Brief summary: Background:

For patients diagnosed with operable cancer of the gastro-esophageal junction (GEJ), the perioperative course of therapy is associated with severe deconditioning which includes weight loss and poor physical function, which are strong predictor of post-surgical complication and survival . A strong rationale exists to explore how to develop supportive interventions aimed at maintaining/improving muscle function (lean body mass and muscle strength) during the pre-surgical phase.

This study explores the safety, feasibility and efficacy of structured pre- and post-operative exercise training in patient undergoing surgery for cancer of the gastro-esophageal junction.

Subjects: Patients with histologically verified, resectable adenocarcinoma of the GEJ scheduled for treatment af Rigshospitalet, Copenhagen, Denmark.

Methods: In a case-control design, patients will be allocated to either an exercise training intervention group, or a usual-care observational group, based on geographical location. Forty patients will be included in this case-control study and allocated by geographical region as follows; 20 training intervention-cases living in the greater Copenhagen area, and 20 observational control subjects living outside the greater Copenhagen area.

All patients will undergo a total of 5 assessments during the perioperative trajectory; twice prior to surgery (baseline and pre-surgery test), three post-surgery (2 week post- and 15 weeks post-surgery, and at 1-year follow-up).

Assessments include measures of body composition by DXA scan and bioelectrical impedance analysis: systemic inflammation in fasting blood sample; quality of life by self-report questionnaires; physical function by handgrip strength and sit-to-stand test.

As optional procedures, we will collect biological tissue from tumor, muscle and fat biopsies and a 10 ml blood sample at baseline and pre-surgery test only. Also, we will collect blood samples before, during and after an acute exercise bout exercise in order to explore the acute systemic changes in exercise-regulated biomarkers.

Detailed description: BACKGROUND AND RATIONALE Patients diagnosed with operable cancer in upper gastro-intestinal (GI) tract undergo serious therapeutic procedures including invasive surgery combined with chemo- or chemo-radio therapy before (neo-adjuvant) and/or after (adjuvant) surgery. Despite recent advances, especially in surgical techniques and patient care follow-up, the population is faced with one of the worst prognosis for patients with operable staged disease, with a 5-year relative survival of 35-40%. The only possibility of long-term survival is positive surgical outcome, which includes the surgical principle of performing wide clearance, achieving a negative margin (R0 resection), and performing a radical lymphadenectomy. To this end, considerable efforts have been made in recent years optimizing the perioperative period in order to provide the patients and the surgeons with the best possible chances of achieving this surgical outcome.

Adenocarcinoma of the gastro-esophageal junction (GEJ) has increased in incidence over the last quarter century. For patients presenting with localized disease, advances in standards of care have emerged in recent years which have improved disease management. Firstly, comprehensive staging with Computed Tomography (CT), endoscopic ultrasound, diagnostic laparoscopy and fluoro deoxy glucose position emission tomography (18FDG-PET) permits exclusion of patients for curative therapy who might previously have been scheduled for resection. Secondly, evidence supports that esophagectomy is performed in high-volume hospitals by high-volume surgeons. Finally, standard neoadjuvant and adjuvant therapies are performed in most centers for patients with localized esophageal adenocarcinoma which has improved both short- and long-term cancer outcomes.

Prognostic role of Muscle Function in upper GI cancer For all upper GI cancers, including GEJ, the perioperative course of therapy is associated with severe deconditioning which includes weight loss and poor physical function. Over the last decade, strong observational evidence has emerged supporting that poor pre-surgical muscle function, defined as either low muscle mass/area (sarcopenia) or low functional strength, is a strong independent predictor of post-surgical outcomes including mortality, surgical complications and chemotherapy dose-reduction. Importantly, strong evidence across different malignancies has shown that the prognostic value of muscle function is independent from body mass, and may actually be under-reported due to sarcopenic obesity. Thus, current available therapeutic countermeasures in clinical practice, which exclusively involve nutritional interventions, may have limited potential for ameliorating the progressive muscle dysfunction during perioperative treatment for GEJ cancer.

Exercise-Oncology and Upper GI cancer Epidemiological evidence across both heterogeneous and homogeneous groups of cancer patients have shown that low physical activity level after diagnosis is associated with poor disease-specific and overall survival. Despite a general emerging interest, limited attention has been dedicated to the exploration of safety, feasibility and efficacy of structured exercise interventions in patients with upper GI cancer. However, data from recent studies suggests an unmet potential of physical exercise in these patients, with particular emphasis on the pre-surgical period.

STUDY OBJECTIVES Primary Objective

• To explore safety and feasibility of structured exercise in the pre- and post-operative phases among patients undergoing treatment for operable GEJ cancer

Secondary objectives:

* To explore the effect of perioperative exercise training on clinical (e.g. clindo-davien score, pneumonia, anastomotic leakage) physiological (e.g. muscle strength, physical function) and psycho-social (e.g. fatigue, emotional well-being, anxiety) endpoints relative to usual care.
* To explore the prognostic role of pathophysiological profile (physical function, pulmonary function, and body-composition) on post-surgical complications

Explorative objectives:

* To explore molecular adaptations of metabolism and physiology in tumor, muscle and fat samples taken before and after neo-adjuvant chemotherapy in the pre-operative phase in (a sub-group of) patients allocated to exercise training or usual care
* To explore the acute response in immune cells, hormones and cytokines in blood samples taken before, during and after a single exercise session
* Collection of blood and tissue samples for storage in bio-bank for future research.

