RESUMO
INTRODUCTION: The response to induction chemotherapy (IC) predicts local control after conservative treatment of laryngeal, meso- and hypopharyngeal head and neck squamous cell carcinoma (HNSCC) and can thus help to avoid surgery. Single-cycle induction chemotherapy may help to maintain a low local recurrence rate while keeping the overall toxicity manageable. However, long-term data on single-cycle IC response by tumor location is lacking. METHODS: N = 102 patients with functionally inoperable primary HNSCC of the larynx (n = 43), hypopharynx (n = 42) or mesopharynx/tongue (n = 17) received one cycle of docetaxel (75 mg/m2, d1) plus cisplatin (30 mg/m2, d1-3) or carboplatin (AUC 1.5, d1-3) and a response evaluation 3 weeks later. Responders (≥ 30% tumor size reduction and ≥ 20% SUVmax decrease in 18F-FDG PET/CT) were recommended chemoradiotherapy (CRT), and non-responders surgery. RESULTS: The overall response rate was 72.5%. All 74 responders and 10 non-responders received primary CRT, and 18 patients received primary surgery after single-cycle IC. Overall 10-year local recurrence-free survival (LRFS) was 73.7%. Three-year LRFS was 88.2% (mesopharynx/tongue), 88.2% (larynx), and 73.3% (hypopharynx); p = 0.17. 3-year distant metastasis-free survival (DMFS) was 94.1% (mesopharynx/tongue), 88.0% (larynx) and 76.4% (hypopharynx); p > 0.05. This influenced the 3-year cancer-specific survival (CSS) for larynx (91.2%) vs. hypopharynx tumors (60.8%); p = 0.003, but CSS was not different to tumors in the mesopharynx/tongue (81.4%); p > 0.05. CONCLUSIONS: A single-cycle induction chemotherapy for HNSCC enables surgery plus adjuvant therapy as well as chemoradiotherapy. The long-term local and distant disease control was good but varied between tumors in the larynx and mesopharynx/tongue vs. hypopharynx.

BACKGROUND: Adding concurrent chemotherapy (CTx) to definitive radiation therapy (RT) in patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) improves overall survival. A comparable effect has been reported for hyperfractionated radiotherapy (HFX-RT) alone. Adding concurrent CTx to HFX-RT has been investigated in multiple trials, yet an evident effect on oncological outcomes and toxicity profile has not been established to date. Thus, the aim of the current study was to perform a meta-analysis on the clinical outcome and toxicity of the addition of CTx to HFX-RT. PATIENTS AND METHODS: We performed a literature search for randomized controlled trials comparing HFX-RT alone to HFX-RTâ¯+ concurrent CTx in patients with LA-HNSCC undergoing definite RT. A meta-analysis was performed using the event rates and effect-sizes for overall survival (OS), progression-free survival (PFS), cancer-specific survival (CSS), distant metastasis-free survival and distant recurrence-free interval (DMFS/DMFI) and locoregional recurrence (LRR) as investigated endpoints. Furthermore, we compared selected acute and late toxicities in the included studies. Statistical analysis was performed using the Microsoft Excel (Microsoft, Redmont, WA, USA) add-in MetaXL 5.3 (EpiGear International, Sunrise Beach, Australia), utilizing the inverse variance heterogeneity model. RESULTS: We identified six studies (nâ¯= 1280 patients) randomizing HFX-RT alone and the concurrent addition of CTx. OS was significantly improved in the HFX-RTâ¯+ CTx group (HRâ¯= 0.77, CI95%â¯= 0.66-0.89; pâ¯= <0.001). We found similar results in PFS (HRâ¯= 0.74, CI95%â¯= 0.63-0.87; pâ¯< 0.001) and CSS (HRâ¯= 0.72, CI95%â¯= 0.60-0.88; pâ¯= 0.001). In contrast, acute toxicities (≥grade 3 mucositis, ≥grade 3 dysphagia) and late adverse events including ≥grade 3 xerostomia, ≥grade 3 subcutaneous, ≥grade 3 bone, ≥grade 3 skin toxicity, and ≥grade 3 dysphagia did not significantly differ between the two groups. CONCLUSION: The addition of CTx to HFX-RT in the definitive treatment of advanced LA-HNSCC improves OS, CSS, PFS, and LRR without a significant increase in high-grade acute and late toxicities.

