SummaryThe Multicentre Study Differentiated Thyroid Cancer (MSDS) collective represents a well defined group of patients with locally aggressive thyroid carcinomas (pT4; AJCC/UICC 1997). The aim of the present study was to compare the survival of patients with minimum and extensive extrathyroidal growth according to the new AJCC/UICC TNM staging system 2009. Patients, methods: The followup data of 347 patients were analysed. Patients were reclassified according to the current AJCC/UICC 2009 classification. The event-free and overall survival was evaluated using Kaplan-Meier analysis. In addition, postoperative complications and status of disease were documented. Results: 327 patients were assigned to stage pT3 and 20 patients to stage pT4a, respectively. Median follow-up was 6.1 years (range 0.04–9.8 years). 92.5% of patients reached complete remission. There were 7.8 % recurrences in the thyroid bed, in locoregional lymph nodes and/or in distant sites. The overall survival was >98% both in pT3 and pT4a patients (p = n. s.). In contrast, the event-free survival was significantly less favourable in pT4a patients (p < 0.001). Using multivariate analysis the following parameters were significant predictors of event-free survival: histological tumour type, degree of extrathyroidal extension and nodal metastasis (p < 0.05). Conclusions: The MSDS patients with locally aggressive differentiated thyroid cancer showed an excellent overall survival during a median follow-up of 6.1 years. According to the current AJCC/UICC 2009 classification, pT3 patients with minimal extra thyroidal extension revealed a significantly better event-free survival than pT4a patients with extensive extrathyroidal growth.

Beta 2 Microglobulin

Abstract The Durie-Salmon (DS) stage has been the gold standard for stratification of MM patients. However, the system does not contain beta-2 microglobulin (B2M) widely recognized as the single most powerful prognostic parameter. Recently, The Southwest Oncology Group (SWOG) staging system (Jacobson JL, et al. Br J Haematol122:441–50, 2003) and the International Staging System (ISS) (Greipp PR, et al. J Clin Oncol23:3412–20, 2005) utilizing B2M have been proposed. We aimed to evaluate whether the stage assessed at the time of ASCT by DS, SWOG, or ISS predict outcome following ASCT in patients with MM. Between November 1996 and December 2004, a total of 141 patients with MM who were treated with ASCT at 5 institutions in Korea were available for this analysis. The distribution of patients’ stage at ASCT by 3 staging systems was as Table 1. With a median follow-up of 20 months from ASCT, the median event-free survival (EFS) and overall survival (OS) were 16 months (95% confidence interval [CI], 11–21) and 56 months (95% CI, 38–74), respectively. The median survival of each stage group according to 3 staging systems at ASCT was as Table 2. Differences in EFS among the stage groups were not statistically significant. However, OS after ASCT was dependent on the SWOG stage at the time of ASCT and also significantly longer in patients with ISS stage I than others (NR vs. 39 months, P =.001). In this study, OS following ASCT was influenced by the stage according to SWOG or ISS, but not DS.

8Th Edition

Background: The 8th edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor-node-metastasis (TNM) staging system was released with major revisions. The purpose of this retrospective study was to investigate differences between the 7th and 8th editions of the AJCC/UICC TNM staging system and to compare the predictability of prognosis between the two staging systems with patients who underwent thyroidectomy for differentiated thyroid cancer (DTC) at a single institution. Methods: A total of 3238 patients underwent thyroid operation from January 2002 to December 2006 at Yonsei University Hospital (Seoul, Korea), of which 2294 with complete clinical data and sustained follow up were enrolled. Clinicopathologic features and TNM staging by applying the 7th and 8th editions of the AJCC/UICC were analyzed retrospectively by the complete review of medical charts and pathology reports of patients. Mean follow-up duration was 132.9 ± 27.9 months. Results: A significant number of T3 patients were downstaged to T1 (838, 36.5%) and T2 (122, 5.3%). After applying the 8th edition of the AJCC/UICC TNM staging system, the number of stage I patients increased significantly from 1434 (62.5%) to 2058 (89.7%), whereas numbers of stage III and IV patients decreased significantly from 644 (28.1%) to 33 (1.4%) and from 199 (8.7%) to 17 (0.7%), respectively. According to Kaplan–Meier survival analyses and values of the Harrell’s c-index and integrated area under the curve (iAUC), the 8th edition has significantly better predictive performance for disease-free survival (DFS) and disease-specific survival (DSS) than the 7th edition. Conclusions: A significant population was downstaged after applying the 8th edition of the AJCC/UICC TNM staging system, and the 8th edition provided significantly better accuracy in predicting DFS and DSS in patients with DTC.

