Oral cancers: supportive care issues

The impact of pretreatment symptom burden on long-term quality of life following head and neck radiation: A prospective longitudinal study

BACKGROUND

This study characterized the impact of baseline symptom burden on long-term quality-of-life in patients receiving head and neck radiation therapy (RT).

METHODS

The Vanderbilt Head and Neck Symptom Survey was collected prior to head and neck RT and at follow-up visits. Responses were divided into symptom clusters of toxicities and scored from 0 (asymptomatic) to 10 (severe). Patients with responses at baseline and 1-year or 2-year follow-up were stratified by scores ≤1 or >1 and compared using the Mann-Whitney U-test.

RESULTS

At 1-year follow-up (n = 75), patients with higher baseline scores had greater symptom burden for every cluster except in taste/smell. At 2-year follow-up (n = 47), patients with higher baseline scores had greater symptom burden for every cluster except in nutrition, dry mouth, trismus, neck tightness, and hearing.

CONCLUSION

The Vanderbilt Head and Neck Symptom Survey demonstrated a relationship between baseline symptom burden and long-term quality-of-life and might be useful as a screening tool.

Impact of Clustering Oral Symptoms in the Pathogenesis of Radiation Caries: A Systematic Review

Radiation-related caries (RRC) is a disease with a high potential for destruction of the dentition, which impairs quality of life in head-and-neck (HN) cancer (HNC) patients who undergo radiotherapy. In light of the recently described “clustering of oral symptoms theory,” the present systematic review (PROSPERO CRD42019132709) aims to assess HN and gastrointestinal (GI) symptom clusters among HNC patients and discusses how these indirect effects of cancer therapy play a pivotal role in the pathophysiology of RRC. The search was performed at PubMed, Scopus, and Embase and resulted in 11 studies that met the inclusion criteria. Data extraction was performed with respect to the presence of HN/GI symptom clusters among HNC patients. The methodological data of the studies included were assessed using the MAStARI and GRADE instruments. The most prevalent reported HN symptoms were dysphagia, xerostomia, and pain. Taste alterations and fatigue were also commonly reported by the patients. Loss of appetite and weight loss were regularly reported in the studies, as well as nausea and vomiting. The results of the present study suggest that HNC treatment generates clusters of oral symptoms, leading to dietary changes, impaired oral hygiene, enamel fragility, and a highly cariogenic oral environment, which may impact the risk for RRC. A better understanding of oral symptom clustering could be of considerable clinical significance for the oral health and quality of life of HNC patients. Therefore, contemporary protocols of RRC prevention must take this broader treatment scenario of symptom clusters such as oral side effects into account.

The Effects of a Supportive Care Program on the Posttraumatic Stress Symptoms of Patients With Oral Cancer After Surgery

This study aimed to estimate the effects of a supportive care program on the posttraumatic stress symptoms (PTSSs) of patients with oral cancer after surgery. Participants were divided into two groups. Outcome measurements included the Chinese version of the Davidson trauma scale to examine PTSSs at a clinical follow-up 1 week (T0), 1 month (T1), and 3 months (T2) after hospital discharge. The results indicated that the frequency and severity mean scores of PTSSs for the two groups at T0 were significantly higher than those at T1 and T2. Both the groups and times were significantly different; moreover, the supported group's PTSS score decreased more than that of the nonsupported group. These findings supported the effects of the supportive care program. Health care staff should be aware of the PTSS status of patients with oral cancer who undergo surgery and consider these issues in combination with patients' discharge care plans.

A critical assessment of oral care protocols for patients under radiation therapy in the regional University Hospital Network of Madrid (Spain)

BACKGROUND

This research was aimed to critically evaluate, under the light of the available scientific evidence, the oral care protocols recommended by different hospitals in head and neck cancer (HNC) patients under radiation therapy.

MATERIAL AND METHODS

A questionnaire requesting all the relevant information for the oral care of these patients was sent to the 9 University Hospitals in Madrid. The answers were categorized and analyzed. In addition, an electronic search was conducted to identify the most relevant papers (systematic reviews [SR] and randomized clinical trials [RCTs]) assessing oral care protocols for patients treated for HNC with radiation therapy.

RESULTS

Eight out of nine centers answered the questionnaire and the retrieved information was tabulated and compared. These recommendations were analyzed by a computerized search on MEDLINE and the Cochrane Oral Health Collaboration Database. The results of the analysis clearly shown a great heterogeneity, in terms of oral health care protocols, regarding the management of irradiated patients (for HNC) within the Hospitals of Madrid region. In addition, some of the recommendations lack solid scientific support.

CONCLUSIONS

The present survey revealed that the recommendations provided by the different hospitals were clearly different. The available evidence, supported by SR and RCTs, suggested the need of an oral assessment before cancer treatment, in order to prevent and treat dental pathologies and avoiding potential complications; during cancer treatment, it is relevant monitoring the patient in order to decrease the severity of the side effects, and to avoid any tooth extraction or surgery and special attention should be paid to mucositis, xerostomia and candidiasis; after cancer treatment, the following are relevant aspects: the risk of osteoradionecrosis, trismus, caries and the risks associated to dental implants.

