RESUMO
BACKGROUND: To provide data on the safety and efficacy of a combination chemotherapy regimen consisting of S-1, oxaliplatin, and irinotecan (SOXIRI) as a first-line therapy in unresectable pancreatic ductal adenocarcinoma (UPDA) patients. METHODS: Patients with UPDA and no prior treatment chemotherapy in the UPDA setting were enrolled. The primary endpoint was the objective response rate (ORR). Secondary endpoints were overall survival (OS), progression-free survival (PFS) and adverse events. Patients received 80 mg/m2 S-1 twice a day for 2 weeks in an alternate-day administration cycle, 85 mg/m2 oxaliplatin on Day 1, and 150 mg/m2 irinotecan on Day 1 of a 2-week cycle. RESULTS: In these 62 enrolled patients, the ORR was 27.4 %, median OS was 12.1 months, and median PFS was 6.5 months. Major grade 3 or 4 toxicity included neutropenia (22.3 %), leucopenia (16.1 %), nausea (9.7 %), vomiting (9.7 %), thrombocytopenia (6.5 %), anorexia (8.5 %), anemia (4.8 %), and diarrhea (1.6 %). No treatment-related deaths occurred. In addition, the analysis of 32 patients suffering pain revealed that the rate of pain relief was 34.4 %. CONCLUSION: SOXIRI might be a standard regimen with an acceptable toxicity profile and favorable efficacy for use as chemotherapy in patients with UPDA.

BACKGROUND: Rectal temperature (RT) is an important index of core temperature, which has guiding significance for the diagnosis and treatment of pet diseases. OBJECTIVES: Development and evaluation of an alternative method based on machine learning to determine the core temperatures of cats and dogs using surface temperatures. ANIMALS: 200 cats and 200 dogs treated between March 2022 and May 2022. METHODS: A group of cats and dogs were included in this study. The core temperatures and surface body temperatures were measured. Multiple machine learning methods were trained using a cross-validation approach and evaluated in one retrospective testing set and one prospective testing set. RESULTS: The machine learning models could achieve promising performance in predicting the core temperatures of cats and dogs using surface temperatures. The root mean square errors (RMSE) were 0.25 and 0.15 for cats and dogs in the retrospective testing set, and 0.15 and 0.14 in the prospective testing set. CONCLUSION: The machine learning model could accurately predict core temperatures for companion animals of cats and dogs using easily obtained body surface temperatures.

Although extensive research has been carried out on the epigenetic regulation of single RNA modifications in gastric cancer, little is known regarding the crosstalk of four major RNA adenosine modifications, namely, m6A, m1A, alternative polyadenylation and adenosine-to-inosine RNA editing. By analyzing 26 RNA modification "writers" in 1750 gastric cancer samples, we creatively constructed a scoring model called the "Writers" of the RNA Modification Score (WRM_Score), which was able to quantify the RNA modification subtypes of individual patients. In addition, we explored the relationship between WRM_Score and transcriptional and posttranscriptional regulation, tumor microenvironment, clinical features and molecular subtypes. We constructed an RNA modification scoring model including two different subgroups: WRM_Score_low and WRM_Score_high. The former was associated with survival benefit and good efficacy of immune checkpoint inhibitors (ICIs) due to gene repair and immune activation, while the latter was related to poor prognosis and bad efficacy of ICIs because of stromal activation and immunosuppression. The WRM score based on immune and molecular characteristics of the RNA modification pattern is a reliable predictor of the prognosis of gastric cancer and the therapeutic efficacy of immune checkpoint inhibitors in gastric cancer.

