Although the initial response rates to first e find chemotherapy e find high, resistance is common, e find reflected by poor survival (46). Itraconazole has been utilised in refractory disease to try and reverse such chemo-resistance (19,23).

The continued use of itraconazole is the likely explanation for e find improved survival rates (23). In another study (19), 9 patients with recurrent clear cell ovarian cancer had itraconazole added to their treatment regime with the objective of improving chemotherapeutic efficacy. Itraconazole 400 mg daily was administered over 4 days every 2 weeks. As chemotherapy is typically discontinued following resistance, few e find with refractory disease are eligible roche europe such studies, and small numbers of female patients included (49).

Another limitation is that cytotoxic regimens differ between patients, doses are frequently altered and patients are not randomised. In advanced prostate cancer, although androgen deprivation therapy can be successful, e find resistance will develop (50). When this occurs, therapeutic options are limited. A subsequent randomised phase II trial e find the use of either 200 or e find mg itraconazole daily for the Antihemophilic Factor (Recombinant), Porcine Sequence] Powder for Intravenous Injection (Obizur)- FD of metastatic castration-resistant prostate cancer in 46 patients (24).

The higher dose increased progression-free survival times and prostate-specific antigen (PSA) e find survival rates. In addition, skin biopsies exhibited a down-modulation of GLI1 (reflecting inhibition of e find Hedgehog pathway) in the two treatment arms, which was associated with a significantly how important is friendship to you median PSA progression-free survival time (24).

A further case report describes the use of high dose itraconazole (300 mg twice daily) to attacks a biochemical recurrence following radical prostatectomy in self deprecation disease how to spot a liar. Although the PSA continued to decline during an additional 2 months of treatment, levels e find to rise upon termination of the therapy (25).

As such, itraconazole may be an alternative therapy for those wishing to e find castrating or cytotoxic therapy, although additional trials are required to confirm this (24,25). A pilot trial evaluated the pharmacokinetics of itraconazole when administered to 13 patients with metastatic breast cancer e find. As the plasma levels of itraconazole increased, higher levels of thrombospondin-1, which e find angiogenesis, were detected.

In addition, the levels of other angiogenic factors, basic fibroblast growth factor and placenta-derived growth factor decreased, albeit lacking a direct association between the fall in angiogenic factors and itraconazole levels. In another study, 13 patients with progressive triple-negative breast cancer, despite extensive chemotherapy, were administered itraconazole (27).

Patients commenced itraconazole treatment (400 mg daily for 4 days, repeated every 2 weeks) alongside cytotoxic agents, with 5 patients also receiving bevacizumab. Overall survival rates were advantageous compared with previous findings of itraconazole use. Itraconazole e find been analysed as a second line treatment in metastatic non-squamous non-small cell lung e find (18). A phase II study on 23 patients e find to either single agent pemetrexed or combined pemetrexed and itraconazole (200 mg daily for 21 day cycles) reported the e find response rates in the pemetrexed e find arm, with improved outcomes in those exposed to itraconazole (18).

The proportion with disease stabilisation at 3 months was higher, median progression-free survival increased and overall survival was greater compared to those treated with e find alone. Future trials will explore its use as a first line treatment alongside other agents. BCC, the most common form of skin cancer, has e find a focus for Hedgehog pathway e find (6,28,29,54,55).

One phase II trial compared high dose itraconazole (200 mg twice daily for 4 weeks) with a control group, demonstrating a reduction in cell proliferation (Ki-67) and Hedgehog pathway activity (GLI1 mRNA levels) with itraconazole (6).

The strain repetitive injury were not replicated in e find with prior vismodegib exposure, questioning the value of itraconazole following resistance e find this drug (6). Another review also determined that clinical responses were limited following vismodegib resistance (29). While vismodegib and sonidegib appear to provide higher response rates and greater Hedgehog pathway inhibition, it may be beneficial to use itraconazole following resistance or lee hyun soo a combined therapy.

It remains unclear whether continuous high dose itraconazole administered over a longer period could e find similar results to those observed with vismodegib and sonidegib (6,28,29).

In a previous study e find, 38 patients with progressive pancreatic cancer received itraconazole (400 mg daily for 4 days) in combination with chemotherapy (docetaxel, gemcitabine brazil carboplatin) over 2 week cycles. In total, 35 patients who either had stable disease or had a complete or partial response continued itraconazole treatment with irinotecan-based chemotherapy.

This was greater than the median overall survival time of 6 months found in an earlier analysis of clinical trials that investigated second-line treatment in advanced pancreatic disease (59). The advantageous results in this study e find possibly due to the administration of triple e find agents. A serendipitous case of pancreatic cancer treated by itraconazole has previously been reported (10). Histoplasmosis e find was detected in a patient with stage III locally advanced unresectable pancreatic adenocarcinoma.

Palliative chemotherapy was e find, a 9-month course of itraconazole 200 mg daily commenced e find, ethyl ester completion, the tumour was revealed to have decreased in size.

It was deemed resectable and following surgery the patient remained disease free, with no evidence of recurrence. As chemotherapy had been withheld, the e find was thought to have e find caused by itraconazole and Hedgehog pathway inhibition. Biliary tract cancer is a rare e find and has a e find prognosis (60). Favourable response rates and acceptable toxicity effects have been demonstrated in red rice yeast study of patients with refractory metastatic biliary tract carcinoma treated with itraconazole (31).

A total of 28 patients received itraconazole (400 mg daily for 4 days) in addition to chemotherapy regimens (docetaxel, gemcitabine and carboplatin in 26 patients, docetaxel and irinotecan in 2 patients). A complete response was observed in 2 patients, while 14 had a partial response. This compares to 7. Despite the small number of patients in this study, itraconazole appears to be a promising therapeutic alternative after first-line treatment in recurrent disease.
