Low-Stage Childhood NHL Treatment
Patients with stage I and II disease have an excellent prognosis, regardless of histology. A Children’s Cancer Group study demonstrated that pulsed chemotherapy with cyclophosphamide, vincristine, methotrexate, and prednisone (COMP) administered for 6 months for low-stage (stage I or II) nonlymphoblastic non-Hodgkin lymphoma (NHL) was equivalent to 18 months of therapy with radiation to sites of disease, resulting in more than 85% disease-free survival (DFS) and more than 90% overall survival (OS). However, patients with lymphoblastic lymphoma had a much inferior outcome.[1,2] A Pediatric Oncology Group (POG) study tested 9 weeks of short, pulsed chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), with or without radiation to involved sites and with or without 24 weeks of maintenance chemotherapy. The results showed no benefit of radiation or maintenance chemotherapy, but the DFS for nonlymphoblastic lymphoma was superior to that of lymphoblastic lymphoma (90% vs. 60%).
For low-stage mature B-cell NHL (Burkitt lymphoma or diffuse large B-cell lymphoma), DFS is about 95%. The Berlin-Frankfurt-Munster (BFM) group has treated risk group R1 (completely resected disease) with two cycles of multiagent chemotherapy (GER-GPOH-NHL-BFM-90 and GER-GPOH-NHL-BFM-95).[4,5] For unresected stage I/II disease (R2), patients received a cytoreductive phase followed by five cycles of chemotherapy.[4,5] In the NHL-BFM-90 study, it was shown that reducing the dose of methotrexate did not affect the results for low-stage disease. In NHL-BFM-95, it was demonstrated for low-stage disease that prolonging the duration of methotrexate infusion did not improve outcome. The French Society of Pediatric Oncology (SFOP) and French-American-British (FAB) studies have treated all completely resected stage I and abdominal stage II (group A) with two cycles of multiagent chemotherapy, without intrathecal chemotherapy (COG-C5961 [FAB/LMB-96]).[Level of evidence: 2A] For unresected stage I/II disease (group B), the above-mentioned FAB study demonstrated that reducing the duration of therapy to four cycles of chemotherapy following a cytoreduction phase and reducing the cumulative doses of cyclophosphamide and doxorubicin did not affect outcome.
For low-stage lymphoblastic lymphoma (stage I/II disease), about 60% of patients can achieve long-term DFS with short, pulsed chemotherapy.[2,3] However, with the use of an acute lymphoblastic leukemia approach with induction, consolidation, and maintenance therapy for a total of 24 months, DFS rates higher than 90% have been reported for children with low-stage lymphoblastic lymphoma.[8-10]
For low-stage anaplastic large cell lymphoma, the best results have come from using pulsed chemotherapy similar to mature B-cell NHL therapy. In the POG study for low-stage lymphoma using three cycles of CHOP, a 5-year event-free survival (EFS) of 88% for large cell lymphoma (anaplastic large cell lymphoma and diffuse large B-cell lymphoma) patients was reported. The BFM group has used three cycles of chemotherapy following a cytoreductive prophase for completely resected stage I/II disease. The FRE-IGR-ALCL99 trial used three cycles of chemotherapy following cytoreductive prophase for patients with stage I completely resected disease. The minority of stage I patients had complete resections (6 out of 36) but there were no treatment failures for these six patients. The therapy for patients without complete resection was the same as the therapy for patients with disseminated disease and the 3-year EFS (81%) and OS (97%) were not statistically different from the outcomes for patients with higher stage disease.[Level of evidence: 2A]
Primary cutaneous anaplastic large cell lymphoma presents a particular problem. The diagnosis can be difficult to distinguish from more benign diseases such as lymphoid papulosis. Primary cutaneous anaplastic large cell lymphoma usually does not express ALK and may be treated successfully with surgical resection and/or local radiation therapy without systemic chemotherapy. There are reports of surgery alone being curative for ALK-positive cutaneous anaplastic large cell lymphoma, but extensive staging and vigilant follow-up is required.
Follicular lymphoma is rare in children, with only case reports and case series to guide therapy. Although outcome is generally very good, treatments range from surgery only to multiagent chemotherapy and even autologous blood or marrow transplant.[15-20] It appears that for pediatric patients without the BCL2 rearrangement and a high proliferative index, surgical resection with no further treatment is sufficient for completely resected, localized disease. For those with tumors that have the BCL2 rearrangement, treatment like that of adult patients with follicular lymphoma is preferred (refer to the PDQ summary on Adult Non-Hodgkin Lymphoma Treatment for more information).
Subcutaneous mature T-cell lymphomas are very rare in children. An oral retinoid (bexarotene) has been reported to be active against subcutaneous T-cell lymphomas in children.
Standard treatment options are based on histology; however, current data do not suggest superiority between regimens listed below for a specific histology.
