Special Issue Information

Dear Colleagues,

Despite current advances in surgery and other treatment options, the fatality of some cancers has remained mostly unchanged. Studies have shown that phytochemicals have the capability to prevent carcinogenesis. Therefore, new active compounds responsible for the anti-cancer characteristics of dietary plants, and original active compounds exert novel function on anti-carcinogenesis, are important issues in cancer investigation. We invite the researchers to contribute original and review articles regarding the relationship between phytochemicals and cancers, including the discovery of novel anti-cancer phytochemicals and the novel signalling pathways, and signalling molecules of phytochemicals on cancer treatment. We are pleased to invite you to our Special Issue on “Advances in Cancer Chemoprevention and Therapeutics”. We look forward to receiving your contributions.

Prof. Dr. Shun-Fa Yang

Organochlorine pesticides (OCPs) are a class of environmentally persistent and bioaccumulative pollutants. Among these, β-hexachlorocyclohexane (β-HCH) is a byproduct of lindane synthesis, one of the most worldwide widespread pesticides. β-HCH cellular mechanisms inducing chemical carcinogenesis correspond to many of those inducing chemoresistance, in particular, by the activation of signal transducer and activator of transcription 3 (STAT3) signaling pathways. For this purpose, four cell lines, representative of breast, lung, prostate, and hepatocellular cancers, were treated with β-HCH, specific tyrosine kinase inhibitors (TKIs), and a STAT3 inhibitor. All cell samples were analyzed by a viability assay, immunoblotting analysis, a wound-healing assay, and a colony formation assay. The results show that β-HCH reduces the efficacy of TKIs. The STAT3 protein, in this context, plays a central role. In fact, by inhibiting its activity, the efficacy of the anticancer drug is restored. Furthermore, this manuscript aimed to draw the attention of the scientific and socio-healthcare community to the issue of prolonged exposure to contaminants and their impact on drug efficacy.

Colorectal cancer (CRC) is one of the deadliest forms of cancer worldwide. CRC development occurs mainly through the adenoma-carcinoma sequence, which can last decades, giving the opportunity for primary prevention and early detection. CRC prevention involves different approaches, ranging from fecal occult blood testing and colonoscopy screening to chemoprevention. In this review, we discuss the main findings gathered in the field of CRC chemoprevention, focusing on different target populations and on various precancerous lesions that can be used as efficacy evaluation endpoints for chemoprevention. The ideal chemopreventive agent should be well tolerated and easy to administer, with low side effects. Moreover, it should be readily available at a low cost. These properties are crucial because these compounds are meant to be used for a long time in populations with different CRC risk profiles. Several agents have been investigated so far, some of which are currently used in clinical practice. However, further investigation is needed to devise a comprehensive and effective chemoprevention strategy for CRC. Full article

There are hereditary mutations that predispose individuals to cancer development, such as pathogenic variants in the germ line of the tumor protein 53 (TP53) suppressor gene. This leads to a rare condition known as Li–Fraumeni syndrome (LFS), characterized by a high risk of developing multiple cancers throughout life by the precancerous niche that promotes the tumor microenvironment. LFS presents a significant challenge due to its limited therapeutic and chemoprophylactic options. Recently, protocols involving metformin as a prophylactic medication have been developed to target precancerous niches. However, this approach is still in the clinical phase, and no established therapeutic regimen is available. Therefore, new alternatives are needed to impact this disease effectively. Novel studies suggest that Sechium extract, rich in polyphenols, exhibits chemoprophylactic, antineoplastic, anti-inflammatory, and antioxidant activities, all involved in the tumor microenvironment of LFS. However, the specific role of Sechium extract in preventing recurrent neoplastic development in LFS remains unclear. We conducted this research through a case report of an LFS-diagnosed patient who has experienced multiple malignancies and cutaneous neoformations. This patient received a chemoprophylactic supplementation based on Sechium H387 07 extract over 11 years without reporting new primary malignancy events or recurrences, as evidenced by laboratory and positron emission tomography/computed tomography (PET/CT) studies. An extensive literature review on the disease, precancerous niche, tumor microenvironment, and potential mechanisms of Sechium H387 07 extract components was conducted to explain cancer absence in LFS. This review promotes the research and use of polyphenols as powerful chemoprophylactic agents to prevent and treat proliferative diseases like LFS. Full article
