Primary Palatine Tonsil Non-Hodgkin Lymphoma in Western Romania: A Comparison of Lower-Stage and Advanced-Stage Disease

TL;DR

This study examines non-Hodgkin lymphoma in the tonsils of patients in Western Romania, comparing outcomes between early and advanced stages of the disease.

Contribution

The study provides insights into primary palatine tonsil NHL in a region with limited healthcare access, comparing lower- and advanced-stage disease characteristics.

Findings

Advanced-stage disease was more common (55.9%) and associated with higher B symptoms and elevated LDH levels.

Combined chemoradiotherapy was more frequently used in lower-stage disease.

No significant difference in relapse rates was observed between the groups.

Abstract

Background: Limited data exist on primary palatine tonsil Non-Hodgkin lymphoma (NHL) from regions with constrained healthcare access. This study investigated this malignancy in Western and South-Western Romania, comparing lower-stage (Ann-Arbor I-III) and advanced-stage (IV) disease. Methods: A retrospective cohort study (2010–2019) at a tertiary referral hospital included 59 patients with primary palatine tonsil NHL. Data on demographics, clinical presentation, comorbidities (including viral hepatitis B/C), histology, International Prognostic Index (IPI) score, treatment, and outcomes were collected. Statistical comparisons between lower-stage (n = 26) and advanced-stage (n = 33) groups were performed. Results: A high proportion presented with advanced-stage disease (55.9%). The advanced-stage group had significantly more B symptoms (90.9% vs. 69.2%, p = 0.038) and elevated LDH levels (93.9% vs. 57.7%, p = 0.013). Viral hepatitis B and/or C infection was more frequent in advanced-stage disease (30.3% vs. 15.4%, p = 0.44). Combined chemoradiotherapy was more commonly used in lower-stage disease (38.46% vs. 12.12%, p = 0.019). There was no statistically significant difference in relapse rates between the groups. Conclusions: This study highlights the substantial burden of advanced-stage primary palatine tonsil NHL in Western Romania, suggesting a need for improved early detection. The association between viral hepatitis and advanced-stage, although not statistically significant, warrants further investigation. These findings may inform tailored management approaches in resource-constrained settings.
