Introduction: The objectives of this investigation are to characterize the epidemiology of base of tongue adenocarcinoma utilizing a population-based database and to identify prognostic factors that may affect survival. Methods: A retrospective cohort study was conducted using the Surveillance, Epidemiology, and End Results database. Univariate Kaplan-Meier analysis and multivariate Cox-regression analysis were performed to evaluate the association of suspected prognostic factors with survival. Overall survival (OS) and disease-specific survival (DSS) were the primary outcome measures. Results: A total of 176 cases were eligible based on inclusion criteria. The 5-year OS and DSS were 49% and 66%, respectively. On multivariate analysis, surgical management was associated with improved OS and DSS (OS hazard ratio [HR]: 0.34, 95% confidence interval [CI]: 0.20-0.58, P < .001; DSS HR: 0.20, 95% CI: 0.09-0.48, P < .001), while higher tumor grade was associated with worse OS and DSS (OS HR: 1.58, 95% CI: 1.14-2.19, P = .006; DSS HR: 1.68, 95% CI: 1.01-2.79, P = .045). Administration of chemotherapy or radiation did not have a significant association with OS or DSS. Conclusion: This investigation is the largest to date to analyze the base of tongue adenocarcinoma as its own entity. Surgery remains the mainstay of treatment, and lower tumor grade is associated with improved survival in these patients. Administration of radiation or chemotherapy was not associated with improved survival.

Aim We aim to investigate the clinical characteristics of the rectal NECs and the prognosis-related factors and construct a nomogram for prognosis prediction. Methods The data of 41 patients and 1028 patients with rectal NEC were retrieved respectively from our institution and SEER database. OS or PFS was defined as the major study outcome. Variables were compared by chi-square test and t-test when appropriate. Kaplan–Meier analysis with log-rank test was used for survival analysis and the Cox regression analysis was applied. The nomogram integrating risk factors for predicting OS was constructed by R to achieve superior discriminatory ability. Predictive utility of the nomogram was determined by concordance index (C-index) and calibration curve. Results In the univariate and multivariate analyses, tumor differentiation, N stage, M stage and resection of primary site were identified as independent prognostic indicators. The linear regression relationship was found between the value of Ki-67 index and the duration of OS (P < 0.05). Furthermore, the independent prognostic factors were added to formulate prognostic nomogram. The constructed nomogram showed good performance according to the C-index. Conclusions Contrary to WHO classification guideline, we found that the rectal NEC diseases are heterogeneous and should be divided as different categories according to the pathological differentiation. Besides, the nomogram formulated in this study showed excellent discriminative capability to predict OS for those patients. More advanced predictive model for this disease is required to assist risk stratification via the formulated nomogram.

Abstract Background The recurrence after curative surgery of the rectal adenocarcinoma is a serious complication, considered as a failure of the therapeutic strategy. The aim of this study was to identify the different prognostic factors affecting the recurrence of adenocarcinoma of the rectum. Methods A retrospective analysis of patients operated for adenocarcinoma of the rectum between January 2000 and December 2015 was conducted. The study of the recurrence rate and prognostic factors was performed through the Kaplan Meier survival curve and the Cox regression analysis. Results During the study period, 188 patients underwent curative surgery for rectal adenocarcinoma, among which 53 had a recurrence. The recurrence rate was 44.6% at 5 years. The multivariate analysis identified four parameters independently associated with the risk of recurrence after curative surgery: a distal margin ≤ 2 cm (HR = 6.8, 95% CI 2.7–16.6, 6), extracapsular invasion of lymph node metastasis (HR = 4.4, 95% CI 1.3–14), tumor stenosis (HR = 4.3, 95% CI 1.2–15.2), and parietal invasion (pT3/T4 disease) (HR = 3, 95% CI 1.1–9.4). Conclusion The determination of the prognostic factors affecting the recurrence of rectal adenocarcinoma after curative surgery allows us to define the high-risk patients for recurrence.

Abstract Background Angiosarcomas (AS) have poor prognosis and often metastasize to distant sites. The potential predictors of metastatic angiosarcomas (MAS) have not been extensively investigated. The main objective of this study was to identify survival predictors of MAS. Methods Surveillance, Epidemiology, and End Results (SEER) datasets were used to identify patients with MAS from 2010 to 2016. Risk predictors were determined with the aid of Kaplan-Meier and Cox regression model analyses. Results A total of 284 MAS patients met the study entry criteria. Among these, 121 patients (42.6%) were diagnosed with metastasis in bone, 26 in brain (9.2%), 86 in liver (30.3%) and 171 in lung (60.2%). Overall, 96 patients (33.8%) had two or more metastatic sites. The 1- and 3-year overall survival (OS) rates were 20.8 and 3.8% while 1- and 3-year cancer-specific survival (CSS) rates were 22.0 and 5.2%, respectively. Cox regression analysis revealed chemotherapy, radiation treatment (RT) and tumor size ≤10 cm as independent favorable predictors of OS. In terms of CSS, tumor grade IV, tumor size > 10 cm and absence of chemotherapy were independent adverse predictors. Surgery did not prolong survival outcomes (both OS and CSS) in the current cohort. Conclusion MAS is associated with extremely poor survival. Chemotherapy, RT, and tumor size are independent predictors of OS. Chemotherapy and tumor size are independent prognostic factors of CSS. Chemotherapy is therefore recommended as the preferred treatment option for MAS patients.

