Surgical resection for persistent localized pulmonary fungal infection prior to allogeneic hematopoietic stem cell transplantation: Analysis of six cases.

OBJECTIVE

Although invasive fungal disease (IFD) is an important complication in allogeneic hematopoietic stem cell transplantation (HSCT), the clinical significance of surgery, including the role of surgical resection for persistent pulmonary fungal disease prior to allogeneic HSCT in the current era with a variety of available antifungal agents, is controversial. We investigated the role of surgical resection.

METHODS

We retrospectively investigated six patients who underwent surgical resection of suspected pulmonary fungal disease prior to allogeneic HSCT between April 2007 and June 2016 at our medical center.

RESULTS

We present six patients who underwent surgical resection of suspected pulmonary fungal disease prior to allogeneic HSCT. In our case series, three of four patients who were given a presurgical diagnosis of possible IFD were given a proven diagnosis after surgery, including two cases of invasive aspergillosis (IA) and one case of mucormycosis. All surgeries were performed by video-assisted thoracic surgery (VATS) for lobectomy without major complications. Recurrence of IFD was not observed after allogeneic HSCT in any of the six patients.

CONCLUSION

Our experience indicated that surgical resection of persistent localized pulmonary lesions of IFD before allogeneic HSCT was helpful for obtaining a definitive diagnosis and might be useful for reducing recurrence after HSCT.
