Objective: To investigate the role of endoscopic ultrasonography (EUS) in the diagnosis and treatment of upper gastrointestinal bleeding of unknown origin in liver cirrhosis, focusing on patients with recurrent treatment of esophageal and gastric varices who failed to identify the bleeding site under direct endoscopy. Background: Esophagogastric variceal bleeding is one of the severe complications of decompensated liver cirrhosis, and serial endoscopic therapy can improve the long-term quality of life of patients. Most acute bleeding can be detected under direct endoscopy with thrombus or active bleeding, but there are still some patients with recurrent bleeding after repeated treatments, and it is difficult to find the bleeding site, especially in gastric variceal bleeding. Therefore, it is of great significance to identify the bleeding site. Patients and Methods: A total of 88 patients with liver cirrhosis bleeding diagnosed and treated under EUS were collected in this study, including 26 patients who failed to identify the bleeding site under direct endoscopy. EUS was used to scan the bleeding site, and EUS-guided treatment was performed. The characteristics of the bleeding site under direct endoscopy and EUS and the follow-up results after surgery were analyzed. Results: Among the 26 patients, 16 patients (16/26, 61.5%) showed red color signs of gastric fundus mucosa under direct endoscopy, 5 patients (5/26, 19.2%) showed punctate erosion, and the remaining 5 patients (5/26, 19.2%) showed no abnormal mucosal manifestations. All patients could find anechoic blood vessels under EUS, and blood flow signals could be detected within. Among them, 23 patients (23/26, 88.5%) chose EUS-guided treatment, and no rebleeding occurred after surgery. Another 3 patients (3/26, 11.5%) were given endoscopic variceal ligation due to small esophageal and gastric varices and inability to perform intravascular injection. The median follow-up time was 86 days. Adverse reactions included 5 cases of retrosternal pain (5/23, 21.7%), and 1 case of fever (1/23, 4.3%). Conclusion: EUS can detect submucosal varices in the gastric mucosa, and these bleeding sites may present as red color signs or punctate erosion under direct endoscopy.

Background To identify potential predictors of short-term survival among patients with lung cancer admitted to the intensive care unit (ICU). Methods A multicenter longitudinal observational study of patients with lung cancer was conducted between May 10, 2021 and July 10, 2021, at the ICUs of 37 cancer-specialty hospitals in China. This study included patients with a primary diagnosis of lung cancer who were admitted to the ICU for ≥24 h. Predictive factors for ICU outcomes, with 90-day survival as the major outcome, were explored using single and multivariate analyses. Results A total of 269 patients were included in the final analysis. The 90-day mortality rate following ICU care was 45.4%. Patients with 90-day mortality exhibited more severe conditions before admission, a higher number of ICU-related complications, and underwent more intense treatment than survivors. Notably, despite the low recorded incidence, acute kidney injury (AKI) was independently associated with ICU, in-hospital, and 90-day mortality outcomes in the multivariate analysis. Furthermore, condition severity at admission and ICU treatment choices, especially anti-infection regimen, were identified as potential correlators of a higher AKI risk. Conclusion AKI prediction and prevention may require prioritization in patients with lung cancer admitted in the ICU.

BACKGROUND:Colorectal cancer (CRC) is one of the most common cancers and CRC patients are among the most common intensive care unit (ICU) admitted cancer patients. However, their prognosis and evaluation methods are rarely studied. AIM:To determine the short-term mortality outcome and identify the potential prognostic factors of CRC cancer patients admitted to the ICU. METHODS:A multicenter cross-sectional study was performed from May 10, 2021 to July 10, 2021 at the ICU departments of 37 cancer specialized hospitals in China, and included patients aged ≥ 14 years with ICU duration ≥ 24 hours. Clinical records of patients with a primary CRC diagnosis were reviewed. Patients were separated into groups according to 90-day survival. Characteristics between groups were compared. Univariate and multivariate regression tests were used to analyze the correlated factors of ICU outcomes. Predictive values of disease severity scores were assessed using receiver operating characteristic curve analysis. RESULTS:In total, 189 CRC patients were included in the study. The 90-day mortality was 12.2%. Patients who died showed differences compared to patients who survived mostly in terms of disease severity and ICU complications. It appears that patients admitted to the ICU from a clinical ward due to emergencies may have a higher risk of mortality while surgical management was associated with better survival. In multivariate analysis, only chemotherapy, elective surgery and conventional oxygen therapy were identified as independently correlated with 90-day mortality. Sequential organ failure assessment and acute physiology and chronic health evaluation II scores had moderate accuracy in predicting short-term mortality. CONCLUSION:ICU admitted CRC patients appear to have low short-term mortality which requires further confirmation in prospective studies. The prognostic tools for these patients need further optimization.

