Observation policy for sentinel node metastasis of melanoma: Comparative study with completion lymph node dissection in Japanese patients.

J Dermatol 2021 May 7. Epub 2021 May 7.

Division of Dermatology, Niigata Cancer Center Hospital, Niigata, Japan.

Based on the results of international multicenter randomized trials, completion lymph node dissection for patients with sentinel lymph node-positive melanoma is no longer routinely recommended. However, clinicians should take into consideration racial and medical resource differences when applying this evidence to clinical practice in Japan. To evaluate the clinical validity of the observation policy of omitting completion lymph node dissection, we retrospectively surveyed patients with sentinel lymph node-positive melanoma between 2002 and 2020 at Niigata Cancer Center Hospital.
