what is the current recommended treatment for metaplastic breast cancer?

I think you mean metastatic breast cancer. Metastatic breast cancer means the cancer has spread from the breast to another area of the body such as lymph nodes, lungs, bones, liver or brain.

 The treatments options will include surgery, chemotherapy, radiation and hormone therapy. Which of these options that are used will depend on the characteristics of the cancer cell receptors. For example if the cancer cells have estrogen receptors the patient has a better prognosis because they may benefit from both chemotherapy and hormonal therapy.

 

 

Metaplastic breast cancer is a distinct entity, very rare type of breast cancer that has worse prognosis than "regular" breast cancer. Because it is rare (< 1%) there is no consensus on what is the best treatment, so same principles of therapy for other breast cancers are applied. Metaplastic breast cancer is frequently estrogen receptor negative so chemotherapy is usualy necessary.
