What Is the Impact of Multimodal Treatment in Patients with Leiomyosarcoma of Bone? A Multicenter Study of 35 Patients with an Ultra-Rare Tumor Entity.

Primary leiomyosarcoma of bone (LMSoB) is extremely rare, comprising only <0.7% of primary malignant bone tumors, and is therefore considered an ultra-rare tumor entity. There is currently no consensus as to whether therapeutic strategies should be based on the biological characteristics of soft tissue leiomyosarcoma or on primary tumor localization in the bone. The use of perioperative chemotherapy and its effectiveness in this rare tumor entity remains unclear. We aimed to evaluate the impact of different treatment approaches in a multicenter setting with a total of 35 patients included. The 5-year overall survival (OS) was 74%. Patients with localized disease undergoing surgery had a significantly higher 5-year OS compared to patients who did not undergo surgical treatment (82% vs. 0%, p = 0.0015). Axial tumor localization was associated with worse event-free survival (EFS) probability (p < 0.001) and OS (p = 0.0082). A high proportion of our patients developed secondary metastases. Furthermore, the perioperative chemotherapy protocols applied to our patients were not associated with an improved EFS or OS. Therefore, the benefit of perioperative chemotherapy in LMSoB needs to be further investigated, and the choice of agents still needs to be clarified.

How Do Quality of Life (QoL) and Symptom Burden Evolve in Inpatient Palliative Care (PC) Patients following One Week of Care in a Specialized Palliative Care Unit (PCU)? A Comparison of Two Groups, with One Receiving Specialized Outpatient Palliative Care Prior to Admission.

PURPOSE: This study sought to investigate changes in quality of life (QoL) and symptom burden among palliative care patients undergoing one week of inpatient care in a specialized palliative care unit (PCU). The patient population was stratified into two groups, with one group pretreated from pre-admission palliative care (PC) provided by an outpatient multidisciplinary PC team, while the other group did not receive such support prior to admission. Although the average duration of treatment at a PCU in Germany is 1-2 weeks, the question also arises as to whether a significant improvement in symptom burden and QoL can be expected after just one week of PC in a PCU. METHODS: PC patients with various cancer entities were prospectively included in a non-randomized study. Patients in group 1 received outpatient specialized PC prior to admission, while patients in group 2 did not. Over an 8-month period, we gathered data from one academic cancer center, utilizing the EORTC QLQ-C30, one of the most widely used patient-reported outcome (PRO) instruments to assess health-related QoL in cancer patients. Patients completed the QLQ-C30 at T0 (admission or one day later) and T1 (one week later), enabling the assessment of potential changes in their QoL and symptom burden over time. RESULTS: A total of 103 patients (51.5% male) were enrolled (group 1: 42%, group 2: 58%). At T0, there were no significant differences regarding QLQ-C30 scores between groups 1 and 2, except from global health/QoL (group 1 mean 20.7, group 2 mean 25.6, p = 0.026). Over the course of one week several significant and clinically relevant changes were found: Emotional functioning demonstrated an uplift in both groups (group 1: mean 41.5 IQR 33 vs. 53.1 IQR 50, p = 0.014, group 2: mean 48.2 IQR 46 vs. 56.8 IQR 58, p = 0.029), as did the global health status (group 1: M 20.7 IQR 17 vs. 36.2 IQR 33, p < 0.001, group 2: M 25.6 IQR 25 vs. 35.3 IQR 33, p < 0.001). Nausea and vomiting showed a reduction (group 1: M 29.9 IQR 17 vs. 6.8 IQR 0, p < 0.001, group 2: M 22.6 IQR 17 vs. 8.2 IQR 0, p < 0.001), along with a notable decline in pain (group 1: M 67.4 IQR 67 vs. 25.3 IQR 17, p < 0.001, group 2: M 73.1 IQR 83 vs. 29.7 IQR 17, p < 0.001). A decrease was observed in insomnia (group 1: M 63.6 IQR 67 vs. 27.6 IQR 33, p < 0.001, group 2: M 60.1 IQR 67 vs. 27.6 IQR 33, p < 0.001). There were no significant differences between groups 1 and 2 in the extent of improvement in the various symptom scales from T0 to T1. CONCLUSION: The findings of our study demonstrate that QoL and several symptoms prevalent in cancer patients cared for in the PCU experienced significant enhancement over the span of just one week. Both groups, patients receiving specialized outpatient PC prior to admission and those without, equally benefited from inpatient PC. All mentioned changes from T0 to T1 are considered not only significant but clinically relevant.

Regional hyperthermia for soft tissue sarcoma - a survey on current practice, controversies and consensus among 12 European centers.

