Effect of HER-2/neu overexpression on chemoresistance and prognosis in ovarian carcinoma.

AIM: To investigate the effect of HER-2/neu protein overexpression on chemoresistance and prognosis in patients with epithelial ovarian carcinoma. METHODS: A total of 141 ovarian carcinoma tissues surgically resected between 1987 and 2003 were assessed by immunohistochemistry (IHC). The characteristic of the patients and immunohistochemical results were compared by chi2-test. Survival analysis was performed by the Kaplan-Meier method and the log-rank test. RESULTS: HER-2/neu overexpression was detected in 18 cases (12.8%). There were no significant differences in histopathological subtypes (P = 0.3550), FIGO stages (P = 0.8858), or residual tumor size at first surgery (P = 0.6607) between the cases with HER-2/neu overexpression and the cases without HER-2/neu overexpression. Among the 58 cases which responded to chemotherapy, only five cases (8.6%) showed HER-2/neu overexpression. However, among the 38 cases which did not respond to chemotherapy, eight cases (21.1%) showed HER-2/neu overexpression. Overexpression of HER-2/neu had a tendency to relate with chemoresistance of epithelial ovarian carcinoma, but there were no statistically significant differences (P = 0.0817). No association was observed between HER-2/neu overexpression and cumulative survival rate (P = 0.4970). CONCLUSIONS: The results of the current study show that although HER-2/neu overexpression has a tendency to be associated with chemoresistance, it can not be a prognostic factor for the patients with epithelial ovarian carcinoma.

Outbreaks of multidrug-resistant Pseudomonas aeruginosa in community hospitals in Japan.

We previously reported an outbreak in a neurosurgery ward of catheter-associated urinary tract infection with multidrug-resistant (MDR) Pseudomonas aeruginosa strain IMCJ2.S1, carrying the 6'-N-aminoglycoside acetyltransferase gene [aac(6')-Iae]. For further epidemiologic studies, 214 clinical isolates of MDR P. aeruginosa showing resistance to imipenem (MIC >or= 16 microg/ml), amikacin (MIC >or= 64 microg/ml), and ciprofloxacin (MIC >or= 4 microg/ml) were collected from 13 hospitals in the same prefecture in Japan. We also collected 70 clinical isolates of P. aeruginosa that were sensitive to one or more of these antibiotics and compared their characteristics with those of the MDR P. aeruginosa isolates. Of the 214 MDR P. aeruginosa isolates, 212 (99%) were serotype O11. We developed a loop-mediated isothermal amplification (LAMP) assay and a slide agglutination test for detection of the aac(6')-Iae gene and the AAC(6')-Iae protein, respectively. Of the 212 MDR P. aeruginosa isolates, 212 (100%) and 207 (98%) were positive in the LAMP assay and in the agglutination test, respectively. Mutations of gyrA and parC genes resulting in amino acid substitutions were detected in 213 of the 214 MDR P. aeruginosa isolates (99%). Of the 214 MDR P. aeruginosa isolates, 212 showed pulsed-field gel electrophoresis patterns with >or=70% similarity to that of IMCJ2.S1 and 83 showed a pattern identical to that of IMCJ2.S1, indicating that clonal expansion of MDR P. aeruginosa occurred in community hospitals in this area. The methods developed in this study to detect aac(6')-Iae were rapid and effective in diagnosing infections caused by various MDR P. aeruginosa clones.

Characteristic expression of globotriaosyl ceramide in human ovarian carcinoma-derived cells with anticancer drug resistance.

