Relaxation and Exercise In Lymphoma Patients

This study will aim to compare the effects of an Exercise programme and a Relaxation Intervention in lymphoma patients in remission post-chemotherapy on quality of life, cardiovascular fitness, exercise tolerance, muscle strength, psychological status, social well-being and biological markers.

Subjects will be recruited from a specialist lymphoma clinic in South West London and randomly allocated to an exercise or a relaxation home programme. The study aims to determine the more effective intervention of the two in relation to the outcome measures.

The investigators anticipate that the interventions will result in less adverse events and improved quality of life and physical fitness, and subjects will require less medication, less counseling and cancer nurse specialist care, leading to leading to a reduction in hospital and surgery attendances.

Significant improvements have been made in the survival rates in cancer patients. Due to factors such as screening and earlier detection of cancer and advances in treatment, cancer today is a curable disease for many. However, cancer survivors are at a significantly increased risk of morbidity and adverse effects due to treatment exposures. Commonly reported consequences of cancer treatment include fatigue, pain, depression, anxiety, reduced performance status and decreased quality of life Hence cancer today is considered more as a chronic illness, and there is increasing research being carried out on cancer survivorship and recommendations for survivorship care pathways to include interventions to enhance both physical and psychosocial functioning in cancer survivors.

Previous studies have demonstrated that both exercise and interventions such as relaxation have a positive effect on both physical and psychosocial complaints of cancer survivors. These interventions are carried out in different ways, have different requirements and perceptions of the two can also be very different. No trial to date has been carried out comparing the effects of these interventions on the quality of life in cancer survivors. Furthermore, majority of the above research has been carried out on the most prevalent cancers including breast cancer, prostate cancer and colorectal cancer, and several authors have called for future research to focus on other understudied survivor groups, including haematologic cancer sites. This study aims to compare the effect of exercise and relaxation interventions on quality of life in lymphoma survivors.

The aim of the present study is to compare the effects of an Exercise Intervention Program with a Relaxation Intervention in a sample of lymphoma patients in remission post-chemotherapy.

Eligible subjects will be randomised to one of two arms - either an exercise or a relaxation arm. Both arms comprise of a home programme of their intervention (either exercise or relaxation) for half an hour, carried out three times a week. Subjects are assessed using the primary and secondary outcome measures at baseline, midway (6 weeks) and at the end of the intervention (12 weeks). It is hypothesised that a 12 week training programme of both exercise and relaxation would improve the quality of life of lymphoma survivors, however the exercise programme would result in a significantly greater improvement than relaxation. The null hypothesis would state that there would be no significant difference between exercise or relaxation groups following a 12 week training programme in lymphoma survivors.

The aims of the study are as follows:

Primary aim

To compare the effectiveness of Exercise with Relaxation in the improvement of overall wellbeing and quality of life using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30).

Secondary aims

To determine whether these interventions result in:

* Improved cardio-respiratory fitness (resting HR and BP) and pulmonary function (spirometry)
* Improved fitness and exercise tolerance using the 6 Minute Walk Test
* Improved emotional and functional confidence as measured by the Health related quality of life questionnaire Functional Assessment of Cancer Therapy Lymphoma version (FACT-Lym)
* Decreased anxiety and depression levels using the Hospital Anxiety and Depression Scale (HADS)
* Changes in haematology (haemoglobin, immunoglobulins, white count) and biochemical (serum albumin, corrected calcium, creatinine) parameters
* Compare the results of the above outcome measures between the two interventions
* Analyse subject perceptions of interventions in focus groups
