Secondary malignancy

Longitudinal erythronychia (LE) is defined as a longitudinal red band of the nail(s) and is classified as localized (involvement of one nail) or polydactylous (involvement of more than one nail). The differential diagnosis is distinct for these classifications. The etiologies of localized longitudinal erythronychia (LLE) are most frequently benign subungual neoplasms, and less often malignancies. Polydactylous longitudinal erythronychia (PLE) is typically secondary to regional or systemic diseases, including lichen planus and Darier disease...

Background and Objective Chronic myeloid leukemia (CML) is a hematological malignancy with an excellent prognostic outcome. After advancements in CML treatment and the introduction of different tyrosine kinase inhibitors (TKI), the life expectancy of CML patients has become equivalent to that of the general population. As a result, coronary artery disease is anticipated to be the leading cause of death among CML patients. Moreover, TKI use is associated with a risk of endothelial dysfunction, thrombosis, and cardiovascular events, including myocardial infarction...

BACKGROUND: Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is a rare tumor that few cases have been reported until now. In these cases, either a benign teratoma is malignantly transformed into adenocarcinoma or a collision tumor is formed between a mature cystic teratoma and a mucinous tumor, which is either primarily originated from epithelial-stromal surface of the ovary, or secondary to a primary gastrointestinal tract tumor. The significance of individualizing the two tumors has a remarkable effect on further therapeutic management...

OBJECTIVE: To compare insertion failure rates for Pipelle endometrial sampling with a full bladder compared with the standard process (not taking into account bladder status) without cervical manipulation. METHODS: A single-masked randomized trial was conducted in a single tertiary care center from July 2021 to January 2022. Two hundred fourteen participants aged 18 years or older who were scheduled for outpatient Pipelle endometrial sampling were randomized: 107 each to having a full bladder (by oral water intake) or standard process (without delayed sampling and bladder status not taken into account)...

Spreading depolarizations (SDs) occur frequently in patients with malignant hemispheric stroke. In animal-based experiments, SDs have been shown to cause secondary neuronal damage and infarct expansion during the initial period of infarct progression. In contrast, the influence of SDs during the delayed period is not well characterized yet. Here, we analyzed the impact of SDs in the delayed phase after cerebral ischemia and the potential protective effect of ketamine. Focal ischemia was induced by distal occlusion of the left middle cerebral artery in C57BL6/J mice...

BACKGROUND: The only clinically approved drug that reduces doxorubicin cardiotoxicity is dexrazoxane, but its application is limited due to the risk of secondary malignancies. So, exploring alternative effective molecules to attenuate its cardiotoxicity is crucial. Colchicine is a safe and well-tolerated drug that helps reduce the production of reactive oxygen species. High doses of colchicine have been reported to block the fusion of autophagosomes and lysosomes in cancer cells. However, the impact of colchicine on the autophagy activity within cardiomyocytes remains inadequately elucidated...

AIM: To investigate whether age at first sexual intercourse could lead to any changes in the risk of oral cavity cancer. METHODS: A two-sample mendelian randomization was conducted using genetic variants associated with age at first sexual intercourse in UK biobank as instrumental variables. Summary data of Northern American from a previous genome-wide association study aimed at oral cavity cancer was served as outcome. Three analytical methods: inverse variance-weighted, mendelian randomization Egger, and weighted median were used to perform the analysis, among which inverse variance-weighted was set as the primary method...

DESIGN: This study by Laky et al. is a single-centre, double-blinded randomised placebo-controlled clinical trial, examining the effects of micronutrient supplementation in combination with non-surgical hygiene phase therapy (nsHPT) for Stage III and IV periodontal disease. The study was carried out at the Medical University of Vienna (Austria), School of Dentistry. The patients enrolled in the study were randomised to receive a commercially available multi-nutrient supplement (containing: vitamin C, vitamin E, zinc, selenium, alpha-lipoic-acid, cranberry extract, grapeseed extract, and coenzyme Q10) or a cellulose placebo to take for 2 months, alongside a course of non-surgical hygiene phase therapy...

Cytomegalovirus (CMV) reactivation is a prominent complication associated with adverse outcomes in allogeneic hematopoietic stem cell transplantation (HSCT). However, CMV reactivation after allogeneic HSCT may be associated with a lower incidence of relapse in some hematological malignancies. This study analyzed the Japanese registry data from 1,082 patients with myelodysplastic syndrome (MDS) who underwent their first allogeneic HSCT and survived for 100 days after transplantation without graft failure or disease relapse to investigate this association...

Extragonadal germ cell tumors (EGCTs) are rare, representing <5% of all germ cell tumors (GCTs). Whilst EGCTs share morphological and immunohistochemical features with their gonadal counterparts, they tend to be more aggressive and are frequently associated with secondary somatic malignancies. The aim of our study was to evaluate the clinical, morphological and immunohistochemical features, and to analyze tumors for chromosomal abnormalities of 12p, in addition to any novel genetic alterations, in a series of EGCTs...

