Abstract
BACKGROUND Narrow-band imaging (NBI) endoscopy is used in various tumor detection and is important in detecting early tumors. OBJECTIVE To explore the application value of NBI endoscopy in diagnosing pharyngeal tumors. MATERIAL AND METHODS Ninety-one patients with pharyngeal masses who attended the Department of Otorhinolaryngology, Head and Neck Surgery in Gansu Provincial Hospital from January 2023 to February 2024 were selected, and NBI and white light (WL) endoscopy were applied to examine the pharynx and the relationship between the two was observed. SPSS 25.0 software was used for statistical analysis. RESULTS The sensitivity of NBI endoscopy for diagnosing laryngeal malignant lesions was 92.0 %, the specificity was 93.0 %, the positive predictive value was 88.5 %, and the negative predictive value was 95.2 %, with a high degree of concordance between the results of NBI endoscopy and the pathology; WL endoscopy had a sensitivity of 64.0 %, a specificity of 76. 7 %, a positive predictive value of 61.5 %, and a negative predictive value of 78.6 %, with WL endoscopic findings had moderate concordance with pathology. The diagnostic accuracy of NBI endoscopy was higher than that of WL endoscopy for both benign and malignant lesions and precancerous lesions. CONCLUSION NBI endoscopy can detect laryngeal cancer lesions more accurately.

Abstract
BACKGROUND First identified in Drosophila melanogaster, the Hippo pathway is considered a major regulatory cascade controlling tissue homeostasis and organ development. Hippo signaling components include kinases whose activity regulates YAP and TAZ final effectors. In response to upstream stimuli, YAP and TAZ control transcriptional programs involved in cell proliferation, cytoskeletal reorganization and stemness. MAIN TEXT While fine tuning of Hippo cascade components is essential for maintaining the balance between proliferative and non-proliferative signals, pathway signaling is frequently dysregulated in gastrointestinal cancers. Also, YAP/TAZ aberrant activation has been described in conditions characterized by chronic inflammation that precede cancer development, suggesting a role of Hippo effectors in triggering carcinogenesis. In this review, we summarize the architecture of the Hippo pathway and discuss the involvement of signaling cascade unbalances in premalignant lesions of the gastrointestinal tract, providing a focus on the underlying molecular mechanisms. CONCLUSIONS The biology of premalignant Hippo signaling dysregulation needs further investigation in order to elucidate the evolutionary trajectories triggering cancer inititation and develop effective early therapeutic strategies targeting the Hippo/YAP pathway.

Abstract
BACKGROUND AND PURPOSE Patients with stage III or IV of operative link for gastric intestinal metaplasia assessment (OLGIM) are at a higher risk of gastric cancer (GC). We aimed to construct a deep learning (DL) model based on magnifying endoscopy with narrow-band imaging (ME-NBI) to evaluate OLGIM staging. METHODS This study included 4473 ME-NBI images obtained from 803 patients at three endoscopy centres. The endoscopic expert marked intestinal metaplasia (IM) regions on endoscopic images of the target biopsy sites. Faster Region-Convolutional Neural Network model was used to grade IM lesions and predict OLGIM staging. RESULTS The diagnostic performance of the model for IM grading in internal and external validation sets, as measured by the area under the curve (AUC), was 0.872 and 0.803, respectively. The accuracy of this model in predicting the high-risk stage of OLGIM was 84.0%, which was not statistically different from that of three junior (71.3%, p = 0.148) and three senior endoscopists (75.3%, p = 0.317) specially trained in endoscopic images corresponding to pathological IM grade, but higher than that of three untrained junior endoscopists (64.0%, p = 0.023). CONCLUSION This DL model can assist endoscopists in predicting OLGIM staging using ME-NBI without biopsy, thereby facilitating screening high-risk patients for GC.

Abstract
Members of the Protein kinase D (PKD) kinase family each play important cell-specific roles in the regulation of normal pancreas functions. In pancreatic diseases PKD1 is the most widely characterized isoform with roles in pancreatitis and in induction of pancreatic cancer and its progression. PKD1 expression and activation increases in pancreatic acinar cells through macrophage secreted factors, Kirsten rat sarcoma viral oncogene homolog (KRAS) signaling, and reactive oxygen species (ROS), driving the formation of precancerous lesions. In precancerous lesions PKD1 regulates cell survival, growth, senescence, and generation of doublecortin like kinase 1 (DCLK1)-positive cancer stem cells (CSCs). Within tumors, regulation by PKD1 includes chemoresistance, apoptosis, proliferation, CSC features, and the Warburg effect. Thus, PKD1 plays a critical role throughout pancreatic disease initiation and progression.

Abstract
BACKGROUND The single-visit strategy, also known as the "screen-and-treat" approach, is widely used to screen for cervical cancer in low- and middle-income countries. The screen-and-treat approach leads to unnecessary or inadequate treatment. Thus, a study was conducted to determine the histopathological patterns of aceto-white lesions on visual inspection with acetic acid (VIA) in patients who underwent a Loop Electrosurgical Excision Procedure (LEEP) at Bugando Medical Centre between January 2016 and December 2020. METHOD A 5-year retrospective cross-sectional case record review was conducted on 329 women who had LEEP at Bugando Medical Centre following a positive VIA cervical screening test. A standard data abstraction form was used to collect patient information. Missing client information records and LEEP without histopathological results were exclusion criteria. For statistical analysis, STATA version 15 was used; in descriptive statistics, frequency, mean, and standard deviation were used. The Chi2 and Fisher's exact tests were used to investigate the relationship between patient characteristics and histopathological patterns, and a P-value of 0.05 was considered statistically significant in multinomial models. RESULTS This study looked at 329 patients who had LEEP following a VIA positive but were not eligible for cryotherapy. Our study participants had a mean age of 40 ± 8.2 SD. There were 203 (61.7%) patients with benign lesions, including 4 with schistosomiasis and 2 with cervical tuberculosis. The precancerous lesions were discovered in 100 cases (30.4%), and 26 (7.9%) already had invasive cervical cancer. Out of 100 patients with precancerous lesions, 58 (17.6%) and 42 (12.8%) have high- and low-grade squamous intraepithelial (HSIL and LSIL) lesions, respectively. The presence of a precancerous lesion was found to be associated with age 31-40 years (P-value 0.042) and HIV positivity (P-value 0.004). CONCLUSION Most patients in this study had benign cervical lesions, which do not require LEEP treatment. Nonetheless, a considerable percentage of invasive cervical malignancies and rare benign diseases such as schistosomiasis and cervical tuberculosis were identified. A screen-and-treat approach within well-equipped tertiary hospitals like Bugando Medical Centre should explore alternative options instead of relying solely on straight LEEP.

Abstract
BACKGROUND In Sub-Saharan Africa, the prevalence of dyslipidemia is on the rise, with studies showing dyslipidemia as a contributing factor to the progression of premalignant lesions to cervical cancer. In Uganda, cervical cancer and dyslipidemia are common health concerns, considering the increasing trends of dyslipidemia in the general population and inadequate information regarding dyslipidemia and cervical lesions. This study aimed to determine the prevalence of dyslipidemia and its association with precancerous and cancerous lesions of the cervix among women attending a cervical cancer clinic at the Uganda Cancer Institute. METHODS This cross-sectional study was conducted from February to April 2022 among women with premalignant and malignant lesions of the cervix. Data on social demographics and health-seeking behaviours were collected using a pretested structured questionnaire after written informed consent had been obtained. Pap smear collection preceded visual inspection with acetic acid; cervical biopsies were collected appropriately from eligible participants; and cervical lesions were classified using the Bethesda system 2014. Serum lipids, total cholesterol (T.C.), high-density lipoprotein (HDLc), low-density lipoprotein (LDLc), and triglycerides (T.G.s) were analysed using the COBAS™ 6000 Clinical Chemistry Analyser. The associations were assessed using the chi-square test, and P ≤ 0.05 was considered statistically significant. RESULTS The overall prevalence of dyslipidemia among women with cervical lesions was 118/159 (74%), and low HDLc was the most prevalent at 64.6% (95% CI 39.0-54.3). High T.C. (P = 0.05), high T.G.s (P = 0.011), and low HDL-c (P = 0.05) showed a significant association with precancerous lesions. High LDL-c (P = 0.019), high T.G.s (P = 0.02), and high T.G.s (P < 0.001) showed a statistically significant association with cancerous lesions. CONCLUSION The prevalence of dyslipidemia was high, with high TC, T.G.s, and low HDL-c significantly associated with precancerous lesions. Also, elevated T.G.s and high LDLc were significantly associated with cancerous lesions. Women may benefit from dyslipidemia screening along with cervical cancer screening. WHAT THIS STUDY ADDS The present study builds upon previous findings suggesting a link between dyslipidemia and cervical lesions by investigating the relationship between these two factors, specifically in women of this geographical location, where we need adequate information on these associations.

Abstract
According to the latest statistical data, the incidence and mortality rate of hepatocellular carcinoma in China are still on the rise, posing a major threat to the health of the Chinese population. The occurrence is closely related to the formation of precancerous lesions in the liver. The clinical and basic research on precancerous lesions of hepatocellular carcinoma has developed rapidly, and the concepts and specific techniques for diagnosis and treatment have also undergone new changes and advancements. Therefore, based on the first version in 2020, this consensus has organized multidisciplinary experts to compile and improve a new version by integrating the latest progress in their respective professional fields at home and abroad. It aims to enhance clinicians' understanding of precancerous lesions of hepatocellular carcinoma standardize the pathology, imaging, and molecular diagnostic criteria, broaden early screening methods, formulate scientifically rational treatment plans, and help promote the advancement of diagnosis and treatment strategies and to enhance the overall 5-year survival rate of patients with hepatocellular carcinoma.

