  • Purpose : Simple hysterectomy is not a standard surgery for invasive cervical carcinoma. This study was performed to investigate the efficacy of radiotherapy following simple hysterectomy in the invasive cervical cancer. Materials and Methods : Retrospective analysis was done for 19 patients with invasive cervical carcinoma who were treated with radiotherapy following simple hysterectomy from April 1989 to December 1993 The median a9e of patients was 47 years old. Patients were treated with external beam radiation therapy alone (17) or external beam radiation therapy plus intra vaginal ovoid irradiation (2). The median follow up period was 46 months. Results : The 4 year overall survival rate was $75\%$. The 4 rear local control rate was $89\%$. Two patients had recurred at the locoregional and distant sites, and another two patients at distant sites. Conclusion : We confirmed that radiotherapy is the adequate treatment modality for patients with invasive cervical cancer who underwent simple hysterectomy.

  • Cutaneous horn is a morphologic designation for a projectile, conical, dense hyperkeratotic nodule that resembles the horn of an animal. The lesion varies in size from only a few millimeters to several centimeters, in color(white or yellowish) and in form (straight, curved, or twisted). It arises from a wide range of epidermal lesions, which include benign lesions, premalignant lesions and malignant lesions. An 83-year-old women came to our clinic with a giant cutaneous horn on the right chin and a small horn on the left upper eyelid. The patient had no palpable cervical lymph node. A wide elliptical skin incision was made and the horn was totally excised. In pathology, the giant cutaneous horn on the right chin revealed a moderately differentiated squamous cell carcinoma with subcutis invasion at its base. "Giant cutaneous horns" have often been associated with invasive squamous cell carcinoma. Cutaneous horns are common lesions usually found on the face, rarely larger than 2 cm. As large cutaneous horns are often associated with underlying malignancy, histopathologic examination of the base of the lesion is necessary to rule out carcinoma and full excision is recommended.

  • Objectives: The goal of this study was to determine the correlation of clinicopathological factors and the up-regulation of vascular endothelial growth factor (VEGF) expression in oral squamous cell carcinoma. Materials and Methods: Immunohistochemical staining of VEGF and quantitative real-time polymerase chain reaction (RT-PCR) of VEGF mRNA were performed in 20 specimens from 20 patients with oral squamous cell carcinoma and another 20 specimens from 20 patients with carcinoma in situ as a controlled group. Results: The results were as follows: 1) In immunohistochemical study of poorly differentiated and invasive oral squamous cell carcinoma, high-level staining of VEGF was observed. Significant correlation was observed between immunohistochemical VEGF expression and histologic differentiation, tumor size of specimens (Pearson correlation analysis, significance r>0.6, P<0.05). 2) In VEGF quantitative RT-PCR analysis, progressive cancer showed more VEGF expression than carcinoma in situ. Paired-samples analysis determined the difference of VEGF mRNA expression level between cancer tissue and carcinoma in situ tissue, between T1 and T2-4 (Student's t-test, P<0.05). Conclusion: These findings suggest that up-regulation of VEGF may play a role in the angiogenesis and progression of oral squamous cell carcinoma.

  • Background and Objectives : Detection of vascular abnormalities in vocal cord (VC) leukoplakia is important for the diagnosis of neoplastic change of the mucosa. The aim of this study was to investigate the value of i-scan in the differential diagnosis of VC leukoplakia based on visualization of abnormal vascular features. Material and Methods : Fifty-two patients with leukoplakia were enrolled in the study. Images of their larynx obtained using conventional white light endoscopy and an i-scan-enhanced endoscopy (Pentax DEFINA EPK-3000 Video Processors, with Pentax VNLJ10) were reviewed. The microvascular features of the lesions and vascular changes were analyzed and the results were compared with the histopathologic diagnosis. Results : Among the 52 leukoplakia patients, 7 (13.5%) patients had squamous hyperplasia, 10 (19.3%) mild dysplasia, 2 (3.8%) moderate dysplasia, 14 (26.9%) severe dysplasia, 4 (7.7%) carcinoma in situ, and 15 (28.8%) invasive squamous cell carcinoma on histopathologic examination. Using i-scan-enhanced endoscopy, abnormal vascular change with neoplastic neoangiogenesis was detected in most cases of malignant VC lesion [severe dysplasia : 9/14 (64.3%), carcinoma in situ: 2/4 (50.0%), and invasive squamous cell carcinoma : 11/15 (73.4%)]. Conclusion : i-scan-enhanced endoscopy is a useful optical technique for the diagnosis of VC leukoplakia. Our results suggest that i-scan may be a promising diagnostic tool in the early detection of laryngeal cancer.

