Smoking cessation counselling patterns in cancer patients - survey of Lebanese physicians.

Introduction: Tobacco smoking is a known risk factor for cancer development and smoking cessation can lower this risk and improve outcomes in some cancer patients. Despite that, many cancer patients do not quit smoking after a cancer diagnosis, and smoking cessation counselling is still not routinely provided in cancer care. The aim of this study is to examine patterns in smoking cessation counselling to cancer patients by their treating physicians. Methods: A self-administered, web-based (mobile-friendly), anonymous questionnaire was developed on LimeSurvey and sent by e-mail to Lebanese physicians of different specialties between June 2020 and January 2022. Data were analysed using SPSS and associations between the different items were determined using the χ2 test. Results: A total of 146 physicians filled out the questionnaire. Almost all physicians ask cancer patients about their smoking status, but only 45.9% provide smoking cessation counselling, and only 24% refer patients to smoking cessation counselling programs. Only 27.4% of all respondents have received formal smoking cessation training, and only 27.4% feel capable of providing smoking cessation counselling in their clinic. Specifically, family medicine physicians were more likely to provide smoking cessation counselling in the clinic (69%), more likely to refer patients to a smoking cessation counselling program (44%), and more likely to have received formal smoking cessation counselling training (67%) and more likely to feel capable of providing smoking cessation counselling (93%). Lack of training, lack of knowledge of available programs and the lack of availability of enough programs are leading obstacles contributing to low rates of smoking cessation counselling in cancer patients as reported by the physicians. Conclusion: Our data reveals a deficiency in smoking cessation counselling and referral of cancer patients to smoking cessation counselling programs in our region. This highlights the need for dedicated smoking cessation counselling training for practicing physicians and physicians in training.

Discordance in Recommendation Between Next-Generation Sequencing Test Reports and Molecular Tumor Boards in India.

PURPOSE: Accurate understanding of the genomic and transcriptomic data provided by next-generation sequencing (NGS) is essential for the effective utilization of precision oncology. Molecular tumor boards (MTBs) aim to translate the complex data in NGS reports into effective clinical interventions. Often, MTB treatment recommendations differ from those in the NGS reports. In this study, we analyze the discordance between these recommendations and the rationales behind the discordances, in a non-high-income setting, with international input to evaluate the necessity of MTB in clinical practice. METHODS: We collated data from MTB that were virtually hosted in Chennai, India. We included patients with malignancies who had NGS reports on solid tissue or liquid biopsies, and excluded those with incomplete data. MTB forms and NGS reports of each clinical case were analyzed and evaluated for recommendation concordance. Concordance was defined as an agreement between the first recommendation in the MTB forms and the therapeutic recommendations suggested in the NGS report. Discordance was the absence of the said agreement. The rationales for discordance were identified and documented. RESULTS: Seventy MTB reports were analyzed with 49 cases meeting the inclusion criteria. The recommendation discordance was 49% (24 of 49). Discordant recommendations were mainly due to low level of evidence for the drug (75% of cases). CONCLUSION: The discordance between MTB and NGS vendor recommendations highlights the clinical utility of MTB. The educational experiences provided by this initiative are an example of how virtual academic collaborations can enhance patient care and provider education across geographic borders.

Esophageal cancer: a twenty-four-year experience at a tertiary care center with an evaluation of the prognostic significance of the neutrophil-lymphocyte ratio.