Abstract
OBJECTIVE To identify risk factors for precancerous cervical lesions and factors associated with treatment delay among women in the rural Busoga Region, Uganda. STUDY DESIGN A retrospective cross-sectional study from a regional cervical cancer screening program and from cervical cancer patients enrolled in a region-wide palliative care program. METHODS Logistic regression analysis was conducted to assess risk factors for screening positive for precancerous lesions. In a separate analysis, factors associated with treatment delay were assessed among women enrolled in the palliative care program. RESULTS Three thousand nine hundred forty-six women were included from the screening program and 334 from the palliative care program. In total, 7.6% of screening participants had precancerous lesions. Within Busoga Region, the highest positivity rate was found in Bugweri and Namayingo Districts. Abnormal vaginal bleeding (adjusted odds ratio [aOR] 1.60; 95% confidence interval [CI] 1.15-2.21; p = 0.005) and older age at first menstrual period (aOR 1.08; 95% CI 1.01-1.16; p = 0.03) were associated with having a precancerous lesion. Among palliative care patients, a history of previous contact with the health care system was associated with a delay in enrolment (≥12 months from first symptom presentation until commencement in palliative care; aOR 5.23; 95% CI 1.16-36.54; p = 0.047). CONCLUSIONS The results underline an unmet need for broad-scale cervical cancer screening focusing on all women in the reproductive age. Abnormal bleeding was the only substantial risk factor for precancerous lesions, indicating that specific algorithms to identify high-risk populations may not be applicable in this population. Increased awareness, resources, and funding are still necessary to achieve global cervical cancer elimination.

Abstract
PURPOSE This large-scale, multicenter, retrospective observational study aimed to evaluate the clinicopathological and molecular profiles associated with programmed death-ligand 1 (PD-L1) expression in precancerous lesions and invasive adenocarcinoma in subcentimeter pulmonary nodules. PATIENTS AND METHODS Patients with histologically confirmed atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma (ADC) were included. PD-L1 expression was evaluated at each center using a PD-L1 immunohistochemistry 22C3 pharmDx kit (Agilent, Santa Clara, CA, USA). The tumor proportion score (TPS) cutoff values were set at ≥ 1% and ≥ 50%. RESULTS A total of 2022 nodules from 1844 patients were analyzed. Of these, 9 (0.45%) nodules had PD-L1 TPS ≥ 50%, 187 (9.25%) had PD-L1 TPS 1-49%, and 1826 (90.30%) had PD-L1 TPS < 1%. A total of 378 (18.69%), 1016 (50.25%), and 628 (31.06%) nodules were diagnosed as AAH/AIS, MIA, and ADC, respectively, by pathology. A total of 1377 (68.10%), 591 (25.67%), and 54 (2.67%) nodules were diagnosed as pure ground-glass opacity (GGO), mixed GGO, and solid nodules, respectively, by computed tomography. There was a significant difference between PD-L1 expression and anaplastic lymphoma kinase (ALK) mutation status (P < 0.001). PD-L1 expression levels were significantly different from those determined using the International Association for the Study of Lung Cancer (IASLC) grading system (P < 0.001). CONCLUSIONS PD-L1 expression was significantly associated with radiological and pathological invasiveness and driver mutation status in subcentimeter pulmonary nodules. The significance of PD-L1 expression in the evolution of early-stage lung adenocarcinoma requires further investigation.

Abstract
BACKGROUND Squamous cell lung cancer (SCLC) arises from bronchial changes: basal cell hyperplasia (BCH), squamous metaplasia (SM), and dysplasia. However, the premalignant process preceding SCLC is not inevitable; it can stop at any of the bronchial lesions. Previously, we hypothesized that combinations of premalignant lesions observed in the small bronchi of SCLC patients can reflect the different "scenarios" of the premalignant process: BCHi-the stoppage at the stage of hyperplasia and BCHSM-the progression of hyperplasia to metaplasia. METHODS AND RESULTS In this study, using whole-genome bisulfite sequencing we analyzed the DNA methylome of two forms of BCH: isolated BCH (BCHi) and BCH co-occurred with SM (BCHSM) in the small bronchi of SCLC patients. It was shown that BCHi harbored differentially methylated regions (DMRs) affecting genes associated with regulating phosphatase activity. In BCHSM, DMRs were found in genes involved in PI3K-Akt and AMPK signaling pathways. DMRs were also found to affect specific miRNA genes: miR-34a and miR-3648 in BCHi and miR-924 and miR-100 in BCHSM. CONCLUSIONS Thus, this study demonstrated the significant changes in DNA methylome between the isolated BCH and BCH combined with SM. The identified epigenetic alterations may underlie different "scenarios" of the premalignant process in the bronchial epithelium.

Abstract
BACKGROUND Cervical cancer continues to generate a significant burden of disease and death in low- and middle-income countries (LMICs). Lack of awareness and poor access to early screening and pre-cancer treatment contribute to the high mortality. We describe here cervical cancer screening outcomes in public health facilities in three states in Nigeria. METHODS We conducted an observational study in 177 government health facilities in Lagos, Kaduna, and Rivers State, Nigeria from January to December 2021, in which we reviewed programmatic data collected through the newly introduced Cervical Cancer Prevention Program. Women who received screening and provided consent were enrolled into the study. Data were extracted from registers in the health facilities using SurveyCTO and descriptive statistical analysis was conducted using StataSE 15 (StataCorp, College Station, TX, USA). RESULTS Eighty-three thousand, five hundred ninety-three women were included in the analysis including 6,043 (7%) WLHIV. 67,371 (81%) received VIA as their primary screening while 16,173 (19%) received HPV DNA testing, with 49 (< 1%) receiving both at the same time. VIA positivity was 7% for WLHIV and 3% for general population, while HPV prevalence was 16% for WLHIV and 8% for general population. Following a positive HPV result, 21% of women referred, completed triage examination. 96% of women identified with precancerous lesions, received treatment. 44% of women with suspected cancer were successfully referred to an oncology center for advanced treatment. Following treatment with thermal ablation, seven adverse events were reported. CONCLUSIONS The Program has successfully increased women's access to screening and treatment of precancerous lesions. Almost all women who were eligible for pre-cancerous lesion treatment received it, often on the same day when screened using VIA. However, for women referred for a triage exam or due to suspected cancer, many did not complete their referral visits. More effort is required to ensure HPV positive women and women with suspected cancer are adequately linked to care to further reduce morbidity and mortality associated with cervical cancer in Nigeria. Implementation studies should be conducted to provide insights to improve the utilization of the existing centralized and point of care (POC) platforms to facilitate same day results, and to improve triage and treatment rates.

Abstract
BACKGROUND Risk stratification for patients with gastric precancerous lesions for endoscopic surveillance remains controversial.
AIM To analysis of patients having developed gastric adenocarcinoma during the period of follow-up.
METHODS We conducted a retrospective study on patients having undergone upper endoscopy prior to the development of gastric adenocarcinoma. The presence and stage of precancerous lesions as well as subtype of intestinal metaplasia at the baseline endoscopy got evaluated. Literature mini-review was performed.
RESULTS Out of 1681 subjects in the Biobank, gastric adenocarcinoma was detected in five cases in whom previous endoscopy data with biopsies either from the corpus or antral part were available. All of the patients had incomplete intestinal metaplasia during the baseline endoscopy; all three subjects in whom intestinal metaplasia subtyping was performed according to Filipe et al, had Type III intestinal metaplasia. Two of the five cases had low Operative Link on Gastritis Assessment (OLGA) and Operative Link on Gastritis Intestinal Metaplasia Assessment (OLGIM) stages (I-II) at the baseline.
CONCLUSION The presence of incomplete intestinal metaplasia, in particular, that of Type III is a better predictor for gastric adenocarcinoma development than OLGA/OLGIM staging system. Subtyping of intestinal metaplasia have an important role in the risk stratification for surveillance decisions.

Abstract
BACKGROUND Lugol chromoendoscopy (LCE) has served as a standard screening technique in high-risk patients with esophageal cancer. Nevertheless, LCE is not suitable for general population screening given its side effects. Linked color imaging (LCI) is a novel image-enhanced endoscopic technique that can distinguish subtle diff-erences in mucosal color.
AIM To compare the diagnostic performance of LCI with LCE in detecting esophageal squamous cell cancer and precancerous lesions and to evaluate whether LCE can be replaced by LCI in detecting esophageal neoplastic lesions.
METHODS In this prospective study, we enrolled 543 patients who underwent white light imaging (WLI), LCI and LCE successively. We compared the sensitivity and specificity of LCI and LCE in the detection of esophageal neoplastic lesions. Clinicopathological features and color analysis of lesions were assessed.
RESULTS In total, 43 patients (45 neoplastic lesions) were analyzed. Among them, 36 patients (38 neoplastic lesions) were diagnosed with LCI, and 39 patients (41 neoplastic lesions) were diagnosed with LCE. The sensitivity of LCI was similar to that of LCE (83.7% vs 90.7%, P = 0.520), whereas the specificity of LCI was greater than that of LCE (92.4% vs 87.0%, P = 0.007). The LCI procedure time in the esophageal examination was significantly shorter than that of LCE [42 (34, 50) s vs 160 (130, 189) s, P < 0.001]. The color difference between the lesion and surrounding mucosa in LCI was significantly greater than that observed with WLI. However, the color difference in LCI was similar in different pathological types of esophageal squamous cell cancer.
CONCLUSION LCI offers greater specificity than LCE in the detection of esophageal squamous cell cancer and precancerous lesions, and LCI represents a promising screening strategy for general populations.

