    Conclusion: According to the observed changes in incidence rate, the burden of uterine corpus cancer in the general female population is expected to increase in the near future. From a public-health perspective, care providers should develop strategies for the prevention, early detection, and intervention to reduce the rapidly increasing incidence of uterine corpus cancer in Taiwan.

    The association of uterine leiomyoma with increased risk of breast cancer is controversial. Therefore, we used the National Health Insurance Research Database of Taiwan to examine breast cancer incidence and mortality among Asian patients with and without uterine leiomyoma. We compared breast cancer incidence and mortality between 22,001 newly diagnosed uterine leiomyoma patients and 85,356 individuals without uterine leiomyoma matched by age and date of diagnosis. Adjusted hazard ratios for breast cancer were estimated using the Cox model. The incidence of breast cancer was 35% higher in the uterine leiomyoma group than the leiomyoma-free group (1.65 vs. 1.22 per 1,000 individuals, p leiomyoma group (mean followed time, 3.59 ± 2.70 years) than the leiomyoma-free group (8.78%; mean followed time, 3.54 ± 2.67 years) at the endpoint of the study (p leiomyoma than in those without it, but overall mortality from breast cancer was lower in the patients with uterine leiomyoma.

    There is a serious, and growing, concern about the increased risk of the emergence of a second cancer, induced by radiation associated with the radiation treatment. To assess the radiation doses to organs outside the target volume, in this work, we modeled several computational exposure scenarios, based on Monte Carlo simulation (MCNPX code). We used a VARIAN 2100c accelerator, and a female virtual anthropomorphic phantom to simulate a treatment of uterine cancer. The results presented show that the computational exposure scenario provides a versatile and accurate tool to assess the risk of secondary cancer. (author)

    As a cause of death in females, cancer of the uterus is one of the important cancers in Japan. In 1962 it was responsible for 15.5% of all the deaths due to cancer in women and ranked next to the proportion attributed to cancer of the stomach. The JNIH-ABCC Life Span Study of A-bomb survivors also shows that cancer of the stomach and uterus were the major causes of cancer deaths in the female population. The present study, which was carried out in 1963, was begun in the hope of elucidating some of the relationships of the factors other than radiation possibly associated with the incidence of cancer of the uterus in the Life Span Study (ST 100) sample in Horoshima. Environmental factors considered to play a role in the development of uterine cancer were studied by interview with a close relative of the subject. The data did not clearly support the findings reported elsewhere that residential history, occupational history, history of marital status, smoking and alcohol drinking habits, and socioeconomic factors were associated with the incidence of cancer of the uterus. A brief analysis was also conducted for the accuracy of death certificates. The results suggest that an epidemiologic study should be conducted on morbidity data derived from pathologic findings and a revised plan is desirable to elucidate the factors associated with the incidence of cancer of the uterus using the various recent experimental findings as references. 124 references, 15 tables.

    To study the relative risk of second cancer after radiotherapy, we reviewed 2465 cases of uterine cervical cancer who were treated in our institute from 1962 to 1986 and were followed up for more than 5 years. Among them, 1502 cases were treated by radiotherapy with or without surgery (radiotherapy group), and the remainder were treated by surgery only (surgery only group). We defined second cancer as malignancy that occurred in another organ after an interval of 5 years or more from the end of treatment of the first cancer. The relative risk of second cancer was computed by the person-year method advocated by Schoenberg. Second cancer was observed among 8 cases of the surgery group, whereas 43 cases were observed among the radiotherapy group. The cases were: rectal cancer, 6 cases; bladder cancer, 4 cases. The observed and expected ratio (O/E ratio) was 4.02 in rectal cancer and 7.98 in bladder cancer. This incidence of the both cancers was significantly high in the radiotherapy group. Three of the 6 cases with rectal cancer underwent operation in our institute. The incubation periods between the first and second cancers were from 9 to 21 years. Each case exhibited symptoms of chronic radiation proctitis after radiotherapy for uterine cervical cancer. It is thought necessary to follow up such cases carefully to detect radiation induced cancer. (author)

    Uterine leiomyomas sometimes show focal 18 F-fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) images that may result in a false-positive diagnosis for malignant lesions. This study was conducted to investigate the incidence and characteristics of uterine leiomyomas that showed FDG uptake. We reviewed FDG-PET and pelvic magnetic resonance (MR) images of 477 pre-menopausal (pre-MP, age 42.1±7.3 years) and 880 post-MP (age 59.9±6.8 years) healthy women who underwent these tests as parts of cancer screening. Of 1357, 323 underwent annual cancer screening four times, 97 did three times, 191 did twice, and the rest were screened once. Focal FDG uptake (maximal standardized uptake value >3.0) in the pelvis was localized and characterized on co-registered PET/MR images. Uterine leiomyomas were found in 164 pre-MP and 338 post-MP women. FDG uptake was observed in 18 leiomyomas of 17 of the 164 (10.4%) pre-MP women and in 4 leiomyomas of 4 of the 338 (1.2%) post-MP women. The incidence was significantly higher in pre-MP women than in post-MP women (chi-square, P<0.001). Of the 22, 13 showed signal intensity equal to or higher than that of the myometrium on T2-weighted MR images, which suggested abundant cellularity, whereas the majority of leiomyomas without FDG uptake showed low signal intensity. Of the 13 women, 12 examined more than twice showed substantial changes in the level of FDG uptake in leiomyomas each year with FDG uptake disappearing or newly appearing. These changes were observed frequently in relation with menopause or menstrual phases. Leiomyomas with focal FDG uptake were seen in both pre- and post-MP women with a higher incidence in pre-MP women. Abundant cellularity and hormonal dependency may explain a part of the mechanisms of FDG uptake in leiomyomas. It is important to know that the level of FDG uptake in leiomyomas can change and newly appearing FDG uptake does not necessarily mean malignant transformation. (author)

    An ongoing debate over the last two decades has focused on whether fertility treatment in women may lead to an increased risk of developing uterine cancer over a period of time. Uterine cancer (including mainly endometrial carcinoma and the less common uterine sarcoma) is the commonest reproductive tract cancer and the fourth commonest cancer in women in the UK. Our objective was to assess the association between fertility drugs used in the treatment of female infertility (both as an independent therapy and during in vitro fertilization cycles) and the development of uterine cancer. A literature search was performed using Medline, Embase, Cochrane Library and Google Scholar databases for comparative studies until December 2014 to investigate a clinical significance of fertility treatment on the incidence of developing uterine cancer. General and MESH search headings, as well as the 'related articles' function were applied. All comparative studies of 'fertility treatment' versus 'non-fertility treatment' reporting the incidence of uterine cancer as an outcome were included. Uterine cancer incorporated the following terms: uterine cancer, uterine body tumours, uterine sarcomas and endometrial cancers. The primary outcome of interest was the uterine cancer incidence in all 'fertility treatment' versus 'non-fertility treatment' patient groups. Secondary outcomes of interest were: (a) uterine cancer incidence in 'IVF' versus 'non-IVF' patient groups; and (b) uterine cancer incidence according to type of fertility drug used. Odds ratio was the summary statistic. Random-effects modelling, graphical exploration and sensitivity analysis were used to evaluate the consistency of the calculated treatment effect. We included six studies in our final analysis, which comprised 776,224 patients in total. Of these, 103,758 had undergone fertility treatment and 672,466 had not. There was 100% agreement between the two reviewers regarding the data extraction. All the studies

    Objective: Describe a pathology with a high incidence in our means, in association with pregnancy in this case, graphically report they type of cervical malignancy, clinical manifestations, diagnose and treatment according to stage. Clinical case: We present a young patient with cervical pathology (endofitic bleeding lesion) diagnosed during the first trimester of pregnancy, with complete pregnancy, that consult because of genital bleeding, founding an endofitic lesion by colposcopic exam and which biopsy and pap test reported a scamous cell carcinoma, image diagnostic procedures reveal a 6 month product, that after surgical ending of pregnancy, wa treated by radical hysterectomy. Conclusions: It is important to recognize that in cervical pathology; cervical cancer during pregnancy is a great challenge for the specialist, the diagnostic evaluation that includes biopsies, must be realized in the same way, except from the endocervical canal. The treatment of choice for women is early stages of pregnancy is radical hysterectomy, during the last half of pregnancy it is possible to wait the viability of the product planning the childbirth surgically as soon as possible.

    In this article, we present the views on uterine cancer of the ancient Greek physicians. We emphasize on uterine's cancer aetiology according to the dominant in antiquity humoural theory, on its surgical treatment suggested by Soranus of Ephesus, and in the vivid description provided by Aretaeus of Cappadocia. During that period, uterine cancer was considered as an incurable and painful malignancy and its approach was mainly palliative.

    By means of re-irradiation using pepleomycin suppository in uterine cavity, we attained local control for one patient who had local recurrence in uterine cavity and suffered from uterine fluor in which viable cancer cells were confirmed. We were enlightened by this therapeutic experience, so we attempted combination therapy using pepleomycin suppositories to supplement intra-cavitary irradiation, for the 11 selected patients who were suffering from uterine fluor. We investigated the treatment results in 7 patients of stage III out of 11 patients (of all stages), in comparison with 13 patients of stage III who were treated by irradiation alone. Consequently, these treatment results were approximately equivalent, and the incidence of sigmoid complications could be decreased. Side effects which were followed by the combination therapy were not serious, and so we believe that pepleomycin suppository is a simple method and valuable to supplement radiation therapy of uterine cervical cancer.

    Purpose : This study was done to analyze survivals, patterns of failure, and complications of early uterine cervix cancer after curative radiotherapy. Methods and Materials : Eighty patients with uterine cervix cancer FIGO Stage IB (48 cases) and Stage IIA (32 cases) treated with radiotherapy were analyzed retrospectively. Patients were treated from November 1985 to May 1993, and minimum follow up period was 24 months. and 6 cases were lost to follow up. All of them were treated with external radiotherapy and different fractions of high dose rate intracavitary radiotherapy. Survival rates, failure patterns, complication rates and degrees of severity were analyzed according to several factors. Results : Overall 5 year survival rate and relapse free survival rate were 72.3%, and 72.8% respectively. Prognostic factors were stage, size, pathology, RT response and there was no significant survival difference among the reasons of radiotherapy choice. There were 19 cases of treatment failure, another 3 cases were not tumor related death, and most of treatment related failure occurred within 24 months. Late complication rate of bladder and rectum were 8.8%, 15% respectively, frequency and severity of complication were correlated with ICR fractionation dose and total dose. Conclusion : These results showed that survival rates of early stage radiation treated cervix cancer patients were comparable to surgical series, but more aggressive treatment methods needed for stage IIA poor prognostic patients, To decrease late complication, choice of proper ICR dose and meticulous vaginal packing is needed

    We investigated the incidence and clinical appearance of late adverse intestinal effects in 88 patients treated with postoperative radiotherapy and 46 patients treated with radiotherapy alone for uterine cervical cancer. In the postoperative radiotherapy group, colitis, ileus and bowel fistules were seen in 13 patients (14.8%), 8 (9.1%), and 3 (3.4%) of the patients, respectively. Of these patients, 11 (12.5%) needed to have surgical therapy for these adverse effects. In the radiation alone group, 18 patients (39.1%) had colitis and 2 (4.3%) had ileus; of them, 2 patients (4.3%) needed to have surgical therapy. The higher incidence of so severe adverse effects as to require surgical therapy in the postoperative radiotherapy group indicates that adhesion caused by operation might have caused the occurrence of these adverse effects. Four of a total of 134 patients died of causes which might be attributable to irradiation. In 61 patients treated by radical hysterectomy without postoperative radiotherapy, intestinal adverse effects were not found. These results indicate that late intestinal adverse effects after radiotherapy are likely to occur in some cases very severely; therefore, careful consideration is necessary in the decision to use radiotherpay for uterine cervical cancer.

    Adult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically. By contrast, radiation is detrimental to both the ovaries and the uterus, thereby causing a greater magnitude of adverse effects on the female reproductive function. These include infertility, premature ovarian failure, miscarriage, fetal growth restrictions, perinatal deaths, preterm births, delivery of small-for-gestational-age infants, preeclampsia, and abnormal placentation. Regrettably, the majority of these adverse outcomes arise from radiation-induced uterine injury and are reported at higher incidence in the adult survivors of childhood cancers who were exposed to uterine radiation during childhood in the form of pelvic, spinal, or total-body irradiation. Recent findings of long-term follow-up studies evaluating reproductive performance of female survivors provided some reassurance to female cancer survivors by documenting that pregnancy and live birth rates were not significantly compromised in survivors, including those who had been treated with alkylating agents and had not received pelvic, cranial, and total-body irradiation. We aimed in this narrative review article to provide an update on the impact of chemotherapy and radiation on the ovarian and uterine function in female survivors of childhood cancer. Adult survivors of childhood cancers are more prone to developing a number of poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation

    Treatment results for uterine cervix cancer were evaluated using a new concept named ''Effective Survival Rate''. This rate was calculated by subtracting the weighted sum of incidence rates of various complications from the 5-year survival rate. The numerical values for various complications were assigned as follows: surgical death, 1.0; severe complications, such as fistula ureterovaginalis and ileus, 0.5; mild complications, such as rectum and urinary bladder complications, 0.3 and 0.2. These values were determined with reference to the Karnofsky index of performance status. The effective survival rate was calculated for patients with satage 2 and 3 uterine cervix cancer treated by radiation therapy and surgery, and compared as a function of age between 30 and 70 years. We concluded that the effective survival rate was comparable for radiation therapy and surgery for stage 2 uterine cervix cancer. However, in patients with stage 3, radiation therapy was superior.

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated. (authors)

    Full Text Available Women in the U.S. Commonwealth of Puerto Rico (PR have a higher age-adjusted incidence rate for uterine cervix cancer than the U.S. mainland as well as substantial access and economic barriers to cancer care. The National Cancer Institute (NCI funds a Minority/Underserved NCI Community Oncology Research Program in PR (PRNCORP as part of a national network of community-based health-care systems to conduct multisite cancer clinical trials in diverse populations. Participation by the PRNCORP in NCI’s uterine cervix cancer clinical trials, however, has remained limited. This study reports on the findings of an NCI site visit in PR to assess barriers impeding site activation and accrual to its sponsored gynecologic cancer clinical trials. Qualitative, semi-structured individual, and group interviews were conducted at six PRNCORP-affiliated locations to ascertain: long-term trial accrual objectives; key stakeholders in PR that address uterine cervix cancer care; key challenges or barriers to activating and to enrolling patients in NCI uterine cervix cancer treatment trials; and resources, policies, or procedures in place or needed on the island to support NCI-sponsored clinical trials. An NCI-sponsored uterine cervix cancer radiation–chemotherapy intervention clinical trial (NCT02466971, already activated on the island, served as a test case to identify relevant patient accrual and site barriers. The site visit identified five key barriers to accrual: (1 lack of central personnel to coordinate referrals for treatment plans, medical tests, and medical imaging across the island’s clinical trial access points; (2 patient insurance coverage; (3 lack of a coordinated brachytherapy schedule at San Juan-centric service providers; (4 limited credentialed radiotherapy machines island-wide; and (5 too few radiology medical physicists tasked to credential trial-specified positron emission tomography scanners island-wide.

    Full Text Available This paper works at segmentation of lesion observed in cervical cancer, which is the second most common cancer among women worldwide. The purpose of segmentation is to determine the location for a biopsy to be taken for diagnosis. Cervix cancer is a disease in which cancer cells are found in the tissues of the cervix. The acetowhite region is a major indicator of abnormality in the cervix image. This project addresses the problem of segmenting uterine cervix image into different regions. We analyze two algorithms namely Watershed, K-means clustering algorithm, Expectation Maximization (EM Image Segmentation algorithm. These segmentations methods are carried over for the colposcopic uterine cervix image.

    This paper describes the present state of radiotherapy (RT) of early stage cervical cancer involving the history, outcomes of clinical trials, procedure for each stage, irradiation methods, concurrent chemo-RT (CCRT), late adverse events, and QOL after RT. It has a history of >100 years from the brachytherapy with radium, but is not yet completely established even now. There are many RT trials hitherto. Retrospectively, no significant difference is seen in outcomes of radical RT and surgery: 80-90% efficacy for stage I and 60-80% for II in the former, respectively, and 80-96% and 65-80%, in the latter. Between RT and surgery, there is a report of randomized comparative study in Italy. In Japan, reported are comparative outcomes based on patients' choice for therapy, retrospective studies including authors' one, prospective multi-institutional cooperative trials by Japanese Radiation Oncology Study Group, and Treatment Guidelines for Cervical Cancer (2007). RT procedure depends on the stage defined by FIGO (International Federation of Gynecology and Obstetrics) and at stages I-II, intracavitary RT is major with optimal dose 29 Gy/5 fractions for I, and 23/4 Gy with external total pelvic radiation 50 Gy for II. In external radiation, the planning target volume includes the whole pelvic field with 1.8-2 Gy/5 weeks and optionally, the extended field when metastasis suspicious. Intracavitary RT with application device in the uterine is of significance for the cancer as 50% complete cure even in stage III is reported. CCRT brings about good prognosis, which is shown in a Japanese trial to compare postoperative RT alone and CCRT with CDDP and 5-FU. The late adverse events are seen mainly in the large bowel and studies of QOL, an important factor for choice of treatment, are now in progress. (T.T.)

Cancer incidence was especially low among Anglo-American males for cancer of the lung and oral cancer, cancer sites commonly associated with cigarette smoking. No cases of cancer of the lung, oral cavity, pancreas, or bladder were observed among Anglo-American females in the population. Standardized incidence ratios for cancer of the breast and cancer of the uterine corpus exceeded one; however, these findings were not statistically significant. These findings are consistent with expectation for a population of high socioeconomic class, such as the Laboratory work force. Therefore, working conditions at the Laboratory do not appear to have affected cancer incidence in this population. 1 reference, 2 tables

    Forty seven patients with locally recurrent uterine cerival cancer after surgery were treated with radiation during the 6 year period from 1979 through 1984 at the Department of Therapeutic Radiology of Seoul National University Hospital. In 30 out of the 47 patients, recurrence was diagnosed within 2 years after surgery. Site of recurrence was vagina in 19 patients, vagina and parametrium in 21 patients and parametrium only in 7 patients. Complete tumor control was achieved in 35 patients (74.5%) ; the complete response rates were 94.7% (18/19( in vaginal recurrences, 57.1% (12/21) in combined vaginal and parametrial recurrences and 71.4% (5/7) in parametrial recurrences. Overall and disease free survival rates at 4 years were 55.2 and 50.1 percent, respectively, for entire group. Overall 4 year survival rates were 77.0% for vaginal recurrences, 44.1% for vaginal and parametrial recurrences and 42.9% for parametrial recurrences. When the disease extent was classified in the same way as the staging system of FIGO, the 4 year survival was 80.4, 73.0, 25.0 and 0 percent for stage IIa, IIb and IVa, respectively

    Full Text Available Introduction. Uterine fibroid tumors (uterine leiomyomas are the most common benign uterine tumors. The incidence of uterine fibroid tumors increases in older women and may occur in more than 30% of women aged 40 to 60. Many uterine fibroid tumors are asymptomatic and are diagnosed incidentally. Case Presentation. A 44-year-old woman was admitted to our hospital with general weakness, dyspepsia, abdominal distension, and a palpable abdominal mass. An abdominal computed tomography scan showed a huge tumor mass in the abdomen which was compressing the intestine and urinary bladder. Gastroduodenal endoscopic and biopsy results showed a Borrmann type IV gastric adenocarcinoma. The patient was diagnosed with gastric cancer with disseminated peritoneal carcinomatosis. She underwent a hysterectomy with both salphingo-oophorectomy and bypass gastrojejunostomy. Simultaneous uterine fibroid tumor with other malignancies is generally observed without resection. But in this case, a surgical resection was required to resolve an intestinal obstruction and to exclude the possibility of a metastatic tumor. Conclusion. When a large pelvic or ovarian mass is detected in gastrointestinal malignancy patients, physicians try to exclude the presence of a Krukenberg tumor. If the tumors cause certain symptoms, surgical resection is recommended to resolve symptoms and to exclude a metastatic tumor.

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

    Previous studies indicate that cervical cancer is the second most frequent cancer and most common cause of cancer mortality among women in Fiji. There is little published data on the epidemiology of cervical cancer in Pacific countries. To determine the incidence 2003-2009 of, and mortality 2003-2008 from, cervical cancer by ethnicity and period in Fiji, identify evidence of secular change and relate these data to other Pacific countries, Australia and New Zealand. Counts of incident cervical cancer cases (2003-2009) and unit record mortality data (2003-2008) from the Fiji Ministry of Health were used to calculate age-standardised (to the WHO World Population) cervical cancer incidence and mortality rates, and cervical or uterine cancer mortality rates, by ethnicity, with 95% confidence intervals. On the basis of comparison of cervical cancer mortality with cervical or uterine cancer mortality in Fiji with similar populations, misclassification of cervical cancer deaths is unlikely. There is no evidence of secular change in cervical cancer incidence and mortality rates for the study period. For women of all ages and ethnicities, the age-standardised incidence rate of cervical cancer (2003-2009) was 27.6 per 100,000 (95% CI 25.4-29.8) and the age-standardised mortality rate (2003-2008) was 23.9 per 100,000 (95% CI 21.5-26.4). The mortality/incidence ratio was 87%. Fijians had statistically significant higher age-standardised incidence and mortality rates than Indians. Fiji has one of the highest estimated rates of cervical cancer incidence and mortality in the Pacific region. Cervical cancer screening in Fiji needs to be expanded and strengthened. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Physical activity (PA) is known to provide physical and mental health benefits to uterine cancer survivors. However, it is unknown if PA is associated with lower limb lymphedema (LLL), an accumulation of protein-rich fluid in the lower limbs. Therefore, we sought to examine the association between PA and LLL in uterine cancer survivors, with a focus on walking. We conducted a cross-sectional study using mailed surveys among uterine cancer survivors who received care at a university-based cancer center. We asked about PA, walking, and LLL symptoms using validated self-report questionnaires. PA was calculated using MET-hours per week, and walking was calculated using blocks per day. The response rate to our survey was 43%. Among the 213 uterine cancer survivors in our survey, 36% were classified as having LLL. Compared with participants who reported trend = 0.003). Stratified analyses suggested the association between PA and LLL existed only among women with body mass index (BMI) trend = 0.007) compared with women with BMI ≥ 30 kg · m (P trend = 0.47). Compared with participants who reported trend trend = 0.007) and women with BMI ≥ 30 kg · m (P trend = 0.03). Participation in higher levels of PA or walking is associated with reduced proportions of LLL in dose-response fashion. These findings should be interpreted as preliminary and should be investigated in future studies.

    Objective The incidence for uterine cancers has been reported to be higher among white women, whereas mortality is higher among black women. Reasons for the higher mortality among black women are not completely understood. The aim of our study is to examine the relationship between race/ethnicity, histopathologic subtype, and survival in uterine cancer. Methods We abstracted socio-demographic, treatment, and survival data for all women who were diagnosed with uterine cancer at Montefiore Medical Center from January 1999 through December 2009. Pathology records were reviewed. Results 984 patients were identified. Racial/ethnic distribution was 382 (39%) white, 308 (31%) black, 232 (24%) Hispanic, and 62 (6.3%) other races, mixed, or unknown. 592 (60%) patients had endometrioid histology. Blacks were much more likely than whites to have non-endometrioid histologies (p<0.001), including papillary serous, carcinosarcoma, and leiomyosarcoma. Blacks and Hispanics were at least as likely as whites to receive either chemotherapy or radiation therapy. The hazard ratio for death for black versus white patients was 1.94 (p<0.001) when all histological subtypes were included. The hazard ratio for Hispanics for death was 1.2 (p=0.32) compared to whites. However, when patients were divided into endometrioid and non-endometrioid histological subtypes, there was no significant difference in survival by race/ethnicity. Conclusion Black patients with uterine cancer are much more likely to die and are much more likely to have non-endometrioid histologies than white patients. There are no differences in survival among white, black, or Hispanic women with uterine cancer, after control for histological subtype. PMID:22940487

    Periodic cancer incidence estimates of Spain from all existing population-based cancer registries at any given time are required. The objective of this study was to present the current situation of cancer incidence in Spain. The Spanish Network of Cancer Registries (REDECAN) estimated the numbers of new cancer cases occurred in Spain in 2015 by applying the incidence-mortality ratios method. In the calculus, incidence data from population-based cancer registries and mortality data of all Spain were used. In 2015, nearly a quarter of a million new invasive cancer cases were diagnosed in Spain, almost 149,000 in men (60.0%) and 99,000 in women. Globally, the five most common cancers were those of colon-rectum, prostate, lung, breast and urinary bladder. By gender, the four most common cancers in men were those of prostate (22.4%), colon-rectum (16.6%), lung (15.1%) and urinary bladder (11.7%). In women, the most common ones were those of breast (28.0%), colon-rectum (16.9%), corpus uteri (6.2%) and lung (6.0%). In recent years, cancer incidence in men seems to have stabilized due to the fact that the decrease in tobacco-related cancers compensates for the increase in other types of cancer like those of colon and prostate. In women, despite the stabilization of breast cancer incidence, increased incidence is due, above all, to the rise of colorectal and tobacco-related cancers. To reduce these incident cancer cases, improvement of smoking control policies and extension of colorectal cancer screening should be the two priorities in cancer prevention for the next years.

    Full Text Available The purpose of this study was to investigate the effect of fermented mushroom of Cordyceps sinensis (CS, rich in selenium (Se-CS, on uterine cervical cancer in mice. The methylcholanthrene- (MCA- induced tumor model was used in this paper. After the mice were administered Se-CS, the animals showed 40% tumor incidence (P<0.05. Se-CS also enhanced the immune functions. Se-CS treatment showed significant (P<0.05–0.01 restoration in the level of glutathione content, lipid peroxidation, glutathione peroxidase activity, glutathione reductase activity, catalase activity, Na+/K+-ATPase activity, and glutathione S transferase activity. This finding suggested that the concomitant use of Se and CS could be a potential therapeutic approach to improve the efficacy of therapy for uterine cervical cancer.

    Full text: Introduction: The aging population and improved medical care lead to increased likelihood for patients experienced a tumor to develop at least one more in the course of his life. The aim of the study was to analyze the clinical and biological characteristics and survival of patients with primary tumor multiplicity in which a tumor is cancer of the uterine body. Materials and Methods: For the period 1997-2007, in the department of radiotherapy were treated 191 women with carcinoma of the uterine body (in a group of moderate and high risk) with invasion of the myometrium more than one third. Patients ranged in age from 36 to 77 (average age 59.9) and were followed until 31.03.2013 with an average follow-up period 126 months. Postoperatively, all were carried intravaginal brachytherapy with high dose rate 3x5 Gy once a week, followed by percutaneous radiotherapy 22x2 Gy daily to the area of the pelvic lymph nodes. Data to diagnose combined tumors were obtained from the National Cancer Registry. Survival analysis was made by the method of Kaplan - Meier with Lograng test. Results: In 26 (13.6 %) of the analyzed patients a tumor multiplicity is find in 22 (84,6%) tumors are two in 3 (11.5 %)- three , and in 1 (3.8%) - four . A detailed analysis of 14 (53.8%) patients whose cancer of the uterine body is the first tumor and is followed by another. The distribution of the tumor according to the second location is: breast cancer 5 (35.7%) skin malignant melanoma without 4 (28.5%) of the column 3 (21.4 %) of stomach 1 (7.1%) , MALT lymphoma, 1 (7.1% ) . Evaluate and compare the 5 - and 10-year overall survival of patients whose cancer of the uterine body only, and those who are diagnosed with a malignant tumor following - in those without a second tumor is 85.3% and 81.4 %, and in the presence of such a - 78, 6% and 69.3% respectively. Conclusion: The matched tumors are the most common among the so-called hormone dependent cancers such as breast cancer, uterine

    Endometrial biopsies are undertaken in premenopausal women with abnormal uterine bleeding but the risk of endometrial cancer or atypical hyperplasia is unclear. To conduct a systematic literature review to establish the risk of endometrial cancer and atypical hyperplasia in premenopausal women with abnormal uterine bleeding. Search of PubMed, Embase and the Cochrane Library from database inception to August 2015. Studies reporting rates of endometrial cancer and/or atypical hyperplasia in women with premenopausal abnormal uterine bleeding. Data were independently extracted by two reviewers and cross-checked. For each outcome, the risk and a 95% CI were estimated using logistic regression with robust standard errors to account for clustering by study. Sixty-five articles contributed to the analysis. Risk of endometrial cancer was 0.33% (95% CI 0.23-0.48%, n = 29 059; 97 cases) and risk of endometrial cancer or atypical hyperplasia was 1.31% (95% CI 0.96-1.80, n = 15 772; 207 cases). Risk of endometrial cancer was lower in women with heavy menstrual bleeding (HMB) (0.11%, 95% CI 0.04-0.32%, n = 8352; 9 cases) compared with inter-menstrual bleeding (IMB) (0.52%, 95% CI 0.23-1.16%, n = 3109; 14 cases). Of five studies reporting the rate of atypical hyperplasia in women with HMB, none identified any cases. The risk of endometrial cancer or atypical hyperplasia in premenopausal women with abnormal uterine bleeding is low. Premenopausal women with abnormal uterine bleeding should first undergo conventional medical management. Where this fails, the presence of IMB and older age may be indicators for further investigation. Further research into the risks associated with age and the cumulative risk of co-morbidities is needed. Contrary to practice, premenopausal women with heavy periods or inter-menstrual bleeding rarely require biopsy. © 2016 The Authors BJOG An International Journal of Obstetrics and Gynaecology published by John Wiley & Sons Ltd on behalf of Royal

    The purpose of this retrospective study was to evaluate the efficacy and feasibility of short-course hypofractionated radiotherapy (RT) for the palliation of uterine cervical cancer. Seventeen patients with cancer of the uterine cervix, who underwent palliative hypofractionated 3-dimensional conformal radiotherapy between January 2002 and June 2012, were retrospectively analyzed. RT was delivered to symptomatic lesions (both the primary mass and/or metastatic regional lymph nodes). The total dose was 20 to 25 Gy (median, 25 Gy) in 5 Gy daily fractions. The median follow-up duration was 12.2 months (range, 4 to 24 months). The median survival time was 7.8 months (range, 4 to 24 months). Vaginal bleeding was the most common presenting symptom followed by pelvic pain (9 patients). The overall response rates were 93.8% and 66.7% for vaginal bleeding control and pelvic pain, respectively. Nine patients did not have any acute side effects and 7 patients showed minor gastrointestinal toxicity. Only 1 patient had grade 3 diarrhea 1 week after completion of treatment, which was successfully treated conservatively. Late complications occurred in 4 patients; however, none of these were of grade 3 or higher severity. Short-course hypofractionated RT was effective and well tolerated as palliative treatment for uterine cervical cancer.

    Vaginal suppositories of Adriamycin (ADM, 5 mg), for reducing the capacity for repair from sublethal damage of X-ray-irradiated cells, were prepared using Wipepsol S-55 as the vehicle, and were intravaginally administered to patients with advanced uterine cervical cancer, and their pharmacokinetics and clinical effects were studied. The ADM concentration in the uterine cervical cancer tissues indicated high levels (17 to 566 μg/g), and migration into the cardinal ligament and regional lymph nodes was noted. However, little ADM was detected in serum (0 to 0.14 μg/g), probably because of its molecular weight and excellent tissue absorbance, and no side effects, such as cardiotoxicity and myelosuppression due to consecutive administration were detected. Histologically, the effect obtained when administered alone was limited, administration in combination with radiotherapy being more effective. Accordingly, radiotherapy of advanced uterine cervical cancer with concomitant administration of ADM vaginal suppositories seems to bring about a more powerful antitumoral effect with fewer systemic side effects.

Morcellation is often necessary to perform a laparoscopic surgery. The objective of this study is to determine the incidence of unexpected uterine sarcomas (UUSs after hysterectomy and myomectomy for uterine fibroids and to reduce the occurrence and avoid the morcellation of UUSs by analyzing their characteristics.Methods: Women who had a hysterectomy or myomectomy for uterine fibroids in Shengjing Hospital of China Medical University between November 2008 and November 2014 were selected for the study, and their clinical characteristics were analyzed.Results: During the period, 48 UUSs were found in 10,248 cases, and the overall incidence was 0.47%. There was no statistical difference (P=0.449 regarding the incidence (0.50% vs 0.33% between 42 UUSs in 8,456 cases undergoing laparotomy and six UUSs in 1,792 cases undergoing laparoscopy. Most of the UUSs were stage I (89.58%, which occurred more commonly (56.25% in women aged 40–49. Abnormal uterine bleeding (39.58% was the main clinical manifestation. Rapidly growing pelvic masses (12.5%, rich blood flow signals (18.75%, and degeneration of uterine fibroids (18.75% prompted by ultrasonography may suggest the possibility of UUSs. The margins of most UUSs (93.75% were regular, which may cause UUSs to be misdiagnosed as uterine fibroids. Fifteen cases underwent magnetic resonance imaging examinations. Approximately 73.33% showed heterogeneous and hypointense signal intensity on T1-weighted images, and 80% showed intermediate-to-high signal intensity on T2-weighted images, with necrosis and hemorrhage in 40% of cases. After contrast administration, 80% presented early heterogeneous

    Background. Due to specific war and post-war situation in Balkan region, differences in the number, type, development, biological course, treatment of malignant tumours and its outcome are possible. In order to perceive the situation realistically, it is necessary to gather continuously exact data about malignant tumours and compare them with the data from other European and world countries.The aim of the study was to collect and analyse the data on cancer incidence in the region of Sarajevo city, which represents a symbol of difficult times in the recent past, and to compare it to the incidence in the neighbouring countries. Patients and methods. Data on all newly diagnosed cancer cases, permanent residents of Sarajevo Canton, in the years 1999 and 2000 were collected. Crude incidence rate has been calculated according to the years observed, gender and localizations of the disease The data were compared to the cancer registries of Slovenia and Croatia and were observed in the light of specific local situation. Results. The crude cancer incidence of all sites but skin was the highest in both years and by both genders in Croatia. The incidence of the most common tumours (lung and breast cancer) was similar in all three countries. The differences in the incidence between both genders in the Sarajevo canton were registered in laryngeal and urinary bladder cancer, as well as in bone and cartilage sarcoma. Cervical cancer had extremely high incidence and was high up on the incidence list in the Sarajevo canton, which correlates with the data in developing countries. The incidence of other tumours in the post-war period is reaching expected numbers. Conclusions. It is difficult to identify whether the war and post-war stress, irregular and insufficient nutrition during and after the siege of the city of Sarajevo or some other factor influenced the cancer incidence among exposed population. The prevalence of smoking in the whole region is extremely high, in Bosnia and

    In Japan, radiotherapy with high dose rate remote after loading system (HDR-RALS) for intracavitary brachytherapy is the standard treatment for more than 30 years. This report showed the usefulness of HDR-RALS for uterine cervical cancer. From 1980 through 1999, 442 patients with uterine cervical cancers (stage I: 66, stage II: 161, stage III: 165, stage IV: 50) were treated. Radiotherapy was performed both external teletherapy and HDR-RALS. Overall survival rate at 5 years was 60.2%. The 5-year actuarial incidence of all complications was 16.4%. The 5-year actuarial incidence of all complications in cases treated with the sum doses of whole pelvic irradiation (without central shield) and RALS up to 49 Gy, 50 to 59 Gy or larger doses were 7.5%, 11.0% and 25.2%, respectively. Radiation therapy using HDR-RALS was very effective. While the dose of whole pelvic irradiation was increased, the actuarial incidence of all complications was increased. (author)

    Full Text Available Very limited information is available regarding the incidence of cancer in sub-Saharan Africa. We analyzed changes in cancer patterns from 1991 to 2008 in Maputo (Mozambique.We calculated the rates of incidence of different cancer sites by sex in the 5-year age-group of the population of Maputo city as well as age-standardized rates (ASRs and average annual percentage changes (AAPC.Over the 18-year study period a total of 12,674 cases of cancer (56.9% females were registered with an overall increase in the risk of cancer in both sexes. In males, the most common cancers were those of the prostate, Kaposi sarcoma (KS and the liver. Prostate cancer showed the most dramatic increase over the whole study period (AAPC +11.3%; 95% CI: 9.7-13.0, with an ASR of 61.7 per 105 in 2003-2008. In females, the most frequent cancers were of the uterine cervix, the breast and KS, with the former increasing along the whole study period (AAPC + 4.7%; 95% CI: 3.4-6 with an ASR of 62.0 per 105 in 2003-2008 as well as breast cancer (AAPC +6.5%; 95%CI: 4.3-8.7.Overall, the risk of cancer rose in both sexes during the study period, particularly among cancers associated with westernization of lifestyles (prostate, breast, combined with increasingly rising incidences or limited changes in cancers associated with infection and poverty (uterine cervix, liver. Moreover, the burden of AIDS-associated cancers has shown a marked increase.

    Cancers of the uterine cervix were classified for prediction of radiosensitivity. They were classified into two types: radioresistant type (R-type), in which the cancer was predominated by the properties of adenocarcinoma and was radioresistant, and radiosensitive type (S-type) in all others. In preoperatively irradiated cases of stage IIb cancer of uterine cervix, 84% of R-type cases showed viable cancer cells, and 84% of S-type cases showed tumor disappearance. In cases of radiotherapy in a period 1965 - 70, 69% of stage II cases and 70% of stage III cases of R-type showed disease progress; for S-type, 88% of stage II and 77% of stage III cases had tumor control. In stage III cases given radiotherapy alone in 1971 and 1972 after the histological features were examined, 82% of R-type cases showed tumor recurrence and 77% of S-type cases had disease control. Problems in the classification and assessment were discussed. (Chiba, N.)

    Whereas the local effect of radiotherapy in the postoperative treatment of uterine cervix cancer developing lymphogenic metastases may be regarded as clearly demonstrated, there is no evidence of its effect on the survival of patients. A definite answer to this question is only possible on the basis of prospective studies. In primary radiotherapy, more importance than in former days is given to percutaneous irradiation which allows a more homogeneous dose to the small pelvis. According to the present state of knowledge it is not justified to do without contact therapy except in cases of a very advanced disease. (orig.) [de

    High dose rate intracavitary irradiation for cancer of the uterine cervix was examined. The 5-year survival rate of this method showed no significant difference from that of the low dose rate intracavitary irradiation, nor did the onset of regional injury show any difference. The optimal dose for stage 1 and 2 was 2900 +- 300 rad, which was approx. 60% of that of the low dose rate method. Elevation of ESR affected the survival rate only in stage 3 and 4 cases. The 5-year survival rate of cases with normal kidney function was twice that of abnormal cases. Radiotherapy of cancer of uterine cervix produced a 5-year survival rate of 58.8% and a cancer morbidity rate of 33.1%; patients with metastasis cannot be cured. The basic form of dose distribution by intracavitary irradiation was tumbler of Manchester's technique. The radiation source was placed in accordance with the conditions established by this technique, and the dose distribution was corrected with a computer. (Chiba, N.)

    Uterine cervix carcinomas spread by direct local extension, lymphatic permeation and hematogenous dissemination. Their metastatic foci are closely related to iliopsoas compartment anatomically no matter what the pattern of spread is. Therefore, iliopsoas involvement in uterine cervix cancer may occur frequently. The authors reviewed pelvis CT of 218 cervix cancer patients for recent one year from March 1986 to February 1987 at Seoul National University Hospital. Among them, 10 cases showed iliopsoas involvement. Pattern of iliopsoas involvement was classified into four types: infiltrative type (three cases), localized mass type (three cases), mass with bone destruction type (two cases), paraaortic lymphadenopathy type (two cases). In all cases except 3 cases of infiltrative type, lymphadenopathy or bone metastasis adjacent to iliopsoas lesion was identified. And this finding suggested that the route of iliopsoas involvement in cervix cancer would be secondary infiltration from metastatic focus of adjacent lymph node or bone. Recognition of iliopsoas involvement of cervix caner may prevent misdiagnosis and predict the degree of disease dissemination

    Delayed postpartum haemorrhage due to uterine atony after caesarean section was occurring in women in our recovery area despite many of them already having an oxytocin infusion running to prevent such a problem. We therefore decided to compare the incidence of such problems for a 2-month period before and after altering our uterotonic policy: in addition to the routine bolus dose of 5 units of oxytocin after delivery of the baby, we added 500 microg of intramuscular ergometrine during abdominal closure. We noticed a reduced number of massive postpartum haemorrhages due to an atonic uterus in the recovery room but an increased incidence of nausea and vomiting. No prophylactic anti-emetic was given during this pilot study. This small study suggests that 50 women would need to be given ergometrine at caesarean section to prevent one delayed massive haemorrhage from uterine atony and four extra women would suffer with vomiting. We feel this is reasonable and now use a prophylactic anti-emetic as well as delaying the ergometrine until closure of the rectus sheath which reduces the incidence of nausea and vomiting.

    Skin cancer is the most frequent cancer related to ultraviolet radiation. The aim was to estimate the incidence of skin cancer type, melanoma and non-melanoma in Zacatecas, Mexico. An epidemiological study was carried out during the period from 2008 to 2012. The data were obtained from the Instituto Mexicano del Seguro Social (IMSS), Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE), Secretaría de Salud de Zacatecas (SSZ) and a private source, the Centro Médico Alameda. The incidence and the global prevalence were estimated. We studied 958 skin cancer cases, histopathologically confirmed. The cases were distributed as: 63.6 % basal cell carcinomas, 25.8 % squamous cell carcinomas, and 10.6 % melanoma. Significantly higher proportions were observed in women in the basal cell carcinomas (60.4 %) and squamous cell carcinomas (53.4 %). However, in the case of melanoma, the major proportion was observed in men (55.9 %). The more frequent skin cancer location was the face and for basal cell carcinoma was the nose (53 %); for squamous cell carcinomas were the lips (36 %), and for melanoma it was also the nose (40 %). The skin cancer incidence was estimated in 20 cases for each 100 000 inhabitants. Linear regression analysis showed that the skin cancer is increasing at an annual rate of 10.5 %. The anatomical location indicates that solar UV radiation is a risk factor, since the face is the zone with major exposure to solar radiation.

    Platelet-derived growth factor receptor α (PDGFRα) expression is frequently observed in many kinds of cancer and is a candidate for therapeutic targeting. This preclinical study evaluated the biologic significance of PDGFRα and PDGFRα blockade (using a fully humanized monoclonal antibody, 3G3) in uterine cancer. Expression of PDGFRα was examined in uterine cancer clinical samples and cell lines, and biologic effects of PDGFRα inhibition were evaluated using in vitro (cell viability, apoptosis, and invasion) and in vivo (orthotopic) models of uterine cancer. PDGFRα was highly expressed and activated in uterine cancer samples and cell lines. Treatment with 3G3 resulted in substantial inhibition of PDGFRα phosphorylation and of downstream signaling molecules AKT and mitogen-activated protein kinase (MAPK). Cell viability and invasive potential of uterine cancer cells were also inhibited by 3G3 treatment. In orthotopic mouse models of uterine cancer, 3G3 monotherapy had significant antitumor effects in the PDGFRα-positive models (Hec-1A, Ishikawa, Spec-2) but not in the PDGFRα-negative model (OVCA432). Greater therapeutic effects were observed for 3G3 in combination with chemotherapy than for either drug alone in the PDGFRα-positive models. The antitumor effects of therapy were related to increased apoptosis and decreased proliferation and angiogenesis. These findings identify PDGFRα as an attractive target for therapeutic development in uterine cancer. ©2014 American Association for Cancer Research.

Blokhin Russian Cancer Research Center from 1980 to 2000 is analyzed. Correlation of overall 5-year survival rates of stage IIA and IIB uterine can- cer patients with a number of tumor morphologic features is studied. The influence of some non-elucidated morphologic features of stage IIA and IIB uterine cancer such as the degree of cellular anaplasia, the depth of tumor invasion into the uterine neck, lymho- vascular invasion into the myometrium and uterine neck, microscopic vessels density in the area of the most extensive invasion, the presence of necrotic areas in the tumor tissue on long-term treatment results are analyzed.

    Background: Uterine cancer is a prevalent disease in Chile and it is one of the most frequent cancer locations treated in the National Chilean Cancer Institute. It is also common to receive young patients that have advanced tumors in stages IIB and IIIB with high risks of compromises of lymphatic nodes of pelvis and aortic-lumbar zones. The treatment for these kinds of cancers is radio-chemotherapy. Aims: Determinate if the radiotherapy of aortic-lumbar lymph nodes lowers the chance of relapsing or increase the survival rate in patients with evident compromise of aortic-lumbar lymph nodes and in those with high risk of compromise in that level. Method: Exhaustive analysis of the literature about the indication of radiotherapy of aortic-lumbar lymph nodes in cervix cancer which is classified in those where the radiotherapy treatment is done in patients with evident compromise of aortic-lumbar lymph-nodes, and those where de radiotherapy is done in patients with high risk of compromise in that level. Results: In patients with small cervix tumors and positive lymphoid nodes the LA lymphatic nodes treatment would be beneficial. However, patients that suffer massive pelvic disease (IIIB) or that have evidence of the disease, the benefit would not be so important. Conclusion: Patients with controllable pelvic disease and with high risk of having aortic-lumbar lymph nodes compromise are the most benefit of radiotherapy in aortic-lumbar lymph nodes (stages IA-B, IIA-B with positive lymph nodes)

    To assess the efficacy of the use of accelerated hyperfractionated radiotherapy (AHRT) for locally advanced uterine cervix cancers. Between May 2000 and September 2002, 179 patients were identified with FIGO stage IIB, IIIB, and IVA cancers. Of the 179 patients, 45 patients were treated with AHRT (AHRT group) and 134 patients were treated with conventional radiotherapy (CRT group), respectively. Patients undergoing the AHRT regimen received a dose of 30 Gy in 20 fractions (1.5 Gyx2 fractions/day) to the whole pelvis. Subsequently, with a midline block, we administered a parametrial boost with a dose of 20 Gy using 2 Gy fractions. Patients also received two courses of low-dose-rate brachytherapy, up to a total dose of 85∼90 Gy to point A. In the CRT group of patients, the total dose to point A was 85∼90 Gy. The overall treatment duration was a median of 37 and 66 days for patients that received AHRT and CRT, respectively. Statistical analysis was calculated by use of the Kaplan-Meier method, the log-rank test, and Chi-squared test. For patients that received cisplatin-based concurrent chemotherapy and radiotherapy, the local control rate at 5 years was 100% and 79.2% for the AHRT and CRT group of patients, respectively (p=0.028). The 5-year survival rate for patients with a stage IIB bulky tumor was 82.6% and 62.1% for the AHRT group and CRT group, respectively (p=0.040). There was no statistically significant difference for severe late toxicity between the two groups (p=0.561). In this study, we observed that treatment with AHRT with concurrent chemotherapy allows a significant advantage of local control and survival for locally advanced uterine cervix cancers

    Purpose: In patients with uterine cervical cancer, pretreatment recognition of uterine extension is crucial in treatment decision-making for fertility-sparing surgery and for target delineation in radiotherapy. Although MRI is generally considered the most reliable method, its value for detecting involvement of the uterine internal os is unclear. Methods: Medline, Embase and Cochrane databases were systematically searched (January 1997–December 2012) for MRI studies that measured the accuracy of involvement of the uterine internal os compared to histopathology as reference standard in patients with uterine cervical cancer. Data were assessed using the QUADAS tool. Accuracy concerned either involvement (yes/no) of the uterine internal os, or measuring invasion distance toward the uterine corpus. Results: Two retrospective and two prospective studies described 366 patients diagnosed with uterine cervical cancer FIGO stage IIB or below, in whom 64 (17%) had uterine internal os involvement. For three studies the summary estimates of specificity, sensitivity, negative predictive value (NPV), positive predictive value (PPV), and accuracy were 91%, 97%, 99%, 79% and 95%, respectively; one study had an area under the curve (AUC) of 0.8. Conclusion: MRI has a high level of accuracy; however, data are limited and for validation a large prospective study is needed that compares actual measurements on MRI with histopathological examination.

