RESUMEN

INTRODUCTION: Early reports of PD-1 inhibition in ovarian clear cell carcinomas (OCCC) demonstrate promising response. We evaluated the combination of pembrolizumab and IDO-1 inhibitor epacadostat in patients with recurrent OCCC. METHODS: This single arm, two-stage, phase 2 trial included those with measurable disease and 1-3 prior regimens. Patients received intravenous pembrolizumab 200 mg every 3 weeks and oral epacadostat 100 mg twice a day. Primary endpoint was overall response rate (ORR), secondary endpoints were toxicity, progression-free survival (PFS) and overall survival (OS). The study was powered to detect an absolute 25% increase in response (15% to 40%). RESULTS: Between September 28, 2018 and April 10, 2019, 14 patients enrolled at first stage. Rate of accrual was 2.3 patients per month. Median age was 65 years (44-89), 10 (71.4%) had ≥2 prior regimens. ORR was 21% (95% CI 5-51%) within 7 months of study entry with 3 partial responses, and 4 had stable disease (disease control rate 50%). Median PFS was 4.8 months (95% CI: 1.9-9.6), OS 18.9 months (95% CI: 1.9-NR). Most common grade ≥ 3 adverse events were electrolyte abnormalities and gastrointestinal pain, nausea, vomiting, bowel obstruction. In July 2019, the study reached the pre-specified criteria to re-open to second stage; however, the study closed prematurely in February 2021 due to insufficient drug supply. CONCLUSIONS: Pembrolizumab and epacadostat demonstrated an ORR of 21% in this small cohort of recurrent OCCC. The rapid rate of accrual highlights the enthusiasm and need for therapeutic studies in patients with OCCC.

RESUMEN

PURPOSE: Pelvic recurrence is a frequent pattern of relapse for women with endometrial cancer. A randomized trial compared progression-free survival (PFS) after treatment with radiation therapy alone as compared with concurrent chemotherapy. MATERIALS AND METHODS: Between February 2008 and August 2020, 165 patients were randomly assigned 1:1 to receive either radiation treatment alone or a combination of chemotherapy and radiation treatment. The primary objective of this study was to determine whether chemoradiation therapy was more effective than radiation therapy alone at improving PFS. RESULTS: The majority of patients had low-grade (1 or 2) endometrioid histology (82%) and recurrences confined to the vagina (86%). External beam with either the three-dimensional or intensity modulated radiation treatment technique was followed by a boost delivered with brachytherapy or external beam. Patients randomly assigned to receive chemotherapy were treated with once weekly cisplatin (40 mg/m2). Rates of acute toxicity were higher in patients treated with chemoradiation as compared with radiation treatment alone. Median PFS was longer for patients treated with radiation therapy alone as compared with chemotherapy and radiation (median PFS was not reached for RT v 73 months for chemoradiation, hazard ratio of 1.25 (95% CI, 0.75 to 2.07). At 3 years, 73% of patients treated definitively with radiation and 62% of patients treated with chemoradiation were alive and free of disease progression. CONCLUSION: Excellent outcomes can be achieved for women with localized recurrences of endometrial cancer when treated with radiation therapy. The addition of chemotherapy does not improve PFS for patients treated with definitive radiation therapy for recurrent endometrial cancer and increases acute toxicity. Patients with low-grade and vaginal recurrences who constituted the majority of those enrolled are best treated with radiation therapy alone.

