RESUMO

BACKGROUND: Mannitol is exclusively recommended in the National Comprehensive Cancer Network guidelines for diuresis in cisplatin (CDDP)-based chemotherapy. The utility of furosemide, a widely used and convenient diuretic, thus requires clarification. METHODS: This is a prospective, single-centered, open-label, noninferiority phase II study. Patients with thoracic malignancies who planned to receive CDDP-based chemotherapy were randomly assigned to receive either mannitol (arm A) or furosemide (arm B). The primary end point was set as the proportion of patients who experienced any grade of "creatinine (Cr) increased" based on the upper limit of the normal range (ULN) during the first cycle as assessed by Common Terminology Criteria for Adverse Events Version 4.0. Secondary end points were Cr increased based on the baseline value during the first cycle, Cr increased after the completion of CDDP, and the proportion of patients with phlebitis. RESULTS: Between April 2018 and March 2022, 115 patients were enrolled and 106 were analyzed. Any grade of Cr increased based on the ULN during the first cycle was 17.3% (arm A) and 24.1% (arm B), respectively (p = 0.34). Therefore, the primary end point was not met. After completion of chemotherapy, any grade of Cr increased was observed in 23.1% (arm A) and 31.5% (arm B), respectively. However, the actual serum Cr level and Cr clearance during the courses were not different between the arms. Phlebitis occurred more frequently in arm A (28.8%) than arm B (16.7%). CONCLUSIONS: Mannitol should remain the standard diuresis in CDDP-based chemotherapy assessed by conventional CTCAE grading, but furosemide can be room for consideration when assessed by actual serum Cr level and Cr clearance.

RESUMO

BACKGROUND: Real-world data (RWD) related to the health status and care of cancer patients reflect the ongoing medical practice, and their analysis yields essential real-world evidence. Advanced information technologies are vital for their collection, qualification, and reuse in research projects. METHODS: UNICANCER, the French federation of comprehensive cancer centres, has innovated a unique research network: Consore. This potent federated tool enables the analysis of data from millions of cancer patients across eleven French hospitals. RESULTS: Currently operational within eleven French cancer centres, Consore employs natural language processing to structure the therapeutic management data of approximately 1.3 million cancer patients. These data originate from their electronic medical records, encompassing about 65 million medical records. Thanks to the structured data, which are harmonized within a common data model, and its federated search tool, Consore can create patient cohorts based on patient or tumor characteristics, and treatment modalities. This ability to derive larger cohorts is particularly attractive when studying rare cancers. CONCLUSIONS: Consore serves as a tremendous data mining instrument that propels French cancer centres into the big data era. With its federated technical architecture and unique shared data model, Consore facilitates compliance with regulations and acceleration of cancer research projects.

RESUMO

Analyses of inequalities related to prevention and cancer therapeutics/care show disparities between countries with different economic standing, and within countries with high Gross Domestic Product. The development of basic technological and biological research provides clinical and prevention opportunities that make their implementation into healthcare systems more complex, mainly due to the growth of Personalized/Precision Cancer Medicine (PCM). Initiatives like the USA-Cancer Moonshot and the EU-Mission on Cancer and Europe's Beating Cancer Plan are initiated to boost cancer prevention and therapeutics/care innovation and to mitigate present inequalities. The conference organized by the Pontifical Academy of Sciences in collaboration with the European Academy of Cancer Sciences discussed the inequality problem, dependent on the economic status of a country, the increasing demands for infrastructure supportive of innovative research and its implementation in healthcare and prevention programs. Establishing translational research defined as a coherent cancer research continuum is still a challenge. Research has to cover the entire continuum from basic to outcomes research for clinical and prevention modalities. Comprehensive Cancer Centres (CCCs) are of critical importance for integrating research innovations to preclinical and clinical research, as for ensuring state-of-the-art patient care within healthcare systems. International collaborative networks between CCCs are necessary to reach the critical mass of infrastructures and patients for PCM research, and for introducing prevention modalities and new treatments effectively. Outcomes and health economics research are required to assess the cost-effectiveness of new interventions, currently a missing element in the research portfolio. Data sharing and critical mass are essential for innovative research to develop PCM. Despite advances in cancer research, cancer incidence and prevalence is growing. Making cancer research infrastructures accessible for all patients, considering the increasing inequalities, requires science policy actions incentivizing research aimed at prevention and cancer therapeutics/care with an increased focus on patients' needs and cost-effective healthcare.

