Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

[EX Q]: Poor condition at operation determined by the physiologic POSSUM score is related to postoperative mortality and morbidity of colorectal cancer surgery. This study was designed to analyze the relationship between condition of patients with colorectal cancer at operation and long-term overall survival.', 'A total of 542 patients survived a radical resection for Stages I, II, or III colorectal cancer. Physiologic POSSUM score at surgery, exclusive of age, was calculated for all patients. Mean physiologic POSSUM score was used as cutoff point to determine low-risk and high-risk group patients. A Cox proportional hazard analysis was performed to study the effect of low-risk and high-risk group on overall survival and to identify independent risk factors.', 'Five-year overall survival was significantly higher in low-risk group patients than in high-risk group patients (low-risk group 66.6 percent vs. high-risk group 48.5 percent; P < 0.001). Differences in overall survival also were found when patients in Stages I, II, and III were analyzed separately. Risk factors for overall survival were advanced stage of disease, poor tumor differentiation, mucinous adenocarcinoma, older than age 70 years, and poor condition of the patient at time of operation.

[EX Q]: To investigate the effect of targeted antiosteosarcoma methotrexate-bisphosphonate conjugate on growth inhibition and apoptosis in human osteosarcoma MG-63 cells.', 'MG-63 cells were treated with various concentrations of methotrexate-bisphosphonate conjugate and apoptosis was monitored via an MTT assay, cell morphology, TUNEL assay and flow cytometry analysis.', 'The survival rate of MG-63 cells treated for 24 to 96 hours with 2000 mg/ml or more of methotrexate-bisphosphonate conjugate decreased significantly. Cells treated with conjugate showed typical apoptotic features using inverted phase contrast microscopy and fluorescence staining, and the majority of cells demonstrated a positive result in the TUNEL assay. Karyopyknosis and crescent aggregation of chromatin were observed in conjugate-treated cells by electron microscopy. Flow cytometry of MG-63 cells treated with methotrexate-bisphosphonate conjugate showed a time and dose-dependent increase in apoptosis (p < 0.05).

[EX Q]: Extranodal natural killer/T-cell lymphoma (NKTCL) is a clinically heterogeneous disease with a poor prognosis, requiring risk-stratified management in affected patients. Recently, tumor microenvironment including regulatory T cells (Tregs) has been implicated as a prognostic marker in certain types of lymphoma.', 'We collected 64 NKTCL cases and numerically quantified the amount of tumor-infiltrating FOXP3-positive Tregs by automated slide scanning and image analysis program after immunohistochemical staining using anti-FOXP3 antibody.', 'Patients were able to be classified into two end groups by their level of Tregs. Twenty-eight (44%) patients had Tregs <50/0.40 mm(2), while 36 (56%) had Tregs > or =50/0.40 mm(2) within the tumor. The decreased number of Tregs (<50/0.40 mm(2)) was more common in patients with poor performance status or in those presented in non-upper aerodigestive tract. However, the level of Tregs was not associated with other prognostic factors, including stage, lactate dehydrogenase level, International Prognostic Index, and NKTCL Prognostic Index. Importantly, patients with increased numbers of Tregs (> or =50/0.40 mm(2)) showed prolonged overall and progression-free survival (P = 0.0005 and P = 0.0079, respectively). The number of FOXP3-positive Tregs was an independent prognostic factor (P = 0.001) by multivariate analysis.
