A pharmacist-led interprofessional medication adherence program improved adherence to oral anticancer therapies: The OpTAT randomized controlled trial.

BACKGROUND: Oral anticancer therapies such as protein kinase inhibitors (PKIs) are increasingly prescribed in cancer care. We aimed to evaluate the impact of a pharmacist-led interprofessional medication adherence program (IMAP) on patient implementation (dosing history), persistence (time until premature cessation of the treatment) and adherence to 27 PKIs prescribed for various solid cancers, as well as the impact on patients' beliefs about medicines (BAM) and quality of life (QoL). METHODS: Patients (n = 118) were randomized 1:1 into two arms. In the intervention arm, pharmacists supported patient adherence through monthly electronic and motivational feedback, including educational, behavioral and affective components, for 12 months. The control arm received standard care plus EM without intervention. All PKIs were delivered in electronic monitors (EMs). Medication implementation and adherence were compared between groups using generalized estimating equation models, in which relevant covariables were included; persistence was compared with Kaplan‒Meier curves. Information on all treatment interruptions was compiled for the analysis. Questionnaires to evaluate BAM and QoL were completed among patients who refused and those who accepted to participate at inclusion, 6 and 12 months post-inclusion or at study exit. RESULTS: Day-by-day PKI implementation was consistently higher and statistically significant in the intervention arm (n = 58) than in the control arm (n = 60), with 98.1% and 95.0% (Δ3.1%, 95% confidence interval (CI) of the difference 2.5%; 3.7%) implementation at 6 months, respectively. The probabilities of persistence and adherence were not different between groups, and no difference was found between groups for BAM and QoL scores. No difference in BAM or QoL was found among patients who refused versus those who participated. The intervention benefited mostly men (at 6 months, Δ4.7%, 95% CI 3.4%; 6.0%), those younger than 60 years (Δ4.0%, 95% CI 3.1%; 4.9%), those who had initiated PKI more than 60 days ago before inclusion (Δ4.5%, 95% CI 3.6%; 5.4%), patients without metastasis (Δ4.5%, 95% CI 3.4%; 5.7%), those who were diagnosed with metastasis more than 2 years ago (Δ5.3%, 95% CI 4.3%; 6.4%) and those who had never used any adherence tool before inclusion (Δ3.8%, 95% CI 3.1%; 4.5%). CONCLUSIONS: The IMAP, led by pharmacists in the context of an interprofessional collaborative practice, supported adherence, specifically implementation, to PKIs among patients with solid cancers. To manage adverse drug events, PKI transient interruptions are often mandated as part of a strategy for treatment and adherence optimization according to guidelines. Implementation of longer-term medication adherence interventions in the daily clinic may contribute to the improvement of progression-free survival.

[Salivary gland cancer: new therapeutic approaches]. / Cancers des glandes salivaires : nouvelles approches thérapeutiques.

Salivary gland carcinomas are rare, characterized by a diversity of histological subtypes associated with variable clinical behavior and prognosis with usually a poor response to chemotherapy. In this context, molecular alterations have been identified and represent potential therapeutic targets: overexpression of human epidermal growth factor receptor 2 (HER2) and androgen receptors in salivary duct cancer, NOTCH mutations in adenoid cystic carcinoma, NTRK gene fusion in secretory carcinoma. Screening for these molecular alterations is mandatory in all patients with recurrent or metastatic salivary gland cancer as it may allow an individualized treatment.

Les carcinomes des glandes salivaires sont rares et se caractérisent par une grande diversité de sous-types histologiques associés à des comportements cliniques différents, à un pronostic variable et à une réponse habituellement médiocre à la chimiothérapie. Dans ce contexte, des altérations moléculaires ont été identifiées et représentent de nouvelles cibles thérapeutiques : surexpression du récepteur 2 du facteur de croissance épidermique humain (HER2) et des récepteurs aux androgènes dans le cancer des canaux salivaires, mutations activatrices de NOTCH dans le carcinome adénoïde kystique, fusion de gène NTRK dans le carcinome sécrétoire notamment. Ces altérations moléculaires doivent être recherchées chez tous les patients présentant un cancer des glandes salivaires récidivant ou métastatique et permettent d'individualiser sa prise en charge.

