Longitudinal Assessment of Cognitive Function in Survivors of Testicular Germ Cell Tumor.

Background And Objective: Survivors of testicular germ cell tumor (TGCT) may experience long-term cognitive changes. The aim of our prospective study was to longitudinally assess cognitive function among TGCT survivors to identify potential lasting cognitive changes over a period of 5 yr.

Methods: TGCT survivors (n = 151) completed Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) questionnaires annually, with median time to first follow-up visit (FUV) of 8 (range 4-24) yr since completion of treatment.

Chemotherapy-Induced Peripheral Neuropathy (CIPN) as a Predictor of Decreased Quality of Life in Testicular Germ Cell Tumor Survivors.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) after curative treatment for testicular germ cell tumors (GCTs) has been previously reported. It has been shown that CIPN can contribute to impaired quality of life (QOL) in cancer survivors. Herein, we aimed to evaluate CIPN in association with QOL in GCT survivors.

Prognostic role of plasma vitamin D and its association with disease characteristics in germ cell tumours.

Background: Testicular cancer is the most common malignancy among young men. Vitamin D has pluripotent effects on cancer pathogenesis and plays a role in the metastatic cascade. The aim of this study is to analyze plasma vitamin D in association with clinico-pathological findings and prognosis in patients with germ-cell tumors (GCTs).

Cognitive impairment and biomarkers of gut microbial translocation in testicular germ cell tumor survivors.

Background: Survivors of testicular germ cell tumors (GCT) may suffer from late cognitive impairment. We hypothesized that disruption of intestinal barrier during chemotherapy and/or radiotherapy may be a contributing factor of cognitive dysfunction within the gut-blood-brain axis.

Methods: GCT survivors (N = 142) from National Cancer Institute of Slovakia completed the Functional Assessment of Cancer Therapy Cognitive Function questionnaires during their annual follow-up visit at 9-year median (range 4-32).

Changes in CoQ/Lipids Ratio, Oxidative Stress, and Coenzyme Q during First-Line Cisplatin-Based Chemotherapy in Patients with Metastatic Urothelial Carcinoma (mUC).

Oxidative stress plays an important role in cancer pathogenesis, and thiobarbituric acid-reactive substance level (TBARS)—a parameter of lipid peroxidation—has prognostic significance in chemotherapy-naive patients with metastatic urothelial carcinoma (mUC). However, the effect of cisplatin (CDDP)-based chemotherapy on oxidative stress, coenzyme Q10, and antioxidants remains unknown. The objective of this prospective study was to determine possible changes in the CoQ10 (coenzyme Q10)/lipids ratio, antioxidants (α-tocopherol, γ-tocopherol, β-carotene, CoQ10), total antioxidant status (TAS), and TBARS in plasma at baseline and during first-line chemotherapy based on CDDP in mUC subjects.

Effects of primary granulocyte-colony stimulating factor prophylaxis on the incidence of febrile neutropenia in patients with germ cell tumors.

Testicular germ cell tumors (GCTs) are the most common solid malignancy in males aged 15-35 years. Febrile neutropenia (FN) is a serious complication of chemotherapy that frequently occurs in patients with GCTs. The present retrospective study aimed to evaluate the effect of primary granulocyte-colony stimulating factor (G-CSF) prophylaxis on the incidence of FN in patients with GCTs.

Factors Associated With Choriocarcinoma Syndrome Development in Poor-Risk Patients With Germ Cell Tumors.

Background: Germ cell tumors (GCTs) represent a highly curable cancer. However, a small proportion of poor-risk patients can develop choriocarcinoma syndrome (CS) connected with acute respiratory distress syndrome (ARDS) with a high mortality rate. Our retrospective study aimed to determine the risk factors of poor-risk GCTs susceptible to CS development.

Comprehensive Assessment of Selected Immune Cell Subpopulations Changes in Chemotherapy-Naïve Germ Cell Tumor Patients.

The pattern of immune cell distribution in testicular germ cell tumors (GCT) significantly differs from the immune environment in normal testicular tissues. The present study aimed to evaluate the role of different leukocyte subpopulation in GCTs. A cohort of 84 chemotherapy-naïve GCT patients was analyzed.

Paclitaxel, Ifosfamide, and Cisplatin in Patients with Poor-prognosis Disseminated Nonseminomatous Germ Cell Tumors with Unfavorable Serum Tumor Marker Decline After First Cycle of Chemotherapy. The GCT-SK-003 Phase II Trial.

Background: Germ cell tumors represent highly curable disease even in metastatic stage. However, poor-risk patients with an unfavorable serum tumor marker (STM) decline after the first cycle of chemotherapy represent a subgroup with dismal prognosis, with approximately 50% cure rate using bleomycin, etoposide, and cisplatin (BEP).

Objective: The aim of this study was to determine the efficacy and safety of paclitaxel, ifosfamide, and cisplatin (TIP) in this patient population.

Survival Prediction by Baseline Systemic Immune-inflammation Index (SII) and its Changes During First-line Platinum-based Treatment in a Caucasian Population of Patients With Metastatic Urothelial Carcinoma (MUC).

Background/aim: Systemic immune-inflammation index (SII) predicts survival of patients with various malignancies. This study explored the prognostic value of SII in metastatic urothelial carcinoma (MUC) subjects.

Patients And Methods: We evaluated 181 consecutive MUC patients treated with first-line platinum-based therapy.

