5-year Survival Rate Of Patients Research Articles

Treatment Patterns and Clinical Outcomes in Patients with Hodgkin Lymphoma from Saudi Arabia, Türkiye, and South Africa: Subgroup Analysis from the International, Multi-center, Retrospective BHOLISTIC Study.

B-HOLISTIC was a real-world, retrospective study of treatment patterns and clinical outcomes in Hodgkin lymphoma (HL) in regions outside Europe and North America. This subgroup analysis reports findings from Saudi Arabia, Türkiye, and South Africa. Patients aged ≥18 years and diagnosed with stage IIB-IV classical HL receiving frontline chemotherapy (frontline cHL) and/or relapsed/refractory HL (RRHL) from January 2010-December 2013 were assessed. The primary endpoint was progression-free survival (PFS) in patients with RRHL. Overall, 694 patients (RRHL: n=178; frontline cHL: n=653) were enrolled. Among patients with RRHL, >80% received first salvage chemotherapy. The most common first salvage regimens were etoposide, methylprednisolone, cytarabine, cisplatin (ESHAP) in Saudi Arabia (78.3%) and dexamethasone, cytarabine, cisplatin (DHAP) in Türkiye (36.1%) and South Africa (40%). Median PFS (95% confidence interval [CI]) in the RRHL group was 5.1 (3.0-15.9), 19.7 (7.5-not reached), and 5.2 (1.1- 10.1) months in Saudi Arabia, Türkiye, and South Africa, respectively. The 5-year PFS and overall survival (95% CI) rates in patients with RRHL were 33.2% (21.6-45.2) and 78.2% (65.9-86.5) in Saudi Arabia, 42.5% (29.5-54.9) and 79.4% (67.2-87.5) in Türkiye, and 13.1% (4.2-27.0) and 53% (35.5-67.8) in South Africa, respectively. This study showed that the clinical outcomes in Türkiye and Saudi Arabia were generally comparable with Western countries during the study period, although Saudi Arabia had lower PFS rates. Conversely, the clinical outcomes in South Africa were suboptimal, emphasizing the need for novel therapies and improved progression to stem cell transplantation. Additionally, these data may serve as a control group for future studies in these countries and inform clinical decision-making.

Clinicopathological characteristics of mucinous breast cancer: a retrospective analysis of a 6-years study from national cancer center in Vietnam.

To evaluate clinicopathological features in women with mucinous breast cancer (MBC), distinguishing between pure (PMC) and mixed (MMC) subtype. A retrospective analysis of all 358 women with MBC treated at Vietnam National Cancer hospital from June 2015 to December 2020. PMC was defined by ≥ 90% mucinous components. We identified 358 women with MBC (245 PMC and 113 MMC) representing 2.7% of all 13,254 BC patients. The proportions of stage I, II, III and IV were 34.9%, 50.8%, 10.4% and 3.9% respectively. The rate of HER2 overexpression was 12%, and only 1.4% of patients was treated with anti-HER2. 193 patients (53.9%) had chemotherapy, including 55 patients (15.4%) treated in the neoadjuvant setting. Only 3 patients (5.5%) achieved pCR. PMC patients were older (54.4 ± 13.3 vs 51.1 ± 13.1years), had lower Ki67 expression, lower incidence of nodal metastasis (N +) (p values < 0.05). At a median follow-up of 58months, the 5-year overall survival rate of non-metastatic patients was 86.6%. Multivariate analysis showed N + to be the most significant prognostic factor (HR = 3.3; 95%CI 1.5-7.1), followed by T-stage (HR = 2.9; 95%CI 1.4-6.3), HER2 + (HR = 2.5; 95%CI 1.2-5.3) and MMC subtype (HR = 1.9; 95%CI 1.0-3.9). Poor prognostic factors of MBC include high T-stage, N-positivity, HER2 overexpression and MMC subtype. Given the low response rate to neoadjuvant CT, upfront surgery is appropriate for MBC patients.

