Rose geranium in sesame oil nasal spray to improve nasal vestibulitis symptoms: a randomized controlled trial.

PURPOSE: The purpose of this phase III randomized double-blinded controlled trial was to investigate the efficacy of a rose geranium in sesame oil (RG) nasal spray compared with an isotonic saline (IS) nasal spray for alleviating nasal vestibulitis symptoms among patients undergoing chemotherapy. METHODS: Patients undergoing active chemotherapy who reported associated nasal symptoms were randomized 1:1 to receive RG or IS, administered twice daily for 2 weeks. Consenting participants completed nasal symptom questionnaires at baseline and then weekly while on treatment. The proportion of patients experiencing improvements in their nasal symptoms 2 weeks after initiating the nasal spray, using a six-point global impression of change score, was estimated within and between each randomized arm, and compared between arms, using Fisher's exact test. The estimated odds ratio was determined (95% confidence interval). RESULTS: One hundred and six patients consented to this study; 43 participants in the RG arm and 41 in the IS arm were evaluable for the primary endpoint. Participants had a mean age of 57.8 years (SD 13.9). Demographic characteristics and baseline nasal symptoms were similar between arms. Of the evaluable participants who received RG, 67.4% reported improved nasal symptoms, compared with 36.6% of the participants who received IS (P = 0.009). Adverse events were sparse and did not differ between arms. CONCLUSION: Rose geranium in sesame oil significantly improves nasal vestibulitis symptoms among patients undergoing chemotherapy.

Natural history of nasal vestibulitis associated with paclitaxel, docetaxel, and other chemotherapy agents: a Minnesota Cancer Clinical Trials Network (MNCCTN) study.

PURPOSE: To describe the natural history of nasal vestibulitis in patients receiving taxane chemotherapy, including incidence, severity, and associated symptoms. METHODS: Eligible patients with minimal or no baseline nasal symptoms were enrolled in this natural history study at initiation of a new chemotherapy regimen. Patients completed nasal symptom logs each time they received a chemotherapy dose. This manuscript reports upon the patients who received paclitaxel, docetaxel, or non-taxane non-bevacizumab chemotherapy. The proportions of patients within each cohort reporting any treatment-emergent nasal symptoms were estimated, with corresponding exact 95% confidence intervals. A cumulative incidence function was estimated within the chemotherapy cohorts to calculate the cumulative incidence rate of treatment-emergent nasal vestibulitis, treating death and disease progression as competing risks. RESULTS: Of the 81 evaluable patients, nasal symptoms were reported by 76.5% (58.8%, 89.3%) receiving paclitaxel, 54.2% (32.8%, 74.5%) receiving docetaxel, and 47.8% (26.8%, 69.4%) receiving non-taxane and non-bevacizumab chemotherapy. Of the three pairwise chemotherapy group comparisons, both the tests comparing the cumulative incidence function between the paclitaxel and non-taxane non-bevacizumab chemotherapy cohorts and between the paclitaxel and docetaxel cohorts achieved statistical significance at the 5% level with a higher incidence of treatment-emergent nasal vestibulitis in the paclitaxel cohort in both comparisons (P = 0.026 and P = 0.035, respectively). These significant differences were retained in the cumulative incidence function regression analysis controlling for age, smoking history, allergies, and asthma. Most patients in the paclitaxel cohort reported nasal symptoms as moderate or severe (56%). CONCLUSION: Patients receiving paclitaxel chemotherapy experience a high incidence of nasal symptoms.

Paraproteins of familial MGUS/multiple myeloma target family-typical antigens: hyperphosphorylation of autoantigens is a consistent finding in familial and sporadic MGUS/MM.

Paratarg-7 (P-7) is a frequent paraprotein target in monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma (MM), and Waldenström macroglobulinemia. Patients with P-7-specific paraproteins carry a hyperphosphorylated paratarg-7 (pP-7). Because pP-7 carrier state is dominantly inherited, we determined the paraprotein targets in 4 families with familial MGUS/MM. No antigenic target was identified for the paraproteins from 2 members of one family. Paraproteins from affected members of 2 other families targeted P-7, and paraproteins from 4 affected members of a fourth family targeted P-8, which is encoded by the ATG13 gene. P-8 was hyperphosphorylated in the affected family members (pP-8) and pP-8 carrier state is inherited in a dominant fashion. Six additional autoantigenic nonfamilial paraprotein targets were also hyperphosphorylated in the respective patients compared with normal controls. We conclude that paraproteins of affected members with familial MGUS/MM share family-typical hyperphosphorylated antigens and hyperphosphorylation of paraprotein targets might be a general mechanism underlying the pathogenesis of MGUS/MM.

