Impact of Skeletal Muscle Depletion on Patients with Myelodysplastic Syndrome Treated with Azacitidine.

BACKGROUND: Azacitidine (AZA) is the standard treatment for patients with high-risk myelodysplastic syndromes (MDS). The impact of skeletal muscle depletion (SMD), which is associated with outcomes of hematological malignancies, on the clinical course of MDS patients treated with AZA was investigated. METHODS: This retrospective, observational study included 50 MDS patients treated with AZA. Muscle mass was evaluated using the skeletal muscle index (SMI), which is the area of muscle mass at the third lumbar vertebra on CT images divided by the square of the height. RESULTS: Of the enrolled patients, 39 were males, and their median age was 69.5 years. Twenty-seven (20 male and 7 female) patients showed SMD. The median survival was 13.4 months in the SMD group and 15.2 months in the non-SMD group, with no significant difference and no significant association between the response rate or severe non-hematological toxicities and the presence of SMD. By contrast, grade 3-4 anemia and thrombocytopenia were significantly more frequent in the SMD group than in the non-SMD group. SMD was associated with severe anemia and thrombocytopenia in MDS patients treated with AZA. CONCLUSION: Reduced skeletal muscle mass may predict severe hematological toxicity in MDS patients treated with AZA.

Cohort profile: rationale and design of the Resource Center for Health Science (RECHS) project - a study of health hazards and medical cost burden among the Japanese population.

PURPOSE: The increased global burden of non-communicable diseases and mental disorders is an urgent health challenge for countries around the entire world, especially those experiencing super-ageing societies, where over 21% of the population is age 65 years or older. Japan is the world's most rapidly ageing society, and as a result, medical costs are also rising dramatically. With the aims of establishing a foundational framework for future research efforts, primarily focusing on the development of a personal health record (PHR) system, and creating a long-term repository for bioresources integrated with PHRs, this study investigated potential health risks and future healthcare burdens based on a longitudinal analysis of health records. PARTICIPANTS: The Resource Center for Health Science (RECHS) project is a long-term, prospective biobank project, population and health check-up-based cohort that primarily investigates the associations between lifestyle and environmental factors and some surrogate markers of non-communicable diseases, such as diabetes, hypertension, cardiovascular disease and cancer. Starting in 2010, we initiated an annual cohort study among voluntary participants recruited from health check-up programmes and collected data from the following sources: a self-administered baseline questionnaire that included items on dietary habits and stress, a Brief Self-Administered Diet History Questionnaire, the Centre for Epidemiologic Studies Depression Scale and the General Health Questionnaire-28. FINDINGS TO DATE: For this prospective cohort study, we planned to enrol approximately 10 000 participants. We collected and stored serum samples from all participants for future analyses. The study participants who still were able to participate in these health check-ups and their outcomes were then obtained from the measurements and questionnaire responses. FUTURE PLANS: Insights emerging from the RECHS study can provide researchers and public health policy administrators with evidence to aid in the prevention of non-communicable diseases and clarify the most malleable status to implement preventive measures.

Filgrastim-induced hemophagocytic lymphohistiocytosis in a patient with mantle cell lymphoma: A case report.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease potentially induced by various causes. Very few reports have described HLH induced by granulocyte colony-stimulating factor (G-CSF) and those few previous reports have uniformly indicated that continuing G-CSF is unfeasible once HLH has been induced. A 52-year-old Japanese man who had been diagnosed with mantle cell lymphoma with systemic and central nervous system involvements received rituximab, hyper-fractionated cyclophosphamide, vincristine, Adriamycin and dexamethasone (R-HCVAD)/methotrexate and cytarabine. During the second cycle of R-HCVAD, the patient developed severe back pain, thrombocytopenia, elevated serum lactate dehydrogenase and ferritin levels, and hemophagocytosis in the bone marrow. Complete remission (CR) of mantle cell lymphoma was confirmed on whole-body computed tomography, brain magnetic resonance imaging, and bone marrow biopsy. The patient was diagnosed with HLH induced by filgrastim. HLH recovered with intravenous methylprednisolone at 1 g/day for 3 days, followed by oral prednisolone tapered off over 5 days. The patient continued chemotherapy with a change in the G-CSF formulation from filgrastim to lenograstim and prophylactic administration of corticosteroids. He safely completed scheduled chemotherapy without recurrence of HLH and successfully maintained CR of lymphoma. Although rare, G-CSF potentially induces HLH. Changing the G-CSF formulation and steroid prophylaxis may allow safe continuation of G-CSF.

