RESUMEN

BACKGROUND: The impact of blood transfusion on ovarian cancer survival is uncertain. OBJECTIVE: To investigate whether peri-operative blood transfusion negatively impacted progression-free survival, overall survival, and quality of life in patients with advanced ovarian cancer. METHODS: We performed an ancillary analysis of the European Organization for Research and Treatment (EORTC) 55971 phase III trial, in which patients were randomized to primary debulking surgery versus neoadjuvant chemotherapy. Patients included in the per-protocol analysis were categorized by receipt of a transfusion. RESULTS: 612 of 632 (97%) of patients had adequate data for analysis. Of those, 323 (53%) received a transfusion. The transfusion cohort was more likely to have had better Word Health Organization (WHO) performance status, serous histology, undergone primary debulking surgery, and received more aggressive surgery, with higher rates of no gross residual disease. Median overall survival was 34.0 vs 35.2 months in the no transfusion and transfusion cohorts (p=0.97). The adjusted HR for death was 1.18 (95% CI 0.94 to 1.48) in favor of the transfusion cohort. Median progression-free survival was 13.6 vs 12.6 months in the no transfusion and transfusion cohorts (p=0.96). The adjusted HR for progression was 1.14 (95% CI 0.91 to 1.43). There were no significant differences in global quality of life, fatigue, dyspnea, or physical functioning between the two cohorts at baseline or at any of the four assessment times. Grade 3 and 4 surgical site infections were more common in the transfusion cohort. CONCLUSION: Transfusion did not negatively impact progression-free survival or overall survival; however, it was associated with increased peri-operative morbidity without improvements in quality of life.

RESUMEN

Straight line scoring (SLS), defined as trainee assessments with the same score for all evaluation items, is statistically improbable and potentially indicates inaccurate assessment. Factors contributing to higher SLS rates are unknown, and knowledge of SLS prevalence within oncologic training is lacking. SLS frequency was measured for evaluations from all Accreditation Council for Graduate Medical Education (ACGME)-accredited programs at a single cancer care institution between 2014 and 2018. SLS prevalence was estimated using hierarchical linear models (HLM) that considered characteristics of evaluator, trainee, and evaluation potentially related to SLS. Results were compared with national SLS rates. Six thousand one hundred sixty evaluations were included from 476 evaluators. Overall prevalence of SLS was 12.1% (95% CI 4.5-28.8). Residents (vs fellows) were less likely to have SLS evaluations (OR 0.5, 95% CI 0.4-0.8), though for all trainees increasing training year corresponded with increasing SLS frequency (OR 1.5, 95% CI 1.3-1.7). SLS was more common in procedural specialties compared with medical specialties (OR 2.1, 95% CI 1.1-3.8). Formative evaluations had lower SLS rates (OR 0.6, 95% CI 0.5-0.9) than summative evaluations, while milestone-based evaluations had higher rates than those that were not milestone-based (OR 1.5, 95% CI 1.03-2.2). Features of evaluators, such as subspecialty within oncology, and of trainees, such as seniority or trainee type, were related to SLS. Summative intent and milestone-based evaluations were more likely to be straight line scored. Specific evaluation scenarios at higher risk of SLS should be further examined.

RESUMEN

PURPOSE: To evaluate the effect of dasatinib therapy on EphA2 signaling in cancers of women with measurable (biopsy amenable) advanced-stage, chemo-naïve primary or recurrent endometrial cancer. Preliminary efficacy was also assessed. PATIENTS AND METHODS: We performed a pilot study of single-agent dasatinib lead-in, followed by triplet dasatinib, paclitaxel, and carboplatin. We measured the downstream effectors of EphA2 signaling in pre- and post-dasatinib treatment biopsy tissue samples; we also determined the severity of adverse events and patients' progression-free survival and overall survival durations. RESULTS: Eighteen patients were recruited and given dasatinib (150 mg orally daily for 14 days), followed by paclitaxel, carboplatin and dasatinib (daily) for six cycles (21-day cycles). Seventeen patients were evaluable for toxicity and 11 patients for response. A reverse phase protein array and proximity ligation assay revealed that CRAF/BRAF dimerization, caveolin-1 level, and Notch pathway signaling were predictive of response and resistance to dasatinib. Overall, the objective response rate was 45% (95% CI: 17%-77%), with median progression-free survival duration of 10.5 months and median overall survival duration of 30.4 months. The most common grade 3 or 4 adverse events were neutropenia (76%), thrombocytopenia (53%), anemia (53%), and fatigue (12%). CONCLUSIONS: Caveolin-1 expression, in combination with CRAF/BRAF heterodimerization, is associated with resistance to EphA2 targeting by dasatinib. The triplet combination showed interesting clinical activity in endometrial cancer with acceptable toxicity. Pretreatment with dasatinib may accentuate combination therapy toxicity.

