Cancer patients who start receiving chemotherapy have difficulty in understanding the state of their disease, the prognosis, and the purpose of treatment. We used a survey to evaluate the extent of perception of chemotherapy goal among cancer patients. Two hundred sixteen cancer patients who received chemotherapy for the first time participated in the study. The presence of depression and anxiety was assessed using the "Hospital Anxiety and Depression Scale" (HAD). The consistency between the patients' perception of the chemotherapy goal and the physician's perception was described as "right," and the inconsistency was described as "wrong." Among the patients who participated in the survey, 53.2 % (n = 115) were receiving adjuvant treatment and 46.8 % (n = 101) were receiving palliative treatment for metastatic disease. The rate of right and wrong perception of the chemotherapy goal was 51.9 % (n = 108) and 32.2 % (n = 67), respectively, and the rate of confused patients was 18.9 % (n = 41). The level of education was shown to be the only parameter involved in accurate perception of the treatment purpose (hazard ratio (HR) = 0.444, p = 0.025, 95 % confidence interval (CI) 0.219-0.903). In this study, there was a 51.9 % consistency between the physician's perception and that of the patient regarding the purpose of treatment. We demonstrated that the level of education was the unique factor in accurate perception of chemotherapy goal among cancer patients.

Aim: The aim of the present study was to evaluate the effect of crizotinib on visceral organs in an experimental rat model., Methods: Eighteen Wistar albino rats were divided into three groups: experimental toxicity was induced with crizotinib (10 mg/kg) administered for 28 days (Group 1), 42 days (Group 2) orally by gavage. Control group received only distilled water. Rats in Group 1 and Group 2 were sacrificed after the collection of blood and tissue samples on the 28th and 42nd days, respectively., Results: Subjects in Group 1 and Group 2 had abnormal histology mainly in lung and liver. There were intraalveolar hemorrhage in lungs; mild portal inflammation, perivenular focal and confluent necrosis in liver; inflammatory reaction in renal pelvis and periureteral areas, and focal pancreatitis in pancreas., Conclusion: This study is the first to evaluate the histopathological features of toxicity of crizotinib in a rat model.

Background: Gastric cancer is the second most common cause of cancer-related death in the world, and its prognosis remains poor with a median overall survival of 12 months for advanced disease. Advances in the understanding of molecular genetics have led to the development of directed molecular targeted therapy in gastric cancer, leading to improve patient outcomes and quality of life., Discussion: In the treatment of human epidermal growth factor receptor 2 (HER2)-positive gastric cancer, the addition of trastuzumab significantly improves survival in the first-line setting of therapy. Ramucirumab, an antibody directed against vascular endothelial growth factor receptor 2, significantly improved progression-free and overall survival and has been approved for second-line treatment of gastric cancer. Anti-mesenchymal-epithelial transition (c-MET), mammalian target of rapamycin inhibitors, and polo-like kinase 1 inhibitors are under investigation as a novel therapeutic option for the treatment of gastric cancer. The novel therapies target the key immune checkpoint interaction between a T cell co-inhibitory receptor called programmed death 1 (PD-1) and one of its immunosuppressive ligands, PD-L1. This article reviews molecular targeted therapies in gastric cancer, in light of recent advances.

Background: In this retrospective study, we aimed to evaluate the clinicopathological characteristics of the patients presenting with liver metastases from unknown primary site besides survival rates, treatment outcomes, and prognostic factors., Methods: In all, 68 patients followed-up at our center with adenocarcinoma of unknown primary (ACUP) metastatic to the liver between 2005 and 2013 were enrolled. All of the liver metastases were proven by liver biopsy and all yielded diagnosis of adenocarcinoma., Results: Median age was 61 years (29-90) and most of the patients were male (male/female: 43/25). The liver was the only metastatic site in 2 (3%) patients whilst 66 patients (97%) had extrahepatic metastases. The most common extrahepatic metastatic sites were lymph nodes (89.7%), lungs (32.4%), bones (25%), peritoneum (11.8%), brain (4.4%), and adrenal glands (2.9%). Of all 68 patients, 39 (57.4%) were treated with chemotherapy. Median overall survival (OS) was significantly higher in ACUP patients treated with chemotherapy [12.5 months (95% CI 8.3-16.7) vs. 4 months (95% CI 1.2-6.8), (p = 0.026), respectively]. In multivariate analysis, ECOG (Eastern Cooperative Oncology Group) performance status (p = 0.009), chemotherapy (p = 0.024), serum albumin (p = 0.012), and serum CA 19-9 level (p = 0.026) at initial diagnosis were identified as independent prognostic factors influencing survival for the patients with liver metastases from ACUP., Conclusion: Patients with liver metastases from ACUP have poor prognosis and chemotherapy improves survival. Decreased serum albumin level, increased CA 19-9 level and poor performance status are independent poor prognostic factors.

