6069 Background: Locally advanced Human Papillomavirus (HPV) + oropharyngeal carcinoma (OPC) has a significantly better response, locoregional control and survival compared to non HPVOPC. Standard-dose chemoradiotherapy (sdCRT) results in significant side effects, leading to acute and life-threatening late morbidity. We studied whether reduced dose chemoradiation (rdCRT) after induction chemotherapy (IC) resulted in equivalent progression-free survival (PFS) compared to sdCRT + IC with decreased late morbidity. Methods: Patients with locally advanced OPC and < 20 pack years (py) smoking history were tested for p16 and then HPV by type-specific PCR. After 3 cycles of docetaxel, cisplatin and fluorouracil (TPF) IC all HPV+/p16+ subjects underwent clinical and radiographic evaluation. Clinical responders were randomized to either sdCRT (70Gy) or rdCRT (56Gy) with weekly carboplatin (AUC 1.5) at a 1:2 ratio. The primary endpoint was 2 year PFS; the secondary endpoint was 2 year overall survival (OS). Toxicity, late morbidity and swallowing were monitored. Results: 23 patients were enrolled and 20 randomized, 8 to sdCRT and 12 to rdCRT; 2 were HPV- and 1 refused further therapy after IC and were not randomized. Median age was 56.5 yrs (range 36-78); 30% were African-American, 10% were Hispanic, 5% were female; 16 were HPV 16+ and 4 were other high risk (HR) variants; 60% never smoked, 25% were < 10 py, and 15% were 10-20 py; 70% had high risk features: T4, N2c, or N3. Clinical response to TPF was 100%; 70% had a clinical complete response. As of February 1, patients have been followed for a median of 37.5 months (range 21.7 – 49.5). 2 year PFS/OS for sdCRT and rdCRT are 87.5% vs 83.3% (log-rank test p = 0.85), respectively. All 3 failures were local or regional and 2 of 3 occurred in non HPV16 HR variants. Conclusions: HPV+ OPC patients who received rdCRT after TPF IC had similar PFS/OS compared to those receiving sdCRT. These results uphold the potential clinical benefit of radiation dose reduction as a treatment option with comparable survival to the standard radiation dose. A Phase III trial comparing IC plus rdCRT to sdCRT alone or with IC is warranted in this population. Non-HPV16 HR variants may have a worse outcome. Clinical trial information: NCT01706939.

BackgroundRheumatic diseases in children are associated with significant morbidity and poor health-related quality of life (HRQOL). There is no health-related quality of life (HRQOL) scale available specifically for children with less common rheumatic diseases. These diseases share several features with systemic lupus erythematosus (SLE) such as their chronic episodic nature, multi-systemic involvement, and the need for immunosuppressive medications. HRQOL scale developed for pediatric SLE will likely be applicable to children with systemic inflammatory diseases.FindingsWe adapted Simple Measure of Impact of Lupus Erythematosus in Youngsters (SMILEY©) to Simple Measure of Impact of Illness in Youngsters (SMILY©-Illness) and had it reviewed by pediatric rheumatologists for its appropriateness and cultural suitability. We tested SMILY©-Illness in patients with inflammatory rheumatic diseases and then translated it into 28 languages.Nineteen children (79% female, n=15) and 17 parents participated. The mean age was 12±4 years, with median disease duration of 21 months (1-172 months). We translated SMILY©-Illness into the following 28 languages: Danish, Dutch, French (France), English (UK), German (Germany), German (Austria), German (Switzerland), Hebrew, Italian, Portuguese (Brazil), Slovene, Spanish (USA and Puerto Rico), Spanish (Spain), Spanish (Argentina), Spanish (Mexico), Spanish (Venezuela), Turkish, Afrikaans, Arabic (Saudi Arabia), Arabic (Egypt), Czech, Greek, Hindi, Hungarian, Japanese, Romanian, Serbian and Xhosa.ConclusionSMILY©-Illness is a brief, easy to administer and score HRQOL scale for children with systemic rheumatic diseases. It is suitable for use across different age groups and literacy levels. SMILY©-Illness with its available translations may be used as useful adjuncts to clinical practice and research.Electronic supplementary materialThe online version of this article (doi:10.1186/1546-0096-12-49) contains supplementary material, which is available to authorized users.
