Abstract

Breast cancer is the most common malignant neoplasm in the female population. However, stomach is a rare site for metastasis, and can show up many years after initial diagnosis and treatment of the primary tumor. Analyze a case series of this tumor and propose measures that can diagnose it with more precocity. Were analyzed 12 patients with secondary gastric tumors. Immunohistochemistry has demonstrated that primary tumor was breast cancer. We retrieved information of age, histological type, interval between diagnosis of the primary breast cancer and its metastases, immunohistochemistry results, treatment and survival. The mean age was 71.3 years (ranging 40-86). Ten cases had already been underwent mastectomy in the moment of the diagnosis of gastric metastasis. Two patients had diagnosis of both primary and secondary tumors concomitantly. At average, diagnosis of gastric metastasis was seven years after diagnosis of primary breast cancer (ranging 0-13). Besides, nine cases had also metastases in other organs, being bones the most affected ones. Immunohistochemistry of the metastases has shown positivity for CK7 antibody in 83.34%, estrogen receptor in 91.67%, progesterone receptor in 66.67% and AE1AE3 antibody in 75%, considering all 12 cases. Moreover, CK20 was absent significantly (66.67%). The positivity of BRST2 marker did not present statistical significance (41.67%). Eight cases were treated with chemotherapy associated or not with hormonal blockade. Surgical treatment of gastric metastasis was performed in four cases: three of them with total gastrectomy and one with distal gastrectomy. Follow-up has shown a mean survival of 14.58 months after diagnosis of metastasis, with only two patients still alive. Patients with a history of breast cancer presenting endoscopic diagnosis of gastric cancer it is necessary to consider the possibility of gastric metastasis of breast cancer. The confirmation is by immunohistochemistry and gastrectomy should be oriented in the absence of other secondary involvement and control of the primary lesion. A neoplasia de mama é o tumor maligno mais comum na população feminina tendo o trato gastrointestinal, e mais especificamente o estômago, como local incomum para metástases. Analisar uma série de casos com esse tumor e propor medidas que possam diagnosticá-lo com maior precocidade. Foram analisados retrospectivamente 12 pacientes com diagnóstico de neoplasia gástrica secundária a câncer de mama, confirmado por biópsia e imunoistoquímica. Foram analisados idade do diagnóstico, tipo histológico do tumor primário, intervalo de tempo entre o diagnóstico do tumor e a metástase, tratamento e sobrevida. A idade média foi de 71,3 anos (40-86 anos). Em média, o diagnóstico da metástase gástrica foi de sete anos após o diagnóstico da lesão primaria (0-13 anos). Nove casos tiveram metástases em outros órgãos, sendo os ossos os locais mais acometidos. Evidenciou-se positividade de anticorpo CK7 em 90,9% casos, receptor de estrógeno em 91,67%, receptor de progesterona em 66,67% e BRST2 em 41,67%. A ausência de CK20 foi de 88,89%. Oito casos foram tratados com quimioterapia associada ou não ao bloqueio hormonal e em quatro foi indicada ressecção cirúrgica sendo em três gastrectomia total e em um caso gastrectomia subtotal. A sobrevida média foi de 14,58 meses. Em doentes com história prévia de câncer de mama apresentando diagnóstico endoscópico de neoplasia gástrica, é necessário considerar a possibilidade de metástase. A confirmação é feita por estudo imunoistoquímico e a gastrectomia deve ser orientada diante da ausência de outros locais de acometimento secundário e controle da lesão primária.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 July 2016.
All research outputs
#14,030,881
of 15,911,777 outputs
Outputs from ABCD. Arquivos Brasileiros de Cirurgia Digestiva (São Paulo)
#82
of 140 outputs
Outputs of similar age
#223,033
of 267,038 outputs
Outputs of similar age from ABCD. Arquivos Brasileiros de Cirurgia Digestiva (São Paulo)
#1
of 1 outputs
Altmetric has tracked 15,911,777 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 140 research outputs from this source. They receive a mean Attention Score of 1.6. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,038 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
