Lymphaticovenular anastomosis for breast cancer-related upper extremity lymphedema: a literature review.

ABSTRACT: Breast cancer-related lymphedema is a long-term condition that affects almost half of breast cancer survivors. Clinical studies have looked at the benefits of lymphaticovenular anastomosis (LVA) for the treatment of upper extremities lymphedema after breast cancer, however, there is still controversy if it improves lymphedema. This study aimed to analyze the studies and outcomes related to LVA for breast cancer-related lymphedema. A PubMed/Medline search was performed using "lymphovenous bypass", "upper extremity lymphedema", "arm lymphedema after breast cancer treatment", and "lymphaticovenular anastomosis" as key words. Only English articles reporting outcomes after LVA were included. We found 22 articles that met the inclusion criteria. Positive outcomes were found in 21 studies with an objective volume reduction and subjective symptoms relief after LVA. This literature review concluded that LVA has demonstrated a significant decrease in upper extremity volumes and an improvement in subjectively reporting symptoms in breast cancer-related lymphedema patients.

Project description:Lymphedema can be a debilitating condition, causing a great decrease in a person's quality of life (QoL). Treatment with lymphaticovenular anastomosis (LVA), in which an anastomosis is created between the lymphatic and venous system, may attenuate lymphedema symptoms and reduce swelling. In this study, we share the results using LVA to treat breast cancer-related lymphedema (BCRL) at our institution.Patients were eligible for inclusion if they suffered from unilateral BCRL, if functional lymphatics were available, if compression therapy was used for at least 6 months, and if the follow-up was 12 months at minimum. Lymph vessel functionality was assessed preoperatively using indocyanine green (ICG). During surgery, 1-3 anastomoses were created and shunt patency was confirmed using ICG. Arm volumes were measured before surgery and at 6- and 12-month follow-up. QoL was measured before surgery and at 6-month follow-up. Arm volume differences between the healthy arm and affected arm were compared between the time points.Twenty-nine consecutive female patients with unilateral BCRL were included. The preoperative mean difference in arm volumes was 701 ± 435 ml (36.9%). This was reduced to 496 ± 302 ml (24.7%) at 6-month follow-up (p = 0.00). At 12-month follow-up, the mean difference in arm volume was 467 ± 303 ml (23.5%) (p = 0.02). The overall perceived QoL was increased from 5.8 ± 1.1 to 7.4 ± 0.7 (p = 0.00). The functionality score decreased from 2.2 to 1.8 (p = 0.00), the appearance score decreased from 2.6 to 1.9 (p = 0.00), the symptoms score decreased from 2.8 to 1.8 (p = 0.00), and the mood score decreased from 2.7 to 1.5 (p = 0.00). Fifteen patients (53.6%) were able to discontinue the use of compression garment.Treatment with LVAs is effective in reducing arm volume difference in patients suffering from BCRL. Although no complete reduction of the edema was achieved at 12-month follow-up, the procedure significantly increased the patients' QoL.

Project description:BackgroundThe recent increase in the number of patients with lower extremities lymphedema and the development of microsurgery techniques have led to a rise in lymphedema treatment. Vascularized omental lymph node transfer (VOLT), an emerging treatment modality for extremity lymphedema, has shown its unique advantages in reconstructing lymphatic circulation and absorbing exudated lymphatic fluid. Patients who underwent radical tumor resection with/without radiation therapy treatment often present with impairment or degeneration of the inguinal lymph nodes. For such cases, VOLT could provide adequate lymph nodes and tissue to absorb edema fluid in these areas. Therefore, we analyzed the operative outcomes of VOLT under the guidance of magnetic resonance lymphangiography (MRL) in this study, as this individualized and precise surgical procedure could benefit patients and improve their quality of life.MethodsFrom November 2021 to September 2022, a total of 14 patients' 19 legs with extremity lymphedema underwent a VOLT with or without lymphaticovenous anastomosis (LVA). Outcomes, including circumference reduction rates, preoperative and postoperative MRL results, and other complications, were analyzed.ResultsThe mean follow-up period was 8.86±1.41 months (range, 7-11 months). The mean circumference reduction rates {circumference reduction rate (%) = [1 - (postoperative affected limb - healthy limb)/(preoperative affected limb - healthy limb)] × 100%} of different planes (i.e., ankle, 10 cm above the knee, 10 cm below the knee, 10 cm above the ankle, and 20 cm above the knee) were 15.64%±40.08%, 11.79%±30.69%, 20.25%±24.94%, 7.73%±30.05%, -1.517%±16.75%. Notably, one patient had multi-drug-resistant gram-negative infections, which resulted in the loss of three flaps. The postoperative MRL showed improved lymphatic drainage and lower extremity volume in the remaining 13 cases.ConclusionsThe precision evaluation of inguinal lymph nodes and lower extremities lymphatic system through MRL using VOLT can provide surgeons with a comprehensive understanding and reliable evidence for the treatment of cancer-related lower extremity lymphedema.