The 5-year relative survival rate among cancer patients in Henan province of China, 2015-2019

Objective: To analyze the 5-year relative survival rate of cancer in Henan province based on cancer registration data. Methods: Cancer survival data were extracted from the cancer registration database of Henan province with the diagnosis date between January 1, 2010 and December 31, 2019 were included. The closing date of follow-up was set as December 31, 2019. The 5-year relative survival rate of cancer was calculated using the period survival analysis method and the Ederer II method in the R package "periodR", and the interest period was between 2015 and 2019. Results: During the period of 2015-2019, the overall 5-year relative survival rate of cancer patients in Henan province was 43.6%, and after age-standardization, it was 40.2%. The overall 5-year relative survival rate showed the characteristics of higher survival rate in females than males (45.9% vs 34.7%, Z=39.60, P＜0.001) and higher survival rate in urban areas than rural areas (44.9% vs 39.1%, Z=12.97, P＜0.001). The 5-year relative survival rate for cancer patients among children aged 0-14 was 60.2%, and for adults aged 15 and above, it was 43.5%, which was standardized to 40.2% after age adjustment. There are two types of cancers with a standardized 5-year relative survival rate exceeding 70% (thyroid cancer at 82.2% and breast cancer at 71.6%), and four cancers with a rate below 30% (pancreatic cancer at 18.2%, liver cancer at 19.6%, lung cancer at 24.0%, and gallbladder cancer at 26.6%). Conclusion: The cancer 5-year survival rate in Henan Province is lower than that of the national average, indicating the need for continued enhancement of cancer prevention and control measures.

Clinical study on conversion therapy of hepatocellular carcinoma - summary and comparison of clinical data from a single center of consecutive four years

AimThe purpose of this study was to interpret real-world clinical data to analyze the surgical safety and survival outcomes of patients with initial unresectable hepatocellular carcinoma (uHCC) after conversion therapy.MethodsA retrospective analysis was performed on 2984 hepatocellular carcinoma (HCC) patients hospitalized in Shandong Cancer Hospital Affiliated to Shandong First Medical University from June 1st, 2019 to June 1st, 2023. Clinicopathological features, response to systemic and/or loco-regional treatments, surgical resection rate after conversion therapy, surgical safety, and postoperative recurrence were analyzed.ResultsA total of 38 patients were successfully converted to obtain surgical resection. 35 patients underwent radical resection. A high objective response rate (ORR) (52.6% under RECIST v1.1 and 78.9% under mRECIST criteria) was observed in patients under conversion therapy, and the disease control rate (DCR) was 100%. Pathologic complete response (pCR) was 42.9%. Treatment-related adverse events (TRAEs) of any grade were observed in 37 patients (97.4%). Safety of conversion or direct surgery continues to improve. The median follow-up time was 19.3 months. The 1-year Disease-free survival (DFS) rate of patients with direct surgery and patients with conversion surgery were 91.4% and 86.8%, respectively.ConclusionsWith conversion therapy, a small percentage (1.81%) of uHCC patients are likely to be converted to radical resection. Local combined systemic therapy is a relatively safe and effective conversion therapy, and the safety of surgery is gradually improved after successful conversion. Preliminary follow-up data showed satisfactory survival benefits for patients undergoing conversion surgery.Trial registrationThis was a retrospective study and it did not interfere with treatment decisions.

