Malignant tumors are among the most important causes of death worldwide. The pathogenesis of a malignant tumor is complex and has not been fully elucidated. Studies have shown that such pathogenesis is related to abnormal cell cycle progression. The expression levels of cyclins, cyclin-dependent kinases (CDKs), and CDK inhibitors as well as functions of the cell cycle checkpoints determine whether the cell cycle progression is smooth. Cell-cycle-targeting drugs have the advantages of high specificity, low toxicity, low side effects, and low drug resistance. Identifying drugs that target the cell cycle and applying them in clinical treatments are expected to promote chemotherapeutic developments against malignant tumors. This article aims to review drugs targeted against the cell cycle and their action mechanisms. [ABSTRACT FROM AUTHOR]

Purpose: Serum fibrinogen and albumin play important roles in systemic inflammation and are implicated in tumor progression. The fibrinogen-to-albumin ratio (FAR) has shown a prognostic impact in several malignancies. This study aims to assess the prognostic value of the pretherapeutic FAR in patients with adenocarcinoma of the gastroesophageal junction (AEG) who underwent upfront resection. Methods: Consecutive patients who underwent surgical resection at the Department of Surgery at the Medical University of Vienna between 1992 and 2014 were included into this study. Optimal cut-off values were determined with the receiver-operating characteristic (ROC) curve, uni- and multivariate analyzes were calculated by the Cox proportional hazard regression model for overall survival (OS). Results: Among 135 included patients, the majority were male (79.26%), with a mean age of 66.53 years. Elevated FAR correlated significantly (p = 0.002) with shorter OS in univariate analysis, also confirmed as independent prognostic factor (p = 0.005) in multivariable analysis. The ROC curve of FAR (AUC = 0.744) outperformed fibrinogen (AUC = 0.738) and albumin (AUC = 0.378) in predicting OS for AEG patients. Conclusion: The FAR serves as an independent prognostic factor for OS in patients undergoing primarily resection for AEG. Given its routine availability and ease of calculation, FAR could help in diagnosis and treatment selection for AEG patients. Further validation studies are warranted to confirm these findings conclusively. [ABSTRACT FROM AUTHOR]

Objective: This study aims to assess the effect of mindfulness intervention on negative emotions (anxiety and depression) and quality of life in malignant tumor patients. Methods: The databases, including CNKI, VIP, Wanfang, Chinese Biomedical Literature Database disc (CBMdisc), PubMed, Embase, Cochrane Library, and Web of Science (WoS), were searched from inception to January 2024. Randomized controlled trials examining the effects of mindfulness intervention on negative emotions and quality of life in malignant tumor patients were selected. Metaanalysis was conducted using RevMan 5.1. Results: A total of 11 studies involving 993 patients were included. Compared with usual care, mindfulness intervention effectively reduced anxiety [SMD = -0.81, 95% CI (-1.01, -0.60), p < 0.00001], depression [SMD = -0.86, 95% CI (-1.01, -0.70), p < 0.00001], and improved patients' quality of life [SMD = 0.64, 95% CI (0.50, 0.78), p < 0.00001]. Conclusion: Mindfulness intervention can effectively alleviate negative emotions such as anxiety and depression in malignant tumor patients and positively impact their quality of life.

Background: Patients with prostate adenocarcinoma undergoing regular endocrine therapy may maintain normal PSA levels during follow-up, yet still progress to the highly malignant and rare prostatic sarcomatoid carcinoma, which is seldom reported. This article presents two case studies of prostatic sarcomatoid carcinoma. To date, only a few publications have described prostatic sarcomatoid carcinoma, and the clinical, morphological, and molecular dimensions of prostate adenocarcinoma warrant further investigation. Case description: Patient A was admitted two years ago due to difficulty urinating, with a PSA level of 6.35 ng/ml. A prostate needle biopsy was performed, and the postoperative pathology diagnosed prostate adenocarcinoma with a Gleason score of 9 (5 + 4, grade group 5). Citing personal reasons, the patient declined a radical prostatectomy and instead received ongoing androgen deprivation therapy (ADT), comprising goserelin, abiraterone, and prednisone. During follow-up, regular PSA tests showed no abnormalities. One year ago, the patient was admitted again due to difficulty urinating and hematuria, choosing to address only the urethral obstruction. Transurethral resection of the prostate was performed, and the postoperative pathology diagnosed sarcomatoid carcinoma of the prostate. Patient B was admitted three years ago due to difficulty urinating accompanied by hematuria. A prostate MRI and a whole-body radionuclide bone scan suggested prostate cancer with bone metastasis. Prostate needle biopsy confirmed the diagnosis. The patient was then regularly treated with androgen deprivation therapy, using goserelin. Throughout the follow-up period, the PSA levels consistently remained within normal limits. One year ago, the patient was admitted due to rectal bleeding. It was speculated that the symptoms of rectal bleeding might have been caused by the prostate cancer invading the rectal wall. A prostate needle biopsy was performed, and the pathology diagnosed sarcomatoid carcinoma of the prostate. Conclusions: This case underscores the inadequacy of relying solely on PSA levels to monitor high-grade prostate adenocarcinoma during endocrine therapy, as patients may progress to highly malignant atypical variants despite normal PSA levels. We propose that for high-grade prostate cancer patients who are unable to undergo radical prostatectomy, regular and frequent MRI screenings or repeat biopsies should be integral during endocrine therapy and follow-up. Furthermore, a detailed review of the patient's treatment history and clinical data, including immunohistochemical findings, might offer deeper clinical insights into prostatic sarcomatoid carcinoma.

