METHODS
Literature search on the subject was searched in Ebscohost, Cochrane Library, ProQuest, PubMed,
Science Direct, Google Scholar, Web of Science, and DergiPark databases between April 1 and May 1,
2023. The inclusion and exclusion criteria of the study were determined in accordance with the population,
intervention, comparison, outcome and study design, studies published in peer-reviewed journals
in systematic review, published in English and Turkish, with cancer patients aged 18 years and over, and
the full text of which can be accessed. RoB 2 and ROBINS-l assessment tools were utilized to evaluate
the risk of bias in the included studies.
RESULTS
In the study, 877 studies were analyzed and randomized controlled (n=10) and quasi-experimental studies
(n=3) were identified that met the inclusion criteria. It was determined that the physiological and
psychological symptoms decreased and the quality of life increased with the telehealth applications. In
only one study, it was determined that telehealth application did not change the quality of life, and in
another study, it had no effect on diarrhea symptoms.
CONCLUSION
There is no optimal duration and technique of telehealth application used in symptom control of cancer
diseases. The applied telehealth method has increased the quality of life by providing symptom control.
For this reason, it is recommended that health professionals should include telehealth applications in the
care practices of cancer patients, both in symptom control and in improving their quality of life.

Treatment methods for cancer vary according to the
stage and characteristics of the disease. Cancer patients
experience negative symptoms due to the cancer disease
and its treatments. It can cause many problems such as
pain, nausea, vomiting, oral mucositis, fatigue, anemia,
neutropenia, sleep disorders, and thrombocytopenia.

Telehealth is the delivery, management, and coordination
of health-care services that integrate information
and telecommunication technologies to provide a wide
range of health-care services.[

Limitation of the Research and Contribution to
the Field
Methodological differences such as the forms and scales
used in the studies, the number and composition of the
sample, and the type and interpretation of relevant variables
are important limitations. This study is important
for health professionals, who are users of telehealth applications,
to include telehealth applications in their care
plans, and to guide the planning of experimental studies
on this subject in our country. Telehealth applications
will contribute to the literature, patients, health-care
professionals, and managers to follow and control the
symptoms of cancer patients, increase access to healthcare
services, maintain treatment, and improve health
outcomes such as quality of life, morbidity, and mortality.
Inclusion and exclusion criteria were determined in accordance
with population, intervention, comparison,
outcome and study design,[
The database search was conducted by the researchers.
The PRISMA-P flowchart in Figure
Two independent researchers (FA-ÖÖ) were involved
at each stage of this review. The search strategy, date of
searches in each database, search terms, and number of
publications found were recorded. A PRISMA-P flowchart
was created to document the selection of eligible
publications and the total number of articles. The articles
found in the scans were exported to create a Mendeley
database. Duplications were found by calculating with
the Rayyan database. All reviews were used to filter article
titles and abstracts by inclusion/exclusion criteria and
categorized by one researcher (FA). The other researcher
(ÖÖ) examined the titles and summaries in the exclusion
category. The full text was independently assessed
for appropriateness by two researchers (FA-ÖÖ). For all
excluded studies, the reason for exclusion was noted in
the PRISMA flowchart. It was approved by the research
members before screening began. One researcher (FA)
extracted data from the included articles and completed
the database. The other researcher (ÖÖ) independently
checked the accuracy of the data extraction and database.
In terms of the quality of the studies included in the review,
ten randomized controlled trials21 were evaluated by the investigators (FA, ÖÖ) according to the checklist
for randomized controlled trials created by the Joanna
Briggs Institute (JBI). It consists of 13 items and the items
in the checklist assess selection, performance, identification,
and omission bias. Each item in the checklist is
scored as "Yes=1, No=0, Uncertain=0, or Not Applicable=
0." The maximum score for randomized controlled
experimental studies is 13. The higher the total score
of the studies, the higher the methodological quality.
[
The quality of the selected randomized controlled trials
was assessed according to six criteria (randomization
process, deviations from the intended interventions,
outcome measurement bias, missing outcome data, reported
outcome bias, and overall bias) in the Cochrane
Risk of Bias (RoB 2). According to these criteria, the
risk of bias of the studies was classified as "high risk
of bias," "risk of suspected bias," and "low risk of bias" (Table
Since the research data were obtained from publications
scanned from the literature, there is no need for
Ethics Committee approval. All articles included in the
study were cited and indicated in the bibliography. The
research protocol was registered in the PROSPERO
(International Prospective Register of Systematic Reviews)
database, which allows the registration of systematic
reviews and meta-analysis studies, with the
registration number CRD42023417975.
This systematic review is limited to the databases searched
and the studies conducted between 2000 and 2023, the
full text of which can be accessed, written in Turkish and
English languages, and no Turkish study was found as a
result of the searches. Another limitation is that studies
other than randomized controlled trials and quasi-experimental
studies were not included in the review. The
study was limited to n=13 studies included in the sample.
Evaluation of Methodological Quality of Studies
and Risk of Bias
Randomized controlled trials included in the systematic
review received an average score of 9 (min:9;
max:13) in the methodological quality assessment, and
quasi-experimental studies received an average score of
6 in the methodological quality assessment (Table

