Background
The increasing role of robotic surgery in gynecologic oncology may impact fellowship training. The purpose of this study was to review the proportion of robotic procedures performed by fellows at the console, and compare operative times and lymph node yields to faculty surgeons.Methods
A prospective database of women undergoing robotic gynecologic surgery has been maintained since 2008. Intra-operative datasheets completed include surgical times and primary surgeon at the console. Operative times were compared between faculty and fellows for simple hysterectomy (SH), bilateral salpingo-oophorectomy (BSO), pelvic (PLND) and paraaortic lymph node dissection (PALND) and vaginal cuff closure (VCC). Lymph nodes counts were also compared.Results
Times were recorded for 239 SH, 43 BSOs, 105 right PLNDs, 104 left PLNDs, 34 PALND and 269 VCC. Comparing 2008 to 2011, procedures performed by the fellow significantly increased; SH 16% to 83% (p < 0.001), BSO 7% to 75% (p = 0.005), right PLND 4% to 44% (p < 0.001), left PLND 0% to 56% (p < 0.001), and VCC 59% to 82% (p = 0.024). Console times (min) were similar for SH (60 vs. 63, p = 0.73), BSO (48 vs. 43, p = 0.55), and VCC (20 vs. 22, p = 0.26). Faculty times (min) were shorter for PLND (right 26 vs. 30, p = 0.04, left 23 vs. 27, p = 0.02). Nodal counts were not significantly different (right 7 vs. 8, p = 0.17 or left 7 vs. 7, p = 0.87).Conclusions
Robotic surgery can be successfully incorporated into gynecologic oncology fellowship training. With increased exposure to robotic surgery, fellows had similar operative times and lymph node yields as faculty surgeons. 相似文献2.

STUDY OBJECTIVE: Cervical cancer is a significant health problem in countries of the developing world. Although case series suggest advantages of total laparoscopic radical hysterectomy (TLRH) compared with total abdominal radical hysterectomy (TARH), no randomized controlled trial is currently available to establish TLRH as the new standard treatment. In this study, TLRH or total robotic radical hysterectomy (TRRH) will be performed without a vaginally assisted portion of the procedure. DESIGN: A biphasic randomized controlled trial was designed to test feasibility of recruitment and equivalence in regard to disease-free survival (Canadian Task Force classification I). SETTING: Tertiary referral hospital. PATIENTS: Patients with histologically confirmed invasive squamous cell carcinoma or adenocarcinoma of the cervix, stage IA1 (with lymphovascular space invasion), IA2, and IB1 are eligible. INTERVENTIONS: During the first phase, 100 patients will be randomized (1:1) to receive either TLRH/TRRH or TARH, with the primary end point being the rate of enrollment. During the second phase, recruitment will be extended by another 640 patients in a 1:1 TLRH/TRRH:TARH allocation, to determine equivalence with respect to disease-free survival with 80% power and alpha=0.05. MEASUREMENTS AND MAIN RESULTS: Equivalence will be assumed if the difference in disease-free survival does not exceed 7% at 4 years. Secondary outcomes include treatment-related morbidity, costs and cost effectiveness, patterns of recurrence, quality of life, pelvic floor function, feasibility of intraoperative sentinel node sampling, and overall survival. All data from this multicenter study will be entered using online electronic case report forms, allowing real-time assessment of data completeness and patient follow-up. CONCLUSION: This prospective trial aims to show the equivalence of a TLRH/TRRH versus TARH approach for patients with early stage cervical cancer following a 2-phase protocol. This trial was developed and designed with the input and approval of the members of the Gynecologic Oncology Committee from the American Association of Gynecologic Laparoscopists. 相似文献

