Pembrolizumab has shown significantly better efficacy than platinum doublet chemotherapy in patients with programmed cell death ligand 1 (PD-L1) strongly positive (tumor proportion score ≥ 50%)non-small-cell lung cancer (NSCLC). However, the predictors of response to pembrolizumab have not yet been fully elucidated for patients with PD-L1 strongly positiveNSCLC.

We retrospectively analyzed 145 patients who had been treated with pembrolizumab for PD-L1 strongly positive(TPS ≥ 50%) NSCLC without an EGFR (epidermal growth factor receptor) mutation or ALK rearrangement from February 2017 to March 2020. Various clinical characteristics, including Eastern Cooperative Oncology Group performance status, treatment line, PD-L1 expression, C-reactive protein level, neutrophil/lymphocyte ratio, and metastatic sites, and the clinical outcome of pembrolizumab treatment were examined.

Patients with higher PD-L1 expression (≥ 75%; n= 90) had a higher objective response rate (ORR) and longer progression-free survival (PFS) compared with those with lower expression (50%-74%; n= 55; ORR, 51% vs. 33%; P= .0305; median PFS, 13.9 months vs. 5.2 months; P= .0111). In addition, 15 patients with liver metastasis (LM) had a significantly lower ORR and shorter PFS than the 130 patients without LM (ORR, 20% vs. 47%; P= .0468; median PFS, 3.4 months vs. 9.4 months; P= .0018). A multivariate analysis indicated that PD-L1 expression and LM were significant predictors of PFS after pembrolizumab treatment (higher PD-L1 expression hazard ratio, 0.58; 95% confidence interval, 0.38-0.91; P= .0183; presence of LM hazard ratio, 2.05; 95% confidence interval, 1.03-3.82; P= .0420).

PD-L1 expression and LM status were predictors of the efficacy of pembrolizumab in patients with PD-L1 strongly positiveNSCLC.

Brachytherapy is critical for the curative treatment of locally advanced cervical cancer. Although brachytherapy use is declining in the United States (U.S.), novel interstitial or intracavitary applicators and advances in image guidance for applicator placement and treatment planning have allowed for tumor dose escalation while reducing normal tissue toxicity. Recent survey data have suggested insufficient brachytherapy training for radiation oncology trainees in the United States. This study aimed to address these gaps by developing and piloting a simulation-based education (SBE) workshop for MR-guided cervical cancer brachytherapy.

An SBE workshop was developed for graduate medical education (GME) trainees focusing on MR-guided brachytherapy for cervical cancer. Four hands-on stations, simulating aspects of the procedure, were led by a team of gynecological brachytherapy experts. The learners were radiation oncology residents and fellows in a U.S. GME training program. The primary outcome was feasibiliork includes collaboration with other U.S. institutions. Future studies should focus on international adaptation.
The ExteNET trial demonstrated improved invasive disease-free survival (iDFS) with neratinib, an irreversible pan-HER tyrosine kinase inhibitor, versus placebo in patients with human epidermal growth factor receptor 2-positive (HER2
)/hormone receptor-positive (HR
) early-stage breast cancer (eBC).

ExteNET was a multicenter, randomized, double-blind, phase III trial of 2840 patients with HER2
eBC after neoadjuvant/adjuvant trastuzumab-based therapy. Patients were stratified by HR status and randomly assigned 1-year oral neratinib 240 mg/day or placebo. The primary endpoint was iDFS. Descriptive analyses were performed in patients with HR
eBC who initiated treatment≤ 1 year (HR
/≤ 1-year) and > 1 year (HR
/> 1-year) post-trastuzumab.

HR
/≤ 1-year and HR
/> 1-year populations comprised 1334 (neratinib, n= 670; placebo, n= 664) and 297 (neratinib, n= 146; placebo, n= 151) patients, respectively. Absolute iDFS benefits at 5 years were 5.1% in HR
/≤ 1-year (hazard ratio, 0.58; 95% confide improved iDFS in the HER2+/HR+/≤ 1-year population, and a similar trend was observed in patients with residual disease following neoadjuvant treatment. Numerical improvements in central nervous system events and OS were consistent with iDFS benefits and suggest long-term benefit for neratinib in this population.
Aromatase inhibitor (AI)-associated symptoms contribute to early therapy discontinuation. Although guidelines exist for management of these symptoms, little is known about the degree to which physicians address symptoms and adhere to the guidelines for treatment.

In this retrospective chart review, women with hormone receptor-positive breast cancer who were prescribed an AI between October 15, 2012, and September 14, 2017, were randomly selected from the institution's cancer registry. Patient medical records were reviewed to identify the prevalence of symptom documentation and management. Documented symptoms were categorized into musculoskeletal, vasomotor, and urogenital. Symptom treatment guidelines were compiled from the National Comprehensive Cancer Network (NCCN) and the American Cancer Society/American Society of Clinical Oncology (ACS/ASCO). find more Treatments were categorized as either meeting or not meeting the guidelines. Among patients with symptoms recorded, chi-square tests and time-to-event models were used to examine factors associated with treatment and factors associated with guideline-based treatment.

Among 179 women prescribed an AI, 82% had at least one symptom and 46% had multiple symptoms. Of the 147 women with any documented symptom, 97 (66%) received some form of symptom-palliating treatment. Seventy-seven patients (52%) received guideline-based treatments or guideline-based treatments in combination with non-guideline-based treatments. There were no differences in receipt of treatment overall (ie, guideline based or non-guideline based) for either vasomotor or musculoskeletal symptoms by age, race, or stage.

Although 82% of patients had symptoms documented in their medical records, just over half of those patients received guideline-based treatment.
