Increased likelihood of long-term gastrostomy tube dependence in head and neck cancer survivors without partners

Gastrostomy tubes: Fundamentals, periprocedural considerations, and best practices

Gastrostomy tube placement is a procedure that achieves enteral access for nutrition, decompression, and medication administration. Preprocedural evaluation and selection of patients is necessary to provide optimal benefit and reduce the risk of adverse events (AEs). Appropriate indications, contraindications, ethical considerations, and comorbidities of patients referred for gastrostomy placement should be weighed and balanced. Additionally, endoscopist should consider either a transoral or transabdominal approach is appropriate, and radiologic or surgical gastrostomy tube placement is needed. However, medical history, physical examination, and imaging prior to the procedure should be considered to tailor the appropriate approach and reduce the risk of AEs.

Patterns of recurrence after low-dose postoperative radiotherapy for head and neck squamous cell carcinoma

BACKGROUND

Postoperative chemoradiotherapy is recommended for patients with head and neck squamous cell carcinoma with positive margins or extracapsular extension at high risk of recurrence. However, high-dose radiotherapy in the head and neck region often causes severe acute and late radiation-related adversities. In our institution, the radiation dose has been relatively lower than that used in Western countries to reduce radiation-related toxicities. Therefore, in this study, we examined the treatment outcomes of low-dose postoperative chemoradiotherapy.

METHODS

The outcomes of 90 consecutive head and neck squamous cell carcinoma patients who received postoperative radiotherapy between June 2009 and December 2016 were retrospectively analyzed. All patients received postoperative three-dimensional conformal radiotherapy with or without concurrent systemic chemotherapy. The median patient age was 65 years. Concurrent chemoradiotherapy was administered at a total dose of 50.4 Gy in 28 fractions (daily fraction, 1.8 Gy). High-risk patients received 10.8 Gy of boost irradiation in six fractions. For radiotherapy alone, the irradiation dose was up to 54 Gy in 30 fractions and 64.8 Gy in 36 fractions for high-risk patients to increase the treatment intensity.

RESULTS

The median follow-up period was 40.5 months. The 3-year locoregional control and overall survival rates were 67.5% and 82.7%, respectively. A significantly higher proportion of patients with oral cavity carcinoma experienced locoregional failure (p = 0.004). The acute adverse events were mild, and the only late adverse event was grade 3 dysphagia (n = 3).

CONCLUSION

This study suggests that de-escalation of the postoperative radiation dose can potentially reduce the severe adverse events of irradiation in patients while ensuring its effectiveness. In patients with oral cavity carcinoma, it might be necessary to increase the radiation dose.

Free Flap Outcomes of Microvascular Reconstruction after Repeated Segmental Mandibulectomy in Head and Neck Cancer Patients

This is the first study to investigate the impact of a second fibula flap or a soft tissue flap combined with bridging plate for a repeated segmental mandibulectomy reconstruction on flap outcomes in head and neck cancer patients. A retrospective comparative analysis (2007–2016) of 61 patients who underwent a second segmental mandibulectomy was performed. 20 patients underwent a fibula flap reconstruction whereas 41 had a soft tissue flap and plate reconstruction. No significant difference was seen in the operative time, total hospital stay, flap loss, re-exploration rates, plate exposure rate, or recipient site infection rate. On multivariate analysis, patients reconstructed with a soft tissue flap and bridging plate (odds ratio (OR) 3.997; 95% confidence interval (CI), 1.046–15.280, p = 0.043) and complications developed in previous surgery (OR 4.792; 95% CI, 1.120–20.493, p = 0.035) were shown to be independent predictors of a prolonged nasogastric tube dependence. The utilization of a soft tissue flap with plate is associated with comparative results of acute complication rate within 1 week, recipient site infection rate, and plate exposure rate to free fibula flaps alone. Free fibula flaps may result in a decreased risk for prolonged tube dependence compared to free soft tissue flap reconstructions.

