In a meta-analysis reported in JAMA Oncology, Spring et al found that neoadjuvant endocrine therapy was associated with outcomes similar to those with chemotherapy in women with estrogen receptor-positive breast cancer.. Similar Outcomes. The analysis included 3,490 patients from 20 randomized trials of neoadjuvant therapy containing ≥ 1 endocrine therapy arm. Compared with combination chemotherapy, endocrine therapy alone was associated with a similar clinical response rate (odds ratio [OR] = 1.08, P = .85), radiologic response rate (OR = 1.38, P = .12), and breast-conserving surgery rate (OR = 0.65, P = .07), with endocrine therapy alone being associated with reduced toxicity. Compared with tamoxifen, aromatase inhibitor use was associated with a better clinical response rate (OR = 1.69, P , .001), radiologic response rate (OR = 1.49, P , .001), and breast-conserving surgery rate (OR = 1.62, P , .001). Compared with endocrine therapy alone, dual combination therapy with growth factor pathway ...
In a recent committee opinion, the American College of Obstetricians and Gynecologists (ACOG) approved the use of low-dose vaginal estrogen products to relieve vaginal dryness, painful sex and related symptoms in women treated for hormone receptor-positive breast cancer.Such products - estrogen-based creams, vaginal rings and vaginal tablets - may be used when non-hormonal treatments have proven unsuccessful, ACOG noted. Women should receive information on the possible benefits and risks of vaginal estrogen use and coordinate the decision with their oncologist, the group stated.
Bodily Hormone PRP Treatment or even HRT is actually an extensive condition which involves the many different sorts of procedures for hormonal agent imbalances that can easily develop during adolescence as well as pregnancy. Procedure making use of hormone blockers, hormonal agent releasers or hormone mimickers can also be actually called HRT or even postmenopausal bodily hormone therapy.. The primary function of HRT is actually to stop any sort of increase and reduce in the amount of the sex hormonal agent, estradiol (additionally understood as estrogen). It may likewise trigger mood swings, body weight gain, genital dry skin as well as menopausal signs and symptoms such as hot flashes as well as evening perspirations.. To useful link address hormone-related concerns, HRT works by either restraining the creation of estrogens or blocking their absorption right into the blood stream by means of the ovary. There are numerous different medicines that are actually on call to regulate or even lessen ...
ER-positive breast cancer is commonly treated with adjuvant endocrine therapies. Adjuvant endocrine treatment has been shown to increase overall survival and in light of recent studies is likely to be recommended for even longer duration in the adjuvant setting (40, 41). However, many patients do not benefit from these therapies and predictors for response or resistance to endocrine treatment are urgently needed. In this study, we report a meta-analysis of two genome-wide studies and two validation datasets for identifying genetic variants associated with breast cancer-related mortality specifically after adjuvant endocrine treatment. In a meta-analysis involving individuals treated with adjuvant endocrine therapy, we identified SNP rs8113308 specifically and significantly predicting outcome after endocrine treatment. We were further able to show that among patients with ER-positive tumors, there is a significant interaction between the rs8113308 and endocrine treatment, indicating a predictive, ...

In this investigation, we delineate a pathway involving the MutL complex, along with ATM, CHK2, and CDK4/6 that is required for ER+HER2− tumors to respond to endocrine therapy (Fig. 6G). When components of this pathway are poorly expressed or lost through mutation, feedback control on CDK4/6 is defective. This allows the cell cycle to proceed despite DNA mismatches, thereby promoting the growth of high mutation load ER+ breast cancers that are intrinsically resistant to endocrine treatment, but still sensitive to CDK4/6i.. The sequential triple biopsy design of the NeoPalAna trial was executed to determine the effects of CDK4/6i on ER+ HER2− tumors where intrinsic endocrine therapy resistance had been demonstrated. Consistent with our model, CDK4/6i was uniformly effective in suppressing residual proliferation in MutL−ER+ breast cancers, with almost undetectable Ki67 levels after approximately 2 weeks of palbociclib exposure. In contrast, the degree to which each mutant MutL allele or ...

