This a great question and a common clinical scenario that we are all confronted with. Stereotactic body radiation therapy (SBRT) is being increasingly used for oligometastatic progression of EGFR mutant NSCLC. The theoretical risk of combining EGFR inhibitors and radiation therapy would be an enhanc...

I personally think fewer fractions are safer, such as 30 Gy x 1 instead of 10 Gy x 5, for patients with advanced COPD or ILD. Why? It's because each time a burst of ionization events is delivered to pulmonary tissues, a wound is created that recruits an inflammatory response, which can exacerbate th...

I think that the data regarding Sac-TMT vs. frontline platinum chemotherapy was the most impactful data. With all of the caveats of a China-only study, this is the first time that we have seen an ADC demonstrate a survival advantage in this setting. The other two presentations are less novel, but t...

I would not treat this the way I would a typical triple-negative breast cancer, since the risk of distant recurrence from occult metastatic disease is low. Assuming she had breast-conserving surgery, radiation, favoring partial breast, is reasonable. In terms of systemic therapy, if the cancer in th...

An assessment of three domains is going to help the patient and physicians in this case: Patient related factors: A medical emergency that lasts three months implies a lot-- so what is the performance status of the patient now and what is the prognosis; because an ECOG 3-4+ patient with new onset mu...

My default form of ADT remains a GnRH agonist or antagonist but estradiol transdermal patches are clearly effective and safe as an alternative option for men who either 1) have significant loss of bone density/osteoporosis, 2) have significant hot flashes with traditional ADT and wish to try an alte...

NRG GI011 was recently activated across the NCTN and will test ablative radiotherapy in this setting. This is a pragmatic and potentially practice-changing trial. Consider activating it at your center. Here is a nice summary from the PI @Dr. First Lasthttps://www.youtube.com/watch?v=MNsS7pHqZIk.

The BED to the heart isn't actually higher in this setting.Dr. @Dr. First Last explained this below, but I'll just explain it another way. Imagine that you place the block edge so that it is touching the heart (i.e., the heart is completely covered by the MLCs, and there is no margin between the MLC...

I would not offer RT if planned for mastectomy in 6 months, as based on phenotype, median time for recurrence is 2 to 5 years, and RT can also negatively impact the cosmetic outcome with reconstruction.
