Multidisciplinary management of head and neck cancer: First expert consensus using Delphi methodology from the Spanish Society for Head and Neck Cancer (part 2)

Predict nutrition-related adverse outcomes in head and neck cancer patients undergoing radiotherapy: A systematic review

BACKGROUND

Acute nutrition-related adverse outcomes are common in head and neck cancer patients undergoing radiotherapy. Predictive models can assist in identifying high-risk patients to enable targeted intervention. We aimed to systematically evaluate predictive models for predicting severe acute nutritional symptoms, insufficient intake, tube feeding, sarcopenia, and weight loss.

METHODS

We searched PubMed, Web of Science, EBSCO, Embase, WanFang, CNKI, and SinoMed. We selected studies developing predictive models for the aforementioned outcomes. Data were extracted using a predefined checklist. Risk of bias and applicability assessment were assessed using the Prediction model Risk of Bias Assessment Tool. A narrative synthesis was conducted to summarize the model characteristics, risk of bias, and performance.

RESULTS

A total of 2941 studies were retrieved and 19 were included. Study outcome measure were different symptoms (n = 11), weight loss (n = 5), tube feeding (n = 3), and symptom or tube feeding (n = 1). Predictive factors mainly encompassed sociodemographic data, disease-related data, and treatment-related data. Seventeen studies reported area under the curve or C-index values ranging from 0.610 to 0.96, indicating moderate to good predictive performance. However, candidate predictors were incomplete, outcome measures were diverse, and the risk of bias was high. Most of them used traditional model development methods, and only two used machine learning.

CONCLUSIONS

Most current models showed moderate to good predictive performance. However, predictors are incomplete, outcome are inconsistent, and the risk of bias is high. Clinicians could carefully select the models with better model performance from the available models according to their actual conditions. Future research should include comprehensive and modifiable indicators and prioritize well-designed and reported studies for model development.

Multidisciplinary tumor board for head and neck cancer from the perspective of medical oncologists-optimizing its effectiveness

Head and neck cancer (HNC) treatment is becoming increasingly multidisciplinary, and patient characteristics vary. Therefore, a multidisciplinary tumor board (MTB) is essential in clinical practice. This review provides insights into the benefits and tips for improving head and neck MTB from the perspective of medical oncologists. The MTB is a platform to discuss the optimal application of the standard of care to each case, reach a consensus, and establish a recommendation to support patients' decision-making. A productive and educational MTB also provides an opportunity to share information on ongoing clinical trials with physicians. Case presentations should be systematic to discuss all new and challenging cases before, during, and after the treatment. Human resource development, particularly of head and neck medical oncologists, is crucial. The type of multidisciplinary network between medical staff and the extent of patient intervention differs among MTB teams. Subsequently, a virtual MTB can establish a medical network between institutions that will contribute to the equalization and centralization of head and neck oncologic care.

Defining a Standard Set of Health Outcomes for Patients With Squamous Cell Carcinoma of the Head and Neck in Spain

Purpose

A systematic, standardized collection of health outcomes during patient treatment and follow-up, relevant from the perspective of all stakeholders, is a crucial step toward effective and efficient disease management. This project aimed to define a standard set of health outcomes for patients with squamous cell carcinoma of the head and neck (SCCHN).

Methods

The project was led and coordinated by a scientific committee (SC). It comprised: (1) a literature review (to identify variables used during SCCHN management); (2) 1^st-SC meeting (to select the variables for presentation during nominal groups-NG); (3) five NG (n=42 experts) and four interviews with patients (to reach consensus on the variables for inclusion); and (4) final-SC meeting (to review the results of NG ensuring consensus on the variables where consensus was not reached).

Results

Experts agreed to include the following variables in the standard set: treatment-related (treatment intent and type, response to treatment, treatment toxicity/complication, treatment completion), degree of health (performance status, patient-reported health status, pain, dysphonia, feeding and speech limitations, body image alteration, tracheotomy), survival (overall and progression-free survival, cause of death), nutritional (weight, nutritional intervention), other variables (smoking status, alcohol consumption, patient satisfaction with aftermath care, employment status), and case-mix variables (demographic, tumor-related, clinical and nutritional factors).

