Quality of life measurements of speech in the head and neck cancer patient population

The level of association between functional performance status measures and patient-reported outcomes in cancer patients: a systematic review

PURPOSE

The process of assessing patient symptoms and functionality using patient-reported outcomes (PROs) and functional performance status (FPS) is an essential aspect of patient-centered oncology research and care. However, PRO and FPS measures are often employed separately or inconsistently combined. Thus, the purpose of this study was to conduct a systematic review of the level of association between PRO and FPS measures to determine their differential or combined utility.

METHODS

A systematic search was conducted using five databases (1966 to February 2014) to identify studies that described an association between PRO and FPS. Studies were excluded if they were non-cancer specific, did not include adults aged 18 or older, or were review articles. Publications were selected for review by consensus among two authors, with a third author arbitrating as needed.

RESULTS

A total of 18 studies met inclusion criteria. FPS was primarily assessed by clinicians using the ECOG Performance Status or Karnofsky Performance Status measures. PROs were captured using a variety of measures, with numerous domains assessed (e.g., pain, fatigue, and general health status). Concordance between PROs and FPS measures was widely variable, falling in the low to moderate range (0.09-0.72).

CONCLUSIONS

Despite consistency in the method of capture of PROs or FPS, domain capture varied considerably across reviewed studies. Irrespective of the method of capturing PROs or FPS, the quantified level of association between these two areas was moderate at best, providing evidence that FPS and PRO assessments offer unique information to assist clinicians in their decision-making.

Dosimetric predictors of dysphonia after intensity-modulated radiotherapy for oropharyngeal carcinoma

AIMS

To investigate dosimetric predictors of voice changes after whole-field intensity-modulated radiotherapy (IMRT).

MATERIALS AND METHODS

Patients treated with whole-field IMRT for oropharyngeal/unknown primary tumours were selected for the present retrospective study having grossly uninvolved larynx at the time of radiotherapy and at least one follow-up visit. Voice changes were prospectively scored at each follow-up examination according to the Common Terminology Criteria for Adverse Events (CTCAE) v3.0 scale and self-reported by two items (HN4 and HN10) of the Functional Assessment of Cancer Therapy-Head and Neck Scale (FACT-HN) questionnaire. Predictors of toxicity were investigated at logistic regression, including various patient and tumour characteristics, as well as individual dosimetric data.

RESULTS

With a median follow-up of 18 months (range 3-46 months), peak CTCAE dysphonia was graded as 2 in 13 patients (10.5%), whereas 45 patients (36.3%) reported peak grade 0-1 voice changes according to FACT-HN4. Communication (FACT-HN10) was barely affected. At multivariate analysis, the mean laryngeal dose was an independent predictor of both grade 2 CTCAE dysphonia (odds ratio = 1.10, 95% confidence interval 1.01-1.20, P = 0.025) and grade 0-1 FACT-HN4 voice changes (odds ratio = 1.11, 95% confidence interval 1.04-1.18, P = 0.001). Further stratification optimised by a receiver operating characteristic (ROC) analysis showed that, to minimise the risk of grade 0-1 FACT-HN4 voice changes, the mean dose to the larynx has to be kept ≤ 49.4 Gy.

CONCLUSION

Voice changes after whole-field IMRT are common, but mild, and are strictly correlated to the dose received by the uninvolved larynx; in order to minimise the risk of side-effects, the mean dose to the larynx should be kept ≤ 50 Gy.

Voice reconstruction using the free ileocolon flap versus the pneumatic artificial larynx: a comparison of patients' preference and experience following laryngectomy

This study compares the psychological adjustment and voice function of patients undergoing voice rehabilitation using the free ileocolon flap for creation of a voice tube shunt and patients undergoing voice rehabilitation using the pneumatic artificial larynx. Twelve laryngectomy patients were included; six underwent free ileocolon transfer following a period of pneumatic artificial larynx use. Mean duration after laryngectomy was 5.2 years. Mean follow-up was 210 days. A chart review, questionnaires and a prospective evaluation were performed. Voice tube shunt patients had better speech function and higher self-esteem. People's discrimination and appearance when speaking were important in the patients' choice of method for rehabilitation. There was a high preference for choosing the voice tube shunt and a higher motivation and willingness to use that voice mechanism in the voice tube shunt group. Patients who undergo free flap reconstruction of voice have better speech function and self-esteem than patients who continue to use the external pneumatic device. Psychological assessments are important for surgical patients in order to evaluate a critical aspect of our perceived success - the patients' perception.

A screening questionnaire for voice problems after treatment of early glottic cancer

PURPOSE

After treatment for early glottic cancer, a considerable number of patients end up with voice problems interfering with daily life activities. A 5-item screening questionnaire was designed for detection of voice impairment. The purpose of this study is to assess psychometric properties of this questionnaire in clinical practice.

METHODS AND MATERIALS

The questionnaire was completed by 110 controls without voice complaints and 177 patients after radiotherapy or laser surgery for early glottic cancer.

