To determine the effectiveness of annual gynaecological screening (pelvic examination, transvaginal ultrasound, and CA-125), a prospective cohort study of women at high risk for hereditary ovarian cancer was conducted. Women were offered DNA analysis followed by either annual screening or prophylactic bilateral salpingo-oophorectomy (BSO). Study population consisted of 512 highrisk women (median follow-up 2.07 years, range 0 -9.4 years): 265 women (52%) had a BRCA mutation. Persisting abnormalities indicated diagnostic surgery in 24 women resulting in one primary ovarian cancer FIGO stage IIIc was found. The effectiveness of screening was studied by calculating the probability of finding ovarian cancers in the BRCA-1 and BRCA-2 carrier group and comparing this to the identified number of ovarian cancers. The number of ovarian cancer patients found at surveillance was in accordance with the predicted number of ovarian cancers. A total number of 169 women underwent prophylactic BSO: one ovarian cancer stage IIb was found. In conclusion, the surveillance programme for hereditary ovarian cancer does identify patients with ovarian cancer but is very inefficient considering the high number of surveillance visits and the advanced stage of ovarian cancer in the identified patient. For prevention of advanced stage ovarian cancer, prophylactic BSO from age 35 -40 years is a more efficient alternative.

In case of an ovarian tumor, metastatic disease should always be considered to avoid pitfalls in diagnosis and therapy. The gastrointestinal tract is the most likely location of the primary tumor, followed by breast and endometrium.

In women with hereditary non polyposis colorectal carcinoma (HNPCC) an annual gynaecological surveillance has been recommended because of an increased lifetime risk of developing endometrial and ovarian carcinoma. The aim of this study was to assess the efficacy of gynaecological surveillance with regard to endometrial and ovarian carcinoma. Included were women from families that fulfilled the revised Amsterdam criteria for HNPCC or who showed a proven mutation in one of the mismatch repair genes. An annual gynaecological surveillance was performed (transvaginal ultrasound (TVU) and CA 125 assessment). From January 2006 on, routine endometrial sampling was included. In a total number of 100 women 285 surveillance visits were performed. Among these, in 64 visits routine endometrial samplings were performed: three atypical hyperplasias and one endometrial carcinoma were diagnosed. This was significantly more than the atypical hyperplasia and two endometrial carcinomas that were detected after 28 samples performed because of abnormal surveillance results in 221 visits. There were no interval carcinomas. One invasive ovarian carcinoma stage IIIC was diagnosed at ovarian surveillance. Endometrial surveillance with routine endometrial sampling in women with HNPCC is more efficient in diagnosing endometrial (pre)malignancies than TVU only. Ovarian surveillance is not capable of diagnosing early stage ovarian carcinoma. Prophylactic hysterectomy in HNPCC should be restricted to women in whom abdominal surgery for other reasons is performed and to those with particularly increased risk such as MSH6 mutation carriers and/or women with multiple relatives with endometrial carcinoma.

This study analyzes the site of disease recurrence in ovarian cancer patients to assess the influence of a single intraperitoneal (IP) administration of yttrium-90-labeled murine monoclonal antibody HMFG1 ( 90 Y-muHMFG1) on the pattern of disease recurrence. In a large phase III trial ovarian cancer patients in complete clinical remission with FIGO stage Ic-IV were randomized between standard treatment plus a single IP 90 Y-labeled muHMFG1 versus standard treatment alone after negative second-look laparoscopy. Case report forms of all patients with disease recurrence were reviewed to determine site and date of recurrent disease. In total 447 patients were included in the study with a median follow-up of 3.5 years. Relapse was seen in 104/224 in the active and 98/223 in the control arm. Significantly fewer IP (p < 0.05) and more extraperitoneal (p < 0.05) relapses occurred in the active treatment arm. Time to IP recurrence was significantly longer (p 5 0.0019) and time to extraperitoneal recurrence was significantly shorter for the active treatment arm (p < 0.001). The impact of IP radioimmunotherapy on IP relapse-free survival could only be seen in the subgroup of patients with residual disease after primary surgery (HR, 0.31; 95% CI, 0.18 to 0.53; p 5 0.002). Although, there is no survival benefit for IP radioimmunotherapy as consolidation treatment for epithelial ovarian cancer, we found an improved control of IP disease, that was offset by increased extraperitoneal recurrences. ' 2007 Wiley-Liss, Inc.Key words: HMFG1; intraperitoneal; ovarian cancer; yttriumThe prognosis of women with advanced stage ovarian cancer remains poor despite 40 years of research into systemic therapies. Epithelial ovarian cancer is the fifth leading cause of cancer deaths and the most lethal gynecologic cancer in the United States.1 The introduction of platinum and subsequently taxane based chemotherapy has resulted in longer progression free (15.5-22 months) and overall (31-44 months) survivals, yet at least 50-75% of these women have persistent or recurrent disease with long-term survival (>5 years) achieved in only 25%. 2,3 In the majority (82%) of the patients recurrence is seen within the peritoneal cavity, and in 12% it occurs in the retroperitoneal lymph nodes. 4,5 The rationale for intraperitoneal (IP) therapy in ovarian cancer is based on the predominately or solely peritoneal location of ovarian cancer during the early part of the natural history of the disease and the significant pharmacologic advantage of delivering antitumor agents directly into the accessible but confined space of the peritoneal cavity. Three randomized trials in ovarian cancer patients affirmed this assumption by demonstrating improved survival with IP chemotherapy as compared to similar or identical agents delivered systemically. [6][7][8] Recently, the National Cancer Institute proposed to make IP chemotherapy part of the standard treatment in ovarian cancer.

Background Double-layer compared to single-layer closure of the uterus after a caesarean section (CS) leads to a thicker myometrial layer at the site of the CS scar, also called residual myometrium thickness (RMT). It possibly decreases the development of a niche, which is an interruption of the myometrium at the site of the uterine scar. Thin RMT and a niche are associated with gynaecological symptoms, obstetric complications in a subsequent pregnancy and delivery and possibly with subfertility. Methods Women undergoing a first CS regardless of the gestational age will be asked to participate in this multicentre, double blinded randomised controlled trial (RCT). They will be randomised to single-layer closure or double-layer closure of the uterine incision. Single-layer closure (control group) is performed with a continuous running, unlocked suture, with or without endometrial saving technique. Double-layer closure (intervention group) is performed with the first layer in a continuous unlocked suture including the endometrial layer and the second layer is also continuous unlocked and imbricates the first. The primary outcome is the reported number of days with postmenstrual spotting during one menstrual cycle nine months after CS. Secondary outcomes include surgical data, ultrasound evaluation at three months, menstrual pattern, dysmenorrhea, quality of life, and sexual function at nine months. Structured transvaginal ultrasound (TVUS) evaluation is performed to assess the uterine scar and if necessary saline infusion sonohysterography (SIS) or gel instillation sonohysterography (GIS) will be added to the examination. Women and ultrasound examiners will be blinded for allocation. Reproductive outcomes at three years follow-up including fertility, mode of delivery and complications in subsequent deliveries will be studied as well. Analyses will be performed by intention to treat. 2290 women have to be randomised to show a reduction of 15% in the mean number of spotting days. Additionally, a cost-effectiveness analysis will be performed from a societal perspective. Discussion This RCT will provide insight in the outcomes of single- compared to double-layer closure technique after CS, including postmenstrual spotting and subfertility in relation to niche development measured by ultrasound.
