OUTLINE: This is a dose escalation study of etoposide. Patients undergo total nodal radiotherapy twice a day on days -35 to -31, -28 to -24, and then radiotherapy boost once a day on days -21 to -17. Patients then receive etoposide IV continuously and carboplatin IV continuously on days -6 to -4 and cyclophosphamide IV over 2 hours on days -3 and -2. Autologous peripheral blood stem cells are infused on day 0. Patients who have received prior extensive radiation (at least 2000 cGy to any site) only receive chemotherapy and peripheral blood stem cell infusion. Cohorts of 4-8 patients receive escalating doses of etoposide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 1 of 4 or 2 of 8 patients experience dose limiting toxicity. Patients are followed every 1-3 months for 2 years, then every 3 months until death.
