To the Editor: The morbidity of thoracic lesions is very high during the treatment of malignant hematological diseases, and tumor recurrence or invasion is common, in addition to infections. Percutaneous lung biopsy or bronchoscopy could result in severe hemoptysis, pneumothorax, or infection because of low platelets and hypoimmunity, and treatment is often ineffective due to the ambiguousdiagnosis.Evenwhenapatient isdiagnosedwith a fungal disease, it is difficult to eliminate the lesion with only antifungal medicine. Video-assisted thoracic surgery (VATS) is an important surgical procedure for major and minor lung resectionwith adequate pain relief and sedation in aminimally invasive setup, allowing thoracic procedures under spontaneous breathing.We report here a series of cases to evaluate the feasibility and safety of VATS for makingdiagnosesby lungbiopsyorpulmonary resections in the hematology department.
