Preoperative Chemoradiotherapy vs Chemotherapy for Adenocarcinoma of the Esophagogastric Junction: A Network Meta-Analysis.

Importance: The prognosis of patients with adenocarcinoma of the esophagus and esophagogastric junction (AEG) is poor. From current evidence, it remains unclear to what extent preoperative chemoradiotherapy (CRT) or preoperative and/or perioperative chemotherapy achieve better outcomes than surgery alone. Objective: To assess the association of preoperative CRT and preoperative and/or perioperative chemotherapy in patients with AEG with overall survival and other outcomes. Data Sources: Literature search in PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, and International Clinical Trials Registry Platform was performed from inception to April 21, 2023. Study Selection: Two blinded reviewers screened for randomized clinical trials comparing preoperative CRT plus surgery with preoperative and/or perioperative chemotherapy plus surgery, 1 intervention with surgery alone, or all 3 treatments. Only data from participants with AEG were included from trials that encompassed mixed histology or gastric cancer. Among 2768 initially identified studies, 17 (0.6%) met the selection criteria. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed for extracting data and assessing data quality by 2 independent extractors. A bayesian network meta-analysis was conducted using the 2-stage approach. Main Outcomes and Measures: Overall and disease-free survival, postoperative morbidity, and mortality. Results: The analyses included 2549 patients (2206 [86.5%] male; mean [SD] age, 61.0 [9.4] years) from 17 trials (conducted from 1989-2016). Both preoperative CRT plus surgery (hazard ratio [HR], 0.75 [95% credible interval (CrI), 0.62-0.90]; 3-year difference, 105 deaths per 1000 patients) and preoperative and/or perioperative chemotherapy plus surgery (HR, 0.78 [95% CrI, 0.64-0.91]; 3-year difference, 90 deaths per 1000 patients) showed longer overall survival than surgery alone. Comparing the 2 modalities yielded similar overall survival (HR, 1.04 [95% CrI], 0.83-1.28]; 3-year difference, 15 deaths per 1000 patients fewer for CRT). Similarly, disease-free survival was longer for both modalities compared with surgery alone. Postoperative morbidity was more frequent after CRT plus surgery (odds ratio [OR], 2.94 [95% CrI, 1.01-8.59]) than surgery alone. Postoperative mortality was not significantly more frequent after CRT plus surgery than surgery alone (OR, 2.50 [95% CrI, 0.66-10.56]) or after chemotherapy plus surgery than CRT plus surgery (OR, 0.44 [95% CrI, 0.08-2.00]). Conclusions and Relevance: In this meta-analysis of patients with AEG, both preoperative CRT and preoperative and/or perioperative chemotherapy were associated with longer survival without relevant differences between the 2 modalities. Thus, either of the 2 treatments may be recommended to patients.

Functional status and quality of life in older patients with advanced esophageal squamous cell cancer receiving second-line nivolumab ± ipilimumab therapy: A post hoc analysis of the phase 2, multicenter RAMONA study.

INTRODUCTION: The phase 2 RAMONA study demonstrated that second-line nivolumab ± ipilimumab immunotherapy was feasible and effective in older patients with advanced esophageal squamous cell cancer (ESCC). Here, we presented results from functional status (FS) and quality-of-life (QoL) analyses. MATERIALS AND METHODS: Patients aged ≥65 years with advanced ESCC and disease progression following first-line therapy were enrolled for study treatment with nivolumab ± ipilimumab. Geriatric assessments (GA) consisting of G8 and GoGo/SlowGo evaluation, and quality of life (QoL) assessments with EORTC QLQ-C30 questionnaires were conducted at baseline and during the treatment. A post hoc analysis was performed to compare therapy efficacy, toxicity, and QoL between age groups (≥70 years vs. <70 years) and functionality groups (G8 > 14 vs. ≤14 and GoGo vs. SlowGo). RESULTS: In 66 treated patients with a median age of 70.5 years, older patients had non-inferior overall survival and tumor response compared to younger patients, with no increased treatment-related adverse events. Fitter patients (G8 > 14, GoGo) had a clinically, yet not statistically significant, survival advantage than less fit patients (G8 ≤ 14, SlowGo) patients. Moreover, FS by G8 and GoGo/SlowGo significantly correlated with QoL. Overall, QoL was impaired at baseline but remained stable in all scales over the course of immunotherapy. DISCUSSION: The administration of nivolumab ± ipilimumab second-line immunotherapy in older patients with ESCC did not show age-dependent effects and maintained QoL. GA could identify functional deficits and limitations of QoL and should be implemented in the context of immunotherapy. CLINICALTRIALS: gov: NCT03416244.

