Venoarterial Extracorporeal Membrane Oxygenation to Facilitate Transcutaneous Mitral Valve Replacement in Critical Mitral Stenosis.

Biological mitral valve restenosis after replacement in rheumatic heart disease is a rare complication. This case illustrates venoarterial extracorporeal membrane oxygenation to facilitate transcatheter mitral valve replacement in a patient with suprasystemic pulmonary pressure and cardiogenic shock with multiorgan failure secondary to critical mitral stenosis of a bioprosthetic valve.(Level of Difficulty: Advanced.).

Disease Distribution at Presentation Impacts Benefit of IP Chemotherapy Among Patients with Advanced-Stage Ovarian Cancer.

BACKGROUND: Ovarian cancer with miliary disease spread is an aggressive phenotype lacking targeted management strategies. We sought to determine whether adjuvant intravenous/intraperitoneal (IV/IP) chemotherapy is beneficial in this disease setting. METHODS: Patient/tumor characteristics and survival data of patients with stage IIIC epithelial ovarian cancer who underwent optimal primary debulking surgery from 01/2010 to 11/2014 were abstracted from records. Chi-square and Mann-Whitney U tests were used to compare categorical and continuous variables. The Kaplan-Meier method was used to estimate survival curves, and outcomes were compared using log-rank tests. Factors significant on univariate analysis were combined into multivariate logistic regression survival models. RESULTS: Among 90 patients with miliary disease spread, 41 (46%) received IV/IP chemotherapy and 49 (54%) received IV chemotherapy. IV/IP chemotherapy, compared with IV chemotherapy, resulted in improved progression-free survival (PFS; 23.0 versus 12.0 months; p = 0.0002) and overall survival (OS; 52 versus 36 months; p = 0.002) in patients with miliary disease. Among 78 patients with nonmiliary disease spread, 23 (29%) underwent IV/IP chemotherapy and 55 (71%) underwent IV chemotherapy. There was no PFS or OS benefit associated with IV/IP chemotherapy over IV chemotherapy in these patients. On multivariate analysis, IV/IP chemotherapy was associated with improved PFS (HR, 0.28; 95% CI 0.15-0.53) and OS (HR, 0.33; 95% CI 0.18-0.61) in patients with miliary disease compared with those with nonmiliary disease (PFS [HR, 1.53; 95% CI 0.74-3.19]; OS [HR, 1.47; 95% CI 0.70-3.09]). CONCLUSIONS: Adjuvant IV/IP chemotherapy was associated with oncologic benefit in miliary disease spread. This survival benefit was not observed in nonmiliary disease.

Neoadjuvant chemotherapy does not disproportionately influence post-operative complication rates or time to chemotherapy in obese patients with advanced-stage ovarian cancer.

OBJECTIVES: To determine whether neoadjuvant chemotherapy (NACT) disproportionately benefits obese patients. METHODS: Data were collected from stage IIIC-IV ovarian cancer patients treated between 01/2010-07/2015. We performed univariate/multivariate logistic regression analyses with post-operative infection, readmission, any postoperative complication, and time to chemotherapy as outcomes. An interaction term was included in models, to determine if the effect of NACT on post-operative complications was influenced by obesity status. RESULTS: Of 507 patients, 115 (22.6%) were obese and 392 (77.3%) were non-obese (obese defined as BMI ≥30). Among obese patients undergoing primary debulking surgery (PDS) vs. NACT, rates of postoperative infection were 42.9% vs. 30.8% (p = 0.12), 30-day readmission 30.2% vs. 11.5% (p < 0.02), and any post-operative complication were 44.4% vs 30.8% (p = 0.133). Among non-obese patients undergoing PDS vs. NACT, rates of post-operative infection were 20.0% vs. 12.9% (p = 0.057), 30-day readmission 16.9% vs. 9.2% (p = 0.02), and any post-operative complication were 19.4% vs 28% (p = 0.044). Obesity was associated with post-operative infection (OR 2.3; 95%CI 1.22-4.33), 30-day readmission/reoperation (OR 2.27; 95%CI 1.08-3.21) and the development of any post-operative complication (OR 2.1; CI 1.13-3.74). However, there was not a significant interaction between obesity and NACT in any of the models predicting post-operative complications. CONCLUSIONS: The decision to use NACT should not be predicated on obesity alone, as the reduction in post-operative complications in obese patients is similar to non-obese patients.

