Randomized trial <strong>of</strong> vitamin D3 to prevent worsening <strong>of</strong> musculoskeletal<br />

symptoms and fatigue in women with breast cancer starting adjuvant<br />

letrozole: The VITAL trial. Presenting Author: Qamar J. Khan, University <strong>of</strong><br />

Kansas Medical Center, Kansas City, KS<br />

Background: Musculoskeletal (MS) pain and fatigue are common in women<br />

on adjuvant Aromatase Inhibitors (AIs) and lead to reduced compliance.<br />

Pilot studies suggest a positive impact <strong>of</strong> vit D on MS pain and disability<br />

from AIs. We conducted a bi-institutional, double blind, placebo controlled<br />

randomized trial to study the impact <strong>of</strong> 30,000 I.U <strong>of</strong> vit D3 in preventing<br />

worsening <strong>of</strong> MS pain and fatigue in women starting letrozole. Methods:<br />

Women with stage I-III breast cancer starting adjuvant AI and a 25(OH)D<br />

level <strong>of</strong> 40 ng/ml or less were eligible. Women with prior renal stones or<br />

hypercalcemia were excluded. All subjects received letrozole, plus standard<br />

dose vitD3 (600 IU) and calcium (1200 mg) daily, all provided by the<br />

study. Women were randomly assigned to 30,000 IU <strong>of</strong> oral vitD3 wkly (vitD<br />

arm) or matched placebos (PL arm) for 24 weeks. The following were<br />

assessed at baseline, 12 wks, and 24 wks (end <strong>of</strong> study): 1) 25OHD levels,<br />

2) symptoms tools (BFI – Brief Fatigue Inventory, HAQII - Health Assessment<br />

Questionnaire II, Qualitative Joint Pain (none, mild, moderate,<br />

severe), BPI – Brief Pain Inventory) and 3) hand grip strength with a<br />

dynamometer. Results: 160 women (80/arm) were enrolled from 4/09 to<br />

7/10. There were no differences between the two arms in demographics/<br />

tumor characteristics. Median age was 61, median BMI was 29.8 kg/m2.<br />

43% had adjuvant chemotherapy. Median 25OHD (ng/ml) was 25 at<br />

baseline, 32 at 12 wks and 31 at 24 wks in the PL arm and 22, 53 and 57<br />

in vitD arm. One patient in the PL arm developed mild hypercalcemia.<br />

There were no SAEs. 147 subjects were evaluable for efficacy. 3 subjects,<br />

all in the PL arm discontinued early due to a MS adverse event. At wk 24, a<br />

higher proportion <strong>of</strong> women in PL (51%) vs vitD arm (37%) had a protocol<br />

defined MS event (worsening <strong>of</strong> joint pain, disability from joint pain or<br />

discontinuation <strong>of</strong> Letrozole due to MS symptoms) (p�0.069). A significantly<br />

higher proportion <strong>of</strong> women in PL (72%) vs vitD arm (42%) had an<br />

adverse QOL event (worsening <strong>of</strong> pain, disability or fatigue) (p��0.001).<br />

Conclusions: 30,000 IU/week <strong>of</strong> vitamin D3 is safe and results in decreased<br />

adverse QOL events from adjuvant aromatase inhibitors in women with<br />

breast cancer.<br />

Dexamethasone (DM) for cancer-related fatigue: A double-blinded, randomized,<br />

placebo-controlled trial. Presenting Author: Sriram Yennurajalingam,<br />

University <strong>of</strong> Texas M. D. Anderson Cancer Center, Houston, TX<br />

Background: Cancer-related-fatigue (CRF) is the most common and distressing<br />

symptoms in patients with advanced cancer. Currently, there is no<br />

standard treatment for CRF. Although corticosteroids have been used in the<br />

treatment <strong>of</strong> CRF, there are no well-powered placebo-controlled trials that<br />

used a validated CRF outcome measure. The primary objective <strong>of</strong> this<br />

prospective, randomized, double-blind, placebo-controlled study is to<br />

compare the effect <strong>of</strong> DM versus placebo on CRF. Methods: Advanced<br />

cancer patients with fatigue � 4/10 on the Edmonton Symptom Assessment<br />

Scale (ESAS) and at least 2 other CRF-related symptoms (pain,<br />

nausea, appetite, depression, anxiety or sleep disturbance � 4/10), normal<br />

cognition, no infections and hemoglobin � 9 g/L were eligible for<br />

enrollment. Patients were randomized to either receive dexamethasone 4<br />

mg orally twice a day for 15 days (primary end point) or matching placebo.<br />

The primary outcome was the day 15 change in Functional Assessment <strong>of</strong><br />

Chronic Illness-Fatigue (FACIT-F) subscale scores. Differences in the group<br />

means (normal distribution) were analyzed using the two-sample t-test.<br />

Results: In 83 evaluable patients (43 DM and 40 placebo), median age was<br />

60 years, 61% were white, and 53% were female. There was no difference<br />

in the demographics and fatigue (FACIT-F subscale) between DM and<br />

placebo groups except for sex (p�0.02). The mean (SD) FACIT-F subscores<br />

at baseline and at day 15 for DM were 18 (11) and 27 (11) (p�0.001) and<br />

for placebo were 21 (9) and 24 (12) (p�0.06), respectively. Mean<br />

improvement in FACIT-F subscale was significantly higher in the DM group<br />

compared to placebo (9.6 (11) vs. 3.1 (9.7), p�0.005). We found a<br />

significant difference in ESAS physical distress (p�0.02), but no differences<br />

in ESAS overall symptom distress (p�0.11) and ESAS psychological<br />

distress (P�0.88) between DM and placebo. There were insignificantly<br />

higher numbers <strong>of</strong> grade �3 toxicities in patients who received DM than in<br />

