PURPOSE A dose-adjusted etoposide, doxorubicin, and cyclophosphamide with vincristine and prednisone plus rituximab (DA-EPOCH-R) regimen has been shown to deliver excellent survival for adults with primary mediastinal large B-cell lymphoma (PMLBL) without the use of radiotherapy. No international prospective evaluation of this regimen has previously been reported in children and adolescents. PATIENTS AND METHODS We conducted an international single-arm phase II trial involving patients younger than age 18 years with PMLBL who were to receive six courses of DA-EPOCH-R. The primary end point was event-free survival (EFS). Overall survival and toxicity were also assessed. This trial was registered (ClinicalTrials.gov identifier: NCT01516567 ). RESULTS Analyses were based on 46 patients. The median age was 15.4 years (interquartile range: 14-16 years). The median follow-up was 59.0 months (interquartile range: 52.6-69.2 months). Fourteen events were observed (eight relapses or progressions (including three parenchymal CNS relapses), four residual lymphoma, and two second malignancies). The 4-year EFS was 69.6% (95% CI, 55.2 to 80.9), which did not differ from the rate observed historically ( P = .59). Seven deaths occurred (six disease-related and one second malignancy). The overall survival was 84.8% (95% CI, 71.8 to 92.4). Twenty-two patients (48%) reached dose levels ≥ 4. Nonhematologic adverse events grade ≥ 3 or cardiac adverse events grade ≥ 2 occurred in 47 of 276 (17%) courses and 30 of 46 patients (65%). CONCLUSION DA-EPOCH-R did not improve the EFS compared with a historical control in this first prospective multisite international study of children and adolescents with PMLBL. Further studies are required to determine the optimum therapy for children and adolescents with this lymphoma.

Purpose To investigate the effect of adding concurrent chemotherapy (CT) to cetuximab plus radiotherapy (RT; CT-cetux-RT) compared with cetuximab plus RT (cetux-RT) in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). Patients and Methods In this phase III randomized trial, patients with N0-2b, nonoperated, stage III or IV (nonmetastatic) LA-SCCHN were enrolled. Patients received once-daily RT up to 70 Gy with weekly cetuximab or with weekly cetuximab and concurrent carboplatin and fluorouracil (three cycles). To detect a hazard ratio (HR) of 0.64 for progression-free survival (PFS) with 85% power at a two-sided significance level of P = .05, 203 patients needed to be included in each arm. Results Four hundred six patients were randomly assigned to either CT-cetux-RT or cetux-RT. Patient and tumor characteristics were well balanced between arms, including p16 status. With a median follow-up of 4.4 years, the HR for PFS favored the CT-cetux-RT arm (HR, 0.73; 95% CI, 0.57 to 0.94; P = .015), with 3-year PFS rates of 52.3% and 40.5% and median PFS times of 37.9 and 22.4 months in the CT-cetux-RT and cetux-RT arms, respectively. The HR for locoregional control was 0.54 (95% CI, 0.38 to 0.76; P < .001) in favor of CT-cetux-RT. These benefits were observed regardless of p16 status for oropharynx carcinomas. Overall survival (HR, 0.80; P = .11) and distant metastases rates (HR, 1.19; P = .50) were not significantly different between the two arms. The CT-cetux-RT arm, compared with cetux-RT, had a higher incidence of grade 3 or 4 mucositis (73% v 61%, respectively; P = .014) and of hospitalizations for toxicity (42% v 22%, respectively; P < .001). Conclusion The addition of concurrent carboplatin and fluorouracil to cetux-RT improved PFS and locoregional control, with a nonsignificant gain in survival. To our knowledge, this is the first evidence of a clinical benefit for treatment intensification using cetux-RT as a backbone in LA-SCCHN.