The identification of prognostic factors in patients with renal cell carcinoma (RCC) represents an area of increasing interest. In this retrospective study, we evaluated the prognostic role of carbonic anhydrase-IX, ezrin, and neuropilin in metastatic RCC patients. The expression of several biomarkers were measured by immunohistochemistry (IHC) in 45 patients with advanced stage RCC treated with second-line tyrosine kinase inhibitors (TKIs) targeting vascular endothelial growth factor (VEGF) after failure of interferon-alpha between January 2007 and June 2012. Kaplan-Meier curves and log-rank tests were used for analysis of progression-free survival (PFS) and overall survival (OS), and a multivariate Cox proportional hazard model was employed to identify factors with an independent effect on the survival. Age, ezrin and neuropilin-2 overexpression were found to be statistically significant factors (P < 0.05) for PFS in the univariate analysis. Ezrin and neuropilin-2 overexpression, hemoglobin and albumin level were statistically significant factors (P < 0.05) for OS in the univariate analysis. Multivariate analysis revealed that low expression of ezrin and neuropilin-2 was an independent prognostic factor for PFS and OS. The median PFS was 4 months for patients overexpressing neuropilin-2 versus 11 months for those with lower expression of neuropilin-2 (p = 0.033). The median OS was longer in patients with low levels of neuropilin-2 expression (26 months) compared to patients overexpressing neuropilin-2 (13 months) (p = 0.023). Increased expression of ezrin was associated with poor prognosis in patients treated with TKIs targeting VEGF (PFS, 3 vs 7 months; p = 0.012). High ezrin expression was associated with shorter OS (p = 0.009). This is the first study in the literature showing that neuropilin-2 and ezrin are related with prognosis in patients with advanced RCC.

Background: In this study, we investigated the rate of human epidermal growth factor receptor 2 (HER2) overexpression in gastric (GC) and gastroesophageal junction cancers (GEJCs) and the relationship with HER2 expression and clinical, pathological parameters and prognosis., Methods: Surgery or biopsy specimen of 598 (436 males, 162 females) patients with GC or GEJC was evaluated for the presence of HER2 overexpression by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) methods., Results: HER2 IHC scores were as follows: 418 (69.9%) IHC 0, 58 (9.7%) IHC 1+, 50 (8.4%) IHC 2+, 72 (12%) IHC 3+. Among 50 patients with IHC 2+, 18 (38.2%) were FISH positive, and 29 (61.7%) were FISH negative for HER2 amplification. Patients were regarded as HER2 positive in case of IHC 3+ disease or IHC 2+ disease with a positive FISH test result for HER2 amplification. In the primary analysis population, 90 (15%) were considered HER2 positive. HER2 positivity was higher in intestinal GC compared to diffuse GC (16.9 vs 6.6%, p = 0.014). HER2 positivity was significantly higher in well and moderately differentiated tumors than poorly differentiated tumors (p < 0.0001). HER2 positivity had no significant effect on median OS (23.2 vs 19.1 months, p = 0.44). But in the early stages (stages I and II), median OS of HER2-positive patients was shorter than HER2-negative patients (51.4 months vs not reach, p = 0.047). However, median OS was similar in patients with advanced stages (stages III and IV) HER2-positive and HER2-negative disease (16.2 vs 13.7 months, p = 0.72)., Conclusions: Rate of HER2 positivity is similar in Turkish patients with GC and GEJCs. HER2 positivity is associated with poor prognosis in patients with early-stage disease.

Background: We examined the impact of adjuvant modalities on resected pancreatic and periampullary adenocarcinoma (PAC)., Methods: A total of 563 patients who were curatively resected for PAC were retrospectively analyzed between 2003 and 2013., Results: Of 563 patients, 472 received adjuvant chemotherapy (CT) alone, chemoradiotherapy (CRT) alone, and chemoradiotherapy plus chemotherapy (CRT-CT) were analyzed. Of the 472 patients, 231 were given CRT-CT, 26 were given CRT, and 215 were given CT. The median recurrence-free survival (RFS) and overall survival (OS) were 12 and 19 months, respectively. When CT and CRT-CT groups were compared, there was no significant difference with respect to both RFS and OS, and also there was no difference in RFS and OS among CRT-CT, CT and CRT groups. To further investigate the impact of radiation on subgroups, patients were stratified according to lymph node status and resection margins. In node-positive patients, both RFS and OS were significantly longer in CRT-CT than CT. In contrast, there was no significant difference between groups when patients with node-negative disease or patients with or without positive surgical margins were considered., Conclusions: Addition of radiation to CT has a survival benefit in patients with node-positive disease following pancreatic resection.

