Background: Induction therapy followed by surgery is recommended as an alternative treatment strategy for locally advanced non-small cell lung cancer (NSCLC). Patients who achieve pathologic response after induction therapy have better outcomes than non-responders; therefore, therapeutic response must be evaluated. Recently, new approaches for monitoring therapeutic responses, which are based on 18F‐Fluorodeoxyglucose positron emission tomography (FDG‐PET), have been developed. In this study, we evaluated the predictive value of Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST), which uses standardized uptake values corrected for lean body mass (SUL) and total lesion glycolysis (TLG). Methods: A total of 130 patients in the Setouchi Lung Cancer Group who underwent FDG-PET imaging before and after induction therapy prior to a planned surgical resection for NSCLC between 2007 and 2016 were studied retrospectively. The pathologic responses of the primary lung tumors and metastatic lymph nodes were compared with their responses based on evaluation using PERCIST. Results: Postoperative pathologic studies revealed pathologic complete response (pCR) in 42 (32.3%) patients. PERCIST was significantly correlated with pathologic response (p < 0.001). The sensitivity, specificity, and accuracy of PERCIST for predicting pCR were 16.7% (7/42), 88.6% (78/88), and 65.4% (85/130), respectively. Patients with pCR had significantly higher reduction rates in SULpeak for both primary lung tumors and metastatic lymph nodes and TLG for primary tumors than non-responders. In a multivariate Cox regression analysis, tumor site in upper lobes, reduction rate of TLG in primary tumor, and pathologic N0 were independent predictors of favorable recurrence-free survival (RFS). Conclusion: Our study suggested that PERCIST, especially the rate of TLG reduction rate, are useful to predict the pathological response and prognosis after induction therapy. Although improvement is necessary, PERCIST can be a promising method of the post-induction status in lung cancer. Further research is needed to confirm our findings.

Abstract: Biliary tract cancer (BTC) represents a challenging malignancy characterized by aggressive behavior, high relapse rates, and poor prognosis. In recent years, immunotherapy has revolutionized the treatment landscape for various cancers, but its efficacy in BTC remains limited. This article provides a comprehensive overview of the advances in preclinical and clinical studies of immunotherapy for BTC. We explore the potential of immune checkpoint inhibitors in reshaping the management of BTC. Despite disappointing results thus far, ongoing clinical trials are investigating the combination of immunotherapy with other treatment modalities. Furthermore, research on the tumor microenvironment has unveiled novel targets for immunotherapeutic interventions. By understanding the current state of immunotherapy in BTC and highlighting future directions, this article aims to fuel further exploration and ultimately improve patient outcomes in this challenging disease.

<strong>Objective:</strong> Serum pepsinogen (PG) is a good indicator of atrophic changes in the gastric mucosa. Gastric mucosal atrophy is a high-risk factor for gastric cancer. Serological testing for PG combined with endoscopy can help to improve gastric cancer screening. In this study, we established the reference ranges of serum PG-I, PG-II, and the PG-I/II ratio (PGR) in the Chinese population by chemiluminescence immunoassay (CLIA) and enzyme-linked immunosorbent assay (ELISA). Besides, in the real world, doctors are often confused by the results of different testing platforms. Thus, a comparison of methods CLIA and ELISA was performed.<br/><strong>Methods:</strong> 2904 individuals were enrolled from six regions in China as part of the Chinese Adult Digestive Diseases Surveillance (2016) program. The individuals completed questionnaires and volunteered to undergo examinations, including gastroscopy, urea breath test, abdominal ultrasound examination and routine serologic tests. Serum was collected to measure PGs (including PG-I, PG-II and PGR) by CLIA and ELISA. Participants who were found obvious abnormalities or absent from the examinations were excluded. Ultimately, 747 healthy individuals were enrolled in this study. The Kolmogorov–Smirnov test was used to assess the distribution of variables. The Kruskal–Wallis <em>H</em> or Mann–Whitney <em>U</em>-tests were used to compare different sex, age, and geographical groups. The 95% reference ranges of PGs obtained by the two methods were established according to document CLSI-EP28-A3, with covariates of sex, age, and region. Spearman correlation analysis, linear regression analysis and allowable total error (ATE) zone analysis were utilized for comparing the two methods.<br/><strong>Results:</strong> On overall, the 95% reference ranges of PG-I, PG-II, and PGR measured by CLIA were 23.00– 110.64 ng/mL, 2.50– 19.13 ng/mL, and 3.87– 13.30, respectively. Meanwhile, the reference ranges of PG-I, PG-II, and PGR measured by ELISA were 36.93– 205.06 ng/mL, 1.65– 17.96 ng/mL, and 7.50– 33.60, respectively. Both PG-I and PG-II levels measured by the two platforms were found to be influenced by sex and age. PGR measured by CLIA was influenced by age but not by sex, while PGR measured by ELISA was not affected by either age or sex. Regional factors did not significantly impact the PG results, except for PG-I detected by ELISA. Ultimately, reference ranges for PGs were established based on age and sex stratification. Additionally, the Spearman correlation analysis revealed that the correlation coefficients for PG-I, PG-II, and PGR detected by the two methods were 0.899, 0.887, and 0.777, respectively, indicating a strong correlation between the two methods.