Determining the optimal duration for premature ventricular contraction monitoring.

BACKGROUND: Premature ventricular contractions (VPC) have hour-to-hour and day-to-day variation. High VPC burden correlates with cardiomyopathy. OBJECTIVE: To determine the optimal duration for ambulatory electrocardiogram monitoring for accurate assessment of VPC burden. METHODS: Our group performed a retrospective analysis on patch monitors used for any indication with overall VPC burden ≥5.0% between February 1, 2016, and February 1, 2020. We generated cumulative daily VPC averages for each day of wear and performed linear regression analysis between each cumulative daily average and overall burden. Patients were divided into groups based on low or high VPC frequency, and the analysis was repeated. Split-sample validation was used to internally validate the overall prediction model. RESULTS: A total of 116 patches representing 107 patients (mean age: 64.5; female: 48%) were analyzed. Mean overall VPC burden was 13.4% ± 7.5% (range: 5.0%-42.0%). Day 1 R2 was 60%, P < .001, and continued to increase to R2 88%, P < .001 at day 14. Median percent and absolute error decreased from 22.70% (interquartile range [IQR]: 9.73-34.39) and 2.58% (IQR: 1.24-4.59) at day 1 to 5.62% (IQR: 2.82-8.39) and 0.55% (IQR: 0.28-1.05) at day 14. Patients with higher overall VPC frequencies achieved a more rapid rise in R2 relative to those with lower frequencies. Split-sample validation supported the internal validity of our linear regression prediction model. CONCLUSION: Mobile telemetry for a period of ∼7 days accurately reflects overall VPC burden. Measurement of VPC burden for only 24-48 hours may not accurately reflect total burden. Monitoring for 2 weeks or longer adds little additional VPC information.

A novel classification of residual disease after interval debulking surgery for advanced-stage ovarian cancer to better distinguish oncologic outcome.

BACKGROUND: Complete surgical resection affords the best prognosis at the time of interval debulking surgery. When complete surgical resection is unachievable, optimal residual disease is considered the next best alternative. Despite contradicting evidence on the survival benefit of interval debulking surgery if macroscopic residual disease remains, the current definition of "optimal" in patients undergoing interval debulking surgery is defined as largest diameter of disease measuring ≤1.0 cm, independent of the total volume of disease. OBJECTIVE: To examine the relationship between volume and anatomic distribution of residual disease and oncologic outcomes among patients with advanced-stage epithelial ovarian/fallopian tube/primary peritoneal carcinoma undergoing neoadjuvant chemotherapy then interval debulking surgery. For patients who did not undergo a complete surgical resection, a surrogate for volume of residual disease was used to assess oncologic outcomes. STUDY DESIGN: Patient demographics, operative characteristics, anatomic site of residual disease, and outcome data were collected from medical records of patients with International Federation of Gynecology and Obstetrics stage IIIC and IV epithelial ovarian cancer undergoing interval debulking surgery from January 2010 to July 2015. Among patients who did not undergo complete surgical resection but had ≤1 cm of residual disease, the number of anatomic sites (single location vs multiple locations) with residual disease was used as a surrogate for volume of residual disease. The effect of residual disease volume on progression-free survival and overall survival was evaluated. RESULTS: Of 270 patients undergoing interval debulking surgery, 173 (64.1%) had complete surgical resection, 34 (12.6%) had ≤1 cm of residual disease in a single anatomic location, 47 (17.4%) had ≤1 cm of residual disease in multiple anatomic locations, and 16 (5.9%) were suboptimally debulked. Median progression-free survival for each group was 14, 12, 10, and 6 months, respectively (P<.001). Median overall survival for each group was: 58, 37, 26, and 33 months, respectively (P<.001). CONCLUSION: Following interval debulking surgery, patients with complete surgical resection have the best prognosis, followed by patients with ≤1 cm single-anatomic location disease. In contrast, despite being considered "optimally debulked," patients with ≤1 cm multiple-anatomic location disease have a survival similar to suboptimally debulked patients.

Clinical characteristics and outcomes after bowel surgery and ostomy formation at the time of debulking surgery for advanced-stage epithelial ovarian carcinoma.

