Cancer Research in the Arab World: A review of publications from seven countries between 2000-2013

Introduction of Cancer Education Program in Secondary School Curriculum: Perceptions of Education Teachers and Policymakers in Oman

The prevalence of cancer is expected to increase worldwide for reasons related to a lack of awareness of cancer prevention, diagnosis, and treatment. Implementing cancer education programs in schools in the developing countries with similar demographic, economic, and health transition to that of Oman is crucial for enhancing students' cancer knowledge and promoting healthy behavior. This study aims to explore the perceptions of education, policymakers, and teachers regarding the inclusion of cancer education in secondary school curriculum. The study employed a qualitative method, conducting semi-structured interviews with ten education policymakers and ten school teachers. Interviews were audio recorded, transcribed, and analyzed verbatim and qualitatively using the framework approach. Three main themes have emerged: (1) perception of the importance of cancer education inclusion within the school curriculum, (2) the perception of cancer education implementation in schools, and (3) the perceived challenges of introducing cancer education in schools. Policymakers and teachers in Oman recognize the importance of cancer education in schools and emphasized the need to prioritize it due to the increasing prevalence of the disease and the belief that negative lifestyle habits played a role in its increased prevalence. Implementing cancer education programs in schools is essential in improving students' knowledge of cancer and health behaviors. Collaboration between the department of school health in ministry of education and in ministry of health and incorporating cancer education into different school activities can be beneficial. However, the perceived challenges of cancer education in schools include the decision on the priority of cancer education among other topics, the required procedures to introduce cancer education in schools, and the financial and logistics obligations of implementing cancer education programs. Therefore, addressing the financial and logistic requirements is essential to overcome the associated challenges for implementing cancer education programs within the school curriculum.

Impact of a comprehensive rehabilitation palliative care program on the quality of life of patients with terminal cancer and their informal caregivers: a quasi-experimental study

BACKGROUND

Palliative care schemes, which include pain management, symptom control, psychosocial support and rehabilitation, aim to boost patients' quality of life, ease the burden and anxiety of informal caregivers, and ultimately provide a comprehensive approach to enhance well-being during this challenging and sensitive period. This study aims to evaluate the impact of a comprehensive rehabilitation palliative care program on the quality of life of patients with terminal cancer and their informal caregivers.

METHODS

This quasi-experimental study, conducted from August 2023 to January 2024 at outpatient clinics affiliated with the Oncology Center at Mansoura University, Egypt, focused on cancer patients and their caregivers in the palliative care department. Employing pre- and post-test phases, data were gathered using a questionnaire, EORTC QLQ C30, Hospital Anxiety and Depression Scale, Short Form Health Survey, Caregiver Burden Inventory, and Beck Anxiety Inventory. The investigation evaluated a 16-week rehabilitation program comprising exercise, psychoeducation, individual counselling, and spiritual support. Exercises, led by a physiotherapist, targeted fatigue and stress through tailored aerobic and resistance training. Psychoeducation sessions aimed to bolster coping abilities, covering fatigue management and nutrition. Trained counsellors addressed spiritual and existential concerns. Personal advisory sessions were available for individual support. Caregivers received education on rehabilitation and palliative care protocols, ensuring comprehensive patient care.

RESULTS

The mean age for cancer patients was 65.79 ± 13.85. In contrast, the mean age for primary carers was 42.05 ± 11.15. The QOL for cancer patients during the pre-test phase was 77.8 ± 7.16 and rose to 87.34 ± 14.56 during the post-test phase. Additionally, the total anxiety level of patients before the rehabilitation palliative care program was conducted was 15.45 ± 3.05 compared to 6.12 ± 3.21 after the post test phase. Furthermore, the total depression levels of the patients during the pre-test phase were 20.89 ± 9.21. However, after implementing the rehabilitation palliative care program, it decreased to 15.5 ± 6.86. In regards to the total quality of life of informal caregivers, it was measured at 67.28 ± 32.09 before conducting the program. Nevertheless, it increased to 25.95 ± 40.29 after conducting it. Additionally, the total Caregiver Burden Inventory before implementing the program was 37.45 ± 25.7, and it decreased to 29.36 ± 16.4 after conducting it. Additionally, the total score on the Beck Anxiety Inventory decreased from 45.7 ± 4.3 during the initial testing phase to 17.35 ± 23.67.

