Impact of systemic inflammatory markers in patients with ALK-positive non-small cell lung cancer treated with crizotinib.

OBJECTIVES: To evaluate the prognostic utility of inflammation-based prognostic scores in patients with ALK-positive metastatic or non-resectable non-small-cell lung cancer (NSCLC) treated with crizotinib. PATIENTS AND METHODS: A total of 82 patients with ALK-positive metastatic or non-resectable NSCLC who received ALK TKI crizotinib were included. Pre-treatment modified Glasgow prognostic score (mGPS), prognostic nutritional index (PNI), and systemic immune-inflammation index (SII) were calculated. Multivariable logistic regression and Cox proportional hazards models were used to assess the impact of pretreatment mGPS, PNI, and SII on overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). RESULTS: The ORR was 77.2%, while 1-year OS and PFS rates were 95.0% and 93.5%, respectively. The univariate analysis revealed significantly higher 1-year PFS (89.4 vs. 64.4%, p=0.043) and OS (92.0 vs. 83.3%, p=0.01) rates in patients with low (<934.7) vs. high (≥934.7) SII scores. Multivariate analysis revealed that PNI ≥0.09 was a significant determinant of poorer 1-year OS rates (hazard ratio [HR]: 2.46, 95% confidence interval [CI] 0.88-4.85, p=0.035). No significant difference was observed in survival rates according to gender, age, smoking status, prior lines of therapy, or mGPS scores, while higher mGPS scores (odds ratio [OR]: 0.1, 95%CI 0.16-1.04; p=0.009) and higher PNI scores (OR: 0.16, 95% CI 0.02-0.55; p=0.035) were associated with poorer ORR. CONCLUSION: Our findings indicate the prognostic significance of PNI and SII in terms of survival outcome and the impact of mGPS and PNI on treatment response in patients with ALK-positive NSCLC treated with crizotinib.

Pertuzumab, trastuzumab and taxane-based treatment for visceral organ metastatic, trastuzumab-naïve breast cancer: real-life practice outcomes.

PURPOSE: In this study, we aimed to describe the real-life practice outcomes of pertuzumab-trastuzumab-taxane (PTT) combination in visceral organ metastatic, trastuzumab-naive breast cancer (BC) patients. METHODS: This study was conducted by Turkish Oncology Group and included 317 patients' data from 36 centers. RESULTS: Median age was 51 (22-82). Median PFS was 28.5 months, while median OS was 40.3 months. Patients with brain metastases (n: 13, 4.1%) had worse PFS (16.8 m vs. 28.5 m; p = 0.002) and OS (26.7 m vs. 40.3 m; p = 0.009). Patients older than 65 years of age (n: 42, 13.2%) had significantly lower OS results (19.8 m vs. 40.3 m; p = 0.01). Two hundred sixty-eight patients (86.7%) received docetaxel while 37 patients (11.7%) received paclitaxel. PFS and OS were similar between taxane groups. In eight patients (2.5%), 5-40% ejection fraction decrement from baseline was detected without any clinical sign of heart failure. CONCLUSIONS: Our RLP trial included only visceral metastatic, trastuzumab-naïve BC patients including cases with brain involvement who received PTT combination in the first-line treatment. Regardless of negative prognostic characteristics, our results are in parallel with pivotal trial. Further strategies for brain metastasis should be developed to improve outcomes despite encouraging results with PTT treatment. Taxane selection can be personalized and endocrine maintenance may further improve outcomes after taxanes were discontinued. To our knowledge, this is the largest scale real-life clinical practice study of pertuzumab-trastuzumab-taxane therapy to date.

Comparison of second-line treatment outcomes between sensitive and refractory small cell lung cancer patients: a retrospective analysis

PURPOSE: Small cell lung cancer (SCLC) has a high relapse rate despite being very chemosensitive. The efficacy of second-line treatment is dismal. Our aim was to evaluate the outcome of second-line treatment. METHODS: We retrospectively assessed data of 120 SCLC patients who failed first-line treatment and received second-line treatment at three medical oncology centers. RESULTS: Median age of group was 58. 82 % had an ECOG PS of 0-1 at the time of relapse. 39 % were at limited stage (LS) at the time of diagnosis. Patients who progressed more than 3 months after first-line therapy were categorized as having platinum-sensitive disease (PSD) (64 %). The number of patients who received platin-based combination treatment was 33 (27 %). The median OS time starting from the initiation of second-line treatment was 7 months. Multivariate analysis identified PS (p = 0.006), extent of disease at diagnosis (0.014) and PSD (0.001) as the independent prognostic factors for survival. Subgroup analyses of the patients with PSD indicated platin rechallenge yields higher progression-free survival, overall survival and overall response rate. CONCLUSION: Patients with good ECOG PS,who have PSD or initially presenting with LS, have a good prognosis and in patients with PSD, platinum-based therapy would be more appropriate (AU)

Safety and tolerability of first-line bevacizumab in metastatic colorectal cancer.

