Resumen Objetivos La mayoria de los ensayos clinicos realizados sobre pacientes con cancer escamoso anal (CEA) excluyen pacientes inmunodeprimidos. El objetivo del presente estudio es comparar las caracteristicas y los resultados oncologicos entre pacientes con CEA inmunocomprometidos e inmunocompetentes. Metodos Estudio multicentrico comparativo retrospectivo que incluye 2 cohortes consecutivas de pacientes, inmunocomprometidos e inmunocompetentes, diagnosticados de carcinoma escamoso anal. Se han investigado las caracteristicas de los pacientes, los tratamientos realizados, la respuesta clinica al tratamiento con quimiorradioterapia (QRT), la recidiva local o a distancia, la supervivencia global (SG) y la supervivencia libre de enfermedad (SLE). Resultados De enero 2012 a diciembre 2017 hemos estudiado a 84 pacientes, 47 (55,6%) mujeres, afectos de CEA, de los cuales 22 (26%) han sido pacientes inmunocomprometidos y 62 (74%) inmunocompetentes. Los pacientes inmunocomprometidos fueron mas jovenes (53 vs. 61 anos; p = 0,001), con un menor tamano tumoral (p = 0,044), y presentaban un mayor consumo de tabaco (p = 0,034) y de drogas de uso parenteral (p = 0,001). No se objetivaron diferencias significativas en los tratamientos administrados (p = 0,301), tampoco difirio la respuesta clinica a la QRT (83 vs. 100%). Tampoco se observaron diferencias significativas en la supervivencia global (60 vs. 64%; p = 0,756) o en la supervivencia libre de enfermedad a 5 anos (SLE) (65 vs. 68%; p = 0,338). Conclusiones En el presente estudio no se observaron diferencias significativas en relacion con los resultados oncologicos a largo plazo entre pacientes inmunocompetentes e inmunocomprometidos diagnosticados de CEA, con un grado de cumplimiento del tratamiento similar. Esta evidencia podria deberse al estrecho seguimiento y buen control terapeutico de pacientes infectados por HIV.

Background: Smoking participates in pathogenesis of lung cancer. Long non-coding RNAs (lncRNAs) play some specific roles during development of lung cancers. Objective: To investigate effects of smoking on lncRNA alterations in lung cancer. Methods: There are 522 lung adenocarcinoma (LUAD) and 504 lung squamous cell carcinoma (LUSC) participants. Clinical and lncRNA genetic data were downloaded from The Cancer Genome Atlas (TCGA) database. LncRNA alterations were analyzed in lung cancer patients. Smoking category and packs were evaluated. Correlations between smoking and LncRNA alterations were analyzed. Kaplan-Meier analysis was performed to determine overall survival and disease free survival. Results: There are more non-smokers in LUSC than in LUAD. In both LUAD and LUSC, smoking could increase total mutation counts and fraction of copy number alterations. Smoking index positively correlated with total mutations in LUAD, but not in LUSC. Smoking could trigger lncRNA alterations both in LUAD and LUSC. Smoking regulated different lncRNA between male and female. EXOC3-AS1 and LINC00603 alterations were positively correlated with smoking index in male LUAD smokers. In female LUAD smokers, smoking index was positively correlated with SNHG15, TP53TG1 and LINC01600 and negatively with LINC00609 and PTCSC3. In both male and female LUSC patients, smoking increased or decreased several lncRNA alterations. DGCR5 alteration increased in male LUSC than in female LUSC patients. In female LUSC patients, LOH12CR2 alteration was positively correlated with smoking index. Conclusions: Smoking promoted LUAD and LUSC development by affecting different lncRNA alterations in different genders.

Purpose. The objective of this study is to review randomized clinical trials systematically that compare the outcomes of preoperative and postoperative radiotherapy in the management of rectal cancer regarding locoregional recurrance, disease free survival and overall survival.Methods. The relevant randomized clinical trials are searched via online databases such as Pubmed, Ebsco, and Proquest. RCTs publised in English between 2000 until 2020 are selected and reviewed systematically.Result. Locoregional recurrence at 5 years was statistically lower in preoperative radiotherapy group than in postoperative radiotherapy group based on two studies. Disease free survival at 5-years was statistically higher in preoprative radiotherapy group than the postoperative one based on two studies. Overall survival at 5 years was not statistically significant between two groups for each study.Conclusion. Preoperative radiotherapy is superior to postoperative radiotherapy for controlling locoregional recurrence and disease free survival, but both are equal in overall survival.

We aimed to investigate prognostic values of preoperative neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) in resectable esophageal squamous cell carcinoma.Methods: A cohort of 167 resectable ESCC patients was retrospectively reviewed between January 2017 and September 2020. The best cut-off value of NLR and PLR was selected by plotting the receiver operating characteristic curve. All reviewed patients were divided into high NLR/PLR or low NLR/PLR group to evaluate prognostic factors.Results: Among the 167 patients, 34 (20.36%) were women and 133 (79.64%) were men. The mean age was 62.64 ± 7.91 years, with an age range from 44 to 85 years. All patients were divided into low NLR (< 2.20) or high NLR (≥ 2.20) group (AUC=62.5% with the sensitivity of 61.8% and specificity 60.9%, P=0.025), low PLR (< 110) or high PLR (≥ 110) group (AUC=59.6% with the sensitivity of 82.4% and specificity 35.3%, P=0.083). High NLR and PLR were associated with a larger tumor diameter (P< 0.05), while high NLR was also associated with poor tumor classification (P=0.022). There was a positive correlation between NLR and PLR (r = 0.614, P < 0.001). High NLR and PLR were significantly associated with poor disease-free survival. Multivariate analyses identified NLR as a prognostic factor in resectable ESCC.Conclusion: The NLR and PLR predict disease-free survival in resectable esophageal squamous cell carcinoma.Keywords: neutrophil lymphocyte ratio, platelet lymphocyte ratio, disease-free survival, resectable esophageal squamous cell carcinoma

