ABSTRACT
At first recurrence, platinum-sensitive ovarian cancer (PSOC) is frequently treated with platinum-based chemotherapy doublets plus bevacizumab, then single-agent bevacizumab. Most patients' disease progresses within a year after chemotherapy, emphasizing the need for novel strategies. Mirvetuximab soravtansine-gynx (MIRV), an antibody-drug conjugate, comprises a folate receptor alpha (FRα)-binding antibody and tubulin-targeting payload (maytansinoid DM4). In FRα-high PSOC, MIRV plus bevacizumab previously showed promising efficacy (objective response rate, 69% [95% CI: 41-89]; median progression-free survival, 13.3 months [95% CI: 8.3-18.3]; median duration of response, 12.9 months [95% CI: 6.5-15.7]) and safety. The Phase III randomized GLORIOSA trial will evaluate MIRV plus bevacizumab vs. bevacizumab alone as maintenance therapy in patients with FRα-high PSOC who did not have disease progression following second-line platinum-based doublet chemotherapy plus bevacizumab.Clinical Trial Registration: ClinicalTrials.gov ID: NCT05445778; GOG.org ID: GOG-3078; ENGOT.ESGO.org ID: ENGOT-ov76.
Most patients with ovarian cancer are initially treated with platinum-based chemotherapy. If the cancer reappears/recurs after more than 6 months following this therapy, it is called platinum-sensitive ovarian cancer (PSOC). Patients with PSOC usually receive additional platinum-based chemotherapy along with bevacizumab, a drug that reduces tumor growth by decreasing its blood supply. If patients improve or are stable on this therapy, they are usually kept on bevacizumab alone for 'maintenance therapy'. Unfortunately, this maintenance therapy does not work long-term in all patients, so better long-term treatments are needed. The GLORIOSA (NCT05445778) clinical trial will compare maintenance therapy with bevacizumab alone to maintenance therapy with bevacizumab plus a drug called mirvetuximab soravtansine-gynx (MIRV) to determine which therapy leads to better results in patients with PSOC. MIRV is made up of an antibody that binds to a specific protein (folate receptor alpha [FRα]) on cancer cells to directly deliver a cancer-killing drug. MIRV received US FDA approval to be used as a therapy for patients with ovarian cancer who are resistant to platinum-based chemotherapy and express high levels of FRα. The GLORIOSA trial will study maintenance therapy with MIRV plus bevacizumab in patients with PSOC who have not had cancer progression after second-line platinum-based chemotherapy plus bevacizumab, and whose cancer expresses high amounts of FRα. The main purpose of this trial is to determine if MIRV plus bevacizumab leads to better patient survival and decreases cancer growth and spread when compared with bevacizumab alone.
ABSTRACT
OBJECTIVE: Due to limited data on homologous recombination deficiency (HRD) in older patients (≥ 70 years) with advanced stage high grade serous ovarian cancer (HGSC), we aimed to determine the rates of HRD at diagnosis in this age group. METHODS: From the Phase 3 trial VELIA the frequency of HRD and BRCA1/2 pathogenic variants (PVs) was compared between younger (< 70 years) and older participants. HRD and somatic(s) BRCA1/2 pathogenic variants (PVs) were determined at diagnosis using Myriad myChoice® CDx and germline(g) BRCA1/2 PVs using Myriad BRACAnalysis CDx®. HRD was defined if a BRCA PV was present, or the genomic instability score (GIS) met threshold (GIS ≥ 33 & ≥ 42 analyzed). RESULTS: Of 1140 participants, 21% were ≥ 70 years. In total, 26% (n = 298) had a BRCA1/2 PV and HRD, 29% (n = 329) were HRD/BRCA wild-type, 33% (n = 372) non-HRD, and 12% HR-status unknown (n = 141). HRD rates were higher in younger participants, 59% (n = 476/802), compared to 40% (n = 78/197) of older participants (GIS ≥ 42) [p < 0.001]; similar rates demonstrated with GIS ≥ 33, 66% vs 48% [p < 0.001]. gBRCA PVs observed in 24% younger vs 8% of older participants (p < 0.001); sBRCA in 8% vs 10% (p = 0.2559), and HRD (GIS ≥ 42) not due to gBRCA was 35% vs 31% (p = 0.36). CONCLUSIONS: HRD frequency was similar in participants aged < 70 and ≥ 70 years (35% vs 31%) when the contribution of gBRCA was excluded; rates of sBRCA PVs were also similar (8% v 10%), thus underscoring the importance of HRD and BRCA testing at diagnosis in older patients with advanced HGSC given the therapeutic implications.