OBJECTIVE: There are limited data on clinical outcomes of patients with advanced-stage epithelial ovarian cancer who require ostomy formation at the time of either primary cytoreductive surgery or interval cytoreductive surgery. The objective of this study was to evaluate patients undergoing bowel surgery and ostomy formation after primary or interval surgery. METHODS: Patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC-IV epithelial ovarian cancer who underwent cytoreductive surgery between January 2010 and December 2014 were identified retrospectively. Patients with non-epithelial histology, low-grade serous histology or incomplete medical records were excluded. Demographic and clinical data were collected and analyzed. Age, stage, co-morbidity index, pre-operative CA125, pre-operative albumin, and Aletti surgical complexity score were included in a multivariable logistic regression model to assess independent associations with ostomy formation. RESULTS: A total of 554 patients were included in the study. Of these, 261 (47%) underwent primary cytoreduction and 293 (53%) underwent interval cytoreduction. Patients undergoing primary surgery were more likely to undergo bowel resection, compared with interval surgery patients (37.2% vs 14%, p<0.001). Of the 139 (25.1%) patients who underwent bowel surgery, 25 (18%) underwent ostomy formation (11 ileostomies and 14 colostomies). Rates of ostomy formation were similar between the groups (6.1% primary vs 3.1% interval, p=0.10). Patients undergoing ostomy formation were more likely to have longer mean operative time (335 vs 229 min, p<0.001) and undergo small and large bowel resections at the time of cytoreductive surgery (44% vs 14%, p<0.001). Multivariate analysis revealed that a high surgical complexity score was associated with ostomy formation. Of the patients who underwent ostomy formation, 13 (43.3%) underwent stoma reversal including 11 ileostomies and two colostomies. Median time to ostomy reversal was 7 months. CONCLUSION: Bowel surgery is more common among patients undergoing primary surgery as compared with interval surgery, but this does not result in an increased risk of ostomy formation.

Infection, thrombosis, and oncologic outcome after interval debulking surgery: Does perioperative blood transfusion matter?

OBJECTIVES: To determine whether perioperative red blood cell transfusion (PRBCT) affects infection, thrombosis, or survival rates in epithelial ovarian cancer (EOC) patients undergoing neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS). METHODS: Demographics, operative characteristics, and outcome data were abstracted from records of stage IIIC-IV EOC patients managed with NACT-IDS from 01/2010-07/2015. Associations of PRBCT with morbidity and oncologic outcomes were evaluated. RESULTS: Of 270 patients, 136 (50.4%) received PRBCT. Patients with preoperative anemia and higher estimated blood loss (EBL) were more likely to undergo PRBCT (OR,95%CI 1.80, 1.02-3.17) and (OR,95%CI 1.00, 1.002-1.004), respectively. There were no significant differences in PRBCT based on patient age, Charlson Comorbidity Index, or stage. When compared to low complexity operations, patients with moderate and high complexity surgeries were more likely to receive PRBCT (OR,95%CI 1.81, 1.05-3.09) and (OR,95%CI 2.25, 1.13-4.50), respectively. On univariate analysis, PRBCT was associated with intraabdominal infection (OR,95%CI 8.31, 1.03-67.41), but not wound complications (OR,95%CI 1.57, 0.76-3.23) or venous thromboembolism/pulmonary embolism (VTE/PE) (OR,95%CI 2.02, 0.49-8.23). After adjusting for surgical complexity and preoperative anemia, PRBCT was not independently associated with intraabdominal infection (OR,95%CI 7.66, 0.92-63.66), wound complications (OR,95%CI 1.70, 0.80-3.64), or VTE/PE (OR,95%CI 2.15, 0.51-9.09). When comparing patients undergoing PRBCT versus those who did not, there were no significant differences in median progression-free survival (PFS) or median overall survival (OS) on univariate analysis after adjusting for age, stage and residual disease. CONCLUSIONS: Among patients undergoing NACT-IDS, intraabdominal infection, wound complication and VTE/PE rates are similar, regardless of PRBCT. PRBCT does not impact PFS or OS.

Isolated para-aortic lymph node metastasis in FIGO stage IA2-IB2 carcinoma of the cervix: Revisiting the role of surgical assessment.

