The performance status scale for head and neck cancer patients and the functional assessment of cancer therapy-head and neck scale: A study of utility and validity

The goal of this investigation was to examine the relationship between, and application of, two disease specific quality of life (QL) measures currently being employed for head and neck cancer patients: the Functional Assessment of Cancer Therapy‐Head and Neck Scale (FACT‐H & N) and the Performance Status Scale for Head and Neck Cancer Patients (PSS‐HN).

A performance status scale for head and neck cancer patients

Effective assessment of treatment outcome and the development of successful rehabilitation for head and neck cancer patients demand an evaluation of the relevant parameters of functional status. This paper reports the development and testing of a new Performance Status Scale for Head and Neck Cancer Patients designed to assess the unique areas of dysfunction experienced by this population. The instrument is a simple, practical, clinician‐rated assessment tool consisting of three subscales: (1) Understandability of Speech, (2) Normalcy of Diet, and (3) Eating in Public. The scale was administered to a group of 181 head and neck patients and a comparison group of 30 breast cancer patients. Results indicate that the scale is reliable across raters and sensitive to functional differences across a broad spectrum of head and neck cancer.

Single-Agent Versus Combination Chemotherapy in Advanced Non-Small-Cell Lung Cancer: The Cancer and Leukemia Group B (study 9730)

PURPOSE We compared the efficacy of combination chemotherapy versus single-agent therapy in patients with advanced non-small-cell lung cancer. PATIENTS AND METHODS A total of 561 eligible patients were randomly assigned to receive paclitaxel alone or in combination with carboplatin. RESULTS The response rate was 17% in the paclitaxel arm and 30% in the carboplatin-paclitaxel arm (P < .0001). Median failure-free survival was 2.5 months in the paclitaxel arm and 4.6 months in the carboplatin-paclitaxel arm (P = .0002). Median survival times were 6.7 months (95% CI, 5.8 to 7.8) and 8.8 months (95% CI, 8.0 to 9.9), and 1-year survival rates were 32% (95% CI, 27% to 38%), and 37% (95% CI, 32% to 43%), respectively. The overall survival distributions were not statistically different: hazard ratio = 0.91 (95% CI, 0.77 to 1.17; P = .25). Hematological toxicity and nausea were more frequent in the combination arm, but febrile neutropenia and toxic deaths were equally low in both arms. There was no significant survival difference in elderly patients. Performance status 2 patients treated with combination chemotherapy had a better survival rate than those treated with single-agent therapy (P = .019). CONCLUSION Combination chemotherapy improves response rate and failure-free survival compared with single-agent therapy, but there was no statistically significant difference in the primary end point of overall survival. The results in elderly patients were similar to younger patients. Performance status 2 patients had a superior outcome when treated with combination chemotherapy.

American Society of Clinical Oncology Clinical Practice Guideline for the Use of Larynx-Preservation Strategies in the Treatment of Laryngeal Cancer

PURPOSE To develop a clinical practice guideline for treatment of laryngeal cancer with the intent of preserving the larynx (either the organ itself or its function). This guideline is intended for use by oncologists in the care of patients outside of clinical trials. METHODS A multidisciplinary Expert Panel determined the clinical management questions to be addressed and reviewed the literature available through November 2005, with emphasis given to randomized controlled trials of site-specific disease. Survival, rate of larynx preservation, and toxicities were the principal outcomes assessed. The guideline underwent internal review and approval by the Panel, as well as external review by additional experts, members of the American Society of Clinical Oncology (ASCO) Health Services Committee, and the ASCO Board of Directors. RESULTS Evidence supports the use of larynx-preservation approaches for appropriately selected patients without a compromise in survival; however, no larynx-preservation approach offers a survival advantage compared with total laryngectomy and adjuvant therapy with rehabilitation as indicated. RECOMMENDATIONS All patients with T1 or T2 laryngeal cancer, with rare exception, should be treated initially with intent to preserve the larynx. For most patients with T3 or T4 disease without tumor invasion through cartilage into soft tissues, a larynx-preservation approach is an appropriate, standard treatment option, and concurrent chemoradiotherapy therapy is the most widely applicable approach. To ensure an optimum outcome, special expertise and a multidisciplinary team are necessary, and the team should fully discuss with the patient the advantages and disadvantages of larynx-preservation options compared with treatments that include total laryngectomy.