Abstract
Gastric cancer (GC) is the fifth most common cancer worldwide and the third leading cause of cancer death. With the development of single-cell RNA-sequencing (scRNA-seq) technology, the research on GC has gradually developed from the histopathological level to the transcriptional level. In this paper, we discuss the principle of scRNA-seq technology and its application in GC research, including the transcriptional characteristics and origin of GC precancerous lesions, intratumor heterogeneity of primary tumors, tumor microenvironment, and metastatic dissemination.

Abstract
BACKGROUND AND AIMS Treatment strategies for early cancers or precancerous lesions of the upper gastrointestinal tract in cirrhotic patients with esophagogastric varices (EGV) are complicated and risky. We aimed to assess the efficacy and safety of endoscopic submucosal dissection (ESD) in the treatment of such patients and explore optimal treatment strategies. METHODS We retrospectively enrolled 15 cirrhotic patients with EGV who underwent ESD for early cancers or precancerous lesions of the upper gastrointestinal tract from January 2012 to December 2021 at our center. Clinical features, endoscopic findings, treatment methods, adverse events and follow-up data were analyzed. RESULTS Of the 15 patients, 1 had a platelet count <30×1000/mm3. Five were untreated for EGV, 1 was treated after ESD, 6 were treated before ESD, 1 was treated before and during ESD, and 2 were treated during ESD. The R0 resection rate was 100%. Of the 16 mucosal lesions, 15 were ERB-0 or ERB-c1, and 1 was ERB-c2. No patient experienced deterioration in liver function. The only adverse events were fever in 2 patients and postoperative bleeding (PB) in 2 patients. During a median follow-up of 27 months, 1 patient's esophageal HGD recurred at 19 months. No death resulted from the ESD procedure, liver function injury or gastrointestinal tumor itself. CONCLUSION ESD is an effective and safe treatment for early cancers or precancerous lesions of the upper gastrointestinal tract in cirrhotic patients with EGV. The incidence of severe adverse events is very low due to the development of individualized clinical treatment strategies.

Abstract
Early diagnosis and progression assessment are critical for the timely detection and treatment of gastric cancer (GC) patients. Identification of diagnostic biomarkers for early detection of GC represents an unmet clinical need, and how these markers further influence GC progression is explored rarely. We performed dynamic gene screening based on high-throughput data analysis from patients with precancerous lesions and early gastric cancer (EGC) and identified a 10-gene panel by the lasso regression model. This panel demonstrated good diagnostic performance in TCGA (AUC = 0.95, sensitivity = 86.67 %, specificity = 90.63 %) and GEO (AUC = 0.84, sensitivity = 91.67 %, specificity = 78.13 %) cohorts. Moreover, three GC subtypes were clustered based on this panel, in which cluster 2 (C2) demonstrated the highest tumor progression level with a high expression of 10 genes, showing a decreased tumor mutation burden, significantly enriched epithelial-mesenchymal transition hallmark and increased immune exclusion/exhausted features. Finally, the cell localization of these panel genes was explored in scRNA-seq data based on more than 40,000 cells. The 10-gene panel is expected to be a new clinical early detection signature for GC and may aid in progression assessment and personalized treatment of patients.

Abstract
BACKGROUND Although the human papillomavirus (HPV) vaccine has been recommended in Germany for girls since 2007, no organised vaccination programme was introduced and HPV vaccine coverage remains low. We investigated the HPV vaccination rates from 2008 to 2018 and the effects of HPV vaccination on anogenital warts and precancerous lesions in young women in Bavaria, Germany, a state with low vaccination rates. METHODS Retrospective analyses of claims data from the Bavarian Association of Statutory Health Insurance Physicians (KVB) on females born between 1990 and 2009 (9 to 28 years old in 2018) were conducted to calculate vaccination rates by birth cohort, proportion of vaccine types administered and incidence of anogenital warts and precancerous lesions of the cervix uteri. 942 841 Bavarian females 9 to 28 years old with available information on HPV vaccination were included to calculate vaccination rates. For the outcome analyses, data from 433 346 females 19 to 28 years old were analysed. Hazard ratios (HR) were computed from univariable and multivariable Cox regression models comparing vaccinated and unvaccinated women, considering type of vaccine used and contraceptive prescription. RESULTS 40·9% of 18-year-olds and only 13·3% of 12-year-olds were fully vaccinated in 2018 in Bavaria. Gardasil® and Gardasil9® were most commonly administered. Vaccinated compared to unvaccinated women had a lower incidence of anogenital warts and cervical lesions, however only small differences were detected between fully and partially vaccinated women. Fully vaccinated women had a 63% (HR 0·37 (95% confidence interval (CI) 0·34 to 0·40) and 23% (HR 0·77, 95%CI 0·71 to 0·84) lower risk of anogenital warts and cervical lesions, respectively. Women who were prescribed contraceptives prior to vaccination had a 49% higher risk of developing anogenital warts (HR 1·49, 95%CI 1·25 to 1·79) or cervical lesions (HR 1·49, 95%CI 1·27 to 1·75) compared to vaccinated women without contraceptive prescription. CONCLUSIONS The evaluation of the effects of HPV vaccination in Bavaria showed a promising decline of anogenital warts and precancerous lesions in vaccinated young women. However, an increase in vaccination rates is necessary to achieve a greater population impact in preventing HPV-related diseases.

Abstract
BACKGROUND The early screening of cancer has always been the focus of cancer research. As a common cancer in the world, gastric cancer has had a high incidence rate and mortality for many years, and canceration is difficult to detect. Current detection methods are not ideal for early detection of gastric cancer and precancerous lesions.
AIM To assess the value of detection of serum pepsinogen (PG), gastrin (G-17), and hepato-intestinal cadherin-17 (CDH-17) combined with narrowband imaging magnifying endoscopy in the identification of early gastric cancer and precancerous lesions.
METHODS The clinical data of patients with early gastric cancer (106 cases) and precancerous lesions (134 cases) at our hospital from January 2018 to January 2021 were retrospectively analyzed. All patients underwent narrow-band imaging magnifying endoscopy and detection of serum PG (including PGⅠ and PGⅡ), G-17, and CDH-17 levels. The sensitivity, specificity, and accuracy of PG, G-17, CDH-17, and narrow-band imaging magnifying endoscopy, alone and in combination, in the diagnosis of early gastric cancer and precancerous lesions were calculated.
RESULTS In the early gastric cancer group, the incidence of lesions with border limits, mucosal microvascular irregularities, irregular surface ducts, and increased glandular spacing as detected by narrow-band imaging magnifying endoscopy was higher than that in the precancerous lesion group (P < 0.05). The diagnostic coincidence rates of magnifying endoscopy for early gastric cancer and precancerous lesions were 83.02% and 85.07%, respectively, and the difference was not statistically significant (P > 0.05). Serum PGⅠ level in the early gastric cancer group was lower than that of the precancerous lesion group, but there was no significant difference in serum PGⅡ between the two groups (P > 0.05); serum G-17 and CDH-17 levels were higher than those of the precancerous lesion group (P < 0.05). There was no statistically significant difference in the diagnostic coincidence rates of serum PGI, G-17, and CDH-17 alone (P > 0.05). The sensitivity, specificity and accuracy of serum PGⅠ, G-17, and CDH-17 combined with narrow-band imaging magnifying endoscopy in the diagnosis of early gastric cancer and precancerous lesions were higher than those of any serum index alone (PGⅠ/G-17/CDH-17) or narrowband imaging magnifying endoscopy alone (P < 0.05).
CONCLUSION The detection of serum PG, G-17, and CDH-17 combined with narrow-band imaging magnifying endoscopy has high sensitivity, specificity, and accuracy in the differential diagnosis of early gastric cancer and precancerous lesions.

Abstract
BACKGROUND Chronic atrophic gastritis is a common preneoplastic condition of the stomach with a low detection rate during endoscopy. AIMS This study aimed to develop two deep learning models to improve the diagnostic rate. METHODS We collected 10,593 images from 4005 patients including 2280 patients with chronic atrophic gastritis and 1725 patients with chronic non-atrophic gastritis from two tertiary hospitals. Two deep learning models were developed to detect chronic atrophic gastritis using ResNet50. The detection ability of the deep learning model was compared with that of three expert endoscopists. RESULTS In the external test set, the diagnostic accuracy of model 1 for detecting gastric antrum atrophy was 0.890. The identification accuracies for the severity of gastric antrum atrophy were 0.773 and 0.590 in the internal and external test sets, respectively. In the other two external sets, the detection accuracies of model 2 for chronic atrophic gastritis were 0.854 and 0.916, respectively. Deep learning model 1's ability to identify gastric antrum atrophy was comparable to that of human experts. CONCLUSION Deep-learning-based models can detect chronic atrophic gastritis with good performance, which may greatly reduce the burden on endoscopists, relieve patient suffering, and improve the disease's detection rate in primary hospitals.

