A 75-year-old woman with metastatic colon cancer comes to the physician requesting assistance in ending her life. She states: “I just can't take it anymore; the pain is unbearable. Please help me die.” Current medications include 10 mg oral hydrocodone every 12 hours. Her cancer has progressed despite chemotherapy and she is very frail. She lives alone and has no close family. Which of the following is the most appropriate initial action by the physician?
Q2
A 52-year-old man with stage IV melanoma comes to the physician with his wife for a routine follow-up examination. He was recently diagnosed with new bone and brain metastases despite receiving aggressive chemotherapy but has not disclosed this to his wife. He has given verbal consent to discuss his prognosis with his wife and asks the doctor to inform her of his condition because he does not wish to do so himself. She is tearful and has many questions about his condition. Which of the following would be the most appropriate statement by the physician to begin the interview with the patient's wife?
Q3
You conduct a medical research study to determine the screening efficacy of a novel serum marker for colon cancer. The study is divided into 2 subsets. In the first, there are 500 patients with colon cancer, of which 450 are found positive for the novel serum marker. In the second arm, there are 500 patients who do not have colon cancer, and only 10 are found positive for the novel serum marker. What is the overall sensitivity of this novel test?

Question 1: A 75-year-old woman with metastatic colon cancer comes to the physician requesting assistance in ending her life. She states: “I just can't take it anymore; the pain is unbearable. Please help me die.” Current medications include 10 mg oral hydrocodone every 12 hours. Her cancer has progressed despite chemotherapy and she is very frail. She lives alone and has no close family. Which of the following is the most appropriate initial action by the physician?
A. Consult with the local ethics committee
B. Submit a referral to psychiatry
C. Submit a referral to hospice care
D. Increase her pain medication dose (Correct Answer)
E. Initiate authorization of physician-assisted suicide
Explanation: ***Increase her pain medication dose***
- The patient's request to end her life is directly linked to "unbearable pain" and her current pain regimen (10 mg hydrocodone every 12 hours) is **sub-therapeutic** for metastatic cancer, indicating inadequate pain control.
- Addressing the **underlying cause** of her distress, which is severe pain, with appropriate analgesia is the immediate and most ethical first step in palliative care.
*Consult with the local ethics committee*
- While ethical considerations are paramount in end-of-life care, this is not the **initial action** as the patient's pain, a modifiable factor, needs to be addressed first.
- An ethics committee consultation would be more appropriate if adequate pain control has been attempted and the patient's request persists or if there are complex ethical dilemmas beyond immediate symptom management.
*Submit a referral to psychiatry*
- Although patients with severe illness may experience depression, the primary stated reason for her request is **unbearable pain**, which is a physical symptom requiring immediate medical attention.
- A psychiatric referral might be warranted if, after adequate pain management, the patient continues to express persistent desires for death or exhibits symptoms of a treatable mood disorder, but it is not the *initial* step.
*Submit a referral to hospice care*
- This is an appropriate step for a patient with metastatic colon cancer and frailty, as hospice provides **comprehensive palliative care**.
- However, the **immediate priority** is addressing her acute and inadequately treated pain, which is the stated reason for her distress and request for assistance in dying.
*Initiate authorization of physician-assisted suicide*
- Physician-assisted suicide is **illegal** in most jurisdictions and ethically controversial, and palliative care principles prioritize relieving suffering rather than ending life.
- The patient's request stems from **unmanaged pain**, which is a treatable condition, making physician-assisted suicide an inappropriate and premature consideration.
Question 2: A 52-year-old man with stage IV melanoma comes to the physician with his wife for a routine follow-up examination. He was recently diagnosed with new bone and brain metastases despite receiving aggressive chemotherapy but has not disclosed this to his wife. He has given verbal consent to discuss his prognosis with his wife and asks the doctor to inform her of his condition because he does not wish to do so himself. She is tearful and has many questions about his condition. Which of the following would be the most appropriate statement by the physician to begin the interview with the patient's wife?
A. Have you discussed a living will or goals of care together?
B. We should talk about how we can manage his symptoms with additional chemotherapy.
C. Why do you think your husband has not discussed his medical condition with you?
D. What is your understanding of your husband's current condition? (Correct Answer)
E. Your husband has end-stage cancer, and his prognosis is poor.
Explanation: ***What is your understanding of your husband's current condition?***
- This statement initiates the conversation by **assessing the wife's current knowledge** and emotional state, which is crucial for delivering sensitive and appropriate information.
