Gynae-Oncology Flashcards
RFs for cervical cancer
HPV 16 and 18
Smoking
HIV
Multiple sexual partners
What are the majority of cervical cell cancers?
The majority of cervical cancers are squamous cell carcinomas
Cervical cancer screening programme
Offered every 3 years from 25 to 49 years
Offered every 5 years from 50 to 64 years
Outcomes
Positive for HPV 16 and/or 18 AND abnormal morphology on cytological analysis –> Invite for Colposcopy
Positive for HPV 16 and/or 18 AND normal morphology on cytological analysis –> Repeat Smear in 1 Year
Negative for HPV 16 and/or 18 –> Routine Screening
Presentation of cervical cancer
Abnormal vaginal bleeding (often post-coital bleeding)
Abnormal vaginal discharge
What type of bleeding is often associated with cervical cancer?
post coital
When is cervical cancer usually identified?
Usually identified in the pre-cancerous stages (cervical intraepithelial neoplasia) during screening
Investigations for cervical cancer
Bedside
Speculum Examination
Imaging & Other
Colposcopy
Cervical Biopsy
CT or MRI (for staging)
What is used for staging of cevical cancer?
CT/MRI
How is cervical cancer staged?
Stage 1: Confined to cervix
Stage 2: Beyond the cervix but not to the pelvic wall or lower 1/3 of the vagina
Stage 3: Invading the pelvic wall or lower 1/3 of the vagina
Stage 4: Invading the bladder or rectum, or distant metastases present
NOTE: Think rule of 1/4rds
Management of stage 1A cervical cancer (preclinical lesion)
Can be excised with a clear margin
Management of stage 1B cervical cancer (clinically invasive cervical cancer)
Usually requires radical hysterectomy and bilateral pelvic node dissection (Wertheim’s hysterectomy)
If fertility-sparing surgery is required, a radical trachelectomy with pelvic node dissection may be considered
What may be done if fertility sparing surgery is requied in cervical cancer?
If fertility-sparing surgery is required, a radical trachelectomy with pelvic node dissection may be considered
NOTE: Done in stage 1B cervical cancer
Stage 1 cervical cancer
confined to cervix
stage 2 cervical cancer
Beyond the cervix but not to the pelvic wall or lower 1/3 of the vagina
stage 3 cervical cancer
Invading the pelvic wall or lower 1/3 of the vagina
stage 4 cervical cancer
Invading the bladder or rectum, or distant metastases present
When is radiotherapy used in cervical cancer?
If tumour has extended beyond the cervix (>stage 1, e.g. stage 2/3/4)
What is the mainstay of treatment if tumour has extended beyond the cervix?
radiotherapy
Two forms of radiotherapy used in cervical cancer
External Beam Radiotherapy
Usually given over 4 weeks
Internal Radiotherapy (Brachytherapy)
Involves the insertion of radioactive rods into the affected area
NOTE: Used if tumour has extended beyond the cervix (>stage 1, e.g. stage 2/3/4)
What are the majority of endometrial cancers?
adenocarcinomas
What are endometrial cancers assocaited with?
states in which oestrogen exposure is increased:
Hormone replacement therapy
Obesity
Polycystic ovarian syndrome
Nulliparity
Types of endometrial cancers
Type 1 (85%)
Subtypes: Secretory, Endometrioid, and Mucinous Adenocarcinoma
Tends to affect younger patients and is often oestrogen-dependent
Associated with better prognosis
Usually preceded by atypical hyperplasia
Type 2 (15%)
Subtypes: Papillary, Clear Cell and Serous
Tends to affect older patients and is less oestrogen-dependent
Associated with poorer prognosis as the tumours tend to be higher grade with deeper invasion
NOTE: “Sarah Eats Meat, Paul Can’t Stand it”
Mnemonic to remember types of endometrial cancer
“Sarah Eats Meat, Paul Can’t Stand it”
Type 1 (85%)
Subtypes: Secretory, Endometrioid, and Mucinous Adenocarcinoma
Type 2 (15%)
Subtypes: Papillary, Clear Cell and Serous
Who does type 1 endometrial cancer tend to affect?
Tends to affect younger patients, Type 2 Tends to affect older patients
is type 1 endometrial cancer oestrogen dependent?
Yes, type 2 is less oestrogen-dependent
Types of type 1 endometrial cancer
Secretory, Endometrioid, and Mucinous Adenocarcinoma
Which type of endometrial cancer has a better prognosis? Why?
Type 1, because type 2 tends to be higher grade with depper invasion
Which type of endometrial cancer tends to be higher grade
Type 2 –> Associated with poorer prognosis as the tumours tend to be higher grade with deeper invasion
Which type of endometrial cancer is preceded by atypical hyperplasia?
type 1
Presentaition of endometrial cancer
