Prognostic disclosure to patients with cancer near the end of life.

BACKGROUND: Patients' understanding of their prognosis informs numerous medical and nonmedical decisions, but patients with cancer and their physicians often have disparate prognostic expectations. OBJECTIVE: To determine whether physician behavior might contribute to the disparity between patients' and physicians' prognostic expectations. DESIGN: Prospective cohort study. SETTING: Five hospices in Chicago, Illinois. PATIENTS: 326 patients with cancer. INTERVENTION: Physicians formulated survival estimates and also indicated the survival estimates that they would communicate to their patients if the patients insisted. MEASUREMENTS: Comparison of the formulated and communicated prognoses. RESULTS: For 300 of 311 evaluable patients (96.5%), physicians were able to formulate prognoses. Physicians reported that they would not communicate any survival estimate 22.7% (95% CI, 17.9% to 27.4%) of the time, would communicate the same survival estimate they formulated 37% (CI, 31.5% to 42.5%) of the time, and would communicate a survival estimate different from the one they formulated 40.3% (CI, 34.8% to 45.9%) of the time. Of the discrepant survival estimates, most (70.2%) were optimistically discrepant. Multivariate analysis revealed that older patients were more likely to receive frank survival estimates, that the most experienced physicians and the physicians who were least confident about their prognoses were more likely to favor no disclosure over frank disclosure, and that female physicians were less likely to favor frank disclosure over pessimistically discrepant disclosure. CONCLUSIONS: Physicians reported that even if patients with cancer requested survival estimates, they would provide a frank estimate only 37% of the time and would provide no estimate, a conscious overestimate, or a conscious underestimate most of the time (63%). This pattern may contribute to the observed disparities between physicians' and patients' estimates of survival.

Chemotherapy in the management of squamous-cell carcinoma of the head and neck.

Previously reserved for palliation, chemotherapy is now also a central component of several curative approaches to the management of patients with advanced-stage head and neck cancer. Here we review the results of both induction chemotherapy and chemoradiotherapy trials in patients with curable disease, and chemotherapy trials in patients with recurrent and metastatic disease, and we highlight current areas of investigation. Compared with traditional treatment modalities, chemotherapy given on induction schedules to patients with advanced laryngeal cancer allows greater organ preservation without compromise to survival; when given concomitantly with radiotherapy to patients with resectable or unresectable advanced disease, chemotherapy again improves survival.

Extent and determinants of error in doctors' prognoses in terminally ill patients: prospective cohort study.

OBJECTIVE: To describe doctors' prognostic accuracy in terminally ill patients and to evaluate the determinants of that accuracy. DESIGN: Prospective cohort study. SETTING: Five outpatient hospice programmes in Chicago. PARTICIPANTS: 343 doctors provided survival estimates for 468 terminally ill patients at the time of hospice referral. MAIN OUTCOME MEASURES: Patients' estimated and actual survival. RESULTS: Median survival was 24 days. Only 20% (92/468) of predictions were accurate (within 33% of actual survival); 63% (295/468) were overoptimistic and 17% (81/468) were overpessimistic. Overall, doctors overestimated survival by a factor of 5.3. Few patient or doctor characteristics were associated with prognostic accuracy. Male patients were 58% less likely to have overpessimistic predictions. Non-oncology medical specialists were 326% more likely than general internists to make overpessimistic predictions. Doctors in the upper quartile of practice experience were the most accurate. As duration of doctor-patient relationship increased and time since last contact decreased, prognostic accuracy decreased. CONCLUSION: Doctors are inaccurate in their prognoses for terminally ill patients and the error is systematically optimistic. The inaccuracy is, in general, not restricted to certain kinds of doctors or patients. These phenomena may be adversely affecting the quality of care given to patients near the end of life.

Extent and determinants of error in physicians' prognoses in terminally ill patients: prospective cohort study.

Objectives To describe physicians' prognostic accuracy in terminally ill patients and to evaluate the determinants of that accuracy. Design Prospective cohort study. Setting Five outpatient hospice programs in Chicago. Participants A total of 343 physicians provided survival estimates for 468 terminally ill patients at the time of hospice referral. Main outcome measures Patients' estimated and actual survival. Results Median survival was 24 days. Of 468 predictions, only 92 (20%) were accurate (within 33% of actual survival); 295 (63%) were overoptimistic, and 81 (17%) were overpessimistic. Overall, physicians overestimated survival by a factor of 5.3. Few patient or physician characteristics were associated with prognostic accuracy. Male patients were 58% less likely to have overpessimistic predictions. Medical specialists excluding oncologists were 326% more likely than general internists to make overpessimistic predictions. Physicians in the upper quartile of practice experience were the most accurate. As the duration of the doctor-patient relationship increased and time since last contact decreased, prognostic accuracy decreased. Conclusions Physicians are inaccurate in their prognoses for terminally ill patients, and the error is systematically optimistic. The inaccuracy is, in general, not restricted to certain kinds of physicians or patients. These phenomena may be adversely affecting the quality of care given to patients near the end of life.

