Background: Cancer survivors are at increased risk of second cancers. Lymphoproliferative disorders (LPD) are common neoplasms that are primary or subsequent cancers in cases of multiple primary cancer. We here analyzed metachronous or synchronous LPD in multiple primary cancers. Methods: Between 2001 and 2010, LPD were assessed retrospectively in 242 multiple primary cancers patients. Results: Forty nine (20.2%) patients with LPD were detected. Six patients had two LPD where one patient had three LPD. The median age of patients was 60.5 years (range: 28-81). LPD were diagnosed in 29 patients as primary cancer, in 23 patients as second cancer, and in three patients as third cancer in multiple primary cancers. Primary tumor median age was 56 (range: 20-79). Diffuse large B cell lymphoma (n=16), breast cancer (n=9), and lung cancer (n=6) were detected as subsequent cancers. Alklylating agents were used in 19 patients (43.2%) and 20 patients (45.5%) had received radiotherapy for primary cancer treatment. The median follow-up was 70 months (range: 7-284). Second malignancies were detected after a median of 51 months (range: 7-278), and third malignancies with a median of 18 months (range: 6-72). Conclusions: In this study, although breast and lung cancer were the most frequent detected solid cancers in LPD survivors, diffuse large B cell lymphoma was the most frequent detected LPD in multiple primary cancers.

Medical verification of cancer diagnosis in insurance claims is a very important procedure in insurance administrations. Claims staffs are in need of medical experts' opinions about claim administration. This procedure is called medical claim review (MCR) and is composed of verification and advice. MCR verification evaluates the insured’s physical condition by medical records and compares it with product coverage. It is divided into assessment of living assurance benefit, verification of cancer, and assessment of the cause of death. Actually cancer verification of MCR is applicable to coding because the risk ratio in product development is usually coded data. There are some confusing neoplastic diseases in assessing the verification of cancer. This article reviews gastrointestinal stromal tumors (GIST) and mucosa-associated lymphoid tissue tumors (MALToma) of the stomach. The second most common group of stromal or mesenchymal neoplasms affecting the gastrointestinal tract is GIST. Nowadays there are many articles about the pathophysiology of GIST. However there are few confirmative theories except molecular cell biology of KIT mutation and some tyrosine kinase. Therefore, coding the GIST, which has previously been classified as an intermediate risk group according to NIH2001 criteria, for cancer verification of MCR is suitable for D37.1; neoplasm of uncertain or unknown behavior of digestive organs and the stomach. The gastrointestinal tract is the predominant site of extranodal non-Hodgkin's lymphomas. B-cell lymphomas of the MALT type, now called extranodal marginal zone B-cell lymphoma of MALT type in the REAL/WHO classification, are the most common primary gastric lymphomas worldwide. Its characteristics are as follows. First, it is different from traditional stomach cancers such as gastric adenocarcinoma. Second, the primary therapy of MALToma is the eradication of H. pylori by antibiotics and the remission rate is over 80%. Third, it has a different clinical course compared to traditional malignant lymphoma. Someone insisted that cancer verification is not possible for the above reasons. However, there have been findings on pathologic mechanism, and according to WHO classification, MALToma is classified into malignant B-cell lymphoma and it must be verified as malignancy in MCR.
On an international scale, the burden of cancer in absolute numbers continues to increase, mainly due to aging of population in many countries, the overall growth of the world population, changing lifestyle with increasing cancer-causing behavior, like cigarette smoking, changing dietary habits and sedentary life. Cancer is the second-leading cause of death and disability in the world, after only heart disease. Recently, increasing incidence and mortality of cancer have also become evident in the developing world. In Iraq and particularly in Basrah in the southern part of the country, the burden has definitely increased and deserves extensive research. The present paper is part of an extensive household survey carried out in Basrah in 2013. Among the objectives was to validate official cancer registration in the governorate. The cross-sectional survey had a retrospective component to inquire about the incidence of cancer and cancer-related deaths during the three years preceding the date of inquiry (2010-2012). A convenient sample of 6,999 households with 40,688 inhabitants using multistage cluster sampling was surveyed involving all urban and rural areas of Basrah. The official cancer registration activities in Basrah seemed to have attained a high level of registration coverage (70-80%) but the gap, represented by missed cases, is still high enough to criticize the system. Most of the missing cases were either not notified by treating facilities or they were diagnosed and treated outside Basrah. Using a set of parameters, the pattern of cancer was consistent based on data of the household survey and data of the cancer registry but a gap still existed in the coverage of incident cancer and mortality by cancer registration. Integrated serious steps are required to contain the risk of cancer and its burden on the patient through improving the registration process, improving early detection, diagnostic and management capabilities and encouraging scientific research to explore the hidden risk factors and possible causes of low registration coverage. Periodic household surveys seemed feasible and essential to support routine registration.