OBJECTIVES: To investigate the utility of para-aortic lymph node dissection among women undergoing radical hysterectomy and pelvic lymph adenectomy for FIGO Stage IA2-IB2 cervical cancer using the National Cancer Database (NCDB). METHODS: We identified patients with stage IA2-IB2 squamous cell, adenosquamous, or adenocarcinoma of the cervix diagnosed 2011-2014 in the NCDB. The primary outcome was the negative predictive value of histologically assessed pelvic lymph node status for para-aortic lymph node status among women undergoing pelvic and para-aortic lymph node dissection. We calculated probability of para-aortic lymph node metastasis conditional on pelvic lymph node status. Finally, we compared overall survival between patients undergoing para-aortic lymph node dissection and those in whom this procedure was omitted. RESULTS: A total of 3212 patients met study inclusion criteria, of whom 994 (30.9%) underwent para-aortic lymph node dissection. In this group, the risk of isolated para-aortic metastasis was 0.11%. The negative predictive value of surgically assessed pelvic lymph nodes to predict para-aortic lymph node status was 99.9% (95% CI 99.9-99.9). Among 93 patients with pelvic lymph node metastasis, 18 (19.4%) had concurrent para-aortic lymph node metastasis. There was no difference in overall survival between women undergoing pelvic and para-aortic lymph node dissection compared with those undergoing pelvic lymphadenectomy only (p = 0.69). CONCLUSIONS: In patients undergoing radical hysterectomy and pelvic lymphadenectomy for stage IA2-IB2 cervical cancer, para-aortic lymph node dissection is not warranted based on the low risk of isolated metastatic disease, and lack of survival benefit associated with the procedure.

Thirty-day unplanned hospital readmission in ovarian cancer patients undergoing primary or interval cytoreductive surgery: systematic literature review.

OBJECTIVES: Thirty-day readmission rate has been proposed as metric of quality and remains an ongoing clinical concern in the primary treatment of patients with advanced-stage ovarian epithelial ovarian cancer. We conducted a review of the literature to identify rates, risk factors, and predictors for 30-day readmission in this population. METHODS: A 10-year period MEDLINE (PubMed) search of English literature studies published between January 01, 2008-January 01, 2018 was performed to identify appropriate studies for review. RESULTS: Thirty -day readmission rates for ovarian cancer patients undergoing primary treatment ranged from 2.5-19.3%. Neoadjuvant chemotherapy and interval cytoreductive surgery (NACT-ICS) surgery was associated with lower readmission rates, when compared to primary debulking surgery (PDS). The most frequently reported adverse events resulting in readmission include inpatient management of ileus/small bowel obstruction, wound-related complications, and thromboembolic events. Readmission predictors included the presence of other medical comorbidities, re-operation, and major complications occurring after initial hospital discharge. Some studies reported lower rates of readmission and survival in patients treated by NACT-ICS. CONCLUSIONS: Policies and programs should be designed to measure short- and long-term outcomes in this patient population to avoid bias in assigning patients to NACT-ICS to maintain low 30-day readmission rates.

Moving beyond "complete surgical resection" and "optimal": Is low-volume residual disease another option for primary debulking surgery?

OBJECTIVES: To examine the relationship between volume of residual disease and oncologic outcomes among patients with advanced-stage epithelial ovarian/fallopian tube/primary peritoneal carcinoma undergoing primary debulking surgery (PDS). For patients that did not undergo a complete surgical resection (CSR), a surrogate for volume of residual disease was used to assess oncologic outcomes. METHODS: Medical records of patients with FIGO stage IIIC and IV epithelial ovarian/fallopian tube/primary peritoneal carcinoma undergoing PDS between January 2010 and November 2014 were reviewed. Patient demographics, operative characteristics, residual disease, anatomic site of residual disease and outcome data were collected. Among patients who did not undergo CSR, but had ≤1 cm of residual disease, the number of anatomic sites (single location vs. multiple locations) with residual disease was utilized as a surrogate for volume of residual disease. The effect of residual disease volume on progression-free survival (PFS) and overall survival (OS) was evaluated. RESULTS: Of 240 patients undergoing PDS, 94 (39.2%) had CSR, 41 (17.1%) had ≤1 cm of residual disease confined to a single anatomic location (≤1 cm-SL), 67 (27.9%) had ≤1 cm of residual disease in multiple anatomic locations (≤1 cm-ML) and 38 (15.8%) were sub-optimally (SO) debulked. Median PFS for CSR, ≤1 cm-SL, ≤1 cm-ML and SO-debulked were: 23, 19, 13 and 10 months, respectively (p < 0.001). Median OS for CSR, ≤1 cm-SL, ≤1 cm-ML and SO-debulked were: Not yet reached, 64, 50 and 49 months, respectively (p = 0.001). CONCLUSIONS: Following PDS, CSR and ≤ 1 cm-SL patients have the best prognosis. In contrast, despite being considered "optimally debulked", ≤1 cm-ML patients have survival similar to those SO-debulked.