PURPOSE: To determine the clinical features of bevacizumab-associated toxicities in metastatic colorectal cancer (MCRC) patients. METHODS: The medical records of 60 patients with MCRC who were treated with chemotherapy including bevacizumab in the first-line setting were retrospectively evaluated. RESULTS: Bevacizumab was administered along with irinotecan plus 5-fluorouracil7sol;leucovorin (5-FU/LV) to 44 patients, 57horbar;FU7sol;LV+oxaliplatin to 8 patients, capecitabine+oxaliplatin to 6 patients and 5-FU/LV to 2 patients. The total number of the cycles received was 381 (median 6, range 17horbar;13). The most common bevacizumab-related toxicity was grade 1-2 bleeding (28%) followed by hypertension (17%). Grade 1-2 proteinuria was seen in 8% of the patients (no grade 3-4 proteinuria). Arterial thromboembolic events (ATE) were not observed, however 3 patients (5%) had experienced grade 3-4 venous thromboembolic events. In 3 patients (5%) grade 1-2 wound complications were seen (delayed wound healing in the place of the venous access device in 2, and wound infection in 1). In addition, gastrointestinal perforation (GIP) was seen in 3 (5%) patients. Two of the patients were treated by surgical intervention and one patient died of sepsis. CONCLUSION: Bevacizumab is well tolerated when combined with various chemotherapy regimens. As bevacizumab is becoming widely used in the routine oncology practice, further studies which investigate the mechanism of bevacizumab-associated toxicities are warranted to develop effective management strategies for these adverse events.

ERCC1 is not expressed in hepatocellular cancer: A turkish oncology group, gastrointestinal oncology subgroup study.

PURPOSE: hepatocellular cancer (HCC) is a common malignancy with a high mortality rate. Existence of excisional repair cross complementation1 (ERCC1) is implicated in resistance to cisplatin treatment. Expression of ERCC1 in HCC is not known. In this study we aimed to find out whether a subset of HCC patients can be identified to benefit from cisplatin. METHODS: sixty-one patients with HCC who had enough tissue to do immunohistochemistry were identified in 3 institutions. Immunohistochemical staining was performed manually using the standard streptavidin-biotin-peroxidase method. Monoclonal anti-ERCC 1 (D-10) antibody from Santa Cruz Biotechnology (Santa Cruz, CA) was used. RESULTS: only one out of 61 patients (1.6%) had ERCC1 expression. CONCLUSION: although around 10% of HCC patients respond to cisplatin, this is unlikely to be due to ERCC1 negativity. Pathways other than ERCC1 should be searched to find ways to help these patients' treatment strategies.

Anxiety disorder in patients with non-specific chest pain in the emergency setting.

OBJECTIVES: Many patients who have been discharged from the emergency department (ED) with a diagnosis of "non-specific chest pain" (NSCP) have anxiety disorder (AD), a commonly missed entity in acute care. The objective of this study was to delineate characteristic properties that could enhance recognition of AD in ED patients admitted with NSCP. METHODS: All patients between 18 and 65 years of age diagnosed with NSCP were enrolled. The Hospital Anxiety and Depression Scale (HADS) anxiety subscale was used as a screening test for AD. The patients with high HADS scores (> or = 10) were evaluated by a psychiatrist for AD. RESULTS: In total, 157 patients were enrolled in the study. HADS scores were found to be "high" (> or = 10) in 49 patients (31.2%). Patients with high HADS scores had a higher frequency of associated symptoms (p = 0.004). Dizziness or lightheadedness, chills or hot flushes, and fear of dying were found to have been reported more frequently by patients with high anxiety scores. Of the group with high score, 33 patients (67.3%) were interviewed by a psychiatrist, and 23 (69.7%) of these patients were diagnosed with AD. Associated symptoms were described by 21 patients with AD (91.3%). Of those with AD, 18 (78.3%) had been previously admitted to the ED with chest pain. Atypical chest pain was described by 21 patients (91.3%). CONCLUSIONS: Physicians should always consider AD in patients presenting to the ED with chest pain after ruling out organic aetiology. Patients' definition of atypical pain, recurrent admissions to ED, and presence of associated symptoms such as dizziness, chills or hot flushes, and fear of dying could aid in considering AD.