Conclusions

This project may pave the way to standardizing the collection of health outcomes in SCCHN and promote the incorporation of patients’ perspective in its management. The information provided through the systematic compilation of this standard set may define strategies to achieve high-quality, patient-centered care.

Risk stratified follow up for head and neck cancer patients - An evidence based proposal

Head and neck squamous cell carcinoma (HNSCC) has a significant impact on patients' quality of life and treatment can be associated with severe morbidity. Following completion of treatment, patients are followed up in order to detect potentially salvageable recurrences and to manage long-term toxicities. In recent years, a growing interest has been given to risk stratified follow-up interventions to prevent and detect recurrences and manage treatment toxicities in other tumour sites as well as to transfer some of that care to community services. We review the literature for HNSCC and propose a risk stratified follow up protocol to address these issues and assist clinicians in decision making. A shift in patterns of care is suggested in order to provide a basis to improve care for HNSCC patients after complete response to primary treatment.

Benefits and Limitations of a Multidisciplinary Approach in Cancer Patient Management

Over the years, a growing body of literature has confirmed as beneficial the implementation of a multidisciplinary approach in the so-often-intricate scenario of cancer patients' management. Together with the consolidation of tumor-board experience in clinical practice, certain aspects have emerged as controversial and a source of current debate. In this systematic literature review, we focused our attention on the impact of multidisciplinary tumor boards, assessing benefits and limitations as a result of the dissemination of such approaches. On the bright side, adherence to clinical guidelines, treatment outcomes, and overall improvement in decision-making processes have been recognized as advantages. On the other side, our analysis highlights a few limitations that should be taken into account to optimize cancer patients' management. Of note, some issues, such as costs, legal responsibility, geographic barriers, and treatment delays, have yet to be resolved. In order partly to address this matter, software platforms and novel methods of computational analysis may provide the needed support. Therefore, the aim of our analysis was to describe the multidisciplinary approach in cancer care in terms of adherence to clinical guidelines, treatment outcomes, and overall improvement in decision-making processes through a systematic review of the literature.

Global treatment patterns and outcomes among patients with recurrent and/or metastatic head and neck squamous cell carcinoma: Results of the GLANCE H&N study

OBJECTIVES

Given a lack of universally-accepted standard-of-care treatment for patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), study objectives were to assess treatment utilization and survival outcomes for R/M HNSCC in the real-world setting.

MATERIALS AND METHODS

A multi-site retrospective chart review was conducted in Europe (Germany, United Kingdom, Italy, Spain), Asia Pacific (Australia, South Korea, Taiwan), and Latin/North America (Brazil and Canada) to identify patients who initiated first-line systemic therapy for R/M HNSCC between January 2011 and December 2013. Patients were followed through December 2015 to collect clinical characteristics, treatment and survival data.

RESULTS

Among 733 R/M HNSCC patients across 71 sites, median age was 60 years (inter-quartile range 54-67), 84% male, and 70% Eastern Cooperative Oncology Group performance status 0-1; 32% had oral cavity and 30% oropharyngeal cancers. The most common first-line regimen across all countries consisted of platinum-based combinations (73%), including platinum + 5-fluorouracil (5-FU) (26%), cetuximab + platinum ± 5-FU (22%), or taxane + platinum ± 5-FU (16%). However, use of different platinum-based combinations varied substantially; administration of cetuximab + platinum ± 5-FU was frequent in Italy (81%), Germany (46%) and Spain (38%), whereas use in other countries was limited. Median follow-up was 22.6 months (95% confidence interval [CI]: 21.5-24.6 months). Median real-world overall survival was only 8.0 months (95% CI: 7.0-8.0), with one-year survival reaching only 30.9% (95% CI: 27.5-34.3).

CONCLUSION

Systemic therapies used in clinical practice for patients with R/M HNSCC vary substantially across countries. Prognosis remains poor in this patient population, highlighting the need for newer, more efficacious treatments.

