RESUMO
PURPOSE: To report our recent experience managing four patients with brain metastases of gestational trophoblastic neoplasia (GTN), coordinating systemic chemotherapy with early neurosurgical intervention or stereotactic radiosurgery and intensive supportive care during initial therapy to prevent early mortality. MATERIALS AND METHODS: A series of four consecutive patients with brain metastases from high-risk Stage IV GTN managed at our institution in 2003 and 2005. Patients were assigned FIGO stage and risk score prospectively. Because of concern for chronic toxicity resulting from concurrent moderate dose methotrexate and whole brain radiation, an individualized multidisciplinary approach was used to manage patients. RESULTS: All four women presented with brain and pulmonary metastases; one had multiple liver metastases. Neurological symptoms at presentation included grand mal seizures in 2 patients, left upper extremity hemiparesis and headache each in 1 patient, while 1 patient was asymptomatic. Index pregnancies were term pregnancies in all patients with interval from prior delivery ranging from 2 weeks to 4 years. Two had received prior chemotherapy for postmolar GTN prior to the index pregnancy with incomplete follow-up. Initial hCG values ranged from 26,400 to 137,751 mIU/ml; FIGO risk scores were > or =16 for all patients. Systemic combination chemotherapy was initiated with etoposide and cisplatin followed by moderate/high-dose (500-1000 mg/m(2)) methotrexate combinations. Craniotomy was used before or during the first chemotherapy cycle to extirpate solitary lesions in 3 patients, while stereotactic radiosurgery was administered after the first cycle to treat two brain lesions in the remaining patient. None received whole brain radiation or intrathecal methotrexate. In one patient, selective angiographic embolization was used to control hemorrhage from multiple liver metastases. Two patients required ventilator support early in treatment to allow stabilization from intrathoracic hemorrhage and neutropenic sepsis with respiratory distress syndrome, respectively. Hysterectomy was performed in one patient after completion of salvage chemotherapy. All have completed maintenance chemotherapy and are in prolonged remission (12-24 months). Neurologic sequelae include persistent left upper extremity dyskinesia and weakness in one patient, and episodic grand mal seizures and pseudoseizures in a second patient with a pre-existing seizure disorder. CONCLUSION: This case series documents the utility for a multidisciplinary approach to the treatment of brain metastases from GTN. Using early craniotomy or stereotactic radiosurgery combined with etoposide-cisplatin and moderate/high-dose methotrexate combination chemotherapy, we were able to stabilize patients early in their treatment and avoid whole brain radiation therapy or intrathecal chemotherapy.

OBJECTIVE: A phase I/II study of Doxil combined with whole abdomen hyperthermia was conducted in patients with refractory ovarian cancer. Liposomal doxorubicin combined with hyperthermia has been shown to increase both liposomal delivery and drug extravasation into tumour xenografts resulting in enhanced cytotoxic effects. PATIENTS AND METHODS: Thirty patients with either recurrent or persistent epithelial ovarian cancer were enrolled. All patients had either measurable or assessable disease. Patients received intravenous (IV) Doxil at a dose of 40 mg m-2 as a 1-h infusion followed by whole abdomen hyperthermia. The phase I portion of the study was performed to determine the maximal tolerated dose (MTD) of hyperthermia. Quality of life (QoL) was performed at baseline, prior to each cycle and every 3 months. Plasma pharmacokinetic studies were performed with the first cycle. RESULTS: Ten patients participated in the phase I portion of the study which demonstrated that the MTD of hyperthermia was 60 min after either average vaginal and rectal temperatures of 40 degrees C had been achieved or after 30 min of power application, whichever was shorter. All 30 patients were either paclitaxel and/or platinum resistant initially or developed resistant disease. The median number of prior chemotherapeutic regimens was three (range 2-8) and six patients had been previously treated with Doxil. There were three partial responses for a response rate of 10% (95% CI: [2%, 27%]) and eight patients (27%; 95% CI: [12%, 46%]) had disease stabilization. The median time to progression or death was 3.4 months (95% CI: [2.6, 5.2]) and the median survival was 10.8 months (95% CI: [8.8, 17.4]). Twelve patients (40%) experienced palmar-plantar erythrodysesthesia (PPE), but only four (13%) experienced grade 3-4 PPE toxicity. Doxil systemic exposure was higher in those with grade 3-4 PPE compared to those with no PPE. None of the patients had grade 3-4 thermal toxicity due to hyperthermia. QoL was not decreased in patients responding to therapy. CONCLUSIONS: Therapy with intravenous Doxil and whole abdomen hyperthermia for patients with platinum/paclitaxel resistant ovarian cancer is feasible and does not negatively impact quality of life.

