Background:

In addition to lung cancers, tuberculosis infections have been associated with increased risk of non-pulmonary malignancies in case reports. Our population-based study employed standardized incidence ratios (SIRs) to systemically survey non-pulmonary cancer risks after tuberculosis infections.

Methods:

Data of patients who had newly diagnosed tuberculosis, were aged 20 years or older, and had no prior cancer or tuberculosis were sampled from the Taiwan National Health Insurance database between 2000 and 2010. SIRs compared cancer incidence in patients with tuberculosis infections to the general population. SIRs of specific cancers were further analyzed with respect to gender and time after tuberculosis infections.

Results:

After a follow-up period of 28 866 person–years, 530 tuberculosis cases developed cancers compared with 256 cases in the general populations (2.07, 95% confidence interval (CI), 1.90–2.26). The SIR of non-pulmonary malignancies was also increased (1.71, 95% CI, 1.54–1.90). For males, SIRs were increased within 1 year after tuberculosis diagnosis for the following cancers: head and neck, esophageal, colorectal, liver, lung, melanomas, and Hodgkin''s disease. SIRs were increased for liver, biliary, lung, and bladder cancers beyond the first year after tuberculosis diagnosis. For females, SIRs were increased for leukemia, esophageal, and lung cancers within the first year, and only for leukemia beyond 1 year post diagnosis.

Conclusion:

Having found increased risks of several cancers that differ with gender and time after tuberculosis diagnosis, physicians may consider these factors in patients following tuberculosis diagnosis.  相似文献

A retrospective comparison of cancer incidence data and, where relevant, population data with 16,955 first-time users (patients, relatives and friends) of a national cancer information service (CancerBACUP) during the period April 1995 to March 1996 is presented. The number of events observed was compared with the number of events expected, were the national rates of cancer incidence and population demographics apply. Standardized incidence ratios (SIRs) (observed - expected ratios) were used to indicate any differences. Statistically significant differences (P < 0.001) in the observed and expected sex, age and primary site distribution of patients enquired about were found. Statistically significant differences (P < 0.001) were also identified for the age, employment status, socioeconomic class and geographical location of first-time enquirers (patients, relatives and friends). Enquiries about brain, testis and breast cancers and non-Hodgkin's lymphoma (NHL) were substantially higher than expected; enquiries about bladder, lung, stomach and colorectal cancers were much lower than expected. As the service is provided via a freephone number, it is available to all, and users might be expected to be randomly distributed across the variables listed. The underlying reasons for the differences identified need to be investigated, and the role of information in the care of cancer patients should be formally evaluated.  相似文献

In Pakistan, malignant diseases are increasing day by day, but no epidemiological cancer study on large scale has been designed. The main objective of this study was to provide a baseline data on frequency, morphological types, gender and age distribution etc., of breast cancer in North-West Frontier Province and Federally Administered Tribal Areas of Pakistan, and to compare it with the published data. In this context, 2134 breast cancer patients (2059 female and 75 male) registered at Institute of Radiotherapy and Nuclear Medicine, Peshawar from 1995 to 2001, were studied. Crude incidence, standardized incidence ratios (SIR, world) and age-specific incidence rates (ASIR) were determined both for male and female patients. Same morphological distribution was found in both genders. Moreover, breast cancer was found to be the most common malignancy among the women (96.49%). Male to female breast cancer ratio was found to be 3.5 times higher than the reported data. The highest ASIR of ∼10.6/100 000 per year among women was observed in the age group of 55–59 years. In men, the highest ASIR of 0.84/100 000 per year was observed in the age group of 65–69 years. The SIR (world) for women was 3.15/100 000 per year, while for male this was 0.13/100 000 per year.  相似文献

Evidence regarding cancer risk after borderline ovarian tumors (BOTs) is limited. We conducted a nationwide cohort study examining the incidence of nonovarian cancers in women with serous or mucinous BOTs compared with the general female population with up to 41 years of follow-up. Through the nationwide Pathology Registry, we identified nearly 5000 women with BOTs (2506 serous and 2493 mucinous) in Denmark, 1978 to 2018. We computed standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) as relative risk estimates of specific nonovarian cancers. Compared with general female population rates, women with serous BOTs had increased rates of particularly malignant melanoma (SIR = 1.9; 95% CI: 1.3-2.6), thyroid cancer (SIR = 3.0; 95% CI: 1.4-5.4) and myeloid leukemia (SIR = 3.2; 95% CI: 1.5-5.8), and women with mucinous BOTs had elevated rates of lung cancer (SIR = 1.7; 95% CI: 1.3-2.1), pancreatic cancer (SIR = 1.9; 95% CI: 1.2-2.9) and myeloid leukemia (SIR = 2.3; 95% CI: 0.9-4.7). We found no convincing association with neither breast nor colorectal cancer in women with BOTs. This is the first large nationwide study showing that women with specific types of BOTs have increased risks of several nonovarian cancers, likely due to some shared risk factors or genetic characteristics.  相似文献

