single-lumen, but there are others with two lumens for separate administration of incompatible drugs. e connection between the catheter and the port can either be sealed during manu­facture or made at the time of placement. Most ports are now validated for high-pressure injection of contrast agent with a maximum pressure of 300psi, which corresponds to ow rates of up to 5mL/s.
30
Indications
e main indications for port insertion is cytotoxic chemother­apy for solid tumors and long-term antibiotic chemotherapy (e.g., cystic brosis), whereas externalized catheters are used in hematologic diseases and long-term parenteral nutrition. Blood sampling is possible with ports provided copious ush­ing is completed aer sampling.
Preoperative assessment
Platelet count should be more than 50,000/mm3, white cells more than 1,000/mm3 and international normalized ratio less than 1.5. A preoperative chest radiograph is not mandatory but is useful in cases of lung cancer, lymphoma, and ear, nose, and throat (ENT) tumors. In such cases and when a mediasti­nal invasion, compression, or thrombosis is suspected, a chest computed tomography (CT) scan is necessary to verify the absence of superior vena cava occlusion or partial thrombosis.
Vitamin K antagonists should be replaced by

low-molecular-weight heparin (LMWH). Areduced dose of LMWH should be administered the day before implantation and none the morning of the implantation. Subcutaneous fon­daparinux and new oral anticoagulants (rivaroxaban, dabi­gatran, apixaban) should be stopped 2days before implantation or even earlier in patients with renal failure. When possible, antiplatelet therapies should be discontinued and replaced by low-dose aspirin 5days before implantation, except in patients with recent coronary or arterial stenting. ere is no need to stop aspirin or non-steroid anti-inammatorydrugs.
Accessroute
Ultrasound imaging and real-time guidance are the stand­ard for port placement.31 In our institution 2,000 indwelling catheters and ports are implanted each year under ultrasound guidance. e distribution of central venous access is as fol­lows: 30% access of the internal jugular vein, 50% access of the brachiocephalic vein via a supraclavicular approach, 15% access of the axillary or subclavian vein via an infraclavicular approach, and 5% access of the femoralvein.
Figure 28.5 Ultrasound-guided infraclavicular access of the subclavian vein
with the needle “in plane.”
Percutaneous subclavian access was the rst described. Access to the subclavian vein is usually easy and rapid because there are reliable anatomical marks, especially the bones. It can be approached by an infra- or supraclavicular route. When anatomical landmarks are used, there is a non-reducible incidence of pneumothoraces (1–5%) and a risk of compres­sion between the clavicle and rst rib (pinch-o syndrome) concerning long-term catheters inserted via the infraclav­icular route. Pinch-o syndrome occurs in 1% of cases and may lead to fracture of the catheter (Figure 28.4) and the
embolization of a fragment in the cardiac chambers or the pul­monary arteries.
32,33
For these reasons subclavian infraclavicu­lar access using anatomical landmarks is not the best route for long-term central venous catheters and should be replaced by ultrasound-guided infraclavicular access of the axillary/sub­clavian vein (Figure28.5) or by ultrasound-guided supraclav­icular access of the brachiocephalic vein (Figure28.6).
e percutanous access of the internal jugular vein has
gained popularity because of the absence of pneumothoraces

e brachial and forearm veins may be used for central ven-
and pinch-o syndrome. e relatively high rate of inadvertent carotid puncture becomes irrelevant (incidence close to zero) when using ultrasound guidance.
34,35
e right internal jugular vein is in direct line with the superior vena cava and the right auricle and is ideally suited for long-term access. On the other hand, the aesthetic aspect is not always perfect because the catheter is sometimes clearly visible around the neck area. For aesthetic reasons, the best approach for jugular vein catheter­ization is probably a low and posterior approach behind the cla­vicular head of the sternocleidomastoid muscle (Figure28.7).
e external jugular vein is not used very oen because its junction with the brachiocephalic trunk is sometimes acute and will not always allow passage of the catheter.
e cutdown approach of the cephalic vein is oen used by surgeons. Here, an aesthetic advantage is evident, particularly in women, but it also has some disadvantages, such as 5–10% failure, because the vein is either too small or sinuous to be catheterized,36 thereby causing more venous thromboses than when using the other methods.
ous access, either via a cutdown or through a percutaneous vein puncture guided by venography or ultrasound.
37
e percutaneous access of the femoral vein has specic indications, such as mediastinal compression or invasion of the superior vena cava in lung cancer or lymphoma (Figure28.8), superior vena cava thrombosis (Figure 28.9), impossibility to puncture neck or chest veins due to local tumor invasion, infection, and postradiation therapy stenosis. Provided that the technique is well applied and the tip is close to the right atrium, infectious and thrombotic complications are compar­able to those seen aer subclavian or jugular access.
38,39
Because of the frequency of lung cancer and mediastinal localizations of lymphoma, femoral access should represent around 5% of all implanted ports. e port can be implanted at the outer side of the thigh or on the abdominal wall (Figure28.10).
Catheter tip location
All recent studies have shown that the position of the tip of central venous devices is a signicant factor for predicting

of Chest Physicians and French multidisciplinary cancer net­work are that the optimal tip position for central venous cath­eters and ports is the distal third of the superior vena cava or the proximal right atrium (Figure28.11).

