人乳头状瘤病毒感染与头颈部恶性肿瘤的关系 总被引:3,自引:0,他引:3
人乳头状瘤病毒是一种致瘤性DNA病毒,在其90个亚型中以高危型HPV-16,HPV-18,HPV-33等与人类头颈部恶性肿瘤关系密切。其致部机理是通过引起P53,pRB基因的突变,从而导致细胞转化及过度增殖,在不同部位的头颈部恶性肿瘤中HPV的检出率存在差异,口腔、吕咽及喉部鳞状细胞癌中HPV检出率高而鼻咽癌中检出率低,在头颈部腺癌和淋巴瘤中HP的感染鲜见报道,颈总转移淋巴结中HPV的检测可以帮助临床提高原发病灶的检出率。 相似文献

临床上,合并病毒感染的恶性肿瘤患者越来越多,在给予抗肿瘤治疗时也会导致患者机体免疫功能下降而引起病毒再激活。病毒再作用于机体,可表现出不同的临床表现,常常需要抗病毒治疗的介入,这可能会导致抗肿瘤治疗中断或停止,进而影响患者预后。近年来,国内外学者针对在抗肿瘤内科治疗过程中预防病毒再激活开展了众多临床试验,为恶性肿瘤患者预防病毒再激活提供了新的理论依据。本文就恶性肿瘤合并乙型肝炎病毒、丙型肝炎病毒和人类免疫缺陷病毒对患者抗肿瘤内科治疗的影响及抗肿瘤治疗期间的抗病毒治疗策略进行综述。 相似文献

鼻咽癌组织学类型与EB病毒感染的关系 总被引:3,自引:0,他引:3
[目的]研究不同组织学类型鼻咽癌与EB病毒感染的关系.[方法]收集4种主要组织学类型的鼻咽癌288例,用原位杂交方法检测癌巢及肿瘤浸润淋巴细胞的EB病毒编码小RNAs(EBERs)的表达,其中EBERs阳性的31例非角化性癌和19例角化性鳞状细胞癌,进一步用原位杂交法检测EB病毒溶解期产物EA-D(early antigen-diffuse,EA-D)mRNA的表达.[结果]接近100%的鼻咽非角化性癌(99.32%,145/146)显示出EBERs阳性信号,鼻咽腺癌EBERs阳性率明显小于角化性鳞状细胞癌,分别是35.90%(14/39)、84.38%(81/96).双向分化的腺鳞癌的EBERs阳性率(71.43%,5/7)处于非角化性癌/角化性鳞状细胞癌(93.39%,226/242)与腺癌(35.90%,14/39)之间.非角化性鳞状细胞癌、腺癌、角化性鳞状细胞癌分别有23例(23/146,15.75%)、16例(41.03%,16/39)、31例(31/96,32.29%)可见表达EBERs的肿瘤浸润淋巴细胞.角化性鳞状细胞癌的EA-D mRNA表达率高于非角化性癌,分别是78.95%(15/19)、16.13%(5/31).[结论]4种不同组织学类型鼻咽癌的EB病毒感染率与感染状态不完全一致.鼻咽非角化性癌总是与EB病毒的潜伏感染密切相关,角化性鳞状细胞癌组织中的分化不良成分也与EB病毒潜伏感染关系密切,其中分化良好的癌细胞经常可以检测到EB病毒的溶解性感染产物表达.鼻咽腺癌与EB病毒感染的关系并不密切. 相似文献

早期研究一致认为细胞间隙连接蛋白(connexin)基因是抑癌基因,在乳腺癌中起抑制肿瘤发生发展的作用,但近年研究发现在很多转移性乳腺癌中connexin表达反而升高,connexin基因可能促进乳腺癌的远处转移.故推测在乳腺癌发生发展、侵袭转移中,connexin通过多种作用机制扮演了不同的角色.在乳腺癌治疗中合理应用connexin将改善患者的疗效. 相似文献

We report a case of small cell lung cancer in a patient with human immunodeficiency virus (HIV) infection. The patient was a 51-year-old man diagnosed 8 years previously as seropositive for HIV, who was admitted to our hospital for re-evaluation of antiretroviral medications due to multidrug resistance. Chest radiograph revealed an abnormal hilar shadow subsequently confirmed to be small cell lung cancer. He received chemotherapy concurrently with highly active antiretroviral therapy (HAART), and lived for 14 months after the diagnosis. The prognosis of lung cancer in HIV-seropositive patients is very poor, and adverse effects of chemotherapy occur more frequently than in other patients. However, the simultaneous antiretroviral agents and combination chemotherapy was successful. Such treatment may be effective despite an otherwise poor prognosis, including HIV infection. 相似文献

PurposeTo examine the annual hospital volume of surgery in relation to survival in colorectal cancer. Previous studies on hospital volume and survival following colorectal cancer surgery are conflicting.MethodsAll 49 032 patients who underwent resection for colorectal cancer in 1987–2016 in Finland were included, with complete follow-up until December 31, 2019. Primary outcome was 5-year mortality. Cox regression provided hazard ratios (HR) with 95% confidence intervals (CI) for quartiles of annual hospital volume for colorectal surgery, adjusted for calendar period, age, sex, comorbidity, stage, tumor location and oncological therapy. Additionally, colon and rectal cancer surgery were assessed separately. Sensitivity analysis of patients with confirmed curative intent was conducted.ResultsCompared to highest quartile (≥108 resections annually), lowest hospital volume (≤37 resections annually) was associated with slightly increased 5-year all-cause mortality (adjusted HR 1.07, 95% CI 1.02–1.12). A pre-planned subgroup-analysis suggested a slightly improved 5-year survival in high-volume institutions for rectal cancer, but not colon cancer surgery. Sensitivity analysis including only those operated with confirmed curative intent suggested no differences between hospital volume groups in colorectal, colon or rectal cancer for 5-year all-cause mortality.ConclusionHigher hospital volume is associated with slightly improved all-cause 5-year mortality in colorectal cancer surgery, but this effect may be limited to rectal cancer surgery only. Volume-outcome relationship in rectal cancer surgery should be investigated further using large datasets. These results do not support centralization of colon cancer surgery based on hospital volume only. 相似文献