Objective: Determination of human epidermal growth factor receptor-2 status in advanced gastric cancer is important in clinical decision making. In the trastuzumab for GC trial, trastuzumab-based therapy demonstrated a significant overall survival benefit in patients with human epidermal growth factor receptor-2-positive advanced gastric cancer. Human epidermal growth factor receptor-2 discordance in gastric cancer primary and its metastases has been long debated. The aim of the study was to evaluate the rate of human epidermal growth factor receptor-2 discordance and its effect on treatment decisions in advanced gastric cancer., Methods: A total of 74 patients with advanced gastric cancer were included in the study. Both immunohistochemical staining and dual-color silver in situ hybridization were performed in all patients to evaluate the human epidermal growth factor receptor-2 status of the primary lesion and paired metastasis., Results: The assessment of human epidermal growth factor receptor-2 status with the immunohistochemical staining method and dual-color silver in situ hybridization revealed a discordance rate of 9.5 and 16.2%, respectively. However, this discordance was clinically meaningful in only one patient leading to a change in treatment decision. While this patient had a human epidermal growth factor receptor-2-negative status in primary tumor (immunohistochemical = 0, dual-color silver in situ hybridization = negative), the human epidermal growth factor receptor-2 status was positive for liver metastasis (immunohistochemical = 2+, dual-color silver in situ hybridization = positive). Trastuzumab was added to the chemotherapy regimen., Conclusions: In this study, we found a higher rate of human epidermal growth factor receptor-2 discordance between primary gastric tumor and metastatic lesions compared with the rates reported in previous studies. Detection of a human epidermal growth factor receptor-2-positive metastasis with a human epidermal growth factor receptor-2-negative primary tumor suggests that investigation of human epidermal growth factor receptor-2 is also required for the metastatic lesion and that trastuzumab could be administered in the case of a positive result., (© The Author 2015.

Purpose: The presence of distant metastases (DMs) after the initial treatment of head and neck squamous cell carcinoma is associated with a poor outcome. The incidence of DMs in head and neck cancer is about 4-26%. The purpose of this study was to evaluate the prevalence of distant metastases and the factors predicting the development of DMs., Methods: Between January 2000 and December 2010, 292 patients with head and neck squamous cell carcinoma were included in this study., Results: Thirty three patients (11.3%) developed local recurrences, 27 patients (9.2%) developed DMs. The median post DMs survival was 23.4 months (range 1.8-229.1). The factors that significantly increased the risk of DMs were the presence of local recurrence (p=0.0001, OR:17.32, 95% CI:4.86-19.90), pathologically positive neck (p=0.008, OR:5.97, 95% CI: 3.25-10.45), and primary tumor localized in oral cavity or lip (p=0.035, OR:2.6, 95% CI:1.43-4.65)., Conclusion: Patients with these factors should be considered candidates for adjuvant systemic treatment and evaluated for early detection of DMs during follow-up.

Objective: The objective of this retrospective study is to investigate the association between survival and maximum standardized uptake values (SUVmax) of liver metastases detected by pre-treatment positron emission tomography-computed tomography (PET-CT) in patients with adenocarcinoma of unknown primary origin (ACUP)., Methods: A total of 58 patients with ACUP and liver metastases confirmed histopathologically by liver biopsy and pre-treatment PET-CT were included in this study. SUVmax values of the liver lesions were measured and their association with survival was investigated., Results: The median age was 62 years; 63.8 % of the patients were males and 36.2 % were females. The median overall survival was calculated as 10.7 months (OS). The median SUVmax of the liver metastases was 8.6. Accordingly, two groups were established: one with values <8.6 and the other with ones ≥8.6. No differences were detected between the two groups with respect to general characteristics. Median OS was 13.2 months in the group with SUVmax <8.6 compared to 7.4 months in the group with SUVmax ≥8.6. This difference was statistically significant (p = 0.033). SUVmax (HR 1.104, 95 % CI 1.013-1.204, p = 0.025), age (HR 1.033, 95 % CI 1.002-1.064, p = 0.034), presence of chemotherapy (HR 2.296, 95 % CI 1.136-4.641, p = 0.021) and LDH level (HR 1.002, 95 % CI 1.001-1.003, p = 0.007) were identified as independent prognostic factors affecting survival in the multivariable analysis. This is the first report evaluating the impact of SUVmax for liver metastases on ACUP patient survival., Conclusion: The SUVmax of liver metastases evaluated by PET-CT is a prognostic factor influencing survival of patients with ACUP.

