Phase II trial of topotecan and cisplatin in persistent or recurrent squamous and nonsquamous carcinomas of the cervix.

OBJECTIVE: Cisplatin is a standard treatment in advanced, recurrent cervical cancer. Because topotecan is an established treatment in gynecologic malignancies such as ovarian cancer and exhibits nonoverlapping toxicity with cisplatin, a phase II trial was conducted to evaluate the tolerability and antitumor activity of a cisplatin/topotecan doublet in persistent or recurrent cervical cancer patients. METHODS: Patients with bidimensionally measurable persistent or recurrent squamous cell and non squamous cell cervical cancer and adequate bone marrow were enrolled. Patients received 50 mg/m(2) of cisplatin intravenously over 1 h on Day 1 and 0.75 mg/m(2) of topotecan intravenously over 30 min on Days 1, 2, and 3 of 21-day cycles for six cycles or until disease progression. Tumor response and regimen toxicity were assessed using established Gynecologic Oncology Group criteria. RESULTS: Thirty-two of 35 enrolled patients were evaluable for toxicity and tumor response. All but 2 evaluable patients had received previous radiotherapy. No patient received prior chemotherapy. The cisplatin/topotecan doublet was well tolerated, with 77 and 78% of courses given without interruption or delay and at full doses, respectively. As anticipated, the most common toxicity was hematologic, with grade 3/4 neutropenia and thrombocytopenia reported in 30 and 10% of cycles, respectively. The overall response rate was 28% (9/32), with 3 complete and 6 partial responses. The antitumor response in nonirradiated fields (30%) was similar to the response observed in previously irradiated fields (33%), suggesting good drug penetration. Median duration of response was 5 months (range, 2 to 15+ months). An additional 9 (28%) patients achieved stable disease. Median survival was 10 months, with 3 patients in lasting remission. CONCLUSIONS: These results demonstrate that the cisplatin/topotecan combination is safe, well tolerated, and active in persistent or recurrent cervical cancer patients. A phase III, multicenter trial is under way (cisplatin/topotecan versus cisplatin) based on these favorable results to confirm the safety and efficacy profile in this patient population.

Prevention and treatment of breast cancer.

In the new millennium, practitioners who provide primary care for women of all ages must be well educated in the diagnosis and treatment modalities for breast carcinoma. This disease strikes one of eight women. That statistic alone should encourage diligent and persistent efforts to detect this disease early enough to prevent the large number of deaths annually Early detection will reduce the morbidity associated with breast cancer. Strong efforts are ongoing in the fields of genetics and breast cancer research to achieve earlier detection of breast cancer and a reduction in morbidity regardless of the stage of the breast carcinoma. As results of ongoing studies materialize and new studies are funded, it is hoped that more answers will emerge to combat the devastating effects of breast cancer.

Mammography.

Breast cancer is the most common female malignancy in the USA and second only to lung malignancy in cancer mortality. The only screening modality that effectively detects early breast cancer and decreases mortality is mammography. Because many females turn to obstetrician gynecologists for breast cancer screening, an understanding of the benefits and limitations of mammography and the breast imaging reporting and data system is imperative. Mammography remains the most cost effective and sensitive tool for early detection.

Inherited susceptibility to breast and ovarian cancer.

Approximately 5-10% of breast and ovarian cancer cases are due to an inherited susceptibility. The majority of inherited breast and ovarian cancer susceptibility is due to mutations in the BRCA1 and BRCA2 genes; however, other genes responsible for inherited susceptibility to these diseases are yet to be identified. A small proportion of inherited breast and ovarian cancers are due to other genetic cancer susceptibility syndromes including Li-Fraumeni syndrome, Cowden disease and hereditary non-polyposis colorectal cancer. It is recommended that individuals at risk for inherited susceptibility to breast and/or ovarian cancer who are requesting DNA testing be provided with pre-test genetic counseling and education and post-test counseling and follow-up to ensure that all aspects of genetic testing have been disclosed and that the patient has truly given informed consent.

The failed anti-incontinence mechanism: a flap valve or cecal wrap for surgical reconstruction.

