RESUMO
BACKGROUND: High-quality care must be not only appropriate but also timely. We assessed time to initiation of adjuvant chemotherapy for breast cancer as well as factors associated with delay to help identify targets for future efforts to reduce unnecessary delays. METHODS: Using data from the National Comprehensive Cancer Network (NCCN) Outcomes Database, we assessed the time from pathological diagnosis to initiation of chemotherapy (TTC) among 6622 women with stage I to stage III breast cancer diagnosed from 2003 through 2009 and treated with adjuvant chemotherapy in nine NCCN centers. Multivariable models were constructed to examine factors associated with TTC. All statistical tests were two-sided. RESULTS: Mean TTC was 12.0 weeks overall and increased over the study period. A number of factors were associated with a longer TTC. The largest effects were associated with therapeutic factors, including immediate postmastectomy reconstruction (2.7 weeks; P < .001), re-excision (2.1 weeks; P < .001), and use of the 21-gene reverse-transcription polymerase chain reaction assay (2.2 weeks; P < .001). In comparison with white women, a longer TTC was observed among black (1.5 weeks; P < .001) and Hispanic (0.8 weeks; P < .001) women. For black women, the observed disparity was greater among women who transferred their care to the NCCN center after diagnosis (P (interaction) = .008) and among women with Medicare vs commercial insurance (P (interaction) < .001). CONCLUSIONS: Most observed variation in TTC was related to use of appropriate therapeutic interventions. This suggests the importance of targeted efforts to minimize potentially preventable causes of delay, including inefficient transfers in care or prolonged appointment wait times.

Few randomized trials have compared therapies in mantle cell lymphoma (MCL), and the role of aggressive induction is unclear. The National Comprehensive Cancer Network (NCCN) Non-Hodgkin Lymphoma (NHL) Database, a prospective cohort study collecting clinical, treatment, and outcome data at 7 NCCN centers, provides a unique opportunity to compare the effectiveness of initial therapies in MCL. Patients younger than 65 diagnosed between 2000 and 2008 were included if they received RHCVAD (rituximab fractionated cyclophosphamide, vincristine, adriamycin, and dexamethasone), RCHOP+HDT/ASCR (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone + high-dose therapy/autologous stem cell rescue), RHCVAD+HDT/ASCR, or RCHOP. Clinical parameters were similar for patients treated with RHCVAD (n = 83, 50%), RCHOP+HDT/ASCR (n = 34, 20%), RCHOP (n = 29, 17%), or RHCVAD+HDT/ASCR (n = 21, 13%). Overall, 70 (42%) of the 167 patients progressed and 25 (15%) expired with a median follow-up of 33 months. There was no difference in progression-free survival (PFS) between aggressive regimens (P > .57), which all demonstrated superior PFS compared with RCHOP (P < .004). There was no difference in overall survival (OS) between the RHCVAD and RCHOP+HDT/ASCR (P = .98). RCHOP was inferior to RHCVAD and RCHOP+HDT/ASCR, which had similar PFS and OS. Despite aggressive regimens, the median PFS was 3 to 4 years. Future trials should focus on novel agents rather than comparing current approaches.

PURPOSE: It is expected that over the next 10 to 15 years, demand for oncology services will increase, potentially surpassing the supply of available oncologists. Physician assistants (PAs) and nurse practitioners (NPs) have the potential to address the anticipated shortage in physician supply. The two objectives of this study were to define how National Cancer Institute (NCI) -designated comprehensive cancer centers use PAs/NPs and to pilot a self-reported PA/NP productivity tool. METHODS: An online survey addressing practice patterns and productivity in 4-hour outpatient oncology clinics was administered to PAs/NPs practicing at 15 National Comprehensive Cancer Network member institutions. RESULTS: A total of 206 PAs/NPs were included in the final analysis. NPs and PAs reported similar clinical activities, with the following exceptions: NPs reported spending more time on telephone triage, and PAs reported spending more time on procedures. Overall, PAs/NPs reported seeing more follow-up (mean, 6.1; standard deviation [SD], 3.5) than new patients (mean, 1.2; SD, 1.3) per clinic. NPs with a medical oncology specialty reported a marginally greater productivity among follow-up patients than did PAs. Otherwise, NPs and PAs saw a similar number of patients regardless of specialty. CONCLUSION: To our knowledge, this is the first study attempting to characterize PA/NP clinical activities and define productivity benchmarks at NCI-designated comprehensive cancer centers. Given the increasing complexity of oncologic care and the increased population of patients with cancer and cancer survivors requiring that care, PAs/NPs have the potential to fill important roles in both outpatient and inpatient care settings.
