Abstract
Ankle sprain (AS) is the most common sports injury that can be complicated by chronic joint instability. The aim of this study was to examine the relationship between foot types and the ankle sprain events suffered during the sport career in female volleyball players. In this retrospective study, we randomly selected 98 female volleyball players competing in several divisions. Data were obtained from self-administered questionnaires in which the athlete noted data about volleyball practice, whether they had had ankle sprains and the number of these events. Plantar footprint was photographed by a plantoscope classifying each foot as normal, flat or cavus (196 feet). Of the 196 feet, 145 (74.0%) were normal, 8 (4.1%) were flat 43 and (21.9%) were cavus. Thirthy-five athletes reported at least one AS during volleyball practice. In total 65 sprain injuries were reported (35 to the right side and 30 to the left side). In 22 ankles (14 right, 8 left) sprain reinjure (AS >1) have been reported. A higher AS reinjury rate is correlated to the cavus footprint pattern (p = 0,005). Cavus foot associates to a higher risk of reinjury for ankle sprains in female volleyball players. Knowing the athletes which are more likely to sustain a reinjure may be helpful for the orthopedic surgeon to plan preventive strategies.

One year of surgical mask testing at the University of Bologna labs: Lessons learned from data analysis. Sep Purif Technol 2022; 294:121180.

Abstract
The outbreak of SARS-CoV-2 pandemic highlighted the worldwide lack of surgical masks and personal protective equipment, which represent the main defense available against respiratory diseases as COVID-19. At the time, masks shortage was dramatic in Italy, the first European country seriously hit by the pandemic: aiming to address the emergency and to support the Italian industrial reconversion to the production of surgical masks, a multidisciplinary team of the University of Bologna organized a laboratory to test surgical masks according to European regulations. The group, driven by the expertise of chemical engineers, microbiologists, and occupational physicians, set-up the test lines to perform all the functional tests required. The laboratory started its activity on late March 2020, and as of the end of December of the same year 435 surgical mask prototypes were tested, with only 42 masks compliant to the European standard. From the analysis of the materials used, as well as of the production methods, it was found that a compliant surgical mask is most likely composed of three layers, a central meltblown filtration layer and two external spunbond comfort layers. An increase in the material thickness (grammage), or in the number of layers, does not improve the filtration efficiency, but leads to poor breathability, indicating that filtration depends not only on pure size exclusion, but other mechanisms are taking place (driven by electrostatic charge). The study critically reviewed the European standard procedures, identifying the weak aspects; among the others, the control of aerosol droplet size during the bacterial filtration test results to be crucial, since it can change the classification of a mask when its performance lies near to the limiting values of 95 or 98%.

Abstract
BACKGROUND immune checkpoint inhibitors(ICIs) have shown contradictory results in patients with advanced gastro-oesophageal junction/gastric cancer(GOJ/GC). AIM to identify specific patient subgroups that would derive survival benefit from ICIs. METHODS a subgroup meta-analysis of randomised clinical trials(RCTs) was carried out. RESULTS four phase-III-RCTs were identified with data on the following variables: primary location(Gastric vs GOJ); age(≤ 65 vs >65); gender(male vs female); ECOG PS(0 vs 1); ethnicity (Asian vs non-Asian), histology(intestinal vs diffuse), PD-L1 expression(≥ 1% vs < 1%). PD-L1 positivity was significantly associated with survival benefit from ICIs (HR: 0.82, p 0.047), with a significant interaction between PD-L1 expression and ICI efficacy (interaction HR: 1.41, p 0.02). Numerically, the second most relevant interaction was ICI efficacy and gender, with ICI being more effective in males. CONCLUSION The PD-L1 positive patient subgroup derives significant survival benefit from ICI in GOJ/GC, however other predictors are eagerly needed to further refine patient selection.

Abstract
Aims and Background Rarely are conclusions from clinical trials summarized in international consensus conferences and promptly transferred to patient care. The adjuvant therapy for colorectal cancer used in daily clinical practice in Italy is described and compared with the recommendations of the 1990 NIH Consensus Conference. Patients and Methods We audited prescriptions of adjuvant systemic therapies for Italian colorectal cancer patients in 82 centers during a fixed one-week period. Results Among 434 patients receiving adjuvant chemotherapy there were 139 (42.5%) colon cancer patients with N- and 169 (51.7%) with N+ regional nodal involvement. Treatment at academic centers, a young age, T4 and a low total number of lymph nodes removed at surgery were the factors potentially justifying the decision for adjuvant chemotherapy in stage II colon cancer patients. The most common chemotherapy used was a bolus of 5-fluorouracil/folinic acid for 6 months (75.8%). Adjuvant radiotherapy was not administered to 37 (38.5%) of 96 patients with stage II and III rectal cancer. Conclusions The study shows that a substantial proportion of patients on adjuvant treatment at a certain time point in a large enough sample of Italian centers are stage II (potential over-treatment) and that an under-treatment of stage II and III rectal cancer patients (lack of radiotherapy) occurs too often in daily clinical practice in this country.