BackgroundCentral venous catheters (CVCs) are widely used in critically ill patients, including cancer patients, but are associated with complications such as catheter-related bloodstream infections (CRBSIs). This study evaluates the effectiveness of polyhexamethylene biguanide (PHMB)-coated CVCs in reducing catheter-tip bacterial colonization in cancer patients undergoing abdominal surgery.MethodsA prospective, randomized, monocentric clinical trial was conducted at Peking University Cancer Hospital from March 2017 to April 2019. Surgical cancer patients requiring CVCs were randomized into two groups: a PHMB-coated CVC group (Certofix® protect) and a standard CVC group (Certofix®). The primary outcome was catheter tip bacterial colonization, and the secondary outcomes included catheter retention time and hospital length of stay.ResultsA total of 1,185 patients were included in the analysis. The incidence of catheter tip bacterial colonization was 2.5% in the PHMB-coated group and 4.2% in the standard CVC group (p = 0.10). Hospital length of stay was significantly shorter in the PHMB-coated group (p < 0.001). Subgroup analysis showed reduced bacterial colonization in male patients in the PHMB-coated group (p = 0.04).ConclusionPolyhexamethylene biguanide-coated CVCs did not significantly reduce catheter tip bacterial colonization in the overall population but showed a beneficial effect in male cancer patients undergoing abdominal surgery. In clinical practice, it is necessary to consider various factors when selecting the type of catheter.Clinical trial registrationNo. chiCTR-IPR-16010027.

Abstract Background The optimal duration and choice of anticoagulant for the treatment of Peripherally inserted central catheters (PICC)-related upper extremity deep vein thrombosis (UEDVT) in cancer patients are still undetermined. Objectives The aim of this study was to assess the efficacy and safety of rivaroxaban for the treatment of PICC-related UEDVT in cancer patients. Methods We conducted a retrospective cohort study including consecutive cancer patients for the management of acute symptomatic PICC-related UEDVT. The efficacy outcome of the study was the 180-day recurrence of any venous thromboembolism (VTE), while the safety outcome was the 180-day incidence of all bleeding events. The Kaplan‒Meier method was used to estimate the overall incidence. Hazard ratios (HRs) were obtained with a Cox proportional hazards model to estimate the risk of the outcome events. Results A total of 217 patients were included in the final analysis with a median age of 56 years old, 41.5% of whom had metastases. After the initial 3–5 days of nadroparin, patients received sequential anticoagulation, either with nadroparin (118 patients) or with rivaroxaban (99 patients). Four patients with recurrent VTE were observed (nadroparin, n = 2; rivaroxaban, n = 2). The 180-day cumulative VTE recurrence rates were 1.7% and 2.0% (p = 0.777) in patients receiving nadroparin and rivaroxaban, respectively. The overall bleeding rate at 180 days was 8.8%. Although no major bleeding events were observed, nineteen patients with clinically relevant nonmajor bleeding (CRNMB) were observed. The 180-day cumulative rate of CRNMB was 5.1% for nadroparin and 13.1% for rivaroxaban (HR = 3.303, 95% CI 1.149–9.497, p = 0.027). Conclusion Our study supported the efficacy of rivaroxaban for treating PICC-related UEDVT in cancer patients. However, data on anticoagulation therapy for PICC-related UEDVT presented with a low risk of VTE recurrence and a relatively high risk of CRNMB bleeding events. Considering the risk–benefit ratio, further well-designed trials are required to optimize the drug selection and duration for the treatment of PICC-related UEDVT in cancer patients.

