Abstract: Improved long-term survival rates after allogeneic hematopoietic cell transplantation (alloHCT) make family planning for young adult cancer survivors an important topic. However, treatment-related infertility risk poses challenges. To assess pregnancy and birth rates in a contemporary cohort, we conducted a national multicenter study using data from the German Transplant Registry, focusing on adult women aged 18 to 40 years who underwent alloHCT between 2003 and 2018. Of 2654 women who underwent transplantation, 50 women experienced 74 pregnancies, occurring at a median of 4.7 years after transplant. Fifty-seven of these resulted in live births (77%). The annual first birth rate among HCT recipients was 0.45%, which is >6 times lower than in the general population. The probability of a live birth 10 years after HCT was 3.4%. Factors associated with an increased likelihood of pregnancy were younger age at alloHCT, nonmalignant transplant indications, no total body irradiation or a cumulative dose of <8 Gy, and nonmyeloablative/reduced-intensity conditioning. Notably, 72% of pregnancies occurred spontaneously, with assisted reproductive technologies used in the remaining cases. Preterm delivery and low birth weight were more common than in the general population. This study represents the largest data set reporting pregnancies in a cohort of adult female alloHCT recipients. Our findings underscore a meaningful chance of pregnancy in alloHCT recipients. Assisted reproductive technologies techniques are important and funding should be made available. However, the potential for spontaneous pregnancies should not be underestimated, and patients should be informed of the possibility of unexpected pregnancy despite reduced fertility. Further research is warranted to understand the impact of conditioning decisions on fertility preservation., (© 2024 American Society of Hematology. Published by Elsevier Inc.

Background: Secondary central nervous system lymphoma (SCNSL) confers a dismal prognosis and treatment advances are constrained by the lack of prospective studies and real-world treatment evidence., Methods: Patients with SCNSL of all entities were included at first diagnosis and patient characteristics, treatment data, and outcomes were prospectively collected in the Secondary CNS Lymphoma Registry (SCNSL-R) (NCT05114330)., Findings: 279 patients from 47 institutions were enrolled from 2011 to 2022 and 243 patients (median age: 66 years; range: 23-86) were available for analysis. Of those, 49 (20 %) patients presented with synchronous (cohort I) and 194 (80 %) with metachronous SCNSL (cohort II). The predominant histology was diffuse large B-cell lymphoma (DLBCL, 68 %). Median overall survival (OS) from diagnosis of CNS involvement was 17·2 months (95 % CI 12-27·5), with longer OS in cohort I (60·6 months, 95 % CI 45·5-not estimable (NE)) than cohort II (11·4 months, 95 % CI 7·8-17·7, log-rank test p < 0.0001). Predominant induction regimens included R-CHOP/high-dose MTX (cohort I) and high-dose MTX/cytarabine (cohort II). Rituximab was used in 166 (68 %) of B-cell lymphoma. Undergoing consolidating high-dose therapy and autologous hematopoietic stem cell transplantation (HDT-ASCT) in partial response (PR) or better was associated with longer OS (HR adjusted 0·47 (95 % CI 0·25-0·89), p = 0·0197)., Interpretation: This study is the largest prospective cohort of SCNSL patients providing a comprehensive overview of an international real-world treatment landscape and outcomes. Prognosis was better in patients with SCNSL involvement at initial diagnosis (cohort I) and consolidating HDT-ASCT was associated with favorable outcome in patients with PR or better., Competing Interests: Declaration of Competing Interest U.Ke. served in an advisory role for BMS/ Celgene, Takeda, Janssen, Gilead/ Kite, Roche, Abbvie, AstraZeneca, Novartis, Lilly, Pentixapharm and received travel support from BMS/ Celgene, Takeda, Janssen, Roche, Abbvie, Gilead/ Kite, AstraZeneca, Novartis, Lilly, Pentixapharm.

High-dose chemotherapy followed by autologous stem cell transplantation has been shown to be feasible and highly effective in newly diagnosed primary central nervous system lymphoma. In this retrospective multicenter study, we investigated prognosis and baseline risk factors in patients with primary central nervous system lymphoma who underwent this treatment approach. We retrospectively analyzed 105 immunocompetent patients with primary central nervous system lymphoma who underwent high-dose chemotherapy followed by autologous stem cell transplantation with or without whole brain radiotherapy as first-line consolidation treated at 12 German centers between 1997 and 2011. We estimated survival rates and investigated the impact of age, performance status, serum lactate dehydrogenase level, and deep brain involvement on overall and progression-free survival. Patients were additionally categorized into three prognostic groups according to the Memorial Sloan Kettering Cancer Center prognostic model. After a median follow up of 47 months, median progression-free survival and overall survival was reached after 85 and 121 months; 2- and 5-year survival rates were 82% and 79%, respectively. The Memorial Sloan Kettering Cancer Center prognostic model did not predict survival. Only age revealed some evidence of prognostic relevance. Overall response rate was 95%; of those patients with progressive disease before high-dose chemotherapy, 7 of 20 achieved ongoing complete remission after therapy without whole brain radiation therapy. Transplantation-associated mortality was 2.8%. High-dose chemotherapy followed by autologous stem cell transplantation is a highly effective and safe treatment modality for selected primary central nervous system lymphoma patients. Superiority compared to standard chemotherapy still warrants further investigation. more...

Objective: To assess the outcome of elderly patients with primary CNS lymphoma (PCNSL) treated within the G-PCNSL-SG-1 trial., Methods: We reviewed response, toxicity, and survival of patients with PCNSL aged 70 or more enrolled in the G-PCNSL-SG-1 trial., Results: A total of 126 of the 526 eligible patients (24%) and 66 of 318 patients (21%) in the per protocol population were aged 70 or more. Among all eligible patients, the rate of complete and partial responses (CR+PR) to HD-MTX-based chemotherapy was 44% in the elderly vs 57% in the younger patients (p = 0.016). Toxicity was age-independent except for a higher rate of grade III/IV leukopenia in the elderly (34% vs 21%, p = 0.007). Death on therapy was more frequent (18% vs 11%; p = 0.027), and progression-free survival (PFS) (4.0 vs 7.7 months, p = 0.014) and overall survival (12.5 vs 26.2 months, p < 0.001) inferior, in the elderly. A striking difference between younger and elderly patients was the PFS of CR patients of 35.0 in the younger vs 16.1 in the elderly patients (p = 0.024). Elderly patients were treated less often and less aggressively at salvage. However, age was not associated with survival from salvage whole brain radiotherapy in patients progressing during primary HD-MTX-based chemotherapy (p = 0.633)., Conclusions: Lower response rate and higher mortality on HD-MTX-based chemotherapy as well as lower PFS of CR patients and less salvage therapy contribute to the poor prognosis of elderly patients with PCNSL. more...
