Abstract
PURPOSE Glucocorticoids (GCs) are commonly used in breast cancer patients to ameliorate emesis induced by chemotherapy. Some preclinical studies have suggested that systemic GCs might promote survival of estrogen receptor (ER)-negative breast cancer cells. This study aims to clarify their clinical effect on patient survival. METHODS A total of 18,596 women with newly diagnosed stage I-III breast cancer in 2002-2006 were identified from the Taiwan Cancer Database and drug treatment was examined from the Taiwan National Health Insurance Claims Database. Of these, 3989 who did not receive adjuvant chemotherapy (non-chemotherapy cohort) and 3237 patients who received six cycles of adjuvant anthracycline-based chemotherapy (anthracycline cohort) were included. The impact of GC use on survival was analyzed separately in these two cohorts using Cox proportional hazards models. RESULTS In the non-chemotherapy cohort, GC use was associated with aggressive clinicopathological features of breast cancer. High-dose GC was associated with shorter overall survival in univariate analysis but not in multivariate analysis. In the anthracycline cohort, multivariate analysis showed that GC use at each dose level was significantly associated with longer breast cancer-specific survival (HR 0.65, 0.70, and 0.70 for low-dose, median-dose, and high-dose GC, respectively) and overall survival (HR 0.72, 0.76, and 0.73, respectively) when compared with those receiving no GC. The associations were significant in both ER-positive and ER-negative subgroups for breast cancer-specific survival, and in ER-negative subgroup for overall survival. CONCLUSION Concomitant use of GC improved survival in patients receiving adjuvant anthracycline-based chemotherapy for stage I-III breast cancer.

Abstract
BACKGROUND Glucocorticoids are often used in the treatment of nonhematologic malignancy. This review summarizes the clinical evidence of the effect of glucocorticoid therapy on nonhematologic malignancy. METHODS A systematic review of clinical studies of glucocorticoid therapy in patients with nonhematologic malignancy was undertaken. Only studies having endpoints of tumor response or tumor control or survival were included. PubMed, EMBASE, the Cochrane Register/Databases, conference proceedings (ASCO, AACR, ASTRO/ASTR, ESMO, ECCO) and other resources were used. Data was extracted using a standard form. There was quality assessment of each study. There was a narrative synthesis of information, with presentation of results in tables. Where appropriate, meta-analyses were performed using data from published reports and a fixed effect model. RESULTS Fifty four randomized controlled trials (RCTs), one meta-analysis, four phase l/ll trials and four case series met the eligibility criteria. Clinical trials of glucocorticoid monotherapy in breast and prostate cancer showed modest response rates. In advanced breast cancer meta-analyses, the addition of glucocorticoids to either chemotherapy or other endocrine therapy resulted in increased response rate, but not increased survival. In GI cancer, there was one RCT each of glucocorticoids vs. supportive care and chemotherapy +/- glucocorticoids; glucocorticoid effect was neutral. The only RCT found of chemotherapy +/- glucocorticoids, in which the glucocorticoid arm did worse, was in lung cancer. In glucocorticoid monotherapy, meta-analysis found that continuous high dose glucocorticoids had a detrimental effect on survival. The only other evidence, for a detrimental effect of glucocorticoid monotherapy, was in one of the two trials in lung cancer. CONCLUSION Glucocorticoid monotherapy has some benefit in breast and prostate cancer. In advanced breast cancer, the addition of glucocorticoids to other therapy does not change the long term outcome. In GI cancer, glucocorticoids most likely have a neutral effect. High dose continuous glucocorticoids have a detrimental effect in nonhematologic malignancy. Glucocorticoid therapy might have a deleterious impact in lung cancer.

