Clinical usefulness of geriatric assessment in elderly patients with unresectable hepatocellular carcinoma receiving sorafenib or lenvatinib therapy.

BACKGROUND: Therapeutic strategies for unresectable hepatocellular carcinoma (u-HCC) in geriatric patients are important for real-world practice. However, there remain no established biomarkers or therapeutic strategies regarding the best second-line agent after atezolizumab plus bevacizumab therapy. AIM: In this study, we investigated the usefulness of modified Geriatric 8 (mG8) score in examining elderly patients (≥75 years old) with unresectable hepatocellular carcinoma (u-HCC) using sorafenib or lenvatinib as first-line therapy. METHODS AND RESULTS: This study assessed 101 elderly patients with u-HCC for their mG8 score (excluding elements of age from 8 items) and classified them into 2 groups according to their mG8 score: ≥11 as the high-score group and ≤ 10 as the low-score group. Among those taking sorafenib, no significant differences were noted in overall survival (OS) and progression free survival (PFS) between low and high mG8 score groups. Only modified albumin-bilirubin (ALBI) grade (2b/3 vs. 1/2a: HR 0.34; 95% CI, 0.17-0.69; p = .0029) was significantly associated with OS. Among those taking lenvatinib, patients with a high mG8 score (n = 26) had longer survival than those with a low mG8 score (n = 10) (20.0 months vs. 7.7 months: HR 0.31, 95% CI 0.11-0.89; p = .029). Intrahepatic tumor volume (<50% vs. ≥50%: HR 16.7; 95% CI, 1.71-163; p = .016) and α-fetoprotein (AFP) (<400 vs. ≥400: HR 3.38; 95% CI 0.84-19.7; p = .031) remained significant factors independently associated with OS. CONCLUSIONS: The mG8 score may contribute to making a decision when considering either sorafenib or lenvatinib as a treatment option for u-HCC in elderly patients.

Impact of pre-sarcopenia in sorafenib treatment for advanced hepatocellular carcinoma.

BACKGROUND: The present study aimed to investigate the impact of pre-sarcopenia on the prognosis of patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib. METHODS: We enrolled 214 patients (71 ± 10 years old; 166 men and 48 women; 90% Child-Pugh grade A and 10% Child-Pugh grade B) treated with sorafenib in our hospital from July 2009 to August 2016. The muscle volume was measured from CT images just before sorafenib administration using software (SliceOmatic). Skeletal muscle mass index was calculated, and the presence of pre-sarcopenia was judged according to the standard (42 cm2/m2 for men and 38 cm2/m2 for women) proposed by the Japan Society of Hepatology. RESULTS: Pre-sarcopenia was found in 123 patients (57%). The overall survival (OS) in patients with pre-sarcopenia tended to be worse than in patients without pre-sarcopenia (median 252 vs. 284 days, respectively; p = 0.16). Multivariate Cox hazard analysis revealed a baseline serum albumin level of ≤3.5 g/dl [hazard ratio (HR) 1.9; p = 0.0006], a baseline alpha-fetoprotein(AFP) level of ≥100 ng/ml (HR 2.1; p = 0.002), presence of lesions in bilateral hepatic lobes (HR 1.7; p = 0.03), and presence of major portal vein invasion (HR 1.8; p = 0.01) to be independent prognostic factors. In the 68 patients who had three or more negative prognostic factors, the presence of pre-sarcopenia did not correlate with prognosis. Of the 146 patients who had two or less prognostic factors, OS was significantly worse in 84 patients (58%) with pre-sarcopenia than in 62 patients without pre-sarcopenia (median 417 vs. 562 days, respectively; p = 0.047), and Cox hazard analysis revealed pre-sarcopenia to be an important prognostic factor (HR 1.6; p = 0.047). CONCLUSION: In sorafenib treatment for advanced HCC, pre-sarcopenia is a significant prognostic factor in patients with two or less negative prognostic factors, and could be the target of intervention to improve prognosis.

Premature Ovarian Insufficiency in Childhood Cancer Survivors: A Report From the St. Jude Lifetime Cohort.