Background:Sjögren’s Syndrome (SS) is a chronic systemic autoimmune disease of unknown etiology, carrying the highest lymphoma risk among autoimmune diseases, with significant impact on mortality and morbidity of patients.Objectives:To describe: i) the clinical phenotype of SS, ii) the histologic type, stage, treatment options regarding lymphomas and iii) the prognosis of patients with SS related lymphoproliferative disorders.Methods:Eight hundred and fifteen consecutive SS patients’ records from a single center fulfilling the 2016 ACR/EULAR were reviewed retrospectively for the purpose of this study. One hundred twenty-one patients with a diagnosis of non-Hodgkin Lymphoma (NHL) were identified and enrolled in the study population. Cumulative clinical, laboratory and histologic data were recorded and overall survival as well as event free survival curves were constructed using the Kaplan-Meier method. An event was defined as a disease progression, lymphoma relapse, treatment failure, histologic transformation, development of a 2nd lymphoma or death from any cause.Results:From 121 pSS patients with lymphoma the most common histologic type encountered was MALT lymphoma (92/121, 76,0%) followed by DLBCL (11/121, 9.0%) and NMZL (8/119, 6.6%). The remaining 10 patients had various lymphomas of B (follicular, lymphoplasmacytic, chronic lymphocytic leukemia} and T cell origin (peripheral T cell lymphoma not otherwise specified, primary cutaneous T cell lymphoma, angioimmunoblastic t-cell lymphoma). Permanent salivary gland enlargement (66.1%, 80/121), palpable purpura (34,7% 42/121), peripheral nervous involvement (9,9%, 12/121), interstitial lung disease (8,2%, 10/121) presence of serum cryoglobulins (38,7%, 43/111) and C4 hypocomplementemia (69,8% 81/116) present at least 1 year before the development of lymphoma were the main pSS related features. The median age at lymphoma diagnosis was 58 years old (range 29-82) while MALT lymphomas developed earlier compared to DLBCL from pSS diagnosis (8 vs 3 OR= 3.84, 95%CI: 0.29 to 10.46; p=0.0266). The commonest biopsy proven extranodal sites included the labial minor salivary (43,8% patients) and parotid glands (30,5%) while 11% of patients had more than 1 extranodal sites affected. Bone marrow involvement was evident in 24,3% of patients (29/119) while nodal involvement in 35,5% (42/118). The majority of patients (65%) had limited disease (stage I or II). A watch and wait therapeutic policy was chosen in 40 patients while the rest received rituximab with or without chemotherapy. The 10-year survival and event free rates were 79% and 45,5% for MALT lymphomas, 40,9% and 24,2% for DLBCL and 46% and 31% for NMZL respectively (Figure 1). The Mantel-Cox log-rank comparison of the overall survival curves revealed a statistically significant difference (p=0.0016) among lymphoma subtypes.Figure 1.Overall and event free survival of SS-associated lymphoma patients. A. Kaplan-Meier overall survival analysis. B. A Kaplan-Meier event free survival analysis.Conclusion:This is the largest single center series of SS- associated lymphoma patients, providing a detailed description of SS and lymphoma related features, combined with a 10-year survival and event free curves for the first time in the literature.Disclosure of Interests:None declared.

