Sensitive time-resolved fluoroimmunoassay for the detection of hazelnut (Corylus avellana) protein traces in food matrices.

Allergy to hazelnut is one of the most prevalent causes of severe food-allergic reactions in Norway, as recorded by The Norwegian National Reporting System and Register of Severe Allergic Reactions to Food. In the majority of the reported cases, there is "hidden", unlabelled hazelnut protein in processed foods like chocolate, cookies and cereal mixtures the eliciting agent. For a food survey study performed to evaluate the labelling practices with regards to hazelnut on behalf of the Norwegian Food Safety Authority, a new sensitive time-resolved fluoroimmunoassay (TR-FIA) for the detection of hazelnut protein traces in food matrices was developed and validated. The unique fluorometric properties of the europium-chelates used improved the signal-to-noise ratio because of low matrix interference and led to an enhanced sensitivity. The limit of detection was 0.1 mg/kg and the limit of quantitation was 0.33 mg/kg hazelnut protein. The recovery ranged from 73% to 123% in cookies and cereals, and from 50 to 77% in chocolate. The intra-assay precision was 7% and the inter-assay precision was 19%. Of 100 randomly chosen retail food products in Norway labelled "may contain hazelnut", 36 contained <0.2 mg/kg and seven >10 mg/kg hazelnut protein, demonstrating how differently this precautionary label is used.

Effect of dislodging techniques on foliar residue determination for agricultural crops.

The Agricultural Reentry Task Force (ARTF) conducted a study to determine whether different dislodgeable foliar residue (DFR) techniques had any effect on the amount of residues dislodged from the leaves of vegetable crops. Four previously employed techniques were evaluated with two chemicals (carbaryl and methomyl) on two crops (cabbage and lettuce). Carbaryl, a moderately water-soluble chemical, was applied at a rate of 2.0 lbs active ingredient/acre (lb ai/A) while methomyl, a highly water soluble chemical, was applied at a rate of 0.9 lb ai/A. One day after application, leaf punches were collected and the residues were dislodged following one of four techniques that differed in the number of dislodgings per sample, the duration of dislodging, the solution volume, and/or the type of solution used. The results indicated that three of the techniques gave similar results, whereas a fourth gave marginally lower results.

An innovative rapid response radiotherapy program to reduce waiting time for palliative radiotherapy.

BACKGROUND: Waiting for radiation therapy (RT) in Ontario has been a major problem for the past decade. In 1996, the Toronto-Sunnybrook Regional Cancer Centre (TSRCC) initiated a Rapid Response Radiotherapy Program (RRRP) to provide timely palliative RT for symptom relief of patients with terminal cancer. PURPOSE: This study reviews the clinical activity of the RRRP over the past 8 years to evaluate if we are meeting the objectives of the program. MATERIALS AND METHODS: From the TSRCC oncology patient information system (OPIS) database, we retrieved the number of patients referred to the RRRP, their demographics, diagnosis and treatment for the calendar years 1996 to 2003 inclusive. We calculated the time interval between referral to consultation, consultation to simulation and the percentage of cases who started RT on their initial consultation for all new cases referred to the RRRP. RESULTS: From 1996 to 2003, the number of cases seen in consultation increased from just over 200 cases annually in the first 2 years to about 500 cases per year in the last 4 years, for a total of 3,290. There were 1,792 (54%) men and 1,498 (46%) women; median age was 69 years (range, 21-95 years). Breast, lung, genitourinary and gastrointestinal primaries accounted for over 80% of all referrals. The majority was referred for palliative treatment of symptomatic bone (70%) or brain (14%) metastases. The dose fractionation for bone metastases was a single 8-Gy fraction in 45%, 20 Gy in five fractions in 42%, 30 Gy in ten fractions in 4% and other dose fractionations in 9%. Nearly 90% were seen within 2 weeks of referral (38% within 1 week). Eighty-five percent were simulated on the day of their initial consultation. Sixty percent started their RT treatment on the day of their consultation visit. The overall median interval from referral to treatment was 8 days. CONCLUSION: Over the past 8 years, the annual number of new cases referred to the RRRP has doubled. The overall median interval from referral to consultation was 8 days. Sixty percent were simulated, planned and started treatment on the day of their initial consultation. We therefore are meeting our goal of providing rapid access to palliative RT for symptomatic cancer patients.

