ABSTRACT
Breast cancer-related lymphedema (BCRL) is characterized by arm swelling, pain, and discomfort, reducing the quality of life (QoL) of affected individuals. BRCL is caused via the blockage or disruption of the lymphatic vessels following cancer treatments, leading to an accumulation of fluid in the affected arm. While current BCRL rehabilitation treatments seek to reduce arm swelling, our study aimed to examine the impact of both the magnitude of lymphedema (ΔVolume) and arm disability on three dimensions of QoL: social, physical, and psychological. Using the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and the Upper Limb Lymphedema 27 questionnaire (ULL) in a group of 30 patients, we found that the magnitude of lymphedema (ΔVolume) was associated with the social dimension of QoL (r = 0.37, p = 0.041), but not with other dimensions. On the other hand, arm disability was associated with all evaluated dimensions of QoL (social, physical, and psychological: p < 0.001, p = 0.019, and p = 0.050 (borderline), respectively). These findings suggest that BCRL rehabilitation strategies should not only aim to reduce the magnitude of lymphedema but should also seek to improve or preserve arm functionality to enhance the QoL of BCRL patients.

Este estudo objetivou analisar, por meio de uma revisão sistemática da literatura, a influência da reconstrução imediata na prevalência de linfedema após mastectomia em pacientes portadoras de câncer de mama. Foram analisados os mais relevantes estudos publicados originalmente em qualquer idioma até agosto de 2018, indexados às bases de dados US National Library of Medicine, Cochrane Central Register of Controlled Trials, Web of Science e Scientific Electronic Library Online. A amostra foi composta por 10 publicações que se adequaram aos critérios de inclusão e exclusão estabelecidos, incluindo 2.425 pacientes submetidas a apenas mastectomia e 2.772 pacientes submetidas à mastectomia associada à reconstrução imediata da mama. A prevalência de linfedema foi 20,95% nas pacientes submetidas a apenas mastectomia (n = 508) e de 5,23% nas pacientes submetidas à mastectomia associada à reconstrução imediata (n = 145), havendo diferença estatisticamente significativa (p < 0,001). Concluiu-se que a mastectomia associada à reconstrução imediata influencia positivamente o prognóstico das pacientes portadoras de câncer de mama, proporcionando um índice significativamente menor de linfedema, quando comparada à realização de apenas mastectomia.
This study aimed to analyze, through systematic review of literature, the influence of immediate reconstruction on the prevalence of lymphedema after mastectomy, in women living with breast cancer. The analysis considered the most relevant studies originally published, in any language, up to August 2018, indexed on the databases of the US National Library of Medicine, Cochrane Central Register of Controlled Trials, Web of Science, and Scientific Electronic Library Online. The sample comprised 10 publications that met the established criteria for inclusion and exclusion, including 2,425 patients who were subjected to mastectomy alone, and 2,772 patients who were subjected to mastectomy associated with immediate reconstruction of the breast. The prevalence of lymphedema was 20.95% in patients who had been subjected to mastectomy alone (n = 508), and 5.23% among those patients who were subjected to mastectomy associated with immediate reconstruction of the breast (n = 145), the difference being statistically significant (p < 0.001). We concluded that mastectomy, when associated with immediate breast reconstruction, has a positive influence on the prognosis of patients living with breast cancer, thereby providing a much lower rate of lymphedema when compared with mastectomy alone.
