The FOCCUS Study: "Focusing on Cancers Chemotherapys' Untreated Symptoms"

- Brief Summary
The aim of the study is to identify how often gastrointestinal problems interfere with quality of life as a result of treatment for cancer with chemotherapy. We also want to identify the causes for these symptoms and see if simple treatments used for other gastrointestinal conditions could make chemotherapy an easier experience. Chemotherapy for cancer can be hard work for the patient. Often it makes them feel tired. Not infrequently, it can cause a whole range of physical side effects. Probably the most common side effects are those affecting the stomach and bowels. Vomiting used to be a major problem with chemotherapy but research discovered a whole series of new treatments so that severe vomiting from chemotherapy is rarely a problem today. However, patients can develop a whole series of other symptoms during chemotherapy, for example, bloating, wind, diarrhoea, needing to rush to the lavatory and opening the bowels very frequently. The causes for these symptoms have hardly been studied even though they sometimes affect people quite badly. In our specialist gastrointestinal clinic at the Royal Marsden Hospital, over the last 12 years, we have pioneered new methods for dealing with symptoms which affect the bowel after radiotherapy. We would like to extend these methods to people having chemotherapy. We have identified several easily treatable causes for these symptoms after radiotherapy, which previously were often ignored. We believe that some of these causes also occur in people having chemotherapy and if we knew how often they do occur we could focus on improving treatment for affected people. We plan to find out how often 40 stomach and bowel symptoms occur during chemotherapy. In people who are troubled by any or some of these symptoms we will arrange simple series tests which could sort out why these symptoms occur and we will record how they respond to treatment.
- Detailed Description
Chemotherapy (CT) remains an integral part of treatment for many types of cancer often in combination with surgery and/or radiotherapy. In the year March 2011 to April 2012, 1807 patients were referred to the Royal Marsden Hospital (RMH) Gastrointestinal Unit with a new gastro intestinal (GI) cancer of whom 709 were treated with chemotherapy alone or in combination with other long term outcome. GI symptoms are common in patients receiving chemotherapy. They may arise from the tumour, but may also result as a side effect of treatment. They include anorexia, borborygmi, bloating, constipation, diarrhoea, dysphagia, early satiety, frequency of defaecation, incontinence, mucus discharge, nausea, nocturnal defaecation, pain, reflux, regurgitation, steatorrhoea, tenesmus, urgency of defaecation, vomiting, weight loss and wind. Frequently, such symptoms have a significant impact on patients' quality of life. They may also interfere with the delivery of treatment prompting cessation of therapy or dose reduction resulting in sub optimal dosage with a potential impact on morbidity and mortality. Whilst clinicians have long focused on the management of vomiting and pain in cancer patients, less attention has been paid to the incidence, severity or optimal management of other GI symptoms. If the cause of these symptoms can be identified, then appropriate investigations and treatments can be prescribed. The GI Unit has successfully investigated and treated patients with symptoms emerging after radiotherapy. This experience has enabled the team to develop an algorithm for facilitating the investigation and treatment of cancer therapy induced symptoms. The algorithm has recently been shown to be effective in the management of patients with radiation induced bowel injury . In particular, it enables the rapid identification of required investigations and improves the management of symptoms that might otherwise be mislabeled as inevitable consequences of treatment. Five easily treatable causes for GI symptoms have so far been identified:
* Small bowel bacterial overgrowth
* Carbohydrate malabsorption
* Bile acid malabsorption
* Gastric bile reflux
* Pancreatic insufficiency
It is likely that additional causes such as viral infections (eg cytomegalovirus) are more frequent in patients undergoing chemotherapy than currently appreciated.