The transporter protein genes and lipids in human ovarian carcinoma-derived KF28 cells with anticancer-drug-sensitive properties were compared with those in resistant cells, taxol-resistant KF28TX, cisplatin-resistant KFr13, and taxol- and cisplatin-resistant KFr13TX, to identify the molecules required for anticancer-drug resistance. In accordance with previous reports, taxol and cisplatin resistance was closely correlated with expression of the multidrug resistance 1 and bile acid export pump, and multidrug resistance-associated protein 2 genes, respectively. In addition, we found a distinct difference in glycosphingolipids between the sensitive and resistant cells. Although GlcCer was the major glycolipid (83.0%) in sensitive cells, GalCer, LacCer and, particularly, Gb(3)Cer were characteristically increased in all resistant cells, irrespective of whether the resistance was to taxol or cisplatin, and comprised 65-84% of total glycosphingolipids. GM3, which was present at 0.04 microg/mg dry weight in the sensitive cells, showed a twofold increase in the taxol-resistant cells, but was absent in the cisplatin-resistant cells. The altered glycolipid composition was proven to be due to enhanced or suppressed expression of the respective sugar transferase genes. In addition, the ceramide moiety of ceramide monohexoside in the sensitive cells constituted 83% of non-hydroxy fatty acids, but that in the resistant cells comprised 67-74% of alpha-hydroxy fatty acids. Thus, cells containing Gb(3)Cer with alpha-hydroxy fatty acids were found to survive selectively in the presence of taxol and cisplatin, and modification of the glycolipid structure was revealed to occur in association with anticancer-drug resistance.

Mice with blunted hypoxic ventilatory response are susceptible to respiratory disturbance during hypoxia.

Hypoxia causes a life-threatening situation, and the ventilatory response to hypoxia plays an important role in preventing death. We have hypothesized that persons with a blunted hypoxic ventilatory response may have a weak defense response to hypoxic episodes and be susceptible to fatal respiratory disturbances. However, precise correlations between the hypoxic ventilatory response and respiratory disturbances are not well understood. In the present study we examined the hypoxic and hypercapnic ventilatory responses in nine inbred mouse strains (A/J, AKR/N, BALB/c, C3H/He, C57BL/6, DBA/2, NZW, SWR/J, and 129Sv). Breathing frequency, tidal volume and minute ventilation of unanesthetized and unrestrained mice were assessed by whole body plethysmography. Age-matched mice were exposed for 3 min to 10% O(2) in N(2) gas or 10% CO(2) in hyperoxic gas to determine the acute ventilatory response to chemical stimuli. Basal respiratory variables and hypoxic ventilatory responses differed among the strains, but the hypercapnic ventilatory response did not differ. The hypoxic ventilatory response was the highest in AKR/N mice and the lowest in SWR/J mice. These findings suggest that genetic factors may have influenced the hypoxic ventilatory response but not the hypercapnic ventilatory response. To examine the effects of severe hypoxic stress on the respiratory cycle, we exposed the strain with the highest or lowest hypoxic ventilatory response to 6% O(2) in N(2) until the onset of apnea. The "appearance time of apnea", which is defined as the time from the hypoxic loading to the onset of apnea, was shorter in the SWR/J strain than in the AKR/N strain. We suggest that a lower hypoxic ventilatory response may be a risk factor for apnea under hypoxia.

Inhibitory effects of bisphosphonates on the proliferation of human ovarian cancer cell lines and the mechanism.

Bisphosphonates are now well established as successful agents for the prevention and treatment of postmenopausal osteoporosis and corticosteroid-induced bone loss. Bisphosphonates have also recently become important in the management of cancer-induced bone disease, and they now have a widely recognized role for patients with multiple myeloma and bone metastases secondary to breast cancer and prostate cancer. Recent studies suggest that, besides the strong antiosteoclastic activity, the efficacy of such compounds in the oncological setting could also be due to direct anti-tumor effect. However, the effect of bisphosphonates to ovarian and endometrial cancers has not been elucidated. Thus, we examined the direct effect of bisphosphonates on the various ovarian cancer cell lines. Except for etidronate, all of bisphosphonates examined had the direct inhibitory effects on proliferation of all ovarian cancer cell lines used. Especially, pamidronate had the most marked inhibitory effect and inhibited dose-dependently the proliferation of ovarian cancer cell lines. KFr 13 cells among ovarian cancer cell lines used was the most sensitive to pamidronate and the caspase 3 activity was markedly stimulated by treatment with pamidronate, suggesting induction of apoptosis.

Clinical significance of immunocytochemistry for PIK3CA as a carcinogenesis-related marker on liquid-based cytology in cervical intraepithelial neoplasia.

