Clinical and genetic factors associated with anxiety and depression in breast cancer patients: a cross-sectional study.

BACKGROUND: Despite the progress in assessment and treatment of breast cancer, being diagnosed with it or receiving chemotherapy treatment is still conceived as a traumatic experience. Women develop negative thoughts about life and death with detrimental effects on their daily physical functioning/activities, emotional state and overall quality of life. The aim of our study was to evaluate the level of anxiety and depression among breast cancer patients receiving chemotherapy and explore the correlation between these psychological disorders, clinical, sociodemographic and genetic factors. METHODS: A cross-sectional study was conducted among breast cancer patients undergoing intravenous chemotherapy at the oncology outpatient unit of Hôtel-Dieu de France hospital (November 2017-June 2019; Ethical approval number: CEHDF1016). All patients gave their written informed consent and completed several validated scales, including the Hospital Anxiety and Depression scale (HADS) for the assessment of anxiety and depression. Sleep quality, insomnia, cognitive function, fatigue and pain were also evaluated. Genotyping for certain gene polymorphisms (CLOCK, PER2, CRY2, OPRM1, ABCB1, COMT, DRD2) was performed using the Lightcycler® (Roche). RESULTS: A total of 112 women was included. The prevalence of depression was 43.4%, and 56.2% of the patients reported anxiety (based on the HADS classification). Multivariable analysis showed that higher cognitive scores and taking fosaprepitant were significantly associated with lower depression and anxiety scores. Moreover, being married compared to single was also associated with lower depression scores, whereas higher PSQI scores (worse sleep quality) and having the PER2 AA variant genotype compared to GG were significantly associated with higher depression scores. Finally, reporting a more severe insomnia and having the COMT Met/Met genotype were significantly associated with a higher anxiety score. CONCLUSIONS: Our study demonstrated a strong relationship between depression scores and cognitive impairment, sleep quality, marital status, fosaprepitant intake, and PER2 polymorphism, while anxiety scores were correlated to cognitive impairment, insomnia severity, fosaprepitant intake, and COMT polymorphism. The association with PER polymorphism was not previously reported. Identification of genetic and clinical risk factors for anxiety and depression would help clinicians implement an individualized management therapy aiming at preventing and alleviating the burden of these symptoms in breast cancer patients, hence improving their overall quality of life.

An observational, multicentre study of cabazitaxel in patients with metastatic castration-resistant prostate cancer previously treated with docetaxel (CAPRISTANA).

OBJECTIVES: To obtain routine clinical practice data on cabazitaxel usage patterns for patients with metastatic castration-resistant prostate cancer (mCRPC) and to describe physician-assessed cabazitaxel effectiveness, health-related quality of life (HRQoL) and safety. PATIENTS AND METHODS: CAPRISTANA was an international, observational cohort study examining cabazitaxel use for the treatment of patients with mCRPC. Effectiveness was assessed by overall survival (OS), progression-free survival (PFS), time to treatment failure (TTF) and disease control rate. HRQoL was assessed using the Functional Assessment of Cancer Therapy-Prostate questionnaire (FACT-P) and the three-level European Quality of Life questionnaire (EQ-5D-3L). Safety was assessed by adverse event (AE) reporting. RESULTS: A total of 189 patients were treated across 54 centres between April 2012 and June 2016. At baseline, 58.7% had ≥1 comorbidity, 93.7% had an Eastern Cooperative Oncology Group performance status ≤1, and 60.1% had a Gleason score at diagnosis of ≥8. Patients received a median of 6 cabazitaxel cycles; 84.7% received cabazitaxel as second-line therapy. The median OS, PFS and TTF were 13.2, 5.6 and 4.4 months, respectively. Cabazitaxel led to disease control in 52.9% of patients. HRQoL was maintained (40.3%) or improved (32.2%) in 72.5% of patients based on total FACT-P scores. Interestingly, 53.6% of patients reported pain improvement and a further 21.2% maintained pain control based on FACT-P prostate cancer-specific pain scores. The most common treatment-related grade ≥3 AEs were neutropenia (7.9%) and anaemia (2.1%). CONCLUSION: Patients in CAPRISTANA treated with cabazitaxel had similar disease outcomes and safety profiles compared with large phase III clinical trials. Most patients had maintained or improved HRQoL scores; >70% of patients had maintained or improved pain control.