6037 Background: Among HPV-positive Oropharyngeal Cancer (OPC) patients (pts), some has a less favorable prognosis (T4, N2/N3, smokers >10 pack-year [p/y]). We assume that neoadjuvant immunotherapy might improve their oncological outcomes, so we tested nivolumab (N) prior to ChemoRadiaTion (CRT). Methods: The study population is restricted to HPV positive OPC pts (both p16+ & HPV-DNA+) with advanced disease (T4, N2/N3) or a smoking history >10 p/y. Pts were randomly allocated 1:2 to receive either cisplatin-based CRT (n=20) or 2 cycles of N 240 mg followed by CRT (n=41). The Primary Endpoint (PE) is the rate of pts who can receive Full Treatment in Due Time (FTDT), according to these criteria: a) 2 N infusions on day 1 and on day 14-16 b) CRT started between days 28-37 after the 1st N infusion c) No RT break ≥1 week d) RT dose received >95% of theoretical dose e) Cisplatin dose received ≥200 mg/m² To achieve FTDT, all criteria are required in the Experimental Arm (EA) while only criteria c), d), and e) are required in the Control Arm (CA). In the EA, the trial was designed in 2 steps, with FTDT rate of 88% considered as inacceptable versus an alternative of 98%, a type I error of 0.10, and a type 2 error of 0.08. As per protocol, patient accrual was temporarily suspended after inclusion of 19 pts in the EA (1st step) and results were reviewed by an Independent Data Monitoring Committee (IDMC). To resume pts’ inclusion, FTDT had to be achieved in 18 pts in the EA. Results: From 07/2019 to 09/2020, 30 pts were enrolled including 11 in the CA (demographics are summarized in table). 2 pts in the EA did not reach the PE. For the 1st patient, the cisplatin dose was 2 due to grade 1 hearing loss and grade 2 tinnitus (1st cycle: 100 mg/m2, 2nd cycle: 80 mg/m2, no 3rd cycle). For the 2nd patient, CRT began at D38 due to logistical issues (maintenance of RT devices). As this delay was unrelated to N or to patient's condition, the IDMC considered that the inclusions could resume for the 2nd step. 7 N-related Adverse Events (AE) were reported in 4 pts including 3 serious AE (ankylosing spondylitis flare-up, colitis, diabetic ketoacidosis). Conclusions: Neoadjuvant N before CRT seems feasible for the treatment of OPC pts. The trial has reopened to inclusion as recommended by the IDMC. Clinical trial information: NCT03838263.

6507 Background: TPExtreme trial comparing EXTREME regimen to the taxane-based TPEx confirmed the encouraging survival results of the TPEx regimen, despite lack of significant overall survival (OS) increase, with a significantly lower toxicity than the EXTREME regimen. Herein, the QoL and exploratory analyses of survival according to 2nd line treatments focusing on immunotherapy (IO) are presented. Methods: Randomized (1:1), open-label trial. Main inclusion criteria were R/M HNSCC not suitable for loco-regional treatment, age 18-70 years, PS < 2, creatinin clearance > 60ml/min, prior cisplatin < 300 mg/m². 539 pts were enrolled over a period of 37 months (mo). QoL was evaluated with QLQ-C30 questionnaire at baseline, week(W)12, W18, W26 and analyzed by linear mixed model. The primary QoL endpoint was the Global Health Status score. 2nd line treatments were collected for 501 (93%) patients (pts), 256 in the EXTREME arm and 245 in the TPEx arm. Results: The percentage of QLQ-C30 questionnaires filled at baseline, W12, W18 and W26 were similar in the 2 arms, 89%, 52%, 43%, and 39% in the EXTREME arm and 91%, 59%, 40%, and 37% in the TPEx arm, respectively.. Higher scores of Global Health Status (p = 0.02), physical functioning (p = 0.009) and role functioning (p = 0.013) and lower scores of appetite loss (p = 0.041) were observed in the TPEx arm than in the EXTREME arm. No significant difference was observed for the other scores. In 2nd line treatment, 120 (47%) pts in the EXTREME arm and 109 (44%) in the TPEx arm received chemotherapy +/- cetuximab (CT); 41 (16%) pts in the EXTREME arm and 41 (17%) in the TPEx arm received IO, mainly anti-PD-1/PD-L1. 79% and 85% of these 2nd line treatments were given after progression in EXTREME and TPEx arms respectively. Median OS (95%CI) since randomization was 17.6 (15.2 – 19.5) mo with CT and 19.4 (13.4 – 22.3) mo with IO in the EXTREME arm vs 14.9 (13.0 – 16.3) and 21.9 (15.9 – 35.0) mo in the TPEx arm (interaction test p = 0.077) respectively. Median OS since start of 2nd line was 9.3 mo with CT and 8.3 mo with IO in the EXTREME arm, and 7.1 and 11.6 mo respectively in the TPEx arm. Conclusions: An improvement in the QoL of patients was observed in the TPEx arm compared to that of the EXTREME arm. Exploratory analysis showed that the taxane-based TPEx regimen followed by IO in 2nd line could provide interesting median OS for pts who need CT in 1st line, with less toxicity than EXTREME. This sequential treatment deserves to be compared to a strategy that starts with Platinum+5FU+pembrolizumab. Clinical trial information: NCT02268695 .

