CD8+ T Cells and PD-L1 Expression as Prognostic Indicators in a Low Prevalence of HPV-Associated Oropharyngeal Squamous Cell Carcinoma.

Explore the expression p16, CD8+ TIL, and PD-L1 and its value as prognostic indicators for overall survival (OS) in patients with OPSCC. Data from patients with OPSCC diagnosed from 2012 to 2018 were recovered from medical records and national registry. All available glass slides and slides of immunohistochemistry (IHC) of p16, CD8, and PD-L1 were reviewed. The TME was classified into four types according to the expression pattern of PD-L1 and CD8+TIL. Overall survival (OS) was assessed using the Kaplan-Meier method and Cox regression model analysis. In 160 OPSCC patients, p16 was positive in 27 (16.88%). The density of CD8+ TIL was higher in the p16+ and PD-L1+ groups (p = 0.005, 0.039); however, there was no association between p16 and the status of PD-L1. P16 and CD8+ TIL were significant prognostic factors for better OS (p = 0.007, 0.001), but not PD-L1 status (p = 0.317). Among the four types of TME, carcinoma showed mainly type IV TME (PD-L1-/TIL+), while OPSCCs with type I TME (PD-L1+/TIL+) had the best survival outcome. The positivity of p16 and the density of CD8+ TIL were associated with better OS in OPSCC, while the status of PD-L1 was not significantly related to OS. OPSCC with type I TME (PD-L1+/TIL+) showed the best prognosis of all types of TME.

Diagnostic value of positron emission tomography/computed tomography (PET/CT) in detection of peritoneal carcinomatosis

BackgroundThe diagnosis of peritoneal carcinomatosis is challenging and can be difficult to detect with imaging, especially the detection of small-sized peritoneal lesions. The presence of peritoneal neoplastic spread alters tumour staging and is one of the most significant prognostic indicators in several malignancies, and the purpose of this study was to highlight the diagnostic value of PET/CT in detection of peritoneal carcinomatosis in patients with malignant neoplastic disease.ResultsPET/CT has 76.2% sensitivity, 88.9% specificity, 94.1% PPV, 61.5% NPV and 80% accuracy in detection of peritoneal carcinomatosis. Different patterns of FDG uptake of peritoneal carcinomatosis were found such as focal nodular uptake, diffuse abdominal uptake and liver surface focal or diffuse uptake. From all these different patterns, focal nodular uptake was the most frequent pattern. The best cut-off value of SUVmax was 5 for diagnosis.ConclusionsThe study affirms the significant role of PET/CT in the diagnosis of peritoneal carcinomatosis and its important value in the staging, management and follow-up of patients with secondary peritoneal malignancies, especially in case of unavailable or inappropriate peritoneal biopsy. Therefore, PET/CT could help reduce the number of laparotomies and a better selection of patients who are candidates for adjuvant chemotherapy.

Laparoscopic versus open oncological extended re-resection for incidental gallbladder adenocarcinoma: we can do more than T1/2.

The laparoscopic and open approaches have comparable safety and oncological efficacy to treat early (T1b or T2) stage incidental gallbladder cancer (IGBC). However, their effects on T3 stage or above tumors unclear. Data of IGBC patients who underwent radical re-resection were retrospectively analyzed. Demographic characteristics, surgical variables, and tumor characteristics were evaluated for association with survival. We analyzed retrospectively 201 patients (72 men, 129 women; median age 63years; range, 36-85years). 84 underwent laparoscopic re-resection and 117 underwent open surgery. The 5-year OS post-resection was 74.7%, with a median survival of 74.52months. The median OS (73.92months vs. 77.04months, P = 0.67), and disease-free survival (72.60months vs. 71.09months, P = 0.18) were comparable between the laparoscopic re-resection and open surgery groups. The survival of patients with T1/T2 (median: 85.50months vs. 80.14months; P = 0.67) and T3 (median: 68.56months vs. 58.85months; P = 0.36) disease were comparable between the open re-resection and laparoscopic re-resection groups even after PS matching. Open surgery group lost significantly more blood, while laparoscopic surgery took longer. The postsurgical stay in the laparoscopic re-resection group was significantly shorter. Combined extrahepatic bile duct resection, gallbladder perforation, pT, pStage, histological grade, microscopic liver invasion, status of the resected margin, and adjuvant therapy comprised significant independent prognostic indicators for IGBC. Laparoscopic and open surgery can achieve similar short and long-term outcomes for T3 IGBC; however, careful surgical manipulation is necessary to avoid secondary injuries.