Introduction Colorectal cancer (CRC) is the third most common cancer, accounting for approximately 10% of all cancer deaths. The incidence of CRC in young adults and the adolescent population is increasing. This study aims to highlight short-term outcomes for young patients with CRC. Methods Data were collected retrospectively for all patients aged less than 50 years diagnosed with CRC at a university teaching hospital between October 2012 and June 2018. The primary endpoints were disease-free survival (DFS) and overall survival (OS). Results A total of 120 patients (65 males, 55 females) with CRC aged under 50 years were initially included; 20 did not receive surgical treatment (12 metastatic adenocarcinoma, 5 metastatic squamous cell cancer (SCC), 3 neuroendocrine tumours (NET)), and 13 patients had insufficient data for analysis and were excluded. A total of 87 patients underwent surgical intervention and 66 with diagnosis of adenocarcinoma were included in survival analysis. Median age of patients was 42 years (19–49 years). Cancer recurrence was seen in 14 patients, 10 showing local, 3 liver and 1 lung metastasis. The median OS was 28 months (3–156 months). The median DFS was 13 months (3–85 months). Overall 5-year survival and DFS were 72% and 59%, respectively. Median survival in the group who did not undergo surgery was 4.5 months (1–15 months). Conclusions CRC is often more advanced and aggressive in younger patients. Current guidelines can result in young patients being investigated/treated for other gastrointestinal conditions before referral for CRC investigation.

In addition, 20 ages matched healthy females participated as a control group. Peripheral blood samples were collected from all participants in tubes containing heparin, fresh tumor tissues were also obtained from all patients undergoing surgery, and 20 normal breast tissue samples were obtained from the same patients’ areas adjacent to the safety margins; all these samples were taken for flow cytometric detection of Tregs.Results: The mean percentages of CD4+CD25+highT cells and Tregs were higher in TNBC peripheral blood than healthy controls and in malignant tissue than normal tissue. Moreover, the frequencies of tumor-infiltrating CD4+T cells and Tregs were exceeding those in the peripheral blood of cancer patients. Only tumor-infiltrating Tregs have shown increasing levels with the increase in the tumor size and were significantly higher in patients with local recurrences than those without recurrence. In addition, Tregs showed significant inverse relation with DFS and direct relation with the level of the peripheral Tregs.Conclusion: The findings of the current study support the possibility that TNBC microenvironment conveys specific characteristics on Tregs distinguishing them from those in normal breast tissue or Tregs in peripheral blood, improving the capabilities of tumor-infiltrating Tregs to enhance tumor growth, local recurrence and reduce the DFS.Keywords: triple negative breast cancer, Tregs, disease free survival, recurrences

Although immune checkpoint inhibitors (ICIs) have achieved unprecedented success in dMMR tumors, pMMR tumors accounting for 85% of colorectal cancer (CRC) cases remain unresponsive. Lactate dehydrogenase A (LDH‐A) is the rate‐limiting enzyme that catalyzes the transformation of pyruvate to lactate in the process of glycolysis. We investigated the relationship between LDH‐A and dMMR with the purpose of exploring the treatment strategy for pMMR CRC patients. We here show that LDH‐A can promote the proliferation of dMMR and pMMR CRC cells by positively regulating MMR proteins both in vitro and in vivo. LDH‐A inhibition can improve the efficacy of PD‐1 blockade in a pMMR CRC xenograft model. A statistical analysis of 186 CRC specimens showed a significant correlation between LDH‐A and dMMR status. Moreover, patients with both low LDH‐A expression and dMMR exhibited better disease‐free survival compared with patients with other combinations. The close correlation of LDH‐A and dMMR may offer a promising therapeutic strategy in which the combination of LDH‐A inhibitor and ICIs may improve the clinical benefit for pMMR CRC patients., Lactate dehydrogenase A (LDH‐A), stemness and vascular endothelial growth factor (VEGF) constitute a positive cycle, accounting for expression of MMR proteins and impaired immunity in a cooperative manner.

Background The expression of S100A8 and S100A9 is found to be related with the survival of cancer patients, but the results and information regarding their prognostic significance are inconsistent in literature. This study, therefore, aimed to perform a comprehensive meta-analysis and determine the prognostic significance of S100A8 and S100A9 expression in patients with cancer. Methods Data were collected by performing a literature search on the PubMed, Cochrane library, and Scopus databases. Pooled hazard ratio (HR) with confidence interval (CI) was calculated to assess the correlation between S100A8 and S100A9 expression and survival in patients with cancer. Results In total, 5 studies that enrolled 735 cancer patients were included in the meta-analysis. The pooled HR concerning S100A8 and S100A9 expression was 1.98 (95% CI: 1.20–3.29, P=0.008) for disease-free survival (DFS), indicating an association between high expression of S100A8 and S100A9 and poor DFS in cancer patients. However, the expression of S100A8 and S100A9 was not significantly correlated with disease-specific survival (HR 1.71, 95% CI: 0.86–3.40, P=0.128). Discussion The current meta-analysis revealed that S100A8 and S100A9 expression may be a potential prognosticator of DFS in cancer patients. The present systematic review is the first to investigate the survival outcomes of cancer patients with S100A8 and S100A9 expression.

Background Data on long-term cosmetic outcome, overall survival, and disease-free survival of endoscope-assisted partial mastectomy (EAPM) for breast cancer are scarce. Thus, we examined these outcomes after a 10-year follow-up period, and compared with conventional conservative method (CCM). Patients and methods Data on 257 patients with stage ≤ IIA breast cancer who underwent CCM (n = 125) or EAPM (n = 132) were analyzed. Cosmetic outcome at 2, 5, and 10 years was evaluated by 5 criteria (breast retraction assessment, nipple deviation, atrophy, skin change, scar). For overall mortality, breast cancer-specific mortality, and recurrence, the risk by operation method was tested by Cox proportional hazard models. Results EAPM performed significantly better than CCM in terms of cosmetic outcomes for location B at 2, 5, and 10 year-follow ups. As for cosmetic outcomes by individual criteria, EAPM had significantly higher proportions of satisfactory results for scar across all follow-up periods, and atrophy at 2-year and 10-year follow-up. There were no significant differences in terms of overall mortality, breast cancer-specific mortality, and recurrence between EAPM and CCM. The rates of patients who experienced local recurrence were similar between CCM and EAPM. Conclusion EAPM is better than CCM in terms of long-term cosmetic outcome, especially for location B. As a surgical treatment for breast cancer, EAPM is comparable to CCM in terms of mortality and recurrence.

