The number of CA tandem repeats (CA)n in a highly polymorphic region of EGFR (epidermal growth factor receptor) intron 1 may affect gene transcription; the potential impact of allelic variants on the efficacy of cetuximab in metastatic colorectal cancer (mCRC) patients is debated for long. This study aimed at prospectively estimating the impact of EGFR intron 1 (CA)n variants on clinical outcome in KRAS exon 2 and BRAF wild-type chemo-refractory mCRC patients, receiving cetuximab and irinotecan. Variants presenting

Cohort study on the treatment of mutant metastatic colorectal cancer with integrated Chinese and western medicine.

Background: Patients with mutant metastatic colorectal cancer (mCRC) have a low incidence rate, poor biological activity, suboptimal response to conventional treatments, and a poor prognosis. In the previous cohort study on mCRC conducted by our team, it was observed that integrated Chinese and Western medicine treatment could significantly prolong the overall survival (OS) of patients with colorectal cancer. Therefore, we further explored the survival benefits in the population with mutant mCRC.

Background: Mucinous adenocarcinoma is a rare type of colorectal cancer (CRC) associated with poor prognosis, particularly when it includes signet ring cell components. Furthermore, its rate of microsatellite instability-high (MSI-H) is significantly higher compared to non-mucinous adenocarcinoma. Immunotherapy has emerged as the standard treatment for MSI-H metastatic CRC (mCRC).

Encorafenib + cetuximab (EC) is approved for previously treated BRAF V600E-mutant metastatic colorectal cancer (mCRC) based on the BEACON phase 3 study. Historically, first-line treatment of BRAF V600E-mutant mCRC with chemotherapy regimens has had limited efficacy. The phase 3 BREAKWATER study investigated EC+mFOLFOX6 versus standard of care (SOC) in patients with previously untreated BRAF V600E mCRC.

: Early-onset colorectal cancer (EOCRC) is more frequently characterized by poorly differentiated, aggressive tumors, often diagnosed at advanced stages, and associated with worse prognoses. Despite these differences, current treatment guidelines do not distinguish between EOCRC and late-onset colorectal cancer (LOCRC). Elevated expression of polo-like kinase 1 (PLK-1) has been linked to advanced disease stages and poorer treatment outcomes, including resistance to both chemotherapy and radiotherapy.

Background: Both aflibercept and bevacizumab-based regimens are available II-line treatment options for patients with metastatic colorectal cancer (mCRC). However, no head-to-head trials established the optimal anti-angiogenic strategy for this setting.
Methods: We launched a multicenter, retrospective, observational study to assess and compare clinical efficacy of II-line treatments for patients with mCRC.
