RESUMO
PURPOSE: The symptoms and survival of patients with advanced pancreatic cancer show great variability according to tumor localization. The main purpose of this study was to see for any differences between the intensity of symptoms, mainly pain, and the need for analgesic treatment in advanced pancreatic cancer patients with different (head vs. body-tail) tumor localizations. METHODS: Ninety-six patients with histologically confirmed pancreatic cancer were enrolled in the study. The patients were divided into 2 subgroups according to tumor localization: group 1 (n=50) with head tumors and group 2 (n=46) with body and tail tumors. The demographic features of the patients as well as disease stages, onset of symptoms and necessity and consumption of analgesics were recorded. Patients were followed-up until death, and survival data was also analysed. RESULTS: At the time of diagnosis, patients with body and tail tumors had more advanced disease stages compared to head tumors (p=0.006). While jaundice was the most common initial symptom in head tumors (p<0.0001), it was pain in body and tail tumors (p<0.001). Patients with body and tail tumors had more analgesics consumption as compared to those with head tumors (p=0.009). No statistically significant difference in survival was detected between the 2 groups (p>0.05). CONCLUSION: We believe that pancreatic cancer should be accepted as two diverse disease types according to tumor localization, and pain and symptom management should be organized based on this fact.
