Outcome of Allogeneic Hematopoietic Stem Cell Transplantation in a Child with Myelodysplastic Neoplasm with Complex Karyotype and ETV6 Variant: Challenges in Treatment

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only treatment with the potential for cure in patients with myelodysplastic neoplasm (MDS). Nevertheless, disease relapse is the main cause of treatment failure. Due to the rarity of childhood MDS (cMDS), there are few studies showing the impact of cytogenetic alterations and genetic variants on outcomes of allo-HSCT, mainly focusing on clonal chromosomal evolution (CCE) during relapse post-transplant. Here, we describe a 3-year-old boy with cMDS-IB, who evolved to MDS/AML. At diagnosis, the patient showed a complex karyotype with chromosomal abnormalities not yet reported together in the same clone, and likely a pathogenic variant in the ETV6 gene. The patient was treated with HLA-matched sibling HSCT, but unfortunately relapsed after HSCT with clonal cytogenetic evolution. This unfavorable outcome suggests that the treatment of pediatric MDS associated with predictive factors of poor prognosis, such as complex karyotype and ETV6 variant remains a challenge.

Could the mitotic count improve personalized prognosis in melanoma patients?

A number of studies have indicated that the mitotic rate may be a predictive factor for poor prognosis in melanoma patients. The aim of this study was to investigate whether the mitotic rate is associated with other prognostic clinical and anatomopathological characteristics. After adjusting for other anatomopathological characteristics, we then verified the prognostic value of the number of mitoses, determining in which population subgroup this variable may have greater prognostic significance on 3-year mortality. The Veneto Cancer Registry (Registro Tumori del Veneto-RTV), a high-resolution population-based dataset covering the regional population of approximately 4.9 million residents, served as the clinical data source for the analysis. Inclusion criteria included all incident cases of invasive cutaneous malignant melanoma recorded in the RTV in 2015 (1,050 cases) and 2017 (1,205 cases) for which the number of mitoses was available. Mitotic classes were represented by Kaplan-Meier curves for short-term overall survival. Cox regression calculated hazard ratios in multivariable models to evaluate the independent prognostic role of different mitotic rate cut-offs. The results indicate that the mitotic rate is associated with other survival prognostic factors: the variables comprising the TNM stage (e.g., tumor thickness, ulceration, lymph node status and presence of metastasis) and the characteristics that are not included in the TNM stage (e.g., age, site of tumor, type of morphology, growth pattern and TIL). Moreover, this study demonstrated that, even after adjusting for these prognostic factors, mitoses per mm2 are associated with higher mortality, particularly in T2 patients. In conclusion, these findings revealed the need to include the mitotic rate in the histological diagnosis because it correlates with the prognosis as an independent factor. The mitotic rate can be used to develop a personalized medicine approach in the treatment and follow-up monitoring of melanoma patients.

Preoperative serum cholinesterase as a prognostic factor in patients with colorectal cancer

AbstractAimSerum cholinesterase (ChE) levels are considered to reflect nutritional status. Although ChE has been well documented as a prognostic factor for some cancers, no clear consensus on its use for colorectal cancer (CRC) has been reached. The aim of this study was to investigate the relationship between preoperative serum ChE and postoperative long‐term prognosis in CRC patients.MethodsA total of 1053 CRC patients who underwent curative surgery were included in this study. The correlations between the preoperative ChE value and overall survival (OS) or cancer‐specific survival (CSS) were assessed. By dividing patients into two groups according to their ChE value, OS and CSS were compared between the groups.ResultsMultivariate analysis revealed that the continuous ChE value was a significant predictor of OS (hazard ratio, 0.996; 95% CI, 0.993–0.998; p = 0.002) and CSS (hazard ratio, 0.994; 95% CI, 0.991–0.998; p = 0.001), independent of other variables. The low‐ChE (≤234 U/L) group had a significantly poorer prognosis than the high‐ChE (>234 U/L) group for both OS (5‐year OS for low ChE and high ChE: 79.8% and 93.3%, respectively; p < 0.001) and CSS (5‐year CSS for low ChE and high ChE: 84.8% and 95.6%, respectively; p < 0.001).ConclusionsLower preoperative serum ChE levels are a predictive factor of poor prognosis for CRC patients. As serum ChE levels can be measured quickly and evaluated easily, ChE could become a useful marker for predicting the postoperative long‐term outcomes of CRC patients.

