Treatment of localized lymphoblastic lymphoma in the mandible typically involves a multimodal approach, including combination chemotherapy with protocols such as hyper-CVAD, followed by involved-field radiation therapy and central nervous system prophylaxis. The recommended treatment regimen includes combination chemotherapy with protocols such as hyper-CVAD (cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with high-dose methotrexate and cytarabine) or a modified Berlin-Frankfurt-Münster (BFM) protocol for 6-8 cycles, as seen in studies such as 1 and 2. This should be followed by involved-field radiation therapy to the mandible at doses of 30-36 Gy to eradicate any residual disease. Central nervous system prophylaxis with intrathecal chemotherapy (methotrexate, cytarabine, and hydrocortisone) is essential even in localized disease due to the high risk of CNS involvement in lymphoblastic lymphoma, as noted in 3 and 1. Some key points to consider in the treatment of localized lymphoblastic lymphoma include:
- The use of intensive chemotherapy regimens, such as hyper-CVAD, to achieve complete remission
- The importance of central nervous system prophylaxis to prevent CNS involvement
- The role of involved-field radiation therapy in eradicating residual disease
- The need for regular follow-up and monitoring to detect early relapse Treatment typically spans 2-3 years with an intensive induction phase followed by consolidation and maintenance phases. Regular follow-up with physical examinations, blood tests, and imaging studies every 3-6 months for the first two years is crucial for monitoring response and detecting early relapse, as seen in 1 and 2. This aggressive approach is necessary because lymphoblastic lymphoma is a highly aggressive malignancy with a tendency for systemic spread, and even apparently localized disease may harbor microscopic dissemination that requires systemic therapy for cure. In terms of specific treatment outcomes, a study by 1 found that combined intensive ALL-like induction and early consolidation chemotherapy followed by Auto-SCT and local radiation therapy resulted in high sustained cure rates, with 5- and 8-year PFS and OS rates of 76% and 84%, respectively. Similarly, a study by 2 found that the hyper-CVAD regimen was effective for remission induction in LBL, and SCT consolidation after hyper-CVAD induction produced better clinical outcomes than did continuation of hyper-CVAD. Overall, the treatment of localized lymphoblastic lymphoma in the mandible requires a comprehensive and aggressive approach to achieve optimal outcomes.
