ALK-rearranged NSCLC

Subtype of Non-small-cell lung cancer

Clinical / Scientific

EML4-ALK and related fusions drive ALK tyrosine- signalling. ALK inhibitors are established. Resistance is often -domain mutation or bypass.

Core Biological Drivers

ALK fusion

Constitutive ALK .

Key Pathways

MAPK/ERK

Scientific explanation

The RAS–RAF–MEK–ERK cascade transmits mitogenic RTK signals to programmes for proliferation and differentiation.

PI3K/AKT

Scientific explanation

phosphorylates PIP2 to PIP3, recruiting . supports growth, survival, glucose uptake and mTORC1 input. Pathway activation is common via PIK3CA mutation, PTEN loss or -tyrosine- signalling.

JAK/STAT

Scientific explanation

receptors signal through JAKs to STATs. in particular supports survival, invasion and inflammatory gene programmes in many solid and hematologic tumours.

Pathway Convergence

Target → pathway → downstream effect → biological consequence. Shared intersections are mechanistic maps, not protocols.

Growth-factor signalling

Ligand or mutation-driven RTK input feeds PI3K/AKT and mTORC1, supporting anabolic growth. This is a map of signalling, not a treatment protocol.

Metabolic Vulnerabilities

Aerobic supports ATP, biomass and acidification even when oxygen is available. Extent varies by tumour and remains a vulnerability hypothesis rather than a uniform target.

Tumor Microenvironment

Disordered vasculature creates , HIF-1α stabilization, induction and immune-suppressive adenosine/lactate milieus.

Metastasis Module

, protease-mediated invasion, , circulating tumour-cell survival and organ-specific colonization form the metastatic cascade. Pre-metastatic niches and vascular permeability influence tropism.

Resistance Biology

ALK mutations and bypass RTKs.

Cancer Stemness

Wnt, Notch, Hedgehog, ALDH and CD44-associated programmes can mark stem-like fractions with quiescence and therapy tolerance. These markers are not interchangeable across tumour types.

Mechanism-Based Adjunctive Strategies

Compounds appear only where a mechanistic overlap exists for this cancer. Evidence tiers are not equivalent. Nothing here is a treatment recommendation.

Metformin

Clinical / Human EvidenceIn VivoIn VitroMechanistically Plausible

Target / Mechanism

Modest complex I inhibition raises AMP:ATP, activating and restraining hepatic and -linked anabolism. Direct antineoplastic efficacy is not established from that pharmacology alone.

Cancer relevance

activation and restraint provide a metabolic rationale in - and -linked tumours. Human data are mixed and do not establish metformin as cancer therapy.

Metabolic adjunctive research context. Convergence: AMPK, mTOR, Glycolysis.

Mebendazole

In VitroIn VivoMechanistically Plausible

Target / Mechanism

Benzimidazole that binds β-. Mammalian disruption, mitotic arrest and related signalling in cancer models are preclinical and are not an approved anticancer use.

Cancer relevance

disruption can trigger mitotic stress and in cell and animal models. This is not an established oncology use.

Experimental antimitotic / microtubule stress. Convergence: Apoptosis, p53.

This oncology atlas is educational. Pathway maps, adjunctive strategies, and compound listings describe mechanistic relevance. They do not establish clinical efficacy, do not recommend treatment, and are not a substitute for oncology care. Evidence tiers are not equivalent.
