AIM: In this study, factors affecting survival, local failure, distant brain failure, whole brain failure and whole-brain radiation therapy (WBRT) free survival according to histological subtypes were investigated in patients with brain metastases from non-small cell lung cancer (NSCLC). MATERIAL and METHODS: Patients with positive pathology reports for adenocarcinoma (ACA) and squamous cell carcinoma (SCC) were included in the study. Seventy-eight ACA and 26 SCC patients were included in the study. Patients with previous history of cerebral metastasis surgery and WBRT were excluded from the study. RESULTS: The median survival was calculated as 12.6 months for patients with ACA and 5.9 months for patients with SCC. One-year distant brain failure was calculated as 65.1% in ACA patients and 39.6% in SCC patients. One-year whole brain failure was calculated as 58.1% in ACA patients and 39.6% in SCC patients. The one-year freedom from WBRT rate was calculated as 72.8% in ACA patients and 56.3% in SCC patients. SCC histology was considered as a significant factor in deterioration of overall survival in multivariate analysis. SCC histology, the increase in the number of metastases and RPA class were factors that caused an increase in distant brain failure. Also, SCC histology, the increase in the number of metastases and RPA class were factors that caused an increase in whole brain failure. CONCLUSION: SCC histology may be an important prognostic factor for overall survival. Also, due to high distant brain failure rate in SCC histology, WBRT can be added to treatment early.
Rapid Spontaneous Resolution of Acute Epidural Hematoma: A Case Report and Review of the Literature
(2016) Aydemir, Fatih; Cekinmez, Melih; Kardes, Ozgur; Sarica, Feyzi Birol; 27308088
Background: Epidural hematomas (EDH) are pathologies in which the early diagnosis and treatment are important. Resolution under 24 hours is very rare. Case Report: An 11-month-old male patient was brought to the emergency department with head trauma from falling out of bed onto his back. There were no neurological deficits, except for the patient being somnolent. Computed tomography (CT) of the patient revealed subgaleal edema in the right parietal region, linear fracture and image consistent with EDH with a thickness of about 9 mm underneath fracture. A control CT was performed after 3 hours as somnolence continued in follow-up of the patient. Hematoma in the epidural region was observed to completely resolve and edema in the subgaleal region was observed to gain hemorrhagic characteristics. Conclusion: In total, 15 cases have been reported, including our case, in the literature with resolution less than 24 hours. Our case has the fourth fastest resolution ever reported in the English literature. We think that the most important factor in the rapid spontaneous resolution is the presence of a connection between the epidural and epicranial space, either through a fracture or cranial sutures
