RESUMO
PURPOSE: To determine retrospectively the outcome of postoperative radiation therapy in male breast cancer. Local/distant control was assessed with attention to age, stage, lymph node involvement, histopathological differentiation and hormone receptor status. MATERIALS AND METHODS: Thirty-one male patients were irradiated postoperatively at the chest wall (mean dose 50 Gy) and 16 patients received radiation to regional lymph nodes. Tumour distribution by stage was: stage 0 (9.7%), stage I (22.6%), stage II (32.2%) and stage III (35.5%). Nine patients were subjected to additional hormone therapy and three patients to chemotherapy. RESULTS: Local control was achieved in 30/31 (96.8%) patients. Kaplan-Meier estimates of overall survival (OS), disease specific (DSS) and disease free survival (DFS) at 5 years were 77% (95% confidence interval (CI), 0.61-0.93), 84% (CI, 0.69-0.98) and 73% (CI, 0.57-0.91), respectively. Five-year DFS for stage 0 + I, II and III was 100, 56.3 and 67.3%, respectively. Favourable results were observed in patients with negative axillary nodes with 5-year OS/DFS of 90.9% (CI, 0.74-1.0). For lymph node positive patients DFS was 71% (CI, 0.4-1.0). Patients who presented lymph node metastases with extracapsular extension the 5-year OS was 80% (CI, 0.45-1.00), but the DFS was 0%. Stage of disease, lymph node involvement and histological differentiation were found to have statistically significant influence on DFS, but not on OS. CONCLUSION: Application of postoperative radiotherapy approved in females resulted in one local relapse in our study population. Other treatment modalities (hormone therapy/chemotherapy) should continue to be considered a necessary treatment option for appropriately selected patients.

The aim of this study was to verify the value of additional external beam irradiation (EBR) after endoscopic palliation, regarding quality of life and survival rate. From January 1988 to December 1995, 99 patients with esophageal carcinoma (squamous cell carcinoma 61; adenocarcinoma 38) were reviewed, there were 84 males (mean age: 67 years) and 16 females (mean age: 65 years). Seventeen patients were in stage IIb, 45 stage III and 37 patients in stage IV. HDR-brachyradiotherapy (mean: 14.7 Gy) was carried out in all patients. Additional EBR (mean: 47.8 Gy) after endoluminal palliation was done in 51 cases. At 6-months follow-up swallowing of a semi-solid diet at least was possible in all patients and dysphagia was found with significant difference in favour to EBR only in stage IV (p=0.011). The Karnovsky performance status showed a difference in favour of EBR for stage III and IV (p=0.040 and p=0. 049, respectively). The median overall survival for EBR compared to no EBR was 10 and 7 months, with a 12 months survival rate of 60% and 16% (p=0.0012). However, considering different stages and EBR versus no EBR a significant difference in survival could only be found for stage IIb (p=0.031), a trend in favour of EBR could be found for stage III (p=0.0985) and stage IV (p=0.0543). Tumor regrowth 6-12 months after treatment occurred in 31 cases and was successfully treated with Nd-YAG laser in 25 and stenting in 6 cases. Postirradiation fibrotic stenosis occurred in 12 cases. Improved survival rates after additional EBR can only be expected in stage IIb. However, in case of advanced esophageal carcinoma and fair performance status, EBR after endoluminal palliation help to maintain quality of life.

Primary small cell carcinoma of the esophagus is a rare and aggressive disease. We report on our experience with two patients having a small cell cancer of the esophagus, being treated with photodynamic therapy combined with irradiation and induction-chemotherapy as well as a review of literature. Both patients were admitted with severe dysphagia, weight loss and a Karnovsky performance status of 90. Diagnostic work-up revealed tumor-stenosis in the proximal third in one and in the distal third in the other case. Clinical staging showed T4N2M0 and T3N2M0, pure small cell carcinoma. Due to dysphagia and lymph node enlargement, local and systemic therapy were considered as first-line treatment. Restaging after three cycles of induction-chemotherapy revealed partial response in both cases. Esophagectomy as a second-line treatment was considered. However, in the preoperative period, one patient developed motorical aphasia. The CT-scan of the brain showed multiple brain metastases. External beam irradiation and further chemotherapy was initiated. The patient died 12 months after admission. The other patient revealed anatomical inoperability at the staging laparoscopy. External beam irradiation and a second session of PDT was performed. The patient is still alive, 12 months after his first admission. The biological behavior of this aggressive disease and metastases in about 50% of patients at admission, as well as significant dysphagia makes combined systemic and local treatment necessary. Nevertheless, after reviewing the literature, esophagectomy and adjuvant chemotherapy may have an advantage pertaining to survival time when anatomical and functional operability is given.

