Abstract Background Cancer Cachexia is a metabolic syndrome that can be present even in absence of weight loss and associated with significantly impaired survival. Muscle wasting represents a key-symptom of this syndrome and we recently demonstrated the strong prognosis impact of sarcopenia assessed by computed tomography (CT)-scan in diffuse large B-cell lymphoma (DLBCL) (Lanic et al. Leukemia & Lymphoma 2013). Conversely, the clinical relevance of loss of fat mass (adipopenia) remains unclear. The aim of this study was (i) to investigate the prognostic impact of a multidimensional tool combining a nutritional parameter (albuminemia) and body composition measurements (skeletal muscle and body fat composition) in elderly patients with DLBCL treated by chemotherapy and rituximab (R) (ii) to document the evolution of sarcopenia after immunochemotherapy. Methods This retrospective analysis included 80 DLBCL patients older than 70 years (y) and treated by R-CHOP or R-miniCHOP. Skeletal muscle (SM), visceral (V) and subcutaneal (S) adipose (A) tissues were measured by analysis of stored CT images at the Lumbar vertebrae 3 (L3) level. The surface of the muscular and adipose tissues was selected according to CT Hounsfield unit. Values were normalized for stature to calculate the L3 SM index (LSMI, in cm2/m2), the LVAI and the LSAI and used to define sarcopenia and visceral/subcutaneal adipopenia. Results The characteristics of the patients were as follows: median age = 78 y [70-95]; 36 males; IPI 0-2 = 22, 3-5 = 58; treatment by R-CHOP (n = 45) or R-miniCHOP (n = 35); median body mass index (BMI; in kg/m2) = 23.9. According to the sex-specific defined cut-offs for LSMI (< 55.8 cm²/m² for men and 38.9 cm²/m² for women), 44 DLBCL patients (55 %, 23 males) were considered as sarcopenic. With a median follow-up of 39 months, the 2y overall survival (OS) in the sarcopenic population was 46% as compared to 84% in the non-sarcopenic group (HR = 3.12; CI95%, 1.66-5.88; p=0.0004). The median LSAI was 76.3 cm2/m2 [10-167] in females and 47.4 cm2/m2[22-100] in males. The median LVSAI was 43.5 cm2/m2[3-141] in females and 50.4 cm2/m2[14-159] in males. Adipopenia, defined by a low LVAI and/or a low LSAI was also highly predictive of the outcome. The 2y OS of the low LVAI population was 48% as compared to 82% for the non-adipopenic group (HR = 2.20; CI95%, 1.19-4.05; p=0.01). The 2y OS in the low LSAI population was 48% as compared to 80% in the non-adipopenic group (HR = 2.28; CI95%, 1.23-4.21; p=0.008). A Three-point cachexia score (CS) including adipopenia, sarcopenia and hypo-albuminemia (defined by an albuminemia < 35 g/L) was build and delineates three distinct risk-groups (Figure 1). More importantly the CS remains predictive of the prognosis in a multivariate analysis including BMI (< or >= 25 kg/m2), age (< or >= 80y), IPI and gender (HR=2.5; CI95%= 1.14-5.39; p =0.02). LMSI was subsequently reassessed in thirty seven patients during the routine CT scan follow-up [mean = 10 months after pre-treatment CT scan (range 2.8-19.2)]. 15 (40%) patients displayed a 5% decrease of their LSMI, whereas 13 (35%) and 9 (25%) displayed no significant change or increase (>5%) of the LMSI respectively. Conclusion Our study demonstrates that sarcopenia and adipopenia estimated by CT-scan define cachexia more accurately than BMI or weight loss in elderly DLBCL patients. These factors can be integrated in a cachexia scoring tool which predicts the outcome independently of the BMI and of the IPI. CT scan follow-up indicates that cachexia is a reversible process that should be integrated as part of the therapeutic target in combination with lymphoma treatment. A prospective multicentric trial (registered as NCT01715961/Clinical.gov) is ongoing to validate these anthropometric and nutritional parameters and compare to geriatric assessment scales.

Diffuse Large B-Cell Lymphoma (DLBCL) is the most common lymphoid malignancy in adults, which often takes a nonlymph nodes organ as the primary focus. Primary lymphoid malignancy of thyroid gland is not common in clinic, EBV-positive primary diffuse large B-cell lymphoma of thyroid gland is rare in clinic, and its pathogenesis, treatment and prognosis are rarely studied. We reported an 85-year-old female patient with EBV-positive primary diffuse large B-cell lymphoma of thyroid gland, and the disease eventually relapsed in skeletal muscle of the patient. The pathological type after relapse was consistent with that of the primary focus. As far as we know secondary EBV-positive DLBCL of skeletal muscle from EBV-positive primary DLBCL of thyroid gland. For elderly patients with multiple adverse prognostic factors, individualized treatment on the premise of ensuring their quality of life may be more important.

Diffuse large B-cell lymphoma is extranodal in approximately 40% of cases, arising in nearly any organ system. DLBCL involvement of soft tissue and in particular skeletal muscle is extremely rare, comprising less than 1% of all extranodal non-Hodgkin lymphomas (NHL). We report a case of a 79-year-old man that presented with a DLBCL of the left triceps. In particular, we describe an unusual histologic appearance of pseudoglandular structures, resembling adenocarcinoma. We performed a review of lymphoma cases involving skeletal muscle diagnosed at our institution over the past 15 years as well as thorough PubMed review of the literature. We discuss the features of lymphoma involving skeletal muscle as it pertains to clinical characteristics, histologic subtype, tumor localization, diagnostic studies, therapy, and outcome. Finally, we highlight the diagnostic difficulties that can present in these rare and often challenging cases.

