Distally Prophylactic Lymphaticovenular Anastomoses after Axillary or Inguinal Complete Lymph Node Dissection Followed by Radiotherapy: A Case Series

Primary Lymphovenous Anastomosis After Extended Soft Tissue Resection in the Medial Thigh for Reduction of Lymphocele and Lymphedema

INTRODUCTION

Postoperative chronic lymphocele and lymphedema represent severe burdens for soft tissue sarcoma patients who are already physically handicapped after an extensive surgery and a long recovery time. Incidences are high in the upper medial thigh. We have shifted our focus to lymphedema and lymphocele risk reduction with immediate lymphovenous anastomosis (LVA) after sarcoma resection.

METHODS

We performed immediate lymphatic reconstruction in 11 patients after soft tissue sarcoma resection in the upper medial thigh. The postoperative course was followed up closely, and postoperative occurrence of lymphocele and lymphedema was clinically assessed. A literature search outlining the latest clinical data, current treatment strategy landscape, and their application into clinical practice was added to the investigation.

RESULTS

A total of 19 LVA and 2 lympho-lymphatic anastomoses were performed in 11 patients immediately after tumor resection in an end-to-end manner. We found a postoperative lymphedema rate of 36% and a postoperative lymphocele rate of 27%. Mean follow-up time was 17 months. Average tumor volume was 749 cc. Our literature search yielded 27 articles reporting on immediate LVA in cancer patients. Incidences of secondary lymphedema after LVA for lymphedema prevention vary between 0% and 31.1%. Lymphocele prevention with LVA is poorly studied in sarcoma patients.

CONCLUSION

Immediate lymphatic reconstruction improved the overall postoperative course of our patients. The current literature does not serve with high-quality studies about primary LVA preventing lymphedema and lymphocele formation. We conclude that this technique should be seen as an additional concept to achieve overall better postoperative outcomes in these challenging surgical settings. We strongly recommend to either anastomose or ligate severed lymphatics under the microscope primarily after sarcoma resection in the upper medial thigh area.

Lymphedema is a complex clinical condition that appears as a result of the failure of the lymphatic system function, and it is characterized by edema, fibrosis, and adipose deposition [...].

Prevention of Breast Cancer-Related Lymphedema: An Up-to-Date Systematic Review of Different Surgical Approaches

Breast cancer-related lymphedema (BCRL) affects approximately 20% of women after breast cancer therapy. Advances in treatment have increased the life expectancy; thus, the prevalence of BCRL will continue to rise with the number of cancer survivors, hence the need to develop strategies to prevent this condition. We provide a systematic review of the literature on the primary prevention of BCRL by prophylactic lymphatic surgery (PLS). Between June and August 2022, we conducted a search of PubMed, Google Scholar and Cochrane. In the end, a total of eighteen papers were selected. The eleven studies without a control group reported only 15 of 342 patients who developed lymphedema at least six months after PLS (4.59%). The seven studies with a control group included 569 patients, 328 cases and 241 controls. Among the cases, 36 (10%) developed lymphedema. In contrast, the incidence of lymphedema in the controls was 40% (98 of 241 patients). The formulation of definite recommendations in favor of PLS is hindered by low-quality studies. There is no consensus on which technique should be preferred, nor on whether adjuvant radiotherapy might affect the efficacy of PLS. Randomized controlled trials are mandatory to conceive evidence-based recommendations.
