Influence of age and self-stigmatization on social eating and drinking issues in French outpatients living with and beyond head and neck cancer: a mixed-method study.

PURPOSE: Social eating (SE) is a corner stone of daily living activities, quality of life (QoL), and aging well. In addition to feeding functional disorders, patients with head and neck cancer (HNC) face individual and social psychological distress. In this aging population, we intended to better assess the influence of age on these challenges, and the role of self-stigmatization limiting SE in patients with and beyond HNC. METHODS: This was an exploratory multicenter cross-sectional mixed method study. Eligibility criteria were adults diagnosed with various non-metastatic HNC, before, during, or until 5 years after treatment. SE disorders were explored with the Performance Status Scale Public Eating rate (PSS-HN PE). In the quantitative part of the study, SE habits, Functional Assessment of Cancer Therapy Body Image Scale (FACT-MBIS) and specific to HNC (FACT-HN35) were also filled in by the patients. In the qualitative study, the semi-structured interview guide was drawn out to explore stigma, especially different dimensions of self-stigmatization. RESULTS: A total of 112 patients were included, mean age 64.7 years, 23.2% of female. One-third (n = 35) of patients had an abnormal PSS-HN PE rate < 100. Younger patients had more often an impaired Normalcy of Diet mean (70.4 vs 82.7, p = .0498) and PE rates (76 vs 86.9, p = .0622), but there was no difference between age subgroups in MBIS nor FACT-HN scores. Seventy patients (72.2%) found SE and drinking « important¼ to « extremely important¼ in their daily life. The qualitative study reported self-stigmatization in two older patients and strategies they have developed to cope with in their behaviors of SE. CONCLUSION: This study confirms that SE remains of high concern in patients with and beyond HNC. Even in older patients experiencing less often functional feeding disorders, body image changes and SE issues are as impaired as in younger patients and need to be addressed.

Cost-effectiveness of weekly adaptive radiotherapy versus standard IMRT in head and neck cancer alongside the ARTIX trial.

BACKGROUND AND PURPOSE: We performed a cost-effectiveness analysis (CEA) comparing an adaptive radiotherapy (ART) strategy, based on weekly replanning, aiming to correct the parotid gland overdose during treatment and expecting therefore to decrease xerostomia, when compared to a standard IMRT. MATERIALS AND METHODS: We conducted the ARTIX trial, a randomized, parallel-group, multicentric study comparing a systematic weekly replanning ART to a standard IMRT. The primary endpoint was the frequency of xerostomia at 12 months, measured by stimulating salivary flow with paraffin. The CEA was designed alongside the ARTIX trial which was linked to the French national health data system (SNDS). For each patient, healthcare consumptions and costs were provided by the SNDS. The reference case analysis was based on the primary endpoint of the trial. Sensitivity and scenario analyses were performed. RESULTS: Of the 129 patients randomly assigned between 2013 and 2018, only 2 records were not linked to the SNDS, which provides a linkage proportion of 98.4%. All of the other 127 records were linked with good to very good robustness. On the intent-to-treat population at 12 months, mean total costs per patient were €41,564 (SD 23,624) and €33,063 (SD 16,886) for ART and standard IMRT arms, respectively (p = 0.033). Incremental cost effectiveness ratio (ICER) was €162,444 per xerostomia avoided. At 24 months, ICER was €194,521 per xerostomia avoided. For both progression-free and overall survival, ART was dominated by standard IMRT. CONCLUSION: The ART strategy was deemed to be not cost-effective compared with standard IMRT for patients with locally advanced oropharyngeal cancer.

Head and neck cancer patients under radiotherapy undergoing skin application of hydrogel dressing or hyaluronic acid: results from a prospective, randomized study.

