Background:Esophageal squamous cell carcinoma is an aggressive neoplasia that requires a multidisciplinary treatment in which survival and prognosis are still not satisfactory. The complete pathologic response to neoadjuvant chemotherapy and radiotherapy is considered a good prognosis factor, and esophagectomy is indicated. Aim:Survival analysis of cases with pathologic complete response (ypT0 ypN0) to neoadjuvant chemotherapy and/or radiotherapy, submmitted to esophagectomy. Methods:Between 1983-2014, 222 esophagectomies were performed, and 177 were conducted to neoadjuvant treatment. In 34 patients the pathologic response was considered complete. Medical records of the patients were retrospectively reviewed regarding type of chemotherapy applied, amount of radiotherapy, interval between the neoadjuvant therapy and the surgery, body mass index; postoperative complications; hospital admission time and survival. Results:The average age was 55.8 years. Twenty-five patients were subjected to chemotherapy and radiotherapy, and nine to neoadjuvant radiotherapy. The total radiation dose ranged from 4400 until 5400 cGy. The chemotherapy was performed with 5FU, cisplatin, and carbotaxol, concomitantly with the radiotherapy. The esophagectomy was transmediastinal, followed by the cervical esophagogastroplasty performed on a average of 49.4 days after the neoadjuvant therapy. The hospital admission time was an average of 14.8 days. During the follow-up period, 52% of the patients submitted to radiotherapy and chemotherapy were disease-free, with 23.6% of them presenting more than five years survival. Conclusions:The neoadjuvant treatment followed by esophagectomy in patients with pathologic complete response is beneficial for the survival of patients with esophageal squamous cell carcinoma.
Introdução. O câncer de esôfago apresenta alta taxa de mortalidade mesmo após a ressecção com intenção curativa, sendo a sobrevida em 5 anos raramente superior a 25%. Assim sendo, estratégias de quimioradioterapia neoadjuvante foram aplicadas em uma tentativa de melhorar a sobrevida de pacientes com câncer esofágico localmente avançado. No entanto, os pacientes apresentam respostas variáveis à quimioradioterapia. Tem-se observado que pacientes com resposta patológica completa ao tratamento neoadjuvante evoluem com maior sobrevida global, além de maior sobrevida livre de doença em comparação àqueles com resposta patológica incompleta. Objetivo. O objetivo deste estudo é comparar os resultados entre os pacientes portadores de carcinoma epidermóide do esôfago não-respondedores e os respondedores submetidos a quimioradioterapia neoadjuvante seguidos de esofagectomia. Método. Estudo retrospectivo de prontuários médicos de pacientes tratados cirurgicamente de carcinoma epidermóide do esôfago no período de 2005 a 2012. Critérios de inclusão: tipo histológico carcinoma epidermóide, quimioradioterapia neoadjuvante. Critérios de exclusão: tipo histológico adenocarcinoma, ausência de terapia neoadjuvante, prontuários incompletos ou não localizados. Resultados. Foram avaliados 62 pacientes (N) tratados cirurgicamente de carcinoma epidermóide do esôfago no período de 2005 a 2012. Todos os pacientes foram submetidos a quimioradioterapia neoadjuvante mas apenas 22 (35,4%) pacientes apresentaram resposta patológica completa definida como ausência de células neoplásicas no estudo anatomopatológico da peça cirúrgica. Conclusão. O tratamento neoadjuvante seguido de esofagectomia nos pacientes com resposta patológica completa oferece benefícios na sobrevida de portadores de carcinoma epidermóide do esôfago conforme sugerido na literatura médica.
