S0350 Combination Chemotherapy in Treating Patients With Newly Diagnosed Stage II, Stage III, or Stage IV Peripheral T-Cell Non-Hodgkin's Lymphoma
RATIONALE: Drugs used in chemotherapy, such as cisplatin, etoposide, gemcitabine, and methylprednisolone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.
PURPOSE: This phase II trial is studying how well combination chemotherapy works in treating patients with newly diagnosed stage II, stage III, or stage IV T-cell non-Hodgkin's lymphoma.

- Overall survival [ Time Frame: 0-2 years ] [ Designated as safety issue: No ]Measured from date of registration to date of death due to any cause. Patients last known to be alive are censored at date of last contact
- Progression-free Survival [ Time Frame: 0-2 years ] [ Designated as safety issue: No ]Measured from date of registration to date of first observation of progressive disease or death due to any cause. Patients last known to be alive and progression-free are censored at date of last contact.
- Toxicity (Number of Patients With Grade 3 Through Grade 5 Adverse Events that are Related to Study Drug) [ Time Frame: up to 18 weeks of protocol treatment ] [ Designated as safety issue: Yes ]Adverse Events (AEs) are reported by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. For each patient, worst grade of each event type is reported. Grade 3 = Severe, Grade 4 = Life-threatening, Grade 5 = Fatal.
- Response Rate [ Time Frame: up to 3 years or time of disease progression ] [ Designated as safety issue: No ]Complete Response(CR) is a complete disappearance of all disease with the exception of nodes. No new lesions. previously enlarged organs must have regressed and not be palpable. Bone marrow(BM) must be negative if positive at baseline. Normalization of markers. CR Unconfirmed (CRU) does not qualify for CR above, due to a residual nodal mass or an indeterminate BM. Partial Response(PR) is a 50% decrease in the sum of products of greatest diameters (SPD) for up to 6 identified dominant lesions, including spleenic and hepatic nodules from baseline. No new lesions and no increase in the size of liver, spleen or other nodes.

- Determine 2-year overall survival of patients with newly diagnosed, bulky stage II or stage III or IV peripheral T-cell non-Hodgkin's lymphoma treated with cisplatin, etoposide, gemcitabine, and methylprednisolone.
- Determine the toxicity of this regimen in these patients.
- Determine the response rate (complete unconfirmed response, complete response, and partial response) in patients treated with this regimen.
- Determine progression-free survival of patients treated with this regimen.
OUTLINE: This is a pilot, multicenter study.
Patients receive cisplatin IV over 30-60 minutes, etoposide IV over 30-60 minutes, and methylprednisolone IV over 5 minutes on days 1-4. Patients also receive gemcitabine IV over 30-60 minutes on day 1. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed at 3-6 weeks, 3 months, and then every 6 months for up to 3 years.
PROJECTED ACCRUAL: A total of 55 patients will be accrued for this study within 3 years.
