Objective. The incidence of pancreatic cancer is estimated to be 48,960 in 2015 in the US and projected to become the second and third leading causes of cancer-related deaths by 2030. The mean costs in 2015 may be assumed to be $79,800 per patient and for each resection $164,100. Attempt is made to evaluate the results over the last 80 years, the number of survivors, and the overall survival percentage. Methods. Altogether 1230 papers have been found which deal with resections and reveal survival information. Only 621 of these report 5-year survivors. Reservation about surgery was first expressed in 1964 and five-year survival of nonresected survivors is well documented. Results. The survival percentage depends not only on the number of survivors but also on the subset from which it is calculated. Since the 1980s the papers have mainly reported the number of resections and survival as actuarial percentages, with or without the actual number of survivors being reported. The actuarial percentage is on average 2.75 higher. Detailed information on the original group (TN), number of resections, and actual number of survivors is reported in only 10.6% of the papers. Repetition occurs when the patients from a certain year are reported several times from the same institution or include survivors from many institutions or countries. Each 5-year survivor may be reported several times. Conclusion. Assuming a 10% resection rate and correcting for repetitions and the life table percentage the overall actual survival rate is hardly more than 0.3%.

The generally accepted staging for chronic lymphocytic leukemia (CLL) suggested by K. Rai and J. Binet allows calculating the median survival depending on the size of the tumor mass. However, in real clinical practice, the overall survival rate may differ significantly from the calculated median. Thus, the search for parameters affecting the overall survival rate of CLL patients is really relevant. The aim of the study was to assess general clinical parameters as predictors of survival in CLL patients. Materials and Methods. The authors examined 60 CLL men (stages A–C according to Binet) with known overall survival rate. Data mining was used to identify significant factors affecting the overall survival in such patients. Patients were divided into two non-overlapping classes: K1 (actual survival was less than the predicted median survival) and K2 (actual survival was more or equal to the predicted median survival). Results. The most significant differences between the classes were obtained for glomerular filtration rate. If the parameter value is more than 76.5 ml/min/1.73 m2, we can say that the patient will overcome the median survival for the corresponding CLL stage according to Binet. Otherwise, the overall survival of a CLL patient will be less than the estimated one. Conclusion. If during diagnosing glomerular filtration rate of a CLL patient is more than 76.5 ml/min/1.73 m2, it can be considered as a predictor of overcoming the median survival according to Binet. The results of the studies obtained are patented. Patent RU 2725877 C1, July 7, 2020. Keywords: overall survival in CLL patients, men, glomerular filtration rate, data mining. Общепризнанные системы стадирования хронического лимфолейкоза (ХЛЛ) К. Rai и J. Binet позволяют рассчитать медиану выживаемости пациента в зависимости от величины опухолевой массы. Однако в реальной клинической практике параметр общей выживаемости пациента может значимо отличаться от расчетной медианы. Ввиду этого поиск параметров, влияющих на показатель общей выживаемости пациентов с ХЛЛ, представляет особую актуальность. Цель исследования – оценить возможность использования общеклинических параметров в качестве предикторов выживаемости больных ХЛЛ. Материалы и методы. Ретроспективно проанализированы данные 60 мужчин с ХЛЛ стадии A–C по Binet c известной общей выживаемостью. Для выявления значимых факторов, влияющих на общую выживаемость пациентов, использовали метод интеллектуального анализа данных. Пациенты были разделены на два непересекающихся класса: K1 (фактическая выживаемость меньше прогнозируемой медианы выживаемости) и K2 (фактическая выживаемость больше или равна прогнозируемой медиане выживаемости). Результаты. Наиболее значимые различия между классами были получены по показателю скорости клубочковой фильтрации. При значении параметра более 76,5 мл/мин/1,73 м2 можно говорить о том, что пациент преодолеет расчетные данные медианы выживаемости для соответствующей стадии ХЛЛ по Binet. В противном случае общая выживаемость пациента ХЛЛ будет меньше расчетной. Выводы. Наличие у пациента с ХЛЛ на момент постановки диагноза скорости клубочковой фильтрации более 76,5 мл/мин/1,73 м2 можно рассматривать в качестве предиктора преодоления расчетного параметра медианы выживаемости по Binet. Результаты полученных исследований запатентованы. Патент RU 2725877 C1 от 7.07.2020. Ключевые слова: общая выживаемость при ХЛЛ, мужчины, скорость клубочковой фильтрации, интеллектуальный анализ данных.

