What is DCIS and how is it treated?
DCIS is treated to try to prevent the development of invasive breast cancer. DCIS can be found alone or with invasive breast cancer. If DCIS is diagnosed with invasive breast cancer, treatment and prognosis are based on the invasive breast cancer (not the DCIS). Learn about treatment for early breast cancer.
What is comedo-type ductal carcinoma in situ (DCIS)?
A comedo-type ductal carcinoma in situ, also known as comedocarcinoma in situ is the high grade subtype of ductal carcinoma in situ (DCIS). It completely fills and dilates the ducts and lobules in TDLU with plugs of high grade tumour cells with central necrosis "comedonecrosis". It is the most aggressive of intraductal carcinomas.
What is the difference between DCIS comedo and invasive foci carcinoma?
Sometimes an ‘irregular circumference’ of invasive foci carcinoma is evident when compared to true DCIS comedo circumference, (which is more regular). Most invasive breast cancers will lack both a basement membrane and myoepithelial cells. However, in actuality, there are many breast cancers that produce basement membrane components.
What is high grade DCIS with comedo necrosis?
High-grade DCIS has a higher risk of coming back than low- or moderate-grade DCIS. High-grade DCIS may be described as comedo or comedo necrosis, which means there are areas of dead cancer cells inside the DCIS.
What is best treatment for high grade DCIS?
Radiation therapy Treatment of DCIS has a high likelihood of success, in most instances removing the tumor and preventing any recurrence. In most people, treatment options for DCIS include: Breast-conserving surgery (lumpectomy) and radiation therapy. Breast-removing surgery (mastectomy)
What is the treatment for DCIS with Microinvasion?
(See "Microinvasive breast carcinoma".) TREATMENT APPROACH Patients with DCIS undergo local treatment with breast-conserving therapy (BCT) or mastectomy. BCT consists of lumpectomy (also called breast-conserving surgery, wide excision, or partial mastectomy) followed in most cases by adjuvant radiation.
How long does it take for DCIS to turn into invasive cancer?
It assumes that all breast carcinomas begin as DCIS and take 9 years to go from a single cell to an invasive lesion for the slowest growing lesions, 6 years for intermediate growing DCIS lesions, and 3 years for fast-growing DCIS lesions.
What does comedo necrosis mean?
Answer: The term 'necrosis' refers to cells that are dying. When cells die, they often attract other chemicals in the body, and form something called 'comedo necrosis,' which is basically the residual, leftover dead cells.
What is the survival rate for high grade DCIS?
Multivariate analysis found that high grade DCIS is the only independent risk factors for margin involvement (HR 2.55, 95% CI 1.02-6.42). After median follow-up of 106 months (6-223 months), the overall survival was 97%.
How serious is DCIS with Microinvasion?
Synopsis. DCIS with microinvasion is a rare diagnosis with an excellent prognosis and a low rate of nodal involvement. This study attempts to identify factors associated with a positive sentinel lymph node biopsy and provides outcome data on these patients.
How long can you wait for DCIS surgery?
In women with a clinical diagnosis of DCIS, greater delay to surgery is associated with lower OS. Although most women with DCIS undergo surgical extirpation within 2 months of diagnosis, longer time to surgery is associated with greater risk of finding invasion and should be limited.
Is Tamoxifen necessary after DCIS?
Research shows that radiation therapy and hormonal therapy after surgery for DCIS reduces the risk of being diagnosed with either another DCIS or invasive breast cancer in the future.
How do you know if DCIS has spread?
The doctor will remove a bit of tissue to look at under a microscope. They can make a diagnosis from the biopsy results. If the biopsy confirms you have cancer, you'll likely have more tests to see how large the tumor is and if it has spread: CT scan.
Should I have a mastectomy for DCIS?
In most cases, a woman with DCIS can choose between breast-conserving surgery (BCS) and simple mastectomy. But sometimes, if DCIS is throughout the breast, a mastectomy might be a better option. There are clinical studies being done to see if observation instead of surgery might be an option for some women.
Can DCIS come back after lumpectomy?
A study found that radiation therapy given after DCIS is removed by lumpectomy reduces the risk that the DCIS will come back (recurrence).
What is a DCIS?
Treatment of Ductal Carcinoma in Situ (DCIS) Ductal carcinoma in situ (DCIS) means the cells that line the milk ducts of the breast have become cancer, but they have not spread into surrounding breast tissue. DCIS is considered non-invasive or pre-invasive breast cancer.
What is BCS in surgery?
Breast-conserving surgery (BCS) In breast-conserving surgery (BCS), the surgeon removes the tumor and a small amount of normal breast tissue around it. Lymph node removal is not always needed with BCS, but it may be done if the doctor thinks the area of DCIS might also contain invasive cancer.
