Capecitabine Plus Bevacizumab for Cardiac Metastasis of Sigmoid Colon Cancer: Case Report and Literature Review

Evaluating combined bevacizumab and XELOX in advanced colorectal cancer: Serum markers carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 199 analysis

BACKGROUND

Colorectal cancer ranks third and second among common and fatal cancers. The treatment of metastatic colorectal cancer (mCRC) is generally based on XELOX in clinical practice, which includes capecitabine (CAP) and oxaliplatin. Serum tumor markers carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 125 and CA199 are prognostic factors for various tumors.

AIM

To investigate evaluating combined bevacizumab (BEV) and XELOX in advanced colorectal cancer: Serum markers CEA, CA125, CA199 analysis.

METHODS

In this retrospective study, a total of 94 elderly patients diagnosed with mCRC were recruited and subsequently categorized into two groups based on the distinct treatment modalities they received. The control group was treated with XELOX plus CAP (n = 47), while the observation group was treated with XELOX plus CAP and BEV (n = 47). Several indexes were assessed in both groups, including disease control rate (DCR), incidence of adverse effects, serum marker levels (CEA, CA125, and CA19) and progression-free survival (PFS).

RESULTS

After 9 wk of treatment, the serum levels of CEA, CA199 and CA125 in the observation group were significantly lower than those in the control group (P < 0.05). Moreover, the PFS of the observation group (9.12 ± 0.90 mo) was significantly longer than that of the control group (6.49 ± 0.64 mo). Meanwhile, there was no statistically significant difference in the incidence of adverse reactions and DCR between the two groups during maintenance therapy (P > 0.05).

CONCLUSION

On the basis of XELOX treatment, the combination of BEV and CAP can reduce serum tumor marker levels and prolong PFS in patients with mCRC.

Malignant Pericardial Effusion due to Colorectal Cancer in a Young Man

A 28-year-old man presented with sudden-onset right lower quadrant abdominal pain and shortness of breath at rest. On examination, he had tachycardia with distant heart sounds and right lower quadrant tenderness. A computed tomography scan showed segmental thickening of the proximal ascending colon and ileum with proximal cecal distension. Echocardiogram confirmed large pericardial effusion with impending tamponade. Video-assisted thoracoscopic surgery was performed for pericardial fluid drainage from a pericardial window. The mediastinal lymph node biopsy revealed metastatic adenocarcinoma cells. A colonoscopy showed a large polypoidal mass in the ascending colon with biopsy confirming poorly differentiated adenocarcinoma, thereby suggesting a possible lymphatic or hematogenous spread without liver or lung involvement.

Solitary Cardiac Metastasis from Colorectal Cancer: A Case Report

A 73-year-old woman with silent cardiac metastasis underwent high anterior resection for rectal cancer 3 years ago. Follow-up computed tomography showed a tumor in the right atrium. Partial vascular resection of the superior vena cava and right atrium was performed. Early postoperative recurrence occurred, and chemotherapy was unsuccessful. The patient died 7 months after surgery.
