Brief Summary:
The long-term results of several large-scale prospective randomized trials that compared laparoscopic-assisted and open colectomy for colon cancer were published in the past decade. The oncologic outcomes were nearly similar in patients who underwent laparoscopic or open surgery. In Japan, the Japan Clinical Oncology Group (JCOG) conducted a randomized trial to compare oncological outcomes between patients who underwent laparoscopic or open surgery for advanced colon cancer and recto-sigmoid cancer. However, the exclusion criterion were concerning tumor site in transverse and descending colon. The reason of exclusion was that laparoscopic procedure was difficult in transverse and descending colon cancers. However, laparoscopic surgery for transverse and descending colon cancer was performed clinically. We conducted a randomized trial that compared laparoscopic surgery and conventional open surgery in in transverse and descending colon cancer. The purpose of the present study was to clarify the safety and feasibility of laparoscopic surgery on in transverse and descending colon cancer patients.

Primary Outcome Measures :
  1. Early complication rate [ Time Frame: within the first 30 days after surgery ]
    Early complication is defined as a complication that occured between the finish of the surgery and postoperative day 30.

Secondary Outcome Measures :
  1. Recurrence-free survival [ Time Frame: 5 years ]
    All death and recurrence of colon cancer is defined as an event of recurrence-free survival.

  2. Overall survival [ Time Frame: 5 years ]
    All death is defined as an event of overall survival.

  3. Length of postoperative hospital stay [ Time Frame: 10 days ]
    Length of postoperative hospital stay is defined as a duration between surgery and first discharge. An expected average is 10 days.

  4. Health-related QOL score [ Time Frame: 1 year after surgery ]
    The QOL score was measured using the 36-item Short Form Health Survey (SF-36) version 2.0. It is a tool that measures health-related QOL (HRQOL) according to an inclusive standard and not a disease-specific standard. The SF-36 is composed of 36 questions. The score is expressed numerically by the provided scoring algorithm. SF-36 questionnaires were sent to the patients at one month, 6 months and one year after the surgery by postal mail. A return envelope was enclosed with the SF-36 questionnaire, and the patient sent it back to the research secretariat by postal mail. A questionnaire on the defecation situation and wound pain besides the SF-36 was added all three times. The question of when complete rehabilitation occurred was added in the questionnaire at one year.
