Successes and lessons learned in database development for national multi-site cancer care delivery research trials: the Alliance for Clinical Trials in Oncology experience.

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.

Rates of Guideline-Concordant Surgery and Adjuvant Chemotherapy Among Patients With Early-Stage Lung Cancer in the US ALCHEMIST Study (Alliance A151216).

Importance: Standard treatment for resectable non-small cell lung cancer (NSCLC) includes anatomic resection with adequate lymph node dissection and adjuvant chemotherapy for appropriate patients. Historically, many patients with early-stage NSCLC have not received such treatment, which may affect the interpretation of the results of adjuvant therapy trials. Objective: To ascertain patterns of guideline-concordant treatment among patients enrolled in a US-wide screening protocol for adjuvant treatment trials for resected NSCLC. Design, Setting, and Participants: This retrospective cohort study included 2833 patients with stage IB to IIIA NSCLC (per American Joint Committee on Cancer 7th edition criteria) who enrolled in the Adjuvant Lung Cancer Enrichment Marker Identification and Sequencing Trial (ALCHEMIST) screening study (Alliance for Clinical Trials in Oncology A151216) from August 18, 2014, to April 1, 2019, and who did not enroll in a therapeutic adjuvant clinical trial; patients had tumors of at least 4 cm and/or with positive lymph nodes. Statistical analysis was conducted from June 1, 2020, through October 1, 2021. Exposures: Care patterns were ascertained overall and by sociodemographic and clinical factors, including age, sex, race and ethnicity, educational level, marital status, geography, histologic characteristics, stage, genomic variant status, smoking history, and comorbidities. Main Outcomes and Measures: Five outcomes are reported: whether patients (1) had anatomic surgical resection, (2) had adequate lymph node dissection (≥1 N1 nodal station plus ≥3 N2 nodal stations), (3) received any adjuvant chemotherapy, (4) received any cisplatin-based adjuvant chemotherapy, and (5) received at least 4 cycles of adjuvant chemotherapy. Results: Of the 2833 patients (1505 women [53%]; mean [SD] age, 66.5 [9.2] years) included in this analysis, 2697 (95%) had anatomic surgical resection, 1513 (53%) had adequate lymph node dissection, 1617 (57%) received any adjuvant chemotherapy, 1237 (44%) received at least 4 cycles of adjuvant platinum-based chemotherapy, and 965 (34%) received any cisplatin-based adjuvant chemotherapy. Rates were similar across race and ethnicity. Conclusions and Relevance: This cohort study found that among participants in a screening protocol for adjuvant clinical trials for resected early-stage NSCLC, just 53% underwent adequate lymph node dissection, and 57% received adjuvant chemotherapy, despite indications for such treatment. These results may affect the interpretation of adjuvant trials. Efforts are needed to optimize the use of proven therapies for early-stage NSCLC.

Patient-reported quality-of-life outcomes in relation to provider-assessed adverse events during head and neck radiotherapy.

PURPOSE: To assess the relationship between patient-reported quality-of-life (QOL) outcomes and provider-assessed adverse events (AEs) during head-and-neck (H&N) radiotherapy (RT). METHODS: Sixty-five patients undergoing H&N RT prospectively completed 12-domain linear analogue self-assessments (LASA) at baseline, before biweekly appointments, and at last week of RT. At the same time points, provider-assessed AEs were graded using Common Terminology Criteria for Adverse Events v4.0. LASA scores were stratified by maximum-grade AE and analyzed using Kruskal-Wallis methodology. Agreement between LASA scores and maximum-grade AE was assessed using Bland-Altman analysis. RESULTS: Patient-reported QOL outcomes showed clinically meaningful decreases in most domains, predominantly fatigue (77.8% of patients), social activity (75.4%), and overall QOL (74.2%). Provider-assessed AEs showed 100% grade 2 AE, 35.4% grade 3 AE, and 3.1% grade 4 AE. At baseline, patients with higher grade AEs reported worse physical well-being (WB) (P = .04). At week 1, the following QOL domains were worse for patients with higher grade AEs: overall QOL (P = .03), mental WB (P = .02), and physical WB (P = .03). Bland-Altman analysis showed that QOL scores were relatively worse than AE burden at baseline and relatively better at RT completion. CONCLUSIONS: Worse QOL was associated with higher-grade AEs at baseline and early in RT. The impact of AEs on QOL appears to lessen with time. Patient-reported QOL outcomes and provider-assessed AEs provide complementary information.