The catalytic subunit alpha of phosphatidylinositol 3-kinase (PIK3CA) has been expected to play a role as an important oncogene in uterine cervical carcinoma, whose expression in non-invasive lesions has received considerable attention. We investigated the potential of PIK3CA as a carcinogenesis-related marker for early intraepithelial lesion of the uterine cervix in cytology samples. Seventy-four cases with abnormal cytology suggesting the existence of cervical intraepithelial neoplasia (CIN) lesions, whose findings were histologically confirmed, were selected; they consisted of 20 CIN1, 21 CIN2, and 33 CIN3, respectively. In addition, 17 normal cases, whose cervical cytology revealed no abnormality over three occasions, were selected. Liquid-based cytology specimens were applied for human papillomavirus (HPV) DNA typing and immunocytochemistry using three different antibodies for p16(INK4a), Ki-67 and PIK3CA, respectively. The fraction of immunopositive cells on the slides was calculated and expressed as mean numbers. Receiver operating characteristic (ROC) plots were generated to determine the diagnostic accuracy of each immunocytochemistry test. The mean number of immunopositive cells in the CIN3 group was significantly higher than other groups for all three antibodies. Among all groups, PIK3CA showed a superior specificity to distinguish CIN3 from other groups. Comparison of three markers by ROC curves also revealed that PIK3CA provided the best method for distinguishing CIN3. Thus, expression of PIK3CA was observed in liquid-based cytology in CIN lesions, which suggested its diagnostic significance in addition to the use of routine cervical cancer smear and the HPV screening program.

Gene expression profiles with cDNA microarray reveal RhoGDI as a predictive marker for paclitaxel resistance in ovarian cancers.

In the current study, we identified paclitaxel-resistant related genes by comparing gene expression profiles of paclitaxel-resistant and parent ovarian cancer cell lines. Gene expression profiles of the human ovarian cancer cell line (KF28), cisplatin-resistant cell line (KFr13) induced from KF28, and paclitaxel-resistant cell lines (KF28TX and KFr13TX) induced by exposing KF28 and KFr13 to dose-escalating paclitaxel were compared and analyzed using cDNA microarray. Of 557 human cancer-related cDNA transcripts compared, 5 genes were found to be underexpressed and 5 genes overexpressed in the paclitaxel-resistant KF28TX, while another paclitaxel-resistant KFr13TX had 5 underexpressed and 8 overexpressed genes. Among these genes, overexpression of the ATP-binding cassette subfamily (MDR-1), Rho guanine dinucleotide phosphate dissociation inhibitor beta (RhoGDI) and insulin-like growth factor binding protein 3 (IGFBP-3) was observed in both paclitaxel-resistant cell lines. Using real-time quantitative PCR, we confirmed the array results. We therefore conclude that IGFBP-3, RhoGDI and MDR-1 were correlated with paclitaxel resistance. Moreover, immunohistochemical staining was analyzed in 22 serous ovarian cancer tissues from patients who received paclitaxel-based chemotherapy, and RhoGDI overexpression was observed more frequently in non-responsers than in responders (p=0.004). RhoGDI expression proved to be a predictive marker of paclitaxel resistance not only in paclitaxel-resistant cell lines, but also in clinical samples.

Adjuvant chemotherapy with irinotecan hydrochloride and cisplatin for clear cell carcinoma of the ovary.

Clear cell carcinoma (CCC) of the ovary has distinct characteristics showing resistance to conventional platinum-based regimen. Our aim was to evaluate the effects of combination therapy with irinotecan hydrochloride and cisplatin (CPT-P), comparing to regimen with paclitaxel and platinum (TP). We retrospective reviewed 172 patients with complete surgical staging procedures including lymphadenenctomy. Forty-six patients received CPT-P and 126 patients were treated with TP. Survival of the two groups was compared. Between CPT-P group and TP group, there was no significant difference in median age, performance status, FIGO stage, rate of optimal cytoreduction, and follow-up period. There was no significant difference in progression-free survival of patients with stage I tumors (p=0.95) and suboptimally debulked stage II-IV tumors (p=0.92). Although there was no significant difference of overall survival, progression-free survival of CPT-P group was significantly better than that of TP group in optimally debulked stage II-IV (p=0.03). Multiple regression survival analysis revealed CPT-P regimen (p=0.02) and residual tumor diameter (p<0.01) were both independent prognostic factors in stage II-IV tumors. The combination of CPT-P was shown to have a potential therapeutic benefit for advanced CCC of the ovary, especially for cases with optimal debulking surgery. However, this is a limited retrospective study, therefore we recommend that the CPT-P regimen be evaluated in a larger prospective study.

