4 1.0 Oncology Provision 1.1 Purpose This document has been written to provide guidance on the treatment of breast cancer in the Kent & Medway Cancer Network. Radiotherapy schedules are as defined in the Kent Oncology Centre Quality System Clinical Protocols. See network chemotherapy prescribing proformas for details of chemotherapy / anti-cancer regimens. All patients will be considered for entry into a clinical trial (see appendix C). All patients should be discussed within a multidisciplinary team meeting before commencing initial treatment. All chemotherapy regimens listed within this document are delivered at either Maidstone and Tunbridge Wells NHS Trust, Dartford and Gravesham NHS Trust, Medway NHS Foundation Trust or East Kent Hospitals University NHS Foundation Trust. Please note, some of the drugs / doses recommended within this document are outside of the UK licensed marketing authorisation. 1.2 Details The following information is needed at the time of referral: Age and menopausal status. Performance status. Full histology including grade and excision margins in early disease. ER and preferably PgR status. HER2 status. Recommendations for staging and pre-chemo investigations: All patients should have blood tests (U&E, LFTs, FBC) and chest X-ray. Patients receiving an anthracycline should have baseline ECG. Consider MUGA or ECHO pre-anthracycline for patients with cardiac history. Patients receiving Trastuzumab should have MUGA / ECHO scans performed before and during treatment, see appendix B. Patients with T3, T4, N2 tumours and bilateral tumours should be fully staged to exclude liver, lung and bone metastases with a CT and bone scan. 1.3 Ovarian protection preservation of fertility For premenopausal women anxious to protect their fertility, early referral to a fertility specialist should be arranged for a full discussion of options. If no definitive fertility treatment is chosen, there is some evidence to suggest 4 weekly Zoladex 3.6mg sc started 10 days pre c1 of chemotherapy and continued throughout, may help preserve fertility.

5 2.0 Adjuvant chemotherapy Adjuvant chemotherapy should be discussed with patients according to the risk of relapse based on the most recent EBCTGG overview and other consensus documents e.g. St. Gallen. is considered an acceptable tool to aid the decision-making process when discussing the risks and benefits of adjuvant chemotherapy with patients (ASCO 2004). Adjuvant chemotherapy should be started as soon as clinically possible within 31 days of completion of surgery. 2.1 Low Risk Patients considered to be in a group where the absolute benefit of chemotherapy is so small or unproven that its routine use is clinically not recommended. These patients include the following: Patients over 70 years (discussion may be warranted for fit patients over 70 with multiple poor risk factors). Patients with all of the following factors: Negative lymph nodes. No vascular or lymphatic invasion. Grade I/II. Tumour 2cm. ER positive. 35 yrs HER2-ve Pre and post-menopausal (N1-3) patients who are ER+ HER2- and node- and where patient and oncologist are undecided about the benefit of chemotherapy, may be suitable for Oncotype DX testing (funding required - through NHSE for Trusts signed up to CQUIN) 2.2 High Risk Adjuvant chemotherapy confers an absolute survival benefit for patients with the following risk factors: Node positive. Grade III. Vascular or lymphatic invasion. ER negative. Tumours 2 cm. Patients 35yrs HER2 +ive Acceptable chemotherapy regimens include: AC x4 FEC 60 x 6. FEC 75 x 6 F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 5 of 26

