ABSTRACTEffective data sharing is key to accelerating research that will improve the precision of diagnoses, efficacy of treatments and long-term survival of pediatric cancer and other childhood catastrophic diseases. We present St. Jude Cloud (https://www.stjude.cloud), a cloud-based data sharing ecosystem developed via collaboration between St. Jude Children’s Research Hospital, DNAnexus, and Microsoft, for accessing, analyzing and visualizing genomic data from >10,000 pediatric cancer patients, long-term survivors of pediatric cancer and >800 pediatric sickle cell patients. Harmonized genomic data totaling 1.25 petabyes on St. Jude Cloud include 12,104 whole genomes, 7,697 whole exomes and 2,202 transcriptomes, which are freely available to researchers worldwide. The resource is expanding rapidly with regular data uploads from St. Jude’s prospective clinical genomics programs, providing public access as soon as possible rather than holding data back until publication. Three interconnected apps within the St. Jude Cloud ecosystem—Genomics Platform, Pediatric Cancer Knowledgebase (PeCan) and Visualization Community—provide a unique experience for simultaneously performing advanced data analysis in the cloud and enhancing the pediatric cancer knowledgebase. We demonstrate the value of the St. Jude Cloud ecosystem through use cases that classify 48 pediatric cancer subtypes by gene expression profiling and map mutational signatures across 35 subtypes of pediatric cancer.

Abstract Background and Study Aims The exact reason of long-term survival in glioblastoma (GBM) patients has remained uncertain. Molecular parameters in addition to histology to define malignant gliomas are hoped to facilitate clinical, experimental, and epidemiological studies. Material and Methods A population of GBM patients with similar clinical characteristics (especially similar resectability) was reviewed to compare the molecular variables between poor (overall survival [OS] < 18 months, control cohort) and long-term survivors (overall survival > 36 months, OS-36 cohort). Results Long-term GBM survivors were younger. In the OS-36 cohort, the positive rate of isocitrate dehydrogenase (IDH) mutation was very low (7.69%, 3/39) and there was no statistical difference in OS between IDH mutant and wild-type patients. The results of 1p/19q codeletions are similar. Besides, there were no significant difference in MGMT promoter methylation, telomerase reverse transcriptase (TERT) promoter mutation, and TP53 mutations between OS-36 cohort and control cohort. Conclusions No distinct markers consistently have been identified in long-term survivors of GBM patients, and great importance should be attached to further understand the biological characteristics of the invasive glioma cells because of the nature of diffuse tumor permeation.

Purpose To determine the incidence of potentially treatment-related mortality in long-term survivors of testicular seminoma treated by orchiectomy and radiation therapy (XRT). Patients and Methods From all 477 men with stage I or II testicular seminoma treated at The University of Texas M.D. Anderson Cancer Center (Houston, TX) with postorchiectomy megavoltage XRT between 1951 and 1999, 453 never sustained relapse of their disease. Long-term survival for these 453 men was evaluated with the person-years method to determine the standardized mortality ratio (SMR). SMRs were calculated for all causes of death, cardiac deaths, and cancer deaths using standard US data for males. Results After a median follow-up of 13.3 years, the 10-, 20-, 30-, and 40-year actuarial survival rates were 93%, 79%, 59%, and 26%, respectively. The all-cause SMR over the entire observation interval was 1.59 (99% CI, 1.21 to 2.04). The SMR was not excessive for the first 15 years of follow-up: SMR, 1.30 (95% CI, 0.93 to 1.77); but beyond 15 years the SMR was 1.85 (99% CI, 1.30 to 2.55). The overall cardiac-specific SMR was 1.61 (95% CI, 1.21 to 2.24). The cardiac SMR was significantly elevated only beyond 15 years (P < .01). The overall cancer-specific SMR was 1.91 (99% CI, 1.14 to 2.98). The cancer SMR was also significant only after 15 years of follow-up (P < .01). An increased mortality was evident in patients treated with and without mediastinal XRT. Conclusion Long-term survivors of seminoma treated with postorchiectomy XRT are at significant excess risk of death as a result of cardiac disease or second cancer. Management strategies that minimize these risks but maintain the excellent hitherto observed cure rates need to be actively pursued.

Glioblastoma multiforme is the most malignant tumor of the glial series. The average survival of patients with this tumor ranges from 6 to 12 months. The case of a patient who survived for more than 11 years after diagnosis of a temporal-occipital glioblastoma which was treated with surgery, radiotherapy and chemotherapy is described. The authors deduce that among patients with glioblastoma multiforme (GM), those with a long disease-free interval after initial diagnosis who undergo multimodal therapy, including aggressive tumor removal, are the most likely long-term survivors (LS). Other factors which appeared to be related to longer survival were younger age and high Karnofsky scores.

