Standard versus fractionated high-dose cisplatin plus radiation for locally advanced head and neck cancer: Results of the CisFRad (GORTEC 2015-02) randomized phase II trial

BACKGROUND

Chemoradiotherapy with high-dose cisplatin (HD-Cis: 100 mg/m2 q3w for three cycles) is the standard of care (SOC) in locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Cumulative delivered dose of cisplatin is prognostic of survival, even beyond 200 mg/m2 but high toxicity compromises its delivery.

AIM

Cisplatin fractionation may allow, by decreasing the peak serum concentration, to decrease toxicity. To date, no direct comparison was done of HD-Cis versus fractionated high dose cisplatin (FHD-Cis).

METHODS

This is a multi-institutional randomized phase II trial, stratified on postoperative or definitive chemoradiotherapy, comparing HD-Cis to FHD-Cis (25 mg/m2/d d1-4 q3w for 3 cycles) in patients with LA-HNSCC. The primary endpoint was the cumulative delivered cisplatin dose.

RESULTS

Between December 2015 and April 2018, 124 patients were randomized. Median cisplatin cumulative delivered dose was 291 mg/m2 (IQR: 251;298) in the FHD-Cis arm and 274 mg/m2 (IQR: 198;295) in the HD-Cis arm (P = 0.054). The proportion of patients receiving a third cycle of cisplatin was higher, with a lower proportion of grade 3-4 acute AEs in the FHD-Cis arm compared to the HD-Cis arm: 81 % vs. 64 % (P = 0.04) and 10 % vs. 17 % (P = 0.002), respectively. With a median follow-up of 48 months (IQR: 41;55), locoregional failure rate, PFS and OS were similar between the two arms.

CONCLUSION

Although the primary endpoint was not met, FHD-Cis allowed more cycles of cisplatin to be delivered with lower toxicity, when compared to SOC. FHD-Cis concurrently with RT is a treatment option which deserves further consideration.

A prospective randomized study comparing the efficacy between povidone-iodine gargling and benzydamine hydrochloride for mucositis prevention in head and neck cancer patients receiving concurrent chemoradiotherapy

Background

Concurrent chemoradiation (CCRT) has been the standard treatment for organ preservation or locally advanced head and neck cancer (LAHNC). Radiation-induced oral mucositis (RIOM) is an important treatment-limiting toxicity. Benzydamine hydrochloride was recommended to prevent oral mucositis. Povidone-iodine had also been adopted to use as an oral rinse to prevent mucositis.

Objective

This study compared the efficacy between benzydamine hydrochloride and 0.1% povidone-iodine to prevent RIOM in HNC patients who received concurrent chemoradiotherapy.

Methods

We conducted a randomized control study in HNC patients receiving CCRT with curative intent. The stratification factors were primary site of disease, treatment modality, chemotherapy regimen, and schedule. The primary outcome was RIOM assessed by Oral Mucositis Assessment Scale (OMAS). Secondary outcomes included RIOM assessed by NCI-CTCAE, use of analgesic, antibiotics and anti-fungal drugs, hospitalization, and participant satisfaction.

Results

There were 83 participants recruited for this study with 71 completing the trial. Demographic characteristics were well-balanced between both arms. The univariate regression analysis revealed that povidone-iodine correlated with less RIOM compared to benzydamine hydrochloride (coefficient -2.25, 95% CI -4.37 to -0.012, p-value 0.03). The incidence of grade III-IV CTCAE RIOM during the study period was 51.4% with benzydamine hydrochloride compared to 26.5% with 0.1% povidone iodine (p-value 0.032). The peak incidence of grade III-IV CTCAE RIOM occurred in the 7th week of treatment (40.5% vs. 11.8%, p-value 0.01). This indicated the efficacy of povidone-iodine to prevent severe RIOM which usually most severity in the last week of CCRT treatment. The multivariate analysis revealed that the CCRT setting (definitive vs. adjuvant) and gargling agents (povidone-iodine vs. benzydamine hydrochloride were the factors associated with RIOM.

