Life expectancy (LE) and the receipt <strong>of</strong> conservative versus active treatment<br />
in men with prostate cancer (CaP): A population-based study. Presenting<br />
Author: Trevor Joseph Royce, UNC-CH School <strong>of</strong> Medicine, Chapel Hill, NC<br />
Background: Prostate-specific antigen (PSA) screening increases the diagnosis<br />
<strong>of</strong> low-risk and potentially clinically insignificant CaP, which raises<br />
concern for possible overtreatment. The National Comprehensive Cancer<br />
Network (NCCN) guidelines recommend surveillance (conservative management)<br />
for patients with less than 10 years LE diagnosed with low-risk<br />
cancer. In contrast, NCCN recommends active treatment for high-risk CaP,<br />
the most aggressive form <strong>of</strong> this disease, irrespective <strong>of</strong> LE. We examine<br />
patterns <strong>of</strong> care in CaP patients in the Surveillance, Epidemiology and End<br />
Results (SEER) registry by LE. Methods: 152,578 men with non-metastatic<br />
CaP diagnosed from 2004-8 were included. Gleason, PSA, and clinical<br />
stage were used for risk-categorization per D’Amico criteria. The sample<br />
was dichotomized into men 76 years and younger (who have an average LE<br />
<strong>of</strong> 10 years or more based on the US Social Security Administration<br />
actuarial period life tables) vs. 77 years and older (less than 10 years<br />
average LE). Logistic regression models examined factors associated with<br />
each treatment modality. Results: 56% <strong>of</strong> patients age 77 and older with<br />
low-risk CaP received conservative management, and 44% active treatment<br />
(Table). However, conservative management was just as common in<br />
older patients with high-risk cancer (62%); 21% <strong>of</strong> younger patients with<br />
high-risk CaP also received conservative management. Multivariable analysis<br />
showed decreased use <strong>of</strong> conservative management over time in older<br />
patients (OR 0.78 for 2008 vs. 2004, 95%CI 0.71-.86, p�.001). African<br />
<strong>American</strong> race, being unmarried, and older age were also significantly<br />
associated with conservative management. Conclusions: There may be<br />
overtreatment <strong>of</strong> low-risk CaP patients age 77 and older, which is worsening<br />
in recent years. Correspondingly, there appears to be undertreatment <strong>of</strong><br />
elderly patients with high-risk CaP, the most aggressive form <strong>of</strong> this<br />
disease.<br />

Do patients with advanced-stage non-small cell lung cancer (AS NSCLC)<br />
live longer if managed within a clinical trial setting? Presenting Author:<br />

Clinics, Iowa City, IA<br />
Background: Treatment outcomes <strong>of</strong> AS NSCLC (stages IIIB and IV) are<br />
poor. There is an argument that participation in a clinical trial (CT) may<br />
confer survival benefit, probably, through enhancing quality <strong>of</strong> care. In this<br />
study, we explore the survival outcomes and perceived care quality for AS<br />
NSCLC patients (pts) treated within vs outside a CT. Methods: Data were<br />
obtained from surveys <strong>of</strong> newly diagnosed AS NSCLC pts studied by the<br />
Cancer Care Outcomes Research and Surveillance Consortium (CanCORS),<br />
a large cohort <strong>of</strong> pts across the United States. Pts who did not complete the<br />
baseline survey were excluded as this was associated with worse performance<br />
status (PS). Baseline characteristics according to CT participation<br />
were determined. Association between CT enrollment and survival was<br />
explored utilizing univariate and multivariate survival analysis after adjusting<br />
for age, comorbidities and self-reported PS. Results: Of 815 AS NSCLC<br />
pts, 56 (7%) were enrolled on a CT. Chemotherapy trials comprised 67% <strong>of</strong><br />
all trials. Of the 815 pts, 697 (86%) died. Median survival for pts within vs<br />
outside a CT was 62 vs 64 months. Neither age, comorbidities nor recalled<br />
PS differed significantly between pts within vs outside a CT (P�0.2085,<br />
0.5818 and 0.1678 respectively). On the multivariate survival model, CT<br />
enrollment did not correlate with longer survival (P�0.8811) and only<br />
presence <strong>of</strong> comorbidities was associated with worse survival (P�0.0021).<br />
Comparing pts according to CT enrollment, there was no significant<br />
difference in symptom management, receiving hospice care (P�0.606),<br />
death location (P�0.2018), or following pts’ wishes (P�0.8321). However,<br />
perception <strong>of</strong> the overall cancer care quality was greater among CT<br />
enrollees (P�0.0171). Conclusions: Management <strong>of</strong> AS NSCLC pts within<br />
a CT setting conveyed a perception <strong>of</strong> superior care that did not translate<br />
into survival benefit after adjusting for differences in age, comorbidities,<br />
and self-reported PS. These findings suggest that providing cancer care<br />
within a CT should not imply a survival benefit when counseling AS NSCLC<br />
pts about entering CTs.<br />

