The MEMORY Study: MulticentEr study of Minimally invasive surgery versus Open Radical hYsterectomy in the management of early-stage cervical cancer: Survival outcomes.

OBJECTIVE: The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy. METHODS: This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016. Patients who underwent preoperative therapy were excluded. Squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinomas were included. Appropriate statistical tests were used. RESULTS: We identified 1093 cases for analysis-715 MIS (558 robotic [78%]) and 378. OPEN procedures. The OPEN cohort had more patients with tumors >2 cm, residual disease in the hysterectomy specimen, and more likely to have had adjuvant therapy. Median follow-up for the MIS and OPEN cohorts were 38.5 months (range, 0.03-149.51) and 54.98 months (range, 0.03-145.20), respectively. Three-year PFS rates were 87.9% (95% CI: 84.9-90.4%) and 89% (95% CI: 84.9-92%), respectively (P = 0.6). On multivariate analysis, the adjusted HR for recurrence/death was 0.70 (95% CI: 0.47-1.03; P = 0.07). Three-year OS rates were 95.8% (95% CI: 93.6-97.2%) and 96.6% (95% CI: 93.8-98.2%), respectively (P = 0.8). On multivariate analysis, the adjusted HR for death was 0.81 (95% CI: 0.43-1.52; P = 0.5). CONCLUSION: This multi-institutional analysis showed that an MIS compared to OPEN radical hysterectomy for cervical cancer did not appear to compromise oncologic outcomes, with similar PFS and OS.

Improving the quality of care for patients with advanced epithelial ovarian cancer: Program components, implementation barriers, and recommendations.

The high lethality of ovarian cancer in the United States and associated complexities of the patient journey across the cancer care continuum warrant an assessment of current practices and barriers to quality care in the United States. The objectives of this study were to identify and assess key components in the provision of high-quality care delivery for patients with ovarian cancer, identify challenges in the implementation of best practices, and develop corresponding quality-related recommendations to guide multidisciplinary ovarian cancer programs and practices. This multiphase ovarian cancer quality-care initiative was guided by a multidisciplinary expert steering committee, including gynecologic oncologists, pathologists, a genetic counselor, a nurse navigator, social workers, and cancer center administrators. Key partnerships were also established. A collaborative approach was adopted to develop comprehensive recommendations by identifying ideal quality-of-care program components in advanced epithelial ovarian cancer management. The core program components included: care coordination and patient education, prevention and screening, diagnosis and initial management, treatment planning, disease surveillance, equity in care, and quality of life. Quality-directed recommendations were developed across 7 core program components, with a focus on ensuring high-quality ovarian cancer care delivery for patients through improved patient education and engagement by addressing unmet medical and supportive care needs. Implementation challenges were described, and key recommendations to overcome barriers were provided. The recommendations emerging from this initiative can serve as a comprehensive resource guide for multidisciplinary cancer practices, providers, and other stakeholders working to provide quality-directed cancer care for patients diagnosed with ovarian cancer and their families.

A pilot study of topical imiquimod therapy for the treatment of recurrent extramammary Paget's disease.

OBJECTIVE: The objective of this prospective pilot study was to assess the clinical and histologic effects of topical imiquimod therapy on recurrent extramammary Paget's disease of the vulva. METHODS: Patients with biopsy-proven recurrent extramammary Paget's disease presenting to the gynecology outpatient services at two participating institutions were recruited for conservative treatment with 5% imiquimod cream from 2007 to 2011. The topical cream was to be applied 3 times per week for 12weeks. Punch biopsy and photography were performed at baseline and at the 12-week time point. RESULTS: Eight patients from two institutions were enrolled. Complete clinical and histologic response was achieved in 6 (75%) patients by the 12-week follow-up appointment. Of the two remaining patients, one had a complete clinical response but no significant histologic response; the other patient was removed from the study protocol secondary to intolerable local irritation. Two patients continue to have no evidence of disease after a median follow-up of 35months. Five are alive with disease. No patients progressed to invasive cancer while receiving therapy. CONCLUSION: Topical 5% imiquimod cream is a safe and feasible option for women suffering from recurrent extramammary Paget's disease of the vulva, and should be considered as a viable alternative to surgical management. Given the rare nature of this disease, additional multi-institutional prospective studies should be conducted to explore the efficacy of this treatment regime.

Neuroendocrine tumors in the ovary: histogenesis, pathologic differentiation, and clinical presentation.

