Evaluation of sleep disorders in cancer patients based on Pittsburgh Sleep Quality Index.

Insomnia, poor sleep quality and short sleep durations are the most common problems seen in cancer patients. More studies are needed about sleep disorders in cancer patients. In our study, we aimed to investigate the prevalence of sleep disorders and the impact of these problems on the quality of life in cancer patients. Pittsburgh Sleep Quality Index (PSQI) was given to a total of 314 patients. The psychometric evaluation of the Turkish version of PSQI in cancer patients revealed that 127 (40.4%) patients had global PSQI scores >5, indicating poor sleep quality. There was no statistically significant relationship between PSQI scores and sexuality, marital status, cancer stage and chemotherapy type (P > 0.05); while the patients with bone and visceral metastasis had much lower PSQI scores (P = 0.006). Patients with Eastern Cooperative Oncology Group performance scores of 3 or more had also significantly lower PSQI scores (P = 0.02). In conclusion, PSQI questionnaire may be used to evaluate the sleep disorders in cancer patients. Consistent use of multi-item measures such as PSQI with established reliability and validity would improve our understanding of difficulties experienced by cancer patients with chronic insomnia.

Long-term outcomes and prognostic factors of high-risk malignant melanoma patients after surgery and adjuvant high-dose interferon treatment: a single-center experience.

BACKGROUND: Surgical excision constitutes an important part of the treatment of local advanced malignant melanoma. Due to the high recurrence risk, adjuvant high-dose interferon therapy is still the only therapy used in stage IIB and III high-risk melanoma patients. METHODS: One hundred two high-risk malignant melanoma patients who received high-dose interferon-α-2b therapy were evaluated retrospectively. The clinicopathological features, survival times, and prognostic factors of the patients were determined. RESULTS: The median disease-free and overall survival times were 25.2 and 60.8 months, respectively. Our findings revealed that male gender, advanced disease stage, lymph node involvement, lymphatic invasion, the presence of ulceration, and a high Clark level were significant negative prognostic factors. CONCLUSION: In light of the favorable survival results obtained in this study, high-dose interferon treatment as adjuvant therapy for high-risk melanoma is still an efficient treatment and its possible side effects can be prevented by taking the necessary precautions.

The association of clinicopathological features and survival in colorectal cancer patients with kras mutation status.

BACKGROUND: KRAS mutations have a significant role in the consecutive activation of RAS.RAF.MEK.ERK pathway in colorectal cancer.Approximately 30.35% of sporadic colorectal cancers have KRAS mutation. While the predictive role of KRAS is commonly accepted at the present time, its prognostic role and association with different clinical and histopathological properties are currently unclear and inconsistent. The intent of this study, has been to evaluate the associations between KRAS gene mutations and clinicopathological features and survival times in Turkish colorectal cancer patients. MATERIALS AND METHODS: In this study, the file records of 115 metastatic colorectal cancer patients who applied to the Department of Medical Oncology between 2000 and 2011 were monitored; data on clinicopathological features and survival times were collected. DNA.sequencing method with PCR amplification from archival paraffin blocks were used for KRAS mutation status analysis. The associations between KRAS mutation status and clinicopathological features and survival times were compared statistically. RESULTS: While a significant association hadbeen determined between KRAS mutation status and tumor localization, there was no determined significant association with other clinicopathological properties. Similarly, there was no association between KRAS mutation status and survival parameters. CONCLUSIONS: As a result, the effect of KRAS mutation status on clinicopathological features, survival time and prognosis is unclear.

Clinicopathologic characteristics, treatment outcomes, and prognostic factors of primary thoracic soft tissue sarcoma: A multicenter study of the Anatolian Society of Medical Oncology (ASMO).

BACKGROUND: Soft tissue sarcomas (STSs) are rare malignant tumors of embryogenic mesoderm origin. Primary thoracic STSs account for a small percentage of all STSs and limited published information is available. This study aimed to identify the prognostic factors for thoracic STSs and evaluate the disease's clinical outcomes. METHODS: The medical records of 109 patients with thoracic STSs who were treated between 2003 and 2013 were retrospectively reviewed. Patients' survival rates were analyzed and potential prognostic factors evaluated. RESULTS: The median follow-up period was 29 months (range: 1-121 months). STSs were most frequently localized on the chest wall (n = 42; 38.5%) and lungs (n = 42; 38.5%). The most common histological types were malignant fibrous histiocytoma (n = 23; 21.1%), liposarcoma (n = 17; 15.6%), and leiomyosarcoma (n = 16; 14.7%). The median survival time of all patients was 40.3 months (95% confidence interval, 14.22-66.37 months), with one and five-year survival rates of 93.4% and 63.5%, respectively. Univariate analysis of all groups revealed that metastatic stage, unresectability, tumor diameter of >10 cm, tumor location other than the chest wall, and grade 3 diseases were predictable of poor survival. However, only grade 3 diseases and tumor location other than the chest wall were confirmed by multivariate analysis as poor prognostic factors. CONCLUSIONS: Primary thoracic STSs are rarely seen malignant tumors. Our results indicated that patients with low-grade tumors and those localized on the chest wall often experienced better survival outcomes.