What hormones are used after breast surgery?
Hormone therapy after surgery. If the DCIS is hormone receptor-positive (estrogen or progesterone), treatment with tamoxifen (for any woman) or an aromatase inhibitor (for women past menopause) for 5 years after surgery can lower the risk of another DCIS or invasive cancer developing in either breast. If you have hormone receptor-positive DCIS, ...
Does DCIS have invasive cancer?
The chances an area of DCIS contains invasive cancer goes up with tumor size and how fast the cancer is growing. If lymph nodes are removed, this is usually done as a sentinel lymph node biopsy (SLNB ). If BCS is done, it is usually followed by radiation therapy. This lowers the chance of the cancer coming back in the same breast ...
Is DCIS invasive or noninvasive?
DCIS is considered non-invasive or pre-invasive breast cancer. DCIS can’t spread outside the breast, but it still needs to be treated because it can sometimes go on to become invasive breast cancer (which can spread).
Can you get BCS without radiation?
BCS without radiation therapy is not a standard treatment, but it might be an option for certain women who had small areas of low-grade DCIS that were removed with large enough cancer-free surgical margins.
Can you do SLNB after mastectomy?
This is because if an area of invasive cancer is found in the tissue removed during a mastectomy, the doctor won’t be able to go back and do the SLNB later, and so may have to do a full axillary lymph node dissection (ALND).
How to treat DCIS?
Surgery is the first step to treat DCIS. It removes the abnormal tissue from the breast. Depending on how far the DCIS has spread within the milk ducts, surgery can be mastectomy or lumpectomy. If DCIS is spread throughout the ducts, affecting a large part of the breast, a total (simple) mastectomy will be done.
What is the treatment for DCIS?
In the U.S., most women with DCIS are treated with lumpectomy followed by radiation therapy [ 7 ].
What does it mean when a DCIS tumor is estrogen receptor negative?
Hormone receptor-negative (estrogen receptor-negative/progesterone receptor-negative) DCIS tumors do not express hormone receptors. This means they have few or no hormone receptors.
Why do you need an axillary dissection?
An axillary dissection removes more axillary lymph nodes than a sentinel node biopsy. Because it disrupts more of the normal tissue in the underarm area, axillary dissection is more likely to affect arm function and cause lymphedema.
Why is DCIS called in situ?
It’s called “in situ” (which means “in place”) because the cells have not left the milk ducts to invade nearby breast tissue. DCIS is also called intraductal (within the milk ducts) carcinoma. You may hear the terms “pre-invasive” or “pre-cancerous” to describe DCIS. DCIS is treated to try to prevent the development of invasive breast cancer.
What is lumpectomy in breast?
With lumpectomy, the surgeon removes only the abnormal tissue in the breast and a small rim of normal tissue around it. The rest of the breast is left intact. Lymph nodes are not usually removed with lumpectomy for DCIS.
What is DCIS in a milk duct?
DCIS is also called intraductal (within the milk ducts) carcinoma . You may hear the terms “pre-invasive” or “pre-cancerous” to describe DCIS.
What is DCIS in breast cancer?
Before the advent of routine mammography, DCIS (ductal carcinoma in situ) was rarely detected. But today, DCIS accounts for 20% of breast cancer diagnoses and would be the fifth most common cancer in women if classified independently. Often called “stage zero breast cancer,” DCIS growths are confined to the inside of the breast’s milk ducts, ...
How long does DCIS treatment last?
Thus far, we have been focused on reducing that risk at all costs and treating DCIS like an early-stage breast cancer: The first step is surgery—usually lumpectomy—followed by radiation treatment for three to four weeks and finally hormone therapy for five years.
How long does it take to survive DCIS?
It’s important to understand that radiation and hormone treatments do not change survival—the 10-year survival rate for women diagnosed with DCIS is 98% regardless of whether they receive either treatment. These treatments instead reduce the risk of breast cancer down the road.
Where is stage zero breast cancer?
Often called “stage zero breast cancer,” DCIS growths are confined to the inside of the breast’s milk ducts , and many never develop into invasive cancers. Several treatment options are available, and opinions about the optimal treatment for DCIS vary widely among doctors.
Can hormone therapy be used for DCIS?
However, not all treatments for invasive breast cancer may be optimal for DCIS, Gupta says. His study suggests that in most cases of DCIS, the side effects of hormone therapy may outweigh its benefits. The CUIMC Newsroom spoke with Gupta to learn how the study’s findings can help providers and their patients navigate treatment for DCIS.
Is radiation therapy better for DCIS patients?
