RESUMEN

INTRODUCTION: Breast-cancer is a common-cause of death in women.(1) We investigated the effects of before/after-NACT on hemoglobin-albumin-lymphocyte-platelet (HALP) scores and of changes therein on clinical/pathological-responses. MATERIALS AND METHODS: One-hundred-twenty-seven breast-cancer-patients receiving-NACT between December 2009 - January 2019 were investigated retrospectively. RESULTS: The mean - age was 50.3±12.3 (min 27 - max 79), and 125 patients (98.4 %) were women. Fifty-four (42.5 %) were premenopausal and 71 (55.9 %) postmenopausal. Invasive-ductal-carcinoma was present in 111 patients (92.5 %). Eighty patients (70.2 %) were ≤ T2 and 34 (29.8 %) > T2. Lymph-node-status was positive in 99 patients (83.2 %) and negative in 20 (16.8 %). Ki-67 was ≤ 10 % in 22 (28.9 %), 11-20 % in 23 (30.3 %), and > 20 % in 31 (40.8 %). Complete clinical response was observed in 27 (21.3 %), partial-response in 76 (59.8 %), stable-disease in 21 (16.5 %), and progressive-disease in 3 patients (2.4 %). The objective-response-rate (ORR) was 103 (81.1 %). Pathological-complete-response (pCR) was observed in 24 patients (18.9 %). ORR was higher in Ki-67 > 20 % compared to ≤ 10 % and 10-20 % (90.3 % vs 59.0 % / 78.3 %, respectively, p: 0.027), but no difference occurred in pCR. Neutrophil-lymphocyte-ratio (NLR), platelet-lymphocyte-ratio (PLR), prognostic-nutritional-index (PNI), and HALP were measured before/after NACT. Associations with ORR and pCR were investigated via changes in these with NACT (excepting-PNI), but no-significant results emerged. CONCLUSIONS: Higher ORR occurred post-NACT in patients with Ki-67 >20 %, while NLR, PLR, PNI, and HALP before/after-NACT and post-NACT-changes (excepting-PNI) had no-effect on ORR/pCR (Tab. 5, Ref. 21).

RESUMEN

CONTEXT: Cetuximab is an epidermal growth factor receptor inhibitor. It is frequently used in the treatment of solid tumors. However, it has a high potential to cause acne-like rash. Demodex mites, which are known to increase in number in immunosuppressive circumstances, are closely related to the acneiform lesions. OBJECTIVE: The aim of this study is to evaluate the presence of demodex mites in acne-like rash that appears under the treatment of Cetuximab. METHODS: We reviewed the medical records of patients who applied to our clinic with cetuximab induced papulopustular rashes between November 2014 and March 2016. Demodex sampling was performed by standardized skin surface biopsy (SSSB) in a total of 11 patients (eight males and three females). Infestation was defined as at least 5 living parasites/cm2 of skin. RESULTS: Upon the SSSB examination in 10 out of the 11 patients, no demodex mites were detected. Demodex mites were found in only one of the patients. This patient, in whom two dead Demodex folliculorums were found through facial sampling, was also regarded as negative since his demodex density was under the threshold limit value. CONCLUSION: In this study, it has been concluded that acne-like rash that develops under the treatment of cetuximab is not related to the presence of demodex mites. Papulopustular eruptions that develop under cetuximab treatment should not be directly correlated with the presence of demodex; first SSSB and demodex presence should be evaluated.

RESUMEN

Cancer is the second leading cause of death and gastric cancer is the fourth most common cancer type worldwide. Investigation of autoantibodies in cancer patients has been a popular research area in recent years. The aim of the current study was to investigate carbonic anhydrase I and II (CA I and II) autoantibodies in the plasma of subjects with gastric cancer based on the information and considerations of autoimmune relation of gastric cancer. Anti-CA I and II antibody levels were investigated by ELISA in plasma samples of fifty two patients with gastric cancer and thirty five healthy peers. Anti-CA I and II antibody titers of the gastric cancer group were significantly higher compared with the control group (p = 0.004, p = 0.0001, respectively). Plasma anti-CA I levels of the metastatic group were lower than the non-metastatic group and this difference was found statistically significant (p < 0.05), but there was no statistical difference between plasma anti-CA II levels of the groups. CA I and II autoantibody titers in patients with gastric cancer were found higher compared to healthy subjects and the results suggest that these autoantibodies may be involved in the pathogenesis of gastric cancer.

