Abstract
BACKGROUND

Multiple primary carcinomas (MPCs) are defined as two or more independent primary cancers that occur simultaneously or sequentially in the same individual. Synchronous MPCs are rarer than solitary cancers or metachronous MPCs. Accurate diagnoses of synchronous MPCs and the choice of treatment are critical for successful outcomes in these cases.

CASE SUMMARY

A 64-year-old patient presented with dysphagia, without obvious cause. A diagnosis of synchronous esophageal squamous cell carcinoma and colon adenocarcinoma with liver metastasis was confirmed based on examination and laboratory results. After multi-disciplinary consultations, combination chemotherapy (a 3-wk cycle with oxaliplatin 212 mg administered on day 1 and capecitabine 1.5 g twice daily on days 1-14) and esophageal cancer radiotherapy were initiated. Based on the results of genetic testing, we switched to a regimen of leucovorin + fluorouracil + oxaliplatin and cetuximab regimen for 8 cycles. Subsequently, capecitabine and bevacizumab were administered until the most recent follow-up, at which the tumor remained stable.

CONCLUSION

Successful cetuximab chemotherapy treatment provides a reference for the non-operative and homogeneous treatment of different pathological types of synchronous MCPs.

Core Tip: We report a case of a 64-year-old patient diagnosed with synchronous esophageal squamous cell carcinoma and colon adenocarcinoma with liver metastasis. After multi-disciplinary consultations, oxaliplatin + capecitabine chemotherapy and esophageal cancer radiotherapy were initiated. Based on genetic testing, treatment was switched to a regimen of leucovorin + fluorouracil + oxaliplatin and cetuximab for 8 cycles. Subsequently, capecitabine and bevacizumab were administered, and the tumor was stable at the most recent follow-up. This case demonstrates successful treatment of dual primary digestive tract tumors of differing pathological types using the same regimen, which supports non-surgical, simultaneous treatment for synchronous multiple primary cancers.