BACKGROUND: Patients with advanced/recurrent endometrial cancer have a poor prognosis and limited treatment options. Biomarkers such as tumor protein 53 (TP53) in endometrial cancer can integrate novel strategies for improved and individualized treatment that could impact patient outcomes. In an exploratory analysis of the phase III ENGOT-EN5/GOG-3055/SIENDO study of selinexor maintenance monotherapy 80 mg in advanced/recurrent endometrial cancer, a pre-specified subgroup of patients with TP53 wild type (wt) endometrial cancer showed preliminary activity at long-term follow-up with a generally manageable safety profile (median progression-free survival 27.4 months vs 5.2 months placebo, HR=0.41). PRIMARY OBJECTIVE: To evaluate the efficacy of selinexor compared with placebo as maintenance therapy in patients with advanced or recurrent TP53wt endometrial cancer. STUDY HYPOTHESIS: Selinexor administered at 60 mg weekly as maintenance therapy will show manageable safety and maintain efficacy in patients with TP53wt advanced/recurrent endometrial cancer after systemic therapy versus placebo. TRIAL DESIGN: This is a prospective, multicenter, double-blind, placebo-controlled, randomized phase III study designed to evaluate the efficacy and safety of selinexor as a maintenance therapy in patients with advanced or recurrent TP53wt endometrial cancer. MAJOR INCLUSION/EXCLUSION CRITERIA: Eligible patients must have histologically confirmed endometrial cancer, TP53wt confirmed by next-generation sequencing, completed at least 12 weeks of platinum-based therapy with or without immunotherapy, with confirmed partial response or complete response, and primary Stage IV disease or at first relapse. PRIMARY ENDPOINT: The primary endpoint is investigator-assessed progression-free survival per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 in the intent-to-treat population. SAMPLE SIZE: A total of 220 patients will be enrolled. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual is expected to be completed in 2024 with presentation of results in 2025. TRIAL REGISTRATION: NCT05611931.

BACKGROUND: The objective was to compare sequencing strategies for treatment of advanced endometrial carcinoma. METHODS: Patients were eligible if they had FIGO 2009 Stage III or IVA endometrial carcinoma or Stage I or II serous or clear cell endometrial carcinoma and positive cytology. Patients were randomized to: Cisplatin 50 mg/m2 IV Days 1 and 29 plus radiation followed by Carboplatin AUC 5 or 6 plus Paclitaxel 175 mg/m2 q 21 days for 4 cycles (chemoRT then chemo) vs. Carboplatin AUC 6 plus Paclitaxel 175 mg/m2 q 21 days for 3 cycles followed by radiation followed by Carboplatin AUC 5 or 6 plus Paclitaxel 175 mg/m2 q 21 days for 3 cycles (sandwich therapy). Futility analysis was planned. The primary objective was to determine if chemoRT then chemo improves recurrence-free survival (RFS) compared to sandwich therapy. RESULTS: Of the 48 patients enrolled at 8 sites, 42 patients were eligible for futility analysis, and the trial was closed early. The median follow-up was 30.9 months. The 3-year RFS was 85.7% (95% confidence interval [CI], 62 to 95) in the chemoRT then chemo arm and 73.4% (95% CI, 43 to 89) in the sandwich therapy group (p = 0.58). The 3-year overall survival (OS) was 88.4% (95% CI, 61 to 97) in the chemoRT then chemo arm and 80.9% (95% CI, 51 to 93) in the sandwich therapy group (p = 0.55). CONCLUSION: There was no observed significant difference between chemoRT then chemo compared to sandwich therapy in terms of RFS, OS, or adverse events, although the trial was underpowered and closed early due to low accrual.