Background Triple negative breast cancer (TNBC) which is treated with taxane, adriamycin and cyclophosphamide (TAC) chemotherapy regimen show variation in treatment response. CYP1B1 4326 C>G polymorphism has been implicated in contributing to the differences in treatment response in various types of cancers. Aim The objective of the present study was to investigate whether this polymorphism modulate the risk of disease recurrence in TNBC patients undergoing TAC chemotherapy regimen. Methods Blood samples of 76 immunohistochemistry confirmed TNBC patients were recruited. The genotyping of CYP1B1 4326 C>G polymorphism was carried out using PCR-RFLP technique. The genotype patterns were categorized into homozygous wildtype, heterozygous and homozygous variant. Kaplan-Meier analysis followed by Cox proportional hazard regression model were performed to evaluate the TNBC patients' recurrence risk. Results Out of 76 TNBC patients, 25 (33.0%) showed disease recurrence after one-year evaluation. Kaplan Meier analysis showed that TNBC patients who are carriers of CYP1B1 4326 GG variant genotypes (37.0%) had a significantly lower probability of disease-free rates as compared to TNBC patients who are carriers of CYP1B1 4326 CC/CG genotypes (71.0%). Univariate and multivariate Cox analysis demonstrated that TNBC patients who carried CYP1B1 4326 GG variant genotype had a significantly higher risk of recurrence with HR: 2.50 and HR: 4.18 respectively, even after adjustment as compared to TNBC patients who were carriers of CYP1B1 4326 CC and CG genotypes. Conclusion Our results demonstrate the potential use of CYP1B1 4325 GG variant genotype as a candidate biomarker in predicting risk of recurrence in TNBC patients undergoing TAC chemotherapy regimen.

In the present study, the potential of Raman spectroscopy (RS) in predicting disease-free survival (DFS) in oral cancer patients has been explored. Raman spectra were obtained from the tumor and contralateral regions of 94 oral squamous cell carcinoma patients. These patients were managed surgically and recommended for adjuvant therapy. The Cox proportional survival analysis was carried out to identify the spectral regions that can be correlated to DFS. The survival analysis was performed with 95% confidence intervals, hazard ratio, and p-values in the 1200-1800 cm-1 spectral region. Out of a total of 182 spectral points, 76 were found to be correlating with DFS, suggesting their utility to predict the patient outcome. The cut-off points of each correlating RS-point values were defined and tested towards predicting the DFS. The performance of predicting the power of spectral points was validated through Brier value, and it was found to be closer to the actual progression. The 76 spectral points identified from the tumors have the potential to accurately predict DFS in oral squamous cell carcinoma through a relatively simplistic prediction model in the absence of confounding factors.

Background: This retrospective research, it was aimed to evaluate disease-free survival (DFS) using inflammatory markers in esophageal cancer patients who received chemoradiotherapy (CRT). Methods: A total of 67 patients who received standard curative chemoradiotherapy for esophageal cancer were included in the study between 2011-2018. The patient, treatment characteristics, and pretreatment inflammatory markers were obtained from the patient's file. Results : Median follow up time was 18 months (6-72 months). ROC curve analyses showed the C-Reactive Protein-to-Albumin (CAR) cut-off value 0.9 for DFS (AUC:78.8%; sensitivity: 85%; specificity; 67.5%). 2-year disease free survival for CAR ≥0.9 and CAR P=0.035). The radiation doses >50Gy (versus 0.005).On the multivariate logistic analysis, our results showed that CAR < 0.9 [hazard ratio (HR) 1.29; 95% confidence interval [CI], 1.336-2.946; P = 0.014]; and radiation dose >50 Gy (HR 0.91; 95% CI, 1.229-4.997; P = 0.027) independent prognostic indictors. Conclusion: Our study found that the C-Reactive Protein/Albumin ratio is easy to apply and maybe a promising marker to predict disease-free survival in esophageal cancer patients who received chemoradiotherapy.

BACKGROUND Various surgical procedures have been described for gastrointestinal stromal tumors (GISTs) at the esophagogastric junction (EGJ) close to the Z-line. However, surgery for EGJ-GIST involving Z-line has been rarely reported. AIM To introduce a novel technique called conformal resection (CR) for open resection of EGJ-GIST involving Z-line. METHODS In this retrospective study, 43 patients having GISTs involving Z-line were included. The perioperative outcomes of patients receiving CR (n = 18) was compared with that of proximal gastrectomy (PG) (n = 25). RESULTS CR was successfully performed in all the patients with negative microscopic margins. The mean operative time, time to first passage of flatus, and postoperative hospital stay was significantly shorter in the CR group (P < 0.05), while the intraoperative blood loss was similar in the two groups. The postoperative gastroesophageal reflux as diagnosed by esophageal 24-h pH monitoring and quality of life at 3 mo were significantly in favor of CR compared to PG (both P < 0.001). The 5-year disease-free survival between the two groups was similar (P = 0.163). The cut- off value for the determination of CR or PG was 7.0 mm above the Z-line (83.33% sensitivity, 84.00% specificity, 83.72% accuracy). CONCLUSION CR is safe and feasible for EGJ-GIST located within 7.0 mm above the Z-line.

