Use of gastroprotective agents in recommended doses in hospitalized patients receiving NSAIDs: a drug utilization study.

OBJECTIVE: In recent years, studies investigated to what extend recommendations for co-prescribing gastroprotective agents in prevention of NSAID-induced gastrointestinal complications are followed in clinical practice. However, only a few studies have also taken into consideration the recommended dose of gastroprotectives prescribed in NSAID-induced ulcer prophylaxis. The aim of our study was to evaluate the prevalence of concomitant use of gastroprotectives with NSAIDs in hospitalized patients, with emphasis on the recommended dose of gastroprotectives for ulcer prophylaxis. METHOD: This observational, cross-sectional, drug utilization study included all adult patients receiving NSAIDs hospitalized in the Clinical Hospital Center Zagreb on the day of the study. Data on age, sex, comorbidities, indications for NSAID use, type/dose of NSAIDs and gastroprotectives, history of gastrointestinal events, active gastrointestinal symptoms and risk factors were evaluated. MAIN OUTCOME MEASURE: Study outcomes were: (1) prevalence of prescription of gastroprotectives among NSAID-users at risk; (2) prevalence of prescription of gastroprotective in recommended dose; (3) association between risk factors and prescription of GPAs. RESULTS: The rates of gastroprotectives prescription were significantly higher in NSAID-users with concomitant risk factors as compared to patients without risk factors [47/70 (67.1%) and 8/22 (36.4%), respectively; p=0.01072]. However, gastroprotection in recommended ulcer-preventive dose was low in both groups [8/70 (11.4%) and 9/92 (9.8%), respectively]. The number of concomitant risk factors did not increase the odds of receiving anti-ulcer therapy (odds ratio 0.7279). Thirty-three percent of patients with concomitant risk factors were not prescribed gastroprotectives. Ibuprofen, NSAID with the lowest risk of inducing gastrointestinal complications, was prescribed in only two patients. CONCLUSION: The results indicate high awareness among hospital physicians about possible NSAID-induced gastrointestinal complications, but insufficient knowledge about risk factors related to NSAID-induced gastrointestinal toxicity, recommended dose of gastroprotectives in NSAID-induced ulcer prophylaxis and gastrointestinal toxicity of different types of NSAIDs.

Feeding practices and nutrition recommendations for infants with cystic fibrosis.

Cystic fibrosis (CF) is an autosomal recessive disease characterized clinically by recurrent respiratory tract infections and malabsorption caused by pancreatic insufficiency. Typically diagnosed during infancy or childhood, CF impairs weight gain and growth, increases susceptibility to infection, and decreases longevity. Until recently, no guidelines for infant feedings were available. A consensus report prepared through the Cystic Fibrosis Foundation summarizes guidelines for the optimal nutrition management of patients with CF. This study identified current feeding practices and nutrition recommendations of dietitians who treat infants with CF and compared them with the recommendations of the consensus report. A survey was developed and sent to dietitians (n = 130) who work in accredited cystic fibrosis centers. Eighty-six dietitians (66%) responded after two mailings, and 75 usable surveys were analyzed. The survey investigated practitioners' recommendations for infant formulas, energy intake, nutritional supplements, and pancreatic enzyme supplementation. Protein hydrolysate infant formulas were recommended by most respondents (69%). Energy intake greater than 130% of the Recommended Dietary Allowances (RDAs) was recommended for well-nourished infants with CF and greater than 140% of the RDAs for malnourished infants with CF at 1 year of age. Formula additives, including fat and carbohydrate modules, were used by all respondents and were frequently added to infant foods to increase caloric density. Enteric coated pancreatic enzymes were used by the majority (76%) of dietitians. These findings indicate that most dietitians follow the nutrition guidelines established by the Cystic Fibrosis Foundation consensus report for goals for energy and protein intake, use of nutritional supplements, and replacement of pancreatic enzymes in infants with CF.

A review of machine-guarding recommendations.