Comparison of second-line treatments of recurrent and/or metastatic squamous cell carcinoma of the head and neck.

AIM: The literature lacks direct evidence comparing the different regimens evaluated in the second-line treatment of recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). METHODS: We conducted a network meta-analysis (NMA) of the randomized controlled Phase III trials reporting on the second-line drug treatment options in R/M SCCHN. RESULTS: The eligible trials included 11 regimens among which six targeted therapies, two immune checkpoint inhibitors and three chemotherapy regimens. Only nivolumab has shown statistically significant superiority over methotrexate in terms of overall survival (HR: 0.64; 95% CI: 0.43-0.96) and objective response rate (OR: 2.51; 95% CI: 1.07-5.86). CONCLUSION: Based on the efficacy and safety outcomes of this network meta-analysis, nivolumab seems the most favorable regimen inthe management of R/M SCCHN.

Evaluation of chronic kidney disease in cancer patients: is there a preferred estimation formula?

BACKGROUND: The evaluation of chronic kidney disease (CKD) in cancer patients seems to rely mostly on the Cockcroft-Gault (CG) formula or the creatinine levels to adjust treatment dosages which is a practice refuted by internists. AIMS: We evaluate the overall agreement of the CG, modification of diet in renal disease (MDRD) and CKD-epidemiology collaboration equations (CKD-EPI) equation with the newly devised Janowitz and Williams' (JW) equation. METHODS: The renal function was estimated in 235 cancer patients according to the CG, MDRD, body surface area (BSA)-adjusted MDRD, CKD-EPI, BSA-adjusted CKD-EPI and JW formulae. RESULTS: JW equation was more in agreement with CG and CKD-EPI estimations than the other equations. Taking JW equation as reference, receiver operating characteristic curve analysis showed that CG eGFR had the higher area under the curve when compared with other equations. Hierarchical cluster analysis showed more proximity between CG and JW equations than the other equations. CONCLUSION: The newly proposed JW eGFR estimation was more in agreement with CG equation than the other equations.

The role of palliative care in the last month of life in elderly cancer patients.

INTRODUCTION: One major health care issue encountered in elderly cancer patients is the alteration of the quality of life. The purpose of our study is to evaluate the administration of chemotherapy in the last month of life (CLML) and to evaluate the impact of the palliative care consult (PCC) in the elderly patients. METHODS: We conducted a retrospective observational study that included elderly patients diagnosed with an end-stage cancer and who were deceased between the 1st of January 2012 and the 31st of December 2015. Patient medical records were reviewed for patients' characteristics and management during the last month of life. RESULTS: This study enrolled 231 patients that fulfilled the eligibility criteria. CLML was administered in 91 patients (39.4 %) among which 43 patients (47.3 %) had their treatment within the last 2 weeks of life. Seventy-seven patients (33.3 %) had a palliative care consult (PCC) with a median duration of follow up of 13 days (range 2-56 days). Overall, PCC failed to decrease CLML administration, the duration of hospitalization, and ICU admissions. However, CLML administration decreased by 69 % among patients that had their PCC before receiving treatment (OR = 0.31; 95 % CI 0.15-0.63). PCC also led to a change in the pattern of treatment administered in the last month of life with less cytotoxic therapy (OR = 0.27 CI 95 % 0.09-0.9, p = 0.02) and higher rates of oral agents being prescribed (OR = 3.8; 95 % CI 1.3-11.3, p = 0.014). CONCLUSION: Our elderly patients seem to receive aggressive management similar to the general oncology population. Early PCC was shown throughout our results to decrease the aggressiveness of cancer treatment in elderly patients which seems to improve the quality of care of our patients.

