BACKGROUND: Colitis was the third most common immune-related adverse effect in melanoma patients treated with immune-checkpoint inhibitor (ICI). With the limitation of real-world data in the UK population, this study was conducted in a UK hospital where a fresh colitis guidance was introduced to evaluate the overall grading (OG) to assess colitis severity and guide the treatment. AIMS: This study aimed to investigate colitis severity by Common Terminology Criteria for Adverse Events (CTCAE) grade and overall grade at time of presentation...

BACKGROUND: Immune checkpoint inhibitors (ICIs) have significantly improved outcomes in various cancers. ICI treatment is associated with the incidence of immune-related adverse events (irAEs) which can affect any organ. Data on irAEs occurrence in relation to sex- differentiation and their association with gender-specific factors are limited. AIMS: The primary objective of the G-DEFINER study is to compare the irAEs incidence in female and male patients who undergo ICI treatment...

Hepatocellular carcinoma (HCC) presents a malignant pathology known for its high early recurrence rate following curative treatment, significantly impacting patient prognosis. Currently, effective strategies to mitigate early HCC recurrence remain undetermined. In this report, we document a case of HCC managed with curative radiofrequency ablation (RFA), particularly in a patient facing a high risk of early recurrence due to a substantial tumor size. In an effort to forestall recurrence, immune checkpoint inhibitors (ICIs) were preemptively administered for 6 months post-RFA...

BACKGROUND AND OBJECTIVE: Immune checkpoint inhibitors (ICIs) and antibody-drug conjugates (ADCs) herald a transformative era in metastatic renal cell carcinoma (RCC) and transitional cell carcinoma (TCC) treatment, amid acknowledged sex-based disparities in these cancers. We conducted a systematic review and network meta-analysis (NMA) to identify sex-specific differences in the efficacy of ICI/ADC monotherapy or combination therapies for RCC and TCC survival, in metastatic and adjuvant settings...

Nasopharyngeal carcinoma (NPC) is one of the most common malignant tumors, and stages III and IV are frequently diagnosed. In recent years, immunotherapy has achieved remarkable results in recurrent/metastatic NPC, and many studies related to immunotherapy for NPC have been published. However, to date, no relevant bibliometric studies have been published. The trends and research focus on NPC immunotherapy are analyzed in this study through bibliometric analysis, which is conducive to better understanding the status quo and future trends of immunotherapy for NPC...

Head and neck squamous cell carcinoma (HNSCC) is a highly aggressive, heterogeneous tumour usually caused by alcohol and tobacco consumption, making it one of the most common malignancies worldwide. Despite the fact that various therapeutic approaches such as surgery, radiation therapy (RT), chemotherapy (CT) and targeted therapy have been widely used for HNSCC in recent years, its recurrence rate and mortality rate remain high. RT is the standard treatment choice for HNSCC, which induces reactive oxygen species production and causes oxidative stress, ultimately leading to tumour cell death...

Malignant pleural effusion (MPE) is one of the common complications of lung cancer. The quality of life and prognoses for MPE patients are significantly compromised. Controlling the production of MPE can relieve patients' symptoms, improve their quality of life, and prolong their survival. This article presents a case of advanced non-small cell lung cancer (NSCLC) with MPE and negative driver genes. The patient received envafolimab and Endostar in combination, resulting in a complete reduction of MPE and durable clinical benefits...

BACKGROUND: The cancers of the digestive tract, including colorectal cancer (CRC), gastric cancer (GC) and Esophageal cancer (ESCA), are part of the most common cancers as well as one of the most important leading causes of cancer death worldwide. SUMMARY: Despite the emergence of immune checkpoint inhibitors (e.g., anti-CTLA-4 and anti-PD-1/PD-L1) in the past decade, offering renewed optimism in cancer treatment, only a fraction of patients derive benefit from these therapies...

OBJECTIVES: To report an autoimmune paraneoplastic encephalitis characterized by immunoglobulin G (IgG) antibody targeting synaptic protein calmodulin kinase-like vesicle-associated (CAMKV). METHODS: Serum and cerebrospinal fluid (CSF) samples harboring unclassified antibodies on murine brain-based indirect immunofluorescence assay (IFA) were screened by human protein microarray. In 5 patients with identical cerebral IFA staining, CAMKV was identified as top-ranking candidate antigen...

INTRODUCTION: Treatment for recurrent ovarian clear cell carcinoma (OCCC) is clinically challenging as response rates to traditional chemotherapy are low, and recurrence rates are high. Immunotherapy has shown promise for this ovarian cancer (OC) subtype, and tumor molecular testing allows for the identification of a patient population that might benefit most from this treatment. We describe the clinical course and somatic genomic testing of 4 patients who received pembrolizumab for recurrent OCCC concurrent with a combination of bevacizumab and/or cyclophosphamide...

