Safety and quality of cystectomy and pelvic lymph node dissection after neoadjuvant durvalumab and cisplatin/gemcitabine.

OBJECTIVE: To report on the surgical safety and quality of pelvic lymph node dissection (PLND) in patients treated with radical cystectomy (RC) and PLND for muscle-invasive bladder cancer (MIBC) after neoadjuvant chemo-immunotherapy. PATIENTS AND METHODS: The Swiss Group for Clinical Cancer Research (SAKK) 06/17 was an open-label single-arm phase II trial including 61 cisplatin-fit patients with clinical stage (c)T2-T4a cN0-1 operable urothelial MIBC or upper urinary tract cancer. Patients received neoadjuvant cisplatin/gemcitabine and durvalumab followed by surgery. Prospective quality assessment of surgeries was performed via central review of intraoperative photographs. Postoperative complications were assessed using the Clavien-Dindo Classification. Data were analysed descriptively. RESULTS: A total of 50 patients received RC and PLND. All patients received neoadjuvant chemo-immunotherapy. The median (interquartile range) number of lymph nodes removed was 29 (23-38). No intraoperative complications were registered. Grade ≥III postoperative complications were reported in 12 patients (24%). Complete nodal dissection (100%) was performed at the level of the obturator fossa (bilaterally) and of the left external iliac region; in 49 patients (98%) at the internal iliac region and at the right external iliac region; in 39 (78%) and 38 (76%) patients at the right and left presacral level, respectively. CONCLUSION: This study supports the surgical safety of RC and PLND following neoadjuvant chemo-immunotherapy in patients with MIBC. The extent and completeness of protocol-defined PLND varies between patients, highlighting the need to communicate and monitor the surgical template.

Multidisciplinary recommendations for essential baseline functional and laboratory tests to facilitate early diagnosis and management of immune-related adverse events among cancer patients.

Immune checkpoint inhibitors (ICIs) have fundamentally changed the treatment landscape of various cancers. While ICI treatments result in improved survival, quality of life and are cost-effective, the majority of patients experience at least one immune-related adverse event (irAE). Many of these side effects cause little discomfort or are asymptomatic; however, irAEs can affect any organ and are potentially life-threatening. Consequently, early diagnosis and appropriate treatment of irAEs are critical for optimizing long-term outcomes and quality of life in affected patients. Some irAEs are diagnosed according to typical symptoms, others by abnormal findings from diagnostic tests. While there are various guidelines addressing the management of irAEs, recommendations for the early recognition of irAEs as well as the optimal extent and frequency of laboratory tests are mostly lacking. In clinical practice, blood sampling is usually performed before each ICI administration (i.e., every 2-3 weeks), often for several months, representing a burden for patients as well as health care systems. In this report, we propose essential laboratory and functional tests to improve the early detection and management of irAEs and in cancer patients treated with ICIs. These multidisciplinary expert recommendations regarding essential laboratory and functional tests can be used to identify possible irAEs at an early time point, initiate appropriate interventions to improve patient outcomes, and reduce the burden of blood sampling during ICI treatment.

Sex differences in treatment patterns for non-advanced muscle-invasive bladder cancer: a descriptive analysis of 3484 patients of the Netherlands Cancer Registry.

PURPOSE: Bladder cancer (BC) is a common malignancy with well-established differences in incidence, clinical manifestation and outcomes between men and women. It is unknown to what extent disparities in outcomes are influenced by differences in treatment approaches. This paper describes treatment patterns among men and women with muscle-invasive BC focusing on curative treatment (radical cystectomy or trimodal therapy). METHODS: A retrospective population-based cohort study was performed with data from the Netherlands Cancer Registry. All patients newly diagnosed with muscle-invasive, non-advanced BC (MIBC, cT2-4a, N0/X, M0/X) in the years 2018, 2019 and 2020 were identified. Patient and tumor characteristics and initial treatment were compared between men and women with descriptive statistics and multivariable logistic regression analyses. RESULTS: A total of 3484 patients were diagnosed with non-advanced MIBC in 2018-2020 in the Netherlands, of whom 28% were women. Women had higher T-stage and more often non-urothelial histology. Among all strata of clinical T-stage, women less often received treatment with curative intent (radical cystectomy [RC] or trimodality treatment). Among RC-treated patients, women more often received neoadjuvant treatment (except for cT4a disease). After adjustment for pre-treatment factors, odds ratios were indicative of women having lower probability of receiving curative treatment and RC specifically, and higher probability to receive NAC when treated with RC then men, although not statistically significant. CONCLUSIONS: Considerable differences in treatment patterns between men and women with MIBC exist. A more considerate role of the patient's sex in treatment decisions could help decrease these differences and might mitigate disparities in outcomes.

