After the first treatment, every week the patients were called and consulted by telenursing. During the next there chemotherapy treatments, Edmonton Symptom Assessment System and General Comfort Questionnaire were filled. The study ended with the fourth cycle chemotherapy. A total of six telephone calls and 3 face-to-face follow-ups were done with each of the intervention group patients. Face-to-face follow-up with patients during chemotherapy treatments lasted for about 20-30 minutes, and patients were evaluated three times in terms of symptom severity and comfort level.

During their first treatment the "Patient Identification Form" was filled and they were trained, which is the routine practice of the clinic. Patients were informed about the "Symptom follow-up form", asked to mark the symptoms and signs they experienced due to the disease and treatment in the form between the two chemotherapy treatments and to note when they experienced and how they resolved this symptom. When the patients came to the second treatment, the first follow-up of the patients was done. The investigator filled Edmonton Symptom Assessment System and General Comfort Questionnaire forms via face-to-face interviews. The "Symptom Follow-up Form" given to the patients in the previous chemotherapy treatment was collected and the same new form was given. They were requested to bring this form in their next treatment. The same protocol was followed during the third and fourth chemotherapy treatment

After the first face-to-face training, counseling on the phone was conducted every week for four cycles of chemotherapy treatment. In total, six counseling sessions and four face-to-face training sessions were conducted for each patient.

This tool is designed to assist in the assessment of symptoms common in cancer patients: pain,fatique, nausea, sadness, anxiety, insomnia, anorexia, wellbeing and shortness of breath, change in skin-nails, mucositis and numbness in hands. The patient circles the most appropriate number to indicate where the symptom is between "0" and "10". "0" is the minimum value, which means there is no change and it is a better outcome for the patient. "10" is the maximum value, means that the symptom level is the highest, which is a worse outcome for the patient.

It is used to evaluate the situation of achieving the expected comfort increase result with nursing interventions that provide comfort. The scale, which is a four-point likert type, has a total of 48 items, 24 items are positive and 24 items are negative.

The lowest value that can be taken is 1 which indicates low comfort and this is a worse outcome. The highest value 4 indicates high comfort, which is a better outcome. The response patterns of the scale, which consists of positive and negative items, are given in mixed form. Accordingly, from positive statements; high score (4p) indicates high comfort, low score (1p) indicates low comfort, while negative items indicate low comfort (1p), high score (4p) low comfort.