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.

PURPOSE: To appraise the ability of a radiomics signature to predict clinical outcome after definitive radiochemotherapy (RCT) of stage III-IV head and neck cancer. METHODS: A cohort of 110 patients was included in a retrospective analysis. Radiomics texture features were extracted from the gross tumor volumes contoured on planning computed tomography (CT) images. The cohort of patients was randomly divided into a training (70 patients) and a validation (40 patients) cohorts. Textural features were correlated to survival and control data to build predictive models. All the significant predictors of the univariate analysis were included in a multivariate model. The quality of the models was appraised by means of the concordance index (CI). RESULTS: A signature with 3 features was identified as predictive of overall survival (OS) with CIâ¯= 0.88 and 0.90 for the training and validation cohorts, respectively. A signature with 2 features was identified for progression-free survival (PFS; CIâ¯= 0.72 and 0.80); 2 features also characterized the signature for local control (LC; CIâ¯= 0.72 and 0.82). In all cases, the stratification in high- and low-risk groups for the training and validation cohorts led to significant differences in the actuarial curves. In the validation cohort the mean OS times (in months) were 78.9⯱ 2.1 vs 67.4⯱ 6.0 in the low- and high-risk groups, respectively, the PFS was 73.1⯱ 3.7 and 50.7⯱ 7.2, while the LC was 78.7⯱ 2.1 and 63.9⯱ 6.5. CONCLUSION: CT-based radiomic signatures that correlate with survival and control after RCT were identified and allow low- and high-risk groups of patients to be identified.

PURPOSE: The second primary cancer (SPC) incidence after treatment with platinum-based chemotherapy and cetuximab in combination with radiotherapy has not been previously reported. Our aim was to compare SPC risk following radiotherapy in combination with these agents for the treatment of head and neck squamous cell carcinoma (HNSCC). METHODS: The charts of 296 cases treated for loco-regionally advanced HNSCC between 2009 and 2015 were retrospectively reviewed for patient, tumor, and procedural characteristics. All patients were planned to undergo radiotherapy either with platinum compounds (group: Platinum) or monoclonal antibody cetuximab (group: Cetuximab). A third group of patients switched from platinum compounds to cetuximab due to toxicity (group: Switch). Treatment groups were evaluated for the incidence of SPC with log-rank test. Possible confounders were investigated with multivariate Cox's proportional hazards model. All tests were two-sided, and a pâ¯< 0.05 was set to indicate statistical significance. RESULTS: Median follow-up was 36 months. Platinum, Cetuximab, and Switch groups consisted of 158, 101, and 37 patients, respectively. Three-year overall survival in the whole cohort was 70%. The rate of SPC was comparable between Platinum (9.2%) and Cetuximab (11.5%) groups (pâ¯= 0.98), whereas the patients in the Switch group were exposed to a significantly higher incidence of SPC (23.3%) in 3 years (pâ¯= 0.01). The multivariate model indicated Switch to be the only variable correlating with an increased risk for SPC. CONCLUSIONS: The Switch strategy may expose the patients to an increased risk of developing SPC. The use of switch should be advocated with caution until robust pre-clinical and clinical data are available.

