Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 100 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Longterm Outcome of Photodynamic Therapy Compared With Chemotherapy Alone in Patients With Advanced Rectal Cancer
Study Start Date : August 2013
Estimated Primary Completion Date : August 2015
Estimated Study Completion Date : August 2016

Arm Intervention/treatment
No Intervention: Chemotherapy alone
Group that be scheduled to undergo chemothrapy only using FOLFOX4 protocol.
Experimental: PDT and Chemotherapy
Group that not only be scheduled to undergo chemothrapy using FOLFOX4 protocol,but also receive colonscopy-assisted PDT.
Procedure: Photodynamic therapy
Each patient to whom PDT was offered underwent a specific, detailed educational process by a dedicated team member(P.B., P.J., or K.E.), after which informed consent was obtained.Porfimer sodium (Photofrin; Axcan Pharma Inc, Quebec, Canada)was used as a photo sensitizing agent, administered intravenously at a dose of 2 mg/kg body weight 48 hours before illumination.A diode laser system (InGaAIP Laser Diode; Diomed Inc, An-dover, MA) with a maximum power output of 2000 mW and a wavelength of 633+-3 nm was used as a light source, delivered through a 3.0-m length fiber having a 2.5-cm-long cylindrical diffuser at its distal end (Pioneer Optics, Windsor Locks, CT).

Primary Outcome Measures :
  1. Survival rate [ Time Frame: one month ]

Secondary Outcome Measures :
  1. Progression-free survival [ Time Frame: One month ]

Other Outcome Measures:
  1. Quality of life [ Time Frame: one month ]
