Quantitative analysis of computed tomography (CT) radiomic features is an indirect measure of tumor heterogeneity, which has been associated with prognosis in human lung carcinoma. Canine lung tumors share similar features to human lung tumors and serve as a model in which to investigate the utility of radiomic features in differentiating tumor type and prognostication. The purpose of this study was to correlate first-order radiomic features from canine pulmonary tumors to histopathologic characteristics and outcome. Disease-free survival, overall survival time and tumor-specific survival were calculated as days from the date of CT scan. Sixty-seven tumors from 65 dogs were evaluated. Fifty-six tumors were classified as primary pulmonary adenocarcinomas and 11 were non-adenocarcinomas. All dogs were treated with surgical resection; 14 dogs received adjuvant chemotherapy. Second opinion histopathology in 63 tumors confirmed the histologic diagnosis in all dogs and further characterized 53 adenocarcinomas. The median overall survival time was longer (p = 0.004) for adenocarcinomas (339d) compared to non-adenocarcinomas (55d). There was wide variation in first-order radiomic statistics across tumors. Mean Hounsfield units (HU) ratio (p = 0.042) and median mean HU ratio (p = 0.042) were higher in adenocarcinomas than in non-adenocarcinomas. For dogs with adenocarcinoma, completeness of excision was associated with overall survival (p<0.001) while higher mitotic index (p = 0.007) and histologic score (p = 0.037) were associated with shorter disease-free survival. CT-derived tumor variables prognostic for outcome included volume, maximum axial diameter, and four radiomic features: integral total, integral total mean ratio, total HU, and max mean HU ratio. Tumor volume was also significantly associated with tumor invasion (p = 0.044). Further study of radiomic features in canine lung tumors is warranted as a method to non-invasively interrogate CT images for potential predictive and prognostic utility.

Head and neck squamous cell carcinoma (HNSCC) rank seventh among the most common type of malignant tumor worldwide. Various evidences suggest that transcriptional factors (TFs) play a critical role in modulating cancer progression. However, the prognostic value of TFs in HNSCC remains unclear. Here, we identified a risk model based on a 12-TF signature to predict recurrence-free survival (RFS) in patients with HNSCC. We further analyzed the ability of the 12-TF to predict the disease-free survival time and overall survival time in HNSCC, and found that only NR5A2 down-regulation was strongly associated with shortened overall survival and disease-free survival time in HNSCC. Moreover, we systemically studied the role of NR5A2 in HNSCC and found that NR5A2 regulated HNSCC cell growth in a TP53 status-dependent manner. In p53 proficient cells, NR5A2 knockdown increased the expression of TP53 and activated the p53 pathway to enhance cancer cells proliferation. In contrast, NR5A2 silencing suppressed the growth of HNSCC cells with p53 loss/deletion by inhibiting the glycolysis process. Therefore, our results suggested that NR5A2 may serve as a promising therapeutic target in HNSCC harboring loss-of-function TP53 mutations.

Introduction: In this study, we evaluated the use and the contribution of radiopharmaceuticals to the field of lung neoplasms imaging using positron emission tomography/computed tomography. Methods: We conducted review of the current literature at PubMed/MEDLINE until February 2020. The search language was English. Results: The most widely used radiopharmaceuticals are the following: Experimental/pre-clinical approaches: (18)F-Misonidazole (18F-MISO) under clinical development, D(18)F-Fluoro-Methyl-Tyrosine (18F-FMT), 18F-FAMT (L-[3-18F] (18)F-Fluorothymidine (18F-FLT)), (18)F-Fluoro-Azomycin-Arabinoside (18F-FAZA), (68)Ga-Neomannosylated-Human-Serum-Albumin (68Ga-MSA) (23), (68)Ga-Tetraazacyclododecane (68Ga-DOTA) (as theranostic agent), (11)C-Methionine (11C-MET), 18F-FPDOPA, ανβ3 integrin, 68Ga-RGD2, 64Cu-DOTA-RGD, 18F-Alfatide, Folate Radio tracers, and immuno-positron emission tomography radiopharmaceutical agents. Clinically approved procedures/radiopharmaceuticals agents: (18)F-Fluoro-Deoxy-Glucose (18F-FDG), (18)F-sodium fluoride (18F-NaF) (bone metastases), and (68)Ga-Tetraazacyclododecane (68Ga-DOTA). The quantitative determination and the change in radiopharmaceutical uptake parameters such as standard uptake value, metabolic tumor volume, total lesion glycolysis, FAZA tumor to muscle ratio, standard uptake value tumor to liver ratio, standard uptake value tumor to spleen ratio, standard uptake value maximum ratio, and the degree of hypoxia have prognostic and predictive (concerning the therapeutic outcome) value. They have been associated with the assessment of overall survival and disease free survival. With the positron emission tomography/computed tomography radiopharmaceuticals, the sensitivity and the specificity of the method have increased. Conclusion: In terms of lung cancer, positron emission tomography/computed tomography may have clinical application and utility (a) in personalizing treatment, (b) as a biomarker for the estimation of overall survival, disease free survival, and (c) apply a cost-effective patient approach because it reveals focuses of the disease, which are not found with the other imaging methods.

