BACKGROUND: TP53 mutations have a prognostic significance in relapsed and refractory diffuse large B-cell lymphoma (rrDLBCL) patients, and their treatment still faces a great challenge. This study aimed to evaluate the prognosis of patients with TP53 mutations (TP53mut) in the context of CAR-T therapy (Chimeric antigen receptor T-cell therapy) as well as explore the heterogeneity in their cohort and identify the possible risk factors. METHODS: A retrospective study was conducted to investigate the clinical characteristics of rrDLBCL patients with TP53 mutations and their prognostic factors, receiving CAR-T therapy...

BACKGROUND: Loss of HER2 "positivity" can occur in patients with residual disease after neoadjuvant treatment, but the incidence of HER2-positivity loss after neoadjuvant dual HER2-targeted treatment plus chemotherapy, the current standard-of-care for most early stage HER2-positive breast cancers, is not well described. Previous studies that report the HER2 discordance rate after neoadjuvant treatment also do not include the novel HER2-low category. In this retrospective study, we determine the incidence and prognostic impact of HER2-positivity loss, including the evolution to HER2-low disease, after neoadjuvant dual HER2-targeted therapy with chemotherapy...

PURPOSE: Microcalcification (MC) is a valuable diagnostic indicator to detect invasive breast cancer (IBC). This study aimed to determine the clinicopathological features of IBC with MC and detect biomarkers related to the potential mechanism of the MC formation in IBC. METHODS: Data from 364 patients with IBC were collected for the clinical characteristic analysis. The analysis of clinical data helped us to establish a predictive model of axillary node metastasis (ANM) before surgery...

PURPOSE: Ovarian clear cell carcinoma (OCCC) is a distinct and highly malignant subtype of ovarian cancer with high individual heterogeneity in survival that requires specific prognostic predictive tools. Thus, this study aimed to construct and validate nomograms for predicting individual survival in OCCC patients. METHODS: In total, 91 patients with OCCC who were diagnosed and treated at Renji Hospital between 2010 and 2020 were extracted as the training cohort, then 86 patients from the First Affiliated Hospital of USTC were used as the external validation cohort...

BACKGROUND: Symptom burden in adolescents and young adults (AYA) with cancer is poorly characterized but impacts quality of life. METHODS: All Ontario, Canada AYA aged 15-29 years at diagnosis between 2010 and 2018 were linked to population-based healthcare databases, including to Edmonton Symptom Assessment System-revised (ESAS) scores, an 11-point scale routinely obtained at the time of cancer-related outpatient visits and collected provincially. Multistate models estimated mean duration of symptom severity states [none (0) vs...

BACKGROUND: To assess urinary symptoms and urine cytology as screening tools for cystoscopic detection of local recurrence after bladder-preserving trimodality treatment (TMT). METHODS: Patients with muscle-invasive bladder cancer receiving definitive TMT follow-up three monthly for 2 years, six monthly for the next 3 years and then yearly, with a clinical review, urine cytology and cystoscopy at each visit (triple assessment, TA). Grade 2+ cystitis/haematuria absent/present was scored 0/1, and urine cytology reported negative/suspicious or positive was scored 0/1, respectively...

BACKGROUND: Previous studies had explored the diagnostic or prognostic value of NRP-1/CD304 in blastic plasmacytoid dendritic cell neoplasm (BPDCN), acute myeloid leukemia (AML), and B-cell acute lymphoblastic leukemia (B-ALL), whereas the expression and application value of NRP-1/CD304 in other common hematological diseases have not been reported. METHODS: Bone marrow samples from 297 newly diagnosed patients with various hematological diseases were collected to detect the expression of NRP-1/CD304 by flow cytometry (FCM)...

BACKGROUND: Cancer-related cognitive impairment (CRCI) is a frequent consequence in breast cancer survivors after chemotherapy and lowers their quality of life (QOL). Psychological distress is frequently experienced by breast cancer survivors. There are currently few studies investigating the role of psychological distress in the genesis of CRCI. METHODS: In total, 122 breast cancer survivors after standard chemotherapy within a year were recruited and assessed using the Psychological Distress Thermometer (DT)...

BACKGROUND AND AIM: Programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) inhibitors have transformed the treatment landscape of advanced hepatocellular carcinoma (HCC), but consistent responses are not observed in all patients, and prognostic biomarkers to guide treatment decisions are lacking. We aimed to evaluate the predictive value of PD-L1 expression in advanced HCC patients treated with PD-1/PD-L1 inhibitors. METHODS: A comprehensive search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted...

BACKGROUND: The first HPV-vaccine eligible cohorts in the Netherlands will enter the cervical screening program in 2023. However, a substantial number of young women already have had a cervical sample taken before entry into the regular screening program. This study was initiated to explore early effects of HPV vaccination on detection of cytological abnormalities in cervical samples of women younger than the screening age. METHODS: Results of cervical samples were obtained from the Dutch National Pathology Databank (PALGA) and were linked to the women's HPV vaccination status from the national vaccination registry (Praeventis) (N = 42,171)...

