Effectiveness of increasing the scalp cooling duration to prevent alopecia during adjuvant chemotherapy for breast cancer: a randomized pilot study.

PURPOSE: Alopecia is a common side-effect of chemotherapy and can be extremely distressing to patients. Scalp cooling can be used to reduce hair loss, but the optimal duration of cooling remains unclear. Our aim was to determine whether increasing the duration of scalp cooling improves hair preservation. METHODS: Patients with HER2-negative, non-metastatic, breast cancer received scalp cooling during adjuvant chemotherapy: three cycles of epirubicin/cyclophosphamide (EC) followed by three cycles of paclitaxel. The patients were randomly assigned to two groups. Group A (n=18) wore a Paxman cooling cap during each infusion and for 30 min post-infusion while Group B (n=19) wore the cap from 30 min before to 2 h after each infusion. All patients were asked to complete a questionnaire recording hair loss/regrowth, adverse events, and quality of life. Success of treatment was defined as <50% hair loss. RESULTS: The success rates after each of the three cycles did not differ significantly between the two groups (EC: Group A: 40%, Group B: 44%; paclitaxel: Group A: 50%, Group B: 36%; p>0.05). Hair regrowth was significantly higher in Group B at the 8-week follow-up, but not at the 6-month follow-up. Head discomfort affected more patients in Group B than in Group A during the first session (94% vs. 62%, respectively; p=0.039). CONCLUSION: Long duration scalp cooling during chemotherapy might increase patients' discomfort and does not appear to improve hair preservation.

FOLFIRI Plus Durvalumab With or Without Tremelimumab in Second-Line Treatment of Advanced Gastric or Gastroesophageal Junction Adenocarcinoma: The PRODIGE 59-FFCD 1707-DURIGAST Randomized Clinical Trial.

Importance: Efficacy of second-line chemotherapy in advanced gastric or gastrooesphageal junction (GEJ) adenocarcinoma remains limited. Ojectives: To determine the efficacy of 1 or 2 immune checkpoint inhibitors combined with FOLFIRI (leucovorin [folinic acid], fluorouracil, and irinotecan) in the treatment of advanced gastric/GEJ adenocarcinoma. Design, Setting, and Participants: The PRODIGE 59-FFCD 1707-DURIGAST trial is a randomized, multicenter, noncomparative, phase 2 trial, conducted from August 27, 2020, and June 4, 2021, at 37 centers in France that included patients with advanced gastric/GEJ adenocarcinoma who had disease progression after platinum-based first-line chemotherapy. Intervention: Patients were randomized to receive FOLFIRI plus durvalumab (anti-programmed cell death 1 [PD-L1]) (FD arm) or FOLFIRI plus durvalumab and tremelimumab (anti-cytotoxic T-lymphocyte associated protein 4 [CTLA-4]) (FDT arm). The efficacy analyses used a clinical cutoff date of January 9, 2023. Main outcome and Measures: The primary end point was progression-free survival (PFS) at 4 months according to RECIST 1.1 criteria evaluated by investigators. Results: Overall, between August 27, 2020, and June 4, 2021, 96 patients were randomized (48 in each arm). The median age was 59.7 years, 28 patients (30.4%) were women and 49 (53.3%) had GEJ tumors. Four month PFS was 44.7% (90% CI, 32.3-57.7) and 55.6% (90% CI, 42.3-68.3) in the FD and FDT arms, respectively. The primary end point was not met. Median PFS was 3.8 and 5.4 months, objective response rates were 34.7% and 37.7%, and median overall survival was 13.2 and 9.5 months in the FD and FDT arms, respectively. Disease control beyond 1 year was 14.9% in the FD arm and 24.4% in the FDT arm. Grade 3 to 4 treatment-related adverse events were observed in 22 (47.8%) patients in each arm. A combined positive score (CPS) PD-L1 of 5 or higher was observed in 18 tumors (34.0%) and a tumor proportion score (TPS) PD-L1 of 1% or higher in 13 tumors (24.5%). Median PFS according to CPS PD-L1 was similar (3.6 months for PD-L1 CPS ≥5 vs 5.4 months for PD-L1 CPS <5) by contrast for TPS PD-L1 (6.0 months for PD-L1 TPS ≥1% vs 3.8 months for PD-L1 TPS <1%). Conclusions and Relevance: Combination of immune checkpoint inhibitors with FOLFIRI in second-line treatment for advanced gastric/GEJ adenocarcinoma showed an acceptable safety profile but antitumor activity only in a subgroup of patients.

PROPERTY: study protocol for a randomized, double-blind, multicenter placebo-controlled trial assessing neurotoxicity in patients with metastatic gastrointestinal cancer taking PHYCOCARE® during oxaliplatin-based chemotherapy.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common adverse effects of antineoplastic agents, ranging in prevalence from 19% to over 85%. Clinically, CIPN is a predominantly sensory neuropathy that may be accompanied by motor and autonomic changes of varying intensity and duration. The high prevalence of CIPN among cancer patients makes it a major problem for both patients and survivors, as well as for their health care providers, especially because there is currently no single effective method of preventing CIPN; moreover, the options for treating this syndrome are very limited. Phycocyanin, a biliprotein pigment and an important constituent of the blue-green algae Spirulina platensis, has been reported to possess significant antioxidant and radical-scavenging properties, offering protection against oxidative stress, which is one of the hypothetic mechanisms, between others, of CIPN occurrence. METHODS: Our hypothesis is that phycocyanin may give protection against oxaliplatin-induced neuropathy in the treatment of gastrointestinal cancers. Our trial will be a randomized double-blind placebo-controlled study with 110 randomized patients suffering from metastatic gastrointestinal adenocarcinoma including esogastric, colorectal, and pancreatic cancers. Patients are being followed up in the gastroenterology or oncology departments of seven French hospitals. DISCUSSION: Due to the neuropathy, patients need to avoid injury by paying careful attention to home safety; patients' physicians often prescribe over-the-counter pain medications. If validated, our hypothesis should help to limit neurotoxicity without the need to discontinue chemotherapy. TRIAL REGISTRATION: ClinicalTrials.gov NCT05025826. First published on August 27, 2021.
