Human immunodeficiency virus (HIV)-infected individuals have a higher risk of some types of cancer. A chronic immunodeficiency state, increased survival in the highly active antiretroviral therapy (HAART) era and predisposition to certain oncogenic viral infections have been postulated as the main reasons. While, the incidence of acquired immunodeficiency syndrome (AIDS) defining cancers (ADCs) is declining in the post-HAART era, non-AIDS-defining cancers (NADCs) are becoming an important cause of mortality in these patients.
Analysis of the data of HIV-infected patients registered at an apex centre was done for 7 years. All patients were subjected to routine investigations on presentation (baseline) and during follow-up for the occurrence of any malignant disease. CD4 cell counts before starting anti-retroviral therapy and before the diagnosis of malignancy were noted. The date of the last review and the current status/outcome were recorded.
Out of 1258, 17 patients were diagnosed with various malignancies. Seven patients (41.2%) had ADCs and the remaining 10 (58.8%) had NADCs. The mean duration between diagnosis of HIV infection and diagnosis of malignancy was 59.53 months. The mean survival duration from the diagnosis of malignancy for all cases was 21 months. The mean survival duration was 29 months and 15 months for ADC and NADC group respectively.
NADCs are on the rise in the era of effective use of HAART and increasing life span of HIV patients. The index of suspicion for cancer should be higher in such patients, especially compared to opportunistic infections in view of good immunovirologic status.
感染人类免疫缺陷病毒(HIV)的个体患某些类型癌症的风险更高。慢性免疫缺陷状态、高效抗逆转录病毒疗法(HAART)时代生存率的提高以及对某些致癌病毒感染的易感性被认为是主要原因。虽然在HAART时代之后,获得性免疫缺陷综合征(AIDS)定义的癌症(ADC)的发病率正在下降,但非AIDS定义的癌症(NADC)正成为这些患者死亡的重要原因。
对一家顶级中心登记的HIV感染患者的数据进行了7年的分析。所有患者在就诊时(基线)和随访期间均接受常规检查,以检查是否发生任何恶性疾病。记录开始抗逆转录病毒治疗前和诊断恶性肿瘤前的CD4细胞计数。记录最后一次复查的日期和当前状态/结果。
在1258名患者中,17名被诊断患有各种恶性肿瘤。7名患者(41.2%)患有ADC,其余10名(58.8%)患有NADC。HIV感染诊断与恶性肿瘤诊断之间的平均持续时间为59.53个月。所有病例从诊断恶性肿瘤起的平均生存时间为个月。ADC组和NADC组的平均生存时间分别为29个月和15个月。
在有效使用HAART且HIV患者寿命延长的时代,NADC的发病率正在上升。对于此类患者,尤其是鉴于良好的免疫病毒学状态,与机会性感染相比,对癌症的怀疑指数应更高。
