RESUMO

OBJECTIVES: Pharyngolaryngeal and oesophagogastric cancers present with swallowing symptoms and as such, their clinical evaluation traverses boundaries between different specialties. We studied the incidence and significance of interspecialty cancer referrals (ICRs), that is, pharyngolaryngeal cancers first evaluated by gastroenterology and oesophagogastric cancers first evaluated by otolaryngology. DESIGN: A subset analysis of our Integrated Aerodigestive Partnership's audit dataset, of all ICR patients, and an equal number of controls matched for age, sex and cancer subsite. MAIN OUTCOME MEASURES: Information about patient age and presenting symptoms was recorded. The relationship between symptoms and ICR risk was examined with binary logistic regression. Referral-to-diagnosis latency was compared between ICR and control patients with unpaired Student's t test. Cox regression was used to identify independent predictors of overall survival. RESULTS: Of 1130 patients with pharyngolaryngeal and oesophagogastric cancers between 2008 and 2018, 60 diagnoses (5.3%) were preceded by an ICR. Referral-to-diagnosis latency increased from 43 ± 50 days for control patients to 115 ± 140 days for ICR patients (P < .0001). Dysphagia significantly increased the risk of an ICR (odds ratio 3.34; 95% CI 1.30-8.56), and presence of classic gastroesophageal reflux symptoms (heartburn or regurgitation; OR 0.25; 95% CI 0.08-0.83) and "distal" symptoms (nausea/vomiting, abdominal pain or dyspepsia; OR 0.23; 95% CI 0.08-068) significantly reduced the risk. Eleven pharyngolaryngeal cancers (of 26; 42%) were missed by gastroenterology, and eight (of 34; 24%) oesophageal cancers were missed by otolaryngology. An ICR was an independent adverse prognostic risk factor on multivariable analysis (hazard ratio 1.76; 95% CI 1.11-2.73; P < .02; log-rank test). Two systemic root causes were poor visualisation of pharynx and larynx by per-oral oesophago-gastro-duodenoscopy (OGD) for pharyngolaryngeal cancers, and poor sensitivity (62.5%) of barium swallow when it was used to 'evaluate' oesophageal mucosa. CONCLUSIONS: An interspecialty cancer referral occurs in a significant proportion of patients with foregut cancers. It almost triples the time to cancer diagnosis and is associated with a high incidence of missed cancers and diminished patient survival. It is a complex phenomenon, and its reduction requires an integrated approach between primary and secondary care, and within secondary care, to optimise referral pathways and ensure appropriate and expeditious specialist evaluation.

RESUMO

PURPOSE: The role of postoperative irradiation to contralateral non-involved neck nodes in lateralized carcinoma of the head and neck is not clear. The contralateral neck failure rate in head and neck carcinoma treated postoperatively with ipsilateral neck irradiation only was evaluated. METHODS: Patients with carcinoma of the oral cavity, oropharynx, or hypopharynx without midline extension treated between 1990 and 2016 were analyzed. After tumor resection and neck dissection (ND), radiotherapy was given to the primary tumor site and ipsilateral neck. High-risk patients additionally received concurrent chemotherapy. Freedom from contralateral neck recurrence (FCNR), locoregional control rate (LRC), overall survival (OS), and disease-free survival (DFS) were evaluated. RESULTS: 197 patients (median age 60.7 years, 66.5% males, 52.8% oropharyngeal carcinomas) were analyzed. Complete resection (R0) was achieved in 85.8% of cases. Ipsilateral ND was performed in all patients and contralateral ND in 144 patients (73.1%). Concurrent chemotherapy was given to 59 patients (30.0%). After a median follow-up of 45.5 months, OS and DFS of all patients were 73.6% and 70.9% at 5 years, respectively. A total of 45 patients (22.8%) suffered from a locoregional recurrence, lymph node metastases of the contralateral neck developed in 12 patients (6.1%) only. There was no significant difference in contralateral nodal failure rate with or without performance of contralateral ND. CONCLUSION: Regional failure of the contralateral neck was low after surgery and ipsilateral neck irradiation in head and neck carcinomas without midline extension, supporting evidence that contralateral neck radiotherapy can safely be omitted in selected cases.

