“…Importantly, if the primary cancers are discordant in tumor biology including histopathologic classification, mutation status, hormone receptor status, and HER2 receptor status, metastatic cross-seeding may lead to increased intratumoral heterogeneity, adding another layer of complexity when choosing the optimal treatment plan. A study of the pathological profiles of 55 SBBC patients found estrogen receptor status, progesterone receptor status, and HER2 status discordance rates between the two primary tumours of 15%, 11%, and 8%, respectively 26 . With these factors being established biomarkers for expected treatment response and prognosis, hormone receptor discordance in SBBC patients has been associated with increased rate of metastasis and higher mortality at 5 years 27, 28 .…”

“…Compreender os diversos fatores que contribuem para o desenvolvimento de tumor contralateral é importante para melhorar a seu curso clínico alterado, curso de tratamento exagerado e custos, prognóstico agravado comparado com tumor unilateral (KAPPIKERI; KRIPLANI, 2015). Iyer et al (2017) encontram em sua pesquisa -com uma amostragem de 10.848 pacientes com idade entre 21 e 74 anos -55 (0,5%) casos de SBBC na Índia, considerando -para este estudoos casos em que há a ocorrência de câncer na mama contralateral dentro de seis meses após o diagnóstico de câncer de mama primário.…”

“…Os fatores de risco para o desenvolvimento de câncer de mama primário contralateral foram investigados comparando os parâmetros histopatológicos do câncer de mama unilateral e o primeiro tumor dos cânceres bilaterais, enquanto as características bilaterais da doença foram determinadas comparando o câncer unilateral com o segundo tumor da doença bilateral e analisando ainda mais os sinais síncronos e tumores metacrônicos (IYER et al, 2017).…”
