Magnetic resonance imaging (MRI)-guided wire localization can be applied to assist to remove suspected breast lesions accurately. This study aimed to evaluate the clinical application value of this technique in Chinese women.A total of 126 patients (131 lesions) who had underwent such technique in our hospital from April 2017 to June 2023 were enrolled. 1.5T MRI system and a wire localization device were used. Image characteristics, clinical features and postoperative pathology were collected and analyzed.All of 126 patients (131 lesions) were successfully localized by MRI and excised for biopsy. There were 39 malignant lesions (29.77%) and 92 benign lesions (70.23%). There was no significant correlation between the morphology of DCE-MRI and the ratio of malignant lesions (P=0.763), while there was a statistical correlation between the BPE, TIC curve and the malignancy rate (P<0.05). All the lesions were assessed according to BI-RADS category of MRI (C4A=77, C4B=40, C4C=12, C5=2). The malignancy rates were as follows: 16.88% for 4A lesions (13/77), 37.50% for 4B lesions (15/40), 75.00% for 4C lesions (9/12) and 100% for 5 lesions (2/2). There was a significant correlation between the BI-RADS category and the incidence of benign-to-malignant lesions (P<0.001).MRI-guided wire localization can assist to remove suspected breast lesions early, safely and accurately. This technique makes up for the deficiency of X-ray and ultrasound, improves the accuracy of diagnosis and resection therapy in intraductal carcinoma and early invasive carcinoma, and helps to improve the the prognosis of breast cancer.
磁共振成像(MRI)引导下的线定位技术可用于辅助准确切除可疑乳腺病灶。本研究旨在评估该技术在中国女性中的临床应用价值。研究对象为2017年4月至2023年6月在我院接受该技术的126例患者(131个病灶)。采用1.5T磁共振成像系统和线定位装置。所有 126 例患者(131 个病灶)均通过 MRI 成功定位并切除活检。其中恶性病变 39 例(29.77%),良性病变 92 例(70.23%)。DCE-MRI的形态与恶性病变的比例无明显相关性(P=0.763),而BPE、TIC曲线与恶性率有统计学相关性(P<0.05)。所有病变均根据磁共振成像的 BI-RADS 分类(C4A=77、C4B=40、C4C=12、C5=2)进行评估。恶性率如下4A病变为16.88%(13/77),4B病变为37.50%(15/40),4C病变为75.00%(9/12),5病变为100%(2/2)。BI-RADS类别与良性病变转化为恶性病变的发生率之间存在明显的相关性(P<0.001)。该技术弥补了X光和超声检查的不足,提高了导管内癌和早期浸润癌诊断和切除治疗的准确性,有助于改善乳腺癌的预后。

Laparoscopic total gastrectomy plus lymph node dissection is an effective treatment method for patients with gastric cancer. With the development and popularization of laparoscopic techniques in recent years, surgeons have become more skilled in laparoscopic techniques. Totally laparoscopic total gastrectomy (TLTG) has been developed; however, digestive tract reconstruction remains difficult, especially with anastomosis of the esophagus and jejunum. Using the self-pulling and latter transection (SPLT) method combined with a linear stapler has effectively solved the problem of narrow space in esophagojejunostomy. Here, we examined the safety and effectiveness of the SPLT technique in TLTG compared with SPLT with traditional esophagojejunostomy overlap anastomosis.We retrospectively analyzed all patients with gastric cancer admitted to the Department of Gastrointestinal Surgery of the Second Affiliated Hospital of Fujian Medical University from September 2020 to September 2023. In total, 158 patients met the inclusion criteria and were included. Patients were grouped according to whether the lower esophagus was transected after self-pulling. Patient demographics, tumor characteristics, surgical conditions, and postoperative results between the two groups were statistically analyzed.A total of 158 patients were included in the study. All patients underwent TLTG and completed intracavitary anastomosis. There were 70 cases (44%) in the SPLT-Overlap group and 88 cases (56%) in the traditional overlap group. There was no significant difference in demographic and oncological characteristics between the two groups. The operation time (P = 0.002) and esophageal jejunum anastomosis time (P<0.001) were significantly shorter in the SPLT-Overlap group compared with the traditional overlap group. The intraoperative blood loss of the SPLT-Overlap group was 80.29 ± 36.36 ml, and the intraoperative blood loss of the traditional overlap group was 101.40 ± 46.68 ml. The difference was statistically significant (P=0.003). The SPLT-Overlap group also achieved a higher upper cutting edge (P =0.03). There was no significant difference between the two groups in terms of the incision size, postoperative hospital stay, time to first flatus, time to first liquid intake, drainage tube removal time, and esophagojejunal anastomotic diameter. There were 15 and 19 cases of short-term postoperative complications in the SPLT-Overlap and traditional Overlap groups, respectively. All patients received R0 resection, and no secondary surgery or death occurred.We applied SPLT to overlap anastomosis. Short-term, SPLT has good safety and feasibility in TLTG. It can effectively shorten the time of digestive tract reconstruction, simplify the reconstruction procedure, and make the digestive tract reconstruction simple and fast; at the same time, a safe cutting edge can be obtained.
