Key clinical point: Postoperative adjuvant transcatheter arterial chemoembolization (TACE) offers a favorable prognosis in hepatocellular carcinoma (HCC) with micronecrosis but limited efficacy against HCC without micronecrosis.

Major finding: Adjuvant TACE significantly improved the overall survival (OS; P  =  .004) and disease-free survival (DFS; P  =  .034) of patients with micronecrosis but led to a nonsignificant difference in the OS (P  =  .430) and DFS (P  =  .131) of patients without micronecrosis.

Study details: This retrospective study propensity score-matched patients who underwent curative liver resection for HCC with (n = 328) or without (n = 438) micronecrosis, with each group comprising patients who did or did not (1:1) receive adjuvant TACE after liver resection.

Disclosures: This study was supported by the National Key Research & Development Program of China and others. No information on conflicts of interest was available.

Key clinical point: Transarterial chemoembolization (TACE) via transradial access (TRA) leads to improved patient satisfaction along with similar procedural variables and safety compared with TACE via transfemoral access (TFA) in patients with hepatocellular carcinoma (HCC).

Major finding: In the TACE-TRA vs TACE-TFA group a significantly higher proportion of patients preferred the current access for their next procedure (90.8% vs 24.6%; P < .001), although between-group procedural variables (such as procedure time and length of hospital stay; all P > .05) and the incidence and severity of adverse events (all P > .05) were similar.

Study details: This single-center prospective randomized controlled trial included 130 patients with HCC who underwent TACE for the first time either via TRA (n = 65) or TFA (n = 65).

Key clinical point: Lenvatinib may continue to benefit patients with unresectable hepatocellular carcinoma (uHCC) despite liver function deterioration to Child-Pugh class B (CP-B) after therapy initiation.

Major finding: CP-B vs CP-A patients receiving lenvatinib had a median progression-free survival (PFS) and overall survival (OS) of 3.7 months (95% CI 1.8-7.4) vs 6.5 months (95% CI 5.6-7.4) and 6.8 months (95% CI 2.6-10.3) vs 13.3 months (95% CI 11.6-16.1), respectively. CP-B patients receiving sorafenib had a median PFS and OS of only 0.5 months (95% CI 0.1-3.6) and 4.5 months (95% CI 2.9-6.1, respectively. Lenvatinib showed no new safety signals in CP-B patients.

Study details: This post hoc analysis included patients with uHCC from the REFLECT trial whose liver function deteriorated to CP-B or remained CP-A within 8 weeks of randomization to lenvatinib (CP-B: n = 60; CP-A: n = 413) or sorafenib (CP-B: n = 47; CP-A: n = 427).

Key clinical point: Letrozole-associated controlled ovarian hyperstimulation (LetCOH) was as effective as conventional controlled ovarian hyperstimulation (cCOH) for fertility preservation (FP) and minimized the risk for supraphysiologic estrogen exposure; however, more patients in the LetCOH group relapsed.

Major finding: In the LetCOH vs cCOH group, estradiol peak at the ovulation trigger was lower, but oocyte maturation rates were significantly higher (P < .001), and the final number of mature oocytes collected was comparable (P   =   .281). Disease recurrence occurred in 17% and 7.2% of patients in the LetCOH and cCOH groups, respectively.

Study details: Findings are from a retrospective observational study including 97 patients with nonmetastatic breast cancer (BC) who were ≤ 40 years old and had undergone FP with LetCOH (n = 41) or cCOH (n = 56) before receiving chemotherapy.

Key clinical point: Women who were diagnosed with breast cancer (BC) at a young age and underwent fertility preservation (FP) did not experience any increased risk for disease-specific mortality or relapse.

Major finding: Compared with women who did not undergo FP, disease-specific mortality was similar in women who underwent hormonal FP (adjusted hazard ratio [aHR] 0.59; 95% CI 0.32-1.09) and nonhormonal FP (aHR 0.51; 95% CI 0.20-1.29). Hormonal (aHR 0.81; 95% CI 0.49-1.37) and nonhormonal (aHR 0.75; 95% CI 0.35-1.62) FP were associated with similar relapse or death rates in a subcohort of 723 women with complete relapse information.

Study details: Findings are from an analysis of a population-based nationwide cohort study including 1275 women of reproductive age (18-44 years old) who were diagnosed with BC, of which 425 women received hormonal (n = 367) or nonhormonal (n = 58) FP treatment.

Key clinical point: In estrogen receptor-positive/human epidermal growth factor receptor-positive (ER+/HER2+) breast cancer (BC), HER2-enriched (HER2-E) tumors were more likely to respond poorly to aromatase inhibitor (AI) therapy and pose an increased risk for disease recurrence.

Major finding: AI-treated HER2-E tumors were associated with poorer Ki67 response and higher Ki67 expression level at 2-weeks timepoint compared with luminal A and B tumors (odds ratio 1.52-12.31; false discovery rate < 0.0001). HER2-E subtype was an independent predictor of shorter time to recurrence (hazard ratio 2.55; P   =   .022).

Study details: Findings are from the phase 3 POETIC trial including 342 patients with early ER+/HER2+ BC who were assigned to 2 weeks of perisurgical AI (n = 237) or no AI (n = 105).

Disclosures: This study was funded by Cancer Research UK. Some authors declared holding or filing patents or receiving grants, nonfinancial support, consulting fees, honoraria, or research funding from several sources.