Object The goal of this paper was to investigate the long-term outcome and the possible prognostic factors that might have influenced the persistence of posttraumatic epilepsy after penetrating head injuries sustained during the Iraq–Iran war (1980–1988). Methods In this retrospective study, the authors evaluated 189 patients who sustained penetrating head injury and suffered posttraumatic epilepsy during the Iraq–Iran war (mean 18.6 ± 4.7 years after injury). The probabilities of persistent seizures (seizure occurrence in the past 2 years) in different periods after injury were estimated using the Kaplan-Meier method. The possible prognostic factors (patients and injury characteristics, clinical findings, and seizure characteristics) were studied using log-rank and Cox regression analysis. Results The probability of persistent seizures was 86.4% after 16 years and 74.7% after 21 years. In patients with < 3 pieces of shrapnel or no sphincter disturbances during seizure attacks, the probability of being seizure free after these 16 and 21 years was significantly higher. Conclusions Early seizures, prophylactic antiepileptics drugs, and surgical intervention did not significantly affect long-term outcome in regard to persistence of seizures.

Abstract Background To elucidate the bladder rhabdomyosarcoma clinicopathological characteristics and reveal the prognostic factors. Methods We screened data from SEER database (1975-2016) stratified by age group, evaluated the differences between groups with Chi-square and Fisher’s test, conducted the Kaplan-Meier survival analysis and plotted the survival curve. The significant factors were brought into Cox regression analysis and calculated the HR(95%CI). Results About half of the patients who develop bladder RMS will be younger than 2 years of age. Embryonal RMS account for 76% of all histopathology types. Age at diagnosis more than 16-y (HR=6.595,95%CI:3.62-12.01, p=7.04e-10), NOT embryonal rhabdomyosarcoma (HR=3.61, 95%CI:1.99-6.549, p =4.1e-06), without radiotherapy combined or surgery alone (HR=4.382, 95%CI:1.99-6.549, p =2.4e-05) and not performed the surgery (HR=2.982,95%CI:1.263-7.039, p =0.0126) were negatively correlated with 5-year survival time, while race( p =0.341), whether performed the lymphadenectomy( p =0.722) showed no influence on survival time. Cox regression results show that age, histology, SEER stage, treatment combined or alone influence the clinical outcomes. Conclusions We demonstrated the demographic and characteristic of bladder rhabdomyosarcoma, identified and excluded the prognostic factors for the 5-year overall survival and clinical outcomes.

Background The United Kingdom has lower survival figures for all types of cancers compared to many European countries despite similar national expenditures on health. This discrepancy may be linked to long diagnostic and treatment delays. Objective The aim of this study was to determine whether delays experienced by patients with colorectal cancer (CRC) affect their survival. Methods This observational study utilized the Somerset Cancer Register to identify patients with CRC who were diagnosed on the basis of positive histology findings. The effects of diagnostic and treatment delays and their subdivisions on outcomes were investigated using Cox proportional hazards regression. Kaplan-Meier plots were used to illustrate group differences. Results A total of 648 patients (375 males, 57.9% males) were included in this study. We found that neither diagnostic delay nor treatment delay had an effect on the overall survival in patients with CRC (χ23=1.5, P=.68; χ23=0.6, P=.90, respectively). Similarly, treatment delays did not affect the outcomes in patients with CRC (χ23=5.5, P=.14). The initial Cox regression analysis showed that patients with CRC who had short diagnostic delays were less likely to die than those experiencing long delays (hazard ratio 0.165, 95% CI 0.044-0.616; P=.007). However, this result was nonsignificant following sensitivity analysis. Conclusions Diagnostic and treatment delays had no effect on the survival of this cohort of patients with CRC. The utility of the 2-week wait referral system is therefore questioned. Timely screening with subsequent early referral and access to diagnostics may have a more beneficial effect.