Striatins and STRIPAK complex partners in clinical outcomes of patients with breast cancer and responses to drug treatment.

Striatins (STRNs) family, which contains three multi-domain scaffolding proteins, are cornerstones of the striatins interacting phosphatase and kinase (STRIPAK) complex. Although the role of the STRIPAK complex in cancer has become recognized in recent years, its clinical significance in breast cancer has not been fully established. Using a freshly frozen breast cancer tissue cohort containing both cancerous and adjacent normal mammary tissues, we quantitatively evaluated the transcript-level expression of all members within the STRIPAK complex along with some key interacting and regulatory proteins of STRNs. The expression profile of each molecule and the integrated pattern of the complex members were assessed against the clinical-pathological factors of the patients. The Cancer Genome Atlas (TCGA) dataset was used to evaluate the breast cancer patients' response to chemotherapies. Four human breast cancer cell lines, MDA-MB-231, MDA-MB-361, MCF-7, and SK-BR-3, were subsequently adopted for in vitro work. Here we found that high-level expressions of STRIP2, calmodulin, CCM3, MINK1 and SLMAP were respectively associated with shorter overall survival (OS) of patients. Although the similar pattern observed for STRN3, STRN4 and a contrary pattern observed for PPP2CA, PPP2CB and PPPR1A were not significant, the integrated expression profile of STRNs group and PPP2 group members constitutes a highly significant prognostic indicator for OS [P<0.001, hazard ratio (HR)=2.04, 95% confidence interval (95% CI), 1.36-3.07] and disease-free survival (DFS) (P=0.003, HR=1.40, 95% CI, 1.12-1.75). Reduced expression of STRN3 has an influence on the biological functions including adhesiveness and migration. In line with our clinical findings, the breast cancer cells responded to STRN3 knockdown with changes in their chemo-sensitivity, of which the response is also breast cancer subtype dependent. Our results suggest a possible role of the STRIPAK complex in breast cancer development and prognosis. Among the members, the expression profile of STRN3 presents a valuable factor for assessing patients' responses to drug treatment.

Association between mean platellet volume levels and mortality outcomes in geriatric patients in intensive care

To prospectively evaluate the relationship between Mean Platelet Volume (MPV) levels and short-term mortality outcomes in critically ill patients aged ≥85 years. We hypothesized that abnormal MPV levels could offer actionable insights for predicting mortality risk in this highly vulnerable group, thereby improving therapeutic decision-making processes in the ICU setting. This study included patients aged ≥85 years. The participants were categorized into two groups based on their MPV levels at admission: group 1 (MPV≤12.5, normal range) and group 2 (MPV&gt;12.5, elevated).A comprehensive set of variables, including demographic information, clinical indices, biochemical parameters, and respiratory metrics, were recorded. In a cohort of 475 participants, patients were stratified into two distinct groups based on MPV values: group 1 (n=400, 84.2%) and group 2 (n=75, 15.8%). The mean age was 89 (SD=7.7) and 88 (SD=6.2) years for group 1 and group 2, respectively, with a statistically significant difference (p=0.035). Significant differences were found in key biochemical parameters such as urea (p=0.045) and sodium (p=0.005). The most profound disparity was observed in platelet counts, with a highly significant p-value &lt;0.001. The clinical outcomes showed a substantial divergence in the 30-day mortality rates between the two MPV-based cohorts (p&lt;0.001). Additionally, a higher incidence of sepsis was recorded in the Group 2 (p=0.024). MPV is a significant prognostic indicator for mortality, 30-day mortality, and sepsis incidence, advocating its inclusion in routine clinical assessments to optimize patient care. Routinely accessible platelet indices serve as robust indicators for assessing both morbidity and mortality in critically ill patients.

The IASLC grading system for invasive pulmonary adenocarcinoma: a potential prognosticator for patients receiving neoadjuvant therapy.