patients who received placebo (20/42 vs. 18/47, p�0.37). Conclusions:<br />

Dexamethasone was more effective than placebo in reducing CRF in<br />

patients with advanced cancer. Long-term safety studies are needed.<br />

Phase III evaluation <strong>of</strong> <strong>American</strong> ginseng (panax quinquefolius) to improve<br />

cancer-related fatigue: NCCTG trial N07C2. Presenting Author: Debra L.<br />

Barton, Mayo Clinic, Rochester, MN<br />

Background: Ginseng is popularly used as a treatment for fatigue, one <strong>of</strong> the<br />

most common and disabling symptoms in people diagnosed with cancer. It<br />

is termed an “adaptogen”, thought to help the body combat negative<br />

effects <strong>of</strong> stress. This trial was to evaluate 2,000 mg <strong>American</strong> Ginseng<br />

versus placebo for cancer-related fatigue (CRF). Methods: Patients with<br />

cancer undergoing or having completed curative intent treatment and<br />

experiencing fatigue, rated at least 4 on a numeric analogue fatigue scale<br />

(1-10) for �1 month, were eligible. Exclusion criteria included CNS<br />

lymphoma, brain malignancies, or prior use <strong>of</strong> ginseng or chronic systemic<br />

steroids. Other etiologies for fatigue, such as pain and sleep, were also<br />

excluded. Patients were randomized to receive, in a double blind manner,<br />

2,000 mg/d <strong>of</strong> <strong>American</strong> Ginseng or placebo in BID dosing for 8 weeks. The<br />

primary endpoint was change from baseline in the general subscale <strong>of</strong> the<br />

Multidimensional Fatigue Symptom Inventory (MFSI) at 4 weeks. Other<br />

MFSI subscales and the fatigue-inertia subscale <strong>of</strong> the Pr<strong>of</strong>ile <strong>of</strong> Mood<br />

States (POMS) were also analyzed. Data were transformed to a 0-100 scale.<br />

Results: 364 patients were enrolled from 10/2008 to 07/2011. Data at 4<br />

and 8 weeks are provided for several fatigue endpoints in the table below;<br />

higher numbers are better. Mental, emotional and vigor subscales <strong>of</strong> the<br />

MFSI were not significantly different between arms. There were no<br />

statistically significant differences in any grade <strong>of</strong> toxicity or self reported<br />

side effects between ginseng and placebo. Conclusions: This trial provides<br />

data to support that <strong>American</strong> Ginseng reduces general and physical CRF<br />

over 8 weeks without side effects. The treatment did not provide significant<br />

reductions in fatigue at 4 weeks and did not impact mental, emotional, and<br />

vigor dimensions <strong>of</strong> fatigue.<br />

Cluster-randomized trial <strong>of</strong> early palliative care for patients with metastatic<br />

cancer. Presenting Author: Camilla Zimmermann, Princess Margaret Hospital,<br />

University Health Network, Toronto, ON, Canada<br />

Background: Patients with metastatic cancer have compromised quality <strong>of</strong><br />

life (QOL), which tends to worsen towards the end <strong>of</strong> life. We conducted a<br />

cluster-randomized trial <strong>of</strong> early versus routine palliative care in patients<br />

with metastatic cancer, to assess impact on QOL, symptom control and<br />

satisfaction with care. Methods: Twenty-four medical oncology clinics were<br />

randomized, stratified by tumour site (4 lung clinics, 8 gastrointestinal, 4<br />

genito-urinary, 6 breast, 2 gynecological), to intervention and follow-up (at<br />

least monthly) by a palliative care team, or to routine cancer care. Eligible<br />

patients had ECOG performance status 0-2 and a clinical prognosis <strong>of</strong> 6<br />

months to 2 years. Patients completed measures <strong>of</strong> QOL (FACIT-Sp,<br />

including physical, social, emotional, functional and spiritual well-being;<br />

range 0-156, with higher scores indicating better QOL), symptom severity<br />

(Edmonton Symptom Assessment System; range 0-90, with higher scores<br />

indicating worse symptom severity), and satisfaction with care (FAMCARE-<br />

P16; score range 16-80) at baseline and monthly for 4 months. The<br />

primary outcome was the change in FACIT-Sp at 3 months. The planned<br />

sample size was 225 patients per arm, assuming 80% power and a 2-sided<br />

significance level <strong>of</strong> 0.05. Results: From December 2006 to September<br />

2010, 461 patients completed baseline measures (228 intervention, 233<br />

control); 442 patients completed at least one follow-up assessment (mean<br />

patients/cluster 18.8�11.6 control, 18.1�12.6 intervention). At 3 months,<br />

patients in the intervention group had marginally improved QOL (mean<br />

change in intervention vs. control, 1.6�14.5 vs. -2.0�13.6, p�0.07) but<br />

not symptom severity (0.1�16.9 vs. 2.1�13.9, p�0.34). At 4 months the<br />

change in QOL was more marked (2.5�15.5 vs. -4.0�14.2, p�0.008)<br />

and symptom severity was marginally better (-1.3�16.0 vs. 3.2�13.9,<br />

p�0.05). Improvement in satisfaction with care was evident at one month<br />

(p�0.001) and remained significant at both 3 months (2.3�9.1 vs.-<br />

1.8�8.2, p�0.001) and 4 months (3.7�8.6 vs. -2.4�8.3, p�0.001).<br />

Conclusions: In patients with metastatic cancer, early palliative care<br />

intervention immediately improved satisfaction with care, while QOL and<br />

symptom control improved later.<br />
