Role of radiotherapy in adenoid cystic carcinoma of the head and neck.

This study retrospectively reviewed 183 cases of adenoid cystic carcinoma treated over 40 years. The local recurrence free survival rate was 68.2 per cent at five years and 40.8 per cent at 10 years. At 10 years, local recurrence free survival was significantly worse following radiotherapy alone (0 per cent), compared with surgery alone (41.8 per cent, p = 0.004) or combined with post-operative radiotherapy (43.5 per cent, p = 0.001). Neither tumour stage three or four, perineural invasion, solid subtype nor involved margins predicted local recurrence. Treatment with radiotherapy alone resulted in worse survival than surgery alone (p = 0.002) or combined with post-operative radiotherapy (p = 0.001). Survival rates following local recurrence (n = 34) were higher following surgery (p = 0.006) but not significantly improved following radiotherapy (p = 0.139). Chemotherapy for distant metastases did not prolong survival (p = 0.747) but did result in improved eating and aesthetics scores, while decreasing overall physical health. These results indicate that surgery is preferable for primary and recurrent adenoid cystic carcinoma of the head and neck. The incidence of local recurrence following surgery and postoperative radiotherapy was similar to surgery alone cases although the latter had less adverse prognostic features. Contemporary chemotherapy may benefit quality of life but not survival in patients with distant metastases due to adenoid cystic carcinoma of the head and neck.

National survey of head and neck verrucous carcinoma: patterns of presentation, care, and outcome.

BACKGROUND: Verrucous carcinoma is distinguished by controversy regarding appropriate diagnosis and treatment. This study provides a contemporary survey of demographics, patterns of care, and outcome for this disease in the United States. METHODS: The National Cancer Data Base had 2350 cases of verrucous carcinoma of the head and neck diagnosed between 1985 and 1996. Statistical procedures included chi-square analyses, Student t tests, and relative survival. RESULTS: Tumors originated most frequently in the oral cavity (55.9%) and larynx (35.2%). Although most patients were male (60.0%), oral cavity tumors were more common among older females. The most prevalent treatment was surgery alone (69.7%), followed by surgery combined with irradiation (11.0%) and irradiation alone (10.3%). For oral cavity tumors, surgery alone was more common among early (85.8%) than advanced cases (56.9%); a larger proportion of advanced disease received radiation alone or surgery and irradiation combined. Most laryngeal tumors were treated with surgery (60.3% for early and 55.6% for advanced disease), but a higher proportion received radiation alone or surgery combined with radiation compared with oral cavity cases. Five-year relative survival was 77.9%. For localized disease, survival after surgery was 88.9% compared with 57.6% after irradiation. CONCLUSIONS: Demographic differences implicate different mechanisms of carcinogenesis for verrucous carcinoma arising in the oral cavity and the larynx. Although selection bias may account for the differences observed, patients receiving initial treatment with surgery had better survival than those treated with irradiation, especially for cases originating in the oral cavity.

Small bowel sarcoma: analysis of survival from the National Cancer Data Base.

BACKGROUND: Small bowel sarcomas (SBS) are rare, accounting for 10% of small bowel cancers. As a result, few studies of SBS have had enough patients to accurately define their natural history and to determine the factors that have an impact on patient survival. The objective of this study was to examine patient and tumor factors in SBS and to determine prognostic factors for disease-specific survival (DSS) using the National Cancer Data Base. METHODS: Data from the National Cancer Data Base for patients diagnosed with primary SBS between 1985 and 1995 were analyzed. The chi2 statistic was used to determine significant differences between groups of patient, tumor, and treatment factors. DSS was calculated for patients diagnosed between 1985 and 1990. Significant differences in survival were determined using the Wilcoxon statistic for univariate analyses and by Cox regression in multivariate analyses. RESULTS: Of 14,253 small bowel tumors diagnosed between 1985 and 1995, sarcomas represented 10.1%. Overall, 5-year DSS was 38.9%, with a median survival of 34.1 months (n = 590). By univariate analysis, patient age, sex, tumor size, tumor grade, histologic type, general summary stage, nodal status, and whether cancer-directed surgery was performed were significantly correlated with DSS. In multivariate analysis, tumor size <5 cm, leiomyosarcoma histology, and localized disease were found to be significant favorable prognostic factors for DSS. CONCLUSIONS: SBS are rare tumors that are challenging in terms of their histopathologic classification, grading, and staging. Patients with SBS were treated predominantly by surgery, with a minority receiving adjuvant therapy. Tumor size, histologic type, and general summary stage were independent prognostic factors for 5-year DSS in patients with SBS, which is improved relative to 5-year DSS seen in patients with small bowel adenocarcinoma.