CONCLUSION

The program for rehabilitation palliative care successfully achieved its goals by enhancing the overall quality of life for cancer patients and their caregivers. Additionally, it reduced the anxiety and depression levels among the patients, as well as the anxiety and caregiver burden among the caregivers. Continue research into the effectiveness of rehabilitation palliative care programs to identify best practices, improve existing programs, and expand access to these services.

In vitro biological studies and computational prediction-based analyses of pyrazolo[1,5-a]pyrimidine derivatives

There is a need for new pharmaceutical discoveries from bioactive nitrogenous derivatives due to the emergence of scourges, numerous pandemics, and diverse health problems. In this context, pyrazolo[1,5-a]pyrimidine derivatives 12a and 12b were synthesized and screened to evaluate their biological potentials in vitro as antioxidants, anti-diabetics, anti-Alzheimer's, anti-arthritics, and anti-cancer agents. Additionally, the computational pharmacokinetic and toxicity properties of the two pyrazolo[1,5-a]pyrimidines 12a and 12b were calculated and analyzed. The preliminary studies and results of this work represent the initial steps toward more advanced studies and define the bioactive chemical structure of pyrazolo[1,5-a]pyrimidine derivatives with the goal of exploring new drugs to address numerous health problems.

Arab Countries and Oncology Clinical Trials: A Bibliometric Analysis

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.

Cancer Research in Vulnerable Populations: A Call for Collaboration and Sustainability From MENAT Countries

PURPOSE

Cancer is a major burden across Middle East, North Africa, Türkiye (MENAT). Many MENAT countries experience multiple conflicts that compound vulnerabilities, but little research investigates the linkages between vulnerability and cancer research. This study examines the current level and the potential for cancer research among vulnerable populations in the MENAT region, aiming to provide direction toward developing a research agenda on the region's vulnerable populations.

METHODS

Expert-driven meetings were arranged among the 10 authors. After obtaining institutional review board approval, a self-administered online survey questionnaire was circulated to more than 500 cancer practitioners working in 22 MENAT countries.

RESULTS

Two hundred sixteen cancer practitioners across the MENAT region responded. Fifty percent of the respondents identified clinical research in vulnerable patients with cancer as a significant issue; 21.8% reported previous research experience that included vulnerable populations, and 60% reported encountering vulnerable populations in their daily clinical practice. The main barriers to conducting research were lack of funding (60%), protected time (42%), and research training (35%). More than half of the respondents believed that wars/conflicts constituted an important source of vulnerability. The most vulnerable cancer populations were the elderly, palliative/terminally ill, those with concomitant mental health-related issues, those with other chronic illnesses, and socioeconomically deprived patients.

CONCLUSION

Results support that a major effort is needed to improve cancer research among vulnerable cancer populations in the MENAT region. We call for interdisciplinary research that accounts for the region's unique, compounding, and cumulative forms of vulnerability. This cancer research agenda on different vulnerable populations must balance sociobehavioral studies that explore sociopolitical barriers to quality care and clinical studies that gauge and refine treatment protocols. Building a research agenda through collaboration and solidarity with international partners is prime time.

Challenges Facing Arab Researchers in Publishing Scientific Research: A Qualitative Interview Study

Background

Studies have shown an underrepresentation of researchers from lower- and middle-income countries (LMICs) in the research literature compared with their counterparts in high-income countries. We aimed to explore Arab researchers' challenges regarding conducting and publishing research in peer-reviewed journals.

Methods

We used a descriptive qualitative study design of semi-structured in-depth interviews. Using purposive sampling, we recruited participants from four Arab countries in the Middle East and North Africa. All interviews were recorded, transcribed, and translated to English if the original language was Arabic or French. We analyzed the transcripts using reflexive thematic analysis. Several authors independently coded the transcripts and agreed on the identified codes, themes, and subthemes.

Results

We performed 17 interviews: three from Egypt, six from Jordan, four from Morocco, and four from Sudan. Our participants' comments were divided into three broad categories with associated themes and subthemes. The first regards the conduct of research (themes of inadequate quality of research, insufficient research resources, and nonsuppurative research environment). The second category involves the publishing process (themes of poor scientific writing skills and difficulties navigating the publishing and peer-reviewed system). The third regards international collaborations and the final category recommends methods to address the challenges. Our recommendations include: enhancing the institutional research culture, increasing funding mechanisms, establishing mentoring programs and workshops on research methodology and scientific writing, and increasing the representation of LMICs on the editorial staff.