Androgen Signaling in the Tumor Microenvironment.

The key function of mesenchymal/stromal androgen receptor (AR) signaling for prostate development has been well documented by tissue recombination experiments. Some studies have addressed the expression and function of AR in stromal cells in prostate cancer, yet our understanding of the role of stromal AR in other tissues beyond prostate is still insufficient.Genomic analysis has revealed that cellular responses to androgens differ between epithelial and stromal cells. AR in stromal cells seems not to act via classical AR transcription factors such as FOXA1 but rather depends on the JUN/AP1 complex. Stromal AR appears to have tumor-promoting and tumor-protective functions depending on tumor stage. Loss of AR signaling in fibroblasts has been detected already in premalignant lesions in the skin and prostate and has been associated with tumor induction in xenografts of skin cancer and aggressive disease features and poor patient prognosis in prostate cancer. Moreover, AR expression is found on virtually all tissue-infiltrating immune cells and plays critical roles in immune cell function. These findings suggest a potential deleterious impact of current androgen deprivation therapies which inhibit both epithelial and stromal AR, highlighting the need to develop tissue-specific AR inhibitors.

[ENT management of head and neck cutaneous melanoma]. / Prise en charge par l'ORL des mélanomes cutanés cervico-faciaux.

A quarter of cutaneous melanomas occur on the head and neck. Despite close collaboration between the dermatology, oncology, pathology, nuclear medicine and otorhinolaryngology departments, the survival of patients presenting with this type of melanomas remains inferior to that of other parts of the body. The morbidity of head and neck surgery significantly alters the quality of life. Therefore, specific multidisciplinary expertise is required. We present here the specificities of ENT management.

Un quart des mélanomes cutanés se présentent au niveau de la tête et du cou. Malgré une étroite collaboration entre les services de dermatologie, oncologie, pathologie, médecine nucléaire et oto-rhino-laryngologie (ORL), la survie des patients qui présentent ce type de mélanomes reste inférieure à celle des patients ayant un mélanome d'une autre partie du corps. La morbidité d'une chirurgie cervico-faciale modifie significativement la qualité de vie. Ainsi, une expertise spécifique multidisciplinaire est nécessaire. Nous présentons ici les spécificités de la prise en charge ORL des mélanomes cervico-faciaux.

[Locally advanced and metastatic melanoma : novelties]. / Mélanome localement avancé et métastatique : nouveautés.

The standard of care of melanoma patients has evolved at a rapid pace with the advent of immune checkpoint inhibitors and BRAF and MEK inhibitors. ESMO guidelines were revised in September 2019 to integrate the results of recent studies that broaden the indication of these treatments to the adjuvant setting and validated new limitations to completion lymph node dissection in the case of a positive sentinel lymph node biopsy in locally advanced melanoma. We hereby detail the main novelties of the revised ESMO 2019 guidelines.

L'évolution de la prise en charge des patients atteints d'un mélanome a été accélérée avec l'avènement des inhibiteurs de points de contrôle immunitaire et des inhibiteurs BRAF et MEK. Les guidelines de la Société européenne d'oncologie médicale (ESMO) ont été révisées en septembre 2019 pour intégrer les résultats des récentes études, élargissant les indications de ces traitements en situation adjuvante. La place du curage ganglionnaire en cas d'atteinte du ganglion sentinelle dans les mélanomes localement avancés est aussi rediscutée. Nous détaillons ici les principales nouveautés des guidelines de l'ESMO 2019.

[Cardiotoxicity of immune checkpoint inhibitors used in cancer treatment]. / Cardiotoxicité des inhibiteurs de points de contrôle immunitaire utilisés dans le traitement des cancers.

