Aims:
To describe the neopastic findings and stages of colorectal cancer (CRC) in in CCR screening asymptomatic participants.
Methods:
Screening programme for CRC was introduced in our hospital in october 2014. We collected data until August 2017. Men and women between 50 and 69 years old were invited to undergo a Faecal Occult Blood Test (FOBT). Those who obtained a positive result were offered a colonoscopy.
Results:
1815 colonoscopies were performed during this time, 1124 were males and 691 females (38%). Of those 1815, colonoscopies were negative or had non neoplastic findings in 611 (33.7%) participants, while adenomas were resected in 1053 (58%).
151 participants (112 males and 39 females) were diagnosed of invasive CRC. 86 (57%) were diagnosed in stage I (64 males and 22 females), 16 of these 86 were completely resected by polipectomy; 24 (15.9%) in stage II (21 males and 3 females); 36 (23.8%) in stage III (25 males and 11 females) and 5 (3.3%) in stage IV (2 males and 3 females).
The probability of being diagnosed of CRC was higer in males (RR 1.77, 95% IC 1.24 – 2.51; p = 0.0015). Advanced stages of CRC were more frequent in female than in male (35.9% vs. 24.1%) p = 0.15.
Conclusions:
Almost in 60% of asymptomatic participants, adenomas were resected, avoiding their progression to advanced neoplasias.
73% of tumors were diagnosed in early stages (stages I and II), when surgery is curative.
In less than 1/3 of the cases cancer had spread to regional lymph nodes and in only 8 had metastasized to other organs.
Taking the sex into account, invasive CRC was more frequent in males, but when a female is diagnosed of CRC in our screening programme, advanced stages of CRC (III and IV) were more frequent, although it was not significant.
In 16 patients with invasive CRC colonoscopy was therapeutic.