A phase I study of the VEGFR kinase inhibitor vatalanib in combination with the mTOR inhibitor, everolimus, in patients with advanced solid tumors.

Purpose Combining small-molecule inhibitors of different targets was shown to be synergistic in preclinical studies. Testing this concept in clinical trials is, however, daunting due to challenges in toxicity management and efficacy assessment. This study attempted to evaluate the safety and efficacy of vatalanib plus everolimus in patients with advanced solid tumors and explore the utility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) studies as a predictive biomarker. Patients and Methods This single-center, phase I trial containing 70 evaluable patients consisted of a dose escalation proportion based on the traditional "3 + 3" design (cohort IA and IB) and a dose expansion proportion (cohort IIA and IIB). Toxicity was evaluated using the Common Terminology Criteria of Adverse Events. Antitumor activity was assessed using the Modified Response Evaluation Criteria in Solid Tumors. Results The maximum tolerated doses were determined to be vatalanib 1250 mg once daily or 750 mg twice daily in combination with everolimus 10 mg once daily. No treatment-related death occurred. The most common toxicities were hypertriglyceridemia, hypercholesterolemia, fatigue, vomiting, nausea and diarrhea. There was no complete response. Nine patients (12.9%) had partial response (PR) and 41 (58.6%) had stable disease (SD). Significant antitumor activity was observed in neuroendocrine tumors with a disease-control rate (PR + SD) of 66.7% and other tumor types including renal cancer, melanoma, and non-small-cell lung cancer. Conclusions The combination of vatalanib and everolimus demonstrated reasonable toxicity and clinical activity. Future studies combining targeted therapies and incorporating biomarker analysis are warranted based on this phase I trial.

A Phase II Study of Pazopanib in Patients with Malignant Pleural Mesothelioma: NCCTG N0623 (Alliance).

PURPOSE: Preclinical and clinical data have shown promise in using antiangiogenic agents to treat malignant pleural mesothelioma (MPM). We conducted this phase II study to evaluate the efficacy and toxicity of single-agent pazopanib in patients with MPM. MATERIALS AND METHODS: Patients with MPM who had received 0-1 prior chemotherapy regimens were eligible to receive pazopanib at a dose of 800 mg daily. The primary endpoint was progression-free survival rate at 6 months (PFS6), with a preplanned interim analysis for futility. Secondary endpoints included overall survival (OS), PFS, adverse events assessment and clinical benefit (complete response, partial response [PR], and stable disease [SD]). RESULTS: Thirty-four evaluable patients were enrolled, with a median age of 73 years (49-84). The trial was closed early because of lack of efficacy at the preplanned interim analysis. Only 8 patients (28.6%; 95% confidence interval [CI], 13.2-48.7%) in the first 28 evaluable were progression-free at 6 months. PFS6 was 32.4% (95% CI, 17.4-50.5). There were 2 PR (5.9%) and 16 SD (47.1%). The overall median PFS and OS were 4.2 months (95% CI, 2.0-6.0) and 11.5 months (95% CI: 5.3-18.2), respectively. The median PFS and OS for the previously untreated patients was 5.4 months (95% CI, 2.7-8.5) and 16.6 months (95% CI, 6.6-30.6), respectively; and 2.0 months (95% CI, 1.3-4.2) and 5.0 months (95% CI: 3.0-11.9), respectively, for the previously treated patients. Grade 3 or higher adverse events were observed in 23 patients (67.6%). CONCLUSION: Single-agent pazopanib was poorly tolerated in patients with MPM. The primary endpoint of PFS6 was not achieved in the current study. ClinicalTrials.gov identification number. NCT00459862. IMPLICATIONS FOR PRACTICE: Single-agent pazopanib did not meet its endpoint in this phase II trial in malignant mesothelioma. Pazopanib is well tolerated in mesothelioma patients with a manageable toxicity profile. There is a need to better identify signals of angiogenesis that can be targeted in mesothelioma. Encouraging findings in frontline treatment warrant further investigations in combination with chemotherapy or immunotherapy.

A Randomized Double-Blind Phase II Study of the Seneca Valley Virus (NTX-010) versus Placebo for Patients with Extensive-Stage SCLC (ES SCLC) Who Were Stable or Responding after at Least Four Cycles of Platinum-Based Chemotherapy: North Central Cancer Treatment Group (Alliance) N0923 Study.