RESUMEN

Mucosal melanoma (MM) is a rare type of cancer that differs significantly from cutaneous melanoma. In this study, we aimed to evaluate clinical and demographical characteristics, prognoses and factors influencing survival, treatment alternatives, and features of different subtypes of the patients. The patients were followed up with and treated in different centers due to their diagnoses of MM. We retrospectively analyzed data of 107 patients who were diagnosed with MM in 14 different institutions in Turkey. The mean age of the patients was 64.5 years. Of the patients, 47 % were female and 53 % were male. The median overall survival (OS) was 17 months, and the mean follow-up duration was 27 months. The 2-year survival rate was 42 %, and the 5-year survival rate was 23 %. The best survival rate appeared in those patients with MM in the head-neck region (median survival rate was 27 months, P = 0.034). The most common anatomical site was the head-neck region. In a univariate analysis, variables including age ≥65 years, the anatomical site of the primary lesion other than head and neck region, the metastatic stage of the disease, high levels of lactate dehydrogenase (LDH), and an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of ≥1 were found to be associated with poor survival (P < 0.05). However, in a multivariate analysis, only advanced stage disease (HR = 2.70; 95 % CI, 1.64-4.45; P = 0.000) and high LDH levels (HR = 2.31; 95 % CI, 1.40-3.80; P = 0.001) were determined to be adverse prognostic variables. Primary MM presents a more aggressive behavior and offers a poorer prognosis compared to cutaneous melanoma. Because the disease is rarely seen, is heterogeneous, and lacks randomized studies, issues concerning optimal treatment approaches and management and clinical characteristics of the disease have not been clarified yet.

RESUMEN

BACKGROUND: Approximately 75 % of patients with testicular seminoma present with stage I disease, and the probability of long-term survival approaches 100 %. However, the standard adjuvant treatment for stage I seminoma patients remains controversial, and there is no uniform consensus in the literature. The present study was performed to evaluate treatment preference and outcomes for men with stage I testicular seminoma. MATERIALS AND METHODS: From 1997 to 2013, 282 patients with histologically confirmed stage IA and IB testicular seminoma who underwent orchiectomy were included. The outcomes of three management options and survivals were retrospectively analyzed. The prognostic significance of risk factors for relapse on survival was evaluated by univariate and multivariate analysis; in addition, the factors predicting relapse were also evaluated by logistic regression analysis. RESULTS: Of the 282 patients with stage I seminoma, 130 (46.1) received adjuvant radiotherapy (RT), 80 (28.4 %) were treated with adjuvant carboplatin, while the remaining 72 patients (25.5 %) underwent surveillance. At the time of analysis, the median follow-up period of 38.5 months; relapses were observed in 16 patients (22.3 %) on surveillance, in one patient (1.2 %) treated with adjuvant carboplatin and in ten patients (%7.7) who received adjuvant RT. The 5-year disease-free survival (DFS) rate for patients who underwent surveillance was worse than those of patients treated with adjuvant carboplatin and RT (64.2 vs. 97.7 vs. 91.9 %, respectively; p < 0.001). However, the 5-year overall survival (OS) rate for patients on surveillance was similar compared with the adjuvant treatment groups (100 vs. 92.3 vs. 97.4 %, respectively; p = 0.44). Univariate analysis showed that only the treatment approach (surveillance vs. adjuvant carboplatin vs. adjuvant RT) for DFS (p < 0.001), invasion of the rete testis (p = 0.041) and the presence of relapse (p < 0.001) for OS were important prognostic indicators. Multivariate analysis indicated that the treatment strategy for DFS (p < 0.001, HR 0.34) was an independent prognostic factor. Furthermore, a logistic regression analysis showed that adjuvant treatment was found to be an independent factor for predicting relapse (p = 0.004, odds ratio: 0.39). CONCLUSIONS: Our results indicate that adjuvant treatment with carboplatin or RT is associated with improved DFS compared with surveillance for men with stage I testicular seminoma after orchiectomy. Moreover, the treatment strategy is an important prognostic indicator for DFS and a predictive factor for relapse. Although adjuvant treatment, especially carboplatin, seems to be a suitable treatment for patients with risk factors for relapse, surveillance is still feasible and the preferred management option after radical orchiectomy in men with stage I seminoma. More reliable predictive factors are needed to make treatment decisions.

