Prognostic significance of basal versus superior segment in patients with completely resected lung adenocarcinoma in the lower lobe: Prognostic factors in lower lobe LC

Background Although the lower lobes of the lungs occupy half of the chest on both sides, the prognostic value of tumor location in lung cancer in the lower lobe has not been well demonstrated. This study investigated the prognostic value of tumor location (basal vs. superior) in patients with resected lung adenocarcinoma in the lower lobe.
