The International Neuroendocrine Cancer Alliance (INCA) and Novartis presents the quality-of-life results from the first global survey of patients with neuroendocrine tumors (NETs), a rare type of cancer1.

Nearly 2,000 patients from 12 countries completed the survey, which was a collaborative effort between INCA and Novartis. The results were presented at a medical meeting and provide compelling data documenting the impact of NETs on people living with this disease1. These quality-of-life findings are the first in a series of results from the survey being released in conjunction with Worldwide NET Cancer Awareness Day (WNCAD), November 10.

  • Results show 92% of patients made lifestyle modifications as a result of their NET, including changes to diet, work, physical activities and social life1
  • Among those currently working nearly half had to take days off as a result of their NET, and among those not working 82% had to stop due to their NET1
  • Survey is a collaboration between Novartis and International Neuroendocrine Cancer Alliance; initial set of results released in conjunction with NET Cancer Day


Quality of life is negatively affected

The survey results showed that the vast majority of respondents (71%) reported their quality of life was negatively affected by their disease and up to 92% made lifestyle changes as a result of their NET1. Specific areas impacted by NETs include work, emotional health and lifestyle1.

“This is the first time the NET patient experience has been quantified on a global level, and it confirms for us the devastating impact this rare cancer can have on patients’ lives,” said Teodora Kolarova, INCA President. “We hope these survey findings help give people with this type of cancer a voice, and educate the public and healthcare professionals about the personal side of this disease.”

Among those who were currently working (39% of respondents), nearly half (49%) had to take days off work due to their NET1. For respondents who were not working or were unemployed because of medical disability (22%), the majority had stopped working as a result of their NET (82%)1. Approximately half of the respondents reported an increase of their time (52%) and the amount of money (51%) spent on medical appointments1.

The survey also measured the toll that having a NET can have on patients’ emotional health and lifestyle. Most respondents (60%) noted that their emotional health had been affected “a moderate amount” or “a lot” by their NET. Additionally, more than half worry about the uncertainty of their future (58%), with 52% reporting having to deal with significant stress and anxiety levels1. Nearly two-fifths of respondents (39%) feel confused about the management of their disease1. Patients also reported that their NET affects their overall energy levels (70%), diet (58%), ability to participate in leisure activities (54%) and social life (43%), and limited their physical activities (49%), with many (43%) unable to participate in activities they used to enjoy1.


Awareness about NET Cancer is very limited

Since NETs are uncommon, awareness about the disease is very limited. Neuroendocrine tumors arise in different tissues and organs throughout the body that contain neuroendocrine cells; most are found in the gastrointestinal (GI) tract, lungs and pancreas, and they are categorized as symptomatic (functional) or asymptomatic (non-functional)2,3,4,5. Signs and symptoms of NETs include, but are not limited to: flushing, diarrhea, intermittent abdominal pain, wheezing, coughing and bloody sputum6,7. Nonfunctional NETs do not produce any hormonal symptoms and can be more difficult to diagnose5. Even symptomatic patients are often misdiagnosed because their symptoms can be similar to those of other diseases and conditions (e.g., colitis, irritable bowel syndrome and asthma)7. For these reasons, NETs are often initially diagnosed at an advanced stage5.

“This collaboration between INCA and Novartis has yielded tremendous information about the NET patient experience around the world,” said Grace Goldstein, immediate past president, INCA. “The survey shows how difficult it can be to live with a NET, and we hope that these insights can help drive conversations and action to better understand and meet the needs of NET patients everywhere.”

The Novartis collaboration with INCA is part of the company’s longstanding commitment to improving knowledge and management of NETs, engaging with patient groups to better understand the patient experience and helping the patient community to raise its voice. Results from the survey related to quality of life were presented at the North American NeuroEndocrine Tumor Society (NANETS) symposium in Nashville, TN, USA, October 10-11, 2014.
