The aim of this retrospective, multicenter study was to evaluate clinicopathological characteristics, prognostic factors and treatment outcomes of teenage and adult patients with high-grade osteosarcoma. A total of 240 osteosarcoma patients who were diagnosed and treated from March 1995 to September 2011 were analyzed. Median age was 20 years (range 13-74 years), and 153 patients (63.8%) were male. Primary tumor localization was extremity in 204 patients (85.4 %), trunk in 21 patients (8.8%) and head and neck region in 14 patients (5.9%). According to American Joint Committee on Cancer staging system, 186 patients (77.5%) were stage II, 3 (1.3%) were stage III and 48 (20.0%) were stage IV. Median overall survival (OS) was 55 months (95 % CI 36.8-73.1 months). OS after 2, 5 and 10 years were 67, 49 and 42%, respectively. Univariable analysis for OS showed that male gender (p = 0.032), high baseline lactate dehydrogenase (LDH) level (p < 0.001), high baseline serum alkaline phosphatase level (p = 0.002), telangiectatic subtype (p = 0.023), presence of metastasis at diagnosis (p < 0.001), presence of tumor positive margins after primary surgery (p = 0.015), poor pathological response to preoperative chemotherapy (p = 0.006) and presence of recurrent disease during follow-up period (p < 0.001) were significantly associated with poor survival. Patients who received postoperative methotrexate plus doxorubicin plus cisplatin (M + A + P) combination regimen (p = 0.019), underwent surgery for recurrent disease (p < 0.001) and received chemotherapy for recurrent disease (p < 0.001) had longer OS. In multivariable analysis for OS, only high LDH level (p = 0.002) and the presence of metastasis at diagnosis (p = 0.011) were associated with poor OS, whereas the patients who received chemotherapy for recurrent disease had a longer OS (p = 0.009).

In patients with localized abdominal pain without other symptoms, diagnosis of EA should be considered. Recognizing the US and CT features of EA may allow an accurate diagnosis and avoid unnecessary surgery.

<b><i>Background:</i></b> Colorectal cancer (CRC) is a rare disease amongst children and adolescents. Previous studies have reported a number of differences between children/adolescents, young adults, and adult patients with CRC. However, none of these studies compared these age groups according to their clinicopathologic and prognostic characteristics. In the current study, we compare these three age groups. <b><i>Methods:</i></b>A total of 173 (1.1% of 15,654 patients) young CRC patients (≤25 years) were included in the study. As a control group, 237 adult CRC patients (&#x3e;25 years) were also included. Patients were divided into three age groups: child/adolescent (10–19 years), young adult (20–25 years), and adult (&#x3e;25 years). <b><i>Results:</i></b> Statistical differences amongst the three groups in terms of gender (<i>p</i> = 0.446), family history (<i>p</i> = 0.578), symptoms of presentation (<i>p</i> = 0.306), and interval between initiation of symptoms and diagnosis (<i>p</i> = 0.710) could not be demonstrated. Whilst abdominal pain (<i>p</i> &#x3c; 0.001) and vomiting (<i>p</i> = 0.002) were less common in young adults than in other groups, rectal bleeding and changes in bowel habits were relatively less common in adolescents than in other groups. Rectal localisation (<i>p</i> = 0.035), mucinous adenocarcinoma (<i>p</i> &#x3c; 0.001), and a poorly differentiated histologic subtype (<i>p</i> &#x3c; 0.001) were less common in the adult group than in other groups. The percentage of patients with metastasis and sites of metastasis (e.g., peritoneum and lung) differed between groups. The median overall survival was 32.6 months in the adolescent group, 57.8 months in the young adult group and was not reached in the adult group (<i>p</i> = 0.022). The median event-free survival of the adolescent, young adult, and adult groups was 29.0, 29.9, and 61.6 months, respectively (<i>p</i> = 0.003). <b><i>Conclusions:</i></b> CRC patients of different age groups present different clinicopathologic and prognostic characteristics. Clinicians should be aware of and manage the disease according to these differences.

Introduction: The aim of the present study was to assess the predictive value of the age, creatinine, ejection fraction score for in-hospital mortality in patients with cardiogenic shock secondary to ST-elevation myocardial infarction. Material and methods: This single-center, retrospective study was based on a comprehensive analysis of the hospital records of 318 consecutive cardiogenic shock patients. The age, creatinine, ejection fraction score was calculated for each patient using the equation of age/ejection fraction +1 if creatinine level is >2 mg/dl. The study population was stratified into tertiles: T1, T2, and T3, based on the age, creatinine, ejection fraction score. The primary endpoint of the study was the incidence of in-hospital mortality. Results: The incidence of in-hospital mortality was significantly greater in patients with a high age, creatinine, ejection fraction score (T3 group) compared with the intermediate (T2 group) or the low score group (T1 group) [86.8% (n = 92 patients) vs. 57.5% (n = 61 patients) vs. 34.9% (n = 37 patients), respectively; P < 0.05 for each]. In multivariable models, after adjusting for all covariables, the risk of in-hospital mortality was 3.21 (95% confidence interval: 2.29–4.58) for patients allocated to the T3 group. The optimal cutoff for the age, creatinine, ejection fraction score for in-hospital mortality was 2.24, with a sensitivity of 74% and a specificity of 77%. Conclusion: To the best of our knowledge, this is the first study that has demonstrated a prognostic value of the age, creatinine, ejection fraction score in patients with ST-elevation myocardial infarction-related cardiogenic shock.