RESUMO

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-RT + 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 (n = 1280 patients) randomizing HFX-RT alone and the concurrent addition of CTx. OS was significantly improved in the HFX-RT + CTx group (HR = 0.77, CI95% = 0.66-0.89; p = <0.001). We found similar results in PFS (HR = 0.74, CI95% = 0.63-0.87; p < 0.001) and CSS (HR = 0.72, CI95% = 0.60-0.88; p = 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.

RESUMO

PURPOSE: The aim of this retrospective study was to evaluate the clinical outcome of a previously defined low-risk patient population with completely resected (R0) squamous cell carcinoma of the oral cavity, oropharynx, larynx (pT1-3, pN0-pN2b), hypopharynx (pT1-2, pN0-pN1), and the indication for postoperative radio(chemo)therapy. PATIENTS AND METHODS: According to predefined criteria, 99 patients with head and neck squamous cell carcinoma (SCC) who were treated at our institution from January 1, 2005 to December 31, 2014, were available for analysis. The Kaplan-Meier method was used for calculating survival and incidence rates. For univariate comparative analysis, the log-rank test was used for analyzing prognostic clinicopathologic parameters. RESULTS: Median follow-up was 67 months. Cumulative overall (OS) and disease-free survival (DFS) were 97.9%/94.7%/88.0% and 96.9%/92.6%/84.7% after 1, 2, and 5 years, respectively. Cumulative incidence of loco-regional recurrence (LRR), distant metastases (DM), and second cancer (SC) were 1.0%/1.0%/4.9%, 0.0%/3.4%/5.8%, and 2.1%/4.2%/13.1%, respectively. In univariate comparative analysis, location of the primary tumor in the oropharynx was a significant predictor for increased OS (p = 0.043) and DFS (p = 0.048). CONCLUSION: Considering the low disease relapse rates and high rates of therapy-induced late side effects, as well as the increased risk of developing SC, a prospective multicentric trial investigating de-escalation of radiotherapy in this clearly defined low-risk patient population was started and is still recruiting patients (DIREKHT-Trial, NCT02528955).

RESUMO

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 p < 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 (p = 0.98), whereas the patients in the Switch group were exposed to a significantly higher incidence of SPC (23.3%) in 3 years (p = 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.

RESUMO

PURPOSE: To evaluate feasibility, disease control, survival, and toxicity after adaptive 18F-fluorodeoxyglucose (FDG) positron emisson tomography (PET) guided radiotherapy in patients with recurrent and second primary head and neck squamous cell carcinoma. METHODS: A prospective trial investigated the feasibility of adaptive intensity modulated radiotherapy (IMRT) ± concomitant cetuximab in 10 patients. The primary endpoint was achieving a 2-year survival free of grade >3 toxicity in ≥30% of patients. Three treatment plans based on 3 PET/CT scans were consecutively delivered in 6 weeks. The range of dose painting was 66.0-85.0 Gy in the dose-painted tumoral volumes in 30 fractions. RESULTS: Two-year locoregional and distant control rates were 38 and 76%, respectively. Overall and disease-free survival at 2 years was 20%. No grade 4 or 5 acute toxicity was observed in any of the patients, except for arterial mucosal hemorrhage in 1 patient. Three months after radiotherapy, grade 4 dysphagia and mucosal wound healing problems were observed in 1/7 and 1/6 of patients, respectively. Grade 5 toxicity (fatal bleeding) was seen in 2 patients, at 3.8 and 4.1 months of follow-up. Data on 2­year toxicity could only be assessed in 1 of the 2 surviving patients, in whom grade 4 mucosal wound healing problems were observed; no other grade >3 toxicity was observed. In this respect, a 30% 2­year survival free of grade >3 toxicity will not be achieved. CONCLUSIONS: Adaptive PET-guided reirradiation is feasible. However, due to slow accrual and treatment results that seemed inconsistent with achieving the primary endpoint, the trial was stopped early.

