Abstract
OBJECTIVES/HYPOTHESIS
Primary lymphoma of the larynx is rare. The symptoms are ambiguous and nonspecific, and confirmation of the diagnosis is often difficult. To better understand the clinical characteristics of this distressing disease, we performed an individual participant data meta-analysis focusing on the diagnoses and treatment outcomes.
STUDY DESIGN
Systematic review article.
METHODS
A literature search of the MEDLINE, Embase, and Cochrane library databases was conducted using the following Medical Subject Headings and keywords: "primary," "lymphoma," "cancer," and "larynx." The individual data of 57 patients from 41 articles were selected based on the inclusion criteria for the analysis.
RESULTS
The mean age of the 57 patients at the time of diagnosis was 53.9 ± 18 years, and there was a preponderance of male patients (male:female = 35:22). The mean follow-up was 33.2 ± 40.5 months. The most common symptom was hoarseness (70.2%). Extension of the lymphoma was found in the supraglottic larynx (63.2%). B-symptoms were noted in only 14.0% of patients. The treatment method and disease extent were not significant factors. The significant prognostic factors were the biopsy frequency (P = .000), B-symptoms (P = .032), and cell type (P < .001).
CONCLUSIONS
From an analysis of larynx lymphoma patients, accurate biopsy, the presence of B-symptoms, and the cell type of the lymphoma are important to the prognosis. However, the treatment method was not effective in predicting the prognosis.
LEVEL OF EVIDENCE
