109 Background: Trials in human papilloma virus associated oropharyngeal squamous cell carcinoma (HPVOPSCC), substituting cetuximab (CETUX) for cisplatin (CIS) with radiotherapy (RT), resulted in decreased efficacy without improved toxicity or symptom burden. We reported that high intratumoral immune cell (ITIC) CD103 expression (> 30%), a marker of tissue-resident memory T cells, is associated with better prognosis in unselected patients with HPVOPSCC treated with CIS/RT. In this study our aim was to determine whether low risk HPVOPSCC patients treated with CETUX/RT with high CD103 have a superior prognosis. Methods: TROG 12.01 and De-ESCALaTE are randomised multicentre trials that compared 70Gy RT/CETUX with 70Gy RT/CIS (weekly in TROG 12.01, 3-weekly in De-ESCALaTE) in patients with HPVOPSCC, low risk by Ang criteria: AJCC 7th Stage III (excluding T1-2N1) or stage IV (excluding N2b-c if smoking history > 10 pack years and/or distant metastases). In TROG 12.01 T4 and/or N3 patients were also excluded. Eligible patients required tumor samples available for immune cell quantification on immunohistochemistry. Data from the two trials were pooled, with analyses performed in eligible randomised patients who commenced treatment. The primary endpoint was failure-free survival (FFS) in patients receiving CETUX/ RT comparing CD103 ITIC > 30% (high) vs. < 30% (low). High/low CD103 were compared using Cox model adjusting for age, stage and trial. Results: Samples for CD103 testing were available in 159/182 patients on TROG 12.01 and 145/334 on De-ESCALaTE. ITIC CD103 expression was high in 26% of patients. The median follow-up was 3.2 years. The 3 -year failure-free survival rates in patients treated with CETUX/RT were 92% (95% CI: 78-97%) in high CD103 and 74% (95% CI: 64-82%) in low CD103, adjusted HR 0.25 (95% CI: 0.14-0.44); p < 0.001. The 3 -year overall survival (OS) in patients treated with CETUX/RT were 100% in high CD103 and 86% (95% CI: 76-92%) in low CD103, p < 0.001. Superior FFS in the high CD103 group was independent of stage. In patients treated with CIS/RT there was no significant difference in FFS (3-year 86% in high CD103 and 90% in low CD103; p = 0.55) or in OS (3-year 100% in high CD103 and 95% in low CD103; p = 0.14). The increase in failures in the low CD103 patients treated with CETUX/RT was evenly split between distant and locoregional failures. Conclusions: ITIC CD103 separates CETUX/RT treated low risk HPVOPSCC into excellent and poor prognosis subgroups. In a low risk population CIS/RT achieves excellent outcomes in both high and low ITIC CD103 groups. The high ITIC CD103 population is a rational target for future de-intensification trials.

Little is known about breast cancer in Vietnamese women. Previous studies have reported the frequencies of prognostic factors of breast cancer in this population. The aim of this study was to examine the prognostic factors associated with the survival rates of patients with breast cancer treated at the National Cancer Hospital, Hanoi, Vietnam. We recruited 248 women with operable breast cancer treated with surgery and adjuvant therapy. Tumor tissue samples were stained by many immunohistochemical approaches and analyzed for estrogen receptor, progesterone receptor, and HER2 gene amplification status. A Cox model was used to determine the relationship between survival and the prognostic factors. The disease-free survival rate, overall survival rate, and cancer-specific survival rate were 75.8%, 80.6%, and 86.4%, respectively, at 5 years and 62.3%, 68.1%, and 78.9%, respectively, at 10 years. The lung was the most common metastatic site. Women with factors associated with a poor prognosis (eg, advanced clinical stage, high tumor grade, progesterone receptor [PR] negativity, HER2 amplification) had significantly lower survival rates. Patients with PR-negative breast cancer had significantly worse survival rates compared to those who were PR positive, according to multivariate analysis (hazard ratio = 1.77, 95% confidence interval: 1.01-3.11, P = .045); however, there was only a statistically significant difference in postmenopausal patients. The PR was a prognostic factor in postmenopausal women with breast cancer, but not in premenopausal women.

