Radiation-associated versus sporadic osteosarcoma: A single-institution experience.

11018 Background: Osteosarcoma (osarc) can be a rare complication from radiation (rt) therapy. Radiation-associated osarc (RAO) is reported to have a worse prognosis than non rt-associated osarc with limited objective data comparing the two. We conducted a retrospective study comparing demographics, therapy and outcomes of sporadic osarc (SO) to RAO. This study was confined to adults. Methods: We identified patients (pts) > age 18 years (yr) with osarc treated at our institution between 1990 and 2016 using an institutional database. We categorized tumors as SO or RAO based on history of prior rt within field of osarc. We extracted data on demographics, treatment, and primary malignancy characteristics. Results: We identified 159 pts with osarc, 28 were RAO tumors. Results are in Table 1. Median follow-up was 2.8 yr (0.1-19.6 yr). For RAO, median time from rt to diagnosis was 11.5 yr (1.5-28 yr) with a median cumulative dose of 60 Gy (44-75.8 Gy). Median progression free survival (PFS) and overall survival (OS) were not significantly different in pts presenting with metastatic osarc; PFS 10.3 mo vs 4.8 mo (p=0.45) and OS 15.6 mo vs 6.1 mo (p=0.96) in SO vs RAO pts, respectively. For pts with localized osarc, median relapse-free survival (RFS) and OS were significantly different, not reached vs 12.2 mo (p<0.001) and not reached vs 27.6 mo (p=0.001) in SO vs RAO, respectively. Conclusions: In our series, there was a significant difference in age, size and location of RAO vs non rt-associated osarc. Overall, all osarc pts with metastatic disease at diagnosis fared poorly. Pts presenting with localized RAO had worse outcomes than patients with localized SO. This was not associated with a detectable difference in therapy rendered or treatment effect in resection specimens. [Table: see text]

Abstract Background An upgraded understanding of factors (sex/estrogen) associated with survival benefit in advanced colorectal carcinoma (CRC) could improve personalised management and provide innovative insights into anti-tumour mechanisms. The aim of this study was to assess the efficacy and safety of cetuximab (CET) versus bevacizumab (BEV) following prior 12 cycles of fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI) plus BEV in postmenopausal women with advanced KRAS and BRAF wild-type (wt) CRC. Methods Prospectively maintained databases were reviewed from 2013 to 2017 to assess postmenopausal women with advanced KRAS and BRAF wt CRC who received up to 12 cycles of FOLFOXIRI plus BEV inductive treatment, followed by CET or BEV maintenance treatment. The primary endpoints were overall survival (OS), progression-free survival (PFS), response rate. The secondary endpoint was the rate of adverse events (AEs). Results At a median follow-up of 27.0 months (IQR 25.1–29.2), significant difference was detected in median OS (17.7 months [95% confidence interval [CI], 16.2–18.6] for CET vs. 11.7 months [95% CI, 10.4–12.8] for BEV; hazard ratio [HR], 0.63; 95% CI, 0.44–0.89; p=0.007); Median PFS was 10.7 months (95% CI, 9.8–11.3) for CET vs. 8.4 months (95% CI, 7.2–9.6) for BEV (HR, 0.67; 95% CI 0.47–0.94; p=0.02). Dose reduction due to intolerable AEs occurred in 29 cases (24 [24.0%] for CET vs. 5 [4.8%] for BEV; p< 0.001). Conclusions CET tends to be superior survival benefit when compared with BEV, with tolerated AEs.

