Studies have shown that cancer requires two conditions for tumor progression: cancer cell proliferation and an environment permissive to and conditioned by malignancy. Chemotherapy aims to control the number and proliferation of cancer cells, but it does not effectively control the two best-known conditions of the tumor-permissive environment: neoangiogenesis and tolerogenic immunity. Many malignant diseases exhibit poor outcomes after treatment with chemotherapy. Therefore, we investigated the potential benefits of adding an induction regimen of antiangiogenesis and antitumor immunity to chemotherapy in poor outcome disease. In a prospective, randomized trial, we included patients with advanced, unresectable pancreatic adenocarcinomas, non-small cell lung cancer, or prostate cancer. Two groups of each primary condition were compared: group 1 (G1), n = 30, was treated with the standard chemotherapy and used as a control, and group 2 (G2), n = 30, was treated with chemotherapy plus an induction regimen of antiangiogenesis and antitumor immunity. This induction regimen included a low dose of metronomic cyclophosphamide, a high dose of Cox-2 inhibitor, granulocyte colony-stimulating factor, a sulfhydryl (SH) donor, and a hemoderivative that contained autologous tumor antigens released from patient tumors into the blood. After treatment, the G2 group demonstrated significantly longer survival, lower blood level of neoangiogenesis and immune-tolerance mediators, and higher blood levels of antiangiogenesis and antitumor immunity mediators compared with the G1 group. Toxicity and quality of life were not significantly different between the groups. In conclusion, in several advanced malignancies of different primary localizations, an increase in survival was observed by adding an induction regimen of antiangiogenesis and antitumor immunity to standard chemotherapy.

Previous studies have demonstrated that glial cells play an important role in the generation and maintenance of neuropathic pain. Activated glial cells produce numerous mediators such as proinflammatory cytokines that facilitate neuronal activity and synaptic plasticity. Similarly, bladder pain syndrome/interstitial cystitis shares many characteristics of neuropathic pain. However, related report on the involvement of spinal glia in bladder pain syndrome/interstitial cystitis-associated pathological pain and the underlying mechanisms are still lacking. The present study investigated spinal glial activation and underlying molecular mechanisms in a rat model of bladder pain syndrome/interstitial cystitis.

The duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581).

A 39-year-old man presented to the hospital in April 2011 with a 2-month history of tonsillitis, night sweats, fatigue, weight loss, shortness of breath on exertion and a dry cough. He was a non-smoker, previously fit and well with no regular medication. Examination of the respiratory, cardiovascular and gastrointestinal systems was normal; he appeared generally well. C reactive protein and erythrocyte sedimentation rate were raised. A CT of the thorax showed mediastinal thickening and mediastinal lymphadenopathy. Whole body (18)F-fluorodeoxyglucose positron emission tomography showed diffuse tracheobronchial activity. Tracheal and lymph node biopsies showed non-specific features. Lung function tests showed an obstructive picture. A diagnosis of relapsing polychondritis was made. Immunosuppressive treatment was started, initially with oral methotrexate and prednisolone, later progressing to intravenous methylprednisolone and intravenous cyclophosphamide. Repeat bronchoscopy showed improvement in inflammation; however, the patient's symptoms were not improved. The patient's symptoms and lung function currently remain stable on maintenance oral prednisolone.

Nongestational choriocarcinoma is very rare and carries a poor prognosis in female patients. In this report, the authors present a case of nongestational choriocarcinoma with brain metastasis in a female. A 58-year-old female with intermittent back pain was referred to a private hospital. On examination, a mediastinal tumor and a pancreatic tumor were detected. Endoscopic ultrasound-guided fine needle aspiration biopsy of the tumor was performed for histological evaluation. Pathological diagnosis was difficult because only a small amount of tissue was collected. Head MRI showed multiple metastatic tumors in the brain. The patient was diagnosed with primary mediastinal choriocarcinoma with brain metastasis. She was treated with one course of an etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine regimen, but her general condition gradually deteriorated, and she died on day 41. Nongestational choriocarcinoma is drug resistant, whereas gestational choriocarcinoma has better chemotherapeutic sensitivity.
Newly diagnosed patients with histologically proven Hodgkin lymphoma were staged according to the Ann Arbor classification and divided into favorable (stage I, stage IIA, and IIIA) and unfavorable (stage IIB, IIIB, and IV) groups. Subjects classified as group 1 (favorable) were treated with six 28-day cycles of chemotherapy (COPP/COPP ± ABV). Subjects classified as group 2 (unfavorable) were treated with eight 28-day cycles of COPP/ABV chemotherapy.

Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting.

