Mammalian target of rapamycin (mTOR) is a protein serine/threonine kinase that was initially identified as the cellular target of rapamycin. This kinase regulates cell growth, proliferation, motility and survival, as well as the gene transcription and protein synthesis that are activated in response to hormones, growth factors and nutrients. Results from preclinical studies have indicated that factors antagonizing the mTOR pathway exert an antitumor effect on lung cancer. Furthermore, primary clinical trials of mTOR inhibitors have demonstrated that the inhibitors may be effective against lung carcinoma. The present study explores the association between mTOR and lung carcinogenesis and describes the clinical trials of mTOR inhibitors. © 2014, Spandidos Publications. All rights reserved.

Outpatient daily intravenous infusions of interleukin-2 (IL-2) have been developed to maintain anticancer activity and decrease toxicity of this agent against kidney cancer. Lymphokine activated killer cell (LAK) numbers are increased with these IL-2 schedules. Famotidine may enhance the LAK activity by increasing IL-2 internalization by the IL-2 receptor on lymphocytes. Fifteen patients with metastatic clear cell kidney cancer received IL-2 18 million IU/M2 intravenously over 15-30 minutes preceded by famotidine 20 mg IV daily for 3 days for 6 consecutive weeks as outpatients. Cycles were repeated every 8 weeks. Patient characteristics were seven males/eight females, median age 59 (range: 28-70), median Eastern Cooperative Oncology Group (ECOG) performance status-1; common metastatic sites were lungs (14), lymph nodes (9), liver (4), bone (4), and pancreas (4). Prior systemic therapies were oral tyrosine kinase inhibitor (8), IL-2 (6), and mTor inhibitor (2). Most common toxicities were rigors, arthralgia/myalgia, nausea/emesis, fever, and hypotension. All episodes of hypotension were reversible with intravenous fluid. No patients required hospitalization due to toxicity. One complete response (7%) and four partial responses (26%) were seen (total response rate=33%; 95% confidence interval: 15%-59%). Responses occurred in the lungs, liver, lymph nodes, and bone. Outpatient intravenous IL-2 with famotidine has activity in metastatic clear cell kidney cancer. © Mary Ann Liebert, Inc.

Naturopathic oncology is a relatively new and emerging field capable of providing professional integrative or alternative services to cancer patients. Foundational research is critical to identify topics in the clinical and research development of naturopathic oncology for future growth of the field. Study design. This study implements a modified Delphi protocol to develop expert consensus regarding ethics, philosophy, and research development in naturopathic oncology. Methods. The modified protocol implements a nomination process to select a panel of 8 physicians and to assist in question formulation. The protocol includes an in-person discussion of 6 questions with multiple iterations to maintain the concept of the Delphi methodology as well as a postdiscussion consensus survey. Results. The protocol identified, ranked, and established consensus for numerous themes per question. Underlying key topics include integration with conventional medicine, evidence-based medicine, patient education, patient safety, and additional training requirements for naturopathic oncologists. Conclusions. The systematic nomination and questioning of a panel of experts provides a foundational and educational resource to assist in clarification of clinical ethics, philosophy, and research development in the emerging field of naturopathic oncology. © The Author(s) 2015.

Background: Immune thrombocytopenic purpura (ITP) is a rare acquired bleeding disorder with an estimated incidence of 1 in 10,000 people in the general population. The association of ITP with breast cancer is an even rarer entity with very limited reports in the English literature. Case Presentation: We report a case of a 51-year-old female with no significant past medical history who presented with sudden onset of malaise, syncope, gingival bleed and epistaxis. She was found to have severe thrombocytopenia (platelet count 6,000/μl) and anemia (hemoglobin 7.2 g/dl). Her workup led to the diagnosis of metastatic ductal breast cancer with extensive bone metastasis. Bone marrow biopsy demonstrated myelophthisis which was initially thought to be consistent with her presentation of thrombocytopenia and anemia. Therefore, the patient was started on hormonal therapy for the treatment of her metastatic breast cancer. After 3 months of therapy, she did not improve and developed severe mucosal bleeding. Her clinical presentation was suspicious for ITP and immune-mediated anemia, and hence she was started on steroids and intravenous immunoglobulin. The patient had a dramatic response to therapy with normalization of her platelet count and hemoglobin within 2 weeks. Conclusion: To our knowledge, this is the first reported case of metastatic breast cancer presenting with symptomatic ITP and anemia, and both symptoms are postulated to be immune-mediated. © 2015 S.

Background: Pegylated liposomal doxorubicin (PLD) has a unique pharmacokinetic profile and is widely used to treat a variety of malignancies, alone or in combination with other agents. Case Report: A 57-year-old female patient with metastatic breast cancer developed dural metastases to the brain and underwent craniotomy and whole-brain radiation. She continued to receive chemotherapy with carboplatin without any serious complications. Four months later, there was evidence of progression leading to the institution of PLD. During the first course of PLD, there was evidence of acute encephalopathy which resolved after 18 h with discontinuation of this agent. Interestingly, she did well when she was rechallenged with conventional doxorubicin in the following cycles. Conclusion: We hereby report, to the best of our knowledge, the first case of acute transient encephalopathy induced by PLD. We postulate that partial disruption of the blood-brain barrier may have been responsible for PLD-induced encephalopathy. © 2014 S. Karger AG, Basel.
