Background:There is a paucity of literature examining the impact of timing of surgery after neoadjuvant chemotherapy. Objective:This study aimed to analyze the impact of the time taken to initiate surgical treatment following completion of neoadjuvant chemotherapy on patients’ outcomes by evaluating their pathological response, overall survival (OS), and disease-free survival (DFS). Methods:This is a retrospective review of 611 patients diagnosed with stage II and III breast cancer that received neoadjuvant chemotherapy and surgery between January 2004 and December 2014. The data was collected from a prospectively gathered registry. The patients were stratified into three cohorts according to the time of surgery after neoadjuvant chemotherapy: <4 weeks, 4–7 weeks, or ≥8 weeks. Outcomes were assessed using Kaplan-Meier curves, and the variables were compared using log-rank statistics. Results:The 5-year OS rate was 89.6% and the 5-year DFS rate was 74%. OS and DFS were not significantly different when stratified according to timing of surgery; however, the trends of OS and DFS were poor when surgery was delayed for ≥8 weeks. Median OS and median DFS have not yet been reached. Of the 17% of patients that had surgery after ≥8 weeks, 12.9% had pathological complete response (pCR), while among those that received surgery 4–7 weeks and <4 weeks after neoadjuvant chemotherapy, 26% and 21% had pCR, respectively (p = 0.02). ER+/HER-2+ patients had a statistically significant decrease in pCR if surgery was performed after ≥8 weeks. Conclusion:Our patients showed improved pCR if surgery was performed within 8 weeks, especially for ER+/HER-2+ patients. All patients had better OS and DFS trends if surgery was performed between 4 and 7 weeks after neoadjuvant chemotherapy.

AL amyloidosis is caused by the excessive production of nonfunctional immunoglobulins, leading to the formation of amyloid fibrils that damage vital organs, especially the heart and kidneys. AL amyloidosis presents with non-specific symptoms such as fatigue, weight loss, numbness, pain, and nephrotic syndrome. Consequently, diagnosis is often delayed, and patients typically present with advanced disease at diagnosis. The Pavia renal staging model stratifies patients based on their likelihood of progressing to dialysis. Treatment with daratumumab plus cyclophosphamide, bortezomib, and dexamethasone (i.e., Dara-CyBorD) was effective in inducing renal response in the landmark phase III ANDROMEDA trial and reducing early mortality. However, determining the most appropriate treatment regimen for relapsed or refractory cases remains a challenge due to various patient- and disease-related factors. Encouragingly, t(11:14) may be a positive indicator of therapy responses to the anti-BCL2 therapy venetoclax. Moreover, it is increasingly possible—for the first time—to clear AL amyloid fibrils from peripheral organs by leveraging novel anti-fibril immunotherapeutic approaches, although these medications are still under investigation in clinical trials. Given these advancements, this review provides a comprehensive overview of the current strategies for diagnosing, staging, treating, and monitoring AL amyloidosis, emphasizing renal involvement.

Introduction: Human epidermal growth factor receptor 2 (HER-2) targeted therapy regimens can improve tumor response in HER-2-positive metastatic breast cancer (MBC), with overall survival benefits. Objective: We evaluated the efficacy of dual HER-2 blockade combined with chemotherapy for HER-2-positive MBC patients as a first-line therapy in our patient population. Patients and Methods: We identified 75 patients at King Faisal Specialist Hospital and Research Center that received trastuzumab, pertuzumab, and docetaxel as a first-line therapy in HER-2 positive MBC in 2013–2016. Results: Median age at diagnosis was 45 years; 54.7% were estrogen receptor (ER)-positive. 10% of patients presented with only bone metastasis. The median follow-up time was 36 months with an objective response rate of 74.7% (complete response [CR] 18.7%; partial response [PR] 56%). The 5-year progression-free survival (PFS) and overall survival (OS) were 21% and 71.9% respectively, with a median PFS of 36 months (95% confidence interval [CI] 23.6–48.4). The 5-year OS for ER-negative and ER-positive patients was 93.9% and 59.4% respectively (p = 0.189); 23 patients experienced grade 1/2 toxicity and 2 patients had grade 3/4 toxicity. In terms of OS and PFS, the site of metastasis did not make any significant difference. Conclusions: First line pertuzumab, trastuzumab, and docetaxel for HER-2-positive MBC patients was found to be an effective and safe therapy in the Saudi population. This finding was consistent with the results seen in the CLEOPATRA trials.