BACKGROUND: novel oncologic therapies, including epidermal growth factor receptor inhibitors (EGFR-Is) and immune checkpoint inhibitors (ICIs), are associated with a new spectrum of adverse reactions, with prominent cutaneous toxicities. The impact of cutaneous adverse events (cAEs) on patients' quality of life (QoL) represents an unmet clinical need. OBJECTIVES: 1) to assess whether cutaneous toxicities directed therapies are effective in reducing the QoL burden via the submission of two patient reported outcome measures (PROMs); 2) to investigate whether class of oncologic therapy, type of cAE and toxicity severity differently impact on patients' QoL...

Tumor microenvironment is an intricate web of stromal and immune cells creating an immune suppressive cordon around the tumor. In hepatocellular carcinoma (HCC), Tumor microenvironment is a formidable barrier towards novel immune therapeutic approaches recently evading the oncology field. In this study, the main aim was to identify the intricate immune evasion tactics mediated by HCC cells and to study the epigenetic modulation of the immune checkpoints; Programmed death-1 (PD-1)/ Programmed death-Ligand 1 (PD-L1) and T cell immunoreceptor with Ig and ITIM domains (TIGIT)/Cluster of Differentiation 155 (CD155) at the tumor-immune synapse...

BACKGROUND: Immune checkpoint inhibitors (ICI) have improved outcomes in a variety of adult cancers and are prescribed with increasing frequency across oncology. However, patterns of off-label use of ICI in pediatrics remain unclear. METHODS: This is a single-institution, retrospective cohort study evaluating off-label ICI use in pediatric and young adult patients with cancer treated at our institution from 2014 to 2022. Response was based on clinician assessment derived from clinical records...

Immunotherapy has renovated the field of oncology. Usually, cancer is treated by surgery, chemotherapy, and radiation. Immunotherapy is a promising treatment that harnesses the patient's own immune system to target cancer. Immune checkpoint inhibitors (ICIs) have proven to be a promising treatment avenue for managing cancer; however, their use had been associated with a unique spectrum of adverse side effects called immune-related adverse events (irAEs). As ICIs become increasingly relevant in cancer management, it is crucial to address these irAEs affecting various systems in the body, including the skin, liver, gastrointestinal tract, endocrine system, and the eye...

BACKGROUND: The efficacy of anti-PD-1 therapy is primarily hindered by the limited T-cell immune response rate and immune evasion capacity of tumor cells. Autophagy-related protein 7 (ATG7) plays an important role in autophagy and it has been linked to cancer. However, the role of ATG7 in the effect of immune checkpoint blockade (ICB) treatment on high microsatellite instability (MSI-H)/mismatch repair deficiency (dMMR) CRC is still poorly understood. METHODS: In this study, patients from the cancer genome altas (TCGA) COAD/READ cohorts were used to investigate the biological mechanism driving ATG7 development...

BACKGROUND: Mesenchymal epithelial transition factor (MET) is a rare oncologic driver gene, and information on immunotherapy for non-small cell lung cancer (NSCLC) patients with this driver gene is limited. Here we evaluate the efficacy and safety of immune checkpoint inhibitors (ICI) under different therapeutic regimen for NSCLC patients with MET alterations. METHODS: From June 2019 to December 2023, we assessed the efficacy and toxicity of ICIs in 42 NSCLC patients with MET alterations...

IMPORTANCE: Randomized clinical trials (RCTs) with neoadjuvant immune checkpoint inhibitors (ICIs) plus chemotherapy (ICI-chemotherapy) for patients with early-stage non-small cell lung cancer (NSCLC) have reported consistent associations with event-free survival (EFS) and pathologic complete response (pCR) pending longer follow-up for overall survival data. OBJECTIVE: To assess the pooled benefit of ICI-chemotherapy in 2-year EFS and pCR among patients with NSCLC and examine the impact of clinical, pathologic, and treatment-related factors...

BACKGROUND: The use of immune checkpoint inhibitors has led to an increase in randomized controlled trials exploring various first-line combination treatment regimens. With the introduction of new PD-1/PD-L1 inhibitors, there are now more clinical options available. For the first time, the AK105 monoclonal antibody Penpulimab, developed in China, was included. The AK105-302 Phase III trial studied the efficacy and safety of Penpulimab combined with chemotherapy in patients with advanced or metastatic squamous NSCLC...