Abstract
BACKGROUND The occurrence of gastric cancer is a multi-step process involving many factors. Gastrin-17 (G-17), rhomboid domain-containing protein 1 (RHBDD1), and Helicobacter pylori (H. pylori) infection play an important role in the development of gastric cancer and may be used as markers for gastric cancer screening and disease assessment.
AIM To assess the value of serum G-17, RHBDD1, and H. pylori IgG antibody (H. pylori-IgG) in the screening of gastric cancer and precancerous lesions and to analyze their relationship with the depth of tumor infiltration.
METHODS Eighty-five gastric cancer patients treated at our hospital from January 2021 to January 2022 were selected as a study group, and 85 patients with gastric precancerous lesions in the same period were selected as a control group according to the 1:1 matched case-control principle. The general data, serum G-17 and RHBDD1 levels, and H. pylori-IgG positive rate were compared between the two groups. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the value of serum G-17 and RHBDD1 levels and H. pylori-IgG positive rate in diagnosing gastric cancer. Serum G-17 and RHBDD1 levels and H. pylori-IgG positive rate were compared in gastric cancer patients with different tumor infiltration depth, and their correlation with and impact on tumor infiltration depth were analyzed using Spearman's correlation coefficient.
RESULTS Serum G-17 and RHBDD1 levels and H. pylori-IgG positive rate in the study group were significantly higher than those in the control group (P < 0.05). The area under the curve (AUC) of the three indexes combined in the diagnosis of gastric cancer was 0.915. Serum G-17 and RHBDD1 levels and H. pylori-IgG positive rate increased with the increase in the depth of tumor infiltration in gastric cancer patients (P < 0.05), and they were positively correlated with the depth of tumor infiltration (P < 0.05). These three indexes and infiltration depth showed a positive interaction in a sub-phase multiplicative model (P < 0.05).
CONCLUSION Combined detection of serum G-17 and RHBDD1 and H. pylori-IgG antibody can help to improve the screening of gastric cancer and precancerous lesions, and these indexes are involved in and positively correlated with gastric cancer tumor infiltration.

Abstract
Background Current data indicate that supplements such as folic acid and vitamin B may be beneficial in halting and even reversing atrophic gastritis, intestinal metaplasia and intraepithelial neoplasia, generally referred to as gastric precancerous conditions(GPC). However, there is no Meta-analysis article to evaluate the prevention and treatment of folic acid in the gastric precancerous conditions. We therefore conducted a meta-analysis to confirm the efficacy of folic acid in treating GPC. Methods Using a systematic review method, consider randomized controlled trials (RCT), including clinical trial reports, unpublished clinical trial data, and conference papers. The search time was been set from the database’s establishment to June 2, 2021. The language was not limited, using PubMed, SinoMed, Lancet, Web of Science, CNKI, Cochrane, Ovid, Science Direct, Embase, and EBSCO databases. Data were extracted using a pre-designed extraction tool and analysis was undertaken using RevMan5.2.Besides,we use Origin software to construct the Time-dose interval analysis. Results Of the 225 records identified, 13 studies involving 1252 patients (including 11 clinical controlled trials, 1 conference paper report and 1 unpublished research report) met the inclusion conditions. Folic acid dose maintained at 20–30 mg / d for 3–6 months may be beneficial to pathological changes of GPC. Moreover, in the 3 month treatment of 5 trials, the effect was more obvious when the folic acid dose was maintained at 30 mg / d. In the 7 trials, the symptom ineffective rate of GPC treated with folic acid was 32% (RR:0.32, 95% confidence interval CI:0.21–0.48), which was combined using a fixed analysis model; The effect of folic acid on gastric mucosal atrophy in 5 trials (RR: 1.61, 95%CI 1.07–2.41). The changes of folic acid on intestinal metaplasia in the 2 experiments (RR: 1.77, 95% CI: 1.32–2.37).The 2 results are combined using a fixed analytical model. However, the subgroup analysis of 9 trials revealed no significant effectiveness of symptom. Conclusions Our research showed that folic acid supplementation brings benefits in preventing and even reversing the progression of GPC in the stomach, and provided evidence for its potential clinical use in management of GPC. Registration: The logn number of our Meta-anlysis on PROSPERO is CRD420223062. Supplementary Information The online version contains supplementary material available at 10.1186/s12876-022-02390-y.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infects about 50% of the world population and is the major cause of chronic gastritis, peptic ulcers, and gastric cancer. Chronic H. pylori infection induces gastric mucosal precancerous lesions mostly in adulthood, and it is debatable whether these pathological conditions can occur in childhood and adolescents as well. Since this is a critical issue to determine if intervention should be offered for this population group, we investigated the gastric mucosal precancerous lesions in pediatric patients in an area in central China with a high prevalence of H. pylori and gastric cancer.
AIM To investigate the relationship of H. pylori infection and gastric mucosal precancerous lesions in children and adolescents in central China.
METHODS We screened 4258 ward-admitted children and adolescent patients with upper gastrointestinal symptoms, and finally enrolled 1015 pediatric patients with H. pylori infection and endoscopic and histological data. H. pylori infection status was determined by rapid urease test and histopathological examination. Both clinical and pathological data were collected and analyzed retrospectively. Occurrence of gastric mucosal precancerous lesions, inflammatory activity and degree of inflammatory cell infiltration between H. pylori-positive and -negative groups were compared.
RESULTS Among the 1015 eligible children and adolescents, the overall H. pylori infection rate was 84.14% (854/1015). The infection rate increased with age. The incidence of gastric mucosal precancerous lesions in H. pylori-infected children was 4.33% (37/854), which included atrophic gastritis (17 cases), intestinal metaplasia (11 cases) and dysplasia (9 cases). In H. pylori-negative patients, only 1 atrophic gastritis case [0.62%, (1/161)] was found (P < 0.05). Active inflammation in H. pylori-infected patients was significantly higher than that in non-infected patients, and the H. pylori-infected group showed more severe lymphocyte and neutrophil granulocyte infiltration (P < 0.001). In addition, endoscopy revealed that the most common findings in H. pylori-positive patients were antral nodularity, but in H. pylori-negative patients only superficial gastritis was observed.
CONCLUSION In children and adolescents, gastric mucosal precancerous lesions occurred in 4.33% of H. pylori-infected patients in central China. These cases included atrophic gastritis, intestinal metaplasia, and dysplasia. The data revealed an obvious critical issue requiring future investigation and intervention for this population group.

Abstract
BACKGROUND Endoscopic treatment is the first choice for early esophageal lesions without obvious metastasis or infiltration, especially endoscopic submucosal dissection (ESD). However, the occurrence of non-curative resection, recurrence, or metastasis after ESD is inevitable, which may require adjuvant therapy such as additional surgery or chemora-diotherapy.
AIM To analyze the risk factors for additional surgery or chemora-diotherapy after ESD for early esophageal lesions, and explore the effect of curative resection on additional adjuvant therapy.
METHODS Patients who underwent ESD for stage T1 esophageal cancer (EC) and precancerous lesions were analyzed retrospectively. Postoperative recurrence, metastasis, and adjuvant treatment were followed, and a prediction model for adjuvant treatment population selection was established.
RESULTS Non-curative resection was correlated with patient age, proportion of lesions, and microscopic size(P < 0.05), among which the proportion of lesions > 2/3 (odds ratio [OR] = 7.958, P = 0.007) was an independent risk factor. Two of curative and ten of non-curative resection cases received additional treatment, indicating that further treatment after ESD might be required regardless of whether curative resection was performed. Patient age, proportion of lesions, lesion lifting, differentiation, vascular invasion, and tumor invasion depth were correlated with the need for further treatment (P < 0.05). Age ≥ 70 years (OR = 4.210, P = 0.049), poor lifting (OR = 18.171, P = 0.047), and depth of tumor up to SM2 (OR = 38.781, P = 0.012) were independent risk factors. The AUC of the nomogram model was 0.864 (95%CI: 0.766-0.962); the specificity and sensitivity were 95.8% and 75.0%, respectively. Calibration curve analysis, decision curve analysis, and Hosmer and Lemeshow test (χ2 = 1.5954, P = 0.991) showed that the predictive value of the model was acceptable.
CONCLUSION For patients with stage T1 EC and precancerous lesions, whether further surgery or chemoradiotherapy is needed after ESD should be comprehensively considered.

Abstract
Cytology identifies the women who are at higher risk of harboring high-grade cervical premalignant lesions or invasive cancer. However, a diagnostic test such as colposcopy is crucial for women with abnormal cytology for localization of the abnormality, confirmation of diagnosis, and appropriate management. To standardize this subjective technique and to minimize the interobserver variations, Swede scoring system was introduced. The revised colposcopic nomenclature of the International Federation of Cervical Pathology and Colposcopy in 2011 included various normal and abnormal colposcopic findings and gives a description of colposcopic features which improves its accuracy over the colposcopic indices. There is consensus agreement that cytology indicative of high-grade lesions (ASC-H and HSIL in the Bethesda system) should engender immediate referral for colposcopy and biopsy. The management of women who have equivocal or borderline cytology of low-grade abnormalities (ASCUS/LSIL) is still under deliberation. It is generally agreed to have an HPV triage for women with equivocal cytology. Based on the latest recommendations, the current chapter provides an extensive overview of the role of colposcopy in the management of women with various abnormalities reported on Pap smear.

