The Management of a Comprehensive Cancer Center during the First Six Months of the COVID-19 Pandemic in the South of France: Lessons from the Paoli-Calmettes Institute's Experience.

During the COVID-19 pandemic, it was rapidly established that cancer patients have an increased risk of developing severe forms of the 2019 coronavirus disease (COVID-19) due to a backlog of cancer diagnostics and immunosuppressive treatments. Cancer centers had to quickly adapt to continue cancer therapies despite the high infection risks and major disruptions in the French healthcare system. We described and analyzed the impact of the pandemic in our institution: management adjustments, COVID-19 infection rates in patients and staff, and impacts on clinical activities and finances during the first wave of the pandemic from March to September 2020. We also compared the results to the clinical activity data from preceding periods. A crisis unit was rapidly created that met 27 times over 66 days, generating numerous changes in hospital protocol. While our area was devastated by the pandemic, the infection rate of our staff and patients remained low (less than 1.5% of all employees). However, the lockdown period was accompanied with a reduction of most clinical activities, leading to decreases of 43%, 36%, 36%, 1%, and 10% in surgery, endoscopy, radiotherapy, and in- and out-patient chemotherapy sessions, respectively, with substantial financial loss. Our report highlights the need for the rapid creation, implementation, and adaptation of new protocols during a pandemic's evolution to prevent disease transmission. Lessons from this situation should provide motivation to better prepare for/limit the dismantling of cancer therapies that can dramatically impact patient care and have deleterious consequences on an institution's financial situation.

PIKHER2: A phase IB study evaluating buparlisib in combination with lapatinib in trastuzumab-resistant HER2-positive advanced breast cancer.

BACKGROUND: Phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin pathway is frequently activated in HER2-positive breast cancer and may play a major role in resistance to trastuzumab. Buparlisib is a pan-class-I PI3K inhibitor with potent and selective activity against wild-type and mutant PI3K p110 isoforms. PATIENTS AND METHODS: PIKHER2 phase IB study aimed primarily to determine a maximum tolerated dose (MTD) and propose a recommended phase II dose (RP2D) for buparlisib in combination with lapatinib in HER2-positive, trastuzumab-resistant, advanced breast cancer. Oral buparlisib (40, 60 or 80 mg) and lapatinib (750, 1000 or 1250 mg) were administered daily. A modified continuous reassessment method using an adaptive Bayesian model guided the dose escalation of both agents. Secondary end-points included antitumour activity and pharmacokinetic (PK) assessments. RESULTS: A total of 24 patients were treated across five dose levels. Dose-limiting toxicities included transaminases elevation, vomiting, stomatitis, hyperglycemia and diarrhoea. MTD was declared at buparlisib 80 mg/d + lapatinib 1250 mg/d, but toxicities and early treatment discontinuation rate beyond cycle 1 led to select buparlisib 80 mg + lapatinib 1000 mg/d as the RP2D. Main drug-related adverse events included diarrhoea, nausea, skin rash, asthenia, depression, anxiety and transaminases increase. There was no significant evidence for drug-drug PK interaction. Disease control rate was 79% [95% confidence interval [CI] 57-92%], one patient obtained a complete remission, and six additional patients experienced stable disease for ≥ 24 weeks (clinical benefit rate of 29% [95% CI 12-51%]). CONCLUSION: Combining buparlisib and lapatinib in HER2-positive trastuzumab-resistant advanced breast cancer was feasible. Preliminary evidence of antitumour activity was observed in this heavily pre-treated population. TRIAL REGISTRATION ID: NCT01589861.

Full access to medical records does not modify anxiety in cancer patients: results of a randomized study.

BACKGROUND: Information is crucial for increasing the patients' empowerment and autonomy in relevant decision-making processes, especially in malignant diseases. However, the extent to which information should be delivered is debated. The objective of this study was to assess the impact of providing systematic full access (SFA) to the medical record on anxiety, quality of life, and satisfaction. METHODS: Patients with newly diagnosed breast cancer, colon cancer, or lymphoma who had received adjuvant chemotherapy in an outpatient setting were included in a randomized controlled trial comparing those who requested access (RA) and those who provided SFA to the medical record. Anxiety was assessed using the Spielberger State-Trait Anxiety Inventory before, during, and at the end of treatment. Quality of life was evaluated using the European Organization for Research and Cancer quality-of-life questionnaire (EORTC QLQ-C30) before and at the end of treatment. Patients' satisfaction and perception of the organized medical record (OMR) were evaluated using a specifically designed questionnaire at the end of treatment. RESULTS: Most patients (98%) who had the opportunity to obtain the OMR chose to do so. Anxiety levels did not increase in the SFA arm, although they did not differ significantly compared with anxiety levels in the RA arm. The patients who had full access to their medical record were more satisfied with information (odds ratio, 1.68; 95% confidence interval, 0.98-2.9) and felt sufficiently informed more often (odds ratio, 1.86; 95% confidence interval, 1.08-3.19), but the differences were not statistically significant at the 5% level. CONCLUSIONS: Allowing full access to personal medical records increased satisfaction without increasing anxiety in patients with newly diagnosed cancer.

