Management of patients with high-risk and advanced prostate cancer in the Middle East: resource-stratified consensus recommendations.

PURPOSE: Prostate cancer care in the Middle East is highly variable and access to specialist multidisciplinary management is limited. Academic tertiary referral centers offer cutting-edge diagnosis and treatment; however, in many parts of the region, patients are managed by non-specialists with limited resources. Due to many factors including lack of awareness and lack of prostate-specific antigen (PSA) screening, a high percentage of men present with locally advanced and metastatic prostate cancer at diagnosis. The aim of these recommendations is to assist clinicians in managing patients with different levels of access to diagnostic and treatment modalities. METHODS: The first Advanced Prostate Cancer Consensus Conference (APCCC) satellite meeting for the Middle East was held in Beirut, Lebanon, November 2017. During this meeting a consortium of urologists, medical oncologists, radiation oncologist and imaging specialists practicing in Lebanon, Syria, Iraq, Kuwait and Saudi Arabia voted on a selection of consensus questions. An additional workshop to formulate resource-stratified consensus recommendations was held in March 2019. RESULTS: Variations in practice based on available resources have been proposed to form resource-stratified recommendations for imaging at diagnosis, initial management of localized prostate cancer requiring therapy, treatment of castration-sensitive/naïve advanced prostate cancer and treatment of castration-resistant prostate cancer. CONCLUSION: This is the first regional consensus on prostate cancer management from the Middle East. The following recommendations will be useful to urologists and oncologists practicing in all areas with limited access to specialist multi-disciplinary teams, diagnostic modalities and treatment resources.

[Chemotherapy in the elderly: how and for whom?]. / Chimiothérapie chez le sujet âgé: quelles modalités? Quelles implications?

Management of cancer in the older-aged patient is an increasingly common problem in our occidental societies. Cancer is a disease primarily of older persons: over 60% of all cases of cancer are diagnosed after age 65 - an age group that constitutes less than 20% of the western population and the risk of persons over 65 years of age developing cancer is at least 10 times that of those under 65. Cancer in older persons may be considered a different disease from cancer in the younger in that way that biology of the host could influence the growth of cancer, that the management of the disease deserved an individualized approach. Indeed, the normal process of aging is associated with a progressive age-related reduction in function of many organs, including losses such as renal, pulmonary, cardiac, immune, hepatic, haematological, muscles, osseous, sight, hearing and brain functions. The consequences of these changes with age, added to comorbid diseases, have major implications on toxicities of anti-cancer therapies, surgery, radiotherapy as well as chemotherapy. However chronologic age should not be used as a guide to cancer therapy. Performance status and physiologic performance of the older patient are of prime importance to decide and conduct chemotherapy.

[Anticancer chemotherapy in the elderly: a review of the literature]. / Chimiothérapies anticancéreuses et personnes âgées: revue de la littérature.

Few elderly cancer patients are included in clinical trials, resulting insuffisant data of the effectiveness and tolerance of anticancer drugs in this patient population. The aim of this study was to analyse the studies concerning the effectiveness and tolerance of chemotherapy prescribed for elderly patients treated for colorectal, breast and lung cancer. The data of this population showed that the older patients are less likely to receive chemotherapy than the younger. The age is considered as significant important factor for the decision of chemotherapy of this population. However elderly patients seem to have the same benefit as compared with younger patients. Rather than the criteria of age, comorbidities should be considered. It is necessary to develop specific geriatric assessment and development of clinical trials specifically including elderly patients remains a necessity.

[Anti-angiogenic treatment and colorectal cancer]. / Traitement anti-angiogénique et cancer colorectal.

For many years, oncology research has focused on the study of therapeutic agents able to target a different cell than a cancer cell. Tumor angiogenesis mediated by the vascular endothelial growth factor (VEGF) was one of the pathways investigated. The treatment of metastastic colorectal cancer has dramatically evolved. Overall survival has significantly improved, owing to the use in standard daily practice of irinotecan and oxaliplatin, combined with 5-fluorouracil (5FU) and leucovorin. This review summarizes efficacy and safety data of two antiangiogenic agents, bevacizumab (a monoclonal antibody inhibiting VEGF) and vatalanib (a tyrosine kinase inhibitor of VEGF), assessed in phase III trials in metastastic colorectal cancer. The efficacy of bevacizumab combined with 5FU-leucovorin +/- irinotecan based on overall survival data which was demonstrated in the first-line treatment of metastastic colorectal cancer in studies conducted in the US, has recently been demonstrated in the same indication based on progression survival when combined to oxaliplatin and a fluoropyrimidine (capecitabine or 5FU-leucovorin). Bevacizumab combined to infusion chemotherapy with 5FU-leucovorin with or without irinotecan is indicated, in Europe, in the first-line treatment of metastastic colorectal cancer. While in the US, prescription options are wider in the first-line treatment, it is combined to chemotherapies with a fluoropyrimidine +/- irinotecan or oxaliplatin, and in second line as well with fluoropyrimidine and oxaliplatin. Several questions regarding the optimal use of bevacizumab still remain to be answered in the treatment of metastastic colorectal cancer. Vatalanib has not shown benefit in this pathology.
