In this plain language podcast, highlights from the European Society for Medical Oncology (ESMO) Congress are discussed for a second year in a row, from the perspective of both a patient advocate and a healthcare professional. The patient advocacy track at the congress included two patient-focused sessions each day on a variety of topics. Here, the authors discuss the importance of involving patients in the design of clinical trials, as well as strategies to improve dialogue and connections between clinicians, researchers and patients. Patient advocacy organisations provide essential services to patients with cancer and their caregivers, and patient advocates play a critical role in helping to inform patients and caregivers in making clinical decisions. Congresses such as ESMO provide an important platform for patient advocates to connect with each other and with physicians and researchers to ensure that patients are placed at the centre of the conversation and are up to date on the latest findings that affect them. The authors also discuss the latest research on genitourinary cancers, focusing on bladder and kidney cancer. Promising results are emerging for combination antibody-drug conjugates and immunotherapy for patients with hard-to-treat, locally advanced or metastatic bladder cancer who are ineligible for platinum-based chemotherapy. In the management of kidney cancer, we may be reaching an end for immune checkpoint inhibitors on their own; the path ahead will be to find new targets and combinations.

Introduction: The combination of doxorubicin and paclitaxel (AP) is widely used in our country for the neoadjuvant treatment of breast cancer as well as metastatic breast cancer. The AP regimen has shown promise as a neoadjuvant therapy for breast cancer that improves pathological complete response (pCR), increases the rate of conservative surgery, and improves the survival of patients. However, up to now, no research has evaluated the response of this regimen for the neoadjuvant treatment of advanced breast cancer, especially with a 10-year period of follow-up.

Methods: This retrospective analysis reviewed 126 patients with inoperable stage III breast cancer who received neoadjuvant chemotherapy with doxorubicin 50 mg/m² plus paclitaxel 175 mg/m² every 3 weeks for a maximum of six courses followed by surgery. pCR was evaluated. Survival was analyzed for all breast cancer patients using Kaplan-Meier and log-rank models.

Results: Of 126 women treated with neoadjuvant chemotherapy (NAC), the overall pCR rate was 25.4% and was significantly higher in patients with tumor stage cT1-T2, hormone receptor-negative (HR-negative), and human epidermal growth factor receptor 2 (HER2)-positive disease. Patients achieving pCR had significantly longer disease-free survival (DFS) and overall survival (OS). Ten-year DFS rates were 43.8% vs. 25.0% (p = 0.030) and 10-year OS rates were 59.4% vs. 28.9% (p = 0.003) for patients with pCR and non-pCR, respectively. The cumulative 10-year DFS was 19.6% for patients with HR-negative disease and 37.3% for those with HR-positive disease. Achieving pCR was associated with improved 10-year OS and DFS. Several clinicopathological features were closely associated with pCR in the inoperable stage III breast cancer patients who were treated by neoadjuvant chemotherapy.

Conclusion: Achieving pCR was associated with improved 10-year OS and DFS. Patients with advanced breast cancer with HR-negative and HER2-positive status who benefited from the AP neoadjuvant therapy regimen were significantly more likely to achieve pCR.

This article was co-authored by a patient's relative describing their experiences of receiving a diagnosis and subsequent clinical management of a rare form of prostate cancer, neuroendocrine prostate cancer (NEPC). The difficulty of receiving this diagnosis, particularly as this was terminal with no options for systemic treatment, and experiences throughout this process are detailed. The relative's questions regarding the care of her partner, NEPC and clinical management are answered. The treating physician's perspective regarding clinical management is enclosed. Prostate cancer remains one of the most common cancer diagnoses, with small-cell carcinoma (SCC) of the prostate representing 0.5-2% of these. Prostatic SCC frequently develops in patients previously treated for prostate adenocarcinoma, more rarely arising de novo. Diagnosis and management present clinical challenges owing to its rarity, frequently aggressive disease course, lack of specific diagnostic and monitoring biomarkers, and treatment limitations. Current pathophysiological understanding of prostatic SCC, genomics and contemporary and evolving treatment options in addition to current guidelines are discussed. Written principally from the patient's relatives and physician experience with discussion of current evidence, diagnostic and treatment options, we hope this piece is informative for both patients and healthcare professionals alike.