    The author presents the five-year healing results of 4347 uterine cervix cancers treated at our Radiotherapeutic Institute within the years of 1928 to 1977. The part of patients irradiated postoperatively increased by 30% during this period, and the average age of patients at the beginning of their disease increased by almost seven years. The overall five-year healing results increased from 47 to 60% during this half of a century, especially the prognosis of stage II and III was considerably improved. With almost the same rate of radiogenic side effects, the incidence of recurrences could be reduced by 50%. The healing results achieved by us in uterine cervix cancer during the last ten years under report correspond well with the healing results of other radiotherapeutic hospitals. Even when compared to the most recent reports on the success achieved by afterloading techniques, there is not much difference to our recent results obtained with radium brachytherapy. (orig.) [de

    The effects of 1000 R of tele-cobalt upon the changes in the primary lesions of uterine cervical cancer with time were studied with an electron microscope. In addition, twenty cases which were proven to have cancer tissues (10 cases of IInd stage of cancer, 8 cases of IIIrd stage of cancer and 2 cases of IVth stage of cancer) were studied. Four cases were favourably sensitive, 7 cases moderately sensitive and 9 cases unfavourably sensitive to radiation. In favourably radio-sensitive cases, the changes in the cancer cells first appeared in the nucleus. There were other changes such as local clumping of chromatin and, specifically, vacuolization of the nucleus. The changes in the endoplasmic reticulum appeared somewhat late. In addition, the disturbance of mitochondria and the decrease or disappearance of ribosomes were specifically due to radiation injury. From the point of view of changes with time, Golgi's apparatus was enlarged and the membrane of the endoplasmic reticulum was degenerated at the 1st day. At the 3rd day, vacuolization of the nucleus appeared, the nuclear corpuscles were increased, the nucleoplasm became thin, and mitochondria was enlarged and degenerated. At the 5th day, the nuclear membrane disappeared, the nucleus was destroyed, large vacuolization of the endoplasmic reticulum was seen, free ribosomes were decreased, and changes around the endoplasmic reticulum were observed. At the 7th day, collagen around the endoplasmic reticulum appeared. In favourably radiosensitive cases, individual tumor cells showed the same degeneration, which fairly corresponded to that evaluated by the histological observation. The disturbance of the cells was caused by radiation, so-called ''burning'' of the cells. Radiation protection of the cells against burning was considered in terms of their radiosensitivity.

    Okabayashi's extensive panhysterectomy is used for cancer of uterine cervix in Japan, and the rate of its practice was 45.6% at the National Cancer Center (1962 - 73, stage 1 - 4 cases). Cancer death within 5 years occurred in 92.3% of the total deaths, and the total surgical deaths did not exceed 1%. Postoperative irradiation was performed in cases with lymph node metastasis, those with parametrial invasion and those with deep primary lesions. Intravaginal irradiation was sometimes performed in cases of insufficient vaginal excision. Therefore, the 5-year survival rate of postoperatively irradiated cases was 71.4%, and that of non-irradiated cases 93.7%. The 5-year survival rate of all cases of adenocarcinoma including irradiated cases was 44.7%. Since the effect of irradiation was not so promising, postoperative irradiation with fast neutrons is performed in adenocarcinoma cases with metastasis and/or infiltration. Effect of combination with chemotherapy has been poor. The indication of less surgery for early cases is under examination. (Chiba, N.)

    Standardized incidence ratio for cancer in Norwegian Seventh-Day Adventists compared with the general population was not significantly different from unity (men 91, women 97). Persons converting late in life had a higher incidence than those converting at an earlier age. Respiratory cancers (standardized incidence ratio [SIR] 59, 95% CI = 36 to 91) and cancers with an unspecified site (SIR 53, 95% CI = 25 to 97) were rarer and cancer of the uterine corpus (SIR 164, 95% CI = 109 to 237) was more common in Seventh-Day Adventists before the age of 75 years. Inclusion of all registered Seventh-Day Adventists regardless of religious activity and the relatively low cancer incidence rates in the Norwegian population could contribute to the nonsignificant result with regard to total cancer. Main etiologic factors in cancer development in Norway should be sought in areas where Seventh-Day Adventists do not differ from the general population.

    To improve the quality of radiation oncology in Japan, a Patterns of Care Study (PCS), a quality assurance program widely known in the United States, was introduced to Japan. In this study, the process, including work-up and treatment for uterine cervix cancer patients, was investigated to show nationwide variation by age. From July 1996 through February 1997, PCS extramural audits were performed for 29 institutions nationwide. Medical charts for 432 patients with uterine cervix cancer treated between 1992 and 1994 were reviewed based on the PCS data format used in the US. The processes of radiation therapy for these patients were compared in two age groups those aged ≥75 years (n=132) and those aged <75 years (n=300). There were significant differences by age group in medical background, indicating the fragility of the elderly and a relatively higher incidence of early-stage disease in the elderly by patient selection. Lower pelvic radiation doses were used for the elderly with advanced stage disease. There were no significant differences in unplanned breaks in external irradiation between the two age groups. Brachytherapy was used less commonly in the elderly group than in younger group (p=0.0187). The dose range for brachytherapy did not show any significant difference between the two groups. Preliminary survival rates for the elderly were similar to those for the younger group. Radiation therapy was found to play an important role in the treatment of uterine cervix cancer in elderly as well as younger patients. (author)

    Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb.

    Patients who have undergone pelvic irradiation are reported to be at an increased risk of subsequently developing malignancies of the pelvic organs. We report a case of multiple cancers in the pelvic organs after radiation therapy for uterine cancer. The patient was a 76-year-old woman who had undergone a hysterectomy with radiation therapy for uterine cancer in 1960. Thereafter, she had undergone a total cystectomy for bladder cancer in 1989; an abdominoperineal resection for rectal cancer with radiation proctitis in February 1991; and a right hemicolectomy for cecum cancer in 1995. Then, in 2005, she was found to have early cancer of the sigmoid colon at the stoma, so that the colon was dissected from the periphery of the stoma, the sigmoid colon was removed, and an artificial anus was reconstructed again. The histopathological diagnosis was early well-differentiated adenocarcinoma. She had undergone three operations for multiple cancers of the large intestine in the pelvis at different times during 16 years since 1989 when the bladder cancer was detected and surgically treated. And she has been alive and well. Long-term follow-up would be mandatory for such patients undergone pelvic irradiation who might be able to survive for a long time with appropriate therapies like this patient. (author)

    assumption of future stabilization in the prevalence of screening. New cancer cases to rise: The annual number of new cancer cases is predicted to increase by 84% in Canadian males, from 80 800 in 2003-2007 to 148 400 in 2028-2032, and by 74% in Canadian females, from 74 200 to 128 800. Drivers of the changes in cancer cases: The primary reason for the increase in the number of all newly diagnosed cancer cases will be the aging of the Canadian population and, to a lesser extent, the increase in population size. Changes in the risk of cancer will constitute a relatively small component of the projected increase in new cases. Preventive interventions can have a strong influence on future incidence rates for individual cancer types. Most common cancers: The most common new cancers in males--prostate, colorectal, lung and bladder cancers, and non-Hodgkin lymphoma--are projected to remain the same from 2003-2007 to 2028-2032, but colorectal cancer is predicted to outrank lung cancer as the second most frequently diagnosed cancer by 2028-2032. For females, breast, lung, colorectal and uterine cancers figure as the top 4 most common incident cancers in both periods. However, thyroid cancer will overtake non-Hodgkin lymphoma as the fifth most common cancer by 2028-2032. Incidence by geographical region: There is an east-west gradient in incidence across Canada. The highest incidence rates for most cancers are projected to be in eastern Canada (Atlantic region [New Brunswick, Prince Edward Island, Nova Scotia, and Newfoundland and Labrador], Quebec or Ontario for both males and females. While British Columbia is projected to continue to have the lowest incidence rates for the majority of cancers in both sexes, this province will also continue to experience the highest rates for esophageal cancer in females, liver cancer in both sexes and testis cancer. The Atlantic region is projected to have the lowest incidence rates for cancers of the breast, uterus and ovary in females, and for

    Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine. Based on the difficulties of cytopathologic evaluation for the follow-up of patients treated with radiotherapy for cervical cancer, our objective was to describe the actinic cytopathic effects. Our paper was based on a structured review including the period from June 2015 to April 2016, aiming at an exploratory-descriptive study. Bibliographic investigations were carried out through selection and analysis of articles, list of authors and keywords, selection of new articles focused on the analysis of bibliographic references to previously selected documents, as well as textbooks of recognized merit. The most incident actinic cytopathological alterations as described in the literature are: cellular gigantism, nuclear and cytoplasmic vacuolization, dyskeratosis, bi- and multinucleated (B/M) cells, macro and multiple nucleoli, anisokaryosis, anisonucleolosis and nuclear pyknosis. To date, a protocol has not been established that can precisely differentiate the morphological characteristics between benign cells with actinic effects from recurrent malignant cells on post-radiotherapy smears.

    152 patients with advanced uterine cervical cancer (76 in stage III, 47 in stage IV and 29 in recurrence) were treated at Miyagi Seijinbyo Center in fifteen years (1967-1981). Our standard treatment was a combined therapy of 6 MVX ray whole pelvis irradiation and intracavitary radium irradiation (or simple total hysterectomy) The actuarial 5-year-survival rate was 46.0% in stage III, 9.4% in stage IV and 10.3% in recurrence. In stage III, the actuarial 5-year-survival rate in nine cases with external irradiation alone was (22.2%), in 44 cases with intracavitary irradiation and external irradiation 48.7%; in 14 cases with operation and external irradiation 57.1%. No five year survival was found in nine interrupted-irradation cases. Moderate complications in the rectum and/or the urinary bladder were found in eight of 67 (12%) irradiation-completed patients in stage III. Five 5-year-survival cases (two in stage IV and three in recurrence) were reported. (author)

    Protease activated receptor-2 (PAR-2) has been implicated in cellular proliferation, invasion and metastasis in various tumors. Lymph node metastasis is an important patient prognostic factor for uterine cervical cancers. This prompted us to study the role of PAR-2 in lymph node metastasis of uterine cervical cancers. Thirty patients underwent surgery for uterine cervical cancers. PAR-2 histoscores and mRNA levels were determined by immunohistochemistry and real-time reverse transcription-polymerase chain reaction, respectively. Patient prognosis was analyzed with a 48-month survival rate. PAR-2 histoscores and mRNA levels significantly (P < 0.05) increased in 12 of 30 metastatic lymph node lesions from the corresponding primary tumor. The 48-month survival rate of the 12 patients with increased PAR-2 levels in metastatic lymph nodes was 42%, while the rate of the other 18 patients with no change in PAR-2 levels was 82%, regardless of histopathological type. PAR-2 might work on lymph node metastasis of uterine cervical cancers, and is considered to be a novel prognostic indicator for uterine cervical cancers

    This study was conducted to evaluate the treatment results, prognostic factors, and complication rates after high dose rate (HDR) brachytherapy in patients with uterine cervix cancer who were treated with curative aim. Of 269 cervix cancer patients treated at the department of radiation oncology, Samsung Medical Center from September 1994 to July 1998, the 106 who were treated with radical radiotherapy were analyzed. The median age was 61 years (range 22 to 89). All patients except 4 with carcinoma in situ (CIS) were given external beam radiotherapy (range 30.6 {approx} 50.4 Gy to whole pelvis) and HDR brachytherapy. The common regimens of HDR brachytherapy were a total dose of 24 {approx} 28 Gy with 6 {approx} 7 fractions to point A at two fractions per week. The median overall treatment time was 55 days (range 44 to 104) in patients given both external beam radiotherapy and HDR brachytherapy. Early response of radiotherapy were evaluated by gynecologic examination and follow-up MRI 1 month after radiotherapy. Treatment responses were complete remission in 72 patients, partial response in 33 and no response in 1. The overall survival (OS) rate of all patients was 82%, and 73%, and the disease free survival (DFS) rate was 72%, and 69%, at 3, and 5 years, respectively. The pelvic control rate (PCR) was 79% at both 3 and 5 years. According to the FIGO stage, 3 and 5 year OS were 100% and 50% in CIS/IA, 100% in 100% in IB, 83% and 69% in IIA, 87% and 80% in IIB, and 62% and 62% in III, respectively. The 3 year OS in 4 patients with stage IVA was 100%. Three-year DFS were 80% in CIS/IA, 88% in IB, 100% in IIA, 64% in IIB, 58% in III, and 75% in IVA. Three-year PCR were 100% in CIS/IA, 94% in IB, 100% in IIA, 84% in IIB, 69% in III, and 50% in IVA. By univariate analysis, FIGO stage and treatment response were significant factors for OS. The significant factors for DFS were age, FIGO stage, treatment response and overall treatment time (OTT). For pelvic control rate

    Objective: To evaluate super-selective uterine arterial chemoembolization therapy in the treatment of cervical cancer. Methods: Bilateral uterine arterial infusion with DDP, EADM or THP, MMC and 5-Fu was performed in 56 patients with pathologically-proved cervical cancer, which was followed by embolization of uterine arteries with iodine emulsion and Gelfoam particles. Radical hysterectomy was performed in 6 patients after interventional treatment. Results: Embolization of bilateral uterine arteries were successfully carried out in all cases. The angiography conducted during the procedure revealed markedly dilated uterine arteries, spiral tumor-feeding arteries and obvious tumor staining. The total effective rate was up to 94.6%. Six patients received radical hysterectomy 2 weeks after arterial chemoembolization, and the blood loss during the operation was much less than usual and the surgery procedure took shorter time. Ovarian necrosis was found in 1 case. The main adverse effects included leukocytopenia, nausea, vomiting and abdominal pain. Conclusion: Super-selective uterine arterial chemoembolization is a safe and effective supplementary therapy for cervical carcinoma with fewer complications. (authors)

    Purpose of the radio-therapy is maximize the radiation dose to the tumor while minimizing the dose to the critical organ. Carcinoma of the uterine cervix treatment are external irradiation or an interstitial brachytherapy make use of isotope. Brachytherapy is a method of radiotherapy in advantage to achieve better local control with minimum radiation toxicity in comparison with external irradiation because radiation dose is distributed according to the inverse square low of gamma-ray emitted from the implanted sources. Authors make use of the patients data which 192 Ir gives medical treatment intracavity. Intracavitary radiation of the uterine cervix cancer, critical organ take 20% below than exposure dose of A point in the ICRU report. None the less of the advice, Radiation proctitis and radiation cystitis are frequent and problematic early complications in patients treated with radiation for the uterine cervix cancer. In brachytherapy of uterine cervical cancer using a high dose rate remote afterloading system, it is of prime importance to deliver a accurate dose in each fractionated treatment by minimizing the difference between the pre-treatment planned and post-treatment calculated doses. Use of packing to reduce late complications intracavitary radiation of the uterine cervix cancer. Bladder and rectum changes exposure dose rate by radiotherapy make use of packing.

    To design clear guidelines for the staging and follow-up of patients with uterine cervical cancer, and to provide the radiologist with a framework for use in multidisciplinary conferences. Methods: Guidelines for uterine cervical cancer staging and follow-up were defined by the female imaging subcommittee of the ESUR (European Society of Urogenital Radiology) based on the expert consensus of imaging protocols of 11 leading institutions and a critical review of the literature. The results indicated that high field Magnetic Resonance Imaging (MRI) should include at least two T2-weighted sequences in sagittal, axial oblique or coronal oblique orientation (short and long axis of the uterine cervix) of the pelvic content. Axial T1-weighted sequence is useful to detect suspicious pelvic and abdominal lymph nodes, and images from symphysis to the left renal vein are required. The intravenous administration of Gadolinium-chelates is optional but is often required for small lesions (<2 cm) and for follow-up after treatment. Diffusion-weighted sequences are optional but are recommended to help evaluate lymph nodes and to detect a residual lesion after chemoradiotherapy. Expert consensus and literature review lead to an optimized MRI protocol to stage uterine cervical cancer. MRI is the imaging modality of choice for preoperative staging and follow-up in patients with uterine cervical cancer. (orig.)

    To prove the usefulness of magnetic resonance imaging (MRI) in determining the invasion of uterine cervical cancer with imaging planes, we evaluated 44 patients with histologically proved cervical cancer. MRI was performed with a Signa 1.5 T (General Electric), and a T 2 -weighted image was used. In coronal planes, the accuracy was 75.0% for parametrial invasion. It was impossible to diagnose in 77.8%, 92.1% and 63.2% the invasion of the uterine body, bladder, and rectum, respectively. In axial planes, the accuracy was 76.3%, 92.1% and 78.9% for the invasion of parametrium, bladder and rectum, respectively. It was impossible to diagnose in 72.2% the invasion of the uterine body. In sagittal planes, the accuracy was 80.6%, 97.4% and 89.7% for invasion of the uterine body, bladder and rectum, respectively. In all 39 cases it was impossible to diagnose parametrial invasion. In five cases, MRI failed to detect the tumor in any of the three planes, but in three cases it was able to detect the tumor in at least one of the three. We conclude as follows: MRI is a useful method in determining the invasion of cervical cancer. Coronal planes are recommended for the determination of parametrial invasion, axial planes for the parametrium, bladder and rectum, and sagittal planes for the uterine body, bladder and rectum. All three planes are needed to determine cervical cancer. (author)

    Full Text Available The clinical case of seldom found pathology – primary cancer of the uterine tube including at the same time both epithelial and sarcomatous component of a tumor is described. Data on a cancer of a uterine tube which, being a rare tumor are submitted, is morphologically similar to an ovary carcinoma. Predictively significant factors for this tumor are the disease stage, volume of residual tumoral masses, SA-125 indicators, and also as those the vascular invasion, degree of a differentiation of a tumor and age of patients are considered. On the basis of our supervision and clinical experience we came to a conclusion that this clinical case emphasizes not specificity of a current and complexity of timely diagnosis of a disease. Thus, an actual task is research of this problem for the purpose of improvement of quality of early diagnosis of primary cancer of uterine tube and use of new modern methods of treatment.

The patients were performed hepatography (44 of them - dynamic liver scintigraphy with Tc 99m - mezida) before the treatment, immediately after and 1-1.5 and 2-3 years after the course of radiotherapy. Latent disturbance of hepatobiliary system function which can be revealed with radionuclide study is shown to be observed in the patients with uterine cancer before the treatment. The level of hepatocytes functioning after the treatment depends largely on their initial functional state. Computer assisted multichannel radiography with evaluation of effective blood flow in the liver and effective fraction of minute volume of the blood flow is the most reasonable for monitoring hepatocytes function during treatment in the patients with uterine cancer

    Introduction The sentinel node technique (S.N.) was proposed in cervical cancers in order to optimise the diagnosis of metastases and the lymphatic micrometastases in the early stages while avoiding useless wide clearings out. The identification of this node is done by injection of a dye and/or a radioactive colloid and its ablation for pathological examination. Patients and methods We report the case of three patients followed for a uterine cancer having benefited from a lymphoscintigraphy before surgery. During the surgical procedure, the detection of the sentinel node was carried out after cervical injection of blue dye and using a gamma detection probe. Results The lymphoscintigraphy was positive for two cases with a positive detection for the three cases during the operation. The pathological study revealed a node metastasis for one case. The technical of the sentinel node applied to uterine cancers appears realizable essentially for uterine cancers of early stage (I). However the risk of false negative can be observed in advanced cancer (III), as it is the case of our patient having a negative lymphoscintigraphy. Conclusion The nuclear medicine is important in the detection of the sentinel node of various cancers, uterine cancer included, thus allowing an appropriate cardiologic management. (authors)

    We calculated age-adjusted incidence rates per 100,000 by religion (Mormon, non-Mormon) for Utah (United States) using the 49,182 cancer cases occurring between 1971-85. For all causes of cancer, the rate in Utah for male members of the Church of Jesus Christ of Latter-day Saints (LDS or Mormons) was about 24 percent less than the comparable US rate. There was a 50-percent lower rate of cancers associated with cigarette smoking among LDS men. Non-LDS (NLDS) men in Utah experienced an incidence of smoking-associated cancers slightly higher than other US men. LDS men had an incidence of those cancers not associated with smoking slightly lower than US men, and NLDS men had a 40-percent higher rate than US men because of higher rates of melanoma and cancers of the lip and prostate gland. LDS women had an all-sites cancer rate 24 percent below the comparable US rate, and a 60-percent lower rate of smoking-associated cancers. The incidence of cancer not associated with smoking was 20 percent lower for LDS women compared with US women and was the result of lower rates of cancers of the colon, breast, and uterine cervix. NLDS women had a 13-percent higher incidence of cancers not associated with smoking because of higher rates of cancers of the lip and breast.

  17. Has the incidence of radiation-induced bowel damage following treatment of uterine carcinoma changed in the last 20 years

    1986-01-01

    Radiation-induced bowel damage occurred in 4.3% of patients treated primarily by irradiation for uterine carcinoma during the period 1962-1982. There has been a progressive rise in the incidence of radiation damage and radiation-induced rectovaginal fistula during this 20-year period. Radiation from intracavitary sources was a contributory factor in 92% of injured cases. The rising incidence of bowel damage in our patients may be due to an increase in the number of patients receiving a high rectal dose from the intracavitary source. There was a significantly (P<0.01) higher incidence of radiation injury in cases of cervical carcinoma compared to endometrical carcinoma. This was because cervical carcinoma tended to present at a more advanced stage than endometrial carcinoma and was more frequently treated with combined external and intracavitary irradiation. There was no significant increase in the incidence of complications among patients undergoing hysterectomy. (author)

  18. Increase of Prostate Cancer Incidence in Martinique

    Full Text Available Prostate cancer incidence is steadily increasing in many developed countries. Because insular populations present unique ethnic, geographical, and environmental characteristics, we analyzed the evolution of prostate cancer age-adjusted world standardized incidence rates in Martinique in comparison with that of metropolitan France. We also compared prostate cancer incidence rates, and lifestyle-related and socioeconomic markers such as life expectancy, dietary energy, and fat supply and consumption, with those in other Caribbean islands, France, UK, Sweden, and USA. The incidence rate of prostate cancer in Martinique is one of the highest reported worldwide; it is continuously growing since 1985 in an exponential mode, and despite a similar screening detection process and lifestyle-related behaviour, it is constantly at a higher level than in metropolitan France. However, Caribbean populations that are genetically close to that of Martinique have generally much lower incidence of prostate cancer. We found no correlation between prostate cancer incidence rates, life expectancy, and diet westernization. Since the Caribbean African descent-associated genetic susceptibility factor would have remained constant during the 1980–2005, we suggest that in Martinique some environmental change including the intensive use of carcinogenic organochlorine pesticides might have occurred as key determinant of the persisting highly growing incidence of prostate cancer.

    Aim: In many countries, the age-specific pattern of cervical cancer incidence is currently bipolar with peaks at for instance 45 and 65 years of age. Consequently, a large proportion of cervical cancer cases are presently diagnosed in women above the screening age. The purpose of the study...... was to determine whether this bipolar pattern in age-specific incidence of cervical cancer reflects underlying biology or can be explained by the fact that the data come from birth cohorts with different screening histories. Methods: Combination of historical data on cervical screening and population-based cancer...... incidence data from Denmark 1943–2013, Finland and Norway 1953–2013, and Sweden 1958–2013. Results: Since the implementation of screening, the incidence of cervical cancer has decreased for each successive birth cohort. All birth cohorts showed a unipolar age-specific pattern. In unscreened women in Denmark...

    National Central Cancer Registry of China (NCCRC) updated nationwide statistics of cancer incidence and mortality in China using population-based cancer registration data in 2013 from all available cancer registries. In 2016, 255 registries' data were qualified and included in this analysis. We estimated numbers of new cancer cases and deaths in China in 2013 using age-specific rates and corresponding national population stratified by area, sex, age group (0, 1-4, 5-9, 10-14…85+) and cancer type. The world Segi's population was applied for age-standardized rates. All rates were expressed per 100,000 person-year. A total of 3,682,000 new cancer cases and 2,229,300 cancer deaths were estimated in China in 2013. Cancers of lung, female breast, stomach, liver, colon-rectum and esophagus were the most common cancers, accounting for about half of all cancer new cases. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer were the five leading causes of cancer death, accounting for about 60% of all cancer deaths. The cancer patterns showed differences not only between male and female, but also among different geographic regions in China. For overall cancers, the age-standardized incidence rates were stable during the past decades in male, but significantly increased by 2.2% per year in female. Cancer poses a major threat to public health and the cancer burden keep raising in China. The annual updated cancer statistics can provide scientific basis for cancer prevention and control.

  1. Cytopathologic evaluation of patients submitted to radiotherapy for uterine cervix cancer

    Directory of Open Access Journals (Sweden)

    Cátia Martins Leite Padilha

    Full Text Available Summary Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine. Based on the difficulties of cytopathologic evaluation for the follow-up of patients treated with radiotherapy for cervical cancer, our objective was to describe the actinic cytopathic effects. Our paper was based on a structured review including the period from June 2015 to April 2016, aiming at an exploratory-descriptive study. Bibliographic investigations were carried out through selection and analysis of articles, list of authors and keywords, selection of new articles focused on the analysis of bibliographic references to previously selected documents, as well as textbooks of recognized merit. The most incident actinic cytopathological alterations as described in the literature are: cellular gigantism, nuclear and cytoplasmic vacuolization, dyskeratosis, bi- and multinucleated (B/M cells, macro and multiple nucleoli, anisokaryosis, anisonucleolosis and nuclear pyknosis. To date, a protocol has not been established that can precisely differentiate the morphological characteristics between benign cells with actinic effects from recurrent malignant cells on post-radiotherapy smears.

    Some epidemiologic studies have indicated that uterine cancer risk may be increased after use of fertility drugs. To further assess this association, the authors used data from a large cohort of 54,362 women diagnosed with infertility who were referred to Danish fertility clinics between 1965 and 1998. In a case-cohort study, rate ratios and 95% confidence intervals were used to assess the effects of 4 groups of fertility drugs on overall risk of uterine cancer after adjustment for potentially confounding factors. Through mid-2006, 83 uterine cancers were identified. Ever use of any fertility drug was not associated with uterine cancer risk (rate ratio (RR) = 1.10, 95% confidence interval (CI): 0.69, 1.76). However, ever use of gonadotropins (follicle-stimulating hormone and human menopausal gonadotropin) increased uterine cancer risk (RR = 2.21, 95% CI: 1.08, 4.50); the risk was primarily observed after 10 years of follow-up. Furthermore, uterine cancer risk increased with number of cycles of use for clomiphene (for > or =6 cycles, RR = 1.96, 95% CI: 1.03, 3.72) and human chorionic gonadotropin (for > or =6 cycles, RR = 2.18, 95% CI: 1.16, 4.08) but not for other gonadotropins. Use of gonadotropin-releasing hormone analogs was not associated with risk. Gonadotropins, and possibly clomiphene and human chorionic gonadotropin, may increase the risk of uterine cancer, with higher doses and longer follow-up leading to greater risk.

    Many case reports have suggested an association between Klinefelter syndrome (KS) and cancer, but studies of the cancer incidence in larger groups of men with KS are lacking. A cohort of 696 men with KS was established from the Danish Cytogenetic Register. Information on the cancer incidence in the cohort was obtained from the Danish Cancer Registry and compared with the expected number calculated from the age, period and site specific cancer rates for Danish men. A total of 39 neoplasms were diagnosed (relative risk = 1.1). Four mediastinal tumours were observed (relative risk = 67); all four were malignant germ cell tumours. No cases of breast cancer or testis cancer were observed. One case of prostate cancer occurred within a previously irradiated field. No excess of leukaemia or lymphoma was found. An increased risk of cancer occurred in the age group 15-30 years (relative risk = 2.7). All six tumours in this group were germ cell tumours or sarcomas. The overall cancer incidence is not increased and no routine cancer screening seems to be justified. A considerably elevated risk of mediastinal germ cell tumours occurs in the period from early adolescence until the age of 30. PMID:7841064

    Full Text Available INTRODUCTION. The incidence of cancer among residents in sites contaminated by pollutants with a possible health impact is not adequately studied. In Italy, SENTIERI Project (Epidemiological study of residents in National Priority Contaminated Sites, NPCSs was implemented to study major health outcomes for residents in 44 NPCSs. METHODS. The Italian Association of Cancer Registries (AIRTUM records cancer incidence in 23 NPCSs. For each NPCSs, the incidence of all malignant cancers combined and 35 cancer sites (coded according to ICD-10, was analysed (1996-2005. The observed cases were compared to the expected based on age (5-year period,18 classes, gender, calendar period (1996-2000; 2001-2005, geographical area (North-Centre and Centre-South and cancer sites specific rates. Standardized Incidence Ratios (SIR with 90% Confidence Intervals were computed. RESULTS. In both genders an excess was observed for overall cancer incidence (9% in men and 7% in women as well as for specific cancer sites (colon and rectum, liver, gallbladder, pancreas, lung, skin melanoma, bladder and Non Hodgkin lymphoma. Deficits were observed for gastric cancer in both genders, chronic lymphoid leukemia (men, malignant thyroid neoplasms, corpus uteri and connective and soft-tissue tumours and sarcomas (women. DISCUSSION. This report is, to our knowledge, the first one on cancer risk of residents in NPCSs. The study, although not aiming to estimate the cancer burden attributable to the environment as compared to occupation or life-style, supports the credibility of an etiologic role of environmental exposures in contaminated sites. Ongoing analyses focus on the interpretation of risk factors for excesses of specific cancer types overall and in specific NPCSs in relation to the presence of carcinogenic pollutants.

    Airline cabin crew are occupationally exposed to cosmic radiation and jet lag with potential disruption of circadian rhythms. This study assesses the influence of work-related factors in cancer incidence of cabin crew members. A cohort of 8,507 female and 1,559 male airline cabin attendants from Finland, Iceland, Norway and Sweden was followed for cancer incidence for a mean follow-up time of 23.6 years through the national cancer registries. Standardized incidence ratios (SIRs) were defined as ratios of observed and expected numbers of cases. A case-control study nested in the cohort (excluding Norway) was conducted to assess the relation between the estimated cumulative cosmic radiation dose and cumulative number of flights crossing six time zones (indicator of circadian disruption) and cancer risk. Analysis of breast cancer was adjusted for parity and age at first live birth. Among female cabin crew, a significantly increased incidence was observed for breast cancer [SIR 1.50, 95% confidence interval (95% CI) 1.32-1.69], leukemia (1.89, 95% CI 1.03-3.17) and skin melanoma (1.85, 95% CI 1.41-2.38). Among men, significant excesses in skin melanoma (3.00, 95% CI 1.78-4.74), nonmelanoma skin cancer (2.47, 95% CI 1.18-4.53), Kaposi sarcoma (86.0, 95% CI 41.2-158) and alcohol-related cancers (combined SIR 3.12, 95% CI 1.95-4.72) were found. This large study with complete follow-up and comprehensive cancer incidence data shows an increased incidence of several cancers, but according to the case-control analysis, excesses appear not to be related to the cosmic radiation or circadian disruptions from crossing multiple time zones.

    The peculiarities of immunological reactivity in uterine and cervical cancer was studied. The study involved 94 patients who were administered combination radiation therapy for the above cancer. Before the treatment, the investigated group of the patients was characterized by the changes in a number of parameters of immunological reactivity (increased IgG, IgA, IgM serum concentrations, reduction of CD3+ and CD4+ amount, increased expression of CD95). The majority of changes were noticed immediately after the radiation therapy. Three and six month later the majority of immunological reactivity parameters did not differ from the respective values in the healthy group. Investigation of immunological reactivity in patients with uterine and cervical cancer allows to choose adequate treatment for this group of patients and improve its efficacy

    In Mexico, a woman dies of cervical-uterine cancer every 2 hours, indicating a low impact by the national program for early detection of this cancer, principally because of problems related to quality and coverage. Through a qualitative study, we identified the principal barriers to use of the detection program from the point of view of actual and potential program users. Four focus groups were organized in standard conditions in Mexico City (urban, developed) and in the southern state of Oaxaca (rural, economically disadvantaged area). Participants were either women with at least one previous Papanicolaou (Pap) test or women who had never had the test. Barriers to Pap test use included (1) lack of knowledge about cervical-uterine cancer etiology, (2) not knowing that the Pap test exists, (3) the conception that cancer is an inevitably fatal disease, (4) problems in doctor/medical institution-patient relationships, (5) giving priority to unmet needs related to extreme poverty, (6) opposition by the male sexual partner, (7) rejection of the pelvic examination, (8) long waits for sample collection and receiving results, and (9) perceived high costs for care. To increase coverage of the early detection program for cervical-uterine cancer in Mexico, the needs, perceptions, and beliefs of women and their partners must be taken into account when developing policy and planning, given the role these factors play in the decision-making process that leads to their participation or nonparticipation in this program.

    Background Testicular cancer is a rare tumor type accounting for 1% of malignancies in men. It is, however, the most common cancer in young men in Western populations. The incidence of testicular cancer is increasing globally, although a decline in mortality rates has been reported in Western countries. It is important to identify whether the variations in trends observed between populations are linked to genetic or environmental factors. Methods Age-standardized incidence rates and age-standardized mortality rates for testicular cancer were obtained for men of all ages in ten countries from the Americas, Asia, Europe, and Oceania using the Cancer Incidence in Five Continents (CI5plus) and World Health Organization (WHO) mortality databases. The annual percent change was calculated using Joinpoint regression to assess temporal changes between geographical regions. Results Testicular cancer age-standardized incidence rates are highest in New Zealand (7.8), UK (6.3), Australia (6.1), Sweden (5.6), USA (5.2), Poland (4.9), and Spain (3.8) per 100,000 men. India, China, and Colombia had the lowest incidence (0.5, 1.3, and 2.2, respectively) per 100,000 men. The annual percent changes for overall testicular cancer incidence significantly increased in the European countries Sweden 2.4%, (2.2; 2.6); UK 2.9%, (2.2; 3.6); and Spain 5.0%, (1.7; 8.4), Australia 3.0%, (2.2; 3.7), and China 3.5%, (1.9; 5.1). India had the lowest overall testicular cancer incidence −1.7%, (−2.5; −0.8). Annual percent changes for overall testicular cancer mortality rates were decreasing in all study populations, with the greatest decline observed in Sweden −4.2%, (−4.8; −3.6) and China −4.9%, (−6.5; −3.3). Conclusion Testicular cancer is increasing in incidence in many countries; however, mortality rates remain low and most men are cured. An understanding of the risks and long-term side effects of treatment are important in managing men with this disease. PMID:24204171

    Objective: To discuss the clinical therapeutic effect and side reaction of superselective uterine arterial chemoembolization therapy for the treatment of cervical cancer. Methods: Bilateral uterine arterial chemoembolization was performed in 33 patients with pathologically-proved cervical cancer. The infusion drugs included DDP or L-OHP, EADM, MMC and 5-Fu. The Gelfoam particle was employed as embolic agent. The therapeutic effect evaluated by observing the improvement of clinical symptoms and the volume reduction of the tumor. Results: Of the total 33 patients with pathologically-confirmed cervical cancer, squamous cell carcinoma was seen in 29 and adenocarcinoma in 4. Based on FIGO classification (established by Federation International of Gynecology and Obstetrics), 6, 23 and 4 patients were classified in stage Ⅰ, Ⅱ and Ⅲ respectively. The angiography conducted during the procedure showed that the uterine arteries were markedly dilated, and spiral tumor-feeding arteries as well as tumor stain were also observed. Technical success together with perfect chemoembolization was achieved for 57 uterine arteries in 33 patients. Among the 33 patients, the interventional treatment was carried out three times in 2, two times in 2 and single time in 29. One week after the initial interventional procedure the remission rate of the clinical symptoms was 96% for squamous cell carcinoma and 100% for adenocarcinoma. One month after the treatment, the mean tumor volume was decreased by 30%, the tumor volume reduction for squamous cell carcinoma was 27.6% and was 50.0% for adenocarcinoma. Surgical resection after interventional therapy was carried out in 21 cases and additional radiotherapy after surgery or interventional procedure was adopted in 11 cases. The main adverse reactions after interventional procedure included fever, leucocytopenia, nausea, vomiting, abdominal pain, etc. Conclusion: Superselective uterine arterial chemoembolization is one of effective

    Uterine cervical cancer is still the second largest cancer in women worldwide, despite of effective screening methods. Radiotherapy is used to treat all the stages of cervical cancer and more than 60% of cervical cancer patients receive radiotherapy. New therapeutic targets or approaches are needed to further increase the results of radiotherapy. In the present study, we demonstrated the radiation induced overexpression and nuclear export of FTS in cervical cancer cells. Furthermore, we showed that silencing of FTS expression with FTS shRNA enhanced radiosensitivity of cervical cancer cells, induced cell cycle arrest and apoptosis FTS is involved in radioresistance of cervical cancer. Targeted inhibition of FTS can shutdown the key elemental characteristics of cervical cancer and could lead to an effective therapeutic strategy.

    The concordance rates between preoperative diagnostic imagings and postoperative pathologic findings were examined in a total of 36 patients with resectable uterine cancer (19 with cervical cancer and 27 with endometrial cancer). The accuracy of CT was 47 % in the evaluation of cervical cancer involvement to the parametrium; and was 83 % in the evaluation of wall involvement of endometrial cancer. The concordance rate was 74 % in the evaluation of stage-grouping in endometrial cancer. Out of 8 patients with resectable stage II cervical cancer, four (50 %) were found to have had involvement to the parametrium by transrectal echography. The results indicate that CT scanning and transrectal echography have limitations in the diagnosis of cervical cancer involvement to the parametrium. (Namekawa, K.)

    In France, Corsica appears to be one of the most exposed regions to the fallout from the Chernobyl accident. Taking into account the scientific knowledge at that time, it was decided to focus studies on thyroid cancers. A study was carried out in order to estimate thyroid cancer incidence in Corsica for the periods 1998-2001 and 2002-2006. The study identified incident thyroid cancer cases between 1998 and 2006 among residents in Corsica. Data were collected using information from the hospitals (PMSI) and the local health insurance funds (ALD). Cases were validated through medical records before inclusion in the study. Over the period of study, 342 cases of thyroid cancer, rather women and relatively young patients, were identified in Corsica. Incidence rate of the thyroid cancer was high, but stable among men, and with a slight increase among women, particularly between 2002 and 2006. However, incidence rate and clinical characteristics of thyroid cancer in Corsica are not exceptional and are similar to those in other French districts. (authors)

  1. Germline mutation in RNASEL predicts increased risk of head and neck, uterine cervix and breast cancer.

    Full Text Available UNLABELLED: THE BACKGROUND: Ribonuclease L (RNASEL, encoding the 2'-5'-oligoadenylate (2-5A-dependent RNase L, is a key enzyme in the interferon induced antiviral and anti-proliferate pathway. Mutations in RNASEL segregate with the disease in prostate cancer families and specific genotypes are associated with an increased risk of prostate cancer. Infection by human papillomavirus (HPV is the major risk factor for uterine cervix cancer and for a subset of head and neck squamous cell carcinomas (HNSCC. HPV, Epstein Barr virus (EBV and sequences from mouse mammary tumor virus (MMTV have been detected in breast tumors, and the presence of integrated SV40 T/t antigen in breast carcinomas correlates with an aggressive phenotype and poor prognosis. A genetic predisposition could explain why some viral infections persist and induce cancer, while others disappear spontaneously. This points at RNASEL as a strong susceptibility gene. METHODOLOGY/PRINCIPAL FINDINGS: To evaluate the implication of an abnormal activity of RNase L in the onset and development of viral induced cancers, the study was initiated by searching for germline mutations in patients diagnosed with uterine cervix cancer. The rationale behind is that close to 100% of the cervix cancer patients have a persistent HPV infection, and if a defective RNase L were responsible for the lack of ability to clear the HPV infection, we would expect to find a wide spectrum of mutations in these patients, leading to a decreased RNase L activity. The HPV genotype was established in tumor DNA from 42 patients diagnosed with carcinoma of the uterine cervix and somatic tissue from these patients was analyzed for mutations by direct sequencing of all coding and regulatory regions of RNASEL. Fifteen mutations, including still uncharacterized, were identified. The genotype frequencies of selected single nucleotide polymorphisms (SNPs established in the cervix cancer patients were compared between 382 patients

    Cancer is one of the major health problems worldwide. In this article, we present for the first time the cancer incidence trends, the distribution and the socioeconomic profile of incident cancer cases in Eastern Morocco over a period of eight years. Retrospective descriptive study of patients diagnosed with cancer at the Hassan II Regional Oncology Center (ROC) since it was created in October 2005 until December 2012. During the study period, the ROC was the only hospital specialized in cancer care in Eastern Morocco. A total of 7872 incident cases of cancer were registered in Eastern Morocco. Among these incident cases 5220 cases were women and 2652 were men, with a female to male ratio of 1.97. The mean age at diagnosis was 58 years for males and 52 for females and 94% of the patients aged over 30 years. For both sexes combined and for all cancer sites, breast cancer was the commonest followed by cervix uteri, colon-rectum, lung, nasopharynx, and stomach cancers. The most common cancer in women was breast cancer, followed respectively by cervix uteri cancer, colon-rectum cancer, ovary cancer, and stomach cancer. In men, the lung cancer ranked first, followed respectively by colon-rectum cancer, nasopharynx cancer, prostate cancer, and stomach cancer. For most cancers, crude incidence rates (CR) have increased significantly. The CR for all cancers combined has increased from 56.6 to 80.3 per 100,000 females and from 32.3 to 42.6 per 100,000 males during the study period. Patients profile analysis showed that 79% of cancer patients were from urban areas, 83% were unemployed and 85% had no health insurance. The distribution of cancers in Eastern Morocco is different from those observed in other regions of Morocco. Unlike most countries, women were much more affected with cancer than men in Eastern Morocco. More importantly, the rates of many cancers are rising. Therefore, our data justify the need to develop effective programs for cancer control and prevention in

    In November of 1982 the Colorado Department of Health completed an epidemiologic investigation of leukemia, multiple myeloma, and cancers of the lung, stomach, pancreas and colon in Mesa County, Colorado for the years 1970 to 1979. This investigation was performed in response to a concern that the presence of uranium mill tailings in some Mesa County homes presents a potential cancer hazard. The results of the investigation show that the incidence of multiple myeloma, colon, stomach and pancreatic cancer are not above expected rates. The incidence of leukemia is not above expected rates for the entire study period, 1970 to 1979. The incidence of lung cancer appears elevated when compared to the The Third National Cancer Survey data for Colorado but lower than expected when compared to Surveillance, Epidemiology and End Results data. To further examine the leukemia and lung cancer incidence findings, a case/control study was conducted. The controls consisted of colon, stomach and pancreatic cancer cases. The results of the leukemia case/control analysis show no association with the radiation exposure variables: occupational radiation exposure; uranium mining exposure; having ever lived in a type A home (uranium tailings home); and radiation therapy. The lung cancer case/control analysis shows a significant association with only the radiation exposure variable, uranium mining history, indicating cases were more likely to have been uranium miners than were controls. As with leukemia, the study found no association between lung cancer and living in a uranium mill tailings home. The relatively low radiation exposures typical of type A homes and the small number of persons exposed make it very difficult to establish, by epidemiologic methods, that a risk exists

    This report compares cancer incidence and mortality among atomic bomb survivors in the Radiation Effects Research Foundation Life Span Study (LSS) cohort. Because the incidence data are derived from the Hiroshima and Nagasaki tumor registries, case ascertainment is limited to the time (1958-1987) and geographic restrictions (Hiroshima and Nagasaki) of the registries, whereas mortality data are available from 1950-1987 anywhere in Japan. With these conditions, there were 9,014 first primary incident cancer cases identified among LSS cohort members compared with 7,308 deaths for which cancer was listed as the underlying cause of death on death certificates. When deaths were limited to those occurring between 1958-1987 in Hiroshima or Nagasaki, there were 3,155 more incident cancer cases overall, and 1,262 more cancers of the digestive system. For cancers of the oral cavity and pharynx, skin, breast, female and male genital organs, urinary system and thyroid, the incidence series was at least twice as large as the comparable mortality series. Although the incidence and mortality data are dissimilar in many ways, the overall conclusions regarding which solid cancers provide evidence of a significant dose response generally confirm the mortality findings. When either incidence or mortality data are evaluated, significant excess risks are observed for all solid cancers, stomach, colon, liver (when it is defined as primary liver cancer or liver cancer not otherwise specified on the death certificate), lung, breast, ovary and urinary bladder. No significant radiation effect is seen for cancers of the pharynx, rectum, gallbladder, pancreas, nose, larynx, uterus, prostate or kidney in either series. There is evidence of a significant excess of nonmelanoma skin cancer in the incidence data, but not in the mortality series. 19 refs., 2 figs., 10 tabs

    Brain metastases from cervical cancer are extremely rare. We report on two patients who developed cerebellar metastases following uterine cervical cancer. The interval between diagnosis of the primary cancer and diagnosis of brain metastasis was 8 months. The main complaint was symptoms of increased intracranial pressure and cerebellar syndrome. Surgical excision of the brain lesion followed by radiation therapy was performed in the first case. The second patient received palliative radiation therapy. The first patient died 8 months after diagnosis. The second patient is alive 2 months after diagnosis. (authors)

    The efficacity of irradiation therapy, as a unique method, was evaluated in 50 women with diagnosed uterine corpus cancer in 1/1 stage of clinical development. These patients refused other forms of therapy (surgery). The results were compared with those observed in 232 women treated by complex technique (surgery and irradiation). The percent of 5 years survival rate in the subjects treated by irradiation only made 54%, while in the complex therapy group it made 81.1%. The difference was found significant. The complications resulting from the irradiation therapy were present in 13 women (26%), while in the complex therapy group these were met in 25 women (10.8%) which difference was also significant. These facts strongly advocate the superiority of complex treatment in recent cases of uterine corpus cancer. (author)

    Objective: To evaluate the therapeutic effect of intra-arterial chemotherapy with Ddp and 5-Fu via bilateral uterine arteries for advanced uterine cervical cancer. Methods: During the period of Jan. 2006-Jan. 2009, initial intra-arterial chemotherapy by using a combination of Ddp and 5-Fu via bilateral uterine arteries was performed in 72 patients (mean age 42.9 years) with advanced uterine cervical caner. Of 72 patients, stage I b2 cervical cancer was confirmed in 28, stage II a in 12 and stage II b in 32. Pathologically, cervical squamous cell carcinoma was seen in 56 and cervical adenocarcinoma in 16 patients. Ultrasonography and physical examination were conducted both before and after intra-arterial chemotherapy. The therapeutic results,complications,the surgical resection rate and the pathologic findings were observed and statistically analyzed. Results: Fifty-four patients received one treatment course and 18 patients received two treatment courses. The over all response rate was 77.8%. The response rates of patients with I b2, II a and II b cervical cancer were 92.9%, 83.3% and 62.5% respectively, the difference between three groups was statistically significant (P < 0.05). And the response rates of patients with squamous cell carcinoma and adenocarcinoma were 85.7% and 50.0% respectively, the difference between the two was statistically significant (P < 0.05). The most common side-effects included gastrointestinal symptoms and bone marrow suppression. Thirty-four patients received radical hysterectomy,among them, 22 (78.6%) had stage I b2, 8 (66.7%) had stage II a and 4 (12.5%) had stage II b cervical cancer (P < 0.05). Pathologic exam found no vaginal invasion and ovarian metastasis in all 34 patients. The occurrence of metastasis to lymph nodes and para uterine infiltration were 17.6% and 11.8% respectively. Conclusion: Intra-arterial chemotherapy with a combination of DDP and 5-Fu via bilateral uterine arteries can safely and effectively reduce the

    Objective: The present study was aimed at developing a thermoluminescent dosimetric system capable of assessing the doses delivered to the rectum of patients submitted to high-dose-rate brachytherapy for uterine cervix cancer. Materials and methods: LiF:Mg,Ti,Na powder was the thermoluminescent material utilized for evaluating the rectal dose. The powder was divided into small portions (34 mg) which were accommodated in a capillary tube. This tube was placed into a rectal probe that was introduced into the patient's rectum. Results: The doses delivered to the rectum of six patients submitted to high-dose-rate brachytherapy for uterine cervix cancer evaluated by means of thermoluminescent dosimeters presented a good agreement with the planned values based on two orthogonal (anteroposterior and lateral) radiographic images of the patients. Conclusion: The thermoluminescent dosimetric system developed in the present study is simple and easy to be utilized as compared to other rectal dosimetry methods. The system has shown to be effective in the evaluation of rectal doses in patients submitted to high-dose-rate brachytherapy for uterine cervix cancer. (author)

    As part of the National Plutonium Workers Study, cancer incidence for 1969 to 1978 among employees of the Los Alamos National Laboratory was investigated. Incident cancers were identified by a computer match of the Los Alamos employed roster against New Mexico Tumor Registry files. The resulting numbers of total and site-specific cancers were compared to the numbers expected based on incidence rates for the State of New Mexico, specific for age, sex, ethnicity, and calendar period. For Anglo males, significantly fewer cancers than expected (SIR = 0.60, 95% CI 0.44 to 0.79) were found. This resulted from marked deficits of smoking-related cancers, particularly lung (2 observed, 19.4 expected) and oral (1 observed, 6.5 expected) cancer. Similarly, no smoking-related cancers were detected among Anglo females, though they had a slight nonsignificant excess of breast cancer (14 observed, 9.1 expected) and a suggestive excess of cancer of the uterine corpus (2 observed, 0.25 expected). The pattern of cancerincidence among Anglo employees is typical of high social class populations and not likely related to the Los Alamos working environment

    Purpose: Point A, used for dose specification for intracavitary brachytherapy for cervical cancer, is the point at which the uterine artery and ureter cross. This study assessed compatibility of commonly used traditional point A (TPA) and actual anatomic point A (APA). Methods and Materials: We visualized and placed radiopaque clips at the APA during pelvic and paraaortic lymphadenectomy in 11 patients with cervical carcinoma. Orthogonal and oblique radiographs were obtained after insertion of brachytherapy applicators. We measured the distance between the TPA and APA and estimated the brachytherapy dose to each of the two points. Results: A total of 64 brachytherapy treatments were performed. The mean distances between the TPA and APA were 5.2 ± 1.0 cm on the right and 5.4 ± 1.1 cm on the left. The estimated brachytherapy doses delivered to the APA as a percentage of the presumed 500-cGy fraction size to the TPA were 35.2% (176.6 ± 59.0 cGy) on the right and 30.0% (150.2 ± 42.9 cGy) on the left. The marked discrepancy in the position of the two points was not related to individual kinetic variations during brachytherapy treatment, tumor size, or bladder filling. Conclusions: The conventional TPA does not provide an accurate estimate of the APA determined during lymphadenectomy, indicating a need to reevaluate the current practice for determining the brachytherapy prescription for cervical cancer.

