AIM:To investigate the impact of es-ketamine-mediated opioid-free anesthesia(OFA)on postoperative gastrointestinal function in patients undergoing laparoscopic distal gastrectomy for gas-tric cancer.METHODS:A total of 150 pa-tients,scheduled for elective laparoscopic distal gas-trectomy for gastric cancer and meeting the inclu-sion and exclusion criteria,were randomly assigned to either the OFA group or the opioid-based anes-thesia(OBA)group using a random number ta-ble,with 75 patients in each group.The OFA group was administered an anesthesia regimen pri-marily consisting of esketamine,while the OBA group received conventional opioid anesthesia,pri-marily consisting of sufentanil and remifentanil.The primary outcome measure was postoperative flatus time,defined as the interval from the end of sur-gery to the first passage of gas.RESULTS:The OFA group exhibited a shorter postoperative flatus time compared to the OBA group(P＜0.01).Intraopera-tive blood loss and norepinephrine consumption were significantly less in the OFA group compared to the OBA group(P＜0.05);the postoperative HADS-D score was better in the OFA group than in the OBA group,and both the OFA and OBA groups showed significantly lower postoperative HADS-A and HADS-D scores compared to their preoperative levels(P＜0.05);the incidence rate of abdominal distension was significantly lower in the OFA group compared to the OBA group(P＜0.05).CONCLUSION:The use of esketamine-mediated opioid-free anesthesia can expedite gastrointestinal function recovery,reduce hospital stay duration,and decrease postoperative adverse reactions in patients undergoing laparo-scopic distal gastrectomy for gastric cancer.

Extramedullary plasmacytoma(EMP)is a malignant neoplasm characterized by monoclonal plasma cell proliferation originating outside the bone marrow and hematopoietic tissues.The co-occurrence of multiple myeloma(MM)with mammary EMP is clinically rare.This case report describes the diagnostic and therapeutic management of a middle-aged female patient with MM and mammary EMP,accompanied by a litera-ture review.The patient presented with persistent fever and was found to have a right breast mass via PET/CT during routine follow-up for MM.The lesion was biopsy-confirmed as mammary EMP,and the patient subse-quently underwent chemotherapy.This case highlights the critical importance of differential diagnosis between breast cancer and rare hematologic metastatic tumors in early prevention of disease progression.

The armadillo repeat containing 5 (ARMC5) gene is part of a family of protein-coding genes that are rich in armadillo repeat sequences, are ubiquitously present in eukaryotes, and mediate interactions between proteins, playing roles in various cellular processes. Current research has demonstrated that reduced expression or absence of the ARMC5 gene in various tumor tissues can lead to uncontrolled cell proliferation, thereby inducing a range of diseases. The ARMC5 gene was initially extensively studied in the context of bilateral macronodular adrenocortical disease (BMAD), with harmful pathogenic variants in ARMC5 identified in approximately 50% of BMAD patients. With advancing research, scientists have discovered that ARMC5 pathogenic variants may also have potential effects on other diseases and could be associated with increased susceptibility to certain cancers. This review aims to present the latest research progress on how the ARMC5 gene plays its role in tumors. It outlines the basic structure of ARMC5 and the regions where it functions, as well as the diseases currently proven to be associated with ARMC5. Moreover, some evidence suggests its relation to embryonic development and the regulation of immune system activity. In conclusion, the ARMC5 gene is a crucial focal point in genetic and medical research. Understanding its function and regulation is of great importance for the development of new therapeutic strategies related to diseases associated with its pathogenic variants.

Objective:To explore the association of 21-gene recurrence score (RS) and clinicopathologic characteristics of hormone receptor (HR) positive T1-3N1M0 breast cancer and its value in prognosis evaluation.Methods:The clinicopathological data of 287 patients with T1-3N1M0 breast cancer were collected, the 21-gene assay was completed, and follow-up was conducted. According to the 21-gene RS, the patients were divided into the RS<26 and RS≥26 groups. The relationship between the 21-gene RS and clinicopathological characteristics, treatment, recurrence, and metastasis was analyzed. Univariate and multivariate statistical analyses were used to analyze the risk factors for disease free survival (DFS).Results:The median RS of the 287 patients was 16. There were 240 cases with RS <26 and 47 cases with RS≥26. Tumor size, grade, estrogen receptor (ER), progesterone receptor (PR), and Ki-67 index were significantly different between the two cohorts ( P<0.05 for all). After a median follow-up of 74 months, the recurrence rate in the RS<26 group (8.3%) was significantly lower than that in the RS≥26 group (23.4%), the locoregional recurrence (LRR) rates in the RS<26 and RS≥26 groups were 2.1% and 0%,and the distant metastasis (DM) rates were 6.3% and 23.4%, respectively. The 5-year relapse free survival (RFS) rates of patients with RS<26 and RS≥26 were 93.8% (95% CI: 90.7%-96.9%) and 87.2% (95% CI: 78.2%-97.3%), and the 5-year DFS rates were 92.1% (95% CI: 88.7%-95.6%) and 85.1% (95% CI: 75.5%-95.9%), respectively, with significant differences between the two cohorts ( P=0.007 and P=0.006, respectively). Univariate analysis showed age, tumor size, grade, PR status, Ki-67 index and RS were prognostic factors for DFS ( P<0.05 for all). Multivariate analysis showed that age and tumor size were independent significant predictors for DFS ( P<0.05). Conclusions:The 21-gene RS of T1-3N1M0 breast cancer is related to tumor size, grade, ER, PR, and Ki-67 index. RS is an important factor affecting DM and DFS.

Objective: The phase 2, open-label, randomized, 3-arm study (NCT03776812) found that intermittently dosed relacorilant + nab-paclitaxel improved progression-free survival, duration of response, and overall survival compared with nab-paclitaxel monotherapy with minimal additional toxicity. This study analyzed the cost-effectiveness of intermittent relacorilant + nab-paclitaxel (IN), continuous relacorilant + nab-paclitaxel (CN) and nabpaclitaxel monotherapy (N) from the payer’s perspective over a 5-year time horizon. Methods: The health outcome is expressed in quality-adjusted life years (QALYs). IN, CN and N were evaluated using QALYs and incremental cost-effectiveness ratio (ICER). The data for this model come from the NCT03776812 trial and other published literature. The impact of the variables is studied using a one-way deterministic sensitivity analysis and a probabilistic sensitivity analysis based on a second-order Monte Carlo simulation. Results: N was the least costly strategy, at $ 4606.05, followed by IN ($22,597.75) and CN ($44,276.86). Based on a willingness-to-pay threshold of $100,000/QALY, IN was costeffective compared with N, with an ICER of $21,418.69 per QALY gained for N, whereas CN was ruled out by extended dominance (less effective, more costly), compared with N. The incremental benefits of IN compared to CN and N were 0.72 QALYs and 0.84 QALYs. Conclusion From a US health care system perspective, IN may be cost-effective compared to CN for patients with recurrent platinum-resistant ovarian cancer, and IN is also better than CN and N in terms of efficacy. Therefore, IN is a high-quality regimen for clinicians to treat patients with recurrent platinum-resistant ovarian cancer.