INTRODUCTION: The Seneca Valley virus (NTX-010) is an oncolytic picornavirus with tropism for SCLC. This phase II double-blind, placebo-controlled trial evaluated NTX-010 in patients with extensive-stage (ES) SCLC after completion of first-line chemotherapy. METHODS: Patients with ES SCLC who did not progress after four or more cycles of platinum-based chemotherapy were randomized 1:1 to a single dose of NTX-010 or placebo within 12 weeks of chemotherapy. The primary end point was progression-free survival (PFS). A prespecified interim analysis for futility was performed after 40 events. Viral clearance and the development of neutralizing antibodies were followed. RESULTS: From January 15, 2010, to January 10, 2013, a total of 50 patients were randomized and received therapy on study (26 received NTX-010 and 24 received placebo). At the specified interim analysis, the median PFS was 1.7 months (95% confidence interval [CI]: 1.4-3.1 months) for the NTX-010 group versus 1.7 months (95% CI: 1.4-4.3 months) for the placebo group (hazard ratio = 1.03, p = 0.92), and the trial was terminated owing to futility. In the NTX-010 group, PFS was shorter in patients with detectable virus at days 7 and 14 versus in those in whom it was not detected after treatment (1.0 month [95% CI: 0.4-1.5 months] versus 1.8 months [95% CI: 1.3-5.5 months, p = 0.008] and 0.9 months [95% CI: 0.4-2.6 months] versus 1.3 months [95% CI: 1.0-5.3 months], respectively [p = 0.04]). CONCLUSIONS: Patients with ES SCLC did not benefit from NTX-010 treatment after chemotherapy with a platinum doublet. Persistence of NTX-010 in the blood 1 or 2 weeks after treatment was associated with a shorter PFS.

Randomized controlled trial of cryotherapy to prevent paclitaxel-induced peripheral neuropathy (RU221511I); an ACCRU trial.

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 15 min prior to and ending 15 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, p = 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 p = 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.

A Case Management System for Integrating Patient-reported Outcome Assessment in Clinical Practice: The Beacon Tool.

INTRODUCTION: What if you could only ask one question of the patient during a clinic visit? Further, suppose the patient's biggest concern can pragmatically be incorporated into routine clinical care and clinical pathways that can address the patient's single biggest concern can be identified. If the principal concern can be dealt with efficiently at each visit through key stakeholder case management, positive outcomes should result. Therefore, motivated by the need for patient-centered health care visits, the Beacon electronic patient-reported outcomes (PRO) quality of life (QOL) tool was developed. METHODS: Central to the tool is that at each health care visit, the patient's biggest concern is electronically communicated to the health care team. Therefore, the tool can help catalyze important discussions between the health care team and the patient, perhaps on topics that would not have been discussed otherwise at a routine visit. In recognition of the community of resources needed to provide comprehensive care, the tool generates clinical pathways or actions that can be pursued to address the patient's biggest concern. The concern is efficiently triaged such that members of the health care community with appropriate expertise and resources are identified to address and manage that single biggest concern signaled by the patient. A report, which can be uploaded into the patient's medical chart, is created and provides a list of resources for a case manager to assist the patient and contains graphical presentations of the patient's QOL and a history of prior concerns. The report also labels potentially significant changes in QOL. DISCUSSION: The tool, which has been applied successfully in several health conditions, acts as a beacon to health care providers so that a patient's self-reported concern can be consistently and effectively integrated into their care. KEY POINTS: It is impractical to try to deal with every patient concern in every visit. The key to the Beacon tool is that at each visit the patient's biggest concern is identified, clinical pathways indicated, and resources efficiently matched to address the patient's biggest concern.

Effect of Doxepin Mouthwash or Diphenhydramine-Lidocaine-Antacid Mouthwash vs Placebo on Radiotherapy-Related Oral Mucositis Pain: The Alliance A221304 Randomized Clinical Trial.