    It has been suggested that the cancer risk of migrants from low-income to high-income countries will converge toward the levels of their host country. However, comparisons with country of origin are mostly lacking. We compared cancer incidence and mortality rates of Surinamese migrants in the Netherlands to both native Dutch and Surinamese levels. Data covering the period 1995-2008 were obtained from Surinamese and Dutch national cancer registries and national cause-of-death registries. Cancer incidence was studied for 21 types of cancer and cancer mortality for nine types. We calculated age-standardized incidence/mortality ratios (SIR/SMR) for the Surinamese migrants and for Suriname, using the native Dutch population as reference. Significantly lower overall cancer incidence (SIR = 0.77, 95% CI = 0.69-0.84) and mortality rates (SMR = 0.63, 95% CI = 0.55-0.72) were found for Surinamese migrants compared to native Dutch. Generally, cancer risk was lower for most cancers (e.g., cancer of the breast, colon and rectum, lung), but higher for other cancers (e.g., cancer of the uterine cervix, liver). For most cancers, cancer risk of the Surinamese migrants was in-between Surinamese and native Dutch levels. Importantly, for many cancers, migrants' incidence and mortality rates had not closely approached native Dutch rates. For skin cancer, incidence levels for Surinamese migrants were lower than both Surinamese and native Dutch levels. The results suggest that cancer incidence and mortality rates of Surinamese migrants generally converge from Surinamese toward Dutch levels, though not for all cancer types. Overall, Surinamese migrants still had a much more favorable cancer profile than the native Dutch population.

  13. Unmodifiable variables related to thyroid cancer incidence

    Full Text Available The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative risk for each sex to develop thyroid carcinoma. The incidence of thyroid carcinoma was higher for women than for men, with a higher relative risk in the female subgroup. Incidence was also highest in the 50-60-year-old group. Given that studies show better survival for women and for younger patients, even when presenting with advanced disease, compared with older, male patients, such prognostic indicators should be a factor in the treatment decision.

    Full Text Available We report here on a case of 51-year-old woman with metastatic small cell carcinoma of the breast that came from her cancer of the uterine cervix. She underwent radical hysterectomy with bilateral salpingo-oophorectomy due to small cell carcinoma of the uterine cervix, and adjuvant radiotherapy was administered to the pelvis. Breast metastasis with a palpable mass then occurred 3 months after the primary surgery. Simple mastectomy and adjuvant chemotherapy were performed. She initially showed a good response to the therapy, yet she ultimately died of multiple metastases with a fulminating disease course. This is an extremely rare case, and only 1 similar case has been reported earlier, so we report on this case along with a review of the relevant literature.

    African American men have among the highest prostate cancer incidence rates in the world yet rates among their African counterparts are unclear. In this paper, we compared reported rates among black men of Sub-Saharan African descent using data from the International Agency for Research on Cancer (IARC) and the National Cancer Institute Surveillance, Epidemiology, and End Results Program for 1973-2007. Although population-based data in Africa are quite limited, the available data from IARC showed that rates among blacks were highest in the East (10.7-38.1 per 100,000 man-years, age-adjusted world standard) and lowest in the West (4.7-19.8). These rates were considerably lower than those of 80.0-195.3 observed among African Americans. Rates in Africa increased over time (1987-2002) and have been comparable to those for distant stage in African Americans. These patterns are likely due to differences between African and African American men in medical care access, screening, registry quality, genetic diversity, and Westernization. Incidence rates in Africa will likely continue to rise with improving economies and increasing Westernization, warranting the need for more high-quality population-based registration to monitor cancer incidence in Africa.

    One hundred fifty-four patients with the carcinoma of the uterine cervix were studied retrospectively to assess the result and impact of treatment at Department of Radiation Oncology, Korea University, Hae-Wha Hospital from Feb 1981 through Dec. 1986. Prior to radiotherapy, the patients were evaluated and staged by recommendation of FIGO including physical examination, pelvic examination, cystoscopy, rectosigmoidoscopy, chest X-ray, IVP, Ba enema. Also, an additional pelvic CT scan was obtained for some of the patients. The patients were treated by radiotherapy alone or adjuvant postoperative irradiation; In case of radiation therapy only, whole pelvic irradiation was given with C0-69 teletherapy unit via AP and PA parallel opposing fields or 4-oblique fields, 180 cGy per day, 5 days per week and intracavitary insertion was performed. Three dimensional quantitative demonstration of tumor volume is also important in planning radiation therapy. Another advantage of CT scan was detection of recurrent tumor after radiation or surgery. Local control rate of tumor according to the size was 91.3% for less than 5 cm in size and 44.6% in tumor over 5 cm (p<0.0068). Thirty out of 50 recurrent sites has locoregional failures and 17 cases has distant metastases. And the papa-aortic lymph nodes were the most common site for distant metastases. The most common complication was temporal rectal bleeding which was controlled most by conservative management. However, 4 patients required for endoscopic cauterization. The 5-year survival rates showed; stage la and lb 95%, stage lla 81% stage llb 67%, stage llla 37.7%, stage lllb 23%, and 3-year survival rate of stage lVa showed 11.6%, retrospectively

    1993-01-01

    Magnetic resonance imaging (MRI) was performed in 62 patients with uterine cervical cancer and the preoperative MRI findings were compared with the pathological findings following surgery. The surgical stages of 62 patients were 2 at stage 0, 18 at stage Ia, 19 at stage Ib, 9 at stage IIa, 11 at stage IIb, 2 at stage IIIa, and 1 at stage IIIb. The MRI findings in the present study included: (1) the existence of a high intensity area (HIA) in the uterine cervix or minimum thickness of residual normal cervical tissue, (2) necrotic cavity, (3) pyometra, (4) irregular margin of the cervix, (5) parametrial invasion, (6) vaginal invasion, (7) bladder invasion, and (8) lymph node enlargement. No HIA was observed in any patient with stage 0 or stage Ia, in 8 patients with stage Ib, and in 2 patients with stage IIa, while all patients with cancer tissues greater than 10 mm in diameter had a HIA. In 39 patients in whom hysterectomy was undergone without conization, the findings of MRI correlated significantly (r=0.929, p<0.001) with the minimum thickness of residual normal cervical tissue by the pathological measurement. When the irregular margin of the cervix was regarded as a disruption of the cervical myo-metrium by cancer tissue, accuracy was 87%. Furthermore, the degrees of accuracy for parametrial invasion, vaginal invasion and bladder invasion were 92%, 90% and 94%, respectively. When lymphnodes greater than 15 mm in diameter were regarded as a positive in MRI, accuracy was 88%. The present results indicate that MRI is clinically effective in preoperatively evaluating the extension of uterine cervical cancer. (author)

    Background: Oral carcinomas (OCs) make up a significant proportion of head and neck carcinomas (HNCs) and are an important cause of morbidity and mortality globally. The purpose of this population-based study was to determine trends in incidence and survival in OC in the Danish population from 1980...... to 2014. Material and methods: This study covered all patients registered in the nationwide Danish cancer registry (DCR) in the period 1980–2014. Age-adjusted incidence rate (AAIR) per 100,000 and annual percentage change (APC) were evaluated. Also, 5-year overall survival (OS) was calculated with Cox......-standardized incidence of OC during the last 30 years in Denmark, and also an improvement in survival. The 5-year OS was significantly better in recent years even when we adjusted the analysis for relevant covariates....

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid 99m Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

    To evaluate the usefulness of magnetic resonance imaging (MRI) in diagnosing residual or recurrent tumors of cervical cancer after radiation therapy, we investigated the time difference between MRI and gynecologic findings in the diagnosis of residual or recurrent tumor in 12 patients with invasive cervical cancer. We defined a positive finding for residual or recurrent tumor as an uterine cervical mass isointense to muscle on T1-weighted images and hyperintense on T2-weighted images, and when a positive biopsy specimen was obtained. Two patients were diagnosed as having a residual or recurrent tumor by MRI. Positivity was demonstrated four and seven months later, respectively. MRI was more useful in the earlier diagnosis of residual or recurrent tumor of cervical cancer after radiation therapy than uterine biopsy. There was one patient whose differentiation from residual tumor or radiation-induced necrosis or inflammation on MRI was difficult. MRI and gynecologic check-up at a regular interval after radiation therapy was needed to distinguish them. One patient was diagnosed as having a recurrent tumor by gynecologic finding three months earlier than by MRI. Follow-up MRI examinations at a regular interval in addition to gynecologic examination is necessary for the early detection of recurrent cervical cancer after radiation therapy. (author)

    In 58 women with diagnosed stage 1 uterine cervix cancer radium (27 women) or cesium (31 women) were applied into the vagina or in the uterine cavity, then after about 7 weeks they were submitted to surgical treatment - radical hysterectomy with adnexectomy and excision of the obturatory and iliac lymphnodes (Wertheim Meigs operation). In 16 of these women, considering the marked dimensions of the neoplasm teletherapy in a decreased dose preceded the brachytherapy. Total destruction of the neoplasmatic outgrowth as a result of preoperative radiotherapy was met in 44 women (76%). In 8 women the excised tissues revealed neoplasmatic cells persisting in the uterine cervix and in 6 - in the lymphnodes. These women underwent subsequent post-operative teletherapy. The complications of the adapted technique were analysed and found to fall close within limits of those, accepted in cases of classic primary surgical treatment. No exits and no fistulas were met in the material. The value of brachytherapy applied before surgery is evident as it permitted to evade the post-operative teletherapy in 55% of women and to reduce the external irradiation dose in further 21% of women.

    Full Text Available INTRODUCTION: There is a need to assess risk of second primary cancers in prostate cancer (PCa patients, especially since PCa treatment may be associated with increased risk of second primary tumours. METHODS: We calculated standardized incidence ratios (SIRs for second primary tumours comparing men diagnosed with PCa between 1980 and 2010 in the Canton of Zurich, Switzerland (n = 20,559, and the general male population in the Canton. RESULTS: A total of 1,718 men developed a second primary tumour after PCa diagnosis, with lung and colon cancer being the most common (15 and 13% respectively. The SIR for overall second primary cancer was 1.11 (95%CI: 1.06-1.17. Site-specific SIRs varied from 1.19 (1.05-1.34 to 2.89 (2.62-4.77 for lung and thyroid cancer, respectively. When stratified by treatment, the highest SIR was observed for thyroid cancer (3.57 (1.30-7.76 when undergoing surgery, whereas liver cancer was common when treated with radiotherapy (3.21 (1.54-5.90 and kidney bladder was most prevalent for those on hormonal treatment (3.15 (1.93-4.87. Stratification by time since PCa diagnosis showed a lower risk of cancer for men with PCa compared to the general population for the first four years, but then a steep increase in risk was observed. CONCLUSION: In the Canton of Zurich, there was an increased risk of second primary cancers among men with PCa compared to the general population. Increased diagnostic activity after PCa diagnosis may partly explain increased risks within the first years of diagnosis, but time-stratified analyses indicated that increased risks remained and even increased over time.

    Full Text Available Rationale: Analysis of the cancer incidence and mortality in the population is of major importance for planning of measures aimed at improvement of organization of medical care to cancer patients, ensuring high quality and availability of this type of medical care.Aim: To evaluate cancer-related incidence and mortality rates and structure among the population of the Moscow Region depending on patient gender and tumor localization.Materials and methods: The estimation and analysis of incidence and mortality rates was performed based on the Reporting Form of the Federal Statistic Surveillance #7 “Information on disorders related to malignant tumors” in the Moscow Region in 2014. For mortality analysis, including that among pediatric patients, we used data from the State Statistics Service of the Moscow Region.Results: In 2014, there were 25 600 new cases of malignancies diagnosed in the Moscow Region, that corresponded to the incidence rate of 363.2 per 100,000 of the population. The leading types of newly diagnosed tumors in men were prostate cancer, as well as tracheal, bronchial and lung cancers (54.2 and 47.0 per 100,000 of male population, respectively. In women, the highest incidence rates were found for breast and skin cancers (86.0 and 58.9 per 100,000 of female population, respectively. According to the data from Rosstat, in 2014, the overall cancer mortality rate in the Moscow Region was 228.1 per 100,000 of the population. Among the causes of cancer mortality in men, the leading one was tracheal, bronchial and lung cancer (22.2%, followed by stomach cancer (13.3% and prostate cancer (8.1%. In women, the leading cause of cancer mortality was breast cancer (16.6%, followed by ovarian, uterine and cervical cancers (14.1% and stomach cancer (11.4%.Conclusion: Based on the results of medical and statistical analysis of cancer incidence and mortality rates, the main direction of improvement of medical care to cancer patients and the ways

    To investigate the role of radiotherapy (RT) in and to suggest radiotherapeutic strategies for patients presenting with disseminated cervical cancer. We retrospectively analyzed 50 patients diagnosed as the disseminated cervical cancer with distant lymph nodal or visceral organ metastasis between September 1980 and August 2012. Patients were divided into two subgroups according to visceral organ metastasis: 35 patients diagnosed with distant lymph node metastasis only (group A) and 15 patients with visceral organ metastasis (group B). All patients received external beam RT to the pelvis (median dose 45 Gy) and high-dose rate intracavitary RT (median dose 30 Gy). Thirty-nine patients (78%) received chemotherapy. Median follow-up time was 74 months. The 5-year pelvic control rate (PCR) was 85.8%, and the progression-free survival (PFS), and overall survival (OS) rates were 28.7%, and 36.2%, respectively. The major treatment failure was systemic progression (32 patients, 64%). The 5-year PCRs in groups A and B were 87.4% and 74.7%, respectively (p > 0.05). Meanwhile, PFS and OS rates for group A were significantly better than those for group B (35.3% vs. 13.3%, p = 0.010; and 46.3% vs. 13.3%, p = 0.009, respectively). Our data revealed considerable prognostic heterogeneity in disseminated cervical cancer. Even though a high PCR was achieved in patients treated with definitive RT, survival outcomes were dependent on progression of visceral organ metastasis. Therefore, personalized RT and chemotherapy treatment strategies according to the presence of visceral organ metastasis in disseminated cervical cancer patients may help improve clinical outcomes

    Full Text Available Background: Geographic differences in the incidence of cancers may suggest unique genetic or environmental exposures that impact the risk of acquiring cancer. This research aims to determine the incidence rate and geographical distribution of common cancers among Iranian children. Methods: In this ecological study, we extracted data that pertained to the incidence rate of common cancers among children from reports by the National Registry of Cancer and Disease Control and Prevention in 2008. A map of the cancer incidence rates was designed by using geographic information system. Results:The most common cancer sites among children were the hematology system, brain and central nervous system, and lymph nodes. The central provinces had the lowest cancer incidences. Conclusion: The considerable variation in incidence of childhood cancers in Iran suggests a possible potential environmental risk factor or genetic background related to this increased risk among children.

    Case 1: The 61-year-old woman developed uterine cancer at age 50. Radiation therapy was initiated to the pelvic lumen from both anterior and posterior sides with a total dose of 21,000 rads. Radiation ulcerative enterocolitis and dermatitis revealed at the end of the therapy. At age 52 (2 years after radiation), she noticed muscle weakness and dysesthesia of the lower legs. These symptoms progressed and amyotrophy of the legs appeared. At age 54 (4 years after radiation), she became unable to walk. Case 2: The 51-year-old woman developed uterine cancer at age 40. Postoperative radiation was initiated by the same dose and the same way as in Case 1 and she suffered from radiation dermatitis. At age 49 (9 years after radiation), she noticed dysesthesia of the right toe, which gradually spread to another side. Ten years after radiation, she began to note weakness in dorsiflexion of feet. Case 3: The 69-year-old woman developed uterine cancer at age 67. Radiation (Linac 4,000 rads, Ralstron 2,000 rads) was performed for 3 months into the pelvic lumen. Two years later, she noted dysesthesia and weakness of her legs. These symptoms progressed gradually. In these 3 cases, EMG showed neurogenic changes, suggesting peripheral nerve lesions. Nerve conduction velocities were decreased. Nerve and muscle biopsies revealed neurogenic changes. No abnormal findings were detected by spinal X-rays and myelography. The neurological findings of these patients were compatible with the lumbo-sacrol plexus injuries apparently due to late radiation effect. (J.P.N.).

    The present study was undertaken to evaluate the stage classification (FIGO) by using CT in 50 cases with cancer of the uterine cervix in which the final stage had been diagnosed. An accurate diagnosis was obtained in 6 of 14 Ib cases, 14 of 21 IIa cases, 5 of 6 IIb cases, 2 of 3 IIIa cases, 3 of 3 IIIb cases and 3 of 3 IVa cases, for a total of 33 of 50 (66 %). The diagnostic rate for Ib and IIa staging was 57 %, while that for IIb or more was 87 %, but the accuracy rate in IIIb and IVa was 100 %. As the equipment, a high resolutional GE 9800 CT using a special technique was employed. Employing special pretreatment for the patient, it became possible to accurately grasp the pelvic condition of the patients. CT evaluation was related to the extent of the cervical cancer and the presence of infiltration into the vaginal wall. According to a 4-stage classification of the CT image, the extent of infiltration to surrounding parametrium and the bladder was determined. As a result, the sensitivity for evaluating invasion into surrounding tissue raised 92 %, and it showed 100 % for cases with adhesion or invasion of the bladder. Therefore, CT can an extremely effective method to determine the clinical staging of cancer of the uterine cervix.

    Today in day the narrow relationship is known among the viral infection by VHP and the cancer of uterine neck; in this pathology they also appear the proteins E6 and E7 that are target of oncogenes and important part in the course of cancer of uterine neck. It intends as hypothesis that when to a patient with neck cancer, it is administered radiotherapy, there is lysis tumoral that liberates viral components that then E7 acts on the proteins being given an immunologic answer of cellular type, activating clones. When the immunologic answer is positive, the results to the treatment are but favorable and vice versa. The objective was to determine if the virus is detected after the treatment with the radiotherapy and if the titles of antibodies had increased or diminished. An analysis of the age was made, of the size of the tumor, of the state and one of the virus of the papilloma was looked for before and after the treatment, quantifying the variation (increase or decrease) of its quantity, finally it was observed if the presage after the treatment was related with the patient's survival

    The conventional local treatment methods (surgery and radiation) for cervical cancer have reached a plateau in terms of survival benefit and, therefore, in this review, new treatment strategies (combined chemotherapy [CT] and local therapy) to overcome the poor prognosis were examined in high-risk groups. The effectiveness of neoadjuvant chemotherapy (NAC) administered prior to radiotherapy (RT) has not been confirmed for any disease stages. But NAC followed by surgery may improve survival in patients with stage Ib2 compared with surgery alone; and in patients with stage Ib2 to IIB compared with RT alone. Five large randomized clinical trials (RCTs) demonstrated a significant survival benefit for patients treated with concurrent chemoradiotherapy (CCRT), using a cisplatin (CDDP)-based regimen, with a 28%-50% relative reduction in the risk of death. In addition, the results of a meta-analysis of 19 RCTs of CCRT (1981-2000) involving 4580 patients showed that CCRT significantly improved overall survival (OS) hazard ratio ([HR] 0.71; P<0.0001), as well as progression-free survival (PFS; HR 0.61; P<0.0001). In line with these results, CCRT is currently recommended as standard therapy for advanced cancer (stage III/IVA) in the United States. However, there remains much controversy and uncertainty regarding the optimal therapeutic approaches, especially for patients with advanced cancer. Additional RCTs should be conducted to find the optimal CT regimen and RT for Japanese patients, considering acute and late complications, as well as differences in pelvic anatomy, total radiation dose, and RT procedures between Japan and other countries. Evidence obtained from such studies should establish the optimal CCRT treatment protocol and define the patient population (disease stage) that the protocol really benefits. (author)

    Gynecologic cancer is a heterogeneous group of diseases both functionally and morphologically. Today, PET coupled with computed tomography (PET/CT) or PET/MR imaging play a central role in the precision medicine algorithm of patients with gynecologic malignancy. In particular, PET/CT and PET/MR imaging are molecular imaging techniques that not only are useful tools for initial staging and restaging but provide anatomofunctional insight and can serve as predictive and prognostic biomarkers of response in patients with gynecologic malignancy.

    Full Text Available Abstract Background Endometrial cancer studies have led to a number of well-defined but mechanistically unconnected genetic and environmental risk factors. One of the emerging modulators between environmental triggers and genetic expression is the microbiome. We set out to inquire about the composition of the uterine microbiome and its putative role in endometrial cancer. Methods We undertook a study of the microbiome in samples taken from different locations along the female reproductive tract in patients with endometrial cancer (n = 17, patients with endometrial hyperplasia (endometrial cancer precursor, n = 4, and patients afflicted with benign uterine conditions (n = 10. Vaginal, cervical, Fallopian, ovarian, peritoneal, and urine samples were collected aseptically both in the operating room and the pathology laboratory. DNA extraction was followed by amplification and high-throughput next generation sequencing (MiSeq of the 16S rDNA V3-V5 region to identify the microbiota present. Microbiota data were summarized using both α-diversity to reflect species richness and evenness within bacterial populations and β-diversity to reflect the shared diversity between bacterial populations. Statistical significance was determined through the use of multiple testing, including the generalized mixed-effects model. Results The microbiome sequencing (16S rDNA V3-V5 region revealed that the microbiomes of all organs (vagina, cervix, Fallopian tubes, and ovaries are significantly correlated (p 4.5. Conclusions Our results suggest that the detection of A. vaginae and the identified Porphyromonas sp. in the gynecologic tract combined with a high vaginal pH is statistically associated with the presence of endometrial cancer. Given the documented association of the identified microorganisms with other pathologies, these findings raise the possibility of a microbiome role in the manifestation, etiology, or progression of endometrial cancer that

    We examined 19 patients with post-irradiation intestinal injury in the uterine cervix cancer for 12 years between 1985 and 1996. We discuss the usefulness and complications of surgery, mainly colostomy. The patients aged from 36 to 80 (average age 61) were treated, and their disease states were 12 cases of rectovaginal fistula, 2 of small intestinal fisfula, 1 of rectum posterior membranous fistula, 3 of proctostenosis, and 14 of proctitis with hemorrhage (including duplication). Surgical methods used were 18 cases of colostomy (2 cases were treated under peritoneum mirror) and 2 of enterocolostomy (including duplication). Eleven out of 19 patients who underwent surgery are alive now. Generally the post-irradiation intestinal injury was intractable, and the method of treatments were limited due to the coexistence of various diseases. The colostomy is safe and less invasive. Therefore patients with uterine cervix cancer having various complications can obtain high quality of life (QOL) such as the improvement of anemia and/or the increase of digestion by the colostomy.

We reviewed 829 clinical charts diagnosed of uterine cervix cancer; of this group 316 patients were chosen in stages II b III a and II b. 148 cases in this group (46.8%) received treatment, on the meanwhile 168 (53.2%) left treatment at beginning. 70.27% had been received treatment with exclusivity radiotherapy and 29.73% had been treated with radiotherapy plus rescue surgery. Middle age was 53.11 years. 88.5% in histological finding was predominant squamous cell carcinoma. The majority of cases stage II-b the most frequent was over stages III a, and III b. The patients treated with exclusivity radiotherapy, 47% showed a good response. The group treated with radiotherapy plus rescue surgery; 54% showed preoperative residual tumor and near of 55.5% of this group that went through surgical procedure showed tumor persistence after surgery. In this study survival result founded in treated patients of both groups when we stop gathering of data they not showed a consistent difference according to the type's treatment. (The author)

    This study aims to evaluate and to compare the performance of cervical digital photography (CDP) to the visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI) methods for screening the uterine cervix cancer and its precursor lesions in developing countries. A cross-sectional study was performed in Brazil. 176 women were evaluated by VIA, VILI, CDP with acetic acid and CDP with Lugol's iodine. Kappa statistic was used to estimate the interobserver and intermethod agreement. Sensitivity, specificity and diagnostic accuracy of the four methods (VIA, VILI, CDP with acetic acid, CDP with Lugol's iodine) was calculated. Interobserver agreement for CDP with acetic acid was K = 0.441 and for CDP with Lugol's iodine was K = 0.533; intermethod agreement of VIA and CDP with acetic acid, K = 0.559; and of VILI and CDP with Lugol's iodine, K = 0.507. Sensitivity and specificity of CDP with acetic acid were 84.00 and 95.83 %, and of CDP with Lugol's iodine were 88.00 and 97.26 %, respectively. The diagnostic accuracy of CDP with acetic acid and CDP with Lugol's iodine was 92.78 and 94.90 %, respectively. This was the first study to assess the CDP with Lugol's iodine performance, which had similar performance to the CDP with acetic acid. CDP is considered a promising method for screening the uterine cervix cancer and its precursor lesions in developing countries.

    Cancer is a leading cause of morbidity and death in Puerto Rico. To set a baseline for identifying new trends and patterns of cancer incidence, Puerto Rico Central Cancer Registry staff and CDC analyzed data from Puerto Rico included in U.S. Cancer Statistics (USCS) for 2007-2011, the most recent data available. This is the first report of invasive cancer incidence rates for 2007-2011 among Puerto Rican residents by sex, age, cancer site, and municipality. Cancer incidence rates in Puerto Rico were compared with those in the U.S. population for 2011. A total of 68,312 invasive cancers were diagnosed and reported in Puerto Rico during 2007-2011. The average annual incidence rate was 330 cases per 100,000 persons. The cancer sites with the highest cancer incidence rates included prostate (152), female breast (84), and colon and rectum (43). Cancer incidence rates varied by municipality, particularly for prostate, lung and bronchus, and colon and rectum cancers. In 2011, cancer incidence rates in Puerto Rico were lower for all cancer sites and lung and bronchus, but higher for prostate and thyroid cancers, compared with rates within the U.S. Identifying these variations can aid evaluation of factors associated with high incidence, such as cancer screening practices, and development of targeted cancer prevention and control efforts. Public health professionals can monitor cancer incidence trends and use these findings to evaluate the impact of prevention efforts, such as legislation prohibiting tobacco use in the workplace and public places and the Puerto Rico Cessation Quitline in decreasing lung and other tobacco-related cancers.

    Surgical staging in early-stage uterine cancer is controversial. Preoperative serum CA-125 may be of clinical value in predicting the presence of extra-uterine disease in patients with apparent early-stage endometrial cancer. Between October 6, 2005, and June 17, 2010, 760 patients were enrolled in an international, multicentre, prospective randomized trial (LACE) comparing laparotomy with laparoscopy in the management of endometrial cancer apparently confined to the uterus. Of these, 657 patients with endometrial adenocarcinoma had a preoperative serum CA-125 value recorded. Multiple cross-validation analysis was undertaken to correlate preoperative serum CA-125 with stage of disease (Stage I vs. Stage II+) after surgery. Patients' median preoperative serum CA-125 was 14 U/ml. A cutoff point of 30 U/ml was associated with the smallest misclassification error, and using this cutoff, 98 patients (14.9%) had elevated CA-125 levels. Of those, 36 (36.7%) had evidence of extra-uterine disease. Of the 116 patients (17.7%) with evidence of extra-uterine disease, 31.0% had an elevated CA-125 level. On univariate and multivariable logistic regression analysis, only preoperative CA-125 level, but no other preoperative clinical characteristics were found to be associated with extra-uterine spread of disease. Utilizing a cutoff point of 30 U/ml achieved a sensitivity, specificity, positive predictive value and negative predictive value of 31.0, 88.5, 36.7 and 85.7%, respectively. Elevated CA-125 above 30 U/ml in patients with apparent early-stage disease is a risk factor for the presence of extra-uterine disease and may assist clinicians in the management of patients with clinical Stage I endometrial cancer.

    The incidence of cancer varies around the globe, especially between less-developed and developed regions. The aim of this study is to explore differences in cancer incidence between China and the USA. Data were obtained from the GLOBOCAN 2008 database. Estimated numbers of new cancer cases in the USA were obtained from the American Cancer Society, while the numbers of cases in China, including those in urban and rural areas, were obtained from 36 cancer registries (2003-2005). Cancer incidence for major sites between China and the USA were analyzed. In China, lung cancer was the predominant type of cancer detected in males; in females, breast cancer was the main type of cancer. Gastrointestinal cancers, such as those of the liver, stomach, and esophagus, were more commonly seen in China than in the USA. A significant difference in the incidence of melanoma of the skin was observed between China and the USA. During comparison of differences in the age-standardized rates by world population (ASRWs) of major cancer sites between the two countries, 4 sites in males (i.e., nasopharynx, esophagus, stomach, and liver) and 6 sites in females (i.e., nasopharynx, esophagus, stomach, liver, gallbladder, and cervix uteri) showed higher cancer incidence rates in China than in the USA. Significant differences in cancer incidence sites were found between the two countries. Cancer may be prevented through public education and awareness. Programs to promote cancer prevention in China, especially those of the lung, breast, and gastrointestinal region, must also be implemented.

    Cytologic and histologic diagnoses were made on 184 patients with cancer of the uterine cervix treated with radiation therapy. In 125 patients examined at the 8th day after completion of external irradiation, 73 and 52 patients were cytologically positive and negative, respectively, for persistent cancer. Histologically, 74 and 51 patients were positive and negative, respectively. Fifty-eight and 36 patients showed an agreement between the two procedures for positive and negative findings, respectively. In 159 patients examined at the 8th day after both external and intracavitary irradiation, 17 were cytologically diagnosed as positive and 142 as negative: histologically, 53 were positive and 106 were negative. Thirteen and 102 patients showed an agreement between the procedures for positive and negative findings, respectively. Using histological findings as the standard, false negative cases of cytology increased after doing intracavitary irradiation than after external irradiation (25 % vs 13 %). (Namekawa, K.)

    Full Text Available CONTEXT AND OBJECTIVE: Cancer of the uterine cervix is still very common in Brazil. It is important to evaluate factors that influence its prognosis. The aim here was to analyze the prevalence of prognostic anatomoclinical factors among patients with carcinoma of the uterine cervix undergoing radical hysterectomy. DESIGN AND SETTING: Cross-sectional study on 301 patients with invasive carcinoma of the uterine cervix who underwent Level III Piver-Rutledge hysterectomy surgery at São Marcos Hospital. METHODS: The following variables were analyzed: age, histological type, degree of differentiation, invasion of lymphatic, vascular and perineural space, lymph node metastasis, distance to nearest margin, tumor invasion depth, vaginal cuff size, largest diameter of the tumor, presence of necrosis and surgical margin involvement. Descriptive statistics, multiple regression analysis, Kaplan-Meier survival curves and the log-rank test were performed. A significance level of 5% was used. RESULTS: The mean age was 48.27 years. The following were not important for the prognosis, in relation to survival analysis: degree of differentiation and tumor invasion depth; presence of lymphatic, blood and perineural invasions; distance to nearest margin; and vaginal cuff size. Tumor size (P < 0.036, presence of lymph node metastasis (P < 0.0004, necrosis (P < 0.05 and surgical margin involvement (P < 0.0015 presented impacts on survival. The overall survival with 98 months of follow-up was 88.35%. CONCLUSION: The most prevalent prognostic factors were the presence of lymph node metastasis, tumor size and surgical margin involvement.

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic

    The treatment of uterine cervical carcinoma is largely dependent on the tumor stage. Despite significant inaccuracies in the clinical examination, uterine cervical cancer remains the only gynecological form of cancer still largely staged according to clinical findings. Although imaging is still not included in the staging the recently published revised FIGO (Federation International de Gynecologie et d'Obstetrique) system encourages the use of modern cross-sectional imaging (magnetic resonance imaging MRI and computed tomography CT). Due to its high soft tissue contrast MRI allows excellent non-invasive assessment of the cervix with direct tumor delineation as well as assessment of the prognosis based on morphological factors. Studies in the literature report an accuracy of 93% for MRI in the preoperative assessment of tumor size and in the differentiation of operable from advanced cervical cancer. Therefore MRI is considered to be the optimal modality for diagnostic evaluation starting from FIGO stage IB1, for radiation therapy planning, and for exclusion of recurrence in follow-up. In this paper we give an overview of the role of magnetic resonance imaging in preoperative staging of uterine cervical cancer. (orig.) [German] Die Therapieplanung beim Zervixkarzinom ist weitgehend von der Stadieneinteilung nach FIGO (Federation International de Gynecologie et d'Obstetrique) abhaengig, die trotz erheblicher Ungenauigkeiten bei der klinischen Stadieneinteilung weiterhin aufgrund klinischer Untersuchungsbefunde erfolgt. Obwohl bildgebende Verfahren nach wie vor fuer die Stadieneinteilung nicht vorgesehen sind, wird im kuerzlich erschienen revidierten Stagingsystem der FIGO zum ersten Mal die Verwendung moderner Schnittbilddiagnostik (MRT und CT) befuerwortet. Die MRT ermoeglicht dank ihres hohen Weichteilkontrasts ein ausgezeichnetes nichtinvasives Staging des Zervixkarzinoms mit direkter Tumordarstellung sowie einer Prognoseabschaetzung anhand

    To evaluate whether environmental tobacco smoke (ETS) influences breast cancer incidence, data from a population-based case-control study were analyzed. Respondents with available ETS information assessed by in-person questionnaires included 1356 newly diagnosed cases and 1383 controls. Relative to nonsmokers who reported no residential ETS exposure throughout the life course, the odds ratios (OR) for breast cancer were not substantially elevated in relation to ETS exposure, active smoking, or a joint measure of active and passive smoking (OR, 1.15, 95% CI, 0.90, 1.48). An increased OR, however, was noted among nonsmokers who lived with a smoking spouse for over 27 years (2.10, 95% CI, 1.47, 3.02), although no dose-response was evident. Also, among women with hormone-receptor-positive tumors only, the OR for both active and passive smoking was increased (1.42 for ER + PR + , 95% CI, 1.00, 2.00). Our data suggest that if there is an effect for ETS on breast cancer, that effect is restricted to selected subgroups of women, such as those with long-term exposure from a smoking spouse

    A 62-year-old woman who had received extended hysterectomy and radium-needle insertion for cancer of the uterine corpus at 32 years of age. Following that episode, rectal bleeding persisted for several years before it spontaneously cleared up. Rectal bleeding recurred 29 years later, and a small ulcer was revealed radiographically and endoscopically. The surgically resected specimen showed well differentiated adenocarcinoma penetrating the proper muscle layer. The effect of former radiotherapy remained as around the lesion intimal thickening and obstruction of small arteries. (author)

    Full Text Available Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2003, and area-level distribution based on three strategies: i using uncorrected death certificate information; ii correcting estimates of corpus and cervix uteri mortality by fully reallocating unspecified deaths to either one of these categories, and iii partially correcting specified estimates by maintaining as unspecified a fraction of deaths certified as due to cancer of "uterus not otherwise specified". The proportion of uterine cancer deaths without subsite specification decreased from 42.9% in 1984 to 20.8% in 2003. Partial and full corrections resulted in considerable increases of cervix (31.3 and 48.8%, respectively and corpus uteri (34.4 and 55.2% cancer mortality. Partial correction did not change trends for subsite-specific uterine cancer mortality, whereas full correction did, thus representing an early indication of decrease for cervical neoplasms and stability for tumors of the corpus uteri in this population. Ecologic correlations between mortality and socioeconomic indices were unchanged for both strategies of correcting estimates. Reallocating unspecified uterine cancer mortality in contexts with a high proportion of these deaths has a considerable impact on the epidemiologic profile of mortality and provides more reliable estimates of cervix and corpus uteri cancer death rates and trends.

    In the United States, cancer is common, with high morbidity and mortality; cancer incidence varies between states. Online searches reflect public awareness, which could be driven by the underlying regional cancer epidemiology. The objective of our study was to characterize the relationship between cancer incidence and online Google search volumes in the United States for 6 common cancers. A secondary objective was to evaluate the association of search activity with cancer-related public events and celebrity news coverage. We performed a population-based, retrospective study of state-level cancer incidence from 2004 through 2013 reported by the Centers for Disease Control and Prevention for breast, prostate, colon, lung, and uterine cancers and leukemia compared to Google Trends (GT) relative search volume (RSV), a metric designed by Google to allow interest in search topics to be compared between regions. Participants included persons in the United States who searched for cancer terms on Google. The primary measures were the correlation between annual state-level cancer incidence and RSV as determined by Spearman correlation and linear regression with RSV and year as independent variables and cancer incidence as the dependent variable. Temporal associations between search activity and events raising public awareness such as cancer awareness months and cancer-related celebrity news were described. At the state level, RSV was significantly correlated to incidence for breast (r=.18, P=.001), prostate (r=-.27, P<.001), lung (r=.33, P<.001), and uterine cancers (r=.39, P<.001) and leukemia (r=.13, P=.003) but not colon cancer (r=-.02, P=.66). After adjusting for time, state-level RSV was positively correlated to cancer incidence for all cancers: breast (P<.001, 95% CI 0.06 to 0.19), prostate (P=.38, 95% CI -0.08 to 0.22), lung (P<.001, 95% CI 0.33 to 0.46), colon (P<.001, 95% CI 0.11 to 0.17), and uterine cancers (P<.001, 95% CI 0.07 to 0.12) and leukemia (P<.001, 95

    A relation between apparent diffusion coefficient (ADC) values and tumor cellular density has been reported. The purpose of this study was to measure the ADC values of cervical cancers in the uterus and compare them with those of normal cervical tissues, and to test whether ADC could differentiate between normal and malignant cervical tissues in the uterus. Twelve consecutive female patients with cervical cancer of the uterus and ten female patients with other pelvic abnormalities were included in this study. ADC was measured at 1.5 T with b-factors of 0, 300 and 600 s/mm 2 using single-shot echo-planar diffusion-weighted imaging and a parallel imaging technique. The mean ADC value of cervical cancer lesions was 1.09±0.20 x 10 -3 mm 2 /s, and that of normal cervix tissue was 1.79±0.24 x 10 -3 mm 2 /s (P<0.0001). In nine patients treated by chemotherapy and/or radiation therapy, the mean ADC value of the cervical cancer lesion increased significantly after therapy (P<0.001). The present study showed, with a small number of patients, that ADC measurement has a potential ability to differentiate between normal and cancerous tissue in the uterine cervix. Further study is necessary to determine the accuracy of ADC measurement in monitoring the treatment response. (orig.)

    Efficacy, survival rates and adverse effects of the combined therapy of irradiation with intravaginal bleomycin suppositories were analyzed and discussed in 49 patients with uterine cervical cancer. The results were as follows: 1. Histological examination of biopsy specimens from the uterine cervix taken just after the completion of this treatment showed favorable control over the primary lesions. However, the efficacy of the bleomycin suppositories was too mild to form a basis for treatment without intracavitary irradiation. Because of the low concentration of bleomycin in serum after suppository administration, it is thought that bleomycin would have little effect on distant metastases. 2. Survival rates in stage III patients were 83% at 12 months, 77% at 24 months and 70% at 36 months. These were superior to those for irradiation alone. 3. The major adverse effect of bleomycin suppositories was fever, reduction of the bleomycin dose in each suppository but controlled this to some extent Lung fibrosis or severe damage to the liver, kidney and bone marrow were not found.

    Today around 275000 women a year in the world keep dying from the cancer of uterine cervix due to the difficulty to meet the logistic requirements of an organized screening in the developing world. Polarimetric imaging is a new promising technique with a tremendous potential for applications in biomedical diagnostics: it is sensitive to slight morphological changes in tissues, can provide wide field images for the screening and requires light sources such as a LED for example. This work intends to characterize the polarimetric response of the uterine cervix in its healthy and pathological states. An extensive series of ex-vivo measurements is in progress the Kremlin Bicêtre hospital near Paris using an imaging multispectral Mueller polarimeter in backscattering configuration. The goal of this study is to evaluate the performances of polarimetric imaging technique in terms of sensitivity and specificity for the detection of healthy epithelia (Healthy Squamous epithelium and Malpighian Metaplasia) with respect to the diagnosis provided by pathologists from histology slides as the "gold standard". We show that, at λ=550nm, performances as high as 62% sensitivity and 64% specificity are achieved by optimizing a simple threshold on the scalar retardance values.

    Pap smears are the most common and inexpensive screening method for cervical cancer. We analyzed micronucleus prevalence in exfoliated cervical mucosa cells, to investigate associations between increased numbers of micronuclei and risk factors for cervical cancer. Analytical cross-sectional study, at Instituto de Pesquisa em Oncologia (IPON). Exfoliated cervical cells were obtained from 101 patients between September 2004 and November 2005. Patients' ages, habits (passive or active smoking, alcoholism and numbers of sexual partners), age at first sexual intercourse, contraceptive methods used, histories of sexually transmitted diseases, use of hormone replacement therapy, numbers of pregnancies and abortions, inflammatory cytology and cervical intraepithelial neoplasia (CIN) were obtained. Cells were collected using Ayre spatulas, transferred to vials containing 0.9% saline solution for micronucleus tests and analyzed at 1000x magnification. The number of micronuclei in 1,000 epithelial cells per patient sample was counted. Comparisons between groups with active (7.9 +/- 7.8) and passive (7.2 +/- 10.6) smoking versus no smoking (3.7 +/- 5.1); with/without alcoholism (7.8 +/- 1.4 and 6.9 +/- 10.1); with/without inflammatory cytology (10.7 +/- 10.5 and 1.3 +/- 1.7); and with CIN I, II and III and no CIN (respectively 4.3 +/- 4.3, 10.6 +/- 5.3, 22.7 +/- 11.9 and 1.3 +/- 1.4) found elevated micronucleus prevalence (P < 0.05). We concluded that the prevalence of micronuclei in exfoliated uterine cervical cells was greater in patients with one or more risk factors for uterine cervical cancer than in patients without risk factors.

DESIGN AND SETTING: Analytical cross-sectional study, at Instituto de Pesquisa em Oncologia (IPON. METHODS: Exfoliated cervical cells were obtained from 101 patients between September 2004 and November 2005. Patients' ages, habits (passive or active smoking, alcoholism and numbers of sexual partners, age at first sexual intercourse, contraceptive methods used, histories of sexually transmitted diseases, use of hormone replacement therapy, numbers of pregnancies and abortions, inflammatory cytology and cervical intraepithelial neoplasia (CIN were obtained. Cells were collected using Ayre spatulas, transferred to vials containing 0.9% saline solution for micronucleus tests and analyzed at 1000x magnification. The number of micronuclei in 1,000 epithelial cells per patient sample was counted. RESULTS: Comparisons between groups with active (7.9 ± 7.8 and passive (7.2 ± 10.6 smoking versus no smoking (3.7 ± 5.1; with/without alcoholism (7.8 ± 1.4 and 6.9 ± 10.1; with/without inflammatory cytology (10.7 ± 10.5 and 1.3 ± 1.7; and with CIN I, II and III and no CIN (respectively 4.3 ± 4.3, 10.6 ± 5.3, 22.7 ± 11.9 and 1.3 ± 1.4 found elevated micronucleus prevalence (P < 0.05. CONCLUSIONS: We concluded that the prevalence of micronuclei in exfoliated uterine cervical cells was greater in patients with one or more risk factors for uterine cervical cancer than in patients without risk factors.

    Sporadic colorectal cancer (CRC) is traditionally diagnosed after de sixth decade of life, although a small percentage of cases are diagnosed in patients under 40 years of age, and incidence is increasing. There exists a great volume of controversy regarding clinical outcome of young patients diagnosed with colorectal cancer (CRC) when compared to elder counterparts. Our aims were to evaluate the rate of CRC in young patients, to review the pertaining literature and to discuss outcomes and clinical prognosis. A retrospective review involving patients with CRC was undertaken, focusing on age at diagnosis. The information extracted from this literature review showed a trend towards a decreased incidence in older people with an opposite effect among adolescents and young adults. Moreover, biological aggressiveness in young adults diagnosed with CRC has not been fully recognized, although it is usually diagnosed later and in association with adverse histological features. Besides that, these features don't affect outcome. These apparent increase in CRC incidence among young patients during the last decades raises the need for a greater suspicious when evaluating common symptoms in this group. Thus, educational programs should widespread information for both population and physicians to improve prevention and early diagnosis results. RESUMO O câncer colorretal (CCR) esporádico é tradicionalmente diagnosticado após a sexta década de vida, embora uma pequena porcentagem de casos seja diagnosticada em doentes abaixo dos 40 anos de idade, e a incidência está aumentando. Existe uma grande controvérsia a respeito da evolução clínica de doentes jovens portadores de CCR em comparação aos mais idosos. Os objetivos deste estudo foram avaliar a prevalência de CCR em doentes jovens, rever a literatura pertinente e discutir suas características mais importantes nesta faixa etária. Para tanto realizou-se revisão da literatura envolvendo doentes com CCR com foco na

    Uterine serous cancer (USC) is aggressive, and the majority of recurrent cases are chemoresistant. Because the receptor tyrosine kinase AXL promotes invasion and metastasis of USC and is implicated in chemoresistance in other cancers, we assessed the role of AXL in paclitaxel resistance in USC, determined the mechanism of action, and sought to restore chemosensitivity by inhibiting AXL in vitro and in vivo We used short hairpin RNAs and BGB324 to knock down and inhibit AXL. We assessed sensitivity of USC cell lines to paclitaxel and measured paclitaxel intracellular accumulation in vitro in the presence or absence of AXL. We also examined the role of the epithelial-mesenchymal transition (EMT) in AXL-mediated paclitaxel resistance. Finally, we treated USC xenografts with paclitaxel, BGB324, or paclitaxel plus BGB324 and monitored tumor burden. AXL expression was higher in chemoresistant USC patient tumors and cell lines than in chemosensitive tumors and cell lines. Knockdown or inhibition of AXL increased sensitivity of USC cell lines to paclitaxel in vitro and increased cellular accumulation of paclitaxel. AXL promoted chemoresistance even in cells that underwent the EMT in vitro Finally, in vivo studies of combination treatment with BGB324 and paclitaxel showed a greater than 51% decrease in tumor volume after 2 weeks of treatment when compared with no treatment or single-agent treatments ( P USC.

