Basics Flashcards
Risk factors
Prior history of STDs, early age of first coitus, multiple sexual partners, multiparity, nonbarrier methods of birth control, smoking. ??immunocompromised
Spread pattern
Local
LN – usually sequential – parametrial LN, pelvic, common iliac, para-aortic and then scalene
What imaging needed
Imaging: CT and MRI
What Ex info needed?
Ex: parametrium, proctoscopy and cystoscopy
Histology types
Squamous (85%) Adeno (15%) verrucous carcinoma adenosquamous clear cell neuroendocrine undiff
Adenocarcinoma
Adeno: 15% no visible lesion, often stain CEA+
Verrucous
Verrucous: well-differentiated. Local recurrence, does not metastasize. Associated with HPV 6. Historically, has been thought that use of radiation as treatment can cause anaplastic transformation but ?? now
Adenosquamous:
Adenosquamous: glandular/squamous origin. acts like adeno
Glassy cell:
Glassy cell: poor differentiation (adenosquamous)
Clear cell:
Clear cell: poor differentiation. Nodular and reddish in gross appearance. Linked to in-utero DES exposure (Diethylstilbestrol)
Neuroendocrine:
Neuroendocrine: Small cell, large cell, carcinoid
Papillary sq cell:
Papillary sq cell: SCC variant. Looks like transitional or cuboidal cells on microscopy
Mesonephric adeno:
Mesonephric adeno: occasionally see remnants of the mesonephric ducts laterally – PAS +
What immunohistochemistry is associated with HPV
p16 is a surrogate marker for the presence of high-risk HPV.
