levoleucovorin and Sarcopenia

Sarcopenia, defined as decrease in skeletal muscle mass (SMM) and strength, might be associated with reduced survival. We investigated the impact of sarcopenia and decrease in SMM in patients with advanced pancreatic cancer during FOLFIRINOX (FX) therapy. Consecutive sixty-nine patients who received FX were evaluated. Skeletal muscle index (SMI) (cm2/m2) was used to evaluate SMM. The cut-off value of sarcopenia was defined as SMI <42 for males and <38 for females, based on the Asian Working Group for sarcopenia criteria. Sarcopenia was diagnosed in thirty-three (48 %) subjects. Comparison of baseline characteristics of the two groups (sarcopenia group: non-sarcopenia group) showed a significant difference in sex, tumour size and BMI. There was no significant difference in the incidence of adverse events with grades 3-5 and progression-free survival (PFS) during FX between the two groups (PFS 8·1 and 8·8 months; P = 0·88). On the multivariate analysis, progressive disease at the first follow-up computed tomography (hazard ratio (HR) 3·87, 95 % CI 1·53, 9·67), decreased SMI ≥ 7·9 % in 2 months (HR 4·02, 95 % CI 1·87, 8·97) and carcinoembryonic antigen ≥ 4·6 (HR 2·52, 95 % CI 1·10, 6·11) were significant risk factors associated with poor overall survival (OS), but sarcopenia at diagnosis was not. OS in patients with decreased SMI of ≥7·9 % and <7·9 % were 10·9 and 21·0 months (P < 0·01), respectively. In conclusion, decrease in SMM within 2 months after the initiation of chemotherapy had significantly shorter OS, although sarcopenia at diagnosis did not affect OS. Therefore, it might be important to maintain SMM during chemotherapy for a better prognosis.

The impact of the new chemotherapy, fluorouracil plus leucovorin, oxaliplatin, and docetaxel (FLOT) on body composition in gastric cancer (GC) patients remains unknown. We assessed body composition changes of GC patients receiving the FLOT regimen and their impact on treatment outcomes.. Preoperative pre- and post-FLOT computed tomography (CT) scans of advanced GC patients were studied. Lumbar skeletal muscle index (SMI) and adipose indices were calculated before and after FLOT.. A total of 26 patients were identified between April 2019 and January 2020. Nineteen patients were sarcopenic at diagnosis. The mean BMI decreased (from 24.4 ± 3.7 to 22.6 ± 3.1;. Almost three-quarters (73.1%) of GC patients were sarcopenic at diagnosis. Preoperative FLOT was associated with a further reduction in SMI, BMI, and VAI. These changes were not associated with short-term outcomes.

FOLFIRINOX is the reliable treatments for pancreatic cancer, but it has a relatively high toxicity and the selection of suitable patients for this regimen remains challenge. On the other hand, sarcopenia is one of the important prognostic factors of pancreatic cancer. The aim of this study was to investigate the effect of sarcopenia on overall survival (OS) and time to treatment failure (TTF) in patients with pancreatic cancer who received FOLFIRINOX.. Clinical data of consecutive patients treated with FOLFIRINOX at our institution from 2011 to 2017 was retrospectively reviewed. Skeletal muscle index (SMI) and adipose tissue index (ATI) at the third lumbar spine level was calculated from computed tomography (CT) images. The association between clinical factors (SMI and ATI), and OS and TTF were determined using univariate and multivariate analyses.. We assessed 82 patients. The median OS of sarcopenia and the non-sarcopenia patients were 11.3 and 17.0 months, respectively (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.43-4.32; p = 0.001). Median TTF was 3.0 and 6.1 months in the sarcopenia and the non-sarcopenia patients, respectively (HR, 1.67; 95% CI, 1.03-2.71; p = 0.032). Multivariate analyses revealed that sarcopenia (HR, 1.37; 95% CI, 1.01-1.87; p = 0.045) was an independent prognostic factor of OS. High ATI (p = 0.022) and sarcopenic obesity (p = 0.008) were significantly associated with hematologic toxicity.. Sarcopenia is an independent indicator of poor prognosis in patients with pancreatic cancer who received FOLFIRINOX, while ATI and sarcopenic obesity predicted severe hematologic toxicity.

