Katolkar UN, Surana SJ. Exploring the Potential Role of Phytopharmaceuticals in Alleviating Toxicities of Chemotherapeutic Agents. Curr Protein Pept Sci 2024; 25:753-779. [PMID: 38919003 DOI: 10.2174/0113892037307940240606075208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 04/17/2024] [Accepted: 04/24/2024] [Indexed: 06/27/2024]
Abstract
BACKGROUND Chemotherapy is the mainstay of cancer treatment, bringing patients optimism about recurrence and survival. However, the clinical effectiveness of chemotherapeutic drugs is frequently jeopardized by their intrinsic toxicity, resulting in side effects affecting the quality of life of cancer patients. This analysis explores the ethnopharmacological impact of phytopharmaceuticals, highlighting their traditional use in many cultures. The present study, which takes its cues from indigenous knowledge, aims to close the knowledge gap between traditional medicine and modern medicine in reducing the toxicities of chemotherapy treatments. AIM The present in-depth study aims to highlight the current research and upcoming developments in phytopharmaceuticals for reducing the toxicity of chemotherapeutic drugs. Further, we address the mechanisms through which phytopharmaceuticals may reduce chemotherapy-induced side effects that include nausea, vomiting, myelosuppression, nephropathy, neuropathy, and cardiotoxicity using data from a variety of preclinical and clinical investigations. MATERIALS AND METHODS The literature search was carried out by employing search engines such as PubMed and Google Scholar with keywords such as cancer, chemotherapy, CNS toxicity, hematopoietic toxicity, renal toxicity, GI toxicity, CNS toxicity, and phytopharmaceuticals. RESULTS Bioactive chemicals found in plants, such as fruits, vegetables, herbs, and spices, are being studied for their capacity to improve the safety and acceptability of chemotherapy regimens. The current review also dives into the investigation of phytopharmaceuticals as adjuvant medicines in cancer treatment, which is a viable path for addressing the pressing need to lessen chemotherapy-induced toxicities. CONCLUSION The present review revealed that the potential of phytopharmaceuticals in alleviating chemotherapeutic drug toxicities would pave the way for better cancer treatment and patient outcomes, harmonizing with the larger trend towards personalized and holistic approaches to chemotherapy.

Abstract
The first Lancet Oncology Commission on Global Cancer Surgery was published in 2015 and serves as a landmark paper in the field of cancer surgery. The Commission highlighted the burden of cancer and the importance of cancer surgery, while documenting the many inadequacies in the ability to deliver safe, timely, and affordable cancer surgical care. This Commission builds on the first Commission by focusing on solutions and actions to improve access to cancer surgery globally, developed by drawing upon the expertise from cancer surgery leaders across the world. We present solution frameworks in nine domains that can improve access to cancer surgery. These nine domains were refined to identify solutions specific to the six WHO regions. On the basis of these solutions, we developed eight actions to propel essential improvements in the global capacity for cancer surgery. Our initiatives are broad in scope, pragmatic, affordable, and contextually applicable, and aimed at cancer surgeons as well as leaders, administrators, elected officials, and health policy advocates. We envision that the solutions and actions contained within the Commission will address inequities and promote safe, timely, and affordable cancer surgery for every patient, regardless of their socioeconomic status or geographic location.

A Review of the Current State of Global Surgical Oncology and the Role of Surgeons Who Treat Cancer: Our Profession’s Imperative to Act Upon a Worldwide Crisis in Evolution. Ann Surg Oncol 2023; 30:3197-3205. [PMID: 36973564 PMCID: PMC10175401 DOI: 10.1245/s10434-023-13352-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 02/19/2023] [Indexed: 03/29/2023]
Abstract
AbstractWorldwide, the capacity of healthcare systems and physician workforce is woefully inadequate for the surgical treatment of cancer. With major projected increases in the global burden of neoplastic disease, this inadequacy is expected to worsen, and interventions to increase the workforce of surgeons who treat cancer and strengthen the necessary supporting infrastructure, equipment, staffing, financial and information systems are urgently called for to prevent this inadequacy from deepening. These efforts must also occur in the context of broader healthcare systems strengthening and cancer control plans, including prevention, screening, early detection, safe and effective treatment, surveillance, and palliation. The cost of these interventions should be considered a critical investment in healthcare systems strengthening that will contribute to improvement in the public and economic health of nations. Failure to act should be seen as a missed opportunity, at the cost of lives and delayed economic growth and development. Surgeons who treat cancer must engage with a diverse array of stakeholders in efforts to address this critical need and are indispensably positioned to participate in collaborative approaches to influence these efforts through research, advocacy, training, and initiatives for sustainable development and overall systems strengthening.