Paradoxes in cancer patients' advance care planning.

PURPOSE: To determine the frequency of advance care planning (ACP) in hospitalized cancer patients and to assess their reactions to a proposed policy in which medical housestaff would offer to discuss ACP at the time of hospital admission. METHODS: Structured interviews with 111 consecutively admitted cancer patients on the oncology inpatient service of a tertiary care medical center. RESULTS: We found that 69% (77/111) of patients had discussed their advance care preferences with someone, usually a family member, and 33% (37/111) had completed at least one formal advance directive (e.g., a living will or durable power of attorney for health care); 32% (36/111) had done both; and 30% (33/111) had done neither. However, only 9% (10/111) of patients reported having discussed their advance care preferences with their clinic oncologists and only 23% (23/101) of the remaining patients stated that they wished to do so. By contrast, 58% (64/110) of patients supported a policy in which medical housestaff would offer to discuss these advance care preferences as a part of the admission history. CONCLUSIONS: Our data suggest that while oncology inpatients frequently have ACPs that they discuss with family and/or document in formal advance directives, they rarely discuss or wish to discuss these ACPs with clinic oncologists. We also show that most of the reticent patients would nevertheless consider discussing the same ACPs with admitting housestaff on the day of hospital admission.

Some elements of prognosis in terminal cancer.

Predicting the survival of terminal cancer patients is a difficult task. To better understand this difficulty, we divide prognostication into two distinct elements: foreseeing and foretelling. Foreseeing is a physician's silent cognitive estimate about a patient's illness. Foretelling is the physician's communication of that prediction to the patient or significant others. In this article, we review the impact of each element of prognosis on physicians' overall prognostic accuracy. We show that physicians often make unwitting, large, and generally optimistic errors in foreseeing patients' prognoses. They also may make more conscious, but equally large, optimistic errors in foretelling prognoses to patients. The net effect is that patients may become twice removed from the truth about their illness, both times toward a falsely optimistic prognosis. We also describe the possible consequences of these optimistic prognostic errors. Finally, we review techniques that may improve physicians' prognostic accuracy. We conclude that part of the challenge of providing humane, compassionate end-of-life care to cancer patients may involve accurately foreseeing and foretelling their prognoses.

The oral fluoropyrimidines in cancer chemotherapy.

A classic example of a rationally developed class of anticancer drugs, the fluoropyrimidines are now the focus of further rational approaches to cancer chemotherapy as they are transformed into oral formulations. Given alone, oral 5-fluorouracil (5-FU) has erratic absorption and nonlinear pharmacokinetics. However, when oral 5-FU is given as a prodrug and/or paired with a dihydropyrimidine dehydrogenase inhibitor, the resultant 5-FU has linear pharmacokinetics that may approximate the less myelosuppressive continuous i.v. infusion schedule of 5-FU administration without the use of infusion catheters and pumps. We review the preclinical and clinical experience of several of the oral fluoropyrimidines.

Oncogenic osteomalacia as a harbinger of recurrent osteosarcoma.

Discussion. Oncogenic osteomalacia is a rare paraneoplastic syndrome of skeletal demineralization from renal phosphate loss. Patients with this disorder have the characteristic clinical, laboratory, and radiographic findings of hyperphosphaturic osteomalacia. Although the pathophysiology has not yet been clearly delineated, a humoral factor produced by the tumor is suspected to be the cause.Purpose. We report the first case of oncogenic osteomalacia that improved with chemotherapy, discuss this paraneoplastic syndrome, and review the medical literature regarding its etiology.

An occult cause of persistent nausea and vomiting.

We report a patient with multiple negative evaluations during emergency department visits and inpatient admissions for unexplained, intermittent nausea, vomiting, and abdominal pain. The etiology of her symptoms was not revealed until her 13th hospital visit, when head magnetic resonance imaging suggested active neurocysticercosis. Central etiologies should be considered for intractable nausea and vomiting in neurologically intact patients even if head computed-assisted tomography scan is negative.
