UNASSIGNED: The postoperative survival rates of patients with gastric cancer at different stages treated at the National Cancer Center (NCC) of China have not been reported. Therefore, we evaluated the survival of patients with gastric cancer who underwent surgery at the NCC from 2011 to 2018 to provide baseline information for further studies.
UNASSIGNED: We identified 7,301 patients with primary gastric carcinoma who underwent surgery at the NCC between January 2011 and May 2018; among these, 5,008 patients were enrolled in this study. Follow up was completed on April 30, 2020. We analyzed the 5-year survival according to the stage, sex, age, and other clinicopathological features.
UNASSIGNED: Five-year survival rates of patients with pTNM stages IA, IB, IIA, IIB, IIIA, IIIB, IIIC, and IV treated at the NCC were 94.9%, 91.8%, 86.5%, 76.1%, 61.1%, 44.2%, 29.7%, and 8.1%, respectively, which were similar to those reported in Japan during the same period. Five-year survival rates of patients with ypTNM stages I, II, III, and IV were 93.1%, 63.2%, 27.2%, and 0.0%, respectively. In multivariable analysis, age, signet ring cell carcinoma, adjuvant chemotherapy, and degree of differentiation were revealed as important prognostic factors.
UNASSIGNED: The survival rates of patients with gastric cancer treated at the NCC have been significantly improved, reaching the levels of Japan in the same period.

UNASSIGNED: Breast cancer is a severe life-threatening condition in which many women are involved yearly. One factor that has recently been noticed and investigated as a diagnostic predictor of this type of cancer is the number of tumor buds and the relation of this factor with a patient\'s survival rate.
UNASSIGNED: This study includes 150 female patients over 18 years old with a mean age of 53.99 ± 12.56 years old with breast cancer, which was diagnosed at various medical centers, including Rouhani Hospital itself, and referred to Rouhani Hospital Medical Center, Babol, Iran. The number of intratumoral and peritumoral buds in patients\' microscopic slides were archived and evaluated along with tumor microenvironment on hematoxylin and eosin (H&E) slides and compared to other clinicopathological findings. This article precisely investigated the relationship between the number of intratumoral and peritumoral buds with patients\' 5-year survival rate. Also, the relationship between age, tumor stage, grade, size, the number of lymph nodes involved, and the presence of metastasis with the number of intratumoral and peritumoral buds was studied.
UNASSIGNED: The result showed a significant statistical association between the number of intratumoral and peritumoral buds with tumor size, tumor stage, presence of metastasis, the number of lymph nodes involved, and 5-year survival rate. On the other hand, there is not a significant statistical association between the number of intratumoral and peritumoral buds with age and tumor grade.
UNASSIGNED: Our investigation revealed a significant statistical relationship between the number of tumor buds and patients\' survival rate. So, this factor should be considered significant to help those patients increase their survival ratio.

OBJECTIVE: This single center retrospective study aimed to investigate the factors associated with central nervous system (CNS) involvement of primary vitreoretinal lymphoma (PVRL).
METHODS: Clinical features of patients with PVRL (Group 1), those diagnosed with vitreoretinal lymphoma (VRL) after primary CNS lymphoma diagnosis (Group 2), and those concurrently diagnosed with CNS lymphoma and VRL (Group 3), were compared. The main outcomes included sex, age, types of treatment, survival, visual acuity, diagnostic methods, VRL recurrence, ocular manifestations, and interleukin levels in the aqueous humor.
RESULTS: Groups 1, 2, and 3 included 66 eyes in 38 patients, 29 eyes in 18 patients, and 14 eyes in 8 patients, respectively. Group 3 had shorter overall survival (OS) than Groups 1 and 2 (P = 0.042 and P = 0.009, respectively). The three groups did not differ in progression-free survival (P = 0.060). The 5-year survival rates of Groups 1, 2, and 3 were 56.5%, 44.0%, and 25.0%, respectively (P = 0.001). Patients with CNS involvement in Group 1 exhibited VRL recurrence (P < 0.001), high interleukin-10 (P = 0.024), and sub-retinal pigment epithelium (RPE) infiltration (P = 0.009). Patients experiencing VRL recurrence in Group 1 tended to show CNS involvement (P < 0.001).
CONCLUSIONS: Patients concurrently diagnosed with CNS lymphoma and VRL had a shorter OS and a lower 5-year survival rate. In patients with PVRL, the recurrence of VRL, high interleukin-10, and sub-RPE infiltration were associated with CNS involvement.

