Purpose:
The feasibility of neoadjuvant therapy (NAT) for elderly patients with rectal cancer has not been evaluated well.
Methods:
Between 2004 and 2014, 506 patients with locally advanced low rectal cancer underwent curative resection. Fifty-four were over 75 years old (elderly group), and 452 were under 75 years old (young group). The patients were divided into sub-groups according to whether they received NAT.
Results:
Nineteen (35.2%) patients from the elderly group and 348 (77.0%) from the young group received NAT. The proportion of patients who received NAT was significantly lower in the elderly group. In the elderly group, the median age and prevalence of co-morbidities were significantly lower in patients with than in those without NAT. The incidence of severe adverse events was similar in the two groups. On multivariate analysis, age was not related to postoperative complications in patients who received NAT. The 5-year local recurrence rate was significantly lower in the elderly patients who received NAT, and similar to that of the young patients who received NAT.
Conclusions:
Neoadjuvant therapy was feasible and should be considered as a treatment option for carefully selected elderly patients with locally advanced low rectal cancer.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