Standard single-agent nonplatinum chemotherapy provides only modest benefit in a small proportion of patients with platinum-resistant/-refractory ovarian cancer, with objective response rates of 6-20% and progression-free survival of ≈3-4 months. Nemvaleukin alfa (nemvaleukin, ALKS 4230) is a novel cytokine designed to capture and expand the therapeutic potential of high-dose interleukin-2 (IL-2) while mitigating its associated toxicity issues. Nemvaleukin preferentially activates cytotoxic CD8+ T cells and natural killer cells with minimal, non-dose-dependent effects on CD4+ regulatory T cells. The global, randomized, open-label, phase III ARTISTRY-7 trial will compare efficacy and safety of nemvaleukin plus pembrolizumab with chemotherapy in patients with platinum-resistant ovarian cancer. The primary end point is investigator-assessed progression-free survival. Clinical Trial Registration: GOG-3063; ENGOT-OV68; NCT05092360 (ClinicalTrials.gov).
In many patients with ovarian cancer who are treated with platinum-based chemotherapy, the tumor comes back after a few months and fails to respond to repeated treatment. This type of disease is called platinum-resistant ovarian cancer (PROC). Researchers are searching for new medicines to help more patients with PROC. One treatment approach that has shown promise in different cancers is called immunotherapy. These medicines work by helping the body's immune system attack cancer cells. One of the immunotherapies being studied is called nemvaleukin. It is designed to trigger specific immune responses that may result in the immune system attacking cancer cells while potentially avoiding other immune responses that can block the attack or cause certain unwanted side effects. Nemvaleukin is being studied in a variety of cancer types. In a worldwide clinical trial called ARTISTRY-7, researchers are investigating how nemvaleukin works in patients with PROC when given with another immunotherapy called pembrolizumab. Patients who participate in this trial will be randomly assigned to one of four treatment groups: the combination of nemvaleukin and pembrolizumab, nemvaleukin by itself, pembrolizumab by itself, or a type of chemotherapy selected by the treating physician. The main purpose of ARTISTRY-7 is to understand whether the combination of nemvaleukin and pembrolizumab helps patients with PROC live longer without their cancer getting worse. At the time of this writing, ARTISTRY-7 is open for new patients to join.

PURPOSE: ATHENA (ClinicalTrials.gov identifier: NCT03522246) was designed to evaluate rucaparib first-line maintenance treatment in a broad patient population, including those without BRCA1 or BRCA2 (BRCA) mutations or other evidence of homologous recombination deficiency (HRD), or high-risk clinical characteristics such as residual disease. We report the results from the ATHENA-MONO comparison of rucaparib versus placebo. METHODS: Patients with stage III-IV high-grade ovarian cancer undergoing surgical cytoreduction (R0/complete resection permitted) and responding to first-line platinum-doublet chemotherapy were randomly assigned 4:1 to oral rucaparib 600 mg twice a day or placebo. Stratification factors were HRD test status, residual disease after chemotherapy, and timing of surgery. The primary end point of investigator-assessed progression-free survival was assessed in a step-down procedure, first in the HRD population (BRCA-mutant or BRCA wild-type/loss of heterozygosity high tumor), and then in the intent-to-treat population. RESULTS: As of March 23, 2022 (data cutoff), 427 and 111 patients were randomly assigned to rucaparib or placebo, respectively (HRD population: 185 v 49). Median progression-free survival (95% CI) was 28.7 months (23.0 to not reached) with rucaparib versus 11.3 months (9.1 to 22.1) with placebo in the HRD population (log-rank P = .0004; hazard ratio [HR], 0.47; 95% CI, 0.31 to 0.72); 20.2 months (15.2 to 24.7) versus 9.2 months (8.3 to 12.2) in the intent-to-treat population (log-rank P < .0001; HR, 0.52; 95% CI, 0.40 to 0.68); and 12.1 months (11.1 to 17.7) versus 9.1 months (4.0 to 12.2) in the HRD-negative population (HR, 0.65; 95% CI, 0.45 to 0.95). The most common grade ≥ 3 treatment-emergent adverse events were anemia (rucaparib, 28.7% v placebo, 0%) and neutropenia (14.6% v 0.9%). CONCLUSION: Rucaparib monotherapy is effective as first-line maintenance, conferring significant benefit versus placebo in patients with advanced ovarian cancer with and without HRD.

