To analyze the overall trends in cancer incidence and mortality in Saudi Arabia between 1990 and 2016. Methods: Data were retrieved through a Global Burden of Disease (GBD, 2016) database (Viz Hub) ...that is developed by the Institute for Health Metrics and Evaluation at the University of Washington. Results: The incidence of cancer increased around 26-fold for thyroid cancer; approximately 10-fold in breast, colon, bladder and uterine cancers; 8-fold for prostate cancer; 5-fold for renal cancer; 4-fold for pancreatic and ovarian cancer; 3.5-fold for lung cancer; 3-fold for liver cancer, and 2 folds for lymphoma, leukemia and gastric cancer. There was also an increase in the percentage of mortality due to cancer during this period. However, we noticed that the percentage of deaths due to cancer decreased after 70 years of age in Saudi Arabia population. Conclusion: The increases in the incidence of different types of cancer in the past decade could be due to the revolutionary change in socioeconomic status that has occurred in Saudi Arabia; therefore, a national plan should be established for cancer prevention, screening and therapy. Concerning mortality, the decrease in its percentage among elderly people could be due to biological factors that should be investigated in the future.
The medicinal plant Scutellaria baicalensis, commonly known as Chinese skullcap or Huang‐Qin, has been used as a traditional medicine for several thousand years. The roots of this plant contain ...bioactive compounds, such as wogonin (WOG), wogonoside, baicalein, and baicalin. The aim of this article is to evaluate the therapeutic potential and mechanisms of action of WOG against different cancers. Numerous in vitro and in vivo studies have revealed that WOG exerts immense therapeutic potential against bladder cancer, breast cancer, cholangiocarcinoma, cervical cancer, colorectal cancer, gallbladder cancer, gastric cancer, glioblastoma, head and neck cancer, hepatic cancer, leukemia, lung cancer, lymphoma, melanoma, multiple myeloma, neuroblastoma, osteosarcoma, ovarian cancer, pancreatic cancer, prostate cancer, and renal cancer by regulating various cell signaling pathways. WOG, in combination with established chemotherapeutic drugs, improves the efficacy of treatment and lowers toxicity. Nevertheless, human trials are warranted to validate these findings. Numerous preclinical studies, combined with an extensive margin of safety and no severe side effects, underscore WOG's therapeutic potential as an anticancer drug. These studies propound the use of WOG as a potential anticancer candidate; however, further high‐quality studies are required to firmly establish the clinical efficacy of WOG for the prevention and treatment of human malignancies.

Nearly half of all Americans will be diagnosed with an invasive cancer—an all-too ordinary aspect of daily life. Through a powerful combination of cultural analysis and memoir, this stunningly ...original book explores why cancer remains so confounding, despite the billions of dollars spent in the search for a cure. Amidst furious debates over its causes and treatments, scientists generate reams of data—information that ultimately obscures as much as it clarifies. Award-winning anthropologist S. Lochlann Jain deftly unscrambles the high stakes of the resulting confusion. Expertly reading across a range of material that includes history, oncology, law, economics, and literature, Jain explains how a national culture that simultaneously aims to deny, profit from, and cure cancer entraps us in a state of paradox—one that makes the world of cancer virtually impossible to navigate for doctors, patients, caretakers, and policy makers alike. This chronicle, burning with urgency and substance leavened with brio and wit, offers a lucid guide to understanding and navigating the quicksand of uncertainty at the heart of cancer. Malignant vitally shifts the terms of an epic battle we have been losing for decades: the war on cancer.
Background
Gastrointestinal (GI) cancers were responsible for 26.3% of cancer cases and 35.4% of deaths worldwide in 2018. This study aimed to analyze the global incidence, mortality, prevalence, and ...contributing risk factors of the 6 major GI cancer entities esophageal cancer (EC), gastric cancer (GC), liver cancer (LC), pancreatic cancer (PC), colon cancer, and rectal cancer.
Methods
Using the Global Cancer Observatory and the Global Health Observatory databases, we reviewed the current GI cancer incidence, prevalence, and mortality, analyzed the association of GI cancer prevalence with national human development indices (HDIs), identified the contributing risk factors, and estimated developing age‐ and sex‐specific trends in incidence and mortality.
Results
In 2020, the trend in age‐standardized rate of incidence of GI cancers closely mirrored that of mortality, with the highest rates of LC, EC, and GC in Asia and of colorectal cancer (CRC) and PC mainly in Europe. Incidence and mortality were positively, but the mortality‐to‐incidence ratio (MIR) was inversely correlated with the national HDI levels. High MIRs in developing countries likely reflected the lack of preventive strategies and effective treatments. GI cancer prevalence was highest in Europe and was also positively correlated with HDIs and lifestyle‐associated risk factors, such as alcohol consumption, smoking, obesity, insufficient physical activity, and high blood cholesterol level, but negatively correlated with hypertension and diabetes. Incidences of EC were consistently and those of GC mostly decreasing, whereas incidences of CRC were increasing in most countries/regions, especially in the younger populations. Incidences of LC and PC were also increasing in all age‐gender populations except for younger males. Mortalities were decreasing for EC, GC, and CRC in most countries/regions, and age‐specific trends were observed in PC and LC with a decrease in the younger but an increase in the older population.