The experience of head and neck cancer survivorship (including laryngectomy): an integrated biopsychosocial model

PURPOSE OF REVIEW

The head and neck cancer (HNC) survivorship experience is unique among cancer populations. This review seeks to explore the HNC survivor experience associated with altered upper aerodigestive tract (UADT) function using principles of survivorship.

RECENT FINDINGS

HNC survivors experience complex physical, functional, and psychosocial challenges related to UADT dysfunction. Interventions need to address all of these dimensions being mindful of the survivor experience. Studies reveal related unmet needs of both HNC survivors and their family members. An expose of the HNC survivorship experience is timely since 2016/2017 contains the release of landmark position papers and guidelines in the field. These address the unique challenges faced by the HNC population, their management, and the triad psychosocial, functional, and physical survivor burden. Such developments will drive future care.

SUMMARY

The head and neck survivorship experience is characterized by complex changes with broad impact when examined in an experiential framework. HNC survivor care demands clinical excellence from multiple disciplines that are positioned to enact recent HNC guidelines and adopt survivorship principles. Future research in this population that explores experiential aspects of altered UADT function would be valuable in informing clinical practice. A biopsychosocial framework is presented for conceptualizing the HNC survivorship experience.

Development of Late Toxicities in Patients with Oral Tongue Cancer Treated with Surgical Resection and Adjuvant Radiation Therapy

Objectives

The late effects of RT are not well reported in patients with oral tongue cancer (OTC). This study reports the incidence of late effects and factors associated with the development of late effects in OTC patients.

Methods

Patients with OTC treated in our institution from 2003 to 2013 were evaluated. The association between RT doses, including mandible maximum and minimum doses and total 3D maximum dose, and late toxicity, defined as development of osteoradionecrosis (ORN), percutaneous endoscopic gastrostomy (PEG) tube dependence for >6 months after treatment, and narcotic dependency >6 months posttreatment were assessed using both univariate and multivariable (MV) analysis.

Results

Seventy-six patients with OTC (45% males and 55% females) were treated with definitive surgical resection followed by adjuvant RT. The median follow-up was 4.3 years. Combined late toxicities were reported in 38% of patients. Thirty-four percent of the patients had narcotic dependency and, 3.9% of the patients had ORN of the mandible. Thirteen percent of patients developed PEG tube dependency that was significantly associated with a higher 3D maximum radiation dose on univariate analysis (p < 0.01). On MV analysis, 3D maximum dose remained significantly associated with long-term PEG tube dependency (p = 0.05).

Conclusion

Patients with OTC treated with adjuvant RT are at significant risk for development of late toxicities. Increasing maximum dose is associated with long-term PEG tube dependence, and care should be taken to reduce the “hot spot” within radiation treatment plans as much as possible.

Comparison of Nutritional and Clinical Outcomes in Patients with Head and Neck Cancer Undergoing Chemoradiotherapy Utilizing Prophylactic versus Reactive Nutrition Support Approaches

BACKGROUND

The optimal method of tube feeding for patients with head and neck cancer remains unclear. A validated protocol is available that identifies high-nutritional-risk patients who would benefit from prophylactic gastrostomy tube placement. Adherence to this protocol is ultimately determined by clinical team discretion or patient decision.

OBJECTIVE

The study aim was to compare outcomes after adherence and nonadherence to this validated protocol, thus comparing a prophylactic and reactive approach to nutrition support in this patient population.

DESIGN

We conducted a prospective comparative cohort study. Patients were observed during routine clinical practice over 2 years.

PARTICIPANTS/SETTING

Patients with head and neck cancer having curative-intent treatment between August 2012 and July 2014 at a tertiary hospital in Queensland, Australia, were included if assessed as high nutrition risk according to the validated protocol (n=130). Patients were grouped according to protocol adherence as to whether they received prophylactic gastrostomy (PEG) per protocol recommendation (prophylactic PEG group, n=69) or not (no PEG group, n=61).

MAIN OUTCOME MEASURES

Primary outcome was percentage weight change during treatment. Secondary outcomes were feeding tube use and hospital admissions.

