Comparative intraperitoneal pharmacokinetics of three platinum analogues.

The pharmakokinetic profiles of intraperitoneally infused platinum analogues were determined in 13 women exhibiting minimal residual disease following surgery and systemic chemotherapy for epithelial ovarian cancer or fallopian tube carcinoma by following the disposition of tracer doses of 195mPt radiolabel. Six patients received iproplatin, four were given cisplatin and three received carboplatin. The present data demonstrate no difference in the disposition of total platinum between these three analogues, but differences in the kinetics of free platinum may exist.

Diethyldithiocarbamate chemoprotection of carboplatin--induced hematological toxicity.

Carboplatin therapy has a more favorable toxicity profile than cisplatin and, given in appropriate doses, is equivalent in efficacy to cisplatin for suboptimal ovarian cancer. However myelosuppression frequently curtails therapy with carboplatin. Diethyldithiocarbamate (DDTC) is a thiol compound and heavy-metal-chelating agent that has been shown to protect against carboplatin-induced bone marrow suppression in animal models. This pilot study was undertaken to evaluate the ability of DDTC to ameliorate the degree and/or duration of myelosuppression from carboplatin chemotherapy in patients with relapsed ovarian cancer. Ten patients who had previously demonstrated a response to platinum-based chemotherapy, were treated with single-agent intravenous carboplatin 400 mg/m2 administered over 30-60 min every 4 weeks. Patients received their first cycle of carboplatin without DDTC, and their second cycle with DDTC. DDTC at 600 mg/m2 was infused over 3 h commencing 30 min prior to carboplatin and was well tolerated. Treatment with DDTC did not decrease the degree of leukopenia or thrombocytopenia associated with carboplatin chemotherapy, nor did it decrease the duration of myelosuppression. This clinical study demonstrates no evidence of a bone-marrow-protective effect for this dose and schedule of DDTC in patients receiving carboplatin chemotherapy.

Diagnosis and clinical management in malignant Müllerian tumors of the fallopian tube. A report of four cases and review of recent literature.

Four out of 42 cases of primary tubal malignancy diagnosed in our histopathological laboratory were malignant mixed Müllerian tumors (MMMT). All four patients were postmenopausal with a mean age of 66.5 years at diagnosis. A correct preoperative diagnosis was made only in one case. Tumor staging (FIGO) revealed stage IIa, IIIc and IV. One patient died of postoperative pulmonary embolism, a second patient of an unknown cause five month after surgery and a third patient died of disease after 11 months with secondary deposits in pelvic peritoneum, omentum and paraaortic lymph nodes. The fourth patient is still alive. One patient received chemotherapy alone, one by radiation and chemotherapy and two patients by radiation alone. Tumor spread at the time of diagnosis and the residual tumor volume were the most important prognostic factors. All tumors were histologically the homologous type of MMMT (carcinosarcomas). No heterologous elements were found. Metastatic tumors showed only sarcomatous elements.

Evaluation of adjuvant therapy after surgery for primary carcinoma of the fallopian tube.

OBJECTIVE: To evaluate the impact of postoperative therapy (chemotherapy vs. irradiation) on overall survival. DESIGN: A nationwide retrospective analysis. SETTING: Hanusch-Krankenhaus, Department of Gynaecology, SUBJECTS: 115 patients with histologically proved primary carcinoma of the Fallopian tube: 49 received six treatment cycles of a cis-platinum regimen (group I), 24 patients were treated by full irradiation using 50 Gray minimum (group II). The two groups had a similar distribution of stage I and II; in the more advanced stages chemotherapy was the predominant method of treatment. RESULTS: The five-year survival rate was 53% for women receiving irradiation as against 27% for those given cis-platinum. If the analysis was restricted to those patients with comparable stage I and stage II lesions, the p-value (0.07) was of borderline significance. There was no advantage in adding abdominal to pelvic irradiation (P = 0.62). CONCLUSIONS: Stage I and stage II carcinoma is probably better treated postoperatively by radiotherapy than chemotherapy. Chemotherapy may have more therapeutic potential in patients with more advanced lesions.

Preoperative and postoperative CA-125 serum levels in primary fallopian tube carcinoma.

Levels of CA-125 were determined pre- and postoperatively in 13 patients with fallopian tube cancer. Values before surgery were significantly higher (Median 1220 IU/ml, 90-5000 IU/ml) compared with postoperative levels (Median 194 IU/ml, 67-880 IU/ml) (P = 0.0052). Correlation analysis with FIGO stage and grading failed to show any statistical significance, but a trend for a positive correlation with FIGO stage and preoperative values could be observed. The CA-125 antigen is expressed by fallopian tube carcinoma and should therefore be used in diagnosis and follow-up.

Benign solid teratoma of the fallopian tube with rupture into the rectum: report of a unique rectal tumor.

Solid teratoma of the fallopian tube is rare. A case of a benign solid teratoma of the fallopian tube that ruptured into the rectum is presented. This is believed to be the first report of this occurrence, which should be included in the differential diagnosis of the rectal mass. Any suspicion of this lesion should mitigate against a posterior approach for resection, as the rectum can be expected to be fixed to other pelvic viscera.

Radical lymphadenectomy in the primary carcinoma of the fallopian tube.