[Oncology: what's new in 2022]. / Oncologie : ce qui a changé en 2022.

The past year has brought several innovations in medical oncology, opening up promising new options for many solid tumors, both localized and metastatic. Immunotherapy, a real spearhead of emerging therapies in metastatic diseases, is seeing its use extend to adjuvant and neoadjuvant modalities, particularly in colon and lung cancers. 2022 also sees a great deal of focus on targeted therapies, as well as on antibody-drug conjugates, which creates new standards in both breast and lung cancers. Here we present the major advances in solid tumors.

Papillary Thyroid Carcinoma with Desmoid-Type Fibromatosis: Review of Published Cases.

Desmoid-type fibromatosis (DTF) is a very rare variant of papillary thyroid carcinoma (PTC). It is essentially a dual tumor with a component of classical PTC with malignant epithelial proliferation (BRAF-mutated) and another component of mesenchymal proliferation (CTNNB1-mutated). We conducted a literature review on PTC-DTF. In total, 31 articles were identified, that together reported on 54 patients. The mean age was 47 years, with a 2.2:1 female predominance. No ultrasound features were found to be helpful in differentiating PTC-DTF from other PTC variants. Of the 43 cases that reported histological details, 60% had locally infiltrative disease (T3b or T4). Around 48% had cervical lymph node metastases, but none had distant metastases. While PTC-DTF may be locally more aggressive than classic PTC, its overall behavior is similar and can include extrathyroidal extension and lymph node metastases, which may contain a stromal component and show extranodal invasion. The mainstay of treatment for PTC-DTF is surgery, and the DTF component is not expected to be sensitive to radioactive iodine. External radiotherapy, non-steroidal anti-inflammatory drugs, tyrosine kinase inhibitors and chemotherapy have also been used in selected cases. Due to the rarity of these tumors and the lack of specific treatment guidelines, management should be discussed in a multidisciplinary team.

Optimizing Oral Targeted Anticancer Therapies Study for Patients With Solid Cancer: Protocol for a Randomized Controlled Medication Adherence Program Along With Systematic Collection and Modeling of Pharmacokinetic and Pharmacodynamic Data.

BACKGROUND: The strengthening or substitution of intravenous cytotoxic chemotherapy cycles by oral targeted anticancer therapies, such as protein kinase inhibitors (PKIs), has provided impressive clinical benefits and autonomy as well as a better quality of life for patients with cancer. Despite these advances, adverse event management at home and medication adherence remain challenging. In addition, PKI plasma concentrations vary significantly among patients with cancer receiving the same dosage, which could explain part of the observed variability in the therapeutic response. OBJECTIVE: The aim of this optimizing oral targeted anticancer therapies (OpTAT) study is to optimize and individualize targeted anticancer treatments to improve patient care and self-monitoring through an interprofessional medication adherence program (IMAP) combined with measurement PKI plasma concentrations. METHODS: The OpTAT study has two parts: (1) a 1:1 randomized medication adherence program, in which the intervention consists of regular motivational interviewing sessions between the patient and the pharmacist, along with the delivery of PKIs in electronic monitors, and (2) a systematic collection of blood samples and clinical and biological data for combined pharmacokinetic and pharmacodynamic analysis. On the basis of the electronic monitor data, medication adherence will be compared between groups following the three operational definitions: implementation of treatment during the persistent period, persistence with treatment and longitudinal adherence. The implementation will be described using generalized estimating equation models. The persistence of PKI use will be represented using a Kaplan-Meier survival curve. Longitudinal adherence is defined as the product of persistence and implementation. PKI pharmacokinetics will be studied using a population approach. The relationship between drug exposure and efficacy outcomes will be explored using Cox regression analysis of progression-free survival. The relationship between drug exposure and toxicity will be analyzed using a pharmacokinetic-pharmacodynamic model and by logistic regression analysis. Receiver operating characteristic analyses will be applied to evaluate the best exposure threshold associated with clinical benefits. RESULTS: The first patient was included in May 2015. As of June 2021, 262 patients had participated in at least one part of the study: 250 patients gave at least one blood sample, and 130 participated in the adherence study. Data collection is in process, and the final data analysis is planned to be performed in 2022. CONCLUSIONS: The OpTAT study will inform us about the effectiveness of the IMAP program in patients with solid cancers treated with PKIs. It will also shed light on PKI pharmacokinetic and pharmacodynamic properties, with the aim of learning how to adapt the PKI dosage at the individual patient level to increase PKI clinical suitability. The IMAP program will enable interprofessional teams to learn about patients' needs and to consider their concerns about their PKI self-management, considering the patient as an active partner.