e19005 Background: CALGB 10403 is a pediatric-inspired ALL regimen that has recently been shown to have improved survival rates in adolescents and young adults with ALL when compared to historical outcomes with traditional adult ALL regimens (Stock et. al, 2019). Methods: This is a retrospective cohort study of ALL patients who received induction CALGB 10403 at Stanford University (both on and off trial), achieved CR1, and subsequently relapsed. Primary outcome of interest was event free survival from time of diagnosis. Events were defined as relapse or death. Secondary outcomes were overall survival and event free survival from first relapse. Patients were censored at time of last clinical follow up. Results: 25 patients met inclusion criteria and received front-line CALGB 10403 from April 2010 to September 2018. At the time of initial diagnosis median age was 30 years (range 18 – 39 years). 68% of patients were male. 48% of patients were overweight and 40% were obese. 76% of patients had precursor B cell ALL while 24% had T cell ALL. 12% had CNS disease at diagnosis. 36% of patients had WBC greater than 30k. 12% of patients had CRLF2 rearrangement. 12% of patients were MRD positive after first induction. 20% of patients received rituximab. Median event free survival time from diagnosis was 20 months (range 3 – 79 months) and median overall survival time was 53 months. Blinatumomab was the most common salvage therapy after 1st relapse, followed by inotuzumab. 15 patients (60%) achieved CR2, of which 4 (27%) were MRD positive after 2nd induction. 15 patients (60%) went to HSCT. Of the patients who achieved CR2, 8 relapsed for a second time. Median event free survival time after first relapse was 23 months. Survival 1 year after relapse was 60%. 11 of the 25 patients were alive at last follow up. Median follow up time of survivors was 6 years. Conclusions: This is a descriptive retrospective cohort study of adult patients in a real world setting who received CALGB 10403 induction and subsequently relapsed. Compared to other studies of relapsed ALL patients who were induced with traditional chemotherapy (Fielding et. al, 2007), survival 1 year after relapse was much higher (60% vs. 22%). As CALGB 10403 becomes an increasingly common induction regimen for AYA and adults with ALL, further outcomes study is required.[Table: see text]

Objective Clinical and laboratory guidelines recommend thyroglobulin antibodies (TgAbs) measurement with every thyroglobulin (Tg) measurement for the follow-up of differentiated thyroid cancer (DTC) patients. However, no evidence exists on the need for perpetual TgAbs testing in patients who are TgAb-negative at baseline. Our study was carried out to evaluate the prevalence, the dynamic changes, and the clinical significance of TgAbs that appeared de novo during the follow-up of DTC patients who were TgAb-negative at baseline. Methods The data of DTC patients with negative pre-ablation TgAbs were reviewed retrospectively. The main characteristics of patients with both transient and sustained de novo TgAbs appearance were analyzed. DTC patients with persistently negative TgAbs served as controls. Results Among 119 patients with pre-ablation negative TgAbs, 14 cases (11.7%) with de novo TgAbs appearance (10 and 4 patients with a transient and sustained de novo TgAbs appearance, respectively) were detected. No differences in disease-free survival were observed in patients with de novo TgAbs appearance compared to controls. The TgAbs peak value was higher in patients with sustained de novo appearance compared to patients with transient de novo. Two of 14 patients with de novo TgAbs developed structural disease with concurrently detectable Tg in both cases. Conclusions Transient de novo TgAbs appearance is not infrequent during DTC patients’ follow-up, and it has no apparent clinical impact. Sustained de novo TgAbs appearance is rare and may predict structural recurrences; however, similar disease-free survival was observed in patients with sustained de novo TgAbs and TgAb-negative DTC patients.

Abstract The American Joint Committee on Cancer (AJCC) 8th TNM staging system of differentiated thyroid cancer defines gross strap muscle invasion as T3b stage. However, the impact of strap muscle invasion on disease-specific survival (DSS) remains controversial. To elucidate the survival impact of strap muscle invasion of any degree in thyroid cancers, the Surveillance, Epidemiology, and End Results (SEER) database (1973–2018) was queried for thyroid cancer only patients on July 2019 (n = 19,914). The Cox proportional hazard analysis with multivariable adjustment revealed that strap muscle invasion was not a significant factor for DSS in tumors equal to or smaller than 40 mm (hazard ratio (HR) = 1.620 [confidence interval (CI) 0.917 – 2.860]; p = 0.097). The competing risk analysis with multivariable adjustment showed that strap muscle invasion did not significantly impact DSS regardless of tumor size or cause of death (cancer-caused death (Subdistribution HR (SDHR) = 1.567 [CI 0.984 – 2.495]; p = 0.059); deaths to other causes (SDHR = 1.155 [CI 0.842 – 1.585]; p = 0.370). A “modified” staging schema discarding strap muscle invasion as a T stage criterion showed better 10-year DSS distinction between T stages. The modified staging schema may better reflect cancer-caused death risk and may prevent potential overstaging.

