By transforming radio signals into a surgical laser, surgeons at the University of Pennsylvania Cancer Center are able to use high-energy radiofrequency sound waves to destroy inoperable primary and metastatic liver tumors.

The Oncology Nursing Society (ONS) recently received grants from Genentech, Inc., to fund two educational projects. A $96,000 grant will fund the ONS National Conference on Cancer Nursing Research to be held in 1999, and a $30,930 grant

As Drs. Sabbatini and Spriggs point out in their review, the majority of ovarian cancer patients continue to present with advanced-stage disease, and only a minority are cured after primary surgery and chemotherapy. At present, recurrent disease is best viewed as a chronic illness that requires ongoing management. A number of therapeutic options are available, but opportunities for cure remain limited. My comments will focus on post-remission therapy, small-volume residual disease, intraperitoneal therapy, secondary cytoreductive surgery, choice of second-line chemotherapy, and participation in phase II studies.

Women smokers who overestimate their body size may be more likely to continue smoking, said researchers at The Miriam Hospital in Providence. Results of a study led by Teresa K. King, PhD, of the hospital’s Center for Behavioral and

Women with common variations in the class of enzyme known as glutathione S-transferase (GST), which detoxify carcinogens, are at increased risk of developing breast cancer, according to researchers at the Johns Hopkins School of Public Health.

Despite the activity of initial chemotherapy in ovarian cancer, the majority of women presenting with advanced disease will ultimately experience disease recurrence and be required to consider second-line, or salvage, chemotherapy options. The well-written, informative article by Sabbatini and Spriggs provides a fairly comprehensive overview of important factors to consider when determining the most appropriate treatment options in this clinical setting.

Drs. Weber and Petrelli review much of the literature regarding patient outcomes after local excision alone, as well as local excision plus chemoradiotherapy, in patients with various stages of low rectal adenocarcinoma. The authors apparently were unaware that the Radiation Therapy Oncology Group (RTOG) experience with local excision plus chemoradiation, which antedated the Cancer and Leukemia Group B (CALGB) study, will soon be in print to provide further multi-institutional support for these methods along with much greater follow-up. They also omitted our long-term data (median follow-up of survivors is 67 months) showing the very low locoregional recurrence rates in patients with T2 cancers treated by local excision and chemoradiotherapy.[1]

In this extensive review of the literature, Weber and Petrelli have nicely placed into perspective and documented the methods used in and results of most of the studies on local excision for rectal cancer. Although I agree with many of their conclusions, it is difficult for me to agree with the title of their article, "Local excision for rectal cancer: An uncertain future."

In 1996, the total in-hospital charges for the primary treatment of women with breast cancer with a modified radical mastectomy averaged $10,000 throughout the United States. The total charge (hospital plus physician’s fees) varied by 95% between the high charge reported in New York ($12,690) and the low charge in Michigan ($6,510). The hospital portion of the bill averaged 65% of the total and ranged from 51% in New York to 74% in Virginia. The average length of stay for these women was 2.39 days and ranged from 3.18 days in New York to 1.69 and 1.66 days in Washington and Arizona, respectively. The average charge for a partial mastectomy was $8,760, with notable variations between states. The Texas total charge was the highest ($12,890, some 47% above the US norm) and more than twice the low charge in Ohio ($6,080, 31% below the US average). The physicians’ charges averaged $3,330 for the country as a whole and accounted for 38% of the bill. This proportion ranged from 46% of the total in New York to 70% in Indiana and Colorado. The average length of hospitalization for a partial mastectomy was 1.84 days. On average, women remained in the hospital for the longest time in New Jersey (2.78 days) and for the shortest time in Oregon and Massachusetts (1.40 days and 1.45 days, respectively).[ONCOLOGY 12(6):889-902, 1998]

The distribution of abdominal serous carcinoma in the female ranges from ovarian carcinoma with no tumor involvement of the peritoneum to peritoneal carcinoma with no evidence of carcinoma in the ovary. For the purposes of investigation and patient care, it has been necessary to formulate criteria to distinguish tumors that are most probably primary ovarian carcinomas from those that are most likely primary peritoneal cancers.

Drs. Eltabbakh and Piver present a comprehensive review of the management and prognosis of patients with extraovarian primary peritoneal carcinoma (EOPPC). Increased recognition and more precise definition have led many physicians and scientists to recognize EOPPC as a distinct clinical entity with a unique etiology. However, staging and treatment criteria for EOPPC have been modeled after criteria for papillary serous ovarian cancer, which is clinically and histologically similar. The Gynecologic Oncology Group (GOG) has allowed the inclusion of patients with EOPPC into clinical trials designed for patients with epithelial ovarian cancer.
