Outcomes of COVID-19 in Patients With a History of Cancer and Comorbid Cardiovascular Disease.

BACKGROUND: Cancer and cardiovascular disease (CVD) are independently associated with adverse outcomes in patients with COVID-19. However, outcomes in patients with COVID-19 with both cancer and comorbid CVD are unknown. METHODS: This retrospective study included 2,476 patients who tested positive for SARS-CoV-2 at 4 Massachusetts hospitals between March 11 and May 21, 2020. Patients were stratified by a history of either cancer (n=195) or CVD (n=414) and subsequently by the presence of both cancer and CVD (n=82). We compared outcomes between patients with and without cancer and patients with both cancer and CVD compared with patients with either condition alone. The primary endpoint was COVID-19-associated severe disease, defined as a composite of the need for mechanical ventilation, shock, or death. Secondary endpoints included death, shock, need for mechanical ventilation, need for supplemental oxygen, arrhythmia, venous thromboembolism, encephalopathy, abnormal troponin level, and length of stay. RESULTS: Multivariable analysis identified cancer as an independent predictor of COVID-19-associated severe disease among all infected patients. Patients with cancer were more likely to develop COVID-19-associated severe disease than were those without cancer (hazard ratio [HR], 2.02; 95% CI, 1.53-2.68; P<.001). Furthermore, patients with both cancer and CVD had a higher likelihood of COVID-19-associated severe disease compared with those with either cancer (HR, 1.86; 95% CI, 1.11-3.10; P=.02) or CVD (HR, 1.79; 95% CI, 1.21-2.66; P=.004) alone. Patients died more frequently if they had both cancer and CVD compared with either cancer (35% vs 17%; P=.004) or CVD (35% vs 21%; P=.009) alone. Arrhythmias and encephalopathy were also more frequent in patients with both cancer and CVD compared with those with cancer alone. CONCLUSIONS: Patients with a history of both cancer and CVD are at significantly higher risk of experiencing COVID-19-associated adverse outcomes. Aggressive public health measures are needed to mitigate the risks of COVID-19 infection in this vulnerable patient population.

PPX and Concurrent Radiation for Newly Diagnosed Glioblastoma Without MGMT Methylation: A Randomized Phase II Study: BrUOG 244.

PURPOSE: Efficacy signals but substantial myelosuppression were demonstrated in a single arm phase II study of paclitaxel poliglumex (PPX) in combination with temozolomide (TMZ) and radiation therapy (RT) for first-line treatment of glioblastoma. The objective of this randomized phase II trial was to assess the efficacy and safety of single-agent PPX with RT (PPX/RT) versus TMZ with RT (TMZ/RT) for glioblastoma without O-methylguanine-DNA methyltransferase (MGMT) methylation. MATERIALS AND METHODS: Patients with glioblastoma with unmethylated MGMT without prior chemotherapy or RT were eligible. Patients were randomly assigned 2:1 to PPX, 50 mg/m/wk for 6 weeks, or standard TMZ, with concurrent 60.0 Gy RT. One month after completion of chemoradiation all patients received standard maintenance TMZ. The primary endpoint was progression-free survival (PFS). RESULTS: Of the 164 patients enrolled, 86 were MGMT unmethylated. Of these, 63 patients were randomized (42 to PPX/RT and 21 to TMZ/RT). Fifty-nine patients could be analyzed. The median PFS was 9 months in the PPX/RT group and 9.5 months in the TMZ/RT group (hazard ratio in the PPX/RT group, 1.10; 95% confidence interval, 0.79-2.08; P=0.75). Median overall survival was 16 versus 14.8 months for PPX/RT and TMZ/RT groups, respectively (hazard ratio, 1.44; 95% confidence interval, 0.75-2.77; P=0.27). In the PPX and TMZ groups 44% versus 22% of patients, respectively, experienced one or more grade 3 or higher toxicities during chemoradiation. CONCLUSIONS: PPX/RT did not improve PFS or overall survival. This study provides an effective trial design for screening RT sensitizers in glioblastoma.

Phase 2 and biomarker study of trebananib, an angiopoietin-blocking peptibody, with and without bevacizumab for patients with recurrent glioblastoma.