Prognostic factors for overall survival of conventional osteosarcoma of the appendicular skeleton.

The aim of this study is to determine the predictors of overall survival (OS) and predictive factors of poor prognosis of conventional high-grade osteosarcoma of the limbs in a single-centre in South Africa. We performed a retrospective cross-sectional analysis to identify the prognostic factors that predict the OS of patients with histologically confirmed high-grade conventional osteosarcoma of the limbs over ten years. We employed the Cox proportional regression model and the Kaplan-Meier method for statistical analysis. This study comprised 77 patients at a three-year minimum follow-up. The predictors of poor OS were: the median age of ≤ 19 years (hazard ratio (HR) 0.96; 95% confidence interval (CI) 0.92 to 0.99; p = 0.021); median duration of symptoms ≥ five months (HR 0.91; 95% CI 0.83 to 0.99; p < 0.037); metastasis at diagnosis (i.e. Enneking stage III) (HR 3.33; 95% CI 1.81 to 6.00; p < 0.001); increased alkaline phosphatase (HR 3.28; 95% CI 1.33 to 8.11; p < 0.010); palliative treatment (HR 7.27; 95% CI 2.69 to 19.70); p < 0.001); and amputation (HR 3.71; 95% CI 1.12 to 12.25; p < 0.032). In contrast, definitive surgery (HR 0.11; 95% CI 0.03 to 0.38; p < 0.001) and curative treatment (HR 0.18; 95% CI 0.10 to 0.33; p < 0.001) were a protective factor. The Kaplan-Meier median survival time was 24 months, with OS of 57.1% at the three years. The projected five-year event-free survival was 10.3% and OS of 29.8% (HR 0.76; 95% CI 0.52 to 1.12; p = 0.128). In this series of high-grade conventional osteosarcoma of the appendicular skeleton from South Africa, 58.4% (n = 45) had detectable metastases at presentation; hence, an impoverished OS of five years was 29.8%. Large-scale future research is needed to validate our results.

High HER2 Intratumoral Heterogeneity Is a Predictive Factor for Poor Prognosis in Early-Stage and Locally Advanced HER2-Positive Breast Cancer.

Breast cancer tumors frequently have intratumoral heterogeneity (ITH). Tumors with high ITH cause therapeutic resistance and have human epidermal growth factor receptor 2 (HER2) heterogeneity in response to HER2-targeted therapies. This study aimed to investigate whether high HER2 heterogeneity levels were clinically related to a poor prognosis for HER2-targeted adjuvant therapy resistance in primary breast cancers. This study included patients with primary breast cancer (n = 251) treated with adjuvant HER2-targeted therapies. HER2 heterogeneity was manifested by the shape of HER2 fluorescence in situ hybridization amplification (FISH) distributed histograms with the HER2 gene copy number within a tumor sample. Each tumor was classified into a biphasic grade graph (high heterogeneity [HH]) group or a monophasic grade graph (low heterogeneity [LH]) group based on heterogeneity. Both groups were evaluated for disease-free survival (DFS) and overall survival (OS) for a median of ten years of annual follow-up. Of 251 patients with HER2-positive breast cancer, 46 (18.3%) and 205 (81.7%) were classified into the HH and LH groups, respectively. The HH group had more distant metastases and a poorer prognosis than the LH group (DFS: p < 0.001 (HH:63% vs. LH:91% at 10 years) and for the OS: p = 0.012 (HH:78% vs. LH:95% at 10 years). High HER2 heterogeneity is a poor prognostic factor in patients with HER2-positive breast cancer. A novel approach to heterogeneity, which is manifested by the shape of HER2 FISH distributions, might be clinically useful in the prognosis prediction of patients after HER2 adjuvant therapy.