Abstract Context: The natural history of malignant pheochromocytoma or paragangliomas (MPP) remain unknown. Objective: The primary aim of this study was to define progression-free survival at 1 year in therapy-naive patients with MPP. Secondary objectives were to characterize MPP and to look for prognostic parameters for progression at 1 year. Design and Setting: The files of MPP followed up between January 2001 and January 2011 in two French Endocrine Networks were retrospectively reviewed. Therapy-naive patients were enrolled. Main Outcome Measures: The main outcome was progression-free survival at 1 year in therapy-naive MPP patients according to Response Evaluation Criteria In Solid Tumors 1.1 criteria. Results: Ninety files (46 men, 44 women, mean age of 47.5 ± 15 years) were reviewed on site by one investigator. MPP characteristics were as follows: presence of an adrenal primary, a mitotic count exceeding 5 per high power field, hypertension, inherited disease, and presence of bone metastases in 50%, 22%, 60%, 49%, and 56% patients, respectively. Fifty-seven of the 90 patients with MPP (63%) were classified as therapy-naive. The median follow-up of these 57 patients was 2.4 years (range, 0.4–5.7). At 1 year, progression-free survival was 46% (CI 95: 33–59). Twenty-six of 30 (87%) patients with progression at 1 year had exhibited progressive disease at the first imaging workup performed after a median of 5.7 months. No prognostic parameter was identified. Conclusions: Half of the therapy-naive patients with MPP achieved stable disease at 1 year. In symptom-free patients with MPP, a wait-and-see antitumor policy seems appropriate as first line. Modality for a prospective follow-up is proposed.

Abstract BACKGROUND Temozolomide (TMZ) is the cornerstone for glioblastoma (GBM) treatment. A significant proportion of patients develops hematologic toxicities with limited investigations on outcomes and risk factors for their development. METHODS Our study combines data from the two largest group trials, RTOG 0525 and RTOG 0825, to analyze serious hematologic adverse events (HAE) associated with TMZ therapy for GBM. We analyzed frequency and outcomes of HAE during chemoradiation. RESULTS 1154 patients were evaluated with a median age of 57 years. Over 79% of patients developed HAE during the entire course of GBM treatment. During chemoradiation the most common HAE during chemoradiation was lymphopenia (41.5%), followed by thrombocytopenia (39.0%), and anemia (35.3%). Of these, 34.1% were severe (Grade 3 or 4) and 65.9% were mild (grade 1 or 2). During maintenance the most common HAE was leukopenia (50.7%), followed by neutropenia (50.4%), and lymphopenia (45.3%). MGMT methylation was not associated with HAEs. A history of HAEs during chemoradiation was a protective factor for developing HAEs during maintenance. MGMT methylated and age younger than 50 were protective factors for mortality. Patients that presented HAEs anytime during treatment had a longer overall survival and progression free survival. There was no significant difference in survival between mild or severe HAEs. CONCLUSION HAE are common during chemoradiation with TMZ for GBM, but are more commonly grade 1 or 2 per CTCAE. HAE during GBM treatment is associated with decreased progression free survival and overall survival.

Abstract Several factors influencing disease progression and survival have been identified in multiple myeloma (MM). We analysed a series of 49 consecutive patients with MM that underwent autologous haematopoietic progenitor cell transplant (HPCT) in one center regarding the following variables: use of G-CSF for haematopoietic recovery post-transplant; recovery of normal IgM levels at day +100 post-transplant; levels of lymphocytes namely of the CD4+ and CD8+ subsets also at day +100. Before 2006, all patients had G-CSF starting 24 hours after the cell infusion until neutrophil > 500×10^9/L in two consecutive days; in the years 2006–2008, no G-CSF was given to transplanted patients. A historical comparison was done and at the time of this study no significant difference in progression free survival (Kaplan-Meyer analysis), was detected between the two groups, possibly due to the shorter follow-up of the “no G-CSF” (n=19) group; nevertheless median progression free survival (PFS) in the “G-CSF” group was 12 months while median PFS was not attained in the “no G-CSF” group (median follow-up = 7 months). Post transplant IgM levels were also determined in 39 patients. Eighteen patients recovered normal IgM levels at day +100 (46.8 %) and 21 (53.8 %) did not. Comparison of Kaplan-Meyer curves for the two groups did not show any statistically significant difference but there is a sharp difference between median PFS of the “low IgM” (10 months) and the “normal IgM” (27 months) groups. CD4/CD8 ratio was determined in 18 patients at day +100. The ratio varied between 0 and 0.63 (median – 0.305). No correlation was found between post-transplant IgM recovery and CD4/CD8 ratio. In conclusion, in our series of MM patients treated with autologous HPCT we could not find a definite relationship between immunologic recovery and response to treatment although there is a trend to a better outlook of the patients which recover normal IgM levels. It is also uncertain whether use of G-CSF in the post-transplant period would have any effect on disease behaviour.