Importance: Oral mucositis causes substantial morbidity during head and neck radiotherapy. In a randomized study, doxepin mouthwash was shown to reduce oral mucositis-related pain. A common mouthwash comprising diphenhydramine-lidocaine-antacid is also widely used. Objective: To evaluate the effect of doxepin mouthwash or diphenhydramine-lidocaine-antacid mouthwash for the treatment of oral mucositis-related pain. Design, Setting, and Participants: A phase 3 randomized trial was conducted from November 1, 2014, to May 16, 2016, at 30 US institutions and included 275 patients who underwent definitive head and neck radiotherapy, had an oral mucositis pain score of 4 points or greater (scale, 0-10), and were followed up for a maximum of 28 days. Interventions: Ninety-two patients were randomized to doxepin mouthwash (25 mg/5 mL water); 91 patients to diphenhydramine-lidocaine-antacid; and 92 patients to placebo. Main Outcome and Measures: The primary end point was total oral mucositis pain reduction (defined by the area under the curve and adjusted for baseline pain score) during the 4 hours after a single dose of doxepin mouthwash or diphenhydramine-lidocaine-antacid mouthwash compared with a single dose of placebo. The minimal clinically important difference was a 3.5-point change. The secondary end points included drowsiness, unpleasant taste, and stinging or burning. All scales ranged from 0 (best) to 10 (worst). Results: Among the 275 patients randomized (median age, 61 years; 58 [21%] women), 227 (83%) completed treatment per protocol. Mucositis pain during the first 4 hours decreased by 11.6 points in the doxepin mouthwash group, by 11.7 points in the diphenhydramine-lidocaine-antacid mouthwash group, and by 8.7 points in the placebo group. The between-group difference was 2.9 points (95% CI, 0.2-6.0; P = .02) for doxepin mouthwash vs placebo and 3.0 points (95% CI, 0.1-5.9; P = .004) for diphenhydramine-lidocaine-antacid mouthwash vs placebo. More drowsiness was reported with doxepin mouthwash vs placebo (by 1.5 points [95% CI, 0-4.0]; P = .03), unpleasant taste (by 1.5 points [95% CI, 0-3.0]; P = .002), and stinging or burning (by 4.0 points [95% CI, 2.5-5.0]; P < .001). Maximum grade 3 adverse events for the doxepin mouthwash occurred in 3 patients (4%); diphenhydramine-lidocaine-antacid mouthwash, 3 (4%); and placebo, 2 (2%). Fatigue was reported by 5 patients (6%) in the doxepin mouthwash group and no patients in the diphenhydramine-lidocaine-antacid mouthwash group. Conclusions and Relevance: Among patients undergoing head and neck radiotherapy, the use of doxepin mouthwash or diphenhydramine-lidocaine-antacid mouthwash vs placebo significantly reduced oral mucositis pain during the first 4 hours after administration; however, the effect size was less than the minimal clinically important difference. Further research is needed to assess longer-term efficacy and safety for both mouthwashes. Trial Registration: ClinicalTrials.gov Identifier: NCT02229539.

Impact of hospital hospitality house programs on quality of life and mood of patients and caregivers after hematopoietic stem cell transplant.

OBJECTIVE/BACKGROUND: The quality of life (QOL) of hematopoietic stem cell transplant (HSCT) patients and their caregivers decreases during the first 8 days after HSCT. METHODS: This prospective pilot study collected preliminary data on the impact of posttransplant living arrangements (hospital hospitality house [HHH] vs. hotel, apartment, or house ["hotel"]) and other factors on the QOL of HSCT patients and their caregivers. The predefined primary end point was QOL of patients and their caregivers on Day 30 (QOL30) as measured by the linear analog self-assessment (LASA). RESULTS: Forty-four HSCT patients participated (HHH 23, hotel 21; allogeneic 18, autologous 26). No significant differences in QOL30 (mean LASA score) were noted between patient groups (55.6 [HHH] vs. 72.2 [hotel], p = .06) or between caregiver groups (77.8 [HHH] vs. 88.9 [hotel], p = .20). Multivariate analysis for QOL30 showed that baseline QOL (p = .006) and age (p = .049) were significant predictors of QOL30 after adjustment for sex, post-HSCT living place, and transplant type. Older patients (≥60 years) had a significantly lower QOL30 than younger patients (mean score, 51.6 vs. 75.3; p = .02). CONCLUSION: Efforts to improve QOL30 of HSCT patients and caregivers in the confined environment of an HHH should focus on patients with low baseline QOL and older patients.

Electronic patient-reported outcomes and toxicities during radiotherapy for head-and-neck cancer.

