First-line Gemcitabine Treatment of Physician's Choice for Metastatic Breast Cancer: A Prospective Cohort Study.

Background/aim: This study aimed to investigate the efficacy of first-line gemcitabine monotherapy for metastatic breast cancer (MBC) and its effect on health-related quality of life (HRQoL) compared with treatment of physician's choice (TPC).

Patients And Methods: We enrolled 96 patients into the first-line gemcitabine group (n=47) or other treatment of physician's choice (TPC) group (n=49) from May 2010 to April 2013. HRQoL was evaluated every 4 weeks.

Negative feedback regulation of calcineurin-dependent Prz1 transcription factor by the CaMKK-CaMK1 axis in fission yeast.

Calcium signals trigger the translocation of the Prz1 transcription factor from the cytoplasm to the nucleus. The process is regulated by the calcium-activated phosphatase calcineurin, which activates Prz1 thereby maintaining active transcription during calcium signalling. When calcium signalling ceases, Prz1 is inactivated by phosphorylation and exported to the cytoplasm.

Breast cancer manifested by hematologic disorders.

Breast cancer is the most common type of cancer in women. However, it is very rarely manifested as hematologic disorders. A 35-year-old woman was admitted because of disseminated intravascular coagulation.

The topoisomerase II alpha gene status in primary breast cancer is a predictive marker of the response to anthracycline-based neoadjuvant chemotherapy.

This study aimed at evaluating the usefulness of topoisomerase II alpha (TOP2A) for predicting the effect of anthracycline-based neoadjuvant chemotherapy in breast cancer. The TOP2A status was examined using fluorescent in situ hybridization (FISH) in 14 pre-chemotherapeutic breast cancer tissues, and was also assessed by immunohistochemistry (IHC) in 14 pairs of pre- and post-chemotherapeutic breast cancer specimens. TOP2A gene aberration by IHC tended to show a correlation with pathological responses but this was not statistically significant (p=0.

Feasibility of AC/EC followed by weekly paclitaxel in node-positive breast cancer in Japan.

Unlabelled: The feasibility and efficacy of adriamycin or epirubicin in combination with cyclophosphamide followed by weekly paclitaxel (AC/EC-weekly PAC) as adjuvant chemotherapy for breast cancer was investigated.

Patients And Methods: Node-positive breast cancer was treated with AC/ EC-weekly PAC, namely AC at 60/600 mg/m(2) or EC at 90/600 mg/m(2) x4 at three-week intervals, followed by weekly PAC (80 mg/m(2)) x 12, namely four cycles of single weekly administration for three weeks followed by a one-week rest (3 x 4 PAC) or single weekly administration for 12 consecutive weeks (12 PAC).

Results: One hundred and three of 109 consecutive patients enrolled were analyzed, of whom 96 (93.

Tumor doubling time and local immune response to hepatic metastases from colorectal cancer.

Background And Objectives: A number of studies have investigated the role of tumor-infiltrating lymphocytes in cancer, yet the local immune response to hepatic colorectal cancer metastasis remains unclear. As the tumor doubling time (DT) of hepatic colorectal cancer metastases is a good index of tumor growth, we examined the correlation between tumor DT and the local immune response by phenotype in hepatic colorectal cancer metastases.

Methods: Tumor DT and local immune response were examined in 20 patients with hepatic colorectal cancer metastases by analyzing tumor-infiltrating lymphocytes using flow cytometry or immunohistochemical studies.

Contrast harmonic imaging of canine hepatic tumors.

Six adult healthy Beagles were used to investigate the hepatic perfusion dynamics of Levovist, a contrast agent used in contrast harmonic imaging (CHI). In addition, 8 dogs with hepatocellular carcinoma (HCC) and 2 dogs with metastatic hepatic hemangiosarcoma (HSA) were used to characterize both the CHI findings with Levovist. In the Beagles, the start of intravenously injected Levovist into the aorta between the cranial mesenteric and renal arteries and the portal vein at the hepatic hilum were 5.

[Efficacy of circadian chronotherapy via hepatic arterial infusion].

For hepatectomy after neoadjuvant chemotherapy (NAC), we applied circadian chronotherapy via the hepatic artery for multiple bilobar liver metastases from colorectal cancer. Four patients underwent chronotherapy and 16 patients underwent flat infusion therapy (5 day q 2 weeks, 4 or more courses). We used 2 drugs, (5-fluorouracil (5-FU) and l-leucovorin (l-LV)), and partially added cisplatin (CDDP) in the flat infusion group.
