RESUMEN

BACKGROUND: Inflammatory myofibroblastic tumors (IMTs) are rare sarcomas that can occur at any age. Surgical resection is the primary treatment for patients with localized disease; however, these tumors frequently recur. Less commonly, patients with IMTs develop or present with metastatic disease. There is no standard of care for these patients and traditional cytotoxic therapy is largely ineffective. Most IMTs are associated with oncogenic ALK, ROS1 or PDGFRß fusions and may benefit from targeted therapy. PATIENT AND METHODS: We sought to understand the genomic abnormalities of a patient who presented for management of metastatic IMT after progression of disease on crizotinib and a significant and durable partial response to the more potent ALK inhibitor ceritinib. RESULTS: The residual IMT was resected based on the recommendations of a multidisciplinary tumor sarcoma tumor board and analyzed by whole-genome mate pair sequencing. Analysis of the residual, resected tumor identified a chromoplectic TPM3-ALK rearrangement that involved many other known oncogenes and was confirmed by rtPCR. CONCLUSIONS: In our analysis of the treatment-resistant, residual IMT, we identified a complex pattern of genetic rearrangements consistent with chromoplexy. Although it is difficult to know for certain if these chromoplectic rearrangements preceded treatment, their presence suggests that chromoplexy has a role in the oncogenesis of IMTs. Furthermore, this patient's remarkable response suggests that ceritinib should be considered as an option after progression on crizotinib for patients with metastatic or unresectable IMT and ALK mutations.

RESUMEN

Wingless-type protein (Wnt)/ß-catenin pathway alterations in non-small cell lung cancer (NSCLC) are associated with poor prognosis and resistance. In 598 stage III-IV NSCLC patients receiving platinum-based chemotherapy at the MD Anderson Cancer Center (MDACC), we correlated survival with 441 host single-nucleotide polymorphisms (SNPs) in 50 Wnt pathway genes. We then assessed the most significant SNPs in 240 Mayo Clinic patients receiving platinum-based chemotherapy for advanced NSCLC, 127 MDACC patients receiving platinum-based adjuvant chemotherapy and 340 early stage MDACC patients undergoing surgery alone (cohorts 2-4). In multivariate analysis, survival correlates with SNPs for AXIN2 (rs11868547 and rs4541111, of which rs11868547 was assessed in cohorts 2-4), Wnt-5B (rs12819505), CXXC4 (rs4413407) and WIF-1 (rs10878232). Median survival was 19.7, 15.6 and 10.7 months for patients with 1, 2 and 3-5 unfavorable genotypes, respectively (P=3.8 × 10(-9)). Survival tree analysis classified patients into two groups (median survival time 11.3 vs 17.3 months, P=4.7 × 10(-8)). None of the SNPs achieved significance in cohorts 2-4; however, there was a trend in the same direction as cohort 1 for 3 of the SNPs. Using online databases, we found rs10878232 displayed expression quantitative trait loci correlation with the expression of LEMD3, a neighboring gene previously associated with NSCLC survival. In conclusion, results from cohort 1 provide further evidence for an important role for Wnt in NSCLC. Investigation of Wnt inhibitors in advanced NSCLC would be reasonable. Lack of an SNP association with outcome in cohorts 2-4 could be due to low statistical power, impact of patient heterogeneity or false-positive observations in cohort 1.

RESUMEN

The UN Sustainable Development Goals (SDGs) strive to eliminate poverty, preserve the planet, and promote shared prosperity through sustainable and inclusive means by 2030. This requires the implementation of a diverse set of strategies to overcome challenges and foster synergies among different SDG targets, facilitating the achievement of these ambitious goals. The aim of this review is to highlight the world's progress toward SDGs with the utilization of biotechnological advancements, including targets, strategies, synergies, and challenges. We scrutinized published research articles in peer-reviewed journals, UN reports, and scientific books that were relevant to the current topic. We identified some major challenges faced by the countries, especially developing ones, in the way of sustainable progress. These include inadequate governance, fragile states, armed conflicts, rising inequality, limited economic progress, climate change, environmental degradation, and food insecurity. Biotechnological advancements contribute to sustainable resource management, environmental conservation, and ecosystem restoration. Collaboration among countries and organizations is crucial for sharing knowledge and providing technical and financial assistance to developing nations.

