We report here a summary of the present state of knowledge on the role of lifestyle patterns, suchas physical activity, diet, smoking, hormone therapy, and experience of psychological stress in the modulation ofbreast cancer in women, and discuss commonly accepted biological mechanisms hypothesized as responsible forthe associations. The findings indicate that regular physical activity of moderate to vigorous intensity is probablylinked with the decreased breast cancer risk among postmenopausal females and suggestive for a decrease of therisk in premenopausal women. In contrast, the consumption of high-fat diet, alcohol intake, and use of combinedestrogen and synthetic progestagen hormonal therapy may increase the risk.

The majority of TNBCs show the expression of basal markers on gene expression profiling andmost authors accept TNBC as basal-like (BL) breast cancer. However, a smaller fraction lacks a BL phenotypedespite being TNBC. The literature is silent on non-basal-like (NBL) type of TNBC. The present study wasaimed at defining behavioral differences between BL and NBL phenotypes. Objectives: i) Identify the TNBCsand categorize them into BL and NBL breast cancer. ii) Examine the behavioral differences between twosubtypes. iii) Observe the pattern of treatment failure among TNBCs. Materials and Methods: All TNBC casesduring January 2009-December 2010 were retrieved. The subjects fitting the inclusion criteria of study weredifferentiated into BL and NBL phenotypes using surrogate immunohistochemistry with three basal markers34βE12, c-Kit and EGFR as per the algorithm defined by Nielsen et al. The detailed data of subjects werecollated from clinical records. The comparison of clinicopathological features between two subgroups was doneusing statistical analyses. The pattern of treatment failure along with its association with prognostic factorswas assessed. Results: TNBC constituted 18% of breast cancer cases considered in the study. The BL and NBLsubtypes accounted for 81% and 19% respectively of the TNBC group. No statistically significant associationwas seen between prognostic parameters and two phenotypes. Among patients with treatment failure, 19% werewith BL and 15% were with NBL phenotype. The mean disease free survival (DFS) in groups BL and NBL was30.0 and 37.9 months respectively, while mean overall survival (OS) was 31.93 and 38.5 months respectively.Treatment failure was significantly associated with stage (p=.023) among prognostic factors. Conclusions: Diseasestage at presentation is an important prognostic factor influencing the treatment failure and survival amongTNBCs. Increasing tumor size is related to lymph node positivity. BL tumors have a more aggressive clinicalcourse than that of NBL as shown by shorter DFS and OS, despite having no statistically significant differencebetween prognostic parameters.

Real time PCRand immunofluorescence staining for MRP1 revealed a high silent efficiency of these two shRNAs. Functionally,shRNA-expressing cells showed increased rhodamine 123 retention in A549/DDP cells, indicating reduced effluxability of tumor cells in the absence of MRP1.

Materials and Methods:Eighty-one patients with gastric cancer who had undergone radical gastrectomy and were found to have lymphnode metastasis upon pathological examination were included. Histopathological samples were obtained frombiopsies obtained during patient gastrectomies and lymph node dissection.

Results: Sixty-four (79%) patients wereSISH (-), while 17 (21%) were SISH (+) in the primary tumor. However, in metastatic lymph nodes, HER2 statuswas SISH positive in 5 (28.3%) of the 64 SISH (-) primary tumor specimens. One of the 17 SISH (+) primarytumors was SISH (-) in the metastatic lymph nodes. Thus, SISH results for HER2 in both primary tumors andlymph node metastases were comparable, showing a concordance of 92.5%.

However, the mode of its action remainsunclear. Therefore, in this study, we aimed to elucidate the antitumor mechanism of rapamycin, hypotheticallyvia apoptotic promotion, using MCF-7 breast cancer cells. Materials and Methods: MCF-7 cells were platedat a density of 15105 cells/well in 6-well plates. After 24h, cells were treated with a series of concentrations ofrapamycin while only adding DMEM medium with PEG for the control regiment and grown at 37oC, 5% CO2and 95% air for 72h. Trypan blue was used to determine the cell viability and proliferation. Untreated andrapamycin-treated MCF-7 cells were also examined for morphological changes with an inverted-phase contrastmicroscope. Alteration in cell morphology was ascertained, along with a stage in the cell cycle and proliferation.In addition, cytotoxicity testing was performed using normal mouse breast mammary pads. Results: Our resultsclearly showed that rapamycin exhibited inhibitory activity on MCF-7 cell lines. The IC50 value of rapamycin onthe MCF-7 cells was determined as 0.4μg/ml (p<0.05). Direct observation by inverted microscopy demonstratedthat the MCF-7 cells treated with rapamycin showed characteristic features of apoptosis including cell shrinkage,vascularization and autophagy. Cells underwent early apoptosis up to 24% after 72h. Analysis of the cell cycleshowed an increase in the G0G1 phase cell population and a corresponding decrease in the S and G2M phasepopulations, from 81.5% to 91.3% and 17.3% to 7.9%, respectively. Conclusions: This study demonstrated thatrapamycin may potentially act as an anti-cancer agent via the inhibition of growth with some morphologicalchanges of the MCF-7 cancer cells, arrest cell cycle progression at G0/G1 phase and induction of apoptosis inlate stage of apoptosis.