6012 Background: The excellent prognosis of patients with low risk HPV associated oropharyngeal squamous cell carcinoma has led to concerns about overtreatment and excessive toxicity with radiotherapy and cisplatin, leading to interest in de-intensification trials. We investigated whether cetuximab, an EGFR targeting antibody, when combined with radiotherapy would result in a decrease in symptom burden and toxicity with similar efficacy when compared to weekly cisplatin. Methods: TROG 12.01, a randomised, multicentre trial involving 15 sites in Australia and New Zealand enrolled patients with HPV associated oropharyngeal squamous cell carcinoma, AJCC 7th edition Stage III (excluding T1-2N1) or stage IV (excluding T4 and/or N3 and/or N2b-c if smoking history >10 pack years and/or distant metastases). Patients were randomised (1:1) to receive radiotherapy (70Gy in 35 fractions) with either weekly cisplatin, 7 doses of 40mg/m2 or cetuximab, loading dose of 400mg/m2 followed by 7 weekly doses of 250 mg/m2. The primary outcome was symptom severity assessed by the MD Anderson Symptom Inventory Head and Neck Symptom Severity Scale from baseline to 13 weeks post completion of radiotherapy using the area under the time-severity curve (AUC). Sample size was 170 evaluable patients to provide at least 90% power to detect an effect size of 0.5, using a 2-sided test at 0.05 level of significance. Trial was registered on ClinicalTrials.gov: NCT01855451. Results: Between 17th June 2013 and 7th June 2018, 189 patients were enrolled and 182 were evaluable, with 92 on cisplatin arm and 90 on cetuximab included in the main analysis. The median follow-up was 4.1 years (0.4 - 5.3). Analyses were performed in all eligible randomised patients that commenced treatment (modified intention-to-treat population). There was no difference in the primary endpoint of symptom severity; difference in AUC cetuximab – cisplatin was 0.05 (95%CI: -0.19, 0.30), p= 0.66. The T-score (mean number of > grade 3 acute adverse events) was 4.35 (SD 2.48) in the cisplatin arm and 3.82 (SD 1.8) in the cetuximab arm, p= 0.108. The 3 -year failure-free survival rates were 93% (95% CI: 86-97%) in the cisplatin arm and 80% (95% CI: 70-87%) in the cetuximab arm (hazard ratio = 3.0 (95% CI: 1.2-7.7); p=0.015. The increase in failures in the cetuximab arm was evenly split between distant and locoregional failures. Conclusions: For patients with low risk HPV associated oropharyngeal cancer, radiotherapy and cetuximab had inferior failure-free survival without improvement in symptom burden or toxicity compared to radiotherapy and weekly cisplatin. Radiotherapy and cisplatin remains the standard of care. Clinical trial information: NCT01855451.

Abstract Background The effects of interferon-based therapies for hepatitis C virus (HCV) upon the risk of diabetes are controversial. The effects of newer, directly acting antiviral agents (DAA) upon this risk are unknown. We sought to determine the effects of HCV treatment upon the risk and incidence of diabetes. Methods Using the Electronically Retrieved Cohort of HCV Infected Veterans (ERCHIVES) database for persons with chronic HCV infection (n = 242 680), we identified those treated with a pegylated interferon and ribavirin regimen (PEG/RBV, n = 4764) or a DAA-containing regimen (n = 21 279), after excluding those with diabetes at baseline, those with a human immunodeficiency virus or hepatitis B virus coinfection, and those treated with both PEG/RBV and DAA regimens. Age-, race-, sex-, and propensity score–matched controls (1:1) were also identified. Results Diabetes incidence rates per 1000 person-years were 20.6 (95% confidence interval [CI] 19.6–21.6) among untreated persons, 19.8 (95% CI 18.3–21.4) among those treated with PEG/RBV, and 9.89 (95% CI 8.7–11.1) among DAA-treated persons (P < .001). Among the treated, rates were 13.3 (95% CI 12.2–14.5) for those with a sustained virologic response (SVR) and 19.2 (95% CI 17.4–21.1) for those without an SVR (P < .0001). A larger reduction was observed in persons with more advanced fibrosis/cirrhosis (absolute difference 2.9 for fibrosis severity score [FIB-4] < 1.25; 5.7 for FIB-4 1.26–3.25; 9.8 for FIB-4 >3.25). DAA treatment (hazard ratio [HR] 0.53, 95% CI .46–.63) and SVR (HR 0.81, 95% CI .70–.93) were associated with a significantly reduced risk of diabetes. DAA-treated persons had longer diabetes-free survival rates, compared to untreated and PEG/RBV-treated persons. There was no significant difference in diabetes-free survival rates between untreated and PEG/RBV-treated persons. The results were similar in inverse probability of treatment and censoring weight models. Conclusions DAA therapy significantly reduces the incidence and risk of subsequent diabetes. Treatment benefits are more pronounced in persons with more advanced liver fibrosis.