6 FEC 100 x 3 followed by Docetaxel x3 for node positive E 90 C 600 every 3 weeks x 4 followed by accelerated Paclitaxel 175mg/m 2 every 2 weeks x4 CMF X 6 Classical/Bonnadonna (reserved for patients with a cardiac history or those patients insisting on a regimen that is less likely to cause alopecia), using oral cyclophosphamide. Epirubicin x 4 followed by CMF(oral) x 4 TC (Docetaxel and Cyclophosphamide) X 4 for those node positive patients for whom an anthracycline is contraindicated or for low risk HER2+ive node negative patients (algorithm deviation). TCH (Docetaxel,Carboplatin and Trastuzumab) x 6 for high risk HER2+ive patients who are not suitable for an anthracycline. Myocet (liposomal doxorubicin) as a substitute for an anthracycline in patients with a cardiac history or prior anthracycline exposure (funding approval required) Abraxane (albumin paclitaxel) may be used as an alternative for patients who have documented taxane hypersensitivity. Weekly paclitaxel can be considered for otherwise low risk but HER2+ive patients High risk, node negative patients e.g. triple negative or HER2 +ve patients should be considered for a docetaxel containing regimen e.g. FEC-T For details on chemotherapy regimens and pre-treatment parameters, please refer to the Network Chemotherapy Prescription Proformas. Triple Negative Tumours It should be remembered that ER PR and HER2 negative tumours carry a worse prognosis and are a population often suitable for entry into clinical trials. Also triple negative patients under 35 years are suitable for referral for BRCA testing whatever their family history. 3.0 Adjuvant hormone therapy (for hormone receptor positive patients, ER and/or PgR Adjuvant endocrine therapy should be started the day after completion of radiotherapy. For patients with ER-positive advanced breast cancer who have neoadjuvant chemotherapy, offer endocrine therapy following the completion of chemotherapy. 3.1 Tamoxifen Patients with hormone receptor positive tumours, who are considered to be either low risk or in whom an aromatase inhibitor is not tolerated or contraindicated, should commence tamoxifen 20 mg daily for 5 years (after completion of chemotherapy and radiotherapy where indicated). Patients should be considered for extension of Tamoxifen for up to 10 years where risk / benefit has been discussed with the patient. The initiating physician must warn the patient about the small risk of endometrial cancer and venous thrombosis, and document that this has been done. For worrying symptoms, rapid access referral to Gynaecology should be arranged. F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 6 of 26

7 3.2 Aromatase Inhibitors (AIs) NB see appendix A for assessment of bone loss. AIs are only licensed in post menopausal women. When given pre-menopausally they cause heavy vaginal bleeding and can even induce ovulation and thus pregnancy. There is no good data on how to reliably define the menopause in patients; particular care should be taken in young women post chemotherapy in whom ovarian function can recover even after 2 years, despite amenorrhoea. AIs should not be prescribed to women under 40 who become amenorrhoeic following chemotherapy. It is mandatory for women under 56 to check the FSH at least (and preferably LH as well oestradiol is unhelpful in the presence of Tamoxifen); FSH should be at least 35 with amenorrhoea for at least a year. Take advice from local laboratories. Due to the small but increased risk of cardiovascular events on AIs, cardiovascular risk should be evaluated when considering all AIs and monitoring of lipids performed if appropriate. Primary care physicians and surgeons should be encouraged to report new cardiac events on AIs for discussion with oncologists if required (NEJM 353, 2005) Management of side-effects: The side effects of AIs that are more common than Tamoxifen are arthralgia and osteoporosis. Glucosamine may help the arthralgia. Patients who can t tolerate AIs can go back to Tamoxifen. All patients on adjuvant AI s should have a bone density scan booked at the beginning of treatment and this is the responsibility of the initiating physician (see section 9.0 and appendix A). Oncologists are available to aid in the medical management of AIs. 3.3 Aromatase inhibitors: initial therapy Anastrozole and Letrozole Initial adjuvant therapy with anastrazole or letrozole should be offered to all women who are not considered to be at low risk or those with contraindications to tamoxifen, i.e. previous thromboembolic episode or endometrial hyperplasia and intolerance to Tamoxifen. Low risk may be defined as a better than 93% 10 year predicted survival. Adjuvant Letrozole may be considered in patients who achieve a good partial or complete clinical response to neoadjuvant Letrozole. 3.4 Aromatase inhibitors: switch therapy A switch from Tamoxifen to an aromatase inhibitor should be considered in all appropriate women after 2/3 years of taking Tamoxifen. Exemestane and Anastrozole are licensed for this indication. Patients with relative contraindications to AIs, e.g. osteoporosis and cardiovascular disease may need to remain on Tamoxifen. The process of identifying these patients and investigations required, e.g. DEXA, should be discussed with the surgical teams involved (NICE Nov 2006, London Cancer New Drugs Group Oct 2005, Jonat SABCS 2005). A switch from Letrozole to Tamoxifen after 2-3 years may also be considered (BIG 198). F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 7 of 26

