ABSTRACT

INTRODUCTION:

Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma (SCC). Because of its rarity, both clinical and prognostic features of this variant are not well known.

OBJECTIVE:

In this study, we aimed to determine the frequency of BSCC and other SCC variants among all laryngeal SCC cases, and to determine clinical and prognostic features of BSCC variant. Study

design:

retrospective cohort study. Evidence level Level 2b. MATERIAL AND

METHODS:

Records of the patients who had laryngeal SCC surgically treated at our institute between 2007 and 2013 were retrospectively reviewed.

RESULTS:

Among 198 subjects who had laryngeal SCC surgically treated, the frequency of the variants of SCC other than classical variant was 10.1% (20/198). The most common SCC variant was BSCC (6.6%). Eleven (84.6%) patients with BSCC were at an advanced stage at the presentation (p > 0.05). The 3-year overall survival and disease-free survival rates were 63% and 53% respectively.

CONCLUSION:

BSCC variant may be more common than previously reported. Since almost the half of patients experiences disease recurrence in the early period, multimodal treatment strategies should be employed at initial treatment, and a close follow-up is strongly recommended for this aggressive SCC variant. .
RESUMO

INTRODUÇÃO:

O carcinoma escamoso basaloide (CEB) é um raro subtipo do carcinoma de célula escamosa (CCE). Em decorrência de sua raridade, os aspectos clínicos e prognósticos dessa variante não são bem conhecidos.

OBJETIVO:

Determinar a frequência de CEB e de outras variantes do CCE entre todos os casos de CCE da laringe, assim como os aspectos clínicos e prognósticos da variante CEB.

MÉTODOS:

Trata-se de um estudo de coorte retrospectivo. Nível de evidência 2b Os registros dos pacientes tratados cirurgicamente para CCE de laringe em nossa instituição entre 2007 e 2013 foram retrospectivamente revisados.

RESULTADOS:

Foram anotados 198 pacientes tratados cirurgicamente para CCE de laringe. A frequência das variantes de CCE diferentes da variante clássica foi 10,1% (20/198). A variante de CCE mais comum foi CEB (6,6%). Por ocasião da apresentação inicial, 11 (84,6%) pacientes com CEB estavam em estágio avançado (p > 0,05). Os percentuais de sobrevida geral após três anos e de sobrevida livre da doença foram 63% e 53%, respectivamente.

CONCLUSÃO:

A variante CEB pode ser mais comum do que o informado anteriormente. Considerando que praticamente metade dos pacientes sofre recorrência da doença em seu período inicial, devem ser introduzidas estratégias terapêuticas multimodais no tratamento inicial; além disso, recomendamos enfaticamente um cuidadoso seguimento para essa agressiva variante do CCE. .
