malignancy

Breast cancer 27-Sep-2018

Description of condition

Breast cancer is the most common form of malignancy in

women, especially in those aged over 50 years. Established

risk factors include age, early onset of menstruation, late

menopause, older age at first completed pregnancy, and a

family history of breast cancer. The use of oral

contraceptives or hormone replacement therapy (HRT) is

also associated with an increased risk of breast cancer.

Breast cancer in men is rare. Although risk factors are not

fully understood, it may be associated with abnormalities of

sex hormone metabolism, including those caused by liver

disease or testicular trauma, genetic predisposition, and

environmental risk factors such as industrial exposure to

chronic heat.

Additional risk factors include obesity and alcohol

consumption.

942 Hormone responsive malignancy BNF 78

Immune system and malignant disease

8

Physical activity and breast-feeding protect against breast

cancer.

Non-invasive breast cancer, also known as ductal

carcinoma in situ, is when the cancer remains localised in the

ducts. However, in most cases, the cancer is invasive at the

time of diagnosis, which means that malignant cells are

liable to spread beyond the immediate area of the tumour.

Invasive breast cancer, where malignant cells spread beyond

the ducts, can be defined as early breast cancer (stage I/II),

locally advanced disease (stage III) and advanced disease

(stage IV).

Aims of treatment

Reducing mortality, increasing progression-free and diseasefree survival and improving quality of life are the main aims

of treatment, and are dependent on the stage of the disease.

Surgery and radiotherapy aim to remove the tumour mass,

whilst adjuvant drug therapy (drug treatment following

surgery) aims to reduce the risk of disease recurrence and the

risk of developing invasive disease. Neoadjuvant drug

therapy (drug treatment before surgery) aims to reduce the

size of the tumour to allow breast-conserving surgery to be

possible and to reduce axillary lymph node involvement.

Advanced breast cancer is not curable, and treatment aims to

prolong survival, relieve symptoms and improve quality of

life.

Overview

The management of patients with breast cancer involves

surgery, radiotherapy, drug therapy, or a combination of

these. The course of the disease and the therapeutic

approach vary depending on the characteristics of the

cancer. Factors such as patient age, menopausal status,

tumour size and grade, involvement of axillary lymph nodes

or skin, and the presence of hormone receptors within the

tumour, may inform the extent and aggressiveness of the

disease.g The risks and benefits of each therapy should

be discussed with the patient before being started. h

Early and locally advanced breast cancer

For operable breast cancer, treatment involves surgery to the

breast (breast-conserving surgery or mastectomy) and to the

axillary lymph nodes, with or without radiotherapy to reduce

local recurrence rates. This is often followed by adjuvant

drug therapy to eradicate the micro-metastases that cause

relapses.g In women with invasive breast cancer,

radiotherapy is recommended after breast-conserving

surgery with clear margins (no cancer cells are found at the

edges of the removed tissue), as it reduces local recurrence

rates. However, the use of radiotherapy may be omitted if

risk of local recurrence is very low and the woman is willing

to take adjuvant endocrine therapy for a minimum of 5 years.

Radiotherapy is also recommended after mastectomy in

patients with node-positive invasive breast cancer or

involved resection margins (cancer cells are found at the

edges of the removed tissue). It should also be considered in

patients with node-negative T3 or T4 invasive breast cancer.

h

Adjuvant drug therapy

Adjuvant drug therapy may include the use of

chemotherapy, endocrine therapy, biological therapy, or

bisphosphonate therapy.g The decision to use adjuvant

drug therapy should be based on the risks and benefits of

treatment, disease prognosis and predictive factors such as

oestrogen receptor (ER), progesterone receptor (PR), and

human epidermal growth receptor 2 (HER2) status of the

primary tumour.

In women with invasive breast cancer in only one breast

who have not received treatment, including the use of

neoadjuvant chemotherapy, NICE clinical guideline 101

recommends the use of the PREDICT tool to estimate

prognosis and the absolute benefits of adjuvant therapy

(www.predict.nhs.uk). h

Chemotherapy

g Adjuvant anthracycline–taxane combination

chemotherapy is recommended in patients with invasive

breast cancer who are at sufficient risk of disease recurrence

to require chemotherapy. h The choice of chemotherapy

regimen is usually guided by local policy, Cancer Alliances,

and the National Cancer Drugs Fund list.

