IMPORTANCE: The current standard-of-care salvage therapy in relapsed/refractory classic Hodgkin lymphoma (cHL) includes consolidation high-dose chemotherapy (HDCT)/autologous stem cell transplant (aSCT). OBJECTIVE: To investigate whether presalvage risk factors and fludeoxyglucose-18 (FDG) positron emission tomography (PET) response to reinduction chemotherapy can guide escalation or de-escalation between HDCT/aSCT or transplant-free consolidation with radiotherapy to minimize toxic effects while maintaining high cure rates. DESIGN, SETTING, AND PARTICIPANTS: EuroNet-PHL-R1 was a nonrandomized clinical trial that enrolled patients younger than 18 years with first relapsed/refractory cHL across 68 sites in 13 countries in Europe between January 2007 and January 2013. Data were analyzed between September 2022 and July 2024. INTERVENTION: Reinduction chemotherapy consisted of alternating IEP (ifosfamide, etoposide, prednisolone) and ABVD (adriamycin, bleomycin, vinblastine, dacarbazine). Patients with low-risk disease (late relapse after 2 cycles of first-line chemotherapy and any relapse with an adequate response after 1 IEP/ABVD defined as complete metabolic response on FDG-PET and at least 50% volume reduction) received a second IEP/ABVD cycle and radiotherapy (RT) to all sites involved at relapse. Patients with high-risk disease (all primary progressions and relapses with inadequate response after 1 IEP/ABVD cycle) received a second IEP/ABVD cycle plus HDCT/aSCT with or without RT. MAIN OUTCOMES AND MEASURES: The primary end point was 5-year event-free survival. Secondary end points were overall survival (OS) and progression-free survival (PFS). PFS was identical to event-free survival because no secondary cancers were observed. PFS data alone are presented for simplicity. RESULTS: Of 118 patients analyzed, 58 (49.2%) were female, and the median (IQR) age was 16.3 (14.5-17.6) years. The median (IQR) follow-up was 67.5 (58.5-77.0) months. The overall 5-year PFS was 71.3% (95% CI, 63.5%-80.1%), and OS was 82.7% (95% CI, 75.8%-90.1%). For patients in the low-risk group (n = 59), 41 received nontransplant salvage with a 5-year PFS of 89.7% (95% CI, 80.7%-99.8%) and OS of 97.4% (95% CI, 92.6%-100%). In contrast, 18 received HDCT/aSCT off protocol, with a 5-year PFS of 88.9% (95% CI, 75.5%-100%) and OS of 100%. All 59 patients with high-risk disease received HDCT/aSCT (and 23 received post-HDCT/aSCT RT) with a 5-year PFS of 53.3% (95% CI, 41.8%-67.9%) and OS of 66.5% (95% CI, 54.9%-80.5%). CONCLUSION AND RELEVANCE: In this nonrandomized clinical trial, FDG-PET response-guided salvage in relapsed cHL may identify patients in whom transplant-free salvage achieves excellent outcomes. HDCT/aSCT may be reserved for primary progression and relapsed cHL with inadequate response. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00433459.