Infertility rates following POMB/ACE chemotherapy for male and female germ cell tumours - a retrospective long-term follow-up study.

The risk of chemotherapy-induced infertility in male and female germ cell tumour (GCT) survivors is unclear, but may correlate with cisplatin dose. Here, we examine a large series of GCT patients for the effect of chemotherapy on those attempting to have children. Our GCT database was screened for nonseminomatous GCT patients who had (1). received POMB/ACE chemotherapy (cisplatin, vincristine, methotrexate, bleomycin alternating with actinomycin D, cyclophosphamide and etoposide) and (2). stage I male GCT patients who were untreated between 1977 and 1996. Fertility was assessed by questionnaire and medical records. A total of 64 of 153 treated and 35 of 115 untreated men attempted to have children. In all, 28% (18 out of 64) receiving POMB/ACE were unsuccessful. Radiotherapy (six), atrophic remaining testis (one) or prior infertility (three) were implicated in 10 cases, so chemotherapy-induced infertility may have occurred in only 11% (eight out of 64). Strikingly, 26% (nine out of 35) of untreated stage I patients also failed to have children (three had radiotherapy, three prior infertility). Moreover, in treated men, no association was seen between cisplatin dose and infertility. In contrast, radiotherapy significantly increased male infertility (P=0.001). Of 28 treated women who attempted to have children, 25% (seven out of 28) were unsuccessful. One previously had infertility and one subsequently had successful IVF so chemotherapy-induced infertility potentially occurred in only 18% (five out of 28) and was not related to cisplatin dose. In conclusion, the risk of chemotherapy-induced infertility is low in both male and female GCT patients and does not clearly correlate with the cumulative cisplatin dose.

Low-risk persistent gestational trophoblastic disease: outcome after initial treatment with low-dose methotrexate and folinic acid from 1992 to 2000.

PURPOSE: We have simplified the treatment of gestational trophoblastic disease (GTD) in order to reduce the number of patients exposed to potentially carcinogenic chemotherapy. Patients who score 0 to 8 on the Charing Cross scoring system are classified as low-risk and receive methotrexate (MTX) and folinic acid (FA), whereas those who score higher than 8 are classified as high-risk and receive the etoposide, methotrexate, and dactinomycin (EMA)/cyclophosphamide and vincristine (CO) regimen. PATIENTS AND METHODS: Between 1992 and 2000, 485 women with GTD were commenced on MTX/FA at Charing Cross Hospital, London, United Kingdom. If patients developed MTX resistance or toxicity, treatment was altered according to the level of beta human chorionic gonadotropin (hCG). If serum hCG was < or = 100 IU/L, patients received dactinomycin; if hCG was greater than 100 IU/L, patients received EMA/CO. RESULTS: The median duration of follow-up was 4.7 years. Overall survival was 100% and the relapse rate was 3.3% (16 of 485 patients). hCG values normalized in 324 (66.8%) of 485 patients with MTX alone, whereas 161 (33.2%) of 485 patients required a change in treatment, 11 because of MTX toxicity and 150 because of MTX resistance. Sixty-seven patients changed to dactinomycin, of whom 58 achieved normal hCG values, and nine required third-line chemotherapy with EMA/CO. hCG values normalized in 93 (98.9%) of 94 patients who changed directly to EMA/CO from MTX. CONCLUSION: Single-agent dactinomycin has activity in patients with low-risk GTD who develop MTX resistance and whose hCG is low. Simplifying the stratification of GTD into two classes (low- and high-risk) does not compromise overall outcome and may reduce the risk of second tumors.

Reanalysis with optimized power of red blood cell acetylcholinesterase activity from a 1-year dietary treatment of dogs to chlorpyrifos.