ops in 2.4% of patients when ultrasound guidance is used for central venous access.44 e presence of mediastinal lymph nodes has been shown to be a risk factor for catheter-related venous thrombosis,45 and one should carefully examine the chest CT scan before implanting a central venous device in patients suering from lung cancer, lymphoma, and other dis­eases, including advanced ENT or thyroid cancer, for exam­ple. Patients with catheters that are too short, gastrointestinal cancers, or extensive metastatic disease have a higher risk of deep-vein thrombosis aswell.
For patients with catheter-related deep-vein thrombosis and cancer, treatment with LMWH for at least 3–6 months is recommended.
42,43
If the tip of the catheter is in the correct location and the port is functioning well, it is possible to keep it in place and to avoid retrievingit.
Recent studies have failed to show any benet from proph­ylaxis with warfarin or LMWH compared to placebo for the prevention of catheter-related thrombosis.
46,47
Based on these ndings, the American College of Chest Physicians Conference on Antithrombotic and rombolytic erapy and the French working group both suggested that the risk of clinically impor­tant catheter-related venous thrombosis may be too low to war­rant routine prophylaxis and has recommended that clinicians do not routinely use prophylaxis in cancer patients.
42,43

Catheter-related infection

Minor temporary local infections should be treated with local antiseptics and possibly oral antibiotics. Nevertheless, the port should be explanted where there is local swelling or purulent drainage.
Systemic infection is dened as fever, chills, and a positive blood culture. Methods of diagnosing catheter-related infec­tion without removing the catheter consist of comparison of

catheter dysfunction and catheter-related venous throm­bosis. When the tip is located in the last third of the superior vena cava or the right atrium, the rate of venous thrombosis is between 3% and 5%, compared with 42–46% when the tip lies in the proximal third of the vena cava or in the brachio­cephalic veins.

paired blood cultures drawn simultaneously via the port and from a peripheral venous site. Quantitative blood cultures or measurement of dierential time to germ growth are used for this purpose.
48,49
Aer a port infection has been proved, the port should be removed in the presence of severe neutropenia or septic shock, or when Staphylococcus aureus, Pseudomonas, Stenotrophomonas, or Candida species are isolated from blood culture. Parenteral then oral antibiotic therapy should be pre­scribed for at least 10days in case of bacteremia. Antibiotic-lock technique without removing the port is a possible alternative

Local antibiotic locks consist of 2 mL of highly concentrated amikacin or vancomycin (5mg/mL) that are changed every day for at least 10days, aer which blood cultures should be performed a few days aer the end of the treatment to conrm the success or the failure of this treatment.

Overview of palliativecare
e World Health Organization denes palliative care as an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness, through the prevention and relief of suering by means of early identication and impeccable assessment and treat­ment of pain and other problems, physical, psychosocial, and spiritual.1 Palliative care is focused on symptom relief and maximizing function, without necessarily impacting the nat­ural history of the underlying illness. Bereavement support is integral to its mission as it views the patient and his or her loved ones as a unit of care. Palliative care is interdisciplinary, involving not only nurses and physicians, but chaplains, psy­chologists, social workers, and speech, physical, occupational, and other therapists. While palliative care has historic roots in the terminal care of cancer patients, its scope encompasses a wide variety of patients with non-malignant diseases. ese include neurodegenerative disorders; advanced organ disease; and patients in critical care units.
2,3
Ideally, palliative care is provided to patients with severe illnesses early in the course of their disease, alongside disease-modifying or curative therapy. As an illness progresses, and as disease-modifying or even life-prolonging interventions become less available, a patient’s entire care may become palliative-focused. While much of the care of patients with life-threatening illness can be described as palliative, many patients will not require specialist palliative care, and basic competency in palliative care is important for clinicians across a variety of specialties and practice types.
4
Palliative medicine describes the physician’s role in the aforementioned care model. Besides expert symptom assess­ment and treatment, palliative medicine physicians oer subspecialty expertise in determining prognosis and commu­nication encounters with patients and families involving break­ing bad news, establishing goals of medical care, and planning for the future in light of a life-threatening illness. e scope of practice of palliative medicine physicians varies by location and institution. Common settings include inpatient consultative
increasing by number of programs and prevalence among adult and pediatric hospitals such that many cancer care providers will have access to palliative care specialists if needed.
5,6
ere are many benets when specialist palliative care is added to a patient’s treatment plan. Patients with life-threatening illnesses oen experience pain, fatigue, nau­sea, constipation, and dyspnea. Palliative care providers are trained to evaluate and treat these distressing symptoms and to escalate and/or transition medications as needed. In addi­tion to physical complaints, palliative care also improves other domains of life for patients and families. One study showed improved quality of life, less aggressive care at the end of life, earlier referral to hospice, and longer length of stay in hos­pice for those enrolled in early palliative care. is same study showed prolonged survival in patients receiving palliative care.7 Further, families report enhanced care for their loved ones and better access to bereavement care when palliative specialists were consulted.8 Palliative care involvement has been associated with improvement in several symptom-based quality measures as well, including decreased Intensive Care Unit length of stay9; reduction in hospital costs
10,11
; reduction in readmission rates12; and reduced utilization of Emergency Department services.

