Sexual quality of life assessment in young women with breast cancer during adjuvant endocrine therapy and patient-reported supportive measures.

PURPOSE: Sexual quality of life (QoL) is affected during and after breast cancer (BC) treatment. The purpose was to investigate sexual and global QoL and patient-reported measures to address this issue in young women (< 51 years) with BC after the acute treatment phase, during adjuvant endocrine therapy. METHODS: Three EORTC questionnaires and an additional specific questionnaire, developed for the study, were used to assess sexual and global QoL and patient-reported supportive measures in BC patients who had received their endocrine therapy for at least 24 months. Among the 54 eligible patients, 45 (83%) agreed to participate in the study. RESULTS: We showed a deterioration in sexual QoL and poor communication with healthcare professionals. Most patients (88.9%) declared that it was important that sexuality should be discussed with caregivers and that the partner should also be involved. Most patients (60%) had taken at least one action to overcome their sexual problems. Most of these interventions (63%) originated from the patient herself. CONCLUSIONS: Sexual QoL is a major issue in young BC patients and is poorly addressed by healthcare professionals. Most of the supportive methods used by the patients to overcome these side effects were on their own initiative. Communication and counseling on sexuality by healthcare professionals need to be improved during BC treatment. Patients suggested supportive measures they would find useful and appropriate to develop in the clinic. The final goal is to improve the sexual QoL of BC patients with the appropriate intervention and support.

Regorafenib plus FOLFIRINOX as first-line treatment for patients with RAS-mutant metastatic colorectal cancer (FOLFIRINOX-R trial): a dose-escalation study.

PURPOSE: The combination of bevacizumab and FOLFIRINOX is used in patients with RAS-mutant metastatic colorectal cancer (RASm-mCRC). Regorafenib, an oral multi-tyrosine kinase inhibitor, has antiangiogenic properties, cytostatic effects and also true cytotoxic effects, unlike bevacizumab. The aim of this study was to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of the regorafenib-FOLFIRINOX combination in patients with RASm-mCRC. METHODS: The FOLFIRINOX-R trial was a phase 1/2 study where the dose-escalation part (3 + 3 design with three dose levels, DLs) was completed before its early termination. FOLFIRINOX (14-day cycle) included oxaliplatin (standard dose), folinic acid, fluorouracil and irinotecan (150 or 180 mg/m²). Regorafenib (120 or 160 mg daily) was given from day 4 to day 10 of each cycle. Dose-limiting toxicity (DLT) was studied in the first three cycles. Eligibility criteria included ECOG performance status ≤ 1 and not previously treated RASm-mCRC. RESULTS: Thirteen patients (median age: 65 years; min-max: 40-76) were enrolled. DLT could not be evaluated in one patient (DL3) due to poor observance. The median treatment duration and median follow-up were 6.2 (min-max: 2.3-10) and 13.4 (min-max: 3.8-18.0) months, respectively. Dose was modified in 12/13 (92%) patients. One grade 3 hypokalemia occurred at DL2. MTD was not reached at DL3. Grade 3 diarrhea was recorded in 7/13 patients (13 events) equally distributed in all DLs. CONCLUSION: The RP2D for this regorafenib-FFX combination could not be determined due to a high prevalence of grade 3 diarrhea related to treatment as advised by our Independent Data Monitoring Committee.
