Anesthesia Care for Cancer Patients

Cancer affects individuals across all age groups, with epidemiological data indicating a steady rise in the global cancer burden—a trend that closely parallels population growth and aging. As a substantial proportion of cancer patients will require surgical intervention during the course of their disease, this increasing incidence has led to a corresponding surge in demand for cancer-related surgical procedures worldwide. This chapter aims to contextualize the expanding role of oncoanesthesia within the framework of multidisciplinary cancer care, highlighting its influence not only on perioperative outcomes but also on long-term survivorship. To deliver optimal care, healthcare professionals involved in the perioperative management of oncology patients must possess a comprehensive understanding of evolving demographic trends, cancer epidemiology, tumor biology, and the perioperative implications of emerging oncologic therapies. As cancer care continues to evolve, anesthesiologists are increasingly recognized as integral contributors to improving both immediate and longterm outcomes in this growing patient population.

The perioperative management of cancer patients is complex due to cancerrelated physiological alterations and treatment-induced toxicities, requiring tailored anesthetic strategies. Malignancies and therapies like chemotherapy and radiation cause multisystem organ dysfunction, impacting cardiovascular, pulmonary, gastrointestinal, hepatic, renal, and hematologic systems. Surgical stress responses, including catecholamine release and immunosuppression, may promote metastasis. Anesthetic choices, such as total intravenous anesthesia (TIVA) and regional techniques, may mitigate immunosuppression and reduce recurrence risks compared to volatile agents. Preoperative evaluation must address organ-specific toxicities, such as anthracyclineinduced cardiotoxicity, bleomycin-associated pulmonary damage, and platinum-based nephrotoxicity. Intraoperative management involves advanced hemodynamic monitoring, lung-protective ventilation, and coagulation management. Postoperative care focuses on early mobilization, multimodal analgesia, and the prevention of complications. Special considerations include tumor lysis syndrome, endocrine paraneoplastic syndromes, and neurotoxicity from chemotherapy. A multidisciplinary approach integrating oncologists, surgeons, and anesthesiologists is essential to optimize outcomes. Prospective studies are needed to validate the impact of anesthetic techniques on long-term oncologic results.

This chapter explores the relationship between chemotherapy and anesthesia, highlighting the challenges faced in perioperative management of cancer patients. As chemotherapy remains a cornerstone of modern oncologic therapy, its systemic toxicities—including cardiotoxicity, neurotoxicity, hepatotoxicity, nephrotoxicity, and myelosuppression—present unique anesthetic considerations. The chapter systematically reviews major chemotherapeutic drug classes, including alkylating agents, antimetabolites, plant alkaloids, anti-tumor antibiotics, hormonal therapies, and biological response modifiers, alongside their mechanisms, indications, and adverse effects. Common malignancies, such as breast, colorectal, brain, and lung cancers—are discussed in detail to demonstrate how chemotherapy impacts anesthesia choices and perioperative planning. Strategies such as regional anesthesia, preoperative organ function assessment, and individualized anesthetic approaches are emphasized to mitigate risk. The chapter underscores the importance of multidisciplinary collaboration between oncologists, anesthesiologists, and surgeons to optimize outcomes and safety in the evolving field of oncologic surgery.

This chapter provides an overview of cancer immunotherapy, tracing its evolution from historical observations to cutting-edge therapies like immune checkpoint inhibitors, CAR T-cell therapy, and bispecific T-cell engagers. We explain how these treatments harness or modify the immune system to target cancer, detailing their mechanisms, clinical applications, and associated toxicities across multiple organ systems. Key agents include CTLA-4 and PD-1/PD-L1 inhibitors, high-dose IL-2, interferons, and therapeutic vaccines like Sipuleucel-T. As these drugs can potentially impact every organ system, thoughtful anesthetic planning for the care of cancer patients is critical for minimizing complications. We emphasize the importance of assessing immune-related adverse events (irAEs) such as pneumonitis, myocarditis, neurotoxicity, and endocrinopathies through preoperative planning and throughout the perioperative period. We advocate for close coordination with oncology and surgical teams to optimize perioperative care. Emerging therapies and future directions—including novel checkpoint inhibitors, CAR-NK cells, and oncolytic viruses—are also discussed, highlighting the field's rapid growth and evolving clinical impact.

