GI CANCER OVERVIEW
Understanding Gastrointestinal Cancer
Gastrointestinal cancers develop in different parts of the digestive system. Each type can behave differently and may require a different combination of diagnostic tests and treatments.
Personalised Cancer Treatment
Accurate diagnosis and staging are important for determining the most appropriate treatment approach. Depending on the cancer type and stage, treatment may involve surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy or a combination of treatments.
Gastrointestinal cancer is not a single disease. It includes cancers that arise in different organs of the digestive tract and associated organs. These include the oesophagus, stomach, small intestine, colon, rectum, liver, pancreas and gallbladder.
Symptoms and treatment options can vary considerably depending on where the cancer begins. Some patients may experience changes in bowel habits, abdominal discomfort, difficulty swallowing, unexplained weight loss, persistent indigestion or other symptoms.
A specialist oncology evaluation helps determine whether further imaging, endoscopy, biopsy or other investigations are required and allows treatment to be tailored to the individual patient.

TYPES OF GI CANCER
Types of Gastrointestinal Cancer
Gastrointestinal cancer can develop in different organs of the digestive system. The location and biological characteristics of the tumour influence the symptoms, investigations and treatment approach.
Oesophageal Cancer
Cancer that develops in the oesophagus. Persistent difficulty swallowing, discomfort while swallowing or unexplained weight loss may require evaluation.
Stomach Cancer
Also called gastric cancer, this develops in the stomach and may require surgery, systemic treatment or a combination depending on the stage.
Colorectal Cancer
Cancer affecting the colon or rectum. Diagnosis, staging and treatment depend on the location and characteristics of the tumour.
Liver Cancer
Primary liver cancers originate in the liver and require specialist assessment to determine the most appropriate treatment strategy.
Pancreatic Cancer
Cancer arising in the pancreas may require coordinated assessment involving imaging, pathology and specialist oncology care.
Gallbladder Cancer
A relatively uncommon cancer that may be discovered during investigation of gallbladder disease or other abdominal symptoms.
Small Intestinal Cancer
Tumours of the small intestine are uncommon and can require specialised imaging, endoscopic evaluation or tissue diagnosis.
Gastrointestinal Stromal Tumour
GIST is a distinct type of tumour arising in the gastrointestinal tract and requires pathology-based classification for treatment planning.
Anal Cancer
Cancer involving the anal canal requires assessment of the tumour type and extent before treatment is selected.
DIAGNOSIS
How Is Gastrointestinal Cancer Diagnosed?
Diagnosis begins with a clinical assessment and is followed by investigations selected according to the symptoms and suspected site of disease. A combination of tests may be needed to establish the diagnosis and determine the extent of cancer.
Clinical Evaluation
The doctor reviews symptoms, medical history, family history and risk factors before deciding which investigations are appropriate.
- Detailed medical history
- Physical examination
- Review of symptoms and duration
- Assessment of personal and family history
Endoscopy
Endoscopic procedures allow doctors to directly examine parts of the gastrointestinal tract and obtain tissue samples when required.
- Upper gastrointestinal endoscopy
- Colonoscopy
- Tissue biopsy when indicated
Imaging Tests
Imaging helps assess the location and extent of a suspected tumour and can assist with treatment planning.
- CT scans
- MRI scans when appropriate
- Ultrasound in selected situations
- PET-CT when clinically indicated
Biopsy & Pathology
A biopsy may be required to confirm cancer and determine the tumour type. Pathology findings help guide further treatment decisions.
- Tissue examination
- Tumour classification
- Relevant biomarker testing
Diagnosis is the first step toward an individualised treatment plan.
Once the cancer type and extent are established, specialists can determine whether surgery, systemic treatment, radiation therapy or a combination of approaches may be appropriate.
CANCER STAGING
Understanding Gastrointestinal Cancer Stages
Cancer staging describes how far the disease has developed. The exact staging system varies according to the type of gastrointestinal cancer, but staging generally considers the size and local extent of the tumour, lymph-node involvement and spread to distant organs.
0
Very Early
Abnormal or cancerous cells are limited to the innermost layer in cancers where Stage 0 applies.
I
Localised
Cancer is generally confined to the organ where it began.
II
More Extensive
The tumour has grown further into surrounding tissue, depending on the cancer type.
III
Regional
Regional lymph nodes or nearby structures may be involved.
IV
Advanced
Cancer has spread to distant organs or sites in cancers where Stage IV applies.