Central Macular Thickness Monitoring after a Taxane-Based Therapy in Visually Asymptomatic Patients.

BACKGROUND: Taxanes are drugs used in various chemotherapeutical protocols to treat solid tumors. They have multiple systemic adverse effects, such as bone marrow suppression, alopecia, nausea, and vomiting, and may rarely cause ocular symptoms. In the past decade, a few reported cases have shown the occurrence of a cystoid macular edema with significant visual loss after the use of a taxane-based chemotherapy. The aim of this study was to compare the central macular thickness (CMT) before and after the initiation of a taxane-based therapy in visually asymptomatic patients and to elucidate the possible impact of these drugs on the vision of cancer patients. METHODS: Patients with a confirmed diagnosis of a solid tumor were screened for any ophthalmic disease before inclusion and had a baseline macular spectral domain optical coherence tomography (OCT; RTVue-100; Optovue Inc., Fremont, CA, USA) before the initiation of a taxane-based chemotherapy according to different protocols, such as 4EC-4T, 3FEC/3T, or 4TC. OCT was repeated after 4 cycles (or 3 months) of treatment, and CMT was compared to baseline. Patients presenting diabetic retinopathy, age-related macular degeneration or any condition that causes macular edema confirmed by ophthalmic examination were excluded. RESULTS: Fifty eyes of 25 patients were included; 92% of the subjects were female with a mean age of 48.52 years, 88% were diagnosed with breast cancer, 8% with esophageal cancer, and 4% with ovarian cancer. Docetaxel was the taxane administered to 92% of the patients. The received dose of docetaxel ranged between 110 and 160 mg. The other patients had paclitaxel in their protocols. No significant macular edema or drop in visual acuity were noted in any patient. Nevertheless, the mean CMT was found to be increased, particularly in the parafoveal and perifoveal areas (mean difference of +2.22 µm; p = 0.001). CONCLUSION: Taxane-based chemotherapy regimens seem to increase macular thickness, with a relative sparing of the fovea, in patients without significant macular edema. Further research is required to better explain the pathophysiology and possible impact of this phenomenon.

Treatment of cancer patients in their last month of life: aimless chemotherapy.

PURPOSE: The use of chemotherapy in the last month of life (CLML) of cancer patients is considered an aggressive approach to be avoided. We examined the practice of CLML in Lebanese cancer patients, and we investigated patient and tumor characteristics that justify this practice. To our knowledge, this is the first study describing CLML of Middle Eastern patients with advanced cancer. METHODS: We conducted this study at Hotel-Dieu de France University Hospital (HDF), Lebanon. Cases eligible for this study were all individuals diagnosed with cancer who died at HDF between the 1st of January and the 31st of December 2014. Demographic and clinical characteristics of the patients were obtained from the hospital registration records. Data concerning the management plan, primary malignancy and stage, chemo-sensitivity, line, type, and timing of chemotherapy in the last month of life were also obtained. RESULTS: Among the 130 cancer patients who were enrolled, CLML was administered to a total of 55 patients (42.3 %), of whom 26 patients (50 %) received more than one cytotoxic drug. Oral drug was only given to 9 patients (16.4 %). Interestingly, CLML increased the risk of death in the last month of life (p = 0.02), yet progression of disease constituted the major cause of death in this subgroup (54.6 %). The only variable to have statistical significant correlation with CLML was performance status (p = 0.03). The type of tumor and recent diagnosis of less than 2 months were also correlated to CLML (p = 0.03 and 0.024, respectively). CONCLUSION: The high percentage of patients receiving CLML underlines the difficulty of end-of-life discussions in patients from Middle Eastern societies. This is true in the context of a country with little availability of palliative care resources, where health policies should be more focused on incorporating palliative medicine in all medical strategies.

Validation of the EORTC QLQ-INFO 25 questionnaire in Lebanese cancer patients: Is ignorance a Bliss?