Immune checkpoint inhibitors (ICI) have revolutionized the field of oncology, by reshaping the prognosis of many cancers and are progressively becoming the standard of care. One of the costs of these advances is the emergence of a new spectrum of immune-related adverse events (irAEs), of which cardiovascular irAEs are particularly feared. ICI-induced myocarditis is often a diagnostic challenge because of the vast heterogeneity of clinical presentations, and it is associated with a high mortality rate of around 50%. The present article summarizes the cardiac manifestations, the diagnostic strategy and the therapeutic management of patients with ICI-induced myocarditis used in the treatment of cancer.

Les inhibiteurs de points de contrôle immunitaire (ICI), ou immune checkpoint inhibitors (ICI), ont révolutionné la prise en charge de nombreux cancers en améliorant significativement la survie des patients et en devenant progressivement la norme de soins. Cette efficacité a néanmoins pour prix un taux élevé d'effets indésirables immunomédiés avec un large spectre d'organes touchés. Les toxicités cardiaques, dominées par la myocardite induite par les ICI, sont particulièrement redoutées du fait des difficultés diagnostiques et du risque d'évolution rapidement défavorable associée à une mortalité élevée, de l'ordre de 50 %. Le présent article s'intéresse aux manifestations cardiaques, à la stratégie diagnostique ainsi qu'à la prise en charge des patients présentant une myocardite induite par les ICI utilisés dans le traitement du cancer.

Human epidermal growth factor receptor 2-positive digestive tumors.

PURPOSE OF REVIEW: This manuscript aims at providing an update and overview on the role of Human epidermal growth factor receptor 2 (HER2) testing and HER2-directed therapies in digestive tumors. RECENT FINDINGS: Phase 3 trial data demonstrating a survival benefit of HER2-targeting treatments are limited to gastric cancer. However, HER2 positivity is also found in 5-6% of colorectal, 7% of pancreatic, and 16% of extrahepatic biliary cancers. Although phase 2 trial data support the use of the combination of trastuzumab and lapatinib with chemotherapy in HER2-positive colorectal cancer, the patient's benefit from targeted treatment of HER2-positive biliary or pancreatic neoplasms is currently unclear, and further clinical trials are necessary. SUMMARY: With the exception of gastric cancer, there are currently no defined guidelines for HER2 testing in other digestive tumors. Various HER2-targeting therapies, which are standard of care in HER2-positive breast cancer, failed in HER2-positive gastric cancers. Thus, the predictive value of HER2 overexpression depends on the tumor type, and results of breast cancer trials cannot a priori be extrapolated to digestive cancers. Next-generation sequencing panel diagnostics may furthermore identify targetable activating mutations in gastric, extrahepatic biliary, and colorectal cancer, particularly if traditional testing (immunohistochemistry/in-situ hybridization) is negative. However, their clinical relevance needs to be determined.

TGF-ß1-containing exosomes from injured epithelial cells activate fibroblasts to initiate tissue regenerative responses and fibrosis.

Hypoxia is associated with tissue injury and fibrosis but its functional role in fibroblast activation and tissue repair/regeneration is unknown. Using kidney injury as a model system, we demonstrate that injured epithelial cells produce an increased number of exosomes with defined genetic information to activate fibroblasts. Exosomes released by injured epithelial cells promote proliferation, α-smooth muscle actin expression, F-actin expression, and type I collagen production in fibroblasts. Fibroblast activation is dependent on exosomes delivering TGF-ß1 mRNA among other yet to be identified moieties. This study suggests that TGF-ß1 mRNA transported by exosomes constitutes a rapid response to initiate tissue repair/regenerative responses and activation of fibroblasts when resident parenchyma is injured. The results also inform potential utility of exosome-targeted therapies to control tissue fibrosis.

Successful treatment of immune checkpoint inhibitor-related periaortitis.

We report a 64-year-old patient with melanoma receiving ipilimumab and nivolumab therapy who presented with a periaortic soft tissue mass around the abdominal aorta on restaging fluorodeoxyglucose positron emission tomography/computed tomography imaging. Clinical, laboratory, and radiologic findings resulted in a diagnosis of immune checkpoint inhibitor-related periaortitis. Periaortitis is a rare disease presenting with fibro-inflammatory tissue around the aorta and may lead to serious complications. Immune checkpoint inhibitors were discontinued, and the patient was treated with glucocorticoids, leading to a complete resolution of the periaortitis. To our knowledge, this is only the third reported case of immune checkpoint inhibitor-related periaortitis.

