The described gemcitabine plus cisplatin combination was found to be an active and tolerable salvage regimen in patients with taxane resistant metastatic breast cancer.

Nonocclusive mesenteric ischemia (NOMI) is known to occupy about 25% to 60% of intestinal infarction. NOMI has been reported to be responsible for 9% of the deaths in the dialysis population and the postulated causes of NOMI include intradialytic hypotension, atherosclerosis and medications, such as diuretics, digitalis and vasopressors. Clinical manifestations, such as fever, diarrhea and leukocytosis, are nonspecific, which makes early diagnosis of NOMI very difficult. Case: A 66-year-old woman on maintenance hemodialysis for 5 years was admitted with syncope, abdominal pain and chilly sensation. Since 7 days prior to admission, blood pressure on the supine position during hemodialysis had frequently fallen to 80/50 mmHg. Four days later, she complained of progressive abdominal pain. Rebound tenderness and leukocytosis (WBC 13900/mm3) with left shift were noted. Stool examination was positive for occult blood. Abdominal CT scan showed a distended gall bladder with sludge. Under the impression of acalculous cholecystitis, she was operated on. Surgical and pathologic findings of colon colon were compatible with NOMI. Because of recurrent intradialytic hypotension, we started midodrine 2.5 mg just before hemodialysis and increased the dose up to 7.5 mg. After midodrine therapy, blood pressure during dialysis became stable and the symptoms associated with hypotension did not recur. Conclusion: As NOMI may occur within several hours or days after an intradialytic hypotensive episode, abdominal pain should be carefully observed and NOMI should be considered as a differential diagnosis. In addition, we suggest that midodrine be considered to prevent intradialytic hypotensive episodes.

We performed a single-institution phase II study to evaluate the efficacy and toxicities of vinorelbine monotherapy in patients previously treated with anthracyclines and taxanes. Vinorelbine was administered at a dose level of 25 mg/m² intravenously on days 1, 8, 15 and 22, every four weeks, and responses were assessed after every two cycles of treatment. All of the patients had previously been treated with anthracyclines and taxanes. A total of 26 patients were enrolled in this study between April 2004 and August 2009. The median age of the patients was 47 years (range, 37 to 71 years), and 80.8% had an Eastern Cooperative Oncology Group performance status of 0 or 1. Out of 24 evaluable patients, five partial responses were observed, giving an overall response rate of 20.8%, with a median response duration of 2.8 months. The median time to progression was 3.7 months (range, 0.5 to 22.6 months), and median overall survival duration was 10.4 months (range, 1.3 to 57.6 months). The major toxicities observed were neutropenia, anemia and peripheral neuropathy. Grade 3 or 4 hematologic toxicities included neutropenia in 18 patients (69.2%) and anemia in four patients (15.3%). Grade 1 or 2 peripheral neuropathy was observed in 11 patients (42.3%), however there were no cases of grade 3 or 4 peripheral neuropathy. The results of this study indicate that vinorelbine monotherapy was feasible regimen with manageable toxicities in patients with metastatic breast cancer who were previously exposed to anthracyclines and taxanes.

YKL-40 is a glycoprotein involved in cellular growth, migration, and the inflammatory process. Elevation in serum levels of YKL-40 has been associated with worse prognosis in various cancers, including breast cancer. Given that the clinical significance of YKL-40 expression in breast cancer tissue is unclear, we aimed to determine the prognostic value of YKL-40 expression in breast cancer tissue using immunohistochemistry. We performed tissue microarray (TMA) analysis of 425 breast cancer tissues collected during operation. Immunohistochemical staining was performed to measure expression of YKL-40 and several breast cancer biomarkers, such as aldehyde dehyadrogenase1, TGF-beta, and Gli-1 as well as hormonal receptor and Her-2/neu status. Statistical analysis of the relationship of YKL-40 expression with clinicopathological characteristics was performed for 390 TMA samples. YKL-40 was expressed to varying degrees in 84.9% of breast cancer tissues. YKL-40 expression was correlated with estrogen receptor and progesterone receptor negativity and was positively correlated with TGF-beta and Gli-1 expression. Strong YKL-40 expression was associated with a larger proportion of Her-2/neu-enriched and basal-like tumors. The results of this study demonstrate that YKL-40 expression in breast cancer tissues is associated with hormone receptor negativity and Her-2/neu-enriched molecular subtypes of breast cancer, and therefore could be considered a poor prognostic predictor.

Primary adenosquamous carcinoma of the liver is a very rare type of cholangiocarcinoma and is defined as a cancer containing both squamous and adenomatous components in the same lesion. Recently, we experienced a primary adenosquamous carcinoma of the liver presented as liver abscess. A 63-year-old man was presented with a 4-day history of fever and chill. The radiologic study showed a 4 cm-sized, central hypoattenuated mass with peripheral rim enhancement in the left lobe of the liver. Ultrasonography-guided aspiration and biopsy suggested an adenocarcinoma with abscess in the liver. At laparotomy, the tumor occupied the left lobe of the liver and invaded the right diaphragm. An extended left lobectomy and a partial excision of the involved diaphragm were done. Grossly, the tumor was 6×5×5 cm in size and had an eccentric necrosis. Microscopically, the tumor was composed of adenocarcinoma and squamous cell carcinoma with a transitional area.

Although various new agents have been developed for the treatment of patients with metastatic breast cancer (MBC), overall survival rates have changed little in the last half century. We conducted meta-analysis to verify the clinical efficacy of bevacizumab for the salvage treatment of MBC. Event-based hazard ratios (HR) with 95% confidence intervals (95% CIs) were derived, and a test of heterogeneity was applied. Four studies, with a total of 2,860 patients, met the inclusion criteria for analysis. The pooled results of clinical efficacies were: HR for progression free survival 0.69 (95% CI, 0.58-0.81, z = 4.54, P <0.001); HR for overall survival 0.92 (95% CI, 0.82-1.03, z =1.44, P = 0.15); and HR for the clinical objective response rate 1.53 (95% CI, 1.37-1.71, z = 7.37, P < 0.001). In terms of overall survival, subgroup analysis demonstrated statistically significant improvement for the bevacizumab combination in the initial therapy subgroup (HR, 0.878; 95% CI, 0.771-0.999, z = 1.98, P = 0.048). Hypertension and proteinura were more common in the bevacizumab combination arm; however, these toxicities were managed with therapy. In conclusion, meta-analysis suggested benefits of a carefully managed bevacizumab-containing salvage regimen for patients with histologically or cytologically confirmed Her-2 negative MBC who have not received previous cytotoxic therapy. This treatment could improve both progression free survival and overall survival rates.