Survey of human immunodeficiency virus (HIV)-seropositive patients with mycobacterial infection in Japan.

OBJECTIVE: To assess DNA polymorphisms in mycobacterial isolates obtained from human immunodeficiency virus (HIV)-seropositive patients with tuberculosis in Japan from 1996 to 2003. METHODS: Restriction fragment length polymorphisms (RFLP) from Mycobacterium tuberculosis and Mycobacterium avium isolates obtained from individual seropositive patients with tuberculosis (n=78) were analysed with the use of IS6110 and (CGG)(5) or IS1245 and IS1311, respectively, as markers. As a control, the same procedures were applied to isolates from HIV-seronegative tuberculosis patients (n=87). RESULTS: Of 86 mycobacterial strains, M. tuberculosis, M. avium and Mycobacterium chelonae were identified in 48 (55.8%), 36 (41.9%) and 2 (2.3%) isolates, respectively. The obtained RFLP patterns of M. tuberculosis isolates from both the HIV-seropositive and -seronegative groups were variable, suggesting no obvious clustering among the isolates. Similar results were obtained in isolates of M. avium. CONCLUSIONS: This is the first report on the molecular epidemiology of Mycobacterium spp. isolated from HIV-seropositive patients in Japan. The results indicate that no particular clones of M. tuberculosis or M. avium prevail in HIV-seropositive patients in Japan. Further monitoring of mycobacterial infection associated with HIV infection in Japan should be continued.

Multidrug-resistant Pseudomonas aeruginosa strain that caused an outbreak in a neurosurgery ward and its aac(6')-Iae gene cassette encoding a novel aminoglycoside acetyltransferase.

We characterized multidrug-resistant Pseudomonas aeruginosa strains isolated from patients involved in an outbreak of catheter-associated urinary tract infections that occurred in a neurosurgery ward of a hospital in Sendai, Japan. Pulsed-field gel electrophoresis of SpeI-, XbaI-, or HpaI-digested genomic DNAs from the isolates revealed that clonal expansion of a P. aeruginosa strain designated IMCJ2.S1 had occurred in the ward. This strain possessed broad-spectrum resistance to aminoglycosides, beta-lactams, fluoroquinolones, tetracyclines, sulfonamides, and chlorhexidine. Strain IMCJ2.S1 showed a level of resistance to some kinds of disinfectants similar to that of a control strain of P. aeruginosa, ATCC 27853. IMCJ2.S1 contained a novel class 1 integron, In113, in the chromosome but not on a plasmid. In113 contains an array of three gene cassettes of bla(IMP-1), a novel aminoglycoside resistance gene, and the aadA1 gene. The aminoglycoside resistance gene, designated aac(6')-Iae, encoded a 183-amino-acid protein that shared 57.1% identity with AAC(6')-Iq. Recombinant AAC(6')-Iae protein showed aminoglycoside 6'-N-acetyltransferase activity by thin-layer chromatography. Escherichia coli expressing exogenous aac(6')-Iae showed resistance to amikacin, dibekacin, isepamicin, kanamycin, netilmicin, sisomicin, and tobramycin but not to arbekacin, gentamicins, or streptomycin. Alterations of gyrA and parC at the amino acid sequence level were detected in IMCJ2.S1, suggesting that such mutations confer the resistance to fluoroquinolones observed for this strain. These results indicate that P. aeruginosa IMCJ2.S1 has developed multidrug resistance by acquiring resistance determinants, including a novel member of the aac(6')-I family and mutations in drug resistance genes.

Application of expression genomics for predicting treatment response in cancer.

During tumor progression, multiple genetic changes in the genome vastly alter the transcriptomes of cancers. Some of these changes, including the mutations of various growth regulatory genes as well as alterations in the transcription of a large number of genes, may lead to resistance to treatment. Therefore, capturing such genomic information of the tumors would enable a physician to decide on the course of treatment options clinically available. Currently, it is still not feasible to identify all the genetic mutations that have occurred in a patient's cancer genome. However, the advent of DNA microarray coupled with the completion of the human genome sequence and the identification of all its genes, have made possible genome-wide gene expression profiling of the cancer genome. In this review, we will focus on the application of expression genomics for identifying signature gene expression profiles in primary cancers to predict response to either radio- or chemotherapy. We envision that transcription profiling of the cancer genomes ultimately will not only reveal how altered gene expression results in resistance to treatment, but also be exploited for predicting and personalizing cancer therapy.