腹腔镜全胃切除术加淋巴结清扫术是治疗胃癌患者的有效方法。近年来,随着腹腔镜技术的发展和普及,外科医生对腹腔镜技术的掌握也越来越娴熟。全腹腔镜全胃切除术(TLTG)已经发展起来,但消化道重建仍然困难重重,尤其是食管和空肠的吻合。使用自拉后横切(SPLT)方法结合线性订书机有效地解决了食管空肠吻合术空间狭窄的问题。我们回顾性分析了福建医科大学附属第二医院胃肠外科自2020年9月至2023年9月收治的所有胃癌患者。共有 158 名患者符合纳入标准并被纳入。根据患者是否在自拉后横断食管下段进行分组。研究对两组患者的人口统计学特征、肿瘤特征、手术条件和术后结果进行了统计分析。所有患者均接受了TLTG手术,并完成了腔内吻合术。SPLT-重叠组有70例(44%),传统重叠组有88例(56%)。两组患者的人口统计学和肿瘤学特征无明显差异。与传统重叠组相比,SPLT-重叠组的手术时间(P = 0.002)和食管空肠吻合时间(P<0.001)明显缩短。SPLT-Overlap 组的术中失血量为 80.29 ± 36.36 毫升,而传统重叠组的术中失血量为 101.40 ± 46.68 毫升。差异有统计学意义(P=0.003)。SPLT-Overlap 组也获得了更高的上切缘(P=0.03)。两组在切口大小、术后住院时间、首次排气时间、首次进食液体时间、拔除引流管时间和食管空肠吻合口直径方面没有明显差异。SPLT-Overlap组和传统Overlap组分别有15例和19例术后短期并发症。我们将SPLT应用于重叠吻合术。短期来看,SPLT在TLTG中具有良好的安全性和可行性。短期来看,SPLT在TLTG中具有良好的安全性和可行性,它能有效缩短消化道重建的时间,简化重建程序,使消化道重建简单快捷,同时还能获得安全的切缘。

Ovarian carcinosarcoma (OCS) is an unusual ovarian cancer type characterized by distinct carcinomatous and sarcomatous components. OCS has been excluded from many of the pan-histotype studies of ovarian carcinoma, limiting our understanding of its behavior.We performed a multi-cohort cross-sectional study of characteristics and outcomes in ovarian cancer patients from Scotland (n=2082) and the Surveillance, Epidemiology and End Results Program (SEER, n=44946) diagnosed with OCS or one of the other major histotypes: high grade serous (HGSOC), endometrioid (EnOC), clear cell (CCOC), mucinous (MOC) or low grade serous ovarian carcinoma (LGSOC). Differences in overall survival were quantified using Cox regression models to calculate hazard ratios (HR).Across both cohorts, OCS patients were significantly older at diagnosis compared to all other histotypes (median age at diagnosis 69 and 67 in Scottish and SEER cohorts) and demonstrated the shortest survival time upon univariable analysis. Within the Scottish cohort, 59.3% and 16.9% of OCS patients presented with FIGO stage III and IV disease, respectively; this was significantly higher than in EnOC, CCOC or MOC (P<0.0001 for all), but lower than in HGSOC (P=0.004). Multivariable analysis accounting for other prognostic factors identified OCS as independently associated with significantly shorter survival time compared to HGSOC, EnOC, LGSOC and MOC in both the Scottish (multivariable HR vs OCS: HGSOC 0.45, EnOC 0.39, LGSOC 0.26, MOC 0.43) and SEER cohorts (multivariable HR vs OCS: HGSOC 0.59, EnOC 0.34, LGSOC 0.30, MOC 0.81). Within the SEER cohort, OCS also demonstrated shorter survival compared to CCOC (multivariable HR 0.63, 95% CI 0.58-0.68), but this was not replicated within the Scottish cohort (multivariable HR for CCOC: 1.05, 95% CI 0.74-1.51). Within early-stage disease specifically (FIGO I-II or SEER localized stage), OCS was associated with the poorest survival of all histotypes across both cohorts. In the context of late-stage disease (FIGO III-IV or SEER distant stage), OCS, MOC and CCOC represented the histotypes with poorest survival.OCS is a unique ovarian cancer type that affects older women and is associated with exceptionally poor outcome, even when diagnosed at earlier stage. New therapeutic options are urgently required to improve outcomes.
