Clinical outcomes and toxicity after exclusive versus postoperative radiotherapy in supraglottic cancer: new solutions for old problems? The case of stage I and II disease.

PURPOSE: To compare acute and late toxicities, survival, and laryngeal preservation after radiotherapy alone (RR) or radiotherapy after partial laryngectomy (PLR) in early supraglottic laryngeal cancer. MATERIALS AND METHODS: From 1984 to 2012, 172 patients were treated in our department. We analyzed and compared toxicities (CTCAE v 4.0), overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), local relapse-free survival (LRFS), nodal relapse-free survival (NRFS), metastasis-free survival (MFS), and the number of salvage total laryngectomies. RESULTS: Patients in the RR group were older (p = 0.05) and had more often comorbidities (p = 0.025); those in the PLR group had mostly T2 disease (p = 0.014). No difference in number of local, nodal, and distant recurrences was found. A higher incidence of late mild dry mouth in patients treated with RR (38 vs. 4 %, p = 0.000) was reported. At univariate analysis, only a younger age, a better performance status, and the absence of comorbidities favorably impacted on OS and DSS. No differences were found in DFS, LRFS, NRFS, MFS, and the number of rescue laryngectomies between the two groups. Younger age and a good performance status persisted as a predictive factor of better survival (OS and DSS) at multivariate analysis. CONCLUSION: Radical radiotherapy appears to be a viable alternative to conservative surgery, even in elderly patients with poor performance status and comorbidities. Salvage laryngectomy in the RR group was compared favorably with those reported in other conservative surgery series and in the group treated postoperatively of our series.

Oral toxicity management in head and neck cancer patients treated with chemotherapy and radiation: Dental pathologies and osteoradionecrosis (Part 1) literature review and consensus statement.

Radiotherapy alone or in combination with chemotherapy and/or surgery is the typical treatment for head and neck cancer patients. Acute side effects (such as oral mucositis, dermatitis, salivary changes, taste alterations, etc.), and late toxicities in particular (such as osteo-radionecrosis, hypo-salivation and xerostomia, trismus, radiation caries etc.), are often debilitating. These effects tend to be underestimated and insufficiently addressed in the medical community. A multidisciplinary group of head and neck cancer specialists met in Milan with the aim of reaching a consensus on clinical definitions and management of these toxicities. The Delphi Appropriateness method was used for developing the consensus, and external experts evaluated the conclusions. This paper contains 10 clusters of statements about the clinical definitions and management of head and neck cancer treatment sequels (dental pathologies and osteo-radionecroses) that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecroses (10 clusters of statements), whereas this second part deals with trismus and xerostomia.

Oral toxicity management in head and neck cancer patients treated with chemotherapy and radiation: Xerostomia and trismus (Part 2). Literature review and consensus statement.

Radiotherapy alone or in combination with chemotherapy and/or surgery is a well-known radical treatment for head and neck cancer patients. Nevertheless acute side effects (such as moist desquamation, skin erythema, loss of taste, mucositis etc.) and in particular late toxicities (osteoradionecrosis, xerostomia, trismus, radiation caries etc.) are often debilitating and underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met in Milan with the aim of reaching a consensus on a clinical definition and management of these toxicities. The Delphi Appropriateness method was used for this consensus and external experts evaluated the conclusions. The paper contains 20 clusters of statements about the clinical definition and management of stomatological issues that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecrosis (10 clusters of statements), whereas this second part deals with trismus and xerostomia (10 clusters of statements).
