RESUMO
BACKGROUND: Long-term daily practice data on patient-reported benefits of dupilumab for atopic dermatitis (AD) remains limited. OBJECTIVE: To evaluate patient-reported outcome measures (PROMs) and the safety of dupilumab in patients with moderate-to-severe AD over a follow-up period of up to 5 years. METHODS: Data were extracted from the prospective, multicenter BioDay registry (October 2017-2022) of patients with moderate-to-severe AD treated with dupilumab in daily practice. RESULTS: In total 1223 patients, 1108 adults and 115 pediatric patients were included. After ≥1 year of treatment, mean Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), Numeric rating scale (NRS)-pruritus ranged between 7.8 and 8.7, 3.5 and 4.2, and 2.9 and 3.1 in adults, respectively, whilst these patient-reported outcome measures (PROMs) ranged between 8.9 and 10.9, 4.4 and 6.4, and 3.0 and 3.7 in pediatric patients, respectively. At follow-up, overall work impairment decreased from 40.1% to 16.3% to 13.3% in adults. Furthermore, class I obesity and itch-dominant patients generally had less favorable treatment response. Of all patients, 66.8% reported ≥1 adverse event, with conjunctivitis being the most common (33.7%). LIMITATIONS: The overall percentage of missing values for selected PROMs was 26% in adults and 46% in pediatric patients. CONCLUSION: In addition to favorable safety, dupilumab has demonstrated sustained effectiveness across various PROMs, underscoring the treatment benefits from patients' perspectives.

As the possibilities in the treatment of cancer continue to evolve, its early detection and correct diagnosis are becoming increasingly important. From the early detection of cancer to the guidance of oncosurgical procedures new sensitive in vivo diagnostic tools are much needed. Many studies report the Raman spectroscopic detection of malignant and premalignant tissues in different sites of the body with high sensitivities. The great appeal of this technique lies in its potential for in vivo clinical implementation. We present an overview of the in vitro and in vivo work on the oncological application of Raman spectroscopy and discuss its potential as a new tool in the clinico-oncological practice. Opportunities for integration of Raman spectroscopy in oncological cure and care as a real-time guidance tool during diagnostic (i.e. biopsy) and therapeutic (surgical resection) modalities as well as technical shortcomings are discussed from a clinician's point of view.

An expanding body of literature suggests Raman spectroscopy is a promising tool for skin cancer diagnosis and in-vivo tumor border demarcation. The development of an in-vivo diagnostic tool is, however, hampered by the fact that construction of fiber optic probes suitable for Raman spectroscopy in the so-called fingerprint region is complicated. In contrast, the use of the high wave-number region allows for fiber optic probes with a very simple design. We investigate whether high wave-number Raman spectroscopy (2800 to 3125 cm(-1)) is able to provide sufficient information for noninvasive discrimination between basal cell carcinoma (BCC) and noninvolved skin. Using a simple fiber optic probe, Raman spectra are obtained from 19 BCC biopsy specimens and 9 biopsy specimens of perilesional skin. A linear discriminant analysis (LDA)-based tissue classification model is developed, which discriminates between BCC and noninvolved skin with high accuracy. This is a crucial step in the development of clinical dermatological applications based on fiber optic Raman spectroscopy.

The objective of this in vitro study was to explore the applicability of Raman spectroscopy to distinguish basal cell carcinoma from its surrounding noncancerous tissue; therefore, identifying possibilities for the development of an in vivo diagnostic technique for tumor border demarcation. Raman spectra were obtained in a two-dimensional grid from unstained frozen sections of 15 basal cell carcinoma specimens. Pseudo-color Raman images were generated by multivariate statistical analysis and clustering analysis of spectra and compared with histopathology. In this way a direct link between histologically identifiable skin layers and structures and their Raman spectra was made. A tissue classification model was developed, which discriminates between basal cell carcinoma and surrounding nontumorous tissue, based on Raman spectra. The logistic regression model, shows a 100% sensitivity and 93% selectivity for basal cell carcinoma. The Raman spectra were, furthermore, used to obtain information about the differences in molecular composition between different skin layers and structures. An interesting finding was that in four samples of nodular basal cell carcinoma, the collagen signal contribution in spectra of dermis close to a basal cell carcinoma, was markedly reduced. The study demonstrates the sensitivity of Raman spectroscopy to biochemical changes in tissue accompanying malignancy, resulting in a high accuracy when discriminating between basal cell carcinoma and noncancerous tissue.