One main feature of a malignant tumor is its uncontrolled growth. In this paper, we propose a simple tumor-immune model to study the progressive characteristics of malignant and benign tumors, where the anti-tumor immunity can be described by the Michaelis–Menten function or the mass action law. The model includes only two state variables for the tumor cells and the effector cells representing the immune system. Three quantities with clear biological meanings are given to determine the asymptotic states of the tumor progression. Moreover, differences in asymptotic states between the two anti-tumor immunity descriptions are drawn. Differently from existing simple models, on the one hand, the model exhibits rich dynamical behaviors including super-critical and sub-critical Bogdanov–Takens bifurcations (consisting of Hopf bifurcation, saddle–node bifurcation, and homoclinic bifurcation) and saddle–node bifurcation of nonconstant periodic solutions (leading to the appearance of two periodic orbits) as the parameters vary; on the other hand, the malignant feature, dormancy, and immune escape of the tumor are revealed with numerical simulations. Furthermore, from the perspective of qualitative analysis and numerical simulations, how the obtained results can be applied to the treatment and control of tumors is illustrated.

Background: Osteoporosis with pathological fractures is a significant public health issue, contributing to morbidity, disability, diminished quality of life, and increased mortality. Understanding mortality trends related to this condition is crucial for developing effective interventions to reduce mortality and improve healthcare outcomes. This study aimed to analyze trends and causes of death associated with osteoporosis and pathological fractures in the United States using a multi-cause approach. Methods: Annual death and age-standardized mortality rate (ASMR) data from 1999 to 2020 were obtained from the Centers for Disease Control and Prevention (CDC) mortality database. Death certificates listing ICD-10 M82 (osteoporosis with pathological fracture) as an underlying or related cause of death were analyzed. Epidemiological data were analyzed, and the ASMR data were calculated for each year, and trends were assessed using the Cochran-Armitage trend test. Results: From 1999 to 2020, there were 40,441 deaths related to osteoporosis with pathological fractures in the United States, with a female-to-male ratio of 5.6:1. Among these, 12,820 deaths (31.7%) listed osteoporosis with pathological fractures as the underlying cause of death (UCD), yielding a female-to-male ASMR ratio of approximately 5.0-7.7:1. When classified as a non-UCD, the ASMR ratio was approximately 4.8–6.2:1. At the same time, we found that the total number of deaths classified as UCD and multiple causes of death (MCD), but the trend ratio of the two groups in different years did not change statistically significant (P > 0.05), and the ASMR of both groups showed a downward trend. The UCD-to-MCD ratio increased between 1999 and 2007, then decreased from 2007 to 2020. As MCD, the number of female deaths was more than that of male, and both showed a decreasing trend, but there was no statistical significance in the change of trend ratio in different years (P > 0.05). Deaths were predominantly concentrated in individuals over 75 years of age, with those over 84 years being the most affected. The number of deaths in different age groups showed a decreasing trend, and the change of trend ratio in different years was statistically significant (P < 0.05). White individuals had the highest number of deaths. The leading causes of death were heart diseases, chronic lower respiratory diseases, and alzheimer's disease. In addition, the number of deaths of patients with prostate cancer and breast cancer showed a significant downward trend, and the change of trend ratio between the two groups in different years was statistically significant (P < 0.05). Conclusions: Although mortality from osteoporosis with pathological fractures is decreasing, anti-osteoporosis therapy remains essential for elderly patients. Healthcare providers should remain vigilant for potential complications, including malignant neoplasms, and ensure timely diagnosis and treatment to further reduce mortality in this population.

The purpose of this study was to investigate the risk factors for delayed chemotherapy–induced vomiting (DCIV) in pediatric oncology patients. We collected data on pediatric patients from a tertiary care pediatric hospital in an Asian urban center. We analyzed the risk factors for DCIV in patients by univariate analysis and logistic regression. Patients were grouped according to age by the Youden index, and differences in clinical features between the high-risk and low-risk groups were calculated. In the univariate analysis, the number of chemotherapy days, pH, and blood glucose levels were significantly associated with DCIV. In the logistic regression analysis, patient age was an independent risk factor (odds ratio [OR] = 1.013, 95% confidence interval [CI] = 1.005-1.021, P =.002). Children in the high-risk group had a higher grade of vomiting (P <.05). Age is an important risk factor for DCIV in pediatric patients, with older children tending to experience more frequent and more severe vomiting. [ABSTRACT FROM AUTHOR]

MicroRNAs (miRNA) is a class of non-coding single-stranded RNAs with length of about 19-25 nucleotides, which can completely or incompletely bind to the 3'ntranslated region (3'UTR) of the tar- get gene, inhibit the translation of messenger RNAs or promote its degradation, and exert post-transcriptional regulatory effects. At present, it has been found that the expression of miR-324-5p is abnormal in a variety of malignant tumors, and miR-324-5p regulates the proliferation, invasion, metastasis and apoptosis of cancer cells by acting on different target genes in different tumors, showing either oncogenic or pro-oncogenic effects. This article reviews the important biological functions and related mechanisms of miR-324-5p in malignant tumors, aiming to provide new ideas for the development of malignant tumor-related markers and effective therapeutic targets.

Objective To investigate and analyze the nutritional risk and nutritional treatment status of malignant tumor patients in a secondary hospital in Chongqing mountainous area under the background of rural revitalization. Methods A total of 2 986 malignant tumor patients admitted to the hospital from July 2021 to July 2023 were selected as the study subjects. The clinical information such as general data, incidence of nutritional risk, types and methods of nutritional therapy were collected retrospectively, and the rationality of clinical nutritional treatment was judged, Results Among the 2 986 patients, 2 516 cases were identified with nutritional risk, resulting in an overall incidence rate of 84.8%. Among those at nutritional risk, 732 patients received nutritional therapy, accounting for 29.1% (732/2516). Specifically, 186 patients received enteral nutrition (EN) therapy (the EN group, 25.4% of 732), 403 received parenteral nutrition (PN) therapy (the PN group.55.1% of 732), and 143 received combined enteral and parenteral nutrition (the combined therapy group, 19.5% of 732). The incidence rates of nutritional risk and malnutrition were significantly lower in middle-aged and young patients [80.75%(910/1127) and 39.57% (446/1 127) respectively compared to elderly patients [87.24%(1606/1 841) and 57.41% (1057/1 841) respectively, with all differences being statistically significant (P<0.05). After nutritional therapy, nutritional indicators including body mass index, serum total protein, hemoglobin, and plasma albumin levels significantly improved in the 732 treated patients. Patients in the combined therapy group showed better outcomes in all nutritional indicators compared to those in the EN and PN groups, and the EN group showed better outcomes compared to the PN group, with all differences being statistically significant (P<0.05). Conclusion The nutritional risk of malignant tumor patients in a secondary hospital in Chongqing mountainous area is high, the incidence of malnutrition is high, and the status of nutritional treatment is not optimistic.