Adult Urological Soft Tissue Sarcomas: A Multicenter Study of the Anatolian Society of Medical Oncology (ASMO).

OBJECTIVE: To analyze clinicopathological characteristics, prognostic factors and survival rates of the patients with urological soft tissue sarcomas treated and followed up in Turkey. MATERIALS AND METHODS: For overall survival analyses the Kaplan-Meier method was used. From medical records, nine prognostic factors on overall survival were analysed. RESULTS: For the 53 patients (34 males, 19 females) whose charts were reviewed, the median age was 53 (range 22 to 83) years. Most frequently renal location (n=30; 56.6%) was evident and leiomyosarcoma (n=20, 37.7%) was the most frequently encountered histological type. Median survival time of all patients was 40.3 (95% CI, 14.2-66.3) months. In univariate analysis, male gender, advanced age (≥50 years), metastatic stage, unresectability, grade 3, renal location were determined as worse prognostic factors. In multivariate analysis, metastatic stage, unresectability and grade 3 were determined as indicators of worse prognosis. CONCLUSIONS: Urological soft tissue sarcomas are rarely seen tumours in adults. The most important factors in survival are surgical resection, stage of the tumour at onset, grade and location of the tumour, gender and age of the patients.

Intra-peritoneal cisplatin combined with intravenous paclitaxel in optimally debulked stage 3 ovarian cancer patients: an Izmir Oncology Group study.

BACKGROUND: The advantage of intra-peritoneal (IP) chemotherapy (CT) in the initial management of ovarian cancer after cytoreductive surgery is well known. The feasibility and toxicity of a treatment regimen with an IP+intravenous CT (IPIVCT) for optimally debulked stage III ovarian cancer were here evaluated retrospectively. MATERIALS AND METHODS: A total of 30 patients were treated in our institution between October 2006 and February 2011. Patients received IV paclitaxel 175 mg/m2 over 3 hours followed by IP cisplatin 75 mg/m2 on day 1; they also received IP paclitaxel 60 mg/m2 on day 8. They were also scheduled to receive 6 courses of CT every 21 days. RESULTS: The median age of the patients was 55 years (35-77), and the majority had papillary serous ovarian cancer (63.3%). The patients completed a total of 146 cycles of IPIVCT. Twenty-eight were able to receive at least three cycles of IPIVCT and 18 (60%) completed the scheduled 6 cycles. Two patients discontinued the IPIVCT because of toxicity of chemotherapy agents and 6 had to stop treatment due to intolerable abdominal pain during IP drug administration, obstruction and impaired access. Grade 3/4 toxicities included neutropenia (6 patients; 20%), anemia (2 patients; 6.7%) and nausea-vomiting (2 patients; 6.7%). Doses were delayed in 12 cycles (8%) for neutropenia (n=6), thrombocytopenia (n=3) and elevated creatinine (n=3). Drug doses were not reduced. The median duration of progression-free survival (PFS) was 47.7 months (95%CI, 38.98-56.44) and overall survival (OS) was 51.7 months (95%CI, 44.13-59.29). Two and five-year overall survival rates were 75.6 % and 64.8%, respectively. CONCLUSIONS: IPIVCT is feasible and well-tolerated in this setting. Its clinically proven advantages should be taken into consideration and more efforts should be made to administer IPIVCT to suitable patients.

Malign recurrence of primary chest wall hemangiopericytoma in the lung after four years: a case report and review of the literature.

Hemangiopericytoma (HPC) may develop in every site where the endothelial tissue exits and primarily develops in the skeletal-muscular system or the skin. Adult cases of HPC generally exhibit a benign course. 20-30% of the cases may show a malign course. The tumors that show more than four mitoses, a focal area of necrosis, and increased cellularity on a magnification ×10 are considered as malign. In our paper, we presented our case who showed a lung metastasis at the end of 4 years and who developed a pathological fracture of the right humerus at the end of approximately 2 years, because hemangiopericytoma is rarely seen in the chest wall as a primary tumor.

Prognostic factors and adjuvant treatments for surgically treated cancers of the biliary tract: a multicentre study of the Anatolian Society of Medical Oncology (ASMO).

