- Staging of oesophageal malignancy is aimed at assessing the extent of local invasion of the primary tumour and for the presence or absence of nodal / distal metastatic disease
- CT chest, abdomen and pelvis is suitable initial staging modality
- If this initial investigation demonstrates a lesion that is amenable to potential curative resection, further staging should include a PET-CT scan
- If a PET-CT scan shows no distal metastatic disease, endoscopic ultrasound (EUS) is indicated for local staging

Computed Tomography (CT) Chest, Abdomen and Pelvis
CT Chest, Abdomen and Pelvis
Initial staging test of choice for oesophageal carcinoma
- Initial staging test of choice for oesophageal cancer ,
- A positive CT finding enables stratifying patients with unresectable disease due to locally advanced tumour and / or with distant metastasis. If CT shows advanced local disease or distant metastases, no further staging is required, as palliative treatment is the only option
- CT is specific in assessing local unresectability with a specificity for T4 tumours >90% but a low sensitivity of 25%. Furthermore, CT is moderately sensitive and is specific for metastatic disease (M1)
- The importance of N-staging in recent years has also seen a drop following the introduction of neoadjuvant therapy
- Limitations
- Less sensitive in differentiating the layer of the oesophageal wall (T-staging) resulting in
- Under staging of T3 and T4 tumours
- Unreliable to distinguish T1 from T2 and T2 from early T3 tumours
- Inaccurate assessment of regional lymph node disease (N-stage)
- Less sensitive in differentiating the layer of the oesophageal wall (T-staging) resulting in
Positron Emission Tomography-Computed Tomography (PET-CT)
PET-CT
Further stratifying patients unsuitable for surgery due to unresectable and / or metastatic disease. More sensitive than CT for detecting distant metastatic disease
- PET-CT is more sensitive than CT for metastatic disease (M1) and is moderately specific ,
- It is more accurate compared to the combination of CT and EUS
- PET-CT can detect occult metastases in up to 13% and change management in 38% of patients and have been shown to be of prognostic value independent of TNM stage ,
- Improves diagnostic specificity for lymph node staging ,
- Co-registration of PET and CT images using PET-CT systems may be more accurate than PET alone. , PET-CT offers additional information over conventional CT and EUS for the staging of oesophageal cancer
- Limitations ,,,
- Inability to determine T-stage of the oesophageal tumour
- Inaccurate in the detection of local lymph node metastases
- Lack of anatomical detail
- Expensive and limited availability
Endoscopic Ultrasound ± Fine Needle Aspiration (FNA)
Endoscopic Ultrasound + FNA (Fine Needle Aspiration)
Most accurate modality for loco-regional tumour and lymph node staging of oesophageal carcinoma
- EUS has shown to be the most accurate modality for loco-regional tumour and lymph node staging. Accuracy of EUS alone without fine needle aspiration (FNA) is approximately 70%
- High frequency catheter probe (HFCP) is useful for distinguishing between mucosal cancer and cancer invading the submucosa, with an accuracy of 81-100%. However despite using a higher frequency, it has been difficult to distinguish between tumour invasion and inflammatory cell infiltration
- Hence employing FNA in the same setting, in selected cases increases the accuracy of N-staging to >90 per cent ,,,
- Indicated in patients with oesophageal cancer in whom a CT scan has ruled out T4 and M1 disease /li>
- 30% of PET node negative (N0) patients were EUS node positive (N+) emphasizing the prognostic value of EUS has for nodal staging in this group of patients
- The low number of false-negative results for EUS meant that a negative EUS result will be in most patients a truly negative one. Other advantages include assisting in patient selection for endoscopic therapy ,,
- Limitations
-
- Incomplete examinations due to impassable stenosing tumours (which may be overcome by the use of miniprobes) ,
- Difficulties with specificity for nodal involvement (reactive versus malignant). However, it can be overcome by the ability to combine fine needle aspiration with EUS, allowing histological verification of identified lymph nodes (e.g. coeliac lymph nodes) ,
- Note: suspicion of tracheo-bronchial involvement may require bronchoscopy or bronchoscopic ultrasonography
Treatment
Treatment
T1N0
- Surgery with curative intent is still considered the criterion standard treatment for resectable oesophageal cancer
- However mortality and morbidity rates associated with oesophageal surgery is notable thus minimally invasive endoscopic therapy is favoured if available, particularly in suspected T1N0 staged tumours diagnosed with EUS
- Depth of tumour invasion, tumour free margins, lymphatic and venous invasion, and grade of differentiation can be assessed with EUS
- Endoscopic mucosal resection (EMR) specimens of T1 oesophageal carcinoma identified positive lymph node rates of <5% in T1a and between 12-46% in T1b. Accuracy of EUS in staging of superficial oesophageal carcinoma, differentiating T1a from T1b is as high as 85%
T1N1 or T2-3 N0-1
- T1N1 or T2-3 N0-1 staged tumours with no evidence of metastatic disease benefited from preoperative chemoradiotherapy (five courses of carboplatin and paclitaxel and 41.4 Gy via external beam radiation) followed by surgery
- Not only was it safe but the therapy improved survival among patients with potentially curable adenocarcinoma or squamous cell carcinoma (SCC) of the oesophagus or esophagogastric-junction. However SCC would require a more radical chemoradiotherapy especially for proximal lesions
Staging of Oesophageal Cancer
Staging of Oesophageal Cancer
It is vital to determine the depth of mural (T stage), nodal (N stage) infiltration and distant metastasis (M stage) of the primary tumour to determine treatment strategies, either curative or palliative
- Accurate staging of cancer is important for prognostication and directing further therapy. The most common staging system used for oesophageal malignancy is the American Joint Committee on Cancer tumour-node-metastases (AJCC TNM) score ,