RESUMO

Breast cancer stands as the most prevalent and heterogeneous malignancy affecting women globally, posing a substantial health concern. Enhanced comprehension of tumor pathology and the development of novel therapeutics are pivotal for advancing breast cancer treatment. Contemporary breast cancer investigation heavily leans on in vivo models and conventional cell culture techniques. Nonetheless, these approaches often encounter high failure rates in clinical trials due to species disparities and tissue structure variations. To address this, three-dimensional cultivation of organoids, resembling organ-like structures, has emerged as a promising alternative. Organoids represent innovative in vitro models that mirror in vivo tissue microenvironments. They retain the original tumor's diversity and facilitate the expansion of tumor samples from diverse origins, facilitating the representation of varying tumor stages. Optimized breast cancer organoid models, under precise culture conditions, offer benefits including convenient sample acquisition, abbreviated cultivation durations, and genetic stability. These attributes ensure a faithful replication of in vivo traits of breast cancer cells. As intricate cellular entities boasting spatial arrangements, breast cancer organoid models harbor substantial potential in precision medicine, organ transplantation, modeling intricate diseases, gene therapy, and drug innovation. This review delivers an overview of organoid culture techniques and outlines future prospects for organoid modeling.

RESUMO

The drug development process involves a variety of drug activity evaluations, which can determine drug efficacy, strictly analyze the biological indicators after the drug action, and use these indicators as the preclinical drug evaluation criteria. At present, most of the screening of preclinical anticancer drugs mainly relies on traditional 2D cell culture. However, this traditional technology cannot simulate the tumor microenvironment in vivo, let alone reflect the characteristics of solid tumors in vivo, and has a relatively poor ability to predict drug activity. 3D cell culture is a technology between 2D cell culture and animal experiments, which can better reflect the biological state in vivo and reduce the consumption of animal experiments. 3D cell culture can link the individual study of cells with the study of the whole organism, reproduce in vitro the biological phenotype of cells in vivo more greatly, and thus predict the activity and resistance of anti-tumor drugs more accurately. In this paper, the common techniques of 3D cell culture are discussed, with emphasis on its main advantages and application in the evaluation of anti-tumor resistance, which can provide strategies for the screening of anti-tumor drugs.

RESUMO

PURPOSE: To assess the effectiveness and safety of acupuncture for the prevention of chemotherapy-induced nausea and vomiting (CINV), with a specific intention on exploring sources of between-study variation in treatment effects. METHODS: MEDLINE, EMBASE, Cochrane CENTRAL, CINAHL, Chinese Biomedical Literature Database, VIP Chinese Science and Technology Periodicals Database, China National Knowledge Infrastructure, and Wanfang were searched to identify randomized controlled trials (RCTs) that compared acupuncture to sham acupuncture or usual care (UC). The main outcome is complete control (no vomiting episodes and/or no more than mild nausea) of CINV. GRADE approach was used to rate the certainty of evidence. RESULTS: Thirty-eight RCTs with a total of 2503 patients were evaluated. Acupuncture in addition to UC may increase the complete control of acute vomiting (RR, 1.13; 95% CI, 1.02 to 1.25; 10 studies) and delayed vomiting (RR, 1.47; 95% CI, 1.07 to 2.00; 10 studies) when compared with UC only. No effects were found for all other review outcomes. The certainty of evidence was generally low or very low. None of the predefined moderators changed the overall findings, but in an exploratory moderator analysis we found that an adequate reporting of planned rescue antiemetics might decrease the effect size of complete control of acute vomiting (p = 0.035). CONCLUSION: Acupuncture in addition to usual care may increase the complete control of chemotherapy-induced acute vomiting and delayed vomiting but the certainty of evidence was very low. Well-designed RCTs with larger sample sizes, standardized treatment regimens, and core outcome measures are needed.

