10062 Background: Trabectedin (T) is a marine-derived alkaloid used to treat advanced soft tissue sarcomas (STS) after ifosfamide and/or anthracyclins failure. Since then, the FSG evaluated the clinical benefit in re-administrating T after an initial hold, either medically indicated or upon patient’s request. Methods: Following an online request, clinical and histopathological data were collected from six centers of the FSG who declared to have rechallenged patients. Baseline data were collected and analyze will be used. Results: From 1999 to 2011, 49 pts with T drug holiday have been identified (26 male/ 23 female), with a median age of 50 y [23-75]. Most frequent histotypes were: myxoid liposarcoma (18, 36.7%), leiomyosarcomas (13, 26.5 %) and well-differentiated/dedifferentiated liposarcoma (9, 18%). WHO grade were 1 in 14 (29%), 2 in 19 (39%) and 3 in 5 (10%) pts respectively. Patients who had a maximum of 2, 3 or 4 therapeutic sequences (TS) with T (drug-holiday and rechallenge) were 41/49 ,7/49 and 1/49 respectively. Median number of cycles for 1, 2, 3 and 4 TS were 7 [3-21], 6 [2-30], 6 [2-9] and 6. Median total number of cycles was 15 [6-43]. Median duration of drug-holiday for 1, 2 and 3 TS were 11 [3-91], 7 [2-29] and 4 months [1-5]. Grade 3-4 toxicities incidence decreased with the number of TS (occurred in 36%, 29%, 14% and 0% of pts with 1, 2, 3 and 4 TS) as well as mean T dose per cycle (1.3 mg/m², 1.2 mg/m², 1.1 mg/m² and 1.1 mg/m² for TS 1, 2, 3, 4). Efficacy decreased with number of TS (Number of CR/PR/SD/PD were 1 (2%)/15 (31%)/33 (67%)/0 for TS1; 0/4 (8%)/29 (59%)/16 (3%) for TS2; 0/1 (14%)/2 (29%)/4 (57%) for TS3 and 0/0/0/1(100%) for TS4). Median overall survival was 5.0 y [2.7-7.3] since T introduction, and 1.5 y [0.1-4.8], 0.8 y [0.5-1.3] and 0.6 y following 2nd, 3rd and 4th T reintroduction respectively. Objective response after TS2 were seen in 4 cases of grade 1 sarcomas. Conclusions: Due to the lack of cumulative toxicities over time with T, its rechallenging in responding patients to T (no progression under T) have to be considered in advanced STS.

10039 Background: Ifosfamide (IFO) has recognised activity in soft tissue sarcomas. There is evidence for improved cytotoxicity and tolerability utilising a prolonged 14 day infusional outpatient regimen compared with the standard 3-day regimen (Loeffler et al 1990). We undertook a retrospective review of all patients treated with this regimen from September 2008 - December 2011 to determine toxicity and treatment response. Methods: Pts. were identified from our database and demographics, histological subtype, toxicity and survival outcomes were collected. IFO was given via central venous access using 2 x 7 day pumps at 1g/m2/day with mesna for 14 days q 4 weekly. Oral sodium bicarbonate was used to maintain alkaline urine with oral mesna for haematuria, and thiamine for symptoms of encephalopathy as required. Results: 29 patients (pts), with advanced sarcoma, median age 56 years (27-76 yrs), 14F 15 M, median number of cycles = 1 ( 1-9). At baseline: PS 0=1, 1=24, 2=4. 18 pts had de-differentiated liposarcoma (D-LPS), 6 synovial sarcoma, 5 had other subtypes. 12 pts received only 1 cycle, with 5 stopping due to encephalopathy. Ten patients developed encephalopathy, 9 occurring in cycle 1, other toxicity was tolerable, with Gr 2-3 nausea (15 pts) and vomiting (9pts) and only 2 Gr 3 episodes of myelotoxicity for all cycles. 4 patients achieved PR, (2 with D-LPS and 2 with Synovial sarcoma) 11 pts. had SD. Median PFS was 19 months and OS was 12.5 months. 2 pts. with D-LPS had a sustained prolonged response of 15 and 16 months. Conclusions: Infusional IFO is generally well tolerated; however a significant incidence of neurotoxicity was seen. Pts. with D-LPS demonstrated best response to treatment, a sarcoma subtype that has previously failed to respond to systemic therapy. This regime warrants further investigation.