BACKGROUND: Angiopoietins contribute to tumor angiogenesis and may be upregulated as a compensatory factor after vascular endothelial growth factor (VEGF) blockade. The authors performed a phase 2 and biomarker study to evaluate trebananib, an angiopoietin 1 and angiopoietin 2 blocking peptibody, with and without bevacizumab in patients with recurrent glioblastoma. METHODS: Forty-eight patients who had bevacizumab-naive, recurrent glioblastoma were treated with trebananib (30 mg/kg weekly) as single agent (n = 11) or combined with bevacizumab (n = 37). The primary endpoint was 6-month progression-free survival rate as determined by investigator review. Circulating biomarker levels were assessed before and after study therapy. RESULTS: Trebananib was well tolerated as monotherapy and did not enhance bevacizumab-associated toxicity. Trebananib had no single-agent activity, and all treated patients exhibited progressive disease within 2 months. The 6-month progression-free survival rate for trebananib plus bevacizumab was 24.3% (95% confidence interval [CI], 12.1%-38.8%); whereas the median overall survival was 9.5 months (95% CI, 7.5-4.7 months), and the 12-month overall survival rate was 37.8% (95% CI, 22.6%-53.0%). Baseline and post-treatment changes in circulating vascular VEGF and interleukin-8 levels were correlated with survival among patients who received trebananib plus bevacizumab. CONCLUSIONS: Angiopoietin 1 and angiopoietin 2 inhibition with trebananib was ineffective as monotherapy and did not enhance the ability of VEGF blockade with bevacizumab to improve the outcomes of patients with recurrent glioblastoma.

Compliance and safety of a novel home exercise program for patients with high-grade brain tumors, a prospective observational study.

PURPOSE: The purpose of this study is to evaluate compliance with and safety of a novel independent home exercise program for patients with high-grade brain tumors. We designed this program around the preferences and individual capabilities of this population as well as the potential barriers to exercise in cancer patients. Demographics were collected to better understand those that persisted with exercise. METHODS: Subjects with high-grade brain tumor received one-time training that included watching an exercise video and live demonstration of resistance band exercises, a balance exercise, and recommendations for walking. Subjects were instructed to do the exercises every day for 1 month. Main outcome measures were percentage of subjects who exercised throughout the month, frequency of exercising, demographic factors, quality of life scores (assessed by FACT-BR), and self report of adverse events. RESULTS: Fourteen of the 15 (93%) subjects started the exercises during the course of the month. Nine of the fifteen (60%) continued the exercises throughout the month. Three additional subjects would have continued to exercise if formal or supervised rehabilitation had been offered. Among the subjects who continued the exercises regularly, higher frequency of exercising was significantly associated with living as married (p = 0.033), annual income >$50,000 (p = 0.047), scores of physical well-being (p = 0.047), and brain cancer specific well-being (p = 0.054) subscales. Among those who exercised frequently, there was also a trend towards increase in total FACT-BR scores (p = 0.059). The subjects who scored higher on the social well-being subscale of the FACT-BR at baseline self-reported a higher likelihood to continue the exercises after 1 month of participation in the study (p = 0.018). No adverse events were reported. CONCLUSIONS: Our small group of subjects with high-grade brain tumors demonstrated compliance with and safety of a novel independent strength and balance exercise program in the home setting. Higher frequency of exercising was associated with life quality parameters as well as marriage and income.

Multi-modality management of craniopharyngioma: a review of various treatments and their outcomes.

Craniopharyngioma is a rare tumor that is expected to occur in ∼400 patients/year in the United States. While surgical resection is considered to be the primary treatment when a patient presents with a craniopharyngioma, only 30% of such tumors present in locations that permit complete resection. Radiotherapy has been used as both primary and adjuvant therapy in the treatment of craniopharyngiomas for over 50 years. Modern radiotherapeutic techniques, via the use of CT-based treatment planning and MRI fusion, have permitted tighter treatment volumes that allow for better tumor control while limiting complications. Modern radiotherapeutic series have shown high control rates with lower doses than traditionally used in the two-dimensional treatment era. Intracavitary radiotherapy with radio-isotopes and stereotactic radiosurgery may have a role in the treatment of recurrent cystic and solid recurrences, respectively. Recently, due to the exclusive expression of the Beta-catenin clonal mutations and the exclusive expression of BRAF V600E clonal mutations in the overwhelming majority of adamantinomatous and papillary tumors respectively, it is felt that inhibitors of each pathway may play a role in the future treatment of these rare tumors.