PURPOSE: Acute radiodermatitis (ARD) is a frequent side effect of radiotherapy, a therapeutic option for head and neck squamous cell carcinoma (HNSCC). It is responsible for pain, quality of life (QoL) impairment, and increased risk of treatment discontinuation, which may compromise the prognosis for patients. Local therapies to prevent or alleviate ARD have been proposed without providing any high level of evidence to establish recommendations. METHODS: We implemented a prospective multicenter randomized study on patients with HNSCC treated with definitive radiotherapy to assess the impact on ear, nose, and throat (ENT) pain of the application of a hydrogel-based skin dressing (HydroTac®) compared with the application of hyaluronic acid (Ialuset®) during radiotherapy. RESULTS: Out of 130 enrolled patients, 48 patients per group were assessable for the main endpoint. No difference between groups was found: a worsening of ENT pain of 3 points or more on a visual analog scale from the initiation to 1 month after the end of the radiotherapy was observed for 8 patients (16.7%) who received HydroTac® compared to 13 patients (27%) who received Ialuset® (p = 0.342). The proportion of patients who experienced ARD and grades of ARD (CTCAE v4.0 criteria) were similar between groups. Patient compliance with radiodermatitis treatment was poor, with 56.1% of patients in the HydroTac® group having their treatment temporarily stopped. CONCLUSION: The application of a hydrogel dressing to prevent ARD during radiotherapy for HNSCC patients has failed to demonstrate a benefit. These results may be limited by the difficulties of applying the dressing.

Weekly Adaptive Radiotherapy vs Standard Intensity-Modulated Radiotherapy for Improving Salivary Function in Patients With Head and Neck Cancer: A Phase 3 Randomized Clinical Trial.

Importance: Xerostomia is a major toxic effect associated with intensity-modulated radiotherapy (IMRT) for oropharyngeal cancers. Objective: To assess whether adaptive radiotherapy (ART) improves salivary function compared with IMRT in patients with head and neck cancer. Design, Setting, and Participants: This phase 3 randomized clinical trial was conducted in 11 French centers. Patients aged 18 to 75 years with stage III-IVB squamous cell oropharyngeal cancer treated with chemoradiotherapy were enrolled between July 5, 2013, and October 1, 2018. Data were analyzed from November 2021 to May 2022. Interventions: The patients were randomly assigned (1:1) to receive standard IMRT (without replanning) or ART (systematic weekly replanning). Main Outcomes and Measures: The primary end point was the frequency of xerostomia, measured by stimulating salivary flow with paraffin. Secondary end points included salivary gland excretory function measured using technetium-99m pertechnetate scintigraphy, patient-reported outcomes (Eisbruch xerostomia-specific questionnaire and the MD Anderson Symptom Inventory for Head and Neck Cancer questionnaire), early and late toxic effects, disease control, and overall and cancer-specific survival. Results: A total of 132 patients were randomized, and after 1 exclusion in the ART arm, 131 were analyzed: 66 in the ART arm (mean [SD] age at inclusion, 60 [8] years; 57 [86.4%] male) and 65 in the standard IMRT arm (mean [SD] age at inclusion, 60 [8] years; 57 [87.7%] male). The median follow-up was 26.4 months (IQR, 1.2-31.3 months). The mean (SD) salivary flow (paraffin) at 12 months was 630 (450) mg/min in the ART arm and 584 (464) mg/min in the standard arm (P = .64). The mean (SD) excretory function of the parotid gland at 12 months, measured by scintigraphy, improved in the ART arm (48% [17%]) compared with the standard arm (41% [17%]) (P = .02). The 2-year-overall survival was 76.9% (95% CI, 64.7%-85.4%) in both arms. Conclusions and Relevance: This randomized clinical trial did not demonstrate a benefit of ART in decreasing xerostomia compared with standard IMRT. No significant differences were found in secondary end points except for parotid gland excretory function, as assessed by scintigraphy, or in survival rates.

[Ten years of advances in head and neck surgery, how does this influence postoperative radiotherapy?] / Dix ans de progrès en chirurgie des tumeurs de la tête et du cou, quel impact sur la radiothérapie postopératoire ?