The molecular etiology of uterine leiomyosarcoma (ULMS) is poorly understood, which accounts for the wide disparity in outcomes among women with this disease. We examined and compared the molecular profiles of ULMS and normal myometrium (NL) to identify clinically relevant molecular subtypes. Discovery cases included 29 NL and 23 ULMS specimens. RNA was hybridized to Affymetrix U133A 2.0 transcription microarrays. Differentially expressed genes and pathways were identified using standard methods. Fourteen NL and 44 ULMS independent archival samples were used for external validation. Molecular subgroups were correlated with clinical outcome. Pathway analyses of differentially expressed genes between ULMS and NL samples identified overrepresentation of cell cycle regulation, DNA repair, and genomic integrity. External validation confirmed differential expression in 31 genes (P < 4.4 × 10(-4), Bonferroni corrected), with 84% of the overexpressed genes, including CDC7, CDC20, GTSE1, CCNA2, CCNB1, and CCNB2, participating in cell cycle regulation. Unsupervised clustering of ULMS identified two clades that were reproducibly associated with progression-free (median, 4.0 vs 26.0 months; P = .02; HR, 0.33) and overall (median, 18.2 vs 77.2 months; P = .04; HR, 0.33) survival. Cell cycle genes play a key role in ULMS sarcomagenesis, providing opportunities for therapeutic targeting. Reproducible molecular subtypes associated with clinical outcome may permit individualized adjuvant treatment after clinical trial validation.

OBJECTIVE: To compare survival outcomes for patients with advanced epithelial ovarian cancer (EOC) who received primary intravenous/intraperitoneal (IV/IP) chemotherapy to those who received IV followed by consolidation (treatment given to patients in remission) IP chemotherapy. METHODS: Data were analyzed and compared for all patients with stage III-IV EOC who underwent optimal primary cytoreduction (residual disease ≤ 1 cm) followed by cisplatin-based consolidation IP chemotherapy (1/2001-12/2005) or primary IV/IP chemotherapy (1/2005-7/2011). RESULTS: We identified 224 patients; 62 (28%) received IV followed by consolidation IP chemotherapy and 162 (72%) received primary IV/IP chemotherapy. The primary IP group had significantly more patients with serous tumors. The consolidation IP group had a significantly greater median preoperative platelet count, CA-125, and amount of ascites. There were no differences in residual disease at the end of cytoreduction between both groups. The median progression-free survival (PFS) was greater for the primary IP group; however, this did not reach statistical significance (23.7 months vs 19.7 months; HR 0.78; 95% CI, 0.57-1.06; p=0.11). The median overall survival (OS) was significantly greater for the primary IP group (78.8 months vs 57.5 months; HR 0.56; 95% CI, 0.38-0.83; p=0.004). On multivariate analysis, after adjusting for confounders, the difference in PFS was not significant (HR 0.78; 95% CI, 0.56-1.11; p=0.17), while the difference in OS remained significant (HR 0.59; 95% CI, 0.39-0.89; p=0.01). CONCLUSIONS: In our study, primary IV/IP chemotherapy was associated with improved OS compared to IV followed by consolidation IP chemotherapy in patients with optimally cytoreduced advanced EOC.