Breast cancer guidelines--Physicians' intentions and behaviors.

Guidelines are written to define what a physician should do, and networks set up to provide every patient with good practice. However, is willingness to treat according norms enough to actually implement it? Between 1997 and 2003, 4,533 women with invasive, noninflammatory, nonmetastatic breast cancer have been treated within the framework of a regional network (R2C). The rate of implementation of 5 consensual norms was assessed. The rate of "abnormal" management regarding surgical re-excision for inadequate margin was found to be 12.6%. The main explanatory variable was patient age >70 years (OR = 4.05). For nodal exploration, the sampling quality threshold was set at 10. Mean rate of lack of compliance was 25.2%. The 2 main explicative factors were surgeon's experience and women's age. The observed rate of "insufficient" irradiation dose was 18.2%. The main explanatory variables were age (with a gradient) and a negative nodal status. Concerning adjuvant chemotherapy, the rate of no treatment (despite consensual indication) was 16.0%. Again, the main explicative factor was age (with a gradient). Women's age appears to be a major explanatory variable predicting lack of physician's compliance with consensual norms. Besides the age of the women, a "better" prognosis (negative nodal status and pT < or = 20 mn) is often associated with lack of compliance. It is not clear, however, if it's the rules that do not fit the clinical situation of aging patients or the physicians who are not aware of the benefit of consensual disease management for aging patients.

Gene expression profiling for molecular characterization of inflammatory breast cancer and prediction of response to chemotherapy.

Inflammatory breast cancer (IBC) is a rare but aggressive form of breast cancer with a 5-year survival limited to approximately 40%. Diagnosis, based on clinical and/or pathological criteria, may be difficult. Optimal systemic neoadjuvant therapy and accurate predictors of pathological response have yet to be defined for increasing response rate and survival. Using DNA microarrrays containing approximately 8,000 genes, we profiled breast cancer samples from 81 patients, including 37 with IBC and 44 with noninflammatory breast cancer (NIBC). Global unsupervised hierarchical clustering was able to some extent to distinguish IBC and NIBC cases and revealed subclasses of IBC. Supervised analysis identified a 109-gene set the expression of which discriminated IBC from NIBC samples. This molecular signature was validated in an independent series of 26 samples, with an overall performance accuracy of 85%. Discriminator genes were associated with various cellular processes possibly related to the aggressiveness of IBC, including signal transduction, cell motility, adhesion, and angiogenesis. A similar approach, with leave-one-out cross-validation, identified an 85-gene set that divided IBC patients with significantly different pathological complete response rate (70% in one group and 0% in the other group). These results show the potential of gene expression profiling to contribute to a better understanding of IBC, and to provide new diagnostic and predictive factors for IBC, as well as for potential therapeutic targets.

Weekly administration of docetaxel for symptomatic metastatic hormone-refractory prostate carcinoma.

BACKGROUND: The current Phase II study investigated the clinical benefit, impact on quality of life (QOL), and tolerability of weekly docetaxel in symptomatic patients with metastatic hormone-refractory prostate carcinoma (HRPC). METHODS: Patients received weekly docetaxel 35 mg/m(2) intravenously for 6 consecutive weeks followed by a 2-week rest repeatedly for a maximum of 24 weeks of treatment. Clinical benefit evaluations, based on Karnofsky performance status (KPS) and pain, were assessed weekly during therapy. A clinical benefit response was defined as a sustained (> or = 4-week) improvement in at least one of these parameters without worsening in the other. Patient-assessed QOL (using the European Organization for Research and Treatment of Cancer QLQ-C30), changes in prostate-specific antigen (PSA) levels, tumoral response, and toxicity also were evaluated. RESULTS: Thirty men (median age, 67 years), 15 of whom had received previous chemotherapy, were treated. Overall, 46% of patients achieved a positive pain response and 48% achieved a 50%-or-greater reduction in PSA. KPS was high at baseline (80%), and no significant changes in this parameter were observed. Compared with baseline, all scores improved after the first cycle of therapy, particularly emotional (P = 0.015), pain (P = 0.001), constipation (P = 0.001), and global QOL (P = 0.011) scores. After the second cycle, dyspnea scores decreased (P = 0.010). At the last QOL assessment, there also was deterioration in terms of fatigue (P = 0.013), dyspnea (P = 0.010), and physical functioning (P = 0.017). Toxicity was mild and included neutropenia (Grade 3-4, n = 2). CONCLUSIONS: Of these elderly symptomatic patients with HRPC, half had received previous chemotherapy. Weekly docetaxel was found to be associated with improvements in clinical benefit response and in QOL and was well tolerated.

Phase I and pharmacokinetic study of escalating dose of docetaxel administered with granulocyte colony-stimulating factor support in adult advanced solid tumors.

