Gastrointestinal Cancer Center
Comprehensive care for gastric and colorectal cancer, from accurate diagnosis and staging to multidisciplinary treatment, surgery, chemotherapy, radiation therapy, and follow-up care.
About the Gastrointestinal Cancer Center
The Gastrointestinal Cancer Center at Inje University Ilsan Paik Hospital specializes in the diagnosis and treatment of gastrointestinal cancers, particularly gastric cancer and colorectal cancer.
Gastric and colorectal cancers can require different treatment strategies depending on the location and stage of the cancer, the patient's overall health, and other medical conditions. Accurate diagnosis and comprehensive treatment planning are therefore essential for appropriate cancer care.
The center brings together specialists from Gastroenterology, Medical Oncology, Surgery, Radiation Oncology, and Radiology. Through collaboration among different specialties, the center aims to provide individualized and coordinated treatment from diagnosis through treatment and follow-up.
Gastric Cancer Care
Accurate diagnosis using upper gastrointestinal endoscopy and biopsy, followed by appropriate treatment planning based on the stage and characteristics of the cancer.
Colorectal Cancer Care
Comprehensive evaluation and treatment of colon and rectal cancer, including surgery, chemotherapy, and radiation therapy when indicated.
Gastroenterology
Specialized evaluation of gastrointestinal diseases, including upper gastrointestinal endoscopy, colonoscopy, biopsy, and endoscopic assessment of suspicious lesions.
Surgical Treatment
Surgical treatment is selected according to the location and stage of the cancer. Minimally invasive approaches such as laparoscopic and robotic surgery may be considered when appropriate.
Medical Oncology
Chemotherapy may be used before or after surgery or as systemic treatment for advanced or metastatic cancer, depending on the patient's disease status and treatment goals.
Radiation Oncology
Radiation therapy may be incorporated into treatment plans, particularly for selected patients with rectal cancer, according to the stage and location of the tumor.
Related Diseases
Gastric Cancer
Gastric cancer most commonly develops from the lining of the stomach.
Treatment planning depends on the depth of tumor invasion,
lymph node involvement, and whether the cancer has spread to other organs.
Colon Cancer
Colon cancer is a malignant tumor that develops in the colon.
The location of the tumor, stage, lymph node involvement,
and distant metastasis are considered when determining treatment.
Rectal Cancer
Rectal cancer develops in the rectum, the final portion of the large intestine.
Depending on the stage and location of the tumor, surgery, chemotherapy,
and radiation therapy may be combined.
Gastrointestinal Tumors
Gastrointestinal tumors can occur in different parts of the digestive tract.
Diagnosis and treatment vary depending on the location, pathology,
and biological characteristics of each tumor.
Accurate Diagnosis and Cancer Staging
Upper gastrointestinal endoscopy and colonoscopy play an important role in detecting suspicious lesions and obtaining tissue samples for biopsy.
When cancer is diagnosed, imaging studies such as abdominal CT and PET-CT may be performed when clinically appropriate to evaluate the location and extent of the cancer, lymph node involvement, and possible distant metastasis.
Accurate staging provides important information for determining whether surgery, chemotherapy, radiation therapy, or a combination of treatments may be appropriate.
Because each patient's cancer and overall health are different, the same type of cancer may require different treatment strategies. Treatment decisions are therefore made based on comprehensive evaluation of diagnostic findings and the patient's individual condition.
Advantages of University Hospital-Based Cancer Care
Treatment of gastric and colorectal cancer may involve multiple specialties. In addition to surgery, some patients may require chemotherapy, radiation therapy, advanced imaging, endoscopic treatment, or management of other medical conditions.
