Sphincter-saving proctectomy for rectal cancer in the elderly

Area of Science:

• Oncology
• Surgical Gastroenterology
• Geriatric Medicine

Background:

• Rectal cancer disproportionately affects older individuals.
• Limited research exclusively addresses outcomes in elderly rectal cancer patients undergoing specific surgical procedures.
• Sphincter-saving surgery is a key consideration for maintaining quality of life.

Purpose of the Study:

• To compare short-term and long-term outcomes of sphincter-saving proctectomy for rectal cancer in patients aged 75 and older versus younger patients.
• To evaluate the safety and efficacy of this surgical approach in an elderly population.
• To determine if advanced age is a contraindication for this procedure.

Main Methods:

• Retrospective analysis of 400 consecutive patients with primary rectal adenocarcinoma.
• Patients were divided into two groups: Group 1 (≥75 years, n=98) and Group 2 (<75 years, n=302).
• Outcomes assessed included morbidity, anastomotic leakage, reoperation rates, 30-day mortality, overall survival, and cancer-related survival.

Main Results:

• Patients aged 75 and older experienced significantly higher rates of morbidity and mortality.
• Despite increased short-term risks, cancer-related survival was comparable between the elderly and younger patient groups.
• Overall survival was lower in the elderly cohort, likely influenced by non-cancer-related factors.

Conclusions:

• Advanced age (≥75 years) is not an absolute contraindication for sphincter-saving proctectomy in rectal cancer.
• While elderly patients face increased surgical risks, the oncological benefit in terms of cancer-related survival is preserved.
• Careful patient selection and management are crucial for optimizing outcomes in older adults undergoing rectal cancer surgery.