A no-observed-effect level (NOEL) of 0.1 mg/kg/day was reported for inhibition of red blood cell (RBC) acetylcholinesterase (AChE) in two groups of Beagle dogs fed chlorpyrifos (0, 0.01, 0.03, 0.1, 1 or 3 mg/kg/day) in the diet for 1 or 2 years (McCollister et al., Food Cosmet. Toxicol. 12 (1974) 45-61). The statistical analyses were by t-test that had low statistical power due to small sample sizes. Common time points for blood samples in both phases allowed a reanalysis of the grouped data over a 1-year time period. The reanalysis increased statistical power by increasing the sample size to n=14 from n=3 or 4, and decreasing the variance, by statistical step-by-step aggregation of the data from both phases, both sexes, and four sample periods. Factors retained in the ANOVA were dose, sex, and phase (sex-by-dose was not significant). Contrasts with one-sided t-tests indicated the 1 and 3 mg/kg/day groups had significantly inhibited RBC AChE (P<0.0001). At alpha=0.05, the uncorrected one-sided model had 80% power to detect a 12% decrease, 93% power for a 15% decrease, and 99.5% power for a 20% decrease in AChE activity. Overall, the reanalysis had high power to detect a clinically significant decrease in RBC AChE activity, and substantiated the original NOEL for chronic treatment of dogs to dietary chlorpyrifos at 0.1 mg/kg/day.

Prospective patient-based assessment of effectiveness of palliative radiotherapy for bone metastases.

PURPOSE: The primary objective of this report is to prospectively evaluate pain control provided by palliative radiotherapy for all irradiated patients with bone metastases by using their own assessments. MATERIALS AND METHODS: A prospective database was set up for all patients referred for palliative radiotherapy for bone metastases. Patients were asked to rate their pain intensity using an 11 categorical point scale (0=lack of pain, 10=worst pain imaginable). Analgesic consumption during the preceding 24 h was recorded and converted into equivalent total daily dose of oral morphine. For those who received radiotherapy, follow-up was conducted via telephone interviews at week 1, 2, 4, 8 and 12 post treatment using the same pain scale and analgesic diary. Radiotherapy outcome was initially assessed by pain score alone. Complete response (CR) was defined as a pain score of 0. Partial response (PR) was defined as a reduction of score > or =2 or a> or =50% reduction of the pre-treatment pain score. We further analyzed outcomes using integrated pain and analgesic scores. Response was defined as either a reduction of pain score > or =2 with at least no increase in analgesics or at least stable pain score with a > or =50% reduction in analgesic intake. RESULTS: One hundred and five patients were treated with palliative radiotherapy. When response evaluation was by pain score alone, the PR rates at 2, 4, 8 and 12 weeks were 44, 42, 30 and 38%, respectively; while the CR rates were 24, 32, 31 and 29%, respectively. The overall response rate at 12 weeks was 67%. When assessed by the integrated pain and analgesic scores, the response rates were 50, 46, 43 and 43%, respectively. CONCLUSION: The response rate in our patient population is comparable with those reported in clinical trials. This is important when counselling our patients on the expected effectiveness of radiotherapy outside of clinical trials. Our observations confirm the generalizability of the trials conducted to date. While randomized trials still remain the gold standard of research, observational studies can serve as useful adjuncts to randomized trials to confirm the efficacy and guide the design of new controlled trials.

Prospective assessment of symptom palliation for patients attending a rapid response radiotherapy program. feasibility of telephone follow-up.

Clinical trials generally include motivated patients with relatively good performance status. This can result in an overestimation of the effectiveness of an intervention. Clinic follow-up protocols for outcome assessment after palliative treatments suffer from high attrition rates. In this study, the feasibility of telephone follow-up for the assessment of symptom palliation in patients receiving outpatient palliative radiotherapy as a tool to evaluate outcome was examined. Patients referred for palliative radiotherapy were asked to rate their symptom distress using the modified Edmonton Symptom Assessment System (ESAS) at initial consultation. Patient demographics and analgesic consumption were collected. For those who received radiotherapy, follow-up was conducted through telephone interviews at week 1, 2, 4, 8, and 12 post-treatment using the same modified ESAS and analgesic diary. One hundred ninety patients received radiotherapy to 256 sites from January to August 1999. Seventy-eight patients (41%) died during the 12-week follow-up period. The percentage of surviving patients responding to the telephone interview ranged from 63% to 68% during the 12-week study. Telephone follow-up is a feasible tool for the prospective outcome assessment of symptom palliation in this population. It compares well to clinic visits or mailed questionnaires. However, to improve the follow-up rates, other modalities may also need to be implemented.