Minimal invasive surgery and reconstructive surgery tend to become the standard in France in the management of head and neck tumors. The use of endoscopic approaches (through endoscopic endonasal/transoral approaches±robot-assisted) instead of open surgery and the use of reconstructive surgery using autologous (flaps) or heterologous materials aim to reduce surgical morbidity by making-up for the loss of substance to restore the function. The impact of these substantial changes in surgical techniques has not been assessed with respect to postoperative radiotherapy practice. Endoscopic endonasal approaches result, however, in piecemeal resection, which, along the analysis of resection margins (a key prognostic factor), make the interpretation of the quality of resection more complex for radiation oncologists. The definition of tumour sub-volumes to be irradiated and doses to these sub-volumes then requires accurate histosurgical mapping and close multidisciplinary consultation between surgeons, pathologists, radiologists and radiation oncologists. Similarly, the increasing use of various types of flaps (of soft tissue or bone flaps), adapted to the patient and tumor anatomy, is associated with substantial modifications to the operating bed. The delineation of tumour volumes in postoperative radiotherapy is made more complex. Tremendous multidisciplinary efforts should now be initiated to fully take advantage of surgical advances and to further optimize the therapeutic index by making radiotherapy also less toxic, i.e. "mini-morbid".

[Systemic treatments of metastatic or locally recurrent adenoid cystic carcinoma of the head and neck, a systematic review]. / Traitements systémiques du carcinome adénoïde kystique de la sphère ORL localement avancé ou métastatique, une revue systématique.

INTRODUCTION: Adenoid Cystic Carcinoma is a rare tumor of the head and neck sphere. The purpose of this review is a state of the art of systemic treatments (chemotherapies, targeted therapies, immunotherapies) for locally recurrent or metastatic disease. MATERIAL AND METHODS: Our inclusion criteria included head and neck adult patient, metastatic or locally advanced, treated by a systemic therapy, and with at least 10 or more patients. RESULTS: Forty articles have been selected in this review. The objective response rate under chemotherapy was predominantly<10% (0-70%) with objective responses in monotherapy with cisplatin, mitoxantrone, vinorelbine and eribuline, and with cisplatin-vinorelbine combination. EGFR inhibitors provided 40% objective responses only in combination. Inhibitors of VEGF and histone deacetylase have allowed disease stabilization in progressive patients, with about 10% of objective response. Inhibitors of c-KIT monotherapy yield objective response rates of<5%. Direct inhibitors of the PI3K/AKT/mTOR pathway display 0% objective response rate. CONCLUSION: The best objective response rates were obtained with cisplatin-vinorelbine combination. Many targetable molecular abnormalities have been identified and studies have shown prolonged stabilization with EGFR, VEGF and HDAC inhibitors. Multi-disciplinary collaborative consultation (MCC) meetings such as French network of experts in rare head and neck tumors (REFCOR) or Molecular MCC should be proposed and may allow referral to centers proposing specific therapeutic trials.

Induction Chemotherapy Followed by Cetuximab Radiotherapy Is Not Superior to Concurrent Chemoradiotherapy for Head and Neck Carcinomas: Results of the GORTEC 2007-02 Phase III Randomized Trial.

