Aim: Studies on immune checkpoint inhibitor (ICI)-related potential neurological adverse events (pNAEs) in Korean lung cancer (LC) patients are scarce. We aimed to examine ICI prescription trends from 2018 to 2022, patient characteristics and factors associated with ICI prescription or concurrent pNAEs in LC.Research design & methods: This observational, cross-sectional study of Korean LC patients investigated four ICIs (pembrolizumab, nivolumab, atezolizumab and durvalumab). The annual ICI prescription rate was calculated by dividing the number of LC patients prescribed ICIs with the total annual number of LC patients. Factors associated with ICI prescriptions or concurrent pNAEs were assessed.Results: The annual ICI prescription rate increased from 3.29% to 9.74% (average: 6.20%). Higher Charlson Comorbidity Index (CCI) scores were associated with more ICI prescriptions (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.07-1.08). Targeted therapy was associated with fewer prescriptions (OR: 0.45; 95% CI: 0.41-0.49). The anti-programmed cell death protein 1 (anti-PD-1) prescription rate was higher in patients with concurrent pNAEs than those without pNAEs (53.09% vs. 50.84%), and this was associated with higher pNAEs prevalence (OR: 1.10; 95% CI: 1.03-1.18).Conclusion: ICI prescription for LC has increased in Korea, CCI and anti-PD-1 increased pNAEs prevalence.

Aim: To understand physicians' attitudes and behaviors regarding EGFR testing and retesting strategies in newly diagnosed metastatic non-small cell lung cancer patients.Materials & methods: Oncologists and pathologists completed an online, cross-sectional survey.Results: Most oncologists (73.3%) and pathologists (53.4%) agreed that concurrent testing increases sensitivity for detecting EGFR mutations. Upon tissue insufficiency, oncologists and pathologists reported using liquid biopsy 77.0% and 39.0% of the time, respectively. Tumor accessibility, smoking status, patient willingness and age were key drivers of tissue re-biopsy. Most oncologists reported high confidence in proceeding to first-line therapy based solely on liquid biopsy (60.7-80.0%); fewer pathologists (37.9%) were comfortable with this decision.Conclusion: Variation in physicians' perceptions of testing and retesting highlights the need for greater stakeholder consensus.

What is this summary about?: This article presents a patient-friendly summary of the MOTION phase 3 clinical trial results, which were published in The Lancet in June 2024.The primary goal of the MOTION trial was to understand if treatment with a drug called vimseltinib shrank tumors more than a placebo in participants with symptomatic tenosynovial giant cell tumor, also known as TGCT, for which surgery was unlikely to provide benefit. A placebo is something that looks like the treatment being studied but does not contain any medicine.The MOTION trial compared the effects of vimseltinib versus a placebo using several different outcomes associated with TGCT. These outcomes included tumor size, active range of motion of the affected joint, and several patient-reported quality-of-life measures including physical function, stiffness, overall health, and pain.

What were the main conclusions reported by the researchers?: The trial showed that more participants treated with vimseltinib experienced significant tumor shrinkage, as defined by a 30% or greater reduction in tumor size, compared with those receiving a placebo. Participants receiving vimseltinib had improved active range of motion, and they reported improved physical function, stiffness, overall health, and pain, regardless of the amount of tumor shrinkage, compared with participants receiving a placebo. Most side effects in participants treated with vimseltinib were not severe and were manageable.

What are the key takeaways?: Vimseltinib was better at shrinking tumors and improving active range of motion, stiffness, pain, and other health measures than the placebo for participants with TGCT. Vimseltinib has the potential to become a new treatment option for patients with TGCT for whom surgery may not provide benefit.

Drug resistance remains a major obstacle in cancer treatment, leading to treatment failures and high mortality rates. Despite advancements in therapies, overcoming resistance requires a deeper understanding of its mechanisms. This review highlights CDK2's pivotal role in both intrinsic and acquired resistance, and its potential as a therapeutic target. Cyclin E upregulation, which partners with CDK2, is linked to poor prognosis and resistance across various cancers. Specifically, amplifications of CCNE1/CCNE2 are associated with resistance to targeted therapies, immunotherapy, endocrine therapies and chemo/radiotherapy. Given CDK2's involvement in resistance mechanisms, investigating its role presents promising opportunities for developing novel strategies to combat resistance and improve treatment outcomes.

Objectives: To evaluate the effects of CALM intervention on cancer-related fatigue (CRF), quality of life (QOL), and heart rate variability (HRV) in non-small cell lung cancer (NSCLC) patients.

Methods: A total of 153 NSCLC patients were enrolled in the study. Participants were randomly assigned to the CALM group and usual care (UC) group. Patients in the CALM group were received 6 CALM intervention sessions over a 12-week period and evaluated using CRF, QOL and HRV at baseline (T0) and after 2, 4, and 6 intervention sessions.

