Sociodemographic and clinical correlates of treatment efficacy expectations in patients with cancer: a prospective multicenter cross-sectional study from the NEOTEAM-SEOM group
This prospective multicenter study of 755 Spanish cancer patients found that high treatment efficacy expectations were common (82.5%) and independently associated with female sex, lower socioeconomic vulnerability, and less advanced disease, though the modest predictive power of these factors suggests clinicians should directly elicit expectations rather than infer them from patient characteristics to optimize shared decision-making.

When a person receives a diagnosis of cancer, the path forward often involves a conversation about treatment. This conversation is not just about the drugs or procedures themselves, but about what the patient believes those treatments will achieve. In the world of medicine, this belief is known as "treatment efficacy expectation." It is the patient's internal answer to the question: "Will this help me?" It encompasses hopes for a cure, the desire for a better quality of life, the relief of symptoms, and the fear of severe side effects. This concept is distinct from simply knowing the statistics of the disease; it is about the personal anticipation of how the treatment will work. These expectations matter deeply because they influence whether a patient agrees to a therapy, how well they stick to the plan, and how they communicate with their doctors. If a patient expects a miracle while the doctor offers a management strategy, or if a patient fears the worst while the doctor offers hope, the partnership can falter. Understanding what shapes these expectations is crucial for building trust and making decisions that truly fit the person in the chair.
A team of researchers across Spain set out to understand these expectations in a large, real-world setting. They gathered a group of 755 adults with various types of non-blood cancers from fifteen different university hospitals. These patients were all about to start a new systemic treatment, meaning a therapy that travels through the whole body, such as chemotherapy, immunotherapy, or targeted drugs. Before the first dose was given, the researchers asked the patients to fill out a simple questionnaire. The questions were direct: did they expect the treatment to cure their cancer? Did they expect it to improve their quality of life? Did they expect it to relieve their symptoms? And did they expect it to cause severe side effects? The researchers combined these answers into a single score to see who held high, favorable expectations and who held lower or more moderate ones. They then looked at the patients' medical records and personal backgrounds to see if specific factors, like age, gender, how advanced the cancer was, or how much the patient felt involved in the decision, could predict these expectations.
The results revealed that high expectations were very common. More than four out of five patients, specifically 82.5 percent, reported having high expectations for their treatment. This means the vast majority of people in the study believed their upcoming therapy would bring significant benefit. However, the study also found that these beliefs were not random; they were linked to specific characteristics of the patient and their disease. The researchers discovered that women were more likely to report high expectations than men. Similarly, patients whose cancer was in an earlier stage, or who had a disease that could be surgically removed, held higher expectations than those with advanced, unresectable cancer that could not be cured. Socioeconomic factors also played a role; patients with lower levels of social vulnerability—measured by factors like having a partner, being employed, and having more education—tended to have more favorable expectations than those with higher vulnerability.
Interestingly, the study ruled out several factors that one might assume would be important. The researchers found that a patient's age did not independently predict their expectations; both younger and older adults held similar levels of hope. The amount of inflammation in a patient's blood, a known marker for how aggressive a tumor might be, did not change what the patient expected. Perhaps most notably, the study found that how much a patient felt they participated in the decision-making process did not change their expectations. A patient who felt deeply involved in choosing their treatment was no more or less likely to have high expectations than one who felt less involved. This suggests that feeling heard during a consultation does not automatically translate into a specific belief about the treatment's outcome.
The study authors were careful to note what their findings do not prove. They did not measure whether these high expectations were actually accurate or realistic compared to what the doctors knew about the disease. They simply measured what the patients believed. Because the study was a snapshot in time, taken before treatment began, it cannot show how these beliefs change as the disease progresses or as treatment takes effect. The statistical model they built could only explain a small portion of why one person had high expectations and another did not. This means that while gender, disease stage, and social circumstances offer some clues, they cannot predict what a specific individual will think. The vast majority of the reasons behind a patient's expectations remain unexplained by these simple factors.
Ultimately, the work suggests that doctors cannot guess a patient's hopes based on their age, their lab results, or even how much they talk during the visit. The most reliable way to understand what a patient expects is to ask them directly. The study highlights that while certain groups of people tend to share similar outlooks, the inner world of a patient's hope is complex and unique. By listening to these expectations rather than inferring them, medical teams can better tailor their communication, ensuring that the conversation about treatment aligns with what the patient truly needs and understands, preserving hope while grounding the discussion in reality.
