Adjuvant chemotherapy may contribute to an increased risk for metabolic syndrome in patients with breast cancer.

PURPOSE: Cytotoxic treatment may cause weight gain and important alterations in the metabolic status of breast cancer (BC) patients. The aim of this study was to investigate the changes in metabolic and anthropometric parameters of patients with BC who received adjuvant chemotherapy. METHODS: All consecutive women treated with adjuvant TAC (docetaxel 75 mg/m(2), doxorubicine 50 mg/m(2), cyclophosphamide 500 mg/m(2)) chemotherapy for node-positive breast carcinoma at our Institution between 2008 and 2010 were included. RESULTS: Among 104 patients, 84 of them were stage II and 20 of them were stage III. When we compared the measurements between 1(st) and 6(th) adjuvant chemotherapy, we observed statistically significant increases in weight and serum triglyceride levels, and decreases in high density lipoprotein, apolipoprotein A-1, transferrin, albumin and prealbumin levels. An elevation of follicle stimulating hormone, luteinizing hormone together with the decrease of estradiol was detected. Waist-to-hip ratio has also increased significantly. In subgroup analyses, we observed dramatic changes in body mass index in pre-menopausal women whereas no significant change was seen in the post-menopausal group. CONCLUSIONS: Adjuvant chemotherapy may contribute to an increased risk for metabolic syndrome in patients with BC and these changes are more profound in pre-menopausal patients.

A multicenter, retrospective archive study of radiological and clinical features of ALK-positive non-small cell lung cancer patients and crizotinib efficacy.

To evaluate radiological and clinical features in metastatic anaplastic lymphoma kinase+ non-small cell lung cancer patients and crizotinib efficacy in different lines. This national, non-interventional, multicenter, retrospective archive screening study evaluated demographic, clinical, and radiological imaging features, and treatment approaches in patients treated between 2013-2017. Totally 367 patients (54.8% males, median age at diagnosis 54 years) were included. Of them, 45.4% were smokers, and 8.7% had a family history of lung cancer. On radiological findings, 55.9% of the tumors were located peripherally, 7.7% of the patients had cavitary lesions, and 42.9% presented with pleural effusion. Pleural effusion was higher in nonsmokers than in smokers (37.3% vs. 25.3%, P = .018). About 47.4% of cases developed distant metastases during treatment, most frequently to the brain (26.2%). Chemotherapy was the first line treatment in 55.0%. Objective response rate was 61.9% (complete response: 7.6%; partial response: 54.2%). The highest complete and partial response rates were observed in patients who received crizotinib as the 2nd line treatment. The median progression-free survival was 14 months (standard error: 1.4, 95% confidence interval: 11.2-16.8 months). Crizotinib treatment lines yielded similar progression-free survival (P = .078). The most frequent treatment-related adverse event was fatigue (14.7%). Adrenal gland metastasis was significantly higher in males and smokers, and pleural involvement and effusion were significantly higher in nonsmokers-a novel finding that has not been reported previously. The radiological and histological characteristics were consistent with the literature data, but several differences in clinical characteristics might be related to population characteristics.

Macular edema in unregulated type 2 diabetic patients following glycemic control.

BACKGROUND: We undertook this study to evaluate the changes in macular edema of uncontrolled type 2 diabetes mellitus patients with the regulation of hyperglycemia. METHODS: The study population was comprised of 35 type 2 diabetes mellitus patients who had poorly regulated blood glucose values. Ophthalmic examinations including baseline and 6-month macular edema index values of patients by Heidelberg Retinal Tomography (HRT) macular module were done. RESULTS: Twenty four (68.6%) female patients and 11 (31.4%) male patients with a mean age of 50.7 +/- 10.3 (mean +/- SD) years and mean diabetic duration of 9.8 +/- 7.5 years participated in the study. Twenty two (62.9%) did not have diabetic retinopathy (DR), whereas 13 (37.2%) had background DR with macular edema. There was a significant correlation between duration of diabetes and HRT-II macula edema index for the right and left eyes (r = 0.40, p = 0.21 and r = 0.40, p = 0.22, respectively). CONCLUSIONS: Macular edema did not change significantly by regulation of glycemic control in the study group.

