BACKGROUND: New biomarkers of progression in patients with prostate cancer (PCa) are needed to improve their classification and clinical management. This systematic review investigated the relationship between single nucleotide polymorphisms (SNPs) and PCa progression. METHODS: A keyword search was performed in Pubmed, EMBASE, Scopus, Web of Science, and Cochrane for publications between 2007 and 2022. We included articles with adjusted and significant associations, a median follow-up greater than or equal to 24 months, patients taken to radical prostatectomy (RP) as a first therapeutic option, and results presented based on biochemical recurrence (BCR)...

Cisplatin-based therapies are standard-of-care for advanced-stage head and neck squamous cell carcinoma (HNSCC). Treatment regimens include 3 weeks of high-dose bolus cisplatin or 6-7 weeks of low-dose weekly cisplatin, both with concurrent radiation. The effects of cisplatin dosage on swallowing function warrant further study. A 237-patient cohort treated for HNSCC at a single center were studied retrospectively. Gastrostomy tube dependence served as the primary endpoint. Secondary endpoints included weight changes, esophageal stricture, and lymphedema...

The aim of the study was to demonstrate the most common genetic alterations and evaluate possible targets involving PIK3/AKT/mTOR signaling and DNA damage repair (DDR) pathways for personalized treatment in patients with NMIBC. Alterations of these pathways were observed in 89.5% and 100% of patients, respectively. Among them, BARD1 was more frequently altered in low/intermediate-risk cases, but PARP4 was more frequently affected in intermediate/high-risk patients. The possible target feasibility of BARD1 and PARP4 alterations should be evaluated for personalized treatment using PARP-inhibitors in NMIBC...

We employed a Markov model to simulate outcomes for a cohort of 1,000 hypothetical patients, comparing improvements in early detection, side effect management, and palliative care over a ten-year period. This model showed benefits in early detection and proactive health management, improving disease stability and reducing mortality rates. This protocol resulted in an 85.8% five-year survival rate, compared to 69.5% under standard protocol. Cost-effectiveness analysis showed significantly reduced costs and improved quality-adjusted life years...

Colorectal cancer (CRC) is the fourth most commonly diagnosed malignant condition in the world. Micro RNAs (miRNAs) as well as epithelial to mesenchymal transition (EMT) play an important role in the pathogenesis of CRC. We performed a comparative analysis of the expression of selected miRNA genes and EMT markers in bioptic samples from patients (n = 45) with primary CRC or metastatic (m)CRC to the regional lymph node using reverse transcription-quantitative PCR and IHC staining. Results: Out of all miRNA analyzed, the miR-17 expression was most significantly different and associated with lower risk of CRC spread to the lymph node...

OBJECTIVE: Regular screening can lead to early diagnosis of breast cancer. Australia is one of the countries with a high rate of participation in breast cancer screening, while in Iran, most patients are diagnosed in advanced stages. This qualitative study used a thematic analysis method to examine the attitudes and beliefs of Iranian and Australian women toward breast cancer and breast cancer screening. METHOD: In-depth interviews were conducted with eight Iranian and seven Australian women...

BACKGROUND: Immunogenic cell death (ICD) is known for releasing damage-associated molecular patterns (DAMPs) from tumor cells. We aimed to find ICD signals by assessing the variation of plasmatic DAMPs (HMGB1, S100A8) before-after standard of care (SoC) systemic treatment in patients with advanced solid tumors. METHODS: Patients scheduled to start a new line of systemic treatment were included. Plasmatic concentrations of HMGB1 and S100A8 were measured (ng/mL) before and after three months of treatment...

ObjectivesWe aimed to assess the effects of pretreatment neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios on the response to neoadjuvant chemotherapy and survival rates in patients with extremity osteosarcoma.Patients and methodsPatients with high-grade osteosarcoma admitted to oncologic centers affiliated to Iran University of Medical Sciences, Tehran, Iran from 2015 to 2021 were evaluated retrospectively to assess the impact of complete blood count related parameters on the pathologic response after neoadjuvant chemotherapy...