Introduction: The purpose of our study is to identify the association between body mass index (BMI) and absolute lymphocyte count (ALC), and to determine the effect of these two factors on the prognosis of breast cancer patients.Methods: We retrospectively identified 16,375 healthy female and 1,226 primary invasive breast cancer patients from Gangnam Severance Hospital. BMI and complete blood count (CBC) information at the time of diagnosed was collected. A multivariate Cox proportional hazard model was used to variable associated with disease-free survival (DFS).Results: BMI and ALC has positive correlation in breast cancer patients as well as health female (both P < .001). However, the effect of BMI and ALC on prognosis was the opposite. Overweight and obese had worse DFS (HR, 2.00; 95% CIs, 1.36-2.96; P < .001) than underweight or normal weight, but patients with high ALC had better DFS than those with low ALC (HR, 0.42; 95% CIs, 0.28-0.63; P < .001). When the risk stratification group was divided according to BMI /ALC, the high-risk group who had high BMI and low ALC had worse DFS than low-risk group (HR, 2.61; 95% CIs, 1.51-4.51; P = .001). In subgroup analysis, Her2-overexpressing and early stage tumor was more affected by BMI/ALC.Conclusions: The impact of BMI and ALC on prognosis in breast cancer was the opposite although BMI and ALC had positive correlation. Patients with high BMI and low ALC had worse DFS than others. Weight management is essential to breast cancer patients, and additional study about correlation between BMI and ALC affecting prognosis is needed in the future. Citation Format: Sung Min Ko.

Background: Breast cancer is the most common cancer worldwide. There has been emerging interest in studying differences in breast tumor phenotypes between South Asian and South American women given that racial/ethnic disparities in incidence and mortality have been demonstrated in multiple studies. South Asian women are more likely to be diagnosed with an advanced stage breast tumor despite lower incidence than in North American women. There is evidence that computer-extracted nuclear morphological features on H&E slide images may be associated with breast cancer aggressiveness, specifically recurrence and disease free survival. However, studies have mostly focused on North American women. In this work, we evaluated whether there is a difference in computer extracted features of nuclear morphology from H&E tissue slide images between South Asian (SA) and North American (NA) women and we also investigated how these differences could impact the development of population specific breast cancer prognostic models. Methods: H&E slides of breast tumors from patients who were diagnosed with ER+ early stage invasive breast cancer from Tata Memorial Centre, India (SA: 69 (20 recurrence)) and from University Hospitals Cleveland Medical Center (NA: 121 (20 recurrence)), along with outcome information were collected. All slides were digitized on either a Ventana DP 200 or a Roche Ventana iScan HT slide scanner. For each image, a conditional Generative Adversarial Network model was employed to segment the individual nuclei, which were used to generate 241 nuclear features including nuclear architecture, shape, orientation disorder, and texture features. Half of the patients (95) were randomly selected as the training set (Stra) with the remaining patients as the hold-out validation set (Stest). Three elastic net regularized Cox regression models (MSA, MNA, MSA+NA) were trained fitting between the nuclear features and disease free survival (DFS) respectively for SA subset, NA subset, and SA & NA set in Stra. The top five prognostic features were identified respectively from each of the three models (MSA, MNA, MSA+NA) which were further validated on Stest to evaluate their prognostic value in prediction of DFS. Results: We found that the prognostic features identified by MNA and MSA+NA were mostly shape features (three out of five for MNA, four out of five for MSA+NA), while the prognostic features identified by the model specifically trained with the SA population (MSA) were mostly texture features (three out of five), possibly reflecting chromatin patterns in the cell. MSA yielded a better performance (Hazard Ratio=4.99 (p=0.00928, CI=1.32-18.9) from log-rank test between model derived high and low risk categories) on SA population in Stest compared to MNA and MSA+NA. Conclusion: We found that nuclear histomorphometry features were different between breast cancer patients from South Asia and those from North America. The prognostic capability of the computational pathology-based models for South Asian women could be significantly improved by taking into account population-specific information. An additional independent validation set is needed to confirm the preliminary findings presented here.

Purpose: This study aims to analyse disease-free survival, overall survival and risk factors after orbital exenteration in patients with conjunctival and uveal melanoma. Methods: Patients who underwent orbital exenteration due to conjunctival and uveal melanoma were included in this retrospective study (March 2000 to March 2018). Results: A total of 76 patients were enrolled in this study: 60 patients had a conjunctival melanoma and 16 had a uveal melanoma. In conjunctival melanoma, the mean age was 68.4 years. The overall survival rate was 82% after 1 year and 52% after 5 years. Univariate analysis of overall survival found that the following parameters were predictive of a worse prognosis: gender, extent of the primary tumour, lymph node metastases, distant metastases, adjuvant chemotherapy or radiotherapy and relapse. In multivariate analysis, relapse and adjuvant radiotherapy appeared to contribute to a significantly worse prognosis. In uveal melanoma, the mean age was 63.6 years. Eleven patients died during follow-up (mean follow up 30.7 months). The overall survival and disease-free survival rates after 1 year were 62% and 57%, respectively. An analysis of risk factors was not possible due to the small number of cases. Conclusion: Orbital exenterations in conjunctival and uveal melanoma are rarely necessary, but can be performed as an ultima ratio treatment with curative intent. Disease-free survival and overall survival are significantly lower for both groups due to the advanced stage of the disease compared to patients treated without exenteration in the literature. If a recurrence occurs after exenteration, the prognosis is poor in both groups.

Purpose The identification of HER2 overexpression in a subset of gastric adenocarcinoma (GA) patients represents a significant step forward in unveiling the molecular complexity of this disease. The predictive and prognostic value of HER2 amplification in advanced HER2 inhibitor-treated GA patients has been investigated. However, its predictive value in resectable patients remains elusive. Methods We enrolled 98 treatment-naïve resectable Chinese GA patients with HER2 overexpression assessed using IHC. Capture-based targeted sequencing using a panel consisting of 41 gastrointestinal cancer-related genes was performed on tumor tissues. Furthermore, we also investigated the correlation between HER2 copy number (CN) and survival outcomes. Results Of the 98 HER2-overexpressed patients, 90 had HER2 CN amplification assessed using next-generation sequencing, achieving 92% concordance. The most commonly seen concurrent mutations were occurring in TP53, EGFR and PIK3CA. We found HER2 CN as a continuous variable was an independent predictor associated with DFS (p = 0.029). Our study revealed HER2 CN-high patients showed a trend of intestinal-type GA predominant (p = 0.075) and older age (p = 0.07). The median HER2 CN was 15.34, which was used to divide the cohort into CN-high and CN-low groups. Patients with high HER2 CN had a significantly shorter DFS than patients with low HER2 CN (p = 0.002). Furthermore, HER2 CN as a categorical variable was also an independent predictor associated with DFS in patients. Conclusion We elucidated the mutation spectrum of HER2-positive resectable Chinese GA patients and the association between HER2 CN and DFS. Our work revealed HER2 CN as an independent risk factor predicted unfavorable prognosis in HER2-positive GA patients and allowed us to further stratify HER2-positive resectable GA patients for disease management.

