Treatment of iron deficiency anemia and associated protein-losing enteropathy in children.

PURPOSE: The aims of this study were to evaluate the response of oral iron treatment in children with iron deficiency anemia (IDA) fed whole cow's milk (WCM) or soy formula; to compare the incidence of fecal blood loss in infants fed WCM and soy formula; and to evaluate the incidence and relation of protein-losing enteropathy (PLE) and IDA by testing serum albumin, fecal blood loss, and fecal alpha1-antitrypsin (alpha1AT). METHODS: Twenty-four children with nutritional IDA were randomly assigned to receive either 16 oz WCM or soy formula daily. Both groups were treated with daily therapeutic oral iron during 12 weeks. Stool specimens for hemoglobin losses were collected at weeks 0, 3, 6, and 12. Levels of serum albumin and fecal alpha1AT were tested at diagnosis and when IDA was corrected. RESULTS: Anemia was corrected in 21 of the 24 children by week 6 or 12. Median fecal hemoglobin losses were not increased in either group at diagnosis or during treatment. Seven of 24 children had PLE at diagnosis with elevated fecal alpha1AT levels of 72 to 381 mg/dL that returned to normal after correction of IDA. Their initial fecal alpha1AT levels averaged 170 mg/ dL at diagnosis and 21 mg/dL after the IDA was corrected. Excessive WCM intake of 30 oz/day or more was present in 63% of the infants. CONCLUSIONS: Treatment of nutritional IDA with oral iron was just as effective with a limited quantity of either WCM or soy formula. Fecal hemoglobin losses were uncommon and did not differ in children at diagnosis or during treatment of IDA. PLE associated with IDA resolves when the IDA is corrected, but differences between children fed WCM or soy formula could not be detected.

A hearing conservation program for Wisconsin youth working in agriculture.

Adolescents working in agricultural settings may be exposed to noise levels that result in hearing loss. The article describes the design, implementation, and results of a four-year, hearing conservation program (HCP) conducted at school. Thirty-four schools (753 students) were randomly assigned to either an intervention or control group. The intervention included multicomponent educational strategies and employed features of an industrial HCP. Final compliance surveys indicated 87.5% of intervention students reported using hearing protection devices (HPD) at least some of the time, compared to 45% of control students. The HCP components with the greatest reported influence were distribution of HPDs for use on the farm and yearly hearing tests. Eighty percent of intervention students reported intention to use HPDs in the future. It is feasible to conduct a hearing conservation program with junior high school and senior high school students, and it appears possible to persuade teen-agers to protect themselves from exposure to loud noise while working on a farm.

Resuscitation preferences among patients with severe congestive heart failure: results from the SUPPORT project. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments.

BACKGROUND: We sought to describe the resuscitation preferences of patients hospitalized with an exacerbation of severe congestive heart failure, perceptions of those preferences by their physicians, and the stability of the preferences. METHODS AND RESULTS: Of 936 patients in this study, 215 (23%) explicitly stated that they did not want to be resuscitated. Significant correlates of not wanting to be resuscitated included older age, perception of a worse prognosis, poorer functional status, and higher income. The physician's perception of the patient's preference disagreed with the patient's actual preference in 24% of the cases overall. Only 25% of the patients reported discussing resuscitation preferences with their physician, but discussion of preferences was not significantly associated with higher agreement between the patient and physician. Of the 600 patients who responded to the resuscitation question again 2 months later, 19% had changed their preferences, including 14% of those who initially wanted resuscitation (69 of 480) and 40% of those who initially did not (48 of 120). The physician's perception of the patient's hospital resuscitation preference was correct for 84% of patients who had a stable preference and 68% of those who did not. CONCLUSIONS: Almost one quarter of patients hospitalized with severe heart failure expressed a preference not to be resuscitated. The physician's perception of the patient's preference was not accurate in about one quarter of the cases. but communication was not associated with greater agreement between the patient and the physician. A substantial proportion of patients who did not want to be resuscitated changed their minds within 2 months of discharge.