Are Changes in the Percentage of Specific Leukocyte Subpopulations Associated with Endogenous DNA Damage Levels in Testicular Cancer Patients?

Chemoresistance of germ cell tumors (GCTs) represents an intensively studied property of GCTs that is the result of a complicated multifactorial process. One of the driving factors in this process is the tumor microenvironment (TME). Intensive crosstalk between the DNA damage/DNA repair pathways and the TME has already been reported.

Prognostic Value of Apoptosis-Inducing Factor (AIF) in Germ Cell Tumors.

Apoptosis is a strictly regulated process essential for preservation of tissue homeostasis. This study aimed to evaluate expression of apoptosis inducing factor (AIF) in testicular germ cell tumors (GCTs) and to correlate expression patterns with clinicopathological variables. Formalin-fixed and paraffin-embedded specimens of non-neoplastic testicular tissue and GCTs obtained from 216 patients were included in the study.

Intricacies of Radiographic Assessment in Testicular Germ Cell Tumors.

Testicular germ cell tumors (GCTs) are malignancies with a unique biology, pathology, clinical appearance, and excellent outcomes. A correct radiographic assessment of GCTs is extremely important for the clinical management in several typical scenarios. Advancements in the field of diagnostic medicine bring an increasing number of sophisticated imaging methods to increase the performance of imaging studies.

Squamous cell carcinoma of the colon - a case report.

Background: Primary squamous cell carcinomas (SCC) of the colon are extremely rare and occur predominantly in the fifth decade of life, with a slight prevalence in men. The most common anatomical sites are the rectum and the proximal colon. Clinical signs and common dia-gnostic methods cannot clearly distinguish SCC from adenocarcinoma.

Complete Response to Chemotherapy in Metastatic Pancreatic Carcinoma Associated with Double Heterozygous Germline Mutation in BRCA2 and CHEK2 Genes - a Case Report.

Background: Metastatic pancreatic carcinoma is an aggressive disease with adverse prognosis. Despite slight advances in chemotherapy, complete remission of the disease is extremely rare.

Case: In this article we present a case of a patient with initially metastatic pancreatic adenocarcinoma, associated with double heterozygous germline mutation in BRCA2 and CHEK2 genes, with the description of clinical, radiological and histomorphological characteristics of the disease as well as the dia-gnostic and therapeutic procedure.

DNA damage measured in blood cells predicts overall and progression-free survival in germ cell tumour patients.

Germ cell tumour (GCT) patients who fail to respond to chemotherapy or who relapse have a poor prognosis. Timely and accurately stratifying such patients could optimise their therapy. We identified endogenous DNA damage levels as a prognostic marker for progression-free (PFS) and overall (OS) survival in chemotherapy-naïve GCT patients.

Increased levels of XPA might be the basis of cisplatin resistance in germ cell tumours.

Background: Germ cell tumours (GCTs) represent a highly curable malignity as they respond well to cisplatin (CDDP)-based chemotherapy. Nevertheless, a small proportion of GCT patients relapse or do not respond to therapy. As this might be caused by an increased capacity to repair CDDP-induced DNA damage, identification of DNA repair biomarkers predicting inadequate or aberrant response to CDDP, and thus poor prognosis for GCT patients, poses a challenge.

High Endogenous DNA Damage Levels Predict Hematological Toxicity in Testicular Germ Cell Tumor Patients Treated With First-Line Chemotherapy.

Background: Testicular germ cell tumors (TGCTs) are an excellent example of chemosensitive disease. However, cisplatin-based chemotherapy has significant side effects, including myelosuppression. Previously, we found endogenous DNA damage level in peripheral blood mononuclear cells (PBMCs) to be an independent prognostic marker.

Intraoperative tumor lysis syndrome in a giant teratoma: a case report.

Background: Tumor lysis syndrome is an unusual metabolic emergency in solid tumors. Perioperative occurrence of this syndrome is extremely rare but may have fatal consequences if not detected and treated on time.

Case Report: We report a 19-year patient with testicular germ cell tumor after first line chemotherapy with giant growing teratoma syndrome in retroperitoneum.

Severe Complications in Testicular Germ Cell Tumors: The Choriocarcinoma Syndrome.

Testicular germ cell tumors (TGCTs) represent the most common solid tumor in young men and is a model of curable cancer. The effectiveness of cisplatin-based chemotherapy secures more than 95% of patients' 5-years survival rate. However, some high-risk patients with a very advanced disease develop choriocarcinoma syndrome (CS) connected with acute respiratory failure with poor prognosis and high mortality rate shortly after beginning systemic chemotherapy.

βcatenin is a marker of poor clinical characteristics and suppressed immune infiltration in testicular germ cell tumors.

Background: WNT/βcatenin (WNTβ) pathway is activated in early stages of embryonic development. We aimed to evaluate the significance of βcatenin in germ cell tumors (GCTs) and explore associations with the inflamed environment.

Methods: Surgical specimens from 247 patients were analyzed.

Systemic immune-inflammation index in germ-cell tumours.

Background: We evaluated systemic immune-inflammation index (SII) and its association with patient outcome in germ-cell tumours (GCTs).

Methods: Two independent cohorts of patients were analysed; the discovery set (n=171) from a single institution and the validation set (n=181) previously included in a study evaluating PD-L1 in GCTs. The SII was calculated using platelet (P), neutrophil (N) and lymphocyte (L) counts before chemotherapy and correlated with survival using regression analyses and Kaplan-Meier method.