Chronic kidney disease as a predictive factor for poor prognosis in traumatic brain injury among older adults: a case-control study

ObjectiveTraumatic brain injury (TBI) is a highly prevalent neurological disorder that affects a gradually increasing proportion of older adults. Chronic kidney disease (CKD) significantly contributes to global years of life lost, with an estimated one-tenth of the global population affected by CKD. However, it remains unclear whether CKD impacts TBI prognosis. We conducted a case-control study to investigate the clinical outcomes of TBI patients with or without CKD comorbidity and identified the risk factors associated with a poor prognosis.MethodsFrom January 2017 through April 2023, 11 patients with TBI and CKD were included, and 27 control TBI cases with normal kidney function were matched by age, gender, and admission Glasgow Coma Scale (GCS) score as the control group.ResultsThe CKD TBI group had a significantly lower GCS score upon discharge (7.1 ± 5.9) compared to the non-CKD TBI group (13.1 ± 2.6) (p &amp;lt; 0.01). ICU stay time and hospitalization expenses were higher in the CKD group than the non-CKD group, though there were no statistical differences. Additionally, patients in the CKD TBI group had a higher frequency of hospital-acquired infections (54.4%) compared with those in the non-CKD TBI group (7.4%) (p &amp;lt; 0.01). The two groups exhibited no differences in hemoglobin levels, albumin levels, or coagulation function. Logistic regression analysis showed that advanced age, low admission GCS score, elevated blood urea, and creatinine levels were associated with a poor neurological prognosis.ConclusionTBI patients comorbid with CKD have a poorer prognosis than those with normal kidney function.

TSPO is a novel biomarker for prognosis that regulates cell proliferation through influencing mitochondrial functions in HCC

The disorder of mitochondrial functions plays a key role in oncogenesis. It is known that TSPO (18-kDa translocator protein) lies in a peculiar location at the interface between the mitochondria and the cytosol. TSPO is found in many types of tissues and is associated with multiple cellular processes, including apoptosis, cell proliferation and the regulation of mitochondria. However, the involvement of TSPO in hepatocellular carcinoma (HCC) remains unclear. In this study, we found that TSPO is upregulated in HCC tissue and is associated with poor differentiation and poor survival. Multivariate analyses showed that TSPO was an independent predictive factor for poor prognosis in HCC patients. For the first time, we provided evidence that TSPO knockdown suppressed HCC cell proliferation in vitro. Hence, TSPO knockdown-induced apoptosis by disturbing mitochondrial function by enhancing the formation of reactive oxygen species (ROS) and decreasing the mitochondrial membrane potential (ΔΨm). An assay exploring the underlying mechanism revealed that TSPO knockdown modulated apoptotic regulatory proteins by regulating the ERK signaling pathway. Through a functional assay and an in vivo mouse model, the anti-cancer effect of PK11195, a specific ligand of TSPO, on HCC was revealed. In summary, TSPO may potentially serve as a prognostic biomarker, and TSPO might be a potential therapeutic target for HCC.

TESC acts as a prognostic factor and promotes epithelial-mesenchymal transition progression in esophageal squamous carcinoma

BackgroundTescalcin (TESC) is a critical regulator of cell differentiation and growth, promoting malignant progression in various tumors. However, the role of TESC in esophageal squamous carcinoma (ESCC) remains unclear. MethodsImmunohistochemistry (IHC), quantitative real-time PCR (qRT-PCR), and western blot were utilized to identify the difference in TESC expression between ESCC tissues and normal tissues adjacent to the carcinoma. The relationship between TESC and several clinicopathological features was shown by the chi-square test. Log-rank analysis and Cox regression were used to detect the relationship between TESC and the prognosis in ESCC. Clone formation and cell count kit-8 (CCK-8) were applied to detect the impact of TESC on ESCC proliferation. Wound healing assay and transwell assay were used to confirm the influence of TESC on the invasion and migration. Spearman correlation coefficient was used to describe the correlation between TESC and epithelial-mesenchymal transition (EMT)-related protein expression in ESCC. Western blot was used to detect the effect of TESC on the expression of E-cadherin, N-cadherin, and Vimentin as well as AKT signaling pathway. Xenograft tumors were developed to test the pro-tumorigenic impacts of TESC in vivo. ResultsTESC was upregulated expression in ESCC tissues and was linked to poorer prognosis and worse tumor infiltration, TNM stage, and lymph node metastasis. Meanwhile, TESC was able to act as an independent prognostic factor in ESCC. TESC promoted tumor cell proliferation, invasion, migration, EMT progression, and activated the phosphorylation of the AKT pathway. Furthermore, TESC knockdown inhibited the growth of carcinoma in vivo. ConclusionTESC is a predictive factor for poor prognosis in ESCC and may provide a new strategy for ESCC treatment.

