UNASSIGNED: Biliary stricture caused by malignant tumors is known as Malignant Biliary Stricture (MBS). MBS is challenging to differentiate clinically, and accurate diagnosis is crucial for patient prognosis and treatment. This study aims to identify the risk factors for malignancy in all patients diagnosed with biliary stricture by Endoscopic Retrograde Cholangiopancreatography (ERCP), and to develop an effective clinical predictive model to enhance diagnostic outcomes.
UNASSIGNED: Through a retrospective study, data from 398 patients diagnosed with biliary stricture using ERCP between January 2019 and January 2023 at two institutions: the First People\'s Hospital affiliated with Jiangsu University and the Second People\'s Hospital affiliated with Soochow University. The study began with a preliminary screening of risk factors using univariate regression. Lasso regression was then applied for feature selection. The dataset was divided into a training set and a validation set in an 8:2 ratio. We analyzed the selected features using seven machine learning algorithms. The best model was selected based on the Area Under the Receiver Operating Characteristic (ROC) Curve (AUROC) and other evaluation indicators. We further evaluated the model\'s accuracy using calibration curves and confusion matrices. Additionally, we used the SHAP method for interpretability and visualization of the model\'s predictions.
UNASSIGNED: RF model is the best model, achieved an AUROC of 0.988. Shap result indicate that age, stricture location, stricture length, carbohydrate antigen 199 (CA199), total bilirubin (TBil), alkaline phosphatase (ALP), (Direct Bilirubin) DBil/TBil, and CA199/C-Reactive Protein (CRP) were risk factors for MBS, and the CRP is a protective factor.
UNASSIGNED: The model\'s effectiveness and stability were confirmed, accurately identifying high-risk patients to guide clinical decisions and improve patient prognosis.

BACKGROUND: Surgery is currently the only effective treatment for retroperitoneal tumors that do not involve any specific organ. The use of robots for removing both benign and malignant retroperitoneal tumors is considered safe and feasible. However, there is insufficient evidence to determine whether robotic retroperitoneal tumor resection (RMBRs) is superior to open retroperitoneal malignant resection (OMBRs). This study compares the short-term outcomes of robotic excision of benign and malignant retroperitoneal tumors with open excision of the same-sized tumors.
METHODS: The study compared demographics and outcomes of patients who underwent robotic resection (n = 54) vs open resection (n = 54) of retroperitoneal tumors between March 2018 and December 2022. A 1:1 matching analysis was conducted to ensure a fair comparison.
RESULTS: The study found that RBMRs resulted in reduced operative time (OT), estimated blood loss (EBM), and postoperative hospital stay (PSH) when compared to OBMRs. Additionally, RBMRs reduced EBL, PHS, and OT for patients with malignant tumor involvement in major vessels. No significant differences were found in tumor size, blood transfusion rate, and morbidity rate between the RBMRs and OBMRs groups.
CONCLUSIONS: When comparing RMBRs to OMBRs, it was observed that RMBR was associated with lower (EBL), shorter postoperative hospital stays (PHS), and reduced operative time (OT) in a specific group of patients with both benign and malignant tumors.

To evaluate the incidence of malignancies in acromegaly and to identify risk factors for newly-diagnostic cancers, especially the excessive growth hormone (GH) and insulin-like growth factor-1 (IGF-1).
A retrospective cohort including 1738 consecutive hospitalized patients with acromegaly in a single referral center between 2012 and 2020 (mean follow-up 4.3 years). A gender- and age-matched case-control study (280 patients from the cohort) was performed for risk factor analysis.
One hundred thirteen malignancies (67 diagnosed after acromegaly) were observed. The overall newly-diagnostic cancer risk of acromegaly was higher than the general population (standardized incidence ratio (SIR) 2.81; 95% CI 2.18-3.57). The risk of thyroid cancer (n = 33, SIR 21.42; 95% CI 13.74-30.08) and colorectal cancer (n = 8, SIR 3.17; 95% CI 1.37-6.25) was elevated. In the overall cohort, IGF-1 (ULN: 1.27 vs. 0.94, p = 0.057), GH (1.30 vs. 1.00 ng/ml, p = 0.12), and disease-controlled rate (34.9% vs. 45.9%, p = 0.203) at the last visit did not reach significance between patients with and without post-diagnostic cancer. In the case-control study, GH (1.80 vs. 0.90 ng/ml, p = 0.018) and IGF-1 (ULN: 1.27 vs. 0.91, p = 0.003) at the last visit were higher in patients with post-diagnostic cancers, with a lower disease-controlled rate. Elder age was a risk factor for cancer. Other metabolic comorbidities and the size of pituitary tumors were similar.
The risk of malignancies, especially thyroid cancer, was increased in patients with acromegaly in our center. More cancer screening should be considered when managing acromegaly, especially in patients with higher posttreatment GH and IGF-1.