Overview of hospicecare
Hospice care is related but distinct from palliative care. eir underlying philosophies and interdisciplinary approach to care are identical. Hospice, however, has a distinct model of care and reimbursement system that is largely dened by the Medicare Hospice Benet (MHB) in the USA. Medicaid and private insurers generally provide similar benets. e MHB requires physician certication that a patient has an expected progno­sis of 6months or less if the disease runs its expected course. Patients can continue to receive hospice care beyond 6months as long as their anticipated life expectancy remains less than 6 months. e vast majority of hospice care is provided in patients’ homes or is provided to patients within long-term care

Who provides the care Medical specialty of physicians and nurses; many
programs will also have support of psychology, social work, chaplain
facilities where the facility is considered the patient’s “home.” e MHB provides payment for skilled nursing, home health aides, and volunteer visits; durable medical equipment and medications related to the terminal diagnosis; respite care; physical and occupational therapy; social work and chaplaincy services; and bereavement follow-up.
6,14
Medicare-certied hospice agencies must be able to provide acute, inpatient-level care for severe symptom control or imminent death; the MHB does not cover room and board fees for long-term care facili­ties, including residential hospices (Table29.1).
Communication with cancer patients
Cancer is oen a terrifying diagnosis and cancer treatments are oen dicult to understand. In fact, it has been shown that many advanced cancer patients do not understand that their cancer is incurable, or that their treatment is not intended to cure them.
7,15
Strong emotions and intrafamily conicts are common, making communication about important issues challenging. is section will highlight important elements of communication with cancer patients.
Prognostication
For patients with advanced cancer, goals of care discussions can be particularly challenging. e rst step is for the clini­cian to establish a prognosis based on current best evidence. Prognostication in advanced cancer, as with any illness, is inex­act; however, a substantial amount of research is available for guidance. For cancers that are not advanced, disease-specic factors such as the type of cancer, its stage and histologic grade, and early responses to chemotherapy are important for deter­mining a broad prognostic range. As cancer progresses, how­ever, patient factors, particularly functional status, become more important for prognostication.
Functional status, also known as performance status, is a global measure of a patient’s mobility and ability to care for him- or herself. As a patient becomes more debilitated from her or his advancing cancer, performance status and length of survival diminish. e Karnofsky Performance Status (KPS) is a reliable and widely used scale to measure functional

status.
It rates a patient’s functional status from 0 (dead) to 100 (no disease-related symptoms) (Table29.2). Prognosis with the KPS has been studied across multiple cohorts of ter­minally ill cancer patients, with overall consistent results.
Patients with metastatic cancer and a KPS of 40 have a median life expectancy of approximately 2–3 months; expected sur­vival decreases rapidly with poorer performance status. Agood way to assess performance status is to ask the patient how much of the day she or he spends in bed or in a chair; greater than 50% of the day indicates substantial disability and a prognosis of less than 3months for most patients. Functional status is also strongly correlated with survival in patients in phase Ichemotherapy trials.
Other factors that inuence prognosis include age and symptom burden. Younger individuals tend to decline less quickly than the elderly, although this protective eect is lost as disability progresses.21 e onset of certain symptoms in advanced cancer portends a worse prognosis. Cognitive impairment, xerostomia, dysphagia, anorexia and weight loss, and dyspnea, have all been individually and independently associated with a decreased survival. vival is only 1–2months aer the onset of hypercalcemia of malignancy, except for tumors which readily respond to treat­ment such as breast cancer or myeloma. with untreated brain metastases is 1 month; it improves to 3–6months with treatment.
Considering that clinicians do not always perform an accu­rate assessment of functional status on each clinical encounter, the Glasgow Prognostic Score (GPS) is an additional validated prognostic tool which takes into account serum C-reactive protein (CRP) and albumin as a marker of systemic inamma­tion. Ahigher GPS score (elevated CRP and low albumin) has been reliably shown to predict poor survival in patients with many dierent types of cancer.
Despite readily available prognostic indices and criteria, physicians are generally poor prognosticators. ies have shown that physicians oen overestimate prognosis of terminally ill cancer patients by a factor of three to ve. addition, physicians oen deliberately disclose an overly opti­mistic prognosis to terminally ill cancer patients,,33 usually in an attempt to avoid emotional harm to a patient.
Although there is a large amount of heterogeneity in patients’ reports of what they want to know from prognostic disclosures, in general, patients want honest, straightforward information presented compassionately. recommended to give accurate but general ranges, such as “days to weeks,” “weeks to short months,” or “months to years”.36 It is