Abstract
Objective: To construct the diagnostic model of superficial esophageal squamous cell carcinoma (ESCC) and precancerous lesions in endoscopic images based on the YOLOv5l model by using deep learning method of artificial intelligence to improve the diagnosis of early ESCC and precancerous lesions under endoscopy. Methods: 13, 009 endoscopic esophageal images of white light imaging (WLI), narrow band imaging (NBI) and lugol chromoendoscopy (LCE) were collected from June 2019 to July 2021 from 1, 126 patients at the Cancer Hospital, Chinese Academy of Medical Sciences, including low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia, ESCC limited to the mucosal layer, benign esophageal lesions and normal esophagus. By computerized random function method, the images were divided into a training set (11, 547 images from 1, 025 patients) and a validation set (1, 462 images from 101 patients). The YOLOv5l model was trained and constructed with the training set, and the model was validated with the validation set, while the validation set was diagnosed by two senior and two junior endoscopists, respectively, to compare the diagnostic results of YOLOv5l model and those of the endoscopists. Results: In the validation set, the accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the YOLOv5l model in diagnosing early ESCC and precancerous lesions in the WLI, NBI and LCE modes were 96.9%, 87.9%, 98.3%, 88.8%, 98.1%, and 98.6%, 89.3%, 99.5%, 94.4%, 98.2%, and 93.0%, 77.5%, 98.0%, 92.6%, 93.1%, respectively. The accuracy in the NBI model was higher than that in the WLI model (P<0.05) and lower than that in the LCE model (P<0.05). The diagnostic accuracies of YOLOv5l model in the WLI, NBI and LCE modes for the early ESCC and precancerous lesions were similar to those of the 2 senior endoscopists (96.9%, 98.8%, 94.3%, and 97.5%, 99.6%, 91.9%, respectively; P>0.05), but significantly higher than those of the 2 junior endoscopists (84.7%, 92.9%, 81.6% and 88.3%, 91.9%, 81.2%, respectively; P<0.05). Conclusion: The constructed YOLOv5l model has high accuracy in diagnosing early ESCC and precancerous lesions in endoscopic WLI, NBI and LCE modes, which can assist junior endoscopists to improve diagnosis and reduce missed diagnoses.

Abstract
BACKGROUND C20orf54 has been identified as an esophageal squamous cell carcinoma (ESCC) susceptibility gene in previous genome-wide association studies. Here, we attempted to clarify the expression level of C20orf54 in ESCC, non-tumoral esophageal tissues, and esophageal squamous intraepithelial neoplasia (ESIN). METHODS We assessed C20orf54 expression in 146 ESCC, 108 non-tumoral esophageal tissues, and 148 ESIN using immunohistochemistry on tissue microarrays. We also evaluated the possible correlations of C20orf54 expression with clinicopathological characteristics. The survival rates were analyzed using the Kaplan-Meier method and log-rank test. RESULTS C20orf54 expression was significantly lower in ESCC, high-grade ESIN, and low-grade ESIN than in the non-tumoral esophageal tissues. The level observed for ESCC was also significantly lower than that in low-grade ESIN and high-grade ESIN, whereas no difference was observed between high-grade ESIN and low-grade ESIN. Furthermore, the C20orf54 defective expression correlated significantly with differentiation, lymph node metastasis, and invasion depth. The overall survival time was inversely associated with lymph node metastasis, an advanced TNM stage (III + IV), and deeper invasion. CONCLUSIONS This study provides the first evidence of C20orf54 defective expression in ESCC and precancerous lesions, demonstrating a potential role in tumor progression and metastasis. C20orf54 could be used as a potential biomarker for the early detection of ESCC.

Abstract
BACKGROUND Screening for gastric cancer is an effective method for early diagnosis of gastric cancer. Studies at home and abroad have found significant differences in serum gastrin-17, pepsinogen Ⅰ, Ⅱ and Helicobacter pylori (H. pylori) IgG (Hp-IgG) antibody levels between patients with gastric cancer and precancerous lesions. It is speculated that screening can be used in the diagnosis and evaluation of gastric cancer.
AIM To explore the screening of gastric cancer and precancerous lesions by serum gastrin-17 (G-17), pepsinogen (PG) I, PG II, Hp-IgG antibody levels value and its relationship with the depth of tumor invasion.
METHODS From August 2019 to March 2021, 90 patients with gastric cancer in our hospital were selected as the research group, 90 patients with gastric precancerous lesions during the same period were selected as the control group A, and 90 healthy subjects were selected as the control group B. Compare 3 groups of general information, serum G-17, PG Ⅰ, PG Ⅱ levels, Hp-IgG positive rate, compare serum G-17, PG Ⅰ, PG Ⅱ levels of Hp-IgG positive and negative patients, and analyze serum G-17, PG Ⅰ, PG Ⅱ The relationship between the level and Hp-IgG positive, analyze the value of each index in the diagnosis of gastric cancer and the relationship with the depth of gastric cancer tumor invasion.
RESULTS Serum G-17, PGII levels and Hp-IgG positive rate in the study group were all > control group A > control group B, serum PG Ⅰ level < control group A < control group B (P < 0.05); the serum G-17 and PGⅡ levels of Hp-IgG positive patients in the study group Both were higher than in negative patients, and serum PG Ⅰ levels were lower than in negative patients (P < 0.05); serum G-17 and PG Ⅱ levels were positively correlated with Hp-IgG positive, and serum PG Ⅰ was negatively correlated with Hp-IgG positive (P < 0.05); The area under curve (AUC) of serum G-17, PG Ⅰ, PG Ⅱ, and Hp-IgG positive diagnosis of gastric cancer were 0.828, 0.845, 0.821, 0.650, respectively. The combined diagnosis of each index had the largest AUC, which was 0.887. The best diagnostic sensitivity and specificity The levels were 80.03% and 84.46%, respectively; serum G-17, PG Ⅱ levels, and Hp-IgG positive rates gradually increased with the increase of gastric cancer tumor invasion depth, and serum PG Ⅰ levels gradually decreased with the increase of gastric cancer tumor invasion depth (P < 0.05); The depth of gastric cancer tumor invasion was positively correlated with serum G-17, PG Ⅱ, Hp-IgG positive, and negatively correlated with serum PG Ⅰ (P < 0.05).
CONCLUSION Serum levels of G-17, PG Ⅰ, PG Ⅱ, and Hp-IgG have certain diagnostic value in the screening of gastric cancer and precancerous lesions, and are closely related to the depth of gastric cancer tumor invasion.

Abstract
Background Cervical cancer (CC) is the fourth most common cancer among women worldwide and Malawi has the world’s highest rate of cervical cancer related mortality. Since 2016 the National CC Control Strategy has set a screening coverage target at 80% of 25-49-year-old women. The Ministry of Health and Médecins Sans Frontières (MSF) set up a CC program in Blantyre City, as a model for urban areas, and Chiradzulu District, as a model for rural areas. This population-based survey aimed to estimate CC screening coverage and to understand why women were or were not screened. Methods A population-based survey was conducted in 2019. All resident consenting eligible women aged 25-49 years were interviewed (n = 1850) at households selected by two-stage cluster sampling. Screening and treatment coverage and facilitators and barriers to screening were calculated stratified by age, weighted for survey design. Chi square and design-based F tests were used to assess relationship between participant characteristics and screening status. Results The percentage of women ever screened for CC was highest in Blantyre at 40.2% (95% CI 35.1-45.5), 38.9% (95% CI 32.8-45.4) in Chiradzulu with supported CC screening services, and lowest in Chiradzulu without supported CC screening services at 25.4% (95% CI 19.9-31.8). Among 623 women screened, 49.9% (95% CI 44.0-55.7) reported that recommendation in the health facility was the main reason they were screened and 98.5% (95% CI 96.3-99.4) recommended CC screening to others. Among 1227 women not screened, main barriers were lack of time (26.0%, 95% CI 21.9-30.6), and lack of motivation (18.3%, 95% CI 14.1-23.3). Overall, 95.6% (95% CI 93.6-97.0) of women reported that they had some knowledge about CC. Knowledge of CC symptoms was low at 34.4% (95% CI 31.0-37.9) and 55.1% (95% CI 51.0-59.1) of participants believed themselves to be at risk of CC. Conclusion Most of the survey population had heard about CC. Despite this knowledge, fewer than half of eligible women had been screened for CC. Reasons given for not attending screening can be addressed by programs. To significantly reduce mortality due to CC in Malawi requires a comprehensive health strategy that focuses on prevention, screening and treatment.

Abstract
Background Despite research efforts, the causative factors that contribute to esophageal squamous cell carcinoma (ESCC) in high-risk areas have not yet been understood. In this study, we, therefore, aimed to describe the risk factors associated with ESCC and its precursor lesions. Methods We performed an endoscopic examination of 44,857 individuals aged 40–69 years from five high incidence regions of China in 2017–2018. Participants were classified as 4 groups of normal control, esophagitis, low-grade intraepithelial neoplasia (LGIN) and high-grade intraepithelial neoplasia/esophageal squamous cell carcinoma (HGIN/ESCC) using an unconditional logistic regression determine risk factors. Results We identified 4890 esophagitis, 1874 LGIN and 437 HGIN/ESCC cases. Crude odds ratios (ORs) and adjusted odds ratios were calculated using unconditional logistic regression. Drinking well and surface water, salty diet, and positive family history of cancer were the common risk factors for esophagitis, LGIN and HGIN/ESCC. History of chronic hepatitis/cirrhosis was the greatest risk factor of esophagitis (adjusted OR 2.96, 95%CI 2.52–3.47) and HGIN/ESCC (adjusted OR 1.91, 95%CI 1.03–3.22). Pesticide exposure (adjusted OR 1.20, 95%CI 1.05–1.37) was essential risk factor of LGIN. Conclusions Among individuals aged 40–69 years in high incidence regions of upper gastrointestinal cancer, the results provided important epidemiological evidence for the prevention of different precancerous lesions of ESCC.

