ObjectivesTo explore men´s onset and burden of lower limb lymphedema (LLL) after radical prostatectomy (RP) with pelvic lymph node dissection.
Patients and methodsA cross-sectional survey-based study was conducted nation-wide and web-based in Germany. Part 1 included 15 multidisciplinary compiled questions with three questions from Short Form 12 Health Survey (SF-12) and WHO activity recommendation, part 2 the validated German Lymph-ICF-Questionnaire (Lymph-ICF-LL). Subgroup comparisons and simple regression analyses were used to identify factors associated with therapy and burden of LLL, followed by multiple regression analyses to explain variance in impairment in the patients' daily life. Results 54 patients completed the survey. Median time of LLL-onset was reported with 2.0 (0.5-9.75) months after RP. 19 patients (35.2%) reported bilateral lymphedema, 28 (51.9%) the use of individually tted compression stockings (CS), 25 (46.3%) of manual lymphatic drainage (LD) and 26 (48.1%) complete regression.The Lymph-ICF-LL revealed a higher total burden for patients with an active LLL compared to complete regression (total score: 25.5 vs. 11.9, p=0.01) specially for "physical function" (28.3 vs. 12.9, p=0.004) and "mental function" (26.2 vs. 6.7, p<0.001). In multiple linear regression analysis, a higher BMI (β=0.28), lower subjective general health (β=-0.48) and active lymphedema (β =0.28) were signi cant predictors of higher reported impairments in the Lymph-ICF-LL, accounting for 45.4% of variance.
ConclusionMen with LLL after RP with PLND report a signi cant burden in daily life. Bbasic therapy needs to be offered early. Postoperative onset of LLL is variable, which should be considered when assessing complications after RP.