BACKGROUND: To date, the optimal recommended specific neoadjuvant regimens for resectable or borderline resectable pancreatic cancer (RPC or BRPC) remain an unanswered issue. METHODS: We systematically searched the electronic databases to identify randomized controlled trials (RCTs) comparing different neoadjuvant therapy strategies for RPC or BRPC. The primary outcome was overall survival (OS). Comprehensive analyses and evaluations were performed using the single-arm, paired, and network meta-analyses. RESULTS: Twelve RCTs involving 1279 patients with RPC or BRPC were enrolled. The paired meta-analysis showed that neoadjuvant therapy improved OS for both RPC (hazard ratio (HR) 0.69, 95% c.i. 0.54 to 0.87) and BRPC (HR 0.60, 0.42 to 0.86) compared with upfront surgery (UP-S). Neoadjuvant chemotherapy (NAC) also improved OS for both RPC (HR 0.63, 0.47 to 0.85) and BRPC (HR 0.44, 0.27 to 0.71), while neoadjuvant chemoradiotherapy (NACR) improved OS only for BRPC (HR 0.68, 0.52 to 0.89) and not for RPC (HR 0.79, 0.54 to 1.16). Network meta-analysis found that NAC was superior to NACR in OS for RPC/BRPC (HR 0.58, 0.37 to 0.90). Neoadjuvant chemotherapy based on modified fluorouracil/folinic acid/irinotecan/oxaliplatin (NAC-mFFX) and neoadjuvant chemotherapy based on abraxane/gemcitabine (NAC-AG) ranked first and second in OS for RPC/BRPC. CONCLUSIONS: Both RPC and BRPC could obtain OS benefits from neoadjuvant therapy compared with UP-S, and NAC improved OS both in RPC and BRPC while NACR only improved OS in BRPC. Furthermore, NAC was superior to NACR, and NAC-mFFX and NAC-AG might be recommended sequentially as the best neoadjuvant therapy strategies.

OBJECTIVES: This study aimed to assess the efficacy of Aidi combined with standard treatment, including radiotherapy (R), chemotherapy (C), or chemoradiotherapy (CR), for unresectable esophageal cancer (EC). METHODS: Eight online databases were queried to collect randomized controlled trials (RCTs) published from database construction to August 2022. Patients in the control group underwent standard treatment with R, C, or CR, whereas those in the experimental group underwent Aidi combined with standard treatment. RESULTS: In this meta-analysis, 29 reports with 2079 patients were included. The results showed that the Aidi-based combination therapy groups had higher objective response rates (ORRs), disease control rates (DCRs), one-year overall survival (OS) and improvement and stability of Karnofsky performance status (KPS) than the control group (risk ratio (RR) = 1.24 (95% CI = 1.17-1.33), 1.09 (95% CI = 1.05-1.14), 1.50 (95% CI = 1.31-1.72), and 1.28 (95% CI = 1.16-1.41)). The Aidi-based combination therapy groups also had lower total incidence rates of bone marrow suppression (BMS), chemotherapy-induced nausea and vomiting (CINV) and radiation esophagitis (RE) than the control group (RR = 0.48 (95% CI = 0.41-0.56), 0.46 (95% CI = 0.36-0.58), and 0.49 (95% CI = 0.38-0.62)). In addition, subgroup analysis suggested that the optimal dose and cycle of Aidi injection combined therapy was 80-100 ml/time and 30 days/2 cycles. The efficacy of Aidi combined with DP (docetaxel + cisplatin) was better than the Aidi combined with PF (cisplatin plus fluorouracil). CONCLUSION: Aidi-based combination therapy showed high efficacy for unresectable EC treatment and reduced the incidence rates of adverse events. However, further studies including higher-quality RCTs are needed to validate these findings. TRIAL REGISTRATION NUMBER: INPLASY 202290020.

INTRODUCTION: With increased social isolation due to COVID-19, social media has been increasingly adopted for communication, education, and entertainment. We sought to understand the frequency and characteristics of social media usage among general surgery trainees. MATERIALS AND METHODS: General surgery trainees in 15 American training programs were invited to participate in an anonymous electronic survey. The survey included questions about demographics, frequency of social media usage, and perceptions of risks and benefits of social media. Univariate analysis was performed to identify differences between high users of social media (4-7 h per week on at least one platform) and low users (0-3 h or less on all platforms). RESULTS: One hundred fifty-seven of 591 (26.6%) trainees completed the survey. Most respondents were PGY3 or lower (75%) and high users of social media (74.5%). Among high users, the most popular platforms were Instagram (85.7%), YouTube (85.1%), and Facebook (83.6%). YouTube and Twitter were popular for surgical education (77.3% and 68.2%, respectively). The most reported benefits of social media were improving patient education and professional networking (85.0%), where high users agreed more strongly about these benefits (P = 0.002). The most reported risks were seeing other residents (42%) or attendings (17%) with unprofessional behavior. High users disagreed more strongly about risks, including observing attendings with unprofessional behavior (P = 0.028). CONCLUSIONS: Most respondents were high users of social media, particularly Instagram, YouTube, and Facebook. High users incorporated social media into their surgical education while perceiving more benefits and fewer risks of social media.

