<h4>Background</h4>Patients with human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma have high survival when treated with radiotherapy plus cisplatin. Whether replacement of cisplatin with cetuximab-an antibody against the epidermal growth factor receptor-can preserve high survival and reduce treatment toxicity is unknown. We investigated whether cetuximab would maintain a high proportion of patient survival and reduce acute and late toxicity.<h4>Methods</h4>RTOG 1016 was a ...[more]

Project description:BackgroundNo risk-stratification strategies exist for patients with recurrent oropharyngeal cancer (OPC).MethodsRetrospective analysis using data from prospective NRG Oncology clinical trials RTOG 0129 and 0522. Eligibility criteria included known p16 status and smoking history, and locoregional/distant recurrence. Overall survival (OS) was measured from date of recurrence. Recursive partitioning analysis was performed to produce mutually exclusive risk groups.ResultsHundred and fifty-four patients were included with median follow-up after recurrence of 3.9 years (range 0.04-9.0). The most important factors influencing survival were p16 status and type of recurrence, followed by surgical salvage and smoking history (≤20 vs. >20 pack-years). Three significantly different risk groups were identified. Patients in the low-, intermediate-, and high-risk groups had 2-year OS after recurrence of 81.1% (95%CI 68.5-93.7), 50.2% (95%CI 36.0-64.5), and 20.8% (95%CI 10.5-31.1), respectively.ConclusionPatient and tumor characteristics may be used to stratify patients into risk groups at the time of OPC recurrence.

Project description:ImportanceThe role of epidermal growth factor receptor (EGFR) inhibition in chemoradiation strategies in the nonoperative treatment of patients with esophageal cancer remains uncertain.ObjectiveTo evaluate the benefit of cetuximab added to concurrent chemoradiation therapy for patients undergoing nonoperative treatment of esophageal carcinoma.Design, setting, and participantsA National Cancer Institute (NCI) sponsored, multicenter, phase 3, randomized clinical trial open to patients with biopsy-proven carcinoma of the esophagus. The study accrued 344 patients from 2008 to 2013.InterventionsPatients were randomized to weekly concurrent cisplatin (50 mg/m2), paclitaxel (25 mg/m2), and daily radiation of 50.4 Gy/1.8 Gy fractions with or without weekly cetuximab (400 mg/m2 on day 1 then 250 mg/m2 weekly).Main outcomes and measuresOverall survival (OS) was the primary endpoint, with a study designed to detect an increase in 2-year OS from 41% to 53%; 80% power and 1-sided α = .025.ResultsBetween June 30, 2008, and February 8, 2013, 344 patients were enrolled. This analysis used all data received at NRG Oncology through April 12, 2015. Sixteen patients were ineligible, resulting in 328 evaluable patients, 159 in the experimental arm and 169 in the control arm. Patients were well matched between the treatment arms for patient and tumor characteristics: 263 (80%) with T3 or T4 disease, 215 (66%) N1, and 62 (19%) with celiac nodal involvement. Incidence of grade 3, 4, or 5 treatment-related adverse events at any time was 71 (46%), 35 (23%), or 6 (4%) in the experimental arm and 83 (50%), 28 (17%), or 2 (1%) in the control arm, respectively. A clinical complete response (cCR) rate of 81 (56%) was observed in the experimental arm vs 92 (58%) in the control arm (Fisher exact test, P = .66). No differences were seen in cCR between treatment arms for either histology (adenocarcinoma or squamous cell). Median follow-up for all patients was 18.6 months. The 24- and 36-month local failure for the experimental arm was 47% (95% CI, 38%-57%) and 49% (95% CI, 40%-59%) vs 49% (95% CI, 41%-58%) and 49% (95% CI, 41%-58%) for the control arm (HR, 0.92; 95% CI, 0.66-1.28; P = .65). The 24- and 36-month OS rates for the experimental arm were 45% (95% CI, 37%-53%) and 34% (95% CI, 26%-41%) vs 44% (95% CI, 36%-51%) and 28% (95% CI, 21%-35%) for the control arm (HR, 0.90; 95% CI, 0.70-1.16; P = .47).Conclusions and relevanceThe addition of cetuximab to concurrent chemoradiation did not improve OS. These phase 3 trial results point to little benefit to current EGFR-targeted agents in an unselected patient population, and highlight the need for predictive biomarkers in the treatment of esophageal cancer.Trial registrationclinicaltrials.gov Identifier: NCT00655876.

