Depression and socio-economical burden are more common in primary caregivers of patients who are not aware of their cancer: TURQUOISE Study by the Palliative Care Working Committee of the Turkish Oncology Group (TOG).

In this study, we aimed to determine the personal, social and economic burden and the frequency of depression, as well as in caregivers of cancer patients who are being treated with chemotherapy in Turkey. The study is designed as a cross-sectional survey study using a 5-point Likert-type response scale, and the last part of the questionnaire includes the Beck Depression Inventory. The depression rate was found to be 64% (n = 476) among all subjects (n = 968), with 91% of those with depression demonstrating signs of mild depression. In this study, a significant difference was found between the presence of depression and age (young), sex (female), educational level (high), economic status (low), financial loss during treatment, patient's lack of knowledge about his/her diagnosis, metastatic disease and short survival time. In addition, 64% of all subjects had concerns of getting cancer, and 44% of all subjects had feelings of anger/rage against other people. In a multivariate regression analysis, the patient's lack of knowledge of the diagnosis was the independent risk factor. In conclusion, depression incidence and burden rate increased among cancer caregivers, and care burden was highly associated with depression. Accordingly, approaches to reducing the psycho-social effects of cancer should focus intensively on both the patients and their caregivers in Turkey.

Outcome of patients with stage II and III nonseminomatous germ cell tumors: results of a single center.

BACKGROUND: The prognostic factors in nonseminomatous germ cell tumors have been mainly derived from the analysis of stage I tumors. AIMS: The aim of this study was to evaluate some prognostic factors and the outcome of patients with stage II and III nonseminomatous germ cell tumors according to risk groups treated between 1993 and 2002. SETTINGS AND DESIGN: Patients were retrospectively classified as good, intermediate and poor risk groups according to International Germ Cell Cancer Consensus Group. MATERIALS AND METHODS: Biopsy specimens of 58 patients with stage II and III nonseminomatous germ cell tumors were analyzed by means of tumor histopathology, primary localization site of the tumor, relapse sites, initial serum tumor marker levels, the presence of persistent serum tumor marker elevation and the patients' outcome. STATISTICAL ANALYSIS: Kruskall Wallis test and Mann-Whitney U test were used to determine the differences between the groups. Kaplan-Meier method was used for survival analysis and log rank test was used to compare the survival probabilities of groups. Cox proportional hazard analysis was used to determine the prognostic factors in univariate and multivariate analysis. RESULTS: Five-year overall and disease-free survival rates were calculated as 85% and 75% in stage II; 44% and 29% in stage III cases, respectively. Fifty-seven percent of patients were classified in good risk, 9% in intermediate risk and 27% in poor risk groups. Five-year overall survival rates were 97%, 75% and 7% (P<0.001) and disease-free survival rates were 83%, 34% and 7% (P<0.001) in good, intermediate and poor risk groups, respectively. Analysis of the prognostic factors revealed that the localization site of the primary tumor (P<0.001), the initial beta-HCG level (p:0.0048), the presence of yolk sac and choriocarcinoma components in tumor (p:0.003 and p:0.004), relapse sites of tumor (lung versus other than lung) (p:0.003), persistent elevation of serum tumor markers (P<0.001) were significant prognostic factors in univariate analysis. However, in multivariate analysis, only the localization site of tumor (p:0.049) and the relapse site (p:0.003) were found statistically significant. CONCLUSIONS: This retrospective study revealed that in advanced stage of nonseminomatous germ cell tumors, the outcome is essentially related with the localization site of the tumor and the relapse site.

Safety and efficacy of transdermal fentanyl in patients with cancer pain: phase IV, Turkish oncology group trial.

We have performed a prospective evaluation of the efficacy, safety and convenience of the transdermal therapeutic system - fentanyl (TTS-F) in Turkish cancer patients when it was newly available in Turkey. Ninety-nine patients with historically confirmed malignancy and pain entered the study; the mean age was 55.1 (16-58) years. The study duration was 28 days. Transdermal therapeutic system - fentanyl was used in opioid-naïve or pre-treated patients. Most patients reported a decrease in pain severity. Use of rescue medication decreased from day 4 to day 28. The majority of patients rated patch convenience of use as excellent. A total of 22.2% of patients experienced adverse events that were either probably related or very likely to be related to the study drug. The majority of the adverse events mentioned were related to the digestive system. Eighteen serious adverse events were reported by 13 patients. Six events were doubtfully related, and 12 events were not related to the study drug. Four patients died during the trial. None of these deaths was attributed to the study drug. In conclusion, the trial showed that TTS-F is easily managed, effective and will help to enable the appropriate opioid administration to patients who are suffering from cancer pain in Turkey.