Objective: This study aimed to investigate the roles of MRPL27 in survival from cholangiocarcinoma patients in The Cancer Genome Atlas (TCGA) database. Methods: In TCGA-CHOL profile, MRPL27 gene expression and clinical data were obtained. Cox regression models were used to evaluate the potential links between MRPL27 and cholangiocarcinoma survival. Enrichment analysis of MRPL27 was conducted in Metascape and Gene Set Enrichment Analysis (GSEA) databases. Results: 36 cholangiocarcinoma patients were included in this analysis. MRPL27 mRNA was significantly upregulated in tumor tissues in cholangiocarcinoma patients including intrahepatic, distal and hilar/perihilar cholangiocarcinoma cases (all p < 0.01). Cholangiocarcinoma patients with high MRPL27 had worse overall survival (OS) and disease-free survival (DFS) compared to those with low MRPL27 (all p < 0.05). Univariate and multivariate Cox models indicated that MRPL27 should be a risk factor for the OS and DFS in cholangiocarcinoma patients (both p < 0.01). Bioinformatic analysis revealed that MRPL27 mainly involved in the processes of mitochondrial translation elongation, respiratory electron transport, ATP synthesis, and inner mitochondrial membrane organization. No mutations of MRPL27 were screened in cholangiocarcinoma patients. Conclusion: Upregulated in tumors, MRPL27 contributes to unfavorable survival in cholangiocarcinoma patients.

Objective: CA125 is a commonly used tumor marker in ovarian cancer patients for both diagnostic evaluation and follow-up period. In this study, we investigated the clinical importance of postoperative serum CA125 level normalization in ovarian cancer patients with high preoperative levels in terms of recurrence risk and disease free survival.Materials and Methods: We retrospectively analyzed operated ovarian cancer patients who were followed up in medical oncology clinic of Izmir Katip Celebi University Ataturk Training and Research Hospital between years 2005 – 2013. Two different analyses were done according to different CA125 cut-off levels; 35 IU/ml and 65 IU/ml.Results: There are 132 and 119 patients who had basal CA125 levels above normal (cut-off levels were >35 IU/ml and 65 IU/ml respectively). The number of patients who had normalized CA125 levels after surgery was 54 and 58, and who had still high levels was 78 and 61, respectively. For both CA125 cut-off values, there were statistically significant differences in disease free survival (32 month vs. 18 month p:0.015 - 32 month vs. 17 months p:0.001) and overall survival (108 month vs. 36 month p:0.015 - 89 month vs. 33 month p:0.000) between patients with normalized and not normalized postoperative CA125 levels.Conclusion: In operated ovarian cancer patients, who had high preoperative CA125 levels, the decrease in this value postoperatively must be evaluated and normalization of this tumor marker may give us an idea about the recurrence of the disease., Amaç: CA125, over kanseri hastalarında gerek tanı aşamasında gerekse tedavi sonrası takiplerde tümör belirteci olarak kullanılmaktadır. Biz de çalışmamızda preoperatif serum CA125 değeri yüksek olan over kanseri hastalarında operasyondan sonraki değerlerinin normale dönüp dönmemesinin nüks riskini belirleme ve nükse kadar geçen süre açısından önemini araştırdık. Yöntem: Çalışmamızda 2005 – 2013 yılları arasında İzmir Katip Çelebi Üniversitesi Atatürk Eğitim ve Araştırma Hastanesi Tıbbi Onkoloji Kliniğinde opere over kanseri tanısıyla takip ve tedavi edilen hastalar retrospektif olarak taranmıştır. CA125 sınır değeri olarak hem 35 IU/ml hem de 65 IU/ml kullanılarak iki farklı analiz yapılmıştır. Bulgular: Çalışmamıza bazal CA125 değeri yüksek olan (sınır değer >35 IU/ml ve 65 IU/ml alındığında) sırasıyla 132 ve 119 hasta alınmıştır. Preoperatif CA125 değeri yüksek olup postoperatif normale gelen hastaların sayısı sırasıyla 54 ve 58 iken bu değeri normalleşmeyen hastaların sayısı 78 ve 61’dir. Her iki CA125 sınır değeri için, postoperatif CA125 değeri normalleşenlerle normalleşmeyen hastalarda hem nükse kadar geçen süre (32 aya karşı 18 ay p:0,015 - 32 aya karşı 17 ay p:0,001) hem de tüm sağkalım açısından (108 aya karşı 36 ay p:0,015 - 89 aya karşı 33 ay p:0,000) istatistiksel anlamlı fark saptanmıştır.Sonuç: Opere over kanseri hastalarından bazal CA125 değeri yüksek saptanan hastalarda ameliyat sonrasındaki düşüşü değerlendirip, bu değerin normal sınırlara düşüp düşmemesine göre nüks süreci hakkında fikir sahibi olunabilinir.

