6087 Background: SAP (TAK-228, MLN0128) is a selective dual inhibitor of mammalian target of rapamycin complexes 1 and 2. In endometrial tumor xenograft models, SAP+PAC exhibited stronger antitumor efficacy than PAC alone. Methods: Female pts with histologic/cytologic diagnosis of endometrial cancer were randomized to receive SAP 4 mg by mouth (days [d] 2–4, 9–11, 16–18, 23–25) plus PAC 80 mg/m2 intravenously (d 1, 8, 15), or PAC alone, in 28-day cycles until unacceptable toxicity or disease progression. Randomization was stratified by histologic subtype, lines of prior chemotherapy (1 vs. 2), and prior taxane therapy. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS), overall response rate (ORR), clinical benefit rate (CBR; ORR + stable disease), and safety. Additional treatment arms of SAP alone (weekly dosing) and SAP+TAK-117 were closed after futility analyses. Results: 180 pts were randomized to SAP+PAC (n=90) or PAC (n=90); 86 and 87 pts received SAP+PAC and PAC, respectively; 3 pts from each arm were ongoing on treatment at data cut (30 July 2019). Baseline characteristics were balanced between arms. After a median follow-up of 17.2 vs. 14.4 mos with SAP+PAC vs. PAC, median PFS was 5.6 mos vs. 3.7 mos (hazard ratio [HR] 0.82; 95% CI 0.58–1.15). In pts with endometrioid histology (n=116), median PFS was 5.7 mos with SAP+PAC vs 3.3 mos with PAC (HR 0.66; 95% CI 0.43–1.03). In pts with nonendometrioid histology (n=64), median PFS was 3.6 mos with SAP+PAC vs. 5.4 mos with PAC (HR 1.09; 95% CI 0.62–1.90). Median OS was 13.7 mos with SAP+PAC vs. 14.6 mos with PAC (HR 1.01; 95% CI 0.67–1.53). Confirmed ORR was 24% with SAP+PAC vs. 18% with PAC (endometrioid, 23% vs. 16%; nonendometrioid, 28% vs. 22%); CBR was 80% vs. 58% (endometrioid, 84% vs. 55%; nonendometrioid, 72% vs. 63%). Median number of cycles received was 5 (range 1–23) with SAP+PAC and 4 (range 1–37) with PAC. Rates of grade ≥3 treatment-emergent adverse events (TEAEs) were 90% with SAP+PAC vs. 54% with PAC; the most common included anemia (21% vs.12%), neutropenia (12% vs. 3%), fatigue (12% vs. 5%), hypophosphatemia (12% vs. 1%), and pulmonary embolism (11% vs. 3%). Conclusions: Median PFS was longer with SAP+PAC vs. PAC in pts with endometrial cancer but did not reach statistical significance. PFS was particularly longer in the endometrioid subtype but again was not significant, and further studies are warranted. Incidence of grade ≥3 TEAEs was higher with SAP+PAC vs. PAC, but SAP+PAC toxicity was manageable, with no new safety signals. Clinical trial information: NCT02725268.

