Article Abstract
Unlabelled: HISTORY AND DIAGNOSIS: A 59-year old engineer was admitted to the hospital because of pain in his right collar region and the onset of incomplete paresis of the right arm. Magnetic resonance tomography displayed an advanced tumour arising from the right paravertebral soft tissue. Histological examination revealed a malignant peripheral nerve sheath tumor (MPNST). Thirteen years before admission, the patient had a right-sided tumor-tonsillectomy of a squamous cell carcinoma and local radiation of a cystic squamous cell carcinoma in the ipsilateral cervical soft tissue.
Clinical Course And Therapy: In the following course, progressive neurological symptoms occurred including beginning paraplegia, right phrenic paralysis and a severe concomitant pain syndrome. Due to the location and advanced tumor state, surgical treatment was not performed and palliative chemotherapy remained ineffective. Three months later the patient died due to rapidly progressive neurological failure.
Conclusion: MPNST represents a rare entity which has been related to postoperative radiation. Unusual neurological symptoms in anatomical regions of former radiation should therefore include neurogenic secondary malignancies in the differential diagnosis for early surgical intervention.

Complete blood counts as potential risk factors of early dissemination to liver and lungs in resected colorectal cancer: a retrospective cohort study.
Int J Colorectal Dis
January 2025
Department of Pathomorphology, Medical University of Gdańsk, Gdańsk, Poland.
Purpose: Liver and lung metastases demonstrate distinct biological, particularly immunological, characteristics. We investigated whether preoperative complete blood count (CBC) parameters, which may reflect the immune system condition, predict early dissemination to the liver and lungs in colorectal cancer (CRC).
Methods: In this retrospective single-centre study, we included 268 resected CRC cases with complete 2-year follow-up and analysed preoperative CBC for association with early liver or lung metastasis development.
The emergence of DNAM-1 as the facilitator of NK cell-mediated killing in ovarian cancer.

Introduction: Ovarian cancer (OC) is the sixth most common malignancy in women and the poor 5-year survival emphasises the need for novel therapies. NK cells play an important role in the control of malignant disease but the nature of tumour-infiltrating and peripheral NK cells in OC remains unclear.
Methods: Using flow cytometric analysis, we studied the phenotype and function of NK cells in blood, primary tumour and metastatic tissue in 80 women with OC.
Microangiopathic Hemolytic Anemia as the Initial Presentation of Metastatic Signet-Ring Cell Carcinoma of the Colon: A Case Report.

Microangiopathic hemolytic anemia (MAHA) is a condition characterized by intravascular fragmentation of red blood cells, leading to the characteristic finding of schistocytes on a peripheral blood smear. The differential diagnoses of MAHA include thrombotic thrombocytopenic purpura (TTP), hemolytic-uremic syndrome (HUS), disseminated intravascular coagulation (DIC), idiopathic thrombocytopenic purpura (ITP), infections, malignancies, and solid organ transplantation. The commonly associated malignancies with MAHA are gastric, breast, prostate, lung, and lymphoma.

Background: Metabolic reprogramming is increasingly recognized as a crucial factor influencing the development, progression, and prognosis of pancreatic ductal adenocarcinoma (PDAC). Despite this, the potential association of specific metabolic characteristics and PDAC remains ambiguous due to the variability introduced by individual patient differences. In this study, we aimed to find out metabolic pathways that may be associated with the overall survival (OS) of PDAC patients.

Background: Obesity is a risk factor for developing cancer but is also associated with improved outcomes after treatment with immune checkpoint inhibitors (ICIs), a phenomenon called the obesity paradox. To interrogate mechanisms of divergent immune responses in obese and non-obese patients, we examined the relationship among obesity status, clinical responses, and immune profiles from a diverse, pan-tumor cohort of patients treated with ICI-based therapy.
Methods: From June 2021 to March 2023, we prospectively collected serial peripheral blood samples from patients with advanced or metastatic solid tumors who received ICI as standard of care at Johns Hopkins.