PURPOSE: Alternative and complementary medicine is defined as any substance or technique of non-allopathic medicine used to improve health and quality of life. The purpose of this prospective observational study was to evaluate the use of alternative and complementary medicine during radiotherapy. MATERIAL AND METHODS: A questionnaire was given the last week of treatment to all patients treated for breast cancer, prostate cancer or head and neck cancer in our centre in 2016. RESULTS: In 2016, 132 patients were included. Fifty-seven patients (43%) used alternative and complementary medicine during radiotherapy, more women (61%) than men (35%) (P=0.005). The use of alternative and complementary medicine varied according to locations: 44% of head and neck cancers, 57% of breast cancers and 24% of prostate cancers, but sex was the confounding factor. If alternative and complementary medicine was used before radiotherapy, 82% of patients used it during treatment, compared to 30% if they were naive (P<10-7). Healing touch (68%), homeopathy (26%) and magnetisers (21%) were the most used alternative and complementary medicines. Sixty-one percent of patients used alternative and complementary medicine to reduce skin and mucosal side effects of treatments, 28% to improve well-being, and 9% to treat cancer. Seventy-two percent of all patients would advise their loved one to use an alternative and complementary medicine and 87% would like information about them in the hospital. CONCLUSION: Alternative and complementary medicines are used more by women, and by patients who used them before radiotherapy. The desired effects are mainly to reduce the side effects of the treatments. More than 80% of patients, whether or not they use alternative and complementary medicine, demand medical information.

BACKGROUND: Cochlea sparing can reduce late ototoxicity in head and neck cancer patients treated with cisplatin-based radiochemotherapy. In this situation, a mean cochlear dose (MCD) constraint of 10â¯Gy has been suggested by others based on the dose-effect relationship of clinical data. We aimed to investigate whether this is feasible for primary and postoperative radiochemotherapy in locoregionally advanced tumors without compromising target coverage. PATIENTS AND METHODS: Ten patients treated with definitive and ten patients treated with adjuvant intensity-modulated radiotherapy (IMRT) and concurrent chemotherapy were investigated. The cochleae and a planning risk volume (PRV) with a 3â¯mm margin were newly delineated, whereas target volumes and other organs at risk were not changed. The initial plan was recalculated with a constraint of 10â¯Gy (MCD) on the low-risk side. The quality of the resulting plan was evaluated using the difference in the equivalent uniform dose (EUD). RESULTS: A unilateral MCD of below 10â¯Gy could be achieved in every patient. The mean MCD was 6.8â¯Gy in the adjuvant cohort and 7.6â¯Gy in the definitive cohort, while the non-spared side showed a mean MCD of 18.7 and 30.3â¯Gy, respectively. The mean PRV doses were 7.8 and 8.4â¯Gy for the spared side and 18.5 and 29.8â¯Gy for the non-spared side, respectively. The mean EUD values of the initial and recalculated plans were identical. Target volume was not compromised. CONCLUSION: Unilateral cochlea sparing with an MCD of less than 10â¯Gy is feasible without compromising the target volume or dose coverage in locoregionally advanced head and neck cancer patients treated with IMRT. A prospective evaluation of the clinical benefit of this approach as well as further investigation of the dose-response relationship for future treatment modification appears promising.

BACKGROUND: For head and neck squamous cell cancer (HNSCC), standard therapy consists of surgery, radiation, and/or chemotherapy. Antineoplastic immunotherapy could be an option in an adjuvant setting and is already in palliation. A functional immune system is a prerequisite for successful immunotherapy. However, effects of the standard-of-care therapy on the patients' immune system are not fully understood. METHODS: Peripheral blood mononuclear cells (PBMC) were collected from patients with HNSCC (nâ¯= 37) and healthy controls (nâ¯= 10). PBMC were stimulated with staphylococcal enterotoxin B (SEB). Simultaneous expression of various cytokines was measured in CD4+ and CD8+ T cells by multicolor flow cytometry, and polyfunctional cytokine expression profiles were determined on a single-cell basis. RESULTS: Expression levels of all measured cytokines in CD4+ T cells were higher in patients after chemoradiotherapy (CRT) as compared to untreated HNSCC patients or normal controls. After CRT, the frequency of polyfunctional CD4+ T cells, which simultaneously expressed multiple cytokines, was significantly increased as compared to untreated patients (pâ¯< 0.01). CONCLUSION: CRT increases polyfunctionality of CD4+ T cells in HNSCC patients, suggesting that standard-of-care therapy can promote immune activity in immune cells. These polyfunctional CD4+ T cells in the blood of treated HNSCC patients are expected to be responsive to subsequent immunotherapeutic approaches.