Abstract INTRODUCTION NM occurs in 5 - 15% of cancer patients and Overall Survival (OS) in treated patients ranges from 2-6 months. The purpose of this study was to analyze the effect of prognostic factors on OS and calculate a graded prognostic assessment (GPA) score based on tissue type, similar to the index score created for cancer patients with brain metastases (BM). METHODS We conducted a single center, retrospective analysis of 118 patients diagnosed between 2006 and 2018 at TMC. The prognostic factors analyzed were: Age (&lt; = 50yo =1pt), Karnofsky Performance Status (KPS &gt; =60 =1 pt), and no extracranial metastases (1pt). The GPA score was calculated from 0.0 - 3.0 by adding the points together. Kaplan Meier curves were used to estimate OS for primary tumors with 10 or more patients (breast, lung, leukemia, lymphoma). Cox regression analysis was used to evaluate the association of the GPA with OS. RESULTS The GPA analysis by tumor type included 76% of the patient population. The median OS was 5 months (breast), 2 months (lung), 7 months (leukemia), and 2 months (lymphoma). We found that leukemia (p =0.008, N = 20) and lung cancer (p =0.002, N = 20) patients showed distinct separation between GPA groups on their Kaplan Meier curves. Higher KPS was associated with increased OS (p &lt; 0.0001) using Cox regression. DISCUSSION: The GPA algorithm was only partially successful in our NM population, which may reflect the smaller number of patients in our study compared to the studies used to create the BM GPA. TMC is a contributing institution to a large, multi-institutional, multi-national registry of patients with NM disease (Neoplastic Meningitis Registry - NeMeRe). We plan to use this larger dataset to validate our GPA score as a useful tool for predicting OS in NM patients.

Background: The objective of the present study was to evaluate the role of the TGFβ/PDCD4/AP-1 pathway in nasopharyngeal carcinoma (NPC) and its relationship to NPC prognosis. Methods: NPC tissues collected from 66 NPC patients were compared to 17 nasopharyngeal mucosa biopsy specimens collected as normal tissues. Immunohistochemical staining was performed to assess expression of transforming growth factor-β receptor I (TGFβRI), programmed cell death 4 (PDCD4) and activator protein-1 (AP-1). The Kaplan-Meier method was applied to evaluate NPC patient overall survival (OS) and progression-free-survival (PFS). Cox regression analysis was used to estimate independent prognostic factors for NPC. The human NPC cell line CNE2 was selected and treated with SB431542, an inhibitor of TGFβRI; expression of TGFβRI and PDCD4 in CNE2 cells was determined by western blotting. NPC tissues showed higher expression of TGFβRI and AP-1 but lower expression of PDCD4 than normal tissues (all P < 0.05). Results: The results of Kaplan-Meier analysis showed that TGFβRI-positive patients and AP-1-positive patients had shorter OS and PFS than TGFβRI-negative patients and AP-1-negative patients; additionally, PDCD4-positive patients had higher OS and PFS than PDCD4-negative patients. Cox regression analysis revealed that advanced tumor stage, overexpression of TGFβRI and AP-1, and low expression of PDCD4 were unfavorable factors influencing OS and PFS in NPC patients. Compared with the control group, expression of TGFβRI decreased and that of PDCD4 increased significantly in CNE2 cells treated with the inhibitor (all P < 0.05). These findings indicate that the TGFβ/PDCD4/AP-1 pathway may be associated with NPC development and progression. Conclusion: High expression of TGFβRI and AP-1 and low expression of PDCD4 may be unfavorable prognostic factors for NPC.

Introduction: Ewing Family Tumour (EFT) is a group of rare malignant and aggressive tumour, with a considerably improved prognosis. However, there is lack of study on the outcome of children with EFT in Malaysia. Objectives: The study aimed to evaluate the Overall Survival (OS) rate, Event Free Survival (EFS) rate and identify the prognostic factors that determined the EFT outcome at Hospital Universiti Sains Malaysia (USM). Methodology: A retrospective record review of children aged 0-18 years with EFT was done. Patients were identified from the registration data in the Oncology Unit and Record Office of Hospital USM. For patients with untraceable information or deceased, a letter was sent to State Registry to obtain the outcome of the patient. The association between demographics and patients’ clinical factors was determined using the Cox regression. Survival curves were estimated by the Kaplan-Meier method and were compared using the Log-rank test. Results: There were 51 patients identified but 29 of them were eligible for the study. The mean duration of follow-up was 21 months. The OS rate at 1, 2, 3 and 5 years were 62.1%, 44.8%, 30.2% and 21.6% respectively. The EFS rate at 1, 2, 3 and 5 years were 41.9%, 26.7%, 17.8% and 0% respectively. Multivariate Cox regression analysis showed that the presence of surgical intervention (p = 0.030) and major complications (p = 0.045) were the significant prognostic factors to the survival of EFT. Conclusion: The survival rate of EFT among our patients was comparable to other developing countries, with surgical intervention and the presence of major complications as independent prognostic factors.