Surveillance for stage I testicular germ cell tumours: results and cost benefit analysis of management options.

Between 1979 and 1996 303 men with stage I testicular germ cell tumours (120 seminoma and 183 non-seminomatous germ cell tumours (NSGCT)) were enrolled onto a programme of surveillance. In our institutions the frequency of computed tomography (CT) scans is reduced compared with other centres. For all 303 men, the median follow-up is 5.1 years (range: 0.1-21.7 years) and there have only been 3 deaths (1 from disease, 1 from neutropenic sepsis and 1 from secondary leukaemia). 52/183 (28%) patients with NSGCT and 18/120 (15%) patients with seminoma have relapsed. The relapse-free survival at 5 years is 82% for seminoma and 69% for NSGCT (Logrank P=0.004). All men who relapsed, except 1 man with NSGCT, were in the International Germ Cell Cancer Collaborative Group good or intermediate prognosis group at relapse. Half of the seminoma relapses presented with symptoms and 31% of the NSGCT relapses. The remaining relapses were detected serologically or radiologically by the surveillance programme. 5 men (2%) on surveillance, 3 with initial diagnosis of seminoma and 2 with NSGCT, have developed second contralateral testis tumours (all stage I seminomas). In a well motivated centre a policy of surveillance for stage I testicular germ cell tumours (both NSGCT and seminoma) is associated with a low mortality rate (3/303, 1%) and may have the advantage of sparing overtreatment with potentially toxic therapies in this group of young men.

The coordinated psychosocial and neurologic care of children with seizures and their families.

SUMMARY: As the medical and surgical management of epilepsy continues to advance, issues associated with the quality of life of patients and their families can be addressed. Whenever associated with other handicaps, such as learning disabilities, attentional or behavioral disorders, and problems in psychological adjustment, dual-diagnosis issues must be identified. To provide comprehensive care for children with epilepsy, a team approach to psychosocial assessment and treatment must be provided and coordinated with neurologic care. When the age-related needs in the life stage of the individual and family are identified, the best possible adaptation of the patient and his or her family can be supported.

Etoposide and cisplatin/etoposide, methotrexate, and actinomycin D (EMA) chemotherapy for patients with high-risk gestational trophoblastic tumors refractory to EMA/cyclophosphamide and vincristine chemotherapy and patients presenting with metastatic placental site trophoblastic tumors.

PURPOSE: To evaluate the results of etoposide, cisplatin/etoposide, methotrexate, and actinomycin D (EP/EMA) chemotherapy in patients with gestational trophoblastic tumors (GTTs), who have relapsed after or who have become refractory to EMA/cyclophosphamide and vincristine (CO) chemotherapy, and in patients presenting with metastatic placental site trophoblastic tumors (PSTTs). PATIENTS AND METHODS: We have treated a total of 34 patients with GTT and eight patients with metastatic PSTT with the EP/EMA chemotherapy schedule. RESULTS: Twenty-two patients received EP/EMA because of apparent drug resistance to EMA/CO, and because the human chorionic gonadotropin (hCG) was near normal, they were not assessable for response. Twenty-one of these patients (95%) are alive and in remission. In the group where the hCG was high enough to confirm a response (greater than one log fall in hCG) to EP/EMA, all 12 patients responded and nine of these patients (75%) are alive and in remission. We have treated three patients with PSTT where the interval from antecedent pregnancy was less than 2 years, and all patients (100%) are alive and in remission. We have treated five patients where the interval from antecedent pregnancy was greater than 2 years and one fifth (20%) remain in remission. The survival for patients with GTT is 30 (88%) out of 34 patients and four (50%) out of eight patients for PSTT, giving an overall survival for these two cohorts of 34 (81%) out of 42 patients. The toxicity of this schedule is significant, with grade 3 or 4 toxicity (National Cancer Institute common toxicity criteria) recorded in hemoglobin (21%), WBC (68%), and platelets (40%). The role of surgery in this group of patients is important and contributed to sustained remission in five patients (23%) and possibly helped an additional seven patients (32%). CONCLUSION: EP/EMA is an effective but moderately toxic regimen for patients with high-risk GTT who become refractory to or relapse from EMA/CO chemotherapy. Also, EP/EMA clearly has activity in patients with metastatic PSTT.

