Tumor board review is an approach to planning cancer treatment in which a team of doctors from different specialties work together to reach an opinion. In addition, pathologists participate in tumor board review. Most accredited labs require a second pathologist to confirm the diagnosis for all cancers. Typically, pathologists share all cancer diagnoses with their associates, especially when a patient has a cancer that is difficult to diagnose or treat. Pathologists seek multiple opinions, and patients can, too. At other times and only if the patient gives permission, biopsy samples may be used in research to help discover new treatments and targeted therapies. We also may review the samples again if new treatments based on a tumor’s genetics become available. By looking at the sample again, we can find out if the original primary tumor has come back or if it is a new cancer. Some states may require even longer storage periods.īy saving biopsy tissue for a long time, the pathologist may review the primary tumor if a patient has that cancer come back or spread in the future. Paraffin blocks (material where tissues are usually processed) are retained for at least 10 years. Other types of stained tissue slides are typically kept for 10 years or more. For example, cytology slides, like Pap tests, are usually stored for at least 5 years. Biopsy samples are safely stored and secured to help manage future treatment.įederal law requires laboratories to safely store specimens for a set amount of time. As we identify more precise characteristics of cancer from the biopsy sample, we can identify a growing number of patients who may benefit from new, more effective targeted therapies. For example, in breast cancer, pathologists use the biopsy sample to identify hormone receptors such as estrogen and progesterone receptors (ER and PR) and human epidermal growth factor receptor (HER2). These can include genetic changes that could guide treatment options or predict your chance of recovery. Your pathologist will also make sure that biopsy samples are used to identify other factors affecting your treatment and recovery. This is really valuable in treating cancer that has spread from another part of the body, called metastasis. But we can also use the samples to perform additional tests, such as immunostains, which can identify where a tumor started. Samples allow us to make a correct diagnosis. Pathologists are the caretakers of tissue samples and must exercise good judgment with them. Pathologists make sure biopsy tissue is used effectively to determine an accurate diagnosis. But be assured that the pathologist is using his or her specialized expertise to make sure you get an accurate diagnosis. It can be agonizing to wait for biopsy results. This process takes an additional 24 to 96 hours, depending on the complexity of the cancer. If your pathologist suspects certain types of cancer, such as lymphoma, he or she might need to perform additional testing to determine the subtype. Depending on the type of evaluation needed, the next steps might take a few hours or several days. Tissue processing takes several steps, but it starts with making sure the correct test was done on the correct patient. Typically, the biopsy sample is then saved in a special type of preservative and sent to the pathology lab for processing. These procedures are usually fairly quick and might take 15 to 30 minutes to perform, depending on the part of the body being biopsied. These include shave biopsies, punch biopsies, Pap tests and cervical biopsies, and even some fine needle aspiration biopsies (FNABs) for the thyroid or lymph nodes. Some biopsies can be performed in a doctor’s office or an outpatient clinic. The time required for biopsy results will vary. In these cases, the pathologist will ask your doctor to repeat the biopsy, so the pathologist can make a conclusive and accurate diagnosis. Other times, the pathologist can see that the sample was not taken from the correct area. Sometimes a biopsy sample might not be big enough to evaluate. They use powerful microscopes to evaluate the cells within each tissue sample. Pathologists are trained to evaluate many different types of tissue. Here are 5 things this pathologist wants every patient to know about biopsy. This is the doctor who analyzes the sample of tissue removed during a biopsy to make the correct diagnosis. There is a member of your health care team who plays a vital role in your diagnosis and cancer care who you may never meet face to face: the pathologist. Aziza Nassar, MD, FCAP, is Professor of Pathology and Director of Cytopathology at the Mayo Clinic in Jacksonville, FL.
