Fever-range whole body thermotherapy combined with oxaliplatin: a curative regimen in a pre-clinical breast cancer model.

Abstract PURPOSE: Studies were conducted to test whether fever-range whole body thermal therapy would boost the efficacy of oxaliplatin chemotherapy without substantial toxicity. MATERIALS AND METHODS: The effect of mild heat (40 degrees C) on oxaliplatin cytotoxicity, cellular uptake, and platinum-DNA adduct formation was studied in vitro using the MTLn3 tumour cell line. In vivo oxaliplatin was administered at various doses and times before, during and after fever-range thermal therapy (6 h at 40 degrees C) to rats bearing an MTLn3 mammary adenocarcinoma. Tumour growth, survival, and toxicity were measured to determine treatment outcome. RESULTS: Heating halved the oxaliplatin IC-50 dose for MTLn3 cells. Cellular uptake of platinum and platinum adducts increased by 34% and 36%, respectively, with heat. In vivo, 50% of all rats given 10 mg/kg oxaliplatin 24 h before thermal therapy were completely immunologically cured, while a further 11% regressed their primary tumour but ultimately succumbed to metastases, and 17% experienced a limited response with increased survival. The curative response occurred only in a narrow range of doses, with most cures at 10 mg/kg. Thermochemotherapy-treated, but uncured, animals had delayed incidence and slowed growth of metastases. Anti-tumour efficacy was greatest, and toxicity was least, when oxaliplatin was administered 12 or 24 h before fever-range whole body thermal therapy. CONCLUSIONS: When properly dosed and scheduled, oxaliplatin thermochemotherapy achieved permanent eradication of all primary and metastatic tumours in 50% of animals, seemingly through an immune response. Successful clinical translation of this protocol would yield hitherto unseen cures and substantial improvement in quality of life. <dl class="ecxrprtid"><dt>PMID:</dt><dd>20707651</dd><dd> [PubMed - indexed for MEDLINE] </dd></dl> Interview with Dr. Bull on thermotherapy: Fever Kills Cancer -- In-Depth Doctor's Interview http://_.ivanhoe.com/channels/p_chan...?storyid=21590 Short article: http://www.ivanhoe.com/channels/p_ch...?storyid=21587 "We are using a temperature that you would get if you had a bad case of the flu," Joan Bull, M.D., an oncologist at Memorial Hermann-Texas Medical Center in Houston, Texas, told Ivanhoe.

Fever-range whole-body thermal therapy combined with cisplatin, gemcitabine, and daily interferon-alpha: a description of a phase I-II protocol. Bull JM, Scott GL, Strebel FR, Nagle VL, Oliver D, Redwine M, Rowe RW, Ahn CW, Koch SM. Source The Division of Oncology, The University of Texas Medical School at Houston, Houston, TX 77030, USA. joan.m.bull@uth.tmc.edu Abstract PURPOSE: The purpose of the Phase I component of this study was to find the maximally tolerated dose (MTD) of cisplatin administered within a regimen of fever-range whole body thermal therapy (FR-WB-TT), cisplatin, gemcitabine, and low-dose interferon-alpha (IFN-alpha). The Phase II component aimed to assess which cancer diagnoses responded to the regimen, the response rate, and response duration. MATERIALS AND METHODS: The protocol design derived from a schedule-optimized preclinical regimen. Drugs were administered together, and also with thermal therapy in a schedule that optimized the therapeutic index. Eligible patients were those with therapy-resistant, metastatic or advanced solid malignancies. Beginning at 40 mg/m(2), the cisplatin dose was escalated by 10 mg/m(2) to the maximally tolerated dose (MTD) in successive cohorts of 3 patients. A treatment cycle consisted of cisplatin on day one, followed by thermal therapy and simultaneous gemcitabine 36 hours later; then a second dose of gemcitabine one week later; and daily IFN- alpha. RESULTS: Thirty-seven patients were treated on protocol. The MTD of cisplatin in the thermochemotherapy regimen was established to be 60 mg/m(2). The dose limiting toxicities (DLT) were peripheral neuropathy and ototoxicity. Complete and partial responses combined were 43%. The therapy improved the quality of life of responding patients. CONCLUSION: The protocol was well tolerated and was associated with antitumor activity in patients with a variety of advanced metastatic solid tumors. Tumor response occurred with the thermochemotherapy treatment despite treating malignancies that had progressed on the same chemotherapy drugs administered as standard treatment. Notably, good responses were observed in patients with high-grade neuroendocrine and pancreas cancers. This regimen will be tested in a phase II study. <dl class="rprtid"><dt>PMID:</dt><dd>18608594</dd><dd> [PubMed - indexed for MEDLINE] </dd></dl> http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2362074/ <table cellpadding="0" cellspacing="0" width="100%"><tbody><tr style="vertical-align: top;"><td>Br J Cancer. 2005 February 14; 92(3): 421–425.