Immune checkpoints are protein molecules expressed on the immune cell membrane, which regulate the immune system to kill tumor cells. As an essential immune checkpoint, overexpressed PD-1 on tumor cells could inhibit T-cell activation after being bonded to PD-1. Due to this inhibitory effect, T-cell proliferation and cytokine secretion are suppressed, leading to immune escape of tumor cells. Here, we established a high-throughput method based on cell function screening technology to screen drugs regulating PD-L1 expression in tumor cells at the transcriptional level...

INTRODUCTION: The effectiveness and safety of immune checkpoint inhibitor (ICI) monotherapy in advanced upper tract urothelial carcinoma (UTUC) is less reported. METHODS: In total, 106 consecutive advanced UTUC patients receiving ICI monotherapy were collected from nine high volume centers. Clinical outcomes were analyzed according to multiple parameters (e.g., treatment line, metastatic sites). Objective response rate (ORR), overall survival (OS) and progression-free survival (PFS) were captured after ICI initiation...

OBJECTIVE: To assess the diagnostic value and clinical significance of nucleoporin 107 (NUP107) in hepatocellular carcinoma (HCC), and explore the possible mechanisms. METHODS: The transcriptomic and clinical data of HCC patients were retrieved from The Cancer Genome Atlas (TCGA) and GEO databases. Tissue specimens were collected from HCC patients in the Guangxi area. According to the expression levels and prognostic characteristics of NUP107, ROC curves and nomogram models were constructed using the R package...

BACKGROUND: Lymphovascular invasion (LVI) and perineural invasion (PNI) are associated with poorer prognosis in several human malignancies, but their significance in gastric cancer (GC) remains to be clearly defined. Our study aimed to investigate the prognostic value of LVI/PNI in patients with curative resected GC. METHODS: Records of 1488 patients with stage I--III GC and 3327 patients with stage I-III colorectal cancer (CRC) were reviewed retrospectively, and difference in the incidence of LVI/PNI between GC and CRC was compared...

BACKGROUND: Although early diagnosis and surgical resection of the tumor have been shown to be the most important predictors of lung cancer survival, long-term survival for surgically-resected early-stage lung cancer remains poor. AIMS: In this prospective study we aimed to investigate the survival and prognostic factors of surgically-resected early-stage non-small cell lung cancer (NSCLC) in Central and Eastern Europe. METHODS: We recruited 2052 patients with stage I-IIIA NSCLC from 9 centers in Russia, Poland, Serbia, Czech Republic, and Romania, between 2007-2016 and followed them annually through 2020...

AIM: We constructed a multicentre cohort in China to analyse the differences in clinical characteristics, treatment strategies and prognoses between breast neuroendocrine carcinoma (NEC) and invasive ductal carcinoma (IDC) of the breast. METHODS: All patients with early-stage breast cancer who attended three hospitals in Beijing from 2000 to 2018 were included in the study. We used propensity score matching to make a 1:3 match between NEC and IDC. RESULTS: After propensity score matching, 153 patients with IDC and 51 patients with NEC were analysed...

BACKGROUND: Neuroendocrine neoplasm (NEN) of the gallbladder is rare. It is usually asymptomatic and occurs in older adults. Its clinicopathological characteristics remain controversial, and the diagnosis and treatment strategies are usually based on models of adenocarcinoma. The present study aimed to investigate the clinical characteristics and prognosis of gallbladder NEN. METHODS: The data of patients with gallbladder NEN admitted to Peking Union Medical College Hospital was reviewed, and a database was established for retrospective analysis...

BACKGROUND: Premature aging has been identified as a global risk factor for cancer. Causes of premature aging are multifactorial, including inflammation, infection, chronic stress, and lifestyle factors. METHOD: We evaluated whether premature aging in people living with HIV (PLWH) was associated with antiretroviral therapy (ART) or the diagnosis of cancer. We used well-established DNA methylation patterns to assess premature aging, using Horvath et al., in individuals with HIV located in Cleveland, Ohio and compared these to standardized datasets of US historical blood samples...

BACKGROUND: Current guidelines recommend using filgrastim or tbo-filgrastim to mobilize hematopoietic progenitor cells in an autologous setting. However, previous studies have suggested other forms of granulocyte colony-stimulating factor (G-CSF) are equally efficacious, possibly with fewer leukaphereses required. Thus, we prospectively studied the efficacy of lenograstim, a glycosylated recombinant form of G-CSF, in multiple myeloma (MM) patients. METHODS: From November 2011 to January 2020, 98 MM patients undergoing autologous stem cell transplant (ASCT) from five academic centers in Korea were enrolled...

BACKGROUND: The efficacy and toxicity profiles for extensive-stage small cell lung cancer (ES-SCLC) are unclear. We aimed to address this gap through a Bayesian network meta-analysis. METHODS: We performed network analysis from randomized controlled trials comparing these treatments: PD-(L)1 inhibitor, CTLA-4 inhibitor, CXCR inhibitor, PARP inhibitor, CDK inhibitor, chemotherapy, and their combinations. Pooled estimations of progression-free survival, overall survival, objective response rate, and toxicity (systematic and specific) were conducted within the Bayesian framework...
