Unconventional Remedies for Squamous Cell Carcinoma: A Journey into Alternative Treatments

Squamous cell carcinoma (SCC) is the second most common form of skin cancer and is typically found on sun-exposed skin. Risk factors include ultraviolet radiation exposure, older age, fairer complexion, smoking, and immunosuppression. SCC is a slow-growing tumor with the possibility of metastasis if not treated. The clinical presentation can range from a dry, scaly erythematous patch or plaque to a firm hyperkeratotic papule, plaque, or nodule, depending on the histological type via biopsy. The first-line therapies for SCC removal are standard excision and Mohs microscopic surgery; however, there are novel and alternative non-surgical options being considered for the treatment of SCC. This review summarizes the current guidelines for treating low-risk and high-risk SCC and discusses rare, experimental, and anecdotal non-surgical treatments for SCC in the literature.

Skin cancer: understanding the journey of transformation from conventional to advanced treatment approaches

Skin cancer is a global threat to the healthcare system and is estimated to incline tremendously in the next 20 years, if not diagnosed at an early stage. Even though it is curable at an early stage, novel drug identification, clinical success, and drug resistance is another major challenge. To bridge the gap and bring effective treatment, it is important to understand the etiology of skin carcinoma, the mechanism of cell proliferation, factors affecting cell growth, and the mechanism of drug resistance. The current article focusses on understanding the structural diversity of skin cancers, treatments available till date including phytocompounds, chemotherapy, radiotherapy, photothermal therapy, surgery, combination therapy, molecular targets associated with cancer growth and metastasis, and special emphasis on nanotechnology-based approaches for downregulating the deleterious disease. A detailed analysis with respect to types of nanoparticles and their scope in overcoming multidrug resistance as well as associated clinical trials has been discussed.

Evaluating Potentials of Species Rich Taxonomic Groups in Cosmetics and Dermatology: Clustering and Dispersion of Skin Efficacy of Asteraceae and Ranunculales Plants on the Species Phylogenetic Tree

BACKGROUND

The medicinal properties of plants can be predicted by virtue of phylogenetic methods, which nevertheless have not been utilized to explore the regularity of skin-related bioactivities of ethnomedicinal plants. We aim to investigate the distribution of skin efficacy of Asteraceae and Ranunculales plants on the species-level Tree of Life.

METHODS

The clinical efficacy data of 551 ethnomedicinal species belonging to Ranunculales, as well as 579 ethnomedicinal species of Asteraceae, were systematically collected and collated; these therapeutic data fell into 15 categories, including skin disease/cosmeceutical. The large phylogenetic tree of all China angiosperm species was used to detect the phylogenetic signals of ethnomedicinal plants by calculating the D statistic, phylogenetic diversity (PD), net relatedness index (NRI), and nearest taxon index (NTI). Of all Chinese ethnomedicinal plants of Ranunculales and Asteraceae, 339 (61.5% of all ethnomedicinal species) and 382 (66.0% of all) are used for skin problems. In Ranunculales, a clustered structure was suggested by the NRI value for skin uses. In Asteraceae, the skin utility was not clustered; Artemisia, Aster, Cremanthodium, Ligularia, and Saussurea are the most used Asteraceae genera for skin issues.

RESULTS

The clustering structure was identified in Artemisia, and the skin efficacy in other genera was of overdispersion (NRI < 0). NTI values and D statistics largely agree with NRI. When compared with PD values of different therapeutic categories, the PD value of the skin category was relatively high in Cremanthodium, Ranunculales, Asteraceae, and Artemisia, suggesting the enormous efficacy space in the new taxa of these taxonomic groups.

CONCLUSION

By resolving the distribution of therapeutic effects of Ranunculales/Asteraceae taxa, the importance of phylogenetic methods in mining botanical resources with skin utilities is validated.

Effects of Carbon Nanomaterials and Aloe vera on Melanomas-Where Are We? Recent Updates

Melanoma is an aggressive skin cancer that affects approximately 140,000 people worldwide each year, with a high fatality rate. Available treatment modalities show limited efficacy in more severe cases. Hence, the search for new treatment modalities, including immunotherapies, for curing, mitigating, and/or preventing cancer is important and urgently needed. Carbon nanoparticles associated with some plant materials, such as Aloe vera, have shown appealing antineoplastic activity, derived mainly from the compounds aloin, aloe-emodin, barbaloin acemannan, and octapeptide, thus representing new possibilities as antitumor agents. This systematic review aims to arouse interest and present the possibilities of using Aloe vera combined with carbon-based nanomaterials as an antineoplastic agent in the treatment and prevention of melanoma. Limitations and advances in melanoma treatment using functionalized carbon nanomaterials are discussed here. Moreover, this review provides the basis for further studies designed to fully explore the potential of carbon nanomaterials associated with Aloe vera in the treatment of various cancers, with a focus on melanoma.

Quemadura química por Sanguinaria canadensis

La Sanguinaria canadensis, o Bloodroot, es una planta originaria de Norteamérica que contiene sustancias alcaloides y es ampliamente empleada en el tratamiento de lesiones y tumores de la piel en animales. Sin embargo, en los últimos años ha aumentado su uso en humanos como terapia alternativa en el tratamiento de lesiones precancerosas y cáncer de piel. Su uso inadecuado en humanos puede causar lesiones graves y profundas en la piel. Presentamos el caso de un paciente joven que por voluntad propia se aplicó un preparado de Sanguinaria canadensis (Bloodroot paste) para eliminar dos nevus cutáneos, produciéndole lesiones extensas que requirieron tratamiento y curas hasta su cierre por segunda intención, dejando cicatrices hipertróficas como secuela. Palabras clave: Sanguinaria, úlcera cutánea, heridas penetrantes.

Tetrahydrocannabinol and Skin Cancer: Analysis of YouTube Videos

BACKGROUND

Cannabis oil is being used topically by patients with skin cancer as a homeopathic remedy, and has been promoted and popularized on social media, including YouTube. Although topical cannabinoids, especially tetrahydrocannabinol (THC), may have antitumor effects, results from a sparse number of clinical trials and peer-reviewed studies detailing safety and efficacy are still under investigation.

OBJECTIVE

We sought to assess the accuracy, quality, and reliability of THC oil and skin cancer information available on YouTube.

METHODS

The 10 most-viewed videos on THC oil and skin cancer were analyzed with the Global Quality Scale (GQS), DISCERN score, and useful/misleading criteria based on presentation of erroneous and scientifically unproven information. The videos were also inspected for source, length, and audience likes/dislikes. Top comments were additionally examined based on whether they were favorable, unfavorable, or neutral regarding the video content.

RESULTS

All analyzed videos (10/10, 100%) received a GQS score of 1, corresponding to poor quality of content, and 9/10 (90%) videos received a DISCERN score of 0, indicating poor reliability of information presented. All 10 videos were also found to be misleading and not useful according to established criteria. Top comments were largely either favorable (13/27, 48%) or neutral (13/27, 48%) toward the content of the videos, compared to unfavorable (1/27, 4%).

CONCLUSIONS

Dermatologists should be aware that the spread of inaccurate information on skin cancer treatment currently exists on popular social media platforms and may lead to detrimental consequences for patients interested in pursuing alternative or homeopathic approaches.