Abstract Abstract 4302 Introductions Allogenic stem cell transplantaion (allo-SCT) for non-Hodgkin's lymphomas (NHLs) may be curative for chemorefractory patients, but few studies are available to guide transplant decision making in this setting. It would be very important to assess the eligibilities of allo-SCT for NHLs. To clarify the possibilities and eligibilities of allo-SCT for aggressive NHLs and come out the better prognostic factors, we analyzed 18 NHL patients who underwent allo-SCT in our institute retrospectively. Design and methods There were 55 NHL patients who had been undergone allo-SCT in our institute from August 2001 to March 2009. Thirty-seven patients out of 55 were adult T-cell leukemia/lymphoma (ATLL) patients, and we excluded these 37 ATLL patients in this study so that eliminate selection bias. We analyzed about rest of 18 patents. We analyzed 3 years overall survival (OS), disease free survival (DFS), related factors such as gender, age, diagnosis, disease status, IPI, HCT-CI score, transplantation methods, acute GVHD, chronic GVHD, and causes of death. Results Median age was 37.5 years old (19-63). Thirteen patients were male and 5 female. Diagnosis included FL (n=4), PTCL-u (n=3), MNKL (n=3), BL (n=2), DLBCL (n=2), ALCL (n=1), T-LBL (n=1), hepatosplenic lymphoma (n=1), and MF (n=1). Median overall survival time and disease free survival time after SCT were 215.5 days (6-2436) and 73 days (2-2436). Overall survival rate after SCT was 38.9%. IPI was Low in 2 patients, 8 L-I, 5 H-I, and 3 High. Low/L-I group showed significantly superior OS, DFS compare to H-I/High group (54% vs 0% p=0.0014, 56.3% vs 0% p=0.0112). HCT-CI scoring 0 in 12 patients, five 1, and only one patient scored over 2. HCT-CI score significantly related to OS after SCT in our cases (p=0.024). There were 13 sibling donors (included 5 HLA haplo-identical donors) and 5 unrelated donors (URD) (included 2 cord blood donors) in our cases. Ten patients received myeloablative conditioning and 8 reduced intensity conditioning (RIC). Disease status at SCT was CR in 5 patients, 7 PR, and 6 PD. Eleven patients died after SCT (3 a-GVHD, 2 disease progression, 2 sepsis, 1 TMA, 1 pneumonia, 1 invasive aspergillosis, and 1 liver failure). Five patients died within 100 days after SCT (three patients died within day 30). Six patients have been alive over 3 years (3 yrs OS, DFS: 33.3%, 27.8%). Seven patients were complicated grade 0-1 a-GVHD and 9 grade 2-4. Grade 0-1 group patients showed significantly superior DFS compare to grade 2-4 (p=0.0314). Five patients complained limited c-GVHD and 3 extensive. The patients group complained with c-GVHD showed better OS and DFS than asymptomatic group (53.6% vs 12.0% p=0.0062, 58.3% vs 12.5% p=0.0267). Four patients suffered relapse or progressive disease after SCT. Two out of these 4 patients showed GVL effect only with reducing immunosuppressive therapies. Discussion and conclusion Interestingly, about a-GVHD, grade 2-4 group obtained poor prognostic result compared to grade 0-1 group. On the other hand, the group which showed c-GVHD obtained better survival results. Our study was based on relatively small numbers of cases, but it might be showed that c-GVHD is important and GVL effect would be possibly existed. 3 years OS and DFS of allo-SCT for chemorefractory NHL in our institute were 33.3%, 27.8%, and NRM was 50%. Although it was not acceptable results, in some groups such as IPI Low/L-I, low scored HCT-CI groups, allo-SCT would be acceptable. Further studies including large patients numbers will be required. Disclosures: No relevant conflicts of interest to declare.

