Superior Sulcus Tumors: Early Detection Is the Key

A superior sulcus or Pancoast tumor is located in the right or left apex of the lung. There is typically a delay in diagnosis because classic signs and symptoms associated with other lung cancers are absent. The initial symptoms are usually related to tumor impingement on structures in the thoracic inlet. The nurse practitioner needs to have a high index of suspicion to diagnose a Pancoast tumor at an early stage.