Introduction: There is a dearth of evidence to document treatment of FMS-like tyrosine kinase 3 (FLT3)-mutated acute myeloid leukemia (AML) in real-world settings before the introduction of FLT3 inhibitors. A retrospective cohort study was conducted to understand treatment practices prior to the availability of FLT3 inhibitors in patients with FLT3-mutated AML from two registries in France.

Methods: Patient data from January 1, 2009 to December 31, 2017 were collected from the Hauts-de-France and Midi-Pyrénées registries. Patients aged ≥ 18 years at diagnosis with FLT3-mutated AML were included. Demographic and disease characteristics of patients with FLT3-mutated AML and relapsed or refractory (R/R) FLT3-mutated AML were documented. Treatment regimens, overall survival (OS), and event-free survival were assessed in patients with R/R FLT3-mutated AML who did not participate in clinical trials.

Results: Overall, 819 and 1244 adult patients with AML from the Midi-Pyrénées and Hauts-de-France cohorts, respectively, underwent FLT3 mutation testing; 172 (21.0%) and 263 (21.1%) patients, respectively, had a FLT3 mutation. Primary R/R status was identified in 41.3% (n = 71/172) of the Midi-Pyrénées and 34.6% (n = 91/263) of the Hauts-de-France cohorts. Before R/R AML diagnosis, 82.0% and 97.5% of patients in the Midi-Pyrénées and Hauts-de-France cohorts, respectively, achieved complete remission (CR) or CR with incomplete hematologic recovery (CRi) following induction chemotherapy; after diagnosis of R/R AML, CR/CRi rates with salvage therapy were 33.3% and 28.1%, respectively. Median OS (interquartile range) in patients receiving salvage therapy (n = 49, n = 78) was 5.2 (2.3-11.1) and 6.1 (2.5-35.2) months, in the Midi-Pyrénées and Hauts-de-France cohorts, respectively. Across both cohorts, patients with R/R FLT3-mutated AML had low rates of CR/CRi with salvage therapy and a median OS of approximately 6 months.

Conclusion: Before FLT3 inhibitor availability, real-world treatment patterns and outcomes in French patients with R/R FLT3-mutated AML were consistent with clinical trial data, highlighting a poor prognosis and unmet need for effective treatment.

Introduction: Small cell lung cancer (SCLC) is a subtype of lung cancer, the second most common cancer diagnosis worldwide. Currently, there is little published qualitative research that provides insight into the disease-related symptoms and impacts that are relevant to patients living with SCLC as directly reported by patients themselves.

Methods: This qualitative, cross-sectional, noninterventional, descriptive study included concept elicitation interviews with participants diagnosed with SCLC and the development of a conceptual model of clinical treatment benefit.

Results: Concept elicitation interview data from 26 participants with SCLC were used to develop a conceptual model of clinical treatment benefit that organized 28 patient-reported concepts into two domains: disease-related symptoms (organ-specific and systemic) and impacts. Organ-specific symptoms included cough, chest pain, and difficulty breathing. Systemic symptoms included pain, fatigue, appetite loss, and dizziness. Impacts included physical functioning, role functioning, reduced movement, impact on sleep, and weight loss.

Conclusion: As evidenced by this study, people with SCLC experience considerable and significant symptoms and impacts, including physical and role functioning challenges, that affect their quality of life. This conceptual model will inform the design of a patient-reported outcome (PRO) questionnaire for a future SCLC clinical trial, helping to establish the content validity of the items and questionnaires used in the trial and ensuring that the questionnaires and items selected are appropriately targeted to the population. This conceptual model could also be used to inform future SCLC clinical trials.

Prevalence of survivors of breast cancer has been steadily increasing in the last 20 years. Currently, more than 90% of women diagnosed with early-stage breast cancer are expected to be alive at 5 years from diagnosis thanks to early detection and breakthrough innovations in multimodal treatment strategies. Alongside this advancement in clinical outcomes, survivors of breast cancer might experience several specific challenges and present with unique needs. Survivorship trajectories after diagnosis and treatment of breast cancer can be significantly impacted by long-lasting and severe treatment-related side effects, including physical problems, psychological distress, fertility issues in young women, and impaired social and work reintegration, which add up to patients' individual risk of cancer recurrence and second primary malignancies. Alongside cancer-specific sequelae, survivors still present with general health needs, including management of chronic preexisting or ensuing conditions. Survivorship care should implement high-quality, evidence-based strategies to promptly screen, identify, and address survivors' needs in a comprehensive way and minimize the impact of severe treatment sequelae, preexisting comorbidities, unhealthy lifestyles, and risk of recurrence on quality of life. This narrative review focuses on core areas of survivorship care and discuss the state of the art and future research perspectives in key domains including selected long-term side effects, surveillance for recurrences and second cancers, well-being promotion, and specific survivors' needs.