Stimulant use and the potential for abuse in Wisconsin as reported by school administrators and longitudinally followed children.

The purpose of this study was to describe stimulant use and abuse as reported by school administrators and children diagnosed with attention deficit/hyperactivity disorder or attention deficit disorder inattentive. Five years after being identified as Ritalin responders, 161 children were surveyed regarding stimulant use and abuse. School principals in central Wisconsin were also surveyed regarding stimulant use and policies. No child believed stimulants as prescribed could lead to abuse. Sixteen percent of the children had been approached to sell, give, or trade their medication. During school hours, 44% of children and 37% of schools reported stimulants were stored unlocked. Not all schools had written policies regarding prescription drugs, and 10% permitted students to carry their own medication. Monitoring prescription usage, periodic reassessment of efficacy, and continuing education of family and teaching staff should be part of the multimodal treatment for this disorder. School policies should be developmentally sensitive.

Surgery without radiotherapy for primary treatment of endometrial cancer.

OBJECTIVE: To analyze the role of surgery alone, including pelvic and para-aortic lymphadenectomy, in patients with endometrial cancer who did not receive radiotherapy. METHODS: Between August 1987 and January 1997, 225 women with disease clinically confined to the uterus were staged surgically by a standard protocol that included pelvic and para-aortic lymphadenectomy in women with high risk factors. No radiation was administered before or after surgery. RESULTS: The combination of preoperative endometrial biopsy grade and gross depth of myometrial invasion identified 123 (55%) high-risk patients who had lymphadenectomy and 102 (45%) low-risk patients who did not. Eighteen (15%) high-risk patients had lymph node metastases and received postoperative systemic therapy. Three low-risk, eight high-risk-node-negative, and no high-risk-node-positive patients were diagnosed with recurrent cancer, corresponding to 5-year recurrence-free proportions of 0.95, 0.89, and 1.00, respectively. Although sample sizes and limited follow-up limit conclusions, the experience to date suggests a high rate of survival in all three groups. CONCLUSION: Our preliminary experience indicates that even high-risk patients have an excellent prognosis when treated with surgery, including pelvic and para-aortic lymphadenectomy, without radiotherapy.

Infections with nonthoracotomy implantable cardioverter defibrillators: can these be prevented? Endotak Lead Clinical Investigators.

Nonthoracotomy ICDs are believed to be the best therapeutic modality for treatment of life-threatening ventricular arrhythmias. Little is known about the risk of infection with initial implantation of these devices. We studied the incidence, clinical characteristics, and risk factors associated with infections in 1,831 patients with nonthoracotomy ICD from the Endotak-C nonthoracotomy lead registry of Cardiac Pacemakers, Inc. A transvenous lead was implanted in 950 patients (51.9%) and a combination transvenous plus subcutaneous patch was used in 881 patients (48.1%). Nine preselected data variables were studied, and all investigators identified as having patients with infections were personally contacted. Infections occurred in 22 (1.2%) of 1,831 patients receiving this nonthoracotomy ICD system. The mean time to infection was 5.7 +/- 6.5 months (range 1-25 months). Staphylococci were isolated in 58% of patients with reported infection. The presence of a subcutaneous defibrillator patch system was associated with the development of infection. Six of 950 patients (0.63%) with a totally transvenous lead system developed infection versus 16 of 838 (1.9%) patients with a transvenous lead plus subcutaneous patch system configuration (P = 0.015, Chi-square test), with an unadjusted estimated odds ratio of 3.06 (CI 1.19-7.86). The risk of infection encountered with the nonthoracotomy ICD is low, estimated from our data to be 1.2%. Placement of a subcutaneous defibrillator patch appears to be an independent risk factor for development of infection.

Quality of data regarding diagnoses of spinal disorders in administrative databases. A multicenter study.