The OR (95% credible interval) of inducing an sCr remission at 6 months was 1.70 (0.51, 6.87) for mycophenolate mofetil (MMF) versus cyclophosphamide (CYC); 2.16 (0.38, 13.36) for tacrolimus (Tac) versus CYC; and 1.25 (0.13, 10.51) for Tac versus MMF. For proteinuric remission the OR was 1.46 (0.81, 3.04) for MMF versus CYC; 1.96 (0.80, 5.11) for Tac versus CYC; and 1.34 (0.43, 3.90) for Tac versus MMF. The probability (95% credible interval) of inducing a creatinine remission at 6 months was Tac 56% (19%, 88%); MMF 51% (23%, 79%); and CYC 37% (28%, 47%). The probability of inducing a proteinuric remission was Tac 41% (23%, 63%); MMF 34% (23%, 50%); CYC 26% (20%, 32%); azathioprine 10% (1%, 55%); prednisone 11% (2%, 38%). None of the results were conclusive when examined in a sensitivity analysis.
Studies published in English between January 1, 1984 and October 31, 2014 that reported PML in adult SLE patients were included. Immunosuppression was defined as exposure to ≥1 immunosuppressant drug of interest at PML diagnosis: belimumab, rituximab, mycophenolate mofetil, azathioprine, cyclophosphamide, methotrexate and high-dose corticosteroids (>15 mg/day). Minimal immunosuppression was defined as low-dose corticosteroids (≤15 mg/day) and/or anti-malarials.

We report an adult T-cell leukemia-lymphoma (ATL) patient suffering from fatal reactivation of hepatitis B virus (HBV) infection after treatment with the anti-CC chemokine receptor 4 (CCR4) monoclonal antibody, mogamulizumab. HBV reactivation occurred without liver damage in this hepatitis B surface antigen (HBsAg) negative patient, who was seropositive for antibodies against the viral core and surface antigens at baseline, after two cycles of CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisolone) followed by six cycles of THP-COP regimen (cyclophosphamide, pirarubicin, vincristine and prednisolone). Unexpectedly, mogamulizumab monotherapy for relapsed CCR4 positive ATL induced sudden and fatal liver failure due to HBV reactivation, despite antiviral prophylaxis with entecavir. This clinical course may not only offer important suggestions to prevent critical HBV reactivation in HBsAg positive cancer patients who receive immune-enhancing drugs such as anti-CCR4 antibody, but also provide a clue to understanding the pathogenesis of HBV reactivation following systemic chemotherapy.

The urothelium is a frontline sensor of the lower urinary tract, sampling the bladder lumen and stimulating an immune response to infectious and noxious agents. Pattern recognition receptors (PRRs) recognize such agents and coordinate the innate response, often by forming inflammasomes that activate caspase-1 and the release of interleukin-1. We have shown the presence of one PRR (NLRP3) in the urothelia and its central role in the inflammatory response to cyclophosphamide. The purpose of this study was to (1) assess the likely range of the PPR response by assessing the repertoire present in the rat bladder and (2) determine the utility of the MYP3 rat urothelia cell line for in vitro studies by assessing its PPR repertoire and functional responsiveness.

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by acute thunderclap headache, evidence of vasoconstriction in conventional angiography or magnetic resonance angiography and reversibility of these phenomena within 12 weeks. Some triggering factors, for example drugs such as selective serotonin reuptake inhibitors, sumatriptan, tacrolimus, cyclophosphamide and cocaine, or states such as pregnancy, puerperium or migraine have been described. We describe the case of a 29-year-old woman with RCVS associated with fingolimod three months after childbirth. This case represents the first report of RCVS in fingolimod treatment.

Thirty-four subjects (68 cycles of AC) were enrolled. Mean (range) maximum nausea score in the first AC cycle was 58 (40-90). Thirty-three subjects (97 %) received the same AC doses in the second as in the third cycle. Mean (±standard error) maximum nausea scores in patients receiving ginger and placebo were 35.36 (±4.43) and 32.17 (±3.71), respectively. The difference in mean maximum nausea scores was 3 (95 % confidence interval, -3 to 9; P = 0.3). There were no significant differences between ginger and placebo in terms of vomiting incidence and severity, rescue medication use, chemotherapy compliance, and adverse events.

Of the 560 patients enrolled, 532 were included in the intention-to-treat analysis for response, and 485 in the primary analysis for response. The median age was 70 years. Although complete-remission rates were similar with R-FC and R-CHOP (40% and 34%, respectively; P=0.10), progressive disease was more frequent with R-FC (14%, vs. 5% with R-CHOP). Overall survival was significantly shorter with R-FC than with R-CHOP (4-year survival rate, 47% vs. 62%; P=0.005), and more patients in the R-FC group died during the first remission (10% vs. 4%). Hematologic toxic effects occurred more frequently in the R-FC group than in the R-CHOP group, but the frequency of grade 3 or 4 infections was balanced (17% and 14%, respectively). In 274 of the 316 patients who were randomly assigned to maintenance therapy, rituximab reduced the risk of progression or death by 45% (in remission after 4 years, 58%, vs. 29% with interferon alfa; hazard ratio for progression or death, 0.55; 95% confidence interval, 0.36 to 0.87; P=0.01). Among patients who had a response to R-CHOP, maintenance therapy with rituximab significantly improved overall survival (4-year survival rate, 87%, vs. 63% with interferon alfa; P=0.005).

Cancer immune escape is frequently associated with the induction of an inappropriate immune response, i.e., a response that does not inhibit but perhaps even promotes the tumor. Indeed, increased frequencies of tumor-infiltrating regulatory T cells (Tregs) are associated with an impaired prognosis in several cancers. Thus, depletion of Tregs, e.g., by cyclophosphamide, was proposed as a means to boost immune responses to cancer. In the present issue of the Journal, Sevko et al., however, provide evidence that cyclophosphamide exerted the unexpected effect of induction of myeloid-derived suppressor cells.
