Breast cancer stands as the prevailing malignancy across all six Gulf Cooperation Council (GCC) nations. In this literature review, we highlighted the incidence and trend of breast cancer in the GCC. Most of the studies reported a consistent increase in breast cancer incidence over the past decades, which was particularly attributed to the adoption of a Westernized lifestyle in the region and the implications of emerging risk factors and other environmental and societal factors, the increase in screening uptake, as well as the improvement in data collection and reporting in the GCC. The data on breast cancer risk factors in the GCC were limited. In this geographic region, breast cancer frequently manifests with distinctive characteristics, including an early onset, typically occurring before the age of 50; an advanced stage at presentation; and a higher pathological grade. Additionally, it often exhibits more aggressive features such as human epidermal growth factor receptor 2 (HER2) positivity or the presence of triple-negative (TN) attributes, particularly among younger patients. Despite the growing body of literature on breast cancer in the GCC, data pertaining to survival rates are, regrettably, meager. Reports on breast cancer survival rates emanating from the GCC region are largely confined to Saudi Arabia and the United Arab Emirates (UAE). In the UAE, predictive modeling reveals 2-year and 5-year survival rates of 97% and 89%, respectively, for the same period under scrutiny. These rates, when compared to Western counterparts such as Australia (89.5%) and Canada (88.2%), fall within the expected range. Conversely, Saudi Arabia reports a notably lower 5-year survival rate, standing at 72%. This disparity in survival rates underscores the need for further research directed toward elucidating risk factors and barriers that hinder early detection and screening. Additionally, there is a pressing need for expanded data reporting on survival outcomes within the GCC. In sum, a more comprehensive and nuanced understanding of breast cancer dynamics in this region is imperative to inform effective strategies for prevention, early detection, and improved patient outcomes.

The increasing cancer burden is a major health concern in Arab countries with cross-regional variations in cancer profiles. Given the limited oncology research output and scarce data on cancer trial participation in the Arab region, this study explored the therapeutic cancer trial landscape in Arab countries over the past 20 years. A bibliometric analysis of the PubMed database was conducted on primary publications of therapeutic trials with a participating Arab center. Arab countries participated in 320 published cancer-related therapeutic trials (2000–2021). During this period, there was a consistent increase in the number of trials, sample size, multiregional site participation, and number of randomized trials. However, most trials were small, did not receive external funding, and included a single Arab site. Compared with Arab-only trials, trials with joint non-Arab sites were larger (p = 0.003) and more likely to be externally funded (p < 0.001). Citation numbers and journal impact factors were higher in trial publications with joint non-Arab authorship than those without (p < 0.001, for both). Despite improving conduct and publication records of oncology trials with Arab centers, cancer trial participation remains limited in Arab countries. Concerted efforts are required to encourage sponsorship and international collaboration in this region. Full article

The United Arab Emirates (UAE) has one of the fastest growing economies in the world, which has resulted in an increase in the detection of noncommunicable diseases such as cancer. Despite its screening and early detection efforts falling short of the target coverage of the intended population, the number of reported cases and deaths in UAE has increased over the years. A few studies have been conducted to understand the hurdles to cancer screening in UAE, mostly focusing on breast and colorectal malignancies. There are no studies or surveys that have addressed the barriers and hurdles to overall cancer screening in UAE’s population. Through this is the largest survey to date, we aimed at assessing UAE society’s perception of cancer and early screening and detection. The survey was constructed using the SurveyPlanet platform. The survey was then distributed on social media for direct and snowball sampling, including Instagram, WhatsApp, LinkedIn, Meta (Facebook), and Twitter. Interestingly, 71.3% of the respondents reported that they were fine mentioning or discussing cancer, while 28.2% reported that they were not comfortable with it. Moreover, 91.8% of the respondents knew the meaning of the early detection or screening of cancer, while 8.2% did not. The ability of respondents to correctly identify different types of cancer screening varied. This study suggests that regulatory authorities need to raise more awareness about cancer, especially among younger generations, and create screening recommendations and guidelines that should include younger people. Lastly, hospitals, cancer charity organizations, educational institutes, and the media should address target audiences to raise cancer awareness among them. Full article

