Cervical carcinoma Flashcards
Green
At what age is cervical cancer classically seen?
Two peaks:
30-39yrs
70+yrs
What is associated with cervical cancer?
High risk assoc with HPV 16 and 18 Risk factors as for CIN Immunosuppression (e.g. HIV or steroids) accelerates invasion from CIN FHx cervical cancer not relevant Smoking COCP
How does cervical cancer present?
Cervical smear abnormal i.e. showing invasion (unreliable)
Incidental finding on LLETZ treatment of CIN (occult carcinoma)
PCB and/or PMB
Watery vaginal discharge
Features of advanced disease
-heavy PV bleed
-ureteric obstruction
-weight loss
-bowel disturbance
-vesicovaginal fistula
-pain, haematuria, renal failure (bladder invasion)
How common is cervical cancer?
3000 new cases diagnosed annually
1000 deaths/year
Incidence decreased by 50% between 1980’s-2000’s (screening), but rates on rise again in young women
What is the pathology of cervical cancer?
90% squamous cell carcinoma
10% adenocarcinoma (from columnar epithelium - worse prognosis)
Why is HPV vaccination important?
99.7% cervical cancer found to contain HPV DNA
Given to all young girls as prophylaxis
What may be seen on examination of a patient with cervical cancer?
Ulcer/mass visible or palpable on cervix, cervix may also be normal in early disease
Look for uptake of 0.5% acetic acid
Hardened cervix on bimanual (may be fixed in advance disease)
On speculum, cervix may bleed on contact
What Ix would be performed in suspected cervical cancer?
Bloods (FBC, U&E, LFT)
Punch biopsy for histology (LLETZ contraindicated as bleeds heavily and not definitive treatment)
CT abdo pelvis/MRI for staging (also examination under anaesthetic
What staging classification is used for cervical cancer?
FIGO
Stage 1 - confined to cervix (1a= microscopic, 1b= macroscopic)
Stage 2 - extended locally to upper two-thirds of vagina (2b= if to parametria)
Stage 3 - spread to lower third of vagina (3a) or pelvic wall (3b)
Stage 4 - spread to bladder/bowel (4b= spread to distant organs)
How is cervical cancer managed?
Stage 1a1 (<3mm depth): local excision e.g. cone biopsy(fertility sparing) or hysterectomy
Stage 1a2 (<5mm depth) and 1b1 (<4cm diameter): lymphadenectomy and, if node negative, Wertheim’s hysterectomy
Stage 1b2 (>4cm diameter) and early 2a: chemotherapy (if -ve LN biopsy, consider Wertheim’s)
>Stage 2b: combination chemotherapy
Stage 4b: chemoradiotherapy, palliative radiotherapy for bleeding control
What is the main chemotherapeutic agent used in cervical cancer management?
Cisplatin
What complications are associated with Wertheim’s (radical) hysterectomy and lymphadenectomy?
Big four
Ureteric fistula
Bladder dysfunction
Lymphoedema
What complications are associated with radiotherapy?
Acute bladder and bowel dysfunction
- Tenesmus
- Mucositis
- Bleeding
- Ulceration
- Strictures and fistula formation
- Vaginal stenosis, shortening, dryness
What is the prognosis of cervical carcinoma?
5yr survival rates:
Stage 1a = 95% Stage 1b = 80% Stage 2 = 60% Stage 3-4 = 10-30% LN involved = 40% LN clear = 80%
Overall - 65%
How is cervical cancer managed?
Conservative -Cone biopsy -Radical trachelectomy -Simple hysterectomy Radical -Radical hysterectomy (open/laparoscopic) -Radical radiotherapy +/- chemotherapy -Exenterative surgery
