Purpose: This study describes oncological outcomes and investigates prognostic factors for patients with gliosarcomas (GSM)., Methods: Histopathologically confirmed GSM patients who underwent treatment at five European institutions were retrospectively analyzed., Results: We analyzed 170 patients with a median clinical follow-up time of 9.2 months. The majority received surgery (94.1%), postoperative radiotherapy (pRT, 81.8%), and temozolomide (TMZ)-based postoperative chemotherapy (66.5%). The median overall survival (OS) and progression-free survival (PFS) were 12.3 and 6.6 months, respectively. In the multivariable Cox regression analysis (MVA), the following factors were significantly associated with OS: age per year (hazard ratio (HR): 1.03, p < 0.001), subtotal resection (STR) versus biopsy only (HR: 0.15, p = 0.018), gross total resection (GTR) versus biopsy only (HR: 0.13, p = 0.011), pRT versus no pRT (HR: 0.20, p < 0.001), postoperative TMZ-based chemotherapy versus no postoperative chemotherapy (HR: 0.44, p = 0.003), MGMT promoter non-methylated versus methylated (HR: 1.79, p = 0.05), and tumor diameter per cm (HR: 1.15, p = 0.046). For PFS, the following factors were significantly associated in the MVA: GTR versus biopsy only (HR: 0.19, p = 0.026), pRT versus no pRT (HR: 0.36, p = 0.006), postoperative TMZ-based chemotherapy vs. no postoperative chemotherapy (HR: 0.39, p < 0.001), MGMT promoter status unknown versus methylated (HR: 1.69, p = 0.034), and tumor diameter per cm (HR: 1.18, p = 0.016). Sex, primary or secondary GSM, and TP53 mutational status were not significantly associated with OS or PFS., Conclusions: Trimodal therapy comprising surgical resection, pRT and TMZ-based chemotherapy appears to have the most beneficial effect on survival in GSM patients. Smaller tumor size, younger age and methylated MGMT promoters are associated with improved survival. To our knowledge, this is the largest multi-institutional cohort study investigating outcomes and prognostic factors for GSM., (© 2024 The Author(s).

Purpose: First-line therapy options in advanced cholangiocarcinoma (CCA) are based on the ABC-02 trial regimen (gemcitabine/cisplatin [G/C]). The NIFE trial examined nanoliposomal irinotecan/fluorouracil/leucovorin (nal-IRI/FU/LV) as alternative first-line therapy in advanced CCA., Methods: NIFE is a prospective, open-label, randomized, multicenter phase II study that aimed at detecting efficacy comparable with the standard treatment. Patients with advanced CCA were randomly assigned (1:1) to receive nal-IRI/FU/LV (arm A) or G/C (arm B). Stratification parameters were intrahepatic versus extrahepatic CCA, sex, and Eastern Cooperative Oncology Group (ECOG; 0/1). Arm A was designed as a Simon's optimal two-stage design and arm B served as a randomized control group. The primary goal was to exclude an inferior progression-free survival (PFS) at 4 months of only 40%, while assuming a rate of 60% on G/C population., Results: Between 2018 and 2020, overall 91 patients were randomly assigned to receive nal-IRI/FU/LV (n = 49) or G/C (n = 42). The NIFE trial formally met its primary end point with a 4-month PFS rate of 51% in patients receiving nal-IRI/FU/LV. The median PFS was 6 months (2.4-9.6) in arm A and 6.9 months (2.5-7.9) in arm B. Median overall survival (OS) was 15.9 months (10.6-20.3) in arm A and 13.6 months (6.5-17.7) in arm B. The exploratory comparison of study arms suggested a numerical but statistically not significant advantage for nal-IRI/FU/LV (hazard ratio for PFS, 0.85 [95% CI, 0.53 to 1.38] and for OS, 0.94 [95% CI, 0.58 to 1.50]). Analysis for stratification parameters revealed no differences for sex and ECOG, but for tumor localization. The objective response rate was 24.5% with nal-IRI/FU/LV and 11.9% with G/C. No unexpected toxicities occurred. AEs related to nal-IRI/FU/LV were mainly GI and to G/C hematologic., Conclusion: Treatment of advanced CCA with nal-IRI/FU/LV demonstrated efficacy in first-line therapy without new safety findings and merits further validation.

Introduction: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is still a rare extralymphatic lymphoma. As of March 1, 2023, approximately 1,355 cases of BIA-ALCL have been reported worldwide. However, no such case has yet been described with pectoral implants in male patients. Most patients with BIA-ALCL present with nonspecific implant-associated symptoms such as late-onset seroma, swollen breasts, and deformation of implants., Case Presentation: Here, we describe BIA-ALCL in a 76-year-old male patient who presented with a late-onset seroma in order to raise awareness for BIA-ALCL also in men after esthetic chest surgery with silicone pectoral implants. The patient had undergone augmentation of the pectoralis muscle with implants for esthetic reasons 9 years before. First cytological specimens showed no malignancy. A repeated cytological assessment after 6 weeks from recurring seroma showed characteristic CD30+ T-cell clones. Surgery with complete bilateral capsulectomy and implant removal was performed. Due to the early-stage ALCL being limited only to the capsule and no evidence of systemic disease, adjuvant systemic treatment was not considered necessary., Conclusion: Any persisting late-onset seroma also in male patients with pectoral implants should raise suspicion of ALCL as differential diagnosis and should be assessed with cytological examination., Competing Interests: Prof. Dr. Eike Burandt: advisory boards for Novartis and Daiichi Sankyo, and speaker’s honoria for AstraZeneca, Eisai, and NOGGO.
