    Surgical smoke generated during robot-assisted radical cystectomy (RARC) was hypothesized to contain bladder cancer cells.

  • 2

    A prospective study involving 28 patients found no cancer cells or mutations in surgical smoke from RARC.

  • 3

    Digital PCR analysis did not detect PIK3CA mutations in surgical smoke samples collected during the procedure.

  • 4

    Exosome analysis revealed significantly lower levels of exosomes in surgical smoke compared to control samples.

  • 5

    The study concluded that surgical smoke produced during RARC does not contain cancer cells, genes, or exosomes.