RESUMO

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.

RESUMO

OBJECTIVE: To examine the outcomes of reirradiation for recurrent head and neck cancers using different modalities. METHODS: This retrospective study included 26 patients who received charged particle radiotherapy (CP) and 150 who received photon radiotherapy (117 CyberKnife radiotherapy [CK] and 36 intensity-modulated radiotherapy [IMRT]). Inverse probability of treatment weighting (IPTW) involving propensity scores was used to reduce background selection bias. RESULTS: Higher prescribed doses were used in CP than photon radiotherapy. The 1­year overall survival (OS) rates were 67.9% for CP and 54.1% for photon radiotherapy (p = 0.15; 55% for CK and 51% for IMRT). In multivariate Cox regression, the significant prognostic factors for better survival were nasopharyngeal cancer, higher prescribed dose, and lower tumor volume. IPTW showed a statistically significant difference between CP and photon radiotherapy (p = 0.04). The local control rates for patients treated with CP and photon radiotherapy at 1 year were 66.9% (range 46.3-87.5%) and 67.1% (range 58.3-75.9%), respectively. A total of 48 patients (27%) experienced toxicity grade ≥3 (24% in the photon radiotherapy group and 46% in the CP group), including 17 patients with grade 5 toxicity. Multivariate analysis revealed that younger age and a larger planning target volume (PTV) were significant risk factors for grade 3 or worse toxicity. CONCLUSION: CP provided superior survival outcome compared to photon radiotherapy. Tumor volume, primary site (nasopharyngeal), and prescribed dose were identified as survival factors. Younger patients with a larger PTV experienced toxicity grade ≥3.

RESUMO

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.

RESUMO

OBJECTIVES: Identify predictors of outcome in patients with recurrent/metastatic head and neck squamous cell carcinoma (RMHNSCC) treated with weekly cetuximab and paclitaxel (CP). STUDY DESIGN: Retrospective analysis. METHODS: Patients with RMHNSCC treated with CP were identified and patient data was recorded. The Kaplan-Meier method was used to estimate outcomes, and Cox regression analysis was used to examine outcome predictors. RESULTS: Fifty-nine patients initiated CP between January 2007 and June 2014. Median age was 56 (range: 39-80) years. The most common primary sites were the oropharynx in 22 (37%) patients, oral cavity in 19 (32%), and larynx in 11 (19%). Eastern Cooperative Oncology Group performance status (ECOG PS) was 0 in seven (12%), 1 in 32 (54%), and 2 in 16 (28%) patients. In 44 (75%) patients, CP was used as a first-line R/M regimen. Median number of cycles was five (range: 1-29). Dose modifications were necessary in 27 (46%) patients. The objective response rate was 47.5%, with 27 (45.8%) partial responses and one (2%) complete response. With a median follow-up of 13.4 months, median progression-free (PFS) and overall survival (OS) were 7.7 and 13.2 months, respectively. On multivariable analysis, an ECOG of 2 of 3 was associated with inferior OS (hazard ratio [HR]: 3.94; P = 0.01; 95% confidence interval [CI]: 1.1-14.04) and PFS (HR: 7.29; P < 0.01; 95% CI: 2.1-26.0) compared to an ECOG 0 of 1. First-line CP administration was associated with superior PFS compared to second line (HR: 2.6; P = 0.02; 95% CI:1.2-5.5). CONCLUSIONS: CP is well tolerated in this population of patients, with favorable tumor efficacy. First-line use and an ECOG 0 of 1 points appears to confer superior outcomes. LEVEL OF EVIDENCE: 4.