ABSTRACT
OBJECTIVE: We propose a new staging system for stage I endometrial cancer and compare its performance to the 1988 and 2009 International Federation of Gynecology and Obstetrics (FIGO) systems. METHODS: We analyzed patients with 1988 FIGO stage I endometrial cancer from January 1993 to August 2011. Low-grade carcinoma consisted of endometrioid grade 1 to grade 2 lesions. High-grade carcinoma consisted of endometrioid grade 3 or nonendometrioid carcinomas (serous, clear cell, and carcinosarcoma). The proposed system is as follows:IA. Low-grade carcinoma with less than half myometrial invasionIB. High-grade carcinoma with no myometrial invasionIC. Low-grade carcinoma with half or greater myometrial invasionID. High-grade carcinoma with any myometrial invasion RESULTS: Data from 1843 patients were analyzed. When patients were restaged with our proposed system, the 5-year overall survival significantly differed (P < 0.001): IA1, 96.7%; IA2, 92.2%; IB1, 92.2%; IB2, 76.4%; IC1, 83.9%; IC2, 78.6%; ID1, 81.1%; and ID2, 68.8%. The bootstrap-corrected concordance probability estimate for the proposed system was 0.627 (95% confidence interval, 0.590-0.664) and was superior to the concordance probability estimate of 0.530 (95% confidence interval, 0.516-0.544) for the 2009 FIGO system. CONCLUSIONS: By incorporating histological subtype, grade, myometrial invasion, and whether lymph nodes were removed, our proposed system for stage I endometrial cancer has a superior predictive ability over the 2009 FIGO staging system and provides a novel binary grading system (low-grade including endometrioid grade 1-2 lesions; high-grade carcinoma consisting of endometrioid grade 3 carcinomas and nonendometrioid carcinomas).

OBJECTIVE: The objectives of the study are to evaluate which clinicopathologic factors influenced overall survival (OS) in endometrial carcinoma and to determine if the surgical effort to assess para-aortic (PA) lymph nodes (LNs) at initial staging surgery impacts OS. METHODS: All patients diagnosed with endometrial cancer from 1/1993-12/2011 who had LNs excised were included. PALN assessment was defined by the identification of one or more PALNs on final pathology. A multivariate analysis was performed to assess the effect of PALNs on OS. A form of recursive partitioning called classification and regression tree (CART) analysis was implemented. Variables included: age, stage, tumor subtype, grade, myometrial invasion, total LNs removed, evaluation of PALNs, and adjuvant chemotherapy. RESULTS: The cohort included 1920 patients, with a median age of 62 years. The median number of LNs removed was 16 (range, 1-99). The removal of PALNs was not associated with OS (P=0.450). Using the CART hierarchically, stage I vs. stages II-IV and grades 1-2 vs. grade 3 emerged as predictors of OS. If the tree was allowed to grow, further branching was based on age and myometrial invasion. Total number of LNs removed and assessment of PALNs as defined in this study were not predictive of OS. CONCLUSION: This innovative CART analysis emphasized the importance of proper stage assignment and a binary grading system in impacting OS. Notably, the total number of LNs removed and specific evaluation of PALNs as defined in this study were not important predictors of OS.

OBJECTIVE: To describe the incidence of low-volume ultrastage-detected metastases in sentinel lymph nodes (SLNs) identified at surgical staging for endometrial carcinoma and to correlate it with depth of myoinvasion and tumor grade. METHODS: We reviewed all patients who underwent primary surgery for endometrial carcinoma with successful mapping of at least one SLN at our institution from September 2005 to December 2011. All patients underwent a cervical injection for mapping. The SLN ultrastaging protocol involved cutting an additional 2 adjacent 5-µm sections at each of 2 levels, 50-µm apart, from each paraffin block lacking metastatic carcinoma on routine hematoxylin and eosin (H&E) staining. At each level, one slide was stained with H&E and with immunohistochemistry (IHC) using anticytokeratin AE1:AE3.Micrometastases (tumor deposits >0.2 mm and ≤2 mm) and isolated tumor cells (≤0.2 mm) were classified as low-volume ultrastage-detected metastases if pathologic ultrastaging was the only method allowing detection of such nodal disease. RESULTS: Of 508 patients with successful mapping, 413 patients (81.3%) had endometrioid carcinoma. Sixty-four (12.6%) of the 508 patients had positive nodes: routine H&E detected 35 patients (6.9%), ultrastaging detected an additional 23 patients (4.5%) who would have otherwise been missed (4 micrometastases and 19 isolated tumor cells), and 6 patients (1.2%) had metastatic disease in their non-SLNs. The incidence rates of low-volume ultrastage-detected nodal metastases in patients with grades 1, 2, and 3 tumors were 3.8%, 3.4%, and 6.9%, respectively. The frequency rates of low-volume ultrastage-detected metastases in patients with a depth of myoinvasion of 0, less than 50%, and 50% or more were 0.8%, 8.0%, and 7.4%, respectively. Lymphovascular invasion was present in 20 (87%) of the cases containing low-volume ultrastage-detected metastases in the lymph nodes. CONCLUSIONS: Sentinel lymph node mapping with pathologic ultrastaging in endometrial carcinoma detects additional low-volume metastases (4.5%) that would otherwise go undetected with routine evaluations. Our data support the incorporation of pathologic ultrastaging of SLNs in endometrial carcinoma with any degree of myoinvasion. The oncologic significance of low-volume nodal metastases requires long-term follow-up.

