“…However, there was no beneficial effect of surgery on patients with UB-DLBCL. There are no surgical recommendations for UB lymphomas, mainly because of the morbidity and mortality associated with surgery ( 16 ). Regarding radiotherapy, our results suggested that radiation treatment had no benefit on UT-DLBCL patients.…”

ObjectiveDiffuse large B-cell lymphoma (DLBCL) is the most common histopathological type of non-Hodgkin’s lymphoma, which may arise from various extranodal sites. Little is known about the clinical characteristics and survival outcomes of primary DLBCL of the urinary tract (UT). Thus, we conducted this study to explore the independent prognostic factors of patients with UT-DLBCL using the Surveillance, Epidemiology, and End Results (SEER) database.Materials and MethodsWe searched the Surveillance, Epidemiology, and End Results (SEER) database for the data of patients diagnosed with UT-DLBCL between 1975 and 2016. Data, including demographic tumour stage and therapeutic strategies, such as surgical resection, radiation therapy, and chemotherapy, were collected. The impact of these factors on survival outcomes, including overall survival (OS) and disease-specific survival (DSS), was analysed using Kaplan–Meier curves.ResultsFour-hundred and eighty-nine patients who met the inclusion criteria were enrolled in the data analysis. The median age was 69 years old. Most cases of UT-DLBCL (72.39%) originated from the kidney, followed by the urinary bladder (24.95%). Both surgical resection and chemotherapy can significantly improve OS and DSS. Patients older than 75 years had the worst survival outcomes. Stage IV DLBCL may be a poor prognostic factor.ConclusionTo the best of our knowledge, this is the largest population-based study of UT-DLBCL. Advanced age, male gender, lack of surgical resection or chemotherapy, and stage IV DLBCL were poor prognostic factors.

“…Furthermore, treatment for the condition has changed over time. 2 In the past, surgical treatment, such as total cystectomy or partial cystectomy, was principally used; however, it was found that there was no difference in the recurrence rate between surgical and non-invasive treatments. Since 1990, chemotherapy or radiation therapy, which can preserve the bladder, has become the mainstay of treatment.…”

We report the cases of patient with primary mucosa-associated lymphoid tissue (MALT) lymphoma of the bladder who successfully treated with local radiation therapy after transurethral resection of the bladder tumor. She maintains good activity of daily living without relapse. We recommend this strategy for localized MALT lymphoma of the bladder, because it provide better quality of life for elderly patients.

“…MALT lymphoma is a unique subtype of B-cell lymphoma predominantly involving extranodal sites, such as the stomach, orbit, conjunctiva, salivary glands, thyroid and lungs[ 2 , 5 - 7 ]. The bladder is rarely involved, accounting for only 0.2% of extranodal lymphomas[ 8 ]. The risk factors include chronic inflammation, urinary tract infections and autoimmune diseases[ 9 , 10 ].…”

BACKGROUND Mucosal-associated lymphoid tissue extranodal marginal zone (MALT) lymphoma is a low-grade tumor that rarely occurs in the urinary bladder. There is currently no consensus on the common imaging findings or most appropriate treatment in MALT lymphoma in the urinary bladder due to the limited number of reports. CASE SUMMARY A 48-year-old woman was admitted to the hospital with a 1-year history of macroscopic hematuria. Imaging showed a large homogeneous mass with an unclear boundary and an irregular morphology in the bladder. The mass had an abundant blood supply. For further diagnosis, transurethral cystoscopic biopsy and bone marrow biopsy was performed, and the patient was finally diagnosed with primary MALT lymphoma of the bladder. R-CHOP chemotherapy was carried out. After three cycles of chemotherapy, the mass disappeared and the bladder wall thickness was only 4 mm, which indicated excellent therapeutic response to the chemotherapy. To date, the patient remains asymptomatic and she visits our hospital regularly for the completion of the remaining chemotherapy cycles. CONCLUSION Primary MALT lymphoma of the bladder is rare, and there are certain characteristics in the ultrasonographic findings. Imaging findings play an important role in evaluating the therapeutic efficacy and are critical during long-term follow-up after therapy.
