The aim of this study was to determine the maximum-tolerated dose and dose-limiting toxicity (DLT) of combination therapy with gemcitabine and S-1 in patients with advanced pancreatic cancer. ⋯ Combination chemotherapy with gemcitabine and S-1 was well tolerated and showed good antitumor activity in the treatment of pancreatic cancer. We recommend a gemcitabine dose of 1,000 mg/m(2)/week and an S-1 dose of 80 mg/m(2)/day in further studies with this schedule.

Newer-generation intravenous bisphosphonates have resulted in the reduction of skeletal-related complications, i.e. skeletal-related events (SREs) such as pain, hypercalcemia, pathologic fractures and spinal cord and nerve compression, as well as improvements in the quality of life in patients with metastatic bone disease who are likely to have a prolonged clinical course. Highly potent, nitrogen-containing bisphosphonates such as zoledronic acid reduce SREs in patients with bone metastases from other solid tumors (including lung cancer). Part one of our review discussed the mechanisms of action by bisphosphonates as well as potential roles for bone markers and imaging in lung cancer. In this article, part two of our review, we examine the economic and clinical impact of bisphosphonates in lung cancer, with a focus on the potential role of newer-generation bisphosphonates in the management of advanced, metastatic bone disease of lung cancer.

Because of its proven efficacy profile based on long-term data, tamoxifen has been the standard adjuvant endocrine therapy for hormone-sensitive early breast cancer for the past 30 years. However, there is well-established evidence that long-term use of tamoxifen is associated with serious side effects. As adjuvant endocrine therapy is generally administered for long periods of time, the safety and tolerability of agents used in this setting are of particular importance. ⋯ The AIs have differing pharmacological profiles, which may translate into dissimilar adverse event profiles in the adjuvant treatment setting, but patient follow-up in most trials is relatively short to make a valid comparison. It cannot, therefore, be assumed that all AIs will be equally well tolerated in the adjuvant setting. Further data on the long-term safety of AIs other than anastrozole are therefore required to allow overall risk:benefit assessments on these agents to be made.

Multicenter Study Clinical Trial
A phase II study of epirubicin, cisplatin and capecitabine combination chemotherapy in patients with metastatic or advanced gastric cancer.
The purpose of this study was to evaluate the antitumor activity and safety of an epirubicin, cisplatin, and capecitabine (ECX) combination in patients with metastatic or advanced gastric cancer. ⋯ ECX combination regimen showed high anti-tumor activity with a tolerable toxicity pattern as a front-line chemotherapy for patients with metastatic or advanced gastric cancer.

Clinical Trial
Phase I study of a combination of s-1 and weekly paclitaxel in patients with advanced or recurrent gastric cancer.
A phase I study of weekly intravenous paclitaxel combined with a fixed dose of S-1, a dihydropyrimidine-dehydrogenase-inhibitory oral fluoropyrimidine, was conducted for patients with advanced or recurrent gastric cancer (ARGC). Endpoints of this study were to examine the toxicity profile OF this regimen and to determine the recommended dose (rd) of paclitaxel. ⋯ A combination of S-1 and weekly paclitaxel was feasible and well tolerated, and is suggested to produce a worthwhile response in ARGC. These results warrant further investigation, and a phase II study has already been started.
