Prognostic value and clinicopathologic characteristics of L1 cell adhesion molecule (L1CAM) in a large series of vulvar squamous cell carcinomas.

Background: Vulvar cancer treatment is mostly curative, but also has high morbidity rates. In a search for markers that can identify patients at risk of metastases, we investigated the prognostic value of L1-cell adhesion molecule (L1CAM) in large series of vulvar squamous cell carcinomas (VSCCs). L1CAM promotes cell motility and is an emerging prognostic factor for metastasis in many cancer subtypes.

An evaluation of the current state of sexual and reproductive health and rights of women in Ghana.

Objective: To provide a current account of women's sexual and reproductive health and rights (SRHR) in Ghana (West Africa), a priority area in achieving the World Health Organization's Millennium Development Goals.

Method: The study was observational. Three-hundred ninety Ghanaian women attending cervical cancer screening were surveyed about their SRHR.

Precise Classification of Cervical Carcinomas Combined with Somatic Mutation Profiling Contributes to Predicting Disease Outcome.

Introduction: Squamous cell carcinoma (SCC), adenocarcinoma (AC), and adenosquamous carcinoma (ASC) are the most common histological subtypes of cervical cancer. Differences in the somatic mutation profiles of these subtypes have been suggested. We investigated the prevalence of somatic hot-spot mutations in three well-defined cohorts of SCC, AC, and ASC and determined the additional value of mutation profiling in predicting disease outcome relative to well-established prognostic parameters.

The Value of Intraoperative Near-Infrared Fluorescence Imaging Based on Enhanced Permeability and Retention of Indocyanine Green: Feasibility and False-Positives in Ovarian Cancer.

Objective: In ovarian cancer, two of the most important prognostic factors for survival are completeness of staging and completeness of cytoreductive surgery. Therefore, intra-operative visualization of tumor lesions is of great importance. Preclinical data already demonstrated tumor visualization in a mouse-model using near-infrared (NIR) fluorescence imaging and indocyanine green (ICG) as a result of enhanced permeability and retention (EPR).

Differences in genetic variation in antigen-processing machinery components and association with cervical carcinoma risk in two Indonesian populations.

Genetic variation of antigen-processing machinery (APM) components has been shown to be associated with cervical carcinoma risk and outcome in a genetically homogeneous Dutch population. However, the role of APM component single nucleotide polymorphisms (SNPs) in genetically heterogeneous populations with different distributions of human papillomavirus (HPV) subtypes remains unclear. Eleven non-synonymous, coding SNPs in the TAP1, TAP2, LMP2, LMP7 and ERAP1 genes were genotyped in cervical carcinoma patients and healthy controls from two distinct Indonesian populations (Balinese and Javanese).

Sentinel Lymph Node Biopsy in Vulvar Cancer Using Combined Radioactive and Fluorescence Guidance.

Objective: Near-infrared (NIR) fluorescence imaging using indocyanine green (ICG) has recently been introduced to improve the sentinel lymph node (SLN) procedure. Several optical tracers have been successfully tested. However, the optimal tracer formulation is still unknown.

CDKN2A(p16) and HRAS are frequently mutated in vulvar squamous cell carcinoma.

Background: Two etiologic pathways of vulvar cancer are known, a human papillomavirus (HPV)- and a TP53-associated route, respectively, but other genetic changes may also play a role. Studies on somatic mutations in vulvar cancer other than TP53 are limited in number and size. In this study, we investigated the prevalence of genetic mutations in 107 vulvar squamous cell carcinomas (VSCCs).

Nerve-sparing radical abdominal trachelectomy versus nerve-sparing radical hysterectomy in early-stage (FIGO IA2-IB) cervical cancer: a comparative study on feasibility and outcome.

Objectives: Standard treatment in early-stage cervical cancer is a radical hysterectomy (RH) with pelvic lymphadenectomy. In women who wish to preserve fertility radical vaginal trachelectomy has been proposed; however, this is not feasible in larger tumors, and nerve-sparing surgery is not possible. Nerve-sparing radical abdominal trachelectomy (NSRAT) overcomes these disadvantages.

