Analysis and impact
根据 Ars Technica 的报道，这项研究指出，癌症手术等待时间的上升并非单一因素所致。原文提到，可能的影响因素包括医疗系统资源紧张、外科医生与手术室供给不足，以及新冠疫情后积压病例的持续消化。研究覆盖了多种癌症类型，但原文未提供具体癌种之间的差异数据。
从时间线来看，等待时间的恶化在疫情前已有迹象，疫情则进一步加剧了这一问题。报道称，许多医院在疫情期间暂停或推迟了择期手术，导致后续需求集中释放，而医疗系统的恢复速度未能跟上。与此同时，美国部分地区面临医护人员短缺和医院财务压力，这些结构性因素共同推高了患者从确诊到手术的等待周期。
原文未提供该研究的具体样本规模、数据来源机构名称或等待时间的绝对数值。对于患者而言，更长的等待时间可能意味着肿瘤在术前继续进展，增加治疗难度和不良预后的风险，但报道未就具体临床后果展开量化分析。

As cancer treatments have advanced and outcomes have improved, one aspect of cancer care in the US has consistently worsened over the last decade: the wait time for surgery.
According to a study in JAMA Surgery, patients with one of six types of cancer—breast, colon, lung, pancreatic, gastric, and esophageal—have faced longer wait times for surgery than in 2012. Timeliness is considered a core metric of healthcare quality, and delays in cancer surgery have been linked to poorer outcomes, including reduced survival rates and increased patient anxiety and distress.
The findings of the new study are based on data from over 2.7 million patients who had been diagnosed with non-metastatic stage I–III cancers requiring surgery between 2012 and 2023. Researchers led by cancer expert Timothy Donahue at the University of California, Los Angeles, broke that time frame up into four groups: 2012–2015, 2016–2019, 2020–2021, and 2022–2023 to see how wait times have changed over the period.