Preoperative hysteroscopy shortened progression-free survival in advanced FIGO stage in endometrial cancer: Ten year analysis.

To investigate the impact of preoperative hysteroscopy on progression-free survival (PFS) and disease-specific survival (DFS), and to explore the factors which contribute to poor clinical outcomes between hysteroscopy and dilation and curettage (D&C) in endometrial cancer (EC). A retrospective study was designed by collecting data from women diagnosed with EC through hysteroscopy or D&C from January 2010 to December 2019 in a tertiary hospital in China. A propensity score was used for 1:1 matching of advanced stage patients. Univariate and multivariate analysis were conducted to determine whether hysteroscopy was a prognostic factor in EC and to identify factors associated with its impact on PFS and DFS in different subgroups. Overall, 543 and 272 women who underwent D&C and hysteroscopy, respectively were included. Compared to D&C, preoperative hysteroscopy was related to reduced PFS and DFS, with a hazard ratio (HR) of 1.904 and 3.905, respectively. Hysteroscopy contributed to an increased risk of positive wash cytology (48.27% vs 24.13%), recurrence (48.28% vs 20.69%) and shorter PFS after matching in FIGO Stage I-IV EC, while there was no significance in positive ascites cytology (14.04% vs 13.45%), PFS and DFS in FIGO Stage I EC. Hysteroscopy was an independent predictive factor for poor prognosis in EC. Hysteroscopy appeared to be a safe diagnostic method as D&C in FIGO Stage I EC but was a risk factor for increased recurrence and reduced PFS in advanced stage disease. Its impact on DFS is uncertain.

Left-Sided Colon Cancer and Right-Sided Colon Cancer: Are They the Same Cancer or Two Different Entities?

Background Colon cancer is one of the most common cancers in the world and one of the main causes of cancer-related deaths. In Morocco, it occupies the first place among digestive cancers. Right-sided and left-sided colon cancers have different embryological, epidemiological, pathological, genetic, and clinical characteristics. This distinction leads to differences in the evolution and prognosis of the disease. This study aimed to identify epidemiological factors and clinical and pathological characteristics that can influence perioperative and prognostic outcomes in patients with right-sided colon cancer compared to those with left-sided colon cancer. Methodology We conducted a retrospective cohortstudy over a period of nine years from January 2012 until December 2020. We included 277 patients divided into two groups, namely, right colon cancer (group 1) (n = 99) and left colon cancer (group 2) (n = 178). Results The average age of our series was 57.4 years, with extremes ranging from 19 to 89 years old (SD = ±13.6451 years). The average age in the right colon group was 55.97 (SD = ±13.341 years). The average age in the left colon group was 58.18 (SD = ±13.69 years). The male gender had a predominance, with a sex ratio of 1.3 for both groups. Among the patients in group 2, 65% showed lymph node involvement on the CT scan, whereas only 34% of patients in group 1 displayed the same condition. The recurrence rate in the right-sided colon cancer group was 22.2% compared to 24.9% in the left-sided group. The five-year overall survival was estimated for the right-sided and left-sided colon cancer groups at 87% and 96.5%, respectively. In patients with stage III and IV cancer, overall survival was better for those who underwent surgery for left-sided colon cancer compared to those who underwent surgery for right-sided colon cancer (p = 0.029). In the case of vascular emboli or involvement of the perineural sheath, there was no significant difference in overall survival (p = 0.446 and p = 0.655, respectively). The three-month survival without recurrence was almost identical in both groups (31% for right-sided colon cancers and 30.9% for left-sided colon cancers). Age over 61 years was a predictive factor of poor prognosis in recurrence-free survival (hazard ratio = 3.245; p = 0.023). Conclusions We identified factors that can influence perioperative outcomes and prognosis in patients with right-sided colon cancer compared to those with left-sided colon cancer. Our findings suggest that age and lymph node involvement along with other factors play a role in the overall survival and recurrence outcomes of these patients. Further research is necessary to explore these differences and develop personalized treatment plans for patients with colon cancer.

