Prospective manipulation of the gut microbiome with microbial ecosystem therapeutic 4 (MET4) in HPV-related locoregionally-advanced oropharyngeal cancer squamous cell carcinoma (LA-OPSCC) undergoing primary chemoradiation: ROMA2 study.

Background: Gut microbiome modulation to boost antitumor immune responses is under investigation.

Methods: ROMA-2 evaluated the microbial ecosystem therapeutic (MET)-4 oral consortia, a mixture of cultured human stool-derived immune-responsiveness associated bacteria, given with chemoradiation (CRT) in HPV-related oropharyngeal cancer patients. Co-primary endpoints were safety and changes in stool cumulative MET-4 taxa relative abundance (RA) by 16SRNA sequencing.

Contouring aid tools in radiotherapy. Smoothing: the false friend.

Objective: Contouring accuracy is critical in modern radiotherapy. Several tools are available to assist clinicians in this task. This study aims to evaluate the performance of the smoothing tool in the ARIA system to obtain more consistent volumes.

Is ranitidine necessary as premedication for regimens containing paclitaxel? A non-inferiority study.

Background: Histamine type-2-receptor antagonist drugs (H2-antagonists) have been used as standard treatment to prevent hypersensitivity reactions (HRs) in paclitaxel-containing regimens, however, their use has been strongly questioned. Ranitidine has been the most widely used H2-antagonist. Therefore, especially after its withdrawal from the market, the objective of this study is to determine the impact of its elimination from premedication on HR incidence.

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.

SEOM clinical guidelines for the treatment of nasopharyngeal carcinoma.

Nasopharyngeal carcinoma is an unusual tumour in Spain. It has differences in epidemiology, histology, clinical behaviour, treatment and prognosis from those of other head and neck neoplasms, which justifies separate analysis. It is a neoplasm with a high possibility of cure with a combined treatment if even it is diagnosed in an advanced locoregional stage (stage III or IV, without metastasis).

SEOM clinical guidelines for the treatment of head and neck cancer.

Head and neck cancer constitutes the fifth highest cause of cancer in Spain. It is a neoplasm with a high possibility of cure if it is diagnosed in early stages, but unfortunately two thirds of the patients are diagnosed at an advanced loco-regional stage (stage III and IV, without metastasis). The multidisciplinary team, bringing together all professionals who specialize in the diagnosis and treatment of these tumors make the decision to establish the best sequence of individualized diagnosis, staging and treatment for each patient.