PURPOSE: To characterize quality of life (QOL) using real-time, electronic patient-reported outcomes (ePROs) and to evaluate adverse events (AEs) and supportive care during head-and-neck radiotherapy (RT) and concurrent chemoradiotherapy (CCRT). METHODS: Sixty-five patients undergoing head-and-neck RT completed electronic, real-time, 12-item linear analog self-assessments (LASA) at baseline, before biweekly appointments, and at the last week of RT. Changes in QOL domains between time points were calculated. Clinical data were collected from the institutional medical record. AEs were recorded at the same time points as the LASA and graded. RESULTS: During head-and-neck RT, most patients had clinically meaningful decreases in all QOL domains except level of support, financial concerns, and legal concerns. QOL domains with the most prevalent, clinically meaningful decreases were fatigue (75.4% of patients; 95% CI, 62.9-84.9%), social activity (70.8%; 95% CI, 58.0-81.1%), and overall QOL (70.8%; 95% CI, 58.0-81.1%). All patients had grade 2 AEs; 35.4% had grade 3 (50.0%, CCRT; 12.0%, RT; P = .002). Weight loss averaged 5.5 kg (6.9 kg, CCRT; 2.8 kg, RT; P < .001). Intravenous hydration was needed in 52.3% (77.5%, CCRT; 12.0%, RT; P < .001); feeding tube placement 40.0% (57.5%, CCRT; 12.0%, RT; P = .001); emergency department visits without hospitalization, 10.8%; and emergent hospitalization, 27.7% (37.5%, CCRT; 12.0%, RT; P = .04). CONCLUSIONS: Head-and-neck RT, particularly CCRT, negatively impacts patients' overall QOL, social activity, and fatigue, with frequent grade 3 AEs, weight loss, intravenous hydration, feeding tube placement, ED visits, and hospitalization. Real-time ePROs allow providers to monitor QOL at multiple time points during RT, potentially allowing early intervention to improve QOL and mitigate AEs.

Long-Term Results of a Trial of Concurrent Chemotherapy and Escalating Doses of Radiation for Unresectable Non-Small Cell Lung Cancer: NCCTG N0028 (Alliance).

INTRODUCTION: This phase I/II trial was designed to determine the maximally tolerated dose of thoracic radiotherapy as part of a combined modality approach. This report includes the long-term outcomes of patients treated on this study. The phase II portion was never completed, as RTOG-0617 opened before it was concluded. METHODS: In this study, the maximally tolerated dose was defined as 74 Gy of radiation in 37 fractions. Twenty-five patients with unresectable NSCLC were treated with 2-Gy daily fractions and concurrent weekly carboplatin and paclitaxel. Of these patients, 20 had stage III disease and five had stage I or II disease. RESULTS: Patients were followed until death or for a minimum of 5 years in the case of survivors. The median and 5-year survivals were 42.5 months and 20% for all patients, 52.9 months and 40% in patients with stages I or II disease, and 39.8 months and 15% in patients with stage III disease. CONCLUSIONS: The median survival of the stage III patients was quite favorable. We believe that this may have been due to a robust central review program of radiotherapy plans before treatment, ensuring compliance with protocol guidelines along with very low exposure of the heart to radiotherapy. Further improvements in 5-year survival will likely require research on both systemic therapy and thoracic radiotherapy. Potential therapeutic modalities that may aid in these efforts include immunotherapy, targeted therapy, improved imaging, adaptive radiotherapy, simultaneous integrated boost techniques, novel dose fractionation regimens, and charged particle therapy.

Impact of Sublobar Resection on Pulmonary Function: Long-Term Results from American College of Surgeons Oncology Group Z4032 (Alliance).

