RESUMEN
OBJECTIVE: To assess the effect of a practice-level preoperative frailty screening and optimization toolkit (OPTI-Surg) on postoperative functional recovery and complications in elderly cancer patients undergoing major surgery. SUMMARY BACKGROUND DATA: Frailty is common in older adults. it increases risk for poor postoperative functional recovery and complications. The potential for a practice-level screening/optimization intervention to improve outcomes is unknown. METHODS: Thoracic, gastrointestinal, and urologic oncological surgery practices within the NCI Community Oncology Research Program (NCORP) were randomized 1:1:1, to usual care (UC), OPTI-Surg, or OPTI-Surg with implementation coach. OPTI-Surg consisted of the Edmonton Frail Scale and guided recommendations for referral interventions. Patients ≥70 years old undergoing curative intent surgery were eligible. Primary outcome was 8 weeks postoperative function (kCal/week). Key secondary outcome was complications within 90 days. Mixed models were used to compare UC to the 2 OPTI-Surg arms combined. RESULTS: From 7/2019 to 9/2022, 325 patients were enrolled from 29 practices. 199 (64 UC, 135 OPTI-Surg) and 279 (78 UC, 201 OPTI-Surg) were evaluable for primary and secondary analysis, respectively. UC and OPTI-Surg patients did not significantly differ on total caloric expenditure (2.2 UC, 2.0 OPTI-Surg) after adjusting for baseline function (P=0.53). UC and OPTI-Surg patients did not significantly differ on postoperative complications (25.6% UC, 35.3% OPTI-Surg, P=0.5). CONCLUSIONS: Frailty assessment was successfully performed, but the OPTI-Surg intervention did not improve postoperative function nor reduce postoperative complications compared to UC. Future analysis will explore practice-level factors associated with toolkit implementation and differences between the coaching and non-coaching arms.
RESUMEN
Background: Music therapy (MT) offers benefits of improved symptom relief and quality of life at the end of life, but its impact on hospice patients and caregivers needs more research. Objective: To assess the impact of MT intervention on symptom burden and well-being of hospice patients and caregivers. Methods: A total of 18 hospice patients, selected based on scores ≥4 on the revised Edmonton Symptom Assessment System (ESAS-r) items on pain, depression, anxiety, or well-being, participated in MT sessions provided by a board-certified music therapist. Over a period of 2-3 weeks, 3-4 MT sessions were conducted for each. Patient Quality of life (QOL) was assessed using the Linear Analogue Self-Assessment (LASA). Depression and anxiety were measured with the Patient Health Questionnaire-4 (PHQ-4). For the 7 caregivers enrolled, stress levels were measured using the Pearlin role overload measure and LASA. Results: Patients reported a reduction in symptom severity and emotional distress and an increase in QOL. All patients endorsed satisfaction with music therapy, describing it as particularly beneficial for stress relief, relaxation, spiritual support, emotional support, and well-being. Scores on overall QOL and stress were worse for caregivers. Conclusion: This study provides evidence that MT reduces symptom burden and enhances the quality of life for hospice patients. Hospice patients and their caregivers endorsed satisfaction with MT. Given the benefits observed, integrating MT into hospice care regimens could potentially improve patient and caregiver outcomes. Larger studies should be conducted to better assess the impact of MT in this population.
RESUMEN
Importance: Adding fulvestrant to anastrozole (A+F) improved survival in postmenopausal women with advanced estrogen receptor (ER)-positive/ERBB2 (formerly HER2)-negative breast cancer. However, the combination has not been tested in early-stage disease. Objective: To determine whether neoadjuvant fulvestrant or A+F increases the rate of pathologic complete response or ypT1-2N0/N1mic/Ki67 2.7% or less residual disease (referred to as endocrine-sensitive disease) over anastrozole alone. Design, Setting, and Participants: A phase 3 randomized clinical trial assessing differences in clinical and correlative outcomes between each of the fulvestrant-containing arms and the anastrozole arm. Postmenopausal women with clinical stage II to III, ER-rich (Allred score 6-8 or >66%)/ERBB2-negative breast cancer were included. All analyses were based on data frozen on March 2, 2023. Interventions: Patients received anastrozole, fulvestrant, or a combination for 6 months preoperatively. Tumor Ki67 was assessed at week 4 and optionally at week 12, and if greater than 10% at either time point, the patient switched to neoadjuvant chemotherapy or immediate surgery. Main Outcomes and Measures: The primary outcome was the endocrine-sensitive disease rate (ESDR). A secondary outcome was the percentage change in Ki67 after 4 weeks of neoadjuvant endocrine therapy (NET) (week 4 Ki67 suppression). Results: Between February 2014 and November 2018, 1362 female patients (mean [SD] age, 65.0 [8.2] years) were enrolled. Among the 1298 evaluable patients, ESDRs were 18.7% (95% CI, 15.1%-22.7%), 22.8% (95% CI, 18.9%-27.1%), and 20.5% (95% CI, 16.8%-24.6%) with anastrozole, fulvestrant, and A+F, respectively. Compared to anastrozole, neither fulvestrant-containing regimen significantly improved ESDR or week 4 Ki67 suppression. The rate of week 4 or week 12 Ki67 greater than 10% was 25.1%, 24.2%, and 15.7% with anastrozole, fulvestrant, and A+F, respectively. Pathologic complete response/residual cancer burden class I occurred in 8 of 167 patients and 17 of 167 patients, respectively (15.0%; 95% CI, 9.9%-21.3%), after switching to neoadjuvant chemotherapy due to week 4 or week 12 Ki67 greater than 10%. PAM50 subtyping derived from RNA sequencing of baseline biopsies available for 753 patients (58%) identified 394 luminal A, 304 luminal B, and 55 nonluminal tumors. A+F led to a greater week 4 Ki67 suppression than anastrozole alone in luminal B tumors (median [IQR], -90.4% [-95.2 to -81.9%] vs -76.7% [-89.0 to -55.6%]; P < .001), but not luminal A tumors. Thirty-six nonluminal tumors (65.5%) had a week 4 or week 12 Ki67 greater than 10%. Conclusions and Relevance: In this randomized clinical trial, neither fulvestrant nor A+F significantly improved the 6-month ESDR over anastrozole in ER-rich/ERBB2-negative breast cancer. Aromatase inhibition remains the standard-of-care NET. Differential NET response by PAM50 subtype in exploratory analyses warrants further investigation. Trial Registration: ClinicalTrials.gov Identifier: NCT01953588.

