Epidemiologic trends and survival outcomes in patients with primary digestive system lymphoma in the United States.

Primary digestive system lymphoma (PDSL) is an important entity of extranodal lymphoma, yet updated epidemiologic and survival data are lacking. Patients diagnosed with PDSL between 1975 and 2020 were identified from the Surveillance, Epidemiology, and End Results database. Kaplan-Meier analysis estimated survival outcomes. Multivariable Cox regression identified independent risk factors, and nomograms were developed to predict 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS). A total of 30,568 patients with PDSL were identified, with 57.9% being male and 80.4% white. The most frequent tumor site was the stomach (48.7%) and diffuse large B-cell lymphoma (DLBCL) was the predominant histologic subtype (45.0%). The overall incidence from 2016 to 2020 was 11.11 per 1,000,000 persons, with a decrease observed in lymphoma rates for the stomach, small intestine, large intestine, and pancreas. Long-term trends showed an initial rise in PDSL incidence, followed by a decline since the 1990s. The median OS across all patients was 103months, with appendiceal lymphoma showing the highest median OS of 253months. Factors including diagnosis year, age, sex, race, primary tumor site, histologic subtype, stage, and treatment modalities were significantly associated with OS and CSS. Nomograms achieved C-indices of 0.720 for OS and 0.723 for CSS in the training cohort. The incidence of PDSL initially increased but has recently declined. Survival for all PDSL patients has improved over time. Nomograms to predict survival for patients with DLBCL exhibited good predictive and discriminating abilities.

Small renal mass: which criteria are decisive for a tumor board?

Small renal masses (SRM) are aheterogeneous group of tumors with varying metastatic potential. The increasing use and improvement in the quality of abdominal imaging have led to an increasingly earlier diagnosis of incidental SRM, which are asymptomatic and confined to the organ. Despite these advances in imaging and the growing use of renal tumor biopsies, preoperative diagnosis of malignancy remains difficult. The treatment of SRM has shifted away from radical nephrectomy and now primarily includes organ-sparing surgery or active surveillance. The optimal strategy for treating SRM is continuously evolving as studies from prospective data registries can identify factors that influence both short- and long-term patient outcomes. Recent research on biomarkers, imaging techniques, and machine learning offer promising approaches to adeeper understanding of tumor biology and treatment options for this patient population.

MiR‐21‐Trigged Precise Photodynamic Therapy Through a “Locking‐Unlocking‐Boosting” ROS Production Strategy

AbstractPhotodynamic therapy (PDT) stands out as a highly promising modality for tumor treatment, yet previous works have primarily centered around either boosting the production of reactive oxygen species (ROS) in tumor tissues or restricting it in normal tissues. The current challenge lies in the urgent need to achieve precise modulation of ROS production by simultaneously controlling both aspects. To achieve this goal, a precise PDT platform through a “locking‐unlocking‐boosting” ROS production strategy is presented, in which the generation of ROS is modulated by bidirectionally regulating the upconversion luminescence (UCL) of lanthanide‐doped nanoparticles (LnNPs), thus ROS production is “locked” in normal tissues but “boosted” in tumor tissues. In detail, by introducing an energy acceptor BHQ3, the UCL is initially quenched to prevent Chlorin e6 (Ce6) from generating ROS. However, under the tumor microenvironment with overexpressed miR‐21, LnNPs are sequestered from BHQ3 to “unlock” ROS generation and then assembled with QDs@B2, which functions as an antenna to sensitize LnNPs luminescence, to further “boost” ROS generation. With the assistance of spherical nucleic acids, this therapeutic agent effectively traverses the blood‐brain barrier (BBB), enabling efficient PDT for glioblastoma.

Efficacy and safety of systemic treatment for progressive and refractory desmoid tumor: a systematic review and Bayesian network meta-analysis.