Chemotherapy for gestational trophoblastic tumours hastens menopause by 3 years.

Chemotherapy may induce acute ovarian failure, but in women who retain gonadal function throughout chemotherapy, the late effects upon ovarian function are unknown. A retrospective controlled survey was performed to ascertain whether chemotherapy for gestational trophoblastic tumours (GTT) results in premature menopause. Questionnaires were sent to 1,489 women diagnosed between 1971 and 1990 with GTT, including 1089 who had received chemotherapy and 400 who had not received chemotherapy (controls). Responses were obtained from 972 chemotherapy-treated patients and 327 controls. 124 women were not evaluable for menopause date as they had undergone hysterectomy as part of the treatment for GTT or had developed permanent amenorrhoea during chemotherapy. Overall, 172 women reported that they were postmenopausal, including 157 women who had received chemotherapy. The median age at menopause for the evaluable population was 50 years (range 25-56 years). The age at menopause was significantly earlier in the treated arm (median 50, range 25-56 years) than in the controls (median 53, range 40-57 years) (logrank test chi 2 = 12.6, P = 0.0004). Menopause occurred significantly earlier in women treated with combination chemotherapy (median 49, range 25-56 years) compared with single agent methotrexate (median 51, range 25-56 years) (logrank test chi 2 = 8.3, P = 0.004). However, the age at completion of chemotherapy in the treated arm did not influence the age of menopause (proportional Hazards chi 2 = 1.99, P = 0.16). Chemotherapy for GTT induces menopause 3 years earlier than it occurs in women with GTT who do not receive chemotherapy. Although the difference is statistically significant, the magnitude is modest and most women can be reassured that neither fertility nor postmenopausal osteoporosis will be greatly affected.

Cancer among farmers: a meta-analysis.

PURPOSE: We conducted a meta-analysis of 37 studies to assess whether farmers had elevated rates for several cancers, as was concluded in a previous meta-analysis of 21 studies. METHODS: We identified studies from the reference list of the previous meta-analysis and from a MEDLINE search through December 31, 1994. The primary purpose of our analysis was to identify and, if possible, understand the sources of heterogeneity in the literature. Stratified analyses of studies and linear modeling with inverse variance weights were used to assess the impact of study characteristics on results. We calculated summary relative risks as a weighted average of the log relative risks across studies using inverse variance weights. Fixed and random effects models were used as appropriate. RESULTS: The results for most cancers were markedly heterogeneous by study design and, for fewer cancers, by geographic location, and whether the studies focused on crop and livestock farmers. There was some indication of publication bias due to underreporting of near null or sub null findings. Lip cancer was the only cancer that was clearly elevated among farmers. CONCLUSIONS: The results do not suggest that farmers have elevated rates of several cancers. However, the known heterogeneity of exposures by type of farming, geographic area, time period, and other factors limits the informativeness of meta-analyses of these studies for assessing potential carcinogenic exposures in agriculture.

Influence of chemotherapy for gestational trophoblastic disease on subsequent pregnancy outcome.

The aim of this study was to determine the influence of cytotoxic chemotherapy on subsequent reproductive performance. Details of post-treatment reproductive intent and outcome were requested from 1211 survivors registered at The Charing Cross Hospital gestational trophoblastic disease centre; a response rate of 96% was achieved. Seven hundred and twenty-eight women had tried to become pregnant; 607 reported at least one live birth, 73 conceived but had not registered a live birth, and 48 did not conceive. No differences were apparent between the 392 women who received methotrexate as single agent chemotherapy and the 336 treated with multi-agent chemotherapy. Women who had registered a live birth were younger (P < 0.0001) and the duration of follow up was significantly less among those who did not achieve pregnancy at all (P < 0.0003). A higher than expected rate of caesarean section and stillbirth was recorded. The chemotherapy protocols used by this unit have minimal impact on the subsequent ability to reproduce.

Management of resistant gestational trophoblastic tumors.