Grading system for resected invasive pulmonary adenocarcinoma proposed by the International Association for the Study of Lung Cancer (IASLC) was validated as a strong prognostic indicator. Nonetheless, the efficacy of utilizing such grading system in prognostic assessment of patients receiving neoadjuvant therapy still needs elucidating. A retrospective study was conducted including patients with resected adenocarcinoma following neoadjuvant chemotherapy or targeted therapy from August 2012 to December 2020 in Shanghai Pulmonary Hospital. All the surgical specimens were re-evaluated and graded. The prognostic value of the grading system was further validated. Ultimately, a total of 198 patients were enrolled in this study, and subdivided into three cohorts according to the grading system. There were 13 (6.6%), 37 (18.7%), and 148 (74.7%) patients belonging to Grades 1, 2, and 3, respectively. IASLC grading system demonstrated significant power in prognosis differentiation of the entire cohort [recurrence-free survival (RFS), p < 0.001; overall survival (OS), p < 0.001] and the neoadjuvant chemotherapy and targeted therapy cohorts separately, and was further verified as a significant prognostic indicator for RFS and OS in multivariable Cox analysis. Since the majority of the patients (84.8%) did not achieve major pathologic response (MPR), representing a wide spectrum of survival, the prognostic value of grading system in non-MPR cohort was further evaluated. Similar results were also obtained that IASLC grading system was assessed significant in univariable analysis of RFS (p < 0.001) and univariable analysis of OS (p = 0.001). The prognostic efficacy of pathological evaluation of the residual proportion of pulmonary adenocarcinoma post-neoadjuvant therapy using IASLC grading system was preliminarily verified. Such grading system might assist prognostic evaluation of neoadjuvant cohort other than traditional pathological parameters.

Survival After Breast-Conserving Surgery Compared with that After Mastectomy in Breast Cancer Patients Receiving Neoadjuvant Chemotherapy.

Breast-conserving surgery (BCS) plus radiotherapy (BCS + RT) has been shown to improve survival compared with mastectomy in patients with early breast cancer; however, whether this superiority is maintained in breast cancer patients receiving neoadjuvant chemotherapy (NCT) is unclear. We evaluated and compared the survival outcomes after BCS + RT and mastectomy in Korean women with breast cancer treated with NCT. We evaluated 1641 patients who received NCT before surgery (BCS or mastectomy). We performed propensity score matching to minimize potential bias due to factors other than the surgical method and compared the 5-year, disease-free survival (DFS), distant metastasis-free survival (DMFS), and overall survival (OS) rates before and after exact matching. Among the 1641 patients, 839 (51.1%) underwent BCS + RT and 802 (48.9%) underwent mastectomy. Patients who underwent mastectomy had larger tumors and more frequently had positive nodes. For BCS+RT and mastectomy, the unadjusted 5-year DFS, 5-year DMFS, and 5-year OS rates were 87.0% and 73.1%, 89.5% and 77.0%, and 91.8% and 81.0%, respectively (all p < 0.05 = 0.000). After PSM, 5-year DFS, 5-year DMFS, and 5-year OS rates for BCS + RT and mastectomy were 87.6% and 69.1%, 89.7% and 76.0%, and 89.1% and 75.7%, respectively (all p < 0.05). In both unadjusted and adjusted analyses accounting for various confounding factors, BCS + RT was significantly associated with improved DFS (p < 0.05), DMFS (p < 0.05), and OS (p < 0.05) rates compared with mastectomy. BCS + RT does not impair DFS and OS in patients treated with NCT. Tumor biology and treatment response are significant prognostic indicators. Our results suggest that BCS + RT may be preferred in most breast cancer patients when both BCS and mastectomy are suitable.

Incidence and Associations of Acute Kidney Injury after General Thoracic Surgery: A System Review and Meta-Analysis.