335 Background: Based on the clinical data in Japanese renal cell carcinoma (RCC) patients who underwent cytokine therapy (Naito et al, Eur Urol 2010), the overall survival (OS) of these patients has been considered to be better than that of Caucasian patients. We identified long-term survivors among a cohort of 473 metastatic RCC patients, and explored clinical predictors of OS in these patients. Methods: Between 1995 and 2005, 473 patients with metastatic RCC were the subjects of this retrospective analysis. Three hundred sixty-one (76%) patients received IFN-α and no patient did molecular-targeted drugs. The patients with survival times of greater than 5 years after the development of metastases were identified as long-term survivors. Multiple logistic regression analysis was performed to evaluate the impact of clinical variables potentially influencing OS. Results: Median OS for all patients was 22.3 months (95%CI 18.7-27.6), the estimated 5-year survival rate was 27.4% (95% CI 22.9-31.9). Sixty-eight patients (14.4%) among 473 patients were identified as long-term survivors. Twenty-six (38%) had metastases at diagnosis of kidney cancer, 3 (4%) and 11 (16%) had liver mets and bone mets, respectively. According to MSKCC risk classification, 19 (28%), 28 (41%), and 6 (9%) were classified as favorable, intermediate, and poor risk, respectively. All patients had undergone prior nephrectomy, and 40 (59%) underwent metastatectomy. Multiple logistic regression analysis from all patients identified metastatectomy (HR 5.0; 95%CI 2.7-9.5) and MSKCC risk group (HR 3.7; 95%CI 1.5-9.1) as adverse prognostic factors for long-term OS. Conclusions: Selected patients with metastatic RCC who can undergo metastatectomy have a good opportunity for long-term survival, especially those with favorable or intermediate risk classified by MSKCC risk classification. No significant financial relationships to disclose.

Regardless of how one defines survivorship, more than 10 million individuals in the United States have been treated for a malignant disease; about 250,000 were younger than 21 years of age at diagnosis. Thirty years ago, pediatric oncologists recognized that children with cancer might be cured by adding chemotherapy to surgery and radiation. Studies were then begun of complications that could reduce survival or the quality of survival, and that might be associated with previous therapy. The complications were termed late effects, and studies focused on patients who were likely to be cured, or less likely to succumb to the original cancer than they were to experience disabilities. Clinical trials tested whether changes in therapy to reduce complications could maintain the same excellent survival rates. During the last 20 years, articles detailing late effects and the relationship between therapy and outcome have been published. This article reviews the progress made in understanding the outcomes reported and the efforts made to improve the quality of long-term survival for children and adolescents. Several questions remain regarding the long-term complications of therapy. Clinicians need more data regarding the effects of aging to guide them in managing former patients. Caregivers and pediatric cancer survivors who are now adults seek the optimal venue in which to receive care as independent adults. In addition, medical oncologists need to determine whether the models for research and clinical care of survivors created in pediatric oncology can be applied to survivors of adult-onset cancer.

Abstract BackgroundCytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) improves survival in selected patients with peritoneal metastasis (PM) from colorectal cancer (CRC). However, little has been reported on characteristics and clinical course of long-term survivors with CRC-PM beyond 5 years. The objective of this study was to describe the clinical and oncological features affecting long-term survival of CRC-PM after comprehensive treatment.MethodsBetween January 1990 and April 2015, CRC-PM patients who underwent CRS with or without HIPEC in two Japanese tertiary hospitals and who survived longer than 5 years after the first CRS for PM were retrospectively investigated. Clinicopathological parameters and therapeutic details involved in long-term survival were reviewed. Patients were defined as cured if the recurrence-free interval was > 5 years after the last operation for metastases.ResultsThirty-three patients with a median peritoneal cancer index (PCI) of 4 (range, 1–27) were included. Complete cytoreduction was achieved in all 33 patients, and none had a rectal primary. Recurrence was observed in 19 patients (57.6%) at a median of 2.6 (range, 0.7–7.4) years. Sixteen patients (48.5%) were considered cured, of whom two never developed re-recurrence after the second surgery. The median PCI of cured group was 2 (range, 1–8).ConclusionsLong-term survival and cure were obtained after CRS in selected patients with CRC-PM. Low PCI, complete cytoreduction, and non-rectal primary are associated with long-term survival and cure in PM from CRC.

Abstract Background: Actuarial survival based on the Kaplan–Meier method can overestimate actual long-term survival, especially among those with factors of poor prognosis. Patients with American Joint Committee on Cancer stage III soft tissue sarcoma (STS) represent a subset with a high risk of STS-specific mortality. Therefore, we aimed to characterize the clinicopathological characteristics associated with actual long-term survival in patients with stage III STS.Methods: We retrospectively reviewed 116 patients who underwent surgical resection for stage III STS with curative intent between March 2000 and December 2013. Long-term survivors (n = 61), defined as those who survived beyond 5 years, were compared with short-term survivors (n = 36), who died of STS within 5 years.Results: Multivariate logistic regression analyses showed that a tumor size <10 cm [odds ratio (OR) 3.95, p = 0.047], histological grade of 2 (OR 8.12, p = 0.004), and American Society of Anesthesiologists (ASA) score of 1 (OR 11.25, p = 0.001) were independently associated with actual 5-year survival. However, 66% of the long-term survivors exhibited factors of poor prognosis: 36% had a tumor size >10 cm and 48% had a histological grade of 3. Leiomyosarcoma (3 of 10) was negatively associated with actual long-term survival.Conclusions: Actual 5-year survival after resection of stage III STS was associated with tumor size, histological grade, and ASA score. However, majority of the actual 5-year survivors exhibit factors of poor prognosis, suggesting that resection should be offered for a chance of long-term survival in these patients.