Purpose: The purpose of this study was to evaluate the clinicopathological features of patients with grade III glial tumors associated with recurrence after treatment., Methods: A retrospective analysis was carried out on 67 patients with grade III glial tumors between May 2007 and June 2013. Data were retrieved from patient electronic medical records and paper charts., Results: The patient median age was 43 years (range 19-707 rpar;. Of these, 50.7% (N=34) had anaplastic astrocytoma, 29.9% (N=20) anaplastic oligoastrocytoma and 19.4% (N=13) anaplastic oligodendroglioma. Among these 67 patients, 41 (61.2%) developed local recurrence. Fifty seven of them (80.6%) received radiotherapy (RT) with concomitant temozolomide. Of these patients, 14 (20.9%) received RT with concomitant temozolomide alone, and 43 (64.2%) were treated with concomitant chemoradiotherapy followed by adjuvant temozolomide. Time to recurrence (TTR) of patients who received adjuvant temozolomide after concomitant chemoradiation (TTR=14 months, 95% CI 9.3-22.77 rpar; as initial treatment for grade III glial tumors was not superior to RT with concomitant temozolomide alone (TTR=21 months, 95% CI 14.8-35.2; p=0.224) In multivariate analysis, histologic subtype (p=0.015), age (p=0.019) and presence of neurologic symptoms (p=0.021) were independent predictive factors of recurrence., Conclusion: This analysis demonstrated that histologic subtype, age and presence of neurologic symptoms were significantly associated with recurrence in patients with grade III glial tumors. Adjuvant temozolomide was not significantly associated with recurrence in patients with grade III glial tumors. The identification of these predictors may be important for the patient follow-up and better treatment modifications.

Introduction: We investigated the impact of modern chemotherapy regimens and bevacizumab following pulmonary metastasectomy (PM) from metastatic colorectal cancer (CRC)., Methods: A total of 122 consecutive patients who were curatively resected for pulmonary metastases of CRC in twelve oncology centers were retrospectively analysed between January 2000 and April 2012., Results: Of 122 patients, 14 did not receive any treatment following PM. The remaining 108 patients received fluoropyrimidine-based (n = 12), irinotecan-based (n = 56) and oxaliplatin-based (n = 40) chemotherapy combinations. Among these, 52 patients received bevacizumab (BEV) while 56 did not (NoBEV). Median recurrence-free survival (RFS) was 17 months and median overall survival (OS) has not been reached at a median follow-up of 25 months after PM. Three and five-year OS rates were 66% and 53%, respectively. RFS and OS were similar, irrespective of the chemotherapy regimen or BEV use. Positive pulmonary margin, KRAS mutation status, and previous liver metastasectomy were negative independent prognostic factors for RFS, while pathologically confirmed thoracic lymph node involvement was the only negative independent prognostic for OS in multivariate analysis., Conclusions: No significant RFS or OS difference was observed in respect to chemotherapy regimens with or without BEV in patients with pulmonary metastases of CRC following curative resection.

Purpose: There are no robust data on hemoglobin (Hb), lactate dehydrogenase (LDH), and calcium variability for overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) treated with vascular endothelial growth factor (VEGF)-targeted therapy. We aim to evaluate prognostic implications of Hb, LDH, and calcium variability and establish a novel risk stratification model in RCC patients receiving targeted therapies., Methods: We retrospectively studied an unselected cohort of patients with mRCC, who were treated with tyrosine kinase inhibitors. We assessed LDH variability, Ca variability, and Hb variability with various methods using standard deviation and fluctuation across thresholds. Kaplan-Meier and log-rank analyses were employed on OS and multivariate Cox proportional hazard model analyzed clinical parameters for their prognostic relevance., Results: A total of 59 patients intermediate-risk group according to the Memorial Sloan-Kettering Cancer Center with mRCC who had early progressed after first-line therapy with interferon-α were included in this retrospective single-center study conducted between February 2008 and December 2011. The mean Hb was 12.4 g/dl (min-max 9.1-15.2) throughout the study. Multivariable-adjusted Cox regression showed that patients in the consistently low-Hb group and patients in the low-amplitude and high-amplitude groups had a statistically significant increase in risk compared with patients who were consistently on target (HR 4.1; 95 % CI 1.3-12.9 and HR 2.9; 95 % CI 1.05-8.1 and HR 4.4; 95 % CI 1.7-11.1, respectively). On the other hand, the higher mean LDH (LDH more than 1 >upper limit of normal) was associated with OS. LDH variability and Ca variability were not associated with mortality., Conclusions: In patients with mRCC treated with VEGF-targeted therapy, Hb variability and mean LDH level might be associated with OS. This should be investigated prospectively.