BACKGROUND: A high neutrophil-lymphocyte ratio (NLR) may be associated with worse survival in esophageal cancer (EC). Our aims were to describe the demographic and clinical data of EC in a tertiary referral center in Lebanon and to determine the prognostic value of NLR. METHODS: A retrospective cohort study based on chart review of patients diagnosed with EC was conducted at the American University of Beirut Medical Center (AUBMC). The demographic characteristics, clinical presentation and outcomes were described and compared between squamous cell carcinomas (ESCC) and adenocarcinomas (EAC). Data about esophageal cancer incidence were obtained from the National Cancer Registry, the Ministry of Public Health and GLOBOCAN 2020. Cox regression analysis was performed to determine whether the NLR is an independent predictor of survival, using variables based on clinical knowledge and previously established data. RESULTS: 110 patients were diagnosed with EC, which was the least common among other gastrointestinal malignancies. Our follow up rates reached 86.4%. The median survival was 9 months (IQR 3-25.5.) and was comparable between ESCC (median of 7 months, IQR 2-25) and EAC (median of 9 months, IQR 3-26.3), p = 0.803. Advanced stage was associated with a worse prognosis (p = 0.037). The mean NLR(±SD) was 5.20 ± 6.8, with no significant difference between EAC and ESCC (4.5 ± 3.4 vs. 5.9 ± 9.2, p = 0.420) or between early or advanced stages (5.4 ± 8.1 vs. 4.7 ± 6.8, p = 0.732). The area under the curve for the NLR was 0.560 (95% CI: 0.374-0.746, p = 0.488). After adjusting for age, gender, TNM staging and grading, cox regression analysis showed that an increased NLR was a significant predictor of mortality, with an adjusted hazard ratio of 1.095 (p = 0.011). CONCLUSION: EC is quite uncommon in Lebanon despite a high prevalence of smoking and obesity. Advanced stage and high NLR were associated with a negative prognostic value.

Incidental intra-abdominal synovial sarcoma.

Intra-abdominal synovial sarcomas are a rare type of soft tissue sarcomas that arise in the soft tissues of the abdominal cavity. They account for less than 1% of all primary synovial sarcoma cases. We report a case of a male patient in his early 30s who presented to the hospital with abdominal pain of 2 weeks duration. On examination, a mass was felt in the left mid-abdomen. MRI revealed a 12.7 cm×8.2 cm×8.6 cm soft tissue mass on the mesentery of the jejunum. The patient underwent surgical resection of the tumour, and the final pathology was synovial sarcoma, pT2b, grade 3.

Quality and reliability of YouTube videos in Arabic as a source of patient information on prostate cancer.

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.

Redefining Cancer Research Priorities in Low- and Middle-Income Countries in the Post-COVID-19 Global Context: A Modified Delphi Consensus Process.

PURPOSE: The post-COVID-19 funding landscape for cancer research globally has become increasingly challenging, particularly in resource-challenged regions (RCRs) lacking strong research ecosystems. We aimed to produce a list of priority areas for cancer research in countries with limited resources, informed by researchers and patients. METHODS: Cancer experts in lower-resource health care systems (as defined by the World Bank as low- and middle-income countries; N = 151) were contacted to participate in a modified consensus-seeking Delphi survey, comprising two rounds. In round 1, participants (n = 69) rated predetermined areas of potential research priority (ARPs) for importance and suggested missing ARPs. In round 2, the same participants (n = 49) rated an integrated list of predetermined and suggested ARPs from round 1, then undertook a forced choice priority ranking exercise. Composite voting scores (T-scores) were used to rank the ARPs. Importance ratings were summarized descriptively. Findings were discussed with international patient advocacy organization representatives. RESULTS: The top ARP was research into strategies adapting guidelines or treatment strategies in line with available resources (particularly systemic therapy) (T = 83). Others included cancer registries (T = 62); prevention (T = 52); end-of-life care (T = 53); and value-based and affordable care (T = 51). The top COVID-19/cancer ARP was strategies to incorporate what has been learned during the pandemic that can be maintained posteriorly (T = 36). Others included treatment schedule interruption (T = 24); cost-effective reduction of COVID-19 morbidity/mortality (T = 19); and pandemic preparedness (T = 18). CONCLUSION: Areas of strategic priority favored by cancer researchers in RCRs are related to adaptive treatment guidelines; sustainable implementation of cancer registries; prevention strategies; value-based and affordable cancer care; investments in research capacity building; epidemiologic work on local risk factors for cancer; and combatting inequities of prevention and care access.

Randomised controlled trials evaluating anticancer therapies in haematological cancers: an overview of global research activity.