7503 Background: KRAS mutations are the most common (~20%) oncogenic alteration in NSCLC. There are no effective targeted therapies for this subset of NSCLC. Selumetinib (AZD6244, ARRY-142866) inhibits MEK1/2 signaling downstream of KRAS. We prospectively evaluated SEL + DOC vs DOC + placebo in advanced KRAS mutant NSCLC based on preclinical observations (NCT00890825). Methods: Patients (pts) with stage IIIB-IV, KRAS mutant NSCLC, who had received prior chemotherapy, received iv DOC 75 mg/m2, and po SEL 75 mg or placebo BD. The primary endpoint was overall survival (OS); secondary endpoints included: progression-free survival (PFS), objective response rate (RR), duration of response, change in tumor size, proportion of patients alive and progression-free at 6 mo, and safety and tolerability. Results: Between April 2009 and June 2010, 422 pts were screened across 67 centers in 12 countries; 113 had KRAS mutant NSCLC and 87 were randomized (DOC, 43; SEL/DOC, 44). Baseline characteristics were balanced (DOC vs SEL/DOC): WHO PS 0, 49%/48%; Female, 54%/52%; KRAS codon 12, 90%/93%. Median number of cycles: DOC, 4; SEL/DOC, 5. Most frequent grade 3/4 hematologic toxicity (DOC vs SEL/DOC): neutropenia (54.8%/67.4%), febrile neutropenia (0%/15.9%); most frequent grade 3/4 non-hematologic toxicity: dyspnea (11.9%/2.3%) asthenia (0%/9.1%), respiratory failure (4.8%/6.8%), acneiform dermatitis (0%/6.8%). Discontinuation due to AEs was similar: 18.2% SEL/DOC vs 11.9% DOC. OS was longer for SEL/DOC vs DOC (9.4 mo vs 5.2 mo; 56 events, median follow-up 219 days) but did not reach statistical significance; hazards were non proportional (HR 0.80; 80% CI 0.56, 1.14; 1-sided p=0.2069). All secondary endpoints, including RR (DOC 0%, SEL/DOC 37%; p<0.0001) and PFS (DOC 2.1 mo, SEL/DOC 5.3 mo; 71 events; HR = 0.58; 80% CI 0.42, 0.79; 1-sided p=0.0138), were significantly improved for SEL/DOC vs DOC. Conclusions: This is the first prospective study to demonstrate a clinical benefit of a targeted therapy (SEL + DOC) for patients with KRAS mutant cancer of any type. Our findings could have implications for the treatment of NSCLC and other KRAS mutant cancers.

Summary LY3023414 is an oral, selective adenosine triphosphate-competitive inhibitor of class I phosphatidylinositol 3-kinase isoforms, mammalian target of rapamycin, and DNA-protein kinase in clinical development. We report results of a 3 + 3 dose-escalation Phase 1 study for twice-daily (BID) dosing of LY3023414 monotherapy in Japanese patients with advanced malignancies. The primary objective was to evaluate tolerability and safety of LY3023414. Secondary objectives were to evaluate pharmacokinetics and to explore antitumor activity. A total of 12 patients were enrolled and received 150 mg (n = 3) or 200 mg (n = 9) LY3023414 BID. Dose-limiting toxicities were only reported at 200 mg LY3023414 for 2 patients with Grade 3 stomatitis. Common treatment-related adverse events (AEs) across both the dose levels included stomatitis (75.0%), nausea (66.7%), decreased appetite (58.3%), diarrhea, and decreased platelet count (41.7%), and they were mostly mild or moderate in severity. Related AEs Grade ≥ 3 reported for ≥1 patient included anemia, stomatitis, hypophosphatemia, and hyperglycemia (n = 2, 16.7%). Two patients discontinued due to AEs (interstitial lung disease and stomatitis). No fatal events were reported. The pharmacokinetic profile of LY3023414 was characterized by rapid absorption and elimination. Five patients had a best overall response of stable disease (150 mg, n = 3; 200 mg, n = 2) for a 55.6% disease control rate. LY3023414 up to 200 mg BID is tolerable and safe in Japanese patients with advanced malignancies.