PURPOSE: To analyze the current practice of regional hyperthermia (RHT) for soft tissue sarcoma (STS) at 12 European centers to provide an overview, find consensuses and identify controversies necessary for future guidelines and clinical trials. METHODS: In this cross-sectional survey study, a 27-item questionnaire assessing clinical subjects and procedural details on RHT for STS was distributed to 12 European cancer centers for RHT. RESULTS: We have identified seven controversies and five consensus points. Of 12 centers, 6 offer both, RHT with chemotherapy (CTX) or with radiotherapy (RT). Two centers only offer RHT with CTX and four centers only offer RHT with RT. All 12 centers apply RHT for localized, high-risk STS of the extremities, trunk wall and retroperitoneum. However, eight centers also use RHT in metastatic STS, five in palliative STS, eight for superficial STS and six for low-grade STS. Pretherapeutic imaging for RHT treatment planning is used by 10 centers, 9 centers set 40-43 °C as the intratumoral target temperature, and all centers use skin detectors or probes in body orifices for thermometry. DISCUSSION: There is disagreement regarding the integration of RHT in contemporary interdisciplinary care of STS patients. Many clinical controversies exist that require a standardized consensus guideline and innovative study ideas. At the same time, our data has shown that existing guidelines and decades of experience with the technique of RHT have mostly standardized procedural aspects. CONCLUSIONS: The provided results may serve as a basis for future guidelines and inform future clinical trials for RHT in STS patients.

Efficacy of ramucirumab combination chemotherapy as second-line treatment in patients with advanced adenocarcinoma of the stomach or gastroesophageal junction after exposure to checkpoint inhibitors and chemotherapy as first-line therapy.

FOLFOX plus nivolumab represents a standard of care for first-line therapy of advanced gastroesophageal cancer (aGEC) with positive PD-L1 expression. The efficacy of second-line VEGFR-2 inhibition with ramucirumab (RAM) plus chemotherapy after progression to immunochemotherapy remains unclear. Medical records of patients with aGEC enrolled in the randomized phase II AIO-STO-0417 trial after treatment failure to first-line FOLFOX plus nivolumab and ipilimumab were retrospectively analyzed. Patients were divided into two groups based on second-line therapy: RAM plus chemotherapy (RAM group) or treatment without RAM (control group). Eighty three patients were included. In the overall population, progression-free survival (PFS) in the RAM group was superior to the control (4.5 vs 2.9 months). Responders (CR/PR) to first-line immunochemotherapy receiving RAM containing second-line therapy had prolonged OS from start of first-line therapy (28.9 vs 16.5 months), as well as second-line OS (9.6 vs 7.5 months), PFS (5.6 vs 2.9 months) and DCR (53% vs 29%) compared to the control. PD-L1 CPS ≥1 was 42% and 44% for the RAM and the control, respectively. Patients with CPS ≥1 in the RAM group showed better tumor control (ORR 25% vs 10%) and improved survival (total OS 11.5 vs 8.0 months; second-line OS 6.5 vs 3.9 months; PFS 4.5 vs 1.6 months) compared to the control. Prior exposure to first-line FOLFOX plus dual checkpoint inhibition followed by RAM plus chemotherapy shows favorable response and survival rates especially in patients with initial response and positive PD-L1 expression and has the potential to advance the treatment paradigm in aGEC.

Geriatric Assessment of Older Patients Receiving Trabectedin in First-Line Treatment for Advanced Soft Tissue Sarcomas: The E-TRAB Study from The German Interdisciplinary Sarcoma Group (GISG-13).

E-TRAB was a non-interventional, prospective trial investigating the feasibility and predictive value of geriatric assessments (GA) in older STS patients treated with trabectedin as first-line therapy. Primary endpoints were overall survival (OS), quality of life and individual clinical benefit assessed by the patient-reported outcome measures QLQ-C30 and PRO-CTCAE. Further, several GA tools were applied and correlated with clinical outcomes and treatment-related toxicities. The final analyses included 69 patients from 12 German-speaking sites. The median age of patients was 78 years (range: 55 to 88). Baseline data on PROs and GA identified a diverse population of older patients with respect to their global health status, although a large proportion of them suffered from limitations, required geriatric help and had a high risk of morbidity. The Cancer and Age Research Group (CARG) score classified 38%, 29% and 23% of the patients with low, intermediate and high risks for therapy-related side effects, respectively. Median OS was 11.2 months [95%CI: 5.6; 19.4]. The study confirmed that trabectedin as first-line treatment in older patients with STS has an acceptable and manageable safety profile. Potential prognostic factors for clinical outcome and therapy-related toxicity were identified among the GA tools. Long Timed Up and Go (TUG) showed a significant correlation to OS and early death, whereas a high CARG score (>9) was associated with an increase in unplanned hospitalizations and the incidence of toxicities grade ≥ 3.

Ramucirumab, Avelumab, and Paclitaxel as Second-Line Treatment in Esophagogastric Adenocarcinoma: The Phase 2 RAP (AIO-STO-0218) Nonrandomized Controlled Trial.