The primary carcinoma of the Fallopian tube is a highly aggressive tumor which can spread by the lymphatic route. The object of the present study was to evaluate the impact of radical pelvic and para-aortic lymphadenectomy on overall survival. Radical lymphadenectomy was performed on twelve patients in addition to hysterectomy and bilateral adnexectomy (group I). Twenty-eight patients subjected only to hysterectomy and adnexectomy formed the control group (group II). On average 47.6 lymph nodes were excised per patient. As long as the carcinoma was limited to adnexa and uterus (stages I and II), no lymph node metastases were found, only in stages III and IV were lymph node metastases detectable. Even though the median survival time of group I was considerably higher than of group II (43 versus 35 months), there was no statistically significant difference between the two groups (P < 0.65). Patients with stage III and stage IV disease had relatively longer median survival times if they had a lymphadenectomy. However, the difference was not statistically significant (P < 0.91). We cannot therefore recommend routine radical lymphadenectomy for primary Fallopian tube carcinoma. Whether or not lymph node dissection would lead to better results from rational selection of patient for adjuvant therapy is not known.

Treatment of fallopian tube cancer. Review of the literature.

OBJECTIVE: To contribute toward the understanding of the therapeutic management of fallopian tube cancer. METHODS: Recent studies related to the treatment of fallopian tube cancer were reviewed. RESULTS: Current evidence indicates that even patients in early stages have nodal disease, and often experience relapses in distant sites. In advanced stages, survival prolongation by the use of platinum-based chemotherapy has been demonstrated. Aggressive cytoreductive surgery followed by chemotherapy and negative second-look laparotomy offer the possibility of long-term survival. However, a significant fraction of patients eventually relapses after negative second-look laparotomy, and a poor survival rate after positive second-look laparotomy has been observed. CONCLUSIONS: This series suggests the need for thorough evaluation of lymph nodes at the time of surgery. The use of platinum-based chemotherapy is probably the best adjuvant therapy for both early stages and advanced stages. The clinical value of second-look laparotomy will remain limited until effective salvage therapy is developed. The potential benefits of neoadjuvant chemotherapy and the use of paclitaxel will be increasingly important.

Preoperative diagnosis of fallopian tube cancer by imaging.

Primary cancer of the fallopian tube (FTC) is among the most unusual gynecologic malignancies and rarely is diagnosed correctly before surgery. The imaging results of eight patients with FTC and four with benign tubal disease were analyzed. FTCs were small cystic or solid masses that typically were shaped like a sausage, a snail, or a gourd, regardless of clinical stage.

Clinical outcome and complications of laparoscopic surgery compared with traditional surgery in women with endometrial cancer.

INTRODUCTION: The purpose of this study was to evaluate the feasibility, clinical outcome and complications of laparoscopic surgery in women with endometrial cancer and to compare surgical outcome and postoperative early and late complications with results of traditional laparotomy. METHODS: Forty women with endometrial cancer underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Each patient operated by laparoscopy was matched by age, preoperative clinical stage and histology of the endometrial cancer with a patient treated by the same operation but using traditional laparotomy. Half of these patients underwent total pelvic lymphadenectomy and half had pelvic lymph node sampling. The groups were compared in clinical characteristics, surgical outcomes, recoveries and early and late postoperative complications. RESULTS: The patients in the laparoscopy group had less blood loss, more lymph nodes removed, shorter hospital stay but longer operation time than those treated by laparotomy. Only one (2.5%) laparoscopy was converted to laparotomy due to pelvic adhesions. There were no intraoperative complications in either group. Postoperative complications were more common (55.0%) in the laparotomy than in the laparoscopy group (37.5%). Only one major complication (2.5%) occurred among patients undergoing laparoscopy as compared with three (7.5%) major complications in the laparotomy group. Superficial wound infection was the most common (20%) infection in laparotomy patients while vaginal cuff cellulitis occurred in 10% of laparoscopy patients. Late (>42 days) postoperative complications were almost equally frequent (20.0 and 22.5%) in both groups. Lower extremity lymph edema or pelvic lymph cyst was found in 12.5% of all cases. As a result of surgical staging the disease of 6 women (15%) in both groups was upgraded. CONCLUSIONS: Laparoscopic surgery is a viable alternative to traditional surgery in the management of endometrial cancer. The surgical outcome is similar in both cases. In laparoscopic procedures the operation time is longer but the postoperative recovery time shorter than in laparotomy. Severe complications were limited in both groups, while wound infections can be avoided using laparoscopy.

Thrombocytopenia associated with second-line carboplatin-based chemotherapy for ovarian, fallopian tube, and primary peritoneal cavity cancers.

PURPOSE: There are limited data available in the oncology literature regarding the risk of thrombocytopenia associated with carboplatin-based second-line treatment of ovarian cancer, outside the setting of patients participating in clinical trials. METHODS: To examine this clinically-relevant issue, we conducted a retrospective review of the medical records of women with ovarian cancer treated in the Gynecologic Cancer Program of the Cleveland Clinic from 1994 through November 2003, who received >2 second-line carboplatin-based regimens. RESULTS: A total of 176 second-line carboplatin-based programs were delivered to the 152 patients (median age 61 years; range 39-87 years) identified through this review. A total of ten (7%) patients experienced >grade 2 thrombocytopenia, with only four (3%) patients developing platelet count nadirs <50.0 x 10(9)/l. No patient required discontinuation of platinum-based therapy due to the development of thrombocytopenia. CONCLUSION: Second-line carboplatin-based chemotherapy of ovarian cancer is associated with a low incidence of serious thrombocytopenia, if a strategy of selecting modest initial dose levels, and instituting rapid reductions in dose with the development of significant bone marrow suppression, is employed.