e19506 Background: Many patients (pts) with B-cell malignancies require continuous treatment with Bruton tyrosine kinase inhibitors (BTKi). Adverse events (AEs) are a common reason for ibrutinib (ibr) or acalabrutinib (acala) discontinuation. Early data from BGB-3111-215 showed zanubrutinib (zanu) was well tolerated in pts with B-cell malignancies intolerant to ibr or acala. We report preliminary results with a median follow-up of 4.2 mo. Methods: Pts meeting protocol criteria for intolerance to ibr, acala or both (without documented progressive disease) were given zanu monotherapy (160 mg twice daily or 320 mg once daily). Recurrence of AEs that led to intolerance of prior BTKi and additional safety measures were assessed based on the Common Terminology Criteria for AEs v5.0. Investigators determined responses using disease status at study entry as baseline. Results: As of November 1, 2020 (cutoff), 44 pts (n=34 chronic lymphocytic leukemia/small lymphocytic lymphoma, n=6 Waldenström macroglobulinemia, n=2 mantle cell lymphoma, n=2 marginal zone lymphoma) were enrolled, received ≥1 dose of zanu, and analyzed for safety. Median age was 70.5 y (range, 49-91); median duration of treatment was 4.2 mo (range, 0.1-12.6). Median number of prior regimens was 2 (range, 1-12). Regarding prior BTKi, 39 pts received ibr only, 4 received ibr and acala, and 1 received acala only. The median number of ibr- or acala-intolerant AEs per pt was 2 (range, 1-5). 83% of ibr and 78% of acala intolerant events did not reccur on zanu; Table. At data cutoff, 43 pts remained on treatment; 1 withdrew consent due to zanu-unrelated grade 3 syncope. Overall, 34 pts (77.3%) reported any AE; most commonly reported AEs were myalgia (n=9; 20.5%), contusion (n=8; 18.2%), dizziness (n=7; 15.9%), fatigue (n=7; 15.9%), and cough (n=5; 11.4%). Grade ≥3 AEs were reported in 6 pts (13.6%), serious AEs in 1 pt (2.3%, febrile neutropenia and salmonella infection), AEs requiring dose interruptions in 6 pts (13.6%), and AEs leading to dose reduction in 2 pts (4.5%). No AEs led to zanu discontinuation. No deaths were reported. All efficacy evaluable pts (26/26 [100%]) maintained (10 [38.5%]) or achieved deepening (16 [61.5%]) of their response. Conclusions: Zanu provides an additional treatment option after intolerance to other BTKi, demonstrating tolerability and sustained or improved efficacy. Updated results will be presented.

Aims and background This prospective, phase II study aimed to test the efficacy of concurrent 5-fluorouracil, mitomycin C and radiation, with or without brachytherapy, on the clinical outcome of a series of recurrent endometrial cancer patients and to determine the prognostic impact of a subset of factors. Methods Thirty patients with locally recurrent, nonmetastatic endometrial cancer received external beam radiation (4-week split course: 23.4 + 23.4 Gy) plus two courses of concomitant chemotherapy (5-fluorouracil, 96-h continous infusion, days 1-4; 1 g/m2/day; mitomycin C, 10 mg/m2, bolus iv, day 1). Nineteen patients (63.3%) underwent endocavitary, low-dose brachytherapy boost (20-25 Gy); eight patients (26.7%) received external beam radiation boost (14-20 Gy). Results Eleven complete responses (36.7%), 11 partial responses (36.7%), 6 disease stabilizations (20.0%) and 2 progressions (6.6%) were observed. After a median follow-up of 27 months (range, 1-108), overall actuarial 3-year survival, progression-free survival and local progression-free survival were 46.8%, 35.2% and 41.2%, respectively. Two patients (6.7%) experienced hematological grade 3 toxicity. Two patients (6.7%) had grade 3 intestinal toxicity. Severe late toxicity was infrequent, only 3 patients showing severe vaginal stenosis (10.0%). A clinical score of 0 to 1 was assigned to each patient on the basis of the absence (score = 0) or presence (score = 1) of any of the following prognostic factors: time between surgery and recurrence shorter than 12 months, pelvic wall site of recurrence, positive lymph nodes, hemoglobin <11 g/dL. With this device, it was clear that patients with a low score had a significantly better outcome (clinical remission: 77.2% of patients with a score <2 vs 25.0% of patients with a score ≥2, P = 0.009), better local control of the disease (50.2% vs. 0 at 3 years, P = 0.014,) and better overall survival (65.8% vs 0 at 3 years, P = 0.003). Conclusions Our data suggest that this combined modality therapy was relatively well tolerated and resulted in reasonable local control and survival. The scoring system proved to be helpful in identifying patients with the best chance of benefiting from the treatment.