Results: The CALM group showed significant differences in total CRF, behavioral/daily life CRF, emotional/affective CRF, sensory/physical CRF, cognitive CRF and QOL before and after CALM intervention sessions (F = 643.47, F = 208.34, F = 354.52, F = 285.69, F = 334.29, F = 245.77, p < 0.001). The CALM group showed significant increases in standard deviation of normal R-R interval (SDNN) and high-frequency power (HF) (z = -4.94, p < 0.001,z = -4.30, p < 0.001). Significant negative correlations were observed between CRF and SDNN, HF and QOL across all participants.

Conclusions: The CALM intervention had a positive impact on overall physical and mental health, fatigue reduction, quality of life and autonomic dysfunction in NSCLC patients. Heart rate variability may serve as an observational indicator of physical and mental health.

Aim: To investigate the prognostic value of inflammatory markers in esophageal squamous cell carcinoma (ESCC) patients treated with immune checkpoint inhibitors (ICIs).Materials & methods: The infiltration of CD3⁺ and CD8⁺ T cells in tissue microarrays from 180 patients who underwent radical esophagectomy was detected using immunohistochemistry. A separate cohort of 351 patients with metastatic/recurrent or unresectable ESCC treated with ICIs was enrolled for further investigation. The overall survival difference among groups was assessed using Kaplan-Meier analysis. Cox proportional hazards models were employed to investigate the prognostic impact of the inflammatory markers, along with other factors.Results: Decreased inflammation was found to be associated with increased CD3⁺ and CD8⁺ T-cell infiltration and a better prognosis. Then, the value of inflammatory markers in predicting survival in 351 ESCC patients receiving immunotherapy was validated. Ultimately, the systemic immune-inflammation index was identified as an independent prognostic factor for overall survival. Additionally, the patients with no distant organ metastasis, or treated by first-line immunotherapy combined with concurrent chemoradiotherapy can considerably prolong survival.Conclusion: Inflammation is associated with the level of tumor infiltrating lymphocytes and that the systemic immune-inflammation index is an effective prognostic predictor for ESCC patients treated with ICIs.

Medulloblastoma (MB) is the most frequent malignant brain tumor in children. MB originates from neural precursor cells in distinctive regions of the rhombic lip and their maturation occurs in the cerebellum or the brain stem during embryonal development. Autophagy is also referred to as self-eating' which is a catabolic process that often triggers cellular homeostasis through the salvaging of degenerated proteins as well as organelles. Autophagy influence cell survival via aberrant proteins that could accumulate within the cell and influence potential signaling and transport mechanisms. The role of autophagy in MB aggressiveness as well as tumorigenesis is a very complex process. This review targets specifically data reporting the key roles of autophagy in the pathogenesis and therapy of MB.

Introduction: Physical activity is associated with improved functionality, independence and quality of life in cancer patients undergoing active treatment. Exercises can be prescribed to improve patient outcomes.

Objective: Evaluate the effects of applied exercise protocols on functional capacity, quality of life, fatigue and muscle strength in hospitalized onco-hematological patients compared to conventional treatment.

Method: Systematic literature review carried out in PUBMED, EMBASE and Scopus databases with the following descriptors: Hematological neoplasms AND Exercise Therapy AND Hospitalization, in November 2023. Studies with adult inpatients with hematological neoplasms who performed an exercise protocol in the intervention group were included.

Results: After applying the eligibility criteria, 9 articles were included in the review, 7 of which were randomized clinical trials and 6 were carried out on transplant patients. The most commonly assessed outcome was functional capacity, followed by muscle strength and quality of life, and ending with an assessment of fatigue. Studies have shown positive results for patients, especially those that combine resistance and aerobic exercise protocols.

Conclusion: An exercise protocol for patients with onco-hematological diseases can improve the outcomes analyzed. Aerobic and resistance exercises should be performed, but more studies are needed to assess the time and doses required for each activity.

Objective: To investigate the application value of multimodality ultrasound in the evaluation of lymphoma.

Methods: The regression models were performed to determine whether there were differences in differentiating lymphoma from benign lymph nodes. Receiver operator curves were drawn to evaluate the diagnostic performance of three ultrasound modalities.

Results: Multivariate analysis showed statistically significant differences in the long to short axes ratio, visibility of the hilum, Adler grade of blood flow, cortical echo, maximum elasticity, elastic color pattern, enhancement distribution, and Area. The combination of three modalities achieved a sensitivity of 95.6%, specificity of 87.5%, accuracy of 93.5%, positive predicted value of 97.0%, and negative predicted value of 82.4%.

Conclusion: Multimodal ultrasound can provide valuable differential diagnosis and improve the diagnostic performance.