Abstract
Cancer research is a crucial pillar for countries to deliver more affordable, higher quality, and more equitable cancer care. Patients treated in research-active hospitals have better outcomes than patients who are not treated in these settings. However, cancer in Europe is at a crossroads. Cancer was already a leading cause of premature death before the COVID-19 pandemic, and the disastrous effects of the pandemic on early diagnosis and treatment will probably set back cancer outcomes in Europe by almost a decade. Recognising the pivotal importance of research not just to mitigate the pandemic today, but to build better European cancer services and systems for patients tomorrow, the Lancet Oncology European Groundshot Commission on cancer research brings together a wide range of experts, together with detailed new data on cancer research activity across Europe during the past 12 years. We have deployed this knowledge to help inform Europe's Beating Cancer Plan and the EU Cancer Mission, and to set out an evidence-driven, patient-centred cancer research roadmap for Europe. The high-resolution cancer research data we have generated show current activities, captured through different metrics, including by region, disease burden, research domain, and effect on outcomes. We have also included granular data on research collaboration, gender of researchers, and research funding. The inclusion of granular data has facilitated the identification of areas that are perhaps overemphasised in current cancer research in Europe, while also highlighting domains that are underserved. Our detailed data emphasise the need for more information-driven and data-driven cancer research strategies and planning going forward. A particular focus must be on central and eastern Europe, because our findings emphasise the widening gap in cancer research activity, and capacity and outcomes, compared with the rest of Europe. Citizens and patients, no matter where they are, must benefit from advances in cancer research. This Commission also highlights that the narrow focus on discovery science and biopharmaceutical research in Europe needs to be widened to include such areas as prevention and early diagnosis; treatment modalities such as radiotherapy and surgery; and a larger concentration on developing a research and innovation strategy for the 20 million Europeans living beyond a cancer diagnosis. Our data highlight the important role of comprehensive cancer centres in driving the European cancer research agenda. Crucial to a functioning cancer research strategy and its translation into patient benefit is the need for a greater emphasis on health policy and systems research, including implementation science, so that the innovative technological outputs from cancer research have a clear pathway to delivery. This European cancer research Commission has identified 12 key recommendations within a call to action to reimagine cancer research and its implementation in Europe. We hope this call to action will help to achieve our ambitious 70:35 target: 70% average 10-year survival for all European cancer patients by 2035.

Abstract
Styryllactones, a class of compounds obtained from the genus Goniothalamus (Annonaceae), have demonstrated in vitro antitumor activity. However, the aqueous solubility of these compounds is poor. In this study, we identified the absolute configurations of the previously isolated compounds, which were first isolated in our laboratory, by single-crystal X-ray diffraction analysis using Cu Kα radiation. Subsequently, the antitumor activities of the compounds were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide staining in four tumor cell lines. The induced apoptosis activity of leiocarpin E-7'-Monoacetate was studied by an annexin V fluorescein isothiocyanate/propidium iodide double-staining experiment, and the caspase activity was tested in the SW1116 cell line. The results demonstrated that the antitumor activities of cheliensisin A and goniodiol-7-monoacetate were limited by their poor water solubility. To address this issue, hydroxypropyl-β-cyclodextrin (HP-β-CD) complexes of the compounds were synthesized by the saturated aqueous method. The complexes were then analyzed using a differential scanning calorimeter. The IC50 of cheliensisin A was reduced by 45% and 58% against SW1116 and SMMC-7721 cell lines, respectively. Similarly, the IC50 of goniodiol-7-monoacetate was reduced by 55% and 34% against the two tumor cell lines, respectively. To further evaluate whether the styryllactones and complexes possessed selectivity against cancer cell lines and normal cell lines, toxicity against human normal cell line (HEK293T) was evaluated. The results demonstrated that the HP-β-CD complexes displayed more cytotoxicity than the respective pristine compounds against the HEK293T cell line. However, there existed a therapeutic window when the complexes were applied against cancer cell lines. In summary, the synthesis of several styryllactone compounds complexed with HP-β-CD was reported for the first time. These complexes could significantly enhance the cytotoxic effects of styryllactone compounds.