Abstract Background: The addition of ixazomib to the doublet lenalidomide and dexamethasone (RD) in relapsed and refractory multiple myeloma (RRMM) has shown significant benefit in progression free survival (PFS) in the TOURMALINE-MM1 study. Several real-world data including our previous analysis confirmed that the combination IRD is feasible and with fair outcomes even outside the clinical trial. Here we report an updated analysis which is aimed at overall survival (OS) and the PFS2 interval which is defined as the time from the date of treatment initiation to the date of first documentation of progressive disease after initiation of further anti-myeloma treatment or death from any cause. Methods: We analyzed a cohort of 344 patients with RRMM, 127 being treated by IRD and 217 by RD combination. The group characteristics and study design are described elsewhere. 1 The median follow-up of the whole cohort was 28.5 months. The primary endpoint was OS, OS in patients with relapse 1-3, progression free survival (PFS), and PFS2. Secondary endpoints were response rates and toxicity profile. For statistical analysis we used Fisher's exact test or Mann-Whitney U test. Survival measures were assessed using the Kaplan-Meier methodology, and statistical significance was assessed using the log-rank test at a significance level of α = 0.05 (all tests two-sided). Results: The outcomes of OS in the whole cohort were already published before, with significantly longer median OS in the IRD vs RD cohort (mOS 36.6 months vs 26.0 months, p = 0.008).1 In the follow-up analysis, the medians were slightly improved, maintaining a significant difference (mOS 40.9 vs 27.1 months, p = 0.001). In patients treated within relapse 1-3, the results outcomes were even more pronounced (mOS 51.7 vs 27.8 months, p ˂ 0.001). The median PFS was also better in the IRD cohort (mPFS 17.5 vs 12.5 months, p = 0.013) but the results did not substantially differ from our previous analysis. The median PFS2 in the IRD vs RD cohort was significantly longer in the IRD cohort (mPFS2 29.8 vs 21.6 months, p = 0.016). The subsequent therapy included mostly pomalidomide (27.5% vs 30.8%), bortezomib (28.8% vs 28.2%) or thalidomide (10.0% vs 16.2%). Monoclonal antibodies (daratumumab, isatuximab) were more frequently used after IRD combination (21.3% vs 4.3%). The response rates in the IRD vs RD cohort were similar as in our primary analysis: overall response rate (ORR) 73.0% vs 66.8%, with significant difference in very good partial response and better (VGPR+) 38.1% vs 26.3%. The toxicity profile did not reveal any additional safety concerns. Majority of grade 3+ toxicities included hematological toxicity (anemia, neutropenia, thrombocytopenia) and infections, with similar distribution in the cohorts. Conclusion: The treatment of RRMM using the full oral IRD regimen in routine clinical practice is easy, safe and with significantly improved outcomes in comparison to RD doublet. Our follow-up analysis confirmed the impact on OS in patients in the whole cohort including relapse 1-3. The median PFS2 was also longer in the IRD cohort, possibly affected by more frequent use of monoclonal antibodies in the next treatment.

