Background: The value of hospital registries for describing treatment and survival outcomes for vulval cancer was investigated. Hospital registry data from four major public hospitals in 1984-2016 were used because population-based data lacked required treatment and outcomes data. Unlike population registries, the hospital registries had recorded FIGO stage, grade and treatment.

Article Synopsis
  • Recent findings suggest that the decline in CA-125 levels is not a reliable indicator of treatment response in patients with recurrent ovarian cancer, prompting the use of mathematical modeling to analyze CA-125 dynamics.
  • Data from the CALYPSO trial were examined using a semi-mechanistic model to understand factors influencing CA-125 levels during treatment and their correlation with progression-free survival (PFS).
  • The study identified key kinetic parameters associated with PFS, confirming the unpredictable nature of traditional CA-125 response and highlighting the elimination rate (KELIM) as a potentially valuable predictive marker for patient outcomes.

Background: Vulvar cancer is a relatively rare malignancy, which occurs most often in postmenopausal women. We have previously identified a geographic cluster of vulvar cancer in young Indigenous women living in remote communities in the Arnhem Land region of Australia. In this population, we investigated the prevalence of oncogenic human papillomavirus (HPV) infection in anogenital samples (vulvar/vaginal/perianal area and cervix) and compared the overall, type-specific and multiple infection prevalence between sites.

Purpose: To estimate the efficacy and toxicity of AMG 386, an investigational peptide-Fc fusion protein that neutralizes the interaction between the Tie2 receptor and angiopoietin-1/2, plus weekly paclitaxel in patients with recurrent ovarian cancer.

Patients And Methods: Patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer were randomly assigned 1:1:1 to receive paclitaxel (80 mg/m(2) once weekly [QW], 3 weeks on/1 week off) plus intravenous AMG 386 10 mg/kg QW (arm A), AMG 386 3 mg/kg QW (arm B), or placebo QW (arm C). The primary end point was progression-free survival (PFS).

Synchronous malignancies are rare diagnostic and treatment challenges. Here we present three cases of synchronous ovarian cancer and lymphoma. Both malignancies were recognised in the same histopathology sections.

Background: The ovarian follicular basal lamina underlies the epithelial membrana granulosa and maintains the avascular intra-follicular compartment. Additional layers of basal lamina occur in a number of pathologies, including pili annulati and diabetes. We previously found additional layers of follicular basal lamina in a significant percentage of healthy bovine follicles.

Objective: To describe the epidemiological features of a possible disease cluster of vulvar cancer and pre-cancers in Australian Indigenous women living in the Northern Territory (NT) of Australia.

Methods: We identified NT-resident women with a confirmed histological diagnosis of vulvar cancer or high-grade vulvar intraepithelial neoplasia (VIN) between 1 January 1996 and 31 December 2005.

Results: Seventy-one women were identified; 32 diagnosed with vulvar cancer and 39 with high-grade VIN.

Background: Epithelial ovarian cancer presents most often as late stage disease due to a lack of effective screening tests and vagueness of symptoms.

Objective: This article outlines the diagnosis and management of ovarian cancer.

Discussion: Women with suspected ovarian cancer are best managed in a gynaecological treatment unit offering multidisciplinary care.

Background: No consensus exists which patients with surgical stage 1 epithelial ovarian should receive postoperative chemotherapy. The purpose of this study was to evaluate the prognostic impact of preoperative CA-125 and to establish a prognostic index to identify patients in different risk categories.

Methods: Data of 600 surgically staged patients with FIGO stage 1 EOC treated in eleven gynecological cancer centers in Australia, the USA and Europe were analyzed.

Objective: To analyze patterns and frequency of recurrences of squamous cell carcinoma (SCC) of the vulva after wide local excision (WLE) and superficial inguinal lymphadenectomy with separate incisions and to identify prognostic factors for the development of recurrences.

Methods: Between January 1985 and December 1999, all 125 consecutive patients with primary SCC of the vulva, treated with WLE and superficial inguinal lymphadenectomy, were retrospectively analyzed. Recurrences were registered by localization as: local, skin bridge, groin or distant.

Purpose: To evaluate the prognostic significance of preoperative CA-125 levels on overall survival of patients with International Federation of Gynecology and Obstetrics (FIGO) stage I epithelial ovarian cancer (EOC).

Patients And Methods: Data from 518 patients with FIGO stage I EOC treated in seven gynecologic oncology centers throughout Australia between 1990 and 2002 were analyzed. Patients with borderline tumors and nonepithelial ovarian carcinomas were excluded, as were women in whom CA-125 had not been determined preoperatively.

Objective: To assess the incidence of Pap smear abnormalities and cervical intraepithelial neoplasia (CIN) on cervical biopsy results in teenage mothers and to establish if there are associations with social disruption.

Patients And Methods: A prospective study of 498 pregnant teenagers was performed at three Australian hospitals. Enrolled patients had a Pap smear performed.

Objective: To investigate survivals from cervical cancer, with special reference to effects of glandular histology and its influence on prognostic characteristics and management decisions.

Methods: Data on cervical cancers, diagnosed in 1984-2000, were obtained from the gynecologic oncology registry of hospitals of the University of Adelaide. Comparisons were made of disease-specific survival, age at diagnosis, diagnostic period, stage, grade, and primary course of treatment.