KEY WORDS

Head and neck cancer, supportive care in cancer, radiotherapy complications, management and oral care on cancer treatment.

Translation and cross-cultural adaptation into Brazilian Portuguese of the Vanderbilt Head and Neck Symptom Survey version 2.0 (VHNSS 2.0) for the assessment of oral symptoms in head and neck cancer patients submitted to radiotherapy

INTRODUCTION

Patients submitted to radiotherapy for the treatment of head and neck cancer have several symptoms, predominantly oral. The Vanderbilt Head and Neck Symptom Survey version 2.0 is an American tool developed to evaluate oral symptoms in head and neck cancer patients submitted to radiotherapy.

OBJECTIVE

The aim of the present study was to translate the Vanderbilt Head and Neck Symptom Survey version 2.0 into Brazilian Portuguese and cross-culturally adapt this tool for subsequent validation and application in Brazil.

METHODS

A method used for the translation and cultural adaptation of tools, which included independent translations, synthesis of the translations, back-translations, expert committee, and pre-test, was used. The pre-test was performed with 37 head and neck cancer patients, who were divided into four groups, to assess the relevance and understanding of the assessed items. Data were submitted to descriptive statistical analysis.

RESULTS

The overall mean of the content validity index was 0.79 for semantic and idiomatic equivalence, and it was higher than 0.8 for cultural and conceptual equivalence. The cognitive interview showed that patients were able to paraphrase the items, and considered them relevant and easily understood.

CONCLUSION

The tool was translated and cross-culturally adapted to be used in Brazil. The authors believe this translation is suited for validation.

The Vanderbilt Head and Neck Symptom Survey Brazilian Portuguese version 2.0 (VHNSS 2.0): psychometric properties for patients with head and neck cancer who have undergone radiotherapy

BACKGROUND

Patients who undergo radiotherapy to treat head and neck cancer can present with several symptoms, including oral ones. The symptoms are usually assessed using instruments to evaluate quality of life. However, these instruments do not really assess oral health outcomes and their functional implications. The VHNSS 2.0 instrument was developed to be used with head and neck cancer patients, and has recently been translated and culturally adapted to be used in Brazil. The purpose of the study was to evaluate the psychometric properties of the VHNSS 2.0 Brazilian Portuguese version.

METHODS

Three assessment instruments, the Brazilian Portuguese versions of EORTC QLQ-C30, EORTC H&N 35 and VHNSS 2.0, were answered by 241 head and neck cancer patients, of whom 47 were submitted to the test retest in 5-16 days. The construct validity was assessed through convergent validation (assuming correlations between VHNSS 2.0 and EORTC), and known group analysis (radiotherapy time, site of tumor, staging and surgery). Reliability was evaluated by means of Cronbach's alpha and test retest using the intraclass correlation coefficient.

RESULTS

241 head and neck cancer patients, median age 58.8, were included in this study. Hypothesized correlations were confirmed, the comparison among the groups showed differences in most of the domains. Reliability for the domains of swallowing solids, dry mouth, mouth pain, mucus, voice, pain and taste/smell presented Cronbach's alpha values from 0.858 to 0.735 and for the domains of nutrition, swallowing liquids and teeth, 0.618, 0.620 and 0.670 respectively. The test-retest reliability, for the domains of the VHNSS 2.0, measured using intraclass correlation coefficient, ranged from 0.372 to 0.854.

CONCLUSION

The VHNSS 2.0 Brazilian Portuguese version presented good results for the convergent validation and known-group analyses. It also showed reliability for the Cronbach´s alpha and test retest for most domains.

Expertise regarding dental management of oral cancer patients receiving radiation therapy among Western Australian dentists

OBJECTIVES

Dental care forms an important part of the multidisciplinary management of oral cancer patients. The aim of this study was to examine actual and self-perceived knowledge and clinical expertise regarding dental management of oral cancer patients receiving radiation therapy among Western Australian general dentists.

MATERIALS AND METHODS

An invitation to participate in a web-based questionnaire was emailed to 1095 dentists registered with the Australian Dental Association (ADA), WA branch. To assess dentists' knowledge and expertise, actual and perceived knowledge was investigated. Information regarding type of practice, practice location, year of graduation and number of oral cancer patients treated in the preceding 12 months was also obtained.

RESULTS

One hundred and ninety one dentists responded to the survey. General dentists who took part in the study appeared to possess some knowledge regarding dental management of oral cancer patients treated with radiation therapy. The majority of responders however identified deficiencies in their knowledge and willingness to participate in continuing education programs.

CONCLUSION

In view of the rising incidence of oral cancer in Western Australia, efforts should be made to provide more clinically relevant training to dentists in this area.