RESUMEN

Breast cancer (BC) is the most common cancer among women and a major cause of death. Signal Peptide-Cub-Epidermal growth factor domain-containing protein-1 (SCUBE1) is secreted under hypoxia and inflammatory conditions from platelet alpha granules. Its biological function is uncertain, although it may be a procoagulant substance in cancer patients. SCUBE1 is useful for identifying thrombotic diseases, including cancers and acute coronary syndromes. D-dimer reflects the relationship between coagulation activation and fibrinolysis; namely, thrombosis and D-dimer levels are closely linked. This is the first investigation of the potential diagnostic and prognostic value of SCUBE1 levels in patients with BC. Fifty patients and 33 age-matched and body mass index-matched healthy controls were enrolled. Blood samples were collected before chemotherapy regimens commenced. Serum SCUBE1 and D-dimer levels were measured before adjuvant chemotherapy and were compared to the healthy controls. SCUBE1 levels were determined using an enzyme-linked immunosorbent assay (ELISA) method. SCUBE1 and D-dimer levels were significantly higher in patients than in the controls (p = 0.03 and p < 0.001, respectively). A cut-off value of 1.55 ng/mL for SCUBE1 was associated with 62% sensitivity and 72.7% specificity and with positive predictive value of 77.5% and negative predictive value of 55.8%. Two patients with high SCUBE1 and D-dimer levels also developed pulmonary embolism. SCUBE1 may indicate hypercoagulability in patients with BC and thus help identify patients at greater risk of thrombosis and requiring anti-thrombosis treatment. SCUBE1 may also be used as an assistant test for identifying patients at risk of BC.

RESUMEN

PURPOSE: To develop a large Turkish National Melanoma registry in order to define demographic and clinicopathologic characteristics of patients with melanoma. METHODS: The data was collected from 1635 patients with melanoma through a web-based registry system in 22 centers. Herein we present the results of 1157 patients with cutaneous melanoma. RESULTS: The patient median age was 56.4 years and 646 (55.8%) were males. The commonest subtype was superficial spreading type (357, 30.9%). The commonest primary site was the lower extremities (N=353, 30.5%). The most common Breslow thickness was 1-2 mm (361 patients, 43.5%). Only 104 (12.5%) patients had a thickness <1mm. Among 694 patients with available data, 136 (19.6%) presented with stage 4 disease while the most frequent stage was stage 3, encountered in 393 (56.6% patients). CONCLUSION: Our melanoma registry is the largest in our country providing a snapshot view of cutaneous melanoma and its care. Our patients presented with more advanced stages and they had worse prognosis compared to SEER database.

RESUMEN

PURPOSE: Gastric cancer is the most frequent digestive system cancer in Turkey. The purpose of this study was to investigate the effect of sociodemographic, environmental, dietary and reproductive factors on the development of this malignancy. METHODS: 150 patients diagnosed with gastric cancer and 300 healthy controls were included in the present study. Sociodemographic, environmental, dietary and reproductive factors that might affect the risk of gastric cancer were retrospectively investigated. RESULTS: Examination of the dietary menus revealed that consumption of animal fats, pickled and salted foods were considerably higher (p<0.001) in gastric cancer compared to controls. Consumption of meat and eggs were significantly different (p=0.048) between gastric cancer patients and the control group. Consumption of bread and cereal products (p<0.001), milk and milk products (p<0.001), orange juice (p=0.022), tea and coffee (p=0.004 and p=0.002) was markedly lower in the gastric cancer patients. Consumption of pickles was an independent risk factor for development of gastric cancer. Eating too hot foods and barbecued meat was also shown to increase the risk of gastric cancer (p<0.001). In addition, the educational level of the patients was also lower compared to those of the control group (p=0.033). Women with onset of menarche at 15 years and above also possessed a higher risk for gastric cancer (p<0.001). CONCLUSION: Environmental and dietary factors play a significant role in the development of gastric cancer.