BACKGROUND: Music therapy (MT) can relieve distressing end-of-life symptoms, but little is known regarding its effect on caregivers who are at risk for emotional distress as their loved ones approach death. MEASURES: Quality of life (Linear Analogue Self-Assessment), depressive and anxiety symptoms (Patient Health Questionnaire for Depression and Anxiety), and stress (Role Overload Measure) pre-MT, post-MT and at 6-month follow-up, as well as a satisfaction survey post-MT. INTERVENTION: Single MT session for 20-45 minutes OUTCOMES: 15/20 completed MT intervention, 14 also completed pre-MT and post-MT assessments, and 9 completed assessments at all 3 timepoints. Post-MT satisfaction survey (n=14) showed 100% of caregivers were very satisfied with MT and would recommend to others, and found MT very effective for emotional support (85.7%), stress relief (78.6%), spiritual support (71.4%), general feeling of wellness (71.4%), relaxation (69.2%), and pain relief (33.3%). CONCLUSIONS: Research on MT is feasible for caregivers of inpatient hospice patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03322228.

PURPOSE: Bone marrow biopsies (BMB) are performed before/after therapy to confirm complete response (CR) in patients with lymphoma on clinical trials. We sought to establish whether BMB add value in assessing response or predict progression-free survival (PFS) or overall survival (OS) outcomes in follicular lymphoma (FL) subjects in a large, multicenter, multitrial cohort. METHODS: Data were pooled from seven trials of 580 subjects with previously untreated FL through Alliance for Clinical Trials in Oncology (Alliance) and SWOG Cancer Research Network (SWOG) completing enrollment from 2008 to 2016. RESULTS: Only 5/580 (0.9%) had positive baseline BMB, CR on imaging, and subsequent positive BMB (P < .0001). Therefore, BMB were irrelevant to response in 99% of subjects. A sensitivity analysis of 385 FL subjects treated on an Eastern Cooperative Oncology Group study was included. In the Eastern Cooperative Oncology Group cohort, 5/385 (1.3%) had BMB that affected response assessment. Since some subjects do not undergo confirmatory BMB, we performed a landmark survival analysis from first radiologic CR with data from 580 subjects from Alliance and SWOG. Of subjects with CR on imaging (n = 187), PFS and OS were not significantly different among those with negative BMB to confirm CR (n = 47) versus those without repeat BMB (n = 140; PFS: adjusted hazard ratio, 1.10, 95% CI, 0.62 to 1.94, log-rank P = .686; OS: hazard ratio, 0.59, 95% CI, 0.23 to 1.53, log-rank P = .276). CONCLUSION: We conclude that BMB add little value to response assessment in subjects with FL treated on clinical trials and we recommend eliminating BMB from clinical trial requirements. BMB should also be removed from diagnostic guidelines for FL except in scenarios in which it may change management including confirmation of limited stage and assessment of cytopenias. This would reduce cost, patient discomfort, resource utilization, and potentially remove a barrier to trial enrollment.