The purpose of the present study was to evaluate the accuracy of data regarding diagnoses of spinal disorders in administrative databases at eight different institutions. The records of 189 patients who had been managed for a disorder of the lumbar spine were independently reviewed by a physician who assigned the appropriate diagnostic codes according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). The age range of the 189 patients was seventeen to eighty-four years. The six major diagnostic categories studied were herniation of a lumbar disc, a previous operation on the lumbar spine, spinal stenosis, cauda equina syndrome, acquired spondylolisthesis, and congenital spondylolisthesis. The diagnostic codes assigned by the physician were compared with the codes that had been assigned during the ordinary course of events by personnel in the medical records department of each of the eight hospitals. The accuracy of coding was also compared among the eight hospitals, and it was found to vary depending on the diagnosis. Although there were both false-negative and false-positive codes at each institution, most errors were related to the low sensitivity of coding for previous spinal operations: only seventeen (28 per cent) of sixty-one such diagnoses were coded correctly. Other errors in coding were less frequent, but their implications for conclusions drawn from the information in administrative databases depend on the frequency of a diagnosis and its importance in an analysis. This study demonstrated that the accuracy of a diagnosis of a spinal disorder recorded in an administrative database varies according to the specific condition being evaluated. It is necessary to document the relative accuracy of specific ICD-9-CM diagnostic codes in order to improve the ability to validate the conclusions derived from investigations based on administrative databases.

Optic nerve contact and compression by the carotid artery in asymptomatic patients.

PURPOSE: To estimate the frequency and clinical correlates of contact and compression of the intracranial optic nerve by the supraclinoid carotid artery in asymptomatic patients. METHODS: In a retrospective study, we identified asymptomatic patients who had undergone magnetic resonance imaging with sequences that could be used to evaluate the relation between the intracranial optic nerve and the carotid artery. These patients underwent neuroimaging evaluations for reasons unrelated to loss of vision, optic neuropathy, or carotid artery disorders. The relation between the optic nerve and carotid artery was graded in a standardized manner. The effect of a number of clinical covariates on the risk of compression was evaluated using multiple logistic regression. RESULTS: The frequencies of some of the artery-nerve relationships included contact of one or both optic nerves in 70 (70%) of 100 patients; bilateral compression in 12 (12%) of 100 patients; and unilateral compression with no arterial contact or compression on the opposite side in five (5%) of 100 patients. The estimated odds of compression were significantly increased as the diameter of the carotid artery increased. CONCLUSIONS: Among asymptomatic patients, supraclinoid carotid artery contact with the intracranial optic nerve occurs frequently. Anatomic compression, on the other hand, especially when unilateral, occurs infrequently. The risk of anatomic compression of the optic nerve is directly proportional to the diameter of the carotid artery.

Lack of overlap in genetic risks for Alzheimer's disease and Parkinson's disease.

We explored the question of genetic overlap between Alzheimer's disease (AD) and Parkinson's disease (PD) because evidence suggests clinical, pathologic, and epidemiologic overlap between the two disorders. We compared the frequency of AD and PD between the first-degree relatives of probands with AD and PD and first-degree relatives of spouse control subjects. Using life-table methods, we found increased risk of AD in first-degree relatives of patients with AD and an increased risk of PD in first-degree relatives of patients with PD. The risk of PD in first-degree relatives of patients with AD was not increased, nor was the risk of AD in first-degree relatives of patients with PD increased. These data do not support the hypothesis that important genetic overlap exists between AD and PD.

Pain and satisfaction with pain control in seriously ill hospitalized adults: findings from the SUPPORT research investigations. For the SUPPORT investigators. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatmentm.