Abstract
Aims and Background In the last ten years validation of the sentinel lymph node (SLN) concept has led to modification of the surgical approach for patients with intermediate-risk cutaneous melanoma. Methods and Study Design Forty-eight patients affected by cutaneous melanoma with a Breslow thickness between 0.65 and 4 mm were enrolled in the study. Approximately 2 mCi of radiotracer and 1 mL of vital blue dye were injected in each patient around the site of the primary lesion. Lymphoscintigraphy was performed until the lymphatic basin and the respective SLN were localized. The whole surgical procedure consisted of enlargement of the surgical margins followed by localization and excision of the SLN(s) by using both radiotracer and vital dye. Whenever the SLN proved to be histologically positive for metastasis, complete regional lymphadenectomy was performed. Results Within 15 minutes of radiotracer administration the lymphatic basin was localized in all 48 patients by lymphoscintigraphy. Vital dye and radiotracer successfully allowed SLN localization and excision in 46 of 48 patients (97%); in one case the SLN was detected by radiotracer alone. The SLN proved to be metastatic in six (13%) of 46 evaluable patients; interestingly, in three of them the presence of metastatic cells was revealed only by immunohistochemistry. All patients with tumor-positive SLNs had primary lesions with a Breslow thickness = 2 mm. Conclusions Sentinel lymphadenectomy is able to identify lymph node involvement in patients with cutaneous melanoma with a Breslow thickness >1 mm, thus avoiding the risks associated with radical regional lymphadenectomy. Lymphoscintigraphy proved to be an important tool to obtain correct preoperative localization of the drainage basin, especially for melanomas located on the face and trunk.

Abstract
Aims and Background Sentinel lymph node dissection (SLND) has recently been evaluated as a new staging technique for early breast cancer. To minimize the extent of surgery, the feasibility of eradicating primary breast lesions and the relative sentinel lymph nodes (SLN) under regional anesthesia was evaluated in this study. Methods and Study Design A selected population of 76 patients with suspected operable breast cancer and no clinically palpable lymph nodes was enrolled in the study. Intra- and perilesional administration of a radiotracer was performed. Lymphoscintigraphy was carried out to confirm the drainage pathway and locate the SLN. The following day, after inducing a nervous block induction of the ipsilateral intercostal nerves, we performed the surgical procedure with the help of a hand-held gamma-detecting probe. In case the primary lesion was diagnosed as invasive carcinoma by frozen section, the SLN and the remaining axillary lymph nodes (non-SLNs) were removed. The status of SLN and non-SLNs was compared. Results The primary breast lesion was located and excised in all cases (identification rate: 100%). Lymphoscintigraphy positively identified SLNs in 40/45 (89%) patients; in five patients no lymphatic drainage was detected. In 38 cases an average of 1.5 SLNs and 14 non-SLNs per patient were removed and pathologically analyzed; the remaining two patients showed SLNs in the internal mammary chain, which were not excised. Twenty-nine percent of the patients showed metastatic disease in the lymph nodes examined. Of all patients with affected nodes, 55% had cancer cells only in the SLN. No false negatives (skip metastases) were found. No immediate or long-term anesthesia-related complications (eg pleural lesions, intravascular injection) were observed. Conclusions Our data confirm the feasibility of single radiotracer administration for both occult lesion and SLN localization as well as the usefulness of SLND in staging early breast cancer. Regional anesthesia resulted in easy management and good patient compliance. This time-saving procedure allowed the completion of the whole surgical plan, reducing the recovery time without modifying the effectiveness of surgery.