RESUMEN

PURPOSE: This paper reports the efficacy of the poly (ADP-ribose) polymerase inhibitor olaparib alone and in combination with the antiangiogenesis agent cediranib compared with cediranib alone in patients with advanced endometrial cancer. METHODS: This was open-label, randomized, phase 2 trial (NCT03660826). Eligible patients had recurrent endometrial cancer, received at least one (<3) prior lines of chemotherapy, and were Eastern Cooperative Oncology Group performance status 0 to 2. Patients were randomly assigned (1:1:1), stratified by histology (serous vs. other) to receive cediranib alone (reference arm), olaparib, or olaparib and cediranib for 28-day cycles until progression or unacceptable toxicity. The primary end point was progression-free survival in the intention-to-treat population. Homologous repair deficiency was explored using the BROCA-GO sequencing panel. RESULTS: A total of 120 patients were enrolled and all were included in the intention-to-treat analysis. Median age was 66 (range, 41-86) years and 47 (39.2%) had serous histology. Median progression-free survival for cediranib was 3.8 months compared with 2.0 months for olaparib (hazard ratio, 1.45 [95% CI, 0.91-2.3] p = .935) and 5.5 months for olaparib/cediranib (hazard ratio, 0.7 [95% CI, 0.43-1.14] p = .064). Four patients receiving the combination had a durable response lasting more than 20 months. The most common grade 3/4 toxicities were hypertension in the cediranib (36%) and olaparib/cediranib (33%) arms, fatigue (20.5% olaparib/cediranib), and diarrhea (17.9% cediranib). The BROCA-GO panel results were not associated with response. CONCLUSION: The combination of cediranib and olaparib demonstrated modest clinical efficacy; however, the primary end point of the study was not met. The combination was safe without unexpected toxicity.

RESUMEN

BACKGROUND: The remaining lifetime risk (RLR) is the probability of developing an outcome over the remainder of one's lifespan at any given age. The RLR for atherosclerotic cardiovascular disease (ASCVD) in three 20-year periods were assessed using data from a single community-based cohort study of predominantly White participants. METHODS: Longitudinal data from the Framingham study in 3 epochs (epoch 1, 1960-1979; epoch 2, 1980-1999; epoch 3, 2000-2018) were evaluated. The RLR of a first ASCVD event (myocardial infarction, coronary heart disease death, or stroke) from 45 years of age (adjusting for competing risk of death) in the 3 epochs were compared overall, and according to the following strata: sex, body mass index, blood pressure and cholesterol categories, diabetes, smoking, and Framingham risk score groups. RESULTS: There were 317 849 person-years of observations during the 3 epochs (56% women; 94% White) and 4855 deaths occurred. Life expectancy rose by 10.1 years (men) to 11.9 years (women) across the 3 epochs. There were 1085 ASCVD events over the course of 91 330 person-years in epoch 1, 1330 ASCVD events over the course of 107 450 person-years in epoch 2, and 775 ASCVD events over the course of 119 069 person-years in epoch 3. The mean age at onset of first ASCVD event was greater in the third epoch by 8.1 years (men) to 10.3 years (women) compared with the first epoch. The RLR of ASCVD from 45 years of age declined from 43.7% in epoch 1 to 28.1% in epoch 3 (P<0.0001), a finding that was consistent in both sexes (RLR [epoch 1 versus epoch 3], 36.3% versus 26.5% [women]; 52.5% versus 30.1% [men]; P<0.001 for both). The lower RLR of ASCVD in the last 2 epochs was observed consistently across body mass index, blood pressure, cholesterol, diabetes, smoking, and Framingham risk score strata (P<0.001 for all). The RLR of coronary heart disease events and stroke declined in both sexes (P<0.001). CONCLUSIONS: Over the past 6 decades, mean life expectancy increased and the RLR of ASCVD decreased in the community-based, predominantly White Framingham study. The residual burden of ASCVD underscores the importance of continued and effective primary prevention efforts with better screening for risk factors and their effective treatment.