10527 Background: An objective response rate (RR) of 8% and 17% with G and G+D were respectively reported in metastatic soft tissue sarcomas (Maki, J Clin Oncol. 2007). We previously reported a 5% RR in 41 evaluable patients (pts) with ‘non uterus‘ LMS randomized to each arm of this randomized phase II study (Duffaud, ASCO. 2008). We present here the results of G vs G+D in uterine and all LMS. Methods: Patients had histologically proven metastatic or unresectable LMS, one prior anthracycline- based regimen, age ≥18, measurable disease (RECIST), PS ≤ 2. Treatment was G 1,000 mg/m2(over 100 minutes, d1+d8+d15) q28 days (d) or G 900 mg/m2(over 90 min, d1+d8) and docetaxel 100 mg/m2 (over 60 min, d8) q21 days; in the G+D arm, pts received lenograstim d9–15, 25% dose reductions were employed for prior pelvic radiation. The primary endpoint was the objective RR (CR+PR), evaluated every 2 cycles. Stratification was by primary tumor location (uterus vs. non-uterus). The Simon method was used: for “uterus” study, 20 pts per arm for a 74% probability of selecting the arm with a real RR of 50%, expected baseline RR was 40%; for the “non-uterus” study, 20 pts per arm for a 92% probability of selecting the arm with a real RR of 40%, expected baseline RR was 20%. Results: From 02/06 to 12/08, 44 pts were enrolled in the “non-uterus” study, 40 pts in the “uterus” study. Currently 76/82 pts are evaluable for response (41/44 in the “non uterus” and 35/38 in the “uterus” study) and 80/84 for toxicity. In the uterus group the median age is 57 (range 41–80), 24 pts received prior pelvic radiotherapy, the median number of cycles was 5 (range 0–8) and dose received/dose planned (%) were 69% in G arm, 88% of G and 86% of D in G+D arm. No differences in toxicity were observed between both LMS locations: in the G arm, toxicity was moderate except for one pulmonary gr4; in the G+D arm one toxic death was related to gr5 thrombocytopenia and there were 2 non-haemathologic gr4 toxicities; 11 pts stopped for intolerable toxicity (3 in G and 8 in G+D arm) and 1 pt for hypersensitivity (G+D arm). Conclusions: Final tumor response for uterine LMS and updated toxicity and PFS data for all the LMS will be presented during the meeting. [Table: see text]

7098 Background: M (TL139, MAC-321) is a novel taxane that has shown activity when administered IV or orally in both taxane-resistant and susceptible nude mouse xenograft models. The current study is an open-label study in previously treated patients (pts) with locally advanced, metastatic, or recurrent NSCLC to determine response rate. Methods: Pts with cytologically or histologically confirmed NSCLC must have received 1 or 2 prior regimens including prior platinum, and may have received prior paclitaxel or docetaxel. Good performance status (ECOG 0 or 1), and adequate hematologic, hepatic and renal function were required. Pts with clinically active brain metastases were excluded. Pts were treated with M 35 mg/m2 as a 4 hr IV infusion every 3 weeks. The primary end point was objective response rate. Results: A total of 46 pts were treated: 21 (46%) female pts and 25 (54%) male pts. Mean age was 59 (range 41–85), ECOG was PS 0 in 13 (28%) pts, PS 1 in 31 (67%) pts and unknown in 2 (4%) pts. The number of prior chemotherapy regimens was > 1 in 21 (46%) pts. Twenty-five (54%) pts had one prior taxane and 7 (15%) pts had both paclitaxel and docetaxel previously. The median number of cycles was 3 (range 1–14). Nine (20%) pts required dose reduction. Five (11%) pts discontinued treatment due to adverse events. A total of 25 (54%) pts reported drug related grade 3 or 4 adverse events. Non-hematologic grade 3 or 4 drug-related events occurring in more than 1 pt included: neuropathy 4 (9%) pts, neutropenic fever 3 (7%) pts, arthralgia 2 (4%) pts. There was no treatment related mortality. Objective responses were confirmed in 4 (9%) pts (3 PR, 1 CR). Three pts with response (including pt with CR) had received prior docetaxel. PR duration was 175, 250, and 315 days. Pt with CR received 4 cycles of M and discontinued due to the CR. Pt remained in CR at day 504. Conclusions: Milataxel 35 mg/m2 as a 4 hr IV infusion every 3 weeks provided durable responses in heavily pretreated pts including pts who had previously received taxanes. No significant financial relationships to disclose.