In our outpatient clinic 25 patients with Graves' ophthalmopathy were treated, 21 women, mean age 58.8 years (range 19-74 years) and 4 men, mean age 47.5 years (range 38-56 years). In the female group two showed euthyroid Graves' ophthalmopathy and one Hashimoto's disease; in the male group one showed euthyroid ophthalmopathy. Treatment was done depending on the findings of the NOSPECS-classification in identical way for each group. Final results were obtained three and six months after therapy, at that time all patients were euthyroid. In five patients (two men and three women) sicca-treatment was sufficient because the ophthalmopathy improved by therapy of the thyroid disease only. Three women were treated by oral steroids over three months and had a complete remission. Nine women were treated by oral steroids and external radiation, six of them showed major improvement but in one case orbital decompression had to be done. Somatostatin therapy was done over six months in six women who showed no change after oral steroids plus radiation. Out of them five showed major improvement but in spite of a positive octreoscan in one case orbital surgery had to be performed. Two men were treated by oral steroids and external radiation without change of disease, somatostatin therapy was not done because of a negative octreoscan. With the exception of one nonsmoking woman in whom orbital surgery had to be done, the treatment results were worse in smokers.

Since several decades, radiotherapy is included in the multimodal treatment concept of Graves' disease. By using orbital irradiation alone or in combination with oral corticosteroids up to two thirds of the patients respond to the treatment and achieve improvement of soft tissue signs and extraocular muscle impairment.

OBJECTIVE: To investigate the influence of radiation therapy on the development of disciform lesions in patients with age-related macular degeneration (AMD). DESIGN: A prospective, nonrandomized, comparative trial (patient self-controlled). PARTICIPANTS: Forty eyes with exudative AMD involving the central fovea in 40 consecutive patients were enrolled in this study. INTERVENTION: Radiation was administered to the posterior pole with an 8-mV photon beam from a linear accelerator. A dose of 14.4 Gy, 1.8 Gy per day, five fractions per week was delivered through a single port. MAIN OUTCOME MEASURES: The visual acuity and the morphologic characteristics, demonstrated by fundus photography, fluorescein, and indocyanine green angiography, were investigated before treatment and every 3 months after treatment over a period of 24 months. In 10 patients with bilateral disease the disciform lesions were compared. RESULTS: Twenty five patients could be followed regularly over the period of 24 months. The disciform lesions occurring after radiation were classified in three types. Type I (10 patients) was characterized by being smaller than 2 DD in size, with little fibrotic tissue underneath the retina, but pronounced retinal pigment epithelial changes. Type II (seven patients) showed extensive growth of the choroidal neovascularization (CNV) extending to and beyond the arcades with angiographically active loops in the peripheral parts. Eight patients had type III lesions develop characterized by a size greater than 2 DD but fewer than 6 DD and by a different amount of fibrotic tissue, hemorrhage, and lipid. Type I scarring was significantly associated with occult CNV without pigment epithelial detachments, whereas type II scarring was associated with classic CNV at the initial presentation (P<0.05). CONCLUSIONS: Although no severe side effects have been reported after radiation therapy for AMD, a subgroup of patients may experience extensive growth of CNV after radiation, causing greater functional damage than occurs spontaneously.

