I have asked our breast pathologists to routinely report it on all new samples and if I have a metastatic patient that might be a candidate, I have had pathology go back and stain all their prior samples for it. I’ve now used T’ Dxd in many ultralow patients and it works beautifully.

MALT lymphomas are highly radiosensitive. Curative standard doses are 24 Gy in 12 fractions and 30 Gy in 20 fractions. The latter and slower dose fractionation (30 Gy in 20) is best used specifically in the setting of stage IAE Gastric MALT - a unique site with significant risk of radiation induced ...

This is a question that is being addressed in the salvage setting by NRG GU008. Currently, we have high level evidence that adding abiraterone to ADT is superior to ADT alone for subsets of patients with metastatic disease and the combination with RT is superior to ADT alone plus RT for both clinica...

Antineoplastics drugs, such as pemetrexed, can damage the epithelial cells of the conjunctival mucosa. Inflammation and fibrosis of epithelial cells of the lacrimal duct following systemic chemotherapy may lead to lacrimal outflow obstruction and epiphora. The mechanism of lacrimation caused by trea...

First - isolated tumor cells have no clear impact on prognosis and should NOT be used to alter local or systemic treatment decisions. The TAILORx trial unplanned subgroup suggested a small but real benefit from chemo. However, very few (11%) of premenopausal patients got optimal HRT that included OF...

Chemotherapy drug-specific predictive markers have been impossible to find so far. General chemotherapy sensitivity features have been found, but are not part of any currently clinically used assay. High expression of DNA damage repair genes and high expression of immune-related genes have both been...

There is potentially an interaction between ADT's benefit and the PSA at the time of treatment. This was most well delineated in RTOG 9601 (Dess et al., PMID 32215583), but since then, using modern LHRH agonists, that interaction has been less well established (GETUG-AFU16, SPPORT, and RADICALS-HD)....