A phase II study of gemcitabine, carboplatin, dexamethasone, and rituximab in patients with relapsed or refractory non-Hodgkin lymphoma.

This study evaluated the efficacy and safety of salvage chemotherapy with gemcitabine, carboplatin, dexamethasone, and rituximab (GCD ± R) for Japanese patients with relapsed or refractory non-Hodgkin lymphoma (NHL). A multicenter, phase II trial of GCD ± R administered every 3 weeks for up to 6 cycles was conducted. Rituximab was administered as a therapeutic strategy for CD20-positive lymphoma. The primary endpoint was the complete response (CR) rate. Secondary endpoints included the overall response (OR) rate, overall survival (OS), progression-free survival (PFS), toxicity, and success rate of peripheral blood stem cell collection for eligible transplant patients. A total of 25 patients (median age 66 years) were evaluated, with a median follow-up period of 66.7 months. CR and OR rates were 28% and 52%, respectively. Median PFS and OS were 8.7 and 32.2 months, respectively. The major toxicity was myelosuppression, but the regimen was generally well-tolerated, with a low incidence of febrile neutropenia (20%) and no treatment-related deaths. Of the 6 patients who were eligible for autologous stem cell transplantation and underwent peripheral blood stem cell mobilization, the required number of CD34-positive cells was collected in 5 (83%). All 6 proceeded to transplantation and achieved successful engraftment without recurrence. The present results suggest that GCD ± R may be effective and well-tolerated in Japanese patients with relapsed or refractory NHL. However, further investigation is needed to confirm these results.

The pretreatment Controlling Nutritional Status score is an independent prognostic factor in elderly patients with diffuse large B-cell lymphoma.

Predicting prognosis is crucial in older patients with diffuse large B-cell lymphoma (DLBCL). This study evaluated the prognostic impact of the controlling nutritional status (CONUT) score, a simple nutritional index, for older DLBCL patients (≥65 years of age) treated with R-CHOP-like regimens in a retrospective, cohort study including 203 patients. The CONUT score was an independent prognostic factor for overall survival (hazard ratio 1.11, 95% confidence interval (CI) 1.01-1.21, p = 0.032) in a multivariable Cox proportional hazards model. On receiver-operating characteristic analysis, the optimal cutoff value was 3. The CONUT score (≥3 or <3) effectively stratified older DLBCL patients, regardless of the International Prognostic Index (p = 0.71 for interaction). Further, the CONUT score independently affected initial dose intensity (odds ratio 0.84, 95% CI 0.73-0.95, p = 0.008), likely reflecting the patients' status at diagnosis and affecting dose adjustments. In conclusion, the CONUT score is associated with a poorer prognosis in older DLBCL patients.

Comparison of the prognostic impact of IPI and PIT in peripheral T-cell lymphoma in real-world practice with a large elderly population.

We compared the predictive ability of the International Prognostic Index (IPI), a frequently used prognostic model for peripheral T-cell lymphoma (PTCL), with that of a type-specific prognostic model, the Prognostic Index for PTCL-U (PIT). We retrospectively analyzed 113 patients diagnosed with PTCL. The median age was 67 years (range, 16-88 years), 75 patients (66%) were male, and the most common disease type was PTCL, not otherwise specified (69%). With a median follow-up of 6.8 years (interquartile range, 2.7-9.9 years), 5-year survival rates for the four groups in IPI were 85%, 62%, 49%, and 13%, respectively. Similarly, 5-year survival rates for the four groups in PIT were 83%, 64%, 49%, and 19%, respectively. The area under the receiving operating characteristic curve for predicting mortality from PIT (0.725) was not significantly different from that from the IPI (0.685, P = 0.134). Multivariable analysis showed that performance status ≥ 2 (P < 0.0001) and extranodal lesions ≥ 2 (P = 0.029) were significantly associated with lower overall survival. The present study found no significant difference in prognostic ability between the IPI and PIT for PTCL, and both models appear useful as predictive models.

The Relative Dose Intensity Changes during Cycles of Standard Regimens in Patients with Diffuse Large B-Cell Lymphoma.