BACKGROUND: Sublobar resection (SR) in high-risk operable patients may result in a long-term decrease in pulmonary function. We previously reported 3-month pulmonary function outcomes from a randomized phase III study of SR alone compared with SR with brachytherapy in patients with non-small cell lung cancer. We now report long-term pulmonary function after SR. METHODS: Pulmonary function was measured at baseline and at 3, 12, and 24 months. A decline of 10% or more from baseline in the percentage predicted forced expiratory volume of 1 percentage or in the diffusion capacity of the lung for carbon monoxide was considered clinically meaningful. The effect of study arm, tumor location, size, approach (video-assisted thoracoscopic surgery vs thoracotomy), and SR type (wedge vs segmentectomy) on pulmonary function was assessed using a Wilcoxon rank sum test. A generalized estimating equation model was used to assess the effect of each factor on longitudinal data, including all four time points. RESULTS: Complete pulmonary function data at all time points was available in 69 patients. No significant differences were observed in pulmonary function between SR and SR with brachytherapy, thus the study arms were combined for all analyses. A decline of 10% or more (p = 0.02) in the percentage predicted forced expiratory volume in 1 second was demonstrated for lower-lobe resections at 3 months but was not at 12 or 24 months. A decline of 10% or more (p = 0.05) in the percentage predicted diffusion capacity of the lung for carbon monoxide was seen for thoracotomy at 3 months but was not at 12 or 24 months. CONCLUSIONS: Clinically meaningful declines in pulmonary function occurred after lower lobe resection and after thoracotomy at 3 months but subsequently recovered. This study suggests that SR does not result in sustained decreased pulmonary function in high-risk operable patients.

A Nomogram to Predict Recurrence and Survival of High-Risk Patients Undergoing Sublobar Resection for Lung Cancer: An Analysis of a Multicenter Prospective Study (ACOSOG Z4032).

BACKGROUND: Individualized prediction of outcomes may help with therapy decisions for patients with non-small cell lung cancer. We developed a nomogram by analyzing 17 clinical factors and outcomes from a randomized study of sublobar resection for non-small cell lung cancer in high-risk operable patients. The study compared sublobar resection alone with sublobar resection with brachytherapy. There were no differences in primary and secondary outcomes between the study arms, and they were therefore combined for this analysis. METHODS: The clinical factors of interest (considered as continuous variables) were assessed in a univariate Cox proportional hazards model for significance at the 0.10 level for their impact on overall survival (OS), local recurrence-free survival (LRFS), and any recurrence-free survival (RFS). The final multivariable model was developed using a stepwise model selection. RESULTS: Of 212 patients, 173 had complete data on all 17 risk factors. Median follow-up was 4.94 years (range, 0.04 to 6.22). The 5-year OS, LRFS, and RFS were 58.4%, 53.2%, and 47.4%, respectively. Age, baseline percent diffusing capacity of lung for carbon monoxide, and maximum tumor diameter were significant predictors for OS, LRFS, and RFS in the multivariable model. Nomograms were subsequently developed for predicting 5-year OS, LRFS, and RFS. CONCLUSIONS: Age, baseline percent diffusing capacity of lung for carbon monoxide, and maximum tumor diameter significantly predicted outcomes after sublobar resection. Such nomograms may be helpful for treatment planning in early stage non-small cell lung cancer and to guide future studies.

Comparing and Validating Simple Measures of Patient-Reported Peripheral Neuropathy for Oncology Clinical Trials: NCCTG N0897 (Alliance) A Pooled Analysis of 2440 Patients.

INTRODUCTION: Current standard evaluation of Peripheral Neuropathy (PN) is based on an investigator-reported classification system that is commonly unable to correctly reflect the subjective symptoms for patients. Thus more reliable methods to assess PN are needed. This study assessed alternative methods of assessing patient-reported PN in 5 North Central Cancer Treatment Group (NCCTG) clinical trials. METHOD: Two single-item assessments relating to numbness and tingling were used to measure PN. Patients' Quality Of Life (QOL) was also assessed using the Uniscale, Symptom Distress Scale (SDS), Profile of Mood States (POMS), Brief Pain Inventory (BPI) and Subject Global Impression of Change (SGIC). Wilcoxon tests compared QOL scores between patients with PN (score > 50) vs. no PN (score ≤ 50). Changes from baseline in QOL were compared by Wilcoxon rank sum test with a 20-point change in PN defined as clinically meaningful. Both distribution-based and anchor-based approaches were used to derive estimates of Minimal Important Differences (MID). Standardized Response Means (SRM), Effect Sizes (ES) and Guyatt's responsiveness statistic were used to measure responsiveness. RESULTS: The proportion of patients reporting numbness (tingling) at baseline was 10.7% (10.0%) and 18.4% (17.8%) at last assessment. The correlation between numbness and tingling at baseline was 0.81, and at last assessment was 0.83. Patients with substantial PN reported an average of 10 points lower overall QOL, mood and worse symptom distress and 20 points lower in the BPI interference items. Patients having a ≤ 20 point worsening in PN score reported significantly worse in symptom distress and BPI worst pain, but not in POMS or overall QOL. The MID estimates were similar between numbness and tingling items but varied depending on the approach used. Responsiveness statistics indicated that the two PN assessments are sensitive and responsive instruments for cancer patients with PN. CONCLUSIONS: The two PN items for numbness and tingling were redundant. Evidence of criterion validity and responsiveness indicates that these simple measures of PN can be used successfully in cancer clinical trials.

