  1. Third most common gynecologic cancer diagnosis in the US
    Cervical cancer
  2. 80% of cervical cancer cases are classified as
    squamous cell
  3. is the second most common subtype and counts for 15% of cases; (gynecologically)
    Adenocarcinoma
  4. central to the development of both aforementioned subtypes(cervical cancer amd adenocarcinoma)

  8. Four major steps in the development of cervical cancer:
    • Oncogenic HPV infection at junction of vaginal portion of cervix and cervical canal
    • HPV infection
    • Progression to precancer
    • carcinoma and invasion into membrane

    sporadic breast cancer
  22. Factors related to hormone exposure causing breast cancer include
    gender, age at menarche and menopause, reproductive history, breastfeeding, and exogenous estrogen
  23. Researchers believe that breast cancer begins to form when
    the cells in the milk-producing ducts grow uncontrollably and rapidly
  24. What causes fibrocystic changes in breast
    changes during puberty allow stromal and ductal components to deviate from their normal development
  25. What age does involution occur (breast cancer)
    35 years
  26. involutional changes occur which involves (breasts)
    the replacement of loose hormone receptive connective tissue with denser connective tissue in the stroma
  27. Invasive ductal carcinoma – three major genetic pathways
    • ER-positive and HER2-negative
    • HER2-positive
    • ER-negative and HER2 negative
  28. Germline mutation in TP53 that causes HER2 amplification leads to
    atypical apocrine adenosis which is known as a putative precursor lesion
  29. HER2-positive Strongly associated with strengthening of
    HER2 gene on chromosome 17q
  30. Lesions can progress to ductal carcinoma in situ caused by
    angiogenesis and tumor-associated inflammation
  31. Fibrocystic changes – principal variations include
    cysts, fibrosis, adenosis, and mild ductal and lobular hyperplasia
  32. Cysts in breasts form due to
    dilation of lobules, may be small but can come together and form larger cysts
  33. Palpable nodules of the breast are due to
    fibrosis
  34. Increased acini per lobule
    adenosis

    line milk duct and spread to nearby tissue

    3g
  51. principle urinary protein that is excreted in NS
    albumin
  52. Increased amounts of protein in the urine diminishes...resulting in
    • serum albumin levels faster than the liver can compensate for
    • hypoalbuminemia causing edema
  53. dense deposits of immune complexes such as Ig in NS is a characteristic finding of
    membranous nephropathy
  54. As nephrotic syndrome advances in severity, glomeruli may become
    totally sclerosed.
  55. Sclerosed segments of glomeruli causes
    collapse of capillary loops leads to an increase in matrix and segmental accumulation of plasma proteins along the capillary wall, also known as hyallosis
  56. NS key manifestations are
    proteinuria, hypoalbuminemia, generalized edema, hyperlipidemia, and lipiduria; pleural effusions and ascites may be noted in severe cases; NS causes a hypercoagulable state

    Endometrial carcinoma
  58. endometrial cancer hyperplasia is caused by
    unopposed estrogen and lack of progesterone
  59. continuous estrogen stimulation unopposed by progesterone is caused by inactivation of the
    tumor suppressor gene PTEN
  60. what percent of cases of endometrial cancer uses atypical hyperplasia state caused by mutations in KRAS gene
    40%
  61. rarely progress to adenocarcinoma but may turn into cystic atrophy when estrogen is withdrawn
    Non-atypical hyperplasia
  62. at times cannot be discerned from well-differentiated endometrioid adenocarcinoma until a hysterectomy is complete
