Just 1 risk factor further increases risk of recurrence4-9

RISK CONSIDERATIONS IN HER2+ EARLY BREAST CANCER PATIENTS

1 or more positive nodes4

  • At 10 years, 25% of patients with 1–3 positive nodes experienced recurrence

  • At 10 years, 45% of patients with ≥4 positive nodes experienced recurrence

Tumor size ≥2 cm5

  • Tumors 2 cm to 5 cm in greatest dimension were associated with a 53% increase in the risk of recurrence*

  • Tumors >5 cm in diameter were associated with an 81% increase in the risk of recurrence*

Lack of pCR6

  • Not achieving a pCR puts patients at greater risk: achieving a pCR reduced the risk of recurrence by 74% at 3 years compared with no pCR

  • Patients with HER2+ HR+ breast cancer may be less likely to achieve a pCR than patients with HER2+ HR- breast cancer

Other risk factors include:

  • Age at diagnosis7

  • High BMI8

  • Smoking9

*Compared with tumors less than 2 cm in diameter.5

BMI: body mass index; HER: human epidermal growth factor receptor; HR-: hormone receptor–negative; HR+: hormone receptor–positive; pCR: pathologic complete response.

Monoclonal antibodies have improved but not eliminated the risk of recurrence4,5,10,11

RECURRENCE RATES IN HER2+ EARLY BREAST CANCER CLINICAL TRIALS

Once distant recurrence has occurred, the disease remains incurable and patient survival is low12,13

*Recurrence refers to disease-free survival, defined as the time from randomization to the first occurrence of any of these events: recurrence of breast cancer at any site; the development of ipsilateral or contralateral breast cancer, including ductal carcinoma in situ but not lobular carcinoma in situ; second nonbreast malignant disease other than basal-cell or squamous-cell carcinoma of the skin or carcinoma in situ of the cervix; or death from any cause.4

Recurrence refers to disease-free survival, defined as the time from enrollment to documentation of the first of any of these events: local, regional, or distant recurrence of breast cancer; a contralateral breast cancer; a second primary cancer; or death as a result of any cause.5

Recurrence refers to disease-free survival, defined as the time from randomization to breast cancer recurrence, a second primary cancer (excluding contralateral ductal carcinoma in situ), or death from any cause.14

§Recurrence refers to invasive disease–free survival, defined as time from randomization to the first occurrence of any of the following events: recurrence of ipsilateral invasive breast tumor, recurrence of ipsilateral locoregional invasive breast cancer, contralateral invasive breast cancer, a distant disease recurrence, or death from any cause.11

AC: anthracycline plus cyclophosphamide; HER: human epidermal growth factor receptor; ITT: intent to treat; pCR: pathologic complete response; T: taxane; TC: taxane plus carboplatin.

Preventing CNS metastases remains a critical unmet need in HER2+ breast cancer15,16

katherine trial

(trastuzumab emtansine)

56%

of patients who experienced DISTANT recurrence had CNS metastases as the first site of recurrence (44/78)

APHINITY TRIAL

(pertuzumab)

35%

OF PATIENTS WHO EXPERIENCED DISTANT RECURRENCE HAD CNS METASTASES AS THE FIRST SITE OF RECURRENCE (49/141)

Trastuzumab emtansine did not reduce the incidence of CNS metastases.15
  • 6.1% of patients had CNS recurrence with trastuzumab emtansine vs 5.4% with trastuzumab
In patients with CNS recurrence, median OS was numerically lower in the trastuzumab emtansine arm vs trastuzumab.15
  • Median OS of 12.5 months with trastuzumab emtansine vs 14.3 months with trastuzumab
Overall, up to 50% of patients with advanced HER2+ breast cancer will develop brain metastases.17-19
CNS: central nervous system; HER: human epidermal growth factor receptor; OS: overall survival.
