Carcinoma breast ductal intraductal papillary-IDC Type: Papillary Carcinoma of the Breast

The clinical and pathological features of 77 cases of intraductal intracystic papillary carcinoma IPC of the breast are reported. It should be recognized as an intraductal carcinoma variant and distinguished from invasive papillary carcinoma. Intraductal papillary carcinoma remains a difficult diagnosis as there are four different epithelial growth patterns any of which may predominate. Low grade nuclear features occur in one third of cases, a so-called "stratified spindled cell" epithelial proliferation with bland morphology occurs in one quarter of cases, and a dimorphic population of malignant cells, which may in part be confused with myoepithelial cells, occurs in one quarter of cases. The 77 cases studied were from the year interval to

What is papillary breast cancer?

  • When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist.
  • Breast cancer is classified into different types based on how the cells look under a microscope.
  • Papillary carcinoma of the breast, also known as intraductal papillary carcinoma, is a rare type of breast cancer that accounts for only 0.
  • Management changes announced, click here.
  • Ductal carcinoma in situ DCIS is non-invasive breast cancer.

The name comes from finger-like projections, or papules , which are seen when the cells are looked at under the microscope. Many papillary tumors are benign. These are called papillomas. Even when a biopsy is negative for cancer, the pathologist often needs to look at the whole tumor under the microscope to be sure about the diagnosis.

This is why surgery to remove a papilloma is usually recommended, even if it is thought to be benign. Malignant papillary tumors are a form of breast cancer. Like other types of invasive ductal cancer, papillary breast cancer begins in the milk duct of the breast. Most of the time, papillary breast cancers include both in situ cells which have not yet spread outside of the duct and invasive cells which have begun to spread outside of the duct.

Compared to more common types of breast cancers, papillary breast cancers are less likely to involve the lymph nodes, are more responsive to treatment, and may have a better prognosis than more common types of invasive ductal cancer. Local therapy is aimed at preventing the cancer from coming back in the breast.

Local therapy includes surgery lumpectomy or mastectomy , and may include radiation. Systemic therapy is used to prevent the disease from coming back or spreading to another part of the body.

This may include endocrine hormone therapy, chemotherapy, and therapy that targets the HER2 protein. Often different types of treatment are used together to achieve the best result. Your treatment plan will be based on the features of the tumor type of cells, tumor grade, hormone receptor status, and HER2 status and the stage of the disease tumor size and node status. We know that it can be stressful to receive a diagnosis of breast cancer, and learning that you have a rare form of the disease can add to your anxiety.

For example, the report may say that DCIS was found in 3 slides. 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. The larger the area of DCIS, the more likely it is to come back recur after surgery. Doctors use information about the size of the DCIS when recommending further treatments.

Paget disease of the nipple is usually associated with DCIS or invasive carcinoma cancer in the underlying breast tissue. If Paget disease is found on needle or punch biopsy, more tissue in that area usually needs to be removed with the goal of entirely removing the area of Paget disease. Talk to your doctor about the best treatment for you. These are special tests that the pathologist sometimes uses to help make the diagnosis of DCIS.

Not all cases need these tests. Whether your report does or does not mention these tests has no bearing on the accuracy of your diagnosis.

ER and PR are special tests that the pathologist does that are important in predicting response of the DCIS to hormone therapy like tamoxifen. Results for ER and PR are reported separately and can be reported in different ways:. 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.

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. If your pathology report shows DCIS with positive margins, your doctor will talk to you about what treatment is best. These findings are less serious than DCIS, and you should talk with your doctor about what these findings may mean to your care.

All of these are terms for benign non-cancerous changes that the pathologist might see under the microscope. They are not important when seen on a biopsy where there is DCIS. Microcalcifications or calcifications are mineral deposits that can be found in both non-cancerous and cancerous breast lesions.

They can be seen both on mammograms and under the microscope. Because certain calcifications are found in areas containing cancer, their presence on a mammogram may lead to a biopsy of the area. Then, when the biopsy is done, the pathologist looks at the tissue removed to be sure that it contains calcifications. If the calcifications are there, the treating physician knows that the biopsy sampled the correct area the abnormal area with calcifications that was seen on the mammogram.

Microcalcifications and calcifications only matter because they are sometimes found in areas containing cancer. When they are found alone without worrisome changes in the breast ducts or lobules , they are not important. Molecular tests may help predict the chances of DCIS coming back recurring in the breast, but not all cases need these tests. The results should be discussed with your doctor. The results do not affect your diagnosis, although they might affect your treatment. This series of Frequently Asked Questions FAQs was developed by the Association of Directors of Anatomic and Surgical Pathology to help patients and their families better understand what their pathology report means.

Learn more about the FAQ Initiative. Understanding Your Pathology Report: Ductal Carcinoma In Situ DCIS When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. What is carcinoma? What is in-situ carcinoma or carcinoma in situ of the breast? What does it mean if my in-situ carcinoma is called ductal carcinoma in situ DCIS , intraductal carcinoma, or in-situ carcinoma with duct and lobular features?

