ABSTRACT

SARS-CoV-2 infection induces myocardiopathy in 19% of severe cases, with a mortality rate of up to 51%. The mainstay of treatment is supportive care, steroids, and tocilizumab (anti-IL-6). This is a case of a 43-year-old woman diagnosed with hormone-positive breast cancer with lung metastasis and pulmonary lymphangitis carcinomatosis (PLC). Her baseline cardiac function was within normal limits. She presented to the emergency department with respiratory distress. Chest CT showed multiple bilateral ground-glass opacities consistent with COVID-19 pneumonia and confirmed by COVID-19-PCR nasal swab. Her condition deteriorated, and she was urgently admitted to the intensive care unit with evidence of a cytokine storm. She was started on tocilizumab, dexamethasone, and meropenem. Echocardiogram (echo) showed a severely reduced ejection fraction with severe global hypokinesis. A second dose of tocilizumab was given, and the dexamethasone dose was increased. Fortunately, the patient had significant clinical and biochemical improvement and regained her normal cardiac function. In conclusion, dexamethasone and tocilizumab could be promising aids in treating cardiomyopathy secondary to SARS-CoV-2 infection.

ABSTRACT

BACKGROUND: Gastroenteropancreatic Neuroendocrine tumors (GEP-NET) are rare neoplasms with limited reported data from the Middle East. Our study aims to report the clinicopathological feature, treatment patterns, and survival outcomes of patients with GEP-NET from our part of the world. METHODS: Medical records of patients diagnosed with GEP-NET between January 2011 and December 2016 at a single center in Saudi Arabia were reviewed retrospectively, and complete clinicopathological and treatment data were collected. Patients' survival was estimated by the Kaplan-Meier method. RESULTS: A total of 72 patients were identified with a median age of 51 years (range 27-82) and male-to-female ratio of (1.1). The most common tumor location was the pancreas (29.1%), followed by small bowel (25%), stomach (12.5%), rectum (8.3%), colon (8.3%), and appendix (6.9%). Forty-one patients (57%) had well-differentiated grade (G)1, 21 (29%) had G2, and 4 (6%) had G3. In five patients, the pathology was neuroendocrine carcinoma and in one it could not be classified. 54.2% of the patients were metastatic at diagnosis. Forty-two patients underwent surgical resection as primary management while 26 underwent systemic therapy, three patients were put on active surveillance, and one was treated endoscopically with polypectomy. The 5-year overall survival and progression-free survivals were 77.2% and 49%, respectively, for the whole group. Patients with G1 and 2 disease, lower Ki-67 index, and surgically treated as primary management had significantly better survival outcomes. CONCLUSION: Our study suggests that the most common tumor locations are similar to western reported data. However, there seems to be a higher incidence of metastatic disease at presentation than in the rest of the world.

ABSTRACT

PURPOSE: Follow-up care of early breast cancer (EBC) patients usually includes routinely scheduled physical examinations. While ASCO guidelines recommend a physical exam every three to six months for the first three years, little evidence supports this schedule. We evaluated recurrence detection of patients transferred into a single centre survivorship program that follows ASCO recommendations. METHODS: Patients with EBC referred to the Wellness Beyond Cancer Program (WBCP) who had breast cancer recurrence between February 1, 2013, and January 1, 2019 were reviewed. Descriptive analyses were used to present patient and disease characteristics stratified by type of recurrence and mode of cancer detection. RESULTS: Of 206 recurrences, 135 were distant recurrences (65.5%), 41 were ipsilateral breast recurrences (19.9%), and 30 were contralateral breast primaries (14.6%). Distant recurrences were primarily detected via patient-reported symptoms (125/135, 92.6%). 53.7% (22/41) of ipsilateral breast recurrences were detected by patients and 41.5% (17/41) by routine imaging. Contralateral breast primaries were primarily detected by imaging 83.3% (25/30) and patient-reported symptoms 16.7% (5/30). Only 2/206 (1.14%) recurrences/new primaries were detected by healthcare providers at routinely scheduled follow-up visits. CONCLUSIONS: Despite following ASCO guidelines, healthcare providers rarely detect recurrences at routinely scheduled follow-up appointments. Our data suggests that approximately 35, 000 follow-up visits were required for healthcare providers to detect these 2 recurrences. While reduced in-person visits may affect other aspects of follow-up care (e.g. toxicity management), it appears unlikely, provided patients attend regular screening tests, that less frequent in-person follow-up is associated with worse breast cancer-related outcomes.

