Dosimetry-based high-activity therapy with 131I-metaiodobenzylguanidine (131I-mIBG) and topotecan for the treatment of high-risk refractory neuroblastoma.

PURPOSE: Patients with high-risk neuroblastoma have an increased risk of recurrence and relapse of disease and a very poor prognosis. 131I-metaiodobenzylguanidine (131I-mIBG) in combination with topotecan as a radiosensitizer can be an effective and relatively well-tolerated agent for the treatment of refractory neuroblastoma. The aim of this retrospective study was to evaluate response and outcome of combined therapy with 131I-mIBG and topotecan. METHODS: Ten patients, between 3 and 20 years of age, were included. Nine patients had been refractory to several lines of chemotherapy and radiotherapy. One patient with a very high-risk neuroblastoma had received only induction therapy. Response was graded according to the International Neuroblastoma Staging System. RESULTS: Regarding treatment response, two patients achieved complete remission, one with relapse at 16 months, five achieved a partial remission, four showed progression at between 1 and 18 months; two showed stable disease with progression at between 1 and 5 months, and one showed progressive disease. Eight of the ten patients died with overall survival between 4 and 63 months, and two patients were still alive without disease at the time of this report: 52 and 32 months (patient had received only induction therapy). Acute and subacute adverse effects were mainly haematological, and one patient developed a differentiated thyroid cancer. CONCLUSION: In patients with high-risk refractory neuroblastoma, administration of high activities of 131I-mIBG in combination with topotecan was found to be an effective therapy, increasing overall survival and progression-free survival. Further studies including a larger number of patients and using 131I-mIBG for first-line up-front therapy are warranted.

Spiritual support for adolescent cancer patients: a survey of pediatric oncology centers in Italy and Spain.

INTRODUCTION: Spirituality is a fundamental aspect of the psychological well-being of adolescents with cancer. This study reports on a survey conducted at pediatric oncology centers in Italy and Spain to examine the situation concerning the provision of spiritual support. METHODS: An ad hoc questionnaire was distributed including multiple-choice questions on whether or not spiritual support was available; the spiritual counselor's role; how often the spiritual counselor visited the unit; and the type of training this person had received. RESULTS: A spiritual support service was available at 24 of the 26 responding centers in Italy and 34/36 in Spain. The training received by the spiritual counselor was exclusively theological in most cases (with medical or psychological training in a few cases). In both countries the spiritual counselor was mainly involved in providing religious services and support at the terminal stage of the disease or in talking with patients and families. Cooperation with caregivers was reported by 27.3% and 46.7% of the Italian and Spanish centers, respectively, while the daily presence of the chaplain on the ward was reported by 18.2% and 26.7%. CONCLUSIONS: The role of the spiritual counselor in pediatric oncology - in Italy and Spain at least - is still neither well-established nor based on standardized operating methods or training requirements. A model that implies the constant presence of a spiritual counselor in hospital wards may be proposed to provide appropriate spiritual support to adolescents with cancer.