Background: Data on race-related differences in the clinical outcomes of Takotsubo syndrome are limited, particularly for Black patients. This study aimed to assess whether race and sex may have an additional impact on the inpatient mortality of patients with Takotsubo syndrome. Methods: A total of 4,628 patients from the United States' National Inpatient Sample from 2012 to 2016 were identified; propensity score analysis revealed a similar propensity score between Black patients (n = 2,314) and White patients (n = 2,314), which was used to balance observed covariates. Sex and age distributions were identical between the 2 groups. The groups were also similar in baseline characteristics, including cardiovascular risk factors. White patients were compared with Black patients on in-hospital outcomes and inpatient mortality. A logistic regression analysis was conducted to measure the difference in mortality based on race and sex. Results: Compared with White patients, Black patients had a higher percentage of in-hospital complications, including cerebrovascular accidents (4.9% vs 2.5%, P ≤ .01), acute kidney injury (25% vs 19%, P ≤ .01); longer lengths of stay (8 vs 7 days, P ≤ .01); and higher inpatient mortality (6.1% vs 4.5%, P < .01). When analysis was conducted with race and sex combined, inpatient mortality was higher among Black men than among White women (odds ratio, 2.7 [95% CI, 1.80-3.95]; P ≤ .01). Conclusion: This study showed that Black patients with Takotsubo syndrome have higher in-hospital complications and inpatient mortality rates. When race and sex were combined, inpatient mortality was significantly higher among Black men than among either White men and women or Black women.

Background: Familial clustering of lymphoid and/or hematological malignancies (FHM) provides an opportunity to study the responsible genes. The data is limited in patients with lymphoid and hematological malignancies. Methods: The lymphoma database was used to identify patients seen in our institution from 1998 to 2019 with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). We studied FHM by collecting detailed history of any malignancy in the family (FM). Results: Two hundred NLPHL patients were identified. Contacting was not possible in 30 patients due to no response to the phone calls (22) and death [1]. 170/200 patients were interviewed; represented 167 families (3 patients with a family member with NLPHL). These 170 patients provided information about 8225 family members. These 167 families had a total of 329 family members with 334 malignancies (including 167 NLPHL patients and 5 members with 2 malignancies each). Of these 167 patients, 77 (46.1%) had no FM while 90 (53.9%) patients had a positive FM; 162 family members with 167 malignancies. Among these 167 families, 31 families (18.6%) had members with FHM +/− solid cancers. These 31 families had 35 family members (25 males:10 females) with 16 lymphomas: diffuse large B cell lymphoma [2], follicular center cell lymphoma [3], chronic lymphocytic leukemia/small lymphocytic lymphoma [3], non-Hodgkin lymphoma [2], classical HL [2], and NLPHL [4]. Total of 8 leukemia: acute lymphoblastic leukemia [4], acute myeloid leukemia [3], and leukemia - no subtyping [5]. These 35 FHM members are 1st [6], 2nd (16), and 3rd [7] degree relatives of 31 NLPHL patients. There are 4 families with NLPHL in family members; all these 8 NLPHL patients are male and are alive. The median total number of 1st + 2nd +3rd degree members are 81. The decrease in the age of diagnosis from 1st generation to the 2nd generation (anticipation) was noted in 13/17 patients; 2nd generation median age at diagnosis was 29.7 years vs 1st generation age 53 years (developed malignancy 23.3 years earlier). Conclusion: FHM is frequent in NLPHL. This study provided us many important insights for planning future studies in terms of interviewing technique, time, and resource allocation and genetic testing.