Abstract Background An increasing number of extremely preterm (EP) infants have survived worldwide. However, few data have been reported from China. This study was designed to investigate the short-term outcomes of EP infants at discharge in Guangdong province. Methods A total of 2051 EP infants discharged from 26 neonatal intensive care units during 2008–2017 were enrolled. The data from 2008 to 2012 were collected retrospectively, and from 2013 to 2017 were collected prospectively. Their hospitalization records were reviewed. Results During 2008–2017, the mean gestational age (GA) was 26.68 ± 1.00 weeks and the mean birth weight (BW) was 935 ± 179 g. The overall survival rate at discharge was 52.5%. There were 321 infants (15.7%) died despite active treatment, and 654 infants (31.9%) died after medical care withdrawal. The survival rates increased with advancing GA and BW (p < 0.001). The annual survival rate improved from 36.2% in 2008 to 59.3% in 2017 (p < 0.001). EP infants discharged from hospitals in Guangzhou and Shenzhen cities had a higher survival rate than in others (p < 0.001). The survival rate of EP infants discharged from general hospitals was lower than in specialist hospitals (p < 0.001). The major complications were neonatal respiratory distress syndrome, 88.0% (1804 of 2051), bronchopulmonary dysplasia, 32.3% (374 of 1158), retinopathy of prematurity (any grade), 45.1% (504 of 1117), necrotizing enterocolitis (any stage), 10.1% (160 of 1588), intraventricular hemorrhages (any grade), 37.4% (535 of 1431), and blood culture-positive nosocomial sepsis, 15.7% (250 of 1588). The multivariate logistic regression analysis indicated that improved survival of EP infants was associated with discharged from specialist hospitals, hospitals located in high-level economic development region, increasing gestational age, increasing birth weight, antenatal steroids use and a history of premature rupture of membranes. However, twins or multiple births, Apgar ≤7 at 5 min, cervical incompetence, and decision to withdraw care were associated with decreased survival. Conclusions Our study revealed the short-term outcomes of EP infants at discharge in China. The overall survival rate was lower than the developed countries, and medical care withdrawal was a serious problem. Nonetheless, improvements in care and outcomes have been made annually.

Background and Aims: Pancreatic cancer has the lowest survival rate of all cancers (4%), and it accounts for 1.9% of new cancer cases in Hong Kong. Combined treatment with Chinese herbal medicine (CHM) and Western medicine has yielded promising results, leading to improved prognosis and overall survival. This retrospective case series aimed to illustrate the improved survival and quality of life outcomes of pancreatic cancer patients administered CHM based on traditional Chinese medicine theory. Methods: To investigate the effectiveness of CHM in prolonging overall survival, 182 patients diagnosed with pancreatic cancer who received CHM treatment were observed from 2005 to 2015. Results: One hundred eighty-two pancreatic cancer patients were treated with CHM; 21 patients died. The mean and median survival of these patients were 29.6 and 15.2 months, respectively; the 1-year survival rate was 76% (range = 4 months to 9 years). These results are better than those reported in patients treated with Western medicine, suggesting the need for further study of CHM. Conclusion: A superior clinical outcome may be obtained with CHM treatment. The case series illustrates the potential benefits and safety issues of CHM in pancreatic cancer patients that could be relevant for developing strategies to increase individualization of pancreatic cancer treatment and improve survival. This study may facilitate interprofessional communication and improved clinical management of pancreatic cancer patients.