Project description:Purpose/objectivesNRG/RTOG 0436 evaluated cetuximab added to chemoradiation (CRT) for non-operative esophageal cancer management. PRO objectives assessed improvement in the FACT-Esophageal cancer subscale (ECS), version 4, with cetuximab, and if improved ECS correlated with clinical complete response (cCR).Materials/methodsPatients were randomized to cisplatin/paclitaxel/radiation ± cetuximab. Overall survival (OS) was the primary endpoint, with a 420 patient target, which also provided 82% power to detect ≥ 15 increase in the proportion of cetuximab patients with ECS improvement from baseline to 6-8 weeks post-CRT; α = 0.05, using a χ2 test. Improvement in ECS and its Swallowing and Eating Indices (SI, EI) was defined as 5, 4 and 2 point increases, respectively, from baseline to 6-8 weeks post-CRT. Univariate logistic regression assessed if cCR was associated with improved ECS.ResultsThis study was stopped early for not meeting a pre-specified OS endpoint and did not show survival benefit. Of 420 planned patients, 344 enrolled and 281 consented to PROs. ECS was completed by 261 (93%) at baseline, 173 (66%) 6-8 weeks post-CRT, and 117 (64%) at 1 year. At 6-8 weeks, patients receiving CRT + Cetuximab didn't have improved ECS; they experienced a lower proportion of improvement compared to standard CRT (37% vs. 53%; P = 0.04). The proportion of CRT patients with improvement in SI was 9% higher than with cetuximab, but not statistically significant (39% vs. 30%, P = 0.22). There was no association between treatment and EI. When examining ECS scores at 1 year by cCR vs. residual disease, a higher proportion of cCR patients improved, but not statistically significant (48% vs. 45%, P = 0.74).ConclusionsThe addition of cetuximab to CRT for the nonoperative management of esophageal cancer did not improve PROs.

Project description:BackgroundThree- and five-year progression-free survival (PFS) for low-risk meningioma managed with surgery and observation reportedly exceeds 90%. Herewith we summarize outcomes for low-risk meningioma patients enrolled on NRG/RTOG 0539.MethodsThis phase II trial allocated patients to one of three groups per World Health Organization grade, recurrence status, and resection extent. Low-risk patients had either gross total (GTR) or subtotal resection (STR) for a newly diagnosed grade 1 meningioma and were observed after surgery. The primary endpoint was 3-year PFS. Adverse events (AEs) were scored using Common Terminology Criteria for Adverse Events (CTCAE) version 3.ResultsAmong 60 evaluable patients, the median follow-up was 9.1 years. The 3-, 5-, and 10-year rates were 91.4% (95% CI, 84.2 to 98.6), 89.4% (95% CI, 81.3 to 97.5), 85.0% (95% CI, 75.3 to 94.7) for PFS and 98.3% (95% CI, 94.9 to 100), 98.3%, (95% CI, 94.9 to 100), 93.8% (95% CI, 87.0 to 100) for overall survival (OS), respectively. With centrally confirmed GTR, 3/5/10y PFS and OS rates were 94.3/94.3/87.6% and 97.1/97.1/90.4%. With STR, 3/5/10y PFS rates were 83.1/72.7/72.7% and 10y OS 100%. Five patients reported one grade 3, four grade 2, and five grade 1 AEs. There were no grade 4 or 5 AEs.ConclusionsThese results prospectively validate high PFS and OS for low-risk meningioma managed surgically but raise questions regarding optimal management following STR, a subcohort that could potentially benefit from adjuvant therapy.