A series of machine-guarding drawings were developed during the 1940s, which represent the relationship between gap size and safe distance. Since the development of these drawings, larger and more comprehensive anthropometric surveys have been conducted, but they have never been compared with the drawings. The purpose of this investigation was to determine whether these original recommendations presented in the drawings are still consistent with data in the larger anthropometric surveys, especially relating to women and minorities, who are now much more prevalent in the American workplace. In this study, data from six anthropometric surveys were compared with the original machine-guarding recommendations. To minimize the percentage of the population at risk, the length dimensions were chosen from the 99th percentile male population, and thickness dimensions were chosen from the 1st percentile female population. Many of these recommendations were found to be valid, although several important modifications were suggested. Several currently recommended dimensions show no correlation to the incompressible joints utilized in this study, and it is recommended that they be eliminated. The recommendations are presented in tables of maximum gap size and minimum distance.

Recommendations for the performance of UDS tests in vitro and in vivo.

The Working Group (WG) dealt with the harmonization of routine methodologies of tests for unscheduled DNA synthesis (UDS) both in vitro and in vivo. In contrast to the existing guidelines from OECD, EPA and EC on in vitro UDS tests (there is no Japanese UDS guideline), the Working Group recommends that in general in vitro UDS tests should be performed with primary hepatocytes. For routine applications any other cell types would need special justification. Hepatocytes from male rats are preferable, unless there are contra-indications on the basis of e.g. toxicokinetic data. According to the OECD, EPA and EC guidelines, UDS may be analysed by means of autoradiography (AR) or liquid scintillation counting (LSC). The WG recommends use of AR. LSC is less suitable due to the problem of differentiation between UDS activity and replicative DNA synthesis, and the disadvantage that cells cannot be analysed individually. Since a specific cell type was recommended by the WG, methodological aspects could be described in more detail than in the present guidelines. For in vitro tests, it was agreed that the initial viability of freshly isolated hepatocytes should be at least 70%. With regard to the need for confirmatory experiments in the event of a clear-cut negative result, the majority view was that confirmation by a second (normally not identical) experiment is still needed; this is in line with the present OECD and EC guidelines. Evaluation of results from UDS tests should be based primarily on net nuclear grain (NNG) values, although it is recognised that nuclear and cytoplasmic grains result from different biological processes. Since grain counts are influenced by a number of methodological parameters, no global threshold NNG value can be recommended for discrimination of positive and negative UDS results. For in vitro assays, the criteria for positive findings go beyond those of the present guidelines and two alternative approaches are given which are based on (1) dose-dependent increases in NNG values and (2) reproducibility, dose-effect relationship and cytotoxicity. At present there is no official guideline on the performance of in vivo UDS tests. Some fundamental recommendations given for in vitro methodology also apply to the in vivo assay. For routine testing with the in vivo UDS test, again the general use of hepatocytes from male rats is recommended. However, concerning the requirement to use one or two sexes, consistency with other in vivo genotoxicity assays (e.g. the micronucleus assay) would be preferable. As for the in vitro methodology, AR is preferred rather than LSC.(ABSTRACT TRUNCATED AT 400 WORDS)

Laboratory variables and stratification of metastatic colorectal cancer patients: recommendations for therapeutic trials and for clinical practice guidelines.

OBJECTIVE: To identify, through a systematic review of the literature, the laboratory variables that, in addition to performance status and to the degree of tumor invasion, would allow a more accurate stratification of metastatic colorectal cancer patients who participate in chemotherapy trials, with or without radiotherapy. SECONDARY AIM: To compare the results of our systematic review with the recommendations made in current clinical practice guidelines, and with the results of related systematic reviews. METHODS: Update of two recently published systematic reviews, without metaanalysis, following the recommendations of the International Federation of Clinical Chemistry and Laboratory Medicine, and taking into account the Consolidated Standards of Reporting Trials statement. RESULTS: Of 877 publications retrieved, reasonable exclusion and inclusion criteria allow us to include 15 studies in our systematic review, thus confirming the low quality of clinical research in laboratory medicine. Four variables were most often found "significant" in multivariate statistical analysis: pretherapeutic levels of laboratory tests (13/15, 87%), degree of tumor invasion (9/13, 69%), treatment, or response to treatment (6/9, 67%), and performance status (8/13, 62%). The laboratory variable whose measurements are quite often recommended in the 10 clinical practice guidelines or in the four related systematic reviews that we retrieved are carcinoembryonic antigen (CEA), and liver function tests to a lesser extent. CONCLUSIONS: Available evidence supports the recommendation that in all metastatic colorectal cancer patients who participate in therapeutic trials, the following pretreatment laboratory variables should be systematically measured: blood cell counts, and haemoglobin, plasma prothrombin time, serum alkaline phosphatase (ALP), lactate dehydrogenase, transaminases, albumin, bilirubin, and CEA. If other tests were to be added, gamma glutamyl transferase, and erythrocyte sedimentation rate might perhaps be proposed. Further studies would be necessary to support the addition to this list, of other tests [e.g., cancer antigen (CA) 19-9]. Rather than using laboratory variables according to arbitrary thresholds, it seems recommendable to use them as continuous variables, and if possible, in terms of kinetics. Many clinical practice guidelines do not use levels of evidence in order to grade the strength of their recommendations, but rather seem to be based on experts opinions which are not always in agreement with the results of systematic reviews.

