Abstract PDF PubReader ePub: The increasing global prevalence of obesity and metabolic syndrome (MetS) is strongly associated with the incidence of colorectal cancer (CRC). Obesity and MetS detrimentally impact the treatment outcomes of CRC and share similar mechanisms that contribute to the development of CRC. Increased insulin resistance in patients with obesity is linked to CRC, and altered levels of sex hormones and adipokines affect cell growth and inflammation. Obesity and MetS also alter the gut microbiome. Bile acids, which are crucial for lipid metabolism, are elevated in patients with obesity. Moreover, specific bile acids are associated with colonic damage, inflammation, and the development of CRC. Obesity and MetS increase the risk of postoperative complications and affect the response to chemotherapy. The promotion of weight loss and the resolution of MetS can reduce the occurrence of CRC and increase treatment efficacy. Therefore, it is imperative to implement appropriate management strategies to address obesity and MetS with the aim of improving the prognosis and reducing the incidence of CRC. Moreover, additional research should be conducted to determine the optimal timing for tailored CRC screening in patients with obesity or MetS. In this review, we explore the impact of obesity and MetS on the development of CRC and examine potential strategies to mitigate CRC risk in individuals with obesity and MetS.

Abstract PDF PubReader ePub: Percutaneous sacroplasty is mainly used as an intervention for pain associated with sacral insufficiency fractures or sacral metastatic tumors. However, sacroplasty for managing the pain associated with direct sacral invasion of rectal cancer has been rarely reported. We present a case of a 74-year-old patient who underwent sacroplasty via the interpedicular approach under fluoroscopic guidance to relieve pain resulting from direct tumor invasion into the S3 body. After the procedure, the patient experienced immediate pain relief and did not feel worse pain with ambulation. Aside from peritumoral vascular leakage, no other significant complications occurred immediately post-procedure. Our results suggest that fluoroscopically guided interpedicular sacroplasty is a safe and effective option for relieving the pain associated with direct sacral invasion by rectal cancer.

Drug-induced immune-mediated thrombocytopenia due to bevacizumab-FOLFOX therapy: a case report: Minna Kim, Jong Hoon Lee, Jong Yoon Lee; Kosin Med J. 2023;38(4):300-306. Published online July 28, 2023; DOI: https://doi.org/10.7180/kmj.23.121

Abstract PDF PubReader ePub: Drug-induced immune thrombocytopenia (DITP) is a very rare disease, with an estimated annual incidence of 10 cases per million. Oxaliplatin and irinotecan are widely used as chemotherapy for high-risk stage II and III colorectal cancer, and DITP has been reported to occur in patients using those agents. To treat unresectable metastatic colorectal cancer, bevacizumab is used in combination with oxaliplatin or irinotecan, and there have been a few reports of DITP cases in patients receiving that regimen. In this report, we describe a 68-year-old male patient with metastatic colon cancer (KRAS mutant type) to the liver and lung who developed acute immune-mediated thrombocytopenia due to bevacizumab-FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) therapy. During treatment, he showed purpura in his lower extremities on 21st cycle day 2. Lab work revealed a platelet count of less than 2,000/mL, reflecting a decrease from 135,000/mL at the start of the cycle 1 day prior. He did not have any other types of cytopenia or significant changes in laboratory findings. We diagnosed DITP due to bevacizumab-FOLFOX, and the patient did not show isolated thrombocytopenia after switching to Ziv-aflibercept-FOLFIRI (5-fluorouracil, leucovorin, and irinotecan).

Background
Colorectal cancer is one of the most common cancers worldwide. Colorectal cancer that has recurred and metastasized to other organs also has a very poor prognosis. According to recent studies, the long interspersed element-1 (LINE-1) retrotransposon open reading frame (ORF) is located in the intron of the c-Met proto-oncogene, which is involved in cancer progression and metastasis, and regulates its expression. However, no study has compared the expression patterns of LINE-1 ORF1 and c-Met, which are closely related to cancer progression and metastasis, and their correlation in primary and recurrent cancers.
Methods
In the present study, we compared the expression patterns of LINE-1 ORF1 and c-Met in both primary and recurrent colorectal cancer tissues from 10 patients. Expression patterns and correlations between LINE-1 ORF1 and c-Met proto-oncogene proteins were analyzed by immunofluorescence staining using both LINE-1 ORF1 and c-Met antibodies.
Results
The expression patterns of LINE-1 ORF1 and c-Met showed significant individual differences, and the expression of both proteins was correlated in all colorectal cancer patients. However, the expression levels of LINE-1 ORF1 and c-Met were not significantly different between primary and recurrent colorectal cancers.
Conclusions
The protein expression levels of LINE-1 ORF1 and c-Met were correlated, but did not change significantly in cases of recurrent colorectal cancer in the same patient.