PURPOSE: Both concurrent chemoradiotherapy (CT-RT) and cetuximab radiotherapy (cetux-RT) have been established as the standard of care for the treatment of locally advanced squamous cell carcinoma of the head and neck. It was not known whether the addition of induction chemotherapy before cetux-RT could improve outcomes compared with standard of care CT-RT. PATIENTS AND METHODS: The current trial was restricted to patients with nonmetastatic N2b, N2c, or N3 squamous cell carcinoma of the head and neck and fit for taxotere, cisplatin, fluorouracil (TPF). Patients were randomly assigned to receive three cycles of TPF followed by cetux-RT versus concurrent carboplatin fluorouracil and RT as recommended in National Comprehensive Cancer Network guidelines. The trial was powered to detect a hazard ratio (HR) of 0.66 in favor of TPF plus cetux-RT for progression-free survival at 2 years. The inclusion of 180 patients per arm was needed to achieve 80% power at a two-sided significance level of .05. RESULTS: Between 2009 and 2013, 370 patients were included. All patients and tumors characteristics were well balanced between arms. There were more cases of grade 3 and 4 neutropenia in the induction arm, and the induction TPF was associated with 6.6% treatment-related deaths. With a median follow-up of 2.8 years, 2-year progression-free survival was not different between both arms (CT-RT, 0.38 v TPF + cetux-RT, 0.36; HR, 0.93 [95% CI, 0.73 to 1.20]; P = .58). HR was 0.98 (95% CI, 0.74 to 1.3; P = .90) for locoregional control and 1.12 (95% CI, 0.86 to 1.46; P = .39) for overall survival. These effects were observed regardless of p16 status. The rate of distant metastases was lower in the TPF arm (HR, 0.54 [95% CI, 0.30 to 0.99]; P = .05). CONCLUSION: Induction TPF followed by cetux-RT did not improve outcomes compared with CT-RT in a population of patients with advanced cervical lymphadenopathy.

Improved Outcome by Adding Concurrent Chemotherapy to Cetuximab and Radiotherapy for Locally Advanced Head and Neck Carcinomas: Results of the GORTEC 2007-01 Phase III Randomized Trial.

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.

Randomized trial comparing two methods of re-irradiation after salvage surgery in head and neck squamous cell carcinoma: Once daily split-course radiotherapy with concomitant chemotherapy or twice daily radiotherapy with cetuximab.

BACKGROUND: A previous randomized trial in recurrent Head and Neck squamous-cell carcinoma (HNSCC) has shown re-irradiation combined with chemotherapy after salvage surgery significantly improved disease-free survival (DFS). The objective of this randomized trial was to compare two methods of re-irradiation in terms of toxicity and survival. PATIENTS AND METHODS: Patients with recurrence/second primary in previously irradiated area were randomly allocated to receive either 60 Gy over 11 weeks with concomitant 5FU - hydroxyurea (VP-arm), or 60 Gy (1.2 Gy twice daily) over 5 weeks with cetuximab (HFR-arm). Primary endpoint was treatment interruption >15 days (acute toxicity). RESULTS: Twenty-six patients were included in VP-arm and 27 in HFR-arm. One patient in VP-arm experienced >15 days interruption due to toxicity, and none in HFR-arm. In both arms, all patients received at least 60 Gy. In VP-arm, 8/26 patients had chemotherapy delay and/or dose reduction. In HFR-arm, 4/27 patients had <6 cycles cetuximab. There was no significant difference in overall survival (Median OS: 37.4 months vs 21.9 months, p = 0.12). Toxicities and DFS were not different between 2 arms. CONCLUSIONS: Twice daily schedule of re-irradiation of 60 Gy/5 weeks with cetuximab was tolerable and no significant difference in treatment delays occurred between two arms.

Approach to oligometastatic disease in head and neck cancer, on behalf of the GORTEC.

Median survival for recurrent/metastatic head and neck squamous cell cancer (HNSCC) patients is about 10 months after first-line best systemic treatment. We aimed to assess current approaches of oligometastatic HNSCC patients by the analysis of current concept and published data (1995-2017) in this population. Five-year survival rates are over 20% in selected patients who undergo metastasis-directed therapy by either surgery or stereotactic irradiation. Human papillomavirus(+) HNSCC patients have more disseminated metastases but respond more favorably and also benefit from ablative treatments. Treatments of oligometastases are expanding rapidly. Unmet needs include revised imaging follow-up strategies to detect metastases earlier, identification of predictive noninvasive biomarkers for treatment guidance, assessment and corrections of biases in current studies and randomized clinical trials.

