Although chemoradiotherapy (CRT) is one curative treatment option for patients with esophageal squamous cell carcinoma (ESCC), local failure after CRT remains a major problem for patients’ curability. The aim of this study was to evaluate the efficacy and safety of photodynamic therapy (PDT) as a salvage treatment for local failure. From August 2007 to March 2012, 193 consecutive ESCC patients were treated with definitive CRT in Kyoto University Hospital. Eighteen of the patients with T2 or earlier T-stage local failure after CRT underwent salvage PDT. After the salvage PDT, 11 patients (61.1%) achieved a complete response at the primary site. Over a median follow-up period of 28.3 months, the 1-year survival and progression-free survival rates were 77.8% and 38.9%, respectively;and the 2-year survival and progression-free survival rates were 60.6% and 33.3%, respectively. Adverse events were mild esophageal stricture in seven (38.9%), esophageal obstruction because of necrotic tissue in nine (50.0%), and photosensitivity in three (16.7%) patients. There were no severe complications or treatment-related deaths. Salvage PDT may be a promising treatment option for the patients with a local residual or recurrent tumor after CRT for ESCC when the lesion is suspected to be in T2 or earlier.

Particle breakage is a common occurrence in granular systems when the external stress exceeds the individual particle strength.A large number of experimental evidences suggested that particle breakage may significantly influence the soil *** the case of pile foundations,the subsoil below the pile tip experiences considerable high stress and consequently prone to *** to the lack of sufficient understanding on particle breakage mechanism,there is currently no consentaneous theoretical background for particle breakage analysis during the pile penetration *** study aims to clarify the location of particle breakage and its evolving characteristics with the aid of acoustic emission(AE)source location *** spatial distribution of AE hypocenters is interpreted to be associated with the mechanism of particle *** showed that the AE sources were not uniformly distributed,but concentrated within certain zones below the pile *** AE concentration zone was pushed downward with the advancing pile tip,and its distance from the real time pile tip position decreased after certain depth of pile *** location of particle breakage interpreted from AE source location was verified with posttest excavations and the insights on the particle breakage evolution zone were further discussed.