AIM: To determine the effect of external beam radiotherapy on subfoveal choroidal neovascularization in age-related macular degeneration. PATIENTS AND METHODS: Between September 1995 and July 1996, 40 patients (9 males and 31 females; mean age 74 years, range 61 to 83 years) were included in a prospective study. Eight patients had classic, well-defined neovascularisations, 32 patients had occult lesions. Complete ophthalmic investigations included visual acuity contrast sensitivity as well as fluorescein and indocyanine green angiographic examinations prior to treatment and 1, 3, 6, and 12 months after radiotherapy. External beam radiotherapy (8-MV photons) was delivered with a total dose of 14.4 Gy in 8 fractions of 1.8 Gy per day (Figures 1 and 2). The field size averaged 5.5 x 4.5 cm. RESULTS: No treatment related morbidity during or after treatment was obtained. After 6 months follow-up the visual acuity was improved in 2 (5%) patients and maintained at pretreatment level in 17 (42%) patients. However, 12 months post treatment a stable situation was found in 6 (15%) patients and a decrease in visual acuity in 34 (85%) patients (Table 1). The central visual fields deteriorated significantly from 16.5 decibel (dB) to 12.4 dB. The enlargement of exudates and neovascular membranes increased 5- to 7-fold. At 12 months after treatment, 3 (7.5%) patients stated that they had improved vision subjectively, 12 (30%) patients had no change and 25 (62.5%) patients suffered from subjective decrease in visual acuity. CONCLUSIONS: Using a total dose of 14.4 Gy/1.8 Gy no difference concerning visual acuity and exudative changes in comparison to the natural history on age-related macular degeneration was obtained after 12 months. However, the results of multicenter studies are to be awaited.

UNLABELLED: Background and Objective We wanted to determine the role of additional photodynamic therapy in a multimodal approach for the treatment of patients with advanced cancer of the gastro-esophageal junction. Study Design/Materials and Methods We reviewed 53 patients, after endoluminal palliation, with advanced cancer of the gastro-esophageal junction. Combined dilatation and retrograde tumor disobliteration with Nd-YAG laser before photodynamic therapy (PDT), brachyradiotherapy, or both, became necessary in 12 patients. Brachyradiotherapy was carried out in all patients. PDT before brachyradiotherapy was performed in 25 patients. The endoluminal treatment was completed by external beam irradiation in 30 patients (15 cases with PDT and 15 without PDT) with an at least fair performance status. RESULTS: Photodynamic therapy showed a significant difference regarding the mean opening of the tumor stenosis (mean, 6.4 mm; P = 0.0002), the mean decrease in tumor length (3.1 cm; P = 0.00001) and the increase in median survival (13. 8 months; P = 0.001). The combined multimodal approach by using PDT, brachyradiotherapy and external beam irradiation showed a median survival of 16.8 months. However, additional external beam irradiation showed no significant difference (P = 0.11). The rate of severe complications was 5.7%. The mortality rate was 1.9%. CONCLUSION: Photodynamic therapy has been shown to be an effective treatment for palliation of advanced cancer at the gastro-esophageal junction. The use of PDT combined with irradiation was associated with an acceptable survival rate, low rates of complications and reasonable quality of life.

PURPOSE: This study reports clinicopathological features and outcome of thymic tumors. Twenty-seven patients with invasive thymoma and 6 patients with thymic carcinoma who had received radiotherapy either primary or postoperatively were analyzed retrospectively. PATIENTS AND METHODS: All 33 patients were irradiated with a mean dose of 50 Gy after complete resection (16 patients), partial resection (9 patients) or biopsy (8 patients). Staging was done according to the Masaoka classification; there were 12 Stage II, 12 Stage III and 9 Stage IV patients. RESULTS: In patients with invasive thymoma Stage II to IV (median follow-up 54.4 months) Kaplan-Meier estimates of overall survival (OS), disease-specific (DSS) and disease-free survival (DFS) at 5 years were 63.7% (95% confidence interval [CI], 42 to 84%), 88.3% (CI, 75 to 100%) and 77.4% (CI, 58 to 95%), respectively. Among the prognostic factors tested, such as age, myasthenia gravis, completeness of surgery and histologic subclassification, total radiation dose, and Masaoka Stage, the latter was the only significant predictor of improved survival (p = 0.04). Considering local control, radiation dose was a significant prognostic factor (p = 0.0006). In patients with thymic carcinoma (median follow-up 43.4 months) 5-year DSS, and DFS were 22.2% (CI, 0 to 60%) and 16.7% (CI, 0 to 46%), respectively. Thymoma as compared to thymic carcinoma had a statistically significant better DSS (p = 0.007) and DFS (p = 0.0007). CONCLUSION: Postoperative radiotherapy with sufficient doses plays an important role as adjuvant treatment in complete or incomplete resected invasive Stage II to III thymoma. In unresectable thymoma Stage III to IV as well as in thymic carcinoma a multimodality approach should be considered to improve survival.