The presence of mutated genes strongly correlates with the incidence of cancer. Decades of research, however, has not yielded any specific causative gene or set of genes for the vast majority of cancers. The Cancer Genome Atlas program was supposed to provide clarity, but it only gave much more data without any accompanying insight into how the disease begins and progresses. It may be time to notice that epidemiological studies consistently show that the environment, not genes, has the principal role in causing cancer. Since carcinogenic chemicals in our food, drink, air, and water are the primary culprits, we need to look at the biochemistry of cancer, with a focus on enzymes that invariably facilitate transformations in a cell. In particular, attention should be paid to the rate-limiting enzyme in DNA synthesis, ribonucleotide reductase (RnR), whose activity is tightly linked to tumor growth. Besides circumstantial evidence that cancer is induced at this enzyme's vulnerable free-radical-containing active site by various carcinogens, its role in initiating retinoblastoma and human papillomavirus (HPV)-related cervical cancers has been well documented in recent years. Blocking the activity of malignant RnR is a certain way to arrest cancer.

Introduction: We evaluated real-world outcomes in patients with advanced ovarian cancer (AOC) based on their cumulative risk profile and maintenance therapy (MT) status following first-line (1L) treatment.

Methods: This retrospective observational study of a nationwide electronic health record-derived de-identified database included adult patients diagnosed with stage III/IV OC from January 1, 2011 to February 28, 2021, who received 1L therapy and had ≥ 12 weeks of follow-up after the index date (end of 1L therapy). Patients were grouped according to whether they received MT or active surveillance (AS) following 1L treatment and by the cumulative number of risk factors (RF) present (stage IV disease; no surgery/treated with neoadjuvant therapy and interval debulking surgery; had postoperative visible residual disease; and had BRCA wild-type disease/unknown BRCA status). Time to next treatment (TTNT) and overall survival (OS) were assessed with a cloning and inverse probability of censoring (IPC)-weighted Kaplan-Meier method.

Results: Among 1920 patients, 22.2% received MT and 77.8% received AS. Median IPC-weighted TTNT and OS were 13.3 months (95% CI 11.7-15.8) and 39.1 months (95% CI 32.5-48.6) in the MT cohort, respectively, and 8.6 months (95% CI 8.0-9.5) and 38.4 months (95% CI 36.4-41.0) in the AS cohort, respectively. Almost all patients had ≥ 1 RF (MT 95.3%; AS 96.7%). Median IPC-weighted TTNT was shorter among patients with more RF in both cohorts (MT: 1 RF, 19.3 months, 95% CI 13.5-37.8; 2 RF, 17.2 months, 95% CI 12.8-20.2; 3 RF, 11.0 months, 95% CI 8.2-13.8; 4 RF, 7.0 months, 95% CI 6.2-8.8; AS: 1 RF, 17.7 months, 95% CI 13.5-22.3; 2 RF, 10.2 months, 95% CI 9.1-11.5; 3 RF, 6.5 months, 95% CI 5.8-7.4; 4 RF, 4.1 months, 95% CI 3.5-4.5).

Conclusion: Regardless of RF number, MT was associated with longer TTNT in real-world patients with AOC.

Acute myeloid leukemia (AML) can affect individuals of all ages, but is more common in older adults. It has been estimated that AML accounted for 1% of all newly diagnosed cancers in the USA in 2022. The diagnostic process varies depending on the presenting symptoms and the healthcare facility that patients attend at diagnosis. The treatment process is long and prone to complications, requiring experienced medical professionals and appropriate infrastructure. Treatment of the disease did not change greatly over the years until 2017 when targeted therapies were licensed. The treatment of AML is associated with significant direct economic costs. A number of obstacles originating both from individual patients and the healthcare system may be encountered during the diagnosis and treatment of the disease, which may negatively impact the optimal management of the disease process. In this article, we focus primarily on the social, operational, and financial obstacles including the corona virus disease 2019 (COVID-19) pandemic experienced during the diagnosis and treatment of AML.
