Efficacy of a killed vaccine for the control of paratuberculosis in Australian sheep flocks.

A field trial was undertaken from 1999 until 2004 to determine the efficacy of a killed M. a. paratuberculosis vaccine, Gudair, for the control of ovine Johne's disease (OJD) in merino sheep run under Australian pastoral conditions. On each of three farms experiencing significant OJD losses (5-15% per annum), 200 merino lambs (age 1-4 months) were vaccinated, and 200 lambs were left unvaccinated. Animal assessments and sample collections were conducted twice yearly until 4 or 5 years of age. The impact of vaccination on mortality rate, faecal shedding of M. a. paratuberculosis (by pooled and individual faecal culture), liveweight, wool productivity, vaccine injection site lesions and cellular (BOVIGAM) and humoral (PARACHEK) immunity was examined. Vaccination stimulated cell-mediated and humoral immune responses, reduced mortalities due to OJD by 90% and delayed faecal shedding for the first year post-vaccination. Thereafter, the prevalence of shedders among vaccinates was reduced by 90%. The numbers of M. a. paratuberculosis excreted by the vaccinated groups were also reduced by at least 90% at most sampling times. However, high levels of excretion by vaccinates occurred on some occasions, and although only 7 of 600 vaccinates died from OJD, all 7 had multibacillary lesions. Thus there remains a risk that some vaccinated sheep will transfer the disease. Small reductions in liveweight were found in vaccinated lambs in the first year, but there was little effect on wool production. Vaccine injection site lesions were detected in almost 50% of sheep after 2 months, and these persisted for at least 4 years in 20-25% of vaccinates. Data from this trial enabled the registration of Gudair in Australia in 2002 and underpins the pivotal role of vaccination in the current management of OJD.

Preliminary results of interstitial motexafin lutetium-mediated PDT for prostate cancer.

BACKGROUND AND OBJECTIVES: Interstitial photodynamic therapy (PDT) is an emerging modality for the treatment of solid organ disease. Our group at the University of Pennsylvania has performed extensive studies that demonstrate the feasibility of interstitial PDT for prostate cancer. Our preclinical and clinical experience is herein detailed. STUDY DESIGN/MATERIALS AND METHODS: We have treated 16 canines in preclinical studies, and 16 human subjects in a Phase I study, using motexafin lutetium-mediated PDT for recurrent prostate adenocarcinoma. Dosimetry of light fluence, drug level and oxygen distribution for these patients were performed. RESULTS: We demonstrate the safe and comprehensive treatment of the prostate using PDT. However, there is significant variability in the dose distribution and the subsequent tissue necrosis throughout the prostate. CONCLUSIONS: PDT is an attractive option for the treatment of prostate adenocarcinoma. However, the observed variation in PDT dose distribution translates into uncertain therapeutic reproducibility. Our future focus will be on the development of an integrated system that is able to both detect and compensate for dose variations in real-time, in order to deliver a consistent overall PDT dose distribution.

Internet use by patients with prostate cancer undergoing radiotherapy.

OBJECTIVES: To analyze the amount of Internet use, type of Internet use, and factors that predict Internet use by patients with prostate cancer. METHODS: A questionnaire evaluating the use of the Internet was given to 295 patients undergoing radiotherapy for prostate cancer in three different settings: an academic center (AC), a Veterans Affairs center (VA), and a community hospital. The study included 171 AC patients (58%), 104 VA patients (35%), and 20 community hospital patients (7%). RESULTS: The response rate to the questionnaire was greater than 99%. Overall, 128 (43%) of 295 patients had a home computer. This differed among the institutions, with 64% of AC patients and only 5% of VA patients having a home computer (P <0.0001). Overall, 94 (32%) of 295 patients used the Internet to access cancer information, with 48% of AC patients and 8% of VA patients using the Internet (P <0.0001). Seventeen percent of black patients (n = 113) had a home computer compared with 62% of white patients (n = 175; P <0.0001). Equal access to computers did not influence Internet use because, among those patients who had access to computers, black patients used the Internet less than did white patients (32% versus 61%, P <0.0001). Men 65 years of age or younger were more likely to use the Internet (45%) than those older than 65 years (28%; P = 0.004). Patients used many sites to access different types of information. CONCLUSIONS: A significant number of patients with prostate cancer access the Internet to obtain cancer information. Urologists and radiation oncologists should be familiar with this important resource to help patients access appropriate material.