BACKGROUND: Biliary tract cancers are rare, and surgical resection is the standard treatment at early stages. However, reports on the benefits of adjuvant treatment following surgical resection are conflicting. This study aimed to evaluate the factors affecting survival and adjuvant treatments in patients with surgically treated biliary tract cancers. MATERIALS AND METHODS: Patient clinical features, adjuvant treatments, and efficacy and prognostic factor data were evaluated. Survival analyses were performed using SPSS 15.0. RESULTS: The median overall survival was 30.7 months (95% confidence interval [CI], 18.4-42.9 months). Median survival was 19 months (95% CI, 6-33) for patients treated with fluorouracil based chemotherapy and 53 months (95% CI, 33.2-78.8) with gemcitabine based chemotherapy (p=0.033). On univariate analysis, poor prognostic factors for survival were galbladder localization, perineural invasion, hepatic invasion, a lack of adjuvant chemoradiotherapy treatment, and a lack of lymph node dissection. On multivariate analysis, perineural invasion was a poor prognostic factor (p=0.008). CONCLUSIONS: Biliary tract cancers generally have poor prognoses. The main factors affecting survival are tumour localization, perineural invasion, hepatic invasion, adjuvant chemoradiotherapy, and lymph node dissection. Gemcitabine-based adjuvant chemotherapy is more effective than 5-fluorouracil-based chemotherapy.

Two-week combination chemotherapy with gemcitabine, high-dose folinic acid and 5 fluorouracil (GEMFUFOL) as first-line treatment of metastatic biliary tract cancers.

BACKGROUND: The aim of this study was to evaluate the efficacy and tolerability of a gemcitabine, 5-fluorouracil and leucovorin (GEMFUFOL) chemotherapy regimen as first line treatment of metastatic biliary tract cancer. MATERIALS AND METHODS: All patients received folinic acid 400 mg/m(2) on day 1, 5-fluorouracil bolus 400 mg/ m2 on day 1, IV infusion of 5-fluorouracil 2400 mg/m(2) over 46 hours, and gemcitabine 1250 mg/m(2) on day 1. RESULTS: A total of 29 patients with metastatic biliary tract cancer received GEMFUFOL regimen as the first- line treatment. The mean follow-up was 22.1 months (95%CI, 12.5-31.8). One patient (3.4%) achieved complete response, 5 (17.2%) had partial response, and 4 (13.8%) had stable disease. The median progression-free survival was 3.3 months (95%CI, 2.9-3.7), and the median overall survival was 8.8 months (95%CI, 3.5-14). The 1-year and 2-year survival rates were 58.6% and 30%, respectively. Grade 3 and 4 toxicity included neutropenia in 4 patients (13.7%), thrombocytopenia in 2 (6.8%), anemia in 2 (6.8%), and alopecia in 1 (3.4%). Two patients (6.8%) developed febrile neutropenia. A dose reduction was achieved in 8 patients (27.6%) while 5 patients had extended-interval dosage (17.2%) for toxicity. CONCLUSIONS: The GEMFUFOL chemotherapy regimen was generally efficacious and tolerable as a first-line treatment of metastatic biliary tract cancer.

Relationship between epidermal growth factor receptor gene mutations and clinicopathological features in patients with non-small cell lung cancer in western Turkey.

BACKGROUND: To investigate epidermal growth factor receptor (EGFR) gene mutations in patients with non- small cell lung cancer (NSCLC) and to analyze any relationship with clinicopathological features and prognosis. MATERIALS AND METHODS: EGFR gene exons 18-21 in 48 specimens of paraffin-embedded tumor tissue from NSCLC patients were amplified by PCR, followed by direct sequencing and analysis of links to clinicopathological features and prognosis. RESULTS: EGFR mutations were detected in 18 of 48 (42.6%) patients with NSCLC. There were 9 cases of mutations in exon 20, 7 in exon 19 and 2 in exon 21. Mutations were more frequently observed in women (5/7 pts, 71.4%) than in men (13/41 pts, 31.7%) (p=0.086) and in non-smokers (5/5 pts, 100%) than smokers (13/43 pts, 30.2%). There was negative correlation of EGFR mutations with smoking status (p=0.005). EGFR mutations were more frequently observed with adenocarcinoma histology (13/32 pts, 40.6%) than in other types (5/16 pts, 31.3%) (p=0.527). The patients with EGFR mutations had better survival than those with wild- type EGFR (p=0.08). There was no association of EGFR mutations with metastatic spread. CONCLUSIONS: EGFR mutations in NSCLC were here demonstrated more frequently in females, non-smokers and adenocarcinoma histology in the western region of Turkey. Patients with EGFR mutations have a better prognosis.
