cancer grading manual

After an introduction on the history and basic tenets of tumor grading, subsequent chapters focus on specific organ systems. In each case, the most widely used system for grading common tumors is presented and discussed. Throughout, careful attention is paid to the principles of microscopic tumor grading, ancillary methods to improve grading, and the latest techniques used in evaluating tumors and formulating prognosis. Since the first edition, all chapters have been updated to reflect revisions in the clinical practice of pathology and to explain the role of novel immunohistochemistry and molecular biology techniques. In addition, a new chapter is devoted to the latest trends in cancer grading, and further illustrations have been included.

It discusses the history and basic tenets of tumor grading; principles of microscopic grading of tumors; ancillary methods currently used to improve tumor grading; and new techniques used in evaluating tumors and formulating prognosis. It is designed to be a practice-oriented, concise and well-illustrated resource for diagnostic surgical pathologists and pathology residents. There are 208 color illustrations. Only valid for books with an ebook version. For cases diagnosed 2018 and later, see the NAACCR 2018 Implementation (PDF). Codes 5, 6, 7, and 8 are used only for hematopoietic and lymphoid neoplasms. Code 9 indicates cell type not determined, not stated, or not applicable. For these cancers, the grade is a measurement of how closely the tumor cells resemble the parent tissue (organ of origin). Well-differentiated tumor cells closely resemble the tissue from the organ of origin. Poorly differentiated and undifferentiated tumor cells are disorganized and abnormal looking; they bear little (poorly differentiated) or no (undifferentiated) resemblance to the tissue from the organ of origin. Some grading systems use only pattern, for example Gleason grading in prostate.http://www.generale-bureautique.fr/gdb/files/bt-duet-200-plus-manual.xml

Others use only a nuclear grade (usually size, amount of chromatin, degree of irregularity, and mitotic activity). Fuhrman’s grade for kidney is based only on nuclear features. Most systems use a combination of pattern and cytologic and nuclear features; for example Nottingham’s for breast combines numbers for pattern, nuclear size and shape, and mitotic activity. The information from this data item is useful for determining prognosis and treatment. The four-grade system describes the tumor as Therefore, it is important to code grade based on information prior to neoadjuvant therapy even if grade is unknown. In the rare instance that tumor tissue extends contiguously to an adjacent site and tissue from the primary site is not available, code grade from the contiguous site. Do NOT code grade for dysplasia such as high grade dysplasia. Code the highest grade even if it is only a focus. Code grade in the following priority order using the first applicable system: See Special Grade System Rules section below for details on how to use this information to code grade. If your registry does not collect this SSF, use the description in the table below to determine grade. If you collect this SSF, codes 030-130 could be automatically converted into the grade field. Examples: different scores may be reported on multiple pathology reports for the same primary cancer; different scores may be reported for multiple tumors assigned to the same primary cancer. Do not use for kidney renal pelvis. If your registry does not collect this SSF, use the description in the table to determine grade. If you collect this SSF, the information could be automatically converted into the grade field if it is coded 010-040. Fuhrman nuclear grade is a four-grade system based on nuclear diameter and shape, the prominence of nucleoli, and the presence of chromatin clumping in the highest grade. If your registry does not collect this SSF, use the description in the table to determine grade.

If you collect this SSF, the information could be automatically converted into the grade field if it is coded 010-200. The grading system of the French Federation of Cancer Centers Sarcoma Group (FNCLCC) is the preferred system. Use a known value over an unknown value. Exclude results from tests performed after neoadjuvant therapy began. Use the table below to determine grade even if your registry does not collect these SSFs. If you collect these SSFs, the information could be converted into the grade field automatically. Gleason grading for prostate primaries is based on a 5-component system (5 histologic patterns). Prostatic cancer generally shows two main histologic patterns. The primary pattern, the pattern occupying greater than 50% of the cancer, is usually indicated by the first number of the Gleason grade, and the secondary pattern is usually indicated by the second number. These two numbers are added together to create a pattern score, ranging from 2 to 10. If there are two numbers, assume that they refer to two patterns (the first number being the primary pattern and the second number the secondary pattern), and sum them to obtain the score. If only one number is given on a particular test and it is less than or equal to 5 and not specified as a score, do not use the information because it could refer to either a score or a grade. If only one number is given and it is greater than 5, assume that it is a score and use it. If the pathology report specifies a specific number out of a total of 10, the first number given is the score. The Gleason score would be 3. The original grade field would NOT be changed, but for analyses this recode could be based on the CS SSFs and the original grade code.

