Importance: Existing clinical trials favor neoadjuvant chemoradiation therapy (NCRT) followed by surgery alone for locally advanced esophageal cancer (EC) and perioperative chemotherapy as the preferred modality for esophageal adenocarcinoma (EAC). However, it is unclear whether these trial findings are reflected in the patterns of care and survival outcomes among patients in the clinical setting.Objective: To investigate survival outcomes in the clinical setting among patients with EC after various treatment modalities.Design, Setting, and Participants: This retrospective cohort study examined data from the National Cancer Database maintained by the American College of Surgeons and focused on patients with clinical stage II or III EC, excluding those with gastroesophageal junction cancer, who underwent trimodality therapy (NCRT followed by esophagectomy), definitive chemoradiation therapy (DCRT), radiotherapy (RT) alone, or perioperative chemotherapy from January 2006 to December 2020. Analyses were conducted from December 2023 to August 2024.Exposures: Perioperative chemotherapy, trimodality therapy, DCRT, and single-modality RT.Main Outcomes and Measures: A Cox proportional hazards regression model was used to compare overall survival (OS) between treatment groups in the entire cohort, among patients with squamous cell carcinoma or adenocarcinoma, and among those older than 65 years. Landmark survival analysis at 6 months was performed to reduce survivorship bias.Results: The study included 57 116 patients (median age, 64 [IQR, 57-72] years; 45 410 [79.5%] male); 21 619 patients (37.9%) received trimodality therapy, 32 493 (57.1%) received DCRT, 2692 (4.7%) received single-modality RT, and 312 (0.5%) received perioperative chemotherapy. In the overall study population, 37 698 patients (66.0%) had EAC, and of the 312 patients that received perioperative chemotherapy, 283 (90.7%) had EAC. In adjusted survival analysis, perioperative chemotherapy (adjusted hazard ratio [AHR], 0.33; 95% CI, 0.28-0.39; P <.001) and trimodality therapy (AHR, 0.45; 95% CI, 0.44-0.46; P < .001) were associated with improved OS compared with DCRT. In contrast, RT alone was associated with worse outcomes compared with DCRT (AHR, 1.37; 95% CI, 1.30-1.45; P < .001). The median OS for perioperative chemotherapy of 66.2 months (95% CI, 43.1-111.9 months; P < .001) was longer compared with that for DCRT alone (18.1 months; 95% CI, 17.8-18.4 months; P < .001). Trimodality therapy was associated with a median OS of 43.9 months (95% CI, 42.8-45.5 months; P < .001), which was shorter than that for perioperative chemotherapy but improved compared with DCRT and RT alone, which was associated with a median OS of 13.5 months (95% CI, 12.8-14.0 months; P < .001). In the subgroup of patients older than 65 years, those who received perioperative chemotherapy had longer median OS (56.7 months; 95% CI, 36.4-115.2 months; P < .001) compared with those receiving other treatment modalities (eg, trimodality therapy: 40.1 months; 95% CI, 38.1-42.0 months; P < .001). Patients who received RT alone had the worst median OS (13.6 months; 95% CI, 12.8-14.4 months; P < .001).Conclusions and Relevance: In this cohort study of patients with stage II to III EC, trimodality therapy was associated with improved OS compared with DCRT or RT alone for locally advanced EC and perioperative chemotherapy was associated with improved OS for adenocarcinoma.

Colorectal cancer (CRC), the third most commonly diagnosed and second most lethal cancer worldwide, necessitates efficient early detection strategies to improve patient outcomes. This review evaluates the promise of novel blood-based biomarkers for early detection of CRC. A systematic review, registered with PROSPERO (CRD42024513770) and adhering to PRISMA guidelines, was conducted across multiple databases from January 1st, 2020 to December 31st, 2022. The comprehensive search strategy centered on sensitivity, specificity, and AUC-ROC of multiple types of molecular blood biomarkers. Of total of 142 included articles, 59 were on protein, 58 on RNA, and 21 on DNA. The investigation into DNA biomarkers revealed that cfDNA and ctDNA carry significant potential for early CRC diagnosis. For instance, methylation patterns in genes such as MYO1-G and NDRG4 exhibited high diagnostic accuracies with AUCs reaching up to 0.996. RNA biomarkers like miRNAs and circRNAs also showed promising results, with circ_0011536 achieving AUCs of 0.982. Protein biomarkers, contrasted with established cancer markers, unveiled notable candidates like Irisin and ANXA2, with AUCs surpassing 0.96. The review highlights several individual markers and panels with the potential to improve upon existing CRC screening tests. Despite the promise shown by the novel biomarkers, challenges persist, including small sample sizes, potential selection biases, and a lack of comprehensive cost-effectiveness analysis. Future research should focus on large-scale, multicenter, prospective studies across diverse populations. The findings advocate for an integrated biomarker approach, potentially revolutionizing CRC screening and aligning it with clinical realities through rigorous validation.

