Pain relief may come at too high a price
October 19th 2009An analysis by researchers at the University of Michigan Comprehensive Cancer Center shows that costs vary widely for different treatment regimens and from one delivery method to another. Yet receiving more treatments and spending extra on more sophisticated technology may do little good, at least when it comes to pain relief.
Epigenetic mechanisms may drive CD20 negative transformation in B-cell lymphoma
October 19th 2009Resistance to rituximab (Rituxan) has emerged as a considerable problem as the drug has become widely used to treat B-cell lymphomas, such as non-Hodgkin’s lymphoma, follicular lymphoma, and diffuse large B-cell lymphoma. A recent study in Blood suggested that resistance to rituximab is related to downregulation of CD20 expression via epigenetic mechanisms.
Proton-beam therapy calls for unique skills
October 19th 2009The first proton-beam therapy center in Loma Linda, Calif., opened almost 20 years ago, and today six are operating in the U.S. Another center will open by the end of 2009 with several more planned in the next two years, including centers in continental Europe and the UK. A growing body of research affirms the efficacy of proton-beam therapy (see Table).
Ultrasound images bear prognostic gems for oncology
October 16th 2009Subtle clues to the better management of cancer patients may lie hidden in images otherwise used exclusively for diagnosis. German researchers at ECCO/ESMO 2009 have found that ultrasound images of lymph nodes may contain clues to whether and to what extent melanoma has begun to spread. The discovery raises the possibility that ultrasound might help oncologists predict a patient’s probable survival without the need for sentinel node biopsy (abstract O9303).
Adjuvant Rx yields minor benefit in less aggressive colon cancer
October 15th 2009Stage II colon cancer patients who are negative for microsatellite instability and lymphocytic infiltrate should not undergo adjuvant chemotherapy, according to surgeons at Oregon Health and Science University and Legacy Health System, both in Portland.
Low-risk tumors exhibit high proliferation index
October 15th 2009Pathologists at the Yale University School of Medicine in New Haven, Conn., studied the relationship between the Oncotype Dx recurrence score and the cell cycle-related antigen Ki-67 in 32 breast carcinomas and evaluated for a potential association.
Brachytherapy or Surgery? A Composite View
October 13th 2009The comparison of brachytherapy and surgery may be done on several levels. This review focuses the comparison on toxicity, the “soft” endpoints of biochemical relapse-free survival and clinical relapse-free survival, and the “hard” endpoint of prostate cancer–specific mortality.
Further Perspectives on Treating Localized Prostate Cancer
October 13th 2009Standard treatment options for prostate cancer patients include surveillance, surgery, external-beam radiotherapy, brachytherapy, the combination of external-beam and brachytherapy, and the combination of radiotheraputic modalities with hormonal therapy, for appropriately chosen patients.
Novel chemoRT regimen ups survival in pancreatic ca
September 29th 2009In patients with resected pancreatic cancer, adjuvant cisplatin, 5-FU, and interferon chemoradiation produces a median survival of 27 months, according to initial results of the ACOSOG Z05031 trial. However, nearly all patients experience grade 3 or 4 toxicities.
Quality of life deficits offset benefits of preoperative rectal radiation therapy
September 29th 2009Although preoperative radiotherapy has been shown to improve recurrence and mortality rates in patients with rectal cancer, a quality-of-life analysis by the same researchers suggests that male sexual dysfunction and fecal incontinence may be the trade-offs for those improved outcomes
CT distinguishes liver cancer mets from lung primary
September 28th 2009Researchers in Seoul, Korea, found early-phase contrast-enhanced CT useful for differentiating pulmonary metastases from hepatocellular carcinoma and primary lung cancer. They specifically measured the attenuations of pulmonary nodules on the CT scans.
Panitumumab plus FOLFIRI bests FOLFIRI alone as second-line colon ca Rx
September 28th 2009BERLIN-Panitumumab (Vectibix), in combination with FOLFIRI as second-line treatment, significantly improved progression-free survival compared to FOLFIRI alone in patients with KRAS wild-type metastatic colorectal cancer, according to study results that will be presented at ESMO 2009 (see Table). However median overall survival did not achieve statistical significance in the study arm.
Avastin shows active anti-tumor activity in brain cancer
September 24th 2009Bevacizumab (Avastin) alone or in combination with irinotecan, was well tolerated and active in recurrent glioblastoma, according to phase II trial results. The multicenter, open-label, noncomparative trial evaluated 167 patients randomly assigned to receive bevacizumab (10 mg/kg) alone or in combination with irinotecan (340 mg/m2 or 125 mg/m2), with or without concomitant enzyme-inducing antiepileptic drugs, respectively, once every two weeks.
Age dictates risk when neoadjuvant hormone therapy is added to prostate brachytherapy
September 22nd 2009The risks associated with neoadjuvant hormonal therapy may outweigh the benefits of its use in conjunction with brachytherapy in some older men with prostate cancer, according to research from the radiation oncology program at Boston’s Harvard Medical School.
Perverse financial incentives tip usage in favor of IV drugs
September 22nd 2009More than a decade has passed since the FDA approved the first pill to fight cancer. Designed to battle metastatic colorectal cancer, capecitabine (Xeloda) marked a significant change in chemotherapy, untethering some cancer patients from office-based intravenous drug infusions. Other such drugs have since been commercially released, including temozolomide (Temodar) and imatinib (Gleevec), but the reimbursement system in this country has failed to keep up.
Should high-dose chemo/transplant still be considered first-line therapy in myeloma?
September 22nd 2009With the availability of newer drugs for treating multiple myeloma, such as proteosome inhibitors and immunomodulatory drugs (IMiDs), outcomes and depth of response are steadily improving. These developments have led to a debate about whether high-dose chemotherapy and autologous stem cell transplant should still be considered first-line therapy or whether newer drug regimens should replace transplant.
NCCN adds swine flu to guide for cancer-related infections
September 21st 2009The NCCN Clinical Practice Guidelines in Oncology for the Prevention and Treatment of Cancer-Related Infections has been updated to include information about the effect that the H1N1 virus may have on the diagnosis and treatment of cancer treatment-related infections.