Important: Not every gastrointestinal cancer uses exactly the same staging criteria. Your oncology team will explain the specific stage and what it means for your treatment options.
GI CANCER TREATMENT
Gastrointestinal Cancer Treatment Options
Treatment depends on the type and location of the cancer, its stage, tumour characteristics and the patient's overall health. Some patients may require one treatment, while others may benefit from a combination of therapies.
Cancer Surgery
Surgery may be an important part of treatment for gastrointestinal cancers that can be removed safely. The type of operation depends on the location and extent of the tumour.
- Removal of the primary tumour
- Regional lymph-node assessment
- Organ-specific cancer surgery
- Surgery as part of combined treatment
Chemotherapy
Chemotherapy uses medicines to treat cancer cells. Depending on the cancer type and treatment plan, it may be used before surgery, after surgery or as part of treatment for advanced disease.
- Neoadjuvant treatment before surgery
- Adjuvant treatment after surgery
- Treatment of advanced disease
Radiation Therapy
Radiation therapy uses focused radiation to destroy or control cancer cells. Its role varies significantly between different gastrointestinal cancers.
- Local tumour control
- Treatment before or after surgery in selected cancers
- Symptom relief in appropriate situations
Targeted Therapy
Targeted medicines act on specific molecular features of cancer cells. They are considered when testing shows that a particular targeted treatment may be appropriate.
- Biomarker-guided treatment
- Selected advanced cancers
- Treatment based on tumour characteristics
Immunotherapy
Immunotherapy helps the immune system recognise and respond to cancer cells. Its suitability depends on the cancer type and relevant tumour characteristics.
- Selected gastrointestinal cancers
- Biomarker-based treatment decisions
- May be used alone or with other treatments
Multimodal Treatment
Many gastrointestinal cancers are treated using a combination of approaches. Treatment may involve surgery together with chemotherapy, radiation or systemic therapies.
- Treatment tailored to tumour stage
- Coordination between specialists
- Individualised treatment sequencing
SURGICAL ONCOLOGY
Surgery for Gastrointestinal Cancer
When surgery is appropriate, the goal is to remove the cancer while preserving as much healthy tissue and function as reasonably possible. The exact procedure depends on the organ involved and the extent of disease.
Surgical Oncology
Organ-specific cancer surgery
Surgical planning is based on the location of the tumour, its stage, surrounding structures and the patient's overall health.
When can surgery be considered?
Surgery may be considered when the cancer can be removed safely and when surgical treatment is expected to provide meaningful benefit. In some cancers, other treatments may be given before surgery to reduce or control the disease.
The surgical approach is discussed after reviewing imaging, biopsy results and other relevant clinical information.
Tumour Location
Determines the organ-specific surgical approach.
Cancer Stage
Helps determine whether surgery is appropriate
and how it fits into the overall treatment plan.
Surgical Fitness
Overall health and fitness are considered before
major cancer surgery.
Multidisciplinary Planning
Other oncology treatments may be coordinated
with surgery when required.
PERSONALised CARE
How Is the Treatment Plan Decided?
There is no single treatment plan that is appropriate for every gastrointestinal cancer patient. Specialists consider multiple factors before recommending treatment.
From diagnosis to an individualised treatment strategy
STEP 01
Confirm the Diagnosis
Pathology and clinical findings establish the cancer type.
STEP 02
Determine the Stage
Imaging and other investigations assess the extent of disease.
STEP 03
Assess Tumour Biology
Relevant pathology and biomarker information may guide systemic treatment.
STEP 04
Select Treatment
Specialists determine the appropriate treatment sequence for the individual patient.
Every patient is different. Treatment recommendations depend on the specific cancer, stage, pathology, overall health and other clinical factors. A specialist consultation is required to determine the most appropriate treatment approach.
GI CANCER SURGERY
Gastrointestinal Cancer Surgery by Location
The type of surgery depends on where the cancer has developed, its size and stage, involvement of nearby structures and the patient's overall health. Surgical procedures are planned on an individual basis.
Oesophagus
Oesophageal Cancer Surgery
Selected patients may undergo surgery to remove the affected portion of the oesophagus and reconstruct the digestive pathway. The exact procedure depends on the tumour location and extent.
Stomach
Stomach Cancer Surgery
Surgery for gastric cancer may involve removal of part or all of the stomach along with appropriate lymph-node assessment, depending on the tumour's location and stage.
