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.

[EX Q]: Context: Silibinin exerts hepatoprotective, anti-inflammatory and anti-fibrotic effects. Several pre-clinical studies have shown anti-tumoral activity of silibinin in breast cancer cell lines.', "We present the case of a heavily pre-treated breast cancer patient with extensive liver infiltration. The patient presented with progressive liver failure despite several chemotherapy treatments, including paclitaxel, capecitabine and vinorelbine. After four cycles of a fourth-line chemotherapy treatment consisting of carboplatin and gemcitabine, the patient's liver blood test results deteriorated to life-threatening levels. The compassionate use of Legasil®, a new commercially available nutraceutical product containing a new silibinin formulation, was offered to the patient according to article 37 of the 2013 Declaration of Helsinki. After treatment initiation, the patient presented clinical and liver improvement, which permitted the patient to continue palliative chemotherapy.\Question: Does silibinin administration improve hepatic failure due to extensive liver infiltration in a breast cancer patient?
[EX A]: This is the first case report of a clinical benefit of silibinin administration in a breast cancer patient.

[EX Q]: Context: To determine the association of statin use with oncological outcomes and risk of pathologic upgrading following radical prostatectomy.', 'Using a prospectively populated database of 3042 men who underwent open radical prostatectomy, patients were grouped according to reported statin use at the time of surgery. The primary outcome was time to biochemical recurrence. The secondary outcome was risk of pathologic upgrading among a subset of 1256 patients with Gleason pattern 3\u2009+\u20093\u2009=\u20096 on biopsy. A multivariable Cox model was used to assess risk of biochemical recurrence, and multivariable logistic regression was used to assess risk of pathologic upgrading.', 'Eight hundred twenty-four men (27%) reported statin use at the time of radical prostatectomy. Statin users were older and had higher body mass index, higher Charlson Comorbidity Index, and lower pretreatment prostate-specific antigen values than statin nonusers. Over a median follow-up of 70 months (interquartile range: 36-107), a total of 455 men (15%) experienced biochemical recurrence. Statin use was not associated with biochemical recurrence (adjusted hazard ratio: 1.06, 95% confidence interval: 0.86-1.31). Of those men with biopsy Gleason 3\u2009+\u20093\u2009=\u20096 disease, 647 (52%) were upgraded to higher grade disease following radical prostatectomy; however, statin use was not associated with pathologic upgrading (adjusted odds ratio: 0.78, 95% confidence interval: 0.58-1.04).\Question: Is preoperative Statin Use at the Time of Radical Prostatectomy Associated With Biochemical Recurrence or Pathologic Upgrading?
[EX A]: Preoperative statin use at the time of radical prostatectomy was not associated with biochemical recurrence or risk of pathologic upgrading in this cohort. These data add to the existing body of literature suggesting that statin use is not associated with more favorable clinical outcomes following radical prostatectomy.

[EX Q]: Context: Induction of delayed hypersensitivity reactions by red tattoos has been occasionally reported. Little is known about the inks used. Azo pigments have been implicated in some instances, but there is only one reported case involving quinacridones.', 'To describe the clinical and pathological features and outcome of skin reactions induced by red tattoo pigments.', 'Six patients with a cutaneous reaction induced by a red tattoo pigment underwent biopsy and prick and patch testing with the inks supplied.', 'We observed seven reactions in the 6 patients. Histology showed various patterns: three lichenoid, two eczematous, and two pseudolymphomatous. Five reactions occurred with azo pigments, and two with quinacridones, in both cases with Violet 19 and Red 122. Four inks were tested. Only one patch test gave a positive result at a late reading (day 7). Prick tests gave negative results. The reactions required various treatments, including laser treatment for 2 patients. Activation of the reaction in 1 case was transient.\Question: Do azo pigments and quinacridones induce delayed hypersensitivity in red tattoos?
[EX A]:
Azo pigments and quinacridones both triggered reactions with similar clinical aspects but with varying histological findings. Patch and prick test results were disappointing with both. Reactions occurred following laser use in 1 case.
