The goal of this observational-retrospective study is to learn about the long-term effects of a lifestyle intervention inclusive of dietary counselling and physical activity advice, on body weight in female breast cancer survivors who took the intervention in previous years compared to those who did not take it.
The main question it aims to answer is:
Does a long-term lifestyle intervention help to control body weight 5 years after breast cancer diagnosis? Participants are asked to answer online survey questions about their anthropomethry, clinical conditions, socio-economical status, dietary habits, physical activity levels, quality of life, sleep quality and pshycological distress.
Investigators will use data from 428 women with a 5-yr primary diagnosis of BC (stages I-III at ages ≥30 <75 anni). Half of this sample (N=214) who followed integrated lifestyle treatment of behavioral modification of diet and physical activity conducted by Pascale Institute since 2016; the other half (N=214) will be patients who were eligible to participate but did not for logistic reasons.
The present study aims to enroll 428 women with prior primary diagnosis of breast cancer. Half of the patients (N = 214) had previously followed the lifestyle treatment of DEDiCa trial on the modification of eating and physical activity habits (Eudract n. 2015-005147-14) conducted by the Oncologic Institute Pascale in Naples (Italy) since Nov 2016; the other half of the patients were 214 who had refused to participate in the aforementioned trial for reasons unrelated to serious health conditions or progression of the disease.

| Lifestyle | The cohort incluedes women (N=428) with a 5-year primary diagnosis of breast cancer eligible to participate in a diet and exercise trial (DEDiCa) in the previous years. Half of them actively participated in the trial and half did not for reasons other than health related issues. Those who consent to participate to the current observational study completed a series of questionnaires. |

| Measurement of body weight in kilograms | The primary objective of the study is to evaluate whether an integrated lifestyle cancer treatment (L-INT) with nutritional and physical activity counseling, within the first year of diagnosis of histologically confirmed primary breast cancer, can result in better control of body weight (measured as BMI classes) after 5 years from diagnosis compared to those who had not adhered to integrated lifestyle treatments (no-INT). | Baseline |
| Measurement of body height in meters | The primary objective of the study is to evaluate whether an integrated lifestyle cancer treatment (L-INT) with nutritional and physical activity counseling, within the first year of diagnosis of histologically confirmed primary breast cancer, can result in better control of body weight (measured as BMI classes) after 5 years from diagnosis compared to those who had not adhered to integrated lifestyle treatments (no-INT). | Baseline |

| Units on a Scale adherence to the Mediterranean diet. | The secondary objectives aim to evaluate the current adherence to the Mediterranean diet and the following variables: disease-free survival, new onset of chronic diseases (second cancer, diabetes, cardiovascular events, osteoporosis/bone fractures), quality of life including psychological distress and sleep quality. As an exploratory secondary objective, on a subgroup (N = 40), plans to study the microbiome of breast cancer tissue stored in the biobank of the Pascale Institute, to relate it to the characteristics of the disease and the patients' lifestyle. |

An exploratory secondary objective of the study, in a subset of the sample (N=40), includes an investigation of the microbiome of the breast tissue extracted during breast cancer surgery. This analysis is useful to determine breast cancer tissue microbiome and potential associations with different lifestyle.