PURPOSE Recently, we have shown that metastasis-free survival is a strong surrogate for overall survival (OS) in men with intermediate- and high-risk localized prostate cancer and can accelerate the evaluation of new (neo)adjuvant therapies. Event-free survival (EFS), an earlier prostate-specific antigen (PSA)–based composite end point, may further expedite trial completion. METHODS EFS was defined as the time from random assignment to the date of first evidence of disease recurrence, including biochemical failure, local or regional recurrence, distant metastasis, or death from any cause, or was censored at the date of last PSA assessment. Individual patient data from trials within the Intermediate Clinical Endpoints in Cancer of the Prostate–ICECaP–database with evaluable PSA and disease follow-up data were analyzed. We evaluated the surrogacy of EFS for OS using a 2-stage meta-analytic validation model by determining the correlation of EFS with OS (patient level) and the correlation of treatment effects (hazard ratios [HRs]) on both EFS and OS (trial level). A clinically relevant surrogacy was defined a priori as an R2 ≥ 0.7. RESULTS Data for 10,350 patients were analyzed from 15 radiation therapy–based trials enrolled from 1987 to 2011 with a median follow-up of 10 years. At the patient level, the correlation of EFS with OS was 0.43 (95% CI, 0.42 to 0.44) as measured by Kendall’s tau from a copula model. At the trial level, the R2 was 0.35 (95% CI, 0.01 to 0.60) from the weighted linear regression of log(HR)-OS on log(HR)-EFS. CONCLUSION EFS is a weak surrogate for OS and is not suitable for use as an intermediate clinical end point to substitute for OS to accelerate phase III (neo)adjuvant trials of prostate cancer therapies for primary radiation therapy–based trials.

