• dc.description.abstract Purpose: Proviral integration site for Moloney murine leukemia virus (PIMs) are proto-oncogenes encoding serine/threonine kinases that phosphorylate a variety of substrates involved in the regulation of cellular processes. Elevated expression of PIM-1 has been associated with poor prognosis in several types of cancer. There are no studies that have analyzed the response to radiotherapy in patients with head and neck squamous cell carcinoma (HNSCC) according to the expression of PIM-1. The aim of our study was to analyze the relationship between the transcriptional expression of PIM-1 and local response to radiotherapy in HNSCC patients. Methods: We determined the transcriptional expression of PIM-1 in 135 HNSCC patients treated with radiotherapy, including patients treated with chemoradiotherapy (n = 65) and bioradiotherapy (n = 15). Results: During the follow-up, 48 patients (35.6%) had a local recurrence of the tumor. Patients with local recurrence had a higher level of PIM-1 expression than those who achieved local control of the disease (P = 0.017). Five-year local recurrence-free survival for patients with a high expression of PIM-1 (n = 43) was 44.6% (95% CI 29.2-60.0%), and for patients with low expression (n = 92) it was 71.9% (95% CI 62.5-81.3%) (P = 0.007). According to the results of multivariate analysis, patients with a high PIM-1 expression had a 2.2-fold increased risk of local recurrence (95% CI 1.22-4.10, P = 0.009). Conclusion: Patients with elevated transcriptional expression levels of PIM-1 had a significantly higher risk of local recurrence after radiotherapy.