To investigate the occurrence and 90-day mortality of cancer patients following unplanned admission to the intensive care unit (ICU), as well as to develop a risk prediction model for their 90-day prognosis. We prospectively analyzed data from cancer patients who were admitted to the ICU without prior planning within the past 7 days, specifically between May 12, 2021, and July 12, 2021. The patients were grouped based on their 90-day survival status, and the aim was to identify the risk factors influencing their survival status. A total of 1488 cases were included in the study, with an average age of 63.2 ± 12.4 years. The most common reason for ICU admission was sepsis (n = 940, 63.2%). During their ICU stay, 29.7% of patients required vasoactive drug support (n = 442), 39.8% needed invasive mechanical ventilation support (n = 592), and 82 patients (5.5%) received renal replacement therapy. We conducted a multivariate COX proportional hazards model analysis, which revealed that BMI and a history of hypertension were protective factors. On the other hand, antitumor treatment within the 3 months prior to admission, transfer from the emergency department, general ward, or external hospital, high APACHE score, diagnosis of shock and respiratory failure, receiving invasive ventilation, and experiencing acute kidney injury (AKI) were identified as risk factors for poor prognosis within 90 days after ICU admission. The average length of stay in the ICU was 4 days, while the hospital stay duration was 18 days. A total of 415 patients died within 90 days after ICU admission, resulting in a mortality rate of 27.9%. We selected 8 indicators to construct the predictive model, which demonstrated good discrimination and calibration. The prognosis of cancer patients who are unplanned transferred to the ICU is generally poor. Assessing the risk factors and developing a risk prediction model for these patients can play a significant role in evaluating their prognosis.

BACKGROUND AND OBJECTIVES:The aim of this study was to analyze risk factors for failure of subclavian vein catheterization.METHODS:A retrospective analysis of 1562 patients who underwent subclavian vein puncture performed by the same experienced operator at Peking University Cancer Hospital from January 1, 2016 to January 1, 2019 was conducted. The success or failure of subclavian vein catheterization was registered in all cases. Various patient characteristics, including age, gender, body mass index (BMI), preoperative hemoglobin, preoperative hematocrit, preoperative mean corpuscular hemoglobin concentration (MCHC), preoperative albumin, preoperative serum creatinine, puncture needles from different manufacturers and previous history of subclavian vein catheterization were assessed via univariate and multivariate analyses.RESULTS:For the included patients, landmark-guided subclavian vein puncture was successful in 1476 cases and unsuccessful in 86 cases (success rate of 94.5%). Successful subclavian vein catheterization was achieved via right and left subclavian vein puncture in 1392 and 84 cases, respectively. In univariate analyses, age and preoperative hemoglobin were associated with failure of subclavian vein catheterization. In a multivariate analysis, aged more than 60 years was a risk factor while the central venous access with Certofix® was associated with an increased rate of success (p-values of 0.001 and 0.015, respectively).CONCLUSIONS:This study has demonstrated that patient aged more than 60 years was a risk factor for failure of subclavian vein catheterization while the central venous access with Certofix® was associated with an increased rate of success.

BackgroundThe purpose of this study was to clarify the incidence, risk factors, and clinical outcomes of septic acute kidney injury (AKI) in cancer patients with sepsis admitted to the intensive care unit (ICU).MethodsA total of 356 cancer patients admitted to the ICU due to sepsis from January 2016 to October 2021 were analyzed retrospectively. According to the incidence of septic AKI, all patients were divided into the non-AKI group (n = 279) and the AKI group (n = 77). The clinical data after ICU admission were compared between the above two groups, and the risk factors and the clinical outcomes of septic AKI in the ICU were identified.ResultsThe incidence of septic AKI in all patients was 21.6% (77/356). LASSO regression and logistic regression all showed that lactate, sequential organ failure assessment (SOFA) score and septic shock were closely related to the occurrence of septic AKI. In terms of clinical outcomes after ICU admission, the rate of mechanical ventilation (MV) and continuous renal replacement therapy (CRRT), MV time, hospitalization time and 28-day mortality in the ICU were significantly higher in the septic AKI group than in the non-septic AKI group. Among the three subgroups of septic AKI (AKI combined with septic shock, septic cardiac dysfunction or acute respiratory failure), the mortality of patients in the subgroup of AKI combined with septic shock was significantly higher than others. CRRT has no significant effect on the short-term outcome of these patients.ConclusionLactate level, SOFA score and septic shock were closely related to the occurrence of septic AKI in the ICU. The clinical outcomes within 28 days after ICU admission of cancer patients with septic AKI were worse than those without septic AKI. The short-term outcome was worse in patients with septic AKI complicated with septic shock. CRRT does not have any significant effect on the short-term prognosis of cancer patients with septic AKI in the ICU.