RESUMEN

BACKGROUND: The incidence of complex atypical hyperplasia and early-stage endometrioid endometrial cancer is increasing, in part owing to the epidemic of obesity, which is a risk factor tightly linked to the development of endometrial hyperplasia and cancer. The standard upfront treatment for complex atypical hyperplasia and early-stage endometrial cancer is hysterectomy. However, nonsurgical treatment of early-stage endometrial neoplasia may be necessary owing to medical comorbidities precluding surgery or desired future fertility. OBJECTIVE: This study aimed to evaluate the efficacy of the levonorgestrel intrauterine device to treat complex atypical hyperplasia and grade 1 endometrioid endometrial carcinoma. STUDY DESIGN: A single-institution, single-arm, phase II study of the levonorgestrel intrauterine device (52 mg levonorgestrel, Mirena) was conducted in patients with complex atypical hyperplasia or grade 1 endometrioid endometrial cancer. The primary endpoint was pathologic response rate at 12 months, including complete or partial response. Quality of life and toxicity were assessed. Molecular analyses for proliferation markers, hormone-regulated genes, and wingless-related integration site pathway activation were performed at baseline and 3 months. RESULTS: A total of 57 patients were treated (21 endometrial cancer, 36 complex atypical hyperplasia). The median age was 48.0 years, and the median body mass index was 45.5 kg/m2. Of the 47 evaluable patients, 12-month response rate was 83% (90% credible interval, 72.7-90.3)-37 were complete responders (8 endometrial cancer; 29 complex atypical hyperplasia), 2 were partial responders (2 endometrial cancer), 3 had stable disease (2 endometrial cancer; 1 complex atypical hyperplasia), and 5 had progressive disease (3 endometrial cancer; 2 complex atypical hyperplasia). After stratification for histology, the response rate was 90.6% for complex atypical hyperplasia and 66.7% for grade 1 endometrioid endometrial cancer. Notably, 4 patients (9.5%) experienced relapse after the initial response. Adverse events were mild, primarily irregular bleeding and cramping. Quality of life was not negatively affected. At 3 months, exogenous progesterone effect was present in 96.9% of responders (31 of 32) vs 25% of nonresponders (2 of 8) (P=.001). Nonresponders had higher baseline proliferation (Ki67) and lower dickkopf homolog 3 gene expression than responders (P=.023 and P=.030). Nonresponders had significantly different changes in secreted frizzled-related protein 1, frizzled class receptor 8, and retinaldehyde dehydrogenase 2 compared with responders. CONCLUSION: The levonorgestrel intrauterine device has a substantial activity in complex atypical hyperplasia and grade 1 endometrioid endometrial cancer, with a modest proportion demonstrating upfront progesterone resistance. Potential biomarkers were identified that may correlate with resistance to therapy; further exploration is warranted.