(1) Background: Acute kidney injury (AKI) is related to adverse outcomes in critical illness and cardiovascular surgery. In this study, a systematic literature review and meta-analysis was carried out to evaluate the incidence and associations of AKI as a postoperative complication of thoracic (including lung resection and esophageal) surgical procedures. (2) Methods: Adopting a systematic strategy, the electronic reference databases (PubMed, EMBASE, and Cochrane Library) were searched for articles researching postoperative renal outcomes that were diagnosed using RIFLE, AKIN or KDIGO consensus criteria in the context of a thoracic operation. A random-effects model was applied to estimate the incidence of AKI and, where reported, the pooled relative risk of mortality and non-renal complications after AKI. The meta-analysis is registered in PROSPERO under the number CRD42021274166. (3) Results: In total, 20 studies with information gathered from 34,826 patients after thoracic surgery were covered. Comprehensively, the incidence of AKI was estimated to be 8.8% (95% CI: 6.7−10.8%). A significant difference was found in the mortality of patients with and without AKI (RR = 2.93, 95% CI: 1.79−4.79, p < 0.001). Additionally, in patients experiencing AKI, cardiovascular and respiratory complications were more common (p = 0.01 and p < 0.001, respectively). (4) Conclusions: AKI is a common complication associated with adverse outcomes following general thoracic surgery. An important issue in perioperative care, AKI should be considered as a highly significant prognostic indicator and an attractive target for potential therapeutic interventions, especially in high-risk populations.

BackgroundAs an integral part of the tumor microenvironment (TME), tumor-associated neutrophils play a crucial role in tumor development. The objective of this study was to investigate the plasticity of tumor-associated...

Stage-Specific Survival in Breast Cancer in Chinese and White Women: Comparative Data Analysis.

Stage-specific survival, according to the eighth edition of the American Joint Committee on Cancer (AJCC) pathological prognostic staging (PPS) on breast cancer (BC), between Chinese and White American women remains unclear. This study aimed to assess stage-specific survival in BC between Chinese and White American women according to the eighth AJCC PPS. We included Chinese and White American women with BC diagnosed between 2010 and 2018 from the Surveillance, Epidemiology, and End Results database. A chi-square test, the Kaplan-Meier method, a receiver operating characteristic (ROC) curve, and multivariate Cox proportional hazards models were used for data analysis. We included 376,818 individuals in this study: 369,522 White American and 7296 Chinese. Of them, 149,452 (39.7%) migrated from the seventh AJCC anatomic staging (AS) to the eighth AJCC PPS, 22,516 (6.0%) were upstaged, and 126,936 (33.7%) were downstaged. With a median follow-up duration of 44 months, the 5-year overall survival and cancer-specific survival (CSS) for the entire group were 87.4% and 95.9%, respectively. The seventh AJCC AS (P<.001) and the eighth AJCC PPS (P<.001) could significantly predict the survival outcomes of BC, and multivariate analysis revealed that both staging systems were significant prognostic indicators of CSS. The ROC curve revealed that the PPS had a better discriminating ability than the AS (area under the curve [AUC] 0.769 vs 0.753, P<.001). Similar trends were observed after stratification by the 2 ethnic groups. The eighth AJCC PPS had better discriminating ability than the seventh AJCC AS among both White American (AUC 0.769 vs 0.753, P<.001) and Chinese patients (AUC 0.790 vs 0.776, P<.001). In the seventh AJCC AS, Chinese women had better CSS in stage IA (P=.02), stage IIA (P=.005), and stage IIIB (P=.04) disease than White American women, but no significant CSS was observed in stage IB, IIB, IIIA, and IIIC disease between the 2 ethnic groups. Regarding the eighth AJCC PPS, Chinese women had better CSS in stage IA (P=.002) and IIIA (P=.046) disease than White American women, and CSS was similar in Chinese and White American women in other substages. The eighth AJCC PPS has a similar discriminative ability between White American and Chinese individuals with BC compared with the seventh AJCC AS. Therefore, the eighth AJCC PPS is also applicable to Chinese individuals with BC.