Selection of appropriate reference creatinine estimate for acute kidney injury diagnosis in patients with severe trauma.

In patients with severe trauma, the diagnosis of acute kidney injury (AKI) is important because it is a predictive factor for poor prognosis and can affect patient care. The diagnosis and staging of AKI are based on change in serum creatinine (SCr) levels from baseline. However, baseline creatinine levels in patients with traumatic injuries are often unknown, making the diagnosis of AKI in trauma patients difficult. This study aimed to enhance the accuracy of AKI diagnosis in trauma patients by presenting an appropriate reference creatinine estimate (RCE). We reviewed adult patients with severe trauma requiring intensive care unit admission between 2015 and 2019 (n=3,228) at a single regional trauma center in South Korea. AKI was diagnosed based on the current guideline published by the Kidney Disease: Improving Global Outcomes organization. AKI was determined using the following RCEs: estimated SCr75-modification of diet in renal disease (MDRD), trauma MDRD (TMDRD), admission creatinine level, and first-day creatinine nadir. We assessed inclusivity, prognostic ability, and incrementality using the different RCEs. The incidence of AKI varied from 15% to 46% according to the RCE used. The receiver operating characteristic curve of TMDRD used to predict mortality and the need for renal replacement therapy (RRT) had the highest value and was statistically significant (0.797, P<0.001; 0.890, P=0.002, respectively). In addition, the use of TMDRD resulted in a mortality prognostic ability and the need for RRT was incremental with AKI stage. In this study, TMDRD was feasible as a RCE, resulting in optimal post-traumatic AKI diagnosis and prognosis.

Treatment of advanced trigger finger by ulnar superficialis slip resection: Long-term outcome and predictive factors for poor prognosis

The aim of this study was to evaluate the outcome of ulnar superficialis slip resection and to determine predictive factors for poor prognosis in patients with advanced trigger finger. Over a 5-year-period, 55 patients (58 fingers) were included. After surgery, two groups were identified: group 1, with complete extension or <10° extension deficit in the proximal interphalangeal (PIP) joint (n = 27 fingers/27 patients); and group 2, with ≥10° residual PIP extension deficit (n = 31 fingers/28 patients). Factors associated with PIP extension deficit were assessed on logistic regression. There was a median extension gain of 20° (range, 10−30°) after surgery. The difference between pre- and post-operative extension deficits was significant (p < 0.001). There was no significant inter-group difference in DASH score (p > 0.9). Two predictive factors were found: >12 months’ preoperative symptom duration (OR = 1.02; p = 0.045), and lack of self-rehabilitation (OR = 20; p < 0.001). Ulnar superficialis slip resection was effective in advanced trigger finger. Hand surgeons should operate early on these patients, and encourage self-rehabilitation. Level of evidence4

High expression of caspase-8 as a predictive factor of poor prognosis in patients with esophageal cancer.

Esophageal carcinoma (ESCA) is considered to be one of the most common gastrointestinal cancers. Caspase-8 (CASP8) is a key protein of cross-talk signaling in a variety of cancers. However, the role of CASP8 expression in the prognosis of patients with ESCA has remained unexplored. Hence, it is needed to explore the clinical significance of CASP8 expression in ESCA. The expression and prognosis of CASP8 were investigated in ESCA using the UALCAN, GEDS, TIMER, and OncoLnc databases. The CASP8 genetic variations in ESCA were assessed using the cBioPortal database. The correlation between CASP8 expression and tumor immune invasion and immune cell surface indicators was examined using the TIMER and TISIDTISIDB datasets. Meanwhile, the abundance of the immunological cells in the tumor and healthy tissues was assessed by the CIBERSORT method. Next, information on the co-expressed genes of the differentially expressed genes (DEGs) in ESCA-tumor and ESCA-healthy tissues was obtained using the cBioPortal, UALCAN, and Coexpedia databases. Subsequently, the PPI network was constructed and the GO and KEGG pathways were analyzed using the SIRING database. Finally, CASP8 mRNA and protein expression in the ESCA tissues and matched adjacent healthy tissues were analyzed using qRT-PCR, immune-blotting, and immunohistochemistry. Additionally, the relationship between clinicopathological features and CASP8 expression was assessed. ESCA tissues had higher levels of CASP8 mRNA and protein expression compared to healthy tissues. patients with an elevated level of CASP8 expression had poor overall survival (OS). CASP8 expression was significantly correlated with the degree of differentiation (P = 0.004) and lymph node metastasis (P = 0.044). There were diverse patterns of association between immunological cell surface biomarkers and CASP8 expression. ESCA showed significant levels of CASP8 expression which may serve as a prognostic biomarker correlated to immune infiltrates in ESCA.