Abstract
OBJECTIVE We aim to evaluate the diagnostic value of autofluorescence laryngoscope (AFL) in early laryngeal carcinoma and precancerous lesions. aWe also assess the value of AFL in diagnosis of early laryngeal carcinoma and precancerous lesions in comparison with that of white light laryngoscope (WL). METHODS The databases consisting of PubMed, Cochrane Library, Web of science and CNKI were systematically searched to find pertinent literatures of AFL in diagnosing early laryngeal carcinoma and precancerous lesions. We made a quality evaluation of every study we included using the modified Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). The pooled sensitivities, specificities were calculated using Meta-Disc 1.4. And we estimated the summary receiver operating characteristic curves (SROC) and area under the curves (AUC). RESULTS We finally included 23 studies. The results of AFL in diagnosing early laryngeal carcinoma and precancerous lesions showed higher sensitivity of 0.91 (95%CI: 0.89-0.93; χ²=43.78, p = 0.0025) and specificity of 0.80 (95%CI: 0.77-0.82; χ²=130.64, p = 0.000), and the weighted AUC of AFL was 0.948 ± 0.013 (95%CI: 0.921-0.974) and the diagnostic accuracy (Q*) was 0.887 ± 0.018. The sensitivity and specificity of WL were 0.74 (95%CI: 0.70-0.77; χ²=52.40, p = 0.000) and 0.89 (95%CI: 0.87-0.90; χ²=299.22, p = 0.000), and the weighted AUC of WL was 0.835 ± 0.029 (95%CI: 0.777-0.892) and the diagnostic accuracy (Q*) was 0.767 ± 0.027. CONCLUSION The meta-analysis and systematic review suggested that AFL had high diagnostic value in early laryngeal carcinoma and precancerous lesions, and its diagnostic value was higher than that of WL. These results indicated that AFL can provide good guidance for the early detection of laryngeal carcinoma and precancerous lesions.

Abstract
Gastric xanthelasma has always been considered a benign lesion of the stomach. It is formed by tissue cells or macrophages phagocytizing a large amount of lipid and accumulating in the lamina propria. However, recent studies have found that gastric xanthelasma is associated with precancerous lesions and gastric cancer, and should be differentiated from signet ring cell carcinoma and clear cell carcinoma of the stomach.

Abstract
Upper gastrointestinal (GI) cancers are the leading cause of cancer-related deaths worldwide. Early identification of precancerous lesions has been shown to minimize the incidence of GI cancers and substantiate the vital role of screening endoscopy. However, unlike GI cancers, precancerous lesions in the upper GI tract can be subtle and difficult to detect. Artificial intelligence techniques, especially deep learning algorithms with convolutional neural networks, might help endoscopists identify the precancerous lesions and reduce interobserver variability. In this review, a systematic literature search was undertaken of the Web of Science, PubMed, Cochrane Library and Embase, with an emphasis on the deep learning-based diagnosis of precancerous lesions in the upper GI tract. The status of deep learning algorithms in upper GI precancerous lesions has been systematically summarized. The challenges and recommendations targeting this field are comprehensively analyzed for future research.

Abstract
Human papillomaviruses (HPVs) can cause both benign and malignant tumors. To date, more than 200 HPV types have been discovered, of which 12 are currently classified as high risk for cervical cancer. HPV types that affect the anogenital tract are sexually transmitted. Since 2006, prophylactic HPV vaccines have been available and should be administered before first sexual contact.HPVs infect epithelial cells and are worldwide the most common sexually transmitted viruses. Apart from cervical cancer, HPVs cause other anogenital cancers such as vulvar, vaginal, and anal cancer but also oropharyngeal cancer (or head and neck cancers). HPV types 16 and 18 are also found at these sites. HPV types 6 and 11 are associated with genital warts; other HPV types can cause harmless skin warts.HPV vaccines are safe and highly effective, if they are administered before exposure to HPV. Systematic reviews and meta-analyses have shown that HPV vaccination effectively prevents HPV infection, but also precancerous lesions of the anogenital tract and genital warts. Recent vaccination data also demonstrate reductions in cervical cancer incidence.The uptake rates of HPV vaccination vary worldwide by program and acceptance. In comparison to other European countries, Germany has a low uptake rate. The Standing Committee on Vaccination (STIKO) recommends HPV vaccinations for all girls and boys ages 9 to 14 years in Germany. In 2018, only half of all 18-year-old girls in Germany were completely immunized against HPV.Organized vaccination programs, whether population-based or school-based, are necessary in order to increase vaccination uptake rates.

Abstract
Background Confocal laser endomicroscopy (CLE) has advantages in detecting gastric neoplastic lesions, meanwhile it requires strict patient cooperation. Sedation could improve patient cooperation and quality of endoscopy. However, sedation is still not very popular in some resource-limited countries and regions. The purpose of this study was to compare propofol-based sedated versus un-sedated CLE in the value of diagnosing early gastric cancer (EGC) and precancerous lesions. Methods A retrospective, cohort, single center study of 226 patients who underwent CLE between January 1, 2015 and December 31, 2017 was performed. Patients enrolled were allocated into the propofol-based sedated group (n = 126) and the un-sedated group (n = 100). The comparison of validity and reliability of CLE for identifying EGC and precancerous lesions between the two groups was performed through analyzing CLE diagnosis and pathological diagnosis. Reporting followed the STROBE guidelines. Results The area under receiver operating characteristic curve (AUROC) of diagnosing EGC in the sedated group was 0.97 (95 % CI: 0.95 to 0.99), which was higher than that in the un-sedated group (0.88 (95 % CI: 0.80 to 0.97), P = 0.0407). CLE with sedation performed better than without sedation in diagnosing intraepithelial neoplasia and intestinal metaplasia (P = 0.0008 and P = 0.0001, respectively). For patients considered as high-grade intraepithelial neoplasia or EGC by endoscopists, they would not get biopsy during CLE but receive endoscopic submucosal dissection (ESD) subsequently, and the misdiagnosis rate of CLE was 0 % in the sedated group and 27.59 % (95 % CI: 10.30–44.91 %) in the un-sedated group (P = 0.006). Conclusions Propofol based sedation was associated with improved diagnostic value of CLE for detecting EGC as well as precancerous lesions (intraepithelial neoplasia OR intestinal metaplasia).

Abstract
BACKGROUND In recent years, two new narrow-band imaging (NBI) classifications have been proposed: The NBI international colorectal endoscopic (NICE) classification and Japanese NBI expert team (JNET) classification. Most validation studies of the two new NBI classifications were conducted in classification setting units by experienced endoscopists, and the application of use in different centers among endoscopists with different endoscopy skills remains unknown.
AIM To evaluate clinical application and possible problems of NICE and JNET classification for the differential diagnosis of colorectal cancer and precancerous lesions.
METHODS Six endoscopists with varying levels of experience participated in this study. Eighty-seven consecutive patients with a total of 125 lesions were photographed during non-magnifying conventional white-light colonoscopy, non-magnifying NBI, and magnifying NBI. The three groups of endoscopic pictures of each lesion were evaluated by the six endoscopists in randomized order using the NICE and JENT classifications separately. Then we calculated the six endoscopists’ sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for each category of the two classifications.
RESULTS The sensitivity, specificity, and accuracy of JNET classification type 1 and 3 were similar to NICE classification type 1 and 3 in both the highly experienced endoscopist (HEE) and less-experienced endoscopist (LEE) groups. The specificity of JNET classification type 1 and 3 and NICE classification type 3 in both the HEE and LEE groups was > 95%, and the overall interobserver agreement was good in both groups. The sensitivity of NICE classification type 3 lesions for diagnosis of SM-d carcinoma in the HEE group was significantly superior to that in the LEE group (91.7% vs 83.3%; P = 0.042). The sensitivity of JNET classification type 2B lesions for the diagnosis of high-grade dysplasia or superficial submucosal invasive carcinoma in the HEE and LEE groups was 53.8% and 51.3%, respectively. Compared with other types of JNET classification, the diagnostic ability of type 2B was the weakest.
CONCLUSION The treatment strategy of the two classification type 1 and 3 lesions can be based on the results of endoscopic examination. JNET type 2B lesions need further examination.

Abstract
Interest in the use of cell-free nucleic acids (CFNAs) as clinical non-invasive biomarker panels for prediction and prevention of multiple diseases has greatly increased over the last decade. Indeed, circulating CFNAs are attributable to many physiological and pathological processes such as imbalanced stress conditions, physical activities, extensive apoptosis of different origin, systemic hypoxic-ischemic events and tumour progression, amongst others. This article highlights the involvement of circulating CFNAs in local and systemic processes dealing with the question, whether specific patterns of CFNAs in blood, their detection, quantity and quality (such as their methylation status) might be instrumental to predict a disease development/progression and could be further utilised for accompanying diagnostics, targeted prevention, creation of individualised therapy algorithms, therapy monitoring and prognosis. Presented considerations conform with principles of 3P medicine and serve for improving individual outcomes and cost efficacy of medical services provided to the population.

Abstract
With the development of multi-omics and high throughput sequencing technology, studies have shown that the disorder of microbiota is related to various cancers. Nevertheless, the research on the relationship between upper digestive tract cancer or precancerous lesions and gastrointestinal microecology is still less. Fusobacterium nucleatum, one of the oral symbiotic bacteria, is also an opportunistic pathogen, which can promote the formation of tumor microenvironment and can be used as a new biomarker for the early detection and early diagnosis of cancer. In this study, by searching CNKI, Wanfang data, PubMed and Embase databases, it was found that the abundance of F. nucleatum in cancer tissues is higher than that in paracancerous tissues and associated with poor prognosis. The research of relationship between F. nucleatum and precancerous lesions needs to be carried out urgently. In addition, the types of specimens, sequencing technology, strain subtypes, carcinogenic mechanism and other directions still need to be explored.