The rationale for administering immune checkpoint inhibitors (ICIs) in the adjuvant setting is to eradicate micro-metastases and, ultimately, prolong survival. Thus far, clinical trials have demonstrated that 1-year adjuvant courses of ICIs reduce the risk of recurrence in melanoma, urothelial cancer, renal cell carcinoma, non-small cell lung cancer, and esophageal and gastroesophageal junction cancers. Overall survival benefit has been shown in melanoma while survival data are still not mature in other malignancies. Emerging data also show the feasibility of utilizing ICIs in the peri-transplant setting for hepatobiliary malignancies. While ICIs are generally well-tolerated, the development of chronic immune-related adverse events, typically endocrinopathies or neurotoxicities, as well as delayed immune-related adverse events, warrants further scrutiny regarding the optimal duration of adjuvant therapy and requires a thorough risk–benefit determination. The advent of blood-based, dynamic biomarkers such as circulating tumor DNA (ctDNA) can help detect minimal residual disease and identify the subset of patients who would likely benefit from adjuvant treatment. In addition, the characterization of tumor-infiltrating lymphocytes, neutrophil-to-lymphocyte ratio, and ctDNA-adjusted blood tumor mutation burden (bTMB) has also shown promise in predicting response to immunotherapy. Until additional, prospective studies delineate the magnitude of overall survival benefit and validate the use of predictive biomarkers, a tailored, patient-centered approach to adjuvant ICIs that includes extensive patient counseling on potentially irreversible adverse effects should be routinely incorporated into clinical practice.

Cancer is the third-leading cause of death in the United Arab Emirates (UAE); cancer care in the UAE has evolved dramatically over the last 40 years, from a single center in Al Ain in 1981 to more than 30 cancer centers and clinics across the UAE, with at least four comprehensive cancer centers in the UAE nowadays. Despite the significant progress in medical care, cancer quality control across the UAE is still lacking, with significant variations in cancer care across the cancer centers. Access to clinical trials is still hampered by a lack of expertise and research infrastructure and a small population, which renders patient accrual for trials a major challenge. Education and training are other areas for improvement that require immediate attention, and, in this review, we try to address these critical aspects for stakeholders to consider better cancer care in the UAE. Early cancer detection and screening are still evolving in the UAE, and a national screening program is lacking. There is also a need to address barriers to screening and to consider less invasive screening methods such as approved blood-based screening, which is likely to be more acceptable to the UAE population. In this review, we also address new topics that have not been addressed previously, including oncology medical tourism, psycho-oncology, onco-fertility, precision oncology, survivorship, oncology nursing, cancer support programs, and the oncology sector’s response to the COVID-19 pandemic, all in the context of the UAE cancer landscape. Finally, we provide recommendations for policymakers, regulators, payers, patient advocacy groups, and the UAE oncology community regarding the delivery and future planning of high-quality cancer care. These recommendations are aligned with the UAE government’s vision to reduce cancer mortality and provide high-quality healthcare for its citizens and residents. Full article

Cancer research and clinical trials are essential to improve cancer patients’ outcomes and advance the oncology field. The United Arab Emirates (UAE) has been lagging in cancer research with many barriers, including healthcare, institutional, regulatory, patient and community, the global oncology community, and the pharmaceutical industry. In this report, we try to address these challenges from our perspective. Making clinical trials accessible for cancer patients in the UAE requires a collaborative approach from all stakeholders and serious consideration for the greater cause to improve the patient’s outcome and contribute to the advancement of the cancer field worldwide. There has been significant support from the UAE government and the regulators in the UAE to facilitate and encourage research in general and cancer research in particular with recent initiatives and international collaborations. Private and public institutions must overcome their competitive moods and work together to strengthen the research network across the UAE and improve accrual for potential clinical trials. Public awareness and education must overcome long-standing perceptions about research and clinical trials in the UAE. The pharmaceutical industry must work closely with institutions across the UAE and support them in establishing accredited research programs and clinical trial units. The Emirates Oncology Society is establishing the Oncology Research Working Group to advocate and advance cancer research in the UAE. All stakeholders must be engaged to successfully implement impactful clinical trials in the UAE and the region. Full article

