Small cell neuroendocrine carcinoma of larynx: case series and literature review

J Laryngol Otol. 2015 Sep;129(9):910-5. doi: 10.1017/S0022215115001668. Epub 2015 Jul 15.

Abstract

Background: Primary small cell neuroendocrine carcinoma of larynx is a rare, aggressive type of malignancy. As only about 200 cases worldwide have been reported, any larger institutional experience is valuable. This study reports our experience in managing this rare entity.

Methods: Of the nine patients identified, three had metastatic cancer at the time of diagnosis. Four patients underwent radical treatment: one was managed surgically followed by adjuvant chemotherapy and consolidation radiotherapy; the remaining three were treated with neoadjuvant chemotherapy and definitive radiotherapy.

Results: Of the 4 patients treated with radical intent, 1 was alive and disease free after 99 months, 2 died of metastatic disease after 22 and 26 months, and 1 was alive after 20 months with a diagnosis of recurrent disease.

Conclusion: Our relatively small number of patients confirms other centres' experiences. This cancer has a poorer prognosis than most other head and neck cancers. Although the logistics would be challenging, there is a need for international multicentre trials for this disease modelled on those performed for other cancers, as has been done for paediatric malignancies.
