    在非霍奇金淋巴瘤(NHL)的治疗中,多种治疗选择是可用的。改善结果预测对于优化治疗至关重要。代谢活跃肿瘤体积(MATV)已被证明是NHL的预后因素。通常使用基于标准化摄取值(SUV)的半自动阈值方法检索,从18F-氟脱氧葡萄糖正电子发射断层扫描(18F-FDGPET)图像计算。然而,目前尚无NHL的共识方法。这项研究的目的是回顾有关所使用的不同分割方法的文献,并使用内部创建的软件工具评估选定的方法。一个软件工具,开发了MUltipleSUV阈值(MUST)分割器,通过在PET图像上放置种子点来识别肿瘤位置,其次是随后的地区增长。在文献综述的基础上,选择了9种SUV阈值方法并提取了MATV。在68例NHL患者的队列中使用了MUST节段。用配对t检验评估MATV的差异,以及相关性和分布数字。在NHL患者中观察到基于不同分割方法的MATV之间的高变异性和显着差异(p<0.05)。MATV的中位数范围为35至211cc。根据文献没有确定MATV的共识。使用MUST分割器和9种选定的SUV阈值方法,我们证明了MATV的巨大和显着的变化。确定NHL患者的最佳分割方法对于进一步改善毒性预测至关重要,回应,和治疗结果,这可以由MUST-Segmenter促进。
    In the treatment of Non-Hodgkin lymphoma (NHL), multiple therapeutic options are available. Improving outcome predictions are essential to optimize treatment. The metabolic active tumor volume (MATV) has shown to be a prognostic factor in NHL. It is usually retrieved using semi-automated thresholding methods based on standardized uptake values (SUV), calculated from 18F-Fluorodeoxyglucose Positron Emission Tomography (18F-FDG PET) images. However, there is currently no consensus method for NHL. The aim of this study was to review literature on different segmentation methods used, and to evaluate selected methods by using an in house created software tool. A software tool, MUltiple SUV Threshold (MUST)-segmenter was developed where tumor locations are identified by placing seed-points on the PET images, followed by subsequent region growing. Based on a literature review, 9 SUV thresholding methods were selected and MATVs were extracted. The MUST-segmenter was utilized in a cohort of 68 patients with NHL. Differences in MATVs were assessed with paired t-tests, and correlations and distributions figures. High variability and significant differences between the MATVs based on different segmentation methods (p < 0.05) were observed in the NHL patients. Median MATVs ranged from 35 to 211 cc. No consensus for determining MATV is available based on the literature. Using the MUST-segmenter with 9 selected SUV thresholding methods, we demonstrated a large and significant variation in MATVs. Identifying the most optimal segmentation method for patients with NHL is essential to further improve predictions of toxicity, response, and treatment outcomes, which can be facilitated by the MUST-segmenter.

    未经证实:基质靶向治疗对肿瘤免疫抑制的影响在很大程度上尚未被研究。RNA寡核苷酸,STNM01已显示抑制负责肿瘤蛋白聚糖合成和基质重塑的碳水化合物磺基转移酶15(CHST15)。这项I/IIa期研究旨在评估STNM01在不可切除的胰腺导管腺癌(PDAC)患者中的安全性和有效性。
    未经批准:这是一个开放标签,STNM01作为吉西他滨联合nab-紫杉醇难治性PDAC二线治疗的剂量递增研究.一个周期包括三次2周内窥镜超声引导的局部注射STNM01,剂量为250、1,000、2,500或10,000nM,与S-1组合(每天两次80-120mg,每3周14天)。主要结果是剂量-剂量毒性(DLT)的发生率。次要结局包括总生存期(OS),肿瘤反应,肿瘤微环境的变化对免疫组织病理学的影响,和安全性(jRCT2031190055)。
    未经批准:共纳入22例患者,最多重复3个循环;未观察到DLT。中位OS为7.8个月。疾病控制率为77.3%;1例患者显示胰腺和肿瘤引流淋巴结可见病变完全消失。较高的肿瘤CHST15表达与基线时较差的CD3+和CD8+T细胞浸润相关。STNM01导致CHST15的显着减少,并在第1周期结束时与S-1组合的肿瘤浸润性CD3和CD8T细胞增加。CD3+T细胞中更高的倍数增加与更长的OS相关。有8个3级不良事件。
    UNASSIGNED:局部注射STNM01作为联合二线治疗的不可切除PDAC患者的耐受性良好。它通过增强肿瘤微环境中的T细胞浸润来延长存活。
    UNASSIGNED:本研究得到了日本医学研究与发展机构(AMED)的支持。
    UNASSIGNED: The impact of stroma-targeting therapy on tumor immune suppression is largely unexplored. An RNA oligonucleotide, STNM01, has been shown to repress carbohydrate sulfotransferase 15 (CHST15) responsible for tumor proteoglycan synthesis and matrix remodeling. This phase I/IIa study aimed to evaluate the safety and efficacy of STNM01 in patients with unresectable pancreatic ductal adenocarcinoma (PDAC).
