•We show in a sample of 72 cancer patients that watercolor painting (PATP) as a form of art therapy improves quality of life and depression.•Moreover, PATP is feasible in patients during their ...chemotherapy sessions.•We advise art therapy in general and PATP in particular for cancer patients while on active treatment.
There is limited data on the role of art therapy used in cancer patients. We wanted to test the effect of painting art therapy provided by a dedicated professional painting artist on quality of life and anxiety and depression levels in patients having chemotherapy.
Cancer patients having chemotherapy in the day unit of a medical oncology department of a university hospital were offered to take part in a painting art therapy program (PATP). This program consisted of a professional painting artist facilitating and helping patients to perform painting during their chemotherapy sessions while they were in the day unit, as well as supplying them painting material for home practice. The changes in quality of life domains of EORTC-QLQ-C30 questionnaire and in Hospital Anxiety and Depression Scores (HADS) were assessed before and after the PATP. These results were contrasted with a reference group of cancer patients on chemotherapy but not taking part in the PATP. In order to adjust for multiple comparisons of quality of life parameters between patient groups, we utilized the Bonferroni correction.
A total of 48 patients, of which 26 patients did and 22 did not have prior exposure to PATP, were enrolled in the PATP. A control group of 24 patients who did not have any PATP activity during the study period also took part in the study. With PATP, there was significant improvement in global quality of life (F=7.87, P=0.001), and depression scores (F=7.80, P=0.001).
To our knowledge, this is the largest comparative PATP experience in cancer patients on chemotherapy and show that PATP is feasible in the clinics. Our results confirm that art therapy in the form of painting improves quality of life and depression in cancer patients having chemotherapy. This effect was more pronounced in patients without any previous experience of PATP.
Purpose
There is clinical need to predict risk of febrile neutropenia before a specific cycle of chemotherapy in cancer patients.
Methods
Data on 3882 chemotherapy cycles in 1089 consecutive patients ...with lung, breast, and colon cancer from four teaching hospitals were used to construct a predictive model for febrile neutropenia. A final nomogram derived from the multivariate predictive model was prospectively confirmed in a second cohort of 960 consecutive cases and 1444 cycles.
Results
The following factors were used to construct the nomogram: previous history of febrile neutropenia, pre-cycle lymphocyte count, type of cancer, cycle of current chemotherapy, and patient age. The predictive model had a concordance index of 0.95 (95 % confidence interval (CI) = 0.91–0.99) in the derivation cohort and 0.85 (95 % CI = 0.80–0.91) in the external validation cohort. A threshold of 15 % for the risk of febrile neutropenia in the derivation cohort was associated with a sensitivity of 0.76 and specificity of 0.98. These figures were 1.00 and 0.49 in the validation cohort if a risk threshold of 50 % was chosen.
Conclusions
This nomogram is helpful in the prediction of febrile neutropenia after chemotherapy in patients with lung, breast, and colon cancer. Usage of this nomogram may help decrease the morbidity and mortality associated with febrile neutropenia and deserves further validation.
Background Identification of biomarkers that can be used for the prognostic evaluation of NSCLC patients is important. The aim of this study was to evaluate the potential prognostic value of XRCC1 , ...ERCC1 , ERCC2 , and TP53 SNPs in completely resected NSCLC patients. Methods One hundred and thirty patients, who had been surgically treated for NSCLC between 2000 and 2012, were included in this study. Analysis of SNPs from peripheral blood cells was performed by PCR. XRCC1 Arg399Gln, ERCC1 Asn118Asn, ERCC2 Lys751Gln, and TP53 Arg72Pro polymorphisms were evaluated in conjunction with clinical and pathological parameters and survival. Kaplan–Meier method and Cox regression analysis were used. Findings In the univariate analysis for disease-free survival (DFS), postoperative stage (hazard ratio HR 0.50, 95% confidence interval CI 0.26–0.96; p = 0.03), ERCC2 genotype (HR 2.47, 95% CI 1.28–4.78; p = 0.007), and PET-CT staging (HR 0.27, 95%CI 0.14–0.52; p < 0.001) were significant parameters. Adjuvant chemotherapy, age, and the other SNPs were not significant. In the multivariate analysis, post-operative stage (HR 0.40, 95% CI 0.20–0.81; p = 0.01), ERCC2 genotype (HR 2.66, 95% CI 1.35–5.27; p = 0.005), PET-CT staging (HR 0.24, 95% CI 0.12–0.47; p < 0.001) retained their significance. Median DFS was 56.5 months (95% CI 24.6–88.4) for the ERCC2 mutant (TT) and heterozygote (GT) genotypes, and 28.3 months (95% CI 20.8–35.8) for the ERCC2 normal (GG) genotype (p = 0.005). Interpretation In addition to stage and PET-CT staging, ERCC2 genotype independently predicted DFS in resected NSCLC patients. Future prospective studies are needed for the further evaluation of potential prognostic SNPs in resected NSCLC.
A number of studies have been carried out, showing that the risk for breast carcinoma is decreased in those using non-steroidal anti-inflammatory drugs (NSAIDs). Increased cyclooxygenase-2 (COX-2) ...level is considered as a factor indicating poor prognosis and responsible for angiogenesis, increased cellular proliferation, apoptotic defect and aromatase enzyme induction. For this reason the level of COX-2 might have a prognostic and predictive value in breast cancer as well. This question has become the basis of the present study.
Eighty-eight female patients with early stage breast cancer being under adjuvant anthracycline based chemotherapy were prospectively recruited. The patient age, body weight, menopausal status, tumor size and grade as well as axillary lymph node involvement were recorded. Routine pathological examination was performed, and COX-2, CerbB2 (HER2), estrogen (ER) and progesterone receptors (PR) levels in breast cancer tissue were determined immunohistochemically.
