Assessing the Safety and Efficacy of Two Starting Doses of Lenvatinib Plus Everolimus in Patients with Renal Cell Carcinoma : A Randomized Phase 2 Trial

Background: Lenvatinib (18 mg) plus everolimus (5 mg) is approved for patients with advanced renal cell carcinoma (RCC) after one or more prior antiangiogenic therapies. Objective: To assess whether a lower starting dose of lenvatinib has comparable efficacy with improved tolerability for patients with advanced RCC treated with lenvatinib plus everolimus. Design, setting, and participants: A randomized, open-label, phase 2 global trial was conducted in patients with advanced clear cell RCC and disease progression after one prior vascular endothelial growth factor–targeted therapy (prior anti–programmed death-1/programmed death ligand-1 therapy permitted). Intervention: Patients were randomly assigned 1:1 to the 14- or 18-mg lenvatinib starting dose, both in combination with everolimus 5 mg/d. Patients in the 14-mg arm were to be uptitrated to lenvatinib 18 mg at cycle 2, day 1, barring intolerable grade 2 or any grade ≥3 treatment-emergent adverse events (TEAEs) requiring dose reduction occurring in the first 28-d cycle. Outcome measurements and statistical analysis: The primary efficacy endpoint was investigator-assessed objective response rate (ORR) as of week 24 (ORRwk24); the noninferiority threshold of the 14- versus 18-mg arm was p ≤ 0.045. The primary safety endpoint was the proportion of patients with intolerable grade 2 or any grade ≥3 TEAEs within 24 wk of randomization. Results and limitations: The ORRwk24 for the 14-mg arm (32% [95% confidence interval {CI} 25–39]) was not noninferior to the ORRwk24 in the 18-mg arm (35% [95% CI 27–42]; odds ratio: 0.88; 90% CI 0.59–1.32; p = 0.3). The proportion of intolerable grade 2 or any grade ≥3 TEAEs was similar between the two arms (14 mg, 83% vs 18 mg, 80%; p = 0.5). The secondary endpoints of overall ORR, progression-free survival, and overall survival numerically favored the 18-mg arm. A limitation of this study was that the study design did not allow for a full comparison of progression-free survival between treatment arms. Conclusions: The study findings support the approved dosing regimen of lenvatinib 18 mg plus everolimus 5 mg daily for patients with advanced RCC. Patient summary: In this report, we examined two doses of lenvatinib (the approved 18-mg dose and a lower dose of 14 mg) in people with advanced renal cell carcinoma to determine whether the lower dose (which was increased to the approved 18-mg dose after the first treatment cycle) could improve safety without affecting efficacy. The results showed that the efficacy of the lower lenvatinib dose (14 mg) was not the same as that of the approved (18 mg) dose, although safety results were similar, so the approved lenvatinib 18-mg dose should still be used.publishedVersionPeer reviewe

Breast implant-associated anaplastic large cell lymphoma - From diagnosis to treatment

Breast lymphomas comprise a rare group of malignant breast tumors. Among these, a new entity has emerged as a potentially under diagnosed disease. Breast implant-associated anaplastic large cell lymphoma (BI-ALCL) most often manifests as a late periprosthetic effusion between 1 and 10 years after the implantation of silicone or saline-filled breast prostheses. BI-ALCL is an anaplastic lymphoma kinase-negative T-cell lymphoma that has a distinctively different clinical course than other breast lymphomas or ALCLs. Diagnosis is based on aspiration of the effusion around the implant and CD30 positivity of the sample. Every periprosthetic effusion after breast augmentation or reconstruction using implants should be considered as potential BI-ALCL until proven otherwise. The majority of cases at diagnosis are in the in situ stage, i.e., confined to the lumen around the prosthesis. Most patients have an excellent prognosis when complete removal of the capsule and prosthesis with negative margins is achieved surgically. Some patients, however, develop infiltrative disease with a potentially life-threatening clinical course. Treatment planning regarding the extent of surgery and role of adjuvant therapy, especially in advanced cases, requires further investigation.

FDG-PET/CT-guided rebiopsy may find clinically unsuspicious transformation of follicular lymphoma

Aim: The purpose of the study was to evaluate the clinical impact of fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) followed by a new biopsy from the site with maximum standardized uptake value (SUVmax) in case of high maximal SUV values, in detecting clinically unsuspected histologic transformations (HT) of follicular lymphoma (FL). Methods: This retrospective study included all the patients who had undergone FDG-PET/CT during primary diagnosis or relapse of FL between 2010 and 2020 at Oulu University Hospital. Results: The diagnosis changed from an indolent disease to a transformed lymphoma in >10% (7/63) of the patients who underwent diagnostic FDG-PET/CT. The HT risk associated with high SUVmax (>10) was 24% (7 of 29 performed biopsies). Four out of these seven patients with verified HT had no previous clinical suspicion of transformation. Conclusion: Our results suggest that a rebiopsy based on a high SUVmax in diagnostic FDG-PET/CT is valuable in detecting clinically unsuspected HT of FL.publishedVersionPeer reviewe

