Primary Pulmonary Lymphoepithelioma-like Carcinoma: A Case Report Utilizing Camrelizumab and Anlotinib for Prolonged Survival.

Background: Primary Pulmonary Lymphoepithelioma-like Carcinoma (PPLELC) is a rare form of cancer for which no standard treatment has been established to date. Patients with advanced-stage PPLELC generally have a poor prognosis with overall survival of 22.7 months.

Case Presentation: Here, we report a case of advanced primary pulmonary lymphoepithelioma-like carcinoma. Initially, the patient underwent a first-line (GP) and a second-line (DP) of chemotherapy, which provided temporary relief but resulted in varying degrees of myelosuppression. When the disease progressed again, we administered a third-line treatment consisting of camrelizumab combined with anlotinib.

Result: This resulted in a progression-free survival of over 26 months without significant toxic side effects.

Conclusion: Our findings suggest that combining camrelizumab and anlotinib could lead to a long progressionfree survival in patients with advanced PPLELC.
