Meta-analysis was performed using Stata 16.0 software. And we applied the random-effects models to estimate the combined effect values due to the high heterogeneity. <b>Results:</b> Twenty-three studies were eligible. The relative prevalence of CADC was 9.0% (95% <i>CI</i>, 7.7%－10.3%). According to the diagnosis time of ICC, the patients were divided into three time periods, which is 1979-2005, 2006-2011, 2012-2022 respectively. The prevalence of CADC by time was: 6.0% in 1979-2005, 8.1% in 2006-2011, and 9.5% in 2012-2022, respectively, with no statistically significant trend in proportions over time (χ²=5.03, <i>P</i>=0.081). Meanwhile, the percentage of CADC also varies by regions, and the highest percentage of CADC was found in the eastern region (11.2%), followed by the western region (7.3%) and the central region (5.9%). The total prevalence of HPV infection in CADC was 72.3%, which was lower than 92.0% in SCC, and the difference was statistically significant (χ²=300.89, <i>P</i>＜0.01). To be specific, the top three HPV types prevalent in CADC were HPV18 (45.0%), HPV16 (22.0%), and HPV52 (7.3%), and those prevalent in the SCC were HPV16 (64.2%), HPV52 (5.6%), HPV18 (5.4%). The results of the Egger's test, and Begg's test showed that there was no publication bias in this study and sensitivity analysis showed that the results of this study were fairly stable. <b>Conclusions:</b> The proportion of CADC in China has increased in a limited way in the past decades, and there are regional differences in the proportion of CADC. The predominant type is HPV18 in CADC and HPV16 in SCC. To eliminate the limitations of the secondary literature, a multicenter study with consistent diagnostic levels and identical HPV genotyping tests is still needed in the future to better characterize the relative proportion of cervical adenocarcinoma and the trend of HPV changes, which will provide a basis for the improvement of HPV vaccine and screening policies.</p>","PeriodicalId":39868,"journal":{"name":"中华肿瘤杂志","volume":"46 12","pages":"1209-1217"},"PeriodicalIF":0.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142847663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Small cell lung cancer (SCLC) is a highly aggressive neuroendocrine tumor that is closely associated with tobacco exposure, accounting for 13% to 15% of all lung cancer cases. It is characterized by a high proliferation rate and exceptional metastatic capacity. At the time of diagnosis, approximately 70% of the patients have metastasized and are classified as extensive-stage small cell lung cancer (ES-SCLC). From 1980 to 2018, chemotherapy and radiotherapy were the main treatment strategies for SCLC. Etoposide combined with platinum has remained the standard first-line treatment for ES-SCLC. Although SCLC is very sensitive to initial treatment, the majority of patients have disease progression within 6 months, and treatment options after recurrence are very limited, and the median survival time is only about 8-10 months. The advent of immune checkpoint inhibitors (ICIs), particularly programmed death-ligand 1 (PD-L1) and programmed death -1 (PD-1) inhibitors, has brought new hope to patients with SCLC. PD-1/PD-L1 plus chemotherapy have significantly prolonged overall survival of patients with ES-SCLC, which has become the new standard of first-line treatment for ES-SCLC. Currently, a raised number of immune checkpoint inhibitors (ICIs) have been approved in China for the treatment of SCLC, providing more treatment options for SCLC patients.