Desmoid tumors (DT) are rare, locally invasive tumors originating from connective tissue. Surgical intervention is no longer the standard treatment for DT, as systemic therapy gradually replaces it due to its superior efficacy. Despite the availability of various treatment modalities, there is a need for a first-line systemic treatment regimen that offers both effective disease control and acceptable safety profiles. To assess the efficacy and safety of different systemic treatment agents for DT, we conducted a systematic review and network meta-analysis. Eligible studies were identified through searches of PubMed, Embase, and the Cochrane Library databases, and data were extracted according to predefined inclusion criteria. Three articles and clinical data from 295 patients with progressive and refractory DT were included in this Bayesian network meta-analysis. When considered by objective response rate (ORR), the efficacy of γ-secretase inhibitor versus placebo (OR 0.12, 95%CI 0.01-1.68) is superior to that of TKI (OR 0.49, 95%CI 0.03-7.62) and chemotherapy (OR 0.90, 95%CI 0.02-40.00). Vascular endothelial growth factor (VEGF)-TKI (OR, 0.09; 95% CI, 0.01-1.79) seemed to have the highest improvement in terms of 1-yr PFS rate, while chemotherapy seemed to have the highest improvement across all therapies in terms of 2-yr PFS rate across all therapies (OR, 0.06; 95 percent CI, 0.01-2.98). In terms of safety, the incidence of AEs is highest for γ-secretase inhibitor versus placebo (OR 0.16, 95%CI 0.02-1.55), while TKI is associated with the least AEs (OR 0.62, 95%CI 0.06-6.97). γ-secretase inhibitor provides superior local control of tumors, while chemotherapy and TKI may offer better long-term survival benefits. Among the three regimens, TKI demonstrated better treatment-related safety. These findings have important implications for guiding clinical practice in systemic treatment of DT.

CD38 as theranostic target in oncology.

CD38 is a multifunctional transmembrane glycoprotein found in multiple tissues and overexpressed in many cancer cells, notably in hematological malignancies such as leukemia and multiple myeloma (MM). Therefore, targeting CD38 remains an attractive strategy for cancer treatment in hematological malignancies as well as in solid tumors. It plays a critical role in the progression of these diseases through its ADP-ribosyl cyclase and cADPR-hydrolase activities. Its importance has led to the development of various anti-CD38 monoclonal antibodies (mAbs), including daratumumab and isatuximab, approved for MM treatment. These mAbs exert their anti-tumor effects through Fc-dependent immune mechanisms and immunomodulation, enhancing T-cell and NK-cell-mediated responses. However, resistance mechanisms arise during the treatment with daratumumab, creating the necessity for new therapies. This review explains current knowledge about the role of CD38 as a target in oncology and aims to delineate the use of single domain antibodies (sdAbs) as innovative theranostic tools in nuclear medicine. For diagnostic purposes, PET radionuclides like 68Ga, 64Cu, and SPECT radionuclides like 99mTc and 111In, are commonly used. Significant progress has been made in anti-CD38 radioligand therapy (RLT), with anti-CD38 antibodies providing insights into tumor biology and treatment efficacy. In terms of therapy, RLT is a promising approach that offers precise targeting of malignant cells while minimizing exposure to healthy tissue. This involves the use of radionuclides emitting α particles, like 225Ac, 212Pb or 211At, and β--particles like 90Y, 131I, or 177Lu, to exert cytotoxic effects. Derived from Camelidae heavy chain antibodies, sdAbs offer advantages over conventional mAbs such as small size, high stability, specificity, and ability to recognize hidden epitopes. CD38-specific sdAbs, such as sdAb 2F8, characterized by our laboratory, showing excellent tumor targeting and their engineered constructs, such as biparatopic antibodies and chimeric antibodies, represent a new generation of theranostic agents for diagnosis and treatment CD38-expressing malignancies.

Definition and Predictors of Early Recurrence in Neoadjuvantly Treated Esophageal and Gastroesophageal Adenocarcinoma: a Dual-Center Retrospective Cohort Study.

