Triple-negative breast cancer (TNBC) is a heterogeneous disease on the pathological, molecular, and clinical levels. It represents approximately 17% of all breast cancers (BCs) and have aggressive behavior compared to other molecular subtypes. QNBC is TNBC that lacks the expression of androgen receptor (AR), Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) and accounts for 63%-87% of TNBC with more aggressive behavior than the other molecular subtypes (

Background:Although, efforts to encourage palliative care only for terminal patients, aggressive end-of-life care (EOL) care still common for those probably to die shortly.Aim:Multicenter experiences to investigate where did we stand in this era?Patients and Methods:A retrospective study included patients with advanced solid tumors. The presence of one or more of the following indicators in the last month of life (LM) referred to aggressive EOL care: emergency department (ED) visits ≥ twice, admission to the hospital through ED, death in critical care units (CCUs), and palliative chemotherapy (PC) at the past 2 weeks before death.Results:A total of 435 patients, 51.5% were men with a median age of 62 years (range: 17–108), were included in the study. Most of the patients (89.2%) belonged to Group II; they had attended ED at least twice (60%), approximately 53% admitted to the hospital through ED, 31% received PC-LM with 41% of them had at the past 2 weeks before death, 13% died in the CCUs, and more than half of them (53%) survived <2 weeks. Kaplan–Meier estimator revealed that median survival was 30 days in Group I versus 13 days in Group II (odds ratio: 1.63; 95% confidence interval: 1.20–2.21; P = 0.002). The median survival was statistically significantly associated with PC-LM ≥14 days and the admission mode. There was no statistically significant association with age, sex, and primary cancer sites.Conclusion:The majority of our patients continue with anticancer treatments they possibly do not need and associated with poor survival.

Resistant to hormonal treatment considered the main clinical challenge in the management of advanced breast cancer (ABC). The use of CDK4/6 inhibitors (CDK4/6I) may change the treatment landscape. In this mandated review, we will focus on the applicable role of CDK4/6I in the management of HR+/HER2- ABC, mechanisms of resistance, and promising future implementation.

Background:Due to lack of availability of gene expression profiling (GEP) for most developing countries and clinicians; the immunohistochemistry (IHC) is mostly used in the clinical application. The aim of our study is to check the possibility of using IHC to detect MYC and BCL2 in our patients with diffuse large B-cell lymphoma (DLBCL) instead of GEP to stratify them into high and low-risk groups. This will help in a proper treatment choice of subsequent improvement in the survival outcome.Method:During the study period, 90 DLBCL patients were eligible. MYC and BCL2 evaluated by IHC and gene rearrangement by real-time PCR (RT-PCR) and correlated with clinical-pathological features and survival.Results:Through IHC, the expression of MYC, BCL2, and double expression was detected in 35.6%, 46.7% and 30% of patients, respectively. While by RT-PCR, it was 4.53±0.74 for MYC compared with 2.18±0.78 for BCL-2. Most patients with BCL2+/MYC+; double-expressor and double-hit lymphomas (DEL and DHL) had high stage (III, IV), more extra-nodal involvement, (P value <0.001) and intermediate to high International Prognostic Index (IPI) risk profile (P-value <0.001). The median overall survival was 14 months and 6 months for DEL and DHL, respectively. While all patients with DHL died during the follow-up period, the median PFS were only 2 months for DEL. There was a statistically significant correlation between mRNA of MYC and BCL2 with their protein expression (p<0.001).Conclusion:Our results confirmed the unique characters and poor outcome associated with DEL and DHL mandated the need for more intense therapy and not the standard protocol. Moreover, the significant correlation between protein overexpression and gene rearrangement may open the door for the possibility to use IHC instead of RT-PCR in developing countries.

Background: In terminal cancer patients (TCPs), one of the most important things is to define the survival to help the main responsible physicians, patients, and main caregivers make decisions, set goals, and work across the end-of-life strategies. Patients and Methods: We retrospectively reviewed the medical files of TCPs, who died during September 2011 and December 2017, to recognize the correlation between prognostic nutritional indices (PNIs) and survival in those subtypes of patients. The receiver operating characteristic (ROC) curve was used to identify the cutoff value of PNI. Results: A total of 858 TCPs were eligible and included, the median age was 62 years (range: 18–107). The most common primary cancer sites were colorectal cancer in 151 patients (17.6%), hepatobiliary in 129 (15%), lung cancer in 115 (13.4%), breast cancer in 114 (13.3%), and genitourinary in 80 (9.3%). The mean value of PNI for all cancer types was 32.9 ± 6.7. The values showed different levels across cancer types. For patients who lived >2 weeks, PNI was 36.7 compared with that who died within 2 weeks was 29.3, which was a statistically significant ( P < 0.001). By the ROC curve, the cutoff value of PNI was 32.3 and area under the curve was 0.888. The sensitivity, specificity, positive predictive value, and negative predictive value were 91.28% (95% confidence interval [CI]: 88.2–93.8), 71.09% (95% CI: 66.5–75.4), 76.5% (95% CI: 73.7–79.2), and 88.8% (95% CI: 85.3–91.5), respectively. Conclusion: The PNI is an easy and an applicable biomarker to estimate life expectancy in TCPs.
