Study Notes
- The presentation focuses male genito-urinary tract pathology, including prostate, testis, penis, and scrotum.
- Learning outcomes covered include congenital abnormalities, phimosis, genital warts, tumours, infections, benign prostatic enlargement, and prostatic carcinoma.
Prostatitis
- This is mostly clinical relevant and not often a specific query to a histopathologist.
- PSA levels can increase, raising concern for cancer.
- Acute bacterial prostatitis is often seen in UTIs, mostly affects adult men, and has systemic/local symptoms.
- Chronic bacterial prostatitis is similar to acute, but relapsing with lesser symptoms.
- Granulomatous prostatitis is uncommon, caused by infectious or unknown factors, mimics other types of prostatitis.
- Granulomatous prostatitis can have very high PSA and a hard prostate on DRE, which mimics cancer clinically.
Basic Prostate Anatomy
- Transitional zone is where BPH occurs occurs in this zone, and 20-25% of cancers
- Peripheral zone is where 70-75% of cancers occur.
Benign Prostatic Hyperplasia (BPH)
- It's a very common disorder, frequently referred to urologists, and is caused by hormonal, age-related, and genetic factors.
- Symptoms of prostatism include obstructive issues like poor flow, hesitancy, incomplete bladder emptying, and dribbling plus irritative symptoms such as urgency and frequent urination including nocturia from the bladder.
Prostate Cancer (PCa)
- PCa includes primary tumors like adenocarcinoma - including microacinar and ductal variants - and rare forms such as squamous/small cell carcinomas
- Secondary tumors are rare, usually direct extensions from bladder or rectal cancer.
- Approximately 3400 new cases occur in Ireland per year, with fewer than 550 deaths, making it a common cancer in men, but with moderate associated mortality.
- Autopsy studies find that up to 50% of men over 60 have prostate cancer.
- Early-detected prostate cancers have over 95% 5-year survival.
- The lifetime risk of prostate cancer diagnosis is 16% in the US, while the risk of dying from it is 2.9%, indicating indolent behavior.
- Symptoms are often incidental, found via PSA tests, DRE, or during BPH resections, can be local mimicking BPH or metastatic, e.g. to bone.
- Prostate Specific Antigen is a small glycoprotein from prostatic epithelial cells to liquefy semen that is leaked into serum with normal levels < 4 ng/mL, may increase due to cancer but has other reasons, and is widely used for screening.
- The FDA approved PSA as screening tool in 1994 and incidence stabilised since 2010 (3300-3500/annually)
- The pathway for PCa diagnosis starts with symptoms, leading to S-PSA testing, and if high, a biopsy, that, if positive, leads to treatment, with the cycle starting again if testing comes back negative.
Traditional Prostatic Biopsy
- This involves transrectal extended sextant biopsies taking 12 cores.
- Pathological features are often subtle. Macroscopic features include being multifocal, as well as being infiltrative and often unseen. Microscopic features include minimal pleomorphism, infrequent mitoses and typically occur in small foci.
- Histological features include small crowded glands, nuclear enlargement, large nucleoli, and a lack of basal myoepithelial cells, with immunohistochemistry
- There is no single defining feature.
- Main limitations include a lack of targeting, negative results may not mean there is no cancer and extent and grade may not reflect actual cancer extent and grade in prostate.
TNM Staging for Prostate Cancer
- T1 is incidentally detected, including T1a/b from TURP and T1c from needle core.
- T2 is confined to prostate, T3 is extraprostatic, and T4 invades the adjacent organ.
- Regional nodes (N0/N1) and distant sites (M0/M1) indicate spread; iliac lymph nodes often spread first before bone metastes.
- Pathological and clinical T staging are a little bit different.
Gleason Scoring
- The Gleason score is based purely on the patterns of the glands.
- Patterns 1-2 are rarely sued, pattern 3 has single well formed glands, pattern 4 has poorly formed or fused glands, and pattern 5 has no glands just single cells, sheets and rows.
- Gleason Score = Predominant pattern + Second pattern
- New system is 6-10 even though theory it is 2-10
- Gleason score 6
- Gleason score 3+4=7
- Gleason score 4+3=7
- Gleason score 8
- Gleason score 9-10
High Risk Prostate Cancer
- High-risk prostate cancers account for 15% of diagnosed cancers.
- Clinical stage T3, Gleason score >8 and or, PSA >10
Solutions to Problems with Prostate Cancer
- Solutions involve improving early imaging with MRI, and better biopsies that offer targeted biopsies for MRI lesions or use template biopsies.
