D2 surgery followed by adjuvant chemotherapy has been established as the standard of care for patients with locally advanced gastric cancer in Asian countries. However, its efficacy is still unsatisfactory, especially for pathological N3 disease. The RACING trial is a randomized, multicenter, Phase III trial designed to compare the efficacy and safety of chemotherapy alone versus chemotherapy in combination with PD-1 inhibitor and radiotherapy in patients with pN3 gastric or gastroesophageal junction adenocarcinoma. A total of 433 patients will be assigned at a 1:1 ratio to the two arms. The primary end point is the 3-year disease-free survival rate. The secondary end points include the 3-year overall survival rate, 3-year local recurrence-free survival rate, treatment-related adverse events and quality of life.Clinical Trial Registration: NCT04997837 (ClinicalTrials.gov).

Prostate cancer (PCa) has become a common disease among middle-aged and elderly men. The lipoxygenase (LOX) pathway plays a crucial role in the occurrence, development, invasion and metastasis of PCa and is therefore considered a new target for the prevention and treatment of PCa. 5-LOX and 12-LOX have a promoting effect on the occurrence, development, invasion and metastasis of PCa. 15-LOX-2 has an inhibitory effect on PCa. LOX inhibitors can effectively inhibit the metabolic activity of LOX. The research aims to review the mechanism of action and inhibitors of LOX in PCa, in order to provide relevant references for the prevention and treatment of PCa.

What is this summary about?: This is a summary of a phase 2 clinical study called DeLLphi-301. The study looked at how effective and safe a medicine called tarlatamab was in participants with small cell lung cancer (SCLC). Participants previously received at least two other treatments for their SCLC. Tarlatamab is a new medicine that locates a protein called DLL3 on the cancer, which allows T cells to attack the cancer. T cells belong to the body's natural defense system known as the immune system. The DeLLphi-301 study separated participants into two groups to receive tarlatamab 10 mg or 100 mg to determine which dose best shrank SCLC with minimal side effects. All participants received a small first dose (1 mg tarlatamab) to decrease the risk of an immune system reaction called cytokine release syndrome (CRS). Tarlatamab was given through the participant's vein once every 2 weeks. This method of administration is known as intravenous (IV) infusion.

What were the results of the dellphi-301 study?: In the group given 10 mg tarlatamab, 40% of participants responded to treatment (cancer shrank). In the group given 100 mg tarlatamab, 32% of participants responded to treatment (cancer shrank). After taking tarlatamab at either dose, 59% of participants lived for at least 6 months without their cancer growing or getting worse.The most common side effect was CRS, which occurred in 51% of participants in the group given 10 mg tarlatamab and 61% of participants in the group given 100 mg tarlatamab. Other common side effects were decreased appetite, fever, constipation, and anemia. Some participants had a type of immune reaction called immune effector cell-associated neurotoxicity syndrome (ICANS). A small number of participants (3%) stopped taking tarlatamab because of side effects related to tarlatamab.

What do the results from the dellphi-301 study mean?: The study found that tarlatamab given every 2 weeks shrank SCLC in participants with SCLC who received previous treatments. Participants given the 10 mg tarlatamab dose had fewer side effects than those given the 100 mg tarlatamab dose.Clinical Trial Registration: NCT05740566 (DeLLphi-304) (ClinicalTrials.gov).

Aim: To investigate the prognostic value of inflammatory markers in esophageal squamous cell carcinoma (ESCC) patients treated with immune checkpoint inhibitors (ICIs).Materials & methods: The infiltration of CD3⁺ and CD8⁺ T cells in tissue microarrays from 180 patients who underwent radical esophagectomy was detected using immunohistochemistry. A separate cohort of 351 patients with metastatic/recurrent or unresectable ESCC treated with ICIs was enrolled for further investigation. The overall survival difference among groups was assessed using Kaplan-Meier analysis. Cox proportional hazards models were employed to investigate the prognostic impact of the inflammatory markers, along with other factors.Results: Decreased inflammation was found to be associated with increased CD3⁺ and CD8⁺ T-cell infiltration and a better prognosis. Then, the value of inflammatory markers in predicting survival in 351 ESCC patients receiving immunotherapy was validated. Ultimately, the systemic immune-inflammation index was identified as an independent prognostic factor for overall survival. Additionally, the patients with no distant organ metastasis, or treated by first-line immunotherapy combined with concurrent chemoradiotherapy can considerably prolong survival.Conclusion: Inflammation is associated with the level of tumor infiltrating lymphocytes and that the systemic immune-inflammation index is an effective prognostic predictor for ESCC patients treated with ICIs.

What is this summary about?: This article provides a plain-language summary of the results of a clinical trial called the LOTIS-2 study.The LOTIS-2 study included 145 participants with an aggressive type (one that forms, grows, or spreads quickly) of non-Hodgkin lymphoma called diffuse large B-cell lymphoma (a type of blood cancer), or DLBCL for short, whose disease came back or did not respond after 2 or more previous treatments. The LOTIS-2 study was conducted from August 2018 to September 2022.Participants received loncastuximab tesirine, also referred to as Lonca, for up to 1 year, or longer if the treatment was working, and their health was monitored. The primary purpose of the LOTIS-2 study was to find out if participants' lymphoma shrank partially or completely after receiving Lonca.

