  1. List three categories of organs in the female reproductive system and give examples of each.
    • 1)Primary: Ovaries
    • 2)Internal Accessory:fallopian tubes, uterus, vagina
    • 3)External:(the vulva) labia majora, labia minora, clitoris, vestibule, and vestibular glands
  2. Describe the Ovaries, give their location and state where lymph drainage from the ovaries goes.
    The ovaries are solid, ovoid structures the size of unshelled walnuts and are located on the lateral walls of the pelvic cavity(one on either side). Lymphatic drainage goes almost exclusively to the pariaortic lymph nodes(lumbar chain of nodes).
  3. Locate and describe the broad, suspensory and round ligaments.
    • 1)The largest of the ligaments is is the broad ligament which is formed by a fold of peritoneum. It is attached to the fallopian tubes and uterus.
    • 2)The ovary is held in place at the upper endĀ  by a small fold of peritoneum called the suspensory ligament. The suspensory ligament contains ovarian blood vessels and nerves.
    • 3)A flattened band of tissue within the broad ligament,called the round ligament, connects the upper end of the uterus to the pelvic wall.
  4. State the function of the uterine tubes and give another name for them.
    Uterine tubes, also called fallopian tubes, convey egg cells toward the uterus.
  5. Describe the infundibulum and the fimbriae of the uterine tube.
    Near the ovary, the fallopian tube expands to form a funnel shape called a infundibulum.The infundibulum bears a number of irregular, branched, extensions, called fimbriae.Although the infundibulum does not generally touch the ovary, the fimbriae are directly connected to it.
  6. Describe how the movement of the egg from the ovary to the uterus if accomplished.
    Transport of the ovary to the uterus is facilitated by the uterine tube cilia, which sweep the egg towards the uterus. In addition, peristaltic contraction help force the egg along.
  7. Describe the uterus and state its function
    The uterus, whose function is to receive the embryo and sustain its life during development, is a hollow, muscular organ shaped somewhat like a pear.
  8. State the significance of the retrouterine pouch.
    A posterior ligament forms a deep pouch between the uterus and rectum. This pouch helps prevent the spread of uterine cancer to the rectum.
  9. Describe and locate the parts of the uterus, including the: fundus, body, corpus, cervix, internal os, external os.
    The upper 2/3 of the uterus is the body or corpus and has a dome shaped top and is joined by uterine tubes that enter its wall. The fundus is the rounded portion above the entrance of the uterine tubes. The junction of the uterine cavity is the the cervical canal is called the internal os. The lower end of the cervical canal opens into the vagina and is termed the external os. The cervix surrounds the opening through which the uterus communicates with the vagina.
  10. Describe the location of the vagina and identify the following parts: vault, fornices.
    The vagina is located posterior to the urinary bladder and urethra and anterior to the rectum. The part of the vagina that surrounds the cervix is known as the vault and the recesses that occur between the vaginal wall and the cervix are termed fornices.
  11. List the structures that make up the vulva:
    labia major, labia minor, clitoris, vestibule, and vestibular glands
  12. Discuss the importance of early screening methods for gynecologic cancers.
  13. State what tool is most effective for early screening methods for gynecologic cancers.

  16. List the risk factors for cancer of the cervix and give the peak age of incidence.
    • Peak age 50-60
    • lower socioeconomic status(lack of health care)
    • Early sexual activity, multiple partners, and multiple pelvic infections(HPV, herpes, and genital warts)
    • DES daughters
    • Smoking
  17. State the most common method of spread for cancer of the cervix.
    Direct extension-uterus, vagina, bladder, rectum
  18. Describe the pattern of lymphatic spread usually followed by cancers of the cervix.
    • Lymph nodes are orderly:
    • paracervical, parametrial, pelvic, common iliac, para-aortic, and even SCV nodes
  19. List some common metastatic sites for cervical cancer.
    lungs, bone, liver
  20. Discuss and describe pap smear classification, class I-class IV
    • Class I-Normal
    • Class II-atypical
    • Class III-dysplasia
    • Class IV-carcinoma in situ
  21. Describe a complete diagnostic workup for cervical cancer.
    H&P including pelvic and rectal exams, CT, MRI, PET, cystoscopy, and proctoscopy are used to asses metastastic disease.
  22. List the most common symptoms of carcinoma of the cervix.
    postcoital bleeding, increased menstrual bleeding, discomfort with intercourse, *malodorous discharge, pelvic pain, and urinary or rectal pain may accompany more advanced disease
  23. List factors upon which clinical staging is based
    How far the cancer has extended-
  24. Discuss and describe the staging for cancer of the cervix.
    • Tis-Carcinoma in situ
    • T1-Confined to Cervix
    • T2-Extenion into the vagina upper 2/3/parametrium
    • T3-Extension into lower 1/3 of vagina/parametrium/pelvic wall
    • T4-extension to bladder/rectum/beyond true pelvis
  25. Discuss the two primary treatments for cervical cancer.
    • TAH with a small amount of vaginal tissue called a cuff(or even more for later stages)
    • and
    • RT-Tandem and Ovoid implant
  26. Discuss the the treatment fr precancerous lesions of the cervix.
    The cervix is viewed with a colposcope and any suspicoius areas are biopsied. The precancerous areas are removed with a laser or cryosurgery.
  27. Discuss internal vs. external radiation for cervical cancer.
    • internal radiation only is used when not trying to cover lymph nodes. Early stages-1a1-1a2: are treated with a TAH OR brachy(tandem and ovoids.
    • Stage 1b1 and 2a:are treated with a choice of TAH or external beam RT(for nodes) AND and implant.
    • Stage 2b-4: RT and Chemo because the cancer has spread there is no need to do a TAH. RT treats the pelvis and chemo treats systemically to get any disease that has spread.
  28. Describe the external RT port for cervical cancers.
    • 4 field box
    • Border AP/PA
    • -Top-L4-L5
    • -Bottom-Below obturator foramen unless the vagina is involved then 4 cm below
    • -Lateral-2cm lateral to pelvic side walls

    • Borders Lats
    • -Top and bottom same as above
    • -Anterior at pubic symphysis
    • -Posterior includes S3
  29. Describe an afterloading system
    Low dose brachytherapy using Cesium where the physicist or the RT loads the source into the tandem and ovoids/etc.
  30. Define tandem, ovoids, colpostats, give the purpose and positioning of each. Also give the three sizes of ovoids.
    • The tandem is a curved rod that is inserted into the uterus, and the ovoids/colpostats(different manufactures call them different things) are the hemispherical pieces that flank the cervix in the fornices. Ovoids are one pieceĀ  and look like golf clubs. The colpostats are the hemispherical pieces that fit on the end of the rod.(so each side has 2 pieces unlike the ovoids)They are used to administer brachytherapy
    • Ovoids,basically come in sizes S,M,L
  31. Describe the Manchester System, locate point "A" and point "B" and state what each point represents.

    The Manchester system is either a ring and ovoids or tandem and oviods used for brachytherapy of the cervix or uterus.Point A-2cm superior and 2 cm lateral to the external os-associated with dose to the uterusPoint B- 2 cm superior and 5 cm lateral to the external os-associated with dose to the nodal areas

    • Endometrial:TAH, brachy and external beam RT added for later stages.
    • Stage 3-4-external beam RT alone
    • Ovarian:Surgery is main mode of treatment, chemo is also used. RT for mets and palliation
    • Vaginal-RT is treatment of choice for AP/PA fields. For superficial lesion-brachy 60 Gy.Deeper lesions -whole pelvis external beam RT 45-50Gy boosted and vagina boosted with brachy 65-80Gy