Conclusions

Identifying the challenges of Arab researchers in publishing original and quality research would guide programs tailored and targeted toward Arab scholars' needs.

The state of cancer research in fragile and conflict-affected settings in the Middle East and North Africa Region: A bibliometric analysis

Background

Cancer represents a disproportionate burden in LMICs, especially conflict-affected countries in the MENA region. Research output on cancer fails to match the growing burden in the region. This bibliometric study aims to examine the status and trends of cancer research in fragile and conflict-affected settings in the MENA region from 2000 to 2021, while also incorporating economic and demographic indicators as additional factors of analysis.

Methods

The Web of Science databases were searched for publications related to cancer research in Iraq, Lebanon, Libya, Palestine, Syria, and Yemen from January 1, 2000, to December 31, 2021. The retrieved publications were screened based on preset eligibility criteria and the final list was analyzed using the Bibliometrix Package in R to generate the annual scientific production and citations, journals, institutions, authors, collaborations, keywords, and title co-occurrence. Each country's annual scientific production was analyzed against its annual GDP per capita.

Results

A total of 4,280 documents met the inclusion criteria in this research. The annual number of publications revealed a significant increase over the past 20 years. These publications were mostly published in international journals that had impact factors rated in the 3rd or 4th quartiles. The overall contribution of researchers from Fragile and Conflict-Affected Settings (FCS) to cancer research was 6.5% of the MENA cancer research productivity, despite comprising around 23% of the total MENA region's population. Lebanon had the highest publication productivity at the country level, followed by Iraq and Syria. GDP per capita was not significantly correlated with cancer research across the countries under investigation. At the institutional level, the American University of Beirut was the most prolific institution and had the highest number of collaborations and the widest range of cooperative partners. Most first authors were male researchers. There is an interest in cancer expression, prevalence, diagnosis, and management in terms of commonly researched topics.

Conclusion

This study underscores the need for a concerted effort to improve cancer research outcomes in FCS, which can be achieved through targeted research, increased investment in research infrastructure and capacity-building initiatives, and greater regional and global collaboration.

Psychological distress and associated factors among Palestinian advanced cancer patients: A cross-sectional study

OBJECTIVE

There is limited research exploring the experiences of people living with advanced cancer in the Gaza Strip (GS), Palestine. Thus, this study aimed to determine the level of psychological distress, anxiety, and depression among advanced cancer patients in the GS and identify factors associated with a high level of distress.

MATERIALS AND METHODS

A secondary analysis was performed using primary data from a larger study focusing on supportive care needs in advanced cancer patients in GS. Three hundred sixty-one patients agreed to participate and filled out the Distress Thermometer (DT) and the Hospital Anxiety and Depression Scale (HADS). Multivariate logistic regression was conducted to identify factors associated with high distress levels.

RESULTS

Over two-thirds of advanced cancer patients (70.6%) reported a high level of distress. They also reported a significantly higher distress level than patients with early cancer (96.5 vs. 3.5%; p = 0.001). About 92.8% of participants reported depression and anxiety symptoms. Physical, emotional, and practical problems were the primary sources of distress. Breast cancer patients were more likely to have psychological distress than colon and stomach cancer patients. Newly diagnosed patients had a higher level of anxiety, depression, and distress than those who had a cancer diagnosis for an extended period.

CONCLUSION

Patients with advanced cancer in the GS exhibited a significantly higher level of psychological distress, depression and anxiety than patients with advanced cancer elsewhere. Efforts should be made to identify psychological distress as a routine part of oncology practice. Future research should further explore the causes of psychological distress in cancer patients in conflict zones and feasible mitigation strategies.

Sexual activity and cancer: A systematic review of prevalence, predictors and information needs among female Arab cancer survivors

INTRODUCTION

The objective of this review is to synthesise and present the best available evidence on the prevalence, predictors and information needs about sexual health among female Arab cancer survivors.

METHODS

The databases searched included MEDLINE, Embase and CINAHL from inception of the database until March 2020. The review was undertaken according to the JBI guidelines. Proportional meta-analysis using a random effects model was used for statistical pooling through JBI SUMARI.

