ABSTRACT
BACKGROUND: Bladder cancer (BC) is the most common malignant tumor of the urinary tract and the 11th most frequent cancer worldwide. BC is the 2nd most common cancer in Lebanon in men and women. MATERIALS AND METHODS: After searching for patients records in the pathology and oncology database, we identified those who underwent a cystectomy between 2017 and 2019 in our hospital, Hotel Dieu de France - Beirut. We selected for the study the patients who have undergone a cystectomy for MIBC. We excluded patients who initially had a pelvic tumor, or a prostate cancer invading the bladder, and patients with absent medical record from the study. We also noted the gender of the patients, if they are smokers and the number of pack years at the time of diagnosis, as well as their age, the histological type of the tumor, its stage according to the TNM classification and its grade. We also noted whether neoadjuvant chemotherapy was taken by the study 's subjects. RESULTS: The total number of patients who met the inclusion and exclusion criteria was 38. The median age of the population was 66 (± 10) years and the median number of pack years at diagnosis was 60 (± 36). 79% of study 's patients were males and 21% were females. Regarding the tumor 's histological type, the urothelial type predominated with 92% while the remaining 8% were of the squamous type. Regarding treatment modalities, only 20% of patients in the study received neoadjuvant chemotherapy before cystectomy. 80% of patients underwent a cystectomy directly without neoadjuvant and/or adjuvant chemotherapy. No patient received adjuvant chemotherapy. Among the 7 patients, 2 patients (29%) presented a pathological complete response (pCR; equivalent to pT0N0M0). 14% had a pT3 stage post-neoadjuvant chemotherapy and 43% had a pT4 stage. DISCUSSION AND CONCLUSIONS: We can note a reluctance of urologists at our institution to prescribe neoadjuvant chemotherapy. It would therefore be interesting to extend the study to the national level with a larger number of patients, as well as to evaluate survival in patients who received neoadjuvant chemotherapy, especially in those presenting a pCR. Our study can serve as a point of change in the practice of urologists in Lebanon regarding BC.

Introduction: Patients undergoing cancer treatment as well as cancer survivors commonly describe behavioral alterations. As a matter of fact, neuropsychiatric adverse events (NPAEs) have been extensively described with older immunotherapies, especially with interferon alfa. However, there are little data investigating the NPAEs of immune checkpoint inhibitors (ICIs). Therefore, the aim of this study is to evaluate the safety profile of ICI in terms of NPAEs. Materials and Methods: This is a prospective, interventional, self-controlled study. Participants receiving ICIs as unique therapy, between February and December 2019, were evaluated at the beginning of their treatment protocol, at 1 month and finally at 3 months. During the three evaluations, disease and patients' characteristics were assessed, as well as NPAEs using the Brief Psychiatric Rating Scale (BPRS) questionnaire, the psychological stress due to cancer's burden using the Herth hope index, and the performance status (PS) using the Eastern Cooperative Oncology Group (ECOG) score. Results: Forty-four patients were enrolled, of whom 24 patients completed their three evaluation visits. No changes in BPRS total score were found throughout the study period. However, two subscores of the BPRS, "motor retardation" (P = 0.008) and "tension" or "nervousness" (P = 0.002), increased starting the 1st month of treatment. Moreover, age (r = 0.426, P = 0.038) and the baseline PS (P = 0.027) were the main risk factors of such manifestations. Conclusion: This study suggests that ICI could be responsible for motor retardation and increased tension starting the 1st month of treatment, with higher ECOG score and older age being the main risk factors.

BACKGROUND: Basal cell carcinoma (BCC) represents by far the most common non-melanoma skin cancer (NMSC) in the world with an increasing incidence of 3% to 10% per year, especially in patients under the age of 40. While variants in the sonic Hedgehog and cell cycle regulation pathways account for the majority of BCC cases in adults, the molecular etiology of BCC in young patients is unelucidated yet. This study aims to investigate the molecular profile of BCC in the young population. METHODS: 28 tumors belonging to 25 Lebanese patients under the age of 40, presenting different stages of BCC and diagnosed at Hôtel Dieu de France-Saint Joseph University Medical Center were included in this study. A selected panel of 150 genes involved in cancer was analyzed by Next Generation Sequencing (NGS) in the 28 included tumors. RESULTS: Genetic variants detected in more than 5% of the reads, with a sequencing depth ≥ 50x, were selected. Two hundred and two genetic variants in 48 different genes were detected, with an overall average sequencing depth of 1069x. Among the 28 studied tumors, 18 (64.3%) show variations in the PTCH1 gene, 6 (21.4%) in TP53 and 3 (10.7%) in SMO. CONCLUSIONS: This is the first study reporting NGS-based analysis of BCC in a cohort of young patients. Our results highlight the involvement of the hedgehog and cell cycle regulation pathways in the genesis of BCC in the general population. The inclusion of a larger cohort of young patients is needed to confirm our findings.

Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia. Chromosomal abnormalities are reported to play important roles in CLL pathogenesis and evolution, including deletions of 11q, 13q, 17p, and trisomy12, that are frequently observed and have a known prognostic value. Furthermore, the mutational status of the IGHV gene was reported as an independent prognostic marker in CLL impacting the choice of therapy. We herein, report an unusual presentation of a Lebanese CLL patient with two cytogenetic abnormalities: trisomy 12 and t(14;18)(q32;q21), along with an unmutated IGHV, displaying a favorable response to ibrutinib with a maintained complete remission.
ABSTRACT
Metastatic colorectal cancer is the second most common cause of cancer death. Standard chemotherapy in combination with targeted therapies represent the backbone for the treatment of advanced disease. However, options are limited for patients progressing on these regimens. Genetic testing can offer patients the opportunity to benefit from novel therapies, namely immune checkpoint inhibitors in microsatellite instability-positive tumors. HER2 overexpression has recently emerged as a potentially targetable tumor marker in colorectal cancer (CRC). Despite the absence of approvals for anti-HER2 therapies in CRC, many agents such as trastuzumab and pertuzumab were tested and demonstrated significant antitumor activity, even in heavily pretreated patients. Early trials are also evaluating lapatinib, T-DM1, tucatinib and other anti-HER2 agents in patients with metastatic CRC, with promising results.

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic led to a worldwide medical crisis, affecting mostly immunocompromised patients, such as cancer patients. Various cancer societies have issued recommendations regarding patients care, but few studies addressed the perception of cancer patients regarding this pandemic. OBJECTIVE: The aim of the study was to assess the perception of cancer patients regarding their health risks during this pandemic and the preventive measures taken. MATERIALS AND METHODS: An anonymous survey was conducted among cancer patients presenting for their treatment, during 10 consecutive working days, at the one-day clinic of Hotel-Dieu de France University hospital in Beirut. We evaluated their state of disease, comorbidities, precautions taken, and their concerns regarding the virus spread. RESULTS: A total of 216 patients responded with a mean age of 60 years. The majority had a good performance status (performance status = 0-1 in 79.6%), 51.4% had metastatic disease, and chemotherapy was the main therapy used (65.7%). A total of 52.3% of patients considered themselves to be at increased risk of contracting the virus. A total of 55.1% were more worried about the coronavirus rather than their disease. The priority was for the treatment of their cancer in 47.7% of the total patients studied. Of note, only 2.8% of planned one-day clinic reservations were canceled or postponed to avoid COVID-19 exposure. CONCLUSIONS: Although cancer is a disease with a high mortality rate, many patients are more concerned about the actual pandemic rather than their disease. Nevertheless, the absenteeism from their treatment sessions during the COVID-19 atmosphere was minimal.

INTRODUCTION: Medical hypnosis has received an increasing attention during the past decades. Various applications of hypnosis can be incorporated into the oncology field. This study aims to assess the knowledge of Lebanese medical oncologists on the use of hypnosis in the management of cancer patients. MATERIAL AND METHODS: An anonymous questionnaire was sent to all Lebanese medical oncologists to assess their knowledge, opinion and understanding of hypnosis and its use in oncology, as well as the obstacles facing its application in Lebanon. RESULTS: Hundred and three Lebanese medical oncologists responded to the survey, with a response rate of 65%. The findings revealed that most oncologists had little or no knowledge about hypnosis, but recommended it due to the benefits they believed it provided for the patients in improving chronic pain, invasive procedures, chemotherapy-induced nausea and anxiety. Around 40% of participants were interested in receiving a training in hypnosis. Lebanese oncologists also described many obstacles to the practice of hypnosis, mainly the lack of training for this technique and the lack of financial resources. CONCLUSION: Despite all obstacles, the majority of Lebanese oncologists would recommend hypnosis to their patients in order to improve their quality of life.

Acute myeloid leukemia (AML) is characterized by chromosomal abnormalities affecting both prognosis and course of treatment. While most AML patients have well described chromosomal aberrations, around 10% present with rare chromosomal abnormalities. We herein, report a rare balanced translocation t(12;19)(q13;q13) in a 66-year old M5-AML patient identified by Conventional cytogenetic analysis and confirmed by SNP array. We suggest that t(12;19) as a sole chromosomal abnormality could be associated with a poor prognosis. Further studies are needed to understand the molecular basis of this translocation in AML.
ABSTRACT
Debulking surgery associated with chemotherapy represent the backbone of ovarian cancer therapy. Adding bevacizumab has improved survival. Recently, PARP inhibitors were added in the first line as maintenance treatment for the patients who achieve a complete or partial response. These drugs act by blocking the activity of the PARP enzyme responsible for base-excision repair, and have shown positive responses when used for tumors lacking homologous recombination. Olaparib, niraparib and veliparib were evaluated and showed an increase in the duration of progression-free survival: 22.1 months (hazard ratio [HR] = 0.59), 13.8 (HR = 0.62) and 23.5 (HR = 0.68) with olaparib, niraparib and veliparib, respectively. This review describes the benefit of PARP inhibitors as maintenance therapy and discusses the efficacy according to breast cancer gene and homologous recombination status.