Abstract
The administration of murine monoclonal antibodies (MAbs) induces, in many patients, an immunological response represented by the development of human anti-mouse antibodies (HAMA). HAMA have been previously shown to interfere in some assays for the detection of CEA, as well as other non tumor related analytes. The present study was performed to determine whether the CA 72-4 assay is affected by the presence of HAMA, and to establish conditions capable of overcoming this artifact. Serum samples obtained from 8/9 patients entered into a therapeutic protocol using 131I-labeled MAb B72.3 showed the development of apparently high levels of TAG-72 during the clinical follow-up concurrent with the appearance of elevated titers of HAMA. Heat treatment at 90°C at pH 5.0 sodium acetate, previously reported as a method of abolishing HAMA interference without affecting CEA levels, resulted in a considerable loss of detectable TAG-72. However, treatment of these samples at 90°C in pH 6.5 Bis Tris abolished the artifact due to HAMA and resulted in the reversion of reported TAG-72 levels to those observed prior to any MAb administration. As the use of murine M Abs, for both diagnostic and therapeutic applications continues to expand, the identification of this artifactual increase in reported antigen levels due to the development of HAMA has become an important factor in the use of tumor markers, e.g. TAG-72 and CEA, in the follow-up of carcinoma patients.

Abstract
Sentinel node biopsy has become a standard diagnostic procedure to assess lymph node status of various tumors. The combination of blue dye and a radioactive tracer offers the best chances of identifying the sentinel lymph node. Most progress in the technique of the sentinel node procedure has been made in melanoma and breast cancer. In melanoma, sentinel node biopsy has been introduced as a fundamental procedure for staging. Information on the lymphatic drainage from a melanoma can have a direct impact on the surgery. More recently, the technique has been successfully introduced in the management of breast cancer, in which a large number of unnecessary axillary dissections could be avoided. However, there are many other potential fields of application of the sentinel node biopsy (e.g. endometrial, vulvar, head and neck cancers) that are worthy of investigation. In any case, multicenter trials are required to standardize the procedures, taking into account several variables such as particle size and mode of delivery of the radiotracer, amount of radioactivity administered, number and location of injections, and choice of the hand-held probe. We briefly describe the technical and historical aspects of the sentinel node biopsy and summarize the main clinical trials proposed and/or performed in the field.

Abstract
The ongoing development of monoclonal antibody technology may eventually lead to the selective targeting of human carcinoma lesions by MAbs conjugated with a variety of cytotoxic agents (i.e., radionuclides, drugs, etc.). The antigen phenotype of the carcinoma cell will play an important role in the efficacy of the MAbs. Clearly, the human tumor antigens that are expressed on all carcinoma cells, and with a high antigen density, should provide the optimal target for the MAbs. More often than not, however, the human tumor antigens whose expression is highly selective for human tumor cells will also exhibit a certain degree of heterogeneity. Therefore, the ability of interferon to augment the level of expression of human tumor antigens such as TAG-72 and CEA, may play an important role in an adjuvant setting for immunoscintigraphy and/or immunotherapy. More recent observations have demonstrated that interferon treatment can also enhance the amount of TAG-72 and CEA secreted by the tumor cell. The ability of interferon to enhance the shedding of both TAG-72 and CEA could be of particular importance since recent reports suggest that their presence in the sera of patients diagnosed with gastrointestinal adenocarcinoma may be complementary and that the ability to increase either marker may facilitate earlier diagnosis of recurrent disease. It is conceivable that in subsequent years effective approaches to monitoring and/or treating malignacies may include a new combination of biological/immunological therapy.

Abstract
Increased expression of selectins has been found on endothelial cells of venules and capillaries in the tumor stroma of non-small cell lung cancer, suggesting their functional role in the process of chemotaxis for tumor cells. The present study was aimed at analyzing the role of both soluble (s)P-selectin and sE-selectin levels in association with clinico-pathological variables in 116 patients with lung cancer, 38 patients with benign diseases and 59 healthy donors. The results obtained showed that sP-selectin and sE-selectin levels were higher in patients with lung cancer compared to normal donors (p<0.02 and p<0.005, respectively). No differences were observed among patients with various benign diseases for both selectins. Increased levels of sP-selectin and sE-selectin were significantly associated with squamous lung cancer at late stages (p<0.05), but not adenocarcinoma. Both sP- and sE-selectin were independently related to the stage of squamous lung cancer by stepwise regression analysis (p<0.02 and p<0.03, respectively), while only sE-selectin was independently related to the presence of distant metastasis in the same histotype (p<0.02). These results suggest that measurement of plasma soluble selectins might represent a useful laboratory parameter in the management of patients with squamous lung cancer.