Adjuvant treatment recommendations in older women with breast cancer: a survey of oncologists.

OBJECTIVE: Previous studies demonstrate differing treatment patterns between older and younger patients with breast cancer. To explore the reasons for these disparities we conducted a survey of 28 oncologists specializing in breast cancer. DESIGN AND METHODS: Twenty-eight medical oncologists from Memorial Sloan-Kettering Cancer Center and the University of California Los Angeles who specialize in the treatment of breast cancer were asked to provide adjuvant treatment recommendations in hypothetical scenarios featuring older patients with high-risk breast cancer. For each of these hypothetical patients, the patient's age was varied over four possible values (70, 75, 80, or 85 years of age) and health and functional status varied across three possible states (perfect health, average health, or major health problems). Survey data were compiled and analyzed to determine the impact of theoretical patient age, baseline health, and functional status on their treatment recommendations. RESULTS: The proportion of oncologists who recommended adjuvant chemotherapy decreased as the patient's age increased or as the patient's functional status and health status decreased. For 96% of physicians (95% CI, 82-100%), patient age influenced chemotherapy recommendations, controlling for health/functional status; the same proportion of respondents were influenced by health/functional status, controlling for patient age. There was increased variability in treatment recommendations as the patient's age increased or functional status and health status decreased. CONCLUSION: Among these medical oncologists who primarily treat breast cancer adjuvant treatment recommendations vary based on patient age, health, and functional status. Future studies are needed to correlate age, health, and functional status with the risks and benefits of adjuvant therapy so that consensus guidelines can be formed. A more comprehensive baseline assessment of the older patient, such as can be derived from a comprehensive geriatric assessment may be useful in this regard.

Great expectations: factors influencing patient expectations and doctors recommendations at a Mood Disorders Unit.

BACKGROUND: Literature about expectations and management of depression within community samples reflects attitudes of people who have generally not received treatment. We examined the factors influencing treatment expectations and psychiatrists' treatment recommendations for patients referred to a mood disorders unit with identified episodes of major depression. METHODS: Prior to attending a mood disorders unit, 182 men and women who met DSM-III-R or DSM-IV criteria for current major depression provided data on sociodemographic details, history of medical and psychiatric illness and expectations of treatment. Psychiatrists' treatment recommendations to the referring clinician were assessed to determine whether the patients' initial expectations were met. RESULTS: Data analyses revealed three factors relating to patients' expectations: "enhanced coping", "providing fresh ideas for the referring doctor" and "providing fresh ideas to self". Patients' expectations were influenced by sociodemographic and illness-related characteristics. In particular, young female patients typically expected to receive strategies to enhance coping, while those with lifetime anxiety expected less active involvement on their part. Some clinicians' recommendations were dependent upon depression type and patient factors. Women and those with a history of anxiety disorders received more education and recommendations for relationship counselling and support groups. LIMITATIONS: The study design did not allow determination of the impact of patients' expectations on the psychiatrists' recommendations. CONCLUSIONS: Individual and illness characteristics are important predictors of treatment expectations prior to specialist care. It appears that doctors take these factors into account with implications for patients' satisfaction with the type of care recommended.

Adherence to the food guide pyramid recommendations among African Americans and Latinos: results from the Multiethnic Cohort.