Incidence of Brain Metastasis as First Event in Patients with Esophageal Carcinoma: a Report from Three Prospective Alliance Clinical Trials.

PURPOSE: Historically, reported incidence of brain metastasis secondary to esophageal carcinoma is low. We sought to determine the incidence of brain metastasis in a contemporary cohort of patients with carcinoma of the esophagus. METHODS: Data from patients with localized esophageal carcinoma prospectively enrolled on three curative intent Alliance treatment trials (N0044, N0342, N044E) were reviewed including time to diagnosis of first progression event (brain versus other site) and overall survival. RESULTS: Eighty-five patients comprised the cohort of which 85% were male and 86% had adenocarcinoma primary tumor histology. Thirty-nine of the 85 patients had documented progression to any site, and of those, brain metastasis occurred as the first event in 15% (6 of 39). Adenocarcinoma was the primary histology in all 6 patients and tumor grade was high (3 or 4) in 5 of the 6 patients (one not documented). Median time to brain metastasis (9.6 months) versus non-brain metastasis (12.4 months) and median survival after first progression (5.4 months versus 8.1 months, respectively) were not statistically different. CONCLUSION: In this prospective cohort of patients with esophageal carcinoma, those with high-grade adenocarcinoma appear to have a higher incidence of brain metastasis than historically reported. The pattern of brain metastases corroborates recent findings in terms of incidence, predominance of adenocarcinoma primary tumor histology, timing after diagnosis, and overall survival. Further study to confirm these findings, as well as the value of baseline, restaging and follow-up cranial imaging for brain metastasis is recommended.

A five arm natural history study of nasal vestibulitis.

INTRODUCTION: Nasal symptoms are frequently reported by patients undergoing chemotherapy. METHODS: Eligible patients planning to receive paclitaxel, docetaxel, nab-paclitaxel, bevacizumab without a concomitant taxane, or "other" (non-taxane, non-bevacizumab) chemotherapy regimens were invited to participate in this prospective study. Patients reported nasal symptoms prior to each dose of chemotherapy. RESULTS: The percentage of patients (95% CI) who reported nasal symptoms was the same for patients who received bevacizumab or nab-paclitaxel, 82.6% (61.2%, 95.1%). There were no significant differences among the proportions of patients experiencing nasal symptoms within the paclitaxel, nab-paclitaxel, and bevacizumab cohorts. Patients in the nab-paclitaxel cohort were more likely to experience symptoms than those in the non-taxane non-bevacizumab cohort or docetaxel cohort (p = 0.001, p = 0.001). Patients in the bevacizumab cohort were more likely to experience nasal symptoms than those in the non-taxane non-bevacizumab cohort (p = 0.03). CONCLUSION: Nasal vestibulitis symptoms are common in patients receiving chemotherapy, especially those receiving paclitaxel, docetaxel, and bevacizumab. Further investigations into treatments of this symptom complex are warranted.

The putative progenitor had progeny with two female partners. The progeny had prostate cancer, multiple myeloma, and MGUS.

Familial multiple myeloma.

In this issue of Blood, there are 2 reports on the increased risk of plasma cell disorders in the first-degree relatives of patients with multiple myeloma or MGUS.

Thrombotic Microangiopathy Care Pathway: A Consensus Statement for the Mayo Clinic Complement Alternative Pathway-Thrombotic Microangiopathy (CAP-TMA) Disease-Oriented Group.

Thrombotic microangiopathies (TMAs) comprise a heterogeneous set of conditions linked by a common histopathologic finding of endothelial damage resulting in microvascular thromboses and potentially serious complications. The typical clinical presentation is microangiopathic hemolytic anemia accompanied by thrombocytopenia with varying degrees of organ ischemia. The differential diagnoses are generally broad, while the workup is frequently complex and can be confusing. This statement represents the joint recommendations from a multidisciplinary team of Mayo Clinic physicians specializing in the management of TMA. It comprises a series of evidence- and consensus-based clinical pathways developed to allow a uniform approach to the spectrum of care including when to suspect TMA, what differential diagnoses to consider, which diagnostic tests to order, and how to provide initial empiric therapy, as well as some guidance on subsequent management.

Pooled analysis of fluorouracil-based adjuvant therapy for stage II and III colon cancer: who benefits and by how much?

