Intervention name:
Yoga (intervention) group
Description:
The yoga (intervention) group comprises 64 women with breast cancer who have been
randomly assigned and are undergoing endocrine therapy. To alleviate arthralgia and
vasomotor symptoms (hot flashes, night sweats), a structured yoga program will be
administered during the initial months of endocrine therapy, consisting of 60-minute
sessions, 4 days per week, for a duration of one month.
Arm group label:
Yoga (intervention) Group
Summary:
The goal of this randomized controlled trial is to evaluate the effect of a yoga program
on improving the quality of life, reducing joint pain, and alleviating vasomotor symptoms
(night sweats, hot flashes) in women with breast cancer undergoing endocrine therapy.
The main questions it aims to answer are:
Does the yoga program significantly improve the quality of life in women with breast
cancer undergoing endocrine therapy? Is the yoga program effective in reducing joint pain
in women with breast cancer? Does the yoga program reduce the severity of night sweats
and hot flashes in women with breast cancer? Researchers will compare the intervention
group, which will receive the yoga program, to the control group, which will continue
with their physician-recommended routine exercise, to see if there is a difference in
these outcomes.
Participants will: Participants will consist of women with breast cancer undergoing
endocrine therapy, with 64 in the yoga (intervention) group and 64 in the control group.
Complete the;Patient Assessment Form; and the Functional Assessment of Cancer Therapy -
Endocrine Symptoms (FACT-ES) scale.
The intervention group will participate in a 60-minute yoga program, delivered online via
a digital platform, four days a week for four weeks, led by an instructor.
The control group will not receive any intervention and will continue with their
physician-recommended routine exercise.
Detailed description:
The goal of this randomized controlled trial is to evaluate the effect of a yoga program
on improving the quality of life, reducing joint pain, and alleviating vasomotor symptoms
(such as night sweats and hot flashes) in women with breast cancer undergoing endocrine
therapy. The participants will be divided into two groups: 64 women in the yoga
(intervention) group and 64 women in the control group.
Hypotheses:
H1: The yoga program will significantly improve the quality of life in women with breast
cancer undergoing endocrine therapy.
H1: The yoga program will be effective in reducing joint pain in women with breast
cancer.
H1: The yoga program will be effective in reducing the severity of night sweats and hot
flashes in women with breast cancer.
Population:
The study population consists of women who have completed surgical treatment in oncology
units, have completed chemotherapy or radiation therapy, and have recently started
adjuvant endocrine therapy. The sample size, calculated using G power with an effect size
of 0.5, a 5% error margin, and 80% power, includes 128 participants (64 in the
intervention group and 64 in the control group), taking into account possible data
losses.
Data Collection Tools:
The research data will be collected using the; Patient Identification Form and the
Functional Assessment of Cancer Therapy - Endocrine Symptoms (FACT-ES) scale.
Patient Identification Form: Developed by the researcher based on literature, this form
consists of two sections. The first section includes personal characteristics such as
age, gender, education level, and body mass index. The second section investigates
medical history, general health information, and lifestyle habits (e.g., smoking, alcohol
use, diet, and sleep patterns).
Functional Assessment of Cancer Therapy - Endocrine Symptoms (FACT-ES): This
comprehensive scale was developed to evaluate the quality of life of cancer patients,
particularly those receiving endocrine therapy. The scale consists of 46 items rated on a
scale from 0 to 4, and it includes five main subscales: Physical Well-Being,
Social/Family Well-Being, Emotional Well-Being, Functional Well-Being, Endocrine Symptom
Subscale. Some negatively worded items are reverse-scored, and raw scores are totaled.
Subscale scores are calculated separately, and the total score is the sum of the subscale
scores. Higher scores indicate better quality of life and fewer symptoms. The scale can
be scored manually, and appropriate prorating methods are applied in the case of missing
data. It is valid for cancer patients aged 18 and over, assessing experiences over the
past seven days. The assessment is conducted using a 5-point Likert scale and takes
approximately 10-15 minutes. It can be administered both in paper form and
electronically, and completed via self-reporting or interviews if necessary.
Process:
Participants in both the intervention and control groups will be informed about the
purpose and steps of the study, and the Informed Consent Form will be read and signed.
Written and verbal consent will be obtained from those who agree to participate in the
study. In the initial phase, data will be collected via face-to-face interviews using the
Patient Assessment Form along with weight measurement and basic movements (e.g., standing
while touching toes for 30 seconds, raising arms overhead, moving from standing to
sitting position). The FACT-ES scale will also be administered during this interview.
Data collection will continue using digital communication tools every two weeks once the
online yoga program begins.The intervention group will participate in a 60-minute yoga
program, delivered online via a digital platform, four days a week for four weeks, led by
an instructor. The control group will not receive any intervention and will continue with
their physician-recommended routine exercise.
Yoga Program (Intervention Group):
Participants in the intervention group will participate in a 60-minute yoga program,
delivered online via a digital platform, four days a week for four weeks.
Each session will begin with breathing exercises (pranayama), followed by yoga postures
(asanas), and end with meditation.
While the yoga program continues, the Endocrine Symptoms Subscale of the FACT-ES scale
will be applied in the 2nd week.
Since the program is conducted online, participants will be advised to perform yoga in a
quiet and hygienic environment conducive to practice.
Before starting the yoga practice, participants will be provided with a yoga guide by the
researcher.
An introductory session will be held to explain the philosophy of yoga and the details of
the program.
Yoga mats, blocks, and other necessary equipment will be provided to participants before
starting the practice.
After each yoga session, participants will be asked to provide feedback on any adverse
effects they may have experienced, which will be recorded through digital communication
tools.
One month after completing the four-week online yoga program, participants will be asked
how often they have continued the yoga practice at home, and this will be recorded.
Participants who do not continue yoga practice will be asked to provide reasons, which
will also be recorded.
Yoga Program Structure:
Warm-up (10 minutes) Pranayama (Breathing Exercise) - 5 minutes Dirga Pranayama

Data Analysis: The data obtained from the study will be analyzed using the IBM SPSS
Statistics 23 (IBM SPSS, Turkey) software. To test for the normality of the data
distribution, the Kolmogorov-Smirnov test will be used. Values with skewness and kurtosis
between ±2.0 will be considered to have a normal distribution. Descriptive statistics
such as mean, standard deviation, percentage, and frequency will be used. If the data
show a parametric distribution, One-Way Analysis of Variance (ANOVA) will be used for
comparisons between more than two groups, and Repeated Measures ANOVA will be applied for
repeated measurements. To determine the differences in quality of life scores between
groups, an independent samples t-test will be conducted. If the data do not show a normal
distribution, the Mann-Whitney U test will be applied. In addition, the Chi-Square test
will be used to evaluate sociodemographic differences. A significance level of p will be
considered the threshold for statistical significance. Finally, Cohen d will be
calculated to evaluate effect size.