STUDY QUESTION: What is the impact of the EuroNet-PHL-C2 treatment for boys with classical Hodgkin lymphoma (cHL) on semen parameters? SUMMARY ANSWER: More than half of the patients (52%, n = 16/31) had oligozoospermia or azoospermia at 2 years from cHL diagnosis; particularly boys treated for advanced-stage cHL had low sperm counts and motility. WHAT IS KNOWN ALREADY: Chemotherapy and radiotherapy to the inguinal region or testes can impair spermatogenesis and result in reduced fertility. The EuroNet-PHL-C2 trial aims to minimize radiotherapy in standard childhood cHL treatment, by intensifying chemotherapy. The present study aims to assess the (gonadotoxic) impact of this treatment protocol on semen parameters and reproductive hormones in boys aged ≤18 years. STUDY DESIGN, SIZE, DURATION: This international, prospective, multi-centre cohort study was an add-on study to the randomized phase-3 EuroNet-PHL-C2 trial, where the efficacy of standard cHL treatment with OEPA-COPDAC-28 (OEPA: vincristine, etoposide, prednisone, and doxorubicin; COPDAC-28: cyclophosphamide, vincristine, prednisone, and dacarbazine) was compared to intensified OEPA-DECOPDAC-21 chemotherapy (DECOPDAC-21: COPDAC with additional doxorubicin and etoposide and 25% more cyclophosphamide). Patients were recruited between January 2017 and September 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: Eligibility criteria included male patients, diagnosed with classical HL before or at the age of 18 years, and treated according to the EuroNet-PHL-C2 protocol in any of the 18 participating sites in the Netherlands, Germany, Belgium, Czech Republic, and Austria. Sperm parameters (sperm concentration, progressive motility, sperm volume, and calculated total motile sperm count) were assessed at diagnosis and 2 years after diagnosis in (post)pubertal boys. Laboratory measurements (serum follicle-stimulating hormone (FSH) and inhibin B) were performed in samples drawn at diagnosis, during treatment (2-3 times), and at 2 years post-diagnosis, and (age-adjusted) analyses were conducted separately for pre-pubertal and (post)pubertal boys. Outcomes were compared between the treatment levels (TL1, TL2, and TL3) and consolidation treatment schemes (COPDAC-28 and DECOPDAC-21). MAIN RESULTS AND THE ROLE OF CHANCE: In total, 101 boys were included in the present analysis: 73 were (post)pubertal (median age 15.4 years, (IQR 14.4; 16.6), 10 TL1, 29 TL2, 34 TL3, 62% of TL2/3 patients received COPDAC-28) and 28 boys were pre-pubertal (median age 9.6 years (IQR 6.6; 11.4), 4 TL1, 7 TL2, 17 TL3, 38% of TL2/3 patients received COPDAC-28). The study included six boys who had received pelvic radiotherapy; none were irradiated in the inguinal or testicular area. At diagnosis, 48 (post)pubertal boys delivered semen for cryopreservation; 19 (40%) semen samples were oligospermic and 4 (8%) were azoospermic. Low sperm concentration (<15 mil/ml) appeared to be related to the HL disease itself, with a higher prevalence in boys who presented with B symptoms (76% vs 26%, aOR 2.3 (95% CI 1.0; 3.8), P = 0.001) compared to those without such symptoms. At 2 -years post-diagnosis, 31 boys provided semen samples for analysis, of whom 12 (39%) boys had oligozoospermia and 4 (13%) had azoospermia, while 22 boys (71%) had low total motile sperm counts (TMSC) (<20 mil). Specifically, the eight boys in the TL3 group treated with DECOPDAC-21 consolidation had low sperm counts and low progressive motility after 2 years (i.e. median sperm count 1.4 mil/ml (IQR <0.1; 5.3), n = 7 (88%), low sperm concentration, low median progressive motility 16.5% (IQR 0.0; 51.2), respectively). Age-adjusted serum FSH levels were significantly raised and inhibin B levels (and inhibin B:FSH ratios) were decreased during chemotherapy in (post)pubertal boys, with subsequent normalization in 80% (for FSH) and 60% (for inhibin B) of boys after 2 years. Only 4 out of the 14 (post)pubertal boys (29%) with low sperm concentrations after 2 years had elevated FSH (>7.6 IU/l), while 7 (50%) had low inhibin B levels (<100 ng/l). In pre-pubertal boys, reproductive hormones were low overall and remained relatively stable during chemotherapy. LIMITATIONS, REASONS FOR CAUTION: The present analyses included sperm and laboratory measurements up to 2 years post-diagnosis. Long-term reproductive outcomes and potential recovery of spermatogenesis remain unknown, while recovery was reported up to 5- or even 10-year post-chemotherapy in previous studies.Boys who were pre-pubertal at diagnosis were still too young and/or physically not able to deliver semen after 2 years and we could not assess a potential difference in gonadotoxicity according to pubertal state at the time of treatment. Overall, the statistical power of the analyses on sperm concentration and quality after 2 years was limited. WIDER IMPLICATIONS OF THE FINDINGS: Results of the semen analyses conducted among the 31 boys who had provided a semen sample at 2 years post-treatment were generally poor. However, additional long-term and adequately powered data are crucial to assess the potential recovery and clinical impact on fertility. The participating boys will be invited to deliver a semen sample after 5 years. Until these data become available, benefits of intensified chemotherapy in cHL treatment to reduce radiotherapy and lower risk for development of secondary tumours should be carefully weighed against potentially increased risk of other late effects, such as diminished fertility due to the increased chemotherapy burden. Boys with newly diagnosed cHL should be encouraged to deliver sperm for cryopreservation whenever possible. However, patients and clinicians should also realize that the overall state of disease and inflammatory milieu of cHL can negatively affect sperm quality and thereby reduce chance of successful fertility preservation. Furthermore, the measurement of FSH and inhibin B appears to be of low value in predicting low sperm quality at two years from cHL treatment.