Abstract
To date no general agreement has been reached regarding the prognostic significance of CEA, CA 19-9 and CA 72-4 as serum markers in gastric cancer, and only scattered information is available on the predictive value of marker expression in tumor tissue. Therefore, a longitudinal study was designed to analyze the presurgical serum and tumor tissue content of CA 72-4, CEA and CA 19-9 in 166 patients at different stages of gastric cancer, and to evaluate the possible correlation with clinicopathological features in respect to prognostic information on relapse-free survival. The results obtained showed that 48.4% of patients with tumor recurrence had positive presurgical CA 72-4 levels compared to approximately 24% of patients who remained free of disease. Furthermore, the median presurgical serum CA 72-4 levels were significantly elevated in relapsing patients. Serosa and lymph node involvement as well as positive presurgical serum CA 72-4 levels had independent prognostic value in predicting recurrence. A significant association between disease-free survival and lymph node involvement, depth of invasion and tumor tissue content of CA 72-4 was also demonstrated. We may therefore conclude that CA 72-4 antigen can be considered the marker of choice in the follow-up of gastric cancer patients and may be used as a prognostic indicator of relapse.

Abstract
Senescence is a phenomenon characterized by a progressive decline of body homeostasis. Premature senescence acts when the cellular system is not able to adequately respond to noxious stimuli by synthesis of stressor molecules. Among those, serum-and-glucocorticoidinducible kinase-1 (SGK-1) dramatically increases under typical physiopathological conditions, such as glucocorticoid or mineralcorticoids exposure, inflammation, hyperglycemia, and ischemia. SGK-1 has been implicated in mechanism regulating oxidative stress, apoptosis, and DNA damage, which are all leading to a state of accelerating aging. Moreover, SGK-1-sensitive ion channels participate in the regulation of renal Na(+)/K(+) regulation, blood pressure, gastric acid secretion, cardiac action potential, and neuroexcitability. Recently, we demonstrated in endothelial cells as an increase in SGK-1 activity and expression reduces oxidative stress, improves cell survival and restores insulin-mediated nitric oxide production after hyperglycemia. Moreover, we showed as SGK-1 delays the onset of senescence by increasing telomerase activity, significantly decreasing reactive oxygen species (ROS) production, and by directly interacting with hTERT. Therefore, SGK-1 may represent a specific target to further develop novel therapeutic options against chronic diseases such as diabetes typical of aging. SGK-1 has been also associated with cancer, neurodegenerative diseases, and cardiovascular disease, among other age-related diseases. However, to date, the data available on SGK-1 and aging, are sparse, controversial, and only from C. elegans experimental models. In this review we sought to discuss the possible implication of SGK-1 in mechanisms regulating senescence and age-related diseases. Moreover, we aimed to discuss and identify the possible role of SGK-1 as possible molecular target to counteract and prevent aging.

Abstract
BACKGROUND Dyslipidemia is a well-known risk factor for the development of atherothrombosis; however, its involvement in venous thromboembolism (VTE) is still debated. Low levels of HDL cholesterol (HDL-C) have been found to be associated with VTE, which is a common complication of cancer and its treatment. VTE incidence is increased in cancer patients, especially those undergoing chemotherapy. OBJECTIVE We sought to investigate the value of pretreatment HDL-C in the risk prediction of future VTE in a population of ambulatory cancer patients undergoing chemotherapy. PATIENTS AND METHODS Blood lipid composition was retrospectively evaluated in 592 consecutive patients with primary (n = 373) or relapsing/recurrent (n = 219) solid cancers at the start of a new chemotherapy regimen (12% neoadjuvant, 31% adjuvant, 57% metastatic). RESULTS VTE occurred during chemotherapy in 38 patients (median time-to-event: 3 months). Mean HDL-C levels were lower in patients who developed VTE during chemotherapy (41 mg dL(-1) ; standard deviation [SD] 13 mg dL(-1) ) than in those who did not (48 mg dL(-1) ; SD 14 mg dL(-1) ). Cox proportional hazard survival analysis showed that HDL-C levels ≤ 43 mg dL(-1) were able to significantly predict a first VTE episode, with a hazard ratio of 2.87 (95% confidence interval 1.45-5.68). Moreover, patients with HDL-C levels ≤ 43 mg dL(-1) had worse 1-year VTE-free survival (86%) than those with HDL-C levels > 43 mg dL(-1) (96%; log rank test, 3.14). CONCLUSIONS Patients with low HDL-C levels have a three-fold higher risk of developing a first VTE episode during chemotherapy. Baseline analysis of HDL-C levels might be of clinical value in predicting VTE in cancer outpatients treated with anticancer drugs.