RESUMEN

The prosperity of our planet relies on the cardinal concept of sustainable development. The dietary choices of humans play a pivotal role in creating a peaceful and contented world. In this context, the Mediterranean diet (MD) has emerged as a valuable approach to accomplishing such progress, wherein the rights of all living beings are equally honored. This review aims to analyze the significance of a plant-based diet, particularly the Mediterranean diet, in attaining sustainable development goals. A comprehensive search of the literature was conducted to gather the most reliable and published scientific evidence from books and papers. Within this research endeavor, specific Sustainable Development Goals (SDGs) are individually addressed in relation to the adoption of the Mediterranean diet as a foundational nutritional paradigm. Our research findings underscore the immense importance of the MD and advocate for its worldwide implementation to accomplish sustainable development objectives. The MD emerges as the most suitable dietary option for fostering sustainability and tranquility in our world. It is crucial to prioritize the global implementation of the MD to genuinely achieve sustainable development.

RESUMEN

BACKGROUND: Small-cell lung cancer (SCLC) carries the worst prognosis among lung cancer diagnoses. Combined radiation and chemotherapy is the standard of care; however, treatment outcomes vary. Variability in the rate at which chemotherapy agents are metabolized and in the capacity of repairing DNA damage has been hypothesized to be partly responsible for the treatment response variation. Genes in the glutathione metabolism and DNA repair pathways were tested through tag single-nucleotide polymorphisms (SNPs) to assess their association with survival in SCLC. PATIENTS AND METHODS: Blood DNA from 248 patients with primary SCLC was genotyped for 419 tag SNPs from 49 genes in the glutathione and DNA repair pathways. Association analyses with patient survival were carried out at single-SNP, whole-gene, and haplotype levels after adjusting for age, gender, tumor stage, treatment modalities, and smoking history. RESULTS: Among the 375 SNPs successfully genotyped, 21 SNPs, located on 11 genes, showed significant association with survival. Whole-gene analyses confirmed 3 of the 11 genes: GSS, ABCC2, and XRCC1. Haplotype analyses of these three genes identified haplotype combinations and genomic locations underlying the observed SNP associations. CONCLUSION: Genetic variations in genes involved in the glutathione and DNA repair pathways are associated with SCLC survival.

RESUMEN

This paper describes the development and evaluation of an optical fiber immunosensor (OFIS) for the detection of IgG antibody to Rift Valley fever virus (RVFV) in humans. The OFIS was based on a sandwich enzyme-linked immunosorbent assay (S-ELISA) format, whereby gamma-irradiated RVFV and control antigens were immobilized on the optical fiber surface coated with a mouse anti-RVFV antibody. Data sets derived from field-collected sera in Africa (n=242) were dichotomized according to the results of a virus neutralization test. Compared to standard colorimetric S-ELISA, the OFIS technique was more sensitive in detecting smaller quantity of specific IgG to RVFV in human sera. At cut-off value selected at a 95% accuracy level by the two-graph receiver operating characteristic analysis, the OFIS diagnostic sensitivity was 97.22% and diagnostic specificity 98.86%. Our results demonstrate that the OFIS technology reported here is highly accurate, simple to perform and has the potential to be used in a portable format.

RESUMEN

We describe herein a newly developed optical immunosensor for detection of antibodies directed against antigens of the Ebola virus strains Zaire and Sudan. We employed a photo immobilization methodology based on a photoactivatable electrogenerated poly(pyrrole-benzophenone) film deposited upon an indium tin oxide (ITO) modified conductive surface fiber-optic. It was then linked to a biological receptor, Ebola virus antigen in this case, on the fiber tip through a light driven reaction. The photochemically modified optical fibers were tested as an immunosensor for detection of antibodies against Ebola virus, in animal and human sera, by use of a coupled chemiluminescent reaction. The immunosensor was tested for sensitivity, specificity, and compared to standard chemiluminescent ELISA under the same conditions. The analyte, anti-Ebola IgG, was detected at a low titer of 1:960,000 and 1:1,000,000 for subtypes Zaire and Sudan, respectively. While the same serum tested by ELISA was one order (24 times) less sensitive.

RESUMEN

In the construction of luminescent yeast cell based fibre-optic biosensors, we demonstrate a novel approach for estrogenic endocrine disrupting chemical (EDC) biodetection by entrapping genetically modified Saccharomyces cerevisiae cells, containing the estrogen receptor alpha-mediated expression of the luc reporter gene, in hydrogel matrices based on calcium alginate or PVA. In order to insure a significant signal, an optimal immobilization ratio of 1:2 alginate 3% (w/v): 5 x 10(6) [cells/ml], respectively, was used with the highest 17-beta-estradiol (beta-E2) induction factor after 2.5 h of incubation with 10[nM] beta-E2. It was shown that biocompatible alginate beads, 4.27-4.55 x 10(5) [CFU/bead], which were characterized by a detection limit of 0.08[microg l(-1)] and an EC50 of 0.64[microg l(-1)] for beta-E2, retained their viability for luminescence measurements after 1 month of storage at -80 degrees C slow freeze condition, and thus repeated cell cultivations were not required. The assay reproducibility for each tested EDC, represented by the coefficients of variation (CV), ranged from 4.35 to 18.47%. An alternative immobilization method, based on a room temperature partial drying of polyvinyl alcohol (PVA) solution (LentiKat Liquid) and cell suspension mix, was investigated with only a slightly lower detection limit for beta-E2 than that reported with alginate beads. Alginate yeast based hydrogels may also be applicable to the analysis of environmental water samples since the trend of detected estrogenic activities with alginate beads roughly correlated with LC-MS-MS analytical results.

RESUMEN

Farnesyl protein transferase (FT), an enzyme that catalyzes the first step in the posttranslational modification of ras and a number of other polypeptides, has emerged as an important target for the development of anticancer agents. SCH66336 is one of the first FT inhibitors to undergo clinical testing. We report a Phase I trial to assess the maximum tolerated dose, toxicities, and biological effectiveness of SCH66336 in inhibiting FT in vivo. Twenty patients with solid tumors received 92 courses of escalating SCH66336 doses given orally twice a day (b.i.d.) for 7 days out of every 3 weeks. Gastrointestinal toxicity (nausea, vomiting, and diarrhea) and fatigue were dose-limiting at 400 mg of SCH66336 b.i.d. Moderate reversible renal insufficiency, secondary to dehydration from gastrointestinal toxicity, was also seen. Inhibition of prelamin A farnesylation in buccal mucosa cells of patients treated with SCH66336 was demonstrated, confirming that SCH66336 inhibits protein farnesylation in vivo. One partial response was observed in a patient with previously treated metastatic non-small cell lung cancer, who remained on study for 14 months. This study not only establishes the dose for future testing on this schedule (350 mg b.i.d.) but also provides the first evidence of successful inhibition of FT in the clinical setting and the first hint of clinical activity for this class of agents.

RESUMEN

PURPOSE: Because small-cell lung cancer is a rapidly proliferating tumor, it was hypothesized that it may be more responsive to thoracic irradiation (TI) given twice-daily than once-daily. This hypothesis was tested in a phase III trial. PATIENTS AND METHODS: Patients with limited-stage small-cell lung cancer were entered onto a phase III trial, and all patients initially received three cycles of etoposide (130 mg/m(2) x 3) and cisplatin (30 mg/m(2) x 3). Subsequently, patients who did not have progression to a distant site (other than brain) were randomized to twice-daily thoracic irradiation (TDTI) versus once-daily thoracic irradiation (ODTI) given concomitantly with two additional cycles of etoposide (100 mg/m(2) x 3) and cisplatin (30 mg/m(2) x 3). The irradiation doses were TDTI, 48 Gy in 32 fractions, with a 2.5-week break after the initial 24 Gy, and ODTI, 50.4 Gy in 28 fractions. After thoracic irradiation, the patients received a sixth cycle of etoposide/cisplatin, followed by prophylactic cranial irradiation (30 Gy/15 fractions) if they had a complete response. RESULTS: Of 311 assessable patients enrolled in the trial, 262 underwent randomization to TDTI or ODTI. There were no differences between the two treatments with respect to local-only progression rates, overall progression rates, or overall survival. The patients who received TDTI had greater esophagitis (> or = grade 3) than those who received ODTI (12.3% v 5.3%; P =.05). Although patients received thoracic irradiation encompassing the postchemotherapy volumes, only seven of 90 local failures were out of the portal of irradiation. CONCLUSION: When TI is delayed until the fourth cycle of chemotherapy, TDTI does not result in improvement in local control or survival compared with ODTI.

