In 10 patients with heavily pretreated Hodgkin's disease (stage IVA or IVB) a third-line salvage therapy consisting of CCNU, etoposide and chlorambucil (CECh) was tested. All patients were resistant to both COPP and ABVD. Acceptance and tolerance of CECh were very satisfactory. The observed response rate (3 complete remissions and 4 partial remissions) is encouraging. The survival time after CECh therapy is in excess of 32 months (complete remission) and 15 months (partial remission). The main possible adverse effect is a prolonged myelosuppression. The CECh therapy is an effective alternative chemotherapy in patients resistant to both COPP and ABVD, moderately toxic, easy to administer and well tolerated in heavily pretreated patients.

Radiotherapy has been standard therapy for locally advanced squamous cell cervical cancer. Neoadjuvant chemotherapy is being studied to improve responses and survival. We report a phase II study in locally advanced squamous cell cervical cancer (FIGO stages III and IVA) using chemotherapy with bleomycin, methotrexate and cisplatin (BMP) followed by radical radiotherapy. Of the 35 patients, 31 in stage III and 4 in stage IVA, 3 complete responses (CR) and 22 partial responses (PR) were achieved after chemotherapy treatment. Thirty-one patients completed radiotherapy; 19 achieved CR and 4 PR. Five-year actuarial survival for the entire group was 45% (95% confidence interval, 37-53%) with a median survival of 56 months. Patients with CR had a significantly better survival: the 5-year actuarial survival was 74% (95% CI, 59-89%). Recurrence developed in 4 of 19 patients. The most frequent side-effects were nausea and vomiting. Myelosuppression and impaired renal function also occurred. There was no evidence of radiotherapy toxicity enhancement. The stage and Karnofsky index were significant prognostic factors. It is concluded that BMP chemotherapy in advanced cervical cancer is effective and, followed by radiotherapy, allows a good control of this tumor. The group of patients with complete response have a low rate of recurrences and a long survival chance.

Between August 1990 and January 1992, 184 patients with squamous cell carcinoma of the cervix, FIGO stage IIB-IVA, were randomized to receive either two cycles of bleomycin, ifosfamide-mesna, and cis-platinum (BIP) chemotherapy (CT) followed by radiotherapy (RT) ("CT-RT group," n = 94) or RT alone (RT group, n = 90). In the CT-RT group, of 89 evaluable patients, 64 responded: complete response (CR) 4 (4.5%) and partial response 60 (67.5%). Of the remaining 25 patients, 23 had stable disease and 2 progressed. Eighty of 89 patients completed RT as planned. Following RT 56 (70%) achieved CR, 19 (23.7%) had residual disease, and 5 (6.3%) had progressed. CT responders had a better response to RT: 83% (49/59) vs 33.3% (7/21), P < 0.01). The stage of disease, histologic grade, duration of symptoms, and history of smoking had no influence on the response to CT. Patients aged > 45 years and those with Hb > 10 g/dl had significantly better response. Nausea/vomiting, alopecia, grade I-II myelosuppression, diarrhea, and mucositis were the major side effects of CT. Two patients died of CT toxicity. In the RT group, 88 patients were evaluable: 61 (69.3%) patients achieved CR, 25 had residual disease, and 2 progressed. The side effects of RT were cystitis, proctitis, and local skin reaction. These were equally distributed between the two groups. There was no significant difference in overall and disease-free survival in the two groups.

A combination of cisplatin (80 mg/m2) and methotrexate (200 mg bolus and 400 mg as a 12-hour infusion) was given to 40 patients who developed local recurrence of cervical cancer after radiotherapy. A maximum of six courses was given at monthly intervals. Twenty-five of the forty (63%) evaluable patients responded, of which 4 (10%) responded completely. A symptomatic response, with reduction of pain, leg oedema, vaginal discharge and breathlessness was seen in 27 (68%) of patients. The median survival of all patients was 11 months. Toxicity was moderate; WHO grade 1 or greater was observed in 83% for nausea and vomiting, 67% for myelosuppression and 47% for mucositis. This combination chemotherapy is active in the treatment of recurrent cervical cancer and a modification of this regimen is currently being assessed as neo-adjuvant therapy in patients with Stage IIB-IVA cervical cancer.