INTRODUCTION: Despite worldwide trends toward optimizing full disclosure of information (DOI), the prevailing belief that cancer diagnosis should be concealed from patients, for their own good, has endured for a substantial period of time in Middle Eastern communities. OBJECTIVES: This study would assess the reliability of the Arabic translated version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-INFO 25). The study was also designed to quantify DOI to Lebanese cancer patients and determine patient satisfaction with this DOI. Moreover, we compared the differences in the level of information among groups based on clinical and biographical variables. METHODS: A sample of patients, being treated for a variety of malignancies, was prospectively evaluated. A physician interviewed patients using the Arabic version of the EORTC QLQ-INFO 25, on the day of hospitalization for chemotherapy, before treatment was administered. RESULTS: In total 201 patients were interviewed. The translated version of the EORTC QLQ-INFO 25 showed high reliability when assessed using Cronbach's alpha coefficients for internal consistency with values scoring higher than 0.7 for all scales and the full questionnaire. There was a considerable lack of information provided to the participants with 38.8 % being unaware of their diagnosis and more than half being uninformed about the extent of their disease. Paradoxically, 86.5 % of patients expressed their satisfaction about the amount of information they received and 89.5 % believe the information provided was helpful. Further analysis showed no significant association between gender, marital status, cancer site and stage and the amount of information received. However, age and level of education were associated with DOI such as younger and more educated patients received more information. Older patients were also found to be the most satisfied with the information they received, despite having less access to information. CONCLUSIONS: Although a high proportion of patients were not properly informed about their diagnosis, the overwhelming majority were satisfied with the amount of information they received and believed it was useful, reflecting the complexity of Middle Eastern cultural influences on cancer patients' perspectives.

Prostate cancer across four countries in the Middle East: a multi-centre, observational, retrospective and prognostic study.

Prostate cancer (PC) is the second most prevalent cancer in males, with a steadily increasing incidence in the Middle East (ME). The aim of this study was to capture real-world data on the characteristics, disease progression, and treatment patterns among PC patients in the ME. This was a retrospective, observational, multi-centre study conducted across ten hospitals/research centers in Lebanon, Kingdom of Saudi Arabia, Iraq and Kuwait. Data were abstracted from medical records of 615 male patients who were diagnosed with PC between January 2012 and the site initiation date (December 2018-May 2019) and received at least one PC treatment/intervention. The observation period ranged between 84 and 88 months. Data were collected on demographics, clinical characteristics, time to progression to the subsequent clinical state or therapy (progression from localised/locally advanced PC to castration and to metastatic PC (metastatic castration-sensitive PC (mCSPC) or metastatic castration-resistant PC (mCRPC)), progression from mCSPC to mCRPC, and mCRPC patients' progression to first subsequent line of therapy), treatment patterns, and mortality. Most patients had localised/locally advanced PC (57.7%), followed by mCSPC (37.4%), and mCRPC (4.1%) at the time of inclusion in the study. Most patients were at tumours, nodes and metastases (TNM) stage IIIa (40.1%) or TNM stage IVb (27.8%) at study entry. Median time to metastatic disease, castration-resistance and next line therapy was 84 months (95% CI: 68-84), 41 months (95% CI: 30-56) and 7 months (95% CI: 0-41), respectively. The mortality rate was 3.6%. Disease progression was most common among patients with mCSPC (35.1%) or mCRPC (14.8%), and treatment discontinuation was most common among patients with mCRPC (36.6% treatments discontinued). The results show that most patients were at an advanced TNM stage at study entry, suggestive of a lack of awareness regarding PC. Disease progression was most common among patients with metastatic disease, reflecting the challenge of treating metastatic disease and highlighting the need for novel treatments.

Pharmacotherapy developments in autophagy inhibitors for bladder cancer.