The fibula osteocutaneous flap in head and neck reconstruction: a critical evaluation of donor site morbidity.

OBJECTIVES: To (1) compare the complications and functional outcome of primary closure vs split-thickness skin grafting of the fibula osteocutaneous flap donor site, (2) identify patient-mix or treatment factors related to donor site complications, and (3) address early detection and management of donor site complications. DESIGN: Retrospective review and questionnaire study. SETTING: Two university tertiary referral centers. PATIENTS: Fifty-three patients (31 men and 22 women, ages 20 to 80 years) who underwent fibula osteocutaneous free tissue transfer between February 1992 and January 1997. MAIN OUTCOME MEASURES: Minor complications; major complications; and postoperative function, including sensory and motor deficits, pain, swelling, temperature intolerance, and activities of daily living. RESULTS: Four patients developed major wound complications (group 1), 11 patients developed minor wound complications (group 2), and 38 patients had no wound complications (group 3). The donor site was closed primarily in 26 patients and with a split-thickness skin graft in the remaining 27 patients. Major wound complications developed in 3 patients (12%) who underwent primary closure and 1 patient (4%) who underwent split-thickness skin grafting. Minor wound complications developed in 7 (27%) of the patients who underwent primary closure and 4 patients (15%) who underwent split-thickness skin grafting. Three patients who had major complications had residual sensory or motor deficits that resulted in impaired gait or alteration in their daily activities. Comparing all patients with complications (groups 1 and 2) to patients with no complications (group 3) demonstrated an increased incidence of donor site complications in heavy smokers (P<.05) and a strong trend toward higher donor site complications in patients who underwent primary closure (P =.10). Although trends were identified, no significant differences were found in age, comorbid illnesses, alcohol use, preoperative laboratory values, operating time, tourniquet time, or skin paddle width. CONCLUSIONS: A variety of patient-mix and operative factors are likely related to the development of donor site wound complications. Width of the skin paddle alone is not a reliable criterion for determining the need to skin graft the donor site. Primary closure tended to result in a higher rate of both major and minor wound complications compared with split-thickness skin grafting. Primary closure of fibula donor site defects should be undertaken if this can be accomplished with no tension along the suture line. If tension at the suture line is present, a skin graft should be strongly considered to minimize the possibility of a wound complication. Arch Otolaryngol Head Neck Surg. 2000;126:1467-1472

National cancer database report on chondrosarcoma of the head and neck.

BACKGROUND: Management of chondrosarcoma of the head and neck is largely based on single-institution reports with small numbers accrued over several decades. METHODS: The American College of Surgeons' National Cancer Data Base included 400 cases of chondrosarcoma of the head and neck diagnosed between 1985 and 1995. Chi square analyses of selected contingency tables and Wilcoxon regression analyses of selected survival stratifications were performed. RESULTS: Histologic types included conventional (80.8%), myxoid (10.5%), and mesenchymal (8.8%). The mesenchymal and myxoid subtypes were rare among white patients (17.1%) and more common among African-American (31.8%) and Hispanic patients (44.9%). Treatment was most commonly surgery alone (59.5%) and surgery with irradiation (21.0%). Disease-specific survival was 87.2% at 5 years and 70.6% at 10 years. Worse 5-year survival was associated with higher grade (67.3%), regional or distant spread (71.0%), and the myxoid (45.0%) or mesenchymal (53.2%) subtypes. CONCLUSIONS: Chondrosarcoma of the head and neck encompasses a variety of lesions that differ substantially by demographic and tumor characteristics. Individual tumors can be classified further according to site of origin, histologic subtype, and tumor grade, which can be used to predict biologic behavior and prognosis.

Laryngeal cancer cost analysis: association of case-mix and treatment characteristics with medical charges.