A prospective study with a newly designed schedule of concomitant chemoradiotherapy was initiated for 42 patients with previously untreated squamous cell carcinoma of the uterine cervix. Their ages ranged from 34 to 77 years, median 57 years. There were 13 FIGO stage IIB, 1 IIIA, 27 IIIB, and 1 IVA. Radiotherapy was administered using 1.8 Gy/day, 5 days a week, to the whole pelvis (50.4 Gy/28 fractions) with local boost if indicated. Intracavitary brachytherapy of 5 Gy for five times was delivered after 1-2 weeks of rest. The first 21 patients received concomitant chemotherapy of biweekly PEB regimen (100 mg/m2 etoposide + 50 mg/m2 cisplatin + 50 mg/m2 bleomycin) for two to three cycles during external irradiation. The chemotherapy for the latter 21 patients was modified to weekly PEBF (50 mg/m2 etoposide + 20 mg/m2 cisplatin + 10 mg/m2 bleomycin + 800 mg/m2 5-FU, mixed in normal saline, 24-hr continuous iv infusion) for five to six cycles. All except 1 patient achieved complete response (97.6%) and sustain so after a median follow-up time of 30 months. There were three relapses--one with persistent pelvic disease and two with distant metastasis. Two-year overall survival and disease-free survival rates were 97.6 and 92.9%, respectively. Myelosuppression was moderate but fully recovered. Other acute toxicities were tolerated except for 1 patient who encountered grade IV radiation colitis with cecum perforation and required surgery. As to late morbidity, the incidence of radiation proctitis was high (21.4%) but of a mild degree, with 1 patient needing repeated transfusion. One patient developed chronic cystitis with an acontractile bladder. Our preliminary results show that concomitant chemoradiotherapy for advanced cervical carcinoma is both feasible and effective with acceptable toxicities. Further follow-up is mandatory to ensure whether this high complete response protocol will translate into long-term local control and survival.

A phase II trial was performed to assess the efficacy and toxicity of a combination of ifosfamide (IFX), cisplatin (CDDP), and vinorelbine (VNB) as neoadjuvant chemotherapy (NAC) for untreated advanced cervical carcinoma (ACC). Between October 1995 and February 1998, 40 patients were entered in this study. Their median age was 43 years (range: 23-74 years). International Federation of Gynecology and Obstetrics stages were: IIB, 23; IIIB, 13; and IVA, 4. Therapy consisted of: IFX 2,000 mg/m2 1-hour (H) IV infusion days 1 to 3; 2-mercaptoethanesulfonic acid sodium salt (mesna) 400 mg/m2 IV bolus H 0 and 4, and 800 mg/m2 by mouth H 8, days 1 to 3; VNB 25 mg/m2 20-minute IV infusion days 1 and 8; and CDDP 75 mg/m2 IV day 3. Cycles were repeated every 28 days for a total of three courses. Both staging and response (R) assessment were performed by a multidisciplinary team. An objective response (OR) was observed in 24 of 40 patients (60%; 95% confidence interval, 45-75%). Four patients achieved complete response (CR) (10%); 20 partial response (50%); 12 patients stable disease (30%); and 4 progressive disease (10%). Eight of 24 patients (33%) with OR underwent radical surgery, and histologic CRs were recorded in 2 of them. The remaining patients received definitive radiotherapy after NAC. The dose-limiting toxicity was myelosuppression. Leukopenia occurred in 32 patients (80%) and was grade III or IV in 14 patients (36%). Peripheral neuropathy occurred in 9 patients (22%), whereas myalgias occurred in 10 (25%). Constipation was observed in 9 patients (23%); emesis occurred in 35 patients (88%). There were no therapy-related deaths. These results indicate that IFX/CDDP/VNB is an active combination for ACC with moderate toxicity. Implementation of this regimen in a multimodal therapy protocol deserves further study.

Cutaneous T-cell lymphoma (CTCL) can be associated with painful, pruritic, disfiguring lesions. As part of a multicenter, randomized phase III trial in patients with heavily pretreated advanced and/or recurrent CTCL, the effects of an interleukin-2 receptor-targeted fusion protein, denileukin diftitox (DAB389IL-2, ONTAK), on patient-rated overall quality of life (QOL), skin appearance, and pruritus severity were evaluated. A total of 71 patients with stage IB-IVA CTCL received intravenous denileukin diftitox 9 microg/kg/day or 18 microg/kg/day over 15-60 minutes for 5 consecutive days on an outpatient basis; cycles were planned for every 21 days for a total of 8 cycles over 6 months. Prior to each treatment cycle, patients were evaluated for disease response and were asked to self-rate their overall QOL via the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire, skin appearance (7-point scale), and pruritus severity (10-cm visual analogue scale). Composite FACT-G and most individual subscale scores (physical, social/family, emotional, and functional well being) in documented responders (n = 21) gradually increased during the study period, generally reaching statistical significance (P < 0.05) by cycle 3, and were significantly (P < or = 0.041) higher than the scores of nonresponders at endpoint. Additionally for responders, assessments of skin severity and pruritus severity showed significant (P < or = 0.05) improvements at study endpoint compared with baseline. Adverse transfusion-related events (eg, hypersensitivity reactions, flu-like syndrome) were common during cycles 1 and 2, and vascular-leak syndrome occurred in 25% of patients. Denileukin diftitox was not associated with any clinically significant myelosuppression. Heavily pretreated patients with advanced and/or recurrent CTCL who responded to denileukin diftitox therapy showed significant improvements in self-rated overall QOL, skin appearance, and pruritus severity.