INTRODUCTION: Autophagy is an intracellular process that plays a key role in the cellular homeostasis. Recently, it has been described as a potential therapeutic target in oncology, whether by activating or inhibiting its different cascades. Autophagy inhibitors interact with different molecular processes of the hallmarks of cancer. AREAS COVERED: Multiple proteins of the autophagy cascade could be aimed by specific inhibitors in many tumors, notably bladder cancer. In fact, bladder cancer has been increasing in prevalence over the last decade, and resistance to conventional treatment has been extensively reported in the literature. Autophagy inhibitors in bladder cancer have been described in preclinical studies to increase the sensitivity of the tumor to chemotherapy and radiotherapy. This paper is a review of the literature, which selected randomized trials, cohort studies, and case-control studies documenting the relationship between autophagy inhibitors and bladder cancer treatment. EXPERT OPINION: Autophagy is a promising pathway for cancer cell targeting that opens the horizons for a potential new therapeutic area in particular the multidisciplinary management of bladder cancer.

Value of chemotherapy post immunotherapy in stage IV non-small cell lung cancer (NSCLC).

BACKGROUND: Lung cancer is the number one cause of mortality among all types of cancer worldwide. Its treatment landscape has shifted from the classic chemotherapy alone to newer regimens based on the discovery of new immunotherapy and targeted therapy drugs. However, chemotherapy is still an option for treatment of advanced non-small cell lung cancer (NSCLC) after progression on immunotherapy alone or in combination with first-line chemotherapy. METHODS: This is a retrospective study based on chart review of patients diagnosed with advanced NSCLC cases who received Docetaxel as second or third line after being treated by immunotherapy and/or chemotherapy in previous lines. The data was collected from the medical records of physicians' clinics in three different hospital centers in Lebanon over the period of 5 years from July 2015 until December 2020. February 2021 was data analysis cut off time. The main aim was to assess the role of Docetaxel post-chemoimmunotherapy for patients with diagnosed NSCLC. RESULTS: A total of 21 patients were included in this study. The majority of our patients were males (81%). As for histologic type, most patients had non-squamous lung cancer (67%) as compared to 33% who had squamous lung cancer. Overall, our study reported a 24% response rate to Docetaxel including stable disease and partial response and a median progression free survival (PFS) of 3 months. The mean time interval elapsed from diagnosis to the initiation of Docetaxel was 11.5 months. CONCLUSION: New therapeutic options should be validated for the treatment of NSCLC in the second and subsequent lines of therapy considering the poor prognosis of this disease. The chemotherapy in second and third line may keep an important role in the treatment after progression on newer agents, but it needs more evidence in prospective studies including a larger number of patients.

Diagnosis and management of patients with stage III non­small cell lung cancer: A joint statement by the Lebanese Society of Medical Oncology and the Lebanese Pulmonary Society (Review).

Proper management of stage III non-small cell lung cancer (NSCLC) might result in a cure or patient long-term survival. Management should therefore be preceded by adequate and accurate diagnosis and staging, which will inform therapeutic decisions. A panel of oncologists, surgeons and pulmonologists in Lebanon convened to establish a set of recommendations to guide and unify clinical practice, in alignment with international standards of care. Whilst chest computerized tomography (CT) scanning remains a cornerstone in the discovery of a lung lesion, a positron-emission tomography (PET)/CT scan and a tumor biopsy allows for staging of the cancer and defining the resectability of the tumor(s). A multidisciplinary discussion meeting is currently widely advised for evaluating patients on a case-by-case basis, and should include at least the treating oncologist, a thoracic surgeon, a radiation oncologist and a pulmonologist, in addition to physicians from other specialties as needed. The standard of care for unresectable stage III NSCLC is concurrent chemotherapy and radiation therapy, followed by consolidation therapy with durvalumab, which should be initiated within 42 days of the last radiation dose; for resectable tumors, neoadjuvant therapy followed by surgical resection is recommended. This joint statement is based on the expertise of the physician panel, available literature and evidence governing the treatment, management and follow-up of patients with stage III NSCLC.

