Neoadjuvant treatment with nivolumab combined with chemotherapy led to a significant improvement in pathologic complete response compared with chemotherapy alone in patients with resectable non–small cell lung cancer.

Justin Moyers, MD, discusses real-world data and sociodemographic factors from an early analysis of the National Cancer Database associated with the treatment of adjuvant immunotherapy in stage III melanoma.

Patients with breast cancer who harbor multiple PIK3A-mutant tumors achieved a higher clinical benefit from PI3Kα inhibition compared with single mutant tumors according to response analysis data from the SANDPIPER trial.

The neoadjuvant combination of nivolumab and ipilimumab continues to demonstrate a benefit in RFS compared with the combination given in the adjuvant setting in patients with stage III macroscopic melanoma.

Sheila Figel, PhD, a neuro-oncologic scientist with Roswell Park Comprehensive Cancer Center, discusses preclinical research with canonical and noncanonical that are displayed on the surface of cancer cells.

The combination of nivolumab and ipilimumab provided similar clinical benefit to that of chemotherapy when given as a frontline treatment for patients with advanced non–small cell lung cancer who had stable and treated brain metastases at baseline.

Tiragolumab in combination with atezolizumab (Tecentriq) demonstrated early clinical activity and was found to be well tolerated in patients with advanced solid tumors, including those with metastatic non–small cell lung cancer who were PD-L1 positive and had not received prior checkpoint inhibition.

Leora Horn, MD, MSc, discusses data from an updated analysis of the phase 3 IMpower133 trial, which examined the first-line combination of atezolizumab (Tecentriq), carboplatin, and etoposide in small cell lung cancer.

The HER2-selective TKI tucatinib (Tukysa) demonstrated potent antitumor activity alone and in combination with ado-trastuzumab emtansine (T-DM1; Kadcyla) in HER2-overexpressing breast cancer cell lines and xenograft models.

Circulating tumor DNA clearance of EGFR mutation may be predictive of prolonged progression-free survival for patients with EGFR-mutant, MET-amplified non–small cell lung cancer with detectable ctDNA at baseline.

Timothy Cragin Wang, MD, discusses the lack of response to checkpoint inhibitors in colorectal cancer.

The FDA is presently spearheading several initiatives in light of COVID-19 aimed at refining the role of RWD in cancer care to guide clinical trial development, procure answers to pressing clinical questions, and support regulatory decisions for in vitro diagnostics.

In urothelial carcinoma models, enfortumab vedotin-ejfv appeared to promote multiple mechanisms of action such as bystander cell killing, supporting the use of the agent either alone or in combination with pembrolizumab.

In preclinical models, the novel irreversible BTK inhibitor TG-1701 demonstrated similar activity to ibrutinib in mantle cell lymphoma cell lines and showed additive benefit when combined with ublituximab and umbralisib in non-Hodgkin lymphoma model.

Neal D. Shore, MD, FACS, discusses immunotherapy targeting prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) in biochemically recurrent prostate cancer.

The combination of atezolizumab plus carboplatin/etoposide continued to demonstrate an improvement in overall survival versus chemotherapy alone as a frontline treatment for patients with extensive-stage small cell lung cancer.

Tucatinib was found to be a potent inhibitor of HER2-mutant signaling in vitro.

Robert Rintoul, BSc, MB ChB, PhD, FRCP, discusses the importance of minimal residual disease assessment in patients with non–small cell lung cancer.

Three main survivin isoforms demonstrated the ability to translocate to the surface of plasma membrane in multiple cell types, suggesting a targetable role as a molecular biomarker.

Significant differences were seen between Hispanic and non-Hispanic white patients with hematological malignancies in Texas in terms of the age of diagnosis and long-term survival outcomes.

The use of adjuvant immunotherapy in patients with resected stage IIIC melanoma resulted in improved survival benefit, according to real-world data from an early analysis of the National Cancer Database.

Patients 18 to 39 years of age with early-onset cancer had a significantly high risk of harboring germline mutations, suggesting that this population should undergo germline genetic testing, irrespective of tumor type.

The addition of the individualized neoantigen specific immunotherapy RO7198457 to atezolizumab induced neoantigen-specific T-cell responses, and was found to be well tolerated in patients with advanced solid malignancies.

Findings from an observational study of more than 10,000 women with ovarian cancer showed that lipophilic statins were associated with a 43% overall reduction in epithelial ovarian cancer mortality, with declines seen across subtypes.

COM701, a novel, first-in-class immune checkpoint inhibitor, was found to demonstrate encouraging preliminary antitumor activity and good tolerability when used as either a monotherapy and in combination with nivolumab in a number of heavily pretreated patients with advanced or metastatic solid tumors, according to data from a phase 1 trial.

Alain Algazi, MD, discusses the benefit of continuous dosing with dabrafenib (Tafinlar) and trametinib (Mekinist) in patients with BRAF mutation–positive advanced melanoma.

The combination of the RAF-MEK inhibitor VS-6766 (CH5126766) and the FAK inhibitor defactinib (VS-6063) elicited early signals of clinical activity in a group of patients with KRAS-mutant advanced cancers.

Circulating tumor DNA may be a biomarker for the detection of postsurgical minimal residual disease and for determining the clonality of relapsing disease.