RESUMEN

The relation between cancer and coagulation is the subject of investigation since a relation between tumor and thrombosis has been determined. Antithrombin III is an important thrombin inhibitor, and increased thrombin-antithrombin (TAT) complex levels activate coagulation. Activated thrombin activatable fibrinolysis inhibitor (TAFI) inhibits the conversion of plasminogen to plasmin. In addition, it directly inactivates plasmin. Defective fibrinolysis increases the risk of thrombosis. In this study, we evaluated homeostatic parameters, TAFI, and TAT levels in patients with gastric cancer applying to the medical oncology outpatient clinic. Fifty-two patients and 35 healthy controls were included. ELISA was used to measure TAFI and TAT complex levels. These were statistically higher in the patient group (p < 0.05 and p = 0.001, respectively). D-dimer levels were higher in stage IV (p = 0.05). Correlations between lymph nodes and TAFI and TAT levels were examined. Weak but positive correlation between lymph nodes and TAFI was detected (R = 0.452, p = 0.027). TAFI and TAT levels were evaluated using relative operating characteristic analysis to differentiate the disease. TAT was more specific than TAFI according to this analysis (TAFI area under curve (AUC), 0.676; TAT AUC, 0.874). Thrombotic events and bleeding disorders need to be borne in mind in gastric cancer. This situation is due to the impairment of the balance between coagulation and fibrinolysis. Further studies are now needed to evaluate the effects of TAFI and TAT on survey and prognosis as well as the potential of these parameters as tumor markers for gastric cancer.

RESUMEN

AIM OF THE STUDY: Bone is a common site of metastasis in patients with breast cancer. Skeletal complications associated with bone metastasis are commonly treated with bisphosphonates. However, there are a number of side-effects associated with these, such as renal failure, hypocalcemia and osteonecrosis of the jaw. We aimed to determine the effects of ibandronic and zoledronic acid on serum creatinine (SCr), calcium (Ca), phosphorus (P), alkaline phosphatase (ALP) and estimated glomerular filtration rates (eGFR). The objective was to determine the safety of these bisphosphonates, especially zoledronic acid. MATERIAL AND METHODS: Forty-one patients diagnosed with breast cancer (all with bone metastasis) were enrolled. We retrospectively evaluated bisphosphonate type, duration of treatment, infusion time and the parameters SCr, Ca, P, ALP and eGFR. RESULTS: Nineteen patients were included in the zoledronic acid group and 22 in the ibandronic acid group. Mean age in the ibandronic acid group was 53.27 ±11.01, and 53.26 ±9.98 in the zoledronic acid group. Median duration of administration in the ibandronic acid group was 11 (7-37) months, and 10 (7-57) months in the zoledronic acid group. SCr levels did not change significantly during the study period. Pre- and post-treatment Ca levels were also unchanged, but serum ALP levels in the ibandronic acid group and P levels in the zoledronic acid decreased after the final administration; eGFR was unchanged by the end of the study. CONCLUSIONS: Zoledronic and ibandronic acid are safe modalities in the treatment of skeletal events in breast cancer patients with bone metastasis.

RESUMEN

PURPOSE: Plexin C1 is a transmembrane receptor and plexin C1 overexpression might have role in carcinogenesis. Hepatocellular carcinoma (HCC) has poor prognosis because of its aggressive behavior and limited treatment options, especially in advanced stage. We recently documented that Plexin C1 was overexpressed in HCC. We aimed to evaluate the prognostic significance of Plexin C1 overexpression in HCC in the present study. METHODS: Plexin C1 overexpression was evaluated immunohistochemically on paraffin-embedded blocks of the HCC patients. Plexin C1 immunohistochemical staining was scored. Plexin C1 overexpression staining intensity and prevalence were used for plexin scale staining evaluation and plexin scores were estimated according this staining scale. Plexin C1 score and its association with survival and clinicopathological features was assessed. RESULTS: Sixty-seven HCC patients with adequate tissue for pathological evaluation were included. Median age was 63 years with male predominance (male to female ratio was 4.75 (n 57/12). Well-differentiated HCC (53.7%) patients had higher plexin C1 overexpression (p < 0.05). Median OS was 22.1 months. Patients with lower plexin C1 score (< 12) had shorter OS (17.5 vs 30.1 months, p = 0.036). Neutrophil count, GGT, and PNR (platelet/neutrophil ratio) had prognostic significance (p = 0.047, p = 0.018, and p = 0.045). CONCLUSION: Plexin C1 overexpression is inversely correlated with grade in HCC. The patients with lower rate of Plexin C1 overexpression have worse survival outcome. It might be a prognostic factor in HCC.