[Anaplastic thyroid carcinoma : new therapeutic approaches]. / Carcinome anaplasique de la thyroïde : nouvelles approches thérapeutiques.

Anaplastic thyroid cancer (ATC) is among the most aggressive cancers with a median overall survival of 4 months and a disease-specific mortality of close to 100%. As soon as the diagnosis is suspected or established, urgent referral to an experienced multidisciplinary center is imperative. Chemotherapy has limited efficacy. Molecular analyses, together with the availability of novel targeted therapies and immunotherapies, now permit to improve outcomes. In particular, targeted therapy with dabrafenib and trametinib is indicated as first-line therapy for BRAF V600E-mutated ATC.

Le cancer anaplasique de la thyroïde (CAT) compte parmi les cancers les plus agressifs avec une survie médiane de 4 mois et une mortalité spécifique à la maladie proche de 100 %. Dès que le diagnostic est suspecté ou établi, une orientation urgente vers un centre multidisciplinaire expérimenté est essentielle. La chimiothérapie a une efficacité limitée. Les analyses moléculaires, ainsi que la disponibilité de nouvelles thérapies ciblées et d'immunothérapies, permettent désormais d'améliorer les résultats. En particulier, le CAT avec mutation BRAF V600E bénéficie d'une combinaison de thérapies ciblées par dabrafénib et tramétinib en traitement de première ligne.

Phase I Trial of Debio 1143, an Antagonist of Inhibitor of Apoptosis Proteins, Combined with Cisplatin Chemoradiotherapy in Patients with Locally Advanced Squamous Cell Carcinoma of the Head and Neck.

PURPOSE: Debio 1143 is an oral antagonist of inhibitor of apoptosis proteins, which enhances tumor response with concomitant chemoradiotherapy. Addition of Debio 1143 to cisplatin-based chemoradiotherapy in locally advanced squamous cell carcinomas of the head and neck (LA-SCCHN) was evaluated in a phase I/II study to determine the MTD and recommended phase II dose (RP2D). Here, phase I results are reported. PATIENTS AND METHODS: Treatment-naïve patients with LA-SCCHN (stages III/IVA/IVB) received Debio 1143 (100, 200, 300 mg/day), for 14 days every 3 weeks, with cisplatin (100 mg/m², every 3 weeks), for three cycles, and concomitant conventional fractionation radiotherapy (70 Gy/7 weeks). Dose-limiting toxicity (DLT) was evaluated over 9 weeks using continual reassessment. RESULTS: Fourteen patients were treated/evaluable for DLT. Median age was 64.5 years, and all patients were current/former smokers. Primary tumors were hypopharynx, oropharynx (all human papillomavirus/p16 negative), larynx, and oral cavity. Two of six patients at 200 mg/day had DLT (grade 3 tubular necrosis, grade 3 aspartate aminotransferase/alanine aminotransferase increase, grade 4 febrile neutropenia, and grade 3 lipase increase), which was considered the MTD and RP2D. Common grade 3-4 adverse events were dysphagia (36%) and mucositis (29%). Laboratory abnormalities were frequent and generally mild, including anemia, white blood cell decrease, and increased creatinine. Addition of Debio 1143 did not compromise chemotherapy administration. Overall locoregional control rate at 18 months was 85%. Overall response rate was 85%, including 69% complete responses. Progression-free survival rate at 24 months was 74%. CONCLUSIONS: The RP2D of Debio 1143 is 200 mg/day for 14 days, every 3 weeks, when combined with concomitant high-dose cisplatin chemoradiotherapy in LA-SCCHN. Debio 1143 addition to chemoradiotherapy was safe and manageable. Preliminary efficacy is encouraging and supports further development.