RESUMO

OBJECTIVE: The chemokine CXCL12 and its receptor CXCR4 can affect tumor growth, recurrence, and metastasis. We tested the hypothesis that the CXCL12 and CXCR4 expression influences the prognosis of patients with inoperable head and neck cancer treated with definite radiotherapy or chemoradiotherapy. METHODS: Formalin-fixed paraffin-embedded pretreatment tumor tissue from 233 patients with known HPV/p16(INK4A) status was analyzed. CXCL12 and CXCR4 expressions were correlated with pretreatment parameters and survival data by univariate and multivariate Cox regression. RESULTS: CXCL12 was expressed in 43.3 % and CXCR4 in 66.1 % of the samples and both were correlated with HPV/p16(INK4A) positivity. A high CXCL12 expression was associated with increased overall survival (p = 0.036), while a high CXCR4 expression was associated with decreased metastasis-free survival (p = 0.034). CONCLUSION: A high CXCR4 expression could be regarded as a negative prognostic factor in head and neck cancer because it may foster metastatic spread. This may recommend CXCR4 as therapeutic target for combating head and neck cancer metastasis.

RESUMO

Radiotherapy is an effective treatment for head and neck cancers but patients often experience side effects, which lead to malnutrition. Morbidity related to weight loss during treatment may include dehydration, hospitalization, compromised treatment efficacy, and reduced quality of life and may impact survival hence the importance of early nutritional management prior to radiotherapy. Multiple interventions have been implemented to help ameliorate the impact of treatment on weight loss and nutritional status, including the use of percutaneous endoscopic gastrostomy tubes. The goal of this overview is to search the predictive factors of malnutrition and an overview of the different types of nutritional interventions and their impact on the local control of the disease, mortality and quality of life of patients treated with radiotherapy or concomitant chemoradiotherapy.

RESUMO

IMPORTANCE: The US veteran population represents a unique cohort of patients in whom human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) has yet to be investigated. OBJECTIVE: To investigate the incidence and characteristics of HPV-positive HNSCC within the veteran population. DESIGN, SETTING, AND PARTICIPANTS: Retrospective medical record review including patients with HNSCC diagnosed between January 1, 2010, and November 15, 2013, from the VA Greater Los Angeles Healthcare System. Data were collected between November 16, 2013, and June 19, 2014, and analyzed between June 20, 2014, and March 26, 2015. EXPOSURES: Chemoradiation therapy, radiation therapy, surgery, or no treatment. MAIN OUTCOMES AND MEASURES: We determined HPV positivity by p16 testing. Demographic and clinicopathologic information and overall survival were extracted from medical records. RESULTS: We identified 150 patients with the diagnosis of HNSCC. Sixty-nine patients had HPV-positive tumors (46%), and 65 (43%) had HPV-negative tumors (16 did not have HPV testing). Age at diagnosis ranged from 44 to 94 years (mean, 64.6 [SD, 8.0] years), and median (interquartile range) follow-up was 16.7 (8.7-27.3) years. Tumor location differed significantly between the 2 groups, with an HPV-positive predominance in the oropharynx (43 of 57 [75%]; P < .001). The HPV-positive patients were more likely to be treated primarily with combined chemoradiation therapy than radiation therapy or surgery (P < .001). T4 tumors had a nearly 9 times greater rate of mortality compared with T1 tumors (HR, 8.52 [95% CI, 2.60-18.40; P < .001); N3 disease was associated with 7.18 times greater mortality (HR, 7.18 [95% CI, 1.99-12.26]; P < .001) compared with N1 disease; and M1 disease was associated with 6.0 times greater mortality (HR, 5.99 [95% CI, 2.59-13.81]; P < .001). There were 42 total deaths during follow-up, 25 in the HPV-negative group and 17 in the HPV-positive group, with a nonsignificantly higher overall survival among HPV-positive patients independent of alcohol or tobacco use history (P = .09). CONCLUSIONS AND RELEVANCE: Previous studies have found that the proportion of HPV-positive HNSCC in the general population ranges between 20% and 75%. Although the incidence of HPV-positive HNSCC in the Veterans Affairs population is comparable, these patients have unique risk factors and demographic characteristics that may suggest different prognostic factors for HPV-positive HNSCC in this population. Nonetheless, HPV-positive tumors still seem to portend a better overall prognosis regardless of alcohol or tobacco history among the Veterans Affairs population.

