RATIONALE: Drugs used in chemotherapy, such as dexamethasone, cisplatin, gemcitabine, and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with autologous stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Giving rituximab as maintenance therapy after stem cell transplantation may kill any remaining cancer cells. It is not yet known which salvage chemotherapy regimen is more effective before autologous stem cell transplantation in treating relapsed or refractory non-Hodgkin's lymphoma.

PURPOSE: This randomized phase III trial is studying salvage chemotherapy using dexamethasone, cisplatin, and gemcitabine to see how well it works compared to dexamethasone, cisplatin, and cytarabine given before autologous stem cell transplantation in treating patients with relapsed or refractory aggressive non-Hodgkin's lymphoma. This trial also is studying giving rituximab as maintenance therapy to see how well it works compared to no further therapy after stem cell transplantation. Rituximab was added to both salvage treatment arms for CD20+ patients in a protocol amendment in 2005.

Official Title: A Phase III Study Of Gemcitabine, Dexamethasone, And Cisplatin Compared To Dexamethasone, Cytarabine, And Cisplatin Plus/Minus Rituximab [(R)-GDP vs (R)-DHAP] As Salvage Chemotherapy For Patients With Relapsed Or Refractory Aggressive Histology Non-Hodgkin's Lymphoma Prior To Autologous Stem Cell Transplant And Followed By Maintenance Rituximab Versus Observation

Primary Outcome Measures:
  • Response Rate of Patients After 2 Courses of Chemotherapy [ Time Frame: After 2 cycle of treatment ]
    The overall response rate by arm is calculated as total number of responders (CR + CRu + PR) / (all patients in the ITT analysis population).

  • Transplantation Rate of Patients After 2 Courses of Chemotherapy [ Time Frame: During period 1 (salvage chemotherapy) ]
    Transplantation rate is defined as the number of patients who respond sufficiently to protocol salvage chemotherapy to be planned for transplantation minus those who do not meet the endpoint of successful transplantation, divided by the number of all randomized patients

  • Event-free Survival of Patients on Maintenance Randomization (Period 2) [ Time Frame: during the period 2 (up to10 years) ]
    Number of patients who develop EFS event during maintenance randomization (period 2)

Secondary Outcome Measures:
  • Mobilization Rate of Patients on Treatment Arm I Assessed by CD34 Count After 2 Courses of Therapy and Stem Cell Harvesting [ Time Frame: 10 years ]
  • Toxicity Assessed by NCI CTC v2.0 for 2 Years in Patients on Treatment Arm II [ Time Frame: 10 years ]

Enrollment: 619
Study Start Date: August 2003
Estimated Study Completion Date: December 2017
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
