Dear Editor,In the United States,pancreatic cancer is considered the fourth most common reason for cancer-related deaths;over 53%of patients are diagnosed at end-stage with a 5-year survival rate of less than 3%[1].Incomplete removal of all cancerous cells generally leads to local recurrence of pancreatic cancer[2].Thus,the detection of tumor margin status plays an essential role in the complete resection of pancreatic *** of the existing imaging modalities,like computed tomography and magnetic resonance imaging,are primarily used for preoperative planning;these modalities also have issues of bulky equipment,radiation concerns,and slow imaging speed[2].Thus,these modalities can neither provide an intraoperative diagnosis of cancer with high sensitivity and specificity nor be used to define tumor margins[3].

Oral antibiotics are often prescribed to prevent infection after implant surgery;however, only a small fraction of the antibiotics can reach the implants. Thus, there are concerns about overusing antibiotics. We designed and fabricated porous implants with interconnecting 3D structures (I3D) and hypothesized that such I3D structures could serve as a depository for antimicrobial agents to prevent infection locally. The implants were either treated with antibiotics or coated with silver nanoparticles (AgNPs) by electrodeposition to test this hypothesis. The antimicrobial assay was conducted, and bacterial growth zones of inhibition (ZOIs) were monitored. Overall, I3D implants resulted in larger ZOIs than did the solid implants, and the center I3D (cI3D)-implant produced the largest ZOI. In the antibiotic treatment testing, the diameters of ZOIs of the solid implant vs. I3D implant were about 14 mm vs. 15 to 18 mm on day 2;however, the diameter quickly reduced to 9 mm on day 3 and 5 mm on days 6 and 8 for the solid implant, while no obvious change of the zone was seen for I3D implants. For the AgNPs coated implants, the ZOIs for the I3D implants were generally greater than the solid implant over four weeks of incubation. A significantly larger ZOI (~1 - 2 mm larger on average) was seen for AgNPs coated I3D implants at 0.1 V - 0.01 M, 0.3 V - 0.01 M, and 1.5 V - 0.01 M treatments compared to AgNPs coated solid implants. Given that we have previously shown that I3D implants can reserve chemoattractants to recruit stem cells to enhance osseointegration, we conclude that implants with the I3D structures could be beneficial not only for osseointegration but also in preventing infection.
