The study objective is to assess immediate and long-term results of replacing complex defects with a free radial forearm flap in the multimodal treatment of patients with locally advanced oral cavity squamous cell carcinoma. Materials and methods. Twenty eight patients (20 women and 8 men aged 23 to 71 years) with locally advanced oral cavity squamous cell carcinoma (including 10 buccal cancers, 8 carcinomas of tongue, 6 carcinomas of the floor of the mouth, 2 retromolar area carcinomas, 1 carcinoma of the hard palate and 1 carcinoma of alveolar region of the lower jaw) underwent tumor surgery with simultaneous plastic reconstruction of the defect using radial forearm free flap at the department of head and neck tumors of N. N. Blokhin National Medical Research Center of Oncology within 2010–2018. Primary tumors were detected in 2 patients and 11 patients had residual (n = 7) or recurrent (n = 4) tumors after radiotherapy or chemoradiotherapy. Results. An overall success rate was 96.4 %. Postoperative histology revealed that there were no tumor cells at the resection edges. Postoperative complications included: complete flap necrosis in 1 patient with severe concomitant diseases, marginal flap necrosis in 2 patients (in both cases after the necrotic tissue had rejected, wounds were healed by secondary intention), sural veins thrombosis in 1 patient, acute peptic ulcer bleeding on the 6th day after surgery in 1 patient treated with emergency endoscopic hemostasis. No lethal outcomes were reported. Postoperative period lasted in average 14 days. Upon subsequent observation tumor relapse in the oral cavity occurred in 4 (14.3 %) patients, relapses of regional metastases – in 2 (7.1 %). Good aesthetic and functional results were noted. Adequate restoration of breathing, chewing, swallowing and speaking resulted in a full patients’ rehabilitation. In all cases, the radial flap adapted well to the oral cavity organs and corresponded to the surrounding tissues in thickness and consistency. Conclusion. Use of a radial forearm free flap makes it possible to successfully reconstruct extensive and complex defects after surgery of locally advanced primary and recurrent forms of oral cavity squamous cell cancer of various locations. Due to flap’s high regenerative capabilities, preoperative radiation therapy does not affect the frequency of local complications. It allows restoring vital functions of the oral cavity and achieving good aesthetic and functional results.

6040 Background: Concomitant chemoradiotherapy (CT/RT) is the standard treatment for locally advanced head and neck squamous cell carcinoma. However, late toxicity is substantial.This phase II trial explores the feasibility and efficacy of combining neoadjuvant TPF and accelerated RT where the concomitant cytostatic component is replaced with cetuximab (E), a chimeric IgG1 mAb against EGFR. Methods: Patients (pts) had previously untreated stage III/IV M0,WHO 0–1, unresectable squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx and were scheduled for 2 cycles of TPF (docetaxel 75 mg/m2 and cisplatin 75 mg/m2 day 1 and 5-FU 1,000 mg/m2 96 hours CI) every 3 weeks followed by RT (68 Gy/4.5 weeks) with E given one week before (400 mg/m2) and weekly during RT (250 mg/m2). A brachytherapy boost of 8 Gy was given to pts with oral cavity or oropharyngeal tumours. Neck dissection was planned for pts with N2–3 and complete response (CR) at the primary tumour. Tumour response was evaluated according to RECIST with CT, MRI or PET/CT after CT and at 6 weeks follow up. Toxicity (CTC 3.0) and quality of life (EORTC QLQ 30) was registered during and after treatment. Results: From 070401 to 081115 68 pts were enrolled, 56 had stage IV disease (T4, n = 14, N3, n = 9). Median age 57, 60 males, 3 oral cavity, 44 oropharynx, 10 larynx, and 11 hypopharynx. 30 pts were followed beyond 6 weeks and evaluated for response and early toxicity: stage IV disease 24 (T4, n = 6, N3, n = 3), median age 60, 25 males, 18 oropharynx, 5 larynx, and 7 hypopharynx. Remissions after TPF/after RT: CR 1/10, PR 15/18, SD 14/1, and PD 1. TPF as prescribed: 28/30 (pat refusal 1, renal insuff 1, dose reduction 0/28); E as prescribed: 22/30 (dermatitis 4, hypersensitivity 3, liver tox 1). Vital tumour in resected specimen 0/13. Alive at follow-up 29/30 (1 local failure). Conclusions: TPF followed by RT concomitant with E is feasible with manageable toxicities. Dermatitis in the irradiated neck, at least with the present accelerated fractionation, is troublesome to some patients but does not interrupt treatment and heals rapidly. To dispose of feeding tubes after disappearance of acute mucosal reactions has not been a problem. Early survival results are promising. Toxicity and survival results will be updated.