RESUMO

To meet the rising demand for flexible learning in data-driven health research, we adapted an in-person undergraduate research program (Quantitative Sciences Undergraduate Research Experience (QSURE)) to an all-virtual framework in summer 2020 and 2021. We used Web-conferencing and remote computing to implement virtual hands-on research training within a comprehensive cancer center. We designed the program to achieve research and career development goals: students completed faculty-mentored quantitative research projects and received education in the responsible conduct of research and practical skills, such as oral and written presentation. We assessed virtual program efficacy using pre- and post-program quantitative and qualitative student feedback. Eighteen students participated (nine each year); they reported high satisfaction with the virtual format. Compared with baseline, students reported improved perceived competence in quantitative skills and research knowledge post-program; these improvements were comparable to the in-person program. Defined benchmarks and consistent communication (with mentors, program directors, other students) were crucial to students' success; however, students noted challenges in building camaraderie online. With adequate resources, Web-based technology can be leveraged as an effective format for hands-on quantitative research training. Our framework can be tailored to an institution's needs, particularly those for which available resources better align with a virtual research program.

RESUMO

The National Cancer Institute's Youth Enjoy Science Research Education Program (YES) supports cancer-based research experiences, curriculum development and outreach activities to foster diversity in the biomedical workforce. The University of Chicago Medicine Comprehensive Cancer Center was among the first recipients of the YES award in 2017, launching the Chicago EYES (Educators and Youth Enjoy Science) on Cancer program for high school and college students. The EYES team also introduced immersive research experiences and mentored curriculum development for high school science teachers, a potentially powerful means to extend science enrichment and career exposure to schools across Chicago. Ongoing evaluation of the EYES program suggests positive outcomes in terms of trainees' research skill development and their knowledge about, and positive attitudes towards, careers in biomedicine. Teacher research fellows reported that the program inspired new insights about science learning and practice that not only strengthened their skills as science educators, but also improved their ability to relate to their pupils. These findings contribute to the broader effort to establish best practices among cancer research training programs, particularly those with a shared mission to empower youth from diverse backgrounds to contribute to a field deeply in need of their talents and perspectives.

RESUMO

Silver has been in clinical use since ancient times and silver nanoparticles (AgNPs) have attracted attention in cancer therapy. We investigated the mechanisms by which AgNPs inhibit pancreatic ductal adenocarcinoma (PDAC). AgNPs were synthesized and 3 human PDAC and 2 nonmalignant primary cell lines were treated with AgNPs. MTT, MAPK, colony, spheroid and scratch assays, Western blotting, TEM, annexin V, 7-AAD, and H2DCFDA staining, FACS analysis, mRNA array and bioinformatics analyses, tumor xenograft transplantation, and immunohistochemistry of the treated cells were performed. We found that minimal AgNPs amounts selectively eradicated PDAC cells within a few hours. AgNPs inhibited cell migration and spheroid and colony formation, damaged mitochondria, and induced paraptosis-like cell death with the presence of cytoplasmic vacuoles, dilation of the ER and mitochondria, ROS formation, MAPK activity, and p62 and LC3b expression, whereas effects on the nucleus, DNA fragmentation, or caspases were not detectable. AgNPs strongly decreased tumor xenograft growth without side effects and reduced the expression of markers for proliferation and DNA repair, but upregulated paraptosis markers. The results highlight nanosilver as complementary agent to improve the therapeutic efficacy in pancreatic cancer.

