Project description:Adjuvant chemoradiation is reported to have a survival benefit for esophageal squamous cell carcinoma (ESCC). We evaluated the "upfront surgery and pathological stage-based adjuvant chemoradiation" strategy, in which adjuvant therapy is guided by pathological stage, in locally advanced ESCC. Data from 2976 clinical stage II/III ESCC patients, including 1735 in neoadjuvant chemoradiation and 1241 in upfront surgery groups, were obtained from a nationwide database. Patients in the upfront surgery group were further categorized into the "upfront surgery and pathological stage-based adjuvant chemoradiation" and "upfront surgery only" groups. The 3-year overall survival (OS) rates in the "neoadjuvant chemoradiation", "upfront surgery and pathological stage-based adjuvant chemoradiation", and "upfront surgery only" groups were 41.5%, 45.8%, and 28.5%, respectively. In propensity score matched patients, the 3-year OS rate was 41.7% in the neoadjuvant chemoradiation group, compared to 35.6% in the "upfront surgery and pathological stage-based adjuvant chemoradiation" group (p?=?0.147), and 20.3% in the "upfront surgery only" group (p?<?0.001). No survival difference was observed between the "neoadjuvant chemoradiation followed by surgery" protocol and the "upfront surgery and pathological stage-based adjuvant chemoradiation" strategy.

Project description:BackgroundThere is a paucity of studies reporting long-term survival outcomes for HPV/p16 positive oropharyngeal squamous cell carcinoma (OPSCC). This study aims to compare long-term outcomes of advanced stage p16 positive and negative OPSCCs, treated by surgical and non-surgical modalities.MethodsOPSCC patients from 1998 to 2012 were identified through a prospectively collected cancer registry. P16 immunohistochemistry was used as a surrogate marker for HPV-OPSCC. Overall survival (OS) and aspiration free survival (AFS) comparisons were made between patients treated with chemoradiation (CRT) versus primary surgery and radiation/chemoradiation (S+RT/CRT) at 5, 10 and 15 years post-treatment.ResultsA total of 319 patients were included. P16 positive patients and non-smokers had significantly higher long-term (5, 10 and 15-year) OS. Smokers and p16 negative patients treated with S+RT/CRT had improved long-term OS compared to patients who received CRT. Smokers and p16 negative patients had lower long-term AFS. Multivariate analysis showed improved OS was associated with p16 positivity (HR 0.42, 0.28-0.61) and surgery (HR 0.47, 0.32-0.69), whereas lower OS was associated with ECOG ≥ 2 (HR 2.46, 1.61-3.77), smoking (HR 2.37, 1.41-3.99) and higher stage (HR 1.68, 1.05-2.68).ConclusionsIn smokers and p16-negative OPSCC patients, primary surgery may be associated with improved long-term survival and dysphagia-related outcomes.

Project description:Aims:Advanced stage of oral squamous cell carcinoma (OSCC) exhibits different properties compared with the early stage for example an invasion ability. The present study investigated a differential gene expression of surgical margin between advanced and early stage of OSCC. Methods:Gene Expression Omnibus dataset (GSE31056) was downloaded and re-analyzed. Surgical margin samples were categorized into 2 groups; early stage and late stage. Differential gene expression analysis was performed. Dysregulated genes were further analyzed for gene ontology, enriched pathway, and disease association using a network-based analysis tools. Results:Eighty-five dysregulated genes were identified in margin of late stage OSCC. Metabolic process and biological regulation were the main gene ontology of dysregulated genes. Genes involved in Jak-STAT signaling pathway were upregulated in late stage of surgical margin samples. In addition, seven upregulated genes in late stage group, namely CEBPB, S1PR1, IL6, CEBPD, CHI3L1, PTX3, and SOCS3, were categorized in acute phase reaction and inflammation categories of disease association analysis. Conclusion:The differential expressed genes in surgical margin of late stage OSCC could be further employed to understand cancer's behavior and to identify target pathway to prevent OSCC invasion.

Project description:Aspirin-exacerbated respiratory disease (AERD) is diagnosed through graded aspirin challenges that induce hypersensitivity reactions and eicosanoid level changes. It is not known whether diagnostically useful changes also occur after low-dose aspirin challenges that do not induce hypersensitivity reactions.To investigate the utility of low-dose oral aspirin challenges for diagnosing AERD by measuring different clinical parameters and eicosanoid changes.Sixteen patients with AERD and 13 patients with aspirin-tolerant asthma underwent oral challenges with low-dose (20 or 40 mg) aspirin and diagnostic oral graded aspirin challenges (up to 325 mg of aspirin). Forced expiratory volume in 1 second, nasal peak flow, the fraction of exhaled nitric oxide (FeNO), and eicosanoid levels in plasma and urine were analyzed.In patients with AERD but not in those with aspirin-tolerant asthma, 40-mg aspirin challenges induced a significant mean (SEM) decrease from baseline in FeNO (19% [5.1%]; P = .001) without causing any hypersensitivity reaction. The FeNO decrease also occurred after higher-dose aspirin challenges (27.8% [4.9%]; P < .001). The sensitivity and specificity of 40-mg aspirin-induced FeNO changes for identifying AERD were 90% and 100% with an area under the curve of 0.98 (95% CI, 0.92-1.00). The low-dose challenge also induced a significant leukotriene E4 urine increase in patients with AERD (from 6.32 [0.08] to 6.91 [0.15] log-pg/mg creatinine; P < .001), but the sensitivity and specificity of these changes were less than for the FeNO changes.The low-dose aspirin-induced decrease in FeNO in patients with AERD may be useful for the diagnosis of aspirin allergy without inducing a hypersensitivity reaction.clinicaltrials.gov Identifier: NCT01320072.