Importance: Adding immune checkpoint inhibitors to chemotherapy has been associated with improved outcomes in metastatic esophagogastric adenocarcinoma, but treatment combinations and optimal patient selection need to be established. Objective: To investigate the efficacy and tolerability of the programmed cell death ligand 1 (PDL-1) inhibitor avelumab with paclitaxel plus ramucirumab. Design, Setting, and Participants: This multicenter, single-group, phase 2 nonrandomized controlled trial was conducted among patients with second-line metastatic esophagogastric adenocarcinoma. Patients pretreated with platinum plus fluoropyrimidine between April 2019 and November 2020 across 10 German centers (median follow-up, 27.4 months [95% CI 22.0-32.9 months]) were included. Data analysis was performed from January to December 2022. Interventions: Patients received ramucirumab at 8 mg/kg on days 1 and 15, avelumab at 10 mg/kg on days 1 and 15, and paclitaxel at 80 mg/m2 on days 1, 8, and 15 every 4 weeks. Main Outcomes and Measures: The prespecified primary end point was overall survival (OS) rate at 6 months, with the experimental therapy considered insufficiently active with an OS rate of 50% or less and a promising candidate with an OS rate of 65% or greater. Results: Of 60 enrolled patients, 59 patients (median [range] age, 64 [18-81] years; 47 males [70.7%]) were evaluable, including 30 patients with metastatic adenocarcinoma of the stomach and 29 patients with gastroesophageal junction. All patients were pretreated with platinum plus fluoropyrimidine, and 40 patients (67.8%) had received prior taxanes; 24 of 56 evaluable patients (42.9%) had a PDL-1 combined positive score (CPS) of 5 or greater, centrally assessed. The OS rate at 6 months was 71.2% (95% CI, 61.5%-83.7%). The median OS in the intention-to-treat population (59 patients) was 10.6 months (95% CI, 8.4-12.8 months) overall. Among patients assessable by central pathology, median OS was 9.4 months (95% CI, 7.2-11.7 months) in 32 patients with a PDL-1 CPS less than 5 and 14.0 months (95% CI, 6.0-22.1 months) in 24 patients with a PDL-1 CPS of 5 or greater (P = .25). Treatment was generally well tolerated, without unexpected toxicities. Patients with higher vs lower than median T cell repertoire richness showed an increased median OS of 20.4 months (95% CI, 7.7-33.0 months) compared with 8.3 months (95% CI, 3.7-12.9 months; hazard ratio, 0.43; 95% CI, 0.23-0.81; P = .008). Patients with lower vs higher than median cell-free DNA burden had a median OS of 19.2 months (95% CI, 8.9-29.6 months) compared with 7.3 months (95% CI, 3.2-11.4 months; hazard ratio, 0.30; 95% CI, 0.16-0.59; P < .001). Conclusions and relevance: In this study, the combination of avelumab with paclitaxel plus ramucirumab showed favorable efficacy and tolerability in the second-line treatment for metastatic esophagogastric adenocarcinoma. A PDL-1 CPS score of 5 or greater, cell-free DNA level less than the median, and T cell repertoire richness greater than the median were associated with increased median OS.

Health related Quality of Life over time in German sarcoma patients. An analysis of associated factors - results of the PROSa study.

Introduction: Sarcomas are rare cancers and very heterogeneous in their location, histological subtype, and treatment. Health-Related Quality of Life (HRQoL) of sarcoma patients has rarely been investigated in longitudinal studies. Methods: Here, we assessed adult sarcoma patients and survivors between September 2017 and February 2020, and followed-up for one year in 39 study centers in Germany. Follow-up time points were 6 (t1) and 12 months (t2) after inclusion. We used a standardized, validated questionnaire (the European Organisation for Research and Treatment of Cancer Quality of Life Core Instrument (EORTC QLQ-C30) and explored predictors of HRQoL in two populations (all patients (Analysis 1), patients in ongoing complete remission (Analysis 2)) using generalized linear mixed models. Results: In total we included up to 1111 patients at baseline (915 at t1, and 847 at t2), thereof 387 participants were in complete remission at baseline (334 at t1, and 200 at t2). When analyzing all patients, HRQoL differed with regard to tumor locations: patients with sarcoma in lower extremities reported lower HRQoL values than patients with sarcomas in the upper extremities. Treatment which included radiotherapy and/or systemic therapy was associated with lower HRQoL. For patients in complete remission, smoking was associated with worse HRQoL-outcomes. In both analyses, bone sarcomas were associated with the worst HRQoL values. Being female, in the age group 55-<65 years, having lower socioeconomic status, and comorbidities were all associated with a lower HRQoL, in both analyses. Discussion: HRQoL increased partially over time since treatment and with sporting activities. HRQoL improved with time since treatment, although not in all domains, and was associated with lifestyle and socioeconomic factors. Bone sarcomas were the most affected subgroup. Methods to preserve and improve HRQoL should be developed for sarcoma patients.

Evaluation of electronic patient-reported outcome assessment in inpatient cancer care: a feasibility study.