OBJECTIVES: High-grade serous ovarian cancer (HGSOC) mostly presents at an advanced stage and has a low overall survival rate. However, a subgroup of patients are seemingly cured after standard initial therapy. We hypothesize that the molecular profiles of these patients vary from long-term survivors who recur. METHODS: Patients with advanced HGSOC who underwent primary cytoreductive surgery and platinum-based chemotherapy were identified from The Cancer Genome Atlas (TCGA) and institutional (MSKCC) samples. A curative-intent group was defined by recurrence-free survival of >5years. A long-term recurrent group was composed of patients who recurred but survived >5years. RNA was hybridized to Affymetrix U133A transcription microarrays. The NanoString nCounter gene expression system was used for validation in an independent patient population. RESULTS: In 30 curative and 84 recurrent patients, class comparison identified twice as many differentially expressed probes between the groups than expected by chance alone. TCGA and MSKCC data sets had 19 overlapping genes. Pathway analyses identified over-represented networks that included nuclear factor kappa B (NFkB) transcription and extracellular signal-regulated kinase (ERK) signaling. External validation was performed in an independent population of 28 curative and 38 recurrent patients. Three genes (CYP4B1, CEPT1, CHMP4A) in common between our original data sets remained differentially expressed in the external validation data. CONCLUSIONS: There are distinct transcriptional elements in HGSOC from patients likely to be cured by standard primary therapy. Three genes have withstood rigorous validation and are plausible targets for further study, which may provide insight into molecular features associated with long-term survival and chemotherapy resistance mechanisms.

OBJECTIVE: The purpose of this study was to describe the location of disease at the time of death of patients with endometrial cancer who died of their disease. METHODS: All patients with a diagnosis of endometrial cancer from January 1993 through December 2010 were included. Histologic classification was either endometrioid or high-risk (HR) endometrial cancer. Patients who died were divided into 3 groups: dead of disease (DOD), dead of other causes (DOO), and dead lost to follow-up. Patterns of disease spread at death were documented from the most recent examination and imaging studies. RESULTS: We identified 2513 patients. The median age at diagnosis was 62 years. Histologic findings were endometrioid endometrial cancer, 1949 patients (78%); and HR endometrial cancer, 54 patients (22%). The 1988 International Federation of Gynecology and Obstetrics stages were: stage I, 1763 patients (70%); stage II, 145 patients (6%); stage III, 416 patients (17%); and stage IV, 189 patients (8%). At the time of this study, 1867 patients (74%) had no evidence of disease, 232 patients (9%) were alive with disease, and 414 patients (16%) were dead. Of the 16% of patients who were dead, 224 (9%) of the 2513 patients were DOD, 84 (3%) of the 2513 patients were dead of other disease, and 106 (4%) of the 2513 patients were dead lost to follow-up. Of the 224 patients who were DOD, the locations of the disease at the time of death were pelvic, 23 patients (10%); abdominal, 83 patients (37%); and distant, 118 patients (53%). There was no significant difference in the pattern of location of disease between the endometrioid and HR histologies (P = 0.36). CONCLUSIONS: These data suggest that death from endometrial cancer is largely due to abdominal (liver) and distant (lung) metastases, and this pattern of disease seems similar in the endometrioid and HR histologies. Most of the patients who died of their disease had metastases beyond the pelvis at the time of death.