(1) Background: Colorectal cancer (CRC) is the third most common cancer in terms of incidence and mortality. Approximately 90% of all colorectal cancer cases are adenocarcinomas, originating from epithelial cells of the colorectal mucosa. Upregulated gene 4 (URG4) is an oncogene involved in cancer development. The aim of the study was to assess the immunohistochemical expression of URG4 protein expression in Polish patients with colon adenocarcinoma who were not treated with any therapy before radical surgery. (2) Methods: The study used colon tissue samples taken from people with a confirmed diagnosis of colorectal adenocarcinoma after a thorough histopathological examination. The associations between the immunohistochemical expression of URG4 and clinical parameters were analyzed by the Chi2 test or Chi2Yatesa test. The study conducted an analysis of the correlation between the expression of URG4 and the five-year survival rate of patients through the application of the Kaplan-Meier analysis and the log-rank statistical test. The intracellular localization of URG4 was identified through the utilization of transmission electron microscopy (TEM) methodology. (3) Results: In univariate Cox regression analyses, immuno-histochemical expression of URG4, grade of histological differentiation, depth of invasion, angioinvasion, PCNA expression, stage of disease and lymph node involvement were found to be significant prognostic factors. Within our patient cohort, it was observed that the degree of tumour differentiation and URG4 expression were found to be distinct prognostic factors in regard to the 5-year survival rates of those with colon adenocarcinoma. (4) Conclusions: High immunohistochemical expression of URG4 correlates with poor prognosis in patients with colon adenocarcinoma.

The Notch signalling pathway is one of the most conserved and well-characterised pathways involved in cell fate decisions and the development of many diseases, including cancer. Among them, it is worth noting the Notch4 receptor and its clinical application, which may have prognostic value in patients with colon adenocarcinoma. The study was performed on 129 colon adenocarcinomas. Immunohistochemical and fluorescence expression of Notch4 was performed using the Notch4 antibody. The associations between the IHC expression of Notch4 and clinical parameters were analysed using the Chi2 test or Chi2Yatesa test. The Kaplan-Meier analysis and the log-rank test were used to verify the relationship between the intensity of Notch4 expression and the 5-year survival rate of patients. Intracellular localisation of Notch4 was detected by the use of the immunogold labelling method and TEM. 101 (78.29%) samples had strong Notch4 protein expression, and 28 (21.71%) samples were characterised by low expression. The high expression of Notch4 was clearly correlated with the histological grade of the tumour (p < 0.001), PCNA immunohistochemical expression (p < 0.001), depth of invasion (p < 0.001) and angioinvasion (p < 0.001). We can conclude that high expression of Notch4 is correlated with poor prognosis of colon adenocarcinoma patients (log-rank, p < 0.001).

The Apoptotic protease activating factor 1 (Apaf-1) protein, as one of the factors involved in the activation of the mitochondrial apoptotic pathway, plays an important role in cancer biology. Apaf-1 expression in tumour cells has been shown to be downregulated, with significant implications for tumour progression. Hence, we investigated the expression of Apaf-1 protein in the Polish population of patients with colon adenocarcinoma without any therapy prior to radical surgery. Moreover, we assessed the relation between Apaf-1 protein expression and the clinicopathological factors. The prognostic activity of this protein was analyzed in relation to 5-year survival of patients. In order to show the localization of Apaf-1 protein at the cellular level, the immunogold labelling method was used.
The study was conducted using the colon tissue material from patients with histopathologically confirmed colon adenocarcinoma. Immunohistochemical expression of Apaf-1 protein was performed using Apaf-1 antibody at dilution 1:600. The associations between the immunohistochemistry (IHC) expression of Apaf-1 and clinical parameters were analyzed using the Chi2 test and Chi2Yatesa test. Kaplan-Meier analysis and the log-rank test were used to verify the relationship between the intensity of Apaf-1 expression and 5-year survival rate of patients. The results were considered statistically significant when p < 0.05.
Apaf-1 expression was evaluated by immunohistochemical staining in whole tissue sections. Thirty-nine (33.23%) samples had strong Apaf-1 protein expression and 82 (67.77%) samples were characterized by low expression. The high expression of Apaf-1 was clearly correlated with the histological grade of the tumour (p = 0.001), proliferating cell nuclear antigen (PCNA) immunohistochemical expression (p = 0.005), age (p = 0.015), depth of invasion (p < 0.001) and angioinvasion (p < 0.001). The 5-year survival rate was significantly higher in the group of patients with high expression of this protein (log-rank, p < 0.001).
We can conclude that Apaf-1 expression is positively correlated with reduced survival of colon adenocarcinoma patients.

Primary gastric squamous cell carcinoma (GSCC) is an extremely rare malignancy with a poor prognosis. Despite the improved knowledge regarding its pathogenesis and biology, the treatment options remain limited. The present study reported on the unique case of a mismatch repair-deficient (dMMR) primary GSCC in a 79-year-old woman reporting fatigue and symptoms of upper gastrointestinal tract bleeding. Physical examination revealed abdominal pain at palpation. Gastroscopy revealed a large, exophytic, bleeding tumor. Medical imaging confirmed a mushroom-like polyp in the lumen of the stomach, with no signs of disease spread. Total gastrectomy and D2 lymphadenectomy were performed. Pathological examination of the post-operational material confirmed a well-differentiated SCC invading the mucosa, submucosa and muscle layer. There were no signs of dissemination observed in any of the 32 excised lymph nodes. Notably, according to the last follow-up, the patient remains well, supporting the 5-year GSCC survival rate statistics. To the best of our knowledge, this is the first such GSCC case reported in the Surgical Oncology Outpatient Clinic (Copernicus Memorial Hospital, Lodz, Poland) and these findings add to the limited data on GSCC. Although this is a very rare condition, it should always be considered during the process of diagnosis of gastric tumors.