Immunotherapies and Future Combination Strategies for Head and Neck Squamous Cell Carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is often diagnosed at an advanced stage and has a dismal prognosis. Nearly 10 years after the approval of cetuximab, anti-PD1/PD-L1 checkpoint inhibitors are the first drugs that have shown any survival benefit for the treatment on platinum-refractory recurrent/metastatic (R/M) HNSCC. Furthermore, checkpoint inhibitors are better tolerated than chemotherapy. The state of the art in the treatment of R/M HNSCC is changing, thanks to improved results for checkpoint inhibitors. Results for these treatments are also awaited in curative settings and for locally advanced HNSCC. Unfortunately, the response rate of immunotherapy is low. Therefore, the identification of predictive biomarkers of response and resistance to anti-PD1/PD-L1 is a key point for better selecting patients that would benefit the most from immunotherapy. Furthermore, the combination of checkpoint inhibitors with various agents is being currently evaluated to improve the response rate, prolong response duration, and even increase the chances for a cure. In this review, we summarize the most important results regarding immune targeting agents for HNSCC, predictive biomarkers for resistance to immune therapies, and future perspectives.

Cisplatin Eligibility Issues and Alternative Regimens in Locoregionally Advanced Head and Neck Cancer: Recommendations for Clinical Practice.

Well-designed randomized trials provide the highest level of scientific evidence to guide clinical decision making. In chemoradiotherapy of locally advanced squamous cell carcinoma of the head and neck (SCCHN), data support the use of three cycles of 100 mg/m2 cisplatin given every 3 weeks concurrently with conventionally fractionated external beam radiotherapy, although a full compliance with all three cycles is reserved to only about two thirds of initially eligible cases. On an individual patient level, practicing oncologists have to determine whether the patient is a suitable candidate for this treatment or whether contraindications exist. In the latter case, an adequate alternative has to be offered. In this regard, to facilitate triaging of medical information, we reviewed available publications on this topic and prepared practice-oriented recommendations for systemic treatment concurrent to definitive and post-operative radiotherapy. Even if no contraindications for the standard-of-care cisplatin apply, clinicians may opt for alternative regimens by adjusting the peak dose, cumulative dose, or timing of cisplatin. Relative contraindications pose the major issue in clinical practice, as very limited data is available in the literature and final decisions are usually based on an expert opinion or retrospective cohort studies. In the case of absolute interdiction of cisplatin, several alternative regimens incorporating carboplatin, 5-fluorouracil, cetuximab, and docetaxel are available. At the same time, it should be kept in mind that radiotherapy alone represents a viable option with hyperfractionation being particularly beneficial in the definitive management of limited nodal disease. Ideally, all treatment propositions should be discussed within multidisciplinary tumor boards taking into account the patient- and disease-related characteristics as well as local logistics and reimbursement policies.

18F-FDG PET metabolic-to-morphological volume ratio predicts PD-L1 tumour expression and response to PD-1 blockade in non-small-cell lung cancer.

PURPOSE: Anti-PD-1/PD-L1 blockade can restore tumour-specific T-cell immunity and is an emerging therapy in non-small-cell lung cancer (NSCLC). We investigated the correlation between 18F-FDG PET/CT-based markers and tumour tissue expression of PD-L1, necrosis and clinical outcome in patients receiving checkpoint inhibitor treatment. METHODS: PD-Li expression in biopsy or resection specimens from 49 patients with confirmed NSCLC was investigated by immunohistochemistry. Maximum standardized uptake value (SUVmax), mean SUV (SUVmean), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) were obtained from 18F-FDG PET/CT images. The ratio of metabolic to morphological lesion volumes (MMVR) and its association with PD-L1 expression in each lesion were calculated. The associations between histologically reported necrosis and 18F-FDG PET imaging patterns and radiological outcome (evaluated by iRECIST) following anti-PD-1/PD-L1 therapy were also analysed. In 14 patients, the association between necrosis and MMVR and tumour immune contexture were analysed by multiple immunofluorescent (IF) staining for CD8, PD-1, granzyme B (GrzB) and NFATC2. RESULTS: In total, 25 adenocarcinomas and 24 squamous cell carcinomas were analysed. All tumours showed metabolic 18F-FDG PET uptake. MMVR was correlated inversely with PD-L1 expression in tumour cells. Furthermore, PD-L1 expression and low MMVR were significantly correlated with clinical benefit. Necrosis was correlated negatively with MMVR. Multiplex IF staining showed a greater frequency of activated CD8+ cells in necrotic tumours than in nonnecrotic tumours in both stromal and epithelial tumour compartments. CONCLUSION: This study introduces MMVR as a new imaging biomarker and its ability to noninvasively capture increased PD-L1 tumour expression and predict clinical benefit from checkpoint blockade in NSCLC should be further evaluated.

