In this article,we apply blow-up analysis to study pointwise a priori estimates for some p-Laplacian equations based on Liouville type *** newly developed analysis techniques,we first extend the classical results of interior gradient estimates for the harmonic function to that for the p-harmonic function,i.e.,the solution ofΔpu=0,x∈Ω.We then obtain singularity and decay estimates of the sign-changing solution of Lane-Emden-Fowler type p-Laplacian equation-Δp^(u)=|u|^(λ-1)u,x∈Ω,which are then extended to the equation with general right hand term f(x,u)with certain asymptotic *** addition,point wise estimates for higher order derivatives of the solution to Lane-Emden type p-Laplacian equation,in a case of p=2,are also discussed.

To the Editor: Pancreatic cancer is the fourth leading cause of cancer mortality in the United States [ 1, 2 ]. Risk factors of pancreatic cancer include smoking, family history of chronic pancreatitis, advanced age, male, diabetes mellitus, and obesity [1]. Most of patients have no obvious symptoms in the early stage, and are often diagnosed in the late stage and accompanied by invasion of surrounding tissues and distant metastasis, such as local lymph nodes, liver, lung and peritoneum [ 1, 3 ]. Therefore, the prognosis is poor.
