Line Setting

In the first-line setting of advanced soft tissue sarcomas (STS), the treatment aim generally drives decision-making. Anthracycline combinations with ifosfamide or dacarbazine are more appropriate when the aim is tumour shrinkage, and doxorubicin monotherapy is suitable for tumour control. In patients who progress on anthracycline-based regimens, scope exists for tumour shrinkage with trabectedin and concurrent low-dose radiotherapy. Selecting systemic treatment for patients with advanced STS unsuited to receive standard anthracycline-based therapy often involves complex decision-making as clinical trial evidence comparing alternative options is lacking. Key factors to consider are patient characteristics (e.g., age, medical history, performance status), disease characteristics (e.g., stage, histology), and treatment requirements such as the drug’s safety profile, evidence of efficacy by subtype, and approved indication as an alternative first-line treatment option. Real-world data for elderly STS patients derived from retrospective studies and post hoc analyses of clinical trials have particular value in guiding treatment selection and improving the management of this populous but undertreated segment of the STS population.

Real World Evidence

Real-world data are defined as data relating to any aspect of a patient’s health status collected in the context of routine health surveillance and medical care delivery. Sources range from insurance billing claims through to electronic surveillance data (e.g., activity trackers). Real-world data derive from large populations in diverse clinical settings and thus can be extrapolated more readily than clinical trial data to patients in different clinical settings or with a variety of comorbidities. Real-world data are used to generate real-world evidence, which might be regarded as a “meta-analysis” of accumulated real-world data. Increasingly, regulatory authorities are recognizing the value of real-world data and real-world evidence, especially for rare diseases where it may be practically unfeasible to conduct randomized controlled trials. However, the quality of real-world evidence depends on the quality of the data collected which, in turn, depends on a correct pathological diagnosis and the homogeneous behaviour of a reliably defined and consistent disease entity. As each of the more than 80 varieties of soft tissue sarcoma (STS) types represents a distinct disease entity, the situation is exceedingly complicated. Discordant diagnoses, which affect data quality, present a major challenge for use of real-world data. As real-world data are difficult to collect, collaboration across sarcoma reference institutions and sophisticated information technology solutions are required before the potential of real-world evidence to inform decision-making in the management of STS can be fully exploited.

Introduction Soft tissue sarcomas are a heterogeneous and rare group of cancers with a short median overall survival despite the chemotherapy. Pazopanib has approval for the treatment of advanced soft tissue sarcoma. We aimed to investigate the clinical outcomes of Turkish patients with advanced soft tissue sarcoma who received pazopanib. Patients and methods This was a retrospective study. The inclusion criteria were: ≥18 years of age, having histologically proven advanced soft tissue sarcoma and receiving pazopanib at least one day. Results A total of 79 patients were assessed in this study. The median age was 49.6 years. The average dose intensity of pazopanib was 767 mg (400–800). The median duration of pazopanib treatment was 6.11 months. Fourteen patients (17.7%) used pazopanib at first line for advanced soft tissue sarcomas. The most common cause of discontinuation of pazopanib was the progression of the disease (89.6%). Pazopanib was well tolerated. The most common grade ≥3 side effect was anemia. The most common grade ≤2 side effects were anemia and hyperbilirubinemia. The median progression-free survival, overall survival, and follow-up were 3.97 months, 11.40 months, and 32.72 months, respectively. Female gender, good performance status, and the presence of pazopanib-induced hypothyroidism were associated with longer progression-free survival. Also, good performance status and being a responder to first-line treatment were associated with longer overall survival. Conclusions We showed that pazopanib was well tolerated and had clinical benefit in patients with advanced soft tissue sarcoma in a Turkish cohort. This is the first study that suggests pazopanib-induced hypothyroidism may act as a predictive marker for better outcomes in patients with advanced soft tissue sarcoma.

7086 Background: AMR, a new anthracycline agent, has achieved some promising results for advanced SCLC both in the first-line and the second-line setting. However the efficacy of AMR alone against refractory relapsed SCLC was relatively low in previous studies. This study was conducted to evaluate the safety and efficacy of the combination of AMR plus CBDCA in patients with refractory relapsed SCLC. Methods: Patients with advanced SCLC who relapsed within 90 days after the completion of first-line chemotherapy received AMR (30 mg/m2, day1-3) and CBDCA (AUC 4.0, day 1) every 3 weeks. The primary endpoint of this study was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival and toxicity profile. Assuming that ORR of 45% in eligible patients would indicate potential usefulness while ORR of 20% would be the lower limit of interest, with alpha = 0.10 and beta = 0.10, at least 24 patients were required. Results: From September 2008 to May 2011, 30 patients were enrolled from 10 institutions. One patient was excluded because of ineligible histology. Patient characteristics were: Male/Female 26/3; median age 67 (range 50-81); Performance status 0/1/2 9/16/4. The median number of treatment cycles were 4 (range 1-7). The objective responses evaluated by RECIST were: CR 0, PR 10, SD 14, PD 5. The ORR was 34% and the disease control rate was 83%. Median PFS was 3.5 months and median survival time was 7.3 months. Grade 3-4 neutropenia was observed in 23 patients (79%) and grade 3-4 thrombocytopenia was observed in 7 patients (24%). One patient (3%) suffered from grade 3-4 febrile neutropenia. Other grade 3 non-hematological toxicities such as infection, interstitial lung disease, hyponatremia, hypoglycemia, were observed in 7 patients (24%). No treatment related death was observed. Conclusions: This is the first prospective study of AMR combined with CBDCA for refractory relapsed SCLC, which was effective and well tolerated. Further investigation of this treatment is warranted.

