  Introduction:
   The decision to stop anti-cancer treatment is fraught with many challenges for the oncologist, the patient, and their caregivers. This review examines the special considerations surrounding the decision to cease chemotherapy in terminally ill cancer patient. <b>Methods: </b>A comprehensive literature search was conducted to find relevant publications on chemotherapy cessation. A total of 2700 records were retrieved and 141 were identified as eligible for inclusion in this review. <b>Results: </b>Palliative chemotherapy does not achieve the goal of tumor-related symptom reduction for patients who have experienced progressive disease with more than two prior lines of chemotherapy. ECOG performance status is a crucial predictor of response to therapy and chemotherapy-related complications. Challenges to stopping chemotherapy at the end of life are multifactorial and are both patient and physician-driven. Racial, ethnic, and income-based disparities are seen in the timing and quality of end-of-life conversations offered by physicians to their patients. <b>Conclusions:</b> The decision to cease chemotherapy is one that should be approached with careful consideration and accurate information. Clear communication, compassion and empathy are important components to the therapeutic relationship. Early involvement of palliative care and clear conversations about prognosis and the expected utility of further chemotherapy is essential to conduct the best possible care for cancer patients at the end of life.

Introduction</title><p>Chemotherapy, a common modality for the treatment and management of cancer, is utilized for curative intent, the prolongation of life, and palliation of symptoms. While advances in treatment have led to increased survival and improved treatment outcomes, many patients will ultimately succumb to their disease. For patients with continued disease progression despite multiple lines of chemotherapy, discussions that treatment is no longer effective can be difficult. When chemotherapy is no longer effective, what is the appropriate next step in caring for the patient? What exactly does cessation of chemotherapy mean for the patient? How is such a decision made? There is a profound existential and emotional transition point between active treatment and best supportive care where goals of treatment are assessed, and the decision is made to withhold chemotherapy. There is little data addressing the various psychological, physical, and medical aspects of this unique turning point. This review examines the special considerations surrounding the decision to cease chemotherapy in terminally ill cancer patient.</p></sec><sec id="s2"><title>2. Methods</title><p>A comprehensive literature search was conducted to find relevant publications on chemotherapy cessation. The search was conducted on the National Center for Biotechnology Information (NCBI) and PubMed (U.S. National Library of Medicine at the National Institutes of Health). The keywords used in the search included “chemotherapy”, “chemotherapy resistance”, “chemotherapy cessation”, “palliative chemotherapy”, “recurrent cancer and prognosis”, “best supportive care”, “medical futility”, and “end-of-life.”</p><p>Inclusion and exclusion criteria were applied to the abstracts of the resulting publications. Selected literature was then reviewed in its entirety for suitability. The inclusion criteria were as follows: studies of patients with advanced, incurable cancers, assessment of survival and quality of life (QOL) present, information about outcomes provided, information about patient or physician decision making given, published in English. No time-period limit was applied. Studies were excluded if they did not include information about outcomes, QOL, or patient decision-making. <xref ref-type="fig" rid="fig1">Figure 1</xref> summarizes the Prisma diagram for this review.</p></sec><sec id="s3"><title>3.

Judicious administration of chemotherapy with palliative intent has the potential to provide symptom reduction via decrease or stabilization of the tumor burden [<xref ref-type="bibr" rid="scirp.114797-ref4">4</xref>]. However, along with the improvement in tumor-related symptoms, anti-cancer medications are associated with often severe adverse effects.

Fatigue, anorexia, hair loss, peripheral neuropathy, nausea, and vomiting are just a few of the most common.

Honest discussions about poor prognosis are difficult and made more complex when attempting to incorporate all these elements. The inability to relay unfavorable prognostic information relates in part to inherent prognostic uncertainty [<xref ref-type="bibr" rid="scirp.114797-ref67">67</xref>].