SURGICAL TREATMENT OF RECTAL CANCER WITH PRESERVATION OF THE LEFT COLIC ARTERY AND ICG NAVIGATION

Goal. To analyze the peculiarities of surgical diagnosis of lymphogenic metastasis in patients with colorectal cancer. Generalization of data from Ukrainian and foreign literature, results of randomized studies and meta-analyses. The study is based on the results of observation of 88 patients with colorectal cancer (CRC) of the prospective study group. To analyze the features of surgical diagnostics of lymphogenic metastasis in patients with colorectal cancer. Materials and methods. The results of surgical treatment of 88 patients with rectal cancer were analyzed and systematized. These patients underwent examination and treatment in 2023-2024 at the "Prykarpattian Clinical Oncology Center of the Ivano-Frankivsk Regional Council." The study included patients with stage II-III colorectal cancer (T2-3N0-2M0) without complicated courses. All patients received treatment based on NCCN recommendations. Surgical treatment was performed in standard volume with the removal of all regional lymph node groups and preservation of the left colic artery using real-time lymph node mapping with indocyanine green. All patients were divided into two study groups: Group I included 45 patients who underwent anterior or low anterior resection of the rectum with preservation of the left colic artery. This group was subdivided into two subgroups: Ia – 13 patients who underwent intraoperative indocyanine green injection for real-time lymph node visualization. Ib – 32 patients who did not receive this drug but underwent the same volume of surgery. Group II consisted of 43 patients who underwent anterior or low anterior resection of the rectum with high ligation of the inferior mesenteric artery. This group served as the control group. Results. The main mechanisms of lymphogenic metastasis in colorectal cancer patients in Ivano-Frankivsk were characterized. Literature data on the features of surgical diagnostics of colorectal cancer metastasis were summarized. A review of literature shows the social significance of these studies, as this pathology often leads to patient disability, requiring surgical interventions and further palliative treatment due to the widespread metastasis associated with this disease. The priority task for researchers remains the search for the most effective treatment methods for this pathology, based on randomized studies of colorectal cancer treatment and international protocols. According to the literature, surgical treatment of colorectal cancer remains insufficiently effective at the current stage of oncology. Modern methods offer low 5-year survival rates, emphasizing the need to study factors for individualized treatment. The overall 5-year survival rate for colorectal cancer patients from 2018-2022 was (45.8±2.3)%. The effectiveness of using real-time ICG navigation for lymph node mapping and preservation of the left colic artery in stage II-III (T2-4N1-2M0) rectal cancer patients has been proven. This technique allows for optimal lymphadenectomy, reducing the frequency of surgical complications by 14.7% (p&lt;0.05). Conclusion. Ensuring radical resection of rectal cancer while maximizing blood supply preservation to the anastomosis is the main goal of colorectal surgeons. Over the past two decades, surgical techniques have significantly improved due to advancements in surgical equipment. It is anticipated that surgical technologies will further evolve towards enhancement and individualization in the future. Our procedure serves as an example of modern and personalized rectal cancer surgery.

Optimal transplant strategy of pediatric liver transplantation for fibropolycystic liver disease: Multicenter retrospective study in Japan.

To assess the preoperative disease characteristics and indications for living donor liver transplantation (LDLT), complications, patient survival, and prognosis after LDLT for fibropolycystic liver disease (FLD) in children. We undertook a cross-sectional survey of patients who underwent LDLT for FLD between January 2002 and December 2020. A total of 35 patients (22 male and 13 female individuals) with FLD were included in this study, of whom 19 (54.3%) had isolated congenital hepatic fibrosis and 16 (45.6%) had Caroli syndrome. Refractory gastrointestinal bleeding was the most frequent symptom related to the indication for LDLT, being found in 48.6% of our patients, followed by uncontrollable cholangitis and ascites. The median age at the time of LDLT was 8.1years old. Of the 27 patients presenting with renal involvement, 13 patients required kidney transplantation (KT). Overall, the renal function after LDLT decreased regardless of renal involvement; however, patients with renal involvement had a significantly lower estimated glomerular filtration rate than those without renal involvement throughout the course of this study (p<0.01). The 5-year overall patient survival rate was 97.1%. Two patients died with a median follow-up of 8.9years after LDLT; one died due to sepsis 2weeks after simultaneous liver-kidney transplantation and the other committed suicide 10years after LDLT. The prognosis of the pediatric patients who underwent LDLT for FLD was excellent. However, an individualized treatment approach based on the status of the renal function and liver disease is important, as a certain proportion of patients require KT.

High BMI Is Associated with Changes in Peritumor Breast Adipose Tissue That Increase the Invasive Activity of Triple-Negative Breast Cancer Cells

Breast cancer is the most common cancer in women with multiple risk factors including smoking, genetics, environmental factors, and obesity. Smoking and obesity are the top two risk factors for the development of breast cancer. The effect of obesity on adipose tissue mediates the pathogenesis of breast cancer in the context of obesity. Triple-negative breast cancer (TNBC) is a breast cancer subtype within which the cells lack estrogen, progesterone, and HER2 receptors. TNBC is the deadliest breast cancer subtype. The 5-year survival rates for patients with TNBC are 8–16% lower than the 5-year survival rates for patients with estrogen-receptor-positive breast tumors. In addition, TNBC patients have early relapse rates (3–5 years after diagnosis). Obesity is associated with an increased risk for TNBC, larger TNBC tumors, and increased breast cancer metastasis compared with lean women. Thus, novel therapeutic approaches are warranted to treat TNBC in the context of obesity. In this paper, we show that peritumor breast adipose-derived secretome (ADS) from patients with a high (&gt;30) BMI is a stronger inducer of TNBC cell invasiveness and JAG1 expression than peritumor breast ADS from patients with low (&lt;30) BMI. These findings indicate that patient BMI-associated changes in peritumor AT induce changes in peritumor ADS, which in turn acts on TNBC cells to stimulate JAG1 expression and cancer cell invasiveness.