Context: Long-term follow-up data on premature ovarian insufficiency (POI) in childhood cancer survivors are limited. Objective: To describe the prevalence of POI, its risk factors, and associated long-term adverse health outcomes. Design: Cross-sectional. Setting: The St. Jude Lifetime Cohort Study, an established cohort in a tertiary care center. Patients: Nine hundred twenty-one participants (median age, 31.7 years) were evaluated at a median of 24.0 years after cancer diagnosis. Main Outcome Measure: POI was defined by persistent amenorrhea combined with a follicle-stimulating hormone level >30 IU/L before age 40. Multivariable Cox regression was used to study associations between demographic or treatment-related risk factors and POI. Multivariable logistic regression was used to study associations between POI and markers for cardiovascular disease, bone mineral density (BMD), and frailty. Exposure to alkylating agents was quantified using the validated cyclophosphamide equivalent dose (CED). Results: The prevalence of POI was 10.9%. Independent risk factors for POI included ovarian radiotherapy at any dose and CED ≥8000 mg/m2. Patients with a body mass index ≥30 kg/m2 at the time of the St. Jude Lifetime Cohort assessment were less likely to have a diagnosis of POI. Low BMD and frailty were independently associated with POI. Conclusion: High-dose alkylating agents and ovarian radiotherapy at any dose are associated with POI. Patients at the highest risk should be offered fertility preservation whenever feasible. POI contributes to poor general health outcomes in childhood cancer survivors; further studies are needed to investigate the role of sex hormone replacement in improving such outcomes.

Changes in plasma vascular endothelial growth factor at 8 weeks after sorafenib administration as predictors of survival for advanced hepatocellular carcinoma.

BACKGROUND: A new predictive biomarker for determining prognosis in patients with hepatocellular carcinoma (HCC) who receive sorafenib is required, because achieving a reduction in tumor size with sorafenib is rare, even in patients who have a favorable prognosis. Vascular endothelial growth factor (VEGF) receptor is a sorafenib target. In the current study, the authors examined changes in plasma VEGF concentrations during sorafenib treatment and determined the clinical significance of VEGF as a prognostic indicator in patients with HCC. METHODS: Plasma VEGF concentrations were serially measured in 63 patients with advanced HCC before and during sorafenib treatment. A plasma VEGF concentration that decreased >5% from the pretreatment level at 8 weeks was defined as a "VEGF decrease." An objective tumor response was determined using modified Response Evaluation Criteria in Solid Tumors 1 month after the initiation of therapy and every 3 months thereafter. RESULTS: Patients who had a VEGF decrease at week 8 (n=14) had a longer median survival than those who did not have a VEGF decrease (n=49; 30.9 months vs 14.4 months; P=.038). All patients who had a VEGF decrease survived for >6 months, and the patients who had both a VEGF decrease and an α-fetoprotein response (n=6) survived during the observation period (median, 19.7 months; range, 6.5-31.0 months). In univariate analyses, a VEGF decrease, radiologic findings classified as progressive disease, and major vascular invasion were associated significantly with 1-year survival; and, in multivariate analysis, a VEGF decrease was identified as an independent factor associated significantly with survival. CONCLUSIONS: A plasma VEGF concentration decrease at 8 weeks after starting sorafenib treatment may predict favorable overall survival in patients with advanced HCC.

Systematic reviews of TCM trials: how does inclusion of Chinese trials affect outcome?

AIM: Systematic reviews (SRs) are an important tool for the synthesis of research and are used to guide both research and clinical practice. Previous research suggests that changes to standard SR methodology may be warranted. The objectives of this study were to determine the value of adding Chinese-language databases to conventional systematic review (SR) search strategies, and ii) to determine the importance of methodological validation of TCM RCTs in the conduct of SRs of two health conditions, chronic fatigue syndrome (CFS) and EBV-infectious mononucleosis (mono). METHODS: Ten English-language and two Chinese-language databases were searched from inception to 2008. After initial screening potentially relevant publications were retrieved and assessed based on predetermined inclusion criteria. Method of randomization was verified using author interviews. RESULTS: Mono Search - While English-language database searches did not yield any potentially relevant references, Chinese-language database searches identified 14 studies labelled as RCTs. Author interview determined that 10 were clinical summaries and one a controlled clinical trial. Authors for three publications were unavailable. CFS Search - English-language and Chinese-language database searches identified 8 and 28 potentially relevant references, respectively, for a total of 36, however, none met all inclusion criteria. CONCLUSIONS: Utilization of Chinese-language databases greatly increased the number of potentially relevant references for each search. Unfortunately, due to methodological flaws, this additional information did not generate any usable information. Medical research in China continues to be active, including the conduct of RCTs, however, improvements in trial design and conduct in medical research in China are essential in order for this material to be useful in guiding research and practice.

The safety of pediatric acupuncture: a systematic review.