Introduction melanoma patients who become stage III after a positive sentinel node biopsy (SNB) may have several patterns of recurrence patients and methods retrospective analysis of melanoma patients who have undergone SNB in a single institution from 2000 to 2015. Results There were 111 recurrences (45.1%) among 246 (20.3%) SNB positive patients and median DRFS was 77.7 months. After initial treatment, further recurrences occurred in 68 (77.3%) patients, regardless the site of initial recurrence conclusions multimodal strategies are recommended to achieve better results when managing stage III melanoma patients after a positive SNB...

We assessed the efficacy, tolerability, and cost-effectiveness of a novel neoadjuvant regimen comprising docetaxel-cyclophosphamide alternating with epirubicin-cisplatin (ddDCEP) administered biweekly for 16 weeks in 116 patients with early triple-negative breast cancer. This regimen achieved a high pathological complete response (ypT0/TisN0) rate of 55.2% and favorable survival outcomes (30-month event-free survival, 91.2%; overall survival, 97%). Febrile neutropenia was observed in 4.3% of patients, and 98% completed at least six of eight cycles...

We sought to examine differences in anxiety, depression and coping strategies among younger (<64 years old) and older (≥65 years old) patients. Patients were assessed at baseline (T1), mid-point (T2) and on the last day of treatment (T3) using the Hospital Anxiety and Depression Scale and the Ways of Coping. Linear mixed modeling approach was used. The study included 200 patients (gender: 70% women; diagnosis: 30% breast, 22% hematological, 18% gastrointestinal; disease stage: 60% advanced). Older patients who used an emotion-focused coping strategy had a greater decrease in anxiety at T3 compared to those that used problem-focused coping (p = 0...

Aims: This narrative review seeks to identify the SINS score application in the radiation oncology field. Methods: This literature review was performed searching papers on MEDLINE published from January 2010 to August 2022. Results: In terms of vertebral painful lesions and RT symptomatic responses, SINS score could be an interesting aid in order to choose the right therapeutic approach. Lesions with higher level of instability, and therefore higher SINS score, could did not find any significant benefit from radiation therapy which is more effective on the tumor-related pain component...

RET proto-oncogene encodes receptor tyrosine kinase. Selpercatinib and pralsetinib are the only RET-specific tyrosine kinase inhibitors approved by FDA in RET-altered tumors. We searched PubMed, Embase, Cochrane, WOS and Clinicaltrials.gov. Objective-response, complete-response, and partial-response were 60%-89%, 0-11%, and 55%-89%, respectively with the use of RET-specific drugs. ≥Grade 3 adverse events were seen in 28%-53% of the patients, with hypertension, change in ALT, QT prolongation, neutropenia, and pneumonitis among the common side effects...

This study aimed to reveal the drug repurposing candidates for colorectal cancer (CRC) via drug repurposing methods and network biology approaches. A novel, differentially co-expressed, highly interconnected, and co-regulated prognostic gene module was identified for CRC. Based on the gene module, polyethylene glycol, gallic acid, pyrazole, cordycepin, phenothiazine, pantoprazole, cysteamine, indisulam, valinomycin, trametinib, BRD-K81473043, AZD8055, dovitinib, BRD-A17065207, and tyrphostin AG1478 presented as drugs and small molecule candidates previously studied in the CRC...

Spindle cell/sclerosing rhabdomyosarcoma (SSRMS) is a clinicopathologically and molecularly heterogeneous disease. Gene fusions have been identified in intraosseous SSRMS, consisting predominantly of EWSR1 / FUS :: TFCP2 and MEIS1 :: NCOA2 . The former often follow an aggressive clinical course; there is limited clinical follow-up available for the latter. We report here a new case of the very rare intraosseous SSRMS with MEIS1 :: NCOA2 gene fusion and include the detailed treatment course and 52 months of clinical follow-up...
