Early Diagnosis and Risk Factors for Lymphedema following Lymph Node Dissection for Gynecologic Cancer


Early Diagnosis and Risk Factors for Lymphedema following Lymph Node Dissection for Gynecologic Cancer.

**My only concern here is the way they reported one stat. In reporting that 50 individuals had dermal backflow (triggering swelling?). They weren't clear about this AND they reported all had symptoms go away within 3 months.  What that tells me (just a humble patient) is that these individual are very likely going to show up with lower limb LE during their life time.  The over all stats for gynecological cancer does in some cases, run about 50%. - Pat**

Abstract


BACKGROUND:

Although early diagnosis is important for selecting an effective surgical treatment for secondary lymphedema, an efficient screening test for detecting early-stage lymphedema has not yet been established. Serial changes of lymphatic function before and after lymph node dissection and risk factors for secondary lymphedema are important indicators.

METHODS:

A prospective cohort observational study was conducted with 100 consecutive gynecologic cancer patients who underwent pelvic lymph node dissection. Lymphatic function was assessed by noninvasive lymphography using indocyanine green fluorescence imaging on a routine schedule. Earliest findings after lymphadenectomy and risk factors for lower leg lymphedema were investigated.

RESULTS:

Atypical transient dermal backflow patterns were observed in an early postoperative period in 50 cases, all of which disappeared within 3 months. Of these patterns, the splash pattern was observed in 31 patients, of which five improved to normal following a natural course. In contrast, the stardust pattern was observed in 27 patients, and none had improved with conservative therapy. Postoperative radiotherapy was a significant risk factor for the stardust pattern.

CONCLUSIONS:

All patients who undergo lymphadenectomy for gynecologic malignancies should be examined for secondary lower extremity lymphedema by qualitative evaluation methods on a routine schedule to determine the earliest possible diagnosis. Because the splash pattern on indocyanine green lymphography is a reversible lymphatic disorder following a natural course, surgical treatments are not recommended. The decision regarding surgical treatment can be made after observing the stardust pattern.

CLINICAL QUESTION/LEVEL OF EVIDENCE:
