ARTICLE HIGHLIGHTS
Research background
Study with 14 patients, operated in a single center, regardless of the size of the tumor, obtained Margins R0, disease-free survival in 100% of cases, with a follow-up longer than 5 years.
Research motivation
Surgical treatment is the main pillar of cure for solid papillary neoplasm of the pancreas. The challenge is to improve access to imaging exams, screening programs and surgeons specialized in pancreatic surgery. The importance is in early diagnosis, greater chance of R0 surgery with less resection of other structures and consequently greater survival.
Research objectives
Show that solid pseudopapillary neoplasms, even when in large volumes and with the need to dry other noble structures, such as large vessels, has the possibility of cure in surgery. We were able to demonstrate in this study, with R0 surgeries and evidencing deonca-free survival and quality of life.
Research methods
Retrospective study with analysis of a prospectively filled database.
Research results
This study was made up of female patients in its entirety, corroborating the literature on being a more frequent neoplasm in women. Approximately 85% asymptomatic, incidental discovery. In our series, we have seen an increase in cases since 2012. Perhaps due to greater accessibility to imaging methods. The fact that women have specific programs for women’s health with periodic examinations and screening, may contribute to the discovery of tumors such as Solid papillary neoplasm of the pancreas in asymptomatic patients, and that we are facing an underreported neoplasm, but it is evident that we need more studies to affirm this.
Research conclusions
One theory would be that of an underdiagnosed neoplasm.
Research perspectives
Follow-up of operated patients to assess the natural history of the disease.