PURPOSE: Patient-reported outcome (PRO) measures are increasingly important in evaluating medical care. The increased integration of technology within the healthcare systems allows for collection of PROs electronically. The objectives of this study were to Ashley et al. J Med Internet Res (2013) implement an electronic assessment of PROs in inpatient cancer care and test its feasibility for patients and Dawson et al. BMJ (2010) determine the equivalence of the paper and electronic assessment. METHODS: We analyzed two arms from a study that was originally designed to be an interventional, three-arm, and multicenter inpatient trial. A self-administered questionnaire based on validated PRO-measures was applied and completed at admission, 1 week after, and at discharge. For this analysis - focusing on feasibility of the electronic assessment - the following groups will be considered: Group A (intervention arm) received a tablet version, while group B (control arm) completed the questionnaire on paper. A feasibility questionnaire, that was adapted from Ashley et al. J Med Internet Res (2013), was administered to group A. RESULTS: We analyzed 103 patients that were recruited in oncology wards. ePRO was feasible to most patients, with 84% preferring the electronic over paper-based assessment. The feasibility questionnaire contained questions that were answered on a scale ranging from "1" (illustrating non achievement) to "5" (illustrating achieving goal). The majority (mean 4.24, SD .99) reported no difficulties handling the electronic tool and found it relatively easy finding time for filling out the questionnaire (mean 4.15, SD 1.05). There were no significant differences between the paper and the electronic assessment regarding the PROs. CONCLUSION: Results indicate that electronic PRO assessment in inpatient cancer care is feasible.

Hyperthermia in the treatment of high-risk soft tissue sarcomas: a systematic review.

BACKGROUND: The therapy of high-risk soft tissue sarcomas (STS) remains an interdisciplinary challenge. Regional hyperthermia (RHT) sparked interest as it has been shown to improve overall survival when added to perioperative chemotherapy (CTX). However, questions arise on how RHT should be optimally integrated into current multi-modal therapies. MATERIALS AND METHODS: We performed a systematic literature review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies written in English and focused mainly on radiative RHT and superficial hyperthermia were evaluated and included. Studies including patients below the age of 18, with metastatic disease or review articles, were excluded. RESULTS: We identified 15 clinical reports from 1990 until July 2022. Three articles combined RHT + CTX, and twelve focused on combined RHT + radiotherapy (RT) or neoadjuvant chemoradiotherapy (CRT). Most treatments were based on invasive thermometry, and less on magnetic resonance imaging (MRI)-based, noninvasive thermometry for STS of the extremities. Perioperative chemotherapy was used for the combination of RHT and CTX, mostly Ifosfamide-based. The effectiveness of RT appeared to be increased by RHT, especially with two RHT sessions/week. The trimodal simultaneous approach of neoadjuvant RHT and CRT was also feasible. No significant toxicity of RHT was reported. CONCLUSIONS: The gathered data strengthen the beneficial role of RHT in the multimodal setting. Further expert consensus and clinical trials are required to determine the optimal integration of RHT in treating STS.

Ramucirumab plus irinotecan / leucovorin / 5-FU versus ramucirumab plus paclitaxel in patients with advanced or metastatic adenocarcinoma of the stomach or gastroesophageal junction, who failed one prior line of palliative chemotherapy: the phase II/III RAMIRIS study (AIO-STO-0415).

BACKGROUND: Paclitaxel in combination with ramucirumab is the standard of care second-line therapy in gastro-esophageal adenocarcinoma (GEA). As the number of taxane pretreated patients in the perioperative or first-line setting is increasing, it is unknown whether these patients benefit from re-applying a taxane in using the combination of paclitaxel and ramucirumab. Furthermore, the rates of neurotoxicity with first-line FOLFOX or FLOT range from 30%-70%, making second-line taxane-containing therapy less suitable to a meaningful portion of patients. This patient group is likely to benefit from a taxane-free second-line chemotherapy regimen, such as FOLFIRI and ramucirumab (FOLFIRI-Ram). Therefore, the RAMIRIS phase III trial evaluates the effects of the regimen of FOLFIRI-Ram in the second-line treatment after a taxane-based chemotherapy in patients with advanced GEA. METHODS: The RAMIRIS trial is a randomized, open-label, multicenter phase II/III study comparing treatment of FOLFIRI-Ram (arm A) with paclitaxel and ramucirumab (arm B). The Phase II is already closed with 111 enrolled patients. In the phase III, 318 taxane-pretreated patients with advanced GEA will be recruited and randomized 1:1 to FOLFIRI (5-FU 2400 mg/m2 over 46 h i.v., irinotecan 180 mg/m2 i.v.; 5-FU 400 mg/m2 bolus; leucovorin 400 mg/m2 i.v.; on day 1 and 15, q28) with ramucirumab 8 mg/kg every two weeks (Arm A) or paclitaxel 80 mg/m2 (days 1, 8, 15, q28) with ramucirumab 8 mg/kg every two weeks (Arm B). The primary endpoints are overall survival (OS) and objective overall response rate (ORR). Secondary endpoints are progression-free survival (PFS), disease control rate and safety and quality of life as assessed by EORTC-QLQ-C30 questionnaire. DISCUSSION: The already completed RAMIRIS phase II demonstrated feasibility and efficacy of FOLFIRI-Ram. Especially docetaxel-pretreated patients seemed to markedly benefit from FOLFIRI-Ram, with favorable response- and PFS rates and lower toxicity. This offers a rationale for the phase III trial. If the RAMIRIS III trial transfers and confirms the results, they will affect the current treatment guidelines, recommending the combination therapy of FOLFIRI-Ram for taxane-pretreated patients with advanced GEA. TRIAL REGISTRATION: NCT03081143 Date of registration: 13.11.2015.