Abstract: The treatment landscape for advanced and metastatic melanoma has drastically changed in recent years, with the advent of novel therapeutic options such as immune checkpoint inhibitors and targeted therapies offering remarkable efficacy and significantly improved patient outcomes compared to traditional approaches. Approximately 50% of melanomas harbor activating BRAF mutations, with over 90% resulting in BRAF V600E. Tumors treated with BRAF inhibitor monotherapy have a high rate of developing resistance within six months. Combination therapy with MEK inhibitors helped to mitigate this treatment resistance and led to improved outcomes. Due to the up-regulation of PD-1/PD-L1 receptors in tumors treated with BRAF/MEK inhibitor therapy, further studies included a third combination agent, anti-PD-1/PD-L1 inhibitors. This triple combination therapy may have superior efficacy and a manageable safety profile when compared with single or double agent therapy regimens.
Plain Language Summary: Effective treatment of advanced and metastatic melanoma can be challenging. Newer treatment methods for patients with BRAF-mutated tumors include a combination of drugs with different complementary mechanisms. These drugs include BRAF-inhibitors, MEK-inhibitors, and PD-1/PD-L1 inhibitors. When these three medications are used in combination, patients may have better response rates and survival outcomes, when compared to using just one or two of these medications together. Toxicity rates are higher with a triple-medication regimen, so careful patient selection is important to consider.

Abstract: The rising global morbidity and mortality rates of non-small cell lung cancer (NSCLC) underscore the urgent need for more effective treatments. Current therapeutic modalities—including surgery, radiotherapy, chemotherapy, and targeted therapy—face several limitations. Recently, Astragalus membranaceus, a traditional Chinese medicine (TCM), has captured significant attention due to its broad pharmacological properties, such as immune regulation, anti-inflammatory effects, and the modulation of reactive oxygen species (ROS) and enzyme activities. This review delivers a comprehensive summary of the most recent advancements and ongoing applications of Astragalus membranaceus in NSCLC treatment, underlining its potential for integration into existing treatment protocols. It also highlights essential areas for future research, including the elucidation of its molecular mechanisms, optimization of dosage and administration, and evaluation of its efficacy and safety alongside standard therapies, all of which could potentially improve therapeutic outcomes for NSCLC patients.

Background: Gastric cancer (GC) is a highly phenotypically heterogeneous disease and is caused by a combination of factors. Retinol binding protein 4 (RBP4) is a member of a family of lipid transport proteins that are involved in the transport of substances between cells and play a crucial role in a variety of cancers. However, the expression and role of RBP4 in GC remain unknown. Methods: In this study, we explored the expression, prognostic significance, immune microenvironment, drug responsiveness and function of associated signaling pathways of RBP4 in GC using web-based bioinformatics tools. Immunohistochemistry and real-time quantitative PCR were utilized to analyze the tissue and cell expression levels of RBP4. CCK-8, colony formation, EDU incorporation, wound healing and transwell assays were applied to demonstrate the effect of RBP4 on GC cell function. Flow cytometric detection of apoptosis after RBP4 knockdown. Nude mice xenograft model elucidates the role of RBP4 for GC in vivo. Related proteins of the RAS signaling pathway were analyzed by employing Western blot assays. Results: RBP4 is highly expressed in GC. RBP4 is closely associated with patient survival and sensitivity to a wide range of antitumor agents. Knockdown of RBP4 promoted apoptosis and inhibited cell proliferation, invasion and migration. RBP4 promotes GC tumorigenesis in vivo. Finally, RBP4 modulates the RAS/RAF/ERK axis. Conclusion: RBP4 may promote gastric carcinogenesis and development through the RAS/RAF/ERK axis and is expected to be a novel target for GC treatment.