Project description:OBJECTIVE This is the first clinical outcomes report of NRG Oncology RTOG 0539, detailing the primary endpoint, 3-year progression-free survival (PFS), compared with a predefined historical control for intermediate-risk meningioma, and secondarily evaluating overall survival (OS), local failure, and prospectively scored adverse events (AEs). METHODS NRG Oncology RTOG 0539 was a Phase II clinical trial allocating meningioma patients to 1 of 3 prognostic groups and management strategies according to WHO grade, recurrence status, and resection extent. For the intermediate-risk group (Group 2), eligible patients had either newly diagnosed WHO Grade II meningioma that had been treated with gross-total resection (GTR; Simpson Grades I-III) or recurrent WHO Grade I meningioma with any resection extent. Pathology and imaging were centrally reviewed. Patients were treated with radiation therapy (RT), either intensity modulated (IMRT) or 3D conformal (3DCRT), 54 Gy in 30 fractions. The RT target volume was defined as the tumor bed and any nodular enhancement (e.g., in patients with recurrent WHO Grade I tumors) with a minimum 8-mm and maximum 15-mm margin, depending on tumor location and setup reproducibility of the RT method. The primary endpoint was 3-year PFS. Results were compared with historical controls (3-year PFS: 70% following GTR alone and 90% with GTR + RT). AEs were scored using NCI Common Toxicity Criteria. RESULTS Fifty-six patients enrolled in the intermediate-risk group, of whom 3 were ineligible and 1 did not receive RT. Of the 52 patients who received protocol therapy, 4 withdrew without a recurrence before 3 years leaving 48 patients evaluable for the primary endpoint, 3-year PFS, which was actuarially 93.8% (p = 0.0003). Within 3 years, 3 patients experienced events affecting PFS: 1 patient with a WHO Grade II tumor died of the disease, 1 patient with a WHO Grade II tumor had disease progression but remained alive, and 1 patient with recurrent WHO Grade I meningioma died of undetermined cause without tumor progression. The 3-year actuarial local failure rate was 4.1%, and the 3-year OS rate was 96%. After 3 years, progression occurred in 2 additional patients: 1 patient with recurrent WHO Grade I meningioma and 1 patient with WHO Grade II disease; both remain alive. Among 52 evaluable patients who received protocol treatment, 36 (69.2%) had WHO Grade II tumors and underwent GTR, and 16 (30.8%) had recurrent WHO Grade I tumors. There was no significant difference in PFS between these subgroups (p = 0.52, HR 0.56, 95% CI 0.09-3.35), validating their consolidation. Of the 52 evaluable patients, 44 (84.6%) received IMRT, and 50 (96.2%) were treated per protocol or with acceptable variation. AEs (definitely, probably, or possibly related to protocol treatment) were limited to Grade 1 or 2, with no reported Grade 3 events. CONCLUSIONS This is the first clinical outcomes report from NRG Oncology RTOG 0539. Patients with intermediate-risk meningioma treated with RT had excellent 3-year PFS, with a low rate of local failure and a low risk of AEs. These results support the use of postoperative RT for newly diagnosed gross-totally resected WHO Grade II or recurrent WHO Grade I meningioma irrespective of resection extent. They also document minimal toxicity and high rates of tumor control with IMRT. Clinical trial registration no.: NCT00895622 (clinicaltrials.gov).