BACKGROUND: Early recurrence after esophagectomy is often used as a surrogate for aggressive tumor biology and treatment failure. However, there is no standardized definition of early recurrence, and predictors for early recurrence are unknown. Therefore, we aimed to define an evidence-based cutoff to discriminate early and late recurrence and assess the influence of neoadjuvant treatment modalities for patients with esophageal or gastroesophageal-junction adenocarcinoma (EAC). This dual-center retrospective cohort study included patients who underwent esophagectomy for stage II-III EAC after neoadjuvant treatment with chemotherapy using 5-fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) or radiochemotherapy according to the Chemoradiotherapy for Esophageal Cancer followed by Surgery Study (CROSS)protocol from 2012 to 2022. The optimal cutoff for early versus late recurrence was calculated by using the most significant difference in survival after recurrence (SAR). Multivariable logistic regression was used to identify variables associated with early recurrence. Of 334 included patients, 160 (47.9%) were diagnosed with recurrence. Most patients had systemic (60.5%) or multiple sites of recurrence (21.1%), whereas local-only recurrence (9.2%) and carcinomatosis (9.2%) were rare. The optimal interval between surgery and recurrence for distinguishing early and late recurrence was 18 months (median SAR: 9.1 versus 17.8 months, p = 0.039) with only 24% of recurrences diagnosed after the calculated cutoff. Advanced pathologic tumor infiltration (ypT3-4, p = 0.006), nodal positivity (p = 0.013), poor treatment response (>10% residual tumor, p = 0.015), and no adjuvant treatment (p = 0.048) predicted early recurrence. Early recurrence can be defined as recurrent disease within 18 months. Hallmarks for early recurrence are poor response to neoadjuvant therapy with persisting advanced disease. In those patients, adjuvant therapy and closer follow-up should be considered.

CITMIC: Comprehensive Estimation of Cell Infiltration in Tumor Microenvironment based on Individualized Intercellular Crosstalk.

The tumor microenvironment (TME) cells interact with each other and play a pivotal role in tumor progression and treatment response. A comprehensive characterization of cell and intercellular crosstalk in the TME is essential for understanding tumor biology and developing effective therapies. However, current cell infiltration analysis methods only partially describe the TME's cellular landscape and overlook cell-cell crosstalk. Here, this approach, CITMIC, can infer the cell infiltration of TME by simultaneously measuring 86 different cell types, constructing an individualized cell-cell crosstalk network based on functional similarities between cells, and using only gene transcription data. This is a novel approach to estimating the relative cell infiltration levels, which are shown to be superior to the current methods. The TME cell-based features generated by analyzing melanoma data are effective in predicting prognosis and treatment response. Interestingly, these features are found to be particularly effective in assessing the prognosis of high-stage patients, and this method is applied to multiple high-stage adenocarcinomas, where more significant prognostic performance is also observed. In conclusion, CITMIC offers a more comprehensive description of TME cell composition by considering cell-cell crosstalk, providing an important reference for the discovery of predictive biomarkers and the development of new therapeutic strategies.

Recent Advances in Nanomaterial-Mediated Cell Death for Cancer Therapy.

Nanomedicine has shown great anticancer potential by disrupting redox homeostasis and increasing the levels of oxidative stress, but the therapeutic effect is limited by factors including the intrinsic self-protection mechanism of tumors. Cancer cell death can be induced by the exploration of different cell death mechanisms, such as apoptosis, pyroptosis, necroptosis, cuproptosis, and ferroptosis. The merging of nanotechnology with biomedicine has provided tremendous opportunities to construct cell death-based nanomedicine for innovative cancer therapy. Nanocarriers are not only used for the targeted delivery of cell death inducers, but also as therapeutic components to induce cell death to achieve efficient tumor treatment. This review focuses on seven cell death modalities mediated by nanomaterials, such as apoptosis, pyroptosis, necroptosis, ferroptosis, cuprotosis, immunogenic cell death, and autophagy. The mechanisms of these seven cell death modalities are described in detail, as well as the preparation of nanomaterials that induce them and the mechanisms, they used to exert their effects. Finally, this work describes the potential future development based on the current knowledge related to cell death induced by nanomaterials.

Challenges and advances of immune checkpoint therapy

AbstractBackground and ObjectivesImmuno‐checkpoint therapy (ICT) significantly alters the clinical course of cancer patients, providing long‐lasting clinical benefits and offering the potential for cure to some patients. However, response rates for different tumour types vary, and predictive biomarkers are needed to enhance patient selection for the purpose of optimising effectiveness and reducing toxicity. This has driven efforts to decipher the immune and non‐immune factors that regulate ICT response.Main ContentThis review offers a thorough examination of the advantages and future challenges of immune checkpoint inhibitors in cancer therapy. Additionally, we explore ongoing efforts to address current challenges, such as guiding subsequent clinical trials, developing ICT combination therapy strategies and utilising epigenetics to enhance clinical efficacy.Conclusion and PerspectivesDespite significant progress, ICT faces challenges including immune‐related adverse events (irAEs) and resistance mechanisms. Ongoing research focuses on developing novel biomarkers, combination therapies, and epigenetic strategies to improve the efficacy and safety of ICT for cancer patients worldwide. Future studies are required to validate these findings across different tumor types and treatment settings.