also important to share prognostic uncertainty with patients, preparing them for the worst while hoping for the best. An example would be saying:“Because of all the things we have spoken about, Iam worried that you may have only weeks to a few months to live. It is important for you to know that doctors are oen wrong when we predict time. Some people live longer that we think they will and some people live a lot shorter than we predict. Ido not know what will happen in yourcase.”
In a sense, prognostic disclosures can be viewed as any other medical intervention, presenting a balance of risks and benets. Risks include emotional harm to a patient and its con­sequences. Potential benets include allowing patients to make appropriate future plans, to identify life priorities, and to more fully weigh burdens and benets of future medical care in light of their prognosis.
Breaking badnews
Breaking bad news is emotionally dicult for patients and clinicians. No approach to breaking bad news can amelior­ate the psychic impact on a patient or a family of life-altering news about one’s health. However, certain approaches can be utilized to reduce harm. In general patients want informa­tion oered in an honest and simple manner, for a loved one to be present, and for there to be ample time for questions.35 It can be helpful to consider four elements or steps to break­ing bad news: preparation, content, patient’s response, and summary (Table 29.3).
19,37,38
In preparation, it is helpful to arrange a quiet environment with minimal chance of inter­ruption. Additionally, it is important to be prepared for ques­tions regarding the patient’s past care, prognosis, and treatment options. Prior to delivering bad news it is recommended to ask the patient what she or he understands about her or his disease, treatment, what she or he foresees in the future, and what the patient wants to know. is way the clinician can establish how much and what sort of information she or he needs toshare.

Prior to delivering the content of the bad news, many experts suggest that clinicians issue a warning that bad news is forth­coming. Next, the news should be delivered in straightforward language which avoids medical terminology and complicated statistics. If a patient wants detailed medical explanations he or she will generally tell you. If it is believed the patient is dying, and especially if the patient’s knowledge of this is important for planning appropriate future care, the word “dying” should be stated explicitly. For example, one might say “You have received several chemoembolization treatments for your liver cancer. e rst one seemed to help you– the cancer shrunk and you felt better for a while. However, aer the last two treatments the cancer didn’t shrink and you have been getting sicker, and are now so weak that you are spending most of the day on the couch. Because of this, unfortunately, more treatments aren’t going to help you live longer or feel better. Iwish it wasn’t this way, but you are dying from the cancer.”
Aer delivering the bad news it is important to stop and allow the patient and family to respond, even if there is a period of silence. Patients may express grief, despair, anger, guilt, or other strong emotions. Some patients may express relief at knowing what is going on. Regardless, it is import­ant to empathetically acknowledge the patient’s emotions and to allow the patient time to present them before moving forward. e summary of the interaction will depend on the nature of the news. Patients and families will generally want to know what the news means for the future, such as the avail­ability and types of future treatments. If the bad news marks a distinct turn in the focus of a patient’s care from curative to non-curative, the patient’s own goals for the future should be assessed.39 One can ask, “In light of this information, I’d like to discuss what is important for you in the future, in regard to both your personal life and your future medical care.” is allows the patient opportunity to bring up personal, spiritual, and familial goals and concerns, as well as opening a discussion

patients a change in treatment focus can be quite traumatic. In this case it is important to stress that, despite this apparent change, the focus will continue to be providing the patient the best possible care, even if now aspects of that care are dierent.
Interventional oncologists are oen referred patients who have failed multiple prior medical and/or surgical treatments and have very advanced disease. Careful evaluations of patient performance status, patient and family goals and understand­ing of the disease, available treatment options, and risks and benets of treatment are required prior to recommending a treatment plan. For many of these patients, even minimally invasive interventional oncology treatments are not indicated and will only decrease their quality of life. Prospectively iden­tifying these patients can be challenging and patients and families will oen have unrealistic expectations. However, it is important to consider and discuss not performing any further interventional therapy as an option in patients with advanced disease.

