Q

What investigations are needed in Oesophageal Cancer?

Study These Flashcards
A
  1. Upper G.I. Endoscopy with Biopsy
  2. CT/PET Scan
  3. Endoscopic Ultrasound
23
Q

What is the purpose of the Upper G.I. Endoscopy with Biopsy?

Study These Flashcards
A
  1. To view and assess the severity of the tumour

2. The Grade the cancer

24
Q

What is the purpose of the CT/PET scan?

Study These Flashcards
A

This is used for Staging Purposes - looking for Metastases

25
Where needs to be scanned in the CT/PET scan?
1. Chest 2. Abdomen 3. Pelvis
26
What is the purpose of the Endoscopic Ultrasound?
To assess the surrounding structures - for Staging Purposes
27
What staging Criteria is used?
TNM

What are the Different "T" stages in Oesophageal Cancer?
1. T1a 2. T1b 3. T2 4. T3 5. T4
29
What does "T1a" refer to?
A Tumour which has invaded the Lamina Propria
30
What does "T1b" refer to?
A Tumour which has invaded the Sub-Mucosa
31
What does "T2" refer to?
A Tumour which has invaded the Muscularis Externa
32
What does "T3" refer to?
A Tumour which has invaded the Oesophageal Adventitia
33
What does "T4" refer to?
A Tumour which has invaded the Adjacent (Surrounding) Structures
34
What are the Different "N" stages in Oesophageal Cancer?
1. N0 | 2. N1
35
What does "N0" refer to?

1. M0 | 2. M1
38
What does "M0" refer to?
No Metastases
39
What does "M1" refer to?
Metastases
40
What is the only Cure of Oesophageal Carcinoma?
An Oesophagectomy
41
What is an Oesophagectomy?
The Surgical Removal of the Oesophagus, and the Stomach is stretched to reach the Upper Oesophageal Sphincter
42
What is used alongside the Oesophagectomy?
Chemotherapy
43
What are the 2 times Chemotherapy can be used?
1. Adjuvant | 2. Neoadjuvant
44
What is Adjuvant Chemotherapy?
Chemotherapy after the Operation, to remove anything which might be left
45
What is Neoadjuvant Chemotherapy?
Chemotherapy before the Operation, to reduce the size of the tumour
46
What are some palliative care options?
1. Endoscopic Stenting 2. Endoscopic Argon Plasma Coagulation 3. Percutaneous Endoscopic Gastrostomy (PEG) 4. Chemotherapy 5. Radiotherapy
47
What is the function of the Endoscopic Stenting?
To reduce the Symptom of Dysphagia
48
What is the function of Endoscopic Argon Plasma Coagulation?
To reduce the Symptom of Bleeding (Haematemesis)
49
What is the function of a Percutaneous Endoscopic Gastrostomy?
To allow feeding to take place if the Tumour is too large that it obstruct the whole passage to the Stomach
50
What is the function of Palliative Chemotherapy / Radiotherapy?
This is just done to reduce the Symptoms