Abstract Background Venous thromboembolism (VTE) is a threat to the prognosis of tumor patients, especially for critically ill patients. No uniform standard model of VTE risk for critically ill patients with tumors was formatted by now. We thus analyzed risk factors of VTE from the perspectives of patient, tumor, and treatment and assessed the predictive value of the ICU-VTE score, which consisted of six independent risk factors (central venous catheterization, 5 points; immobilization ≥ 4 days, 4 points; prior VTE, 4 points; mechanical ventilation, 2 points; lowest hemoglobin during hospitalization ≥ 90 g/L, 2 points; and baseline platelet count > 250,000/μL, 1 points). Methods We evaluated the data of tumor patients admitted to the intensive care unit of the Peking University Cancer Hospital between November 2011 and January 2022; 560 cases who received VTE-related screening during hospitalization were chosen for this retrospective study. Results The inhospital VTE occurrence rate in our cohort was 55.7% (312/560), with a median interval from ICU admission to VTE diagnosis of 8.0 days. After the multivariate logistic regression analysis, several factors were proved to be significantly associated with inhospital VTE: age ≥ 65 years, high tumor grade (G3–4), medical diseases, fresh frozen plasma transfusion, and anticoagulant prophylaxis. The medium-high risk group according to the ICU-VTE score was positively correlated with VTE when compared with the low-risk group (9–18 points vs. 0–8 points; OR, 3.13; 95% CI, 2.01–4.85, P < 0.001). The AUC of the ICU-VTE scores according to the ROC curve was 0.714 (95% CI, 0.67–0.75, P < 0.001). Conclusions The ICU-VTE score, as well as tumor grade, might assist in the assessment of inhospital VTE risk for critically ill patients with tumors. The predictive accuracy might be improved when combining two of them; further follow-up researches are needed to confirm it.

BACKGROUND:There were few studies on the prognosis of tumor patients with sepsis after gastrointestinal surgery and there was no relevant nomogram for predicting the prognosis of these patients.AIM:To establish a nomogram for predicting the prognosis of tumor patients with sepsis after gastrointestinal surgery in the intensive care unit (ICU).METHODS:A total of 303 septic patients after gastrointestinal tumor surgery admitted to the ICU at Peking University Cancer Hospital from January 1, 2013 to December 31, 2020 were analysed retrospectively. The model for predicting the prognosis of septic patients was established by the R software package.RESULTS:The most common infection site of sepsis after gastrointestinal surgery in the ICU was abdominal infection. The 90-d all-cause mortality rate was 10.2% in our study group. In multiple analyses, we found that there were statistically significant differences in tumor type, septic shock, the number of lymphocytes after ICU admission, serum creatinine and total operation times among tumor patients with sepsis after gastrointestinal surgery (P < 0.05). These five variables could be used to establish a nomogram for predicting the prognosis of these septic patients. The nomogram was verified, and the initial C-index was 0.861. After 1000 internal validations of the model, the C-index was 0.876, and the discrimination was good. The correction curve indicated that the actual value was in good agreement with the predicted value.CONCLUSION:The nomogram based on these five factors (tumor type, septic shock, number of lymphocytes, serum creatinine, and total operation times) could accurately predict the prognosis of tumor patients with sepsis after gastrointestinal surgery.