No studies have focused on the trajectory of the average relative dose intensity (ARDI) during cycles of first-line chemotherapy for patients with diffuse large B-cell lymphoma. To evaluate the impact of attenuating ARDI during cycles on overall survival, we conducted a multi-centre, longitudinal, observational retrospective study. A total of 307 analysable patients were enrolled. Multivariate Cox hazards modelling with restricted cubic spline models revealed prognostic benefits of higher ARDI up to, but not after, cycle 6. According to group-based trajectory modelling, patients were classified into five groups depending on the pattern of ARDI changes. Among these, two groups in which ARDI had fallen significantly to less than 50% by cycles 4-6 displayed significantly poorer prognosis, despite increased ARDI in the second half of the treatment period (log-rank p = 0.02). The Geriatric Nutritional Risk Index offered significant prediction of unfavourable ARDI changes (odds ratio 2.540, 95% confidence interval 1.020-6.310; p = 0.044). Up to cycle 6, maintenance of ARDI in all cycles (but particularly in the early cycles) is important for prognosis. Malnutrition is a significant factor that lets patients trace patterns of ARDI changes during cycles of chemotherapy associated with untoward prognosis.

Assessment of satisfaction with antiretroviral drugs and the need for long-acting injectable medicines among people living with HIV in Japan and its associated factors: a prospective multicenter cross-sectional observational study.

BACKGROUND: Long-acting injectable formulations for HIV infection have been approved and are now available in Japan. Although not currently recommended as first-line drugs in Japanese or overseas guidelines, use of such formulations may increase, in accordance with patient conditions and preference. We determine the level of satisfaction with current anti-HIV drugs and analyzed the preferences of patients who favor long-acting injectable drugs based on their satisfaction level with the present anti-HIV drugs. METHODS: People living with HIV (PLWH) who had received antiretroviral therapy (ART) for at least one month and consented to the study between 1 April and 31 December 2021 were included in a survey conducted using a self-administered questionnaire. The content of the survey included satisfaction with seven items (tablet size, ease and feeling when taking the medicine, color, taste, portability, daily oral therapy, and co-payment) related to the anti-HIV drugs they were taking and their need for future drugs (dosage form, frequency of dosing, long-acting injectable, etc.). In addition, factors related to the need for long-acting injectable medications were analyzed with regard to the relationship with satisfaction with anti-HIV drugs. RESULTS: Overall, 667 patients available for analysis were included in this study. Satisfaction with anti-HIV drugs was highest with regard to "co-payment" and lowest with "daily oral therapy". Regarding the need for long-acting injectable medications, logistic regression analysis indicated that tablet size and daily oral therapy were significant predictors of patient preference for a once-every-eight-weeks intramuscular formulation in terms of their requirement for long-acting injectable medications (tablet size, OR = 2.14, 95%CI 1.030-4.430, p = 0.042; and daily oral therapy, OR = 1.75, 95%CI 1.010-3.030, p = 0.044). CONCLUSIONS: Patients currently receiving anti-HIV drugs who express dissatisfaction with tablet size and daily oral therapy may prefer a long-acting injectable formulation, taking into consideration patient age, employment status, ART history, frequency of daily dosage and concomitant medications other than ART.

Prognostic significance of the Geriatric 8 score alone and included with genetic risk group in older adults with acute myeloid leukemia.

INTRODUCTION: As the numbers of older adult patients with acute myeloid leukemia (AML) continue to increase, the establishment of a simple geriatric assessment specifically for AML represents an unmet need. This study aimed to assess the impact of the Geriatric 8 (G8) score on overall survival (OS). MATERIALS AND METHODS: We retrospectively analyzed 100 patients ≥60 years old with newly diagnosed AML. RESULTS: Multivariate Cox modeling identified G8 score as a significant prognostic factor for OS (hazard ratio 0.891, 95% confidence interval [CI] 0.808-0.983). A linear association between G8 score and mortality risk was confirmed in a Cox model with restricted cubic spline. Multivariate receiver operating characteristic curves demonstrated a significant improvement in prediction ability when G8 score was added to cytogenetic risk group. The combination of G8 score and cytogenetic risk group yielded a significant continuous net reclassification improvement (0.718; 95%CI 0.353-1.082; P < 0.001). Decision curve analysis showed a clinical net benefit associated with adding G8 score to cytogenetic risk group. DISCUSSION: G8 score not only offered a strong prognostic factor for OS, but also markedly improved prediction accuracy for mortality when incorporated with cytogenetic risk group.

Postazacitidine clone size predicts long-term outcome of patients with myelodysplastic syndromes and related myeloid neoplasms.

