Phase I trial of procarbazine as a 5-day continuous infusion in children with central nervous system tumors.
Seven children with previously treated brain tumors were enrolled in a phase I trial of 5-day continuous-infusion procarbazine at 360, 480, and 638 mg/m2/day. Vitamin B6 levels were monitored. Myelosuppression was moderate though occasionally delayed, and nausea and vomiting were mild. At the highest dose level, a patient experienced severe psychosis that persisted for several weeks. From that dose-limiting toxicity and the degree of myelosuppression, the recommended dose for phase II trials in children is the same as for adults, 450 mg/m2/day

Salvage chemotherapy for recurrent primary brain tumors in children.
Sixty consecutive evaluable children with recurrent primary tumors of the central nervous system were treated with a regimen of vincristine, nitrogen mustard, procarbazine, and prednisone over a 12-year period. Tumor types included medulloblastoma (19), brain-stem glioma (16), astrocytoma (13), and a miscellaneous glioma (12). Responses and sustained survivals were achieved. Responses were highly dependent on tumor type. Disease progression was halted in 73% of the children with medulloblastoma, and three have survived in complete remission for more than 10 years from the start of therapy with vincristine, nitrogen mustard, procarbazine, and prednisone. Two of four patients with anaplastic glioma, are long-term survivors. In contrast, less than one third of children with brain-stem gliomas responded. Toxicity consisted mainly of neutropenia, thrombocytopenia, infections, and rarely a procarbazine rash

NITROGEN-MUSTARD, VINCRISTINE, PROCARBAZINE, AND PREDNISONE (MOPP) IN TREATMENT OF RECURRENT BRAIN-TUMORS OF CHILDHOOD
The IASLC Lung Cancer Staging Project: A Renewed Call to Participation
Over the past two decades, the International Association for the Study of Lung Cancer (IASLC) Staging Project has been a steady source of evidence-based recommendations for the TNM classification for lung cancer published by the Union for International Cancer Control and the American Joint Committee on Cancer. The Staging and Prognostic Factors Committee of the IASLC is now issuing a call for participation in the next phase of the project, which is designed to inform the ninth edition of the TNM classification for lung cancer. Following the case recruitment model for the eighth edition database, volunteer site participants are asked to submit data on patients whose lung cancer was diagnosed between January 1, 2011, and December 31, 2019, to the project by means of a secure, electronic data capture system provided by Cancer Research And Biostatistics in Seattle, Washington. Alternatively, participants may transfer existing data sets. The continued success of the IASLC Staging Project in achieving its objectives will depend on the extent of international participation, the degree to which cases are entered directly into the electronic data capture system, and how closely externally submitted cases conform to the data elements for the project

Survival and neurologic outcome of infants with medulloblastoma treated with surgery and MOPP chemotherapy. A preliminary report.
The results of treatment of infants with medulloblastoma using surgery and chemotherapy, without the use of radiation therapy, are reported. Both survival and outcome, in terms of growth, neurologic deficit, and intelligence are compared with the same parameters in children treated conventionally. Although preliminary, our results suggest that chemotherapy combined with surgery is a valid option for the treatment of infants with this type of neoplasm