Oncologists' practice and attitudes regarding fertility preservation in female cancer patients: a pilot study in the Netherlands.

Purpose: The aim of this study was to assess oncologists' practice and attitudes regarding treatment-related infertility and fertility preservation in female cancer patients of reproductive age.

Participants And Methods: Recruitment letters with a 7-item questionnaire were sent to 454 oncologists.

HLA-E expression in cervical adenocarcinomas: association with improved long-term survival.

Background: Cervical cancer is the third most common cancer in women worldwide. The most common histopathological subtype is cervical squamous cell carcinoma (SCC, 75-80%), followed by adenocarcinoma (AC) and adenosquamous carcinoma (ASC; together 15-20%). Rising incidence rates of AC have been observed relative and absolute to SCC and evidence is accumulating that cervical AC is a distinct clinical entity.

Cervical cancer prevention program in Jakarta, Indonesia: See and Treat model in developing country.

Objective: The purpose of this study was to describe the implementation of single visit approach or See-visual inspection of the cervix with acetic acid (VIA)-and Treat-immediate cryotherapy in the VIA positive cases-model for the cervical cancer prevention in Jakarta, Indonesia.

Methods: An observational study in community setting for See and Treat program was conducted in Jakarta from 2007 until 2010. The program used a proactive and coordinative with VIA and cryotherapy (Proactive-VO) model with comprehensive approach that consists of five pillars 1) area preparation, 2) training, 3) awareness, 4) VIA and cryotherapy, and 5) referral.

Randomized comparison of near-infrared fluorescence lymphatic tracers for sentinel lymph node mapping of cervical cancer.

Objective: Near-infrared fluorescence imaging using indocyanine green (ICG) has recently been introduced as a novel technique for sentinel lymph node (SLN) mapping in early-stage cervical cancer. Although preclinical research has shown that ICG adsorbed to human serum albumin (ICG:HSA) improves its performance, the need for HSA has not yet been confirmed in cervical cancer patients. The current randomized study aims to determine whether ICG:HSA offers advantages over using ICG alone.

[Actinomycosis resembling an ovarian malignancy].

Background: Actinomyces is an uncommon cause of infection which can occur in the lower pelvic area in women using an intrauterine device (IUD). The clinical presentation of actinomycosis can easily be confounded with a malignancy.

Case Description: In a 53-year-old woman with abdominal pain and fluctuating temperature, ovarian carcinoma was strongly suspected.

Timing of fertility preservation procedures in a cohort of female patients with cancer.

Objective: Comparison of time intervals from diagnosis to chemotherapy between patients opting for embryo cryopreservation or ovarian tissue cryopreservation.

Study Design: Retrospective analysis.

Setting: University hospital in the Netherlands.

Optimization of near-infrared fluorescent sentinel lymph node mapping in cervical cancer patients.

Objective: In early cervical cancer, a total pelvic lymphadenectomy is the standard of care, even though most patients have negative nodes and thus undergo lymphadenectomy unnecessarily. Although the value of sentinel lymph node (SLN) mapping in early-stage cervical cancer has not yet been established, near-infrared (NIR) fluorescence imaging is a promising technique to perform this procedure. Near-infrared fluorescence imaging is based on invisible NIR light and can provide high sensitivity, high-resolution, and real-time image guidance during surgery.

Optimization of near-infrared fluorescent sentinel lymph node mapping for vulvar cancer.

Objectives: Near-infrared fluorescence imaging has the potential to improve sentinel lymph node mapping in vulvar cancer, which was assessed in the current study. Furthermore, dose optimization of indocyanine green adsorbed to human serum albumin was performed.

Study Design: Nine vulvar cancer patients underwent the standard sentinel lymph node procedure using (99m)technetium-nancolloid and patent blue.

Nerve sparing in radical surgery for early-stage cervical cancer: yes we should!

Radical hysterectomy with pelvic lymphadenectomy is considered to be the cornerstone in the treatment of early-stage cervical cancer. Although survival in early-stage cervical cancer is up to 95%, long-term morbidity with regard to bladder, bowel, and sexual function is considerable. Damage to the pelvic autonomic nerves may be the cause of these long-term complications following radical hysterectomy.

