Background
Sporadic lymphangioleiomyomatosis (LAM) is a rare form of diffuse parenchymal lung disease. PD-1 blocking antibodies constitute an essential treatment option for advanced non-small-cell lung cancer (NSCLC). The effect of immune checkpoint inhibitors in lymphangioleiomyomatosis patients with non-small cell lung cancer is unknown: concomitant symptomatic interstitial lung disease or the use of immunosuppressors was a key exclusion criterion in the original studies of immune checkpoint inhibitors, especially regarding the risk of interstitial lung disease exacerbation.
Case presentation
A 48-year-old female, active smoker (36 pack-years), diagnosed with sporadic LAM since 2004 suffered from metastatic adenocarcinoma of the lung. Third-line therapy with nivolumab was started in 2015, with a major partial response. Due to pulmonary function alterations, sirolimus was also reinitiated in 2017 in conjunction with nivolumab, without any undesirable effects and a major partial response continuing up to May 2018.
Conclusions
This case highlights the safe and effective use of nivolumab for managing metastatic lung adenocarcinoma that occurred in a patient with sporadic LAM. In the current case, immunotherapy proved highly successful in managing the NSCLC tumor that occurred upon LAM follow-up, with both a significantly prolonged partial response and acceptable safety profile.
