Prostate pathology-Prostate Pathology

If you have been diagnosed with prostate cancer it is important to understand as much as you can about your condition. Because every prostate cancer is different, knowledge about the underlying biology of your tumor may help personalize your treatment plan. Your physician will perform several tests on your tumor tissue to provide specific information about your cancer. Your pathology report is one of the resources containing information about your tumor. This report will help guide your healthcare team in recommending an appropriate plan for you.

Return to the tutorial menu. The male prostate gland is located below the bladder. The seminal vesicles are located posterior to the prostate. The urethra exits from the bladder and traverses the prostate before exiting to the penile urethra.

The normal prostate is composed of glands and stroma. The glands are seen in cross section to be rounded to irregularly branching. These glands represent the terminal tubular portions of long tubuloalveolar glands that radiate from the urethra. The glands are lined by two cell layers: an outer low cuboidal layer and an inner layer of tall columnar mucin-secreting epithelium. These cells project inward as papillary projections. The fibromuscular stroma between the glands accounts for about half of the volume of the prostate.

The glands are normally separated by stroma. The prostate is surrounded by a thin layer of connective tissue that merges with surrounding soft tissues, including nerves. There is no distinct capsule. Causative agents include bacterial organisms similar to those causing urinary tract infections, as well as Neisseria gonorrheae.

A related complication of prostatic abscess is uncommon. The edema and slight enlargement of the prostate with acute inflammation may cause acute rectal, lower back, or perineal pain along with fever. There can be dysuria. The prostate is enlarged and tender. Urine culture may be done, but prostatic massage is contraindicated. Microscopically, the glands are filled with neutrophils, and the intervening stroma may also contain a few neutrophils, explaining the presence of neutrophils on urine microscopic examination..

There can be intermittent urinary frequency and dysuria. The prostate may not be enlarged. Prostatic massage may increase the yield of urine culture. Routine cultures, however, do not identify one common organism: Ureaplasma urealyticum. No organism can be identified as a causative agent. Symptoms of dysuria along with low grade pelvic pain or low back pain may be present.

Microscopically, lymphocytes, plasma cells, and macrophages appear in the prostatic stroma. Potts, Nodular prostatic hyperplasia also termed benign prostatic hyperplasia, or BPH is a common condition as men age. Perhaps a fourth of men have some degree of hyperplasia by the fifth decade of life.

Bushman, The mechanism for hyperplasia may be related to accumulation of dihydrotestosterone in the prostate, which then binds to nuclear hormone receptors which then trigger growth.

The effect of drugs which act to inhibit the enzyme 5-alpha reductase, which converts testosterone to dihydrotestosterone within cells. This blocks the growth-promoting androgenic effect and diminishes prostatic enlargement.

Such drugs include finasteride and episteride. Drug therapy must be continued to remain effective. Another class of drugs used to treat BPH are the alpha 1-adrenoreceptors, including prazosin, alfuzosin, indoramin, terazosin, doxazosin, and tamsulosin.

These alpha adrenergic blockers lead to relaxation of smooth muscle in prostate and help to relieve obstruction. Auffenberg et al, Hyperplasia begins in the region of the veru-montanum, in the inner zone of the prostate, and extends to involve lateral lobes.

This enlargement impinges upon the prostatic urethra, leading to the difficulty on urination with hesitency that is typical for this condition. Dysuria, dribbling, and nocturia are also frequent. The urinary tract obstruction leads to urinary retention and risk for infection. In severe, prolonged cases, hydroureter with hydronephrosis and renal failure can ensue. Wasserman, Microscopically, nodular prostatic hyperplasia consists of nodules of glands and intervening stroma.

Nodular hyperplasia is NOT a precursor to carcinoma. Homma et al, AAH is a localized proliferation of small acini within the prostate. Such proliferations may be confused with carcinoma, but the glands with AAH still have a fragmented basal layer. AAH can be difficult to distinguish from hyperplasia. There is no clear association between the presence of AAH and the development of prostatic adenocarcinoma. Helpap et al, Prostatic intraepithelial neoplasia PIN , which is dysplasia of the epithelium lining prostate glands, is a probable precursor of prostatic carcinoma.

