Background: The Scottish Inflammatory Prognostic Score (SIPS), an innovative scoring system, has emerged as a promising biomarker for predicting patient outcomes following cancer therapy. This study aimed to evaluate the value of SIPS as a prognostic indicator following hepatectomy in patients with hepatocellular carcinoma (HCC).
Methods: This retrospective study included 693 HCC patients who underwent hepatectomy. Survival outcomes were compared between propensity score-matched groups. Independent prognostic factors were identified through Cox regression analysis. Additionally, both traditional Cox proportional hazards models and machine learning models based on the SIPS were developed and validated.
Results: A total of 693 HCC patients who underwent hepatectomy were included, with 102 in the high SIPS group and 591 in the low SIPS group. Following propensity score matching (1:3 ratio), both groups achieved balance, with 82 patients in the high SIPS group and 240 patients in the low SIPS group. The low SIPS group demonstrated significantly superior recurrence-free survival (RFS) (25 months vs. 21 months; P < 0.001) and overall survival (OS) (69 months vs. 58 months; P < 0.001) compared to the high SIPS group. Multivariable analysis identified SIPS as an independent adverse factor affecting both RFS and OS. The calibration curve for overall patient survival diagnosis displayed excellent predictive accuracy. Traditional COX prognostic models and machine learning models incorporating SIPS demonstrated excellent performance both the training and validation set.
Conclusion: This study confirms the prognostic significance of SIPS in post-hepatectomy HCC patients, providing a practical tool for risk stratification and clinical decision-making. Further research and validation are needed to consolidate its role in prognostic assessment.

Background: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) and EGFR-TKI combination treatments have become the standard first-line treatments for EGFR-mutated non-small cell lung cancer (NSCLC) patients. However, the best option has yet to be determined. This study compares the efficacy and safety of various first-line EGFR-TKI monotherapies and combination treatments for advanced EGFR-mutated NSCLC.
Methods: We searched PubMed, Embase, the Cochrane Central Register of Controlled Clinical Trials databases, and several international conferences to identify randomized controlled trials reporting on first-line EGFR-TKI treatments for patients with advanced EGFR-mutated NSCLC. The study quality was assessed using the revised tool for risk of bias in randomized trials. The efficacy and safety outcomes of the included treatments were compared by network meta-analysis based on a frequentist approach.
Results: We identified 26 trials (8,359 patients) investigating 14 treatment groups, including first, second, and third-generation EGFR-TKIs and their combination treatments. Osimertinib plus chemotherapy and lazertinib plus amivantamab showed the highest efficacy in improving progression-free survival. New third-generation EGFR-TKIs demonstrated comparable efficacy to osimertinib alone but did not surpass it. Subgroup analyses revealed slight variation in treatment efficacy based on mutation types and patient demographics. Combination treatments were associated with a higher incidence of adverse events.
Conclusion: These results reveal that osimertinib plus chemotherapy and lazertinib plus amivantamab are superior first-line options for patients with advanced EGFR-mutated NSCLC. However, these combinations are associated with higher adverse event rates.
背景:表皮生长因子受体(EGFR)酪氨酸激酶抑制剂(TKIs)和EGFR-TKI联合疗法已成为EGFR突变非小细胞肺癌(NSCLC)患者的标准一线治疗方法。然而,最佳方案尚未确定。本研究比较了各种一线EGFR-TKI单药治疗和联合治疗晚期EGFR突变NSCLC的疗效和安全性:我们检索了PubMed、Embase、Cochrane Central Register of Controlled Clinical Trials数据库和一些国际会议,以确定报道晚期EGFR突变NSCLC患者一线EGFR-TKI治疗的随机对照试验。研究质量采用随机试验偏倚风险修订工具进行评估。通过基于频数主义方法的网络荟萃分析比较了所纳入疗法的疗效和安全性结果:我们确定了26项试验(8359名患者),调查了14个治疗组,包括第一代、第二代和第三代表皮生长因子受体-TKIs及其联合治疗。奥希替尼联合化疗和拉唑替尼联合阿米万他单抗在改善无进展生存期方面疗效最佳。新型第三代表皮生长因子受体-TKIs的疗效与奥希替尼单药相当,但并未超越奥希替尼。亚组分析显示,根据突变类型和患者人口统计学特征,治疗效果略有不同。联合治疗的不良反应发生率较高:这些结果表明,奥西替尼加化疗和拉唑替尼加阿米万他单抗是晚期表皮生长因子受体突变NSCLC患者的一线选择。然而,这些组合的不良事件发生率较高。

Background: Wilms tumor (WT) is the most common malignant renal tumor in children. This study investigated the clinical features, pathological findings, and outcomes of children with malignant renal tumors in Southern Iran. Factors associated with recurrence and mortality were assessed.