STUDY DESIGN This prospective, regional-based case-controlled feasibility trial will include in a minimum of 40 patients, including 20 training intervention-cases who are residents in greater Copenhagen Area, and 20 usual care controls living outside the greater Copenhagen area.

Recruitment: Patients will be recruited from the department of surgical gastroenterology, Rigshospitalet, following multidisciplinary medical conference. The responsible physicians will provide oral information and present patients with the written information of the study.

Patients who are willing to participate will sign informed consent, before any study related procedures are performed. After signing informed consent, patients are scheduled for baseline assessment and will be allocated based on geographical location (home-town municipality), to one of two experimental arms:

I) Patient residing OUTSIDE the Copenhagen area, will be allocated to a usual care observation group, which includes nurse-based follow up procedures and information on life style factors (diet, smoking cessation, alcohol, and physical activity).

II) Patients residing WITHIN the Copenhagen area, will be allocated to usual care plus hospital-based aerobic and resistance training at Centre for Physical Activity Research, Rigshospitalet

Procedures will involve assessment-measures conducted a total of 5 times during the study period: twice prior to surgery (baseline and pre-surgery test), twice post-surgery (3 week post- and 15 weeks post-surgery) and at 1-year follow-up.

The following assessments will be performed:

1. Body composition by Bioelectrical Impedance
2. Fasting blood sample for analyses of plasma biochemistry (cholesterol, triglycerides, inflammatory markers, HbA1C)
3. Health related Quality of Life questionnaires
4. Physical function: Handgrip strength and sit-to-stand test.
5. Forced Expiration Volume in 1 second (FEV1)
6. Biological tissue sampling (OPTIONAL): tumor, muscle and fat biopsies and blood samples - only baseline and pre-surgery.
7. Acute Exercise Response (OPTIONAL); blood samples taken before and after a single exercise session.

ANALYTIC PLAN As a feasibility study, this trial is explorative in nature and performed primarily in order to determine whether it is appropriate to advance with a larger scaled randomized controlled trial.

Primary aim

Safety and feasibility of perioperative exercise training in patients with operable GEJ cancer

In order to evaluate the safety and feasibility of the pre- and post-surgical exercise in patients with operable cancer of the gastro-esophageal junction, incidence of serious adverse events in both groups will be determined, and adherence to exercise, assessed by number of training sessions completed in the training group.

Secondary aims

Efficacy of perioperative exercise training to improve clinical, physiological and psycho-social outcomes in patients operable GEJ cancer.

In order to determine whether exercise training has the capacity to improve study outcomes intragroup changes, and inter-group differences for study outcomes will be calculated. For this purpose a random effect analysis will be performed with repeated measures and study outcomes as dependent variables, with the covariates "group", "time" and their interaction as fixed effects, and a random effect of "patient", adjusted for baseline-score, chemotherapy regimen, and surgical procedure (conventional vs laparoscopic).

Prognostic role of pathophysiological profile in patients with operable GEJ cancer

In order to explore the prognostic role of the study assessment outcomes on key clinical endpoints: post-surgical complications, hospital stay duration and disease free and overall mortality risk over the first years after surgery, by a general linear regression models with clinical endpoints being the dependent variable, and study assessment outcomes as the independent variables adjusted for baseline-score, chemotherapy regimen, and surgical procedure (conventional vs laparoscopic). For each variable (physical function, pulmonary function, and body-composition), the predictive value of: I) the diagnostic level (prior to neo-adjuvant therapy), II) the pre-surgical level (after neo-adjuvant treatment) and III) the change score from diagnostic to pre-surgical level (during neo-adjuvant therapy) will be determined.

Dropouts and Missing Observations Patients who wish to drop-out of the study during the intervention-periods will be offered to remain in the study with regard to test-assessments. Patients who drop out prior to 'visit 2' will be replaced. For between-group analyses, all drop-outs and missing observations will be handled by the "missing at random" principle.

ETHICAL CONSIDERATIONS This study will be conducted in accordance with the regional ethical committee and the Declaration of Helsinki (1964) with its subsequent revisions. The protocol and any substantial amendments, the study patient information and consent form, as well as other relevant or requested material have been approved by the local ethics committee (Videnskabsetisk Komite) for the Capital Region of Denmark (Protocol number: H-15014904) and is reported to the Danish Data Protection Agency (Datatilsynet: RH-2016-33, I-Suite nr.: 04396) through Rigshospitalet/Capital Region of Denmark (j.nr. 2012-58-0004).

The project is expected to cause limited risks, side effects and discomfort. All procedures will be performed by experienced physicians, therapists and physiologists with relevant safety, and patients will not experience any kind of delays or complications related to treatment or control process due to participation in the project. Patients may at any time, and without justification, retract their consent.