OBJECTIVES: The association between cancer and IgG4-related disease (IgG4-RD) is evolving. The primary aim of this study was to investigate the prevalence of malignancies in IgG4-RD. The secondary aim was to describe the epidemiological and clinical characteristics of IgG4-RD patients with a history of cancer. METHODS: Two hundred and ten patients with IgG4-RD were included in this retrospective study. IgG4-RD phenotypes, clinical and serological variables were analyzed...

The presence of BRAF mutation in hematological malignancies, excluding Hairy cell leukemia, and its significance as a driver mutation in myeloid neoplasms (MNs) remains largely understudied. This research aims to evaluate patient characteristics and outcomes of BRAF -mutated MNs. Among a cohort of 6667 patients, 48 (0.7%) had BRAF -mutated MNs. Notably, three patients exhibited sole BRAF mutation, providing evidence supporting the hypothesis of BRAF 's role as a driver mutation in MNs. In acute myeloid leukemia, the majority of patients had secondary acute myeloid leukemia, accompanied by poor-risk cytogenic and RAS pathway mutations...

Secondary malignancies are rare but devastating complications of longstanding burn scars. Squamous cell carcinoma is the most common, followed by basal cell carcinoma and melanomas. There are fewer than 50 total reported cases of malignant melanomas arising in burn scars. We report a case of malignant melanoma arising within a longstanding burn scar confirmed by histology, FISH, and PRAME staining to further characterize melanomas arising in burn scars and to illustrate the diagnostic challenges they present...

INTRODUCTION: Recurrent postmenopausal bleeding (PMB) occurs in 6%-25% of postmenopausal women who have experienced a previous episode of PMB. The question of whether recurrent PMB leads to a higher risk of endometrial cancer (EC) in comparison to a single episode of PMB is, however, controversial. Furthermore, little is known about predictive factors for recurrent PMB. MATERIAL AND METHODS: A multicenter prospective cohort study was conducted over a 5-year period in four hospitals in the Netherlands...

BACKGROUND: Cancer remains a global burden, with increasing mortality rates. Current cancer treatments involve controlling the transcription of malignant DNA genes, either directly or indirectly. DNA exhibits various structural forms, including the G-quadruplex (G4), a secondary structure in guanine-rich regions. G4 plays a crucial role in cellular processes by regulating gene expression and telomerase function. Researchers have recently identified G4-stabilizing binding agents as promising anti-cancer compounds...

BACKGROUND: Current guidelines recommend using sequential cardiac imaging to monitor for cancer treatment-related cardiac dysfunction (CTRCD) in patients undergoing potentially cardiotoxic chemotherapy. Multiple different imaging cardiac modalities are available and there are few prospective head-to-head comparative studies to help guide treatment. OBJECTIVES: To perform an exploratory prospective cohort study of "real-world" CTRCD comparing multigated acquisition nuclear ventriculography (MUGA) at the referring cancer specialist's discretion with a novel echocardiographic strategy at an Australian tertiary hospital...

BACKGROUND: Chest-wall sarcomas are treated with extensive resections and complex defect reconstruction to restore chest-wall integrity. It is a difficult surgical procedure that incorporates a multidisciplinary approach for the best outcome, preventing paradoxical chest movement issues and reducing complications. OBJECTIVE: We aimed to describe our experience of chest-wall reconstruction using polypropylene mesh (Marlex® Mesh) combined with methyl-methacrylate and soft-tissue coverage with a latissimus dorsi flap following sarcoma resection...

Langerhans cell histiocytosis (LCH) is a myeloid neoplastic disorder characterized by lesions with CD1a-positive/Langerin (CD207)-positive histiocytes and inflammatory infiltrate that can cause local tissue damage and systemic inflammation. Clinical presentations range from single lesions with minimal impact to life-threatening disseminated disease. Therapy for systemic LCH has been established through serial trials empirically testing different chemotherapy agents and durations of therapy. However, fewer than 50% of patients who have disseminated disease are cured with the current standard-of-care vinblastine/prednisone/(mercaptopurine), and treatment failure is associated with long-term morbidity, including the risk of LCH-associated neurodegeneration...

Allogeneic hematopoietic cell transplantation is a life-saving procedure used to treat of a variety of devastating diseases. It requires hematopoietic stem cells collected via filgrastim mobilized peripheral blood stem cells or bone marrow harvest from volunteer unrelated donors. There is a paucity of safety data regarding donors' long-term adverse events. This prospective, observational study combined peripheral blood stem cell donors enrolled on the NMDP Investigational New Drug trial and bone marrow donors between July 1, 1999, and September 30, 2015...

BACKGROUND: Major abdominal surgery is associated with a high rate of post-operative complications with increased risk of adverse surgical outcomes due to the presence of frailty. This study aims to evaluate the effectiveness of the multimodal Recovery of Surgery in the Elderly (ROSE) prehabilitation program with supervised exercise in mitigating postoperative functional decline when compared to standard care. METHOD: The ROSE program enrolled ambulant patients who were 65 years and above, had a Clinical Frailty Scale score of 4 or more and were planned for major abdominal surgery...