Perioperative FLOT plus ramucirumab for resectable esophagogastric adenocarcinoma: A randomized phase II/III trial of the German AIO and Italian GOIM.

This multicenter, randomized phase II/III study evaluated the addition of the vascular endothelial growth factor receptor-2 inhibitor ramucirumab to FLOT as perioperative treatment for resectable esophagogastric adenocarcinoma. Patients received either FLOT alone (Arm A) or combined with ramucirumab followed by ramucirumab monotherapy (Arm B). The primary endpoint for the phase II portion was the pathological complete or subtotal response (pCR/pSR) rate. Baseline characteristics were comparable between both arms with a high rate of tumors signet-ring cell component (A:47% B:43%). No between-arm difference in pCR/pSR rate was seen (A:29% B:26%), therefore the transition to phase III was not pursued. Nevertheless, the combination was associated with a significantly increased R0-resection rate compared with FLOT alone (A:82% B:96%; P = .009). In addition, the median disease-free survival was numerically improved in Arm B (A:21 months B:32 months, HR 0.75, P = 0.218), while the median overall survival was similar in both treatment arms (A:45 months B:46 months, HR 0.94, P = 0.803). Patients with Siewert type I tumors receiving transthoracic esophagectomy with intrathoracic anastomosis showed an increased risk of serious postoperative complications after ramucirumab treatment, therefore recruitment of those patients was stopped after the first-third of the study. Overall, surgical morbidity and mortality was comparable, whereas more non-surgical grade ≥ 3 adverse events were observed with the combination, especially anorexia (A:1% B:11%), hypertension (A:4% B:13%) and infections (A:19% B:33%). The combination of ramucirumab and FLOT as perioperative treatment shows efficacy signals, particularly in terms of R0 resection rates, for a study population with a high proportion of prognostically poor histological subtypes, and further evaluation in this subgroup seems warranted.

Working situation and burden of work limitations in sarcoma patients: results from the multi-center prospective PROSa study.

PURPOSE: We investigated predictors of limitations in work performance, odds of drop out of work, and odds of receiving disability pension in sarcoma patients. METHODS: We measured clinical and sociodemographic data in adult sarcoma patients and recorded if the patients received a (1) disability pension at baseline or (2) had dropped out of work 1 year after initial assessment. (3) Work limitations were assessed using the Work-limitations questionnaire (WLQ©). We analyzed exploratively. RESULTS: (1) Amongst 364 analyzed patients, odds to receive a disability pension were higher in patients with abdominal tumors, older patients, high grade patients and with increasing time since diagnosis. (2) Of 356 patients employed at baseline, 21% (n = 76) had dropped out of work after 1 year. The odds of dropping out of work were higher in bone sarcoma patients and in patients who received additive radiotherapy ± systemic therapy compared with patients who received surgery alone. Odds of dropping out of work were less amongst self-employed patients and dropped with increasing time since diagnosis. (3) Work limitations were higher in woman and increased with age. Patients with bone and fibrous sarcomas were more affected than liposarcoma patients. Patients with abdominal tumors reported highest restrictions. Sarcoma treatment in the last 6 months increased work limitations. CONCLUSION: Work limitations, drop out of work and dependence on a disability pension occurs frequently in patients with sarcoma adding to the burden of this condition. We were able to identify vulnerable groups in both the socioeconomic and disease categories.

Trabectedin for Patients with Advanced Soft Tissue Sarcoma: A Non-Interventional, Prospective, Multicenter, Phase IV Trial.

