Robotic Cancer Surgery
Message from Dr. Ajay Simha
A cancer diagnosis can be overwhelming for patients and their families. When surgery is recommended, patients naturally have concerns about the type of procedure, safety, recovery, pain and the impact of surgery on their daily life.
Advances in surgical technology have introduced robotic-assisted surgery as an option for selected cancer procedures. Robotic systems allow the surgeon to operate through small incisions using specialized instruments and a high-definition, magnified view of the surgical field.
I am Dr. Ajay Simha, Consultant Surgical Oncologist (Cancer Surgeon), and this page provides an overview of robotic cancer surgery, including when it may be recommended, how patients are evaluated, available surgical approaches, recovery and commonly asked questions.
What Is Robotic Cancer Surgery?
Robotic cancer surgery is a form of minimally invasive surgery in which the surgeon uses a robotic surgical system to perform an operation through small incisions. During the procedure, a high-definition camera provides a magnified view of the surgical area. Specialized instruments attached to robotic arms are introduced through small incisions and controlled by the surgeon from a console.
When is Robotic Cancer Surgery Recommended?
Robotic cancer surgery may be considered when a cancer can be safely and effectively treated using a minimally invasive approach.
The suitability of robotic surgery depends on several factors, including:
- Type and location of the cancer
- Size and extent of the tumour
- Stage of the cancer
- Involvement of nearby organs or lymph nodes
- Previous surgeries or treatments
- Patient’s overall health and fitness for surgery
- Complexity and technical requirements of the planned operation
- Ability to achieve complete cancer removal safely
Not every cancer patient is suitable for robotic surgery. In some situations, laparoscopic or open surgery may be more appropriate. The surgical approach is selected after detailed evaluation, with the primary goal of achieving safe and effective cancer treatment.
Evaluation of Robotic Cancer Surgery
Before recommending robotic cancer surgery, a detailed assessment is performed to understand the cancer and determine whether a minimally invasive approach is appropriate.
Imaging investigations such as CT scans, MRI, PET-CT or other appropriate scans may be performed to determine the location and extent of the tumour.
A biopsy may be required to confirm the diagnosis and determine the type of cancer. Depending on the cancer, additional investigations may be performed to assess lymph node involvement or spread to other organs.
Treatment Options for Robotic Cancer Surgery
Cancer treatment depends on the type, stage and location of the cancer, as well as the patient’s overall health. Surgery may be combined with other treatments when required as part of a multidisciplinary cancer treatment plan.
Surgery may be recommended to remove a localized cancer, along with an appropriate margin of surrounding tissue and nearby lymph nodes when required. For selected patients, the required cancer operation can be performed using a robotic-assisted approach. The objective remains complete and safe cancer removal while minimizing unnecessary tissue trauma.
Chemotherapy uses anti-cancer medicines to destroy or control cancer cells. It may be administered before surgery to shrink a tumour, after surgery to reduce the risk of recurrence, or as part of treatment for advanced cancer. The timing and type of chemotherapy depend on the cancer type, stage and individual treatment plan.
Radiation therapy uses high-energy radiation to destroy cancer cells. It may be given before or after surgery for selected cancers and may sometimes be combined with chemotherapy. The decision to use radiation therapy depends on the type and stage of cancer and the expected benefit from treatment.
Immunotherapy helps the body's immune system recognize and attack cancer cells. It may be recommended for selected cancers based on the type and stage of disease and specific characteristics of the tumour.
Targeted therapy uses medicines designed to act on specific molecules or biological pathways involved in cancer growth. These medicines may be recommended when the cancer has particular molecular or genetic characteristics that make it suitable for targeted treatment.
Supportive Care
Supportive care is an important part of cancer treatment and helps patients maintain their nutrition, strength, mobility and overall well-being during treatment and recovery.
Nutritional Support
Good nutrition is important before and after cancer surgery. Some patients may have difficulty maintaining adequate nutrition because of the cancer, previous treatment or the effects of surgery. A personalized nutritional plan may help maintain strength and support recovery. Nutritional requirements vary depending on the type of cancer, planned surgery and the patient’s overall condition.
Physiotherapy
Physiotherapy and early mobilization may help patients regain strength and mobility following cancer surgery. Depending on the procedure, physiotherapy may include breathing exercises, mobility training, muscle strengthening and guidance on returning to normal daily activities.
Surgical Approaches for Robotic Cancer Surgery
The choice of surgical approach depends on the cancer, its location and extent, the patient’s overall health and the complexity of the planned procedure.
In robotic-assisted surgery, the surgeon operates through small incisions using specialized instruments connected to a robotic surgical system.
The surgeon controls the instruments from a console while viewing the surgical field through a high-definition, magnified camera. The system translates the surgeon's movements into precise instrument movements inside the body.
Recovery varies depending on the type and extent of the cancer operation, the patient's general health and whether additional cancer treatments are required.
Because robotic surgery uses smaller incisions, selected patients may experience less postoperative discomfort, smaller scars and an earlier return to normal activities compared with some open procedures.
Dr. Ajay Simha has experience in advanced cancer surgery using robotic, minimally invasive and open surgical techniques. The choice of approach is individualized, with emphasis on complete cancer removal, patient safety, surgical precision and optimal recovery.
Frequently Asked Questions
Robotic cancer surgery is a minimally invasive surgical technique in which the surgeon controls specialized instruments through a robotic surgical system to perform cancer surgery through small incisions.
No. Robotic cancer surgery is performed by the surgeon. The robotic system provides enhanced visualization and allows the surgeon to control specialized instruments with precise movements. The robot does not independently perform the operation.
For appropriately selected patients, robotic surgery may provide smaller incisions, less postoperative pain, reduced scarring and potentially faster recovery. The technology may also provide enhanced visualization and precise instrument control during complex procedures.
No. The suitability of robotic surgery depends on the type, location and stage of cancer, the extent of the tumour, the patient's overall health and the complexity of the operation.
Robotic surgery is not necessarily better than open surgery for every patient. Both approaches have an important role in cancer treatment. The safest and most effective approach is selected based on the individual cancer and the patient's condition.
