OncoDiscover® CTC Test provides a potent real-time monitoring system that will help in understanding the spread of cancer and the effectiveness of therapy.

Case Studies

Below are some of the patient case-studies:

Case Study 01

Patient Details

  • Female

  • 74 yrs 

Clinical Presentation

  • Ca Breast

  • pT2pNO HR+/ HER2–

Clinical History

  • Patient underwent surgery.

  • We advised ONCOTYPE Dx but patient was unaffording.

  • We needed to decided between adjuvant chemotherapy and hormonal therapy.


Test Result

  • 4 CTCs were found with 1 CTC Cluster indicating highly aggressive disease.

  • Given her age – it was difficult to tolerate chemo.

  • 4# TC – hormonal therapy X 7.5 yrs

Clinical Outcome

Case Study 02

Patient Details

  • Male

  • 45 yrs 

Clinical Presentation

  • CA rectum

Clinical History

  • NACT+RT – Sx- CT (delayed due to myelosuppression).

  • PET Scan and CTC test done at end of therapy.


Test Result

  • 4 CTCs were found with 1 CTC Cluster indicating highly aggressive disease.

  • PET Scan confirmed multiple liver mets.

  • Patient underwent surgery.

  • Patient was unaffording for chemo and expired shortly.

Clinical Outcome

Case Study 03

Patient Details

  • Female

  • 60 years 

Clinical Presentation

  • CA Breast

    ER-/PR-/HER2 3+

Clinical History

  • Sx-L.MRM-pT2N0

  • CHEMO-6 #TCH +2 # Herceptin (no funds)- on f/u.

  • PET Scan and CTC test suggested.


Test Result

  • 2 CTCs were found indicating residual disease.

  • PET Scan confirmed liver mets.

  • Meta analysis by TMH suggests that 6 months Herceptin is equal to 12 months.

  • In this particular case, 6M of Herceptin was not enough as patient developed liver mets.

Clinical Outcome

    Suspicious lung nodules on PET SCAN

Clinical History

  • Sx –RT.MRM- pT2N2MO

  • CHEMO- ACX 4- TH X4 – Herceptin x 17 doses

  • CTC test was done post surgery and post chemotherapy.

Test Result


  • 2 CTCs were found Surgery.

  • 0 CTCs were found post chemotherapy.

  • After 17 cycles of Herceptin, since CTC and PET was normal, hence we stopped at 1 yr of therapy.

  • 6 #CT – PACLI-CARBO, counselled but PARPi not available hence didn't go for germline testing.

  • Patient was monitored with CTC test.


Test Result

  • 2 CTCs were found during monitoring which indicated recurrence • PET CT showed recurrence. 

  • Recurrence in liver, hence surgery repeated.
