Canhelp®-Origin

Test Diagnostico per l’Identificazione dell’Origine del Tumore

Utilità di Canhelp-Origin

Canhelp-Origin è un test molecolare per l’identificazione del sito primario di un tumore metastatico,
particolarmente utile in caso di tumori scarsamente differenziati o non differenziati.

La tecnologia di Canhelp-Origin è RT-PCR quantitativa.

Il test è validato clinicamente, con un’accuratezza complessiva superiore al 90%.

E’ utile per il patologo molecolare, quando:

  • Il tumore è scarsamente differenziato o indifferenziato
  • Il campione è ridotto e ciò limita l’iter diagnostico
  • I risultati dell’IHC sono inconclusivi o contraddicono i risultati precedenti
  • È impossibile diagnosticare in modo differenziale due o più tipi di cancro

E’ utile per l’oncologo, quando:

  • Il paziente ha una storia di tumori multipli
  • si è in presenza di sedi metastatiche atipiche
  • le diagnosi cliniche e patologiche sono incoerenti
  • vi è un dubbio sulla diagnosi dopo un fallimento terapeutico

 

 

Level of evidence 1A (LoE1A)

The ESMO guidelines for early breast cancer recognize genomic tests such as EndoPredict at level 1A*.

Prospective studies

Several prospective studies* with EndoPredict have been published, confirming the results of previous retrospective studies.

Key aspects 

Long-term prospective outcome data using EndoPredict as risk stratification and chemotherapy decision biomarker in hormone receptor-positive, HER2-negative early breast cancer

Klein E. et al. Breast Cancer Res. Treat. 2024

 

  1. Distant metastasis-free survival: The low-risk EPclin group had a 5-year metastasis-free survival rate of 96.6%, compared to 85.5% in the high-risk EPclin group. High-risk EPclin patients also had a significantly higher risk of distant recurrence or mortality.
  2. Benefit of Chemotherapy: High-risk EPclin patients who received chemotherapy had a substantial improvement in 5-year disease-free survival (DFS) compared to those who did not receive chemotherapy, highlighting the effectiveness of EndoPredict in identifying patients who may benefit from chemotherapy.
  3. Menopause Status: EndoPredict has been shown to be usable for risk assessment also for pre-menopausal women.
  4. Ki67 comparison: The study showed that EndoPredict provides a more accurate estimate of prognosis than Ki-67 subtypes.

EndoPredict is a CE IVD kit

The EndoPredict test is performed on FFPE breast tumor tissue samples in your molecular laboratory.

Molecular analysis quantifies the expression of 12 genes, using messenger RNA extracted from formalin-fixed, paraffin-embedded (FFPE) material. The method uses RT-QPCR to investigate the expression of 12 genes:
• 5 genes linked to the expression of estrogen receptors: STC2, AZGP1, IL6ST, RBBP8, MGP
• 3 genes related to cell function (proliferation): BIRC5, UBE2C, DHCR7
• 4 control genes: OAZ1, CALM2, RPL37A, HBB

There are two kits available in different sizes that allow you to perform one or two tests at a time.

EndoPredict® QS UNO Kit – CE IVD (6 tests)

EndoPredict® QS DUO Kit – CE IVD (12 tests)

The total duration of the procedure is approximately 8 hours, of which 3 are operational, including the RNA extraction phase from the sample.

 

The EndoPredict report

The system uses the EPRG (EndoPredict Report Generator) interpretation and reporting software for the analysis of the 12 genes.

EPRG integrates the molecular data with information on the size of the tumor (T) and the number of positive lymph nodes (N) and generates the prognostic-predictive parameter EPclin which is the final result of the test.

The EndoPredict test report provides the following results:

  • the risk of tumor recurrence at 10 years (prognostic data)
  • the benefit of any chemotherapy (predictive data)
  • the risk of recurrence up to 15 years (long-term prognostic data)