Sarcopenia, the presence of skeletal muscle mass depletion, can be objectively quantified, whereas subjective global assessment (SGA) is a widely utilized subjective instrument to assess nutritional status. Both the presence of sarcopenia and SGA-assessed malnutrition, in isolation, have been shown to be associated with worse overall survival in a wide range of cancers. However, there is no research evaluating the independent prognostic significance of both the presence of sarcopenia and malnutrition as part of the same analysis. We investigated the impact of sarcopenia on overall survival in colorectal cancer specifically controlling for malnutrition.. We examined a consecutive case series of 112 patients with colorectal cancer first seen at our institution between August 2012 and October 2017. Using computed tomography (CT) imaging, the cross-sectional area of muscles at the L3 vertebral level was measured and then divided by height squared to calculate skeletal muscle index (SMI). Sarcopenia was defined as SMI ≤38.5 cm2/m2 for women and ≤52.4 cm2/m2 for men. SGA assessments were completed within 2 weeks of CT imaging. The association of sarcopenia and malnutrition with overall survival was assessed using univariate and multivariate Cox regression analysis.. Median age at presentation was 53.3 years. Sixty-six (58.9%) patients had metastatic disease at diagnosis. Using SMI, 46 (41.1%) patients were sarcopenic, while 66 (58.9%) were non-sarcopenic. Using SGA, 69 (61.6%) patients were assessed as well-nourished, while 43 (38.4%) were malnourished. Of 69 patients classified as well-nourished by SGA, 22 (31.9%) were sarcopenic. Similarly, of 43 patients categorized as malnourished by SGA, 19 (44.2%) were non-sarcopenic. On multivariate analysis, after adjusting for age, gender, tumor stage, BMI, treatment history and SGA, patients with sarcopenia had 3 times greater risk of mortality compared to those without sarcopenia (p = 0.001). The median survival of patients with both sarcopenia and malnutrition (n = 24) was 14.6 months (95% CI: 10.5 to 18.6) compared to the median survival of 25.9 months (95% CI: 7.8 to 44.0) in patients who were either sarcopenic or malnourished but not both (n = 41; p = 0.001). The median survival of patients who were non-sarcopenic and well nourished (n = 48; p = 0.001) was 38.6 months (95% CI: 25.6 to 51.6).. The exploratory study suggests that presence of sarcopenia supersedes the presence of malnutrition as a predictor of survival in colorectal cancer. Co-existence of sarcopenia and malnutrition is associated with worse survival in colorectal cancer compared to just one of those conditions being present. Prospective studies with large sample sizes are needed to confirm these findings.

Great heterogeneity exists in the ability of adults with cancer to tolerate chemotherapy. Variability in body composition may affect rates of metabolism of cytotoxic agents and contribute to the variable chemotherapy toxicity observed. The objective of this exploratory study was to examine the association of low skeletal muscle, commonly known as sarcopenia, on the pharmacokinetics (PKs) of 5-fluorouracil (5FU) in patients receiving FOLFOX for colorectal cancer.. We performed a secondary analysis of a completed multicenter trial that investigated PK-guided 5FU dosing in patients receiving mFOLFOX6 +/- bevacizumab for colorectal cancer. Cycle 1 PK samples were obtained 2-44 h after the start of the 5FU infusion (steady state).. No significant differences in first cycle 5FU area-under-the-concentration-time-curve (AUC) were found between sarcopenic and non-sarcopenic patients (17.3 vs. 19.3 AUC, p = 0.43). Patients with grade 3/4 toxicity had a higher dose of 5FU per kg lean body mass (LBM) (105 vs. 93 mg/kg, p = 0.06), most notably for hematological toxicities (110 vs. 94 mg/kg, p = 0.002); however, no correlation between the dose/LBM and 5FU AUC was found.. Although our results did not confirm the impact of low skeletal muscle on PKs of 5FU, further research exploring the impact of body composition on chemotherapy PKs and related toxicities is warranted with the potential for alternative dosing strategies in sarcopenic patients to reduce unnecessary toxicities while maintaining efficacy.

