Reconstruction following transoral robotic surgery for head and neck cancer: Systematic review

xlomafota13 shared this article with you from Inoreader Reconstruction following transoral robotic surgery for head and neck cancer: Systematic review Via Head & Neck Abstract We performed a systematic review to characterize reconstructive modalities and postoperative surgical outcomes following TORS resection. A search of the PubMed, SCOPUS, and EMBASE databases was conducted to identify studies describing patients undergoing reconstruction of TORS defects. Twenty-six studies met inclusion criteria, consisting of 260 patients who underwent TORS resection followed by reconstruction. Twenty-one studies reported tumor classification information, with TORS performed for 44 (23.0%) T1, 86 (45.0%) T2, 33 (17.3%) T3, and 28 (14.7%) T4 tumors. Eighteen distinct reconstructive modalities were described in the studies identified, including nine unique free flap types. The most commonly performed reconstruction was the radial forearm free flap (RFFF), accounting for 121/260 (46.5%) of reconstructions performed. Reported surgical complications included 5 pharyngocutaneous fistulae, 13 hemorrhagic complications, 24 infectious complications, and 5 free flap failures . Our findings demonstrate favorable surgical outcomes but minimal quantitative functional data to compare reconstructive options following TORS. View on the web Inoreader.

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.

The effect of cosmetic surgery on mental self-image and life satisfaction in women undergoing breast augmentation: An intermediate role of evaluating the surgery as one of the most important life events

xlomafota13 shared this article with you from Inoreader The effect of cosmetic surgery on mental self-image and life satisfaction in women undergoing breast augmentation: An intermediate role of evaluating the surgery as one of the most important life events Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2022 Jan 21:S1748-6815(22)00033-X. doi: 10.1016/j.bjps.2022.01.018. Online ahead of print. ABSTRACT AIM: To estimate changes in self-perception and satisfaction in women undegoing breast augmentation surgery (BAS). METHODS: Using a quasi-experimental questionnaire study design, we enrolled a cohort of BAS women treated at a private clinic during a 5-year interval. The primary predictor variable was treatment (before/after). The main outcome variables included effect of considering breast augmentation as one of the most important life events on self-image (BAOMILE), and subjective evaluation of physical appearance and life satisfaction. Other study variables were demographic data. The Mann-Whitney and the Wilcoxon signed-rank tests were used to compare the outcomes between before and after the surgery. The Spearman rank correlation and the Pearson chi-squared test were computed to analyze the relatio nships among variables. RESULTS: The sample consisted of 53 subjects (52.3% married; 40.9% from medium-sized towns) with a mean age of 33.2 ± 6.4 years (range, 21-46). Life satisfaction was significantly increased after BAS in the whole cohort (preop., 7.83 vs. postop., 8.42; P = .003; 95% CI, -0.95 to -0.22) as well as in the BAOMILE subgroup (preop., 7.87 vs. postop., 8.56; P = .011; 95% CI, -1.20 to -0.17). Within the BAOMILE subgroup, there was a positive correlation between the appearance assessment and the number of positive traits before surgery (ρ = 0.63; P = .002; 95% CI, 0.27-0.83) and life satisfaction after surgery (ρ = 0.480; P = .03; 95% CI, 0.06-0.74). CONCLUSIONS: The results of this study suggest that BAS improves self-perception and life satisfaction of the patients. The psychologist's role in understating patient's motivation for cosmetic surgery and the revision of their attitudes towards expected effects require further investigations.

