Precision oncology is a multi-step process including patient selection, tumor profiling, molecular tumor board discussion and personalized cancer management. So far, it remains largely unstandardized. The implementation of precision oncology can be beneficial for patients but implementation differs widely between tumor types and local practices. A working group was established by the Austrian, German and Swiss societies for Hematology and Medical Oncology to establish an expert consensus on evidence-based standards and implementation of precision oncology.

Background

Several first-line therapeutic strategies have been evaluated alongside platinum-based chemotherapy in advanced or recurrent endometrial cancer (a/rEC). However, the optimal approach remains unclear.

Methods

A systematic review was conducted to identify randomized control trials (RCTs) that evaluate first-line therapeutic strategies in a/rEC involving immune checkpoint inhibitors (ICI) and PARP inhibitors (PARPi). A network meta-analysis with a frequentist framework using random-effects and an extracted individual patient data meta-analysis were performed. The primary endpoint was progression-free survival (PFS) by MMR status, p53 status within the MMRp population and PD-L1 status.

Results

A total of 3210 patients with EC were included. In the MMRp population, the combination (ICI and PARPi) showed a not statistically significant PFS benefit compared with each agent alone. In MMRp p53-abnormal patients (n = 590), combining PARPi and ICI statistically improved PFS compared to ICI alone (HR=0.47, 95 %CI 0.40–0.94) with a numerically better outcome compared to PARPi alone (HR=0.63, 95 %CI 0.26–1.57). No benefit from PARPi was observed in the p53 wild-type MMRp population. PD-L1-positivity (n = 1121) appears to predict more benefit from the addition of ICI and PARPi, with a larger benefit of combination therapy. In the MMRd population (n = 769), the best outcomes were observed with ICI alone, with no additional benefit of PARPi. Grade 3 or greater treatment-related adverse events were seen in 75.1 % patients treated with the combination.

Conclusions

The addition of the combination of ICI and PARPi to platinum-based chemotherapy provides greatest benefit to p53-abnormal MMRp patients. PD-L1 is a potentially useful biomarker with PD-L1-positive tumors more likely to respond to ICI. Implementation of biomarkers is crucial to redefine the treatment paradigm in a/rEC.
背景在对晚期或复发性子宫内膜癌(a/rEC)进行铂类化疗的同时,还对多种一线治疗策略进行了评估。方法进行了一项系统综述,以确定对涉及免疫检查点抑制剂(ICI)和 PARP 抑制剂(PARPi)的 a/rEC 一线治疗策略进行评估的随机对照试验(RCT)。采用随机效应的频数主义框架进行了网络荟萃分析,并对提取的单个患者数据进行了荟萃分析。主要终点是按MMR状态、MMRp人群中的p53状态和PD-L1状态划分的无进展生存期(PFS)。在MMRp人群中,与单用每种药物相比,联合用药(ICI和PARPi)的PFS获益无统计学意义。在 p53 正常的 MMRp 患者(n = 590)中,与单用 ICI 相比,联合使用 PARPi 和 ICI 可在统计学上改善 PFS(HR=0.47,95 %CI 0.40-0.94),与单用 PARPi 相比,疗效更好(HR=0.63,95 %CI 0.26-1.57)。在p53野生型MMRp人群中未观察到PARPi带来的益处。PD-L1 阳性(n = 1121)似乎预示着 ICI 和 PARPi 的联合治疗可带来更多获益,联合治疗的获益更大。在MMRd人群(n = 769)中,单用ICI可获得最佳疗效,PARPi则无额外获益。在接受联合治疗的患者中,75.1%的患者出现了3级或更严重的治疗相关不良事件。PD-L1是一种潜在的有用生物标志物,PD-L1阳性的肿瘤更有可能对ICI产生反应。生物标志物的应用对于重新定义 a/rEC 的治疗模式至关重要。

Purpose

Artificial intelligence (AI) could reduce lung cancer screening computer tomography (CT)-reading workload if used as a first-reader, ruling-out negative CT-scans at baseline. Evidence is lacking to support AI performance when compared to gold-standard lung cancer outcomes. This study validated the performance of a commercially available AI software in the UK lung cancer screening (UKLS) trial dataset, with comparison to human reads and histological lung cancer outcomes, and estimated CT-reading workload reduction.

