Introduction

Colorectal cancer is one of the most commonly diagnosed cancers worldwide, affecting both the colon and rectum. Early detection through routine screening, accurate diagnosis and multidisciplinary treatment planning play a vital role in improving patient outcomes. Advances in diagnostic imaging, minimally invasive surgery and personalised cancer therapies have significantly expanded treatment options for many patients.

At Xi’an Chang’an Hospital, colorectal cancer care is provided by a multidisciplinary team that includes colorectal surgeons, gastroenterologists, medical oncologists, radiation oncologists, radiologists and specialist nursing staff. Every treatment plan is developed according to the patient’s diagnosis, cancer stage and overall health.

International patients also receive coordinated support throughout their treatment journey.

Understanding Colorectal Cancer

Colorectal cancer develops when abnormal cells form within the lining of the colon or rectum. Many colorectal cancers begin as benign polyps that gradually become cancerous over time. Regular screening allows these polyps to be identified and removed before cancer develops.

Treatment depends on the tumour location, cancer stage and individual patient factors.

Common Symptoms

Symptoms may include:

  • Persistent changes in bowel habits
  • Blood in the stool
  • Rectal bleeding
  • Abdominal pain or cramping
  • Unexplained weight loss
  • Fatigue
  • Iron deficiency anaemia
  • Feeling that the bowel does not empty completely

Early-stage colorectal cancer may produce few or no symptoms, making screening particularly important.

Diagnosis

Accurate diagnosis is essential before treatment begins.

Investigations may include:

  • Medical history and physical examination
  • Colonoscopy
  • Biopsy
  • CT Scan
  • MRI where appropriate
  • PET-CT imaging
  • Blood tests
  • Pathology examination
  • Cancer staging

Advanced diagnostic imaging allows specialists to determine the extent of disease and develop an individualised treatment strategy.

Treatment & Procedures

Multidisciplinary Team (MDT)

Each patient’s diagnosis is reviewed by a multidisciplinary colorectal oncology team to develop a personalised treatment plan using current clinical evidence and modern treatment techniques.

Colorectal Surgery

Depending on tumour location and stage, surgery may include minimally invasive or open procedures designed to remove the cancer while preserving bowel function whenever possible.

Medical Oncology

Medical treatment may include:

  • Chemotherapy
  • Targeted therapy
  • Immunotherapy
  • Personalised systemic treatments

Treatment recommendations depend upon tumour biology, staging and the patient’s overall health.

Radiation Oncology

Radiation therapy may be recommended for selected patients, particularly in the treatment of rectal cancer, either before surgery or as part of combined treatment strategies.

Interventional Procedures

For selected patients, minimally invasive interventional procedures may form part of an overall treatment strategy based on individual clinical circumstances.
