Small cell lung cancer (SCLC) is a very aggressive disease, characterised by rapid growth, high response rates to both chemotherapy and radiotherapy and subsequent development of treatment resistance in the vast majority of patients. In the past 30 years, little progress has been made in systemic treatments and the established management paradigm of platinum-based chemotherapy has reached an efficacy plateau. Several clinical trials have investigated targeted therapies, without producing clinically significant benefits. Recently presented early phase clinical trials with immune checkpoint inhibitors (blockade of the cytotoxic T-lymphocyte antigen-4 (CTLA-4) and blockade of the programmed cell death-1 (PD-1) receptor) have shown promising results. In this review, we present the emerging evidence on immune checkpoint blockade for SCLC.

Background: Prostate cancer is the most common diagnosed tumor and the fifth cancer related death among men in Europe. Although several genetic alterations such as ERG-TMPRSS2 fusion, MYC amplification, PTEN deletion and mutations in p53 and BRCA2 genes play a key role in the pathogenesis of prostate cancer, specific gene alteration signature that could distinguish indolent from aggressive prostate cancer or may aid in patient stratification for prognosis and/or clinical management of patients with prostate cancer is still missing. Therefore, here, by a multi-omics approach we describe a prostate cancer carrying the fusion of TMPRSS2 with ERG gene and deletion of 16q chromosome arm.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer known for its high aggressiveness and poor prognosis. Conventional treatment of TNBC is challenging due to its heterogeneity and lack of clear targets. Recent advancements in immunotherapy have shown promise in treating TNBC, with immune checkpoint therapy playing a significant role in comprehensive treatment plans.

Background: Immune checkpoint inhibitors (ICIs) alone or in combination with standard chemotherapy for advanced urothelial carcinoma (UC) have been tested as first-line treatment in clinical trials. This study aimed to evaluate the clinical outcomes of programmed cell death 1 (PD-1) inhibitor alone or combined with chemotherapy for patients with locally advanced or metastatic UC in a real world clinical care setting, and sought to identify prognostic factors for overall survival (OS).
Methods: A retrospective, real-world study involving 35 locally advanced or metastatic UC patients treated with PD-1 inhibitor alone or in combination with chemotherapy was conducted.

Background/aim: Immune checkpoint blockade has achieved great success as a targeted immunotherapy for solid cancers. However, small molecules that inhibit programmed death 1/programmed death ligand 1 (PD-1/PD-L1) binding are still being developed and have several advantages, such as high bioavailability. Previously, we reported a novel PD-1/PD-L1-inhibiting small compound, SCL-1, which showed potent antitumor effects on PD-L1 tumors.

Background/aim: Chemoimmunotherapy has improved overall survival in patients with extensive small-cell lung cancer (SCLC). However, the backgrounds of patients enrolled in clinical trials tend to differ from those of patients treated in clinical practice, and the effectiveness of chemoimmunotherapy may be unclear in some populations, including patients with poor performance status. This study aimed to evaluate the effectiveness of chemoimmunotherapy for SCLC patients in clinical practice while focusing on several subgroups.