It can be divided into low grade and high grade PIN. Low grade PIN may be found even in men in middle age. The acini are usually medium-sized to large, with rounded borders. The partial involvement of an acinus is a helpful feature to distinguish PIN from adenocarcinoma. PIN is characterized histologically by progressive basal cell alyer disruption, loss of markers of secretory differentiation, nuclear and nucleolar abnormalities, increasing proliferative potential, increasing microvessel density, variation in DNA content, and allelic loss.

Unlike adenocarcinoma, with which it may coexist, glands with PIN retain an intact or fragmented basal cell layer. Ayala and Ro, Low grade PIN has epithelial cells that are crowded and irregularly spaced, with nuclei that are hyperchromatic and pleomorphic, with small nucleoli.

Immunohistochemical staining with antibody to low molecular weight keratin can help to identify the fragmented basal cell layer. Anti-androgenic drug therapy may cause regression of PIN. The appearance of PIN warrants increased surveillance of the prostate for development of an invasive carcinoma because the presence of PIN that is high grade suggests an increased risk for subsequent appearance of adenocarcinoma.

PIN itself is not an indication for aggressive treatment. Lipski et al, Adenocarcinoma of the prostate is common. Many of these carcinomas are small and clinically insignificant. However, some are not, and prostatic adenocarcinoma is second only to lung carcinoma as a cause for tumor-related deaths among males.

Bostwick et al, Men with a higher likelihood of developing a prostate cancer in the U. Those with an affected first-degree relative have a much greater risk. Prostate cancers may be detected by digital examination, by ultrasonography transrectal ultrasound , or by screening with a blood test for prostate specific antigen PSA.

None of these methods can reliably detect all prostate cancers, particularly the small cancers. Widespread PSA screening is not cost-effective.

Men whose life expectancy is less than 10 years not pursue prostate cancer early detection because the likelihood of benefitis outweighed by the risk of harms from treatment.

Men at higher risk for prostate cancer at earlier ages, including men of African American ancestry or a family history of prostate cancer in nonelderly relatives, should be provided the opportunity for informed decision making at an earlier age than average-risk men.

Wolf et al, A mildly increased tPSA in a patient with a very large prostate can be due to nodular hyperplasia, or to prostatitis, rather than carcinoma. The cPSA has a greater sensitivity for prostatic adenocarcinomas at the low ranges of elevation. Transrectal needle biopsy, often guided by ultrasound, is useful to confirm the diagnosis, although incidental carcinomas can be found in transurethral resections for nodular hyperplasia.

Jung et al, Demura et al, Prostatic adenocarcinomas are composed of small glands that are back-to-back, with little or no intervening stroma. Cytologic features of adenocarcinoma include enlarged round, hyperchromatic nuclei that have a single prominent nucleolus. Mitotic figures suggest carcinoma. Pearson et al, Prostatic adenocarcinomas are usually graded according to the Gleason grading system based on the pattern of growth.

There are 5 grades from 1 to 5 based upon the architectural patterns. These two grades are added to get a final grade of 2 to Dihydrotestosterone and the prostate: the scientific rationale for 5alpha-reductase inhibitors in the treatment of benign prostatic hyperplasia.

Still, other factors are also important, such as:. Grade Groups are a new way to grade prostate cancer to address some of the issues with the Gleason grading system. As noted above, currently in practice the lowest Gleason score that is given is a 6, despite the Gleason grades ranging in theory from 2 to This understandably leads some patients to think that their cancer on biopsy is in the middle of the grade scale.

Another problem with the Gleason grading system is that the Gleason scores are often divided into only 3 groups 6, 7, and Similarly, Gleason scores of 9 or 10 have a worse prognosis than Gleason score 8. Although eventually the Grade Group system may replace the Gleason system, the two systems are currently reported side-by-side.