Objective: The objective of this study is to determine whether 2-deoxy-2-[18F] fluoro-D: -glucose with positron emission tomography (FDG-PET) imaging and quantitative PET parameters can predict outcome and differentiate patients with limited disease (LD) from extensive disease (ED) in patients with small cell lung cancer (SCLC)., Methods: We retrospectively evaluated data from 25 patients who underwent either initial staging (Group A, n 12) or restaging (Group B, n 13) by conventional imaging methods and FDG-PET according to the simplified staging scheme developed by the Veterans Administration Lung Cancer Study Group-2. FDG-PET images were both visually and quantitatively evaluated with SUV(max), SUV(ave), total metabolic tumor volume (with SUV(max) > %50 and SUV(max) > 2.5), total lesion glycolysis (TLG) (with SUV(max) > %50 and SUV(max) > 2.5). The correlation between quantitative PET parameters, disease stages and survival were analyzed., Results: By conventional methods 14 of 25 (56%) patients were reported to have LD and 11 of 25 (44%) had ED. FDG-PET scan upstaged 9 out of 25 (36%) and downstaged 2 out of 25 (%8) patients. Among the quantitative PET parameters, TLGs were the only PET parameters that differentiated between Group A and Group B patients. FDG-PET staging (p = 0.019) could predict significant survival difference between stages on contrary to conventional staging (p = 0.055). Moreover, TLG [SUV(max) > %50] was the only quantitative PET parameter that could predict survival (p = 0.027)., Conclusion: FDG-PET imaging is a valuable tool in the management of patients with SCLC for a more accurate staging. The use of quantitative PET parameters may have a role in prediction of stage and survival.

A 29-year-old woman with left pleural effusion and a mass in anterior mediastinum was admitted. Transthoracic needle aspiration from the mass revealed findings consistent with nodular sclerosis variety of Hodgkin's disease. The patient was in remission after six cycles of ABVD followed by mediastinal radiotherapy. Ten months later CT scan showed three hypodense masses in the right kidney. Ultrasound guided renal biopsy revealed diffuse large B cell lymphoma. Retrospective re-evaluation of the archival specimens of the mediastinal mass was also consistent with diffuse large B cell lymphoma. After induction chemotherapy (four cycles of DHAP) she underwent high dose chemotherapy (BEAM) and autologous peripheral blood stem cell transplantation. She is still in remission for 7 years after transplantation. In conclusion, renal involvement during advanced lymphoma is quite common but isolated renal relapse in NHL is a rare situation. Although renal infiltration generally shows a poor prognosis, long-term survival may be achieved with high dose chemotherapy and autologous peripheral blood stem cell transplantation.

Background: Rapid hematological engraftment at autologous peripheral stem cell transplantation (APSCT) is a significant factor in reduction of early transplant-related complications and costs. For this reason, it is important to determine influences on hematological recovery., Methods: This study was designed to evaluate factors affecting leukocyte and platelet engraftment times after high dose chemotherapy following APSCT. A total of 228 patients (131 males and 97 females) were enrolled., Results: There were statistically significant differences between patients with CD34+ cell doses ≥ 2.5 x 10⁶/kg (n=180) and < 2.5 x 10⁶/kg (n=48), regarding leukocyte engraftment at 11 and 12 days, respectively (p<0.02), between G-CSF (n=167) and GM-CSF (n=61) posttransplant regarding median leukocyte engraftment times (p=0.005), and between with (n=75) or without (n=153) history of pretransplant radiotherapy for both leukocyte and platelet engraftment times (p<0.001)., Conclusions: For leukocyte engraftment, a history of pretransplant radiotherapy, type of growth factor used and number of CD34+ cells infused, and for platelet engraftment, a history of pretransplant radiotherapy were found to be independent variables on multivariate analysis with the Cox regression method.

