ABSTRACT

BReast CAncer (BRCA)1 and BRCA2 gene pathogenic variants account for most hereditary breast cancers (BC). Identification of BRCA mutations can significantly influence both prognosis and treatment outcomes. Furthermore, it enables the identification of individuals who are at heightened risk of developing BC due to inherited genetic mutations. Many developing countries rely on western guidelines for BRCA testing and BC management; however, there exist wide disparities in the prevalence of risk factors, availability of medical resources, and practice patterns. Guidelines tailored to specific regions can help mitigate healthcare variations, promote consistency in treatment, and aid healthcare providers in identifying effective therapies for improving patient outcomes. Hence, oncologists from the Gulf Cooperation Council (GCC) congregated virtually in March 2023 and reviewed existing data on the epidemiology of BC, BRCA mutations, practices and challenges associated with BRCA testing and management of BRCA mutated early-stage BC in the GCC region. They also provided insights on the real-world diagnostic and treatment practices and challenges in the GCC region in the BRCA-mutated early-stage BC domain and suggested some variations to international guidelines to aid their uptake in this region.

ABSTRACT

Background: The prevalence of lung cancer in the Middle East and Africa (MEA) region has steadily increased in recent years and is generally associated with a poor prognosis due to the late detection of most of the cases. We explored the factors leading to delayed diagnoses, as well as the challenges and gaps in the early screening, detection, and referral framework for lung cancer in the MEA. Methods: A steering committee meeting was convened in October 2022, attended by a panel of ten key external experts in the field of oncology from the Kingdom of Saudi Arabia, United Arab Emirates, South Africa, Egypt, Lebanon, Jordan, and Turkey, who critically and extensively analyzed the current unmet needs and challenges in the screening and early diagnosis of lung cancer in the region. Results: As per the experts' opinion, lack of awareness about disease symptoms, misdiagnosis, limited screening initiatives, and late referral to specialists were the primary reasons for delayed diagnoses emphasizing the need for national-level lung cancer screening programs in the MEA region. Screening guidelines recommend low-dose computerized tomography (LDCT) for lung cancer screening in patients with a high risk of malignancy. However, high cost and lack of awareness among the public as well as healthcare providers prevented the judicious use of LDCT in the MEA region. Well-established screening and referral guidelines were available in only a few of the MEA countries and needed to be implemented in others to identify suspected cases early and provide timely intervention thus improving patient outcomes. Conclusions: There is a great need for large-scale screening programs, preferably integrated with tobacco-control programs and awareness programs for physicians and patients, which may facilitate higher adherence to lung cancer screening and improve survival outcomes.

ABSTRACT

Lung cancer poses a global health challenge and stands as the leading cause of cancer-related deaths worldwide. However, its incidence, mortality, and characteristics are not uniform across all regions worldwide. Understanding the factors contributing to this diversity is crucial in a prevalent disease where most cases are diagnosed in advanced stages. Hence, prevention and early diagnosis emerge as the most efficient strategies to enhance outcomes. In Western societies, tobacco consumption constitutes the primary risk factor for lung cancer, accounting for up to 90% of cases. In other geographic locations, different significant factors play a fundamental role in disease development, such as individual genetic predisposition, or exposure to other carcinogens such as radon gas, environmental pollution, occupational exposures, or specific infectious diseases. Comprehensive clinical and molecular characterization of lung cancer in recent decades has enabled us to distinguish different subtypes of lung cancer with distinct phenotypes, genotypes, immunogenicity, treatment responses, and survival rates. The ultimate goal is to prevent and individualize lung cancer management in each community and improve patient outcomes.

ABSTRACT

Proton pump inhibitors (PPIs) are commonly used in cancer patients, but their impact on treatment outcomes in multiple myeloma (MM) patients remains unclear. This study investigated the association of PPI use with survival and adverse effects in MM patients across three randomized-control trials initiating daratumumab, lenalidomide, or bortezomib combination treatments. Cox proportional hazard analysis and logistic regression were employed to assess the associations with treatment outcomes, while adjusting for age, sex, weight, MM international staging system stage, ECOG-performance status, comorbidity count, and presence of gastrointestinal disorders. Pooled data involving 1804 patients revealed that 557 (32%) used PPIs at baseline. PPI use was independently associated with worse overall survival (adjusted HR [95% CI] 1.32 [1.08-1.62], P = 0.007) and grade ≥ 3 adverse events (adjusted OR [95% CI] 1.39 [1.03-1.88], P = 0.030). However, the association with progression-free survival did not reach statistical significance (adjusted HR [95% CI] 1.14 [0.97-1.33], P = 0.112). Findings were consistent across trials and treatment arms. PPI use was identified as a negative prognostic factor in MM patients, potentially enhancing clinical decisions regarding its use. Further research is needed to fully comprehend the impacts and safety of PPI use in MM patients.

ABSTRACT

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.

ABSTRACT

We herein report a case involving a woman with metastatic human epidermal growth factor receptor 2 (HER-2)-positive breast cancer (BC) who became pregnant while undergoing active anticancer therapy with Trastuzumab-Pertuzumab for her advanced BC disease at our institution. To our knowledge, this is the first reported case of pregnancy and successful delivery in a stage IV BC patient during anticancer therapy. A multidisciplinary approach for such a complex case is a must to evaluate the mother's medical condition by an experienced oncology team along with a maternal-fetal team, with support from a psychiatric and psychological evaluation for the mother. The use of effective contraception during anticancer therapy is essential to avoid such a scenario.

ABSTRACT

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.

