Objective
The innovation of novel systemic chemo/immunotherapy for metastatic head and neck cancer might contribute to prognostic improvement. We aimed to clarify the recent characteristics and outcomes of pulmonary metastasectomy for head and neck cancer.
Methods
Twenty-five patients who underwent pulmonary metastasectomy from January 2011 to December 2016 were included. The clinicopathological factors and survival were assessed by retrospective chart reviews.
Results
The median follow-up period was 39 months (range, 7–94 months). The median age was 66 years (range, 20–89 years), and 23 males were included. The primary tumor locations were as follows: pharynx (n = 12), nasal/paranasal cavity (n = 5), larynx (n = 4), and others (n = 4). The 5-year overall survival rate was 49%. In the univariate analysis, a history of local recurrence before pulmonary metastasis was an independent predictor of a poor prognosis. In 90% of patients with recurrence after pulmonary metastasectomy, the site of recurrence was the lung. Eight patients achieved long-term survival without any evidence of recurrence (median: 45 months). Molecular targeting chemotherapy and immune-checkpoint inhibitors were used in five patients with systemic recurrence after pulmonary metastasectomy, leading to preferable survival.
Conclusions
In the current era of advances in systemic chemotherapy and immunotherapy, surgical indication has not changed for resectable pulmonary metastases and selected patients can still benefit from pulmonary metastasectomy. Further investigation is needed to clarify the significance of systemic therapy in patients with pulmonary metastasis of head and neck cancer.