BIOS-05. SANGER SEQUENCING AND COPY-NUMBER ALTERATION ANALYSIS WITH MLPA CAN CLINICALLY CLASSIFY IDH-WILD-TYPE LOWER-GRADE ASTROCYTOMA

Abstract The IDH-wild-type lower-grade astrocytomas are a heterogeneous entity. According to 2021 WHO classification, IDH-wild-type astrocytomas with any of the following factors show poor prognosis: combination of chromosome 7 gain and 10 loss (+7/-10), and/or EGFR amplification, and/or TERT promoter (TERTp) mutation. Multiplex ligation-dependent probe amplification (MLPA) can detect copy number alterations with a reasonable cost. The purpose of this study was to find precise and cost-effective method for stratifying the prognosis of IDH-wild-type astrocytomas. Sanger sequencing, MLPA, and quantitative methylation-specific PCR were performed for 42 IDH-wild-type lower-grade astrocytomas surgically treated at Kyoto University Hospital, and overall survival was analyzed for 40 patients. Of the 42 IDH-wild-type astrocytomas, 21 were classified as grade 4 in 2021 WHO classification and all of them had either TERTp mutation or EGFR amplification. Kaplan-Meier analysis confirmed the prognostic significance of 2021 WHO Classification, and WHO grade was also prognostic. Cox regression hazard model identified PTEN loss and PDGFRA amplification as independent significant prognostic indicators (Risk ratio of 9.75, p&amp;lt; 0.001 and 13.9, p=0.002). The classification recommended by 2021 WHO Classification could be completed using Sanger sequencing and MLPA. Survival analysis revealed PTEN and PDGFRA were significant prognostic factors for IDH-wild-type lower-grade astrocytomas.

ARL11 correlates with the immunosuppression and poor prognosis in breast cancer: A comprehensive bioinformatics analysis of ARL family members

ADP-ribosylation factor-like protein (ARL) family members (ARLs) may regulate the malignant phenotypes of cancer cells. However, relevant studies on ARLs in breast cancer (BC) are limited. In this research, the expression profiles, genetic variations, and prognostic values of ARLs in BC have been systematically analyzed for the first time using various databases. We find that ARLs are significantly dysregulated in BC according to the TCGA database, which may result from DNA methylation and copy number alteration. Prognostic analysis suggests that ARL11 is the most significant prognostic indicator for BC, and higher ARL11 predicts worse clinical outcomes for BC patients. Further functional enrichment analysis demonstrates that ARL11 enhances the immunosuppression in BC, and dysregulation of ARL11 is significantly associated with immune infiltration in various types of cancer. Our results demonstrate the potential of ARL11 as an immune therapeutic target for BC.

Hyperfibrinolysis and fibrinolysis shutdown in patients with traumatic brain injury

Traumatic brain injury (TBI) is associated with coagulation/fibrinolysis disorders. We retrospectively evaluated 61 TBI cases transported to hospital within 1 h post-injury. Levels of thrombin-antithrombin III complex (TAT), D-dimer, and plasminogen activator inhibitor-1 (PAI-1) were measured on arrival and 3 h, 6 h, 12 h, 1 day, 3 days and 7 days after injury. Multivariate logistic regression analysis was performed to identify prognostic factors for coagulation and fibrinolysis. Plasma TAT levels peaked at admission and decreased until 1 day after injury. Plasma D-dimer levels increased, peaking up to 3 h after injury, and decreasing up to 3 days after injury. Plasma PAI-1 levels increased up to 3 h after injury, the upward trend continuing until 6 h after injury, followed by a decrease until 3 days after injury. TAT, D-dimer, and PAI-1 were elevated in the acute phase of TBI in cases with poor outcome. Multivariate logistic regression analysis showed that D-dimer elevation from admission to 3 h after injury and PAI-1 elevation from 6 h to 1 day after injury were significant negative prognostic indicators. Post-TBI hypercoagulation, fibrinolysis, and fibrinolysis shutdown were activated consecutively. Hyperfibrinolysis immediately after injury and subsequent fibrinolysis shutdown were associated with poor outcome.

Evaluation of the serum C-reactive protein-albumin ratio andits relationship with disease severity IN alopecia areata: Aprospective case-control study.

