    Abstract Choriocarcinoma (CC) is a malignant neoplasm of the trophoblastic tissue, with a potential to metastasise to distant organs. Limited case of gestational CC develops after a long latent period. We report a 52-year-old postmenopausal woman who developed metastatic choriocarcinoma presumably of gestational origin, 8 years after the last pregnancy and 2 years after the last menstrual period. The patient was brought to the emergency room of a tertiary care centre in Muscat, Oman, in 2022 and was diagnosed with CC metastatic to the brain, spleen, lung and the kidney. The β-human chorionic gonadotrophin level was found to be raised (1,292,867 mIU/mL). The International Federation of Gynecologic Oncology risk score was calculated to be 14 (very high risk). The patient was initially treated with whole-brain radiotherapy and splenic artery embolisation because of a hemoperitoneum. Afterwards the patient received systemic treatment using the standard EMA/CO regimen till complete serological remission.

    Abstract Endometrial cancer (EC) is the most common gynaecological cancer. The combination of lenvatinib and pembrolizumab has exhibited efficacy as the second line treatment for advanced EC, with a significant benefit in terms of progression free survival (PFS) and overall survival, but the adverse events (AE) profile is complex. AEs associated with the treatment may represent a limitation to this combination. Here, we report the case of a 38-year-old female patient diagnosed with stage IV EC elsewhere, whose disease progressed after the first line of treatment and was referred to a specialised cacncer centre in Muscat, Oman, in 2021. We treated her with the combination of lenvatinib and pembrolizumab. During the course of the treatment, she developed hand-foot syndrome grade III and hypothyroidism grade II. The AEs were managed with supportive medications, dose interruptions, dose reductions and multidisciplinary care, which allowed the continuation of the treatment. The patient achieved a good partial response and an ongoing PFS of more than 12 months.

    Abstract Crescentic glomerulonephritis has been associated with several solid tumour malignancies. Only a few cases of nephropathy have been reported in association with tubo-ovarian/peritoneal malignancies. We report a 55-year-old female patient who presented to a tertiary care centre, Muscat, Oman, in 2022. She developed combined immune complex-mediated glomerulonephritis and pauci-immune necrotising crescentic vasculitis simultaneously with the diagnosis of tubo-ovarian/peritoneal cancer. The baseline estimated glomerular filtration rate (eGFR) was 13 mL/min. The patient received two doses of rituximab and three doses of pulse corticosteroids, leading to significant improvement in renal function and the disappearance of her proteinuria. The eGFR improved to >60mL/min; her proteinuria gradually resolved after 10 weeks of treatment. She was then given a combination chemotherapy treatment for tubo-ovarian/peritoneal cancer leading to a normalisation of her CA-125 after three months of therapy.

    Abstract A systematic review of the published literature was conducted to analyze the management evolution of brain metastases from different cancers. Using the keywords "brain metastasis", "brain metastases", "CNS metastasis", "CNS metastases", "phase III" AND/OR "Randomized Controlled Trial" (RCT), relevant articles were searched for on the SCOPUS database. A total of 1986 articles were retrieved, published over a 45-year period (1977-2022). Relevant articles were defined as clinical studies describing the treatment or prevention of brain metastases from any cancer. Articles on imaging, quality of life, cognitive impairment after treatment, or primary brain tumors were excluded. After a secondary analysis, reviewing the abstracts and/or full texts, 724 articles were found to be relevant. Publications significantly increased in the last 10 years. A total of 252 articles (34.8%) were published in 12 core journals, receiving 50% of the citations. The number of publications in Frontiers in Oncology, BMC Cancer, and Radiotherapy and Oncology have increased considerably over the last few years. There were 111 randomized controlled trials, 128 review articles, and 63 meta-analyses. Most randomized trials reported on brain metastases management from unselected tumors (49), lung cancer (47), or breast cancer (11). In the last 5 years (2017 to 2022), management of brain metastasis has moved on from WBRT, the use of chemotherapy, and radio-sensitization to three directions. First, Radiosurgery or Radiotherapy (SRS/SRT), or hippocampal-sparing WBRT is employed to reduce radiation toxicity. Second, it has moved to the use of novel agents, such as tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI) and third, to the use of molecularly directed therapy such as TKIs, in asymptomatic low volume metastasis, obviating the need for WBRT.