ABSTRACT

Outcomes for patients with high-grade glioma remain poor. Temozolomide (TMZ) is the only drug approved for first-line treatment of glioblastoma multiforme, the most aggressive form of glioma. Chronotherapy highlights the potential benefit of timed TMZ administration. This is based on pre-clinical studies of enhanced TMZ-induced glioma cytotoxicity dependent on circadian, oscillating expression of key genes involved in apoptosis, DNA damage repair, and cell-cycle mediated cell death. The current systematic review's primary aim was to evaluate the efficacy and toxicity of TMZ chronotherapy. A systemic review of literature following PRISMA guidelines looking at clinical outcomes on TMZ chronotherapy on gliomas was performed. The search in the English language included three databases (PubMed, EMBASE, and Cochrane) and five conferences from 1946 to April 2022. Two independent reviewers undertook screening, data extraction, and risk-of-bias assessment. A descriptive analysis was conducted due to limited data. Of the 269 articles screened, two unique studies were eligible and underwent abstraction for survival and toxicity findings. Both studies-one a retrospective cohort study (n = 166) and the other a prospective randomized feasibility study (n = 35)-were conducted by the same academic group and suggested a trend for improved overall survival, but possibly increased toxicity when TMZ was administered in the morning (vs. evening). There was limited evidence suggesting possible therapeutic value from administering TMZ in the morning, which may be consistent with the pre-clinical observations of the importance of the timing of TMZ administration in vitro. Larger, pragmatic, prospective randomized controlled trials are needed to ascertain the value of TMZ chronotherapy to provide optimized and equitable care for this population.

ABSTRACT

Small bowel adenocarcinoma (SBA) is an extremely rare cancer type. In the present study, the patient characteristics and clinical outcomes of patients diagnosed and treated for SBA at a single tertiary hospital were reported. All patients diagnosed and managed between 2007 and 2020 were reviewed. Regression analysis was used to assess variables associated with the metastatic stage at diagnosis. The Kaplan-Meier method was used to estimate survival and the log-rank test was used to determine factors associated with survival outcomes. Out of 137 cases of small bowel primary tumor, 43 consecutive patients with SBA were diagnosed with a median age of 53 years and the majority (76.7%) were males. The common initial presenting symptoms were abdominal pain (58.8%) and bowel obstruction (30.2%). The most common primary site was the duodenum (60.5%) and the majority (65.1%) were diagnosed with stage III/IV disease. Patients with a high neutrophil-lymphocyte ratio (NLR) (≥0.85) were more likely to be in the metastatic stage at diagnosis (P=0.01). The 3-year overall survival (OS) rates based on stage were 100% (I), 85% (II), 53% (III) and 33.9% (IV) (P=0.001). In addition to the stage, the Eastern Cooperative Oncology Group Performance Status (P<0.001), NLR (P<0.001), hypoalbuminemia (P=0.02) and chemotherapy in a metastatic setting (P=0.02) were prognostic factors for OS. In conclusion, NLR is a potential prognostic biomarker for a metastatic stage at diagnosis. Advanced stage, lower performance status score, low albumin level and high NLR are associated with short OS.

ABSTRACT

PURPOSE: Infertility is a critical late toxicity that impacts adolescent and young adult (AYA, ages 15-39 years) cancer survivors. International oncology societies recommend discussing fertility preservation (FP) for all AYA patients, regardless of stage or prognosis. We aim to understand Canadian medical oncologists' perceptions, attitudes, and knowledge toward FP and pregnancy in patients with cancer, including advanced stages and high risk for recurrence. METHODS: An anonymous electronic survey utilizing hypothetical scenarios was sent to medical oncologists in the province of Ontario, Canada. Descriptive statistics were used to summarize all data. Logistic regression models were constructed to identify factors that predicted FP discussions and referrals. RESULTS: The survey was received by 91 medical oncologists, and the response rate was 44%. Fifty-eight percent of respondents offer FP for all patients. Physicians are more likely to refer patients for FP before curative intent therapy than before palliative chemotherapy (95% vs. 39.5%, p < 0.001). Most respondents (86%) are comfortable discussing FP; however, only 31% self-reported feeling up-to-date on knowledge of current FP methods. Female physicians were more likely to report up-to-date knowledge and confidence discussing FP with patients. Forty percent of respondents identified that concerns about the welfare of the resulting offspring should not be a cause for denying patients assistance in reproduction. CONCLUSION: There is a significant difference in physician attitude toward offering FP based on the cancer stage. Increased awareness of standard of care guidelines and resources for difficult situations may improve the frequency of discussions about FP in motivated cancer patients.

