CHICAGO — Patients with metastatic cancer who used a web-based tool to regularly report symptoms while receiving chemotherapy reported a higher quality of life, had fewer emergency room visits and lived a median of 5 months longer than those who did not use the tool, according to a randomized clinical trial presented during the plenary session of the ASCO Annual Meeting.

The intervention — which enables patients to report symptoms in real time and trigger alerts to clinicians — can have major benefits for patients, according to researchers.

“This is a very simple tool that is going to be familiar to many people who already are accustomed to using all kinds of online means of communication,” Ethan M. Basch, MD, MSc, FASCO, professor of medicine at Lineberger Comprehensive Cancer Center at University of North Carolina, told HemOnc Today. “This is an opportunity for us as oncologists to integrate this kind of tool — ubiquitous in other sectors — into the way we practice to better engage our patients and improve communication. And, as it turns out, it improves clinical outcomes as well.”

From 2007 to 2011, Basch and colleagues enrolled 766 patients (median age, 61 years; 86% white; 58% women; 22% with less than a high school education) with advanced solid tumors who were receiving outpatient chemotherapy. Cancer types included genitourinary (32%), gynecologic (23%), breast (19%) and lung (26%).

Researchers randomly assigned patients to an intervention group that reported symptoms via tablet computers, or to a usual-care group whose symptoms were monitored and documented by clinicians. Patients in the usual-care group discussed symptoms during visits with oncologists and were encouraged to telephone the office between visits if any concerning symptoms arose.

On a weekly basis, patients in the intervention group reported on 12 common symptoms experienced during chemotherapy — including appetite loss, difficulty breathing, fatigue, hot flashes, nausea and pain — and graded them on a 5-point scale. Researchers developed the web-based tool, Symptom Tracking and Reporting (STAR), for research purposes, and it is not commercially available.

“Symptoms such as nausea, pain and fatigue are common among patients with metastatic cancer but, unfortunately, they often go undetected by doctors and nurses until they become severe and physically debilitating,” Basch said. “This is because, between visits, patients are often hesitant to call the office until problems become severe. We hypothesized that having patients record their own symptoms using an online system, with this information conveyed to their clinicians, would prompt those clinicians to intervene earlier and improve symptom control and downstream health outcomes.”

Patients could report the symptoms remotely from home or at the doctor’s office during oncology or chemotherapy visits, using tablet computers or computer kiosks. Doctors received symptom reports during visits, and nurses received email alerts when patients reported severe or worsening symptoms.

All patients in the intervention group, including those with little prior experience using the Internet, were willing and able to regularly report their symptoms via the web throughout chemotherapy. Nurses took immediate clinical actions more than 75% of the time when patients reported severe or worsening symptoms.

Compared with patients who received usual care, patients who used the web tool to self-report symptoms had longer median OS (31.2 months vs. 26 months). In the multivariable model, these results remained statistically significant (HR = 0.83; 95% CI, 0.69-0.99).

“We know from prior research that, unfortunately, we as clinicians are unaware of up to half of our patients’ symptoms,” said Basch, who was practicing at Memorial Sloan Kettering Cancer Center when the study was conducted. “It was not initially surprising that engaging patients to self-report their symptoms and sending alerts to providers to make our teams more aware would improve symptom control and even quality of life. In fact, we saw that 31% of patients had better quality of life.

“What was more surprising was that emergency room visits were reduced by 7%, probably because we were catching things early, before they became problems, and it was surprising they were able to stay on chemotherapy an average of 2 months longer, probably because we were controlling symptoms,” Basch added. “But, ultimately, what was most surprising was the OS benefit, simply because patients were self-reporting their symptoms and we knew about it.”

Researchers’ findings are being confirmed in a larger clinical trial, which uses an updated, more user-friendly online tool that works on both personal computers and mobile devices. The study is being conducted in community practices across the United States.

“As oncologists, we all feel we could communicate better,” Basch said. “We’re nostalgic for the days of being community doctors, when we could go to patients’ homes and know their families. All of these barriers have been constructed that keep us separated from our patients, and this intervention allows us to get a little closer.” – by Chuck Gormley