RESUMEN

INTRODUCTION: The surgical approach for interval debulking surgery after neoadjuvant chemotherapy has been extrapolated from primary tumor reductive surgery for high-grade ovarian cancer. The study objective was to compare pathologic distribution of malignancy at interval debulking surgery versus primary tumor reductive surgery. METHODS: Patients with a diagnosis of high-grade serous or mixed, non-mucinous, epithelial ovarian, fallopian tube or primary peritoneal cancer who underwent neoadjuvant chemotherapy or primary tumor reductive surgery and had at least 6 months of follow-up were identified through tumor registry at a single institution from January 1995 to April 2016. Pathologic involvement of organs was categorized as macroscopic, microscopic, or no tumor. Statistical analyses included Mann-Whitney and Fisher's exact tests. RESULTS: Of 918 patients identified, 366 (39.9%) patients underwent interval debulking surgery and 552 (60.1%) patients underwent primary tumor reductive surgery. Median age was 62.3 years (range 25.3-92.5). The majority of patients in the interval debulking surgery group were unstaged (261, 71.5%). In the patients who had a primary tumor reductive surgery, 406 (74.6%) had stage III disease. In both groups, the majority of patients had serous histology: 325 (90%) and 435 (78.8%) in the interval debulking and primary tumor reductive surgery groups, respectively. There was a statistically significant difference between disease distribution on the uterus between the groups; 31.4% of the patients undergoing interval debulking surgery had no evidence of uterine disease compared with 22.1% of primary tumor reductive surgery specimens (p<0.001). In the adnexa, there was macroscopic disease present in 253 (69.2%) and 482 (87.4%) of cases in the interval vs primary surgery groups, respectively (p<0.001). Within the omentum, no tumor was present in the omentum in 52 (14.2%) in the interval surgery group versus 91 (16.5%) in the primary surgery group (p<0.001). In the interval surgery group, there was no tumor involving the small and large bowel in 49 (13.4%) and 28 (7.7%) pathologic specimens, respectively. This was statistically significantly different from the small and large bowel in the primary surgery group, of which there was no tumor in 20 (3.6%, p<0.001) and 16 (2.9%, p<0.001) of cases, respectively. CONCLUSION: In patients undergoing interval debulking surgery, there was less macroscopic involvement of tumor in the uterus, adnexa and bowel compared with patients undergoing primary cytoreductive surgery.

RESUMEN

BACKGROUND: Although there are a growing number of survivors of adolescent and young adult (AYA) cancer, to the authors' knowledge the long-term overall survival (OS) patterns for AYA cancer survivors are underreported. The objective of the current study was to assess the long-term survival of AYA cancer survivors and identify factors associated with diminished long-term survival. METHODS: The authors used The University of Texas MD Anderson Cancer Center's tumor registry to identify 5-year survivors of cancer diagnosed as AYAs (ages 15-39 years) between the years 1970 and 2005, and who were alive 5 years after diagnosis. Kaplan-Meier curves were used to estimate OS rates over time, and Cox proportional hazards models were fitted to evaluate the association of covariates with OS. RESULTS: The authors identified 16,728 individuals who were 5-year survivors of cancer and were diagnosed as AYAs with a median follow-up of 20.0 years. The 10-year, 20-year, and 25-year OS rates were 86% (95% confidence interval [95% CI], 85%-86%), 74% (95% CI, 73%-75%), and 68% (95% CI, 67%-68%), respectively, all of which were lower than the age-adjusted estimated survival rates of the general population. Long-term OS improved for AYAs diagnosed between 2000 and 2005 compared with those diagnosed in the prior decades (P < .001). Older age at the time of diagnosis, receipt of radiation, and diagnoses including central nervous system tumors and breast cancer each were associated with diminished long-term survival. CONCLUSIONS: AYA cancer survivors have inferior long-term survival compared with the general population. Studies investigating the prevalence and types of late treatment effects and causes of death among AYA survivors are needed to more accurately identify AYAs who are at highest risk of early or late mortality.

RESUMEN

INTRODUCTION: 50-70% of epithelial ovarian cancers overexpress epidermal growth factor receptor, and its expression has been correlated with poor prognosis. We conducted a phase Ib/II trial to examine the efficacy, safety, and toxicity of gefitinib, a tyrosine kinase inhibitor, combined with topotecan in women with recurrent ovarian cancer with epidermal growth factor receptor positivity. METHODS: Patients with measurable recurrent or persistent cancer after treatment with a platinum containing regimen with positive epidermal growth factor receptor expression, as determined by immunohistochemistry, were eligible for the study. Initial treatment was 250 mg/day gefitinib (oral) and 2.0 mg/m2 topotecan (intravenous) on days 1, 8, and 15, on a 28 day cycle. Dose escalations were planned for topotecan (dose levels 1-3: 2, 3, and 4 mg/m2) until the maximum tolerated dose was reached. RESULTS: 19 patients received a total of 61 cycles. Median age was 59.8 years (range 42-76 years). Histologic types in treated patients included 74% serous (n=14), 11% mixed (n=2), 11% transitional (n=2), and 5% clear cell (n=1). For phase Ib, three patients were treated at dose level 1, three at dose level 2, and three at dose level 3 for topotecan. The maximum tolerated dose was 4.0 mg/m2 (days 1, 8, and 15) for topotecan and 250 mg (daily) for gefitinib. Therefore, dose level 3 was used for phase II. Among the 19 patients, 63.2% (n=12) had progressive disease, 15.8% (n=3) had stable disease, 10.5% (n=2) had a partial response, and 10.5% (n=2) were not evaluable. The most serious adverse events of any grade attributed to the therapy were anemia (89.4%), neutropenia (68.4%), abdominal pain (84%), constipation (78.9%), and diarrhea (78.9%). CONCLUSION: Although the drug combination was relatively well tolerated, this prospective phase Ib/II clinical trial did not show sufficient clinical activity of topotecan combined with gefitinib in patients with epidermal growth factor receptor positive recurrent ovarian, fallopian tube, or peritoneal cancers.