Cisplatin plus oral etoposide (EoP) combination is more effective than paclitaxel in patients with advanced breast cancer pretreated with anthracyclines: a randomised phase III trial of Turkish Oncology Group.

Our objective was to determine whether oral etoposide and cisplatin combination (EoP) is superior to paclitaxel in the treatment of advanced breast cancer (ABC) patients pretreated with anthracyclines. From December 1997 to August 2003, 201 patients were randomised, 100 to EoP and 101 to paclitaxel arms. Four patients in each arm were ineligible. The doses of etoposide and cisplatin were 50 mg p.o. twice a day for 7 days and 70 mg m(-2) intravenously (i.v.) on day 1, respectively, and it was 175 mg m(-2) on day 1 for paclitaxel. Both treatments were repeated every 3 weeks. A median of four cycles of study treatment was given in both arms. The response rate obtained in the EoP arm was significantly higher (36.3 vs 22.2%; P=0.038). Median response duration was longer for the EoP arm (7 vs 4 months) (P=0.132). Also, time to progression was significantly in favour of the EoP arm (5.5 vs 3.9 months; P=0.003). Median overall survival was again significantly longer in the EoP arm (14 vs 9.5 months; P=0.039). Toxicity profile of both groups was similar. Two patients in each arm were lost due to febrile neutropenia. The observed activity and acceptable toxicity of EoP endorses the employment of this combination in the treatment of ABC following anthracyclines.

Oxidative stress in patients undergoing high-dose chemotherapy plus peripheral blood stem cell transplantation.

Chemotherapy and radiation therapy are associated with increased formation of reactive oxygen species and depletion of critical plasma and tissue antioxidants. In patients undergoing high-dose chemotherapy, the plasma antioxidant concentration has been shown to decrease. However, these studies in which the oxidative stress status were investigated have a small number of patients and they are heterogeneous. In this study, the changes in certain trace elements together with oxidative stress parameters were investigated in 36 patients who had undergone autologous stem cell transplantation because of solid and hematological malignancies. Blood samples of the patients were examined before the high-dose chemotherapy (baseline), before stem cell transplantation (day -1), and after stem cell transplantation on day 1, 3, and 6. Erythrocyte zinc, silver, and iron levels were measured by atomic absorption spectrophotometry; malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) levels were measured by UV-vis spectrophotometry. After high-dose chemotherapy, significant increases in the levels of MDA, GSH-Px, and SOD were observed. On the other hand, Cu levels remained the same while the levels of erythrocyte Zn and Fe were increased. Significant correlation was observed among MDA, GSH-Px, and SOD (p<0.05). High-dose chemotherapy gives rise to an increase in the oxidative stress and the reactive oxygen species. Standard parenteral nutrition protocols were found to be insufficient to lower this stress.

Evaluation of nutritional status in advanced metastatic cancer.

Consecutive cancer referrals to a palliative medicine program were evaluated to assess nutritional status using a standard protocol. The study included 352 patients (180 men, 172 women; median age 61 years, range 22-94 years). The most common diagnosis was lung cancer. All had metastatic disease, 139 with gastrointestinal involvement. The most common gastrointestinal symptoms were weight loss ( n=307), anorexia ( n=285), and early satiety ( n=243). Of those with any weight loss, 71% had lost >or0% of their pre-illness weight. The most common factor identified which might have contributed to weight loss was hypophagia ( n=275/307). Men had lost weight more often and to a greater extent than women. Triceps skinfold (TSF) was measured in 337: 51% had values that suggested severe fat deficiency. Upper mid-arm muscle area (AMA) was measured in 349: 30% had evidence of significant muscle mass reduction. The body mass index (BMI) was normal or increased in most patients. Calculated resting energy expenditure (REE) ( n=324) was high in 41%. C-reactive protein was elevated in 74% of those measured ( n=50). We conclude that: (1).most of this group of cancer patients referred to palliative medicine had severe weight loss; (2).there was a gender difference in the severity and type of weight loss; (3).males lost more weight overall and more muscle than females; (4).males with any degree of weight loss had a higher REE than females; (5).a significant correlation existed between the time from diagnosis to death and the severity of weight loss in the prior month; (6).BMI was normal in most patients, suggesting precancer diagnosis obesity; and (7).both TSF and AMA correlated well with body composition of both fat and protein as determined by bioelectrical impedance.

Survey of the use of complementary and alternative medicine among Turkish cancer patients.