RESUMEN

BACKGROUND: The residual lifetime risk (RLR) of developing heart failure (HF) may have changed over time because of the increasing population burden of hypertension, obesity, and diabetes; greater survival after myocardial infarction; and a greater lifespan. OBJECTIVES: The authors assessed changes in the RLR for HF in two 25-year epochs (1965-1989 and 1990-2014). METHODS: We compared the RLR of HF at age 50 years (adjusting for competing risk of death) in the 2 epochs in Framingham Study participants overall and in the following strata: sex, body mass index, blood pressure, and diabetes. RESULTS: Mean life expectancy increased from 75.9 to 82.1 years in women and 72.5 to 78.1 years in men. We observed 624 HF events over 111,351 person-observations in epoch 1, and 875 HF events over 128,903 person-observations in epoch 2. The mean age at onset of HF increased across the epochs by 6.6 years (women) to 7.2 years (men). The RLR of HF at age 50 years increased across epochs from 18.86% to 22.55% (absolute increase 3.69; 95% CI: 0.90-6.49; P = 0.01) in women, and from 19.19% to 25.25% (absolute increase 6.06; 95% CI: 3.08-9.04; P < 0.001) in men. The increase in RLR of HF in the second epoch was consistent across strata with excess body mass index or higher blood pressure (relative increase of 28%-47%) and in participants without prior myocardial infarction (relative increase of 23%). CONCLUSIONS: The RLR of HF has increased in our community-based sample of White individuals over the last 5 decades, possibly caused by an increase in life expectancy.

RESUMEN

Clinical trials typically collect longitudinal data, data that are collected repeated over time, such as laboratories, scans, or patient-reported outcomes. Due to a variety of reasons, this data can be missing, whether a patient stops attending clinical visits (ie, dropout) or misses assessments intermittently. Understanding the reasons for missing data as well as predictors of missing data can aid in determination of the missing data mechanism. The analysis methods used are dependent on the missing data mechanism and may make certain assumptions about the missing data itself. Methods for nonignorable missing data, which assumes that the missing data depend on the missing data itself, make stronger assumptions and include pattern-mixture models and shared parameter models. Missing data that are ignorable after adjusting for other covariates can be analyzed using methods that adjust for covariates, such as mixed-effects models or multiple imputation. Missing data that are ignorable can be analyzed using standard approaches that require complete case data, such as change from baseline or proportion of patients who declined at a specified time point. In clinical trials, truly ignorable data are rare, resulting in additional analysis methods required for proper interpretation of the results. Conducting several analyses under different assumptions, called sensitivity analyses, can determine the extent of the impact of the missing data.

RESUMEN

BACKGROUND: Age and ethnicity are among several factors that influence overall survival (OS) in ovarian cancer. The study objective was to determine whether ethnicity and age were of prognostic significance in women enrolled in a clinical trial evaluating the addition of bevacizumab to front-line therapy. METHODS: Women with advanced stage ovarian, primary peritoneal, or fallopian tube cancer were enrolled in a phase III clinical trial. All women had surgical staging and received adjuvant chemotherapy with one of three regimens. Cox proportional hazards models were used to evaluate the relationship between OS with age and race/ethnicity among the study participants. RESULTS: One-thousand-eight-hundred-seventy-three women were enrolled in the study. There were 280 minority women and 328 women over the age of 70. Women age 70 and older had a 34% increase risk for death when compared to women under 60 (HR = 1.34; 95% CI 1.16-1.54). Non-Hispanic Black women had a 54% decreased risk of death with the addition of maintenance bevacizumab (HR = 0.46, 95% CI:0.26-0.83). Women of Asian descent had more hematologic grade 3 or greater adverse events and a 27% decrease risk of death when compared to non-Hispanic Whites (HR = 0.73; 95% CI: 0.59-0.90). CONCLUSIONS: Non-Hispanic Black women showed a decreased risk of death with the addition of bevacizumab and patients of Asian ancestry had a lower death rate than all other minority groups, but despite these clinically meaningful improvements there was no statistically significant difference in OS among the groups.