The evolution of precision medicine in the field of oncology has led to a radical change in the course of malignancies. PARP inhibitors are drugs that block the activity of the PARP enzyme responsible for base excision repair and have shown significant positive response when used for tumors lacking homologous recombination, namely high efficacy among BRCA-mutated tumors. Since 2014, when olaparib received an accelerated US FDA approval in ovarian cancer, we witnessed many other FDA approvals for olaparib, rucaparib, niraparib and talazoparib. Additionally, many Phase I, II and III trials were published presenting revolutionizing results. Other ongoing trials combined PARP inhibitors with checkpoint inhibitors. We aimed in this review to state the FDA approvals for PARP inhibitors in breast, ovarian, fallopian tube and primary peritoneal cancers, report the major published trials in high impact medical journals, and mention the ongoing trials combining these drugs with checkpoint inhibitors.

In women presenting with an abdominal mass and ascites, the first diagnosis to consider is ovarian cancer. However, clinicians should always consider alternative differentials, namely, peritoneal tuberculosis, especially in the presence of respiratory symptoms and with the increasing prevalence of extrapulmonary tuberculosis. Peritoneal tuberculosis can mimic the clinical presentation of ovarian cancer, and on imaging, it can show similar features of peritoneal carcinomatosis and nodules. Tumor markers can also be elevated in the absence of malignancy. We present the case of a 44-year-old woman with abdominal distension and ascites. Imaging with CT scan, MRI, and PET scan were inconclusive, showing peritoneal nodules. Cytology of ascites was negative. Laparoscopy was done showing Koch bacilli followed by pulmonary sampling showing Mycobacterium tuberculosis. The patient was treated with quadritherapy with resolution of symptoms.
ABSTRACT
The use of immune checkpoint inhibitors has been approved in the advanced and metastatic setting for many types of solid tumors. Nonetheless, their role in the adjuvant setting is limited to the treatment of surgically resected melanoma. Ipilimumab was the first immune checkpoint inhibitor approved for this indication, followed by nivolumab and pembrolizumab. Many ongoing trials are evaluating these molecules in the postoperative setting, alone or in combination with other therapies. Preliminary results are promising regarding the treatment of other cutaneous tumors, lung cancers, head and neck squamous cell carcinomas, bladder cancer and renal cell carcinomas. Some data assessing their use for the adjuvant treatment of esophageal, colorectal, ovarian cancer and other solid tumors are similarly emerging.

Triple-negative breast cancer (TNBC) is known to have a poor prognosis and limited treatment options, namely chemotherapy. Different molecular studies have recently classified TNBC into different subtypes opening the door to potential new-targeted treatment options. In this review, we discuss the current standard of care in the treatment of TNBC in the neoadjuvant, adjuvant and metastatic settings. In addition, we summarize the ongoing phase III clinical trials evaluating different associations between the 3 pillars of anticancer treatment: chemotherapy, targeted therapy and immunotherapy.
ABSTRACT
Introduction: Obesity is increasing worldwide and in Lebanon with a negative impact on the quality of life. The primary objective of this study is to measure the quality of life in obese subjects before and after bariatric surgery, depending on age, sex, and degree of weight loss. A secondary objective is to determine the impact of bariatric surgery on comorbidities associated with obesity. Materials and methods: Patients undergoing laparoscopic sleeve gastrectomy for BMI ≥ 30 kg/m2 between August 2016 and April 2017 were included. Participants completed the Moorehead-Ardelt Quality of Life Questionnaire II (MA II) prior to operation and one year after. Statistical analysis was carried out using SPSS statistics version 20.0. Results: 75 patients participated in the study. The majority were women (75%), and the mean age was 36.3 years. The mean weight loss was 36.57 kg (16-76). Initially, the total MA II score was -0.33 ± 0.93. Postoperatively, it increased to 1.68 ± 0.62 (p ≤ 0.001). All MA II parameters improved after surgery (p ≤ 0.001), but this improvement was independent of age and sex. Improvement in self-esteem, physical activity, work performance, and sexual pleasure was influenced by the degree of weight loss (p ≤ 0.001). All comorbidities associated with obesity regressed significantly after sleeve gastrectomy (p < 0.05) with the exception of gastroesophageal reflux and varicose veins of the lower limbs. Conclusion: Sleeve gastrectomy improves quality of life and allows reduction of comorbidities.
