Mixed neuroendocrine non-neuroendocrine neoplasms in gastroenteropancreatic tract.

Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are a heterogeneous group of malignant neoplasms that can settle in the gastroenteropancreatic tract. They are composed of a neuroendocrine (NE) and a non-NE component in at least 30% of each tumour. The non-NE component can include different histological combinations of glandular, squamous, mucinous and sarcomatoid phenotypes, and one or both of the components can be low-or high grade malignant.

Neoplastic appendiceal mucinous lesions: a narrative review of the literature from an oncologist's perspective.

Appendiceal mucinous lesions' classification and nomenclature has been modified several times along the last decades, reflecting their great heterogeneity and making difficult to compare results and draw conclusions. Despite its nearby origin, appendiceal mucinous lesions have a distinctive behaviour compared to colorectal cancer, including their molecular and genetic markers. Due to their low frequency, their management is not well standardised.

TTCC-2019-02: real-world evidence of first-line cetuximab plus paclitaxel in recurrent or metastatic squamous cell carcinoma of the head and neck.

Objectives: The aim of this study was to confirm the efficacy of the ERBITAX scheme (paclitaxel 80 mg/m weekly and cetuximab 400 mg/m loading dose, and then 250 mg/m weekly) as first-line treatment for patients with recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN) who are medically unfit for cisplatin-based (PT) chemotherapy.

Materials And Methods: This retrospective, non-interventional study involved 16 centers in Spain. Inclusion criteria were to have started receiving ERBITAX regimen from January 2012 to December 2018; histologically confirmed SCCHN including oral cavity, oropharynx, hypopharynx, and larynx; age ≥18 years; and platinum (PT) chemotherapy ineligibility due to performance status, comorbidities, high accumulated dose of PT, or PT refractoriness.

Lenvatininb as Treatment for Naïve Patients with Aggressive Thyroid Cancer Bone Metastases and Bad Performance Status.

Lenvatinib is an oral multityrosine kinase inhibitor (TKI) with proven effectiveness in the treatment of radioactive iodine- (RAI-) refractory and/or unresectable differentiated thyroid carcinoma (DTC). The present study reports the case of a 41-year-old male who underwent hemithyroidectomy in June 2015 due to a thyroid nodule with fine-needle aspiration follicular neoplasm cytology and no evidence of malignancy in the histopathological exam. Three years later, acute disabling clinical symptoms emerged, mainly high skeletal pain conditioned with an important performance status decrease.

Afatinib vs Placebo as Adjuvant Therapy After Chemoradiotherapy in Squamous Cell Carcinoma of the Head and Neck: A Randomized Clinical Trial.

Importance: Locoregionally advanced head and neck squamous cell cancer (HNSCC) is treated curatively; however, risk of recurrence remains high among some patients. The ERBB family blocker afatinib has shown efficacy in recurrent or metastatic HNSCC.

Objective: To assess whether afatinib therapy after definitive chemoradiotherapy (CRT) improves disease-free survival (DFS) in patients with HNSCC.

Prevention of oral mucositis secondary to antineoplastic treatments in head and neck cancer by supplementation with oral glutamine.

Objectives: to evaluate the efficacy of glutamine in the prevention of the incidence of oral mucositis secondary to cancer therapies in patients with head and neck cancer (HNC). Secondary objectives were to know the incidence of odynophagia, interruptions of treatment and the requirements of analgesia and nasogastric tube.

Material And Methods: prospective cohort study of patients with squamous cell carcinoma of HNC treated with radiotherapy ± concomitant chemotherapy.

Phosphorylation of gH2AX as a novel prognostic biomarker for laryngoesophageal dysfunction-free survival.

Current larynx preservation treatments have achieved an improvement of laryngoesophageal dysfunction-free survival (LDS) but lead to significant toxicities and recurrences. At present, there is no evidence to select the group of patients that may benefit from preservation approaches instead of surgery. Therefore, laryngeal biomarkers could facilitate pretreatment identification of patients who could respond to chemoradiation-based therapy.

A genetic view of laryngeal cancer heterogeneity.

During the recent decades significant improvements in the understanding of laryngeal molecular biology allowed a better characterization of the tumor. However, despite increased molecular knowledge and clinical efforts, survival of patients with laryngeal cancer remains the same as 30 years ago. Although this result may not make major conclusions as preservation approaches were not broadly used until the time of database collection, it seems to be clear that there is still window for improvement.

MAP17 (PDZKIP1) as a novel prognostic biomarker for laryngeal cancer.

Larynx cancer organ preservation treatments with chemo and radiotherapy have substantially improved laryngoesophageal dysfunction-free survival. However, both of them lead to a high incidence of acute and chronic toxicities and a significant number of patients relapse. To date, there is no evidence available to establish the group of patients that may benefit from preservation approaches and clinical criteria such as primary tumor extension or pretreatment tracheotomy are not validated.

A colorectal cancer susceptibility new variant at 4q26 in the Spanish population identified by genome-wide association analysis.

Background: Non-hereditary colorectal cancer (CRC) is a complex disorder resulting from the combination of genetic and non-genetic factors. Genome-wide association studies (GWAS) are useful for identifying such genetic susceptibility factors. However, the single loci so far associated with CRC only represent a fraction of the genetic risk for CRC development in the general population.

Genetic analysis of caveolin-1 and eNOS genes in colorectal cancer.

Caveolae are involved in physical compartmentalization between different groups of signaling events. Its main component, CAV1, modulates different pathways in cellular physiology. The emerging evidence pointing to the role of CAV1 in cancer led us to study whether different alleles of this gene are associated with colorectal cancer (CRC).