UNASSIGNED: To investigate the effects of endoscopic endonasal surgery (EES) on longitudinal quality of life (QoL) in patients with malignant tumors of the anterior skull base.
UNASSIGNED: Eligible patients prospectively completed the Anterior Skull Base Surgery Questionnaire (ASBQ) and the 22-item Sino-Nasal Outcome Test (SNOT-22) questionnaires in referring to 3 different periods throughout their treatment and recovery.
UNASSIGNED: Forty patients were included. The median volume coronal maximum length of the tumor was 3.6 cm (95% CI 2.7-4.1cm). Overall QoL significantly worsened at 1 month postoperatively but returned to baseline after 1 year. Unrelieved symptoms in specific domains prompted further evaluation of individual items. Transient worsening of taste (p=0.011) and olfaction (p=0.004) lasted for 1 month but gradually relieved within the first postoperative year, but vision consistently worsened over the course of the treatment (p=0.126). Age>50 years (p<0.001), comorbidities (p<0.001), tumor necrosis (p<0.001) and recurrence (p=0.001) were associated with worse preoperative QoL. Poor long-term QoL was noted in those undergoing adjuvant therapy (p=0.032). Overall ASBQ scores (p=0.024), subdomain scores in specific symptoms (p=0.016), and vision scores (p=0.009) were worse only in patients with the greater coronal maximum diameter at 1-month postoperatively. Greater coronal maximum diameter was related to worse preoperative subdomain scores regarding specific symptoms (p=0.030) and decreased postoperative long-term decreased vision scores (p=0.014).
UNASSIGNED: Long-term site-specific and sinonasal QoL eventually stabilized after EES. Greater coronal maximum diameter was significantly associated with worsened vision function. Temporarily worse olfactory, vision, and taste function may be tied to decreased short-term QoL.

BACKGROUND: Studies that address the changing characteristics of diseases are of great importance for preventing and controlling the occurrence and development of diseases and for improving health. However, studies of the epidemiological characteristics of noncommunicable diseases (NCDs) and malignant tumors (MTs) of the residents in Guiyang, China, are lacking.
OBJECTIVE: The aim of this study was to evaluate the prevalences of NCDs and MTs in residents of Guiyang, Guizhou Province, China, and analyze differences among ages, genders, and regions.
METHODS: A multistage stratified cluster sampling method was used. Based on the inclusion and exclusion criteria, 81,517 individuals were selected for the study. Of these, 77,381 (94.9%) participants completed the study. Structured questionnaires were used to collect information on demographic characteristics, NCDs, and MTs. The chi-square test (with 95% confidence intervals) was used to analyze differences in disease prevalence among genders, ages, and geographical regions.
RESULTS: The major chronic NCDs of Guiyang residents are obesity, hypertension, and diabetes. MTs in women are mostly breast cancer, cervical cancer, and endometrial cancer, whereas in men, MTs are mainly lung cancer, rectal cancer, and gastric cancer. The prevalences of hypertension and diabetes in women are higher than in men, but the prevalences of lung cancer and gastric cancer in men are higher than in women. The epidemiological characteristics of individuals in different life stages are dissimilar. In terms of regional distribution, the prevalences of the above diseases in the Baiyun and Yunyan districts of Guiyang are relatively high.
CONCLUSIONS: Several NCDs (obesity, hypertension, and diabetes) and MTs (women: breast cancer, cervical cancer, and endometrial cancer; men: lung cancer, rectal cancer, and gastric cancer) should be the focus for the prevention and control of chronic diseases in the future. In particular, the Baiyun and Yunyan districts of Guiyang are the important regions to emphasize.