STATISTICAL ANALYSIS PERFORMED

Fisher's exact, χ², and two sample t tests were performed to determine differences between the groups. Linear and logistic regression were used to examine weight loss and unplanned admissions, respectively.

RESULTS

Patients were 88% male, median age was 59 years, with predominantly stage IV oropharyngeal cancer receiving definitive chemoradiotherapy. Statistically significantly less weight loss in the prophylactic PEG group (7.0% vs 9.0%; P=0.048) and more unplanned admissions in the no PEG group (82% vs 75%; P=0.029). In the no PEG group, 26 patients (43%) required a feeding tube or had ≥10% weight loss.

CONCLUSIONS

Prophylactic gastrostomy improved nutrition outcomes and reduced unplanned hospital admissions. Additional investigation of characteristics of patients with minimal weight loss or feeding tube use could help refine and improve the protocol.

Gastrostomy in head and neck cancer: current literature, controversies and research

PURPOSE OF REVIEW

This article explores the literature on the role of gastrostomy tube feeding use in the management of head and neck cancer, with special attention to its indications, timing of insertion, advantages, complications and quality of life issues.

RECENT FINDINGS

The current guidelines in place across different countries and two ongoing randomized controlled trials are discussed in detail, and placed in the context of current evidence.

SUMMARY

There remains a lack of consensus about when and which enteral feeding routes (gastrostomy or nasogastric tube) should be used and controversy about the long-term effects on swallowing function as well as quality of life for patients. Local guidelines should be used or generated to guide practice or patients enrolled into existing trials until higher level evidence is generated.

Impact of feeding tubes on prospective functional outcomes in patients with locally advanced head and neck cancer undergoing radiation therapy

PURPOSE

The optimal timing of enteral feeding tube (FT) insertion during radiation therapy for head and neck cancer remains controversial. This study compares prospectively collected functional outcomes for prophylactic versus reactive insertion.

METHODS AND MATERIALS

Patients undergoing primary radiation therapy for stage III-IV head and neck cancer between 2004 and 2009 underwent functional outcome assessment at baseline and 3, 6, 12, 24, and 36 months posttreatment. Instruments included the Royal Brisbane Hospital Outcome Measure for Swallowing, Performance Status Scale for Head and Neck Cancer Patients, and modified Edmonton Symptom Assessment Scale. Multivariable regression analysis was conducted to determine the impact of FT use on functional outcomes.

RESULTS

A total of 178 patients were assessed with a median follow-up of 36.4 months. Use of an FT was prophylactic in 92 and reactive in 24; no tube was used in 62 patients. Compared with prophylactic placement, reactive FT use was not associated with worse function for Performance Status Scale for Head and Neck Cancer Patients Normalcy of Diet for soft foods (adjusted odds ratio [AOR] 1.16, P = .85) or Eating in Public (AOR 1.87, P = .31). Similarly, there were no differences in the Royal Brisbane Hospital Outcome Measure for Swallowing for modified diet (AOR 1.27, P = .7) or FT dependence (AOR 3.01, P = .2).

CONCLUSIONS

There were no significant differences in long-term swallowing function between patients who received a prophylactic versus reactive FT.

The effect of prophylactic percutaneous endoscopic gastrostomy (PEG) tube placement on swallowing and swallow-related outcomes in patients undergoing radiotherapy for head and neck cancer: a systematic review

