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]: To determine the frequency and clinical significance of epidermal growth factor receptor (EGFR) mutations in patients with potentially curable stage III non-small-cell lung cancer (NSCLC) who are eligible for definitive chemoradiotherapy (CRT).', 'Between January 2001 and December 2010, we analyzed the EGFR mutational status in consecutive NSCLC patients who were treated by CRT. The response rate, relapse-free survival, 2-year relapse-free rate, initial relapse sites, and overall survival of the patients were investigated.', 'A total of 528 patients received CRT at our hospital during the study period. Of these, 274 were diagnosed as having nonsquamous NSCLC. Sufficient specimens for mutational analyses could be obtained from 198 of these patients. The proportion of patients with EGFR activating mutations was 17%. In addition to the well-known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild-type EGFR. Patients with EGFR mutations showed similar response rate, relapse-free survival, and 2-year relapse-free rates as compared to patients with wild-type EGFR. Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). Patients with EGFR mutations showed longer local control (adjusted hazard ratio 0.49; P=.043). After disease progression, a majority of the patients with EGFR mutations received EGFR tyrosine kinase inhibitors (62%), and these patients showed longer postprogression survival than those with wild-type EGFR.

[EX Q]: Stigma has been suggested as a possible contributor to the high rates of treatment attrition in substance-dependent individuals, but no published empirical studies have examined this association.', 'The present paper assessed the relationship between baseline stigma variables and length of treatment stay in a sample of patients in a residential addictions treatment unit.', 'The relationship between baseline stigma variables (self-stigma, enacted stigma, and shame) and length of stay for participants (n=103) in a residential addictions treatment unit was examined.', 'Higher self-stigma predicted longer stay in residential addictions treatment, even after controlling for age, marital status, race, overall mental health, social support, enacted stigma, and internalized shame. However, other stigma variables (i.e. internalized shame, stigma-related rejection) did not reliably predict length of treatment stay.

[EX Q]: Hydrocelectomy and spermatocelectomy are routine scrotal surgeries. A\xa0significant number of the surgical specimens are sent for pathology analysis. However, to our knowledge no study has been done to examine outcomes and necessity, which results in significant potentially unnecessary costs to the patient and the health care system. We evaluated outcomes and surgical pathology analysis of hydroceles and spermatoceles.', 'We performed a retrospective, single institution chart review of all patients who underwent initial surgery for hydrocele or spermatocele between January 2000 and August 2013. We determined the number of cases in which a surgical specimen was sent for pathology examination. The cost for each specimen was estimated at the department of pathology.', 'A total of 264 routine scrotal cases were performed during the 14-year period. Surgical specimens were sent for pathology analysis in 102 hydrocelectomy cases (51%) and in 57 spermatocelectomy cases (90%). No pathology specimen showed any indication of malignancy. The estimated direct total cost of\xa0pathology analysis was $49,449 in this cohort.