Violence in a general hospital: comparison of assailant and other assault-related factors on accident and emergency and inpatient wards.

OBJECTIVE: This study sought to compare the characteristics of aggressive incidents occurring on inpatient (medical and surgical) wards with those occurring in the accident and emergency department in terms of assailant, employee and other factors. METHOD: A prospective interview-based survey design was adopted. Forty-eight assaulted staff were interviewed about 69 incidents within 7 days on average of the incident occurring. The presence or absence of various assailant, employee, situation, interaction and outcome factors derived from the UK Health Services Advisory Committee's model was compared between the two settings. RESULTS: Inpatient ward incidents were significantly more likely to have the following characteristics: female perpetrator, perpetrator aged over 70 years, daytime occurrence in a restricted area, resolved by support from other health care staff. CONCLUSION: Aggression frequently occurs on inpatient (medical and surgical) wards of a general hospital. Aggression management training for staff working in both accident and emergency and inpatient settings should be cognisant of the similarities and differences within general health care specialisms.

More than zero tolerance? Burnout and tolerance for patient aggression amongst mental health nurses in China and the UK.

OBJECTIVE: The aim of the study was to examine attitudes toward patient aggressive behaviour amongst mental health nurses in China and the UK and the relationship between these attitudes and burnout. The UK government policy of 'zero tolerance' of patient aggression may conflict with practitioner attitudes and could potentially increase the risk of aggression occurring. METHOD: Two surveys of mental health nurses were conducted, one in the People's Republic of China and one in the UK using the Perceptions of Aggression Scale (POAS). The UK sample also completed the Maslach Burnout Inventory (MBI). RESULTS: Some nurses in both groups agreed that patient aggression could sometimes have positive benefits. A sense of personal accomplishment at work (MBI) was significantly associated with a tendency to endorse positive statements about aggression. DISCUSSION: Nurses seem to have a complex set of attitudes toward this issue that do not simply equate with 'zero tolerance'.

ROC optimization may improve risk stratification of prostate cancer patients.

OBJECTIVES: Rational treatment decision requires accurate projection of the clinical course of a patient. Current methods in clinical outcome analysis mostly focus on population data. We investigated the applicability and optimization of the widely used actuarial method to project individual clinical outcomes. METHODS: We designed and implemented a Clinical Outcome Prediction Expert (COPE) that performs, assesses, and optimizes actuarial prediction on individual cases. We analyzed a post-prostatectomy database, consisting of 1043 patients. Sixty percent of the database was used for training and 40% for validation. Stratified actuarial curves are used to project individual outcomes. The prostate-specific antigen (PSA) level, the Gleason score, and the clinical American Joint Commission on Cancer Staging T-stage before treatment were used as predictors. The area under the receiver operator characteristic (ROC) curve was used to measure predictive performance. RESULTS: We obtained simple optimized stratification of pretreatment PSA level of 10 ng/mL or less, or more than 10 ng/mL; Gleason score of 6 or lower, or higher than 6; and clinical AJCC T-stage of T2a or lower, or higher. The optimized univariate risk scores were used to generate a multivariate score. After optimization, we found the higher risk group consisted of patients with PSA more than 10 ng/mL, or with PSA of 10 ng/mL or less and Gleason score higher than 6 and clinical AJCC T-stage higher than T2a. The optimized multivariate risk score has the highest ROC area of 0.77 among all predictors. CONCLUSIONS: The best conditions to perform actuarial prediction on individual cases are not known a priori and require optimization. This study shows that ROC optimization simplifies risk stratification and may improve the accuracy of clinical outcome prediction.

Estimating the impact on prostate cancer mortality of incorporating prostate-specific antigen testing into screening.