Persistent left superior vena cava (PLSVC) is a rare congenital anomaly. PLSVC can be associated with clinically significant atrial septal defect (ASD) or ventricular septal defect (VSD). It is usually asymptomatic and accidentally detected during invasive procedures or imaging examinations. However, whether central venous access device (CVAD) can be placed and used in patients with PLSVC is controversial. A total of six patients were diagnosed with PLSVC and confirmed by chest CT among 3391 cancer patients who underwent CVAD placement via intracavitary electrocardiogram (IC-EKG) at the Venous Access Center (VAC) from May 2019 to December 2020. The CVADs (peripherally inserted central catheter in four patients and Ports in two patients) of these six patients were left in PLSVC. We analyzed changes in the P-wave in the IC-EKG during CVAD placement and the characteristics of the body surface electrocardiogram in these patients and discussed the catheter tip position in PLSVC. All six patients showed negative P-waves in lead II via IC-EKG from the beginning of catheterization: four patients showed negative P-waves and two showed biphasic P-waves in the body surface electrocardiogram (lead III) before catheterization. CVAD function was normal and no obvious complications were observed during the treatment of these patients. The total retention time of CVADs was 1537 days. For patients with a negative P-wave in lead II via IC-EKG during catheterization, especially in those with a negative or biphasic P-wave in lead III of the body surface electrocardiogram, PLSVC should be considered. CVAD insertion in patients with type I PLSVC is safe under certain conditions, with the proper tip position in the middle to lower part of PLSVC.

PURPOSE:A peripherally inserted central catheter (PICC) is associated with venous thromboembolism (VTE) especially in patients suffering from cancer. We analyzed the incidence, risk factors, and patterns of PICC-related VTE in cancer patients.PATIENTS AND METHODS:Patients with cancer who underwent PICC placement were evaluated retrospectively. Routine, prospective ultrasound post-PICC placement was used for asymptomatic and symptomatic patients to identify VTE. Multivariable logistic regression models with odds ratios (ORs) were used to examine VTE risk factors.RESULTS:Of 2353 PICCs placed, 165 patients (7.01%) developed PICC-related VTE with a median thrombosis time of 12 days. After adjustment of multivariable analysis, patients with PICC-related VTE were more likely to have a ratio of PICC diameter:vein diameter >0.35 (adjusted OR, 1.689; 95% CI, 1.023-2.789) and high level of triglycerides (1.561; 1.096-2.223). The prevalence of A (adjusted OR, 1.680; 95% CI, 1.009-2.798), B (1.835; 1.137-2.961), and AB (3.275; 1.840-5.829) blood group was significantly higher than that of the O blood group in VTE patients. Venous recanalization was observed in 44.8% (74/165) patients after anticoagulation therapy, and more often in patients with combined deep VTE than in patients with isolated superficial VTE (OR, 17.942; 95% CI, 5.427-59.316). The recanalization time was 20±5 (range, 10-31) days.CONCLUSION:The non-O blood group, larger ratio of PICC diameter:vein diameter, and high level of triglycerides were significantly associated with PICC-related VTE. Almost half of cases of PICC-related deep VTE could be reversed by anticoagulation treatment.

Background To explore the clinical profiles and outcomes of patients with acute respiratory failure (ARF) after esophagectomy. Methods We retrospectively analyzed cases of patients who had been diagnosed with ARF after esophagectomy and compared survivors with non-survivors to explore the risks that may affect their outcomes. Results In total, 62 patients were admitted to the intensive care unit (ICU) with ARF after esophagectomy between January 1, 2010, and December 31, 2017. Of these patients, 69.4% needed mechanical ventilation, with an average time on the ventilator of 304 hours (304.33±374.37 hours). The average length of stay in the ICU and in the hospital were 14 days (14.48±17.64 days) and 50 days (50.15±37.28 days), respectively. Mortality in the ICU and 90 days after the operation was 6.5% and 16.1%, respectively. Compared with the survivors, the 90-day post-operative non-survivors had a poorer N stage in the TNM classification system. The causes of ARF included anastomotic leakage, pneumonia, vocal cord paralysis, sputum plugging, pulmonary embolism (PE), and acute respiratory distress syndrome (ARDS). ARF induced by different factors occurred at different times and had different outcomes. The three most common reasons for mortality in the ICU were ARDS (33.33%), anastomotic leakage (11.76%), and pneumonia (10%). The three most common reasons for mortality in the 90-day post-operative period were pneumonia (40%), anastomotic leakage (23.53%), and ARDS and acute exacerbations of chronic obstructive pulmonary disease (AECOPD) (33.33%). Conclusions Anastomotic leakage, pneumonia, ARDS, and AECOPD were the main causes of death in ARF patients after esophagectomy. We found that the N stage in the TNM classification system may affect 90-day post-operative mortality in these patients.

