Stroke is the third leading cause of mortality worldwide. Combined carotid intima-media thickness (CIMT) is a marker of atherosclerosis and is also a predictor for ischemic stroke. We determined the frequency of CIMT in patients with acute ischemic stroke and in matched controls and also the risk factors for CIMT. Sixty patients with ischemic stroke diagnosed by computer tomography (CT) scan and 50 controls matched by age, gender, diabetes, and hypertension were studied. Subjects in both groups underwent carotid duplex scanning (ACUSON 128 x P/10 machine) with a 7.5 MHz linear superficial array probe in B-mode to determine the CIMT and presence of plaques. The mean age in the patient group was 62 years and 63.3% were males. The average CIMT in the patient group was 0.798 mm and it was 0.6 mm in the control group (P < 0.0001). Patients with carotid plaque had significantly increased IMT (0.95 +/- 0.22) when compared to patients without plaques (0.71 +/- 0.12) (P < 0.001). When the differences in mean IMT were compared among the different age groups in the patient group, there was significance (P < 0.05). In this study the CIMT was independently associated with increasing age and with the presence of carotid plaques.
Background. Locally advanced carcinoma of maxillary sinus has been historically reported to have poor prognosis. We evaluated the role of NACT in improving the outcome in these patients. Methods. 41 patients with locally advanced technically unresectable (stage IVa) or unresectable maxillary carcinoma (stage IVb) were treated with induction chemotherapy between 2008 and 2011. The demographic profile, response and toxicity of chemotherapy, definitive treatment received, progression free survival (PFS), and overall survival (OS) were analyzed. Univariate and multivariate analysis were performed to determine factors associated with PFS and OS. Results. The chemotherapy included two drugs (platinum and taxane) in 34 patients (82.9%) and three drugs (platinum, taxane, and 5 FU) in 7 (17.1%). There was no complete response seen in any of the patients, stable disease in 18 (43.9%), partial response in 16 (39%), and progression in 7 (17.1%) patients. After induction, the treatment planned included surgery in 12 (29.3%), CT-RT in 24 (58.5%), radical RT in 1 (2.4%), palliative RT in 1 (2.4%), and palliative chemotherapy in 3 (7.3%) patients. Overall, the median PFS was 10.0 months. The OS at 24 months and 36 months was 41% and 35%, respectively. Conclusion. In unresectable maxillary carcinoma, induction chemotherapy has clinically significant benefit with acceptable toxicity.
Cytotoxic antiproliferative chemotherapeutic agents are the mainstay of treatment in cancers. Chemotherapy is usually administered every 2-3 weeks. Along with acute toxicity and long-term effects of cumulative doses, this strategy potentially allows regrowth of the tumor in the interval period and leads to the emergence of resistant populations of tumor cells. Moreover, even with intense chemotherapy, the outcome is stagnating for most of the tumors. There has been recent interest in the use of chemotherapy in fractionated doses which is far below the maximum tolerated dose. This is called metronomic scheduling of chemotherapy. Here, we review the biology and evidence for metronomic chemotherapy.
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.
