Long‐term outcomes in sinonasal squamous cell carcinoma arising from inverted papilloma: Systematic review

xlomafota13 shared this article with you from Inoreader Long‐term outcomes in sinonasal squamous cell carcinoma arising from inverted papilloma: Systematic review Via Head & Neck Abstract Long-term survival and recurrence patterns of squamous cell carcinoma arising from inverted papilloma (IP-SCC) have not been thoroughly investigated. Four electronic databases were searched and primary studies describing overall survival (OS), recurrence, and mean time to recurrence of patients with IP-SCC were included for review. Our search yielded 662 studies. The 28 studies selected for inclusion identified 663 patients with IP-SCC. In 596 patients with reported T classification, 439 (73.7%) were T3/T4 on presentation. Of the 650 participants with recurrence data (local, regional, and distant), 155 (23.8%) experienced a recurrence, with an aggregate mean time-to-recurrence of 24.3 months. In 565 patients with 5-year OS rates, the aggregate 5-year OS was 62%. Based on the literature to date, IP-SCC is associated with a 5-year OS rate of 62%. 23.8% of patients experienced recurrence at a mean time of 24.3 months, suggesting the need for long-term surveillance.

Selected by bioinformatics and molecular docking analysis, Dhea and 2–14,15-Eg are effective against cholangiocarcinoma

xlomafota13 shared this article with you from Inoreader Selected by bioinformatics and molecular docking analysis, Dhea and 2–14,15-Eg are effective against cholangiocarcinoma Via Head and neck cancers by Lei Qin, Jun Kuai, Fang Yang, Lu Yang, Peisheng Sun, Lanfang Zhang, Guangpeng Li Object To identify novel targets for the diagnosis, treatment and prognosis of cholangiocarcinoma, we screen ideal lead compounds and preclinical drug candidates with MYC inhibitory effect from the ZINC database, and verify the therapeutic effect of Dhea and 2–14,15-Eg on cholangiocarcinoma. Methods The gene expression profiles of GSE132305, GSE89749, and GSE45001 were obtained respectively from the Gene Expression Omnibus database. The DEGs were identified by comparing the gene expression profiles of cholangiocarcinoma and normal tissues. GO, KEGG analysis and PPI network analyses were performed. LibDock, ADME and toxicity prediction, molecular docking and molecular dynamics simulations were used to identify potential inhibitors of MYC. Moreover, in vitro, MTT assay, colony-forming assay, the scratch assay and Western blotting were performed to verify the therapeutic effect of Dhea and 2–14,15-Eg. Results PPI network analysis showed that ALB, MYC, APOB, IGF1 and KNG1 were hub genes, of which MYC was mainly studied in this study. A battery of computer-aided virtual techniques showed that Dhea and 2–14,15-Eg have lower rodent carcinogenicity, Ames mutagenicity, developmental toxicity potential, and high tolerance to cytochrome P4502D6, as well as could exist stably in natural circumstances. In vitro assays showed that Dhea and 2–14,15-Eg inhibited cholangiocarcinoma cellular viability, proliferation, and migration inhibiting expression of MYC. Conclusion This study suggested that Dhea and 2–14,15-Eg were novel potential inhibitors of MYC targeting, as well as are a promising drug in dealing with cholangiocarcinoma and have a perspective application.

Two‐Incision Approach for Hypoglossal Nerve Stimulator Placement: A Single Institution Assessment

xlomafota13 shared this article with you from Inoreader Two‐Incision Approach for Hypoglossal Nerve Stimulator Placement: A Single Institution Assessment Via The Laryngoscope Objective(s) Upper airway stimulator (UAS) placement is a treatment for obstructive sleep apnea (OSA) with few complications and low morbidity. UAS placement has traditionally been performed using a three-incision approach, however, it has been implanted using a two-incision approach. This approach could significantly decrease operation time without a difference in postoperative complications, demonstrating its safety and feasibility for UAS placement. The objective was to assess operative time and complication rate in the two-incision approach for UAS placement compared to the three-incision approach. Study Design Retrospectively reviewed. Methods Patients who underwent UAS placement using the two- or three-incision approach at a single academic institution from November 2014 to June 2021 were retrospectively reviewed. The two-incision approach did not include the incision at the mid-axillary line. Main outcome measures included operation time and complication rates. Results Three-hundred forty-eight patients underwent UAS placement. The three-incision approach demonstrated an average operation time of 143.3 minutes whereas the two-incision approach averaged 129.4 minutes (P < .001). There was no significant difference in rate of postoperative complications between the two- and three-incision cohorts including pneumothorax (0% vs. 0.4%, P > .99), patient-reported discomfort (5.6% vs. 6.5%, P > .99), activity restriction (0% vs. 1.4%, P > .50), and incisional pain (0.0% vs. 1.0%, P > .99). No patients experienced incision site bleeding or infection. The two-incision approach was associated with decreased rate of revision surgery (0.0% vs. 5.4%, P = .048). Conclusion The UAS two-incision approach proved to have a significantly shorter operative time without an increase in complications as compared to the three-incision approach. This approach is a safe and feasible option. Level of Evidence III Laryngoscope, 2022 View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Management of postradiation late hemorrhage following treatment for HPV‐positive oropharyngeal squamous cell carcinoma

xlomafota13 shared this article with you from Inoreader Management of postradiation late hemorrhage following treatment for HPV‐positive oropharyngeal squamous cell carcinoma Via Head & Neck Abstract Background Acute oropharyngeal hemorrhage is a serious complication for patients with oropharyngeal squamous cell carcinoma (OPSCC), particularly in patients with a history of radiation therapy (RT). Methods Retrospective case series from at a tertiary care center for treated patients with HPV-positive OPSCC presenting with oropharyngeal hemorrhage. Results Median time from completion of chemoradiation to first hemorrhagic event was 186 days (range 66–1466 days). Seven patients (58%) required intervention to secure their airway. All patients were evaluated for endovascular intervention, six (50%) were embolized. Eight patients (67%) had a second hemorrhagic event; median time to second bleed was 22 days (range 3–90 days). Conclusions Acute oropharyngeal hemorrhage is a sequelae following treatment for HPV-positive OPSCC. The majority of bleeds occurred within a year of completion of treatment. While more research is needed to determine optimal treatment paradigms, endovascular intervention should be considered, even if noninvasive imaging does not demonstrate active bleeding.
