Pretransplantation Inflammatory and Nutritional Status in Elderly Allogeneic Hematopoietic Stem Cell Transplantation: Prognostic Value of C-Reactive Protein-to-Albumin Ratio.

There are no clear criteria for selecting elderly patients with hematologic malignancies eligible for allogeneic hematopoietic stem cell transplantation (HSCT). This study aimed to evaluate inflammatory and nutritional status biomarkers as prognostic indicators of allogeneic HSCT in elderly patients. We compared the prognostic effects of 4 representative pretransplantation biomarkers: C-reactive protein-to-albumin ratio (CAR), Glasgow Prognostic Score (GPS), prognostic nutritional index (PNI), and albumin-to-globulin ratio (AGR). A total of 143 patients age ≥60 years who underwent their first allogeneic HSCT for a hematologic malignancy were enrolled between 2010 and 2020 in our single-center cohort. The median patient age was 65 years (range, 60 to 72 years). Pretransplantation high CAR, high GPS, and low PNI scores were associated with poor overall survival (OS), but the AGR was not associated with OS. Among the 4 biomarkers, CAR stratified OS most significantly (P < .001). Multivariate analyses identified only high CAR as an independent prognostic factor associated with OS (hazard ratio [HR], 1.98; P = .031) and showed that a Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) score ≥3 also was associated with OS (HR, 2.04; P = .012). High CAR was correlated with poor performance status, male sex, and high Disease Risk Index, but not with high HCT-CI score. When the patients were stratified into 3 groups according to a composite risk assessment using CAR and HCT-CI, the 3-year OS decreased significantly with increasing scores (82.8%, 50.3%, and 27.0%, respectively; P < .0001). In conclusion, CAR is the most useful prognostic indicator among the inflammatory and nutritional status biomarkers for allogeneic HSCT in elderly patients. Inflammatory and nutritional status in the elderly may be important prognostic factors for allogeneic HSCT independent of HCT-CI score.

[Acute leukemia developing in the second trimester of pregnancy].

Acute leukemia (AL) during pregnancy poses a substantial risk to both mothers and fetuses. Treatment for leukemia should be initiated promptly; however, the management of AL in pregnant women and fetuses is usually challenging, especially during the second trimester. Here, we report two cases of AL that developed during the second trimester of pregnancy. In one case, chemotherapy was initiated while continuing the pregnancy; in the second case, a cesarean section was performed prior to chemotherapy initiation. As per current medical records, both infants are thriving without any medical problems. The optimal strategy for the treatment of AL during pregnancy typically includes chemotherapy after delivery. However, if fetal development is not sufficient for ex utero survival, the only alternatives available are the initiation of treatment while continuing the pregnancy or treatment after therapeutic abortion (if it is legally allowed). According to previous studies and as per the results from our first case, the initiation of chemotherapy while sustaining the pregnancy may be an acceptable option if it is conducted with appropriate informed consent. The treatment of AL in the second trimester of pregnancy should be carefully decided, while taking into account the medical, legal, and social aspects, such as gestational weeks, maternal and fetal status, and wishes of the patients and their families.
