Cancer remains the second leading cause of death in the US after heart disease.1 However, patients with cancer have recently benefited from advancements in both diagnostic tools and therapies, which often extend both disease-free and overall survival. As a result, patients with solid and hematologic malignancies are living longer.
During the course of treatment or survivorship, oncology patients may require general surgical consultation for conditions that arise independent of their malignancy or as a consequence of their disease or therapy. In addition, general surgeons frequently are consulted for tissue diagnosis of suspected malignancies, vascular access, and long-term complications of oncologic surgery. Management of acute general surgery issues in this setting is challenging and often requires complex decision-making, which accounts for patients’ oncologic therapy and prognosis, as well as their surgical condition.
Concerns that are unique to cancer patients include neutropenia, concurrent systemic therapy, concerns about metastatic disease, and overall prognosis that further complicate the management of acute general surgical conditions.2,3
Approximately 10%−15% of adults in the US will develop gallstones, and 1%−4% will develop symptoms.4 In addition to the normal risk factors for acute cholecystitis, cancer patients may develop the condition because of biliary stasis secondary to liver metastases, malnutrition or rapid weight loss, and overall impaired immunity.
Integrating general surgeons in vascular access procedures can allow for a more timely initiation of systemic therapy and improved patient satisfaction by minimizing delays in treatment initiation or disruptions in therapy.
In a Danish population-based study, the relative risk for cholecystitis among patients with cancer compared with the general population was 1.38 (95% confidence interval, 1.20–1.58), with the highest risk of cholecystitis in the first 6 months after initial cancer diagnosis. In addition, the risk of cholecystitis was highest in cancer patients younger than 70 years of age and in patients with newly diagnosed pancreatic and colorectal cancers.5 Several meta-analyses and randomized trials have recommended early cholecystectomy in low-risk cancer patients.6 General surgeons not only provide expertise in these cases, but also offer continuity of care in patients who require percutaneous cholecystostomy tube placement and participate in decision-making about the need for interval cholecystectomy in the context of planned future therapies.7
Adequate vascular access is extremely important in the care of oncology patients during the initial phase of surgical treatment and chemotherapy, as well as in the long-term management of advanced cancer.8 Integrating general surgeons in vascular access procedures can allow for more timely initiation of systemic therapy and improved patient satisfaction by minimizing delays in treatment initiation or disruptions in therapy. When deciding on a location for vascular access, the site of malignancy and anticipated operative and radiation fields should be considered and, when possible, avoided.
For a new cancer diagnosis or evaluation for recurrence, biopsies are typically needed for tissue diagnosis and subsequent treatment planning. Malignancy is identified in 4% of patients older than age 40 who present with unexplained lymphadenopathy versus 0.4% of patients younger than 40 years old.9 In some cases, the history, physical exam, and imaging will identify the underlying etiology; however, biopsy still is necessary in most patients.
Although fine-needle aspiration and percutaneous image-guided biopsy have more than 85% sensitivity, general surgeons often are consulted for open excisional or incisional biopsies.10,11 These procedures provide a diagnostic option in patients who have inadequate tissue sampling with a percutaneous approach or who have lymph nodes inaccessible by less invasive techniques.
Other general surgery needs in the oncologic population may include:
Communication and coordination of care among general surgeons and the multidisciplinary oncology team is critical to ensure that active issues can be addressed effectively, while also considering the patient’s prognosis, current treatment, and future therapeutic options.
As survival improves for many cancers, the focus of patient care should also include quality of life. Ventral incisional hernias after laparotomy can cause pain and a poor cosmetic appearance, thereby reducing quality of life in cancer survivors. In the general population, 3%−20% of patients who undergo laparotomy develop ventral incisional hernias.12 The hernia rate increases to more than 40% in patients who undergo abdominal operations for cancer and more than 50% for patients who specifically undergo hepatic resection, pancreatectomy, laparoscopic or open colectomy, and esophagectomy.13 General surgeons are often consulted for their expertise in incisional, parastomal, and inguinal hernias during the survivorship period and can offer patients a significant improvement in quality of life in many cases.
Acute care general surgeons play a unique role in the surgical oncology population by providing a patient-centered and efficient approach to comprehensive cancer care. General surgeons offer continuity of care for nononcologic surgical diseases and provide specific expertise on general surgery conditions, which may help provide safe and effective care for cancer patients. Moreover, general surgeons can help reduce wait times for nononcologic surgical issues such as vascular access.
