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 is crucial at the time of initial presentation to provide appropriate management for a patient.
- Overstaging can deprive a patient from receiving curative treatment, such as surgery, while understaging can lead to futile treatments that increase morbidity and mortality.
- Imaging plays a significant role in staging, with bone imaging using 99mTc MDP and 18F having established value in detecting metastatic bone disease.
- Radiopharmaceuticals are used in staging and follow-up of neuroendocrine tumors.
Importance of Accurate Staging
- Ideal staging is a microscopic process, but it is not always possible to biopsy each lesion to determine if it is malignant.
- Nuclear medicine procedures, such as 18F FDG-PET, have higher accuracy compared to CT or MRI alone in staging tumors, particularly for lymph node involvement.
- The accuracy of CT in staging mediastinal disease in lung cancer is approximately 70%, while MRI is slightly higher at around 80%, and 18F FDG accuracy is better than 90%.