11541 Background: About 47% and 10% of HNSCC occur in pts aged ≥65 or ≥80 respectively. This population being heterogeneous, balancing efficacy with toxicity is challenging. As the G8 screening tool includes 3 nutritional items, we need to evaluate its usefulness in HNSCC pts and to establish an adapted tool for HNSCC pts. Methods: ONCOVAL is the first step of the ELAN program for pts ≥70 with HNSCC not amenable to surgery. Pts were assessed for geriatric frailties before inclusion in appropriate trials (ELAN-RT, FIT, UNFIT) depending on curative or palliative setting and fit or unfit status. The aim was to evaluate the G8 tool and EGE usable by oncologists to classify pts as fit or unfit. The EGE was elaborated by the French GERICO group for HNSCC pts, evaluating functional status, comorbidity, cognition/mood, social status. To estimate sensitivity and specificity of G8 and EGE, we used comprehensive geriatric assessment (CGA) performed by geriatricians as gold standard. Results: From 06/2013 to 08/2018, 633 pts were included in 44 centers. Data are available for 613 pts. Median age 79 years (70-97) with 45% ≥ 80. 75% males. G8 score was ≤14, i.e. at risk of geriatric frailty, in 82% pts. Assessment by EGE was done by physicians (64%), nurses (11%), ELAN staff (21%) in 20 minutes of median time. After EGE, oncologists classified 71% pts as unfit. 49% of pts were assessed by CGA. The G8 score with cut-off ≤ 14 has sensitivity 91% and specificity 30%. Lowering cut-off to 12 increased specificity to 56% but decreased sensitivity to 75%. Sensitivity of EGE was 95% and specificity 60%. Multidisciplinary interventions were more frequently implemented in pts assessed by geriatricians than in others (71% vs 47%), even after adjusting for frailty. 58% of pts included in ONCOVAL were further included in ELAN therapeutic trials. Assessment by geriatricians did not modify the rate of inclusion in trials. Conclusions: The G8 screening tool is not appropriate for HNSCC pts. The EGE was feasible and had better sensitivity and specificity. Oncologists and geriatricians must continue such collaboration to propose tailored treatments. Clinical trial information: NCT03614936.

6035 Background: Recent meta-analysis showed that immune checkpoint inhibitors (ICI) have comparable activity in younger vs older patients (pts) (≥65 years (y)). However little is known about efficacy and safety of ICI in elderly pts with relapsed/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). The aim of this study is to compare efficacy and grade ≥3 immune-related adverse events (irAEs) of ICI in pts ≥70 y with R/M SCCHN to younger pts. Methods: A retrospective study was conducted at 4 French hospitals. Eligibility criteria were pts treated with ICI for R/M SCCHN between September 2014 and December 2018. Clinical and radiological data and outcome were collected from review of medical records. Results: Two hundred twenty six pts were enrolled including 67 pts ≥ 70 y. Median age of elderly pts was 75y (range 70-87). Elderly pts received ICI as first-line treatment in 21% of pts vs 17% in younger pts. In elderly pts, 9% had ECOG of 0, 72% had ECOG of 1 and 15% had ECOG of 2 at ICI initiation vs 34%, 62% and 4% respectively in younger pts (p = 0.0006). In elderly pts, 22% had only loco-regional relapse at ICI initiation, 30% only distant recurrence and 49% had both vs 42%, 32% and 26% respectively (p = 0.0014). Elderly pts received ICI as monotherapy in 73% of pts vs 52% (p = 0.0027). The ORR in elderly pts was 23% vs 13% in younger pts (p = 0.071). After a median follow-up of 16.8 months (m) (range 10.7-23.7), median OS was 9.7m in elderly pts vs 8.7m in younger pts (p = 0.87). Median PFS was 2.7 m in elderly pts vs 1.9 m (p = 0.2). After adjustment for ECOG, type of evolution, number of ICI drugs, time between initial diagnosis and ICI start and number of previous lines, age ≥70 years was significantly associated with a better PFS (HR = 0.66 (95%CI = 0.47;0.93), p = 0.02) but was not significantly associated with OS (HR = 0.91 (95%CI = 0.61;1.34), p = 0.62). Grade ≥3 irAEs occurred in 15% of elderly pts vs 8% of younger pts (p = 0.13). Patients with grade ≥3 irAEs had a significantly higher ORR than pts without Grade ≥3 irAEs (36% vs 14%, p = 0.007). Conclusions: Elderly pts treated with ICI had significantly higher PFS but not OS after adjustment. Grade ≥3 irAEs were associated with significantly higher ORR to ICI in the whole population.

