ABSTRACT

OBJECTIVE: The aim was to systematically review the characteristics of ovarian cancer in women with Lynch syndrome (LS) and evaluate the role of surveillance in detection of ovarian cancer in LS. METHODS: All studies between 1979 and 2015 of women with ovarian cancer and LS or at 50% risk of LS were evaluated. Two reviewers independently evaluated eligible studies and extracted data on age at diagnosis, histological type, FIGO stage, and way of detection according to pre-specified criteria. The studies were assessed for quality using the Newcastle-Ottawa quality assessment scales. RESULTS: The quality score of the 49 identified studies was at least 6 out of 8 and provide clinical information on 747 LS women with ovarian cancer. The mean age at diagnosis was 45.3 (range 19-82) years. Most frequent mutations were MSH2 (47%) and MLH1 (38%). Histopathological data were available for 445 women. The most frequently reported histological type was mixed type (mucinous/endometrioid/clear cell carcinomas) (n = 136; 31%). Most tumours (281, 65%) were diagnosed at an early stage (FIGO I/II). Six studies evaluating the effect of surveillance of ovarian cancer, reported that seven of 22 (32%) ovarian cancers were found during surveillance, 6/7 (86%) were detected at an early stage. CONCLUSION: This systematic review describes that ovarian cancer in women with LS has a wide age-range of onset, is often diagnosed at an early stage with frequently endometrioid/clear cell histology. Data about the role of surveillance in detection of ovarian cancer in women with LS are scarce however detection at an early stage seems possible.

ABSTRACT

Background. Laparoscopic hysterectomies are increasingly popular; a morcellation device is often used. Although there are some clear benefits, morcellation of tissue does have potential risks. Case Presentation. In this case report we present a 55-year-old woman with an abdominal tumour 4 years after a laparoscopic hysterectomy using a morcellation device. Postoperative histological analysis, compromised by morcellated tissue, showed benign myoma. Because of the benign tumour no follow-up was performed. The patient presented now with an abdominal tumour, and she was scheduled for surgical removal of the tumour. During abdominal surgery the tumour appeared malignant and biopsies were taken. Histological analysis showed leiomyosarcoma, and the patient was referred to a third care centre for further treatment. The patient recovered quickly after abdominal removal of the tumour; however, after 7 months the patient had complaints and a CT scan showed a large intra-abdominal tumour with possible lung metastasis. The patient received palliative chemotherapy and died after 10 months. Conclusion. This case shows that although unexpected after a hysterectomy, a leiomyosarcoma has to be considered in case of a suspect tumour in the lower abdomen.

ABSTRACT

OBJECTIVE: Based on previous studies, standard gynecological screening consisting of annual transvaginal ultrasonography (TVU) was added with endometrial sampling in women with Lynch syndrome (LS). The aim of this study was to evaluate the additional value of endometrial sampling in detecting (pre)malignancies of the endometrial tissue in women with LS or first-degree relatives. METHODS: All women above 30 years of age with LS or first-degree relatives at 50% risk of LS are offered annual gynecological screening in our family cancer clinic. Endometrial screening results from January 2003-December 2007 (period I: standard screening by transvaginal sonography and serum CA125) were compared with screening results from January 2008-June 2012 (period II: standard screening added with endometrial sampling). RESULTS: Seventy five women (300 patient years) were screened annually. There were 266 screening visits, 117 in period I and 149 in period II. In period I, four premalignant endometrial lesions were detected and one endometrial carcinoma (FIGO stage IB). In period II, two premalignancies were found. None of the lesions would have been missed without standard endometrial sampling. No interval endometrial cancers were detected in this study. CONCLUSION: In this study, annual endometrial screening seems an effective screening tool in the detection of premalignancies and early endometrial cancer in women with LS. Adding standard endometrial sampling to annual TVU has no additional value in the early detection of (pre)malignant endometrial lesions in women with LS in this study.
