Study Notes
Staging of Malignant Disease
- Staging of cancer depends on the size of the primary neoplasm, its extent to regional lymph nodes, and the presence or absence of metastasis.
- Accurate staging at initial presentation is crucial to provide appropriate management for a patient.
Importance of Accurate Staging
- Overstaging can deprive a patient from receiving curative treatment such as surgery.
- Understaging can lead to futile treatments, increasing morbidity and mortality without improving the chance of cure.
Role of Imaging in Staging
- Imaging plays a significant role in staging, particularly in detecting metastatic bone disease using 99mTc MDP and 18F.
- Radiopharmaceuticals are used in staging and follow-up of neuroendocrine tumors.
Accuracy of Imaging Modalities
- 18F FDG-PET has a higher degree of accuracy (better than 90%) compared to CT (approximately 70%) and MRI (around 80%) in staging tumors, particularly lymph node involvement.
