Primary Outcome Measures
NameTimeMethod
Progression-free survival3 years (and more) after recruitment

The data progression-free survival will be done by reviewing patients' medical record.

Secondary Outcome Measures
NameTimeMethod
Objective sleep cycle measuresBaseline, after 1 month, after 6 month, after 12 month

The assessment will be performed by using actigraph and sleep diary.

Sleep quality measuresBaseline, after 1 month, after 6 month, after 12 month

The measurements will be performed using Epworth sleepiness scale, Pittsburgh Sleep Quality Index, and Insomnia Severity Index.

Distress related measureBaseline, after 1 month, after 6 month, after 12 month

Hospital Anxiety and Depression Scale will be used during the assessment.

Posttraumatic Stress-related symptom measureBaseline, after 1 month, after 6 month, after 12 month

Impact of Event Scale-revised will be used to categorize and quantify Posttraumatic stress-related symptom in cancer patients.

Genetic polymorphismBaseline

Variable Number Tandem Repeat and Single Nucleotide Polymorphism of circadian-rhythm related genes will be examined.

Physiological measuresBaseline, after 1 month, after 6 month, after 12 month

The measures include blood pressure, body temperature, skin conductance, breathing pattern, and Electroencephalography.

Cortisol levelBaseline

Salivary cortisol level will be measured multiple times at baseline.

Inflammatory markersBaseline

The various inflammation markers will be measured from blood sample.

Overall survival3 years (and more) after recruitment

The data progression-free survival will be done by reviewing patients' medical record.

Quality of Life measureBaseline, after 1 month, after 6 month, after 12 month

The measurement will be performed using M.D. Anderson Symptom Inventory.

Cancer related FatigueBaseline, after 1 month, after 6 month, after 12 month

Fatigue severity scale will be used during the assessment.

Menopausal symptom measureBaseline, after 1 month, after 6 month, after 12 month

Menopause Rating Scale will be used during the assessment.

Epigenetic ChangeBaseline

The methylation specific Polymerase Chain Reaction technique will be used to explore methylation patterns in circadian clock gene or in a global gene level.

Circadian disruptionBaseline, after 1 month, after 6 month, after 12 month

Morningness-Eveningness Questionnaire and Munich Chronotype Questionnaire will be used during assessment.

Personality measureBaseline

Temperament and Character Inventory will be used to examine the personality factor in each participant.

MelatoninBaseline

Salivary or Urine melatonin level will be measured.