Patterns of palliative care referral in ovarian cancer: A single institution 5 year retrospective analysis.

BACKGROUND: The American Society of Clinical Oncology recommends that patients with advanced cancer receive dedicated palliative care services early in their disease course. This investigation serves to understand how palliative care services are utilized for ovarian cancer patients in a tertiary referral center. METHODS: We conducted a retrospective review of women treated for ovarian cancer at our institution from 2010 through 2015. Clinical variables included presence and timing of palliative care referral. Data were correlated utilizing univariable and multivariable parametric and non-parametric testing, and survivals were analyzed using the Kaplan-Meier method and cox-proportional hazard models. RESULTS: We identified 391 women treated for ovarian cancer, of whom 68% were diagnosed with stage III or IV disease. Palliative care referral was utilized in 28% in the outpatient (42%) and inpatient (58%) settings. Earlier use of referral was observed in those who never underwent surgical cytoreduction or had interval cytoreductive surgery (p < 0.001). Palliative care referral was independently associated with advanced stage (OR 1.7, p = 0.02), recurrence (OR 2.0, p = 0.002) and hospice referral (OR 6.0, p < 0.001). In 38% of women referral occurred within 30 days of death, and 17% within one week of death. Outpatient initial consultation was associated with an unadjusted 1 year overall survival benefit (p < 0.01) compared to inpatient consultation. CONCLUSIONS: The outcomes in this study suggest a late use of palliative care that is reactionary to patient needs and not a routine component of ovarian cancer care as national guidelines recommend.

Laparoscopy Compared With Laparotomy for Debulking Ovarian Cancer After Neoadjuvant Chemotherapy.

OBJECTIVE: To compare 3-year survival, length of hospitalization, perioperative mortality, risk of readmission, and residual disease associated with laparoscopic and laparotomic interval debulking surgery among women with epithelial ovarian cancer. METHODS: We used the National Cancer Database to identify a cohort of patients diagnosed with stage IIIC and IV epithelial ovarian cancer between 2010 and 2012 who underwent neoadjuvant chemotherapy and interval debulking surgery. We compared 3-year overall survival, duration of postoperative hospitalization, 90-day postoperative mortality, and residual disease status between women who underwent interval debulking by laparoscopy and by laparotomy. We used the Kaplan-Meier method and Cox regression models in survival analyses. At a significance of .05, this study had 80% power to detect an 8% difference in 3-year survival. The main analysis was intention to treat. RESULTS: We identified 3,071 women meeting inclusion criteria, of whom 450 (15%) underwent surgery initiated laparoscopically. There was no difference in 3-year survival between patients undergoing laparoscopy [47.5%; 95% confidence interval (CI) 41.4-53.5] and laparotomy (52.6%; 95% CI 50.3-55.0; P=.12). Survival did not differ after adjustment for demographic characteristics, facility type, presence of comorbidities, and stage (adjusted hazard ratio, 1.09; 95% CI 0.93-1.28; P=.26). Postoperative hospitalization was slightly shorter in the laparoscopy group (median 4 compared with 5 days, P<.001). Frequency of readmission (5.3% compared with 3.7%; P=.26), death within 90 days of surgery (2.8% compared with 2.9%, P=.93), and suboptimal debulking (20.6% compared with 22.6%, P=.29) did not differ between patients undergoing laparoscopy and laparotomy. CONCLUSION: Ovarian cancer patients selected for laparoscopic interval debulking surgery after neoadjuvant chemotherapy have 3-year survival rates similar to women who undergo interval debulking by laparotomy. Laparoscopy is associated with a modestly shorter postoperative hospitalization, whereas readmission rates and risk of perioperative death are similar for the surgeries.

Phase 1 and 2 study of carboplatin and pralatrexate in patients with recurrent, platinum-sensitive ovarian, fallopian tube, or primary peritoneal cancer.