PURPOSE: Patients with bulky stage I/II classic Hodgkin lymphoma (cHL) are typically treated with chemotherapy followed by radiation. Late effects associated with radiotherapy include increased risk of second cancer and cardiovascular disease. We tested a positron emission tomography (PET)-adapted approach in patients with bulky, early-stage cHL, omitting radiotherapy in patients with interim PET-negative (PET-) disease and intensifying treatment in patients with PET-positive (PET+) disease. METHODS: Eligible patients with bulky disease (mass > 10 cm or 1/3 the maximum intrathoracic diameter on chest x-ray) received two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by interim fluorodeoxyglucose PET (PET2). Patients with PET2-, defined as 1-3 on the 5-point scale, received four additional cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine. Patients with PET2+ received four cycles of escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone followed by 30.6 Gy involved-field radiation. RESULTS: Of 94 evaluable patients, 53% were female with median age 30 years (range, 18-58 years). Eight-five (90%) had stage II disease, including 48 (51%) with stage IIB/IIBE. Seventy-eight (78%) were PET2- and 21 (22%) were PET2+. The predominant toxicity was neutropenia, with 9% of patients developing febrile neutropenia and one developing sepsis. The primary end point of 3-year progression-free survival (PFS) was 93.1% in PET2- and 89.7% in PET2+ patients. Three-year overall survival was 98.6% and 94.4%, respectively. The estimated hazard ratio comparing PFS of patients with PET2+ and patients with PET2- was 1.03 (85% upper bound 2.38) and was significantly less than the null hypothesis of 4.1 (one-sided P = .04). CONCLUSION: Our study of PET-adapted therapy in bulky stage I/II cHL met its primary goal and was associated with an excellent 3-year PFS rate of 92.3% in all patients, with the majority being spared radiotherapy and exposure to intensified chemotherapy.

INTRODUCTION: Alliance for Clinical Trials in Oncology (Alliance) coordinated trials utilize Medidata Rave® (Rave) as the primary clinical data capture system. A growing number of innovative and complex cancer care delivery research (CCDR) trials are being conducted within the Alliance with the aims of studying and improving cancer-related care. Because these trials encompass patients, providers, practices, and their interactions, a defining characteristic of CCDR trials is multilevel data collection in pragmatic settings. Consequently, CCDR trials necessitated innovative strategies for database development, centralized data management, and data monitoring in the presence of these real-world multilevel relationships. Having real trial experience in working with community and academic centers, and having recently implemented five CCDR trials in Rave, we are committed to sharing our strategies and lessons learned in implementing such pragmatic trials in oncology. METHODS: Five Alliance CCDR trials are used to describe our approach to analyzing the database development needs and the novel strategies applied to overcome the unanticipated challenges we encountered. The strategies applied are organized into 3 categories: multilevel (clinic, clinic stakeholder, patient) enrollment, multilevel quantitative and qualitative data capture, including nontraditional data capture mechanisms being applied, and multilevel data monitoring. RESULTS: A notable lesson learned in each category was (1) to seek long-term solutions when developing the functionality to push patient and non-patient enrollments to their respective Rave study database that affords flexibility if new participant types are later added; (2) to be open to different data collection modalities, particularly if such modalities remove barriers to participation, recognizing that additional resources are needed to develop the infrastructure to exchange data between that modality and Rave; and (3) to facilitate multilevel data monitoring, orient site coordinators to the their trial's multiple study databases, each corresponding to a level in the hierarchy, and remind them to establish the link between patient and non-patient participants in the site-facing NCI web-based enrollment system. CONCLUSION: Although the challenges due to multilevel data collection in pragmatic settings were surmountable, our shared experience can inform and foster collaborations to collectively build on our past successes and improve on our past failures to address the gaps.

