Our patient underwent pelvic US (,Fig 20,), which showed a 13.6-mm endometrial echo complex with an irregular endometrial-myometrial interface, inhomogeneous internal echogenicity, and abnormally branching blood vessels, all of which raise suspicion for endometrial carcinoma. Figure 13b. (b) Color Doppler image shows irregular vessels (arrow) within the area of endometrial thickening. Of UEC cases, 34% to 50% contain mutations of PTEN, making it the most commonly mutated tumor suppressor gene in UEC. (b) Photograph shows the vena cava after the removal of lymph nodes. … Infection and bowel issues have significantly improved. The majority of cases were related to inflow obstruction of Tenckhoff catheters, infections, and bowel perforations; inflow obstruction was the most common complication. Endometrioid carcinoma comprises 10% to 20% of ovarian carcinomas and is bilateral in 28% of cases.37 Up to 42% are associated with endometriosis, and 15% to 20% with a coexisting adenocarcinoma of the endometrium.37 Endometrioid carcinomas are usually cystic and solid tumors with foci of necrosis and hemorrhage. (a) Sagittal T2-weighted image, obtained to localize the cervix, shows an imaging plane (dashed lines) that is axial to the cervix. Figure 7. Surgical treatment required lymph node dissection, although selective pelvic and paraaortic lymph node sampling was also allowed; however, there had to be nodes present from each nodal basin. External-beam radiation therapy provides approximately 40–45 Gy, which is approximately half of the required dose for cure. 16.18), exhibits positive nuclear staining for estrogen and progesterone receptors, and does not stain for inhibin or calretinin (Table 16.11).307 In contrast, sex cord-stromal tumors may stain for cytokeratin, but they are negative for EMA and they show cytoplasmic staining for inhibin, and cytoplasmic and nuclear staining for calretinin.201. High-risk features included depth of myometrial invasion, grade 2 or 3 disease, older age, and lymphatic-vascular space invasion. The four mechanisms of spread are intraperitoneal dissemination, direct invasion of adjacent organs, hematogenous spread, and lymphatic spread to locoregional nodes and thence to the aortocaval nodes (,4). Placement with image guidance ensures proper coverage of the tumor volume with minimal dose to the bladder, rectum, and sigmoid (,45) (,Fig 23). For all patients with surgical assessment of lymph nodes, the highest risk of recurrence was in the vaginal cuff. Parametrial extension is best evaluated on images that show a true axial section through the cervix, the so-called doughnut view (,Fig 8,). An argon beam coagulator for small tumor implants can be used on serosal and mesenteric surfaces. ,Figure 10 depicts standard pelvic radiation fields covering the internal and external iliac lymph nodes, which must be treated for postoperative or locally advanced (inoperable) cases. Microscopically they can also simulate granulosa cell tumors, forming trabeculae or solid sheets punctuated by small round openings resembling the Call-Exner bodies of a granulosa cell tumor (Figs. The view is from the right side looking toward the feet. In GOG 172, both hematologic and nonhematologic toxic effects were significantly stronger in the intraperitoneal arm. Because the differential diagnosis for an adnexal mass is broad, an important role for the radiologist is recognition of benign entities such as a hemorrhagic cyst. Fluorodeoxyglucose PET is very useful in the diagnostic and staging work-up of cervical cancer. Purpose. Figure 11. The disease can occur in the tissue on the outside of the womb, but most uterine cancers start in its inner lining, in the cells that produce mucus and other fluids. Prior studies generally were retrospective and had potential limitations, including use of self … Complications of brachytherapy result from a very high dose being delivered to a very small volume of tissue and may include bleeding, ulceration, and fistula.

Improper placement of a radiation therapy applicator. Studies of preoperative sensitivity and specificity indicate that PET may be more accurate than MR imaging in diagnosis of cervical cancer (,25). “Her lifetime chance of dying from ovarian cancer is about 1 in 100.”, After the ovaries, the next stop for eggs before the uterus is the fallopian tubes, another body part that can have cancer. Although removing the uterus may stop the cancer while it’s in its early stages, if left untreated it may spread to the cervix, which is the passageway to the vagina, and then to other body parts. The National Cancer Institute links cancer in the tubes to that of the ovaries, also making it one of the deadliest cancers. A randomized trial of brachytherapy alone comparing four and six fractions showed that six fractions decreased the rate of vaginal stenosis (,41). US was used to reposition the tandem into the center of the uterine canal. As with other imaging in gynecologic oncology, good technique is vital. The view is from the right side looking toward the feet. The superior soft-tissue contrast of MR imaging makes it preferable to CT for this indication. Intraperitoneal dissemination produces a shower of malignant cells that implant on the omentum as well as on the serosa of the liver, spleen, and bowel. Low-dose-rate radiation therapy typically requires inpatient hospitalization, whereas high-dose-rate radiation may be given over several outpatient visits (,24). A 65-year-old woman presented to her family practitioner with the complaint of abdominal bloating. Table 1.Evidence for the Effectiveness of Intraperitoneal Chemotherapy. Improper placement of a radiation therapy applicator. Endometrioid carcinoma of the ovary must have at least one of the following characteristics: glands typical of endometrioid adenocarcinoma, foci of squamous differentiation, and/or an adenofibromatous component [35]. Radiologists need to be aware of the ways in which ovarian cancer spreads in order to recognize extensive disease and provide helpful staging information to oncologists and surgeons. It might be detected with routine pelvic exams and, if found early, is often curable. Future advances in image-guided evaluation and treatment may ultimately increase patient survival. The addition of imaging-guided interstitial brachytherapy after external-beam therapy results in sparing of the bladder, rectum, and sigmoid colon. Epidemiologic studies have consistently found two- to threefold increases in the risk of ovarian ECs in patients with endometriosis. 19.24 and 19.25).8,108 If positive (or globally negative), we classify these tumors as high-grade endometrial carcinomas of uncertain type, and note that this decision is based on the unusual pattern combined with the p53 immunophenotype.12,13, J. Bergstrom, ... A.N. Correct imaging plane for evaluation of cervical cancer with MR imaging. Contrast-enhanced CT scan shows an extensive omental “cake,” mesenteric nodularity, and ascites.