Background: Myxofibrosarcoma is a type of soft-tissue sarcoma that is associated with high rates of local recurrence and distant metastases. The first-line treatment for metastatic soft-tissue sarcoma has conventionally been doxorubicin-based. Recent evidence suggests that myxofibrosarcoma may be molecularly similar to undifferentiated pleomorphic sarcoma (UPS), which is particularly sensitive to gemcitabine-based therapy. The goal of this study was to evaluate the activity of gemcitabine-containing regimens for the treatment of metastatic myxofibrosarcoma refractory to doxorubicin. Material and Methods: We retrospectively evaluated seven consecutive cases of metastatic myxofibrosarcoma at our institution treated with gemcitabine-based therapy in the second-line setting, after progression on doxorubicin. Baseline clinical and baseline characteristics were collected. Primary endpoints were objective response rate (ORR), progression-free survival (PFS) and overall survival (OS). Results: After progression on first-line doxorubicin, a partial, or complete radiological response was observed in four of seven patients who received gemcitabine-based chemotherapy. With a median follow-up of 14 months, median progression-free and overall survival were 8.5 months and 11.4 months, respectively. Conclusions: Gemcitabine-based chemotherapy was associated with encouraging response rates in this cohort, similar to those seen in UPS. Both entities could be studied together for novel gemcitabine-based regimens.

415 Background: Metastatic urothelial carcinoma (mUC) is an aggressive disease with a median overall survival (OS) of ≈ 15 months. In the first-line setting, key prognostic factors include ECOG performance status, white blood cell count, and response to treatment per the Galsky nomogram. Bone metastases (BM) in mUC are associated with morbidity and mortality but are grouped with visceral disease; hence, their impact on prognosis is not well established. We aimed to assess the survival impact of BM in mUC patients treated with first-line platinum-based chemotherapy (PBC). Methods: A retrospective collection of patient and tumor characteristics, with clinical response to treatment (complete response [CR], partial response [PR]; stable disease [SD] or progressive disease [PD]) for patients treated at Princess Margaret Cancer Centre, Tom Baker Cancer Centre, and Cross Cancer Institute from 2005-2018 was performed. Progression-free survival (PFS) and OS were estimated using the Kaplan-Meier method. Univariate (UVA) followed by multivariate analysis (MVA) of patient variables [Cox] using PFS and OS was performed. Results: Overall 376 mUC patients were included; 222 (59%) had soft-tissue metastases (STM) only, 70 (19%) had bone-only metastases, and 84 (22%) had both STM and BM. Overall, 35% had PR or CR, 19% had SD, and 39% had PD (7%: unknown response). The median PFS and OS for the whole cohort were 5.6 months (95%CI: 4.8-6.4) and 9.7 months (95% CI: 8.8-10.8) respectively. Select UVA by metastatic site showed inferior PFS for bone-only (p=0.03) and combination STM and BM (p=0.017). Only combination STM and BM were significant on UVA for OS (p=0.002). MVA showed that bone-only metastases (p=0.03) and ECOG 3-4 (p<0.0001) were associated with worse PFS (Table). Predictors of worse OS were the combination of STM and BM (p=0.02), ECOG 3-4 (p=0.001), and WBCs ≥ULN (p=0.02), (Table). Conclusions: BM are a significant predictor of worse outcomes for mUC patients treated with first-line PBC. Consideration as a treatment stratification factor for future studies is suggested. Strategies for the treatment of mUC patients with BM (ie: bone targeted agents) in the first-line setting should be addressed in future trials. [Table: see text]

Introduction Patients with urothelial carcinoma (uc) have a poor prognosis after progression on first-line cisplatinbased chemotherapy. Real-world data about second-line cytotoxic therapies are limited. We sought to characterize patients with metastatic uc who receive more than 1 line of systemic therapy and to describe their treatments and outcomes.Methods Using BC Cancer’s pharmacy database, we identified patients with documented metastatic uc who had received more than 1 line of systemic therapy. A retrospective chart review was then performed to collect clinicopathologic, treatment, and outcomes data.Results The 51 included patients, of whom 42 were men (82%), had a median age of 65 years (range: 38–81 years). Sites of metastasis included lymph nodes (n = 30), bone (n = 7), lung (n = 9), and peritoneum (n = 2). Second-line chemotherapy regimens included gemcitabine–cisplatin [gc (n = 14)], paclitaxel (n = 24), docetaxel (n = 12), and an oral topoisomerase i inhibitor (n = 1). Median time to progression (ttp) and overall survival (os) were 2.0 and 6.83 months respectively. Compared with patients who received a different agent, patients who had experienced a prior response to first-line gc and who were re-challenged with second-line gc had a better median ttp (11.0 months vs. 6.0 months, p = 0.02) and survived longer (4.0 months vs. 1.0 months, p = 0.02). No differences in os between non-gc regimens were evident.Conclusions In patients with metastatic uc, overall outcomes remain poor, but compared with patients receiving other agents, the subgroup of patients re-challenged with second-line gc demonstrated improved ttp. Conventional chemotherapy regimens provide only modest benefits in the second-line setting and have largely been replaced with immunotherapy.