Abstract Background Ischemic heart disease (IHD) is a major underlying etiology in patients with heart failure (HF). Although the impact of IHD on HF is evolving, there is a lack of understanding of how IHD affects long-term clinical outcomes and uncertainty about the role of IHD in determining the risk of clinical outcomes by gender. Purpose This study aims to evaluate the gender difference in impact of IHD on long-term clinical outcomes in patients with heart failure reduced ejection fraction (HFrEF). Methods Study data were obtained from the nationwide registry which is a prospective multicenter cohort and included patients who were hospitalized for HF composed of 3,200 patients. A total of 1,638 patients with HFrEF were classified into gender (women 704 and men 934). The primary outcome was all-cause death during follow-up and the composite clinical events of all-cause death and HF readmission during follow-up were also obtained. HF readmission was defined as re-hospitalization because of HF exacerbation. Results 133 women (18.9%) were died and 168 men (18.0%) were died during follow-up (median 489 days; inter-quartile range, 162–947 days). As underlying cause of HF, IHD did not show significant difference between genders. Women with HFrEF combined with IHD had significantly lower cumulative survival rate than women without IHD at long-term follow-up (74.8% vs. 84.9%, Log Rank p=0.001, Figure 1). However, men with HFrEF combined with IHD had no significant difference in survival rate compared with men without IHD (79.3% vs. 83.8%, Log Rank p=0.067). After adjustment for confounding factors, Cox regression analysis showed that IHD had a 1.43-fold increased risk for all-cause mortality independently only in women. (odds ratio 1.43, 95% confidence interval 1.058–1.929, p=0.020). On the contrary to the death-free survival rates, there were significant differences in composite clinical events-free survival rates between patients with HFrEF combined with IHD and HFrEF without IHD in both genders. Figure 1 Conclusions IHD as predisposing cause of HF was an important risk factor for long-term mortality in women with HFrEF. Clinician need to aware of gender-based characteristics in patients with HF and should manage and monitor them appropriately and gender-specifically. Women with HF caused by IHD also should be treated more meticulously to avoid a poor prognosis. Acknowledgement/Funding None

PURPOSE This randomized, prospective trial compares outcomes for patients with advanced Hodgkin's disease treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)/doxorubicin, bleomycin, and vinblastine (ABV) hybrid regimen or alternating MOPP/doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). METHODS Three hundred one patients with advanced Hodgkin's disease were randomized to receive MOPP/ ABV hybrid regimen or alternating MOPP/ABVD after stratification for prior treatment, B symptoms, and treatment center. Eligible patients were either previously untreated and found to have stage IIIB, IVA, or IVB disease or previously treated with wide-field irradiation. Responding patients received a minimum of eight cycles of chemotherapy. Those with residual disease in a localized region received irradiation between the sixth and seventh cycle of treatment. RESULTS Response rates to the two regimens were similar. Five-year overall survival rates were 81% and 83% for MOPP/ABV hybrid and alternating MOPP/ ABVD, respectively (P = .74; 95% confidence interval [CI] for the difference, -11% to 7%). Five-year failure-free survivals were 71% and 67% for MOPP/ABV hybrid and alternating MOPP/ABVD, respectively (P = .87; 95% CI for the difference, -9% to 17%). Significantly more episodes of febrile neutropenia and stomatitis were observed with the MOPP/ABV hybrid regimen; there was no significant difference in fatal toxicity. Patients with predefined, high-quality partial responses (PR-1s) had results similar to those with complete responses (CRs). Planned subset analysis showed no significant difference in outcome between the two arms of the trial for patients with newly diagnosed disease (5-year failure-free survival rates were 70% for MOPP/ABV hybrid and 59% for alternating MOPP/ABVD; P = .180), but superiority of alternating MOPP/ABVD for patients with prior irradiation (5-year failure-free survival 94% v 73%; P = .017). CONCLUSION MOPP/ABV hybrid and alternating MOPP/ABVD regimens are equally effective for patients with advanced Hodgkin's disease.