Eight of nine metastatic patients had a pathologic Gleason score(GS) 9 and developed bone metastasis, while the remaining one had pathologic GS 7 and developed metastasisonly to para-aortic lymph nodes. On multivariate analyses, pathologic GS ≥9 and regional lymph node metastasis(pN1) were independent predictors of clinical metastasis and pathologic GS ≥9 was an independent predictor ofcancer-specific death. Conclusions: Pathologic GS ≥9 and pN1 were independent predictors of clinical metastasisin post-prostatectomy patients who received immediate adjuvant ADT. Furthermore, pathologic GS ≥9 was anindispensable condition for bone metastasis, which may imply that patients with GS ≤8 on adjuvant ADT areunlikely to develop bone metastasis.}, keywords = {adjuvant,Androgen deprivation therapy,clinical metastasis,Prostate Cancer,radical prostatectomy}, url = {https://journal.waocp.org/article_30342.html}, eprint = {https://journal.waocp.org/article_30342_38349e710e70c842631d2816dd3f3d9a.pdf} } @article { author = {}, title = {Descriptive Epidemiology of Common Female Cancers in the North East India - a Hospital Based Study}, journal = {Asian Pacific Journal of Cancer Prevention}, volume = {15}, number = {24}, pages = {10735-10738}, year = {2014}, publisher = {West Asia Organization for Cancer Prevention (WAOCP), APOCP's West Asia Chapter.}, issn = {1513-7368}, eissn = {2476-762X}, doi = {}, abstract = {Background: Cancers of the breast, uterine cervix and ovary are common cancers amongst females ofNorth East India.

The aim of this study was to investigate clinical correlations of the CYP2C19 genotype in patients withgastritis, peptic ulcer disease (PUD), peptic ulcer bleeding (PUB) and gastric cancer in Thailand. Materialsand Methods: Clinical information, endoscopic findings and H. pylori infection status of patients were assessedbetween May 2012 and November 2014 in Thammasat University Hospital, Thailand. Upper GI endoscopy wasperformed for all patients. Five milliliters of blood were collected for H. pylori serological diagnosis and CYP2C19study. CYP2C19 genotypes were determined by polymerase chain reaction (PCR) and restriction fragment lengthpolymorphism analysis (RFLP) and classified as rapid metabolizer (RM), intermediate metabolizer (IM) or poormetabolizer (PM). Results: A total of 202 patients were enrolled including 114 with gastritis, 36 with PUD, 50 withPUB and 2 with gastric cancer. Prevalence of CYP2C19 genotype was 82/202 (40.6%) in RM, 99/202 (49%) inIM and 21/202 (10.4%) in PM. Overall H. pylori infection was 138/202 patients (68.3%). H. pylori infection wasdemonstrated in 72% in RM genotype, 69.7% in IM genotype and 47.6% in PM genotype. Both gastric cancerpatients had the IM genotype. In PUB patients, the prevalence of genotype RM (56%) was highest followed byIM (32%) and PM(12%). Furthermore, the prevalence of genotype RM in PUB was significantly greater thangastritis patients (56% vs 36%: p=0.016; OR=2.3, 95%CI=1.1-4.7). Conclusions: CYP2C19 genotype IM was themost common genotype whereas genotype RM was the most common in PUB patients. All gastric cancer patientshad genotype IM.

Approximately 10-20% of womenwith minor cytologic abnormalities have histologic high-grade squamous intraepithelial or worse lesions (HSIL+).In Thailand, women with minor cytologic abnormalities have a relatively high risk of cervical cancer, and referralfor colposcopy has been suggested. A triage test is useful in the selection of women at risk for histologic HSIL+ toreduce the colposcopy burden. The aim of this study was to assess the performance of high-risk HPV DNA test intriage of women with minor cytologic abnormalities in northern Thailand. Materials and Methods: All womenwith ASC-US/LSIL cytology who were referred to our colposcopy clinic from October 2010 to February 2014were included. HPV DNA testing was performed using Hybrid Capture 2 (HC2). All patients received colposcopicexamination. Accuracy values of HC2 in predicting the presence of histologic HSIL+ were calculated. Results:There were 238 women in this study (121 ASC-US and 117 LSIL). The HC2 positivity rate was significantlyhigher in the LSIL group than in ASC-US group (74.8% versus 41.0%, p<0.001). Histologic HSIL+ was detectedin 9 women (7.4%) in the ASC-US group and 16 women (13.7%) in the LSIL group (p=0.141). There was nohistologic HSIL+ detected among HC2-negative cases (sensitivity and negative predictive value of 100%). Theperformance of HC2 triage was highest among women aged >50 years with ASC-US cytology. An increase in thecut-off threshold for positive HC2 resulted in a substantial decrease of sensitivity and negative predictive value.Conclusions: HPV DNA testing with HC2 shows very high sensitivity and negative predictive value in triage ofwomen with minor cervical cytologic abnormalities in northern Thailand.