RESUMEN

Suramin represents a new class of antitumor drugs that targets growth factor networks. In this Phase II trial, suramin was administered by continuous infusion to 10 patients with advanced breast cancer. The target level of 280 microgram/ml suramin was achieved in a median of 10 days; toxicities in this patient group were low. We monitored the insulin-like growth factor (IGF) network in these patients because of the previously defined growth-promoting role of the IGFs in breast cancer. Plasma levels of total IGF-I and total IGF-II showed variable responses to suramin with median decreases of 24 and 23%, respectively, for the 10 patients; for total IGF-I levels, this did not reach statistical significance. On the other hand, free IGF-I plasma levels were consistently and dramatically increased (over 250%) after suramin infusion. IGF-binding proteins (IGFBPs), modulators of IGF bioavailability, were also measured. Levels of IGFBP-3, the major carrier of IGFs in the circulation, were decreased 21% after suramin treatment when measured by immunoradiometric assay. However, the majority of the plasma IGFBP-3 remaining after suramin was not the intact high-affinity IGF-binding form but rather a 30-kDa fragment with markedly reduced affinity for IGF-I. IGFBP-3 protease activity was evident in the plasma of 3 of 10 patients after suramin. Measurements of plasma IGFBP-1, IGFBP-2, and IGFBP-4 revealed no significant changes in response to suramin. The dramatic increase in active free IGF-I seen after suramin raises concern and underscores the importance of measuring relevant biomarkers in clinical trials.

RESUMEN

The level of serum neuron-specific enolase (NSE) has been implicated as a prognostic factor for patients with small cell lung cancer (SCLC). A prospective evaluation was undertaken to assess the prognostic significance of pretreatment NSE and treatment-induced minimum NSE values in patients with SCLC. Patients from two Phase III North Central Cancer Treatment Group trials [one for patients with extensive stage SCLC and one for patients with limited stage SCLC] were asked to enter this laboratory correlational trial. Both trials included treatment with four to six cycles of etoposide and cisplatin, and 121 patients (71 extensive stage SCLC and 50 limited stage SCLC) were entered into the present study of NSE. Pretreatment NSE values and treatment-induced minimum NSE values were independent predictors of time to progression and survival in multivariate analysis. Hazard rate modeling allowed the formulation of specific relationships of NSE to time to progression and survival. Pretreatment NSE levels inversely correlated with time to progression and survival in these patients with SCLC. Pretreatment NSE accounted for 28% of the variance in survival. Both pretreatment NSE and treatment-induced minimum NSE were independent prognostic predictors of time to progression and survival.

RESUMEN

Lung cancer (LC) and chronic obstructive pulmonary lung diseases (COPDs; including emphysema and chronic bronchitis) share a common etiology. Despite the known associations of alpha1-antitrypsin deficiency (alpha1AD) with COPD and COPD with LC, few studies examined the association of alpha1AD alleles and LC. We hypothesize that heterozygous individuals who carry a deficient allele of the alpha1AD gene Pi (protease inhibitor locus) are at an increased risk of developing LC. The Pi locus is highly polymorphic with >70 variants reported. There are at least 10 alleles associated with deficiency in alpha1-antitrypsin. Using an exact binomial test, we compared the alpha1AD carrier rate in 260 newly diagnosed Mayo Clinic LC patients to the reported carrier rate in Caucasians in the United States (7%). alpha1AD carrier status, determined by isoelectric focusing assay, was examined with respect to the history of cigarette smoking, COPD, and histological types. Thirty-two of the 260 patients (12.3%; 95% confidence interval, 8.6-16.9%) carried an alpha1AD allele, which was significantly higher than expected (P = 0.002). Twenty-four of the 32 carriers had allele S, 6 had allele Z, and 2 had allele I. Patients who never smoked cigarettes were three times more likely to carry a deficient allele (20.6%; P = 0.008), although smokers had a higher carrier rate (11.1%; P = 0.025) when compared with the 7% rate. Patients with squamous cell or bronchoalveolar carcinoma had a significantly higher carrier rate than expected (15.9% and 23.8%, P < or = 0.01, respectively). Our preliminary findings suggest that individuals who carry an alpha1AD allele may have an increased risk for developing LC, specifically squamous cell or bronchoalveolar carcinoma.

