The role of surgery in gestational trophoblastic disease: an overview.

Gestational trophoblastic disease comprises a group of rare, and potentially malignant, conditions that arise from abnormal trophoblastic proliferation. When there is invasion and evidence of metastatic disease, gestational trophoblastic neoplasia is used. While chemotherapy is the mainstay of treatment for gestational trophoblastic neoplasia, the role of surgery has come full circle in recent years. Before the introduction of highly effective systemic treatment options, surgery was the default treatment. Surgery for gestational trophoblastic neoplasia often yielded unsatisfactory results and mortality remained high. In recent years, the role of adjuvant surgery in the management of gestational trophoblastic neoplasia has been examined with great interest. We aim to provide an overview of the various surgical approaches employed in managing gestational trophoblastic neoplasia, including their indications, techniques, and outcomes. Additionally, we discuss whether there is a role to do less in surgery for gestational trophoblastic neoplasia and describe our experience with a modified surgical technique for its treatment. By summarizing the current evidence, this article highlights the significant contributions of surgery to the holistic management of patients with gestational trophoblastic neoplasia and provides a framework on which to base management and treatment programs.

Cervical screening in foreign domestic workers in Singapore.

INTRODUCTION: Globally, cervical cancer is the fourth most common cancer in women, with about 85% occurring in low-middle income countries (LMIC) and an age-standardised incidence rate of more than 15 per 100,000. It is largely preventable through HPV vaccination and cervical cancer screening. In Singapore, 18% of the foreign domestic workforce hail from Indonesia, the Philippines, Myanmar, and India. However, there is no data on preinvasive cervical disease and cervical cancer in foreign domestic workers (FDWs) and the aim of this pilot programme is to determine the baseline screen positive rate of high-grade intraepithelial in this population. METHODS: A total of 322 FDWs were offered HPV screening through the Helping Our Helper (HOH) pilot programme. Data from this pilot programme were analysed and reported using simple descriptive statistics. RESULTS: Out of the 322 FDWs who registered for HPV screening, 68.6% participated. There was a 22.2% screen-positive rate; 10% of those who screened positive for high-risk HPV had histologically confirmed high-grade cervical intraepithelial neoplasia. This result is similar to other data on cervical cancer screening in Singaporeans. This pilot project screened less than 1% of the eligible FDWs in Singapore. DISCUSSION: The findings of this pilot programme suggest that there is public health value in providing cervical cancer screening to FDWs. Improving cervical cancer screening by increasing awareness and including routine cervical cancer screening as part of the employment medical examination should be studied.

Variations in gynecologic oncology training in low (LIC) and middle income (MIC) countries (LMICs): Common efforts and challenges.

Gynecologic cancer, cervical cancer in particular, is disproportionately represented in the developing world where mortality is also high. Screening programs, increased availability of chemotherapy, and an awareness of HIV-related cancers have in part accelerated a need for physicians who can treat these cancers, yet the infrastructure for such training is often lacking. In this paper, we address the variations in gynecology oncology training in LMICs as well as the ubiquitous challenges, in an effort to guide future agendas.

Malignant ovarian germ-cell tumours.

Malignant ovarian germ-cell tumours account for about 5% of all ovarian malignancies and typically present in the teenage years. They are almost always unilateral and are exquisitely chemosensitive. As such, the surgical approach in young women with such tumours confined to a single ovary should aim to preserve fertility. In early disease, a unilateral salpingo-oophorectomy with careful surgical staging is of great importance in selecting appropriate adjuvant therapy. In advanced disease, the role of aggressive cytoreducation is not well defined, and removal of both ovaries does not confer improvement in outcome. Bleomycin, etoposide and cisplatin combination chemotherapy is regarded as the gold standard for adjuvant therapy. Studies evaluating ovarian and reproductive capacity after conservative surgery and chemotherapy for malignant ovarian germ-cell tumours have consistently demonstrated excellent prognosis, with the return of normal menstrual function and fertility rates in these women with no increase in the risk of teratogenicity.

Gynaecological cancer in pregnancy.

Cancer in pregnancy, fortunately, is uncommon. This is even more so for gynaecological cancer. Fertility preservation in gynaecological cancer is already a difficult issue, as the common gynaecological cancers affect organs intimately associated with conception and delivery. The presence of a viable pregnancy with gynaecological cancer presents tremendous challenges to the clinician, especially if the woman wants to conserve both her pregnancy and fertility. In this chapter, we address issues involved in such circumstances and suggest management decisions.

Epithelial ovarian cancer.

The incidence of epithelial ovarian cancer in women aged 40 years and younger is 3-17%. The management of these women is challenging and requires balancing the need to treat epithelial ovarian cancer adequately and preserving reproductive potential. Fertility-sparing surgery, especially for early stage epithelial ovarian cancer, seems to be associated with equivalent clinical and cancer outcomes while preserving reproductive potential. A complete staging and cytoreductive procedure retaining the uterus, and at least one grossly normal ovary, is the minimum recommended procedure. Adjuvant chemotherapy with a platinum-taxane combination is recommended as clinically indicated, and is associated with better cancer and survival outcomes. Adjuvant treatment does not seem to increase the risk of congenital anomalies in subsequent pregnancies. Targeted therapy and ovarian cryopreservation are largely experimental and cannot be recommended as part of the clinical standard of care.

Port-site recurrence in a patient undergoing robot-assisted gynecologic cancer surgery for endometrial cancer - A case report.

► First case of port-site metastasis after robotic staging surgery for uterine cancer. ► Changes to robotic surgical technique to reduce risk of port-site recurrence. ► Further areas of investigation worth examining in this aspect of robotic surgery.

A clinicopathologic study of uterine smooth muscle tumours of uncertain malignant potential (STUMP).

INTRODUCTION: The clinical management of Smooth Muscle Tumours of Uncertain Malignant Potential (STUMPs) remains controversial because little is known about the natural history of these tumours and pathological classifications do not correlate well with clinical outcomes and therefore cannot direct management. The objective of this study was to review a single institution's experience with STUMP and recommend a rational clinical approach to the management of patients with this histological diagnosis. MATERIALS AND METHODS: A systematic review of all diagnoses of STUMP and leiomyosarcoma from the gynaecologic oncology and pathology databases between January 1970 and February 2006. RESULTS: A total of 18 diagnoses of STUMP and 72 diagnoses of Ieiomyosarcoma were made during the study period. None of these 72 cases of leiomyosarcoma had a prior diagnosis of STUMP. There were no recurrences in the 18 cases of STUMP with all 18 cases being registered as disease-free after 5 years. CONCLUSIONS: We recommend that patients with a diagnosis of STUMP be expectantly managed given the low likelihood of leiomyosarcomatous transformation, the lack of any evidence that adjuvant treatments result in better long-term outcomes and that recurrences are amenable to surgical resection with good outcomes.