8 3.5 Aromatase inhibitors: extended therapy Letrozole Letrozole should be considered for node positive patients who have completed 5 years adjuvant Tamoxifen. This should be given for a minimum of 3 years (NICE Aug 2006, London Cancer New Drugs Group Oct 2005, Goss SABCS ). 3.6 Goserelin Monthly Goserelin (3.6mg s/c) for up to 5 years in combination with Tamoxifen or Exemestane can be considered for intermediate or high risk women under the age of 45 with ER positive tumours who continue to menstruate following adjuvant chemotherapy. In pre-menopausal patients with low-risk ER positive cancers a combination of Goserelin and Tamoxifen may be considered as a substitute to chemotherapy. NB see appendix A for assessment of bone loss. 4.0 Adjuvant Trastuzumab This should be considered for all HER2+ive patients that are eligible according to NICE guidance. Full guidance on treatment should follow NCRI Guidelines (Dec 2005), and NICE The KMCN guidelines on managing cardiac toxicity for patients receiving trastuzumab should be followed (see Appendix B). Trastuzumab should be initiated at the same time as Docetaxel (ie following 3 cycles of FEC) Testing and clinical pathways should follow those presented at the DOG. Trastuzumab may be given sc or iv The use of Trastuzumab in conjunction with radiotherapy should be discussed on an individual patient basis and is at clinical oncologist s discretion. 5.0 Post-operative radiotherapy Adjuvant radiotherapy should be started as soon as clinically possible within 31 days of completion of surgery. Post-operative radiotherapy to the conserved breast should be considered for patients with: Invasive carcinoma of the breast. For high risk, intermediate to high grade DCIS, see section 12.0 A radiotherapy boost to the tumour bed should be considered for patients: With a close radial margin (<2mm). F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 8 of 26

9 Age < 40 years. Deep margin <1mm. Patients who have received neo-adjuvant treatment. It may also be considered for: Large grade 3 tumour Lymphovascular invasion Patients under 50 yrs Post-operative chest wall radiotherapy is recommended to patients with one or more major criteria and two or more minor criteria. Major criteria: pt3 (>50mm). Histologically proven positive or close (<1mm) deep margin. 4 or more positive axillary nodes. Minor criteria: 1-3 positive axillary nodes Lymphovascular invasion. Grade 3. It may also be considered where margins are involved with DCIS Post-operative radiotherapy to the supraclavicular fossa can be considered where: - 4 or more axillary nodes are involved - 1 node is clinically radiologically or pathologically involved prior to neo-adjuvant therapy - The apical axillary node is involved - T3 tumours with 1-3 axillary nodes involved Post-operative radiotherapy to the axilla should be reserved for patients with: Residual macroscopic disease at operation. No axillary surgery but deemed to be at medium or high risk of axillary nodal involvement See Radiotherapy in breast cancer protocol for details of dose and fractionation available via Kent Oncology Centre Quality Management System. 6.0 Neoadjuvant chemotherapy Neoadjuvant chemotherapy may be considered for: Large tumours felt to necessitate mastectomy at diagnosis in which downstaging may facilitate breast conserving surgery (Fisher 1997). F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 9 of 26

