IgG4-related disease in the pelvis: A mimicker of gynecologic malignancy.

This report describes a unique case of IgG4-related disease in a 36-year-old woman who presented with a pelvic mass. Although CT and MR imaging initially suggested a malignant process, further work-up including sigmoidoscopy and surgical exploration revealed no evidence of malignancy. The final pathology indicated an inflammatory process, leading to the diagnosis of IgG4-related disease. After receiving appropriate systemic treatment, the patient's symptoms significantly improved. This case underscores the limitations of current imaging studies and emphasizes the importance of considering a wide range of potential diagnoses when dealing with pelvic masses of uncertain etiology.

Detection of Residual Peritoneal Metastases Following Cytoreductive Surgery Using Pegsitacianine, a pH-Sensitive Imaging Agent: Final Results from a Phase II Study.

BACKGROUND: For patients with peritoneal carcinomatosis, extent of disease and completeness of cytoreductive surgery (CRS) are major prognostic factors for long-term survival. Assessment of these factors could be improved using imaging agents. Pegsitacianine is a pH-sensitive polymeric micelle conjugated to the fluorophore indocyanine green. The micelle disassembles in acidic microenvironments, such as tumors, resulting in localized fluorescence unmasking. We assessed the utility of pegsitacianine in detecting residual disease following CRS. PATIENTS AND METHODS: NCT04950166 was a phase II, non-randomized, open-label, multicenter US study. Patients eligible for CRS were administered an intravenous dose of pegsitacianine at 1 mg/kg 24-72 h before surgery. Following CRS, the peritoneal cavity was reexamined under near-infrared (NIR) illumination to evaluate for fluorescent tissue. Fluorescent tissue identified was excised and evaluated by histopathology. The primary outcome was the rate of clinically significant events (CSE), defined as detection of histologically confirmed residual disease excised with pegsitacianine or a revision in the assessment of completeness of CRS. Secondary outcomes included acceptable safety and pegsitacianine performance. RESULTS: A total of 53 patients were screened, 50 enrolled, and 40 were evaluable for CSE across six primary tumor types. Residual disease was detected with pegsitacianine in 20 of 40 (50%) patients. Pegsitacianine showed high sensitivity and was well tolerated with no serious adverse events (SAEs). Transient treatment-related, non-anaphylactic infusion reactions occurred in 28% of patients. CONCLUSIONS: Pegsitacianine was well tolerated and facilitated the recognition of occult residual disease following CRS. The high rate of residual disease detected suggests that the use of pegsitacianine augmented surgeon assessment and performance during CRS.

Preoperative and pre-chemotherapy CA-125 levels in high-risk early-stage ovarian cancer - An NRG/GOG study.

OBJECTIVES: To determine clinical significance of preoperative and pre-chemotherapy CA-125 in high-risk early-stage epithelial ovarian cancer patients. METHODS: All patients with stage IA/IB and grade 3, stage IC, clear cell, or completed resected stage II cancer were enrolled in a phase III trial and treated with chemotherapy. Kaplan-Meier method and Cox proportional hazards model were used for statistical analyses. RESULTS: 427 patients with high-risk early-stage ovarian cancer were enrolled. Of 213 patients with preoperative CA-125 data, 79% had elevated CA-125. Median preoperative CA-125 level was 103 U/mL. Patients with ≤10, 11-15, and > 15 cm tumors had median preoperative CA-125 levels of 62, 131 and 158 U/mL, respectively (p = 0.002). For the 350 patients with data for pre-chemotherapy CA-125 level, 69% had elevated pre-chemotherapy CA-125 above 35 U/mL with median value of 65 U/mL. However, age, race, stage, cell type and grade of disease were not correlated with CA-125 levels before and after surgery. On multivariate analysis, elevated pre-chemotherapy CA-125 independently predicted worse recurrence-free survival (HR = 2.13, 95% CI: 1.23-3.69; p = 0.007) and overall survival (HR = 1.99, 95% CI: 1.10-3.59; p = 0.022) after adjusting for age, stage, cell type and grade of disease. Compared to those with normal CA-125, patients with elevated pre-chemotherapy CA-125 had lower recurrence-free survival (RFS, 87% vs. 75%; p = 0.007) and overall survival (OS, 88% vs. 82%; p = 0.02). However, preoperative CA-125 was not prognostic of RFS (p = 0.699) or OS (p = 0.701). CONCLUSIONS: Preoperative CA-125 was elevated in nearly 80% of high-risk early-stage ovarian cancer patients. Pre-chemotherapy CA-125 was associated with recurrence-free and overall survival; however, preoperative CA-125 was not prognostic.

Transvaginal ureteroneocystostomy.

Ureteral injury is a known complication of gynecologic surgery with potential long-term sequelae. Traditional management of significant ureteral injury recognized at the time of transvaginal pelvic organ prolapse repair is a transabdominal re-implantation procedure using a transabdominal open or laparoscopic approach. We present a case describing a transvaginal approach for ureteroneocystostomy. During a transvaginal pelvic organ prolapse repair, a ureteral transection was noted. A transvaginal ureteroneocystostomy was performed. There was primary healing of the ureteroneocystostomy without sequelae during a 6-month follow-up period.

Take me to your leader: Reporting structures and equity in academic gynecologic oncology.

OBJECTIVE: Gynecologic oncology includes increasing percentages of women. This study characterizes representation of faculty by gender and subspecialty in academic department leadership roles relevant to the specialty. METHODS: The American Association of Medical Colleges accredited schools of medicine were identified. Observational data was obtained through institutional websites in 2019. RESULTS: 144 accredited medical schools contained a department of obstetrics and gynecology with a chair; 101 a gynecologic oncology division with a director; 98 a clinical cancer center with a director. Women were overrepresented in academic faculty roles compared to the US workforce (66 vs 57%, p < 0.01) but underrepresented in all leadership roles (p < 0.01). Departments with women chairs were more likely to have >50% women faculty (90.2 vs 9.8%, p < 0.01); and have larger faculties (80.4 vs 19.6% >20 faculty, p = 0.02). The cancer center director gender did not correlate to departmental characteristics. A surgically focused chair was also associated with >50% women faculty (85.7 vs 68.3%, p = 0.03); faculty size >20 (85.7 vs 61.4%, p < 0.01); and a woman gynecologic oncology division director (57.6 vs 29.4%, p < 0.01; 68.4 vs 31.7%, p < 0.01) and gynecologic oncology fellowship (50 vs 30.4%, p < 0.01; 59.1 vs 32%, p < 0.01). Gynecologic oncology leadership within cancer centers was below expected when incidence and mortality to leadership ratios were examined (p < 0.01, p < 0.01). CONCLUSION: Within academic medical schools, women remain under-represented in obstetrics and gynecology departmental and cancer center leadership. Potential benefits to gynecologic oncology divisions of inclusion women and surgically focused leadership were identified.