RESUMO

BACKGROUND: The 2020 National Comprehensive Cancer Network guidelines recommend neoadjuvant FOLFIRINOX or neoadjuvant gemcitabine plus nab-paclitaxel (G-nP) for borderline resectable/locally advanced pancreatic ductal adenocarcinoma (BR/LA PDAC). AIM: The purpose of our study was to compare treatment outcomes, toxicity profiles, costs, and quality-of-life measures between these two treatments to further inform clinical decision-making. METHODS AND RESULTS: We developed a decision-analytic mathematical model to compare the total cost and health outcomes of neoadjuvant FOLFIRINOX against G-nP over 12 years. The model inputs were estimated using clinical trial data and published literature. The primary endpoint was incremental cost-effectiveness ratios (ICERs) with a willingness-to-pay threshold of $100 000 per quality-adjusted-life-year (QALY). Secondary endpoints included overall (OS) and progression-free survival (PFS), total cost of care, QALYs, PDAC resection rate, and monthly treatment-related adverse events (TRAE) costs (USD). FOLFIRINOX was the cost-effective strategy, with an ICER of $60856.47 per QALY when compared to G-nP. G-nP had an ICER of $44639.71 per QALY when compared to natural history. For clinical outcomes, more patients underwent an "R0" resection with FOLFIRINOX compared to G-nP (84.9 vs. 81.0%), but FOLFIRINOX had higher TRAE costs than G-nP ($10905.19 vs. $4894.11). A one-way sensitivity analysis found that the ICER of FOLFIRINOX exceeded the threshold when TRAE costs were higher or PDAC recurrence rates were lower. CONCLUSION: Our modeling analysis suggests that FOLFIRNOX is the cost-effective treatment compared to G-nP for BR/LA PDAC despite having a higher cost of total care due to TRAE costs. Trial data with sufficient follow-up are needed to confirm our findings.

RESUMO

Introduction Breast cancer is the most common cancer among women worldwide and one of the main causes of death in the female sex. Genetic polymorphisms in the mu-opioid receptor (OPRM1) and catechol-o-methyltransferase (COMT) genes have been shown to increase breast cancer risk. Variants in these genes may carry a prognostic impact in breast cancer. Long follow-up intervals are critical to adequately analyze prognosis in diseases with prolonged survival times and late relapses. Objective To analyze the impact of genetic polymorphisms on the survival of a cohort of breast cancer patients with very long follow-up. Methods This was a retrospective study of patients treated at Portuguese Oncology Institute of Porto (IPO Porto), a Portuguese comprehensive cancer center, with invasive carcinoma of the breast with very long follow-up, with analysis of genetic polymorphisms OPMR1 rs1799971 (AA vs. G allele) and COMT rs4680 (CC vs T allele) on biological samples. Statistical analysis of survival was performed using the Kaplan-Meier method, log-rank test, and Cox regression method. Results A total of 143 patients with invasive breast cancer were included, with a median follow-up of 21.5 years. There was a statistically significant difference in overall survival (OS) at 30 years according to the OPMR1 polymorphism, with lower survival in patients with the AA genotype (p<0.05). The difference in OS according to the COMT polymorphism was also statistically significant, with worse survival in patients with genotype T allele (p<0.05). The genetic variants were not associated with patient age, stage at diagnosis, or tumor grade. Discussion The genetic polymorphisms of OPRM1 and COMT affected the overall survival of breast cancer patients, in concordance with previous research. Further investigation is needed in order to clarify the prognostic impact of these genetic alterations on breast cancer.

RESUMO

Key stakeholders from the cancer research continuum met in May 2021 at the European Cancer Research Summit in Porto to discuss priorities and specific action points required for the successful implementation of the European Cancer Mission and Europe's Beating Cancer Plan (EBCP). Speakers presented a unified view about the need to establish high-quality, networked infrastructures to decrease cancer incidence, increase the cure rate, improve patient's survival and quality of life, and deal with research and care inequalities across the European Union (EU). These infrastructures, featuring Comprehensive Cancer Centres (CCCs) as key components, will integrate care, prevention and research across the entire cancer continuum to support the development of personalized/precision cancer medicine in Europe. The three pillars of the recommended European infrastructures - namely translational research, clinical/prevention trials and outcomes research - were pondered at length. Speakers addressing the future needs of translational research focused on the prospects of multiomics assisted preclinical research, progress in Molecular and Digital Pathology, immunotherapy, liquid biopsy and science data. The clinical/prevention trial session presented the requirements for next-generation, multicentric trials entailing unified strategies for patient stratification, imaging, and biospecimen acquisition and storage. The third session highlighted the need for establishing outcomes research infrastructures to cover primary prevention, early detection, clinical effectiveness of innovations, health-related quality-of-life assessment, survivorship research and health economics. An important outcome of the Summit was the presentation of the Porto Declaration, which called for a collective and committed action throughout Europe to develop the cancer research infrastructures indispensable for fostering innovation and decreasing inequalities within and between member states. Moreover, the Summit guidelines will assist decision making in the context of a unique EU-wide cancer initiative that, if expertly implemented, will decrease the cancer death toll and improve the quality of life of those confronted with cancer, and this is carried out at an affordable cost.

