A novel mouse model recapitulating the MMR-defective SCLC subtype uncovers an actionable sensitivity to immune checkpoint blockade
Small cell lung cancer (SCLC) has an extremely poor prognosis. Despite high initial response rates to chemotherapy and modest survival improvements with the addition of immune checkpoint inhibitors (ICI), almost all patients experience relapse and fatal outcomes. Recent genomic insights uncovered extensive molecular heterogeneity in addition to the almost uniform loss of RB1 and TRP53. Additionally, defective DNA mismatch repair (MMR) has recently been described in some SCLC cases. Here, we generated a novel SCLC mouse model capturing MMR deficiency and assessed immunotherapy responses.
The role of gut microbial β-glucuronidases in carcinogenesis and cancer treatment: a scoping review
The human gut microbiota influence critical functions including the metabolism of nutrients, xenobiotics, and drugs. Gut microbial β-glucuronidases (GUS) enzymes facilitate the removal of glucuronic acid from various compounds, potentially affecting anti-cancer drug efficacy and reactivating carcinogens. This review aims to comprehensively analyze and summarize studies on the role of gut microbial GUS in cancer and its interaction with anti-cancer treatments. Its goal is to collate and present insights that are directly relevant to patient care and treatment strategies in oncology.

Natural compounds modulate the mechanism of action of tumour-associated macrophages against colorectal cancer: a review
Colorectal cancer (CRC) exhibits a substantial morbidity and mortality rate, with its aetiology and pathogenesis remain elusive. It holds significant importance within the tumour microenvironment (TME) and exerts a crucial regulatory influence on tumorigenesis, progression, and metastasis. TAMs possess the capability to foster CRC pathogenesis, proliferation, invasion, and metastasis, as well as angiogenesis, immune evasion, and tumour resistance. Furthermore, TAMs can mediate the prognosis of CRC. In this paper, we review the mechanisms by which natural compounds target TAMs to exert anti-CRC effects from the perspective of the promotional effects of TAMs on CRC, mainly regulating the polarization of TAMs, reducing the infiltration and recruitment of TAMs, enhancing the phagocytosis of macrophages, and regulating the signalling pathways and cytokines, and discuss the potential value and therapeutic strategies of natural compounds-targeting the TAMs pathway in CRC clinical treatment.

Inhibition of NPC1 suppresses cell proliferation and β-catenin signaling activation of liver cancer
Niemann-Pick Type C1 (NPC1) plays a significant role in the development of liver diseases and liver cancer. Our objective was to investigate the involvement of NPC1 in regulating liver cancer development. We observed that high levels of NPC1 expression in tumor tissues from patients with liver cancer were associated with a poor prognosis. Through in vitro experiments, we found that inhibiting NPC1 expression reduced the proliferation, invasion, and migration of liver cancer cells, while also inducing apoptosis in these cells. Additionally, the inhibition of NPC1 led to decreased activation of Wnt/β-catenin signaling. In vivo studies further supported our findings by demonstrating that the suppression of liver cancer cell growth was effectively achieved through the inhibition of NPC1. Overall, our results strongly indicate that the inhibition of NPC1 suppresses liver cancer cell proliferation. Targeting NPC1 is a promising potential therapeutic strategy for liver cancer.
Bioinformatic and experimental data pertaining to the role of the NLRP3 inflammasome in ovarian cancer
The Nod-Like Receptor (NLR) family pyrin domain containing 3 (NLRP3) inflammasome plays a role in regulating inflammatory signaling and is a well-established contributor to pyroptotic cell death. It has been investigated extensively in cancer but there remains limited evidence of its role within ovarian cancer (OC). Bioinformatic investigation of gene expression data has highlighted that higher expression of NLRP3 and genes associated with the NLRP3 complex appear to be positively correlated with OC and may also have prognostic significance. However, heterogeneity exists within the results and experimental data is limited and contradictory. If the NLRP3 inflammasome is to be exploited as a therapeutic target, further laboratory-based investigation is required to determine its role in cancer. Furthermore, its relationship with clinically important characteristics such as histopathological subtype may be of key significance in developing targeted therapies towards specific cohorts of patients.
Opportunities and challenges of using circulating tumor DNA to predict lung cancer immunotherapy efficacy
Immune checkpoint inhibitors (ICIs), particularly anti-programmed death 1 (PD-1)/ programmed death ligand 1 (PD-L1) antibodies, have led to significant progress in lung cancer treatment. However, only a minority of patients have responses to these therapies. Detecting peripheral blood of circulating tumor DNA (ctDNA) allows minimally invasive diagnosis, characterization, and monitoring of lung cancer. ctDNA has potential to be a prognostic biomarker and a predictor of the response to ICI therapy since it can indicate the genomic status and tumor burden. Recent studies on lung cancer have shown that pretreatment ctDNA analysis can detect residual proliferative disease in the adjuvant immunotherapy setting and evaluate tumor burden in patients with metastatic disease. Early ctDNA dynamics can not only predict the clinical outcome of ICI therapy but also help distinguish between pseudoprogression and real progression. Furthermore, in addition to quantitative assessment, ctDNA can also detect genetic predictors of response to ICI therapy. However, barriers still exist in the application of ctDNA analysis in clinical lung cancer treatment. The predictive value of ctDNA in lung cancer immunotherapy requires further identification and resolution of these challenges. This review aims to summarize the existing data of ctDNA analysis in patients receiving immunotherapy for lung cancer, understand the limitations of clinical treatment, and discuss future research directions.

Efficacy of sintilimab combined with neoadjuvant chemotherapy and trastuzumab in conversional treatment of locally advanced HER2-positive gastric cancer: case analysis and literature review
Regional lymph nodes that are fixed and fused into clusters or those exhibiting metastases outside the regional lymph nodes are generally classified as stage IV (M1) or unresectable. Patients with such nodes almost always need pre-operative treatment so that they can undergo surgical resection. Combining immunotherapy with trastuzumab and chemotherapy significantly improved the prognosis of HER-2 positive gastric/gastroesophageal junction (G/GEJ) cancer. However, very few reports are available on the role of immunotherapy in converting patients with unresectable cancer to resectable cancer.