Project description:This study focused on the expression of mitochondrial serine hydroxymethyltransferase (SHMT2) in oral squamous cell carcinoma (OSCC) and its correlation with clinical traits and the prognosis of OSCC patients. Immunochemical staining and Western blotting were used to quantify the expression of SHMT2 and related immune markers in OSCC. Using OSCC microarrays and The Cancer Genome Atlas (TCGA) database, we evaluated the association between SHMT2 and various clinical traits. We found that increased expression of SHMT2 was detected in OSCC and correlated with advanced pathological grade and recurrence of OSCC. By a multivariate Cox proportional hazard model, high expression of SHMT2 was shown to indicate a negative prognosis. In addition, in the OSCC microenvironment, increasing the expression of SHMT2 was associated with high expression levels of programmed cell death-ligand 1 (PD-L1), CKLF-like MARVEL transmembrane domain containing 6 (CMTM6), V-type immunoglobulin domain-containing suppressor (VISTA), B7-H4, Slug, and CD317. In the future, more effort will be required to investigate the role of SHMT2 in the OSCC microenvironment.

Project description:ImportanceDefinitive chemoradiotherapy and upfront surgical treatment are both accepted as the standard of care for advanced-stage oropharyngeal squamous cell carcinoma. However, the optimal primary treatment modality remains unclear.ObjectiveTo evaluate the comparative effectiveness of definitive chemoradiotherapy and upfront surgical treatment for advanced-stage oropharyngeal cancer.Design, setting, and participantsThis retrospective comparative effectiveness analysis used data from the population-based Taiwan Cancer Registry. Included patients were diagnosed with clinical stage III or IV oropharyngeal squamous cell carcinoma from 2007 to 2015 and were identified from the registry. Patients with T4b or N3 disease were excluded. Data were analyzed from June 2019 through December 2020.InterventionsDefinitive chemoradiotherapy or upfront surgical treatment.Main outcomes and measuresThe primary outcome was overall survival, for which data were available through December 31, 2018. Secondary outcomes were progression-free survival, locoregional recurrence-free survival, and distant metastasis-free survival.ResultsAmong 1180 patients, 694 patients (58.8%) were in the definitive chemoradiotherapy group and 486 patients (41.2%) were in the upfront surgical treatment group. The median (interquartile range) follow-up was 3.62 (1.63-5.47) years, and most patients were men (1052 [89.1%] men) with a primary tumor in the tonsils (712 patients [60.3%]), moderately differentiated histology (604 patients [51.2%]), clinical N2 disease (858 patients [72.7%]), and clinical stage IVA disease (938 patients [79.5%]). The mean (SD) age was 54.59 (10.35) years. Primary treatment with an upfront surgical procedure was associated with a decreased risk of death during the study period (hazard ratio [HR], 0.81; 95% CI, 0.69-0.97; P = .02). However, when adjusted for age, subsite, histological grade, and T and N classification, upfront surgical treatment was no longer associated with an increased risk of death during the study period (HR, 0.96; 95% CI, 0.80-1.16; P = .70). Progression-free survival was worse in the group receiving upfront surgical treatment than in the group receiving chemoradiotherapy (HR, 1.64; 95% CI, 1.09-2.46; P = .02), and this difference persisted after adjusting for other factors associated with prognosis (ie, age, tumor subsite, histological grade, and T and N classification) (HR, 1.72; 95% CI, 1.12-2.66; P = .01).Conclusions and relevanceThis study found that definitive chemoradiotherapy was associated with effectiveness that was comparable with that of upfront surgical treatment when adjusted for baseline factors associated with prognosis. These findings suggest that definitive chemoradiotherapy should be considered to avoid accumulating toxic effects associated with surgical treatment and chemoradiotherapy.

