    Once a widely accepted notion, mammography screening is now called into doubt, in some cases rendered unjustifiable, by studies in developed countries. In spite of the fact that screening cannot prove to be effective may seem meaningless at the first glance, in practice, the procedures and strategies are to be reconstructed. In Iran, for instance, 40% of diagnosed breast cancer in women are locally developed or metastatic. The main issues for screening such cancers are primary tumor size, axillary nodal status down staging strategy, and screening programs. In fact, by cancer early detection we will be needless of the high technology of the developed world, while we lack the infrastructure and resources to use the technology appropriately to achieve adequate coverage of the population.
    In our previous studies, we found that tumor size and nodal status are the most frequent symptoms for referring to clinics, also we concluded that screening mammography in many countries would not be beneficial.
    Although effective in the first round for detection of about 53% of the cancer cases, provided the equipment is readily available throughout the country, it is far less efficient in the second and third rounds which spells an ineffective strategy. Therefore, a shift in strategies seems essential for health decision makers especially in countries including Iran.

    Context: Cutaneous head and neck melanoma is a challenging disease owing to its aggressive nature and often times advanced stage at presentation. Age, sex, and subsite are three prognostic indicators which can be determined prior to treatment or testing, and can allow the practitioner to counsel the patient before initiating therapy.
    Evidence Acquisition: A PubMed search was conducted utilizing various terms relating to the subject matter. Articles over the past 25 years were analyzed and appropriately selected for review.
    Results
    It appears that patients older than 65 have a decreased overall 5 year survival compared to their younger counterparts. Male patients have poorer prognosis compared to female patients as noted by the decreased overall survival, decreased disease specific survival, and shorter time to distant metastasis. Scalp subsite was most uniformly accepted as having the worst prognosis in the head and neck, and may even serve as an independent prognostic indicator.
    Conclusions
    Advanced age, male sex, and scalp subsite all portend poor prognosis in patients with cutaneous head and neck melanoma.

    Context: Breast cancer has been considered as one of the most common types of cancer among the women worldwide, and patients with breast neoplasms have been reported with high prevalence of low serum 25-hydroxyvitamin D levels.
    Objectives
    Our aim was to evaluate the correlation of plasma 25-hydroxyvitamin D deficiency with breast neoplasms risk among women.
    Data Sources: PubMed database was searched with MeSH (medical subject headings) keywords «vitamin D AND breast neoplasms» which was restricted by original articles written only in English and published from January 1, 2014.
    Study Selection: To find the articles that met eligibility criteria, titles and abstracts were examined.
    Data Extraction: This systematic review was conducted according to PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement. Critical appraising of evidence was performed, using the study quality assessment tools of national institutes of health, national heart, lung and blood institute (NHLBI).
    Results
    Overall, 76 potential articles were identified and after screening, 13 articles met eligible criteria for inclusion. Definition of low vitamin D levels varied greatly among studies, making comparisons difficult, but most of them have defined deficiency as 25 (OH) D
    Conclusions
    This study has provided evidence that vitamin D deficiency has been very prevalent in patients with breast neoplasms, more than comparable matched control population, and risk of breast cancer has increased with low vitamin D levels, suggesting the need for high quality studies that assessed the health consequences attributable to vitamin D deficiency employing standard definitions.