ABSTRACT

PURPOSE: To review the successes and challenges of integrating systematic reviews (SRs) into the Rethinking Clinical Trials (REaCT) Program. METHODS: All REaCT program SRs were evaluated and descriptive summaries presented. RESULTS: Twenty-two SRs have been performed evaluating standard of care interventions for the management of: breast cancer (n = 15), all tumour sites (n = 4), breast and prostate cancers (n = 2), and prostate cancer (n = 1). The majority of SRs were related to supportive care (n = 14) and survivorship (n = 5) interventions and most (19/22, 86%) confirmed the existence of uncertainty relating to the clinical question addressed in the SR. Most SRs (15/22, 68%) provided specific recommendations for future studies and results were incorporated into peer-reviewed grant applications (n = 6) and clinical trial design (n = 12). In 12/22 of the SRs, the first author was a trainee. All SRs followed PRISMA guidelines. CONCLUSION: SRs are important for identifying and confirming clinical equipoise and designing trials. SRs provide an excellent opportunity for trainees to participate in research.

ABSTRACT

(1) Background: The management of gastrointestinal stromal tumors (GIST) has significantly evolved over the last two decades, with the introduction of tyrosine kinase inhibitors (TKI). We aim to report 10 years of experience of GIST management at a regional cancer center in Canada. (2) Methods: We retrospectively analyzed the records of 248 consecutive patients diagnosed with GIST between 2011 and 2021. We describe the clinical and pathological data, management, and outcome, including survival. (3) Results: The most common GIST sites were the stomach 63% (156), followed by the small bowel 29% (73). At diagnosis, 83% (206) of patients had localized disease (stage I-III). According to the modified National Institutes of Health consensus criteria (NIH) for GIST, around 45% (90) had intermediate or high-risk disease. Most patients, 86% (213), underwent curative surgical resection. Forty-nine patients received adjuvant imatinib, while forty-three patients had advanced disease and received at least one line of TKI. With a median follow-up of 47 months, the 5-year recurrence-free survival (RFS) rates for very low and low risk were 100% and 94%, respectively, while those for intermediate and high risk were 84% and 51%, respectively. The 5-year overall survival (OS) rates for very low and low risk were 100% and 94%, while intermediate, high risk, and advanced were 91%, 88%, and 65%, respectively. Using the Kaplan-Meier method, there were statistically significant differences in RFS and OS between NIH risk groups, p < 0.0005. In univariate analysis, ECOG, site, mitosis, secondary malignancy, and size were predictors for OS. High mitosis and large size (>5 cm) were associated with worse RFS. (4) Conclusions: Curative surgical resection remains the gold standard management of GIST. Our results are comparable to the reported literature. Further research is needed to explore histology's role in risk stratification and initiating adjuvant TKI.

ABSTRACT

Objectives: The objectives of the study was to describe cancer incidence in the Qassim region and compare it with the national incidence rate for all reported cancer sites over 15-years (2002-2016). Methods: A descriptive analysis was conducted using the Saudi Cancer Registry (SCR) data. The annual percentage change (APC) was computed using Joinpoint regression software. Results: The Qassim region contributed to 4.3% (n = 6118) of the total cancer burden in Saudi Arabia (SA). Cancer incidence increased throughout the study period; however, it did not reach statistical significance. The age-standardized rate (ASR) per 100,000 persons was higher in females 68.8 (95% CI: 60.2-77.3) than in males 57.0 (95% CI: 51.9-62.12), P < 0.001. Since 2011, colon and rectal cancers have replaced non-Hodgkin lymphoma (NHL) and liver cancer as the leading cancer types among men. In women, the breast is the leading cancer type, and since 2014, the colon and uterus replaced the thyroid and NHL as the second and fourth-most common cancers. ASR of nasopharyngeal, esophageal, and Hodgkin's lymphoma were significantly higher in Qassim as compared to SA. The following cancer types showed significant APC (2002-2016): in males; colon: APC = 7.3%, rectum: APC = 6.1%, bone: APC = 8.3%, and esophageal: APC -5.1%. In females; breast: APC = 6%, colon: APC = 7.2%, uterus: APC = 10.1%, kidney: APC = 15.3%, bone: APC = 8.1%, skin non-melanoma: APC = -8.1%, and myeloid leukemia: APC -14.2%. Conclusion: The significant changes in cancer incidence in Qassim warrant further studies on the risk factors and preventive measures.