Timeliness <strong>of</strong> care and stage at diagnosis <strong>of</strong> non-small cell lung cancer<br />
(NSCLC) with the implementation <strong>of</strong> a cancer care coordination program<br />
(CCCP) at a VA medical center. Presenting Author: Susan Alsamarai,<br />
Yale-New Haven Hospital, New Haven, CT<br />
Background: Timeliness <strong>of</strong> care improves patient satisfaction and may<br />
improve outcomes. A CCCP was established in Nov 2007 to improve<br />
timeliness <strong>of</strong> care <strong>of</strong> NSCLC patients at the Veterans Affairs Connecticut<br />
(VACT) Healthcare System. Methods: We performed a retrospective cohort<br />
analysis <strong>of</strong> patients diagnosed with NSCLC at VACT between 2005-2010.<br />
We compared timeliness <strong>of</strong> care and stage at diagnosis before and after the<br />
implementation <strong>of</strong> the CCCP. Results: Data from 352 patients was<br />
analyzed: 163 with initial abnormal imaging between 1/1/2005 and<br />
10/31/2007, and 189 with imaging between 11/1/2007 and 12/31/2010.<br />
Variables associated with a longer interval between the initial abnormal<br />
image and the initiation <strong>of</strong> therapy were: (1) earlier stage (mean <strong>of</strong> 130<br />
days for stages I/II vs. 87 days for stages III/IV, p�0.001),(2) lack <strong>of</strong><br />
cancer-related symptoms (145 vs 60 days, p�0.001), (3) presence <strong>of</strong><br />
medical co-morbidities (111 vs 76 days, p�0.01), and (4) depression<br />
(127 vs 98 days, p�0.029). Substance abuse increased the interval from<br />
initial abnormal image to tissue diagnosis by 29 days (p�0.032) but did<br />
not affect the interval from image to treatment. The mean interval between<br />
diagnosis and initiation <strong>of</strong> treatment was 19 days longer in blacks vs.<br />
non-blacks (55 vs 36 days, p�0.0118) although the overall time from<br />
abnormal image to diagnosis and to treatment was not statistically<br />
different. In a multivariate model adjusting for stage, histology, reason for<br />
initial imaging, and presence <strong>of</strong> a primary care provider, implementation <strong>of</strong><br />
a CCCP resulted in a mean reduction <strong>of</strong> 25 days in the time between the<br />
first abnormal image and initiation <strong>of</strong> cancer treatment (126 to 101 days,<br />
p�0.0154). The percent <strong>of</strong> patients diagnosed at stages I and II increased<br />
from 32% to 48% (p�0.0065) after the implementation <strong>of</strong> a CCCP.<br />
Conclusions: A centralized, multidisciplinary, hospital-based CCCP can<br />
improve timeliness <strong>of</strong> NSCLC care, and may also help ensure that<br />
incidental, early stage lung cancers are treated.<br />

Results <strong>of</strong> a cluster randomized trial to evaluate a nursing lead supportive<br />
care intervention in newly diagnosed breast and colorectal cancer patients.<br />
Presenting Author: Jonathan Sussman, Juravinski Cancer Centre, Hamilton,<br />
ON, Canada<br />
Background: Patient transitions during the early phases <strong>of</strong> cancer care from<br />
initial diagnosis through oncology consultation are <strong>of</strong>ten poorly coordinated<br />
resulting in unmet need, poor continuity, and resultant distress. It has been<br />
proposed that better coordination <strong>of</strong> care during this period would improve<br />
the care experience from the patient’s perspective. We designed a<br />
randomized trial to test a community based nursing lead coordination <strong>of</strong><br />
care intervention in newly diagnosed breast and colorectal cancer patients.<br />
Methods: Cluster randomized control trial in 193 newly diagnosed breast<br />
and colorectal cancer patients enrolled through surgical practices within 7<br />
days <strong>of</strong> cancer surgery in Toronto, Canada. Surgical practices were<br />
randomized between a standardized nursing intervention and a control<br />
group involving usual care practices. The intervention consisted <strong>of</strong> a<br />
standardized in person supportive care assessment with ongoing supportive<br />
care by telephone or in person that included linkage to community services<br />
using protocol specified guidelines according to identified needs. The<br />
primary outcomes measured at 8 weeks were validated patient reported<br />
outcomes (PROs) <strong>of</strong> 1) unmet need (SCNS) and 2) continuity <strong>of</strong> care<br />
(CCCQI). Secondary outcomes included 1) quality <strong>of</strong> life (EORTC QLQ-<br />
C30), 2) health resource utilization, and 3) level <strong>of</strong> uncertainty with care<br />
trajectory (MUIS) at 8 weeks. Results: 121 breast and 72 colorectal<br />
patients were randomized through 28 surgical practices. The intervention<br />
group had a median <strong>of</strong> 6 nursing contacts over the study period. There were<br />
no differences between groups on PROs <strong>of</strong> unmet need, continuity <strong>of</strong> care,<br />
quality <strong>of</strong> life, or uncertainty. Health service utilization did not differ<br />
between groups. Conclusions: A specialized oncology nursing intervention<br />
early in the care trajectory did not result in improved supportive care<br />
outcomes for patients.<br />