BACKGROUND: Older adults are under-represented in cancer clinical trials. However, it remains unclear which types of trials under-enroll aging patients. We aimed to identify associations between trial characteristics and disparate enrollment of older adults onto trials sponsored by the Alliance for Clinical Trials in Oncology (Alliance). METHODS: Actual age ≥ 65 percentage and trial data were extracted from the Alliance closed study list. Each trial, based on its cancer type and years of enrollment, was assigned an expected age ≥ 65 percentage extracted from the Surveillance, Epidemiology, and End Results (SEER) US population-based database. Enrollment disparity difference (EDD), the difference between the expected age ≥ 65 percentage and the actual age ≥ 65 percentage, was calculated for each trial. Linear regression determined trial variables associated with larger EDDs and variables with an overall association p-value <0.20 were included in a multivariable fixed-effects linear model. RESULTS: The median age of 66,708 patients across 237 trials was 60 years (range 18-102). The average actual age ≥ 65 percentage enrolled per trial was lower than each trial's expected age ≥ 65 percentage average (39% vs. 58%; EDD 19, 95% CI 17.1-21.3%, p < 0.0001). In multivariable analyses, non-genitourinary (GU) cancer types (p < 0.001), trimodality+ trials (estimate 8.78, 95%CI 2.21-15.34, p = 0.009), and phase 2 trials (estimate 4.43 95% CI -0.06-8.91; p = 0.05) were all associated with larger EDDs. CONCLUSIONS: Disparate enrollment of older adults is not equal across cancer trials. Future strategies to improve older adult inclusion should focus on trial types associated with the highest disparate enrollment.

Evidence for massage therapy (MT) in hospice patients remains limited. We conducted a prospective pilot study on MTs impact on quality of life of hospice patients and caregivers. Patient-caregiver dyads were enrolled if patients scored ≥5 on pain, depression, anxiety, or well-being using the revised Edmonton Symptom Assessment System Revised (ESAS-r). The patient received MT weekly for up to 3 massages with assessments completed at baseline, after each massage, and 1 week after the final massage for patients and at baseline and 1 week after final massage for caregivers. A satisfaction survey was completed at study completion. A pro-rated area under the curve (AUC) was utilized to assess the primary endpoints of change in ESAS-r for patient ratings of pain, depression and anxiety as well as the Linear Analogue Self-Assessment (LASA). Median difference scores (end of study value)-(baseline value) for each participant and caregiver were calculated. Of 27 patients and caregivers enrolled, 25 patients received MT. Fifteen patients completed all 3 MT sessions and were given the final symptom assessment and satisfaction survey and their caregivers completed final assessments. The proportion of patients considered success (AUC > baseline) in the primary endpoints were the following: pain 40.9%, depression 40.9%, anxiety 54.5%, LASA 54.5%. Median difference scores were largely zero indicating no significant temporal change in symptoms. Patients were highly satisfied with MT. This pilot study indicated that MT was a feasible and well-received intervention in our population of patients with inadequately controlled symptoms.

BACKGROUND: Clinical guidelines recommend altering chemotherapy treatment by decreasing, delaying, or discontinuing dosing in patients who are experiencing chemotherapy-induced peripheral neuropathy. There are few data available on the clinical use of treatment alteration including the severity of CIPN at the time of treatment alteration. METHODS: This was a retrospective analysis of patients receiving oxaliplatin on the NCCTG N08CB trial. Neuropathy severity was assessed at each cycle by clinicians and patients. Patients were classified as (1) completed treatment without alteration, (2) dose reduction or delay due to neuropathy, (3) discontinuation due to neuropathy, (4) discontinuation for other toxicity, or (5) discontinuation for another reason (5). Comparisons focused primarily on patients with alteration due to neuropathy (groups 2 and/or 3) compared with patients who completed treatment without alteration (group 1). RESULTS: In 350 participants, 135 (39%) completed treatment without alteration, 70 (20%) had a dose reduction or delay due to neuropathy, and 35 (10%) discontinued early due to neuropathy. Clinician-assessed neuropathy severity was greater in patients at the time of dose reduction or delay compared with severity at the end of treatment in patients without alteration (p < 0.0001). Patient-reported neuropathy severity at cycle 4 was worse in patients who eventually had a reduction or delay as compared with patients who completed treatment without alteration (p = 0.017). CONCLUSIONS: Treatment alterations due to neuropathy are common in patients receiving oxaliplatin for colon cancer and are associated with clinician-assessed neuropathy severity. Rapid increases in patient-reported neuropathy severity indicate a potential need for monitoring and intervention. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT01099449 (NCCTG N08CB).