OBJECTIVES: The study aimed to investigate the impact of chemoradiotherapy (CRT) on speech and voice quality according to the anatomic localization of the head and neck cancer. METHODS: Thirty-four patients treated by CRT for advanced suprahyoid (N = 17) or infrahyoid (N = 17) cancer were assessed for speech function, videolaryngostroboscopy, Voice Handicap Index, blinded Grade, Roughness, Breathiness, Asthenia, Strain, and Instability, acoustic measurements, and aerodynamic measurements. Quality of life was evaluated using the European Organization for Research and Treatment of Cancer Head and Neck 35 (EORTC QLQ-H&N35) questionnaire. RESULTS: Patients treated for an infrahyoid tumor presented more severe values of Voice Handicap Index items, dysphonia, breathiness, asthenia, and some acoustic cues (Voice Turbulence Index, Soft Phonation Index, degree of unvoiced segments, and number of unvoiced segments) than patients treated for a suprahyoid tumor. The EORTC QLQ-H&N35 communication item was better in the suprahyoid patient group. CONCLUSIONS: Voice quality impairments associated with CRT are more severe in patients treated for advanced infrahyoid cancer, suggesting the need to develop specific posttherapy management of the dysphonia according to the tumor anatomical localization.

BACKGROUND: Cetuximab (CET) is a potent inhibitor of the epidermal growth factor receptor and has been shown to have activity in squamous cell carcinoma of the head and neck (SCCHN). We conducted a single-arm phase II trial of a combination therapy comprising cisplatin (CIS), CET and hyperfractionated accelerated radiotherapy (HART). PATIENTS AND METHODS: Patients with UICC stage III or IVA/B, M0 SCCHN were enrolled and treated with an initial dose of CET (400 mg/m2) and then with a weekly dosage of 250 mg/m2 during HART. HART was started with a prescribed dosage of 2.0 Gy per day for 3 weeks, followed by 1.4 Gy twice daily to a total dose of 70.6 Gy to the gross tumour volume. CIS (40 mg/m2) was administered weekly (days 1, 8, 15, 22, 29 and 36). The primary objective of the phase II study was to determine the 2year progression-free survival (PFS). RESULTS: Between November 2007 and November 2010, a total of 74 patients were enrolled in the study, of whom 65 were evaluable (83% were men). Median age was 56 years (range 37-69 years). An Oropharyngeal primary tumour was diagnosed in 49%, T4a,b in 65% and N2/3 in 96% of the patients. Of these patients, 85% were smokers or ex-smokers. Complete remission (CR) was observed in 23 patients (35%). The most common toxicity grade was ≥3, including mucositis (58%) and dysphagia (52%). The 2 and 5year overall survival rates were 64 and 41%, the 2 and 5year PFS rates were 45 and 32%, and the 2 and 5year locoregional control rates were 47 and 33%, respectively. CONCLUSION: The combination of weekly CIS with HART plus CET is a feasible regimen for these unfavourable smoking-induced cancers. However, the parallel US study (RTOG 0522) showed no advantage of the enhanced triple therapy compared to chemoradiotherapy alone.

Immunotherapy against head and neck cancer stem cells Immunologic therapies like antibodies in solid tumors like squamous cell cancer of the head and neck are administered either alone or in combination with radiation and chemotherapy. Despite some respectable successes, the effect of this therapy reaches its limits due the ability of the tumor to escape the immune system. Cancer stem cells seem to play an important role in this process due to their intrinsic resistance to conventional therapy and the ability to regenerate tumor heterogeneity. This way they substantially contribute to the formation of recurrences and metastases. Therefore, future immunotherapies should target specifically this subpopulation, possibly in combination with other therapeutic modalities. In this review the immunologic features of cancer stem cells and their potential as target for immunotherapies is summarized.

Immunotherapy is on the roll. After revolutionary effects in melanoma, immunotherapy is invading other locations. If current treatments, chemotherapies or targeted therapies block one pathway, immunotherapy should be understood as the activation of a whole system. Indeed, oncogenesis process is defined as an escape of the immune system and the stimulation of this system can block the carcinogenic process. The aim of the present review is to describe the place of immunotherapy in the treatment of solid cancers.

