Abstract
Vocal cord nodule is a common reactive transformation of the laryngeal mucosa encountered routinely. Although benign, rare instances of stromal atypia have been demonstrated, which can often be confused with other spindle cell lesions. There is a dearth of literature explaining this peculiar transformation. Hence, the diagnosis of these lesions can be put-forth only after histopathological evaluation and appropriate immunohistochemical analysis. Herein, we report a case of a 55-year-old male who presented with vocal cord nodule with stromal atypia.

BIOLOGY 2021; 10:biology10121268. [PMID: 34943184 PMCID: PMC8698952 DOI: 10.3390/biology10121268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 11/28/2021] [Accepted: 12/02/2021] [Indexed: 11/16/2022]
Abstract
Simple Summary Vocal nodules, together with vocal polyps, are the most common benign vocal cord structures that are thought to be caused by extensive vocal abuse (shouting, talking loudly for prolonged periods) and are routinely treated surgically. However, surgical excision of these nodules, does not exclude the possibility of recurrence of these nodules, especially if lifestyle changes are not adapted to prevent phonetic trauma. Furthermore, the etiopathogenetic pathways governing the formation and maintenance of these nodules are not known. Herein, we investigated the etiopathogenetic markers for proliferation, apoptosis, growth, ischemia (tissue hypoxia), inflammation and innervation to elucidate the causative pathways. We found a profound and significant intensification of apoptosis in tissue epithelium, which strongly correlated with proliferative, ischemic, and inflammatory changes, highlighting the underlying complex interactions between various mechanisms on a cellular and tissue level, which occur during the morpho-pathogenesis of vocal nodules. Abstract Vocal nodules (or Singer’s nodules) are benign vocal cord structures which are commonly encountered by clinicians. Though phonetic trauma/abuse is thought to be the main cause of the development of vocal nodules, the exact etiopathogenesis remains unknown. Hence, we compared the immunohistochemical markers for proliferation (Ki-67), apoptosis (TUNEL), growth (EGFR), ischemia (VEGF), inflammation (IL-1α and 10), and immunoreactive innervation (PGP 9.5), in vocal nodule tissue samples obtained from 10 females (17–56 years) and vocal cord tissue from seven controls. A statistically significant increase in Ki-67, TUNEL, EGFR, VEGF and IL-1α expression was noted (p < 0.05) between nodule tissue and control tissue in both epithelial and subepithelial layers. However, the difference was non-significant for both IL-10 and PGP 9.5 (p > 0.05). All markers demonstrated moderate to strong positive correlations, except for IL-10. These findings suggest increased cellular growth and proliferation in vocal nodules coupled with a persistent presence of inflammatory and ischemic environment. Furthermore, global prevalence of apoptotic cells and decreased anti-inflammatory cytokines highlight the presence of underlying complex mechanisms in the etiopathogenesis of vocal nodules, with age having a negligible impact on the marker levels. Our results could potentially further our knowledge in understanding the effects of different treatment modalities available at the cellular level.

IMP3 Protein Overexpression Is Linked to Unfavorable Outcome in Laryngeal Squamous Cell Carcinoma. Cancers (Basel) 2021; 13:cancers13174306. [PMID: 34503117 PMCID: PMC8430545 DOI: 10.3390/cancers13174306] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/23/2021] [Accepted: 08/23/2021] [Indexed: 02/02/2023] Open
Abstract
Simple Summary IMP3 expression was analyzed in patients with malignant (laryngeal squamous cell carcinoma), semi-malignant (dysplasia) and benign (nodules, polyps) laryngeal lesions and correlated with clinical characteristics. Higher IMP3 stains were particularly found in malignant laryngeal pathologies, which might be useful for differentiation between premalignant and malignant lesions. In laryngeal cancer patients, higher IMP3 expression was associated with positive neck nodes and worse disease-specific survival. Abstract Background: The aim of this study was to (i) determine IMP3 protein expression in benign and malignant laryngeal lesions, (ii) compare its expression to Ki-67, p53, cyclin D1, and (iii) finally, to examine the prognostic power of IMP3 in squamous cell carcinomas of the larynx (LSSC). Methods: IMP3 protein expression was evaluated in 145 patients, including 62 LSCC, 45 dysplasia (25 with low and 20 with high-grade dysplasia), and 38 benign lesions (vocal cord polyps and nodules). Results: IMP3 was significantly higher expressed in LSCC compared to dysplasia and benign lesions (p < 0.001; p < 0.001, respectively). Similarly, higher expression patterns were observed for Ki-67 and p53, whereas cyclin D1 was equally distributed in all three lesions. IMP3 (p = 0.04) and Ki-67 (p = 0.02) expressions were significantly linked to neck node positivity, and IMP3 overexpression to worse disease-specific survival (p = 0.027). Conclusion: Since IMP3 showed significantly higher expression in laryngeal carcinomas, but not in high- or low-grade dysplasia, it serves as a useful marker to differentiate between invasive and noninvasive lesions. Higher IMP3 expression represented a significantly worse prognosticator for clinical outcomes of patients with squamous cell carcinoma of the larynx.

Pathol Res Pract 2020; 216:152974. [PMID: 32370989 DOI: 10.1016/j.prp.2020.152974] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/11/2020] [Accepted: 04/13/2020] [Indexed: 12/15/2022]
Abstract
OBJECTIVE The aim of the study was to investigate the expression of ribonuclear protein IMP3 in laryngeal carcinogenesis, together with other biomarkers of carcinogenesis (Ki-67, p53 and cyclin D1), and to evaluate their predictive values. METHODS The study included 153 patients divided into three groups: 68 operated for primary invasive laryngeal squamous cell carcinoma (LSCC); 41 with precancerous lesions of atypical and abnormal hyperplasia; 44 with hyperplastic laryngeal nodule without atypia. Tissue microarray technique was used for immunohistochemical analysis. RESULTS All markers showed statistically significant differences between the three groups. The percentage of IMP3 positive cells is statistically significantly higher in LSCC group in comparison to precancerosis and control group. The percentage of Ki-67 positive cells is statistically significantly higher in LSCC group in comparison to precancerosis and control group. The percentage of p53 positive cells in LSCC group is statistically significantly higher than the control group and higher, but not statistically significant, than the precancerosis group. The percentage of cyclin D1 positive cells is statistically significantly higher in LSCC group than in precancerosis group and higher, but not statistically significant, than in the control group. All analyzed markers have good predictive values (AUC > 0.6), but the percentage of IMP3 positive cells is the only statistically significant marker in predicting whether the patient has LSCC or not. CONCLUSION Expression of Ki-67 and pronouncedly IMP3 generally follow the same pattern where control and precancerosis are similar and LSCC significantly differs, as opposed to p53 and cyclin D1. IMP3 expression increase possibly has an important diagnostic, therapeutic (in terms of the need for additional therapy after surgery) and prognostic value. Further studies on the exact molecular mechanisms behind it are, of course, needed.