Awareness of the impact of sex and gender in the disease risk and outcomes in hematology and medical oncology-a survey of Swiss clinicians.

BACKGROUND: Although male and female cancer patients are distinct in many ways, there is a limited understanding in the differences between male and female biology and differing pharmacokinetic responses to cancer drugs. In fact, sex and gender are currently not considered in most treatment decisions in the fields of oncology and hematology. The lack of knowledge about potential sex differences in both disciplines may lead to differences in treatment efficacy, toxicity, and the overall survival (OS) of patients. AIM: To evaluate their awareness about sex and gender in clinical practice we surveyed Swiss hematologists and oncologists from September to November 2022. METHODS: We collected data about the clinical knowledge, experimental research, palliative care, quality of life, as well as the participant perception of the importance of sex and gender. We identified 767 eligible clinicians, of whom 150 completed the survey (20% response rate). RESULTS: While most participants agreed that sex and gender were relevant when treating patients, it became clear that fewer participants knew about sex and gender differences in treatment toxicity and survival, which in turn would affect the treatment of their patients. Most participants agreed that this topic should be integrated into continuing education and research. CONCLUSION: Our findings indicate the need for more awareness and training on sex and gender in cancer research and clinical care among oncologists and hematologists. Ideally, by better educating medical students and health professionals, a demand is created for improving research policies, publications and therefore patient care.

Intersectionality Between Country, Gender and Funding in Authorship for Phase III Trials Presented at the ASCO Annual Meeting 2022.

PURPOSE: Multiple disparities have been recognized in the area of location, gender, and funding for leadership in oncology clinical trials. Understanding their intersectionality is crucial to be able to formulate policies and actions, to ensure research is representative of the global oncology community. Here, data from phase III trials presented at the ASCO Annual Meeting of 2022 (ASCO22) were analyzed. METHODS: The location of institution, gender of lead and senior authors, and funding source for solid tumor phase III trial abstracts presented at the ASCO22 were analyzed. World Bank analytical grouping version 2021-2022 was used to describe regions and countries as high (HIC), upper-middle (UMIC), lower-middle (LoMIC), and low-income (LIC). RESULTS: Across 239 phase III abstracts, lead and senior authors respectively represented HIC institutions in 83% and 85%, UMIC in 13% and 12%, and LoMIC in 4% and 3%. No authors worked in LICs or sub-Saharan Africa. Women accounted for 29% of lead and 23% of senior authors. This distribution persisted across regions, with women as lead authors ranging from 19% (UMIC) to 31% (HIC), and as senior authors from 7% (UMIC) to 25% (HIC). Industry funded 62% of trials, academia 17%, and others 15%; 6% lacked funding. Industry funding was highest in HIC trials (66% for lead and senior authors), followed by UMICs (55% lead, 53% senior) and LoMICs (11% lead, 0% senior). Industry-sponsored trials were proportionally equally represented among female and male senior authors (63% each). CONCLUSION: There is marked intersectionality in leadership of oncology clinical trials presented at the world's largest oncology conference.

Treatment Patterns and Use of Immune Checkpoint Inhibitors Among Patients with Metastatic Bladder Cancer in a Dutch Nationwide Cohort.

Since 2017, two immune checkpoint inhibitors (ICIs) have become the standard of care for the treatment of metastatic urothelial carcinoma in Europe: pembrolizumab as second-line therapy and avelumab as maintenance therapy. Our aim was to describe the use of ICIs as first and later lines of treatment in patients with metastatic bladder cancer (mBC) in the Netherlands. We identified all patients diagnosed with primary mBC between 2018 and 2021 in the Netherlands from the Netherlands Cancer Registry (NCR). NCR data were supplemented with data from the Dutch nationwide Prospective Bladder Cancer Infrastructure (ProBCI) collected from medical files, with follow-up until death or end of data collection on January 1, 2023. A total of 1525 patients were diagnosed with primary mBC between 2018 and 2021 in the Netherlands. Of these, 34.7% received at least one line of systemic treatment with chemotherapy or ICI. After first-line platinum-based chemotherapy, 34.1% received second-line ICI and 3.9% received maintenance ICI. Among patients who completed or discontinued first-line cisplatin- or carboplatin-based chemotherapy after approval of maintenance ICI in the Netherlands, 40.7% and 19.7% received second-line ICI, and 9.3% and 14.1% received maintenance ICI, respectively. ICI use for mBC treatment has not increased considerably since their introduction in 2017. Future research should assess whether the introduction of maintenance avelumab (available since April 2021 in the Netherlands) has led to increases in the proportion of patients with mBC patients receiving systemic treatment and the proportion receiving ICI. Patient summary: We assessed the rate of immunotherapy use for patients with metastatic bladder cancer in the Netherlands. Since its introduction, immunotherapy has been used in a minority of patients, mostly as second-line treatment after platinum-based chemotherapy.

