    Outcome of Elderly Nasopharyngeal Carcinoma Patients: A Single Center Study
    (2020) Basaran, Hamit; Cengiz, Mustafa; Yazici, Gozde; Ozdemir, Yurday; Suslu, Nilda; Gullu, Ibrahim H.; Ozyigit, Gokhan; 0000-0002-2218-2074; AAG-5629-2021
    Objective: This study aimed to assess the efficiency of radiotherapy and evaluate its outcomes for elderly (> 65 years) patients who have undergone treatment for nasopharyngeal carcinoma (NPC). Methods: Forty- five (male, 35; female, 10) elderly patients with a diagnosis of undifferentiated NPC who were treated at our institution between 1994 and 2012 were retrospectively evaluated. The primary endpoint was the relationship between the patients' characteristics and overall survival (OS); progression-free survival (PFS), locoregional progression-free survival (LR-PFS), and toxicity analysis were the secondary endpoints. Results: The patients had a median age of 74.2 years. At a median follow-up period of 64 months, the median OS, PFS, and LR-PFS were 45 (95% confidence interval [CI]: 5.887-84.113), 34 (95% CI: 0.0-70.504), and 45 (95% CI: 20.092-69908) months, respectively. The 2-, 3-, and 5-year OS rates were 61.5%, 53.1%, and 50.0%, respectively, and the 2-, 3-, and 5-year PFS rates were 57.6%, 46.8%, and 43.7%, respectively. Patients with T stage (T3-T4 vs.T1-T2) or N stage (N0-1 vs. N2) had significantly shorter OS (p<0.05), PFS (p<0.05), and LR-PFS (p<0.05) outcomes, respectively, which were also confirmed using a multivariate analysis (p<0.05). Conclusion: Our results demonstrated that the established prognostic factors, including T and N stages, were important prognostic indicators of NPC in elderly patients

    Outcomes of aggressive treatment in esophageal cancer patients with synchronous solitary brain metastasis
    (2017) Onal, Cem; Yildirim, Berna Akkus; Guler, Ozan Cem; 0000-0002-2742-9021; 0000-0001-6661-4185; 0000-0001-6908-3412; 28685086; D-5195-2014; V-5717-2017; AAC-5654-2020
    The aim of the present study was to investigate the outcomes of esophageal cancer (EC) patients with isolated synchronous brain oligometastasis (oligo-BM) treated with chemoradiotherapy (CRT) of the primary site and localized treatment of the BM with surgery, radiotherapy (RT) or radiosurgery. Of 125 EC patients investigated, seven patients (6%) had solitary BM. Six patients were diagnosed prior to, and one patient was diagnosed during, treatment. All patients were treated with neoadjuvant chemotherapy and whole-brain RT (WBRT) for BM. All but one patient received definitive CRT with a median RT dose of 50.4 Gy using conventional fractionation RT. The median age at diagnosis was 59 years (range, 48-77 years). Six patients succumbed to mortality, and one continued to receive systemic chemotherapy at the last visit. The median survival time of the patients was 18.9 months (range, 10.0-27.2 months). Median time to progression after completion of the treatments was 8 months (range, 3-9 months). Two patients had progression of the primary tumor, and one patient had progression of the BM. The neurological status of three patients with BM who were identified during the staging work-up did not deteriorate as a consequence of WBRT. In conclusion, the present study has demonstrated that aggressive treatment of the primary tumor and oligo-BM in patients with EC may prolong the survival time.