Background: Design, results, and interpretation of oncology randomised controlled trials (RCTs) have changed substantially over the past decade. In this study, we describe all RCTs evaluating anticancer therapies in haematological cancers published globally during 2014-2017 with comparisons with solid tumours RCTs. Methods: A PubMed literature search identified all phase 3 RCTs of anticancer therapy for haematological cancers and solid tumours published globally during 2014-2017. Descriptive statistics, chi-square tests and the Kruskal-Wallis test were used to compare RCT design results, and output between haematological cancers and solid tumours as well as for different haematological cancer subtypes. Results: 694 RCTs were identified; 124 in haematological cancers and 570 in solid tumours. Overall survival (OS) was the primary endpoint in only 12% (15/124) of haematological cancer trials compared to 35% (200/570) in solid tumours (p < 0.001). Haematological cancer RCTs evaluated the systemic novel therapy more often than the solid tumour RCT (98% versus 84%, p = 0.002). Use of surrogate endpoints like progression-free survival (PFS) and time to treatment failure (TTF) were more common in haematological cancers than solid tumours (47% versus 31%, p < 0.001). Within haematological cancers, the use of PFS and TTF was more prevalent in chronic lymphocytic leukaemia and multiple myeloma as compared to others (80%-81% versus 0%-41%, p < 0.001). Seventy-eight percent of haematologic trials were funded by industry as compared to 70% of solid tumour trials. Only 4% (5/124) of haematologicalcancer trials were led by investigators in upper-middle and lower-middle-income countries as compared to the 9% of solid tumour trials. Conclusion: The fact that only 12% of haematological cancer RCTs are designed to show improvements in OS is of grave concern for the field and the care of future patients. This is further compounded by the highly prevalent use of alternative primary endpoints that are rarely valid surrogates for OS in haematological cancers.

The challenges of international collaboration in conflict and health research: experience from the Research for Health in Conflict-Middle East and North Africa (R4HC-MENA) partnership.

BACKGROUND: Healthcare is a basic human right extending across all humanitarian contexts, including conflict. Globally, two billion people are living under conditions of insecurity and violent armed conflict with a consequent impact on public health. Health research in conflict-affected regions has been recognised as important to gain more understanding of the actual needs of such populations, to optimise healthcare delivery, as well as to inform advocacy and policy change. International collaborative research maximises the resources and skills available for dealing with global health issues, builds capacity and endeavours to ensure the research reflects real needs of the populations. Under the UK's Global Challenge Research Fund in 2017 a number of such international programs were created including the Research for Health in Conflict-Middle East and North Africa (R4HC-MENA) partnership to build capacity in conflict and health research as well as study specific areas, namely noncommunicable diseases in conflict (cancer & mental health) and the political economy of health in conflict. METHODS: A qualitative study using semi-structured online interviews was conducted to explore researchers' and stakeholders' perspectives on the R4HC-MENA programme over its lifetime from 2017 to 2021. It aimed to understand the factors that influenced and accelerated international collaboration within the R4HC-MENA programme on conflict and health research, and to provide deeper insights into the implementation of the programme. Data collection was conducted from March 2022 to June 2022. Purposive and snowball sampling techniques were used for participant recruitment. Thematic analysis was applied for data analysis. RESULTS: Twelve researchers/stakeholders participated in this study: four men and eight women. Four main themes were generated: Theme 1: Network building (personal and institutional levels); Theme 2: Hierarchies and power dynamics (power imbalance between different academic status, genders and institutions); Theme 3: Communication challenges; Theme 4: Career development (management, leadership, research, and teaching skills). CONCLUSIONS: This study provided preliminary insights into perspectives on international collaboration in a major international programme of research on conflict and health. Several key challenges and outputs were generated by the researchers in this study. The findings are important for further developing effective strategies to tackle the challenge of power imbalance and ineffective communication in international research collaborations.

Allocation of authorship and patient enrollment among global clinical trials in oncology.