Multivariate analysis confirmed the independent predictive value of both menopausal status and ER expression for overall survival (OS) (p=0.009, HR=1.92, and p=0.014, HR=0.20, respectively). A negative correlation was observed between COX-2 levels and the levels of ER and PR (p=0.006, R= -0.303, and p=0.004, R=-0.312, respectively) whereas no significant correlation was observed concerning CerbB2. No statistically significant correlation was determined between COX-2 levels and the disease-free (DFS) and OS rates.
Further studies investigating the role of COX- 2 levels in breast cancer progression are needed.
We tested whether zoledronic acid, a biphosphonate with proposed apoptotic activity, augmented the cytotoxicity of cisplatin and/or gemcitabine in A549 lung cancer cell line. This cell line was ...subjected to different concentrations of the above chemotherapeutic agents and zoledronic acid. Cytotoxicity was assessed by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrasodium bromide) assay. Particularly, zoledronic acid in 100 micromolar (μM) concentration augmented the cytotoxicity by cisplatin 1
μg/ml from 25% to 70% (
Z
=
3.22,
P
=
0.0072). A significant portion of cells underwent apoptosis with or without zoledronic acid, but more so with the combination treatment as assessed by an Annexin V-FITC apoptosis detection kit. However, 100
μM zoledronic acid showed 50% cytotoxicity on its own, but failed to improve cytotoxicity by Gemcitabine. Thus, we show for the first time in a lung cancer cell line that zoledronic acid bears cytotoxic potential on its own and in conjunction with cisplatin. The clinical potential of this finding should be further studied.
We aimed to analyze the predictors of outcome in metastatic germ cell cancer (MGCC) patients treated with High-dose Chemotherapy (HDC) and stem cell rescue.
Various prognostic factors have been ...suggested in the treatment of metastatic germ cell cancer. However, there is no comprehensive evaluation of independent prognostic factors for the efficacy of HDC in published patient cohorts.
Thirty-two published patient cohorts with MGCC (encompassing 2176 patients; 510 patients treated upfront and 1666 at relapse) were identified from PUBMED and Cochrane Registry of Clinical Trials. Weighted Regression Analyses of these trials were conducted to define prognosticators.
Independent correlates of overall survival (OAS) when all trials were considered were line of chemotherapy index, an indicator of line of HDC utilization (1st line: 71% vs 2nd or higher line: 40%, p < 0.001), and number of HDC cycles administered (1 cycle: 43%, 1 to 2 cycles: 43%, 2 or more cycles: 64%, p = 0.021). In cohorts having HDC for relapsed disease, lower line of chemotherapy index again (p = 0.004), and higher median age (p = 0.023) were independently associated with better OAS. In trials utilizing upfront HDC, higher number of chemotherapeutics in the HDC regimen was marginally linked with improved OAS (p = 0.047).
The efficacy of various forms of HDC in MGCC patients with diverse prognostic factors may vary both as an initial or salvage therapy. Clinicians need to be aware of these factors for optimal patient selection for HDC in MGCC (Tab. 3, Fig. 2, Ref. 54).
OBJECTIVE: We present our data comparing retrospectively the efficacy of abiraterone and cabazitaxel in patients who progress after docetaxel treatment. PATIENTS AND METHODS: The study included 56 ...patients diagnosed with hormone-refractory metastatic prostate cancer who were previously treated with abiraterone therapy at four oncology centers in Turkey. RESULTS: With abiraterone, the patients had a median progression-free survival (PFS) of 5.9 months (95% confidence interval (CI) for hazard ratio (HR) (4.4-7.4)) and an overall survival of 13.4 months (95% CI for HR (5.5-21.3)). When we compared the disease-free survival (DFS) of reference patients treated with cabazitaxel as a second-line treatment with those receiving second-line abiraterone therapy, there was no significant difference. (PFS = 5.9 months with cabazitaxel vs. 6.7 months with abiraterone, P = 0.213). CONCLUSION: This study has shown that in our experience abiraterone acetate is an effective agent in metastatic castration-resistant prostate cancer (mCRPC) regardless of the line of treatment.

CONTEXT: Introduction of trastuzumab, a recombinant monoclonal antibody against the extracellular domain of HER-2, is a cornerstone in the treatment of HER-2+ breast carcinoma. However, many cancers ...that have an initial response to trastuzumab will progress some time later. After progression on trastuzumab-based first-line treatment, there are several options. Although TDM-1 (Trastuzumab emtansine) has prolonged progression-free survival (PFS) and overall survival in patients previously treated with trastuzumab and taxane, it is still not available in Turkey. Patients may be switched to lapatinib (an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2), or they may re-challenge with trastuzumab. There is no clear definition of the patients who should be switched to lapatinib. AIM: In this study, we investigated the factors predicting the efficacy of lapatinib. SUBJECTS AND METHODS: Totally, 94 patients treated with lapatinib for metastatic breast carcinoma was included in our study. Retrospective data including pathology, treatments and treatment results, metastatic sites, and laboratory tests were collected. RESULTS: Progression-free survival was 9.1 months. Histologic subtypes other than invasive ductal carcinoma and liver metastasis were inversely related with PFS. Overall survival was 22.1 months, and patients with histologic subtypes other than invasive ductal carcinoma and who progress with brain metastasis had a worse prognosis. CONCLUSION: Clinicians should give attention to histologic subtype and metastatic sites when choosing patients for lapatinib treatment.