The United Arab Emirates (UAE) is one of the fastest growing economies with consequent increase in non-communicable diseases including cancer. The number of reported cases and mortality have been increasing in the UAE over the years, despite screening and early detection efforts which appear to be far from target coverage of the intended population. In this work, we highlight key elements of a proposed national cancer control plan for the UAE. The plan is still a work in progress and has not yet been officially adopted. A comprehensive and effective control plan requires accurate data, a reliable cancer registry, and periodic monitoring and evaluation. The UAE cancer control plan is being prepared in line with the WHO and EMRO framework, with defined objectives and goals. The objectives are to combat cancer, reduce incidence, control mortality, and improve outcomes and quality of life for cancer patients. There is also a focus on improving public health education, prevention, early detection, prompt diagnosis, treatment facilitation, continuity of care, performance evaluation, training of workforce, and research.

Cancer is considered by not only multiple genetic but also epigenetic amendments that drive malignant cell propagation and consult chemo-resistance. The ability to correct or ablate such mutations holds enormous promise for battling cancer. Recently, because of its great efficiency and feasibility, the CRISPR-Cas9 advanced genome editing technique has been extensively considered for therapeutic investigations of cancers. Several studies have used the CRISPR-Cas9 technique for editing cancer cell genomic DNA in cells and animal cancer models and have shown therapeutic potential in intensifying anti-cancer protocols. Moreover, CRISPR-Cas9 may be used to correct oncogenic mutations, discover anticancer drugs, and engineer immune cells and oncolytic viruses for immunotherapeutic treatment of cancer. We herein discuss the challenges and opportunities for translating therapeutic methods with CRISPR-Cas9 for clinical use and suggest potential directions of the CRISPR-Cas9 system for future cancer therapy.

Hematopoietic stem cell transplantation (HSCT) is increasingly indicated for various malignant and non-malignant diseases. In the United Arab Emirates (UAE), patients that could benefit from the procedure commonly need to seek medical care abroad in view of the lack of a comprehensive HSCT facility that could offer the full spectrum of interventions and monitoring protocols. This comes with considerable challenges related to coverage and logistics of travel. It also limits the continuity of clinical care, and presents inconvenience to patients who come from a different cultural background. In this article, we share our experiences and lessons learned during the establishment of the first comprehensive adult and pediatric HSCT unit in the UAE that is designed to cater for local citizens and residents, as well as neighboring countries facing similar availability challenges.

In the United Arab Emirates (UAE), lung cancer (LC) was the third leading cause of deaths due to cancer in 2017. Around 80% of the patients in the UAE are diagnosed at a late stage, rendering the treatment less effective in improving survival outcomes. Lack of awareness of disease symptomatology, deficient screening initiatives, misdiagnosis, and delayed referral to the specialist are contributing factors for delayed diagnosis. Effective screening at a primary care setting can be crucial for early diagnosis, referral to specialists, and enhancing patient outcomes. It is important to establish screening and referral guidelines through which each suspected case can be identified and provided timely intervention. Although the international screening and referral pathway framework are comprehensive, several regional barriers need to be addressed before they can be adapted at the national level. A group of LC experts from the UAE deliberated on issues like delayed diagnosis of LC and strategic recommendations for overcoming the challenges. The discussion was based on the review of the published evidence, international and regional guidelines for screening and early diagnosis of LC. Herein, we present a guideline, endorsed by the esteemed panel of experts, for aiding early diagnosis and optimizing the management of LC in the UAE. Full article

Dihydropyrimidine dehydrogenase (DPD) is the major enzyme in the catabolism of 5-Fluorouracil (5-FU) and its prodrug capecitabine. We report cases from our institute with colorectal cancer who experienced severe toxicities to standard dose 5-FU based chemotherapy. DPYD gene sequencing revealed rare different polymorphisms that prompted dose adjustments of administered 5-FU and capecitabine. To our knowledge, this is the first case series looking at DPYD polymorphisms in the Saudi Arabian population. Full article
