Oncology staff: burnout, job satisfaction and coping with stress

The oncology staff is at high risk for developing psychological disorders and burnout. In this study, we aimed to evaluate their burnout levels, job satisfaction, psychological statement and ways of coping with stress and the relationship between these variables and their sociodemographic and occupational characteristics.

Clinical and Pathological Features of Breast Cancer Associated with the Pathological Complete Response to Anthracycline-Based Neoadjuvant Chemotherapy

Objective: Patients with breast cancer with a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) have a better prognosis than patients with residual disease. The aim of the current study was to identify predictors of pCR. Methods: This retrospective study included 388 patients treated with anthracycline-based NAC. Clinicopathological parameters were compared between the patients with and without pCR in breast and axilla. Results: Treatment consisted of FAC/FEC in 230 patients (59%), TAC in 39 (10%) patients and AC followed by docetaxel in 119 (31%). In all, 36 (9.3%) patients had pCR. In univariate analysis, age, tumor size, lymph node involvement, tumor grade (p = 0.077, n = 265), ER and HER-2 status (n = 213), lymphovascular invasion (LVI), type of chemotherapy and taxane-containing chemotherapy were associated with pCR. In multivariate analysis, ER negativity (p = 0.003), the absence of LVI (p = 0.009) and taxane-containing NAC (p = 0.026) were found to be significant indicators of pCR. Median follow-up time was 69 months. Progression-free survival was significantly improved in patients achieving pCR (p = 0.001). Conclusions: pCR is associated with a better outcome regardless of clinical and pathological parameters in breast cancer patients who receive NAC. The probability of pCR was higher in ER-negative, LVI-negative tumors and in patients treated with sequential taxane-containing chemotherapy.

Concomitant etoposide and cisplatin provided improved survival compared with docetaxel and cisplatin in patients with locally advanced non-small cell lung cancer treated with chemoradiotherapy.

AbstractPresently, there is no consensus regarding which chemotherapy regimen is best to administer with radiotherapy in patients with locally advanced non-small-cell lung cancer (LA-NSCLC). Herein, our aim was to compare the outcome of patients treated with either etoposide–cisplatin (EP) or docetaxel–cisplatin (DP) in this curative setting.Patients treated with either EP or DP and concurrent radiotherapy from 2004 to2012 were identified and their detailed medical records and follow-up information were obtained for analysis in this retrospective study. Survival rates were compared using Cox proportional hazards regression models with adjustments for confounding parameters provided by propensity score methods.A total of 105 patients were treated with concurrent chemoradiotherapy for LA-NSCLC (stage IIB-IIIA-IIIB). The median ages were 54 years (range, 32–70 years) and 55 years (range, 37–73 years) in the EP (n = 50) and DP (n = 55) groups, respectively. The median follow-up time was 27 months (range, 1–132 months) in the EP group and 19 months (range, 1–96 months) in DP group. There was no significant difference in baseline clinicopathologic features including age, sex, performance status, histologic subtype, and clinical TNM stages between groups. In the univariate analysis, the median overall survival of patients treated with EP was higher than that of patients treated with DP (41 vs. 20 months, P = 0.003). Multivariate analysis further revealed a survival advantage with EP compared with DP (hazard ratio [HR], 0.46; 95% confidence interval: 0.25–0.83; P = 0.009). The toxicity profile of the 2treatment groups was similar except that pulmonary toxicity was higher in the DP group (grade 3–4: 0% vs. 6%, P = 0.024).Concurrent chemoradiotherapy with EP may provide more favorable outcomes than DP and with an acceptable safety profile.

Conventionally Fractionationed Volumetric Arc Therapy versus Hypofractionated Stereotactic Body Radiotherapy: Quality of Life, Side Effects, and Prostate-Specific Antigen Kinetics in Localized Prostate Cancer

OBJECTIVES To compare conventionally fractionationed volumetric arc therapy (VMAT) and hypofractionated stereotactic body radiotherapy (SBRT) modalities in terms of prostate-specific antigen (PSA) kinetics, toxicity, and quality of life (QOL) in patients with localized prostate cancer. METHODS Patients received radical radiotherapy as either 33.5 Gy/5 fr for SBRT or 75.6 Gy/35 fr for VMAT. International Prostate Symptom Score (IPSS) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Prostate Cancer Module (QLQ-PR25) forms were used to assess QOL. RESULTS Of the 48 patients (28 in SBRT and 20 in VMAT) included in the study, 40 (20 in SBRT and 20 in VMAT) were evaluated for QOL status. PSA control rate was 100% and PSA nadir value was 0.5 ng/dl in both arms during the median follow-up period of 23 months. The magnitude of PSA bounce was higher in the SBRT arm than in the VMAT arm (P = 0.01). The PSA decline rate in the VMAT arm was higher than in the SBRT arm (P = 0.028). Three (10.7%) patients treated with SBRT who had a history of transurethral resection of the prostate (TURP) experienced grade 3 urinary toxicity. No significant difference was observed concerning sexual activity and sexual functioning scores, whereas scores at 10.5 and 13.5 months were decreased in both arms. The SBRT and VMAT arms had similar urinary incontinence, bowel symptoms, and IPSS obstruction scores. The magnitude of increase in IPSS scores at treatment completion was higher in the VMAT arm than in the SBRT arm (P = 0.046). The decrease in hormonal symptom scores at 4.5, 10.5, and 13.5 months was higher in the VMAT arm than in the SBRT arm (P = 0.007, 0.027, and 0.021, respectively). CONCLUSIONS Both treatment modalities had similar effectiveness and provided acceptable outcomes in terms of toxicity and QOL. Grade 3 urinary toxicities might be eliminated with careful patient selection for SBRT.

