VA Services for Patients With Comorbidities
This case highlights several distinct aspects of VA health care that make it possible to safely treat individuals with complex comorbidities. One important aspect of this was collaboration with the CLC to admit the veteran for his initial treatment after a positive cocaine test. CLC admission was nonpunitive and allowed ongoing involvement in the VA community. This provided an essential, safe, and structured environment in which 6 cycles of chemotherapy could be delivered.
Although the patient left the CLC after 2 months due to floor restrictions negatively impacting his quality of life and ability to spend time with close friends, several important events occurred during this stay. First, the patient established close relationships with the CLC staff and the palliative care team; both groups followed him throughout his inpatient and outpatient care. These relationships proved essential throughout his care as they were the foundation of difficult conversations about substance use, treatment adherence, and eventually, transition to hospice.
In addition, the opportunity to administer 6 cycles of chemotherapy at the CLC was enough to lead to clinical benefit and radiographic response to treatment. Clinical benefits while in the CLC included maintenance of a good appetite, 15-lb weight gain and preserved performance status (ECOG [Eastern Cooperative Group]-1), which allowed him to actively participate in multiple social and recreational activities while in the CLC. From early conversations, this patient was clear that he wanted treatment as long as his life could be prolonged with good quality of life. Having evidence of the benefit of treatment, at least initially, increased the patient’s confidence in treatment. There were a few conversations when the challenges of treatment mounted (eg, pain, needs for abstinence from cocaine prior to admission for chemotherapy, frequent doctor appointments), and the patient would remind himself of these data to recommit himself to treatment. The opportunity to admit him to the inpatient VA facility, including bed availability for 3 days during his treatment once he left the CLC was important. This plan to admit the patient following a negative urine toxicology test for cocaine was made collaboratively with the veteran and the oncology and palliative care teams. The plan allowed the patient to achieve his treatment goals while maintaining his safety and reducing theoretical cardiac toxicities with his cancer treatment.
Finally, the availability of a multidisciplinary team approach including palliative care, oncology, psychology, addiction medicine and addiction psychiatry, was critical for addressing the veteran’s malignant pain. Palliative care worked in close collaboration with the ORC to prescribe and renew pain medications. ORC offered ongoing consultation on pain management in the context of OUD. As the veteran’s cancer progressed and functional decline prohibited his daily attendance at the community methadone clinic, palliative care and ORC met with the methadone clinic to arrange a less frequent methadone pickup schedule (the patient previously needed daily pickup). Non-VA settings may not have access to these resources to safely treat the biopsychosocial issues that arise in complex cases.
Substance Use and Cancer Treatments
This case raises several critical questions for oncologic care. Cocaine and fluorouracil are both associated with cardiotoxicity, and many oncologists would not feel it is safe to administer a regimen containing fluorouracil to a patient with active cocaine use. The National Comprehensive Cancer Network (NCCN) panel recommends FOLFIRINOX as a preferred category 1 recommendation for first-line treatment of patients with advanced pancreas cancer with good performance status.10 This recommendation is based on the PRODIGE trial, which has shown improved overall survival (OS): 11.1 vs 6.8 months for patients who received single-agent gemcitabine.11 If patients are not candidates for FOLFIRINOX and have good performance status, the NCCN recommends gemcitabine plus albumin-bound paclitaxel with category 1 level of evidence based on the IMPACT trial, which showed improvement in OS (8.7 vs 6.6 months compared with single-agent gemcitabine).12
Some oncologists may have additional concerns administering fluorouracil treatment alternatives (such as gemcitabine and albumin-bound paclitaxel) to individuals with active SUD because of concerns about altered mental status impacting the ability to report important adverse effects. In the absence of sufficient data, HCPs must determine whether they feel it is safe to administer these agents in individuals with active cocaine use. However, denying these patients the possible benefits of standard-of-care life-prolonging therapies without established data raises concerns regarding the ethics of such practices. There is concern that the stigma surrounding cocaine use might contribute to withholding treatment, while treatment is continued for individuals taking prescribed stimulant medications that also have cardiotoxicity risks. VA health care facilities are uniquely situated to use all available resources to address these issues using interprofessional patient-centered care and determine the most optimal treatment based on a risk/benefit discussion between the patient and the HCP.