OBJECTIVES: To evaluate the pain experience of seriously ill hospitalized patients and their satisfaction with control of pain during hospitalization. To understand the relationship of level of pain and dissatisfaction with pain control to demographic, psychological, and illness-related variables. DESIGN: Prospective, cohort study. SETTING: Five teaching hospitals. PATIENTS: Patients for whom interviews were available about pain (n = 5,176) from a total of 9,105 patients in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients were interviewed after study enrollment about their experiences with pain. When patients could not be interviewed due to illness, we used surrogate (usually a family member) responses calibrated to patient responses (from the subset of interviews with both patient and surrogate responses). Ordinal logistic regression was used to study the association of variables with level of pain and satisfaction with its control. Nearly 50% of patients reported pain. Nearly 15% reported extremely severe pain or moderately severe pain occurring at least half of the time, and nearly 15% of those patients with pain were dissatisfied with its control. After adjustment for confounding variables, older and sicker patients reported less pain, while patients with more dependencies in activities of daily living, more comorbid conditions, more depression, more anxiety, and poor quality of life reported more pain. Patients with colon cancer reported more pain than patients in other disease categories. Levels of reported pain varied among the five hospitals and also by physician specialty. After adjustment for confounding variables, dissatisfaction with pain control was more likely among patients with more severe pain, greater anxiety, depression, and alteration of mental status, and lower reported income; dissatisfaction with pain control also varied among study hospitals and by physician specialty. CONCLUSIONS: Pain is common among severely ill hospitalized patients. The most important variables associated with pain and satisfaction with pain control were patient demographics and those variables that reflected the acute illness. Pain and satisfaction with pain control varied significantly among study sites, even after adjustment for many potential confounders. Better pain management strategies are needed for patients with the serious and common illnesses studied in SUPPORT.

Prognostic significance of gross myometrial invasion with endometrial cancer.

OBJECTIVE: To determine if intraoperative estimation of gross myometrial invasion is sufficiently precise to guide surgical aggressiveness in staging patients with endometrial cancer. METHODS: Between September 1987 and September 1995, 236 women with endometrial cancer had visual estimation of gross myometrial invasion during surgical staging which included pelvic and para-aortic lymphadenectomy. RESULTS: In 213 patients (90.3%), the depth of gross myometrial invasion correctly predicted the microscopic depth of invasion on permanent histopathologic sections. Statistically significant associations were found between gross depth of myometrial invasion and tumor grade (P < .001), histopathology (P = .014), cervical metastases (P < .001), adnexal metastases (P < .001), omental metastases (P < .001), malignant pelvic cytology (P < .001), pelvic lymph node metastases (P < .001), para-aortic lymph node metastases (P = .001), and surgical stage (P < .001). Patients with more than 50% gross myometrial invasion were more likely to have poorly differentiated malignancies; nonendometrial histologies; malignant pelvic cytology; higher surgical stage; and cervical, adnexal, omental, pelvic lymph node, and para-aortic lymph node metastases. Patients with more than 50% gross myometrial invasion had a 6.4-fold higher prevalence of pelvic lymph node metastases, a 6.9-fold higher prevalence of para-aortic lymph node metastases, and a 6.7-fold higher prevalence of advanced surgical stage than patients with less than 50% myometrial invasion. CONCLUSION: Patients with endometrial cancer and more than 50% myometrial invasion on gross visual intraoperative estimation are at marked risk for extrauterine metastases, including pelvic and para-aortic lymph node metastases. Such patients should be considered for more aggressive surgical staging, including pelvic and para-aortic lymphadenectomy.

Generalizability of clinical studies conducted at tertiary care medical centers: a population-based analysis.

The Marshfield Epidemiologic Study Area (MESA), a geographically defined population registry at one of the participating sites in SUPPORT (a multicenter study of the care of seriously ill hospitalized patients) permitted assessment of generalizability in that study. On the basis of age- and sex-specific rates of enrollment of SUPPORT patients in MESA, we estimate that about 400,000 patients per year would fulfill SUPPORT eligibility criteria in the United States. However, an estimated 925,000 patients, particularly the elderly and those with impairments in their activities of daily living (ADLs), have SUPPORT-like illnesses annually, but do not receive the aggressive care required for study enrollment. The absence of patients not interested in aggressive care in tertiary care-based studies is compounded by the overrepresentation of patients referred from distant areas to the tertiary care center. Such patients tended to be older and to have different diseases than patients in MESA. Care should be taken in generalizing results from clinical and epidemiologic studies conducted at tertiary care centers.

Race, resource use, and survival in seriously ill hospitalized adults. The SUPPORT Investigators.