    Colorectal cancer is the fourth most common cancer in Asia. However, the trends in colorectal cancer incidence by subsite have not been analyzed across Asian countries. We used the most recent, high quality data from 6 cancer registries for two 5-year periods, 1998-2002 and 2003-2007, from Cancer Incidence in Five Continents to estimate colorectal cancer incidence by subsite in 5 Asian countries. Cases with overlapping lesions or otherwise unspecified colon cancer were re-distributed as proximal or distal colon cancer. Age-standardized incidence rates (ASRs) per 100,000 population and incidence rate ratios from 1998 to 2002 to 2003-2007 were calculated for each subsite. For 2003-2007, men in Miyagi, Japan, had the highest ASR for cancer in the proximal colon, distal colon and rectum. Men of Jewish ancestry in Israel had a high ASR for proximal and distal colon cancer, but the lowest ASR for rectal cancer. The proportion of rectal cancer was highest among Korean men (51.39%) and lowest among Israeli women (26.6%). From 1998-2002 to 2003-2007, rectal cancer incidence did not significantly change in most registries, except for men in Miyagi, Japan, and both sexes in Korea. However, during the same period cancer incidence in the proximal and distal colon increased in most registries. In conclusion, there was substantial variation in subsite distributions of colorectal cancer in Asian registries and increases in overall incidence of colorectal cancer could be attributed to increases in colon cancer.

    Glutathione functions as an important antioxidant in the destruction of hydrogen peroxide and lipid peroxides by providing substrate for the glutathione peroxidase and also promotes the ascorbic acid. Glutathione plays a vital role in detoxification of xenobiotics, carcinogens, free radicals and maintenance of immune functions. The study was aimed to determine plasma glutathione as well as erythrocyte glutathione and glutathione peroxidase in patients with invasive cervical carcinoma (n=30) before initiation and after completion of radiotherapy and subsequently, at the time of first three monthly follow-up visit. The levels of plasma glutathione, erythrocyte glutathione and glutathione peroxidase activity were found to be lower in all cervical cancer patients as compared to age matched normal control women. The study indicates a change in antioxidant status in relation with the glutathione system among patients with invasive carcinoma of the uterine cervix. This study also demonstrates the effect of radiation therapy on this antioxidant system. (author)

    In this paper, we discuss the possibility of cytological judgment of radiosensitivity of uterine cervical cancer by comparison between pre- and post-irradiation smears given 1,000 rads by telecobalt external test irradiation. The estimation of radiation effects on nuclei and the cytological presumption of histological typing in pre-irradiation smears have brought about satisfactory results; agreement between histological and cytological judgements of radiosensitivity was about 96.8%. Cytological criteria of good sensitivity are as follows; Disparity in size of chromatin particles and irregular distribution. Irregularity of nuclear membrane with nuclear wrinkling with diminution of thickness of nuclear membrane. Mature squamous cell carcinoma without pearl formation. Those of poor sensitivity are as follows; Existence of many unchanged viable cells and less disturbances of chromatines. Existence of cells exibiting adenocarcinoma and carcinoma of intermediate type. Clusters of cyanophilic cells having lacy, indistinct cell borders. (auth.)

    Perfusion lymphoscintigraphy was performed by subcutaneous injection of 7.4 MBq (0.2mCi) 99m Tc-human serum albumin ( 99m Tc-HSA) on 18 patients with uterine cancer treated by operation and/or irradiation. Radioactivity at the injection site was counted for 3 min at 10 min [a] and at 3 hr [b] after injection, and the clearance of 99m Tc-HSA was defined as (1-[b]/[a]) x 100(%) ([a] and [b] were corrected for decay of the isotope). The clearance in 6 legs with lymphedema was significantly more delayed than that in 16 legs without lymphedema in the patients treated with both surgery and irradiation (16.6 ± 7.7% vs 34.9 ± 9.3%: P 99m Tc-HSA is useful for evaluating patients with lymphedema and for differentiating it from edema caused by other mechanisms.

    Full Text Available Since the beginning of the 1980s, the feminist movement has used a variety of communication strategies to broaden the reach of feminist knowledge, ideas and debates. In the 1990s, when communication has become an even more important scenario for political action, it has become imperative for feminists to diversify, and perfect those strategies. One of the most successful examples of innovative communication strategies, the Campaign for Prevention of Cervical-Uterine Cancer, developed by SOS Corpo in the state of Pernambuco, is analyzed in this essay. The author discusses the campaign’s origins and development of each of its strategies and their impacts on the local policies for combating the disease.

    In vitro double labeling autoradiography for measuring the labeling index, duration of S phase and potential doubling time has been used to assess the effect of a single and fractionated test dose of irradiation in uterine cervix cancer applied in 21 patients. Tumor-labeling index fell significantly in those tumors which had a high labeling index before irradiation, and these cases were found later to exhibit a good radiation response. Duration of S phase which ranged between 9 and 27 hours prior to irradiation was increased. Differences between the potential doubling time and the actual doubling time suggest a massive cell loss in tumors which were, for the most part, of exophytic type. Fractionated irradiation provides more reliable informations than a single dose and is useful for investigation of dynamic changes in the kinetics of an asynchronous cell population.

    Background. Cervical carcinoma is the only gynecological tumor still being staged mainly by clinical examination and only a limited use of diagnostic radiology. Cross sectional imaging is increasingly used as an aid in the staging procedure. We wanted to assess the impact of magnetic resonance imaging (MRI) in addition to the clinical staging of patients with carcinoma of the uterine cervix. Material and methods. A retrospective single-centre analysis of 183 women referred to a tertiary referral centre for gynecological tumors (<= 65 years old) with cervical cancer diagnosed between January 1, 2003 and December 31, 2006 who have undergone an MRI investigation before start of treatment. Patient records were retrospectively reviewed and any change of the planned treatment after the MRI examination was noted. Results. In patients with cervical carcinoma FIGO stage Ia2-IIa treated surgically, the treatment plan was altered due to MRI results in 10/125 patients. In the smaller group of patients with clinically more advanced disease receiving radio-chemotherapy, the treatment plan was altered in 12/58 patients. Reasons for changing the treatment plan after MRI were findings indicating a higher (n = 8) or lower (n = 5) local tumor stage, findings of para aortic nodal disease (n = 4) or difficulty to clinically examine the patient due to obesity (n = 2). MRI was also an aid in deciding whether or not to offer fertility preserving treatment in three cases. Conclusion. The use of MRI affects treatment planning in patients with cancer of the uterine cervix. The impact is more obvious in more advanced stages of disease and in patients who are difficult to examine clinically due to, for example body constitution. The result of MRI is also an aid in deciding whether or not a fertility preserving operation is feasible

    Objective: The registration data of local cancer registries in 2014 were collected by National Central Cancer Registry (NCCR)in 2017 to estimate the cancer incidence and mortality in China. Methods: The data submitted from 449 registries were checked and evaluated, and the data of 339 registries out of them were qualified and selected for the final analysis. Cancer incidence and mortality were stratified by area, gender, age group and cancer type, and combined with the population data of 2014 to estimate cancer incidence and mortality in China. The age composition of standard population of Chinese census in 2000 and Segi's population were used for age-standardized incidence and mortality in China and worldwide, respectively. Results: Total covered population of 339 cancer registries (129 in urban and 210 in rural) in 2014 were 288 243 347 (144 061 915 in urban and 144 181 432 in rural areas). The mortality verified cases (MV%) were 68.01%. Among them, 2.19% cases were identified through death certifications only (DCO%), and the mortality to incidence ratio was 0.61. There were about 3, 804, 000 new cases diagnosed as malignant cancer and 2, 296, 000 cases dead in 2014 in the whole country. The incidence rate was 278.07/100, 000 (males 301.67/100, 000, females 253.29/100, 000) in China, age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population were 190.63/100, 000 and 186.53/100, 000, respectively, and the cumulative incidence rate (0-74 age years old) was 21.58%. The cancer incidence and ASIRC in urban areas were 302.13/100, 000 and 196.58/100, 000, respectively, whereas in rural areas, those were 248.94/100, 000 and 182.64/100, 000, respectively. The cancer mortality in China was 167.89/100, 000 (207.24/100, 000 in males and 126.54/100, 000 in females), age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population were 106.98/100, 000 and 106.09/100, 000, respectively.

  19. Lung cancer incidence and risk factors

    1993-01-01

    The possibility of developing lung cancer (lc) as a consequence of inhaling hot particles from the Chernobyl accident is discussed. The risk from various factors is reviewed in order to assess the rate of contribution for any of them to carcinogenic process. The conclusions are based on data reported by National Centre of Oncology, Sofia (BG). A total of 2873 new cases have been recorded in 1990. The data for the period 1970-1990 show a crude increase for males and tend to stabilization for females. The similar pattern is obtained in other countries and geographic areas with steady rise of lc cases with about 0.5% per year. The contribution of particular risk factor and its interaction with other factors is assessed on the basis of large number of epidemiologic and experimental studies. The risk of cigarette smoking, as the principal cause for lc, is discussed in various aspects - age, duration, possible dropping the habit. The assessment of another risk factor - exposure to relatively high doses of natural radon daughter products - is more complicated. As an occupational hazard in uranium mines radon and its progeny reveals an increase in excess lc incidence. Regarding radon and its daughters as an environmental risk factor in dwellings, no clear positive relationship between exposure and lc incidence has been observed. In this case the assessment for population living in areas with higher concentration of radon products have to rely on data from uranium mines. Non radiation factors as asbestos, ethers, chromates, metallic iron, nickel, beryllium and arsenic, are also considered. The combined effect of all these factors, as well as of pathological cell processes, viruses, malfunctions of immune system, is mentioned as well. The possibility of interpreting the findings from epidemiological studies within the framework of theoretical multistage models of carcinogenic process is pointed out. (author)

    Sirolimus has anti-carcinogenic properties and can be included in maintenance immunosuppressive therapy following kidney transplantation. We investigated sirolimus effects on cancer incidence among kidney recipients. The US transplant registry was linked with 15 population-based cancer registries and national pharmacy claims. Recipients contributed sirolimus-exposed time when sirolimus claims were filled, and unexposed time when other immunosuppressant claims were filled without sirolimus. Cox regression was used to estimate associations with overall and specific cancer incidence, excluding nonmelanoma skin cancers (not captured in cancer registries). We included 32,604 kidney transplants (5687 sirolimus-exposed). Overall, cancer incidence was suggestively lower during sirolimus use (hazard ratio [HR] = 0.88, 95% confidence interval [CI] = 0.70-1.11). Prostate cancer incidence was higher during sirolimus use (HR = 1.86, 95% CI = 1.15-3.02). Incidence of other cancers was similar or lower with sirolimus use, with a 26% decrease overall (HR = 0.74, 95% CI = 0.57-0.96, excluding prostate cancer). Results were similar after adjustment for demographic and clinical characteristics. This modest association does not provide strong evidence that sirolimus prevents posttransplant cancer, but it may be advantageous among kidney recipients with high cancer risk. Increased prostate cancer diagnoses may result from sirolimus effects on screen detection. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

  1. Intravaginal lactic Acid bacteria modulated local and systemic immune responses and lowered the incidence of uterine infections in periparturient dairy cows.

    Full Text Available The objective of this investigation was to evaluate whether intravaginal infusion of a lactic acid bacteria (LAB cocktail around parturition could influence the immune response, incidence rate of uterine infections, and the overall health status of periparturient dairy cows. One hundred pregnant Holstein dairy cows were assigned to 1 of the 3 experimental groups as follows: 1 one dose of LAB on wk -2 and -1, and one dose of carrier (sterile skim milk on wk +1 relative to the expected day of parturition (TRT1; 2 one dose of LAB on wk -2, -1, and +1 (TRT2, and 3 one dose of carrier on wk -2, -1, and +1 (CTR. The LAB were a lyophilized culture mixture composed of Lactobacillus sakei FUA3089, Pediococcus acidilactici FUA3138, and Pediococcus acidilactici FUA3140 with a cell count of 108-109 cfu/dose. Blood samples and vaginal mucus were collected once a week from wk -2 to +3 and analyzed for content of serum total immunoglobulin G (IgG, lipopolysaccharide-binding protein (LBP, serum amyloid A (SAA, haptoglobin (Hp, tumor necrosis factor (TNF, interleukin (IL-1, IL-6, and vaginal mucus secretory IgA (sIgA. Clinical observations including rectal temperature, vaginal discharges, retained placenta, displaced abomasum, and laminitis were monitored from wk -2 to +8 relative to calving. Results showed that intravaginal LAB lowered the incidence of metritis and total uterine infections. Intravaginal LAB also were associated with lower concentrations of systemic LBP, an overall tendency for lower SAA, and greater vaginal mucus sIgA. No differences were observed for serum concentrations of Hp, TNF, IL-1, IL-6 and total IgG among the treatment groups. Administration with LAB had no effect on the incidence rates of other transition cow diseases. Overall intravaginal LAB lowered uterine infections and improved local and systemic immune responses in the treated transition dairy cows.

    The purpose is to evaluate the accuracy of integrated FDG-PET/CT, compared with PET alone, for diagnosis of suspected recurrence of uterine cervical cancer. Fifty-two women who had undergone treatment for histopathologically proven cervical cancer received PET/CT with suspected recurrence. PET-alone and integrated PET/CT images were evaluated by two different experienced radiologists by consensus for each investigation. A final diagnosis was confirmed by histopathology, radiological imaging, and clinical follow-up for over 1 year. Patient-based analysis showed that the sensitivity, specificity, and accuracy of PET/CT were 92.0% (23/25), 92.6% (25/27), and 92.3% (48/52), respectively, while for PET, the corresponding figures were 80.0% (20/25), 77.8% (21/27), and 78.8% (41/52), respectively. PET/CT resolved the false-positive PET results due to hypermetabolic activity of benign/inflammatory lesions and physiological variants, and was able to detect lung metastasis, local recurrence, peritoneal dissemination, para-aortic lymph node metastasis, and pelvic lymph node metastasis missed by PET alone. However, tiny local recurrence and lymph node metastasis could not be detected even by PET/CT. FDG-PET/CT is a useful complementary modality for providing good anatomic and functional localization of sites of recurrence during follow-up of patients with cervical cancer. (orig.)

    Wistar rats are frequently selected for use in carcinogenicity studies because of their advantageous survival rate, which is more favorable than other strains such as the Sprague-Dawley (SD) strain. Uterine and mammary tumors are relatively common spontaneous neoplasms of both strains. We examined the incidence and coincidence of uterine tumors and mammary tumors in control animals of both strains within the RITA database. There was a strong inverse relationship between these tumor types in Wistar rats (p 10%.

    Breast cancer is the most common malignancy in women around the world. Information on the incidence and mortality of breast cancer is essential for planning health measures. This study aimed to investigate the incidence and mortality of breast cancer in the world using age-specific incidence and mortality rates for the year 2012 acquired from the global cancer project (GLOBOCAN 2012) as well as data about incidence and mortality of the cancer based on national reports. It was estimated that 1,671,149 new cases of breast cancer were identified and 521,907 cases of deaths due to breast cancer occurred in the world in 2012. According to GLOBOCAN, it is the most common cancer in women, accounting for 25.1% of all cancers. Breast cancer incidence in developed countries is higher, while relative mortality is greatest in less developed countries. Education of women is suggested in all countries for early detection and treatment. Plans for the control and prevention of this cancer must be a high priority for health policy makers; also, it is necessary to increase awareness of risk factors and early detection in less developed countries.

    Evaluate rates of chemotherapy and radiotherapy delivery in the treatment of uterine carcinosarcoma, and compare clinical outcomes of treated and untreated patients. The National Cancer Database was queried to identify patients diagnosed with uterine carcinosarcoma between 2003 and 2011. The impact of chemotherapy on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. A total of 10,609 patients met study eligibility criteria. Stages I, II, III, and IV disease accounted for 2997 (28.2%), 642 (6.1%), 2037 (19.2%), and 1316 (12.4%) of the study population, respectively. Most patients (91.0%) underwent definitive surgery, and lymphadenectomy was performed in 68.7% of the patients. Chemotherapy was administered in 2378 (22.4%) patients, radiotherapy to 2196 (20.7%), adjuvant chemo-radiation to 1804 (17.0%), and 4231 (39.9%) of women did not received adjuvant therapy. Utilization of chemotherapy became more frequent over time. Over the entire study period, after adjusting for race, period of diagnosis, facility location, facility type, insurance provider, stage, age, treatment modality, lymph node dissection, socioeconomic status, and comorbidity index, there was an association between treatment modality and survival. The lowest hazard ratio observed was in patients that received chemo-radiation. The strongest quantitative predictor of death was stage at the time of diagnosis. In addition, surgical treatment, lymph node dissection, most recent time-periods, lower comorbidity index, and higher socioeconomic status were associated with improved survival. The overall rates of chemotherapy use have increased over time. Adjuvant chemotherapy and chemo-radiation were associated with improved survival. Copyright © 2015 Elsevier Inc. All rights reserved.

    The incidence of skin cancer continues to increase worldwide. The purpose of this study was to determine the incidence of skin cancer in Puerto Rico in a selected year (2005) and to compare these findings with those previously reported for Puerto Rico in 1974 and 1981 and with other countries. The data was collected from the pathology reports corresponding to the period of January to December 2005 of 21 participating Pathology Laboratories throughout Puerto Rico. The rate and distribution of the main types of skin cancer was calculated based on sex, age, anatomic location and laterality. The incidence of skin cancer in Puerto Rico for 2005 was 6,568 cases, which represent a rate of 167.9 per 100,000 inhabitants. The most common type of skin cancer was basal-cell carcinoma. Skin cancer was more common in males except for melanoma, which was more common in females. The incidence increases with age on all types of skin cancer. The head and neck area was the most frequent location, except for melanoma in women, which was more common on the legs. The incidence rate was 41.5/100,000 in 1974, 52.5/100,000 in 1981 and 167.9/100,000 in 2005, a 305% increase. We found an increasing incidence of skin cancer in Puerto Rico when compared with previous reported data. This analysis provides a comprehensive evaluation of the epidemiology of skin cancer in Puerto Rico.

    Different publications show an increased incidence of neoplasms in renal transplant patients. The objective of this study is to determine the incidence of cancer in the recipients of renal transplants performed in the A Coruña Hospital (Spain) during the period 1981–2007. During the study period 1967 kidney transplants were performed, corresponding to 1710 patients. Patients with neoplasms prior to the transplant will be excluded (n = 38). A follow-up study was carried out in order to estimate cancer incidence after transplantation. For each patient, information included donor and recipient characteristics, patients and graft survival and cancer incidence after transplantation. Incident cancer is considered as new cases of cancer after the transplant with anatomopathological confirmation. Their location will be classified according to the ICD-9. The analysis will be calculated using the indirect standardisation method. Age-adjusted cancer incidence rates in the Spanish general population will be obtained from the Carlos III Health Institute, the National Epidemiology Centre of the Ministry of Science and Technology. Crude first, second and third-year post-transplantation cancer incidence rates will be calculated for male and female recipients. The number of cases of cancer at each site will be calculated from data in the clinical records. The expected number of cancers will be calculated from data supplied by the Carlos III Health Institute. For each tumour location we will estimate the standardized incidence ratios (SIRs), using sex-specific cancer incidence rates, by dividing the incidence rate for the transplant patients by the rate of the general population. The 95% confidence intervals of the SIRs and their associated p-values will be calculated by assuming that the observed cancers follow a Poisson distribution. Stratified analysis will be performed to examine the variation in the SIRs with sex and length of follow-up. Competing risk survival analysis

    What's known on the subject? and What does the study add? Increased sun exposure and blood levels of vitamin D have been postulated to be protective against prostate cancer. This is controversial. We investigated the relationship between prostate cancer incidence and solar radiation in non-urban Australia, and found a lower incidence in regions receiving more sunlight. In landmark ecological studies, prostate cancer mortality rates have been shown to be inversely related to ultraviolet radiation exposure. Investigators have hypothesised that ultraviolet radiation acts by increasing production of vitamin D, which inhibits prostate cancer cells in vitro. However, analyses of serum levels of vitamin D in men with prostate cancer have failed to support this hypothesis. This study has found an inverse correlation between solar radiation and prostate cancer incidence in Australia. Our population (previously unstudied) represents the third group to exhibit this correlation. Significantly, the demographics and climate of Australia differ markedly from those of previous studies conducted on men in the United Kingdom and the United States. • To ascertain if prostate cancer incidence rates correlate with solar radiation among non-urban populations of men in Australia. • Local government areas from each state and territory were selected using explicit criteria. Urban areas were excluded from analysis. • For each local government area, prostate cancer incidence rates and averaged long-term solar radiation were obtained. • The strength of the association between prostate cancer incidence and solar radiation was determined. • Among 70 local government areas of Australia, age-standardized prostate cancer incidence rates for the period 1998-2007 correlated inversely with daily solar radiation averaged over the last two decades. •  There exists an association between less solar radiation and higher prostate cancer incidence in Australia. © 2011 THE AUTHORS.

    To evaluate cancer incidence among Minnesota taconite mining workers. We evaluated cancer incidence between 1988 and 2010 in a cohort of 40,720 Minnesota taconite mining workers used between 1937 and 1983. Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were estimated by comparing numbers of incident cancers with frequencies in the Minnesota Cancer Surveillance System. SIRs for lung cancer by histologic subtypes were also estimated. We adjusted for out-of-state migration and conducted a probabilistic bias analysis for smoking-related cancers. A total of 5700 cancers were identified, including 51 mesotheliomas and 973 lung cancers. The SIRs for lung cancer and mesothelioma were 1.3 (95% CI = 1.2-1.4) and 2.4 (95% CI = 1.8-3.2), respectively. Stomach, laryngeal, and bladder cancers were also elevated. However, adjusting for potential confounding by smoking attenuated the estimates for lung (SIR = 1.1, 95% CI = 1.0-1.3), laryngeal (SIR = 1.2, 95% CI = 0.8-1.6), oral (SIR = 0.9, 95% CI = 0.7-1.2), and bladder cancers (SIR = 1.0, 95% CI = 0.8-1.1). Taconite workers may have an increased risk for certain cancers. Lifestyle and work-related factors may play a role in elevated morbidity. The extent to which mining-related exposures contribute to disease burden is being investigated. Copyright © 2015 Elsevier Inc. All rights reserved.

    The aim of this study was to assess cancer incidence in a cohort of woodworkers exposed to softwood dust in a Lithuanian wooden joinery products factory. The study population consisted of 1518 workers (1080 men and 438 women) employed in the factory for at least 1 year between 1947 and 1996 and living in Lithuania on 1 January 1978, when the follow-up for cancer incidence began. The follow-up period for cancer was 1978-2007. Cancer risk was assessed by standardised incidence ratios (SIR) with reference to the national population. Overall cancer incidence was not increased among woodworkers. However, the number of mouth and pharynx cancer cases among male woodworkers was significantly increased compared with expected numbers (SIR 2.19, 95% CI 1.17 to 3.74). A higher risk was found for cancer of the buccal cavity than for pharyngeal cancer (SIRs 2.83 and 1.45, respectively). The SIR for larynx cancer was also elevated (SIR 1.39, 95% CI 0.64 to 2.64) among men, while the number of lung cancer cases was higher than expected only among women (SIR 2.07, 95% CI 00.57 to 5.31). This results of this study support the hypothesis that exposure to softwood dust may increase the risk of oral and pharyngeal cancer. No support was found for an increased risk of other respiratory cancers among workers exposed to softwood dust.

    The aim of this study was to develop an appropriate definition for vaginal cuff and paracolpium clinical target volume (CTV) for postoperative intensity modulated radiation therapy in patients with uterine cervical cancer. A working subgroup was organized within the Radiation Therapy Study Group of the Japan Clinical Oncology Group to develop a definition for the postoperative vaginal cuff and paracolpium CTV in December 2013. The group consisted of 5 radiation oncologists who specialized in gynecologic oncology and a gynecologic oncologist. A comprehensive literature review that included anatomy, surgery, and imaging fields was performed and was followed by multiple discreet face-to-face discussions and e-mail messages before a final consensus was reached. Definitions for the landmark structures in all directions that demarcate the vaginal cuff and paracolpium CTV were decided by consensus agreement of the working group. A table was created that showed boundary structures of the vaginal cuff and paracolpium CTV in each direction. A definition of the postoperative cervical cancer vaginal cuff and paracolpium CTV was developed. It is expected that this definition guideline will serve as a template for future radiation therapy clinical trial protocols, especially protocols involving intensity modulated radiation therapy.

    A case of rectovesicovaginal fistula caused by pelvic radiation for uterine cancer is presented. A 62-year-old woman visited our department complaining of macroscopic hematuria, mictional pain and pollakisuria. She had a history of total hysterectomy and radiation therapy for cervical cancer 26 years earlier. Melena was noted in March 1994 and an escape of stool from the vagina followed nine months later. She consulted a surgeon about it, however no active treatment was performed before coming under our care. Computed tomography demonstrated that the posterior bladder wall was extremely thin and the possibility of the formation of vesical perforation was strongly suggested. We constructed transverse-colostomy, however, a rectovesicovaginal fistula developed seven months later. Therefore, in order to regain a dry life, an ileal conduit was constructed and her quality of life began to improve. It is probable that the rectovesicovaginal fistula could have been prevented if colostomy had been carried out soon after the appearance of melena or soon after the formation of the rectovaginal fistula.

    In order to investigate the effects of Quercetin on radiosensitivity of human Uterine Cervix Cancer HeLa cells, MTT assay and clonogenic assay were performed to evaluate the cytotoxicity of Quercetin on the cells. Clonogenic assay was used to observe its effects on the radiosensitivity of the cells. MTT result shows that the inhibition of Quercetin on the cells is in the dose-dependent and time-dependent. And the clonogenic assay result shows that the effect of Quercetin on HeLa cells can be divided into two parts, one for the inhibition of HeLa cells and another for the induction of HeLa cell death. The other clonogenic assay result also shows Quercetin can decrease clonogenic survival rate of HeLa cells exposed to X rays. The study shows Quercetin might enhance the radiosensitivity of the HeLa cell line. And it may provide a useful evaluation to combination of ionizing radiation and Quercetin for cancer patients.

    The incidence of thyroid cancer in the United States has increased rapidly and Pennsylvania is the state with the highest rate of thyroid cancer in the country, although the factors driving this increase are unknown. Moreover, it remains unclear whether the increase in thyroid cancer represents a true increase in disease or is the result of overdiagnosis. To compare the increase in thyroid cancer incidence and tumor characteristics in Pennsylvania with the rest of the United States and gain insight into the factors influencing the increased incidence of thyroid cancer. In a population-based study, data on thyroid cancer from the Surveillance Epidemiology and End Results 9 (SEER-9) registry and the Pennsylvania Cancer Registry (PCR) from 1985 through 2009 were collected and reviewed for information regarding sex, race, histologic type of thyroid cancer, staging, and tumor size at diagnosis. International Classification of Diseases for Oncology, Third Edition code C739 (thyroid carcinoma) was used to identify 110,615 records in the SEER-9 registry and 29,030 records in the PCR. Average annual percent change (AAPC) in thyroid cancer incidence across various demographic groups in Pennsylvania. The AAPC for thyroid cancer in Pennsylvania was 7.1% per year (95% CI, 6.3%-7.9%) vs 4.2% (95% CI, 3.7%-4.7%) per year in the remainder of the United States, and trends in incidence were significantly different (P Pennsylvania than in the rest of the nation, as is the rate of tumors that are larger and higher stage at diagnosis. These findings suggest that rising disease burden has contributed to the increased incidence of thyroid cancer. Etiologic factors promoting the rise in thyroid cancer in Pennsylvania must be investigated and may provide insight into the drivers of the national increase in thyroid cancer.

    Full Text Available Objective. This study assesses the role of preoperative serum CA125 levels in the planning treatment options for women diagnosed with uterine cancer. Material and Method. Ninety five consecutive patients diagnosed with uterine cancer during a four-year period were identified. Age ranged from 35 to 89 years with a mean age of 69 years. The preoperative CA125 levels were dichotomised at 28 U/mL (using ROC analysis to identify the best discriminating threshold for 5-year survival. This level was then correlated with preoperative prognostic indicators: patient age, tumour grade, and histopathological tumour cell type. Survival data was plotted using Kaplan-Meier curves and analysed using the log-rank test. Univariate and multivariate analysis were performed to identify the predictors of overall survival. Results. The mean age of patients was 69 years (range: 35–89. On univariate analysis, the use of preoperative CA125 levels of greater or less than 28 U/mL correlated significantly with age (P=0.01, the grade of disease (P=0.02 and unfavourable tissue type (P=0.03. This threshold CA125 level had a sensitivity of 75%, specificity of 76%, positive predictive value of 35% and negative predicative value of 96.25%, and a likelihood ratio of 3.12 for predicting nodal disease. Using a threshold of preoperative CA125 level of 28 U/mL (area under curve: 0.60 was also a significant predictor of 5-year survival (log-rank test, P=0.01. Using Cox multivariate survival analysis to identify predictive preoperative factors overall, unfavourable cell type was the strongest predictor of survival (Chi square = 36.5, df = 4, and P=0.001, followed by preoperative CA125 level (CA125 > 28 U/mL, P=0.011 and unfavourable preoperative grade (P=0.017. Amongst patients with a favourable histological tissue type (endometrioid, preoperative CA125 levels predicted overall survival (Chi square = 6.039, df = 2, P=0.02; however unfavourable preoperative

    To assess the incidence and multiplicity of keratinocyte cancers (basal cell carcinoma [BCC] and squamous cell carcinoma [SCC]) excised in Australia, and to examine variations by age, sex, state, and prior skin cancer history. Analysis of individual-level Medicare data for keratinocyte cancer treatments (identified by eight specific MBS item codes) during 2011-2014. Histological data from the QSkin prospective cohort study were analysed to estimate BCC and SCC incidence. A 10% systematic random sample of all people registered with Medicare during 1997-2014. People aged at least 20 years in 2011 who made at least one claim for any MBS medical service during 2011-2014 (1 704 193 individuals). Age-standardised incidence rates (ASRs) and standardised incidence ratios (SIRs). The person-based incidence of keratinocyte cancer excisions in Australia was 1531 per 100 000 person-years; incidence increased with age, and was higher for men than women (SIR, 1.43; 95% CI, 1.42-1.45). Lesion-based incidence was 3154 per 100 000 person-years. The estimated ASRs for BCC and SCC were 770 per 100 000 and 270 per 100 000 person-years respectively. During 2011-2014, 3.9% of Australians had one keratinocyte cancer excised, 2.7% had more than one excised; 74% of skin cancers were excised from patients who had two or more lesions removed. Multiplicity was strongly correlated with age; most male patients over 70 were treated for multiple lesions. Keratinocyte cancer incidence was eight times as high among people with a prior history of excisions as among those without. The incidence and multiplicity of keratinocyte cancer in Australia are very high, causing a large disease burden that has not previously been quantified.

    Individual environmental exposures are associated with cancer development; however, environmental exposures occur simultaneously. The Environmental Quality Index (EQI) is a county-level measure of cumulative environmental exposures that occur in 5 domains. The EQI was linked to county-level annual age-adjusted cancer incidence rates from the Surveillance, Epidemiology, and End Results (SEER) Program state cancer profiles. All-site cancer and the top 3 site-specific cancers for male and female subjects were considered. Incident rate differences (IRDs; annual rate difference per 100,000 persons) and 95% confidence intervals (CIs) were estimated using fixed-slope, random intercept multilevel linear regression models. Associations were assessed with domain-specific indices and analyses were stratified by rural/urban status. Comparing the highest quintile/poorest environmental quality with the lowest quintile/best environmental quality for overall EQI, all-site county-level cancer incidence rate was positively associated with poor environmental quality overall (IRD, 38.55; 95% CI, 29.57-47.53) and for male (IRD, 32.60; 95% CI, 16.28-48.91) and female (IRD, 30.34; 95% CI, 20.47-40.21) subjects, indicating a potential increase in cancer incidence with decreasing environmental quality. Rural/urban stratified models demonstrated positive associations comparing the highest with the lowest quintiles for all strata, except the thinly populated/rural stratum and in the metropolitan/urbanized stratum. Prostate and breast cancer demonstrated the strongest positive associations with poor environmental quality. We observed strong positive associations between the EQI and all-site cancer incidence rates, and associations differed by rural/urban status and environmental domain. Research focusing on single environmental exposures in cancer development may not address the broader environmental context in which cancers develop, and future research should address cumulative environmental

    To evaluate and analyze ovary cancer incidence and mortality in China in 2011 using ovary cancer data from population-based cancer registration in China, and to provide scientific information for its control and prevention. Invasive cases of ovary cancer were extracted and analyzed from the overall Chinese cancer database in 2011, which were based on data from 177 population-based cancer registries distributing in 28 provinces. The crude, standardized, and truncated incidences and mortalities et al. were calculated and new and deaths cases from ovary cancer throughout China and in different regions in 2011 were estimated using Chinese practical population. The estimates of new ovary cancer cases and deaths were 45,223 and 18,430, respectively, in China in 2011. The crude incidence rate, age-standardized rate by Chinese standard population (ASR-C) and age-standardized rate by world standard population (ASR-W) incidence were 6.89/100,000, 5.35/100,000 and 5.08/100,000, respectively; the crude, ASR-C and ASR-W mortalities were 2.81/100,000, 2.01/100,000 and 1.99/100,000, respectively. The incidence and mortality in urban areas were higher than those in rural areas. The age-specific incidence and mortality increased rapidly from age 35-39 and peaked at age 60-64 or 75-79 years. After age 45 or 55, the age-specific incidence and death rates in urban were much higher than those in rural areas. Compared with GLOBOCAN 2012 data, the ovary cancer incidence in China in 2011 was at middle level, but its mortality was at low level worldwide.

    The expansion of combination antiretroviral treatment (ART) in southern Africa has dramatically reduced mortality due to AIDS-related infections, but the impact of ART on cancer incidence in the region is unknown. We sought to describe trends in cancer incidence in Botswana during implementation of the first public ART program in Africa. We included 8479 incident cases from the Botswana National Cancer Registry during a period of significant ART expansion in Botswana, 2003-2008, when ART coverage increased from 7.3% to 82.3%. We fit Poisson models of age-adjusted cancer incidence and counts in the total population, and in an inverse probability weighted population with known HIV status, over time and estimated ART coverage. During this period 61.6% of cancers were diagnosed in HIV-infected individuals and 45.4% of all cancers in men and 36.4% of all cancers in women were attributable to HIV. Age-adjusted cancer incidence decreased in the HIV infected population by 8.3% per year (95% CI -14.1 to -2.1%). However, with a progressively larger and older HIV population the annual number of cancers diagnosed remained constant (0.0% annually, 95% CI -4.3 to +4.6%). In the overall population, incidence of Kaposi's sarcoma decreased (4.6% annually, 95% CI -6.9 to -2.2), but incidence of non-Hodgkin lymphoma (+11.5% annually, 95% CI +6.3 to +17.0%) and HPV-associated cancers increased (+3.9% annually, 95% CI +1.4 to +6.5%). Age-adjusted cancer incidence among individuals without HIV increased 7.5% per year (95% CI +1.4 to +15.2%). Expansion of ART in Botswana was associated with decreased age-specific cancer risk. However, an expanding and aging population contributed to continued high numbers of incident cancers in the HIV population. Increased capacity for early detection and treatment of HIV-associated cancer needs to be a new priority for programs in Africa.

    In recent years, cancer case counts in the U.S. underwent a large, rapid decline-an unexpected change given population growth for older persons at highest cancer risk. As these declines coincided with the Great Recession, we examined whether they were related to economic conditions. Using California Cancer Registry data from California's 30 most populous counties, we analyzed trends in cancer incidence during pre-recession (1996-2007) and recession/recovery (2008-2012) periods for all cancers combined and the ten most common sites. We evaluated the recession's association with rates using a multifactorial index that measured recession impact, and modeled associations between case counts and county-level unemployment rates using Poisson regression. Yearly cancer incidence rate declines were greater during the recession/recovery (3.3% among males, 1.4% among females) than before (0.7 and 0.5%, respectively), particularly for prostate, lung, and colorectal cancers. Lower case counts, especially for prostate and liver cancer among males and breast cancer, melanoma, and ovarian cancer among females, were associated with higher unemployment rates, irrespective of time period, but independent of secular effects. The associations for melanoma translated up to a 3.6% decrease in cases with each 1% increase in unemployment. Incidence declines were not greater in counties with higher recession impact index. Although recent declines in incidence of certain cancers are not differentially impacted by economic conditions related to the Great Recession relative to pre-recession conditions, the large recent absolute declines in the case counts of some cancer may be attributable to the large declines in unemployment in the recessionary period. This may occur through decreased engagement in preventive health behaviors, particularly for clinically less urgent cancers. Continued monitoring of trends is important to detect any rises in incidence rates as deferred diagnoses come to

    Geographic variation in breast cancer incidence across Connecticut was examined according to age and birth cohort -specific groups. We assigned each of 60,937 incident breast cancer cases diagnosed in Connecticut, 1986-2009, to one of 828 census tracts around the state. Global and local spatial statistics estimated rate variation across the state according to age and birth cohorts. We found the global distribution of incidence rates across places to be more heterogeneous for younger women and later birth cohorts. Concurrently, the spatial scan identified more locations with significantly high rates that pertained to larger proportions of at-risk women within these groups. Geographic variation by age groups was more pronounced than by birth cohorts. Geographic patterns of cancer incidence exhibit differences within and across age and birth cohorts. With the continued insights from descriptive epidemiology, our capacity to effectively limit spatial disparities in cancer will improve. Copyright © 2017 Elsevier Ltd. All rights reserved.

    A total of 91 cases of uterine cervical cancer, consisting of 38 cases of carcinoma in situ (CIN III) and 53 cases of stage I-IV cervical cancer, were retrospectively and clinicopathologically analyzed. The standard treatment given to these patients consisted of hysterectomy or conization for CIN III; observation of cases of mild to moderate dysplasia; radical hysterectomy plus pelvic lymph node dissection for stage I and II cervical cancer; and radiotherapy for stage III and IV cervical cancer. Postoperative irradiation consisted of irradiation of the whole pelvis with 40-50 Gy. The patients who were not treated surgically underwent 40 Gy external irradiation of the whole pelvis, followed by an additional 20 Gy with shielding and internal irradiation with an RALS. When lymph node metastasis was present, the nodes were irradiated with 40-50 Gy. The mean age of the 38 patients with CIN III was 45.2 years old, and they were para 0-4. In 24 (63.2%) of them the cancer was detected by cytodiagnosis as part of screening. Radical hysterectomy, simple hysterectomy, and conization were performed in 25 patients, 7 patients, and 6 patients, respectively. No recurrences have been detected, and the survival rate is 100%. The mean age of the 53 patients with cervical cancer stage I-IV was 62.4 years old, and they were para 0-10. There were 25 patients with stage I disease, 15 patients with stage II disease, 6 patients with stage III, and 7 patients with stage IV, and their 5-year survival rate was 82.4%, 68.8%, 66.7%, and 42.9%, respectively. Radioenteritis and radiocystitis occurred as adverse radiation effects. Pathologic factors influencing lymph node metastasis were examined by a multivariate analysis based on the data from 25 patients with stage I and II who underwent hysterectomy. The results of the analysis indicated the importance of screening and the choice of appropriate surgical method/technique, as well as the need for further investigation to determine the effective

    Background Breast cancer is the most common cancer among women. Population‐based cancer registration data from the National Central Cancer Registry were used to analyze and evaluate the incidence and mortality rates in China in 2013, providing scientific information for cancer prevention and control. Methods Pooled data were stratified by area (urban/rural), gender, and age group. National new cases and deaths were estimated using age‐specific rates and the corresponding population in 2013. The Chinese population in 2000 and Segi's world population were used to calculate age‐standardized rates. Results The estimated number of new breast cancer cases was about 278 800 in China in 2013. The crude incidence, age‐standardized rate of incidence by Chinese standard population, and age‐standardized rate of incidence by world standard population were 42.02/100 000, 30.41/100 000, and 28.42/100 000, respectively. The estimated number of breast cancer deaths was about 64 600 in China in 2013. The crude mortality, age‐standardized rate of mortality by Chinese standard population, and age‐standardized rate of mortality by world standard population were 9.74/100 000, 6.54/100 000, and 6.34/100 000, respectively. Both incidence and mortality were higher in urban than in rural areas. Age‐specific breast cancer incidence significantly increased with age, particularly after age 20, and peaked at 50–55 years, while age‐specific mortality increased rapidly after 25 years, peaking at 85+ years. Conclusions Breast cancer is the most common cancer in Chinese women, especially women in urban areas. Comprehensive measures are needed to reduce the heavy burden of breast cancer. PMID:28296260

    Gastric cancer is the fifth most common cancer globally with over 70% of new cases occurring in developing countries. In Morocco, oncologists in Marrakech suspected higher frequency of gastric cancer compared to Casablanca, a city 150 kilometers away. This study calculated age-specific, sex-specific, and total incidence rates of gastric cancer in Marrakech and was compared to the Casablanca population-based cancer registry. Using medical records from Center Hospital University Mohammad VI and reports from 4 main private pathology laboratories in Marrakech, we identified 774 patients for the period 2008-2012. Comparison of rates showed higher age-specific incidence in Marrakech in nearly all age groups for both genders. A higher total incidence in Marrakech than in Casablanca was found with rates of 5.50 and 3.23 per 100,000, respectively. Incidence was significantly higher among males in Marrakech than males in Casablanca (7.19 and 3.91 per 100,000, resp.) and females in Marrakech compared to females in Casablanca (3.87 and 2.58 per 100,000, resp.). Future studies should address possible underestimation of gastric cancer in Marrakech, estimate incidence in other regions of Morocco, and investigate possible risk factors to explain the difference in rates.Gastric cancer is the fifth most common cancer globally with over 70% of new cases occurring in developing countries.

    From May 1991 through September 1992, a total of 17 previously untreated patients with invasive uterine cervix cancer and with intact uterus were treated with mid-dose rate intracavitary therapy administered with a Selectron. Early primary tumor responses for all patients were complete. No acute or subacute radiation injury was observed except one patient with aplastic anemia who developed rectal ulcer. Two patients of Stage IIIb died from tumor because of local, paraaortic lymph node and distant metastases. Our early experience concluded that Selectron MDR can be used for cervix cancer patients as safely and effectively as our previously used high-dose rate machine. (author).

    The aim of the study was to assess the accuracy of the colorectal-cancer incidence estimated from administrative data. Methods. We selected potential incident colorectal-cancer cases in 2004-2005 French administrative data, using two alternative algorithms. The first was based only on diagnostic and procedure codes, whereas the second considered the past history of the patient. Results of both methods were assessed against two corresponding local cancer registries, acting as “gold standards.” We then constructed a multivariable regression model to estimate the corrected total number of incident colorectal-cancer cases from the whole national administrative database. Results. The first algorithm provided an estimated local incidence very close to that given by the regional registries (646 versus 645 incident cases) and had good sensitivity and positive predictive values (about 75% for both). The second algorithm overestimated the incidence by about 50% and had a poor positive predictive value of about 60%. The estimation of national incidence obtained by the first algorithm differed from that observed in 14 registries by only 2.34%. Conclusion. This study shows the usefulness of administrative databases for countries with no national cancer registry and suggests a method for correcting the estimates provided by these data.

    Lung cancer is one of the most common cancers in the world and a major cause of death from cancer. One of the important indicators to compare the prevalence and incidence of the disease is a change in the trend. The aim of this study was to investigate the changes in the incidence of lung cancer in Iran. This study was conducted based on existing data obtained from a national registry of cancer cases and the Disease Management Center of Ministry of Health in Iran. All cases registered in the country were included during 2003-2008. Incidence rates were reported based on the direct method and standard population of World Health Organization. The study also examined the morphology of common lung cancers. Trends in incidence underwent joinpoint regression analysis. Based on the results of this study, 14,403 cases of lung cancer have been recorded of which 10,582 cases were in men and 3,821 in women. Highest incidence rates were observed in the 80-84 age group. Considerable variation across provinces was evident. In females squamous cell carcinoma (SCC) demonstrated a reduction from 24% to 16% of lesions over the period of study, while adenocarcinoma rose from 21% to 29%. In males a similar reduction in SCC was apparent (42% to 29%, again with increase in AC (13 % to 18%). The results show that the increase in the incidence of lung cancer the trend is that more men than women and in men and may be caused by changes in smoking pattern. The incidence of lung cancer in the North West and West provinces was higher than in other regions.

    Objective: to evaluate, by means of magnetic resonance imaging, the standardized field borders in radiotherapy for malignant neoplasm of uterine cervix, and to determine the role of this method in the reduction of possible planning errors related to the conventional technique. Materials and methods: magnetic resonance imaging studies for planning of treatment of 51 patients with uterine cervix cancer were retrospectively analyzed. The parameters assessed were the anterior and posterior field borders on sagittal section. Results: The anterior field border was inappropriate in 20 (39.2%) patients and geographic miss was observed in 37.3% of cases in the posterior border. The inappropriateness of both field borders did not correlate with clinical parameters such as patients' age, tumor staging, histological type and degree. Conclusion: the evaluation of standardized field borders with the use of magnetic resonance imaging has demonstrated high indices of inappropriateness of the lateral field borders, as well as the relevant role of magnetic resonance imaging in the radiotherapy planning for patients with uterine cervix cancer with a view to reduce the occurrence of geographic miss of the target volume.

    Absorbed dose determination is an important step for risk assessment related to an exposure to ionizing radiation. However, physical dosimetry cannot be always performed, principally in the case of retrospective estimates. In this context, the use of bioindicators (biological effects) has been proposed, which defines the so-called biological dosimetry. In particular, scoring of unstable chromosomes aberrations (dicentrics, centric rings and fragments) of peripheral blood lymphocytes, while is the most reliable biological method for estimating individual exposure to ionizing radiation. In this work, blood samples from 5 patients, with cervical uterine cancer, were evaluated after partial-body radiotherapy with a source of 69 Co. For this, conventional cytogenetic method was employed, based on Giemsa coloration and fluorescence in situ hybridization, in order to correlate the frequency of unstable chromosome aberrations of blood lymphocytes with absorbed dose, as a result of the radiotherapy. A good agreement was observed between the frequency of chromosome aberrations scored and the values of dose previously calculated by physical dosimetry during patient's radiotherapy. The results presented in this work point out the importance of concerning analyses of unstable chromosome aberrations as biological dosimeter in the investigation of partial-body exposure to ionizing radiation.

    The subject was 30 cases of cancer of the uterine cervix, which were composed of 13 cases of acute rectitis and 17 cases of delayed rectitis due to radiotherapy. Out of them, 25 cases were treated with radiation, alone and 5 cases were treated with postoperative irradiation. The acute cases were administered Sheriproct alone twice a day (in the morning and in the evening) until symptoms disappeared. The delayed cases were administered two or three suppositories per a day together with antihemorrhagics for one to three weeks, decreasing the administration dose according to severity of symptoms. In the delayed cases, this suppository showed effectiveness in prolapsed hemorrhoids with a recovery rate of 88.9%, and it showed effectiveness in a pain with that of 71.4%. However, this depository showed ineffectiveness in hemorrhage, inhibition of mucous stool, and inhibition of secrete, and these symptoms were generally resistant to this suppository. On the other hand, in the acute cases, this suppository showed ineffectiveness only in prolapsed hemorrhoids with a recovery rate of 63.3%, and it showed marked effectiveness in hemorrhage with that of 100%. It also showed effectiveness in a pain, inhibition of mucose stool, and inhibition of secrete. These symptoms responded well to this suppository. Consequently, use of this drug seemed to be significant in making it possible to perform radiotherapy. (Kanao, N.)