A new scoring system for predicting survival in patients with non-small cell lung cancer.

This analysis was performed to create a scoring system to estimate the survival of patients with non-small cell lung cancer (NSCLC). Data from 1274 NSCLC patients were analyzed to create and validate a scoring system. Univariate (UV) and multivariate (MV) Cox models were used to evaluate the prognostic importance of each baseline factor. Prognostic factors that were significant on both UV and MV analyses were used to develop the score. These included quality of life, age, performance status, primary tumor diameter, nodal status, distant metastases, and smoking cessation. The score for each factor was determined by dividing the 5-year survival rate (%) by 10 and summing these scores to form a total score. MV models and the score were validated using bootstrapping with 1000 iterations from the original samples. The score for each prognostic factor ranged from 1 to 7 points with higher scores reflective of better survival. Total scores (sum of the scores from each independent prognostic factor) of 32-37 correlated with a 5-year survival of 8.3% (95% CI = 0-17.1%), 38-43 correlated with a 5-year survival of 20% (95% CI = 13-27%), 44-47 correlated with a 5-year survival of 48.3% (95% CI = 41.5-55.2%), 48-49 correlated to a 5-year survival of 72.1% (95% CI = 65.6-78.6%), and 50-52 correlated to a 5-year survival of 84.7% (95% CI = 79.6-89.8%). The bootstrap method confirmed the reliability of the score. Prognostic factors significantly associated with survival on both UV and MV analyses were used to construct a valid scoring system that can be used to predict survival of NSCLC patients. Optimally, this score could be used when counseling patients, and designing future trials.

Radiofrequency ablation of stage IA non-small cell lung cancer in medically inoperable patients: Results from the American College of Surgeons Oncology Group Z4033 (Alliance) trial.

BACKGROUND: This study evaluated the 2-year overall survival rate, adverse event rate, local control rate, and impact on pulmonary function tests for medically inoperable patients with stage IA non-small cell lung cancer (NSCLC) undergoing computed tomography (CT)-guided radiofrequency ablation (RFA) in a prospective, multicenter trial. METHODS: Fifty-four patients (25 men and 29 women) with a median age of 76 years (range, 60-89 years) were enrolled from 16 US centers; 51 patients were eligible for evaluation (they had biopsy-proven stage IA NSCLC and were deemed medically inoperable by a board-certified thoracic surgeon). Pulmonary function tests were performed within the 60 days before RFA and 3 and 24 months after RFA. Adverse events were recorded and categorized. Patients were followed with CT and fludeoxyglucose positron emission tomography. Local control rate and recurrence patterns were analyzed. RESULTS: The overall survival rate was 86.3% at 1 year and 69.8% at 2 years. The local tumor recurrence-free rate was 68.9% at 1 year and 59.8% at 2 years and was worse for tumors > 2 cm. In the 19 patients with local recurrence, 11 were re-treated with RFA, 9 underwent radiation, and 3 underwent chemotherapy. There were 21 grade 3 adverse events, 2 grade 4 adverse events, and 1 grade 5 adverse event in 12 patients within the first 90 days after RFA. None of the grade 4 or 5 adverse events were attributable to RFA. There was no significant change in the forced expiratory volume in the first second of expiration or the diffusing capacity of lung for carbon monoxide after RFA. A tumor size less than 2.0 cm and a performance status of 0 or 1 were associated with statistically significant improved survival of 83% and 78%, respectively, at 2 years. CONCLUSIONS: RFA is a single, minimally invasive procedure that is well tolerated in medically inoperable patients, does not adversely affect pulmonary function tests, and provides a 2-year overall survival rate that is comparable to the rate reported after stereotactic body radiotherapy in similar patients.

Analysis of longitudinal quality-of-life data in high-risk operable patients with lung cancer: results from the ACOSOG Z4032 (Alliance) multicenter randomized trial.