Cerebral edema on MRI in severe preeclamptic women developing eclampsia.

OBJECTIVE: The aim of this study is to identify suitable applications for cerebral MR (magnetic resonance) scanning in cases of severe preeclampsia and eclampsia through comparison of clinical course and easily accessible parameters. METHODS: From January 2001 to December 2003, cerebral MR scans were performed on 43 women with severe preeclampsia; of those 41 were enrolled in data analyses. Twenty clinical parameters, including age, body mass index, blood pressure, liver and renal function, and coagulation status, were compared for each patient. Data were analyzed using the SPSS program on a VAX main frame. RESULTS: Among 41 severe preeclamptic women, abnormal MR images were observed in 11 cases including six with systemic seizures. Predictive accuracy of eclampsia with abnormal cerebral MR imaging was 84.9% (P=0.00001), while only 14.3% of severe preeclampsia cases had been diagnosed radiologically. Statistical analysis suggests diastolic BP and serum AST as predictive parameters for abnormal MR images with 82.9% predictive accuracy (P=0.0007). CONCLUSIONS: Cerebral edema can be observed in preeclamptic patients developing eclampsia. Rapid delivery is indicated when diastolic BP and AST are elevated. MR scanning is useful when delivery is delayed due to fetal immaturityin cases of severe preeclampsia.

Treatment options in the management of ovarian cancer.

The standard regimen used as primary chemotherapy of ovarian cancer is combination chemotherapy using paclitaxel and carboplatin. The main objective of first-line chemotherapy is to induce complete response. Although most cases respond to the initial chemotherapy, many cases relapse within 3 years. Such relapsed and persistent cases become resistant to first-line chemotherapy and require second-line chemotherapy. Objectives of such a second-line chemotherapy are to obtain disease palliation to cease disease progression. Meanwhile, consolidation or maintenance chemotherapy may be added to prevent or inhibit disease relapse for patients with advanced disease after induction of complete remission by a primary chemotherapy. When the unresectable tumour is presumed by primary surgery, neoadjuvant chemotherapy may be selected. Recently, conventional cytotoxic anticancer drugs containing paclitaxel have been shown to be capable of inhibiting angiogenesis. The notion of 'redefining' chemotherapeutic drugs has been recognised; thus, continuous low-dose chemotherapy -- so-called metronomic chemotherapy -- has been approved as a new concept. Many new molecular-targeted therapies became available for clinical cancer therapy. The explosion of new molecular targets and the development and application of many powerful technologies should accelerate the discovery of innovative molecular therapeutics. Understanding the molecular mechanisms will help to clarify the pathways in ovarian cancer development and help to identify new therapeutic and diagnostic targets. These are exciting times for new drug development and the treatment of cancer. Cautious optimism should prevail for all investigators involved in translating these exciting new biological findings into new pharmacological agents for treatment of cancer.

Extracellular cAMP-dependent protein kinase (ECPKA) in melanoma.

Melanoma is one of the fastest rising malignancies in the United States. When detected early, primary melanomas are curable through surgery. However, despite significant improvements in diagnosis and surgical, local and systemic therapy, mortality rate in metastatic melanoma remains high. Furthermore, genetic alterations associated with the development and stepwise progression of melanoma, are still unclear. Previous reports show that the catalytic kinase subunit of the cAMP-dependent protein kinase is secreted by tumor cells and can be detected in the serum of cancer patients. We examine in this report the clinical significance of this secreted C subunit kinase termed extracellular protein kinase (ECPKA) in melanoma patients. Our results showed the presence of ECPKA activity in the serum of melanoma patients and correlate with the appearance and size of the tumor. Most importantly, surgical removal of melanoma causes a precipitous decrease in ECPKA activity in the sera of patients, suggesting that ECPKA may be a novel predictive marker in melanoma.