A diagnosis is made when cells are examined through a microscope. There are several ways biopsy samples can be obtained. \r\n \r\n \r\n \r\n\r\n Needle biopsy is used when a lesion or tumor can be felt or identified on imaging studies. During the procedure, a thin hollow needle is inserted into the lesion and guided by x-ray or ultrasound equipment. A small sample of the tissue is removed for analysis. When suction is applied to the needle to obtain a sample, the procedure is called an aspiration biopsy. \r\n \r\n \r\n \r\n\r\n An incisional biopsy is performed when abnormal tissue is not directly accessible by less invasive methods, or when a larger specimen is desired. During this surgical procedure, local anesthetic is administered and a section or portion of a tumor is removed. Sutures are required to close the skin following an incisional biopsy. These biopsies are usually performed as an outpatient procedure. \r\n \r\n \r\n \r\n\r\n During an excisional biopsy, local anesthetic is administered and the surgeon cuts into or through the skin to remove the entire tumor, as well as some of the surrounding normal tissue. In some cases, removal of all abnormal tissue at a site completes the need for diagnosis and treatment. Following tissue removal, the incision is closed with sutures. \r\n \r\n \r\n \r\n\r\n Frozen section is used when a biopsy specimen needs to be obtained and analyzed immediately during surgery.

Occasionally, x-rays obtained for other reasons, such as an injury, show abnormalities that might be cancer. Confirmation that cancer is present requires other tests (termed diagnostic tests). Staging is a way of describing how advanced the cancer has become, including such criteria as how big it is and whether it has spread to neighboring tissues or more distantly to lymph nodes or other organs. Screening tests usually are not definitive. Results are confirmed or disproved with further examinations and tests. Diagnostic tests are done once a doctor suspects that a person has cancer. Screening test results can be falsely positive or falsely negative: False-negative results can lull people into a false sense of security. For these reasons, there are only a small number of screening tests that are considered reliable enough for doctors to use routinely. The American Cancer Society has provided cancer screening guidelines that are widely used. Other groups have also developed screening guidelines. Sometimes recommendations vary among different groups, depending on how the groups' experts weigh the relative strength and importance of available scientific evidence. Doctors may feel the thyroid gland or lymph nodes to detect growths. Dentists examine the mouth and tongue to look for signs of mouth cancers. Both screening tests have been successful in reducing the death rates from these cancers in certain age groups. PSA levels are often high in men with prostate cancer, but levels also are elevated in men with noncancerous (benign) enlargement of the prostate. As such, the main drawback to its use as a screening test is the large number of false-positive results, which generally lead to more invasive tests such as a prostate biopsy. And doctors are now realizing that not all prostate cancers found on biopsy will go on to cause problems.

Whether the PSA test should be used routinely to screen for prostate cancer is unresolved, with varying recommendations from different groups. Men over 50 should discuss the PSA test with their doctor. Finding occult blood in the stool is an indication that something is wrong somewhere in the digestive tract. The problem may be cancer, although many other disorders, such as ulcers, hemorrhoids, diverticulosis (small pouches in the colon wall), and abnormal blood vessels in the intestinal walls, can also cause small amounts of blood to leak into the stool. In addition, taking an aspirin or another nonsteroidal anti-inflammatory drug (NSAID) or even eating red meat can temporarily cause a positive test result. Positive results on some older tests can occasionally be caused by consuming certain raw fruits and vegetables (turnips, cauliflower, broccoli, melons, radishes, and parsnips). Newer screening tests for occult blood use a different technique and are much less susceptible to such errors. Outpatient procedures such as sigmoidoscopy, colonoscopy, and a special type of computed tomography (CT) of the colon (CT colonography) are also often used for colon cancer screening. However, except possibly for testicular cancer, home screening with self-examinations has not been proved to be effective in identifying cancer, so even if people do examinations at home it is important to also follow recommendations for screening tests. An abnormal result should prompt a visit to the doctor for confirmation. It was first thought that measuring levels of these markers would be an excellent way to screen asymptomatic people for cancer. However, tumor markers are often present to some extent in the blood of people who do not have cancer. Finding a tumor marker does not necessarily mean a person has cancer, and tumor markers have a very limited role in cancer screening.