CONTEXT: Acupuncture is increasingly used in children; however, the safety of pediatric acupuncture has yet to be reported from systematic review. OBJECTIVE: To identify adverse events (AEs) associated with needle acupuncture in children. METHODS: Eighteen databases were searched, from inception to September 2010, irrespective of language. Inclusion criteria were that the study (1) was original peer-reviewed research, (2) included children from birth to 17 years, inclusively, (3) involved needle acupuncture, and (4) included assessment of AEs in a child. Safety data were extracted from all included studies. RESULTS: Of 9537 references identified, 450 were assessed for inclusion. Twenty-eight reports were included, and searches of reference lists identified 9 additional reports (total: 37). A total of 279 AEs were identified, 146 from randomized controlled trials, 95 from cohort studies, and 38 from case reports/series. Of the AEs, 25 were serious (12 cases of thumb deformity, 5 infections, and 1 case each of cardiac rupture, pneumothorax, nerve impairment, subarachnoid hemorrhage, intestinal obstruction, hemoptysis, reversible coma, and overnight hospitalization), 1 was moderate (infection), and 253 were mild. The mild AEs included pain, bruising, bleeding, and worsening of symptoms. We calculated a mild AE incidence per patient of 168 in 1422 patients (11.8% [95% confidence interval: 10.1-13.5]). CONCLUSIONS: Of the AEs associated with pediatric needle acupuncture, a majority of them were mild in severity. Many of the serious AEs might have been caused by substandard practice. Our results support those from adult studies, which have found that acupuncture is safe when performed by appropriately trained practitioners.

Early decrease in α-fetoprotein, but not des-γ-carboxy prothrombin, predicts sorafenib efficacy in patients with advanced hepatocellular carcinoma.

OBJECTIVES: The aim of this study was to investigate the relationships between early changes in the tumor markers α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP), and antitumor response in the early period following administration of sorafenib in patients with advanced hepatocellular carcinoma (HCC). METHODS: Forty-eight advanced HCC patients were evaluated. AFP and DCP were measured at baseline, and after 2 and 4 weeks, and the antitumor responses were evaluated according to the RECIST criteria 4 weeks after starting sorafenib therapy. The ratios of each tumor marker were compared by stratifying the patients into the partial response (PR) + stable disease (SD) group or the progressive disease (PD) group. RESULTS: Both 2 and 4 weeks after starting sorafenib therapy, the AFP ratio in the PR + SD group (n = 32) was significantly lower than in the PD group (n = 16; p = 0.002, p = 0.002). DCP was elevated in both the PR + SD group and the PD group 2 weeks and 4 weeks after starting sorafenib therapy. CONCLUSIONS: Evaluation of AFP ratios 2 and 4 weeks after starting sorafenib therapy may be useful for predicting antitumor response. On the other hand, early elevation of DCP does not necessarily suggest treatment failure by sorafenib, as DCP elevation can occur despite therapeutic efficacy.

Cruciferous vegetable supplementation in a controlled diet study alters the serum peptidome in a GSTM1-genotype dependent manner.

BACKGROUND: Cruciferous vegetable intake is inversely associated with the risk of several cancers. Isothiocyanates (ITC) are hypothesized to be the major bioactive constituents contributing to these cancer-preventive effects. The polymorphic glutathione-S-transferase (GST) gene family encodes several enzymes which catalyze ITC degradation in vivo. METHODS: We utilized high throughput proteomics methods to examine how human serum peptides (the "peptidome") change in response to cruciferous vegetable feeding in individuals of different GSTM1 genotypes. In two randomized, crossover, controlled feeding studies (EAT and 2EAT) participants consumed a fruit- and vegetable-free basal diet and the basal diet supplemented with cruciferous vegetables. Serum samples collected at the end of the feeding period were fractionated and matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry spectra were obtained. Peak identification/alignment computer algorithms and mixed effects models were used to analyze the data. RESULTS: After analysis of spectra from EAT participants, 24 distinct peaks showed statistically significant differences associated with cruciferous vegetable intake. Twenty of these peaks were driven by their GSTM1 genotype (i.e., GSTM1+ or GSTM1- null). When data from EAT and 2EAT participants were compared by joint processing of spectra to align a common set, 6 peaks showed consistent changes in both studies in a genotype-dependent manner. The peaks at 6700 m/z and 9565 m/z were identified as an isoform of transthyretin (TTR) and a fragment of zinc α2-glycoprotein (ZAG), respectively. CONCLUSIONS: Cruciferous vegetable intake in GSTM1+ individuals led to changes in circulating levels of several peptides/proteins, including TTR and a fragment of ZAG. TTR is a known marker of nutritional status and ZAG is an adipokine that plays a role in lipid mobilization. The results of this study present evidence that the GSTM1-genotype modulates the physiological response to cruciferous vegetable intake.