Biological therapy

g Trastuzumab p. 885 should be offered to patients with

tumour size T1c and above HER2-positive invasive breast

cancer, in combination with surgery, chemotherapy, or

radiotherapy. It should also be considered in patients with a

smaller tumour size (T1a or T1b) depending on their comorbidities, prognosis, and possible toxicity with

concomitant chemotherapy. Cardiac function should be

regularly assessed in patients receiving trastuzumab p. 885,

and particular caution should be taken in patients with

underlying cardiac disease (consult product literature for

further details). h

Endocrine therapy

g Tamoxifen p. 953 should be used as initial adjuvant

endocrine therapy in men and premenopausal women with

oestrogen-receptor-positive invasive breast cancer. In

addition, ovarian function suppression with a gonadotropinreleasing hormone (GnRH) should be considered in

premenopausal women, taking into account the risk of

temporary menopause. hOvarian function suppression

aims to stop the production of circulating oestrogen, which

can stimulate breast cancer progression. It may be most

beneficial in women who are at sufficient risk of disease

recurrence to have been offered chemotherapy.

g In postmenopausal women with oestrogen-receptor

positive invasive breast cancer who are at medium or highrisk of disease recurrence, an aromatase inhibitor should be

given as first-line therapy. Alternatively, tamoxifen should

be given if an aromatase inhibitor is not tolerated or is

contra-indicated, or if the risk of disease recurrence is low.

h

Extended endocrine therapy

g Extended endocrine therapy (total duration longer than

5 years) with an aromatase inhibitor [unlicensed indication]

should be offered to postmenopausal women with

oestrogen-receptor-positive invasive breast cancer at

medium or high-risk of disease recurrence who have been

taking tamoxifen for 2 to 5 years. Extended therapy should

also be considered in postmenopausal women at low risk of

disease recurrence.

Extended tamoxifen therapy for longer than 5 years can

also be considered in both premenopausal and

postmenopausal women with oestrogen-receptor-positive

invasive breast cancer. h

Endocrine therapy for ductal carcinoma in situ

g Following breast-conserving surgery, endocrine

therapy should be offered to women with oestrogen-positive

ductal carcinoma in situ, if radiotherapy is recommended but

not given. If radiotherapy is not recommended, the use of

endocrine therapy should also be considered. h

Bisphosphonate therapy

Zoledronic acid p. 732 and sodium clodronate p. 731 have

been shown to improve disease-free survival and overall

survival in postmenopausal women with node-positive

invasive breast cancer. However, there is insufficient

evidence to recommend their use in premenopausal women.

g Intravenous zoledronic acid [unlicensed indication] or

oral sodium clodronate [unlicensed indication] should be

offered to postmenopausal women with lymph-nodepositive invasive breast cancer. Treatment should be

considered in those with lymph-node-negative invasive

breast cancer who are at high-risk of recurrence. h

BNF 78 Hormone responsive malignancy 943

Immune system and malignant disease

8

g Bisphosphonate therapy is also recommended in

women at high-risk of osteoporosis due to the use of

aromatase inhibitors in postmenopausal women, or in

women with treatment-induced premature menopause. For

further information, see Guidance for the management of

breast cancer treatment-induced bone loss: a consensus

position statement from a UK expert group, 2008. h

Neoadjuvant drug therapy

Neoadjuvant drug therapy may involve the use of

chemotherapy or endocrine therapy.

Chemotherapy

g Neoadjuvant chemotherapy should be offered to reduce

tumour size in patients with oestrogen-receptor-negative

invasive breast cancer. In patients with oestrogen-receptorpositive invasive breast cancer, chemotherapy should be

considered. In patients with HER2-positive invasive breast

cancer, neoadjuvant chemotherapy should be offered in

combination with trastuzumab p. 885 and pertuzumab

p. 880.

A chemotherapy regimen containing both a platinum

[unlicensed indication] and an anthracycline should be

considered in patients with triple-negative invasive breast

cancer (oestrogen-receptor-negative, progesterone-receptor

negative and HER2-negative). h

Endocrine therapy

g If chemotherapy is not indicated, neoadjuvant

endocrine therapy should be considered as an alternative in

postmenopausal women with oestrogen-receptor-positive

invasive breast cancer. hChemotherapy and endocrine

therapy are equally effective in postmenopausal women in

terms of breast-conservation and shrinking of the tumour.

Although chemotherapy is more effective than endocrine

therapy at shrinking the tumour in premenopausal women,

some tumours may respond to endocrine treatment.

Advanced breast cancer

Treatment of advanced breast cancer depends on the

patient’s treatment history, disease severity, and oestrogen

receptor and HER2 status.

Endocrine therapy

g For the majority of patients with oestrogen-receptorpositive advanced breast cancer, endocrine therapy is

recommended as first-line treatment. Aromatase inhibitors

should be offered to postmenopausal women with no

previous history of endocrine treatment, or to those

previously treated with tamoxifen p. 953.