This phase II trial was designed to determine the feasibility of adjuvant palbociclib and endocrine therapy for early breast cancer. Patients and methods: Eligible patients with HR+/HER2- stage II-III breast cancer received 2 years of palbociclib at 125 mg daily, 3 weeks on/1 week off, with endocrine therapy. The primary end ...
Clinical equipoise exists around the optimal time to start adjuvant endocrine therapy in patients who will receive post-operative radiotherapy for breast cancer. Patients receive either concurrent or sequential endocrine and radiation therapy, where concurrent therapy consists of endocrine therapy started before, with or during radiotherapy, while sequential treatment is defined as endocrine therapy starting after the completion of radiotherapy. A recent survey of Canadian oncologists showed that the main reason for prescribing sequential endocrine therapy was a concern that concurrent endocrine therapy and radiotherapy would worsen the toxicity of endocrine treatment. This is despite the absence of any clinical trial evidence to support this. Indeed, a recent systematic review by our group was unable to confirm or refute whether increased toxicities, related to the timing of endocrine therapy and radiotherapy actually exist in clinical practice. The investigators are therefore proposing a ...
BACKGROUND: As trials of 5 years of tamoxifen in early breast cancer mature, the relevance of hormone receptor measurements (and other patient characteristics) to long-term outcome can be assessed increasingly reliably. We report updated meta-analyses of the trials of 5 years of adjuvant tamoxifen. METHODS: We undertook a collaborative meta-analysis of individual patient data from 20 trials (n=21,457) in early breast cancer of about 5 years of tamoxifen versus no adjuvant tamoxifen, with about 80% compliance. Recurrence and death rate ratios (RRs) were from log-rank analyses by allocated treatment. FINDINGS: In oestrogen receptor (ER)-positive disease (n=10,645), allocation to about 5 years of tamoxifen substantially reduced recurrence rates throughout the first 10 years (RR 0.53 [SE 0.03] during years 0-4 and RR 0.68 [0.06] during years 5-9 [both 2p|0.00001]; but RR 0.97 [0.10] during years 10-14, suggesting no further gain or loss after year 10). Even in marginally ER-positive disease (10-19 fmol/mg
Although mechanisms of acquired resistance to endocrine therapy have been identified in estrogen receptor-positive (ER+) breast cancer, the causes of intrinsic resistance, present at the time of diagnosis, are less well understood. Haricharan and colleagues linked loss of the MutL mismatch repair (MMR) complex to intrinsic resistance to endocrine therapy. MMR has two damage-sensing complexes: MutS and MutL. In patients with ER+ breast cancer, endocrine therapy resistance was associated with dysregulation of MutL but not MutS. In ER+ breast cancer cell lines, silencing of MutL complex genes promoted resistance to endocrine therapy (including estrogen deprivation, a surrogate for aromatase inhibitor exposure, fulvestrant, and tamoxifen) by preventing CHK2-mediated inhibition of CDK4/6, resulting in deregulated CDK4/6 activity that drove endocrine therapy resistance. Further, mutations that dysregulated MutL promoted resistance to endocrine therapy in patient-derived xenograft models. Response to ...
The majority of breast cancer patients discontinues todays standard adjuvant treatment (endocrine therapy) due to side effects and reduced quality of life. Thereby, most side effects are unspecific, suggesting a role of psychological factors as patients´ expectations (nocebo effects). Moreover, patients are not informed sufficiently about their treatment.. Using a longitudinal design, the nature and onset of adverse side effects and their association to treatment related expectations are investigated. Postoperative patients with hormone receptor-positive breast cancer are assessed before the start of adjuvant treatment. All patients receive standardized, additional information about endocrine therapy. Expectations about side effects, knowledge and satisfaction with the enhanced information are assessed before and after informing patients. Side effects, quality of life and adherence are measured three months, two and five years after start of medication intake.. It will be analyzed if patients ...