UNASSIGNED: Promoter hypermethylation of tumor suppressor genes presents promising markers for lung cancer diagnosis and prognosis. The purpose of this study was to determine the association between the promoter hypermethylation of multiple genes and 5-year survival rate in patients with Non-small cell lung cancer (NSCLC).
UNASSIGNED: Primary tumor samples (n = 65), corresponding nonmalignant lung tissues (n = 65), and circulating blood were obtained from NSCLC patients who underwent curative surgery. Promoter methylation status in seven genes (RASSF1A, CDH13, MGMT, ESR1, DAPK, SOX1, and HOXA9) was quantified by using bisulfite pyrosequencing. Five-year survival data were obtained by a clinician. Cox proportional hazards models were used to analyze the associations between gene methylation status and overall patient survival.
UNASSIGNED: The 5-year survival of the patients with SOX1 aberrant tumor methylation was found to be statistically significantly shorter than for those patients without aberrant tumor methylation (P = 0.01). This effect was independent of TNM stage. No significant survival differences were associated with aberrant methylation in other genes tested in either of the two tissue types.
UNASSIGNED: Our study shows that SOX1 promoter hypermethylation in NSCLC tumors is significantly associated with inferior survival, showing promise as a useful prognostic biomarker in patients with NSCLC.

BACKGROUND: The prognosis of gastric cancer in an advanced stage remains poor. The exact efficacy of the use of intraoperative sustained-release chemotherapy with 5-fluorouracil (5-FU) in advanced-stage gastric cancer is still unelucidated.
OBJECTIVE: To explore the long-term survival benefit of using sustained-release 5-FU implants in stage II and stage III gastric cancer patients.
METHODS: Patients with gastric cancer in a locally advanced stage and who underwent an R0 radical resection between Jan 2014, to Dec 2016, in this single institution were included. Patients with pathological diagnoses other than adenocarcinoma were excluded. All included patients were grouped according to whether intraoperative sustained-release (SR) chemotherapy with 5-FU was used or not (NSR). The primary end-point was 5-year overall survival. Kaplan-Meier method with log-rank test was used to analyze the overall survival of patients and Cox analysis was used to analyze prognosis factors of these patients.
RESULTS: In total, there were 563 patients with gastric cancer with locally advanced stage, who underwent an R0 radical resection. 309 patients were included in the final analysis. 219 (70.9%) were men, with an average age of 58.25 years. Furthermore, 56 (18.1%) received neoadjuvant chemotherapy, and 191 (61.8%) were in TNM stage III. In addition, 158 patients received intraoperative sustained-release chemotherapy with 5-FU and were included in the SR group, while the other 161 patients were included in the NSR group. The overall complication rate was 12.94% in the whole group and 10.81%, 16.46% in SR and NSR groups, respectively. There were no significant differences between the two groups in overall survival and complication rate (P > 0.05). The multivariate cox analysis indicated that only N Stage and neoadjuvant therapy were independent influencing factors of survival.
CONCLUSIONS: Intraoperative sustained-release chemotherapy usage with 5-FU, did not improve the survival of patients who underwent an R0 radical resection in locally advanced stage of gastric cancer.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a multisystem autoimmune disease with small-vessel involvement. In AAV, microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) are major clinicopathologic variants. In addition, myeloperoxidase (MPO) and proteinase 3 (PR3) are major target antigens. The objective of the study was to explore the predictive factors for long-term survival in AAV patients.
A multicenter retrospective study was carried out on 407 patients between 2005 and 2020. Clinical parameters were obtained from laboratory tests including the ANCA types, antinuclear antibody (ANA), extractable nuclear antigen (ENA), anti-streptolysin O (ASO), glomerular filtration rate (GFR), and the laboratory examinations for the blood routine, liver function, renal function, and immunity, etc. The data for clinical parameters were collected from electronic medical records (EMRs), and the data for patient survival were acquired through regular follow-up. The association of clinical parameters with overall survival (OS) along with 3-year and 5-year survival rates was analyzed, and the nomogram as a predictive model was established according to the analysis results.
In the present study, 336 (82.6%) patients and 46 (11.3%) patients were diagnosed with MPA and GPA, respectively. The mean and median OS for all the patients were 2,285 and 2,290 days, respectively. The 1-year, 3-year, 5-year, and 10-year cumulative survival rates for all the patients were 84.2%, 76.3%, 57.2%, and 32.4%, respectively. Univariate and multivariate survival analyses indicated that the independent prognostic factors included age, pathological categories (MPA, GPA, and other types), serum ANCA types (negative or positive for MPO and/or PR3), ANA, ASO, GFR, lymphocyte, neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein (CRP), and these clinical parameters except for ASO were used to construct a nomogram. The nomogram for 3-year and 5-year survival rates had a C-index of 0.721 (95% CI 0.676-0.766). The calibration curves showed that the predicted values of the nomogram for 3-year and 5-year survival rates were generally consistent with practical observed values, and decision curve analysis (DCA) further demonstrated the practicability and accuracy of the predictive model.
Laboratory tests at diagnosis have great significance in the prediction of long-term survival in AAV patients.