Abstract The FLIPI has recently been demonstrated to correlate with survival in patients (pts) with newly diagnosed follicular lymphoma (FL). No such index has been developed or evaluated to predict outcome for FL pts in the setting of myeloablative therapy and ASCT, despite data suggesting that ASCT may improve overall and progression-free survival (PFS). We examined the factors that contribute to the FLIPI as well as other factors assessed at time of transplant for their association with overall survival (OS) in 189 pts undergoing ASCT for FL. Baseline characteristics included: median age = 47 years (range, 24 – 64), stage III–IV = 94%, &gt;4 nodal areas = 7.7%, elevated LDH = 30%, &gt;5 cm maximal bulk of disease = 18%, chemoresistant disease = 13%, median number of prior chemotherapy regimens = 2. The FL histologies included: Grade 1 (49%), Grade 2 (31%), Grade 3 (13%), and transformation to diffuse large B-cell lymphoma (6%). Patients were conditioned with chemotherapy-only (21%), chemo+TBI (45%), or radioimmunotherapy +/− chemo (34%). Among all pts, the five-year estimated OS and PFS are 58% and 39%, respectively, with a median follow-up among surviving pts of 8 years (range, 1 – 18). The five factors that were found to be most significantly associated with OS include two FLIPI factors [age, hazard ratio for death (HR) = 1.37 per ten-year increase in age; elevated LDH, HR = 1.57] and three other clinical factors [&gt;1 maximal extranodal site of disease, HR = 1.67; ≥2 prior chemotherapy regimens, HR = 1.99; chemoresistant disease, HR = 2.8]. Patients with 0 – 1 adverse factors (with age dichotomized as &lt; 45 vs. ≥ 45) had an estimated 5-year OS of 79%, those with 2 factors 50%, 3 factors 41%, 4 or 5 factors 13% (Figure). Although prospective validation of this proposed model is required, this approach may be used to counsel FL pts regarding expected outcome following ASCT, to compare data between trials, and to design future studies.

Abstract Temsirolimus (CCI-779, Wyeth Pharmaceuticals) has been shown to inhibit proliferation of a variety of tumors and induce G1 cell cycle arrest by preventing activation of the serine/threonine kinase, mTOR (mammalian target of rapamycin), a downstream effector of the PI3K/Akt pathway. Several lines of evidence implicate the PI3K/Akt/mTOR pathway in hematological malignancies. Interim results of a phase II study evaluating the efficacy and toxicity of single-agent temsirolimus in patients with advanced malignancies are presented. Temsirolimus was administered weekly, at a flat dose of 25 mg, as a 30-minute intravenous infusion. Treatment was continued until evidence of disease progression or unacceptable toxicity. To date, 8 patients have been enrolled and 7 are evaluable for efficacy and toxicity (one patient did not receive temsirolimus). Of these 7 patients, 5 had AML, 1 CML-myeloid blast crisis, and 1 ALL. Median age was 68 years (range, 21 to 87 years) and 5 were male. All patients had received prior therapy, median 2 regimens (range, 1 to 3 regimens). The median number of temsirolimus doses administered was 3 (range, 1 to 10) with a median time on study of 18 days (range, 3 to 89+ days). The most common temsirolimus-related adverse events were grade ≤ 2 and consisted of anorexia, nausea and/or vomiting and diarrhea, mucositis, dermatitis, hypertriglyceridemia, hyperglycemia, hypomagnesemia, hypocalcemia, hypokalemia, hypophosphatemia, and fatigue/asthenia. No patient developed nonspecific pneumonitis. Grade 3 toxicities included fatigue/asthenia (2), hyperglycemia (1), painful mucositis with dehydration and electrolyte abnormalities (1), diarrhea with hypokalemia (1), and hypophosphatemia (1). No patient experienced grade 4 toxicities or death from temsirolimus. No patient required dose reductions, but 2 did have dose delays due to grade 3 mucositis (1) and out-of-state hospitalization for pneumonia and atrial fibrillation (1). No patient achieved a complete remission. One patient with heavily pre-treated Philadelphia-negative precursor B-cell ALL had a transient 79% to 91% reduction in peripheral blood blasts 4 days after the first dose of temsirolimus that was maintained for 12 days prior to disease progression with involvement of the synovial fluid in bilateral knees. At the time of analysis, 6 of the 7 patients have discontinued treatment due to disease progression (4), patient refusal (1), or physician decision (1). Preliminary findings indicate that temsirolimus is relatively well-tolerated at a dose of 25 mg per week and may have biologic activity in ALL. Accrual onto the study is currently ongoing.

