Combination Chemotherapy in Hodgkin's Disease or Non-Hodgkin's Lymphoma Not Responding to Previous Treatment

OBJECTIVES:

• Determine the efficacy of gemcitabine, dexamethasone, and cisplatin in patients with relapsed or refractory Hodgkin's disease or aggressive non-Hodgkin's lymphoma.
• Determine the qualitative and quantitative toxicity of this regimen in these two patient populations.

OUTLINE: This is a multicenter study. Patients are stratified according to disease (Hodgkin's disease vs non-Hodgkin's lymphoma).

Patients receive oral dexamethasone on days 1-4, cisplatin IV over 1 hour on day 1, and gemcitabine IV over 30 minutes on days 1 and 8. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed at 4 weeks, 3 months, and then every 3 months thereafter.

PROJECTED ACCRUAL: A total of 44-88 patients (22-44 per stratum) will be accrued for this study within 4-10 months.

DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed Hodgkin's disease OR
• Histologically or cytologically confirmed aggressive non-Hodgkin's lymphoma (NHL) of B-cell origin (including immunoblastic, anaplastic large cell, mediastinal large B-cell, or T-cell rich B-cell NHL)

• No prior diagnosis of low-grade NHL
• No histologic evidence of transformation from indolent to aggressive histology
• Bidimensionally measurable disease that is clinically or radiologically documented

• Bone lesions not considered bidimensionally measurable
• Lymph nodes at least 1.5 cm by 1.5 cm OR
• Other non-nodal lesions at least 1 cm by 1 cm
• Recurrent or refractory to 1 prior chemotherapy regimen (excluding gemcitabine and cisplatin)
• No known CNS involvement NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