Toxicity, disease management and outcome of treatment with immune checkpoint inhibitors by sex in patients with cancer and preexisting autoimmune disease.

Female sex is associated with a higher risk for autoimmune diseases (ADs) and immune-related adverse events (irAEs) from immune checkpoint inhibitors (ICIs). While the safety of ICIs in AD cohorts has been reported, sex-segregated data on patient characteristics and outcomes are lacking. In the present study, the disease and treatment characteristics of 51 patients with cancer and preexisting AD (PAD) treated with ICIs at Bern University Hospital Cancer Center (Bern, Switzerland) between January 2017 and June 2021 were analyzed by sex. Rheumatic (n=12/27, 44.4%) and endocrine (n=11/24, 45.8%) PADs were most common among male and female patients, respectively. At the time of ICI initiation, 29.6% (n=8/27) of male and 20.8% (n=5/24) of female patients received immunosuppression for their PAD. Female patients were more likely to experience an irAE (58.3 vs. 48.1%), and less likely to encounter an exacerbation of their PAD (38.5 vs. 14.3%) compared with male patients. Multiple-site irAEs (46.2 vs. 21.4%), implication of an organ specialist for irAEs (100.0 vs. 57.1%) and use of additional immunosuppressive drugs (38.4 vs. 7.7%) were more common in male patients. IrAEs were resolved and ICIs were discontinued in 69.2% (n=9/13) and 71.4% (n=10/14) of the total male and female patients, respectively. Median progression-free survival was higher in male than female patients with irAEs (19.9 vs. 10.7 months) and without irAEs (4.4 vs. 1.8 months). The median overall survival time was higher in male than female patients with irAEs (not estimable vs. 22.5 months) and without irAEs (10.1 vs. 7.4 months). Taken together, these results suggested that sex-related differences existed regarding the clinical presentation of irAEs and treatment outcome.

The Role of Immune Checkpoint Inhibitors in Metastatic Pancreatic Cancer: Current State and Outlook.

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest tumors, characterized by its aggressive tumor biology and poor prognosis. While immune checkpoint inhibitors (ICIs) play a major part in the treatment algorithm of various solid tumors, there is still no evidence of clinical benefit from ICI in patients with metastatic PDAC (mPDAC). This might be due to several reasons, such as the inherent low immunogenicity of pancreatic cancer, the dense stroma-rich tumor microenvironment that precludes an efficient migration of antitumoral effector T cells to the cancer cells, and the increased proportion of immunosuppressive immune cells, such as regulatory T cells (Tregs), cancer-associated fibroblasts (CAFs), and myeloid-derived suppressor cells (MDSCs), facilitating tumor growth and invasion. In this review, we provide an overview of the current state of ICIs in mPDAC, report on the biological rationale to implement ICIs into the treatment strategy of pancreatic cancer, and discuss preclinical studies and clinical trials in this field. Additionally, we shed light on the challenges of implementing ICIs into the treatment strategy of PDAC and discuss potential future directions.

Cancer researchers' perceptions of the importance of the sex of cell lines, animals, and human samples for cancer biology research.

Sex differences in cancer risk and outcome are currently a topic of major interest in clinical oncology. It is however unknown to what extent cancer researchers consider sex as a biological variable for their research. We conducted an international survey among 1243 academic cancer researchers and collected both quantitative and qualitative data. Although most of the participants indicated that they were familiar with the concept of studying sex differences in cancer biology, they did not think it was important to investigate sex differences in every context of cancer research nor in all tumor types. This is in stark contrast to the current recommendations and guidelines and illustrates the need for increased awareness among cancer researchers regarding the potential impact of the sex of cell lines, animals, and human samples in their studies.

The role of immune checkpoint inhibitors in clinical practice: an analysis of the treatment patterns, survival and toxicity rates by sex.