Early Progression

e17536 Background: Early progression, usually defined disease-free interval (DFI) less than six months after completing adjuvant platinum-based chemoradiotherapy (CRT), has very poor outcome for oral cavity squamous cell carcinoma (OCSCC). But there are no biomarkers to predict such early progression. Methods: Locally advanced OCSCC patients, after complete surgical resection and followed-up platinum-based adjuvant CRT, were retrospectively enrolled from Chung Shan Medical University Hospital (CSMUH, training cohort) and Taipei Veterans General Hospital (TPE-VGH, validating cohort) in Taiwan. Clinicopathologic variables of patients with DFI < or ≥ 6 months were compared by using the χ2 test. The Cox proportional hazards model was applied to identify independent factors for DFI. Survival was estimated using the Kaplan-Meier method and log-rank test. Results: A total of 350 high-risk OCSCC patients were enrolled, including 146 patients in training cohort and 204 in validating cohort. In multivariate Cox regression, pN > 0, extracapular spread, and depth of invasion ( ≥ 1cm) were independent factors for DFI in training cohort. If each factor scored one point, the scoring system could effectively predict early progression that sensitivity/specificity/area under curve (AUC) of training and validating cohort were 57.7%/91.2%/0.771 and 58.1%/83.9%/0.730, respectively (the cutoff level ≤ 2 or > 2). DFI between lower- (score 0–2) and high- (score 3) risk groups were also significantly different in both training (median DFI, 59.6 vs. 4.5 months, P < 0.001) and validating cohorts (NA vs. 9.3 months, P < 0.001). Conclusions: The established score system was effective to predict early progression after adjuvant CRT for locally advanced OCSCC.

Purpose: Although clinicians encounter patients aged ≥70 years with locally advanced oral cavity squamous cell carcinoma (LA-OCSCC), no evidence is available to facilitate decision making regarding treatment for this elderly population. Methods: We selected elderly (≥70 years) patients from the Taiwan Cancer Registry database who had received a diagnosis of LA-OCSCC. Propensity score matching was performed. Cox proportional hazards model curves were used to analyze all-cause mortality in patients in different age groups receiving different treatments. Results: The matching process yielded a final cohort of 976 patients in concurrent chemoradiotherapy (CCRT), non-treatment, radiotherapy (RT) alone, and surgery cohorts who were eligible for further analysis. After stratified analysis, the adjusted hazard ratios (aHRs) (95% confidence intervals [CIs]) derived for surgery, RT alone, and non-treatment compared with CCRT were 0.66 (0.52 to 0.83), 1.02 (0.81 to 1.28), and 1.52 (1.21 to 1.91), respectively, in patients aged 70 to 80 years. In the oldest patients (aged >80 years), multivariate analysis indicated that the results of surgery or RT alone were nonsignificant compared with those of CCRT. The aHR (95% CI) derived for the highest mortality was 1.81 (1.11 to 2.40) for non-treatment compared with CCRT. Conclusions: Surgery for elderly patients with LA-OCSCC is associated with a significant survival benefit, but the association is nonsignificant in the oldest elderly patients. No survival differences were observed between RT alone and CCRT in these elderly patients. Non-treatment should not be an option for these patients.
