Characteristics of lymphoedema, in particular midline lymphoedema, after treatment for prostate cancer: a retrospective study.

BACKGROUND

Patients undergoing treatment for prostate cancer may develop lymphoedema of the midline region. This has a substantial impact on a patient's quality of life and its diagnosis is often delayed or missed. Therefore, the purpose of this study is to compare the characteristics of patients with leg and midline lymphoedema to patients with only leg lymphoedema.

METHODS

We retrospectively collected patient-, cancer-, lymphoedema- and lymphoedema treatment-related data of 109 men with lymphoedema after treatment for prostate cancer. First, 42 characteristics were compared between both groups. Second, factors predicting presence of midline lymphoedema were explored by multivariable analyses.

RESULTS

The mean age of the patients with lymphoedema was 68 ( ±7) years and mean BMI is 28 (±4) kg/m. Median duration of lymphoedema before the first consultation was 27 (9;55) months. Based on univariable analyses, patients with leg and midline lymphoedema had more frequently upper leg lymphoedema (89% (31/35) vs. 69% (51/74), p = 0.026), skin fibrosis (34% (12/35) vs. 16% (12/74), p = 0.034) and lymphatic reconstructive surgery (9% (3/35) vs. 0% (0/71), p = 0.020) than patients with only leg lymphoedema. Additionally, patients with leg and midline lymphoedema reported less frequently lower leg lymphoedema (77% (27/35) vs. 95% (70/74), p = 0.007). Based on the multivariable analysis, not having lower leg lymphoedema, skin fibrosis, performing self-bandaging and self-manual lymphatic drainage appear to be predictors for having midline lymphoedema.

CONCLUSIONS

If patients with lymphoedema after prostate cancer do not have lower leg lymphoedema, have skin fibrosis, perform self-bandaging or self-manual lymphatic drainage, they possibly have midline lymphoedema.
