Special Issue Information

Dear Colleagues,

Gastrointestinal cancers represent a highly heterogeneous group of malignancies arising from the esophagus, stomach, small bowel, colon, rectum, pancreas, liver, and biliary tract, as well as a spectrum of neuroendocrine tumors located throughout the digestive system. Their therapeutic management and clinical outcomes have evolved rapidly over the past decade, driven by innovations in diagnostics, minimally invasive interventions, systemic therapies, and multidisciplinary care pathways.

This second edition will build upon the success of the previous Special Issue, which featured 11 published articles, and will broaden the scientific scope to reflect the full range of current and emerging treatment modalities, both surgical and non-surgical.

Advances in endoscopic therapy have transformed the management of early-stage gastrointestinal neoplasia, enabling curative-intent treatment for selected cases of early gastric cancer, early esophageal squamous cell carcinoma and adenocarcinoma, rectal lesions, and duodenal or rectal neuroendocrine tumors through techniques such as EMR, ESD, EFTR, and hybrid procedures.

At the same time, systemic and medical oncology treatments—including chemotherapy, targeted therapies, and rapidly expanding immunotherapy options—have redefined outcomes for patients with advanced or non-surgical GI cancers. Precision oncology, molecular profiling, and biomarker-driven treatment selection are now playing an increasingly central role in therapeutic decision-making, helping clinicians tailor interventions to individual tumor biology.

Surgical management has also progressed significantly, with open, laparoscopic, and robotic platforms delivering improved perioperative and functional outcomes. Enhanced preoperative staging, multimodal treatment planning, and advanced imaging support optimized decision-making across the entire disease spectrum.

For this Special Issue, we will prioritize research on clinical outcomes with clear, quantifiable endpoints such as overall survival, disease-free survival, cancer-specific survival, progression-free survival, treatment-related morbidity, quality of life, and functional outcomes.

This Special Issue will showcase high-quality research and state-of-the-art reviews covering the full continuum of care for gastrointestinal malignancies, including the following topics:

  • Surgical, endoscopic, and interventional techniques;
  • Systemic therapy, immunotherapy, and targeted molecular treatments;
  • Multidisciplinary clinical pathways and treatment sequencing;
  • Precision diagnostics, biomarkers, and individualized treatment strategies;
  • Short- and long-term oncological, functional, and quality-of-life outcomes;
  • Emerging technologies and future directions in GI cancer management.

We welcome original research articles, clinical studies, systematic reviews, meta-analyses, and translational insights that contribute to improved therapeutic decision-making and patient-centered outcomes in gastrointestinal oncology.

Background/Objectives: Several chemotherapeutic regimens and targeted therapies are currently established as standard second-line treatments for patients with advanced biliary tract cancer (BTC). However, evidence regarding the benefits of treatment after first-line therapy failure remains limited, particularly among Thai populations. This study aimed to explore the efficacy of second-line chemotherapy in patients with advanced BTC. Methods: We conducted a single-institution, retrospective study including patients with locally advanced or metastatic BTC who experienced disease progression following first-line treatment between January 2017 and December 2019. Overall survival (OS) was defined as the primary endpoint. The secondary endpoint was the restricted mean survival time (RMST). To minimize confounding, propensity scores were estimated and applied using inverse probability of treatment weighting (IPTW). Results: A total of 110 patients were included, of whom 69 (62%) received second-line chemotherapy in combination with best supportive care (2LCMT + BSC), while 41 (38%) received best supportive care (BSC) alone. The majority of cases were intrahepatic cholangiocarcinoma (73.9% and 70.7% in each group, respectively). The median OS was 5.3 months (95% CI 3.5–7.0) in the 2LCMT + BSC group and 1.0 months (95% CI 0.5–1.9) in the BSC-only group (unadjusted HR 0.40, 95% CI 0.26–0.59; p < 0.001). In IPTW-adjusted flexible parametric regression analysis, second-line chemotherapy was associated with a 53% reduction in the risk of death compared with BSC alone (p = 0.009). The restricted mean survival time (RMST) differences between groups at 3, 6, and 12 months were 1.3 months (95% CI 0.9–1.6; p < 0.001), 2.6 months (95% CI 1.9–3.3; p < 0.001), and 3.9 months (95% CI 2.7–5.1; p < 0.001), sequentially. Conclusions: These findings demonstrate that second-line chemotherapy provides a significant overall survival benefit compared with best supportive care alone in patients with advanced BTC.