RESUMEN

In 1994, approximately 34,000 to 43,000 Americans will be diagnosed with small cell lung cancer, and 60% to 70% of these individuals will have extensive-stage disease. The median survival time of patients with extensive-stage small cell lung cancer is 8 to 10 months and 10% or less will survive 2 years. There have been no major advances in the treatment of this stage of disease in the past decade. Phase II trials with promising new single-agent chemotherapeutic drugs are justifiable. We report the design and toxicity of a phase II trial with single-agent paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in previously untreated patients with extensive-stage small cell lung cancer.

RESUMEN

PURPOSE: We conducted a Phase I study of bischloroethylnitrosourea (BCNU), cisplatin, and oral etoposide administered prior to and during accelerated hyperfractionated radiation therapy in newly diagnosed high-grade glioma. Pharmacokinetic studies of oral etoposide were also done. METHODS AND MATERIALS: Patients started chemotherapy after surgery but prior to definitive radiation therapy (160 cGy twice daily x 15 days; 4800 cGy total). Initial chemotherapy consisted of BCNU 40 mg/m2 days 1-3, cisplatin 30 mg/m2 days 1-3 and 29-31, and etoposide 50 mg orally days 1-14 and 29-42, repeated in 8 weeks concurrent with radiation therapy. BCNU 200 mg/m2 every 8 weeks x 4 cycles was given after radiation therapy. RESULTS: Sixteen patients, 5 with grade 3 anaplastic astrocytoma and 11 with glioblastoma were studied. Grade 3-4 leukopenia (38%) and thrombocytopenia (31%) were dose-limiting. Other toxicities were anorexia (81%), nausea (94%), emesis (56%), alopecia (88%), and ototoxicity (38%). The maximum tolerated dose was BCNU 40 mg/m2 days 1-3, cisplatin 20 mg/m2 days 1-3 and 29-31, and oral etoposide 50 mg days 1-21 and 29-49 prior to radiation therapy and repeated in 8 weeks with the start of radiation therapy followed by BCNU 200 mg/m2 every 8 weeks for 4 cycles. Median time to progression and survival were 13 and 14 months respectively. Responses occurred in 2 of 9 (22%) patients with evaluable disease. In pharmacokinetic studies, all patients achieved plasma concentrations of >0.1 microg/ml etoposide (the in vitro radiosensitizing threshold), following a 50 mg oral dose. The mean +/- SD 2 hr and 6 hr plasma concentrations were 0.92 +/- 0.43 microg/ml and 0.36 +/- 0.12 microg/ml, respectively. Estimated duration of exposure to >0.1 microg/ml etoposide was 10-17 hr. CONCLUSIONS: Preirradiation chemotherapy with BCNU, cisplatin, and oral etoposide with accelerated hyperfractionated radiation therapy in high-grade gliomas is feasible and merits further investigation. Sustained radiosensitizing concentrations can be achieved with low oral doses of etoposide.

RESUMEN

Small cell lung cancer (SCLC) accounts for 20% to 25% of cases of bronchogenic carcinoma and results in pronounced morbidity and mortality in the United States. More than 90% of cases of SCLC are caused by cigarette smoking. Common pulmonary manifestations are dyspnea, persistent cough, hemoptysis, and postobstructive pneumonia. At the time of diagnosis, patients usually have extensive disease. To date, therapeutic approaches have made only modest advances in outcome. Combined modality approaches, such as radiotherapy administered concomitantly with the initiation of chemotherapy, induction chemotherapy followed by radiotherapy administered during the subsequent courses of chemotherapy, sequential chemotherapy and radiotherapy, and courses of radiotherapy split between cycles of chemotherapy, are important for improving survival in patients with SCLC.