Living Therapeutics for Synergistic Hydrogen-Photothermal Cancer Treatment by Photosynthetic Bacteria.

Hydrogen gas (H2) therapy, recognized for its inherent biosafety, holds significant promise as an anti-cancer strategy. However, the efficacy of H2 treatment modalities is compromised by their reliance on systemic gas administration or chemical reactions generation, which suffers from low efficiency, poor targeting, and suboptimal utilization. In this study, living therapeutics are employed using photosynthetic bacteria Rhodobacter sphaeroides for in situ H2 production combined with near-infrared (NIR) mediated photothermal therapy. Living R. sphaeroides exhibits strong absorption in the NIR spectrum, effectively converting light energy into thermal energy while concurrently generating H2. This dual functionality facilitates the targeted induction of tumor cell death and substantially reduces collateral damage to adjacent normal tissues. The findings reveal that integrating hydrogen therapy with photothermal effects, mediated through photosynthetic bacteria, provides a robust, dual-modality approach that enhances the overall efficacy of tumor treatments. This living therapeutic strategy not only leverages the therapeutic potential of both hydrogen and photothermal therapeutic modalities but also protects healthy tissues, marking a significant advancement in cancer therapy techniques.

Cordycepin Enhances the Anticancer Efficacy of PD-L1 Blockade by Modulating the Tumor Microenvironment of Colon Cancer

BackgroundPD-L1 blockade has been found to be effective in treating multiple malignancies. Combined therapy is proposed to provide better therapeutic effects. Cordycepin, a prominent bioactive compound found in cordyceps, can inhibit the development of various cancers. PurposeThis study aimed to determine the efficacy of combined anti-PD-L1 antibody and cordycepin in tumor treatment. MethodsA single-cell RNA sequencing was used to analyze the mechanism of combined treatment. ResultsCombination therapy of anti-PD-L1 and cordycepin significantly inhibited tumor growth by regulating the T cell ratio and improving the function of CD8+T cells. Furthermore, cordycepin promoted the reprogramming of type-II macrophages into type-I macrophages, a process confirmed through flow cytometry analysis of the underlying mechanism. ConclusionOur findings demonstrate that the combination of anti-PD-L1 and cordycepin effectively suppressed tumor growth by regulating the proportion of T cells and reprograming type-II macrophages.

Evaluating the Impact of Adjunctive Partial Cryoablation on Dual Checkpoint Inhibitor Immunotherapy Response in a Murine Model.

Purpose To evaluate the impact of adjunctive partial cryoablation on checkpoint inhibitor (CPI) immunotherapy response. Materials and Methods One hundred fifty-six mice (equal number of male and female animals) with dual-implanted tumor models were treated with dual CPI or a vehicle and randomized to treatment of a single tumor with partial cryoablation. Tumors were followed for 60 days following cryoablation for response assessment. In additional groups, the tumor microenvironment was characterized via flow cytometry, cytokine analysis, and immunohistochemistry. Statistical comparison was made between the different treatment groups regarding T-cell infiltration and activation characteristics within the noncryoablated tumor and cytokine levels within the partially ablated tumor. Additionally, qualitative assessment of T-cell activation within the cryoablated and noncryoablated tumors at immunofluorescence was carried out. Results At 60 days following treatment, CPI and adjunctive cryoablation-treated MC-38 mice had a significantly increased survival rate (79%) compared with mice treated with CPI alone (61%; P < .001). CT-26 mice also had an increased survival rate (57% vs 35%, respectively; P = .04). Following cryoablation, increases in inflammatory cytokines and chemokines within the treated tumors were observed. Flow cytometry of noncryoablated tumor showed increased CD8 T-cell activation. Immunofluorescence and histologic evaluation following cryoablation further demonstrated a robust CD8 T-cell and myeloid infiltrate. Conclusion Adjunctive cryoablation significantly increased the response to dual CPI in multiple cancer models at both partially ablated and distant (nonablated) tumor sites. Immune analysis suggests cryoablation promotes a vigorous immune response within the partially cryoablated tumor that increases activation of the adaptive immune system within distant tumor sites.