Outcome and toxicity of intensity-modulated radiotherapy with simultaneous integrated boost in patients with pharyngo-laryngeal cancer

PURPOSE

The present work aims at evaluating intensity-modulated radiation therapy with simultaneous integrated boost (IMRT-SIB) in squamous cell carcinomas (SCC) of the larynx and hypopharynx.

METHODS/PATIENTS

We performed a single institutional retrospective analysis on 116 pharyngo (29%)-laryngeal (71%) SCC patients (93% male) treated with IMRT-SIB to 66-69.96 Gy in 33 fractions between 2008 and 2016. Those who underwent surgery (54%) received adjuvant radiation of 66 Gy at 2 Gy/fraction to the surgical bed. 16 patients (14%) were treated for a local recurrence after prior surgery. High-risk lymph node regions received 59.4 Gy at 1.8 Gy/fraction and low risk regions 54.12 Gy at 1.64 Gy/fraction. The median age was 60 years and 95% of patients had an ECOG performance status 0-2. Most had advanced stage disease (III 22%, IV 74%). Chemotherapy was delivered in 74% of cases.

RESULTS

Median follow-up was 32 months. Two and three-year overall survival for all patients was 87% and 82%, respectively. There were 28 (24%) locoregional recurrences and 19 (16%) distant failures. Grade 3 mucositis, dermatitis, and xerostomy were observed in 12%, 10%, and 3%, respectively. A longer IMRT-SIB overall treatment time was associated with a higher risk of mortality (HR 1.09, CI 1.01-1.17, P = 0.02). Postoperative IMRT-SIB associated with a significantly lower risk of any recurrence (HR 0.34, CI 0.18-0.64, P = 0.001) and higher local control (HR 0.06, CI 0.01-0.24, P < 0.01). Additionally, it associated with a lower risk of mucositis (P = 0.029) compared with definitive radio (chemo) therapy.

CONCLUSIONS

IMRT-SIB is a safe and feasible radiation treatment technique for pharyngo-laryngeal SCC patients with a tolerable acute toxicity profile.

Bloodstream infection in patients with head and neck cancer: a major challenge in the cetuximab era

PURPOSE

To assess the impact of bloodstream infection (BSI) in patients with head and neck cancer (HNC) in the cetuximab era.

METHODS

We prospectively analysed the epidemiology, microbiology and outcomes of 51 BSI episodes occurring in 48 patients with HNC (2006-2017). We performed a retrospective matched-cohort study (1:2) to determine the risk factors for BSI. Finally, we compared patients who died with those who survived to identify risk factors for mortality.

RESULTS

The most frequent HNC localization was the oropharynx (43%), and pneumonia was the most frequent source (25%). Gram-positive BSI occurred in 55% cases, mainly due to Streptococcus pneumoniae (21%), and among Gram-negatives, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae were the most frequent. Hypoalbuminemia (OR 8.4; 95% CI, 3.5-19.9), previous chemotherapy (OR, 3.2; 95% CI, 1.3-7.4) and cetuximab therapy (OR, 2.8; 95% CI, 1.6-6.7) were significant risk factors for BSI. Patients with BSI had a higher overall case-fatality rate than patients without BSI (OR, 4.4; 95% CI, 1.7-11.8). Hypoalbuminemia was an independent risk factor for the early (7 day) and overall (30 day) case-fatalities, with ORs of 0.8 (95% CI, 0.6-0.9) and 0.8 (95% CI, 0.7-0.97), respectively. The presence of comorbidities (OR, 7; 95% CI, 1.4-34) was also an independent risk factor for overall case-fatality.

CONCLUSIONS

BSI causes high mortality in patients with HNC and is most often secondary to pneumonia. It occurs mainly among patients with hypoalbuminemia who receive treatment with cetuximab or chemotherapy. The development of BSI in patients with HNC impairs their outcome, especially in the presence of hypoalbuminemia and comorbidities.