C-Reactive Protein (CRP): A poor prognostic biomarker in COVID-19.

The COVID-19 pandemic continues to be rampant with considerable morbidity and mortality worldwide since its emergence in December 2019. Several studies have focused on identifying different predictive factors of poor prognosis, including biological markers, such as C Reactive Protein among others. The objective of our work was to determine whether the CRP levels on admission to the intensive care unit are predictive of an unfavorable evolution of patients with COVID-19 through the experience of the Anesthesia and Intensive Care Unit of the University Hospital of Oujda and to compare our results with those reported in the literature. We conducted a retrospective, monocentric, descriptive and analytical study in the Department of Anesthesia and Intensive Care of the Mohammed VI University Hospital of Oujda, Morocco, between March 2020 and October 2021, including all critically ill patients admitted to the department during this period and meeting the inclusion criteria. The baseline admission CRP value was arbitrarily set at 100mg/d, thus conditioning the division of our patients into two groups (group 1: CRP < 100mg/L, group 2: CRP ≥ 100mg/L). Among our 1035 included patients, 291 patients with had a CRP<100mlg/L (group 1) and 744 presented a CRP level equal or superior to 100mg/L (group 2). Lung parenchymal involvement was more severe or even critical (CT involvement > 75%) in group 2 (60.8%) compared to group 1 (39.2%). In group 2, 79.8% of patients were mechanically ventilated, compared to 20.2% of patients in group 1. Finally, the mortality rate in patients with a CRP ≥ 100mg/l was 77.4%, compared with 22.6% for patients with a CRP < 100mg/l. These findings are all statistically highly significant (p<0.001). Given the high contagiousness of the virus and the emergence of several variants, the management of the COVID-19 pandemic has focused more on prevention through vaccination against the virus, but also on an early identification of patients likely to evolve unfavorably for a personalized management.

Serum high-sensitive C-reactive protein is a simple indicator for all-cause among individuals with MAFLD.

High-sensitive C-reactive protein (hs-CRP) is one of the diagnostic components for metabolic (-dysfunction) associated fatty liver disease (MAFLD). This study aimed to explore the relationship between hs-CRP level and 25-year mortality in patients with MAFLD. The study data were from the Third National Health and Nutrition Examination Survey 1988-1994. All participants were followed up until December 2015 and the outcome of each participant was ascertained from National Death Index records. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence interval (CI) of all-cause mortality, cardiovascular-related mortality, and malignancy-related mortality. A total of 4,145 participants with MAFLD were included in final analysis. The median follow-up period was 22.3years (interquartile range 16.9-24.2). There were 1,610 (38.8%) all-cause deaths. The leading cause of death was malignant neoplasms (365/1,610, 22.7%), followed by cardiovascular diseases (342/1,610, 21.2%). Of the 4,145 patients with MAFLD, 1,293 (31.2%) had an hs-CRP level greater than 0.5mg/dl. Those with hs-CRP > 0.5mg/dl were older, more likely to be female and had greater derangements of metabolic profiles than those with lower hs-CRP. The results of Cox regression analysis showed that hs-CRP ≥ 0.5mg/dl was an independent risk factor for all-cause mortality (HR = 1.394, 95% CI 1.253-1.551), cardiovascular mortality (HR = 1.497, 95% CI 1.190-1.885) and malignant neoplasms related mortality (HR = 1.290, 95% CI 1.030-1.615) after adjusting for risk factors. This study confirms that hs-CRP is an independent predictive factor of poor prognosis in patients with MAFLD.