OBJECTIVES: To examine the relationship of various pretreatment case-mix characteristics and treatment modalities with medical charges incurred during diagnosis, treatment, and 2-year follow-up for patients with laryngeal cancer. DESIGN: Retrospective chart review and billing record analysis. METHODS: The charts and billing records of patients diagnosed with laryngeal cancer at the University of Iowa Hospitals and Clinics (UIHC) between January 1, 1991 and December 31, 1994 were reviewed. The independent variables included various pretreatment patient-mix and tumor characteristics (age, AJCC TNM clinical stage, smoking history, ASA class, and comorbidity as defined by Kaplan-Feinstein grade) as well as type of treatment. The dependent variables included total physician, office, and university hospital-based charges incurred during the pretreatment evaluation and 0- to 3-, 3- to 12, and 12- to 24-month billing periods after the initiation of cancer-directed therapy. Total 1-year and 2-year charges were also evaluated. Univariate and multivariate analyses were used to investigate the relationships between dependent and independent variables and to develop models predictive of management charges during the individual and total billing periods. RESULTS: Pretreatment charges showed no significant associations (P < .05) with any of the independent variables. Multiple regression analyses indicated that comorbidity, stage, and initial treatment modality were significant variables in one or more of the models predicting charges incurred during the 0- to 3-month, 3- to 12-month, total 1-year, and total 2-year billing periods. The models yielded R2 values for the total 1- and 2-year billing periods of 0.5246 and 0.5055, respectively. CONCLUSIONS: This work supports continued study of measures that may result in earlier detection of laryngeal cancer as a potential means of reducing management charges. These results also indicate that a more accurate method of stratifying the disease severity of laryngeal cancer patients for reimbursement purposes would include measurements of the severity of the index disease as well as comorbid diseases.

Assessing head and neck cancer patient outcome domains.

BACKGROUND: The purpose of this study was to assess the relative importance on patients' lives of multiple outcomes resulting from the management of head and neck cancer (HNC). METHODS: HNC patients filled out a disease-specific quality of life (QOL) survey covering 5 domains (speech, eating, aesthetics, pain/discomfort, and social/role functioning). Logistic regression was used to determine which of these domains best predicted the patients' response to a single, overall QOL assessment. RESULTS: In univariate analyses, all 5 domains were significantly correlated to QOL (p<.0001), with correlation coefficients ranging from.48 for eating to.64 for social/role functioning. Logistic regression indicated that speech and eating best predicted QOL (R(2) =.4647), with odds-ratios of 2. 96 for speech and 2.49 for eating. CONCLUSIONS: These data demonstrated that, for this group of patients, speech has the most impact on well-being, whereas eating has a substantial, unrelated influence. This is important information in counseling patients about treatment plans that have different levels of impairment.

The American College of Surgeons Commission on Cancer and the American Cancer Society. The National Cancer Data Base report on age, gender, treatment, and outcomes of patients with chronic lymphocytic leukemia.

BACKGROUND: The natural history of chronic lymphocytic leukemia (CLL) is changing, although the reasons (potential changes in the disease's biology or in patterns in patient characteristics, treatment, or referral) are unclear. METHODS: This report uses National Cancer Data Base (NCDB) data, which reflect a hospital-based patient population from a broad spectrum of hospitals in the United States. Age, gender, race/ethnicity, income, treatment, overall survival, and relative survival were evaluated according to time period (1985-1990 and 1991-1995). Comparisons were made with U. S. population figures for 1990 and with series published over the last 70 years. RESULTS: CLL comprised 22.6% of the 108,396 cases of leukemia in the data base. The risk of developing CLL increased progressively with age and did not plateau; the average age was 69.6 years. At the time of initial diagnosis, 60.5% of patients received no treatment (this proportion increased from 58.1% to 62.7% between the 2 time periods). Overall survival was 48.2% at 5 years and 22.5% at 10 years. The 5-year relative survival was 69.5%, 72.2%, 63.1%, and 41.7% for age groups <40, 40-59, 60-79, and 80+ years, respectively; these rates indicated that CLL, and not comorbid disease, caused the greatest percentage of deaths. CONCLUSIONS: The risk of developing CLL increases progressively with age without plateauing and is 2.8 times higher for older men than for older women. There is an increasing trend toward no treatment at the time of initial diagnosis. Long term overall survival of CLL patients is poor. CLL is a more fatal disease among older individuals because of the disease itself, not because of comorbid conditions.

The American College of Surgeons Commission on Cancer and the American Cancer Society. Adenocarcinoma of the small bowel: review of the National Cancer Data Base, 1985-1995.