Tamoxifen in combination with ovarian function

suppression should be offered as first-line treatment to preand perimenopausal women with oestrogen-receptorpositive advanced breast cancer not previously treated with

tamoxifen.

Ovarian function suppression should be offered to preand perimenopausal women who have had disease

progression despite treatment with tamoxifen.

Tamoxifen should be offered as first-line treatment to

men with oestrogen-receptor-positive advanced breast

cancer. h

Chemotherapy

g Chemotherapy should be offered as first-line treatment

in patients with oestrogen-receptor-positive advanced

breast cancer that is imminently life-threatening or requires

early relief of symptoms because of significant visceral organ

involvement. Once chemotherapy treatment is completed,

endocrine therapy should be offered. hThe choice of

chemotherapy regimen is usually guided by local policy,

Cancer Alliances, and the National Cancer Drugs Fund list.

Biological therapy

g Trastuzumab is recommended for the treatment of

HER2-positive advanced breast cancer. It is used in

combination with paclitaxel p. 925 in those who have not

received chemotherapy for metastatic breast cancer, and as

monotherapy for patients who have received at least two

chemotherapy regimens for metastatic breast cancer (see

trastuzumab National funding/access decisions). h

Bisphosphonate therapy

g The use of bisphosphonates should be considered in

patients with metastatic breast cancer to reduce pain and

prevent skeletal complications of bone metastases. h

Familial breast cancer

g Chemoprevention should be offered to all women who

have been identified as being at high-risk of developing

breast cancer. Chemoprevention should also be considered

in women at moderate-risk. Other strategies to reduce breast

cancer risk should also be considered, for example bilateral

mastectomy or bilateral oophorectomy. Women who were at

high-risk of breast cancer and have undergone a bilateral

mastectomy should not receive chemoprevention. h

Treatment options for chemoprevention

g Chemoprevention should only be continued for 5 years.

Tamoxifen [unlicensed indication] is recommended for

premenopausal women who do not have a history of, or

increased risk of thromboembolic disease or endometrial

cancer.

Anastrozole p. 954 [unlicensed indication] is

recommended in postmenopausal women who do not have

severe osteoporosis, see Osteoporosis p. 725. In women who

have severe osteoporosis, or who do not wish to take

anastrozole, treatment with tamoxifen can be given,

provided there is no history, or increased risk of

thromboembolic disease or endometrial cancer.

Alternatively, raloxifene hydrochloride p. 754 is an option

[unlicensed indication] in postmenopausal women with a

uterus who do not wish to take tamoxifen, unless there is a

history or increased risk of thromboembolic disease. h

Treatment of menopausal symptoms

g Some treatments used in the management of breast

cancer, such as tamoxifen or ovarian function suppression

may lead to menopausal symptoms or early menopause, and

women should be counselled about these side-effects prior

to starting any of these treatments.

Women diagnosed with breast cancer should discontinue

their hormone replacement therapy (HRT) because of

possible tumour stimulation and interference with adjuvant

endocrine therapy. HRT should not be offered routinely to

women with menopausal symptoms if they have a history of

breast cancer; however, in exceptional circumstances, HRT

can be offered to women with severe menopausal symptoms

once the associated risks have been discussed.

Selective serotonin re-uptake inhibitor (SSRIs)

antidepressants may be offered to relieve menopausal

symptoms such as hot flushes in women with breast cancer

who are not taking tamoxifen. hClonidine hydrochloride

p. 145, venlafaxine p. 368 [unlicensed indication] and

gabapentin p. 315 [unlicensed indication] are sometimes

used for the treatment of hot flushes in women with breast

cancer after discussion with the patient and information

given about side effects.

Prostate Cancer 31-May-2016

Description of condition

Prostate cancer is the most common form of cancer affecting

men. The main risk factors are age (most cases being

diagnosed in men over 65 years of age), ethnicity (more

common in black African-Caribbean men), and a familial

component. Prostate cancer is usually slow-growing and

asymptomatic at diagnosis, however, the presenting

symptoms of advanced disease are usually urinary outflow

obstruction, or, pelvic or back pain due to bone metastases.

Treatment decisions are guided by baseline prostate specific

antigen (PSA) levels, tumour grade (Gleason score), the stage

of the tumour, the patient’s life expectancy (based on age

and comorbid conditions), treatment morbidity, and patient

preference.

Aims of treatment

In early or locally advanced prostate cancer, radical

treatment aims to eliminate the malignancy. In metastatic

disease, drug therapy is aimed at prolonging survival and

reducing symptoms.