Project description:Kidney transplantation (KT) is controversial in patients with pretransplant pulmonary hypertension (PtPH). We aimed to quantify post-KT graft and patient survival as well as survival benefit in recipients with PtPH.MethodsUsing UR Renal Data System (2000-2018), we studied 90 819 adult KT recipients. Delayed graft function, death-censored graft failure, and mortality were compared between recipients with and without PtPH using inverse probability weighted logistic and Cox regression. Survival benefit of KT was determined using stochastic matching and stabilized inverse probability treatment Cox regression.ResultsAmong 90 819 KT recipients, 2641 (2.9%) had PtPH. PtPH was associated with higher risk of delayed graft function (odds ratio, 1.23; 95% CI, 1.10-1.36; P < 0.01), death-censored graft failure (hazard ratio [HR], 1.23; 95% CI, 1.11-1.38; P < 0.01), and mortality (HR, 1.56; 95% CI, 1.44-1.69; P < 0.01). However, patients with PtPH who received a KT had a 46% reduction in mortality (HR, 0.54; 95% CI, 0.48-0.61; P < 0.01) compared with those who remained on the waitlist.ConclusionsAlthough PtPH is associated with inferior post-KT outcomes, KT is associated with better survival compared with remaining on the waitlist. Therefore, KT is a viable treatment modality for appropriately selected patients with PtPH.

Project description:Background: Aspirin use has been associated with improved survival rates in various cancers. However, it remains unclear if aspirin confers a survival benefit on patients with nasopharyngeal carcinoma (NPC). The aim of this study was to assess the associations between aspirin use and survival in different stages of NPC. Methods: This is a 10-year retrospective cohort study of NPC patients. A total of 565 NPC patients were recruited after we performed a 1:4 propensity score match between aspirin users and non-users. Cox regression models with adjusted covariates were employed to evaluate factors that influence the survival rate of NPC patients. Results: The Kaplan-Meier analysis revealed that the overall survival (p < 0.0001) and disease-specific survival (p < 0.0001) rates of 180-day aspirin users increased. Increased survival rates were also observed in 180-day aspirin users with Stages III and IV, T, N1 and 2, and N3 categories. Cox regression models indicated that factors, including aspirin use (univariate: HR = 0.28, 95% CI = 0.14-0.55, p < 0.001; multivariate: HR = 0.23, 95% CI = 0.12-0.46, p < 0.001), were independent prognostic factors for survival. Conclusions: Aspirin use for more than 180 days is associated with an increased survival rate and is a positive independent prognostic factor in NPC.

Project description:BackgroundThere is no clear consensus on the use of aspirin (ASA) in patients with congestive heart failure (CHF) due to its reported interaction with other cardio-prudent medications. The aim was to evaluate the effect of ASA on all-cause mortality and the frequency of hospitalization for heart failure in patients with CHF using meta-analysis, as well as to study the potential variables interacting with this effect.MethodsEligible studies were identified via a PubMed search, the "related article" feature and a manual search of references. Studies were included if they had a study population with CHF of any etiology, compared ASA to no ASA or placebo, and reported one or both of the following outcomes: 1) all-cause mortality and 2) the frequency of hospitalization for heart failure. Data were extracted and verified. We used the inverse variance method in a random-effects model to combine effect sizes.ResultsA total of 14 studies with a combined study population of 64,550 patients were included in the final analysis. All-cause mortality was found to be significantly lower in patients who were taking ASA (P = 0.003). When examining the use of ASA, no significant difference was found in the frequency of hospitalization for heart failure. ASA use was demonstrated to be more beneficial against mortality in studies with a larger percentage of patients on nitrates (P = 0.008) and oral anticoagulants (P = 0.04). A significantly lower rate of hospitalization for heart failure was observed in patients who used oral anticoagulants and ASA concurrently (P = 0.02).ConclusionsASA may have beneficial effects on mortality in patients with heart failure of all etiologies.

Project description:Background: DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is known to function in several types of cancer. In this study, we investigated the expression and clinicopathologic significance of DNA-PKcs in laryngeal squamous cell carcinoma (LSCC). Methods: We conducted a retrospective study of 208 patients with advanced-stage LSCC treated at Sun Yat-sen University Cancer Center, Guangzhou, China. We assessed DNA-PKcs and p16INK4a (p16) status using immunohistochemistry. We examined the association between DNA-PKcs expression and clinicopathologic features and survival outcomes. To evaluate the independent prognostic relevance of DNA-PKcs, we used univariate and multivariate Cox regression models. We estimated overall survival (OS) and distant metastasis-free survival (DMFS) using the Kaplan-Meier method. Results: Immunohistochemical analyses revealed that 163/208 (78.4%) of the LSCC tissue samples exhibited high DNA-PKcs expression. High DNA-PKcs expression was significantly associated with survival outcomes (P = 0.016) and distant metastasis (P = 0.02; chi-squared test). High DNA-PKcs expression was associated with a significantly shorter OS and DMFS than low DNA-PKcs expression (P = 0.029 and 0.033, respectively; log-rank test), and was associated with poor OS in the p16-positive subgroup (P = 0.047). Multivariate analysis identified DNA-PKcs as an independent prognostic indicator of OS and DMFS in all patients (P = 0.039 and 0.037, respectively). Conclusions: Our results suggest that patients with LSCC in whom DNA-PKcs expression is elevated have a higher incidence of distant metastasis and a poorer prognosis. DNA-PKcs may represent a marker of tumor progression in patients with p16-positive LSCC.
