Cancers - GU Flashcards
Bladder Carcinoma
- usually adults-50-70 yo, rare under 40, White, Male
- The age-adjusted incidence rate was 20.8 per 100,000 men and women per year.
- 2013 estimated from NCI in US: New cases: 72,570, Deaths: 15,210
Risks-
- Environmental toxins- chemicals-like Beta Naphthylamine,4-amino-diphenol Other Chemicals include arsenic and chemicals used in the manufacture of dyes, rubber, leather, textiles and paint products.
- Chronic inflammation –infections- recurrent cystitis, schistosomiasis (sq cell), urinary catheter indwelling or repeated use
- Radiation
- Smoking
- Chemo history especially Cytoxin
- Personal h/o bladder cancer
- Lynch syndrome-hereditary nonpolyposis colorectal cancer=increase GU cancers
Bladder cell types
- Most common-Transitional cells=inner bladder lining
- Squamous cells are thin and flat-usually result of inflammation (schistosomiasis)
- Adenocarcinoma-secrete mucous-rare in US.
Bladder Cancer Symptoms
Changes:
- Frequency
- Color- dark yellow, bright red, bloody, cola colored, or no change
- Painful urination
- Back Pain
- Pelvic Pain
Diagnosis of Bladder Cancer
Urinalysis-
- Microscopic hematuria
- Urine cytology
- Cystoscopy
- Biopsy of the bladder
- X-rays-CT or IVP to look at structures
- Blood test in near future noting immune cell methylation pattern is present.
Bladder Cancer Treatment
- Depends on type and stage
- Chemo-IV or Intravesical
- Immunotherapy: Interferon-Alpha2B-turn on immune sx, BCG-Bacille Calmette-Guerin-used in Tb
- Radiation
- Surgery
- Cystectomy total or partial
- Create alternative urine exit
- Neobladder-intestinal reservoir attached to urethra
- Cutaneous Continent Urinary Diversion-intestinal reservoir catheter to abdominal opening
- Urinary Conduit-to Urostomy bag
Renal Cell Carcinoma
-Kidney Cancer or Renal Adenocarcinoma
-Age-adults
-Male
-Obesity
Risk factors
-HTN
-Renal failure treatment
-Chemicals
-Von Hippel-Lindau disease-multiple tumors
-Hereditary papillary renal cell carcinoma
-smoking
Cancer in the renal tubules-adenocarcinoma
Estimated 2013 New cases: 65,150
Deaths: 13,680
Renal Cell Carcinoma - sxs
- Blood in the urine
- A lump in the abdomen
- A pain in the side that doesn’t go away.
- Loss of appetite
- Weight loss for no known reason.
- Anemia
Renal Cell Diagnosis
- Symptoms previously
- No reliable blood markers
- Differential- bladder cancer, cystitis, urinary tract infection, if only red-food eg beets then no blood on urinalysis
- Blood test-BUN/Creat
- Urinalysis-cytology-microblood-proteins
- Xrays-CT, MRI-(old KUB or IVP)
- Biopsy of kidney
Renal Cell Treatment
Surgery
-Nephrectomy-remove entire kidney-laproscopic
-Partial nephrectomy-open procedure remove tumor
Radiation to affected areas
Ablation
-Cryoablation-gas cold to freeze the tumor
-Radiofrequency ablation-electric current to burn or heat up cancer cells
Chemotherapy-for metastatic disease
Biologic Therapy-Antibody cells or substances made by body or lab infused that are stimulated to kill the cancer cells
Targeted Therapy-
-Antiangiogenic drugs to stop blood vessel growth to tumor
-Eg: Monoclonal antibodies or Kinase inhibitors-to stop growth
Wilms Tumor
What: Nephroblastoma=Embryonal Kidney Tumor
Where: may be uni or bilateral
-children usually 3-4 yo less common over 5yo
-Female
-Black
-Family member with Wilm’s
Associated with
-Aniridia*-iris in part color partially formed
-Hemihypertrophy-one side of body larger than other
-Undescended Testicles-Cryptorchidism
-Hypospadias-urethral opening on underside of penis
Conditions with high risk of Wilm’s
-WAGR syndrome has *, Gu abn and MR
-Denys-Drash syndrome-pseudohermaphroditism, boy with testes but female in look
-Beckwith-Wiedemann syndrome- abd org protrude at umbilical cord, macroglossia,enlarged internal organs
Wilms Tumor Symptoms
- Abdominal swelling
- An abdominal mass you can feel
- Abdominal pain
- Fever
- Blood in the urine
- Often picked up on routine health exam
Wilm’s Diagnosis
- Physical exam
- Blood and Urine tests-not diagnostic
- Imaging-U/S, CT, MRI
Wilm’s Staging
- Stage I. The cancer is found only in one kidney, and generally can be completely removed with surgery.
- Stage II. The cancer has spread to the tissues and structures near the affected kidney, such as fat or blood vessels, but it can still be completely removed by surgery.
- Stage III. The cancer has spread beyond the kidney area to nearby lymph nodes or other structures within the abdomen, and it may not be completely removed by surgery.
- Stage IV. The cancer has spread to distant structures, such as the lungs, liver, bones or brain.
- Stage V. Cancer cells are found in both kidneys
Treatment Wilms
-Surgery- Simple nephrectomy, Partial nephrectomy, Radical Nephrectomy -Chemo -Radiation
Prostate Cancer
- Age-men rare under 40 yo, usually >60yo, most common cause of death >75 yo,
- Family hx-father, brother
- Black race
- Exposure to: Agent Orange, Cadmium, Drinking too much ETOH
- Occupational-Farmers, Tire Plant Workers
- Diet-high fat esp animal fat(rare in Vegetarians)