BACKGROUND: Development of a deep learning method to identify Barrett's esophagus (BE) scopes in endoscopic images. METHODS: 443 endoscopic images from 187 patients of BE were included in this study. The gastroesophageal junction (GEJ) and squamous-columnar junction (SCJ) of BE were manually annotated in endoscopic images by experts. Fully convolutional neural networks (FCN) were developed to automatically identify the BE scopes in endoscopic images. The networks were trained and evaluated in two separate image sets. The performance of segmentation was evaluated by intersection over union (IOU). RESULTS: The deep learning method was proved to be satisfying in the automated identification of BE in endoscopic images. The values of the IOU were 0.56 (GEJ) and 0.82 (SCJ), respectively. CONCLUSIONS: Deep learning algorithm is promising with accuracies of concordance with manual human assessment in segmentation of the BE scope in endoscopic images. This automated recognition method helps clinicians to locate and recognize the scopes of BE in endoscopic examinations.

BACKGROUND: Hypertrophic osteoarthropathy (HOA) is a musculoskeletal pathology that often occurs as a paraneoplastic syndrome. 90% of HOA cases occur secondary to malignancy. 60 to 80% of which are lung cancers. CASE REPORT: We present a case of a 61-year-old man who had worsening knee pain. HOA was incidentally noted on extremity X-ray. The patient was found to have a soft-tissue attenuating mass on chest X-ray. The diagnosis of non-small cell lung cancer was made after bronchoscopy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: HOA can be an indication of malignancy, most commonly lung cancer, so it is important to recognize the key radiographic findings associated with HOA. When treating patients with bone pain and clubbed digits, emergency physicians should strongly consider screening for more severe primary pathology.

Background: Prior research has indicated a link between psoriasis and the susceptibility to breast cancer (BC); however, a definitive causal relationship remains elusive. This study sought to elucidate the causal connection and shared underlying mechanisms between psoriasis and BC through bidirectional Mendelian randomization (MR) and bioinformatic approaches. Methods: We employed a bidirectional MR approach to examine the potential causal connection between psoriasis and BC. Genetic data pertaining to psoriasis and BC were sourced from extensive published genome-wide association studies. The inverse -variance weighted or wald ratio served as the primary method for estimating causal effects. Sensitivity analysis of the MR results was applied with multiple methods. Leveraged datasets from the Gene Expression Omnibus and the Cancer Genome Atlas repositories to identify common differentially expressed genes, shedding light on the shared mechanisms underlying these two conditions. Results: The MR analysis revealed that when considering psoriasis as an exposure factor, the incidences of BC (OR=1.027) and estrogen receptor negative (ER-) BC (OR=1.054) were higher than in the general population. When using Her2+ BC as an exposure factor, the risk of psoriasis was 0.822 times higher (OR=0.822) than in the general population. Sensitivity analysis indicated that the results were robust. Transcriptome analysis showed that CXCL13 and CCL20 were activated in both BC and psoriasis. Both diseases were also linked to neutrophil chemotaxis, the IL-17 pathway, and the chemokine pathway. Conclusion: The results suggest that psoriasis may increase the risk of BC, especially ER- BC, while reverse MR suggests a decreased risk of psoriasis in Her2+ BC. Transcriptome analysis revealed a shared mechanism between psoriasis and BC.