Methods: Electronic files of children with malignant renal tumors from 2009 to 2023 were reviewed. The 5-year overall survival (OS) and event-free survival (EFS) were reported.
Results: Eighty-three patients (44 males) with a median age of 40 months (range: 3-122) were included. WT was the most common pathological variant (94%). Anaplasia was found in 17.3% of patients. Upfront chemotherapy followed by nephrectomy was performed in 54.2% of the patients. Ten patients (12%) experienced relapse, and five patients (6%) died during the 14-year follow-up. The 5-year OS and EFS were 90.75% (95% CI, 78.64-96.16%) and 81.9% (95% CI, 70.10-89.38%), respectively, and were comparable between the two treatment strategies (upfront chemotherapy vs. upfront nephrectomy). Metastasis and residual disease were associated with relapse, whereas tumor recurrence was the only predictive factor of survival.
Conclusion: WT is a curable disease with excellent outcomes if diagnosed and treated promptly. The timing of nephrectomy does not affect OS and EFS. Patients with low-stage tumors and those with complete surgical excision are at a lower risk of tumor recurrence. Relapse is the primary risk factor for death.

Background: Pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) is a treatment for preventing febrile neutropenia (FN) in patients with early breast cancer. However, the optimal injection timing of PEG-rhG-CSF after chemotherapy is obscure. The trial was designed to explore the best administration timing of PEG-rhG-CSF when breast cancer patients could benefit most.
Methods: Patients with early breast cancer were randomly assigned to receive a preventive injection on the 7th or 3rd day following chemotherapy. The experimental group (n = 80) received PEG-rhG-CSF treatment on day 7 after chemotherapy, whereas the control group (n = 80) received it on day 3. The occurrence of grades 3-4 neutropenia and FN in the first cycle was the primary endpoint. The secondary endpoint was the frequency of PEG-rhG-CSF dose reduction.
Results: In comparison to the control group, the experimental group exhibited higher white blood cell count (WBC) and absolute neutrophil count (ANC) on the 9th and 13th days following chemotherapy (P < 0.05). Additionally, the incidence of grade 3-4 neutropenia was significantly lower in the experimental group (P = 0.038). Furthermore, a greater proportion of patients in the experimental group met the criteria for reducing the PEG-rhG-CSF dose compared to the control group (69.74% vs. 35.06%, P < 0.001).
Conclusions: In comparison with PEG-rhG-CSF injection on day 3 after chemotherapy, the incidence of grade 3-4 myelosuppression is lower, and the safety is more manageable after the injection on day 7. This approach potentially allows for a wider adoption of PEG-rhG-CSF dose reduction, leading to a consequential decrease in overall medical costs for patients.

Background: In ovarian cancer frequently reported side effects are muscle wasting and malnutrition, leading to frailty, decreased health-related quality of life (HRQoL), and cancer-related fatigue (CRF). Both often begin during first-line chemotherapy and develop progressively into a refractory state, if left untreated.