RESULTS

Seven studies involving female Arab cancer survivors were included in the review. The overall prevalence of sexual dysfunction ranged from 16.7 to 67% (pooled estimate 51%, 95% CIs 21.7% to 80.2%). Dyspareunia and erectile dysfunction were the two main types of sexual dysfunction reported after diagnosis, and the overall prevalence ranged from 42.5% to 65% and 38% to 61%, respectively. The prevalence of vaginal dryness was ranged from 19.8% to 54.2%, and dyspareunia ranged from 22.2% to 65%. The lack of sexuality information and communication with health care providers (HCPs) was also reported in the included studies.

CONCLUSION

Cancer and its treatment may result in significant difficulties with sexual activity and sexual functioning among cancer survivor. Communication between the health care professionals and cancer survivors is essential to overcome this problem and improve the quality of life of female Arab cancer survivors.

Tobacco Research in the Eastern Mediterranean Region: A Scoping Review of Published Studies from Seven Countries

While surveillance on a global scale has been showing a decline in tobacco smoking in the past decade, rates in the Eastern Mediterranean Region (EMR) remained stable with some countries showing rising trends. This study aimed to analyze the landscape of tobacco research in the EMR, present data on publication trends, and identify research gaps and opportunities to guide future tobacco research in the region. We conducted a scoping review of tobacco research in seven countries from January 2000 to December 2013. Three hundred and forty eight studies were identified, the majority of which were published in international journals and in English language. There was an increase in publications over time, with a significant positive linear trend (p = 0.03). Descriptive cross-sectional and case-control studies were the most common study designs (67.0%), and only 8% were longitudinal studies. Papers that reported, in part or solely, on waterpipe tobacco smoking (WTS) constituted 25.6% of the total publication pool. Tobacco consumption was treated as an exposure variable in half of the papers and mostly in relation to cancer and cardiovascular diseases, as an outcome measure in 37.7%, and as a confounding variable in 14.7% of the papers. Studies that examined associations of tobacco with other behaviors (5.3%) were lacking. The scarcity of high-evidence tobacco research in the EMR, together with the relatively deficient data on WTS and associations with other factors warrant the need for discussions on research priority setting and guidance on funding allocations in the region.

Strengthening capacity for cancer research in conflict settings: key informant insights from the Middle East

Background

Management of cancer in the Middle East and North Africa (MENA) region is accompanied by multiple challenges including heterogeneous access to early detection and treatment options and limited implementation of national cancer control plans. Furthermore, protracted armed conflicts across the region have had dramatic effects, including disruption of healthcare systems and the migration of healthcare professionals. Strengthening capacity for cancer research has been identified as a key intervention to correct data poverty, inform policy, manage limited resources and improve health outcomes.

Objective

The main objective of this study is to gain insights into the landscape, barriers and enablers of cancer training, research and care in the MENA region.

Method

We utilised purposive sampling to interview 16 key informants from a diverse academic, medical and research background originating from countries affected by conflicts, such as Lebanon, and from active conflict zones including Iraq and Syria.

Results

The themes that emerged from the interviews focused on the barriers to cancer care, barriers to cancer research and training, strengths and importance of cancer research and training recommendations. The detrimental effect of conflict on cancer provision and research was a cross-cutting sub-theme disrupting cancer care provision and research due to unsafe environments, fragmented facilities, absence of drugs and migration of personnel. When asked about perceived optimal training format for cancer research, most informants recommended a post-graduate, face-to-face training focusing on cancer research methods and concepts.

Conclusion

This study offers a unique insight into the barriers affecting cancer research and capacity-strengthening priorities from oncologists and researchers working in conflict-affected areas of the MENA region. These data will form the base for future capacity-strengthening initiatives addressing specific regional challenges.

Translation and validation of the Arabic version of the quality of oncology nursing care scale (QONCS): Psychometric testing in three Arabic countries

BACKGROUND

In the Arab world, little is known about cancer patient's satisfaction with the care provided by the oncology nurses. The only explanation for this dearth of knowledge is lack of a specified, valid and reliable tool that can be utilized with all types of cancer. This regional study was conducted to translate and validate the Arabic version of quality of oncology nursing care scale (QONCS).

