The Role of Patient Awareness and Knowledge in Developing Secondary Lymphedema after Breast and Gynecologic Cancer Surgery.

Background: This study aimed to compare the effects of awareness and knowledge on demographic and clinical factors in patients with breast cancer-related lymphedema (BCRL) and gynecologic cancer-related lymphedema (GCRL) in the oncologic rehabilitation setting. Methods and Results: A total of 506 female patients with upper or lower extremity lymphedema, were evaluated for lymphedema education in their postoperative period. Only 74 survivors (25%) with BCRL and 34 survivors (16.83%) with GCRL reported that they had received information about lymphedema by physicians/primary health care providers. In breast cancer survivors, the time of diagnostic delay for lymphedema was shorter in the informed group (p < 0.001), and there was a higher rate of cellulite attacks in uninformed patients (p = 0.021). Duration between surgery and lymphedema was longer and duration of diagnostic delay for lymphedema was shorter in the informed group than uninformed group in gynecologic cancer survivors (p = 0.019, p < 0.001). There was a higher rate of cellulite history in the uninformed patients than informed patients in gynecologic cancer survivors (p < 0.001). In gynecologic cancer survivors who were educated about lymphedema were at an earlier stage than noneducated patients (p = 0.024). Conclusion: The rate of awareness about lymphedema among patients with a history of surgery for gynecologic malignancies is lower compared with those for breast cancer. In female cancer survivors, awareness and knowledge about lymphedema may lead to a later onset of lymphedema, lower lymphedema grades, and fewer infection.
