What is poorly differentiated adenocarcinoma?

Poorly differentiated adenocarcinoma is a serious condition that can threaten a patient's life. Patients with this type of cancer may have a rapidly growing tumor that is difficult to completely remove. Adenocarcinoma can attack many different systems, including internal organs, breasts, lymph nodes, and skin. The prognosis for this type of cancer depends largely on the system in which the cancer is first found, as well as the differentiation of the cancer cells.

Doctors will take a biopsy of a patient's tumor to determine how differentiated the cancer cells are. Looking at the cells under a microscope will reveal whether they appear similar to healthy cells or whether they have many mutations and poorly developed organelles. Cells that develop with many mutations and those that do not mature properly are often said to be poorly differentiated adenocarcinoma cells, because the various parts of these cells are not clearly defined.

Patients with poorly differentiated adenocarcinoma are often at risk for cancer. These cells divide rapidly and do not respond to proximity triggers that prevent normal cells from dividing. Cancer cells also do not die naturally, allowing the cancerous tumor to grow rapidly. Poorly differentiated adenocarcinoma grows faster than other types of adenocarcinoma, which means that it can quickly take over organs and move through the patient's body, spreading to nearby systems.

Aggressive treatment is needed to increase a patient's chance of surviving poorly differentiated adenocarcinoma. These cells can take over quickly, which means time is of the essence when developing a treatment plan for a patient's cancer. Chemotherapy, surgery, radiation, and other treatments may be used to try to control the cancer. Alternative treatments may be used along with standard treatments because they can increase the patient's chance of survival.

Although poorly differentiated adenocarcinoma is often indicative of a severe form of cancer, there are many factors other than cell differentiation that affect a patient's prognosis. This type of cancer can occur in many different parts of the body, and the affected organ has a strong influence on the probability that the patient will successfully fight the cancer. Depending on the area in which the cancer is present, the diagnosis of poorly differentiated adenocarcinoma can be divided into various levels of poor differentiation.