PURPOSE: The current project was developed to obtain natural history information regarding cisplatin-induced peripheral neuropathy in males with testicular/germ cell cancers and to compare such neuropathy data with similarly obtained data in patients receiving other chemotherapy drugs in similarly conducted clinical trials. METHODS: Patients without baseline neuropathy symptoms, who were initiating cisplatin-based chemotherapy, completed the EORTC CIPN 20 patient-reported instrument to evaluate chemotherapy-induced peripheral neuropathy (CIPN). Results were compared with EORTC CIPN 20 data obtained from independent study sets regarding patients receiving (1) paclitaxel, (2) combined paclitaxel and carboplatin, (3) oxaliplatin, or (4) a combination of doxorubicin and cyclophosphamide (AC). The last study set of patients on AC was selected to evaluate the use of EORTC CIPN 20 data in patients receiving chemotherapy not known to cause CIPN. RESULTS: Cisplatin-induced neuropathy was more similar to neuropathy in patients receiving oxaliplatin than in those receiving paclitaxel. The cisplatin and oxaliplatin groups exhibited the coasting phenomenon and more prominent upper extremity symptoms than lower extremity symptoms during chemotherapy administration weeks. In contrast, paclitaxel-treated patients did not, on average, exhibit the coasting phenomenon; additionally, lower extremity symptoms were more prominent during the weeks when paclitaxel was administered. Cisplatin-induced neuropathy was less severe than was seen in patients in the other two groups, potentially because the cisplatin-receiving patients were younger. Patients receiving AC did not report substantial EORTC CIPN 20 changes. CONCLUSION: Understanding neuropathy similarities and differences with various chemotherapy agents may help elucidate CIPN processes and facilitate means to prevent and/or treat established CIPN. TRIAL REGISTRATION: NCT02677727.

PURPOSE: The objectives of this study were to evaluate the feasibility and efficacy of fractional CO2 laser therapy in gynecologic cancer survivors. METHODS: This was a pilot, multi-institutional randomized sham-controlled trial of women with gynecologic cancers with dyspareunia and/or vaginal dryness. Participants were randomized to fractional CO2 laser treatment or sham laser treatment. The primary aim was to estimate the proportion of patients who had improvement in symptoms based on the Vaginal Assessment Scale (VAS). Secondary aims included changes in sexual function assessed using the Female Sexual Functioning Index (FSFI) and urinary symptoms assessed using the the Urinary Distress Inventory (UDI-6). RESULTS: Eighteen women participated in the study, ten in the treatment arm and eight in the sham arm. The majority of participants had stage I (n = 11, 61.1 %) or II (n = 3, 16.7 %) endometrial cancer with adenocarcinoma histology (n = 9, 50 %). In total, 15 (83.3 %) of the participants completed all treatments and follow-up visit. There was no difference in the change in the median VAS score from baseline to follow-up. However, there was an improvement in change in the median total FSFI score with treatment compared with sham (Δ 6.5 vs -0.3, p = 0.02). The change in the median UDI-6 score was lower in the treatment arm (Δ -14.6 vs -2.1, p = 0.17), but this was not statistically significant. There were no reported serious adverse events. CONCLUSIONS: Fractional CO2 laser therapy is feasible in gynecologic cancer survivors, with preliminary evidence of safety. In addition, there was preliminary evidence of improvement in sexual function compared with sham treatment. Clinicaltrial.gov Identifier: NCT03372720 (OSU-17261; NCI-2017-02051).