Very accelerated radiotherapy or concurrent chemoradiotherapy for N3 head and neck squamous cell carcinoma: Pooled analysis of two GORTEC randomized trials.

OBJECTIVE: To analyze the outcome of N3 patients treated with very accelerated radiotherapy (VART) or different schedules of concurrent chemoradiotherapy (CRT) within two phase III trials. PATIENTS AND METHODS: Data of 179 patients with N3 HNSCC from two GORTEC randomized trials (96-01 and 99-02) were pooled. Patients received either VART: 64.8Gy/3.5weeks or one of the 3 following CRT regimens: Conventional CRT: 70Gy/7weeks+3 cycles carboplatin-5FU; Moderately accelerated CRT: 70Gy/6weeks+2 cycles carboplatin-5FU; Strongly intensified CRT: 64Gy/5weeks+cisplatin (days 2, 16, 30) and 5 FU (days 1-5, 29-33) followed by 2 cycles adjuvant cisplatin-5FU. RESULTS: Median follow-up was 13.3 and 5.2years for GORTEC 96-01 and GORTEC 99-02, respectively. Five-year overall survival (OS) was 13.8%. No significant difference was observed between CRT versus VART in terms of OS (hazard ratio [HR]: 0.93, p=0.68), loco-regional progression (HR: 0.70, p=0.13), or distant progression (HR: 0.86, p=0.53). OS was worse for patients with T3-4 tumors versus early T stage (11.0% versus 25.7%, p=0.015). In multivariate analysis, the oropharyngeal subsite presented a higher risk of distant metastasis (as first event 46.5% vs 19.2%, p<0.001),). A significant interaction between treatment modalities and subsites has been observed concerning loco-regional and distant failures. CONCLUSION: The outcome of N3 HNSCC was extremely poor despite treatment intensification and no difference between CRT and VART. Both distant metastases and loco-regional failures remain important treatment challenge.

Retrospective evaluation of concomitant cetuximab and radiotherapy tolerance for locoregional advanced head and neck squamous cell carcinoma treatment in patients unfit for platinum-based chemotherapy.

Radiotherapy associated with cetuximab (Cet-RT) is an alternative treatment to platinum-based chemoradiotherapy in locally advanced head and neck carcinoma (LAHNC). Reviews suggest that the use of cetuximab is associated with poorer tolerance in patients unfit for chemotherapy than in pivotal trial. We retrospectively studied patients first treated by Cet-RT for LAHNC presenting contraindications to chemoradiotherapy. Objectives were treated population description, acute tolerance, progression-free survival (PFS), overall survival (OS), and 3-month clinical response. Eighty-eight patients were included. Treatment was completed without delay for 43 patients. Grade 3-4 acute toxicity was described in 44.3%: mucositis (n = 20), radiodermatitis (n = 25) folliculitis (n = 10), and anaphylaxis (n = 6). Fourteen patients died during treatment. Median PFS and OS were 6.3 and 18.7 months, respectively. We confirm that Cet-RT tolerance in unfit patients is poorer than that in trials. Survival data illustrate patients' frailty and suggest that balanced use of Cet-RT is required in this population.

Intensive nutritional care for patients treated with radiotherapy in head and neck cancer: a randomized study and meta-analysis.

Nutritional care improves quality of life (QOL) in head and neck cancer patients treated with radiotherapy. The aim of our study was to determine whether intensive nutritional care (INC) would further improve QOL. In addition to a control group based on European and American guidelines, patients included in the INC group received six meetings with a dietitian. QOL was measured after radiotherapy using the EORTC QLQ-C30. We performed a meta-analysis to determine the best nutritional care. In the 87 patients, the QOL scores, weight, energy, and protein intakes were similar between the INC group (n = 43) and the control group (n = 44). The meta-analysis revealed no heterogeneity and significant differences in QOL (three studies) (p = 0.46) or weight changes after radiotherapy (four studies) (p = 0.06). The nutritional care specified in the European and American guidelines is composed of well-defined recommendations, and appears sufficient to maintain QOL without further intervention.