280 Background: Multimodality therapy has been advocated for borderline resectable pancreatic cancer (BRCP); however, specific regimens vary widely by institution. Outcomes of these interventions need to be examined to inform future investigation of the optimal therapy for these patients. This study represents the experience of multimodality therapy for BRPC at an NCI designated cancer center. Methods: We identified all patients (pts) with operable pancreatic ductal adenocarcinoma (PDA) from 2006 to 2011. Patients were divided into two groups: resectable group and BRPC group as per the NCCN and AHPBA consensus guidelines. Primary outcomes were resection rate, microscopic negative margin (R0) resection rate, overall survival (OS), and disease free survival (DFS). Fisher's exact and chi-square were used for group comparison while Kaplan-Meier estimates was used for survival analysis. Results: 160pts were identified with operable PDA. 100 (63%) pts had resectable tumors, and 60 (37%) pts had borderline resectable tumors. Neoadjuvant therapy (NT) was administered to 0% in the group with resectable tumors, and 100% in the group with borderline resectable tumors. The resection rate was 100% in pts with resectable tumors and 58% in pts with borderline resectable tumors. R0 resection rates were 80% in the resectable tumors and 97% in the borderline resectable tumors following NT. Perioperative mortality was <1% (1/125) for resectable tumors and 0% in borderline resectable tumors. Median OS was 22.6 months (m) for pts that had resectable tumors and 13.9m for all pts with borderline resectable tumors (p=0.017); however, the median OS for resected pts with borderline resectable tumors was 21.5m (p=0.6). Improved DFS was seen in patients with resectable tumors when compared with resected borderline resectable tumors (15 vs. 9.5m; p=0.04). Conclusions: Multimodality therapy leads to high rates of R0 resections in borderline resectable pancreatic cancer; however 42% of patients progressed during NT. The overall survival for patients with resected borderline resectable pancreatic cancer following NT is similar to patients who undergo resection for resectable pancreatic cancer.

e15052 Background: Pancreatic resection is the only known curative option for pancreatic adenocarcinoma. Resection has been previously reported to be underutilized in patients with early stage disease. To develop a better understanding of this issue and control for treatment selection factors, we examined the relationship between geographic area resection rates and survival in patients with stage I/II pancreatic cancer. Methods: We queried Surveillance, Epidemiology, and End Results (SEER) data for patients with stage I/II cancer of the pancreatic head diagnosed from 2004-2009. We excluded patients with less than 3mo survival. Resection rates were calculated within Health Service Areas (HSAs) across all 18 SEER regions. Resection rate was defined as the number of patients who had an operation divided by the total number diagnosed with early stage pancreatic cancer. Multivariate Cox regression was used to estimate the overall survival effect of HSA rates while controlling for age, gender, marital status, poverty level, education, and AJCC stage. Results: 8,323 patients with stage I (n=1,454) and stage II (n=6,869) disease were analyzed. Pancreatectomy was performed in 476 patients (32.7%) with stage I disease and 3,846 (56.0%) with stage II disease. HSA resection rates were arranged into five groups (quintiles) which ranged from 42.7 to 65.7% (Table). Across the quintiles, median overall survival increased from 11 to 14 months, suggesting a positive association with resection rate. Multivariate analysis revealed that for every 10.00% increase in resection rate, the risk of overall death decreased by 5.26% (p<0.001). Conclusions: Patients with early stage pancreatic cancer who live in areas with higher resection rates have longer average survival times. Because geography should not influence treatment response, we conclude that efforts to raise resection rates should increase survival times in patients for whom there is uncertainty about the risk/benefits of resection.