Chimeric antigen receptor T (CAR-T) cell has achieved excellent efficacy in hematological tumors, especially for lymphoma. Many products have been approved to market all over the world, and 2 products targeting CD19 have been approved to treat relapsed and refractory large B-cell lymphoma in China. The current experiences of using CAR-T cells come from previous clinical studies. How to use CAR-T cells in a standardized and rationalized way is still a challenge faced by our clinicians. Based on the CAR-T cell treatment experiences from Peking University Cancer Hospital and the latest research progresses in CAR-T in China and abroad, this article will elaborate on patient screening, peripheral blood mononuclear cell collection, bridging treatment, lymphocyte depletion chemotherapy, CAR-T cell infusion, the monitoring and treatment of adverse events after infusion, and long-term follow-up after infusion, in order to guide clinicians to better use CAR-T cell and to bring maximum benefits to patients.

BACKGROUND:There have been different reports on mortality of sepsis; however, few focus on the prognosis of patients with sepsis after surgery.AIM:To study the clinical features and prognostic predictors in patients with sepsis after gastrointestinal tumor surgery in intensive care unit (ICU).METHODS:We retrospectively screened patients who underwent gastrointestinal tumor surgery at Peking University Cancer Hospital from January 2015 to December 2019. Among them, 181 patients who were diagnosed with sepsis in ICU were included in our study. Survival was analysed by the Kaplan-Meier method. Univariate and multivariate adjusted analyses were performed to identify predictors of prognosis.RESULTS:The 90-d all-cause mortality rate was 11.1% in our study. Univariate analysis showed that body mass index (BMI), shock within 48 h after ICU admission, leukocyte count, lymphocyte to neutrophil ratio, international normalized ratio, creatinine, procalcitonin, lactic acid, oxygenation index, and sequential organ failure assessment (SOFA) score within 24 h after ICU admission might be all significantly associated with the prognosis of sepsis after gastrointestinal tumor surgery. In multiple analysis, we found that BMI ≤ 20 kg/m2, lactic acid after ICU admission, and SOFA score within 24 h after ICU admission might be independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery. Compared with SOFA score, SOFA score combined with BMI and lactic acid might have higher predictive ability (area under the receiver operating characteristic curve, 0.859; 95% confidence interval, 0.789-0.929).CONCLUSION:Lactic acid and SOFA score within 24 h after ICU admission are independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery. SOFA score combined with BMI and lactic acid might have good predictive value.

The major adverse cardiac events (MACE) are a major cause of perioperative death in patients of cancer combined with coronary heart disease. The risk factors of postoperative MACE in this specific population should be fully understood and analyzed to provide a theoretical basis for optimal management strategy. A total of 484 patients of cancer combined with coronary heart disease admitted to the intensive care unit of our hospital from January 2014 to December 2018 were retrospectively analyzed. The endpoint of observation was postoperative MACE. According to this endpoint, the patients were divided into the MACE group and the non-MACE group. The clinical baseline characteristics, additional examinations, and surgery-related indicators of the two groups were compared. Risk factors of MACE were analyzed by univariate and multivariate logistic analysis. A total of 56 patients (11.6%) were diagnosed with MACE during postoperative hospitalization in 484 patients. Univariate and multivariate logistic analyses were performed on the two groups: age ( P = 0.021), history of heart failure ( P = 0.033), history of angina within 6 months ( P = 0.001), cardiac ejection fraction ( P = 0.011), intraoperative hypoxia ( P = 0.021), and intraoperative hypotension ( P = 0.001) were Independent risk factors of MACE. The incidence of MACE was high in patients of cancer combined with coronary heart disease after non-cardiac surgery. Its independent risk factors include age, history of heart failure, history of angina within 6 months, cardiac ejection fraction, intraoperative hypoxia, and intraoperative hypotension.