OBJECTIVES: To measure the frequency of use of complementary and alternative medicine (CAM) among patients with malignancy undergoing or following conventional treatment, to determine demographic characteristics associated with the use of CAM, and to find out how benefits, if any, were perceived by patients. DESIGN: A 35-item survey questionnaire administered to 305 return patients with malignancy. SETTING: Clinical wards of the Oncology and Haematology departments of Gülhane Military Medical Academy, Ankara, Turkey. METHODS: Questionnaire-based measures of demographics, motives, expectations and effects of using CAM, and types and reported perceived benefits of CAM practised on patients with malignancy. RESULTS: The majority of return patients (n = 186, 61.0%) used at least one CAM practice; and birthplace, educational status, and family type were significant factors in such behaviour. CONCLUSIONS: Patients with malignancy born in villages, having less education and living in large families were more likely to use folk medicine. More than half of those using CAM (n = 99, 53.2%) reported as benefits the feelings of either strengthening of the body, being in good psychological condition, or the disappearance of several symptoms.

Changes in immunological recovery in patients who received post-transplant G-CSF or GM-CSF after autologous peripheral blood stem cell transplantation (PBSCT).

In this prospective study, the effects of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on immunological reconstitution after autologous peripheral blood stem cell transplantation (PBSCT) were investigated for 6 months. Thirty-five patients received G-CSF 5 microg/kg per day and 26 patients received GM-CSF SC 5 microg/kg per day from day 1 to leukocyte engraftment (>1000 per mm3). Peripheral blood samples were obtained on 14, 28, 100, and 180 days after transplantation for immunological evaluation. CD3+, CD4+, CD8+, CD19+, and CD56+ cells were analysed by flow cytometry. Immunoglobulin levels (IgG, IgA, and IgM) and complement levels (C3c and C4) were measured by nephelometry. Both G-CSF and GM-CSF groups were comparable with respect to age, sex, the period from diagnosis to transplantation, total nucleated cells infused, the number of CD34+ cells, conditioning regimens (TBI and non-TBI), and post-transplant infection. CD3+ and CD8+ cells on day 14 following autologous PBSCT + G-CSF were significantly higher than following autologous PBSCT + GM-CSF (p = 0.008 and p = 0.021, respectively). The number of CD4 cells and the CD4/CD8 ratio were not different at several time points between the two groups. CD19+, CD56+ cells and immunoglobulin levels showed a faster recovery pattern in the autologous PBSCT + G-CSF group. The effect of G-CSF on immune reconstitution after autologous PBSCT is more prominent than that of GM-CSF. The possible role of haematopoietic growth factor on immune recovery and its clinical importance should be investigated in further studies.

Effects of tamoxifen on the serum leptin level in patients with breast cancer.

BACKGROUND: Leptin is a peptide hormone that has a role in the regulation of body weight and has effects on metabolic, neuroendocrine, reproductive and hematopoietic systems. Breast cancer has also been associated with obesity and reproductive hormones, especially estradiol. Only a few studies have investigated the relation between plasma leptin and risk of breast cancer and only one study evaluated the effect of tamoxifen on leptin levels in patients with breast cancer. METHODS: We investigated serum leptin levels in gender-, body mass index (BMI)- and age-matched breast cancer patients and healthy individuals (58 of each). RESULTS: Serum leptin levels were measured by radioimmunoassay (Human Leptin RIA Kit). Serum leptin levels in the breast cancer patients were significantly higher than those in the control group (27.00 versus 17.65 ng/ml, p = 0.019). There were no differences with respect to BMI and age between control and breast cancer patients. There were no significant differences in BMI and leptin levels between pre- and postmenopausal patients (27.00 +/- 1.39 and 27.19 +/- 0.81 kg/m(2), 26.81 +/- 6.25 and 27.06 +/- 2.98 ng/ml) (p > 0.05). We found no difference in serum leptin level between early and late stages of patients (22.38 versus 31.30 ng/ml, p = 0.086). However, the serum leptin level in patients using tamoxifen was significantly higher than that of patients not using tamoxifen (32.71 and 19.39 ng/ml, respectively p = 0.009). There was no correlation between CA 15-3 and leptin level (r = 0.069, p = 0.610). CONCLUSION: High serum leptin levels seen in breast cancer patients are not related to stage of the disease or to cancer itself but may be associated with the use of tamoxifen.

Colon cancer during pregnancy. A case report.