However, suggestive clues on cause or trigger are sparse and not substantiated by much experimental evidence. In this review, literature is surveyed and summarised and possible causes are discussed. At least in a larger fraction of cases a hefty feverish infection is linked with spontaneous regression in time and is investigated as putative trigger. Epidemiological and immunological evidence is put into perspective. An online forum to discuss the possible application of fever therapy in the future can be accessed at http://bioinfo.tg.fh-giessen.de/fever-and-cancer. Spontaneous regressions and remissions from cancer have been recognised since the diagnosis of cancer became a science. Rohdenburg, a medical director at Columbia University, wrote in 1918: ‘It can be definitely asserted that regressive changes varying from a temporary standstill to the complete disappearance of the tumour, whether it be of epithelial or connective tissue origin, may occur at any age period, in either sex, and irrespective of the location of the growth'. On the other hand, large fractions of clinicians over large fractions of the century disregarded the phenomenon or denied that its existence has been proven beyond doubt. Although even a quick glance into the literature must convince us that unexplained healings from cancer happen, it is a rare event and, most importantly, the phenomenon of spontaneous healing in cancer remains almost without clue. Here I survey literature on spontaneous regression and remission and try to align with contemporary immunology and epidemiology. ...... CONCLUSION A large fraction of spontaneous regressions and remissions described in the literature was preceded by a hefty feverish infection. The hypothesis that fever can have therapeutic value can be brought in line both with successful historical attempts to apply fever using bacterial extracts and with immunological evidence. Putative beneficial effects of fever should as well act preventive, and indeed epidemiological studies show that a personal history of feverish infections reduces the likelihood to develop cancer later. Immunological strategies to break cancer cell tolerance should be individualised rather than generic. Fever induction will necessarily induce an individual response, which even addresses the problem of antigenic drift in time. Today we should be able to induce and control fever much better than 100 years ago. 20th September 2010 Jordan baffled doctors when his leukaemia vanished, new evidence suggests a remarkable explanation... can a fever cure cancer?

Pathogen-associated molecular pattern in cancer immunotherapy. Hobohm U, Stanford JL, Grange JM. University of Applied Sciences, Bioinformatics, Wiesenstrasse 14, D-35390 Giessen, Germany. uwe.hobohm@tg.fh-giessen.de Observations from different research frontiers--epidemiological data, case studies on spontaneous regressions from cancer, clinical studies, tumor immunology--indicate that exposure by vaccination or infection to pathogen-associated molecular patterns (PAMP) can have beneficial effects on neoplastic diseases, both prophylactically and therapeutically. These effects have not yet been harnessed to their full extent for the prophylaxis and therapy of cancer. Here, we summarize clinical, epidemiological, and experimental data and discuss the role of PAMP in cancer therapy. PMID: 18540826 [PubMed - indexed for MEDLINE] |
Re: Fever therapy
This is really interesting given the LIFT idea. It appears that an infection/temp may 'wake up' the natural white cells to recognise cancer cells, an ability which they appear to have lost.
Many years ago I attended a lecture by a visiting American onc who speculated that people who developed cancer had immune systems that had gone 'soft' ie not challenged by infection due to cleanliness, antibiotics etc. He was ridiculed and discredited for this hypothesis. Somehow I feel he was on the right track!! Ellie |
