ABSTRACT
Objective: Laryngeal chondrosarcomas (LCS) are rare tumors with
good prognosis. The coexistence of LCS and cervical metastasis of
papillary thyroid carcinoma (PTC) is scarce. The main objective of this
research was to review clinical aspects and management of LCS . A
secondary objective was to find the coexistence of LCS with cervical
Lymph node metastasis of papillary thyroid carcinoma (LNMPTC) in all the
cases included in the search.
Design: A Systematic Review was performed using PubMed, Web of
Science, Scopus and Embase databases. We followed PRISMA guidelines and
the PECOS method to characterize different aspects of LCS. Reports of
laryngeal chondrosarcoma were included and information about symptoms,
imaging technique, treatment modality, histopathological diagnosis,
location, tumor size, recurrence, and follow-up data was extracted.
Results: Three hundred and eighty one cases of LCS were
included. The average age was 61.1 years. The most common symptoms were
dyspnea and hoarseness. Cricoid cartilage was the most usual location.
Survival was affected by histologic differentiation, tumoral location
and surgical technique. We identified the coexistence of LCS and PTC in
2 cases. In none of them the authors reported LNMPTC.
Conclusion : The coexistence of LCS and PTC is rare. LCS is a
tumor with good prognosis. Different approaches are described in
literature.