BACKGROUND: Long-term physical and mental persistent symptoms after COVID-19 represent a growing global public health concern. However, there remains a substantial knowledge gap regarding their prevalence and risk factors. OBJECTIVES: To estimate the prevalence and risk factors for persistent symptoms after COVID-19. METHODS OF DATA SYNTHESIS: We used a random-effects model to pool persistent symptom prevalence and risk ratios comparing COVID-19 patients with non-COVID-19 individuals. DATA SOURCES: Electronic databases were searched for studies published from December 2019 to January 2023. STUDY ELIGIBILITY CRITERIA: Eligible studies that reported the prevalence and risk factors for persistent symptoms after COVID-19 were included. PARTICIPANTS: Patients who recovered from COVID-19. ASSESSMENT OF RISK OF BIAS: The Joanna Briggs Institute critical appraisal tool was used to assess the risk of bias in prevalence studies, whereas the risk of bias in cohort studies was evaluated with the Newcastle-Ottawa Scale. RESULTS: After screening 4359 studies, a total of 211 eligible studies were included, covering a population of 13 368 074 individuals. Fatigue, dyspnoea, post-traumatic stress disorder, anxiety, and depression were the most frequently reported persistent symptoms after COVID-19. Subgroup analyses revealed that individuals with more severe illness in the acute phase or from Europe exhibited a higher prevalence of certain symptoms, whereas children demonstrated a lower prevalence. Furthermore, COVID-19 patients had a significantly higher prevalence of most persistent symptoms compared with non-COVID-19 individuals. Factors frequently associated with a higher prevalence of persistent symptoms included female gender, advanced age, severe illness during the acute phase of COVID-19, multiple comorbidities, an extended duration of hospital stay, and a high body mass index. CONCLUSION: This meta-analysis provides a thorough review of the prevalence and risk factors for persistent symptoms following COVID-19. The findings underscore the importance of long-term monitoring and support for individuals recovering from COVID-19.

Benign gallbladder diseases are common in surgery department, and the laparoscopic cholecystectomy (LC) is the gold standard procedure for benign diseases of gallbladder. Laparoscopic cholecystectomy is conventionally performed using four laparoscopic ports. However, the clinical application of different LCs is equivocal and there is no comprehensive comparison to explore which surgical options could benefit patients with benign gallbladder diseases. A network meta-analysis (NMA) to evaluate the efficacy of the different LCs could benefit patients with benign gallbladder diseases by comprehensive comparison. A systematic literature search was performed using PubMed, Embase, and Cochran Library. Totally, 17 randomized controlled trials (RCTs) (n = 1627) met study selection criteria and were incorporated in this NMA study. The first ranking probabilities of the five surgical options to alleviate postoperative pain scores were: 54.4% for single-incision robotic cholecystectomy (SIRC), 25.2% for single-incision laparoscopic cholecystectomy (SALC), and 24.9% for mini-laparoscopic cholecystectomy (Mini). The first ranking probabilities for reducing postoperative complications in the surgical options were: 61.3% for three-port laparoscopic cholecystectomy and 21.8% for four-port laparoscopic cholecystectomy. The first ranking probabilities for reducing hospital stay(days) in the surgical options were: 32.3% for SIRC, 29.0% for three-port laparoscopic cholecystectomy and 19.8% for four-port laparoscopic cholecystectomy. The first ranking probabilities for reducing operation time showed that the three-port technique had the shortest operation time, followed by three-port laparoscopic cholecystectomy (51.3%), four-port laparoscopic cholecystectomy (26.8%), and mini-laparoscopic cholecystectomy (21.6%). Our study found that the optimal surgical plan for different outcomes varies, making it difficult to give a comprehensive recommendation. Three-port laparoscopic cholecystectomy and four-port laparoscopic cholecystectomy may be the best options in terms of reducing surgical complications and operative time. Meanwhile, SIRC is the best options for relieving postoperative pain relief. SIRC and three-port laparoscopic cholecystectomy can reduce hospital stay (days) compared other LCs.