Abstract Background Prognosis of metastatic colorectal cancer (mCRC) is poor and goal of treatment is mainly palliative unless there is limited metastatic disease which is surgically resectable. Here, we report a case series of long-term survivors treated predominantly with chemotherapy. Methods This is a single-center retrospective analysis of patients of mCRC. Records of metastatic colorectal cancer patients registered at Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi, between the year 2005 and 2015 were retrieved and reviewed. Inclusion criteria were patients who survived 5 years or more, treated mainly by chemotherapy, with either initial presentation as metastatic disease or those who progressed after initial surgery with or without adjuvant therapy. The details about the patient characteristics, treatment, and outcome were collected. The data were censored on September 30, 2020. Results Records of 370 mCRC patients were reviewed. Thirty-one patients with all the available details fulfilled the criteria for inclusion in the study. Median age was 53 years (range, 22–74 years). Sixteen were women (51.6%). Twenty-four (77%) were newly diagnosed cases with initial presentation as metastatic disease. Commonest site of primary was on the left (21, 67.6%) followed by right side and transverse colon in 5 patients each. Liver was the most common site of metastasis (n = 18, 58.06%). In metastatic setting, the most common chemotherapy regimen used in the first line was CAPOX (n = 11, 35.48%). Only three patients could undergo metastatectomy. Monoclonal antibodies could be used only in 14 patients. Median overall survival (OS) of this cohort is 81.6 months (95% confidence interval [CI], 69.73–117.9). Conclusion A small but significant proportion of mCRC patients may achieve and maintain durable responses and long term survival with use of combination of chemotherapy with or without biologics.

BackgroundMost lung cancer patients worldwide [stage IV nonsmall cell lung cancer (NSCLC)] have a poor survival: 25%–30% die &lt;3 months. Yet, of those surviving &gt;3 months, 10%–15% (70,000–105,000 new patients worldwide per year) survive (very) long. Surprisingly, little scientific attention has been paid to the question, which factors cause the good prognosis in these NSCLC stage IV long survivors. Therefore, “How long do I still have?” currently cannot be accurately answered. We evaluated in a large group of 737 stage IV NSCLC patients surviving 3.2–120.0 months, the accuracies of short- and long-term survival predictive values of baseline factors, radiotherapy (RT), platinum-based chemotherapy (PBT), and tyrosine kinase inhibitor targeted therapy (TKI-TT).MethodsThis is a noninterventional study of 998 consecutive first-onset stage IV NSCLC patients. A total of 737 (74%) survived 3.2–120.0 months, 47 refused RT, PBT, and TKI-TT. Single and multivariate survival analysis and receiver operating curve (ROC) analysis were used with dead of disease (DOD) or alive with disease (AWD) as endpoints.ResultsThe median survival (16.1 months) of 47 patients who refused PBT, RT, and TKI-TT was significantly worse than those with RT, PBT, and/or TKI-TT (23.3 months, HR = 1.60, 95% CI = 1.06–2.42, p = 0.04). Of these latter 690 patients, 42% were females, 58% males, median age 63 years (range 27–85), 1-, 2-, 5-, and 10-year survival rates were 74%, 49%, 16%, and 5%. In total, 16% were alive with disease (AWD) at the last follow-up. Pathology subtype (adenocarcinoma vs. all others), performance score, TNM substage, the number of PBT cycles and TKI-TT had independent predictive value. However, with the multivariate combination of these features, identification results of short-term nonsurvivors and long-term survivors were poor.ConclusionsIn stage IV NSCLC patients with &gt;3 months survival, baseline features, and systemic therapeutic modalities have strong survival predictive value but do not accurately identify short- and long-term survivors. The predictive value of other features and interventions discussed should be investigated in the worldwide very large group of stage IV NSCLC patients with &gt;3 months survival.

In this paper, a new long term survival model called Nadarajah-Haghighi model for survival data with long term survivors was proposed. The model is used in fitting data where the population of interest is a mixture of individuals that are susceptible to the event of interest and individuals that are not susceptible to the event of interest. The statistical properties of the proposed model including quantile function, moments, mean and variance were provided. Maximum likelihood estimation procedure was used to estimate the parameters of the model assuming right censoring. Furthermore, Bayesian method of estimation was also employed in estimating the parameters of the model assuming right censoring. Simulations study was performed in order to ascertain the performances of the MLE estimators. Random samples of different sample sizes were generated from the model with some arbitrary values for the parameters for 5%, 1:3% and 1:5% cure fraction values. Bias, standard error and mean square error were used as discrimination criteria. Additionally, we compared the performance of the proposed model with some competing models. The results of the applications indicates that the proposed model is more efficient than the models compared with. Finally, we fitted some models considering type of treatment as a covariate. It was observed that the covariate  have effect on the shape parameter of the proposed model.