ABSTRACT

Background Gastric cancer (GC) carries a poor survival outcome despite the availability of many therapeutic agents active in treatment. In this study, we aimed to evaluate the survival outcomes of metastatic GC treatment from a single center in Saudi Arabia and identify possible prognostic factors. Methodology Data on patients diagnosed with metastatic GC between December 2009 and November 2013 were collected and analyzed. Results During this period, 41 patients were diagnosed with a median age at diagnosis of 52 years, and 56.1% of patients were males. Only four (9.2%) patients had human epidermal growth factor receptor 2 overexpression. Overall, 83% were treated with oxaliplatin-based chemotherapy. The median progression-free survival (PFS) and overall survival (OS) were 4.1 and 15.4 months, respectively. Female sex was an independent prognostic factor for better PFS and OS. Normal lymphocyte count was associated with improved PFS. Conclusions Our study highlights poor outcomes in patients with metastatic GC and the need for further research in this field.

ABSTRACT

BACKGROUND: Brain metastasis in sarcomas is associated with a poor prognosis. Data regarding prognostic factors and clinical outcomes of surgical resection of brain metastasis from sarcomas are limited. The objective of this systematic review was to evaluate survival outcomes post-brain metastasectomy for patients with soft tissue and bone sarcomas. METHODS: A systematic review was conducted examining survival outcomes among adults and children with soft tissue and bone sarcoma undergoing brain metastasectomy, in the English language from inception up to May 31, 2021. Two reviewers independently evaluated and screened the literature, extracted the data, and graded the included studies. The body of evidence was evaluated and graded according to the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies and the Joanna Briggs Institute Critical Appraisal Checklist for Case Series. Results were synthesized using descriptive methods. A meta-analysis was not possible due to the low quality and heterogeneity of studies. RESULTS: Ten studies published between 1994 and 2020 were included: three were retrospective cohort studies and seven were case series. 507 patients were included, of whom 269 underwent brain metastasectomy. The median follow-up period ranged between 14 and 29 months. The median survival period after metastasectomy ranged from 7 to 25 months. The most common prognostic factors associated with survival included presenting performance status, age, number of brain metastases, presence of lung metastases, and peri-operative radiation therapy administration. DISCUSSION: Although the level of evidence is low, retrospective studies support that brain metastasectomy can be performed with reasonable post-operative survival in selected individuals.

ABSTRACT

This study assesses the survival in patients undergoing metastasectomy for leiomyosarcoma (LMS) and compares the outcomes by the site of metastasectomy. We conducted a systematic review and pooled survival analysis of patients undergoing metastasectomy for LMS. Survival was compared between sites of metastasectomy. We identified 23 studies including 573 patients undergoing metastasectomy for LMS. The pooled median survival was 59.6 months (95% CI 33.3 to 66.0). The pooled median survival was longest for lung metastasectomy (72.8 months 95% CI 63.0 to 82.5), followed by liver (34.8 months 95% CI 22.3 to 47.2), spine (14.1 months 95% CI 8.6 to 19.7), and brain (14 months 95% CI 6.7 to 21.3). Two studies compared the survival outcomes between patients who did, versus who did not undergo metastasectomy; both demonstrated a significantly improved survival with metastasectomy. We conclude that surgery is currently being utilized for LMS metastases to the lung, liver, spine, and brain with acceptable survival. Although low quality, comparative studies support a survival benefit with metastasectomy. In the absence of randomized studies, it is impossible to determine whether the survival benefit associated with metastasectomy is due to careful patient selection rather than a surgical advantage; limited data were included about patient selection.