Distinguishing grade I meningioma from higher grade meningiomas without biopsy.

BACKGROUND: Many meningiomas are identified by imaging and followed, with an assumption that they are WHO Grade I tumors. The purpose of our investigation is to find clinical or imaging predictors of WHO Grade II/III tumors to distinguish them from Grade I meningiomas. METHODS: Patients with a pathologic diagnosis of meningioma from 2002-2009 were included if they had pre-operative MRI studies and pathology for review. A Neuro-Pathologist reviewed and classified all tumors by WHO 2007. All Brain MRI imaging was reviewed by a Neuro-radiologist. Pathology and Radiology reviews were blinded from each other and clinical course. Recursive partitioning was used to create predictive models for identifying meningioma grades. RESULTS: Factors significantly correlating with a diagnosis of WHO Grade II-III tumors in univariate analysis: prior CVA (p = 0.005), CABG (p = 0.010), paresis (p = 0.008), vascularity index = 4/4: (p = 0.009), convexity vs other (p = 0.014), metabolic syndrome (p = 0.025), non-skull base (p = 0.041) and non-postmenopausal female (p = 0.045). Recursive partitioning analysis identified four categories: 1. prior CVA, 2. vascular index (vi) = 4 (no CVA), 3. premenopausal or male, vi < 4, no CVA. 4. Postmenopausal, vi < 4, no CVA with corresponding rates of 73, 54, 35 and 10% of being Grade II-III meningiomas. CONCLUSIONS: Meningioma patients with prior CVA and those grade 4/4 vascularity are the most likely to have WHO Grade II-III tumors while post-menopausal women without these features are the most likely to have Grade I meningiomas. Further study of the associations of clinical and imaging factors with grade and clinical behavior are needed to better predict behavior of these tumors without biopsy.

A Phase II Trial of Cetuximab, Gemcitabine, 5-Fluorouracil, and Radiation Therapy in Locally Advanced Nonmetastatic Pancreatic Adenocarcinoma.

BACKGROUND: Pancreatic cancer is the fourth leading cause of cancer deaths in the United States. A minority of patients present with localized disease and surgical resection still offers patients the only hope for long-term survival. Locally advanced pancreatic cancer is defined as surgically unresectable, but has no evidence of distant metastases. The purpose of this study is to evaluate the efficacy and safety of cetuximab in combination with gemcitabine and 5-FU along with radiation therapy in locally advanced non-resectable, pancreatic adenocarcinoma, using progression free survival as the primary end point. METHODS: This was a prospective, single arm, open label pilot phase II study to evaluate the anti-tumor activity of gemcitabine (200 mg/m(2) per week) and cetuximab (250 mg/m(2) per week after an initial 400 mg/m(2) loading dose) with continuous infusion 5-FU (800 mg/m(2) over 96 hours) and daily concurrent external beam radiation therapy (50.4 Gy total dose) for six weeks (cycle 1) in patients with non-metastatic, locally advanced pancreatic adenocarcinoma. Following neoadjuvant treatment, subjects were re-evaluated for response and surgical candidacy with restaging scans. After resection, or also if not resected; subjects received further therapy with four 28-day cycles (cycles 2-5) of weekly gemcitabine (1000 mg/m(2)) and cetuximab (250 mg/m(2)) on days 1, 8, and 15. RESULTS: Between 2006 and 2011, twenty-six patients were screened and eleven of them were enrolled in the study. Most common reasons for screen failures were having resectable disease, metastatic disease or co-morbidity. Ten patients were able to tolerate and complete cycle 1 of chemoradiotherapy. One patient stopped the study prematurely due to grade III diarrhea. All except this one patient received planned radiation therapy. The response evaluation after cycle 1 showed one Partial Response, eight Stable Disease and two Progressive Disease. Four patients subsequently underwent surgical resection of the tumor. All patients had R0 resections. There was one preoperative mortality due to multiple organ failure. Median progression free survival (PFS) for four resected patients was 9.0 months while for unresected patients median PFS was 7.1 months. Median overall survival (OS) for four resected patients was 47.4 months and for unresected patients median OS was 17.0 months. Most common adverse events were hematologic (27%). Only two patients developed grade 3 neutropenia. Most common treatment related non-hematologic adverse events were diarrhea (10 of 11), nausea (8 of 11) and skin rash (10 of 11 patients). Only 9.5% of all reported non-hematologic adverse events were grade 3 or higher. CONCLUSIONS: The combination of cetuximab, weekly gemcitabine and continuous infusion of 5-FU with radiotherapy was quite well tolerated with intriguing clinical benefit and survival results in carefully selected patients with locally advanced pancreatic adenocarcinoma. A trial with larger sample size will be necessary to confirm these results.