OBJECTIVES: Whether early detection using prostate-specific antigen (PSA) and digital rectal examination (DRE) compared with DRE alone will reduce prostate cancer mortality awaits the results of ongoing prospective randomized trials. However, the impact that early detection could have on prostate cancer-specific survival can be estimated by assuming that PSA failure after radical prostatectomy (RP) will translate into death from prostate cancer. METHODS: The study population consisted of 1274 men with clinically localized prostate cancer who underwent RP in Boston, Massachusetts or Philadelphia, Pennsylvania between 1989 and 2000 and had a preoperative PSA level greater than 4 but not more than 10 ng/mL. The primary endpoint was actuarial freedom from PSA failure (defined as PSA outcome). RESULTS: The relative risk of PSA failure after RP for patients diagnosed with a PSA of greater than 4 to 5, 5 to 6, 6 to 7, or 7 to 8 ng/mL compared with greater than 8 up to 10 ng/mL was 0.3 (95% confidence interval [CI] 0.2 to 0.5), 0.5 (95% CI 0.4 to 0.8), 0.6 (95% CI 0.4 to 0.9), or 0.9 (95% CI 0.6 to 1.3), respectively. On the basis of the estimates of the 5-year PSA outcome, patients with a biopsy Gleason score of 5 or 6 (781 of 1274; 61%) consistently benefited from RP performed when the PSA at diagnosis was greater than 4 to 7 ng/mL compared with greater than 8 to 10 ng/mL (93% versus 78%, P <0.0001). A benefit to early detection was not found for the vast majority (266 of 312; 88%) of patients who had a biopsy Gleason score of 7 or higher. CONCLUSIONS: Early detection using both PSA and DRE-based screening may benefit men who present with biopsy Gleason score 5 or 6 prostate cancer and a PSA level greater than 4 to 7 ng/mL compared with greater than 8 up to 10 ng/mL. This finding awaits validation from ongoing prospective randomized trials.

Using the receiver operating characteristic curve to select pretreatment and pathologic predictors for early and late postprostatectomy PSA failure.

OBJECTIVES: Pretreatment prostate-specific antigen (PSA), prostatectomy Gleason score, margin status, and pathologic T stage are known explanatory variables for the postprostatectomy PSA outcome. We used the receiver operating characteristic (ROC) curve to select those factors that were optimal for predicting early and late postoperative PSA failure. METHODS: We designed and implemented a clinical outcome prediction expert that performs, assesses, and optimizes the actuarial prediction on individual cases. A postprostatectomy database of 1022 patients was divided into 60% for training and 40% for validation. The ROC areas of the predictors were calculated over a range of cutoff time from 24 to 60 months. RESULTS: Multivariate pathologic T stage/prostatectomy Gleason score/margin status had the highest ROC area of 0.900. Patients with Stage T disease less than T3, negative surgical margins, and Gleason score of 6 or less had a 90% probability to be PSA failure free at 4 years versus 36% otherwise. The pathologic T stage/margin status accurately predicted PSA failure at 24 months or less after prostatectomy with an ROC area of 0.800. Lower risk patients (less than Stage T3, negative surgical margins) had a 94% probability to be PSA failure free at 2 years versus 46% otherwise. CONCLUSIONS: A combination of actuarial analysis and ROC optimization accurately identified the individual patients at high risk of early and late postprostatectomy PSA failure.

Predicting prostate specific antigen outcome preoperatively in the prostate specific antigen era.

PURPOSE: We evaluated the ability of previously defined risk groups to predict prostate specific antigen (PSA) outcome 10 years after radical prostatectomy in patients diagnosed with clinically localized prostate cancer during the PSA era. MATERIALS AND METHODS: Between 1989 and 2000, 2,127 men with clinically localized prostate cancer underwent radical prostatectomy, including 1,027 at Hospital of the University of Pennsylvania (study cohort) and 1,100 at Brigham and Women's Hospital (validation cohort). Cox regression analysis was done to calculate the relative risk of PSA failure with the 95% confidence interval (CI) in patients at intermediate and high versus low risk. The Kaplan-Meier actuarial method was used to estimate PSA outcome 10 years after radical prostatectomy. RESULTS: Compared with low risk patients (stages T1c to 2a disease, PSA 10 ng./ml. or less and Gleason score 6 or less) the relative risk of PSA failure in those at intermediate (stage T2b disease or PSA greater than 10 to 20 ng./ml. or less, or Gleason score 7) and high (stage T2c disease, or PSA greater than 20 ng./ml. or Gleason score 8 or greater) risk was 3.8 (95% CI 2.6 to 5.7) and 9.6 (95% CI 6.6 to 13.9) in the study cohort, and 3.3 (95% CI 2.3 to 4.8) and 6.3 (95% CI 4.3 to 9.4) in the validation cohort. The 10-year PSA failure-free survival rate in the 1,020 patients in the low, 693 in the intermediate and 414 in the high risk groups was 83%, 46% and 29%, respectively (p <0.0001). CONCLUSIONS: Based on 10-year actuarial estimates of PSA outcome after radical prostatectomy 3 groups of patients were identified using preoperative PSA, biopsy Gleason score and 1992 clinical T category.