Colon
Colon Cancer Surgery
Colon surgery involves removing the affected segment of the bowel along with surrounding tissue and appropriate lymph nodes when indicated.
Rectum
Rectal Cancer Surgery
Rectal cancer surgery is planned according to the tumour's position, stage and relationship with nearby structures. Other treatments may be given before surgery in selected cases.
Liver
Liver Cancer Surgery
Selected liver tumours may be treated surgically when removal is appropriate. The amount of liver involved and the patient's liver function are important considerations.
Pancreas
Pancreatic Cancer Surgery
Pancreatic surgery is complex and depends on the tumour's location and whether it can be safely removed. Specialist assessment and detailed imaging are essential.
Gallbladder
Gallbladder Cancer Surgery
When surgery is appropriate, the procedure is determined by the extent of the tumour and whether nearby tissues or structures are involved.
GIST
GIST Surgery
Surgery can be considered for localised gastrointestinal stromal tumours when complete removal is feasible. Tumour size, location and biology influence treatment planning.
Small Intestine
Small Intestinal Cancer Surgery
Surgery may involve removal of the affected segment of the small intestine and nearby tissue, depending on the tumour type and extent.
SURGICAL APPROACH
Open, Laparoscopic & Minimally Invasive Approaches
Depending on the cancer type, tumour location, stage and patient's suitability, surgery may be performed using an open or minimally invasive approach. The safest and most appropriate technique is selected for each individual case.
Minimally Invasive Surgery
Laparoscopic or other minimally invasive techniques may be appropriate for selected gastrointestinal procedures. Small incisions and specialised instruments are used instead of a larger conventional incision.
- Smaller surgical incisions in suitable procedures
- Potentially shorter recovery for selected patients
- Reduced wound size compared with some open procedures
- Used only when clinically appropriate
Open Cancer Surgery
Open surgery may be recommended when the tumour is extensive, complex or located in an area where an open approach provides the safest way to achieve the required surgical objective.
- Suitable for selected complex operations
- Allows direct access to the surgical area
- May be necessary for advanced or extensive disease
- Decision based on individual surgical assessment
RECOVERY & AFTERCARE
Recovery After Gastrointestinal Cancer Surgery

Gastrointestinal Cancer Treatment FAQs
Find answers to common questions about gastrointestinal cancers, diagnosis, treatment and specialist care.
Gastrointestinal cancer refers to cancers that develop
in organs and structures of the digestive system. These
can include cancers of the oesophagus, stomach, small
intestine, colon, rectum, liver, pancreas, gallbladder
and other parts of the gastrointestinal tract.
Common gastrointestinal cancers include oesophageal,
stomach, colorectal, liver, pancreatic and gallbladder
cancers. The treatment approach differs depending on
the organ involved and the characteristics of the cancer.
Symptoms can vary depending on where the cancer develops.
Possible symptoms include unexplained weight loss,
persistent abdominal discomfort, changes in bowel habits,
difficulty swallowing, persistent indigestion, blood in
the stool or vomiting. These symptoms can also occur
with conditions that are not cancer, so medical evaluation
is important when symptoms persist.
Diagnosis may involve a combination of clinical
evaluation, imaging investigations, endoscopy and
biopsy. The specific tests depend on the suspected
cancer and the patient's symptoms and clinical findings.
Treatment depends on the cancer type, location, stage,
tumour characteristics, overall health and whether the
cancer has spread. Treatment may involve surgery,
chemotherapy, radiation therapy, targeted therapy,
immunotherapy or a combination of treatments.
Surgery may be an important part of treatment for selected
gastrointestinal cancers, particularly when the tumour
can be safely removed. The type and extent of surgery
depend on the cancer's location, stage and other clinical
factors.
Minimally invasive or laparoscopic surgery may be suitable
for selected gastrointestinal cancer procedures. Whether
it is appropriate depends on the cancer type, tumour
location, stage, complexity of the operation and the
patient's individual circumstances.
No. Chemotherapy is not required for every patient.
Its use depends on the type and stage of cancer and the
patient's treatment plan. It may be recommended before
surgery, after surgery or for advanced disease in
appropriate cases.
Persistent or concerning symptoms should be evaluated by
an appropriate medical professional. If investigations
suggest cancer or a cancer diagnosis has already been
made, an oncology consultation can help determine the
next steps in diagnosis and treatment.