For patients with low-risk DCIS, though our study found that the benefits of radiation therapy are lower relative to its costs, if a patient is anxio us about the risk of recurrence, it may make sense to pursue radiation—her quality of life will be better because we reduced her anxiety.
Is DCIS a pre-invasive cancer?
“DCIS is considered a pre-invasive cancer, but the current standard of care is to treat it like an early-stage invasive breast cancer,” says Apar Gupta, MD, ...
How to get rid of DCIS?
Treatment is aimed at getting rid of all the DCIS, usually by surgery. In some cases, radiation (radiotherapy) or hormone therapy (like tamoxifen) is given after surgery to lower the chance that it will come back later (recur) or that invasive carcinoma will occur.
What if my report on ductal carcinoma in situ (DCIS) mentions margins or ink?
When the entire area of DCIS is removed, the outside surface (edges or margins) of the specimen is coated with ink, sometimes even with different colors of ink on different sides of the specimen. The pathologist looks at slides of the DCIS under the microscope to see how close the DCIS cells get to the ink (the edges or margins of the specimen). If DCIS is touching the ink (called positive margins ), it can mean that some DCIS cells were left behind, and more surgery or other treatments may be needed. Sometimes, though, the surgeon has already removed more tissue (at surgery) to help make sure that this isn’t needed. If your pathology report shows DCIS with positive margins, your doctor will talk to you about what treatment is best.
What is the significance of the reported size of the ductal carcinoma in situ (DCIS)?
If the entire tumor or area of DCIS is removed (such as in an excisional biopsy or breast-conserving surgery ), the pathologist will say how big the DCIS is by measuring how long it is across (in greatest dimension), either by looking at it under the microscope or by gross examination (just looking at it with the naked eye) of the tissue taken out at surgery. Another way to measure DCIS is to note the number of microscopic slides that contain DCIS. For example, the report may say that DCIS was found in 3 slides.
What does it mean when DCIS touches ink?
If DCIS is touching the ink (called positive margins ), it can mean that some DCIS cells were left behind, and more surgery or other treatments may be needed. Sometimes, though, the surgeon has already removed more tissue (at surgery) to help make sure that this isn’t needed.
What grade is DCIS?
DCIS that is high grade, is nuclear grade 3 , or has a high mitotic rate is more likely to come back (recur) after it is removed with surgery.
What is it called when a tumor breaks out?
Once the carcinoma cells have grown and broken out of the ducts or lobules, it is called invasive or infiltrating carcinoma. In an invasive carcinoma, the tumor cells can spread (metastasize) to other parts of your body.
Can you measure DCIS?
On needle biopsy, measurements of the area of DCIS are not often reported because this type of biopsy only samples a part of the tumor. Later, when the entire area of DCIS is removed (with surgery), an accurate measurement can be done.
What is the best treatment for DCIS?
Doctors recommend this type of treatment for DCIS that is hormone-receptor-positive -- which means it responds to the hormone estrogen.
How to treat DCIS?
Surgery is the most common way that doctors treat DCIS. Most often, it’s done with a procedure called a lumpectomy. A surgeon removes only the affected area of the breast while leaving healthy tissue. Doctors also call this breast-conserving surgery. Sometimes, a doctor might suggest removing the whole breast.
Will I Need Another Surgery?
It’s possible. Sometimes after a first lumpectomy, a doctor may need to do a second one. This usually happens when the tissue removed in the first surgery doesn’t have enough healthy tissue around it for doctors to be sure they got it all. At this point, you might also consider a mastectomy to make sure all the cancer is gone.
Why is breast cancer called DCIS?
Doctors often call this type of breast cancer ductal carcinoma in situ (DCIS). It gets this name because the cancer is only in the breast ducts that carry milk.
Why do doctors recommend mastectomy?
This type of surgery is a mastectomy. Reasons why a doctor might suggest you have a mastectomy instead of a lumpectomy for DCIS include: The cancer covers a large area of the breast. The cancer is in more than one place.
What to do after a lumpectomy?
After a lumpectomy or mastectomy, some women may choose to have surgery to reconstruct their breast. The decision to have breast reconstruction is a personal one.
Can you get radiation for only part of your breast?
It might be an option to get radiation for only part of the breast. It’s not clear if this works as well as whole breast radiation. Instead of using a machine, a doctor might insert a radioactive seed or pellet into your breast. It’s not yet clear if this works as well to prevent cancer from coming back.
What is the most common mammographic finding in comedotype DCIS?
Casting-type microcalcifications are the most frequent mammographic finding (78% of cases) in comedotype DCIS.
What is the term for ductal carcinoma with central necrosis?
