Digital breast tomosynthesis may improve breast cancer detection

It was serious and surprising. . Jenny always assumed a negative mammogram meant she didnt have breast cancer. . Every woman should find out if they have dense breast tissue because it increases the likelihood of cancer in the breast and it is harder to detect. . ive linked a short article entitled, few Aware that Dense Breasts Increase cancer Risks from Cure magazine (Winter 2014). . It is a year old. . Forty percent of women have dense breast tissue, which is composed more of connective tissue than of fat. . Research is being done to determine whether imaging with ultrasound, mri or tomosynthesis which generates three-dimensional images might increase the effectiveness of breast cancer screening for those women. As a mean of ensuring that women are informed so that they can initiate discussion with their health care providers, 19 American states have passed legislation requiring that women be notified if a mammogram shows they have dense breast tissue, and 12 states have such.

The bilateral digital screen mammogram came back negative. . But the letter went onto say, your mammogram indicates that you may have dense breast tissue. . Dense breast tissue is relatively common and is found in more than forty percent (40) of women. . The presence of dense tissue may make it more difficult to detect abnormalities in the breast and may be associated with an increased risk of breast cancer. The qualification about more difficult to detect abnormalities (e.g. Cancerous tumors) didnt register until a couple months later when Jenny started noticing short changes in her breast and began experiencing some pain and soreness. . At that point, she saw her primary care physician who did a physical examination. . That was followed by an appointment with a highly regarded radiologist who used the latest technology and performed a three-dimensional mammogram (a.k.a. he also did an ultrasound. . The radiologist and his assistant shared the results on December. .

The decision is based on the totality of data, including 3 trials in first-line treatment of metastatic breast cancer (E2100, avado, and ribbon-1 as well as the evf 2119 trial for second-line treatment in this setting. The bevacizumab data review found that patients treated with bevacizumab did not live any longer than patients who reviews were not taking it, but they were at greater risk of adverse effects, including those unique to bevacizumab, such as gastrointestinal perforations, which can be life threatening. Other serious and potentially life-threatening effects include the risk of stroke, wound-healing complications, and organ damage or failure; bevacizumab has also been linked with the neurological condition reversible posterior leukoencephalopathy syndrome (rpls).

The rate of grade 3 or higher adverse events was.6 in remote the olaparib group and.5 in the standard-therapy group. Overall survival and median time to death did not differ significantly between the 2 treatment arms after a median follow-up of 14 months (45.9.4;.3 months.6 months). 152 Treatment of her2-positive metastatic breast cancer see her2 Breast Cancer for more information on this topic. Antiangiogenic therapy in metastatic breast cancer Angiogenesis is recognized as a key process in the progression and metastasis of breast cancer. Bevacizumab (Avastin) is a humanized mAb directed against vascular endothelial growth factor (vegf legs which exerts an independent effect on the process of new blood vessel formation in tumors (angiogenesis). Bevacizumab was approved by the fda as a first-line therapy for her2-negative metastatic breast cancer patients, based on results from the phase iii ecog 2100 trial. However, on november 18, 2011, the fda officially rescinded its approval of bevacizumab because the drug had not been shown to be safe and effective for this use.

In January 2018, the fda expanded approval of olaparib to include treatment of brca -mutated, her2-negative metastatic breast cancer in patients who have been previously treated with chemotherapy. Olaparib (which had previously been approved for treatment of brca -mutated ovarian cancer) is the first parp inhibitor approved to treat breast cancer, and the first drug of any kind approved to treat certain patients with brca -mutated metastatic breast cancer. 151 Approval was based on the Olympiad clinical trial, which was the first phase iii trial to demonstrate that parp inhibitors are superior to chemotherapy for this class of patients. . In this trial, patients with a germline brca mutation and her2-negative metastatic breast cancer were assigned to receive either olaparib 300 mg po bid (n205) or standard therapy (n92). Standard therapy was a choice of single-agent chemotherapy, which consisted of 21-day cycles of capecitabine (2500 mg/m2 po on days 1-14 vinorelbine (30 mg/m2 iv on days 1 and 8 or eribulin (1.4  mg/m2 iv on days 1 and 8). Median progression-free survival (PFS) was significantly longer in those who received olaparib compared with standard therapy (7.0 months.2 months; hazard ratio,.58;.0009). 152 The objective response rate was.9 in the olaparib group and.8 in the standard-therapy group.