Abstract
INTRODUCTION The purpose of this study was to conduct a retrospective study about the clinical effects of endoscopic mucosal dissection on the treatment of early esophagogastric precancerous lesions. METHODS A total of 132 patients with early esophagogastric precancerous lesions who were diagnosed and treated with concurrent surgery in our hospital from January 2018 to December 2019 were included in this retrospective study. Patients were divided into endoscopic mucosal resection (EMR) group (n = 58) and endoscopic submucosal dissection (ESD) group (n = 74) according to different surgical methods. The data in the two groups were compared and analyzed in terms of surgical indicators, treatment status and incidence of postoperative complications. RESULTS There were statistically significant differences between the two groups in the whole block cutting rate, fractional cutting rate and complete cutting rate (P < 0.05). The mean operation time of ESD group was significantly longer than that of EMR group (P < 0.05). There were no significant differences in the intraoperative bleeding rate, blood loss, average specimen area, length of hospital stay and treatment cost between the two groups (P > 0.05). The incidence and recurrence of postoperative complications, including bleeding, perforation and stenosis in the two groups, were observed within 1 year of postoperative follow-up. The incidence of complications in ESD group was slightly higher than that in EMR group, and the local recurrence rate in ESD group was lower than that in EMR group (P > 0.05). CONCLUSION ESD is an alternative surgical treatment for patients with early esophagogastric precancerous lesions.

Abstract
Background Radiofrequency ablation (RFA) is an effective treatment for dysplastic Barrett's esophagus (BE), but recurrence can occur after initial response. Currently there is uncertainty about how to best define histological remission. A DNA methylation panel on esophageal samples was previously shown to have high diagnostic accuracy for BE. We aimed to investigate this biomarker panel in the assessment of response to RFA treatment. Methods We retrospectively analyzed esophageal and gastroesophageal junction (GEJ) biopsies from patients with BE before and after RFA treatment. We quantified the extent of intestinal metaplasia (IM) based on number of glands with goblet cells (IM-Score) and expression of the intestinal factor trefoil factor-3 (TFF3-Score). Promoter methylation of 3 genes (ZNF345, TFP12, ZNF569) was measured by methylight (Meth-Score) throughout the RFA treatment pathway. Findings We included 45 patients (11 non-dysplastic BE, 14 low-grade dysplasia, 20 high-grade dysplasia/intramucosal cancer). Meth-Scores were significantly higher in BE with and without dysplasia and GEJ with IM compared to GEJ without IM (P<·001). Meth-scores significantly correlated with the extent of IM at the GEJ measured both with IM-Scores (rho=66·0%, P<·001), and TFF3-Scores (rho=75·6%, P<·001). In patients with residual IM at the GEJ, RFA re-treatment brought about a 7·6-fold reduction in the methylation levels. The Meth-score had an area under the ROC curve of 95·1% (95%CI 91·1% - 99·1%) differentiating BE from normal GEJ. Interpretation A DNA methylation panel can discriminate between the extent of histological IM in esophageal and junctional biopsies and could be used to objectively quantify residual disease following RFA.

Abstract
BACKGROUND Photodynamic therapy (PDT) is a minimally invasive method for the treatment of oral leukoplakia (OL) through the activation of a photosensitizer, after exposure to a specific wavelength light source. METHODS To investigate the effectiveness of toluidine blue as topical photosensitizer. Eleven patients participated in this study; fifteen oral leukoplakia lesions were treated, in several sessions, with 2.5 % toluidine blue and an LED source of 630 nm wavelength. Patients were evaluated at baseline (t0), at the end of treatment cycles (t1) and one year from the end of treatment (t2). All the treated sites were photographed at each visit. Images were processed with ImageJ 1.52 software in order to obtain the areas (mm2) of the treated lesions. Comparison between data at different follow-up was performed using a paired T-test. RESULTS At t1, complete response was obtained in six lesions, partial response in seven lesions while only two lesions showed no response. At t2, a further improvement was observed in two patients. The analysis of the areas showed significant reduction of the lesion size from t0 to t1 (p = 0.003), and from t1 to t2 (p = 0.01). CONCLUSION Toluidine blue appears to be a promising photosensitizer in the photodynamic therapy of oral leukoplakia.

Abstract
BACKGROUND Pancreatic cancer is one of the most lethal diseases with an incidence almost equal to the mortality. In addition to having genetic causes, cancer can also be considered an epigenetic disease. DNA methylation is the premier epigenetic modification and patterns of aberrant DNA methylation are recognized to be a common hallmark of human tumor. In the multistage carcinogenesis of pancreas starting from precancerous lesions to pancreatic ductal adenocarcinoma (PDAC), the epigenetic changes play a significant role. DATA SOURCES Relevant studies for this review were derived via an extensive literature search in PubMed via using various keywords such as pancreatic ductal adenocarcinoma, precancerous lesions, methylation profile, epigenetic biomarkers that are relevant directly or closely associated with the concerned area of our interest. The literature search was intensively done considering a time frame of 20 years (1998-2018). RESULT In this review we have highlighted the hypermethylation and hypomethylation of the precancerous PDAC lesions (pancreatic intra-epithelial neoplasia, intraductal papillary mucinous neoplasm, mucinous cystic neoplasm and chronic pancreatitis) and PDAC along with the potential biomarkers. We have also achieved the early epigenetic driver that leads to progression from precancerous lesions to PDAC. A bunch of epigenetic driver genes leads to progression of precancerous lesions to PDAC (ppENK, APC, p14/5/16/17, hMLH1 and MGMT) are also documented. We summarized the importance of these observations in therapeutics and diagnosis of PDAC hence identifying the potential use of epigenetic biomarkers in epigenetic targeted therapy. Epigenetic inactivation occurs by hypermethylation of CpG islands in the promoter regions of tumor suppressor genes. We listed all hyper- and hypomethylation of CpG islands of several genes in PDAC including its precancerous lesions. CONCLUSIONS The concept of the review would help to understand their biological effects, and to determine whether they may be successfully combined with other epigenetic drugs. However, we need to continue our research to develop more specific DNA-demethylating agents, which are the targets for hypermethylated CpG methylation sites.

Abstract
BACKGROUND This study aimed to analyze the risk factors for complications after endoscopic treatment of early esophageal cancer and precancerous lesions and provides evidence for developing preventive measures against these complications. METHODS The clinical data of patients with early esophageal cancer and precancerous lesions treated in the Department of Endoscopy, National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, and Peking Union Medical College from January 2009 to December 2015 were analyzed. The risk factors related to delayed bleeding, perforation, and stenosis were assessed. RESULTS Of 459 patients, 15 (3.3%) had delayed bleeding, 16 (3.5%) had perforation, and 82 (17.9%) had stenosis. Conservative treatment was performed for patients with bleeding and perforation, and endoscopic dilation was performed to relieve stenosis. The independent risk factors for delayed bleeding were lesion size (OR = 1.51, P = 0.020), circumferential diameter [odds ratio (OR) = 1.24, P = 0.037]. The kind of operation method [endoscopic submucosal dissection (ESD)/cap-based endoscopic resection (EMR-Cap): OR = 15.38, P = 0.013) was the independent risk factor for perforation. The independent predictors of stenosis were circumferential diameter (OR = 1.58, P < 0.001), lesion in the neck (OR = 0.12, P = 0.003), and surgical time (OR = 1.02, P = 0.007). CONCLUSION Few complications occur after the endoscopic treatment of early esophageal cancer and precancerous lesions which can be treated by endoscopic and conservative medical therapies. Strict operational training is required for ESD treatment.

Abstract
Endothelin-1 (ET-1) and its two receptors, endothelin receptor A (ETAR) and endothelin receptor B (ETBR) exhibit deregulated overexprerssion in pancreatic ductal adenocarcinoma (PDAC) and pancreatitis. We examined the expression pattern of endothelin (ET) axis components in the murine models of chronic and acute inflammation in the presence or absence of oncogenic K-ras. While the expression of endothelin converting enzyme-1 (ECE-1), ET-1, ETAR and ETBR in the normal pancreas is restricted predominantly to the islet cells, progressive increase of ET receptors in ductal cells and stromal compartment is observed in the KC model (Pdx-1 Cre; K-rasG12D) of PDAC. In the murine pancreas harboring K-rasG12D mutation (KC mice), following acute inflammation induced by cerulein, increased ETAR and ETBR expression is observed in the amylase and CK19 double positive cells that represent cells undergoing pancreatic acinar to ductal metaplasia (ADM). As compared to the wild type (WT) mice, cerulein treatment in KC mice resulted in significantly higher levels of ECE-1, ET-1, ETAR and ETBR, transcripts in the pancreas. Similarly, in response to cigarette smoke-induced chronic inflammation, the expression of ET axis components is significantly upregulated in the pancreas of KC mice as compared to the WT mice. In addition to the expression in the precursor pancreatic intraepithelial neoplasm (PanIN lesions) in cigarette smoke-exposure model and metaplastic ducts in cerulein-treatment model, ETAR and ETBR expression is also observed in infiltrating F4/80 positive macrophages and α-SMA positive fibroblasts and high co-localization was seen in the presence of oncogenic K-ras. In conclusion, both chronic and acute pancreatic inflammation in the presence of oncogenic K-ras contribute to sustained upregulation of ET axis components in the ductal and stromal cells suggesting a potential role of ET axis in the initiation and progression of PDAC.

Abstract
Hepatocarcinogenesis is a multi-step process in which detection of precancerous lesions and advanced hepatocellular carcinoma in its progressive stage is crucially important for predicting tumor behavior, estimating the extent of lesions, implementing the optimal treatment strategy, and improving the survival of patients. The rapid development and wide application of liver imaging technology, especially the application of hepatocyte-specific gadoxetate disodium MRI contrast agent (Gd-EOB-DTPA MRI), not only provide information on vascular changes of liver nodules and hepatocyte function, but also has become a precise diagnostic method for differentiating cirrhotic regenerative nodule (RN), low-grade dysplastic nodule (LGDN), high-grade dysplastic nodule (HGDN), early hepatocellular carcinoma and HCC. Hence, the risk for malignant progression is stratified. This review summarizes the value of Gd-EOB-DTPA MRI for early HCC diagnosis and analyzes the key concepts in the multi-step process of HCC development as well as the imaging manifestations of precancerous lesions that may eventually be transformed into typical HCC.

