Key clinical point: Adult patients with psoriatic arthritis (PsA) who received biologics, such as interleukin (IL)-12/23, IL-23, and IL-17 inhibitors, or small molecules, such as Janus kinase inhibitors, reported a risk for melanoma and nonmelanoma skin cancer (NMSC).

Major finding: In patients with PsA, the incidence rate of melanoma was 0.09 (95% CI 0.04-0.19) events per 100 patient years (PY) whereas that of NMSC was 0.47 (95% CI 0.28-0.81) events per 100 PY.

Study details: Findings are from a meta-analysis of 19 studies that included 13,739 patients with psoriasis and PsA who were treated with biologics or small molecules tested against an active or placebo comparator.

Disclosures: This study was funded by a research grant from Faculty of Medicine and Health Sciences, Andrzej Frycz Modrzewski Krakow University, Kraków, Poland. P Brzewski declared receiving honoraria or consultation fees from various sources.

Key clinical point: Functional training (FT) and resistance exercise (RE) improved functional capacity, functional status, disease activity, and muscle strength to a comparable extent in patients with psoriatic arthritis (PsA).

Major finding: FT and RE led to similar improvements in functional capacity measured by the Bath Ankylosing Spondylitis Functional Index (P = .919), functional status measured by the Health Assessment Questionnaire for the Spondyloarthropathies (P = 0.932), disease activity measured by the Bath Ankylosing Spondylitis Disease Activity Index (P = .700), and muscle strength in patients with PsA. No adverse event occurred in either group.

Study details: Findings are from a 12-week, single-blind trial that included 41 patients with PsA who were randomly assigned to undergo FT with elastic bands or RE with weight machines.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Study details: This population-based retrospective study included 467,814 patients (age ≥ 20 years) who underwent surgery for LDD, of whom 883 patients had pre-existing PsA and were matched to 8830 patients without PsA.

Key clinical point: Female patients with psoriatic arthritis (PsA) who received tumor necrosis factor inhibitors (TNFi) and interleukin-17 inhibitors (IL-17i) showed lower treatment persistence than male patients with PsA who received the same therapeutic class of drugs.

Major finding: Women demonstrated 20%-40% lower treatment persistence rates than men for TNFi (adjusted hazard ratio [aHR] 1.4; 99% CI 1.3-1.5) and IL-17i (aHR 1.2; 99% CI 1.1-1.3) therapies; however, the treatment persistence between both sexes was comparable for IL12/23i (aHR 1.1; 99% CI 0.9-1.3), IL23i (aHR 1.1; 99% CI 0.7-1.5), and Janus kinase inhibitor (aHR 1.2; 99% CI 0.9-1.6) therapies.

Key clinical point: Although Psoriatic Arthritis Impact of Disease questionnaire-12 items (PsAID-12) scores were higher in patients with psoriatic arthritis (PsA) who did vs did not have a treatment escalation, physicians relied more on their assessment of disease activity while making treatment-related decisions.

Major finding: Higher mean PsAID-12 score correlated with higher odds of treatment escalation in patients with PsA (odds ratio [OR] 1.58; P < .0001), whereas physician’s assessment of disease activity had the most significant impact on likelihood of treatment escalation (OR 2.68; P < .0001). Longer disease duration, treatment with nonbiologics, and a higher swollen joint count also increased the odds for treatment escalation.

Study details: Findings are from a cross-sectional analysis (the ASSIST study) that included 503 patients with PsA (age ≥ 18 years), of whom 160 patients underwent treatment escalation.

Disclosures: This study was funded by Amgen, and the National Institute for Health Research Oxford Biomedical Research Centre. Several authors declared receiving grants, honoraria, consultancy fees, or travel support from or having ties with various sources, including Amgen.

Key clinical point: Neoadjuvant chemotherapy (NAC) that did vs did not contain cisplatin improved survival in patients with operable triple-negative breast cancer (TNBC), especially those with residual cancer burden (RCB) class II/III, a group that is typically associated with worse prognosis.

Major finding: Patients who did vs did not receive cisplatin-based regimens in the overall population reported significantly improved distant disease-free survival (unadjusted hazard ratio [HR] 0.127; P < .001), especially those in the RCB class II/III group (HR 0.192; P = .013).

Study details: Findings are from a retrospective cohort study including 138 previously untreated patients with stage I-III TNBC who received NAC with (n = 52) or without (n = 86) cisplatin.

Key clinical point: Even though disease-free survival (DFS) outcomes were comparable in patients with invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC), the degree of nodal involvement affected prognostic outcomes in both these populations.

Major finding: In patients with ILC vs IDC, DFS was similar in the overall population (P = .743), but it was significantly worse (pN2/pN3; adjusted hazard ratio [aHR] 1.40; P = .033) and better (pN0/pN1; aHR 0.60; P = .005) in patients with extensive and limited nodal involvement, respectively.

Study details: Findings are from a pooled analysis of three phase 3 trials, SUCCESS A, B, and C, which included 7236 intermediate-to-high risk patients with IDC (n = 6284) or ILC (n = 952) and who received adjuvant chemotherapy.

Disclosures: The SUCCESS trials were supported by AstraZeneca, Sanofi-Aventis, and other sources. Two authors declared receiving honoraria from various sources unrelated to this work. Other authors declared no conflicts of interest.

Key clinical point: A molecular subtype-guided treatment based on four triple-negative breast cancer (TNBC) subtypes nearly doubled progression-free survival (PFS) outcomes compared with control therapy with nab-paclitaxel and had a favorable safety profile in patients with metastatic TNBC.

Major finding: Patients who received nab-paclitaxel + subtype-based therapy vs only nab-paclitaxel had significantly longer progression-free survival (median 11.3 months vs 5.8 months; hazard ratio 0.44; P < .0001). Neutropenia (30% vs 23%), anemia (7% vs none), and increased alanine aminotransferase (6% vs 1%) were the most common types of grade 3-4 treatment-related adverse events in the subtype-based group vs control group.

Study details: Findings are from the ongoing phase 2 FUTURE-SUPER trial that included 139 women age 18-70 years with metastatic or recurrent TNBC who were randomly assigned to receive a nab-paclitaxel + subtype-based regimen or only nab-paclitaxel.

Disclosures: This study was supported by Jiangsu Hengrui Pharmaceuticals, the National Key Research and Development Project of China, and other sources. Two authors declared being employees of Jiangsu Hengrui Pharmaceuticals.