RESUMEN

PURPOSE: Increasing measures of adiposity have been correlated with poor oncologic outcomes and a lack of response to anti-angiogenic therapies. Limited data exists on the impact of subcutaneous fat density (SFD) and visceral fat density (VFD) on oncologic outcomes. This ancillary analysis of GOG-218, evaluates whether imaging markers of adiposity were predictive biomarkers for bevacizumab (bev) use in epithelial ovarian cancer (EOC). PATIENTS AND METHODS: There were 1249 patients (67%) from GOG-218 with imaging measurements. SFD and VFD were calculated utilizing Hounsfield units (HU). Proportional hazards models were used to assess the association between SFD and VFD with overall survival (OS). RESULTS: Increased SFD and VFD showed an increased HR for death (HR per 1-SD increase 1.12, 95% CI:1.05-1.19 p = 0.0009 and 1.13, 95% CI: 1.05-1.20 p = 0.0006 respectively). In the predictive analysis for response to bev, high VFD showed an increased hazard for death in the placebo group (HR per 1-SD increase 1.22, 95% CI: 1.09-1.37; p = 0.025). However, in the bev group there was no effect seen (HR per 1-SD increase: 1.01, 95% CI: 0.90-1.14) Median OS was 45 vs 47 months in the VFD low groups and 36 vs 42 months in the VFD high groups on placebo versus bev, respectively. CONCLUSION: High VFD and SFD have a negative prognostic impact on patients with EOC. High VFD appears to be a predictive marker of bev response and patients with high VFD may be more likely to benefit from initial treatment with bev.

RESUMEN

Practice changing standardization of lower extremity lymphedema quantitative measurements with integrated patient reported outcomes will likely refine and redefine the optimal risk-reduction strategies to diminish the devastating limb-related dysfunction and morbidity associated with treatment of gynecologic cancers. The National Cancer Institute (NCI), Division of Cancer Prevention brought together a diverse group of cancer treatment, therapy and patient reported outcomes experts to discuss the current state-of-the-science in lymphedema evaluation with the potential goal of incorporating new strategies for optimal evaluation of lymphedema in future developing gynecologic clinical trials.

RESUMEN

PURPOSE: A phase I clinical trial (GOG-9929) examined the safety and efficacy of adjuvant immune-modulation therapy with the checkpoint inhibitor ipilimumab [anti-CTL antigen-4 (anti-CTLA-4)] following chemoradiation therapy (CRT) for newly diagnosed node-positive human papillomavirus (HPV)-related cervical cancer. To better understand the mechanism of action and to identify predictive biomarkers, immunologic and viral correlates were assessed before, during, and after treatment. PATIENTS AND METHODS: Twenty-one patients who received CRT and ≥2 doses of ipilimumab and 5 patients who received CRT only were evaluable for translational endpoints. Circulating T-cell subsets were evaluated by multiparameter flow cytometry. Cytokines were evaluated by multiplex ELISA. HPV-specific T cells were evaluated in a subset of patients by IFNγ ELISpot. RESULTS: Expression of the activation markers ICOS and PD-1 significantly increased on T-cell subsets following CRT and were sustained or increased following ipilimumab treatment. Combined CRT/ipilimumab treatment resulted in a significant expansion of both central and effector memory T-cell populations. Genotype-specific E6/E7-specific T-cell responses increased post-CRT in 1 of 8 HPV16+ patients and in 2 of 3 HPV18+ patients. Elevation in levels of tumor-promoting circulating cytokines (TNFα, IL6, IL8) post-CRT was significantly associated with worse progression-free survival. CONCLUSIONS: Our data indicate that CRT alone and combined with ipilimumab immunotherapy show immune-modulating activity in women with locally advanced cervical cancer and may be a promising therapeutic option for the enhancement of antitumor immune cell function after primary CRT for this population at high risk for recurrence and metastasis. Several key immune biomarkers were identified that were associated with clinical response.