The objective of the study was to determine the degree of adherence to the Food Guide Pyramid recommendations among African Americans, Latinos born in the United States, and Latinos born in Mexico. Subjects were from the Multiethnic Cohort Study in Hawaii and Los Angeles, and completed a self-administered quantitative food frequency questionnaire at baseline in 1993-1996. Dairy recommendations were the least likely of all the food group recommendations to be followed, with 61% to 99% of individuals in the three ethnic groups not consuming the recommended number of servings. African Americans were less likely to adhere to all of the food group recommendations compared to the two Latino groups. A greater percentage of Latinos born in the United States did not adhere to the food group recommendations compared to Latinos born in Mexico. All three groups would benefit from interventions designed to promote healthy food choices.

Physician perspectives to inform a new recommendation for meningococcal conjugate vaccine (MCV4).

PURPOSE: In January 2005, the U.S. Food and Drug Administration licensed a new tetravalent meningococcal conjugate vaccine (MCV4). Before any policy decisions by the U.S. Advisory Committee on Immunization Practices (ACIP) related to MCV4, the Centers for Disease Control and Prevention requested a study to explore the perspective of primary care physicians regarding different recommendation scenarios for use of MCV4. METHODS: Cross-sectional mail survey of a national random sample of pediatricians (PDs) and family physicians (FPs), conducted January 2005. Respondents chose from four MCV4 recommendation scenarios in terms of ability to implement, perceived patient/parent preferences, scientific evidence, and overall best fit. RESULTS: Response rate to the single-mailing survey was 57%. In terms of ability to implement, respondents generally preferred an MCV4 recommendation targeted to middle-school entry (11-12 years old) or with the Td booster at any age, but on the basis of scientific evidence they favored MCV4 at high school completion. For "overall best fit," relatively equal proportions of respondents favored a recommendation at middle school entry and one linked to Td booster administration (whenever it occurred); there were no significant differences between PDs and FPs. Major influences on willingness to recommend MCV4 were vaccine safety/side effects and insurance coverage/reimbursement. CONCLUSIONS: Support for an MCV4 recommendation at middle school entry is common but not universal among primary care providers. Data suggest that respondents appreciate the potential discrepancy between practical aspects of vaccine delivery and the need to protect those adolescents at greatest risk of disease. Respondents' preferences for the overall best fit appear to prioritize ease of implementation over epidemiologic patterns.

Role and modalities of information and education in the management of patients with rheumatoid arthritis: development of recommendations for clinical practice based on published evidence and expert opinion.

OBJECTIVES: To develop recommendations for the information and education of patients with rheumatoid arthritis (RA) seen in everyday practice, using evidence from the literature, supplemented with expert opinion when needed. METHODS: A scientific committee developed eight questions using the Delphi consensus procedure. A task force reviewed the literature for answers to these questions, using the PubMed Medline database (1980-2004) and the 2002-2004 databases of the annual meetings held by the French Society for Rheumatology (SFR), the European League Against Rheumatism (EULAR), and the American College of Rheumatology (ACR); the indexing terms for the search were rheumatoid, arthritis, patient, education, information, knowledge, general practitioner, family doctor, and continuing medical education. Only articles in French or English were included. A panel of rheumatologists used the evidence thus compiled to develop recommendations for each question; gaps in evidence were filled by calling on the panelists' expert opinion. For each recommendation, the level of evidence and extent of agreement among panelists were specified. RESULTS: There were four general questions about the objectives, supports, and mode of delivery (group or one-on-one) of patient information and education, as well as on evaluating knowledge, and four specific questions on program content. The search identified 1235 articles; 144 were selected on the title and 118 of those on the abstract. Three abstracts presented at meetings were also kept. The evidence from the literature was presented to the panelists during interactive workshops. The panelists then developed eight recommendations, all of which were grade D because no published studies specifically addressed everyday clinical practice. Agreement among panelists ranged across recommendations from 85.7% to 100%. CONCLUSION: Recommendations about educating and informing patients with RA in everyday practice were developed. They should increase practice uniformity and ultimately optimize the management of patients with RA.

Surgeon communication behaviors that lead patients to not recommend the surgeon to family members or friends: Analysis and impact.