Tailoring Escalation Adjuvant Therapy for Early-Stage Triple-Negative Breast Cancer in the CBCSG010 Clinical Trial Biomarker Analysis.

Triple-negative breast cancer (TNBC) is a highly heterogeneous disease. The CBCSG010 trial is a prospective and multicenter phase III clinical trial confirming that adding adjuvant capecitabine significantly improved the 5-year disease-free survival (DFS) rate in patients with TNBC by 5.9%. In this study, we attempted to identify the specific population that benefited from adjuvant therapy. In this retrospective exploratory analysis, we performed RNA sequencing of tumor tissues from patients with TNBC in the CBCSG010 clinical trial. A single-sample gene set enrichment analysis algorithm and survival analysis were performed to characterize the intrinsic molecular features of the TNBC microenvironment and assess the associations between immune-related gene expression levels or immune cell counts with capecitabine treatment efficacy. Additionally, we performed immunohistochemical staining of 2 markers, PD-L1 and CD8, and hematoxylin-eosin staining of stromal tumor-infiltrating lymphocytes (sTILs) on formalin-fixed, paraffin-embedded specimens to validate findings from bioinformatics analyses. We found that patients with TNBC with high immune-infiltration treated with capecitabine were more likely to have a better prognosis. We used a cutoff of ≥25 combined positive score (CPS) of PD-L1, ≥10% positive sTILs, and ≥10% positive cells of CD8 to define the "immune-hot" patients. Among immune-hot patients, Kaplan-Meier curves showed that 5-year DFS rates were 96.9% and 79.4% in the capecitabine and control groups, respectively (hazard ratio, 0.13; 95% CI, 0.03-0.52; P=.049 in favor of capecitabine). In the capecitabine group, the 5-year DFS rate was higher for immune-hot patients than for immune-cold patients (96.9% vs 76.4%; hazard ratio, 0.11; 95% CI, 0.04-0.29; P=.028). Our study suggested that immune-hot patients with TNBC are more likely to benefit from adjuvant capecitabine, and that combining immunotherapy with chemotherapy may be expected to be more effective in immune-hot patients.

Acceptable outcomes of liver transplantation in uninsured patients under the coverage of a state assistance program.

The lack of health insurance is a major barrier in the access to healthcare even in case of life-saving procedures such as liver transplantation (LT). Concerns about worse outcomes in uninsured patients have also discouraged the evaluation and transplantation of patients without adequate health insurance coverage. The aim of this study is to evaluate outcomes from the largest cohort of uninsured patients who underwent LT with the support of a state payment assistance program (also called charity care). This study included all consecutive patients who underwent LT at a single center from 2002 to 2020. Demographic, clinical, social variables and outcome metrics were collected and compared between insured and uninsured patients. Among a total of 978 LT recipients, 594 had private insurance, 324 government insurance (Medicare/Medicaid), 60 were uninsured and covered under a state charity care program. In the charity care group, there was a higher proportion of Hispanic subjects, single marital status, younger age, and high-MELD score patients. The 1- and 3-year patient survival rates were 89.0% and 81.8% in private insurance patients, 88.8% and 80.1% in government insurance recipients, and 93.3% and 79.6% in those with charity care (p=0.49). There was no difference in graft survival between insured and uninsured patients (p=0.62). The three insurance groups presented similar hospital length-of-stay and 30-day readmission rates. In both univariate and multivariate analysis, uninsured status (charity care) was not associated with worse patient survival (HR:1.23, 95%CI: 0.84-1.80, p=0.29) or graft survival (HR:1.22, 95%CI:0.84-1.78, p=0.29). In conclusion, there was no difference in outcomes after LT between insured and uninsured patients. A charity care program may be an effective tool to mitigate socio-economic disparities in both outcomes and access to LT.