RESUMO

BACKGROUND: The two-week wait referral system for suspected cancer was introduced in the National Health Service in 2000. This study aimed to identify areas for improvement to the two-week wait system by seeking the opinions of doctors working in primary and secondary care. METHOD: A questionnaire was distributed to general practitioners and head and neck surgeons within North West England with ethical consent. RESULTS: Twenty-seven general practitioners and 15 head and neck surgeons responded. Of the general practitioners, 59.3 per cent declared that they never attend training on referrals in this specialty. Overall, 59.3 per cent of general practitioners and 86.7 per cent of head and neck surgeons felt that the two-week wait system could be improved. CONCLUSION: The main areas for further work are development of pre-referral communication between primary and secondary care along with development of practical educational measures for general practitioners.

RESUMO

PURPOSE: Locoregional recurrence remains the main pattern of failure after primary combined modality treatment of squamous cell carcinoma of the head and neck (SCCHN). We compared the efficacy and toxicity of either cisplatin or cetuximab in combination with re-irradiation (ReRT) for recurrent unresectable SCCHN. Various clinicopathological factors were investigated to establish a prognostic score. PATIENTS AND METHODS: Between 2007 and 2014, 66 patients with recurrent SCCHN originating in a previously irradiated area received cetuximab (n = 33) or cisplatin-based chemotherapy (n = 33) concomitant with ReRT. Toxicity was evaluated weekly and at every follow-up visit. Physical examination, endoscopy, CT or MRI scans were used to evaluate response and disease control. RESULTS: With a mean follow-up of 18.3 months, the 1-year overall survival (OS) rates for Re-RT with cetuximab and cisplatin-based chemotherapy were 44.4 and 45.5% (p = 0.352), respectively. At 1 year, local control rates (LCR) were 46.4 and 54.2% (p = 0.625), freedom from metastases (FFM) rates 73.6 and 81% (p = 0.842), respectively. Haematological toxicity ≥ grade 3 occurred more often in the cisplatin group (p < 0.001), pain ≥ grade 3 was increased in the cetuximab group (p = 0.034). A physiological haemoglobin level and a longer interval between primary RT and ReRT, proved to be significant prognostic factors for OS (multivariate: p = 0.003, p = 0.002, respectively). Site of the recurrence and gross target volume (GTV) did not show a significant impact on OS in multivariate analysis (p = 0.160, p = 0.167, respectively). A prognostic-score (1-4 points) based on these four variables identified significantly different subgroups: 1-year OS for 0/1/2/3/4 prognostic points: 10, 38, 76, 80 and 100%, respectively (p < 0.001). CONCLUSION: Both cetuximab- and cisplatin-based ReRT of SCCHN recurrences are feasible and effective treatment options with comparable results in terms of tumour control and survival. Acute adverse events may differ slightly. Our prognostic score could help to identify appropriate patients for ReRT and stratify patients within future clinical trials.

RESUMO

PURPOSE: Concurrent chemoradiotherapy (CRT) is the standard treatment for advanced head and neck squamous cell carcinoma. In this phase II randomized study, the efficacy and toxicity of docetaxel, cisplatin and 5-fluorouracil induction chemotherapy (ICT) followed by concurrent CRT was compared with those after standard CRT alone in patients with locally advanced, unresectable head and neck cancer. PATIENTS AND METHODS: Between January 2007 and June 2009, 66 patients with advanced (stage III or IV) unresectable squamous cell carcinoma of the head and neck (oral cavity, oropharynx, hypopharynx, and larynx) were randomly assigned to two groups: one receiving two cycles of docetaxel, cisplatin, and 5-fluorouracil ICT followed by CRT with three cycles of cisplatin and one treated by CRT alone. Response rate, local tumor control (LTC), locoregional tumor control (LRTC), overall survival (OS), progression-free survival (PFS), and toxicity results were assessed. RESULTS: Three patients from the ICT + CRT group did not appear at the first treatment, so a total of 63 patients were evaluated in the study (30 ICT + CRT group and 33 CRT group). Three patients died of febrile neutropenia after ICT. The median follow-up time for surviving patients was 63 months (range 53-82 months). The rate of radiologic complete response was 63% following ICT + CRT, whereas 70% after CRT alone. There were no significant differences in the 3-year rates of LTC (56 vs. 57%), LRTC (42 vs. 50%), OS (43 vs. 55%), and PFS (41 vs. 50%) in the ICT + CRT group and in the CRT group, respectively. The rate of grade 3-4 neutropenia was significantly higher in the ICT + CRT group than in the CRT group (37 and 12%; p = 0.024). Late toxicity (grade 2 or 3 xerostomia) developed in 59 and 42% in the ICT + CRT and CRT groups, respectively. CONCLUSION: The addition of ICT to CRT did not show any advantage in our phase II trial, while the incidence of adverse events increased. The three deaths as a consequence of ICT call attention to the importance of adequate patient selection if ICT is considered.