What were the results?: A total of 145 participants who were treated with Lonca lived a median (meaning the middle value in a set of numbers) of 9.5 months after starting Lonca treatment. The lymphoma shrank partially or completely in nearly half of participants and shrank completely in 1 in 4 participants. Among participants whose disease either shrank partially or completely in response to Lonca treatment, responses happened relatively quickly, with a median time to response (the time between starting treatment and when the participant's lymphoma either partially or completely shrank) of 41 days. In these participants, the lymphoma did not grow or come back for a median of 13.4 months. Researchers estimated that 83% of participants whose disease shrank completely remained disease free for at least 1 year.Nearly all participants had a side effect from Lonca treatment. The most common side effects were abnormal liver tests (increased gamma-glutamyl transferase), decreased white blood cells (neutropenia), and decreased platelets (thrombocytopenia). One in 4 participants had their treatment stopped due to side effects. The most common side effects that resulted in participants needing to stop Lonca treatment were abnormal liver tests (increased gamma-glutamyl transferase), swelling in the arms or legs (peripheral edema), swelling in an individual spot (localized edema), and fluid around the lungs (pleural effusion).

What do the results of the study mean?: These results show that Lonca is a treatment option with controllable side effects for many patients with DLBCL whose disease did not respond or came back after 2 or more previous treatments. For participants whose lymphoma completely shrank while taking Lonca, those responses to treatment occurred quickly and lasted for over a year.

Aim: Trifluridine/tipiracil-bevacizumab is a standard of care in metastatic colorectal cancer (mCRC) after chemotherapy failure. We aim to assess the addition of XB2001 (anti-IL-1 alpha monoclonal antibody) plus trifluridine/tipiracil-bevacizumab in mCRC refractory to standard chemotherapy.Methods: This multicenter, randomized, double blind, non-comparative Phase I-II study (ClinicalTrials.gov NCT05201352) will assess the efficacy and safety of trifluridine/tipiracil-bevacizumab and XB2001 in patients with mCRC previously treated for metastatic disease by chemotherapy treatment including oxaliplatin, irinotecan, 5-FU, antiangiogenic and/or anti-EGFR if indicated. Primary end point of Phase I is the safety according to the Maximum Tolerated Dose (MTD) of XB2001. Primary end point of Phase II is the efficacy of trifluridine/tipiracil-bevacizumab + XB2001 in term of 6-month overall survival. Ancillary analysis will be performed.

Health literacy is essential in cancer care. Low health literacy compromises the capacity to maintain one's health through self-management and collaboration with healthcare providers, especially when facing cognitive side effects related to cancer and its treatments. Cancer-related cognitive impairment (CRCI) is a common phenomenon among cancer patients and might determine a significant impact on their quality of life, yet it is still under identified by both clinicians and patients. This perspective aims to discuss the implications of patients' and healthcare professionals' lack of awareness on the matter and argues about the importance of improving the level of information on CRCI to mitigate difficulties in identifying and managing such manifestations on various levels.

A cyclin-dependent kinase 4/6 (CDK4/6) inhibitor combined with endocrine therapy is the standard-of-care for patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative advanced breast cancer. However, not all patients respond to the treatment, resistance often occurs and efficacy outcomes from early breast cancer trials have been mixed. To identify biomarkers associated with CDK4/6 inhibitor response or resistance, we combined bioinformatic-database analyses, artificial intelligence-assisted literature review, and manual literature review (Embase and OVID Medline; search window: January 2012-October 2022) to compile data to comprehensively describe the CDK4/6 inhibitor biomarker landscape. Based on these results, and validation by external experts, we identified 15 biomarkers of clinical importance (AR , AURKA, ERBB2, ESR1, CCNE1, CDKN1A/B, CDK2, CDK6, CDK7, CDK9, FGFR1/2, MYC, PIK3CA/AKT, RB1 and STAT3) that could guide future breast cancer research.

Medulloblastoma (MB) is the most frequent malignant brain tumor in children. MB originates from neural precursor cells in distinctive regions of the rhombic lip and their maturation occurs in the cerebellum or the brain stem during embryonal development. Autophagy is also referred to as self-eating' which is a catabolic process that often triggers cellular homeostasis through the salvaging of degenerated proteins as well as organelles. Autophagy influence cell survival via aberrant proteins that could accumulate within the cell and influence potential signaling and transport mechanisms. The role of autophagy in MB aggressiveness as well as tumorigenesis is a very complex process. This review targets specifically data reporting the key roles of autophagy in the pathogenesis and therapy of MB.

Aim: We report clinical activity and safety of sitravatinib in patients with advanced cancer from basket cohorts with specific molecular alterations, in a Phase Ib study.Materials & methods: Patients with advanced solid tumors harboring amplification, mutation, or rearrangement of MET, AXL, RET, NTRK, DDR2, KDR, PDGFRA, KIT or CBL received sitravatinib once daily. Primary end point was confirmed objective response rate (ORR).Results: In total, 113 patients were enrolled following a median of 3 (range 1-18) prior systemic regimens. Altered RET (n = 31), CBL (n = 31) and MET (n = 17) were most frequent cohorts. Overall, 68.9% had reduced tumor volume and most (61.5%) had a best objective response of stable disease. ORR was highest in patients with RET-rearranged non-small cell lung cancer (21.1%) but did not differ significantly from the null hypothesis (ORR ≤15%; p = 0.316). Median progression-free survival and overall survival (5.7 and 24.2 months, respectively) were also longest in the RET-rearranged non-small cell lung cancer cohort. Diarrhea (61.1%), fatigue (50.4%) and hypertension (46.9%) were the most frequent treatment-emergent adverse events. Most treatment-emergent adverse events were mild-to-moderate in severity. The study closed before the planned number of patients were enrolled in all cohorts.Conclusion: Sitravatinib had a manageable safety profile with modest signals of clinical activity in patients with molecularly selected solid tumors.Clinical trial registration: www.clinicaltrials.gov identifier is NCT02219711.