OBJECTIVE: To examine the association between patient race and hospital resource use. DESIGN: Prospective cohort study. SETTING: Five geographically diverse teaching hospitals. PATIENTS: Patients were 9,105 hospitalized adults with one of nine illnesses associated with an average 6-month mortality of 50%. MEASUREMENTS AND MAIN RESULTS: Measures of resource use included: a modified version of the Therapeutic Intervention Scoring System (TISS); performance of any of five procedures (operation, dialysis, pulmonary artery catheterization, endoscopy, and bronchoscopy); and hospital charges, adjusted by the Medicare cost-to-charge ratio per cost center at each participating hospital. The median patient age was 65; 79% were white, 16% African-American, 3% Hispanic, and 2% other races; 47% died within 6 months. After adjusting for other sociodemographic factors, severity of illness, functional status, and study site, African-Americans were less likely to receive any of five procedures on study day 1 and 3 (adjusted odds ratio [OR] 0.70; 95% confidence interval [CI] 0.60, 0.81). In addition, African-Americans had lower TISS scores on study day 1 and 3 (OR -1.8; 95% CI-1.3, -2.4) and lower estimated costs of hospitalization (OR (-)$2,805; 95% CI (-)$1,672, (-)$3,883). Results were similar after adjustment for patients' preferences and physicians' prognostic estimates. Differences in resource use were less marked after adjusting for the specialty of the attending physician but remained significant. In a subset analysis, cardiologists were less likely to care for African-Americans with congestive heart failure (p < .001), and cardiologists used more resources (p < .001). After adjustment for other sociodemographic factors, severity of illness, functional status, and study site, survival was slightly better for African-American patients (hazard ratio 0.91; 95% CI 0.84, 0.98) than for white or other race patients. CONCLUSIONS: Seriously ill African-Americans received less resource-intensive care than other patients after adjustment for other sociodemographic factors and for severity of illness. Some of these differences may be due to differential use of subspecialists. The observed differences in resource use were not associated with a survival advantage for white or other race patients.

Epidemiologic research in an integrated regional medical care system: the Marshfield Epidemiologic Study Area.

To capitalize on Marshfield Clinic's advantages for population-based health research, we developed the Marshfield Epidemiologic Study Area (MESA). Marshfield Clinic is an integrated system consisting of a large multispecialty clinic and 23 affiliated clinics. Clinic physicians provide virtually all of the medical care, both inpatient and outpatient, for residents of the area. MESA consists of 14 ZIP codes in which over 95% of the 50,000 residents and most significant health events are captured in Marshfield Clinic databases, including all deaths, 94% of hospital discharges, and 92% of medical outpatient visits. MESA exemplifies the research potential of integrated medical care systems and the efforts required to realize that potential. Because it is representative of a defined population and provides an unselected sample of patients, MESA is well suited for epidemiologic research and research elucidating the clinical spectrum and natural history of diseases and the effectiveness of treatment.

Early progression of ophthalmoplegia in patients with ischemic oculomotor nerve palsies.

OBJECTIVE: To describe the frequency and clinical correlates of early progression of ophthalmoplegia in patients with ischemic oculomotor nerve palsies. DESIGN: Cohort survey, case series. SETTING: Multispecialty clinic providing primary, secondary, and tertiary care in central and northern Wisconsin. PATIENTS: Sixteen patients evaluated within 1 week of the reported onset of ischemic oculomotor nerve palsy were identified and followed up prospectively using a standardized ophthalmoplegia grading scheme. All patients were followed up serially until their ophthalmoplegia resolved. MAIN OUTCOME MEASURES: Descriptive analysis of the temporal course of ophthalmoplegia and frequency of progression of deficits. Comparison between the group that had progression of ophthalmoplegia with the group that did not for age, hematocrit, cholesterol level, and adiposity; presence of diabetes, hypertension, hypercholesterolemia, and coronary artery disease; history of stroke; and tobacco use. RESULTS: Eleven (69%) of 16 patients had progression of ophthalmoplegia. The median time between reported onset and peak severity of ophthalmoplegia was 10 days. The only important difference between the progressive and nonprogressive groups was a shorter time to resolution of ophthalmoplegia for the nonprogressive group. CONCLUSIONS: Early progression of ophthalmoplegia occurs often in patients with ischemic oculomotor nerve palsies. The power to find differences between progressive and nonprogressive groups was limited by the small number of patients available for analysis.