    Troglitazone (TRO), a PPAR-γ agonist, can reduce heat shock protein (HSP) 70 and increase the antioxidant enzymes, such as superoxide dismutase (SOD) and catalase, which might affect thermal sensitivity. Here, we investigated whether TRO modifies thermal sensitivity in uterine cervical cancer cells, which is most commonly treated by hyperthermia (HT). HeLa cells were treated with 5μM TRO for 24 hours before HT at 42 .deg. C for 1 hour. Cell survival was analyzed by clonogenic assay. The expression of HSPs was analyzed by Western blot. SOD and catalase activity was measured and reactive oxygen species (ROS) was measured using 2',7'-dichlorofluorescin diacetate and dihydroethidium. The decreased cell survival by HT was increased by preincubation with TRO before HT. Expression of HSP 70 was increased by HT however, it was not decreased by preincubation with TRO before HT. The decreased Bcl-2 expression by HT was increased by preincubation with TRO. SOD and catalase activity was increased by 1.2 and 1.3 times, respectively with TRO. Increased ROS by HT was decreased by preincubation with TRO. TRO decreases thermal sensitivity through increased SOD and catalase activity, as well as scavenging ROS in HeLa cells.

    Objective: To estimate the incidence and mortality of cervical cancer in China based on the cancer registry data in 2014, collected by the National Central Cancer Registry (NCCR). Methods: There were 449 cancer registries submitted cervical cancer incidence and deaths in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of cervical cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas). The percentage of morphologically verified cases and death certificate-only cases were 86.07% and 1.01%, respectively. The mortality to incidence ratio was 0.30. The estimates of new cases were about 102 000 in China in 2014, with a crude incidence rate of 15.30/100 000. The age-standardized incidence rates by China standard population (ASR China) and world standard population (ASR world) of cervical cancer were 11.57/100 000 and 10.61/100 000, respectively. Cumulative incidence rate of cervical cancer in China was 1.11%. The crude and ASR China incidence rates in urban areas were 15.27/100 000 and 11.16/100 000, respectively, whereas those were 15.34/100 000 and 12.14/100 000 in rural areas. The estimates of cervical cancer deaths were about 30 400 in China in 2014, with a crude mortality rate of 4.57/100 000. The ASR China and ASR world mortality rates were 3.12/100 000 and 2.98/100 000, respectively, with a cumulative mortality rate (0-74 years old) of 0.33%. The crude and ASR China mortality rates were 4.44/100 000 and 2.92/100 000 in urban areas, respectively, whereas those were 4.72/100 000 and 3.39/100 000 in rural areas. Conclusions: There is still a heavy burden of

    Purpose : Radiation therapy(RT) is conventionally standard treatment for locally advanced stage for uterine cervix cancer. Recently to improve treatment results, combined chemotherapy and radiation therapy was tried. We retrospectively analysed our experience of 122 patients. Comparison of the results in 45 patients treated with RT alone and 77 patients treated with RT plus chemotherapy was made. Materials and Methods : from January 1985 to December 1991, 122 patients with cervix cancer were treated with whole pelvic external RT and ICR(34 1 ICR, 77 2 ICR, 11 high dose rate ICR) in our department. Forty five patients were treated with RT alone, and 77 patients were treated with combined plus chemotherapy. Mean age was 58 years(range:29-81). Histologic types were 111 squamous cell carcinoma, large cell carcinoma, 3 adenocarcinoma, and 2 adenosquamous cell carcinoma. According to the FIGO stage 6 had stage IA94.9%, 11 had IIA(9.0%), 37 had IIB(30.3%), 3 had IIA(2.5%), 63 had IIB(51.6%), and 2 had stage IV(1.6%). In 77 patients with RT plus chemotherapy, 36 patients were treated with VBP(vinblastin, bleoycin, cisplainum), 39 patients with cisplatinum plus 5-FU and 2 patients with 5-FU. Results : Complete response after external RT(3960cGy-5500cGy)was achieved in 61 patients(50%). He actuarial 5 year and 9 year survival rate was 57.8% and 53.9%, respectively. Five year actuarial survival rate was 63.1% with RT alone(n=45) and 55.9% with RT plus chemotherapy(n=77). Their 5 year survival rate was 35.5% for 1 course of ICR and 67% for 2 courses of ICR. There was statistically significant advantage of survival with RT alone group who were treated with 2 coursed of ICR and dose to the A point≥8000cGy(4/25 died). In RT plus chemotherapy group, dose response was not seen and there was no difference in 5 year survival between 1 course and 2 course of ICR(50% vs 56.8%), and dose to point A less than 8000cGy and more than 8000 cGy(55.6% vs 55.7%). There was no significant

    Full Text Available Objectives. The general aim was to assess cancer incidence and mortality among the general population of Chukotka in 1997–2010 and to compare it with the population of Russia. Methods. Cancer data were abstracted from the annual statistical reports of the P.A. Hertzen Research Institute of Oncology in Moscow. The annual number and percent of cases, crude and age-standardized cancer incidence (ASIR and mortality (ASMR rates per 100,000 among men and women in the Chukotka Autonomous Okrug were determined for the period 1997–2010 for incidence and 1999–2010 for mortality. Two years’ data were aggregated to generate temporal trends during the period. In age-standardization, the Segi-Doll world standard population used by the International Agency for Research on Cancer was used. Results. The higher incidence and mortality rate of cancer (all sites combined among men compared to women, which was observed in Russia nationally, was reflected also in Chukotka, although the difference between men and women was not statistically significant. Overall, the patterns of cancer sites are similar between Chukotka and Russia, with cancer of the lung/trachea/bronchus and stomach occupying the top ranks among men. Oesophageal cancer is common in Chukotka but not in Russia, whereas prostate cancer is common in Russia but not in Chukotka. Among women, breast cancer is either the commonest or second commonest cancer in terms of incidence or mortality in both Chukotka and Russia. Cancer of the lung/trachea/bronchi ranks higher in Chukotka than in Russia. The rate of cancer incidence and mortality for all sites combined during the 13-year period was relatively stable in Russia. Dividing the period into two halves, an increase among both men and women was observed in Chukotka for all sites combined, and also for colorectal cancer. Conclusions. This paper presents previously unavailable cancer epidemiological data on Chukotka. They provide a basis for comparative

    Objective: To estimate the incidence and mortality of female breast cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR), and to provide support data for breast cancer prevention and control in China. Methods: There were 449 cancer registries submitting female breast cancer incidence and deaths data occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of female breast cancer were estimated.

Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas) in 2014. The morphology verified cases (MV%) accounted for 87.42% and 0.59% of incident cases were identified through death certifications only (DCO%), with mortality to incidence ratio of 0.24. The estimates of new breast cancer cases were about 278 900 in China in 2014, accounting for 16.51% of all new cases in female. The crude incidence rate, age-standardized rate of incidence by Chinese standard population (ASRIC), and age-standardized rate of incidence by world standard population (ASRIW) of breast cancer were 41.82/100 000, 30.69/100 000, and 28.77/100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 3.12%. The crude incidence rates and ASRIC in urban areas were 49.94 per 100 000 and 34.85 per 100 000, respectively, whereas those were 31.72 per 100 000 and 24.89 per 100 000 in rural areas. The estimates of breast cancer deaths were about 66 000 in China in 2014, accounting for 7.82% of all the cancer-related deaths in female.

    Cowden syndrome (CS) is an autosomal dominant disorder characterized by multiple hamartomas in the breast, thyroid and endometrium, with a prevalence of 1 per 250,000. Females with CS have a 21–28% lifetime risk of developing uterine cancer. Germline mutations in the phosphatase and tensin homolog (PTEN) gene, a tumor suppressor gene, are responsible for 30–80% of CS cases. PTEN is a nine-exon gene, located on chromosome 10q23.3, which encodes the 403 amino acid PTEN protein. It negatively regulates the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin pathway, affecting various cellular processes and signaling pathways. The present study examined whether PTEN mutations are present in CS-like families with uterine cancer (UC). UC patients underwent surgery at Karolinska University Hospital, Stockholm, Sweden (2008–2012). Pedigrees were analyzed and 54 unrelated CS-like families were identified. CS-like families were defined as having at least one occurrence of uterine cancer and one of breast cancer, as well as at least one additional Cowden-associated tumor (uterine, breast, thyroid, colon or kidney cancer) in the same individual or in first-degree relatives. Genomic DNA was amplified using polymerase chain reaction, and DNA sequencing analysis of all nine exons of the PTEN gene was conducted. No germline PTEN mutations or polymorphisms were identified. Germline PTEN mutations are rare in CS-like families with uterine cancer, therefore, genetic screening must be restricted to patients that meet the strict National Comprehensive Cancer Network criteria. Gynecologists must be aware of the CS criteria and identify potential cases of CS in females where uterine cancer is the sentinel cancer. PMID:25789042

    The National Cancer Registry of Mongolia began as a hospital-based registry in the early 1960s but then evolved to have a population-wide role. The Registry provides the only cancer data available from Mongolia for international comparison. The descriptive data presented in this report are the first to be submitted on cancer incidence in Mongolia to a peer-reviewed journal. The purpose was to describe cancer incidence and mortality for all invasive cancers collectively, individual primary sites, and particularly leading sites, and consider cancer control opportunities. This study includes data on new cancer cases registered in Mongolia in 2003-2007. Incidence and mortality rates were calculated as mean annual numbers per 100,000 residents. Age-standardized incidence (ASR) and age-standardized mortality (ASMR) rates were calculated from age-specific rates by weighting directly to the World Population standard. Between 2003 and 2007, 17,271 new cases of invasive cancer were recorded (52.2% in males, 47.7% in females). The five leading primary sites in males were liver, stomach, lung, esophagus, and colon/rectum; whereas in females they were liver, cervix, stomach, esophagus and breast. ASRs were lower in females than males for cancers of the liver at 63.0 and 99.1 per 100,000 respectively; cancers of the stomach at 19.1 and 42.1 per 100,000 respectively; and cancers of the lung at 8.3 and 33.2 per 100,000 respectively. Liver cancer was the most common cause of death in each gender, the ASMR being lower for females than males at 60.6 compared with 94.8 per 100,000. In females the next most common sites of cancer death were the stomach and esophagus, whereas in males, they were the stomach and lung. Available data indicate that ASRs of all cancers collectively have increased over the last 20 years. Rates are highest for liver cancer, at about four times the world average. The most common cancers are those with a primary site of liver, stomach and esophagus, for which

    American Seventh-day Adventists have been reported to have lower cancer mortality and incidence than the general population. Adventists do not consume tobacco, alcohol or pork, and many adhere to a lacto-ovo-vegetarian lifestyle. Baptists discourage excessive use of alcohol and tobacco. In this study, we investigated whether the incidence of cancer in a large cohort of Danish Adventists and Baptists was different compared to the general Danish population. We followed 11,580 Danish Adventists and Baptists in the nationwide Danish Cancer Registry, which contains information on cases of cancer for 1943-2008. Cancer incidence in the cohort was compared with that in the general Danish population as standardized incidence ratios (SIRs) with 95% confidence intervals (CIs), and within-cohort comparisons were made with a Cox model. Lower cancer incidences were observed for both Seventh-day Adventist men (SIR, 66; 95% CI, 60-72) and women (85; 80-91). The same result was observed for Baptists although not as low. The differences were most pronounced for smoking-related cancers such as those of the buccal cavity and lung (SIR, 20; 13-30 for Seventh-day Adventist men and 33; 22-49 for Seventh-day Adventist women). The incidences of other lifestyle-related cancers, such as of stomach, rectum, liver and cervix, were also decreased. In general, the SIRs were lower for men than for women, and Adventists had lower hazard rates than Baptists. Our findings point to the benefits of compliance with public health recommendations and indicate that lifestyle changes in the population might change the cancer risks of individuals.

    Very high levels of airborne particles have been detected in the subway system in Stockholm. Subway particles are more toxic to DNA in cultured human lung cells than particles from ambient air. This cohort comprised all men in Stockholm County who were gainfully employed in 1970. They were followed for cancer incidence until 1989. Lung cancer cases were identified from the national cancer register. Subway drivers were identified from the census in 1970. The reference cohort comprised all transport and communication workers in Stockholm. There were nine cases of lung cancer among the subway drivers, giving a SIR of 0.82 (95% confidence interval 0.38-1.56). The lung cancer incidence was not increased among the subway drivers. The study gives some evidence against the hypothesis that subway particles would be more potent in inducing lung cancer than particles in ambient air. (c) 2008 Wiley-Liss, Inc.

    A high number of cases of cholangiocarcinoma, a rare form of bile duct cancer, as well as high rates of other cancers were reported by a physician working in Fort Chipewyan, Alberta in 2006. Concerns were raised by local residents, attributing cancers in their community to environmental contamination from a range of industrial development including the oil sands development, uranium mining and pulp mills. However, an initial review of the Alberta Cancer Registry did not confirm an increased incidence of cancer in Fort Chipewyan. In the summer/fall of 2007, a working group was formed to support the Alberta Cancer Board in doing a cluster investigation based on the guidelines of the United States Centre for Disease Control and Prevention. This report presented an investigation to determine if there was an elevated rate of cholangiocarcinoma in Fort Chipewyan and whether there was an elevated rate of cancers overall in Fort Chipewyan. The report provided background information on the Athabasca oil sands, uranium mining, and Fort Chipewyan as well as previous investigations of cancer incidence in Fort Chipewyan. Study methods were also presented with particular reference to study and comparison populations; cancer classification and inclusion criteria; active case ascertainment and verification; methods of analysis; and ethical approval. Results were also presented. The specific cancers that were discussed were cholangiocarcinoma, leukemia, colon cancer, and cancer in First Nations in Alberta. It was concluded that the observed number of cases of cholangiocarcinoma was within the expected range. 121 refs., 12 tabs., 3 figs., 5 appendices.

    The aim of this study is to analyze the relationship between the incidence of breast cancer and income per capita across countries. Data on breast cancer incidence in 52 countries were obtained from GLOBOCAN, along with economic indicators of gross domestic product per capita from the World Bank. Number of computed tomography scanners and magnetic resonance imaging (from World Health Organization) were used as a surrogate for technology and access to screening for cancer diagnosis. Statistical analyses for correlation and regression were performed, along with an analysis of variance (ANOVA). A strong positive association between breast cancer incidence and gross domestic product per capita, Pearson's r = 65.4 %, controlling latitude, density of computed tomography scanners and magnetic resonance imaging was found in countries of temperate zones. The estimated relationship suggests that 1 % higher gross domestic product per capita, within the temperate zones (latitudes), increases the expected age-standardized breast cancer incidence by about 35.6 % (p nations may have a higher incidence of breast cancer independent of geographic location and screening technology.

    Full Text Available Gastric cancer is the fifth most common cancer globally with over 70% of new cases occurring in developing countries. In Morocco, oncologists in Marrakech suspected higher frequency of gastric cancer compared to Casablanca, a city 150 kilometers away. This study calculated age-specific, sex-specific, and total incidence rates of gastric cancer in Marrakech and was compared to the Casablanca population-based cancer registry. Using medical records from Center Hospital University Mohammad VI and reports from 4 main private pathology laboratories in Marrakech, we identified 774 patients for the period 2008–2012. Comparison of rates showed higher age-specific incidence in Marrakech in nearly all age groups for both genders. A higher total incidence in Marrakech than in Casablanca was found with rates of 5.50 and 3.23 per 100,000, respectively. Incidence was significantly higher among males in Marrakech than males in Casablanca (7.19 and 3.91 per 100,000, resp. and females in Marrakech compared to females in Casablanca (3.87 and 2.58 per 100,000, resp.. Future studies should address possible underestimation of gastric cancer in Marrakech, estimate incidence in other regions of Morocco, and investigate possible risk factors to explain the difference in rates.

    Epidemiologic studies on testicular cancer have focused primarily on European countries. Global incidence and mortality have been less thoroughly evaluated. Our goal was to gain a better understanding of the most recent global age-standardized incidence and mortality rates for testicular cancer and to use these values to estimate a region's health care quality. Age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) for testicular cancer were obtained for men of all ages in 172 countries by using the GLOBOCAN 2008 database, reflecting the annual rate of cancer incidence and mortality per 100,000 men. These data were evaluated on a regional level to compare incidence and mortality rates. Global plots of these values were constructed to better visualize geographic distributions. Finally, the ratio of ASIR to ASMR was calculated as a method to assess each region's proficiency in diagnosing and effectively treating testicular cancer. ASIR and ASMR were analyzed by region, and each region's ratio of ASIR to ASMR was calculated. Testicular cancer ASIR is highest in Western Europe (7.8%), Northern Europe (6.7%), and Australia (6.5%). Asia and Africa had the lowest incidence (ASMR was highest in Central America (0.7%), western Asia (0.6%), and Central and Eastern Europe (0.6%). Mortality was lowest in North America, Northern Europe, and Australia (0.1-0.2%). The ASIR-ASMR ratio was highest in Australia (65.0%) and lowest in western Africa (1.0%). National reporting systems varied by country, and data quality may have fluctuated between regions. Testicular cancer incidence remains highest in developed nations with primarily Caucasian populations. Variable ASIR-ASMR ratios suggest markedly different geographic-specific reporting mechanisms, access to care, and treatment capabilities. Copyright © 2011 European Association of Urology.

    Objective This ecologic study tested the hypothesis that census tracts with elevated groundwater uranium and more frequent groundwater use have increased cancer incidence. Methods Data sources included: incident total, leukemia, prostate, breast, colorectal, lung, kidney, and bladder cancers (1996–2005, SC Central Cancer Registry); demographic and groundwater use (1990 US Census); and groundwater uranium concentrations (n = 4,600, from existing federal and state databases). Kriging was used to predict average uranium concentrations within tracts. The relationship between uranium and standardized cancer incidence ratios was modeled among tracts with substantial groundwater use via linear or semiparametric regression, with and without stratification by the proportion of African Americans in each area. Results A total of 134,685 cancer cases were evaluated. Tracts with ≥50% groundwater use and uranium concentrations in the upper quartile had increased risks for colorectal, breast, kidney, prostate, and total cancer compared to referent tracts. Some of these relationships were more likely to be observed among tracts populated primarily by African Americans. Conclusion SC regions with elevated groundwater uranium and more groundwater use may have an increased incidence of certain cancers, although additional research is needed since the design precluded adjustment for race or other predictive factors at the individual level.

    Breast cancer is the most common non-skin cancer amongst women worldwide and is the fifth leading cause of cancer-related mortality overall. It is also the foremost reason for cancer-related mortality in Hispanic females in the United States (US). Although the current incidence of breast cancer is significantly lower in Hispanics compared to that of non-Hispanic Whites (NHW) and Blacks, (91.9, 128.1, and 124.3 per 100,000, respectively, annually), this may increase if Hispanics develop similar lifestyle behaviors to other American women, in categories such as weight management, age at first birth, number of children, and breastfeeding habits. Stage-for-stage mortality for Hispanics is similar to NHWs, but the mortality rate is not declining as rapidly in this ethnic group. Hispanic women share many of the same risk factors for developing breast cancer as NHWs and Blacks. This suggests that many of the risk reduction strategies used in other racial populations may also benefit this group. Providing education about breast cancer and implementing risk reduction strategies in culturally-aware environments could help keep incidence low and reduce cancer-related mortality. Since Hispanics are the largest minority group in the US, this could have a significant impact on the incidence and mortality nationally.

    Gastric cancer is the fourth most common malignancy worldwide. The incidence trends and mortality rates of gastric cancer in Israel have not been studied in depth. The aim of our study was to try and investigate the aforementioned issues in Israel in different ethnic groups. This retrospective study is based on the data of The Israel National Cancer Registry and The Central Bureau of Statistics. Published data from these two institutes were collected, summarized, and analyzed in this study. Around 650 new cases of gastric cancer are diagnosed yearly in Israel. While we noticed a decline during the period 1990-2007 in the incidence in the Jewish population (13.6-8.9 and 6.75-5.42 cases per 100,000 in Jewish men and women, respectively), an increase in the Arab population was noticed (7.7-10.2 and 3.7-4.2 cases per 100,000 in men and women, respectively). Age-adjusted mortality rates per 10,000 cases of gastric cancer decreased significantly, from 7.21 in 1990 to 5.46 in 2007, in the total population. The 5-year relative survival showed a slight increase for both men and women. There is a difference in the incidence and outcome of gastric cancer between the Jewish and Arab populations in Israel. The grim prognosis of gastric cancer patients in Israel is probably due to the advanced stage at which gastric cancer is diagnosed in Israel.

    To describe the incidence and histologic patterns of eye cancers in Chinese in Taiwan. Beginning in 1979, cases of cancer in Taiwan were reported to the Taiwan National Cancer Registry. Information on all Chinese patients diagnosed with eye malignancies under the International Classification of Disease, Ninth Revision, site 190, was retrieved for analysis from the data bank of the Taiwan National Cancer Registry. In all, 733 cases with primary eye cancers were identified from 1979 to 1996, an 18-year period. The average annual age-standardized incidence of eye cancers was 2.46 per million population (2.57 for male and 2.33 for female). For cases less than 15 years of age, the most common eye malignancy was retinoblastoma (86.0%), followed by rhabdomyosarcoma (3.9%) and lymphoma (2.8%). For cases 15 years of age or older, the most common eye malignancy was melanoma (28.6%), followed by squamous cell sarcoma (21.0%) and lymphoma (20.8%). The time trends of the incidence of eye cancers were relatively stable over the 18-year period in Taiwan. Retinobalstoma, melanoma, and lymphoma were the three most common eye cancers in this Chinese population.

    Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age. We used a nationwide population-based retrospective cohort study to explore the relationship between PCOS and the subsequent development of gynecological cancers including uterine, breast, or ovarian cancer. We identified subjects who were diagnosed with PCOS between January 1, 2000, and December 31, 2004, in the Taiwan National Health Insurance (NHI) Research Database. A comparison cohort was constructed for patients without known PCOS who were also matched according to age. All PCOS and control patients were observed until diagnosed with breast cancer, ovarian cancer, or uterine cancer or until death, withdrawal from the NHI system, or December 31, 2009. The PCOS cohort consisted of 3,566 patients, and the comparison cohort consisted of 14,264 matched control patients without PCOS. The adjusted hazard ratio (HR) of uterine cancer and breast cancer in subjects with PCOS were higher (HR: 8.42 [95% confidence interval: 1.62-43.89] and HR: 1.99 [95% confidence interval: 1.05-3.77], respectively) than that of the controls during the follow-up. With the Monte Carlo method, only the mean adjusted HR of 1,000 comparisons for developing uterine cancer during the follow-up period was greater for the PCOS group than for the control groups (HR: 4.71, 95% confidence interval: 1.57-14.11). PCOS might increase the risk of subsequent newly diagnosed uterine cancer. It is critical that further large-scale, well-designed studies be conducted to confirm the association between PCOS and gynecological cancer risk. ©AlphaMed Press.

    Higher coffee consumption has been associated with decreased incidence of colorectal cancer. Our objective was to examine the relationship of coffee intake to colorectal cancer incidence in a large observational cohort of postmenopausal US women. Methods. Data were collected for the Women’s Health Initiative Observational Study providing a follow-up period of 12.9 years. The mean age of our sample ( N = 83,778 women) was 63.5 years. Daily coffee intake was grouped into 3 categories: None, moderate (>0-<4 cups), and high (4+ cups). Proportional hazards modeling was used to evaluate the relationship between coffee intake and colorectal cancer. Results. There were 1,282 (1.53%) new cases of colorectal cancer during follow-up. Compared to nondrinkers, moderate and high coffee drinkers had an increased incidence of colorectal cancer in multivariate analysis (HR 1.15, 1.02-1.29; HR 1.14, 0.93-1.38). Moderate drip brew coffee intake (HR 1.20, 1.05-1.36) and high non drip brew coffee intake (HR 1.43, 1.01-2.02) were associated with increased odds. Conclusion. Our results suggesting increased incidence of colorectal cancer associated with higher coffee consumption contradict recent meta-analyses but agree with a number of other studies showing that coffee increases risk or has no effect. Brew method results are novel and warrant further research.

    Full Text Available To estimate the contribution of tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake to esophageal cancer mortality and incidence in China.We calculated the proportion of esophageal cancer attributable to four known modifiable risk factors [population attributable fraction (PAF]. Exposure data was taken from meta-analyses and large-scale national surveys of representative samples of the Chinese population. Data on relative risks were also from meta-analyses and large-scale prospective studies. Esophageal cancer mortality and incidence came from the 3(rd national death cause survey and population-based cancer registries in China. We estimated that 87,065 esophageal cancer deaths (men 67,686; women: 19,379 and 108,206 cases (men: 83,968, women: 24,238 were attributable to tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake in China in 2005. About 17.9% of esophageal cancer deaths among men and 1.9% among women were attributable to tobacco smoking. About 15.2% of esophageal cancer deaths in men and 1.3% in women were caused by alcohol drinking. Low vegetable intake was responsible for 4.3% esophageal cancer deaths in men and 4.1% in women. The fraction of esophageal cancer deaths attributable to low fruit intake was 27.1% in men and 28.0% in women. Overall, 46% of esophageal cancers (51% in men and 33% in women were attributable to these four modifiable risk factors.Tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake were responsible for 46% of esophageal cancer mortality and incidence in China in 2005. These findings provide useful data for developing guidelines for esophageal cancer prevention and control in China.

    The expression of A, B, and H group antigens, Lewis group antigens (Lewis(a), Lewis(b), Lewis(x), and Lewis(y)), and Lc4 and nLc4 antigens, the precursor antigens of both groups, was examined immunohistochemically with monoclonal antibodies in 9 normal endometria, 6 endometrial hyperplasias, and 31 endometrial cancers. 1) A, B and/or H antigens were detected in endometrial cancers at an incidence of 51.6%, while no distinct localization of these antigens was observed in normal endometria. H antigen, the precursor of A and B antigens, was particularly frequently detected in endometrial cancers. 2) An increased rate of expression of Lewis group antigens, particularly Lewis(b) antigen, was observed in endometrial cancers compared with its expression in normal endometria. 3) Lc4 and nLc4 antigens were detected in endometrial cancers at rates of 41.9% and 38.7%, respectively, these expressions being increased compared with those in normal endometria. 4) These results suggest that a highly abnormal expression of blood group-related antigens in endometrial cancers occurs not only at the level of A, B, and H antigens and Lewis group antigens, but also at the level of their precursor Lc4 and nLc4 antigens. 5) Lewis(a), Lewis(b), and Lc4 antigens, built on the type-1 chain, are more specific to endometrial cancers than their respective positional isomers, Lewis(x), Lewis(y), and nLc4 antigens, built on the type-2 chain.

    Previous analyses indicated that New Mexican Hispanics and American Indians (AI) did not experience the declining colorectal cancer (CRC) incidence and mortality rates observed among non-Hispanic whites (NHW). We evaluated more recent data to determine whether racial/ethnic differences persisted. Methods. We used New Mexico Surveillance Epidemiology and End Results data from 1995 to 2009 to calculate age-specific incidence rates and age-adjusted incidence rates overall and by tumor stage. We calculated mortality rates using National Center for Health Statistics’ data. We used join point regression to determine annual percentage change (APC) in age-adjusted incidence rates. Analyses were stratified by race/ethnicity and gender. Results. Incidence rates continued declining in NHW (APC −1.45% men, −1.06% women), while non significantly increasing for AI (1.67% men, 1.26% women) and Hispanic women (0.24%). The APC initially increased in Hispanic men through 2001 (3.33%, P = 0.06), before declining (−3.10%, P = 0,003). Incidence rates declined in NHW and Hispanics aged 75 and older. Incidence rates for distant-stage cancer remained stable for all groups. Mortality rates declined significantly in NHW and Hispanics. Conclusions. Racial/ethnic disparities in CRC persist in New Mexico. Incidence differences could be related to risk factors or access to screening; mortality differences could be due to patterns of care for screening or treatment.

    The retrospective cohort study of 'Cancer incidence among persons, working at ionizing radiation environment' was performed. The cohort consisted of 2034 persons (13.82% males and 86.18% females). Among them 475 were radiologists (doctors), 868 - radiologic technologists (all of them females) and 470 nurses (cleaners in radiology departments). The members of the cohort were followed -up retrospectively from 01.01.1978 until 31.12.1977. Standard Incidence Ratio for all cancers in the cohort of female radiologic technologists was 1,31 [0,90-1,85], of female nurses -1,99 [1,26-2,99]. The size of cohorts and follow-up period were too small for site - specific analysis of cancer incidence. (author)

    The thyroid cancer incidence in the Ukraine among those born in the period 1968-1986 was analyzed with the aim to identify the enhancement due to the Chernobyl accident. Since any Ukrainian data referring to the time period before the accident are scarce and the variation of spontaneous incidences in other countries is immense, the Ukrainian incidences in the period 1986-1989 were used to estimate the baseline risk. Following 1990, the incidence in the southern part of the Ukraine increased by about 30%, independent of age. In the other parts the increase of the incidence depended on age at exposure. In the age group of 9-year-old children, the incidences in three regions defined as the 'high-dose area', the northern, and the middle oblasts, increased by factors of 50, 20, and 6, respectively. These rates (1991-1995) are well above spontaneous rates in other countries. In the age group of 17-year-old juveniles, the incidence increased by a factor of 6 for the 'high dose area' and in the three northern oblasts, whereas in the nine 'middle' oblasts it was similar to the incidence of the 'southern' Ukraine. These rates are within the range found in other countries. (orig.)

    Fatherhood status has been hypothesized to affect prostate cancer risk but the current evidence is limited and contradictory. We prospectively evaluated the relationship between offspring number and the risk of prostate cancer in 161,823 men enrolled in the National Institues of Health - American Association of Retired Persons Diet and Health Study. Participants were aged 50-71 years without a cancer diagnosis at baseline in 1995. Analysing 8134 cases of prostate cancer, Cox regression was used to estimate the association between offspring number and prostate cancer incidence while accounting for socio-demographic and lifestyle characteristics. When examining the entire cohort, there was no relationship between fatherhood and incident prostate cancer [hazard ratio (HR) 0.94, 95% confidence interval (CI) 0.86-1.02]. However, after stratifying for prostate cancer screening, prostate-specific antigen (PSA) unscreened childless men had a lower risk of prostate cancer (HR 0.73, 95% CI 0.58-0.91) compared with fathers due to the interaction between PSA screening and fatherhood (P for interaction fatherhood status and offspring gender is associated with a man's prostate cancer risk.

  10. Age-specific incidence of all neoplasms after colorectal cancer.

    Patients diagnosed with a specific neoplasm tend to have a subsequent excess risk of the same neoplasm. The age incidence of a second neoplasm at the same site is approximately constant with age, and consequently the relative risk is greater at younger age. It is unclear whether such a line of reasoning can be extended from a specific neoplasm to the incidence of all neoplasms in subjects diagnosed with a defined neoplasm. We considered the age-specific incidence of all non-hormone-related epithelial neoplasms after a first primary colorectal cancer (n = 9542) in the Vaud Cancer Registry data set. In subjects with a previous colorectal cancer, the incidence rate of all other epithelial non-hormone-related cancers was stable around 800 per 100,000 between age 30 and 60 years, and rose only about twofold to reach 1685 at age 70 to 79 years and 1826 per 100,000 at age 80 years or older. After excluding synchronous cancers, the rise was only about 1.5-fold, that is, from about 700 to 1000. In the general population, the incidence rate of all epithelial non-hormone-related cancers was 29 per 100,000 at age 30 to 39 years, and rose 30-fold to 883 per 100,000 at age 70 to 79 years. Excluding colorectal cancers, the rise of all non-hormone-related cancers was from 360 per 100,000 at age 40 to 49 years to 940 at age 70 to 79 years after colorectal cancer, and from 90 to 636 per 100,000 in the general population (i.e., 2.6- vs. 7.1-fold). The rise of incidence with age of all epithelial non-hormone-related second cancers after colorectal cancer is much smaller than in the general population. This can possibly be related to the occurrence of a single mutational event in a population of susceptible individuals, although alternative models are plausible within the complexity of the process of carcinogenesis.

    A prior analysis of patients undergoing laparotomy for ovarian malignancies at our institution revealed an increased rate of intra-abdominal collections using HA-CMC film during debulking surgery. The primary objective of the current study was to determine whether the use of HA-CMC is associated with the development of postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical malignancies. We retrospectively identified all laparotomies performed for these malignancies from 3/1/05 to 12/31/07. We identified cases involving the use of HA-CMC via billing records and operative reports. Intra-abdominal collections were defined as localized intraperitoneal fluid accumulations in the absence of re-accumulating ascites. We noted incidences of intra-abdominal collections, as well as other complications. Appropriate statistical tests were applied using SPSS 15.0. We identified 169 laparotomies in which HA-CMC was used and 347 in which HA-CMC was not used. The following were statistically similar in both cohorts: age, body mass index (BMI), primary site, surgery for recurrent disease, prior intraperitoneal surgery, and extent of current surgery. Intra-abdominal collections were seen in 6 (3.6%) of 169 HA-CMC cases compared to 10 (2.9%) of 347 non-HA-CMC cases (p=0.7). The rate of infected collections was similar in both groups (1.2% vs. 1.4%). In the subgroup that underwent tumor debulking, intra-abdominal collections were seen in 3 (11.5%) of 26 HA-CMC cases compared to 2 (5.4%) of 37 non-HA-CMC cases (p=0.6). HA-CMC use does not appear to be associated with postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical cancer. Copyright © 2010 Elsevier Inc.

    Among a total of 65,268 Nagasaki atomic bomb survivors recorded in the Scientific Data Center of Atomic Bomb Disaster, Nagasaki University School of Medicine, 140 cases with skin cancer were collected from 31 hospitals in Nagasaki City from 1961 through 1987. Subsequently, these cases of skin cancer in Nagasaki atomic bomb survivors were statistically analyzed in relation to the estimated distance from the hypocenter by age, sex, histology and latent period. The results were as follows: (1) A high correlation was observed between the incidence of skin cancer and the distance from the hypocenter. (2) The incidence of skin cancer in Nagasaki atomic bomb survivors now appears to be increasing in relation to exposure distance. (3) Among 140 cases, basal cell epithelioma was observed in 67 cases (47.9%) and squamous cell carcinoma in 43 cases (30.7%). (author)

    This study aimed to determine surgical outcomes related to hand-assisted robotic surgery (HARS) for staging of ovarian cancer and uterine cancers with high risk of peritoneal spread and compare them to laparotomy and standard robotic-assisted surgery. A retrospective cohort study of women undergoing staging for uterine and ovarian cancer between January 2011 and July 2013 at a major metropolitan teaching hospital was reviewed. Patients undergoing HARS were matched with patients undergoing staging laparotomy [exploratory laparotomy (XLAP)] for the same indications and with patients undergoing traditional robotic surgery (RS) for staging of endometrioid endometrial cancer. In HARS, a longer incision is used to allow palpation of the peritoneal surfaces, to exteriorize the small bowel, to examine the mesentery, and to perform omentectomy. One hundred five patients were analyzed (15 HARS, 45 RS, 45 XLAP). Compared with XLAP, HARS was associated with decreased blood loss (200 vs 400 mL, P = 0.011) and shorter hospital stay (1 vs 4 days, P < 0.001). Patients who had undergone HARS had fewer major complications, but those results did not reach statistical significance (0% vs 27%, P = 0.063). Hand-assisted robotic surgery was associated with higher blood loss and length of stay as compared to robotic staging of endometrioid endometrial cancer (RS). Minor wound complications were also more common (27% vs 2%, P = 0.012). Hand-assisted robotic surgery allows for thorough visual and tactile assessment of peritoneal surfaces. It represents a safe alternative to laparotomy for staging of ovarian and uterine cancers with high risk of peritoneal spread. Long-term follow-up study is needed to determine oncologic adequacy of HARS.

    Uterine cervix cancer is one of the most prevalent women cancer in Korea. We analysed published papers in Korea with comparing Patterns of Care Study (PCS) articles of United States and Japan for the purpose of developing and processing Korean PCS. We searched PCS related foreign-produced papers in the PCS homepage (212 articles and abstracts) and from the Pub Med to find Structure and Process of the PCS. To compare their study with Korean papers, we used the internet site 'Korean Pub Med' to search 99 articles regarding uterine cervix cancer and radiation therapy. We analysed Korean paper by comparing them with selected PCS papers regarding Structure, Process and Outcome and compared their items between the period of before 1980's and 1990's. Evaluable papers were 28 from United States, 10 from the Japan and 73 from the Korea which treated cervix PCS items. PCS papers for United States and Japan commonly stratified into 3 ∼ 4 categories on the bases of the scales characteristics of the facilities, numbers of the patients, doctors. Researchers restricted eligible patients strictly. For the process of the study, they analysed factors regarding pretreatment staging in chronological order, treatment related factors, factors in addition to FIGO staging and treatment machine. Papers in United States dealt with racial characteristics, socioeconomic characteristics of the patients, tumor size (6), and bilaterality of parametrial or pelvic side wall invasion (5), whereas papers from Japan treated of the tumor markers. The common trend in the process of staging work-up was decreased use of lymphangiogram, barium enema and increased use of CT and MRI over the times. The recent subject from the Korean papers dealt with concurrent chemoradiotherapy (9 papers), treatment duration (4), tumor markers (8) and unconventional fractionation. By comparing papers among 3 nations, we collected items for Korean uterine cervix cancer PCS. By consensus meeting and close communication

    Knowledge of a country's cervical cancer (CC) burden is critical to informing decisions about resource allocation to combat the disease; however, many countries lack cancer registries to provide such data. We developed a prognostic model to estimate CC incidence rates in countries without cancer registries, leveraging information on human papilloma virus (HPV) prevalence, screening, and other country-level factors. We used multivariate linear regression models to identify predictors of CC incidence in 40 countries. We extracted age-specific HPV prevalence (10-year age groups) by country from a meta-analysis in women with normal cytology (N = 40) and matched to most recent CC incidence rates from Cancer Incidence in Five Continents when available (N = 36), or Globocan 2008 (N = 4). We evaluated country-level behavioral, economic, and public health indicators. CC incidence was significantly associated with age-specific HPV prevalence in women aged 35-64 (adjusted R-squared 0.41) ("base model"). Adding geographic region to the base model increased the adjusted R-squared to 0.77, but the further addition of screening was not statistically significant. Similarly, country-level macro-indicators did not improve predictive validity. Age-specific HPV prevalence at older ages was found to be a better predictor of CC incidence than prevalence in women under 35. However, HPV prevalence could not explain the entire CC burden as many factors modify women's risk of progression to cancer. Geographic region seemed to serve as a proxy for these country-level indicators. Our analysis supports the assertion that conducting a population-based HPV survey targeting women over age 35 can be valuable in approximating the CC risk in a given country. Copyright © 2012 UICC.

    Full Text Available Air pollution exposure has been shown to be associated with an increased risk of specific cancers. This study investigated whether the number and incidence of the most common cancers in Saudi Arabia were associated with urban air pollution exposure, specifically NO2. Overall, high model goodness of fit (GOF was observed in the Eastern, Riyadh and Makkah regions. The significant coefficients of determination (r2 were higher at the regional level (r2 = 0.32–0.71, weaker at the governorate level (r2 = 0.03–0.43, and declined slightly at the city level (r2 = 0.17–0.33, suggesting that an increased aggregated spatial level increased the explained variability and the model GOF. However, the low GOF at the lowest spatial level suggests that additional variation remains unexplained. At different spatial levels, associations between NO2 concentration and the most common cancers were marginally improved in geographically weighted regression (GWR analysis, which explained both global and local heterogeneity and variations in cancer incidence. High coefficients of determination were observed between NO2 concentration and lung and breast cancer incidences, followed by prostate, bladder, cervical and ovarian cancers, confirming results from other studies. These results could be improved using individual explanatory variables such as environmental, demographic, behavioral, socio-economic, and genetic risk factors.

    Colorectal cancer incidence in the Life Span Study (LSS) sample during 1950-80 was investigated. A total of 730 incidence cases of colorectal cancer were confirmed from a variety of sources. Sixty-two percent of the cancers were microscopically verified and 12% were ascertained through death certificate only. The risk of colon cancer increased significantly with intestinal dose, but no definite increase of risk was observed for rectal cancer. Relative risk at 1 Sv and excess risk per 10 4 PY-Sv for colon cancer are 1.80 (90% confidence interval 1.37-2.36) and 0.36 (90% confidence interval 0.06-0.77) respectively. City and sex did not significantly modify the dose-response of colon cancer, but the risk decreased with age at the time of bombings (ATB). The relative risk of colon cancer does not vary substantially over time following exposure. A non-linear dose response did not significantly improve the fit. Further, the anatomic location of the tumors indicate that the cecum and ascending, transverse and descending, and sigmoid colon seem equally sensitive to radiation. No difference in the distribution of tumor histological types could be observed by radiation dose. (author)

    Different ethnicities have different distribution of Duffy blood group (DBG) phenotypes and different breast cancer morbidity. A study in our lab demonstrated that Duffy antigen/receptor for chemokines (DARC, also known as DBGP, the Duffy protein phenotype), led to the inhibition of tumorigenesis. Therefore, we tested the hypothesis that DBGP is correlated with breast cancer occurrence. DBGP proteins were examined by indirect antiglobulin testing with anti-FYa and anti-FYb antibodies. The phenotypes were classified into four groups according to the agglutination reactions: FYa + FYb+, FYa + FYb-, FYa-FYb + and FYa-FYb-. The phenotypes and pathological diagnosis of consecutively hospitalized female patients (n = 5,022) suffering from breast cancer at the Shanghai Cancer Hospital and Henan Province Cancer Hospital were investigated. The relationships between DBGP expression with breast cancer occurrence, axillary lymph status, histological subtype, tumor size pathological grade and overall survival were analyzed. The incidence of breast cancer was significantly different between FYa + FYb + (29.8%), FYa + FYb- (33.2%), FYa-FYb + (45.6%) and FYa-FYb- (59.1%; P = 0.001). Significant different numbers of breast cancer patients had metastases to the axillary lymph nodes in the FYa + FYb + group (25.1%), FYa + FYb- (36.9%), FYa-FYb + (41.0%) and FYa-FYb- (50.0%, (P = 0.005). There was a statistical significance (p = 0.022) of the overall survival difference between patients with difference phenotypes. No significant difference was observed in cancer size (t-test, p > 0.05), histological cancer type (Fisher's exact test, p > 0.05) or histological grade (Fisher's exact test, p > 0.05) between every each DBGP group. DBGP is correlated with breast cancer incidence and axillary lymph node metastasis and overall survival. Further investigations are required to determine the underlying mechanism of Duffy blood group phenotype on breast cancer risk

    Nonmelanoma skin cancer (NMSC) is the most common cancer among Caucasian populations worldwide, and incidence rates are increasing. However, NMSC data are not routinely collected by cancer registries, but Denmark has extensive registration of NMSC in two nationwide population-based registries. We...... assessed incidence trends of NMSC in Denmark from 1978 to 2007. Data for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) were obtained from the Danish Cancer Registry and the Danish Registry of Pathology. For both genders, age-specific incidence rates and overall incidence rates, age...

    Full Text Available Endometrial cancer is the most common gynecologic malignancy, and its incidence and associated mortality are increasing. Despite the immediate need to detect these cancers at an earlier stage, there is no effective screening methodology or protocol for endometrial cancer. The comprehensive, genomics-based analysis of endometrial cancer by The Cancer Genome Atlas (TCGA revealed many of the molecular defects that define this cancer. Based on these cancer genome results, and in a prospective study, we hypothesized that the use of ultra-deep, targeted gene sequencing could detect somatic mutations in uterine lavage fluid obtained from women undergoing hysteroscopy as a means of molecular screening and diagnosis.Uterine lavage and paired blood samples were collected and analyzed from 107 consecutive patients who were undergoing hysteroscopy and curettage for diagnostic evaluation from this single-institution study. The lavage fluid was separated into cellular and acellular fractions by centrifugation. Cellular and cell-free DNA (cfDNA were isolated from each lavage. Two targeted next-generation sequencing (NGS gene panels, one composed of 56 genes and the other of 12 genes, were used for ultra-deep sequencing. To rule out potential NGS-based errors, orthogonal mutation validation was performed using digital PCR and Sanger sequencing. Seven patients were diagnosed with endometrial cancer based on classic histopathologic analysis. Six of these patients had stage IA cancer, and one of these cancers was only detectable as a microscopic focus within a polyp. All seven patients were found to have significant cancer-associated gene mutations in both cell pellet and cfDNA fractions. In the four patients in whom adequate tumor sample was available, all tumor mutations above a specific allele fraction were present in the uterine lavage DNA samples. Mutations originally only detected in lavage fluid fractions were later confirmed to be present in tumor but at

    Objective: To evaluate an alternative brachytherapy technique for uterine cervix cancer involving the distal vagina, without increasing the risk of toxicity. Materials And Methods: Theoretical study comparing three different high-dose rate intracavitary brachytherapy applicators: intrauterine tandem and vaginal cylinder (TC); tandem/ring applicator combined with vaginal cylinder (TR+C); and a virtual applicator combining both the tandem/ring and vaginal cylinder in a single device (TRC). Prescribed doses were 7 Gy at point A, and 5 Gy on the surface or at a 5 mm depth of the vaginal mucosa. Doses delivered to the rectum, bladder and sigmoid colon were kept below the tolerance limits. Volumes covered by the isodoses, respectively, 50% (V50), 100% (V100), 150% (V150) and 200% (V200) were compared. Results: Both the combined TR+C and TRC presented a better dose distribution as compared with the TC applicator. The TR+C dose distribution was similar to the TRC dose, with V150 and V200 being about 50% higher for TR+C (within the cylinder). Conclusion: Combined TR+C in a two-time single application may represent an alternative therapy technique for patients affected by uterine cervix cancer involving the distal vagina. (author)

    Objective. Use of cancer cases from registries and PMSI claims database to estimate Department-specific incidence of four major cancers. Methods. Case extraction used principal diagnosis then surgery codes. PMSI cases/registry cases ratios for 2004 were modelled then Department-specific incidence for 2007 estimated using these ratios and 2007 PMSI cases. Results. For 2007, only colon-rectum and breast cancer estimations were satisfactorily validated for infra national incidence not ovary and kidney cancers. For breast, the estimated national incidence was 50,578 cases and the incidence rate 98.6 cases per 100,000 person per year. For colon-rectum, incidence was 21,172 in men versus 18,327 in women and the incidence rate 38 per 100,000 versus 24.8. For ovary, the estimated incidence was 4,637 and the rate 8.6 per 100,000. For kidney, incidence was 6,775 in men versus 3,273 in women and the rate 13.3 per 100.000 versus 5.2. Conclusion. Incidence estimation using PMSI patient identifiers proved encouraging though still dependent on the assumption of uniform cancer treatments and coding.

    Purpose : Despite a development for therapeutic machines and advance in modern radiation therapy techniques, locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate. Combination of chemotherapy and radiotherapy demonstrated benefit in improving local control and possibly the overall survival. Our study was performed to evaluate effect of concurrent chemoradiation on locally advanced uterine cervical cancer. Methods and Materials : Twenty six patients with locally advanced stage(FIGO stage IIB with ≥ 5 cm in diameter, III, IVA) were treated with combination of radiation therapy and concurrent cisplatinum between May of 1988 and September of 1993 at our hospital. Radiation therapy consisted of external irradiation and 1-2 sessions of intracavitary irradiation, Cisplatinum was administered in bolus injection of 25mg/m 2 at weekly intervals during the course of external radiation therapy. Results : Of the 26 patients, twenty-five patients were evaluable for estimation of response. Median follow-up period was 25 months with ranges from 3 to 73 months. Stage IIB, III, and IVA were 16, 5,4 patients, respectively. Twenty patients were squamous cell carcinoma. Response was noted in all 25 patients: complete response(CR) in 17/25(68%), partial response(PR) in 8/25(32%). Of the 24 patients except one who died of sepsis at 3 months follow-up, seventeen patients(70.8%) maintained local control in the pelvis: 16/17(94.1%) in CR, 1/17(14.3%) in PR. Fourteen of the 17 patients with CR are alive disease free on the completion of follow-up. Median survival is 28 months for CR and 15 months for PR.