PURPOSE: This pilot trial aimed to assess if cooling hands and feet with crushed ice during receipt of paclitaxel helps prevent peripheral neuropathy. METHODS: This prospective, randomized trial compared cryotherapy to standard care in patients initiating paclitaxel weekly x 12. For those on cryotherapy, hands and feet were cooled starting 15â¯min prior to and ending 15â¯min after each paclitaxel dose. EORTC QLQ-CIPN20 was completed at baseline, weekly x12, then monthly x6. Area under the curve (AUC) was calculated for subscale scores, adjusting for baseline, and compared between arms (Wilcoxon rank-sum test). Cross-study comparisons used data from 2 prior similarly-conducted neuropathy trials. RESULTS: Forty-six patients were accrued. Three withdrew and one was ineligible. Of the remaining 42 (21 cryotherapy, 21 control), 39 (19 cryotherapy, 20 control) were analyzable for AUC. Cryotherapy was well tolerated, but the AUC of the CIPN20 sensory scores over 12 weeks of paclitaxel was not found to differ between the study arms (mean difference 3.45, 95% CI -3.13 to 10.02, pâ¯=â¯0.26). However, the control arm of the current trial experienced less neuropathy than did the placebo arms of two previous similar trials. When our cryotherapy arm was compared to the combined control arms from all three trials, the cryotherapy arm had less neuropathy (Wilcoxon Rank-Sum pâ¯=â¯0.01). CONCLUSION: While there was no difference in CIPN20 scores identified between the 2 study arms in the current phase II trial, further investigation is needed given that the control arm experienced less neuropathy than was expected.

BACKGROUND: Regorafenib confers an overall survival benefit in patients with refractory metastatic colorectal cancer; however, the adverse event profile of regorafenib has limited its use. Despite no supportive evidence, various dosing schedules are used clinically to alleviate toxicities. This study evaluated the safety and activity of two regorafenib dosing schedules. METHODS: In this randomised, multicentre, open-label, phase 2 study done in 39 outpatient cancer centres in the USA, adults aged 18 years or older with histologically or cytologically confirmed advanced or metastatic adenocarcinoma of the colon or rectum that was refractory to previous standard therapy, including EGFR inhibitors if KRAS wild-type, were enrolled. Eligible patients had an Eastern Cooperative Oncology Group performance status of 0-1 and had no previous treatment with regorafenib. Patients were randomly assigned (1:1:1:1) into four groups with two distinct regorafenib dosing strategies and two clobetasol usage plans, stratified by hospital. Regorafenib dosing strategies were a dose-escalation strategy (starting dose 80 mg/day orally with weekly escalation, per 40 mg increment, to 160 mg/day regorafenib) if no significant drug-related adverse events occurred and a standard-dose strategy (160 mg/day orally) for 21 days of a 28-day cycle. Clobetasol usage plans (0·05% clobetasol cream twice daily applied to palms and soles) were either pre-emptive or reactive. After randomisation to the four preplanned groups, using the Pocock and Simon dynamic allocation procedures stratified by the treating hospitals, we formally tested the interaction between the two interventions, dosing strategy and clobetasol usage. Given the absence of a significant interaction (p=0·74), we decided to pool the data for the pre-emptive and reactive treatment with clobetasol and compared the two dosing strategies (dose escalation vs standard dose). The primary endpoint was the proportion of evaluable patients (defined as those who were eligible, consented, and received any protocol treatment) initiating cycle 3 and was analysed per protocol. Superiority for dose escalation was declared if the one-sided p value with Fisher's exact test was less than 0·2. This trial is registered with ClinicalTrials.gov, number NCT02368886. This study is fully accrued but remains active. FINDINGS: Between June 2, 2015, and June 22, 2017, 123 patients were randomly assigned to treatment, of whom 116 (94%) were evaluable. The per-protocol population consisted of 54 patients in the dose-escalation group and 62 in the standard-dose group. At data cutoff on July 24, 2018, median follow-up was 1·18 years (IQR 0·98-1·57). The primary endpoint was met: 23 (43%, 95% CI 29-56) of 54 patients in the dose-escalation group initiated cycle 3 versus 16 (26%, 15-37) of 62 patients in the standard-dose group (one-sided p=0·043). The most common grade 3-4 adverse events were fatigue (seven [13%] patients in the dose-escalation group vs 11 [18%] in the standard-dose group), hand-foot skin reaction (eight [15%] patients vs ten [16%] patients), abdominal pain (nine [17%] patients vs four [6%] patients), and hypertension (four [7%] patients vs nine [15%] patients). 14 patients had at least one drug-related serious adverse event: six patients in the dose-escalation group and eight patients in the standard-dose group. There was one probable treatment-related death in the standard-dose group (myocardial infarction). INTERPRETATION: The dose-escalation dosing strategy represents an alternative approach for optimising regorafenib dosing with comparable activity and lower incidence of adverse events and could be implemented in clinical practice on the basis of these data.