METHODS

Brislin's model of translation was used with a cross-sectional, cross-cultural and psychometric design. A convenience sample of 517 from three countries (Jordan, Oman and Egypt) completed the study's surveys.

RESULTS

The results indicated that the total QONCS-Ar was reliable with Cronbach's alpha 0.88 and 0.84, 0.87, 0.83, 0.89 and 0.86 for being supported and confirmed, with the religious and spiritual care, belonging, being valued and being respected domains respectively. Exploratory factor analysis supported the dimensional structure of the 34-item scale with five domains with Kaiser-Meyer-Oklin (KMO) measuring 0.872 and Bartlett's Test of Sphericity being significant (significant p<0.001) CONCLUSION: QONCS-Ar is a relatively short, valid, reliable and easy to use instrument that can be applied with all types of cancer, research and educational institutions in the Arabic region.

Mapping breast cancer journal publications in conflict settings in the MENA region: a scoping review

Background

Breast cancer is a major cause of cancer-related morbidity and mortality among women in the the Middle East and North Africa (MENA) region. Conflict and political instability in the region may affect medical research output, including that on breast cancer. This scoping review aims to systematically identify and map breast cancer publications across different stages of the cancer care pathway and across conflict-affected countries within the MENA region. The findings of this work will highlight the impact of conflict on cancer research that could be mitigated with the proper contextualised capacity strengthening intervention.

Methods

We followed the PRISMA-Scr methodology. We searched for peer-reviewed publications on topics related to breast cancer in 11 databases: Medline, PubMed, EMBASE, Web of Science, PROQUEST, CINAHL, Global Index Medicus, Arab World Searches Complete, Popline, Scopus and Google Scholar using both controlled vocabulary and keywords. Publication abstracts and full-text versions were screened for duplicates and included in our study based on pre-specified eligibility criteria: focused on breast cancer, related to the specific country of analysis and human or health system studies. We used a structured data extraction form to extract information related to the article, its methodology and the cancer care pathway being studied.

Results

A total of 19,215 citations were retrieved from our search. After removing duplicates, a total of 8,622 articles remained. Title and abstract screening retained 1,613 articles. Publications with first author affiliations to Turkey were consistently the highest across all categories of the cancer care pathway. Trends show an increase in articles from Lebanon, Jordan and Palestine after 2015. Early exploratory and epidemiological studies represented the majority of breast cancer research, followed by policy and implementation research and lastly experimental research. Most research conducted followed an observational study design. Important gaps were identified in the research output related to advanced breast cancer and palliative care (Libya, Syria and Yemen), mental health (Libya), and knowledge and education of breast cancer (Libya and Syria).

Conclusion

This scoping review has identified key areas in breast cancer research that lack significant research activity in conflict MENA settings. These areas, including but are not limited to palliative care, mental health, and education, can be prioritised and developed through regional collaboration and contextualised capacity strengthening initiatives.

Research Capacity and Training Needs for Cancer in Conflict-Affected MENA Countries

Background

The global cancer burden is disproportionately greater in low- and middle-income countries, including those affected by conflict in the Middle East and North Africa (MENA) region. Contributing factors include inadequate control of risk factors plus limited surveillance and treatment options. Weak healthcare infrastructure may be further compounded by the conflict prevalent in multiple MENA countries. Improved cancer surveillance, research, and capacity strengthening are essential for implementing cancer control plans in the MENA region, requisite for reducing the disproportionate cancer burden.

Aims

This article aims to understand the barriers to cancer research and training in conflict-affected MENA countries, and to identify opportunities for developing capacities for reliable cancer research strategies.

Methods

This study employs a mixed-method approach utilizing an online questionnaire with open and close ended questions targeting oncologists and cancer researchers in conflict-affected MENA countries. For open-ended questions, we performed a qualitative content analysis to identify thematic barriers.

Results

Forty-eight respondents, mostly Medical and Radiation Oncologists, completed the questionnaire. The most significant training needs were conducting clinical, basic, and qualitative cancer research. The most prominent barriers identified were insufficient training in data analysis and research design (77% and 75% of respondents, respectively) and insufficient institutional and government funding (94% and 85%, respectively). For the qualitative data, we organized the barriers into six themes, the most common was the lack of research infrastructure (28%).