6032 Background: In the randomized phase III Study CA209141, Nivolumab (N) demonstrated significant overall survival (OS) benefit with favorable safety profile for platinum refractory R/M SCCHN and is now approved for these patients (pts). The objectives of the study are to provide additional insight into the frequency of high-grade AEs related to N and the efficacy of N in real life. Methods: Between August and December 2017, 203 pts were included in the multicenter, non-controlled phase II TOPNIVO. The main inclusion criteria were patients with platinum refractory R/M SCCHN with progressive disease, ECOG 0-2. Pts received N 3mg/kg every 2 weeks intravenously over 30 minutes. Four pts did not receive N. We report here the safety during the first 6 months (mo) after inclusion and OS results on the first 199 treated pts. Results: Median age was 62 yr, 83% were male, 84% were ECOG 0-1, 16% 2. The primary site of cancer was oral cavity 26%, oropharynx 38%, larynx 16%, hypopharynx 21%. 33% had loco regional relapse, 32% metastatic disease and 35% both. 49% had received one prior line of chemotherapy and 30% two prior lines. 157 (79%) pts ended their treatment within the first six mo: 5 for AE related to N (pneumonitis 3 pts, hepatitis 1 pt, diarrhea 1 pt), 107 for progression, 33 for death (24 related to progression, 9 to intercurrent disease), 12 other. 132 pts (66%) experienced at least 1 AE grade ≥3. On the 226 AEs grade 3-4, 21 (mainly pneumopathy, lipase increase and asthenia) were related to N and occurred in 18 pts. On the 51 AEs grade 5, 3 were considered related to N (2 pneumonitis, 1 cardiac arrest). The median OS was 7.7 mo (CI 95% [6.0; 9.5]) in the whole population; 9.2 mo [6.8; 12.1] in the 167 pts with ECOG 0-1, 3.0 mo [1.1; 6.0] in the 32 pts with ECOG 2; 12.1 mo [7.6; NR] in the 64 pts with metastatic disease, 7.7 mo [5.0; 9.6] in the 66 pts with locoregional disease and 4.6 mo [3.1; 7.9] in the 69 pts with both. OS was similar in pts older or younger 70 yr. Conclusions: The interim analysis of the TOPNIVO study shows no additional toxicities of N compared to what has been described previously, confirms the previous results of OS and provides new survival data in subgroups of pts. Clinical trial information: NCT03226756.