  • Background: Male breast cancer (MBC) is a rare disease that accounts for less than 1% of all cancers in men and less than 1% of all diagnosed breast cancers. In this study, we retrospectively evaluated the clinicopathological features, treatment options and overall survival in Kurdish MBC cases. Materials and Methods: Seventeen MBC were referred to Department of Radiation Oncology in Imam Reza Hospital, Kermanshah, Iran, between 2010 and 2016. Immunohistochemical analysis was performed for ER, PR and Her2 biomarkers and FISH for those with Her2 2+. Median follow-up period was 30 months (2-65 months). We excluded from the study patients who did not have follow-up after initial diagnosis. Treatment methods were chemotherapy, radiotherapy, hormonal therapy, target therapy and palliative care. Survival was estimated by the Kaplan Meier method (Prism 5). Results: The mean age at diagnosis was $49.24{\pm}17$ years (range, 24-85 years). Grade II was the most grade in MBC (65%). Fourteen patients (82%) had invasive ductal carcinoma, one (6%) had ductal carcinoma in situ and 2 (12%) had invasive papillary. ER, PR and Her2 were significantly positive in 14/17, 8/17 and 2/17 cases, respectively. The treatment included modified radical mastectomy for most patients. Chemotherapy with TAC and CEF regimens was delivered to 15/17 cases. Tamoxifen therapy was delivered to 14/17 cases. Three stage IV patients received Avestin and two with Her2 3+ were given Trastuzumab (Herceptin). Patients received adjuvant radiotherapy following surgery and chemotherapy. The site of metastasis was the bone in 2 cases, lung in 1 case and liver in 1 case. Zoledronic acid (Zometa) was prescribed for patients with bone metastasis. Five-year overall survival rate was 64%. Conclusions: MBC is rare. Thus, we need larger studies are in collaboration with several research centers in the field of breast cancer. ER positive, grade II of invasive ductal carcinoma, stage II and right side happened more with MBC. Overall survival is similar to other studies.

  • Purpose: To investigate correlations of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor type 2 (HER2) statuses with magnetic resonance imaging (MRI) features and clinicohistological characteristics in patients with invasive lobular carcinoma (ILC). Materials and Methods: Data from 64 histologically confirmed ILCs were analyzed retrospectively. Preoperative breast MRI was reviewed for morphology and dynamic contrast-enhanced kinetics of the tumor. Pathologic reports were reviewed for ER, PR, and HER2 positivity, tumor size, lymph node metastasis, and the number of metastatic lymph nodes. Furthermore, there was an investigation of the MRI features and clinicohistologic characteristics, according to the ER, PR, and HER2 statuses. Results: A significant difference in MRI features and clinicohistological tumor characteristics were observed only in relation to PR status. Of the 64 ILCs, 10 (15.6%) were PR negative. PR negative cancers, compared with PR positive cancers, were more likely to present as non-mass enhancement (P = 0.027); have a significantly larger mean tumor size ($5.00{\pm}1.05cm$ vs. $2.57{\pm}0.21cm$, P = 0.021); and have significantly more metastatic lymph nodes (P = 0.010). Conclusion: PR negative ILC presented more frequently as non-mass enhancement on MRI, with larger tumors and increased numbers of metastatic lymph nodes. Therefore, the PR status plays an important role in determining MRI features and clinicohistological characteristics of ILC.

  • It's known that having multiple sexual partners is one of the risk factors of human papillomavirus (HPV) infection which is a major cause of cervical cancer. However, it is not clear whether the number of sexual partners is an independent risk factor for cervical cancer. We identified relevant studies by searching the databases of MEDLINE, PubMed and ScienceDirect published in English from January 1980 to January 2014. We analyzed those studies by combining the study-specific odds ratios (ORs) using random-effects models. Forty-one studies were included in this meta-analysis. We observed that the number of sexual partners was associated with the occurrence of non-malignant cervical disease (OR=1.82, 95%CI 1.63-2.00) and invasive cervical carcinoma (OR=1.77, 95%CI 1.50-2.05). Subgroup analyses revealed that the association remained significant after controlling for HPV infection (OR=1.52, 95%CI 1.21-1.83 for non-malignant disease; OR=1.53, 95%CI 1.30-1.76 for invasive cervical carcinoma). We found that there was a non-linear relation of the number of sexual partners with both non-malignant cervical disease and invasive cervical carcinoma. The risk of both malignant and non-malignant disease is relatively stable in women with more than 4-7 sexual partners. Furthermore, the frequency-risk of disease remained significant after controlling for HPV infection.The study suggested that h aving multiple sexual partners, with or without HPV infection, is a potential risk factor of cervical cancer.