RESUMEN

AIMS: We sought to describe the frequency, type and timing of clinical events, and delineate patterns in their transitions, after a first episode of heart failure (HF). METHODS AND RESULTS: In 1036 Framingham participants with new-onset HF (mean age 79 years; 53% women), we used mixture models to estimate probabilities of, and time to cardiac death, other cardiovascular disease (CVD) death, recurrent HF, cardiac events and other CVD events, accounting for age, sex, HF type (preserved vs. reduced ejection fraction), and prevalent cardiac/CVD events. The most common first events after new-onset HF were cardiac (36%), recurrent HF (28%) and death (29%). Compared with recurrent HF (referent transition state), prevalent cardiac events were associated with higher odds of fatal [odds ratio (OR) 1.90, 95% confidence interval (CI) 1.11-3.23] and non-fatal (OR 2.13, 95% CI 1.52-3.00) cardiac events; prevalent CVD increased odds of other CVD death (OR 1.90, 95% CI 1.04-3.47). Among 715 participants without a fatal initial event, there were 3337 distinct epochs (inter-event time periods), with median 3.0 epochs/participant [49% cardiac (n = 1639); 27% recurrent HF (n = 912)]. Median inter-event times varied between 12 to 285 days (recurrent HF to other CVD death and non-fatal other CVD, respectively). Prior HF, cardiac and other CVD events significantly increased odds of developing the same event-type (OR ∼ 5-7-fold), with shortened time to recurrence, indicating 'rapid cycling loops' of the same event type. HF type did not impact the nature or timing of future events. CONCLUSIONS: Comorbidities but not HF type impact clinical course of HF by influencing the type and timing of subsequent events, denoting 'natural history loops' within the overall HF population.

RESUMEN

IMPORTANCE: Despite standard chemoradiotherapy (CRT), most women with lymph node (LN)-positive cervical cancer experience disease recurrence. Immunotherapy is being investigated in the up-front treatment setting. OBJECTIVES: To assess the safety of sequential immunotherapy after CRT and to investigate human papillomavirus (HPV) genotype and HLA allele status on survival and programmed cell death 1 (PD-1) expression before and after CRT and sequential immunotherapy. DESIGN, SETTING, AND PARTICIPANTS: This prospective phase 1 trial conducted in 29 Gynecology Oncology Cooperative Group member institutions enrolled participants from December 18, 2012, to August 31, 2016, with a 14.8-month median follow-up and translational end points. Thirty-four women with International Federation of Gynecology and Obstetrics stage IB2 to IVA cervical cancer with positive pelvic LNs, para-aortic LNs, or both were enrolled; 13 did not receive ipilimumab and were excluded from the analysis. Data were analyzed from January 21 to April 4, 2018. INTERVENTIONS: Treatment consisted of 6 weekly doses of cisplatin, 40 mg/m2, concurrent with radiotherapy. After completion of chemotherapy, sequential ipilimumab was given every 21 days for 4 doses. Two dosage levels of ipilimumab, 3 mg/kg and 10 mg/kg, were studied to identify the maximum tolerated dose. MAIN OUTCOMES AND MEASURES: The primary end point was safety, and the secondary end points were overall survival and progression-free survival. Exploratory end points included HPV genotype, HLA allele status, and PD-1 expression measured in peripheral blood. RESULTS: The median age of the 32 participants included in the intent-to-treat analysis was 50 (range, 26-61) years, and 22 patients (69%) were white. Of the 21 patients who received ipilimumab, all had positive pelvic LN, and 6 (29%) had positive para-aortic LNs. All patients completed CRT, and of the 21 patients who received at least 2 cycles of ipilimumab, 18 (86%) completed 4 cycles of ipilimumab, and 3 (14%) completed 2 cycles. The maximum tolerated dose was 10 mg/kg. Two of the 21 patients (9.5%) who received ipilimumab had self-limiting grade 3 toxic effects (lipase increase; dermatitis). The 12-month overall survival was 90%, and progression-free survival was 81%. Human papillomavirus genotype and HLA subtype were not associated with progression-free survival or overall survival. T cells expressing PD-1 increased after CRT, and levels were sustained with ipilimumab. CONCLUSIONS AND RELEVANCE: This study's findings suggest that the use of immunotherapy after CRT for curative-intent treatment of patients with cervical cancer is tolerable and effective. The results indicated that PD-1 was upregulated after CRT and sustained with sequential ipilimumab therapy. These immune findings may help guide future therapies to harness the activated T-cell phenotype in patients with node-positive cervical cancer.