Abstract
Febrile neutropenia (FN) is a severe dose-limiting side effect of myelosuppressive chemotherapy in patients with solid tumors. Clinical practice guidelines recommend primary prophylaxis with G-CSF in patients with an overall ≥ 20 % risk of FN. AIOM Italian guidelines recommend starting G-CSF within 24-72 h after chemotherapy; for daily G-CSF, administration should continue until the absolute neutrophil count (ANC) is 1 × 10(9)/L post-nadir and should not be terminated after ANC increase in the early days of administration. The aim of this study was to assess guideline adherence in oncology practice in Italy. In this multicenter, prospective, observational study, patients were enrolled at the first G-CSF use in any cycle and were followed for two subsequent cycles (or until the end of chemotherapy if less than two additional cycles). Primary objective was to explore G-CSF use in Italian clinical practice; therefore, data were collected on the G-CSF type, timing of administration, and number of doses. 512 eligible patients were enrolled (median age, 62). The most common tumor types were breast (36 %), lung (18 %), and colorectal (13 %). A total of 1,164 G-CSF cycles (daily G-CSF, 718; pegfilgrastim, 446) were observed. Daily G-CSF was administered later than 72 h after chemotherapy in 42 % of cycles, and the median [range] number of doses was four [1, 10]. Pegfilgrastim was administered later than 72 h in 8 % of cycles. G-CSF prophylaxis in Italy is frequently administered in a manner which is not supported by evidence-based guidelines. As this practice may lead to poor outcomes, educational initiatives are recommended.

Abstract
BACKGROUND TNF-α has been proposed as a predictive factor for venous thromboembolism (VTE). Genetic polymorphisms could regulate TNF-α production. However, the relationship between TNFA gene variants and VTE is not clarified. This study aims to investigate the predictive role of five different TNFA gene promoter SNPs, or their haplotype combination(s), for a first VTE episode in gastrointestinal cancer out-patients treated with chemotherapy. PATIENTS AND METHODS Serum TNF-α levels and TNFA -863C/A, -857C/T, -376G/A, -308G/A and -238G/A gene promoter polymorphisms were retrospectively evaluated in 314 subjects, including 157 controls and 157 Caucasian patients with histologically diagnosed GI cancers beginning chemotherapy delivery (5-fluorouracil either as monotherapy or in combination with platinum compounds or irinotecan). RESULTS Haplotype analysis showed that a five-loci haplotype (CTGGG haplotype) has higher frequency in GI cancer patients who developed VTE (n = 15) during chemotherapy [odds ratio = 2.7, 95% confidence interval (CI) 1.04-7.11, P = 0.04]. GI patients who remained VTE-free did not differ in CTGGG haplotype frequency from controls. No association was observed between serum TNF-α levels and TNFA haplotype, but both were independent predictors of VTE. Approximately 20% of GI cancer patients carrying the CTGGG haplotype developed VTE compared with 4% of the remaining 101 patients (hazard ratio = 5.6, 95% CI 1.8-17.6, P = 0.003). CONCLUSION These results suggest that TNFA might represent a candidate gene contributing to VTE pathogenesis in GI cancer patients and suggest that VTE risk during chemotherapy might be genetically identified. Validation studies are needed for translation into clinical practice.

Preoperative neuroimmunotherapy with subcutaneons low-dose interleukin-2 and melatonin in patients with gastrointestinal tumors - its efficacy in preventing surgery-induced lymphocytopenia.

Abstract
Our previous studies have shown that a preoperative injection of high dose IL-2 is able to abrogate surgery-induced immunosuppression in colorectal cancer patients. Moreover, our previous clinical investigations have indicated the possibility of amplifying IL-2 activity by a concomitant administration of the pineal immunomodulating hormone melatonin (MLT). On this basis, a biological study was performed to investigate the immune effects of a preoperative biotherapy consisting of low-dose IL-2 plus MLT in patients with gastrointestinal tumors. The study included 20 consecutive patients with gastrointestinal tract tumors, who underwent radical or palliative surgery. Patients were randomized to receive no preoperative treatment or a presurgical neuroimmunotherapeutic regimen consisting of low dose of IL-2 and MLT. IL-2 was injected subcutaneously at 3 million IU twice/day for 5 days in combination with MLT at 40 mg/day in the evening. Patients underwent surgery within 36 h from the last IL-2 injection. The mean number of lymphocytes, T lymphocytes and NK cells significantly decreased during the postoperative period in control patients, whereas it increased in patients pre-treated by immunotherapy. CD25-positive mean cell number increased in both groups of patients; however, postoperative mean number of CD25 expressing cells was significantly higher in patients pretreated with IL-2 and MLT than in controls. No immunotherapy-related toxicity occurred. This preliminary study would suggest that a neuroimmunotherapeutic regimen with low-dose IL-2 and MLT given preoperatively is a well tolerated therapy, which is able to prevent surgery-induced lymphocytopenia in cancer patients. This perioperative manipulation of host anticancer defenses could have a prognostic role in the clinical course of the neoplastic disease.

