Treating Acute Cervical Radiodermatitis with Photobiomodulation Therapy: A Report of Two Cases.

The objective of this study was to report the application of photobiomodulation therapy (PBMT) in the treatment of two patients diagnosed with acute cervical radiodermatitis (RD) induced by radiotherapy. An undesirable effect of radiotherapy, RD often poses a limitation to the continuity of treatment that can negatively affect the control and prognosis of the disease. RD is frequently associated with pain and aesthetic impairment and can significantly influence quality of life.

Intraoral stents in preventing adverse radiotherapeutic effects in lip cancer patients.

Aim: To fabricate and evaluate the efficacy of individualized intraoral stents to minimize the potential side effects of radiation on oral tissues in patients with early stages of lip cancer.

Background: Lower lip cancer is a common tumor found almost exclusively in middle-aged and elderly males. Surgery is the most common treatment of choice, although for less extensive lesions, exclusive radiotherapy may be preferred.

DNA repair gene excision repair cross complementing-group 1 (ERCC1) in head and neck squamous cell carcinoma: analysis of methylation and polymorphism (G19007A), protein expression and association with epidemiological and clinicopathological factors.

Aims: To evaluate the associations of excision repair cross complementing-group 1 (ERCC1) (DNA repair protein) (G19007A) polymorphism, methylation and immunohistochemical expression with epidemiological and clinicopathological factors and with overall survival in head and neck squamous cell carcinoma (HNSCC) patients.

Methods And Results: The study group comprised 84 patients with HNSCC who underwent surgery and adjuvant radiotherapy without chemotherapy. Bivariate and multivariate analyses were used.
