In the realm of oncology, the standard of care is a critical concept that underpins medical practice and malpractice litigation. For attorneys handling oncology malpractice cases, understanding the nuances of the standard of care is essential. This article will delve into what constitutes the standard of care in oncology, how it is determined, and the role of an expert medical oncologist in evaluating deviations from this standard.


What is the Standard of Care in Oncology?

The standard of care in oncology refers to the level and type of care that a reasonably competent and skilled health care professional, with a similar background and in the same medical community, would have provided under similar circumstances. It encompasses:

  • Diagnosis: Accurate and timely identification of cancer through appropriate use of diagnostic tools and tests.
  • Treatment: Administration of accepted therapeutic interventions, including surgery, chemotherapy, radiation therapy, and newer modalities like immunotherapy and targeted therapy.
  • Follow-Up: Regular monitoring of the patient’s progress, management of side effects, and adjustments to treatment as necessary.

Determining the Standard of Care

Several factors influence the determination of the standard of care in oncology:

  • Medical Guidelines: National and international guidelines, such as those from the National Comprehensive Cancer Network (NCCN) or American Society of Clinical Oncology (ASCO), provide benchmarks for standard care practices.
  • Peer Practices: What is commonly practiced by peers in the same field and geographical area. This is what most reasonable oncologist would do given similar circumstances. There may be more than one reasonable approach however some approaches can be definitively unreasonable.
  • Clinical Trials and Research: Latest findings from clinical research and trials that may set new standards for treatment. Often looking at the standard of care treatment arm of an ongoing randomized clinical trial can demonstrate current treatments hence the rationale to test “experimental” or “investigational” treatments against the standard of care.
  • Expert Consensus: Opinions and consensus among experienced oncology professionals. Occasionally, there are rare tumor types where the evidence of care is limited to case reports, case series and expert opinions at large institutions with a significant experience in treating the rare tumor type.

The Role of an Expert Medical Oncologist

In malpractice litigation, an expert medical oncologist plays a pivotal role in evaluating whether the standard of care was met. Here’s how:

  1. Reviewing Medical Records:
  • Comprehensive examination of patient records, including pathology reports, imaging studies, treatment protocols, and follow-up notes.
  • Identifying any lapses or deviations from accepted medical practices.
  1. Assessing Diagnostic Accuracy:
  • Determining if appropriate diagnostic tests were ordered and correctly interpreted.
  • Evaluating if the diagnosis was made in a timely manner, allowing for prompt treatment.
  1. Evaluating Treatment Decisions:
  • Assessing the suitability of the chosen treatment regimen based on the patient’s specific cancer type, stage, and overall health.
  • Checking for adherence to established guidelines and whether the treatment was administered correctly.
  • Discussion at a multi-disciplinary conference with consensus opinion is a strong evidence approach with multiple physicians in agreement with a stated diagnostic or treatment approach at the institution as opposed to one individual opinion managing a patient as a Lone Ranger.
  1. Monitoring and Follow-Up:
  • Ensuring that the patient’s progress was adequately monitored and documented.
  • Evaluating if any necessary adjustments to treatment were made promptly based on patient response.
  1. Providing Expert Testimony:
  • Offering clear, unbiased opinions during depositions and trials.
  • Explaining complex medical concepts in an understandable manner for the court.
  • It is always best to ensure both the retaining attorney and expert witness are on the same page regarding opinions and concept understanding.

Common Deviations from the Standard of Care in Oncology

Certain actions or omissions can constitute a deviation from the standard of care, including:

  • Delayed Diagnosis: Failure to recognize and diagnose cancer promptly, leading to progression of the disease.
  • Improper Treatment: Using outdated or inappropriate treatment protocols that do not align with current guidelines.
  • Inadequate Follow-Up: Not adequately monitoring the patient’s response to treatment or failing to address side effects and complications in a timely manner.

Importance for Attorneys

For malpractice attorneys, understanding the standard of care in oncology is crucial for several reasons:

  • Case Evaluation: Assessing the merits of a case based on whether the standard of care was breached.
  • Building a Strong Case: Leveraging expert testimony to establish a deviation from the standard of care and its impact on the patient.
  • Effective Cross-Examination: Challenging opposing expert witnesses by highlighting inconsistencies or deviations from established medical practices.

The standard of care in oncology is a cornerstone of medical practice and malpractice litigation. For attorneys, a deep understanding of this concept, coupled with insights from expert medical oncologists, is essential for effectively handling oncology malpractice cases. By comprehensively reviewing medical records, assessing diagnostic and treatment decisions, and providing clear expert testimony, an oncology expert can significantly bolster a legal case, ensuring that justice is served and medical standards are upheld.
