Background:Lipids play an important role in maintaining the cell membrane integrity. Lipid profile is a panel of blood tests that serve as an initial medical screening for abnormalities in lipids and approximate risk for cancer, cardiovascular diseases, pancreatitis, etc., The present study evaluates the alterations in lipid profile in cancer patients, smokers, and nonsmokers and aims to achieve a correlation between them.Materials and Methods:The study is an in vitro type of cross-sectional study with 25 oral cancer patients, 25 chronic smokers (habit persisting for 15 years or more), and 15 nonsmokers as control group. Blood samples had been collected, and triglycerides (TGs), total cholesterol (TC), high-density lipoprotein (HDL), very low-density lipoprotein (VLDL), and low-density lipoprotein (LDL) were analyzed using a lipid profile kit and an autoanalyzer. The results were analyzed using the unpaired t-test and ANOVA test (P < 0.05).Results:There was a significant increase in TC, TG, LDL, and VLDL and decrease in HDL in the smokers group when compared to the controls (P < 0.05). A significant increase in LDL, but a decrease in values of HDL, VLDL, TG, and TC was observed in the cancer patients group when compared to the controls (P < 0.05).Conclusion:There is an inverse relationship between serum lipid profile in smokers and cancer patients. The decrease in lipid profile in cancer patients might be due to their increased utilization of lipids by neoplastic cells in membrane biogenesis. Therefore, a decrease in lipid profile in smokers can be assumed that they might be more prone to develop cancerous conditions.
Ewing's sarcoma is rare sarcoma of bone and soft tissue that uncommonly involve the head and neck in both bone and soft tissue locations. The term Ewing's sarcoma family of tumors comprises both Ewing's sarcoma and peripheral neuroectodermal tumor. It was in 1975, Angervall and Enzinger described the Ewing's sarcoma arising in soft tissues (extraskeletal). The principal sites of extraskeletal Ewing's sarcoma are the paravertebral region and chest wall, generally in close association with vertebrae or the ribs. These tumors may also arise in the soft tissues of the lower extremities and rarely in the pelvic region and hip regions. Superficially located cases do occur but are rare. Here, we present a case of Ewing's sarcoma involving the maxillary sinus region. A 12-year-old boy reported to our department with a swelling on the right side of middle third of the face for 15 days. Intraorally, there was only obliteration of the labial vestibule. On histopathological examination, a provisional diagnosis of malignant round cell tumor was given. Immunohistochemistry with a panel of markers was done to come to a definitive diagnosis. CD99 positivity confirmed the diagnosis of Ewing's sarcoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
