To prevent cancer cells replacing and outnumbering their functional somatic counterparts, the most effective solution is their removal. Classical treatments rely on surgical excision, chemical or physical damage to the cancer cells by conventional interventions such as chemo- and radiotherapy, to eliminate or reduce tumour burden. Cancer treatment has in the last two decades seen the advent of increasingly sophisticated therapeutic regimens aimed at selectively targeting cancer cells whilst sparing the remaining cells from severe loss of viability or function. These include small molecule inhibitors, monoclonal antibodies and a myriad of compounds that affect metabolism, angiogenesis or immunotherapy. Our increased knowledge of specific cancer types, stratified diagnoses, genetic and molecular profiling, and more refined treatment practices have improved overall survival in a significant number of patients. Increased survival, however, has also increased the incidence of associated challenges of chemotherapy-induced morbidity, with some pathologies developing several years after termination of treatment. Long-term care of cancer survivors must therefore become a focus in itself, such that along with prolonging life expectancy, treatments allow for improved quality of life.
为防止癌细胞取代并超过其功能性体细胞对应物,最有效的解决办法是将它们清除。传统治疗方法依靠手术切除,以及通过化疗和放疗等常规干预对癌细胞进行化学或物理损伤,以消除或减轻肿瘤负担。在过去二十年中,癌症治疗出现了越来越复杂的治疗方案,旨在选择性地靶向癌细胞,同时避免其余细胞严重丧失活力或功能。这些治疗方法包括小分子抑制剂、单克隆抗体以及大量影响代谢、血管生成或免疫治疗的化合物。我们对特定癌症类型、分层诊断、基因和分子谱分析的了解不断增加,以及更精细的治疗方法,显著提高了大量患者的总体生存率。然而,生存率的提高也增加了化疗诱导的发病率相关挑战的发生率,一些病理状况在治疗结束数年后才出现。因此,癌症幸存者的长期护理本身必须成为一个重点,以便在延长预期寿命的同时,治疗能够提高生活质量。