Consensus Recommendations for the Diagnosis, Biomarker Testing, and Clinical Management of Advanced or Metastatic Non-small Cell Lung Cancer With Mesenchymal-Epithelial Transition Exon 14 Skipping Mutations in the Middle East, Africa, and Russia.

Mesenchymal-epithelial transition exon 14 (METex14) skipping mutations occur in about 3%-4% of patients with non-small cell lung cancer (NSCLC). This is an aggressive subtype associated with poor prognosis. METex14 skipping is a potentially targetable mutation. Targeted therapy is a promising treatment modality for patients with advanced/metastatic METex14-mutant NSCLC. Performing systematic molecular testing to detect the driver mutation is essential for initiating targeted therapy. However, there is a lack of guidelines on molecular testing for assessing the eligibility of patients for targeted therapy. Therefore, a multidisciplinary panel consisting of experts from the Middle East, Africa, and Russia convened via a virtual advisory board meeting to provide their insights on various molecular testing techniques for the diagnosis of METex14 skipping mutation, management of patients with targeted therapies, and developing consensus recommendations for improving the processes. The expert panel emphasized performing molecular testing and liquid biopsy before treatment initiation and tissue re-biopsy for patients with failed molecular testing. Liquid biopsy was recommended as complementary to tissue biopsy for disease monitoring and prognosis. Selective MET inhibitors were recommended as the first and subsequent lines of therapy. These consensus recommendations will facilitate the management of METex14 skipping NSCLC in routine practice and warrant optimum outcomes for these patients.

Triple-negative breast cancer in Lebanon: a case series.

OBJECTIVES: To determine the incidence, characteristics, and survival outcomes of triple-negative breast cancer patients in a medical oncology practice in Lebanon. METHODS: The pathology reports of all breast cancer cases diagnosed or treated in 1997-2008 were reviewed. RESULTS: One hundred seventy breast cancer cases (9.3%) of the 1,834 cases that were identified in this practice over a 10-year span had a triple-negative phenotype, with a median age at diagnosis of 52 years. The pathology distribution of those cases was as follows: invasive ductal carcinoma, 85%; medullary carcinoma, 5%; invasive lobular carcinoma, 5%; 95 cases (63%) were grade III. At diagnosis, 17% presented with stage I, 47% had stage II, 24% had stage III, and 12% had stage IV disease, whereas 11% had an inflammatory component. After a median follow-up of 17 months, 43 patients (25.3%) had relapsed and the most common sites of relapse were the brain (19%), lungs (19%), and bones (12%). The risk for recurrence peaked at 1.5 years and became almost nil after 3 years. Twenty patients received induction chemotherapy, among whom six (42.9%) had a complete response and six (42.9%) had a partial response to treatment. None of the patients progressed on neoadjuvant chemotherapy. The 5-year disease-free survival rate was 75% for stage I, 58% for stage II, and 40% for stage III patients, whereas the 5-year overall survival rate was 88% for stage I, 72% for stage II, and 63% for stage III patients. Adjuvant therapy was administered to 96% of patients, using a taxane-based regimen in 38% of cases. The median survival time for stage IV patients was 19 months, with a first line taxane-based regimen used in 50% of cases. CONCLUSIONS: The incidence of triple-negative breast cancer in Lebanon is similar to that described in the literature. In order to determine targets for future therapeutic options, it is essential to understand the biology of this particular breast cancer subtype.

Management of breast cancer patients with BRCA gene mutations in Lebanon of the Middle East: perspectives and challenges.

BACKGROUND: This commentary explores and discusses the challenges oncologists face in diagnosing and managing breast cancer patients with BRCA gene mutations in Lebanon and the Middle East. METHODS: Key opinion leaders shared their recommendations to achieve better patient outcomes and satisfaction based on evidence-based medicine and their clinical experience in BRCA management. RESULTS: Challenges associated with BRCA management can be divided into four main levels: physicians, patients, test, and treatment factors. More genetic counselors are to be identified given their important role in the management of individuals with BRCA gene mutations. CONCLUSION: Genetic counseling, continuing education, infrastructure, testing, expertise, and financial support are needed to fulfill the unmet needs in the management of BRCA mutation carriers.