RESUMEN

BACKGROUND: Secondary surgical cytoreduction in women with platinum-sensitive, recurrent epithelial ovarian, primary peritoneal, or fallopian-tube ("ovarian") cancer is widely practiced but has not been evaluated in phase 3 investigation. METHODS: We randomly assigned patients with recurrent ovarian cancer who had received one previous therapy, had an interval during which no platinum-based chemotherapy was used (platinum-free interval) of 6 months or more, and had investigator-determined resectable disease (to no macroscopic residual disease) to undergo secondary surgical cytoreduction and then receive platinum-based chemotherapy or to receive platinum-based chemotherapy alone. Adjuvant chemotherapy (paclitaxel-carboplatin or gemcitabine-carboplatin) and use of bevacizumab were at the discretion of the investigator. The primary end point was overall survival. RESULTS: A total of 485 patients underwent randomization, 240 to secondary cytoreduction before chemotherapy and 245 to chemotherapy alone. The median follow-up was 48.1 months. Complete gross resection was achieved in 67% of the patients assigned to surgery who underwent the procedure. Platinum-based chemotherapy with bevacizumab followed by bevacizumab maintenance was administered to 84% of the patients overall and was equally distributed between the two groups. The hazard ratio for death (surgery vs. no surgery) was 1.29 (95% confidence interval [CI], 0.97 to 1.72; P = 0.08), which corresponded to a median overall survival of 50.6 months and 64.7 months, respectively. Adjustment for platinum-free interval and chemotherapy choice did not alter the effect. The hazard ratio for disease progression or death (surgery vs. no surgery) was 0.82 (95% CI, 0.66 to 1.01; median progression-free survival, 18.9 months and 16.2 months, respectively). Surgical morbidity at 30 days was 9%; 1 patient (0.4%) died from postoperative complications. Patient-reported quality of life decreased significantly after surgery but did not differ significantly between the two groups after recovery. CONCLUSIONS: In this trial involving patients with platinum-sensitive, recurrent ovarian cancer, secondary surgical cytoreduction followed by chemotherapy did not result in longer overall survival than chemotherapy alone.

RESUMEN

When comparing performances of two risk prediction models, several metrics exist to quantify prognostic improvement, including the change in the area under the Receiver Operating Characteristic curve, the Integrated Discrimination Improvement, the Net Reclassification Index at event rate, the change in Standardized Net Benefit, the change in Brier score, and the change in scaled Brier score. We explore the behavior and interrelationships between these metrics under multivariate normality in nested and nonnested model comparisons. We demonstrate that, within the framework of linear discriminant analysis, all six statistics are functions of squared Mahalanobis distance, a robust metric that properly measures discrimination by quantifying the separation between the risk scores of events and nonevents. These relationships are important for overall interpretability and clinical usefulness. Through simulation, we demonstrate that the performance of the theoretical estimators under normality is comparable or superior to empirical estimation methods typically used by investigators. In particular, the theoretical estimators for the Net Reclassification Index and the change in Standardized Net Benefit exhibit less variability in their estimates as compared to their empirically estimated counterparts. Finally, we explore how these metrics behave with potentially nonnormal data by applying these methods in a practical example based on the sex-specific cardiovascular disease risk models from the Framingham Heart Study. Our findings aim to give greater insight into the behavior of these measures and the connections existing among them and to provide additional estimation methods with less variability for the Net Reclassification Index and the change in Standardized Net Benefit.