BACKGROUND: Small bowel adenocarcinoma (SBA) accounts for 2% of gastrointestinal (GI) tumors and 1% of GI cancer deaths. The objective of this study was to review the National Cancer Data Base (NCDB) to identify case-mix characteristics, patterns of treatment, and factors influencing survival of patients with SBA. METHODS: NCDB data from patients diagnosed with primary SBA between 1985-1995 were analyzed. Chi-square statistics were used to compare differences between groups. Disease specific survival (DSS) was calculated using the life table method for patients diagnosed between 1985-1990; univariate differences in survival were compared using the Wilcoxon statistic, and multivariate analyses were performed using a Cox regression model. RESULTS: There were 4995 SBA cases reported to the NCDB between 1985-1995, 55% of which occurred in the duodenum, 18% in the jejunum, 13% in the ileum, and 14% in nonspecified sites. The overall 5-year DSS was 30.5%, with a median survival of 19.7 months. By multivariate analysis, factors significantly correlated with DSS included patient age, tumor site, disease stage, and whether cancer-directed surgery was performed. CONCLUSIONS: SBA is found most commonly in the duodenum, and patient DSS is reduced at this site compared with those patients with jejunal or ileal tumors. This reduction in survival was associated with a lower percentage of cancer-directed surgery. Patients age > 75 years had a reduced DSS and more duodenal tumors, and were less frequently treated by cancer-directed surgery than their younger counterparts. This study reflects the experience with SBA from a large cross-section of U.S. hospitals, allowing for the identification of prognostic factors and providing a reference with which results from single institutions may be compared.

National Cancer Data Base report on cancer of the head and neck: acinic cell carcinoma.

BACKGROUND: Management of acinic cell carcinoma is based on reports of small numbers of cases accrued over several decades. METHODS: The National Cancer Data Base (NCDB) identified 1353 cases of acinic cell carcinoma of the head and neck for the years 1985 to 1995. Chi square analyses of selected contingency tables and Wilcoxon regression analyses of selected survival stratifications are presented. RESULTS: Five-year survival was 83.3% (observed) and 91.4% (disease specific). Worse survival was associated with high grade (p < .0001), age greater or equal to 30 years (p = .0055), and the presence of metastatic disease (p < .0001). CONCLUSIONS: An aggressive subset of acinic cell carcinoma which is characterized by high grade and advanced stage rarely occurs in patients younger than 30 years old. Although better outcome was not statistically demonstrated for combined therapy, surgery with irradiation is the most common management in the United States for cases with regional metastases, high grade, and microscopic positive margins.

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

BACKGROUND: To employ patient-reported speech outcome data collected on head and neck cancer (HNC) surveys, there is a need to determine (1) the relationship of patient ratings to speech language pathologist (SLP) ratings and (2) whether patients' attitudes toward their speech are an important element of speech measurements. METHODS: Associations were analyzed between (1) patients' ratings of speech function on surveys and equivalent SLP ratings and (2) patients' ratings of speech function and their satisfaction with speech function. RESULTS: Patient-reported survey ratings were significantly associated with comparable SLP ratings. The associations were stronger for intelligibility than for voice quality. Patients' functional and attitudinal ratings were also significantly associated. The associations were relatively strong for composite speech items and intelligibility and moderate for voice quality. CONCLUSIONS: Patient-reported speech outcomes can be interpreted as being fairly equivalent to SLP evaluations. Attitudinal ratings appear to contribute an important aspect of the patients' perspective, with substantially different variances between function and attitude.

The National Cancer Data Base report on cutaneous and noncutaneous melanoma: a summary of 84,836 cases from the past decade. The American College of Surgeons Commission on Cancer and the American Cancer Society.