Methods

1252 UKLS-baseline-CT-scans were evaluated independently by AI and human readers. AI performance was evaluated on two-levels. Firstly, AI classification and individual reads were compared to a EU reference standard (based on NELSON2.0-European Position Statement) determined by a European expert panel blinded from individual results. A positive misclassification was defined as a nodule positive read ≥ 100mm3 and no/<100mm3 nodules in the expert read; A negative misclassification was defined as a nodule negative read, whereas an indeterminate or positive finding in the expert read. Secondly, AI nodule classification was compared to gold-standard histological lung cancer outcomes. CT-reading workload reduction was calculated from AI negative CT-scans when AI was used as first-reader.

Results

Expert panel reference standard reported 815 (65 %) negative and 437 (35 %) indeterminate/positive CT-scans in the dataset of 1252 UKLS-participants. Compared to the reference standard, AI resulted in less misclassification than human reads, NPV 92·0 %(90·2 %-95·3 %). On comparison to gold-standard, AI detected all 31 baseline-round lung cancers, but classified one as negative due to the 100mm3 threshold, NPV 99·8 %(99·0 %-99·9 %). Estimated maximum CT-reading workload reduction was 79 %.

Conclusion

Implementing AI as first-reader to rule-out negative CT-scans, shows considerable potential to reduce CT-reading workload and does not lead to missed lung cancers.

Background

Entrectinib, a central nervous system (CNS)-penetrant TRK/ROS1 inhibitor, has demonstrated clinical activity in children with NTRK1/2/3 or ROS1 fusion-positive extracranial solid and CNS tumours. We present integrated data of entrectinib in children with NTRK or ROS1 fusion-positive tumours from the STARTRK-NG, TAPISTRY, and STARTRK-2 trials.

Methods

Efficacy analyses were undertaken on TRK/ROS1 inhibitor-naïve patients aged <18 years with metastatic/locally advanced NTRK1/2/3 or ROS1 fusion-positive extracranial solid or CNS tumours who received ≥1 entrectinib dose and had ≥6 months of follow-up from enrolment. Tumour responses were confirmed by blinded independent central review (BICR) per RECIST v1.1/RANO criteria. Primary endpoint: BICR-assessed confirmed objective response rate (cORR). Key secondary endpoints: duration of response (DoR); time to response (TtR); safety.

Results

As of 16 July 2023, out of 91 safety-evaluable patients, 64 (NTRK: n=44; ROS1: n=20) were efficacy evaluable. In the NTRK and ROS1 subgroups, respectively, median age was 4.0 years and 7.5 years; median survival follow-up was 24.2 months and 27.6 months. cORR was 72.7 % (NTRK, 95 % confidence interval [CI]: 57.2–85.0) and 65.0 % (ROS1, 95 % CI: 40.8–84.6). Median DoR was not reached (NTRK, 95 % CI: 25.4–not evaluable [NE]); ROS1, 95 % CI: 16.2–NE); median TtR was 1.9 months in both subgroups. The most frequently reported treatment-related adverse events included weight gain (35.2 %) and anaemia (31.9 %).

Conclusion

Integrated data from three trials confirm entrectinib induces rapid and durable responses in children with NTRK or ROS1 fusion-positive tumours. The increased duration of safety monitoring does not demonstrate new or cumulative toxicity.

Background

As adjuvant chemotherapy for stage III gastric cancer, the phase III (JACCRO GC-07) trial showed that docetaxel plus S-1 (DS) was superior to S-1 in terms of recurrence-free and overall survival. However, whether adding docetaxel to S-1 in the adjuvant setting affects survival after recurrence remains unclear. The optimal treatment strategy for patients who develop recurrence during or after DS has also been controversial.

Methods

We used results from JACCRO GC-07 to investigate post-recurrence survival (PRS) in patients who developed recurrence during or after completing adjuvant chemotherapy. PRS was compared between adjuvant groups and among post-recurrence chemotherapeutic regimens.

