Understand the pre operative evaluation for Robotic Oncologic Surgery. Learn about tests like Computed Tomography 256 Slice, PET CT, PCR, and 3 Tesla MR.
Evaluation Before Treatment
Initial Consultation And History
The evaluation process begins with a detailed consultation with the oncologic surgeon. The doctor will review the complete medical history of the patient including the cancer diagnosis previous biopsies and family history. They will assess risk factors and current symptoms. This initial step establishes the need for surgery and identifies any potential risks. The doctor will explain why robotic surgery is the recommended course of action based on this history and perform a physical examination to check general health status.
Diagnostic Imaging With Computed Tomography 256 Slice

The Computed Tomography 256 Slice scanner is an ultra fast CT machine that captures detailed cross sectional images of the body. In oncology it is used to visualize primary tumors and check for spread to other organs.
The speed of the scan reduces motion artifacts providing crystal clear images of the anatomy. This roadmap is vital for the surgeon to plan the robotic surgery allowing them to identify the exact location of the tumor relative to blood vessels and other organs ensuring a safe and complete resection.
Advanced Imaging With 3 Tesla MR

3 Tesla MR or 3T MRI represents the gold standard in magnetic resonance imaging for soft tissues. In cancer care it is particularly useful for evaluating tumors in the brain prostate rectum and liver. It uses a powerful magnetic field to create highly detailed images without radiation.
The high resolution allows the surgeon to see the tumor boundaries clearly and determine if the cancer has invaded nearby tissues. This precise mapping aids in surgical planning and helps determine if a nerve sparing approach is feasible.
Metabolic Imaging With PET CT
PET CT combines positron emission tomography with computed tomography to provide metabolic and anatomic information. In oncology it is used to stage cancer by assessing metabolic activity. It uses a radioactive sugar tracer to light up areas of high metabolic activity which are often cancer cells. This scan is highly sensitive for detecting lymph node metastases and distant spread. A positive PET CT might change the treatment plan from surgery to systemic therapy. It is a critical tool for accurate staging.
Functional Evaluation With Spect CT
Spect CT or Single Photon Emission Computed Tomography combined with CT provides functional information about organs. It is used for sentinel lymph node mapping in cancers like breast and melanoma and sometimes in complex urologic cancers. By showing lymphatic drainage patterns it helps the surgeon identify which lymph nodes are most likely to contain cancer cells. This guides the extent of lymph node dissection during the robotic surgery balancing the need for staging with the risk of lymphedema.
The Role Of Scintigraphy In Evaluation
Scintigraphy is a nuclear medicine test used to evaluate organ function and detect bone metastases. A bone scan is a type of scintigraphy commonly used in prostate and breast cancer staging. A radioactive tracer is injected and accumulates in areas of high bone turnover which can indicate metastasis. This test ensures that the cancer has not spread to the bones before proceeding with curative surgery. It helps in selecting patients who will benefit most from local control of the disease.
Genetic Testing And PCR Analysis
PCR or Polymerase Chain Reaction is a laboratory technique used to amplify DNA sequences. In oncology it is used for genetic testing of tumors and to detect specific mutations that might drive cancer growth. Understanding the genetic profile of a tumor can influence treatment decisions. For example certain genetic markers might indicate a more aggressive cancer requiring wider resection or specific adjuvant therapies. PCR testing of tissue or blood samples provides molecular level insights that guide personalized treatment strategies.

Frequently Asked Questions
Why is a Computed Tomography 256 Slice better than a standard CT?
The 256 Slice CT is faster and captures more detail in a single rotation providing clearer images for precise surgical planning.
Is a PET CT safe?
Yes it involves a small amount of radiation from the tracer and the CT scan but the diagnostic value for accurate cancer staging outweighs the risk.
What does PCR tell the doctor?
It analyzes the DNA of the tumor or patient to identify specific mutations that can guide surgical extent and future treatments.
Why do I need a 3 Tesla MR?
It provides detailed images of soft tissues like the prostate or rectum helping to see tumor boundaries more clearly than standard MRI.
How long does the evaluation take?
The evaluation process including all scans and clearances typically takes one to two weeks to ensure comprehensive planning for surgery.