The effect of single weekly paclitaxel in heavily pretreated patients with recurrent or persistent advanced ovarian cancer.

OBJECTIVES: We have reported that single weekly paclitaxel has moderate activity in heavily pretreated ovarian cancer patients and is associated with a favorable toxicity profile. The purpose of this study was to reconfirm the effect of weekly paclitaxel in more number of cases. METHODS: Although 39 patients were enrolled, 37 patients with recurrent or persistent ovarian cancer previously treated with between one and three chemotherapeutic regimens containing platinum were eligible. Patients had measurable or assessable disease defined by clinical exam, radiographic studies, or serum CA 125. One cycle of treatment consisted of paclitaxel 80 mg/m2/week in 1-h infusion, 3 weeks on, 1 week off, and repeated at least twice. Two patients were withdrawn because of refusal of further treatment for neuropathy after the first cycle. Clinical responses were defined by established criteria. RESULTS: Thirty-seven patients were included in this intent-to-treat study. The overall clinical response rate was 45.9% (5 complete responses, 12 partial responses). The clinical response rate in patients with measurable tumor was 25.0% (2 complete responses, 1 partial response), while that in patients without measurable tumor and with assessable CA 125 levels was 56.0% (3 complete responses, 11 partial responses). Clinical response rate in patients with chemotherapy-free interval more than 6 months had about twice higher than that in patients with chemotherapy-free interval less than 6 months. The clinical response rate by number of prior regimens revealed that as number of prior regimens increases, the response rate decreases. CONCLUSION: Weekly paclitaxel has significant antitumor activity in heavily pretreated patients with recurrent or persistent ovarian carcinoma and warrants as second or third line chemotherapy in such setting.

Chronic administration of single weekly paclitaxel in heavily pretreated ovarian cancer patients.

Ovarian cancer patients with paclitaxel-resistance have been reported to respond to a weekly schedule of the same drug. In this report, two cases with long progression free interval by weekly paclitaxel (T) are presented. Case 1. A 41-year-old Japanese woman, gravida 2, para 0, was referred to our hospital in September 16, 1998, because of abdominal mass accompanying large amount of ascites with elevated CA125 (8400 U/ml) and CA19-9 (770 U/ml). Exploratory laparotomy (tumor biopsy plus partial omentectomy) was performed September 21, 1998. After the surgery, the tumor was diagnosed as serous cystadenocarcinoma of the ovary (stage IV) and 6 cycles of treatment consisting of cyclophosphamide, adriamycin and cisplatin (CAP) were performed. The CA 125 level (8400 U/ml) rapidly declined to 150 U/ml by this CAP therapy. After second cytoreductive surgery (SRS) (total hysterectomy and bilateral salpingo-oophorectomy), residual tumor was less than 2 cm. Although 7 cycles of CAP was added, ascites and elevation of CA 125 (5100 U/ml) were observed. Therefore, treatment with single weekly T was performed and CA 125 levels remained between 70-90 U/ml during 13 cycles of this therapy (progression free interval; more than 1 year). Thereafter, she is alive with disease and followed-up. Case 2. A 48-year-old Japanese woman, gravida 3, para 2, was referred to our hospital in July 22, 1998, because of abdominal swelling and pain. Computing tomography (CT) and magnetic resonance imaging (MRI) revealed large amount of ascite and pelvic mass (9 x 7 x 7 cm), and low density area (3 x 3 cm) suggesting metastasis in right lobe of liver. Serum CA 125 level elevated to 5100 U/ml. Bilateral salpingo-oophorectomy and infracolic omentectomy were performed on August 5, 1998. The tumor was diagnosed as endometrioid adenocarcinoma of the ovary, stage IV and chemotherapy with CAP was initiated on September 5, 1998. After 6 cycles of CAP, SRS was performed. After SRS, 3 cycles of CAP were added and changed to weekly T because of damage of renal function. The CA 125 level returned within normal range during weekly T. Total 13 cycles of weekly T were performed and progression free interval was about 18 months. Thereafter, she received treatments with gamma knife and CAP for brain metastasis. She is alive without disease and followed-up. Side effects by weekly T were mild and tolerable despite of long term treatment. In addition, weekly T can be safely used in outpatient setting and even in patients with poor performance status (PS), and warrant long time to progression.