The tumor microenvironment (TME) plays an essential role in the development, proliferation, and survival of leukemic blasts in acute myeloid leukemia (AML). Within the bone marrow and peripheral blood, various phenotypically and functionally altered cells in the TME provide critical signals to suppress the anti-tumor immune response, allowing tumor cells to evade elimination. Thus, unraveling the complex interplay between AML and its microenvironment may have important clinical implications and are essential to directing the development of novel targeted therapies. This review summarizes recent advancements in our understanding of the AML TME and its ramifications on current immunotherapeutic strategies. We further review the role of natural products in modulating the TME to enhance response to immunotherapy.

Locally advanced esophageal cancer (LAEC) poses a significant and persistent challenge in terms of effective treatment. Traditionally, the primary strategy for managing LAEC has involved concurrent neoadjuvant chemoradiation followed by surgery. However, achieving a pathologic complete response (pCR) has proven to be inconsistent, and despite treatment, roughly half of patients experience locoregional recurrence or metastasis. Consequently, there has been a paradigm shift towards exploring the potential of immunotherapy in reshaping the landscape of LAEC management. Recent research has particularly focused on immune checkpoint inhibitors, investigating their application in both neoadjuvant and adjuvant settings. These inhibitors, designed to block specific proteins in immune cells, are meant to enhance the immune system’s ability to target and combat cancer cells. Emerging evidence from these studies suggests the possibility of a mortality benefit, indicating that immunotherapy may contribute to improved overall survival rates for individuals grappling with esophageal cancer. This manuscript aims to meticulously review the existing literature surrounding neoadjuvant and adjuvant immunotherapy in the context of LAEC management. The intention is to thoroughly examine the methodologies and findings of relevant studies, providing a comprehensive synthesis of the current understanding of the impact of immunotherapy on esophageal cancer.

Human epidermal growth factor receptor 3 (HER3) is a receptor tyrosine kinase that is expressed in numerous solid tumors. Higher levels of HER3 expression in multiple tumor types are associated with adverse clinical outcomes, such as reduced survival. However, there is currently no HER3-directed antibody-drug conjugate approved for the treatment of any cancer. Improved treatment options are needed, in particular for patients who progress on standard therapies. HER3-DXd is an investigational HER3-directed antibody-drug conjugate composed of an anti-HER3 monoclonal antibody linked to a topoisomerase I inhibitor payload via a stable tetrapeptide-based cleavable linker. In previous clinical trials, HER3-DXd demonstrated a manageable safety profile and durable efficacy in previously treated, advanced EGFR-mutated NSCLC and advanced breast cancer across a range of baseline tumor HER3 expression levels. HER3-DXd has also shown preclinical antitumor efficacy in HER3-expressing cancers including cutaneous melanoma, gastric cancer, and prostate cancer, among others. The aim of this global phase II HERTHENA-PanTumor01 multicohort study is to assess the efficacy and safety of HER3-DXd in patients with relapsed or refractory locally advanced or metastatic solid tumors including melanoma, head and neck squamous cell, gastric/gastroesophageal junction, ovarian, cervical, endometrial, bladder, esophageal squamous cell, pancreatic, and prostate cancers.Clinical trial registration: NCT06172478 (ClinicalTrials.gov); 2023-507641-29-00 (EudraCT); jRCT2031230575 (Japan Registry of Clinical Trials).

In the past decade, targeted therapies for solid tumors, including non-small cell lung cancer (NSCLC), have advanced significantly, offering tailored treatment options for patients. However, individuals without targetable mutations pose a clinical challenge, as they may not respond to standard treatments like immune-checkpoint inhibitors (ICIs) and novel targeted therapies. While the mechanism of action of ICIs seems promising, the lack of a robust response limits their widespread use. Although the expression levels of programmed death ligand 1 (PD-L1) on tumor cells are used to predict ICI response, identifying new biomarkers, particularly those associated with the tumor microenvironment (TME), is crucial to address this unmet need. Recently, inflammatory cytokines such as interleukin-1 beta (IL-1β) have emerged as a key area of focus and hold significant potential implications for future clinical practice. Combinatorial approaches of IL-1β inhibitors and ICIs may provide a potential therapeutic modality for NSCLC patients without targetable mutations. Recent advancements in our understanding of the intricate relationship between inflammation and oncogenesis, particularly involving the IL-1β/PD-1/PD-L1 pathway, have shed light on their application in lung cancer development and clinical outcomes of patients. Targeting these pathways in cancers like NSCLC holds immense potential to revolutionize cancer treatment, particularly for patients lacking targetable genetic mutations. However, despite these promising prospects, there remain certain aspects of this pathway that require further investigation, particularly regarding treatment resistance. Therefore, the objective of this review is to delve into the role of IL-1β in NSCLC, its participation in inflammatory pathways, and its intricate crosstalk with the PD-1/PD-L1 pathway. Additionally, we aim to explore the potential of IL-1β as a therapeutic target for NSCLC treatment.