Associations between healthy eating patterns and immune function or inflammation in overweight or obese postmenopausal women.

BACKGROUND: The link between poor nutritional status and impaired immune function is well established; however, most studies have focused on individual nutrients instead of overall dietary patterns. OBJECTIVE: Our objective was to investigate associations between 3 indexes of overall diet quality [the Diet Quality Index (DQI), the DQI including supplementary calcium (DQI-Ca), and the Healthy Eating Index (HEI)] and biomarkers of inflammation and immunity. DESIGN: This cross-sectional study included 110 overweight or obese postmenopausal women. Dietary intake measured by food-frequency questionnaire was used to calculate diet quality scores. C-reactive protein (CRP) and serum amyloid A (SAA) were measured by latex-enhanced nephelometry. Flow cytometry was used to measure natural killer (NK) cell cytotoxicity and to enumerate and phenotype lymphocyte subsets. T lymphocyte proliferation was assessed by (3)H-thymidine incorporation as well as by the carboxyfluorescein-succinimidyl ester method of cell division tracking. Multivariable-adjusted linear regression analysis was used to investigate associations between diet quality scores and markers of inflammation and immune function. RESULTS: Higher diet quality was associated with increased proportions of cytotoxic and decreased proportions of helper T lymphocytes. CRP and SAA concentrations were higher among women with a lower-quality diet; these associations became nonsignificant after adjustment for body mass index or percentage body fat. We observed limited evidence for an association between healthy eating patterns and greater lymphocyte proliferation and no evidence for an association with NK cell cytotoxicity. CONCLUSION: Our results provide limited evidence that healthy eating patterns contribute to enhanced immune function and reduced inflammation in overweight and obese postmenopausal women.

Unmetabolized folic acid in plasma is associated with reduced natural killer cell cytotoxicity among postmenopausal women.

Folic acid (FA) supplements and food fortification are used to prevent neural tube defects and to lower plasma homocysteine. Through exposure to food fortification and vitamin supplement use, large populations in the United States and elsewhere have an unprecedented high FA intake. We evaluated dietary and supplemental intakes of folate and FA in relation to an index of immune function, natural killer cell (NK) cytotoxicity, among 105 healthy, postmenopausal women. Among women with a diet low in folate (<233 microg/d), those who used FA-containing supplements had significantly greater NK cytotoxicity (P = 0.01). However, those who consumed a folate-rich diet and in addition used FA supplements > 400 microg/d had reduced NK cytotoxicity compared with those consuming a low-folate diet and no supplements (P = 0.02). Prompted by this observation, we assessed the presence of unmetabolized FA in plasma as a biochemical marker of excess FA. Unmetabolized folic acid was detected in 78% of plasma samples from fasting participants. We found an inverse relation between the presence of unmetabolized FA in plasma and NK cytotoxicity. NK cytotoxicity was approximately 23% lower among women with detectable folic acid (P = 0.04). This inverse relation was stronger among women >or= 60 y old and more pronounced with increasing unmetabolized FA concentrations (P-trend = 0.002). Because of the increased intake of FA in many countries, our findings highlight the need for further studies on the effect of long-term high FA intake on immune function and health.

Associations between reproductive and menstrual factors and postmenopausal androgen concentrations.

BACKGROUND: Reproductive and menstrual characteristics, as well as high circulating estrogen and androgen concentrations, are associated with the risk of breast and ovarian cancer in postmenopausal women. To explore possible etiological relationships between menstrual and reproductive characteristics and cancer risk, we examined associations between menstrual and reproductive factors and serum concentrations of total testosterone, free testosterone, androstenedione, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEA-S). METHODS: This study was conducted in 167 postmenopausal women, using data from the pre-randomization visit of an exercise clinical trial. Participants were sedentary, overweight/ obese, and not on hormone therapy. RESULTS: DHEA-S concentrations were 42% higher, total testosterone concentrations were 35% lower, and free testosterone concentrations were 23% lower in women with both ovaries removed compared with those with both remaining (p = 0.01, p = 0.01, and p = 0.03, respectively). Women who had used herbal therapy in the past had, on average, 25% higher concentrations of total and free testosterone than women who had never used these herbal therapies (p = 0.03 and p = 0.004, respectively). No other significant associations were detected. CONCLUSIONS: Overall, this study does not support the hypothesis that reproductive or menstrual factors, with the exception of oophorectomy status, are associated with postmenopausal androgen concentrations.