卵巢癌肉瘤(OCS)是一种不常见的卵巢癌类型,其特点是具有不同的癌变和肉瘤成分。在许多卵巢癌的泛组型研究中,卵巢癌都被排除在外,这限制了我们对其行为的了解。我们对来自苏格兰(n=2082)和监测、流行病学和最终结果计划(SEER,n=44946)的卵巢癌患者的特征和结局进行了多队列横断面研究,这些患者被诊断为 OCS 或其他主要组织类型之一:高级别浆液性卵巢癌(HGSOC)、子宫内膜样卵巢癌(EnOC)、透明细胞卵巢癌(CCOC)、粘液性卵巢癌(MOC)或低级别浆液性卵巢癌(LGSOC)。在这两个队列中,OCS 患者的诊断年龄明显大于所有其他组织类型(苏格兰队列和 SEER 队列的诊断年龄中位数分别为 69 岁和 67 岁),并且在单变量分析中显示出最短的生存时间。在苏格兰队列中,分别有59.3%和16.9%的OCS患者出现FIGO III期和IV期疾病;这一比例明显高于EnOC、CCOC或MOC(P<0.0001),但低于HGSOC(P=0.004)。在苏格兰队列(多变量 HR vs OCS:HGSOC 0.45、EnOC 0.39、LGSOC 0.26、MOC 0.43)和 SEER 队列(多变量 HR vs OCS:HGSOC 0.59、EnOC 0.34、LGSOC 0.30、MOC 0.81)中,考虑到其他预后因素的多变量分析发现,与 HGSOC、EnOC、LGSOC 和 MOC 相比,OCS 与生存时间明显较短独立相关。在 SEER 队列中,OCS 的生存期也比 CCOC 短(多变量 HR 为 0.63,95% CI 为 0.58-0.68),但这一情况在苏格兰队列中没有得到验证(CCOC 的多变量 HR 为 1.05,95% CI 为 0.74-1.51)。具体到早期疾病(FIGO I-II 期或 SEER 局限期),在两个队列的所有组织类型中,OCS 与最差的生存率相关。在晚期疾病(FIGO III-IV 或 SEER 远处分期)中,OCS、MOC 和 CCOC 代表了生存率最差的组织类型。卵巢癌是一种独特的卵巢癌类型,主要影响老年妇女,即使在早期诊断时,预后也非常差。

Distinguishing between prostatic cancer (PCa) and chronic prostatitis (CP) is sometimes challenging, and Gleason grading is strongly associated with prognosis in PCa. The continuous-time random-walk diffusion (CTRW) model has shown potential in distinguishing between PCa and CP as well as predicting Gleason grading.This study aimed to quantify the CTRW parameters (α, β & Dm) and apparent diffusion coefficient (ADC) of PCa and CP tissues; and then assess the diagnostic value of CTRW and ADC parameters in differentiating CP from PCa and low-grade PCa from high-grade PCa lesions.Retrospective (retrospective analysis using prospective designed data).Thirty-one PCa patients undergoing prostatectomy (mean age 74 years, range 64–91 years), and thirty CP patients undergoing prostate needle biopsies (mean age 68 years, range 46–79 years).MRI scans on a 3.0T scanner (uMR790, United Imaging Healthcare, Shanghai, China). DWI were acquired with 12 b-values (0, 50, 100, 150, 200, 500, 800, 1200, 1500, 2000, 2500, 3000 s/mm2).CTRW parameters and ADC were quantified in PCa and CP lesions.The Mann-Whitney U test was used to evaluate the differences in CTRW parameters and ADC between PCa and CP, high-grade PCa, and low-grade PCa. Spearman’s correlation of the pathologic grading group (GG) with CTRW parameters and ADC was evaluated. The usefulness of CTRW parameters, ADC, and their combinations (Dm, α and β; Dm, α, β, and ADC) to differentiate PCa from CP and high-grade PCa from low-grade PCa was determined by logistic regression and receiver operating characteristic curve (ROC) analysis. Delong test was used to compare the differences among AUCs.Significant differences were found for the CTRW parameters (α, Dm) between CP and PCa (all P<0.001), high-grade PCa, and low-grade PCa (α:P=0.024, Dm:P=0.021). GG is correlated with certain CTRW parameters and