About Antineoplastics

What it is

Antineoplastic agents are medicines that treat cancer: classic chemotherapy (alkylating agents, antimetabolites, anthracyclines, taxanes, platinum agents and others), targeted medicines that block specific growth signals, hormone therapies and immunotherapies. This page collects studies that looked at cancer medicines as a broad group.

How genes come into it

Studies of cancer medicines as a broad group looked at TP53, ABCB1, ABCG2, MTHFR and DPYD, mostly in people treated with several medicines at once. The strongest inherited-gene findings belong to individual medicines and have their own guidelines: DPYD for fluorouracil and capecitabine, TPMT and NUDT15 for the thiopurines, and UGT1A1 for irinotecan. Many targeted medicines depend instead on changes in the tumour, which are not inherited.

Rated evidence (5 rated variants)

PharmGKB weighs all studies of a variant and rates how strong the evidence is, from 1A (strongest) to 4.

TP53 rs1042522: Level 3. Toxicity: Drug Toxicity. 5.

DPYD rs1760217: Level 3. Efficacy: Pancreatic Neoplasms. 1.

SERPINA3 rs17091162: Level 3. Efficacy: Pancreatic Neoplasms. 1.

RBFOX1 rs6500843: Level 3. Efficacy: Breast Neoplasms. 1.

Response (5 findings)

Studies of how well it worked in people carrying a variant.

ABCG2 rs2231142: Genotype GG is associated with decreased response to antineoplastic agents in people with Colorectal Neoplasms as compared to genotypes GT + TT.

ABCG2 rs2231137: Genotype CC is not associated with response to antineoplastic agents in people with Colorectal Neoplasms as compared to genotypes CT + TT.

CYP2D6 CYP2D6*1, CYP2D6*4: CYP2D6 *4 is not associated with response to antineoplastic agents and tamoxifen in women with Breast Neoplasms as compared to CYP2D6 *1.

MTHFR rs1801131: Genotype TT is not associated with response to antineoplastic agents in people with Colorectal Neoplasms as compared to genotypes GG + GT.

Study findings and evidence levels: PharmGKB (CC BY-SA 4.0). Guidelines: CPIC and DPWG, as bundled in PharmCAT. Most studies were done mainly in people of European ancestry.
