Recommendations for the management of cutaneous squamous cell carcinoma: a systematic multidisciplinary Delphi consensus approach.

Background: There are gaps and unanswered questions in clinical guidelines regarding several aspects of the management of patients with cutaneous squamous cell carcinoma (cSCC).

Methods: A scientific committee of ten cSCC specialists in Spain (dermatology, medical oncology, oral and maxillofacial surgery, plastic surgery, and radiotherapy) used ADAPTE methodology to develop recommendations by: (i) identifying clinical questions not fully answered by clinical practice guidelines; (ii) systematically reviewing the literature (published between November 2017 and July 2023 in PubMed and the Cochrane database) and grading the evidence (using Oxford levels); (iii) developing recommendations and assessing those with no consensus among the scientific committee or with evidence level 3-5 or strength of recommendation under C or D in a two-round Delphi method; and (iv) developing the final recommendations in the form of answers to key clinical questions, grading the strength of recommendation. An external group of 32 experts plus the members of the committee participated in both Delphi rounds, evaluating the appropriateness and need of the recommendations.

SEOM clinical guidelines for cancer anorexia-cachexia syndrome (2023).

Cancer-related anorexia-cachexia syndrome (CACS) is a debilitating condition afflicting up to 80% of advanced-stage cancer patients. Characterized by progressive weight loss, muscle wasting, and metabolic abnormalities, CACS significantly compromises patients' quality of life and treatment outcomes. This comprehensive review navigates through its intricate physiopathology, elucidating its stages and diagnostic methodologies.

Treatment of metastatic squamous cell carcinoma arising in sacrococcygeal pilonidal sinus: a case report series.

Background: Squamous cell carcinoma (SCC) arising in a sacrococcygeal pilonidal sinus is rare, with cases of metastatic disease being even rarer. Among published cases, almost none have reported on systemic treatment.

Objective: This disease has a poorer prognosis than other forms of cutaneous SCC; therefore, our objective is to shed some light on the treatment of metastatic disease.

Recommendations for the use of biomarkers for head and neck cancer, including salivary gland tumours: A Consensus of the Spanish Society of Medical Oncology and the Spanish Society of Pathology.

The treatment of head and neck and salivary gland tumours is complicated and is constantly evolving. Prognostic and predictive indicators of response to treatment are enormously valuable for designing individualized therapies, which justifies their research and validation. Some biomarkers, such as p16, Epstein-Barr virus, PD-L1, androgen receptors and HER-2, are already used routinely in clinical practice.

Limited T cell response to SARS-CoV-2 mRNA vaccine among patients with cancer receiving different cancer treatments.

Introduction: Patients with cancer (PC) are at high risk of acquiring COVID-19 and can develop more serious complications. Deeper understanding of vaccines immunogenicity in this population is crucial for adequately planning vaccines programs. The ONCOVac study aimed to comprehensively assess the immunogenicity of mRNA-1273 vaccine in terms of humoral and cellular response.

Sarcoidosis-like reactions in cancer patients treated with immune checkpoint inhibitors: experience in a Spanish hospital.

Background: Immune checkpoint inhibitors (ICI) have been associated with several immune-related adverse events, including sarcoidosis-like reactions (SLR). SLR, which has a low prevalence but an increasing incidence, is similar to sarcoidosis in terms of histology, and clinical and radiological manifestations. The most commonly affected organs are hilar and mediastinal lymph nodes and skin.

Intratumoral nanoplexed poly I:C BO-112 in combination with systemic anti-PD-1 for patients with anti-PD-1-refractory tumors.

Intratumoral therapies, especially Toll-like receptor agonists, can trigger both the innate and adaptive immune systems. BO-112 is a nanoplexed form of polyinosinic:polycytidylic acid (poly I:C) that induces local and systemic immunotherapeutic effects in mouse models. In a multicenter phase 1 clinical trial, repeated intratumoral administrations of BO-112 induced an increase in tumor cell necrosis and apoptosis, as well as augmented immune reactivity according to gene expression profiling.

Diagnosis and Treatment of Basal Cell Carcinoma in Specialized Dermatology Units: A Clinical Practice Guideline.

Background And Objective: Basal cell carcinoma (BCC) is the most common skin cancer in the general population. BCC is managed in a variety of ways, and available international guidelines are difficult to put into practice in Spain. This guideline aims to improve the management of BCC based on current evidence and provide a point of reference for Spanish dermatologists.