BACKGROUND: This study reviews the case-mix characteristics, management, and outcomes of melanoma cases occuring in the U.S. within the last decade. METHODS: Analyses of the National Cancer Data Base (NCDB) were performed on cases diagnosed between 1985 through 1994. A total of 84,836 cases comprised of cutaneous and noncutaneous melanomas were evaluated. RESULTS: The percentages of melanomas that were cutaneous, ocular, mucosal, and unknown primaries were 91.2%, 5.2%, 1.3%, and 2.2%, respectively. For cutaneous melanomas, the proportion of patients presenting with American Joint Committee on Cancer Stages 0, I, II, III, and IV were 14.9%, 47.7%, 23.1%, 8.9%, and 5.3%, respectively. Factors associated with decreased survival included more advanced stage at diagnosis, nodular or acral lentiginous histology, increased age, male gender, nonwhite race, and lower income. Multivariate analysis identified stage, histology, gender, age, and income as independent prognostic factors. For ocular melanomas, 85.0% were uveal, 4.8% were conjunctival, and 10.2% occurred at other sites. During the study period, there was a large increase in the proportion of ocular melanoma patients treated with radiation therapy alone. For mucosal melanomas, the distribution of head and neck, female genital tract, anal/rectal, and urinary tract sites was 55.4%, 18.0%, 23.8%, and 2.8%, respectively. Patients with lymph node involvement had a poor prognosis. For unknown primary melanomas, the distribution of metastases as localized to a region or multiple sites at presentation was 43.0% and 57.0%, respectively. Surgical treatment of patients with unknown primary site of the melanoma resulted in better survival compared with no treatment. CONCLUSIONS: Treatment of early stage cutaneous melanoma resulted in excellent patient outcomes. In addition to conventional prognostic factors, socioeconomic factors were found to be associated with survival.

Health states following head and neck cancer treatment: patient, health-care professional, and public perspectives.

BACKGROUND: This study investigated the assignment of preference values to health states which may follow head and neck cancer (HNC) treatment. Preference values for these health states were provided by HNC patients, HNC health-care providers, and a group of college students representing individuals with little knowledge of HNC. METHODS: A time trade-off technique was used by participants to assign preference values to four health states in the domains of appearance, eating, speech, breathing, pain, and work/social functioning. RESULTS: Patients' and health-care professionals' rank-ordered preference value scores for health states in appearance, breathing, eating, and speech were not significantly different (p < .05). These two groups differed significantly in ranking four of the eight pain and work/social functioning health states. Patients and students differed significantly in ranking 21 of the 24 health states (p < .05). CONCLUSIONS: Health-care professionals and patients had very similar perspectives regarding health states in the HNC-specific domains, indicating that these professionals appear to be a legitimate proxy for patients' attitudes in these domains. Healthcare professionals placed a significantly greater value on avoiding both pain and social confinement than did patients. Students, representing individuals naive regarding HNC, differed from patients and health-care professionals in their rankings of these health-state outcomes.

The National Cancer Data Base report on cancer of the head and neck.

BACKGROUND: The National Cancer Data Base (NCDB), a large sample of cancer cases accrued from hospital-based cancer registries, is sponsored by the Commission on Cancer of the American College of Surgeons and the American Cancer Society. The NCDB permits a detailed analysis of case-mix, treatment, and outcome variables. OBJECTIVE: To provide an overview of the contemporary status of the subset of patients with head and neck cancer in the United States. METHODS: The NCDB, which obtains data from US as well as Canadian and Puerto Rican hospitals, accrued 4 583 455 cases of cancer between 1985 and 1994. Of these cases, 301350 (6.6%) originated in the head and neck. We address 295022 cases of head and neck cancer limited to the 50 United States and District of Columbia. Cases were segregated into an earlier group (1985-1989) to permit 5-year follow-up and into a later group (1990-1994) to analyze a more contemporary group. Comparison between both periods permits identification of trends. RESULTS: The largest proportion of cases arose in the larynx (20.9%) and oral cavity, including lip (17.6%) and thyroid gland (15.8%). Squamous cell carcinoma (55.8%) was the most common histological finding, followed by adenocarcinoma (19.4%) and lymphoma (15.1%). Income level (low), race (African American), and tumor grade (poorly differentiated) were most notably associated with advanced stage. Treatment was most commonly surgery alone (32.4%), combined surgery with irradiation (25.0%), and irradiation alone (18.9%). Overall 5-year, disease-specific survival was 64.0%. Cancer of the lip demonstrated the best survival (91.1%) and cancer of the hypopharynx the worst survival (31.4%). CONCLUSIONS: This NCDB analysis of cancer of the head and neck provides a contemporary overview of head and neck cancer in the United States. It also serves to introduce a series of NCDB articles that address specific anatomical sites and histological types through separate, detailed analysis.

Risk factors for malignancy in adult tonsils.