Xanthogranulomatous inflammation (XGI) is a rare, benign condition that can affect several organs, including the gallbladder, kidney, skin, gastrointestinal tract, lymph nodes, and soft tissues. It is often misdiagnosed as a malignancy. In this report, we present the case of a 79-year-old male who presented with persistent jaundice for 11 months. Computed tomography and magnetic resonance imaging revealed pancreatic head enlargement, gallbladder thickening, and common bile duct thickening, leading to a preoperative diagnosis of malignant neoplasm of the pancreatic head. During surgery, dense adhesions were found around the portal vein, suggestive of mass invasion. To relieve obstruction, choledochojejunostomy was performed. Postoperative pathological examination revealed xanthogranulomatous cholecystitis (XGCc), xanthogranulomatous cholangitis (XGCg), and xanthogranulomatous pancreatitis (XGP). XGI affecting the bile ducts and pancreas is extremely rare, and there are no reported cases of simultaneous involvement of the gallbladder, bile duct, and pancreas by XGI. This study provides valuable insight into the differential diagnosis of XGI by presenting the imaging features of XGI patients.
RESUMO
Background: Modified fluorouracil/leucovorin/irinotecan/oxaliplatin (FOLFIRINOX) regimen (mFOLFIRINOX), comprised of fluorouracil, leucovorin, irinotecan and oxaliplatin, is the first-line standard chemotherapy in patients with advanced pancreatic cancer. The S-1/oxaliplatin/irinotecan (SOXIRI) regimen has also been studied recently under similar conditions. This study compared its efficacy and safety. Methods: All cases of locally advanced or metastatic pancreatic cancer treated with the SOXIRI or mFOLFIRINOX regimen in Sun Yat-sen University Cancer Centre from July 2012 to June 2021 were reviewed retrospectively. The data of patients who satisfied the inclusion criteria were compared between two cohorts, including overall survival (OS), progression-free survival (PFS), objective response rate, disease control rate and safety. Results: A total of 198 patients were enrolled in the study, including 102 patients treated with SOXIRI and 96 patients treated with mFOLFIRINOX. There was no significant difference in OS [12.1 months versus 11.2 months, hazard ratio (HR) = 1.04, p = 0.81] or PFS (6.5 months versus 6.8 months, HR = 0.99, p = 0.96) between patients treated with SOXIRI and mFOLFIRINOX. In the subgroup analysis, patients with slightly elevated baseline total bilirubin (TBIL) or underweight patients before chemotherapy were more likely to have a longer OS or PFS from SOXIRI than from mFOLFIRINOX. In addition, the carbohydrate antigen (CA)19-9 decline was a good predictor for the efficacy and prognosis of both chemotherapy regimens. All grade adverse events were parallel in all kinds of toxicities except that anaemia was more common in the SOXIRI group than in the mFOLFIRINOX group (41.4% versus 24%, p = 0.03). The occurrence of any grade 3 to 4 toxicity was similar in the two groups. Conclusions: For locally advanced or metastatic pancreatic cancer patients, the SOXIRI regimen had similar efficacy and controllable safety compared with the mFOLFIRINOX regimen.
RESUMO
Background: Negative regional lymph nodes do not indicate a lack of distant metastasis. A considerable number of patients with negative regional lymph node pancreatic cancer will skip the step of regional lymph node metastasis and directly develop distant metastasis. Methods: We retrospectively analyzed the clinicopathological characteristics of patients with negative regional lymph node pancreatic cancer and distant metastasis in the Surveillance, Epidemiology, and End Results database from 2010 to 2015. Multivariate logistic analysis and Cox analysis were used to determine the independent risk factors that promoted distant metastasis and the 1-, 2-, and 3-year cancer-specific survival in this subgroup. Results: Sex, age, pathological grade, surgery, radiotherapy, race, tumor location, and tumor size were significantly correlated with distant metastasis (P < 0.05). Among these factors, pathological grade II and above, tumor site other than the pancreatic head, and tumor size >40 mm were independent risk factors for distant metastasis; age ≥60 years, tumor size ≤21 mm, surgery, and radiation were protective factors against distant metastasis. Age, pathological grade, surgery, chemotherapy, and metastasis site were identified as predictors of survival. Among them, age ≥40 years, pathological grade II and above, and multiple distant metastasis were considered independent risk factors for cancer-specific survival. Surgery and chemotherapy were considered protective factors for cancer-specific survival. The prediction performance of the nomogram was significantly better than that of the traditional American Joint Committee on Cancer tumor, node, metastasis staging system. We also established an online dynamic nomogram calculator, which can predict the survival rate of patients at different follow-up time points. Conclusion: Pathological grade, tumor location, and tumor size were independent risk factors for distant metastasis in pancreatic ductal adenocarcinoma with negative regional lymph nodes. Older age, smaller tumor size, surgery, and radiotherapy were protective factors against distant metastasis. A new nomogram that was constructed could effectively predict cancer-specific survival in pancreatic ductal adenocarcinoma with negative regional lymph nodes and distant metastasis. Furthermore, an online dynamic nomogram calculator was established.
RESUMO
BACKGROUND: Both inflammatory bowel disease (IBD) and hepato-pancreato-biliary cancers (HPBC) have been established to cause a huge socioeconomic burden. Epidemiological studies have revealed a close association between IBD and HPBC. METHODS: Herein, we utilized inverse-variance weighting to conduct a two-sample Mendelian randomization analysis. We sought to investigate the link between various subtypes of IBD and HPBC. To ensure the accuracy and consistency of our findings, we conducted heterogeneity tests, gene pleiotropy tests, and sensitivity analyses. RESULTS: Compared to the general population, IBD patients in Europe exhibited a 1.22-fold increased incidence of pancreatic cancer (PC) with a 95% confidence interval (CI) of 1.0022-1.4888 (p = 0.0475). We also found a 1.14-fold increased incidence of PC in Crohn's disease (CD) patients with (95% CI: 1.0017-1.3073, p = 0.0472). In the East Asian population, the incidence of hepatocellular carcinoma (HCC) was 1.28-fold higher (95% CI = 1.0709-1.5244, p = 0.0065) in IBD patients than in the general population. Additionally, ulcerative colitis (UC) patients displayed 1.12-fold (95% CI: 1.1466-1.3334, p < 0.0001) and 1.31-fold (95% CI: 1.0983-1.5641, p = 0.0027) increased incidences of HCC and cholangiocarcinoma (CCA), respectively. Finally, the incidence of PC was 1.19-fold higher in CD patients than in the general population (95% CI = 1.0741-1.3132, p = 0.0008). CONCLUSION: Our study validated that IBD is a risk factor for HPBC. This causal relationship exhibited significant heterogeneity in different European and East Asian populations.

