Article Abstract
Introduction: Colorectal cancer (CRC) is a clinically heterogeneous disease, which necessitates a variety of treatments and leads to different outcomes. Only some CRC patients will benefit from neoadjuvant chemotherapy (NACT).
Objectives: An accurate prediction of response to NACT in CRC patients would greatly facilitate optimal personalized management, which could improve their long-term survival and clinical outcomes.
Methods: In this study, plasma metabolite profiling was performed to identify potential biomarker candidates that can predict response to NACT for CRC. Metabolic profiles of plasma from non-response (n = 30) and response (n = 27) patients to NACT were studied using UHPLC-quadruple time-of-flight)/mass spectrometry analyses and statistical analysis methods.
Results: The concentrations of nine metabolites were significantly different when comparing response to NACT. The area under the receiver operating characteristic curve value of the potential biomarkers was up to 0.83 discriminating the non-response and response group to NACT, superior to the clinical parameters (carcinoembryonic antigen and carbohydrate antigen 199).
Conclusion: These results show promise for larger studies that could result in more personalized treatment protocols for CRC patients.

Background: People living with HIV(PLWH) are a high-risk population for cancer. We conducted a pioneering study on the gut microbiota of PLWH with various types of cancer, revealing key microbiota.
Methods: We collected stool samples from 54 PLWH who have cancer (PLWH-C), including Kaposi's sarcoma (KS, n=7), lymphoma (L, n=22), lung cancer (LC, n=12), and colorectal cancer (CRC, n=13), 55 PLWH who do not have cancer (PLWH-NC), and 49 people living without HIV (Ctrl).
Utilizing tumor deposit count as a stratification criterion in revising TNM staging system for patients with colorectal cancer: a nomogram review study.

Background: Tumor deposit (TD) is an independent risk factor associated with recurrence or metastasis for patients with colorectal cancer (CRC). The scenario in which both TD and lymph node metastasis (LNM) are positive is not clearly illustrated by the current TNM staging system. Simply treating one TD as one or two LNMs by a weighting factor is inappropriate.

Introduction: Metastatic colorectal cancer (mCRC) exhibits significant heterogeneity in molecular profiles, influencing treatment response and patient outcomes. Mutations in v-raf murine sarcoma viral oncogene homolog B1 () and rat sarcoma () family genes are commonly observed in mCRC. Though originally thought to be mutually exclusive, recent data have shown that patients may present with concomitant and mutations, posing unique challenges and implications for clinical management.

Introduction: We identified potential approaches to address barriers to colorectal cancer (CRC) screening in rural communities of award recipients from the Centers for Disease Control and Prevention's Colorectal Cancer Control Program (CRCCP).
Methods: Nine program managers and directors discussed approaches to address barriers to CRC screening. The programs served areas with rural communities and tribal reservations.

NUT carcinoma is a rare and highly aggressive malignancy characterized by rapid progression, resistance to conventional therapies, and an extremely poor prognosis. This report presents a 36-year-old patient with stage IIIB primary pulmonary NUT carcinoma who achieved remarkable clinical outcomes with NHWD-870 monotherapy, a novel BET inhibitor. After just 1 month of treatment, imaging revealed a partial response, and a complete response was achieved within 5 months.