BACKGROUND: The reported incidence of cancer during pregnancy is between 0.07% and 0.1%. The incidence of colorectal carcinoma in pregnancy was 1 per 13,000 liveborn deliveries during 1981-1989. CASE: A 33-year-old woman, gravida 2, para 1, was admitted at 30 weeks' gestational age with a history of rectal bleeding and right upper quadrant pain. Abdominal ultrasound and magnetic resonance imaging revealed a mass located on the posterior part of the right liver and a fetus with vertex presentation. Primary cesarean section and a right hemicolectomy and wedge biopsy from the metastatic lesion on the right side of the liver at 34 weeks' gestation was performed. Histologic examination confirmed serosal and lymph node invasion of moderately differentiated mucous-secreting adenocarcinoma of the cecum and adenocarcinoma metastatic to the liver. The patient received systemic chemotherapy. CONCLUSION: Only 1 of 41 cases of colon cancer during pregnancy above the peritoneal reflection has been reported to be localized to the cecum. Our case is the second such one. Women with colorectal carcinoma during pregnancy usually have a poor prognosis, which may be attributable to younger age and delay in diagnosis since the initial symptoms often are presumed attributed to normal pregnancy, as in this case.

The gastrointestinal symptoms of advanced cancer.

The commonest gastrointestinal (GI) symptoms in advanced cancer are reviewed with reference to definition, pathophysiology, etiology, prevalence, severity, and management. Observation or reporting of such symptoms must lead to consideration of the multi-faceted pathophysiology. Careful assessment and an analytical detailed approach are the keystones of effective management.

The relationship between disease features and quality of life in patients with cancer--I.

The high incidence and the severe symptoms of cancer have a considerable effect on quality of life in patients. The relationship between quality of life in patients with cancer and treatment, early diagnosis, disease acceptance, pain, psychological distress, loss of organ, duration of disease, and caregivers was investigated. This study included 508 patients with cancer treated in either inpatient or outpatient clinics of 5 oncology centers in Ankara, Turkey, between August 1 998 and January 2000. Patients were selected by interviews. Data were collected by a questionnaire to determine disease features and to evaluate patients' quality of life. We found that several disease features, including treatment, early diagnosis, disease acceptance, pain, psychological distress, and caregivers, had an effect on patients' quality of life (P < 0.05), whereas loss of organ and duration of disease did not. The results of this study underline the significant effect of psychosocial care programs on quality of life. In the future, assessments of quality of life can help healthcare personnel to prepare psychosocial care programs.

Plasma and erythrocyte lipid peroxidation levels in patients with testis tumor after orchiectomy.

Plasma and erythrocyte lipid peroxidation levels of 20 patients with histopathologically confirmed testis cancer and 20 healthy control individuals were studied between November 1995 and June 1997. The group with testis cancer had a mean age of 24.8+/-8.2 yr and the control group's mean age was 28.3+/-6.9 yr. Stage distribution of the testis cancer cases were 4 of stage A, 10 of stage B, and 6 of stage C. Blood samples of the patients were drawn after orchiectomy and after 12 h fasting before chemotherapy. Mean plasma and erythrocyte lipid peroxidation levels were detected to be 14.51+/-5.30 nmol malondialdehide (MDA)/mL and 9.30+/-2.06 nmol MDA/g hemoglobin (Hb), respectively, in the testis cancer group, whereas the healthy control group had mean plasma and erythrocyte lipid peroxidation levels of 10.7+/-1.82 nmol MDA/mL and 6.18+/-1.68 nmol MDA/g Hb, respectively. Plasma and erythrocyte lipid peroxidation values of the testis cancer patients were determined to be statistically significantly higher than that of the health control group (p < 0.001, p < 0.001). No significant correlation was determined between plasma, erythrocyte lipid peroxidation levels and tumor markers. In conclusion, it can be said that an increase in the lipid peroxidation may play a role in the pathogenesis of testis carcinomas in addition to the other causes.

Bioelectrical impedance, cancer nutritional assessment, and ascites.

This report describes our experience in the use of bioelectrical impedance analysis (BIA) as a method of nutritional assessment in a cancer patient with ascites. The BIA was an unreliable measure of body composition in this setting.

Recurrent spontaneous pneumothorax following high-dose chemotherapy in a patient with non-seminomatous testicular cancer with pulmonary metastases.

With modern treatment modalities it is possible to obtain a long survival in patients with non-seminomatous testicular cancer. Chemotherapy is the mainstay of treatment in metastatic cases. High-dose chemotherapy and autologous peripheral blood stem cell transplantation is a good salvage treatment for recurrent cases. However, the modality has serious complications. We present a rare case of recurrent spontaneous pneumothorax due to rupture of residual cystic lesions after high-dose chemotherapy in a patient with pulmonary metastases. Such a situation has been rarely reported.

Bilateral male breast cancer and prostate cancer: a case report.

Male breast cancer, consisting only 1% of all breast cancers, is occasionally associated with other primary malignancies, especially in patients with familial breast cancer history. Sporadic male breast cancers with another primary tumor are extremely rare. We report a 67-year-old male with asynchronous bilateral breast cancer and prostate cancer without familial breast cancer history.