OBJECTIVE: GOG study 172 demonstrated improved progression-free (PFS) and overall (OS) survival for patients with stage III optimally debulked ovarian and peritoneal carcinoma treated with IV/IP paclitaxel and IP cisplatin compared to standard IV therapy. The inpatient administration, toxicity profile, and limited completion rate have been blamed for the lack of acceptance and widespread use of this regimen. We sought to evaluate the PFS, OS, toxicity, and completion rate of a modified outpatient IP regimen. METHODS: Using a prospectively maintained database, we evaluated the outcomes of patients who underwent primary optimal cytoreduction for stage III ovarian, tubal, or peritoneal carcinoma followed by IV/IP chemotherapy from 1/05-3/09. Our modified regimen was as follows: IV paclitaxel (135 mg/m(2)) over 3h on day 1, IP cisplatin (75 mg/m(2)) on day 2, and IP paclitaxel (60 mg/m(2)) on day 8, given every 21 days for 6 cycles. RESULTS: We identified 102 patients who initiated the modified IV/IP regimen and completed chemotherapy. The median follow-up was 43 months. The median age at diagnosis was 57 years (range, 23-76). Primary disease site was: ovary, 77 (75%); fallopian tube, 13 (13%); peritoneum, 12 (12%). FIGO stage was: IIIA, 8 (8%); IIIB, 4 (4%); IIIC, 90 (88%). Residual disease after cytoreduction was: none, 58 (57%); ≤ 1 cm, 44 (43%). The most frequent grade 3/4 toxicities were: neutropenia, 12 (12%); gastrointestinal, 8 (8%); neurologic, 6 (6%). Eighty-two (80%) of 102 patients completed 4 or more cycles of IV/IP therapy; 56 (55%) completed all 6 cycles. The median PFS and OS were 29 and 67 months, respectively. CONCLUSIONS: By modifying the GOG 172 treatment regimen, convenience, toxicity, and tolerability appear improved, with survival outcomes similar to those of GOG 172. This modified IV/IP regimen warrants further study.

OBJECTIVE: To determine the false-negative rate of a surgical sentinel lymph node (SLN) mapping algorithm that incorporates more than just removing SLNs in detecting metastatic endometrial cancer. METHODS: A prospective database of all patients who underwent lymphatic mapping for endometrial cancer was reviewed. Cervical injection of blue dye was used in all cases. The surgical algorithm is as follows: 1) peritoneal and serosal evaluation and washings; 2) retroperitoneal evaluation including excision of all mapped SLNs and suspicious nodes regardless of mapping; and 3) if there is no mapping on a hemi-pelvis, a side-specific pelvic, common iliac, and interiliac lymph node dissection (LND) is performed. Paraaortic LND is performed at the attendings' discretion. The algorithm was retrospectively applied. RESULTS: From 9/2005 to 4/2011, 498 patients received a blue dye cervical injection for SLN mapping. At least one LN was removed in 95% of cases (474/498); at least one SLN was identified in 81% (401/498). SLN correctly diagnosed 40/47 patients with nodal metastases who had at least one SLN mapped, resulting in a 15% false-negative rate. After applying the algorithm, the false-negative rate dropped to 2%. Only one patient, whose LN spread would not have been caught by the algorithm, had an isolated positive right paraaortic LN with a negative ipsilateral SLN and pelvic LND. CONCLUSIONS: Satisfactory SLN mapping in endometrial cancer requires adherence to a surgical SLN algorithm and goes beyond just the removal of blue SLNs. Removal of any suspicious node along with side-specific lymphadenectomy for failed mapping are an integral part of this algorithm. Further validation of the false-negative rate of this algorithm is necessary.

