Core Tip
Core Tip: Since duodenal-type follicular lymphoma (D-FL) progresses more indolently than common nodal FL, the “watch and wait” approach is frequently used without intervention. To elucidate the clinical assessments of long-term follow-up in cases of D-FL with treatment intervention, we retrospectively examined 5 D-FL patients for more than 10 years after treatment at our center. All 5 patients eventually achieved complete remission and survived for a long period. However, 3 patients experienced recurrence, and 1 patient died of the primary disease 21 years after first onset. In the future, it will be necessary to establish criteria for how to treat Stage IV “advanced” D-FL.