Tumor organoids, derived from tumor tissues, are three-dimensional structures created in vitro to mimic in vivo tumor growth. They possess comparable genetic lineage and pathological characteristics to the original tumor, making them a promising research platform for studying tumor biology. In recent years, significant advancements in techniques such as microfluidics, cell coculture and vascularization have greatly promoted the development of Organ-on-a-Chip (OoC) and expanded the applications of tumor organoid models in both basic and clinical translational research. These advancements include leveraging tumor organoid models to investigate drug resistance mechanisms, perform drug screening, and facilitate clinical trials of precisional therapy. However, current organoid models still face several limitations, including the instability of cell culture quality, low cost-effectiveness, and the inability to accurately replicate the complex tumor microenvironment and spatial structures. Further research is needed to overcome these technical bottlenecks and improve the application of organoid models in cancer research, thereby further enhancing the depth of tumor research. This review summarized the development history and latest progress of tumor organoids. In terms of the latest applications of tumor organoids, this article reviewed disease modeling, research and development of innovative tumor drugs, and their application in personalized treatment. It also summarized the recent clinical researches of organoids; In addition, this review provided a detailed introduction to the technological progress of tumor organoids, including the development of novel culture devices, simulation of tumor microenvironment, and induction of angiogenesis. In summary, this review explored the latest developments, defects and future directions in the research of tumor organoids, aiming to provide reference for the study of tumor organoids.

Background: To investigate whether protein induced by vitamin K antagonist-II (PIVKA-II) combined with alpha-fetoprotein (AFP) can improve the diagnostic and differential diagnostic accuracy of childhood hepatic tumors. Methods: A multi-center prospective observational study was performed at nine regional institutions around China. Children with hepatic mass (Group T) were divided into hepatoblastoma group (Group THB) and hemangioendothelioma group (Group THE), children with extrahepatic abdominal mass (Group C). Peripheral blood was collected from each patient prior to surgery or chemotherapy. The area under the curve (AUROC) was used to evaluate the diagnostic efficiency of PIVKA-II and the combined tumor markers with AFP. Results: The mean levels of PIVKA-II and AFP were both significantly higher in Group T than Group C (p = 0.001, p < 0.001), in Group THB than Group THE (p = 0.018, p = 0.013) and in advanced HB than non-advanced HB (p = 0.001, p = 0.021). For the diagnosis of childhood hepatic tumors, AUROC of PIVKA-II (cut-off value 32.6 mAU/mL) and AFP (cut-off value 120 ng/mL) was 0.867 and 0.857. The differential diagnostic value of PIVKA-II and AFP in hepatoblastoma from hemangioendothelioma was further assessed, AUROC of PIVKA-II (cut-off value 47.1mAU/mL) and AFP (cut-off value 560 ng/mL) was 0.876 and 0.743. The combined markers showed higher AUROC (0.891, 0.895 respectively) than PIVKA-II or AFP alone. Conclusions: The serum level of PIVKA-II was significantly higher in children with hepatic tumors, especially those with malignant tumors. The combination of PIVKA-II with AFP further increased the diagnostic performance. Trial registration: Clinical Trials, NCT03645655.

ObjectiveTo understand the death status of major chronic diseases among the registered residents in Xuhui District, Shanghai from 2007 to 2021, and to analyze the probability and trend of premature death, so as to provide an evidence for the policy-making of disease control and prevention.MethodsBased on the data from the death registration system of the registered residents in Xuhui District, Shanghai from 2007 to 2021, the mortality rate of major chronic diseases, life expectancy without cause of death, potential years of life lost (PYLL), average years of life lost (AYLL), and premature death rate were calculated. Joinpoint 4.8 software was used to calculate the annual percentage change (APC) of premature death rate and its trend.ResultsIn 2021, the mortality rate and standardized mortality rate of four major chronic diseases, namely cardiovascular and cerebrovascular diseases, malignant tumors, diabetes mellitus and chronic lower respiratory diseases among the registered residents in Xuhui District, Shanghai was 767.75/100 000 and 234.69/100 000, respectively, accounting for 85.63% of the total causes of death among the residents in Xuhui District, Shanghai. The PYLL, AYLL and PYLL rate were 10 710.00 person-years, 1.49 years per person, and 11.43‰, respectively. Life expectancy increased by 14.91 years after removing the four major chronic diseases. From 2007 to 2021, the premature death rate of chronic diseases among the registered residents in Xuhui District decreased from 9.38% to 7.91% (APC=-1.09%,P

Primary metastatic prostate cancer to the orbit is exceedingly rare. Benign lesions, including meningioma, have demonstrated PSMA expression and can be visualized using PSMA-based PET tracers. We report the findings of 18F-PSMA-1007 PET/CT in a 76-year-old man with progressive confusion and long-standing blindness of the left eye. PET/CT scan revealed increased uptake of PSMA in the orbital and temporal region, and other sites throughout the body. Histopathological examination after biopsy of the left orbit showed adenocarcinoma of the prostate. This case substantiates the diverse clinical and radiological presentations of metastatic prostate cancer and underscores the diagnostic significance of targeted biopsy.

