Italian results of the PRECONNECT study: safety and efficacy of trifluridine/tipiracil in metastatic colorectal cancer.

The international PRECONNECT Phase IIIb study demonstrated safety and efficacy of trifluridine/tipiracil in the management of patients with metastatic colorectal cancer. Post-hoc analyses in a national context are important because of the differences in disease management across countries. Post-hoc safety and efficacy analyses in the PRECONNECT Italian patient subset were conducted. Patients' quality of life was assessed from baseline to end of treatment. In Italy, 161 patients were enrolled. The median age was 64 years, with a performance status of 0-1. The most common hematological drug-related adverse events ≥grade 3 were neutropenia (41.0%) and anemia (13.7%). The median progression-free survival was reached at 3.0 months, with a disease control rate of 28.6%. The Quality of Life Questionnaire Core 30 score improved in 25.4% of the patients. Safety, efficacy and quality of life results confirmed trifluridine/tipiracil as a feasible and favorable treatment option for metastatic colorectal cancer patients.

Lay abstract PRECONNECT is an international study demonstrating the efficacy and tolerability of the drug combination trifluridine/tipiracil in adult patients with metastatic colorectal cancer treated in everyday clinical practice. For this publication, the authors conducted an analysis performed on the 161 Italian patients enrolled in this study. These kinds of analyses are important because of the differences that may arise across different countries. The most common contraindications were not dangerous to health. Furthermore, 3 months from beginning the medication, half of the patients did not show a worsening of the disease and quality of life during treatment was maintained. Clinical trial registration: NCT03306394 (ClinicalTrials.gov).

Final results of the SENECA (SEcond line NintEdanib in non-small cell lung CAncer) trial.

OBJECTIVES: Despite the scant docetaxel's tolerability, second-line association with nintedanib still represents a standard-of-care for non-squamous non-small cell lung cancer (nsNSCLC), giving to rapidly-progressing patients the greatest survival advantage. The SENECA trial is a phase IIb, open-label, study evaluating whether nintedanib/docetaxel can be equally effective and safe regardless docetaxel schedule. MATERIALS AND METHODS: Recurrent nsNSCLC patients were stratified into cohort 1 and 2, according to relapse-time (within or over 3 months) from end of first-line chemotherapy. They were treated with docetaxel (T1: 33 mg/mq on days 1 and 8 in a 21-days cycle; T2: 75 mg/mq q3wks) plus nintedanib, allowing maintenance in case of disease-control. Primary endpoint was progression-free survival (PFS) by investigator's assessment; secondary endpoints: overall survival (OS), safety and quality-of-life. RESULTS: Between January 2016-April 2018, 212 patients were evaluated: 30 resulted screening-failures, 12 were excluded for lack of compliance. According to investigator's choice, 85 patients received T1 docetaxel and 85 T2; 138 (81.2%) were stratified in C1, 32 (18.8%) in C2, with a median relapse-time of 0.54 and 9.29 months, respectively. Baseline characteristics were balanced between groups. After 35.5 months follow-up, no survival differences appear between cohorts and treatments; toxicity seems to be slightly higher in T2, especially for chemotherapy-related events. Perception of quality-of-life remains stable and docetaxel schedule doesn't modify patients' load. CONCLUSION: The SENECA trial confirms efficacy of second-line nintedanib/docetaxel for nsNSCLC, regardless time of recurrence and docetaxel schedule; higher toxicities for q3wks docetaxel, without alterations in quality-of-life, have been described, underling the possibility, adopting the weekly schedule, to maintain efficacy with better tolerability.

Osteonecrosis of the Jaw and Angiogenesis inhibitors: A Revival of a Rare but Serous Side Effect.

Osteonecrosis of the jaw (ONJ) is a rare treatment related side effect that was firstly described in 2002 through a case report in metastatic bone cancer patient treated with bisphosphonates (BPs) therapy. ONJ is defined as an eight weeks or longer clinical finding of exposed bone in the oral cavity without response to appropriate therapy. The diagnosis is mainly clinical but often requires a radiological confirmation with an orthopantomography. So it must be made by a dental specialist with sufficient experience on ONJ and requires a detailed anamnestic exploration of comorbidities and treatments history. In particular, ONJ affects a wide number of oncologic patients treated with BPs for bone metastatic cancers and, more recently, with anti-angiogenic drugs. The aim of this this paper is to describe diagnosis and classification of this rare but serious side effect and its pathophysiology. In particular, we provide a detailed description of clinical evidences upon the relationship between anti-angiogenic drugs and ONJ. Considering the evolving of cancer epidemiology with a greater number of cancer surviving patients, this side effect always deserves more attention. We conclude that ONJ must be always carefully investigated and prevented with a multidisciplinary approach involving oncologist, radiation oncologist and skilled dental practitioner when a cancer patient must begin a BP or an antiangiogenic treatment.