Method: Primary objective is to evaluate effectiveness of a newly developed app-based exercise and nutrition program under non-standardized conditions of clinical routine. We hypothize that patients who receive an individually tailored exercise and nutrition program for six months will have improved physical performance compared to patients who receive usual care. This is a multicenter randomized controlled open-label trial comparing an intervention group receiving a six-month exercise and nutrition intervention and a control group receiving usual care. Primary endpoint is the change in 6-Minute Walk Test (6MWT) from baseline to T2 (26 weeks after baseline) as a measure of physical functioning. Secondary endpoints include patients' utilization and adherence to the nutrition program (MEDAS), their malnutrition risk (NRS2002), as well as patients' HRQoL (see Table 1). Using the two-sample t-test with a two-sided type I error of 5% and 80% power, a medium effect size of Cohen's d = 0.50 can be demonstrated with a minimum of 128 participants (64 per group). With a conservatively estimated dropout rate of 30%, 182 patients will be recruited. Patients who are included must be over 18 years of age, be diagnosed with ovarian cancer, cancer of fallopian tubes, or peritoneal cancer, FIGO stages II-IV, receive surgery and chemotherapy (adjuvant or neoadjuvant). Exclusion criteria are an ECOG status greater than 2, inadequate proficiency in German, or physical or mental impairments hindering the implementation of the program or execution of study procedures.
Discussion: In case of success, the project contributes in the long term to (i) improving medical care (diagnosis, psychoeducation, patient orientation, and empowerment), (ii) reducing the burden of disease and promoting physical autonomy for patients, and (iii) being incorporated into relevant guidelines.
Trial registration: The study was registered at ClinicalTrials.gov (NCT06250686).

Background: This study aims to investigate a novel instrument OM-100 with low-frequency magnetic fields (LFMFs) for its potential applicability in the treatment of liver cancer.
Methods: Liver cancer cell lines (HepG2 and Huh7) and normal liver cell line THLE-2 were exposed to OM-100 at LFMFs of 0, 10, 25, 50, and 100 kHz for 2 h in the morning, noon, and evening, respectively. The effects of LFMF on cell viability, apoptosis, migration, and invasion capabilities were examined. Additionally, impacts of LFMF on ROS production was assessed. In vivo studies were conducted to examine the safety profile of OM-100 and its effects on tumor growth.
Results: In vitro, OM-100 reduced the viability of liver cancer cells, increased cell apoptosis, and inhibited cell migration and invasion abilities in a frequency-dependent manner (P < 0.05). In vivo, OM-100 significantly slowed down tumor growth and promoted apoptosis in liver tumors (P < 0.05). Moreover, OM-100 rarely affected the viability of normal liver cells, as well as the health of normal mice. Finally, we further found that OM-100 significantly increased the production of ROS in liver cancer cells (P < 0.05), a key factor in inducing autophagy, which is very important for the progression of liver cancer.
Conclusion: Our findings reveal the safety of OM-100 and its frequency at 100 kHz significantly inhibits liver cancer progression.

Objective: To compare the performance of [18F]FDG and [18F]FAPI-04 in PET/CT evaluation for liver cancer lesions, with a further exploration of the associations between PET semiquantitative data and immunohistochemical markers to liver cancer.
Methods: Patients with suspected malignant liver lesions (MLL) underwent [18F]FDG and [18F]FAPI-04 PET/CT scanning. Liver lesions were visually classified as positive or negative based on their uptake level exceeding that of adjacent normal liver tissue. SUVmax and tumor-to-background ratio (TBR) were recorded for semi-quantitative analysis. Sensitivity, specificity and accuracy of each tracer were determined using pathological findings as the gold standard. Furthermore, immunohistochemical analysis provided the molecular characteristics of all MLLs. Comprehensive analysis explored correlations between these molecular markers and PET semiquantitative parameters (SUVmax andTBR) to identify potential associations.