Abstract
Objective: To explore the screening efficiency of colorectal cancer in urban residents of Kunming, China. Methods: Using the method of cluster sampling, from October 2014 to October 2017, residents of the three jurisdictions of Xishan, Guandu and Chenggong Districts of Kunming city were investigated. The inclusion criteria: (1) resident (for more than 3 years) population of Kunming city aged 40-74 years old; (2) voluntarily participating and receiving colonoscopy; (3) signing informed consent. Based on the Harvard Cancer Risk Index, the questionnaire was built on the consensus of more than 20 years of common cancer epidemiology in China. Through the consensus reached by the multidisciplinary expert panel discussion, a comprehensive evaluation system for cancer risk in China was designed. The high-risk group of colorectal cancer was determined by preliminary screening of the questionnaire, and a free colonoscopy was performed for the appointment to the gastrointestinal endoscopy department of the Yunnan Cancer Hospital. All polypoid lesions and ulcers found by colonoscopy must be biopsied to confirm the diagnosis. χ(2) test or Fisher exact probability method was used to compare the detection of colorectal cancer in 4 groups of 40-49 years old, 50-59 years old, 60-69 years old, and ≥70-years old. Detection of colonoscopy, compliance, pathological examination, pathological diagnosis, and morbidity of colorectal cancer were analyzed. Results: A total of 127 960 people from 40 to 74 years old of urban residents in Kunming city participated in the preliminary screening of the questionnaire, including 59 748 (46.7%) males and 68 212 females (53.3%) with mean age of (53.6±8.6) years old. The 40-49 years old group had the largest number of participants (48 044, 37.5%), followed by the groups of 50-59 years old (42 473, 33.2%), 60-69 years old (34 111, 26.7%), and ≥70 years old (3332, 2.6%). Till October 2017, a total of 14 971 people were screened as at high risk of colorectal cancer, with the high-risk detection rate of 11.7%, and the high-risk detection rate of women was significantly higher than that of men [13.4% (9 109/68 212) vs. 9.8% (5 862/59 748), χ(2)=386.947, P<0.001]. The highest high-risk detection rate was in the 50-59 years group in both gender [men: 11.1% (2202/19 831), women: 15.3% (3034/22 642)]. A total of 3449 people among the high-risk population received colonoscopy examination. The compliance rate of colonoscopy was 23.0% (3449/14 971), and the male compliance rate was 19.8% (1162/5862), which was significantly lower than that of females [25.1% (2287/9109), χ(2)=56.175, P<0.001]. The highest compliance was observed in the 50-59 years group [25.4% (1438/5668)], followed by 40-49 years and 60-69 year group [22.1%(1091/4931) and 22.0%(891/4048), respectively], and the compliance of ≥70 years old group was the lowest [9.0% (29/324)]. Colonoscopy examination revealed 606 cases with lesions, the detection rate of lesions was 17.6%, and the male detection rate was significantly higher than that of females [26.9% (313/1162) vs. 12.8% (293/2287), χ(2)=106.140, P<0.001]. The detection rate of lesions increased with age [40-49, 50-59, 60-69, ≥70: 10.9% (119/1091), 17.5% (252/1438), 25.0% (223/891) and 41.4% (12/29), respectively, χ(2)=79.010, P<0.001]. A total of 584 cases underwent endoscopic excision and pathological diagnosis, and 465 cases (13.5%) of precancerous lesions were detected. The prevalence of precancerous lesions in men was higher than that in women [21.3% (247/1162) vs. 9.5% (218/2287), χ(2)=90.801, P<0.001], the precancerous lesion detection rate increased with age [40-49, 50-59, 60-69, ≥70: 8.0% (87/1091), 14.3% (206/1438), 18.1% (161/891) and 37.9% (11/29); χ(2)=58.109, P<0.001]. A total of 4 patients with colorectal cancer were detected, including 3 males and 1 female. The detection rate of male colorectal cancer was 258.2/100 000, and the female was 43.7/100 000, whose difference was not statistically significant (χ(2)=1.488, P=0.223). There was no significant difference in the detection rate of colorectal cancer among 4 age groups [40-49, 50-59, 60-69, ≥70: 91.7/100 000 (1/1091), 69.5/100 000 (1/1438), 224.5/100 000 (2/891) and 0, respectively, P=0.696]. Conclusions: Screening for colorectal cancer is an important measure to control the onset and death of colorectal cancer. Through the questionnaire risk assessment plus colonoscopy, two-step screening method can improve the screening efficiency and greatly reduce the screening cost.

Abstract
PURPOSE The role of Helicobacter pylori as key factor in gastric inflammation and the development of (pre-)cancerous lesions is undisputable. As an open system, the human upper gastrointestinal tract harbors a complex bacterial community which is highly impacted by the absence or presence of H. pylori. The interaction between other bacteria and H. pylori might impact on gastric carcinogenesis. RECENT FINDINGS Several studies demonstrated differences in the composition of the gastric bacterial community in different stages of gastritis and between samples from tumor and adjacent tissue. In addition, animal studies demonstrated an increased and accelerated development of precancerous lesions in mice colonized with intestinal flora and H. pylori compared with mice mono-infected with H. pylori. CONCLUSION Other bacteria beyond H. pylori enter the focus in research on gastric carcinogenesis. However, we are still far from a thorough understanding of the pathophysiology of host-microbiota interaction and its impact on the development of malignant and precancerous changes.

Abstract
Liver cirrhosis is a common kind of chronic liver diseases, with the development of diseases; some patients may gradually develop precancerous lesions, or even progress to hepatocellular carcinoma (HCC). Precancerous lesions of the liver mainly include dysplastic foci (DF) and dysplastic nodules (DN), and most of it occurs on the basis of liver cirrhosis. Thus, recognition of precancerous lesions and liver cirrhosis through screening, combined with imaging and pathological features will identity the nature of nodules in early stage cirrhosis and HCC, and thereby will help to improve the diagnosis rate and clinical prognosis.

Abstract
Hepatocellular carcinoma (HCC) is a major disease with a high degree of malignancy, and poor prognosis, which seriously endangers human health. Chronic viral hepatitis (HBV, HCV)-cirrhosis-liver cancer patterns of pathogenesis has been widely accepted. However, the relationship between non-infectious liver disease and HCC is not completely clear; thereby how various non-infectious liver diseases develop through precancerous lesions has attracted widespread attention to HCC. A full understanding of these precancerous lesions is likely to provide new ideas and strategies for the prevention and treatment of non-infectious liver disease-related HCC.

Abstract
The occurrence of hepatocellular carcinoma (HCC) is a multistep development process through precancerous lesions. A precancerous lesion of HCC is classified into hepatocyte dysplasia at the cytological level and dysplastic nodules at the histological level, and the corresponding lesion subtypes have different risks of canceration. Pathology is the "gold standard" for the diagnosis of early stage HCC and its precancerous lesions. However, it also faces many difficulties and challenges, such as the accumulation of experience in the pathological diagnosis, the understanding and grasp of key points of histopathological diagnosis and differential diagnosis, the combination application of immune and molecular diagnostic markers, and many others. This article briefly discusses the key points of pathological features and differential diagnosis of precancerous lesions of HCC.

Abstract
Objective MicroRNA (miR)-421 plays a key role in cancer progression. It has been reported that circulating miR-421may be a potential tumor marker for the diagnosis of several cancers. However, the role of miR-421 in plasma as a potential biomarker in the diagnosis of precancerous gastric lesions (Pre) and early-stage gastric cancer (GC) remains poorly understood. In this study, we investigated miR-421 in plasma as a novel potential biomarker for the detection of precancerous gastric lesions and early-stage (GC). Materials & Methods The miRNA content was determined by quantitative real-time polymerase chain reaction (qRT-PCR). MiR-421 content in all subjects was normalized by endogenous miRNA (miR-16). The diagnostic value of miR-421 for Pre and GC was assessed by comparing receiver operating characteristic (ROC) analysis with traditional tumor markers, including CEA, CA125, CA153, CA211 and CA50. The correlation between the expression of miR-421 and the pathological characteristics of Pre and GC was analyzed. Results Elevated expression of miR-421 in plasma can robustly distinguish the normal population from Pre and GC cases, especially in the early stages of gastric cancer cases (all p < 0.05). The ROC analyses showed that the area under the ROC curve (AUC), sensitivity, accuracy and Youden index of miR-421 were superior to traditional tumor markers (CEA, CA125, CA153, CA211, and CA50) in GC diagnosis, while its specificity was higher than CEA, CA153 and CA50 (all p < 0.05). MiR-421 in plasma had higher AUC value than AFP, CA153, CA211 and CA50 in the diagnosis of Pre (all p < 0.05), while specificity, accuracy and Youden index of miR-421 was only lower than CA211. The efficiency of miR-421 in the diagnosis of GC was significantly higher than that of CA211 and CA50, and it was significantly higher than CA153, CA211 and CA50 in the diagnosis of Pre (all p < 0.05). In addition, up-regulation of miR-421 occurred initially in precancerous gastric lesions as well as in the early stage of GC. Conclusions Overexpression of plasma miR-421 is a novel biomarker for the detection of precancerous lesions and early gastric cancer.