Objective: To explore the effectiveness of prostate biopsy density in predicting prostate cancer under cognitive and systematic biopsy mode in multi-parametric magnetic resonance imaging (mpMRI). Methods: A retrospective analysis was conducted on clinical data of 204 patients who were suspected of having prostate cancer with prostate-specific antigen (PSA) levels less than 50 ng mL− 1 and underwent cognitive and systematic biopsy through the perineal approach in our hospital from 2022 to 2023. Univariate and multivariate logistic regression analyses were used to evaluate the odds ratios of prostate biopsy density and relevant clinical indicators. Logistic regression analysis was performed to establish a predictive model combining indicators with predictive value. The predictive value of each indicator and the new model was evaluated using receiver operating characteristic (ROC) curves and the area under the curve (AUC). Results: The detection rate of prostate cancer in the study population was 32.35%. Multivariate analysis showed that age, PSAD, PI-RADS 2.1 score, and prostate biopsy density were independent predictors of prostate cancer. The ROC curve analysis revealed an AUC of 0.707 (95% CI 0.625– 0.790) for biopsy density, with a cutoff value of approximately 0.22 needle mL− 1. The best predictive model consisted of age, PSAD, PI-RADS 2.1 score, and biopsy density, with an AUC of 0.857. Conclusion: Biopsy density is associated with the detection of prostate cancer, with a critical value of 0.22 needle mL− 1. Combining biopsy density with other clinical indicators can significantly improve the ability to predict prostate cancer and avoid unnecessary prostate biopsy cores.

Purpose: This retrospective cohort study assessed semen and testicular tissue quality from adult and adolescent cancer patients who had samples cryopreserved in the Cryobank of Charité-Universitätsmedizin before and/or after cancer treatment. Methods and Materials: Medical and cryopreservation data for all samples stored between 03/2004 and 05/2019 were collected retrospectively. Results: We included information on 601 samples cryopreserved from 506 cancer patients for whom oncologic treatment data were available. The majority of the samples were cryopreserved prior to cancer treatment (460/600, 77%, median 5 days before treatment). Semen quality had a predisposed reduction in those collected from adolescents with testicular and/or hematological malignancies. Analyses of the 140 (23%) samples cryopreserved after treatment initiation (median of 84 days) revealed decreased median concentration and motility following high gonadotoxic-risk treatment. Rate of oligoasthenozoospermia was comparable in samples collected prior to treatment with those provided during follow-up spermiograms within 1 year after treatment initiation (45.5% vs 45.5%). However, an increase was seen in samples collected 1– 2 (9.1% to 90.9%) and 2– 3 (50.0% to 100.0%) years after treatment initiation. Conclusion: Cancer diagnosis and treatment may impair spermatogenesis; therefore, patient counseling prior to cancer treatment by an oncologist and/or fertility specialist is crucial.

<strong>Purpose:</strong> Immune checkpoint inhibitors (CPIs) have been widely adopted in a number of early and advanced malignancies. Histone deacetylase inhibitors (HDACis) and alkylating agents (AAs) have been suggested to potentiate the actions of CPIs on tumor cells. We conducted a comprehensive literature review to explore the potential synergistic activity between CPIs, AAs, and HDACis.<br/><strong>Patients and Methods:</strong> Clinical and non-clinical studies describing outcomes in patients with cancer receiving CPIs and either concomitant or sequential (pre- or post-CPI) AAs or HDACis were identified in PubMed using pre-defined search strings. Manual searches of key oncology congresses were similarly performed. All relevant articles and abstracts were manually screened for relevance, classified according to the specific anticancer agents used (CPIs, AAs, or HDACis), tumor entity, and whether treatment was concomitant or sequential.<br/><strong>Results:</strong> Overall, 227 unique clinical studies across a range of tumor types, both solid tumors and hematological malignancies, were identified. One hundred and fifty-nine publications on Phase I and II clinical studies together with 41 publications on Phase III studies were examined. The most commonly investigated tumor types were melanoma, triple-negative breast cancer, non-small cell lung cancer, and Hodgkin lymphoma. The randomized clinical studies identified, all of which reported on the combination of a CPI with an AA, demonstrated superior outcomes in the combination arm compared with CPI or AA monotherapy. Similarly, combination therapy with CPIs and HDACis demonstrated promising activity.<br/><strong>Conclusion:</strong> Sequential or concomitant administration of a CPI with an AA or an HDACi may improve outcomes for patients with a range of tumor types. There is a rationale to support further investigation into the potential for synergy between CPIs, alkylating agents and/or HDACis in both the non-clinical and clinical settings.<br/><br/><strong>Plain Language Summary:</strong> People being treated for cancer will often receive more than one drug at a time, and the concept of combining cancer drugs is frequently investigated as a potential opportunity to improve outcomes for patients. We reviewed the published literature for clinical trials and work undertaken in laboratories to explore whether combining targeted agents that stop cancer cells from multiplying (known as checkpoint inhibitors) with traditional chemotherapy that kills cancer cells could be a useful approach. We looked at evidence in publications where checkpoint inhibitors were used at the same time as chemotherapy, or given immediately before or after chemotherapy. The most important evidence came from clinical trials where outcomes for patients receiving combinations of treatment were directly compared with those from patients receiving a single treatment.