PURPOSE: Our aim is to describe the role of immune checkpoint inhibitors (ICI) in clinical practice by providing the patient and tumor characteristics as well as survival and toxicity rates by sex. METHODS: We used electronic health records to identify patients treated at the Cancer Center of the University Hospital Bern, Switzerland between January 1, 2017 and June 16, 2021. RESULTS: We identified 5109 patients, 689 of whom (13.5%) received at least one dose of ICI. The fraction of patients who were prescribed ICI increased from 8.6% in 2017 to 22.9% in 2021. ICI represented 13.2% of the anticancer treatments in 2017 and increased to 28.2% in 2021. The majority of patients were male (68.7%), who were older than the female patients (median age 67 vs. 61 years). Over time, adjuvant and first line treatments increased for both sexes. Lung cancer and melanoma were the most common cancer types in males and females. The incidence of irAEs was higher among females (38.4% vs. 28.1%) and lead more often to treatment discontination in females than in males (21.1% vs. 16.8%). Independent of sex, the occurrence of irAEs was associated with greater median overall survival (OS, not reached vs. 1.1 years). Female patients had a longer median OS than males (1.9 vs. 1.5 years). CONCLUSIONS: ICI play an increasingly important role in oncology. irAEs are more frequent in female patients and are associated with a longer OS. More research is needed to understand the association between patient sex and toxicity and survival.

Perioperative Chemoimmunotherapy With Durvalumab for Muscle-Invasive Urothelial Carcinoma: Primary Analysis of the Single-Arm Phase II Trial SAKK 06/17.

PURPOSE: The integration of immunotherapy in the perioperative setting of muscle-invasive urothelial carcinoma (MIUC) appears promising. SAKK 06/17 investigated the addition of neoadjuvant durvalumab to gemcitabine/cisplatin (GC) chemotherapy followed by radical surgery and adjuvant checkpoint inhibition with durvalumab. PATIENTS AND METHODS: SAKK 06/17 was an investigator-initiated, open-label, single-arm phase II study including cisplatin-fit patients with stage cT2-T4a cN0-1 operable MIUC. Four cycles of neoadjuvant GC in combination with four cycles of durvalumab (start with GC cycle 2) were administered, followed by radical surgery. Adjuvant durvalumab was given for 10 cycles. The primary end point was event-free survival (EFS) at 2 years. RESULTS: Sixty one patients were accrued at 12 sites. The full analysis set consisted of 57 patients, 54 (95%) had bladder cancer. Median follow-up was 40 months. The primary end point was met, with EFS at 2 years of 76% (one-sided 90% CI [lower bound], 67%; two-sided 95% CI, 62 to 85). EFS at 3 years was 73% (95% CI, 59 to 83). Complete pathologic response in resected patients (N = 52) was achieved in 17 patients (33%), and 31 (60%) had pathologic response

Prescription Patterns, Recurrence, and Toxicity Rates of Adjuvant Treatment for Stage III/IV Melanoma-A Real World Single-Center Analysis.

Approved adjuvant treatment options for stage III melanoma are the immune checkpoint inhibitors (ICI) pembrolizumab and nivolumab, and in presence of a BRAF V600E/K mutation additionally dabrafenib in combination with trametinib (BRAFi/MEKi). This study aims to describe prescription patterns and recurrence and toxicity rates of adjuvant-treated melanoma patients from the Cancer Center of the University Hospital Bern, Switzerland. One hundred and nine patients with an indication for adjuvant treatment were identified. Five (4.6%) had contraindications and, as such, were not proposed any adjuvant treatment, while 10 patients (9.2%) declined treatment. BRAF status was known for 91 (83.5%) patients. Of 40 (36.7%) patients with BRAF V600E/K melanoma, pembrolizumab was prescribed to 18 (45.0%), nivolumab to 16 (40.0%), and dabrafenib/trametinib to three (7.5%) patients. Grade 3-4 toxicity was reported in 18.9% and 16.7% of all the patients treated with pembrolizumab and nivolumab, respectively. No toxicities were observed for dabrafenib/trametinib. Thirty-eight percent of the patients treated with pembrolizumab and 40.0% of those treated with nivolumab relapsed. No relapses were reported for dabrafenib/trametinib. Prescription patterns indicate a clear preference for adjuvant ICI treatment.