Purpose Adolescents (age 15 to 21 years) compared with younger children with mature B-cell non-Hodgkin's lymphoma (NHL) have been historically considered to have an inferior prognosis. We therefore analyzed the impact of age and other diagnostic factors on the risk of treatment failure in children and adolescents treated on the French-American-British Mature B-Cell Lymphoma 96 (FAB LMB 96) trial. Patients and Methods Patients were divided by risk: group A (limited), group B (intermediate), and group C (advanced), as previously described. Prognostic factors analyzed for event-free survival (EFS) included age (< 15 v ≥ 15 years), stage (I/II v III/IV), primary site, lactate dehydrogenase (LDH), bone marrow/CNS (BM/CNS) involvement, and histology (diffuse large B-cell lymphoma v mediastinal B-cell lymphoma v Burkitt lymphoma or Burkitt-like lymphoma). Results The 3-year EFS for the whole cohort was 88% ± 1%. Age was not associated as a risk factor for increased treatment failure in either univariate analysis (P = .15) or multivariate analysis (P = .58). Increased LDH (≥ 2 × upper limit of normal [ULN] v < 2 × ULN), primary site, and BM-positive/CNS-positive disease were all independent risk factors associated with a significant increase in treatment failure rate (relative risk, 2.0; P < .001, P < .012, and P < .001, respectively). Conclusion LDH level at diagnosis, mediastinal disease, and combined BM-positive/CNS-positive involvement are independent risk factors in children with mature B-cell NHL. Future studies should be developed to identify specific therapeutic strategies (immunotherapy) to overcome these risk factors and to identify the biologic basis associated with these prognostic factors in children with mature B-cell NHL.

Purpose Since our individual patient data (IPD) meta-analysis (MA) of supportive care and chemotherapy for non–small-cell lung cancer (NSCLC), published in 1995, many trials have been completed. An updated, IPD MA has been carried out to assess newer regimens and determine conclusively the effect of chemotherapy. Methods Systematic searches for randomized controlled trials (RCTs) were undertaken, followed by central collection, checking, and reanalysis of updated IPD. Results from RCTs were combined to calculate individual and pooled hazard ratios (HRs). Results Data were obtained from 2,714 patients from 16 RCTs. There were 1,293 deaths among 1,399 patients assigned supportive care and chemotherapy and 1,240 among 1,315 assigned supportive care alone. Results showed a significant benefit of chemotherapy (HR, 0.77; 95% CI, 0.71 to 0.83; P ≤ .0001), equivalent to a relative increase in survival of 23% or an absolute improvement in survival of 9% at 12 months, increasing survival from 20% to 29%. There was no clear evidence that this effect was influenced by the drugs used (P = .63) or whether they were used as single agents or in combination (P = .40). Despite changes in patient demographics, the effect of chemotherapy in recent trials did not differ from those included previously (P = .77). There was no clear evidence of a difference or trend in the relative effect of chemotherapy across patient subgroups. Conclusion This MA of chemotherapy in the supportive care setting demonstrates conclusively that chemotherapy improves overall survival in all patients with advanced NSCLC. Therefore, all patients who are fit enough and wish to receive chemotherapy should do so.

4064 Background: Prognosis of patients with peritoneal extension from gastric carcinoma remains poor. The aim of this multicentre, open-label, phase 2 randomized study was to analyze the potential survival benefit of an immediate postoperative intraperitoneal immunotherapy using a bi-specific (anti-EpCAM, anti-CD3), trifonctional agent named catumaxomab. Methods: Patients with limited synchronous carcinomatosis from gastric carcinoma (Peritoneal cancer index (PCI) ≤ 12), were treated after complete resection (gastrectomy plus all peritoneal deposits), by an intraperitoneal infusion of catumaxomab during 5 days. Patients were randomized between 2 arms according to the total doses administered of catumaxomab (100µg vs 140µg). The first end-point was the 2-year overall survival (OS). Forty randomized patients were required (20 in each arm), considering that a 2-year OS rate ≤ 30% would be considered as unacceptable, and ≥ 55%, a promising survival rate. The study was stopped prematurely due to the manufacturing stop of the catumaxomab. Results: Between March 2013 and September 2014, 26 patients were included in the study; among them, 11 were randomized, with a median PCI of 9 [1-12]. Seven patients received the whole planned treatment of catumaxomab; in the remaining 4 patients, interruptions were related to postoperative complications. One patient died postoperatively of multiorgan failure and grade 3-5 complications occurred in all the patients, without difference between the 2 groups. At the end of the follow-up, 3 were alive (25, 30, 36 months). The median OS was 19 months, and the 1 and 2- year OS rates were 63.6% and 36.4% respectively. Conclusions: This study has to be stopped prematurely; however, encouraging results regarding overall survival were observed. Intraperitoneal immunotherapy represents an innovative and promising treatment in patients with peritoneal metastases, considering the poor response to systemic chemotherapy and the “immunocompetence” of the peritoneum. The evaluation of a potential benefit of a local immunotherapy has to be pursued. Clinical trial information: NCT01784900.