[Oropharyngeal cancer]. / Cancer de l'oropharynx.

Oropharyngeal carcinomas, contrary to other head and neck carcinomas are of increasing frequency, mostly due to a frequent association with human papillomavirus infection. Pluridisciplinary management is necessary. New techniques as transoral surgery or intensity-modulated radiation therapy have the potential to reduce toxicities and morbidity while offering equivalent local control rates. Early stages may be treated with single modality treatment (surgery or radiotherapy) with five-year overall survival rate exceeding 80%. Advanced stages need therapeutic associations and five-years survival rates are inferior to 40%.

Concomitant chemoradiotherapy versus acceleration of radiotherapy with or without concomitant chemotherapy in locally advanced head and neck carcinoma (GORTEC 99-02): an open-label phase 3 randomised trial.

BACKGROUND: Concomitant chemoradiotherapy and accelerated radiotherapy independently improve outcomes for patients with locally advanced head and neck squamous-cell carcinoma (HNSCC). We aimed to assess the efficacy and safety of a combination of these approaches. METHODS: In our open-label phase 3 randomised trial, we enrolled patients with locally advanced, stage III and IV (non-metastatic) HNSCC and an Eastern Cooperative Oncology Group performance status of 0-2. We randomly allocated patients centrally with a computer program (with centre, T stage, N stage, and localisation as minimisation factors) in a 1:1:1 ratio to receive conventional chemoradiotherapy (70 Gy in 7 weeks plus three cycles of 4 days' concomitant carboplatin-fluorouracil), accelerated radiotherapy-chemotherapy (70 Gy in 6 weeks plus two cycles of 5 days' concomitant carboplatin-fluorouracil), or very accelerated radiotherapy alone (64·8 Gy [1·8 Gy twice daily] in 3·5 weeks). The primary endpoint, progression-free survival (PFS), was assessed in all enrolled patients. This trial is completed. The trial is registered with ClinicalTrials.gov, number NCT00828386. FINDINGS: Between Feb 29, 2000, and May 9, 2007, we randomly allocated 279 patients to receive conventional chemoradiotherapy, 280 to accelerated radiotherapy-chemotherapy, and 281 to very accelerated radiotherapy. Median follow-up was 5·2 years (IQR 4·9-6·2); rates of chemotherapy and radiotherapy compliance were good in all groups. Accelerated radiotherapy-chemotherapy offered no PFS benefit compared with conventional chemoradiotherapy (HR 1·02, 95% CI 0·84-1·23; p=0·88) or very accelerated radiotherapy (0·83, 0·69-1·01; p=0·060); conventional chemoradiotherapy improved PFS compared with very accelerated radiotherapy (0·82, 0·67-0·99; p=0·041). 3-year PFS was 37·6% (95% CI 32·1-43·4) after conventional chemoradiotherapy, 34·1% (28·7-39·8) after accelerated radiotherapy-chemotherapy, and 32·2% (27·0-37·9) after very accelerated radiotherapy. More patients in the very accelerated radiotherapy group had RTOG grade 3-4 acute mucosal toxicity (226 [84%] of 268 patients) compared with accelerated radiotherapy-chemotherapy (205 [76%] of 271 patients) or conventional chemoradiotherapy (180 [69%] of 262; p=0·0001). 158 (60%) of 265 patients in the conventional chemoradiotherapy group, 176 (64%) of 276 patients in the accelerated radiotherapy-chemotherapy group, and 190 (70%) of 272 patients in the very accelerated radiotherapy group were intubated with feeding tubes during treatment (p=0·045). INTERPRETATION: Chemotherapy has a substantial treatment effect given concomitantly with radiotherapy and acceleration of radiotherapy cannot compensate for the absence of chemotherapy. We noted the most favourable outcomes for conventional chemoradiotherapy, suggesting that acceleration of radiotherapy is probably not beneficial in concomitant chemoradiotherapy schedules.

