Primary small-cell carcinoma of the oesophagus with spontaneous oesophageal perforation following chemotherapy

Carcinoma de Pequena Células em Esôfago: Relato de Caso e Revisão

O caso de um paciente do sexo masculino com 54 anos, portador de carcinoma de pequenas Células primitivo em terço inferior de esôfago. As manifestações iniciais da doença se caracterizaram por emagrecimento acentuado e dores epigástricas com 3 meses de evolução. Ao exame físico observamos sinais evidentes de doença consuntiva. O estadiamento oncológico revelou acometimento secundário de linfonodos para-aórticos, mesentéricos e do tronco celíaco (doença extensa), além de possível invasão de aorta descendente. O tratamento baseou-se na quimioterapia com cisdiaminodicloroplatinum e etoposide, obtendo-se remissão clínica completa com três ciclos. Como consolidação do resultado, o paciente recebeu radioterapia externa dirigida ao local do tumor primário, porém a resposta obtida não se manteve, havendo progressão local e sistêmica após 40 dias do término da radioterapia. O óbito se deu em função de infecção respiratória e múltiplas metástases 9 meses do diagnóstico. Nós discutimos o mau prognóstico deste tipo de tumor, sobretudo em função do comportamento biológico agressivo e fazemos uma análise crítica da orientação terapêutica proposta, concluindo que o tratamento principal para os carcinomas de pequenas células de esôfago locorregionalmente avançado deve ser baseado na quimioterapia.

A rare rarity: Neuroendocrine tumor of the esophagus

Esophageal Neuroendocrine tumors (NETs) are rare, aggressive and lacking specific symptoms. This causes a diagnostic delay, worsening the prognosis. Numerous cases are reported in literature, without a consensus on the management. Our aim was to clarify epidemiology, clinical presentation, diagnostic, therapeutic management of esophageal NETs. Extensive literature search identified a total of 226 articles. One hundred twenty-five articles (n = 1676) met the inclusion criteria, showing that: the incidence of esophageal NET varies geographically; men (60-70 years) are more affected; smoking and alcohol abuse are the major risk factors; dysphagia, weight loss, appetite loss are the most common clinical features. The histotypes include high-grade small and large cell esophageal carcinomas and low-grade carcinoid tumors. Mixed neuroendocrine/non-neuroendocrine neoplasms are the most common. Often the diagnosis occurs randomly on endoscopic examination. Circulating markers, functional combined with conventional imaging contributes to the diagnosis and management. Treatment depends on type, grade and stage of the tumor.

Primary neuroendocrine neoplasm of the esophagus - Report of 14 cases from a single institute and review of the literature

BACKGROUND:

Most prevalent esophageal neoplasm is squamous cell carcinoma and adenocarcinoma. Other tumors are uncommon and poorly studied. Primary neuroendocrine esophageal neoplasm is a rare carcinoma and most of its therapy management is based on lung neuroendocrine studies. Neuroendocrine tumors can be clustered in the following subtypes: high grade (small cell carcinoma or large cell carcinoma) and low grade (carcinoids).

OBJECTIVE:

The present study aims to assess clinical and pathological neuroendocrine esophageal tumors in a single oncologic center.

METHODS:

A retrospective analysis of patients and review of the literatures was performed.

RESULTS:

Fourteen patients were identified as neuroendocrine tumors, 11 male and 3 female patients. Mean age was 67.3 years old. Ten patients were classified as small cell, 3 as large cell and 1 as carcinoid. Four patients presented squamous cell carcinoma simultaneously and 1 also presented adenocarcinoma. Main sites of metastasis were liver, peritoneum, lung and bones. Most patients died before 2 years of follow-up. Patient with longer survival died at 35 months after diagnosis.

CONCLUSION:

Neuroendocrine esophageal tumors are rare; affect mainly men in their sixties or seventies. High grade tumors can be mixed to other subtypes neoplasms, such as adenocarcinoma and squamous cell carcinoma. Most of these patients have poor overall survival rates.

Spontaneous intramural hematoma of the esophagus

Spontaneous intramural hematoma of the esophagus (SIHE) is a rare condition, usually presenting with severe acute chest pain. Vomiting, dysphagia, odynophagia, and hematemesis may appear later. We herein report a case of this disease in a patient treated with low doses of aspirin, and review the literature for possible etiologies for this condition. In addition, we compare the utility of the various diagnostic modalities in this uncommon condition.