    UNASSIGNED: This was an open-label, dose-escalation study of STNM01 as second-line therapy in gemcitabine plus nab-paclitaxel-refractory PDAC. A cycle comprised three 2-weekly endoscopic ultrasound-guided locoregional injections of STNM01 at doses of 250, 1,000, 2,500, or 10,000 nM in combination with S-1 (80-120 mg twice a day for 14 days every 3 weeks). The primary outcome was the incidence of dose-liming toxicity (DLT). The secondary outcomes included overall survival (OS), tumor response, changes in tumor microenvironment on immunohistopathology, and safety (jRCT2031190055).
    UNASSIGNED: A total of 22 patients were enrolled, and 3 cycles were repeated at maximum; no DLT was observed. The median OS was 7.8 months. The disease control rate was 77.3%; 1 patient showed complete disappearance of visible lesions in the pancreas and tumor-draining lymph nodes. Higher tumoral CHST15 expression was associated with poor CD3+ and CD8+ T cell infiltration at baseline. STNM01 led to a significant reduction in CHST15, and increased tumor-infiltrating CD3+ and CD8+ T cells in combination with S-1 at the end of cycle 1. Higher fold increase in CD3+ T cells correlated with longer OS. There were 8 grade 3 adverse events.
    UNASSIGNED: Locoregional injection of STNM01 was well tolerated in patients with unresectable PDAC as combined second-line therapy. It prolonged survival by enhancing T cell infiltration in tumor microenvironment.
    UNASSIGNED: The present study was supported by the Japan Agency for Medical Research and Development (AMED).

    在过去的十年中,随着精确肿瘤学的出现,癌症管理领域发生了变化。免疫检查点抑制剂(ICIs)彻底改变了癌症治疗,并在提高患者生存率方面发挥了重要作用。虽然病人活得更长,用ICIs治疗有时会带来不良反应,其中一些可能是致命的。放射科医生可以通过在重新扫描期间早期识别这些不利影响中的一些来发挥关键作用。本文重点介绍了基于器官系统的常见ICI毒性的影像学特征。
    The past decade has witnessed a change in landscape of cancer management with the advent of precision oncology. Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment and have played an important role in improving patient survival. While the patients are living longer, treatment with ICIs are sometimes associated with adverse effects, some of which could be fatal. Radiologists can play a crucial role by early identification of some of these adverse effects during restaging scans. Our paper focuses on the imaging features of commonly occurring ICI toxicities based on organ system.

