    Access to Radiation Therapy by Syrian Refugees Displaced to Turkey
    (ELSEVIER INC, 2022-01-01) Dagoglu, Nergiz; Karaman, Sule; Atalar, Banu; Miller, Robert C.; Oral, Ethem N.
    For over 10 years, the Syrian conflict has caused millions of people to leave their homeland, causing one of the biggest refugee crises in modern history. Considering its prevalence, cancer is an important care burden among Syrian refugees. Radiation therapy is one of the essential parts of cancer treatment, and radiation oncology departments must guarantee optimal cancer treatments even in such a challenging setting when patients are displaced forcefully from their homes. National and institutional measures are highlighted in this manuscript to provide suggestions for the delivery of care during refugee crises. There are two issues creating barriers to serving refugee populations: the loss of access to their original care records in Syria for those with a previous diagnosis of cancer referred for continuation of radiation therapy or reirradiation, and the effect of acute radiation therapy toxicity on treatment compliance.

    National Multi-Center Observational Retrospective Study to Understand Treatment Patterns and Outcomes for Stage III Non-Small Cell Lung Cancer Patients in Turkey: Turkish Society for Radiation Oncology Study, STONE Trial

    This study investigated treatment patterns and outcomes in patients with inoperable stage III non-small cell lung cancer (NSCLC) treated with radiotherapy (RT) in Turkey. We included 492 patients with stage III NSCLC in this multi-center retrospective study. Pa-tient demographics, clinical characteristics, and clinical treatment patterns from the time of the initial diagnosis to disease progression were recorded. Additionally, the prognostic factors predicting overall survival (OS) and progression-free survival (PFS) were analyzed. For the initial treatment, 429 patients (89.2\%) received chemotherapy and RT, whereas 53 patients (10.8\%) were treated only with RT. The first disease progression occurred in 288 patients (58.4\%) at 9.3 months (median) after the initial treatment, and 64.6\% re-ceived treatment after first progression. The second disease progression occurred in 30 patients, and 20 patients (66.7\%) received treatment. Median OS and PFS were 27.0 months and 13.4 months, respectively. Age (p< 0.001), stage (p= 0.04), poor performance score (PS) (p= 0.03) and RT doses (p= 0.002) were independent predictors for OS and PFS in our multivariate analysis. Additional significant predictors for OS in the multivariate analysis were gender (p= 0.004), treatment period (0.02), and irradiation technique (p= 0.02). Disease progression occurred in nearly 58\% of the patients, and one-third of these patients remained untreated during the disease progression. These findings indicate a need for additional treatment options in patients with unresectable stage III NSCLC with high-risk features, namely older age, stage IIIB disease, poor PS, and lower RT doses.