Twenty evaluable patients with squamous cell carcinoma of the cervix, who had previously received a cisplatin-containing regimen, were treated with amonafide 300 mg/m2 over 1 hour for 5 consecutive days every 3 weeks. One partial response (5%) was seen. Hematologic toxicity was substantial with severe or life-threatening events occurring as follows: leukopenia, 5 patients (25%); thrombocytopenia, 4 patients (20%); granulocytopenia, 2 patients (10%). One patient experienced acute bilateral open-angle glaucoma immediately after treatment, and another developed gastric ulceration with life-threatening gastrointestinal bleeding. In view of the low response rate and high toxicity, amonafide does not warrant further investigation as second-line chemotherapy in squamous cell carcinoma of the cervix.

From 1974-1990, 23 women with stage I and five with stage II epithelial ovarian carcinoma received intraperitoneal chromic phosphate (32P) as the only form of adjuvant therapy after complete debulking and comprehensive surgical staging laparotomy. Surgery consisted of total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy, peritoneal washings for cytology, multiple biopsies of pelvic and abdominal peritoneum, and selective pelvic and para-aortic lymphadenectomy. Intraperitoneal 32P therapy was administered a median of 7 days after laparotomy. Significant toxicity was minimal; none of these patients required surgery for bowel obstruction. Overall 5-year survival was 90 and 100%, but disease-free survival was only 65% (95% confidence interval [CI] 36-86%) and 60% (95% CI 12-81%) for patients with stage I and II disease, respectively. Two patients developed intraperitoneal and six systemic relapses; all patients received cisplatin regimens after relapse. Univariate analysis of age, stage, histology, Ovarian Cancer Study/Gynecologic Oncology Group risk status, lesion size, and presence or absence of capsular adhesions revealed that only an age of 50 or more years had an adverse effect on disease-free survival (P less than .03). This study suggests that determination of early-stage disease and host-tumor biology may be the most important factors in determining the survival of women with early ovarian cancer defined by comprehensive surgical staging. Intraperitoneal 32P does not appear to be effective adjuvant therapy in these women.

Two women developed apparently isolated recurrences of ovarian carcinoma involving prior incisions after receiving intraperitoneal radioactive chromic phosphate (P-32) adjuvant therapy for early epithelial ovarian carcinoma. Both are alive without evidence of disease at second-look laparotomy after surgical resection of the abdominal wall metastases and cisplatin-based combination chemotherapy. Mechanisms of cutaneous and incisional implantation metastases are discussed. Adjuvant therapy with intraperitoneal P-32 is unable to provide systemic therapy for occult metastatic disease. The favorable outcome in these cases probably reflects limited tumor burden at the time of recurrence and stands in stark contrast to other cases of soft tissue recurrences of ovarian carcinoma reported previously.

Forty-nine women with apparent Stage I and II ovarian carcinoma received intraperitoneal phosphate 32 as the only adjuvant therapy after primary surgery. In addition to bilateral salpingo-oophorectomy, 40 (82%) had analysis of peritoneal cytology, and 35 (71%) underwent omentectomy. Random peritoneal biopsies and retroperitoneal lymph node sampling were not done in any of these patients. The overall and disease-free survival rates were 86% and 75%, respectively, with no significant differences by stage, histologic grade, histologic type, or low-risk versus high-risk subsets recognized in patients who received comprehensive surgical staging. Seven (58%) of 12 patients had lymph node metastasis as the first site of recurrence, including two of three with late recurrences. Significant morbidity related to intraperitoneal chromic phosphate (32P) occurred in one (2%) woman. These results emphasize the need for comprehensive surgical staging of women with apparent early ovarian carcinoma to aid in the selection of appropriate initial adjuvant therapy.

Malignant peritoneal cytology in patients with endometrial carcinoma is a poor prognostic feature, identifying patients at high risk for early intra-abdominal recurrence. Between 1977 and January, 1983, 65 women with endometrial carcinoma who had malignant peritoneal cytology were treated with adjuvant intraperitoneal radioactive chromic phosphate P 32 suspension. Fifty-three patients (80%) were clinical Stage I, nine (14%) were Stage II, and three (7%) were clinical Stage III. Life-table estimates of disease-free survival were 89% for clinical Stage I patients and 94% for surgical Stage I patients beyond 24 months. One patient developed an intraperitoneal recurrence, four had simultaneous intraperitoneal and extraperitoneal recurrences, and six developed recurrences outside of the peritoneal cavity. Few significant acute complications occurred after therapy with radioactive chromic phosphate P 32 suspension. Chronic intestinal morbidity that required surgical correction was encountered in five of 17 patients (29%) who received adjuvant pelvic radiation, compared to none of the 48 patients (0%) who received only radioactive chromic phosphate P 32 suspension (p less than 0.001). Intraperitoneal instillation of radioactive chromic phosphate P 32 suspension is effective therapy for patients with malignant peritoneal cytology from endometrial carcinoma. Caution should be exercised when radioactive chromic phosphate P 32 suspension and external radiation therapy are combined.