BACKGROUND: Oncology randomized controlled trials (RCTs) are increasingly global in scope. Whether authorship is equitably shared between investigators from high-income countries (HIC) and low-middle/upper-middle incomes countries (LMIC/UMIC) is not well described. The authors conducted this study to understand the allocation of authorship and patient enrollment across all oncology RCTs conducted globally. METHODS: A cross-sectional retrospective cohort study of phase 3 RCTs (published 2014-2017) that were led by investigators in HIC and recruited patients in LMIC/UMIC. FINDINGS: During 2014-2017, 694 oncology RCTs were published; 636 (92%) were led by investigators from HIC. Among these HIC-led trials, 186 (29%) enrolled patients in LMIC/UMIC. One-third (33%, 62 of 186) of RCTs had no authors from LMIC/UMIC. Forty percent (74 of 186) of RCTs reported patient enrollment by country; in 50% (37 of 74) of these trials, LMIC/UMIC contributed <15% of patients. The relationship between enrollment and authorship proportion is very strong and is comparable between LMIC/UMIC and HIC (Spearman's ρ LMIC/UMIC 0.824, p < .001; HIC 0.823, p < .001). Among the 74 trials that report country enrollment, 34% (25 of 74) have no authors from LMIC/UMIC. CONCLUSIONS: Among trials that enroll patients in HIC and LMIC/UMIC, authorship appears to be proportional to patient enrollment. This finding is limited by the fact that more than half of RCTs do not report enrollment by country. Moreover, there are important outliers as a significant proportion of RCTs had no authors from LMIC/UMIC despite enrolling patients in these countries. The findings in this study reflect a complex global RCT ecosystem that still underserves cancer control outside high-income settings.

The Impact of an Educational Video in Arabic Language on Patients' Knowledge and Attitudes Towards Genetic Testing for Cancer Therapy.

Rapid advances in cancer genetics are paving the way towards personalized cancer management, and genetic testing is now an important decision-making tool. Despite the advantages, genetic testing adds a layer of complexity in the management which is difficult to communicate with patients. The variability health literacy among patients may restrict their engagement in genetic procedures. Improving the language and presentation of genomic concepts can influence patients' risk assessment and willingness to undergo testing. The study aimed to compare the knowledge and attitudes of cancer patients presenting to oncology clinics at The American University of Beirut Medical Center before and after watching a short educational video that clarifies the concepts of genetic mutations, genetic testing technique, and its purposes.Twenty-nine adult patients presenting to the oncology clinics and due to receive somatic or germline genetic testing filled a questionnaire which assesses their knowledge and attitudes before and after the educational video was played. The majority of patients had poor baseline knowledge before the intervention. After watching the video, the percentage of patients with poor knowledge decreased to a minimum of 3.4% and a maximum of 39% for each concept. Mean score for attitude questions also increased significantly. Effective patient education and counseling programs in the patients' native language prior to genetic testing can increase knowledge, decrease hesitancy, and improve clinical decision making. A short educational video is an example of a simple intervention towards an inclusive approach in patient care all over the world.

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.

The status of bladder cancer research worldwide, a bibliometric review and recommendations.

Background: Healthcare system costs associated with bladder cancer treatment are among the highest of curable malignancies, and prognosis in advanced disease remains poor. This scoping review examines the worldwide status of bladder cancer research by systematically mapping publications, exploring research topics, support, gaps and limitations that need to be addressed. Methods: We searched the Web of Science database for publications using controlled vocabulary. Results were limited between 2000-2020, and were included in our study based on pre-specified eligibility criteria. Data used for analysis included author's names, country of affiliation, language, journal, citations, and funding. Analysis was conducted using Biblioshiny R and SPSS. Research topics were identified according to sub-filters of title words and strings pre-determined by authors. Results: 40,657 results were retrieved, of which 19,976 original articles and reviews met the pre-specified criteria. 92% of the publications originated from 20 countries and were included in the analysis. Trends show an increase across the world, most of which is due to increasing contributions from USA and China. An increase by 1000% in funded publications has been achieved. Studies focused on Surgery, Pathology, and Diagnosis, while Radiotherapy, Palliative care, quality of life and Epidemiology were the least described. Genetics had the most increase while being the most funded. GDP, incidence, prevalence and mortality were each significantly positively correlated with overall bladder cancer research output. Conclusion: This review described the evolution of bladder cancer research. It also identified significant gaps and limitations that need to be highlighted as priority areas for research investment.

Maintenance chemotherapy in advanced and metastatic pancreatic cancer, a narrative review and case series.