RESULTS

Based on normative data of the controls, a score of 5 or less on at least 1 of the 5 questions was considered to state overall voice impairment. Reliability of the questionnaire proved to be good. Voice impairment was reported in 44% of the patients treated with radiotherapy vs. 29% of the patients treated with endoscopic laser surgery.

CONCLUSIONS

The questionnaire proved to be a reliable, valid, and feasible method to detect voice impairment in daily life. The questionnaire is easy to fill in, and interpretation is straightforward. It is useful for both radiation oncologists and otorhinolaryngologists in their follow-up of patients treated for early glottic cancer.

Studies in the quality of life of head and neck cancer patients: results of a two-year longitudinal study and a comparative cross-sectional cross-cultural survey

OBJECTIVES

To examine quality-of-life (QL) changes that occur over time among patients treated for head and neck cancer and to compare QL outcomes in two geographically separate and culturally distinct populations.

STUDY DESIGN

A prospective, observational longitudinal study was made of QL changes over time in head and neck cancer patients, and a matched-pairs cross-sectional study was conducted for comparison of QL outcomes between groups of head and neck cancer patients from two different sociocultural environments.

METHODS

Patients attending a tertiary head and neck cancer center in Auckland, New Zealand, were interviewed using a validated questionnaire before treatment and at 3, 12, and 24 months after treatment. Changes over time were assessed according to gender, site and stage of primary tumor, and type of treatment received. A second group of patients from Toronto, Ontario, Canada, were matched to the first group for age, gender, site and stage of tumor, and time since treatment and interviewed using the same questionnaire. The group comparison was followed by a matched-pairs analysis for the 12-month follow-up interval.

RESULTS

In the longitudinal study, combined modality treatment resulted in greater physical and somatic dysfunction than single modality treatment. Patients learned to cope well with dysfunction and disability and with adjusting their lifestyle so that overall QL was not related to treatment received. Even so, pain scores and measures of psychological distress were related to overall QL. Otherwise there was no consistent correlation between specific symptoms and QL. An illustration of patients' adaptation to dysfunction was evident in scores for perceived difficulty swallowing, which decrease despite the ongoing need for a soft or liquid diet. In the comparative study, significantly different global QL scores were evident in the two clinical groups studied, despite similar social, somatic, and physical functioning. There was also a significant but inconstant difference in emotional functioning. Although the clinical groups received significantly different treatment regimens, the observed differences in global QL were independent of treatment received.

CONCLUSIONS

Patients with head and neck cancer generally managed well despite disability and dysfunction after treatment. Patients' expectations, emotional responses, and desired outcomes seemed to be determined by sociocultural factors, causing different patient groups to view their overall QL outcome somewhat differently.

Voice, speech, and swallowing outcomes in laser-treated laryngeal cancer

OBJECTIVE

To describe preliminary voice, speech, and swallowing outcomes in patients treated by endoscopic laser excision of laryngeal cancer with or without adjuvant radiation therapy.

STUDY DESIGN

Retrospective review.

METHODS

Seventeen surgically treated patients (five T2 glottic and 12 clinically staged T2 supraglottic squamous cell carcinomas) participated in the study. Self-ratings of voice (Voice Handicap Index) and swallowing (M. D. Anderson Dysphagia Inventory) were completed, as well as independent auditory-perceptual ratings of voice and speech recordings.

RESULTS

Although no significant difference between Voice Handicap Index, M. D. Anderson Dysphagia Inventory, and listener ratings was identified based on tumor site and irradiation status, there was a trend toward poorer outcomes in patients who received adjuvant radiation therapy. Whereas the patients having supraglottic cancer tended to report better voice but poorer swallowing outcomes, the glottic cancer group displayed the opposite pattern. Severity on Voice Handicap Index correlated significantly with listener severity ratings of speech, suggesting that the patients' perception of their voice handicap was similar to the listeners' judgments of their speech severity.

CONCLUSIONS

The results suggest the following trends: 1) Adjuvant radiation therapy was associated with poorer outcomes for voice, speech, and swallowing and may be associated with more impairment than surgery alone and 2) poorer outcomes on voice and swallowing were observed for the glottic and supraglottic cancer groups, respectively. To bolster these preliminary findings, additional outcomes studies in patients treated with conservation therapy are needed.

Importance-rating using the University of Washington quality of life questionnaire in patients treated by primary surgery for oral and oro-pharyngeal cancer

BACKGROUND

There are now several validated and widely accepted head and neck cancer questionnaires. These record patients subjective levels of function and dysfunction, as well as symptoms related to their cancer and its treatment. One popular measure is the University of Washington head and neck cancer questionnaire (UW-QOL). Domain importance-ratings were added to the second version of the questionnaire, which was published in 1997. It is unique amongst head and neck cancer questionnaires in this respect.

AIM

The purpose of the study was to evaluate UW-QOL with particular reference to domain importance-rating. It was also the intention to investigate how the importance-ratings related to 'quality of life' and comment on the cumulative scoring of the questionnaire.

METHODS

Forty-eight patients with previously untreated oral or oro-pharyngeal cancer were recruited. All were treated by primary surgery. Questionnaires were completed pre-operatively, 6 months and 1 year post-operatively.

