Population Based Study

Background: Incidence of Aplastic Anemia (AA) in Asia tends to be higher than in western countries, but contemporary real-world incidence and outcomes of AA in Asia remain limited. This study aimed to explore the incidence across the country regions and to evaluate the patient outcomes according to age, the severity of disease, and treatment modalities. Method: This is a prospective multicenter nationwide population-based observational study of patients with AA aged over 15 years old, diagnosed between August 1st, 2014 to July 31st, 2016, with a longitudinal follow-up period over 2 years, from 30 medical centers. Patients with suspected hypocellular MDS and congenital bone marrow failure syndrome were excluded. Results: During the study period of 2 years, there were 348 newly diagnosed patients with aplastic anemia, giving the annual incidence of 4.6 per million inhabitants. There was a higher annual incidence of severe (SAA) and very severe aplastic anemia (VSAA) (3.8 per million) than non-severe aplastic anemia (NSAA) (0.8 per million). The incidence was greater among older patients with a peak incidence in patients aged 60-89 years old. (Figure 1) There was a high variation in the geographic incidences across country regions, ranging from 2.6 to 6.6 per million per year. (Figure 2) The 2-year overall survival (OS) for NSAA, SAA, and VSAA were 65.5%, 49.3%, and 20.1%, respectively (P < 0.001). Patients aged older than 60 years had the worst OS (42.6% as compared with 47.7% for the age 41-60 years and 64.5% for the age 15-40 years, P = 0.002). Among patients with SAA and VSAA (n = 280), the overall response rate (ORR) among patients treated with rabbit anti-thymocyte globulin and/or cyclosporin A (rATG±CsA) was significantly superior than those treated with CsA-based therapy and those treated with anabolic steroid (44.4% vs. 36.4% and 31.2%, respectively, P < 0.001). Among evaluable patients, ORR after the 1st treatment with rATG±CsA at 3, 6, 12 and 24 months were 23.9%, 43.8%, 68.4% and 89.2%, respectively. The 2-year OS among SAA/VSAA patients treated with rATG±CsA, CsA-based therapy, and anabolic steroid were 54.8%, 54.5%, and 37.6% (P = 0.037), respectively (Figure 3). From multivariate analysis, age > 60 years (HR 1.63, 95%CI, 1.14-2.33, P = 0.007), VSAA (HR 2.24, 95% CI, 1.45-3.46, P < 0.001) and not receiving immunosuppressive therapy or anabolic steroid (HR 4.96, 95%CI, 2.88-8.54, P <0.001), were independently associated with inferior OS among patients with SAA/VSAA. Conclusion: The incidence rate of AA in Thailand from this contemporary nationwide population-based study is high, especially in the elderly. Patients treated with rATG±CsA had superior survival than those receiving anabolic steroid. The real-world outcome of patients with SAA/VSAA, especially in those aged over 60 years, is substantially poor. Figure 1 Disclosures No relevant conflicts of interest to declare.

Few provinces in China have recently conducted population-based surveys on tuberculosis (TB) awareness at the provincial level. Hence, we conducted a population-based, cross-sectional study to evaluate the level of awareness of TB knowledge among residents of Zhejiang Province, China from October 2018 to December 2018. A total of 7174 individuals were randomly selected to participate in this survey. The rate of awareness of key information on TB was found to be 48.0%. The study’s participants exhibited a good understanding of the transmission route (80.8%), curable outcome (78.3%), and designated treatment sites (67.0%) of TB. The rate of awareness of suspicious TB symptoms (36.1%) and the relief policy on diagnosis and first-line therapeutic drugs (38.0%) were found to be relatively low among the respondents. People living in rural areas, those who were less educated, and students all showed a low level of awareness of key knowledge about TB. In conclusion, residents in Zhejiang Province generally lacked key information about TB, which is not conducive to the early detection and treatment of TB. Corresponding efforts should be made for different groups of people to achieve favorable effects on the prevention and control of TB.