BACKGROUND: Although cervical cancer is clinically staged, surgery has long been considered the best means to assess extrapelvic disease and remains the gold standard for the detection of both intraperitoneal spread and small volume nodal metastases. The objective of this study was to determine short- and long-term outcomes for patients with locally advanced cervical cancer who underwent pretherapeutic laparoscopic staging. METHODS: From 1997 to 2004, 184 patients with stages IB2-IVA cervical cancer underwent pretherapeutic laparoscopic staging procedure including transperitoneal abdomino-pelvic exploration and extraperitoneal bilateral infrarenal paraaortic lymph node dissection. Patients were then treated with definitive radiotherapy tailored according to the staging results. RESULTS: The median age and BMI were respectively 45.8 years old and 27.1 kg/m2. Most lesions were squamous (n=172) and clinical stage was evenly distributed. Median operative time was 155 min with an average of 20.8 lymph nodes removed. Postoperative hospital stay averaged 1.4 days. Major complications included 1 intraoperative ureteral injury and 1 postoperative bowel obstruction from an umbilical trocar site hernia. The final pathology revealed that 44 patients (24.3%) had metastatic disease within paraaortic lymph nodes. With a median follow-up of 26.8 months (average 32.9), 67 patients (36.4%) had recurrent disease. Overall 5-year survival rate was 58.3%. Successful resection of positive lymph node correlated with a survival advantage. CONCLUSIONS: Pretherapeutic laparoscopic assessment of patients with locally advanced cervical cancer offers valuable information for individualized treatment planning with minimal morbidity. This appears to be a therapeutic effect with resection of positive nodes followed by a tailored chemoradiation therapy. 相似文献

Study Objective
To compare the accuracy of frozen section diagnosis of borderline ovarian tumors among 3 distinct types of hospital—academic hospital with gynecologic pathologists, academic hospital with nongynecologic pathologists, and community hospital with nongynecologic pathologists—and to determine if surgical staging alters patient care or outcomes for women with a frozen section diagnosis of borderline ovarian tumor.Design
Retrospective study (Canadian Task Force classification II-1).Setting
Tertiary care, academic, and community hospitals.Patients
Women with an intraoperative frozen section diagnosis of borderline ovarian tumor at 1 of 3 types of hospital from April 1998 through June 2016.Interventions
Comparison of final pathology with intraoperative frozen section diagnosis.Measurements and Main Results
Two hundred twelve women met the inclusion criteria. The frozen section diagnosis of borderline ovarian tumor correlated with the final pathologic diagnosis in 192 of 212 cases (90.6%), and the rate of correlation did not differ among the 3 hospital types (p?=?.82). Seven tumors (3.3%) were downgraded to benign on final pathologic analysis and 13 (6.1%) upgraded to invasive carcinoma. The 3 hospital types did not differ with respect to the proportion of tumors upgraded to invasive carcinoma (p?=?.62). Mucinous (odds ratio, 7.1; 95% confidence interval, 2.1–23.7; p?=?.002) and endometrioid borderline ovarian tumors (odds ratio, 32.4; 95% confidence interval, 1.8–595.5; p?=?.02) were more likely than serous ovarian tumors to be upgraded to carcinoma. Only 88 patients (41.5%) underwent lymphadenectomy, and only 1 (1.1%) had invasive carcinoma in a lymph node.Conclusions
A frozen section diagnosis of borderline ovarian tumor correlates with the final pathologic diagnosis in a variety of hospital types. 相似文献7.

OBJECTIVE: To evaluate fundal injection of blue dye and radiocolloid for lymphatic mapping and sentinel node identification in women with high-risk endometrial cancer. METHODS: At laparotomy, 18 women with high-risk endometrial cancer had isosulfan blue and technitium-99 radiocolloid injected into the uterine fundus subserosally. Sentinel nodes were then identified either by direct observation of blue dye, by radioactive counts using a handheld gamma counter, or by a combination of both methods. The number and location of sentinel node(s) were recorded and compared with the final lymph node specimens after hysterectomy and selective lymphadenectomy. RESULTS: A sentinel node was identified in only 8 (45%) of the cases. Four patients had sentinel nodes only in the pelvis, 2 had sentinel nodes in the pelvis and above the bifurcation of the aorta, and 2 patients had sentinel nodes above the bifurcation of the aorta only. Seven (88%) patients had unilateral drainage of dye and the radiocolloid; the other patient had bilateral drainage. No patients had metastatic disease to sentinel or nonsentinel lymph nodes. CONCLUSIONS: Subserosal fundal injection of blue dye and the radiocolloid is a poor technique for identifying sentinel lymph nodes in patients with high-risk endometrial cancer. 相似文献