Conclusion

This study demonstrated higher efficacy of 0.1% povidone-iodine gargle than benzydamine hydrochloride in mucositis prevention.

Serum selenium predicts achievement of full-dose cisplatin in concurrent chemoradiotherapy for locally advanced head and neck squamous cell carcinoma: A prospective, observational study

OBJECTIVE

Concurrent chemoradiotherapy (CCRT) with three-weekly high-dose cisplatin (100 mg/m²) is a standard treatment for locally advanced head and neck squamous cell carcinoma (HNSCC), but compliance with cisplatin is often poor due to various adverse events. The aim of this prospective, observational study was to determine the predictors of achievement of full-dose cisplatin.

METHODS

A prospective, observational study was conducted involving 60 patients who received CCRT with three-weekly high-dose cisplatin (100 mg/m²) for locally advanced HNSCC. Possible predictors affecting compliance with cisplatin were subjected to univariate and multivariate logistic regression analyses. Age, sex, primary site, clinical stage, treatment intent, history of hypertension, diabetes mellitus, smoking and drinking habits, body mass index, creatinine clearance, serum albumin, controlling nutrition status, trace elements (Fe, Zn, Cu, Se), acute kidney injury, white blood cell count decrease, neutrophilia, and weight loss were the variables evaluated.

RESULTS

Twenty-seven patients achieved full-dose cisplatin (300 mg/m²), and the other 33 patients did not. Multivariate logistic regression analysis showed that both mild renal dysfunction and selenium deficiency before treatment independently had negative impacts on achievement of full-dose cisplatin.

CONCLUSIONS

As well as renal function, selenium deficiency is a potential therapeutic target for CCRT with high-dose cisplatin in HNSCC patients.

A randomized phase 3 trial comparing nimotuzumab plus cisplatin chemoradiotherapy versus cisplatin chemoradiotherapy alone in locally advanced head and neck cancer

BACKGROUND

Because the addition of nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings.

METHODS

This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m² ) (CRT) or the same schedule of CRT with weekly nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed.

RESULTS

In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01).

CONCLUSIONS

The addition of nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m² cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.

Low-Dose vs. High-Dose Cisplatin: Lessons Learned From 59 Chemoradiotherapy Trials in Head and Neck Cancer

In locally advanced squamous cell carcinomas of the head and neck (LA-SCCHN), concurrent chemoradiotherapy is an integral part of multimodality management both in the adjuvant and in the definitive settings. Although de-intensification strategies have been propelled to the forefront of clinical research in human papillomavirus (HPV) positive oropharyngeal cancer, three cycles of 100 mg/m² cisplatin given every 3 weeks concurrently with conventionally fractionated external beam radiotherapy represent a cost-effective and globally accessible treatment option for the majority of LA-SCCHN cases. Based on four large randomized trials, this regimen has become the non-surgical standard of care for cisplatin-eligible patients. Nevertheless, the outcomes in terms of efficacy, toxicity, and compliance have been rather disappointing. Therefore, there is an unmet need to find a better alternative. With limited support from randomized trials, weekly low-dose cisplatin regimens have replaced the standard high-dose schedule at some institutions. Four prospective trials exploring radiotherapy with and without weekly low-dose cisplatin have been published. Two of them were conducted in the 1980s, one of which had a negative outcome, the third study provided insufficient information on toxicity, and the fourth trial had to be prematurely terminated due to poor accrual. Moreover, the findings of two phase III trials comparing the two concurrent cisplatin regimens favored the high-dose protocol. We performed a composite meta-analysis of 59 prospective trials enrolling a total of 5,582 patients. The primary endpoint was overall survival. Reflecting different radiotherapy fractionation schemes and treatment intents, three meta-analyses were carried out, one for postoperative conventional chemoradiotherapy, one for definitive conventional chemoradiotherapy, and one for definitive altered fractionation chemoradiotherapy. In the former two settings, both high- and low-dose regimens yielded similar survival outcomes, thus, the primary objective was not met. When given concurrently with altered fractionation radiotherapy, patients treated with high-dose cisplatin had significantly longer overall survival than those who received low-dose cisplatin. In this article we provide a synthetic view of the results, discuss the issue of cumulative dose, compare two vs. three cycles of high-dose cisplatin, and present our three-step recommendations for use of the current standard of care, high-dose cisplatin, in clinical practice.

