Sobrevida de mulheres com câncer de mama que realizaram tratamento entre 2005 e 2015 em Campina Grande

Abstract

This study utilized the statistical technique of survival analysis to investigate the time between the start of treatment and remission of breast cancer, as well as the factors associated with this process in women treated at the Hospital da Fundação de Assistência da Paraíba in Campina Grande, Paraíba. The Weibull model was employed to analyze the remission data, revealing that the likelihood of remission increases as the length of hospital stay extends. Variable selection was conducted using the stepwise method, identifying the type of therapy, number of chemotherapy sessions, and number of hormone therapy sessions as the primary influencing factors. The results indicated that combined therapy prolongs hospitalization time by 48% compared to adjuvant therapy, while each additional session of chemotherapy and hormone therapy increases the time by approximately 3% and 1.7%, respectively. These findings contribute to the understanding of breast cancer treatment and may guide future clinical interventions and health policies.
