Sarcoma after radiation therapy: retrospective multiinstitutional study of 80 histologically confirmed cases. Radiation Therapist and Pathologist Groups of the Fédération Nationale des Centres de Lutte Contre le Cancer.

PURPOSE: To evaluate the best strategy for treatment of sarcoma that occurs after radiation therapy. MATERIALS AND METHODS: Records were retrospectively reviewed for 80 patients with a confirmed histologic diagnosis of sarcoma that occurred after radiation therapy performed during 1975-1995. The patients were treated for breast cancer (n = 33, 42%), non-Hodgkin lymphoma (n = 9, 11%), cervical cancer (n = 9, 11%), benign lesions (n = 4, 5%), or other tumors (n = 25, 31%). Sarcoma occurred after a mean latency of 12 years (range, 3-64 years), with most (70%) developing in the soft tissue. Treatment included surgery (28 patients), surgery and chemotherapy (18 patients), chemotherapy only (15 patients), and radiation therapy (14 patients). RESULTS: By the end of the study, 51 patients were dead, including 46 due to sarcoma. Median survival was 23 months. Overall survival rates at 2 and 5 years, respectively, were 69% and 39% for patients treated with surgery, 10% and 0% for those treated with chemotherapy, and 52% and 35% for those treated with surgery and chemotherapy (P =.001). The 2- and 5-year rates for survival without recurrence were 54% and 32%, respectively. CONCLUSION: The results confirm the beneficial effect of surgery. Further study is needed to explore the roles of combined treatments.

Concomitant brain radiotherapy and vinorelbine-ifosfamide-cisplatin chemotherapy in brain metastases of non-small cell lung cancer.

AIM: To determine whether or not brain radiotherapy and concomitant three-drug chemotherapy is feasible and yields anti-tumour activity in patients with non-small cell lung cancer and brain metastases at time of presentation. PATIENTS AND METHODS: Twenty-three previously untreated patients suffering from non-small cell lung cancer and brain metastasis were prospectively included in this feasibility study. Most of the patients had neurological symptoms and an Eastern Collaborative Oncology Group (ECOG) performance index over 2. Treatment consisted of three courses of whole brain radiotherapy (18 Gy in 10 fractions) and vinorelbine, 30 mg/m2 on days 1 and 8, ifosfamide, 1.5 g/m2 daily from day 1 through day 3 with uromitexan uroprotection, and cisplatin, 100 mg/m2 on day 2. A cycle restarted every 28 days. RESULTS: Eighteen patients completed the three-cycle programme. All patients were affected by a grade 4 neutropenia and 14 of them experienced a febrile episode. Other toxicities were mild to moderate and manageable. Received-dose intensities of vinorelbine, ifosfamide and cisplatin were 80, 90 and 90%, respectively. Overall response rate was 30%. Specific evaluation of brain response demonstrated complete response for seven patients, and partial response in six (objective brain response rate, 56%). All responders benefited by a remission of symptoms and improvement of performance index. Median survival from start of protocol was 7.6 months. CONCLUSION: Although the high rate of toxicity requiring re-admission, concomitant brain radiotherapy plus vinorelbine, ifosfamide and cisplatin chemotherapy is feasible in patients suffering from brain metastasis, and demonstrates an anti-tumour activity for this particular subset of stage IV non-small cell lung cancer. The development of such an aggressive approach needs further comparative evaluation.

Nine breast angiosarcomas after conservative treatment for breast carcinoma: a survey from French comprehensive Cancer Centers.