PURPOSE: Although it is well-established that fluorouracil- (FU-) based adjuvant therapy improves survival for patients with resected high-risk colon cancer, the magnitude of adjuvant therapy benefit across specific subgroups and for individual patients has been uncertain. PATIENTS AND METHODS: Using a pooled data set of 3,302 patients with stage II and III colon cancer from seven randomized trials comparing FU + leucovorin or FU + levamisole to surgery alone, we performed an analysis based on a Cox proportional hazards regression model. Treatment, age, sex, tumor location, T stage, nodal status, and grade were tested for both prognostic and predictive significance. Model derived estimates of 5-year disease-free survival and overall survival (OS) for surgery alone and surgery plus FU-based therapy were calculated for a range of patient subsets. RESULTS: Nodal status, T stage, and grade were the only prognostic factors independently significant for both disease-free survival and OS. Age was significant only for OS. In a multivariate analysis, adjuvant therapy showed a beneficial treatment effect across all subsets. Treatment benefits were consistent across sex, location, age, T-stage, and grade. A significant stage by treatment interaction was present, with treatment benefiting stage III patients to a greater degree than stage II patients. CONCLUSION: Patients with high-risk resected colon cancer obtain benefit from FU-based therapy across subsets of age, sex, location, T stage, nodal status, and grade. Model estimates of survival stratified by T stage, nodal status, grade, and age are available at http://www.mayoclinic.com/calcs. This information may improve patients' and physicians' understanding of the potential benefits of adjuvant therapy.

Safety of thrice-daily hyperfractionated radiation and BCNU for high-grade gliomas.

PURPOSE: To investigate the safety of thrice-daily hyperfractionated radiotherapy (RT) given in conjunction with BCNU (carmustine) in high-grade gliomas. METHODS AND MATERIALS: Patients >18 years old with newly diagnosed high-grade gliomas were eligible. The dose of radiation was 5040 cGy, with a 1440-cGy boost in 180 cGy fractions delivered thrice daily in two 6-day periods with a 2-week interval. BCNU (200 mg/m(2)) was administered on the first day of radiation, then every 7 weeks for 1 year and every 10 weeks for another year. RESULTS: Eighteen patients were enrolled. The mean age was 49.6 years. Sixteen patients had astrocytomas (Grade 3 or 4 in 5 and 11 patients, respectively) and 2 had oligoastrocytomas (Grade 3 and 4 in 1 patient each). One underwent total resection, 9 subtotal resection, and 8 biopsy only. Thirteen patients had stable disease, 4 regression, and 1 progression. The median time to progression was 37.8 weeks. The median overall survival was 44.4 weeks. Nine patients had neurologic toxicities, including 2 deaths at 69 and 139 weeks. CONCLUSION: This regimen is unacceptably toxic. Factors that could have contributed to the toxicity may include the total radiation dose, thrice-daily hyperfractionation, and the concurrent use of i.v. BCNU.

Determination of potential adjuvant systemic therapy benefits for patients with resected cutaneous melanomas.

OBJECTIVE: To facilitate both better physician understanding of prognostic information (baseline and with adjuvant interferon) for individual patients who present with resectable melanomas and more informed patient decisions about whether they should receive adjuvant high-dose interferon therapy after resection of primary melanomas. PATIENTS AND METHODS: Baseline survival estimates were derived from a surgical database composed of 17,600 patients with complete clinical, pathologic, and follow-up data. Potential survival benefits ascribed to adjuvant interferon were obtained from results of a meta-analysis of Eastern Cooperative Oncology Group studies, which provided evidence for a uniform relative benefit of high-dose interferon across different baseline risk groups. A mathematical formula was then applied to these data to allow for individual prognostic information. RESULTS: The 5-year survival benefits in patients who received high-dose interferon after surgery, using the assumptions of the provided prognoses and interferon survival improvements, ranged up to 13%. CONCLUSIONS: These data should allow for a better understanding of baseline prognosis in individual patients and a better understanding of the potential benefits of adjuvant interferon. They should also help patients make more informed decisions regarding their treatment options.

Analysis of the human herpesvirus 8 (HHV-8) genome and HHV-8 vIL-6 expression in archival cases of castleman disease at low risk for HIV infection.