Of all gynecologic cancers, endometrial cancer is the most common cancer in the US and Europe. In addition, it is presently the second most common gynecologic cancer in the world. As a result of increasing menopausal, obese and tamoxifen use women, the incidence of the cancer seems to be on the increase. Surgery is the major treatment, whereas postoperative radiation therapy in high-intermediate risk patients many prevent locoregional recurrence. Adjuvant chemotherapy can improve progression free survival in advanced or recurrent cancers. Molecular targeted therapies are now a focus of attention including anti-vascular endothelial growth factor (VEGF), mammalian target of rapamycin (mTOR) inhibitor and tyrosine kinase inhibitor (TKI). They may provide useful future strategies for control of endometrial malignancies in developing countries and across the world.
Background: Cervical cancer is the second most common in Thailand, but the mortality rate may be rising yearly. It is a cancer that can be prevented by early screening for precancerous lesions, several methods being available. Objective: To identify the prevalence of abnormal Papanicolaou (Pap) smears and lesions with visual inspection with acetic acid (VIA) in pregnant women and assess risk factors for this group. Materials and Methods: This prospective study was performed at Prapokklao Hospital, Thailand during April-July 2016. All pregnant women of gestational age between 12-36 weeks who attended an antenatal clinic were recruited. All participants were screened for cervical cancer by Pap smear and VIA. If results of one or both were abnormal, colposcopic examination was evaluated by gynecologic oncologist. Results: A total of 414 pregnant women were recruited. Prevalence of abnormal Pap smear and VIA were 6.0 and 6.7 percent, respectively. The most common abnormal Pap smear was low grade intraepithelial lesion (LSIL, 44%). Factors associated with abnormal Pap smear in pregnant women were low BMI, multiple partners and being a government officer. In pregnancy, Pap smear had higher sensitivity and specificity than VIA for detection of precancerous cervical lesion. Patients with young coitarche or more than 25 years of active sexual activity were high risk groups. Conclusions: Prevalence of abnormal Pap smear and VIA in pregnant women was 6.0 and 6.7 percent, respectively. Factors associated with abnormal Pap smear were coitarche, years of sexual activity, low BMI, multiple partners and being a government officer.
Introduction: Quality of life (QoL) issues are of importance in relatives of women with breast cancer (BC)as caregivers in neglecting their own needs due to care of a patient and also as women regarding the potential risk of themselves developing BC. The objectives in the present study were to compare the QoL of female relatives of women in treatment for breast cancer. To date, no study had examined multi-dimensional QoL in accompanying people as compared them into two groups of female relatives whose first degree and second degree. Methods: QoL of female relatives was assessed using the Quality of Life-Family Version (QOL-FV) scale. Relationships between socio-demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and Crosstabs tests. Results: The mean age of the female relatives was 37.6 years, and nearly 48% had a university education. It was found that first degree relatives had worse QoL in all domains except physical wellbeing than second degree relatives. Conclusion: This study showed that being female relatives of BC, especially first-degree, affect QoL negatively. Health care providers are of an important role in the stage of information related to genetic influence of BC.

Prostate cancer is a high-risk with a high incidence and is a disease that occurs only in men. Accurate diagnosis of cancer is necessary as the incidence of cancer patients is increasing. Prostate cancer is also a disease that is difficult to predict progress, so it is necessary to predict in advance through prognosis. Therefore, in this paper, grade classification is attempted based on texture feature extraction. There are two main methods of classification: Uses One-way Analysis of Variance (ANOVA) to determine whether texture features are significant values, compares them with all texture features and then uses only one classification i.e. Benign versus. The second method consisted of more detailed classifications without using ANOVA for better analysis between different grades. Results of both these methods are compared and analyzed through the machine learning models such as Support Vector Machine and K-Nearest Neighbor. The accuracy of Benign versus Grade 4&5 using the second method with the best results was 90.0 percentage.
