Effect of comorbidity on quality of life and treatment selection in patients with squamous cell carcinoma of the head and neck

OBJECTIVES: Comorbidity is significantly associated with diminished survival and quality of life (QOL) after treatment of head and neck squamous cell carcinoma (HNSCC). We sought to determine whether comorbidity influenced pretreatment QOL scores and treatment selection in patients with HNSCC. METHODS: The medical records of all patients diagnosed with HNSCC who participated in pretreatment QOL analysis over a 15-month period were retrospectively reviewed. Patients with a history of prior treatment for head and neck cancer, unresectable, or distant metastatic disease were excluded. The University of Washington (UW) QOL questionnaire, Performance Status Scale (PSS), and Karnofsky score were used to measure pretreatment QOL. Comorbidity was graded using the Modified Medical Comorbidity Index. RESULTS: Of 75 patients who met study criteria, 33 underwent primary surgical therapy, and 42 underwent nonoperative (radiation or chemoradiation) therapy. Treatment groups did not differ with respect to patient demographics, UW QOL scores, PSS scores, Karnofsky score, or comorbidity. Treatment groups differed significantly by disease stage and primary site. Patients with advanced stage disease (III/IV) or oropharyngeal primary tumors were more likely to undergo nonoperative treatment, compared with patients with early stage disease (I/II) or oral cavity primary tumors (P < .005). No significant association was found between comorbidity and pretreatment QOL scores. CONCLUSIONS: Comorbidity was not significantly associated with treatment selection or pretreatment QOL scores in patients with HNSCC. Location of the primary tumor and disease stage were significantly associated with treatment selection. Further studies are required to determine the effect of comorbidity on patient and tumor responses to treatment.     

Gastrostomy tubes in patients with advanced head and neck cancer

OBJECTIVES: To measure the percentage of patients requiring gastrostomy tubes (G-tubes) and the timing of their placement, in addition to studying whether pretreatment variables (T stage, tumor site, N stage) and intratreatment variables (weight loss during treatment) are valid predictors for the need for G-tube placement. STUDY DESIGN: Retrospective case control study. METHODS: Retrospective review of a prospectively collected database with chart reviews was carried out on 477 patients treated on a regimen of intraarterial cisplatin and concurrent radiation. The likelihood of requiring a G-tube was calculated by studying several independent variables using chi-square analysis and the unpaired t test. RESULTS: Two hundred twenty (46%) patients had G-tubes placed, with mean time of placement being on day 20 after the initiation of treatment. Patients with T4 disease were statistically more likely to require a G-tube (50% vs. 37%, P < .05). Patients were less likely to require a G-tube when the primary site of tumor involved the larynx or paranasal sinuses (P < .05). There were no statistically significant differences between the two groups with regards to patient age, sex, N stage, and weight changes over the course of treatment. The odds of requiring a G-tube were highest for tumors involving the hypopharynx (80%), oral cavity (52%), and oropharynx (49%). CONCLUSIONS: Although clinical judgment appears to be sufficient for deciding when G-tube placement is warranted in our population, the threshold for placing a tube should be lower in those patients who had a higher likelihood of requiring a G-tube during the course of treatment, including those with advanced disease of the oral cavity, oropharynx, and hypopharynx.     

Trismus in patients with head and neck cancer and 5-year overall survival

Abstract

Background: Trismus is a common complication of radiotherapy for head and neck cancer but its impact on survival is unknown.

Aims/Objectives: This prospective study evaluates the incidence of trismus in patients with head and neck cancer receiving radiotherapy and the impact of trismus on 5-year overall survival.

Material and methods: Two hundred forty-four patients with head and neck cancer were included. All patients received instructions on jaw exercises and were evaluated before initiation of radiotherapy and at 2, 6, and 12 months after termination of radiotherapy.

Results: One year after treatment 25% had a reduced maximum interincisal opening (MIO) of 13?mm or more as compared to the pretreatment MIO. Trismus was most prevalent in patients with oral and oropharyngeal cancer. A trend towards worse 5-year overall survival was seen among patients with trismus.

Conclusions: The trismus rate was approximately 30% at 12 months. Jaw exercises should primarily be offered to patients with oral and oropharyngeal cancer who are most likely to benefit. Further studies are required to investigate the effect of trismus on survival.

Significance: This study identifies patients likely to benefit from jaw exercises and provides basis for further research on trismus and survival.     

