Diagnostik und Therapie maligner Ovarialtumoren 2005: Die Empfehlungen der Kommission Ovar der AGO

Report of the survey on current opinions and practice of German Society for Gynecologic Endoscopy (AGE) members regarding the laparoscopic treatment of ovarian malignancies

PURPOSE

The purpose of this survey was to assess the opinions of members of the German Society of Gynecologic Endoscopy (AGE) regarding the laparoscopic treatment of ovarian malignancies and current practice at their institutions.

METHODS

Between February and October 2015, the AGE sent an anonymous online survey via mail to its members. The questionnaire solicited participants' opinions about the laparoscopic treatment of ovarian cancers according to T stage and borderline tumors, and information about current practice at their institutions. Participants were also asked their opinions on currently available data on this issue.

RESULTS

Of 228 AGE members who completed the survey, 132 (58%) were fellows or attending physicians and 156 (68%) worked at university hospitals or tertiary referral centers. Most [212 (93%)] respondents stated that < 10% of all ovarian cancer cases were currently treated laparoscopically at their institutions. Most participants indicated that T1 (a, b, c) tumors [145 (64%)] and ovarian borderline tumors [206 (90%)], but not T2 [48 (21%)] or T3/4 [9 (4%) ovarian tumors] should or could be treated laparoscopically. One hundred seventy-two (75%) participants considered currently available data on this topic to be insufficient and 152 (66%) stated that they would take part in a clinical trial assessing a laparoscopic approach to T1/2 ovarian cancer.

CONCLUSION

According to this survey, to the opinion of the majority of AGE members, laparoscopy might be a considerable option for the treatment of early ovarian malignancies and borderline tumors and should be evaluated further in future studies.

Pattern and clinical predictors of lymph node metastases in epithelial ovarian cancer

Para-aortic lymphadenectomy is part of staging in early epithelial ovarian cancer (EOC) and could be part of therapy in advanced EOC. However, only a minority of patients receive therapy according to guidelines or have attendance to a specialized unit. We analyzed pattern of lymphatic spread of EOC and evaluated if clinical factors and intraoperative findings reliably could predict lymph node involvement, in order to evaluate if patients could be identified in whom lymphadenectomy could be omitted and who should not be referred to a center with capacity of performing extensive gynecological operations. Retrospective analysis was carried out of all patients with EOC who had systematic pelvic and para-aortic lymphadenectomy during primary cytoreductive surgery. One hundred ninety-five patients underwent systematic pelvic and para-aortic lymphadenectomy. Histologic lymph node metastases were found in 53%. The highest frequency was found in the upper left para-aortic region (32% of all patients) and between vena cava inferior and abdominal aorta (36%). Neither intraoperative clinical diagnosis nor frozen section of pelvic nodes could reliably predict para-aortic lymph node metastasis. The pathologic diagnosis of the pelvic nodes, if used as diagnostic tool for para-aortic lymph nodes, showed a sensitivity of only 50% in ovarian cancer confined to the pelvis and 73% in more advanced disease. We could not detect any intraoperative tool that could reliably predict pathologic status of para-aortic lymph nodes. Systematic pelvic and para-aortic lymphadenectomy remains part of staging in EOC. Patients with EOC should be offered the opportunity to receive state-of-the-art treatment including surgery

Ovarian surgery and follicular reserve

In patients with cystic ovarian pathology, such as endometriomas, polycystic ovary syndrome, teratomas or benign tumors, there is a tendency towards abnormal ovarian function. Anovulation and sterility may occur. This review will summarize the normal physiology of the female gonad and the development of oogenesis from initial reproductive age to the menopause. Furthermore, the interaction between ovarian pathology and endocrinology will be described. The main focus is on the technique of ovarian-preserving surgery by laparoscopy. In addition, alternative therapeutic approaches and screening tests will be discussed.

Ovarian cancer-can intraperitoneal therapy be regarded as new standard in Germany?

The German Arbeitsgemeinschaft Gynaekologische Onkologie (AGO) and the two German cooperative study groups (AGO-OVAR and NOGGO) performed a review of the currently available literature on intraperitoneal first-line treatment in advanced ovarian cancer to consider if this new option should be incorporated into the German guidelines for treatment of ovarian cancer.