Over several years, it has been a matter of debate whether or not the use of a uterine balloon manipulator during laparoscopic hysterectomies for endometrial carcinoma (EC) may cause tumor disruption resulting in a positive peritoneal cytology. More recently, this procedure has been associated with vascular pseudoinvasion in cases of low-risk EC. In this study, we evaluated a series of 21 cases of low-risk EC treated by laparoscopic hysterectomy (LH) to determine the incidence of this finding and to better characterize its histopathologic features. In addition, we reviewed 28 cases of low-risk EC treated by total abdominal hysterectomy (TAH) for comparison. Clinical information was obtained from patients' charts. Hematoxylin and eosin-stained slides were retrospectively reviewed in all cases. The following information was recorded: tumor grade and tumor stage according to the International Federation of Gynecology and Obstetrics, tumor shape (polypoid versus flat), presence or absence of vascular space involvement (VSI), size and location of the vessels with tumor involvement, concomitant presence of artifactual clefts in the myometrium with tumor involvement if applicable, presence or absence of lymph node sampling and the presence or absence of involvement at this site, and results of peritoneal cytology. Seven of 21 (33%) cases of low-risk EC treated by LH in this study showed VSI. None of the cases treated by TAH had VSI (P=0.001). In all of the cases of LH with VSI, the endometrial tumor was polypoid. VSI was detected only in large, thick-walled vessels in the outer myometrium or in ectatic vessels anywhere in the myometrium; no tumor fragments were seen in small vessels. The tumor in the VSI consisted of conspicuous fragments of tumors detached from the vascular wall. The VSI also lacked the inflammatory perivascular infiltrate seen in many cases of bona fide lymphovascular invasion. In addition, all of the cases with VSI also showed fragments of tumor in artifactual clefts in the myometrium. None of the cases of LH in which lymph node sampling and/or peritoneal cytology were obtained showed tumor at this site. In summary, our study confirms that LH is indeed associated with a higher rate of vascular pseudoinvasion when compared with TAH. However, we cannot attribute this phenomenon to mechanical disruption, displacement, and transport of tumor tissue into vascular spaces by the use of a uterine manipulator alone. Instead, we propose that pathologists may be generating postoperative pseudoinvasion by mechanically transporting tumor into vascular spaces during the grossing process. Proper recognition of this artifact is of utmost importance to avoid the overtreatment of patients undergoing LH for low-risk EC. 相似文献

Recruitment and screening policies and procedures used to establish a paid donor oocyte registry 总被引:3,自引:2,他引:1
We have reviewed the demographic characteristics of, and report
abnormalities noted in, the de-novo growth and development of a paid oocyte
donation programme. The personal profiles of all prospective oocyte donors
were reviewed. Acceptance or rejection of candidates was based upon
screening the results of medical, genetic and psychological testing. A
total of 603 candidates initially responded to our advertisement. From this
pool, 313 individuals were considered suitable and contacted by telephone.
Following further conversation, 176 women were scheduled an entry
interview. On completion of the formal screening process, 17.6% (n = 31) of
those actually interviewed were denied entry. Thus, from the initial
interested parties, only 23% of women wishing to participate in oocyte
donation were considered suitable candidates. Given the high attrition
rate, we concluded that the need for rigorous and thorough medical,
psychological and genetic testing is mandatory for the establishment of a
donor registry. Furthermore, professional counselling of prospective donors
with respect to the results of tests and the implications of test results
with respect to their future medical and reproductive health, are important
parts of providing comprehensive care.