Introduction Selected patients with colorectal cancer liver metastases (CRLM) and synchronous extrahepatic disease (EHD) are considered for surgery. Objectives To evaluate the change in surgical management and long-term survival (disease-free survival [DFS] and overall survival [OS]) for patients with CRLM and EHD who undergo positron emission tomography combined with computed tomography (PET-CT) vs no PET-CT. Methods Patients with CRLM were enrolled in a trial evaluating the effect of PET-CT (vs no PET-CT) on surgical management, DFS, and OS. This is a sub-study of the trial, including only patients with synchronous EHD. Cox proportional hazard models were used to calculate risks for recurrence and death. Survival were described by Kaplan-Meier method and compared with log-rank test. Results Of 25 patients with EHD (PET-CT arm: 14/270 (5%) and no PET-CT arm: 11/134 (8%)), PET-CT changed surgical management in 14%, all of which avoided liver resection due to more extensive disease. Complete metastasectomy was achieved in 36% (5/14) and 72% (8/11), respectively. Respectively, PET-CT vs no PET-CT had statistically similar median DFS, 5.6 months (95% confidence interval (CI) 3.6-18) vs 7.6 months (95% CI 2.9-15) and median OS, 42 months (95% CI 25-48) vs 29 months (95% CI 17-41). EHD was associated with worse DFS (hazard ratio HR = 1.89, 95% CI 1.41-2.52) and OS (HR = 2.47, 95% CI 1.6-3.83). Conclusions Preoperative PET-CT for the management of resectable CRLM did not improve long-term outcomes among patients who had synchronous EHD; however, it changed surgical management in a relatively significant proportion of patients.

Ramifications of postoperative complications on long-term survival after mastectomy are uncertain.Overall complications (Clavien-Dindo Grades I-IIIB) and wound complications were analyzed using the Kaplan-Meier method for impact on 5-year overall (OS) and disease-free survival (DFS).A total of 378 patients underwent mastectomy alone (157, 41%) or mastectomy with reconstruction (221, 59%) for Stage I-III disease with a median follow-up of 5 years. Postoperative complications occurred in 186 patients (49%), requiring non-surgical (I/II = 83, 22%) or surgical (IIIa/IIIb = 103, 27%) management. Wound complications occurred in 140 patients (37%). Reconstruction was associated with a higher rate of complication (P 0.001). Postoperative complications after mastectomy (with or without reconstruction) did not significantly affect OS or DFS. Wound complications also showed no significant effect on OS or DFS following mastectomy alone, or mastectomy with reconstruction.Postoperative complications after mastectomy, with or without reconstruction, bear no significant impact on 5-year survival.

BACKGROUND: There is limited data from Saudi Arabia on the demographic characteristics, outcomes and effectiveness of different treatment modalities in children with intracranial ependymoma. OBJECTIVE: Study the characteristics of pediatric ependymoma and outcomes of treatment modalities in Saudi Arabia. DESIGN: Retrospective. SETTING: Tertiary care center. PATIENTS AND METHODS: Children with intracranial ependymoma who were younger than 14 years of age and treated between 2006 and 2015 were included in the study. Patients with prior radiation, chemo-therapy, or surgical resection at other centers were excluded. MAIN OUTCOME MEASURES: Kaplan-Meier survival curves were used to estimate the event-free (EFS) and overall survival (OS) rates of the patients. SAMPLE SIZE: 22. RESULTS: Of the 22 children, 4 (18.2%) were less than three years old. All intracranial ependymomas had upfront surgical resection of the primary tumor. Gross total resection was achievable in 9 (42.9%) cases and subtotal resection in another 9 (42.9%). Near-total resection was done in 3 (14.3%) cases. Median time from surgery to start of radiotherapy was 62 days. RT was given to 17 (77.3%) patients. Both mean and median RT dose was 55.8 Gy. Only 5 (22.7%) of the children received chemotherapy. The median duration of follow-up was 5.38 years and the median time for EFS was 2.27 years. The cumulative OS rate of the study was 44.5%. The cumulative EFS survival rate of the study was 18.6%. Among demographic, pathological, radiological features, none had a statistically significant effect on the survival. CONCLUSIONS: The outcomes are comparable to those reported by international investigators for similar populations. Further improvements can be achieved by avoiding delays in radiation therapy and adding molecular staging. LIMITATIONS: The limited number of cases, retrospective nature, lack of molecular biology and size of the tumors. CONFLICT OF INTEREST: None.

Breast cancer is one of the most common malignant tumors in woman. Ovarian and pelvic metastasis in breast cancer are very rare, and the prognosis is often poor. Lacking typical clinical manifestation, misdiagnose is common. We report a case about a middle-aged postmenopausal woman with complaints of finding a left breast mass and irregular vaginal bleeding. Through ultrasound-guided core-needle biopsy of the masses, the patient’s final diagnosis was breast cancer with ovarian and pelvic metastasis. The patient received combinations of chemotherapy (intravenous infusion or peritoneal perfusion), radical surgery (gynecological operation and modified radical mastectomy), radiation and endocrine therapy. Forty-eight months follow-up showed that the patient is generally in good condition and had no signs of local recurrence or metastasis. Invasive ductal carcinoma (IDC) of the breast with unilateral ovarian and pelvic metastasis is rare. It is not easy to differentiate from primary ovarian malignant tumor, and the prognosis is generally poor. We chose a combination chemotherapy regimen sensitive to both breast and ovarian tumors for the patient. The therapeutic effect is remarkable. Only a small number of tumor cells were found in pelvic and ovarian tumors. The patient’s breast tumors reached pathological complete remission (pCR), which might be the reason for the patient’s good prognosis.

Contains fulltext : 229418.pdf (Publisher’s version ) (Open Access) BACKGROUND: Squamous cell carcinoma (SCC) of the external auditory canal (EAC) is a rare disease, which is commonly classified with the modified Pittsburgh classification. Our aim was to evaluate the predictive performance of this classification in relation to disease-free survival (DFS). METHODS: We examined retrospective data from a nationwide Dutch cohort study including patients with primary EAC SCC. These data were combined with individual patient data from the literature. Using the combined data, the predictive performances were calculated using the c-index. RESULTS: A total of 381 patients were included, 294 for clinical and 281 for the pathological classification analyses. The c-indices of the clinical and the pathological modified Pittsburgh classification predicting DFS were 0.725 (0.668-0.782) and 0.729 (0.672-0.786), respectively. CONCLUSION: The predictive performance of the modified Pittsburgh classification system as such appears to be acceptable to predict the DFS of EAC SCC. Other factors need to be added to a future model to improve the predicted performance.