10 Poor prognosis tumours unlikely to be suitable for breast conserving surgery but where surgery may delay adjuvant chemotherapy. Inflammatory or locally advanced breast cancer. Acceptable chemotherapy regimens include: o FEC-T ie (3 x FEC 100 followed by 3 x docetaxel) o FEC 75 (or FEC 60 in less fit patients) x6. o AC x6. o o Docetaxel x 6 where an anthracycline is contraindicated Abraxane (albumin paclitaxel) may be used as an alternative for patients who have documented taxane hypersensitivity. Recommended management plan: Clinical assessment before each cycle of chemotherapy to exclude disease progression. Radiological reassessment (preferably with breast ultrasound) after 3 cycles. Node positive patients should be considered for treatment with FEC-T Node negative patients should be treated with FEC 75 (or FEC 60 in less fit patients) and reassessed after cycle 3. Those patients with a complete or near complete response should continue to 6 cycles. Patients who show a partial response, stable or progressive disease when reassessed at cycle 3 should be switched to Docetaxel (75 or 100 mg/m 2 ) for 3/4 cycles (in accordance with the advanced breast cancer clinical guideline). o Patients with high risk node negative tumours should be considered for treatment with FEC-T (funding agreement required, funding negotiations in progress). Proceed to definitive surgery or radiotherapy after chemotherapy where appropriate. Adjuvant hormone treatment as indicated. There is no evidence to support the use of further adjuvant chemotherapy for pathologically node positive patients after neoadjuvant chemotherapy. Trastuzumab (sc or iv) is documented to increase pcr rate so should be added with the 1 st docetaxel. 7.0 Neoadjuvant endocrine therapy Neoadjuvant endocrine therapy may be considered for patients with ER positive tumours in whom chemotherapy is contraindicated. Letrozole for post-menopausal patients (Ellis 2003). Tamoxifen is appropriate for: Pre-menopausal patients. Post-menopausal patients in whom aromatase inhibitors are contraindicated.

11 8.0 Endocrine treatment in advanced disease 8.1 Postmenopausal Anastrozole or Letrozole should be used first line Subsequent lines of therapy may include: Exemestane Tamoxifen (including rechallenging patients treated with adjuvant Tamoxifen). Fulvestrant (Due to the changes in funding streams from April 2013, discussions around the use of this drug are on-going and funding approval is required before a patient is initiated on treatment, funding not available through NCDF). Megesterol Acetate. Everolimus & Exemestane (funding approval required) is indicated for the treatment of hormone receptor-positive, HER2/neu negative advanced breast cancer in postmenopausal women without symptomatic visceral disease after recurrence or progression following a non-steroidal aromatase inhibitor and Tamoxifen (patient should not have received previous Exemestane). 8.2 Premenopausal Goserelin 3.6mg + Tamoxifen (for pre-menopausal patients who have not received Tamoxifen for 6 months (Klijin 2001). 9.0 Systemic Anti-Cancer Therapy in advanced disease 9.1 First line metastatic therapy For details on chemotherapy regimens and pre-treatment parameters, please refer to the Network Chemotherapy Prescription Proformas HER-2 positive patients If patient suitable for triple therapy consider docetaxel plus tratuzumab plus pertuzumab (funding approval required for pertuzumab). Subcutaneous trastuzumab when used within the license may be used in place of intravenous trastuzumab in the metastatic setting. Subcutaneous trastuzumab is not to be used in place of iv in the pertuzumab/ trastuzumab/ docetaxel regimen. Taxane (depending on performance status and LFTs) plus Trastuzumab. Alternative treatment regimens include: Vinorelbine plus Trastuzumab. FEC 75 if not given adjuvantly. F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 11 of 26