OBJECTIVE: To analyze the causes of therapeutic success and failure in the management of patients with high-risk gestational trophoblastic tumors (GTTs). STUDY DESIGN: Analysis of 272 consecutive high-risk patients treated at the trophoblastic disease center at the Charing Cross Hospital between 1979 and 1995. RESULTS: EMA (etoposide, methotrexate, actinomycin D)/CO (cyclophosphamide, vincristine) chemotherapy is our treatment of choice for patients with high-risk GTT. In 272 consecutive patients the cumulative five-year survival was 86.2% (95% confidence interval, 81.9-90.5%). No deaths occurred from GTT more than two years after the start of treatment. In patients whose disease became resistant to EMA/CO or relapsed after receiving EMA/CO, the majority (70%) could be salvaged with further chemotherapy (usually with the EP (etoposide, cisplatin)/EMA chemotherapy with or without surgery. Multivariate analysis identified the following adverse prognostic factors: presence of liver metastases (P < .0001), prolonged interval from antecedent pregnancy (P < .0001), presence of brain metastases (P = .0008) and term delivery of antecedent pregnancy (P = .045). Intensive chemotherapy for treating high-risk GTT carries a small risk of inducing second malignancies, and two patients developed acute myeloid leukemia, 2 cervical malignancy and 1 gastric adenocarcinoma after receiving EMA/CO chemotherapy. CONCLUSION: EMA/CO is an effective and well-tolerated regimen for high-risk GTT. Salvage chemotherapy with EP/EMA is effective in the majority of patients whose disease is resistant to EMA/CO and should be combined with surgery when the dominant site of resistant disease is known. Major adverse prognostic variables have been identified, and patients with combinations of these factors should be considered for innovative therapeutic approaches from the outset.

The management of high-risk gestational trophoblastic tumours (GTT).

Between 1979 and 1995 we have treated 272 consecutive women with high-risk (GTT including 121 previously treated patients who were treated with the weekly EMA/CO (etoposide, methotrexate, actinomycin D alternating with cyclophosphamide and vincristine). The median follow-up is 4.5 years (range 1-16 years). The cumulative 5 year survival is 86.2% (95% confidence interval 81.9-90.5%). No deaths from GTT occurred later than 2 years after starting EMA/CO. In a multivariate analysis, adverse prognostic factors were the presence of liver metastases (p < 0.0001), interval from antecedent pregnancy > 24 months (p < 0.0001), brain metastases (p=0.0008) and term delivery of antecedent pregnancy (p=0.045). There were 11 (4%) early deaths while 213 (78%) achieved complete remission. 47 (17%) developed drug resistance to EMA/CO of whom 33 (70%) were salvaged by further cisplatinum based chemotherapy and surgery. 2 women developed acute myeloid leukaemia after treatment with EMA/CO. 56% of women who have been in remission for at least 2 years and had fertility conserving surgery have achieved pregnancy since completing EMA/CO and there have been 112 live births including 3 babies with congenital abnormalities. EMA/CO is an effective, easy to administer and well tolerated regimen for treating patient with high-risk GTT. More than half of these women will retain their fertility. However, there is a small but significant increase in second malignancies.

POMB/ACE chemotherapy for mediastinal germ cell tumours.

Mediastinal germ cell tumours (MGCT) are rare and most published series reflect the experiences of individual institutions over many years. Since 1979, we have treated 16 men (12 non-seminomatous germ cell tumours and 4 seminomas) with newly diagnosed primary MGCT with POMB/ACE chemotherapy and elective surgical resection of residual masses. This approach yielded complete remissions in 15/16 (94%) patients. The median follow-up was 6.0 years and no relapses occurred more than 2 years after treatment. The 5 year overall survival in the non-seminomatous germ cell tumours (NSGCT) is 73% (95% confidence interval 43-90%). One patient with NSGCT developed drug-resistant disease and died without achieving remission and 2 patients died of relapsed disease. In addition, 4 patients with bulky and/or metastatic seminoma were treated with POMB/ACE. One died of treatment-related neutropenic sepsis in complete remission and one died of relapsed disease. Finally, 4 patients (2 NSGCT and 2 seminomas) referred at relapse were treated with POMB/ACE and one was successfully salvaged. The combination of POMB/ACE chemotherapy and surgery is effective management for MGCT producing high long-term survival rates.
