Predictive factors for mandibular osteoradionecrosis after irradiation of head and neck cancers

Cancer Radiother. 2021 Apr 6:S1278-3218(21)00049-4. doi: 10.1016/j.canrad.2021.03.002. Online ahead of print.ABSTRACTThe identification of the different risk factors for mandibular osteoradionecrosis (ORN) must be done before and after the management of patients with head and neck cancer. Various clinical criteria for this severe radiation-induced complication are related to the patient (intrinsic radiosensitivity, malnutrition associated with thin weight loss, active smoking intoxication, microcapillary involvement, precarious oral status, hyposalivation) and/or related to the disease (oral cavity, large tumor size, tumor mandibular invasion). Therapeutic risk factors are also associated with a higher risk of ORN (primary tumor surgery, concomitant radio-chemotherapy, post-irradiation dental avulsion, preventive non-observance with the absence of stomatological follow-up and daily installation of gutters fluoride and, non-observance curative healing treatments). Finally, various dosimetric studies have specified the parameters in order to target the dose values distributed in the mandible, which increases the risk of ORN. An mean mandibular dose greater than 48-54Gy and high percentages of mandibular volume receiving 40 to 60Gy appear to be discriminating in the risk of developing an ORN.PMID:33836955 | DOI:10.1016/j.canrad.2021.03.002

Abstract Head and neck cancer (HNC), which includes epithelial malignancies of the upper aerodigestive tract (oral cavity, oropharynx, pharynx, hypopharynx, larynx, and thyroid), are slowly but consistently increasing, while the overall survival rate remains unsatisfactory. Because of the multifunctional anatomical intricacies of the head and neck, disease progression and therapy-related side effects often severely affect the patient's appearance and self-image, as well as their ability to breathe, speak, and swallow. Patients with HNC require a multidisciplinary approach involving surgery, radiation therapy, and ...

CONCLUSION: Analysis by logistic regression determined there is significant weight loss (>10%) in patients receiving radical RT as compared with adjuvant RT. Better outcomes were observed in patients receiving RT by IMRT-IGRT technique as compared with 3DCRT technique. PMID: 32329543 [PubMed - as supplied by publisher]

Madam — Since the publication of the EXTREME trial [1], cisplatin/carboplatin, 5-fluorouracil (5-FU) and cetuximab has become the standard of care as first-line palliative chemotherapy for recurrent/metastatic head and neck carcinoma (HNC) [2,3]. However, in England, cetuximab in HNC was only available through the Cancer Drugs Fund [2]. In August 2017, the National Institute for Health and Care Excellence (NICE) withdrew cetuximab from use in combination with platinum-based chemotherapy in all non-oral cavity recurrent/metastatic HNC [4].

Lorenzo Lo Muzio Head and neck squamous cell carcinoma (HNSCC) is one of the main neoformations of the head–neck region and is characterized by the presence of squamous carcinomatous cells of the multi-layered epithelium lining the oral cavity, larynx, and pharynx. The annual incidence of squamous cell carcinoma of the head and neck (HNSCC) comprises approximately 600,000 new cases globally. Currently, the 5-year survival from HNSCC is less than 50%. Surgical, radiotherapy, and chemotherapy treatments strongly compromise patient quality of life. MicroRNAs (miRNAs) are a family of small noncoding endogenous...
