past several years, interest in the immunophysiological role of the pineal gland and melatonin has grown to the extent that now their immunoregulatory role is widely recognized. Melatonin has immunoenhancing properties and it is able to counteract the immunodepression induced by acute stress, drug treatment (i.e., anticancer drugs), and viral infections. Here we review the therapeutic efficacy of melatonin alone or in combination with interleukin-2 (IL-2) in cancer patients who did not respond to standard anticancer chemotherapies and/or refused any aggressive treatment. In this review, we summarize a series of reports from 1986 through 1994 in which patients affected by metastatic solid tumors, metastatic non-small-cell lung cancer, advanced solid neoplasms, myelodysplastic syndrome, hepatocellular carcinoma, and advanced endocrine tumors were studied. The conclusion drawn from these studies is that melatonin protects against IL-2 and synergizes with the IL-2 anticancer action. This combined strategy represents a well tolerated intervention to control tumor growth. In most cases performance status and quality of life seem improved.

In this study, the authors investigated the relationship between autobiographical memory and the onset and maintenance of distressing memories following cancer. In Study 1, participants recently diagnosed with head, neck, or lung cancer were assessed for acute stress disorder (ASD). Participants with ASD reported fewer specific memories than did participants without ASD. In Study 2, the same participants were assessed 6 months later for autobiographical memory and cancer-related posttraumatic stress disorder (PTSD). Deficits in the retrieval of specific memories in Study 1 were not predictive of subsequent PTSD. Increased hopelessness during the 6 months was associated with a decline in the retrieval of positive memories and an increase in the retrieval of negative memories. These findings accord with propositions that retrieval of distressing memories is guided by current self-image and attitude toward one's future.