PURPOSE: On a long-term basis patients with continent urinary diversions may have an acceptable number of complications, such as urinary incontinence. We report on a new surgical technique for treatment of the incompetent anti-incontinence segment. MATERIALS AND METHODS: Seven patients presented with a large capacity, low pressure reservoir and an incompetent anti-incontinence mechanism. The original anti-incontinence mechanism consisted of an intussuscepted reimplanted appendix (Mitrofanoff) in 2 patients, tapered ileum and reinforced ileocecal valve in 3, and tapered and reimplanted ileal segment in 2. Surgical reconstruction involved 2 stages: stage 1 - lengthening and tubularizing the cecum with the anti-incontinence segment and stage 2 - creation of the flap valve mechanism. Stage 2 required intraoperative modification when abundant peri-reservoir fibrosis, a thin-walled reservoir (cecal wrap) or an excessive thickened mesentery was encountered. RESULTS: After a mean followup of 7 months 6 of 7 patients performed catheterization every 4 hours and were continent. Several patients required a concomitant procedure with the incontinence revision. CONCLUSIONS: We describe a 2-stage technique for correction of a variety of untoward anatomical conditions related to a failed anti-incontinence segment with continent urinary reservoirs. Concomitant repair of other coexisting structural abnormalities related to the continent reservoir may also be necessary.

Natural history and clinical evaluation of the lumpectomy scar.

After lumpectomy with axillary dissection and radiation therapy, there are numerous changes that occur to the breast that, if unrecognized as routine, post-treatment changes, can lead to inappropriate intervention by the physician. The purpose of this study is to evaluate the time required to achieve stable post-treatment mammographic and physical findings. One hundred twenty-three patients age 56.6 years with a mean tumor size of 15.9 +/- 8.2 mm were observed every 6 months with a mean change in scar size of 16.7 +/- 10.6 mm. A scar never developed in 27 per cent and completely resolved or decreased in 90 per cent. Calcifications developed in 16 per cent of the patients; 40 per cent in the scar, 60 per cent outside the scar. Recurrence developed in 2 per cent of the patients at a mean time of 53 months and was believed to be favorably influenced by cytologic evaluation of the resection margins at the time of tumor excision. Stabilization or resolution of the post-treatment changes occurred within 24 to 36 months. The conclusion is for careful surgical and radiologic follow-up with examinations, fine-needle aspirations, and meticulous mammograms guiding the need for biopsy.

Treatment of advanced gynecologic malignancies with intraarterial chemotherapy and accelerated fractionation radiation therapy: a preliminary report.

The results of a pilot study employing the administration of intraarterial chemotherapy and accelerated fractionation radiotherapy for advanced gynecologic malignancies are reported. The protocol consisted of three treatment sessions every 3 to 4 weeks. Each session consisted of bilateral or unilateral catheterization of the hypogastric artery with the infusion of cisplatin 100 mg/m2 on Day 1 and 2-deoxy-5-fluorouridine (FUDR) 300 mg/m2 on Day 2. An accelerated fractionation schedule of external-beam radiation was begun on Day 1 consisting of 200 rads twice daily for 4 days (1600 rads per session). Eight patients entered the protocol, and seven completed external-beam radiotherapy. Five completed three intraarterial sessions, and three, two sessions. Five of seven evaluable patients had a complete local response. Local control was sustained fom 6 to 24 months in four patients. Complications included three sensorimotor neuropathies, one clinically insignificant catheter-related thrombosis, and three clinically significant radiation injuries. This multimodality treatment for locally advanced gynecologic tumors appears feasible with modification, and continued work exploring this approach is encouraged.

Evaluation of tamoxifen in persistent or recurrent nonsquamous cell carcinoma of the cervix: a Gynecologic Oncology Group study.

This study was undertaken to estimate the antitumor activity of tamoxifen in patients with persistent or recurrent nonsquamous cell carcinoma of the cervix. Furthermore, the nature and degree of adverse effects from tamoxifen in this cohort of individuals was examined. Tamoxifen citrate was to be administered at a dose of 10 mg per orally twice a day until disease progression or unacceptable side effects prevented further therapy. A total of 34 patients (median age: 49 years) were registered to this trial; two were declared ineligible. Thirty-two patients were evaluable for adverse effects and 27 were evaluable for response. There were only six grades 3 and 4 adverse effects reported: leukopenia (in one patient), anemia (in two), emesis (in one), gastrointestinal distress (in one), and neuropathy (in one). The objective response rate was 11.1%, with one complete and two partial responses. In conclusion, tamoxifen appears to have minimal activity in nonsquamous cell carcinoma of the cervix.
