The Pathologist’s Report of Breast Cancer

By this time you’ve received a diagnosis based about the biopsy findings. You know whether or not you’ve tumor. Your diagnosis was made by the pathologist-the only member of your diagnostic team whom you most likely won’t meet, include information on regardless of whether or not cells are present, and the character from the cells which are observed under the microscope. A surgical pathology report might be within the form of the template or freely dictated, but either way it ought to contain certain information. Don’t just study the summary of the findings on the end from the report.

Study and understand the body from the record. Look on the sample surgical pathology record at the end of this chapter. Note the separation of gross findings from microscopic findings. Although they’re different, both are important towards the final diagnosis. The “gross pathology” may be dictated by a different pathologist from the one who signs the report, because the gross pathology is done the day the specimen arrives in the pathology laboratory; the tissue isn’t study until it has been examined under the microscope by the pathologist who dictates the microscopic findings. The final surgical pathology report may not be typed and signed until days later.

The essential information you should glean from the gross pathology is the size, place, and character from the specimen muscle as a entire, and the size, place, and character from the tumor (if there is any) that may be contained inside it. Don’t confuse the two. The bigger dimensions of the specimen as a entire aren’t the dimensions from the cancer. The size from the cancer has major implications for the “stage” from the tumor. If tumor is diagnosed within the specimen, the additional description of the muscle, as set forth in the gross pathology, becomes essential, such as the place of the cancer within the specimen as aentire. For example, a pathologist often can make the diagnosis of inflammatory breast cancer when he or she sees, below the microscope, cancer cells in the lymphatic ducts of the skin-the “dermal lymphatics.”

When the tumor is located on the edge from the specimen and is cut through, a reexcision will be essential. The gross pathology has told the whole story. The microscopic pathology to come will simply confirm that the margin is good. The color and also the consistency of the tumor inside the specimen are also relevant, in that they might characterize the tumor. After dictating his or her findings, the pathologist who carries out the gross pathology will cut some of the tissue into small pieces and put them into “cassettes,” porous holders of the fragments. The cassettes are submerged in a fluid that preserves the tissue.

Please note that the pathologist cannot examine every cell in a core needle specimen, or within the bigger specimen of an open biopsy. He or she might “bread loaf” the tissue by cutting it into slices like a loaf of bread and putting representative sections into cassettes. The remainder of the specimen is retained in jars containing preserving liquid, so that if there are any questions regarding the pathology, additional muscle can be examined. Legally, the pathology department should keep the preserved tissue for a specified period; nothing should be thrown away at the time of the procedure. Right after an appropriate time, laboratory technicians prepare the preserved muscle further for the pathologist who will carry out the microscopic examination.

They place very thin sections from the tissue on glass microscope slides, stain them appropriately, and cover them. The pathologist reads the slides below the microscope and dictates the “microscopic examination” portion from the record. The concluding summary gives the gist of the gross and microscopic findings. The most common breast area cancer is called adenocarcinoma. The term is truly a composite: “adeno” describes the tissue of origin of the cancer; “carcinoma” is really a fancy term for cancer. Thus, an adenocarcinoma is a tumor of glandular origin. And a breast area adenocarcinoma is really a breast area cancer of glandular origin.

The specific muscle where the breast area cancer has originated is either within the duct system from the breast (when it’s recognized as ductal adenocarcinoma or, a lot more commonly, ductal carcinoma) or in the lobules (the part of the breast system exactly where the milk is produced). Lobular carcinomas, when invasive, possess a life expectancy similar to that of invasive ductal carcinomas. Although they might have different characteristics, the two are subjected towards the same treatment. (You should be aware that invasive lobular carcinomas frequently are not visualized on screening mammograms simply because, it’s believed, their outside edges have more tendrils and aren’t distinct.)

Both ductal and lobular carcinomas are treated differently when they’re noninvasive than when they’re invasive. A non invasive ductal carcinoma (otherwise known being a DCIS, an acronym for ductal carcinoma in situ) includes a different treatment path from that of the lobular carcinoma in situ, LCIS. The record dictated from the pathologist is typed and submitted to him or her for approval and signature. Finally, it is conveyed to you. You are able to see why it takes several days to issue the pathology record, and a number of a lot more days until you get the results. Your physician may wish to shorten the time involved by phoning the pathologist and obtaining an oral record.

