Single agent vs combination immunotherapy in advanced melanoma: a review of the evidence.

PURPOSE OF REVIEW: The aim of this review is to outline the current landscape of advanced melanoma treatment options, provide insights on selecting combination therapies within different clinical scenarios, capture clinical relevance of anti-programmed cell death protein 1 (PD-1) monotherapy, and explore the unmet needs with immune check-point inhibitors (ICI) in advanced melanoma. RECENT FINDINGS: ICI based treatment consisted of single agent ICI or dual combination ICI-ICI is the standard of care of front-line treatment of metastatic or unresectable melanoma. PD-1 inhibitors (Pembrolizumab and Nivolumab) improved progression free survival (PFS) and overall survival (OS) compared to chemotherapy and cytotoxic T-lymphocyte associated protein 4 (CTLA-4) inhibitors (Ipilimumab and Tremelimumab). The dual ICI combination (Nivolumab and Ipilimumab) provided profound and durable responses better than monotherapy, and the longest overall survival ever achieved in advanced disease, including in patients with murine sarcoma viral oncogene homolog B (BRAF)-mutated disease, but at the cost of a high risk of severe toxicity. The new dual blockage of LAG-3 and PD-1 (Nivolumab-Relatlimab) emerges as a valid option with promising efficacy outcomes and a favourable toxicity profile. Mature survival data is still needed to capture the real benefit. SUMMARY: These new plethora of options pose new challenges not only for optimal treatment sequencing strategies but especially for management of adverse effects, endorsing the need to integrate a holistic and personalized approach for patient care.

Pazopanib-induced trismus in a young male with metastatic renal cell carcinoma: a case report and literature review.

The treatment landscape of advanced kidney cancer has radically changed over the years. Targeting tumor angiogenesis from historical cytokines to multi-tyrosine kinase inhibitors and recently the advent of immunotherapy resulted in a radical improvement in survival but presented substantial challenges in terms of toxicity management. In countries where the access to immune checkpoints inhibitors is still very limited, tyrosine-kinase inhibitors remain the optimal choice. The toxicity profile of these agents can influence both the clinician and the patient's preference for one molecule over another. This report describes the case of a young man treated with Pazopanib in a first-line setting for stage IV renal carcinoma who developed trismus under treatment. The occurrence of this off-target toxicity has made the patient ineligible for anti-angiogenic drugs. Although side effects of tyrosine kinase inhibitors seem manageable and reversible, some less known and unusual effects may evolve into severe and irreversible complications.

What does it take to conduct clinical trials in African countries? Insights from Morocco.

The progress on cancer diagnosis and treatment has attained, in the last decade, enormous achievements by any estimate. Immunotherapy, new generations of targeted therapies, Chimeric antigen T-cells, cancer vaccines and the fascinating breakthroughs in translational research and cancer biology have changed the direction of cancer care. However, the fact that all patients worldwide cannot have access to these advances is dramatic. Alongside this, taking part in clinical research is one way to improve and invest in cancer care. Patients from African-and most low-resources countries-are rarely offered the chance of being included in clinical trials. This well-known fact paints a disheartening picture of what having cancer is like in the poorest settings. This situation will further decline with population aging, major changes in risk profile imported from developed countries and life expectancy increasing in most African countries. If no radical changes are made, this North-South contrast will become more critical and continue to grow. Yet, there is room for hope because only when we acknowledge the problem can we begin to address it. We need a better understanding of the reasons behind this gap and to advocate for more representation from African patients in clinical trials, with respect to the socio-economic, epidemiological and unique demands of each country across the continent.

Incidence Trends of Cancer in Morocco: The Tale of the Oncological Center of Marrakech (Morocco) over 8 Years.

Background: Determining cancer incidence and mortality is a key factor in the implementation of health policies and cancer prevention strategies. This report aims to describe the trends of cancer incidence in a single referral oncology department from the Marrakech region (Morocco). Material and Methods. All new cancer cases of age ≥ 15 years registered at the Medical Oncology department of Mohammed VI University Hospital of Marrakesh between January 1, 2012, and December 31, 2019, were included. Central nervous system (CNS) cancers, tumors of hematopoietic and lymphoid tissues, and thyroid cancers for which chemotherapy was not indicated or was managed in other cancer-specialized departments were excluded from the analysis. Manual data collection from printed archived medical records of the study population was performed. Descriptive statistics were analyzed using R software and Joinpoint Regression Program. Results: A total of 15648 new cancer cases were analyzed. Missing data (n = 1822) accounted for 11.64%, and 4.1% (n = 652) were excluded. The final statistical analysis and registration included 13174 cases. The median age at diagnosis is 54 years for females and 61 years for males. Female patients outnumbered males with a ratio of 1.58 among all age groups except those aged ≥75 y. The age-standardized incidence rate (ASIR) for all sites was 68,0 per 100.000 person-years, which has increased with an annual percent change (APC) of 10.61%. The five most common malignancies among males are lung, stomach, prostate, colic, and rectal cancers. Among females, the five most frequent cancers are breast, cervix, ovary, colon, and stomach. Conclusion: The higher incidence observed in our results translates into a growing burden on the center and is expected to impact our ability to deliver cancer care. Epidemiological studies to identify risk factors and effective efforts are needed to further invest in cancer control and prevention plans.

Managing cancer care during the COVID-19 pandemic: brief report from a North African single center.

The potential threat of COVID-19 pandemic on the continuity of care for cancer patients is thought to be significant. Oncologists are weighing up the balance of risks and benefits carefully when planning daily cancer care and making treatment decisions in the face of rapid change during this public health crisis. This report describes management strategies and care models that have been adopted by a single Medical Oncology department in a North Africa, Morocco.