RESUMO

OBJECTIVES/HYPOTHESIS: To determine whether blood transfusions are associated with adverse outcomes in patients with head and neck cancer (HNC) undergoing microvascular free tissue transfer. STUDY DESIGN: Retrospective cohort study. METHODS: The records of all patients who underwent free flaps for reconstruction after HNC resection from July 2007 through February 2013 at a single institution were reviewed. Rates of overall survival (OS), recurrence free survival (RFS), and postoperative wound infection were determined. Statistical analyses included Cox proportional hazards models and chi-square tests. RESULTS: Of 167 patients, 90 received 0 to 2 units of blood and 77 received ≥ 3. After controlling for age, preoperative hemoglobin, preoperative albumin, cancer stage, and adverse pathologic features, transfusion of ≥ 3 (versus 0 to 2) units was associated with poorer OS (P = 0.0006; hazard ratio [HR] = 2.96) and RFS (P = 0.003; HR = 2.35). The rates of wound infection in patients who received 0, 1, 2, or ≥ 3 units were 13.3%, 21.2%, 33.3%, and 31.2%, respectively. There was a statistically significant difference in wound infection rates between those patients receiving 0 to 1 versus ≥ 2 units (P = 0.04). CONCLUSIONS: Patients who receive ≥ 3 units of blood after free tissue transfer for HNC had a significantly increased risk of death after controlling for age, preoperative hemoglobin and albumin, cancer stage, and adverse pathologic features. Increased transfusions are also associated with higher wound infection rates. The increased tendency to transfuse free flap patients in order to maintain a threshold hematocrit may have a detrimental impact on survival and wound infections and should be revisited.

RESUMO

BACKGROUND: Epidemiological data on HNC are often reported aggregated despite their anatomical and histological heterogeneity. In Germany, few studies have analyzed incidence and mortality trends separately for specific anatomic sites. Furthermore, little is known about whether the incidence of HPV-associated tumour entities of the head and neck region has increased. METHODS: Based on cancer registry data from Rhineland-Palatinate from 2000 to 2009, age-standardized incidence and mortality rates were calculated for all HNC sites and localisation groups that might be HPV-associated according to the literature. Trends were analyzed by Joinpoint regression and reported as the annual percentage change (APC). RESULTS: Throughout the study period, 8 055 incident cases and 3 177 deaths were identified. The incidence rates of overall HNC increased among women (APC:+2.2%) and declined slightly among men (- 0.9%). Significantly increasing incidence rates among women were seen for tumours of the oral cavity (+2.7%) and the oropharynx (+3.6%). Among men, a significant decrease in incidence rates for tumours of the hypopharynx (-3.4%) and the larynx (-2.7%) are noteworthy. Cancers at HPV-associated sites showed increased incidence rates in men (+3.3%) and women (+4.3%). A decrease in mortality was found for tumours of the larynx in both sexes (-5.8% men,-9.1% women). CONCLUSIONS: A detailed analysis by localisation of HNC showed significant and often opposing trends for men and women regarding incidence and mortality.
