The objective of this study is

1. to develop a web-based, tailored program for Cancer-related fatigue in cancer survivors, which is comprehensive and evidence-based,
2. to evaluate the efficacy for cancer-related fatigue as a result of participating in the Web based, tailored program(Health Navigation®) for 12 weeks
3. to evaluate the efficacy for quality of life, fatigue-related behavior, satisfaction with the treatment as a result of participating in the Web based, tailored program(health navigation®) for 12 weeks
4. to assess the efficacy of such intervention compared with usual care in cancer survivors

*** Background

Cancer-related fatigue (CRF) and its impact on patients' quality of life has been increasing subject of research. Especially, cancer survivors who are complaining of fatigue (moderate - severe) should be cared.

Multidimensional characteristics of CRF were addressed in the NCCN guideline for CRF, and NCCN guideline points out the importance of behavioral approaches in managing of CRF.

NCCN guideline in 2008 suggests that 6 strategic areas (1) Energy Conservation, 2) Pain 3) Sleep disturbance 4) Distress 5) exercise, 6) Nutrition) are important issues in caring CRF in addition to the medical treatment caring chronic disease or co morbidity.

Behavioral strategy can lead those 6 areas to be effective.

However, to our knowledge, no study has examined the comprehensive fatigue management program.

The objective of this study is to develop the Web based, tailored program(Health Navigation®) for disease-free cancer patients to cope with CRF, and then evaluate the efficacy of the Web-based program(Health Navigation®).

From evidence extracted from a literature review, contents of the program was elaborated, and tailored from the TTM model. The curriculum is currently being reviewed and validated by an expert group of palliative care physician, oncologists, nurse, psychologist and health education scientists. The module will be pretested with a small number of patients, discussed in terms of feasibility and acceptance.

*** Method

To determine the efficacy of the program(Health Navigation®), a randomized controlled trial will be conducted:

After excluding patients with other causes (anemia, thyroid diseases, liver disease, co morbidities etc), 296 patients will be recruited based on statistical assumption of alpha (0.05), beta (0.20=power 80%), effect size (0.375) and drop out rate (10%).

First, they will be stratified according to their age (<50 vs. >50) and sex (male vs. female), cancer type (type 1: stomach cancer & colon cancer, type 2: Cervix & Breast cancer & Thyroid, type 3 : Lung cancer ), cancer stage (I-III) ; and then allocated to an intervention or a wait-list control group.

When intervention group participate in the Web-based care program (Health Navigation®), they can receive various information which is related with the CRF.

And Web-based fatigue care program consists of 6 strategic areas (energy conservation, nutrition, exercise, sleep disturbance, pain, and distress); three areas (pain, exercise, sleep disturbance) are based on the transtheoretical model (TTM), and others (energy conservation, distress, nutrition) are based on psycho-education method or cognitive behavioral therapy. Cancer survivors who participate in the Web-based care program (Health Navigation®) will be received tailored EMS/SMS message that notify participants of the next program's news and the last program's issue etc.

Their assistants (family member or friend) help them change their behaviors. Wait-list (control) group could not participate in the fatigue-care program (based on the Web based care program: Health Navigation®).

They could only be treated by usual care and use internet for health information. However, they can participate in the fatigue care program (Health Navigation®) after 12 weeks.

Data will be collected before randomization, after intervention, and after a follow-up of 6 months.