Combined gossypol and zoledronic acid treatment results in synergistic induction of cell death and regulates angiogenic molecules in ovarian cancer cells.

In the present study, we aimed to evaluate the possible synergistic, cytotoxic effects of combination treatment of gossypol and zoledronic acid, in human ovarian cancer cell lines, OVCAR-3 and MDAH-2774, and to elucidate the role of this novel combination treatment on angiogenesis-related molecules in ovarian cancer. The XTT cell viability assay was used for showing cytotoxicity. Both DNA fragmentation by ELISA assay and caspase 3/7 activity measurement were used for demonstrating apoptosis. To elucidate the angiogenic molecules affected by combination treatment, mRNA levels of angiogenic molecules were measured using the Human Angiogenesis RT2 ProfilerTM PCR Array (SuperArray, Frederick, MD) in ovarian cancer cell lines, OVCAR-3 and MDAH-2774.The combined treatment resulted in significant, synergistic cytotoxicity, and induced apoptosis. This effect was observed to happen in a dose- and time-dependent manner. Moreover, the combination treatment of 10 microM gossypol and 5 microM zoledronic acid resulted in significant down-regulation (>or= thee-fold) in mRNA levels of some pivotal angiogenic molecules in OVCAR-3 and MDAH-2774 cells as compared to the untreated control. However, this effect was different in the two ovarian cancer cell lines observed. Gossypol, in combination with zoledronic acid, may provide a rational treatment option for ovarian cancer, not only by direct inhibition of cell proliferation, but also inhibition of angiogenesis-related molecules.

Lower respiratory tract complications during nasal provocation: nonspecific stimulant or specific allergen?

BACKGROUND: Allergic rhinitis (AR) is an allergic inflammatory disease in which allergen exposure leads to the appearance of symptoms in sensitized individuals because of histamine liberation from nasal mucosal mast cells. Comorbidity of this disease with allergic asthma is common. Therefore, the one airway one disease theory has been put forward. Lower respiratory tract provocation tests with both nonspecific (methacholine) and specific stimulants (allergen) have yielded positive results in nonasthmatic patients with AR. However, not enough research is available to demonstrate whether there is a response in the lower respiratory tract during nasal provocation tests (NPTs) performed to evaluate only nasal airway in these patients. OBJECTIVES: To determine if the lower respiratory tract was affected as a result of NPTs with nonspecific and specific stimulants in nonasthmatic patients with AR and to determine the frequency of lower respiratory tract obstruction due to NPT with nonspecific and specific stimulants. METHODS: Thirty-six participants were enrolled in the study between November 2005 and January 2006 (18 AR patients and 18 healthy control subjects). Patients underwent 2 sessions of NPT. The first session was performed with nasal methacholine as a nonspecific stimulant, and the second session was performed with nasal Olea europaea extract as a specific stimulant. The control group underwent only nonspecific nasal provocation with methacholine. Basal nasal opening and nasal pressures were evaluated spirometrically by rhinomanometric measurements and basal respiratory function tests in both groups before methacholine nasal provocation. Whether or not nasal provocation was achieved, spirometric measurements were performed in all patients and controls after NPTs. RESULTS: NPTs with methacholine resulted in a similar frequency of nasal provocation in the patient and control groups (P = .63). However, the mean methacholine dose was lower in patients with AR (P = .049). There was a decrease in parameters of asthma, including the ratio of forced expiratory volume in 1 second to forced vital capacity (P = .04), peak expiratory flow (P = .01), and forced expiratory flow between 25% and 75% (P = .004), as a result of NPTs with methacholine in the patient group. However, NPTs with allergen did not cause a change in lower respiratory tract obstruction criteria. CONCLUSIONS: Lower respiratory tract obstruction can occur after NPTs with nonspecific stimulants; therefore, tests performed with specific allergens can be regarded as safer.
