Comparative StudyClinical and economic evaluation of first-line therapy with FOLFIRI or modified FOLFOX6 for metastatic colorectal cancer.
Recently, significant progress in treatment of metastatic colorectal cancer has been achieved. Either FOLFIRI (fluorouracil, leucovorin and irinotecan) or modified FOLFOX6 (fluorouracil, leucovorin and oxaliplatin, oxaliplatin dose 85 mg/m(2)) is selected as first-line therapy in clinical practice in Japan. However, economic burden of colorectal cancer is considerable. ⋯ FOLFIRI is inexpensive in the initial stage of treatment which a number of patients can receive chemotherapy than modified FOLFOX6 as first-line therapy for metastatic colorectal cancer in Japanese national insurance system.

Comparative StudyA comparison of HER2/neu gene amplification and its protein overexpression between primary breast cancer and metastatic lymph nodes.
Breast cancer is a heterogeneous disease. The aim of this prospective study, in which fluorescence in situ hybridization was used to determine human epidermal growth factor receptor 2 status in primary breast cancers and in the lymph node metastases, was to verify the stability of human epidermal growth factor receptor 2 status in the following steps of neoplastic progression of breast cancer, which is fundamental for an appropriate therapeutic approach. ⋯ This study revealed that fluorescence in situ hybridization resulted in a high concordance of 83.3% between the human epidermal growth factor receptor 2 manifestation (fluorescence in situ hybridization-positive status) in primary tumors and that in metastatic lymph nodes, demonstrating that it is appropriate to determine whether and how to apply treatment by trastuzumab based on the results of evaluation of human epidermal growth factor receptor 2 expression.

Case ReportsNeoadjuvant chemotherapy with paclitaxel plus platinum followed by radical surgery in early cervical cancer during pregnancy: three case reports.
To date, only seven women with Stage Ib1 to IIb cervical cancer during pregnancy treated with neoadjuvant chemotherapy followed by radical surgery have been reported. We describe three cases of pregnant women with Stage Ib1 to IIa cervical cancer who were treated with paclitaxel plus platinum neoadjuvant chemotherapy followed by radical surgery. The first patient had a Stage Ib1 small cell neuroendocrine carcinoma of the cervix, the second had a Stage IIa, 8 cm squamous cell carcinoma of the cervix and the third had a Stage Ib2 squamous cell carcinoma and positive lymph nodes. ⋯ Two of these patients developed recurrences and one died due to progressive disease at 49 months. All neonates were healthy and had no abnormalities. In conclusion, neoadjuvant chemotherapy with paclitaxel and platinum followed by radical surgery may be an option for pregnant women with invasive cervical cancer.
