Clinical features and survival outcomes of patients with lymphoplasmacytic lymphoma, including non-IgM type, in Korea: a single-center experience.

ABSTRACT:

Background

The incidence of lymphoplasmacytic lymphoma (LPL) is lower in Asian than in Western populations. Few studies have described the clinical features and treatment outcomes of patients with LPL, including non-IgM LPL, in East Asia.

Methods

We retrospectively analyzed patients diagnosed with LPL at Asan Medical Center between January 2001 and March 2016. We evaluated the clinical features and survival outcomes of patients with LPL and non-IgM LPL and compared these data with those of patients with LPL/Waldenström's macroglobulinemia (WM).

Results

The median age at diagnosis of patients with LPL was 61.5 years (range, 34-77 yr); most patients were male (91%). Approximately three-quarters of the 22 patients with LPL were in the low or intermediate risk groups according to the International Prognostic Scoring System for Waldenström's Macroglobulinemia classification. The median follow-up duration was 75 months [95% confidence interval (CI), 48-102 mo], and the median overall survival (OS) was 81 months (95% CI, 0-167 mo). The number of patients in the non-IgM LPL group who exhibited extramedullary involvement was higher than in the LPL/WM group. OS of the LPL/WM group was improved compared with that of the non-IgM LPL group [median not reached vs. 10.0 mo (95% CI, 0-36.7); P=0.05].

Conclusion

We present a single-center experience of 22 patients with LPL, including a non-IgM cohort, in Korea. The treatment of non-IgM LPL was heterogeneous, and patients with non-IgM LPL showed a higher 5-year mortality rate and more adverse prognostic factors than those with LPL/WM.

Project description:ObjectiveThe worldwide incidence of primary small intestinal lymphoma (PSIL) is increasing. However, little is known about the clinical and endoscopic characteristics of this disease. The aim of this study was to investigate the clinical and endoscopic data of patients with PSIL, with the goal of enhancing our understanding of the disease, improving diagnostic accuracy, and facilitating more accurate prognosis estimation.MethodsNinety-four patients diagnosed with PSIL were retrospectively studied at Qilu Hospital of Shandong University between 2012 and 2021. The clinical data, enteroscopy findings, treatment modalities, and survival times were collected and analyzed.ResultsNinety-four patients (52 males) with PSIL were included in this study. The median age of onset was 58.5 years (range: 19-80 years). Diffuse large B-cell lymphoma (n=37) was the most common pathological type. Abdominal pain (n=59) was the most frequent clinical presentation. The ileocecal region (n=32) was the most commonly affected site, and 11.7% of patients had multiple lesions. At the time of diagnosis, the majority of patients (n=68) were in stages I-II. A new endoscopic classification of PSIL was developed, including hypertrophic type, exophytic type, follicular/polypoid type, ulcerative type, and diffusion type. Surgery did not show a significant increase in overall survival; chemotherapy was the most commonly administered treatment. T-cell lymphoma, stages III-IV, "B" symptoms, and ulcerative type were associated with poor prognosis.ConclusionThis study provides a comprehensive analysis of the clinical and endoscopic features of PSIL in 94 patients. This highlights the importance of considering clinical and endoscopic characteristics for accurate diagnosis and prognosis estimation during small bowel enteroscopy. Early detection and treatment of PSIL is associated with a favorable prognosis. Our findings also suggest that certain risk factors, such as pathological type, "B" symptoms, and endoscopic type, may affect the survival of PSIL patients. These results underscore the need for careful consideration of these factors in the diagnosis and treatment of PSIL.