The Landscape of microRNAs in Bone Tumor: A Comprehensive Review in Recent Studies.

Cancer, the second greatest cause of mortality worldwide, frequently causes bone me-tastases in patients with advanced-stage carcinomas such as prostate, breast, and lung cancer. The existence of these metastases contributes to the occurrence of skeletal-related events (SREs), which are defined by excessive pain, pathological fractures, hypercalcemia, and spinal cord com-pression. These injurious incidents leave uncomfortably large holes in each of the cancer patient's life quality. Primary bone cancers, including osteosarcoma (OS), chondrosarcoma (CS), and Ewing's sarcoma (ES), have unclear origins. MicroRNA (miRNA) expression patterns have been changed in primary bone cancers such as OS, CS, and ES, indicating a role in tumor development, invasion, metastasis, and treatment response. These miRNAs are persistent in circulation and ex-hibit distinct patterns in many forms of bone tumors, making them potential biomarkers for early detection and treatment of such diseases. Given their crucial regulatory functions in various bio-logical processes and conditions, including cancer, this study aims to look at miRNAs' activities and possible contributions to bone malignancies, focusing on OS, CS, and ES. In conclusion, miRNAs are valuable tools for diagnosing, monitoring, and predicting OS, CS, and ES outcomes. Further research is required to fully comprehend the intricate involvement of miRNAs in these bone cancers and to develop effective miRNA-based treatments.

Natural diterpene carrier-free hydrogel enhances antigen presentation and intensifies T cell activation for tumor immunotherapy

Although immunotherapy has revolutionized cancer treatment, the low immunogenicity, insufficient T cells intratumoral infiltration and defective antigen presentation in the “cold” tumor microenvironment limit its clinical application. To address this challenge, enlightened by the clinical combined application of antitumor herb medicines, we developed a carrier-free hydrogel KEEM by integrating multiple natural active lipophilic components with manganese ions into a natural co-assembled ternary system. The KEEM hydrogel induced the formation of hydroxyl radicals by Fenton-like reactions, leading to apoptosis, while simultaneously inducing tumor cell ferroptosis through the system xc−-GSH-GPX4 axis. Subsequent release of damage-associated molecular patterns (DAMPs) proved the emergence of immunogenic cell death (ICD). Additionally, manganese ions could directly activate the cGAS-STING pathway, further amplifying the immunostimulatory effects. This synergistic effect promoted dendritic cell maturation thus enhancing antigen presentation, and mediating the change of tumor microenvironment (TME) from “cold” to “hot”. In hepatoma ascites and melanoma models, KEEM combined with immune checkpoint blockade and adoptive T cell therapy respectively demonstrated promising anti-tumor effects in vivo, meanwhile showing excellent biocompatibility and biosafety. Thus, the combination of this multi-diterpenoids carrier-free hydrogel with immunotherapy offers a new strategy for clinical immune-refractory tumor treatment.

CaCO3-encircled hollow CuS nanovehicles to suppress cervical cancer through enhanced calcium overload-triggered mitochondria damage

Cervical cancer stands is a formidable malignancy that poses a significant threat to women's health. Calcium overload, a minimally invasive tumor treatment, aims to accumulate an excessive concentration of Ca2+ within mitochondria, triggering apoptosis. Copper sulfide (CuS) represents a photothermal mediator for tumor hyperthermia. However, relying solely on thermotherapy often proves insufficient in controlling tumor growth. Curcumin (CUR), an herbal compound with anti-cancer properties, inhibits the efflux of exogenous Ca2+ while promoting its excretion from the endoplasmic reticulum into the cytoplasm. To harness these therapeutic modalities, we have developed a nanoplatform that incorporates hollow CuS nanoparticles (NPs) adorned with multiple CaCO3 particles and internally loaded with CUR. This nanocomposite exhibits high uptake and easy escape from lysosomes, along with the degradation of surrounding CaCO3, provoking the generation of abundant exogenous Ca2+in situ, ultimately damaging the mitochondria of diseased cells. Impressively, under laser excitation, the CuS NPs demonstrate a photothermal effect that accelerates the degradation of CaCO3, synergistically enhancing the antitumor effect through photothermal therapy. Additionally, fluorescence imaging reveals the distribution of these nanovehicles in vivo, indicating their effective accumulation at the tumor site. This nanoplatform shows promising outcomes for tumor-targeting and the effective treatment in a murine model of cervical cancer, achieved through cascade enhancement of calcium overload-based dual therapy.