- MRI with PI-RADS is useful for identification, along with T2W, diffusion dynamic studies that score from 1-5, 1='most probably benign'; 5='most probably malignant' 3 is indeterminate and a problem group')
Newer Prostatic Biopsies
- Template biopsies are transperineal with better access to anterior base and apex that is used on persistent concerns despite negative biopsies
- Targeted prostate biopsies that use MRI to target lesions.
- MRI is considered if S-PSA is high and if PI-RAD (3)-4-5 is performed, which leads to more targeted biopsies, but if the result is PI-RAD 1-2, then no biopsy is performed.
Testis Pathology
- Concerns germ cell, sex chord, lymphoma and metastasis tumors, and other not not tumors lumps such as infections and cysts.
- Cryptorchidism has an unknown cause that occurs when the testis fail to descend into scrotum. It may cause atrophy, infertility, and increased cancer risk in both testes. Orchidopexi before puberty is a solution. Seen in some congenital syndromes e.g. Prader-Willi
- Tumors are typically seminoma or non-seminoma.
- Benign cysts and 'celes' include varicoceles and hydroceles.
- Varicocele is dilated tourtuous veins in spermatic cord or varices that lead to fertility problems.
- Hydrocele is fluid collection in tunica vaginalis that can be due to infection, hernia, or be idiopathic
- Epididymal cysts, spermatocele are relating to epididymus
Inflammation and Torsion
- Orchitis or epididymo-orchitis can be caused by mumps (vaccine available), sexually transmitted diseases, or is idiopathic.
- Cases of torsion usually present in infants and those around puberty and result in severe pain that is seen as surgical emergency. Twisting of spermastic cord and testis
Testicular Tumours Basic Facts
- GCT is ~90% and are seminoma and or non-seminoma. Occurring at <10 for sex chord/stormal tumours from Leydig cells. Including rare tumours lymphomas and metastases in older men. They are malignant tumors
- Basic GCT Facts include that 175 cases per year occur in ireland and is the mean age is 30-40's and is most common solid tumour in young men, with >90 survival rate due to chemo and radiation with causes 5 deaths. Risk factors are that is more common in white populations than black, cryptorchidism. As well as rare e.g. Klinefelter syndrome and environmental factors
- Survival is very good due to chemo and radiation treatment- Risk Factors: Racial (white>black), Cryptochidism, Klienfelter, increasing incidence (environmental)?
Metastasis
- Spread via lymph nodes to para-aortic and upwards to the chest, does not to inguinal nodes.
- Can also spread Haematogenous to the lungs or brain, more common in non seminomas.
- T1 is limited to testis and T2 is limited to but invades through albignia including vascular invasions, and T3 is limited to the cord and T4 invades scrotum,
- Seminomas occurs in the Age peak of 40 and requires adjuvant radiation and does not have specific markers in blood but LDH is increased
- Non - seminomas Age peak the 30 and requires adjuvant chemo and secrete specific substances and requires (tumour markers’) such as hCG and AFP.
- Germ cell neoplasia in situ is in situ malignant and does is not able to spread.
Testicular Cancer Types
- The germ cell neoplasia in situ converts to Seminoma or to Non-seminoma. Seminoma is a distinct type. Non-seminoma types are Embryonal carcinoma, Teratoma, Yolk sac tumour ( Tumour marker = Alpha fetoprotein (AFP)) and Choriocarcinoma ( Tumour marker = human chorionic gonadotropin (hCG)) including combined tumors.
- Overall these can result in blood results due to tumour markers. And metastasise.
Penis/Scrotal Pathology
- Penis/scrotal Pathology is a congenital abnormality causing Hypospadia > epispadia which is an abnormal opening of urethra is usually normal.
- Phimosis is inability to retract foreskin from gland penis that usually occurs with chronic inflammation due to poor hygiene, this is a normal occurrence for young boys
- Balanitis xerotica obliterans are causes from inflammation and Lichen sclerosus
- An inflammatory response can be caused by sexually transmitted diseases like herpes/syphilis/ Gonorrhoea and chlamydia and can causes inflammation in the urethra . - Multiple sexually transmitted disesases can cause genital warts due to HPV and can causes a higher risk of penile cancer.
Penile cancer
- It has a rare with < 20 cases per year in Ireland
- Is almost all squamous cell carcinoma are usually seen in males > 55 y/o
- Is caused by. Infection: Usually associated with HPV and history of genital warts ,Hygiene: Phimosis, poor hygiene and: Lichen sclerosus (or BXO)
- Spreads usually to lymph node first.
TNM System for Penial Cancer
- For TNM System pTis Carcinoma - PT invasion of subepithelial tissues, pT2 Invasion of corpus spongiosum* pT3 and pT4 Invasion of corpus cavernosum /adjacent structures * +/- invasion of urethra - Inguinal nodes first affected
