Loss of skeletal muscle mass during neoadjuvant treatments correlates with worse prognosis in esophageal cancer: a retrospective cohort study.

ABSTRACT: Nutritional deficits, cachexia, and sarcopenia are extremely common in esophageal cancer. The aim of this article was to assess the effect of loss of skeletal muscle mass during neoadjuvant treatment on the prognosis of esophageal cancer patients.Esophageal cancer patients (N = 115) undergoing neoadjuvant therapy and surgery between 2010 and 2014 were identified from our surgery database and retrospectively analyzed. Computed tomography imaging of the total cross-sectional muscle tissue measured at the third lumbar level defined the skeletal muscle index, which defined sarcopenia (SMI < 52.4 cm2/m2 for men and < 38.5 cm2/m2 for women). Images were collected before and after neoadjuvant treatments.Sarcopenia in preoperative imaging was prevalent in 92 patients (80%). Median overall survival was 900 days (interquartile range 334-1447) with no difference between sarcopenic (median = 900) and non-sarcopenic (median = 914) groups (p = 0.872). Complication rates did not differ (26.1% vs 32.6%, p = 0.725). A 2.98% decrease in skeletal muscle index during neoadjuvant treatment correlated with poor 2-year survival (log-rank p = 0.04).Loss of skeletal muscle tissue during neoadjuvant treatment correlates with worse overall survival.

Project description:BackgroundSarcopenia can contribute to negative outcomes in patients with various lung diseases. However, whether sarcopenia affects prognosis in patients with idiopathic pulmonary fibrosis (IPF) has not been reported. Simple measures of muscle mass, derived from chest computed tomography (CT), are increasingly being used to identify patients with sarcopenia. We hypothesized that skeletal muscle mass could be a predictor of prognosis in IPF patients.MethodsWe retrospectively evaluated 180 patients diagnosed with IPF between January 2010 and December 2015 at a tertiary care hospital in South Korea. We measured thoracic muscle volume by using the cross-sectional area (CSA) of the pectoralis, paraspinal, serratus, and latissimus muscles at the 4th vertebral region (T4CSA) and the erector spinae muscle (ESMCSA) at the 12th vertebral region. CT scans at the time of diagnosis were used for analysis and respective CSA were divided by height squared to normalize for stature. Survival times were estimated with the Kaplan-Meier method and compared with the log-rank test. Multivariate Cox proportional hazards models were performed to investigate relationships between clinical parameters and mortality.ResultsMale patients in the lowest quartile of T4CSA divided by height squared (m2) (T4MI) and in the lowest quartile of ESMCSA divided by height squared (m2) (T12MI) were more likely to have higher Gender-Age-Physiology Index scores (T4MI, 3.3 ± 1.3 vs 4.0 ± 1.6, P = 0.012; T12MI, 3.2 ± 1.3 vs 4.1 ± 1.6, P = 0.002). Male patients in the lowest quartile of T4MI exhibited a significantly lower survival rate (P = 0.035). After multivariate Cox proportional hazards analysis, T4MI was a significant risk factor for all-cause mortality (HR, 0.955; 95% CI, 0.913-0.998; P = 0.041), whereas T12MI was not (HR, 0.980; 95% CI, 0.856-1.121; P = 0.766).ConclusionsLow skeletal mass normalized for stature at the level of 4th vertebrae which can be acquired by quantifying thoracic skeletal muscle on single-slice axial chest CT, may be a strong risk factor for all-cause mortality in patients with IPF.Trial registrationThe research protocol was approved by the Institutional Review Board of Severance Hospital, South Korea (IRB No.4-2018-0454).

Project description:BackgroundObservational studies suggest that loss of skeletal muscle mass (SMM) is associated with chemotherapy-related toxicity, poor quality of life, and poor survival in metastatic colorectal cancer (mCRC) patients. Little is known about the evolution of SMM during palliative systemic therapy. We investigated changes in SMM during various consecutive palliative systemic treatment regimens using repeated abdominal computed tomography scans of mCRC patients who participated in the randomized phase 3 CAIRO3 study.MethodsIn the CAIRO3 study, mCRC patients with stable disease or better after 6 cycles of first-line treatment with capecitabine + oxaliplatin + bevacizumab (CAPOX-B) were randomized between maintenance treatment with capecitabine + bevacizumab (CAP-B) or observation. Upon first disease progression, in both groups, CAPOX-B or other treatment was reintroduced until the second disease progression, which was the primary study endpoint. We analysed 1355 computed tomography scans of 450 (81%) CAIRO3 patients (64 ± 9.0 years, CAP-B n = 223; observation n = 227) for SMM at four time points (i.e. prior to the start of pre-randomization initial treatment, at randomization, and at first and at second disease progression) using the Slice-o-matic software and single slice evaluation at the lumbar 3 level. By using accepted and widely used formulas, whole body SMM was calculated. A linear mixed effects model, adjusted for relevant confounders, was used to assess SMM changes for the total group and within and between study arms.ResultsDuring 6 cycles of initial treatment with CAPOX-B prior to randomization, SMM decreased significantly in all patients [CAP-B arm: -0.53 kg (95% CI -1.12; -0.07) and observation arm: -0.85 kg (-1.45; -0.25)]. After randomization, SMM recovered during CAP-B treatment by 1.32 kg (0.73; 1.90) and observation by 1.20 kg (0.63; 1.78) (median time from randomization to first disease progression 8.6 and 4.1 months for CAP-B arm and observation arm, respectively). After first progression and during reintroduction treatment with CAPOX-B or other treatment, SMM again decreased significantly and comparable in both arms, CAP-B: -2.71 kg (-3.37; -2.03), and observation: -2.01 kg (-2.64; -1.41) (median time from first progression until second progression CAP-B arm: 4.7 months and observation arm: 6.6 months).ConclusionsThis longitudinal study provides a unique insight in SMM changes in mCRC patients during palliative systemic treatment regimens, including observation. Our data show that muscle loss is reversible and may be influenced by the intensity of systemic regimens. Although studies have shown prognostic capacity for SMM, the effects of subsequent changes in SMM are unknown and may be clues for new future therapeutic interventions.