BACKGROUND: The objective of this phase 1 and 2 trial was to identify the appropriate dose of combined carboplatin and pralatrexate for patients with recurrent, platinum-sensitive ovarian, fallopian tube, and primary peritoneal cancer. METHODS: In phase 1, patients received carboplatin (at an area under the curve of 5) and increasing doses of pralatrexate until the maximum-tolerated dose (MTD) of pralatrexate was achieved. The primary endpoint was the response rate. Additional endpoints were safety, response duration, progression-free survival, overall survival, and pharmacokinetics. RESULTS: Thirty patients were enrolled in phase 1, and 20 were enrolled in phase 2. Of all 50 patients, 49 completed the study. The mean patient age was 59 years, and patients completed a median of 6 cycles. The MTD for pralatrexate was 105 mg/m2 . The clinical benefit rate (complete responses plus partial responses plus stable disease) was 86%. Of 26 patients who received the MTD, 12 had a partial response, 11 had stable disease, and 2 had disease progression. The progression-free survival rate at 3 and 6 months was 87% and 79%, respectively; and the overall survival rate was 98% at 6 and 12 months and 66% at 24 months. Of 30 patients, 18 (60%) in phase 1 experienced an adverse event of any grade; and, of those, 4 patients (13%) had a grade 3 or greater adverse event. In phase 2, 12 patients (60%) had an adverse event of any grade, and 4 (20%) had grade 3 or greater toxicity. There was a significant reduction in the total body clearance of pralatrexate when it was received concurrently with carboplatin. CONCLUSIONS: Most patients responded to carboplatin-pralatrexate combination. This regimen is well tolerated and effective in this patient population.

Patterns of care, predictors and outcomes of chemotherapy for ovarian carcinosarcoma: A National Cancer Database analysis.

OBJECTIVE: The aim of this study is to determine if outcomes of patients with ovarian carcinosarcoma (OCS) differ from those of women with high-grade papillary serous ovarian carcinoma (HG-PSOC) when compared by stage and treatment modalities. METHODS: The National Cancer Database was queried to identify patients with OCS and HG-PSOC diagnosed between 2003 and 2011. Demographic and clinical data were compared, and the impact of tumor histology on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. RESULTS: The final study group consisted of 45,153 women. 2886 (6.39%) had OCS and 42,267 (93.61%) had HG-PSOC. The mean age at diagnosis was 65.43 (±12.21) years for women with OCS and 61.52 (±12.6) years for HG-PSOC (P<0.001). African-American women had higher rate of OCS relative to white non-hispanic women (7.84% vs. 6.37%; P=0.002). Overall, women with OCS had a worse five-year survival rate, 26.63% [95% Confidence Interval (CI)=24.86%-28.53%] vs. 43.61% (95% CI=43.07%-44.17%). This difference persisted for each FIGO disease stage I-IV, with five-year survival consistently worse for women with OCS compared to those with HG-PSOC. Over the entire study period and after adjusting for histology, age, period of diagnosis, SEER registry, marital status, stage, surgery, radiotherapy, and lymph node dissection, carcinosarcoma histology was associated with decreased survival. CONCLUSION: OCS is associated with a poor prognosis compared to HG-PSOC. This difference was noted across all FIGO stages.

Patterns of Care, Predictors, and Outcomes of Adjuvant Therapy for Early- and Advanced-Stage Uterine Clear Cell Carcinoma: A Population-Based Analysis.

OBJECTIVE: The aim of the study was to examine the patterns of care and the impact of chemotherapy and radiation on survival in women diagnosed with uterine clear cell carcinoma (UCCC). The primary outcomes of this analysis were receipt of treatment within 6 months of diagnosis and overall survival. METHODS AND MATERIALS: Women diagnosed with UCCC from 2003 to 2011 were identified through the National Cancer Data Base. Standard univariate and multivariable analyses with logistic regression were performed. Kaplan-Meier survival analysis was used to generate overall survival data. Factors predictive of outcome were evaluated using the log-rank test and Cox proportional hazards model. RESULTS: A total of 3212 patients were identified. Chemotherapy, radiation, and combination chemotherapy and radiation were administered in 23.3%, 19.7%, and 11.1% of women, respectively. After adjusting for age, race, socioeconomic status, facility type, stage, surgery, lymph node dissection, comorbidity index, period of diagnosis, and registry location, there was an association between combined chemotherapy and radiation (hazard ratio, 0.74; 95% confidence interval, 0.61-0.90) with improved survival. Adjuvant therapy was not associated with improved survival among patients with early-stage disease (stages I and II). Both chemotherapy and combined chemotherapy and radiation were associated with significantly improved survival among patients with advanced-stage disease (stages III and IV). CONCLUSIONS: In patients with early-stage UCCC, adjuvant therapy was not associated with significantly improved survival. Chemotherapy and combination of chemotherapy and radiation were associated with improved survival in patients with advanced-stage UCCC.

