Purpose: Bec2 is an anti-idiotypic antibody that mimics GD3, a ganglioside that is expressed on the surface of tumor cells and is of neuroectodermal origin. We assessed whether Bec2/bacille Calmette-Guerin (BCG) vaccination prolongs survival in patients with limited-disease small-cell lung cancer (SCLC) after a major response to chemotherapy and chest radiation.
Patients And Methods: Patients were randomly assigned to receive five vaccinations of Bec2 (2.5 mg)/BCG vaccine or follow-up. Vaccination was given over a 10-week period. The sample size was targeted to detect an increase in median survival of 40% after random assignment, and stratification was by performance status, response, and institution. Quality of life was assessed by using the European Organisation for Research and Treatment of Cancer instrument. Humoral response was assessed in patients who received vaccination.
Results: A total of 515 patients were randomly assigned. The primary toxicities of vaccination were transient skin ulcerations and mild flu-like symptoms. There was no improvement in survival, progression-free survival, or quality of life in the vaccination arm. Median survival from randomization was 16.4 and 14.3 months in the observation and vaccination arms (P = .28), respectively. Among vaccinated patients, a trend toward prolonged survival was observed in those (one third) who developed a humoral response (P = .085). Multivariate analysis showed a positive impact on survival by prior treatment with concomitant chemoradiotherapy, prophylactic cranial irradiation, female sex, low lactate dehydrogenase, and normal platelets.
Conclusion: Vaccination with Bec2/BCG has no impact on outcome of patients with limited-disease SCLC responding to combined-modality treatment. Vaccination strategies in SCLC may still be warranted using vaccines that produce a better immunologic response.

Introduction: Breast cancer liver metastasis presents a significant challenge in clinical oncology, with limited treatment options and poor prognosis. This case series study explores the extended survival achieved in breast cancer patients with liver metastases through a combination of surgical and medical interventions.

Epstein-Barr virus (EBV) is a herpesvirus capable of establishing lifelong latent infections, leading to a wide spectrum of diseases. It can affect multiple organs, including the gastrointestinal tract, typically through lymphoproliferative syndromes or gastric cancer, while acute gastrointestinal disease is rare and poorly understood. Two cases of EBV-induced acute colitis in kidney transplant recipients were described.

Aim: Systemic sclerosis is associated with significant morbidity and mortality. It remains unclear from the literature if there are differences between the subtypes of systemic sclerosis and the rate of hospitalization. Our study investigates the rates of all types of hospitalizations between limited and diffuse cutaneous systemic sclerosis.

TREX1 mutations underlie a variety of human diseases, including retinal vasculopathy with cerebral leukoencephalopathy (RVCL or RVCL-S), a catastrophic adult-onset vasculopathy that is often confused with multiple sclerosis, systemic vasculitis, or systemic lupus erythematosus. Patients with RVCL develop brain, retinal, liver, and kidney disease around age 35-55, leading to premature death in 100% of patients expressing an autosomal dominant C-terminally truncated form of TREX1. We previously demonstrated that RVCL is characterized by high levels of DNA damage, premature cellular senescence, and risk of early-onset breast cancer before age 45.

Background: Subsequent lines of therapy for chemotherapy-resistant metastatic colorectal cancer (CRC) have shown limited efficacy. Herein, we retrospectively investigated the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) using oxaliplatin plus 5-FU/FUDR in patients with unresectable colorectal liver metastases (CRLM) who progressed following standard chemotherapy regimens.
Methods: From March 2017 to April 2023, CRC patients with unresectable CRLM who progressed following standard chemotherapy and subsequently received HAIC oxaliplatin plus 5-FU/FUDR were evaluated.