This non-interventional, prospective phase IV trial evaluated trabectedin in patients with soft tissue sarcoma (STS) in real-life clinical practice across Germany. The primary endpoints were progression-free survival (PFS) rates at 3 and 6 months, as defined by investigators. Overall, 128 patients from 19 German sites were evaluated for efficacy and 130 for safety. Median age was 58.5 years (range: 23-84) and leiomyosarcoma was the most frequent histotype (n = 45; 35.2%). Trabectedin was mostly used as second/third-line treatment (n = 91; 71.1%). Median PFS was 5.2 months (95% CI: 3.3-6.7), with 60.7% and 44.5% of patients free from progression at 3 and 6 months, respectively. Median overall survival was 15.2 months (95% CI: 9.6-21.4). One patient achieved a complete and 14 patients a partial response, conferring an objective response rate of 11.7%. Decreases in white blood cells (27.0% of patients), platelets (16.2%) and neutrophils (13.1%) and increased alanine aminotransferase (10.8%) were the most common trabectedin-related grade 3/4 adverse drug reactions. Two deaths due to pneumonia and sepsis were considered trabectedin-related. Trabectedin confers clinically meaningful activity in patients with multiple STS histotypes, comparable to that previously observed in clinical trials and other non-interventional studies, and with a manageable safety profile.

Distress in soft-tissue sarcoma and gastrointestinal stromal tumours patients-Results of a German multicentre observational study (PROSa).

OBJECTIVE: Soft tissue sarcomas (STS) and gastrointestinal stromal tumours (GIST) are a group of rare malignant tumours with a high and heterogenous disease burden. As evidence is scarce, we analysed the prevalence of increased emotional distress and identified distress-associated factors in these patients. METHODS: The PROSa-study (Burden and medical care of sarcoma) was conducted between 2017 and 2020 in 39 study centres. Cross-sectional data from adult STS and GIST patients were analysed. Distress was measured with the Patient Health Questionnaire (PHQ-4). The relation of socioeconomic and clinical factors with distress was explored in adjusted logistic regression models. RESULTS: Among 897 patients, 17% reported elevated anxiety and 19% reported depression. Unemployed patients (odds ratio [OR] 6.6; 95% CI 2.9-15.0), and those with a disability pension (OR 3.1; 95% CI 1.9-5.0) were more likely to experience distress compared to employed patients. Also, patients with a disability pass had higher odds of increased distress than those without (OR 1.8; 95% CI 1.2-2.7). Lowest distress was observed in patients 2 to <5 years and ≥5 years after diagnosis (comparison: <6 months) (OR 0.4; 95% CI 0.2-0.6) and (0.3; 95% CI 0.2-0.6). Patients with thoracic STS (vs. lower limbs) had twice the odds to experience distress (OR 2.0; 95% CI 1.1-3.6). Distress was seen almost twice as often in patients with progressive disease (vs. complete remission) (OR 1.7; 95% CI 1.1-2.8). CONCLUSION: The prevalence of elevated distress in STS and GIST patients is high. In unemployed patients, in those with a disability pension and in newly diagnosed patients a noticeable increase was observed. Clinicians should be aware of these factors and consider the social aspects of the disease.

Transferability of Health-Related Quality of Life Data of Large Observational Studies to Clinical Practice: Comparing Retroperitoneal Sarcoma Patients from the PROSa Study to a TARPS-WG Cohort.

INTRODUCTION: Health-related quality of life (HRQoL) is crucial for shared decision-making. The "Patient-Reported Outcome measures in Sarcoma" (PROSa) study evaluated HRQoL in general. We evaluated the transferability of PROSa data to clinical practice for the subgroup of retroperitoneal sarcoma (RPS). METHODS: To obtain a PROSa-RPS cohort, we excluded patients with bone sarcomas and gastrointestinal stromal tumors from the complete PROSa cohort (n = 1,113), limited tumor localization to trunk and retroperitoneum, and excluded patients with metastases. We evaluated the HRQoL data of the resulting 76 patients and compared their clinical data to those of the Transatlantic Autralasian Retroperitoneal Sarcoma Working Group (TARPS-WG, n = 1,007). RESULTS: Confidence intervals for patient sex, histological subtype (LPS vs. non-LPS), grading (G1 vs. G2/3), surgical margins (R2 vs. no R2), and perioperative chemo- and radiotherapy (yes vs. no) were overlapping in both cohorts. EORTC QLQ-C30 from RPS-PROSa patients demonstrated that two-thirds had clinically relevant restrictions in physical functioning. Two-thirds reported dyspnea, followed by fatigue and pain. CONCLUSION: Clinical data from RPS-PROSa patients are comparable to those of an RPS reference cohort from expert centers. We believe that HRQoL data of RPS patients extracted from PROSa are transferable to clinical practice.

FLOT Versus FLOT/Trastuzumab/Pertuzumab Perioperative Therapy of Human Epidermal Growth Factor Receptor 2-Positive Resectable Esophagogastric Adenocarcinoma: A Randomized Phase II Trial of the AIO EGA Study Group.