Comparison of D&C and office endometrial biopsy in predicting final histopathologic grade in endometrial cancer.

OBJECTIVE: To compare the accuracy of D&C and office Z-sampler endometrial biopsy in predicting hysterectomy tumor grade in women with endometrial cancer. METHODS: Between September 1987 and July 1994, 183 women with endometrial cancer had D&C or office Z-sampler endometrial biopsy before hysterectomy. RESULTS: One hundred thirty-one patients (72%) had Z-sampler biopsies and 52 (28%) had D&C. The Z-sampler correctly identified the hysterectomy tumor grade in 76 of 131 patients (58%), compared with 40 of 52 (77%) with D&C, a significant difference (P = .024). The major difference observed was an increased fraction of lesions undergraded (ie, a lower grade tumor found in the biopsy than in the hysterectomy specimen) by the Z-sampler (34 of 131, 26%) versus D&C (five of 52, 10%). CONCLUSION: Dilation and curettage was more accurate in identifying hysterectomy tumor grade and less likely to miss a higher-grade tumor than was Z-sampler biopsy. However, the inaccuracy of D&C alone necessitates further preoperative and intraoperative assessment for other risk factors to determine the aggressiveness with which an individual patient should be staged surgically.

Surrogates' predictions of seriously ill patients' resuscitation preferences.

BACKGROUND: Seriously or terminally ill patients are frequently incapacitated and unable to express their preferences regarding cardiopulmonary resuscitation (CPR). In this situation, family members or other surrogate decision makers are often asked whether they believe the patient would want to be resuscitated. We evaluated the concordance of patient CPR preferences and surrogate perceptions of the patient preferences in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT), a large, multicenter study of seriously ill hospitalized patients. METHODS: We compared patient preferences and surrogate perceptions in 1226 pairings in which both patient and surrogate responded to CPR decision questions. We also examined factors that might influence patient-surrogate concordance. RESULTS: Twenty-nine percent of patients with paired data did not want to be resuscitated; 26% of surrogates did not believe the patient they represented would want to be resuscitated. Within pairs, the overall exact agreement with respect to CPR decisions was 74%. For patients favoring CPR, only 16% of the surrogates misconstrued the patient's wishes. For patients who did not want to be resuscitated, however, 50% of the surrogates did not reflect the patient's wishes. If patients reported telling surrogates their CPR preference, concordance was significantly improved if the surrogate believed the patient did not want to be resuscitated and was significantly worsened if the surrogate believed the patient wanted CPR. This finding is likely an artifact of patients being more likely to report their preference to surrogates if that preference was not to be resuscitated. CONCLUSIONS: Surrogates' perceptions of patient CPR preferences are often inaccurate, particularly for those patients who do not want to be resuscitated. Methods to improve communication between patients and surrogates on CPR preferences should be developed and evaluated.

Health values of the seriously ill. SUPPORT investigators.