Abstract Abstract 2704 Background: MR has improved the outcome and progression-free survival (PFS) in patients with follicular lymphoma (FL) in front-line and relapsed settings. However, maintenance schedules have been empirically designed based on either B-cell depletion kinetics or rituximab levels, with no consensus on the optimal regimen. Overall, toxicities have been predictable and tolerable but the impact of MR schedule on toxicities has not been previously reported and could influence selection of maintenance regimens. Methods: Using PubMed, prospective clinical trials employing MR were identified. Data presented in abstract form or at meetings were deemed incomplete and thus excluded. Data were analyzed from published manuscripts as percentages of subjects experiencing an adverse event (AE). Percentages were considered as the unit of analysis as this adjusted for the uneven sample sizes. Data were collected for overall Grade 3 and/or Grade 4 toxicity (AE reported at any phase of treatment) and was further categorized as AE occurring during initial treatment or during MR. Grade 1 and 2 toxicities were excluded from meta-analysis, given lack of consistent reporting. No grade 5 toxicities were reported. The incidence, severity, and type of toxicity was analyzed by type of induction (Rituximab (R) vs. R plus chemotherapy), histology (FL vs. FL plus other LG-NHL), setting (front-line vs. relapsed), and MR schedule (one dose every 2 months vs. one dose every 3 months vs. 4 doses every 6 months). Results: Nine clinical trials involving 1,928 patients were included in this Meta analysis (4 of which were randomized controlled in the MR phase). Of those, 1,004 patients received MR. The mean percentage of Grade 3/4 toxicities during any phase of treatment was 26% (95% CI = 0.12–51.88) but when restricted to the MR phase; it was 12.88% (95% CI = 6.50–19.26). Toxicities were numerically higher in patients receiving R induction plus chemotherapy versus R induction alone and in patients receiving MR for relapsed disease versus newly diagnosed patients, but did not reach statistical significance (P = 0.661 and 0.517, respectively). However, patients receiving MR every 2 months were significantly more likely to develop grade 3 and 4 toxicities compared to patients receiving MR every 6 months (P = 0.005). No statistical differences were demonstrated between the 2 vs. 3 months schedules or when comparing the 3 vs. 6 months schedules (P = 0.342 and 0.267, respectively) (Table 1). Statistically significant differences were also found in studies restricted to FL versus others allowing non-FL histologies (P = 0.025) with the FL patients experiencing more toxicity than others. The most frequently reported toxicities were neutropenia and infections. There were no treatment-related deaths in any of the arms. Conclusions: Approximately 13% of patients receiving MR experience grade 3 and/or 4 toxicities, mainly consisting of neutropenia and infections. MR given every 6 months appears to provide the least grade 3 and 4 toxicities. There is a suggestion of increased toxicity in FL histologies. It is important to note that this meta-analysis did not address efficacy and only a true comparative trial can definitively establish the relative risk/benefit ratios amongst MR schedules.