RESUMO

The fight against cancer is one of the main challenges for medical research. Recently, nanotechnology has made significant progress, providing possibilities for developing innovative nanomaterials to overcome the common limitations of current therapies. In this context, silver nanoparticles (AgNPs) represent a promising nano-tool able to offer interesting applications for cancer research. Following this path, we combined the silver proprieties with Artemisia arborescens characteristics, producing novel nanoparticles called Artemisia-AgNPs. A "green" synthesis method was performed to produce Artemisia-AgNPs, using Artemisia arborescens extracts. This kind of photosynthesis is an eco-friendly, inexpensive, and fast approach. Moreover, the bioorganic molecules of plant extracts improved the biocompatibility and efficacy of Artemisia-AgNPs. The Artemisia-AgNPs were fully characterized and tested to compare their effects on various cancer cell lines, in particular HeLa and MCF-7. Artemisia-AgNPs treatment showed dose-dependent growth inhibition of cancer cells. Moreover, we evaluated their impact on the cell cycle, observing a G1 arrest mediated by Artemisia-AgNPs treatment. Using a clonogenic assay after treatment, we observed a complete lack of cell colonies, which demonstrated cell reproducibility death. To have a broader overview on gene expression impact, we performed RNA-sequencing, which demonstrated the potential of Artemisia-AgNPs as a suitable candidate tool in cancer research.

RESUMO

BACKGROUND: Yoga is a meditative movement therapy focused on mind-body awareness. The impact of yoga on health-related quality of life (HRQOL) outcomes in patients with chemotherapy-induced peripheral neuropathy (CIPN) is unclear. METHODS: We conducted a pilot randomized wait-list controlled trial of 8 weeks of yoga (n = 21) versus wait-list control (n = 20) for CIPN in 41 breast and gynecological cancer survivors with persistent moderate to severe CIPN. HRQOL endpoints were Hospital Anxiety and Depression Scale (HADS), Brief Fatigue Inventory (BFI), and Insomnia Severity Index (ISI). The Treatment Expectancy Scale (TES) was administered at baseline. We estimated mean changes and 95% confidence intervals (CIs) from baseline to weeks 8 and 12 and compared arms using constrained linear mixed models. RESULTS: At week 8, HADS anxiety scores decreased -1.61 (-2.75, -0.46) in the yoga arm and -0.32 (-1.38, 0.75) points in the wait-list control arm (p = 0.099). At week 12, HADS anxiety scores decreased -1.42 (-2.57, -0.28) in yoga compared to an increase of 0.46 (-0.60, 1.53) in wait-list control (p = 0.017). There were no significant differences in HADS depression, BFI, or ISI scores between yoga and wait-list control. Baseline TES was significantly higher in yoga than in wait-list control (14.9 vs. 12.7, p = 0.019). TES was not associated with HADS anxiety reduction and HADS anxiety reduction was not associated with CIPN pain reduction. CONCLUSIONS: Yoga may reduce anxiety in patients with CIPN. Future studies are needed to confirm these findings. CLINICAL TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier: NCT03292328.