Introduction: Gliomas, the most prevalent tumors of the central nervous system, are known for their aggressive nature and poor prognosis. The heterogeneity among gliomas leads to varying responses to the same treatments, even among similar glioma types. In our study, we efferocytosis-related subtypes and explored their characteristics in terms of immune landscape, intercellular communication, and metabolic processes, ultimately elucidating their potential clinical implications. Methods and Results: We first identified efferocytosis-related subtypes in Bulk RNA-seq using the NMF algorithm. We then preliminarily demonstrated the correlation of these subtypes with efferocytosis by examining enrichment scores of cell death pathways, macrophage infiltration, and the expression of immune ligands. Our analysis of single-cell RNA-seq data further supported the association of these subtypes with efferocytosis. Through enrichment analysis, we found that efferocytosis-related subtypes differ from other types of gliomas in terms of immune landscape, intercellular communication, and substance metabolism. Moreover, we found that the efferocytosis-related classification is a prognostic factor with robust predictive performance by calculating the AUC values. We also found that efferocytosis-related subtypes, when compared with other gliomas in drug sensitivity, survival, and TIDE scores, show a clear link to the effectiveness of chemotherapy, radiotherapy, and immunotherapy in glioma patients. Discussion: We identified efferocytosis-related subtypes in gliomas by analyzing the expression of 137 efferocytosis-associated genes, exploring their characteristics in immune landscape, intercellular communication, metabolic processes, and genomic variations. Moreover, we discovered that the classification of efferocytosis-related subtypes has a strong prognostic predictive power and holds potential significance in guiding clinical treatment.
RESUMO
Background: Anti-programmed cell death protein 1 and its ligand (anti-PD1/PDL1) have been proposed as a promising therapeutic option for advanced biliary tract cancer (aBTC). Given the scarce quantitative analyses of anti-PD1/PDL1 in aBTC, we thus did a meta-analysis to assess the benefits and risks of this emerging treatment strategy in patients with aBTC. Methods: PubMed, Embase, the Cochrane Library, Web of Science, and meeting resources were searched for relevant studies. The main endpoints were median progression-free survival (mPFS), median overall survival (mOS), objective response rate (ORR), disease control rate (DCR), any-grade adverse events (AEs), and grade 3-4 AEs. Results: Twenty-eight studies with 1,338 participants were included. The best curative effect was found in the anti-PD1/PDL1 combined with anti-CTLA4 and chemotherapy group (mPFS: 12.4 months; mOS: 16.0 months; ORR: 45.1%; DCR: 95.0%), followed by the anti-PD1/PDL1 plus chemotherapy group (mPFS: 8.2 months; mOS: 14.8 months; ORR: 36.3%; DCR: 84.6%), the anti-PD1/PDL1 plus antiangiogenesis group (mPFS: 4.9 months; mOS: 10.2 months; ORR: 17.5%; DCR: 68.7%), the anti-PD1/PDL1 plus anti-cytotoxic T lymphocyte antigen 4 (anti-CTLA4) group (mPFS: 2.9 months; mOS: 8.3 months; ORR: 9.9%; DCR: 36.8%), and the anti-PD1/PDL1 monotherapy group (mPFS: 2.5 months; mOS: 7.6 months; ORR: 6.8%; DCR: 34.7%). Compared with anti-PD1-containing regimens, anti-PDL1-containing regimens achieved preferable mPFS (11.1 vs. 3.8 months), mOS (12.2 vs. 9.8 months), and ORR (23.7% vs. 17.4%), despite a similar DCR (61.1% vs. 61.3%). The mPFS, mOS, ORR, and DCR were 10.6 months, 15.8 months, 42.3%, and 88.6% of first-line anti-PD1/PDL1 and 3.0 months, 9.1 months, 11.6%, and 51.1% of second-line therapy or beyond, respectively. There were 80.6% and 34.0% of the patients suffering any-grade AEs and grade 3-4 AEs. Anti-PD1/PDL1 monotherapy might be considered as a safer alternative than combination regimens. Meanwhile, obvious toxicities in the first-line setting could not be neglected. Conclusions: Anti-PD1/PDL1 showed encouraging efficacy and acceptable safety profile in aBTC and, thus, could be an alternative treatment.

