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.

Q: Although trastuzumab improves the outcome of patients with human epidermal growth factor receptor\xa02 (HER2)-overexpressing gastric or gastroesophageal junction adenocarcinoma (collectively referred to as "gastroesophageal adenocarcinoma"; GEA), no clinical response is observed in a substantial population of patients. A predictive biomarker of trastuzumab response is required. The aim of this study was to evaluate whether the hyperactivation of the downstream phosphatidylinositol 3-kinase pathway, due to phosphatase and tensin homolog (PTEN) loss or PIK3CA mutations, could provide trastuzumab resistance in GEA.', 'Expression of HER2 and PTEN, and PIK3CA gene mutations were screened in 264 surgically resected GEA specimens. The effects of PTEN knockdown on the response to trastuzumab on cell viability, HER2 downstream signaling, apoptosis, and cell cycle were evaluated in HER2-overexpressing NCI-N87 gastric adenocarcinoma and OE19 esophageal adenocarcinoma cell lines. Inhibition of xenograft tumor growth by trastuzumab was investigated in OE19 cells with or without PTEN knockdown. The PTEN expression and objective response were analyzed in 23 GEA patients who received trastuzumab-based therapy.', 'PTEN loss was identified in 34.5\xa0% of HER2-overexpressing GEA patients, whereas PIK3CA mutations were rare (5.6\xa0%). Trastuzumab-mediated growth suppression, apoptosis, and G

Q: Limited knowledge exists about the value of tumor size in surgically treated cervical cancer (CX) using a tumor size of 2 cm as cut-off value.', 'A total of 366 cases of CX FIGO stage IB who received upfront surgery were evaluated regarding tumor size, the prediction of pelvic lymph node involvement, and recurrence-free and overall survival during a median follow-up time of 94 months. Tumors ≤2.0 cm were defined as small, tumors 2.1-4.0 cm as medium sized and those larger than 4 cm as bulky disease.', 'Small tumors were seen in 28.7%, medium sized in 52.5% and bulky tumors in 18.9%. There was a significant higher frequency of pelvic lymph node involvement with increasing tumor size (13.3% vs. 23.4% vs. 43.5%, respectively; p<0.001) and an increase of recurrent disease (6.7% vs. 18.8% vs. 29.4%, respectively; p<0.001). The 5-year overall survival rate was significantly reduced with increasing tumor size (94.0% vs. 85.1% vs. 69.9%, respectively; p<0.001). Pelvic lymph node involvement and maximal tumor size were independent prognostic factors for both recurrence-free and overall survival in multivariate analysis.

Q: Limited data are available regarding the impact of caloric restriction (CR) in combination with resistance training (RT) on the metabolic profile of postmenopausal women.', 'The objective of the study was to determine whether RT adds to CR in improving body composition and the metabolic profile.', 'This was a 6-month, randomized, clinical trial.', 'Patients included 107 postmenopausal women (body mass index >27 kg/m(2)).', 'The intervention was a 6-month CR alone or in combination with a RT program.', 'Fat mass (FM), lean body mass (LBM), abdominal sc fat and visceral fat, fasting lipids, insulin sensitivity, resting blood pressure, and inflammation markers were measured.', 'Both groups were similar at baseline and significantly decreased body weight, body mass index, FM, percent FM, abdominal sc fat, and visceral fat after the study (P < 0.001), with greater losses of percent FM and trunk FM in the CR + RT group (P < 0.05). LMB significantly decreased in the CR (-0.9 +/- 2.4 kg) and the CR+RT (-0.4 +/- 2.2 kg) groups (P < 0.005), with no difference between them. Both groups significantly improved plasma triglycerides, fasting insulin level, glucose disposal, and markers of the inflammation profile after weight loss (P < 0.05), with no difference between groups. No improvements were observed for the other variables of interest in both groups.