ABSTRACT

BACKGROUND: Synovial sarcoma (SS) is a malignancy with high metastatic potential. The role of metastasectomy in SS is unclear, with limited data on prognostic factors and clinical outcomes. In this systematic review, we evaluate the survival outcomes post-metastasectomy for patients with SS. METHODS: A systematic review was undertaken following PRISMA guidelines. English studies reporting survival outcomes among adults and children with SS undergoing metastasectomy were evaluated. Databases were searched from inception to May 31, 2021, and included Medline, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov. Two reviewers independently undertook literature evaluation and screening, data extraction and grading of studies. Risk of bias assessments utilized the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies and the Joanna Briggs Institute Critical Appraisal Checklist for Case Series. Qualitative data was summarized in descriptive format, and survival outcome data were assessed for meta-analysis. RESULTS: Thirteen retrospective studies, published between 1993 and 2017, were included, four were cohort studies, and nine were case series. A total of 598 patients with SS were included, of whom 462 had metastatic pulmonary disease, and 309 underwent metastasectomy. The median ages of the study cohorts ranged from 14 to 51 years. The median survival period after metastasectomy ranged from 21 to 80 months. Patients who underwent metastasectomy had a lower risk of mortality compared to those who did not (pooled HR 0.26 95% CI 0.14-0.49). The most common prognostic factors associated with survival included a disease-free interval of greater than 12 months and complete resection of the metastases. DISCUSSION: Although the level of evidence is low, retrospective studies support a clinical advantage for metastasectomy in selected patients with metastatic SS. FUNDING: This was not a funded study. REGISTRATION: This protocol has been registered within the international prospective register of systematic reviews (PROSPERO) database (registration ID: CRD42019126906).

ABSTRACT

Background: Numerous chemotherapeutic agents have antitumor activity in recurrent/metastatic (R/M) nasopharyngeal cancer (NPC). Evidence of capecitabine's effectiveness as monotherapy is limited. Capecitabine tolerability in solid malignancies has ethnic and geographical variability. We investigated capecitabine's tolerability and identified potential prognostic factors for clinical outcomes in R/M NPC. Methods: A consecutive retrospective cohort of patients who received capecitabine as the first recurrence, second- or third-line monotherapy for metastatic NPC (2011-2019) was reviewed concerning patient characteristics, pathological features, treatment outcomes, and toxicity. Results: Fifty-one patients were eligible (median age at diagnosis: 42 [35.5-52.5] years). Most patients (78.4%) tolerated a standard oral dose of 1,250 mg/m2 capecitabine (2 weeks on/1 week off) in a 3-week cycle. The objective response rate was 49%, and the disease control rate was 66.7%, with a median response duration of 6.2 months. Hand-foot syndrome (HFS) was associated with a higher objective response rate (odds ratio, 5.1 [95% confidence interval: 1.18-21.98]; P = 0.02). The median follow-up duration was 17.8 (interquartile range: 7.8-30.4) months. The median (95% confidence interval) progression-free survival and overall survival were 6.6 (4.3-8.8) and 32.7 (25.9-39.5) months, respectively. HFS (P = 0.02), better performance status (P = 0.02), and absence of brain metastasis (P = 0.04) were associated with prolonged progression-free survival. Conclusion: Capecitabine monotherapy is effective and well-tolerated as a palliative treatment for R/M NPC. Despite the lower incidence of HFS in our patients, it remained a favorable prognostic factor for objective response and progression-free survival.

ABSTRACT

Purpose: Obesity is prevalent in Saudi Arabia and is associated with adverse clinical features and poor breast cancer (BC) outcomes. We determined the distribution of body mass index (BMI) and evaluated its association with disease characteristics and outcomes in women with non-metastatic BC. Patients and Methods: We conducted a retrospective analysis of a prospectively collected database of consecutive patients treated for non-metastatic BC between 2002 and 2014. Patients were categorized into the following groups: underweight/normal weight (BMI <25 kg/m2), overweight (BMI 25-29.9 kg/m2), and obese (BMI ≥30 kg/m2). Regression analysis was used to evaluate clinicopathological factors associated with BMI and clinical stage. Results: A total of 2212 patients were enrolled. The median age was 45 years (interquartile range [IQR], 39-52 years), and the median BMI was 30 kg/m2 (IQR, 26-34 kg/m2). Most patients were premenopausal (63.6%), nearly half of the patients had stage III disease, and 11.2% were screen-detected. The prevalence of obesity was 53.4%, with a significant difference between the peri/premenopausal (49.4%) and postmenopausal (61.7%) groups (p < 0.001). Obese patients were more likely to be aged >40 years, be postmenopausal, have a history of oral contraceptive pills, have advanced-stage disease, and have undergone radiation therapy, and were less likely to have human epithelial growth factor 2 (HER2)+ disease than non-obese patients. Premenopausal obese women had fewer hormone receptor-positive and more triple-negative cancers than postmenopausal obese women did. Obesity, non-screening-detected BC, and HER+ status were independent prognostic factors for advanced-stage presentation. Conclusion: The prevalence of obesity and its significant association with advanced BC justify the upscaling of screening services and instituting weight-reduction strategies.