Abstract Median age at diagnosis of chronic lymphocytic leukemia is 72 years. However, only few patients over 80 years of age are included in clinical trials, even in those devoted to unfit patients. In order to evaluate both efficiency and safety of venetoclax in this category of patients, we conducted a multicentric retrospective study and collected data from 77 CLL patients from 19 FILO centers who started venetoclax after 80 years of age. Median age at venetoclax initiation was 86 years old (81-97). 63% of patients had a history of heart disease, 62% had renal failure (moderate 59% and severe 3%) and 29% had a history of severe infections. Despite their comorbidities and a CIRS greater than 6 in 70% of cases, their autonomy was preserved with a median performans status of 1 (0-4). In this comorbid geriatric population, pretherapeutic geriatric assessment was only performed in a single patient. The median number of prior therapies was 2 (0-6) with an exposure to a BCR inhibitor in 56% of cases. 11q and 17p deletion were found in 39% and 30% of cases respectively, 39% of patients had a complex karyotype and 30% harbored a TP53 mutation. However, in this real life population, these prognostic factors were only performed in half of patients. IGHV mutational status was only available in 11 patients, and 83% of them had unmutated IGHV. At the time of venetoclax initiation, the tumor lysis syndrome (TLS) risk was moderate in 57% of cases and high in 8% of cases. Venetoclax was administered as a single agent (42%) or in association with rituximab (58%). In total, half of the patients were hospitalized at each dose ramp-up, and only 3 patients were treated on outpatient basis. 82% of the cohort was able to reach the daily dose of 400mg. Half of the patients were included in a phone call monitoring program with oncology nurses to pre-emptively manage side effects and foster therapy adherence. The safety study reported 14% of TLS, with 2 discontinuations of treatment within the first month: one of which led to dialysis and the other to death. As in the previously published studies, 25% of patients had infectious complications, and grade 3 haematological and digestive toxicities were reported in 42% and 22% of cases, respectively. The reduction of the daily dose of venetoclax was necessary for 33%. Permanent discontinuation of venetoclax occurred in 40% of subjects, including 29% of early withdrawal (within the first 3 months). Main reasons for discontinuation were intolerance (21%), CLL progression (21%), death (21%) and scheduled treatment discontinuation (10%). The overall response rate was 86%, consisting of 49% of complete response (unconfirmed by bone marrow biopsy) and 37% of partial response. With a median follow-up of 21months, estimated progression free survival and overall survival were 29 and 38 months respectively. Prior exposure to a BCR inhibitor had no impact on progression free survival. To conclude, venetoclax has a manageable safety profile in elderly patients with comorbidities and can induce prolonged responses. Finally, if additional follow-up by oncology nurses seems to be more and more implemented, the pre-therapeutic onco-geriatric evaluation remains underexploited in this population.

3512 Background: Targeting both PD-L1 and CTLA-4 may be synergistic immunotherapy approaches. CO.26 evaluated if dual inhibition leads to improved pt survival vs BSC alone in rmCRC. Methods: rmCRC pts were randomized 2:1 to D+T vs BSC. Treatment consisted of D (1500 mg) D1 q 28 days and T (75 mg) D1 for first 4 cycles, and supportive measures. Primary endpoint was overall survival (OS). Two-sided p < 0.10 was considered statistically significant. Cell-free (cf)DNA sequencing for MSI and TMB used GuardantOMNI panel and baseline plasma. Results: From 08/2016-06/2017, 180 pts were enrolled. Pt characteristics were balanced between arms. At median follow-up of 15.2 months (mos), median OS was 6.6 mos for D+T and 4.1 mos for BSC (p = 0.07; Hazard ratio (HR): 0.72, 90% confidence interval (CI): 0.54 – 0.97). Progression free survival (PFS) was 1.8 mos vs 1.9 mos, respectively (HR 1.01, 90% CI 0.76 – 1.34). Disease control rate (DCR) was 22.6% for D+T and 6.6% for BSC (p = 0.006). cfDNA analysis was successful in 168/169 pts (99.4%). Two pts were MSI-high. In 166 MSS pts, OS HR was 0.66 (p=0.024; 90% CI 0.49-0.89). Excluding the MSI-H cases (TMB of 74.7 and 247.1 mts/Mb), mean TMB was 20.4 ± 16.3 mts/Mb (range: 0.96 – 114.0). In MSS pts, a pre-specified cutpoint of 20 mts/Mb stratified pts into high and low TMB groups but was not predictive for OS , PFS, or DCR (interaction p-values > 0.7). Using a minimum p-value approach, pts with TMB >28 mts/Mb (21% of MSS pts) had the greatest OS benefit (HR 0.34, 90% CI 0.18-0.63) for D+T (interaction p = 0.07). High TMB was associated with a trend in worse prognosis for OS in the BSC arm using both 20 mts/Mb (HR 1.26, 90% CI 0.76-2.12) and 28 mts/Mb (HR 2.59 90% CI 1.46-4.62) cutpoints. Conclusions: D+T significantly prolonged OS in pts with rmCRC. High TMB may select a group of MSS pts who benefit from D+T. Plasma TMB appeared prognostic in the BSC arm. This is the first study showing combined PD-L1 and CTLA-4 inhibition prolongs survival in pts with MSS rmCRC. Updated results based on deaths in more than 90% of pts will be presented.