With the deepening of clinical research on presacral cysts, some new problems have been found to be overcome. On the basis of the Chinese Expert Consensus on Standardized Treatment of Presacral Cysts (2021 edition), the Pelvic Tumor Integration Professional Committee of the Chinese Anti-Cancer Association organized authoritative experts in relevant professional fields including general surgery, gastrointestinal surgery, colorectal and anal surgery, gynecological oncology, bone and soft tissue surgery, neurosurgery, pathology, imaging and other departments, to formulate the Chinese Expert Consensus on the Standardized Diagnosis and Treatment of Presacral Cysts (2024 edition) after a consensus meeting. The 2024 consensus provides a comprehensive introduction to the following seven aspects, including the origin and pathology of presacral cysts, related anatomy and classification of surgery, diagnosis and differential diagnosis, surgical philosophy, surgical methods for excision, perioperative complications and management, follow-up, and subsequent treatment, and has reached a consensus after repeated discussions and revisions. Compared with the 2021 consensus, the main updates in the 2024 consensus include the following aspects: in the anatomy and classification section, the anatomical classification of high and low, single and multiple cysts of the presacral space has been added; in the surgical concept section, it is emphasized to protect the sacral nerves for presacral cysts with sacral variations; in the surgical approach section for excision, the surgical approach for different anatomical types of presacral cysts has been further clarified. For patients with preoperative enterocutaneous fistula, the use of gluteus maximus muscle flap to repair the fistula reduces the probability of preventive stoma.

The clinical data and surgical resection tissue specimens of 196 patients with esophageal squamous cell carcinoma who received surgery combined with radiotherapy at Henan Provincial Chest Hospital from January 2013 to May 2022 were collected. Immunohistochemistry was used to detect the expression of Oct4 protein in the tumor and adjacent tissues. The lentiviral packaging system was used to construct esophageal squamous cell carcinoma cell lines that up-regulated or down-regulated Oct4. The cell counting kit 8 (CCK-8) was used to detect the cell proliferation ability, the scratch test was used to detect the cell migration ability, and the clone formation test was used to detect the cell radiosensitivity. Immunofluorescence experiment was used to detect DNA damage level, and Western blot was used to detect the expressions of Oct4, human phosphorylated histone (γ-H2AX), E-cadherin, N-cadherin, vimentin, and zinc finger E box binding homology box 1 (ZEB1). &lt;b&gt;Results:&lt;/b&gt; The analysis of GEPIA database showed that the expression level of Oct4 mRNA in esophageal carcinoma was higher than that in paracancerous tissues.

Propensity score matching (PSM) was performed in the two groups. After PSM, 120 patients were allocated to the nCRT group and 192 patients to the nCIT group. The pathological response and disease recurrence were compared between the two groups after PSM. Log rank test were used to compare the survival outcomes before and after PSM. Univariate and multivariate Cox regression analyses were performed to identify the prognostic factors for locally advanced ESCC. <b>Results:</b> After PSM, the R0 resection rate in the nCRT group and the nCIT group was 93.3% (112/120) and 93.8% (180/192), respectively, with no statistical significance (<i>P</i>=0.884). However, the pathological complete response rate in the nCRT group [36.7% (44/120)] was higher than that in the nCIT group [21.4% (41/192), <i>P</i>=0.003]. For patients with R0 resection, the major recurrence pattern was distant metastasis [18.8% (21/112)] in the nCRT group, while the pattern was locoregional recurrence [12.2% (22/180)] in the nCIT group. The 3-year disease-free survival rates were 52.7% and 66.1% (<i>P</i>=0.022) and the 3-year overall survival rates were 59.2% and 75.5% (<i>P</i>=0.002) in the nCRT and nCIT groups, respectively. Multivariate Cox regression analysis also revealed that the neoadjuvant therapy mode was an independent prognostic factor for patients with locally advanced ESCC. Compared with nCRT, nCIT could significantly prolong disease-free survival (<i>HR</i>=0.58, 95% <i>CI</i>: 0.40-0.86) and overall survival (<i>HR</i>=0.53, 95% <i>CI</i>: 0.35-0.79). <b>Conclusion:</b> These results suggest that nCIT could significantly improve disease-free survival rate and overall survival rate over nCRT in locally advanced ESCC, even with lower pathological complete response rate.</p>","PeriodicalId":39868,"journal":{"name":"中华肿瘤杂志","volume":"46 11","pages":"1058-1066"},"PeriodicalIF":0.0,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142773350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