Mucinous Adenocarcinoma of the Endometrium Compared With Endometrioid Endometrial Cancer: A SEER Analysis.

OBJECTIVE: Mucinous endometrial cancer (MEC) is a rare histologic subtype of endometrial cancers. The purpose of this study is to compare the outcomes of patients with MEC with patients with endometrioid endometrial cancers (EEC), and to determine whether there are significant clinicopathologic differences between these tumors. METHODS: Surveillance, Epidemiology, and End Results (SEER) Program data for 1988 to 2009 was reviewed. Demographic and clinical data were compared. The impact of histology on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. RESULTS: The study group consisted of 104,659 women, 103,097 (98.5%) had EEC and 1562 (1.5%) MEC. The mean age at diagnosis for EEC and MEC was 62 and 63.4, respectively (P<0.001). MEC tumors were more frequently classified as grade 1 (51.3% vs. 44%; P<0.001). In patients with MEC, a higher rate of pelvic lymph node metastasis (16.3% vs. 10.4%; P<0.001) was noted, but not para-aortic lymph node metastasis (5.1% vs. 4%; P=0.1). After adjusting for race, period of diagnosis, SEER registry, marital status, stage, age, surgery, radiotherapy, grade, histology, and lymph node dissection, there was no difference in survival between MEC and EEC (hazard ratio 0.90; 95% confidence interval, 0.78-1.05). CONCLUSIONS: Mucinous histology does not significantly affect survival when compared with endometrioid histology in endometrial cancer. Patients with MEC were more likely to have positive pelvic lymph nodes at the time of surgery.

Intraoperative Radiation Therapy in the Management of Gynecologic Malignancies.

OBJECTIVE: The aim of this study was to review the experience with intraoperative radiation therapy (IORT) in the treatment of gynecologic cancers at the Massachusetts General Hospital. METHODS: From January 1, 1994 to December 31, 2011, 32 patients were treated with IORT at Massachusetts General Hospital. Hospital, pathology, and office medical records and radiation oncology records were reviewed. The Kaplan-Meier method was used to generate disease-free survival and overall survival (OS) data. RESULTS: In 27 patients (84.4), surgical resection margins were microscopically positive. In 5 patients (15.6%), margins were grossly positive. For patients with microscopic disease, 5-year disease-free survival was 40.9% (57 mo), compared with 9.1% (23 mo) for those with gross residual disease (P=0.001). Five-year OS was also statistically improved for patients with microscopic residual disease, when compared with OS among patients with gross residual disease, 77.3% (93 mo) and 54.5% (40 mo), respectively (P=0.001). The risk of distant metastases in patients with gross residual disease was 87%, compared with 28% in patients with microscopic disease (P=0.02). CONCLUSIONS: Volume of residual disease before IORT is an important prognostic indicator. Local recurrence and distant metastases were more common among patients with gross residual disease left in situ at time of IORT. Our institutional experience with IORT further supports the importance of complete surgical resection.

Changing Trends in Lymphadenectomy for Endometrioid Adenocarcinoma of the Endometrium.

OBJECTIVE: To describe trends in the use of lymphadenectomy for endometrioid adenocarcinoma of the endometrium between 1998 and 2012. METHODS: A time-trend analysis was conducted using a population-based cancer registry covering 28% of the population of the United States. To quantify differences over the study period time, the frequency of lymphadenectomy and nodal metastasis among women who underwent surgical treatment of endometrioid endometrial adenocarcinoma was compared among consecutive 3- to 4-year periods. Biannual frequency of lymphadenectomy was modeled with Joinpoint regression to identify when potential changes in trends occurred and calculate annual percentage change. RESULTS: A total of 74,365 women who underwent surgery between 1998 and 2012 were analyzed. Frequency of lymphadenectomy increased by 4.2% annually (95% confidence interval [CI] 3.7-4.6) from 1998 to 2007, after which the frequency declined by 1.6% per year (95% CI 0.9-2.2). Between 1998-2000 and 2007-2009, the frequency of lymphadenectomy rose from 48.7% to 65.5% (risk difference 16.8%, 95% CI 15.4-18.1), the proportion of women found to have nodal metastasis increased by 1.1% (95% CI 0.4-1.7), and the frequency of negative lymphadenectomy increased by 15.7% (95% CI 14.3-17.1). The decline in frequency of lymphadenectomy after 2007 was associated a 3.1% (95% CI 2.1-4.1) decline in the rate of negative lymphadenectomy, but no change in the proportion of women found to have nodal metastasis (P=.17). CONCLUSION: The frequency of lymphadenectomy in the surgical treatment of endometrioid endometrial cancer increased by 4.2% annually from 1998 to 2007 and decreased by 1.6% annually from 2007 to 2012.

