Blood Tests For Tumor Markers
In some cases, blood tests for tumor markers may be used to help monitor metastatic breast cancer.
For example, you may have blood tests every few months for cancer antigen 15-3 or cancer antigen 27.29 . These tests are similar. Health care providers usually check one, but not both of these blood tests.
Whether the tumor marker test score rises or falls over time may give some information on tumor response to a drug or tumor spread.
Tumor marker tests are not helpful in every case. Some people with rising tumor marker levels dont have tumor growth, and some people with tumor growth have normal or unchanged tumor marker levels.
Health care providers dont make treatment decisions based on serum tumor marker testing alone. They may combine findings from a tumor marker test with information on symptoms and findings from imaging tests . This combined information can help your health care providers understand if a treatment is working well for your cancer.
Talk with your health care provider about whether tumor marker testing is right for you.
What Does Stage 3 Mean
Because stage 3 breast cancer has spread outside the breast, it can be harder to treat than earlier stage breast cancer, though that depends on a few factors.
With aggressive treatment, stage 3 breast cancer is curable however, the risk that the cancer will grow back after treatment is high.
Doctors further divide stage 3 cancer into the following stages:

Breast Cancer Is Treatable And Curable In Early Stages
Based on the hospital’s data of OPD visits, the expert summed up that 53 per cent of cases of breast cancer could have reported early if the patients were aware that it is treatable and curable if detected in early stage 1 or 2 disease without worrying about the course of treatment.
“Today in breast cancer the medical drugs discovery has advanced so much that women even in their advanced stages of cancer can be managed with medication. As a reason, any kind of hesitancy, be it fear of undergoing chemotherapy, surgery or being diagnosed with an advanced stage of cancer should be done away with. Cancer, if not curable, can now be managed with various technologically progressed medications and therapies. As a responsible decision maker for our health, we should not let any thought come between our diagnoses,” Dr Sarin asserted.
There are various advantages associated with early cancer detection, such as better treatment outcomes, non-invasive treatment modalities or treating the diagnosed condition without a Chemotherapy.
“One should be aware towards its own health and be a responsible decision maker,” the hospital said.
If principally, we operate in a pattern that an early detection of cancer can save many lives, we should be saving millions of people we lose to cancer it concluded.
Vertical Inhibition Of The Her2 Pathway
With a vision to further improve the results obtained with trastuzumab administration in a neoadjuvant setting, lapatinib was investigated. It was hypothesized that targeting the HER2 pathway from 2 different mechanisms at the same time might improve the response rate and pCR . The trials indicated that lapatinib was inferior to trastuzumab in the rate of pCR and that it was associated with a greater toxicity . Dual HER2 blockade with the trastuzumab/lapatinib combination produced significant improvement in pCR, but unfortunately it did not translate to a significant EFS improvement . In a meta-analysis, in patients receiving a combination of lapatinib and trastuzumab in comparison to trastuzumab only combined with chemotherapy, the absolute improvement in the pCR rate was 13% .
Neoadjuvant trials with vertical blockade of the HER2 pathway
Newer tyrosine kinase irreversible inhibitors of different HER receptors, such as afatinib and neratinib, have been tested in the neoadjuvant setting with results similar to those achieved with lapatinib. In the DAFNE trial patients received a combination of paclitaxel, trastuzumab, and afatinib followed by an EC. The rate of pCR was 49.2% .

Study Design Setting And Period
A retrospective cohort study design was employed among HER2-positive breast cancer patients treated at the Kenyatta National Hospital from 1st January 2015 to 31st December 2019. The hospital is located in Nairobi, Kenya, and is the oldest and largest public referral hospital in Kenya. It was founded in 1901 as the Native Civil Hospital, with a maximum bed capacity of about 40 patients. In 1952, the hospital was renamed the King George VI hospital and subsequently became the Kenyatta National Hospital in honor of Jomo Kenyatta, Kenya’s first president.
How Is Tnbc Diagnosed
Imaging tests are usually the first tests done:
- Mammography, the most common screening tool for breast cancer, uses X-rays to take images of the breast and can uncover tumors that may be too small to feel.
- MRI uses a magnet, radio waves and a computer to make detailed images of the breast with a much greater resolution than a mammogram offers.
The next step is a biopsy to remove a sample of suspicious cells from the breast to analyze them. Techniques include:
The appropriate type of biopsy for you depends on factors such as the size and location of the tumor. You may also have a biopsy of your underarm lymph nodes at the same time to see if any cancer is there.