ADC(α:P<0.001,r=-0.795; Dm:P<0.001,r=-0.762;ADC:P<0.001,r=-0.790). Moreover, CTRW parameters (α, β, Dm) combined with ADC showed the best diagnostic efficacy for distinguishing between PCa and CP as well as predicting Gleason grading. The differences among AUCs of ADC, CTRW parameters and their combinations were not statistically significant (P=0.051–0.526).CTRW parameters α and Dm, as well as their combination were beneficial to distinguish between CA and PCa, low-grade PCa and high-grade PCa lesions, and CTRW parameters and ADC had comparable diagnostic performance.
区分前列腺癌(PCa)和慢性前列腺炎(CP)有时具有挑战性,而格里森分级与PCa的预后密切相关。本研究旨在量化 PCa 和 CP 组织的 CTRW 参数(α、β 和 Dm)和表观扩散系数(ADC),然后评估 CTRW 和 ADC 参数在区分 CP 和 PCa 以及低级别 PCa 和高级别 PCa 病变方面的诊断价值。31名接受前列腺切除术的PCa患者(平均年龄74岁,范围64-91岁)和30名接受前列腺穿刺活检的CP患者(平均年龄68岁,范围46-79岁)在3.0T扫描仪(uMR790,中国上海联合成像医疗有限公司)上进行核磁共振成像扫描。采用 Mann-Whitney U 检验评估 PCa 和 CP、高级别 PCa 和低级别 PCa 之间 CTRW 参数和 ADC 的差异。评估了病理分级组(GG)与 CTRW 参数和 ADC 的斯皮尔曼相关性。通过逻辑回归和接收器操作特征曲线(ROC)分析确定了 CTRW 参数、ADC 及其组合(Dm、α 和 β;Dm、α、β 和 ADC)在区分 PCa 和 CP 以及高级别 PCa 和低级别 PCa 方面的作用。结果发现,CP 和 PCa 之间的 CTRW 参数(α、Dm)、高级别 PCa 和低级别 PCa 之间的 CTRW 参数(α:P=0.024,Dm:P=0.021)存在显著差异(均 P<0.001)。GG 与某些 CTRW 参数和 ADC 相关(α:P<0.001,r=-0.795;Dm:P<0.001,r=-0.762;ADC:P<0.001,r=-0.790)。此外,CTRW参数(α、β、Dm)与ADC相结合,在区分PCa和CP以及预测Gleason分级方面显示出最佳诊断效果。ADC、CTRW参数及其组合的AUC差异无统计学意义(P=0.051-0.526)。CTRW参数α和Dm及其组合有利于区分CA和PCa、低级别PCa和高级别PCa病变,CTRW参数和ADC的诊断效果相当。

Laparoscopic left hemihepatectomy (LLH) is commonly used for benign and malignant left liver lesions. We compared the benefits and drawbacks of LLH from the head side approach (LLHH) with those of conventional laparoscopic left hemihepatectomy (CLLH). This study was conducted to investigate the safety and feasibility of LLHH by comparing it with CLLH.In this study, 94 patients with tumor or hepatolithiasis who underwent LLHH (n = 39) and CLLH (n = 55) between January 2016 and January 2023 were included. The preoperative features, intraoperative details, and postoperative outcomes were compared between the two groups.For hepatolithiasis, patients who underwent LLHH exhibited shorter operative time (p = 0.035) and less blood loss (p = 0.023) than those who underwent CLLH. However, for tumors, patients undergoing LLHH only showed shorter operative time (p = 0.046) than those undergoing CLLH. Moreover, no statistically significant differences in hospital stay, transfusion, hospital expenses, postoperative white blood cell (WBC) count, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were observed between the two groups (p > 0.05) for tumor or hepatolithiasis. For hepatocellular carcinoma (HCC), no differences in both overall survival (p = 0.532) and disease-free survival (p = 0.274) were observed between the two groups.LLHH is a safe and feasible surgical procedure for tumors or hepatolithiasis of the left liver.