Abstract Background Intrahepatic cholangiocarcinoma is an aggressive liver carcinoma with increasing incidence and mortality. A good auxiliary prognostic prediction tool is desperately needed for the development of treatment strategies. The purpose of this study was to explore the prognostic value of the radiomics nomogram based on enhanced CT in intrahepatic cholangiocarcinoma. Methods In this retrospective study, 101 patients with pathological confirmation of intrahepatic cholangiocarcinoma were recruited. A radiomics nomogram was developed by radiomics score and independent clinical risk factors selecting from multivariate Cox regression. All patients were stratified as high risk and low risk by a nomogram. Model performance and clinical usefulness were assessed by calibration curve, ROC curve, and survival curve. Results A total of 101patients (mean age, 58.2 years old; range 36–79 years old) were included in the study. The 1-year, 3-year, and 5-year overall survival rates were 49.5%, 26.6%, and 14.4%, respectively, with a median survival time of 12.2 months in the whole set. The least absolute shrinkage and selection operator (LASSO) method selected 3 features. Multivariate Cox analysis found three independent prognostic factors. The radiomics nomogram showed a significant prognosis value with overall survival. There was a significant difference in the 1-year and 3-year survival rates of stratified high-risk and low-risk patients in the whole set (30.4% vs. 56.4% and 13.0% vs. 30.6%, respectively, p = 0.018). Conclusions This radiomics nomogram has potential application value in the preoperative prognostic prediction of intrahepatic cholangiocarcinoma and may facilitate in clinical decision-making.

Abstract Purpose: The GHSG HD9 trial had established BEACOPP escalated (BE) as new standard of care for advanced-stage HL patients by showing significant superiority in terms of failure-free survival (FFTF) and overall survival (OS) over COPP/ABVD and BEACOPP baseline (BB) (each 8 cycles). The successor study, HD12, evaluated a possible reduction in toxicity by comparing 8 cycles of BE with 4 cycles BE followed by 4 cycles BB. The second question in this trial related to the need of additional radiotherapy (RT) to initial bulk and residual disease. Patients and methods: HL patients in stage IIB with large mediastinal mass and/or E-lesions or stage III/IV were randomised according to a 2×2-factorial design between: 8BE + RT, 8BE no RT, 4BE+4BB + RT, 4BE+4BB no RT. Reviewing CT-images before and after chemotherapy treatment, fields for RT were centrally planned by a multidisciplinary diagnostic panel blinded for the randomisation arm. Primary endpoint of the trial was FFTF. Between 9/1999 and 1/2003, a total of 1,670 patients aged 16–65 were randomized. For this final analysis at a median follow up of 78 months, 99 patients were excluded (42 HL not confirmed, 20 revision of stage, 20 no study treatment or documentation, 17 others) resulting in 1,571 eligible patients. Results: Patient characteristics in the 4 groups were comparable with 49% of patients in stage III, 35% in stage IV, 68% reporting B-symptoms and 28% having a large mediastinal tumor. An IPS of 3 or greater was reported for 38% of patients, predominant histology was nodular sclerosis with 57% of cases. Treatment-related toxicity of WHO grade III/IV was observed in 97% of patients. Most prominent differences between pooled chemotherapy arms were anemia (65% 8BE vs 51% 4BE+4BB) and thrombopenia (65% vs 51%). Treatment outcome: complete remission 92.4%; early progression 2.2%; progression/relapse 7.8% (6.6% and 8.5%). A total of 156 (9.9%) deaths (72 vs 84) have been observed (22 vs 32 acute or salvage treatment toxicity; 15 vs 24 HL; 22 vs 13 secondary neoplasia). Most treatment related deaths occurred in the &gt;60 years age group, the first 4 cycles and the IPS&gt; 3 RF groups. Secondary neoplasias were observed in 77 patients (4.9%): AML/MDS 1.5% vs 1.4%, NHL 1.4% vs 0.6% and solid tumors/others 2.5% vs 2.3%. At 5 years, OS was 91%, FFTF 85.5% and progression free survival (PFS) 86.2% (Kaplan- Meier estimates). Estimates for the difference at 5 years are 1.8% for OS, 2.3% for FFTF and 2.7% for PFS favoring BE. However, there was no statistical difference between 8x BE and 4BE+4BB in all outcome parameters (p&gt;0.19, log rank test). There is also no significant difference between the RT or no-RT arms in this study with the caveat that a number of high-risk patients receiving RT based on the blinded panel decision. Conclusion: The adoption of 4BE+4BB as a new standard in the future GHSG studies will depend on a refined analysis of the total data set and will be presented.