The purpose of this study was to evaluate the validity and reliability of the Barriers Questionnaire II (BQ-II) for Turkish patients and to define the patient-related barriers to cancer pain management in Turkey. For this, 170 patients with cancer who used or were still using analgesic medication for pain related to cancer participated in the study. It was found that patients have beliefs that may be barriers to optimal pain management, mostly in relation to addiction, and to a small extent, physical side effects. It was ascertained that male, unmarried patients, patients with cancer who also have another chronic disease, patients whose "average pain" intensity is more than 5 for the past 24 hours, and patients who use an inadequate analgesic have more beliefs that may be barriers to optimal pain management. It was concluded that the BQ-II is a valid and reliable scale in Turkey for defining patient-related barriers to cancer pain management.

Multiple myeloma (MM) is a malignancy arising from mature plasma cells in the bone marrow and usually presents with bone destruction, hypercalcemia, anemia, renal damage, and increased susceptibility to infection. The etiology of MM is unknown, with no established lifestyle, occupational, or environmental risk factors. Because MM is an uncommon disease, etiologic assessments can be difficult. It has been reported to be in association with sarcoidosis, and in a few cases, rheumatoid arthritis. Familial type of MM with an autosomal dominant heredity pattern has also been reported. The genetic loci affected in these cases are still unknown. Herein we present a family with 3 affected cases in an autosomal dominant inheritance pattern. The first case was a man diagnosed to have immunoglobulin (Ig)A-type myeloma at the age of 50. The history revealed 2 more cases in the family: an uncle diagnosed to have unsecretory-type myeloma at the age of 76 and a cousin (the daughter of the affected uncle) who was diagnosed at the age of 48 years to have IgG-type myeloma and did not respond to therapy. This patient also had a history of sarcoidosis preceding the diagnosis of myeloma. All other affected family members had been treated for dental-oral infection (including chronic gingivitis) for 3 and 4 years before the diagnosis of myeloma. Karyotype analysis revealed pseudohypodiploidy and deletion of chromosome 13q in only the patient with coexisting sarcoidosis. To our knowledge, this is the first report on familial myeloma from Turkey. This family enhances the role of hereditary factors and chronic inflammation in the etiology of MM.

Haploidentical hematopoietic stem cell transplantation (HSCT) is currently one of the alternative curative treatment options for some nonmalignant but also for malignant diseases. However, concerns regarding its safety cause delays in time and a successful outcome. Between 2000 and 2005, twenty-one children with poor prognostic nonmalignant disorders, 13 boys and 8 girls, with a median age of 12 months, underwent 28 haploidentical peripheral HSCT. Immunomagnetic bead depletion device (CliniMACS) was used for indirect T-cell depletion. Indications for transplant were severe combined immunodeficiency (n=16), osteopetrosis (n=2), MDS (n=1), amegakaryocytic thrombocytopenia (n=1), and aplastic anemia (n=1). Five patients (24%) had lung infection at the time of transplantation. The patients received a median of 25.67 x 10(6) G-CSF-mobilized peripheral CD34(+) progenitor cells and a median of 4.19 x 10(4) T-lymphocytes per kilogram of body weight with a T-cell depletion rate of median 4.59 logs. The rate of total engraftment was 66.6%. Median times for leukocyte and platelet engraftment were 14 and 16 days, respectively. The 6-year projected survival was 32% for all patients and 29.76% for patients with severe combined immunodeficiency (SCID). The rates of transplant-related mortality, graft failure, and severe GvHD were 14.2, 33.4%, and 8.3%, respectively. Infection was the main cause of death. The poor outcome may be explained with the poor prognostic factors of our patients such as the type of SCID in most cases (T-B- SCID), the median age over 6 months and the presence of lung infection in some children at the time of transplantation.

Aims and Background: The role of high-dose chemotherapy in breast cancer has not been fully defined. It has been concluded that new trials should focus on defining potential subgroups that are more likely to benefit from high-dose chemotherapy. We compared survival differences in patients receiving human granulocyte-colony stimulating factor (G-CSF) or granulocyte-monocyte colony stimulating factor (GM-CSF) after high-dose chemotherapy with stem cell support., Methods: High-risk non-metastatic breast cancer patients (axillary lymph node involvement more than 8) aged 16 to 65 years and with a performance status < or = 1 underwent high-dose chemotherapy with autograft. Written informed consent was obtained from every patient, and the study was approved by the local ethics committee., Results: For 54 eligible women, the median follow-up was 41.4 months. The five-year disease-free survival was 45.7%. The five-year projected overall survival rate was 53.9%. Among them, patients who received GM-CSF (n = 12) posttransplant lived longer than the patients who received G-CSF (n = 15) (five year survival rates, 46.6% vs 75%, P < 0.050). The patients who received GM-CSF posttransplant had fewer relapses (5 vs 9). However, between the two groups there was no statistically significant difference regarding disease-free survival rates calculated with the Kaplan-Meier method (58.8% vs 40%; P = 0.121)., Conclusions: Patients receiving GM-CSF posttransplant lived longer and they had fewer relapses than those who received G-CSF. This result merits consideration. The antitumor activity of GM-CSF should be investigated further in prospective randomized trials.