BACKGROUND Colorectal cancer is a common digestive cancer worldwide. As a comprehensive treatment for locally advanced rectal cancer (LARC), neoadjuvant therapy (NT) has been increasingly used as the standard treatment for clinical stage II/III rectal cancer. However, few patients achieve a complete pathological response, and most patients require surgical resection and adjuvant therapy. Therefore, identifying risk factors and developing accurate models to predict the prognosis of LARC patients are of great clinical significance. AIM To establish effective prognostic nomograms and risk score prediction models to predict overall survival (OS) and disease-free survival (DFS) for LARC treated with NT. METHODS Nomograms and risk factor score prediction models were based on patients who received NT at the Cancer Hospital from 2015 to 2017. The least absolute shrinkage and selection operator regression model were utilized to screen for prognostic risk factors, which were validated by the Cox regression method. Assessment of the performance of the two prediction models was conducted using receiver operating characteristic curves, and that of the two nomograms was conducted by calculating the concordance index (C-index) and calibration curves. The results were validated in a cohort of 65 patients from 2015 to 2017. RESULTS Seven features were significantly associated with OS and were included in the OS prediction nomogram and prediction model: Vascular_tumors_bolt, cancer nodules, yN, body mass index, matchmouth distance from the edge, nerve aggression and postoperative carcinoembryonic antigen. The nomogram showed good predictive value for OS, with a C-index of 0.91 (95%CI: 0.85, 0.97) and good calibration. In the validation cohort, the C-index was 0.69 (95%CI: 0.53, 0.84). The risk factor prediction model showed good predictive value. The areas under the curve for 3- and 5-year survival were 0.811 and 0.782. The nomogram for predicting DFS included ypTNM and nerve aggression and showed good calibration and a C-index of 0.77 (95%CI: 0.69, 0.85). In the validation cohort, the C-index was 0.71 (95%CI: 0.61, 0.81). The prediction model for DFS also had good predictive value, with an AUC for 3-year survival of 0.784 and an AUC for 5-year survival of 0.754. CONCLUSION We established accurate nomograms and prediction models for predicting OS and DFS in patients with LARC after undergoing NT.

Prostate cancer (PC) is the most common non-cutaneous malignancy among men in the western world. However, heterogeneity remains a pressing clinical problem.The least absolute shrinkage and selection operator (LASSO) was used to screen the prognostic signature. Weighted correlation network analysis (WGCNA) was used to identify the target genes associated with high-risk characteristics. Gene set enrichment analysis was used to suggest the molecular mechanism ofTen DNA methylation sites were selected as the prognostic signature. A high expression ofWe developed a DNA methylation 10-CpG prognostic signature to predict the prognosis of PC patients. And the high expression of

PURPOSE Few studies have explored the relationship between body habitus and breast cancer outcomes in Caribbean women of African ancestry. This study evaluates the association between body mass index (BMI) and disease-free survival (DFS) in a retrospective cohort of 224 female Haitian patients with nonmetastatic breast cancer. PATIENTS AND METHODS BMI was obtained from the medical records and categorized as normal weight (< 25 kg/m2), overweight (25-29.9 kg/m2), and obese (≥ 30 kg/m2). DFS was defined as time from surgical resection to disease recurrence, death, or censoring. Kaplan-Meier survival curves were generated, and the association between BMI and DFS was evaluated using Cox proportional hazard models to control for multiple confounders. Exploratory analyses were conducted on weight changes during adjuvant chemotherapy. RESULTS Eighty-three patients (37.1%) were normal weight, 66 (29.5%) were overweight, and 75 (33.5%) were obese. There were no statistical differences in baseline characteristics or treatments received by BMI group. Twenty-six patients died and 73 had disease recurrence. Median DFS was 41.1 months. Kaplan-Meier estimates showed no significant DFS differences by BMI categories. After controlling for confounders, normal weight patients, when compared with overweight and obese patients, had adjusted hazard ratios of 0.85 (95% CI, 0.49 to 1.49) and 0.90 (95% CI, 0.52 to 1.55), respectively. Overall, mean weight loss of 2% of body weight was noted over the course of adjuvant chemotherapy. Patients who were postmenopausal ( P = .007) and obese ( P = .05) lost more weight than other groups. However, chemotherapy-related weight changes did not have an impact on DFS. CONCLUSION Baseline BMI and weight changes during adjuvant chemotherapy did not have an impact on DFS in this cohort. Future prospective studies in similar Caribbean breast cancer cohorts are needed to verify study findings.

Resumen Introduccion y objetivos Alrededor del 12% de los pacientes tratados con radioterapia pelvica desarrollan complicaciones en la vejiga. La terapia de oxigeno hiperbarico (TOHB) es una opcion para el manejo de la cistitis hemorragica inducida por radioterapia (CHIR). El objetivo de este estudio fue evaluar la eficacia de la TOHB para tratar la cistitis por radioterapia e identificar factores predictivos para un resultado exitoso. Material y metodos Revisamos retrospectivamente a 105 pacientes diagnosticados de CHIR que recibieron un tratamiento de TOHB entre 2007 y 2016 en nuestro centro. Los pacientes recibieron oxigeno al 100% en una camara hiperbarica multiplaza a 2,4 ATA durante 80 min. Todos los pacientes cumplimentaron un cuestionario en el que se documentaba la gravedad de los sintomas previos a la TOHB y tras el periodo de seguimiento. Resultados Despues de una media de 40 sesiones de TOHB, hubo una tasa de exito del 92,4% en el control de la hematuria. Durante el periodo de seguimiento (mediana de 63 meses), el 24,7% de los pacientes presentaron recurrencia de la hematuria. La puntuacion media de las variables evaluadas en el cuestionario —disuria, frecuencia urinaria y hematuria— fue significativamente menor despues del periodo de seguimiento (p Nuestros datos muestran que cuanto antes se administre la TOHB despues del primer episodio de hematuria, se logran mejores tasas de respuesta y se registran menores recurrencias en relacion con la hematuria (p Conclusiones Nuestros resultados apoyan la seguridad y los beneficios a largo plazo de la TOHB para la CHIR y otros sintomas molestos de la vejiga, lo que supondria una mejora en la calidad de vida de nuestros pacientes.