Azacitidine is a mainstay of therapy for myelodysplastic syndrome (MDS)-related diseases. The purpose of our study is to elucidate the effect of gene mutations on hematological response and overall survival (OS), particularly focusing on their posttreatment clone size. We enrolled a total of 449 patients with MDS or related myeloid neoplasms. They were analyzed for gene mutations in pretreatment (n = 449) and posttreatment (n = 289) bone marrow samples using targeted-capture sequencing to assess the impact of gene mutations and their posttreatment clone size on treatment outcomes. In Cox proportional hazard modeling, multihit TP53 mutation (hazard ratio [HR], 2.03; 95% confidence interval [CI], 1.42-2.91; P < .001), EZH2 mutation (HR, 1.71; 95% CI, 1.14-2.54; P = .009), and DDX41 mutation (HR, 0.33; 95% CI, 0.17-0.62; P < .001), together with age, high-risk karyotypes, low platelets, and high blast counts, independently predicted OS. Posttreatment clone size accounting for all drivers significantly correlated with International Working Group (IWG) response (P < .001, using trend test), except for that of DDX41-mutated clones, which did not predict IWG response. Combined, IWG response and posttreatment clone size further improved the prediction of the original model and even that of a recently proposed molecular prediction model, the molecular International Prognostic Scoring System (IPSS-M; c-index, 0.653 vs 0.688; P < .001, using likelihood ratio test). In conclusion, evaluation of posttreatment clone size, together with the pretreatment mutational profile as well as the IWG response play a role in better prognostication of azacitidine-treated patients with myelodysplasia.

Prognostic value of metabolic tumor volume of extranodal involvement in diffuse large B cell lymphoma.

Extranodal involvement predicts poor outcomes of diffuse large B cell lymphoma (DLBCL), but the impact of the metabolic tumor burden (MTV) of extranodal sites using positron emission tomography has not been clarified. This study aimed to assess the impact of extranodal MTV on overall survival (OS). We retrospectively analyzed 145 newly diagnosed DLBCL patients and verified the prognostic impact of each extranodal and nodal MTV. Multivariate Cox hazards modelling using both extranodal and nodal MTV as covariables identified extranodal MTV as a significant factor for OS (hazard ratio [HR] 1.072, 95% confidence interval [CI] 1.019-1.129, P = 0.008), but not nodal MTV. Multivariate Cox modelling using restricted cubic splines demonstrated that the impact of total MTV depends on the MTV of extranodal sites, not of nodal sites. When both the number and MTV of extranodal involvements were used as covariables, extranodal MTV remained a significant predictor of OS (HR 1.070, 95%CI 1.017-1.127, P = 0.009), but the number of extranodal sites did not. Extranodal MTV potentially had a more significant role on prognosis than nodal MTV. When considering prognostic impacts, the MTV of extranodal involvement is significantly more important than the number.

Germ line DDX41 mutations define a unique subtype of myeloid neoplasms.

Germ line DDX41 variants have been implicated in late-onset myeloid neoplasms (MNs). Despite an increasing number of publications, many important features of DDX41-mutated MNs remain to be elucidated. Here we performed a comprehensive characterization of DDX41-mutated MNs, enrolling a total of 346 patients with DDX41 pathogenic/likely-pathogenic (P/LP) germ line variants and/or somatic mutations from 9082 MN patients, together with 525 first-degree relatives of DDX41-mutated and wild-type (WT) patients. P/LP DDX41 germ line variants explained ∼80% of known germ line predisposition to MNs in adults. These risk variants were 10-fold more enriched in Japanese MN cases (n = 4461) compared with the general population of Japan (n = 20 238). This enrichment of DDX41 risk alleles was much more prominent in male than female (20.7 vs 5.0). P/LP DDX41 variants conferred a large risk of developing MNs, which was negligible until 40 years of age but rapidly increased to 49% by 90 years of age. Patients with myelodysplastic syndromes (MDS) along with a DDX41-mutation rapidly progressed to acute myeloid leukemia (AML), which was however, confined to those having truncating variants. Comutation patterns at diagnosis and at progression to AML were substantially different between DDX41-mutated and WT cases, in which none of the comutations affected clinical outcomes. Even TP53 mutations made no exceptions and their dismal effect, including multihit allelic status, on survival was almost completely mitigated by the presence of DDX41 mutations. Finally, outcomes were not affected by the conventional risk stratifications including the revised/molecular International Prognostic Scoring System. Our findings establish that MDS with DDX41-mutation defines a unique subtype of MNs that is distinct from other MNs.

