Cervical Cancer Flashcards
What is the most common form of cervical cancer?
Squamous cell carcinoma, presenting as a malignant tumour on the cervix.
What is it heavily associated with?
Persistent human papilloma virus (HPV) infection. The majority of cases are squamous cell carcinoma.
What are 4 risk factors?
HPV 16 and 18 infection (accounts for 70% of cases)
Multiple sexual partners
Smoking
Immunosuppression (e.g. HIV or organ transplants)
What are clinical features?
Vaginal discharge
Bleeding (e.g. postcoital or with micturition or defaecation)
Vaginal discomfort
Urinary or bowel habit change
Suprapubic pain
Abnormal white/red patches on the cervix.
Pelvic bulkiness on PV examination
Mass felt on PR examination
What are 4 differentials and when would they be suspected?
Vaginitis: itching, burning, pain, and abnormal discharge
Cervicitis: abnormal discharge, pelvic pain, and postcoital bleeding
Endometrial cancer: abnormal vaginal bleeding, pelvic pain, and unintentional weight loss
Cervical polyps: abnormal vaginal bleeding, discharge, and pain during intercourse
What are the investigations?
Urgent colposcopy, which allows visualisation and biopsy of the cervix
CT chest/abdomen/pelvis is used for cancer staging
How are IA stage cancers treated?
Conisation with free margins if aiming to spare fertility
Conisation is done using a scalpel (cold-knife conisation), laser, or electrosurgical loop, and is usually performed as an outpatient.
What is a fertility sparing option apart from conisation?
Radical trachelectomy can be done for slightly more advanced, yet still early-stage cancers when the aim is to spare fertility. This involves removal of the cervix, the upper vagina and pelvic lymph nodes.
What can be used if sparing fertility not prioritised?
Laparoscopic hysterectomy and lymphadenectomy is offered for women for early-stage cancer.
What is used for infilitrating, invasive early metastatic cancer?
Radical (Wertheim’s) hysterectomy can be performed which involves removal of the uterus, primary tumour, pelvic lymph nodes, and sometimes the upper third of the vagina and uterovesical and uterosacral ligaments.
What is used for late stage cancer?
If the cancer has spread outside the cervix and uterus, then surgical management is often unlikely to be curative. These cancers are treated with radiotherapy and/or chemotherapy.
Who is cervical screening offered to?
For all women and people with a cervix between the age of 25-64 years.
Cervical sample is taken and tested for high-risk HPV viruses.
Patients are recalled every 5 years if normal.
What is the target of cervical screening?
To identify dyskaryotic cells which are pre-cancerous allowing management before invasive cancer can develop.
How are abnormal results divided up?
Borderline
Mild dyskaryosis
Moderate dyskaryosis
Severe dyskaryosis
Where should abnormal cytology be referred?
Colposcopy
