Background: Evidence on the optimal follow-up schedule after endometrial cancer is lacking. The study aim was to compare satisfaction with care between women who received reduced follow-up care and women who received usual guideline-directed follow-up care for three years after surgery.

Methods: The ENSURE (ENdometrial cancer SURvivors' follow-up carE) trial was a non-inferiority randomized controlled multicenter trial in 42 hospitals in the Netherlands.

Objective: To assess the association between loss of lumbar skeletal muscle mass and density during neoadjuvant chemotherapy (NACT) and postoperative complications after interval cytoreductive surgery (CRS) in older patients with ovarian cancer.

Materials And Methods: This multicenter, retrospective cohort study included patients aged 70 years and older with primary advanced stage ovarian cancer (International Federation of Gynecology and Obstetrics stage III-IV), treated with NACT and interval CRS. Skeletal muscle mass and density were retrospectively assessed using Skeletal Muscle Index (SMI) and Muscle Attenuation (MA) on routinely made Computed Tomography scans before and after NACT.

Objective: To determine the predictive value of lumbar skeletal muscle mass and density for postoperative outcomes in older women with advanced stage ovarian cancer.

Methods: A multicenter, retrospective cohort study was performed in women ≥ 70 years old receiving surgery for primary, advanced stage ovarian cancer. Skeletal muscle mass and density were assessed in axial CT slices on level L3.

BRCA1/2 variant analysis in tumor tissue could streamline the referral of patients with epithelial ovarian, fallopian tube, or primary peritoneal cancer to genetic counselors and select patients who benefit most from targeted treatment. We investigated the sensitivity of BRCA1/2 variant analysis in formalin-fixed, paraffin-embedded tumor tissue using a combination of next-generation sequencing and copy number variant multiplex ligation-dependent probe amplification. After optimization using a training cohort of known BRCA1/2 mutation carriers, validation was performed in a prospective cohort in which screening of BRCA1/2 tumor DNA and leukocyte germline DNA was performed in parallel.

Objective: To study diagnostic and therapeutic strategies, outcomes, and follow-up in a large series of women with adenocarcinoma in situ (AIS) of the uterine cervix and investigate if human papillomavirus (HPV) typing among women with negative cytology reports would have helped with early AIS detection.

Materials And Methods: Records of 132 AIS cases diagnosed between 1989 and 2012 were retrieved. Clinical and pathological data were reviewed and analyzed.

Objective: This study aimed to review literature if therapeutic strategies in adenocarcinoma in situ of the cervix could lead to a more conservative approach.

Methods: A review of the literature was conducted using a Medline search for articles published between 1966 and 2013.

Results: Thirty-five studies showed that after a radical cone, 16.

Background: For early squamous cell carcinoma of the uterine cervix, the outcome is similar after either primary surgery or primary radiotherapy. There are reports that this is not the case for early adenocarcinoma (AC) of the uterine cervix: some studies have reported that the outcome is better after primary surgery. There are no systematic reviews about surgery versus chemoradiation in the treatment of cervical cancer.

Objective: To review and characterise by clinical evaluation, immunohistochemistry and HPV typing a group of adenocarcinomas initially diagnosed with primary localisation in the cervix. Furthermore, to assess the prevalence and prognostic significance of HPV genotypes in a large series of HPV positive cervical adenocarcinomas (AC).

Methods: One hundred and seventy-one cases of adenocarcinomas (AC) with a primary localisation in the cervix and diagnosed between 1989 and 2008 in the region of Rotterdam, the Netherlands were retrieved.

Objective: This study aimed to evaluate the treatment and follow-up in a large series of women with early cervical adenocarcinoma (AC), stages IA1 and IA2, and to perform an extensive review of the literature in an effort to ascertain whether conservative therapy is justified.

Methods: Records of 59 cases of microinvasive AC diagnosed between 1987 and 2006 in the Rotterdam district, the Netherlands, were retrieved. Clinical and pathological data were reviewed and analyzed.

Objective: Over 90% of all cervical adenocarcinoma are caused by a transforming infection with a high-risk type human papillomavirus (hrHPV). Previous studies demonstrated that the association between hrHPV positivity and cervical clear-cell adenocarcinoma (CCAC) varies between 0% and 100%. As approximately 60% of all CCAC are associated with intra-uterine diethylstilbestrol (DES) exposure, we determined in a cohort of both DES-exposed and DES-unexposed women the prevalence of hrHPV infections, and the potential etiological role of hrHPV by additional analysis of p16INK4a and p53 expression.

We investigated the significance of prognostic markers-estrogen receptor, progesterone receptor, p53, MIB-1 and bcl-2 - in adenocarcinoma of the uterine cervix. In 101 patients with primary cervical adenocarcinoma, treated from 1989 to 2000, we evaluated clinical parameters in relation to these prognostic markers. Mean age of patients was 45 years.

Purpose: To analyze the use of genetic testing, prophylactic mastectomy, and oophorectomy among women with breast and/or ovarian cancer from families with a BRCA1 or BRCA2 mutation.

Patients And Methods: We examined prospectively the use of BRCA1/BRCA2 testing in all women with a primary breast or ovarian cancer from a consecutive series of 112 high-risk families in which a BRCA1/BRCA2 mutation eventually was identified. The rate of prophylactic bilateral and contralateral mastectomy and prophylactic oophorectomy was analyzed in the women who carried a BRCA1/BRCA2 mutation and who had no metastatic disease at the time of the genetic test disclosure.