Results

During 5 years of follow-up after surgery, 161 of 441 patients in the DS group and 216 of 452 patients in the S-1 group developed recurrence, with median PRS of 12.6 and 11.4 months, respectively (hazard ratio [HR] 0.98, 95 % confidence interval [CI] 0.79–1.22; p = 0.84). Among patients with recurrence, 115 patients in the DS group and 165 patients in the S-1 group received chemotherapy, and median PRS was 14.5 and 13.7 months, respectively (HR 1.04, 95 %CI 0.81–1.34; p = 0.76). Platinum-based chemotherapy resulted in longer PRS than non-platinum chemotherapy, regardless of the adjuvant chemotherapeutic regimen or time of recurrence.

Conclusions

PRS was similar between patients who received adjuvant chemotherapy with DS or with S-1 alone. PRS was also similar between groups of patients who received chemotherapy after recurrence.

Purpose

To explore why in large phase III randomized clinical trials TP53-mutated (TP53mut) endometrial cancer (EC) was the only tumor showing survival benefit to immune checkpoint inhibitors (ICIs) added to chemotherapy when compared with other low TMB TP53mut cancers, such as high-grade serous ovarian (HGSOC) and triple-negative breast cancer (TNBC).

Experimental Design

From 606 patients with one of the three mentioned cancers, “The Cancer Genome Atlas” data on clinical outcome, TMB and detailed composition of the tumor immune-microenvironment (TIME) (immune infiltrating cells, cytokines, and other immune-modulators) were compared using the Kruskal-Wallis test, followed by Pearson correlation. Prognostic value of studied variables was assessed by Kaplan-Meier and Cox-regression analyses.

Results

TMB was very low in all three TP53mut entities, being lowest in EC (median: 1.27 Mut/Mb; p < 0.001). Interestingly, high TMB was significantly associated with improved clinical outcome in every entity, whereby best discrimination for PFS was found in EC (HR: 0.52). Compared to EC, immune-suppressing regulatory T-cells were higher in HGSOC and TNBC (p < 0.001) and M2-like macrophages higher in HGSOC (p < 0.001). In contrast, immune-activating mDCs were more prominent in EC than in HGSOC (p < 0.001). Differential modulator expression analyses revealed highest discrimination for the immune-inhibiting FOXP3, C1QA and XBP1, which all exhibited lower levels in EC compared with HGSOC and TNBC (p < 0.001).

Conclusion

Characteristics of TIME differ substantially among the assessed entities in terms that EC exhibits fewer immunosuppressive traits, expecting a higher likelihood for responding to ICIs, despite a very low TMB, whereas HGSOC and TNBC exhibit an immune hostile TIME.

Background

Interest in metastatic solid tumors patients achieving exceptionally durable responses to systemic treatment is progressively increasing; however, available evidence still remains limited. This study characterizes patients with metastatic breast cancer (mBC) achieving an exceptional response, with a focus on patients discontinuing systemic treatment.

Methods

In this retrospective monocentric study, patients with mBC achieving exceptional responses (2021–2023) were identified; clinical features, hormone receptor (HR) and HER2 status, and radiological responses were collected. Exceptional response was defined as complete (CR) or partial response (PR) lasting for more than twice the expected progression-free survival (PFS). No evidence of disease (NED) was defined as radiological absence of disease achieved integrating locoregional treatments.

Results

We identified 58 exceptional responders: 31 HER2+ (53.5 %), 16 HR+ /HER2- (27.6 %), and 11 HR-/HER2- (19.0 %). 5-year PFS was 89.1 % and 5-year OS was 94.6 % overall, and numerically better in HR-/HER2- mBC (5-year PFS/OS: 100 %) compared to HER2+ (90.2 %/93.5 %) and HR+ /HER2- (80.8 %/93.8 %) mBC.
Best radiological response was CR/NED in 69.0 % and PR in 31.0 % of patients. CR/NED status was significantly associated with better outcomes compared to PR (5-year OS: 100 % vs. 83.0 %, p = 0.004). Eleven patients (9 with CR/NED, 2 with PR) discontinued treatment in absence of disease progression; subsequent progression was observed only in one patient with PR.

Conclusion

mBC patients achieving exceptional responses exhibit favorable long-term survival outcomes, particularly if achieving CR/NED. These findings highlight the importance of further research to refine management strategies and explore the potential for systemic treatment discontinuation in these patients.
