Pancreatic cancer is a malignant disease with a high mortality rate and severe pain that is challenging to manage. To reduce the excruciating abdominal pain, opioids and adjuvant agents are conventionally used.
PRNCPB is a treatment of neural therapy. The number of studies assessing the effect on patients’ QoL is limited and inconsistent. With this study, we intended to address this issue.
A prospective nonrandomized study with a series of cases of unresectable pancreatic cancer was conducted.
A total number of 16 patients with severe abdominal pain were enrolled in the study all of whom had responded to combined systemic analgesic therapy inadequately and had intolerable side effects contraindicating further increase in dose. The efficacy of this invasive, palliative analgesic procedure was evaluated 35 days after PRNCPB was performed. Primary outcomes were changed in pain intensity using the VAS questionnaire. Secondary outcomes were improved in QoL using the SF-36 questionnaire. Changes in pain medications and adverse reactions were monitored.
After PRNCPB patients experienced a significant decrease ( P=0.002) in pain intensity as shown by the VAS score, and a decreased opiate demand. Their QoL scores considering effect sizes also improved ( P<0.001). No complications attributable to PRNCPB were observed during the study period. Additionally, no adverse drug reactions were observed.
Detection, observation, and reporting bias can be estimated as moderate. Selection bias was not detected.