Failure to Rescue Pediatric Recipients of Living Donor Liver Transplantation: A Single-Center Study of Technical Complications in 500 Primary Grafts.

The concept of failure to rescue (FTR) has been used to evaluate the quality of care in several surgical specialties but has not been well-studied after living donor liver transplantation (LDLT) in children. This study retrospectively reviewed 500 pediatric LDLT performed at a single center between 1993 and 2022. The recipient outcomes were assessed by means of patient and graft survival rates, retransplantation rates, and arterial/portal/biliary complication rates. Graft and patient losses secondary to these complications were calculated regarding FTR for patients (FTRp) and grafts (FTRg). Overall 1- and 5-year patient survival rates were 94.5% and 92.1%, respectively, the corresponding figures for graft survival being 92.7% and 89.8%. One-year hepatic artery complication rate was 3.6% (n = 18 cases), the respective rates for portal vein complications and biliary complications being 5.7% (n = 57) and 15.6% (n = 101). One-year FTRp rates for hepatic artery thrombosis, portal vein thrombosis, anastomotic biliary stricture, and intrahepatic biliary stricture were 28.6%, 9.4%, 3.6%, and 0%, respectively. The corresponding FTRg rates being 21.4%, 6.3%, 0%, and 36.4%. Such novel analytical method may offer valuable insights for optimizing quality of care in pediatric LDLT.

A Five-Year Survival Analysis of Patients with Gastric Cancer in Kerman Province

Purpose: Gastric Adenocarcinoma (GAC) is the second most frequent cause of cancer-related deaths worldwide. Determining survival and its associated prognostic factors provides a basis for further interventions to prolong survival among patients with GAC. In this study, we aimed to perform a 5-year survival analysis among GAC patients in Kerman, Iran. Materials and Methods: This retrospective multi-centric study was conducted on all patients with GAC who were referred to Afzalipour, Bahonar, and Shafa Hospitals in Kerman, Iran in 2009-2019. The 5-year survival rates were calculated based on prognostic factors, including age, histopathology, stage/grade of the tumor, metastatic status, and surgical procedures using the Kaplan-Meier analysis and log-rank test. Results: The 5-year survival rate of GAC patients with total gastrectomy was higher than those with subtotal gastrectomy (P = 0.03). Also, the 5-year survival rate was substantially improved after lymph node dissection (P &lt; 0.001). Overall survival has not been significantly different in terms of age, sex, grade, histological type, clinical T stage, lymphovascular invasion, and perineural invasion. Conclusion: Overall survival was different for the two surgical procedures and lymph node dissection. Therefore, total gastrectomy and lymph node dissection are significant independent prognostic factors for overall survival in patients with GAC.

Staging of early-stage lung cancer without routine PET in candidates for segmentectomy.

We aimed to investigate the accuracy of clinical staging without the routine use of PET/CT in cIA1 and cIA2 NSCLC scheduled for segmentectomy. 305 consecutive segmentectomies were retrospectively analyzed. Overall survival was calculated using the Kaplan-Meier method. Logistic regression was performed to investigate factors independently associated with pathologic upstaging. UICC-upstaging was found in 86 patients (28%). Upstaged patients had longer operative times (146 ± 46 vs. 131 ± 44 minutes, p= 0.009), a higher number of lymph nodes removed (17 ± 10 vs. 13 ± 8, p= 0.001), and a higher rate of L1 involvement (34% vs. 16%, p< 0.001) than non-upstaged patients. N1 was found in 10 patients (3%) and N2 in 13 patients (4%). Nodal positive patients had longer operation times (154 ± 50 vs. 133 ± 44 minutes, p= 0.031), higher rates of R1 (9% vs. 1%, p= 0.006) and L1 (39% vs. 20%, p< 0.026) than patients without nodal involvement. The 3-year and 5-year overall survival rates for upstaged and non-upstaged patients were 67% and 54%, and 85% and 67%, respectively (p = 0.040). In logistic regression L1 involvement (OR 2.394, p= 0.005) and the number of dissected lymph nodes (OR 1.037, p= 0.016) were independently associated with upstaging. Patients who received PET as part of clinical staging did not have significantly lower nodal upstaging. Selective use of PET/CT based on the results of computed tomography may be a viable option for patients with proven or suspected NSCLC up to 2 cm.