    Abstract Tubulocystic carcinoma of the kidney (TC-RCC) is a rare renal tumor and has been recently included as a distinct entity in WHO classification of renal neoplasms. We report the case of a patient with metastatic tubulocystic RCC whose disease progressed through standard of care treatment for nonclear RCC. However, genetic analysis revealed a germline pathogenic variant of fumarate hydratase (FH) gene, and the patient had a sustained and durable response to pazopanib.

    Abstract Objectives: Prostate cancer (PCa) is the third most common cancer worldwide, with its incidence rising in the Middle East. There is a paucity of data about the clinicopathological features and outcomes of metastatic prostate cancer (mPCa) from the Middle East. We report the outcomes of mPCa from Oman.
    Methods: We recruited consecutive men diagnosed with mPCa and treated at Sultan Qaboos University Hospital in Oman between January 2006 and December 2017. Information about demographics, clinical, laboratory, pathological, and radiological features at presentation, treatment, and survival outcomes was collected. Data were gathered until April 2019 or until the patient's death for progression-free survival (PFS) and overall survival (OS), whichever came first. Survival rates were estimated using the Kaplan-Meier method. Univariate and multivariate analysis and Cox regression analyses were performed to study factors affecting the PFS and the OS.
    Results: Of the 239 men diagnosed with PCa over the study period, 62 were diagnosed with mPCa. The median age was 71 (range = 57-92) years. The majority of patients (61.3%) had a Gleason score ≥ 8. Median prostate-specific antigen (PSA) level was 100.0. Bone was the most common site of metastatic disease (90.3%). The majority of patients with the hormone-sensitive disease were treated with testosterone suppression only, while abiraterone, enzalutamide, and docetaxel were added for treating metastatic castration-resistant mPCa (mCRPC). After a median follow-up of 34.5 months, the median PFS was 17 months, while the median OS was 43 months. Median survival post mCRPC was 17 months.
    Conclusions: Omani patients with mPCa present with high PSA and Gleason score and with widespread metastatic disease burden. Treatments offered are according to internationally accepted standards and have comparable PFS and OS as reported elsewhere.

    Abstract Introduction Immune checkpoint inhibitors (ICIs) have revolutionized the management of multiple cancers over the last decade. They work by employing the immune system and exhibiting activity over T cells resulting in immune upregulation. Despite their widespread use, they produce side effects that can limit their use. The immune-related adverse events (irAEs) can be sometimes significant. The irAEs caused by ICIs may occur at any time during the treatment and can vary in grade (G). We sought to study the prevalence and toxicity patterns of ICIs in Oman. Methods One hundred forty-one adult patients (≥18 years) who received at least one dose of nivolumab, pembrolizumab, atezolizumab, or durvalumab between 2016 and 2022 were included. The data were analyzed retrospectively using univariable and multiple-variable logistic regressions. The Wilcoxon rank-sum test and Cochran-Armitage trend test were also used to summarize the continuous and ordinal data. Results Out of the 141 patients, 80 patients (56.7%) received pembrolizumab, and 48 (34%) received nivolumab. Common irAEs included endocrine abnormalities, pneumonitis, and colitis. Thirty patients (21.3%) experienced varying irAE grade toxicity. Out of the 30, 23 patients (82%) developed grade 2 and 3 irAEs. Discussion Predictive analysis showed that male sex and lower hemoglobin (Hb) and bilirubin levels were all significant predictors (p < 0.05) when associated with irAE occurrence. The prevalence of irAEs was similar compared to other reports, literature reviews, or meta-analyses. Female sex has been mentioned previously also to be a predictive factor for endocrine-related toxicities.

    Abstract Objectives: This study aimed to explore the relationships between nurses' work environment, job stress and job satisfaction, along with the moderating effects of work environment and empowerment on the relationship between job stress and job satisfaction.
    Methods: A descriptive correlational design was utilised for this study. The study encompassed a convenience sample of 1,796 hospital nurses from the 11 governorates in Oman. Moreover, a self-report questionnaire that included a set of instruments was used to collect the data.
    Results: Nurses who perceived higher levels of job stress reported lower levels of satisfaction and empowerment and perceived their work environment as less favourable and supportive. The findings only confirmed the direct effects of work environment and empowerment on satisfaction, whereas no support was found for indirect or moderating effects. Furthermore, the hierarchical regression model showed that 46.5% of the variation in the level of job satisfaction was explained by the study variables.
    Conclusion: The results of this study demonstrate the importance of implementing strategies that empower staff, provide a supportive and positive work environment and tackle job stress to enhance levels of job satisfaction.