Abstract
Background As crucial regulators and possible biomarkers for cancer development, miRNAs have attracted intensive attention during the last two decades. Among the known miRNAs, miR-135a has been indicated as a tumor suppressor in several cancer types, whereas its roles and mechanisms in gastric cancer (GC) remain largely unclear. Materials and methods Quantitative PCR (qPCR) was conducted to detect the expression of miR-135a in paired GC tissues as well as cell lines. The prognostic value was evaluated by Kaplan–Meier survival analysis. Wound healing and transwell assays were performed to determine the roles of miR-135a in GC cell migration. Dual-luciferase reporter assay, qPCR, and Western blot analysis were used to validate the targeting of TRAF5 and subsequent NF-κB pathway by miR-135a. Rescue experiments were done to explain the involvement of TRAF5 in mediating the anti-migration effect of miR-135a in GC cells. Finally, the expression of TRAF5 was examined in paired GC tissues. Results miR-135a was confirmed to be decreased in GC tissues and cell lines, and its lower expression predicted worse overall survival. Cellular experiments proved that miR-135a suppressed migration in GC cells. Through directly targeting TRAF5 and subsequently inhibiting NF-κB pathway, miR-135a might efficiently inhibit GC cell metastasis. Furthermore, we found that TRAF5 overexpression was negatively correlated with miR-135a expression in GC tissues. Conclusion Our study indicated that miR-135a serves a suppressing role in GC cell migration by targeting TRAF5 and the downstream NF-κB pathway.

Abstract
AIM To investigate the regulatory effect of the miR-346/DKK3 axis on tumor cell proliferation in colon cancer.
METHODS The expression of miR-346 in normal colon epithelial cells and colon cancer cells as well as in colon tissues and noncancerous tissues was examined by RT-PCR. The effect of miR-346 on the proliferation of colon cancer cells was examined by MTT assay. Flow cytometry was used to detect the effect of miR-346 on the colon cancer cell cycle. The dual luciferase reporter gene assay was used to validate the binding relationship between miR-346 and DKK3. The effect of DKK3 on the function of colon cancer cells was studied by transfecting colon cancer cells with siRNA and pcDNA-DKK3.
RESULTS The expression of miR-346 in colon cancer cells was significantly upregulated. Overexpression of miR-346 promoted the proliferation of colon cancer cells. The proportion of cells in G1 phase decreased, and the proportion of cells in S phase and G2/M phase increased. The dual luciferase reporter assay showed that miR-346 bound directly to the 3'-UTR of DKK3. Inhibition of DKK3 using siRNA promoted the proliferation of colon cancer cells, reduced the proportion of cells in G1 phase and increased the proportion of cells in S phase and G2/M phase. Further, overexpression of DKK3 partially abrogated the proliferative effect of miR-346 on colon cancer cells.
CONCLUSION MiR-346 promotes the proliferation of colon cancer cells by inhibiting DKK3.

Abstract
BACKGROUND Cancer research is among the most active biomedical research domains for the European Union (EU). However, little quantitative empirical evidence is available to guide the decisions on the choice of disease site to study, specific research domain focus or allocation of research resources. To inform national/supranational cancer research policy, high-resolution intelligence is needed. METHODS We performed a bibliometric analysis of European cancer research papers in the Web of Science from 2002 to 2013 to quantify research activity in each of the 28 EU Member States, along with Iceland, Norway and Switzerland (EUR31), which cancer sites/research domains they addressed, and their sources of financial support (2009-2013). FINDINGS Cancer research papers from EUR31 correlated well with national Gross Domestic Products (r2 = 0.94). However, certain cancer sites (lung, oesophagus and pancreas) were under-researched relative to their disease burden, whereas central nervous system and blood cancers were more generously supported than their burden would warrant. An analysis of research domains indicated a paucity of research on radiotherapy (5%), palliative care (1.2%) and quality of life (0.5%). European cancer research funding in 2012-2013 amounted to ∼€7.6 billion and came from diverse sources, especially in western Europe/Scandinavia, where in nine countries the charitable sector outspent the government but not in Eastern Europe where charitable research funding barely exists. INTERPRETATION Several countries need to increase their cancer research outputs substantially, and/or alter their research portfolios to better match their growing (and changing) cancer burden. More co-ordination among funding agencies is required, so that resources can be attuned to align activities to research gaps and perceived clinical needs. In Eastern Europe, the charitable funding sector needs to be developed, so that both public and patient advocacy can have an active role in research.