Patients undergoing radiotherapy for head and neck cancer (HNC) often experience malnutrition and dehydration during treatment. As a result, some centres place PEG tubes prophylactically (pPEG) to prevent these negative consequences. However, recent research has suggested that pPEG use may negatively affect swallowing physiology, function and/or quality of life, especially in the long term. The purpose of this study was to systematically review the literature on pPEG use in HNC patients undergoing radiotherapy and to determine its impact on swallowing-related outcomes. The following electronic databases were searched for all relevant primary research published through February 24, 2014: AMED, CINAHL, the Cochrane Library, Embase, Healthstar, Medline, and PsycINFO. Main search terms included HNC, radiotherapy, deglutition disorders, feeding tube(s), and prophylactic or elective. References for all accepted papers were hand searched to identify additional relevant research. Methodological quality was assessed using Cochrane's Risk of Bias. At all levels, two blinded raters provided judgments. Discrepancies were resolved by consensus. The search retrieved 181 unique citations. Twenty studies met our inclusion criteria. Quality assessment revealed that all studies were at risk for bias due to non-randomized sampling and unreported or inadequate blinding. Ten studies demonstrated selection bias with significant baseline differences between pPEG patients and controls. Results regarding the frequency and severity of dysphagia and swallowing-related outcomes were varied and inconclusive. The impact of pPEG use on swallowing and swallowing-related outcomes remains unclear. Well-controlled, randomized trials are needed to determine if pPEG places patients at greater risk for developing long-term dysphagia.

Outcomes measurement in patients with head and neck cancer

Outcomes research is defined as clinical and population-based research that investigates the results of healthcare practices or interventions through the filter of the benefit to the patient and other stakeholders. Outcomes research is an increasingly important field or research, because of the pressing need for evidence-based information that can be used to make better informed health and healthcare decisions, and define desired health care practices in the current era of healthcare reform. This article will review the head and neck cancer (HNCA) outcomes literature published in the past year, with a focus on studies evaluating treatment and survival, short-term and long-term complications, and quality of life (QOL).

Toxicities and costs of placing prophylactic and reactive percutaneous gastrostomy tubes in patients with locally advanced head and neck cancers treated with chemoradiotherapy

BACKGROUND

We compared dependence rates, complications, toxicities, and costs associated with prophylactic versus reactive percutaneous endoscopic gastrostomy (PEG) tube placement.

METHODS

One hundred ninety-three patients with locally advanced head and neck squamous cell carcinoma treated with concurrent chemoradiotherapy were retrospectively reviewed.

RESULTS

The 1-year and 2-year actuarial PEG tube dependence rate of the entire cohort was 24% and 13%, respectively. There was no difference in the PEG tube dependence rates between those placed prophylactically versus reactively. Patients who received a PEG tube reactively had a significantly higher stricture rate (p = .03) and aspiration rate (p < .001) compared to the prophylactic group. There were significantly fewer hospitalizations in the prophylactic group compared to the reactive group (p = .003). When accounting for both PEG placement and hospitalizations, the prophylactic approach was found to be more cost effective.

CONCLUSION

PEG tubes placed prophylactically were associated with lower rates of strictures, aspirations, hospitalizations, and costs compared to those placed reactively.

Patterns of prophylactic gastrostomy tube placement in head and neck cancer patients: a consideration of the significance of social support and practice variation

OBJECTIVES/HYPOTHESIS

The purpose of this study was to examine factors associated with prophylactic placement of feeding tubes in head and neck cancer patients receiving radiation therapy as a part of treatment using multilevel models that account for patient-, physician-, and institution-level sources of variation.

STUDY DESIGN

A retrospective analysis using binary logistic regression and hierarchical linear models was run to evaluate independent predictors of prophylactic feeding tube placement.

METHODS

Surveillance, Epidemiology, and End Results-Medicare data were used. Head and neck cancer patients diagnosed with locoregionally advanced stage disease from 2000 to 2005 were included in this study (N = 8,306).

RESULTS

Across all models, prophylactic gastrostomy tube placement was found to be more likely in patients who had cancer of the larynx or oropharynx compared with those with cancer of the nasopharynx or oral cavity; who had regional instead of local cancer; who did not receive surgery as a part of treatment, but did receive chemotherapy; and who were divorced, separated, or widowed. Additionally, although practice variation was observed to occur, its overall contribution in predicting prophylactic gastrostomy tube placement was minimal.

CONCLUSIONS

As health care enters an era of patient-centered care, further investigation of the potential role of social support (or lack of social support) in influencing treatment decisions of head and neck cancer patients and providers is warranted.
