Lung Cancer Screening For The Poor And Underserved: Should Routine Screening Be Performed?, Vaibhav Verma, Vladimir K. Gotlieb, Joshua Fogel, Alan S. Multz, Geeti Sharma

Publications and Research

Background: Lung cancer is a leading cause of death in United States. A recent study using low dose CT scans for screening long term smokers for lung cancer has, for the first time, demonstrated reduction in mortality, although it is not a standard of care in the community yet.

Methods: We analyzed lung cancer data for stages 0 through 4 for 1,412 individuals from, a public hospital, Nassau University Medical Center (NUMC) with patients of lower income, two private hospitals, North Shore University Hospital (NSUH) and Long Island Jewish Hospital (LIJ), with patients of higher income, with average household income …

Advances In Ultrafast Time Resolved Fluorescence Physics For Cancer Detection In Optical Biopsy, R. R. Alfano

Publications and Research

We discuss the use of time resolved fluorescence spectroscopy to extract fundamental kinetic information on molecular species in tissues. The temporal profiles reveal the lifetime and amplitudes associated with key active molecules distinguishing the local spectral environment of tissues. The femtosecond laser pulses at 310 nm excite the tissue. The emission profile at 340 nm from tryptophan is non-exponential due to the micro-environment. The slow and fast amplitudes and lifetimes of emission profiles reveal that cancer and normal states can be distinguished. Time resolved optical methods offer a new cancer diagnostic modality for the medical community.
