From: Oral cancer patients experience mechanical and chemical sensitivity at the site of the cancer
Oral cancer patients report pain at the site of the cancer in response to von Frey fibers. The MPT was defined as the geometric mean of the suprathresholds and infrathresholds. The geometric mean ± geometric SD is indicated in red. Open circles are arbitrary values indicating the four patients who did not report pain in response to any fiber including the largest diameter fiber, 6.65 (300 g). The black dotted line indicates the force corresponding to the maximum diameter fiber 6.65 and the red and blue dotted lines, the minimum and maximum measured MPTs in cohort #1