BACKGROUND:The cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor palbociclib, in combination with fulvestrant therapy, prolongs progression-free survival among patients with hormone-receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer. We report the results of a prespecified analysis of overall survival. METHODS:We randomly assigned patients with hormone-receptor-positive, HER2-negative advanced breast cancer who had progression or relapse during previous endocrine therapy to receive palbociclib plus fulvestrant or placebo plus fulvestrant. We analyzed overall survival; the effect of palbociclib according to the prespecified stratification factors of presence or absence of sensitivity to endocrine therapy, presence or absence of visceral metastatic disease, and menopausal status; the efficacy of subsequent therapies after disease progression; and safety. RESULTS:Among 521 patients who underwent randomization, the median overall survival was 34.9 ...
Anavar is a dihydrotestosterone (DHT) acquired anabolic androgenic steroid. Specifically, this is an altered kind of the DHT hormonal agent; it is the DHT hormonal agent with an added oxygen atom replacing the carbon-2 in the A-ring. This structural adjustment protects against the hormonal agent from being metabolically broken down, along with enhances its anabolic task substantially. There is also a 2nd change of worthwhile note in that there is a structural change to the hormonal agent at the 17th carbon placement through the enhancement of an included methyl group. This change enables the hormone to make it through dental ingestion and officially categorizes Anavar as a C17-alpha alkylated (C17-aa) anabolic steroid. This additionally creates the steroid to lug a hepatotoxic nature, although reasonably light.. Although frequently described as a light steroid, Anavar is very anabolic; as a matter of fact, its anabolic ranking is 3-6 times more powerful compared to testosterone resting at ...

In this issue of Clinical Cancer Research, Fox and colleagues report a prospective tamoxifen dose-escalation study in patients with low endoxifen concentrations during treatment (1). Tamoxifen is highly effective for preventing recurrence of hormone receptor (HR+) breast cancer; however, approximately 15% of patients will recur within 5 years despite adjuvant treatment (2). Tamoxifen is believed to be a prodrug with part of the antiestrogen activity attributed to endoxifen, which is produced primarily via CYP2D6-catalyzed metabolism. There is substantial variability in endoxifen concentration in patients on tamoxifen treatment, and there is some evidence that patients with low endoxifen concentrations during tamoxifen treatment are at increased risk of cancer recurrence (3, 4). On the basis of this putative association between endoxifen concentration and tamoxifen treatment efficacy, several studies have prospectively dose-escalated patients who have low-activity CYP2D6 genotype and predicted, ...

I am so glad I found this blog! Ive been on tamoxifen for 14 months. They really should have a warning label that says will alter your life on the bottle!!!! I had stage 1b BC ER/PR positive at age 38, did not reach my lymph nodes, thank god, no chemo or radiation. I quickly became depressed after I started taking the tamoxifen, I thought I was going through depression due to all the fear & scare I had gone through. Plus my reconstruction had been very painful & couldnt find any answers as to why it was so painful, so I was depressed. My period was normal until I took the tamoxifen, it changed to every 5 to 6 weeks instead of 4 & was very light. Over time it went back to my regular flow & time. I decided to start a period tracker app on my phone, thought it would be a good idea. About 6 months after taking tamoxifen I noticed that my mood was like a light switch & the depression was so bad, plus cramps body aches,loss of sex drive, fog you name it. The brain fog is the worst for me I cant ...

Steroid hormones mediate critical lineage-specific developmental and physiologic responses. They function by binding their cognate receptors, which are transcription factors that drive specific gene expression programs. The requirement of most prostate cancers for androgen and most breast cancers for estrogen has led to the development of endocrine therapies that block the action of these hormones in these tumors. While initial endocrine interventions are successful, resistance to therapy often arises. We will review how steroid receptor-dependent genomic signaling is affected by genetic alterations in endocrine therapy resistance. The detailed understanding of these interactions will not only provide improved treatment options to overcome resistance, but, in the future, will also be the basis for implementing precision cancer medicine approaches.. ...
This is a two stage study, with an initial dose escalation phase I study and subsequent double blind randomised phase II controlled trial. Eligible patients are post-menopausal women with metastatic ER+ breast cancer not suitable for surgical resection. Patients should be suitable for endocrine treatment, but have received no more than 3 previous lines of endocrine treatment and up to 1 line of chemotherapy for metastatic disease. They will also have had progressive disease during treatment with an aromatase inhibitor. Following the dose-escalation in stage 1, patients will be randomised to receive fulvestrant plus either placebo or 480mg (or maximum tolerated dose) of AZD5363 oral capsules or tablets taken once daily. Patients will receive fulvestrant in combination with either placebo or AZD5363 until disease progression. Patients may continue to receive fulvestrant and AZD5363/placebo treatment even after the last trial visit. ...