RESUMEN

BACKGROUND: Merkel cell carcinoma (MCC) is a rare but highly aggressive neuroendocrine carcinoma of the skin. In this study, we aimed to evaluate the clinicopathologic characteristics, treatment outcomes, and survival of MCC cases in Turkey. MATERIALS AND METHODS: The patients diagnosed with MCC between 1999 and 2018 at twenty different centers in Turkey were included in the study. Patient and tumor characteristics and adjuvant and metastatis treatment outcomes were analyzed retrospectively. RESULTS: The median age of totally 89 patients was 70 (26-93). The most common primary location was lower limbs (n = 29, 32.5%). Immunohistochemically, CK20 positivity was present in 59 patients (66.3%). Only two patients had secondary malignancy. The majority of the patients (n = 76, 85.4%) were diagnosed at the localized stage. Surgery was performed for all patients in the early stage, and adjuvant radiotherapy or/and chemotherapy was applied to 52.6% (n = 40) of nonmetastatic patients. The median follow-up was 29 months. Recurrence developed in 21 (27.6%) of the 76 patients who presented with local or regional disease. Two-year disease-free survival (DFS) was 68.1% and 5-year DFS was 62.0% for localized stage. The 5-year DFS was similar for patients receiving adjuvant treatment (chemotherapy, radiotherapy, or sequential chemoradiotherapy) and without adjuvant therapy (P > 0.05). Two-year overall survival in patients who presented with localized disease was 71.3% and 18.5% in metastatic patients (P < 0.001). In the metastatic stage, platinum/etoposide combination was the most preferred combination regimen. Median progression-free survival (PFS) in first-line chemotherapy was 7 months (95% confidence interval: 3.5-10.5 months; standart error: 1.78). CONCLUSIONS: Although MCC is rare in Turkey, the incidence is increasing. Gender, CK20 status, tumor size, lymph node involvement, and adjuvant treatment were not associated with recurrence.

RESUMEN

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. GISTs are believed to be related to mutational activation of receptor tyrosine kinases, KIT, or platelet-derived growth factor receptor-alpha. The coexistence of GISTs with other neoplasms has been extensively addressed in the literature. The most common second neoplasms are colorectal cancer, prostate cancer, and neoplasms derived from lymphoid tissue. In this case report, we describe a patient affected by GIST and acute myeloid leukemia preceded by myelodysplastic syndrome with refractory anemia. The clinicopathological characteristics of the patient are discussed and the literature is reviewed.

RESUMEN

Clear cell hidradenoma is a rare skin appendage tumor. A 41-year-old female presented with right gluteal mass. Excisional biopsy of the mass was performed. Under the epidermis, an eosinophilic-cytoplasm, uniform-appearance, oval-round-nucleus, benign tumor with cystic and solid components was detected. These results were consistent with clear cell hidradenoma. The patient had not been given postoperative adjuvant treatment and has been under follow up free from disease for 2 years.

