Introduction to Exceptional Response

This exceptional response of pancreatic TB to conservative management makes it imperative that the condition be diagnosed promptly to avoid any futile surgical interventions and associated complications.

We present the first case of breast metastasis (BM) from a UC described in literature who had an exceptional response to second-line therapy with pembrolizumab in association with radiotherapy, showing the efficacy of combining immunotherapy and radiotherapy even in patients with atypical metastatic sites.

Given the rarity of patients with exceptional responses to targeted agents, cooperative efforts to understand the molecular basis for these phenotypes are essential.

Often touted are the exceptional response rates in heavily pretreated patients along with meaningful durability of response and ultimately progressionfree survival that were found in the ZUMA-1 and JULIET studies for axicabtagene ciloleucel (axicel, Yescarta) and tisagenlecleucel (tisa-cel, Kymriah), respectively (Neelapu et al.

One characteristic of the digital age is that attention is not only scarce and increasingly contested but also continuously measured and compared, leading to a heightened value around everything that seems to draw an exceptional response.

• The unexpected response to checkpoint inhibitors could be explained by a very high affinity of the fusion peptide at the junction of BRD4 and NUT to the MHC complex as recently suggested for an exceptional response to an immune checkpoint inhibitor in a fusion bearing low TMB, low PD-L1 expression head and neck carcinoma.

Precision medicine in oncology leverages clinical observations of exceptional response.

While the majority of patients responds to PSMA-RLT, with 10-15% having an exceptional response, approximately 30% of patients is unresponsive to PSMA-RLT.

The mechanism of action for exceptional response was elucidated by in vitro experiments that demonstrated that the fact that tamoxifen can have an agonistic effect in addition to antagonist activity, whereas letrozole results only in estrogen depletion was crucial to the response achieved when letrozole was combined with an MEK inhibitor.

Using a 1 x 1 x 1 design, we rapidly identify tumors with exceptional responses to combination treatments.

It argues, first, that the prominent (counter-)terrorism paradigm – in which terrorism is approached as a ubiquitous and very specific security challenge meriting appropriately exceptional responses – is far more critiqued than we might anticipate.

Purpose: We sought to determine the mechanism of an exceptional response in a patient diagnosed with a SMARCB1/INI1-negative chordoma treated with tazemetostat, an EZH2 inhibitor, and followed by radiotherapy.

Medical record review revealed two patients with HNFS AS received off-label treatment with anti-PD-1 therapy and experienced exceptional responses, highlighting immune checkpoint inhibition as a therapeutic avenue for HNFS AS.

Here we examine the landscape of TMB and PD-L1 expression in breast cancer and present a case of patient with high TMB and PD-L1 negative breast cancer with exceptional response to ICPIs.

The case exhibited an exceptional response to cryoablation followed by pembrolizumab, potentially attributed to mutations in POLE, which lead to an extremely high TMB.

To the Editor: We report an exceptional case of a patient with Tlymphoblastic lymphoma (T-LBL) with a chromosomal translocation resulting in a platelet-derived growth factor receptor beta (PDGFRB) rearrangement who relapsed after receiving standard conventional chemotherapy but subsequently had an exceptional response to single agent tyrosine kinase inhibition.

Three patients with nonmuscle invasive bladder cancer [1 patient with an exceptional response; complete response (CR) for 30 months] who failed intravesical BCG were evaluated using an NYS CLEP approved assay, Immune Report Card, which measures programmed death-ligand 1 expression, CD8+ T-cell infiltration pattern, mutational burden, and gene expression of 51 immune-related transcripts using RNA-Seq.
