Laser-Based Test Hunts Stray Melanoma Cells

The researchers have been developing a laser-based system designed to screen patients' blood from the outside -- spotting tumor cells as they pass through veins in the arm and eliminating the need for a blood draw.

Authors: Wang B, Tian Y, Yin Q Abstract AIM2 (absent in melanoma 2) is a cytoplasmic sensor of double-stranded DNA from pathogens or damaged cellular organelles. It recruits ASC (apoptosis-associated specklike protein containing a CARD) and caspase-1 to form the AIM2 inflammasome, activate caspase-1, and elicit inflammatory responses via cytokine maturation and pyroptotic cell death. Structural studies from X-ray crystallography, NMR, and cryo-EM have revealed many details in AIM2 inflammasome activation, assembly, and regulation. Many principles learned from AIM2 inflammasome also apply to other inflammasomes. In ...

In this report, we analyzed gene expression profiles of paired specimens of keratinocyte carcinomas with their matched normal skin tissues as the control. Among several novel findings, we discovered a significant number of zinc finger encoding genes up-regulated in human BCC. In BCC, a novel link was found between hedgehog signaling, Wnt signaling, and the cilium. While the SCC cancer-stem-cell gene signature is shared between human and mouse SCCs, the hair follicle stem-cell signature of mice was not highly represented in human SCC. Differential gene expression (DEG) in human BCC shares gene signature with both bulge and ...

Conclusion We present a complete overview of artificial intelligence implemented in dermatology. Impressive outcomes were reported in all of the identified eight categories, but head-to-head comparison proved difficult. The many areas of dermatology where we identified machine learning tools indicate the diversity of machine learning. PMID: 31625775 [PubMed - as supplied by publisher]

Authors: Philipp-Dormston WG, Battistella M, Boussemart L, Di Stefani A, Broganelli P, Thoms KM Abstract Introduction: Actinic keratosis (AK) is a chronic skin condition that can be a precursor to cutaneous squamous cell carcinoma. AK can recur and patients are likely to undergo multiple treatments. It is important that AK lesions are managed appropriately, and that patients are involved in treatment decisions. Materials and methods: The Supporting Professional Expertise in AK (SPEAK) program aims to facilitate this patient-centered care by identifying patient needs and aiding healthcare practitioners (HCPs) in sel...

In conclusion, the DEGs and hub genes identified in the present study may be used to understand the molecular pathways involved in the initiation and progression of malignant melanoma. Furthermore, the present study may aid in the identification of possible targets for the diagnosis and treatment of melanoma. PMID: 31620197 [PubMed]

The advent of BRAF and MEK inhibitors changed the landscape of the management of BRAF mutated melanoma patients. In this article, we report the case of a 51-year-old man with BRAF mutated locally advanced cutaneous melanoma of the head who demonstrated a limited response to initial anti-BRAF monotherapy followed by extensive surgery. Anti-PD1 therapy failed to reverse the disease progression. However, subsequent double inhibition of the BRAF and MEK pathways induced a fast and remarkable tumour response.

We describe a case of multiple cutaneous metastases from gastric cancer resembling sebaceous cysts with a synchronous melanoma, in a patient after fluoropyrimidine-based systemic chemotherapy. Melanoma occurring as a second cancer has been recognized in patients having undergone previous chemotherapy or radiation for another cancer. We can assume that the capecitabine-based chemotherapy may have played a role in the development of the melanocytic neoplasm. Our observation adds extra evidence to the link between fluoropyrimidine-based immunosuppression and the induction of melanocytes’ proliferation and transformation...
