Emailed
Shi Si et al., Cancer Cell

Single-arm phase 1/2 trial in previously treated metastatic KRAS G12D-mutant pancreatic cancer, published in Cancer Cell. A chemotherapy-free KRAS G12D inhibitor plus PD-L1 blockade combination showed encouraging, durable responses in this refractory population, warranting further study.

Advances in therapeutic approaches to gastric cancer.
Not selected
Wang Feng et al., CA Cancer J Clin

Comprehensive narrative review of current therapeutic approaches across gastric cancer stages, published in CA Cancer J Clin. Summarizes evolving standards including perioperative immunotherapy, claudin 18.2-targeted therapy, and antibody-drug conjugates, informing overall management strategy.

Medicaid Expansion and Mortality Among Patients With Colorectal Cancer.
Not selected
Akinyemi Oluwasegun et al., JAMA Netw Open

Large retrospective difference-in-differences cohort study using the National Cancer Database examining Medicaid expansion and colorectal cancer survival, published in JAMA Network Open. Finds expansion associated with lower mortality, informing policy and access discussions relevant to equitable cancer care delivery.

Circulating tumor DNA-guided de-escalation or escalation of adjuvant therapy in high-risk stage II and stage III colon cancer: the phase 2 PEGASUS trial.
Website only
Marsoni Silvia et al., Nat Cancer

Single-arm phase 2 trial (PEGASUS) in resected high-risk stage II/III colon cancer, published in Nature Cancer, testing a ctDNA-guided adaptive strategy to escalate or de-escalate adjuvant chemotherapy. Primary endpoint was not met, but the approach showed reduced neurotoxicity versus historical controls, offering exploratory support for biomarker-guided de-escalation strategies.

Circulating free bacterial DNA as a novel biomarker for monitoring therapy response in patients with advanced pancreatic cancer.
Not selected
Surendran Sai Agash et al., Eur J Cancer

Translational biomarker study with an exploratory cohort and validation in the NEOLAP trial cohort of advanced pancreatic cancer patients, published in Eur J Cancer. Circulating bacterial DNA dynamics during chemotherapy tracked with outcomes differently by regimen (FOLFIRINOX vs gemcitabine/nab-paclitaxel), suggesting a potential blood-based tool to guide treatment monitoring and regimen selection.

Pancreatic ductal adenocarcinoma: The Vision of Heracles.
Not selected
Mota Reyes Carmen et al., Cancer Cell

Narrative review/perspective on pancreatic ductal adenocarcinoma biology and resistance mechanisms, published in Cancer Cell. Proposes a conceptual framework for precision interception and future therapeutic strategies rather than reporting new clinical data.

Liquid biopsy for early detection of pancreatic ductal adenocarcinoma.
Not selected
Xu Caiming et al., Nat Med

Prospective international biomarker study developing a blood-based microRNA assay combined with CA19-9 for early detection of pancreatic ductal adenocarcinoma, published in Nature Medicine. Shows promising sensitivity for early-stage disease and potential for monitoring recurrence, though it addresses screening/detection rather than treatment selection.

Quality of life in patients with RAS wild-type metastatic colorectal cancer treated mFOLFOXIRI + panitumumab versus FOLFOXIRI: A prespecified secondary analysis of the phase II VOLFI AIO-KRK 0109 trial.
Not selected
Klingler Tshilidzi M et al., Eur J Cancer

Prespecified secondary quality-of-life analysis from the phase II VOLFI trial in untreated RAS wild-type metastatic colorectal cancer, published in European Journal of Cancer. Shows adding panitumumab to FOLFOXIRI does not meaningfully worsen overall quality of life despite added skin toxicity, supporting its use as a first-line option.

Triplet chemotherapy with Gemcitabine, Nab-paclitaxel, and S-1 achieves high response and conversion rates in advanced pancreatic cancer: A multicenter phase II study (GeNeS1S trial).
Not selected
Nagatani Yoshiaki et al., Eur J Cancer

Single-arm multicenter phase 2 trial in previously untreated advanced pancreatic cancer, published in Eur J Cancer, testing a gemcitabine/nab-paclitaxel/S-1 triplet regimen. Shows promising response and conversion-to-surgery rates, suggesting a potential new option pending randomized confirmation.

Statin Initiation and Mortality After Colorectal Cancer Treatment.
Not selected
Woo Hyeong-Taek et al., JAMA Netw Open

Target-trial-emulation cohort study using Korean national claims data, published in JAMA Network Open, examining whether starting a statin after colorectal cancer treatment is associated with lower cancer-specific and all-cause mortality. Suggests a possible survival benefit from statin initiation but remains observational and hypothesis-generating rather than practice-changing.

Oncological impact of adjuvant chemotherapy after rectal cancer excision in the era of FOLFIRINOX-based TNT: A pooled post-hoc analysis of GRECCAR4-PRODIGE23.
Not selected
Denost Quentin et al., Eur J Cancer

Post-hoc pooled subgroup analysis of the GRECCAR4 and PRODIGE23 randomized trials examining whether adjuvant chemotherapy adds benefit after total neoadjuvant therapy in locally advanced rectal cancer, published in European Journal of Cancer. Suggests adjuvant chemotherapy benefit seen after chemoradiotherapy alone may not extend to patients who already received FOLFIRINOX-based TNT, informing decisions about omitting adjuvant chemotherapy after TNT.

CD28-ICOS costimulation enhances the therapeutic efficacy of L1CAM-targeted CAR-T cells against ovarian and gastric cancers.
Not selected
Che Xiumei et al., J Immunother Cancer
