Zusammenfassung: | Pancreatic adenocarcinoma remains one of the worst digestive cancers. Surgical resection is the main target when treating a patient with curative intent.
To assess angiolymphatic invasion as a prognostic factor in resected pN0 pancreatic cancer.
Thirty-eight patients were submitted to pancreatoduodenectomy due to head pancreatic cancer. Tumor size, margins, lymph nodes, pTNM staging, angiolymphatic and perineural invasion were described in the pathologists' reports.
Most patients were female. Overall median survival was 13 months. Gemcitabine was the regimen of choice for chemotherapy in selected patients; however, it did not improve overall survival. pR0 resection had better survival compared with pR1. Within the pN0 group, survival was significantly better in patients without angiolymphatic invasion.
Angiolymphatic invasion in N0 pancreatoduodenectomy can be demonstrated by the Hematoxylin-Eosin stain and may predict a poor prognosis factor for those patients.
Adenocarcinoma pancreático continua sendo um dos piores cânceres do aparelho digestivo. A ressecção cirúrgica é o principal objetivo quando se trata de intenção curativa.
Avaliar a invasão angiolinfática como um fator prognóstico no câncer da cabeça do pâncreas ressecado pN0.
Trinta e oito pacientes foram submetidos a duodenopancreatectomia por câncer da cabeça do pâncreas. Tamanho do tumor, margens, linfonodos, estadiamento pTNM, invasão angiolinfática e perineural foram descritos nos laudos anatomopatológicos.
A maioria foi de mulheres. A sobrevida mediana global foi de 13 meses. Gencitabina foi a droga de escolha para quimioterapia nos pacientes selecionados, entretanto não aumentou a sobrevida global. Pacientes com ressecção pR0 tiveram sobrevida global superior quando comparados com ressecção pR1. Dentro do grupo de pacientes com pN0, a sobrevida foi significativamente melhor no grupo de pacientes que não apresentavam invasão angiolinfática.
A invasão angiolinfática da duodenopancreatectomia N0 pode ser demonstrada utilizando apenas a hematoxilina-eosina e pode predizer prognóstico ruim para estes pacientes. |
