Longitudinal assessment of quality of life in rectal cancer patients with or without stomas following primary resection

The relation between illness cognitions and quality of life in people with and without a stoma following rectal cancer treatment

OBJECTIVES

To compare health-related quality of life, emotional functioning and illness cognitions between people with and without a stoma after rectal cancer treatment about 8 years ago and to examine the relation between illness cognitions and health-related quality of life and emotional functioning.

METHODS

Sixty-two people who had undergone abdominoperineal resection with a permanent stoma and 60 people who had undergone low anterior resection without a permanent stoma participated. Questionnaires included the European Organization of Research and Treatment of Cancer Quality of Life Questionnaire-C30, the Hospital Anxiety and Depression Scale, and the Illness Cognition Questionnaire.

RESULTS

There were no significant differences between people with and without a stoma in health-related quality of life, emotional functioning and illness cognitions. There were moderate and significant relations between the illness cognitions helplessness (negative) and disease acceptance (positive) on the one hand and health-related quality of life and emotional functioning on the other. For helplessness this relation barely differed between people with and without a stoma, but for disease acceptance this relation was stronger for people without a stoma than for people with a stoma.

CONCLUSIONS

The study showed no differences in health-related quality of life, but a stronger relation between disease acceptance and health-related quality of life for people without a stoma than for people with a stoma. If this relation is causal, people with negative illness cognitions after rectal cancer treatment might be identified and offered help.

Quality of life after rectal resection for cancer, with or without permanent colostomy

BACKGROUND

For almost one hundred years abdominoperineal excision has been the standard treatment of choice for rectal cancer. With advances in the techniques for rectal resection and anastomosis, anterior resection with preservation of the sphincter function has become the preferred treatment for rectal cancers, except for those cancers very close to the anal sphincter. The main reason for this has been the conviction that the quality of life for patients with a colostomy after abdominoperineal excision was poorer than for patients undergoing a sphincter-preserving technique. However, patients having sphincter-preserving operations may experience symptoms affecting their quality of life that are different from those with stoma-patients.

OBJECTIVES

To compare the quality of life in rectal cancer patients with or without permanent colostomy.

SEARCH STRATEGY

We searched PUBMED, EMBASE, LILACS, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Colorectal Cancer Group's specialised register. Abstract books from major gastroenterological and colorectal congresses were searched. Reference lists of the selected articles were scrutinized.

SELECTION CRITERIA

All controlled clinical trials and observational studies in which quality of life was measured in patients with rectal cancer having either abdominoperineal excision or low anterior resection, using a validated quality of life instrument, were considered.

DATA COLLECTION AND ANALYSIS

One reviewer (JP) checked the titles and abstracts identified from the databases and hand search. Full text copies of all studies of possible relevance were obtained. The reviewer decided which studies met the inclusion criteria. Both reviewers independently extracted data. If information was insufficient the original author was contacted to obtain missing data. Extracted data were crosschecked and discrepancies resolved by consensus.

MAIN RESULTS

Thirty potential studies were identified. Eleven of these, all non-randomised and representing 1412 participants met the inclusion criteria. Six trials found that people undergoing abdominoperineal excision did not have poorer quality of life measures than patients undergoing anterior resection. One study found that a stoma only slightly affected the person's quality of life. Four studies found that patients receiving abdominoperineal excision had significantly poorer quality of life than after anterior resection. Due to heterogeneity, meta-analysis of the included studies was not possible.

AUTHORS' CONCLUSIONS

The studies included in this review do not allow firm conclusions as to the question of whether the quality of life of people after anterior resection is superior to that of people after abdominoperineal excision. The included studies challenged the assumption that anterior resection patients fare better.Larger, better designed and executed prospective studies are needed to answer this question.