Hemofagocytující lymfohistiocytóza (HLH) je syndrom nepřiměřeně silné zánětlivé odpovědi vyvolaný excesivní aktivací lymfocytů a makrofágů s následnou nadprodukcí cytokinů, které způsobují život ohrožující orgánové poškození. Postihuje pacienty s vrozenými genetickými abnormitami, krevními malignitami, chronickými zánětlivými stavy nebo infekcí. Nejčastějšími příznaky onemocnění jsou horečka, cytopenie v periferní krvi, splenomegalie, hyperferitinémie, transaminitida. Včasná diagnóza spouštěče HLH, jakým je virová infekce nebo malignita, je pro zlepšení osudu pacientů klíčová. Léčbu HLH je často nutné zahájit před stanovením diagnózy predisponujícího onemocnění. Léčbou první volby může v takové situaci být kombinace kortikosteroidů a anakinry. Pacienti s primární HLH vyžadují intenzivní léčbu kombinací kortikoidů a etoposidu a většinou jsou indikováni k alogenní transplantaci krvetvorných buněk.
Haemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome induced by excessive activation of lymphocytes and macrophages producing a cytokine storm. The result may be life-threatening organ damage. HLH develops in patients with genetic abnormalities, haematological malignancies, chronic inflammatory conditions, or infections. The most frequent clinical and laboratory features are fever, cytopenia, splenomegaly, hyperferritinemia, and transaminitis. Early identification of a HLH trigger, such as malignancy or viral infection, is crucial for improving patient outcomes. Treatment has to be frequently started before the diagnosis of a predisposing condition. The treatment of first choice in such situations may involve the combination of corticosteroids and anakinra. Patients with primary HLH require intensive therapy consisting of corticosteroids and etoposide followed by allogeneic hematopoietic stem cell transplantation.

Ifosfamid je protinádorový lék ze skupiny alkylačních cytostatik, jenž zabudováním alkylové skupiny do řetězce DNA naruší replikaci nukleotidových řetězců. Jedná se sice již o historický medikament, jehož vznik se datuje do 70. let minulého století, ale stále se s ním běžně setkáváme v onkologické praxi, např. u nádorů kostí, sarkomů měkkých tkání, ale i recidivujících nonhodgkinských lymfomů či lymfomů CNS. Tato terapie je zatížena řadou nežádoucích účinků, z nichž ke klasickým akutním nežádoucím účinkům patří reverzibilní encefalopatie a hemoragická cystitida. V této kazuistice z německé kliniky bych se rád zaměřil na renální toxicitu ifosfamidu, respektive poškození proximálního tubulu, v jehož důsledku se může rozvinout až tzv. Fanconiho synrom.
Ifosfamide is an anticancer drug from the group of alkylating cytostatics that disrupts the replication of nucleotide chains by incorporating an alkyl group into the DNA chain. Although it is a historical drug dating back to the 1970s, it is still commonly encountered in cancer treatment, e. g. in bone tumours, sarcomas and recurrent non-Hodgkin's lymphomas or CNS lymphomas. This therapy is burdened with a number of adverse effects, of the classic acute side effects include reversible encephalopathy and hemorrhagic cystitis. In this case report, I would like to focus on the renal toxicity of ifosfamide or damage to the proximal tubule, which may result in the development of Fanconi syndrome.

