RESUMO
INTRODUCTION: The subcutaneous (H-SC) formulation of trastuzumab was demonstrated to be as effective and safe as intravenous (H-IV) and highly preferred by patients in early breast cancer. The present randomized MetaspHER trial (NCT01810393) has been the first study assessing patient's preference in metastatic setting and we report the final analysis with long term follow-up. METHODS: Patients with HER2-positive metastatic breast cancer who completed a first line chemotherapy with trastuzumab and achieved a long terms response lasting more than 3 years were randomized to receive 3 cycles of 600 mg fixed-dose H-SC, followed by 3 cycles of standard H-IV, or the reverse sequence. The primary endpoint was overall preference for H-SC or H-IV at cycle 6 and was previously reported. Secondary endpoints included safety over 1 year of treatment and with 4 additional years follow up. Overall survival (OS) and progression free survival (PFS) were assessed in this final analysis. RESULTS: A total of 113 patients were randomized and treated and the median follow-up duration was 45.4 months (range: 0.8-48.8). After the cross over period all patients excepted 2 pursued the H-SC. During the 18 cycles overall treatment period, at least 1 adverse event (AE), 1 AE of grade ≥3, and 1 serious adverse events (SAE) were respectively reported among 104 patients (92.0%), 23 patients (20.4%), and 16 patients (14.2%), respectively. Also, 10 patients (8.9%) experienced at least 1 cardiac event, including 4 patients (3.5%) with ejection fraction decreased. Beyond cycle 18 no significant additional safety concern emerged. PFS and OS rates at months 42 were 74.8% (64.7%-82.4%) and 94.9% (88.2%-97.9%), respectively. No factor appeared related to the survival outcome excepted the complete response status at baseline. CONCLUSION: The safety was consistent with the known H-IV and H-SC profiles without any safety concern raised over a prolonged exposure to H-SC.
RESUMO
Background: Hepatic arterial infusion (HAI) of chemotherapy is an option for the treatment of patients with liver metastases from colorectal cancer (LMCRC). Though HAI with oxaliplatin (HAI-Ox) is generally used, intravenous (IV) 5-fluoro-uracil (5FU)-oxaliplatin-irinotecan HAI (HAI-Folfirinox) is feasible and leads to curative-intent surgery in 30% of pretreated patients. We compared the efficacy and safety of HAI-Ox and HAI-Folfirinox. Methods: Patients who underwent HAI chemotherapy for LMCRC were retrospectively included from 2008 to 2019 from six French expert centers. Results: Data were collected from 273 previously treated patients with LMCRC. Patients received HAI-Folfirinox (n = 52) or HAI-Ox (n = 221) combined with IV chemotherapy. The objective response rate (ORR) was 43.2% in patients with HAI-Folfirinox and 45.9% (ns) in patients with HAI-Ox. Median overall survival (OS) was 17 months (95% CI: 15-32.3) with HAI-Folfirinox and 26.2 months (95% CI: 19.4-34.4; p = 0.1) with HAI-Ox. Median progression-free survival (PFS) was 7.9 months (95% CI: 4.9-10.3) with HAI-Folfirinox and 6.4 months (95% CI: 6.0-7.7; p = 0.6) with HAI-Ox. The secondary liver resection rate was 35.6% with HAI-Folfirinox and 16.7% with HAI-Ox (p = 0.007). Grade 2 and above toxicities were significantly more frequent with HAI-Folfirinox. In the global population, only 2 factors were prognostic for OS in multivariable analyses: liver-only disease [hazard ratio (HR): 0.4; 95% CI 0.20-0.83; p = 0.013] and local complications of the catheter (HR: 3.8; 95% CI 1.6-9.0; p = 0.002). Conclusion: Hepatic arterial infusion results in high response rates, secondary resections, and long survival in pretreated patients with LMCRC.
RESUMO
To facilitate multidisciplinary team meetings' (MTM) management, the cancer research networks developed a communicating file. The Midi-Pyrénées region includes the Oncomip network and a cancer registry in the department of Tarn. Their collaboration allows the assessment of the care given to patients. The objectives of this study were to measure the completeness of the presentation to MTM of patients and its determinants (age and prognostic factors), and to study the quality of MTM for breast cancer diagnosed in the Tarn in 2007. A track of presentation to MTM chronologically conform was found in 70.5%. The completeness of presentation seemed lower for the oldest women and the parameters conditioning the decision of a non-surgical treatment were associated with a more frequent presentation to MTM. The quorum was respected for 53.9% of cases presented before all treatment and for 71.3% of cases presented after surgery. The partnership, which exists between the Tarn cancer registry and the Oncomip network, makes the realization of similar studies in population with other type of cancer possible.
