Molecular oncology, as it relates to cancer formation, growth, metastasis, and treatment, is a rapidly progressing and exciting field. Its forward movement is so fast that even scientific journals, because of publication delays, are unable to keep readers informed in a timely manner. What, therefore, is the role of a textbook on molecular oncology?

The article by Hambleton provides a compendium of the causes of hematopoietic defects in HIV-infected individuals. For the busy practicing physician who treats patients with HIV, these defects are not trivial. Cytopenias are a continuous problem that impact on most clinical decisions. For example, anemia and neutropenia are more common in patients with 100 CD4 cells/mcL or less. In general, these patients also have the highest titers of virus and are at greatest risk of developing symptomatic Mycobacterium avium or cytomegalovirus infection. Thus, physicians often find themselves trying to decide which patients should undergo a more extensive evaluation and which should receive "less" myelosuppressive therapy.

For all the vast literature concerning survival after treatment for cancer, few articles provide long-term follow-up. At best, most provide 5-year survival statistics, the majority being actuarial, which means that many of the patients included do not even have 5-year follow-up. A few articles give 10-year data and call these long-term. But 5 or even 10 years is not a very long time for a child or young adult hoping for a normal life span, or for clinicians wishing to be able to predict a patient's prognosis after treatment.

Benign and aggressive intracranial meningiomas, as the authors state, are seemingly simple tumors (even with benign histology) that can behave in a clinically malignant fashion solely by location. Clinicians with experience in the management of patients with aggressive, recurrent, or malignant meningiomas are all too well aware of the difficulties of recommending effective therapy beyond surgery and radiation therapy. Clearly, there is much room for improvement in the treatment of recurrent or malignant meningiomas with local or systemic chemotherapy and/or biologic therapies.

Drs. Dresler and Goldberg review the role of resection of metastatic tumors to the lung. It is a difficult topic, with the exception of osteosarcoma, for which the practice of secondary resection is common and clearly of benefit. For lung metastases from other tumors, however, the use of resection is based largely on sporadic and anecdotal reports.

The diagnosis and treatment of children with brain tumors has changed radically over the last 50 years. Cross-sectional imaging, CT and MRI, has displaced angiography and pneumoencephalography. These newer imaging modalities have facilitated early diagnosis, preoperative planning, and surgical approach, resulting in an increased likelihood of achieving complete surgical extirpation. The operating microscope has improved the experienced surgeon's ability to discriminate between tumor and normal brain, making radical resection more frequent. Chemotherapy has been introduced into the arsenal of the neuro-oncologist, albeit with only modest success. The one nearly constant treatment modality has been external-beam irradiation.

Meningioma is a prime example of a tumor requiring a multimodality approach. This tumor is usually benign and often grows slowly. Under many circumstances, such a benign tumor would never attract the attention of the oncologist or even require treatment at all. However, a meningioma is a benign tumor in a malignant location. In the closed space of the skull, there is no room for expansion of even a benign lesion; thus, effective treatment of this potentially neurologically devastating lesion is necessary. Neurosurgeons, neuroradiologists, radiotherapists, and medical oncologists are all directly involved in treatment decisions. Rapidly expanding knowledge concerning the etiology and natural history of meningiomas may now also involve epidemiologists, molecular geneticists, and endocrinologists. Despite this concentration of expertise, numerous questions remain unanswered or incompletely answered.

The appearance of metastases is generally thought to herald widespread dissemination of a primary cancer. At this point, surgery usually is either not indicated or palliative. Thus, it is somewhat surprising that surgical resection of metastases has become an accepted treatment modality in several clinical situations. This is due, in part, to the unique biology of several types of cancers and to well-defined clinical presentations that can be identified. Drs. Dresler and Goldberg succinctly review the indications for and results of resection of pulmonary metastases.
