Cancer in pregnancy is rare, and most physicians lack knowledge in handling pregnant cancer patients. This review summarises the present knowledge on this condition. In the Netherlands, an Advisory Board on Cancer in Pregnancy was established in 2012.

Hereditary Polyposis Syndromes are a group of rare, inherited syndromes characterized by the presence of histopathologically specific or numerous intestinal polyps and an increased risk of cancer. Some polyposis syndromes have been known for decades, but the development in genetic technologies has allowed the identification of new syndromes..

Hereditary polyposis syndromes (HPS) are a group of rare, inherited syndromes characterised by the presence of histopathological specific or numerous intestinal polyps and a high risk of intestinal and extraintestinal cancer. During the last decade, several new HPS have been discovered, as it is possible to detect pathogenic germline variants in genes not previously known to be associated with polyposis. This review summarises the current knowledge on the syndromes and discusses genetic testing as part of the diagnostic pipeline when suspecting a polyposis syndrome.

Purpose: This study aimed to report the uptake of hysterectomy and/or bilateral salpingo-oophorectomy (BSO) to prevent gynaecological cancers (risk-reducing surgery [RRS]) in carriers of pathogenic MMR (path_MMR) variants.

Methods: The Prospective Lynch Syndrome Database (PLSD) was used to investigate RRS by a cross-sectional study in 2292 female path_MMR carriers aged 30-69 years.

Results: Overall, 144, 79, and 517 carriers underwent risk-reducing hysterectomy, BSO, or both combined, respectively.

Purpose: To determine impact of risk-reducing hysterectomy and bilateral salpingo-oophorectomy (BSO) on gynecological cancer incidence and death in heterozygotes of pathogenic MMR (path_MMR) variants.

Methods: The Prospective Lynch Syndrome Database was used to investigate the effects of gynecological risk-reducing surgery (RRS) at different ages.

Results: Risk-reducing hysterectomy at 25 years of age prevents endometrial cancer before 50 years in 15%, 18%, 13%, and 0% of path_MLH1, path_MSH2, path_MSH6, and path_PMS2 heterozygotes and death in 2%, 2%, 1%, and 0%, respectively.

Article Synopsis
  • Lynch syndrome is caused by certain gene changes (MLH1, MSH2, MSH6, PMS2) that can lead to different kinds of cancer risks depending on the gene and gender.
  • A study looked at 6,350 people with these gene changes to find out more about their specific cancer risks and survival rates.
  • They found that MLH1 and MSH2 carriers had higher cancer risks, especially for colorectal and endometrial cancers, while MSH6 mainly increased endometrial cancer risk, and not much for PMS2. Most people lived over 10 years after getting treated for these cancers.

Ovarian cancer linked to Lynch syndrome represents a rare subset that typically presents at young age as early-stage tumors with an overrepresentation of endometrioid and clear cell histologies. We investigated the molecular profiles of Lynch syndrome-associated and sporadic ovarian cancer with the aim to identify key discriminators and central tumorigenic mechanisms in hereditary ovarian cancer. Global gene expression profiling using whole-genome c-DNA-mediated Annealing, Selection, extension, and Ligation was applied to 48 histopathologically matched Lynch syndrome-associated and sporadic ovarian cancers.

Objective: We aimed to estimate the incidence rate of endometrial cancer (EC) and to evaluate the results of EC-surveillance in hereditary nonpolyposis colorectal cancer (HNPCC) families.

Methods: All at-risk women recommended for EC-surveillance by the HNPCC-register-2959 women (19,334women years)-were included. Data on EC-surveillance were available for 871 women (6894women years), who had performed 1945 surveillance visits.

Objective: Women with hereditary nonpolyposis colorectal cancer (HNPCC) have a 40-60% lifetime risk for endometrial cancer. Guidelines in Denmark recommend gynecologic screening for female members of families with HNPCC. We estimated the knowledge of endometrial cancer risk and identified possible predictors of compliance with the screening among women from families with HNPCC.

Objective: Heredity is a major cause of ovarian cancer and during recent years the contribution from germline mismatch repair (MMR) gene mutations linked to Lynch syndrome has gradually been recognized.

Methods: We characterized clinical features, tumor morphology and mismatch repair defects in all ovarian cancers identified in Swedish and Danish Lynch syndrome families.

Results: In total, 63 epithelial ovarian cancers developed at mean 48 (range 30-79) years of age with 47% being early stage (FIGO stage I).

Persistent infection with high-risk human papillomavirus (HPV) and expression of the proteins E6 and E7 is a prerequisite for development of cervical cancer. The distal non-coding part of E6/E7 messengers from several HPV types is able to downregulate synthesis of a reporter gene through mechanisms with involvement of cytoplasmic polyadenylation elements (CPEs) in the messengers. We here show that the mRNA levels of one of the four known CPE-binding proteins (CPEBs), the CPEB3, were downregulated in HPV-positive cervical cancers, whereas in ovarian cancer the CPEB1 mRNA level was downregulated.

Introduction: Urinary incontinence (UI) represents a frequent symptom among women of all ages. However, very few women are admitted to a hospital or clinic because of UI. The aim of the paper was to characterize women admitted to hospital because of UI in respect to symptoms and self reported quality of life.
