Males can get HPV vaccine Gardasil thanks, in part, to Gulfport cancer survivor

Source: St. Petersburg Times Author: John Barry David Hastings' crusade to inoculate boys against a cancer-causing virus that afflicts women — but threatened him, too — has scored a victory. But it's not quite the one he has been fighting for in the past three years. A panel of the Centers for Disease Control and Prevention last week allowed a vaccine to be given to boys and young men that is already used to protect girls and young women from human papillomavirus, HPV, which causes cervical cancer. The panel's vote followed the Food and Drug Administration's recent okay of the vaccine for boys as a protection against genital warts. The vaccine, Gardasil, was approved only for females, ages 9 to 26, in 2006. But research has since linked HPV to many oral cancers in men. Hastings, who owns the Habana Cafe in Gulfport with his wife, Josefa, testified before the CDC's Advisory Committee on Immunization Practices. He told them how HPV was found in a deadly carcinoma in his throat in 2006. It took seven weeks of simultaneous chemotherapy and radiation at the H. Lee Moffitt Cancer Center in Tampa to arrest the cancer. Ever since, he has spread the message that HPV is a threat to men. He urged the CDC panel to recommend routine vaccinations for boys, as it already does for girls. Hastings and other proponents argued that only 17 percent of girls are completing the series of three doses needed for protection. "We rely on females [...]

Pinter opens up about private battle with cancer

Source: Fairfield Citizen Author: Morgan Thomas In the 31 years that Redding actress Colleen Zenk Pinter has played Barbara Ryan on As the World Turns, her character has been in a coma following an automobile accident, survived a gunshot wound, been burned to a crisp in an explosion and imprisoned for a crime she did not commit -- the stuff of soap writers' fecund imaginations. But when Barbara was "diagnosed" with oral cancer in 2008, the script was ripped from the real life drama of the actress who plays her and fact-checked with the Oral Cancer Foundation, for which Pinter is now the spokesperson. Warning the public about this little-known cancer and about a simple 3--5 minute screening your dentist can do has become a mission for Pinter. "The screening is painless," she said in an interview with the Westport News. "And you don't have to take your clothes off!" Oral cancer kills more people each year than cervical, skin or prostate cancer, yet when found early, there is an 80 to 90 percent survival rate. She took her private health battle public first on the CBS Early Show, filmed a PSA for the Oral Cancer Foundation, a birthday commercial for the American Cancer Society and has spoken before such groups as the 2009 graduating class. University's School of Dentistry. Pinter first noticed that her speech was slurring in December 2005 but her dentist assured the then 52-year-old actress that it was just her teeth shifting. Then in July 2006, [...]

Biodesix: a new way to inform cancer treatment selection

Source: Author: staff "One data point doesn’t tell you very much in most cases,” comments David Brunel, CEO of Biodesix, a medical diagnostics company based in Broomfield, Colorado. This principle guides Biodesix’s approach to developing diagnostics which aim to indentify a patient’s expected response to a particular therapeutic. Biodesix’s technology evaluates multiple biomarkers – identified with a blood sample and analyzed using mass spectrometry – to predict response rather than trying to make a determination based on a single biomarker. VeriStrat® is the company’s first test, categorizing the expected prognosis of patients with non-small cell lung cancer (NSCLC) who receive treatment with a class of targeted cancer drugs know as epidermal growth factor receptor inhibitors or EGFR-Is. Tarceva (erlotinib) is an EGFR-I commonly used to treat NSCLC patients. VeriStrat classifies patients as either VeriStrat Good or VeriStrat Poor and this information can assist a physician’s decision to pursue treatment with Tarceva or another treatment. To complete a VeriStrat test, a patient’s blood is drawn and sent to the Biodesix lab in Aurora, Colorado. There the sample is run through a mass spectrometer and the data generated from the mass spectrometer is then processed through a proprietary software algorithm to determine a patient’s VeriStrat classification. The algorithm was developed using samples and subsequent disease response data from patients who had received treatment with an EGFR-I. According to Brunel, “several markers were identified in the group of patients whose cancer is prone to respond to EGFR-I treatment versus those whose cancer [...]