BACKGROUND: This study analyzes specific elements of physician communication that lead patients to not recommend surgeons to family members or friends (FMoFs). METHODS: Patients completed questionnaires after surgery clinic encounters. Questionnaires addressed whether surgeons used optimal communication behaviors and whether patients would recommend the surgeon. RESULTS: A total of 1,514 questionnaires were completed for 39 surgeons. Patients reported the following communication lapses: failure to ask whether the patient had questions (6.9% of occasions), failure to sit down (6.5%), use of words patients could not understand (5%), failure to educate patients about their condition (4.3%), failure to introduce themselves (4%), lack of interest in patients as persons (2.4%), and inadequacies in answering questions (2%). Surgeons omitted at least one of these optimal behaviors in 16.3% of encounters. Surgeons were not recommended in 1.7% of encounters. Twelve surgeons (31%) were not recommended on at least 1 occasion. Behaviors omitted most commonly in encounters where patients wouldn't recommend surgeons included failure to show interest in the patient (52%), explain their medical condition (52%), invite questions (40%), and answer questions (36%). CONCLUSIONS: Extrapolating these results to 1,618 patient visits/surgeon/year, results in the following number of patients annually who do not recommend their surgeons: 15 for failure to adequately explain their medical condition, 15 for failure to show interest in them, 11 for failure to ask if the patient had questions, and 10 for failure to answer questions. Considering the ripple effect due to the number of a patient's FMoFs, surgeons should be aware of the significant impact of even occasional lapses in optimal communication behaviors.

Colorectal cancer screening: recommendations and guideline adherence by physicians from digestive endoscopy centers in the Lazio region, Italy.

INTRODUCTION: Endoscopy plays a key role in colorectal cancer screening; at the beginning of a mass screening campaign, it is important for public health officials to assess physicians' attitudes and adherence to guidelines regarding colorectal cancer screening. METHODS: In April 2004, a questionnaire was sent to all 80 digestive endoscopy centers in the Lazio region, identified by the annual census of the Italian Society of Digestive Endoscopy. The results were compared to those from a similar survey of general practitioners (GPs). RESULTS: Seventy-one centers (89%) returned the questionnaire. Only 3% of physicians said they did not recommend any colorectal cancer screening test. Colonoscopy was perceived as the most effective screening test and was the most recommended (80%). Fecal occult blood test was recommended by 61% of physicians and flexosigmoidoscopy by 11%. Endoscopy centers' physicians recommend screening more than GPs (96.9% vs. 78.3%), while they have a similar level of over-recommending (50.8% vs. 47.2%). Almost 95% of endoscopy physicians properly recommended colonoscopy after positive FOBT. CONCLUSIONS: Neither physicians at endoscopy centers nor GPs tend to follow screening guidelines. Screening programmes should not rely on a single medical specialist, but on interdisciplinary management of the disease to strengthen adherence to existing guidelines.

A national survey of primary care physicians' colorectal cancer screening recommendations and practices.

BACKGROUND: National data on providers' colorectal cancer (CRC) screening knowledge, attitudes, and practices are sparse. This study assessed primary care physicians' (PCPs') beliefs about the effectiveness of CRC screening, their recommendations for screening, their perceptions of the influence of published guidelines on their CRC screening recommendations, and how they conduct CRC screening in their clinical practices. METHODS: A questionnaire was administered to a nationally representative sample of practicing PCPs. Of 1718 eligible physicians, 1235 (72%) responded. RESULTS: Only 2% of PCPs said they did not recommend CRC screening. Over 80% indicated that they most often recommend CRC screening with fecal occult blood testing and/or flexible sigmoidoscopy, although colonoscopy was perceived as the more effective screening modality. Nearly two-thirds of obstetrician/gynecologists and one-fourth of other practitioners reported conducting fecal occult blood testing exclusively by digital rectal exam. Only 29% of PCPs said they perform sigmoidoscopy. Estimated volumes of ordering, performing, or referring for CRC screening were low, and <20% reported that three-fourths or more of their older patients were up to date with CRC screening as recommended by the physician. Many PCPs reported recommending CRC screening at nonstandard starting ages or too-frequent intervals. CONCLUSIONS: Awareness of CRC screening among PCPs in the United States is high. However, knowledge gaps about the timing and frequency of screening and suboptimal screening delivery were evident.

Evidence-based recommendations for the diagnosis and treatment of neovascular glaucoma.