目的：免疫检查点抑制剂（CPIs）已被广泛用于一些早期和晚期恶性肿瘤。有人认为组蛋白去乙酰化酶抑制剂（HDACis）和烷化剂（AAs）能增强CPIs对肿瘤细胞的作用。我们进行了全面的文献综述，以探索 CPIs、AAs 和 HDACis 之间潜在的协同活性：使用预先定义的搜索字符串，在 PubMed 上查找描述癌症患者接受 CPIs 和同时或先后（CPI 之前或之后）接受 AAs 或 HDACis 治疗的临床和非临床研究。对主要肿瘤学大会也进行了类似的人工检索。人工筛选所有相关文章和摘要的相关性，并根据使用的特定抗癌药物（CPI、AA 或 HDACis）、肿瘤实体以及治疗是同时进行还是连续进行进行进行分类：总体而言，共发现了 227 项独特的临床研究，涉及多种肿瘤类型，包括实体瘤和血液恶性肿瘤。其中 159 篇发表于 I 期和 II 期临床研究，41 篇发表于 III 期研究。最常研究的肿瘤类型是黑色素瘤、三阴性乳腺癌、非小细胞肺癌和霍奇金淋巴瘤。已确定的随机临床研究均报告了 CPI 与 AA 的联合治疗，结果显示联合治疗组的疗效优于 CPI 或 AA 单药治疗组。同样，CPI 与 HDACis 的联合疗法也显示出良好的活性：结论：CPI 与 AA 或 HDACi 相继或同时给药可改善各种肿瘤类型患者的预后。有理由支持在非临床和临床环境中进一步研究 CPIs、烷化剂和/或 HDACis 之间的潜在协同作用。我们回顾了已发表的临床试验文献和实验室工作，以探讨将阻止癌细胞繁殖的靶向药物（称为检查点抑制剂）与杀死癌细胞的传统化疗相结合是否是一种有用的方法。我们研究了在化疗的同时使用检查点抑制剂或在化疗前后立即使用检查点抑制剂的出版物中的证据。最重要的证据来自临床试验，在这些试验中，接受联合治疗的患者的疗效与接受单一治疗的患者的疗效进行了直接比较。这些研究显示，与接受单一疗法的患者相比，接受联合抗癌药物治疗的患者疗效更佳。我们还发现有证据表明，加入另一类抗癌药物（组蛋白去乙酰化酶抑制剂）可能会使肿瘤对检查点抑制剂敏感。这些发现为研究烷化剂和/或组蛋白去乙酰化酶抑制剂与检查点抑制剂联合应用提供了理论依据。 关键词：组蛋白去乙酰化酶抑制剂；检查点抑制剂；烷化剂；协同作用；血液恶性肿瘤；实体瘤

Background: Prior to the Food and Drug Administration approval of cemiplimab in 2018, the median overall survival (OS) for adult patients with advanced CSCC receiving systemic therapy was approximately 8 to 15 months. Limited real-world data are available on cemiplimab for this indication in the US. Patients and Methods: This retrospective cohort study included US patients with advanced CSCC initiating cemiplimab monotherapy in a real-world database (2018– 2021). A clinical trial–like sub-cohort was identified using select criteria. Time to treatment discontinuation (TTD), time to next treatment (TTNT), and OS were estimated using Kaplan–Meier methods. Cox proportional hazard models were used to examine prognostic factors associated with OS in the main cohort. Results: The main cohort included 622 patients (n = 240 in the trial-like cohort). In the main cohort, the median age was 78 years, 77.8% were male, 21.4% were immunocompromised/immunosuppressed, and 63.8% had metastatic CSCC. Median (95% CI) TTD and TTNT were 8.0 (6.6– 9.0) months and 16.4 (13.3– 21.0) months, respectively, in the main cohort. Median (95% CI) OS was 24.8 (21.8– 29.1) months in the main cohort (not reached in the trial-like cohort). In multivariable analyses, age < 60 years (hazard ratio [HR], 0.37), Eastern Cooperative Oncology Group performance status < 3– 4 (HR range, 0.13– 0.57), and primary CSCC location in the head and neck only versus extremities only (HR, 0.59) were associated with better OS. Similar OS was observed between patients who had immunosuppressing/immunocompromising conditions and those without. Conclusion: These findings confirm the effectiveness of cemiplimab among a heterogenous, real-world advanced CSCC patient population and substantiate the efficacy of cemiplimab observed in clinical trials.