Results: The study enrolled 44 patients, with 39 confirmed cases of MLL, comprising 28 hepatocellular carcinomas (HCC) and 11 intrahepatic cholangiocarcinomas (ICC). For MLL detection, [18F]FAPI-04 and [18F]FDG exhibited sensitivities of 84.6% (33/39) and 76.9% (30/39), specificitiesy of 60% (3/5) and 100%(5/5), and accuracy of 81.8% (36/44) and 79.5%(35/44). Across all liver lesions, [18F]FAPI-04 significantly surpassed [18F]FDG in SUVmax(10.54 ± 6.72 VS. 7.68 ± 6.79) and TBR(4.35 ± 3.78 Vs. 3.17 ± 3.05). Notably, [18F]FAPI-04 displayed markebly elevated SUVmax in benign liver lesions (BLLs) (P = 0.032), HCCs (P = 0.005), and ICCs (P = 0.011). Lesions with hepatocyte negativity (P = 0.023), CD34 negativity(P = 0.044), and high Ki67 expression (> 30%) (P = 0.001) had higher SUVmax on [18F]FAPI-04. Additionally, ARG-1-negative lesions demonstrated higher TBR on [18F]FAPI-04 than ARG-1-positive lesions(P = 0.018). No significant SUVmax/TBR differences were observed with [18F]FDG based on these markers. A linear relationship was identified between Ki67 scores and SUVmax of [18F]FAPI-04 (R = 0.603, P < 0.001).
Conclusion: [18F]FAPI-04 exhibits superior performance over [18F]FDG in PET/CT evaluation of liver cancer, characterized by increased sensitivity and SUVmax/TBR. Significant correlations with molecular markers, including Ki67, suggest [18F]FAPI-04's potential for characterizing liver cancer subtypes and assessing tumor proliferation. However, further research is required to validate these findings and their clinical significance.

Background: The European Organization of Research and Treatment of Cancer (EORTC) has recently developed and validated a patient-reported outcome measure (PROM) for sexual health (SH) in cancer patients. Here, we present results from a secondary analysis of the EORTC QLQ-SH22 validation study. The objective was to investigate the impact of cancer treatment on SH over the disease trajectory into survivorship in patients who underwent curative treatment.
Methods: Participants completed the EORTC QLQ-SH22 and the EORTC QLQ-C30 assessing SH and Quality of Life. We analyzed differences in SH of patients on active cancer treatment compared to patients off-treatment (cross sectional group comparison) as well as changes in SH during the course of treatment (from pre-treatment to follow-up).
Results: Our sample consisted of n = 394 (66.2% females) curatively treated cancer patients with 34% of patients being on-treatment and 66% of patients being in their follow-up after primary treatment (off-treatment group). Compared to patients off- treatment, patients on active cancer treatment experienced less sexual satisfaction (p = .021, Cohen's d = .36) and libido (p < .001, d = .60) and had higher levels of fatigue (p < .001, d = .50). Importance of sexual activity, masculinity and femininity did not differ between groups. Treatment effects on sexual activity decreased with treatment completion (p < .001, d = .50). Patients undergoing intensified treatment (chemotherapy, radiation, or endocrine treatment) reported more treatment effects (subscale EORTC QLQ-SH22) compared to patients undergoing surgery only.
Conclusion: Our results highlight the negative impact of oncological treatment on SH and how increasing treatment intensity further impair SH. Sexual satisfaction and libido improve after treatment completion while other aspects (e.g. masculinity/femininity) do not change during survivorship. We suggest monitoring of SH from the start of cancer treatment on and beyond into survivorship using PROMs as part of routine cancer care. Routine monitoring allows systematic identification of patient's SH problems and may improve awareness as well as target intervention for those in need of care.