These are special tests that the pathologist sometimes uses to help diagnose prostate cancer. Not all patients need these tests. Whether or not your report mentions these tests has no effect on the accuracy of your diagnosis. Perineural invasion means that cancer cells were seen surrounding or tracking along a nerve fiber within the prostate. When this is found on a biopsy, it means that there is a higher chance that the cancer has spread outside the prostate.

In some cases, finding perineural invasion may affect treatment, so if your report mentions perineural invasion, you should discuss it with your doctor. It is not important in someone who already has prostate cancer. In this case, the term 'high-grade' refers to the PIN and not the cancer, so it has nothing to do with the Gleason score or how aggressive your cancer is.

Inflammation of the prostate is called prostatitis. In some cases, inflammation may increase your PSA level, but it is not linked to prostate cancer. The finding of prostatitis on a biopsy of someone with prostate cancer does not affect their prognosis or the way the cancer is treated.

All of these are terms for things the pathologist might see under the microscope that are benign not cancer , but that sometimes can look like cancer. Atrophy is a term used to describe shrinkage of prostate tissue when it is seen under the microscope. When it affects the entire prostate gland it is called diffuse atrophy.

When atrophy only affects certain areas of the prostate, it is called focal atrophy. Focal atrophy can sometimes look like prostate cancer under the microscope.

Atypical adenomatous hyperplasia which is sometimes called adenosis is another benign condition that can sometimes be seen on a prostate biopsy. The seminal vesicles are glands that lie just behind the prostate. Sometimes part of a seminal vesicle is sampled during a biopsy. This is not a cause for concern.

Finding any of these is not important if prostate cancer is also present. This series of Frequently Asked Questions FAQs was developed by the Association of Directors of Anatomic and Surgical Pathology to help patients and their families better understand what their pathology report means. Understanding Your Pathology Report: Prostate Cancer When your prostate was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist.

What does it mean if my biopsy report mentions the word core? What is adenocarcinoma? What is the Gleason grade or Gleason score? If the cancerous tissue looks much like normal prostate tissue, a grade of 1 is assigned. If the cancer cells and their growth patterns look very abnormal, a grade of 5 is assigned.

Grades 2 through 4 have features in between these extremes. What does it mean to have a Gleason score of 6, 7, 8, or ? Difficult because antibiotics penetrate poorly into prostate.

As prostate cancer histology, especially Gleason score, plays a critical role in predicting patient outcomes, attempts have been made to refine histologic classification and reporting in prostate cancer to facilitate patient risk stratification.

This review discusses recent updates in prostate cancer grading and reporting. For several decades, the original Gleason system was used to grade acinar adenocarcinomas based on architectural features, with excellent correlation with clinical outcomes. However, in the past ten to fifteen years, it has become apparent that further refinement of the original Gleason grades is possible, with improved correlation with patient outcomes.

Indeed, much of the recent prostate pathology literature has focused on attempts to optimize pathologic grading and reporting of prostatic adenocarcinoma in support of ongoing clinical efforts to select optimal treatment for prostate cancer PCa patients by minimizing treatment-related morbidity while maximizing therapeutic benefit and quality of life. In this article, Gleason grade or Gleason pattern refers to the current ISUP consensus on Gleason grading, 1 unless otherwise specified.

Diagnosis and clinical implications of intraductal carcinoma also are covered, and general recommendations for use of immunohistochemistry in the differential diagnosis of PCa are briefly discussed.

Variant histologic patterns of prostatic adenocarcinoma and rare prostate tumors such as stromal neoplasms and lymphomas are not discussed. In , the ISUP convened a panel of expert urologic pathologists and clinicians to address issues related to PCa grading; 1 the recommendations of the panel were adopted by the WHO in the classification of prostate tumors.

Figure 1 illustrates the current state of Gleason grading in comparison with the original system proposed by Gleason himself. The main updates to Gleason grading in the ISUP consensus are related to diagnosis of Gleason pattern 4: all cribriform, glomeruloid, and fused or poorly formed glands visible at 10x magnification are considered Gleason pattern 4, though identification of only occasional poorly formed or fused glands between other wise well-formed glands does not warrant a diagnosis of pattern 4.