Abstract
CONTEXT The sodium iodide symporter (NIS) mediates the active iodide uptake in the thyroid gland as well as lactating breast tissue. Recently induction of functional NIS expression was reported in the estrogen receptor-positive human breast cancer cell line MCF-7 by all-trans retinoic acid (atRA) treatment in vitro and in vivo, which might offer the potential to treat breast cancer with radioiodine. OBJECTIVE In the current study, we examined the effect of dexamethasone (Dex) on atRA-induced NIS expression and therapeutic efficacy of 131-I in MCF-7 cells. DESIGN For this purpose, NIS mRNA and protein expression levels in MCF-7 cells were examined by Northern and Western blot analysis after incubation with Dex (10(-9) to 10(-7) m) in the presence of atRA (10(-6) m) as well as immunostaining using a mouse monoclonal human NIS-specific antibody. In addition, NIS functional activity was measured by iodide uptake and efflux assay, and in vitro cytotoxicity of 131-I was examined by in vitro clonogenic assay. RESULTS After incubation with Dex in the presence of atRA, NIS mRNA levels in MCF-7 cells were stimulated up to 11-fold in a concentration-dependent manner, whereas NIS protein levels increased up to 16-fold and iodide accumulation was stimulated up to 3- to 4-fold. Furthermore, iodide efflux was modestly decreased after stimulation with Dex in the presence of atRA. Furthermore, in the in vitro clonogenic assay, selective cytotoxicity of 131-I was significantly increased from approximately 17% in MCF-7 cells treated with atRA alone to 80% in MCF-7 cells treated with Dex in the presence of atRA. CONCLUSION Treatment with Dex in the presence of atRA significantly increases functional NIS expression levels in addition to inhibiting iodide efflux, resulting in an enhanced selective killing effect of 131-I in MCF-7 breast cancer cells.

Abstract
Purpose: Increasing numbers of older women are affected by early breast cancer, because of prolonged life expectancy and the increasing incidence of breast cancer with age. The role of adjuvant therapy for this population is still a matter of debate. We reviewed the long-term outcome of a mature trial comparing endocrine treatment versus no adjuvant therapy in older women with node-positive breast cancer. Patients and Methods: From 1978 to 1981, 349 women 66 to 80 years of age with pathologically involved lymph nodes after total mastectomy and axillary clearance were randomly assigned to receive 12 months of adjuvant tamoxifen plus low-dose prednisone (p+T) or no adjuvant therapy. Three hundred twenty patients were eligible. Results: At 21 years’ median follow-up, 1 year of p+T significantly prolonged disease-free survival (DFS; P = .003) and overall survival (P = .05; 15-year DFS, 10% ± 3% v 19% ± 3%; hazard ratio, 0.71; 95% CI, 0.58 to 0.86). When comparing competing causes of failure (breast cancer recurrence and deaths before breast cancer recurrence), p+T was far superior in controlling breast cancer recurrence (P = .0003), but the improvement was seen mainly in soft tissue sites. Conversely, patients in the p+T group were more likely to die before a breast cancer recurrence (P = .03). Conclusion: This trial demonstrates that significant treatment benefits continue to be observed in older patients treated for 1 year with p+T. Despite issues relating to competing causes of failure, older breast cancer patients can benefit from treatment and should be considered for trials of adjuvant systemic therapy.

Abstract
Endocrine treatment plays an important role in the therapy of breast cancer. While the basic mechanisms are understood, additional mechanisms may be of importance to their action and they may also contribute to the mechanism(s) of acquired resistance. Currently, several novel drugs are entering into clinical trials. Observations of the absence or presence of cross resistance to novel 'pure' steroidal antiestrogens and the non-steroidal tamoxifen may add important information to our understanding of the mechanisms of action of both classes of drugs. Similarly, exploration of different aromatase inhibitors in sequence or concert, as well as the combining of different endocrine treatment options may be warranted. Additionally, alterations in different biochemical parameters such as growth factors should not only be carefully explored in relation to treatment options but should also be followed during the course of treatment to asess alterations over time and in relation to the development of drug resistance.

Abstract
Drug resistance is the main reason for therapeutic failure and death in breast cancer. In vitro investigations have identified some mechanisms that may be responsible for resistance to chemotherapeutic agents in breast cancer, but we know little about the mechanisms responsible for resistance to endocrine treatment in receptor-positive tumors. Accordingly, a major task for future studies is to explore the mechanisms of both primary and acquired resistance to endocrine treatment as well as to chemotherapy in breast cancer. Drug resistance may be related to alterations in endocrine as well as paracrine delivery of certain growth factors or hormones, but it may also be caused by alterations in drug disposition. Primary resistance may be evaluated by comparing the response to drug treatment with the expression of different biochemical parameters in the tumor before treatment. To explore the mechanisms of acquired drug resistance requires study of the changes in biological parameters developing over time during drug therapy. Also, it may be of interest to use certain drugs (like a 'classical' anti-estrogen and a steroidal anti-estrogen) in a particular sequence to explore the possibility of cross-resistance (or lack of it) between particular treatment modalities. Possible implications for the design of future trials in breast cancer treatment are discussed.