Randomized trial of postoperative reirradiation combined with chemotherapy after salvage surgery compared with salvage surgery alone in head and neck carcinoma.

PURPOSE: Full-dose reirradiation combined with chemotherapy has been shown to be feasible after salvage surgery with acceptable toxicity. The Groupe d'Etude des Tumeurs de la Tête et du Cou and Groupe d'Oncologie Radiothérapie Tête Et Cou groups performed a randomized study to assess its efficacy. PATIENTS AND METHODS: Between 1999 and 2005, 130 patients with head and neck cancer were treated with salvage surgery and randomly assigned to full-dose reirradiation combined with chemotherapy (RT arm) or to observation (a "wait and see" approach; WS arm). Eligibility criteria were recurrence or a second primary tumor in a previously irradiated area, no major sequelae resulting from the first radiotherapy, good general condition, no distant metastasis, and salvage surgery with macroscopic complete resection. Patients in the RT arm received 60 Gy over 11 weeks combined with concomitant fluorouracil and hydroxyurea. RESULTS: Sixty-five patients were randomly assigned to each arm. There was no imbalance in the distribution of the main tumor and patients characteristics. The most serious acute toxicity in the RT arm was mucositis, attaining grade 3 or 4 in 28% of patients. At 2 years, 39% of patients in the RT arm and 10% in the WS arm experienced grade 3 or 4 late toxicity according to Radiation Therapy Oncology Group criteria (P = .06). Disease-free survival (DFS) was significantly improved in the RT arm, with a hazard ratio of 1.68 (95% CI, 1.13 to 2.50; P = .01), but overall survival (OS) was not statistically different. CONCLUSION: Full-dose reirradiation combined with chemotherapy after salvage surgery significantly improved DFS, but had no significant impact on OS. An increase in both acute and late toxicity was observed.

French multicenter phase III randomized study testing concurrent twice-a-day radiotherapy and cisplatin/5-fluorouracil chemotherapy (BiRCF) in unresectable pharyngeal carcinoma: Results at 2 years (FNCLCC-GORTEC).

BACKGROUND: Unresectable carcinomas of the oropharynx and hypopharynx still have a poor long-term prognosis. Following a previous phase II study, this phase III multicenter trial was conducted between November 1997 and March 2002. METHODS: Nontreated, strictly unresectable cases were eligible. Twice-daily radiation: two fractions of 1.2 Gy/day, 5 days per week, with no split (D1-->D46). Total tumor doses: 80.4 Gy/46 day (oropharynx), 75.6 Gy/44 day (hypopharynx). Chemotherapy (arm B): Cisplatin 100 mg/m2 (D1, D22, D43); 5FU, continuous infusion (D1-->D5), 750 mg/m2/day cycle 1; 430 mg/m2/day cycles 2 and 3. RESULTS: A total of 163 evaluable patients. Grade 3-4 acute mucositis 82.6% arm B/69.5% arm A (NS); Grade 3-4 neutropenia 33.3% arm B/2.4% arm A (p < 0.05). Enteral nutrition through gastrostomy tube was more frequent in arm B before treatment and at 6 months (p < 0.01). At 24 months, overall survival (OS), disease-free survival (DFS), and specific survival (SS) were significantly better in arm B. OS: 37.8% arm B vs. 20.1% arm A (p = 0.038); DFS: 48.2% vs. 25.2% (p = 0.002); SS: 44.5% vs. 30.2% (p = 0.021). No significant difference between the two arms in the amount of side effects at 1 and 2 years. CONCLUSION: For these unresectable cases, chemoradiation provides better outcome than radiation alone, even with an "aggressive" dose-intensity radiotherapy schedule.