Abstract Abstract 2860 Introduction: In the last decade, important progress has been achieved in the treatment of CLL through the use of purine analog-based chemoimmunotherapies. Several conditions remain a challenge, often with a poor outcome. Amongst these therapeutic problems are Richter's transformation (RT), refractoriness to F-based therapies (Fref), and the occurrence of AIC, which are sometimes induced by F. Fref and RT pts have a very poor prognosis with an estimated overall survival (OS) of only 10 and 8 months (mos), respectively. Therefore, therapeutic alternatives are urgently warranted. CHOP-R has improved the outcome of pts with aggressive non-Hodgkin's lymphoma. To test the efficacy and tolerability of the CHOP-R regimen in CLL patients with RT, Fref, or AIC, the GCLLSG initiated a prospective phase II trial. Material and Methods: 62 patients were included in the study. Due to protocol violations, 2 patients were excluded. Within the group of Fref pts, the medical review detected 11 patients who had received pre-treatment with F (Fpret), but were not refractory according to the updated guidelines (Hallek et al., Blood 2008). Thus, 26 pts were classified as Fref/pret, 19 pts as AIC and 15 pts as RT. All patients received CHOP every 3 weeks (cyclophosphamide 750mg/m2, adriamycin 50mg/m2 and vincristine 1, 4mg/m2 d1; prednisone 100mg/m2 d1–5). Rituximab was added starting with the 2nd cycle (375mg/m2 on each d0, and 21 days after the last CHOP-R). RT pts received up to 8, Fref/pret and AIC up to 6 courses of CHOP-R. In case of PD after 3 cycles, pts went off-study. The primary endpoints were remission rate, quality and duration of response. Results: 79%, 73%, and 40% of AIC, Fref/pret, and RT pts were male, respectively. The median age was 65 years (y) for Fref/pret-pts, 66y in the AIC and 69y in the RT group. Binet stages for Fref/pret pts were: A: 8%; B: 27% C: 65 %. All but 3 AIC pts were at Binet stage C. Initial RT stages according to Ann Arbor were: II: 13%, III: 13%, IV 73%. The median number of previous therapies were 3 for Fref/pret, 2 for AIC and 2 for RT. A total of 314 cycles were administered, with a median number of 3 cycles for AIC and Fref pts and a median number of 4 cycles for the RT group. Due to toxicity 73% of cycles in the Fref/pret group, 66% in the AIC and 87% in the RT group were dose-reduced. 69% of Fref/pret-pts and 58% of AIC-pts received full 6 cycles of therapy and only 40% of RT-pts completed 8 cycles of therapy. Treatment was stopped in 6 pts because of PD. Due to treatment related toxicity treatment was stopped in 16 pts (27%). Treatment related mortality was 3% (2 pts). Treatment toxicity was reported according to NCI common toxicity criteria (CTC) version 2.0. Adverse events grade 3 or 4 for anemia, neutropenia and thrombocytopenia were documented in 75%, 55% and 65% of patients, respectively. Infections were the most common non-hematologic toxicity and occurred in 67%; severe infections CTC grade 3 or 4 occurred in 28%. All 26 Fref/pret-pts were available for response evaluation. CHOP-R achieved 54% PR, 35% SD and 12% PD. The median progression-free survival (PFS) and median treatment-free survival (TFS) were 11 and 14 mos. OS was 27 mos with a significant difference concerning F-ref (n=15) and F-pret (n=11) pts (17 vs. 35m; p=0.05). We evaluated the response of all 15 RT-pts with 60% PR, 7% CR, 13% SD and 20% PD. The PFS was 15 mos, TFS was 17 mos and OS 27 mos. 17 AIC pts were available for response evaluation with 82% PR, 6% SD and 12% PD. The PFS and TFS were only 14 and 16 mos. The OS was 50 mos. The population had a high incidence of unfavourable genetic markers: deletion of chromosome 17p [del(17p)] was detected in 24%, del(11q) in 34% and unmutated IGHV in 70%. 85% had high levels of serum thymidine kinase (sTK > 10 U/l), and 49% had high levels of ß2-microglobulin (ß2M > 3.5 mg/l). Patients with del(17p) had an unfavourable response rate and achieved significant less a PR or CR (36% vs. 76%; p=0.03). Multivariate analyses showed that del(17p) and ECOG performance status had a negative prognostic impact on OS (p<0.0001). Moreover the presence of a del(17p) predicted a short PFS (6 vs. 16.9 mos; p=0.001). Conclusion: CHOP-R achieves promising response rates in CLL patients with Fref and RT and very good response rates in patients with AIC. However, the progression-free survival and overall survival remain unsatisfactory. Therefore, CHOP-R might be used as induction therapy prior to allogeneic stem cell transplantation in physically fit patients.