12 Patients not fit to receive chemotherapy should receive single agent Trastuzumab. If patients have progressed within 6 months of completing treatment for early stage disease and have received previous treatment with trastuzumab and a taxane, and have a PS of 0-1, consider trastuzumab emtansine (funding approval required). Lapatinib could be considered if not fit for chemotherapy (funding approval required). N.B. Removed from the CDF list on 12 th March HER2 negative patients FEC 75 (or 60 depending on performance status) if not given adjuvantly. Docetaxel (depending on performance status and LFTs). Docetaxel in combination with Capecitabine should be considered for very fit young patients requiring a rapid response e.g. for life-threatening visceral metastases. Gemcitabine and Paclitaxel. Patients not fit to receive Docetaxel should receive 2 nd or 3 rd line drugs shown below Triple negative patients: Bevacizumab with weekly Paclitaxel may be considered as first or second line treatment for metastatic disease (funding approval required). 9.2 NICE-approved 2nd or 3rd line treatments: Capecitabine monotherapy - continue treatment until disease progression or unacceptable toxicity. Vinorelbine monotherapy Anti-HER2 therapy beyond progression, lapatinib & trastuzumab emtansine NICE guidance states that trastuzumab should be discontinued at the time of disease progression outside of the central nervous system (CNS). Trastuzumab should be continued if disease progression is within the CNS alone. Trastuzumab (iv & sc), pertuzumab and trastuzumab emtansine (Kadcyla ) may be continued if progression is within the CNS alone. Lapatinib in combination with capecitabine for HER2 positive patients may be considered for patients whose disease progresses following prior therapy for metastatic disease, (including anthracyclines (or anthracyclines contraindicated), taxanes and trastuzumab - funding approval required). N.B. Removed from the CDF list on 12 th March 2015 F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 12 of 26

13 If patients have progressed during or after the most recent treatment for HER2 positive advanced stage disease, have received previous treatment with trastuzumab and a taxane, and have a PS of 0-1, consider trastuzumab emtansine (funding approval required). 9.3 Subsequent lines of therapy: Weekly Paclitaxel (80 mg/m 2 ). Gemcitabine and Carboplatin. CMF or other Anthracycline based chemotherapy if appropriate. Myocet (liposomal doxorubicin - funding approval required) Abraxane (paclitaxel albumin) Eribulin (funding approval required). Vinorelbine (oral) and Capecitabine 10.0 Bisphosphonates & denosumab for bone metastases Bisphosphonates reduce skeletal morbidity associated with bone metastases (Hillner et al, 2000; Lipton et al, 2000). All patients with bone metastases should be considered for treatment, especially those: Patients with lytic bone metastases on plain radiographs. Patients with symptomatic bone metastases (with appropriate use of palliative radiotherapy and analgesics). Patients who have suffered a previous skeletal event (pathological fracture, previous radiation to a painful bone metastasis). Regular dental assessment is required to minimise the risk of osteonecrosis of the jaw. Choice of drug: Denosumab is recommended as an option for preventing skeletal-related events in adults with bone metastases from breast cancer if bisphosphonates would otherwise be prescribed. (Delivery pathway for and funding thereof is still under discussion in some areas of Kent & Medway). Zoledronic acid is more effective than Pamidronate at reducing skeletal complications (Rosen et al, 2001). Oral bisphosphonates (Clodronate or Ibandronic acid) may be considered for patients with poor venous access or intolerance to intravenous bisphosphonates or patients on oral chemotherapy. Ibandronic Acid Pamidronate may be given 3 or 4-weekly (with or without chemotherapy). Reference: Appendix D: Bisphosphonate guidelines incorporating prescribing in renal impairment. F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 13 of 26

14 11.0 Use of antibiotics and GCSF Prophylactic use of antibiotics is not recommended routinely in view of the risk of antibiotic resistant infections. Prophylactic use of GCSF at clinical discretion after a neutropenic episode should be considered in order to maintain dose intensity and prevent delay in adjuvant chemotherapy regimens. GCSF should be given as primary prophylaxis with the FEC100 / Docetaxel regimen. See KCMN GCSF guidelines for further information. For further details, please see Network Chemotherapy Prescribing Proformas Management of DCIS Consider mastectomy for multi-focal DCIS. Complete local excision with >2mm surgical margins is recommended for localised DCIS (currently under review). The benefits and risks of post complete local excision radiotherapy should be discussed with patients with intermediate or high grade DCIS. The routine use of adjuvant Tamoxifen or an Aromatase inhibitor is not recommended in patients with DCIS. In selected high risk cases, ER testing and use of tamoxifen may be considered Management of Male Breast Cancer Oncological treatment for male breast cancer should not differ from that of female cancer. The only exception is that tamoxifen should be used first line to men with oestrogen receptor positive advanced breast cancer. Aromatase inhibitors should be used with caution in men. There is an association between male breast cancer and BRCA inheritance and careful family history should be recorded with appropriate genetic referral Use of the Mirena coil in patients with oestrogen receptor positive tumours Due to the lack of safety data, patients with oestrogen receptor positive breast cancer that have a Mirena coil in situ should have the device removed. Occasionally it may be used if no alternative method of controlling gynaecological symptoms exists, after an appropriate discussion of risks and benefits with the patient, oncologist and gynaecologist.