Additionally, the ISUP consensus specifies that mucinous adenocarcinoma, in which extravasated pools of mucin are seen in the stroma around cancer glands, should be graded based on the architecture of the glands themselves rather than uniformly be assigned Gleason pattern 4.

Pools of mucin associated with other wise well-formed tumor glands should be considered Gleason pattern 3 rather than pattern 4. The consensus points also include that any amount of comedonecrosis warrants a diagnosis of pattern 5, branched glands are permitted in Gleason pattern 3, and intraductal carcinoma discussed later should be reported but not graded.

Histologic features of treatment effect include luminal collapse, poorly formed glands, nuclear pyknosis, and overall decrease in the number of glands.

Metastatic tumor deposits also are not assigned a Gleason score. Alpha-reductase inhibitors e. Illustrates the current state of Gleason grading in comparison with the original system proposed by Gleason himself. In order to facilitate better communication of the pathologic diagnosis to clinicians and patients, the ISUP consensus recommends adoption of so-called grade grouping, as proposed by Epstein et al.

Gleason score 8 tumors comprise grade group 4, and Gleason score 9 or 10 falls into the worst prognostic group grade group 5. Translation of Gleason scores 6—10 into grade groups 1—5 is designed, at least in part, to clearly communicate to patients that Gleason score 6 is a well-differentiated tumor with an overall excellent prognosis.

In contrast, a patient receiving a diagnosis of Gleason score 6 on a scale of 2—10 may be understandably confused when told that his tumor has essentially the best prognosis for PCa. Although the underlying motivation for changes in PCa grading and grade grouping are well intentioned, there are lingering issues related to diagnosis and reporting of high-grade adenocarcinoma Gleason patterns 4 and 5 in particular.

One critical point is that cases with a tertiary Gleason pattern were explicitly excluded in the description of the grade groups; 4 as such, grade groups cannot be applied in cases with tertiary patterns. Recent studies to evaluate the prognostic impact of Gleason pattern 4 have focused on how best to quantitate Gleason pattern 4 e.

Although a consensus has not yet been reached on issues related to diagnosis and quantitation of Gleason patterns 4 and 5 as discussed immediately above , the ISUP and College of American Pathologists CAP do currently recommend reporting the percent of tumor that is Gleason pattern 4 or 5.

Additionally, it is purported that routine reporting of the percent Gleason patterns 4 and 5 will be useful for future studies on outcomes. The main differential for intraductal proliferations are high-grade prostatic intraepithelial neoplasia HGPIN , intraductal prostatic carcinoma IDC , and extension of urothelial carcinoma into prostatic ducts.

HGPIN-like adenocarcinomas have been described, but these also lack basal cells. Use of basal cell markers is probably not useful in cases that also harbor frank high-grade invasive carcinoma, as the presence of IDC is not especially important in this setting.

Immunostaining is particularly useful in differentiation of IDC versus extension of urothelial carcinoma into prostatic ducts. It is important to note that ductal carcinoma of the prostate formerly referred to as endometrioid variant in reference to its columnar epithelial cell morphology is a separate entity from what is diagnosed as intraductal carcinoma, despite having a similar name.

Stains useful in differentiating PCa from urothelial carcinoma are mentioned in the discussion of intraductal carcinoma above. One consideration is the presence or absence of basal cells in focal areas of small glands. The basal cell layer may be incomplete or even only focally retained in foci of partial atrophy, adenosis, or in outpouchings of HGPIN.

Careful scrutiny is required to determine whether the basal cell layer in focal small glands is truly lost or merely incomplete. A diagnosis of focal glandular atypia or atypical small acinar proliferation may be warranted, if histologic and immunophenotypic features are not definitive for carcinoma.

However, issues remain regarding diagnosis and quantification of high-grade patterns in particular. Pathologists continue to play an essential role in guiding care in PCa patients. Jennifer K. Louis, Missouri. National Center for Biotechnology Information , U.
