The Therapeutic Effects of Goreisan, a Traditional Japanese Herbal Medicine, on Lower-Limb Lymphedema after Lymphadenectomy in Gynecologic Malignancies: A Case Series Study.

ABSTRACT: Background:Lower-limb lymphedema (LLL) is a chronic and progressive complication of gynecologic cancer treatment, including pelvic lymphadenectomy. This study aims to investigate the therapeutic effect of goreisan, a traditional Japanese medicine, which has been used for hydrostatic modulation on patients with LLL. Methods:Patients diagnosed with LLL in our hospital in 2018 were included and principally treated with complex decongestive therapy (CDT), including elastic clothing and lymph drainage. The patients who received a combination therapy of CDT and goreisan (CDT-G group) were prescribed goreisan extract granules, with a dose of 7.5?g per os daily in three doses. Patients who were not prescribed goreisan received CDT alone (CDT group). The severity of lymphedema was evaluated by the estimated limb volume calculated by limb circumferences and the ratio of extracellular water (ECW) to total body water (TBW). Results:Nineteen women with LLL after pelvic lymphadenectomy were included in the study. The number of patients in the CDT and CDT-G groups was 8 and 11, respectively. There were no statistically significant differences between the CDT and CDT-G groups in terms of patient characteristics and severity of LLL before treatment. Reduction in ECW/TBW in the CDT-G group (in the whole body and the affected lower limb) after the intervention was significantly more remarkable than that in the CDT group. Conclusions:Goreisan-based Japanese herbal therapy may be effective in patients with LLL after retroperitoneal lymphadenectomy.

Project description:Lower limb lymphedema (LLL) is a chronic and incapacitating condition afflicting patients who undergo lymphadenectomy for gynecologic cancer. This study aimed to identify risk factors for LLL and to develop a prediction model for its occurrence.Pelvic lymphadenectomy (PLA) with or without para-aortic lymphadenectomy (PALA) was performed on 366 patients with gynecologic malignancies at Yaizu City Hospital between April 2002 and July 2014; we retrospectively analyzed 264 eligible patients. The intervals between surgery and diagnosis of LLL were calculated; the prevalence and risk factors were evaluated using the Kaplan-Meier and Cox proportional hazards methods. We developed a prediction model with which patients were scored and classified as low-risk or high-risk.The cumulative incidence of LLL was 23.1% at 1 year, 32.8% at 3 years, and 47.7% at 10 years post-surgery. LLL developed after a median 13.5 months. Using regression analysis, body mass index (BMI) ?25 kg/m2 (hazard ratio [HR], 1.616; 95% confidence interval [CI], 1.030-2.535), PLA + PALA (HR, 2.323; 95% CI, 1.126-4.794), postoperative radiation therapy (HR, 2.469; 95% CI, 1.148-5.310), and lymphocyst formation (HR, 1.718; 95% CI, 1.120-2.635) were found to be independently associated with LLL; age, type of cancer, number of lymph nodes, retroperitoneal suture, chemotherapy, lymph node metastasis, herbal medicine, self-management education, or infection were not associated with LLL. The predictive score was based on the 4 associated variables; patients were classified as high-risk (scores 3-6) and low-risk (scores 0-2). LLL incidence was significantly greater in the high-risk group than in the low-risk group (HR, 2.19; 95% CI, 1.440-3.324). The cumulative incidence at 5 years was 52.1% [95% CI, 42.9-62.1%] for the high-risk group and 28.9% [95% CI, 21.1-38.7%] for the low-risk group. The area under the receiver operator characteristics curve for the prediction model was 0.631 at 1 year, 0.632 at 3 years, 0.640 at 5 years, and 0.637 at 10 years.BMI ?25 kg/m2, PLA + PALA, lymphocyst formation, and postoperative radiation therapy are significant predictive factors for LLL. Our prediction model may be useful for identifying patients at risk of LLL following lymphadenectomy. Providing an intensive therapeutic strategy for high-risk patients may help reduce the incidence of LLL and conserve the quality of life.