    ShcSH2结构域结合蛋白1(SHCBP1),与Src同源物和胶原蛋白同源物(Shc)的SH2结构域特异性结合的蛋白质,参与各种信号转导途径的调节,据报道,这与肿瘤发生和进展有关。然而,病理机制尚未完全研究。因此,本研究旨在全面阐明SHCBP1在多种癌症类型中的潜在功能.SHCBP1在各种肿瘤中的综合分析,包括基因表达,诊断,预后,免疫相关特征,遗传改变,和功能富集,是基于多个数据库和分析工具进行的。SHCBP1在大多数类型的癌症中上调。qRT-PCR结果证实,SHCBP1mRNA在肺腺癌(LUAD)和肝细胞肝癌(LIHC)细胞系中明显上调。基于接收机工作特性(ROC)和生存分析,SHCBP1被认为是潜在的诊断和预后生物标志物。此外,根据SHCBP1表达与免疫细胞浸润的相关性分析,SHCBP1表达与肿瘤免疫和免疫抑制微环境有关,免疫检查点基因,和免疫相关基因(MHC基因,趋化因子,和趋化因子受体)。此外,SHCBP1表达与肿瘤突变负荷(TMB)相关,微卫星不稳定性(MSI),和新抗原。鉴定了泛癌症中SHCBP1突变景观的特征。最后,我们重点研究SHCBP1在LUAD中的临床意义和潜在的生物学作用。我们的研究全面揭示了SHCBP1可以被鉴定为癌症诊断和预后的免疫相关生物标志物。和肿瘤免疫治疗的潜在治疗靶点。
    Shc SH2-domain binding protein 1 (SHCBP1), a protein specific binding to SH2 domain of Src homolog and collagen homolog (Shc), takes part in the regulation of various signal transduction pathways, which has been reported to be associated with tumorigenesis and progression. However, the pathological mechanisms are not completely investigated. Thus, this study aimed to comprehensively elucidate the potential functions of SHCBP1 in multiple cancer types. The comprehensive analyses for SHCBP1 in various tumors, including gene expression, diagnosis, prognosis, immune-related features, genetic alteration, and function enrichment, were conducted based on multiple databases and analysis tools. SHCBP1 was upregulated in most types of cancers. The results of qRT-PCR had confirmed that SHCBP1 mRNA was significantly upregulated in lung adenocarcinoma (LUAD) and liver hepatocellular carcinoma (LIHC) cell lines. Based on the receiver operating characteristic (ROC) and survival analysis, SHCBP1 was considered as a potential diagnostic and prognostic biomarker. Furthermore, SHCBP1 expression was linked with tumor immunity and immunosuppressive microenvironment according to the correlation analysis of SHCBP1 expression with immune cells infiltration, immune checkpoint genes, and immune-related genes (MHC genes, chemokines, and chemokines receptors). Moreover, SHCBP1 expression correlated with tumor mutational burden (TMB), microsatellite instability (MSI), and neoantigens. The feature of SHCBP1 mutational landscape in pan-cancer was identified. Finally, we focused on investigating the clinical significance and the potential biological role of SHCBP1 in LUAD. Our study comprehensively uncovered that SHCBP1 could be identified as an immune-related biomarker for cancer diagnosis and prognosis, and a potential therapeutic target for tumor immunotherapy.

    背景:少发非小细胞肺癌(NSCLC)患者的治疗仍存在争议。有有限的数据支持立体定向消融放射治疗(SABR)结合正在进行的系统治疗的策略。我们的目标是评估这种方法与标准治疗在治疗寡进行性NSCLC中的益处。
    方法:这项II期研究将纳入68名寡进行性NSCLC患者,定义为1-5个进行性颅外病变≤5cm,涉及≤3个器官。接受积极全身治疗的患者(化疗,免疫疗法,靶向治疗或联合治疗)将以1:1的比例随机分配,以继续其目前的全身治疗与SABR联合治疗所有病变或标准治疗(切换到下一行治疗,继续相同的治疗或观察)。共同主要终点是无进展生存期(PFS)和总生存期(OS)。次要终点包括下一次全身治疗的时间,患者报告的生活质量,成本效益以及翻译分析,以表征外周血中的适应性免疫和免疫原性细胞死亡标志物。
    结论:需要仔细检查疗效,在少进性疾病背景下SABR的安全性和生活质量影响。本研究将提供更高水平的关于SABR在寡进行性NSCLC中的作用的随机证据。
    BACKGROUND: Management of Non-Small Cell Lung Cancer (NSCLC) patients with oligoprogression remains controversial. There is limited data to support the strategy of Stereotactic Ablative Radiotherapy (SABR) targeting the oligoprogressive disease in combination with ongoing systemic treatment. We aim to assess the benefit of this approach compared to standard of care in the treatment of oligoprogressive NSCLC.