Increased ANXA5 expression in stomach adenocarcinoma infers a poor prognosis and high level of immune infiltration.

The prognostic role of annexin A5 (ANXA5) in stomach adenocarcinoma (STAD) has not been studied, and its relationship with immune infiltration is still unclear. This investigation aimed at exploring the role of ANXA5 in STAD using an integrated bioinformatics analysis. The expression of ANXA5 in STAD and the correlations between the effect of ANXA5 and survival of STAD patients were investigated using database. The clusterProfiler package in R software was used to perform enrichment analysis on the top 100 co-expressed genes of ANXA5 from the COXPRESdb online database. Correlations between ANXA5 and immune cell infiltrates were analyzed using the TIMER database. In STAD, ANXA5 expression was significantly upregulated and increased ANXA5 expression was significantly correlated with poor overall survival (P< 0.05). In multivariate analysis, upregulated ANXA5 expression was an independent predictive factors of poor prognosis (P< 0.05). The co-expressed genes were involved in extracellular matrix (ECM)-related processes. In STAD, ANXA5 expression was significantly correlated with various infiltrating immune cells (P< 0.05). Together with our findings, ANXA5 could serve as a potential biomarker to assess prognosis and immune infiltration level in STAD.

Reticulocalbin3: A Ca2+ homeostasis regulator that promotes esophageal squamous cell carcinoma progression and cisplatin resistance.

Esophageal squamous cell carcinoma (ESCC) is one of the most prevalent cancers worldwide. There is a critical need to identify new mechanisms that contribute to ESCC progression. Reticulocalbin3 (RCN3) is mainly located in the endoplasmic reticulum and Ca2+‐binding protein containing EF‐hands. The function of RCN3 in tumor progression has not been clarified. We observed that the expression level of RCN3 was higher in ESCC tissues than in paired normal tissues. Overexpression of RCN3 was positively associated with tumor size, lymph node metastasis, TNM stage, lymphatic vessel infiltration, and poor outcome in patients with ESCC. Increased malignant phenotypes were observed in RCN3 overexpressing ESCC cells, whereas the opposite effects were achieved in RCN3‐silenced cells. Reticulocalbin3 promoted the expression of MMP‐2 and MMP‐9 by regulating the inositol 1,4,5‐trisphosphate receptor 1 (IP3R1)–Ca2+–calcium/calmodulin‐dependent protein kinase II–c‐Jun signaling pathway. Reticulocalbin3 induced cisplatin resistance by regulating IP3R1/Ca2+ to maintain intracellular Ca2+ homeostasis and reduced reactive oxygen species in ESCC cells. Finally, the expression of RCN3 was regulated by hypoxia inducible factor‐1α. Collectively, these data strongly support that RCN3 regulates Ca2+ homeostasis by targeting IP3R1 to promote the progression and platinum resistance of ESCC. Our studies suggest that RCN3 could serve as predictive factor of poor prognosis and potential therapeutic target for ESCC patients.

NCAPH is a prognostic biomarker and associated with immune infiltrates in lung adenocarcinoma

Non-SMC condensin I complex subunit H (NCAPH) plays a regulatory role in various cancers. However, its role in prognosis and immune infiltrates in lung adenocarcinoma (LUAD) remains unclear. This study examined the expression of NCAPH in tumor tissues and its association with immune infiltrates and prognostic roles in LUAD patients. Patients characteristics were obtained from The Cancer Genome Atlas (TCGA). Integrated analysis of TCGA showed that NCAPH was overexpressed across cancers, including LUAD. NCAPH expression was verified by quantitative polymerase chain reaction and western blotting in 20 LUAD matched tissues. High NCAPH expression was significantly related to T, N, M, pathologic stage, primary therapy outcome and smoking status according to the Wilcoxon rank sum test. Cox and Kaplan–Meier analyses showed that the NCAPH-high group was associated with shorter OS. The PFI and DSS in the NCAPH-high group were significantly decreased. Multivariate analysis showed that NCAPH was an independent predictive factor for poor prognosis. Gene set enrichment analysis demonstrated that the G2/M checkpoint, ncRNA metabolic, memory B cells, KRAS, E2F targets and MIER1 process were significantly associated with NCAPH expression. Single-sample Gene Set Enrichment Analysis indicated that NCAPH expression was associated with levels of Th2 and mast cells. The impact of NCAPH on malignant phenotypes was evaluated by MTT, transwell, cell cycle and apoptosis assays in vitro. The malignant phenotype of LUAD cells was inhibited if NCAPH was knocked down. In conclusion, this research indicates that NCAPH could be a potential factor for predicting prognosis and a new biomarker in LUAD.

