Long-term follow-up of patients treated with radical surgery for rectal cancer

In developed societies colorectal cancer (CRC) is the second most frequent malignant tumor which causes more than 5000 deaths yearly in Hungary. We have attempted to answer the question how to improve the above mentioned data by the long-term follow-up of patients operated upon for rectal cancer at our department. Of the patients operated on for rectal cancer at our department between March 1990 and April 2006, we have conducted regular follow-up of 297 patients according to a protocol developed by us. We have examined the length of time between the rectum operation and the diagnosis and the number of local recurrences, distant metastases, tumor progression in more than one organ as well as second tumors (independent of the rectal cancer). During this period we found 24 local recurrences, 32 distant metastases, 43 tumor progressions in more than one organ, and 21 second tumors. In two patients, in addition to distant metastases, we found a second CRC independent of the original rectal cancer, and in one patient with tumor progression in more than one organ we also detected breast cancer. In one patient we found 3 second tumors (CR, lung and urinary bladder) independent of the original rectal cancer. Altogether we found tumors in 117 out of 297 patients. During the same period, we performed 69/117 operations and 31/117 patients were alive at the end of our study with a median survival of 60.4 (3-184) months. In summary, we can state that this work is beneficial for curing the recurrence of rectal cancer, making the patients' life longer or making the quality of life better for the patients operated on for rectal cancer.