PURPOSE: High pathologic complete response (pCR) rates and comparably good survival data were seen in a phase II trial combining perioperative fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy with trastuzumab for resectable, esophagogastric adenocarcinoma (EGA). The current trial evaluates the addition of trastuzumab and pertuzumab to FLOT as perioperative treatment for human epidermal growth factor receptor 2-positive resectable EGA. METHODS: In this multicenter, randomized phase II/III trial, patients with human epidermal growth factor receptor 2-positive, resectable EGA (≥ clinical tumor 2 or clinical nodal-positive) were assigned to four pre- and postoperative cycles of either FLOT alone (arm A) or combined with trastuzumab and pertuzumab, followed by nine cycles of trastuzumab/pertuzumab (arm B). The primary end point for the phase II part was the rate of pCR. RESULTS: The trial was closed prematurely, without transition into phase III, after results of the JACOB trial were reported. Eighty-one patients were randomly assigned (A: 41/B: 40) during the phase II part. The pCR rate was significantly improved with the trastuzumab/pertuzumab treatment (A: 12%/B: 35%; P = .02). Similarly, the rate of pathologic lymph node negativity was higher with trastuzumab/pertuzumab (A: 39%/B: 68%), whereas the R0 resection rate (A: 90%/B: 93%) and surgical morbidity (A: 43%/B: 44%) were comparable. Moreover, the inhouse mortality was equal in both arms (overall 2.5%). The median disease-free survival was 26 months in arm A and not yet reached in arm B (hazard ratio, 0.58; P = .14). After a median follow-up of 22 months, the median overall survival was not yet reached (hazard ratio, 0.56; P = .24). Disease-free survival and overall survival rates at 24 months were 54% (95% CI, 38 to 71) and 77% (95% CI, 63 to 90) in arm A and 70% (95% CI, 55 to 85) and 84% (95% CI, 72 to 96) in arm B, respectively. More ≥ grade 3 adverse events were reported with trastuzumab/pertuzumab, especially diarrhea (A: 5%/B: 41%) and leukopenia (A: 13%/B: 23%). CONCLUSION: The addition of trastuzumab/pertuzumab to perioperative FLOT significantly improved pCR and nodal negativity rates at the price of higher rates of diarrhea and leukopenia.

Efficacy of Ipilimumab vs FOLFOX in Combination With Nivolumab and Trastuzumab in Patients With Previously Untreated ERBB2-Positive Esophagogastric Adenocarcinoma: The AIO INTEGA Randomized Clinical Trial.

Importance: In metastatic esophagogastric adenocarcinoma (EGA), the addition of programmed cell death 1 (PD-1) inhibitors to chemotherapy has improved outcomes in selected patient populations. Objective: To investigate the efficacy of trastuzumab and PD-1 inhibitors with cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitors or FOLFOX in first-line treatment of advanced ERBB2-positive EGA. Design, Setting, and Participants: This phase 2 multicenter, outpatient, randomized clinical trial with 2 experimental arms compared with historical control individually was conducted between March 2018 and May 2020 across 21 German sites. The reported results are based on a median follow-up of 14.3 months. Patients with previously untreated, metastatic ERBB2-positive (local immunohistochemistry score of 3+ or 2+/in situ hybridization amplification positive) EGA, adequate organ function, and eligibility for immunotherapy were included. Data analysis was performed from June to September 2021. Interventions: Patients were randomized to trastuzumab and nivolumab (1 mg/kg × 4/240 mg for up to 12 months) in combination with mFOLFOX6 (FOLFOX arm) or ipilimumab (3 mg/kg × 4 for up to 12 weeks) (ipilimumab arm). Main Outcomes and Measures: The primary end point was survival improvement with a targeted increase of the 12-month overall survival rate from 55% (trastuzumab/chemotherapy-ToGA regimen) to 70% in each arm. Results: A total of 97 patients were enrolled, and 88 were randomized (18 women, 70 men; median [range] age, 61 [41-80] years). Baseline Eastern Cooperative Oncology Group performance status was 0 in 54 patients (61%) and 1 in 34 patients (39%); 66 patients (75%) had EGA localized in the esophagogastric junction and 22 in the stomach (25%). Central post hoc biomarker analysis (84 patients) showed PD-1 ligand 1 (PD-L1) combined positive score of 1 or greater in 59 patients (72%) and 5 or greater in 46 patients (56%) and confirmed ERBB2 positivity in 76 patients. The observed overall survival rate at 12 months was 70% (95% CI, 54%-81%) with FOLFOX and 57% (95% CI, 41%-71%) with ipilimumab. Treatment-related grade 3 or greater adverse events (AEs) and serious AEs occurred in 29 and 15 patients in the FOLFOX arm and in 20 and 17 patients in the ipilimumab arm, respectively, with a higher incidence of autoimmune-related AEs in the ipilimumab arm and neuropathy in the FOLFOX arm. Liquid biopsy analyses showed strong correlation of early cell-free DNA increase with shorter progression-free and overall survival and emergence of truncating and epitope-loss ERBB2 resistance sequence variations with trastuzumab treatment. Conclusions and Relevance: In this randomized clinical trial, trastuzumab, nivolumab, and FOLFOX showed favorable efficacy compared with historical data and trastuzumab, nivolumab, and ipilimumab in ERBB2-positive EGA. The ipilimumab arm yielded similar OS compared with the ToGA regimen. Trial Registration: ClinicalTrials.gov Identifier: NCT03409848.