Impact and Cost-Effectiveness of Oncotype DX for Guiding Adjuvant Chemotherapy Decisions in Early Breast Cancer.

INTRODUCTION: Oncotype DX is approved in multiple countries but its cost-effectiveness is a matter of considerable health debate. Lebanon is high-middle income country according to the World Bank classification however it is facing a mounting financial and health care burden from cancer. Therefore, we conducted a costeffectiveness analysis of Oncotype DX based Lebanese on real-life data. METHODS: We updated a Canadian cost-effectiveness model of Oncotype DX by incorporating Lebanese data. The patient population was a real-life cohort of 82 women diagnosed with hormone receptor - positive and HER2 - negative early breast cancer. RESULTS: Overall, providing Oncotype DX to only intermediate Adjuvant! Online risk patients costs an additional $83 CAD (93,883 LBP) per additional QALY. From this point, extending provision to also cover high Adjuvant! Online risk patients costs an additional $736 CAD (831,578 LBP) per additional QALY. From this point, extending provision further to also cover low Adjuvant! Online risk patients (such that Oncotype DX is provided to all patients) costs an additional $14,562 CAD (16.46m LBP) per additional QALY. Given that most women in our population-based sample were classified as intermediate Adjuvant! Online risk patients, our study focused on this subset in the second analysis. Providing Oncotype DX to intermediate Adjuvant! Online risk patients has a relatively small additional cost compared to not providing Oncotype DX, and results in a relatively large QALY gain. The incremental cost per QALY is $2,022 CAD (2.29m LBP), implying that Oncotype DX is cost-effective for intermediate Adjuvant! Online risk patients if the willingness-to-pay for a QALY is greater than 2.29m LBP. CONCLUSION: As one of the few economic evaluations to date conducted using Lebanese data, this evaluation provides information to decision makers regarding the cost-effectiveness of providing Oncotype DX to Lebanese patients.

Impact of Commercialized Genomic Tests on Adjuvant Treatment Decisions in Early Stage Breast Cancer Patients.

INTRODUCTION: Advances in genomic techniques have been valuable in guiding decisions regarding the treatment of early breast cancer (EBC) patients. These multigene assays include Oncotype DX, Prosigna, and Endopredict. There has generally been a tendency to overtreat or undertreat patients, and having reliable prognostic factors could significantly improve rates of appropriate treatment administration. In this study, we showcase the impact of genomic tests on adjuvant treatment decisions in EBC patients. MATERIALS AND METHODS: This is a retrospective study that includes EBC patients treated between December 2016 and February 2018. The physician's choice of treatment was recorded before and after obtaining the results of the genomics tests. Baseline demographics and pathological data were collected from medical records. RESULTS: A total of 75 patients were included. Fifty patients underwent Oncotype DX genomic analysis, 11 patients underwent Prosigna analysis, and 14 patients underwent Endopredict analysis. A total of 21 physicians' plans (28%) were initially undecided and then carried out after obtaining genomic test results. 13 patients were planned to undergo endocrine therapy alone, while 8 were planned to undergo both endocrine therapy and chemotherapy. Treatment was changed in 26 patients (34.67%). The decision to deescalate therapy was taken in 19 patients (25.33%). The decision to escalate treatment was made in 7 patients (9.33%). CONCLUSION: Our study demonstrates the importance of genomics testing, as it assisted physicians in avoiding unnecessary adjuvant chemotherapy in 25.33% of patients, thus reducing side effects of chemotherapy and the financial burden on patients.

Neoadjuvant chemotherapy and Avelumab in early stage resectable nonsmall cell lung cancer.