PURPOSE: The purpose of our study was to assess the feasibility, toxicity, and pharmacokinetics of an escalating dose of docetaxel when administered with granulocyte colony-stimulating factor (G-CSF) support every 3 weeks. EXPERIMENTAL DESIGN: Patients with advanced solid malignancies were treated with escalating doses of docetaxel as a 1-h infusion every 3 weeks, supported by s.c. administration of human recombinant glycosilated G-CSF Granocyte (lenograstim), 5 microg/kg/day (from day 4 until neutrophil count >0.5-10(g)/liter for two consecutive days). Plasma sampling was performed to characterize the pharmacokinetics of docetaxel at the new recommended high-dose level. RESULTS: Forty-seven patients were treated with 116 courses of docetaxel at eight dose levels ranging from 100-185 mg/m(2). Dose-limiting toxicities were nonhematologic and included mucositis and dermatitis. Severe skin toxicity observed at 185 mg/m(2) led to discontinuing the study, and 175 mg/m(2) was selected as the recommended dose of docetaxel + G-CSF for future Phase II studies. Analysis of multiple courses revealed dermatitis, mucositis, arthralgia/myalgia, and neuropathy as the main dose-related toxic events. At 175 mg/m(2) mean +/- SD values for docetaxel plasmatic peak, area under the curve, clearance, volume of distribution, and terminal half-life were 6.7 +/- 1.7 microg/ml, 9.7 +/- 4 microg.h/ml, 34.2 +/- 12 liters/h, and 122.7 +/- 124 liters, respectively. Of the 16 patients treated at 175 mg/m(2), 8 patients responded (7 breast cancer and 1 lung cancer patients) including one complete response (1 breast cancer patient). CONCLUSIONS: Using G-CSF support allows substantial dose escalation of docetaxel. Whether such a dose increase improves the response rate warrants further investigation. At the highest dose level studied, pharmacokinetic parameters seem to maintain a linear profile.

Efficacy and tolerance of a scalp-cooling system for prevention of hair loss and the experience of breast cancer patients treated by adjuvant chemotherapy.

The applicability and efficacy of a scalp cooling system were studied in 105 breast cancer patients receiving four cycles of adjuvant chemotherapy with mitoxantrone + cyclophosphamide (NC chemotherapy). Women accepting the scalp-cooling system were compared for alopecia both against those who refused and against a "reference" group of 109 patients similarly treated but without being offered a scalp-cooling system. Hair loss in the 105 study patients was evaluated by nurses using World Health Organization (WHO) criteria at each cycle of chemotherapy. Concomitantly, tolerance and side-effects of the helmet were also recorded in 48 accepting patients. Similarly to reference group patients, a subsample of 27 accepting patients self-assessed hair loss using a specific questionnaire measuring its frequency and severity and the distress associated with this symptom. Nurses' ratings ( n = 105) indicated that hair loss frequency was constantly lower, at each cycle of chemotherapy, in study patients with scalp-cooling system ( n = 77) than in those without ( n = 28). Differences between the two groups were statistically significant at cycles 1 and 3 ( P < 0.05). When compared with those reported by reference group patients ( n = 109), study patients' self-measures of alopecia frequency ( n = 27) provided even more marked results than those achieved by nurses (cycles 1-3: P < 0.01; cycle 4: P < 0.05). Tolerance was generally good and no scalp metastasis was observed among the 77 accepting patients followed up. This study demonstrates that scalp cooling was an effective method of protection against hair loss caused by NC chemotherapy. Its routine use as part of adjuvant chemotherapy, especially in cancers with low prevalences of scalp metastasis, should be seriously considered.

Retinoids, cisplatin and interferon-alpha in recurrent or metastatic cervical squamous cell carcinoma: clinical results of 2 phase II trials.

BACKGROUND: There is no standard treatment for inoperable recurrent or metastatic cancer of the uterine cervix. Retinoids and interferon, in combination with cytotoxic compounds, have been shown to be active in squamous cell carcinoma (SCC). This phase II trial sought to estimate the response rate and the tolerance to a 3-month treatment combining cisplatin, interferon-alpha (IFN-alpha) and all-trans-retinoic (tRA) or 13 cis retinoic acid (13Cis), in women with recurrent or metastatic cervical SCC. PATIENTS AND METHODS: Between November 1994 and October 1996, 33 patients, who had previously received aggressive treatment, and with metastatic and/or bulky disease were enrolled: 22 received tRA(40 mg/m(2)/day), 11 received 13Cis (1 mg/kg/day) in combination with IFN-alpha (6.106 UI/day SC) for 84 days plus cisplatin (40 mg/m(2)IV, days 1, 28 and 56). RESULTS: All patients were evaluable for response and/or toxicity. Toxicities were easily manageable and were never life-threatening, with major grade 3/4 vomiting (54%) and asthenia (54%). Seventeen patients (52%) stopped or reduced treatment because of toxicity or progression. Six objective responses (18%) were observed. No complete response was recorded. Median response duration was 4 months. Time to progression was 9 months [range 3.3 to 20.9] for responders and 7 months [range 1.7 to 32] for all patients. CONCLUSIONS: Regarding toxicity, this regimen should no longer be recommended in previously treated, advanced uterine SCC. However, the consistent response rate reported here may warrant further investigations in an early setting. Retinoid-based treatment with cytokines remains a promising field of research.