Recent studies have highlighted the significant role of 5-hydroxymethylcytosine (5hmC) in carcinogenesis. However, the specific role of 5hmC in osteosarcoma (OS) remains largely unexplored. The-re-fore, this study aimed to investigate the function of 5hmC and TET3 in OS. In this study, we found a decreased total level of 5hmC in OS tissues. The expression of the TET3 protein was also decreased in OS. Importantly, the decreased levels of TET3 were associated with a decreased disease-free survival (DFS) rate in patients. To investigate the role of TET3 and 5hmC in OS, we manipulated the levels of TET3 in MG-63 cells. Silencing TET3 in these cells resulted in a twofold increase in proliferation. Additio-nally, the level of 5hmC decreased in these cells. Con-versely, over-expression of TET3 in MG-63 cells led to the expected inhibition of proliferation and invasion, accompanied by an increase in 5hmC levels. In conclusion, both 5hmC and TET3 protein levels were decreased in OS. Additionally, the over-expression of TET3 inhibited the proliferation of MG-63 cells, while the suppression of TET3 had the opposite effect. These findings suggest that decreased levels of 5hmC and TET3 may serve as potential markers for OS.

This study compared decitabine exposure when administered IV (DEC-IV) at a dose of 20 mg/m2 for 5-days with orally administered decitabine with cedazuridine (DEC-C), as well as the clinical efficacy and safety of DEC-C in patients with acute myeloid leukaemia (AML) who were ineligible for intensive induction chemotherapy. In all, 89 patients were randomised 1:1 to DEC-IV or oral DEC-C (days 1-5 in a 28-day treatment cycle), followed by 5 days of the other formulation in the next treatment cycle. All patients received oral DEC-C for subsequent treatment cycles until treatment discontinuation. Equivalent systemic decitabine exposures were demonstrated (5-day area under the curve ratio between the two decitabine formulations of 99.64 [90% confidence interval 91.23%, 108.80%]). Demethylation rates also were similar (≤1.1% difference). Median overall survival (OS), clinical response and safety profile with oral DEC-C were consistent with those previously observed with DEC-IV. Next-generation sequencing was performed to identify molecular abnormalities that impact OS and TP53 mutations were associated with a poor outcome. These findings support the use of oral DEC-C in patients with AML.

MicroRNA hsa-miR-29 was connected to a number of malignancies. Its target genes are many, among them Mcl-1 that is expressed in three possible isoforms, one of which is anti-apoptotic and another one pro-apoptotic. Ratio of these two isoforms appears to affect cell response to external stimuli. We have demonstrated that miR-29b enhanced etoposide toxicity in HeLa cell line by modulating this ratio of Mcl-1 isoforms. However, it is not known whether the described miR-29 effect is common to various cancer types or even have the opposite effect. This represents a significant problem for possible future applications. In this report, we demonstrate that miR-29b affects toxicity of 60 μM etoposide in cell lines derived from selected malignancies. The mechanism, however, differs among the cell lines tested. Hep G2 cells demonstrated similar effect of miR-29b on etoposide toxicity as was described in HeLa cells, i.e. modulation of Mcl-1 expression. Target protein down-regulated by miR-29b resulting in enhanced etoposide toxicity in Caco-2 cells was, however, Bcl-2 protein. Moreover, H9c2, Hek-293 and ARPE-19 cell lines selected as a representatives of non-malignant cells, showed no effect of miR-29b on etoposide toxicity. Our data suggest that miR-29b could be a common enhancer of etoposide toxicity in malignant cells due to its modulation of Bcl family proteins.

