Question 5

investigation of choice in pacreatic cancer

Answer 5

• ultrasound has a sensitivity of around 60-90%
• high-resolution CT scanning is the investigation of choice if the diagnosis is suspected

• less than 20% are suitable for surgery at diagnosis
• a Whipple’s resection (pancreaticoduodenectomy) is performed for resectable lesions in the head of pancreas. Side-effects of a Whipple’s include dumping syndrome and peptic ulcer disease
• adjuvant chemotherapy is usually given following surgery
• ERCP with stenting is often used for palliation

Question 9

A 38-year-old woman with a diagnosis of oestrogen receptor-positive (ER+ve), HER2-negative breast cancer in her right breast has undergone wide local excision (WLE) and sentinel node biopsy. Histopathological examination reveals one positive sentinel node.

Her menstrual cycles last 28 days, and she experiences regular periods lasting four days at a time.

What further treatment should be offered to this patient?

Answer 9

**Radiotherpay and tamoxifen **

• In patients with breast cancer undergoing breast conserving surgery with adjuvant radiotherapy if, at sentinel node biopsy, less than 3 involved nodes are found then no further management of the axilla is required
• All patients who undergo WLE should receive adjuvant radiotherapy to reduce the risk of recurrence.
• Similarly, given that the patient has not been through menopause, as shown by her regular periods, and her tumour is ER+ve, they should also be commenced on hormonal therapy. Tamoxifen is a selective oestrogen receptor modula