Project description:BackgroundPhase 2 cooperative group meningioma trial assessing the safety and efficacy of risk-adaptive management strategies. This is the initial analysis of the high-risk cohort.Methods and materialsHigh-risk patients were those with a new or recurrent World Health Organization (WHO) grade III meningioma of any resection extent, recurrent WHO grade II of any resection extent, or new WHO grade II after subtotal resection. Patients received intensity-modulated radiotherapy (IMRT) using a simultaneous integrated boost technique (60 Gy high dose and 54 Gy low dose in 30 fractions). Three-year progression-free survival (PFS) was the primary endpoint. Adverse events (AEs) were scored per NCI Common Terminology Criteria for Adverse Events version 3.ResultsOf 57 enrolled patients, 53 received protocol treatment. Median follow-up was 4.0 years (4.8 years for living patients). Two patients withdrew without progression before year 3; for the remaining 51 patients, 3-year PFS was 58.8%. Among all 53 protocol-treated patients, 3-year PFS was 59.2%. Three-year local control was 68.9%, and overall survival was 78.6%. Of 51 patients, 1 patient (1.9%) experienced a late grade-5 necrosis-related AE. All other acute (23 of 53 patients) and late (21 of 51 patients) AEs were grades 1 to 3.ConclusionsPatients with high-risk meningioma treated with IMRT (60 Gy/30) experienced 3-year PFS of 58.8%. Combined acute and late AEs were limited to grades 1 to 3, except for a single necrosis-related grade 5 event. These results support postoperative IMRT for high-risk meningioma and invite ongoing investigations to improve outcomes further.

Project description:BackgroundTrastuzumab is a monoclonal antibody against HER2 (also known as ERBB2). The primary objective of the NRG Oncology/RTOG-1010 trial was to establish whether trastuzumab improves disease-free survival when combined with trimodality treatment (paclitaxel plus carboplatin and radiotherapy, followed by surgery) for patients with untreated HER2-overexpressing oesophageal adenocarcinoma.MethodsNRG Oncology/RTOG-1010 was an open label, randomised, phase 3 trial for which patients were accrued from 111 NRG-affiliated institutions in the USA. Eligible patients were adults (aged ≥18 years) with newly diagnosed pathologically confirmed oesophageal adenocarcinoma, American Joint Committee on Cancer 7th edition T1N1-2 or T2-3N0-2 stage disease, and a Zubrod performance status of 0-2. Patients were stratified by adenopathy (no vs yes [coeliac absent] vs yes [coeliac present ≤2 cm]) and randomly assigned (1:1) to receive weekly intravenous paclitaxel (50 mg/m2 intravenously over 1 h) and carboplatin (area under the curve 2, intravenously over 30-60 min) for 6 weeks with radiotherapy 50·4 Gy in 28 fractions (chemoradiotherapy) followed by surgery, with or without intravenous trastuzumab (4 mg/kg in week one, 2 mg/kg per week for 5 weeks during chemoradiotherapy, 6 mg/kg once presurgery, and 6 mg/kg every 3 weeks for 13 treatments starting 21-56 days after surgery). The primary endpoint, disease-free survival, was defined as the time from randomisation to death or first of locoregional disease persistence or recurrence, distant metastases, or second primary malignancy. Analyses were done by modified intention to treat. This study is registered with Clinicaltrials.gov, NCT01196390; it is now closed and in follow-up.Findings606 patients were entered for HER2 assessment from Dec 30, 2010 to Nov 10, 2015, and 203 eligible patients who were HER2-positive were enrolled and randomly assigned to chemoradiotherapy plus trastuzumab (n=102) or chemoradiotherapy alone (n=101). Median duration of follow-up was 2·8 years (IQR 1·4-5·7). Median disease-free survival was 19·6 months (95% CI 13·5-26·2) with chemoradiotherapy plus trastuzumab compared with 14·2 months (10·5-23·0) for chemoradiotherapy alone (hazard ratio 0·99 [95% CI 0·71-1·39], log-rank p=0·97). Grade 3 treatment-related adverse events occurred in 41 (43%) of 95 patients in the chemoradiotherapy plus trastuzumab group versus 52 (54%) of 96 in the chemoradiotherapy group and grade 4 events occurred in 20 (21%) versus 21 (22%). The most common grade 3 or worse treatment-related adverse events for both groups were haematological (53 [56%] of 95 patients in the chemoradiotherapy plus trastuzumab group vs 55 [57%] of 96 patients in the chemotherapy group) or gastrointestinal disorders (28 [29%] vs 20 [21 %]). 34 (36%) of 95 patients in the chemoradiotherapy plus trastuzumab group and 27 (28%) of 96 patients in the chemoradiotherapy only group had treatment-related serious adverse events. There were eight treatment-related deaths: five (5%) of 95 patients in the chemoradiotherapy plus trastuzumab group (bronchopleural fistula, oesophageal anastomotic leak, lung infection, sudden death, and death not otherwise specified), and three (3%) of 96 in the chemoradiotherapy group (two multiorgan failure and one sepsis).InterpretationThe addition of trastuzumab to neoadjuvant chemoradiotherapy for HER2-overexpressing oesophageal cancer was not effective. Trastuzumab did not lead to increased toxicities, suggesting that future studies combining it with or using other agents targeting HER2 in oesophageal cancer are warranted.FundingNational Cancer Institute and Genentech.

