Shanghai is home to some of China's most advanced colorectal oncology centers. At China Medical Concierge Shanghai (CMCS), we connect international patients with leading colon cancer specialists, guiding you through every step of diagnosis, treatment, and recovery.
What is Colon Cancer?
Colon cancer (colorectal cancer) is a malignancy arising from the inner lining of the large intestine (colon). It is one of the most common cancers worldwide, ranking third in incidence globally. In China, rates have risen significantly in urban populations over the past two decades, driven by dietary and lifestyle changes. Most cases develop from benign polyps that, if detected early, can be removed before becoming cancerous.
Symptoms
Early-stage colon cancer often presents no symptoms. As the disease progresses, patients may experience:
- Changes in bowel habits (persistent diarrhea or constipation)
- Blood in the stool or rectal bleeding
- Abdominal pain, cramping, or bloating
- Unexplained weight loss and fatigue
- A feeling that the bowel does not empty completely
- Narrow or ribbon-like stools
Diagnosis
Accurate staging is essential for determining the optimal treatment plan. Diagnostic tools used at Shanghai's top hospitals include:
- Colonoscopy with biopsy — the gold standard for detection and tissue sampling
- CT colonography — minimally invasive imaging alternative
- MRI and CT scans — for local staging and detecting distant metastases
- PET-CT — to assess systemic spread
- Molecular and genetic testing — including KRAS, NRAS, BRAF, and MSI/MMR status to guide targeted therapy
- CEA blood marker — for monitoring treatment response
Treatment Options
Shanghai's leading hospitals offer a full spectrum of evidence-based treatments, delivered by multidisciplinary teams:
Surgery
Surgical resection remains the primary curative treatment for localized colon cancer. Minimally invasive laparoscopic and robotic-assisted colectomy techniques are widely available, offering faster recovery and reduced complications compared to open surgery.
Chemotherapy
Adjuvant chemotherapy (e.g., FOLFOX, CAPOX regimens) is recommended for Stage III and high-risk Stage II patients to reduce recurrence risk. For metastatic disease, systemic chemotherapy is the backbone of treatment.
Targeted Therapy
Patients with specific genetic profiles may benefit from targeted agents such as bevacizumab (anti-VEGF) or cetuximab/panitumumab (anti-EGFR, for RAS wild-type tumors), significantly improving outcomes in advanced disease.
Immunotherapy
For tumors with high microsatellite instability (MSI-H) or mismatch repair deficiency (dMMR), immune checkpoint inhibitors such as pembrolizumab have demonstrated remarkable efficacy and are now a standard option.
Radiation Therapy
While less commonly used for colon cancer than rectal cancer, radiation may be employed in select cases of locally advanced or recurrent disease.
