The treatment landscape for advanced hepatocellular carcinoma (aHCC) is rapidly expanding beyond tyrosine kinase inhibitors (TKIs) in the first-line (1L) setting, with multiple TKIs and immune-checkpoint inhibitors (ICIs) now being evaluated in combination. Real-world evidence describing current treatment patterns and reasons for 1L and 2L treatment selection in aHCC is sparse.

A retrospective cohort study with a cross-sectional survey element was conducted using Cardinal Health's Oncology Provider Extended Network. U.S. medical oncologists identified adult aHCC patients initiating 1L systemic therapy between January 1, 2017 and July 31, 2019 and abstracted data from patient medical records. SZL P1-41 ic50 Data included provider characteristics, patient demographics and clinical characteristics, treatment regimens, and physician rationale for treatment regimen choice.

A total of 44 medical oncologists provided data on 284 aHCC patients. The median age at 1L initiation was 61.5 years, and the majority were male (78%) and white (66%). Nearly half (47%) initiated 1L treatment in 2019, 34% were ECOG performance status 2+, and 63% were Child-Pugh Class B/C. Among the 284 aHCC patients, TKIs were used by 94% of patients in the 1L setting, comprised predominantly of sorafenib (54%) and lenvatinib (38%). ICIs were most common among the 90 patients (66%) who received 2L treatment.

In the community-oncology practice setting, nearly all aHCC patients received sorafenib or lenvatinib in the 1L setting, while the majority of patients received an ICI in the 2L setting. With recent ICI approvals in aHCC, this marks the beginning of an increased use of ICIs in the 1L setting.

In high-income settings, delays from breast cancer (BC) diagnosis to initial treatment worsen overall survival (OS). We examined how time to BC treatment initiation (TTI) impacts OS in South Africa (SA).

We evaluated women enrolled in the South African BC and HIV Outcomes study between July 1, 2015 and June 30, 2019, selecting women with stages I-III BC who received surgery and chemotherapy. We constructed a linear regression model estimating the impact of sociodemographic and clinical factors on TTI and separate multivariable Cox proportional hazard models by first treatment (surgery and neoadjuvant chemotherapy (NAC)) assessing the effect of TTI (in 30-day increments) on OS.

Of 1260 women, 45.6% had upfront surgery, 54.4% had NAC, and 19.5% initiated treatment >90 days after BC diagnosis. Compared to the surgery group, more women in the NAC group had stage III BC (34.8% vs 81.5%). Living further away from a hospital and having hormone receptor positive (vs negative) BC was associated with longer TTI (8 additional days per 100 km, P = .003 and 8 additional days, P = .01, respectively), while Ki67 proliferation index >20 and upfront surgery (vs NAC) was associated with shorter TTI (12 and 9 days earlier; P = .0001 and.007, respectively). Treatment initiation also differed among treating hospitals (P < .0001). Additional 30-day treatment delays were associated with worse survival in the surgery group (HR 1.11 [95%CI 1.003-1.22]), but not in the NAC group.

Delays in BC treatment initiation are common in SA public hospitals and are associated with worse survival among women treated with upfront surgery.

Homologous recombination deficiency (HRD) is a phenotype that is characterized by the inability of a cell to effectively repair DNA double-strand breaks using the homologous recombination repair (HRR) pathway. Loss-of-function genes involved in this pathway can sensitize tumors to poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitors and platinum-based chemotherapy, which target the destruction of cancer cells by working in concert with HRD through synthetic lethality. However, to identify patients with these tumors, it is vital to understand how to best measure homologous repair (HR) status and to characterize the level of alignment in these measurements across different diagnostic platforms. A key current challenge is that there is no standardized method to define, measure, and report HR status using diagnostics in the clinical setting.

Friends of Cancer Research convened a consortium of project partners from key healthcare sectors to address concerns about the lack of consistency in the way HRD is defined and methods for measuring HR status.

This publication provides findings from the group's discussions that identified opportunities to align the definition of HRD and the parameters that contribute to the determination of HR status. The consortium proposed recommendations and best practices to benefit the broader cancer community.

Overall, this publication provides additional perspectives for scientist, physician, laboratory, and patient communities to contextualize the definition of HRD and various platforms that are used to measure HRD in tumors.

