Sentinel Solid — Monitoring solid tumours on treatment.

SENTINEL · MONITORING SOLID TUMOURS ON TREATMENT

Sentinel Solid is continuous monitoring for solid tumours during active treatment for advanced disease. From repeat blood draws, it tracks ctDNA to show whether therapy is working and to catch molecular progression or resistance early — often before imaging reveals the cancer moving.

What It Watches For

2 · What it watches for

Sentinel Solid tracks the signals that matter most during active treatment.

Response

Falling ctDNA as an early sign the current therapy is working.

Molecular progression

A rising trend that can precede radiographic progression.

Resistance mutations

New changes that let the cancer escape the current drug, so a switch can be planned in time.

Red flag

A rising ctDNA trend or new resistance mutation on a scheduled draw.

Clinical briefing

KPCIRC reviews it in the context of your treatment.

Counter-attack

Evidence-based next options are surfaced — switch, combination, or trial.

Why It Needs a Baseline

4 · Why it needs a baseline

Tracking works best against a molecular fingerprint.

A baseline profile (for example Signature STb O, 118 genes) establishes what to follow, so later draws can be compared meaningfully and resistance spotted early.

5 · Honest limits. Sentinel Solid can provide valuable lead time, but sensitivity depends on ctDNA shedding, and monitoring supports — it does not replace — scans and specialist judgement. Every treatment change is decided by KPCIRC clinicians with you.

Terminology

TERMINOLOGY ON THIS PAGE

The words you will see, in plain language

Term / What it means
ctDNACirculating tumour DNA — tumour DNA fragments a blood test can read over time.
Resistance mutationA new change that lets a cancer escape a treatment that was working.
Molecular progressionA rise in ctDNA signalling the cancer is advancing — often before a scan shows it.
VAFVariant allele frequency — how much of a mutation is present; tracked up or down over time.
Serial monitoringRepeat testing at intervals to watch trend, not just a single snapshot.
Important information about this test

Sentinel Solid is a genomic (DNA-based) test offered for use by qualified healthcare professionals. It is intended to support — not replace — clinical judgement, and must be interpreted alongside your full clinical history, other investigations, and applicable guidelines.

  • • A result is not a diagnosis and does not by itself decide treatment.
  • • A "not detected" or normal result does not rule out cancer or a genetic change.
  • • Not all cancers release enough DNA into blood to be detected.
  • • The test does not guarantee access to any medicine, its regulatory approval, insurance cover, or that a therapy will work.
  • • Sample-collection kits are for use by qualified phlebotomists only — not for self-testing or self-sampling.
  • • Confirmatory testing may be required.

Regulatory status (India). OnKommon's registration of its genomic tests as in-vitro diagnostic (IVD) medical devices with the Central Drugs Standard Control Organisation (CDSCO) is in progress (IVD class pending). Sequencing and variant calling are performed by an accredited laboratory partner (College of American Pathologists — CAP-accredited; ISO 15189) following international guidelines (ACMG/AMP/ASCO/CAP) using a CE-IVD certified variant database. The OnKommon interpretation engine is provided for research and decision-support use. Marketing follows the Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954 and applicable Indian advertising standards.
