Abstract
Extranodal marginal zone lymphoma of bronchus-associated lymphoid tissue (BALT) is a rare cancer for which optimal treatment strategies are undefined. Retrospective analyses suggest excellent outcomes with surgical resection for localized BALT lymphoma; however, the role of radiotherapy remains underexplored. We report the largest-to-date single-center analysis of 13 primary BALT lymphoma patients treated with radiotherapy. Of 15 treated lesions, we report a 100% response rate with complete response (CR) achieved in 67% of lesions. Among 10 lesions treated with very low-dose radiotherapy (VLDRT; 4 Gray [Gy]), 6 (60%) achieved a CR; among 5 lesions treated with full-dose radiotherapy (24-36 Gy), 4 (80%) achieved a CR. There were no local recurrences. Only one patient, treated with 30 Gy, developed an acute grade 3/4 toxic effect. There were no events of radiation-induced secondary malignancies. Our institutional experience indicates that radiotherapy, including VLDRT, is a safe and effective treatment for primary BALT lymphoma.

Clinical and radiological characteristics of patients with pulmonary marginal zone lymphoma: A single center analysis. Cancer Med 2020; 9:5051-5064.

Abstract
Pulmonary marginal zone lymphoma (PMZL) is the most common non‐Hodgkin lymphoma affecting the lung. PMZL is usually an indolent disease. Clinical and radiological variables associated with shorter survival are largely unknown and no consensus exists on preferred treatment strategy in PMZL. Herein we aimed to identify clinical and radiological features associated with shorter survival and inferior treatment outcomes. Forty patients with PMZL were analyzed. FDG‐avid disease was evident in most patients (93%) with staging PET/CT (n = 15). With a median follow‐up in treated patients (n = 38) of 8.4 years (range 0.07‐18.44), the median progression‐free survival (PFS) and overall survival (OS) were 7.5 years (95% CI 1.8‐9.5) and 15.7 years (95% CI 9.3‐NE) respectively. Shorter PFS was observed in patients who presented at diagnosis with elevated LDH, B symptoms, advanced stage and failed to achieve complete response (CR) after initial treatment. Patients with multifocal lung disease, extrapulmonary MZL and cavitary lesions on CT scans exhibited shorter PFS. Nevertheless, no clinical or radiologic findings were associated with shorter OS. All patients treated with surgery (n = 4) and radiation therapy (n = 3) achieved and remained in CR. No higher grade transformations occurred during the follow‐up period. PMZL exhibited excellent outcomes with a 15‐year PMZL‐related OS of 94.9% (95% CI: 81.25%‐98.7%). Radiation therapy and surgery are potentially curative strategies in localized PMZL.

Prognostic factors and nomogram for survival prediction in patients with primary pulmonary lymphoma: a SEER population-based study. Leuk Lymphoma 2019; 60:3406-3416.

Abstract
Primary pulmonary lymphomas (PPLs) are rare lymphoproliferative malignancies arising from the lungs. The prognostic factors and optimal management of PPL have not been clearly defined due to its rarity. This study sought to characterize the significant prognostic factors and develop a validated nomogram for individualized prediction of survival outcomes in patients with PPL. A total of 2325 patients diagnosed with PPL between 1983 and 2010 were identified using the Surveillance, Epidemiology, and End Results (SEER) database. Older age at diagnosis, males, Hispanic race, non-marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue histology, Ann Arbor stage IV were significantly associated with worse OS on multivariable analysis. All treatment modalities, including chemotherapy, surgery, and radiotherapy were independent predictors of survival on univariable analysis. The nomogram built demonstrated good discriminative ability and calibration, with the C-index of 0.690 and 0.730 in the training and validation cohorts, respectively.