This study aimed to evaluate the efficacy of nourishing Yin and clearing heat therapy (NYCH therapy) based on traditional Chinese medicine (TCM) in the treatment of radiotherapy-induced oral mucositis (RTOM) in nasopharyngeal carcinomas (NPCs). A total of eight online databases were searched from inception to September 2021 for randomized controlled trials (RCTs). The control group was treated with Western medicine (WM) alone, whereas the experimental group was treated with a combined NYCH and WM therapy. A total of 30 RCTs involving 2562 participants were ultimately included. NYCH therapy combined with conventional WM delayed the onset time (days) of RTOM (MD = 10.80, p < 0.001), and at that time, a higher cumulative radiotherapy dose (Gy) (MD = 5.72, p < 0.001) was completed in the experimental group. The combination regimen also reduced the incidence of severe oral mucositis (Grade III-IV) (RR = 0.25, p < 0.001). In addition, the treatment efficacy of the experimental group was significantly better than that of the control group (RR = 1.31, p < 0.001). Compared with the patients in the control group, the experimental group had lower xerostomia scores (MD = -1.07, p < 0.001) and more saliva (MD = 0.36, p < 0.001). NYCH combined with WM improved the efficacy of treating RTOM in NPC. This study provides a sufficient basis for conducting further large RCTs to prove the efficacy of NYCH.
