HPV Case Study Read the case study and, using your knowledge of human biology and other resources indicated, answer the questions that follow. Save and submit to the drop box. Bob is healthy 44-year old and father of 2 who recently completed his first marathon. Life was good; he was in the best shape of his life, gainfully employed and happily supporting and raising his family at home. However, Bob has been sporadically dealing with a sore throat for the better part of the past year. The symptoms would come and go but for the most part consistently there. Eventually, he went to see his doctor who examined his throat and saw an inflamed red area in the back of his throat and prescribed a course of antibiotics presuming the sore throat was caused by a bacterial infection. Bob adhered to the course of antibiotic therapy but the sore throat still persisted. At this point, the doctor felt as if perhaps Bob had post-nasal drip perhaps caused by a viral infection or allergies and suggested trying a nasal spray and room humidifier. Unfortunately, Bob’s symptoms continued and he was eventually referred to an Ear, Nose and Throat (ENT) specialist who also saw the lesion and ordered a MRI. Bob anxiously awaited the results from the MRI and no sooner did he receive a phone call from the ENT stating that she would like to perform a biopsy. That week the biopsy was performed and quickly read by a pathologist who diagnosed the lesion as oropharyngeal cancer. The cancer was a squamous cell carcinoma of the right tonsil (1.2 cm). When Bob received the news of his diagnosis, he felt numbed by the news. He felt as if this certainly must have been a mistake as he is living a healthy lifestyle which included healthy eating, exercise and limited amounts of alcohol during social events. However, the news was not a mistake and now he must ask some serious questions regarding his future. The pathologist also stated that the lesion was classified to be HPV+ (Human Papillomavirus positive). Bob quickly discovered through research that HPV is the most common sexually transmitted infection in the United States, known to cause cervical cancer in women and is currently being vaccinated against. Interestingly this finding is also favorable with regards to the outcome of the oropharyngeal cancer that Bob has. 1.