Lymfoomahoitojen jälkeiset pitkäaikaishaitat, niiden ehkäisy ja seuranta

Tiivistelmä Myöhäishaitat ovat edelleen tavallisia lymfoomahoitojen jälkeen, ja niiden riski jatkuu koko elämän. Vaikka hoitojen kehittyminen on vähentänyt haittoja, varsinkin sekundaarisyövät sekä sydän- ja verisuonitaudit aiheuttavat ylikuolleisuutta. Perusterveydenhuollon tuleekin olla tietoinen mahdollisista ongelmista ja hoitaa riskitekijöitä tehokkaasti. Psykososiaalisten haittojen ehkäisemiseksi tarvitaan lisää tukea potilaille. Suomen Lymfoomaryhmä on tehnyt suosituksen myöhäishaittojen ehkäisemiseksi ja seuraamiseksi.Abstract Prediction and follow-up of long-term side-effects after lymphoma treatment Post-treatment prognosis of lymphoma patients is generally good. However, patients are at risk of developing treatment-related side-effects over time, including secondary malignancies, cardiovascular diseases, infertility and osteoporosis among others. Lymphoma patients are at an increased risk permanently after their treatment. Patients also experience psychosocial side-effects (like fatigue) which can be more long-lasting than physical symptoms. The recommendations of the Finnish Lymphoma Group for surveillance of these patients are presented

Previous radiotherapy improves treatment responses and causes a trend toward longer time to progression among patients with immune checkpoint inhibitor-related adverse events

Abstract Background: Immune-related adverse events (irAEs) are frequently encountered by patients during immune checkpoint inhibitor (ICI) treatment and are associated with better treatment outcomes. The sequencing of radiotherapy (RT) and ICIs is widely used in current clinical practice, but its effect on survival has remained unclear. Methods: In a real-world multicenter study including 521 patients who received ICI treatment for metastatic or locally advanced cancer, RT schedules and timing, irAEs, time to progression, overall survival, and treatment responses were retrospectively reviewed. Results: Patients who received previous RT and developed irAE (RT +/AE +) had the best overall response rate (ORR 44.0%). The ORR was 40.1% in the RT −/AE + group, 26.7% in the RT −/AE − group and 18.3% in the RT + /AE − group (p < 0.001). There was a significantly longer time to progression (TTP) in the RT + /AE + group compared to the RT −/AE − and RT + /AE − groups (log rank p = 0.001 and p < 0.001, respectively), but the trend toward longer TTP in the RT + /AE + group did not reach statistical significance in pairwise comparison to that in the RT −/AE + group. Preceding RT timing and intent had no statistically significant effect on TTP. In a multivariate model, ECOG = 0 and occurrence of irAEs remained independent positive prognostic factors for TTP (HR 0.737; 95% CI 0.582–0.935; p = 0.012, and HR 0.620; 95% CI 0.499–0.769; p < 0.001, respectively). Conclusions: Better ORR and a trend toward longer TTP were demonstrated for patients with RT preceding ICI treatment and development of irAEs, which suggests that RT may boost the therapeutic effect of immunotherapy in patients with metastatic cancers

Geographical differences in the management of metastatic de novo renal cell carcinoma in the era of immune-combinations

BACKGROUND: The upfront treatment of metastatic renal cell carcinoma (mRCC) has been revolutionized by the in-troduction of immune-based combinations. The role of cytoreductive nephrectomy (CN) in these patients is still debated. The ARON-1 study (NCT05287464) was designed to globally analyze real-world data of mRCC patients receiving first -line immuno-oncology combinations. This sub-analysis is focused on the role of upfront or delayed partial or radical CN in three geographical areas (Western Europe, Eastern Europe, America/Asia).METHODS: We conducted a multicenter retrospective observational study in mRCC patients treated with first-line im-mune combinations from 55 centers in 19 countries. From 1152 patients in the ARON-1 dataset, we selected 651 patients with de novo mRCC. 255 patients (39%) had undergone CN, partial in 14% and radical in 86% of cases; 396 patients (61%) received first-line immune-combinations without previous nephrectomy.RESULTS: Median overall survival (OS) from the diagnosis of de novo mRCC was 41.6 months and not reached (NR) in the CN subgroup and 24.0 months in the no CN subgroup, respectively (P<0.001). Median OS from the start of first -line therapy was NR in patients who underwent CN and 22.4 months in the no CN subgroup (P<0.001). Patients who underwent CN reported longer OS compared to no CN in all the three geographical areas.CONCLUSIONS: No significant differences in terms of patients' outcome seem to clearly emerge, even if the rate CN and the choice of the type of first-line immune-based combination varies across the different Cancer Centers participating in the ARON-1 project