    Treatment outcomes of patients with pelvic recurrence after hysterectomy alone for uterine cervical cancer who received salvage radiotherapy (RT) with or without concurrent chemotherapy were investigated. Salvage RT for recurrent cervical cancer confined to the pelvic cavity after hysterectomy alone was received by 33 patients. The median interval between initial hysterectomy and recurrence was 26 months. Whole-pelvic irradiation was delivered to median dose of 45 Gy, followed by a boost with a median dose of 16 Gy to the gross tumor volume. Cisplatin-based concurrent chemotherapy was administered to 29 patients. The median follow-up period was 53 months for surviving patients. Most patients (97.0%) completed salvage RT of ≥45 Gy. Complete response (CR) was achieved in 23 patients (69.7%). Pelvic sidewall involvement and evaluation with positron-emission tomography-computed tomography were significantly associated with CR. The 5-year progression-free survival (PFS), local control (LC), distant metastasis-free survival (DMFS), and overall survival (OS) rates were 62.7, 79.5, 72.5, and 60.1%, respectively. Initial International Federation of Gynecology and Obstetrics stage, pelvic sidewall involvement, and CR status were significant factors for PFS and OS rates in multivariate analysis. The incidence of severe acute and late toxicities (≥grade 3) was 12.1 and 3.0%, respectively. Aggressive salvage RT with or without concurrent chemotherapy for recurrent cervical cancer confined to the pelvic cavity was feasible, with promising treatment outcomes and acceptable toxicities. However, even more intensive novel treatment strategies should be investigated for patients with unfavorable prognostic factors. (orig.)

  9. Phenomenological modelling of second cancer incidence for radiation treatment planning

    2009-01-01

    It is still an unanswered question whether a relatively low dose of radiation to a large volume or a higher dose to a small volume produces the higher cancer incidence. This is of interest in view of modalities like IMRT or rotation therapy where high conformity to the target volume is achieved at the cost of a large volume of normal tissue exposed to radiation. Knowledge of the shape of the dose response for radiation-induced cancer is essential to answer the question of what risk of second cancer incidence is implied by which treatment modality. This study therefore models the dose response for radiation-induced second cancer after radiation therapy of which the exact mechanisms are still unknown. A second cancer risk estimation tool for treatment planning is presented which has the potential to be used for comparison of different treatment modalities, and risk is estimated on a voxel basis for different organs in two case studies. The presented phenomenological model summarises the impact of microscopic biological processes into effective parameters of mutation and cell sterilisation. In contrast to other models, the effective radiosensitivities of mutated and non-mutated cells are allowed to differ. Based on the number of mutated cells present after irradiation, the model is then linked to macroscopic incidence by summarising model parameters and modifying factors into natural cancer incidence and the dose response in the lower-dose region. It was found that all principal dose-response functions discussed in the literature can be derived from the model. However, from the investigation and due to scarcity of adequate data, rather vague statements about likelihood of dose-response functions can be made than a definite decision for one response. Based on the predicted model parameters, the linear response can probably be rejected using the dynamics described, but both a flattening response and a decrease appear likely, depending strongly on the effective cell

  10. An assessment of interfractional uterine and cervical motion: Implications for radiotherapy target volume definition in gynaecological cancer

    2008-01-01

    Purpose: To assess interfractional movement of the uterus and cervix in patients with gynaecological cancer to aid selection of the internal margin for radiotherapy target volumes. Methods and materials: Thirty-three patients with gynaecological cancer had an MRI scan performed on two consecutive days. The two sets of T2-weighted axial images were co-registered, and the uterus and cervix outlined on each scan. Points were identified on the anterior uterine body (Point U), posterior cervix (Point C) and upper vagina (Point V). The displacement of each point in the antero-posterior (AP), supero-inferior (SI) and lateral directions between the two scans was measured. The changes in point position and uterine body angle were correlated with bladder volume and rectal diameter. Results: The mean difference (±1SD) in Point U position was 7 mm (±9.0) in the AP direction, 7.1 mm (±6.8) SI and 0.8 mm (±1.3) laterally. Mean Point C displacement was 4.1 mm (±4.4) SI, 2.7 mm (±2.8) AP, 0.3 (±0.8) laterally, and Point V was 2.6 mm (±3.0) AP and 0.3 mm (±1.0) laterally. There was correlation for uterine SI movement in relation to bladder filling, and for cervical and vaginal AP movement in relation to rectal filling. Conclusion: Large movements of the uterus can occur, particularly in the superior-inferior and anterior-posterior directions, but cervical displacement is less marked. Rectal filling may affect cervical position, while bladder filling has more impact on uterine body position, highlighting the need for specific instructions on bladder and rectal filling for treatment. We propose an asymmetrical margin with CTV-PTV expansion of the uterus, cervix and upper vagina of 15 mm AP, 15 mm SI and 7 mm laterally and expansion of the nodal regions and parametria by 7 mm in all directions

    Lung cancer is the most common cancer worldwide, but epidemiologic data from developing countries are lacking. This article reports lung cancer incidence and survival in Rabat, the capital of Morocco. All lung cancer cases diagnosed between 2005 and 2008 were analyzed using data provided by the Rabat Cancer Registry. The standardized rate was reported using age adjustment with respect to the world standard population, and the observed survival rates were calculated using the Kaplan-Meier method. Three hundred fifty-one cases were registered (314 males and 37 females), aged 27-90 years (median, 59 years). The most common pathological type was adenocarcinoma (40.2%) followed by squamous cell carcinoma (31.9%); the majority of cases were diagnosed at stage IV (52%). The age-standardized incidence rate was 25.1 and 2.7 per 100,000 for males and females, respectively, and the overall observed survival rates at 1 and 5 years were 31.7% and 3.4%, respectively. The clinical stage of disease was the only independent predictor of survival. The survival rate of lung cancer in Rabat is very poor. This finding explains the need for measures to reduce the prevalence of tobacco and to improve diagnostic and therapeutic facilities for lung cancer. Copyright © 2016.

    Full Text Available Predicting high risk groups for gastric cancer and motivating these groups to receive regular checkups is required for the early detection of gastric cancer. The aim of this study is was to develop a prediction model for gastric cancer incidence based on a large population-based cohort in Korea.Based on the National Health Insurance Corporation data, we analyzed 10 major risk factors for gastric cancer. The Cox proportional hazards model was used to develop gender specific prediction models for gastric cancer development, and the performance of the developed model in terms of discrimination and calibration was also validated using an independent cohort. Discrimination ability was evaluated using Harrell's C-statistics, and the calibration was evaluated using a calibration plot and slope.During a median of 11.4 years of follow-up, 19,465 (1.4% and 5,579 (0.7% newly developed gastric cancer cases were observed among 1,372,424 men and 804,077 women, respectively. The prediction models included age, BMI, family history, meal regularity, salt preference, alcohol consumption, smoking and physical activity for men, and age, BMI, family history, salt preference, alcohol consumption, and smoking for women. This prediction model showed good accuracy and predictability in both the developing and validation cohorts (C-statistics: 0.764 for men, 0.706 for women.In this study, a prediction model for gastric cancer incidence was developed that displayed a good performance.

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    2008-09-01

    Full Text Available Abstract Background Fanconi anemia (FA is an autosomal recessive DNA repair disorder with affected individuals having a high risk of developing acute myeloid leukaemia and certain solid tumours. Thirteen complementation groups have been identified and the genes for all of these are known (FANCA, B, C, D1/BRCA2, D2, E, F, G, I, J/BRIP1, L, M and N/PALB2. Previous studies of cancer incidence in relatives of Fanconi anemia cases have produced conflicting results. A study of British FA families was therefore carried out to investigate this question, since increases in cancer risk in FA heterozygotes would have implications for counselling FA family members, and possibly also for the implementation of preventative screening measures in FA heterozygotes. Methods Thirty-six families took part and data was collected on 575 individuals (276 males, 299 females, representing 18,136 person years. In this cohort, 25 males and 30 females were reported with cancer under the age of 85 years, and 36 cancers (65% could be confirmed from death certificates, cancer registries or clinical records. Results A total of 55 cancers were reported in the FA families compared to an estimated incidence of 56.95 in a comparable general population cohort, and the relative risk of cancer was 0.97 (95% C.I. = 0.71–1.23, p = 0.62 for FA family members. Analysis of relative risk for individual cancer types in each carrier probability group did not reveal any significant differences with the possible exception of prostate cancer (RR = 3.089 (95% C.I. = 1.09 – 8.78; Χ2 = 4.767, p = 0.029. Conclusion This study has not shown a significant difference in overall cancer risk in FA families.

    The need for radiotherapy (RT) in cancer treatment for the elderly patient is growing. The purpose of this study was to analyze the efficacy and complication rate for radiotherapy, using external-beam irradiation (EBRT) and high dose-rate intracavitary brachytherapy (HDRICB), for patients aged 70 years or older with carcinoma of the uterine cervix. From September 1992 to December 1997, 295 patients diagnosed with uterine cervical cancer completed RT at the Shin Kong Memorial Hospital and China Medical College Hospital. Two hundred and fifty-eight patients [International Federation of Gynecology and Obstetrics (FIGO) stage distribution: 35 Ib, 26 IIa, 122 IIb, 10 IIIa, 58 IIIb, 7 IVa] who had undergone at least two courses of HDRICB and a minimum of 3 years of follow-up, were evaluated. A retrospective analysis was conducted to compare the outcome of radiation therapy for the 179 patients under 70 years of age (younger group) and the 79 patients aged 70 years or older (older group). The RT consisted of EBRT followed by HDRICB. After a total EBRT dose of 40-45 Gy/20 in 25 fractions, irradiating the whole pelvis over 4-5 weeks, dosage for patients diagnosed as FIGO stage IIb-IVa bilateral parametrial disease was boosted to 54-58 Gy, with central shielding. HDRICB was administered at 1-week intervals using an Ir-192 remote after-loading technique. Ninety-nine patients (38.4%) received three fractions of HDRICB, while 156 patients (60.5%) had four fractions. Total prescribed Point A dosages (EBRT+HDRICB) ranged from 58 to 71.6 Gy (median, 65.6 Gy) for stage IB-IIA, while for larger lesions (stage IIB-IVA) analogous dosages were 59-75.6 Gy (median, 65.6 Gy). Median follow-up durations for the older and younger groups were 56/55 months, respectively. The respective 5-year actuarial survivals (AS) for the older and younger groups were 82/85% for stage Ib, 65/65% for IIa, 61/71% for IIb and 35/59% for IIIa-b. The 5-year cause-specific survivals (CSS) for the older and

    Cervical disease burden continues to be especially high in HIV-infected women, even in the era of effective antiretroviral medications. This review discusses the multiple issues surrounding HIV-associated cervical cancer. Also, the unique treatment-related issues in HIV-associated cervical cancer are addressed. The incidence of invasive cervical cancer has remained stable in industrialized nations; however, it is only estimated in developing countries secondary to a relative lack of data collection and registries. Trends in HIV-associated cervical cancer have changed in the highly active antiretroviral therapy (HAART) era. Recent molecular pathways suggest that the natural progression of human papillomavirus infection, the causal agent in all cervical cancers, may be related to immune system dysfunction as well as HIV/human papillomavirus synergistic mechanisms. When highly active retroviral therapies are used, invasive cervical cancer treatments are impacted by concomitant drug toxicities that could potentially limit therapeutic benefit of either HAART or the standard of care treatment for locally advanced cervical cancer, concomitant chemoradiotherapy. The significance and care of the patient with invasive cervical cancer is becoming a geographically relevant phenomenon such that it may be time to re-address the global definition. Further studies in treatment issues and drug-drug interactions with cervical cancer treatments in the setting of HIV are paramount.

  20. Ozone depletion, related UVB changes and increased skin cancer incidence

    Science.gov (United States)

    Kane, R. P.

    1998-03-01

    Stratospheric ozone at middle latitudes shows a seasonal variation of about +/-20%, a quasi-biennial oscillation of 1-10% range and a long-term variation in which the level was almost steady up to about 1979 and declined thereafter to the present day by about 10%. These variations are expected to be reflected in solar UVB observed at the ground, but in an opposite direction. Thus UVB should have had a long-term increase of about 10-20%, which should cause an increase in skin cancer incidence of about 20-40%. Skin cancer incidence has increased all over the world, e.g. about 90% in USA during 1974-1990. It is popularly believed that this increase in skin cancer incidence is related to the recent ozone depletion. This seems to be incorrect, for two reasons. Firstly, the observed skin cancer increase is too large (90%) compared with the expected value (40%) from ozone depletion. Secondly, cancer does not develop immediately after exposure to solar UVB. The sunburns may occur within hours; but cancer development and detection may take years, even decades. Hence the observed skin cancer increase since 1974 (no data available for earlier periods) must have occurred due to exposure to solar UVB in the 1950s and 1960s, when there was no ozone depletion. Thus, the skin cancer increase must be attributed to harmful solar UVB levels existing even in the 1960s, accentuated later not by ozone depletion (which started only much later, by 1979) but by other causes, such as a longer human life span, better screening, increasing tendencies of sunbathing at beaches, etc., in affluent societies. On the other hand, the recent ozone depletion and the associated UVB increases will certainly take their toll; only that the effects will not be noticed now but years or decades from now. The concern for the future expressed in the Montreal Protocol for reducing ozone depletion by controlling CFC production is certainly justified, especially because increased UVB is harmful to animal and

    This report describes the formation of the National Cancer Incidence Reporting System in a data base format suitable for computerized record linkage, and the linkage of the data from the Canadian study of cancer following multiple fluoroscopies to that database and to the Canadian National Mortality Data Base between 1940 and 1987. A comprehensive statistical analysis of the breast cancer mortality data occurring among female members of the cohort between 1950 and 1987 with respect to exposure to low-LET radiation is reported, together with a parallel analysis of the breast cancer incidence data between 1975 and 1983. The Canadian fluoroscopy study is a cohort study of tuberculosis patients first treated in Canadian institutions between 1930 and 1952. The present mortality analysis relates to the breast cancer mortality experience between 1950 and 1987. A total of 677 deaths from breast cancer was observed in this period. The most appropriate dose-response relationship appears to be a simple linear one. There is a strong modifying influence of age at first exposure; women first exposed past the age of 30 have little excess risk due to radiation exposure. The breast cancer incidence analysis is based upon 628 cases observed between 1975 and 1983. Again a simple linear model appears to provide an adequate fit to the data. There is a suggestion of time dependency under the additive model, but this is not statistically significant. The results from this latest analysis continue to be reassuring in terms of radiation risk from mammography. (L.L.) 15 refs., figs., tabs

  2. Increasing incidence of testicular cancer--birth cohort effects.

    Ekbom, A; Akre, O

    1998-01-01

    The incidence of testicular cancer is rising in most Western populations. A collaborative study between nine population-based cancer registries in countries around the Baltic Sea was utilized in order to analyze in detail geographic variations and temporal trends in the occurrence of testicular cancer. There were 34,309 cases registered up until 1989 starting in Denmark in 1942 and most recently in Latvia in 1977. From the descriptive epidemiology it was obvious that there was a substantial variation in the age-standardized incidence amounting to about a 10-fold difference between the different countries ranging from 0.8 per 100,000 person-years in Lithuania to 7.6 per 100,000 person-years in Denmark. Previous studies have indicated that this increase is due to birth cohort effects. A more detailed analysis was therefore performed in those six countries with a sufficiently long period of cancer registration; Poland, former East Germany, Norway, Finland, Denmark and Sweden. This analysis showed that birth cohort is a more important determinant of testicular cancer risk than year of diagnosis. In Poland, former East Germany and Finland, there was an increasing risk for all birth cohorts. Among men born in Denmark, Norway or Sweden between 1930 and 1945, this increasing trend in risk was interrupted in these birth cohorts but followed thereafter by an uninterrupted increase by birth cohort. In conclusion, life time exposure to environmental factors which are associated with the incidence of testicular cancer appear to be more related to birth cohort than to year of diagnosis. Because testicular cancer typically occurs at an early age, major etiological factors therefore need to operate early in life, perhaps even in utero.

    Objective: In this study, the authors discussed the feasibility and value of diffusion-weighted (DW) MR imaging in the detection of uterine endometrial cancer in addition to conventional nonenhanced MR images. Methods and materials: DW images of endometrial cancer in 23 patients were examined by using a 1.5-T MR scanner. This study investigated whether or not DW images offer additional incremental value to conventional nonenhanced MR imaging in comparison with histopathological results. Moreover, the apparent diffusion coefficient (ADC) values were measured in the regions of interest within the endometrial cancer and compared with those of normal endometrium and myometrium in 31 volunteers, leiomyoma in 14 patients and adenomyosis in 10 patients. The Wilcoxon rank sum test was used, with a p -3 mm 2 /s, which was significantly lower than those of the normal endometrium, myometrium, leiomyoma and adenomyosis (p < 0.05). Conclusion: DW imaging can be helpful in the detection of uterine endometrial cancer in nonenhanced MR imaging.

Methods and materials: DW images of endometrial cancer in 23 patients were examined by using a 1.5-T MR scanner. This study investigated whether or not DW images offer additional incremental value to conventional nonenhanced MR imaging in comparison with histopathological results. Moreover, the apparent diffusion coefficient (ADC) values were measured in the regions of interest within the endometrial cancer and compared with those of normal endometrium and myometrium in 31 volunteers, leiomyoma in 14 patients and adenomyosis in 10 patients. The Wilcoxon rank sum test was used, with a p < 0.05 considered statistically significant. Results: In 19 of 23 patients, endometrial cancers were detected only on T2-weighted images. In the remaining 4 patients, of whom two had coexisting leiomyoma, no cancer was detected on T2-weighted images. This corresponds to an 83% detection sensitivity for the carcinomas. When DW images and fused DW images/T2-weighted images were used in addition to the T2-weighted images, cancers were identified in 3 of the remaining 4 patients in addition to the 19 patients (overall detection sensitivity of 96%). The mean ADC value of endometrial cancer (n = 22) was (0.97 {+-} 0.19) x 10{sup -3} mm{sup 2}/s, which was significantly lower than those of the normal endometrium, myometrium, leiomyoma and adenomyosis (p < 0.05). Conclusion: DW imaging can be helpful in the detection of uterine endometrial cancer in nonenhanced MR imaging.

    Objective Previous studies evaluating whether risk factors for gastric cancer are also associated with colorectal cancer (CRC) have shown inconsistent results. We prospectively examined the association of atrophic gastritis, a pre-malignant condition for gastric cancer and long-term sequelae common to many exposure factors, and the risk of incident CRC. Methods A total of 20,928 Finnish male smokers, aged 50–69, who were participants in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC) had serum pepsinogen I (SPGI) levels measured. Participants with low SPGI levels (gastritis was histologically confirmed in 1,006 (95.0%) participants. We used Cox proportional hazards regression to evaluate the risk of incident CRC. Results During a mean follow-up of 11.3 years (236,258 person-years), 425 incident CRC were diagnosed. The incidence rates were 1.82, 1.48, and 1.82 per 1,000 person-years of follow-up for participants with normal SPGI (≥25 µg/l), low SPGI, and histologically-confirmed atrophic gastritis, respectively. Compared to subjects with normal SPGI, there was no increased risk of CRC among subjects with low SPGI (Adjusted Hazard Ratio (HR) = 0.71; 95%CI: 0.47–1.05) and among those with histologically-confirmed atrophic gastritis (Adjusted HR = 0.86; 95%CI: 0.55–1.34). Conclusions Atrophic gastritis is not associated with an increased risk of colorectal cancer among male smokers. PMID:19838812

    There are few reports on uterine cancer in relation to radiation. This chapter discusses uterine cancer in A-bomb survivors, with special reference to the mortality rate, in a review of the literature. The Atomic Bomb Casualty Commission has first discovered 28 cases of uterine cancer among A-bomb survivors during the period 1953-1957. Since 1970, mortality rate from uterine cancer has been investigated statistically according to the T65D system. The Radiation Effect Research Foundation (RERF) has revealed 282 death cases from uterine cancer during the period 1950-1974. The RERF's data up to 1982 has revealed no radiation-dependent mortality from uterine cancer. More recent data (1950-1985) has revealed that mortality rate was increased by 22% in A-bomb survivors exposed to 1 Gy or more. When mortality of uterine cancer was investigated statistically using the 1968-1982 data for the population of the Research Institute for Nuclear Medicine and Biology, Hiroshima University, it was 1.2 times higher in the entire exposed group and 1.4 times higher in the group of proximally exposed A-bomb survivors (within 2 km from the hypocenter) than the non-exposed group, with statistically significant difference. It tended to be high in the group of distally exposed A-bomb survivors (who entered the city within 3 days after A-bombing) than the non-exposed group. When comparing the group of Hiroshima City with the group of Hiroshima Prefecture, mortality from uterine cancer was 1.3 times higher in the municipal group for proximally exposed A-bomb survivors and 1.3 times higher in the prefectural group for distally exposed A-bomb survivors and the others. Mortality rate was highest within one year after the acquisition of health handbook in the exposed group. (N.K.)

    Full Text Available The aim of this work was to synthesize methotrexate (MTX-polyamidoamine (PAMAM dendritic nanoconjugates and to study their effect on cell viability in uterine sarcoma cells. The amide-bonded PAMAM dendrimer-MTX conjugates were prepared by conjugation between the amine-terminated G5 dendrimer and the carboxylic groups of the MTX using a dicyclohexylcarbodiimide coupling reaction. The formation of conjugates was evaluated by ultraviolet (UV and 1 H nuclear magnetic resonance ( 1 H NMR spectroscopy studies. The cell survival of MES-SA cells, a uterine sarcoma cell line, was evaluated in the presence of the dendrimer-MTX nanoconjugate, using appropriate controls. The UV and 1 H NMR study confirmed the formation of covalent bonds between the drug and the dendrimer. The cell viability study indicated that the nanoconjugates had significantly improved cell killing compared to the free MTX.

    To investigate the immunological effect of Sizofilan (SPG) combined with radiotherapy, we evaluated the immunological parameters in 22 patients with uterine cervical cancer. Twelve patients were treated with SPG combined with radiotherapy (SPG group), and the other ten patients with radiotherapy only (control group). During radiotherapy, the numbers of lymphocyte and CD2 positive cell decreased in the SPG and control groups. After radiotherapy, however, its numbers in the SPG group became significantly higher than in the control group (p<0.05). The number of CD3 positive cell also presented a tendency to increase after radiotherapy in the SPG group. As for CD20 positive cell, its numbers were kept unchanged after radiotherapy in both groups, and no significant difference was observed between them. NK cell activity decreased during radiotherapy in both groups. After radiotherapy, its activity in the SPG group recovered to its pre-value and became significantly higher than that in the control group (p<0.05). SPG did not have any prominent effect on CD4/CD8 ratio. The adverse effect of SPG to liver or kidney function was not observed in our patients. The SCC level in the SPG group decreased rapidly by radiotherapy as well as that in the control group, and no significant difference was observed in SCC levels between them. So it was suggested that SPG did not suppress the cytocidal effect of radiation to cancer cells. Based on these findings, it was concluded that SPG prompted the recovery of not only lymphocyte, especially T cell, but also NK cell activity. These immunological findings presented a usefulness of clinical application of SPG to radiotherapy in patients with uterine cervical cancer. (author)

    Background The benefits of endoscopic testing for colorectal-cancer screening are uncertain. We evaluated the effect of screening with flexible sigmoidoscopy on colorectal-cancer incidence and mortality. Methods From 1993 through 2001, we randomly assigned 154,900 men and women 55 to 74 years of age either to screening with flexible sigmoidoscopy, with a repeat screening at 3 or 5 years, or to usual care. Cases of colorectal cancer and deaths from the disease were ascertained. Results Of the 77,445 participants randomly assigned to screening (intervention group), 83.5% underwent baseline flexible sigmoidoscopy and 54.0% were screened at 3 or 5 years. The incidence of colorectal cancer after a median follow-up of 11.9 years was 11.9 cases per 10,000 person-years in the intervention group (1012 cases), as compared with 15.2 cases per 10,000 person-years in the usual-care group (1287 cases), which represents a 21% reduction (relative risk, 0.79; 95% confidence interval [CI], 0.72 to 0.85; Pcolorectal cancer (479 cases in the intervention group vs. 669 cases in the usual-care group; relative risk, 0.71; 95% CI, 0.64 to 0.80; Pcolorectal cancer (512 cases vs. 595 cases; relative risk, 0.86; 95% CI, 0.76 to 0.97; P = 0.01). There were 2.9 deaths from colorectal cancer per 10,000 person-years in the intervention group (252 deaths), as compared with 3.9 per 10,000 person-years in the usual-care group (341 deaths), which represents a 26% reduction (relative risk, 0.74; 95% CI, 0.63 to 0.87; Pcolorectal cancer was reduced by 50% (87 deaths in the intervention group vs. 175 in the usual-care group; relative risk, 0.50; 95% CI, 0.38 to 0.64; Pcolorectal cancer was unaffected (143 and 147 deaths, respectively; relative risk, 0.97; 95% CI, 0.77 to 1.22; P = 0.81). Conclusions Screening with flexible sigmoidoscopy was associated with a significant decrease in colorectal-cancer incidence (in both the distal and proximal colon) and mortality (distal colon only).

    Rectal injury is one of the major side effects after radiation therapy for carcinoma of the uterine cervix. According to our previous reports, the cases of rectal complication were mainly related to the measured rectal dose in half of patients, and the other causes were related to the following factors; such as diabetes mellitus, hemorrhagic tendency, syphilis and so on. Concerning to rectal complication, these factors were investigated by means of the discriminant analysis, one of the multivariate analyses, in this paper. Twenty-eight factors as to radiation dose, laboratory tests and physical condition of patients were analyzed. From August 1978 through January 1980, 52 cases of previously untreated carcinoma of the uterine cervix were treated using RALS, remotely controlled high dose rate intracavitary radiotherapy, at our department. The data from 49 out of 52 cases were available for the discriminant analysis. By m eans of this analysis, it was found that these factors, such as the dose of whole pelvic irradiation, Point A dose of RALS, measured rectal dose by RALS, WGC-Z and TPHA were important factors for occurence of rectal complication. According to the discriminant score, 46 out of 49 cases (94 %) could be correctly discriminated. There were two cases of false positive and one false negative. Form February 1980 through July 1980, 27 cases of previously untreated carcinoma of the uterine cervix were treated at our department. The obtained discriminant function was applied to these 27 cases, and 24 out of 27 cases (89 %) were correctly predicted. There were two cases of false positive, and one of false negative. Discriminant analysis is useful for the prediction of rectal complication after radiation therapy for carcinoma of the uterine cervix. (J.P.N.)

    The measuremet of the serum level of squamous cell carcinoma-related antigen (SCC) purified from liver metastasis of cancer of the uterine cervix by an RIA kit is basically evaluated. The results of sensitivity, the recovery test, dilution test and variance test are good enough for clinical application. In gynecological disorders, the possitive rate is high (62 % [29/47]) in patients with cancer of the uterine cervix. Furthermore, the rate and level are related with the clinical staging. The changes of the serum SCC level in irradiated patients with cancer of the uterine cervix were a good reflection of the effectiveness of the treatment. (author)

    Purpose: External irradiation followed by intracavitary therapy (EBIC) has been considered the standard treatment for stage III-B cancer of the uterine cervix. For different reasons, some patients are not suited for intracavitary therapy (ICT), and the treatment may be given entirely by external beam irradiation alone (EBRTA). The purpose of our study is to discuss treatment results and complications for patients undergoing EBIC or EBRTA. Methods and Materials: A retrospective study was carried out on 202 eligible patients with stage III-B cancer of the uterine cervix admitted for radiotherapy from 1980-1997. Ninety-three patients were able to receive EBIC (50 Gy, 8 MV RX whole pelvis followed by one session of 38-45 Gy ICT to point A). The remaining received EBRTA (50-70 Gy for 5-9 or more weeks). Median follow-up procedure was 18.5 months (range: 4-182) for all patients and 26 months (range 4-147) for the patients at risk. Results: The most frequent reason for precluding ICT was large residual tumor volume (32.1%). Ten-year overall survival rates, relapse free survival, and pelvic failure rate for the EBIC and EBRTA patients were, respectively, 22.5% x 15.6% (p = 0.0087), 23.5% x 14.8% (p = 0.005), and 51.6% x 68.8% (p = 0.005). However, when the same comparisons were performed with EBIC patients x EBRTA patients receiving a high dose schedule (60 Gy/6-8 wk to 70 Gy/7-9 wk), the results of the EBIC group remained higher, but the differences became insignificant: respectively, 22.5% x 18.9% (p = 0.17), 23.5% x 15.3% (p = 0.052), and 51.6% x 60.0% (p = 0.10). The distribution of complications was similar in both groups. Conclusions: We found that EBIC was the best treatment modality in our patients with stage III-B cancer of the uterine cervix, whereas for patients who were not candidates for ICT, EBRTA with a high dose schedule appears to be an efficient and safe alternative

    Thickened uterine endometrium with abnormal uterine bleeding highly suggests endometrial hyperplasia or endometrial carcinoma. A case of 35-year-old nulliparous woman came to our department with endometrial mass manifesting as endometrial cancer. Transrectal ultrasonography and magnetic resonance imaging (MRI) showed an 8x6 cm multicystic, ill-defined mass compacted at the uterine endometrium, the anterior wall of the uterus, and 3x3 cm heterogenous mass at the left adnexa. The edometrial mass showed multiple septations with enhancement and low-signal intensity on T2-weighted images. After endometrial biopsy was done and simple hyperplasia without atypia was observed at the histopathologic finding, the patient underwent robot-assisted laparoscopy and diagnosed as adenomyoma at the frozen pathology. After adenomyomectomy, permanent pathologic analysis revealed the same result and she recovered without any complications and responded well to gonadotropin-releasing hormone (GnRH) agonist therapy.

    Hypothyroidism following total laryngectomy or radiotherapy treatment for laryngeal cancer is not a rare event, especially in advanced stages. There are no reports on the incidence of hypothyroidism in patients who received chemotherapy and radiotherapy. The objective of this study is to determine the incidence of thyroid dysfunction in a group of patients with laryngeal cancer who underwent surgery as sole treatment, total laryngectomy or radiotherapy alone, and patients with combined treatment: surgery plus radiotherapy, concomitant chemoradiation therapy and chemoradiation therapy plus salvage surgery. A prospective study of patients diagnosed with laryngeal cancer whose serum TSH and T4 levels were evaluated in a serial fashion. 70 patients with laryngeal cancer were studied; the average age at diagnosis was 70.2 years. Male patients were more affected, with a men-women ratio of 3.6:1. Glottic localization was the most frequent (44%). 64% of tumors were locally advanced carcinomas and 51% received multimodal treatment. 45 patients (63%) were diagnosed with hypothyroidism; 49% of the patients with subclinical hypothyroidism, and 51% with clinical hypothyroidism. Hypothyroidism is a complication following treatment for laryngeal cancer. It is recommended to evaluate the thyroid function periodically for timely detection.

We ascertained all histologically confirmed cases of prostate cancer during the period July 2002 to December 2008 and reviewed each death registration citing prostate cancer over a 14-year period commencing January 1995. There were 1101 new cases for an incidence rate of 160.4 (95% Confidence Interval: 151.0–170.2 per 100,000 standardized to the US population. Comparable rates in African-American and White American men were 248.2 (95% CI: 246.0–250.5 and 158.0 (95% CI: 157.5–158.6 per 100,000, respectively. Prostate cancer mortality rates in Barbados ranged from 63.2 to 101.6 per 100,000, compared to 51.1 to 78.8 per 100,000 among African Americans. Prostate cancer risks are lower in Caribbean-origin populations than previously believed, while mortality rates appeared to be higher than reported in African-American men. Studies in Caribbean populations may assist understanding of disparities among African-origin populations with shared heredity.

    Background: In order to most appropriately allocate healthcare and research funding for cancer, it is important to have accurate population-based incidence data. The Saudi Cancer Registry (SCR) provides such information, covering the time period from 1994 to the present day. The current report concerns an overview of cancer incidence statistics for Saudi Arabia in 2012. Methods: The SCR collects data from healthcare facilities throughout the Kingdom of Saudi Arabia. All newly diagnosed cases of cancer are recorded, with information on site and histology. For the present report, age-standardised and age-specific incidence rates (ASR, AIR, respectively) were calculated, with attention to gender-specific and regional differences. Results: The total number of incident cases of cancer identified by the SCR in 2012 was 14,336, with 6,791 (47.5%) among males and 7,545 (52.6%) among females. Of this total, 11,034 cases (76.9%) occurred in patients of Saudi origin. For Saudi males, the overall ASR (inc. all cancer sites) was 78.1 per 100,000 people, while that for females was 86.7. Incidence varied by region, with the Eastern region and Riyadh displaying the highest ASRs for both males and females, and Hail and Jazan displaying the lowest. Incidence varied by gender, with colorectal cancer (13.3%), non-Hodgkin lymphoma (NHL; 8.4%), and leukaemia (8.2%) being the most common types in males, and breast (25.8%), thyroid (11.7%), and colorectal cancers (9.3%) being the most common in females. Conclusions: This analysis of cancer incidence in Saudi Arabia demonstrated significant differences according to gender, age, and region of the Kingdom. The data should help ensure the most appropriate allocation of resources, with the aim of minimising the healthcare burden associated with cancer. Creative Commons Attribution License

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid {sup 99m}Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

    Purpose: To evaluate the long-term results of computed tomography (CT)–planned high-dose-rate (HDR) brachytherapy (BT) for treating cervical cancer patients. Methods and Materials: CT-planned HDR BT was performed according to the adapted Group European de Curietherapie-European Society for Therapeutic Radiology and Oncology (GEC-ESTRO) recommendations in 216 consecutive patients with locally advanced cervical cancer, International Federation of Gynecology and Obstetrics (FIGO) stage IB to IVA, who were treated with conformal external beam radiation therapy and concomitant chemotherapy. We analyzed outcomes and late side effects evaluated according to the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer and Subjective, Objective, Management, Analysis evaluation scoring system and compared them with the results from a historical group. Results: The median age was 56 years (range, 32-83 years). The median follow-up time for living patients was 52 months (range 37-63 months). The 5-year cumulative incidence function for the local recurrence rate for patients with FIGO II and III was 5.5% and 20%, respectively (P=.001). The 5-year rates of overall survival (OS) and disease-free survival (DFS) were 66.4% and 58.5%, respectively. The relative risk of failure for OS and DFS for FIGO III in relation to FIGO II was 2.24 (P=.003) and 2.6 (P=.000) and for lymph node enlargement was 2.3 (P=.002) and 2 (P=.006), respectively. In 2 patients, rectovaginal fistula occurred, and in 1 patient, vesicovaginal fistula occurred without local progression. Comparison of late adverse effects in patients treated according to the GEC-ESTRO recommendations and in the historical group revealed a reduction in fistula formation of 59% and also a reduction in rectal grade 3 to 4 late toxicity of >59%. Conclusions: This is the largest report with mature data of CT-planned BT HDR for the treatment of cervical cancer with good local control and

    Full Text Available Abstract Background Data concerning incidence and prevalence of cancer in the different regions of Russia have traditionally not been provided on a basis that facilitated comparison with data from countries in western parts of Europe. The oncological hospital in Arkhangelsk, in co-operation with Universitetet i Tromsø (Norway, has established a population based cancer registry for Arkhangelskaja Oblast (AO. AO is an administrative unit with 1.3 million inhabitants in northwestern Russia. The aim of this investigation was to assess the content and quality of the AO cancer registry (AKR, and to present the site-specific cancer-incidence rates in AO in the period 1993–2001. Methods The population in this study consisted of all individuals registered as residents of AO. All new cancer cases in the period 1993 – 2001, registered the AKR, were included in the study (ICD-10: C00-C95, except for C77-78. The annual gender and age-group-specific population figures were obtained from the AO statistics office. Results A total of 34 697 cases of primary cancers were included. The age-adjusted (world standard incidence rate for all sites combined was 164/100 000 for women and 281/100 000 for men. The highest incidence was for cancer of the trachea, bronchus and lung (16.3% of all cases, whereof 88.6 % of the cases were among men. Among women, cancer of the breast constituted 15.9 percent of all cases. The age-adjusted incidences of the most frequent cancer sites among men were: lung (77.4/100 000; stomach (45.9; rectum (13.4; oesophagus (13.0; colon (12.2; bladder (11.6; and prostate cancer (11.1. Among women they were: breast (28.5; stomach (19.7; colon (12.2; and ovary cancer (9.0. Conclusion Our findings confirm and strengthen the indication that the incidences of stomach, larynx, liver, pancreas, prostate, colon, bladder and melanoma cancer are quite different in male populations in Russia compared to many other European countries. Among women, most

    The assessment of an integrated indicator of quality of life, indicators of emotional and cognitive functioning, indicators of fatigue, pain and sleep disorders at stages of the combined treatment at patients with uterine corpus cancer with cortisolemia of various expression is carried out. Psychosomatic disorders are least expressed at patients with the low and high level of a hydrocortisone whereas patients with intermediate levels of a hydro-cortisone have more expressed fatigue, the feeling of pain, essential sleep disorders is stronger. Clarification of the mechanisms involved to development of psychosomatic disturbances in patients with different expression of a cortisolemia is necessary for development of the individualized strategy of prophylaxis and treatment focused on conservation of quality of life

    Full Text Available Research Question: Does acceptance of family planning reduce the risk of uterine cervical cancer? Objective: To study the association between usage of contraceptive methods and cervical carcinogenesis. Study design: Case control study. Settings: Urban Area â€" Hospital Based. Participants: 160 women having different degrees of dysplasia and 173 women having normal pap smears. Statistical Analysis: Multivariate Analysis. Results: None of the three widely prevalent Family Planning practices viz. IUD condoms and tubectomy turned out to be significant in the development of dysplasia, however, age at consummation of marriage before 18 years and illiteracy were significant. Use of IUD offered protection against carcinoma in situ (CIS and disease of invasive nature. Non- users of condoms were also at risk marginally failing to attain statistical significance.

    The purpose of this study is to develop a procedure for eradicative brachytherapy that can deliver a curative boost dose to bulky (>4 cm) vaginal stump recurrence of uterine cancer without risk of damaging surrounding organs. We separated risk organs (the rectum and sigmoid) from the target during brachytherapy, with a hyaluronate gel injection into the pararectal space via the percutaneous paraperineal approach under local anesthesia. The rectum anchored to the sacrum by native ligament was expected to shift posteriorly. We encountered a patient with bulky stump recurrence of uterine cancer, approximately 8 cm in maximum diameter. She was complaining of abdominal pain and constipation due to bowel encasement. Following 50 Gy of external beam radiotherapy, we applied a single fraction of brachytherapy under gel separation and delivered 14.5 Gy (50.8 GyE: equivalent dose in 2-Gy fraction calculated with linear quadratic model at α/β=3) to the target. The gel injection procedure was completed in 30 min without complications. A total irradiation dose of 100.8 GyE was delivered to the target and the cumulative minimum dose to the most irradiated rectosigmoidal volume of 2 cc (cumulative D 2cc ) was calculated as 58.5 GyE with gel injection, and was estimated to be 96 GyE without. Over three years, the local stump tumor has completely disappeared, with no complications. Brachytherapy with a pararectal gel injection can be a safe and effective eradicative option for bulky vaginal stump recurrence. (author)

    Objective: To assess the clinical effects of uterine arterial embolization on uterine leiomyoma. Methods: The authors treated 21 patients with uterine leiomyoma by Seldinger's uterine arterial embolization. The 4.0 F Cobra catheter was laced into the double uterine arteries with Polyvinyl Alcohol Foam (PVA) particles as the embolization. At 3 and 6 months postoperatively, the authors investigated the effects of the embolization. Results: After uterine arterial embolization, the volume of uterine leiomyoma decreased and menorrhagia was under controlled. The symptoms of anemia and oppression were relieved. The physiologic functions of ovary and uterus were preserved completely. Conclusions: Uterine arterial embolization is an effective and less invasive way to treat uterine leiomyoma

    Full Text Available According to the ministry of Health, Labour and welfare of Japan, Cancer has been the leading cause of death in Japan since 1981. [1] As per the data in 2010, in Japan, one in every three deaths was due to cancer. [2] The Japanese Government has introduced so far, three terms of 10 years strategies for Cancer control since 1984 till date. The budget allocated for cancer control in 2009 was 52.5 billion yen in Japan. [3] Lung is the leading site for cancer in both males and females in Japan. In males, following the lung, stomach, liver, colon and pancreas are other leading sites while in the females, stomach, colon, pancreas and breast are the other leading sites.[1] In 2006, the cancer incidence was 694,000 and the male cancer incidence was 1.4 times as large as that of females. The peak age for cancer deaths in males is their fifties while in the females it is the sixties among Japanese. In addition to the conventional treatments such as surgery, radiotherapy and chemotherapy, some of other therapies in practice in Japan are the Hyperthermia [4] that uses high temperatures to kill or damage the cancer cells, the Ion Beam therapy using proton beams [5] to damage the DNA of the cells as cancer cells have high rate of cell divisions and lesser ability to repair DNA damage, the molecular targeted therapies that interfere with a specific molecular target involved in tumour growth and progression [6] and most importantly the autologous cell based Immunotherapies. Modern Cancer Immunotherapy started in the 1970s in Japan. The immunopotentiators using compounds from Bacteria, Beta Glucans from fungi were the first forms of modern Immunotherapy. Then was the era of direct injection of cytokines such as Interleukins, Interferons etc. The adverse effects associated with the injection of cytokines led to development of cell based Immunotherapies in the 1980s. [7] Immuno-cell therapies involve isolation of immune cells which are then processed and re

    Los Alamos County (LAC) is home to the Los Alamos National Laboratory, a U.S. Department of Energy (DOE) nuclear research and design facility. In 1991, the DOE funded the New Mexico Department of Health to conduct a review of cancer incidence rates in LAC in response to citizen concerns over what was perceived as a large excess of brain tumors and a possible relationship to radiological contaminants from the Laboratory. The study found no unusual or alarming pattern in the incidence of brain cancer, however, a fourfold excess of thyroid cancer was observed during the late-1980's. A rapid review of the medical records for cases diagnosed between 1986 and 1990 failed to demonstrate that the thyroid cancer excess had resulted from enhanced detection. Surveillance activities subsequently undertaken to monitor the trend revealed that the excess persisted into 1993. A feasibility assessment of further studies was made, and ultimately, an investigation was conducted to document the epidemiologic characteristics of the excess in detail and to explore possible causes through a case-series records review. Findings from the investigation are the subject of this report

    The protective effects of glutathione (GSH) against radiation were studied by the single, blind method in patients with carcinoma of the uterine cervix treated by radiotherapy. The background factors were same in the GSH group as in the control group. The results revealed that the occurrence of abnormal values of WBC, PLT, GOT, GPT and hematocrit in the GSH group were significantly lower than those in the control group by signed rank test, which suggests a possibility that GSH prevents these blood findings from becoming abnormal. In subjective or objective symptoms, the appearance of general lassitude was significantly reduced in the GSH group. Blood findings were studied in relation to NSD.

    A modified afterloading cervical applicator and intracavitary endocurietherapy application technique eliminates several problems associated with the Henschke cervical applicator, and conventional preloading technique. The Kumar cervical applicator minimizes patient discomfort, and improves patient mobility while reducing the tendency of the applicator to rotate during the 40 to 50 hours of uterine intracavitary endocurietherapy. The use of hygroscopic laminaria tent for gradual cervical dilatation in plate of manual cervical dilatation, and the use of inflatable Foley balloon threaded onto the tandem instead of vaginal packing, to separate the 137 Cesium sources away from the rectum and bladder, eliminate the need of general anesthesia for the majority of patients undergoing intracavitary endocurietherapy.

  15. Validity of thyroid cancer incidence data following the Chernobyl accident.

    Jargin, Sergei V

    2011-12-01

    The only clearly demonstrated cancer incidence increase that can be attributed to radiation from the Chernobyl accident is thyroid carcinoma in patients exposed during childhood or adolescence. Significant increases in thyroid disease were observed as soon as 4 y after the accident. The solid/follicular subtype of papillary carcinoma predominated in the early period after the accident. Morphological diagnosis of cancer in such cases, if no infiltrative growth is clearly visible, depends mainly on the nuclear criteria. Outdated equipment and insufficient quality of histological specimens impeded reliable evaluation of the nuclear criteria. Access to foreign professional literature has always been limited in the former Soviet Union. The great number of advanced tumors observed shortly after the accident can be explained by the screening effect (detection of previously neglected cancers) and by the fact that many patients were brought from non-contaminated areas and registered as Chernobyl victims. It is also worth noting that exaggeration of the Chernobyl cancer statistics facilitated the writing of dissertations, financing of research, and assistance from outside the former Soviet Union. "Chernobyl hysteria" impeded nuclear energy production in some countries, thus contributing to higher prices for fossil fuel. The concluding point is that since post-Chernobyl cancers tend on average to be in a later stage of tumor progression, some published data on molecular or immunohistochemical characteristics of Chernobyl-related cancers require reevaluation.

    In the preoperative evaluation for gastric cancer, high-resolution endoscopic technologies allow us to detect small accessory lesions. However, it is not known if the gastric remnant after partial gastrectomy for synchronous multiple gastric cancers has a greater risk for metachronous cancer. The purpose of this study was to determine the incidence of metachronous cancer in this patient subset compared with that after solitary cancer surgery. Data on a consecutive series of 1,281 patients gastrectomized for early gastric cancer from 1991 to 2007 were analyzed retrospectively. The 715 gastric remnants after distal gastrectomy were periodically surveyed by endoscopic examination in Shikoku Cancer Center. Among those surveyed cases, 642 patients were pathologically diagnosed with solitary lesion (SO group) and 73 patients with synchronous multiple lesions (MU group) at the time of the initial surgery. In the follow-up period, 15 patients in the SO group and 3 patients in the MU group were diagnosed as having metachronous cancer in the gastric remnant. The cumulative 4-year incidence rate was 1.9 % in the SO group and 5.5 % in the MU group. The difference did not reach the significant level by the log-rank test. The incidence of metachronous cancer is higher after multiple cancer surgery; however, the difference is not statistically significant.

    To decrease exposure dose from radium source to operators during the treatment of cancer of the uterine cervix, new-type storage container was manufactured and its usefullness was discussed. The new-type container manufactured for trial houses radium source, for intracavitary irradiation of cancer of the cervix, connecting with TAO-type applicator for afterloading. TLD 1200 Type was used for measurement of radiation dose, and radium 50 mCi was used per one case. The obtained results were as follows: Using the new-type container, 45-60% decrease of exposure dose in the hands and fingers and 44% decrease in the body were obtained. The exposure dose of persons engaged in work of radiotherapy for one week was only 2.2% of the maximum permissible exposure dose, The time treating radium source was shortened to 50% by using the new-type container, and the shortening of that time was a great factor of countermeasures for decreasing exposure dose to operators. From above-mentioned results, the new-type storage container can be put sufficiently to practical use as a storage container of radium source for intracavitary irradiation of cancer of the cervix (when using TAO type afterloading method).

  19. Using mortality data to estimate radiation effects on breast cancer incidence

    Hoel, D.G.; Dinse, G.E.