An unusual case of hepatosplenic T-cell lymphoma-like unclassifiable T/NK-cell lymphoma accompanied by acute myeloid leukemia.

We describe a case of unclassifiable T/NK-cell lymphoma with concomitant acute myeloid leukemia (AML). A 73-year-old Japanese man was diagnosed with AML by bone marrow smear, but the presence of splenomegaly and liver tumor was incompatible with AML. Splenectomy and hepatic resection were performed to resolve the thrombocytopenia and define the diagnosis. The pathological findings showed sinusoidal involvement of abnormal lymphoid cells that were CD3-positive but negative for T-cell receptor (TCR) rearrangement. Our case could not be categorized as hepatosplenic T-cell lymphoma because of the lack of immunohistological expression of TCR, despite the clinical similarity.

The Trajectory of the COVID-19 Vaccine Antibody Titers Over Time and the Association of Mycophenolate Mofetil in Solid Organ Transplant Recipients.

The COVID-19 vaccine will be safe and effective in solid organ transplant recipients (SOTs). However, the blunted antibody responses were also of concern. Few studies have reported prolonged serologic follow-up after 2 doses of BNT162b2 vaccine in SOTs. We performed a single-center, prospective observational study of 78 SOTs who received 2 doses of BNT162b2 vaccine. We identified the trajectory of antibody titers after vaccination among SOTs with or without mycophenolate mofetil (MMF) or withdrawn from MMF. We found low seroconversion rates (29/42: 69%) and low antibody titers in SOTs treated with MMF. An inverse linear relationship between neutralizing antibody titers and MMF concentration was confirmed in restricted cubic spline plots (P for effect < .01, P for nonlinearity = .08). For the trajectory of antibody responses, seroconversion and improved antibody titers were observed after withdrawal from MMF in SOTs who showed seronegative or low antibody titers at the first visit after 2 doses of vaccine (P for effect < .01, P for nonlinearity < .05, and P for interaction < .01). We identified increased B-cell counts after withdrawal from MMF (P < .01). The recovery of antibody responses was seen in SOTs withdrawn from MMF. The trajectories of antibody responses were modified by MMF administration.

Amplified EPOR/JAK2 Genes Define a Unique Subtype of Acute Erythroid Leukemia.

Acute erythroid leukemia (AEL) is a unique subtype of acute myeloid leukemia characterized by prominent erythroid proliferation whose molecular basis is poorly understood. To elucidate the underlying mechanism of erythroid proliferation, we analyzed 121 AEL using whole-genome, whole-exome, and/or targeted-capture sequencing, together with transcriptome analysis of 21 AEL samples. Combining publicly available sequencing data, we found a high frequency of gains and amplifications involving EPOR/JAK2 in TP53-mutated cases, particularly those having >80% erythroblasts designated as pure erythroid leukemia (10/13). These cases were frequently accompanied by gains and amplifications of ERG/ETS2 and associated with a very poor prognosis, even compared with other TP53-mutated AEL. In addition to activation of the STAT5 pathway, a common feature across all AEL cases, these AEL cases exhibited enhanced cell proliferation and heme metabolism and often showed high sensitivity to ruxolitinib in vitro and in xenograft models, highlighting a potential role of JAK2 inhibition in therapeutics of AEL. SIGNIFICANCE: This study reveals the major role of gains, amplifications, and mutations of EPOR and JAK2 in the pathogenesis of pure erythroleukemia. Their frequent response to ruxolitinib in patient-derived xenograft and cell culture models highlights a possible therapeutic role of JAK2 inhibition for erythroleukemia with EPOR/JAK2-involving lesions. This article is highlighted in the In This Issue feature, p. 369.

A multicenter phase II study of bendamustine, rituximab, and cytarabine (BRAC) for relapsed or refractory patients with follicular lymphoma or mantle cell lymphoma.

This phase II clinical trial aimed to evaluate the efficacy and safety of the combination therapy of bendamustine, cytarabine, and rituximab (BRAC) in patients with relapsed or refractory follicular lymphoma (FL) or mantle cell lymphoma (MCL). Thirteen patients were enrolled and received a median of 4 cycles (range 2-6) of BRAC. The complete response rate was 61.5%, and the overall response rate was 84.6%; the 2-year overall survival was 76.9%, and the 2-year progression-free survival was 69.2%. Although all patients received G-CSF prophylaxis, grade 3 or higher neutropenia was observed in all cycles, and the incidence of febrile neutropenia was 20%. Grade 4 thrombocytopenia was observed in 92.5% of all cycles, and platelet transfusion was performed in 94%. Although hematological toxicity was relatively high, BRAC therapy was effective for relapsed and refractory FL or MCL. Further studies are needed to determine the optimal dose of BRAC therapy.Trial registration The UMIN Clinical Trials Registry, UMIN000009797.

