Enbrel, Humira and Remicade are 3 very different agents varying in their route and frequency of administration but their effects and side-effect profile are very similar. The main side-effect is infection but the risk of that can be minimised by screening for infections including TB prior to administration. There are very small risks of aggravating demyelination so these drugs are not given to patients who have had previous episodes suggestive of multiple sclerosis. There is a risk of recurrent malignancy so these drugs are also not given to patients with a past history of malignancies such as breast or melanoma.

Genetic factors or the epileptic condition itself ; , may be more important than drug therapy in leading to birth defects. As we improve on the treatment and outcomes of women diagnosed with early-stage breast cancer, it is critical that we understand the impact of new treatments on long-term morbidity and quality of life. We are well aware of the toxicities and benefits associated with adjuvant tamoxifen therapy. In fact, the results of recent large adjuvant trials that compared aromatase inhibitors with tamoxifen in the adjuvant setting have begun to outline and refine data on these end points. Aromatase-inhibitor therapy clearly increases loss of bone mineral density, and this change apparently is pronounced to a greater degree in premenopausal women who undergo chemically induced menopause. Both the Arimidex, Tamoxifen, Alone or in Combination trial and the Breast International Group I-98 trial have demonstrated that aromatase inhibitor therapy in postmenopausal women increases the rate of fracture compared with tamoxifen use. Researchers involved in the Austrian Breast Cancer Study Group ABCSG ; -12 trial are evaluating the effect of ovarian suppression with goserelin Zoladex ; used with either tamoxifen or anastrozole Arimidex ; as adjuvant hormonal therapy for premenopausal breast cancer patients. Zoledronic acid Zometa ; was given every 6 months to half of the patients participating in the trial; the other patients did not receive a bisphosphonate over that period. This small substudy demonstrated that the use of zoledronic acid can abrogate completely the loss in bone mineral density resulting from chemical menopause induced in premenopausal women; this held true whether patients were given tamoxifen or anastrozole. Interestingly, anastrozole treatment was associated with a much more rapid and profound bone mineral density loss than was tamoxifen therapy--a finding similar to that of studies in postmenopausal women. Finally, no fractures were observed in this trial, and no serious toxicity was observed. Should all women on aromatase inhibitors receive a potent bisphosphonate? Given the lack of data suggesting that fractures may be avoided by prophylactic use of bisphosphonates, I would suggest that they should not. Instead, as oncologists, we must monitor patients for the side effects of agents that we prescribe. In this case, bone mineral density should be monitored and oral bisphosphonates should be instituted promptly for significant change. Patients who cannot tolerate or do not benefit sufficiently from currently prescribed oral agents reasonably could be offered zoledronic acid therapy every 6 months. Future data from two trials, the zoledronic acid letrozole Femara ; Adjuvant Synergy trial and the Cancer and Leukemia Group B 79809 trial, which are evaluating up-front treatment with zoledronic acid versus delayed therapy in women taking adjuvant aromatase inhibitors, will help us to understand the appropriate use of bisphosphonates in this setting. -- Hope S.

Tamoxifen questions and answersEndometrial cancer tamoxifenAlthough differences in race, culture, climate, and even in language, finding no suitable words for reporting hot flashes, may be possible explanations. Therefore, phytoestrogens have been thought to hold a promise as an alternative therapy for menopausal symptoms, and they have been widely used, even though scientific evidence of their efficacy is poor or totally lacking Kaufert et al. 1998, Davis 2001, Kam et al. 2002, Naftolin and Stanbury 2002 ; . Hence, we designed a randomized placebo-controlled study to evaluate the usefulness of phytoestrogens in the treatment of menopausal complaints and the effects of isoflavonoids on surrogate markers of bone and vascular health. Tamoxifen dosage instructionsWhere to get tamoxifen without prescriptionA. Published results from two RCTs were pooled in the Canadian systematic review.10 In one RCT NSABP B-17; n 814 ; radiotherapy following conserving surgery reduced the rate of ipsilateral invasive recurrence, at 8-years follow-up, from 13.4% to 3.9% P 0.0001 ; , and the rate of ipsilateral non-invasive recurrence from 13.4% to 8.2% P 0.007 ; .14 At 4-years follow-up the EORTC 10853 ; trial n 1010 ; showed a reduction in local invasive recurrence with radiotherapy from 8% to 4% HR 0.60, 95% CI 0.37 to 0.97 ; , and a reduction in local non-invasive recurrence with radiotherapy from 8% to 5% HR 0.65, 95% CI 0.41 to 1.03 ; .15 The pooled relative risk for local recurrence was 0.53 95% CI 0.37 to 0.75, P 0.0004; n 1824 ; in favour of conserving surgery plus radiotherapy Grade I ; . The EORTC trial reported a significantly higher rate of contralateral breast cancer with radiotherapy, whereas the NSABP trial reported a higher, but not statistically significant, difference in the same direction. The pooled relative risk for contralateral recurrence favoured patients who did not receive radiotherapy RR 1.88, 95% CI 1.12 to 3.16, P 0.017; n 1816 ; . Using the same two RCTs but shorter follow-up data available at that time ; , and 23 non-randomised studies n 1349 ; , the Australian review concluded in 1998 that conservative surgery with radiotherapy was associated with an intermediate level of local recurrence 8% ; from either DCIS 4.3% ; or invasive cancer 3.7% ; at an approximate follow-up of 4 years Grade III ; . The review reports that there is a lack of reliable evidence of any reduction in risk of distant relapse with radiotherapy. The UKCCCR DCIS working party has submitted for publication the findings from the UK, Australia and New Zealand RCT. As the data are unpublished they cannot be described here in detail. Women with completely excised DCIS were randomised to radiotherapy n 118 ; , taoxifen n 664 ; or tsmoxifen plus radiotherapy n 912 ; . Median follow up data at 52.6 months indicated that radiotherapy significantly reduced the incidence of ipsilateral invasive recurrence and ipsilateral DCIS, 12 D.

Tamoxifen for fertilityHealth education was an essential part of the daily programme and was divided into two categories: health and nutrition. Health education concerned the symptoms of diabetes, types of insulin, hypoglycaemia, foot care, and guidance on self-monitoring and injecting. Nutritional education included the role of different groups of food, sugar content, nutritional evaluation and calculation. Fig. 5. Scatchard analysis of 13Hltamoxifen binding to antioestrogen-binding sites of rat liver Rat liver 20000g supernatant 0.5 ml; protein concn. 0.7 mg ml ; was incubated for 16 h at with various concentrations of [3H]tamoxifen 0.25-5.0 nM ; in the absence V ; or presence El ; of 15 , uM- or A ; 30, uM-linoleic acid. Separation of bound from free ligand was performed by using dextran-coated charcoal as described in the Materials and methods section. Specifically bound [3H]tamoxifen is the difference between binding obtained in the absence and presence of excess unlabelled tamoxifen 1.25 SM and triphasil and tamoxifen. Results Meta-analysis showed no evidence that any one class of endocrine agent was superior to the others in terms of survival, based on 3 RCTs of initial treatment with tamoxifen versus MA n 309 ; , 2 RCTs of initial treatment with tamoxifen versus MPA n 311 ; , and 1 RCT of initial treatment with tamoxifen versus formestane n 409 ; . There were no RCTs of initial treatment with anastrozole or letrozole versus tamoxifen. None of these trials reported quality of life using validated instruments. 3 Attachment 4 amount-of-positive-nodes is NOT used.