6015 Background: Concomitant CT-RT is a well established standard of care (SoC) in locally advanced (LA) squamous cell carcinomas of the head and neck (SCCHN). While there is a well established dose effect relationship for RT alone in these cancers, it is not known whether this also applies to concomitant CT-RT. Methods: Patients were randomized between 75 Gy/7 weeks (Arm A) versus 70 Gy/35F in 7 weeks (Arm B). A sequential boost of 10 times 2.5 Gy after 50Gy/25F was given to the initial gross tumor volume (GTV) in Arm A. IMRT was used for arm A and 3D conformal RT for arm B. In both arms, patients (pts) received during RT 3 cycles of cisplatin at 100 mg/m2. Inclusion criteria were pts fit for receiving high dose cisplatin, non metastatic, non operated stage III-IV SCC of oral cavity, oro/hypopharynx. A 1:1 randomization was done by minimization on centers, N & T stages & GTV uni/bilateral. To detect a hazard ratio (HR) of 0.56 in locoregional (LR) control, inclusion of 310 pts was required to observe 109 LR progressions and achieve 85% power at 2-sided significance level of 0.05. Results: Between 2005 and 2015, 188 pts were randomized: 82% males, median age 58 years, 85% oropharynx. The accrual rate was slower than expected, due to the fact that IMRT became a SoC and was only allowed in arm A. As a consequence the trial was discontinued after inclusion of 188 patients. The majority of pts had stage IVa (73% vs 72%). All initial characteristics were well balanced between arms. The median follow-up was 4.7 years, not different between arms. Acute and late xerostomia were markedly improved in arm A (IMRT arm). The 1-year grade 0-1 salivary toxicity (RTOG) was 81% and 34% (p< 0.0001) in arm A and B respectively. At 3 years these rates were 92% vs 53% (p=0.0003). The increase of the dose to the GTV with IMRT did not transfer in a higher LR control probability with an adjusted HR of 0.88 [95%CI 0.51-1.52] (p=0.63). PFS, overall survival were not significantly different between the 2 arms. Conclusions: The dose escalation of RT to the GTV did not improve LR control in patients treated with concomitant CT-RT. This trial adds some new evidence level 1 in favor of IMRT in LA SCCHN. Clinical trial information: NCT00158678.

e17535 Background: HPV-driven oropharyngeal cancer (OPC) patients are characterized by a better prognosis than their HPV-negative counterparts. However, this significant survival advantage is not homogeneous and studies have highlighted that among HPV-positive patients those with a smoking history have a significantly increased risk of disease progression and death compared to those who have never smoked. The reason why tobacco consumption impacts negatively the prognosis is still elusive. Tobacco might induce additional genetic alterations leading to a more aggressive phenotype. The purpose of this study is to characterize the mutational profile of HPV-positive OPC by smoking status. We hypothesize a higher frequency of mutations affecting among smokers. Methods: Targeted next-generation sequencing of 38 oncogenes/tumor suppressor genes that are commonly mutated in cancers caused by tobacco/alcohol consumption was performed in 62 HPV-driven OPC cases stratified by smoking status. Results: The study population included 37 (60%) non-smokers and 25 (40%) smokers distributed as follows: 1 (4%) patient smoked 20 PY. Twenty (31%) patients had no mutation, 14 (23%) had 1 mutation and 28 (46%) had 2 or more mutations. The most commonly mutated genes regardless of tobacco consumption were PIK3CA (20%), MLL2 (20%), TP53 (8%), FAT 1 (15%), FBXW7 (16%), NOTCH 1 (9%) and FGFR3 (9%). Mutation rate was not significantly different in smokers compared to non-smokers even when analyses focused on heavy smokers (>20 pack-years compared to