Changes in autumnal phenology (i.e., leaf senescence) and associated leaf nutrient resorption may profoundly impact plant fitness and productivity. However, we know little about how and to what extent nutrient addition affects leaf senescence in tree species, or how changes in senescence may influence resorption. We thus investigated the impacts of N and P addition on leaf senescence and leaf N resorption in 2-year-old larch (Larix principisrupprechtii) seedlings in northern China. Results showed that nutrient addition (i.e., N, P or N + P addition) significantly delayed autumnal leaf senescence, and decreased leaf N resorption efficiency (NRE) and proficiency (NRP), particularly in the N and N + P treatments. Improved leaf N concentrations were correlated with delayed leaf senescence, as indicated by the positive relationship between mature leaf N concentor plant nutrient conservation strategy and nutrient cycling.
Low areal bone mineral density (BMD), increased fracture risk, and altered bone remodelling have been described among stone formers (SF), but the magnitude of these findings differs by age, sex, menopausal status, and urinary calcium (uCa). This study aimed to investigate volumetric (v) BMD, bone microarchitecture and biomechanical properties by high-resolution peripheral quantitative computed tomography (HR-pQCT) and finite element analysis (FEA) in young SF, irrespective of calciuria, further distinguishing trabecular from cortical compartments.

HR-pQCT/FEA was performed at distal tibia (DT) and radius (DR) in 106 SF (57 males/49 premenopausal females; median age, 37 years) and compared with 106 non-SF (NSF) retrieved from an existing database, matched for age, sex, and body mass index (BMI). Biochemical/hormonal serum and urinary parameters were obtained from SF.

SF exhibited significantly lower trabecular number (Tb.N), higher trabecular separation (Tb.Sp) than NSF at both anatomical sites and lower cortical porosity in DR. In a subgroup analysis separated by sex, female SF presented significantly lower Tb.vBMD, relative bone volume fraction (BV/TV) and Tb.N, and higher Tb.Sp than NSF at both sites, while male SF showed significantly lower stiffness and failure load. A multivariate analysis showed Tb.N to be independently associated with sex and BMI at both sites and with uCa at DR.

The present findings suggest that bone disease represents an early event among SF, associated at least in part with calcium excretion, and mainly characterized by trabecular bone microarchitecture impairment, especially among women, but with reduced bone strength parameters in men.

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) are standard of care for patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC) with common mutations (Del19 or L858R); however, 7%-23% of NSCLC tumors harbor uncommon EGFR mutations. These mutations are highly heterogeneous, and developments in detection techniques are helping to identify mutations with little or no clinical data.

In this retrospective, global, multi-center study (NCT04179890), existing health records were identified for consecutive EGFR TKI-naïve patients with uncommon EGFR mutations (T790M, ex20ins, major uncommon [G719X, L861Q, or S768I], or "other" mutations; compound mutations) treated with erlotinib, gefitinib, afatinib, or osimertinib in first or second line. Endpoints included time-to-treatment failure (TTF), objective response rate (ORR), and overall survival (OS).

Overall, 246 patients (median age 69.5 years; Asian 84%) were included from 9 countries. Most patients (92%) received an EGFR TKI as first-line therapy; 54%, 43% and 3% received afatinib, first-generation TKIs, and osimertinib, respectively. Median TTF and OS with EGFR TKIs were 9.9 and 24.4 months; ORR was 43%. In patients treated with first-line chemotherapy (n = 20), median TTF and ORR were 6.6 months and 41%. Outcomes were most favorable in patients with major uncommon or compound mutations. Overall, TTF was 11.3 months with afatinib and 8.8 months with first-generation EGFR TKIs across mutation categories. In most mutation categories, median OS was >2 years.

In a real-world setting, EGFR TKIs were the preferred treatment option in patients with uncommon EGFR mutations; strongest outcomes were seen in patients with major uncommon and compound mutations.

After the first identification of ASCs in humans in 2001, the knowledge of their cell biology and cell characteristics have advanced, and respective therapeutic options were determined. Nowadays, ASC-based therapies are on the verge of translation into clinical practice. However, conflicting evidence emerged in recent years about the safety profile of ASC applications as they may induce tumor progression and invasion. Numerous in-vitro and in-vivo studies demonstrate a potential pro-oncogenic effect of ASCs on various cancer entities. This raises questions about the safety profile of ASCs and their broad handling and administration. However, these findings spark controversy as in clinical studies ASC application did not elevate tumor incidence rates, and other experimental studies reported an inhibitory effect of ASCs on different cancer cell types.