Weekly Carboplatin and Paclitaxel Followed by Concomitant Paclitaxel, Fluorouracil, and Hydroxyurea Chemoradiotherapy: Curative and Organ-Preserving Therapy for Advanced Head and Neck Cancer

PURPOSE The paclitaxel, fluorouracil, and hydroxyurea regimen of paclitaxel, infusional fluorouracil, hydroxyurea, and twice-daily radiation therapy (TFHX) administered every other week has resulted in 3-year survival rates of 60% of stage IV patients. Locoregional and distant failure rates were 13% and 23%, respectively. To reduce distant failure rates, we added a brief course of induction chemotherapy to TFHX. PATIENTS AND METHODS Sixty-nine patients received six weekly doses of carboplatin (AUC2) and paclitaxel (135 mg/m2) followed by five cycles of TFHX. RESULTS Ninety-six percent had stage IV disease. Response to induction chemotherapy was partial response 52% and complete response (CR) 35%. Symptomatically, there was a significant reduction in mouth and throat pain. The most common grade 3 or 4 toxicity was neutropenia (36%). Best response following completion of TFHX was CR in 83%. Toxicities of TFHX consisted of grade 3 or 4 mucositis (74% and 2%) and dermatitis (47% and 14%). At a median follow-up of 28 months, locoregional or systemic disease progression were each noted in five patients. The overall 3-year progression-free survival was 80% (95% confidence interval [CI], 71% to 90%), and the 2- and 3-year overall survival rates were 77% (95% CI, 66% to 87%) and 70% (95% CI, 59% to 82%), respectively. At 12 months, five patients were completely feeding-tube dependent. CONCLUSION Administration of carboplatin and paclitaxel before TFHX chemoradiotherapy results in high response activity and may decrease distant failure rates. Overall survival, progression, and organ preservation/functional outcome data support definitive evaluation of this approach.

Quality of Life and Performance in Advanced Head and Neck Cancer Patients on Concomitant Chemoradiotherapy: A Prospective Examination

PURPOSE To prospectively evaluate performance and quality of life (QOL) in advanced-stage head and neck cancer (HNC) patients on a curative-intent, concomitant-chemoradiotherapy (CT/XRT) (twice-daily radiation, fluorouracil, hydroxyurea, and cisplatin) regimen aimed at improving locoregional control, survival, and QOL. PATIENTS AND METHODS Sixty-four patients were assessed before, during, and at 3-month intervals after treatment. Standardized measures of QOL (Functional Assessment of Cancer Therapy-Head and Neck), performance (Performance Status Scale for Head and Neck Cancer Patients and Karnofsky Performance Status Rating Scale), and patient-reported symptoms (McMaster University Head and Neck Radiotherapy Questionnaire) were administered. RESULTS Acute treatment toxicities were severe, with declines in virtually all QOL and functional domains. Marked improvement was seen by 12 months; general functional and physical measures returned to baseline levels of good to excellent. Although up to a third of the patients continued to report problems with swallowing, hoarseness, and mouth pain, these difficulties were present in similar magnitudes before treatment. The following symptoms were more frequent at 12 months: dry mouth (58% v 17%), difficulties tasting (32% v 8%), and soft food diet (82% v 42%). Twelve-month diet was not related to pretreatment functioning, disease, treatment, or patient characteristics. Twelve-month QOL was best predicted by pretreatment QOL, with very little relationship to residual side effects or functional impairments. Small numbers of patients in four of the five disease sites precluded examination of outcome by site. CONCLUSION These data support the feasibility of intense CT/XRT as primary treatment for advanced HNC. Results confirm acute toxicity but indicate that many of the treatment-related performance and QOL declines resolve by 12 months. The persistent inability to eat a full range of foods warrants further attention and monitoring.

Phase II Trial of Gefitinib 250 mg Daily in Patients with Recurrent and/or Metastatic Squamous Cell Carcinoma of the Head and Neck

Purpose: An objective response rate of 11% was reported in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN) treated with 500 mg daily gefitinib although the recommended dose in lung cancer is 250 mg. This study evaluated the efficacy and toxicity of 250 mg daily gefitinib in patients with recurrent and/or metastatic SCCHN. Experimental Design: Phase II trial with objective response rate as the primary end point. Measurements of quality of life and levels of serum vascular endothelial growth factor and transforming growth factor-α were assessed before and during therapy. Results: In 70 patients, 1 (1.4%) partial response was observed. Median progression-free survival and overall survival were 1.8 and 5.5 months, respectively. Quality of life scores improved transiently during the first weeks of therapy before returning to baseline. Median vascular endothelial growth factor and transforming growth factor-α levels were above the normal range but were not predictive of outcome. Four patients experienced grade 3 drug-related adverse events. Rash of any grade was observed in 64% of subjects. Correlation between disease control (partial response + stable disease), progression-free survival, and overall survival and grade of cutaneous toxicity was observed (P = 0.001, 0.001, and 0.008 respectively). Conclusions: Gefitinib monotherapy at 250 mg in recurrent and/or metastatic SCCHN seems to have less activity than was previously observed for 500 mg daily. A dose-response relationship may exist for this agent in SCCHN and grade of cutaneous toxicity attributable to gefitinib is a clinical predictor of better outcome.

