visible
need to rule out malignant causes first
describe the referral criteria for patients with haematuria?
Suspected cancer pathway referral (for appointment within 2 weeks) for bladder cancer if
-Over age 45 and have; Unexplained VH without UTI
or VH persisting or recurs after treatment of UTI

describe the role of PSA testing?
- must be interpreted with caution due to the natural increase in PSA with age, benign prostatic hypertrophy and with prostatitis.
- The early results of screen- ing for prostate cancer have varied greatly from no benefit in a low-risk population to a halving of deaths from prostate cancer in a general population study but with no overall reduction in mortality.
- Currently national screening pro- grammes are not recommended.
describe the histology of germ cell tumours?
seminoma embryonal cancer teratoma mature, immature or with malignant differentiation choriocarcinoma endodermal sinus tumour mixed teratoma
what are the signs and symptoms of testicular/germ cell cancers?
testicular mass often painful
para-aortic lymph nodes with back pain and gynaecomastia if hCG secreting
what are the investigations and surgery for testicular/germ cell tumours?
- ultrasound or MRI of testicle
- assay of serum tumour markers (alpha fetoprotein, beta hCG, lactic dehydrogenase
- urinary pregnancy test for hCG
- CT or MRI for metastases
- surgery for men is by inguinal approach to avoid spillage of highly metastatic tumour in scrotum
describe the features of seminomas?
least common and are radiosensitive and chemosensitive
associated with raised LDH but only a mildly raised bete hCG and never a raised AFP
what is the treatment for seminomas
Stage 1 disease limited to gonad with 30% 5 year risk or recurrence with surgery alone
adjuvant therapy with chemotherapy or radiotherapy to para-aortic lymph nodes leads to over 95% cure in early stage disease but chemotherapy with single agent cisplatin or carboplatin doesnt have long term risks of secondary malignancy associated with radiotherapy
intensive surveillance can be given with treatment for those who repalpe with equally high cure rate since combination chemotherapy will cure 90% of visible metastatic disease
give examples of combination chemotherapy?
cisplatin
etoposide
bleomycin
what is the treatment and features of teratomas?
- adjuvant chemotherapy for those at moderate to high risk with cisplatin, etoposide and bleomycin leads to 95% cure rate
- no vascular invasion may only require single cycle treatment instead of lymph node dissection
- metastatic-usually involves para-aortic lymph and lyngs, spread rapidly and cause organ failure.
- gynaecomastia and positive pregnancy test
- 80% of teratomas express either beta hCG or AFP and all metastatic have elevated LDH
- infertility in 20% due to azospermia