Vinorelbine is often used as a single agent following treatment with a taxane or essay anthracycline, yielding an orr. However, when used as a first- or second-line agent, vinorelbine can have orrs of up. Palbociclib (Ibrance) is an inhibitor of cyclin-dependent kinases (CDKs) 4 and 6 used for first-line treatment for er-positive, her2-negative metastatic breast cancer in postmenopausal women, in combination with the aromatase inhibitor letrozole. 148 A phase ii study in which progression-free survival (PFS) for women receiving palbociclib and letrozole was.2 months, versus.2 months for those on letrozole alone (P.0004). 148, 149 The cdk 4,6 inhibitor ribociclib (Kisqali) was approved by the fda in March 2017 for postmenopausal HR/her- advanced or metastatic breast cancer in combination with letrozole. Approval was based on interim analysis results from extended the phase iii monaleesa-2 trial in postmenopausal women who had received no prior systemic therapy for their advanced breast cancer (n668). Ribociclib plus letrozole yielded a pfs rate of 63 with a duration.3 months, compared with a rate.2 and a duration.7 months with letrozole alone.

139 since those data were published, a subsequent analysis with an additional 11 months of follow-up showed that the median pfs was.3 months with the ribociclib combination versus 16 months with letrozole alone, according to a company statement. 150 As with hormone therapy, the likelihood of benefit from chemotherapy is related to the success achieved with the previous regimen. Although there are occasional gratifying responses to a drug used in the third- or fourth-line setting of metastatic breast cancer, they are the exception rather than the rule. Thus, patient characteristics, previous treatments, and the expected toxicity of these regimens must be taken into account. Parp inhibitors Olaparib inhibits poly (adp-ribose) polymerase (parp) enzymes. .

At least one third of breast cancer patients with taxane resistance due to administration of every-3-week paclitaxel show a response when the same drug is administered on a weekly schedule at a lower dose. The cancer and leukemia group B (calgb) 9840 trial reported an improved overall response rate (ORR) in patients receiving weekly dosing of paclitaxel (40) compared with every-3-week paclitaxel (28 as well as improved median time to progression (9 mo vs 5 mo). However, care should be taken in watching for progression of adverse effects, especially neuropathy. In addition to taxanes and anthracyclines, a variety of other chemotherapeutic agents can be used as single agents or in combination with taxanes. Capecitabine (Xeloda) is an oral agent that essentially represents a sustained-release formulation of the older antimetabolite fluorouracil (5-FU) and provides the convenience of self-administration. Drugs such as capecitabine have very little associated myelosuppression, and they are often chosen when the patient's bone marrow has been damaged by previous therapy or when there is a desire to coadminister a myelosuppressive agent for more rapid effect.

As a single agent, capecitabine has an orr of 25-30, with minimal toxicity. When combined with a taxane, an orr of 40-50 has been observed, along with a median overall survival benefit of 3-15 months. Another antimetabolite, gemcitabine (Gemzar is typically given in combination with paclitaxel, based on results from a phase iii trial comparing paclitaxel with the combination regimen in locally advanced breast cancer (labc) and metastatic breast cancer. A total of 529 patients were randomized to receive paclitaxel 175 mg/m2 on day 1 plus gemcitabine 1250 mg/m2 on days 1 and 8, or receive the same dose of paclitaxel alone every 3 weeks. Orr (41 vs 26) and overall survival (18.6 mo.8 mo) were significantly higher with the paclitaxel/gemcitabine arm than with paclitaxel alone. 147 vinorelbine (navelbine) is a vinca alkaloid that targets tubulin in the mitotic spindle and is administered intravenously, usually on a weekly basis.

Combination Regimens for Metastatic Breast Cancer (Open Table in a new window) Chemotherapy dose and Schedule cycle xt capecitabine docetaxel 1250 mg/m bid days 1-14 75 mg/m day 1 Repeat cycle every 21 days may decrease capecitabine dose to mg/m to reduce toxicity risk. References for chemotherapy regimens: xt, 141 xp, 142 xn, 142 her2-positive metastatic breast cancer regimens 143, 144, 145, 146 The initial choice of chemotherapy is highly margaret influenced by the patient's personal history of previous drug exposure. For example, if doxorubicin was a component of previous adjuvant therapy, the tumor cells have a higher risk of developing resistance, and there is a relationship between cumulative lifetime total dose of doxorubicin and the risk of potentially fatal cardiomyopathy. It is important to realize that if 1 year or roles more has elapsed since completion of adjuvant therapy, a patient's tumor is likely to respond to a previously given drug or combination as though that drug or combination had never been given. Most patients have been exposed to both an anthracycline (ie, doxorubicin) and a taxane (docetaxel or paclitaxel) in the adjuvant setting. Treatment of breast cancer with a taxane in the metastatic setting after treatment in the adjuvant setting may be difficult because of residual toxicity. Although taxanes are not cardiotoxic, they can produce lingering neuropathy (especially paclitaxel) or problems with edema (docetaxel especially which makes further administration problematic. Substitution of one taxane for another is possible, depending on the nature of the chronic toxicity. If the tumor has recurred quickly after administration of adjuvant chemotherapy containing a taxane, then changing the schedule of administration can be effective.

