RESUMO
BACKGROUND: The recent advances in the psychooncological and psychoneuroimmunological investigations of cancer patients has allowed the rediscovery of the importance of spiritual faith in influencing the clinical course of neoplastic disease, not only in terms of supportive care but also as a potential prognostic variable. MATERIALS AND METHODS: Clinical criteria were worked out to explore the existence of a real status of faith, in an attempt to correlate the degree of faith with the clinical response to chemotherapy, consisting of cisplatin plus gemcitabine, and the overall survival time in a group of 50 metastatic nonsmall cell lung cancer patients. RESULTS: The tumor response rate achieved in patients with a high degree of faith was significantly higher than in the other group of patients. Moreover, the mean postchemotherapeutic lymphocyte number was significantly higher in the patients with evident spiritual faith than in the other patients. Finally, the percent age of 3-year survival observed in the patients with a high degree of faith was significantly higher than that in the patients with a low faith score. CONCLUSION: This preliminary study suggests that spiritual faith may positively influence the efficacy of chemotherapy and the clinical course of neoplastic disease, at least in lung cancer, by improving the lymphocyte-mediated anticancer immune response.

BACKGROUND: The prognosis of cancer and the efficacy of the various anticancer therapies depend not only on tumor characteristics, but also on the endocrine and immune status of patients. Moreover, studies have shown that the clinical course of the neoplastic disease is also influenced by the psychospiritual status of patients. It is thus probable that the influence of psychospirituality on tumor growth may be mediated by the immunoneuroendocrine system, as demonstrated by the recent advances in psychoneuroendocrinological research. However, at present there are only few data on the possible link between the psychospiritual status and immunoendocrine functions of cancer patients. This study was carried out to investigate the relationships existing among the psychospiritual profile, cortisol rhythm and lymphocyte number before and after chemotherapy, and the efficacy of chemotherapy itself in advanced cancer patients. PATIENTS AND METHODS: The study included 30 consecutive metastatic non-small cell lung cancer patients under chemotherapeutic treatment with cisplatin plus gemcitabine. The psychobiological investigations consisted of lymphocyte count, cortisol circadian rhythm, psychological profile using Rorschach test, and spiritual score, as assessed by a specific clinical test for spirituality. The control group consisted of 100 healthy volunteers. The patients who achieved a tumor regression, showed a significantly higher pre-treatment lymphocyte count and significantly lower alteration of the cortisol rhythm with respect to those who had no benefit from chemotherapy. Moreover, the lymphocyte mean number increased during chemotherapy in responder patients, whereas it progressively diminished in those who had disease progression. Lymphocytopenia and alterations of the cortisol rhythm prior to chemotherapy were associated with a loss of the psychosexual identity according the Rorschach test. Moreover, the mean spiritual score was lower in patients than in controls, although the difference was not significant. Finally, a low spiritual score prior to therapy was associated with a higher frequency of lymphocytopenia and cortisol rhythm alteration, as well as with a lower efficacy of chemotherapy itself. CONCLUSION: This preliminary study would suggest that the psychospiritual status of cancer patients may influence the efficacy of chemotherapy through the immunoneuroendocrine system.

AIMS: Studies dealing with the increased tendency to stone formation noted in cystic fibrosis, focus on enteric hyperoxaluria. It is well recognized, however, that low urine volume, hypocitraturia and perhaps even hypercalciuria are further risk factors for stone formation. METHODS: Nineteen patients with cystic fibrosis (14 boys and 5 girls, aged 10-23, median 15 years) underwent a standard protocol for metabolic evaluation of the lithogenic tendency. In 10 patients, the study was repeated after treatment with recombinant human growth hormone 43 microgram/kg body weight daily for 12 months. RESULTS: The metabolic evaluation disclosed low urine output in 12, hyperoxaluria in 8 and hypocitraturia in 9 of the 19 cystic fibrosis patients. The mentioned parameters were not influenced by treatment with recombinant human growth hormone. CONCLUSION: The report indicates that in cystic fibrosis low urine volume, hypocitraturia and hyperoxaluria act in concert and contribute to the likelihood of stone formation. This tendency is not modified by treatment with recombinant human growth hormone.