The relentless debate on postoperative adjuvant radiotherapy in gastric adenocarcinoma (GA) has been lasting for decades. In this study, a new biomarker, named promoter methylation burden of DNA repair genes (RPMB), was established to identify the subgroup of patients who might benefit from adjuvant radiotherapy. Methylation profiles of 397 GA tumor samples were downloaded from The Cancer Genome Atlas (TCGA). RPMB for a patient was defined as the ratio of methylated DNA repair genes to the number of all DNA repair genes. Subgroup analyses in term of overall survival (OS) and disease-free survival (DFS) indicated that most of the subgroups favored the high-RMPB group. Kaplan-Meier analysis showed that overall the patients with high RPMB after R0 resection had a significantly better clinical outcome regarding DFS (hazard ratio [HR] = 0.013, p = 0.042). Additionally, high-RPMB patients, who underwent adjuvant radiotherapy with both ≥T2 tumor and positive lymph nodes, showed superior DFS in comparison with the low-RPMB group (HR = 5.35 × 10−10, n = 26, p = 0.010). RPMB might be considered as a promising biomarker for decision-making with regard to postoperative adjuvant radiotherapy for GA patients., Graphical Abstract, To identify the subgroup of gastric adenocarcinoma (GA) patients who can benefit from postoperative adjuvant radiotherapy, An et al. proposed a new biomarker, named promotor methylation burden of DNA repair genes (RPMB), closely associated with patient prognosis, hopefully to provide guidance for treating GA patients after radical resection.

Background Aberrant activation of anaplastic lymphoma kinase (ALK) signaling has been found to be involved in the tumorigenesis of multiple types of cancer. The aim of this study was to determine the role of this pathway in the pathogenesis of breast cancer. Methods An ALK pathway signature that we generated previously was used to compute the ALK pathway activity in 6381 breast cancer samples from 42 microarray datasets, and the associations between ALK pathway signature score and clinical variables were examined using logistic regression and survival analyses. Results Our results indicated that high ALK pathway activity was a significant risk factor for hormone receptor‐negative, high‐grade breast cancer in the 42 datasets. ALK pathway activity was positively associated with pathological complete response (pCR) in 15 datasets annotated with patient's neoadjuvant chemotherapy response information (overall odds ratio = 1.67, P 50 years old, with positive lymph nodes, or with residual disease after neoadjuvant chemotherapy. Conclusions ALK may be involved in breast cancer tumorigenesis, and ALK pathway signature score may serve as a prognostic biomarker for breast cancer.

BACKGROUND AND OBJECTIVES Precise prognostic prediction for an individual hepatocellular carcinoma (HCC) patient before and after liver resection is important. We aimed to establish simple prognostic models to predict disease-free survival (DFS) for these patients. METHODS Six hundred and ninety-eight HCC patients with liver resections were reviewed. Preoperative (model 1) and postoperative (model 2) nomogram-based scoring systems were constructed by multivariate analyses, and DFS was estimated. RESULTS Among 698 patients, 490 (70.2%) patients had tumor recurrence at a median follow-up of 84.4 months. Risk factors of tumor recurrence in model 1 included viral hepatitis, platelet count, albumin, indocyanine green retention rate, multiplicity of tumor, and radiologic total tumor volume (TTV). Prognostic variables identified in model 2 were viral hepatitis, platelet count, multiplicity of tumor, cirrhosis, microvascular invasion, and pathologic TTV. By nomogram in model 1, the patients were classified into three groups with 5-year DFS of 61.0%, 35.7%, and 21.1%, respectively (P

Objective To compare drug (paclitaxel)-coated balloon angioplasty with femoropopliteal bypass surgery in the treatment of femoropopliteal lesions. Methods A retrospective study was performed between January 2015 and January 2019, covering a four-year period. All subjects who underwent femoropopliteal bypass surgery and drug-coated balloon angioplasty over a four-year period were evaluated. The subjects’ demographic characteristics, lesion characteristics, treatment outcomes and disease-free survival were collected. Subjects were divided into the femoropopliteal bypass group (Group A) and the drug-coated balloon angioplasty (Group B) group. Results In total, 220 subjects were enrolled. Both Group A and Group B consisted of 110 subjects. The proportion of patients with a claudication distance between 0 and 50 m was significantly higher in Group A, and the proportion of patients with a claudication distance between 50 and 100 m was significantly higher in Group B ( p = 0.001). In terms of the Rutherford levels, moderate claudication was significantly higher in Group B, and severe claudication was significantly higher in Group A ( p = 0.001). The lesion length for the subjects in Group A was significantly longer than that in Group B (24.61 ± 2.79 mm for Group A and 18.59 ± 3.95 mm for Group B, p = 0.001). The stenosis degree in Group A was also significantly higher than that in Group B (96.82 ± 4.32% for Group A and 94.85 ± 4.55% for Group B, p = 0.001). The duration of the procedure, duration of hospitalization and rate of bleeding in Group A were significantly higher than those in Group B. The incidence of overall morbidity and reintervention rates in Group B were significantly higher than that in Group A. The preoperative ankle brachial index values of the subjects in Group B were statistically significantly higher than those in Group A (0.56 ± 0.08 for Group A and 0.61 ± 0.08 for Group B, p = 0.001). The change in the ankle brachial index measurement of the subjects in Group A with respect to the preprocedure value was significantly greater than that in Group B ( p = 0.001). For primary patency, there was a significant difference between the groups in the distribution of the duplex ultrasound results at the 3rd, 6th, 9th and 12th month control points ( p = 0.001). At all control points, Group A had better primary patency rates, whereas the secondary patency rates did not differ. In total, among the 220 patients, 125 (56.8%) were disease free, and 95 (43.2%) experienced recurrence. The mean disease-free survival times for Group A and Group B were 10.45 ± 0.28 months and 9.11 ± 0.37 months, respectively. The disease-free survival rates were significantly higher in Group A ( p = 0.001, p Conclusion Femoropopliteal bypass resulted in better disease-free survival rates than drug-coated balloon angioplasty and serves as an effective modality for the treatment of femoropopliteal lesions.