OBJECTIVES: IMbrella A is a Phase III extension study that allowed rollover from Roche/Genentech-sponsored atezolizumab trials, including IMpower133, a Phase I/III trial of first-line atezolizumab or placebo plus carboplatin/etoposide in extensive-stage small cell lung cancer. We report outcomes from an exploratory analysis of IMpower133 with extended time-to-event data for patients who rolled over to IMbrella A. MATERIALS AND METHODS: IMpower133 patients could roll over to IMbrella A to receive atezolizumab 1200 mg intravenously every three weeks if they continued to receive atezolizumab at IMpower133 closure or were in survival follow-up after atezolizumab discontinuation. Overall survival and safety were assessed; only serious adverse events and AEs of special interest were collected in IMbrella A. RESULTS: Eighteen of 26 eligible patients rolled over to IMbrella A. At clinical cutoff (March 16, 2023), median follow-up in the atezolizumab plus carboplatin/etoposide arm (IMpower133 and IMbrella A) was 59.4 months. The three-, four-, and five-year overall survival (95 % CI) estimates were 16 % (11 %-21 %), 13 % (8 %-18 %), and 12 % (7 %-17 %), respectively. In IMbrella A, serious adverse events occurred in three patients (16.7 %), and one adverse event of special interest was reported (grade two hypothyroidism). CONCLUSION: This long-term analysis of patients from IMbrella A previously enrolled in IMpower133 provides the first report of five-year overall survival outcomes in patients with extensive-stage small cell lung cancer treated with first-line cancer immunotherapy and chemotherapy. While limited by small patient numbers and lack of long-term data for the IMpower133 control arm, exploratory overall survival analyses in patients treated with atezolizumab plus carboplatin/etoposide compared favorably with historical data with chemotherapy alone. NCT03148418.

Extenzivní stadium malobuněčného plicního karcinomu (extensive-stage small cell lung cancer, ES-SCLC) je malignita se stále špatnou prognózou. Pacienti s ES-SCLC by měli být v první linii první čtyři cykly léčeni kombinací platiny s etoposidem a s durvalumabem anebo s atezolizumabem, následně by měli pokračovat udržovací imunoterapií. Zmíněná kombinační léčba zlepšuje přežití nemocných. Tato kazuistika popisuje případ 68leté pacientky, která je durvalumabem úspěšně léčena.
Extensive-stage small cell lung cancer (ES-SCLC) is a malignancy with a still poor prognosis. Patients with ES-SCLC should be treated with first-line platinum and etoposide plus either durvalumab or atezolizumab for four cycles followed by maintenance immunotherapy. Mentioned combination therapy improves survival of patients. This clinical case reports a successful treatment with durvalumab of a 68 years old patient.

Primary hemophagocytic lymphohistiocytosis (pHLH) is a life-threatening hyperinflammatory syndrome that develops mainly in patients with genetic disorders of lymphocyte cytotoxicity and X-linked lymphoproliferative syndromes. Previous studies with etoposide-based treatment followed by hematopoetic stem cell transplantation (HSCT) resulted in 5-year survival of 50% to 59%. Contemporary data are lacking. We evaluated 88 patients with pHLH documented in the international HLH registry from 2016-2021. In 12 of 88 patients, diagnosis was made without HLH activity, based on siblings or albinism. Major HLH-directed drugs (etoposide, antithymocyte globulin, alemtuzumab, emapalumab, ruxolitinib) were administered to 66 of 76 patients who were symptomatic (86% first-line etoposide); 16 of 57 patients treated with etoposide and 3 of 9 with other first-line treatment received salvage therapy. HSCT was performed in 75 patients; 7 patients died before HSCT. Three-year probability of survival (pSU) was 82% (confidence interval [CI], 72%-88%) for the entire cohort and 77% (CI, 64%-86%) for patients receiving first-line etoposide. Compared with the HLH-2004 study, both pre-HSCT and post-HSCT survival of patients receiving first-line etoposide improved, 83% to 91% and 70% to 88%. Differences to HLH-2004 included preferential use of reduced-toxicity conditioning and reduced time from diagnosis to HSCT (from 148 to 88 days). Three-year pSU was lower with haploidentical (4 of 9 patients [44%]) than with other donors (62 of 66 [94%]; P < .001). Importantly, early HSCT for patients who were asymptomatic resulted in 100% survival, emphasizing the potential benefit of newborn screening. This contemporary standard-of-care study of patients with pHLH reveals that first-line etoposide-based therapy is better than previously reported, providing a benchmark for novel treatment regimes.
