Background
Access to cancer care is a problem that continues to plague refugees displaced from their home countries. The turbulent political crisis in Syria, which has led to millions of refugees seeking asylum in Turkey, merits further attention. We aimed to study the rate of utilization of radiation therapy among Syrian refugees with cancer living in Turkey in an attempt to identify the contributing factors predictive of non-compliance with prescribed RT.
Methods
In this retrospective review of 14 institutional databases, Syrian refugee patients in Turkey with a cancer diagnosis from January 2015 to December 2019 who were treated with RT were identified. The demographic data, treatment compliance rates, and toxicity outcomes in these patients were surveyed. Variable predictors of noncompliance such as age, sex, diagnosis, treatment length, and toxicity were studied. The association between these variables and patient noncompliance was determined.
Results
We identified 10,537 patients who were diagnosed with cancer during the study period, of whom 1010 (9.6%) patients were treated with RT. Breast cancer (30%) and lung cancer (14%) were the most common diagnoses with up to 68% of patients diagnosed at an advanced stage (Stage III, IV). 20% of the patients were deemed noncompliant. Treatment with concurrent chemoradiotherapy (OR 1.61, 95% CI 1.06–2.46, p = 0.023) and living in a refugee camp (OR 3.62, 95% CI 2.43–5.19, p < 0.001) were associated with noncompliance. Age, sex and treatment length were not significantly associated with noncompliance.
Conclusions
Noncompliance with radiotherapy among Syrian refugees in Turkey remains an area of concern with a multitude of factors contributing to these alarming numbers. Further studies to better ascertain the finer nuances of this intricately complex problem and a global combination of efforts can pave the way to providing a solution.
Malignant pleural mesothelioma (MPM) is a rare disease with a poor prognosis. The main therapeutic options for MPM include surgery, chemotherapy, and radiation therapy (RT). Although multimodality therapy has been reported to improve survival, not every medically operable patient is able to undergo all recommended therapy. With improvements in surgical techniques and systemic therapies, as well as advancements in RT, there has been a potential new paradigm in the management of this disease. In this review, we discuss the current literature on MPM management and propose a functional treatment algorithm.
Ependymomas commonly arise in the central nervous system. Extraneural presentation is quite rare. Herein, we describe a primary extraneural ependymoma in a young female. The mass was located in the right inguinal area. The cut surface of the 7.5 mm × 6.5 mm × 4.5 mm sized tumor was brownish-yellow in color. Histologically, it was hypercellular exhibiting pseudorosette or rosette formations and some papillary structures. Mitosis was counted as high as 10 per 10 high power fields. Neither necrosis nor vascular endothelial proliferation within the tumor was observed. Tumor cells showed strong glial fibrillary acidic protein immunoreactivity. On epithelial membrane antigen, intracytoplasmic dot-like immunostaining was observed. This is the first report presenting a primary extraneural anaplastic ependymoma arising in the inguinal subcutaneous region.
Background: Lung cancer is the leading cause of cancer death, late diagnosis being the main obstacle to improving the outcomes with stage at diagnosis as an important prognostic factor. Relationships between ABO blood groups and risk of benign or malignant diseases have been observed and in this study, we aimed to investigate whether they might affect prognosis and response to chemoradiotherapy in patients with local advanced non-small cell lung cancer (NSCLC). Materials and Methods: Eighty-one patients with non-metastatic local advanced NSCLC were included in the study. ABO blood groups were A in 45 (55.6%), B in 7 (8.6%), AB in 8 (9.9%), and O in 21 (25.9%) patients. The patients were also divided two groups according to blood group A (45 patients) and non-A (B, AB and O; 36 patients). Response to chemoradiotherapy was complete remission in 10 (12.3%), disease regression in 42 (51.9%), stable disease in 12 (14.8%), and disease progression in 17 (21.0%) patients. Results: There was no significant difference among ABO blood group categories or between patients with A blood group and those with non-A blood group in terms of responses to chemoradiotherapy (p>0.05). There were also no significant differences regarding overall and disease-free survival rates. Conclusion: The ABO blood group system has no significant effect on prognosis and response to chemoradiotherapy in patients with non-metastatic NSCLC.
PurposeInvolvement of human kallikreins (hKs) in human cancers has been reported and several hKs are promising biomarkers of various cancers. The aim of this study was to evaluate the prognostic significance of hK11 expression in patients with non-metastatic non-small cell lung cancer (NSCLC).Materials and MethodsThe study included 44 patients with NSCLC. hK11 expression was determined by immunohistochemical staining.ResultsThe estimation of disease-free and overall survival by Kaplan-Meier was 11 months and 17 months, respectively. The estimation of overall survival by Kaplan-Meier was significantly higher in patients with hK11 strongly positive (2+) than in those with hK11 weakly positive (1+) (20 months vs. 11 months, p=0.032). Although not statistically different, the estimation of disease-free survival by Kaplan-Meier was higher in patients with hK11 strongly positive (2+) than in those with hK11 weakly positive (1+) (12 months vs. 9 months, p=0.113). Multivariate Cox regression analysis showed that the overall survival rates were significantly associated with response to chemoradiotherapy and the degree of staining with hK11.ConclusionThe stronger hK11 expression in NSCLC appears to be associated with better survival rates. hK11 may be a prognostic biomarker of NSCLC.