A university hospital provides access to multiple medical specialties and diagnostic and treatment facilities within an integrated medical system. This multidisciplinary environment can support comprehensive evaluation and coordinated cancer treatment.
| Gastroenterology | Performs upper gastrointestinal endoscopy and colonoscopy, evaluates gastrointestinal lesions, and performs biopsy and appropriate endoscopic procedures. |
|---|---|
| Surgery | Provides surgical treatment for gastric and colorectal cancer. Depending on the tumor location, stage, and patient's condition, open, laparoscopic, or robotic surgery may be considered. |
| Medical Oncology | Provides systemic anticancer treatment, including chemotherapy before or after surgery and treatment for advanced or metastatic cancer when clinically indicated. |
| Radiation Oncology | Provides radiation therapy when indicated as part of the treatment plan, including selected cases of rectal cancer. |
| Radiology | Provides diagnostic imaging such as CT and MRI to evaluate the location and extent of cancer, lymph nodes, surrounding structures, and possible metastasis. |
| Pathology | Examines biopsy and surgical specimens to establish the diagnosis and identify pathological characteristics that may contribute to treatment planning. |

Major Diagnostic Tests
Upper Gastrointestinal Endoscopy
Allows direct examination of the esophagus, stomach, and duodenum to identify abnormal lesions and obtain tissue samples when necessary.
Colonoscopy
Allows direct examination of the colon and rectum to identify polyps, tumors, and other abnormal lesions and to obtain biopsies when necessary.
Abdominal CT
Provides detailed images of the abdomen and can help evaluate the primary tumor, surrounding tissues, lymph nodes, and possible distant metastasis.
PET-CT
Combines metabolic and anatomical imaging and may be used in selected patients to evaluate possible metastatic or recurrent cancer.
Pathology Examination
Analyzes tissue obtained through endoscopic biopsy or surgery to confirm the diagnosis and characterize the tumor.
Cancer Staging
Endoscopic findings, pathology, CT, PET-CT, and other appropriate examinations are integrated to determine the extent of disease and guide treatment planning.
Treatment of Gastric Cancer
Treatment for gastric cancer depends on factors such as the depth of tumor invasion, lymph node involvement, distant metastasis, tumor location, and the patient's overall health.
For selected early gastric cancers that meet appropriate clinical and pathological criteria, endoscopic treatment may be considered.
When surgery is required, the type and extent of gastrectomy are determined based on the location and stage of the cancer. Laparoscopic or robotic approaches may be considered when appropriate.
Depending on the cancer stage and risk of recurrence, chemotherapy may be recommended before or after surgery as part of a comprehensive treatment plan.
Treatment of Colorectal Cancer
Treatment of colorectal cancer depends on whether the tumor is located in the colon or rectum, as well as the stage of disease, lymph node involvement, distant metastasis, and the patient's overall condition.
When surgery is required, the affected portion of the colon or rectum is removed according to the location and extent of the tumor. Laparoscopic or robotic surgery may be considered for appropriate patients.
For selected patients with rectal cancer, preoperative chemoradiation or radiation therapy may be incorporated into the treatment plan. The timing and type of treatment depend on the location and stage of the tumor.
Chemotherapy may be administered before or after surgery, or as systemic treatment for advanced disease, depending on the patient's condition and overall treatment strategy.
Laparoscopic and Robotic Surgery
Surgical treatment for gastric and colorectal cancer is selected based on the location and stage of the tumor, anatomical considerations, the patient's overall health, and the goals of treatment.
Laparoscopic Surgery
A minimally invasive surgical approach performed through small incisions using a laparoscope and specialized surgical instruments. It may be considered when clinically appropriate.
Robotic Surgery
Robotic-assisted surgery uses a surgical robotic system to support precise operative procedures. Its use is determined according to the patient's disease characteristics and surgical indications.
Individualized Surgical Planning
The same surgical approach is not appropriate for every patient. Surgical options are selected after considering the tumor location, stage, anatomy, and overall health of each patient.
When Should You Consider Evaluation for Gastric or Colorectal Cancer?
Gastric and colorectal cancer may not cause obvious symptoms during the early stages. Regular cancer screening according to age and individual risk factors is therefore important, even when no symptoms are present.
Persistent indigestion or upper abdominal discomfort, unexplained weight loss, black or bloody stools, changes in bowel habits, persistent abdominal pain, or unexplained anemia may require medical evaluation.
If symptoms such as gastrointestinal bleeding, persistent abdominal pain, or unexplained weight loss continue or worsen, appropriate medical evaluation can help determine the underlying cause.