RESUMEN

PURPOSE: We report the final, protocol-specified analysis of overall survival (OS) in GOG-0218, a phase III, randomized trial of bevacizumab in women with newly diagnosed ovarian, fallopian tube, or primary peritoneal carcinoma. METHODS: A total of 1,873 women with incompletely resected stage III to IV disease were randomly assigned 1:1:1 to six 21-day cycles of intravenous carboplatin (area under the concentration v time curve 6) and paclitaxel (175 mg/m2) versus chemotherapy plus concurrent bevacizumab (15 mg/kg, cycles 2 to 6) versus chemotherapy plus concurrent and maintenance bevacizumab (cycles 2 to 22). Inclusion criteria included a Gynecologic Oncology Group performance status of 0 to 2 and no history of clinically significant vascular events or evidence of intestinal obstruction. OS was analyzed in the intention-to-treat population. A total of 1,195 serum and/or tumor specimens were sequenced for BRCA1/2 and damaging mutations in homologous recombination repair (HRR) genes. Intratumoral microvessel density was studied using CD31 immunohistochemistry. RESULTS: Median follow-up was 102.9 months. Relative to control (n = 625), for patients receiving bevacizumab-concurrent (n = 625), the hazard ratio (HR) of death was 1.06 (95% CI, 0.94 to 1.20); for bevacizumab-concurrent plus maintenance (n = 623), the HR was 0.96 (95% CI, 0.85 to 1.09). Disease-specific survival was not improved in any arm. No survival advantage was observed after censoring patients who received bevacizumab at crossover or as second line. Median OS for stage IV bevacizumab-concurrent plus maintenance was 42.8 v 32.6 months for stage IV control (HR, 0.75; 95% CI, 0.59 to 0.95). Relative to wild type, the HR for death for BRCA1/2 mutated carcinomas was 0.62 (95% CI, 0.52 to 0.73), and for non-BRCA1/2 HRR, the HR was 0.65 (95% CI, 0.51 to 0.85). BRCA1/2, HRR, and CD31 were not predictive of bevacizumab activity. CONCLUSION: No survival differences were observed for patients who received bevacizumab compared with chemotherapy alone. Testing for BRCA1/2 mutations and homologous recombination deficiency is essential.

RESUMEN

The duty to recontact continues to be revisited in the field of clinical genetics and is currently relevant for cancer genetic counseling given the transition from single-gene to multi-gene panel testing. We recruited cancer genetic counselors through the National Society of Genetic Counselors list-serv to complete an online survey assessing current practices and perspectives regarding recontacting patients about diagnostic genetic tests. Forty-one percent of respondents reported that they have recontacted patients to offer updated (new) diagnostic genetic testing (40/97). A majority (61%, 17/28), of genetic counselors who reported recontact specifically for panel testing indicated that the availability of management recommendations for genes not previously tested routinely was an important factor in the decision to recontact. All respondents who recontacted patients reported "improved patient care" as a perceived benefit. Respondents indicated that recontact is mostly a patient responsibility (49%), followed by a shared responsibility between the provider and patient (43%). Few respondents (2%) reported a uniform ethical duty to recontact patients regarding new and updated testing, while the majority (89%) felt that there was some degree of ethical duty. A greater percentage of those who reported past recontact practices reported intention to recontact in the future (p = 0.001). There is little consensus among the genetic counselor respondents about how to approach the recontacting of patients to offer updated genetic testing.

RESUMEN

OBJECTIVES: To determine if the addition of paclitaxel (P) to cisplatin and doxorubicin (CD) following surgical debulking and volume-directed radiation therapy improved long-term, recurrence-free survival (RFS) and overall survival (OS) in patients with advanced-stage endometrial cancer (EC). METHODS: Prospective, randomized GOG trial comparing (CD) (50 mg/m2)/(45 mg/m2) +/- (P) (160 mg/m2) following volume-directed radiation and surgery in advanced EC. A Kaplan-Meier (KM) analysis characterized the relationship between treatment arms and the OS outcome, a log-rank test assessed the independence of treatment with the OS outcome, and the treatment effect on estimated OS was determined using a Cox proportional hazards (PH) model stratified by stage. The PH assumption was assessed using a test of interaction between treatment variable and the natural logarithm of survival time. Adverse events, regardless of attribution, were graded. RESULTS: Since initial publication, 60 deaths occurred, leaving 311 patients alive with 290 (93.8%) recurrence- free. There was no significant decrease in the risk of recurrence or death associated with the CDP treatment regimen stratified for stage (p = 0.14, one-tail). The exploratory analysis for OS and the corresponding homogeneity tests for different effects across subgroups revealed only EFRT and EFRT & GRD status to have significantly different treatment effects (p = 0.027 and p = 0.017, respectively). Second primary malignancies were identified in 17/253 (6.4%) and 19/263 (7.0%) of patients treated with CD and CDP respectively. Breast (2.4%) followed by colon (1%) were the two cancers most frequently diagnosed in this setting. CONCLUSION: No significant difference between treatment arms was identified. Subgroup analysis both in the initial and current reports demonstrated a trend towards improved RFS and OS in patients treated with CDP and EFRT. This long-term analysis of outcomes also identified the necessity of providing on-going cancer screening to patients enrolled in trials.