BACKGROUND: Head and neck paragangliomas are rare. They are usually slow-growing, benign, non-catecholamine secreting tumours, traditionally treated with surgical excision. Complications of surgical excision include lower cranial nerve palsies, stroke and death. METHOD: A retrospective case note analysis was conducted of patients with head and neck paragangliomas treated with a watch-and-scan policy from March 2003 to September 2015, and the relevant literature was reviewed. RESULTS: Fifteen head and neck paragangliomas were identified. None of the patients developed a new lower cranial nerve palsy or progression of their presenting hearing loss during the follow-up period. Five patients displayed an increase in maximum linear dimension of 4 mm over an average of 57.4 months. A review of the literature showed that a watch-and-surveillance scan policy is evolving as a treatment option for head and neck paragangliomas without malignant risk factors. CONCLUSION: Readily available surveillance scanning in head and neck paragangliomas enables the monitoring of head and neck paragangliomas, which may allow for avoidance of major surgery.

OBJECTIVES/HYPOTHESIS: Dysphagia is one of the most significant side effects of the treatment of head and neck cancer. Residue and aspiration are two indicators of dysphagia, but aspiration is historically the only indicator of interest, because it may impact health outcomes. Clinicians have anecdotally used residue as another marker of swallowing dysfunction, but it is understudied. This project investigated the impact of aspiration versus residue on function and quality of life (QoL) in these patients. STUDY DESIGN: Observational study. METHODS: A total of 168 head and neck cancer survivors with moderate to severe dysphagia were enrolled in a randomized clinical trial comparing two swallow therapy interventions. Data at time of entry were used for the current study. A modified barium swallow study was done to compute Penetration-Aspiration Scale (PAS) scores, percentage oral residue, and percentage pharyngeal residue with three bolus consistencies (5 mL thin, nectar, and pudding). The Performance Status Scale (PSS) and the Head Neck Cancer Inventory (HNCI) questionnaires were administered. Data were analyzed to determine associations between aspiration and residue estimates with function and QoL scores. RESULTS: Worsening aspiration and residue estimates were all correlated with decreased scores on the PSS functional scales (r = -0.190 to -0.324, P ≤ .031). However, only increasing residue estimates were significantly related to decreased patient-perceived QoL on the HNCI (r = -.178 to -.194, P < .046). This effect was more pronounced with oral versus pharyngeal residue. CONCLUSIONS: In this group of head and neck cancer survivors, penetration/aspiration and residue show independent effects. PAS affects functional status only, but residue affects both functional status and QoL. This study supports that residue should be considered a primary measurement of swallowing function and be a target for identification, treatment, and evaluation of swallowing. LEVEL OF EVIDENCE: 2c.

OBJECTIVES/HYPOTHESIS: To illustrate complex interdisciplinary decision making and the utility of modern endovascular techniques in the management of patients with carotid blowout syndrome (CBS). STUDY DESIGNS: Retrospective chart review. METHODS: Patients treated with endovascular strategies and/or surgical modalities were included. Control of hemorrhage, neurological, and survival outcomes were studied. RESULTS: Between 2004 and 2014, 33 patients had 38 hemorrhagic events related to head and neck cancer that were managed with endovascular means. Of these, 23 were localized to the external carotid artery (ECA) branches and five localized to the ECA main trunk; nine were related to the common carotid artery (CCA) or internal carotid artery (ICA), and one event was related to the innominate artery. Seven events related to the CCA/ICA or innominate artery were managed with endovascular sacrifice, whereas three cases were managed with a flow-preserving approach (covered stent). Only one patient developed permanent hemiparesis. In two of the three cases where the flow-preserving approach was used, the covered stent eventually became exposed via the overlying soft tissue defect, and definitive management using carotid revascularization or resection was employed to prevent further hemorrhage. In cases of soft tissue necrosis, vascularized tissues were used to cover the great vessels as applicable. CONCLUSIONS: The use of modern endovascular approaches for management of acute CBS yields optimal results and should be employed in a coordinated manner by the head and neck surgeon and the neurointerventionalist.