腹腔镜左半肝切除术(LLH)常用于良性和恶性左肝病变。我们比较了从头侧入路(LLHH)和传统腹腔镜左半肝切除术(CLLH)的优点和缺点。本研究纳入了2016年1月至2023年1月期间接受LLHH(39例)和CLLH(55例)手术的94例肿瘤或肝结石患者。与接受 CLLH 的患者相比,接受 LLHH 的肝结石患者手术时间更短(P = 0.035),失血量更少(P = 0.023)。然而,就肿瘤而言,接受 LLHH 治疗的患者仅比接受 CLLHH 治疗的患者手术时间短(p = 0.046)。此外,对于肿瘤或肝结石,两组患者在住院时间、输血、住院费用、术后白细胞计数、丙氨酸氨基转移酶(ALT)和天冬氨酸氨基转移酶(AST)方面均无统计学差异(P > 0.05)。对于肝细胞癌(HCC),两组患者的总生存期(p = 0.532)和无病生存期(p = 0.274)均无差异。

We report a case of slipped capital femoral epiphysis (SCFE), an on target skeletal toxicity of a pan-FGFR TKI inhibitor, erdafitinib. A 13-year-old boy was diagnosed to have an optic pathway/hypothalamic glioma with signs of increased intracranial pressure and obstructive hydrocephalus requiring placement of ventriculo-peritoneal (VP) shunt. Sequencing of the tumor showed FGFR1-tyrosine kinase domain internal tandem duplication (FGFR1-KD-ITD). He developed hypothalamic obesity with rapid weight gain and BMI >30. At 12 weeks of treatment with erdafitinib, he developed persistent knee pain. X-ray of the right hip showed SCFE. Erdafitinib was discontinued, and he underwent surgical pinning of the right hip. MRI at discontinuation of erdafitinib showed a 30% decrease in the size of the tumor, which has remained stable at 6 months follow-up. Our experience and literature review suggest that pediatric patients who are treated with pan-FGFR TKIs should be regularly monitored for skeletal side effects.
我们报告了一例股骨骨骺滑脱(SCFE)病例,这是一种泛表皮生长因子受体 TKI 抑制剂厄达非替尼的目标骨骼毒性。一名13岁男孩被诊断患有视通路/下丘脑胶质瘤,并伴有颅内压增高和梗阻性脑积水,需要进行脑室-腹膜(VP)分流术。肿瘤测序结果显示为表皮生长因子受体1-酪氨酸激酶结构域内部串联重复(FGFR1-KD-ITD)。他出现了下丘脑肥胖症,体重迅速增加,体重指数(BMI)大于 30。在接受厄达非替尼治疗12周后,他出现了持续性膝关节疼痛。右髋部X光片显示他患有SCFE。他停用了厄达菲尼,并接受了右髋关节置钉手术。停用厄达非尼后的核磁共振成像显示肿瘤缩小了30%,随访6个月后肿瘤仍保持稳定。我们的经验和文献综述表明,接受泛FGFR TKIs治疗的儿童患者应定期监测骨骼副作用。

Nasopharyngeal carcinoma (NPC) is commonly diagnosed at an advanced stage with a high incidence rate in Southeast Asia and Southeast China. However, the limited availability of NPC patient survival data in public databases has resulted in less rigorous studies examining the prediction of NPC survival through construction of Kaplan-Meier curves. These studies have primarily relied on small samples of NPC patients with progression-free survival (PFS) information or data from head and neck squamous cell carcinoma (HNSCC) studies almost without NPC patients. Thus, we coanalyzed RNA expression profiles in eleven datasets (46 normal (control) vs 160 tumor (NPC)) downloaded from the Gene Expression Omnibus (GEO) database and survival data provided by Jun Ma from Sun Yat-sen University. Then, differential analysis, gene ontology (GO) enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and network analysis were performed using STRING database. After that, 2142 upregulated differentially expressed genes (DEGs) and 3857 downregulated DEGs were screened. Twenty-five of them were identified as hub genes, which were enriched in several pathways (cilium movement, extracellular matrix structural constituent, homologous recombination and cell cycle). Utilizing the comprehensive dataset we amassed from GEO database, we conducted a survival analysis of DEGs and subsequently constructed survival models. Seven DEGs (RASGRP2, MOCOS, TTC9, ARHGAP4, DPM3, CD37, and CD72) were identified and closely related to the survival prognosis of NPC. Finally, qRT-PCR, WB and IHC were performed to confirm the elevated expression of RASGRP2 and the decreased expression of TTC9, CD37, DPM3 and ARHGAP4, consistent with the DEG analysis. Conclusively, our findings provide insights into the novel prognostic biomarkers of NPC by mega-data bioinformatics analysis, which suggests that they may serve special targets in the treatment of NPC.