OBJECTIVES: To conduct a survey of the angiosarcomas developing after breast conservation for carcinoma in the French Cancer Centers, to study the evolution of these cases in detail, and to review literature in an attempt to propose an optimal treatment scheme. MATERIAL AND METHODS: Eleven of the 20 French Cancer Centers agreed to research and retrospectively analyze all angiosarcomas discovered in patients previously treated by conservative treatment. The majority of the patients were node negative, T1N0M0. The mean age of the patients at the time of primary breast cancer treatment was 62.5 years, and 69 years at the diagnosis of the angiosarcoma. RESULTS: During the last two decades, nearly 20,000 patients have been treated conservatively in these 11 centers, and only 9 cases of angiosarcoma were found. The median latency period between the treatment of the breast carcinoma and the diagnosis of the breast angiosarcoma was approximately 74 months, with a range of 57-108 months. Mastectomy was performed as the main treatment of this angiosarcoma. All recurrences after mastectomy for the angiosarcoma appeared within 16 months after the mastectomy. A median time of recurrence was found to be 7.5 months, regardless of the treatment. The angiosarcomas appeared to be very aggressive, and chemotherapy, radiotherapy, and sometimes hyperthermia could only palliate the condition for a short time. After the diagnosis of angiosarcoma, the median survival was 15.5 months, showing a particularly poor prognosis. Only 1 patient of 9 is alive without progressive disease at 32 months after salvage mastectomy for the recurrence of the angiosarcoma. Precise data obtained from 11 centers show that, of 18115 breast carcinomas treated conservatively, only 9 breast angiosarcomas are reported, which represents a prevalence of 5 cases of angiosarcoma per 10,000, which is the same prevalence for primary breast angiosarcomas occurring in healthy breasts. CONCLUSION: Angiosarcoma developing after breast conserving therapy for carcinoma is a rare event, and induction of it by treatment is controversial. However, early diagnosis is essential and it appears that radical mastectomy gives the highest chance of cure and the best long-term survival.

Neoadjuvant etoposide, ifosfamide, and cisplatin followed by concomitant thoracic radiotherapy and continuous cisplatin infusion in stage IIIb non-small cell lung cancer.

OBJECTIVE: To determine the applicability and safety of an ifosfamide, cisplatin, and etoposide (VIP) regimen as a neoadjuvant chemotherapy to a concomitant thoracic radiotherapy and cisplatin continuous infusion in locally advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Forty-four patients (stage IIIb in 43 and stage IIIa in 1) entered a study of VIP, followed by concomitant thoracic radiotherapy and cisplatin continuous infusion. Chemotherapy consisted of three courses of cisplatin 25 mg/m2, ifosfamide 1.5 g/m2 (with uroprotection), and etoposide 100 mg/m2 given on days 1 to 4 of a 21-day cycle with hematopoietic support using recombinant human methionyl granulocyte colony stimulating factor. Patients who achieved a response or a stabilization were planned to receive a split-course normofractionated thoracic radiotherapy (first course: 30 Gy/10; 4-week rest period; second course: 25 Gy/10). A continuous cisplatin infusion of 6 mg/m2 daily was administered using an autonomous chemotherapy delivery device. Total plasma platinum titration was performed daily during the two courses in five of the patients. Analyses were done on an intent-to-treat basis. RESULTS: Thirty-nine of the 44 patients received the three-cycle chemotherapy program. Received dose intensity was 82%. Thirty-eight patients received the radiotherapy and, among them, 35 received the complete concomitant continuous cisplatin infusion. Objective (complete) response rates were 48% (7%) at the end of chemotherapy and increased up to 61% (16%) by the end of radiotherapy. At the end of the first radiotherapy cycle, the mean total plasma platinum concentration was twice as high as that of the residual postinduction chemotherapy concentration. During induction chemotherapy, myelosuppression was the limiting toxicity requiring hospital readmission in 23 patients. During radiotherapy, the main toxicity was acute esophagitis. A relatively high rate of pulmonary fibrosis was observed using the subjective objective management analytic--late effects of normal tissue score without life-threatening pulmonary function impairment. None of the patients died from toxic reactions. Probability of survival at 1, 2, and 3 years was 49%, 19%, and 5%, respectively. Primary cause of failure was a local relapse in 63% of the patients, brain metastases in 24%, and hematogeneous metastases to other sites in 13%. CONCLUSION: Neoadjuvant VIP followed by concomitant radiotherapy-chemotherapy is feasible, but the split-course radiotherapy did not prevent a high rate of local recurrences. The high rate of toxic reactions requiring hospital readmission limits further development of such an aggressive regimen in NSCLC.

Concomitant brain radiotherapy and high-dose ifosfamide in brain relapses of lung cancer.