RESUMO

Since spring 2020, the COVID-19 pandemic has disrupted development of the next generation of cancer researchers and physicians, forcing pathway programs across the nation to cancel, postpone or reinvent education and training activities. Accordingly, the University of Chicago's Chicago EYES on Cancer program was converted to a fully-online format, which prioritized flexibility for the 26 high school and undergraduate trainees, from underrepresented backgrounds, who were eligible to participate. Evaluation data suggest that the program's redesign successfully preserved trainees' access to intellectual, social and financial support despite the pandemic, with 88% of trainees meeting, and most exceeding, program requirements. Data also suggest positive outcomes for trainees, particularly with regard to their understanding of careers in biomedicine, their commitment to and confidence in planning for a research career, and their readiness and self-confidence as researchers. In the immediate term, our experiences offer practical insights for our colleagues similarly challenged to provide high-quality cancer research training within the context of COVID. In the long term, the success of our online programming can be leveraged to extend enrichment opportunities to program alumni, partner schools and other priority groups as a permanent component of the Comprehensive Cancer Center's broad cancer education strategy.

RESUMO

Metabolic reprogramming of tumour cells sustains cancer progression. Similar to other cancer cells, glioblastoma cells exhibit an increased glycolytic flow, which encourages the use of antiglycolytics as an effective complementary therapy. We used the antiglycolytic 3-bromopyruvate (3BP) as a metabolic modifier to treat U118 glioblastoma cells and investigated the toxic effects and the conditions to increase drug effectiveness at the lowest concentration. Cellular vitality was not affected by 3BP concentrations lower than 40 µM, although p-Akt dephosphorylation, p53 degradation, and ATP reduction occurred already at 30 µM 3BP. ROS generated in mitochondria were enhanced at 30 µM 3BP, possibly by unbalancing their generation and their disposal because of glutathione peroxidase inhibition. ROS triggered JNK and ERK phosphorylation, and cyt c release outside mitochondria, not accompanied by caspases-9 and -3 activation, probably due to 3BP-dependent alkylation of cysteine residues at caspase-9 catalytic site. To explore the possibility of sensitizing cells to 3BP treatment, we exploited 3BP effects on mitochondria by using 30 µM 3BP in association with antimycin A or menadione concentrations that in themselves exhibit poor toxicity. 3BP effect on cyt c release and cell vitality loss was potentiated due the greater oxidative stress induced by antimycin or menadione association with 3BP, supporting a preeminent role of mitochondrial ROS in 3BP toxicity. Indeed, the scavenger of mitochondrial superoxide MitoTEMPO counteracted 3BP-induced cyt c release and weakened the potentiating effect of 3BP/antimycin association. In conclusion, the biochemical mechanisms leading U118 glioblastoma cells to viability loss following 3BP treatment rely on mitochondrial ROS-dependent pathways. Their potentiation at low 3BP concentrations is consistent with the goal to minimize the toxic effect of the drug towards non-cancer cells.

RESUMO

The efficiency of cancer chemotherapy is seriously hampered by the development of resistance of neoplastic cells to cytotoxic agents. In the present investigation, the cytotoxicity of the dichloromethane-methanol (1:1) extract of Acacia sieberiana (ASL), fractions (ASLa-c) from the leaves and isolated compounds: chrysoeriol-7-O-rutinoside (1), luteolin-7-O-rutinoside (2), chrysoeriol-7-O-ß-D-glucopyranoside (3), Apigenin-7-O-ß-D-glucopyranoside (4), luteolin-3',4'-dimethoxylether-7-O-ß-D-glucoside (5) and luteolin (6) was investigated. The study was extended to the assessment of the mode of induction of apoptosis by ASL. The resazurin reduction assay (RRA) was used for cytotoxicity studies. Assessments of cell cycle distribution, apoptosis, and reactive oxygen species (ROS) were performed by flow cytometry. A caspase-Glo assay was used to evaluate caspase activities. Botanicals ASL, ASLb and ASLc as well as doxorubicin displayed observable IC50 values towards the nine tested cancer cell lines while ASLa and compounds 1-7 had selective activities. The IC50 values ranged from 13.45 µg/mL (in CCRF-CEM leukemia cells) to 33.20 µg/mL (against MDA-MB-231-BCRP breast adenocarcinoma cells) for ASL, from 16.42 µg/mL (in CCRF-CEM cells) to 29.64 µg/mL (against MDA-MB-231-pcDNA cells) for ASLc, and from 22.94 µg/mL (in MDA-MB-231-BCRP cells) to 40.19 µg/mL (against HCT116 (p53-/-) colon adenocarcinoma cells) for ASLb (Table 1), and from 0.02 µM (against CCRF-CEM cells) to 122.96 µM (against CEM/ADR5000 cells) for doxorubicin. ASL induced apoptosis in CCRF-CEM cells, mediated by ROS production. Acacia sieberiana is a good cytotoxic plant and should be further explored to develop an anticancer phytomedicine to combat both sensitive and drug resistant phenotypes.

