A Rare Case of Complete-Immunotherapy-Responsive Metastatic Non-Small Cell Lung Cancer with Long Lasting Progression-Free Survival: A Case Report.

Background and introduction: Lung cancer is a prevalent and deadly disease globally. Non-small cell lung cancer (NSCLC) is the most common subtype, comprising 85% of cases. Case report: A 65-year-old male ex-smoker presented to our facility with a nocturnal cough. Various investigations revealed that he had metastatic NSCLC, for which he underwent chemotherapy with cisplatin and gemcitabine, followed by immunotherapy with Nivolumab. He achieved a complete response to the therapy and has remained free from recurrence for over 7 years since the initial diagnosis. Discussion and Conclusions: The treatment of metastatic NSCLC remains a significant therapeutic challenge, but the implementation of new therapeutic techniques has expanded the possibilities of achieving complete and durable eradication of the disease.
