Prognostic factors in brain metastases from laryngeal squamous cell carcinoma: Case report and review

BACKGROUND: Brain metastases from laryngeal squamous cell carcinoma (SCC) are rare, and there are no standardized treatments. Here we reported on a case of brain metastasis from laryngeal SCC and performed a literature review on these cases. Moreover, by plotting Kaplan–Meier curves, we carried out a survival analysis to provide an estimation of overall survival (OS) and to find possible prognostic factors. CASE DESCRIPTION: A 65-year-old male was admitted to our department with a large left occipital lesion. Three years ago, the patient had undergone total laryngectomy with bilateral neck dissection with a diagnosis of a poor differentiated SCC. The occipital lesion was totally removed. A diagnosis of a brain metastasis from laryngeal SCC was made. The patient was submitted to adjuvant chemotherapy and radiation therapy. He is in good clinical conditions at 7-month follow-up with a still ongoing chemotherapy. From survival analysis, we have found that surgery and/or radiochemotherapy increase the OS of these patients compared with untreated cases. Moreover, Karnofsky performance status (KPS) score ≥70 and recursive partitioning analysis (RPA) classes I and II were associated with better OS in these patients. CONCLUSION: Brain metastases from laryngeal SCC are rare. This is the first study in which a survival analysis of these cases has been performed. Surgery and/or radio-chemotherapy increase the survival of these patients compared with untreated cases. Moreover, KPS score and RPA class affect the outcome of these patients.