Eastern Cooperative Oncology Group Phase I trial of protracted venous infusion fluorouracil plus weekly gemcitabine with concurrent radiation therapy in patients with locally advanced pancreas cancer: a regimen with unexpected early toxicity.

PURPOSE: We performed a phase I trial of protracted venous infusion (PVI) fluorouracil (5-FU) plus weekly gemcitabine with concurrent radiation therapy in patients with locally advanced pancreas cancer to determine the maximum-tolerated dose of gemcitabine that could be safely administered. We also sought to identify the toxicities associated with this treatment protocol. PATIENTS AND METHODS: Seven patients with locally advanced pancreas cancer were treated with planned doses of radiation (59.4 Gy) and PVI of 5-FU (200 mg/m(2)/d) with gemcitabine doses of 50 to 100 mg/m(2)/wk. RESULTS: Two of three patients at the 100-mg/m(2)/wk dose level experienced dose-limiting toxicity (DLT), as did three of four at the 50-mg/m(2)/wk dose level. One patient experienced a mucocutaneous reaction described as a Stevens-Johnson syndrome that was attributed to chemotherapy. Three patients developed gastric or duodenal ulcers with severe bleeding requiring transfusion. One patient developed severe thrombocytopenia lasting longer than 4 weeks. Three of the five episodes of DLT developed at radiation doses < or = 36 Gy. CONCLUSION: Based on this experience, we cannot recommend further investigation of regimens incorporating gemcitabine into regimens of radiation with PVI 5-FU. The mechanism of this synergistic toxicity remains to be determined.

Utilizing predictions of early prostate-specific antigen failure to optimize patient selection for adjuvant systemic therapy trials.

PURPOSE: Prostate-specific antigen (PSA) failure within 2 years after radical prostatectomy (RP) has been shown to be a clinically significant predictor of distant failure. This study was performed to estimate 2-year PSA failure rates on the basis of readily available clinical and pathologic factors to identify patients for whom effective adjuvant systemic therapy is needed. PATIENTS AND METHODS: A Cox regression multivariable analysis was used to determine whether the percentage of positive prostate biopsies, PSA level, and the pathologic findings at RP in 1,728 men provided clinically relevant information about PSA outcome after RP. A bootstrapping technique with 2,000 replications was used to provide 95% confidence intervals for the predicted 2-year PSA failure rates, which were determined on the basis of the independent clinical and pathologic predictors of PSA outcome. RESULTS: The independent predictors of time to PSA failure included a percentage of positive prostate biopsies of greater than 34% (P: < or =.009), PSA level greater than 10 ng/mL (P: < or =.01), seminal vesicle invasion (P: =. 02), prostatectomy Gleason score of 8 to 10 (P: =.04), and positive surgical margins (P: =.0001). Predictions of 2-year PSA failure rates and bootstrap estimates of the 95% confidence intervals were arranged in a tabular format, stratified by independent clinical and pathologic predictors of PSA outcome. CONCLUSION: Patients who are most likely to benefit from effective adjuvant systemic therapy after RP can be identified using readily available clinical and pathologic data.

Outcome of pancreaticoduodenectomy and impact of adjuvant therapy for ampullary carcinomas.