鼻咽癌(NPC)通常在晚期才被确诊,在东南亚和中国东南部发病率较高。然而,由于公共数据库中鼻咽癌患者的生存数据有限,因此通过构建卡普兰-梅耶曲线来预测鼻咽癌生存期的研究不够严谨。这些研究主要依赖于有无病程生存(PFS)信息的鼻咽癌患者小样本,或几乎没有鼻咽癌患者的头颈部鳞状细胞癌(HNSCC)研究数据。因此,我们共同分析了从基因表达总库(GEO)数据库下载的11个数据集(46个正常人(对照组)与160个肿瘤(鼻咽癌))中的RNA表达谱,以及中山大学马骏提供的生存数据。然后,利用 STRING 数据库进行了差异分析、基因本体(GO)富集、京都基因组百科全书(KEGG)通路分析和网络分析。随后,筛选出了2142个上调差异表达基因(DEGs)和3857个下调差异表达基因(DEGs)。其中25个基因被鉴定为中枢基因,它们在多个通路(纤毛运动、细胞外基质结构成分、同源重组和细胞周期)中富集。利用我们从 GEO 数据库中收集的综合数据集,我们对 DEGs 进行了生存分析,并随后构建了生存模型。我们发现了七个 DEGs(RASGRP2、MOCOS、TTC9、ARHGAP4、DPM3、CD37 和 CD72)与鼻咽癌的生存预后密切相关。最后,通过 qRT-PCR、WB 和 IHC 检测证实,RASGRP2 表达升高,TTC9、CD37、DPM3 和 ARHGAP4 表达降低,这与 DEG 分析结果一致。最后,我们的研究结果通过巨型数据生物信息学分析为鼻咽癌的新型预后生物标志物提供了见解,这表明它们可能成为治疗鼻咽癌的特殊靶点。

Case report: Regression after low-dose glucocorticoid therapy in a case of acute immune myocarditis induced by anti-PD-1 therapy for NSCLC 病例报告:一例 NSCLC 抗 PD-1 治疗诱发的急性免疫性心肌炎患者在接受小剂量糖皮质激素治疗后病情缓解

PD-1 inhibitors exhibit efficacy in managing unresectable/metastatic driver gene-negative NSCLC, albeit with potential immune-related adverse events (irAEs). Among these, immune checkpoint inhibitor-associated myocarditis (ICI-M) is rare yet lethal. This study presents the initial successful instance of ICI-M in a lung cancer patient, rescued by low-dose glucocorticoids post-deterioration during treatment.A 78-year-old male with a medical history of stage IV pT3N2M1 NSCLC underwent four cycles of palliative chemotherapy, resulting in stable disease (SD). Subsequent to declining further chemotherapy, the patient was transitioned to a targeted therapy regimen comprising Anlotinib in conjunction with PD-1 inhibitor immunotherapy. On the 26th day post-administration of the PD-1 inhibitor, the patient manifested Grade 2 immune-mediated myocarditis. Treatment encompassing 1mg/kg methylprednisolone combined with immunoglobulin shock therapy was initiated for 3 days, achieving symptomatic control. Nonetheless, upon tapering methylprednisolone dosage to 4–8mg/3–4d, the condition deteriorated, necessitating transfer to the intensive care unit. Methylprednisolone dosage was escalated to 80mg/day for 3 days, followed by gradual reduction by one-third to two-thirds weekly, culminating in the patient’s safe discharge from the hospital.Immune-related myocarditis linked to checkpoint inhibitors is often managed effectively with high-dose glucocorticoid therapy. However, in Asian populations, low-dose glucocorticoids are increasingly utilized for salvage therapy, yielding favorable outcomes and improving prognosis compared to European populations.