RESUMEN

OBJECTIVE: To describe disparities in patterns of hospice use and end-of-life costs among ovarian cancer patients. METHODS: Using Texas Cancer Registry-Medicare data, ovarian cancer patients deceased 2005-2012 with >12 months of continuous Medicare coverage before death were included. Descriptive statistics and multivariable logistic regressions were used to evaluate patterns of hospice use. Cost and resource utilization was obtained from Medicare claims and analyzed using a non-parametric Mann-Whitney test. RESULTS: 2331 patients were assessed: 1788 (77%) white, 359 (15%) Hispanic, 158 (7%) black and 26 (1%) other. 1756 (75%) enrolled in hospice prior to death but only 1580 (68%) died with hospice. 176 (10%) of 1756 patients unenrolled and died without hospice. 346 (20%) unenrolled from hospice multiple times. From 2008 to 2012, patients were less likely to unenroll from hospice prior to death. Black patients were more likely to unenroll from hospice prior to death (OR 2.07 [1.15-3.73]; p = 0.02) compared to white patients. The median amount paid by Medicare during the last six months of life was $38,530 for those in hospice compared to $49,942 if never enrolled in hospice (p < 0.0001) and was higher for black and Hispanic patients compared to white patients. 30% hospice unenrolled patients and 40% multiply enrolled hospice patients received at least one life extending or invasive care procedure following unenrollment from hospice. CONCLUSION: Recently, more patients remain enrolled in hospice, but black patients have a higher risk of unenrollment. Hospice enrollment was associated with lower costs as long as a patient did not unenroll from hospice.

RESUMEN

OBJECTIVE: We assessed preferences for cancer risk management strategies for Lynch syndrome (LS) in LS-affected women. METHODS: Women with LS aged ≥25 years evaluated 9 cancer risk management strategies using a visual analog scale (VAS) and modified standard gamble (SG). For the VAS, women ranked each strategy ranging from 0 (least preferred) to 100 (most preferred). VAS scores were calculated by dividing the corresponding number by 100. Scores closer to 1.0 reflected more favorable strategies. For the SG, participants were asked to specify their expected threshold of lifetime risk of endometrial or colorectal cancer, ranging from 0 to 100%, at which they would consider undertaking each strategy. Strategies included chemoprevention, cancer screening, and preventive surgery. Cancer worry and perceived cancer risk measures were collected on a subset of participants. RESULTS: Sixty-one women completed preference assessments. By VAS, annual combined screening was the most preferred, followed by annual screenings and chemoprevention with oral contraceptives. By SG, women were the most willing to endorse oral contraceptives and biannual screening strategies at the lowest threshold of lifetime risk followed by annual screening strategies. Surgical interventions were the least preferred strategies using both VAS and SG. Women with a family history of gynecologic or colorectal cancer were less likely to consider prevention or screening options compared to women without a family history. Cancer worry was higher among women with a positive family history of LS cancer. CONCLUSION: Understanding women's preferences may facilitate optimal use and adherence to cancer risk management strategies.