RESUMEN

BACKGROUND: Investigations on environmental tobacco smoke (ETS) exposure that include source intensity, childhood exposure, and association with histologic subtypes among never smoking lung cancer cases are limited. We report the patterns of ETS exposure history in a clinical cohort of women with newly diagnosed lung cancer. METHODS: From 1997 to 2001, 810 women with lung cancer were interviewed to obtain data including the source, intensity, and duration of ETS exposure. In this descriptive study, relationships between smoking history, ETS exposure, and lung cancer histologic subtypes were analyzed. RESULTS: Among the 810 patients, 773 (95.4%) reported personal smoking or ETS exposure including 170 of 207 (82%) never smokers. Among the never smokers with a history of ETS exposure, the mean years of exposure were 27 from a smoking spouse, 19 from parents, and 15 from co-workers. For each major subtype of lung cancer (adenocarcinoma, squamous cell, unclassified non-small cell lung cancer, small cell, or carcinoids) among never smokers, 75-100% of patients had ETS exposure. Trends for adenocarcinoma, squamous, and small cell carcinoma are statistically significant using the Cochran-Armitage Test for Trend (P<0.001) among never smokers without ETS exposure, never smokers with ETS exposure, former smokers, and current smokers. CONCLUSIONS: Over 95% of women with lung cancer in our study were exposed to tobacco smoke through a personal smoking history or ETS. The cumulative amount of tobacco smoke exposure may be significantly underestimated if only personal smoking history is considered. Our results add to the public health implications of exposure to tobacco smoke and highlight the importance of eliminating tobacco smoking in public and private settings.

RESUMEN

This study evaluates the influence of gender on survival and tumor recurrence following adjuvant therapy of completely resected stages II and IIIa non-small cell lung cancer (NSCLC). The Eastern Cooperative Oncology Group conducted a randomized prospective trial of adjuvant therapy in patients with completely resected stages II and IIIa NSCLC. A laboratory correlative study assessed the prevalence and prognostic significance of p53 and K-ras mutations. Patients were randomized to receive either radiotherapy (RT) alone or four cycles of cisplatin and VP-16 administered concurrently with radiotherapy (CRT). Median survival was 35 months for the 285 men and 41 months for the 203 women enrolled in the study (P = 0.12). The relative risk (RR) of death for men vs women was 1.19 (95% confidence interval [CI], 0.95-1.49). Median survival of the 147 men and 95 women randomized to the RT arm was 39 months each (P = 0.35). Median survival of the 138 men and 108 women randomized to the CRT arm was 30 and 42 months, respectively (P = 0.18). Disease recurrence patterns were similar between the genders. Univariate and multivariate analyses demonstrated improved survival for women with tumors of non-squamous histology (P < 0.01). The distribution of p53 and K-ras mutations was similar between the genders and had no influence on survival. Gender does not influence survival following adjuvant RT or CRT administered to patients with completely resected stages II and IIIa NSCLC. However, women with non-squamous histology have increased survival when compared to men.

RESUMEN

Adoptive immunotherapy (AI) with interleukin-2 (IL-2) and lymphokine-activated killer cells (LAK) is an antineoplastic modality in which immune-activated cells are administered to a host with advanced cancer in an attempt to mediate tumor regression. Levamisole (LEV), an immune stimulant, has been suggested to have therapeutic effectiveness in a variety of cancers. After a phase I trial of recombinant IL-2 plus LEV, a phase II trial of this combination was conducted in patients with advanced malignant melanoma. Nineteen patients were entered in the trial. They received IL-2 at 3 x 10(6) U/m2 subcutaneously daily x 5 plus LEV 50 mg/ m2 orally three times daily (p.o. t.i.d.) x 5. Patients were reevaluated at four-week intervals. None of the patients achieved a partial or complete regression (PR, CR). The median time to treatment failure (refusal, progression, or off study due to toxicity) was 56 days. Grade IV toxicities included vomiting (3 patients), lethargy (1 patient), and musculoskellar pain (1 patient). This regimen is not recommended for further testing in patients with advanced malignant melanoma.