Abstract Abstract 1772 Background: Hodgkin Lymphoma (HL) is the most curable type of Lymphoma with an overall survival at 5 years of 80%. ABVD can be considered as gold standard for first line treatment for all stages of HL. Dividing patients (pts.) in different prognostic groups has aimed to reduce chemo and radio toxicity in those patients with good prognosis. A negative PET-CT, either early during treatment of ABVD or after completion of it, has shown to be a powerful prognostic tool (Hutchings: Blood 2006; Gallamini: Haematologica 2006). Our cooperative group has an experience with 584 patients with HL in early or advanced stage treated with 3 or 6 cycles of ABVD plus involved field radiotherapy with a complete remission (CR) of 91% and an event free survival (EFS) and overall survival (OS) at 60 months of 79% and 95%.(S Pavlovsky, Clin Lymp My & Leuk, 2010). Aims: Test the efficacy of treatment to all stages of HL adjusted to PET-CT results after 3 cycles of ABVD. Evaluate the outcome of pts. who have a negative PET-CT after 3 cycles of ABVD and receive no further treatment. Intensify therapy only in pts. who have persistent hyper metabolic lesions in PET-CT after 3 cycles of ABVD. Method: Since October 2005, 198 newly diagnosed pts. with HL have been included in a prospective multicenter trial. Initially all patients received 3 cycles of ABVD. After the third cycle, pts. were evaluated with a PET-CT. Those pts. who achieved CR with a negative PET-CT, received no further treatment. Those with more than 50% of anatomic reduction of initial masses but persistent hyper metabolic lesions by PET-TC after 3 ABVD were considered in partial remission (PR) and completed 6 cycles of ABVD and radiotherapy (RT) on PET-CT positive areas. Those patients with less than PR after 3 cycles of ABVD received ESHAP and if CR, high doses of chemotherapy and an autologous stem cell transplant (ASCT). All patients were re-evaluated at the end of treatment. The median follow up is of 30 months (3-62). Results: One hundred and seventy three patients completed three cycles of ABVD followed by a PET-CT. The median age at diagnosis was 29 years. One hundred and thirty-six (79%) had localized stage (I-II) at diagnosis and 37 (21%) presented with advanced stage (III-IV). Of 155 pts. 77 (50%) pts had IPS 0–1, 66 (43%) had IPS 2–3 and 12 (8%) had IPS 4–5. Twenty six (17%) pts. had bulky disease at diagnosis. One hundred and thirty-seven (79%) pts. achieved CR with negative PET-CT after 3 cycles of ABVD. Thirty-six (21%) were PET-CT positive, of them 32 pts achieved PR and completed a total of 6 cycles of ABVD plus RT in hyper metabolic lesions. Twenty five achieved CR (72%), 5 persisted with PR and 2 died of progressive disease. Four pts showed progressive disease (PD) after 3 ABVD and received ESHAP and ASCT, 2 achieved and remained in CR, 1 is in PR and 1 died of progressive disease. Of 173 pts who completed treatment with ABVD × 3 cycles, ABVD × 6 cycles plus RT on PET-TC positive areas or ESHAP plus ASCT, 164 pts (95%) achieved CR. Of these 164 pts., 14 pts (8%) relapsed. The EFS and OS at 36 months is 83% and 97% respectively. Patients with early negative PET-TC have an event-free survival of 87% compared to 62% (P=0,001) for pts with early positive PET CT. The OS at 36 months was 100% versus 86% respectively (<0.001). Conclusion: Treating patients with ABVD, evaluating response after 3 cycles with PET-CT, and adapting further therapy, leads to a high rate of CR avoiding more aggressive chemotherapy and radiotherapy. Three courses of ABVD without RT are adequate in patients with early CR defined by negative PET-CT. In early positive PET-CT it is possible to intensify therapy improving the otherwise bad prognosis; more aggressive treatment might also be suitable. These results need to be confirmed by a larger group of patients and a longer follow-up. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: Peripheral T-Cell lymphomas (PTCLs) constitute approximately 10% of lymphoid malignancies and consist of several distinct entities based on pathologic and clinical characteristics. With the exception of a few subtypes (e.g., ALK-positive anaplastic large cell lymphoma (ALCL) and some primary cutaneous or leukemic forms of PTCL), a majority of PTCLs are aggressive as characterized by poor treatment response, rapid disease progression and poor overall survival. We have shown that landmark timepoints of event-free survival after diagnosis can stratify subsequent overall survival (OS) in diffuse large B-cell and follicular lymphoma. Here we evaluate this approach in newly diagnosed aggressive PTCLs treated with anthracyline-based or related chemotherapy. Methods. Newly diagnosed PTCL patients were prospectively enrolled in the University of Iowa/Mayo Clinic Lymphoma SPORE Molecular Epidemiology Resource (MER) from 2002-2012. Clinical data were abstracted from medical records using a standard protocol. For this analysis, we included patients receiving anthracycline-based or other multiagent chemotherapy for the following PTCL subtypes: ALK-negative ALCL (N=24); angioimmunoblastic T-cell lymphoma (AITL, N=34); PTCL, not otherwise specified (NOS; N=60); enteropathy-associated T-cell lymphoma (EATL, N=8); extranodal NK/T-cell lymphoma, nasal type (ENKTL, N=11); and hepatosplenic T-cell lymphoma (HSTCL, N=1). Patients were prospectively followed, and event-free survival (EFS) was defined as time from diagnosis to progression, re-treatment, or death due to any cause. Landmark EFS timepoints were assessed at 12 (EFS12) and 24 (EFS24) months after the date of diagnosis. Subsequent OS was defined as time from a specific endpoint (diagnosis, event or EFS landmark). Replication was performed in a population-based cohort of T-cell lymphomas diagnosed from 2000-2009 from the Swedish Lymphoma Registry. Results. 138 eligible patients were enrolled in the MER from 2002-2012, the median age at diagnosis was 58 years (range, 19-88), 66% were male, 73% had Stage III-IV disease, and 33% had IPI 0-1. At a median follow-up of 47 months (range 11-120), 87 patients (63%) had an event and 70 patients (51%) had died. From diagnosis, only 60 patients were event-free at 12 months (EFS12 45%). Patients who failed to achieve EFS12 had a poor subsequent OS from event (median OS = 6.8 months, 95% CI: 5.3-14.0, figure 1). In contrast, patients who achieved EFS12 had a favorable subsequent OS (median unreached, figure 2). Of the 427 eligible patients in the Swedish registry, the median age at diagnosis was 66 years (range, 18-88), 63% were male, 68% had Stage III-IV disease, and 25% had IPI 0-1. PTCL subtypes were: ALK-negative ALCL (N=89); AITL (N=80); PTCL, NOS (N=183); EATL (N=44); ENKTL (N=24); and HSTCL (N=7). At a median follow-up of 86 months (range 40-158), 333 patients (79%) had an event and 316 patients (74%) had died. From diagnosis, 183 patients were event-free at 12 months (EFS12 44%). Similar to the MER cohort, Swedish patients failing EFS12 had poor subsequent survival (median OS = 3.7 months, 95% CI: 2.9-5.3, figure 1). Swedish patients achieving EFS12 had a favorable subsequent OS (median OS = 89 months, figure 2). Similar results were obtained when conducting landmark analysis at 24 months after diagnosis (EFS24). Conclusion. Relapse and re-treatment events within the first 12 months of diagnosis are associated with very poor OS in PTCL treated with anthracyclines or related chemotherapy, while patients achieving EFS12 have encouraging subsequent OS. Stratifying patients into prognostically distinct subsets using EFS12 may help focus biologic and biomarker studies. EFS12 has potential as an early endpoint for studies of newly diagnosed PTCL. Further investigation of determinants related to post-EFS12 survival is needed. Disclosures Maurer: Kite Pharma: Research Funding. Cerhan:Kite Pharma: Research Funding.