RESUMEN

OBJECTIVE: To evaluate the efficacy and economic impact of a transfusion reduction initiative for patients undergoing gynecologic surgery. METHODS: We conducted a prospective healthcare improvement study to align transfusion practices with the American Society of Hematology's Choosing Wisely® campaign. Baseline transfusion rates were determined retrospectively for all major gynecologic surgical cases from 3/1/14 to 6/30/14. Data for the post-intervention period from 5/15/15 to 5/16/16 were captured prospectively. The primary outcome was transfusion within 72 h of surgery. Secondary outcomes included perioperative morbidity, mortality, number of units ordered per transfusion episode and cost. RESULTS: We identified 1281 surgical cases, 334 in the baseline and 947 in the post-implementation cohort. The baseline cohort was noted to have a higher median estimated blood loss (100 v. 75 mL, P < 0.01). Otherwise, there were no differences in clinical or perioperative characteristics between the two cohorts. The perioperative transfusion rate decreased from 24% to 11% (adjusted OR 0.27, 95% CI 0.16 to 0.45; P < 0.001). The perioperative laparotomy transfusion rate decreased from 48% to 23% (adjusted OR 0.21, 95% CI 0.12, 0.37; P < 0.001). The number of occurrences in which more than one unit of blood was ordered at a time decreased from 65% to 23%, P < 0.001. The incidence of surgical site infections declined in the post-intervention group, otherwise there were no differences in 30-day mortality, cardiac, venous thromboembolism or readmission rates between the groups. The projected cost savings was $161,112 over the 12-month intervention period. CONCLUSIONS: Implementation of an educational based transfusion reduction program was associated with substantial reductions in perioperative transfusions and cost without significant changes in morbidity or mortality.

RESUMEN

BACKGROUND: Physician assistants (PAs) often have been embedded in academic medical centers to help ensure an adequate patient care workforce while supporting compliance with work-hour restrictions for residents and fellows (also called trainees). Limited studies have explored the effect of PAs on trainee learning. This qualitative study explored, from the perspective of physician faculty and PAs, how PAs working in the clinical learning environment can enhance or hinder trainee learning. METHODS: Using purposive sampling, 12 PAs and 12 physician faculty members in one US teaching hospital were selected for semistructured interviews. Data collection and analysis were characterized by an iterative process. Data analysis was informed by principles of conventional content analysis. RESULTS: Participants identified various ways in which PAs may affect trainee learning, intrinsically linked to the roles PAs assume in the clinical learning environment: clinician, teammate, and clinical teacher. Trainee learning may be enhanced because learning time can be optimized by having PAs in the clinical learning environment. Trainees can learn about PAs and how to collaborate with them, and PAs can enculturate and provide clinical instruction to trainees. Trainee learning may be hindered if learning opportunities for trainees go to PAs, trainees feel intimidated by experienced PAs, or trainees become too dependent on PAs. CONCLUSIONS: Our findings demonstrate enhancements and hindrances to trainees' learning linked to three key roles PAs perform in the clinical learning environment. These findings can inform how PAs are integrated into teaching services. Further investigation is needed to understand how PAs can balance their professional roles to foster effective collaborative practice and learning.

RESUMEN

BACKGROUND: With ongoing healthcare reform and shrinking numbers of oncologists, appropriate triaging of gynecologic cancer survivor care is crucial. Input from patients is a necessary part of this task. The objective of this study was to assess the preferences of gynecologic cancer survivors for surveillance after the completion of treatment. METHODS: A 38-item questionnaire was developed and launched in conjunction with the Foundation for Women's Cancer (FWC). All women who registered as gynecologic cancer survivors with the FWC were invited to participate. Patients were asked about physician preferences for multiple symptoms and diagnoses, and when they felt comfortable transferring care out of their oncologists' offices. Analyses were performed with chi-square and logistic regression. RESULTS: Six hundred twenty four patients completed the questionnaire. Sixty six percent had ovarian cancer, and 86% were primarily treated by a gynecologic oncologist. Fifty seven percent of the respondents reported being unwilling to see a physician other than their oncologist for survivorship care at any time. Women age > 60 years were less willing to leave their oncologists for survivorship care at any time compared to younger women (OR 1.53 [95% CI 1.03-2.27], p = 0.03). Ovarian cancer survivors were also more likely to report a desire to stay with their oncologists compared with uterine cancer survivors (p < 0.001). With few exceptions, respondents preferred management of non-oncologic medical problems by their oncologists. CONCLUSIONS: Gynecologic cancer survivors prefer that their oncologists remain heavily involved in survivorship care. Reconciling patient needs with physician and financial constraints will be a challenge as the survivor population continues to grow.

