Neo-adjuvant FOLFIRINOX in borderline resectable and locally advanced pancreatic adenocarcinoma.

BACKGROUND: Surgery and systemic therapy provide the best option for long-term cancer control in localized resectable pancreas cancer. The present study assessed the efficacy and safety of neoadjuvant treatment with FOLFIRINOX in patients with borderline resectable (BR) and locally advanced (LA) pancreas cancer (PDAC). METHODS: This was a prospective noninterventional observational trial of neoadjuvant FOLFIRINOX in BR and LA PDAC. The primary objective was the R0/R1 surgical resection rate. Secondary objectives included progression free survival (PFS) and overall survival (OS), tolerability, and toxicity. RESULTS: Forty-nine patients were enrolled between 2013 and 2019; the majority had LA disease (59.2%). Median age was 61 years, and median Ca 19-9 level pretreatment was 523.4 µmol/L. Following neoadjuvant FOLFIRINOX, 11 patients (22.5%) underwent surgical resection, the majority of which were BR at diagnosis (72.7%). Median OS and PFS for the entire group were 25 (95% CI: 17.2-32.8) and 12 months (95% CI: 9.7-13.3), respectively. Median PFS in BR patients was 14 (95% CI: 10.5-17.5) compared to 12 months (95% CI: 5.2-18.8) in patients with LA patients. Median OS and PFS were not reached in patients who underwent surgical resection as compared to 22 (95% CI: 18.6-25.4) and 9 months (95% CI: 4.2-13.9) in those who did not, respectively. Grade 3/4 neutropenia, leukopenia, neuropathy, nausea/vomiting, and diarrhea occurred in 6.3%, 2.1%, 10.4%, 4.2%, and 8.3%, respectively. CONCLUSION: Neoadjuvant FOLFIRINOX is an active regimen for patients with LA/BR PDAC with a resection rate of 22.5%. These results are in line with prior data.

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.

Prevalence of EGFR and ALK Mutations in Lung Adenocarcinomas in the Levant Area - a Prospective Analysis

Background: A significant percentage of lung adenocarcinomas have a driver mutation. To date, there has been no assessment of the prevalence of such mutations in a Middle Eastern population. The present multicenter prospective study of formalin fixed paraffin embedded (FFPE) tissues from patients diagnosed with lung adenocarcinoma was performed to assess the prevalence of EGFR and ALK mutations in the Levant. Methods: Patients of Middle Eastern origin with lung adenocarcinomas at 10 sites in Lebanon, Jordan and Iraq were prospectively enrolled. Tumors were tested for EGFR by PCR and for EML4-ALK translocation by fluorescence in situ hybridization (FISH). Results: A total of 210 patients were enrolled, 139 (66.2%) males and 71 females (33.8%), with a mean age of 63.4 years. EGFR testing of 205 (97.6%) demonstrated the wild type in 173 (84.4%) and mutated forms in 32 (15.6%). Some 46.9% of EGFR positive patients were non-smokers and 62.5% were females as opposed to 22.4% and 33.8%, respectively, in the general population. As for the EML4-ALK translocation, testing in 157 (74.8%) cases gave negative results in 154 (98.1%) , only 3 being positive (1.9%), 2 being females and 2 non-smokers.Conclusion: Our study established a 15.6% EGFR mutation rate in lung adenocarcinomas with ALK translocation mutations in only 1.9%, as compared to a 15-20% and 5%, respectively, in the Western literature.

Epidemiology and prognosis of breast cancer in young women.

Breast cancer is the most common malignancy in women with 6.6% of cases diagnosed in young women below the age of 40. Despite variances in risk factors, Age Standardized Incidence Rates of breast cancer in young women vary little between different countries. Review of modifiable risk factors shows that long-term use of oral contraceptives, low body mass index (BMI) and high animal fat diet consumption are associated with increased risk of premenopausal breast cancer. Decreased physical activity and obesity increase risks of breast cancer in postmenopausal women, but data on premenopausal women rather shows that high BMI is associated with decreased risk of breast cancer. Non-modifiable risk factors such as family history and genetic mutations do account for increased risks of breast cancer in premenopausal women. Breast cancer in young women is associated with adverse pathological factors, including high grade tumors, hormone receptor negativity, and HER2 overexpression. This has a significant negative impact on the rate of local recurrence and overall survival. Moreover, younger women often tend to present with breast cancer at a later stage than their older counterparts, which further explains worse outcome. Despite these factors, age per se is still being advocated as an independent role player in the prognosis. This entails more aggressive treatment modalities and the need for closer monitoring and follow-up.