    METHODS: This phase II study will enroll 68 patients with oligoprogressive NSCLC, defined as 1-5 progressive extracranial lesions ≤5 cm involving ≤3 organs. Patients on active systemic therapy (chemotherapy, immunotherapy, targeted therapy or a combination) will be randomized 1:1 to either continue their current systemic therapy in combination with SABR to all lesions or the standard of care (switch to the next line of treatment, continue same treatment or observation). The co-primary endpoints are progression-free survival (PFS) and overall survival (OS). Secondary endpoints include time to next systemic treatment, patient-reported quality of life, cost effectiveness as well as translational analysis to characterize both adaptive immunity and immunogenic cell death markers in the peripheral blood.
    CONCLUSIONS: There is an unmet need to carefully examine the efficacy, safety and quality of life impact of SABR in the context of oligoprogressive disease. The present study will provide higher level randomized evidence on the role of SABR in oligoprogressive NSCLC.

    子宫颈腺癌在怀孕期间的发病率非常罕见,因此对其管理没有共识。这里,我们报告了2例妊娠时诊断的子宫颈腺癌。在我们的第一个案例中,一名因不明意义的非典型腺细胞而接受阴道镜检查的患者随后在锥形活检中被诊断为高分化的宫颈内膜腺癌.就在锥形活检之前,偶然发现她怀孕前三个月流产。患者随后接受了根治性子宫切除术和双侧前哨淋巴结清扫术。最终病理显示为1B1期(FIGO2009)宫颈高分化腺癌。有趣的是,肿瘤的雌激素受体呈阳性,这对宫颈腺癌来说是不寻常的。在我们的第二个案例中,一个有花梗的病人,31周时外生性宫颈肿瘤伴自限性产前出血。在MRI上测量原发病灶直径为52mm,在患者择期再次剖宫产时在底部截肢。最终病理显示为IB2期(FIGO2009)宫颈粘液腺癌。患者随后在初次就诊后17周接受了根治性子宫切除术和双侧盆腔淋巴结清扫术。侵入深度为2.2mm,仅限于宫颈壁的内三分之一,手术标本中无淋巴管间隙侵犯。手术切缘,parametria,淋巴结均未见腺癌。该肿瘤也被发现是雌激素受体/孕激素受体(ER/PR)阳性,再次不寻常的宫颈腺癌。P16强阳性,人乳头瘤病毒18的HPVDNA研究也呈阳性。患者接受骨盆辅助外照射放疗,目前仍处于缓解状态。
    The incidence of adenocarcinoma of the cervix in pregnancy is exceptionally rare, and thus there is no consensus on its management. Here, we report two cases of adenocarcinoma of the cervix diagnosed in the context of pregnancy. In our first case, a patient referred to colposcopy for atypical glandular cells of undetermined significance was subsequently diagnosed with well differentiated endocervical adenocarcinoma on cone biopsy. Just prior to the cone biopsy, she was incidentally found to have a first trimester pregnancy loss. The patient subsequently underwent a radical hysterectomy and bilateral sentinel lymph node dissection. Final pathology revealed a stage 1B1 (FIGO 2009) well differentiated adenocarcinoma of the cervix. Interestingly, the tumour was positive for estrogen receptor, which is unusual for cervical adenocarcinoma. In our second case, a patient presented with a pedunculated, exophytic cervical neoplasm at 31 weeks GA with self-limiting antepartum hemorrhage. The primary lesion measured 52 mm in diameter on MRI and was amputated at the base during the patient\'s elective repeat cesarean section. Final pathology revealed a stage IB2 (FIGO 2009) mucinous adenocarcinoma of the cervix. The patient subsequently underwent a radical hysterectomy and bilateral pelvic lymph node dissection 17 weeks after initial presentation. The depth of invasion was 2.2 mm, restricted to the inner third of the cervical wall, and there was no lymphovascular space invasion in the surgical specimen. Surgical margins, parametria, and lymph nodes were all negative for adenocarcinoma. This tumour was also found to be estrogen receptor/progesterone receptor (ER/PR) positive, again unusual for cervical adenocarcinoma. P16 was strongly positive and HPV DNA studies were also positive for human papilloma virus 18. The patient received adjuvant external beam radiotherapy to the pelvis and currently remains in remission.