PURPOSE: To succinctly update information on the pathogenesis, etiology, diagnosis, and treatment of neovascular glaucoma based on a systematic review of available literature and to provide summary recommendations rated for their importance to clinical outcome. CLINICAL RELEVANCE: Neovascular glaucoma is a devastating ocular disease that often results in loss of vision. The current standard of care includes retinal ablation and control of increased intraocular pressure with medical and surgical therapy. LITERATURE REVIEW METHODOLOGY: The authors conducted a MEDLINE literature search of articles published in English from 1966 to the present. Each article reviewed was rated as to the strength of evidence it provided, and summary ratings for the strength of evidence supporting clinical recommendations were generated. RESULTS: Level A (most important to patient outcome) recommendations for the diagnosis of neovascular glaucoma include a high index of suspicion, a full ocular examination including undilated gonioscopy, and pupil examination. In regard to treatment, Level A recommendations include treatment of the underlying disease origin, complete panretinal photocoagulation (if retinal ischemia is a factor), and medical control of both elevated intraocular pressure and inflammation. Level B recommendations (moderately important to patient outcome) encompass glaucoma surgery to control intraocular pressure when medical therapy is unsuccessful, although the ideal surgical procedure is unknown. Currently, trabeculectomy with antimetabolite therapy, aqueous shunt implants, and diode laser cyclophotocoagulation are the preferred surgical treatment options. CONCLUSIONS: The current literature on neovascular glaucoma has few articles that provide strong evidence in support of therapy recommendations (level I). Future research studies are needed to address areas in which the current evidence is moderately strong (level II) or weak, consisting only of a consensus of expert opinion (level III). Whenever practicable, these studies should be prospective, randomized clinical trials.

Reporting data following major trauma and analysing factors associated with outcome using the new Utstein style recommendations.

STUDY OBJECTIVE: To collect and present retrospectively the recommended core data from the Utstein style, analyse factors associated with outcome in major trauma, and discuss the value of the Utstein style definition of major trauma. DESIGN: A retrospective trauma cohort study. SETTING: A Norwegian trauma system with a 1200 bed combined local and referral trauma hospital without a formal trauma registry, covering a population of approximately 2.0 million. PARTICIPANTS: 3391 injured patients admitted 12 months from January 15, 1996. MAIN OUTCOME MEASURES: Recommended core data from the Utstein style, and factors associated with outcome defined as in-hospital death within 30 days. RESULTS: 225 patients had an injury severity score (ISS)>15. In each of the 225 patients, we were able to obtain at least 47% of the recommended core data. Age >70 years, fall as a mechanism of injury, and a Trauma Score (TS)< or =14 were significantly associated with poor outcome. Of 22 with no major trauma (ISS<16), two died in hospital and 20 had an intensive care unit stay of more than 2 days. CONCLUSION: We found it difficult to collect retrospectively the recommended core data of the Utstein style. Age and physiological alterations (TS) were significantly related to outcome. The recommended definition of major trauma (ISS>15) did not cover all life-threatening injuries. The implementation of trauma registries based on the Utstein style recommendations could facilitate system evaluation and comparison, but definitions and categorizations should be further developed. Efforts should be made to reduce the number of core data.

The American Brachytherapy Society recommendations for high-dose-rate brachytherapy for carcinoma of the endometrium.

PURPOSE: To develop recommendations for use of high-dose-rate (HDR) brachytherapy in patients with endometrial cancer. METHODS: A panel of members of the American Brachytherapy Society (ABS) performed a literature review, supplemented their clinical experience, and formulated recommendations for endometrial HDR brachytherapy. RESULTS: The ABS endorses the National Comprehensive Cancer Network (NCCN) guidelines for indications for radiation therapy for patients with endometrial cancer and the guidelines on HDR quality assurance of the American Association on Physicists in Medicine (AAPM). The ABS made specific recommendations for HDR applicator selection, insertion techniques, target volume definition, dose fractionation, and specifications for postoperative adjuvant vaginal cuff therapy, for vaginal recurrences, and for medically inoperable primary endometrial cancer patients. The ABS recommends that applicator selection should be based on patient and target volume geometry. The dose prescription point should be clearly specified. The treatment plan should be optimized to conform to the target volume whenever possible while recognizing the limitations of computer optimization. Suggested doses were tabulated for treatment with HDR alone, and in combination with external beam radiation therapy (EBRT), when applicable. For intravaginal brachytherapy, the largest diameter applicator should be selected to ensure close mucosal apposition. Doses should be reported both at the vaginal surface and at 0.5-cm depth irrespective of the dose prescription point. For vaginal recurrences, intracavitary brachytherapy should be restricted to patients with nonbulky (< 0.5-cm thick) disease. Patients with bulky (> 0.5-cm thick) recurrences should be treated with interstitial techniques. For medically inoperable patients, an appropriate applicator that will allow adequate irradiation of the entire uterus should be selected. CONCLUSION: Recommendations are made for HDR brachytherapy for endometrial cancer. Practitioners and cooperative groups are encouraged to use these recommendations to formulate their treatment and dose reporting policies. This will lead to meaningful comparisons of reports from different institutions and lead to advances and appropriate use of HDR.

