Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialResults of the SIOP 93-01/GPOH trial and study for the treatment of patients with unilateral nonmetastatic Wilms Tumor.
The treatment of Wilms Tumor is integrated into clinical trials since the 1970's. In contrast to the National Wilms Tumor Study Group (NWTSG) the SIOP trials and studies largely focus on the issue of preoperative therapy to facilitate surgery of a shrunken tumor and to treat metastasis as early as possible. ⋯ Patients with unilateral Wilms tumor without metastasis have an excellent prognosis. The post-operative chemotherapy in stage I can be reduced to 4 weeks without worsening treatment outcome. The reduction of the tumor volume could be identified as a helpful marker for stratification of post-operative treatment. Post-chemotherapy blastemal predominant subtype of Wilms tumor has to be classified as high risk tumor. Focal anaplasia has a better prognosis than diffuse anaplasia and will be classified as intermediate risk tumor.

Multicenter Study Comparative Study Clinical Trial Controlled Clinical TrialImpact of surgery, chemotherapy and irradiation on long term outcome of intracranial malignant non-germinomatous germ cell tumors: results of the German Cooperative Trial MAKEI 89.
Malignant non-germinomatous intracranial germ cell tumors (MNGGCTs) are a heterogenous group of neoplastic lesions. Their treatment concept follows a multimodal concept that may include tumor resection for local tumor control, craniospinal irradiation to cover leptomenigeal tumor spread and chemotherapy to eliminate systemic tumor dissemination. A Platinum-based chemotherapy proven to be highly effective in testicular and non-testicular malignant germ cell tumors in adults as well as in children has also been chosen for intracranial sites. While therapeutic concepts have been thoroughly evaluated for children and adolescents with extracranial nongonadal GCTs, no such detailed long term follow-up data are available for intracranial MNGGCTs. This paper reports on the long-term outcome of 41 patients with intracranial malignant non-germinomatous GCTs enrolled into the German prospective protocol MAKEI 89. The analysis focuses on the impact of surgery, radio- and chemotherapy. ⋯ Cisplatin chemotherapy and craniospinal irradiation with tumor boost are of significant influence on long term survival in patients with MNGGCTs. The exclusion of major surgery at diagnosis using modern advances in neurosurgery or related tumor resection after neoadjuvant chemotherapy will allow a further reduction of treatment related mortality and long lasting morbidity. The analysis reveals that, given effective treatment, intracranial malignant non-germinomatous GCTs should not longer carry a poor prognosis.

ReviewHematopoietic stem cell transplantation for mucopolysaccharidoses and leukodystrophies.
The only effective treatment for selected metabolic diseases is a successful allogeneic hematopoietic stem cell transplantation (HCT). Best results with HCT are obtained when performed early in the course of the disease. Hence, timely identification and referral are critical. ⋯ Hence, UCB transplant represents an alternative to marrow HCT. Related haploidentical HCT, possibly with very high doses of CD34+ cells, may also represent an option. However, expertise has been developed in very few transplant centers and no large reports are available of its use for patients with inherited metabolic diseases.

[Out-patient palliative care of children with cancer and their families].
Pediatric palliative care is still in its beginning. Most children with life-threatening disorders succumb with incomplete symptom control under in-patient conditions. ⋯ Guidelines of pediatric palliative care are to be defined at short notice in order to ascertain autonomy and mobility of patients aiming at highest possible quality of life. The recently initiated program of integrating ambulatory and in-patient care within the regulations set forth in Germany's last health care system reform offers the chance of palliative home care of children in their terminal phase of life.
