In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: The caudal-type homeodomain transcriptional factor CDX2, a member of the caudal-related homeobox gene family, plays a crucial role in the regulation of cell proliferation and differentiation in the gut. Recent studies have reported that expression of CDX2 was an independent marker of outcome in patients with resected adenocarcinoma of ampulla of Vater, gastric cancer, and colon cancer. The clinicopathological significance of CDX2 expression has hitherto remained unclear in biliary tract carcinoma (BTC). The aim of this study was to determine whether CDX2 expression in BTC indicates clinical outcome.', 'The expression of CDX2 was investigated immunohistochemically in surgically resected specimens from 164 patients with BTC, including 74 intrahepatic cholangiocarcinomas, 49 extrahepatic cholangiocarcinomas, and 41 gallbladder carcinomas. The correlation between expression of CDX2 and clinicopathological factors, including overall survival, tumor location, tumor stage, and degree of tumor differentiation, was examined in patients with BTC.', 'In total, 27 of the 164 (16.46%) patients with BTC expressed CDX2. The frequency of CDX2 expression was much higher in the extrahepatic cholangiocarcinomas (22.45%) and gallbladder carcinomas (29.27%) than in the intrahepatic cholangiocarcinomas (5.41%), the difference being statistically significant (P = 0.002). Factors influencing survival on univariate analysis were tumor stage (P < 0.00001), degree of tumor differentiation (P = 0.0002), and CDX2 expression (P = 0.01). On multivariate analysis using the Cox proportional hazard model, CDX2 expression and tumor stage were independent prognostic factors in patients with BTC.\Question: Is expression of the caudal-type homeodomain transcription factor CDX2 related to clinical outcome in biliary tract carcinoma?
Expression of CDX2 was an independent indicator of outcome in patients with BTC in addition to tumor stage and tumor differentiation. The mechanism by which CDX2 expression influences behavior of biliary tract carcinoma needs further investigation.

Context: To examine whether differences emerged when the Chinese version of the Movement-Specific Reinvestment Scale (MSRS-C) was administered to community-dwelling older adults with instructions to respond in the context of "general" movements, walking, using chopsticks or dressing. Furthermore, the difference between the six-point Likert scale and four-point Likert scale response formats of the MSRS-C was investigated.', 'The study was implemented in the community of Hong Kong with 52 older adults (mean age 77.4 years). Telephone interviews were carried out on two occasions for each participant. Participants provided a verbal response to each of 10 questions from the MSRS-C with different response formats (i.e., six-point or four-point Likert Scales) and different instructions in the response context (i.e. general, walking, using chopsticks, dressing). The sequence of response format and context was randomized for each participant.', 'Older fallers scored significantly higher on the MSRS-C (general) with six-point or four-point response formats than non-fallers. The MSRS-C (general) and MSRS-C (walking) were not statistically different, and showed good discriminative power for previous older fall status (older fallers or older non-fallers). However, MSRS-C (chopsticks) and MSRS-C (dressing) failed to differentiate older fallers from older non-fallers.\Question: Do instructions influence response to the Chinese version of the Movement-Specific Reinvestment Scale in community-dwelling older adults?
Both the MSRS-C (general) and MSRS-C (walking) with a six-point or a four-point response format showed good discrimination of older fallers from non-fallers. Older adults might respond to the MSRS-C with respect to the most challenging movements (e.g. fall-related movements) in their daily living. Geriatr Gerontol Int 2015; ●●: ●●-●●.

Context: To evaluate manual lymphatic drainage (MLD) and active exercise effects on lymphatic alterations of the upper limb (UL), range of motion (ROM) of shoulder, and scar complications after breast cancer surgery.', 'Clinical trial.', 'Health care center.', 'Women (N=105) undergoing radical breast cancer surgery who were matched for staging, age, and body mass index.', 'Women (n=52) were submitted to MLD and 53 to active exercises for UL for 1 month and followed up.', 'Shoulder ROM, surgical wound inspection and palpation, UL circumference measurements, and lymphoscintigraphy were performed in preoperative and postoperative periods.', 'There was no significant difference between groups with regard to wound healing complications, ROM, and UL circumferences. After surgery, 25 (48.1%) of the MLD group and 19 (35.8%) of the active exercise group showed worsening in radiopharmaceutical uptake velocity, whereas 9 (17.3%) of the MLD group and 11 (20.8%) of the active exercise group showed improved velocity (P=.445). With regard to uptake intensity, 27 (51.9%) of the MLD group and 21 (39.6%) of the active exercise group showed worsening whereas 7 (13.5%) of the MLD group and 7 (13.2%) of the active exercise group showed some improvement (P=.391). The presence of collateral circulation was similar in both groups at both time points evaluated. The active exercise group had a significant increase in postoperative liver absorption (P=.005), and the MLD group had a significant increase in postoperative dermal backflow (P=.024).\Question: Do manual Lymphatic Drainage and Active Exercise Effects on Lymphatic Function Translate Into Morbidities in Women Who Underwent Breast Cancer Surgery?

MLD and active exercise effects are equivalent with regard to morbidity. Minor changes in lymphatic function associated with either MLD or active exercises were not related to patients' symptoms or signs.