Abstract
Gastric cancer (GC) is a common malignant tumor of the digestive system. In addition, GC metastasis is an extremely complicated process. In this article, high expression levels of EMS1 mRNA and protein were found to be positively correlated with an enhanced malignant potential of GC cells and a poor clinical prognosis of GC patients. Interestingly, the expression levels of EMS1 mRNA and protein in GC cells were inhibited by microRNA-545 (miR-545), which was identified by a bioinformatics analysis. The expression level of miR-545 in carcinoma tissues was significantly lower than that in para-carcinoma tissues. The proliferation and epithelial-mesenchymal transition (EMT) of GC cells were suppressed by exogenous oligonucleotides of miR-545 mimics. In addition, the expression levels of EMT-associated markers were altered with the expression of miR-545. Notably, the growth rates of tumors in nude mice were seriously restrained by an intratumoral injection of oligonucleotides of the miR-545 mimics. These results suggest a negative regulatory role of miR-545 on the oncogenic activity of EMS1. In addition, EMS1 and miR-545 may be potential biomarkers for GC diagnosis. Synthesized oligonucleotides of miR-545 mimics may be developed as important gene medicines for GC therapy in the future.

Abstract
Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

Abstract
Background Colorectal cancer (CRC) is one of the most common malignances worldwide. Metastasis is responsible for the rapid recurrence and poor prognosis of CRC. However, the underlying molecular mechanism of CRC metastasis remains largely unclear. In this study we purposed to investigate the expression and biological functions of miR-490-3p in CRC metastasis, as well as to identify its downstream target genes and influenced pathway. Methods The expression level of miR-490-3p in CRC cell lines, CRC adjacent normal tissues, non-metastasis and metastasis tissues were assessed by quantitative real-time PCR. Patient survivals were follow-up up to 7 years. Gain-of-function and loss-of-function study on cell migration and invasion abilities were carried out by transfection of miR-490-3p mimics or inhibitors respectively. The molecular targets of miR-490-3p were computationally identified and experimentally verified by dual-luciferase reporter assay and western blot. Functional rescue was also conducted to confirm miR-490-3p inhibits CRC metastasis by targeting TGF-β signaling pathway. Results miR-490-3p expression was persistently downregulated during CRC malignant progression, as well as in CRC cell lines. Artificially overexpression miR-490-3p in CRC cell lines inhibited cell migration and invasion abilities while knockdown miR-490-3p expression caused the reverse effects. TGFβR1 and MMP2/9 were the downstream targets of miR-490-3p in CRC. Inhibition of TGFβR1 could partially recover the tumor suppression effect of miR-490-3p. Conclusion miR-490-3p is downregulated during CRC malignant progression. miR-490-3p represses CRC cell migration and invasion abilities, partially by targeting to the TGF-β signaling pathway. Taken together, miR-490-3p is acting as a tumor suppressor in CRC.

Abstract
PURPOSE Quality cancer care is best delivered through a multidisciplinary approach requiring awareness of current evidence for all oncologic specialties. The highest impact journals often disseminate such information, so the distribution and characteristics of oncology studies by primary intervention (local therapies, systemic therapies, and targeted agents) were evaluated in 10 high-impact journals over a 20-year period. METHODS AND MATERIALS Articles published in 1994, 2004, and 2014 in New England Journal of Medicine, Lancet, Journal of the American Medical Association, Lancet Oncology, Journal of Clinical Oncology, Annals of Oncology, Radiotherapy and Oncology, International Journal of Radiation Oncology, Biology, Physics, Annals of Surgical Oncology, and European Journal of Surgical Oncology were identified. Included studies were prospectively conducted and evaluated a therapeutic intervention. RESULTS A total of 960 studies were included: 240 (25%) investigated local therapies, 551 (57.4%) investigated systemic therapies, and 169 (17.6%) investigated targeted therapies. More local therapy trials (n=185 [77.1%]) evaluated definitive, primary treatment than systemic (n=178 [32.3%]) or targeted therapy trials (n=38 [22.5%]; P<.001). Local therapy trials (n=16 [6.7%]) also had significantly lower rates of industry funding than systemic (n=207 [37.6%]) and targeted therapy trials (n=129 [76.3%]; P<.001). Targeted therapy trials represented 5 (2%), 38 (10.2%), and 126 (38%) of those published in 1994, 2004, and 2014, respectively (P<.001), and industry-funded 48 (18.9%), 122 (32.6%), and 182 (54.8%) trials, respectively (P<.001). Compared to publication of systemic therapy trial articles, articles investigating local therapy (odds ratio: 0.025 [95% confidence interval: 0.012-0.048]; P<.001) were less likely to be found in high-impact general medical journals. CONCLUSIONS Fewer studies evaluating local therapies, such as surgery and radiation, are published in high-impact oncology and medicine literature. Further research and attention are necessary to guide efforts promoting appropriate representation of all oncology studies in high-impact, broad-readership journals.

