Introduction:
Clinical research in the field of oncology is necessary to check the safety and effectiveness of potential treatment methods and translate innovative knowledge into measurable benefits for patients as well as to introduce innovative therapies for cancer treatment. In 2019, 18.1 million new cancer cases were diagnosed worldwide.

Aim:
The purpose of this study is to assess patients knowledge and awareness of the clinical trials they participate in, as well as the quality of treatment in the clinical trial compared to standard treatment.

Material and methods:
The authors anonymous questionnaire was used to assess the state of knowledge of patients. Seventy patients in clinical trials participated in the study, 87% of whom were women, and 13% were men. The patient’s knowledge was compared with the actual state of research in the chemotherapy department, and general questions about clinical trials were asked.

Results and discussion:
Most often, patients gained knowledge about clinical trials from the attending physician (37%). As many as 79% of study participants were satisfied with the informed consent procedure. The factor that most determined the participation in the clinical trial (36%) was access to innovative therapy not available in the national healthcare system. Every fourth participant in the study was unable to determine the phase of participation in clinical trials.

Conclusions:
Based on anonymous survey results, patients who participate in clinical trials know the clinical trials essential parts. The vast majority are satisfied with the informed consent process, the availability of innovative therapies, and a clinical trial phase.
