Long-term survival of a non-small cell lung cancer patient with EGFR-mutated brain metastases: a case report.


ABSTRACT:

Background

Lung cancer is the leading cause of cancer-related death worldwide. Up to 85% of lung cancer is non-small cell lung cancer (NSCLC) and most patients present with advanced disease at first diagnosis. Targeted therapy plays an important role in the treatment of advanced NSCLC. Epidermal growth factor receptor (EGFR) mutation is a predictive marker of sensitivity to EGFR tyrosine kinase inhibitors (TKIs). Patients with EGFR-mutated NSCLC are prone to developing central nervous system (CNS) metastasis and poor prognosis (4-6 months). Brain metastases (BMs) remain a tricky problem in NSCLC patients and impose a distinct challenge for clinicians.

Case description

This article details a patient with EGFR-mutated BMs accepting a series of treatments but without chemotherapy, resulting in significantly prolonged survival with overall survival (OS) over 8 years and improved clinical symptoms. The patient in our case received four lines of treatments and the progression-free survival (PFS) in each line were longer than the previously reported without exception. It is worth noting that the combination of osimertinib and bevacizumab used in the fourth-line therapy has a PFS of 31 months and has not progressed so far.

Conclusions

Our case demonstrates that it is possible to achieve long-term survival in advanced EGFR-mutated NSCLC with multiple BMs and systemic progression through a reasonable therapeutic schedule.