Overview of chronic myeloid leukemia patients in Pakistan in the pre-imatanib era.

OBJECTIVE: To study the patient characteristics of patients diagnosed with chronic myelogenous leukemia (CML) at a tertiary care cancer hospital in Pakistan. METHODS AND MATERIALS: A retrospective analysis was conducted on CML patients treated between 1996 and 2004 at Shaukat Khanum Memorial Cancer Hospital and Research Center. RESULTS: A total of 461 CML patient charts were reviewed. The mean and median ages at presentation were much younger than in the prior reports in the western literature with a quicker progression of disease. CONCLUSION: The advent of tyrosine kinase inhibitors will likely have more impact on the lifespan of CML patients in Pakistan when compared with patients in the western hemisphere due to younger age at diagnosis.

Renal involvement in non-Hodgkin's lymphoma: the Shaukat Khanum experience.

BACKGROUND: Primary lymphoma of genitourinary system is rare as these organs do not contain lymphoid tissue, however secondary involvement often occurs. The most commonly affected genitourinary organ is the kidney. METHODS: Medical records of 901 patients with documented NHL seen at Shaukat Khanum Memorial Cancer Hospital & Research Center during 1995-2003 were studied for the incidence, histopathological, clinical and radiological correlation of renal involvement in NHL. RESULTS: 19(2.1%) patients had renal involvement. Male to female ratio was 3.75:1. Histology was diffuse large cell lymphoma in 12(63%) patients. IPI was High, High intermediate and Low intermediate in 17(89.5%) patients. Radiologically, 5(26.5%) patients had the disease above the diaphragm, 2(10.5%) patients had disease below the diaphragm while 12(63%) had disease on both sides of the diaphragm. 11(58%) showed complete response, 1(5.5%) showed partial response while 7(36.8%) showed progressive disease. CONCLUSION: Majority of patients with renal involvement had low intermediate or higher IPI compatible with significant progression rate. The findings and disease behavior in our population is comparable to those quoted in English literature. Radiological tools have made it easier to monitor disease response and renal biopsy is seldom required.

Variables associated with recurrence in breast cancer patients-the Shaukat Khanum Memorial experience.

From a cohort of female breast cancer patients registered at the Shaukat Khanum Memorial Cancer Hospital and Research Center, in Lahore, Pakistan, during the time period extending from December 1994 to December 2002, 700 subjects who were followed up in time, were selected. Those who presented with benign tumors, carcinoma in situ, or metastases were excluded from the analyses. Age, tumor size, nodal status, menopause, estrogen receptor (ER), and progesterone receptor (PR) status, at the time of presentation, were determined. Tumors were classified according to the TNM classification (American Joint Commission on Cancer (AJCC)-sixth edition), and subsequently, grouped into T1/T2 and T3/T4. Lymph nodes were categorized as N0 (node-negative) and N1, N2, and N3 combined (node-positive). The odds ratio (OR) for developing recurrence in T3/T4 versus T1/T2 was determined to be 2.06 (95% confidence interval (CI) 1.39-3.05, p < 0.001); the OR for node-positive relative to node-negative was found to be 2.54 (95 % CI 1.61-4.0, p < 0.001). Furthermore, the association between the odds of developing recurrence in ER-positive compared to ER-negative was represented by an OR of 0.61, (95 % CI 0.40-0.94 (p= 0.02)). These findings are consistent with the observations that ER-positive, node-negative, and T1/T2 lesions have a decreased risk of recurrence. Also, ER-positive patients may have a better response to hormonal treatment than those who are ER-negative.