Objective: To review our experience with full-term neonates with necrotizing enterocolitis (NEC) and to compare its characteristics to those published in the literature.Design: Retrospective review of all neonates born after 35 weeks of gestation managed in Reunion Island for NEC from 2000 to 2012.Results: Among the 217 diagnosed NEC, 27 patients (12.4%) were full term neonates, who were born at a mean gestational age of 36.8 ±1.7 weeks. The mean onset of the disease was 12.1±11.2 days after birth. Twenty patients had underlying causes (15 organic pathologies of the child, 3 isolated maternal disease, and 2 infections); 7 had idiopathic NEC. Surgery was required in 12 patients (37.5%) at 23.2±20 days after birth. NEC affected most of the time the colon (n=6) and the rectum (n=3). Overall survival rate was 88.8% (24/27). Two patients required partial non-enteral nutrition for1.3 and 2.1 years.Conclusions: NEC in full term neonates is a rare pathology. The onset of the disease in our experience was slightly later than described in the literature, but remains earlier than in the premature population. In some cases, no obvious cause can be found, suggesting a different pathogenesis. Further investigations are required in order to better understand this pathology. The goal will be to find measures to reduce global mortality.

PURPOSE Preoperative chemoradiotherapy may improve the radical resection rate for resectable or borderline resectable pancreatic cancer, but the overall benefit is unproven. PATIENTS AND METHODS In this randomized phase III trial in 16 centers, patients with resectable or borderline resectable pancreatic cancer were randomly assigned to receive preoperative chemoradiotherapy, which consisted of 3 courses of gemcitabine, the second combined with 15 × 2.4 Gy radiotherapy, followed by surgery and 4 courses of adjuvant gemcitabine or to immediate surgery and 6 courses of adjuvant gemcitabine. The primary end point was overall survival by intention to treat. RESULTS Between April 2013 and July 2017, 246 eligible patients were randomly assigned; 119 were assigned to preoperative chemoradiotherapy and 127 to immediate surgery. Median overall survival by intention to treat was 16.0 months with preoperative chemoradiotherapy and 14.3 months with immediate surgery (hazard ratio, 0.78; 95% CI, 0.58 to 1.05; P = .096). The resection rate was 61% and 72% ( P = .058). The R0 resection rate was 71% (51 of 72) in patients who received preoperative chemoradiotherapy and 40% (37 of 92) in patients assigned to immediate surgery ( P < .001). Preoperative chemoradiotherapy was associated with significantly better disease-free survival and locoregional failure-free interval as well as with significantly lower rates of pathologic lymph nodes, perineural invasion, and venous invasion. Survival analysis of patients who underwent tumor resection and started adjuvant chemotherapy showed improved survival with preoperative chemoradiotherapy (35.2 v 19.8 months; P = .029). The proportion of patients who suffered serious adverse events was 52% versus 41% ( P = .096). CONCLUSION Preoperative chemoradiotherapy for resectable or borderline resectable pancreatic cancer did not show a significant overall survival benefit. Although the outcomes of the secondary end points and predefined subgroup analyses suggest an advantage of the neoadjuvant approach, additional evidence is required.

Introduction: Despite improvements in radiation therapy, chemotherapy and surgical procedures over the last 30 years, pancreatic cancer 5-year survival rate remains at 9%. Reduced stroma permeability and heterogeneous blood supply to the tumour prevent chemoradiation from making a meaningful impact on overall survival. Hypoxia-activated prodrugs are the latest strategy to reintroduce oxygenation to radioresistant cells harbouring in pancreatic cancer. This paper reviews the current status of photon and particle radiation therapy for pancreatic cancer in combination with systemic therapies and hypoxia activators. Methods: The current effectiveness of management of pancreatic cancer was systematically evaluated from MEDLINE® database search in April 2019. Results: Limited published data suggest pancreatic cancer patients undergoing carbon ion therapy and proton therapy achieve a comparable median survival time (25.1 months and 25.6 months, respectively) and 1-year overall survival rate (84% and 77.8%). Inconsistencies in methodology, recording parameters and protocols have prevented the safety and technical aspects of particle therapy to be fully defined yet. Conclusion: There is an increasing requirement to tackle unmet clinical demands of pancreatic cancer, particularly the lack of synergistic therapies in the advancing space of radiation oncology.