RESUMEN

OBJECTIVE: Pelvic exenteration (PE) is a surgical procedure associated with significant morbidity offered to select women with locally advanced or recurrent gynecologic cancers. This ongoing study examines an array of patient-reported outcomes and satisfaction with PE. METHODS: Since February 2009, prospectively enrolled participants completed questionnaires evaluating body image (BIS), depression (CESD), social support (DUFSS), symptoms (MDASI), sexual function (SAQ), functional status (SF-12), quality of life (The Stoma-QOL), satisfaction with decision (SWD) and an investigator-designed survey at baseline, 6, and 12months after PE. Mann-Whitney and Wilcoxon signed-rank tests were used to evaluate the data. RESULTS: Fifty-four women enrolled. Median age was 56years (31, 85). Median BMI was 30.7kg/m2 (16.8, 54.4). The majority of patients (78%) were white. Cancer diagnoses included 41% cervix, 22% uterus, 19% vagina, 17% vulva and 2% ovary. Most surgeries were total PEs (76%). Patients were satisfied with their decision to undergo PE at 6 and 12months. One year after exenteration, 79% of women stated they would have a PE again. Sexual pleasure decreased from baseline to 12months after PE (p=0.02), while sexual discomfort remained unchanged (p=0.42). Body image worsened over time (p=0.003). Physical functioning (SF-12) declined (p=0.001), while mental functioning remained stable (p=0.46). There were no significant changes in stoma-related QOL, social support, or depression scores. CONCLUSIONS: Despite a decrease in physical functioning, persistent low body image and sexual pleasure, most women were satisfied with their decision and would undergo pelvic exenteration again. This study identifies survivorship issues that should be addressed after PE.

RESUMEN

PURPOSE: To determine the relationship between chemotherapy dose modification (dose adjustment or treatment delay), overall survival (OS) and progression-free survival (PFS) for women with advanced-stage epithelial ovarian carcinoma (EOC) and primary peritoneal carcinoma (PPC) who receive carboplatin and paclitaxel. METHODS: Women with stages III and IV EOC and PPC treated on the Gynecologic Oncology Group phase III trial, protocol 182, who completed eight cycles of carboplatin with paclitaxel were evaluated in this study. The patients were grouped per dose modification and use of granulocyte colony stimulating factor (G-CSF). The primary end point was OS; Hazard ratios (HR) for PFS and OS were calculated for patients who completed eight cycles of chemotherapy. Patients without dose modification were the referent group. All statistical analyses were performed using the R programming language and environment. RESULTS: A total of 738 patients were included in this study; 229 (31%) required dose modification, 509 did not. The two groups were well-balanced for demographic and prognostic factors. The adjusted hazard ratios (HR) for disease progression and death among dose-modified patients were: 1.43 (95% CI, 1.19-1.72, P < 0.001) and 1.26 (95% CI, 1.04-1.54, P = 0.021), respectively. Use of G-CSF was more frequent in dose-modified patients with an odds ratio (OR) of 3.63 (95% CI: 2.51-5.26, P < 0.001) compared to dose-unmodified patients. CONCLUSION: Dose-modified patients were at a higher risk of disease progression and death. The need for chemotherapy dose modification may identify patients at greater risk for adverse outcomes in advanced stage EOC and PPC.

RESUMEN

BACKGROUND: Surgical site infections (SSIs) lead to increased patient morbidity and healthcare costs. Our objective was to decrease the SSI rate following gynecologic surgery. METHODS: Adult patients undergoing abdominal surgery for gynecologic malignancy or benign disease received the following: patient education; preoperative antibacterial soap; appropriate antibiotic prophylaxis; change of gloves and use of clean instruments at surgical closure; surgical dressing for 48 h; and a post-discharge phone call. The baseline SSI rate was determined retrospectively (1 April 2014-30 June 2014), while the post-intervention SSI rate was determined prospectively (16 February 2015-15 October 2015). The main outcome was the overall SSI rate with secondary outcomes, including the rate of superficial, deep, incisional and organ space infection, as well as the cost effectiveness of the bundle. RESULTS: A total of 232 baseline and 555 post-intervention patients were included in the study. No differences were observed between the baseline and post-intervention groups with regard to median body mass index (BMI), surgical approach, receipt of preoperative chemotherapy and/or radiation therapy, and cases including bowel surgery. Overall, the SSI rate decreased significantly from baseline [12.5 %] to post-intervention [7.4 %] (odds ratio [OR] 0.56, 90 % confidence interval [CI] 0.37-0.85; p = 0.01). A 40 % decrease was noted in the rate of superficial and deep infections (9.5 vs. 5.9 %; OR 0.60, 90 % CI 0.38-0.97; p = 0.04) and SSIs after open surgery (21.4 vs. 13.2 %; OR 0.56, 90 % CI 0.34-0.92; p = 0.03). The estimated cost of the intervention was $19.26/case and the net total amount saved during the post-intervention period was $65,625 month. CONCLUSIONS: This bundled intervention led to a significant decrease in the overall SSI rate and was cost effective. The largest decreases in SSIs were in incisional infections and following open surgery.