Infiltrating ductal carcinoma (infiltrative ductal carcinoma with central necrosis) may so closely mimic the pattern of DCIS with central comedonecrosis that on initial morphological analysis these foci of tumors are often labeled as DCIS (high grade, comedo type).
What is comedo type carcinoma?
A comedo-type ductal carcinoma in situ, also known as comedocarcinoma in situ is the high grade subtype of ductal carcinoma in situ (DCIS) . It completely fills and dilates the ducts and lobules in TDLU with plugs of high grade tumor cells with central necrosis "comedonecrosis". It is the most aggressive of intraductal carcinomas.
Is intraductal carcinoma multicentric?
It is the most aggressive of intraductal carcinomas. In 30% of cases it can be multicentric and / or multifocal. Casting-type microcalcifications are the most frequent mammographic finding (78% of cases) in comedotype DCIS.
What is the treatment for lymph nodes after a mastectomy?
Post-mastectomy radiation to the chest wall and regional lymph nodes ( Answers C and D) is standard treatment after a locoregional post-mastectomy recurrence. [7] Antiendocrine therapy with an aromatase inhibitor ( Answer E) is supported by the results of the SOFT trial. [8]
What is stage 0 breast cancer?
DCIS (or stage 0 breast cancer) accounts for approximately 20% of mammographically detected breast cancers. [1] Although DCIS has become a rather common diagnosis, the biology of the disease is not well understood. The traditional pathologic classification of breast carcinoma is based on histologic subtypes; however, it is becoming increasingly clear that the extent of differentiation (grade) is a better predictor of outcome. Prognosis based on classification is mirrored in the molecular phenotype, as each of the various molecular subtypes is associated with distinct clinical behavior.
What is the treatment for a node positive recurrence?
Given her invasive and node-positive recurrence, and in light of its histology, we recommended systemic treatment with dose-dense doxorubicin and cyclophosphamide and weekly paclitaxel chemotherapy, followed by surgery ( Answer A ). The use of chemotherapy in this setting is supported by the Chemotherapy for Isolated Locoregional Recurrence of Breast Cancer (CALOR) trial. [6]
Can breast cancer recur after mastectomy?
The recurrence of breast cancer after mastectomy for DCIS is uncommon, but for women who do relapse with invasive disease, the mortality rate is high. [2] While there is ongoing debate regarding the overtreatment of DCIS, there are factors associated with an increased risk of locoregional recurrence even after mastectomy; these include young age (< 40–45 years), close/positive margins (≤ 2 mm), and large multifocal disease. [3] In addition, a tumor grade of 3 has a small but significant negative impact on relapse rates, suggesting the need to optimize therapy in these patients. [4]

Is axillary radiation given?
Axillary radiation will be given regardless. If there is concern about the morbidity associated with axillary dissection, this will be addressed in a multidisciplinary discussion. It is important to highlight a common misconception that patients and family members have about bilateral mastectomies.
What is the treatment for ductal carcinoma?
Treatment of these type of tumors is usually surgical, with lumpectomy or mastectomy. In addition, doctors may prescribe adjuvant radiation therapy. Nonetheless, about 60% of infiltrative centrally necrotizing ductal carcinomas do either recur locally or metastasize to a distant site.
What is necrosis in breast cancer?
Invasive ductal cancer with Central Necrosis. “ Necrosis ” refers to the debris left behind when cells die. In the context of a suspected breast cancer tumor doctors usually consider necrosis as an indicator of a more aggressive breast carcinoma. It is quite common to see cell necrosis in mature invasive breast cancers.
What happens if you have a certain nuclear feature in a breast cancer diagnosis?
Some breast canc er researches propose that if certain features are present in an intermediate grade DCIS, such as a certain nuclear feature or the presence and degree of necrosis, then the carcinoma might proceed directly to invasive breast cancer status.
What is intermediate grade DCIS?
Intermediate grade DCIS. High grade DCIS. Invasive ductal carcinoma. But there are alternative models emerging now, suggesting that DCIS does not necessarily have to be of a high grade before transforming into an invasive breast cancer.
What happens when a breast cancer lesion is detected?
When a suspicious lesion appears on breast cancer screening then a biopsy may well follow. At this point, the pathologist may well encounter a characteristic ‘central necrosis’ pattern in the lesion.
When does central necrosis occur?
The average age of development of an infiltrative ductal carcinoma with central necrosis is hard to estimate, but generally occurs in the mid 50’s. Most infiltrative breast carcinomas with central necrosis are estrogen and progesterone receptor negative, making them more resistant to treatment.
How to determine the extent of breast cancer?
In order to determine the true extent and potential threat of the breast carcinoma, one has to perform additional biopsies and imaging studies from various locations. Also, doctors must pay very close attention to the immunohistochemical analysis of the biopsy specimen.
