AI Article Synopsis
- The study aimed to investigate the occurrence and management of endocrine disorders resulting from immune checkpoint inhibitors (ICIs) in cancer patients, specifically focusing on PD-1/PD-L1 inhibitors at a cancer center in Oman.
- Out of 139 patients analyzed, 28% experienced thyroid-related issues, with hypothyroidism being the most common, followed by a few cases of hyperthyroidism and other rarer endocrine complications.
- The findings highlight that factors like weight and body mass index (BMI) play a significant role in the likelihood of developing these endocrine immune-related adverse events, emphasizing the need for healthcare providers to monitor patients closely for potential endocrine dysfunctions post-treatment.
Article Abstract
Objectives: To determine the incidence, presentation, frequency and management of immune checkpoint inhibitors (ICI)-related endocrinopathies in a comprehensive cancer centre in Oman, particularly with programme death 1/programme death-ligand 1 (PD-1/PD-L1) inhibitors.
Background: A high number of patients treated with PD-1/PD-L1 inhibitors for the management of solid tumours developed endocrinopathies.
Methods: This is a retrospective study of patients admitted to Sultan Qaboos Comprehensive Cancer Care and Research Centre (SQCCCRC) from August 2021 to December 2022. All adults diagnosed with solid cancers and have received at least one dose of ICIs were included. Patients with incomplete data were excluded from the analysis. Data regarding the ICI-induced endocrinopathy were collected.
Results: A total of 139 patients were included in the study of which 58% were females. The median age of the cohort was 56 years. The incidence of endocrine-related adverse events was 28%. The mean time for the development of endocrine adverse events after treatment initiation was 4.1 ± 2.8 months. Of the patients who developed toxicity, 90% had hypothyroidism. Ten patients developed hyperthyroidism, two patients were diagnosed with secondary adrenal insufficiency/hypophysitis and one patient developed Type 1 diabetes mellitus (DM). Using univariable logistic regression weight and body mass index (BMI) significantly impacted the development of endocrine immune-related adverse events (irAEs).
Conclusions: This is the first study from the Sultanate of Oman to assess PD-1/PDL-1 ICI-induced endocrinopathies. The most common endocrine adverse event is thyroid dysfunction, mainly hypothyroidism followed by hyperthyroidism. Hypophysitis, primary adrenal insufficiency and CIADM occur less frequently, but have a more significant effect on the patient's health. The treating physician should be aware of ICI-induced endocrinopathies, screening and treatment. Furthermore, our study showed that patients with a higher BMI have a greater risk of developing irAES. Further studies are needed to establish the predictors of endocrine irAEs.

Smurfit Institute of Genetics, Trinity College Dublin, Dublin 2, Ireland. Electronic address:
Polycomb repressive complex 2 (PRC2), composed of the core subunits EED, SUZ12, and either EZH1 or EZH2, is critical for maintaining cellular identity in multicellular organisms. PRC2 deposits H3K27me3, which is thought to recruit the canonical form of PRC1 (cPRC1) to promote gene repression. Here, we show that EZH1-PRC2 and cPRC1 are the primary Polycomb complexes on target genes in non-dividing, quiescent cells.

Sex differences in melanoma are prominent, with females having a significant survival advantage. However, it is unclear why we see this survival advantage. Here we investigate the relationship between sex, clinicopathologic variables, and melanoma specific survival in 1,753 single primary melanomas from patients in the GEM study.

Childhood cancers are a heterogeneous group of rare diseases, accounting for less than 2% of all cancers diagnosed worldwide. Most countries, therefore, do not have enough cases to provide robust information on epidemiology, treatment, and late effects, especially for rarer types of cancer. Thus, only through a concerted effort to share data internationally will we be able to answer research questions that could not otherwise be answered.

Article Synopsis
- Hepatitis B virus (HBV) is a major global health concern linked to liver disease and cancer, with research focusing on genetic factors that affect its evolution.
- Recent studies highlighted the ECM1 gene, specifically two polymorphisms (rs3834087 and rs3754217), which may influence HBV pathogenesis, particularly in an African cohort analyzed in this research.
- The study found that the heterozygous genotype of rs3754217 appears to protect against chronic hepatitis, suggesting that certain genetic variations may impact the severity of the disease in infected individuals.

Article Synopsis
- Lung cancer has the highest incidence and mortality rates globally, making effective post-surgical mental health support crucial due to associated challenges like anxiety and depression.
- Traditional Chinese medicine shows promise in improving psychological well-being and physical symptoms after lung cancer surgery, but its effectiveness specifically for mental function recovery needs investigation.
- The study will systematically review various databases for randomized controlled trials focusing on depression and anxiety after lung cancer surgery, assessing data quality and outcomes using established evaluation tools.
