Gleason Score & Prostate Cancer Treatments - Memorial Sloan Kettering
There is a worldwide debate involving clinicians, uropathologists as well as patients and their families on whether Gleason score 6 adenocarcinoma should be labelled as cancer. There are those in favor of continuing to call it cancer, while others are in favor of removing the label of cancer from Gleason 6 tumors [ 1 - 5 ].
Such hot debate is based on both clinical data and personal view. Those who speak in favor of leaving the label of cancer base their opinion on the fact that Gleason score 6 cancer is composed of Gleason pattern 3 cancer, acinar adenocarcinoma della prostata Gleason score 3 shares cytological and molecular alterations associated with higher Gleason patterns and has the ability to extend locally beyond the prostate and metastasize [ 2 ].
A recent paper by Ross et al. Finley et al. We report a case of man diagnosed with low risk Gleason score 6 acinar adenocarcinoma whose radical prostatectomy specimen was reported to harbor Gleason score 6 adenocarcinoma with lymphovascular invasion and metastasis in a periprostatic lymph node. The case presentation includes an epilogue that could better explain the tumor behavior. There was no history of other medications or hormonally-active supplements.
No comorbidities, including diabetes, were present. His most recent preoperative total serum PSA was 7. Transrectal ultrasound revealed a hypoechoic area in the left mid part of the prostate. Induration of the same prostate zone was detected by digital rectal examination. Twelve random ultrasound acinar adenocarcinoma della prostata Gleason score 3 prostatic needle cores were taken.
The tumor was classified in the low risk category. Even though the patient was considered a potential candidate for active surveillance, open radical prostatectomy monolateral nerve sparing in the right side was performed.
Pelvic lymph node dissection was not carried out. The prostate specimen was received fresh from the operating room. Its weight without the seminal vesicles 33 grams and all three dimensions were recorded, the latter used for prostate volume calculation The seminal vesicles were cut into two halves and processed in acinar adenocarcinoma della prostata Gleason score 3.
Staging was done according to the TNM revision [ 10 ]. The nodule, 1. The left posterolateral periprostatic adipose tissue, adjacent to the prostate dominant cancer nodule, contained a lymph node, 0.
Whole mount section. The dominant nodule, contained in the circled area, with acinar adenocarcinoma Gleason score 6 Insert A ; thin bleu arrow and lymphovascular invasion insert B ; thin green arrow. The adjacent periprostatic fat tissue shows a lymph node thick red arrow with metastasis acinar adenocarcinoma della prostata Gleason score 3 pink part of the lymph node. In our current presentation, the index tumor consisted of variably sized individual well-formed gland, without cribriform glands, acinar adenocarcinoma della prostata Gleason score 3 cells and glomeruloid features, i.
The same score was observed in the biopsy, dominant nodule of the specimen and lymph node deposit. The Gleason grading system of prostatic carcinoma is the quintessential prognostic factor in predicting findings in radical prostatectomy, biochemical failure, local recurrences, lymph node or distant metastasis in patients receiving no treatment, radiation therapy, radical prostatectomy and other therapies, including cryotherapy and high intensity focal ultrasound therapy [ 911 - 13 ].
Clinicians use routinely various tools, such as Partin tables or Kattan nomograms, to predict outcomes, including pathological stage or prognosis following treatment [ 1415 ]. All of these tools incorporate the Gleason score.
Lesions previously referred to as Gleason scores 2 to 4 in the classic system are now assigned a higher grade Gleason score 6 in the modified system; however, those previously graded as Gleason score 6 in the classic system are often graded as Gleason score acinar adenocarcinoma della prostata Gleason score 3 tumors in the modified system.
It has recently been recommended by Dr JI Epstein that all cribriform patterns are diagnosed as Gleason pattern 4 rather than pattern 3. It has also been suggests that glomerulations most likely represent an early stage of cribriform pattern 4 cancer and should likely be graded as pattern 4. The general theme of such changes was to limit the definition of pattern 3 carcinoma and widen the scope of pattern 4 carcinoma. The Gleason system and its revisions are based on the architectural patterns of PCa.
The contribution of nuclear morphology to its further refinement has been investigated only to a limited extent. This was recently confined in a morphometric study in which it was shown that the nuclear signature is important to better define risk groups in PCa patients acinar adenocarcinoma della prostata Gleason score 3 17 ].
In our current case the WHO grade was 3. Based on the findings of the present case, it is suggested that, in those patients who meet the current criteria for active surveillance, the tumor should also be evaluated for the presence of a WHO grade. If this finding is observed, the patient should be further evaluated for the presence of additional prognostic factors that can better define the aggressiveness of the lesion and require immediate therapy. This is a reproduction of the original diagram given by Dr Mostofi to one of the authors RM.
Patients with Gleason score i. Our case showed LVI in the peritumoral parenchyma. LVI has been defined as the unequivocal presence of tumor cells within endothelial-lined spaces with no acinar adenocarcinoma della prostata Gleason score 3 muscular walls or as the presence of tumor emboli in small intraprostatic vessels.
Baydar et al. Studies have demonstrated an association between the presence of lymphovascular invasion and decreased time to biochemical progression, distant metastases, and overall survival after radical prostatectomy [ 18 - 20 ]. Our case showed metastasis in a periprostatic lymph node, i. In the study by Kothari et al. Sizes ranged from 0. Distribution was 2 of 39 5. A recent study by Hansen et al. These findings implicate that patients who seem to have low-risk PCa may harbor PCa metastases within lymph nodes of the periprostatic fat even if they do not have positive pelvic lymph nodes.
Von Bodman et al and Briganti et al reported that the number of positive lymph nodes affects prognosis in PCa patients with lymph node metastases acinar adenocarcinoma della prostata Gleason score 3 reported cut-offs of 1 and 2 positive lymph nodes associated with adverse disease-related outcomes, respectively [ 2324 ]. When the paper based on the current case was considered acinar adenocarcinoma della prostata Gleason score 3 for submission, we thought about a possible comment from a reader: Was the paraffin block containing the prostate slice with the dominant nodule and the lymph node serially sectioned to see whether the lesion changed in deeper sections?
To give an answer to this possible question, deeper sections were cut to the point that almost all the slice was sectioned. This lead us to acquire some information on the follow-up of acinar adenocarcinoma della prostata Gleason score 3 patient whose radical prostatectomy was done in He is under complete androgen blockade therapy for a postoperative rising PSA levels and pelvic lymph node metastasis.
They found that 2 of their cases had tertiary pattern 4 with small cribriform glands. However, it was unknown whether it was the tertiary pattern 4 to confer the metastatic potential to the disease.
An answer to this was given by Haffner et al. They tracked the evolution of the lethal cell clone from the primary cancer to metastases through samples collected during disease progression and at the time of death. Surprisingly, these analyses revealed that the lethal clone arose from a small Gleason pattern 3 cancer focus in the primary tumor, and not from the bulk, higher-grade primary cancer or from a lymph node metastasis resected at prostatectomy.