METHODS: Adipose mesenchymal stem cells and adipose mesenchymal stem cell-derived exosomes were extracted and identified. In vitro model of radiationinduced oral mucositis was induced by radiating oral mucosal epithelial cells with 3 Gy X-ray. Adipose mesenchymal stem cells or adipose mesenchymal stem cell-derived exosomes were pretreated for 48 hours before modeling. The proliferation capacity of oral mucosal epithelial cells was detected by EdU assay and clonal formation assay. A mouse model of radiation-induced oral mucositis was constructed through 3 Gy X-ray radiation. Adipose mesenchymal stem cells and adipose mesenchymal stem cell-derived exosomes were injected into the tail vein of radiation-induced oral mucositis mice. Hematoxylin-eosin staining and immunohistochemistry were used to evaluate the inflammatory changes of oral mucosal epithelial tissue. RESULTS AND CONCLUSION: (1) Compared with the control group, both adipose mesenchymal stem cells and adipose mesenchymal stem cell-derived exosomes promoted the formation of oral epithelial cell clones and increased the positive rate of EdU in oral epithelial cells. (2) Both adipose mesenchymal stem cells and adipose mesenchymal stem cell-derived exosomes alleviated the inflammation of oral mucosal epithelium of irradiated mice; CD45 positive cells decreased and PCNA positive cells increased in oral mucosal epithelium. It is concluded that adipose mesenchymal stem cell-derived exosomes promote the proliferation of oral mucosal epithelial cells and release oral mucosal inflammation in mice with radiation-induced oral mucositis.

The oncolytic virus (OV) therapy utilizes natural or genetically modified viruses to specifically target and infect tumor cells, leading to the destruction of cancer cells by the replication of the virus itself. This process also alters the immune microenvironment of the tumor transforming “cold” into “hot”, and mobilizes the body's immune system. The effectiveness of oncolytic viruses in anti-tumor therapy depends on factors such as the type of virus, host immunity and route of administration. Immunotherapy aims to activate the immune system and exert anti-tumor effect by relying on autoimmune function. With the development of genetic engineering technology, oncolytic viruses can enhance the anti-tumor effect through gene editing reconstruction, and can be used to treat tumors alone or in combination with other therapies. In view of the limited efficacy of single application of oncolytic virus therapy in clinic, the combination of oncolytic virus therapy and immunotherapy provides a new strategy for tumor treatment. This review started from the types of oncolytic viruses approved in the clinic, characteristics and its anti-tumor mechanisms. At the same time, it combed through the treatment of oncolytic viruses in the clinical trial stage, summarized the combined treatment strategies of oncolytic viruses, especially the combination of tumor immunotherapy represented by immune checkpoint inhibitor (ICI) and adoptive cell therapy (ACT), and put forward some thoughts and prospects of oncolytic viruses in the anti-tumor treatment in combination with the experience accumulated by the project team in the research of oncolytic viruses.

ObjectiveTo evaluate the risk of cardiac adverse events in patients with malignant tumors after chemotherapy by using a combination of acoustic cardiography and blood indices. MethodsA total of 171 patients with malignant tumor who received chemotherapy were included. They were divided into cardiac adverse event group and non-cardiac adverse event group in accordance with whether cardiac adverse events occurred after chemotherapy. The general data, blood indices before chemotherapy, and acoustic cardiography-related indices in the early stage (1-3 cycles) of chemotherapy of the two groups were analyzed. The possible influencing factors were determined by binary logistic regression analysis, and the nomogram was drawn. The receiver operating characteristic (ROC) curve was used to evaluate the prediction ability of the nomogram. ResultsCardiac adverse events occurred in 44 of 171 patients with malignant tumors after chemotherapy, and the incidence of cardiac adverse events was 25.73%. Binary logistic regression results showed that age, red blood cell distribution width (RDW) before chemotherapy, activated partial thromboplastin time (APTT), and electromechanical activation time (EMAT) at the early stage of chemotherapy were independent predictors of cardiac adverse events in chemotherapy patients. The area under the ROC curve of the nomogram was 0.768 (95%CI: 0.693-0.843, P

Objective·To analyze the epidemiological characteristics of risk factors for cardiovascular diseases and malignant tumors based on the Shanghai community elderly cohort.Methods·The study subjects were selected from the Shanghai community elderly cohort established from February to August 2019, with a total of 17 948 people. The study subjects were divided into 4 groups according to self-reported presence or absence of tumors and/or cardiovascular diseases during the baseline survey: tumor-free and non-cardiovascular disease group, single cardiovascular disease group, single tumor group and tumor cardiovascular disease co-occurrence group. The differences among the four groups of subjects were collected and compared in terms of demographic characteristics and physiological indicators, daily living habits (smoking, drinking tea, drinking coffee, drinking carbonated drink, drinking alcohol, sedentary time, physical activity level and sleep quality), past medical history, psychological status (depression and anxiety) and dietary compliance.Results·Among the study subjects, 60.1% of tumor patients were complicated with cardiovascular diseases. The differences among the four groups of subjects in age, gender, educational level, pre-retirement occupation, waist circumference, hip circumference and body mass index were statistically significant (all P

Abstract Background Ischemic stroke (IS) and malignant tumor (MT) have high morbidity and mortality rates worldwide, and several associations exist between them. This study aimed to determine the effect of MT on hospital mortality in patients with IS. Methods Based on their MT status, participants with IS in the Medical Information Mart for Intensive Care IV (MIMIC-IV) were divided into two groups. The primary outcome was in-hospital all causes mortality. Kaplan-Meier survival analysis was performed to evaluate the intergroup in-hospital mortality, and three Cox regression models were used to determine the association between MT and in-hospital mortality. Results A total of 1605 participants (749 males and 856 females) were included in the study. The mean age was 72.030 ± 15.463 years. Of these, 257 (16%) patients died in the hospital. Kaplan-Meier analysis showed that the MT group had a significantly lower possibility of in-hospital survival than the non-MT group. In the unadjusted model, in-hospital mortality among MT patients had a higher odds ratio (OR) of 1.905 (95% CI, 1.320–2.748; P

Ubiquitination is a crucial post-translational modification process that can degrade proteins within cells and plays a vital role in maintaining protein homeostasis and abundance. Deubiquitinating enzymes (DUBs) are important proteases in the ubiquitin system. They reverse the ubiquitination process by cleaving protein chains and recycling ubiquitin molecules to regulate protein stability. Abnormal deubiquitinating enzyme activity is related to the occurrence and development of many malignant tumors. JOSD2, a DUB, is a member of the Machado-Joseph disease protein domain protease (MJD) family and characterized by a single highly conserved catalytic Josephin domain. Increasing studies have revealed a connection between JOSD2 and malignant tumors. This article elaborates on the current research status of DUBs, particularly JOSD2, in malignant tumors. Results suggest that JOSD2 is a potential target for the treatment of malignant tumors.