Adding chemo helps head, neck cancer patients

Source: HealthDayNews Author: Staff TUESDAY, Oct. 27 (HealthDay News) -- Combining chemotherapy with radiation treatment for patients with advanced head and neck cancer increases their event-free survival to 2.2 years from just one year with radiotherapy alone, finds a new study. According to the study authors, "events" include cancer recurrence, new tumors or death. British researchers looked at the 10-year outcomes of 966 patients with locally advanced head and neck cancer. Those who hadn't undergone surgery for their cancer were randomly assigned to one of four groups: radiotherapy alone (233 patients); two courses of simultaneous (SIM) chemotherapy given at the same time as radiotherapy (166 patients); two courses of chemotherapy after (subsequent -- SUB) completing radiotherapy (160 patients); or both SIM and SUB (154 patients). Patients who'd had surgery were randomly assigned to radiotherapy alone (135 patients) or SIM alone (118 patients). Overall, non-platinum-based chemotherapy given at the same time as radiotherapy reduced deaths and cancer recurrence in patients who hadn't undergone surgery, with acceptable toxicity. But patients who'd undergone surgery didn't benefit from this combined treatment. The researchers also found that chemotherapy given after radiotherapy was ineffective, didn't improve survival, and doubled the rate of toxicity. Among patients who didn't have surgery, median survival time was 2.6 years in the radiotherapy group, and 4.7 years, 2.3 years and 2.7 years, respectively, in patients who received SIM alone, SUB alone, and SIM plus SUB. Median event-free survival among patients who didn't have surgery was one year in the radiotherapy group, 2.2 years in [...]

Curry kills gullet cancer cells

Source: Author: Richard Alleyne, Science Correspondent Scientists based at the Cork Cancer Research Centre in Ireland treated oesophageal cancer cells with curcumin – a chemical found in the curry spice tumeric. They found that curcumin started to kill cancer cells within 24 hours. The cells also began to digest themselves, according to the research, published in the British Journal of Cancer. “Scientists have known for a long time that natural compounds have the potential to treat faulty cells that have become cancerous and we suspected that curcumin might have therapeutic value. "Dr Geraldine O’Sullivan-Coyne, a medical researcher in our lab, had been looking for new ways of killing resistant oesophageal cancer cells. "She tested curcurmin on resistant cells and found that they started to die using an unexpected system of cell messages." Normally, faulty cells die by committing programmed suicide – or apoptosis – which occurs when proteins called caspases are "switched on" in cells. But these cells showed no evidence of suicide and the addition of a molecule that inhibits caspases and stops this ‘switch being flicked’, made no difference to the number of cells which died. This suggested that curcumin attacked the cancer cells using an alternative cell signalling system. Each year around 7,800 people are diagnosed with oesophageal cancer in the UK. Less than 20 per cent of people survive oesophageal cancer beyond five years. It is the sixth most common cause of cancer death and accounts for around five per cent of all UK cancer [...]

Does the negative node count affect disease-free survival in early-stage oral cavity cancer?

Source: J Oral Maxillofac Surg, November 1, 2009; 67(11): 2473-5 Authors: FL Ampil, G Caldito, GE Ghali, and RG Baluna Purpose: We performed a retrospective study to determine whether there is a relationship between disease-free survival and negative lymph node count in patients with resected early-stage oral cavity cancers. Materials and Methods: Of the 526 individuals diagnosed with carcinoma of the oral cavity between 1998 and 2005, 52 had undergone primary tumor resection and lymph node dissection of the neck for stage I or II disease. With a mean count of 27 examined negative nodes, these 52 patients were separated into groups with fewer than 27 or > or = 27 uninvolved lymph nodes and compared for disease-free survival. Results: The tumor recurred or progressed in 10 patients (19%) during a median follow-up of 27 months. The 2-year disease-free survival rates were 75% and 78% in individuals with fewer than 27 and > or = 27 uninvolved node counts, respectively (P > .78). Conclusion: The removal of a greater number of regional, uninvolved cervical lymph nodes does not correlate with disease-free survival in this particular cohort of patients.

Cancers can vanish without treatment, but how?

Source: Author: Gina Kolata Call it the arrow of cancer. Like the arrow of time, it was supposed to point in one direction. Cancers grew and worsened. But as a paper in The Journal of the American Medical Association noted last week, data from more than two decades of screening for breast and prostate cancer call that view into question. Besides finding tumors that would be lethal if left untreated, screening appears to be finding many small tumors that would not be a problem if they were left alone, undiscovered by screening. They were destined to stop growing on their own or shrink, or even, at least in the case of some breast cancers, disappear. “The old view is that cancer is a linear process,” said Dr. Barnett Kramer, associate director for disease prevention at the National Institutes of Health. “A cell acquired a mutation, and little by little it acquired more and more mutations. Mutations are not supposed to revert spontaneously.” So, Dr. Kramer said, the image was “an arrow that moved in one direction.” But now, he added, it is becoming increasingly clear that cancers require more than mutations to progress. They need the cooperation of surrounding cells and even, he said, “the whole organism, the person,” whose immune system or hormone levels, for example, can squelch or fuel a tumor. Cancer, Dr. Kramer said, is a dynamic process. It was a view that was hard for some cancer doctors and researchers to accept. But some of [...]