PURPOSE: To determine the clinical outcomes and potential impact of adjuvant chemoradiation in patients undergoing surgical resection of ampullary carcinoma. PATIENTS AND METHODS: Between 1988 and 1997, 39 patients underwent pancreaticoduodenectomy for ampullary adenocarcinomas. Clinical and pathologic factors, adjuvant therapy records, and disease status were obtained from chart review. Thirteen (33%) patients received adjuvant chemoradiation. Radiation therapy was delivered to the surgical bed and regional nodes to a median dose of 4,860 cGy with concurrent bolus or continuous infusion of 5-fluorouracil. Outcomes measures included locoregional control, disease-free survival, and overall survival. Univariate analysis was used to assess the impact of various patient- and tumor-related factors and the use of adjuvant therapy. Twenty (51%) patients with tumor invasion into the pancreas (T3) or node-positive disease were classified in a "high-risk" subgroup. RESULTS: After a median follow-up of 45 months for survivors, overall 3-year survival was 55%. Survival was significantly worse for patients with positive nodes (23% vs. 73%, p < 0.001) and high-risk status (30% vs. 80%, p = 0.002). Disease-free survival was 54% at 3 years. There were 3 postoperative deaths, and these patients (all high risk) are excluded from further analysis on adjuvant therapy. In univariate analysis, the use of adjuvant chemoradiation had no clear impact on local-regional control or overall survival. However, by controlling for risk status in multivariate analysis, the use of adjuvant therapy reached statistical significance for overall survival (p = 0. 03). Among the high-risk patients, 7 (77%) of 9 patients receiving adjuvant therapy remained disease-free during follow-up compared with only 1 (14%) of 7 patients not receiving adjuvant therapy (p = 0.012). CONCLUSION: Despite the relatively favorable prognosis of ampullary carcinomas compared with other pancreaticobiliary tumors, patients with nodal metastases or T3 disease are at high risk for disease relapse. The use of adjuvant chemoradiation may improve long-term disease control in these patients.

Prostate specific antigen outcome based on the extent of extracapsular extension and margin status in patients with seminal vesicle negative prostate carcinoma of Gleason score < or = 7.

BACKGROUND: Early (< or = 2 years) prostate specific antigen (PSA) failure after radical prostatectomy (RP) has been shown to predict for distant failure. After excluding patients with the pathologic predictors of early PSA failure, an analysis of PSA failure free (bNED) survival was performed to identify patients who may benefit from the use of postprostatectomy radiation therapy (RT). METHODS: Of 1,028 patients treated with RP for clinically localized prostate carcinoma between 1989 and 1999, 862 (84%) had either organ confined (OC), specimen confined (SC), or margin positive disease with negative seminal vesicles (SV) and a prostatectomy Gleason score < or = 7. A Cox regression multivariate analysis was performed in these patients evaluating the ability of the extent of extracapsular extension (ECE) (into but not through the capsule, SC focal ECE, SC established ECE, margin positive) and prostatectomy Gleason score (2-6 vs. 7) to predict time to postoperative PSA failure. RESULTS: SC focal ECE (P = 0.0017), SC established ECE (P < 0.0001), and margin positive disease (P < 0.0001) were significant predictors of time to postoperative PSA failure, whereas prostatectomy Gleason score and disease extending into but not through the capsule were not. Five-year bNED rates were 90%, 88%, 69%, 45%, and 33% for patients with OC, into but not through capsule, SC focal ECE, SC established ECE, and margin positive prostate carcinoma, respectively. CONCLUSIONS: Patients with SC ECE or margin positive prostate carcinoma and a prostatectomy Gleason score < or = 7 with no evidence of SV invasion may benefit from adjuvant postoperative RT.

Quality control and optimized procedure of hybridization capture-PCR for the identification of Mycobacterium avium subsp. paratuberculosis in faeces.

Nucleic acid sequence capture techniques are used to improve both the sensitivity and specificity of PCR for the diagnosis of plant, animal and human diseases. Hybridization capture-PCR (HC-PCR) was first reported as a method for the detection of Mycobacterium avium subsp. paratuberculosis in 1995 and was successfully trialed on a small number of faecal samples from cattle with Johne's disease. A locally optimized HC-PCR method was evaluated on faeces from infected and non-infected animals. However, sample to sample cross contamination during the DNA purification step highlighted that the original format of the test was unsuitable for routine diagnostic use. Here, we report modifications and optimization of HC-PCR, particularly with respect to DNA purification from faeces, hybridization and capture steps. We also identified procedurally sensitive critical points in the test during capture and washing of magnetic beads. Southern blotting was omitted from the protocol to preserve specificity but this resulted in analytical sensitivity of 5000 organisms per 200 mg faecal sample. Nevertheless, HC-PCR detected M.paratuberculosis in pellets from infected sheep diluted at rates of up to 1 in 100 in normal faeces, suggesting that the technique should be evaluated further for low-cost diagnosis in flocks/herds using pooled samples.

