    1. Exceptional responders with invasive mucinous adenocarcinomas: a phase 2 trial of bortezomib in patients with KRAS G12D-mutant lung cancers

      [Paper-level Aggregated] PMCID: PMC6549573

      Evidence Type(s): Oncogenic, Predictive, Prognostic

      Justification: Oncogenic: The KRAS G12D mutation is described as a characteristic of the lung adenocarcinomas being studied, indicating its role in the oncogenesis of these tumors. Predictive: The text mentions that KRAS G12D mutation alone is not a robust predictor of response to bortezomib, suggesting its potential role in predicting treatment outcomes, albeit not reliably. Prognostic: The overall survival and progression-free survival data provided in the study suggest that the presence of the KRAS G12D mutation may have implications for the prognosis of patients with advanced NSCLC.

    2. Contrary to what might have been predicted by preclinical data, TP53 was not found to be mutated or p53 aberrantly expressed in an examination of tumor from the exceptional responder on this trial. Next-generation sequen

      Evidence Type(s): Oncogenic

      Justification: Oncogenic: The presence of the KRAS G12D mutation is discussed in the context of tumor analysis, indicating its role in contributing to tumor development or progression, particularly as it is mentioned alongside other mutations in a patient with no observed responses.

    3. Following the preclinical observation that significant tumor regression and prolonged survival were only observed in KRAS G12D models with p53 deficiency (KRASLSL-G12D/wt;p53flox/flox mice) compared to p53-intact models

      [Paragraph-level] PMCID: PMC6549573 Section: RESULTS PassageIndex: 11

      Evidence Type(s): Oncogenic, Prognostic

      Justification: Oncogenic: The passage discusses the KRAS G12D variant in the context of tumor regression and survival in specific mouse models, indicating its role in tumor development or progression. Prognostic: The mention of prolonged survival in the context of the KRAS G12D variant suggests a correlation with disease outcome, independent of therapy.

    4. Although bortezomib did not induce responses in the majority of patients with KRAS G12D-mutant lung adenocarcinomas on this phase 2 trial, dramatic disease shrinkage was observed in an exceptional responder. An 80-yr-old

      [Paragraph-level] PMCID: PMC6549573 Section: RESULTS PassageIndex: 8

      Evidence Type(s): Predictive, Diagnostic, Oncogenic

      Justification: Predictive: The passage discusses the response to bortezomib in patients with KRAS G12D-mutant lung adenocarcinomas, indicating a correlation between the variant and treatment response. Diagnostic: The KRAS G12D mutation is identified through molecular profiling as part of the patient's diagnosis, linking the variant to the classification of the disease. Oncogenic: The KRAS G12D mutation is described in the context of tumor development and progression, as it is a known driver mutation in lung adenocarcinomas.

    5. Of the 16 patients accrued to the first stage of this study, only one confirmed PR was observed. Complete responses were not observed. SD was achieved in five patients, and a best response of disease progression was note

      [Paragraph-level] PMCID: PMC6549573 Section: RESULTS PassageIndex: 4

      Evidence Type(s): Predictive, Diagnostic, Oncogenic

      Justification: Predictive: The passage discusses the response of patients with KRAS G12D-mutant lung cancers to bortezomib, indicating a correlation between the variant and treatment response. Diagnostic: The mention of KRAS G12D in the context of lung cancers suggests its role in classifying or defining a specific subtype of the disease. Oncogenic: The variant KRAS G12D is implicated in lung cancers, indicating its contribution to tumor development or progression.

      Evidence Type(s): Predictive, Diagnostic, Oncogenic

      Justification: Predictive: The passage discusses patients with KRAS G12D-mutant lung cancers treated with bortezomib, indicating a correlation between the variant and response to therapy. Diagnostic: The mention of "KRAS G12D-mutant lung cancers" suggests that the variant is used to classify or define a specific subtype of lung cancer. Oncogenic: The variant KRAS G12D is implicated in the context of lung adenocarcinoma, indicating its role in tumor development or progression.