Rhabdomyosarcoma is the most common sarcoma of childhood. Fortunately, the goal of cure is realistic for the majority of patients with localized tumors. However, management of these patients remains challenging. The fact that the tumor arises in a wide variety of primary sites, some of which are associated with specific patterns of local invasion, regional lymph node spread, and therapeutic response, requires physicians to be familiar with site-specific staging and treatment details. In addition, rhabdomyosarcoma requires multimodality therapy that can be associated with significant acute toxicities and long-term effects, particularly when administered to young children. These factors sometimes present a dilemma as to the best approach to optimize the chance of cure, minimize toxicity, and respect quality of life. The purpose of this review is to discuss 'optimal' management of this complicated tumor. Since the tumor is relatively rare, requires highly specialized care, and important management questions remain to be answered, optimal management of rhabdomyosarcoma includes enrollment in clinical trials whenever possible. Appropriate management begins with establishing the correct pathologic diagnosis, histologic subtype, primary site, extent of disease (International Society of Pediatric Oncology [SIOP]-TNM-Union Internationale Contre le Cancer stage or Intergroup Rhabdomyosarcoma Study Group [IRSG] stage), and extent of resection (IRSG group). Cooperative groups throughout North America and Europe have defined risk-adapted treatment based on these factors; this treatment requires a coordinated management plan that includes surgery, chemotherapy, and usually radiotherapy. The surgical approach for rhabdomyosarcoma is to excise the primary tumor whenever possible without causing major functional or cosmetic deficits. Wide excision is difficult in some primary sites and can be complicated by the fact that the tumor grows in a locally infiltrative manner so that complete resection is often neither possible nor medically indicated. Incompletely resected tumors are generally treated with radiotherapy. The cooperative groups reduce the dose of radiation based on the response of the tumor to chemotherapy and delayed primary resection to differing degrees. Response-adjusted radiation administration may reduce the long-term effects of radiotherapy, such as bone growth arrest, muscle atrophy, bladder dysfunction, and induction of second malignant neoplasms; however, it may also be associated with an increased risk of tumor recurrence. All patients with rhabdomyosarcoma require chemotherapy. A backbone of vincristine and dactinomycin with either cyclophosphamide (VAC) or ifosfamide (IVA) has been established. Risk-adapted treatment involves reducing or eliminating the alklyating agent for patients with the most favorable disease characteristics. Clinical trials are ongoing to improve outcomes for higher risk patients; newer agents, such as topotecan or irinotecan, in combination with VAC or use of agents in novel ways are being investigated. Acute and long-term toxicities associated with these chemotherapy regimens include myelosuppression, febrile neutropenia, hepatopathy, infertility, and second malignant neoplasms. A 5-year survival rate >70% has been achieved in recent trials for patients with localized rhabdomyosarcoma. However, the outcome for patients who present with metastatic disease remains poor. In the future, risk-adapted classification of rhabdomyosarcoma will likely be based on biologic features, such as the presence of chromosomal translocations or specific gene expression profiles. It is hoped that newer therapies directed at specific molecular genetic defects will benefit all patients with rhabdomyosarcoma.

The purpose of this study was to evaluate the efficacy and toxicity of cisplatin plus gemcitabine chemotherapy and intensity-modulated radiation therapy (IMRT) for locoregionally advanced nasopharyngeal carcinoma (NPC). A total of 54 patients (stage IIB: 6, stage III: 24, stage IVA-B: 24) with locoregionally advanced NPC were treated with cisplatin 25 mg/m(2) intravenously on days 1-3, and gemcitabine 1,000 mg/m(2) of 30-min intravenous infusion on days 1 and 8, every 3 weeks for two cycles as neoadjuvant chemotherapy. Two cycles of the same regimen were administered as adjuvant chemotherapy 28 days after the end of radiotherapy. The prescription doses were 66-70.4 Gy to the gross tumor volume (GTV), 66 Gy to positive neck nodes, 60 Gy to the high-risk clinical target volume and 54 Gy to the low-risk clinical target volume. The overall response rate to neoadjuvant chemotherapy was 88.6%. Toxicity was mainly grade 1/2 myelosuppression. All patients completed IMRT. The median follow-up duration was 30 months (range, 12-60 months). The 3-year locoregional control, metastasis-free rate and overall survival were 94.9%, 86.2% and 87.7%, respectively. Severe late toxicities included grade 3 trismus in one patient, grade 3 hearing impairment in one patient and cranial nerve XII palsy in one patient. No grade 4 late toxicities were observed. A combination of cisplatin plus gemcitabine chemotherapy and intensity-modulated radiotherapy for locoregionally advanced NPC is well-tolerated, convenient, effective and warrants further studies.