RESUMEN

BACKGROUND: Melatonin has been suggested to have antiproliferative effects on cancer cells. These effects can be attributed to immunomodulation, growth factor inhibition, induction of apoptosis and prooxidant properties. Melatonin is considered as a safe drug with minimal adverse effects. OBJECTIVES: We planned to investigate the effects of melatonin in hepatoma (Hep G2) cell line. In this study, different concentrations of melatonin were studied to assess its effects on human hepatoma (Hep G2) cell line in vitro. METHODS: In this study, different doses (5 x 10(-5) M, 5 x 10(-4) M, 10(-3) M) of melatonin were administered into hepatocellular carcinoma cell line in vitro. After an incubation period of 72 hours, the studied and control groups were evaluated for cell cycle, morphology, proliferating index and apoptosis percentage. RESULTS: A significant decrease in percentage of phase G0/G1 cells was found in high-dose melatonin group (10(-3) M) compared to control group. Melatonin increased the cell counts in S phase of cell cycle at high doses as well. However, phase G2/M cell percentage did not change with the administration of melatonin. Cell proliferation was increased in all melatonin groups, but the only statistically significant difference was found between the high-dose and control groups. There was a significant increase in proliferative index between the control group and high-dose melatonin group. CONCLUSION: High dose of melatonin increases the cell count in S phase and shows an antiproliferative effect on hepatoma cells. This indicates that melatonin can be considered a promising drug when used along with other antineoplastic agents for the treatment of hepatoma.However, it has no effect on apoptosis and colony counts (Tab. 1, Fig. 2, Ref. 19).

RESUMEN

OBJECTIVE: To present a case of endobronchial metastasis from a seminoma mimicking a primary pulmonary mass on X-ray radiograph. CLINICAL PRESENTATION AND INTERVENTION: A 27-year-old man presented with a 1-month history of hemoptysis. Thorax computerized tomography of the patient obtained at the level of the main right bronchi demonstrated a mass with a size of 7 x 6 cm and a peripheral lobulated nodule. Bronchoscopic examination showed narrowing and multiple nodules in the right upper and right intermediary lobar bronchi. Histopathological examination of bronchial biopsies and brushing confirmed endobronchial metastasis of the testicular seminoma. CONCLUSION: This case shows the prognostic significance of distinguishing endobronchial metastasis from primary lung carcinoma.

RESUMEN

OBJECTIVE: Studies have investigated expression status of galectin-3 (Gal-3), but very little is known about the importance of circulating Gal-3 in patients with breast cancer (BC). The purpose of the study was to investigate the clinical significance and potential diagnostic value of plasma Gal-3 levels in patients with BC. MATERIALS AND METHODS: Fifty-two patients with BC and 35 age-matched healthy controls were enrolled. Levels of Gal-3 were investigated in BC patients and healthy controls. Gal-3 levels were determined using ELISA method. RESULTS: Serum Gal-3 levels were significantly higher in BC patients than in controls (P = 0.002). Gal-3 levels did not significantly differ according to patients' statuses of lymph node involvement, hormone receptor, lymphovascular invasion, e-cadherin, menopausal, stage, serum hemostatic markers (prothrombin time, partial thromboplastin time, and international normalized ratio), platelet counts, mean platelet volume, lactate dehydrogenase, carcinoembryonic antigen, and carbohydrate antigen 15-3 values (P > 0.05 for all). A cut-off value of Gal-3 to predict BC was determined at ≥3.17 ng/ml with a sensitivity of 75.0%, a specificity of 65.71%, a positive and negative predictive values of 76.5 and 63.9%, respectively (area under the curve: 0.705 [95% confidence interval, 0.598-0.798], P = 0.0002). CONCLUSION: Serum Gal-3 levels were significantly higher in BC patients and did not significantly differ according to clinical and tumoral characteristics of patients. Furthermore, there was no difference in Gal-3 levels between BC patients with and without metastatic disease. Serum Gal-3 levels can be used as an adjunct to other diagnostic or screening tests for BC regardless of clinical and tumoral characteristics of patients.