OBJECTIVE: Primary neuroendocrine tumors in the ovary are rare. These tumors arise from the neuroendocrine cell system of ovarian stroma and surface epithelium, and may also arise from teratoma. We present four primary ovarian neuroendocrine tumors and compare clinicopathologic findings based on tumor histogenesis and site of origin. DESIGN: Four primary ovarian neuroendocrine tumors were identified from our 10-year departmental archives. H&E slides and immunostains were reviewed and the diagnoses were confirmed. Clinical history, imaging studies, and follow-up data were obtained from medical records. RESULTS: Patients' ages ranged from 26 to 63. All patients presented with abdominal discomfort and unilateral or bilateral ovarian masses. MRI and CT scans from cases 1 and 2 revealed a solid ovarian mass with no extra-ovarian extension. In case 1, the patient also had a cystic mass in the opposite ovary and an elevated urine 5-HIAA. Microscopically, case 1 revealed a well-differentiated carcinoid tumor with no surface epithelial involvement, and a mature teratoma in the contralateral ovary. Case 2 revealed a stromal carcinoid within the ovarian parenchyma. Imaging studies from cases 3 and 4 showed large complex masses with peritoneal implants and ascites. In both cases 3 and 4, tumor grossly involved both ovarian parenchyma and surface epithelium with multiple pelvic implants. In addition, liver metastases were present in case 4. Microscopically, these tumors were poorly differentiated carcinoma with neuroendocrine differentiation. Histologic sections revealed extensive necrosis, and both cases showed positivity for neuroendocrine markers. CONCLUSIONS: Primary neuroendocrine tumors in the ovary are rare and consist of a group of heterogeneous malignancies that express similar immunohistochemical markers. Primary neuroendocrine tumors that are limited to the ovarian parenchyma often arise from ovarian stroma and teratoma, and are carcinoid tumors with a good prognosis. Neuroendocrine tumors that arise from surface epithelium or dedifferentiate from de novo carcinoma often involve both ovarian stroma and surface epithelium and clinically present as aggressive malignancies with poor prognoses.

Management of Persistent Postpartum Hemorrhage Caused by Inner Myometrial Lacerations.

BACKGROUND: Postpartum hemorrhage management must involve rapid recognition of the source of bleeding. Inner myometrial laceration is an uncommonly recognized cause; most cases are demonstrated only by evaluation of peripartum hysterectomy specimens. The exact cause of this laceration is unknown; however, it can be identified by uterine cavity exploration and managed with conservative surgery that preserves fertility. CASE: Postpartum hemorrhage caused by inner myometrial lacerations is presented. We explored the uterine cavity through laparotomy and uterine hysterotomy to identify and repair the source of bleeding. CONCLUSION: In persistent hemorrhage that fails initial interventions, inner myometrial laceration should be considered. Uterine cavity exploration with laparotomy incision and hysterotomy to directly visualize the source are essential steps to manage postpartum hemorrhage while avoiding maternal morbidity, peripartum hysterectomy, and potential mortality.

Patterns of first recurrence following adjuvant intraperitoneal chemotherapy for stage IIIC ovarian cancer.

OBJECTIVE: Adjuvant intraperitoneal (IP) platinum-based chemotherapy has been shown to improve outcome for patients with advanced ovarian cancer. We hypothesize that patients who have received adjuvant IP chemotherapy more commonly recur first at extraperitoneal sites than patients who have received adjuvant intravenous (IV) chemotherapy. METHODS: Patients with newly diagnosed stage IIIC optimally debulked serous ovarian cancer were identified from institutional databases. Patterns of recurrence were compared between patients who received IV and IP chemotherapy using standard two-sided statistical tests. RESULTS: Of the 104 patients who met inclusion criteria, 60 received IV chemotherapy and 44 received IP chemotherapy. Patients in the IV group had a first recurrence more commonly in the lower abdomen or pelvis than the IP group. Patients in the IP group more commonly recurred in the upper abdomen and extra-abdominal lymph nodes. More patients in the IP group than the IV group recurred at extra-abdominal sites (45.5% versus 23.3%, P=0.018). CONCLUSIONS: Patients receiving adjuvant IP chemotherapy are less likely to first recur in the lower abdomen or pelvis and more likely to recur outside of the abdominal cavity. The data suggest that IP chemotherapy is highly effective in the anatomic areas of peritoneal distribution.
