After pegylated liposomal doxorubicin (PEG-LD) (Doxil) was shown to be active in ovarian tumors, several trials were developed at the University of Southern California to determine its safety and efficacy in a variety of gynecologic and peritoneal malignancies. Completed phase I and phase II trials have found PEG-LD to be safe and effective in the treatment of platinum- and paclitaxel-refractory epithelial ovarian carcinoma. A new phase II trial is currently underway in similarly refractory patients with ovarian and other related cancers and various degrees of pretreatment. In addition, the efficacy of PEG-LD is being explored in combination with paclitaxel (Taxol), with cisplatin, and with hyperthermia. [ONCOLOGY 11(Suppl 11):38-44, 1997]

A majority of the more than 190,000 women diagnosed with breast cancer each year in the US[1] will receive some form of adjuvant therapy. Many breast cancer treatments cause decreases in circulating estrogen levels, which in turn can have a significant effect on bone mineral density; this condition is known as cancer treatment-induced bone loss (CTIBL). In this issue of ONCOLOGY, Reeder and Brufsky review the role of bisphosphonates in the setting of adjuvant breast cancer treatment. Both oral and intravenous bisphosphonates are effective in the prevention and treatment of CTIBL, and emerging data suggest that adjuvant bisphosphonate therapy may also affect breast cancer recurrence and survival. In considering the role of these medicines in early stage breast cancer, however, a number of important questions remain.

The introduction of prostate-specific antigen (PSA) as a reliabletumor marker for prostate cancer brought significant changes in theend points used for outcome reporting after therapy. With regard to adefinition of failure after radiation, a consensus was reached in 1996that took into account the particular issues of an intact prostate aftertherapy. Over the next several years, the consensus definition issued bythe American Society for Therapeutic Radiology and Oncology(ASTRO) was used and studied. Concerns and criticisms were raised.The sensitivity and specificity of this definition vs other proposals hasbeen investigated, and differences in outcome analyzed and compared.Although the ASTRO definition came from analysis of datasets on external-beam radiation and most of the work on this topic has been withthis modality, failure definitions for brachytherapy must be exploredas well. The concept of a universal definition of failure that might beapplied to multiple modalities, including surgery, should also be investigated,at least for comparative study and research purposes.

Early presentation of endometrial cancer permits effective managementwith excellent clinical outcome. The addition of hysteroscopy todilatation and curettage (D&C) in the evaluation of postmenopausalbleeding adds little to the detection of malignancy. Imaging studies suchas computed tomography, magnetic resonance imaging, and positronemissiontomography may be of use in determining the presence ofextrauterine disease in patients medically unfit for surgical staging.However, these studies are not sufficiently sensitive to replace surgicalstaging and have little role in routine preoperative evaluation. Clinicalstaging alone is clearly inadequate, as 23% of preoperative clinicalstage I/II patients are upstaged with comprehensive surgical staging.Preoperative tumor grade from D&C or office biopsy may be inaccurateand lead to an underestimate of tumor progression if used to determinewhich patients should be surgically staged. Clinical estimationof depth of invasion, with or without frozen section, is inaccurate andmay lead to underestimation of disease status when surgical staging isnot performed. The practice of resecting only clinically suspicious nodesshould be discouraged as it is no substitute for comprehensive surgicalstaging. Comprehensive surgical staging provides proper guidance forpostoperative adjuvant therapy, avoiding needless radiation in 85% ofclinical stage I/II patients. Finally, resection of occult metastasis withsurgical staging may improve survival.

The demographics of the US population continue to change dramatically, as the absolute number and proportion of older people relative to the remainder of the population increases. Last year, the number of persons older than 65 years was estimated to be 35 million, representing almost 13% of the overall population; by 2030, the older population is expected to double. Along with the general aging of the population, the percentage of persons older than 85 years is also growing rapidly, as is the ethnic and racial diversity within the older population.

Normal and hyperplastic prostate glandular epithelium does not express somatostatin receptors. Neuroendocrine prostatic cells contain bioactive secretory products such as chromogranin A, serotonin, and neuron-specific enolase. The stromal smooth muscle cells around glandular epithelium and ganglion cells of the prostatic plexus are positive for somatostatin subtype 2 receptors (sst 2).[1] In prostate cancer, however, there is nonhomogeneous distribution of sst 1. In the peritumoral veins of prostate cancer, sst 2 receptors were found by Reubi et al in 14 of 27 samples.[2]

Lung cancer is the most common cancer diagnosed in men and women in the United States, and is the leading cause of cancer death.Over 160,000 individuals died as a result of lung cancer in 2008.[1] This number amounted to more than the number of deaths from colon, breast, and prostate cancers combined. The majority of lung cancer cases are non–small-cell lung cancer (NSCLC), and the poor outcomes are attributed to the high rate of metastases associated with this disease.

Head and neck cancer and its treatment frequently cause changes in both speech and swallowing, which affect the patient's quality of life and ability to function in society. The exact nature and severity of the post-treatment changes depend on the location of the tumor, the choice of treatment, and the availability and use of speech and swallowing therapy during the first 3 months after treatment. This paper reviews the literature on speech and swallowing problems in various types of treated head and neck cancer patients. Effective swallowing rehabilitation depends on the inclusion of a video-fluorographic assessment of the patient's oropharyngeal swallow in the post-treatment evaluation. Pilot data support the use of range of motion (ROM) exercises for the jaw, tongue, lips, and larynx in the first 3 months after oral or oropharyngeal ablative surgical procedures, as patients who perform ROM exercises on a regular basis exhibit significantly greater improvement in global measures of both speech and swallowing, as compared with patients who do not do these exercises.