- It allows the physician to tailor the discussion to her specific understanding and concerns, ensuring that information is delivered compassionately and effectively.
*Have you discussed a living will or goals of care together?*
- This question is too abrupt and **premature** as an opening, as the wife is clearly distressed and unaware of the full severity of her husband's condition.
- Discussions about end-of-life planning should only occur after the patient's wife has a clear understanding of the diagnosis and prognosis, and has processed this information.
*Your husband has end-stage cancer, and his prognosis is poor.*
- While factual, this statement is **too blunt and lacks empathy** for an opening, especially given the wife's emotional state and lack of prior knowledge.
- Delivering such devastating news directly without first assessing her understanding or providing context can be traumatic and impede effective communication.
*We should talk about how we can manage his symptoms with additional chemotherapy.*
- This statement implies a focus on further aggressive treatment which may not be appropriate given the **new bone and brain metastases** and aggressive prior chemotherapy, suggesting a limited benefit of more chemotherapy.
- It also **diverts from the primary need to discuss the overall prognosis** and the patient's rapidly declining condition, which the doctor has been asked to convey.
*Why do you think your husband has not discussed his medical condition with you?*
- This question is **accusatory** and places blame on either the patient or the wife, which is inappropriate and unhelpful in a sensitive medical discussion.
- It shifts the focus away from providing medical information and empathy towards a speculative and potentially confrontational topic.
Question 3: You conduct a medical research study to determine the screening efficacy of a novel serum marker for colon cancer. The study is divided into 2 subsets. In the first, there are 500 patients with colon cancer, of which 450 are found positive for the novel serum marker. In the second arm, there are 500 patients who do not have colon cancer, and only 10 are found positive for the novel serum marker. What is the overall sensitivity of this novel test?
A. 450 / (450 + 10)
B. 490 / (10 + 490)
C. 490 / (50 + 490)
D. 450 / (450 + 50) (Correct Answer)
E. 490 / (450 + 490)
Explanation: ***450 / (450 + 50)***
- **Sensitivity** is defined as the proportion of actual positive cases that are correctly identified by the test.
- In this study, there are **500 patients with colon cancer** (actual positives), and **450 of them tested positive** for the marker, while **50 tested negative** (500 - 450 = 50). Therefore, sensitivity = 450 / (450 + 50) = 450/500 = 0.9 or 90%.
*450 / (450 + 10)*
- This formula represents **Positive Predictive Value (PPV)**, which is the probability that a person with a positive test result actually has the disease.
- It incorrectly uses the total number of **test positives** in the denominator (450 true positives + 10 false positives) instead of the total number of diseased individuals, which is needed for sensitivity.
*490 / (10 + 490)*
- This is actually the correct formula for **specificity**, not sensitivity.
- Specificity = TN / (FP + TN) = 490 / (10 + 490) = 490/500 = 0.98 or 98%, which measures the proportion of actual negative cases correctly identified.
- The question asks for sensitivity, not specificity.
*490 / (50 + 490)*
- This formula incorrectly mixes **true negatives (490)** with **false negatives (50)** in an attempt to calculate specificity.
- The correct specificity formula should use false positives (10), not false negatives (50), in the denominator: 490 / (10 + 490).
*490 / (450 + 490)*
- This calculation incorrectly combines **true negatives (490)** and **true positives (450)** in the denominator, which does not correspond to any standard epidemiological measure.
- Neither sensitivity nor specificity uses both true positives and true negatives in the denominator.
Question 4: A 19-year-old woman is diagnosed with metastatic Ewing sarcoma. She has undergone multiple treatments without improvement. She decides to stop treatment and pursue only palliative care. She is of sound mind and has weighed the benefits and risks of this decision. The patient’s mother objects and insists that treatments be continued. What should be done?
A. Try to seek additional experimental treatments that are promising.
B. Follow the wishes of the patient’s mother as she has decision making power for the patient.
C. Continue treatments until the patient has a psychiatric evaluation.
D. Continue treatment because otherwise, the patient will die.
E. Halt treatments and begin palliative care. (Correct Answer)
Explanation: ***Halt treatments and begin palliative care.***
- An adult patient of **sound mind** has the right to refuse medical treatment, even if that refusal may lead to death. This principle is a cornerstone of **patient autonomy**.