High Expression of C8orf76 Is an Independent Predictive Factor of Poor Prognosis in Patients with Breast Cancer.

C8orf76 is a nuclear protein-encoding gene highly expressed in gastric tumor tissues that contributes to poor overall survival (OS). However, its function in breast cancer is unknown. We used The Cancer Genome Atlas (TCGA) database to investigate the role of C8orf76 in breast cancer. We used logistic regression to estimate the relationship between C8orf76 and clinical-pathological features, followed by Kaplan-Meier and Cox regression analyses to assess the prognostic value of the gene regarding survival of patients with breast cancer from TCGA database. To explore the biological functions of C8orf76, gene ontology (GO), Kyoto Genome Encyclopedia (KEGG) enrichment analysis, and gene set enrichment analysis (GSEA) were used. We established a nomogram for high or low C8orf76 expression in breast cancer patients based on Cox multivariate analysis. Finally, we verified the proliferation-promoting effect of C8orf76 on breast cancer cells with CCK8 kit and further explored its role of apoptosis by flow cytometry. High C8orf76 expression was observed in breast cancer tissues and significantly correlated with clinical stage. Kaplan-Meier survival analysis showed that elevated C8orf76 expression was associated with poor OS. Among the highly expressed C8orf76 phenotypes, GO and KEGG analysis showed significant enrichment in aromatase activity and PPAR signaling pathway, whereas GSEA showed differential enrichment in receptor tyrosine signaling, PI3K/AKT signaling pathway, and some data sets in extracellular matrix and adhesion. Lower expression of C8orf76 leads to reduced proliferation, increased apoptosis, and downregulation of pAKT and Bcl-2 in breast cancer cells. High C8orf76 expression may be a valuable biomarker related to the diagnosis and prognosis of patients with breast cancer.

Relationship of prognostic factors in stomach cancer with Helicobacter pylori: A retrospective study

Background and study aims: The prognostic value of H. pylori, which infects more than half of the human population living in the world and plays a role in gastric cancer pathogenesis, is controversial. Our aim is to investigate the relationship between H. pylori and prognostic factors in gastric cancer. Patients and methods: The data of 110 patients (38 females and 72 males) that underwent surgeries due to gastric cancer between 2014 and 2017 were retrospectively analyzed. The relationships between survival (disease-free and overall) and factors such as p53, HER2/neu, Ki-67, neutrophil and platelet lymphocyte ratio (NLR / PLR), histopathological and demographic characteristics were examined. In addition, the results of H. pylori positive and negative groups were compared. Results: Sixty-one (55%) patients were H. pylori negative and 49 (45%) were positive. In multivariate analysis, TNM stage, lymph node capsule invasion and NLR were determined as independent prognostic factors in both disease-free and overall survival. Age&gt;62 and PLR&gt;14.3 were determined as independent predictive factors of poor prognosis in overall survival. In univariate analysis, tumor diameter of &gt;4.3 cm, lymphovascular and perineural invasion, and diffuse p53 expression were determined as predictive factors of poor prognosis in disease-free and overall survival. The effectiveness of these markers in prognosis was not different between H. pylori negative and positive groups. Conclusion: While age, tumor diameter, TNM stage, lymph node capsule invasion, perineural and lymphovascular invasion, diffuse p53, PLR, and NLR were determined as prognostic factors in gastric cancer, these factors were not affected by the presence of H. pylori.
