Challenge of supportive surgical care in pediatric oncology

Pediatric oncologic endosurgery

Despite increasing popularity of minimal-invasive techniques in the pediatric population, their use in diagnosis and management of pediatric malignancy is still debated. Moreover, there is limited evidence to clarify this controversy due to low incidence of each individual type of pediatric tumor, huge diversity of the disease entity, heterogeneity of surgical technique, and lack of well-designed studies on pediatric oncologic minimal-invasive surgery. However, a rapid development of medical instruments and technologies accelerated the current trend toward less invasive surgery, including oncologic endosurgery. The aim of this article is to review current literatures about the application of the minimal-invasive approach for pediatric tumors and to give an overview of the current status, indications, individual techniques, and future perspectives.

Central Line Placement for the Pediatric Oncology Patient: A Model of Advanced Practice Nurse Collaboration

Central lines are commonly placed in pediatric oncology patients during their therapy. Advanced practice nurses (APNs) play an important role in the coordination and facilitation of line placements so that they may be inserted in an expeditious manner. Collaboration between the Divisions of Oncology and Surgery is often key to attaining this goal. At the Children’s Hospital of Philadelphia, the APNs in Oncology and Surgery have developed a collaborative approach to the placement of central lines in oncology patients. Many positive changes ensued between these divisions after collaboration occurred and a system for line placements was put into place. A well-defined process for central line placement is currently being utilized that meets the needs of the patients. Central lines are being placed in a timelier manner, procedures are coordinated, and treatment is started earlier, which has increased the satisfaction of patients, families, and health care providers. Finally, this collaboration led to an improved relationship and better communication between the Divisions of Oncology and Surgery.

Lung nodules in pediatric oncology patients: a prediction rule for when to biopsy

PURPOSE

The purpose of the study was to develop a prediction rule regarding the factors that most accurately predict the diagnosis of a malignancy in a lung nodule in the pediatric oncology patient.

METHODS

A retrospective review of pediatric oncology patients that underwent lung nodule resection between 1998 and 2007 was performed. Multivariable logistic regression was used to create a prediction rule.

RESULTS

Fifty pediatric oncology patients underwent 21 thoracotomies and 48 thoracoscopies to resect discrete lung nodules seen on computed tomographic scans during workup for metastasis or routine surveillance. The mean nodule size was 10.43 ± 7.08 mm. The most significant predictors of malignancy in a nodule were peripheral location (odds ratio [OR], 9.1); size between 5 and 10 mm (OR, 2.78); location within the right lower lobe (OR, 2.43); and patients with osteosarcoma (OR, 10.8), Ewing sarcoma (OR, 3.05), or hepatocellular carcinoma (OR, 2.38).

CONCLUSIONS

Lesions that are between 5 and 10 mm in size and peripherally located in patients with osteosarcoma, Ewing sarcoma, or hepatocellular carcinoma are most likely to be malignant. Use of a prediction rule can help guide clinical practice by determining which patients should undergo surgical resection of lung nodules and which patients may be closely observed with continued radiologic studies.

Radical palliative surgery: new limits to pursue

This case report describes the radical subtotal palliative resection of a massive recurrent desmoid tumor encompassing the abdomen, pelvis, and groin in a child who was 13 years old at the time of initial resection. Given the extensive distribution of the tumor en bloc resection, which is the standard treatment of desmoid tumors, would have meant performing a hemipelvectomy and repair of a large abdominal wall defect, likely with skin grafts and mesh. The patient's personal goals however were to alleviate the pain and limited mobility that would allow her to re-attend high school and appear normal to her peers. Therefore, palliative surgery was pursued and currently the patient is 5 years out from her last surgery doing well. We believe that the option of surgical palliation in this case was warranted and should be an option for similar cases in the future.