Effect of Educational Intervention on Cervical Cancer Prevention and Screening in Hispanic Women.

To evaluate the effect of an educational intervention on four domains of health care utilization and cervical cancer prevention and screening in a Hispanic population. Data collected from a survey were used to design education strategies focused on four domains of interest. A second survey was conducted to measure the impact of the intervention. Following the intervention, respondents were more likely to have any knowledge of human papillomavirus (HPV). Respondents living in the United States (US) for <5 years were more likely to have had a Papanicolaou smear in the preceding 3 years (p = 0.0314), to report knowledge of HPV vaccination (p = 0.0258), and to be willing to vaccinate themselves (p = 0.0124) and their children (p = 0.0341) after the intervention. Educational interventions designed to meet the needs identified by the sample group led to an increase in HPV awareness throughout the entire population surveyed and an increase in health care service utilization and HPV vaccine acceptance for women living in the US for <5 years. These tools should be promoted to reduce the cervical cancer burden on vulnerable populations.

Incidence and effects on mortality of venous thromboembolism in elderly women with endometrial cancer.

OBJECTIVE: To describe the incidence of thromboembolic events (venous thromboembolism) before and after the diagnosis of epithelial endometrial cancer and to evaluate the effects of these events on survival. METHODS: We used the National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registries linked to Medicare claim files to identify patients with epithelial endometrial cancer diagnosed between 1992 and 2009. To identify venous thromboembolism events 3 months before diagnosis and up to 24 months after diagnosis, we used International Classification of Diseases, 9th Revision, and Healthcare Common Procedure Coding System codes. RESULTS: A total of 23,122 patients were included; of them 1,873 (8.1%) developed a venous thromboembolism. Patients with low-grade (grades 1 and 2) endometrioid adenocarcinoma had a significantly lower rate of venous thromboembolism 3 months before and 6 months after the diagnosis of cancer (3.6%; 95% confidence interval [CI] 3.3-3.9%) compared with carcinosarcoma (9.2%; 95% CI 7.8-10.8%), clear cell (6.9%; 95% CI 4.8-9.7%), uterine serous cancer (8.1%; 95% CI 7.01-9.3%), and grade 3 endometrioid adenocarcinoma (6.1%; 95% CI 5.4-6.9%) (P<.001). On multivariate analysis during the same time period, most recent time periods of diagnosis, carcinosarcoma histology compared with lower grade endometrial cancer, higher stage, African American race, marital status, chemotherapy delivery, and lymph node dissection were associated with increased risk of venous thromboembolism. The median overall survival for women who experienced a venous thromboembolism 3 months before the diagnosis of endometrial cancer was 31 months (95% CI 20-48 months); in women diagnosed with venous thromboembolism 6 months after the cancer diagnosis was 37 months (95% CI 31-44), and in women who did not experienced a venous thromboembolism was 111 months (95% CI 109-114). After adjusting for prognostic factors, there was an association between venous thromboembolism diagnosed 3 months before endometrial cancer (hazard ratio 1.69, 95% CI 1.34-2.13) or 6 months after the diagnosis (hazard ratio 1.57, 95% CI 1.44-1.71) and lower survival. CONCLUSION: Patients with uterine serous cancer, carcinosarcoma, clear cell carcinoma, and grade 3 endometrioid adenocarcinoma had a higher rate of venous thromboembolism than patients with low-grade endometrioid adenocarcinoma. A diagnosis of venous thromboembolism was associated with decreased survival in elderly patients with endometrial cancer. LEVEL OF EVIDENCE: II.