    1990-01-01

    In this paper we combine Japanese data on radiation exposure and cancer mortality with U.S. data on cancer incidence and lethality to estimate the effects of ionizing radiation on cancer incidence. The analysis is based on the mathematical relationship between the mortality rate and the incidence and lethality rates, as well as on statistical models that relate Japanese incidence rates to U.S. incidence rates and radiation risk factors. Our approach assumes that the risk of death from causes other than the cancer does not depend on whether or not the cancer is present, and among individuals with the cancer, the risk of death attributable to the cancer is the same in Japan and the U.S. and is not affected by radiation exposure. In particular, we focus on the incidence of breast cancer in Japanese women and how this incidence is affected by radiation risk factors. The analysis uses Japanese exposure and mortality data from the Radiation Effects Research Foundation study of atomic bomb survivors and U.S. incidence and lethality data from the Surveillance, Epidemiology, and End Results Registry. Even without Japanese incidence data, we obtain reasonable estimates of the incidence of breast cancer in unexposed Japanese women and identify the radiation risk factors that affect this incidence. Our analysis demonstrates that the age at exposure is an important risk factor, but that the incidence of breast cancer is not affected by the city of residence (Nagasaki versus Hiroshima) or the time since exposure

    1982-01-01

    A total body dose of 1000 R X radiation to 1252 male and 1366 female NEDH rats protected by permanent parabiosis to an untreated partner yielded respective cancer incidences of 42.7 and 38.3% within mean life-spans slightly less than single controls. These incidences were significant at the 1% level of probability compared with lower rates in shielded partners as well as in over 600 control parabiont partners and 700 single controls in which both sexes were nearly equally represented. Significant cancer incidences were induced in skin and islet cells of males, soft supporting tissue, renal tubules, bone of males and females, and ovary. Parabiosis per se provided local conditions conducive to the development of sarcomas, possibly enhanced by radiation, in anastomosed tissue as well as systemic changes promoting the spontaneous development of lymphoma and leukemia in females and inhibiting that of mammary carcinoma in females and malignant pheochromocytoma in males. The effects in females were largely canceled by radiation. The function of dose and its modification by factors contingent to parabiosis are discussed in relation to reported data on rats of other strains exposed to sublethal or lethal total-body X-ray doses

    Cancer is one of the leading causes of death worldwide and its incidence is expected to increase in the future. In Panama, cancer is also one of the leading causes of death. In 1964, a nationwide cancer registry was started and it was restructured and improved in 2012. The aim of this study is to utilize Joinpoint regression analysis to study the trends of the incidence and mortality of cancer in Panama in the last decade. Cancer mortality was estimated from the Panamanian National Institute of Census and Statistics Registry for the period 2001 to 2011. Cancer incidence was estimated from the Panamanian National Cancer Registry for the period 2000 to 2009. The Joinpoint Regression Analysis program, version 4.0.4, was used to calculate trends by age-adjusted incidence and mortality rates for selected cancers. Overall, the trend of age-adjusted cancer mortality in Panama has declined over the last 10 years (-1.12% per year). The cancers for which there was a significant increase in the trend of mortality were female breast cancer and ovarian cancer; while the highest increases in incidence were shown for breast cancer, liver cancer, and prostate cancer. Significant decrease in the trend of mortality was evidenced for the following: prostate cancer, lung and bronchus cancer, and cervical cancer; with respect to incidence, only oral and pharynx cancer in both sexes had a significant decrease. Some cancers showed no significant trends in incidence or mortality. This study reveals contrasting trends in cancer incidence and mortality in Panama in the last decade. Although Panama is considered an upper middle income nation, this study demonstrates that some cancer mortality trends, like the ones seen in cervical and lung cancer, behave similarly to the ones seen in high income countries. In contrast, other types, like breast cancer, follow a pattern seen in countries undergoing a transition to a developed economy with its associated lifestyle, nutrition, and body weight

    The prevalence of brain metastases (BM) from uterine cancer has recently increased because of the improvement of overall survival (OS) of patients with uterine cancer due to its early detection and improved local control as a result of new effective treatments. However, little information is available regarding their clinical characteristics and prognosis, because oncologists have encountered BM from uterine cancer on rare occasions. Records from 81 patients with uterine BM were collected from 10 institutes in Japan. These were used in a multi-institutional study to identify prognostic factors and develop a graded prognostic assessment (GPA) for patients with BM from uterine cancer. Median OS after the development of BM was 7 months (95% confidence interval, 4 to 10 months). Multivariate analysis revealed that there were survival differences according to the existence of extracranial metastases and number of BM. In the present uterine-GPA, a score of 0 was assigned to those patients with ≥5 BM and extracranial metastasis, a score of 2 was assigned to those patients with one to four BM or without extracranial metastasis, and a score of 4 was assigned to those patients with one to four BM and without extracranial metastasis. The median OS for patients with a uterine-GPA scores of 0, 2, and 4 was 3, 7, and 22 months, respectively. A survival analysis confirmed the presence of statistically significant differences between these groups (p Brain Tumor Registry of Japan. Uterine GPA incorporates two simple clinical parameters of high prognostic significance and can be used to predict the expected survival times in patients with BM from uterine cancer. Its use may help in determining an appropriate treatment for individual patients with BM.

    Treatment of choice for uterine cervix cancer stage IIB is radiotherapy. We analyzed survivals, prognostic factors, patterns of failure and complications. This is a retrospective analysis of 167 patients with stage IIB carcinoma of uterine cervix treated with curative external pelvic and high dose rate intracavitary radiotherapy at the Department of Therapeutic Radiology, Soonchunhyang University Hospital from August 1985 to August 1994. All the patients followed up from 3 to 141 months(mean 60 months) and age of patients ranged from 31 to 78 years at presentation(mean : 55 years). Overall complete response rate was 84%. The response rate for squamous cell carcimoma and adenocarcinoma were 86% and 60%, respectively. Overall 5-years survival rate and disease free survival rate was 62 and 59%, respectively. Mass size and treatment response were significant prognostic factors for survival. Pathologic type and parametrial involvement were marginally significants prognostic factors. Local failure was 43 cases, distant metastasis was 14 cases and local failure plus distant metastasis was 3 cases, and most of local failures occurred within 24 months, distant metastasis within 12 months after treatment. Twenty eight(16.8%) patients developed late rectal and urinary complications There were tendency to increasing severity and frequency according to increased fractional dose and total(rectal and bladder) dose. Survival rate was significantly related to tumor size and radiotherapy response. Tumor size should be considered in the clinical staging. To increased survival and local control, clinical trials such as decreasing duration of radiotherapy or addition of chemotherapy is needed. To detect early recurrence, regular follow up after RT is important. Because total rectal and bladder dose affected late complications, meticulous vaginal packing is needed to optimize dose of normal tissues and to decrease late complications.

  4. Regulation of DNA synthesis and the cell cycle in human prostate cancer cells and lymphocytes by ovine uterine serpin

    Hansen Peter J

    2008-01-01

    Full Text Available Abstract Background Uterine serpins are members of the serine proteinase inhibitor superfamily. Like some other serpins, these proteins do not appear to be functional proteinase inhibitors. The most studied member of the group, ovine uterine serpin (OvUS, inhibits proliferation of several cell types including activated lymphocytes, bovine preimplantation embryos, and cell lines for lymphoma, canine primary osteosarcoma and human prostate cancer (PC-3 cells. The goal for the present study was to evaluate the mechanism by which OvUS inhibits cell proliferation. In particular, it was tested whether inhibition of DNA synthesis in PC-3 cells involves cytotoxic actions of OvUS or the induction of apoptosis. The effect of OvUS in the production of the autocrine and angiogenic cytokine interleukin (IL-8 by PC-3 cells was also determined. Finally, it was tested whether OvUS blocks specific steps in the cell cycle using both PC-3 cells and lymphocytes. Results Recombinant OvUS blocked proliferation of PC-3 cells at concentrations as low as 8 μg/ml as determined by measurements of [3H]thymidine incorporation or ATP content per well. Treatment of PC-3 cells with OvUS did not cause cytotoxicity or apoptosis or alter interleukin-8 secretion into medium. Results from flow cytometry experiments showed that OvUS blocked the entry of PC-3 cells into S phase and the exit from G2/M phase. In addition, OvUS blocked entry of lymphocytes into S phase following activation of proliferation with phytohemagglutinin. Conclusion Results indicate that OvUS acts to block cell proliferation through disruption of the cell cycle dynamics rather than induction of cytotoxicity or apoptosis. The finding that OvUS can regulate cell proliferation makes this one of only a few serpins that function to inhibit cell growth.

  5. Further statement on the incidence of childhood cancer in Wales

    1999-01-01

    In March 1999 the Welsh Office asked COMARE to examine two unpublished studies. The first by Busby et al of ''Green Audit'' concluded that there was a significant excess of childhood leukaemia in North Wales associated with residential proximity to the coast. The second study, carried out by Steward et al of the Welsh Cancer Intelligence and Surveillance Unit (WCISU), did not support this conclusion. We were asked to advise as to whether we considered that there was a real raised incidence of childhood leukaemia near the coast of North Wales and whether further study was required. To do this we initially organised a comparison of the figures quoted by both the Green Audit and WCISU with the database held by the Childhood Cancer Research Group (CCRG) in Oxford. This group maintains the National Registry of Childhood Tumours (NRCT), data for which are supplied from a variety of sources including cancer registries but also directly from medical cancer specialists as well as from death certificates. As a consequence this provides an independent check on much of the data on childhood cancer held by cancer registries in Great Britain and is clinically validated. After carrying out the independent check on the number of cases of childhood leukaemia in these Welsh counties it was immediately apparent that the data held by Green Audit, on which the analysis by Busby et al was based, were incorrect. These data were received from the Welsh Cancer Registry (WCR) in 1995. A further data set was received from WCR in 1996 but was not used in the analysis by Busby et al. In June 1999 we issued a statement to the Welsh Office. In that statement we noted that Dr Busby and his colleagues appeared to have used erroneous data in their study. On the basis of the Steward et al data, COMARE also stated that we found no evidence to support the contention that there is an increased incidence of childhood leukaemia or other childhood cancers amongst the Welsh population living close to the

    The incidence of new primary cancers was evaluated in 3538 postmenopausal patients who had received surgical treatment for primary breast cancer. Of these patients, 1828 with a low risk of recurrence received no further treatment. High-risk patients were randomly assigned to one of two groups. The first group (n = 846) received postoperative radiotherapy, while the second group (n = 864) received radiotherapy plus tamoxifen at a dose of 30 mg given daily for 48 weeks. The median observation time was 7.9 years. In comparison with the number of new cancers in the general population, the number of new cancers in the three groups was elevated mostly due to a high number of cancers of the contralateral breast and of colorectal cancers in the high-risk groups. The cumulative risk of nonlymphatic leukemia was increased among patients who received postoperative radiotherapy (P = .04). Cancer incidence in the high-risk tamoxifen-treated group relative to that in the high-risk group not treated with tamoxifen was not significant (1.3). No protective effect of tamoxifen on the opposite breast was seen (rate ratio for breast cancer = 1.1), but a tendency to an elevated risk of endometrial cancer was observed (rate ratio = 3.3; 95% confidence interval = 0.6-32.4). Continued and careful follow-up of women treated with tamoxifen is necessary to clarify the potential cancer-suppressive or cancer-promoting effects of this drug

    High-level occupational radon exposure is an established risk factor for lung cancer. We assessed the long-term association between residential radon and lung cancer risk using a prospective Danish cohort using 57,053 persons recruited during 1993-1997. We followed each cohort member for cancer occurrence until 27 June 2006, identifying 589 lung cancer cases. We traced residential addresses from 1 January 1971 until 27 June 2006 and calculated radon at each of these addresses using information from central databases regarding geology and house construction. Cox proportional hazards models were used to estimate incidence rate ratios (IRR) and 95% confidence intervals (CI) for lung cancer risk associated with residential radon exposure with and without adjustment for sex, smoking variables, education, socio-economic status, occupation, body mass index, air pollution and consumption of fruit and alcohol. Potential effect modification by sex, traffic-related air pollution and environmental tobacco smoke was assessed. Median estimated radon was 35.8 Bq/m{sup 3}. The adjusted IRR for lung cancer was 1.04 (95% CI: 0.69-1.56) in association with a 100 Bq/m{sup 3} higher radon concentration and 1.67 (95% CI: 0.69-4.04) among non-smokers. We found no evidence of effect modification. We find a positive association between radon and lung cancer risk consistent with previous studies but the role of chance cannot be excluded as these associations were not statistically significant. Our results provide valuable information at the low-level radon dose range.

    The large international variation in the incidence of prostate cancer (PC) is well known but the underlying reasons are not understood. We want to compare PC incidence and survival among immigrants to Sweden in order to explain the international differences. Cancer data were obtained from the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for PC in first-degree immigrants by country of birth. The immigrants were classified into four groups by SIR and area of origin. Survival in PC was assessed by hazard ratio (HR) in the four groups. In some analyses, clinical stage of PC was assessed by the tumor, node, and metastasis classification. The SIR was 0.47 (95% confidence interval 0.43-0.51) for immigrants with the lowest risk, constituting men from Turkey, Middle East, Asia, and Chile. The HR was 0.60 (0.45-0.81) for these men and it was 0.49 if they had stayed 20+ years in Sweden. The SIR in screening detected PC, T1c, was 0.55. Among these men, screening detected PC constituted 34.5% of all PC, compared to 29.0% among Swedes (p = 0.10). The results showed that the non-European immigrants, of mainly Middle East, Asian, and Chilean origin, with the lowest risk of PC, also had the most favorable survival in PC. As the available clinical features of PC at diagnosis or the distribution of known risk factors could not explain the differences, a likely biological mechanism through a favorable androgenic hormonal host environment is suggested as an explanation of the observed effects.

  10. Thyroid Gland Metastasis from Cancer of the Uterine Cervix: An Extremely Rare Case Report.

    The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

    Full Text Available Background & Objectives: Colorectal cancer is considered as the third prevalent malignancy worldwide. Investigation of information on cancers in Iran during 1985-1996 showed an increase in the incidence and prevalence of colorectal cancer. Its rank in Iran has increased from 9 to 5th during 10 years. It was reported as high prevalent cancer in Iranian people aged less than 40 years among Asian countries.   Methods: In this cases-control study patients with a pathologic report of colorectal cancer were recruited among those cases registered in Ardabil Cancer Registry. Control group were selected from neighbors, frequency matched for age and gender. Subjects were interviewed using a questionnaire consisting information on age, gender, smoking, drugs and alcohol consuming, diet, family history of cancer and serum IgM and IgG level for H. pylori. Data were analyzed using SPSS v16.   Results: In the current study, 43 persons (53.8% were male and 37 (46.2% were female. In the case group, 10 persons (12.5% were under 40, 34 cases (42.5% in age group of 41- 60 and 36 persons (45% were more than 61 years. In the control group 12 persons (15% were under 40, 36 persons (45.5% in age group of 41-60 and 40 persons (68% were more than 61 years. In the control group 3 cases had BMI less than 19, 36 cases (45% between 19-24.9, 31 cases (38.8% between 25-29.9 and 10 cases (12.5% were more than 30, whereas this variable was 2.5, 32.5, 46.2 and 18.8% respectively in the case group.   Positive history of smoking found to increase the risk of cancer around 1.8 times (OR= 1.78 CI: 0.91- 5.85. However, significant difference was not observed between two groups regarding alcoholic beverage consumption (p=0.385 . There were significant differences between two groups in terms of vegetables and carbohydrates intake. Difference was also significant between two groups regarding positive level of IgG.

    Full Text Available Background Cervical cytology for uterine cervical cancer screening has transitioned from conventional smear (CS to liquid-based cytology (LBC, which has many advantages. The aim of this study was to compare the proportion of unsatisfactory specimens from CS versus LBC at multiple institutions including general hospitals and commercial laboratories. Methods Each participating institution provided a minimum of 500 Papanicolaou (Pap test results for analysis. Pap tests were classified according to the participating institution (commercial laboratory or general hospital and the processing method (CS, ThinPrep, SurePath, or CellPrep. The causes of unsatisfactory results were classified as technical problems, scant cellularity, or complete obscuring factors. Results A total of 38,956 Pap test results from eight general hospitals and three commercial laboratories were analyzed. The mean unsatisfactory rate of LBC was significantly lower than that of CS (1.26% and 3.31%, p = .018. In the LBC method, samples from general hospitals had lower unsatisfactory rates than those from commercial laboratories (0.65% vs 2.89%, p = .006. The reasons for unsatisfactory results were heterogeneous in CS. On the other hand, 66.2% of unsatisfactory results in LBC were due to the scant cellularity. Conclusions Unsatisfactory rate of cervical cancer screening test results varies according to the institution and the processing method. LBC has a significantly lower unsatisfactory rate than CS.

    Glyphosate is the most commonly used herbicide worldwide, with both residential and agricultural uses. In 2015, the International Agency for Research on Cancer classified glyphosate as "probably carcinogenic to humans," noting strong mechanistic evidence and positive associations for non-Hodgkin lymphoma (NHL) in some epidemiologic studies. A previous evaluation in the Agricultural Health Study (AHS) with follow-up through 2001 found no statistically significant associations with glyphosate use and cancer at any site. The AHS is a prospective cohort of licensed pesticide applicators from North Carolina and Iowa. Here, we updated the previous evaluation of glyphosate with cancer incidence from registry linkages through 2012 (North Carolina)/2013 (Iowa). Lifetime days and intensity-weighted lifetime days of glyphosate use were based on self-reported information from enrollment (1993-1997) and follow-up questionnaires (1999-2005). We estimated incidence rate ratios (RRs) and 95% confidence intervals (CIs) using Poisson regression, controlling for potential confounders, including use of other pesticides. All statistical tests were two-sided. Among 54 251 applicators, 44 932 (82.8%) used glyphosate, including 5779 incident cancer cases (79.3% of all cases). In unlagged analyses, glyphosate was not statistically significantly associated with cancer at any site. However, among applicators in the highest exposure quartile, there was an increased risk of acute myeloid leukemia (AML) compared with never users (RR = 2.44, 95% CI = 0.94 to 6.32, Ptrend = .11), though this association was not statistically significant. Results for AML were similar with a five-year (RRQuartile 4 = 2.32, 95% CI = 0.98 to 5.51, Ptrend = .07) and 20-year exposure lag (RRTertile 3 = 2.04, 95% CI = 1.05 to 3.97, Ptrend = .04). In this large, prospective cohort study, no association was apparent between glyphosate and any solid tumors or lymphoid malignancies overall, including NHL and

    While both the 2012 and 2014 Consumer Reports concerned arsenic levels in US rice, no previous study has evaluated long-term consumption of total rice, white rice and brown rice in relation to risk of developing cancers. We investigated this in the female Nurses' Health Study (1984-2010), and Nurses' Health Study II (1989-2009), and the male Health Professionals Follow-up Study (1986-2008), which included a total of 45,231 men and 160,408 women, free of cancer at baseline. Validated food frequency questionnaires were used to measure rice consumption at baseline and repeated almost every 4 years thereafter. We employed Cox proportional hazards regression model to estimate multivariable relative risks (RRs) and 95% confidence intervals (95% CIs). During up to 26 years of follow-up, we documented 31,655 incident cancer cases (10,833 in men and 20,822 in women). Age-adjusted results were similar to multivariable-adjusted results. Compared to participants with less than one serving per week, the multivariable RRs of overall cancer for individuals who ate at least five servings per week were 0.97 for total rice (95% CI: 0.85-1.07), 0.87 for white rice (95% CI: 0.75-1.01), and 1.17 for brown rice (95% CI: 0.90-1.26). Similar non-significant associations were observed for specific sites of cancers including prostate, breast, colon and rectum, melanoma, bladder, kidney, and lung. Additionally, the null associations were observed among European Americans and non-smokers, and were not modified by BMI. Long-term consumption of total rice, white rice or brown rice was not associated with risk of developing cancer in US men and women. © 2015 UICC.

    Full Text Available Introduction: patients with sporadic colorectal cancer or cases associated with syndromes are at risk of having synchronous or metachronous cancer. Although it is an important subject, Brazilian data on the subject are scarce. Objective: to evaluate the incidence and epidemiological features in patients with synchro- nous and metachronous colorectal cancer in a reference service of proctology in the Rio Grande do Sul. Methods: cross-sectional observational study, performed between January and July 2012, analyzing all patients admitted in the service that met the inclusion criteria. A retrospective review of records was performed, noting demographic variables, comorbidi- ties and tumor-related variables. Results: 150 records were analyzed, of which 53.3% were males and mean age was 63 (± 13.01 years old. The most frequently found tumor location was the sigmoid colon and high rectum (50.67%, followed by the lower rectum (36%. Adenocarcinomas were the most prevalent histological subtype (88%, followed by epidermoid tumors (1.33%. Hereditary syndromes were identified in five patients (3.33%, with four being Familial adenomatous polyposis (FAP and one hereditary nonpolyposis colorectal cancer (HNPCC. Among the an- alyzed patients, four (2.67% had synchronous and one (0.67% had metachronous cancer. Conclusion: the incidence of synchronous and metachronous colorectal cancer was, respectively, 2.67% and 0.67%, results that corroborate those reported in international literature.

    Background: The International Agency for Research on Cancer has classified outdoor air pollution (fine particulate matter [PM2.5]) as a Group 1 lung carcinogen in humans. We aimed to estimate the proportion of lung cancer cases attributable to PM2.5 exposure in Alberta in 2012. Methods: Annual average concentrations of PM2.5 in 2011 for 22 communities across Alberta were extracted from the Clean Air Strategic Alliance Data Warehouse and were population-weighted across the province. Using 7.5 µg/m3 and 3.18 µg/m3 as the annual average theoretical minimum risk concentrations of PM2.5, we estimated the proportion of the population above this cut-off to determine the population attributable risk of lung cancer due to PM2.5 exposure. Results: The mean population-weighted concentration of PM2.5 for Alberta in 2011 was 10.03 µg/m3. We estimated relative risks of 1.02 and 1.06 for theoretical minimum risk PM2.5 concentration thresholds of 7.5 µg/m3 and 3.18 µg/m3, respectively. About 1.87%-5.69% of incident lung cancer cases in Alberta were estimated to be attributable to PM2.5 exposure. Interpretation: Our estimate of attributable burden is low compared to that reported in studies in other areas of the world owing to the relatively low levels of PM2.5 recorded in Alberta. Reducing PM2.5 emissions in Alberta should continue to be a priority to help decrease the burden of lung cancer in the population. PMID:28659352

    One hundred and twelve cases of thyroid cancer diagnosed during the period 1958-79 among the extended Life Span Study cohort in Hiroshima and Nagasaki were studied. There was a statistically significant association between thyroid cancer incidence and exposure to atomic bomb radiation. The adjusted excess relative risk (ERR) per gray was 1.1 (95% confidence interval=0.3-2.5) and the adjusted absolute risk per 10 4 PYGy was 0.59 (95% confidence interval=0.2-1.7). Based on a comparison of the deviances obtained from relative and absolute risk models, a simple linear relative risk model appeared to fit the data better than an absolute risk model; however, it would not be appropriate to conclude that the data conform strictly to a relative risk pattern. The incidence of thyroid cancer among the members of the Adult Health Study (AHS) population, who have received biennial medical examinations at the Atomic Bomb Casualty Commission and its successor the Radiation Effects Research Foundation, since 1958, was 70% higher than that among the rest of the extended LSS cohort after adjustments for city, sex, log age, calendar year, and Dosimetry System 1986 dose. There was no significant difference between the slope of the dose-response curve for AHS and non-AHS participants, although the estimated ERRs at 1 Gy for the AHS and non-AHS population were 1.6 and 0.3, respectively. The elevated risk appeared to be confined to women, and there was an increasing risk with decreasing attained age and age at exposure. (J.P.N.)

    The objective of this study was to develop a consensus-based guideline to define clinical target volume for primary disease (clinical target volume primary) in external beam radiotherapy for intact uterine cervical cancer. The working subgroup of the Japan Clinical Oncology Group (JCOG) Radiation Therapy Study Group began developing a guideline for primary clinical target volume in November 2009. The group consisted of 10 radiation oncologists and 2 gynecologic oncologists. The process started with comparing the contouring on computed tomographic images of actual cervical cancer cases among the members. This was followed by a comprehensive literature review that included primary research articles and textbooks as well as information on surgical procedures. Extensive discussion occurred in face-to-face meetings (three occasions) and frequent e-mail communications until a consensus was reached. The working subgroup reached a consensus on the definition for the clinical target volume primary. The clinical target volume primary consists of the gross tumor volume, uterine cervix, uterine corpus, parametrium, vagina and ovaries. Definitions for these component structures were determined. Anatomical boundaries in all directions were defined for the parametrium. Examples delineating these boundaries were prepared for the posterior border of the parametrium for various clinical situations (id est (i.e.) central tumor bulk, degree of parametrial involvement). A consensus-based guideline defining the clinical target volume primary was developed for external beam radiotherapy for intact uterine cervical cancer. This guideline will serve as a template for radiotherapy protocols in future clinical trials. It may also be used in actual clinical practice in the setting of highly precise external beam radiotherapy, including intensity-modulated radiotherapy. (author)

    Osteoporosis is common in prostate cancer (CaP) patients both before and after institution of androgen deprivation therapy and is associated with significant morbidity. Lactose intolerance (LI) can affect bone mass but has not been studied in this group of patients. The objective of this study was to compare the incidence of LI in CaP patients with that in the general population and to identify factors affecting lactose intolerance in CaP patients. Fifty-five men with CaP planned for bilateral orchidectomy were enrolled in the study and their baseline characteristics including age, weight, height, body mass index (BMI), prostate-specific antigen, serum calcium profile, lactose tolerance status, physical activity, alcohol intake and smoking, bone mineral density and calcium intake were registered. The data on lactose tolerance in these patients were compared with those of 81 age-matched controls (data taken from the available database). The incidence of LI in CaP patients was significantly less than that in the control group (36.2% and 58.3%, respectively, p = 0.027). A significantly greater number of CaP patients in the lactose-tolerant group had a calcium intake of >1500 mg/day (p = 0.03) and that of milk >500 ml/day (p = 0.05) than those in the intolerant group. Age >70 years, BMI 163 cm, lower physical activity and co-abuse of alcohol and smoking significantly correlated with the presence of LI (p 25 kg/m2 and weight >65 kg. The incidence of LI in CaP patients is less than that in the general population despite a higher incidence of osteoporosis, indicating a complex etiology of CaP-related osteoporosis. Certain physical characteristics and personal habits are important in determining lactose-tolerant status.

    Full Text Available Stomach cancer is the second most common cancer in Eastern Asia, accounting for approximately 50% of all new cases of stomach cancer worldwide. Our objective was to compare the stomach cancer incidence rates of Asian Americans in Los Angeles with those of native Asians to assess the etiology of stomach cancer from 1988 to 2011. To examine these differences, Asian Americans (Korean, Japanese, Chinese, and Filipino Americans living in Los Angeles, California, USA and native Asians (from Korea, Japan, China, and the Philippines were selected for this study. Using the Cancer Incidence in Five Continents database, stomach cancer incidence rates were examined. Data from the National Cancer Registry of Korea were used for native Koreans. Between native countries, the incidence rates in Japan, China, the Philippines, and the US declined over time, but the incidence in Korea has remained constant. The incidences among Asian immigrants were lower than those among native Asians. The incidence rates of males were approximately 2 times higher than those among females in Asian countries were. The effect of immigration on stomach cancer incidence suggests that lifestyle factors are a significant determinant of stomach cancer risk. However, the incidence in Korea remains the highest of these countries

    From January 1980 through April 1990, a total of 317 patients with an oral cancer were treated with radiation therapy at Department of Radiology, Osaka University Hospital. Twenty-seven (8.5%) of these 317 patients had other primary cancers. For statistical purposes, the expected number of other primary cancers was estimated by multiplying the age-sex specific incidence rates among Osaka residents with the Person-year at risk figures, based on the Osaka Prefectural Cancer Registry. The observed/expected [0/E] ratios were 16.00 (p<0.01) for the esophagus and 28.42 (p<0.01) for the oropharynx. The present study suggested the necessity of following up oral cancer patients, especially those who have had carcinoma of the mouth floor, in order to enable the early diagnosis of upper digestive tract cancer.

    Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

    Introduction The annual incidence of thyroid cancer is known to vary with geographic area, age and gender. The increasing incidence of thyroid cancer has been attributed to increase in detection of micropapillary subtype, among other factors. The aim of the study was to investigate time trends in the incidence of thyroid cancer in Singapore, an iodine-sufficient area. Materials and methods Data retrieved from the Singapore National Cancer Registry on all thyroid cancers that were diagnosed from 1974 to 2013 were reviewed. We studied the time trends of thyroid cancer based on gender, race, pathology and treatment modalities where available. Results The age-standardised incidence rate of thyroid cancer increased to 5.6/100,000 in 2013 from 2.5/100,000 in 1974. Thyroid cancer appeared to be more common in women, with a higher incidence in Chinese and Malays compared with Indians. Papillary carcinoma is the most common subtype. The percentage of papillary microcarcinoma has remained relatively stable at around 38% of all papillary cancers between 2007 and 2013. Although the incidence of thyroid cancer has increased since 1974, the mortality rate has remained stable. Conclusion This trend of increase in incidence of thyroid cancer in Singapore compares with other published series; however, the rise seen was not solely due to micropapillary type. Thyroid cancer was also more common in Chinese and Malays compared with Indians for reasons that needs to be studied further.

  9. Interobserver variation in rectal and bladder doses in orthogonal film-based treatment planning of cancer of the uterine cervix

    2008-01-01

    Full Text Available Orthogonal film-based treatment planning is the most commonly adopted standard practice of treatment planning for cancer of the uterine cervix using high dose rate brachytherapy (HDR. This study aims at examining the variation in rectal and bladder doses when the same set of orthogonal films was given to different observers. Five physicists were given 35 pairs of orthogonal films obtained from patients who had undergone HDR brachytherapy. They were given the same instructions and asked to plan the case assuming the tumor was centrally placed, using the treatment-planning system, PLATO BPS V13.2. A statistically significant difference was observed in the average rectal (F = 3.407, P = 0.01 and bladder (F = 3.284, P = 0.013 doses and the volumes enclosed by the 100% isodose curve ( P < 0.01 obtained by each observer. These variations may be attributed to the differences in the reconstruction of applicators, the selection of source positions in ovoids and the intrauterine (IU tube, and the differences in the selection of points especially for the rectum, from lateral radiographs. These variations in planning seen within a department can be avoided if a particular source pattern is followed in the intrauterine tube, unless a specific situation demands a change. Variations in the selection of rectal points can be ruled out if the posterior vaginal surface is clearly seen.

    The clinical features, magnifying colonoscopic findings and pathological findings of acute radiation proctitis were investigated in 40 cases of uterine cervix cancer and the following results were obtained. 1)As a clinical simptom, diarrhea was observed in about half of all cases. 2)The value of serum total protein and number of leukocyte decreased until the dose of 30 Gy (3000 rads) and no remarkable change of them were observed afterwards. Hemoglobin value did not change throughout the whole clinical course. 3)Magnifying colonoscopic findings showed remarkable change with increase of the dose and especially irregularity of pit was observed in all cases. 4)In pathological findings, edema, degenerative change of epitherial cells and decreased number of goblet cells were observed from the beginning. In cases that received more than 50 Gy (5000 rads), fibrosis developed and the epithelium showed strong regeneration. Also Paneth cells were observed in 5 out of 40 cases. 5)Remarkable change was not observed before or after the radiation by barium enema. (author)

    1 - 2 pieces per a day of Sheroproct suppository were given to 22 cases which were suffered from rectitis or rectal hemorrhage during or after radiotherapy of cancer of the uterine cervix. The effects were judged as follows according to the degree of main symptoms such as pain, hemorrhage and mucous stool: marked effectiveness (the symptoms decreased within three days and disappeared within one week), effectiveness (it takes over four days to decrease the symptoms and the symptoms disappeared within one week, and a little effectiveness (the symptoms disappeared within one or two weeks). As to pain in 20 cases, marked effectiveness was recognized in 11 cases, a little effectiveness in 3 cases, and no effectiveness in one case. In 16 cases of acute inflamation induced during radiotherapy, 9 cases showed markedly effective, 4 cases showed effective, and one case showed no effective. On improvement of mucous stool, this drug was effective in acute rectitis, but it was not effective in chronic cases. There was little effect in rectal hemorrhage after the radiotherapy. It was suggested that this drug was useful to treat pain of rectitis. (Tsunoda, M.)

    A 65-year-old woman had received a panhysterectomy and radiation therapy for a uterine cancer in 1974 and underwent a drainage operation for a peritonitis due to rupture of the bladder associated with radiation cystitis in 1983. A rectovesical fistula was revealed and partial resection of the bladder and rectum was performed in 1996. In 1998, rectovesical fistula recurred and symptom of fecaluria and contact-type dermatitis at perineal region subsequently worsened. In February, 2000, colonoscopy and gastrograffin-enema revealed a giant recto-vagino-vesical fistula. Although we recommended ileostomy, the patient refused our offer. She gave informed consent to our proposal about the insertion of a covered expandable metallic stent (EMS) into the rectum to treat for fecaluria. After insertion of a covered EMS, fecaluria and contact-type dermatitis at perineal region subsequently improved. Three months later, fecaluria appeared again. Finally, seven months later, severe inflammation occurred at perineal and pubic region because of migration of the covered EMS into the bladder, then we removed the covered EMS and performed ileostomy. It is difficult to use the covered EMS treatment for benign rectovesical or rectovaginal fistula for a long term. (author)

    To study the prognostic impact of baby boomer (BB) generation on survival end-points of patients with early-stage endometrial carcinoma (EC). Data were obtained from the SEER registry between 1988-2009. Inclusion criteria included women who underwent hysterectomy for stage I-II EC. Patients were divided into two birth cohorts: BB (women born between 1946 and 1964) and pre-boomers (PB) (born between 1926 and 1945). A total of 30,956 patients were analyzed. Considering that women in the PB group were older than those of the BB generation, the statistical analysis was limited to women 50-59 years of age at the time of diagnosis (n=11,473). Baby boomers had a significantly higher percentage of endometrioid histology (pgeneration compared to the PB generation (p=0.0003) with a trend for improved uterine cancer-specific survival (p=0.0752). On multivariate analysis, birth cohort (BB vs. PB) was not a significant predictor of survival end-points. Factors predictive of survival included: tumor grade, FIGO stage, African-American race, and increased number of dissected LN. Our study suggests that the survival of BB women between 50-60 years of age is better compared to women in the PB generation. As more BB patients are diagnosed with EC, further research is warranted.

    To critically analyze the available evidence regarding the incidence, etiopathogenesis, and management of prostate cancer (CaP) in transgender women. In addition, this article aims to present a recent case report of a transgender woman with a unique presentation at the author's institution. An electronic nonsystematic literature search was performed to identify pertinent studies. PubMed search engine was queried by using the following search terms: "prostate cancer," "male to female transsexual," "transgender patient," "androgen + prostate cancer," "estrogen therapy + prostate cancer," and "health care barrier." In addition, a clinical case managed at our institution was reviewed and critically discussed. Including our case, there have been only 10 documented cases of CaP in transgender women. Additionally, an emerging body of literature has questioned the role of androgens in the development of CaP and suggested that estrogen therapy may not be as protective as initially thought. Therefore, the current evidence suggests that the transgender woman should be screened for CaP the same as a nontransgender men. Barriers to care in the transgender female population include accessing resources, medical knowledge deficits, ethics of transition-related medical care, diagnosing vs pathologizing transgender patients, financial restrictions of the patient, and health system determinants. Although rare, CaP in transgender women has been documented. Both the mechanism and the impact of receiving a bilateral orchiectomy on disease development are unclear. Future study is needed to examine these factors, and to further shape the treatment and screening regimen for these patients. Published by Elsevier Inc.

    To categorize the anatomic variants of uterine arteries, and determine the incidence of menopausal symptoms where the tubo-ovarian branches were seen prior to embolization. Between July 1997 and June 2000, 257 (n = 257) uterine fibroid embolizations were performed at our institution. Arteriograms were retrospectively evaluated. Uterine arteries were classified into groups: type I (the uterine artery as first branch of the inferior gluteal artery), type II (the uterine artery as second or third branch of the inferior gluteal artery), type III (the uterine artery, the inferior gluteal and the superior gluteal arteries arising as a trifurcation), type IV (the uterine artery as first branch of the hypogastric artery), inconclusive, or not studied. Tubo-ovarian branches were recorded if visualized prior to and/or after embolization. Menopausal symptoms were recorded (n = 175 at 3 months, n = 139 at 6 months, n = 98 at 1 year, n = 22 at 2 years) using written questionnaires. Five hundred and fourteen uterine arteries (n = 514) were evaluated. There were 38% classifiable types, 23% inconclusive, and 39% not studied. Classification was as follows: type I, 45%; type II, 6%; type III, 43%; type IV, 6%. Among 256 patients, tubo-ovarian arteries were seen in 36 prior to embolization, but not afterwards. In this group, 25 patients reported transient menopausal symptoms (hot flashes, amenorrhea). Five patients did not report any menopausal symptoms. Six patients did not answer the questionnaires. Type I is the most common type of anatomy, followed by type III. The tubo-ovarian arteries may be visualized prior to and/or after embolization. The embolization was monitored to avoid embolization of the tubo-ovarian branches. Menopausal symptoms were transient all patients when the tubo-ovarian branches were seen prior to embolization

    Outdoor air pollution may be associated with cancer risk at different sites. This study sought to investigate outdoor air pollution from waste gas emission effects on multiple cancer incidences in a retrospective population-based study in Shanghai, China. Trends in cancer incidence for males and females and trends in waste gas emissions for the total waste gas, industrial waste gas, other waste gas, SO 2 , and soot were investigated between 1983 and 2010 in Shanghai, China. Regression models after adjusting for confounding variables were constructed to estimate associations between waste gas emissions and multiple cancer incidences in the whole group and stratified by sex, Engel coefficient, life expectancy, and number of doctors per 10,000 populations to further explore whether changes of waste gas emissions were associated with multiple cancer incidences. More than 550,000 new cancer patients were enrolled and reviewed. Upward trends in multiple cancer incidences for males and females and in waste gas emissions were observed from 1983 to 2010 in Shanghai, China. Waste gas emissions came mainly from industrial waste gas. Waste gas emissions was significantly positively associated with cancer incidence of salivary gland, small intestine, colorectal, anus, gallbladder, thoracic organs, connective and soft tissue, prostate, kidney, bladder, thyroid, non-Hodgkin's lymphoma, lymphatic leukemia, myeloid leukemia, and other unspecified sites (all p emissions and the esophagus cancer incidence was observed (p emissions was associated with multiple cancer incidences.

    To explore lip cancer (LC) associations with work environmental exposures in a record-linkage study of Norwegian farmers. We hypothesize immunosuppressive substances (e.g. mycotoxins, pesticides) to influence LC incidence. A cohort of 131,243 male Norwegian farmers born 1925-1971 was established by cross-linkage of national registers and followed up through 1999 for incident LC, (ICD-7 site 140) in the Cancer Registry of Norway. Farm production data from agricultural censuses 1969-1979 and meteorological data on solar radiation and fungal forecasts (events of wet and temperate conditions known to favour fungal growth and mycotoxin formation) served as exposure proxies. Adjusted rate ratios (RR) and 95% confidence intervals (CI) were estimated using Poisson regression. We identified 108 LC cases (rate 4.4 per 100,000 person-years). We found LC to be moderately associated with horses on the farm (RR = 1.6, CI = 1.0-2.4), construction work employment (RR = 1.7, CI = 1.1-2.6), pesticide use (RR = 0.7, CI = 0.4-1.0), grain production (RR = 1.3, CI = 0.9-2.1) and increasing levels of fungal forecasts (RR = 1.6, CI = 0.9-2.8 in the highest two quartiles). Moderate associations of LC with grain production and fungal forecasts and the negative association with pesticide could possibly be explained by exposure to immunosuppressive mycotoxins. Some of the associations observed could be explained by solar exposure. Copyright 2004 Kluwer Academic Publishers

    To evaluate feasibility and preliminary outcomes associated with sequential whole abdomen irradiation (WAI) as consolidative treatment following comprehensive surgery and systemic chemotherapy for advanced endometrial cancer. We conducted a retrospective analysis of patients treated at our institution from 2000 to 2011. Inclusion criteria were stage III-IV endometrial cancer patients with histological proof of one or more sites of extra-uterine abdomen-confined disease, treated with WAI as part of multimodal therapy. Endpoints were feasibility, acute toxicity, late effects, recurrence-free survival (RFS) and overall survival (OS). Twenty patients were identified. Chemotherapy consisted of 3 to 6 cycles of a platinum-paclitaxel regimen in 18 patients. WAI was delivered using conventional technique to a median total dose of 27.5 Gy. No grade 4 toxicities occurred during chemotherapy or radiotherapy. No radiation dose reduction was necessary. Three patients developed small bowel obstruction, all in the context of recurrent intraperitoneal disease. Kaplan-Meier estimates and 95% confidence intervals for RFS and OS at one year were 63% (38–80%) and 83% (56-94%) and at 3 years 57% (33-76%) and 62% (34-81%), respectively. On univariate Cox analysis, stage IVB and serous papillary (SP) histology were found to be statistically significantly (at the p = 0.05 level) associated with worse RFS and OS. The peritoneal cavity was the most frequent site of initial failure. Consolidative WAI following chemotherapy is feasible and can be performed without interruption with manageable acute and late toxicity. Patients with endometrioid adenocarcinoma, especially stage FIGO III, had favorable outcomes possibly meriting prospective evaluation of the addition of WAI following chemotherapy in selected patients. Patients with SP do poorly and do not routinely benefit from this approach

    Background: In clinical cancer research of morbidity, low associations between clinician-assessed toxicity/morbidity and patient-reported symptoms are consistently described in the literature. While morbidity grading systems are supposed to follow more or less objective criteria, patient reported symptoms inherently are based on a subjective self-evaluation of the impact on quality of life. The aim of this study was to focus on major discrepancies with high clinical relevance and to evaluate its impact with regard to underreporting of morbidity. Material and methods: Early morbidity assessed by clinicians with CTCAEv.3 and patient reported quality of life (EORTC-QLQ-C30/CX24) were compared regarding 12 overlapping symptoms in 223 patients with uterine cervical cancer 3 months after definitive radio(chemo)therapy in the ongoing EMBRACE study. Mismatches showing discrepancies between both grading systems were classified, if patients reported substantial symptoms (quite a bit/very much) and CTCAE grading was rated G0. Results: In total, 360 substantial symptoms were reported by patients by EORTC-QLQ; 159 (44%) of those were not recognized by CTCAE. Symptoms with the highest occurrence of mismatches overall are urinary frequency, fatigue, and insomnia. Large institutional differences were found, showing two centers with 4 vs. 71% of patients with at least one mismatch. Conclusion: Analysis of mismatches indicated a high risk of underestimation of early morbidity. Thus, nearly half of the patient-reported substantial symptoms were not recognized by CTCAE scoring (G0) 3 months after treatment. Prospective assessment of morbidity in clinical studies should, therefore, integrate patient reported symptoms to receive a complete and comprehensive picture. (orig.)

    Human testicular germ cell tumors (TGCT) have a strong genetic component and a high familial relative risk. However, linkage analyses have not identified a rare, highly penetrant familial TGCT (FTGCT) susceptibility locus. Currently, multiple low-penetrance genes are hypothesized to underlie the familial multiple-case phenotype. The observation that two is the most common number of affected individuals per family presents an impediment to FTGCT gene discovery. Clinically, the prospective TGCT risk in the multiple-case family context is unknown. We performed a prospective analysis of TGCT incidence in a cohort of multiple-affected-person families and sporadic-bilateral-case families; 1,260 men from 140 families (10,207 person-years of follow-up) met our inclusion criteria. Age-, gender-, and calendar time-specific standardized incidence ratios (SIR) for TGCT relative to the general population were calculated using SEER*Stat. Eight incident TGCTs occurred during prospective FTGCT cohort follow-up (versus 0.67 expected; SIR = 11.9; 95% CI, 5.1-23.4; excess absolute risk = 7.2/10,000). We demonstrate that the incidence rate of TGCT is greater among bloodline male relatives from multiple-case testicular cancer families than that expected in the general population, a pattern characteristic of adult-onset Mendelian cancer susceptibility disorders. Two of these incident TGCTs occurred in relatives of sporadic-bilateral cases (0.15 expected; SIR = 13.4; 95% CI, 1.6-48.6). Our data are the first to indicate that despite relatively low numbers of affected individuals per family, members of both multiple-affected-person FTGCT families and sporadic-bilateral TGCT families comprise high-risk groups for incident testicular cancer. Men at high TGCT risk might benefit from tailored risk stratification and surveillance strategies. ©2015 American Association for Cancer Research.

    Colon cancers are thought to be an inevitable result of aging, while testicular cancers are thought to develop in only a small fraction of men, beginning in utero. These models of carcinogenesis are, in part, based upon age-specific incidence data. The specific incidence for colon cancer appears to monotonically increase with age, while that of testicular cancer increases to a maximum value at about 35 years of age, then declines to nearly zero by the age of 80. We hypothesized that the age-specific incidence for these two cancers is similar; the apparent difference is caused by a longer development time for colon cancer and the lack of age-specific incidence data for people over 84 years of age. Here we show that a single distribution can describe the age-specific incidence of both colon carcinoma and testicular cancer. Furthermore, this distribution predicts that the specific incidence of colon cancer should reach a maximum at about age 90 and then decrease. Data on the incidence of colon carcinoma for women aged 85-99, acquired from SEER and the US Census, is consistent with this prediction. We conclude that the age specific data for testicular cancers and colon cancers is similar, suggesting that the underlying process leading to the development of these two forms of cancer may be similar.

    Different rate of development of productive infections (as low grade cervical intraepithelial neoplasias), or high grade lesions and cervical malignant tumors associated with infections of the Transformation zone (TZ) by High-Risk Human Papillomavirus (HR-HPV), could suggest that different epithelial host target cells could exist. If there is more than one target cell, their differential infection by HR-HPV may play a central role in the development of cervical cancer. Recently, the concept that cancer might arise from a rare population of cells with stem cell-like properties has received support in several solid tumors, including cervical cancer (CC). According to the cancer stem cell (CSC) hypothesis, CC can now be considered a disease in which stem cells of the TZ are converted to cervical cancer stem cells by the interplay between HR-HPV viral oncogenes and cellular alterations that are thought to be finally responsible for tumor initiation and maintenance. Current studies of CSC could provide novel insights regarding tumor initiation and progression, their relation with viral proteins and interplay with the tumor micro-environment. This review will focus on the biology of cervical cancer stem cells, which might contribute to our understanding of the mechanisms responsible for cervical tumor development. PMID:23341858

    Among different populations, the shape of the age-incidence curve for breast cancer is strongly related to the overall incidence of breast cancer in the respective population. Data are available from Iceland for the period 1911--1972. These data show that breast cancer has increased very markedly in Iceland during this period, and that as the overall incidence has risen, so the age-incidence curve has changed in shape, the relation between the shape and the overall incidence being the same as that now observed in other countries. The change in shape is shown to be explicable entirely as a cohort phenomenon, each decade of birth cohort having an age-incidence curve of similar shape, but with different overall incidence. Data from some other regions of the world indicate that many of the present differences in the shape of the age-incidence curve may be the reflection of cohort phenomena.

    To describe the sex-specific incidence rates and the male-to-female incidence-rate ratios (IRRs) of different cancer types, and to explore the corresponding sex disparities in an area of Eastern China. We used data from the Cancer Registry in Jiashan County, and calculated the sex-specific age-standardized (2010 China standard population) incidence rates and the male-to-female IRRs for different cancer types during the period 1995-2014. The age-standardized incidence rates of all cancers for the whole period 1995-2014 were 151.48 per 100,000 person-years for males and 83.75 per 100,000 person-years for females, and the corresponding male-to-female IRR was 1.81 (95% confidence interval: 1.77-1.85). Specifically, males presented higher incidences in most types of cancer with the exceptions of cancers of connective and other soft tissues, gallbladder (including extrahepatic bile ducts), and thyroid gland. In addition, the age-specific incidences of the ten most common cancers in males were higher than those in females in most age groups. Our results reveal a male predominance in incidence for a majority of cancers in Jiashan County, Eastern China. Possible explanations for these sex disparities in cancer incidence may include lifestyle factors, particularly smoking. Copyright © 2017. Published by Elsevier Ltd.

    The determination of radiosensitiveness based on 111 operated specimens after test irradiation of 1000R was compared with that based on 64 specimens which had received biopsies seven days after irradiation. It was concluded that the determination of radiosensitiveness by local biopsy could be applied to practical use. The results of this study are listed as follows: (1) Radiosensitivity exists within tumor cells themselves before irradiation, while radiosensitiveness is a complicated change in which some reaction on the host side added to degenerated tumor cells. (2) In the determination of radio-sensitiveness, there was a good accordance of 85% between biopsies and removed specimens. (3) The followings are findings of favorable radiosensitiveness based on the removed specimens; (a) neutrocyte infiltration within cancer nests, (b) lysis of cancer nests, (c) destruction of fundus of cancer nests, (d) damages of advanced sites of cancer infiltration, (e) damages of chromatin. As unfavorable findings, (f) mitosis, (g) abundant viable cells. (4) Various histological findings within cancer nests and variation of radiosensitiveness according to various regions of the tumor often cause a discord with biopsies. (5) Many specimens which show the intermediate histological type in maturation before irradiation indicate favorable radiosensitiveness. Even if they belong to the intermediate type, the specimens in which the issued histological findings are mixed show mostly unfavorable radiosensitiveness. (6) Removed specimens can be expressed in indices of radiosensitiveness. (Ichikawa, K.)