Patient-derived xenografts (PDX) are generated in immune deficient mice and demonstrate histologic and molecular features similar to their corresponding human tumors. However, murine tumors (non-human) spontaneously occur in these models. 120 consecutive patients with high-risk primary breast cancer enrolled in the prospective neoadjuvant BEAUTY study had tumor tissue obtained at the time of diagnosis. These tumor cells, including initial tissue and subsequent generations, were injected into either NSG (n = 365) or NOD-SCID (n = 396) female mice. Mice with initial tumor growth sufficient for transfer to the 2nd generation underwent histologic review by pathologists, including Ki67 staining. After passaging the tumors for up to 4 generations, at least one primary mouse tumor was detected from 24 of the 54 PDX-lines, for a frequency of 3.2% (24 mice out of 761 mice), including murine lymphomas (n = 13), mammary tumors (n = 7), osteosarcomas (n = 2), and hemangiosarcomas (n = 2). While true PDX showed scattered strong staining with Ki67, murine tumors were Ki67 negative. No significant differences (p = 0.062) were observed comparing development of murine tumors in NOD-SCID (n = 8) vs NSG mice (n = 16). While PDX are a useful tool in cancer research, there is a potential for spontaneous murine tumors to arise, which could alter results of studies utilizing PDX. Morphologic review by a pathologist, potentially along with Ki67 staining, is necessary to ensure that tumor growth represents the desired PDX prior to use in downstream studies. This study is the first prospective study evaluating the frequency, type, and time frame for development of non-human tumors.
RESUMEN
BACKGROUND: This multicenter, randomized phase 2 trial evaluated complete responses (CRs), efficacy, and safety with ofatumumab and bendamustine and with ofatumumab, bendamustine, and bortezomib in patients with untreated, high-risk follicular lymphoma (FL). METHODS: Patients with grade 1 to 3a FL and either a Follicular Lymphoma International Prognostic Index (FLIPI) score of 2 with 1 lymph node >6 cm or an FLIPI score of 3 to 5 were randomized to arm A (ofatumumab, bendamustine, and maintenance ofatumumab) or to arm B (ofatumumab, bendamustine, bortezomib, and maintenance ofatumumab and bortezomib). RESULTS: One hundred twenty-eight patients (66 in arm A and 62 in arm B) received treatment. The median age was 61 years, and 61% had disease >6 cm; 29% had an FLIPI score of 2, and 71% had an FLIPI score of 3 to 5. In arm A, 86% completed induction, and 64% completed maintenance. In arm B, 66% and 52% completed induction and maintenance, respectively. Dose modifications were required in 65% and 89% in arms A and B, respectively. Clinically significant grade 3 to 4 toxicities included neutropenia (A, 36%; B, 31%), nausea/vomiting (A, 0%; B, 8%), diarrhea (A, 5%; B, 11%), and sensory neuropathy (A, 0%; B, 5%). The estimated CR rates were 62% (95% confidence interval [CI], 50%-74%) and 60% (95% CI, 47%-72%) in arms A and B, respectively (P = .68). With a median follow-up of 3.3 years, the estimated 2-year progression-free survival (PFS) and overall survival (OS) rates were 80% and 97%, respectively, for arm A and 76% and 91%, respectively, for arm B. CONCLUSIONS: The CR rates, PFS, and OS were not improved with the addition of bortezomib to ofatumumab and bendamustine in patients with high-risk FL. Although grade 3 to 4 toxicities were similar, more patients treated with bortezomib required dose modifications and early discontinuation.