Effect of the childhood trauma on the adjustment to cancer in the patients with breast cancer

BackgroundEarly identification of patients coping poorly is important for compliance with treatment and control of distress. This study aims to investigate the effect of the childhood trauma experience on the type of reaction and adjustment that the person exhibits to the cancer among the patients with breast cancer.MethodsThis cross-sectional study enrolled 310 patients with breast cancer. The effect of the childhood trauma and the psychological condition on the adjustment to cancer was investigated by assessing the adjustment to cancer, the experiences of childhood trauma and psychological status of the subjects using mental adjustment to cancer scale (MAC), childhood trauma questionnaire (CTQ28), Beck Depression Inventory (BDI) and Beck anxiety inventory (BAI).ResultsMajority of the subjects (77.4%) showed positive adjustment to cancer. Fighting spirit (63.9%) was the most commonly seen mechanism of adjustment to cancer. Of the subjects, 54.5% suffered at least one of the childhood trauma types. Among the patients, 47.1% had depression and 58.4% had anxiety. In the multivariate logistic regression analysis, emotional neglect and depression, respectively, have an effect on both positive and negative adjustment to cancer.ConclusionsOur study demonstrated that childhood trauma, especially emotional neglect, affects coping and adjustment among the patients with breast cancer. It is necessary to determine the childhood experiences to ensure the development of psychosocial interventions that will increase the adjustment and quality of life after the diagnosis of the cancer.

Assessment of Anxiety and Depression Status in Turkish Cutaneous Melanoma Patients

Background: Even though anxiety and depression are two mood disorders encountered commonly in cancer patients only few trials have been carried out so far in melanoma patients. The aim of the study was to determine the clinical prevalence of these disorders in Turkish cutaneous melanoma patients and to clarify possible clinicopathological factors influencing them. Material and methods: A total of 100 consecutive outpatient melanoma patients were enrolled and asked to complete the Hospital Anxiety and Depression Scale (HADS) questionnaire immediately after scheduled visits. Results: A total of 24 participants had clinical anxiety and 8 were diagnosed with borderline anxiety. Fifteen were diagnosed with clinical depression and 20 with borderline depression. Prior to melanoma diagnosis the majority of the patients, 93 and 86, were assessed as normal in terms of their anxiety and depression status, respectively (p<0.001). A statistically significant correlation was found between anxiety and depression scores (p<0.001). The patients with advanced disease were significantly more anxious and depressive than those with early stage disease. None of the other socio-demographic parameters was found to be correlated with anxiety and depression status. Conclusions: Because a large group of Turkish melanoma patients, nearly one third of the cohort, was found to be suffering from relevant anxiety and depression, it is of uttermost importance that psychological support and pharmacological intervention for these patients be commenced as soon as possible.

Circulating serum levels of angiopoietin-1 and angiopoietin-2 in nasopharynx and larynx carcinoma patients.

We aimed to determine the serum levels of angiogenic factors, namely angiopoietins, in nasopharyngeal and laryngeal carcinoma patients. We also aimed to seek the relation of these molecules with tumor grade and their utility as diagnostic biomarkers. We evaluated angiopoietin 1 and 2 levels innasopharynx and larynx cancer patients before treatment. Angiopoietin 2 levels were significantly elevated in larynx carcinoma patients and tended to be elevated in nasopharynx cancer patients compared with healthy controls. However, angiopoietin 1 levels were similar in cancer patients and controls. Angiopoietin 1 levels were significantly higher in nasopharyngeal cancer patients with advanced stages compared to earlier stages. On the other hand, angiopoietin 2 levels were similar in advanced and earlier stage cancer patients.

The Prognostic Factors and Outcome of Adult Medulloblastoma: Where We Stand

We designed our study to analyze the prognostic factors and treatment outcomes of adult medulloblastoma patients who received postoperative craniospinal irradiation. Fourty-three patients who were treated due to medulloblastoma at Istanbul University, Institute of Oncology between 1990 and 2013 were retrospectively analyzed. All of the patients were older than 18 years, with a median age of 27 years (range, 18–51 years). In 40 (93%) patients, total resection of the tumor was achieved, and 3 (7%) patients had undergone a subtotal tumoral resection. Risk assessment revealed 7 high-risk and 36 standard-risk patients. All patients received postoperative craniospinal irradiation, delivering a median craniospinal dose of 36 Gy, with an additional boost to the posterior fossa up to 54 Gy. Fifteen patients received chemotherapy. The median follow-up was 62 months (range, 3–213 months). The 5-year, 10-year, overall, and disease-free survival rates were 63%, 51%, 66%, and 55%, respectively. Univariate analysis reve...