OBJECTIVE: To assess 1) the health values and health ratings of seriously ill hospitalized patients, their surrogate decision makers, and their physicians; 2) the determinants of health values; and 3) whether health values change over time. DESIGN: Prospective, longitudinal, multicenter study. SETTING: 5 academic medical centers. PARTICIPANTS: 1438 seriously ill patients with at least one of nine diseases who had a projected overall 6-month mortality rate of 50%; their surrogates; and their physicians. MEASUREMENTS: Time-tradeoff utilities (reflecting preferences for a shorter but healthy life) and health ratings. RESULTS: At study day 3, patients had a mean time-tradeoff utility of 0.73 +/- 0.32 (median [25th, 75th percentile], 0.92 [0.63, 1.0]), indicating that they equated living 1 year in their current state of health with living 8.8 months in excellent health. However, scores varied widely; 34.8% of patients were unwilling to exchange any time in their current state of health for a shorter life in excellent health (utility, 1.0), and 9.0% were willing to live 2 weeks or less in excellent health rather than 1 year in their current state of health (utility, 0.04). Health rating scores averaged 57.8 +/- 24.0 (median [25th percentile, 75th percentile], 60 [50, 75]) on a scale of 0 (death) to 100 (perfect health). The patients' mean time-tradeoff score exceeded that of their paired surrogates (n = 1041) by 0.08 (P < 0.0001). Time-tradeoff scores were related to psychosocial well-being; health ratings; desire for resuscitation and extension of life rather than relief of pain and discomfort; degree of willingness to live with constant pain; and perceived prognosis for survival and independent functioning. Scores of surviving patients increased by an average of 0.06 after 2 months (P < 0.0001) and 0.08 after 6 months (P < 0.0001). CONCLUSIONS: Health values of seriously ill patients vary widely, are higher than patients' surrogates believe, are related to few other preference and health status measures, and increase over time.

Prognostic significance of malignant cervical cytology in patients with endometrial cancer.

OBJECTIVE: To determine the prognostic importance of malignant cervical cytology before surgical stating in patients with endometrial cancer. METHODS: Between September 1987 and August 1993, 164 patients with endometrial cancer had preoperative cervical cytology examined before surgical staging, which included pelvic and para-aortic lymphadenectomy. RESULTS: Ninety-four patients (57.3%) had normal cervical cytology, 21 (12.8%) had atypical cytology suspicious for malignancy, and 49 (29.9%) had malignant cytology on preoperative cervical cytology. Statistically significant associations were found between cervical cytology and histopathology (P = .017), tumor grade (P = .001), cervical metastases (P < .001), surgical stage (P = .035), pelvic lymph node metastases (P = .016), and para-aortic lymph node metastases (P = .006). Patients with malignant cytology were more likely to have non-endometrioid histology, poorly differentiated malignancies, higher surgical stage, and cervical, pelvic lymph node, and para-aortic lymph node metastases. Patients with malignant cervical cytology had a 3.5 times higher prevalence of pelvic lymph node metastases and a five times higher prevalence of para-aortic lymph node metastases than patients with normal cytology. No association was found between preoperative cervical cytology and the depth of myometrial invasion, adnexal metastases, omental metastases, or malignant pelvic peritoneal cytology. CONCLUSIONS: Patients with endometrial cancer and malignant preoperative cervical cytology are at marked risk for extrauterine metastases, including pelvic and para-aortic lymph node metastases. Such patients should be considered for primary surgical staging, including pelvic and para-aortic lymphadenectomy.

Comparison of the Z-sampler and Novak endometrial biopsy instruments for in-office diagnosis of endometrial cancer.

The purpose of this study was to compare the diagnostic accuracy and specimen adequacy of in-office endometrial biopsies taken with the Novak curette and with a disposable flexible polypropylene biopsy device, the Z-sampler, in patients with endometrial cancer. Eighty women with endometrial cancer had in-office endometrial biopsies performed with the Z-sampler and the Novak curette prior to hysterectomy. The Z-sampler diagnosed 66 (82.5%) with endometrial cancer compared to 68 (85%) with the Novak curette (P = 0.724). The Z-sampler biopsies included 10 specimens (12.5%) pathologically inadequate for diagnosis, compared to 5 (6.3%) Novak curette biopsies inadequate for diagnosis (P = 0.074). When both endometrial biopsies were adequate for pathologic evaluation, the Z-sampler diagnosed 66 of 70 women (94.3%) with endometrial cancer, compared to 64 of 70 (91.4%) diagnosed with the Novak curette (P = 0.617). We did not demonstrate a significant difference in diagnostic accuracy or specimen adequacy between in-office biopsies taken with the Novak curette and those taken with the Z-sampler in patients with endometrial cancer.