15 Appendix A: Assessment of bone loss See algorithms 1 and 2 below on the management of bone loss in early breast cancer Patients with early invasive breast cancer should have a baseline dual energy X-ray absorptiometry (DEXA) scan to assess bone mineral density if they: Start adjuvant aromatase inhibitors Have treatment-induced menopause under 45 years Start ovarian ablation / suppression therapy It is the responsibility of the initiating doctor to arrange a baseline DEXA scan and then to communicate the results of the scan to the patient and the GP. It should be made clear when the next scan is due and who is to arrange it. Algorithms for managing bone health exist (NCRI Breast Study Group and National Osteoporosis Society Guidelines 11/2007). For MTW and Medway, if the planned duration of an AI is stated on the form, Dr Ryan and Dr A Costa will usually advise whether a repeat scan is indicated and when. Other units may need to follow the algorithms below. If it is unclear following first DEXA result when the next scan is due, the general rule is 2 years if there is no significant osteopenia. If there is borderline osteoporosis at any point, advice should be sought from the local osteoporosis specialist. AIs can often still be given following advice with bisphosphonates and calcium supplementation. As trials have reported increase in cardiac events and lipids, patients should report any new cardiac events whilst on an AI and medical advice sought if concerned when starting or continuing an AI.

18 Appendix B: KMCN guidelines on managing cardiac toxicity for patients receiving trastuzumab Guidelines for patients receiving trastuzumab in the adjuvant setting These guidelines have been reproduced from recommendations made by Jones et al BJC (2209) 100; The same monitoring modality should be used throughout the course of treatment and, where possible, this should also include the same operator, machine, and calculation algorithm. Each institution should establish a normal range for the methods used. On the basis that an echocardiogram exposes the patient to less radiation and is usually less expensive than a MUGA scan, the NOG recommend this as the method used to assess cardiac function. ECHOs are reported as a range not an absolute figure, but it is generally accepted that the lower limit of normal (LLN) for cardiac function when measured by an ECHO is 55%. Patients developing signs and symptoms of heart failure should have their trastuzumab treatment interrupted, have ACE inhibitor therapy initiated by the oncologist and be referred to a cardiologist. Investigation and treatment is recommended in accordance with present guidelines (NICE, 2003; Bonow et al 2005; Swedberg et al 2005). It is the prescriber s responsibility to check that the ECHO/MUGA is satisfactory before continuing treatment. An ECHO/ MUGA should be carried out at the following timepoints: 1. Pre cytotoxic chemotherapy 2. Pre trastuzumab 3. Pre cycle 7 (4 months) 4. Pre cycle 12 (8 months) 5. At the end of treatment IF patients required cardiovascular intervention during treatment o The minimum number of LVEF assessments when following this recommendation is 4 compared with 5 previously NB When an ECHO is used to measure cardiac function, LLN can be assumed to be 55%. For MUGA scans, the LLN for the institution should be used. F:\Breast proformas Feb 15\Oncological_treatment_of_Breast_Cancer_v19 FINAL.doc Page 18 of 26

19 Guidelines for patients receiving trastuzumab in the metastatic setting Cardiac function should be monitored at baseline (ECHO/MUGA and ECG) and then every 6 months (ECHO or MUGA) during treatment or as clinically indicated. Follow traffic light system outlined above ( during trastuzumab ).