Abstract
To assess the effect of danazol in advanced breast cancer 183 patients were randomised to receive either tamoxifen plus danazol or tamoxifen plus placebo. Patients underwent systemic work-up pretreatment then every 12 weeks or sooner if they clinically progressed. There were no differences in objective response rates with tamoxifen plus danazol vs. tamoxifen plus placebo (27% vs. 24%), time to progression (median 6.4 vs. 6.2 months) or survival (median 22.6 vs. 23.5 months) when the two arms were compared (all P > 0.5). The addition of danazol to tamoxifen had no effect on time to progression when adjusted for significant prognostic factors in a multivariate analysis. However, it was found incidentally that weight was stable on tamoxifen plus danazol (average gain 0.6 kg, S.E. 0.6 kg) compared with a significant loss on tamoxifen plus placebo (average loss 2.0 kg, S.E. 0.6 kg, P = 0.003). The average weight was maintained on tamoxifen plus danazol even in patients who did not respond to treatment.

Abstract
To determine the effect of prednisolone on severe hypercalcaemia in women with metastatic breast cancer, 30 patients with serum ionized calcium above 1.60 mmol l-1 (reference range 1.15-1.35 mmol l-1) entered a randomized trial. Performance status before entry to the trial and survival time after hypercalcaemia were also noted. All patients received 4 l of isotonic saline daily and 80 mg intravenous furosemide three times daily for 2 d; thereafter they received 3 l of isotonic saline daily and 80 mg furosemide twice daily for 6 d. Fifteen patients were randomized to receive prednisolone, 25 mg orally, three times daily for 8 d. Serum ionized calcium decreased significantly in both groups, but most markedly in the prednisolone group. The median difference was 0.28 mmol l-1 (95% confidence interval (CI), 0.09-0.52) on day 4 and 0.21 mmol l-1 (95% CI, 0.12-0.44) on day 8. In seven prednisolone-treated patients serum ionized calcium normalized, compared to none in the control group (Fisher's exact test; P = 0.028). No severe adverse effects were observed. Prior to detection of hypercalcaemia all patients were severely immobilized, primarily due to bone pain. Only 10 patients were still living after 3 months. Prednisolone, furosemide and rehydration is superior to furosemide and rehydration alone in severely hypercalcaemic patients with metastatic breast cancer in whom immobilization appears to be an early warning sign of life-threatening hypercalcaemia. The short survival time was not influenced by prednisolone.

Abstract
A very simple, low dose, orally administered regime (10 to 15 mg of fluoximesterone + 6 mg of deflazacort daily for periods of 1 to several months) resulting in mild-acceptable toxicity (essentially some weight gain) determined subjective improvement In 2/3 of 34 evaluable patients (out of 36 treated) and an objective measurable tumor reduction in 1/3, although most patients had been previously treated with chemotherapy and hormone treatment and proved primarily or secondarily refractory. The receptor status at the beginning of fluoximesterone + deflazacort treatment was not known, except in one negative-receptor patient, who responded to the combination after becoming resistant to tamoxifen (see photo). In some patients the condition of hormone refractoriness would suggest a no-treatment policy, but a trial with this regime is always convenient as it may improve both duration and quality of life.

Abstract
Glucocorticoids are often included with other agents in cancer treatment although the mode of action is not clear. They are useful in the primary combination chemotherapy of both acute and chronic lymphocytic leukaemias, Hodgkin's and non-Hodgkin's lymphomas, multiple myeloma and breast cancer. Other uses for glucocorticoids in cancer patients include an anti-inflammatory action for the oedema of cranial and spinal metastases, a weak antihypercalcaemic effect and the ability to suppress tumour-related fever.

Abstract
This trial was conducted to determine if the reported superiority of tamoxifen (TAM) plus prednisolone (PRDLN) over TAM alone in postmenopausal women with metastatic breast cancer could be corroborated. A total of 326 patients were randomized on a double-blind trial to TAM (10 mg twice daily) plus placebo or TAM plus PRDLN (5 mg twice daily). Six patients (2%) were disqualified. Considering 256 patients with measurable or evaluable disease, objective responses were seen in 48 (38%) of 126 TAM patients and 61 (47%) of 130 TAM plus PRDLN patients (chi-square, P = 0.15). Considering all 320 evaluated patients, median time to disease progression was 11 months for TAM and 10 months for TAM plus PRDLN (log rank, P = 0.81), and median survival time was 35 and 32 months, respectively (P = 0.40). Covariate analyses showed no significant association between treatment and outcome. Weight gain and edema were significantly greater with TAM plus PRDLN. The addition of PRDLN to TAM is not advocated for the management of postmenopausal women with metastatic breast cancer.

