Neoadjuvant immunochemotherapy followed by ex situ lung auto‐transplant (Oto procedure) for central lung cancer: A case report with literature review

Abstract

AbstractSleeve and double‐sleeve lobectomies are lung‐sparing techniques for treating central lung cancers. However, if the tumour extends to involve the bronchi and vessels, lung auto‐transplantation may be an alternative to pneumonectomy. Neoadjuvant therapy after surgery is the most common strategy for patients with extensive central lung cancer. Herein, we report a case of central lung cancer in a patient who underwent immunochemotherapy as neoadjuvant therapy following lung auto‐transplantation. A 68‐year‐old man with stage IIIA non‐small cell lung cancer and left upper lobe squamous cell carcinoma underwent neoadjuvant immunochemotherapy. Following partial regression, a multidisciplinary team decided on a back‐table procedure with auto‐lung transplantation after pneumonectomy to preserve pulmonary function. The patient had an uneventful recovery and was discharged after three weeks with no residual tumour or lymph node metastases. Lung auto‐transplantation can be successfully performed in non‐lung transplantation centres, potentially broadening treatment options for patients with central lung cancer.