PD-1抑制剂在治疗不可切除/转移性驱动基因阴性NSCLC方面表现出疗效,但也存在潜在的免疫相关不良事件(irAEs)。其中,免疫检查点抑制剂相关心肌炎(ICI-M)虽然罕见,但却是致命的。本研究介绍了一名肺癌患者在治疗期间病情恶化后使用小剂量糖皮质激素挽救ICI-M的首次成功病例。一名78岁的男性患者病史为IV期pT3N2M1 NSCLC,接受了四个周期的姑息化疗,结果病情稳定(SD)。在拒绝进一步化疗后,患者接受了由安洛替尼和PD-1抑制剂免疫疗法组成的靶向治疗方案。在使用 PD-1 抑制剂后的第 26 天,患者出现了 2 级免疫介导的心肌炎。患者接受了为期3天的治疗,包括1毫克/千克甲基强的松龙联合免疫球蛋白冲击疗法,症状得到控制。然而,将甲基强的松龙剂量减至 4-8 毫克/3-4 天后,病情恶化,不得不转入重症监护室。甲基强的松龙剂量增至80毫克/天,持续3天,随后每周逐渐减少三分之一至三分之二,最终患者安全出院。然而,在亚洲人群中,低剂量糖皮质激素越来越多地被用于挽救治疗,与欧洲人群相比,它能产生良好的疗效并改善预后。

To develop and validate a nomogram based on extracellular volume (ECV) fraction derived from dual-energy CT (DECT) for preoperatively predicting microsatellite instability (MSI) status in gastric cancer (GC).A total of 123 patients with GCs who underwent contrast-enhanced abdominal DECT scans were retrospectively enrolled. Patients were divided into MSI (n=41) and microsatellite stability (MSS, n=82) groups according to postoperative immunohistochemistry staining, then randomly assigned to the training (n=86) and validation cohorts (n=37). We extracted clinicopathological characteristics, CT imaging features, iodine concentrations (ICs), and normalized IC values against the aorta (nICs) in three enhanced phases. The ECV fraction derived from the iodine density map at the equilibrium phase was calculated. Univariate and multivariable logistic regression analyses were used to identify independent risk predictors for MSI status. Then, a nomogram was established, and its performance was evaluated by ROC analysis and Delong test. Its calibration performance and clinical utility were assessed by calibration curve and decision curve analysis, respectively.The ECV fraction, tumor location, and Borrmann type were independent predictors of MSI status (all P < 0.05) and were used to establish the nomogram. The nomogram yielded higher AUCs of 0.826 (0.729–0.899) and 0.833 (0.675–0.935) in training and validation cohorts than single variables (P<0.05), with good calibration and clinical utility.The nomogram based on DECT-derived ECV fraction has the potential as a noninvasive biomarker to predict MSI status in GC patients.