Combination of the preoperative PSA level, biopsy gleason score, percentage of positive biopsies, and MRI T-stage to predict early PSA failure in men with clinically localized prostate cancer.

OBJECTIVES: Early (2 years or less) prostate-specific antigen (PSA) failure has been shown to predict for distant failure. The independent clinical predictors of time to postoperative PSA failure were used to identify prostate cancer patients at high risk for early PSA failure. METHODS: A Cox regression multivariable analysis was used to determine whether additional predictive information was provided by the endorectal coil magnetic resonance imaging (erMRI) T-stage when controlling for the established prognostic factors in predicting the time to postoperative PSA failure in 977 men with palpable (T2) or PSA-detected (T1c) prostate cancer. RESULTS: Preoperative PSA (P = 0.0001), percentage of positive prostate biopsies (P= 0.0001), erMRI T-stage (P = 0.0001), biopsy Gleason score (P = 0.0015), and clinical stage T2c disease (P = 0.004) were independent predictors of time to postoperative PSA failure. Two-year PSA failure rates derived from the Cox regression model and bootstrap estimates of the 95% confidence intervals are presented in nomogram format stratified by the preoperative PSA, percentage of positive prostate biopsies, erMRI T-stage, and the biopsy Gleason score. CONCLUSIONS: Patients at high risk for early PSA failure and subsequent distant progression include men with erMRI T3 disease and 3 or more of 6 cores positive for a Gleason score 6 or higher disease when the PSA is more than 10 but not more than 20 ng/mL and any Gleason score when the PSA is more than 20 ng/mL. Men with erMRI T2 disease and 3 or more of 6 cores positive for a Gleason score 8 or higher disease and who have a PSA more than 20 ng/mL are also at high risk. Neoadjuvant therapy trials in these select patients may be justified.

Erectile function and quality of life after interstitial radiation therapy for prostate cancer.

Few studies have evaluated erectile function after interstitial radiation therapy for localized prostate cancer. Using a validated quality of life questionnaire, we assessed post-treatment erectile function and its relationship to treatment satisfaction and quality of life. We retrospectively reviewed the records of 171 consecutive patients who underwent Pd-103 or I-125 brachytherapy for prostate cancer between December 1992 and June 1998. Seventy percent of patients received neoadjuvant androgen deprivation therapy. All patients were mailed a validated questionnaire assessing sexual function and overall quality of life (UCLA Prostate Cancer Index and SF-36). Sixty-seven percent of all questionnaires were available for evaluation (114/171). The mean age was 69.1 y with a mean follow-up of 23 months (range 4-72, median 24). Seventy-one percent of patients (81/114) had pre-treatment erections sufficient for sustained vaginal penetration. Of these patients, potency was maintained in 49% of men (40/81). An additional 26% had erections firm enough for foreplay but not penetration (21/81). Erectile dysfunction rates were significantly lower in younger patients (48%) vs older patients (55%). There was no difference in post-treatment potency between men who received neoadjuvant hormonal therapy and those who did not (P>0.05). In addition, there were no differences in physical function (86, scale 0-100), general health perception (78), emotional well-being (83), energy/fatigue (74), and overall satisfaction (84) between men with erectile dysfunction and those without. In summary, two years following brachytherapy 25% of patients complained of complete (20/81) or partial (26%, 21/81) erectile dysfunction, for an overall rate of 51% (41/81). Short-term neoadjuvant hormonal therapy (<3-6 months) did not increase the likelihood of post-treatment erectile dysfunction. Interestingly, overall satisfaction rates among brachytherapy patients were high (84/100) and surprisingly did not correlate with post-treatment sexual function.
