Older recommendations taken directly from SIGN 29 are clearly marked with a SIGN
29 symbol and a green font. It should be remembered that these older recommendations
have not been developed with the rigour of current SIGN methodology and the evidence
on which they are based may have been superseded.

B All patients should have a full clinical examination.
B Where a localised abnormality is present, patients should have imaging usually followed
byneneedleaspiratecytology or core biopsy.
B A lesion considered malignant following clinical examination, imaging or cytology alone
should,wherepossible,havehistopathologicalconrmationofmalignancybeforeany
denitivesurgicalproceduretakesplace (eg mastectomy or axillary clearance).
D Patients should be seen at a one-stop, multidisciplinary clinic involving breast clinicians,
radiologists and cytology.
24
C Clear lines of communication should be maintained between the primary care team and
staff in the breast unit.
C The GP should be made aware of the information given to the patient and relatives.
26
A Psychological support should be available to women diagnosed with breast cancer at the
clinic.

C Centres and units should develop an integrated network of cancer care using common
clinical guidelines, management protocols and strategies of care.

B In patients with symptomatic disease two-view mammography should be performed as
part of triple assessment (clinical assessment, imaging and tissue sampling) in a designated
breast clinic.
B Mammography is not recommended in women under the age of 35 years unless there is
a strong suspicion of carcinoma.

A All women with early stage invasive breast cancer who are candidates for breast
conserving surgery should be offered the choice of breast conserving surgery (excision
of tumour with clear margins)ormodiedradicalmastectomy.
A The choice of surgery must be tailored to the individual patient, who should be fully
informed of the options and who should be aware that breast irradiation is required
following conservation and that further surgery may be required if the margins are
positive.
C Breast conserving surgery is contraindicated if:
the ratio of the size of the tumour to the size of the breast would not result in
acceptable cosmesis
there is multifocal disease or extensive malignant microcalcification on
mammogram
there is a contraindication to local radiotherapy (eg previous radiotherapy at this site,
connective tissue disease, severe heart and lung disease, pregnancy).
C Central situation of the tumour is not a contraindication to conservation, although it may
require excision of the nipple and areola, which may compromise cosmesis.
3.2 BREAST RECONSTRUCTION AFTER MASTECTOMY
C The possibility of breast reconstruction should be discussed with all patients prior to
mastectomy.

111
A Neoadjuvant chemotherapy should be considered for women with large cancers as it
improves the rate of breast conservation and is not detrimental to long term
outcome.

5.6 ROLE OF BISPHOSPHONATES

148
A Bisphosphonates should be routinely used in combination with other systemic therapy in
patients with metastatic breast cancer with symptomatic bone metastases. The choice of
agent for an individual patient depends on individual circumstances.
5.7 ENDOCRINE THERAPY
A Premenopausal women whose tumours are not shown to have absent oestrogen or
progesterone receptors should be considered for adjuvant endocrine therapy.
A In premenopausal women with advanced disease, the combination of tamoxifen plus
ovarian ablation should be offered before tamoxifen therapy alone.

A In postmenopausal women with breast cancer tamoxifen remains the treatment of choice
as initial therapy in the adjuvant setting. If there are relative contraindications to its use
(high risk of thromboembolism or endometrial abnormalities) or intolerance, an aromatase
inhibitor can be used in its place.
A Postmenopausal patients should be considered for a switch to an aromatase inhibitor
aftereithertwotothreeyearsorafterveyearsoftamoxifentherapy.
A In postmenopausal women with advanced disease, third generation aromatase inhibitors
should be considered before either tamoxifen or megestrol acetate.
