Strychnine (STCN) has demonstrated an exceptional anticancer effect against various cancers. However, the STCN clinical utility has been hampered by its low water solubility, restricted therapeutic window, short half-life, and significant toxicity. The objective of this investigation was to design and optimize a formulation of strychnine-loaded transliposomes (STCN-TLs) for dermal administration of STCN to treat skin cancer. The formulations of STCN-TL were examined in terms of vesicle size (VS), polydispersity index (PDI), entrapment efficiency (EE), and in vitro delivery. The improved STCN-TL formulation exhibited VS, PDI, EE, and in vitro delivery of 101.5 ± 2.14 nm, 0.218 ± 0.12, 81.74 ± 1.43%, and 85.39 ± 2.33%, respectively. In an ex vivo penetration, the created STCN-TL formulation demonstrated a 2.5-fold increase in permeability compared to the STCN solution. CLSM pictures of skin (rat) revealed that the rhodamine B-loaded transliposome preparation penetrated deeper than the rhodamine B hydroalcoholic mixture. Additionally, rat skin managed with STCN-TL nanogel exhibited a significant increase in C and AUC compared to rat skin treated with traditional STCN gel. The findings demonstrated that the transliposome preparation might be a suitable nanocarrier for the cutaneous distribution of STCN in the amelioration of skin cancer.

Importance: Cutaneous chronic graft-vs-host disease (GVHD) is independently associated with morbidity and mortality after allogeneic hematopoietic cell transplant. However, the health-related quality-of-life (HRQOL) domains that are most important to patients are poorly understood.
Objective: To perform a concept elicitation study to define HRQOL in cutaneous chronic GVHD from the patient perspective and to compare experiences of patients with epidermal vs sclerotic disease.

Cutaneous squamous cell carcinoma (cSCC) incidence and deaths continue to rise, underscoring the need for improved cSCC prevention. Elimination of actinic keratosis (AK) precursor lesions is a major strategy to prevent cSCC. Topical calcipotriol and 5-fluorouracil (5-FU) have been shown to eliminate AKs and reduce the risk of cSCC development, but the mechanism was undefined.

The continuous rise in skin cancer incidence highlights an imperative for improved skin cancer prevention. Topical calcipotriol-plus-5-fluorouracil (calcipotriol-plus-5-FU) immunotherapy effectively eliminates precancerous skin lesions and prevents squamous cell carcinoma (SCC) in patients. However, its mechanism of action remains unclear.

Background/aims: People with disability have higher rates of cancer, excluding skin cancer, compared with people without disability. Food and Drug Administration draft guidelines from 2024 address use of performance status criteria to determine eligibility for clinical trials, advocating for less restrictive thresholds. We examined the exclusion of people with disability from clinical trials based on performance status and other criteria.

Breast cancer remains one of the most prevalent malignancies among women globally. Despite advances in therapeutic options, the prognosis often remains challenging. Breast cancer typically originates in the epithelial lining of glandular tissue ducts (85%) or lobules (15%).