Abstract Abstract 1711 Background: Mutations in genes of the splicing machinery, such as SF3B1, SRSF2 and U2AF35 are common in patients with myelodysplastic syndromes [MDS] (Nature 2011;478:64) and chronic myelomonocytic leukemia [CMML] (Haematologica 2012;Epub). In MDS, SRSF2 gene mutations are an independent risk factor for shortened over-all (OS) and leukemia-free survival (LFS) (Blood 2012;119:3578). In MDS with ring sideroblasts (RS), SF3B1 mutations have a high prevalence (∼50%), but do not influence either, the OS or the LFS (Blood 2012;119:569). We carried out this study to evaluate the prevalence, clinical correlates and prognosis of the aforementioned spliceosome mutations in CMML. Methods: The study included 227 patients with WHO defined CMML who were seen at the Mayo Clinic from 1997 through 2007. All patients underwent bone marrow (BM) examination and cytogenetic evaluation at diagnosis. DNA was interrogated in the three most frequent spliceosome genes with somatic mutations; SRSF2, SF3B1 and U2AF35. Results I: Prevalence and clinical correlates Among the 227 study patients, 153 (67%) were male, median age was 71 years (range, 17–90 years) and 192 (85%) met the WHO criteria for CMML-1. Ninety (40%) patients had SRSF2 mutations (86% CMML-1), 13 (6%) had SF3B1 mutations (75% CMML-1) and 20 (9%) had U2AF35 mutations (95% CMML-1). One-hundred and twenty three (54%) patients had at least one of three spliceosome mutations (86% CMML-1). Mutational hot spots were P95 for SRSF2 (P95L-n=36/H-n=32/R-n=13/A-n=1), K700E (n=7) and H662Q (n=2) for SF3B1, and Q157 (Q157R-n=5/P-n=5/G-n=1) and S34F (n=7) for U2AF35. Seven patients (54%) with SF3B1 mutations had ≥1% RS, with 5 (38%) showing ≥15% RS. Mutations involving all three spliceosome genes were mutually exclusive. The cytogenetic distribution based on the Spanish risk stratification system (Haematologica 2011;96:375) was; SRSF2 mutations: 69 (77%) low risk, 11 (12%) intermediate risk, and 10 (11%) high risk (+8-n=3, del/monosomy 7-n=2, monosomal karyotype-n=5); SF3B1 mutations: 8 (62%) low risk and 5 (38%) intermediate risk; U2AF35 mutations: 15 (75%) low risk, 3 (15%) intermediate risk and 2 (10%) high risk (p=0.89). The distribution of mutations according to the MD Anderson prognostic scoring system [MDAPS] (Blood 2002;99:840) was; SRSF2 - low-n=41, intermediate-1-n=26, intermediate-2-n=18, high-n=5, SF3B1- low-n=7, intermediate-1-n=3, intermediate-2-n=2, high-n=1, and U2AF35- low-n=11, intermediate-1-n=5, intermediate-2-n=3, high-n=1 (p=0.73). There was no statistically significant difference, among the three mutation groups, in prognostically relevant parameters, including gender distribution, median age, hemoglobin values, platelet counts, peripheral blood (PB) and BM blast counts, absolute neutrophil counts (ANC) and absolute monocyte counts (AMC). The only notable difference was that patients with the SF3B1 mutation had a lower median white blood cell count (p=0.04) and a lower absolute lymphocyte count (p=0.045). Results II: Prognostic impact of spliceosome mutations At a median follow-up of 15 months, 166 (73%) deaths and 33 (14.5%) leukemic transformations were documented. Median survivals for patients with mutations involving SRSF2, SF3B1 and U2AF35 were 24, 17 and 12 months, respectively. In univariate analysis, the presence of SRSF2 (p=0.67), SF3B1 (p=0.96) or U2AF35 (p=0.49) mutations had no prognostic impact on OS. Similarly, none of the three spliceosome mutations affected LFS; corresponding p values were 0.55 for SRSF2, 0.9 for SF3B1 and 0.38 for U2AF35 mutations respectively. We then examined possible prognostic value of having none of these mutations (n=104) vs otherwise (n=123) and the results were once again negative (p=0.87). Conclusions: SRSF2 is the most frequently mutated spliceosome gene in CMML, but neither it nor SF3B1 or U2AF35 mutations affect overall or leukemia-free survival in CMML. Furthermore, the current study suggests limited genotype-phenotype association, save for the already established association between SF3B1 mutations and RS. Disclosures: No relevant conflicts of interest to declare.

