Metastasis of melanoma in non-sentinel nodes in patients with metastatic sentinel node. Can we avoid complementary lymphadenectomy?

Background: Lymph mapping with sentinel node biopsy is the standard procedure for lymph node staging in patients with cutaneous melanoma with a tumor thickness of 1 mm or greater. Patients who have metastases in sentinel node must undergo complementary lymphadenectomy; however, it has not been shown to improve survival.

Objective: To know the prevalence in our setting of metastases in the product of complementary lymphadenectomy in patients with metastatic sentinel node.

Chest tomography for COVID-19 screening in head and neck cancer elective surgery. Is it enough?

Introduction: Head and neck cancer patients are at high risk of SARS-CoV-2 infection; surgery in them involves risk for patients, surgeons, health personnel, medical institutions and society, since it is associated with prolonged and inadvertent production of aerosols and emergency procedures that facilitate the breach of protective measures by health personnel.

Objective: To find out if pulmonary tomographic findings are sufficient to preoperatively identify patients with COVID-19.

Methods: Retrospective, cross-sectional, analytical study of patients with cervical-facial neoplasms who were candidates for surgery, preoperatively evaluated by simple chest computed tomography based on the CO-RADS classification.