BACKGROUND: Tonsillectomy in adults (age 18 years and older) is performed for a variety of conditions. The palatine tonsils may harbor carcinoma or lymphoma, and this potentially unanticipated finding may follow routine tonsillectomy in the adult. The ability to preoperatively identify adult tonsillectomy patients at increased risk for tonsillar malignancy could sensitize the clinician to this possibility and the potential need for expedited rather than routine tonsillectomy scheduling. METHODS: A retrospective review of 476 consecutive adult patients who underwent tonsillectomy during the last 10 years at the University of Iowa Hospitals and Clinics was undertaken. Proposed risk factors for tonsillar malignancy included a prior history of head and neck cancer, tonsillar asymmetry, palpable firmness or visible lesion in the tonsil, neck mass, unexplained weight loss, and unexplained constitutional symptoms. These risk factors were correlated with the pathologic diagnosis in the reviewed cases. RESULTS: Of these 476 patients, 25 had malignant tonsil pathology. No patient without risk factors was found to have malignancy on pathologic evaluation of the tonsils. Of the 25 patients with malignant tonsillar pathology, 23 had two or more risk factors, and 2 patients had one risk factor. Tonsillar asymmetry, found in 20 of the 25 cases, was the risk factor most frequently associated with malignant pathology. CONCLUSIONS: These results indicate that the presence of certain preoperatively identifiable risk factors are associated with the pathologic finding of malignancy in adult tonsillectomy specimens. Based on these criteria, a model which is predictive of the presence of tonsil malignancy may be constructed.

Associations between selected demographic parameters and dental status: potential implications for orodental rehabilitation.

PURPOSE: This pilot study evaluated potential relationships between dental status and various sociodemographic variables in the age group segment of the United States population at greatest risk for the disruption of dental function due to treatment of an oral cavity cancer. METHODS: The Dental Health Supplement of the 1989 National Health Interview Survey was used to evaluate the self-reported status of natural dentition and prior dental rehabilitation among the population of persons 45 years or older. RESULTS: Sociodemographic variables, which showed a significant association with status of natural dentition, were level of income and occupation at lower income levels (p < 0.05). Increased levels of prior dental rehabilitation were significantly associated with lower age, female gender, increased level of income, and occupation (p < 0.05). Occupations that required social interaction had the highest levels of both status of natural dentition and prior dental rehabilitation (p < 0.05). CONCLUSIONS: Overall dental status after treatment of oral cancer may be related to the occupational status of many persons. Sociodemographic factors that influence the dental rehabilitation needs of individual patients after treatment of an oral cancer should be considered in policy decisions affecting accessibility of dental rehabilitative care. A follow-up, survey study that would further define the identified relationships between a person's demographic status and dental rehabilitation needs is recommended.

Cost-identification analysis in oral cavity cancer management.

The objectives of this study were to investigate potential relationships between pretreatment patient-mix characteristics, treatment modalities, and costs generated during the pretreatment work-up, treatment, and 1-year follow-up periods for patients with oral cavity cancer (OCC). Another objective was to identify potential areas for cost reduction and improved resource allocation in the management of OCC patients. Using a retrospective cohort of 73 patients with OCC, pretreatment patient-mix characteristics and treatment modalities were evaluated in relation to university-based charges incurred during the pretreatment evaluation, treatment, and 1-year follow-up periods. Simple regression and stepwise multiple regression analyses were used to develop predictive models for cost based on independent variables, including age, AJCC TNM clinical stage, smoking history, American Society of Anesthesiologists (ASA) class, comorbidity as defined by the Kaplan-Feinstein grade and treatment modality. The dependent measurements included all physician, office, and hospital charges incurred at the University of Iowa Hospitals and Clinics during the pretreatment evaluation, treatment, and follow-up periods, as well as the total pretreatment through 1-year follow-up management costs. Independent variables that were identified as being significantly associated with treatment costs included T classification, N classification, TNM stage, unimodality versus multimodality treatment, and the Kaplan-Feinstein comorbidity grade. Age, smoking status, and ASA class were not significantly associated with costs. The majority of the OCC management costs were incurred during the treatment period. The most substantial decreases in management costs for OCC will be realized through measures that allow identification and treatment of disease at an early stage, in which single-modality treatment may effectively be used. Resource allocation for OCC should support the investigation of measures through which the diagnosis and treatment of OCC at the earliest possible stage is facilitated. The presence of comorbid illness is a significant component in the determination of management costs for OCC and should be included in analyses of resource allocation for OCC. The singular diagnosis of OCC encompasses a wide range of patient illness severity, and diagnosis-related reimbursement schemes for OCC treatment should optimally differentiate between early and advanced stage disease.

The National Cancer Data Base report on non-Hodgkin's lymphoma.