    Background
    Colorectal cancer (CRC) is the second most commonly diagnosed cancer and the fourth leading cause of cancer-related mortality around the world.
    Objectives
    With regard to the role of obesity in colorectal cancer (CRC) and the role of leptin in obesity, we investigated whether leptin (LEP) and leptin receptor (LEPR) gene variants are associated with CRC risk.
    Patients and
    Methods
    We evaluated LEP (rs7799039) and LEPR (rs1137101) gene variants by using PCR-RFLP method in 261 cases with CRC and 339 controls.
    Results
    No significant difference was found for rs7799039 and rs1137101gene variants between the cases with CRC and controls. However, the LEPR rs1137101 “GG” genotype compared with “AA” genotype and “AA AG” genotype was associated with increased risks for obesity, and the differences remained significant after adjustment for confounding factors including age, sex, smoking status, and NSAID use (P = 0.015; OR = 2.42, 95%CI = 1.19 - 4.93 and P = 0.016; OR = 2.28, 95%CI = 1.17 - 4.48, respectively). In addition, the LEPR “G” allele compared with the “A” allele was associated with an increased risk for obesity (P = 0.024; OR = 1.44, 95%CI = 1.05 - 1.98).
    Conclusions
    Consistent with most previous studies, our findings found no association between LEP (rs7799039) and LEPR (rs1137101) gene variants and CRC risk. However, the LEPR rs1137101 “GG” genotype compared with the “AA” genotype and “AA” genotype was associated with a 2.42-fold and a 2.28-fold increased risk for obesity, respectively.

    Background
    Radiotherapy is the gold standard for treatment of prostrate cancer as it can cover an adequate area of tissues at risk for metastasis.
    Objectives
    We evaluated the Pelvic lymph node coverage of conventional radiotherapy fields based on bone and vessels landmarks using computed tomography (CT) simulation in patients with prostate cancer referred to Shohada-e-Tajrish hospital.
    Patients and
    Methods
    In this cross sectional study, 40 patients with prostate cancer at the Stage T1c to T3b were studied. Pelvic lymph nodes were contoured by using pelvic vessels as surrogate markers. The distances were measured at different points of anterior-posterior (AP) and lateral fields and distances > 5 mm or more between the contoured nodes and the field borders.
    Results
    Mean and standard deviation of the aortic bifurcation from the superior border was 4.73 ± 1.16 cm, the distance of common iliac bifurcation from the superior border was 1.11 ± 1.25 cm, the mean (SD) distance of right external iliac from the lateral border of AP field was 2.06 ± 0.48 cm and for left external iliac artery was 1.90 ± 0.56 cm. The distance of the external iliac artery from the anterior border of the lateral field was 2.30 ± 0.74 cm. The distance of the external iliac artery from pelvic rim was 0.59 ± 0.59 cm, distance of bifurcation of iliac from sacroiliac joint was 0.82 ± 1.01 cm, the size of the pelvic rim was 12.30 ± 0.64 cm, sacral width was 8.29 ± 1.01 cm, anterior promontory symphysis distance was 12.02 ± 0.92 cm and posterior promontory symphysis distance was 10.98 ± 0.73 cm.
    Conclusions
    We observed that conventional radiotherapy using CT simulation based on bone and vessels landmarks provided adequate coverage of pelvic lymph nodes in our patients with prostate cancer.

    Background
    Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity. A relationship between the human papilloma virus (HPV) infection and the prognosis of oral cavity SCC (OCSCC) has been discussed before.
    Objectives
    We investigated the prevalence rate of HPV status in patients with OCSCC, and its effects on clinicopathological characteristics of tumors and patients’ prognosis.
    Patients and
    Methods
    Sections of formalin-fixed, paraffin-embedded tissue blocks from 114 histopathologically confirmed OCSCC cases were investigated in this study. Polymerase chain reaction (PCR) was applied to evaluate the HPV status in the samples.
    Results
    Fifteen (13.16%) cases were identified as HPV positive. The detected viral subtypes in this study were the subtypes 6 and 11. The stage and especially lymph node stage was significantly higher in the HPV positive group compared to the HPV negative group (P = 0.04). Disease free survival (DFS) was remarkably lower in the HPV positive group compared to the HPV negative group (13.9 vs. 49.9 months, P = 0.02). Overall survival (OS) was also significantly inferior in the HPV positive group (15.7 vs. 49.6 months, P = 0.01). In the current study, no significant differences were observed between two groups in relation to the variables of age, gender, tumors site, tumor size, tumor grading and also the recurrence rate.
    Conclusions
    The observed higher mortality rate among the HPV positive group indicates the poorer prognosis of this group in comparison with the HPV negative patients. The incidence rate of HPV infection was low in the studied samples; however, interaction of subtypes 6 and 11 of HPV in poorer prognosis of the patients and a carcinogenic role of HPV in OCSCC cannot be ruled out.