- The patient has clearly expressed her wishes after weighing the benefits and risks, making her decision legally and ethically binding.
*Try to seek additional experimental treatments that are promising.*
- While seeking additional treatments might be an option if the patient desired it, forcing such treatments against her will violates her **autonomy** and right to self-determination.
- The case states the patient has decided to stop treatment, making further treatment exploration against her expressed wishes.
*Follow the wishes of the patient’s mother as she has decision making power for the patient.*
- The patient is 19 years old, making her a **legal adult**, and therefore her mother does not have decision-making power over her medical care.
- The patient's mother's wishes, while understandable from an emotional perspective, do not supersede the **competent adult patient's** right to make her own medical decisions.
*Continue treatments until the patient has a psychiatric evaluation.*
- The patient is described as being of "sound mind" and having "weighed the benefits and risks," indicating she is making an informed decision.
- Requesting a psychiatric evaluation without clear evidence of impaired mental capacity would be a disrespectful and unethical attempt to override her **autonomously made decision**.
*Continue treatment because otherwise, the patient will die.*
- While it is true that stopping treatment will likely lead to death, a **competent adult patient** has the right to refuse life-sustaining treatment.
- The patient's right to **autonomy** and control over her own body takes precedence over the desire of others (including medical professionals or family) to prolong life against her will.
Question 5: A 57-year-old man presents to his oncologist to discuss management of small cell lung cancer. The patient is a lifelong smoker and was diagnosed with cancer 1 week ago. The patient states that the cancer was his fault for smoking and that there is "no hope now." He seems disinterested in discussing the treatment options and making a plan for treatment and followup. The patient says "he does not want any treatment" for his condition. Which of the following is the most appropriate response from the physician?
A. "You seem upset at the news of this diagnosis. I want you to go home and discuss this with your loved ones and come back when you feel ready to make a plan together for your care."
B. "It must be tough having received this diagnosis; however, new cancer therapies show increased efficacy and excellent outcomes."
C. "It must be very challenging having received this diagnosis. I want to work with you to create a plan." (Correct Answer)
D. "We are going to need to treat your lung cancer. I am here to help you throughout the process."
E. "I respect your decision and we will not administer any treatment. Let me know if I can help in any way."
Explanation: ***"It must be very challenging having received this diagnosis. I want to work with you to create a plan."***
- This response **acknowledges the patient's emotional distress** and feelings of guilt and hopelessness, which is crucial for building rapport and trust.
- It also gently **re-engages the patient** by offering a collaborative approach to treatment, demonstrating the physician's commitment to supporting him through the process.
*"You seem upset at the news of this diagnosis. I want you to go home and discuss this with your loved ones and come back when you feel ready to make a plan together for your care."*
- While acknowledging distress, sending the patient home without further engagement **delays urgent care** for small cell lung cancer, which is aggressive.
- This response might be perceived as dismissive of his immediate feelings and can **exacerbate his sense of hopelessness** and isolation.
*"It must be tough having received this diagnosis; however, new cancer therapies show increased efficacy and excellent outcomes."*
- This statement moves too quickly to treatment efficacy without adequately addressing the patient's current **emotional state and fatalism**.
- While factual, it **lacks empathy** for his personal feelings of blame and hopelessness, potentially making him feel unheard.
*"We are going to need to treat your lung cancer. I am here to help you throughout the process."*
- This response is **too directive and authoritarian**, which can alienate a patient who is already feeling guilty and resistant to treatment.
- It fails to acknowledge his stated feelings of "no hope now" or his disinterest in treatment, which are critical to address before discussing the necessity of treatment.
*"I respect your decision and we will not administer any treatment. Let me know if I can help in any way."*
- While respecting patient autonomy is vital, immediately accepting a patient's decision to refuse treatment without exploring the underlying reasons (e.g., guilt, hopelessness, lack of information) is **premature and potentially harmful**.
- The physician has a responsibility to ensure the patient is making an informed decision, especially for a rapidly progressing condition like small cell lung cancer.
