Brief Summary

With the increase in the incidence of cancer in our country and the world, the number of breast cancer survivors is increasing rapidly due to the development of early diagnosis and treatment methods. One of the main problems in breast cancer survivors is lymphedema. Breast cancer-related lymphedema is a condition that can be treated when detected early, but has a very low success rate when detected in advanced stages. Therefore, the prevention and early detection of breast cancer-associated lymphedema is very important. In this project, it is aimed to prevent breast cancer-related lymphedema with the mobile application to be developed and to detect the volume increase in the arm before clinical findings with an arm volume measurement device that will work with this mobile application. The project consists of two main steps; (a)development of the arm volume measuring device and mobile application (b)evaluation of the effectiveness of the products. Five components will be involved in the development of the mobile application. These components are; (I)exercise, (II)education, (III)coping mechanisms, (IV)arm volume measurement/records, and (V)reminder for exercise, measurement, and follow-ups. Exercise videos will include stretching exercises for the shoulder and arm area as recommended in the guides. The training content will be created in line with the guides and opinions will be taken from an expert panel. In support of coping mechanisms, existing problem areas in people will be determined with a qualitative study. People who have gone through a similar process in the past will be asked about the coping strategies they have developed for these problem areas. Themes obtained from patients who have gone through a similar process in the past (lymph node dissection due to breast cancer) and suggestions of the guidelines will be presented in the mobile application. In arm volume measurement, a wearable technology product to be designed in the form of an arm cuff and strain sensors to be placed on the arm will detect the increase in arm circumference.

Themes obtained from patients who have gone through a similar process in the past (lymph node dissection due to breast cancer) and suggestions of the guidelines will be presented in the mobile application. In arm volume measurement, a wearable technology product to be designed in the form of an arm cuff and strain sensors to be placed on the arm will detect the increase in arm circumference. After measuring the arm circumference with the sensors located every five centimeters, the arm volume will be calculated with the cylindrical volume calculation method. When there is an increase of 5% or more in the arm of the individual (preclinical lymphedema), a notification will be sent to the person and his/her physician via the mobile application. The person will also be able to follow the past measurement results via the mobile application. Evaluation of the efficacy of the product will be based on a pilot randomized controlled trial, a reproducibility study, and patient feedback. This product to be developed will provide a new arm volume measurement method that will reduce patients' hospital admissions and will contribute to the prevention and early detection of lymphedema.

Outcome Measures

Primary Outcomes (3)

• Disability of Arm, Shoulder and Hand- DASH

  The first section contains 30 questions, of which 21 questions assess difficulties experienced in activities of daily living, 5 questions assess symptoms and 4 questions assess social functioning, work, sleep and patient confidence. This section determines the patient's function/symptom status and is referred to as the DASH-FS.

  It will be applied to the participants at baseline, as well as at the 25th month and 33th month follow ups.

• Adult Life Quality Scale in Cancer Survivors

  Consisting of 47 items and 12 sub-dimensions, the items in the scale are answered in 7-point Likert type. The scale consists of two parts: general and cancer-specific quality of life. Of these 12 sub-dimensions, 7 are related to general quality of life and 5 are related to cancer-specific quality of life.

  It will be applied to the participants at baseline, as well as at the 25th month and 33th month follow ups.

• Positive Affectivity, Negative Affectivity Scale - PANAS

  The 10 affect states of Excited, Strong, Enthusiastic, Proud, Alert, Inspired, Determined, Active, Concerned, and Attentive measure positive affect; the 10 affect states of Distressed, Unhappy, Guilty, Frightened, Hostile, Irritable, Embarrassed, Nervous, Agitated, and Scared measure negative affect.

  It will be applied to the participants at baseline, as well as at the 25th month and 33th month follow ups.

Study Arms (2)

Intervention Group

EXPERIMENTAL

This group will be provided with the mobile application and volume measurement device. The planning for hospital visits will be organised at the same frequency in both groups. All individuals will be followed up for three months. The same measurement tools will be applied to both groups before and after the application.

Device: Mobile application and an arm volume measurement device

Control Group

NO INTERVENTION

This group will receive routine care at the clinic.The planning for hospital visits will be organised at the same frequency in both groups. All individuals will be followed up for three months. The same measurement tools will be applied to both groups before and after the application.

Interventions

Mobile application and an arm volume measurement device DEVICE

The intervention consists mainly of two steps; (a) development of a mobile application with an arm volume measurement device (b) evaluation of the effectiveness of the products. Five components will be involved in the development of the mobile application. These components are; (I) exercise, (II) education, (III) coping mechanisms, (IV) arm volume measurement/recording and (V) appointment, exercise and measurement reminder panel. Exercise videos will include stretching exercises for the shoulder and arm as recommended in the guidelines