Country
The reviewed studies were conducted in the United
Kingdom (n=1), United States of America (n=6),
Netherlands (n=1), Taiwan (n=1), Australia (n=2), and
Türkiye (n=2). The study was conducted within units
and institutions such as cancer center, university hospitals,
medical center, and chemotherapy unit.
Participant
The total number of participants in the studies included
in the systematic review was 1164 and consisted of patients
diagnosed with breast cancer, colorectal cancer,
lung cancer, ovarian cancer, head and neck cancer, cancer
patients, prostate cancer, and upper gastrointestinal
cancer. The ages of the participants who accepted to the
study were 18 years and older (Table

Evaluation Criteria
Impact of Telehealth Interventions on Symptom
Management
The studies included in the systematic review, used mobile
phone-based remote monitoring,[
In the studies analyzed, the intervention period varied
between a minimum of 2.5 months and a maximum of
4.5 months.[
The evaluation criteria for the studies included in the
systematic review were physiologic symptoms, psychological
symptoms, and quality of life measures. Secondary
outcomes include social support,[
In the studies included in the systematic review, the effect
of telehealth intervention on symptom management
in cancer patients and the effectiveness of telehealth after
the intervention were evaluated (Table
It is seen that telehealth applications applied in
the studies included in the review were applied to patients
diagnosed with cancer such as breast cancer,
colorectal cancer, ovarian cancer, head and neck cancer,
lung cancer, prostate cancer, gastrointestinal cancer,[
Telehealth application is known to be effective in the
symptom management of cancer patients[
Most of the interventions usually took place over
a period of 2.5-4.5 months. Interventions were provided
on a weekly basis, either once or twice a week.
These different interventions prevented comparisons according to the length or frequency of the intervention.
The studies did not apply a specific duration to a
specific symptom, and the optimal duration, how long
it should be applied and monitored, is unclear. These
interventions were applied to cancer patients undergoing
treatment, but it was not specified which drugs and
doses were used with the telehealth intervention.
In a study published in 2011, Porter suggested that
different types of interventions may be more or less effective
depending on the stage of the disease.[
It is noteworthy that seven of the 13 studies included
in our study were created with telehealth interventions[
Physiological Symptoms
Cognitive behavioral intervention,[
Web-based training[
To manage the symptom of fatigue, advice on
pharmacological use, use of distraction and relaxation
techniques, dietary advice,[
One of the telehealth applications for diarrhea
symptom is a web-based application[
In some studies, the symptoms assessed were
not clear.[
Psychological Symptoms
Web-based training applications[
To manage the stress symptom, cognitive behavioral
intervention by telephone,[
Quality of Life
When we examine the studies included in the review
one by one, it is seen that telehealth interventions are
generally effective in symptom management. However,
it is not clear whether telephone interventions alone or
video-based applications or a combination of both are
more effective in symptom management of cancer patients.
In addition, there is heterogeneity in the studies.
It is seen that similar symptoms are not evaluated with
similar scales (Table
The interventions included in our research were developed
for physiological symptoms pain,[
In the interventions included in the review, it is seen
that telehealth applications applied for psychological
symptoms of cancer such as stress,[
Telehealth interventions improve the quality of life of
individuals with cancer by providing symptom management.[
As a result, studies have reported that telehealth applications are effective in symptom control of cancer patients. Health professionals can provide symptom management for cancer patients by identifying patients" needs and incorporating telehealth applications into their care plans. In this means, it can contribute to a positive change in both the physiological and psychological well-being and quality of life of cancer patients.
