Adequacy of nutritional support using computed tomography (CT) in patients with head and neck cancer (HNC) during chemo-radiotherapy (CRT).

We assessed forty HNC patients receiving treatment with curative intent. Specific quantitative muscle and fat changes were evaluated using CT. Nutrition support was provided according to ESPEN guidelines, with adjusted body weight (ABW) in overweight/obese patients used to define their nutritional targets. Linear regression models were used to evaluate clinical predictors of tissue loss. Mean overall losses were body weight (-10.5%), and CT-defined muscle (-8.4%) and fat mass (-24.8%), p < 0.001. A subset of 20 patients had high muscle loss (-14.7%) with concurrent negative energy balance as reflected by considerable fat loss (-29.7%); those tended to have higher baseline body mass index (26.2 vs. 23.3 kg/m2, p = 0.063). In multivariate regression, only ABW independently predicted muscle loss (p < 0.001) and fat loss (p = 0.002). Nutrition support according to guidelines was appropriate for a subset of patients. ABW use to set nutrition targets in overweight/obese patients would appear to be insufficient, based on large tissue losses.

The Multidisciplinary Team (MDT) Approach and Quality of Care.

The core function of a multidisciplinary team (MDT) is to bring together a group of healthcare professionals from different fields in order to determine patients' treatment plan. Most of head and neck cancer (HNC) units are currently led by MDTs that at least include ENT and maxillofacial surgeons, radiation and medical oncologists. HNC often compromise relevant structures of the upper aerodigestive tract involving functions such as speech, swallowing and breathing, among others. The impairment of these functions can significantly impact patients' quality of life and psychosocial status, and highlights the crucial role of specialized nurses, dietitians, psycho-oncologists, social workers, and onco-geriatricians, among others. Hence, these professionals should be integrated in HNC MDTs. In addition, involving translational research teams should also be considered, as it will help reducing the existing gap between basic research and the daily clinical practice. The aim of this comprehensive review is to assess the role of the different supportive disciplines integrated in an MDT and how they help providing a better care to HNC patients during diagnosis, treatment and follow up.

Management of radiodermatitis associated with cetuximab in squamous cell carcinomas of the head and neck.

The objective of this review is to report to the medical community the most recent knowledge on prevention and management of dermatitis with the use of cetuximab simultaneously with radiotherapy in the treatment of squamous cell carcinomas of the head and neck. A review was conducted in PubMed of English language publications between 2010 and 2015. The search employed the terms 'skin toxicity', 'radiodermatitis', 'cetuximab', 'radiotherapy', and 'head and neck cancer'. Data related to the classification and management of dermatitis, associated with cetuximab with concomitant radiotherapy (n = 22), were critically reviewed. We conclude that dermatitis associated with bioradiotherapy is a predictable, treatable, and reversible event that does not affect administration of therapy or its clinical outcome when treated appropriately.

Late toxicity after radical treatment for locally advanced head and neck cancer.

BACKGROUND: Multimodal treatment for locally advanced head and neck carcinomas (LAHNC) has been reported to improve survival. However, it is less clear to what extent this survival gain is given at the expense of an impact on the quality of life of our patients. Our aim is to analyze the ongoing late toxic effects among long survivors, to determine how much these impairments affect their QoL, and if there is any factor that clearly impacts on this toxicity. METHODS: 152 Patients diagnosed with LAHNC were treated radically in our clinical practice, either with concomitant chemoradiotherapy or bioradiotherapy, with or without induction chemotherapy. We prospectively assessed these patients' treatment-related late toxicities according to the Radiation Therapy Oncology Group scoring system, and patients answered a QoL question to subjectively evaluate the degree of impact caused by these sequelae in their daily life. Multivariate logistic regressions were performed to detect factors that could influence in toxicity. RESULTS: 21.9% Patients experienced grade 3-4 toxicity. Concomitant chemoradiation with cisplatin was found to be a risk factor of moderate and severe late toxicity compared to concomitant cetuximab in the adjusted analysis by RT fractionation. OR for moderate toxicity 0.292 (CI: 0.125-0.680, p=0.004); OR for severe toxicity: 0.299 (CI: 0.0909-0.999, p=0.05). Induction chemotherapy was found to be a protective factor for moderate late toxicity compared to concomitant treatment alone. CONCLUSION: Patients treated with concomitant chemoradiation with cisplatin have significantly more late toxicity compared to bioradiotherapy, whereas induction chemotherapy prevents from developing moderate late toxicity.

Rapid palliation of symptoms with platinum-based chemotherapy plus cetuximab in recurrent oral cancer: a case report.

BACKGROUND: Symptom control is an important consideration in the choice of treatment for patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Patients who demonstrate objective tumour responses to platinum-based chemotherapy are more likely to have symptom relief than those who do not have such responses. A phase III trial (EXTREME) showed that adding the epidermal growth factor receptor (EGFR)-targeting IgG1 monoclonal antibody cetuximab to first-line platinum-based chemotherapy significantly prolongs progression-free and overall survival and increases response rate compared with platinum-based chemotherapy alone. We report here the case of a 60-year old female with recurrent squamous cell carcinoma of the gum who had rapid palliation of symptoms and reduction of facial disease mass following treatment with a combination of carboplatin/5-fluorouracil (5-FU) and cetuximab. CASE PRESENTATION: The patient was diagnosed with T4N0 M0 disease of the oral cavity in November 2006 and underwent surgery, with R0 resection, followed by adjuvant radiotherapy and concomitant cisplatin chemotherapy. Around 3 months later, the disease recurred and the patient had severe pain (9/10 on a visual pain scale), marked facial oedema and a palpable facial mass of 89 mm. The patient received 4 21-day cycles of carboplatin (AUC 5), 5-FU (1,000 mg/m2/day for 4 days) and cetuximab (400 mg/m2 initial dose followed by subsequently weekly doses of 250 mg/m2), with continuation of cetuximab monotherapy at the end of this time, and pain relief with topical fentanyl and oral morphine. After 7 days of treatment, pain had reduced to 2/10, with discontinuation of morphine after 4 days, and the facial mass had reduced to 70 mm. After 2 cycles of treatment, the facial mass had decreased to 40 mm. After 3 cycles of treatment, pain and facial oedema had resolved completely and a cervical computed tomography scan showed a marked reduction in tumour mass. Cetuximab monotherapy was continued uninterrupted for 7 months. CONCLUSION: This case illustrates the rapid reduction of tumour mass and disease-associated pain and oedema that can be achieved with a combination of platinum-based chemotherapy and cetuximab in recurrent and/or metastatic SCCHN.