目的:开发并验证一种基于双能CT(DECT)得出的细胞外体积(ECV)分数的提名图,用于术前预测胃癌(GC)的微卫星不稳定性(MSI)状态。根据术后免疫组化染色将患者分为MSI组(41人)和微卫星稳定性组(82人),然后随机分配到训练组(86人)和验证组(37人)。我们提取了三个增强阶段的临床病理特征、CT成像特征、碘浓度(ICs)和针对主动脉的归一化IC值(nICs)。计算平衡期碘密度图得出的 ECV 分数。采用单变量和多变量逻辑回归分析来确定 MSI 状态的独立风险预测因素。然后,建立了一个提名图,并通过 ROC 分析和 Delong 检验对其性能进行了评估。ECV分数、肿瘤位置和Borrmann类型是MSI状态的独立预测因素(均P<0.05),并被用于建立提名图。在训练组和验证组中,提名图的AUC值分别为0.826(0.729-0.899)和0.833(0.675-0.935),高于单一变量(P<0.05),具有良好的校准性和临床实用性。

The nomogram yielded higher AUCs of 0.826 (0.729–0.899) and 0.833 (0.675–0.935) in training and validation cohorts than single variables (P<0.05), with good calibration and clinical utility.The nomogram based on DECT-derived ECV fraction has the potential as a noninvasive biomarker to predict MSI status in GC patients.","PeriodicalId":507440,"journal":{"name":"Frontiers in Oncology","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141100374","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}

Bulky tumor remains as a challenge to surgery, chemotherapy and conventional radiation therapy. Hence, in efforts to overcome this challenge, we designed a novel therapeutic paradigm via strategy of Stereotactic Central/Core Ablative Radiation Therapy (SCART).), which is based on the principles of SBRT (stereotactic body radiation therapy and spatially fractionated radiation therapy (SFRT). We intend to safely deliver an ablative dose to the core of the tumor and with a low dose at tumor edge. The purpose of the phase 1 study was to determine dose-limiting toxicities (DLT)s and the Maximum Tolerated Dose (MTD) of SCART.We defined a SCART-plan volume inside the tumor, which is proportional to the dimension of tumor. VMAT/Cyberknife technique was adopted. In the current clinical trial; Patients with biopsy proven recurrent or metastatic bulky cancers were enrolled. The five dose levels were 15 Gy X1, 15Gy X3, 18GyX3, 21GyX3 and 24GyX3, while keeping the whole tumor GTV’s border dose at 5Gy each fraction. There was no restriction on concurrent systemic chemotherapy agents.21 patients were enrolled and underwent SCART. All 21 patients have eligible data for study follow-up. Radiotherapy was well tolerated with all treatment completed as scheduled. The dose was escalated for two patients to 24GyX3. No grade 3 or higher toxicity was observed in any of the enrolled patients. The average age of patients was 66 years (range: 14–85) and 13 (62%) patients were male. The median SCART dose was 18Gy (range: 15 - 24). Six out of the 18 patients with data for overall survival (OS) died, and the median time to death was 16.3 months (range: 1 - 25.6). The mean percent change for tumor shrinkage between first visit volumes and post-SCART volumes was 49.5% (SD: 40.89, p-value:0.009).SCART was safely escalated to 24 GyX 3 fractions, which is the maximum Tolerated Dose (MTD) for SCART. This regimen will be used in future phase II trials.
体积巨大的肿瘤仍然是手术、化疗和传统放疗的难题。因此,为了克服这一难题,我们设计了一种新的治疗模式,即立体定向中心/核心消融放射治疗(SCART),它以 SBRT(立体定向体放射治疗和空间分割放射治疗)的原理为基础。我们打算安全地向肿瘤核心部位投放消融剂量,并在肿瘤边缘投放低剂量。1期研究的目的是确定SCART的剂量限制毒性(DLT)和最大耐受剂量(MTD)。我们定义了肿瘤内部的SCART计划体积,该体积与肿瘤的尺寸成正比。我们采用了VMAT/Cyberknife技术。在本次临床试验中,患者均为活检证实的复发性或转移性巨大肿瘤患者。五种剂量水平分别为15Gy X1、15Gy X3、18GyX3、21GyX3和24GyX3,同时保持整个肿瘤GTV边界剂量为每分5Gy。21 名患者入选并接受了 SCART 治疗。21 名患者均接受了 SCART 治疗,所有 21 名患者均有符合条件的随访数据。放疗耐受性良好,所有治疗均按计划完成。有两名患者的剂量增加到24GyX3。所有入组患者均未出现 3 级或以上毒性反应。患者的平均年龄为66岁(14-85岁),男性患者有13名(62%)。SCART 的中位剂量为 18Gy(范围:15 - 24)。18名有总生存期(OS)数据的患者中有6人死亡,中位死亡时间为16.3个月(范围:1 - 25.6)。首次就诊肿瘤体积与SCART治疗后肿瘤体积的平均缩小百分比变化为49.5%(SD:40.89,P值:0.009)。SCART治疗安全升级至24 GyX 3次分次,这是SCART的最大耐受剂量(MTD)。该方案将用于未来的 II 期试验。