背景:欧洲癌症研究和治疗组织(EORTC)最近针对癌症患者的性健康(SH)问题开发并验证了一种患者报告结果测量法(PROM)。在此,我们介绍 EORTC QLQ-SH22 验证研究的二次分析结果。该研究的目的是调查癌症治疗对接受治愈性治疗的患者在疾病存活期间性健康的影响:方法:参与者完成 EORTC QLQ-SH22 和 EORTC QLQ-C30 评估 SH 和生活质量。我们分析了接受积极癌症治疗的患者与未接受治疗的患者在SH方面的差异(横断面组间比较),以及SH在治疗过程中的变化(从治疗前到随访):我们的样本包括 n = 394 名(66.2% 为女性)接受过根治性治疗的癌症患者,其中 34% 的患者正在接受治疗,66% 的患者正在接受初治后的随访(非治疗组)。与未接受治疗的患者相比,接受积极癌症治疗的患者的性满意度(p = .021,Cohen's d = .36)和性欲(p 结论:与未接受治疗的患者相比,接受积极癌症治疗的患者的性满意度和性欲较低:我们的研究结果凸显了肿瘤治疗对性欲的负面影响,以及治疗强度的增加如何进一步损害性欲。治疗结束后,性满意度和性欲会有所改善,而其他方面(如男性气质/女性气质)在存活期间不会发生变化。我们建议使用 PROMs 作为常规癌症护理的一部分,从癌症治疗开始及之后的生存期对 SH 进行监测。通过常规监测,可以系统地发现患者的 SH 问题,从而提高对 SH 问题的认识,并对需要护理的患者进行有针对性的干预。

Background: Mesenchymal epithelial transition factor (MET) variant is an independent prognostic factor for worse prognosis in patients with lung cancer or gastroesophageal adenocarcinoma. MET gene variants can be regarded as a subtype of melanoma but there is a lack of studies regarding the frequency of MET genetic alterations and the efficacy of immunotherapy in melanoma patients. The purpose of this study is to explore potential therapeutic strategies for melanoma subtypes with MET alterations.
Methods: A total of 1751 malignant melanomas were analyzed to illustrate the landscape of MET mutations. We collected 55 melanoma cases from multicenter for a retrospective cohort from 2010 to 2023. We analyzed the impact of MET amplification on the efficacy of immunotherapy in the retrospective cohort after propensity score matching (PSM) and a pancancer cohort. CIBERSORT was used to evaluate the immune infiltration.
Results: There were no instances of MET 14 exon skipping, and only instances of MET amplification were found in the 1751 melanomas and our retrospective cohort. Cox proportional hazards model analysis showed that MET amplification (P = 0.006) was significantly associated with poorer overall survival (OS) in patients who received immunotherapy as the first-line treatment. Compared with patients with MET amplification, patients in the negative control (NC) group had a significantly better OS (P = 0.022) after PSM. Analysis of 1661 pancancer cases with the MSK-IMPACT assay showed that patients receiving immunotherapy in the MET amplification group had a trend toward worse OS than those without MET amplification (P = 0.025).
Conclusions: This database analysis showed that the main type of MET mutation is amplification in malignant melanoma. MET-amplified solid tumors might be considered for targeted therapy, as MET amplification can be regarded as a risk factor affecting the prognosis of patients with tumors treated with immunotherapy.
背景:间质上皮转化因子(MET)变异是肺癌或胃食管腺癌患者预后较差的独立预后因素。MET 基因变异可被视为黑色素瘤的一种亚型,但目前还缺乏有关黑色素瘤患者 MET 基因变异频率和免疫疗法疗效的研究。本研究的目的是探索针对有MET基因改变的黑色素瘤亚型的潜在治疗策略:分析了1751例恶性黑色素瘤,以说明MET基因突变的情况。我们收集了来自多中心的 55 例黑色素瘤病例,进行了 2010 年至 2023 年的回顾性队列研究。我们分析了倾向得分匹配(PSM)后的回顾性队列和胰腺癌队列中 MET 扩增对免疫疗法疗效的影响。CIBERSORT用于评估免疫浸润:结果:在1751例黑色素瘤和我们的回顾性队列中,没有发现MET 14外显子跳越的情况,只有MET扩增的情况。Cox比例危险模型分析显示,在接受免疫疗法作为一线治疗的患者中,MET扩增(P = 0.006)与较差的总生存期(OS)显著相关。与MET扩增患者相比,阴性对照(NC)组患者在PSM后的OS明显更好(P = 0.022)。利用MSK-IMPACT检测方法对1661例胰腺癌病例进行的分析表明,与无MET扩增的患者相比,接受免疫治疗的MET扩增组患者的OS有变差的趋势(P = 0.025):该数据库分析表明,恶性黑色素瘤的主要MET突变类型是扩增。MET扩增的实体瘤可考虑接受靶向治疗,因为MET扩增可被视为影响接受免疫疗法的肿瘤患者预后的风险因素。