Progress In Treating Her2
HER2-positive and triple-negative breast cancer are among the most aggressive forms of breast cancer and traditionally have had lower survival rates than other types of the disease. However, early detection with routine screening has contributed to improved survival for both in recent years. Further, treatment advancesall available at Regional Cancer Care Associates , one of the nations largest networks of cancer specialists with locations in New Jersey, Maryland, and Connecticutalso have helped improve outcomes in HER2-positive cancer. Meanwhile, intensive research and emerging therapeutic strategies are offering new hope for women with triple-negative breast cancer.
Four RCCA medical oncologists recently explained what drives the development of these breast cancers, how they are treated, and how women can play an important and potentially life-saving role in identifying the cancers in their earliest stages, when they can be treated most effectively.
Aileen Chen, MD, a board-certified medical oncologist practicing with RCCA in Freehold and Holmdel, NJ says, Its an exciting time in the fight against breast cancer. Next-generation sequencing technology is detecting genetic mutations that we can treat with targeted therapies in many forms of the disease. This has enhanced our ability to practice personalized medicine by customizing a patients treatment based on her molecular and genetic profiles.
Chemicals And Additives To Avoid
Many chemicals used in agriculture, body care products, food packaging and plastic water bottles are estrogenic, called xenoestrogens or estrogen mimics. In addition to binding with estrogen receptors, these toxins are fat soluble, so they tend to accumulate in fat cells. We know that breast tissue has a high concentration of fat, particularly after menopause. Studies have shown that breast milk often contains dangerous levels of these chemicals. Reduce exposure by avoiding plastic food and beverage containers, canned foods, and body products with these common chemicals.

Breast Cancer Hormone Receptor Status
Breast cancer cells taken out during a biopsy or surgery will be tested to see if they have certain proteins that are estrogen or progesterone receptors. When the hormones estrogen and progesterone attach to these receptors, they fuel the cancer growth. Cancers are called hormone receptor-positive or hormone receptor-negative based on whether or not they have these receptors . Knowing the hormone receptor status is important in deciding treatment options. Ask your doctor about your hormone receptor status and what it means for you.

Detecting Breast Cancer With Screening And Awareness
One of the best ways to improve your chances of surviving breast cancer is to be vigilant about getting routine screenings for the disease. The earlier cancer is found, the better the outlook. According to the ACS, screening reduces breast cancer deaths by 20%. The ACS says that women at average risk for breast cancer should have the option of starting annual screening mammograms between ages 40 to 44 years, while women ages 45 to 54 years should have annual mammograms. Starting at age 55, women should have the option of receiving a mammogram every year or every two years, the ACS says.
Dr. Cairoli points out that younger women who arent covered by screening recommendations should not assume theyre not susceptible to breast cancer. Unfortunately, theres no such thing as too young. Breast cancers can occur in patients even in their 20s. He recommends that all women, especially those not yet of screening age, perform monthly breast self-examinations.Monthly breast self-exams havent been shown to improve outcomes for the population at large, but by knowing your body youll be able to alert your physician if you notice a change, Dr. Cairoli says. And if you do find something unusual, he adds, insist on a physical examination or screening even if your doctor tries to tell you youre too young for breast cancer.

What Is Her2 And What Does It Mean
HER2 is a protein that helps breast cancer cells grow quickly. Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than breast cancers that are HER2-negative, but are much more likely to respond to treatment with drugs that target the HER2 protein.
All invasive breast cancers should be tested for HER2 either on the biopsy sample or when the tumor is removed with surgery.

Survival Rates And Statistics
A relative survival rate helps give an idea of how long a person with a particular condition will live after receiving a diagnosis compared with those without the condition.
For example, if the 5-year relative survival rate is 70%, it means that a person with the condition is 70% as likely to live for 5 years as someone without the condition.
It is important to remember that these figures are estimates. A person can talk with a doctor about how their condition is likely to affect them.
Some factors affecting a personâs survival rate with breast cancer include:
- individual factors, such as the personâs age and overall health
- the stage of the cancer at diagnosis
- the treatment the person receives
HER2-positive cancers are than HER2-negative cancers. With treatment, however, the chances of survival are high, especially with an early diagnosis. In some cases, they may be higher than for HER2-negative breast cancer due to effective targeted treatment.
According to the , the likelihood of living for another 5 years with HER2-positive cancer, compared with a person who does not have breast cancer, is as follows. These statistics are based on figures for the years 2011â2017.

Metastatic breast cancer is advanced-stage breast cancer that has spread to parts of the body away from the breast, such as the bones or the liver. Metastatic breast cancer usually is considered treatable but not curable.
Still, a small study found that 9% of women diagnosed with HER2-positive, metastatic breast cancer that was treated with chemotherapy and the targeted therapy Herceptin were in remission for at least 3 years. Remission means there was no detectable cancer. Doctors call remission this long a durable remission. The study was presented at the September 2011 European Multidisciplinary Cancer Conference .
If you’ve been diagnosed with advanced-stage, HER2-positive breast cancer, you might want to talk to your doctor about this study and what the results might mean for your treatment plan. You can learn more about Herceptin and Tykerb by visiting the Breastcancer.org Targeted Therapies pages.