Abstract
The effects of anti-estrogen therapy (tamoxifen or toremifene) on in vitro lymphocyte functions were investigated in breast cancer patients. We found that the amount of DNA synthesis, with or without PWM stimulation, was decreased in all cancer patient groups compared to normal controls. The number of Ig-secreting cells was enhanced in unstimulated peripheral blood lymphocyte cultures but decreased in PWM-stimulated cultures. This occurred in all cancer patient groups investigated, with or without anti-estrogen therapy, as compared to healthy controls. On the other hand, subsequent samples with two-month intervals showed that anti-estrogens can increase PFC responses and inhibit DNA synthesis of peripheral blood lymphocytes in more than half of the patients. Interestingly, the enhancing dexamethasone effect, which usually causes an increase in the number of Ig-secreting cells in PWM-stimulated cultures, was also seen more often in anti-estrogen-treated patients. These results suggest that anti-estrogens may have immunoregulatory effects in vivo.

Abstract
Two hundred and twenty patients with progressive advanced breast cancer were given primary endocrine treatment (PET) according to menstrual status. Pre-menopausal patients received ovarian irradiation (O) and post-menopausal tamoxifen 10 mg bd (T). Patients were randomised to receive either no additional treatment or prednisolone 5 mg bd (P). Similar results were observed in each menstrual subgroup. In 194 evaluable patients, the response to PET + P was 49% and to PET alone 30% (P less than 0.01). P increased the median duration of response from 9 to 14 months (P less than 0.002) and the median time to disease progression from 5 to 9 months (P less than 0.001). Response to P after O or T alone occurred in only 2/62 (3%). Median survival in patients randomised to receive P at the outset of PET was prolonged by 4 months (P less than 0.05). The addition of P significantly improves the response to O or T in the treatment of advanced breast cancer.

Abstract
Serum sex hormone binding globulin (SHBG) was measured in 21 pre and 39 postmenopausal women with advanced breast cancer before treatment and 1, 3, 6, 9 and 12 months after ovarian irradiation or during continuous administration of tamoxifen at a dose of 10 mg twice daily, respectively; some patients received additional prednisolone at a dose of 5 mg twice a day. Ovarian irradiation was associated with a 25% reduction in serum SHBG levels 3 to 6 months after treatment whilst patients on tamoxifen experienced a rise of about 80% in serum SHBG levels after 1 to 3 months. In postmenopausal women prednisolone markedly dampened the effect of tamoxifen, reducing a 80% rise to about 20%. There was no relationship between SHBG levels and response to treatment.

Abstract
Recent research has resulted in several new options for endocrine treatment of advanced breast cancer. Since one of the most intriguing characteristics of endocrine therapy is that new remissions can be achieved when using subsequent endocrine modalities it is of importance to evaluate their optimal sequence. Tamoxifen has become the most commonly used endocrine therapy of advanced breast cancer due to its few side effects and an overall response rate of 35%, which has been obtained in randomized trials of tamoxifen compared with either ablative, additive or inhibitive treatment approaches. Crossover data from these trials indicate that the highest overall response rate is obtained when tamoxifen is used as first line endocrine therapy. Furthermore, it seems that oophorectomy in premenopausal and aminoglutethimide or progestins in postmenopausal patients are equally effective as second line endocrine therapy. Despite an obvious clinical rationale for combined endocrine therapy most trials exploring this concept have failed to show any benefit. Although data from trials combining tamoxifen with prednisolone or androgens seem exciting, the use of combined endocrine therapy still have to be considered experimental.

Abstract
A great deal of work has been done over the last decade in the assessment of additive hormonal treatment approaches in women with advanced breast cancer. This work has been prompted by a number of factors which include: (1) the introduction of new hormonal agents, (2) increased knowledge of the physiologic actions of several hormonal agents, (3) the development of hormonal receptor assays to better predict the probability of hormonal responsiveness in a given patient, and (4) the apparent plateau in efficacy of cytotoxic chemotherapeutic approaches. The hormonal agents that have been studied most extensively in the recent past include tamoxifen (an antiestrogen), aminoglutethimide (an aromatase inhibitor), and medroxyprogesterone acetate (a progestin). In postmenopausal women, several agents exist that appear about equal in efficacy; but, currently, tamoxifen appears to be preferred as the initial hormonal treatment, primarily because of its low incidence of side effects. Studies involving combination hormonal therapy have produced interesting results, but further work is needed to establish superiority over tamoxifen alone. In premenopausal women, tamoxifen does have antitumor activity in some patients but has not been established as a replacement for oophorectomy. Properly conducted comparative trials will remain essential for the determination of the proper place of newer hormonal therapy approaches in clinical practice.