    Background
    B cell chronic lymphocytic leukemia is one of the most frequent hematologic malignancies in the world. Cellular surface CD markers and serum Beta-2-microglobulin may be used as a prognostic tool in CLL patients.
    Objectives
    In the present study we introduce serum adenosine deaminase as a diagnostic marker in CLL.
    Materials And Methods
    Blood samples were collected from B-CLL and healthy subjects. White blood cell, red blood cell and platelet count and blood Erythrocyte sedimentation rate was recorded and serum Beta-2-microglobulin, Lactate dehydrogenase and total ADA enzyme activity were determined.
    Results
    Serum ADA activity was significantly higher in patients group than that of controls. ADA had a significant and direct correlation with B2M, WBC, LDH and ESR. However, there was not any relation between ADA and the stages of disease. Diagnostic cut-off, sensitivity and specificity of the serum ADA test were 27.97 U/L, 91% and 94%, respectively.
    Conclusions
    A higher ADA activity in patients group and its correlation with CLL markers were seen in our study. High diagnostic value of serum ADA in our study suggests that it might be considered as a useful screening tool among the other markers in CLL.

    Background
    Finding a tumor marker to predict the aggressive behavior of molar pregnancy in early stages has yet been a topic for studies.
    Objectives
    In this survey we planned to study patients with molar pregnancy to 1) assess the p53 and c-erbB-2 expression in trophoblastic tissue, 2) to study the relationship between their expression intensity and progression of a molar pregnancy to gestational trophoblastic neoplasia, and 3) to determine a cut off value for the amount of p53 and c-erbB-2 expression which might correlate with aggressive behavior of molar pregnancy.
    Patients and
    Methods
    In a prospective cross sectional study by using a high accuracy technique EnVision Tm system for immunohistochemistry staining of molar pregnancy samples, we evaluated p53 and c-erbB-2 expression in cytotrophoblast and syncytiotrophoblast and the correlation of their expression with progression of molar pregnancy to gestational trophoblastic neoplasia (GTN). Normal prostatic tissue and Breast cancer tissue were used as positive controls.
    Results
    We studied 28 patients with simple molar pregnancy (SMP) and 30 with GTN. Cytotrophobalst had significantly higher expression of p53 and c-erbB-2 and syncytiotrophoblast had greater expression of p53 in GTN group as compared to SMP group. The cut off values for percentage of p53 positive immunostained cytotrophoblast and syncytiotrophoblast were 5.5% and 2.5%. In c-erbB-2 positive membranous stained cytotrophoblast the cut off was 12.5%.
    Conclusions
    Our data suggests that over expression of p53 and c-erbB-2 is associated with malignant progression of molar pregnancy. We encountered that high expression of p53 and c-erbB-2 in trophoblastic cells could predict gestational trophoblastic neoplasia during the early stages.

    Background
    Lactobacilli are a group of beneficial bacteria whose anti cancer effects have been evaluated in different cancer cell lines as well as animal models and human subjects. Such anti cancer effects can be exerted via different mechanisms such as modulation of immune response as well as inhibition of pathogens colonization. In addition, lactobacilli have direct cytotoxic effects against cancer cells which may be exerted through modulation of expression cancer related pathways.
    Objectives
    The aim of this study is to find the mechanism of anti cancer effects of two lactobacilli strains, Lactobacillus. crispatus (LC) and Lactobacillus. rhamnosus (LR).
    Materials And Methods
    We analyzed expression of some mTOR and Wnt/ β-catenin pathways genes in three cancer cell lines (HeLa, MDA-MB-231 and HT-29) following treatment with LC and LR culture supernatants.
    Results
    Of note, the expression of CCND1 as a marker of cell proliferation, survival, and angiogenesis, has been decreased following LR treatment in all cell lines. In addition, the expression of SFRP2, an antagonist of Wnt pathway, has been increased in HT-29 following LR treatment and in HeLa cells following LR and LC treatments. Furthermore, we have demonstrated the downregulation of S6K1 expression, a marker of poor prognosis, following LR treatment in HT-29 and following LR and LC treatments in MDA-MB-231 cell line.
    Conclusions
    Consequently, lactobacilli can modulate expression of mTOR and Wnt/ β-catenin pathways genes in cancer cell lines in a strain specific as well as cell type specific manner.