Chimeric antigen receptor-T cell therapy, a groundbreaking cancer treatment, has achieved remarkable success against hematologic malignancies. However, CAR-T monotherapy faces challenges in certain cases, including treatment tolerance and relapse rates. To overcome these challenges, researchers are investigating combining CAR-T cells with other treatments to enhance therapeutic efficacy. Therefore, this review aims to investigate the progress of research in combining CAR-T cells for hematologic malignancies. It covers the basic principles and clinical applications of CAR-T cell therapy, detailing combinations with chemotherapy, immune checkpoint inhibitors, targeted drugs, radiotherapy, hematopoietic stem cell transplantation, and other treatments. These combinations synergistically enhance the antitumor effects of CAR-T cells and comprehensively target tumors through different mechanisms, improving patient response and survival rates.

Objective: To investigate the effects of motivational interview education on psychological status, compliance behavior and quality of life in patients with malignant tumors combined with diabetes mellitus. Methods: This is a retrospective study. Eighty patients with malignant tumors combined with diabetes mellitus admitted at The Fourth Hospital of Hebei Medical University from January 2021 to June 2022 were included as subjects and divided into observation group and control group according to the intervention measures. Patients in the control group were given routine health education intervention, while those in the observation group were given motivational interviewing intervention on the basis of the control group. We compared the prognosis, cognitive function, quality of life, relief of cancer pain before intervention and three months after the intervention of the two groups were compared. Results: At three months after the intervention, the total remission rate of cancer pain in the observation group was higher than that in the control group (p<0.05), while the levels of FBG and 2hPG in the observation group were significantly lower than those in the control group (p<0.05). Self-Rating Anxiety Scale (SAS) and Self-rating depression scale (SDS) scores decreased in both groups three months after the intervention, with the level of reduction in the observation group being higher than that in the control group (p<0.05). The overall compliance was higher in the observation group than in the control group (p<0.05). Conclusion: Motivational interviewing leads to alleviate negative emotions, improve the psychological status, enhance compliance behavior and improve quality of life in patients with malignant tumors combined with diabetes mellitus.

• The study develops a prediction model specifically tailored to accurately assess the malnutrition status of elderly hospitalized cancer patients. • It demonstrates that the XGBoost model is exceptionally effective in identifying malnutrition, providing oncologists with a valuable tool for managing nutritional risks and supporting elderly cancer patients. • The findings underscore the significance of incorporating machine learning techniques into nutritional assessment strategies for elderly cancer patients. Malnutrition is prevalent among elderly cancer patients. This study aims to develop a predictive model for malnutrition in hospitalized elderly cancer patients. Data from January 2022 to January 2023 on cancer patients aged 60+ were collected, involving 22 variables. Key variables were identified using the LASSO (Least Absolute Shrinkage and Selection Operator) method, and nine machine learning models were tested. SHAP was used to interpret the XGBoost model. Malnutrition prevalence was assessed. Among 450 participants, 46.4 % were malnourished. Key predictors identified were ADL (Activities of Daily Living), ALB (Albumin), BMI (Body Mass Index) and age. XGBoost had the highest AUC of 0.945, accuracy of 0.872, and sensitivity of 0.968. Higher ADL and age increased malnutrition risk, while lower ALB and BMI reduced it. The XGBoost model is highly effective in detecting malnutrition in elderly cancer patients, enabling early and rapid nutritional assessments. [ABSTRACT FROM AUTHOR]

Introduction. In Poland, interventions of emergency medical teams in patients with malignant tumors represent a small percentage of all interventions. Patients with malignant tumors constitute a diverse group in which the patient may manifest a wide spectrum of symptoms and complaints affecting different systems and organs. The aim of this study was to retrospectively analyze emergency medical team interventions in patients with malignant tumors. Material and methods. 1174 emergency medical services forms from emergency medical team interventions in patients with malignant tumors from April 2019 to December 2022 in the Kujawsko-Pomorskie voivodship in Poland were analyzed. Results. In the study group 52% were male. The mean age of the subjects was 66 years (SD = 12.31). The most common symptoms in patients were pathological respiratory murmurs (11.7%), psychomotor disorders (11.3%), hypoxemia (10.3%), dyspnea (9.5%) and pain (5.8%). 40.5% of patients were transported to hospital. A total of 7496 emergency medical procedures were performed, most of them involving physical examination and assessment of the patient's condition. The pharmacotherapy administered most commonly involved analgesics (30.9%), electrolytes (24%) and glucocorticosteroids (20.1%). Seventy-four patients (6.3%) died during EMT intervention. Conclusions. Emergency medical teams most often provide assistance to patients with malignant tumors of the respiratory and thoracic organs and organs of the digestive system. The majority of oncology patients do not require hospital treatment, but only outpatient care. Therefore, there is a need to regulate and optimize the actions taken by emergency medical teams when intervening in patients with malignant tumors. [ABSTRACT FROM AUTHOR]

Laryngeal squamous cell carcinoma (LSCC) is one of the most aggressive cancers that affect the head and neck region. Recent researches have confirmed that long non-coding RNAs (lncRNAs) present an emerging role in diversiform diseases including cancers. Prostate cancer-associated ncRNA transcript 6 (PCAT6) is an oncogene in lung cancer, cervical cancer, colon cancer and gastric cancer, but its role in LSCC is still unknown. In the current study, we attempted to figure out the role of PCAT6 in LSCC. RT-qPCR was to analyze PCAT6 expression in LSCC cells. Functional assays were to uncover the role of PCAT6 in LSCC. Mechanism assays were to explore the regulatory mechanism behind PCAT6 in LSCC. PCAT6 exhibited higher expression in LSCC cells and PCAT6 strengthened cell proliferation and inhibited cell apoptosis. Furthermore, lncRNA PCAT6 modulated notch receptor 3 expression and activated NOTCH signaling pathway via serving as a sponge for miR-4731-5p. Taken together, lncRNA PCAT6 was identified as an oncogene in LSCC, which revealed that PCAT6 might be used as potential therapeutic target for LSCC. [ABSTRACT FROM AUTHOR]

