ABSTRACT
Summary

Background:

to evaluate if time between surgery and the first adjuvant treatment (chemotherapy, radiotherapy or hormone therapy) in patients with breast cancer is a risk factor for lower overall survival (OS).

Method:

data from a five-year retrospective cohort study of all women diagnosed with invasive breast cancer at an academic oncology service were collected and analyzed.

Results:

three hundred forty-eight consecutive women were included. Time between surgery and the first adjuvant treatment was a risk factor for shorter overall survival (HR=1.3, 95CI 1.06-1.71, p=0.015), along with negative estrogen receptor, the presence of lymphovascular invasion and greater tumor size. A delay longer than 4 months between surgery and the first adjuvant treatment was also associated with shorter overall survival (cumulative survival of 80.9% for delays ≤ 4 months vs. 72.6% for delays > 4 months; p=0.041, log rank test).

Conclusion:

each month of delay between surgery and the first adjuvant treatment in women with invasive breast cancer increases the risk of death in 1.3-fold, and this effect is independent of all other well-established risk factors. Based on these results, we recommend further public strategies to decrease this interval.
RESUMO
Resumo

Objetivo:

avaliar se o tempo da cirurgia até o primeiro tratamento adjuvante (quimioterapia, radioterapia ou hormonioterapia) em pacientes com câncer de mama é um fator de risco para pior sobrevivência global (SG).

Métodos:

estudo retrospectivo em que foram coletados dados dos prontuários de todas as mulheres com câncer de mama invasivo, diagnosticadas entre janeiro de 2005 e dezembro de 2010, atendidas consecutivamente em um serviço acadêmico de oncologia.

Resultados:

foram incluídas 348 mulheres, com mediana de tempo entre a cirurgia e o primeiro tratamento adjuvante de 2 meses. A sobrevivência global foi pior entre as mulheres com maior tempo entre a cirurgia e o primeiro tratamento adjuvante. Após análise multivariada, essa variável permaneceu como fator de risco independente para SG, juntamente com receptor de estrógeno negativo, presença de invasão angiolinfática e maior tamanho tumoral.

Conclusão:

o tempo entre a cirurgia e o primeiro tratamento adjuvante é um fator de risco independente para a sobrevivência global de mulheres com câncer de mama invasivo.
