Colonoscopy is the gold standard for the diagnosis and resection of preneoplastic lesions, allowing the prevention of colon cancer. A colonoscopy is more efficient with proper preparation of the colon, as it allows for a higher rate of adenoma detection and cecal intubation. In routine practice, up to 30% of colonoscopies are poorly prepared and 11% of patients do not show up for their appointment. Adenomas not visualized in the initial colonoscopy due to poor preparation reached 68% and the rate of undetected cancers was 66.7%. A proper colon cleanse is conditioned by different factors; among them, failure to comply with the diet and take laxatives poses 5 times the risk of having a deficient colon preparation. The purpose of our study is the design and implementation of an app that facilitates the preparation of colonoscopy and evaluates its impact on compliance with diet and laxative intake.

This prospective, randomized phase II trial is designed to evaluate whether low-dose short-course radiotherapy differs from common-dose short-course radiotherapy in terms of efficacy when both regimens are sequentially combined with CAPOX, a PD-1 monoclonal antibody, and interleukin-2 (IL-2) in patients with locally advanced rectal cancer. The study is based on findings from our previous single-center, single-arm PRIDE01 study, in which neoadjuvant short-course radiotherapy followed by systemic chemoimmunotherapy and IL-2 demonstrated encouraging antitumor activity relative to historical short-course radiotherapy-based approaches. The current trial aims to provide more robust clinical evidence regarding the potential role of low-dose radiotherapy combined with IL-2 as a sensitization strategy in multimodal neoadjuvant therapy. By comparing complete response rates between the two radiotherapy dose levels, this study may help define an optimized neoadjuvant approach and support future organ-preservation strategies for patients with locally advanced rectal cancer.

This research study is designed for patients with extensive-stage small cell lung cancer (ES-SCLC) who have already received four cycles of standard chemotherapy, with at least two cycles combined with immunotherapy, and have achieved disease control (stable disease, partial response, or complete response) at their last efficacy evaluation.
In this study, participants will be randomly assigned to one of two groups:
Group A will receive standard immunotherapy plus 1 to 3 courses of allogeneic natural killer (NK) cell therapy. Each course consists of six NK cell infusions given over 28 days.
Group B will receive standard immunotherapy alone. All participants will continue treatment until their disease progresses or they experience unacceptable side effects. The immunotherapy agents used in this study are those recommended by major international and national clinical guidelines for extensive-stage SCLC, including but not limited to durvalumab, atezolizumab, serplulimab, and adebrelimab.
The purpose of this study is to evaluate whether adding NK cell therapy to standard immunotherapy can provide additional benefits for patients with extensive-stage SCLC who have responded well to initial treatment.

The primary treatment option for non-small cell lung cancer (NSCLC) adenocarcinoma (ADC) with activating epidermal growth factor receptor (EGFR) mutation is EGFR tyrosine kinase inhibitor (TKI). After a certain period of treatment with EGFR TKI, acquired resistance emerges most frequently with a secondary mutation, p.T790M (36-50%), followed by MET amplification (10-19%). Interestingly, up to 3-5% of patients experience histological transformation into small cell lung cancer (SCLC).
As an underlying mechanism, ADC with a predisposed clonally inactivated Rb and p53 mutation and APOBEC mutation signature is known to be associated with SCLC transformation. The transformed SCLC harbors similar morphological and immunohistochemical (IHC) characteristics as those observed in de novo SCLC, including high expression of chromogranin and synaptophysin. However, little is known about the clinical outcomes of transformed SCLC, with limited studies arguing that their outcomes are similar to those of de novo SCLC, where the median overall survival is approximately 9 to 10 months after the transformation.
As the first line treatment of SCLC, atezolizumab or durvalumab with four cycles of conventional chemotherapy followed by maintenance therapy demonstrated prolonged overall survival (OS) and placed as the standard treatment option. However, median progression-free survival (PFS) of both study was only 5.2 months and 5.1 months, despite the objective response rate showing 60.2% and 79%. This finding suggest further development of maintenance treatment strategy to prolonged longer duration of response to the treatment.
In addition to the conventional treatment, Tarlatamab (AMG757), bispecific t-cell engager (BiTE), designed to engage DLL3 on SCLC and CD3 on T-cell has been tested in SCLC. DLL3 is expressed in more than 80% of patients with SCLC, regardless of disease stage and researched for the potential target protein for the antibody based treatment in SCLC. By targeting DLL3 using Tarlatamab, engagement of tumor antigen and CD3 lead to cytotoxic synapse formation, triggering the release of proinflammatory cytokines, perforin, and granzymes from activated T-cells, potentially resulting apoptosis. The first clinical outcome of Tarlatamab was reported from the DeLLphi-300 study, phase 1 dose exploration study, showing confirmed partial response in 23% of the heavily treated SCLC and 37% of the patients showed decrease in tumor burden. Median duration of response was 13.0 months (95% confidential interval CI: 6.2 - 14.9 months), median PFS of 3.7 months and median OS was 13.2 months. In the treatment naïve SCLC, DeLLphi-303 study, phase 1b study combining tarlatamab + PD-L1 inhibitor + carboplatin and etoposide, is ongoing to evaluate the clinical efficacy in the front line setting which include only histologically confirmed extensive disease SCLC population (NCT05361395).
Based on previous clinical and pre-clinical outcomes, showing similar disease characteristics between transformed SCLC from the adenocarcinoma who treated with EGFR TKI with de novo SCLC, this study is designed to evaluate the clinical efficacy of tarlatamab with currently standard treatment in transformed SCLC.

As a core component of comprehensive breast cancer treatment, chemotherapy frequently induces chemotherapy-induced peripheral neuropathy (CIPN), particularly with taxane-based agents. The incidence of CIPN reaches 68.1% within the first month of chemotherapy, and over 30% of patients experience persistent symptoms for more than 6 months. The resulting sensorimotor dysfunction significantly impairs patients' quality of life, necessitates dose reduction or treatment discontinuation, and ultimately affects survival outcomes. Currently, no prophylactic pharmacological or non-pharmacological interventions have received Grade I recommendations in domestic or international guidelines and expert consensuses. The compression therapy demonstrated definite preventive value in the POLAR trial. Its low cost and high tolerability confer substantial clinical applicability, earning it a Grade III recommendation in ESMO guidelines. Meanwhile, single-arm trials of acupuncture have reported a 51.2% symptom relief rate and a trend toward reduced high-grade CIPN. As non-pharmacological interventions, acupuncture and compression therapy hold complementary potential in preventing taxane-induced CIPN: compression therapy locally blocks drug exposure, while acupuncture systemically regulates neural function.However, three core challenges persist in the current research field: insufficient evidence quality for single-intervention strategies, lack of systematic evaluation of combined interventions, and the absence of risk-stratified prevention models. To address these gaps, this study aims to conduct a prospective randomized controlled trial to concurrently evaluate the preventive efficacy of compression therapy, acupuncture, and their combination for taxane-induced CIPN. The goal is to provide high-level evidence-based medicine to support the development of individualized prevention strategies.