    作为洞穴最重要的组成部分之一,caveolin-1参与caveolae介导的胞吞和转胞吞途径,并在调节细胞膜胆固醇稳态和介导信号转导中起作用。近年来,caveolin-1在肿瘤微环境中的表达水平与肿瘤治疗预后效果及药物治疗耐药的关系也被广泛探讨。此外,caveolin-1和纳米药物之间的相互作用是双向的。Caveolin-1可以确定特定纳米药物的细胞内生物产物,防止溶酶体降解,并促进它们通过胞吞作用渗透到肿瘤的更深部位;而一些纳米载体也可能影响肿瘤细胞中的caveolin-1水平,从而改变细胞的某些生物物理功能。本文综述了caveolin-1在肿瘤预后中的作用。化疗耐药,抗体药物敏感性,和纳米药物递送,为caveolin-1在纳米给药系统中的进一步应用提供参考。
    As one of the most important components of caveolae, caveolin-1 is involved in caveolae-mediated endocytosis and transcytosis pathways, and also plays a role in regulating the cell membrane cholesterol homeostasis and mediating signal transduction. In recent years, the relationship between the expression level of caveolin-1 in the tumor microenvironment and the prognostic effect of tumor treatment and drug treatment resistance has also been widely explored. In addition, the interplay between caveolin-1 and nano-drugs is bidirectional. Caveolin-1 could determine the intracellular biofate of specific nano-drugs, preventing from lysosomal degradation, and facilitate them penetrate into deeper site of tumors by transcytosis; while some nanocarriers could also affect caveolin-1 levels in tumor cells, thereby changing certain biophysical function of cells. This article reviews the role of caveolin-1 in tumor prognosis, chemotherapeutic drug resistance, antibody drug sensitivity, and nano-drug delivery, providing a reference for the further application of caveolin-1 in nano-drug delivery systems.

    UNASSIGNED: Conventional osteosarcoma is an orphan disease. Current treatment approaches include combining a three drug chemotherapy schedule and surgery. The 3- and 5-year event-free survival (EFS) in localized disease is roughly 65 and 60%, respectively. The registration study of mifamurtide reported survival benefit, but some methodological controversies have been insufficient for FDA market authorization in contrast to EMA.
    UNASSIGNED: prospective single centre survival analysis of a mifamurtide addition to conventional therapy in 23 patients over a 5.5 year enrolment period is reported and compared to a historical control of 26 patient with localized disease. Bias arising from observational methodology was addressed using Landmark analysis and time-dependent Cox models. Blood count dynamics were analysed during the treatment.
    UNASSIGNED: The adverse event profile was as expected with no dose limiting toxicities. There were no local relapses observed, one patient died in the first complete remission due to doxorubicin cardiotoxicity, one patient had pulmonary metastatic relapse. The observed 3- and 5-year EFS was 87.4% (CI 72.4-100%) and 87.4% (CI 72.4-100%), progression free survival (PFS) was 92.9% (CI 80.3-100%) and 92.9% (CI 80.3-100%), overall survival was 94.1% (CI 83.6-100) and 80.7% (CI 58.3-100), respectively. Comparison to the historical control showed statistically significant better PFS for mifamurtide patients (Landmark analysis; p = 0.044). Risk of progression was 5-times lower for the mifamurtide group (Cox model; HR 0.21, p = 0.136). Only subtle differences in lymphocyte counts were observed across treatment.
    UNASSIGNED: the PFS benefit of mifamurtide is reported herein. The addition of mifamurtide could be considered as a best treatment option for localized osteosarcoma.