Conclusions
On the global scale, higher GI cancer burden was accompanied, for the most part, by factors associated with the so‐called Western lifestyle reflected by high and very high national HDI levels. In countries/regions with very high HDI levels, patients survived longer, and increasing GI cancer cases were observed with increasing national HDI levels. Optimizing GI cancer prevention and improving therapies, especially for patients with comorbid metabolic diseases, are thus urgently recommended.
Prevalence of gastrointestinal cancers was positively correlated with national human development index levels, but negatively with hypertension and diabetes rates. Age‐specific trends were observed in stomach cancer and esophagus cancer for incidence and in liver cancer and pancreatic cancer for mortality, as well as sex‐specific trends for stomach cancer and pancreatic cancer in the elder.These findings suggest that future research has to focus on the specific etiology of gastrointestinal cancers behind these epidemiologic transitions and improve therapeutic strategies for patients with comorbid metabolic diseases.
Liquid biopsy shows promise for cancer screening and diagnostics. This reprint collects recent scientific literature on the identification and application of tumor biomarkers in biological fluids to ...improve the diagnosis of cancer and the identification of optimal therapeutic strategies.
Numerous studies have explored the anti-tumor effect of berberine (BBR), but little clinical evidence guides the use of BBR in cancer patients.
Our aim was to investigate the impact of BBR on various ...cancers in healthy animals to promote the transformation from bench to bed.
PubMed, Embase, Springer, and Cochrane databases were searched from January 2000 to October 2018 for relevant articles.
Only published studies focusing on the relationship between BBR and various cancers in vivo were qualified. Two review authors independently assessed the risk of bias for each study, and any disagreement was resolved by discussion or by involving a third assessor.
A total of 26 studies from 2000 to 2018, focusing on various cancer types, including breast cancer, liver cancer, colorectal cancer, nasopharyngeal carcinoma, lung cancer, gastric cancer, neuroepithelial cancer, endometrial carcinoma, esophageal cancer, tongue cancer, cholangiocarcinoma, and sarcoma were included. Overall, BBR reduced tumor volume (SMD =3.72, 95% CI: 2.89, 4.56, Z = 8.73, p < 0.00001) and tumor weight (SMD =2.35, 95% CI: 1.51, 3.19, Z = 5.50, p < 0.00001) in a linear The dose-response relationship (Pearson r = - 0.6717, p < 0.0001 in tumor volume analysis; Pearson r = - 0.7704, p < 0.0005 in tumor weight analysis). BBR inhibited angiogenesis in tumor tissues (SMD = 4.29, 95% CI: 2.14, 6.44, Z = 3.92, p < 0.00001), but it had no significant effect on the body weight of experimental animals (SMD = 0.11, 95% CI: - 0.70, 0.92, Z = 0.27, p = 0.78). Publication bias was not detected.
BBR exerted anti-tumor effects in a variety of tumors in vivo, especially breast cancer and lung cancer, and the evidence was still insufficient in colorectal cancer and gastric cancer.
Recently, rapid advances have been made in metabolomics-based, easy-to-use early cancer detection methods using blood samples. Among metabolites, profiling of plasma free amino acids (PFAAs) is a ...promising approach because PFAAs link all organ systems and have important roles in metabolism. Furthermore, PFAA profiles are known to be influenced by specific diseases, including cancers. Therefore, the purpose of the present study was to determine the characteristics of the PFAA profiles in cancer patients and the possibility of using this information for early detection.
Plasma samples were collected from approximately 200 patients from multiple institutes, each diagnosed with one of the following five types of cancer: lung, gastric, colorectal, breast, or prostate cancer. Patients were compared to gender- and age- matched controls also used in this study. The PFAA levels were measured using high-performance liquid chromatography (HPLC)-electrospray ionization (ESI)-mass spectrometry (MS). Univariate analysis revealed significant differences in the PFAA profiles between the controls and the patients with any of the five types of cancer listed above, even those with asymptomatic early-stage disease. Furthermore, multivariate analysis clearly discriminated the cancer patients from the controls in terms of the area under the receiver-operator characteristics curve (AUC of ROC >0.75 for each cancer), regardless of cancer stage. Because this study was designed as case-control study, further investigations, including model construction and validation using cohorts with larger sample sizes, are necessary to determine the usefulness of PFAA profiling.
These findings suggest that PFAA profiling has great potential for improving cancer screening and diagnosis and understanding disease pathogenesis. PFAA profiles can also be used to determine various disease diagnoses from a single blood sample, which involves a relatively simple plasma assay and imposes a lower physical burden on subjects when compared to existing screening methods.
