Sidedness Matters: Surrogate Biomarkers Prognosticate Colorectal Cancer upon Anatomic Location

Conclusion.Our study indicates that right‐sided colorectal tumors may display worse prognosis compared with left‐sided tumors in MMR‐P stage II CRC. Primary tumor location may serve as a prognostic factor that should be taken into account for recurrence risk assessment and consideration of adjuvant treatment.Implications for Practice.Sidedness matters, even in stage II colorectal cancer (CRC). Using two previously established prognostic tools, the Oncotype DX assay and CDX2 expression, this study found that right‐sided tumors may display worse prognosis compared with left‐sided tumors in mismatch repair‐proficient stage II CRC. Therefore, primary tumor location should be taken into account for recurrence risk assessment and consideration of adjuvant treatment.

CONCLUSION: Parasitic diseases, such as those caused by Fasciola hepatica, should be kept in mind in the differential diagnosis of primary or metastatic liver tumors, such as colorectal cancer liver metastasis, in patients living in endemic areas. PMID: 31528248 [PubMed]

Authors: Gu J, Wang L, Li T, Tang S, Wang Y, Zhang W, Jiang X Abstract Oxaliplatin (OXA) is routinely used as the first‑line treatment for colorectal cancer (CRC). The addition of OXA to chemotherapy has significantly improved the prognosis of patients with CRC; however, some cases are resistant to OXA. The present study explored the influence of organic cation transporter 3 (OCT3) expression on the effects of OXA on CRC cell viability, and investigated the direct effects of OCT3 on viability, invasion and migration of CRC cells using MTT assay, wound healing assay, reverse transcription‑quantitative polymerase...

Extracts from two Italian grape varieties showed distinct anti-cancer activity in three different mesothelioma cell lines, according to a recent multicenter study in Naples, Italy. The in-vitro findings strongly suggest potential of a novel, nonconventional mesothelioma treatment advancement in the future for this aggressive, difficult-to-treat cancer. Previous laboratory studies have shown a negative impact of grape-seed extracts on breast, colon and skin cancer cells, but this was the first using multiple human mesothelioma cell lines. “Our study on mesothelioma seems very promising, but it is a preliminary analysi...

This study aims to examine trends of patients with rectal cancer who are receiving care at large hospitals, to determine the patient characteristics associated with treatment at large hospitals, and to assess the relationships between treatment at large hospitals and guideline-recommended therapy. DESIGN: This study was a retrospective cohort analysis to assess trends in rectal cancer treatment. SETTINGS: Data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results Patterns of Care studies were used. PATIENTS: The study population consisted of adults diagnosed with stages II/III rect...

CONCLUSION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for isolated low-volume colorectal peritoneal metastases are not safe and effective, with low morbidity. It offers selected patients a highly favorable overall and relapse-free survival.

Shigeru Okada John J. Kopchick Growth hormone (GH) facilitates therapy resistance in the cancers of breast, colon, endometrium, and melanoma. The GH-stimulated pathways responsible for this resistance were identified as suppression of apoptosis, induction of epithelial-to-mesenchymal transition (EMT), and upregulated drug efflux by increased expression of ATP-binding cassette containing multidrug efflux pumps (ABC-transporters). In extremely drug-resistant melanoma, ABC-transporters have also been reported to mediate drug sequestration in intracellular melanosomes, thereby reducing drug efficacy. Melanocyte-inducing...

CONCLUSIONS: Age was the strongest predictor of chemotherapy underuse, irrespective of comorbidities and even in patients without comorbidities. Such underuse due just to older age in otherwise healthy patients deserves increased attention in clinical practice to ensure that elderly patients also get the best possible care. Patients' refusal as the most frequent reason for chemotherapy nonreceipt also warrants further investigation to exclude misinformation as underlying cause. PMID: 31487678 [PubMed - in process]

AbstractThe application of robotic technology allows for the performance of multi-organ liver resections by multidisciplinary teams in a minimally invasive manner. Their technique and outcomes are not established. Herein we describe our technique with robotic liver surgery combined with colon, pancreas and urologic resections. Our patients are an 84-year-old (yo) female (Body Mass Index, BMI: 25) with a recently diagnosed right colon adenocarcinoma and two synchronous liver metastases at segments 5 and 6, a 75-year-old female (BMI: 50.4) with a history of right renal cell cancer status post (s/p) right robotic radical neph...