ABSTRACT

BACKGROUND: The effect of longer-term use of bone-modifying agent (BMA) on symptomatic skeletal event (SSE) rates in patients with bone metastases remains unclear. This retrospective study of a cohort of patients in a randomized controlled trial evaluated SSEs in patients receiving BMAs at a single cancer center. METHODS: Data from patients with metastatic breast and castration-resistant prostate cancer (CRPC) were interrogated to evaluate the effects of longer-term use of BMAs on incidence, type, and risk factors for SSEs. RESULTS: Of 162 patients, 109 (67%) had breast cancer (BC) and 53 (33%) CRPC. Median age at diagnosis of bone metastases was 61.9 years (range 27.5-97.2) for BC patients and 72.1 (range 37.0-92.2) for CRPC patients. Median duration of BMA use was 2.3 years (range 0.1-9.9 years) for BC and 3.8 years (range 1.5-9.4) for CRPC patients. The initial BMAs in BC patients were pamidronate (46.8%), denosumab (31.2%), and zoledronate (22%). All CRPC patients received denosumab. During follow-up, 59% of BC and 75% of CRPC patients had at least one SSE. The number of patients experiencing ≥ 1 SSE per year was higher in the first year after bone metastasis diagnosis (63/162; 38.9%) compared with that in the second (26/149; 17.5%) and third years (30/123; 24.4%). Neither age, visceral disease, multiple bone metastases, nor biological markers for BC had a significant impact on time to first SSE. CONCLUSIONS: The risk for SSEs was greatest in the first year after diagnosis of bone metastasis. Studies evaluating de-escalation and even stopping of BMAs with longer-term use may therefore be warranted.

ABSTRACT

PURPOSE: BRCA gene mutations (BRCAm) have an impact on patients' characteristics and clinical outcomes of ovarian cancer (OC). The frequency and patterns of BRCAm vary among countries and ethnicities. There are limited data from Saudi Arabia (SA); thus, this study aims to determine the frequency, pattern, and impact on patient characteristics and outcomes of BRCAm OC compared to wild-type BRCA (BRCAw) in Saudi women. METHODS: This retrospective study evaluated women diagnosed with non-mucinous OC, fallopian tube, or peritoneal carcinoma who had BRCA status tested in an accredited lab between January 2016 and December 2017. The associations between various parameters and BRCAm were estimated using logistic regression. Statistical analysis performed with SPSS (Version 27). RESULT: Sixty-one women with a median age of 52 at diagnosis were analyzed. Germline BRCA mutations were found in 41% of cases (25/61). The most common deleterious germline BRCA1 mutation was c.1140dupG (39%). Most women (72%) had no family history of cancers and 82% had advanced stage. Regardless of BRCA mutations, an optimal overall response rate (ORR) to first-line treatment has been achieved although most cases relapsed (84%) and the majority were platinum-sensitive relapse (85%). Higher ORR to subsequent lines and better survival were obtained in women with BRCA-mutation. CONCLUSION: The prevalence of BRCAm of OC was higher in Saudi women compared to regional and most of the international figures. The better clinical outcomes of BRCAm women agreed with the reported evidence. Further studies on BRCA mutations of OC and genetic counseling are highly recommended. TRIAL REGISTRATION: Trial approved by the Institutional Review Board of King Faisal Specialist Hospital and Research Center (RAC # 2171137) and conducted at King Faisal Specialist Hospital and Research Center, PO Box 3354, Riyadh 11,211, Saudi Arabia.