Abdominal scar recurrences of cervical cancer: incidence and characteristics: a case-control study.

Background: Tumor recurrence in the surgical scar after radical hysterectomy for cervical cancer has been reported, but the incidence is unknown. Facts about patient and tumor characteristics and follow-up are lacking. The objective of this study was to analyze the incidence and characteristics of cervical cancer scar recurrences.

Nerve-sparing radical hysterectomy: local recurrence rate, feasibility, and safety in cervical cancer patients stage IA to IIA.

Unlabelled: To clarify the debate about the possible threat of sparing the pelvic autonomic nerves in radical hysterectomy for cervical cancer to radicality, comparative studies of nerve-sparing and conventional surgery are necessary. The aim of his study was to analyze and compare local recurrence rate, feasibility, and safety of nerve-sparing and non-nerve-sparing radical hysterectomy.

Methods: In a cohort study with 2 years of follow-up, 246 patients with cervical cancer of stages IA to IIA were analyzed: 124 in the non-nerve-sparing group (1994-1999) and 122 in the group where nerve-sparing was the intention-to-treat (2001-2005).

Female fertility preservation: practical and ethical considerations of an underused procedure.

Purpose: Cancer treatments for young women can permanently or temporarily affect fertility. The purpose of this retrospective analysis was to present the clinical experience and ethical considerations of fertility preservation in female oncology patients in a tertiary gynaecological department.

Methods: Since 2002, in 37 patients fertility preservation was performed according to an institutional review board approved protocol in a University hospital in the Netherlands; 33 patients were not treated.

Physical status of multiple human papillomavirus genotypes in flow-sorted cervical cancer cells.

Multiple human papilloma virus (HPV) infections have been detected in cervical cancer. To investigate the significance of multiple HPV infections, we studied their prevalence in cancer samples from a low-risk (Dutch) and a high-risk (Surinamese) population and the correlation of HPV infection with tumor cell aneuploidy. SPF(10) LiPA was used for HPV detection in formalin-fixed cervical carcinoma samples from 96 Dutch and 95 Surinamese patients.

Expression and genetic analysis of transporter associated with antigen processing in cervical carcinoma.

Objective: Transporter associated with antigen processing (TAP) loss causes human leukocyte antigen (HLA) class I downregulation which is frequently found in cervical carcinomas and their precursors. HLA class I molecules activate T-cells by antigen presentation and are therefore essential for immunological surveillance. To add to the hitherto limited knowledge of molecular mechanisms underlying TAP loss, we investigated TAP expression, loss of heterozygosity (LOH) and possible TAP mutations.

High human papillomavirus oncogene mRNA expression and not viral DNA load is associated with poor prognosis in cervical cancer patients.

Purpose: Cervical cancer is now known to be caused by infection with an oncogenic type of the human papillomavirus (HPV). However, little is known about the continued role of HPV once cancer has been established. Here, we describe the quantitative relation between HPV DNA copy number and mRNA expression of the viral oncogenes (E6 and E7) and the prognostic value of both measures in cervical cancer patients.

Reasons for early interventions by gynaecologists in a clinical follow-up study on cervical intraepithelial neoplasia.

Objective: In a previous clinical follow-up study on psychosocial factors and cervical intraepithelial neoplasia (CIN), we had noticed a high percentage of early interventions to the cervix by gynaecologists, in discordance with the research protocol. The aim of the current study was to investigate the reasons for these interventions.

Study Design: We retrospectively analysed the study records of the clinical study, concerning the follow-up of 98 patients with a CIN 1 or 2 lesion for 2.

Frequent HLA class I loss is an early event in cervical carcinogenesis.

Loss at chromosome 6p21.3, the human leukocyte antigen (HLA) region, is the main cause of HLA downregulation, occurring in the majority of invasive cervical carcinomas. To identify the stage of tumor development at which HLA class I aberrations occur, we selected 12 patients with cervical carcinoma and adjacent cervical intraepithelial neoplasia (CIN).
