Treatment for Aggressive, Stage I and Contiguous Stage II Adult NHL
Standard Treatment Options for Aggressive, Stage I and Contiguous Stage II Adult NHL
R-CHOP with or without IF-XRT
Treatment Options Under Clinical Evaluation for Aggressive, Stage I and Contiguous Stage II Adult NHL
Current Clinical Trials
Patients with stage I or contiguous stage II diffuse large B-cell lymphoma are candidates for combination chemotherapy with or without involved-field radiation therapy (IF-XRT).
The following drug combinations are referred to in this section:
- R-CHOP: rituximab, an anti-CD20 monoclonal antibody, + cyclophosphamide + doxorubicin + vincristine + prednisone.
Standard treatment options for aggressive, stage I and contiguous stage II adult NHL include the following:R-CHOP with or without IF-XRT
Evidence (CHOP vs. CHOP with IF-XRT):
- In a randomized trial with 7 years' median follow-up, 576 patients older than 60 years with early-stage disease received four cycles of CHOP with or without IF-XRT; there was no difference in 5-year event-free survival (EFS) (61% vs. 64%, P = .5) or overall survival (OS) (72% vs. 68%, P = .6).[Level of evidence: 1iiA]
- A randomized trial of 401 patients comparing eight cycles of CHOP to three cycles of CHOP with IF-XRT was initially reported as having an OS advantage for the combined–modality arm at 5 years, but a re-evaluation for OS at 9 years showed no difference in either arm of the study.[Level of evidence: 1iiA]
- A randomized study (EST-1484) of 210 patients who attained a radiologic complete remission after eight cycles of CHOP compared IF-XRT with no further therapy; there was no difference in OS at 10 years (68% vs. 65%, P = .24).[Level of evidence: 1iiA]
- A randomized trial of 631 patients younger than 60 years compared more intensive CHOP-based chemotherapy versus three cycles of CHOP with IF-XRT; with 4 years' median follow-up, the intensive chemotherapy was superior in 5-year EFS (82% vs. 74%, P > .001) and 5-year OS (90% vs. 81%, P = .001).[Level of evidence: 1iiA]
The confirmation of efficacy for rituximab in advanced-stage disease as evidenced in SWOG-S0014 (NCT00005089), for example, has suggested the use of R-CHOP with or without radiation therapy but its use is only supported by retrospective comparisons.[Level of evidence: 3iiiDiii]
- R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone); four to six cycles.
- R-CHOP (three to six cycles) + IF-XRT.
Evidence (R-CHOP vs. CHOP):
- A randomized study (DSHNHL-1999-1A) of 1,222 patients older than 60 years compared R-CHOP given every 2 weeks for six or eight cycles with CHOP given every 2 weeks for six or eight cycles. Although patients with early-stage disease were included in this trial, most patients had advanced-stage disease.
- With a median follow-up of 72 months, the EFS favored R-CHOP given every 2 weeks for six or eight cycles (EFS at 6 y, 74% vs. 56%; P < .001).
- The OS favored R-CHOP for only six cycles because of increased toxicity in the eight-cycle arm (OS at 6 y, 90% vs. 80%, P = .0004.[Level of evidence: 1iiA]
- There has been no comparison to standard R-CHOP or CHOP given every 3 weeks. There are no comparative studies to establish an optimal number of chemotherapy cycles for patients with early-stage disease.
Treatment options under clinical evaluation include the following:
- R-ACVBP (rituximab, doxorubicin, cyclophosphamide, vindesine, bleomycin, prednisone).
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with aggressive, stage I adult non-Hodgkin lymphoma and aggressive, contiguous stage II adult non-Hodgkin lymphoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.References