Concomitant Chemoradiotherapy as Primary Therapy for Locoregionally Advanced Head and Neck Cancer

PURPOSE To achieve locoregional control of head and neck cancer, survival, and organ preservation using intensive concomitant chemoradiotherapy. PATIENTS AND METHODS This study was a phase II trial of chemoradiotherapy with cisplatin 100 mg/m(2) every 28 days, infusional fluorouracil 800 mg/m(2)/d for 5 days, hydroxyurea 1 g orally every 12 hours for 11 doses, and radiotherapy twice daily at 1.5 Gy/fraction on days 1 through 5 (total dose, 15 Gy). Five days of treatment were followed by 9 days of rest, during which time patients received granulocyte colony-stimulating factor. Five cycles (three with cisplatin) were administered over 10 weeks (total radiotherapy dose, </= 75 Gy). Adjuvant chemoprevention with retinoic acid and interferon alfa-2A was offered. RESULTS Seventy-six patients were treated (stage IV, 93%; N2, 54%; N3, 21%). At a median follow-up of 38 months, the 3-year progression-free survival is 72%, locoregional control 92%, systemic control 83%, and overall survival 55%. Toxicities included mucositis (grade 3, 45%; grade 4, 12%), neutropenia (grade 4, 39%), and thrombocytopenia (grade 4, 53%). Surgery at the primary site was performed in 13 patients, and 39 had neck dissection. A majority of patients declined adjuvant chemoprevention. Pharmacokinetic parameters were not prognostic of tumor control. Quality of life declined during treatment but returned from good to excellent by 12 months after treatment. CONCLUSION Intensive concomitant chemoradiotherapy leads to high locoregional control and survival rates with organ preservation and a reversal of the historical pattern of failure (distant > locoregional). Surgery after concomitant chemoradiotherapy is feasible. Compliance with adjuvant chemoprevention is poor. Identification of less toxic regimens and improved distant disease control emerge as important future research goals.

Concomitant Infusional Paclitaxel and Fluorouracil, Oral Hydroxyurea, and Hyperfractionated Radiation for Locally Advanced Squamous Head and Neck Cancer

PURPOSE To improve local disease control and survival with organ preservation, we conducted a phase II multi-institutional trial with a concomitant taxane-based chemotherapy and hyperfractionated radiation regimen. PATIENTS AND METHODS Sixty-four patients with locally advanced squamous cancers (stage IV, 98%; N2/3, 81%) were treated on an intensive regimen consisting of 5-day (120-hour) infusions of paclitaxel (20 mg/m(2)/d) and fluorouracil (600 mg/m(2)/d), oral hydroxyurea 500 mg every 12 hours for 11 doses, and radiation 1.5 Gy bid (T-FH2X). Chemoradiation was administered concomitantly on days 1 to 5 of each 14-day cycle. A full treatment course consisted of five cycles during a 10-week period to a total radiation dose of 72 to 75 Gy. RESULTS The median follow-up for the group is 34 months. At 3 years, progression-free survival is 63%, locoregional control is 86%, and systemic control is 79%; overall survival is 60%. Seventeen patients died of recurrent cancer, two died of second primary cancers, and four died of other causes. Side effects observed include anemia (22% required transfusion), leucopenia (34%, grade 3 to 4), and mucositis (84%, grade 3 to 4). Organ preservation principles were maintained. At 1 year posttreatment, 61% of patients had severe xerostomia and 47% had compromised swallowing. There was little disturbance of speech quality in 97% of patients at the same follow-up point. CONCLUSION T-FH2X is a highly active and tolerable concomitant chemotherapy and hyperfractionated radiation regimen that induces sustained local tumor control and holds promise for improved survival with organ preservation in high-risk patients. Identification of less toxic therapy and improved distant disease control are needed. T-FH2X should be tested in a randomized trial and compared with a less intensive concomitant regimen that uses once-daily radiation fractionation.

Longitudinal assessment of quality of life in laryngeal cancer patients

Although quality of life (QL) and performance status are important outcomes in head and neck (HN) cancer, there is little systematic inclusion of these parameters in treatment trials.