Multiple randomized studies have shown that combination of chemotherapy and immune checkpoint inhibitors (ICIs) leads to better response rates and survival as compared to chemotherapy alone in the advanced stage of NSCLC. Data suggesting a benefit to using ICIs in the neoadjuvant therapy of patients with early stage NSCLC are emerging. Eligible subjects were treatment naïve patients with stage IB, II, and resectable IIIA NSCLC. Patients received three cycles of neoadjuvant chemotherapy with four doses of avelumab every 2 weeks. Patients with squamous cell cancer received cisplatin or carboplatin on day 1 and gemcitabine on days 1 and 8 of each cycle of chemotherapy. Patients with nonsquamous histology received cisplatin or carboplatin with pemetrexed on day 1 of each cycle. Patients then proceeded to their planned surgery. Out of 15 patients accrued as part of stage 1 of the study, four had a radiologic response (1 complete response), lower than the minimum of six responses needed to continue to phase 2 of the study. The study was therefore terminated. Majority had adenocarcinoma histology and stage IIIA disease. The treatment was well tolerated with no unexpected side effects. Four patients (26.7%) had grade III/IV CTCAE toxicity. This study confirms that the preoperative administration of chemotherapy and avelumab is safe. There was no indication of increased surgical complications. The benefit of adding immunotherapy to chemotherapy did not appear to enhance the overall response rate of patients in the neoadjuvant setting in patients with resectable NSCLC because this study failed to meet its primary endpoint.

Micropapillary bladder cancer: a review of Léon Bérard Cancer Center experience.

BACKGROUND: Micropapillary bladder cancer is a rare and aggressive variant of urothelial carcinoma. A retrospective review of our experience in management of patients with muscle-invasive or metastatic micropapillary bladder cancer was performed to better define the behavior of this disease. METHODS: We reviewed the records of the 11 patients with micropapillary bladder cancer who were evaluated and treated at Léon Bérard Cancer Center between 1994 and 2007, accounting for 1,2% of all urothelial tumors treated in this institution. RESULTS: Mean patients age was 60 years. The majority of patients (72%) were diagnosed after 2004. After a median follow-up of 31.7 months, median overall survival was 19 months. Two patients presented with stage II, one with stage III and eight with stage IV disease All 5 patients who had node positive metastases and treated with radical surgery and adjuvant chemotherapy relapsed and had a disease free survival of 9.6 months. CONCLUSION: Micropapillary bladder cancer is probably an underreported variant of urothelial carcinoma associated with poor prognosis. Adjuvant chemotherapy might have a questionable efficacy and the optimal treatment strategy is yet to be defined.

Total Parenteral Nutrition in Middle Eastern Cancer Patients at End of Life: Is it Justified?

PURPOSE: The use of total parenteral nutrition (TPN) in terminally ill cancer patients is considered an aggressive approach with very limited benefits. We examined the practice of TPN in our end of life cancer patients and we investigated the patient and tumor characteristics that justify this practice. To our knowledge, this is the first study describing TPN administration of Middle Eastern patients with advanced cancer. METHODS: We conducted this retrospective observational study at Hotel-Dieu de France University Hospital, Lebanon. Eligible cases included all cancer patients that died at our institution between the 1st of January and the 31st of December 2014. The patients and tumors characteristics were analyzed for their potential role as determinant of TPN administration. The patients' hospitalization and causes of death were evaluated for the analysis of TPN benefits. RESULTS: Among the 129 patients enrolled, 39% had received TPN among which TPN administration correlated negatively to hyperlipidemia (OR= 0.33; 95% CI [0.12-0.87]) and to the presence of at least three cardiovascular risk factors (OR= 0.28; 95% CI [0.10 - 0.80]). However, it correlated positively to gastrointestinal tumors (OR= 3.9; 95% CI [1.3- 11.7]) and to imaging studies during the last month of life (OR= 3.4; 95% CI [1.3 - 9.0]). The TPN administration did not correlate to hospitalization during the last two weeks of life. CONCLUSION: The adoption of an optimal palliative care approach in Middle Eastern cancer patients at the end of life remains challenging. Oncologists seem to consider cardiovascular risk factors as a probable surrogate to predict complications of TPN.