ABSTRACT

PURPOSE: Pazopanib has been approved for treating soft tissue sarcomas (STS) after chemotherapy. We aimed to evaluate the prognostic factors, clinical outcomes, and tolerability of pazopanib in patients with STS. PATIENTS AND METHODS: Forty-five patients treated between June 2015 and August 2019 were reviewed. Clinical outcome was measured by assessing the disease control rate (DCR) using Response Evaluation Criteria in Solid Tumors (version 1.1). Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Adverse effects were assessed using the Common Terminology Criteria for Adverse Events (version 5.0). RESULTS: The median age of patients at diagnosis was 28 (interquartile range (IQR), 23-45) years. Pazopanib was used as the second-line treatment in 46.7% and the subsequent line in 53.3% of patients. The overall DCR was 55.6%, and at 8 and 12 weeks, it was 52.3% and 35.5%, respectively; the median duration of response was 7 (IQR: 2-18) months. Pazopanib-induced hypothyroidism was associated with DCR, with an odds ratio of 7 (95% confidence interval [95% CI: 1.7-27.5], p<0.01). The median PFS and OS were 4.1 (95% CI: 0.85-7.42) and 12.4 months (95% CI: 6.5-18.36), respectively. Hypothyroidism and response to pazopanib, better ECOG PS, histological subtypes desmoid tumor/aggressive fibromatosis (DT/AF), and alveolar soft part sarcoma (ASPS) were favorable prognostic factors for PFS. Hypothyroidism and response to pazopanib were significant favorable factors for OS. There was no statistical difference in the OS between patients using pazopanib as the second-line therapy and those using it as the subsequent-line therapy. CONCLUSION: Pazopanib is an effective treatment for STS. However, it showed variability in the clinical outcome in favor of ASPS and an outstanding response in the DT/AF subtype. Pazopanib-induced hypothyroidism is a good prognostic factor for disease control and is associated with prolonged PFS and OS.

ABSTRACT

PURPOSE: The correlation between the preoperative neutrophil-to-lymphocyte ratio (NLR) and Oncotype DX® (ODX) recurrence score (RS) has not yet been established. We aimed to investigate the association between NLR and ODX RS in patients with hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) early-stage breast cancer (BC). PATIENTS AND METHODS: This retrospective study included consecutive patients with HR+/HER2-, node-negative primary BC who underwent surgical tumor resection from 2011 to 2019. Receiver operating characteristic curve analysis was used to obtain an optimal NLR cutoff value. Logistic regression analyses were used to estimate associations between various parameters and ODX RS. Furthermore, the factors significantly associated with the ODX RS in multivariable analysis were incorporated in a separate model and estimated using logistic regression. RESULTS: A total of 160 patients were enrolled. The optimal preoperative NLR cutoff was 2.15. Multivariable analysis revealed that NLR and tumor grade (G1/G2 vs G3) were independent predictive factors of high RS cutoff (≥26). Moreover, including the two variables yielded a stronger association; patients with low NLR and low-grade tumors were unlikely to have high RS (≥26; odds ratio [OR] = 0.03, 95% confidence interval [CI]: 0.006-0.154; p < 0.001). Conversely, the presence of any of the following factors made patients unlikely to have low RS (<16; OR = 0.34, 95% CI: 0.16-0.73; p = 0.006): high NLR, high grade, or high Ki-67 levels (>20). CONCLUSION: NLR is a promising independent predictor of RS. Furthermore, in addition to tumor grade and Ki-67 level, they together are also a potential indicator of high and low RS. However, further studies are required to validate this hypothesis.

ABSTRACT

We present the case of a 26-year-old woman living at a high altitude diagnosed initially with nonfamilial and nonsecretory localized carotid body tumor managed with surgery, which developed into a recurrent metastatic tumor treated with cyclophosphamide, vincristine, and dacarbazine. The patient continued to progress and developed a left carotid artery thrombosis and worsening of her systemic symptoms. The patient was re-evaluated, and she decided on no further surgery or systemic therapy. DOTATATE positron emission tomography/computed tomography showed widespread somatostatin-avid disease involving the left carotid bulb mass, bilateral lung nodules, and liver metastases, with the largest in the right hepatic lobe measuring 8 × 7 cm. There were peripancreatic lymph nodes and scattered skeletal metastases. The patient sought a second opinion, on the basis of which she was prescribed pazopanib, to which she showed a dramatic clinical response after 1 month, followed by a durable response for 1 year. Tyrosine kinase inhibitors such as pazopanib are potentially useful in paraganglioma, with further studies needed to understand the role of vascular endothelial growth factor receptor-directed kinase inhibitors in this setting.
