Helping Choose the Right Drugs for Your Cancer Treatment

chemo-scale™ is an analysis of tumor cells to provide drug efficacy and resistance guidance for chemotherapy. With chemo-scale™ analysis, we minimize the risks of therapy failure for the patient – saving money, reducing ‘trial and error’, and most importantly, intensifying the attack of cancer, not the patient.

Why chemo-scale

  • Cancer is a highly heterogenous disease which has unique properties and differs in every patient and hence every patient responds differently to the same chemotherapy regimen.
  • The chemo-scale™ approach directly tests the effect of chemotherapy/anti-cancer drugs on the patient’s tumor cells. It helps to customise the treatment plan according to the sensitivity and resistance pattern of tumor cells.
  • When armed with this information, the physician and the patient can choose the most effective chemotherapy from all available options.
  • chemo-scale™ is the personalisation of chemotherapy by directly studying the effect of chemotherapy drugs on cells taken from a fresh biopsy sample of the tumor or Circulating Tumor Associated Cells (C-TACs) isolated from peripheral blood.

The Advantage of chemo-scale

  • Analysis is carried out for single drug and additional drug combinations on request.
  • It reveals cytotoxic chemotherapy drug effect on patient’s tumor cells.
  • It also reveals the hierarchy of these drug choices in descending order of cell death (%).


Non-invasive, in vitro chemosensitivity on Circulating Tumor-Associated Cells (C-TACs) or tumor cells isolated from a fresh biopsy sample to evaluate Response / Resistance to chemotherapy drugs.


All patients who have been advised chemotherapy at any stage of the disease.


C-TACs from peripheral blood are isolated and tested in vitro to observe comparative cell death when exposed to calibrated doses of cytotoxic drugs.