FOLFIRI plus ramucirumab versus paclitaxel plus ramucirumab as second-line therapy for patients with advanced or metastatic gastroesophageal adenocarcinoma with or without prior docetaxel - results from the phase II RAMIRIS Study of the German Gastric Cancer Study Group at AIO.

BACKGROUND: Ramucirumab and paclitaxel is the standard second-line therapy in patients with metastatic gastroesophageal adenocarcinoma. We report the efficacy and safety analyses of FOLFIRI and ramucirumab versus paclitaxel and ramucirumab after the failure of a platinum- and fluoropyrimidine-containing chemotherapy. METHODS: This multicenter, investigator initiated, phase II trial randomised patients with gastroesophageal adenocarcinoma to either FOLFIRI plus ramucirumab (RAM) (arm A) or paclitaxel plus RAM (arm B). The primary end-point was 6-month overall survival (OS) rate, with a proportion of ≥65% in arm A considered a positive signal for further investigation. RESULTS: 111 patients (65% of patients had prior docetaxel) were enrolled and 110 patients qualified for ITT population (arm A, 72; arm B, 38). The study did not meet the primary end-point for the comparison with historical control, as 6-month OS rate in the FOLFIRI plus RAM arm was 54% (95% CI 44-67). In between arm comparison, OS was similar (hazard ratio, HR 0.97 [95% CI 0.62-1.52]), while objective response rates (ORRs) and PFS were numerically better in arm A versus arm B (HR for PFS 0.73; ORR, 22% versus 11%). These differences were largely attributed to favourable efficacy results for arm A in docetaxel-pretreated patients (HR, 0.49; ORR, 25% versus 8%). In the safety population (n = 106), grade 3-5 adverse events were similar between arms (arm A, 75%; arm B, 68%). CONCLUSION: The RAMIRIS trial demonstrated feasibility of FOLFIRI plus RAM. While the study was formally negative, it provided a signal to further investigate this combination for the group of patients with previous docetaxel therapy.

The association of Health-Related Quality of Life and 1-year-survival in sarcoma patients-results of a Nationwide Observational Study (PROSa).

BACKGROUND: Sarcomas are rare cancers of high heterogeneity. Health-Related Quality of Life (HRQoL) has been shown to be a prognostic factor for survival in other cancer entities but it is unclear whether this applies to sarcoma patients. PATIENTS AND METHODS: HRQoL was prospectively assessed in adult sarcoma patients from 2017 to 2020 in 39 German recruiting sites using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Vital status was ascertained over the course of 1 year. HRQoL domains were analysed by multivariable cox-regressions including clinical and socio-economic risk factors. RESULTS: Of 1102 patients, 126 (11.4%) died during follow-up. The hazard ratio (HR) for global health was 0.73 per 10-point increase (95% confidence interval (CI) 0.64-0.85). HR for the HRQoL-summary score was 0.74 (CI 0.64-0.85) and for physical functioning 0.82 (CI 0.74-0.89). There was also evidence that fatigue (HR 1.17, CI 1.10-1.25), appetite loss (HR 1.15, CI 1.09-1.21) and pain (HR 1.14, CI 1.08-1.20) are prognostic factors for survival. CONCLUSION: Our study adds sarcoma-specific evidence to the existing data about cancer survival in general. Clinicians and care-givers should be aware of the relations between HRQoL and survival probability and include HRQoL in routine assessment.

Financial toxicity in sarcoma patients and survivors in Germany: results from the multicenter PROSa study.

PURPOSE: Cancer patients have been shown to frequently suffer from financial burden before, during, and after treatment. However, the financial toxicity of patients with sarcoma has seldom been assessed. Therefore, the aim of this study was to evaluate whether financial toxicity is a problem for sarcoma patients in Germany and identify associated risk factors. METHODS: Patients for this analysis were obtained from a multicenter prospective cohort study conducted in Germany. Using the financial difficulties scale of the EORTC QLQ-C30, financial toxicity was considered to be present if the score exceeded a pre-defined threshold for clinical importance. Comparisons to an age- and sex-matched norm population were performed. A multivariate logistic regression using stepwise backward selection was used to identify factors associated with financial toxicity. RESULTS: We included 1103 sarcoma patients treated in 39 centers and clinics; 498 (44.7%) patients reported financial toxicity. Sarcoma patients had 2.5 times the odds of reporting financial difficulties compared to an age- and sex-matched norm population. Patient age < 40 and > 52.5 years, higher education status, higher income, and disease progression (compared to patients with complete remission) were associated with lower odds of reporting financial toxicity. Receiving a disability pension, being currently on sick leave, and having a disability pass were statistically significantly associated with higher odds of reporting financial toxicity. CONCLUSION: Financial toxicity is present in about half of German sarcoma patients, making it a relevant quality of life topic for patients and decision-makers.
