Introduction: There is very few data about the management of elderly patients with metastatic castration-resistant prostate cancer (mCRPC). The aim of this study was to analyze the management of patients aged 80 and over treated with docetaxel for a mCRPC.

Methods And Materials: Clinical and pathological characteristics of octogerians treated with docetaxel were collected retrospectively from 3 French centers from 2009 to 2019. Patient's outcome, treatments administered before and/or after docetaxel were also analyzed.

Results: Data of 89 patients could be analyzed. A total of 20.2 % of patients received the standard regimen and 79.8 % received an adapted one. Patients in the adapted group were significantly older than in standard one. Other patient's characteristics - including the geriatric scales - were similar. Dose reductions for toxicity were more frequent in the standard group (P=0.04). The median overall survival of the total population was 13.3 months. It was longer in the standard group than in the adapted group (26.1 months vs 12.4 months=0.01). In multivariate analysis, the type of docetaxel regimen (standard versus adapted) was an independent predictor of survival.

Conclusion: This study suggests the benefit of the standard management even in oldest patients. A geriatric evaluation should certainly be processed in patients with poor oncogeriatric scale in order to select the sub-population able to receive the full dose standard docetaxel regimen.

Does a homeopathic medicine reduce hot flushes induced by adjuvant endocrine therapy in localized breast cancer patients? A multicenter randomized placebo-controlled phase III trial.

Support Care Cancer 2019 May 7;27(5):1879-1889. Epub 2018 Sep 7.

Department of Medical Oncology, Centre Léon Bérard, 28 rue Laennec, 69373, Lyon Cedex 08, France.

Purpose: Endocrine therapy (ET) used to reduce the risk of recurrence in hormone receptor-expressing disease (75% of breast cancers) is associated with worsening of climacteric symptoms with a negative impact on quality of life (QoL). Homeopathy might allow a better management of hot flushes (HF).

Methods: In this multicenter randomized double-blind placebo-controlled phase III study ( NCT01246427), we enrolled ≥ 18 years old women with histologically proven non metastatic localized breast cancer, with Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) ≤ 1, treated for at least 1 month with adjuvant ET, and complaining about moderate to severe HF. Patients should not be scheduled for chemotherapy or radiotherapy, and had no associated pathology known to induce HF. After a 2- to 4-week placebo administration, we randomly assigned (1:1) patients with HFS ≥ 10 using an interactive web-based centralized platform to BRN-01 homeopathic medicine complex (Actheane®) in arm A or Placebo (Arm P). Randomization was stratified by adjuvant ET (taxoxifen/aromatase inhibitor) and recruiting site. HF scores (HFS) were calculated as the mean of HF frequencies before randomization, at 4, and at 8 weeks post-randomization (pre-, 4w,- and 8w-) weighted by a 4-level intensity scale. Primary endpoint was assessed at 4-week post-randomization, as the variation between pre- and 4w-HFS. Secondary endpoints included HFS variation between pre- and 8w-HFS, compliance and tolerance assessed 8 weeks after randomization, and QoL and satisfaction assessed at 4- and 8-week post-randomization.

Results: Two hundred ninety-nine patients were included, and 138 (46.2%) randomized (A, 65; P, 73). Median 4w-HFS absolute variation (A, - 2.9; P, - 2.5 points, p = 0.756) and relative decrease (A, - 17%; P, - 15%, p = 0.629) were not statistically different. However, 4w-HFS decreased for 46 (75%) in A vs 48 (68%) patients in P arm. 4w-QoL was stable or improved for respectively 43 (72%) vs 51 (74%) patients (p = 0.470).

Conclusions: The efficacy endpoint was not reached, and BRN-01 administration was not demonstrated as an efficient treatment to alleviate HF symptoms due to adjuvant ET in breast cancer patients. However, the study drug administration led to decreased HFS with a positive impact on QoL. Without any recommended treatment to treat or alleviate the HF-related disabling symptoms, Actheane® could be a promising option, providing an interesting support for better adherence to ET, thereby reducing the risk of recurrence with a good tolerance profile.

Bevacizumab plus microtubule targeting agents in heavily pre-treated ovarian cancer patients: a retrospective study.

Bull Cancer 2011 Oct;98(9):80-9

CHU Hautepierre, Department of Oncology & Hematology, Strasbourg, France.

OBJECTIVES. As vascular endothelial growth factor (VEGF) is expressed in ovarian cancer, we assessed the efficacy and safety of bevacizumab (a monoclonal antibody targeting VEGF) plus microtubule targeting agents for heavily pre-treated ovarian carcinoma patients. METHODS. We retrospectively reviewed 43 patients with recurrent epithelial ovarian carcinoma. Combined treatment included bevacizumab with paclitaxel in 32 (74%), docetaxel in 10 (23%), and vinorelbine in one (2.3%) patients, respectively. RESULTS. The median number of combined treatment was six cycles (range 1-29). On RECIST criteria, the objective response rate (ORR) was 40% (16% CR and 24% PR). Clinical benefit (complete response [CR] plus partial response [PR] and stable disease [SD] lasting ≥ 3 months) was 74% (CI95%: 46.7-77%). Median duration of treatment and overall survival were 3.9 months (range 0.2-14.4 months) and 20.1 months (CI95%: 13.8-20.1) respectively. No toxic death was reported. Grade 3-4 toxicity occurred in 30% of patients. Gastrointestinal perforations and fistula occurred in 3 (7%) and 6 (14%) patients, respectively. CONCLUSION. Although being active in terms of ORR, bevacizumab plus microtubule targeting agents - mainly taxanes - leads to a high rate of gastro-intestinal perforations and fistula in heavily pre-treated ovarian carcinoma patients.