5517 Background: The 2-year results of Intergroup RTOG 91–11 were published in 2003 (NEJM 349:2091–8,2003). We now present the 5-year results (after median follow-up for surviving patients of 6.9 years) of 515 eligible pts with resectable stage III or IV (excluding T1 and high volume T4), cancer of the glottic or supraglottic larynx. Methods: Patients were randomized to induction cisplatin/5-FU (CF) with responders then receiving RT (I+RT) (n = 173); or concurrent cisplatin (100 mg/m2 q 21 days × 3) and RT (CRT) (n = 171); or RT alone (R) (n = 171). Laryngectomy was performed for < partial response to induction CF, for persistent/recurrent disease or for laryngeal dysfunction. Results: At 5 years, laryngectomy-free survival (LFS) was significantly better with either I+RT (44.6%, p = 0.011) or CRT (46.6%, p = 0.011) compared to R (33.9%). There was no difference in LFS between I+RT and CRT (p = 0.98). Laryngeal preservation (LP) was significantly better with CRT (83.6%) compared to I+RT (70.5%, p = 0.0029) or R (65.7%, p = 0.00017). Local-regional control (LRC) was significantly better with CRT (68.8%) compared to I+RT (54.9%, p = 0.0018) or R (51%, p = 0.0005). I+RT compared to R for LP and LRC showed no significant difference (p = 0.37 and 0.62, respectively). The distant metastatic rate was low (I+RT 14.3%, CRT 13.2%, R 22.3%) with a trend (p ∼0.06) for benefit from chemotherapy. Disease-free survival (DFS) was significantly better with either I+RT (38.6%, p = 0.016) or CRT (39%, p = 0.0058) compared to R (27.3%). Overall survival rates were similar for the first 5 years (I+RT 59.2%, CRT 54.6%, R 53.5%); thereafter I+RT had a non-significant lower death rate. Compared to CRT, significantly more pts in the R group died of their cancer (34% vs 58.3%, p = 0.0007); the rate for I+RT was 43.8%. Conclusion: These 5-year results differ from the 2-year analysis by a significant improvement in LFS now seen for both I+RT and CRT treatments compared to R. For the endpoints of LP and LRC, CRT is still the superior treatment with no advantage seen to the addition of induction CF to R. There is no significant difference in overall survival.

8564 Background: Patients (pts) with peripheral T/NK cell lymphomas (PTCL) and intermediate-high/high IPI risk have a 5-yr overall survival < 20%. Current chemotherapy is unsatisfactory while benefit of upfront autologous transplantation (ASCT) is limited by high pre-transplant progression rates and pts advanced age. We evaluated efficacy and stem cells (SCs)-mobilizing activity of a biweekly regimen of gemcitabine (G), ifosfamide (Ifo) and oxaliplatin (Ox) (GIFOX), as an upfront strategy ensuring fast cytoreduction and early ASCT access or an effective alternative to CHOP-like programs in transplant-inelegible pts. Methods: Six biweekly courses of GIFOX [G 1000 mg/m2 D1, Ox 130 mg/m2 D2, Ifo 5 g/m2 D2 as 24h infusion (fractionated over days 2-4 in pts>65 yrs), G-CSF DD 7-11] were planned for all pts, with SCs mobilization at course 3 in ASCT-eligible pts. Simon's minimax two-stage design was adopted with the primary and secondary endpoints of response rate (RR) and progression-free survival (PFS), respectively. Results: Thirty-four pts (median age 63 yrs, r 42-80) [PTCL, nos (n=16), AITL (n=7), extranodal NK/T-cell (n=5), SS (n=6)], with IPI score intermediate-high (62%) or high (38%) were accrued [stage IV: 71%; BM involvement: 38%; E-site >1: 47%; hi LDH: 71%; ECOG>1: 38%; B-symptoms: 44%]. A total of 172 courses was delivered (median 6, r 2-6). Only 5 pts received <4 courses, due to progression (n=4) or early death (n=1). Overall RR was 82% [95% CI, 66-92; 22 complete (CR) and 6 partial (PR) responses]. Twelve pts mobilized SCs (median CD34+ cells harvest: 4.36x106/kg) and 8 (7CRs,1PR) underwent ASCT, 6 to 13 weeks after the 6th course. Estimated 5-yr PFS was 48% (95%CI: 28-65); median PFS for non-transplanted pts was 15 mo.s. Estimated 4-yr disease-free survival was 58%. Relevant toxicities were G4 thrombocytopenia (13%), G4 anemia (23%), G3/G4 infection (29%/6%), G3 encephalopathy (6%). Conclusions: Response and survival rates of GIFOX in high-risk PTCL compared more than favorably to CHOP-based regimens. Effective cytoreduction and prompt access to ASCT were ensured, together with safe delivery of a full induction program to transplant-ineligible pts.