UNASSIGNED: The purpose was to evaluate the effect of thermal ablation combined with activated functional killer (AFK) cells immunotherapy for patients with malignant tumors.
UNASSIGNED: A cohort of 10 patients with malignancies received thermal ablation combined with AFK cells immunotherapy. Progression-free survival (PFS), overall survival, laboratory test, and postoperative complications were assessed.
UNASSIGNED: The success rate of the combination therapy was 100% and no severe complications occurred. Five patients maintained in PFS (50%) during the follow-up. The median PFS was 11 months (range 3.5-16.75 months). The hemoglobin (P = 0.023), hematocrit (P = 0.034), and lymphocyte ratio (P = 0.023); neutrophil-to-lymphocyte ratio (P = 0.038), neutrophil ratio (P = 0.016), albumin (P = 0.006), and alkaline phosphatase (P = 0.029); CA-125 (P = 0.033); and D-dimer (P = 0.011) changed significant after ablation. Whereas the white blood cell count (P = 0.003), neutrophil count (P = 0.024), lymphocyte count (P =0.003), monocyte ratio (P = 0.008), and eosinophil ratio (P = 0.005) changed significantly after combination therapy. The lymphocytes (P = 0.001) in the surviving patients increased more significantly after treatment. After the combination therapy, the percentage of CD3 + cells (P = 0.016) and CD3+ CD8+ cells (P = 0.002) increased, while CD3-CD16+ CD56+ (P = 0.002) and CD4+/CD8+ (P = 0.016) decreased.
UNASSIGNED: Combination of thermal ablation and AFK cells immunotherapy is a safe and effective method for patients with malignancy. And adoptive immunotherapy with AFK cells may be helpful to prevent recurrence after thermal ablation in patients with advanced cancer.

Preclinical models are a core feature of translational research, and patient-derived xenograft (PDX) models have increasingly been used with such purpose. PDX involves the transplantation of fresh human tumor samples into immunodeficient mice to overcome immunologic rejection. It is a valuable tool for basic as well as preclinical research, contributing to the establishment of models to characterize the neoplasms to drug screening and to allow the identification of therapeutic targets. The use of these models is justified because they retain the histological and genomic features of the primary tumor. PDX models are well described for malignant neoplasms, for which the advantages are clear and include the development of drug treatments. The establishment of malignant tumors PDX is undeniably important from a medical perspective. However, few studies have used such models for benign neoplasms. The use of PDX for benign neoplasm studies can help to clarify the pathobiology of these diseases, as well as invasion and malignant transformation mechanisms, which from a biological perspective is equally important to the study of malignant tumors. Therefore, the aim of this study is to review the current methodology for PDX model generation and to cover its main applications, focusing on benign neoplasms.

