Short- and long-term effects of clinical pathway on the quality of surgical non-small cell lung cancer care in China: an interrupted time series study

Evidence Review for the American College of Surgeons Quality Verification Part III: Standardization, Protocols, and Achieving Better Outcomes for Patient Care

BACKGROUND

After decades of experience supporting surgical quality and safety by the American College of Surgeons (ACS), the ACS Quality Verification Program (ACS QVP) was developed to help hospitals improve surgical quality and safety. This review is the final installment of a 3-part review aimed to synthesize evidence supporting the main principles of the ACS QVP.

STUDY DESIGN

Evidence was systematically reviewed for 3 principles: standardized team-based care across 5 phases of surgical care, disease-based management, and external regulatory review. MEDLINE was searched for articles published from inception to January 2019 and 2 reviewers independently screened studies for inclusion in a hierarchical manner, extracted data, and summarized results in a narrative fashion. A total of 5,237 studies across these 3 topics were identified. Studies were included if they evaluated the relationship between the standard of interest and patient-level or organization measures within the last 20 years.

RESULTS

After applying inclusion criteria, a total of 150 studies in systematic reviews and primary studies were included for assessment. Despite institutional variation in standardized clinical pathways, evidence demonstrated improved outcomes such as reduced length of stay, costs, and complications. Evidence for multidisciplinary disease-based care protocols was mixed, though trended toward improving patient outcomes such as reduced length of stay and readmissions. Similarly, the evidence for accreditation and adherence to external process measures was also mixed, though several studies demonstrated the benefit of accreditation programs on patient outcomes.

CONCLUSIONS

The identified literature supports the importance of standardized multidisciplinary and disease-based processes and external regulatory systems to improve quality of care.

International standards of care in thoracic oncology: A narrative review of clinical quality indicators

Unwarranted variations in lung cancer care are widely described. Clinical Quality Indicators (CQIs) enable the systematic identification and alleviation of variations in care and other evidence-practice gaps. The aim of this review was to describe and evaluate lung cancer CQIs utilised internationally, in order to provide a substrate for the development of Australasian lung cancer CQIs and future quality improvement initiatives. A literature search was performed to identify relevant publications; references were excluded if they did not explicitly define original lung cancer-specific quality indicators, or were review or opinion articles. Ultimately, 48 publications containing 661 individual CQIs were evaluated. Although almost all references were published in the last decade, CQIs did not always reflect contemporary standards of care. For example, there were just sixteen CQIs regarding biomarker profiling, eleven CQIs regarding multidisciplinary team review, and three clinical trial enrolment CQIs. Of 307 lung cancer treatment CQIs, almost half (137) pertain to surgical resection; a treatment option available to a minority of lung cancer patients. Consumer engagement during indicator development was uncommon. In conclusion, whilst CQIs are widely measured and reported, they are not always consistent with evidence-based practice, nor do they reliably support the holistic evaluation of the lung cancer care continuum. Moving forward, Australia and New Zealand must adopt a unified, evidence-based and patient-centred approach to drive meaningful improvements in practice.

Salvianolic acid F suppresses KRAS-dependent lung cancer cell growth through the PI3K/AKT signaling pathway

BACKGROUND

KRAS mutation is a common driver of NSCLC, and there is a high proportion of lung cancer patients with KRAS G12C and G12D mutation. KRAS was previously considered an "undruggable" target, but the first KRAS G12C mutation-targeted drug AMG510, entered the market in 2021. However, treatments for G12D mutant tumors remain to be discovered. Salvianolic acid F (SalF), a monomer derived from the traditional Chinese medicine Salvia miltiorrhiza (SM), and KRAS had high binding affinity, especially for KRAS G12D. There is an urgent need to investigate effective and safe novel targeted therapies against KRAS G12D-driven NSCLC.

METHODS

To evaluate the anticancer effect of SalF, we used KRAS-overexpressing lung cancer cells in vitro, a subcutaneous transplant tumor model, and KRAS G12D mice model in vivo. Then, the binding effect of SalF and KRAS was investigated using molecular docking, proteolytic assays and protein thermal shift assays. More critically, the PI3K/AKT signaling pathway in the lung was investigated utilizing RT-qPCR and Western Blotting.

