HIV-Positive Patient With an Obstructing Laryngeal Mass

Non-squamous Cancers of the Larynx

PURPOSE OF REVIEW

Although non-squamous tumors of the larynx are really rare, they may not always be viewed from the same perspective in the multidisciplinary treatment approach once the diagnosis is made. In this review, non-squamous tumors of the larynx and current approaches in treatment will be discussed.

RECENT FINDINGS

When the studies and meta-analyses presented in the last 5 years are evaluated, it is seen that these tumors usually show non-specific symptoms. Due to their submucosal location, the stage of the disease at the time of diagnosis is often advanced. In the literature, treatment may vary in these particular cases. The majority of non-squamous tumors of the larynx includes minor salivary gland tumors, neuroendocrine carcinomas, sarcomas, cartilage tumors, and malignant melanomas. Once treating a patient with these diagnoses, it should be kept in mind that the histopathological subtype is almost as important as the stage of the tumor.

Kaposi Sarcoma of the Larynx: A Systematic Review

OBJECTIVE

Kaposi sarcoma (KS) of the larynx is a rare disease with few cases reported in the literature. This study aims to provide a comprehensive review of laryngeal KS, including patient characteristics, treatment, and clinical outcomes.

DATA SOURCES

PubMed, CINAHL, SCOPUS, and Cochrane Library.

REVIEW METHODS

A systematic review of the published English literature was conducted. An electronic search and bibliographic examination of articles pertaining to laryngeal KS were performed. Demographic data, tumor site, treatment strategies, follow-up, and outcome were analyzed.

RESULTS

A total 77 cases from 50 articles were included in the review. The mean age was 47.6 years (range, 8-81). There was an 8.6:1 male:female ratio. The most common presenting symptoms were dyspnea (n = 35) and hoarseness (n = 25). Laryngeal KS arose most frequently in the supraglottic region (n = 16). Chemotherapy alone (n = 27) was the most common treatment modality in patients with AIDS-associated KS, and surgical excision alone (n = 7) was most common in patients with other subtypes of KS (eg, classic, transplant associated). Average follow-up was 20.4 months (range, 0.75-120). Most patients with AIDS-associated KS died of other causes (n = 25), but most patients with other subtypes of KS were alive with no evidence of disease at follow-up (n = 13).

CONCLUSION

This review contains the largest pool of laryngeal KS cases to date. Long-term outcomes were generally unfavorable, often due to advanced HIV disease at the time of diagnosis.
