ductal carcinoma

Bottom Line: Six factors were associated with invasive recurrence of breast cancer after a diagnosis of ductal carcinoma in situ (DCIS), according to data from a meta-analysis.

Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

For patients diagnosed with breast cancer, determining whether cancer cells have spread to the axillary lymph nodes of the armpit is important for guiding treatment decisions. It has been debated whether axillary ultrasound imaging is equally sensitive for detecting axillary metastatic lymph nodes in different subtypes of breast cancer.

Ductal carcinoma in situ is a noninvasive form of breast cancer. Although the condition is not life-threatening in itself, it may increase the chances of developing an invasive form of breast cancer later in life. However, a new study suggests that women who have been treated for ductal carcinoma in situ continue to live as long as other women.

New research suggests that DCIS patients are expected to live as long as the general female population.

Vaccinating women against the human papillomavirus (HPV) may prevent some forms of breast cancer and save tens of thousands of lives each year, new Australian research suggests.

Using genetic probes, researchers at the University of New South Wales tested cancerous breast cells and found several strains of HPVs known to have a high risk of initiating cancer of the cervix. HPV has a causal role in 90-95 per cent of cervical cancers.

Additional tests will be done on the tumor tissue to gather more information about how the cancer is likely to behave and what treatments will be most effective. Examples include:

invasive ductal carcinoma (IDC), sometimes called infiltrating ductal carcinoma, is the most common type of breast cancer. About 80% of all breast cancers are invasive ductal carcinomas.

Diagnosing invasive ductal carcinoma usually involves a combination of procedures, including a physical examination and imaging tests.

Standard treatment options for DCIS include:

Staging is the process used to figure out how far invasive ductal carcinoma may have spread from its original location. The stage of the cancer is based on three pieces of information:

  • the size of the tumor
  • whether the cancer has spread to any lymph nodes, and if so, how many
  • whether the cancer has spread to other parts of the body

Invasive ductal carcinoma is described on a scale from stage I (the earliest stage) through stage IV (the most advanced stage).