Lymph nodes from 44 patients with Castleman disease (CD) without risk factors for HIV infection were analyzed with polymerase chain reaction (PCR), in situ hybridization (ISH), and immunohistochemical analysis for human herpesvirus 8 (HHV-8) and viral interleukin-6 (vIL-6). PCR detected HHV-8 genome in 2 of 4 cases; ISH detected it in 9 of 16 cases. HHV-8 vIL-6 peptides were detected in 2 of 44 cases. vIL-6- and ISH-positive cells were found in large transformed and small lymphocytes of the follicular mantle, respectively. Of 9 cases of plasma cell (PC) CD that demonstrated HHV-8 genome by PCR or ISH, 1 expressed vIL-6. Clonal populations of PCs in CD by immunohistochemical analysis or immunoelectrophoresis of serum and urine were associated with neuropathy. HHV-8 vIL-6 detection was associated with poor survival and lack of HHV-8 IL-6, with low risk for subsequent lymphoma. Although HHV-8 genome was detected in a considerable number of patients with PC CD, vIL-6 expression was infrequent. Expression of HHV-8 vIL-6 in CD may indicate poor prognosis in patients at risk for lymphoma who may prospectively require more aggressive treatment. The lack of vIL-6 expression in CD with HHV-8 genome suggests that human IL-6 rather than vIL-6 may be the principal pathogenic cytokine.

Adjuvant chemotherapy for resected stage II and III colon cancer: comparison of two widely used prognostic calculators.

Two Web-based prognostic calculators (Adjuvant! and Numeracy) are widely used to individualize decisions regarding adjuvant therapy among patients with resected stage II and III colon cancer. However, these tools have not been directly compared. Hypothetical scenarios were formulated for the Numeracy calculator based on all potential combinations of age, lymph nodes status, tumor stage, and grade of tumor. These were then applied to three postsurgical therapy choices: observation, 5-fluorouracil (5-FU), or FOLFOX (5-FU, leucovorin, and oxaliplatin chemotherapy) to obtain the predicted 5-year disease-free survival (DFS) and overall survival (OS). Wilcoxon signed rank tests were used to compare the numerical predictions between the Adjuvant! and Numeracy calculators for each combination. A total of 192 hypothetical patient scenarios were obtained. For these patients, DFS and OS predictions from Adjuvant! were statistically significantly different than Numeracy (P <.05), except for four of 144 categories. While the estimated benefit in DFS and OS for 5-FU compared to surgery obtained from Adjuvant! and Numeracy were similar, the benefit in DFS and OS for FOLFOX over 5-FU, obtained from the Adjuvant! tool was slightly lower than that estimated from Numeracy. Among patients with resected stage II and III colon cancer, the DFS and OS estimates obtained from Numeracy and Adjuvant!, regarding the benefit of 5-FU over surgery, are similar, but the benefits of FOLFOX over 5-FU differ. Validation studies are needed to clarify the discrepancy and to assess the accuracy of these tools for predicting actual patient outcomes.

Initial report of a family registry of multiple myeloma.

About 20,000 Americans are diagnosed with multiple myeloma (MM) each year, and more than 10,000 die of MM in the United States annually. The etiology of MM remains unknown, although genetic and environmental factors have been implicated. Patients (n = 68) from the Myeloma Institute for Research and Therapy at the University of Arkansas for Medical Sciences and their family members with MM or a related malignancy were interviewed for environmental factors associated with MM and for family history data to complete pedigrees. In collaboration with Dr Henry Lynch at Creighton University, pedigrees of at least 3 generations were analyzed. Eighteen families (27%) have a putative autosomal dominant mode of genetic transmission of MM. Furthermore, the pedigrees indicate that pancreatic cancer, malignant melanoma, breast cancer, and lymphoma may be part of a myeloma syndrome. Environmental factors associated with MM present in this patient population were being born and raised in a rural area, raising cattle or cotton, and exposure to pesticides, insecticides, or herbicides. This work will be part of the efforts to create an international consortium to study familial MM. Research in the area of molecular epidemiology is needed to discover the genetic and environmental determinants of this disease.

Genetic counseling for DAPK1 mutation in a chronic lymphocytic leukemia family.

Genetic counseling has become the clinical bedrock of hereditary cancer management. Countless advances in molecular genetics contributing to the identification of cancer-causing germline mutations have increased its importance. We report a unique genetic counseling experience involving a family with hereditary chronic lymphocytic leukemia and the cancer-causing mutation in the death-associated protein kinase 1 gene (DAPK1). This hereditary disorder currently lacks any preventive or curative interventions for mutation carriers. This family has been under our investigation for a decade, during which time genealogy, cancer of all anatomic sites, medical and pathology records, and, whenever possible, slides and tissue blocks were reviewed. Family attendance at three group-oriented family information service sessions provided intensive education about this disease. Blood and skin fibroblasts were obtained for molecular genetic studies of DNA leading to the discovery of the DAPK1 mutation in the family. Their intellectual and emotional reaction to its presence or absence in them was assessed. This family serves as a model for genetic counseling in disorders for which lifesaving intervention is not yet possible.
