Gynaecological and Breast Pathology Flashcards
What is screening
The process of identifying people who appear healthy but may be at an increased risk of disease or condition
What is the main aim of breast screening
To reduce mortality from breast cancer
Who is screened in the breast screening programme
50-70 years
Invited every 3 years
Mammography main tool
What is the breast triple assessment
Clinical examination (history, physical) Radiological examination (ultrasound, mammography) Pathological examination (core cut biopsy, FNAC)
How are the areas of breast triple assessment scored
P1, R1, B1: Normal P2, R2, B2: benign lesion P3, R3, B3: Atypical P4, R4, B4: Atypical, prob-malignant P5, R5, B5: malignant
Who are the members of the breast MDT
Surgeons Oncologists Radiologists Pathologists Specialist nursing team Research nurses Genetic counsellors
What are the synonyms of fibrocystic change
Fibrocystic disease Fibrous mastopathy Mammary dysplasia Schimmelbusch's disease Chronic cystic mastitis
What is fibrocystic change
Generally affects pre-menopausal women
Usually B/L and multifocal
Risk of FCC development is increased in women with hyperestogenism
No increased risk of subsequent carcinoma development
A constellation of benign, hormonally mediated breast changes including cyst formation, stroll fibrosis and mild epithelial hyperplasia without atypic
Symptoms cease 1-2 years following menopause
How does fibrocystic change present
Lumpy, premenstrually painful breasts
What is fibroadenoma
Common
Women 20-30 years
More common in Afro-caribbean women
Mobile, painless, well defined breast lump
How are fibroadenoma’s treated
Surgical excision
What is DCIS
Ductal carcinoma in situ
A malignant clonal proliferation of cells within breast parenchymal structures
No evidence of invasion
A precursor of invasive carcinoma
Most commonly identified as microcalifications on screening
Pure DCIS cannot produce metastasis
Can progress to invasion if left
What are the risk factors for breast cancer
Linked to oestrogen
Increased with early menarche, late menopause, obesity in postmenopausal women, OCP’s and normal therapy for menopause, alcohol
What should a path report tell about malignancy
In situ or invasive Type Grade Size Vascular invasion Nodal status Relationship to margins Molecular marker status
What are the main types of breast carcinoma
Ductal (75%) Lobular (12%) Tubular/cribriform (3%) Medullary (3%) Mucoid (2%) Metaplastic (1%) Others (4%)
What are the key prognostic factors
Tumour grade
Tumour size
Nodal status
What is the Nottingham Prognostic index
Grade + nodal status + 0.2 x tumour size
- 4 or less : good (80%+ 16 year survival)
- 41-5.4: moderate (46%)
- 41 +: poor (10%)
What is CIN
Cervical intraepithelial neoplasia
Dysplasia
Leads to squamous cell carcinoma
What is CGIN
cervical glandular intraepithelial neoplasia
Dysplasia
Leads to adenocarcinoma
What is VIN
Vulval intraepithelial neoplasia
Dysplasia
What is VaIN
Vaginal intraepithelial neoplasia
Dysplasia
What is AIN
Anal intraepithelial neoplasia
Dysplasia
What is dysplasia
Earliest morphological manifestation of multistage process of neoplasia
Cytological features of malignancy but no invasion
Removal is curative, if left then significant chance of developing invasive malignancy
What are the results of low risk HPV
Types: 6, 11
Lower genital tract warts (condylomata: benign squamous neoplasms), low grade INs
Very rare in malignant lesions
What are the results of high risk HPV
Types: 16, 18, 31, 33
High grade INs and invasive carcinomas
What are the HPV vaccines
Gardasil (HPV 6,11, 16,18)
Cervarix (HPV 16, 18)
What part of the cervix is vulnerable to the oncogenic effects of HPV
Transformation zone
What are the characteristics of CIN I
Regression 60%
Persistence 30%
Progression to CIN III 10%
Progression to invasion 1%
What are the characteristics of CIN II
Regression 40%
Persistence 40%
Progression to CIN III 20%
Progression to invasion 5%
What are the characteristics of CIN III
Regression 33%
Persistence ~56%
Progression to invasion 20-70%
What makes a good screening test
High sensitivity and specificity Not harmful Not too expensive Acceptable to population Define pre-invasive stage long enough to allow intervention Simple successful treatment Not a test for cancer
How are smear tests triaged
HPV triage
What is LLETZ
Large loop excision of the transformation zone
What are the FIGO staging of cervical carcinoma
I: Confined to cervix
II: Invades beyond uterus, not to pelvic side wall
III: Extends to pelvic wall, lower 1/3 vagina, hydronephrosis
IV: Invades bladder or rectum or outside pelvis
What are the treatments for each stage of cervical carcinoma
IA1, IA2: No need for radical treatment, complete excision with LLETZ
IB, IIA, IIB: Consider radical therapy with surgery or chemo or radiotherapy
III, IV: Consider palliative care, chemotherapy
What are the characteristics of Vulval squamous cell carcinoma
Associated with VIN Associated with inflammatory dermatoses Eroded plaque or ulcer Spreads locally to involve: -Vagina and distal urethra -Ipsilateral inguinal LNs Contralateral inguinal LNs, deep iliofemoral LNs
What is endometriosis
Presence of endometrial tissue at sites other than the endometrium
How do patients with endometriosis present
25% asymptomatic Dysmenorrhoea Dyspareunia Pelvic pain Subfertility Pain on passing stool Dysuria
How is endometriosis diagnosed
Laparoscopy