Objective: To investigate the impact of c-erb2 status on survival after high-dose chemotherapy., Methods: Between March 1997 and June 2004, a total of 54 women with breast cancer who has at least 8 metastatic lymph nodes underwent high-dose chemotherapy with hematopoietic stem cell transplantation in Gulhane Military Medical School, Ankara, Turkey. Archival specimens were analyzed by fluorescent in situ hybridization to determine the impact of c-erb2 status after peripheral blood stem cell transplantation on survival. The patients were divided into c-erb2 negative (n=20) and positive (n=11) groups., Results: No statistically significant differences were detected between c-erb2 negative and positive groups regarding 5-year disease-free survival (41 and 27%, log rank p=0.11), and overall survival (60 and 45%, p=0.33). Transplant related mortality did not differ between groups., Conclusion: We found no differences between c-erb2 negative and positive groups regarding disease-free and overall survival. To clarify the value of the c-erb2 status in predicting outcome after high-dose chemotherapy, prospective randomized studies are needed.

Purpose/objectives: To determine whether a relationship exists between quality of life (QOL) and the sociodemographic characteristics of gender, age, marital status, educational level, occupation, and level of income in patients with cancer in Turkey., Design: Exploratory study using a convenience sample., Setting: Five hospitals in the capital city of Turkey., Sample: 620 patients with cancer (44 inpatients and 576 outpatients)., Methods: The study was carried out using face-to-face interviews. A questionnaire was used as a tool for collecting data on the sociodemographic characteristics of patients, and the Rolls-Royce Quality-of-Life Scale was employed to measure QOL., Main Research Variables: Gender, age, marital status, educational level, occupation, level of income, and QOL., Findings: Men, older adults, widowed spouses, patients with lower levels of education, housewives, and those with lower income had lower QOL scores., Conclusions: Considering the results and giving the groups referred to in the study priority in the planning of patient care would be useful., Implications for Nursing: In the field of nursing in Turkey, a limited number of studies have examined the relationship between the sociodemographic characteristics of patients with cancer and QOL. The results will help nurses assess patient needs and engage in nursing interventions that are appropriate to the needs.

Breast cancer is the most common malignancy which affects women. In 5-10% of all cases, breast cancer presents as a hereditary cancer syndrome. Since 1996, 68 families with suspicion of familial breast cancer have been referred to our department. In 5 of the 68 families (7.4%), the clinical diagnosis was hereditary breast ovarian cancer syndrome. In 17 families (25%), two or more breast cancer cases were present. Mutation screening of BRCA1 and BRCA2 in these families revealed a BRCA1 mutation (185delAG) in one family. Three families (4.4%) had a diagnosis of Li-Fraumeni syndrome and germline mutations in TP53 (Lys292Ile, Pro278Ser and Pro278Thr). Breast cancer occurred in a family with hereditary nonpolyposis colon carcinoma (HNPCC; Lynch syndrome) carrying an MLH1 mutation (IVS17-3G>C). Most of our families (41 families; 60.2%) had only one case with breast cancer or cystic adenoma (or both) and did not need counseling and DNA testing. In summary, in 10 of the 68 families in our series (14.7%), a germline mutation in a breast cancer predisposing gene was detected. Our data show the importance of detailed examination of clinical data, pedigree analyses, and molecular germline diagnostics for the counseling of breast cancer cases.

Primary cutaneous B-cell lymphomas (PCBCL) are rare and constitute 5-10% of all cutaneous lymphomas. In patients with PCBCL presenting with solitary or localized skin lesions, radiotherapy is the preferred treatment. Two patients who were treated with 4 MeV electrons, both obtained remission for 51 months. Unfortunately, at the last visit one patient relapsed on the border of the radiotherapy field and was re-treated with a generous irradiation field in 2004. Complete response was obtained again. Thus, for localized PCBCL, radiotherapy alone is an effective treatment.