Abstract Context.—Sarcomatous transformation is a rare complication of Paget disease of bone. Prognosis in patients with other types of sarcomas arising in bone has improved in the last several decades because of therapeutic advances. However, because of the rarity of Paget sarcoma, outcome studies in these patients are limited. Objective.—To determine whether prognosis for Paget sarcoma has improved. Design.—Seventy cases of sarcomas arising in the setting of Paget disease were collected, and the histologic and clinical findings were reviewed. Clinical follow-up was obtained in 67 cases. Results.—Sarcoma arising in Paget disease tended to arise in older men (46 men, 24 women; age range, 31–88 years; mean age, 66 years) and predominated in the axial skeleton (n = 37), especially in the pelvis. Thirty-three patients had a clinical history of Paget disease ranging in duration from 16 months to 30 years (mean, 15 years). No significant difference in incidence between monostotic (n = 33) and polyostotic (n = 36) disease was noted. Most tumors were osteosarcomas (88%). All tumors were high grade. Follow-up information was obtained in 67 of 70 cases (range of follow-up, 1–252 months). Survival ranged from 1 month to 20 years, with a 5-year survival rate of 10%. Conclusions.—Prognosis remains poor in patients with Paget sarcoma. There is no significant correlation between the number of bones involved with Paget disease or the duration of disease and development of Paget sarcoma. Poor prognosis in Paget sarcoma is unrelated to site or stage at presentation.

e16569 Background: Inflammatory markers have been studied as prognostic markers in patients with mRCC treated with CPIs. Recently, eosinophilia has been found to be associated with improved survival of patients with melanoma treated with CPIs. We reported baseline NER in patients with mRCC treated with CPIs and its association with clinical outcomes. Methods: We conducted a retrospective analysis of patients with mRCC treated with CPIs at Winship Cancer Institute from 2015-2018. Clinical outcomes were measured as overall survival (OS), progression-free survival (PFS), and clinical benefit (CB). OS and PFS were calculated from CPI-initiation to date of death and radiographic or clinical progression, respectively. Patients with baseline NER were categorized into high or low; high defined as NER > 49.2 and low defined as NER < 49.2. Univariate (UVA) and multivariate (MVA) analyses were carried out for OS and PFS using Cox proportional hazard model. Results: A total of 184 patients were studied with a median follow up of 25.4 months. Median age was 63 years old with 72% male and 20% black. About 25% were in high NER group. The high NER patients had significantly shorter OS in both UVA (HR: 0.58, p-value=0.017) and MVA (HR: 0.62, p-value=0.046) (Table). There was no significant difference between groups for PFS. Clinical benefit was seen in 47.3% of patients with low baseline NER and 40% with high NER. Conclusions: High baseline NER was associated with worse OS in patients with mRCC treated with CPIs. Larger, prospective studies are warranted to validate this hypothesis generating data.[Table: see text]

Background: Cholangiocarcinoma (CCA) is a rare malignant tumor of the bile duct epithelium. At first diagnosis, only a minority of patients are eligible for surgery, which is regarded as the only curative treatment. This study examines the role of radiation therapy (RT) and chemoradiotherapy (CRT) in the definitive and adjuvant treatment situation. Methods: The monocentric, retrospective analysis included 39 patients with CCA undergoing 53 RT courses. Data were collected from January 2005 to September 2018. There were 11 cases of CRT, 6 of which were definitive. Surgery was either palliative (n = 6) or radical (n = 15). Results: After RT, the median overall survival (OS) was 10.4 months (m), median progression-free survival was 5.6 m, and median duration of local control (DOLC) was 8.9 m. There was a significant difference in survival between patients with and without locoregional lymph node metastasis (OS: 4.3 vs. 15.4 m, p = 0.031). After treatment of a primary tumor, DOLC was about twice as long as in the recurrent situation (10.4 vs. 5.4 m, p = 0.032). Conservative therapy significantly elevated the risk of local recurrence compared to radical surgery in univariate and multivariate analyses. Side effects were mostly classified as mild to moderate. Termination of RT and increased alanine aminotransferase were significantly less frequent after stereotactic body radiation therapy and hypofractionation. Conclusion: RT can achieve local control in patients with CCA. Toxicities of RT are manageable but require close clinical and laboratory follow-up.