Liposarcoma (LPS) is the most common soft tissue sarcoma. Myxoid LPS (MLPS) is the second most common subtype of LPS and accounts for 25% to 50% of all LPSs. Like most other soft tissue sarcomas, the mainstay of treatment for LPS is inevitably surgery. Multidisciplinary approaches, including surgery, chemotherapy, and radiotherapy, have been successful in the treatment of LPS during the last three decades. Even so, recurrence of LPS remains challenging. Carbon ion beams produce increased energy deposition at the end of their range to form a Bragg peak while minimizing irradiation damage to surrounding tissues, which facilitates more precise dosage and localization than that achieved with photon beams. Furthermore, carbon ion beams have high relative biologic effectiveness. We herein describe a patient who developed recurrent MLPS in the right calf after two surgeries and underwent carbon ion radiotherapy (CIRT), achieving complete disappearance of the tumor. The patient developed Grade 1 radiation dermatitis 30 days after CIRT, but no other acute toxicities were observed. The tumor had completely disappeared by 120 days after CIRT, and the patient remained disease-free for 27 months after CIRT. The CARE guidelines were followed in the reporting of this case.

Abstract Liposarcoma is one of the most common soft tissue sarcomas and has multiple subtypes, including atypical, well-differentiated, and dedifferentiated liposarcoma1. These tumors most commonly occur in the extremities and the retroperitoneum2, and account for 20% of all retroperitoneal tumors3. Retroperitoneal liposarcoma is very rare overall, occurring in 2.5 per one million people4. Patients will present from symptoms of mass effect due to the uncontrolled growth in the large potential space of the retroperitoneum, with its median size being around 30 cm5. The mainstay of treatment for this type of tumor is resection to a negative margin6. This is a case report describing a retroperitoneal liposarcoma presenting with bilateral inguinal hernias containing intraperitoneal fat from mass effect.

Summary Liposarcoma is one of the most common soft tissue sarcomas in adults with a relative incidence amongst other sarcomas ranging from 9.8% to 16%. It usually locates in the limbs and retroperitoneum. Primary liposarcomas of the larynx and hypopharynx are rare, comprising less than 20% of all head and neck liposarcomas. According to World Health Organization, these tumors are divided into four histologic types, and well-differentiated liposarcoma is the most common one. It is a tumor of low-grade malignancy that may recur locally, but does not metastasize. We present a case of laryngopharyngeal well- differentiated liposarcoma in an old patient with two previous removals. We also discuss recently published cases with this unusual location of liposarcoma.

415 Background: Immune checkpoint inhibitors (ICI) have been approved in solid tumors with dMMR. However, only limited data are available for PDAC with dMMR given the rarity of dMMR in PDAC. We evaluated efficacy of ICIs in PDAC with dMMR. Methods: Retrospective clinical and pathologic data were collected for patients (pts) with pancreatic adenocarcinoma from May 2017 to June 2020 at Moffitt cancer center. Results: We identified 10 pts with dMMR PDAC. The median age was 64.5 years (range: 42-86) and 4 pts were male. 4 pts had resectable disease, 3 had locally advanced and 3 had metastatic disease at initial diagnosis. MSH6 deficiency (def) was found in 2 cases, PMS2 def in 2, MLH/PMS2 def in 5, and MSH2/MSH6 in 1. 7 pts were treated with ICIs. 3 pts had locally advanced and 4 had metastatic disease when they started ICIs. 5 received Pembrolizumab (pem), 1 received ipilimumab/ nivolumab (ipi/nivo), and 1 received pem then ipi/nivo after progressive disease (PD) on pem. The median number of prior lines of chemotherapy was 1 (range 0-2). 6 pts were evaluable, and 1 had rapid disease progression after 1 dose of pem. Among 6 evaluable pts, 3 had an objective response (1: complete response and 2: partial response), and 2 had stable disease (SD). Median progression-free survival was 8.2 mo, and median overall survival was not reached with median follow-up (FU) of 6.8 mo. The median duration of response was not reached with a median FU of 22.6 mo. The pt with CR remained disease-free for up to 22 months. The pt whose treatment was switched to ipi/nivo after PD on pem achieved SD > 4mo on ipi/nivo. While on immunotherapy, one patient with ipi/nivo developed immunotherapy associated rash requiring systemic steroids, and another on pem developed hypothyroidism requiring levothyroxine. Conclusions: This series suggest ICIs can provide durable clinical efficacy in pts with dMMR PDAC.