RESUMEN

BACKGROUND: Comprehensive conjoint characterization of long-term trajectories representing several biological systems is lacking. METHODS: We measured serially indicators representing 14 distinct biological systems in up to 3,453 participants attending four Framingham Study examinations: bone mineral density, body mass index (BMI), C-reactive protein, glomerular filtration rate, forced vital capacity (FVC), 1 second forced expiratory volume/FVC ratio (FEV1/FVC), gait speed, grip strength, glycosylated hemoglobin (HbA1c), heart rate, left ventricular mass, Mini-Mental State Examination (MMSE), pulse pressure, and total/high-density lipoprotein cholesterol ratio (TC/HDL). RESULTS: We observed that correlations among the 14 sex-specific trajectories were modest (r < .30 for 169 of 182 sex-specific correlations). During follow-up (median 8 years), 232 individuals experienced a cardiovascular disease (CVD) event and 393 participants died. In multivariable regression models, CVD incidence was positively related to trajectories of BMI, HbA1c, TC/HDL, gait time, and pulse pressure (p < .06); mortality risk was related directly to trajectories of gait time, C-reactive protein, heart rate, and pulse pressure but inversely to MMSE and FEV1/FVC (p < .006). A unit increase in the trajectory risk score was associated with a 2.80-fold risk of CVD (95% confidence interval [CI], 2.04-3.84; p < .001) and a 2.71-fold risk of death (95% CI, 2.30-3.20; p < .001). Trajectory risk scores were suggestive of a greater increase in model c-statistic compared with single occasion measures (delta-c compared with age- and sex-adjusted models: .032 vs .026 for CVD; .042 vs .030 for mortality). CONCLUSIONS: Biological systems age differentially over the life course. Longitudinal data on a parsimonious set of biomarkers reflecting key biological systems may facilitate identification of high-risk individuals.

RESUMEN

PURPOSE: We conducted a randomized phase III trial to determine whether adjuvant chemotherapy improves survival in women with uterine leiomyosarcoma. METHODS: Women with uterus-confined, high-grade leiomyosarcoma who were confirmed disease free by imaging were randomly assigned to four cycles of gemcitabine plus docetaxel, followed by four cycles of doxorubicin, or to observation. All were followed for evidence of recurrence. The primary end point was overall survival (OS). RESULTS: With international collaboration, 38 of the targeted accrual of 216 patients were enrolled, after which the study was closed by the National Cancer Institute for accrual futility. Twenty patients were assigned to chemotherapy, 18 to observation. Among the 17 patients treated with at least one cycle of chemotherapy, grade 3 or 4 toxicities were observed in 47%; among the 18 patients assigned to observation, one had grade 3 hypertension. There were six deaths (chemotherapy, n = 5; observation, n = 1), all due to disease. The restricted mean survival time for OS was estimated as 34.3 months (95% CI, 25.3 to 43.3 months) in the chemotherapy arm and as 46.4 months (95% CI, 43.6 to 49.1 months) in the observation arm. There were eight recurrences in each arm. The restricted mean survival time for recurrence-free survival was estimated as 18.1 (95% CI, 14.2 to 22.0) months in the chemotherapy arm and as 14.6 months (95% CI, 10.3 to 19.0 months) in the observation arm. Neither survival outcome comparison was considered statistically robust, due to the small sample size. CONCLUSION: Despite international collaboration to test the role of adjuvant chemotherapy in uterine-confined leiomyosarcoma, this study was closed for accrual futility. Although the sample size precludes robust statistical comparison, observed OS and recurrence-free survival data do not show superior outcomes with adjuvant chemotherapy.