Altered fractionation radiotherapy combined with concurrent low-dose or high-dose cisplatin in head and neck cancer: A systematic review of literature and meta-analysis

OBJECTIVES

Altered fractionation radiotherapy and concomitant chemoradiotherapy represent commonly used intensification strategies in the management of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). This meta-analysis compares compliance, safety, and efficacy between two single-agent cisplatin schedules given concurrently with altered fractionation radiotherapy.

METHODS

We systematically searched for prospective trials of patients with LA-SCCHN who received post-operative or definitive altered fractionation concurrent chemoradiotherapy. High-dose cisplatin once every three to four weeks (100 mg/m², 2 doses) was compared with a weekly low-dose protocol (≤50 mg/m², ≥4 doses). The primary outcome was overall survival. The secondary endpoints comprised treatment adherence, acute and late toxicities, and objective response rate.

RESULTS

Twelve studies with 1373 patients treated with definitive chemoradiotherapy were included. Compared to the weekly low-dose cisplatin regimen, the three- to four-weekly high-dose cisplatin regimen improved overall survival (p=.0185), was more compliant with respect to receiving all planned cycles of cisplatin (71% versus 95%, p=.0353), and demonstrated less complications in terms of severe (grade 3-4) acute mucositis and/or stomatitis (75% versus 40%, p=.0202) and constipation (8% versus 1%, p=.0066), toxic deaths (4%, versus 1%, p=.0168), 30-day mortality (8% versus 3%, p=.0154), and severe late subcutaneous fibrosis (21% versus 2%, p<.0001). Overall and complete response rates were similar between both chemotherapy schedules.

CONCLUSION

In chemoradiotherapy incorporating altered fractionation, two cycles of high-dose cisplatin with a three to four week interval are superior to weekly low-dose schedules. Further studies should identify those who might derive the greatest benefit from this intensified approach.

Chemotherapy for localized head and neck squamous cell cancers

Concomitant chemotherapy with cisplatin (100 mg/m every 3 weeks) improves outcome for high-risk patients in the postoperative setting and for inoperable disease. Toxicity is increased. Other schemes of potentiation are sometimes used to reduce toxicity, but efficiency is diminished. Cetuximab also improves outcome, but there has been no direct comparison with cisplatin. Immunotherapy is currently being evaluated in association with radiation therapy. Trials are ongoing to evaluate the impact of de-escalation for human papillomavirus-positive patients. The association of docetaxel, cisplatin, and 5-fluorouracil is the standard of induction; it is also the standard treatment for laryngeal preservation. Many trials have attempted to compare the concomitant approach with the sequential treatment; none have managed to show a difference between the two. After induction chemotherapy, there is still no standard of potentiation of radiotherapy.

Exclusive concurrent radiochemotherapy for advanced head and neck cancers with 'fractionated' 5-fluorouracil and cisplatin

Concurrent radiochemotherapy (CRC) is a standard treatment in patients with inoperable locoregionally advanced ear-nose-throat (ENT) cancer. We report the safety and efficacy of CRC with daily fractionated 5-fluorouracil and cisplatin ('F' 5FU-CDDP) in a monocentric retrospective cohort. From January 2006 to August 2012, all patients with unresectable (or inoperable) nonmetastatic locoregionally advanced ENT cancer treated curatively by means of radiotherapy (normal fractionated 70 Gy to the macroscopic tumor and prophylactic 50 Gy) with three courses (week 1-week 4-week 7) of 'F' 5FU-CDDP regimen (800 mg/m/day of 5-fluorouracil and 20 mg/m/day of CDDP from day 1 to day 4) were included. Seventy patients underwent CRC (86% men, median age 58 years old, 100% squamous cell carcinoma, 97% stage III/IV). Fifty-six patients received the three complete courses of chemotherapy with cumulative doses of CDDP of 217 mg/m/patient (dose intensity ratio of 90.5%). After a median follow-up period of 30.7 months, median overall and disease-free survivals were 34.1 [95% confidence interval (CI) (21.6-56.8)] and 50.2 months [95% CI (17.4-NA)] with 71% [95% CI (57.5-81)] and 67% [95% CI (51.8-78.5)] for locoregional control at 2 and 5 years, respectively. In all, 58.5% of grade 3 or higher mucositis and 24% of radioepithelitis were observed, but only 11.5, 3, and 1.5% of grade 3 or higher neutropenia, nephrotoxicity, and neurotoxicity were observed, respectively. No deaths from toxicity occurred. CRC with three courses of 'F' 5FU-CDDP appears effective and could be an alternative to standard CRC treatment. Randomized studies are required to be able to use this treatment regimen routinely.