    Background
    Cancer is the third main cause of death in Iran only after cardiovascular diseases and accidents.
    Objectives
    The main aim of this research study was to identify nurses’ understanding of cancer patients’ Quality of Life (QoL) in an Iranian context.
    Patients and
    Methods
    This descriptive correlational study was conducted in an educative referral oncology center affiliated to Isfahan University of Medical Sciences, Isfahan, Iran in 2013. 50 pairs of cancer patients and their nurses were conveniently recruited. The sample of nurses were selected based on consensus sampling which included more than 70 percent of eligible nurses in the hospital. Patients and nurses were requested to complete the Farsi version of the world health organization quality of life (WHOQoL-BREF) questionnaire, separately. QoL was measured across four dimensions including physical, psychological, social relationship and environmental.
    Results
    The QoL mean domain scores of patients were 10.06, 11.88, 12.76 and 11.96, respectively. The corresponding scores of nurses were 11.6, 11.23, 12.65 and 12.07. Pearson correlations between patients and nurses scores were 0.42, 0.5, 0.25 and 0.58 which revealed a fair to moderate agreement between nurses’ and patients’ scores in different domains. Paired samples t-test values indicated that physical QoL mean domain scores of patients were significantly lower than the corresponding drawings of nurses [t (49) = -3.41, P
    Conclusions
    The main finding of this QoL study was that nurses generally have a moderate understanding of cancer patients’ QoL. Therefore, in order to meet different physio-psycho-social needs of patients, nurses must enhance their understanding of patients’ QoL particularly in more subjective and personal domains like social domain using a holistic approach.

    Introduction
    Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare.
    Case Presentation
    This study has reported a 33-year-old woman presented with abnormal vaginal discharge. Gynecologic examination revealed a cervical mass with grape- like feature protruding into vagina with posterior- superior vaginal wall involvement. Biopsy has performed and pathologic examination was consistent with embryonal botryoid type rhabdomyosarcoma. She has undergone the staging work up measurements including thoracic computed tomography (CT) scan, abdominopelvic magnetic resonance imaging (MRI), bone scan and bone marrow examination. In exception of abdominopelvic MRI, with 2 suspicious pelvic lymph nodes in addition of cervical mass, all others were normal. Radical hysterectomy with lymph node debulking and ovarian preservation has performed. Final results have shown embryonal botryoid type rhabdomyosarcoma of cervix. ovaries, endometrium, parametrium, and follopian tubes were unremarkable. Pelvic lymph nodes pathology and intraabdominal fluid cytology were negative for malignancy. Lymphovascular invasion was identified. She has advised for adjuvant chemotherapy.
    Conclusions
    This case has reminded that embryonal rhabdomyosarcoma could occur in uncommon site and older female. Longer follow up of these cases has required due to lack of survival data for embryonal rhabdomyosarcoma of this site and age group.

    Stevens-Johnson syndrome has been an acute, usually self-limiting disease of the skin and mucous membranes. This case report has presented an evidence of the development Stevens - Johnson syndrome associated with combination chemotherapy administration of 5FU, gemcitabin and cisplatin in a patient with biliary tract cancer. Our case was a 54-year-old woman patient, a case of biliary tract cancer who has developed more severe symptoms of Stevens-Johnson syndrome. Diagnosis has confirmed by skin biopsy of an affected area .The patient has improved with supportive care, and during 25 day occurred recovery. Although Stevens-Johnson syndrome has been a rare toxicity, physicians should pay a special attention to the monitoring of biliary tract cancer patients on combination chemotherapy with 5FU, cisplatin and gemcitabin.