BACKGROUND: There are multiple known individual- and practice-level barriers to enrollment of older patients with cancer to clinical trials, but little is known about how the clinical research workforce feels about potential higher-level strategy changes aimed to promote increased enrollment of older patients. SUBJECTS, MATERIALS, AND METHODS: We invited all 11,351 Alliance for Clinical Trials in Oncology ("Alliance") members to participate in an anonymous, web-based survey to examine awareness of current accrual patterns for older patients to clinical trials, to ascertain consensus on how to tackle enrollment challenges, and to provide the impetus for high-level changes to improve clinical trial accrual of older patients with cancer. RESULTS: During the period from February 28, 2017, to June 16, 2017, 1,146 Alliance members participated (response rate = 10%), including a national diverse sample of physicians, nurses, administrative/clinical research staff, and patient advocates with representation from community, academic, and rural sites. Overall, one third felt that >50% of clinical trial enrollees should be age ≥65, and 64.9% felt the Alliance could improve upon enrollment of older patients. The four most commonly ranked strategies to improve enrollment of older patients were creating more dedicated trials for this population (36.3%), minimizing exclusion criteria focused on comorbidity (35.5%), developing independent strategies for those aged ≥65 and for those aged ≥70 (33.2%), and requiring that most/all Alliance trials have a specific expansion cohort of older patients (30.0%). CONCLUSION: We anticipate that the recommendations from >1,000 Alliance members will continue to propel important strategy changes aimed to improve accrual of older patients with cancer to clinical trials. IMPLICATIONS FOR PRACTICE: This survey of the Alliance for Clinical Trials membership sought opinions on potential, large-scale, national strategies to improve accrual of older adults with cancer. Consensus was found around multiple strategies, including creating more dedicated trials for older patients, developing less stringent eligibility criteria, and mandating expansion cohorts of older patients within broader Alliance trials. It is anticipated that the recommendations from >1,000 Alliance members will continue to propel important strategy changes aimed to improve accrual of older patients with cancer to clinical trials.

BACKGROUND: Women with estrogen deficiencies can suffer from vaginal symptoms that negatively impact sexual health. This study evaluated vaginal dehydroepiandrosterone (DHEA) for alleviation of vaginal symptoms. METHODS: This three-arm randomized, controlled trial evaluated DHEA 3.25 mg and DHEA 6.5 mg, each compared to a plain moisturizer (PM) over 12 weeks, to improve the severity of vaginal dryness or dyspareunia, measured with an ordinal scale, and overall sexual health using the Female Sexual Function Index (FSFI). Postmenopausal women with a history of breast or gynecologic cancer who had completed primary treatment, had no evidence of disease, and reported at least moderate vaginal symptoms were eligible. The mean change from baseline to week 12 in the severity of vaginal dryness or dyspareunia for each DHEA dose was compared to PM and analyzed by two independent t tests using a Bonferroni correction. RESULTS: Four hundred sixty-four women were randomized. All arms reported improvement in either dryness or dyspareunia. Neither DHEA dose was statistically significantly different from PM at 12 weeks (6.25 mg, p = .08; 3.25 mg, p = 0.48), although a significant difference at 8 weeks for 6.5 mg DHEA was observed (p = 0.005). Women on the 6.5 mg arm of DHEA reported significantly better sexual health on the FSFI (p < 0.001). There were no significant differences in provider-graded toxicities and few significant differences in self-reported side effects. CONCLUSION: PM and DHEA improved vaginal symptoms at 12 weeks. However, vaginal DHEA, 6.5 mg, significantly improved sexual health. Vaginal DHEA warrants further investigation in women with a history of cancer.

BACKGROUND: Dehydroepiandrosterone (DHEA) is helpful for treating vaginal symptoms. This secondary analysis evaluated the impact of vaginal DHEA on hormone concentrations, bone turnover, and vaginal cytology in women with a cancer history. METHODS: Postmenopausal women, diagnosed with breast or gynecologic cancer, were eligible if they reported at least moderate vaginal symptoms. Participants could be on tamoxifen or aromatase inhibitors (AIs). Women were randomized to 3.25 versus 6.5 mg/day of DHEA versus a plain moisturizer (PM) control. Sex steroid hormone levels, biomarkers of bone formation, vaginal pH, and maturation index were collected at baseline and 12 weeks. Analysis included independent t tests and Wilcoxon rank tests, comparing each DHEA arm with the control. RESULTS: Three hundred forty-five women contributed evaluable blood and 46 contributed evaluable cytology and pH values. Circulating DHEA-S and testosterone levels were significantly increased in those on vaginal DHEA in a dose-dependent manner compared to PM. Estradiol was significantly increased in those on 6.5 mg/day DHEA but not in those on 3.25 mg/day DHEA (p < 0.05 and p = 0.05, respectively), and not in those on AIs. Biomarkers of bone formation were unchanged in all arms. Maturation of vaginal cells was 100% (3.25 mg/day), 86% (6.5 mg/day), and 64% (PM); pH decreased more in DHEA arms. CONCLUSION: DHEA resulted in increased hormone concentrations, though still in the lowest half or quartile of the postmenopausal range, and provided more favorable effects on vaginal cytology, compared to PM. Estrogen concentrations in women on AIs were not changed. Further research on the benefit of vaginal DHEA is warranted in hormone-dependent cancers.