Weekly Low-Dose Versus Three-Weekly High-Dose Cisplatin for Concurrent Chemoradiation in Locoregionally Advanced Non-Nasopharyngeal Head and Neck Cancer: A Systematic Review and Meta-Analysis of Aggregate Data

BACKGROUND

Three-weekly high-dose cisplatin (100 mg/m²) is considered the standard systemic regimen given concurrently with postoperative or definitive radiotherapy in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). However, due to unsatisfactory patient tolerance, various weekly low-dose schedules have been increasingly used in clinical practice. The aim of this meta-analysis was to compare the efficacy, safety, and compliance between these two approaches.

MATERIALS AND METHODS

We systematically searched literature for prospective trials of patients with LA-SCCHN who received postoperative or definitive conventionally fractionated concurrent chemoradiation. Radiation doses were usually 60-66 gray (Gy) in the postoperative setting and 66-70 Gy in the definitive setting. Standard, three-weekly high-dose cisplatin (100 mg/m², 3 doses) was compared with the weekly low-dose protocol (≤50 mg/m², ≥6 doses). The primary endpoint was overall survival. Secondary outcomes comprised response rate, acute and late adverse events, and treatment compliance.

RESULTS

Fifty-two studies with 4,209 patients were included in two separate meta-analyses according to the two clinical settings. There was no difference in treatment efficacy as measured by overall survival or response rate between the chemoradiation settings with low-dose weekly and high-dose three-weekly cisplatin regimens. In the definitive treatment setting, the weekly regimen was more compliant and significantly less toxic with respect to severe (grade 3-4) myelosuppression (leukopenia p = .0083; neutropenia p = .0024), severe nausea and/or vomiting (p < .0001), and severe nephrotoxicity (p = .0099). Although in the postoperative setting the two approaches were more equal in compliance and with clearly less differences in the cisplatin-induced toxicities, the weekly approach induced more grade 3-4 dysphagia (p = .0026) and weight loss (p < .0001).

CONCLUSION

In LA-SCCHN, current evidence is insufficient to demonstrate a meaningful survival difference between the two dosing regimens. Prior to its adoption into routine clinical practice, the low-dose weekly approach needs to be prospectively compared with the standard three-weekly high-dose schedule.

IMPLICATIONS FOR PRACTICE

Given concurrently with conventional radiotherapy in locally advanced head and neck cancer, high-dose three-weekly cisplatin has often been replaced with weekly low-dose infusions to increase compliance and decrease toxicity. The present meta-analysis suggests that both approaches might be equal in efficacy, both in the definitive and postoperative settings, but differ in toxicity. However, some toxicity data can be influenced by unbalanced representation, and the conclusions are not based on adequately sized prospective randomized studies. Therefore, low-dose weekly cisplatin should not be used outside clinical trials but first prospectively studied in adequately sized phase III trials versus the high-dose three-weekly approach.

Efficacy and mucosal toxicity of concomitant chemo-radiotherapy in patients with locally-advanced squamous cell carcinoma of the head-and-neck in the light of a novel mathematical model

BACKGROUND

In the last several decades, combined radiotherapy (RT) and chemotherapy (CT) have been recognized as feasible in locally-advanced-squamous-cell-carcinoma of the head-and-neck (LA-HNSCC). Several meta-analyses identified concurrent RT+CT (CRT) most likely effective approach respect to RT-alone. However, radiobiological models comparing different chemotherapeutic schedules against delivered RT fractionation schedule for overall survival and toxicity are still needed.