672 Background: Investigation of high dose chemotherapy (HD-CT) supported by autologous hematopoietic stem cell transplantation compared with standard dose chemotherapy (SD-CT) as adjuvant treatment in patients with primary breast cancer and 10 or more axillary lymph nodes. Methods: Between November 1993 and September 2000 307 patients were randomized to receive the following cycles of Epirubicin (90 mg/m2), Cyclophosphamide (600 mg/m2) intervenously (every 21 days) either HD-CT of Cyclophosphamide (1500 mg/m2), Thiotepa (150 mg/m2) and Mitoxantrone (10 mg/m2) intervenously for 4 consecutive days followed by stem cell transplantation or standard dose chemotherapy SDCT in 3 cycles of Cyclophosphamide (500 mg/m2), Methotrexate (40 mg/m2) and Fluoruracil (600 mg/m2) intervenously on days 1 and 8 every 28 days. The primary end points were event-free survival and overall survival. Results: After a median follow-up of 6.1 years 166 events with respect to event-free survival (SD-CT: 91, HD-CT: 75) and 123 with respect to overall survival (SD-CT: 66 and HD-CT: 57) have been observed. The hazard ratio of HD-CT versus SD-CT is estimated as 0,80, p = 0,15. The hazard ratio for overall survival for high dose chemotherapy versus standard dose chemotherapy is estimated as 0,84, p = 0,33. Analysing the effect of treatment on event-free survival premenopausal patients, patients with tumor grade III and ER-positive patients had a better outcome with HD-CT with an interactive effect of 2.5 and 1.4. The significance was only shown in grade III patients in favour of HD-CT, (p = 0,049). The interactive effect of HD-CT with prognostic factors did not reach significance for overall survival. Conclusion: Even with a follow-up of 6.1 years there was only a trend in favour of high dose chemotherapy with respect to overall survival but without a statistical significance. A proper meta-analysis needs to be undertaken for an evaluation of subgroups of patients which might benefit from this treatment approach. No significant financial relationships to disclose.