RESUMEN

INTRODUCTION: Breast cancer mortality rates after metastasis is high. Urokinase plasminogen activator receptor (uPAR) and carbonic anhydrase IX (CAIX) play very important roles during tumor cell invasion and metastasis. The purpose of this study was to evaluate plasma levels of uPAR and CAIX and the effect of anthracycline-based chemotherapy on these biomarkers in patients with operable breast cancer. MATERIALS AND METHODS: Sixty-five patients and 25 age-matched healthy controls were enrolled. Levels of uPAR and CAIX were investigated before and after adjuvant chemotherapy. Basal (prechemotherapy) uPAR and CAIX levels in patients were compared with those in healthy controls and in patients after 3 cycles of chemotherapy. Levels of uPAR and CAIX were determined using the ELISA method. RESULTS: uPAR and CAIX levels were significantly higher in patients (P: 0.02 and P: 0.03, respectively). Postchemotherapy uPAR and CAIX levels were higher than basal levels (P: 0.645 and P < 0.001, respectively). A cut-off value of 27.99 pg/mL for uPAR was associated with 45.31% sensitivity and 84.62% specificity, and with a positive predictive value (PPV) of 87.9% and a negative predictive value (NPV) of 38.6%. A cut-off value of 777.84 pg/mL for CAIX was associated with 90.62% sensitivity and 30.77% specificity, and with a PPV of 76.3% and an NPV of 57.1%. CONCLUSION: We determined that uPAR and CAIX levels were higher in the fluorouracil, epirubicin, and cyclophosphamide (FEC) chemotherapy group than in the control group, but there was no difference between the FEC and epirubicin/adriamycin chemotherapy groups in terms of basal and postchemotherapy uPAR, CAIX levels. Furthermore, uPAR is more specific, and CAIX is more sensitive in the diagnosis of breast cancer.

RESUMEN

BACKGROUND: Needs based biopsychosocial distress instrument for cancer patients (CANDI) is a scale based on needs arising due to the effects of cancer. OBJECTIVES: The aim of this research was to determine the reliability and validity of the CANDI scale in the Turkish language. PATIENTS AND METHODS: The study was performed with the participation of 172 cancer patients aged 18 and over. Factor analysis (principal components analysis) was used to assess construct validity. Criterion validities were tested by computing Spearman correlation between CANDI and hospital anxiety depression scale (HADS), and brief symptom inventory (BSI) (convergent validity) and quality of life scales (FACT-G) (divergent validity). Test-retest reliabilities and internal consistencies were measured with intraclass correlation (ICC) and Cronbach-α. RESULTS: A three-factor solution (emotional, physical and social) was found with factor analysis. Internal reliability (α = 0.94) and test-retest reliability (ICC = 0.87) were significantly high. Correlations between CANDI and HADS (rs = 0.67), and BSI (rs = 0.69) and FACT-G (rs = -0.76) were moderate and significant in the expected direction. CONCLUSIONS: CANDI is a valid and reliable scale in cancer patients with a three-factor structure (emotional, physical and social) in the Turkish language.

RESUMEN

INTRODUCTION: Increased thromboembolic disorders and chemotherapy-induced thromboembolic events are well known phenomena in patients with breast cancer. Antithrombin III (AT III) inactivates thrombin, resulting in increased thrombin-antithrombin (TAT) levels. Activated factor X cleaves prothrombin and thrombin, resulting in increased levels of prothrombin fragment 1+2 (F 1+2). Increased TAT and F 1+2 levels show coagulation activation. The aim of this study was to examine plasma levels of TAT and F 1+2 and the effect of anthracycline-based chemotherapy on plasma TAT and F 1+2 in patients with operable breast cancer. MATERIALS AND METHODS: Seventy patients and 30 age-matched healthy controls were enrolled. Levels of TAT and F 1+2 were investigated before and after adjuvant chemotherapy. Basal levels (pre-chemotherapy) of TAT and F 1+2 in patients were compared with those in healthy controls and patient levels after 3 cycles of chemotherapy. Levels of TAT and F 1+2 were determined using the ELISA method. RESULTS: TAT and d-dimer levels were significantly higher in patients, (P: 0.02 and P<0.001, respectively). Post-chemotherapy F 1+2 levels were higher than basal levels (P: 0.02). F 1+2 levels were higher in patients, although the difference was not statistically significant (P: 0.52). There was no difference between basal and post-chemotherapy TAT levels. DISCUSSION: In conclusion, while higher post-chemotherapy F 1+2 levels suggest that the cumulative effect of chemotherapy increases the risk of thrombosis, TAT and d-dimer levels indicate that the effect of the cancer further increases the risk of thrombosis in patients with operable breast cancer.