Drug treatment

Treatment options for patients with prostate cancer include

active monitoring, radical prostatectomy, external beam

radiotherapy, and brachytherapy. Hormone therapy

(androgen deprivation or anti-androgens) is the primary

treatment for metastatic prostate cancer, but is also

increasingly being used for patients with locally advanced,

non-metastatic disease.

In patients with localised prostate cancer, the choice of

treatment is guided by whether the disease is considered

low, intermediate, or high risk according to the Gleason

score, the serum PSA level, and the tumour stage.

Localised or locally advanced prostate cancer

g In patients with low-risk localised prostate cancer,

and those at intermediate risk who decline radical

treatments (prostatectomy or radiotherapy), active

monitoring is a suitable option. This involves close

monitoring to avoid unnecessary treatment until disease

progression occurs (or until the patient requests treatment).

In patients with intermediate-risk or high-risk localised

prostate cancer (when there is a realistic prospect of longterm disease control) and in those with locally advanced

disease, radical prostatectomy or radical radiotherapy

should be offered. Other treatment options include a

combination of radical radiotherapy and androgen

deprivation therapy, consisting of 6 months of androgen

deprivation therapy before, during or after radiotherapy.

Pelvic radiotherapy should be considered in those with

locally advanced prostate cancer who have a higher than

15% risk of pelvic lymph node involvement and are to

receive neoadjuvant hormonal therapy.

Androgen deprivation therapy involves the use of a

luteinising hormone-releasing hormone (LHRH) agonist

(buserelin p. 738, goserelin p. 739, leuprorelin acetate p. 740,

or triptorelin p. 741), or bilateral orchidectomy, which

removes the supply of endogenous hormone. Androgen

deprivation therapy may be continued for up to 3 years in

patients with high-risk localised prostate cancer.

Patients should be informed about the side-effects of

treatment, particularly urinary and sexual dysfunction, loss

of fertility, radiation-induced enteropathy, and hot flushes.

Although there is limited evidence, intermittent therapy

may be considered for patients who are having long-term

androgen deprivation therapy, to reduce drug toxicity.

Tumour flare, due to an initial surge in testosterone

concentrations, has been reported in the initial stages of

treatment with androgen deprivation therapy and

prophylactic anti-androgen therapy (such as cyproterone

acetate p. 770) may be added.

Medroxyprogesterone acetate p. 810 [unlicensed

indication] can be used, initially for up to 10 weeks, to

manage troublesome hot flushes caused by long-term

androgen suppression; cyproterone acetate is an alternative

if medroxyprogesterone acetate is not effective or not

tolerated.

Patients who experience a reduction in libido and loss of

sexual function should have access to specialist erectile

dysfunction services and be considered for treatment with a

phosphodiesterase type-5 inhibitor.

Osteoporosis and fatigue may also be a problem with

androgen deprivation therapy. A bisphosphonate can be

offered to men who have osteoporosis; denosumab p. 734 is

an alternative if bisphosphonates are not appropriate.

Gynaecomastia can occur with long-term (longer than

6 months) bicalutamide p. 947 treatment. Prophylactic

radiotherapy (within the first month of treatment), or weekly

tamoxifen p. 953 [unlicensed indication], if radiotherapy is

unsuccessful, can be considered. h

Metastatic prostate cancer

g Bilateral orchidectomy should be offered to all patients

with metastatic prostate cancer as an alternative to

continuous LHRH agonist treatment. Anti-androgen

monotherapy with bicalutamide [unlicensed indication] can

be offered to those who are willing to accept the adverse

impact on overall survival and gynaecomastia in the hope of

retaining sexual function. However, if satisfactory sexual

function is not maintained, stop bicalutamide and start

androgen deprivation therapy.

Abiraterone acetate p. 946 (in combination with

prednisone or prednisolone p. 678) and enzalutamide p. 947

are both recommended as options for the treatment of

castration-resistant metastatic prostate cancer in patients

whose disease has progressed during or after treatment with

a docetaxel p. 924-containing chemotherapy regimen.

In patients who develop hormone-relapsed metastatic

tumour, chemotherapy with docetaxel can be used. It is

recommended to stop the treatment with docetaxel after

10 cycles, or if severe adverse events occurred, or if there is

evidence of disease progression.

Abiraterone acetate (in combination with prednisone or

prednisolone) is also recommended as an option for treating

metastatic hormone-relapsed prostate cancer in patients

who have no or mild symptoms after androgen deprivation

therapy has failed, and before chemotherapy is indicated.

In patients with hormone-relapsed prostate cancer, a

corticosteroid, such as dexamethasone p. 675, can be offered

as third line therapy, after androgen deprivation therapy and

anti-androgen therapy. h