BACKGROUND: Prior studies have suggested that low baseline quality-of-life (QOL) scores predict worse survival in patients undergoing lung cancer surgery. However, these studies involved average-risk patients undergoing lobectomy. We report QOL results from a multicenter trial, American College of Surgeons Oncology Group Z4032, which randomized high-risk operable patients to sublobar resection (SR), or SR with brachytherapy, and included longitudinal QOL assessments. METHODS: Global QOL, using the 36-item Short-Form Health Survey (SF36), and the dyspnea score from the University of California, San Diego Shortness of Breath Questionnaire (SOBQ) scale, was measured at baseline, 3, 12, and 24 months. SF36 physical component summary (PCS) and mental component summary (MCS) scores were standardized and adjusted for age and gender normals, with scores <50 indicating below-average health status. SOBQ scores were transformed to a 0-100 (poor-excellent) scale. Aims were to: (1) determine the impact of baseline scores on recurrence-free survival, overall survival, and 30-day adverse events (AEs); and (2) identify subgroups (surgical approach, resection type. tumor location, tumor size, respiratory function) with a ≥ 10-point decline or improvement in QOL after SR. RESULTS: Two hundred twelve eligible patients were included. There were no significant differences in baseline QOL scores between arms. Median baseline PCS, MCS, and SOBQ scores were 42.7, 51.1, and 70.8, respectively. There were no differences in grade-3+ AEs, overall survival, or recurrence-free survival in patients with baseline scores ≤ median versus > median values, except for a significantly worse overall survival for patients with baseline SOBQ scores ≤ median value. There were no significant differences between the study arms in percentage change of QOL scores from baseline to 3, 12, or 24 months. Further comparison combining the 2 arms demonstrated a higher percentage of patients with a ≥ 10-point decline in SOBQ scores with segmentectomy compared with wedge resection (40.5% vs 21.9%, P = .03) at 12 months, with thoracotomy versus video-assisted thoracic surgery (VATS) (38.8% vs 20.4%, P = .03) at 12 months, and T1b versus T1a tumors (46.9% vs 23.5%, P = .020) at 24 months. A ≥ 10-point improvement in PCS score was seen at 3 months with VATS versus thoracotomy (16.5% vs 3.6%, P = .02). CONCLUSIONS: In high-risk operable patients, poor baseline QOL scores were not predictive for worse overall or recurrence-free survival, or for higher risk for AEs following SR. VATS was associated with improvement in physical function at 3 months, and improved dyspnea scores at 12 months, lending support for the preferential use of VATS when SR is undertaken.

Impact of brachytherapy on local recurrence rates after sublobar resection: results from ACOSOG Z4032 (Alliance), a phase III randomized trial for high-risk operable non-small-cell lung cancer.

PURPOSE: A major concern with sublobar resection (SR) for non-small-cell lung cancer (NSCLC) is high local recurrence (LR). Adjuvant brachytherapy may reduce LR This multicenter randomized trial compares SR to SR with brachytherapy (SRB). PATIENTS AND METHODS: High-risk operable patients with NSCLC ≤ 3 cm were randomly assigned to SR or SRB. The primary end point was time to LR, where LR included recurrence at the staple line (local progression), in the primary tumor lobe away from the staple line, and in ipsilateral hilar nodes. The trial was designed to have a 90% power to detect a hazard ratio (HR) of 0.315 in favor of SRB, using a one-sided type I error rate of 0.05 with a sample size of 100 eligible patients in each arm. RESULTS: Two hundred twenty-four patients were randomly assigned; 222 patients were evaluable for intent-to-treat analysis. Median age was 71 years (range, 49 to 87 years). No differences were found in baseline characteristics. Median follow-up time was 4.38 years (range, 0.04 to 5.59 years). There was no difference in time to LR (HR, 1.01; 95% CI, 0.51 to 1.98; log-rank P = .98) or in the types of LR. Local progression occurred in only 17 (7.7%) of 222 patients. In patients with potentially compromised margins (margin < 1 cm, margin-to-tumor ratio < 1, positive staple line cytology, wedge resection, nodule size > 2.0 cm), SRB did not reduce LR, although trends favored the SRB arm. This was most marked in 14 patients with positive staple line cytology (HR, 0.22; P = .24). Three-year overall survival rates were similar for patients in the SR (71%) and SRB (71%) arms (P = .97). CONCLUSION: Brachytherapy did not reduce LR after SR. This finding may have been related to closer attention to parenchymal margins by surgeons participating in this study.