What does it mean if my report mentions E-cadherin? What does it mean if my report describes my ductal carcinoma in situ DCIS as being cribriform, micropapillary, apocrine, comedo, with comedonecrosis, papillary, or solid? What does it mean if my ductal carcinoma in situ DCIS is described as being low grade, intermediate grade, or high grade; or nuclear grade 1, nuclear grade 2, or nuclear grade 3; or low mitotic rate, intermediate mitotic rate, or high mitotic rate?

IDC accounts for about 80 percent of invasive breast cancers. The goal of this treatment is to remove the cancer from the breast with a lumpectomy or mastectomy. The type of surgery recommended will depend on factors such as the location of the tumor, the size of the cancer and whether more than one area in the breast has been affected. For patients with ductal carcinoma, long-term systemic treatment with tamoxifen is recommended to prevent recurrence.

Medullary ductal carcinoma: This type of cancer is rare and accounts for only 3 percent to 5 percent of breast cancers. Medullary carcinoma may occur at any age, but it typically affects women in their late 40s and early 50s. Medullary carcinoma is more common in women who have a BRCA1 gene mutation. Medullary tumors are less likely to involve the lymph nodes, are more responsive to treatment, and may have a better prognosis than more common types of invasive ductal cancer.

Surgery is typically the first-line treatment for medullary ductal carcinoma. A lumpectomy or mastectomy may be performed, depending on the location of the tumor. Chemotherapy and radiation therapy may also be used. Mucinous ductal carcinoma: This type of breast cancer accounts for less than 2 percent of breast cancers. Microscopic evaluations reveal that these cancer cells are surrounded by mucus.

Like other types of invasive ductal cancer, mucinous ductal carcinoma begins in the milk duct of the breast before spreading to the tissues around the duct. Sometimes called colloid carcinoma, this cancer tends to affect women after they have gone through menopause. Surgery is typically recommended to treat mucinous ductal carcinoma. A lumpectomy or mastectomy may be performed, depending on the size and location of the tumor.

Adjuvant therapy, such as radiation therapy, hormonal therapy and chemotherapy, may also be required. Papillary ductal carcinoma: This cancer is rare, accounting for less than 1 percent of invasive breast cancers. In most cases, these types of tumors are diagnosed in older, postmenopausal women.

Under a microscope, these cells resemble tiny fingers or papules. Most papillary carcinomas are invasive and are treated like invasive ductal carcinoma. Surgery is typically the first-line treatment for papillary breast cancer. Tubular ductal carcinoma: Another rare type of IDC, this cancer makes up less than 2 percent of breast cancer diagnoses.

Like other types of invasive ductal cancer, tubular breast cancer originates in the milk duct, then spreads to tissues around the duct. Tubular ductal carcinoma cells form tube-shaped structures. Tubular ductal carcinoma is more common in women older than Treatment options for tubular ductal carcinoma depend on the aggressiveness of the cancer and its stage. Lobular carcinoma begins in the lobes or lobules glands that make breast milk. The lobules are connected to the ducts, which carry breast milk to the nipple.

Lobular carcinoma in situ LCIS : It begins in the lobules and does not typically spread through the wall of the lobules to the surrounding breast tissue or other parts of the body. While these abnormal cells seldom become invasive cancer, their presence indicates an increased risk of developing breast cancer later.

Papillary breast cancer

The clinical and pathological features of 77 cases of intraductal intracystic papillary carcinoma IPC of the breast are reported. It should be recognized as an intraductal carcinoma variant and distinguished from invasive papillary carcinoma. Intraductal papillary carcinoma remains a difficult diagnosis as there are four different epithelial growth patterns any of which may predominate.

Low grade nuclear features occur in one third of cases, a so-called "stratified spindled cell" epithelial proliferation with bland morphology occurs in one quarter of cases, and a dimorphic population of malignant cells, which may in part be confused with myoepithelial cells, occurs in one quarter of cases.

The 77 cases studied were from the year interval to The effect on prognosis of cytoarchitectural features, duct wall and stromal invasion, and associated intraductal carcinoma were evaluated. The contribution of immunohistochemistry to the diagnosis using antibodies to smooth muscle actin, S protein, and CAM 5. Three of the patients developed metastases; two were alive with tumor and one died of other causes. Six patients had local recurrence in the chest wall; one was alive without disease, two were alive with tumor, and three died of other causes.

When IPC recurred or metastasized, it did so as invasive papillary carcinoma in six of seven cases. Stromal invasion was found in 13 patients. Local recurrence developed in two of these.

Invasion was not seen in any of the three patients who developed metastases. However, this may be a function of sampling as there was an average of 5. Patients with low grade tumors had no recurrence or metastasis, and in the absence of invasion may be treated by local excision. Patients with higher grade tumors have an increased risk of recurrence and metastasis.