OBJECTIVE: To develop a nomogram based on established prognostic factors to predict the probability of 5-year disease-specific mortality after primary surgery for patients with all stages of epithelial ovarian cancer (EOC) and compare the predictive accuracy with the currently used International Federation of Gynecology and Obstetrics (FIGO) staging system. METHODS: Using a prospectively kept database, we identified all patients with EOC who had their primary surgery at our institution between January 1996 and December 2004. Disease-specific mortality was estimated using the Kaplan-Meier method. Twenty-eight clinical and pathologic factors were analyzed. Significant factors on univariate analysis were included in the Cox proportional hazards regression model, which identified factors utilized in the nomogram. The concordance index (CI) was used as an accuracy measure, with bootstrapping to correct for optimistic bias. Calibration plots were constructed. RESULTS: A total of 478 patients with EOC were included. The most predictive nomogram was constructed using seven variables: age, FIGO stage, residual disease status, preoperative albumin level, histology, family history suggestive of hereditary breast/ovarian cancer (HBOC) syndrome, and American Society of Anesthesiologists (ASA) status. This nomogram was internally validated using bootstrapping and shown to have excellent calibration with a bootstrap-corrected CI of 0.714. The CI for FIGO staging alone was significantly less at 0.62 (P=0.002). CONCLUSION: We have developed an all-stage nomogram to predict 5-year disease-specific mortality after primary surgery for epithelial ovarian cancer. This tool is more accurate than FIGO staging and should be useful for patient counseling, clinical trial eligibility, postoperative management, and follow-up.

OBJECTIVE: To determine the relative effect and quantify the impact of multiple prognostic variables on median overall survival time among cohorts of patients with advanced or recurrent endometrial cancer undergoing cytoreductive surgery. METHODS: Fourteen retrospective cohorts with advanced or recurrent endometrial cancer (672 patients) meeting study inclusion criteria were identified. Univariate analysis was used to assess the effect on median overall survival time of multiple variables. The limited number of studies available made multivariate analysis impractical. RESULTS: Statistically significant clinical variables associated with median overall survival time were the proportion of patients undergoing complete surgical cytoreduction, adjuvant radiation, or receiving adjuvant chemotherapy. Cohort median overall survival time was positively associated with increasing proportion of patients undergoing complete surgical cytoreduction (each 10% increase improving survival by 9.3 months, p=0.04) and receiving post-operative radiation therapy (each 10% increase improving survival by 11.0 months, p=0.004), while an increasing proportion of patients receiving chemotherapy was negatively associated with survival (each 10% increase decreasing survival by 10.4 months, p=0.007). CONCLUSIONS: The current analysis suggests that among patients with advanced or recurrent endometrial cancer, complete cytoreduction to no gross residual disease is associated with superior overall survival outcome. The unexpected correlation between treatment modality and survival may be a surrogate marker for more precise factors such as location of disease, performance status, or cytoreductive status post-operatively, which may have influenced the decision to administer adjuvant radiation versus chemotherapy and were not able to be controlled for given the limitations of the extracted data.

OBJECTIVE: To determine the utility of endocervical curettage (ECC) at cervical conization for predicting residual or recurrent dysplasia and to evaluate differences in management between general gynecologists and gynecologic oncologists. STUDY DESIGN: From February 1999 to November 2007, 192 patients with high-grade dysplasia on conization were retrospectively identified. Data were analyzed for 54 patients who underwent repeat conization or hysterectomy to evaluate predictors of disease. Data for all patients were analyzed based on provider. RESULTS: Among patients who underwent secondary procedures, 68.5% (37/54) had residual or recurrent disease. Eighty-six percent of patients with a positive ECC had residual or recurrent disease compared to 48% of patients with a negative ECC (OR 6.91, CI 1.595-30.00, p=0.01). Among all patients, 77% (148/192) were managed by a generalist, and 23% (44/192) by a gynecologic oncologist. Oncologists were significantly more likely to perform a hysterectomy (45.5% vs. 14.2%, OR 5.04, CI 2.38-10.69, p<0.0001). CONCLUSION: Endocervical curettage at the time of conization with high-grade dysplasia is a simple and reliable predictor of residual or recurrent disease and should be performed routinely. Gynecologic oncologists are more likely than general gynecologists to perform a hysterectomy in the management of high-grade dysplasia on conization.