RESUMO

This study was designed to explore and record various medicinal plants integrated into the traditional system of medicine for the treatment of cancer. The traditional system of medicine is a routine practiced among the indigenous ethnic groups of Sokoto state. A semi-structured questionnaire was designed and used for data collection around the selected Local Government Areas. A substantial number of plant species were identified, recorded, and collected for preservation. Data collected for each specie was analysed to assess its frequent use among the medicinal plants. A total of 67 species belonging to 31 families have been identified and recorded. Out of the 473 frequency of citation (FC), Acacia nilotica was the most frequently cited specie (32 FC, 64% FC, 0.6 RFC), followed by Guiera senegalensis (27 FC, 54% FC, 0.5 RFC), Erythrina sigmoidea (17 FC, 34% FC, 0.3 RFC), and subsequently Combretum camporum (15 FC, 30% FC, 0.3 RFC). The most common parts of the plants used include the barks (55.2%), the roots (53.2%), and the leaves (41.8%). Additionally, decoction (74.6%), powdered form (49.3%), and maceration (46.3%) are the most frequently used mode of preparation. The historical knowledge of a traditional system of medicine practiced by the native traditional healers of Sokoto for the treatment of cancer has been documented. The present study further provides a baseline for future pharmacological investigations into the beneficial effects of such medicinal plants for the treatment of cancer.

RESUMO

Globally, cancer is likely to be ranked as the leading cause of death among non-communicable diseases in the 21st century. In Ghana, estimates suggest that the disease is expected to increase continuously. The best way to address the increasing burden is through a comprehensive cancer control program. This paper presents an appraisal of the literature, reports and, studies that seek to highlight strategies for cancer control globally and in Ghana. In consideration of literature, a search of relevant databases (PubMed, Google Scholar, Cochrane Database of Systematic Reviews, Google, International organizations web pages, International reports, Ministry of Health of Ghana reports, and textbooks) was performed. A narrative review of the background information on this subject is provided to inform future research on cancer control. This review was conducted as part of a study to involve community pharmacists in cancer detection and prevention in Ghana.

RESUMO

A comprehensive translational cancer research approach focused on personalized and precision medicine, and covering the entire cancer research-care-prevention continuum has the potential to achieve in 2030 a 10-year cancer-specific survival for 75% of patients diagnosed in European Union (EU) member states with a well-developed healthcare system. Concerted actions across this continuum that spans from basic and preclinical research through clinical and prevention research to outcomes research, along with the establishment of interconnected high-quality infrastructures for translational research, clinical and prevention trials and outcomes research, will ensure that science-driven and social innovations benefit patients and individuals at risk across the EU. European infrastructures involving comprehensive cancer centres (CCCs) and CCC-like entities will provide researchers with access to the required critical mass of patients, biological materials and technological resources and can bridge research with healthcare systems. Here, we prioritize research areas to ensure a balanced research portfolio and provide recommendations for achieving key targets. Meeting these targets will require harmonization of EU and national priorities and policies, improved research coordination at the national, regional and EU level and increasingly efficient and flexible funding mechanisms. Long-term support by the EU and commitment of Member States to specialized schemes are also needed for the establishment and sustainability of trans-border infrastructures and networks. In addition to effectively engaging policymakers, all relevant stakeholders within the entire continuum should consensually inform policy through evidence-based advice.