Objective To analyze the incidence and mortality of malignant tumors attributed to HPV infection in Sichuan region from 2018 to 2022. Methods From January 2018 to December 2022, the population, tumor incidence rate and mortality in Sichuan were collected, and the population attributable fraction (PAF) attributable to HPV infection was calculated by age and sex. Results The population attributable proportions of HPV infection among residents in Sichuan region from 2018 to 2022 for the incidence and mortality of common malignant tumors were 65. 0% and 59. 2% respectively. The attribution of HPV (PAF) to the incidence of malignant tumors in the oropharynx, oral cavity, and throat of males was higher than that of females 二 78. 904, P < 0. 001). The attributable HPV (PAF) of cervical, vulva, oral, and laryngeal malignant tumors in urban populations was higher than that in rural populations (χ² = 119. 03, P < 0. 001). In addition, there was a gender difference (P < 0. 05) in the relationship between the incidence of tumors attributed to HPV infection and age, indicating that males had earlier onset ages for various tumors. The attribution of HPV (PAF) to death in male oropharyngeal, oral, and laryngeal malignant tumors was higher than that in females (χ² = 110. 578, P < 0. 001). The mortality attributable HPV (PAF) of cervical, anal, oropharyngeal, oral, and laryngeal malignant tumors in urban populations was higher than that in rural populations(χ² = 66. 285, P < 0. 001). In addition, there was a gender difference (P <0. 05) in the relationship between tumor mortality attributed to HPV infection and age, with males dying earlier for oral and oropharyngeal malignancies, and females dying earlier for anal malignancies. Conclusion From 2018 to 2022, the incidence and death of tumors attributed to HPV infection in Sichuan region are more, and the incidence and death show an increasing trend, among which timely screening of cervical cancer is the key to reduce the incidence and death of HPV tumors.

Background: Soft tissue tumors (STTs) are benign or malignant superficial neoplasms arising from soft tissues throughout the body with versatile pathological types. Although Ultrasonography (US) is one of the most common imaging tools to diagnose malignant STTs, it still has several drawbacks in STT diagnosis that need improving. Objectives: The study aims to establish this deep learning (DL) driven Artificial intelligence (AI) system for predicting malignant STTs based on US images and clinical indexes of the patients. Methods: We retrospectively enrolled 271 malignant and 462 benign masses to build the AI system using 5-fold validation. A prospective dataset of 44 malignant masses and 101 benign masses was used to validate the accuracy of system. A multi-data fusion convolutional neural network, named ultrasound clinical soft tissue tumor net (UC-STTNet), was developed to combine gray scale and color Doppler US images and clinic features for malignant STTs diagnosis. Six radiologists (R1-R6) with three experience levels were invited for reader study. Results: The AI system achieved an area under receiver operating curve (AUC) value of 0.89 in the retrospective dataset. The diagnostic performance of the AI system was higher than that of one of the senior radiologists (AUC of AI vs R2: 0.89 vs. 0.84, p=0.022) and all of the intermediate and junior radiologists (AUC of AI vs R3, R4, R5, R6: 0.89 vs 0.75, 0.81, 0.80, 0.63; p <0.01). The AI system also achieved an AUC of 0.85 in the prospective dataset. With the assistance of the system, the diagnostic performances and inter-observer agreement of the radiologists was improved (AUC of R3, R5, R6: 0.75 to 0.83, 0.80 to 0.85, 0.63 to 0.69; p<0.01). Conclusion: The AI system could be a useful tool in diagnosing malignant STTs, and could also help radiologists improve diagnostic performance. [ABSTRACT FROM AUTHOR]

This study examines a three-dimensional (3D) thermal-electric model comprising a hepatic tissue, four small radiofrequency probes, and a big blood vessel. The finite element method (FEM) is used to determine the distribution of tissue temperature during radiofrequency (RF) hepatic tumor ablation. The aim is to pinpoint the specific heated cells targeted for elimination and safeguard the neighboring healthy tissues. This will help in the effective and safe treatment of liver tumors. The mathematical model is simulated over 0 to 1000 seconds with a 22 to 50-volt voltage range. The iterative scheme shows good convergence. The temperature fields are analyzed and displayed graphically using iso-surfaces at 50°C with different time intervals. The graph depicts the heat distribution at the tip of one electrode arm over time. It demonstrates the temperature changes at a fixed voltage and various voltages during tumor ablation. Based on the RF simulation results, the temperature rises as tumor ablation and electric voltage duration increase. The tumor cells are effectively destroyed at around 50°C using 22 volts over a 480-second heating period. This model could be a valuable tool for physicians to safely and efficiently treat tumors without harming healthy tissues. [ABSTRACT FROM AUTHOR]

Purpose: Tumors of the foot and ankle account for approximately 3%~5% of all musculoskeletal tumors, and accurate diagnosis is often delayed due to their rare prevalence. Therefore, the authors aimed to analyze the incidence, treatment methods, and prognostic factors of foot and ankle tumors treated at the authors' hospital. Materials and Methods: A retrospective single-center study examined 342 patients treated for foot and ankle tumors at the authors' hospital from January 2011 to February 2022. Data were collected from the electronic medical records (EMR) and picture archiving and communication systems (PACS). The information analyzed included gender, age, follow-up period, diagnosis, tumor occurrence and recurrence, treatment, and clinical outcomes. Results: Most cases (93.3%) were benign, but 6.7% were malignant. The main treatment for malignant tumors was surgical resection (91.3%). Approximately 53.1% of benign tumors and 91.3% of malignant tumors were treated with surgery, and two of the malignant tumors that did not undergo surgery had metastatic cancer. After surgery, 8.2% of benign lesions and 19.0% of malignant lesions recurred, and 9.5% of the patients with malignant tumors died after surgery. Conclusion: Most foot and ankle tumors are benign tumors, and the prognosis is not poor if treated properly, but most malignant tumors often require amputation. In some cases, however, amputation can be avoided with a combination of chemotherapy and radiation therapy. [ABSTRACT FROM AUTHOR]