Abstract
Visceral obesity is characterized by increased risk of cardiovascular disease as well as higher incidence of malignancies, including colorectal cancer (CRC), although the mechanisms linking excess adiposity with cancer are only partly characterized. Visceral obesity is currently acknowledged as a chronic inflammatory disorder and a growing body of evidence demonstrates the interconnections between obesity-related secretion pattern of adipo/cytokines and CRC. Specific molecules derived from the visceral adipose tissue (VAT), including adiponectin, leptin and resistin, are able to establish a positive feedback loop, thus increasing the proinflammatory and insulin resistant state and promoting tumorigenesis. Interestingly, these molecules have emerged as novel prognostic factors and therapeutic targets. This review will focus on current molecular and clinical evidence linking VAT-related inflammation to CRC initiation and progression, and summarize the role of dietary factors and lifestyle interventions aimed at promoting weight control and physical activity on CRC prevention and prognosis.

Abstract
OBJECTIVES Evaluation of the impact of a biscuit containing the probiotics Bifidobacterium longum Bar33 and Lactobacillus helveticus Bar13 on the intestinal microbiota in the elderly. DESIGN Randomized double-blind placebo-controlled trial. PARTICIPANTS Thirty-two elderly volunteers living in Italy. The group was composed of 19 women and 13 men aged between 71 and 88 years (mean 76). INTERVENTION Subjects were randomized in two groups consuming one dose of the probiotics-containing biscuit or placebo once a day for 30 days. MEASUREMENTS For each subject the intestinal microbiota was characterized using the phylogenetic microarray platform HTF-Microbi.Array before and after intervention. RESULTS Our data demonstrated that one-month consumption of a probiotics-containing biscuit was effective in redressing some of the age-related dysbioses of the intestinal microbiota. In particular, the probiotic treatment reverted the age-related increase of the opportunistic pathogens Clostridium cluster XI, Clostridium difficile, Clostridium perfringens, Enterococcus faecium and the enteropathogenic genus Campylobacter. CONCLUSION The present study opens the way to the development of elderly-tailored probiotic-based functional foods to counteract the age-related dysbioses of the intestinal microbiota.

Abstract
A fairly large body of evidence has shown that insulin is a tumour-promoting agent, especially for breast cancer. High circulating and microenvironmental levels of insulin may directly increase the risk of breast cancer via the activation of cognate receptors expressed on normal and cancer cells and indirectly be associated with other known metabolic risk factors of cancer that usually are present in conjunction with the hyperinsulinic state. The focus of this review is to analyse and discuss available data in the literature on the possible causative/prognostic role of insulin resistance/hyperinsulinemia in breast cancer development and progression.

Abstract
BACKGROUND Homocysteinemia has been associated with oncogenic risk. This study was designed to investigate the homocysteine (Hcy) genotype/phenotype interactions together with the inflammatory and nutritional status of cancer patients. PATIENTS AND METHODS The Hcy levels were analyzed in 47 cancer patients in association with methylenetetrahydrofolate reductase (MTHFR) polymorphisms, folate and inflammatory markers. RESULTS The MTHFR C677T and A1298C genotype distributions did not differ from those predicted by the Hardy-Weinberg distribution. Conversely, the Hcy levels were higher in the cancer patients (p=0.04), who were also characterized by low-grade inflammation. The Hcy levels correlated with the interleukin-6 (IL-6) (p=0.001), tumor necrosis factor-alpha (TNF-alpha) (p=0.042) and folate (p<0.0001) levels of the patients. Multivariate analysis showed that TNF-alpha (p=0.014) and folate (p=0.019) were independent predictors of elevated Hcy levels in the cancer patients. CONCLUSION The MTHFR polymorphisms do not significantly contribute to tHcy (total Hcy) levels in cancer patients, and cancer-related inflammation may be associated with elevated tHcy levels, possibly involving a TNF-alpha mediated pathway.