Abstract
Background We describe trends in participation by investigators from low- and middle-income countries (LMCs) in publications describing oncology randomized control trials (RCTs) over a decade. Methods We used Medline to identify RCTs published in English from 1998 to 2008 evaluating treatment in lung, breast, colorectal, stomach and liver cancers. Data on author affiliations, authorship roles, trial characteristics, funding and interventions were extracted from each article. Countries were stratified as low-, middle- or high-income using World Bank data. Interventions were categorized as requiring basic, limited, enhanced or maximal resources as per the Breast Health Global Initiative classification. Logistic regression was used to identify factors associated with authorship by investigators from LMCs. Results 454 publications were identified. Proportion of articles with at least one LMC author increased over time from 20% in 1998 to 29% in 2008 (p = 0.01), but almost all LMC authors were from middle-income countries. Proportion of articles with at least one LMC author was higher among articles that explicitly reported recruitment in at least one LMC vs those that did not (76% vs 13%). Among 87 articles (19%) that involved authors from LMCs, 17% had LMC authors as first or corresponding authors, and 67% evaluated interventions requiring enhanced or maximal resources. Factors associated with LMC authorship included industry funding (OR = 3.54, p = 0.0001), placebo comparator arm (OR = 2.57, p = 0.02) and palliative intent treatment (OR = 4.00, p = 0.0003). Conclusion An increasing number of publications describing oncology RCTs involve authors from LMC countries but primarily in non-leadership roles in industry-funded trials.

Abstract
BACKGROUND It is unknown whether changes in study sponsorship have affected the proportion of prospective research on surgery, radiotherapy, and pharmacotherapy for head and neck squamous cell carcinoma (HNSCC) being published over time. PATIENTS AND METHODS We examined prospective studies from PubMed, Ovid MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from 1980, 1985, 1990, 1995, 2000, 2005, and 2010. Chi-squared tests were used to identify significant associations between sponsorship and authorship, treatments within study protocols, and presentation of results, whereas time-based trends were analyzed using the Cochran-Armitage test. RESULTS Among 309 articles, industry (70, 22.7%) and the U.S. government (65, 21%) were the most common sponsors. There was a significant increase in the proportion of industry-sponsored research (p for trend = .013) and a decline in U.S. government-sponsored research (p for trend = .001) over time. The inclusion of surgery in treatment protocols declined over the past four decades (p for trend = .003). Protocols incorporating pharmacotherapy were more likely to have industry support than those without pharmacotherapy (p = .001), whereas protocols with radiotherapy (p = .003) or surgery (p = .002) were less likely to have industry support. CONCLUSION Industry is the predominant sponsor of prospective HNSCC research, with an emphasis on pharmacotherapy.

Abstract
Casticin, a polymethoxyflavone, has been reported to exert anticancer activities. The objectives of this study were to examine the molecular mechanisms by which casticin induces the growth inhibition and cell cycle arrest in human hepatocellular carcinoma (HCC) cells. The HCC cell lines Hep G2 and PLC/PRF/5 were cultured in vitro. The growth inhibitory effects of casticin were evaluated using clonogenic assays. The distribution of phases in the cell cycle was analyzed using flow cytometry (FCM) analysis with propidium iodide (PI) staining. Multiple molecular techniques, such as western blotting and gene transfection, were used to explore the molecular mechanisms of action. Our data demonstrated that casticin significantly inhibited cell viability and colony formation in HCC cells. Furthermore, it induced cell cycle arrest in the G2/M phase. Casticin inhibited phosphorylation of the FOXO3a protein and decreased the expression of FoxM1 and its downstream genes, such as cyclin-dependent kinase (CDK1), cdc25B and cyclin B and increased the expression of p27KIP1. Silencing of FOXO3a expression by small interfering RNA (siRNA) transfection clearly attenuated the inhibitory effects of casticin on FOXM1 expression and cell growth. Our findings provided clear evidence that casticin induces growth suppression and cell cycle arrest through inhibition of FOXO3a phosphorylation causing inactivation of FOXM1 in HCC cells.