Objective To evaluate the risk of cardiac adverse events in patients with malignant tumors after chemotherapy by using a combination of acoustic cardiography and blood indices. Methods A total of 171 patients with malignant tumor who received chemotherapy were included. They were divided into cardiac adverse event group and non-cardiac adverse event group in accordance with whether cardiac adverse events occurred after chemotherapy. The general data, blood indices before chemotherapy, and acoustic cardiography-related indices in the early stage (1-3 cycles) of chemotherapy of the two groups were analyzed. The possible influencing factors were determined by binary logistic regression analysis, and the nomogram was drawn. The receiver operating characteristic (ROC) curve was used to evaluate the prediction ability of the nomogram. Results Cardiac adverse events occurred in 44 of 171 patients with malignant tumors after chemotherapy, and the incidence of cardiac adverse events was 25.73%. Binary logistic regression results showed that age, red blood cell distribution width (RDW) before chemotherapy, activated partial throm- boplastin time (APTT), and electromechanical activation time (EMAT) at the early stage of chemother- apy were independent predictors of cardiac adverse events in chemotherapy patients. The area under the ROC curve of the nomogram was 0.768 (95%CI: 0.693-0.843, P<0.001). Conclusion A nomogram based on age, pre-chemotherapy RDW, APTT, and EMAT at the early stage of chemotherapy is useful for early assessment of the risk of cardiac adverse events in chemotherapy patients.

Background: Ischemic stroke (IS) and malignant tumor (MT) have high morbidity and mortality rates worldwide, and several associations exist between them. This study aimed to determine the effect of MT on hospital mortality in patients with IS. Methods: Based on their MT status, participants with IS in the Medical Information Mart for Intensive Care IV (MIMIC-IV) were divided into two groups. The primary outcome was in-hospital all causes mortality. Kaplan-Meier survival analysis was performed to evaluate the intergroup in-hospital mortality, and three Cox regression models were used to determine the association between MT and in-hospital mortality. Results: A total of 1605 participants (749 males and 856 females) were included in the study. The mean age was 72.030 ± 15.463 years. Of these, 257 (16%) patients died in the hospital. Kaplan-Meier analysis showed that the MT group had a significantly lower possibility of in-hospital survival than the non-MT group. In the unadjusted model, in-hospital mortality among MT patients had a higher odds ratio (OR) of 1.905 (95% CI, 1.320–2.748; P < 0.001) than the non-MT group. After adjusting for basic information, vital signs, and laboratory data, MT was also associated with increased in-hospital mortality (OR = 1.844, 95% CI: 1.255–2.708; P = 0.002). Conclusions: Among the patients with IS, the risk of all causes in-hospital mortality was higher for MT than for patients non-MT. This finding can assist clinicians in more accurately assessing prognosis and making informed treatment decisions. [ABSTRACT FROM AUTHOR]

Circular RNAs (circRNAs) are a new type of endogenous non-coding RNA formed by a covalent closed loop. CircRNAs are characterized by specificity, universality, conservation, and stability. They are abundant in eukaryotic cells and have biological regulatory roles at various transcriptional and post-transcriptional levels. The upregulation of circPRKCI has been observed in a variety of tumors and is directly related to the clinicopathological characteristics of tumors and prognosis. More importantly, circPRKCI can participate in the tumorigenesis, progression, recurrence, and metastasis of various tumors through many functional mechanisms, including the activation of signaling pathways, such as the phosphatidylinositol-3-kinase (PI3K)/AKT pathway, and sponging of many microRNAs (miRNAs). This review summarizes the progress achieved in understanding the biological functions of circRNA PRKCI in various tumors. The goal is to inform the discovery of more functional mechanisms and new anticancer molecular targets. [ABSTRACT FROM AUTHOR]

Ubiquitination is a crucial post-translational modification process that can degrade proteins within cells and plays a vital role in maintaining protein homeostasis and abundance. Deubiquitinating enzymes (DUBs) are important proteases in the ubiquitin system. They reverse the ubiquitination process by cleaving protein chains and recycling ubiquitin molecules to regulate protein stability. Abnormal deubiquitinating enzyme activity is related to the occurrence and development of many malignant tumors. JOSD2, a DUB, is a member of the Machado-Joseph disease protein domain protease (MJD) family and characterized by a single highly conserved catalytic Josephin domain. Increasing studies have revealed a connection between JOSD2 and malignant tumors. This article elaborates on the current research status of DUBs, particularly JOSD2, in malignant tumors. Results suggest that JOSD2 is a potential target for the treatment of malignant tumors. [ABSTRACT FROM AUTHOR]

Objective·To analyze the epidemiological characteristics of risk factors for cardiovascular diseases and malignant tumors based on the Shanghai community elderly cohort. Methods·The study subjects were selected from the Shanghai community elderly cohort established from February to August 2019, with a total of 17 948 people. The study subjects were divided into 4 groups according to self-reported presence or absence of tumors and/or cardiovascular diseases during the baseline survey: tumorfree and non-cardiovascular disease group, single cardiovascular disease group, single tumor group and tumor cardiovascular disease co-occurrence group. The differences among the four groups of subjects were collected and compared in terms of demographic characteristics and physiological indicators, daily living habits (smoking, drinking tea, drinking coffee, drinking carbonated drink, drinking alcohol, sedentary time, physical activity level and sleep quality), past medical history, psychological status (depression and anxiety) and dietary compliance. Results·Among the study subjects, 60.1% of tumor patients were complicated with cardiovascular diseases. The differences among the four groups of subjects in age, gender, educational level, pre-retirement occupation, waist circumference, hip circumference and body mass index were statistically significant (all P<0.05). Compared with the tumor-free and non-cardiovascular disease group, the single cardiovascular disease group, single tumor group and tumor cardiovascular disease cooccurrence group all exhibited lower proportions of smoking and high physical activity levels (all P<0.05), and higher proportion of sedentary time exceeding 4 h/d and poor sleep quality (all P<0.05); the proportion of subjects with past medical histories including hyperlipidemia, peripheral vascular disease, endocrine system disease, respiratory system disease, urinary system disease and digestive system disease of the single cardiovascular disease group and the tumor cardiovascular disease co-occurrence group was higher (all P<0.05), and the proportion of subjects with depression and anxiety was also higher (all P<0.05). Furthermore, compared with the tumor-free and non-cardiovascular disease group, the single cardiovascular disease group had lower compliance rates of poultry, fish, fruit and liquid milk (all P<0.05). Among the four groups, only the compliance rate of vegetable intake exceeded 50%, while the compliance rates of poultry, fish, fruit, liquid milk and tubers were all below 20%. Conclusion·In the elderly population of Shanghai communities, over half of malignant tumor patients are concomitant with cardiovascular diseases. Unhealthy daily habits are prevalent among those with cardiovascular diseases, tumors and tumor-cardiovascular disease co-occurrence. The intake of many foods in the elderly of the community do not reach the levels recommended by Chinese Dietary Guidelines. [ABSTRACT FROM AUTHOR]