RESULTS

This is the first study to evaluate the anticancer effect of SalF on KRAS-overexpressing lung cancer cells or KRAS G12D lung tumors in vivo. We demonstrated that SalF inhibits OE-KRAS A549 cell migration, proliferation and promotes apoptosis in vitro. In addition, we used a subcutaneous transplant tumor model to show that SalF suppresses the growth of lung cancer cells in vivo. Interestingly, our group found that SalF was strongly bound to G12D and could decrease the stability and promoted the degradation of the KRAS G12D mutant through molecular docking, proteolytic assays and protein thermal shift assays. Further research demonstrated that in the KrasG12D mice model, after SalF treatment, the number and size of mouse lung tumors were significantly reduced. More importantly, SalF can promote apoptosis by inhibiting downstream PI3K/AKT signaling pathway activation.

CONCLUSION

SalF activated apoptosis signaling pathways, suppressed anti-apoptotic genes, and inhibited lung cancer cell growth. These datas suggested that SalF could effectively inhibit the growth of lung tumors with KRAS G12D mutation. SalF may be a novel inhibitor against KRAS G12D, providing a strong theoretical basis for the clinical treatment of lung cancer with KRAS mutations.

Oncology Medical Home: ASCO and COA Standards

PURPOSE

To provide Standards on the basis of evidence and expert consensus for a pilot of the Oncology Medical Home (OMH) certification program. The OMH model is a system of care delivery that features coordinated, efficient, accessible, and evidence-based care and includes a process for measurement of outcomes to facilitate continuous quality improvement. The OMH pilot is intended to inform further refinement of Standards for OMH model implementation.

METHODS

An Expert Panel was formed, and a systematic review of the literature on the topics of OMH, clinical pathways, and survivorship care plans was performed using PubMed and Google Scholar. Using this evidence base and an informal consensus process, the Expert Panel developed a set of OMH Standards. Public comments were solicited and considered in preparation of the final manuscript.

RESULTS

Three comparative peer-reviewed studies of OMH met the inclusion criteria. In addition, the results from 16 studies of clinical pathways and one systematic review of survivorship care plans informed the evidence review. Limitations of the evidence base included the small number of studies of OMH and lack of longer-term outcomes data. More data were available to inform the specific Standards for pathways and survivorship care; however, outcomes were mixed for the latter intervention. The Expert Panel concluded that in the future, practices should be encouraged to publish the results of OMH interventions in peer-reviewed journals to improve the evidence base.

STANDARDS

Standards are provided for OMH in the areas of patient engagement, availability and access to care, evidence-based medicine, equitable and comprehensive team-based care, quality improvement, goals of care, palliative and end-of-life care discussions, and chemotherapy safety. Additional information, including a Standards implementation manual, is available at www.asco.org/standards.

Impact of visceral pleural invasion on the association of extent of lymphadenectomy and survival in stage I non-small cell lung cancer

Visceral pleural invasion (VPI) has been identified as an adverse prognostic factor for non‐small cell lung cancer (NSCLC). Accurate nodal staging for NSCLC correlates with improved survival, but it is unclear whether tumors with VPI require a more extensive lymph nodes (LNs) dissection to optimize survival. We aimed to evaluate the impact of VPI status on the optimal extent of LNs dissection in stage I NSCLC, using the Surveillance, Epidemiology, and End Results (SEER) database. We identified 9297 surgically treated T1‐2aN0M0 NSCLC patients with at least one examined LNs. Propensity score matching was conducted to balance the baseline clinicopathologic characteristics between the VPI group and non‐VPI group. Log‐rank tests along with Cox proportional hazards regression methods were performed to evaluate the impact of extent of LNs dissection on survival. VPI was correlated with a significant worse survival, but there was no significant difference in survival rate between PL1 and PL2. Patients who underwent sublobectomy had slightly decreased survival than those who underwent lobectomy. Pathologic LNs examination was significantly correlated with survival. Examination of 7‐8 LNs and 14‐16 LNs conferred the lowest hazard ratio for T1‐sized/non‐VPI tumors (stage IA) and T1‐sized/VPI tumors (stage IB), respectively. The optimal extent of LNs dissection varied by VPI status, with T1‐sized/VPI tumors (stage IB) requiring a more extensive LNs dissection than T1‐sized/non‐VPI tumors (stage IA). These results might provide guidelines for surgical procedure in early stage NSCLC.