Clinical impact of panel gene sequencing on therapy of advanced cancers of the digestive system: a retrospective, single center study.

BACKGROUND: Panel gene sequencing is an established diagnostic tool for precision oncology of solid tumors, but its utility for the treatment of cancers of the digestive system in clinical routine is less well documented. METHODS: We retrospectively identified patients with advanced or metastatic gastrointestinal, pancreaticobiliary or hepatic cancers who received panel gene sequencing at a tertiary university hospital from 2015 to 2022. For these cases, we determined the spectrum of genetic alterations, clinicopathological parameters and treatment courses. Assessment of actionability of genetic alterations was based on the OncoKB database, cancer-specific ESMO treatment guidelines, and recommendations of the local molecular tumor board. RESULTS: In total, 155 patients received panel gene sequencing using either the Oncomine Focus (62 cases), Comprehensive (91 cases) or Childhood Cancer Research Assay (2 cases). The mean age of patients was 61 years (range 24-90) and 37% were female. Most patients suffered from either colorectal cancer (53%) or cholangiocellular carcinoma (19%). 327 genetic alterations were discovered in 123 tumor samples, with an average number of 2.1 alterations per tumor. The most frequently altered genes were TP53, KRAS and PIK3CA. Actionable gene alterations were detected in 13.5-56.8% of tumors, according to ESMO guidelines or the OncoKB database, respectively. Thirteen patients were treated with targeted therapies based on identified molecular alterations, with a median progression-free survival of 8.8 months. CONCLUSIONS: Actionable genetic alterations are frequently detected by panel gene sequencing in patients with advanced cancers of the digestive tract, providing clinical benefit in selected cases. However, for the majority of identified actionable alterations, sufficient clinical evidence for targeted treatments is still lacking.

Patients with Advanced or Metastasised Non-Small-Cell Lung Cancer with Viscum album L. Therapy in Addition to PD-1/PD-L1 Blockade: A Real-World Data Study.

Immunotherapy with PD-1/PD-L1 inhibitors has significantly improved the survival rates of patients with metastatic non-small-cell lung cancer (NSCLC). Results of a real-world data study investigating add-on VA (Viscum album L.) to chemotherapy have shown an association with the improved overall survival of patients with NSCLC. We sought to investigate whether the addition of VA to PD-1/PD-L1 inhibitors in patients with advanced or metastasised NSCLC would have an additional survival benefit. In the present real-world data study, we enrolled patients from the accredited national registry, Network Oncology, with advanced or metastasised NSCLC. The reporting of data was performed in accordance with the ESMO-GROW criteria for the optimal reporting of oncological real-world evidence (RWE) studies. Overall survival was compared between patients receiving PD-1/PD-L1 inhibitor therapy (control, CTRL group) versus the combination of anti-PD-1/PD-L1 therapy and VA (combination, COMB group). An adjusted multivariate Cox proportional hazard analysis was performed to investigate variables associated with survival. From 31 July 2015 to 9 May 2023, 415 patients with a median age of 68 years and a male/female ratio of 1.2 were treated with anti-PD-1/PD-L1 therapy with or without add-on VA. Survival analyses included 222 (53.5%) patients within the CRTL group and 193 (46.5%) in the COMB group. Patients in the COMB group revealed a median survival of 13.8 months and patients in the CRTL group a median survival of 6.8 months (adjusted hazard ratio, aHR: 0.60, 95% CI: 0.43-0.85, p = 0.004) after adjustment for age, gender, tumour stage, BMI, ECOG status, oncological treatment, and PD-L1 tumour proportion score. A reduction in the adjusted hazard of death by 56% was seen with the addition of VA (aHR 0.44, 95% CI: 0.26-0.74, p = 0.002) in patients with PD-L1-positive tumours (tumour proportion score > 1%) treated with first-line anti-PD-1/PD-L1 therapy. Our findings suggest that add-on VA correlates with improved survival in patients with advanced or metastasised NSCLC who were treated with PD-1/PD-L1 inhibitors irrespective of age, gender, tumour stage, or oncological treatment. The underlying mechanisms may include the synergistic modulation of the immune response. A limitation of this study is the observational non-randomised study design, which only allows limited conclusions to be drawn and prospective randomised trials are warranted.