Medical symptom management

Much of the clinical practice of symptom management for cancer patients is based on decades of clinical experience rather than well-controlled clinical trials. Despite this, expe­rience has shown that most cancer-related symptoms can be eectively treated to the point of an acceptable patient-dened quality of life. General principles of symptom management are listedbelow.
1. Consider a wide dierential diagnosis and pursue a
problem-focused evaluation. New or progressive symptoms
in the cancer patient most likely arise as direct eects of the
cancer, but medication side eects, medical comorbidities,
psychological processes, and paraneoplastic syndromes
may be additional etiologies of distress.
2. Reconsider a diagnosis if a symptom is not responding
or progressing as expected. Develop a treatment plan that
involves frequent assessment of the patient’s response to
therapy as well as any adverse eects. If the patient has an
inadequate response to a drug, consider either dose esca-
lation or addition or substitution of a second agent, pref-
erably one that modulates the symptom in a new way. An
example of this would be adding a serotonin antagonist to a
dopamine antagonist for refractory nausea.
3. Arrange close follow-up aer every change in the treatment
plan. Many cancer patients are elderly and should always be
screened for polypharmacy and drug–drug interactions.
4. Employ non-pharmacologic and complementary interven-
tions alongside pharmacological treatment.
5. Prompt referral of patients to specialist providers is recom-
mended when routine treatments fail to provide adequate
symptom relief. Palliative medicine physicians, pain spe-
cialists, and mental health professionals are available at
many institutions. is section will discuss the medical management of com-
mon symptoms cancer patients face, including pain, nausea,
Pain
At least one-third of cancer patients will experience pain while undergoing treatment, and at least three-quarters of end-stage cancer patients will experience signicant pain.40 e vast majority of patients’ pain can be eectively treated with consci­entious management.41 is section will review the evaluation and treatment of cancer pain, highlighting pain management approaches for bone metastases.
Pain is categorized as either nociceptive or neuropathic in origin. Nociceptive pain refers to pain generated by the aerent neural pathways which respond to tissue damage, whether from tumor inltration, infection, infarction, distension, or other unwelcome stimuli. It is divided into two subtypes: somatic and visceral. Somatic pain arises from the skin, muscles, bones, and connective tissues. Arthritic pain, fractures, and osseous metastases are common examples of somatic pain. It is usually described as dull, achy, and well localized.42 Visceral pain arises from the abdominal and thoracic organs and is oen described as deep, poorly localized, but sharp. It can be referred, such as shoulder pain referred from metastases causing liver capsular distension. When caused by distension of hollow organs such as bowel, gallbladder, or ureter, visceral pain is typically described as crampy or colicky. Neuropathic pain describes pain gener­ated by damaged or dysfunctional neural tissue within the cen­tral or peripheral nervous system. It can be localized to a single nerve or nerve root, as in a radiculopathy, or more diusely to distal nerve bers as in diabetic or chemotherapy-induced peripheral neuropathy. Neuropathic pain is described as burn­ing, shooting, or numb, and is oen associated with changes in pain perception, such as allodynia or hyperesthesia. It is estimated that approximately 40% of cancer patients with pain have a neuropathic component.42 Common scenarios include radicular pain from vertebral metastases impinging on nerves as they exit the spinal cord, chemotherapy-induced peripheral neuropathy, or herpes zoster infection (shingles).
Table29.4 outlines key features of a comprehensive pain
assessment. Necessary elements include a thorough physical examination and evaluation of the location and radiation of the pain; temporal aspects of the pain; its severity– typically meas­ured by one of several pain scales (e.g., zero to 10); pain quality (e.g., dull or sharp) to assess for somatic vs. visceral vs. neuro­pathic origin; aggravating and alleviating factors; and the use of medications and non-medical treatments and their eects. Particular attention should be paid to the limitations in func­tion brought about by the pain (e.g., with sleep, eating, move­ment, and mood). Finally, a thorough pain assessment includes discussion of social, psychological, and spiritual factors which may be contributing to or aected by the pain.
Consideration of a broad dierential diagnosis of new or worsening pain is recommended for the cancer patient, as not all pain is the direct result of tumor-associated tissue dam­age. For instance, back pain in a cancer patient may represent benign chronic or acute musculoskeletal back pain; vertebral metastases causing bony pain or compressing a nerve root