6003Background: Chemo-radiotherapy (CT/RT) and cetuximab-RT (cetux-RT) were established as standard treatments in non-operated locally advanced (LA) SCCHN. While the addition of cetux to cisplatin/RT offers no benefit as compared to the same CT/RT alone (RTOG 0522 trial), it was not known whether the addition of carboplatin/5FU to cetux-RT would improve outcome, as compared to cetux-RT alone. Methods: The GORTEC 2007-01 trial was restricted to patients (pts) with no or limited nodal spread (N0-N2a) and was run in parallel with GORTEC 2007-02 trial testing induction vs concurrent CT in N2b/c-N3 pts. Inclusion criteria were pts fit for receiving CT, non-metastatic, non-operated stage III-IV SCC of oral cavity, oro/hypopharynx and larynx. The 1:1 randomization between cetux-RT (arm A) and cetux-CT/RT (arm B) was done by minimization on centers, N and T stages. Cetux was given as a loading dose of 400 mg/m2 followed by weekly 250 mg/m2 during RT. RT total dose was 70 Gy (2 Gy/day, 5 days/week). Concurrent CT ...

TPS6099 Background: 30% of SCCHN occur in patients (pts) >= 70y and the main challenges in these pts are to cope with the treatment benefit/risk ratio and the tumor related symptoms. However, these pts are usually not included in trials. We developed a large prospective clinical program planed to enroll 448 pts in 3 distinct trials to improve the multidisciplinary management of elderly SCCHN pts. The main objectives of this study are to demonstrate that a geriatric evaluation is feasible in daily practice for SCCHN pts and to set new standards of care in this population. Methods: To be included in one of the three trials, SCCHN pts aged 70 or over, not suitable for surgery, must first be enrolled in ELAN-ONCOVAL study where they are classified as fit or unfit, using a geriatric evaluation applicable to the daily practice. Comprehensive Geriatric Assessment is optional. In curative situation, unfit pts are proposed to be enrolled in the randomized non-inferiority ELAN-RT trial, comparing standard radiother...

10032 Background: We recently reported the results in C & A with low risk (group A), intermediate risk (group B) and high risk (group C) mature B-NHL treated on FAB/LMB 96 (Gerrard et al, Br J Haematol, 2008; Patte et al, Blood, 2007; Cairo et al, Blood, 2007, respectively). Adolescent age (15–21 yrs) has historically been considered to be an independent risk factor for poor outcome in subsets of mature B-NHL (Hochberg/Cairo et al, Br J Haematol, 2008; Burkhardt et al, Br J Haematol 2005; Cairo et al, Br J Haematol, 2003). Methods: We analyzed the EFS of all pts treated on FAB/LMB 96 and the following risk factors were significant in a univariate and Cox multivariate analysis: age ( No significant financial relationships to disclose.

e20638 Background: Anticancer therapies are associated with various and multiple cutaneous side effects frequently impacting patients’ quality of life and sometimes impairing treatment continuation. Some new skin syndromes and their potential relationship with drug efficacy have been the subject of hundreds of publications over the last few years. Methods: All physicians in our institution were informed by mail about the creation of a weekly consultation and the availability of an emergency call number specifically devoted to the management of adverse cutaneous reactions to anticancer agents. Patients could be referred to us from our institute or from other french institutes. All cutaneous side effects were recorded. Type, severity, and duration of symptoms were described. Imputability of the drugs was evaluated according to semiological, chronological and bibliographical criteria. Results: Over a 4 months period, 215 visits have been performed for a total of 128 patients. 169 events were reported among which 123 were considered to be imputable to the drugs. Several new cutaneous side effects were identified. Hiring a beautician and a pedicure for aesthetic complaints or hand foot skin reactions has been necessary in several cases. Causative agents were mostly targeted therapies (76.4%). Topical (n=132) or systemic treatments (n=45) were prescribed. Temporary dose reduction or treatment interruption was recommended in 18 cases (10.6%). This pilot experience was highly appreciated by both patients and physicians. It was consolidated as a permanent organization at the frontier between oncology and dermatology with the creation of an adapted case report form (CRF). Conclusions: There is a real need for dermatological management of skin side effects in a cancer institute, especially if early trials testing new agents are performed. Dedicated collaboration between oncologists and dermatologists should be promoted as well as the creation of a global skin-oriented CRF in order to facilitate international collaborations and to evaluate the impact of this dermatological management on compliance to treatment.
