Gastrointestinal Cancers

01 — Gastrointestinal Cancers

Overview

Gastrointestinal cancers develop in organs of the digestive system and can affect different parts of the gastrointestinal tract. These cancers vary considerably in their behaviour, biological characteristics and treatment requirements.

Medical oncology can play a role before or after surgery, as well as in advanced or recurrent disease. Accurate diagnosis and staging are important for determining which combination of treatments is most appropriate.

Common Signs & Symptoms

  • 01Persistent abdominal discomfort or pain
  • 02Unexplained weight loss or loss of appetite
  • 03Persistent indigestion, nausea or changes in digestion
  • 04Changes in bowel habits
  • 05Difficulty swallowing

These signs do not always mean cancer, but any new or persistent symptom should be assessed by a doctor.

Diagnosis & Staging

Depending on the suspected cancer, evaluation may include imaging, endoscopy, blood tests and tissue biopsy. Pathology helps confirm the cancer and determine its specific characteristics. Additional molecular or biomarker testing may be appropriate for some tumours and can provide information relevant to systemic treatment. Staging is used to assess the extent of disease and support treatment planning.

Treatment Options

Treatment varies by the organ involved and stage of disease. It may include surgery, chemotherapy, radiation therapy, targeted therapy or immunotherapy, with different approaches combined when appropriate. Some treatments may be used before surgery, while others may be given after surgery or for advanced disease.

Surgery

May be combined with other approaches when appropriate.

Radiation therapy

May be combined with other approaches when appropriate.

Systemic treatments

  • Chemotherapy
  • Targeted therapy
  • Immunotherapy

When treatments may be given

  • Before surgery
  • After surgery
  • For advanced disease

The treatment plan is tailored to the cancer’s specific characteristics and the patient’s overall condition.

Dr. Taori’s Approach

Dr. Taori has a broad background in solid tumour oncology and academic experience involving gastrointestinal malignancies, including presentations on primary gastrointestinal lymphoma. His care focuses on medical oncology assessment and coordination with the wider multidisciplinary team. The role of systemic treatment is considered in relation to the tumour type, stage and available pathology. This allows the medical oncology plan to be integrated with surgical, radiation and other specialist care when required.