Limited data exist on the management of patients with locally advanced (aPC) or metastatic pancreatic (mPC) cancer who achieve stable disease/response after first-line chemotherapy. In this setting, maintenance therapy is important to minimize toxicity while preserving survival benefits. The aim of this study is to conduct a narrative review of the evidence available on the topic and present the results of a retrospective case series of patients with aPC or mPC who received maintenance therapy following a good response to induction chemotherapy. Olaparib is the only drug approved for maintenance therapy in patients with metastatic pancreatic cancer and germline Breast Cancer gene mutation. Data from several trials, including the phase II PANOPTIMOX-PRODIGE35 trial, showed clinical benefit from the use of 5-fluorouracil (5-FU) as maintenance. We also conducted a case series including 12 patients who received FOLFIRINOX as induction chemotherapy for aPC or mPC followed by fluorouracil (5-FU) or FOLFIRI maintenance therapy. Median progression-free survival is 22.13 months which is higher than that reported in the literature, which ranges between 5 and 10.6 months. Although further conclusions cannot be drawn because of the small sample size, the results are promising and encourage further exploration of this topic in larger prospective trials.

Prostate cancer clinical trials in low- and middle-income countries.

Background: Prostate cancer is the second most common form of cancer and a leading cause of cancer-related death in men. In an era of evidence-based medicine, clinical trials play a critical role, and adherence to best practices is crucial in managing complicated and non-communicable diseases, such as prostate cancer. For this reason, extrapolating research conducted in high-income countries (HICs) to low-middle-income countries (LMICs) may lead to incorrect findings or treatment plans for patients in these areas. Unfortunately, clinical trials in LMICs face several challenges in terms of design, funding and recruitment. This study aimed to examine clinical trials on prostate cancer in LMICs, including the scope of these trials, the type of interventions being tested and funding sources. Methods: A search of the Cochrane Library Controlled Trials Registry was conducted between January 2010 and June 2021 using keywords including: 'prostate cancer', 'prostate adenocarcinoma' and 'prostate tumour'). The trials were classified into either HICs or LMICs based on the World Bank Atlas classification. A descriptive analysis was performed to determine the characteristics of the trials. Results: A total of 3,455 clinical trials for prostate cancer have been conducted globally, with 542 (15.68%) conducted LMICs. Most of these trials (89%) were registered in upper-middle-income countries, with none being conducted in low-income countries. The majority of trials were prospective studies (98.1%), with 65.2% being randomised and 57% being phase III. Of the trials, 48.4% aimed to recruit fewer than 500 participants. The main source of funding was pharmaceutical companies in 78.1% of the cases, followed by institutional funds (16.1%) and public funds (5.8%). At the time of the search query, 74.6% of the trials were inactive, with 37% completed, 5% terminated due to insufficient funding and 75% terminated due to medical inefficacy or poor accrual. The majority of trials (88.2%) were interventional, with only 6% focusing on screening and prevention, and 2% designed for palliative care. Conclusion: This study sheds light on the challenges faced in conducting clinical trials for prostate cancer in LMICs. The findings underline the need for improved support from international organisations and pharmaceutical companies to bridge the gaps in prostate cancer research and facilitate collaboration between researchers in LMICs and other countries.

Adjusting the duration of androgen deprivation therapy (ADT) based on nadir PSA for high risk localized prostate cancer patients treated with definitive external beam radiation therapy and ADT.

BACKGROUND: A nadir Prostate-Specific Antigen (nPSA) of 0.06 ng/mL has been shown to be a strong independent predictor of biochemical recurrence-free survival (bRFS) in patients with intermediate or high-risk (HR) prostate cancer treated with definitive external beam radiation therapy (RT) and androgen deprivation therapy (ADT). We aimed to examine the association between the duration of ADT and bRFS in HR localized prostate cancer, based on nPSA. METHODS: Between 1998 and 2015, 204 patients with HR localized prostate cancer were identified. Of them, 157 patients (77.0%) reached the desired nPSA of < 0.06 ng/mL (favorable group), while 47 (23.0%) did not (unfavorable group). Duration of ADT varied among patients depending on physician preference, patient tolerance, and/or compliance. Survival outcomes were calculated using Kaplan-Meier methods and predictors of outcomes using multi-variable cox regression model. RESULTS: In the favorable group, ADT for at least 12 months lead to superior bRFS compared to ≤ 9 months of ADT (P = 0.036). However, no significant difference was seen when examining the value of receiving ADT beyond 12, 18, or 24 months, respectively. On univariate analysis for bRFS, the use of ADT for at least 12 months was significant (P = 0.012) as well as time to nadir PSA (tnPSA), (≤ 6 vs > 6 months); (P = 0.043). The presenting T stage was borderline significant (HR 3.074; 95% CI 0.972-9.719; P = 0.056), while PSA at presentation, Gleason Score and age were not. On multivariate analysis, the use of ADT for 12 months (P = 0.012) and tnPSA (P = 0.037) remained significant. In the unfavorable group, receiving ADT beyond 9 and 12 months was associated with improved bRFS (P = 0.044 and 0.019, respectively). However, beyond 18 months, there was no significant difference. CONCLUSION: In HR localized prostate cancer patients treated with definitive RT and ADT, the total duration of ADT may be adjusted according to treatment response using nPSA. In patients reaching a nPSA below 0.06 ng/mL, a total of 12 months of ADT may be sufficient, while in those not reaching a nPSA below 0.06 ng/mL, a total duration of 18 months is required.

