Ovarian Metastasis from Colorectal Adenocarcinoma
Metástase ovariana de adenocarcinoma colorretal
Abstract
Introduction Ovarian metastases of gastrointestinal origin, also called Krukenberg tumors, have a guarded prognosis. Physicians need to look for alternatives in diagnosis and treatment for this clinical condition in order to improve the outcome of the patients.
Objectives To report the experience of the authors in the treatment of these patients, and to perform a review of the literature on the epidemiology, clinical presentation, diagnosis, treatment, and prognosis for ovarian metastases from colorectal cancer.
Methods We collected clinical information regarding the patients treated for ovarian metastasis from colorectal adenocarcinoma at our coloproctology service, and performed a search on the PubMed database using the terms colorectal cancer, ovarian metastasis, Krukenberg tumor and surgery.
Conclusion Large abdominal tumors are the most frequent presentation of ovarian metastasis from colorectal cancer. The diagnosis is based on a histopathological analysis, levels of carcinoembryonic antigen (CEA) and cancer antigen 125 (CA-125), and immunohistochemical studies for the cytokeratin 20 (CK20), caudal-type homeobox 2 (CDX2) and vilina markers. Citoreductive surgical procedures are the most promising approach to treatment, with the highest impact on overall survival. The prognosis is negatively influenced by the extent of the metastasis, by citoreductive surgical procedures with persistence of macro- or microscopic foci of the disease, and by low scores on the general well-being index of the patient.
Resumo
Introdução As metástases ovarianas de tumores gastrointestinais, também chamadas de tumores de Krukenberg, são neoplasias de prognóstico reservado. Exigem conhecimento de alternativas diagnósticas e terapêuticas para garantir melhora da sobrevida das pacientes.
Objetivos Relatar a experiência dos autores no tratamento dessas pacientes, e fazer uma revisão da literatura sobre a epidemiologia, apresentação clínica, diagnóstico, tratamento e prognóstico das metástases ovarianas do câncer colorretal.
Métodos Foi realizada uma coleta de informações clínicas de pacientes tratados por metástases ovarianas de adenocarcinoma colorretal em nosso serviço de coloproctologia, em conjunto com uma pesquisa na base de dados PubMed com os termos colorectal cancer, ovarian metastasis, Krukenberg tumor, e surgery.
Conclusão Volumosas massas abdominais constituem a principal apresentação clínica da doença. As alternativas diagnósticas incluem a avaliação histopatológica, a identificação dos níveis de antígeno cárcino-embriônico (ACE) e de antígeno de câncer 125 (CA-125), e exame imunoistoquímico de espécimes cirúrgicos para os marcadores citoqueratina 20 (CK20), homeobox 2 do tipo caudal (CDX2), e vilina. O tratamento citorredutor completo demonstrou o maior impacto na sobrevida dos pacientes. O prognóstico é influenciado negativamente pela extensão da doença metastática, por cirurgia citorredutiva com persistência focos microscópicos ou macroscópicos da doença, e baixo escore de índice de bem-estar geral do paciente.
