Abstract: The lymphatic system (LS) plays a crucial role in fluid balance, transportation of macromolecules,
and immune response. Moreover, LS is a channel for microbial invasion and cancer metastasis.
Particularly, solid tumors, including lung, breast, melanoma, and prostate cancers, are metastasized
across highways of LS. Subsequently, the fabrication of chimeric lymphatic drug delivery systems
(LDDS) is a promising strategy to fight cancer metastasis and control microbial pandemics. In this regard,
LDDS, in terms of PEG-nanoscaled lipid carriers, elicited a revolution during the COVID-19 pandemic
as cargoes for mRNA vaccines. The drug delivered by the lymphatic pathway escapes first-pass
metabolism and enhances the drug's bioavailability. Ample approaches, including synthesis of prodrugs,
trigging of chylomicron biosynthesis, and fabrication of nanocarriers, facilitate lymphatic drug delivery.
Specifically, nanoscales lipid cargoes have the propensity to lymphatic trafficking. Interestingly, TPGSengineered
nanoscale lipid cargoes enhance lymphatic trafficking, increase tissue permeation, and, specifically,
uptake. Moreover, they overcome biological barriers, control biodistribution, and enhance
organelles localization. Most anticancer agents are non-specific, have low bioavailability, and induced
drug resistance. Therefore, TPGS-engineered nanoscale lipid chimeras improve the therapeutic impact
of anticancer agents. This review highlights lymphatic cancer metastasis, nanoscales lipid cargoes as
LDDS, and their influence on lymphatic trafficking, besides the methods of LDD studies.
