Gyn-Onc Flashcards
What is the preferred route of hysterectomy for benign conditions when patient factors and surgeon experience permit
Vaginal Hysterectomy.
Ex: 57 yo P3 with 11wk uterus and single 7 cm fundal fibroid.
Management of AGC (Atypical Glandular Cells) on pap
-AGC: represent < 1% of pap tests , previously known as AGUS
-4 Categories when result is AGC
1. AGC: endocervical, endometrial or not specified
2. AGC: Favor neoplastic-endocervical or not specified
3. Endocervical adenocarcinoma in situ
4. Adenocarcinoma
-Evaluation:
1. ALL receive colposcopy
2. Endocervical sampling EXCEPT atypical endometrial cells
3. EMB IF
-35 years and older
-Less than 35 IF increased risk of endometrial neoplasia (AUB/Annovulation)
Statistics: Sensitivity
Proportion of subjects with the disease who are correctly identified by a positive test
Calculation: (subjects with disease and a positive test) / (total with the disease)
or a/(a+c)
Statistics: Specificity
Proportion of subjects withOUT the disease who are correctly identified by a negative test
Calculation: (subjects without disease and negative test) / (total without disease)
or d (b+d)
Statistics: PPV or Positive Predictive Value
Proportion of subjects with positive result who actually have the disease
Calculation: True positive (disease pos and test pos) / total positive results
a / (a+b)
*Varies by prevalence of disease. PPV decreases with low prevalence as false positive results increase. Difficult to develop accurate screening tests for diseases with low prevalence
Statistics: NPV Negative Predictive Value
Proportion of subjects with negative test who do not have the disease
Calculation: True negative / total negative results
d/ (d+c)
Treatment of uterine carcinosarcoma
In patients with advanced stage chemotherapy is indicated
Side Effects of Cytotoxic Chemotherapy
-Bone marrow toxicity
-Therapy parameters. If no delay therapy until recovery
1. Granulocytes (day of therapy) < 1500
2. Plts (day of therapy) < 75K
3. Granulocytes (cycle nadir) < 1000
4. Plts (cycle nadir) < 50K
Pseudomyxoma Peritonei. What is the primary tumor site
-Abundant collection of gelatinous material in abdomen
-Primary site: GI. Specifically Appendix
-Mucinous tumor of ovary seconday
Management of IDA in patient undergoing chemotherapy
Defined as Ferritin < 30
-Replace Iron stores.
-Avoid Erythropoietin stimulating agents as may progress disease
What tumor site are CEA and CDX2 associated with
GI Tumors
Goals of Hospice Care
Providing palliative care, symptom management and quality of life improvement
Qualify if ~ last 6 mo of life
Management of Immature Teratoma
-Ovarian germ cell tumors account for 2-3% of all cases of ovarian cancer in Western countries
-Typically in women in 20s
-No Chemo indicated for immature teratomas that are Stage 1/Grade 1 vs. could consider in Grade 2/3 (more nueral elements)
-MOST Germ Cell Tumors: Chemo with Bleomycin, Etoposide and Cisplatin
Toxicities:
1. Bleomycin: Pulmonary Fibrosis
2. Etoposide: Secondary Heme Malignancy
3. Cisplatin: Neuropathy
Management of Hyperkalemia
-Diagnosis: K > 6.0 or Less with EKG changes (peaked T waves)
-Treatment
1. IV Calcium: Stabilizes the myocardium
2. Insulin and Glucose: Drives K into cells
3. Diuretics: Remove K
