In this study, doctors evaluated the risk factors for mortality, morbidity, and long-term survival in very old patients with colorectal cancer.
Patients operated on for colorectal cancer, who were over 75 years, were divided into 2 groups. Group A included 93 patients aged 75 to 84 years and group B included 21 patients aged ≥ 85 years.
The doctors found that serum albumin level, oxygen pressure in arterial blood gases, and forced expiratory volume in 1 second in group B were lower than in group A.

In addition, pulmonary complications were developed significantly more frequently in group B.
Group B also had a significantly higher mortality rate than group A.
However, the team found no significant differences between the 2 groups for the 2- and 5-year survival rates.
Dr Kunio Takeuchi and colleagues concluded, "Very old patients with colorectal cancer should not be denied surgery on account of chronological age alone, although the perioperative risks for the very old are very high".