Racial disparities in patients with head and neck squamous cell carcinoma

OBJECTIVES/HYPOTHESIS: Black patients are reported to have a higher incidence of advanced disease and increased mortality from head and neck squamous cell carcinoma (HNSCC) but constitute the minority of patients in large-scale studies investigating the effect of race on outcome. This study sought to determine if racial disparities exist between black and white patients with HNSCC treated at a single large institution in the South with a high proportion of black patients. STUDY DESIGN: The authors conducted a nonrandomized retrospective cohort analysis. METHODS: The tumor registry was used to identify patients diagnosed with HNSCC from 1985 to 2002. The medical records of non-Hispanic white and black adult patients were retrospectively reviewed. Median household income, percentage of population below poverty level, and education level based on census tract and block information were obtained from U.S. Census 2000 data. Standard statistical analysis, including Kaplan-Meier survival curve analysis and Cox proportional hazards models, was used to analyze the effects of covariables on survival. RESULTS: A total of 1,128 patients met study criteria (478 black, 650 white). Compared with white patients, black patients were significantly younger (mean age, 53.9 vs. 56.4 years, P<.0001), male (81.2% vs. 72.3%, P=.0005), more commonly abused alcohol (88.0% vs. 74.3%, P<.0001), and were significantly less likely to have insurance (8.6% vs. 21.7%, P<.0001). There was no difference in the incidence of tobacco use (91.7%), advanced comorbidity (35.9%), or primary tumor site. Black patients had a significantly greater incidence of stage IV disease (65.7% vs. 46.6%, P<.0001) and nonoperative treatment (48.7% vs. 30.8%, P<.0001), which was performed for inoperable disease in 57.1% of black compared with 31.0% of white patients (P<.0001). Black patients resided in census block groups with significantly lower mean education level, median income, and a higher percentage of population below poverty compared with white patients. The 5-year disease-specific survival differed significantly between black (29.3%) and white (54.7%) patients (P<.0001). Cox proportional hazards models revealed that alcohol abuse, advanced TNM stage, high tumor grade, nodal disease, extracapsular spread, advanced comorbidity, and regional or distant metastatic disease were associated with poorer survival for all patients. An interaction with race was found for insurance status, nonoperative treatment, and extracapsular spread. Stepwise variable selection adjusting for patient, tumor, and treatment characteristics showed a significant effect only for race by payor status on disease-specific survival (P=.0228). CONCLUSIONS: Insurance status, treatment, and extracapsular spread differentially affected the survival of black patients compared with white patients. Only insurance status had a significant effect on survival in black patients after controlling for other variables. These data suggest that racial differences in HNSCC outcomes are primarily related to differences in access to health care.     

Survival of adult patients with head and neck soft tissue sarcomas

A retrospective review and survival analysis is presented of 58 adult patients referred between 1963 and 1993 for treatment of a head and neck soft tissue sarcoma. The 5 year overall and disease-free survival was 60% and 52% respectively. Univariate analysis indicated that age, positive margins. bone invasion, distant metastases, single modality treatment, histological grading, sites below the deep fascia and size might be predictors of survival. On multivariate analysis, age, histological grade, distant metastases, site and referral for recurrent disease emerged as prognostic factors known before treatment. By including variables known after treatment, age remained the most important independent prognostic factor followed by the presence of free margins, histological grading and distant metastases at presentation.     

Multiple primary malignant tumours in patients with head and neck cancer: the implications for follow-up

The pattern of second primary cancer occurrence in 518 Scottish patients with head and neck cancer was determined by a retrospective study. The overall incidence of second cancers was 9% but the true incidence increased steadily in the years following initial diagnosis to reach a maximum of 21% at 11 years. After 4 years of follow-up patients were more likely to die from a second primary cancer than from the effects of the initial tumour. The Scottish cohort differed from previously reported, overseas, study groups in having a high incidence of second primary cancers in sites outside the upper aerodigestive tract. This potential demographic difference suggests a need for local audit prior to design and implementation of screening protocols for second primary cancers.     