Impact of Medicaid expansion on kidney transplantation in the State Oklahoma.

There is no data evaluating the impact of Medicaid expansion on kidney transplants (KT) in Oklahoma. To investigate the impact of Medicaid expansion on KT patients in Oklahoma. The UNOS database was utilized to evaluate data pertaining to adult KT recipients in Oklahoma in the pre-and post-Medicaid eras. Bivariate analysis, Kaplan Meier analysis was used to estimate, and cox proportional models were utilized. There were 2758 pre- and 141 recipients in the post-Medicaid expansion era. Post-expansion patients were more often non-United States citizens (2.3% vs 5.7%), American Indian, Alaskan, or Pacific Islander (7.8% vs 9.2%), Hispanic (7.4% vs 12.8%), or Asian (2.5% vs 8.5%) (P < 0.0001). Waitlist time was shorter in the post-expansion era (410 vs 253 d) (P = 0.0011). Living donor rates, pre-emptive transplants, re-do transplants, delayed graft function rates, kidney donor profile index values, panel reactive antibodies levels, and insurance types were similar. Patients with public insurance were more frail. Despite increased early (< 6 months) rejection rates, 1-year patient and graft survival were similar. In Cox proportional hazards model, male sex, American Indian, Alaskan or Pacific Islander race, public insurance, and frailty category were independent risk factors for death at 1 year. Medicaid expansion was not associated with graft failure or patient survival (adjusted hazard ratio: 1.07; 95%CI: 0.26-4.41). Medicaid expansion in Oklahoma is associated with increased KT access for non-White/non-Black and non-United States citizen patients with shorter wait times. 1-year graft and patient survival rates were similar before and after expansion. Medicaid expansion itself was not independently associated with graft or patient survival outcomes. Ongoing research is necessary to determine the long-term effects of Medicaid expansion.

Histopathological Growth Patterns Determine the Outcomes of Colorectal Cancer Liver Metastasis Following Liver Resection.

Colorectal cancer liver metastasis (CRCLM) remains a lethal diagnosis, with an overall 5-year survival rate of 5-10%. Two distinct histopathological growth patterns (HGPs) of CRCLM are known to have significantly differing rates of patient survival and response to treatment. We set out to review the results of 275 patients who underwent liver resection for CRCLM at the McGill University Health Center (MUHC) and analyze their clinical outcome, mutational burden, and pattern of cancer progression in light of their HGPs, and to consider their potential effect on surgical decision making. We performed a retrospective multivariate analysis on clinical data from patients with CRCLM (n = 275) who underwent liver resection at the McGill University Health Center (MUHC). All tumors were scored using international consensus guidelines by pathologists trained in HGP scoring. A total of 109 patients (42.2%) were classified as desmoplastic and angiogenic, whereas 149 patients (57.7%) were non-desmoplastic and vessel co-opting. The 5-year survival rates for angiogenic patients compared with vessel co-opting patients were 47.1% and 13%, respectively (p < 0.0001). Multivariate analysis showed patients with vessel co-opting CRCLM had a higher incidence of extrahepatic metastatic disease (p = 0.0215) compared with angiogenic CRCLM. Additionally, KRAS mutation status was a marker of increased likelihood of disease recurrence (p = 0.0434), as was increased number of liver tumors (p = 0.0071) and multiple sites of extrahepatic metastatic disease (p < 0.0001). Multivariate analysis identified key clinical prognostic and molecular features correlating with the two HGPs. Determining liver tumor HGPs is essential for patient prognostication and treatment optimization.

Differences in characteristics and outcomes between early-onset colorectal cancer and late-onset colorectal cancers