A phase II single arm study of Nivolumab with stereotactic Ablative radiation Therapy after induction chemotherapy in CHOlangiocarcinoma (NATCHO).

BACKGROUND: Intrahepatic cholangiocarcinoma (CCA) is amongst the most common primary liver tumors worldwide. CCA carries a bad prognosis prompting research to establish new treatment modalities other than surgery and the current chemotherapeutic regimens adopted. Hence, this trial explores a new therapeutic approach, to combine stereotactic body radiation therapy (SBRT) and immunotherapy (Nivolumab), and asses its clinical benefit and safety profile after induction chemotherapy in CCA. METHODOLOGY: This is a Phase II open-label, single-arm, multicenter study that investigates Nivolumab (PD-1 inhibitor) treatment at Day 1 followed by SBRT (30 Gy in 3 to 5 fractions) at Day 8, then monthly Nivolumab in 40 patients with non-resectable locally advanced, metastatic or recurrent intrahepatic or extrahepatic CCA. Eligible patients were those above 18 years of age with a pathologically and radiologically confirmed diagnosis of non-resectable locally advanced or metastatic or recurrent intrahepatic or extrahepatic CCA, following 4 cycles of cisplatin-based chemotherapy with an estimated life expectancy of more than 3 months, among other criteria. The primary endpoint is the progression free survival (PFS) rate at 8 months and disease control rate (DCR). The secondary endpoints are overall survival (OS), tumor response rate (TRR), duration of response, evaluation of biomarkers: CD3 + , CD4 + and CD8 + T cell infiltration, as well as any change in the PD-L1 expression through percutaneous core biopsy when compared with the baseline biopsy following 1 cycle of Nivolumab and SBRT. DISCUSSION: SRBT alone showed promising results in the literature by both inducing the immune system locally and having abscopal effects on distant metastases. Moreover, given the prevalence of PD-L1 in solid tumors, targeting it or its receptor has become the mainstay of novel immunotherapeutic drugs use. A combination of both has never been explored in the scope of CCA and that is the aim of this study. TRIAL REGISTRATION: ClinicalTrials.gov NCT04648319 , April 20, 2018.

Cancer registration in the Middle East, North Africa, and Turkey (MENAT) region: A tale of conflict, challenges, and opportunities.

Cancer registration is a core component of national and regional cancer control strategies. In the Middle East, North-Africa and Turkey (MENAT) region, capacity and resources for cancer registration is variable and shaped by multiple contextual challenges. This viewpoint maps out practical recommendations around cancer registration, in an attempt to inform cancer control planning, policy, and implementation. The recommendations laid out in this viewpoint are informed by the discussions held at the Initiative for Cancer Registration in the MENAT (ICRIM) virtual workshop, which convened registry managers, policy makers, and international agencies from 19 countries in the MENAT region. The discussions were distilled in four categories of recommendations, revolving around cancer registration procedures, collaborative governance, putting cancer registration on the map, and capacity building. This viewpoint provides a much-needed mapping of practical recommendations around cancer registration, informed by direct key stakeholders in the region. These practical recommendations offer a road map for policy making, cancer control planning, and future regional capacity strengthening initiatives.