PATIENTS AND METHODS: Twenty patients with lung cancer and brain metastasis were prospectively included in this feasibility study (four small-cell and 16 non-small-cell lung cancers). There were two previously untreated patients and 18 pretreated patients for whom brain metastases constituted the first relapse after a treatment-free interval following chemotherapy for the primary lung cancer. Most of the patients had neurological symptoms and an ECOG performance index over 2. Treatment consisted of three courses of whole brain radiotherapy (18 Gy in 10 fractions) and ifosfamide: 3 g/m2 daily from day 1 through day 4, i.e., during the first four days of radiotherapy with uromitexan uroprotection and haematopoietic support (r-HuG-CSF). RESULTS: Seventeen patients completed the three-cycle programme. Sixteen patients had grade 4 neutropenia and six of them experienced a febrile episode. Other toxicities were mild to moderate and manageable. The received dose-intensity of ifosfamide was 90%. Response evaluation demonstrated stable disease for two patients, partial response for eight, complete response for six and progression for four. All responders benefited by a remission of symptoms and improvement of performance index. Median survival from start of protocol was 13 months. CONCLUSION: Brain radiotherapy plus high-dose ifosfamide is feasible in patients suffering from brain recurrences of lung cancer.

Ductal carcinoma in situ of the male breast. Analysis of 31 cases.

From 1970 to 1992, 31 pure ductal carcinoma in situ (DCIS) of the male breast treated in 19 French Regional Cancer Centres were reviewed. They represent 5% of all breast cancers treated in men in the same period. The median age was 58 years, but 6 patients were younger than 40 years. TNM classification (UICC, 1978) showed 12 T0 (discovered only by bloody nipple discharge), 10 T1, 5 T2 and four unclassified tumours (Tx). 11 patients (35.5%) had clinical gynecomastia, and three (10%) had a family history of breast cancer. 6 patients underwent lumpectomy, and 25 mastectomy. Axillary dissection was performed in 19 cases. 6 cases received postoperative irradiation. 15 out of 31 lesions were of the papillary subtype, pure or associated with a cribriform component. The size of the 12 measured lesions varied from 3 to 45 mm. All lymph nodes sampled were negative. With a median follow-up of 83 months, 4 patients (13%) presented a local relapse (LR), respectively, at 12, 27, 36 and 55 months. 3 of these patients had been initially treated by lumpectomy. In one case LR was still in situ, but already infiltrating in the 3 others. Radical salvage surgery was performed in 3 cases, but one patient developed metastases and died 30 months later. The last patient was treated by multiple local excisions and tamoxifen. One 43-year-old patient developed a contralateral DCIS and three others developed a metachronous cancer. The aetiology and risk factors of male breast cancer remain unknown. Gynecomastia, which implies an imbalance between androgen and oestrogen, may be a predisposing factor. As in women, DCIS in the male breast has a good prognosis. Total mastectomy without axillary dissection is the basic treatment. Frequently, the first symptom is a bloody nipple discharge. The age of occurrence is younger than for infiltrating carcinoma, suggesting that DCIS is the first step in the development of breast cancer.

Results of postoperative radiation therapy in medullary carcinoma of the thyroid: a retrospective study by the French Federation of Cancer Institutes--the Radiotherapy Cooperative Group.

Between 1971 and 1989, 59 patients received external radiation therapy with a curative intent. There were 25 females and 34 males, ranging in age from 19 to 87. No patients had distant metastasis at the onset of treatment. The majority of patients had a total thyroidectomy (55/59), generally combined with neck dissection. Residual tumour was left in 11 cases, and 44 patients had positive cervical nodes. Using megavoltage radiotherapy, the whole neck and the upper mediastinum area were most often irradiated through a large anterior Y-shaped field without laryngeal shielding. The mean dose to the tumoral bed was 54 Gy. Dysphagia was observed in 32 patients (11, 17 and 5 scores were grade 1, 2 and 3, respectively). Dyspnea occurred in five cases and in two of these cases, it was considered to be severe. Local recurrences were noted in 18 (30%) patients, most of them occurring within the fields of irradiation. Parameters such as age, sex, total dose, irradiated volumes or cervical node enlargement did not modify the local control rate. The same conclusions can be drawn for distant failures. Thirty five patients are still alive and among them, 24 have no evidence of disease. The average length of survival is 70.5 months and is shortened by the occurrence of distant failures except in patients with bone metastases.