American Brachytherapy Society recommendations for reporting morbidity after prostate brachytherapy.

PURPOSE: To standardize the reporting of brachytherapy-related prostate morbidity to guide ongoing clinical practice and future investigations. METHODS: Members of the American Brachytherapy Society (ABS) with expertise in prostate brachytherapy performed a literature review and, guided by their clinical experience, formulated specific recommendations for reporting on morbidity related to prostate brachytherapy. RESULTS: The ABS recommends using validated, patient-administered health-related quality-of-life instruments for the determination of baseline and follow-up data regarding bowel, urinary, and sexual function. Both actuarial and crude incidences should be reported, along with the temporal resolution of specific complications, and correlated with the doses to the normal tissues. The International Prostate Symptom Score is recommended to assess urinary morbidity, and any dysuria, gross hematuria, urinary retention, incontinence, or medication use should be quantified. Likewise, the "Sexual Health Inventory for Men," which includes the specific erectile questions of the International Index of Erectile Function, is the preferred instrument for reporting sexual function, and the loss of sexual desire, incidence of hematospermia, painful orgasm (orgasmalgia), altered orgasm intensity, decreased ejaculatory volume, use of erectile aids, and use of hormones for androgen deprivation should be quantified. The ABS recommends adoption of the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer acute and late radiation morbidity scoring scheme for reporting rectal morbidity and noting the incidence of rectal steroid, laser, or antidiarrheal use. CONCLUSION: It is important to focus on health-related quality-of-life issues in the treatment of prostate cancer, because the control rates are very similar between appropriate treatment modalities. The ABS recommends using the International Prostate Symptom Score, International Index of Erectile Function, and Radiation Therapy Oncology Group toxicity grading criteria for the determination of urinary, sexual, and bowel function, respectively. Additional parameters for reporting urinary, rectal, and sexual morbidities are presented. These morbidities should be correlated with the doses to the normal tissues. Some of these specific recommendations may be modified if and when new data become available.

Review of eye plaque dosimetry based on AAPM Task Group 43 recommendations. American Association of Physicists in Medicine.

PURPOSE: AAPM Task Group 43 recently revised the dosimetry recommendations for 125I seeds. We reviewed these guidelines and studied the effects of the recommendations on the prescription absorbed dose for patients who have undergone eye plaque therapy in our clinic. METHODS AND MATERIALS: 95 consecutive patients were chosen for this study. Absorbed doses at various points of clinical interest were computed based on conventional dose calculation algorithm (3, 4, 7) and TG-43 recommendations. For three representative plaques chosen, the seeds are approximated by isotropic point and line sources, respectively, and absorbed doses were calculated at all points on the central axis of the plaque. RESULTS: For apical heights shorter than 5 mm, treatment plans using model 6711 seeds delivered 10-13% lower absorbed doses than that calculated previously. For lesions with apical heights 5 mm or larger, the absorbed dose was 6-12% lower than prescribed. Calculations for model 6702 seeds indicated that TG-43 recommendations would produce 0-6% lower absorbed doses. Point doses calculated along the central axis of the plaque and isodose distributions at various levels showed that point source approximation of the seeds was clinically acceptable. CONCLUSIONS: TG-43 recommendations, if implemented, would result in lower absorbed doses unless the dose prescription is modified. The clinicians need to be aware of the dosimetric implications of these recommendations. The seeds may be approximated by isotropic point sources.