[Locally Advanced Rectal Cancer: New Neoadjuvant Strategies and Total Neoadjuvant Therapy]. / Rektumkarzinom: neoadjuvante Strategien und total neoadjuvante Therapie.

Treatment strategies for locally advanced rectal cancer are changing significantly. The treatment recommended in German guidelines for locally advanced tumors of neoadjuvant radio(chemo)therapy (RChT), followed by surgery and, if necessary, adjuvant therapy, are increasingly be abandoned in favor of the following concepts: (i) prolonged neoadjuvant therapy (i.e. "more chemotherapy before resection", referred to as total neoadjuvant therapy, TNT); (ii) organ preservation in patients with a complete clinical response after neoadjuvant radiochemotherapy. (iii) omission of radiotherapy in tumors with a low risk of local recurrence; (iv) definitive treatment with immunotherapy (checkpoint inhibitors) for patients with a primary harboring microsatellite instability (MSI). Herein, current strategies and study concepts are to be discussed based on the guideline-based status quo.

Prioritization and Resource Allocation in the Context of the COVID-19 Pandemic: Recommendations for Colorectal and Pancreatic Cancer in Germany.

In the context of the COVID-19 pandemic, there has been a scarcity of resources with various effects on the care of cancer patients. This paper provides an English summary of a German guideline on prioritization and resource allocation for colorectal and pancreatic cancer in the context of the pandemic. Based on a selective literature review as well as empirical and ethical analyses, the research team of the CancerCOVID Consortium drafted recommendations for prioritizing diagnostic and treatment measures for both entities. The final version of the guideline received consent from the executive boards of nine societies of the Association of Scientific Medical Societies in Germany (AWMF), 20 further professional organizations and 22 other experts from various disciplines as well as patient representatives. The guiding principle for the prioritization of decisions is the minimization of harm. Prioritization decisions to fulfill this overall goal should be guided by (1) the urgency relevant to avoid or reduce harm, (2) the likelihood of success of the diagnostic or therapeutic measure advised, and (3) the availability of alternative treatment options. In the event of a relevant risk of harm as a result of prioritization, these decisions should be made by means of a team approach. Gender, age, disability, ethnicity, origin, and other social characteristics, such as social or insurance status, as well as the vehemence of a patient's treatment request and SARS-CoV-2 vaccination status should not be used as prioritization criteria. The guideline provides concrete recommendations for (1) diagnostic procedures, (2) surgical procedures for cancer, and (3) systemic treatment and radiotherapy in patients with colorectal or pancreatic cancer within the context of the German healthcare system.

Analysis of Burnout Prevalence among German Physicians Working in a Palliative Care Setting: A Survey of the AIO Quality of Life Working Group.

INTRODUCTION: Palliative care physicians (Pcps) face special challenges caring for terminally ill patients. We conducted this study to evaluate the burnout (bo) prevalence among pcps and sought to identify risk as well as protective factors as a basis for the development of preventive measures. METHODS: Participants (Pcs) were invited via e-mail to complete an online survey between May and June 2022. Besides the Oldenburg Burnout Inventory assessing the bo dimensions of exhaustion (exh) and disengagement (dis), sociodemographic data were collected. RESULTS: The study found that 58% (cut-off mean value [M] ≥2.18) or more specifically, 38% (cut-off M ≥2.5) of the pcs showed increased scores in the exh subscale as a key dimension of bo. All dimensions were correlated with the level of medical and palliative care training, with higher scores for physicians in training. Furthermore, pcs without preventive measures like employee appraisals at work were more likely to be considered exhausted, disengaged, or burned out. The discrepancy between high exh and low dis scores shows that the polled pcps, despite feeling exh, nevertheless considered their work meaningful. CONCLUSION: Bo prevalence among pcps exceeds that of the general population and other specialties, whereas inexperienced pcps might be at high risk of shifting from exh to bo and could therefore benefit from tailored support. Further preventive measures including individual and organizational aspects are necessary to prevent bo and promote health among medical staff, thereby preserving quality of patient care. Elementary preventive measures such as employee appraisals can have a protective effect against bo.