Rectal cancer is a malignant tumor of the distal colon of epithelial origin. Every year, more than 30,000 (30 969 - 2018) new cases of Rectal cancer and 16,000 deaths (16 151) are registered in Russia. The index of reliability of accounting (the ratio of the number of dead to sick) is 0,52%. Rectal cancer refers to localities with an average mortality rate. In the North-Western Federal district, more than 3 thousand primary cases of Rectal cancer were registered (3285 - 2018). The state statistics of the Rectal cancer provides data on morbidity and mortality in three categories of ICD-10 together (C19-21). Detailed development of data not only separately for each category of ICD-10, but also for the fourth sign is possible only from the data bases of cancer registers. As of 01.01.2019, the Population cancer register of the North-Western Federal district created by us totaled more than 1 million cases of malignant tumors (1 067 661), including Rectal cancer - 50 745 cases, or 4,8%. The share of the Rectal cancer is close to the national average - 4,9%. The article presents a detailed structure of cancer pathology in Rectal cancer. The leading role of the 3 specified categories belongs to the rectal malignant tumors (C20) - 75,4%, 19,8% falls on the malignant tumors of the rectosigmoid department (C19) and only 4,7% on the C21 - malignant tumors of the anus and anal canal. For all these categories, the dynamics of the structure is presented, which proved to be quite stable.
Рак прямой кишки (РПК) — это злокачественная опухоль дистального отдела толстой кишки эпителиального происхождения. Ежегодно в России регистрируется более 30 тыс. (30 969 в 2018 г.) новых случаев РПК и 16 тыс. (16 151) случаев смерти. Индекс достоверности учета (отношение числа умерших к заболевшим) составляет 0,52%. РПК относится к локализациям со средним уровнем летальности. В Северо-Западном Федеральном округе зарегистрировано более 3 тыс. первичных случаев РПК (3 285 в 2018 г.). Государственная статистика РПК представляет данные о заболеваемости и смертности населения по трем рубрикам МКБ-10 вместе (С19–21). Детальная разработка данных не только отдельно по каждой рубрике МКБ-10, но и по четвертому знаку возможна только по материалам баз данных раковых регистров. Созданный нами Популяционный раковый регистр Северо-Западного Федерального округа насчитывал на 01.01.2019 г. более 1 млн (1 067 661) случаев злокачественных новообразований (ЗНО), в том числе РПК — 50 745 случаев, или 4,8%. Удельный вес РПК близок к среднероссийскому — 4,9%. В работе представлена детальная структура онкологической патологии по РПК. Ведущая роль из трех указанных рубрик принадлежит ЗНО прямой кишки (С20) — 75,4%; 19,8% приходится на ЗНО ректосигмоидного отдела (С19) и только 4,7% на С21 — ЗНО ануса и анального канала. По всем этим рубрикам представлена динамика структуры, которая оказалась достаточно устойчивой.

Malignant tumors of the eye and its adnexa (C69) are rare malignancies. To date state statistics in Russia (Form No. 7) have data only for estimating the incidence of the population. These data, at our proposal, were included in Form No. 7 only since 2011. In 2018 for the first time we were able to have data on the incidence of the population by age separately for men and women but only in Russia as a whole. The estimation of rates of a 1- and 5-year patient survival for this pathology is carried out only by us in the North-West Federal Region of Russia, where, in February 2019, we have formed the first Population-based Cancer Registry (PCR) in Russia at the Federal Region\'s level with a total database of more than 1 million cases. Previously similar work was conducted on the materials of the Population-based Cancer Registry of Saint-Petersburg. For the first time this work presents the features of data on changes in the structure of oncological pathology of the eye and its adnexa (C69) and estimations of a 5-year survival by age. Unfortunately the Office of the Federal State Statistics Service classifies the pathology of the eye (C69) as a group of «other malignant tumors» and does not publish mortality data. At the same time, using the PCR database, it must be borne in mind that index accuracy (the ratio of a number of deaths to a number of sick for the first time in life) according to malignant tumors of the eye (C69) is about 0,50% and is constantly decreasing.
Злокачественные новообразования глаза и его придаточного аппарата (С69) относятся к редким опухолям. До настоящего времени государственная статистика в России (ф. № 7) «Сведения о злокачественных новообразованиях» располагает данными только для расчета заболеваемости населения. Эти данные были включены в ф. № 7 по нашему предложению только с 2011 г. В 2018 г. мы впервые смогли располагать данными о заболеваемости населения по возрасту отдельно для мужчин и женщин, но только в целом по России. Такая возможность имеется и у каждого территориального ракового регистра. Расчет показателей одно- и пятилетней выживаемости больных по этой патологии осуществляется только нами по 10 административным территориям Северо-Западного федерального округа, где в феврале 2019 г. был нами сформирован первый в России Популяционный раковый регистр (ПРР) на уровне федерального округа с общим объемом базы данных более 1 млн наблюдений. Ранее аналогичные работы осуществлялись только на материалах ПРР Санкт-Петербурга. В настоящей работе впервые представлены особенности изменения структуры онкологической патологии глаза и его придаточного аппарата (С69) и расчеты пятилетней выживаемости по возрасту. К сожалению, Управление Федеральной службы государственной статистики относит патологию глаза (С69) к группе «прочие ЗНО» и не публикует данные о смертности. Вместе с тем, используя базу данных ПРР, нужно иметь в виду, что индекс достоверности учета (отношение числа умерших к числу впервые в жизни заболевших) по ЗНО глаза (С69) составляет около 0,50% и постоянно снижается, а достоверность учета повышается.