Despite the positive survival results of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), criticisms have been put forward regarding the safety of this treatment as a result of a high morbidity rate. Muscle depletion (sarcopenia) is associated with the occurrence of postoperative complications. The purpose of this study was to determine the association between sarcopenia and postoperative morbidity after CRS-HIPEC for peritoneal carcinomatosis from colorectal cancer by distinguishing the complications linked to CRS itself and those associated with chemotherapy (HIPEC) toxicities.. Data concerning 97 consecutive patients who had undergone CRS-HIPEC were recorded. We analyzed the events occurring within 30 days after surgery that were prospectively recorded in a database. Sarcopenia was assessed using the L3 muscle index on computed tomography performed during the 2 months preceding surgery.. The sarcopenic patients experienced significantly more chemotherapy toxicities (57 vs. 26 %; p = 0.004) and especially neutropenia (36 vs. 17 %; p = 0.04) than their nonsarcopenic counterparts. There was no difference in complications linked to the CRS procedure between sarcopenic and nonsarcopenic patients. In the multivariate analysis, sarcopenia was the only parameter independently associated with the risk of chemotherapy toxicity (odds ratio 3.97; 95 % confidence interval 1.52-10.39; p = 0.005).. Despite the local administration of chemotherapy, systemic toxicity was observed in sarcopenic patients after CRS-HIPEC. This relationship favors new treatment strategies with white blood cell growth factors or chemotherapy dosing based on muscle value.

The purpose of this study was to elucidate the effect of decreased muscle mass on the toxicity and survival of patients with colon cancer treated with adjuvant chemotherapy after surgery.. We reviewed the data of 229 consecutive patients with stage III colon cancer who received adjuvant oxaliplatin, 5-fluorouracil, and leucovorin chemotherapy at a single center between 2003 and 2010. Baseline muscle mass was assessed by measuring the cross-sectional area of the psoas muscle at the level of the fourth lumbar vertebra on computed tomography images. Effects of muscle mass on toxicity of chemotherapy and survival were assessed.. The median age of the 229 patients was 61 years (range, 28-80) and 134 (58.5 %) were men. The mean psoas muscle mass index (PI, psoas muscle area divided by height(2) [mm(2)/m(2)]) was 548.3. A 1 SD decrement in the PI was associated with an increase in all grade 3-4 toxicities in univariate (OR = 1.69, 95 % CI = 1.18-2.27) and multivariate (OR = 1.56, 95 % CI = 1.05-2.38) analyses. In univariate analysis, the PI was not associated with overall survival. However, multivariate analysis showed that a 1 SD decrement in the PI increased the hazard of overall mortality by 85 % (HR = 1.85, 95 % CI = 1.10-3.13). This effect of the PI on mortality was maintained in subgroup analyses, especially in older and obese patients.. Decreased muscle mass was associated with increased risk of grade 3-4 toxicity and poor prognosis in patients with stage III colon cancer.

The association between body composition parameters and toxicity from hepatic arterial infusion (HAI) chemotherapy regimens has not been analyzed. We assessed data from patients with advanced cancer and liver metastases treated on a clinical trial of a regimen of HAI oxaliplatin combined with systemic 5-fluorouracil/leucovorin and bevacizumab. Correlations between patient characteristics, response, and toxicity and body composition data taken from CT images were analyzed. Forty-eight of 57 patients (mean age 56 yr; 60% women) had available CT scans. The most common diagnosis was colorectal cancer (22/48, 46%); 30/48 patients (63%) had body mass index (BMI) ≥25 kg/m(2). Twenty (42%) of 48 patients were sarcopenic. Grade 3-4 adverse events did not differ among patients with and without sarcopenia or according to BMI. The median survival (95% C]) was 167 (128-206) days for sarcopenic and 280 (214-346) days for nonsarcopenic patients (P = 0.271). Among patients treated at the maximum tolerated dose, the median survival was 103 days for sarcopenic and 312 days for nonsarcopenic patients (P = 0.173). Sarcopenia was present in 30% (6/20) of patients with reduction in tumor size posttreatment, and in 52% (14/27) of patients with increased tumor size (P = 0.171). In conclusion, body composition was not significantly associated with toxicities or survival in our small sample.