Combination therapy is currently considered up front, depending on the patient's performance status, because master of higher response rates. However, in the setting of advanced disease, the goal in determining a treatment regimen should be to prolong survival while maintaining a good quality of life. When the patient has life-threatening disease and/or severe symptoms that require quick relief, combinations of cytotoxic agents may be preferable because of their high response rate and early onset of clinical benefit. Randomized trials have shown a survival advantage for the use of a two-drug combination versus a single agent, but this practice has not been widely adopted, because the combination is more toxic and the study designs were flawed in that patients randomized to receive. A second situation, which is becoming increasingly common, is when a cytotoxic chemotherapeutic agent is combined with a targeted agent other than hormone therapy. These targeted agents often have very low response rates when given as monotherapy, but they provide added benefit when given in combination with cytotoxic chemotherapy. A list of targeted chemotherapeutic agents is provided in Table 6, below, followed by table 7, showing combination regimens for breast cancer. Targeted Chemotherapy for Metastatic Breast Cancer (Open Table in a new window) Drug Class Dose/Schedule overall Response rate (ORR) Toxicity Abemaciclib cdk inhibitor 200 mg po bid continue until disease progression.7 diarrhea, fatigue, neutropenia and nausea capecitabine Oral fluoro-pyrimidine 1250 mg/m/d po for.

In a randomized study, mehta et al found that combination treatment with anastrozole and fulvestrant was superior to either anastrozole alone or sequential anastrozole and fulvestrant treatment in patients with hormone-receptor-positive metastatic breast cancer. 133, in the international, double-blind phase iii monarch 2 trial, 669 patients were randomized in a 2:1 ratio to abemaciclib (a cdk inhibitor) plus fulvestrant or fulvestrant plus placebo. Patients received 500 mg of fulvestrant plus placebo or 150 mg of abemaciclib twice daily. The median progression-free survival was.4 months in the abemaciclib arm versus.3 months in the fulvestrant-alone group. The overall response rates among patients with measurable disease were.1 and.3 in the abemaciclib and control arms, respectively. 134, chemotherapy cytotoxic chemotherapy for metastatic breast cancer initially consisted of single-agent regimens.

For ERpositive metastatic breast cancer, the American Society of Clinical Oncology (asco) recommends using endocrine therapy rather than chemotherapy as first-line treatment, except in patients with immediately pdf life-threatening disease or if there are concerns about endocrine resistance. The recommendation is part of an asco clinical practice guideline on the use of chemotherapy and targeted therapy for women with human epidermal growth factor 2 (HER2)-negative (or unknown) advanced breast cancer, with recommendations based on a systematic review of 79 studies. 132, a trial of hormone manipulation alone can assess whether hormone therapy is effective, which is impossible to determine if it is given together with cytotoxic chemotherapy. This is especially important when the patient has relapsed disease, because the benefit of second-line hormone manipulation is nearly 50, and failure to benefit from an initial trial with endocrine therapy correlates with second-line failure. Common hormone therapies and dosages are listed in Table 5, below. Hormone Agents Used in Breast Cancer (Open Table in a new window). Agent, dose and Schedule, postmenopausal, tamoxifen 20 mg po every day,. Anastrozole 1 mg po every day, letrozole.5 mg po every day.

Marked advances are being made in the treatment of early-stage breast cancer, but many women still develop recurrence and metastasis. In addition, 5-10 of breast cancer patients have metastatic disease at presentation. Although treatments for metastatic breast cancer continue to improve, there remains no cure once distant metastases develop. Furthermore, although occasional patients with metastatic breast cancer benefit from surgical resection for an isolated recurrence and many require radiation therapy the for palliation at a specific site (or definitive treatment of brain metastasis in general, recurrent or metastatic breast cancer must be approached systemically. There are two main interventions: hormone therapy and chemotherapy. Hormone therapy, for patients who have hormone receptor (er and/or PR)positive disease without a life-threatening component (eg, massive liver metastases) or systemic symptoms requiring immediate palliation for comfort, in general, hormone manipulation is the initial treatment of choice. Response rates are higher with chemotherapy, but so is the incidence of potentially dangerous toxicity, and there is no evidence that patients live longer as a result of receiving initial chemotherapy.