But should you then get the report from your physician, who did not see the muscle below the microscope, it is certainly feasible for error to creep into the transmission. Whenever you receive the formal record, study all of it, not just the summary. If you do not understand the details, ask your doctor to explain them. Pathologists ought to know all concerning the tissue they’re handling, such as the “natural history” (untreated history) from the tumor. The report will contain the answers to three big questions: Do you have cancer? If so, what kind is it? And particularly, is it invasive or noninvasive? The pathologist’s answers will have profound consequences for your remedy. If the margin is positive, the pathologist should be able to say how good it’s.

As you can see from Figure 6, the margin could be “grossly” positive (many, many cancer cells are there) or “diffusely” good (only a relatively few cells can be observed). Obviously, when the yolk is off center, at the edge from the white of the egg, and is cut via, the margin will be called grossly positive. Actually, if the tumor has been cut through, a big number of cancer cells will remain in the tumor bed (the remaining muscle in you). Even though it is essential for the team to know when the margin is grossly or diffusely good, the bottom line for you is that if the margin is known as positive, additional surgery-a reexcision of the margin of the tumor bed-must be considered. If the pathologist’s report right after your biopsy describes cells in the lymphatics of the skin, you possess a diagnosis of inflammatory breast cancer. If that specialized cancer is treated like plain old breast area cancer (POBC), the outcome could be disastrous.

Any suspicion of inflammatory breast area tumor must be followed up, with a second opinion from an additional pathologist or oncologist if necessary. Unlike the treatment for POBC (surgical treatment, chemotherapy or hormonal therapy, and radiation), the sequence of treatment for inflammatory breast cancer is chemotherapy or hormonal therapy first, then surgery, and then radiation. If inflammatory breast tumor is treated having a mastectomy on the outset, the cancer cells within the dermal lymphatics are cut through on the time from the initial surgery and can spread all over the chest wall. Soon thereafter, tumor nodules can appear on the chest wall en curasse-covering the entire chest wall. This progression spells disaster for the patient.

If chemotherapy or hormonal therapy can render the dermal lymphatics free of tumor, you will find two outcomes. First, the peau d’orange appearance from the breast area skin can disappear and, second, surgical treatment could be carried out safely. On the same time, the systemic treatment affects the big central mass of tumor and makes it much smaller, and therefore surgically amenable to remedy. The pathologist has still another role: to give the tumor a pathologic stage. This last and crucial staging includes a substantial bearing on your future. The pathologist in no way creates formal treatment recommendations, because the pathologist isn’t a treating doctor.

The treatment team makes treatment recommendations. Only the patient makes remedy decisions. The pathologist may possess a strong opinion about what the treatment ought to be, but it isn’t stated in the pathology report or in any formal setting in which the pathologist participates (for example, at a tumor board-about which you will hear a lot more in a moment). If the disease or tumor diagnosed is rare, the pathologist might comment appropriately within the pathology record. Patients are usually pleased to have their case presented to a tumor board. They imagine that physicians with different specialties will very carefully evaluate their case. The operative word is very carefully. Optimally, the slides should be presented by the pathologist assigned to the tumor board as well as by the presenting doctor. Presumably the pathologist has had time to review the slides beforehand.

Similarly, the x-rays should be evaluated prior towards the tumor board meeting and presented from the assigned radiologist. If the slides and x-rays are carefully reviewed and presented, the role from the tumor board can be extremely meaningful. Regularly, however, the films or slides aren’t present. Or the pathologist or radiologist is absent. Or the specialists have not had enough time to review the slides or films. Frequently the attending doctor is seeing the slides for the first time. In such hit-or-miss circumstances, the board’s recommendations might not be really thoughtful or they may be biased in favor from the presenting doctor.

Even if the tumor board is nicely organized and nicely prepared, the situation frequently is presented rather quickly. The pathologist, the radiologist, and also the physicians on the board have little opportunity to believe about the situation, the patient isn’t seen, and the recommendations might be tainted from the presentation. There is no substitute for seeing and examining the patient and taking sufficient time to believe about the situation right after reviewing all the records, films, and slides. Tumor board recommendations are just that-recommendations. They should never be accepted as definitive treatment decisions. Your remedy team is responsible for explaining your treatment choices to you, and only you are able to decide what remedy you’ll have.
