Activation of the mammalian target of rapamycin (mTOR) pathway has been demonstrated in sarcoma. Trials using mTOR inhibitor in sarcoma have shown low objective response rates but progression-free survival (PFS) rates suggest cytostatic effects. The combination of sirolimus and cyclophosphamide demonstrated synergistic anti-sarcoma activity in preclinical models; therefore, we conducted a phase II trial of sirolimus and cyclophosphamide in patients with advanced sarcoma. ⋯ Sirolimus and cyclophosphamide were tolerated by the majority of patients. About 20% of patients had stable sarcoma for at least 6 months but objective tumour response was infrequent.

Oxaliplatin is a key drug in the treatment of colorectal cancer, but it causes acute and chronic neuropathies in patients. Goshajinkigan (GJG) is a Kampo medicine that is used for the treatments of several neurological symptoms including pain and numbness. More recently, GJG has been reported to prevent the oxaliplatin-induced peripheral neuropathy in clinical studies. ⋯ Single administration of GJG reduced both cold hyperalgesia and mechanical allodynia after the development of neuropathy. In addition, GJG did not affect the anti-tumour effect of oxaliplatin in the tumour cells or tumour cells-implanted mice. These results suggest that GJG relieves the oxaliplatin-induced cold hyperalgesia and mechanical allodynia without affecting anti-tumour activity of oxaliplatin, and, therefore, may be useful for the oxaliplatin-induced neuropathy in clinical practice.