Esophageal carcinoma is one of the most common malignant tumors, especially in China which is the high incidence area. As a result of mild symptoms of early-stage esophageal cancer, the majority of patients cannot be diagnosed until they develop to advanced cancer, and the treatment outcome of surgery or chemoradiotherapy is still unsatisfactory at present. The guidelines of esophageal cancer issued by National Comprehensive Cancer Network (NCCN) are regarded as important reference tools by clinical oncolog...  相似文献

BACKGROUND: The aim of this prospective study was to evaluate the value of F-18-fluorodeoxyglucose-positron emission tomography (FDG-PET) for early assessment of chemotherapy response in patients with advanced colorectal cancer. METHODS: Dynamic FDG-PET was carried out before and at 2 (n = 50) and 6 months (n = 19) after the start of treatment. Quantitative Patlak analysis [metabolic rate of glucose (MRGlu)] and a simplified method to measure glucose metabolism [standardized uptake value (SUV)] were evaluated. The predictive value of changes in glucose metabolism was assessed with Cox proportional regression analysis. Overall survival (OS) and progression-free survival (PFS) were calculated using Kaplan-Meier estimates. RESULTS: There was an increase in the rates of death (P = 0.049 for DeltaMRGlu PET1-2; P = 0.017 for DeltaSUV PET1-2; P = 0.032 for DeltaMRGlu PET1-3; P = 0.048 for DeltaSUV PET1-3) and progression (P = 0.026 for DeltaMRGlu PET1-2; P = 0.035 for DeltaSUV PET1-2; P = 0.041 for DeltaMRGlu PET1-3; P = 0.081 for DeltaSUV PET1-3) associated with worse response as assessed by PET on Cox proportional regression analysis. The OS and PFS analysis showed a significant predictive value at broad ranges of DeltaMRGlu and DeltaSUV cut-off levels. CONCLUSION: The degree of chemotherapy-induced changes in tumor glucose metabolism is highly predictive for patient outcome. The use of FDG-PET for therapy monitoring seems clinically feasible since simplified methods (SUV) are sufficiently reliable.  相似文献

Population-based evidence regarding risk of ovarian cancer after a borderline ovarian tumor (BOT) is sparse. We aimed to examine the incidence of specific types of ovarian cancer in women with serous or mucinous BOTs in a nationwide cohort study with up to 36 years of follow-up. Using the nationwide Danish Pathology Data Bank, we identified 4,281 women with a BOT (2,058 serous BOTs and 2,223 mucinous BOTs) in Denmark during 1978–2012. We computed standardized incidence ratios (SIRs) to compare the incidence of ovarian cancer among women with BOTs compared to general population rates. We found that a serous BOT was especially and strongly associated with subsequent serous ovarian cancer (SIR = 9.2; 95% CI: 6.8–12.2), and that a mucinous BOT was strongly related to mucinous ovarian cancer (SIR = 18.6; 95% CI: 10.8–29.8). The SIRs remained elevated ≥10 years after a serous BOT and up to 5–9 years after a mucinous BOT. The increased incidence of serous ovarian cancer in women with a serous BOT was mostly pronounced in women <50 years at the serous BOT diagnosis. In conclusion, women with a serous BOT experience long-term increased incidence of serous ovarian cancer, and women with a mucinous BOT have long-term elevated incidence of mucinous ovarian cancer compared to the general population. This is the first population-based study to show compelling evidence of the histo-specific increased risk of ovarian cancer following specific types of BOTs. Thus, these results are supportive of the hypothesis that BOTs may be precursor lesions to carcinomas of the corresponding histologic type.  相似文献