Conclusions

Despite an escalating cancer burden, conflict-affected MENA countries are lagging in knowledge production and implementation of evidence-based cancer research. Novel modes of knowledge transmission and collaboration across geographical and political boundaries are sorely needed. Based on our study, we recommend developing innovative and accessible training opportunities focusing on developing basic, clinical, and qualitative research skills. Research capacity-strengthening initiatives should encourage the investigation of context-specific research questions with the potential to make a meaningful impact on cancer control in the region.

Epidemiology of Different Types of Cancers Reported in Basra, Iraq

Objectives

This study aimed to report the incidence and pattern of various types of cancers and their distribution across various demographic groups in Basra, Iraq.

Methods

Cancer cases recorded during 2017 at the Basra Cancer Control Centre, the Department of Pathology and Forensic Medicine, the Basra Oncology and Hematology Centre, the Basra Children’s Hospital and at private laboratories were included in the study. Patients’ records were analysed for information related to age, gender, residence and type of cancer. Incidences for different geographical regions and distribution of incidences across age groups were recorded as percentages. The mean age was recorded for patients of different genders and age groups. Incidence rates per 100,000 were calculated for different types of cancer.

Results

A total of 2,163 cancer cases were identified of which 2,020 were in adults (93.4%) and 143 were in children (6.6%). Among adults, most cancers were found in females (59%). Patients’ mean age at diagnosis was 51.4 ± 19.6 years for adults and 6.4 ± 4.23 years for children. Cancer incidence rates per 100,000 people increased with age. Breast cancer was the most frequent cancer type found in adult females, with an incidence rate of 60.64 per 100,000 people. The most common types of cancer found in adult males were urinary bladder and lung and bronchus cancers; leukaemia was the most common cancer in children.

Conclusion

The findings from this study can be used for predicting cancer epidemiology in Basra, Iraq, and to identify subsets of the population at high risk of cancer incidence. This information will help healthcare providers to adequately respond to the demands of diagnosis, treatment and palliative care for such patients.

Correlation between breast cancer and lifestyle within the Gulf Cooperation Council countries: A systematic review

BACKGROUND

In the six Gulf Cooperation Council countries (GCCCs), Bahrain, Saudi Arabia, Kuwait, Oman, Qatar and the United Arab Emirates, breast cancer (BC) is the greatest cause of cancer incidence and mortality. Obesity and physical inactivity are established risk factors for BC globally and appear to be more of a problem in high income countries like the GCCCs.

AIM

To determine whether obesity and physical inactivity are associated with BC incidence in the GCCCs using the United Kingdom as a comparator.

METHODS

This systematic review was carried out according to PRISMA guidelines. A cancer registry and a statistical data search was done to identify the BC incidence over the past two decades and the prevalence of obesity and physical inactivity in the GCCCs. Additionally, a systematic search of the databases, MEDLINE, Web of Science, and PubMed between 1999 and 2019 was performed to determine whether obesity and physical inactivity are risk factors for BC in the GCCCs. All papers were critically appraised according to their research methods and were assessed for quality and risk of bias.

RESULTS

BC was the top malignancy in each GCC country. Women tended to be diagnosed with BC at a younger age than women in the United Kingdom. The greatest 10-year increase in BC incidence was seen in Saudi Arabia (54.2%), approximately seven times the rate of increase seen in the United Kingdom (7.6%). The prevalence of obesity and physical inactivity was greater in all the GCCCs in comparison to the United Kingdom. A total of 155 full studies were reviewed of which 17 were included. Of those, eight looked at the prevalence of obesity and physical inactivity in the Gulf States and nine looked at these as risk factors for BC. Only one study found an association between BC and obesity (odds ratio = 2.29). No studies looked solely at the link between physical inactivity and BC.

CONCLUSION

The prevalence of obesity and physical inactivity was high within the GCCCs, but the majority of the included studies found no positive correlation between obesity or physical inactivity and BC. A high proportion of women in this study were pre-menopausal which could contribute to the negative findings.

Single-Institution Experience with Selective Internal Radiation Therapy (SIRT) for the Treatment of Primary and Secondary Hepatic Tumors

Purpose: We aim to provide results of the real-world experience of a single center in Lebanon on the use of radioembolization to treat liver-only or liver-dominant tumors. 