Alopecia areata (AA) is an autoimmune and inflammatory disease characterized by localized or diffuse non-scarring hair loss. The serum C-reactive protein (CRP)/albumin ratio (CAR) is a novel inflammatory marker and a significant prognostic indicator in several diseases. We aimed to explore CAR in AA patients and healthy controls and analyze the possible correlation between CAR and disease severity. The present study was conducted with 65 eligible AA patients and 65 age- and gender-matched healthy controls. Disease severity was analyzed based on the Severity of Alopecia Tool (SALT) score. The CAR score was calculated by dividing serum CRP by the albumin content in both patient and healthy control groups. 56.9% of the patients were male and 43.1% were female, and the mean age was 31.93 ± 9.67. The patient group'mean CAR level (0.42 ± 0.3) was statistically higher than that of the healthy controls (0.07 ± 0.04), (p < 0.05). There were positive correlations between disease severity, CAR (r=0.65; p < 0.01), and CRP (r=0.66; p < 0.01), while the correlation between disease severity and albumin was negative (r=-0.56; p < 0.01). In the receiver operating characteristic analysis conducted on disease severity, the area under the curve was 0.16 for albumin, 0.92 for CRP, and 0.95 for CAR. The optimum CAR for AA severity was 0.38 with 87% sensitivity and 92% specificity. In the study, we determined that the CAR was higher in AA patients when compared to the control group, and the elevation was associated with disease severity. The present study findings demonstrated that alopecia areata was associated with systemic inflammation, and CAR is a useful inflammatory marker in AA patients.

Multidimensional characteristics, prognostic role, and preoperative prediction of peritoneal sarcomatosis in retroperitoneal sarcoma.

Peritoneal sarcomatosis (PS) could occur in patients with retroperitoneal sarcomas (RPS). This study aimed to expand the understanding of PS on its characteristics and prognostic role, and develop a nomogram to predict its occurrence preoperatively. Data of 211 consecutive patients with RPS who underwent surgical treatment between 2011 and 2019 was retrospectively reviewed. First, the clinicopathological characteristics of PS were summarized and analyzed. Second, the disease-specific survival (DSS) and recurrence-free survival (RFS) of patients were analyzed to evaluate the prognostic role of PS. Third, preoperative imaging, nearly the only way to detect PS preoperatively, was combined with other screened risk factors to develop a nomogram. The performance of the nomogram was assessed. Among the 211 patients, 49 (23.2%) patients had PS with an incidence of 13.0% in the primary patients and 35.4% in the recurrent patients. The highest incidence of PS occurred in dedifferentiated liposarcoma (25.3%) and undifferentiated pleomorphic sarcoma (25.0%). The diagnostic sensitivity of the preoperative imaging was 71.4% and its specificity was 92.6%. The maximum standardized uptake value (SUVmax) was elevated in patients with PS (P<0.001). IHC staining for liposarcoma revealed that the expression of VEGFR-2 was significantly higher in the PS group than that in the non-PS group (P = 0.008). Survival analysis (n =196) showed significantly worse DSS in the PS group than in non-PS group (median: 16.0 months vs. not reached, P < 0.001). In addition, PS was proven as one of the most significant prognostic predictors of both DSS and RFS by random survival forest algorithm. A nomogram to predict PS status was developed based on preoperative imaging combined with four risk factors including the presentation status (primary vs. recurrent), ascites, SUVmax, and tumor size. The nomogram significantly improved the diagnostic sensitivity compared to preoperative imaging alone (44/49, 89.8% vs. 35/49, 71.4%). The C-statistics of the nomogram was 0.932, and similar C-statistics (0.886) was achieved at internal cross-validation. PS is a significant prognostic indicator for RPS, and it occurs more often in recurrent RPS and in RPS with higher malignant tendency. The proposed nomogram is effective to predict PS preoperatively.

Hospitalisation Is Prognostic of Survival in Chronic Thromboembolic Pulmonary Hypertension.