目的 探讨18F-FDG PET/CT化疗前SUVmax、Ki-67、p53、EGFR对三阴性乳腺癌(TNBC)及非三阴性乳腺癌(非TNBC)对新辅助化疗完全病理缓解(pathologic complete response, pCR)率的预测价值。方法 初治TNBC患者27例,非TNBC患者184例,在新辅助化疗前行18F-FDG PET/CT显像并测量其SUVmax,取化疗前乳腺肿瘤组织进行Ki-67、p53、EGFR免疫组织化学分析并计算化疗后完全pCR率。结果 TNBC新辅助化疗前的SUVmax明显高于非TNBC的SUVmax(P=0.045),TNBC新辅助化疗后pCR率明显高于非TNBC(P<0.001)。在TNBC以及非TNBC中,达到pCR组的化疗前SUVmax与未达到pCR组之间差异无统计学意义(P>0.05)。Ki-67、p53、EGFR阳性表达组的pCR率与阴性表达组之间差异无统计学意义(P>0.05)。结论 TNBC对新辅助化疗的敏感度高于非TNBC,且TNBC化疗前SUVmax高于非TNBC,提示TNBC具有较高的能量代谢。化疗前SUVmax以及Ki-67、p53、EGFR不能预测TNBC及非TNBC新辅助化疗的pCR。  相似文献

BACKGROUND:

The objective of the current study was to evaluate the prognostic significance of the maximum standardized uptake value (SUVmax) of F‐18 fluorodeoxyglucose (FDG) as measured by positron emission tomography (PET) in pelvic lymph nodes in patients with cervical cancer.

METHODS:

The authors studied cervical cancer patients with pelvic lymph node metastasis, as evidenced on FDG‐PET, who were treated between November 2003 and October 2008. The maximum dimension and SUVmax for the most FDG‐avid pelvic lymph node (SUVPLN) and the SUVmax of the primary cervical tumor (SUVcervix) were recorded from the FDG‐PET/computed tomography (CT) scan. The SUVPLN was analyzed for its association with treatment response, pelvic disease recurrence, disease‐specific survival, and overall survival.

RESULTS:

The population was comprised of 83 women with International Federation of Gynecology and Obstetrics (FIGO) stages IB1 to IIIB cervical cancer. The average SUVPLN was 6.9 (range, 2.1‐33.0), whereas the average SUVcervix was 14.0 (range, 3.2‐38.4). The SUVcervix and SUVPLN were found to be weakly correlated (correlation coefficient [R2] = 0.301). The average size of the pelvic lymph nodes was 2.1 cm (range, 0.6‐7.9 cm), and was also found to be only weakly associated with the SUVPLN (R2 = 0.225). The SUVPLN was found to be correlated with an increased risk of persistent disease after treatment (P = .0025), specifically within the pelvic lymph node region (P = .0003). The SUVPLN was found to be predictive of an increased risk of ever developing pelvic disease recurrence (P = .0035). Patients with a higher SUVPLN were found to have significantly worse disease‐specific (P = .0230) and overall survival (P = .0378) using Kaplan?Meier evaluation. A Cox proportional hazards model for the risk of pelvic disease recurrence was performed including SUVPLN, patient age, and tumor stage, and found only an increased SUVPLN to be an independent predictor.

CONCLUSIONS:

SUVPLN is a prognostic biomarker, predicting treatment response, pelvic recurrence risk, and disease‐specific survival in patients with cervical cancer. Cancer 2010. © 2010 American Cancer Society.  相似文献

BACKGROUND: We conducted a prospective two-group evaluation of pediatric cancer patients and their siblings regarding experiences and affective changes resulting from a 1-week summer camp experience. METHODS: The patients and siblings were assessed prior to camp (Baseline), at the end of camp (Follow-up 1), and again 4-6 months later (Follow-up 2). Assessments included standardized tests for depressive affects, social competency, and a measure of pleasure and participation in camp activities. RESULTS: Sixty-six children were assessed, including 31 (47%) patients and 35 (53%) siblings. Ages ranged from 7 to 17 years. Of the patient campers 19 (61%) had leukemia or lymphoma and 12 (39%) had solid tumors. Results showed marked changes in affective symptoms for patient campers over time (improvements), not shown by sibling campers. For patient campers these affective changes were not present immediately after camp, but were quite significant when measured 4-6 months later. Both patient and sibling campers reflected the same positive memories and pleasure in camp activities over time. For neither group did memories or pleasure fade over time. The camping experience did not have differential impacts on first time versus returning campers. Twelve campers (18% of sample) indicated suicidal ideation on the measure of depressive affects. They did well at camp and presented no special management issues. CONCLUSION: Expectations appear substantially different for patient versus sibling campers. The camping experience appeared to impact these groups differently, with patient campers impacted in ways not experienced by sibling campers.  相似文献