5089 Background: Despite of the effectiveness of radical surgery and first-line chemotherapy, most patients (pts) with advanced ovarian cancer will relapse. Paclitaxel (P) in combination with C as second-line treatment improves the outcome of pts with platinum-sensitive ROC in comparison to C monotherapy. Due to polyneuropathy and alopecia this regimen can not be offered to all pts. Therefore, other platinum-combinations are required. We conducted a phase I/II study to define the dose limiting toxicities (DLT) and the tolerability of combination therapy with T and C. Methods: Pts with platinum-sensitive ROC and primary standard therapy were stratified according to treatment-free interval (TFI): 6–12 months (A) and ≥12 months (B). Following dose regimens were analysed: T 1mg/m2/d1–3 + C AUC5/d3 and T 0.75 mg/m2/d1–3 + C AUC5/d3, q21d. DLT was based on the first 4 courses and defined as: CTC grade 3/4 hematological and grade 2 non-hematological toxicity (excepted alopecia, vomiting), treatment delay >7d. Primary endpoints were DLT and tolerability. Secondary endpoints were remission rate (RR) and progression-free survival (PFS). Results: From 06/04 to 08/05, 28 pts were enrolled, 26 pts (A:13 pts, B:13 pts) were eligible. Median age was 61.5 years. A total of 141 cycles were analysed, median number of cycles was 6 (range A:2–8, B:1–10). DLTs were: leucopenia (n = 5) and thrombocytopenia (n = 1). MTD was reached at dose: T: 0.75mg/m2 and C: AUC5. Overall, grade 3/4 hematologic toxicities (in% of all cycles), for (A) and (B) respectively, were: anemia 4% vs. 4%, leucopenia 34% vs. 13%, neutropenia 30% vs. 31%, thrombocytopenia 7% vs. 6%. Febrile neutropenia 4.3% vs. 0%. Darbepoetin alfa was given in 13.5% of all cycles. Overall, grade 3/4 non-hematologic toxicities were infrequent (< 5%). Overall RR (95% CI) was 50% (29.7–70.1) [A: 30.8% (0.1–61.1), B: 69.3% (38.7–90.9)]. Median follow-up was 5.8 mo, median PFS (95% CI) was 7.7 mo (1.3–9.4) [A: 6.2 (1.3–7.2), B: 8.0 (7.3–9.4)]. Median overall survival was not reached. Conclusions: TC is a feasible and effective chemotherapy regimen for platinum sensitive ROC. Tolerability is not associated to TFI. The recommended dose for subsequent studies is T:0.75 and C:AUC5. No significant financial relationships to disclose.

16048 Background: To test the hypothesis that expression of osteopontin (OPN), an integrin-binding glycoprotein, can independently predict the potential aggressiveness of endometrial cancer. Methods: The status of OPN expression in benign and malignant endometrial cancer cell lines and tissues was analyzed by real time PCR, Western blot, and immunohistochemistry. Nonparametric Spearman's correlation coefficient method was used to assess the statistical significance of the correlation between clinicopathologic characteristics of tumor and OPN expression. Results: An increased expression of OPN was observed in the endometrial cancer compared to normal endometrial tissue samples. When the level of OPN in normal tissue was set at 1, its level in benign endometrial hyperplasia was slightly increased at 1.2, whereas the OPN level in the highly malignant endometrial carcinoma tissue was greatly increased by nearly 3–5 folds. Amongst the 160 cases examined immunohistochemically, of the 43 grade 1 endometrial carcinomas, 31 were unstained and 12 stained weakly positive (+). For the 41 grade 3 or serous type endometrial carcinomas analyzed, 25 (60%) stained strongly positive (+++), 8 (19%) stained moderately positive (++) and 4 (9%) stained weakly positive (+). These results showed that the level of OPN expressed between grade 1 and grade 3 or more was significantly different (Spearman's correlation coefficient method, p = 0.001). However, Kaplan-Meier survival analysis showed that the increased level of OPN expression was not significantly associated with reduced survival time of the patients. Conclusion: The results suggest that the increased OPN level may be involved in the malignant transformation of endometrial adenocarcinoma cells. No significant financial relationships to disclose.