RESUMEN

OBJECTIVES: We compared the diagnostic accuracy of 4 depression screening scales, using traditional and alternative scoring methods, to the gold standard Structured Clinical Interview-DSM IV major depressive episode (MDE) in ovarian cancer patients on active treatment. METHODS: At the beginning of a new chemotherapy regimen, ovarian cancer patients completed the following surveys on the same day: the Center for Epidemiological Studies Depression Scale (CES-D), the Beck Depression Inventory Fast-Screen for Primary Care (BDI-FastScreen), the Patient Health Questionnaire-9 (PHQ-9), and a 1-item screener ("Are you depressed?"). Each instrument's sensitivity, specificity, positive predictive value (PPV) and negative predictive value were calculated with respect to major depression. To control for antidepressant use, the analyses were re-run for a subsample of patients who were not on antidepressants. RESULTS: One hundred fifty-three ovarian cancer patients were enrolled into the study. Only fourteen participants met SCID criteria for current MDE (9%). When evaluating all patients regardless of whether they were already being treated with antidepressants, the two-phase scoring approach with an alternate cutpoint of 6 on the PHQ-9 had the best positive predictive value (PPV=32%). Using a traditional cutpoint of 16 on the CES-D resulted in the lowest PPV (5%); using a more stringent cutpoint of 22 resulted in a slightly improved but still poor PPV, 7%. CONCLUSIONS: Screening with a two-phase PHQ-9 proved best overall, and its accuracy was improved when used with patients who were not already being treated with antidepressants.

RESUMEN

OBJECTIVES: This study aims to examine practice patterns of gynecologic oncologists (GO) regarding fertility-sparing treatments (FST) for gynecology malignancies and explores attitudes toward collaboration with reproductive endocrinologists (RE). METHODS: An anonymous 23-question survey was sent to 1087 GO with a 14.0% completion rate. Descriptive statistics, Fisher's exact test, and Chi-square tests were used for data analysis. RESULTS: The majority of GOs offer FST for gynecologic malignancies. Providers seeing larger numbers of reproductive age women were more likely to consider cancer prognosis (p<0.03) and cancer stage (p<0.01) as key factors. Providers in the Midwestern US considered socioeconomic status more often when offering FST than those in the South (p<0.04). Those practicing in urban settings were more likely to feel that collaborating with a RE prior to treatment could improve treatment planning for women considering FST (p<0.02). Finally, providers in urban or suburban areas more often felt collaboration with a RE improves pregnancy outcomes in women who pursue FST (p<0.01, p<0.02) compared to rural practitioners. CONCLUSIONS: While FST offers women the chance to pursue pregnancy after cancer, there are minimal data on factors that influence whether FST is offered and if collaboration with a RE is sought in the management of these patients. The number of reproductive age women seen, geographic location, and practice setting are important variables that may influence current practice. Understanding these factors can help identify opportunities to improve oncologic and reproductive outcomes of this patient population.