A substantial fraction was either re-hospitalized or died within one month [<xref ref-type="bibr" rid="scirp.114797-ref102">102</xref>]. The decline in referrals from inpatient oncology to hospice and increased placements in subacute rehabilitation units seem to represent missed opportunities to explore and honor patients’ goals and values for a hope that materializes in only a minority of cases.</p><p>Physicians fear that they will be perceived as giving up if they talk about dying, thereby eliminating hope and depressing patients [<xref ref-type="bibr" rid="scirp.114797-ref103">103</xref>].

In fact, prediction of life expectancy is accurate in only 30% - 40% of cases [<xref ref-type="bibr" rid="scirp.114797-ref94">94</xref>]. Physicians give the least honest figures to those with the worst prognosis [<xref ref-type="bibr" rid="scirp.114797-ref26">26</xref>].

Conversely decisions may be complicated by the oncologists’ anecdotal experience of the occasional patient who seemed to respond to late-line chemotherapy [<xref ref-type="bibr" rid="scirp.114797-ref31">31</xref>].

These conversations must reflect both reasonable standards of good medical practice and goals that medicine can reasonably hope to achieve. Institutional culture can also play a role in physician decision-making at the end-of-life.

Dealing with and speaking about death regularly is a difficult task [<xref ref-type="bibr" rid="scirp.114797-ref120">120</xref>]. Oncologists may do so more often than other physicians and perhaps have a heightened desire to keep their patients around longer.

Disparities in Oncology Care at the End-of-Life</title><p>As more attention is rightly being paid to the structural racism that exists in healthcare, it is crucial for physicians to examine their unconscious biases that may play a role in determining which patients are offered further treatment at end-of-life and which are not. There have been analyses of disparities in upfront therapy such as surgical interventions leading to differences in survival [<xref ref-type="bibr" rid="scirp.114797-ref125">125</xref>].

Mullins et al. found that Non-White women with ovarian cancer were more likely to receive aggressive end-of-life care and non-Hispanic Black women were more likely to have Emergency Department visits and undergo procedures near end-of-life as compared with non-Hispanic White women [<xref ref-type="bibr" rid="scirp.114797-ref127">127</xref>].

In addition to addressing these issues at the systemic level through means such as advocating for a more diverse oncology workforce, is crucial that as individual providers, we examine our own implicit biases and strive for equity in when, how, and for whom we are deciding to stop chemotherapy [<xref ref-type="bibr" rid="scirp.114797-ref132">132</xref>].</p></sec><sec id="s8"><title>8.

The cessation of futile therapy is justified, for they burden the patient in the absence of benefit. Futile therapy is defined as contrary to justice because it does not represent a just allocation of resources. Oncologists must be prepared to tell their patient when they’d be better off without another line of treatment, even if this means initiating an end-of-life discussion [<xref ref-type="bibr" rid="scirp.114797-ref31">31</xref>]. This may be framed as discussing burdens and benefits of treatments, ideally as one would do all throughout the disease trajectory, so this framing is familiar to patients. Such end-of-life discussions are associated with less aggressive medical care near death and earlier hospice referral [<xref ref-type="bibr" rid="scirp.114797-ref34">34</xref>]. These discussions are also associated with lower rates of ventilation, resuscitation, or ICU admission, longer hospice stay and better QOL [<xref ref-type="bibr" rid="scirp.114797-ref83">83</xref>]. Only 37% of patients report having end-of-life discussions with providers. End-of-life discussion should take place in a quiet, comfortable, private location with adequate uninterrupted time [<xref ref-type="bibr" rid="scirp.114797-ref136">136</xref>]. Oncologists may use the frame that at this point in the patient’s disease progression, the burdens of a treatment outweigh the benefits, and as such it makes sense to shift focus onto what can be done at end-of-life rather than focusing on what is being taken away. This involves an exploration of a patient’s goals and values considering recommendations for aggressive comfort-focused care.</p><p>Also, events considered likely to occur given the clinical condition and what may happen with withholding treatment should be discussed [<xref ref-type="bibr" rid="scirp.114797-ref137">137</xref>] [<xref ref-type="bibr" rid="scirp.114797-ref138">138</xref>].

