Purpose: It is well known that the majority of the extranodal marginal zone lymphomas of mucosa-associated lymphoid tissues (MALT lymphomas) are associated with microbiota, e.g., gastric MALT lymphoma with Helicobacter pylori. In general, they are very sensitive to low-dose radiotherapy and chemotherapeutic agents. The microbiota profile is not clearly elucidated in bronchus-associated lymphoid tissue (BALT) lymphoma, a rare type of MALT lymphoma in the lung. Thus, this study aimed to clarify the intratumor microbiome in BALT lymphoma using the third-generation next-generation sequencing (NGS) method. Materials and Methods: DNAs were extracted from 12 formalin-fixed paraffin-embedded (FFPE) tumor tissues obtained from BALT lymphoma patients diagnosed between 1990 and 2016. 16S rRNA gene was amplified by polymerase chain reaction. Amplicons were sequenced using a Nanopore platform. Next-generation sequencing analysis was performed to assess microbial profiles. For comparison, FFPE specimens from nine non-cancerous lung tissues were also analyzed. Results: Specific bacterial families including Burkholderiaceae, Bacillaceae, and Microbacteriaceae were associated with BALT lymphoma by a linear discriminant analysis effect size approach. Although the number of specimens was limited, BALT lymphomas exhibited significantly higher microbial abundance and diversity with distinct microbial composition patterns and correlation networks than non-cancerous lung tissues. Conclusion This study provides the first insight into intratumor microbiome in BALT lymphoma using the third-generation NGS method. A distinct microbial composition suggests the presence of a unique tumor microenvironment of BALT lymphoma.

Purpose: Cystoscopy is a diagnostic test performed frequently in urology outpatient clinics. Despite the large number of inspections, the associated pain, discomfort, or anxiety can markedly affect patient compliance and adherence to subsequent surveillance protocols. This study conducted a prospective, randomized study to investigate the potential efficacy of music and pyuria on pain or anxiety during outpatient cystoscopy. Materials and Methods: In this single-institution, randomized study, the participants were assigned to a music-intervention or non-music control group. The music-intervention group underwent an identical procedure with the addition of Johann Sebastian Bach’s “Air on the G String” from Suite No. 3 in D major, BWV 1068. Urinalysis was performed to determine if pyuria affects pain during the procedure. Results: The patient-reported outcomes, encompassing the changes in the STAI-X-1 (State-Trait Anxiety Inventory-X-1) scores, subjective levels of discomfort, embarrassment, satisfaction, and pain, were similar in the two groups. In contrast, the surgeons reported statistically significant differences in their evaluations of the same items as patient-reported outcomes of the two groups. The patient-reported pain showed no significant differences between the pyuria-negative group (0-2 and 3-5 WBC/HPF) and pyuria-positive group (>5 WBC/HPF). Conclusions The data from this study do not support the hypothesis that musical intervention during cystoscopy alleviates pain or anxiety to any significant extent.In addition, pyuria did not affect the patient’s reported pain. Nevertheless, a notable impact was observed in the surgeons’ assessments, suggesting that the musical accompaniment may alter the surgeons’ perception of patient pain and anxiety levels throughout the procedure.