  • Background: Bronchioloalveolar carcinoma (BAC) is considered a subtype of adenocarcinoma of the lung. Recently BAC has been variously termed adenocarcinoma in situ, minimally invasive adenocarcinoma, lepidic predominant invasive adenocarcinoma, and invasive mucinous adenocarcinoma. The aim of the study was to analyze and detect prognostic factors of patients with BAC over a 7-year period. Materials and Methods: This retrospective single-center study included 44 patients with BAC. The impact on survival of fifteen variables (gender, age, smoking status, cough, dyspnea, hemoptysis, fever, chest pain, sputum, metastasis number, Karnofsky performance status, pT, pN, TNM stage, cytotoxic chemoterapy) were assessed. Results: Median age was 55 years (38-83). Most patients were male (63.6%) and stage IV (59.1%). Twenty-one patients (47.7%) received cytotoxic chemotherapy (platinum-based regimens) for metastatic disease. Objective response rate was 33.3% (4 partial, 3 complete responses). Stable disease was observed in nine in patients (42.8%). Disease progression was noted in 5 (23.8%). The median OS for all patients was 12 months (95%CI, 2.08-22.9 months). Independent predictors for overall survival were: Karnofsky performance status (HR:3.30, p 0.009), pN (HR:3.81, p 0.018), TNM stage (HR:6.49, p 0.012) and hemoptysis (HR:2.31, p 0.046). Conclusions: Karnofsky performance status, pN, TNM stage and hemoptysis appear to have significant impact on predicting patient survival in cases of BAC.

  • Background: Triple negative breast cancer (TNBC), characterized as estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 Her2 negative and accounting for 10-17% of all breast carcinomas, is only partially responsive to chemotherapy and suffers from a lack of clinically established targeted therapies. The aim of the current study was to evaluate the patterns of treatment and clinicopathology figures in Kurdish patients with triple-negative breast cancer, and to compare these to other reports. Materials and Methods: Between 2001 and 2014, 950 breast cancer patients were referred to our clinic. There were 74 female patients with TNBC, including 70 patients was invasive ductal carcinoma entered into our study. ER and PR positivity was defined as positive immunohistochemical staining in more than 10% of tumor cells. Immunohistochemistry assay with anti-HER2 antibodies was used to identify HER negative (0 and 1+) or positive (2+ and 3+). HER2 gene amplification was determined by fluorescent in situ hybridization (FISH). Overall survival (OS) was plotted with GraphPad Prism 5 Software using Kaplan-Meier and log-rank tests for comparison of results. Results: The mean age in the first diagnosis for 70 patients with triple TNBC and invasive ductal carcinoma was 49.6 years that range of age was 27-82 years. All of the patients were female. Of 70 patients, 23 patients had metastasis. Thirty-two patients (45.7%) were treated with tamoxifen and 39 (55.7%) with radiotherapy. Three-year, 5-year and 10-year OS rates for all patients were 82%, 72% and 64%, respectively. Conclusions: The OS in our West Iran TNBC patients is less than reported elsewhere. However, treatment with combination of tamoxifen plus radiation increases the OS and reduces the mortality rate.

  • Oral squamous cell carcinoma (OSCC), the most common head and neck cancer, shows poor prognosis as a result of frequent local invasion and lymph node metastasis that is mediated by multiple proteolytic enzymes and angiogenesis. In recent reports, angiogenesis is known to play an important role in tumor invasion and metastasis. The purpose of this study was to determine the role of angiogenesis in OSCCs, particularly with respect to the invasive and the metastatic potential. The microvessel density (CD31) in 34 human OSCC cases were investigated by immunohistochemistry, and reviewed with respect to the invasiveness and the presence of lymph node metastasis and following results were obtained. The blood vessel density $(28.8{\pm}7.9)$ in the strong invasive cases were significantly higher than those $(23.3{\pm}6.9)$ in the weak invasive cases. (p<0.05) In the 14 cases with lymph node metastasis, the average blood vessel density was $28.5{\pm}9.6$. On the other hand, in the 20 cases without lymph node metastasis, the blood vessel density was $25.2{\pm}6.4$. The blood vessel density was not statistically related to lymph node metastasis. (p>0.05) These results suggest that angiogenesis may be related to the local invasion of OSCC and further research will be needed to investigate the possibility that antiangiogenic agent can be used as an anticancer agent for OSCC.