For people with a higher risk, such as those with a strong family history of certain cancers or those who have had a previous cancer, screening may be recommended more frequently or to start at a younger age. Screening tests other than those listed here may also be recommended. Furthermore, other organizations, such as the U.S. Preventive Services Task Force, may have slightly different recommendations. A person's physician can help the person decide when to begin screening and which tests should be used. For example, a person with chronic cough and weight loss might have a chest x-ray. A person with recurrent headaches and trouble seeing might have brain CT or magnetic resonance imaging (MRI). Although these tests can show the presence, location, and size of an abnormal mass, they cannot confirm that cancer is the cause. Usually, the sample must be a piece of tissue, although sometimes examination of the blood is adequate (such as in leukemia). Obtaining a tissue sample is termed a biopsy. Such tests are commonly done without the need for an overnight hospital stay (outpatient procedure). Doctors often use ultrasonography or CT to guide the needle to the right location. Because biopsies can be painful, the person is usually given a local anesthetic to numb the area. In people who have been diagnosed with certain types of cancer, tumor markers may be useful to monitor the effectiveness of treatment and to detect possible recurrence of the cancer. For some cancers, the level of a tumor marker drops after treatment and increases if the cancer recurs. These markers are found by examining tissue from a biopsy sample. HER2 and EGFR are examples of tumor markers found on tumor cells. In addition, elevated AFP is often found in people with certain cancers of the ovary or testis. Blood levels are elevated in medullary thyroid cancer. Blood levels may also be elevated in patients with other cancers or noncancerous inflammatory conditions.

Men with an elevated PSA level should be evaluated further by a doctor. In families with inherited medullary thyroid cancer, a rare condition, levels of calcitonin in the blood also may be a useful screening test. People with cancer sometimes become impatient and anxious during staging tests, wishing for a prompt start of treatment. However, staging allows doctors to determine the most appropriate treatment as well as help to determine prognosis. The choice of staging test(s) depends on the type of cancer. CT is used to detect cancer in many parts of the body, including the brain and lungs and parts of the abdomen, including the adrenal glands, lymph nodes, liver, and spleen. MRI is of particular value in detecting cancers of the brain, bones, and spinal cord. For example, during a laparotomy (an abdominal operation) to remove colon cancer, a surgeon removes nearby lymph nodes to check for spread of the cancer. During surgery for breast cancer, the surgeon biopsies or removes a lymph node located in the armpit (the first lymph nodes to which cancer is likely to spread, also called a sentinel lymph node) to determine whether the breast cancer has spread there. Evidence of spread, along with features of the primary tumor, helps the doctor determine whether further treatment is needed. When the doctor uses results of a surgical procedure or additional biopsies, the stage is referred to as pathologic or surgical. The clinical and pathologic (surgical) stages may differ. A cancer's grade can help doctors determine prognosis. Grade is determined by examining the tissue specimen obtained during a biopsy. Grade is based on the degree of abnormality of the appearance of cancer cells on microscopic examination. More abnormal appearing cells are more aggressive. For many cancers, grading scales have been developed. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.

This editorial summarizes the background of the current revision and outlines the major issues revised. Most notable are the marked increase in the use of international datasets for more highly evidenced-based changes in staging, and the enhanced use of nonanatomic prognostic factors in defining the stage grouping.

The future of cancer staging lies in the use of enhanced registry data standards to support personalization of cancer care through cancer outcome prediction models and nomograms. The intent was to better understand the clinical behavior of specific cancers, determine prognosis, and help physicians compare outcomes of similar groups of patients. In 1987, it became accepted worldwide as the anatomic staging system for most solid tumors. 1 The latest, AJCC Cancer Staging Manual, Eighth Edition, 2 which became effective on January 1, 2018, is the most ambitious one yet. It signifies a dramatic departure from previous staging classifications to keep pace with the rapid advances in knowledge regarding the biologic and molecular factors that determine the clinical course of cancer. Factors such as tumor grade, hormone receptor, and oncogene expression, as well as multigene panel recurrence scores are now integrated with anatomic definitions. You have to include biomarkers to provide patients with more precise individual prognostication,” said Frederick L. Greene, MD, FACS, Medical Director of Cancer Data Services at the Levine Cancer Institute, and co-editor of the seventh and eighth editions of the manual. “In the latest edition, in addition to including prognostic biologic and molecular factors for breast cancer, we have included that information for gastrointestinal cancer, melanoma, and other tumor types as well.” In addition, to ensure that the information contained in the manual is always current, AJCC is planning to make periodic updates to the manual available on its website, cancerstaging.org.

