Introduction:We aimed to assess the effect of anti-tyrosine kinase inhibitors (TKIs) (gefitinib) in overall survival (OS) of the glioblastoma multiforme (GBM) patients in the backdrop of mutational status of epidermal growth factor receptor (EGFR) and PTEN genes.Materials and Methods:All the patients subjected to resection or biopsies were put on gefitinib, and radiotherapy was delivered as per the hospital protocol. EGFR and PTEN mutational spectrum was performed by single-strand conformation polymorphism followed by DNA sequencing.Results:In total, 50% GBM tumors had mutation either in EGFR or PTEN. Median progression-free survival (PFS) and OS observed in patients with EGFR +ve/PTEN −ve were significantly favorable (P < 0.05) which aggregated to 9(7, 11) months and 20 (16, 24) months, respectively, than 6 (4, 8) months and 13 (7, 19) months in patients with PTEN +ve/EGFR −ve. Patients positive for both EGFR/PTEN had lower disease-free survival and OS of 6 and 9 months as compared to 6 (5, 7) and 14 (12, 24) months for those negative for both EGFR/PTEN.Conclusions:We conclude that EGFR gene alterations with wild-type PTEN are associated with significantly better PFS and OS in patients treated with anti-TKIs (gefitinib). Combined EGFR and PTEN gene mutation is associated with significantly poor response to gefitinib in terms of median OS.
Objectives:To compare the effectiveness and tolerability of misoprostol as a cervical ripening agent in first trimester abortion through three different routes of administration before surgical evacuation (SE).Materials and Methods:It was a hospital based prospective randomized open labeled parallel study. A total of 150 randomly selected married women were divided in three groups for sublingual (S/L), vaginal and oral 400 μg of misoprostol single dose administration. The drug was administered 3-4 h before SE in the S/L and vaginal groups and 12 h before the procedure in the oral group. Efficacy was assessed on the basis of time taken for ripening, dilatation achieved, duration of the procedure, intra-operative blood loss, and pain score. The tolerability was noted on the basis of side effects.Results:The mean time taken for cervical ripening was less in sublingual administration (3.7±1.2 hr) as compared to the vaginal and oral routes. The S/L group had significant cervical dilatation (P<0.001) and the duration of SE was less as compared to the vaginal and oral routes. However, the mean intraoperative blood loss was more in sublingual as compared to the vaginal and oral groups. The intra-operative pain score of the S/L group was significantly lower (1.9±1.1, P<0.05) as compared to the vaginal (2.6±1.7) or oral route (3.3±1.7). Loose motions and nausea/vomiting were more with the S/L and oral routes while blood loss was more in the vaginal route.Conclusion:Administration of misoprostol by the sublingual route is better than the oral and vaginal routes for cervical ripening.
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.