This chapter will provide an in-depth review of radiation therapy and its implications on anesthetic management. It will begin with a brief overview of cancer and the history of radiation therapy’s progression into an essential tool in cancer treatment. Next, the mechanism behind radiation therapy’s effectiveness in targeting cancer cells will be explored. Lastly, a systems-based approach to radiation therapy and its impact on anesthetic planning will be discussed.

The aim of this chapter is to explore the effects of perioperative anesthetic choices on cancer biology and recurrence. By looking at current research, this chapter compares how different anesthetic agents can affect immune function, inflammatory processes, and tumor progression. This chapter compares the effects of intravenous and volatile anesthetics, as well as the effects of commonly used analgesics. The goal of this chapter is to equip clinicians with basic knowledge on these effects to guide the creation of tailored anesthetic strategies in this relatively large patient population. This chapter also emphasizes the need for further research on these effects due to the relative lack of randomized controlled trials.

The population of cancer patients and the procedures they undergo have been increasing over the years. Knowing how cancer affects patients is important for perioperative anesthetic management. This chapter will describe the importance of the preoperative evaluation of cancer patients and their perioperative implications. Besides their primary cancers, these patients often have comorbidities, treatment regimens, and side effects that can affect the anesthetic plan. This chapter will explore the different organ systems affected by cancer and the perioperative considerations for the anesthesia provider.

In this chapter, we examine how unique situations arise in cancer patients and how they affect anesthetic management. The conditions include septic and obese patients, cancer-causing paraneoplastic syndromes such as Cushing’s and Lambert- Eaton Syndromes or tumor compression causing mesenteric ischemia. Finally, we examine anesthetic options for patients undergoing stem cell transplantation.

Postoperative management of cancer patients demands a nuanced and collaborative approach, extending beyond the operating room to ensure optimal outcomes. Anesthesiologists play a pivotal role in managing pain, minimizing complications, and supporting early recovery and rehabilitation. This chapter explores evidence-based strategies, including Enhanced Recovery After Surgery (ERAS), multimodal analgesia, and regional anesthesia techniques. It also highlights the importance of psychological support, nutritional optimization, complication prevention, and long-term pain and palliative care. The chapter highlights the anesthesiologist's unique position to lead multidisciplinary teams in delivering comprehensive, patientcentered postoperative care for oncology patients.

Children with cancer have a number of pre- and perioperative risk modifiers when they undergo surgical procedures. These can be a direct result of their pathology or treatment and can persist for years after the completion of therapy. In this chapter, we explore the various sequelae of the most common pediatric malignancies and the anesthetic considerations required to deliver optimum care to this vulnerable population.

Advances in both detection and management strategies have improved survival rates among cancer patients. As a result, more patients may benefit from ICU admission over the course of their disease. Considerations for admission to ICU should include both the short- and long-term prognoses as well as the reversibility of the acute illness. Cancer patients may be admitted to the ICU for a host of reasons, which may be due to the underlying malignancy, treatment related effects, or non-oncologic acute illnesses. Regardless of the indication for admission, these patients require complex coordination of care and a thoughtful and methodical approach to their ICU management. 

In this chapter, we will look at the anesthetic considerations and techniques that facilitate the safe and successful operative care of thoracic and neurologic tumors. Modality and drug choice will be discussed in both the context of hemodynamic stability and tumor effects. Additionally, airway management, vascular access, and invasive monitoring may change based on tumor type and location, along with patient presentation. The goal of this chapter is to provide the non-fellowship-trained anesthesiologist with a basic understanding of how to safely care for patients undergoing care that they may not commonly provide.

This chapter discusses the anesthetic management of major cancer surgeries involving the breast, female reproductive organs, prostate, testicle, and kidney. The focus will begin in the pre-operative area, addressing concerns for these patients prior to surgery. It will then explore the intraoperative anesthetic management of female and male cancers and their related surgeries. Finally, the chapter will examine the postoperative management of these patients.

Major oncologic surgeries present unique challenges for anesthesiologists, requiring a deep understanding of the pathophysiology of malignancy, the physiological impact of extensive surgical procedures, and the complexities of perioperative care. The anesthetic management involves a multidisciplinary approach between the surgical team and anesthesia providers. Methodical planning and advanced techniques can lead to optimal management of patients.