Baseline CT scans of 116 patients (48% female, median 64 years) with diffuse large B-cell lymphoma (DLBCL) were retrospectively reviewed to investigate the prognostic role of sarcopenia and fat compartment distributions on overall survival (OS), progression-free survival (PFS), and early therapy termination. Skeletal muscle index (SMI), skeletal muscle density (SMD), and intermuscular adipose tissue (IMAT) were quantified at the level of the third lumbar vertebra (L3) and proximal thigh (PT). Low L3-SMD, but not low L3-SMI, was associated with early therapy termination (p = 0.028), shorter OS (HR = 6.29; 95% CI = 2.17–18.26; p &lt; 0.001), and shorter PFS (HR = 2.42; 95% CI = 1.26–4.65; p = 0.008). After correction for sex, International Prognostic Index (IPI), BMI, and R-CHOP therapy (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone), low L3-SMD remained associated with poor OS (HR = 3.54; 95% CI = 1.10–11.40; p = 0.034) but not with PFS. Increased PT-IMAT was prognostic for poor OS and PFS after correction for sex, IPI, BMI, and R-CHOP therapy (HR = 1.35; CI = 1.03–1.7; p = 0.03, and HR = 1.30; CI = 1.04–1.64; p = 0.024, respectively). Reduced muscle quality (SMD) and increased intermuscular fat (IMAT), rather than low muscle quantity (SMI), are associated with poor prognosis in DLBCL, when measured at the L3 level, and particularly at the level of the proximal thigh. The proximal thigh represents a novel radiological landmark to study body composition.

Abstract Purpose: The tolerance of patients withdiffuse large B cell lymphoma（DLBCL） receiving CHOP±R regimen was significantly different, and grade 3~4 hematologic toxicity after chemotherapy in some patients resulted in prolonged hospital stay, increased risk of infection, delayed treatment, and directly or indirectly affected short-term efficacy and long-term prognosis. Lean body mass（LBM）and L3 skeletal muscle index （L3SMI）obtained from abdominal CT of DLBCL patients were analyzed to determine whether they could be used as independent predictors of hematological toxicity of CHOP± R regimen in DLBCL patients.Methods: The patients with DLBCL who underwent CHOP±R regimen at the Cancer Center of the First Hospital of Jilin University from January 2015 to November 2018 were retrospectively analyzed. The abdominal CT of the patient was analyzed by sliceOmatic5.0 software. The third lumbar disc planar imaging was selected, and two consecutive images were taken to calculate LBM and L3SMI. Single factor and multivariate analysis were performed on the correlation of LBM, L3SMIand chemotherapy-related grade 3~4 hematologic toxicity. The ROC curve was drawn to investigate the predictive value of various human indicators on the hematologic toxicity of grade 3~4 related to chemotherapy.Results: The L3 skeletal muscle index is associated with the occurrence of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. Those with lower L3SMI are prone to grade 3~4 hematologic toxicity.LBM is associated with the occurrence of grade 3~4 hematologic toxicity (leukopenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. This with lower LBM is prone to grade 3~4 hematologic toxicity.The L3 skeletal muscle index can be used as an independent predictor of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP ± R regimen. The cut-off value can be defined as 39.91 cm2/m2.Conclusion: We can draw the following conclusions:The L3 skeletal muscle index is associated with the occurrence of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. Those with lower L3SMI are prone to grade 3~4 hematologic toxicity.LBM is associated with the occurrence of grade 3~4 hematologic toxicity (leukopenia) in patients with diffuse large B-cell lymphoma treated with CHOP±R regimen. This with lower LBM is prone to grade 3~4 hematologic toxicity.The L3 skeletal muscle index can be used as an independent predictor of grade 3~4 hematologic toxicity (leukocyte and neutropenia) in patients with diffuse large B-cell lymphoma treated with CHOP ± R regimen. The cut-off value can be defined as 39.91 cm2/m 2.

Background: Our study measured the body composition of Diffuse large B-cell lymphoma (DLBCL) patients receiving rituximab with cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) regimen by computed tomographic (CT) and assessed their correlation with treatment-related toxicity and other adverse outcomes. Methods: We retrospectively analyzed 201 DLBCL patients who underwent pre-treatment abdominal CT examination. CT images were used to assess body composition metrics at the third lumbar vertebrae including fat tissues and muscle. Based on the skeletal muscle area (SMA) and density (SMD), skeletal muscle index (SMI), skeletal muscle gauge (SMG = SMI × SMD) and lean body mass (LBM) were calculated. Also analyzed were the toxicity, adverse events and survival. Results: We found that SMG, SMD, SMI and LBM were correlated with any grade 3–4 toxicity, dose reduction, hospitalization or termination of the treatment due to immunochemotherapy and worse survival. However, multivariate analysis demonstrated SMG [progression-free survival (PFS): hazard ratio (HR), 2.889; 95% CI, 1.401–5.959; p = 0.004; overall survival (OS): HR, 2.655; 95% CI, 1.218–5.787; p = 0.014] was the best predictor of poor prognosis. Conclusions: SMG, SMD, SMI and LBM were identified as predictors of adverse reactions and poor survival. SMG was an innovative and valuable indicator of immunochemotherapy toxicity and other adverse outcomes. Additionally, it can be used to individualize antineoplastic drug dosing.
