Exploring the potential of photodynamic therapy in the treatment of non-melanoma skin cancer: Analysis of two clinical cases.

This article presents two cases of non-melanoma skin cancer treated with photodynamic therapy (PDT). The first case involved a 74-year-old woman with a 4 cm basal cell carcinoma on her right zygomatic region, while the second case involved a 83-year-old woman with a 6 cm squamous cell carcinoma on her left peri‑auricular area. Both patients underwent two sessions of systemic PDT, with chlorin E6 (Photoran) as the photosensitizer, followed by red light illumination.

The Ring Study: an international comparison of PD-L1 diagnostic assays and their interpretation in non-small cell lung cancer, head and neck squamous cell cancer and urothelial cancer.

PD-L1 immunohistochemistry has been approved as a diagnostic assay for immunotherapy. However, an international comparison across multiple cancers is lacking. This study aimed to assess the performance of PD-L1 diagnostic assays in non-small cell lung cancer (NSCLC), head and neck squamous cell cancer (HNSCC) and urothelial cancer (UC).

Cobimetinib plus atezolizumab in BRAF wild-type melanoma: primary results from the randomized phase III IMspire170 study.

Background: Emerging data suggest that the combination of MEK inhibitors and immunotherapeutic agents may result in improved efficacy in melanoma. We evaluated whether combining MEK inhibition and immune checkpoint inhibition was more efficacious than immune checkpoint inhibition alone in patients with previously untreated BRAF wild-type advanced melanoma.

Patients And Methods: IMspire170 was an international, randomized, open-label, phase III study.

Agreement between PDL1 immunohistochemistry assays and polymerase chain reaction in non-small cell lung cancer: CLOVER comparison study.

The goal of the CLOVER study was to perform a pairwise comparison of four tests based on the same patient population with non-small cell lung cancer (NSCLC): three validated PDL1 immunohistochemistry (IHC) assays (Ventana SP142, Ventana SP263, Dako 22C3) and one PCR test. Four hundred seventy-three NSCLC samples were obtained from a biobank and were stained using PDL1 IHC assays. Four trained pathologists independently evaluated the percentage of tumor cells (TC) and immune cells (IC) that stained positive at any intensity.

Feasibility of clinical electron beam formation using polymer materials produced by fused deposition modeling.

The main challenge in electron external beam radiation therapy with clinical accelerators is the absence of integrated systems to form irregular fields. The current approach to provide conformal irradiation is to use additional metallic shaping blocks, with inefficient and expensive workflows. This work presents a simple method to form therapeutic electron fields using 3D printed samples.

[Intracorporeal anastomosis in laparoscopic right hemicolectomy: a review of evidence and a single-center experience].

Laparoscopic colon resections are currently becoming a standart method of surgical treatment of colon cancer. Long-term oncologic outcomes of such procedures are shown to be non-inferior to outcomes of traditional open surgery, while short-term results and morbidity profile are more favourable. The current direction of colon mini-invasive surgery development is to make procedures more easily tolerable by patients, using less traumatic methods and operative approaches.

Comparison of dabrafenib and trametinib combination therapy with vemurafenib monotherapy on health-related quality of life in patients with unresectable or metastatic cutaneous BRAF Val600-mutation-positive melanoma (COMBI-v): results of a phase 3, open-label, randomised trial.

Background: In the COMBI-v trial, patients with previously untreated BRAF Val600Glu or Val600Lys mutant unresectable or metastatic melanoma who were treated with the combination of dabrafenib and trametinib had significantly longer overall and progression-free survival than those treated with vemurafenib alone. Here, we present the effects of treatments on health-related quality of life (HRQoL), an exploratory endpoint in the COMBI-v study.

Methods: COMBI-v was an open-label, randomised phase 3 study in which 704 patients with metastatic melanoma with a BRAF Val600 mutation were randomly assigned (1:1) by an interactive voice response system to receive either a combination of dabrafenib (150 mg twice-daily) and trametinib (2 mg once-daily) or vemurafenib monotherapy (960 mg twice-daily) orally as first-line therapy.

Health-related quality of life impact in a randomised phase III study of the combination of dabrafenib and trametinib versus dabrafenib monotherapy in patients with BRAF V600 metastatic melanoma.

Aim: To present the impact of treatments on health-related quality of life (HRQoL) from the double-blind, randomised phase III COMBI-d study that investigated the combination of dabrafenib and trametinib versus dabrafenib monotherapy in patients with BRAF V600E/K-mutant metastatic melanoma. COMBI-d showed significantly prolonged progression-free survival for the combination.

Methods: HRQoL was evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30, a generic cancer questionnaire (completed at baseline, during study treatment, at progression and post progression) assessing various dimensions (global health/QoL, functional status, and symptom impact).

Combined vemurafenib and cobimetinib in BRAF-mutated melanoma.

Background: The combined inhibition of BRAF and MEK is hypothesized to improve clinical outcomes in patients with melanoma by preventing or delaying the onset of resistance observed with BRAF inhibitors alone. This randomized phase 3 study evaluated the combination of the BRAF inhibitor vemurafenib and the MEK inhibitor cobimetinib.

Methods: We randomly assigned 495 patients with previously untreated unresectable locally advanced or metastatic BRAF V600 mutation-positive melanoma to receive vemurafenib and cobimetinib (combination group) or vemurafenib and placebo (control group).

Sensitive genotyping of somatic mutations in the EGFR, KRAS, PIK3CA, BRAF genes from NSCLC patients using hydrogel biochips.

Targeted inhibitors of the epidermal growth factor receptor (EGFR) are used for the treatment of non-small cell lung cancer (NSCLC). Somatic mutations in the EGFR gene and key effectors of the EGFR-signaling pathway (KRAS, BRAF, PIK3CA) are associated with sensitivity to these drugs. We developed a highly sensitive LUNG CANCER (LC)-biochip approach for the detection of the most common EGFR, KRAS, PIK3CA, and BRAF gene mutations.