RESUMEN

PURPOSE: The purpose of this study is to evaluate if locus of control (LOC) predicts various quality of life (QOL) and mental well-being measures among terminally ill cancer patients at the time of palliative care consult. METHODS: Multi-site analysis of patients with advanced cancer being seen as new patients in a Palliative and Supportive Care outpatient clinic. Patients completed the following surveys: locus of control (LOC) scale, Functional Assessment of Chronic Illness Therapy-General (FACT-G), Functional Assessment of Chronic Illness Therapy-Spiritual (FACIT-Sp), Hospital Anxiety Depression Scale (HADS), and Herth Hope Index (HHI). Regression models were created to examine the effect of LOC upon QOL, symptoms, and other measures of mental well-being. These models adjusted for the effect of age, gender, race, partnership status, education, and months since diagnosis as potential confounders. RESULTS: This study enrolled 100 patients. After adjusting for site, race, and partnership status, higher levels of LOC chance predicted decreased QOL (FACT-G) (p < 0.01). Higher levels of LOC chance also correlated with increased depression and anxiety (p ≤ 0.01) and decreased meaning/peace and faith (p ≤ 0.01). Additionally, higher levels of LOC chance predicted decreased hope (HHI) (p ≤ 0.001). CONCLUSIONS: Terminally ill cancer patients with a high LOC chance may be at risk for decreased physical and mental well-being at the end of life. Efforts should be made to identify these patients and design interventions to increase their feeling of control over the situation in order to improve physical and mental well-being at the end of life.

RESUMEN

OBJECTIVE: The objective of this article was to develop and validate a scale that assesses the readiness of gynecologic oncology patients to engage in advance care planning. METHODS: The Advance Care Planning Readiness Scale (ACPRS) was validated across 3 independent samples of gynecologic oncology patients. In step I, patients underwent cognitive interviewing to determine if the scale items were comprehensible and applicable to patients. Based on this, modifications to the scale (addition, removal, and merger of items) were completed. In step II, the revised scale was administered to a new sample of patients to assess scale reliability and validity. An exploratory factor analysis determined if the scale loaded onto unique factors. In step III, the revised scale was administered to a third sample of patients, and a confirmatory factor analysis was conducted to test the factor structure proposed in step II. Associations between ACPRS score and completion of advance directives were evaluated. RESULTS: Based on patients' responses, the original ACPRS used in step I was modified to the ACPRS used in step II. The final 8-item ACPRS is a valid, reliable (Cronbach α = 0.81) scale and has 2 primary factors. Women with medical power of attorney documents and living wills had higher ACPRS total scores than those who did not have these advance directives (P = 0.0030). Women with do-not-resuscitate (DNR) orders had higher ACPRS total scores than women without DNRs (P = 0.0176). CONCLUSIONS: The ACPRS is a valid and reliable 8-item scale that assesses the readiness of gynecologic oncology patients to discuss advance care planning issues.

RESUMEN

OBJECTIVE: The aim of this study was to assess treatment patterns, outcomes, and costs for bowel obstruction in ovarian cancer. METHODS/MATERIALS: All patients with stage II to IV ovarian cancer who were admitted for bowel obstruction greater than or equal to 6 months after cancer diagnosis from 2000 to 2011 were identified from the Surveillance, Epidemiology, and End Results registry-Medicare database. Management strategies and outcomes of bowel obstruction were compared. RESULTS: Among 1397 women with bowel obstruction, 562 (40%) underwent surgery, and 154 (11%) had a gastrostomy or jejunostomy (G/J) tube placed. Thirty-four percent of patients who underwent surgery subsequently received chemotherapy, compared with 8% of those managed with a G/J tube (odds ratio, 4.8; 95% confidence interval [CI], 2.7-8.8). Thirty-day complications were higher for patients in the surgery group compared with those in the tube group (69% vs 46%; odds ratio, 2.5; 95% CI, 1.8-3.7), as were mean adjusted 30-day total costs ($28,872 vs $18,528, P < 0.001). Median survival was greater for women who underwent surgery compared with those who had a G/J tube (5.3 vs 1.2 months; adjusted hazard ratio, 0.31; 95% CI, 0.25-0.38). The median survival of patients in whom surgical correction failed and required G/J tube placement during the same inpatient admission was 2.6 months. Women who received postintervention chemotherapy had improved survival compared with those who did not in both the surgery (17.0 vs 2.8 months, P < 0.001) and G/J tube (5.7 vs 1.0 months, P < 0.001) groups. CONCLUSIONS: In women with ovarian cancer who develop bowel obstruction, surgery may benefit a subset of patients, likely related to the ability to receive subsequent chemotherapy. Efforts to identify those who derive no benefit may reduce unnecessary laparotomy, along with its associated complications and costs. Given this population's limited survival, patient preferences should be evaluated in future studies assessing the management of bowel obstruction.
