Advances in genomic technologies have significantly improved the management of colorectal cancer (CRC). Several biomarkers have been identified in CRC that enable personalization in the use of biologic agents that have shown to enhance the clinical outcomes of patients. However, technologies used for their determination generate massive amounts of information that can be difficult for the clinician to interpret and use adequately.

We evaluated the efficacy and safety of trifluridine/tipiracil (TAS-102) plus bevacizumab in treating refractory metastatic colorectal cancer (mCRC) in a retrospective, observational study. Patients refractory or intolerant to standard therapies received TAS-102 (30-35 mg/m twice daily on days 1-5 and days 8-12 every 28 days) plus bevacizumab 5 mg/kg on days 1 and 15. Clinical and pathological characteristics, overall response rate (ORR), disease control rate (DCR), overall survival (OS) and progression-free survival (PFS) data were collected and analysed.

The general objective of this paper is to find out the extent to which decision making is based on knowledge of the most recent CT. Its specific objectives are to pinpoint difficulties with decision making based on the CT performed and find out the motivations patients and clinicians have when taking part in a CT.

The effect of FOLFIRI-aflibercept in routine clinical practice was evaluated.
Methods/patients: Overall survival (OS), progression-free survival (PFS), response and safety were analysed for 78 patients treated with FOLFIRI-aflibercept at six GITuD institutions.
Purpose There is a growing demand for BRCA1/ 2 mutation ( BRCAm) testing in patients with ovarian cancer; however, the limited number of genetic counselors presents a potential barrier. To facilitate more widespread BRCAm testing in ovarian cancer, pretest counseling by the oncology team could shorten testing turnaround times and ease the pressure on genetic counselors. Patients and Methods The prospective, observational Evaluating a Streamlined Onco-genetic BRCA Testing and Counseling Model Among Patients With Ovarian Cancer (ENGAGE) study evaluated a streamlined, oncologist-led BRCAm testing pathway.

There is lack of information about the efficacy and toxicity of chemotherapy and radiotherapy in the treatment of these patients. We present the case of a xeroderma pigmentosum patient with a neck node recurrence of a squamous cell skin carcinoma that achieved a good response and survival with cetuximab.

Specifically, BRCA1 interacts solely with the phosphorylated (inactive) form of ACCA (P-ACCA), and the formation of the BRCA1/P-ACCA complex interferes with ACCA activity by preventing P-ACCA dephosphorylation. One of the hallmarks of aggressive cancer cells is a high rate of energy-consuming anabolic processes driving the synthesis of lipids, proteins, and DNA (all of which are regulated by the energy status of the cell).
