摘要

背景肝脏和肺部是结直肠癌(CRC)最常见的转移部位。它们受累的临床表现有五种:仅肺部转移、仅肝脏转移、先肺部转移后肝脏转移、先肝脏转移后肺部转移以及肺部和肝脏同时转移。我们利用临床和形态学数据研究了这些情况下的克隆轨迹。材料和方法共评估了 465 例(CRC)患者,其中肝转移 7952 例,肺转移 6406 例。根据转移灶的数量、时间和线性/平行比(LPR)--用于推断克隆轨迹的计算机参数--破译转移灶的临床路径。结果仅肺转移灶:转移灶比例高,时间长,LPR 低,表明是平行传播。仅肝转移:罕见的转移性疾病,前驱时间短,LPR 高,提示线性传播。先肺后肝转移:罕见的单发转移灶,各器官之间的中位间隔为21个月,肺部和肝脏的LPR较高,提示向肺部的线性进展和向肝脏的平行扩散。先肝后肺转移:肝脏和肺脏的 LPR 值较低,器官之间的中位间隔为 16.5 个月,表明肝脏平行扩散,肝脏向肺部的线性扩散。同时发生的肝肺转移:罕见的单发转移以及相似和较高的LPRs提示同时向两个器官的线性进展。这些信息可能会对临床治疗产生潜在影响。

The varied clonal trajectory of liver and lung metastases of colorectal cancer

The varied clonal trajectory of liver and lung metastases of colorectal cancer

Background

The liver and lungs are the most common sites of colorectal cancer (CRC) metastases. Their involvement can take five different clinical scenarios: lung metastases only, liver metastases only, lung metastases before liver metastases, liver metastases before lung metastases and simultaneous lung and liver metastases. Using clinical and morphological data we studied the clonal trajectory of these scenarios.

Materials and methods

A total of 465 (CRC) patients with 7952 liver and 6406 lung metastases were evaluated. Metastases clinical route was deciphered from metastases number, timing, and linear/parallel ratio (LPR)- a computerized parameter used for deducing clonal trajectories. LPR of +1 suggest pure linear dissemination and −1 pure parallel.

Results

Lung-only metastases: high percentage of metachronous disease with a long lead time and a low LPR suggest parallel dissemination. Liver-only metastases: Rare metachronous disease with a short lead time, and a high LPR suggest linear spread. Lung-before-liver metastases: rare solitary metastasis, a median gap of 21 months between the organs, high lung and low liver LPRs suggest linear progression to the lungs and parallel dissemination to the liver. Liver-before-lung metastases: low liver and high lung LPRs and a median gap of 16.5 months between the organs suggest parallel dissemination to the liver and linear spread from the liver to the lungs. Simultaneous liver and lung metastases: rare solitary metastasis and similar and high LPRs suggest simultaneous linear progression to both organs.

Conclusions

CRC metastases have different dissemination trajectories in different clinical scenarios. This information can potentially impact on clinical management.