Pcr As The Primary Endpoint In Neoadjuvant Clinical Trials
The pCR rate at the time of surgery is associated with a better prognosis and provides information regarding the responsiveness of the tumor to systemic therapy. A pooled analysis defined pCR as the strongest discriminator of long-term outcomes for patients in the neoadjuvant setting . Collaborative trials in neoadjuvant breast cancer performed a meta-analysis including 12 neoadjuvant trials with 11,955 patients and follow-up of 3 years and evaluated pCR as a surrogate marker for long-term outcomes . Of all breast cancer subtypes, pCR was associated with EFS and OS . The highest pCR rates were reported in triple-negative breast cancer and HER2-positive breast cancer. Additionally, the response to neoadjuvant treatment in HER2-positive disease is dependent on the hormone receptor status. A pCR rate of 30.9% was observed in patients with HER2-positive hormone receptor-positive breast cancer with trastuzumab therapy versus 18.3% without trastuzumab and 50.3% in HER2-positive hormone receptor-negative breast cancer with trastuzumab versus 30.2% without neoadjuvant trastuzumab . Overall, patients with pCR had a longer EFS and OS .
Her2+ Breast Cancer Patients Live Longer If Drugs Given Before Surgery Eradicate Tumour
Final analysis of results from a randomised clinical trial of lapatinib and trastuzumab given before surgery in patients with early HER2-positive breast cancer has found that women who had no signs of residual disease after treatment survived longer without the cancer returning than patients who did not. This was more likely to happen in patients who received the two anti-cancer drugs together, rather than as single agents.
Speaking at the 12th European Breast Cancer Conference on Saturday, Dr. Paolo Nuciforo, principal investigator at Vall d’Hebron Institute of Oncology, Barcelona, Spain, presented results from nearly ten years of follow-up from the international NeoALTTO BIG-06 trial, in which patients were randomised to receive either trastuzumab or lapatinib alone or in combination.
He said: “Patients who achieved a pCR had significantly better long-term survival compared to those who did not achieve pCR. Although overall survival rates did not differ significantly between the three treatment groups, nearly twice as many patients achieved pCR if they received both drugs, 51% compared to 27.1% of patients receiving only one drug in the other two arms of the study combined.”

Should I Consider Participating In A Clinical Trial
Breast cancer treatment has improved tremendously. The reason for this progress is because patients have been willing to take part in tests of newer treatment options.
For any stage of breast cancer, a well done clinical trial could be your best treatment option, Dr. Abraham says. If you qualify for such a trial, your doctor can answer any questions you may have about participating so that you can determine if its a good fit for you.
What Is The Stage Of My Cancer
Cancer staging is a standardized way of classifying the severity of a patients cancer. There are various systems that use number or letter codes to designate the cancers status and how far it may have spread.
You may have heard of Stages 0 through IV, which reflect a tumors size and the extent of metastasis. A higher stage means a larger tumor and wider distribution of cancer cells.
Your doctor uses staging to plan your treatment, gauge your prognosis and communicate with other cancer specialists. What stage your cancer is in also will help determine whether youre eligible for clinical trials which offer newer treatment options.

Trastuzumab Has Radically Improved Prognosis For Her2+ Breast Cancer
HER2-positive breast cancer has gone from & quot worst to first& quot because of the success of the monoclonal antibody drug trastuzumab in combination with chemotherapy.& nbsp
Harold J. Burstein, MD, PhD
HER2-positive breast cancer has gone from “worst to first” because of the success of the monoclonal antibody drug trastuzumab in combination with chemotherapy, said breast oncologist Harold Burstein, MD, of the Dana-Farber Cancer Institute, speaking Saturday in Chicago at the 19th Annual Lynn Sage Breast Cancer Symposium, sponsored by Northwestern University’s Robert H. Lurie Comprehensive Cancer Center.
Disease-free survival rates have increased so dramatically since trastuzumab was introduced in 1998, and without significant toxicity from the drug, that, for a large proportion of patients, being diagnosed with this aggressive cancer is not the dire event it used to be.
About 1 in 5 of the 250,000 new breast cancers diagnosed every year is HER2 positive. About half are stage I and the remainder are stage II or III. Though HER2-positive cancers are more common in young women, they can occur at any age.
However, trastuzumab remains the starting point. A study of more than 4000 patients, published in 2014, showed that adding trastuzumab to chemotherapy led to a 37% relative improvement in overall survival, increasing 10-year survival from 75.2% to 84%. The 10-year disease-free survival rate increased from 62.2% to 73.7%. All patient subgroups benefited.2