IntroductionColorectal cancer (CRC) represents a significant health burden worldwide, with a notable increase in early-onset colorectal cancer (EOCRC) cases, defined as those diagnosed before the age of 50 years. Materials and methodsUsing data from Taiwan's national cancer registry and a retrospective cohort from Chang Gung Memorial Hospital, this study analyzed CRC cases diagnosed between 2008 and 2019. The analysis compared the EOCRC and late-onset CRC (LOCRC) groups in terms of clinicopathological characteristics, pre-diagnostic symptoms, and survival outcomes. ResultsThe analysis revealed a continuous increase in the annual incidence of EOCRC, with colon cancer and rectal cancer rising by 3.2 % and 3.3 %, respectively. Patients with EOCRC presented with more aggressive disease characteristics, such as signet-ring cell adenocarcinoma, mucinous adenocarcinoma, and poorly differentiated grade. Advanced stages at diagnosis, stages III and IV, were more common with EOCRC (62.4 %) than with LOCRC (50.3 %). Patients with EOCRC reported rectal bleeding, changes in bowel habits, and abdominal pain more frequently than those in the LOCRC group. There is a strong association between stool-related symptoms and left-sided CRC. Despite similar surgical outcomes, the 5-year cancer-specific survival rate of patients with stage IV EOCRC was significantly lower than that of patients with LOCRC (32.8 % vs. 51.9 %, p = 0.012). ConclusionThis study highlights a persistent rise in the incidence of EOCRC, with patients presenting with more aggressive disease and experiencing inferior survival. These findings underscore the importance of heightened awareness and early detection strategies for CRC, especially in younger populations, to improve the prognosis.

Narrative review of research progress of RNA m5C methylation in head and neck malignancies.

Head and neck malignancies encompass a spectrum of malignant tumors occurring in the head and neck region, characterized by rapid progression, high recurrence rates, and dismal prognoses. Despite significant advancements in comprehensive surgery-based therapies, the 5-year survival rate for patients has not shown substantial improvement. There is an urgent need to investigate novel targeted therapies. With the advancements in epigenetics, RNA 5-methylcytosine (m5C) methylation, a prevalent form of RNA modification, has been identified by numerous studies as playing a pivotal role in the pathological processes of tumorigenesis and development. However, a comprehensive review within the realm of head and neck malignancies is currently lacking. This study aims to comprehensively review the biological implications of RNA m5C methylation regulators in the pathogenesis and progression of various systemic malignant tumors, with a specific focus on exploring the potential impact of RNA m5C methylation on head and neck malignancies. A literature search on RNA m5C methylation and head and neck malignancies was conducted using PubMed, resulting in the inclusion of 46 relevant articles. The Cancer Genome Atlas (TCGA) database was utilized to analyze the correlation between m5C regulatory factors and clinicopathological features in patients with head and neck squamous cell carcinoma (HNSCC). Aberrant expression of RNA m5C methylation regulators is observed in head and neck malignancies, displaying a correlation with the clinicopathological grading of tumors. RNA m5C methylation may contribute to the progression of head and neck malignancies and could be associated with an unfavorable prognosis for patients. These findings offer valuable insights for the development of targeted treatments for head and neck malignancies.

Astragalus Injection Enhances the Sensitivity of Clinical Cancer Patients to Chemotherapy: A Systematic meta-Analysis

Background Traditional Chinese Medicine Astragalus was commonly used to assist chemo-drug treatment in clinical cancer patients. However, whether Astragalus injection (AGI) reverses drug resistance remains unclear. Therefore, a meta-analysis is necessary to assess the effect of AGI on resistance reversement in cancer patients. Method The studies presenting tumor response rates in cancer patients receiving chemo-drugs treatment in combination with AGI were systematically searched from six common scientific databases until February 2024. The relative risks (RRs) indicating the tumor response rate, 1-year survival rate, and quality of life improvement in clinical patients among two groups were calculated in metan package. The pooled RRs with 95% confidence intervals (CIs) were used to explore the effect of AGI on enhancing drug sensitivity in terms of tumor response, 1-year survival rate and quality of life improvement in cancer patients. Result Fifty-one studies were included for meta-analysis following a thorough screening process that adhered to the inclusion and exclusion criteria. A total of 4613 patients were enrolled in all included trials. Results obtained indicated that AGI significantly enhanced the sensitivity of cancers to chemo-drugs with pooled RRs (95% CI) of 1.25 (1.18, 1.32), prolonged the 1-year survival rate of patients with pooled RRs (95% CI) of 1.34 (1.14, 1.57), improved the quality of life with pooled RRs (95% CI) of 1.61 (1.34, 1.93). Similarly, Astragalus's main component, astragaloside polysaccharides (APS), also enhances drug sensitivity in clinical cancer patients. Conclusion Our findings demonstrated that AGI had the ability to resensitize cancers to chemo-drugs and improve the quality of life of cancer patients. Therefore, AGI could potentially be used as a drug resistance reversal for resistant cancer treatment.

