Article Synopsis
  • - This study investigates how specific genetic variants affect survival and recurrence in patients with different types of biliary tract cancers (BTCs), focusing on intrahepatic cholangiocarcinoma (IHC), extrahepatic cholangiocarcinoma (EHC), and gallbladder adenocarcinoma (GB).
  • - Out of 985 patients analyzed, 15% had significant mutations, with IHC and EHC showing the highest mutation rates (38% and 37%, respectively). Patients with mutations in IHC had a notably worse survival rate compared to those with wild-type tumors.
  • - The findings highlight that G12 mutations in IHC are particularly detrimental to patient outcomes, underscoring the need for tailored therapies

Article Synopsis
  • Adjuvant mFOLFIRINOX (mFFX) is a standard treatment for patients with resected pancreatic ductal adenocarcinoma (PDAC), but there is limited information on its effectiveness outside of clinical trials.
  • A study of 147 patients showed a median recurrence-free survival (RFS) of 26 months, with some patients over 70 years experiencing a median overall survival (OS) of 51 months.
  • Starting mFFX treatment within 8 weeks of surgery was linked to better survival outcomes, while certain genetic factors like KRAS mutations suggested poorer RFS and OS.

Article Synopsis
  • Hepatic artery infusion (HAI) chemotherapy combined with systemic treatment shows promising long-term results for patients with intrahepatic cholangiocarcinoma (IHC), suggesting improved disease control and overall survival rates.
  • A phase II clinical trial and a retrospective analysis revealed a median progression-free survival (PFS) of 11.8 months and overall survival (OS) of 26.8 months among a subset of patients, with particular genomic alterations indicating worse outcomes.
  • The study indicates that HAI with floxuridine (FUDR) alongside systemic therapies can provide durable disease control in locally advanced IHC, while molecular changes, particularly in the TP53 pathway, might help predict patient response to treatment.

Article Synopsis
  • A new method called robotic pancreatoduodenectomy (RPD) is becoming popular, but it's challenging to start using it safely without on-site experts.
  • A detailed plan was created to help hospitals introduce RPD using online help from experienced doctors.
  • After starting the program, they performed RPD on 68 patients and found that the surgery time got shorter with experience, and most surgeries had excellent results.

Article Synopsis
  • Ampullary adenocarcinoma (AA) shows clinical and genetic diversity, and a new genomic classifier may improve patient classification beyond traditional methods, but it needs validation before being widely used.
  • A study involving 192 patients with AA assessed the accuracy of this genomic classifier against standard histology to see if it could predict survival outcomes.
  • Results indicated a 55% agreement between genomic and histological classifications; however, while histological subtypes did not predict survival, the genomic scores did correlate with survival probabilities, suggesting the genomic approach might be more effective.

KRAS mutations in pancreatic ductal adenocarcinoma (PDAC) are suggested to vary in oncogenicity but the implications for human patients have not been explored in depth. We examined 1,360 consecutive PDAC patients undergoing surgical resection and find that KRAS mutations are enriched in early-stage (stage I) disease, owing not to smaller tumor size but increased node-negativity. KRAS tumors are associated with decreased distant recurrence and improved survival as compared to KRAS.

Circulating extracellular vesicles and particles (EVPs) are being investigated as potential biomarkers for early cancer detection, prognosis, and disease monitoring. However, the suboptimal purity of EVPs isolated from peripheral blood plasma has posed a challenge of in-depth analysis of the EVP proteome. Here, we compared the effectiveness of different methods for isolating EVPs from healthy donor plasma, including ultracentrifugation (UC)-based protocols, phosphatidylserine-Tim4 interaction-based affinity capture (referred to as "PS"), and several commercial kits.

Background: Management of intrahepatic cholangiocarcinoma (IHC) has advanced in recent decades, including randomized trial evidence supporting systemic therapy in the palliative and adjuvant setting. Mounting observational evidence suggests resection of IHC with multifocal disease (IHC-MF) or lymph node metastasis (IHC-LNM) should be limited. It is unknown how real-world practice has evolved in light of research advances.

Metastasis occurs frequently after resection of pancreatic cancer (PaC). In this study, we hypothesized that multi-parametric analysis of pre-metastatic liver biopsies would classify patients according to their metastatic risk, timing and organ site. Liver biopsies obtained during pancreatectomy from 49 patients with localized PaC and 19 control patients with non-cancerous pancreatic lesions were analyzed, combining metabolomic, tissue and single-cell transcriptomics and multiplex imaging approaches.