Methods: This retrospective review included patients who were evaluated for radioembolization between January 2015 and June 2017 and who had a lung shunt fraction of 20% or less. Tumor responses were determined using the response evaluation criteria in solid tumors (RECIST).

Results: Of the 23 Arab patients with a median age of 64 years (range, 36-87 years), eight had hepatocellular carcinoma, four had cholangiocarcinoma, and 11 had liver-only or liver-dominant metastases from other primary cancers. Most (n=17) had multifocal lesions, and 13 had a history of branched (n=8) or main (n=5) portal vein thrombosis. When appropriate, the gastroduodenal artery and middle hepatic artery were embolized for consolidation of radiotherapy; 18 patients required arterial coil occlusion, two had their cystic artery occluded, and one developed cholecystitis, which was successfully treated with antibiotics and supportive care. Another patient developed a post-radioembolization complication-a peptic ulcer unrelated to arterial reflux of microspheres because both the gastroduodenal and right gastric arteries were occluded. The median time to progression was seven months (range, 3-36 months), and median overall survival from radioembolization was 12 months (range, 3-40 months). Tumor responses included five complete responses, 13 partial responses, one stable disease, and four cases of progressive disease. 

Conclusion: Performing radioembolization in a non-referral, private center in Lebanon resulted in good patient outcomes with few complications.

Familial/inherited cancer syndrome: a focus on the highly consanguineous Arab population

The study of hereditary cancer, which accounts for ~10% of cancer cases worldwide is an important subfield of oncology. Our understanding of hereditary cancers has greatly advanced with recent advances in sequencing technology, but as with any genetic trait, gene frequencies of cancer-associated mutations vary across populations, and most studies that have located hereditary cancer genes have been conducted on European or Asian populations. There is an urgent need to trace hereditary cancer genes across the Arab world. Hereditary disease is particularly prevalent among members of consanguineous populations, and consanguineous marriages are particularly common in the Arab world. There are also cultural and educational idiosyncrasies that differentiate Arab populations from other more thoroughly studied groups with respect to cancer awareness and treatment. Therefore, a review of the literature on hereditary cancers in this understudied population was undertaken. We report that BRCA mutations are not as prevalent among Arab breast cancer patients as they are among other ethnic groups, and therefore, other genes may play a more important role. A wide variety of germline inherited mutations that are associated with cancer are discussed, with particular attention to breast, ovarian, colorectal, prostate, and brain cancers. Finally, we describe the state of the profession of familial cancer genetic counselling in the Arab world, and the clinics and societies dedicated to its advances. We describe the complexities of genetic counselling that are specific to the Arab world. Understanding hereditary cancer is heavily dependent on understanding population-specific variations in cancer-associated gene frequencies.

Review of Non-Communicable Disease Research Activity in Kuwait: Where is the Evidence for the Best Practice?

Background:

Kuwait, a small country in the Middle East, is now facing rapid development, with non-communicable diseases (NCDs) accounting for the majority of deaths.

Objectives:

In this study, we review trends in NCD research productivity in Kuwait and examine to what extent it is aligned with disease burden.

Methods:

Systematic mapping of NCD papers produced between January 2000 and December 2013 yielded 893 publications. These were defined according to study design, study focus, and risk factors examined. Research gaps were assessed by examining disparities between literature produced and cause-specific proportional mortality rates (PMR) and disability-adjusted life years (DALYs).

Findings:

While annual publication rates increased more than two-fold during the study period, many of the study methodologies were descriptive (58%). Only 2.6% were based on high-evidence interventional studies. Cancer, CVD, and diabetes featured in 38.1%, 15.1%, and 9.2% of the publications, respectively. Compared to PMR and DALYs, there was a surplus of cancer research, most of which were laboratory-based studies (27.6%) or of the case-report/case-series study type (26.5%). Smoking was more likely to be addressed in relation to CVD (32.6%) than diabetes (6.1%) or cancer (2.1%). Physical inactivity was mostly examined in its relation to diabetes (14.6%), with negligible representation in the remaining study focus (range 0.3% to 2.2%).

Conclusion:

NCD research production in Kuwait is not aligned with disease burden or health priorities. We recommend a coordinated action between funding agencies, universities, and researchers in Kuwait to guide development of a comprehensive research agenda that is responsive to the country’s emerging needs.