Clinicopathologic features and surgery-related outcomes of duodenal adenocarcinoma: A multicenter retrospective study

BackgroundThe incidence of duodenal adenocarcinoma is increasing, with limited studies on this disease published. This multicenter retrospective study aimed to analyze the clinicopathologic features of duodenal adenocarcinoma and identify prognostic factors for postoperative survival. MethodsDemographic characteristics, clinicopathologic features, treatment outcomes, and survival of patients with duodenal adenocarcinoma undergoing surgical treatment at 16 Chinese medical centers from 2012 to 2023 were retrospectively analyzed. ResultsAmong the 2,189 patients with duodenal adenocarcinoma included, 50.07% had extra-ampullary duodenal adenocarcinoma and 49.93% had peri-ampullary duodenal adenocarcinoma. The 1-, 3-, and 5-year overall survival rates for patients who underwent radical surgery were 91.78%, 69.30%, and 55.86%, respectively. The median overall survival was 73 months (range, 64–84), and the median progression-free survival was 64 months (range, 52–76). No differences in survival were observed between the laparotomy and minimally invasive surgery groups (log-rank P = .562); furthermore, no significant between-group differences in operation time, lymph node dissection, postoperative complications, or in-hospital mortality were observed (P > .05). The minimally invasive surgery group experienced less intraoperative blood loss (250 mL vs 100 mL, P < .001), fewer intraoperative blood transfusions (24.97% vs 18.84%, P = .002), and shorter hospital stays (28 days vs 23 days, P < .001). Multivariate Cox regression analysis revealed that advanced age, advanced stage, longer operation time, intraoperative blood transfusion, and postoperative hemorrhage were independent risk factors for poor prognosis. ConclusionRadical surgery was associated with favorable overall survival among patients with duodenal adenocarcinoma, and no difference in survival was observed between patients with extra-ampullary duodenal adenocarcinoma and peri-ampullary duodenal adenocarcinoma. Minimally invasive surgery is a reliable alternative for duodenal adenocarcinoma treatment.

Clinical treatment strategy and follow-up of lymphoepithelioma-like carcinoma: a retrospective study.

Aim: To investigate the clinical features, diagnosis and treatment of lymphoepithelioma-like carcinoma (LELC).Materials & methods: The clinical data of 114 LELC patients were retrospectively analyzed.Results: Ninety-eight patients (86.0%) were Epstein-Barr virus-encoded small RNA (EBER) positive detected by situ hybridization. A 67.1% (51/76) patients had PD-L1 expression. The 5-year overall survival rate of EBER negative patients was 51.6% while the rate of positive patients was 84.8% (p=0.015). The 5-year progression free survival rate of EBER negative patients was 40.2% while the rate of positive patients was 70.2% (p=0.004).Conclusion: The progression of LELC is relatively slow and present a better prognosis. The occurrence of tumor is closely related to Epstein-Barr virus infection and PD-L1 is highly expressed in tumor cells.

A case report of high-grade intraepithelial neoplasia of the bronchial mucosa

BackgroundLung cancer is the most common cause of cancer death worldwide and poses an immediate health threat. Despite decades of basic and clinical research, the 5-year survival rate for lung cancer patients is less than 10%.The most important drawbacks in efficient treatment of lung cancer are delayed diagnosis and absence of effective screening. Detection and study of precancerous lesions of the bronchial mucosa might be one of the turning points in understanding of neoplastic transformation. Therefore, it would be the most effective prevention and early treatment modality. We report a case of high-grade intraepithelial neoplasia of the bronchial mucosa in which a neoplastic growth in the lumen of intrinsic segment in the upper lobe of the left lung was detected on electronic bronchoscopy, and biopsy confirmed squamous papillary hyperplasia with high-grade intraepithelial neoplasia.Case presentationA 74-year-old male was admitted to the hospital due to a mass lesion in his left lung. After admission, computed tomography scan of the chest showed an intraluminal mass in the intrinsic segment of the upper lobe of the left lung and an enlarged left hilum.ConclusionsHigh-grade intraepithelial neoplasia of the bronchial mucosa is rare in the respiratory system. We report a case that can provide useful information for early diagnosis and treatment of the disease.
