AI Article Synopsis

  • * A specific case showed a metastatic germ cell tumor with 30% PD-L1 positive cells responded well to the monoclonal antibody toripalimab, leading to lasting remission.
  • * After 36 months of follow-up, the patient maintained remission despite stopping toripalimab after 18 months due to an allergic reaction, suggesting its potential as a salvage therapy.

Article Abstract

The outcome for patients with recurrent and metastatic germ cell tumors can be dismal, and novel salvage therapies are required for these patients. Here we describe a case of metastatic germ cell tumor in which 30% of cells were positive for PD-L1. This tumor achieved a durable response to toripalimab, a monoclonal anti-PD-1 antibody. Follow-up for 36 months post-treatment confirmed no disease progression. Continuous remission was maintained even when treatment was interrupted after 18 months because of an immune-related adverse event (allergic rhinitis). Thus, toripalimab may be an alternative choice for salvage therapy in patients with recurrent and metastatic germ cell tumors.

Paraneoplastic limbic encephalitis (PLE) is a poorly understood condition, thought to be caused by the cross-reacting of tumor antibodies with neurons in the brain, resulting in neuropsychiatric sequelae, such as personality and behavioral changes, psychosis, memory loss, and seizures. Anti-contactin-associated protein-like 2 (CASPR2) antibodies can cause PLE in patients with particular tumors, which in most cases can be identified as thymoma, lung cancer, or endometrial cancer. Some case reports show rare instances with other tumors, such as throat or sigmoid carcinoma.

Background: Pineal region tumors encompass a wide range of pathologies, presenting challenges in pre-surgical characterization and exhibiting variable prognostic outcomes across different tumor types. This study aims to identify key imaging features from pre-treatment magnetic resonance imaging (MRI) of pineal region tumors to aid in prognostic analysis.

Methods: We retrospectively enrolled 33 patients with pineal region tumors who underwent pre-treatment imaging at the Seventh Medical Center of the Chinese PLA General Hospital between January 2010 and June 2023.

Testicular tumors represent the most common solid organ malignancy in young and adult males. Sex cord-stromal tumors are the second-largest group of primary testicular cancers, after germ-cell tumors. Sertoli cell (SC) tumors of the testis are relatively rare, accounting for only a small fraction of testicular tumors.

The sacrum can harbor a diverse group of both benign and malignant tumors, including metastases. Primary tumors of the sacrum can arise from bone, cartilage, marrow, notochordal remnants, or surrounding nerves and vessels. Among a variety of primary tumors of the spine, chordoma, germ cell tumors and Ewing's sarcoma are recognized for their propensity to occur in the sacrum.

Mutations in the mitochondrial (mt) genome contribute to metabolic dysfunction and their accumulation relates to disease progression and resistance development in cancer cells. This study explores the mutational status of the mt genome of cisplatin-resistant -sensitive testicular germ cell tumor (TGCT) cells and explores its association with their respiration parameters, expression of respiratory genes, and preferences for metabolic pathways to reveal new markers of therapy resistance in TGCTs. Using Illumina sequencing with Twist Enrichment Panel, the mutations of mt genomes of sensitive 2102EP, H12.