Abstract Abstract 1611 Introduction: For many T-cell lymphoma (TCL) patients (pts), current treatment strategies are largely ineffective. In particular, pts failing first line therapy are expected to have a dismal outcome but little is known about them. The purpose of this population-based study was to establish the outcome of TCL pts following relapse/progression. Material and methods: All TCL pts diagnosed in the province of Modena, Italy between January 1, 1997 and December 31, 2010 were identified from the archives of the Modena Cancer Registry that covers a population of approximately 600.000 people. Additional data on disease characteristics, treatment modalities, together with response assessments and outcome were actively retrieved and collected. Results: A total of 146 TCL pts were initially identified, and 18 excluded because of missing data; therefore 128 were available for the present analysis. The most common subtypes were Peripheral T-cell lymphoma not otherwise specified in 46 pts (36%), Anaplastic large T-cell lymphoma in 46 patients (36%) Angioimmunoblastic T-cell lymphoma in 15 (12%), and other subtypes in 21 (16%). The male to female ratio (M/F) for the entire population was 1.7 and the median age was 64 years (16–90). A total of 100 (78%) pts received initial treatment within 3 months of their diagnosis: 74 received combination chemotherapy (CT), 9 received radiation therapy (RT) only, 10 underwent surgery and 7 were addressed to high dose therapy and autologous stem cell transplant (ASCT) as part of initial therapy. Among the remaining 28 patients, 24 (19%) died within 3 months of their diagnosis and 4 (3%) received only palliative therapy because of their comorbidities. The majority of pts received anthracyclines (ADM) containing regimens as part of their initial therapy (71/74, 96%). At the end of first line treatment, 59 (59%) pts achieved complete remission (CR), 13 pts partial remission (PR), 8 pts stable disease (SD) and 20 cases had disease progression (PD). Overall, 59 pts presented relapse/progression; 23 (39%) of them died before receiving any salvage treatment, 14 pts received DHAP (7 of whom were subsequently addressed to ASCT), 8 received gemcitabine-containing regimens, 6 received ADM containing regimes and 8 other CT regimens; 2 patients were treated with RT. At a median follow-up for living patients after relapse/progression of 28 months (range 9–111 months), 49 patients died, and the cause of death was found to be lymphoma progression in all of them. The median overall survival (OS) following relapse/progression was 1.9 months. Among the 36 pts that received salvage treatment median OS was not reached for those who received ASCT and was 4.5 months for those who received conventional dose salvage treatment (p=0.003). A Cox regression analysis was performed in order to identify prognostic factors among these 59 pts: age at relapse (≥60 years, HR=2.35, CI95% 1.04–5.28, P=0.038) and advanced stage (HR=3.24, 1.31–7.98) were associated with a higher risk of death and salvage treatment ASCT was associated with a better survival (HR=0.04, IC95% 0.006–0.36). No other clinical characteristic (gender, histology, LDH and performance status) at diagnosis was associated with higher risk of death among relapsing/progressing patients. Conclusion: In the general population, outside clinical trials, the outcome of TCL pts is dramatically poor. First, about 20% of the whole cohort is not able to receive any kind of therapy mainly due to early death; second, the rate of pts failing first line therapy that could not receive any salvage therapy rose to 39%. As a result, progression during initial therapy or relapse after first line treatment entails a very dismal prognosis with less than 2 months of median survival. Only a few patients that could receive ASCT after relapse had promising chances of long lasting remission. Based on the results of this population based study, it is evident that there is urgent need for novel agents to be offered to TCL pts requiring second line treatment.

Abstract Background In current guidelines, thiopurines are still recommended as first-line maintenance therapy for patients with Crohn’s disease (CD). Due to their lack of immunogenicity, oral administration route and low costs, thiopurines are an attractive first-line treatment option. However, in recent studies the position of thiopurine monotherapy in CD has been questioned as a result of relatively lower overall effectiveness rates compared to ulcerative colitis. Real-world long-term effectiveness data substantiating the use and position of thiopurines in CD management remain sparse. We assessed long-term effectiveness of thiopurine monotherapy in CD using the population-based IBD South-Limburg (IBDSL) cohort. Methods All CD patients in the IBDSL cohort starting thiopurine monotherapy as first-line maintenance therapy between 1991–2014 were included. Thiopurine monotherapy was defined effective if either: (1) no escalation to biological treatment, (2) no course of corticosteroids, (3) no resective surgery or, (4) no hospitalization for active disease was required whilst on thiopurine treatment. Patients with early treatment discontinuation (i.e. <3 months) were identified, including reason of discontinuation. Long-term effectiveness was assessed adjusting for differences in follow-up between patients using Kaplan-Meier analysis. Potential risk factors for therapy failure were identified using Cox regression. Results In total, 643/1162 (55.3%) CD patients (median follow-up: 8.5 years IQR 5.0–13.2) received first-line thiopurine monotherapy after a median of 9.7 months (IQR 3.2–31.3) after diagnosis. Therapy was discontinued within three months in 164 patients (25.5%), mainly due to adverse events [Figure 1]. Thiopurine monotherapy was effective for the duration of treatment in 229/479 (35.6%) patients, corresponding to estimated effectiveness rates of 62.9%, 43.9% and 31.2% after 1, 5 and 10 years, respectively [Figure 1–2]. No significant difference in effectiveness was observed after stratifying for era of thiopurine initiation (pre-biological (1991–1998) vs. biological (>1999) era, p=0.84). Factors associated with thiopurine failure were stricturing disease (aHR 1.41, 95%CI 1.01–1.96) and upper GI involvement (aHR 1.52, 95%CI 1.02–2.28) at diagnosis. During follow-up, 40/229 patients with a durable response discontinued treatment due to quiescent disease. Of these, 35 patients (87.5%) remained without treatment 24 months after discontinuation. Conclusion Real-world data from this population-based study demonstrate that thiopurine monotherapy remains an effective and durable first-line treatment option for CD, even in the biological era. These results should be considered in the ongoing discussion regarding the position of thiopurine therapy.

Most randomized trials for acute promyelocytic leukemia (APL) have investigated highly selected patients under idealized conditions, and the findings need to be validated in the real world. We conducted a population-based study of all APL patients in Zhejiang Province, China, with a total population of 82 million people, to assess the generalization of all-trans retinoic acid (ATRA) and arsenic as front-line treatment. The outcomes of APL patients were also analyzed. Between January 2015 and December 2019, 1,233 eligible patients were included in the final analysis. The rate of ATRA and arsenic as front-line treatment increased steadily from 66.2% in 2015 to 83.3% in 2019, with no difference among the size of the center (≥5 or <5 patients per year, p = 0.12) or age (≥60 or <60 years, p = 0.35). The early death (ED) rate, defined as death within 30 days after diagnosis, was 8.2%, and the 3-year overall survival (OS) was 87.9% in the whole patient population. Age (≥60 years) and white blood cell count (>10 × 109/L) were independent risk factors for ED and OS in the multivariate analysis. This population-based study showed that ATRA and arsenic as front-line treatment are widely used under real-world conditions and yield a low ED rate and a high survival rate, which mimic the results from clinical trials, thereby supporting the wider application of APL guidelines in the future.
