Dr. Carp studies the effects of surgical practices on cancer outcomes, particularly focusing on how many lymph nodes are removed during surgeries for cancers of the colon and lung. He has discovered that removing a sufficient number of lymph nodes can significantly lower the risk of death for patients. In breast cancer treatment, he investigates cryoablation, a method that freezes tumors, finding it to be an effective non-surgical option for certain early-stage cancers. His work not only aims to improve surgical techniques but also emphasizes adherence to quality measures in hospitals to ensure better patient survival.
Key findings
In a study on colon cancer, compliance with a guideline requiring the removal of at least 12 lymph nodes improved from 52.8% to 69% over time, leading to better survival rates for patients at compliant hospitals.
Patients with early-stage non-small cell lung cancer who had at least 10 lymph nodes removed during surgery experienced a 12% lower risk of dying than those with fewer than 10 lymph nodes removed.
Cryoablation successfully eliminated cancer in 76% of treated tumors, with imaging tests showing an 81% accuracy rate in detecting remaining cancer.

The effect of Fe3+ ion on benzylpenicillin in micellar and nonmicellar aqueous solutions.
1996
Journal of pharmaceutical and biomedical analysis
Carp N, Tufoi V, Carp M, Aldea V, Badescu V
Plain English This study examined how Fe3+ ions affect the breakdown of benzylpenicillin, a common antibiotic, in both regular water solutions and special micellar solutions. Researchers found that the breakdown of the drug occurs faster when Fe3+ ions are present, with certain concentrations leading to a slower reaction rate, and a new complex that likely formed during this process was identified as Fe2BP4(OH)2. This is important because it might explain why long-term use of penicillin can sometimes result in anemia in patients.