Hypocellular Philadelphia chromosome-positive mixed-phenotype acute leukemia successfully treated with dasatinib: A case report.

Both hypocellular leukemia and Philadelphia (Ph) chromosome-positive mixed-phenotype acute leukemia (MPAL) are rare subtypes of leukemia showing unfavorable outcomes and lacking established optimal management. Ph-positive leukemia most often presents with hypercellularity and hypoplasia is a rare condition. The present study reports an extremely rare case of hypocellular biclonal Ph-positive MPAL, which was diagnosed by biopsy and genetic analysis of bone marrow, and successfully treated with dasatinib and steroids. Briefly, a 77-year-old man presented with pancytopenia and flow cytometry of bone marrow could not be evaluated due to hypocellularity. The patient was finally diagnosed with hypocellular Ph-positive MPAL by genetic analysis and immunostaining of bone marrow biopsy. Although blood cells recovered with methylprednisolone pulse administration alone for concurrent optic neuritis, hematopoietic function rapidly normalized with dasatinib administered after definitive diagnosis of Ph-positive leukemia. Dasatinib and oral prednisolone were continued following methylprednisolone pulse administration and the patient achieved molecular complete remission (CR) on day 140 of treatment; molecular CR was maintained thereafter without any severe adverse events. In conclusion, the combination of dasatinib and a steroid may be one of the tolerable treatment options for elderly patients with hypocellular biclonal Ph-positive MPAL. Furthermore, genetic analysis and immunostaining of bone marrow biopsy can help with the diagnosis of leukemia with hypocellular bone marrow.

Clinical significance of oxidative stress for untreated patients with diffuse large B-cell lymphoma.

Oxidative stress serves an important role in carcinogenesis. The present study investigated the clinical significance of oxidative stress as a prognostic factor for diffuse large B-cell lymphoma (DLBCL). The participants comprised 55 consecutive patients with DLBCL. A commercially available derivatives of reactive oxygen metabolites (d-ROMs) test kit was used to assess oxidant levels. Similarly, a commercially available biological antioxidant potential (BAP) test was used to assess antioxidant levels. The antioxidative/oxidative stress ratio was calculated as d-ROMs/BAP. The median serum concentration of d-ROMs was 425 µM. The levels of d-ROMs were significantly higher in patients with DLBCL than in healthy volunteers (P<0.01). The complete remission (CR) rates in patients with d-ROMs <425 and ≥425 µM were 81.5 and 85.7%, respectively [not significant (NS)]. The 3-year overall survival (OS) rates for patients with d-ROMs <425 and ≥425 µM were 67.2 and 72.0%, respectively (NS). The median BAP was 2,002 µM. The CR rates of patients with BAP <2,002 and ≥2,002 µM were 77.8 and 88.9%, respectively (NS). The 3-year OS rates of patients with BAP <2,002 and ≥2,002 µM were 60.9 and 75.9%, respectively (NS). No significant difference in the d-ROMs/BAP ratio was observed between groups. Multivariate analysis revealed that d-ROMs were an independent prognostic factor for progression-free survival.

Prognostic impact of the controlling nutritional status score in patients with peripheral T-cell lymphoma.

The controlling nutritional status (CONUT) score is a simplified nutritional index calculated from serum albumin, total cholesterol, and total lymphocyte count. This study evaluated the prognostic impact of the CONUT score on overall survival (OS) in patients with peripheral T-cell lymphoma (PTCL). A multicenter, retrospective cohort study including 99 patients with PTCL was conducted. The CONUT score was significantly higher in the non-survivor group (median 5, range 0-12) than in the survivor group (median 3, range 0-11; p = 0.026). The CONUT score was an independent prognostic factor in a multivariable Cox proportional hazards model (hazard ratio 1.119, 95% confidence interval 1.021-1.227, p = 0.017). No significant effect-modification by the International Prognostic Index (IPI) was observed, and the CONUT score affected the prognosis of PTCL regardless of the IPI (P for interaction = 0.208). In conclusion, the CONUT score is an independent prognostic factor for PTCL irrespective of IPI category.