ABSTRACT

Background: Prostate cancer remains a major public health challenge in the Arab world with few population-based screening programmes, a high incidence of advanced disease at diagnosis, and limited patient access to sub-specialist care. A large number of patients diagnosed with prostate cancer use the (World Wide Web) internet to learn more about the disease and treatment options; however, material in the Arabic language is scarce. This study aims to objectively assess the quality and reliability of the information on YouTube™, which is the most globally used video platform, pertaining to prostate cancer videos published in Arabic. Methods: A total of 100 videos were identified by searching specific keywords in Arabic (Prostate cancer, prostate cancer treatment and prostate). Retrieved videos were analysed and categorised into four groups according to content as useful, misleading, personal experience, or irrelevant. Useful videos were assessed using the global quality scale (GQS) as a validated measure of quality, which is graded on a 5-point Likert scale, with 1 representing poor quality and 5 representing excellent quality. The modified DISCERN tool was used as a measure of reliability. The tool has a potential total score of 5 points, with higher scores indicating higher reliability. Results: Most of the speakers in these videos identified themselves as health workers (77%). Only 8% of the videos sources were hospital or medical organisations. Of the 100 retrieved videos, 86% were found to have useful content, while 14% were found to be misleading or irrelevant. The median GQS score of the useful videos was 4 (IQR: 4-5), while the median modified DISCERN tool was 4 (IQR: 3-4). Conclusion: To our knowledge, this is the first in-depth study to objectively assess the quality and reliability of information pertaining to prostate cancer in the Arabic language on YouTube™. More efforts are needed to improve the quality of prostate cancer educational materials and videos in the Arabic language on YouTube™. Patient focus groups are planned as the next step to address the information gap for patients with prostate cancer in the Arabic language.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

The recently emerged novel coronavirus, "severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)," caused a highly contagious disease called coronavirus disease 2019 (COVID-19). It has severely damaged the world's most developed countries and has turned into a major threat for low- and middle-income countries. Since its emergence in late 2019, medical interventions have been substantial, and most countries relied on public health measures collectively known as nonpharmaceutical interventions (NPIs). We aimed to centralize the accumulative knowledge of NPIs against COVID-19 for each country under one worldwide consortium. International COVID-19 Research Network collaborators developed a cross-sectional online survey to assess the implications of NPIs and sanitary supply on the incidence and mortality of COVID-19. The survey was conducted between January 1 and February 1, 2021, and participants from 92 countries/territories completed it. The association between NPIs, sanitation supplies, and incidence and mortality were examined by multivariate regression, with the log-transformed value of population as an offset value. The majority of countries/territories applied several preventive strategies, including social distancing (100.0%), quarantine (100.0%), isolation (98.9%), and school closure (97.8%). Individual-level preventive measures such as personal hygiene (100.0%) and wearing facial masks (94.6% at hospitals; 93.5% at mass transportation; 91.3% in mass gathering facilities) were also frequently applied. Quarantine at a designated place was negatively associated with incidence and mortality compared to home quarantine. Isolation at a designated place was also associated with reduced mortality compared to home isolation. Recommendations to use sanitizer for personal hygiene reduced incidence compared to the recommendation to use soap. Deprivation of masks was associated with increased incidence. Higher incidence and mortality were found in countries/territories with higher economic levels. Mask deprivation was pervasive regardless of economic level. NPIs against COVID-19 such as using sanitizer, quarantine, and isolation can decrease the incidence and mortality of COVID-19.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Early Onset Colorectal cancer (EOCRC) incidence is increasing at an alarming pace. An increase of 90% in colon cancer and 124% in rectal cancer is expected by 2030. Patients with EOCRC are not receiving additional attention compared to older patients despite having a unique molecular pattern, majority of cases are sporadic, and related short- and long-term treatment and disease complications. The current management and screening guidelines have been constructed from studies on late onset CRC. Plethora of studies are ongoing to understand this disease entity in order to construct a tailored prevention, detection and management plans. While waiting for a better understanding of the disease, efforts should be directed toward improving the quality of care across the cancer continuum. Here we aim to address the challenges faced by EOCRC patients across the cancer continuum. This will facilitate directing future efforts and research toward construction of a personalized and precise guidelines.

ABSTRACT

Background: Gastric cancer (GC) is the fourth most common cancer worldwide, characterized by multifactorial pathogenesis and a heterogeneous geographic distribution. The complexity of this malignancy has evolved, with environmental and genetic factors and treatment strategies being more studied. Aims: We aimed to group and organize the clinicopathological and epidemiological features of GC in the Arab World and compare with data from Western countries. Methods: To obtain the highest number of topic-related articles, an extensive electronic search was conducted in the PubMed MEDLINE and Cochrane databases up to March 2022 using Boolean operators with a combination of keywords and MeSH terms. A total of 42 articles were retained after screening in accordance with the objectives of the study. The estimated age-standardized incidence rates in the Arab World were collected from the GLOBOCAN 2020 database. Results: A total of 46 articles were retrieved from 11 countries in the Arab World. Epidemiological elements were collected, especially tumour attributes, risk factors and population characteristics, in addition to some therapeutic strategies. Results were regrouped by theme and then organized in tables and charts, allowing a global and regional approach to the subject. Conclusion: This review shows that the Arab World is considered a low-rate GC incidence region, presenting almost the same tumour characteristics as the Western countries. The lack of GC data in the Arab World should trigger a rise in research on this type of malignancy to better understand the subject.

ABSTRACT

Papillary renal cell carcinoma (PRCC) is a less common subtype of kidney cancer and is typically more resistant to systemic treatments. This report describes a patient with metastatic type II PRCC who experienced two complete responses (CR) to the tyrosine kinase inhibitor (TKI) sunitinib. The patient remains on sunitinib with durable control of the disease. To the best of our knowledge, this is the first case of metastatic type II PRCC with CR to sunitinib.