    A case of radiation keratosis, regarded as the precancercerous state of the skin, is reported. A 54-year-old woman with cervical cancer was treated by postoperative sieve radiotherapy with 6,000 R as the tumor dose. Although free from cervical cancer, 10 years after this irradiation treatment, she was found to manifest multiple radiation keratosis coinciding with the pores of the sieve. We suggest that patients treated by irradiation for malignant diseases must be carefully followed for long periods, attending to not only the recurrence of the primary disease but also to radioinduced malignancy.

    Objective: To estimate the cancer incidence and mortality in elderly Chinese population in 2013 based on the data from local cancer registries submitted to National Central Cancer Registry (NCCR). Methods: Data from 255 cancer registries submitted to NCCR with qualified data after checked and evaluated, were selected for this estimation. Cancer incidence and mortality were stratified by areas, sex, age groups and cancer site, combined with population data of the year 2013 to estimate cancer epidemiology in older people in China. Chinese population census in 2000 and Segi's population were used for the estimation of age-standardized incidence/mortality rates. Results: All the 255 cancer registries (88 in urban and 167 in rural areas) were selected for this estimation, covered 37 407 728 elderly subjects, accounting for 17.73% of the entire national elderly population. It was estimated about 2 171.0 thousand new cancer cases in older people in China, accounting for 58.96% of all cancer incidence, with the crude incidence rate of 1 029.16/100 000 (1 297.96 per 100 000 in male, 777.18 per 100 000 in female), and the age-standardized incidence rate by Chinese standard population (ASIRC, 2000) was 1 019.25 per 100 000. It was estimated about 1 600.5 thousand deaths in older people in China, accounting for 67.70% of all cancer deaths, with the crude mortality of 758.72/100 000 (988.37 per 100 000 in males, 543.44 per 100 000 in females), and the age-standardized incidence rate by Chinese standard population (ASIRC, 2000) was 730.78 per 100 000. Lung cancer, stomach cancer, colorectal cancer, liver cancer and esophageal cancer were the most common cancers, accounting for about 67.70% of all cancer cases in China. Those cancers are also the most common cancers in China, accounting for about 73.45% of all cancer deaths. Conclusions: The cancer burden of elderly population in China is very serious. The major cancer incidence and mortality in urban and rural areas are similar

    Full Text Available Background and objective The aim of this study is to analyze lung cancer epidemiological trend and estimate lung cancer burden in China. Methods Lung cancer age specific mortality and incidence rate ratios in different areas and sexes were obtained from national cancer registration database in 2004 and 2005. Cancer crude mortalities were retrieved from the database of the third national death survey, 2004-2005. Age specific incidence rates of lung cancer were calculated using mortality and M/I ratios. Annual percent change (APC was estimated by log regression model using Joint Point software by analyzing pooled lung cancer incidence data from 10 cancer registries from 1988 to 2005. Results The total estimated new cases and deaths of lung cancer in 2005 were 536 407 and 475 768 which were higher in male than in female. There was 1.63% increase of lung cancer incidence per year from 1988 to 2005, however, the trend showed a slowdown by 0.55% annually after adjusted by age. Conclusion Lung cancer is one of major health issues in China and the burden is getting serious. Ageing population is main cause for increasing incidence and mortality of lung cancer. Effective cancer prevention and control is imperative. Especially, tobacco control should be carried out in statewide.

    Dietary energy density (ED) is a measure of diet quality that estimates the amount of energy per unit of food (kilocalories per gram) consumed. Low-ED diets are generally high in fiber and fruits and vegetables and low in fat. Dietary ED has been positively associated with body mass index (BMI) and other risk factors for postmenopausal breast cancer. We evaluated the associations of total dietary ED and energy-dense (high-ED) foods with postmenopausal breast cancer incidence. Analyses included 56,795 postmenopausal women from the Cancer Prevention Study II Nutrition Cohort with no previous history of breast or other cancers and who provided information on diet, lifestyle, and medical history in 1999. Multivariable-adjusted breast cancer incidence rate ratios (RRs and 95% CIs) were estimated for quintiles of total dietary ED and for the consumption of high-ED foods in Cox proportional hazards regression models. During a median follow-up of 11.7 y, 2509 invasive breast cancer cases were identified, including 1857 estrogen receptor-positive and 277 estrogen receptor-negative tumors. Median dietary ED was 1.5 kcal/g (IQR: 1.3-1.7 kcal/g). After adjusting for age, race, education, reproductive characteristics, and family history, high compared with low dietary ED was associated with a statistically significantly higher risk of breast cancer (RR for fifth quintile compared with first quintile: 1.20; 95% CI: 1.05, 1.36; P-trend = 0.03). The association between the amount of high-ED foods consumed and breast cancer risk was not statistically significant. We observed no differences by estrogen receptor status or effect modification by BMI, age, or physical activity. These results suggest a modest positive association between total dietary ED and risk of postmenopausal breast cancer. © 2016 American Society for Nutrition.

    Cancer incidence and mortality rates in the US are declining, but this decrease may not be observed in rural areas where residents are more likely to live in poverty, smoke, and forego cancer screening. However, there is limited research exploring national rural-urban differences in cancer incidence and trends. We analyzed data from the North American Association of Central Cancer Registries' public use dataset, which includes population-based cancer incidence data from 46 states. We calculated age-adjusted incidence rates, rate ratios, and annual percentage change (APC) for: all cancers combined; selected individual cancers; and cancers associated with tobacco use and human papillomavirus (HPV). Rural-urban comparisons were made by demographic, geographic, and socioeconomic characteristics for 2009 to 2013. Trends were analyzed for 1995 to 2013. Combined cancers incidence rates were generally higher in urban populations, except for the South, though the urban decline in incidence rate was greater than in rural populations (10.2% vs. 4.8%, respectively). Rural cancer disparities included higher rates of tobacco associated, HPV associated, lung and bronchus, cervical , and colorectal cancers across most population groups. Further, HPV-associated cancer incidence rates increased in rural areas (APC=0.724, purban areas. Cancer rates associated with modifiable risks - tobacco, HPV, and some preventive screening modalities (e.g. colorectal and cervical cancers) - were higher in rural compared to urban populations. Population-based, clinical, and/or policy strategies and interventions that address these modifiable risk factors could help reduce cancer disparities experienced in rural populations.

    Background Human testicular germ cell tumors (TGCT) have a strong genetic component and a high familial relative risk. However, linkage analyses have not identified a rare, highly-penetrant familial TGCT (FTGCT) susceptibility locus. Currently, multiple low-penetrance genes are hypothesized to underlie the familial multiple-case phenotype. The observation that two is the most common number of affected individuals per family presents an impediment to FTGCT gene discovery. Clinically, the prospective TGCT risk in the multiple-case family context is unknown. Methods We performed a prospective analysis of TGCT incidence in a cohort of multiple-affected-person families and sporadic-bilateral-case families; 1,260 men from 140 families (10,207 person-years of follow-up) met our inclusion criteria. Age-, gender-, and calendar time-specific standardized incidence ratios (SIR) for TGCT relative to the general population were calculated using SEER*Stat. Results Eight incident TGCTs occurred during prospective FTGCT cohort follow-up (versus 0.67 expected; SIR=11.9; 95% confidence interval [CI]=5.1–23.4; excess absolute risk=7.2/10,000). We demonstrate that the incidence rate of TGCT is greater among bloodline male relatives from multiple-case testicular cancer families than that expected in the general population, a pattern characteristic of adult-onset Mendelian cancer susceptibility disorders. Two of these incident TGCTs occurred in relatives of sporadic-bilateral cases (0.15 expected; SIR=13.4; 95%CI=1.6–48.6). Conclusions Our data are the first indicating that despite relatively low numbers of affected individuals per family, members of both multiple-affected-person FTGCT families and sporadic-bilateral TGCT families comprise high-risk groups for incident testicular cancer. Impact Men at high TGCT risk might benefit from tailored risk stratification and surveillance strategies. PMID:26265202

    Sirolimus, an immunosuppressant option for kidney transplant recipients, may reduce cancer risk by interrupting the mammalian target of rapamycin pathway. However, studies of sirolimus and cancer incidence in kidney recipients have not been definitive, and have had limited ability to examine specific cancer types. The literature was systematically reviewed to identify randomized controlled trials (RCTs) and observational studies of kidney recipients that compared sirolimus users to sirolimus nonusers. Meta-analytic methods were used to obtain pooled estimates of the association between sirolimus use and incidence of total cancer and specific cancer types. Estimates were stratified by study type (RCT vs. observational) and use of cyclosporine (an immunosuppressant that affects DNA repair). Twenty RCTs and two observational studies were eligible for meta-analysis, including 39,039 kidney recipients overall. Sirolimus use was associated with lower overall cancer incidence (incidence rate ratio [IRR] = 0.71, 95% CI = 0.56-0.90), driven by a reduction in incidence of nonmelanoma skin cancer (NMSC, IRR = 0.49, 95% CI = 0.32-0.76). The protective effect of sirolimus on NMSC risk was most notable in studies comparing sirolimus against cyclosporine (IRR = 0.19, 95% CI = 0.04-0.84). After excluding NMSCs, there was no overall association between sirolimus and incidence of other cancers (IRR = 1.06, 95% CI = 0.69-1.63). However, sirolimus use had associations with lower kidney cancer incidence (IRR = 0.40, 95% CI = 0.20-0.81), and higher prostate cancer incidence (IRR = 1.85, 95% CI = 1.17-2.91). Among kidney recipients, sirolimus users have lower NMSC risk, which may be partly due to removal of cyclosporine. Sirolimus may also reduce kidney cancer risk but did not appear protective for other cancers, and it may actually increase prostate cancer risk. © 2015 The Authors.

    Among patients with ESRD, cancer risk is affected by kidney dysfunction and by immunosuppression after transplant. Assessing patterns across periods of dialysis and kidney transplantation may inform cancer etiology. We evaluated 202,195 kidney transplant candidates and recipients from a linkage between the Scientific Registry of Transplant Recipients and cancer registries, and compared incidence in kidney function intervals (time with a transplant) with incidence in nonfunction intervals (waitlist or time after transplant failure), adjusting for demographic factors. Incidence of infection-related and immune-related cancer was higher during kidney function intervals than during nonfunction intervals. Incidence was most elevated for Kaposi sarcoma (hazard ratio [HR], 9.1; 95% confidence interval (95% CI), 4.7 to 18), non-Hodgkin's lymphoma (HR, 3.2; 95% CI, 2.8 to 3.7), Hodgkin's lymphoma (HR, 3.0; 95% CI, 1.7 to 5.3), lip cancer (HR, 3.4; 95% CI, 2.0 to 6.0), and nonepithelial skin cancers (HR, 3.8; 95% CI, 2.5 to 5.8). Conversely, ESRD-related cancer incidence was lower during kidney function intervals (kidney cancer: HR, 0.8; 95% CI, 0.7 to 0.8 and thyroid cancer: HR, 0.7; 95% CI, 0.6 to 0.8). With each successive interval, incidence changed in alternating directions for non-Hodgkin's lymphoma, melanoma, and lung, pancreatic, and nonepithelial skin cancers (higher during function intervals), and kidney and thyroid cancers (higher during nonfunction intervals). For many cancers, incidence remained higher than in the general population across all intervals. These data indicate strong short-term effects of kidney dysfunction and immunosuppression on cancer incidence in patients with ESRD, suggesting a need for persistent cancer screening and prevention.

    The aim of our study was to investigate and evaluate the prognostic value of and correlations between preclinical and clinical factors such as the stage of the disease, blood Hb level before treatment, size of cervix and lymph nodes evaluated by CT, age, dose of irradiation and duration of radiotherapy related to overall survival, disease-free survival, local control and metastases-free survival in cervical cancer patients receiving radiotherapy alone. 162 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIA-IIIB cervical carcinoma treated with irradiation were analysed. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. The Hb level before treatment showed significant influence on overall survival (p = 0.001), desease free survival (p = 0.040) and local control (p = 0.038). The lymph node status (>10 mm) assessed on CT had impact on overall survival (p = 0,030) and local control (p = 0,036). The dose at point A had impact on disease free survival (p = 0,028) and local control (p = 0,021) and the radiotherapy duration had showed significant influence on overall survival (p = 0,045), disease free survival (p = 0,006) and local control (p = 0,033). Anemia is a significant and independent prognostic factor of overall survival, disease-free survival and local control in cervical cancer patients treated with irradiation. The size of lymph nodes in CT is an independent prognostic factor for overall survival and local control in cervical cancer patients. The size of cervix uteri evaluated by CT has no prognostic significance in cervical cancer patients treated with radiotherapy. The prognostic value of FIGO stage of cervical cancer is influenced by other factors, analyzed in this study and is not an independent prognostic factor

    Lung cancer is the deadliest cancer worldwide and the most common cancer in Asia. It is necessary to get information on epidemiology and inequalities related to incidence and mortality of the cancer to use for planning and further research. This study aimed to investigate epidemiology and inequality of incidence and mortality from lung cancer in Asia. The study was conducted based on data from the world data of cancer and the World Bank [including the Human Development Index (HDI) and its components]. The incidence and mortality rates, and cancer distribution maps were drawn for Asian countries. To analyze data, correlation test between incidence and death rates, and HDI and its components at significant was used in the significant level of 0.05 using SPSS software. A total of 1,033,881 incidence (71.13% were males and 28.87% were females. Sex ratio was 2.46) and 936,051 death (71.45% in men and 28.55% in women. The sex ratio was 2.50) recorded in Asian countries in 2012. Five countries with the highest standardized incidence and mortality rates of lung cancer were Democratic Republic of Korea, China, Armenia, Turkey, and Timor-Leste, respectively. Correlation between HDI and standardized incidence rate was 0.345 (P=0.019), in men 0.301 (P=0.042) and in women 0.3 (P=0.043); also between HDI and standardized mortality rate 0.289 (P=0.052), in men 0.265 (P=0.075) and in women 0.200 (P=0.182). The incidence of lung cancer has been increasing in Asia. It is high in men. Along with development, the incidence and mortality from lung cancer increases. It seems necessary to study reasons and factors of increasing the incidence and mortality of lung cancer in Asian countries.

    The expression of receptor-binding cancer antigen expressed on SiSo cells (RCAS1) is related significantly to the overall survival of patients with various cancers. RCAS1 reportedly induces apoptotic cell death in peripheral lymphocytes, which may contribute to the escape of tumor cells from immune surveillance. RCAS1 expression also has been related to tumor invasiveness and size in uterine cervical cancer. To clarify whether RCAS1 exacerbates tumor progression, the authors investigated the association between RCAS1 expression and tumor growth potential. The authors constructed small interfering ribonucleic acid (RNA) (siRNA) to target RCAS1. After transfection of siRNA and the RCAS1-encoding gene, growth of tumor cells was assessed in vitro and in vivo. The correlation between RCAS1 expression and angiogenesis was investigated in the transfected cells and in inoculated tumors from nude mice. In addition, the same association was investigated immunohistochemically with tissue samples from patients with uterine cervical cancer. Knockdown of RCAS1 expression by siRNA significantly suppressed the in vivo growth of SiSo and HOUA tumor cells (P cell growth was not affected significantly. Enhanced RCAS1 expression significantly promoted in vivo growth, but not in vitro growth, of tumors derived from COS-7 cells (P = .0039). Introduction of the RCAS1-encoding gene increased expression of vascular endothelial growth factor (VEGF). In uterine cervical cancer, RCAS1 expression was associated significantly with VEGF expression (P = .0407) and with microvessel density (P = .0108). RCAS1 may be a pivotal regulator of tumor growth through angiogenesis. Continued exploration of the biologic function of RCAS1 may allow the development of novel therapeutic strategies for uterine cancer.

    Full Text Available Abstract Background It has been hypothesised that increased VEGF-D expression may be an independent prognostic factor for endometrial cancer progression and lymph node metastasis; however, the mechanism by which VEGF-D may promote disease progression in women with endometrial cancer has not been investigated. Our aim was to describe the distribution of lymphatic vessels in mouse uterus and to examine the effect of VEGF-D over-expression on these vessels in a model of endometrial cancer. We hypothesised that VEGF-D over-expression would stimulate growth of new lymphatic vessels into the endometrium, thereby contributing to cancer progression. Methods We initially described the distribution of lymphatic vessels (Lyve-1, podoplanin, VEGFR-3 and VEGF-D expression in the mouse uterus during the estrous cycle, early pregnancy and in response to estradiol-17beta and progesterone using immunohistochemistry. We also examined the effects of VEGF-D over-expression on uterine vasculature by inoculating uterine horns in NOD SCID mice with control or VEGF-D-expressing 293EBNA tumor cells. Results Lymphatic vessels positive for the lymphatic endothelial cell markers Lyve-1, podoplanin and VEGFR-3 profiles were largely restricted to the connective tissue between the myometrial circular and longitudinal muscle layers; very few lymphatic vessel profiles were observed in the endometrium. VEGF-D immunostaining was present in all uterine compartments (epithelium, stroma, myometrium, although expression was generally low. VEGF-D immunoexpression was slightly but significantly higher in estrus relative to diestrus; and in estradiol-17beta treated mice relative to vehicle or progesterone treated mice. The presence of VEGF-D over-expressing tumor cells did not induce endometrial lymphangiogenesis, although changes were observed in existing vessel profiles. For myometrial lymphatic and endometrial blood vessels, the percentage of profiles containing proliferating

    Testicular cancer is one of the most common cancers among young men between ages 20-34 in countries with high or very high levels of the Human Development Index (HDI). This study investigated the incidence and mortality of prostate cancer and the relationship with the HDI and its dimensions in Asia in 2012. The study was conducted based on data from the world data of cancer and the World Bank (including the HDI and its components). Standardized incidence and mortality rates of testicular cancer were calculated for Asian countries. Correlations between incidence and/ormortality rates, and the HDI and its components were assessed with the use of the correlation test, using SPSS software. There was a total of 14902 incidences and 5832 death were recorded in Asian countries in 2012. Among the Asian countries, the five countries with the highest standardized incidence rates of testicular cancer were Israel, Georgia, Turkey, Lebanon and Kazakhstan and the five countries with the highest standardized mortality rates were Turkey, Georgia, Jordan, Cambodia and the Syrian Arab Republic. A positive correlation of 0.382 was observed between the standardized incidence rates of testicular cancer and the HDI (p=0.009). Also a negative correlation of 0.298 between the standardized mortality rate of testicular cancer and the Human Development Index was noted although this relation was statistically non-significant (p=0.052). There is a positive correlation between HDI and the standardized incidence rate of testicular cancer and negative correlation with standardized mortality rate.

    Cancer Incidence in Five Continents (CI5), a longstanding collaboration between the International Agency for Research on Cancer and the International Association of Cancer Registries, serves as a unique source of cancer incidence data from high-quality population-based cancer registries around the world. The recent publication of Volume X comprises cancer incidence data from 290 registries covering 424 populations in 68 countries for the registration period 2003-2007. In this article, we assess the status of population-based cancer registries worldwide, describe the techniques used in CI5 to evaluate their quality and highlight the notable variation in the incidence rates of selected cancers contained within Volume X of CI5. We also discuss the Global Initiative for Cancer Registry Development as an international partnership that aims to reduce the disparities in availability of cancer incidence data for cancer control action, particularly in economically transitioning countries, already experiencing a rapid rise in the number of cancer patients annually. © 2015 UICC.

    A series of studies were performed to evaluate the oncogenic potential of inactivated herpes simplex viruses types 1 (HSV-1) and 2 (HSV-2) in the mouse cervix. HSV-1 or HSV-2 prepared in HEp-2 cell cultures and inactivated by exposure to formalin or ultraviolet light was applied to the mouse cervix for periods ranging from 20 to 90 weeks. Control mice were exposed for the same period to control fluids. Vaginal cytologic preparations from all animals were examined weekly to detect epithelial abnormalities. Animals were sacrificed and histopathological studies were carried out when cellular changes seen on vaginal smears resembled those indicative of premalignant or malignant changes as previously established in a similar model system using coal tar hydrocarbons. Other animals were exposed for periods up to 90 weeks, or until there was cellular evidence of invasive cancer. Cytologic and histologic materials were coded and evaluated without knowledge of whether they were from virus-exposed or control animals. Premalignant and malignant cervical lesions similar to those that occur in women were encountered in 78 to 90% of the virus-exposed animals. All controls were normal. Invasive cancer was detected in 24 to 60% of the animals and dysplasia was found in 18 to 66%. The yield of invasive cancer was twice as great after exposure to ultraviolet-inactivated HSV-2 as compared with formalin-inactivated virus. Various histologic grades of carcinoma of the cervix and endometrium were found. No primary lesions were found in the vagina or ovaries

    Background Population-based epidemiologic studies about colorectal cancer are lacking in China. This study aims to provide a basis for colorectal cancer screening and prevention, through analysis and comparisons the characteristics of the trends in colorectal cancer incidence in Beijing and selected representative regions. RESULTS The annual incidence rate in Beijing region increased significantly, from 9.40/100,000 in 1998 to 18.61/100,000 in 2012. The stratified rate showed that the incidence of distal colon adenocarcinoma increased substantially in men, especially in those aged > 75 years and residing in urban areas. Although the incidence rate in Beijing is still lower than in Shanghai, Jiashan, and Hong Kong in China, it is increasing rapidly. Further, the incidence rate in Beijing is lower than in New York, Oxford and Osaka, but higher than in Mumbai and Kyadondo. The incidence trend in Beijing is increasing especially in older groups, while in other regions such as New York, it is decreasing in these age groups. Materials and Methods Colorectal cancer incidence data were obtained from Beijing Cancer Registry and Cancer Incidence in Five Continents Plus database. All incidence rates were age-standardized according to Segi's world population. Incidence trends were characterized by calculating the annual percent changes using the Joinpoint Regression Program. Conclusions Compared with other regions, Beijing has a medium level of colorectal cancer incidence, however, it is increasing significantly. There are obvious differences in the cancer subsite, sex and age distributions between Beijing and other regions. Prevention and screening of colorectal cancer in Beijing should be strengthened.

    Background Breast cancer is estimated to be the most common cancer worldwide. We sought to assemble publicly available data from Africa to provide estimates of the incidence of breast cancer on the continent. Methods A systematic search of Medline, EMBASE, Global Health and African Journals Online (AJOL) was conducted. We included population- or hospital-based registry studies on breast cancer conducted in Africa, and providing estimates of the crude incidence of breast cancer among women. A random effects meta-analysis was employed to determine the pooled incidence of breast cancer across studies. Results The literature search returned 4648 records, with 41 studies conducted across 54 study sites in 22 African countries selected. We observed important variations in reported cancer incidence between population- and hospital-based cancer registries. The overall pooled crude incidence of breast cancer from population-based registries was 24.5 per 100 000 person years (95% confidence interval (CI) 20.1-28.9). The incidence in North Africa was higher at 29.3 per 100 000 (95% CI 20.0-38.7) than Sub-Saharan Africa (SSA) at 22.4 per 100 000 (95% CI 17.2-28.0). In hospital-based registries, the overall pooled crude incidence rate was estimated at 23.6 per 100 000 (95% CI 18.5-28.7). SSA and Northern Africa had relatively comparable rates at 24.0 per 100 000 (95% CI 17.5-30.4) and 23.2 per 100 000 (95% CI 6.6-39.7), respectively. Across both registries, incidence rates increased considerably between 2000 and 2015. Conclusions The available evidence suggests a growing incidence of breast cancer in Africa. The representativeness of these estimates is uncertain due to the paucity of data in several countries and calendar years, as well as inconsistency in data collation and quality across existing cancer registries.

Conclui-se que a queda da mortalidade por câncer do útero não especificado sinaliza uma melhora na precisão do diagnóstico clínico e na qualidade do preenchimento do atestado de óbito, e indica aumento de cobertura do teste de Papanicolaou.Uterine cervical cancer shows a higher incidence in some Brazilian cities. It is a common cause of death in women from developing countries, despite the longstanding availability of an effective screening test, the Pap smear. This study aimed to evaluate the temporal trends of crude, age-adjusted, and age-specific mortality rates from cervical cancer, endometrial cancer, and cancer of the uterus not otherwise specified (NOS in the city of São Paulo from 1980 to 1999. Results showed a slight reduction in cervical cancer rates, a decrease in NOS uterine cancer rates, and an increase in endometrial cancer mortality rates. The fall in mortality from NOS uterine cancer indicates an improvement in diagnostic accuracy and quality of information on death certificates and may point to an increase in coverage of cervical cancer screening using the Pap smear.

    Original data reported a potential increased incidence of thyroid cancer surrounding the Three Mile Island (TMI) nuclear facility. A causal link to the accident, however, was indeterminate. Our objective was to determine if data 30 years later will change original conclusions, explore thyroid cancer incidence rates near nuclear power plants, and better understand effects of chronic low level radiation. Retrospective cross-sectional study. Retrospective data for specific Pennsylvania counties were provided by the Pennsylvania Cancer Registry Dataset for thyroid cancer using the Epidemiological Query and Mapping System search engine. Our study examines thyroid cancer incidence from 1985 through 2009 analyzed by year, county, and age. Thirty years after the TMI accident, an increased incidence of thyroid cancer is seen in counties south of TMI and in high-risk age groups. The average incidence rates from 1990 through 2009 were greater than expected in York, Lancaster, Adams, and Chester Counties. Thyroid cancer incidence since the TMI accident was greater than expected in the counties analyzed when compared to local and national population growth. This supports a link to chronic low level radiation exposure and thyroid cancer development. Despite these findings, a direct correlation to the accident remains uncertain as incidence rates may coincide with other factors, and original data were limited. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    Subjects were residents older than 30 years ascertained through the population-based cancer registry in Nagasaki City during a ten-year period from 1973 to 1982. The total number of cancer patients was 6,243 (3,456 men and 2,787 women), 2,626 of whom were A-bomb survivors. Stomach cancer was the most common, irrespective of sex, in both exposed and non-exposed groups. Crude incidence of cancer of any organ was higher in the exposed group, especially the group of people entering the city early after the bombing, than the non-exposed group. In the groups exposed at <2,000 m and at 2,000 - 10,000 m from the hypocenter, the incidence of stomach, lung, and thyroid cancers and malignant lymphoma; and the incidence of stomach, breast, and thyroid cancers were radiation-dose dependent in men and women, respectively. Age-adjusted relative risks of breast and thyroid cancers were significantly higher in the exposed group of women than the non-exposed group. Comparing cancer incidence during the first and latter five years, the incidence of thyroid cancer and malignant lymphoma tended to decrease or remain unchanged in both men and women. The incidence of colorectal cancer showed a tendency to increase. An increased incidence of stomach and lung cancers was restricted to the exposed group of women. As for breast cancer, the exposed group of women had a tendency for decrease, as opposed to the non-exposed group with the increased incidence. There was no significant difference in histologic types between the exposed and non-exposed groups. (Namekawa, K.)

    Administrative databases are increasingly being used in cancer observational studies. Identifying incident cancer in these databases is crucial. This study aimed to develop algorithms to estimate cancer incidence by using health administrative databases and to examine the accuracy of the algorithms in terms of national cancer incidence rates estimated from registries. We identified a cohort of 463 033 participants on 1 January 2012 in the Echantillon Généraliste des Bénéficiaires (EGB; a representative sample of the French healthcare insurance system). The EGB contains data on long-term chronic disease (LTD) status, reimbursed outpatient treatments and procedures, and hospitalizations (including discharge diagnoses, and costly medical procedures and drugs). After excluding cases of prevalent cancer, we applied 15 algorithms to estimate the cancer incidence rates separately for men and women in 2012 and compared them to the national cancer incidence rates estimated from French registries by indirect age and sex standardization. The most accurate algorithm for men combined information from LTD status, outpatient anticancer drugs, radiotherapy sessions and primary or related discharge diagnosis of cancer, although it underestimated the cancer incidence (standardized incidence ratio (SIR) 0.85 [0.80-0.90]). For women, the best algorithm used the same definition of the algorithm for men but restricted hospital discharge to only primary or related diagnosis with an additional inpatient procedure or drug reimbursement related to cancer and gave comparable estimates to those from registries (SIR 1.00 [0.94-1.06]). The algorithms proposed could be used for cancer incidence monitoring and for future etiological cancer studies involving French healthcare databases. Copyright © 2017 John Wiley & Sons, Ltd.

    Breast cancer is the most common malignancy in women around the world. Information on the incidence and mortality of breast cancer is essential for planning health measures. This study aimed to investigate the incidence and mortality of breast cancer in the world using age-specific incidence and mortality rates for the year 2012 acquired from the global cancer project (GLOBOCAN 2012) as well as data about incidence and mortality of the cancer based on national reports. It was estimated that 1,671,149 new cases of breast cancer were identified and 521,907 cases of deaths due to breast cancer occurred in the world in 2012. According to GLOBOCAN, it is the most common cancer in women, accounting for 25.1% of all cancers. Breast cancer incidence in developed countries is higher, while relative mortality is greatest in less developed countries. Education of women is suggested in all countries for early detection and treatment. Plans for the control and prevention of this cancer must be a high priority for health policy makers; also, it is necessary to increase awareness of risk factors and early detection in less developed countries.

    2016-08-01

    Full Text Available Uterine sarcomas account for 3–7% of all uterine cancers. Because of their rarity, unknown etiology, and highly divergent genetic aberration, there is a lack of consensus on risk factors for occurrence and predictive poor outcomes as well as optimal therapeutic choices. Tumor types according to the World Health Organization classification include leiomyosarcoma, endometrial stroma sarcoma, and undifferentiated sarcoma. Staging is done using the 2014 Federation International Gynecology and Obstetrics and 2010 American Joint Committee on Cancer tumor, lymph node, and metastases systems. Tumor grade can be classified based on the French Federation of Cancer Centers Sarcoma Group system or the Broder’s system that incorporates tumor differentiation, mitotic count, and tumor necrosis. This review is a series of articles discussing uterine sarcoma, and this is Part I, which focuses on one of the subtypes of uterine sarcomas—uterine leiomyosarcoma. The clinical characteristics, diagnosis, outcome, and recent advances are summarized in this article.

  8. The Increasing Incidence of Thyroid Cancer: The Influence of Access to Care

    Sikora, Andrew G.; Tosteson, Tor D.

    2013-01-01

    Background The rapidly rising incidence of papillary thyroid cancer may be due to overdiagnosis of a reservoir of subclinical disease. To conclude that overdiagnosis is occurring, evidence for an association between access to health care and the incidence of cancer is necessary. Methods We used Surveillance, Epidemiology, and End Results (SEER) data to examine U.S. papillary thyroid cancer incidence trends in Medicare-age and non–Medicare-age cohorts over three decades. We performed an ecologic analysis across 497 U.S. counties, examining the association of nine county-level socioeconomic markers of health care access and the incidence of papillary thyroid cancer. Results Papillary thyroid cancer incidence is rising most rapidly in Americans over age 65 years (annual percentage change, 8.8%), who have broad health insurance coverage through Medicare. Among those under 65, in whom health insurance coverage is not universal, the rate of increase has been slower (annual percentage change, 6.4%). Over three decades, the mortality rate from thyroid cancer has not changed. Across U.S. counties, incidence ranged widely, from 0 to 29.7 per 100,000. County papillary thyroid cancer incidence was significantly correlated with all nine sociodemographic markers of health care access: it was positively correlated with rates of college education, white-collar employment, and family income; and negatively correlated with the percentage of residents who were uninsured, in poverty, unemployed, of nonwhite ethnicity, non-English speaking, and lacking high school education. Conclusion Markers for higher levels of health care access, both sociodemographic and age-based, are associated with higher papillary thyroid cancer incidence rates. More papillary thyroid cancers are diagnosed among populations with wider access to healthcare. Despite the threefold increase in incidence over three decades, the mortality rate remains unchanged. Together with the large subclinical reservoir of

    This prospective study was performed to define the efficiency of FDG-PET in detecting primaries and in preoperatively assessing lymph node metastases of cervical cancer. Forty one patients with cervical cancer were investigated with PET (370 MBq F-18-FDG, Siemens ECAT EXACT HR+, visual evaluation) and MRI prior radical hysterectomy with pelvic, and additionally 12 cases paraortal, lymphadenectomies. Histopathological evaluation verified in all cases the evidence of cervical cancer except in one case, where the tumor was completely removed by conisation procedure. Sensitivity of PET and MRI were 95% and 85%, respectively. In 16/82 pelvic lymph node sites metastases were histologically detected (7 x micrometastases). Sensitivity, specificity, positive positive and negative predictive value were 50%, 85%, 44% and 88% for PET and 31%, 90%, 40% and 86% for MRI. Out of the 12 cases with dissection of paraortal lymph nodes, metastases were found histologically in 3 cases. PET detected 2/3 truly with no false positive result while CT detected 0/3 cases with no false positive findings. It is concluded that PET can detect cervical cancer with high accuracy. The accuracy of PET and MRI was similar for detection of pelvic metastases. Both methods have limited sensitivity due to the high incidence of micrometastases. PET was more accurate than CT in detection of paraortal metastases

    Analysis was performed on the relationships between the organ dose-equivalent rate due to natural background radiation (mSv/a) and three parameters of cancer risk: the age-adjusted cancer incidence (patients x 10 5 persons x a -1 ) in 13 large areas, the standardized mortality ratio of cancers in 46 large areas, and the cancer mortality in the population aged more than 40 years old (cancer deaths x 10 5 persons x a -1 ) in 649 small areas. The age-adjusted liver cancer incidence in males fitted the exponential model significantly (p<0.01) and the relationship of stomach cancer mortality of aged males in small areas fitted the linear model significantly (p<0.05). No relationship was observed with regard to female cancer in either case. The relationships between the three parameters and various other cancers of both sexes were not statistically significant.

    This work aims to quantitatively assess RAPIDARC (RA) treatments versus three dimensional-Conformal Radiation Therapy with field to field technique (3D-Crt-Fin F). 11 patients with cervical cancer treated at our institution radically or adjuvant clinical stages I-III B were evaluated. The prescribed dose was 50 Gy (2 Gy / Fr). The RA plans consisted of two isocentric complete arcs and conformational plans of 4 isocentric fields (previous, subsequent, right side and left side) with 3D-Crt-Fin F technique; both cases carried out ??in the Eclipse version 10 planner with calculation algorithm analytical anisotropic algorithm (AAA) and volumetric optimization software (for VMAT plans). Homogeneity indices (Hi), conformity indices (CI) Sigma indices (S-Index), monitor units (MU) and the time required for each treatment were compared. The mean age was 52 years (32-65) of the 11 patients 9 were clinical stages I-II B. The Hi varied from 0.052 for RA to 0.163 for 3D-Crt-Fin F (p = 0.009), and the CI between 1.005 and 1.35 (p = 0.26), the S-index from 1.2 to 3.7 (p = 0.001) and the H-index of 1.08 to 1.15 (p = 0.24). All dose limits in risk organs were met with a significant difference in the RA plans versus 3D-Crt-Fin F. In patients with cervical cancer the treatment plans quality with the indices aforementioned seems to be better with the RA technique, being observed a significant reduction of radiation to surrounding organs.

    To describe the trends and occupational variation in the incidence of testicular cancer in the Nordic countries utilising national cancer registries, NORDCAN (NORDCAN project/database presents the incidence, mortality, prevalence and survival from >50 cancers in the Nordic countries) and NOCCA (Nordic Occupational Cancer) databases. We obtained the incidence data of testicular cancer for 5-year periods from 1960-1964 to 2000-2014 and for 5-year age-groups from the NORDCAN database. Morphological data on incident cases of seminoma and non-seminoma were obtained from national cancer registries. Age-standardised incidence rates (ASR) were calculated per 100 000 person-years (World Standard). Regression analysis was used to evaluate the annual change in the incidence of testicular cancer in each of the Nordic countries. The risk of testicular cancer in different professions was described based on NOCCA information and expressed as standardised incidence ratios (SIRs). During 2010-2014 the ASR for testicular cancer varied from 11.3 in Norway to 5.8 in Finland. Until 1998, the incidence was highest in Denmark. There has not been an increase in Denmark and Iceland since the 1990s, whilst the incidence is still strongly increasing in Norway, Sweden, and Finland. There were no remarkable changes in the ratio of seminoma and non-seminoma incidences during the past 50 years. There was no increase in the incidences in children and those of pension age. The highest significant excess risks of testicular seminoma were found in physicians (SIR 1.48, 95% confidence interval [CI] 1.07-1.99), artistic workers (SIR 1.47, 95% CI 1.06-1.99) and religious workers etc. (SIR 1.33, 95% CI 1.14-1.56). The lowest SIRs of testicular seminoma were seen amongst cooks and stewards (SIR 0.56, 95% CI 0.29-0.98), and forestry workers (SIR 0.64, 95% CI 0.47-0.86). The occupational category of administrators was the only one with a significantly elevated SIR for testicular non-seminoma (SIR 1.21, 95

    Incidence rates of different cancers have been calculated for the black population of Harare, Zimbabwe for a 20-year period (1991-2010) coinciding with continuing social and lifestyle changes, and the peak, and subsequent wane, of the HIV-AIDS epidemic. The overall risk of cancer increased during the period in both sexes, with rates of cervix and prostate cancers showing particularly dramatic increases (3.3% and 6.4% annually, respectively). By 2004, prostate cancer had become the most common cancer of men. The incidence of cancer of the esophagus, formerly the most common cancer of men, has remained relatively constant, whereas rates of breast and cervix cancers, the most common malignancies of women, have shown significant increases (4.9% and 3.3% annually, respectively). The incidence of Kaposi sarcoma increased to a maximum around 1998-2000 and then declined in all age groups, and in both sexes The incidence of squamous cell cancers of the conjunctiva is relatively high, with temporal trends similar to those of Kaposi sarcoma. Non-Hodgkin lymphoma, the fifth most common cancer of men and fourth of women, showed a steady increase in incidence throughout the period (6.7-6.9% annually), although rates in young adults (15-39) have decreased since 2001. Cancer control in Zimbabwe, as elsewhere in sub-Saharan Africa, involves meeting the challenge of emerging cancers associated with westernization of lifestyles (large bowel, breast and prostate), while the incidence of cancers associated with poverty and infection (liver, cervix and esophagus) shows little decline, and the residual burden of the AIDS-associated cancers remains significant.

    Cancer is a major public health problem in Iran and many other parts of the world. The cancer incidence is different in various countries and in country provinces. Geographical differences in the cancer incidence lead to be important to conduct an epidemiological study of the disease. This study aimed to investigate cancer epidemiology and trend in the province of Qom, located in center of Iran. This is an analytical cross-sectional study carried out based on re-analysis cancer registry report and the disease management center of health ministry from 2004 to 2008 in the province of Qom. To describe incidence time trends, we carried out join point regression analysis using the software Join point Regression Program, Version 4.1.1.1. There were 3,029 registered cases of cancer during 5 years studied. Sex ratio was 1.32 (male to female). Considering the frequency and mean standardized incidence, the most common cancer in women were breast, skin, colorectal, stomach, and esophagus, respectively while in men the most common cancers included skin, stomach, colorectal, bladder, and prostate, respectively. There was an increasing and significant trend, according to the annual percentage change (APC) equal to 8.08% (CI: 5.1-11.1) for all site cancer in women. The incidence trend of all cancers was increasing in this area. Hence, planning for identifying risk factors and performing programs for dealing with the disease are essential.

    Over the past several decades, there has been a reported increase in the incidence of thyroid cancer in many countries. We previously reported an increase in thyroid cancer incidence across continents between 1973 and 2002. Here, we provide an update on the international trends in thyroid cancer between 2003 and 2007. We examined thyroid cancer incidence data from the Cancer Incidence in Five Continents (CI5) database for the period between 1973 and 2007 from 24 populations in the Americas, Asia, Europe, Africa and Oceania, and report on the time trends as well as the distribution by histologic type and gender worldwide. The incidence of thyroid cancer increased during the period from 1998-2002 to 2003-2007 in the majority of populations examined, with the highest rates observed among women, most notably in Israel and the United States SEER registry, at over 14 per 100,000 people. This update suggests that incidence is rising in a similar fashion across all regions of the world. The histologic and gender distributions in the updated CI5 are consistent with the previous report. Our analysis of the published CI5 data illustrates that the incidence of thyroid cancer increased between 1998-2002 and 2003-2007 in most populations worldwide, and rising rates continue in all regions of the world.

    Survival data, prognostic factors, and patterns of failure were retrospectively analyzed for a total of 76 patients with adenocarcinoma of the uterine cervix treated between January 1981 and December 1987, which represents 4.1% of all primary cervical carcinomas treated, at Department of Radiation Oncology, Yensei Cancer Center, Yonsei University College of Medicine. The mean age of the patients was 49years(range, 27-79years) and the peak incidence was in the group 50 to 59years of age. More half of the patients were postmenopausal (46/76=60.5%). Most patients(76%)had abnormal vaginal bleeding either alone or in combination with other symptoms. The proportion of stage Iib was 43.4%. There were 4 major histologic subtypes: pure adenocarcinoma(48/76=63.2%), adenosquamous carcinoma(20/76=26.3%), papillary (5/76=6.6%) and clear cell carcinoma(3/76=3.9%). Of the many clinicopathologic variables evaluated for prognosis, the most significant prognostic factors were stage of disease and the size of tumor. The overall 5-year survival rate was 68%, and the 5-year survival rates for stage Ib, II and III were 90%, 66% and 54%, respectively. Control of pelvic tumors was achieved in 938%, 90.2% and 50.0% of cases of stage Ib, II and III disease, respectively. In present study, treatment modalities (radiation therapy alone/combined operative and radiation therapy) did not affect the local control of tumor and the survival

    Objective: This study aimed to describe the sex disparities on cancer incidence and mortality in Jiashan population. Methods: All data concerning incident and death cases of cancers were gathered from the database of Cancer Registry in Jiashan county. Data from the 2010 China census was used as the standard population. Sex-specific age-standardized incidence rates (ASIRs), mortality rates (ASMRs) per 100 000 persons for all cancers and types of each cancer were calculated for the years of 1990 to 1999, 2000 to 2009, 2010 to 2014, and 1990 to 2014. In addition, the corresponding male-to-female incidence rate ratios ( IRRs ) and mortality rate ratios ( MRRs ) were also calculated. Results: The ASIR of all cancers was 226.13/10(5) for the whole period of 1990 to 2014, with 266.04/10(5) for males and 187.22/10(5) for females, respectively. The corresponding IRR was 1.42 (95 %CI : 1.39-1.46), with significant difference noticed in the incidence rates between males and females ( P ASMR of all cancers was 155.39/10(5), with 206.55/10(5) for males and 104.98/10(5) for females, respectively. The corresponding MRR was 1.97 (95 % CI : 1.91-2.03), with significant difference between males and females ( P <0.05). Among all the cancer types, only gallbladder cancer and thyroid cancer showed female predominance in both incidence and mortality, with male predominance in all the remaining cancers. Conclusion: Finding from our study suggested that a male predominance in both incidence and mortality for a majority of cancers in Jiashan population.

    In recent decades, several Western countries have reported an increase in oropharyngeal and anal cancers caused by human papillomavirus (HPV). Trends in HPV-associated cancers in Asia have not been as well described. We describe the epidemiology of potentially HPV-related cancers reported to the Singapore Cancer Registry from 1968–2012. Analysis included 998 oropharyngeal squamous cell carcinoma (OPSCC), 183 anal squamous cell carcinoma (ASCC) and 8,019 invasive cervical cancer (ICC) cases. Additionally, 368 anal non-squamous cell carcinoma (ANSCC) and 2,018 non-oropharyngeal head and neck carcinoma (non-OP HNC) cases were included as comparators. Age-standardized incidence rates (ASR) were determined by gender and ethnicity (Chinese, Malay and Indian). Joinpoint regression was used to evaluate annual percentage change (APC) in incidence. OPSCC incidence increased in both genders (men 1993–2012, APC = 1.9%, pSingapore, but Pap screening programs have led to consistently decreasing incidence. PMID:26720001

    A plant processing radium and uranium ores has been operating in the town of Port Hope since 1932. Given the nuclear industry located in the community and ongoing public health concerns, cancer incidence rates in Port Hope were studied for a recent 16 year period (1992–2007) for continued periodic cancer incidence surveillance of the community. The cancer incidence in the local community for all cancers combined was similar to the Ontario population, health regions with similar socio-economic characteristics in Ontario and in Canada, and the Canadian population. No statistically significant differences in childhood cancer, leukaemia or other radiosensitive cancer incidence were observed, with the exception of statistically significant elevated lung cancer incidence among women. However, the statistical significance was reduced or disappeared when the comparison was made to populations with similar socio-economic characteristics. These findings are consistent with previous ecological, case-control and cohort studies conducted in Port Hope, environmental assessments, and epidemiological studies conducted elsewhere on populations living around similar facilities or exposed to similar environmental contaminants. Although the current study covered an extended period of time, the power to detect risk at the sub-regional level of analysis was limited since the Port Hope population is small (16 500). The study nevertheless indicated that large differences in cancer incidence are not occurring in Port Hope compared to other similar communities and the general population. (paper)

    Objective: The present study was aimed at developing a thermoluminescent dosimetric system capable of assessing the doses delivered to the rectum of patients submitted to high-dose-rate brachytherapy for uterine cervix cancer. Materials and methods: LiF:Mg,Ti,Na powder was the thermoluminescent material utilized for evaluating the rectal dose. The powder was divided into small portions (34 mg) which were accommodated in a capillary tube. This tube was placed into a rectal probe that was introduced into the patient's rectum. Results: The doses delivered to the rectum of six patients submitted to high-dose-rate brachytherapy for uterine cervix cancer evaluated by means of thermoluminescent dosimeters presented a good agreement with the planned values based on two orthogonal (anteroposterior and lateral) radiographic images of the patients. Conclusion: The thermoluminescent dosimetric system developed in the present study is simple and easy to be utilized as compared to other rectal dosimetry methods. The system has shown to be effective in the evaluation of rectal doses in patients submitted to high-dose-rate brachytherapy for uterine cervix cancer. (author)

    García-Carrancá, A; Gariglio, P V

    1993-01-01

    Papillomaviruses (wart viruses) are responsible for the development of benign and malignant epithelial lesions in mammals. More than 60 different types of human papillomaviruses (HPVs) have been isolated to date. Some of them are major candidates as etiologic agents in cervical cancer. DNA from HPV types 16, 18 and 33 is usually found integrated in about 90 percent of genital carcinomas. Integration of the viral DNA into the cellular genome may be an important step towards the development of malignancy. Two early genes of HPVs (E6 y E7) are involved in cellular transformation. Another early gene (E2) participates in gene control by directly binding to conserved DNA motifs in the viral genome. Several protein factors of viral and cellular origin interact with the regulatory region of HPVs and participate in the regulation transcription of oncogenes E6 and E7. Cellular factors, such as immune system and oncogene and anti-oncogene alterations, seem to play an important role in papillomavirus-associated cervical carcinogenesis.

    Purpose. -Evaluate the results of the treatment of small uterine cervix cancer with the association of surgery and postoperative vaginal brachytherapy, without unfavourable prognostic factors. Patients and methods. -After radical hysterectomy with lymphadenectomy, 29 women (mean age: 44 years) with carcinoma < 25 mm (26 stage IB1, 3 IIA, mean size: 15 mm) were treated by post-operative prophylactic vaginal brachytherapy using low dose rate. Ovarian transposition was performed at the surgical time in 14 young women (mean age 35 years). Results. - The actuarial specific survival rates at 5 and 10 years were 100% and 90% respectively, with a mean follow-up 75 months. Only one local recurrence was observed. The rate of grade 1 post-operative complication was 7%. The conservation rate of the ovarian function was 85% for young women. Conclusion. -Treatment of small volume