This analysis investigated the prognostic value of hospitalisation in chronic thromboembolic pulmonary hypertension (CTEPH) using data from the Czech Republic, wherein pulmonary endarterectomy (PEA) was the only targeted treatment option until 2015. Using a landmark method, this analysis quantified the association between a first CTEPH-related hospitalisation event occurring before 3-, 6-, 9-, and 12-month landmark timepoints and subsequent all-cause mortality in adult CTEPH patients diagnosed between 2003 and 2016 in the Czech Republic. Patients were stratified into operable and inoperable, according to PEA eligibility. CTEPH-related hospitalisations were defined as non-elective. Hospitalisations related to CTEPH diagnosis, PEA, balloon pulmonary angioplasty, or clinical trial participation were excluded. Of 436 patients who survived to ≥3 months post diagnosis, 309 were operable, and 127 were inoperable. Sex- and age-adjusted hazard ratios (HRs) showed CTEPH-related hospitalisation was a statistically significant prognostic indicator of mortality at 3, 9, and 12 months in inoperable patients, with an approximately 2-fold increased risk of death in the hospitalisation group (HRs [95% CI] ranging from 1.98 [1.06–3.70] to 2.17 [1.01–4.63]). There was also a trend of worse survival probabilities in the hospitalisation groups for operable patients, with the difference most pronounced at 3 months, with a 76% increased risk of death (adjusted HR [95% CI] 1.76 [1.15–2.68]). This first analysis on the prognostic value of CTEPH-related hospitalisations demonstrates that a first CTEPH-related hospitalisation is prognostic of mortality in CTEPH, particularly for inoperable patients. These patients may benefit from medical and/or interventional therapy.

The prognostic nutritional index, an independent predictor of overall survival for newly diagnosed follicular lymphoma in China.

ObjectiveThe prognostic nutritional index (PNI) is an important prognostic factor for survival outcomes in various hematological malignancies. The current study focused on exploring the predictive value of the PNI in newly diagnosed follicular lymphoma (FL) in China.Materials and methodsThe clinical indicators and follow-up data of 176 patients who received chemotherapy or immunotherapy combined with chemotherapy with FL in our hospital from January 2016 to March 2022 were retrospectively analyzed. Cox proportional hazard model was used for univariate and multivariate analyses. Kaplan–Meier curves were used to calculate survival rates and draw survival curves. The log-rank test was applied to compare differences between groups.ResultsThe optimal cut-off value of PNI was 44.3. All patients were divided into a high PNI group (>44.3) and a low PNI group (≤44.3). The low PNI group had a low CR rate and a high risk of death, with a tendency toward POD24, and Both OS and PFS were worse than those in the high PNI group. PNI was able to predict OS and PFS in FL patients and was the only independent predictor of OS (P = 0.014 HR 5.024; 95%CI 1.388∼18.178) in multivariate analysis. PNI could re-stratify patients into groups of high FLIPI score, high FLIPI2 score, no POD24, and rituximab combined with chemotherapy. Moreover, integrating PNI into the FLIPI and FLIPI2 models improved the area under the curve (AUC) for more accurate survival prediction and prognosis.ConclusionPNI is a significant prognostic indicator for newly diagnosed FL in China that can early identify patients with poor prognosis and guide clinical treatment decisions.

Prognostic significance of dysplasia associated with oral squamous cell carcinoma in patients undergoing surgery with curative intent

The aim of this study was to evaluate the prognostic significance of dysplasia in patients undergoing primary surgery with curative intent in the treatment of oral squamous cell carcinoma (OSCC). This study specifically aimed to demonstrate the effect of dysplasia on local recurrence, disease specific survival (DSS) and overall survival (OS). Data collection for 833 patients with OSCC undergoing treatment for curative intent was undertaken retrospectively for the period of February 2006 to May 2020. Analysis of any association between known clinicopathological prognostic categorical variables with respect to dysplasia was undertaken using the chi squared test. A Kaplan-Meier analysis was performed to demonstrate the impact of dysplasia on DSS and OS, and Cox’s proportional-hazards model deployed to obtain hazard ratios associated with dysplasia and the outcomes of interest. Dysplasia was statistically significant in predicting disease specific and overall survival in patients undergoing primary surgery for OSCC (DSS p<0.001, HR 0.577; 95%CI 0.428 to 0.777), OS p<0.001 HR 0.691; 95%CI 0.562 to 0.850) with the absence of dysplasia predicting poorer outcomes. The absence of dysplasia correlated with pathological higher T and N stage, increased categorised depth of tumour invasion, non-cohesive invasive front, lymphovascular invasion, perineural invasion, extranodal extension and increased modified Glasgow Prognostic Score. No significant prognostic relationship was attributable to the presence of dysplasia at a surgical margin. The absence of dysplasia appeared to be a significant independent prognostic indicator for patients with OSCC. The presence or absence of dysplasia may provide a heuristic means of stratifying OSCC primary lesions in terms of disease hostility.