Mitochondrial DHODH regulates hypoxia-inducible factor 1 expression in OTSCC

xlomafota13 shared this article with you from Inoreader Mitochondrial DHODH regulates hypoxia-inducible factor 1 expression in OTSCC Via American Journal of Cancer Research Am J Cancer Res. 2022 Jan 15;12(1):48-67. eCollection 2022. ABSTRACT Oral tongue squamous cell carcinoma (OTSCC) was one of the most hypoxic tumors with unfavorable outcomes. Hypoxia-inducible factor-1 (HIF-1) signaling was associated with cancer proliferation, lymph node metastasis, angiogenesis and poor prognosis of OTSCC. Dihydroorotate dehydrogenase (DHODH) catalyzed the rate-limiting step in the de novo pyrimidine biosynthesis. The aim of the study was to explore the biological function of DHODH and investigate whether DHODH regulated HIF-1 signaling in OTSCC. Proliferation, migration and anoikis resistance were used to determine the function of DHODH. Western blot and luciferase activity assays were used to determine the regulatory role of DHODH on HIF-1. We found that increased DHODH expression was associated with advanced tumor stage and poorly differentiated tumor in head and neck cancer patients in The Cancer Genome Atlas (TC GA). DHODH enhanced the proliferation and aggressiveness of OTSCC. Moreover, DHODH prompted tumor growth and metastasis in vivo. DHODH promoted transcription, protein stability, and transactivation activity of HIF1A. DHODH-induced HIF1A upregulation in OTSCC can be reversed by reactive oxygen species (ROS) scavenger, indicating that DHODH enhanced HIF1A expression via ROS production. DHODH inhibitor suppressed DHODH-mediated ROS generation and HIF1A upregulation. Targeting DHODH using clinically available inhibitor, atovaquone, might provide a new strategy to treat OTSCC.

Definitive radiation therapy and liver local therapy in de novo liver metastatic nasopharyngeal carcinoma: Large cohort study

xlomafota13 shared this article with you from Inoreader Definitive radiation therapy and liver local therapy in de novo liver metastatic nasopharyngeal carcinoma: Large cohort study Via Head & Neck Abstract Background We aimed to evaluate patients suitable for definitive radiation therapy (DRT) and liver local therapy (LLT) in addition to palliative chemotherapy (PCT) among those with de novo liver metastatic nasopharyngeal carcinoma (lmNPC). Methods The overall survival (OS) and progression-free survival (PFS) rates were calculated and compared in 610 patients with lmNPC. Results Both the PCT+DRT and PCT+DRT+LLT groups had better survival outcomes than the PCT group. Among patients with complete response/partial response (CR/PR) after PCT, no significant differences in survival rates were observed between those treated with PCT+DRT and PCT+DRT+LLT (2-year PFS: 27.0% vs. 32.9%, p = 0.263). Among patients with progressive disease/stable disease (PD/SD) after PCT, significantly better survival rates were observed in patients treated with PCT+DRT+LLT. Conclusions DRT might benefit patients with lmNPC regardless of the tumor response after PCT. For patients with CR/PR, LLT might not be needed. For patients with PD/SD, LLT might improve survival outcomes. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

ST3GAL2 knock-down decreases tumoral character of colorectal cancer cells in vitro and in vivo

xlomafota13 shared this article with you from Inoreader ST3GAL2 knock-down decreases tumoral character of colorectal cancer cells in vitro and in vivo Via American Journal of Cancer Research Am J Cancer Res. 2022 Jan 15;12(1):280-302. eCollection 2022. ABSTRACT Tumor cells have a modified glycosylation profile that promotes their evolution and/or their maintenance in the tumor. Sialylation is a type of glycosylation that is often altered in cancers. RNA-Seq database analysis revealed that the sialyltransferase gene ST3GAL2 is significantly overexpressed at all stages of colorectal cancer (CRC). ST3GAL2 sialylates both glycoproteins and glycolipids. The aim of this work was to investigate the involvement of ST3GAL2 in CRC. Using the HT29 tumor cell line derived from a stage II of CRC, we decreased the expression of ST3GAL2 by specific shRNA, and then characterized these cells by performing functional tests. We found that ST3GAL2 knock down (KD) significantly decreases tumor cell proliferation, cell migration and invasiveness properties in vitro. The cell cycle of these cells is affected with a ch ange in cell cycle distribution and an increase of cell apoptosis. The effect of ST3GAL2 KD was then studied in vivo, following xenografts into nude mice, in which the tumor progression was significantly reduced. This work demonstrates that ST3GAL2 is a major player in the behavior of colorectal tumor cells, by modifying the sialylation state of glycoproteins and glycolipids which remain to be specifically identified.