目的 分析比较人类免疫缺陷病毒(HIV)阳性与阴性弥漫大B细胞淋巴瘤患者的临床特点及疗效。方法 收集博茨瓦纳弗朗西斯敦市仰加奎医院肿瘤内科2012年3月至2015年3月诊治的弥漫大B细胞淋巴瘤患者共71例,其中HIV阳性37例,HIV阴性34例,给予CHOP方案一线化疗,对两组的临床特点及疗效进行分析。结果 与HIV阴性组相比,HIV阳性组B症状发生率高(56.8% vs. 29.4%; P=0.020),更容易出现胃肠道(37.8% vs. 14.7%; P=0.028)、肝(29.7% vs. 9.7%; P=0.027)、肺(27.0% vs. 9.7%; P=0.048)浸润。HIV阳性组与HIV阴性组治疗完全缓解率分别为18.9%(7/37)与41.2%(14/34)(P=0.040);客观有效率分别为48.6%(18/37)与70.6%(24/34)(P=0.060)。HIV阳性组化疗后出现贫血、白细胞下降及继发感染比例高于HIV阴性组(均P<0.05)。HIV阳性组中有24例在确诊淋巴瘤前已给予高效价抗逆转录病毒治疗(highly active antiretroviral therapy,HAART)治疗,13例确诊后给予HARRT治疗,其客观有效率分别为41.7%和61.5%(P=0.248)。CD4+细胞数>200/mm3和≤200/mm3患者,其客观有效率分别为71.4%和34.8%(P=0.031)。结论 HIV阳性患者就诊时表现出更强的侵袭性。结合HARRT治疗,CHOP方案可使HIV阳性患者达到类似于HIV阴性患者的客观有效率,但完全缓解率低。HIV阳性组患者HARRT起始治疗时间不影响近期疗效。CD4+细胞数低是近期疗效不良的预测因素。 相似文献

IntroductionOptimized treatment of primary rectal cancer might have influenced treatment characteristics and outcome of locally recurrent rectal cancer (LRRC). Subgroup analysis of the Dutch TME trial showed that preoperative radiotherapy (PRT) for the primary tumour was an independent poor prognostic factor after diagnosis of LRRC. This cross-sectional population study aimed to evaluate treatment and overall survival (OS) of LRRC patients, stratified for prior preoperative radiotherapy (PRT) and intention of treatment of LRRC.MethodsAll patients developing LRRC were selected from a collaborative Snapshot study on 2095 surgically treated rectal cancer patients from 71 Dutch hospitals in the year 2011. Cox proportional hazard analysis was performed to determine predictors for OS.ResultsA total of 107 LRRC patients (5.1%) were included, of whom 88 (82%) underwent PRT for their primary tumour. LRRC was treated with initial curative intent in 31 patients (29%), with eventual resection in 20 patients (19%). Median OS was 22 and 8 months after curative and palliative intent treatment, respectively (p < 0.001). Initial CRM positivity and palliative intent treatment were associated with worse OS after LRRC, while prior PRT was not.ConclusionsThis cross-sectional study revealed that rectal cancer patients, who underwent curative resection in the Netherlands in 2011 and subsequently developed local recurrence, were amenable for again curative intent treatment in 29%, with a corresponding median survival of 22 months. Prior PRT was not significantly associated with survival after diagnosis of LRRC. 相似文献

Background: There are only three published studies that have examined unstaged cancers, including breast, prostate and colorectal cancer, but none have specifically examined which aspects of tumor staging were missing. The objective of the study was to identify which stage components were missing, to characterize and to identify predictors of unstaged cancer, and to evaluate prognosis of unstaged in colon and rectal cancer patients. Methods: Data on all colon and rectal cancer cases diagnosed during 1991 to 2002 were identified from the Surveillance, Epidemiology and End Results (SEER) database. Information included in the analysis encompassed socio-demographics; tumor size (T); number of lymph nodes (N); metastases (M); SEER summary stage; SEER sites; cancer treatment; month and year of diagnosis; and last date known alive. Results: The study included 128,418 colon and 44,616 rectal cancer patients. Overall, 5.1% of colon and 7.8% of rectal cancer patients were unstaged. Compared to staged cases, both unstaged colon and rectal cancer cases were more likely to be older, African American, female, diagnosed in the Northeast and South, and have unknown treatment (all p < 0.001). The stage component of M was found to be the factor missing most frequently which attributed most to being unstaged. Survival was significantly higher in unstaged and the overall cohort compared to distant staged colon and rectal cancer patients (both p < 0.001) except for patients ≥ 65 years old (p > 0.99). Conclusions: Given that unstaged cases differ from staged, the findings have methodological implications in accounting for unstaged cases in epidemiological and health services research. 相似文献

早期诊断、早期治疗以及选择正确的治疗模式是转移性鼻咽癌治疗的关键.目前,在鼻咽癌远处转移的诊断中,正电子发射计算机断层显像(PET)-CT是最优的检查方法.在治疗方面,以铂类为基础的化疗是首选的标准治疗方式,分子靶向治疗则有可能进一步提高疗效.如果患者转移灶局限,在使用化疗使病情得到控制后,针对转移灶进行局部姑息性治疗,有可能改善预后. 相似文献