METHODS AND MATERIALS

Based on 9 randomized trials (2785 patients), radiobiological models and multivariate logistic regression model were used to derive dose-response curves and estimate the 5-year-overall survival (OS) and ≥G3 acute mucositis rate of CRT or RT-alone.

RESULTS

Equivalent dose at 2 Gy/fraction (EQD2) was calculated using the linear quadratic model. The effect of CRT schedules, considering the CT type and its administration schedule and the HPV status of tumors were estimated using the univariate/multivariate logistic regression. The multivariate logistic regression model for 5y-OS indicated EQD2 and the type of CT, the chemo-sensitization fraction and the HPV status significant prognostic factors, while for toxicity both EQD2 and the concomitant administration of 5-fluorouracil (5Fu) resulted as significant prognostic factors. Combined schedules cisplatin (DDP)+/-5Fu+RT produced the higher OS compared with combined carboplatin+/-5Fu+RT or RT-alone. The concomitant administration of Fu and schedule with high EQD2 increase the rate of observed ≥G3 acute mucositis.

CONCLUSION

Multivariate logistic regression models can be used to predict CRT effect in terms of OS and ≥G3-mucositis, contributing to the identification of novel treatment schedules.

[Observance and results of concurrent chemoradiotherapy after induction chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil for locally advanced head and neck cancers]

PURPOSE

Retrospectively evaluate the safety, feasibility and efficacy of concomitant chemoradiotherapy after induction chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil for locally advanced head and neck cancers.

PATIENTS AND METHODS

Patients' data from three radiotherapy centres in South of France, with locally advanced head and neck cancers, and treated between December 2007 and July 2013 by concomitant chemoradiotherapy, after induction chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil, were analysed. Adverse effects were graduated according to CTCAE v3.0 criteria. Overall survival and disease-free survival were calculated according to Kaplan-Meier method.

RESULTS

One hundred and sixty-eight patients, mostly oropharynx (38%) T4 (46%) N2 (54%) tumors, received, after induction chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil, a concomitant chemoradiotherapy with platin or cetuximab, which delivered 66 to 70Gy. Grade 3-4 adverse effects were less frequent in the group of patients who received cisplatin (with or withour 5-fluoro-uracil) at 100mg/m(2) each 21 days compared to cetuximab (radiomucositis: 32.5% vs 61%, P=0.018; radioepithelitis: 13% vs 61 %, P<0.0001). Chemopotentiation was incomplete for 21% of patients without impacting survival. Two years overall survival and disease-free survival were respectively of 81% and 64%. Lymph nodes status and WHO status significantly influenced these survivals (overall survival 84% if N<3 vs 56% if N3, P=0.017 and 85 % if WHO status ≤ 1 vs 50% if WHO status>1, P=0.006; disease-free survival 66% if N<3 vs 47% if N3, P=0.046).

CONCLUSION

The association of induction chemotherapy by docetaxel, cisplatin and 5-fluoro-uracil and concomitant chemoradiotherapy shows satisfying results with an acceptable toxicity. The terms of the chemopotentiation and its superiority to a single concomitant chemoradiotherapy treatment still remain to be clarified.

Predictive factors of head and neck squamous cell carcinoma patient tolerance to high-dose cisplatin in concurrent chemoradiotherapy