Background: Uveal melanoma is the most common primary intraocular malignancy in adults. In advanced cases, the prognosis is very poor. Thus far, no effective methods of pharmacotherapy of this cancer have been found. The aim of the study was to evaluate the expression of PARP-1, the best-known member of the family of poly(ADP-ribose) polymerases, in uveal melanoma and its associations with clinicopathological parameters, overall survival, and disease-free survival. Methods: The study included 91 patients who underwent enucleation due to uveal melanoma. PARP-1 expression was assessed by immunohistochemistry. Results: High PARP-1 expression was associated with more frequent chromosome 3 loss, higher histopathological grade, bigger tumor size, and absence of intrascleral extension. High PARP-1 expression was associated with shorter overall survival time and disease-free survival time. Conclusions: The above findings indicate that high expression of PARP-1 can be considered as an unfavorable prognostic factor in uveal melanoma.

Abstract Objective There are limited data from retrospective studies on whether therapeutic outcomes after regular pancreatectomy are superior to those after enucleation in patients with small, peripheral and well-differentiated non-functional pancreatic neuroendocrine tumors. This study aimed to compare the short- and long-term outcomes of regular pancreatectomy and enucleation in patients with non-functional pancreatic neuroendocrine tumors. Methods Between January 2007 and July 2020, 227 patients with non-functional pancreatic neuroendocrine tumors who underwent either enucleation (n = 89) or regular pancreatectomy (n = 138) were included. Perioperative complications, disease-free survival, and overall survival probabilities were compared. Propensity score matching was performed to balance the baseline differences between the two groups. Results The median follow-up period was 60.76 months in the enucleation group and 43.29 months in the regular pancreatectomy group. In total, 34 paired patients were identified after propensity score matching. The average operative duration in the enucleation group was significantly shorter than that in the regular pancreatectomy group (147.94 ± 42.39 min versus 217.94 ± 74.60 min, P &lt; 0.001), and the estimated blood loss was also significantly lesser (P &lt; 0.001). The matched patients who underwent enucleation displayed a similar overall incidence of postoperative complications (P = 0.765), and a comparable length of hospital stay (11.12 ± 3.90 days versus 9.94 ± 2.62 days, P = 0.084) compared with those who underwent regular pancreatectomy. There were no statistically significant differences between the two groups in disease-free survival and overall survival after propensity score matching. Conclusion Enucleation in patients with non-functional pancreatic neuroendocrine tumors was associated with shorter operative time, lesser intraoperative bleeding, similar overall morbidity of postoperative complications, and comparable 5-year disease-free survival and overall survival when compared with regular pancreatectomy.

Background: Genetic variations in oxidative stress-related genes may alter the coded protein level and impact the pathogenesis of breast cancer. Methods: The current study investigated the associations of functional single nucleotide polymorphisms in the NFE2L2, HMOX1, P21, TXNRD2, and ATF3 genes with the early-stage breast cancer clinicopathological characteristics and disease-free survival, metastasis-free survival, and overall survival. A total of 202 Eastern European (Lithuanian) women with primary I–II stage breast cancer were involved. Genotyping of the single nucleotide polymorphisms was performed using TaqMan single nucleotide polymorphisms genotyping assays. Results: The CA+AA genotypes of P21 rs1801270 were significantly less frequent in patients with lymph node metastasis and larger tumor size ( P=0.041 and P=0.022, respectively). The TT genotype in ATF3 rs3125289 had significantly lower risk of estrogen receptor (ER), progesterone receptor (PR) negative, and human epidermal growth factor receptor 2 (HER2) positive status ( P=0.023, P=0.046, and P=0.040, respectively). In both, univariate and multivariate Cox analysis, TXNRD2 rs1139793 GG genotype vs. GA+AA was a negative prognostic factor for disease-free survival (multivariate hazard ratio (HR) 2.248; P=0.025) and overall survival (multivariate HR 2.248; P=0.029). The ATF3 rs11119982 CC genotype in the genotype model was a negative prognostic factor for disease-free survival (multivariate HR 5.878; P=0.006), metastasis-free survival (multivariate HR 4.759; P=0.018), and overall survival (multivariate HR 3.280; P=0.048). Conclusion: Our findings suggest that P21 rs1801270 is associated with lymph node metastasis and larger tumor size, and ATF3 rs3125289 is associated with ER, PR, and HER2 status. Two potential, novel, early-stage breast cancer survival biomarkers, TXNRD2 rs1139793 and ATF3 rs11119982, were detected. Further investigations are needed to confirm the results of the current study.

IntroductionComprehensive updated information on cervical cancer surgical treatment in Europe is scarce.ObjectiveTo evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database.MethodsThe SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified.ResultsThe mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m2 (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0–84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation.ConclusionsIn this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.
