Patient Profile Navigator
for all your HR+, HER2-, N0, early-stage breast cancer patients
Moving from assumed to proven chemotherapy benefit:
The clarity your patients deserve
In your clinical practice you need to make important decisions and need to consider complex questions daily for your patients:

Will my patient really benefit from chemotherapy? What is the outcome for my patient in the next 5-9 years? Should I order an Oncotype DX Breast Recurrence Score® test to better understand the underlying tumour biology of my patient’s cancer and thus be able to make a tailored chemotherapy treatment decision?
The Oncotype DX Breast Recurrence Score® test is clinically validated for
HR+, HER2-, N0/N1, early-stage breast cancer patients

The Patient Profile Navigator will provide you with N0 clinical data to help you decide whether an Oncotype DX® test would aid in making these important decisions.

Conclusion

In the absence of Oncotype DX® testing, the high chemotherapy baseline treatment rate in patients <50 years may lead to potential overtreatment1

The data from the SEER registry shows that1:

  • Patients <50 years of age with early HR+, HER2- breast cancers tend to receive more chemotherapy.
  • Therefore, the risk of chemotherapy overtreatment could increase with decreasing patient age.2

1. Griggs J Clin Oncol. 2012; 2. Sparano et al. N Engl J Med. 2018.

In TAILORx, distribution of Recurrence Score® results is consistent across age groups1

The results from the TAILORx study show that1:

  • The distribution of Recurrence Score® results does not vary with age, suggesting the tumour biology is not correlated with age.
  • Given the high chemotherapy treatment rate in patients ≤50 years,2 there is a possible risk of chemotherapy overtreatment in younger patients, if not tested.

1. Sparano et al. N Engl J Med. 2018; 2. Griggs J Clin Oncol. 2012.

The Oncotype DX® test is the only test predictive of chemotherapy, and it provides precise chemotherapy benefit estimates for patients ≤50 years2-5

The results from TAILORx and NSAPB-20 suggest that2-5:

  • A large proportion of patients ≤50 years of age do not benefit from chemotherapy.3
  • The Oncotype DX® test provides estimates of benefit from chemotherapy for patients younger ≤50 years old.4,5
  • TAILORx 12-year data observed a chemotherapy benefit in women ≤50 years with Recurrence Score® (RS) results 16-20 and high clinical risk or RS® results 21-25 regardless of clinical risk.5
  • More precisely, for this age group studies determined:
    • RS® result: 0-15: no significant CT benefit1-5
    • RS® result: 16-20: 0.6% (±2.1) CT benefit3-5
    • RS® result: 21-25: 7.8% (±3.4) CT benefit3-5
    • RS® result: 26-100: substantial CT benefit1-2

In the absence of Oncotype DX® testing, the low chemotherapy baseline treatment rate in patients >70 years may lead to potential undertreatment1

The data from the SEER registry show that1:

  • Older patients with early HR+, HER2- breast cancer tend to receive less chemotherapy.
  • Therefore, the potential of chemotherapy undertreatment may increase with patient age.

In TAILORx, distribution of Recurrence Score® results is consistent across age groups1:

The results from the TAILORx study show that1:

  • The distribution of Recurrence Score® results does not vary with age, suggesting the tumour biology is not correlated with age.
  • About 15% of patients aged >50 years have Recurrence Score® results 26-100 and may benefit from chemotherapy.

The Oncotype DX® test is the only test predictive of chemotherapy benefit, and it provides chemotherapy benefit estimates for patients1-5

The results from TAILORx and NSABP-20 suggest that1-5:

  • A large proportion of patients >50 years of age do not benefit from chemotherapy.3
  • The Oncotype DX® test provides estimates of benefit from chemotherapy by age and clinical risk groups.1-5
  • For this age group studies demonstrated:
    • RS® result: 0-25: no significant CT benefit1-5
    • RS® result: 26-100: substantial CT benefit1,2

Treatment change pre- and post-Oncotype DX® testing in routine clinical practicea,1

A sub-analysis of grade 2 patients tested in a French decision impact study demonstrated that1:

  • Oncotype DX® test use for grade 2 patients in clinical practice led to an overall reduction in chemotherapy recommendation of 60%.
  • Among the 40% of grade 2 patients who had an initial recommendation of HT, 13% (19 pts) had an escalation to CT-HT after receiving the Recurrence Score® results.
  • Among the 60% of the patients with grade 2 who were initially recommended CT-HT, 69% (156 pts) had a de-escalation to HT alone after receiving the Recurrence Score® results.

Clinical pathologic features alone do not predict Recurrence Score® results in clinical practice1

A retrospective analysis from routine clinical practice in Germany confirmed that1:

  • Real-world evidence confirms that tumour grade cannot predict the Recurrence Score® results.1
  • A majority of patients with grade 3 tumours have Recurrence Score® results 0-251 and may not benefit from adjuvant chemotherapy.2

    •  

    a Low clinical risk:
    N0, T ≤3 cm and Grade 1; N0, T ≤2 cm and Grade 2; N0, T ≤1 cm and Grade 3
    N1, T ≤2 cm and Grade 1
    High clinical risk: all other cases

The Oncotype DX Recurrence Score® assay informs chemotherapy recommendations in patients with Grade 3 tumoursa,1

A sub-analysis of grade 3 patients tested in a French decision impact study demonstrated that1:

  • Before receiving Recurrence Score® results, clinicians recommended chemotherapy to the vast majority (87%) of patients with grade 3 tumours.
  • With Recurrence Score® results they reduced chemotherapy recommendations overall by 34%.
  • There was a very significant de-escalation (38%) of CT-HT to HT alone.
  • There was an escalation (30%) to CT-HT for 6 patients that were initially recommended HT alone.

Ki-67 status is not predictive of adjuvant chemotherapy benefit1

Two independent studies from the IBCSG study group showed that1:

  • Relative treatment effect was independent of Ki-67.

1. Viale et al. J Natl Cancer Inst. 2008.

Prospective data show a distribution of Recurrence Score® results across all ranges of Ki-671

In the German prospective trial WSG plan B, Ki-67 expression was assessed centrally1:

The results show that:

  • Ki-67 values centrally assessed had only a weak to moderate correlation with the Recurrence Score® results.1
  • About 1 in 10 patients with Ki-67 values of <10% had a Recurrence Score® result 26-1001 and may benefit from adjuvant chemotherapy.2-3

Comparison of Ki-67 staining and Recurrence Score® results in clinical practice1

A retrospective analysis from routine clinical practice in Germany reported1:

  • An overall high discordance of 45% between Ki-67 (20% as cutoff) and the Recurrence Score® result (25 as cutoff).
  • A significant proportion of patients with a Ki-67 value of ≤10% result 26-1001 and may benefit from adjuvant chemotherapy.2-3

Relationship between Recurrence Score® results and Ki-671

The CLALIT real-world registry suggests that1:

  • There is weak to moderate correlation between Ki-67 values and the Recurrence Score® results.
  • A significant proportion of patients with Ki-67 values between 20-40% have Recurrence Score® results 0-25.