Meaning AJCC 8th edition (AJCC 8) has not been evaluated. Objectives Design, Setting, and Participants. The study was carried out at a single academic tertiary care center in Boston, Massachusetts. Main Outcomes and Measures The AJCC 8 T2 and T3 comprised 23% of cases and had statistically indistinguishable outcomes. The BWH had higher specificity (93%) and positive predictive value (30%) for identifying cases at risk for metastasis or death. Conclusions and Relevance The BWH identifies the same number of poor outcomes in a 9% subset of HNCSCCs, thus minimizing inappropriate upstaging of low-risk disease. The American Joint Committee on Cancer (AJCC) Tumor Classification, 7th edition (AJCC 7) for CSCC introduced several prognostic factors besides tumor diameter. 5, 6 However, AJCC staging has suffered from an inability to validate and refine the system via population-based data because CSCC is excluded from the Surveillance, Epidemiology, and End Results Program.

Another recent study found that AJCC 7, AJCC 8, and BWH tumor classifications did not identify CSCC tumors at risk for metastasis. 11 However, information on the primary tumor was unavailable in many metastatic cases, prohibiting accurate T staging. Data used in the present study included the subset of CSCCs located on the head and neck (HNCSCC) from a previously published Brigham and Women’s CSCC cohort study. 12 Data collection procedures have been previously published. 6, 12 In brief, patients with CSCC diagnosed at BWH from January 1, 2000, through December 31, 2009, were identified via a department of pathology electronic database. Pathology reports were reviewed and noncutaneous SCC, in situ CSCC, and recurrent CSCC were excluded. Only tumors located on the head and neck were included in the present analysis because AJCC 8 staging system is specific for HNCSCC. Tumors were classified according to BWH and AJCC 8 tumor classifications. When risk factors were not reported on the pathology report or Mohs operative note, they were assumed to be absent. Pathologists and Mohs surgeons at BWH routinely report histologic differentiation, the presence of perineural invasion (PNI), and tumor invasion beyond the dermis. Thus, if there was no mention of depth of invasion, PNI, or differentiation, the tumor was assumed to be well differentiated, less than 6 mm, and confined to fat with no PNI. Histologic review was performed for cases with reported PNI to ensure there was tumor present in the nerve sheath and to record millimeter caliber of involved nerves. Death from non-CSCC causes was considered a competing event. Cox proportional hazards regression models were used for overall survival (OS) owing to the absence of competing risks for this outcome. Overall survival was calculated by patient rather than for each individual tumor. Survival time for each end point of interest was calculated from the date of CSCC tumor diagnosis to date of outcome occurrence.

For tumors without any poor outcome, survival time was censored on the date of death or medical record review if patient was alive at the time of data collection. The proportional hazards assumption was checked using Schoenfeld residuals. Cumulative incidence function curves for LR, NM, and DSD, and Kaplan-Meier survival curves for OS were generated by BWH tumor classification for HNCSCC. The curves for AJCC 8 for this cohort have previously been published, but are displayed in the Figure to facilitate comparison with BWH. 10 Performance of tumor classification system was assessed in terms of homogeneity (outcomes are similar within tumor class), monotonicity (outcomes worsen with increasing tumor class), and distinctiveness (outcomes differ between tumor class). To evaluate tumor classification homogeneity and monotonicity, the proportion of poor outcomes occurring in low and high tumor classes was compared using the McNemar test. To evaluate tumor classification distinctiveness, the 10-year cumulative incidences with corresponding 95% confidence intervals (CI) and C statistic were compared by tumor classification system by outcome. Discrimination was measured by the C statistic (or concordance statistic), which is a measure of the area under the receiver operating characteristic (ROC) curve and is used to determine distinctiveness. The C statistic in the present study is the probability a tumor with a poor outcome had a higher chance of being high tumor class in the modeled data than a randomly chosen patient without the outcome in the same model. A value of 1.0 indicates the model (in this case, high vs low tumor class) has perfect distinctiveness whereas a value of 0.5 indicates the model has no distinctiveness. The Gray test was used for statistical comparisons of cumulative incidence estimates and log-rank test was used to compare cumulative survival estimates.