Background: Associations between the NQO1 C609T polymorphism and hepatocellular carcinoma (HCC) risk are a subject of debate. We therefore performed the present meta-analysis to evaluate links with HCC susceptibility. Materials and Methods: Several major databases (PubMed, EBSCO), the Chinese national knowledge infrastructure (CNKI) and the Wanfang database were searched for eligible studies. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to measure the strength of associations. Results: A total of 4 studies including 1,325 patients and 1,367 controls were identified. There was a significant association between NQO1 C609T polymorphism and HCC for all genetic models (allelic model: OR=1.45, 95%CI=1.23-1.72, p<0.01; additive model: OR=1.96, 95%CI=1.57-2.43, p<0.01; dominant model: OR=1.62, 95%CI=1.38-1.91, p<0.01; and recessive model: OR=1.53, 95%CI=1.26-1.84, p<0.01). On subgroup analysis, similarly results were identified in Asians. For Asians, the combined ORs and 95% CIs were (allelic model: OR=1.50, 95%CI=1.24-1.82, p<0.01; additive model: OR=2.11, 95%CI=1.48-3.01, p<0.01; dominant model: OR=1.69, 95%CI=1.42-2.02, p<0.01; and recessive model: OR=1.59, 95%CI=1.16-2.19, p<0.01). Conclusions: The current meta-analysis suggested that the NQO1 C609T polymorphism could be a risk factor for developing HCC, particularly in the Chinese population.
Objective: The study was planned with the purpose of examining the attitude of women who have pap-smear test for the early diagnosis of cervical cancer, factors affecting their decisions and their feelings and experiences during this period. Materials and Methods: A phenomenological method was used. Data were collected between March 2012 and April 2012 using standard and purposive samplings from 17 women. A detailed interview with women were held in their houses and recorded. The data collection tool consisted of two parts, one of which is information form with 17 questions identifying sociodemographic and cervical cancer risk factors of women and the second part is made up of semi-structured interview form with 15 alternative questions taking literature and the pap-smear test into consideration. Collected data were put into a written document. Content analysis was held by loading the documents into NVIVO 8 Statistical Programme. Results: The study comprised themes such as cervical risk factor, decision of taking pap-smear test, taking pap-smear test, knowledge about pap-smear test, relieving factors during pap-smear test, obstructive factors during pap-smear test, gynecological examination and feelings of women during and after pap-smear test while waiting for the results. Conclusions: As women perceive gynaecological examinations differently from other examinations, they have different feelings in each process of the Pap smear test. Medical staff should advise women more clearly on the nature and advantages of the Pap-smear test.
The objective of this retrospective study was to investigate prognostic factors associated with survival of patients with extensive stage small cell lung cancer (ES-SCLC). Included were 200 patients admitted to the Liberation Army General Hospital with a diagnosis of ES-SCLC. The demographics of patients, disease characteristics, pre-treatment biochemical parameters and therapeutic plan were assessed or evaluated. Univariate analysis found that second-line chemotherapy, radiotherapy, and no liver metastasis were associated with improved survival. Tumor response to first-line chemotherapy and normal initial hemoglobin levels were also associated with a survival benefit (all P-values ${\leq}$ 0.0369). Multivariate Cox regression analysis indicated that liver metastasis and the total number of all chemotherapy cycles were independent prognostic factors of survival. The morbidity risk in patients with liver metastasis was 2.52-fold higher than that in patients without liver metastasis (hazard ratio (HR)=2.52 (1.69-3.76); P<0.0001). However, one unit increase in the total number of chemotherapy cycles decreased the risk of death by 0.86-fold (HR=0.86 (0.80-0.92); P<0.0001). Absence of liver metastasis and ability of a patient to receive and tolerate multiple lines of chemotherapy were associated with longer survival.