Deformation analysis in advanced chronic kidney disease: an important prognostic indicator

Abstract Background Chronic kidney disease (CKD) is associated with a higher incidence of cardiovascular manifestations, particularly in patients with advanced renal impairment on long-term dialysis. Cardiac deformation analysis, assessed by speckle tracking echocardiography has been shown to be a significant prognostic index in various specific populations. Objective To assess the prognostic value of deformation analysis measurements including both systolic parameters as left ventricular (LV) global longitudinal strain, and diastolic indices as left atrial (LA) strain, in patients with end-stage renal disease. Methods We enrolled 67 patients (mean age 62.3±11.8, 65.7% men) with end-stage renal disease. Patients with a confirmed diagnosis of pre/existing cardiac conditions, such as obstructive coronary artery disease, heart failure, severe arrhythmias or severe valvular disease were excluded from the study. A comprehensive transthoracic echocardiography study was performed at baseline. All images were stored digitally and subsequent analysis was performed offline. LV global longitudinal strain (GLS) and LA strain were calculated semi-automatically using dedicated software. The primary endpoints of the study were major adverse cardiovascular events such as all-cause mortality, cardiovascular mortality, myocardial infarction, and hospitalizations for cardiac adverse events. The median follow-up was five years. Results The study population had normal or mildly impaired systolic function with a mean LV ejection fraction (EF) of 49.17% (±10.41) while 70% of patients had reduced LV GLS, mean 14.35% (±4.49). Regarding LA parameters, 50% of our cohort had impaired LA strain: mean LA reservoir, LA conduit, and LA contractile reserve were 24.11% (±12.61), 10.56% (±5.88), and 13.60% (±9.15) respectively. The 5-year cumulative event-free survival was 58.2% (±6.7), while 30% of major events occurred in the first 2 years after baseline. Age had a moderate correlation with poor prognosis (p=0.013). Of the echocardiographic parameters LV EF, LV GLS, the conduit phase of LA strain, LA volume and various doppler parameters related to diastolic function, such as mitral E/A ratio and late mitral diastolic velocity A, were found to have a significant negative association with total prognosis (p=0.003, p=0.02, p=0.048, p=0.045, p=0.008, and p=0.017 respectively). Logistic regression analysis showed that of the different echocardiographic parameters LV EF, LV GLS, and the conduit phase of LA strain were significantly associated with the overall prognosis (p=0.009, p=0.007, p=0.05). The conduit element of LA strain was the strongest predictor among them (OR=0.77 p=0.04). Conclusion Left ventricular systolic and diastolic dysfunction is a significant prognostic indicator in patients with end stage renal disease. Assessing cardiac mechanics with speckle tracking echocardiography could provide valuable information in this specific population. Funding Acknowledgement Type of funding sources: None.

Identification of TLN1 as a prognostic biomarker to effect cell proliferation and differentiation in acute myeloid leukemia

The protein Talin1 encoded by the TLN1 gene is a focal adhesion-related protein that binds to various cytoskeletal proteins and plays an important role in cell adhesion and movement. Recent studies have shown that it is overexpressed in prostate cancer, liver cancer, and oral squamous cell carcinoma, and is closely related to tumor progression and metastasis. This study integrated bioinformatics and functional analysis to reveal the prognosis and potential functions of TLN1 in AML. The results showed that the expression level of TLN1 was abnormally increased in AML and localized in the cell membrane and cytoplasm, and TLN1 is a significant prognostic indicator of overall survival (OS). Enrichment analysis of related genes showed that TLN1 is related to neutrophil mediated immunity, neutrophil activation and may regulate important signal pathways in hematological tumors including tyrosine kinase receptor, FLT3 and PIK3/AKT. The PPI network shows that TLN1 and MYH9 may be involved in the process of AML tumors together with PIP5K1C, ROCK1, S100A4, MY01A and WAC. Immune infiltration analysis explains that TLN1 is associated with multiple immune cells and may be an important immune marker in AML. Furthermore, molecular biology experiments confirmed that TLN1 is related to the proliferation, differentiation and cycle of AML cells. Silencing TLN1 can inhibit the proliferation of AML cells and promote differentiation through the Talin1/P-AKT/CREB signaling pathway.
