BACKGROUND: In hematopoietic cell transplantation (HCT), current risk adjustment strategies are based on clinical and disease-related variables. Although patient-reported outcomes (PROs) predict mortality in multiple cancers, they have been less well studied within HCT. Improvements in risk adjustment strategies in HCT would inform patient selection, patient counseling, and quality reporting. The objective of the current study was to determine whether pre-HCT PROs, in particular physical health, predict survival among patients undergoing autologous or allogeneic transplantation. METHODS: In this secondary analysis, the authors studied pre-HCT PROs that were reported by 336 allogeneic and 310 autologous HCT recipients enrolled in the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0902 protocol, a study with broad representation of patients who underwent transplantation in the United States. RESULTS: Among allogeneic HCT recipients, the pre-HCT Medical Outcomes Study Short Form-36 Health Survey (SF-36) physical component summary (PCS) scale independently predicted overall mortality (hazards ratio, 1.40 per 10-point decrease; P<.001) and performed at least as well as currently used, non-PRO risk indices. Survival probability estimates at 1 year for the first, second, third, and fourth quartiles of the baseline PCS were 50%, 65%, 75%, and 83%, respectively. Early post-HCT decreases in PCS were associated with higher overall and treatment-related mortality. When adjusted for patient variables included in the US Stem Cell Therapeutic Outcomes Database model for transplant center-specific reporting, the SF-36 PCS retained independent prognostic value. CONCLUSIONS: PROs have the potential to improve prognostication in HCT. The authors recommend the routine collection of PROs before HCT, and consideration of the incorporation of PROs into risk adjustment for quality reporting. © 2015 American Cancer Society.

Background: Postoperative cisplatin and radiation is the standard of care for high-risk squamous cell carcinoma of the head and neck (SCCHN). We have used cetuximab and radiation in the postoperative setting for patients deemed poor candidates for cisplatin. Methods: We retrospectively identified 40 patients who received cetuximab and radiation for resected locoregionally advanced SCCHN between 2006 and 2013 at our institution. Results: The 2-year Kaplan-Meier estimates were: overall survival (OS) 41%, recurrence-free survival (RFS) 34%, locoregional control 63%, and distant metastatic control 59%. Eastern Cooperative Oncology Group (ECOG) performance status ≥1 predicted for inferior OS (hazard ratio [HR] = 5.43; p = .003), RFS (HR = 4.07; p = .007), and locoregional control (HR = 4.92; p = .04) in multivariate analysis. Conclusion: Patients with resected high-risk SCCHN treated with postoperative cetuximab and radiation have suboptimal therapeutic outcomes. Further study of the efficacy and cost-effectiveness compared to radiation alone is warranted. © 2016 Wiley Periodicals, Inc.

Tyrosine kinase inhibitor (TKI) therapy yields sustained cytogenetic remissions in most patients with chronic-phase chronic myeloid leukemia (CML). Peripheral blood quantitative reverse transcription polymerase chain reaction (qRT-PCR) monitoring of the chimeric BCR-ABL1 mRNA transcript levels is a very sensitive method to measure disease burden in patients with cytogenetic remission. qRT-PCR allows identification of patients (1) at high risk of progression early (3-6 months) after treatment initiation, (2) with no response to TKI therapy, (3) with undetectable disease who could be eligible for TKI discontinuation trials. Molecular monitoring is a minimally invasive method to optimize treatment and outcomes in CML. © 2016 Wiley Periodicals, Inc.
