Radiotherapy in marginal zone lymphoma

چکیده
PURPOSE To evaluate the efficacy of radiotherapy (RT) for early-stage nodal and extranodal marginal zone lymphoma (MZL). MATERIALS AND METHODS Patients with stage I (n = 22) and stage II (n = 8) MZL, who were treated with RT were reviewed. The primary tumor localisation was in the orbita (n = 12), stomach (n = 8), head and neck other than the orbita (n = 8), breast (n = 1) and one case of marginal zone lymphoma of the skin (n = 1). The median radiotherapy dose was 40 Gy (5 to 45 Gy). RESULTS The median follow-up time was 103 months. The 5-year overall survival and event-free survival rates were 85 ± 7% and 71 ± 9%, respectively. There was no infield recurrence. Recurrence occurred outside of the radiation field in six patients. The relapses were treated with salvage RT and had excellent local control (100%) at five years after salvage RT. CONCLUSIONS Localized extranodal MZL have an excellent prognosis following moderate-dose RT. RT is also an effective salvage therapy in cases of localized recurrence. Further clinical studies should evaluate the optimal dose for MZL.

We report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. Thorax, abdomen and pelvis Contrast-Enhanced Computed Tomography (CECT) showed lymph nodes, spleen and liver lesions. Axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (MZL) at stage IV was postulated, then the p...

The aim of the present study was to determine the optimal dose and optimal target volume for marginal zone lymphoma of the ocular adnexa. Between January, 2008 and December, 2013, 40 patients with histologically proven primary marginal zone lymphoma of the ocular adnexa who underwent radiotherapy at the Tokyo Medical University were evaluated. The prescribed dose was 30 Gy in 15 fractions to th...

BACKGROUND Marginal zone lymphomas (MZL) are indolent B-cell lymphomas with variable symptoms related to lymphoma location. Patients with such lymphoma often have an excellent prognosis. Concerning treatment, no large prospective trials have been published, making therapeutic decisions difficult. CASE REPORT The Authors present the case of a female patient with an MZL which was slowly progres...