BACKGROUND: The National Cancer Data Base (NCDB) has reported on many malignancies occurring in men and women in the U. S. from >1400 contributing hospitals. The current report on non-Hodgkin's lymphoma (NHL) is a companion to an upcoming Patient Care Evaluation study of this relatively common and serious cancer. METHODS: This report is comprised of all NHL cases submitted to the NCDB divided into two diagnostic-year groups: 1985-1988 and 1990-1993. Variables routinely collected by hospital cancer registries have been analyzed to report on patterns of diagnosis and treatment. RESULTS: High grade NHL cases were more likely to be Stage IV (40.8%) than were low or intermediate grade cases (34.8% and 32.5%, respectively). Patients with NHL arising from lymph node sites tended to present with more advanced disease (55.8% with Stages III and IV disease), whereas patients with NHL arising from extranodal sites and non-lymph node nodal sites presented at an earlier stage (64.7% and 74.0%, respectively, with Stage I or Stage II disease). Approximately 67% of all patients underwent chemotherapy, whereas only 25% underwent surgery or radiation. By histology, 5-year survival was 68.8% for low grade disease, 51.9% for intermediate grade disease, and 45.8% for high grade disease; by stage, survival rates ranged from 73.5% for Stage I to 42.9% for Stage IV disease. CONCLUSIONS: To the authors' knowledge, the 91,306 cases in this study represent the largest contemporary sample of NHL patients. The material reported here may serve as a reference with which to compare local patterns with national data. The Working Formulation's ability to stratify patients' survival rates confirms its utility for NHL. Stage according to the American Joint Committee on Cancer also was accurate in predicting survival.

Baseline and post-treatment assessment of the general health status of head and neck cancer patients compared with United States population norms.

BACKGROUND: It is a common perception that the overall health of patients with head and neck cancer (HNC) is likely to be poor compared with the general population. This project was undertaken to investigate the pre- and post-treatment, global health status of HNC patients in comparison with age-matched, U.S. population norms using a self-administered general health status survey. METHODS: Between July 1, 1993, and May 1, 1996, 180 patients underwent pretreatment and 6 month follow-up evaluation with the standard version of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The SF-36 scale scores, means, standard deviations, and 95% confidence intervals were calculated for each SF-36 scale as well as for physical-health-component summary scores (PCS) and mental-health-component summary scores (MCS). Comparisons of these scores were made to U.S. population normative data. Pretreatment and 6-month follow-up SF-36 scores were compared. RESULTS: In the 45-54-year age group, all 8 SF-36 scale scores, the PCS, and MCS scores were significantly worse for the HNC patients in comparison with age-matched norms (p < .05). In the 55-64-year age group, the HNC patients were worse in 5 of the 8 SF-36 scale scores and the MCS score in comparison with age-matched norms (p < .05). In the 65-74-year age group, the HNC patients scored significantly worse in the mental health scale. In the comparison of pretreatment and 6-month follow-up scores, the HNC patients had significant decreases in the physical functioning scale (p = .003) and the PCS score (p = .047). The HNC patients showed significant improvement in the mental health scale (p = .049) and improvement in the bodily-pain scale, which approached significance (p = .053) at 6-month follow-up. The HNC patients showed a marked decrease in general health status with increasing stage of HNC. CONCLUSIONS: This work provides objective support for the perception that many HNC patients are initially seen for treatment with baseline health status functioning significantly below their age-matched contemporaries in the general population. An educated evaluation of global health outcomes following treatment in the HNC patient population must begin with an accurate pretreatment assessment of these parameters. Self-reported health-status assessment (HSA) is a useful means of evaluating global health status in this patient population.

Hypopharyngeal cancer patient care evaluation.

A survey was conducted to identify demographics and standards of care for treatment of hypopharyngeal squamous cell carcinoma in the United States. Data were accrued from voluntary submission of cancer registry and medical chart information from 769 hospitals representing 2939 cases diagnosed from 1980 to 1985 and 1990 to 1992. Clinical findings, diagnostic procedures employed, treatment practices, and outcome are presented. Overall, 5-year disease-specific survival was 33.4%, which segregated to 63.1% (stage I), 57.5% (stage II), 41.8% (stage III), and 22% (stage IV). Survival was best for patients treated with surgery only (50.4%), similar with combined surgery and irradiation (48%), and worse with irradiation only (25.8%). This analysis provides a standard to which current treatment practice and future clinical trials may be compared.
