What are Bruce’s options at this point? Bruce and his parents moved to a semi-tropical region of the United States when he was about 3 years old. He loved to be outside year-round and swim, surf, snorkel, and play baseball. Bruce was fair-skinned, and in his childhood years, was sunburned quite often. In his teen years, he began using sunscreens, and although he never tanned very much, he did not have the painful sunburns of his younger years. After graduation from the local community college, Bruce wanted an outdoor job and was hired at a dive shop. He took people out to one of the local reefs to snorkel and scuba dive. He didn’t give a second thought to sun exposure because he used sunscreen. His employer did not provide health insurance, so Bruce did not go for annual checkups, and tried to stay in good health. In his late 20s, Bruce was injured trying to keep a tourist from getting caught between the dive boat and the dock. He went to an internist, who treated his injury and told Bruce he was going to give him a complete physical exam. During the exam, the internist noticed a discolored patch of skin on Bruce’s back. She told him that she suspected Bruce had skin cancer and referred him to a dermatologist, who biopsied the patch. At a follow-up visit, Bruce was told that he had melanoma, a deadly form of skin cancer. Further testing revealed that the melanoma had spread to his liver and his lungs. The dermatologist explained that treatment options at this stage are limited. The drugs available for chemotherapy have only temporary effects, and surgery is not effective for melanoma at this stage. The dermatologist recommended that Bruce consider entering a clinical trial that was testing a DNA vaccine for melanoma treatment. These vaccines deliver DNA encoding a gene expressed by the cancer cells to the immune system. This primes the immune system to respond by producing large quantities of antibodies that destroy melanoma cells wherever they occur in the body. A clinical trial using one such DNA vaccine was being conducted at a nearby medical center, and Bruce decided to participate. At the study clinic, Bruce learned that he would be in a Phase Ill trial, comparing the DNA vaccine against the standard treatment, which is chemotherapy, and that he would be randomly assigned to receive either the DNA vaccine or the chemotherapy. He was disappointed to learn this. He thought he would be receiving the DNA vaccine.

Expert Solution & Answer

Summary Introduction

To determine: The treatment options for patient B at the advanced stage of melanoma.

Introduction: Melanoma is the most serious form of skin cancer. Overexposure to the sun is the major risk factor to cause melanoma in any individual. Mutation in the melanocytes leads to melanoma.

Explanation of Solution

When patient B was diagnosed with melanoma, he was at advanced stage of skin cancer. Cancer has already spread in his liver and lungs. He was told by his dermatologist that treatment options are limited at this stage. The chemotherapy has only temporary effects and surgery is useless at this stage of melanoma.

Furthermore, patient B’s dermatologist suggested him to enter the clinical trial in which DNA vaccine will be tested for melanoma treatment. However, after joining the clinical trial patient B got to know that it was a phase III clinical trial. Phase III trial is a comparative study between two treatments and he would randomly be assigned DNA vaccine or chemotherapy.

Hence, patient B has the option to stay in clinical trial to obtain a DNA vaccine or he can take less effective chemotherapy at this stage.