Demands on caring relatives of head and neck cancer patients

BACKGROUND: Relatives of cancer patients experience high levels of stress that influence the quality of life of these individuals. To investigate whether there is a necessity for simultaneous supportive care of patient relatives, we performed for the first time a study asking the closest relatives of head and neck cancer patients about their needs during and after the treatment to consider how to optimize the situation for such patient groups. MATERIAL AND METHODS: Patients' relatives were assessed using an anonymous self-report questionnaire that was established in our department by expanding on a questionnaire for cancer patients' relatives from the psycho-oncologic society in Switzerland. The evaluation was multidimensional, cancer specific, and relative based. RESULTS: Relatives feel confronted themselves with cancer, although indirectly. The majority of the respondents were of the opinion that simultaneous psychological care of the patients and for the caring relatives would be helpful to cope with the situation. CONCLUSION: This study shows the significant impact of cancer on caring relatives of head and neck cancer patients. In our opinion, health services should become more aware of this potential to ensure that the needs of the involved patient relatives are met as well as those of the patients.     

Palliative care in patients with cancer of the head and neck

Palliative care is the active total care of patients whose disease is not responsive to curative treatment. Patients with end-stage head and neck cancer have particular problems because of the impact of the tumour on the airway, the upper gastrointestinal tract and the major senses. Patients referred for palliative care were identified from the hospice database and the nature, incidence and management of their problems, and the role of the hospice in their care, was reviewed from in-patient and home care notes and patient-generated problem lists. Thirty-two male and six female patients with a median age of 64 years were identified. Locoregional recurrence was present in 79% of patients. Pain, weight loss, feeding difficulties, dysphagia, respiratory symptoms, xerostomia, oral thrush and communication difficulties were the major problems. The management of each, and of the terminal events encountered in the group, is discussed.     

Life-satisfaction in patients with head and neck cancer

Life-satisfaction is a measure of a patient's perception of the difference between his reality and his needs, or wants. This study reports the results of a longitudinal survey of patients’self-reported life-satisfaction following treatment for head and neck cancer. Life-satisfaction scores improved with time, and were related to pain, speech difficulty, and dysphagia. Lack of adequate family support was also important, although an uncommon problem. Treatment modality did not emerge as a significant determinant of life-satisfaction; speech difficulties were more likely to be due to articulation problems than voicing difficulty.     

Chest computerized tomography scanning in patients presenting with head and neck cancer

Between 1 to 16% of patients with head and neck squamous cell carcinoma (HNSCC) have synchronous tumours; the majority (>50%) occurring within the lung. Previous studies have relied upon endoscopy and chest radiographs. The aim of this study was to determine the incidence of synchronous intrapulmonary tumours in this group of patients using computerized tomography (CT) scanning. Over 36 months, 111 consecutive patients were assessed at presentation by contrast enhanced CT scanning from the skull base to the diaphragm. Chest scans showed intrapulmonary lesions in 17 patients and 10 have, with time, been confirmed as neoplastic. These allowed treatment of three primary bronchial carcinomas following radical treatment of the index tumour and cancellation of radical treatment in five patients with metastases. Two patients with possible metastases at presentation underwent radical treatment to the index tumour with subsequent follow-up confirming metastatic chest disease. All 10 patients eventually died of either locoregional or metastatic disease. This is one of the first prospective reports of chest scanning in patients with head and neck cancer. An additional chest scan in this group, many of whom undergo a staging scan of the neck, requires an extra 10 min with no further contrast and in this study yielded a synchronous tumour rate of 9%.     

Long-term quality of life of patients with head and neck cancer

Objectives: To describe prospectively the long‐term changes of quality of life and mood in patients with squamous cell carcinoma of the head and neck treated with surgery and/or radiotherapy. Patients and Methods: One hundred seven patients completed the European Organization for Research and Treatment of Cancer (EORTC) Core Questionnaire, the EORTC Head and Neck Cancer Module, and the Center for Epidemiological Studies Depression Scale before treatment, and 6, 12, 24, and 36 months later. Results: There was limited deterioration of physical and role functioning and of many head and neck symptoms at 6 months, with improvement thereafter. After 36 months only physical functioning, taste/smell, dry mouth, and sticky saliva were significantly worse, compared with baseline. Female sex, higher cancer stage, and combination treatment were associated with more symptoms and worse functioning. Despite physical deterioration, there was a gradual improvement of depressive symptomatology and global quality of life. Conclusion: Treatment for head and neck cancer results in short‐term morbidity, most of which resolves within 1 year. Despite an initially high level of depressive symptomatology, there is gradual improvement of psychological functioning and global quality of life over the course of 3 years. In this prospective study, the impact of the disease and its treatment in long‐term survivors seems to be less severe than it is often assumed to be.