Good symptom management is critical to improving QOL in patients with advanced cancer.

Delays in referral to palliative care services causes difficult integration between primary anticancer care and supportive/palliative care [<xref ref-type="bibr" rid="scirp.114797-ref134">134</xref>]. Learning that patients who received early palliative care had prolonged survival may be reassuring to patients and providers of health care [<xref ref-type="bibr" rid="scirp.114797-ref145">145</xref>]. Patient’s receiving early palliative care also have half the odds of receiving chemotherapy within 60 days of death, longer interval between last dose of intravenous chemotherapy and death, and higher enrollment in hospice care for longer than one week [<xref ref-type="bibr" rid="scirp.114797-ref146">146</xref>]. The literature not only suggests that patients receiving palliative care may live longer, but their QOL is also improved [<xref ref-type="bibr" rid="scirp.114797-ref147">147</xref>] [<xref ref-type="bibr" rid="scirp.114797-ref148">148</xref>]. Patients spend less of their time at the end-of-life in hospital or focused on medical treatments. Additionally, chemotherapy administration near time of death may delay or prevent access to hospice services, because hospice agencies in the United States often lack funds to pay for chemotherapy or recurrent hospital stays [<xref ref-type="bibr" rid="scirp.114797-ref34">34</xref>]. Of note, half of bereaved family members felt that timing of referrals to palliative care for their loved ones was too late [<xref ref-type="bibr" rid="scirp.114797-ref149">149</xref>].</p><p>Lastly, physicians must remember to address patients’ spiritual needs as well. Spirituality and religiosity are well recognized as factors that affect patient QOL, quality of care, and satisfaction. Most patients report that these two items help them cope with their cancer and prognosis as well as serve as a source of strength and comfort [<xref ref-type="bibr" rid="scirp.114797-ref150">150</xref>]. The Coping with Cancer study showed that 60% of patients reported their spiritual needs were minimally or not at all supported by the medical system and those whose needs were met had threefold greater odds of receiving hospice care and less likely to receive aggressive care [<xref ref-type="bibr" rid="scirp.114797-ref98">98</xref>]. Studies have suggested that greater attention to spiritual beliefs can foster a negotiated and mutually acceptable plan of care [<xref ref-type="bibr" rid="scirp.114797-ref151">151</xref>].</p></sec><sec id="s9"><title>9.

Patients may ask again about chemotherapy and framing in terms of the burdens outweighing the benefits may be useful.</p><p>6) Consider consulting palliative care teams even before having these conversations (integrated with usual oncology care).</p><p>7) When introducing palliative care or hospice, frame them in terms of what services may be provided or symptoms addressed, rather than in terms of taking things away or because “there’s nothing left to offer.” Instead: “It sounds like pain has been a challenge and coming into the clinic for me to assess it takes up a lot of your energy. One thing that may help is having a team that comes to your house to help with medications instead.

Conclusion</title><p>It is imperative that cancer care providers appreciate the profound anxiety experienced at the junction between life and death. Currently, patients and their families are most in need of honesty, kindness, and engagement [<xref ref-type="bibr" rid="scirp.114797-ref147">147</xref>] [<xref ref-type="bibr" rid="scirp.114797-ref148">148</xref>]. The decision to cease chemotherapy is one that should be approached with careful consideration and accurate information. It is perhaps the most significant, empowering, and terrifying turning point in a patient’s journey. An honest, intimate, and collaborative patient-physician relationship is key during this time. For when all barriers are acknowledged and overcome, personal connections between the patient and the healthcare will determine the solution to the question “what next?”.</p></sec><sec id="s11"><title>Conflicts of Interest</title><p>The authors declare no conflicts of interest regarding the publication of this paper.</p></sec><sec id="s12"><title>Cite this paper</title><p>Staples, J., Mazina, V., Daubman, B.-R. and Goodman, A.