Purpose: Despite its rich vascularity, metastasis (MTS) to the thyroid tissue is unusual, ranging from 1 to 3%. This entity is not usually considered as differential diagnosis and is not included in the upfront approach in patients with thyroid nodules. Once diagnosed, treatment is controversial. The aim of this study was to evaluate diagnosis, treatment, and outcome at the end of follow-up in patients with a diagnosis of MTS to the thyroid. Methods: A retrospective multicenter study was designed from 1985 to 2022; 29 patients with MTS to the thyroid gland were included in the analysis. Results: Clinical presentation included the presence of a nodular goiter (65.5%), compression symptoms (17.2%), diffuse goiter (10.3%), and suspicious lymph nodes in the neck (7%). Primary tumor sites were: kidney (44.8%), breast (24.1%), lung (13.8%), neuroendocrine system (6.9%), colon (3.4%), cervix (3.4%), and ovary (3.4%). In 18/23 patients, suspicious ultrasound criteria for malignancy were described. Preoperative diagnosis was made in 23/27 patients by FNA and confirmed in 18 cases by immunohistochemistry. Seventeen patients underwent surgery. At the end of the follow-up, 19 patients had died of oncological disease, and six were alive (2/6 disease-free with isolated intrathyroidal MTS). Conclusion: Renal carcinoma was the tumor that most frequently metastasized to the thyroid gland. Immunodiagnosis was a very useful tool for etiological confirmation. Patients with MTS to the thyroid gland as a unique site had a more favorable course compared to patients with multiple metastatic sites. Finally, outcomes and prognosis essentially depended on the biology of the primary tumor. [ABSTRACT FROM AUTHOR]

Aim: To investigate whether age at first sexual intercourse could lead to any changes in the risk of oral cavity cancer. Methods: A two-sample mendelian randomization was conducted using genetic variants associated with age at first sexual intercourse in UK biobank as instrumental variables. Summary data of Northern American from a previous genome-wide association study aimed at oral cavity cancer was served as outcome. Three analytical methods: inverse variance-weighted, mendelian randomization Egger, and weighted median were used to perform the analysis, among which inverse variance-weighted was set as the primary method. Robustness of the results was assessed through Cochran Q test, mendelian randomization Egger intercept tests, MR PRESSO, leave one out analysis and funnel plot. Results: The primary analysis provided substantial evidence of a positive causal relationship age at first sexual intercourse and the risk of oral cavity cancer (p = 0.0002), while a delayed age at first sexual intercourse would lead to a decreased risk of suffering oral cavity cancer (β = -1.013). The secondary outcomes confirmed the results (all β < 0) and all assessments supported the robustness, too (all p > 0.05). Conclusion: The study demonstrates that a delayed sexual debut would provide protection against OCC, thus education on delaying sexual intercourse should be recommended. [ABSTRACT FROM AUTHOR]

Patients with malignant tumors are prone to present hypercoagulability of blood and form thrombosis, and its pathogenesis is complex involving various factors from clinical and histopathological to genetic influences. Current studies on the potential mechanism of blood hypercoagulability in patients with malignant tumors focus on the following aspects but are not limited: (1) tumor cells release coagulant-promoting substances, (2) tumor cells interact with the fibrinolytic system, (3) tumor cell-mediated platelet activation, (4) tumor-associated complement activation, and (5) genetic factors and clinical factors. Especially, the pathogenesis of blood hypercoagulability is in-depth analyzed covering tumor cells' release of procoagulant substances, the interplay of cancer cells and fibrinolytic system, platelet activation mediated by cancer cells, cancer-associated complement activation, and the action of genetic and clinical factors. We review the pathogenesis of blood hypercoagulability in patients with malignant tumors, which will assist in the research and development of new drugs and providing theoretical support for the formulation of the best treatment plan for patients, to prolong the survival of patients.

The platelet human leucocyte antigen (HLA) gene bank contains the genetic information of HLA loci in a large number of blood donors. Currently, the most effective treatment for platelet transfusion refractoriness (PTR) is to evaluate the probability of antigenic mismatch by HLA genotyping of patients and to select HLA-matched donors in the gene bank through an information system. This case report describes the treatment of PTR in patients with malignant tumors using the platelet HLA gene bank digital matching technique. The analysis of individual cases will help guide transfusion strategies for such patients.

An uncommon entity in the class of malignant neuroectodermal nasal tumors is the olfactory neuroblastoma, which originates in the roof of the nasal cavity from the olfactory epithelium. It is often mistaken by clinicians for a nasal polyp because it presents with indistinct features such as nasal obstruction and secondary sinus disease. Olfactory neuroblastoma has been observed to cause morbidity by distant metastasis, invasion through the cribriform plate, and secondary meningitis in most instances. It exhibits a range of biologic activities, from slow growth accompanied by long-term patient survival to a very aggressive malignancy with extensive metastases. We report the incidence of a rare case in which a patient, previously operated on and irradiated for squamous cell carcinoma of the maxilla, developed an olfactory neuroblastoma with orbital protrusion.