This prospective study was carried out in healthy donors and patients. The performance of the CliniMACS was evaluated with the comparison of the numbers of total nucleated cell (TNC) within and over the capacity of the normal scale column. In addition, large vs. normal scale column and manual vs. automated washing systems were also compared. A total of 44 selections were done. Eighteen normal scale selections were done with initial TNC numbers over 6 x 10(10) and 14 selections were performed below this number. None of the cases had CD34+ cell numbers over the capacity. Flow cytometry was used to check each separation performance for purity and recovery of CD34+ cells along with T- and B-cell depletion level parameters. All healthy donors had significantly better mean purity and recovery of CD34+ cells, and T- and B-cell depletion status than that of patients with values 95 vs. 85%, P: 0.006; 77 vs. 58%, P: 0.004; 4.55 log vs. 4.06 log, P: 0.004; 3.19 log vs. 2.63 log, P: 0.01, respectively. However, the performance of the system was not dependent on using the normal or large-scale column; automated or manual washing systems; and initial TNC numbers above (>6 x 10(10), range: 7.05-21.84 x 10(10), mean: 12.32 x 10(10)) or within (<6 x 10(10), range: 0.86-5.89 x 10(10), mean: 4.15 x 10(10)) the column capacity. In conclusion, the performance of the CliniMACS is more efficient in healthy donors than in patients. However, the performance of the system did not change as long as the numbers of CD34+ cells (range: 0.34-5.87 x 10(8)) were not exceeding the column capacity despite that more than 6 x 10(10) TNCs were used.

In the past, variable results were reported for single daily and two divided daily doses of granulocyte colony-stimulating factor (G-CSF) in stem cell collection where no study exists investigating the effect of body mass index (BMI) on mobilization. The numbers of CD34(+) cells collected were compared in 86 patients with solid or hematological malignancies receiving either single daily (14 mug/kg/day) G-CSF (filgrastim) as group I (n=36) or two divided doses of G-CSF daily (2 x 7 mug/kg/day) as group II (n = 50). Both groups were divided into subgroups according to their BMI as group a (BMI 25 kg/m(2)). Two groups were similar in terms of BMI, gender, and disease characteristics. All patients have received G-CSF as a single or two divided doses subcutaneously and aphereses have been done on the 5th day. No significant difference in numbers of CD34(+) cells between groups Ia and Ib, groups IIa and IIb, and groups Ia and IIa was found. On the other hand, the mean ratio and the number of CD34(+) cells in group Ib were significantly higher than those of group IIb (0.58 +/- 0.06% vs. 0.37 +/- 0.26%, P = 0.01 and 3.67 +/- 0.65 x 10(4)/kg/ml vs. 1.92 +/- 0.37 x 10(4)/kg/ml, P= 0.02). In conclusion, in patients with BMI >25 kg/m(2), once daily G-CSF compared to split dose administration induces a greater number of CD34(+) stem cell mobilization, which suggests the presence of a different pharmacokinetics in obese patients., (Copyright 2003 Wiley-Liss, Inc.)

Objectives: One of the major challenges in the post-transplant period is nutrition. In this prospective, non-randomized study, total parenteral nutrition (TPN) was given to 31 patients and partial parenteral nutrition (PPN) was given to 30 patients undergoing autologous hematopoietic stem cell transplantation for solid tumors or hematologic malignancies to compare the effects of these parenteral nutrition modalities on post-transplant hematological engraftment, blood chemistry, and supportive therapy requirements., Methods: All patients in the TPN group and 17 patients in the PPN group received growth factor in the post-transplant period. Both groups did not differ with respect to sex, age, and reinfused CD34(+) cell numbers., Results: After transplantation body mass index and body weight decreased significantly in both groups (P < 0.001). Whereas serum albumin concentrations did not decrease significantly in the TPN group, it fell markedly in the PPN group at the end of parenteral nutrition (P = 0.019). After parenteral nutrition, blood chemistry was also remarkable for serum urea and glucose levels, which were elevated significantly in the TPN group (P < 0.001 and P = 0.03, respectively). Patients receiving TPN had a higher incidence of positive microbial cultures and clinical infection than did patients receiving PPN (64.5% versus 40%, P = 0.05). The most striking result was a delay in platelet engraftment for the TPN group compared with the PPN group (15.54 and 12.93 d, respectively; P = 0.014). This difference was also noted in patients using growth factor in the PPN group (P = 0.017). Parallel to these results, platelet transfusion requirement increased in the TPN group compared with the PPN group (1.93 versus 1.16 U, P = 0.004). Both groups were unremarkable for leukocyte recovery and red blood cell transfusion requirement., Conclusions: Consequently, TPN has some pitfalls of hyperglycemia, infection tendency, delayed platelet engraftment, and increased platelet transfusion requirement. Therefore, it should not be used as a standard nutrition support for patients undergoing autotransplantation.