RESULTS

This study demonstrates a wide variation in importance-ratings. Both pre- and post-treatment there was a general lack of correlation between importance-rating and domain scores. At all time points, patients tended to rate speech, chewing and swallowing as more important than the other UW-QOL domains. The cumulative UW-QOL score correlated strongly with the new single item QOL question.

CONCLUSION

It remains unclear how best to incorporate importance-ratings into a single UW-QOL total score. However, for individual patients they can assist in setting priorities in treatment strategies.

Health-related quality of life and clinical function after primary surgery for oral cancer

Clinical function and health-related quality of life (HRQoL) are both important outcome parameters following surgery for oral and oropharyngeal cancer. The aim of this project was to explore the relationship between an 11-point clinical examination and HRQoL. Of 132 consecutive patients undergoing surgery for previously untreated disease between January 1995 and June 1997, 130 were recruited into the study. The University of Washington Quality of Life Questionnaire (UW-QoL) was completed by each patient on the day before operation and 6 and 12 months later. On each occasion the first author made an 11-point clinical examination. The main predictors of cumulative UW-QoL scores were tumour size, clinical functional score and type of operation. The trend was for a fall from preoperative levels at 6 months and then for a slight improvement at 1 year. The differential in respect of baseline function was present at all three time points in each patient group. This suggests that functional deficits at presentation persist following treatment.

Quality of life after treatment for advanced laryngeal and hypopharyngeal cancer

OBJECTIVES

To compare health-related quality of life measures after treatment for advanced (stages III and IV) laryngeal and hypopharyngeal cancers.

STUDY DESIGN

Retrospective chart review and patient response to Health Status Questionnaire-12 (HSQ-12).

METHODS

Our study included 54 patients identified from the Tumor Registry of the University of Louisville Brown Cancer Center who were diagnosed and treated between 1995 and 2000. Demographics, tumor data, and treatment information were obtained from the Tumor Registry database. Questionnaires were mailed to all patients and included telephone follow-up. Comparative data and responses were analyzed for the 24 patients who responded to the survey.

RESULTS

Fifteen patients were treated with chemotherapy and radiation therapy (CRT). Six patients underwent surgery with postoperative radiation therapy (SRT). The remaining three patients were treated with radiation therapy but were not used in this analysis. The average follow-up was 35 months after treatment. The CRT and SRT groups were statistically similar regarding age, sex, duration of follow-up, tumor grade, and tumor stage. Laryngeal primary tumors were more common in the SRT group than in the CRT group (P =.005). Eight domains were assessed by the HSQ-12: physical functioning, role-physical, bodily pain, health perception, energy/fatigue, social functioning, role-mental, and mental health. No statistical differences were found between the CRT and SRT groups, except for role limitations attributable to physical health (P =.007).

CONCLUSIONS

These results indicate that only one of eight domains differs significantly between treatment groups when using the HSQ-12. Two-year survival end-point analysis of global health assessment may represent a simplified and meaningful way to compare treatment modalities in patients with advanced-stage head and neck cancer.

Distinct patient groups in oral cancer: a prospective study of perceived health status following primary surgery

Health-related quality of life (HRQOL) is an important consideration in the management of patients with cancer. Pre-treatment data can give an indication of the anticipated response following cancer treatment. However, in order to use HRQOL data meaningfully it is essential to have an appreciation of how different patient groups respond. The aim of the study was to identify distinct patient groups at baseline using the University of Washington head and neck cancer questionnaire (UW-QOL). It was also the intention to see how these groups differed in their: (1) clinical and demographic attributes; (2) European Organisation for Research and Treatment of Cancer (EORTC) C30 and SF 36 scores; and (3) longitudinal trends over 6 and 12 months. One-hundred and thirty consecutive patients with previously untreated oral and oro-pharyngeal cancer were recruited. All were treated by primary surgery. Attrition was evident in the study but care was taken to allow for this. There were two distinct groups of patients identified by the cumulative UW-QOL score at presentation. These groups discriminated throughout the EORTC C30 and SF 36, at baseline and longitudinally, with the exception of mental health. This study demonstrates that HRQOL items are interrelated. There are difficulties in using baseline scores for treatment selection, and scores need to be interpreted in the light of clinical and demographic factors.

Evaluation of quality of life in patients definitively treated for squamous carcinoma of the head and neck

This paper reviews quality-of-life (QOL) assessment in head and neck cancer with a focus on research and methodologic developments of the past year. Issues of QOL measurement, as well as the challenges to data synthesis in light of the heterogeneity of head and neck cancer and its treatment, are discussed briefly. Methodologic advances include increased use of validated measures, longitudinal study design, and attention to patients' attitudes. Although the majority of studies assessed multiple QOL domains, including both physical/functional and emotional/social, more focused areas of investigation included pain, organ preservation, and depression. Examinations of the relation among domains suggested that impaired function does not necessarily lead to poor QOL and that the best predictor of 12-month global QOL is pretreatment global QOL. Future challenges include the need for large multi-institutional studies, consensus about instrument selection, addressing the problem of missing data, and how to apply group OOL to individual patient decisions.