Lenvatinib in Advanced Radioiodine-Refractory Thyroid Cancer - A Retrospective Analysis of the Swiss Lenvatinib Named Patient Program.

Purpose: Differentiated thyroid cancer (DTC) accounts for approximately 95% of thyroid carcinomas. In the metastatic RAI-refractory disease, chemotherapy has very limited efficacy and is associated with substantial toxicity. With increasing knowledge of the molecular pathogenesis of DTC, novel targeted therapies have been developed. Lenvatinib is a tyrosine kinase inhibitor (TKI) with promising clinical activity based on the randomized phase III SELECT trial. In Switzerland, a Named Patient Program (NPP) was installed to bridge the time gap to Swissmedic approval. Here, we report the results from the Swiss Lenvatinib NPP including patients with metastatic RAI-refractory DTC. Methods: Main inclusion criteria for the Swiss NPP were RAI-refractory DTC, documented disease progression, Eastern Cooperative Oncology Group (ECOG) performance status 0-3. The number of previous therapies was not limited. The Swiss Lenvatinib NPP was initiated in June 2014 and was closed in October 2015 with the approval of the drug. Results: Between June 2014 and October 2015, 13 patients with a median age of 72 years have been enrolled. Most patients (69%) had at least one prior systemic therapy, mainly sorafenib. 31% of patients showed a PR and 31% SD. Median progression free survival was 7.2 months and the median overall survival was 22.7 months. Dose reduction due to adverse events was necessary in 7 patients (53%). At the time of analysis 6 patients (47%) were still on treatment with a median time on treatment of 9.98 months. Conclusions: Our results show that lenvatinib has reasonable clinical activity in unselected patients with RAI-refractory thyroid cancer with nearly two-third of patients showing clinical benefit. The toxicity profile of lenvatinib is manageable.

[Head and neck cancer : promising results of immunotherapy]. / Cancers de la sphère ORL : l'immunothérapie donne de la voix !

Immunotherapy, especially checkpoint inhibitors such as anti-PD1 and anti-PDL1 antibodies, has changed the standard of care and the prognosis of melanoma, but also more recently of lung cancer, renal cancer and Hodgkin lymphoma. Results of preliminary studies in head and neck squamous cell carcinoma (HNSCC) as well as in less frequent tumors of the region, such as nasopharyngeal carcinoma and high grade salivary gland carcinoma, are also promising. Indeed, in a recent phase 3 study, the PD1 inhibitor nivolumab has recently demonstrated a significant improvement in overall survival for platin-resistant recurrent and/or metastatic HNSCC.

L'immunothérapie, en particulier les inhibiteurs de points de contrôles immunitaires (checkpoints) tels que les anticorps anti-PD1 et anti-PDL1, a déjà modifié la prise en charge standard et le pronostic du mélanome, mais également du cancer pulmonaire, rénal et du lymphome de Hodgkin. Les résultats des études préliminaires sont aussi prometteurs dans le traitement des carcinomes épidermoïdes ORL, ainsi que pour des cancers plus rares de la sphère tête et cou, comme les carcinomes nasopharyngés et les carcinomes de haut grade des glandes salivaires. Le traitement anti-PD1 par nivolumab a récemment démontré un bénéfice de survie globale chez les patients présentant un carcinome épidermoïde ORL récidivant et/ou métastatique résistant aux platines dans une étude de phase 3.