Project description:PurposeNRG/RTOG 0841 assessed the feasibility of a depression screening procedure in patients receiving radiation therapy (RT). As a secondary endpoint, availability and barriers to psychosocial care data were collected in hopes of providing recommendations for improved psychosocial care among patients receiving RT.Methods and materialsPatients starting RT were prospectively recruited and assessed with self-reported distress screening tools. Patients exceeding a validated cutoff and a sample of patients who screened negative received the Structured Clinical Interview for DSM-IV (SCID) mood disorder modules via telephone. During that SCID evaluation, patients completed a validated scale ranking interview on barriers to psychosocial care and interest in various psychosocial intervention modalities.ResultsA total of 463 patients from 35 community-based and 2 academic RT oncology sites were recruited. Of the 455 eligible, 75 (16%) exceeded screening cutoffs for depressive symptoms. From this group, 78 patients completed the SCID; most were female (76%), white (88%), and had breast cancer (55%). Overall, the most common barriers to treatment, regardless of insurance, were costs (58%), daily responsibilities (44%), and physical health symptoms (38%). Patients from RT facilities without mental health services were significantly more likely to report difficulty with physical health problems, specifically serious illness and walking, compared with those treated at RT facilities with services (P = .013 and P = .039, respectively). Overall, there was interest in obtaining psychosocial services with face-to-face counseling at the cancer center and printed educational materials as the most commonly preferred interventions. Patients with difficult barriers to psychosocial interventions were significantly less interested in support away from the cancer center (P = .016), telephone and Internet counseling (P = .0062 &P = .011), and Internet support (P = .0048).ConclusionRadiation oncology patients are interested in obtaining psychosocial services but face barriers to access to mental health services including cost, debilitating symptoms, and time constraints that prevent adequate care.

Project description:Purpose NRG Oncology/RTOG 1203 was designed to compare patient-reported acute toxicity and health-related quality of life during treatment with standard pelvic radiation or intensity-modulated radiation therapy (IMRT) in women with cervical and endometrial cancer. Methods Patients were randomly assigned to standard four-field radiation therapy (RT) or IMRT radiation treatment. The primary end point was change in patient-reported acute GI toxicity from baseline to the end of RT, measured with the bowel domain of the Expanded Prostate Cancer Index Composite (EPIC). Secondary end points included change in patient-reported urinary toxicity, change in GI toxicity measured with the Patient-Reported Outcome Common Terminology Criteria for Adverse Events, and quality of life measured with the Trial Outcome Index. Results From 2012 to 2015, 289 patients were enrolled, of whom 278 were eligible. Between baseline and end of RT, the mean EPIC bowel score declined 23.6 points in the standard RT group and 18.6 points in the IMRT group ( P = .048), the mean EPIC urinary score declined 10.4 points in the standard RT group and 5.6 points in the IMRT group ( P = .03), and the mean Trial Outcome Index score declined 12.8 points in the standard RT group and 8.8 points in the IMRT group ( P = .06). At the end of RT, 51.9% of women who received standard RT and 33.7% who received IMRT reported frequent or almost constant diarrhea ( P = .01), and more patients who received standard RT were taking antidiarrheal medications four or more times daily (20.4% v 7.8%; P = .04). Conclusion Pelvic IMRT was associated with significantly less GI and urinary toxicity than standard RT from the patient's perspective.