Although high-dose cisplatin is the standard regimen of concurrent chemoradiotherapy (CCRT) for locally advanced head and neck squamous cell carcinoma (HNSCC), varying levels of patient tolerance towards cisplatin have been reported, and the predictive factors of cisplatin tolerance remain to be elucidated. The present study retrospectively reviewed newly diagnosed HNSCC patients who received CCRT. Cisplatin (80 mg/m²) was administered every 3 weeks. The proportion of high-dose cisplatin-tolerant patients (cumulative cisplatin dose, ≥200 mg/m²) was determined, and the predictive factors of cisplatin tolerance were analyzed in a logistic regression analysis. Between June 2006 and March 2013, a total of 159 patients were treated with CCRT. The median follow-up time was 36.7 months. A total of 73 patients (46%) tolerated a cumulative cisplatin dose ≥200 mg/m²; male gender [odds ratio (OR), 25.00; P=0.005] and high body surface area (BSA) (>1.80 m²; OR, 2.21; P=0.032) were significantly predictive of high-dose cisplatin tolerance. The high-dose cisplatin-tolerant patients had a significantly higher complete response (CR) rate (82 vs. 67%, P=0.045); however, there were no significant between-group differences in the 3-year OS (79.5 vs. 81.2%, P=0.59) or PFS (70.4 vs. 44.6%, P=0.076) by cisplatin tolerance. In clinical practice, approximately one-half of the patients tolerated high-dose cisplatin in CCRT. Male gender and high BSA could be predictive of cisplatin tolerance.

Cumulative cisplatin dose in concurrent chemoradiotherapy for head and neck cancer: A systematic review

BACKGROUND

The optimal cumulative dose and timing of cisplatin administration in various concurrent chemoradiotherapy protocols for nonmetastatic head and neck squamous cell carcinoma (HNSCC) has not been determined.

METHODS

The absolute survival benefit at 5 years of concurrent chemoradiotherapy protocols versus radiotherapy alone observed in prospective randomized trials reporting on the use of cisplatin monochemotherapy for nonnasopharyngeal HNSCC was extracted. In the case of nonrandomized studies, the outcome results at 2 years were compared between groups of patients receiving different cumulative cisplatin doses.

RESULTS

Eleven randomized trials and 7 nonrandomized studies were identified. In 6 definitive radiotherapy phase III trials, a statistically significant association (p = .027) between cumulative cisplatin dose, independent of the schedule, and overall survival benefit was observed for higher doses.

CONCLUSION

Results support the conclusion that the cumulative dose of cisplatin in concurrent chemoradiation protocols for HNSCC has a significant positive correlation with survival. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2151-E2158, 2016.

[Squamous cell carcinoma of the hypopharynx and larynx: evidence-based care]

Squamous cell carcinomas of larynx and hypopharynx can be treated by surgery and/or radiotherapy according to tumor size. For small tumors, the results are similar. For locally advanced tumors, the surgical approach is mutilating and requires a total (pharyngo)laryngectomy. Exclusive chemoradiotherapy has shown its interest at the cost of late sequelae. In order to reduce these effects and mutilation, induction chemotherapy with cisplatin, docetaxel and 5FU for organ preservation becomes the standard treatment but there are no solid studies comparing this approach with the exclusive chemoradiotherapy. And it is not possible to conclude as to the superiority of a scheme in terms of overall survival. When chemotherapy is chosen, the modalities of any potentiation of radiation have not been yet established.

[Quality assurance in head and neck medical oncology]

In medical oncology, how can we be sure that the right drug is being administered to the right patient at the right time? The implementation of quality assurance criteria is important in medical oncology, in order to ensure that the patient receives the best treatment safely. There is very little literature about quality assurance in medical oncology, as opposed to radiotherapy or cancer surgery. Quality assurance must cover the entire patient care process, from the diagnosis, to the therapeutic decision and drug distribution, including its selection, its preparation and its delivery to the patient (administration and dosage), and finally the potential side effects and their management. The dose-intensity respect is crucial, and its reduction can negatively affect overall survival rates, as shown in breast and testis cancers for example. In head and neck medical oncology, it is essential to respect the few well-standardized recommendations and the dose-intensity, in a population with numerous comorbidities. We will first review quality assurance criteria for the general medical oncology organization and then focus on head and neck medical oncology. We will then describe administration specificities of head and neck treatments (chemoradiation, radiation plus cetuximab, postoperative chemoradiation, induction and palliative chemotherapy) as well as their follow-up. Lastly, we will offer some recommendations to improve quality assurance in head and neck medical oncology.
