Study Notes
Understanding Tumours: Clinical Features, Grading and Staging, and Laboratory Diagnosis
Clinical Features of Tumours
- Tumours are often asymptomatic until they reach an advanced stage.
- Clinical features of tumours can be diverse and complex, depending on the site and size of the tumour.
- Tumours can be classified into different groups based on their mass effect, hormone production, para-neoplastic syndrome, and tumour cachexia.
- Grading and Staging of Tumours
- Grading of a cancer is based on the degree of differentiation of the tumour tissue, which is a histological assessment by the histopathologist.
- Tumour staging is about the degree of tumour progression and its local anatomic extension, involvement of regional lymph nodes, and the presence or absence of distant metastasis.
- The most common widely used system for tumour staging is the TNM system, which stands for primary tumour, degree of regional lymph node involvement, and distant metastases.
- Staging of neoplastic disease is very important in the selection of the best form of therapy for the patient.
- Staging has proved to be of greater clinical value than grading.
- Laboratory Diagnosis of Cancer
- The laboratory diagnosis of cancer is usually not difficult, but this depends on a good quality biopsy that is properly preserved.
- Several sampling approaches are available, including excisional or incisional biopsy, needle aspiration cytology, and cytologic smears.
- Other techniques used for laboratory diagnosis include immunohistochemistry, molecular diagnosis, and tumour markers.