Self-assembled aldehyde dehydrogenase-activatable nano-prodrug for cancer stem cell-enriched tumor detection and treatment

Cancer stem cells, characterized by high tumorigenicity and drug-resistance, are often responsible for tumor progression and metastasis. Aldehyde dehydrogenases, often overexpressed in cancer stem cells enriched tumors, present a potential target for specific anti-cancer stem cells treatment. In this study, we report a self-assembled nano-prodrug composed of aldehyde dehydrogenases activatable photosensitizer and disulfide-linked all-trans retinoic acid for diagnosis and targeted treatment of cancer stem cells enriched tumors. The disulfide-linked all-trans retinoic acid can load with photosensitizer and self-assemble into a stable nano-prodrug, which can be disassembled into all-trans retinoic acid and photosensitizer in cancer stem cells by high level of glutathione. As for the released photosensitizer, overexpressed aldehyde dehydrogenase catalyzes the oxidation of aldehydes to carboxyl under cancer stem cells enriched microenvironment, activating the generation of reactive oxygen species and fluorescence emission. This generation of reactive oxygen species leads to direct killing of cancer stem cells and is accompanied by a noticeable fluorescence enhancement for real-time monitoring of the cancer stem cells enriched microenvironment. Moreover, the released all-trans retinoic acid, as a differentiation agent, reduce the cancer stem cells stemness and improve the cancer stem cells enriched microenvironment, offering a synergistic effect for enhanced anti-cancer stem cells treatment of photosensitizer in inhibition of in vivo tumor growth and metastasis.

Self-supply of hydrogen peroxide by a bimetal-based nanocatalytic platform to enhance chemodynamic therapy for tumor treatment.

The Tumor Microenvironment (TME) is characterized by low pH, hypoxia, and overexpression of glutathione (GSH). Owing to the complexity of tumor pathogenesis and the heterogeneity of the TME, achieving satisfactory efficacy with a single treatment method is difficult, which significantly impedes tumor treatment. In this study, composite nanoparticles of calcium-copper/alginate-hyaluronic acid (CaO2-CuO2@SA/HA NC) with pH and GSH responsiveness were prepared for the first time through a one-step synthesis using hyaluronic acid (HA) as a targeting ligand. Nanoparticles loaded with H2O2 can enhance the ChemoDynamic Therapy (CDT) effects. Simultaneously, Cu2+ can generate oxygen in the TME and alleviate hypoxia in tumor tissue. Cu2+ and H2O2 undergo the Fenton reaction to produce cytotoxic hydroxyl radicals and Ca2+ ions, which enhance the localization and clearance of nanoparticles in tumor cells. Additionally, HA and sodium alginate (SA) were utilized to improve the targeting and biocompatibility of the nanoparticles. FTIR, XRD, DLS, SEM, TEM, and other analytical methods were used to investigate their physical and chemical properties. The results indicate that the CaO2-CuO2@SA/HA NC prepared using a one-step method had a particle size of 220 nm, a narrow particle size distribution, and a uniform morphology. The hydrogen peroxide self-supplied nanodrug delivery system exhibited excellent pH-responsive release performance and glutathione-responsive •OH release ability while also reducing the level of reactive oxide species (ROS) quenching. In vitro cell experiments, no obvious side effects on normal tissues were observed; however, the inhibition rate of malignant tumors HepG2 and DU145 exceeded 50%. The preparation of CaO2-CuO2@SA/HA NC nanoparticles, which can achieve both chemokinetic therapy and ion interference therapy, has demonstrated significant potential for clinical applications in cancer therapy.
