The role of radiation therapy after incomplete resection of penile cancer.

PURPOSE: To retrospectively assess the outcome in patients treated with adjuvant radiotherapy for penile cancer. PATIENTS AND METHODS: Between 1987 and 2006, 24 patients (median age, 62.7 years; range, 35.5-90.4 years) with squamous cell carcinoma of the penis (T1, n = 10; T2, n = 11; T3, n = 3) received megavoltage external radiotherapy (n = 22) or (192)Ir high-dose-rate brachytherapy (n = 2) following total penectomy (n = 7), partial penectomy (n = 10), or local excision (n = 7); lymphadenectomy was performed in eight patients. In 14 patients, radiotherapy was delivered after incomplete tumor resection, and in 20 patients the planning target volume included the regional lymph nodes. Median total dose of external radiotherapy was 56 Gy/1.8-2 Gy (range, 50-60 Gy). Brachytherapy was given with a total dose of 45 Gy/3 Gy. RESULTS: During a median follow-up of 58.4 months, penile or perineal recurrence was found in four patients giving a 5-year local control rate of 74.8%. Regional failure occurred in two patients. 5-year metastases-free survival and progression-free survival rates were 86.7% and 64.5%, respectively. Four patients died due to tumor progression. The actuarial 5-year cause-specific and overall survival rates were 84.3 and 56.6%, respectively. CONCLUSION: Radiation therapy is a successful method of treatment for penile cancer in terms of local control and organ preservation after microscopically incomplete surgery. Radiotherapy of the regional lymph nodes might also be effective in preventing regional recurrence and can be considered in case of high-risk features and following excision of extensive lymph node involvement.

Lymphatic fistulas: obliteration by low-dose radiotherapy.

BACKGROUND: Lymphatic drainage from the surgical wound is an uncommon but challenging complication of surgical intervention. Protracted lymphorrhea contributes to morbidity, favors infections and results in a prolonged hospital stay. Treatment options include surgical ligation and, more conservatively, leg elevation, continuous local pressure, subatmospheric pressure dressings, and low-dose radiotherapy. This study examines the efficacy of low-dose radiotherapy. PATIENTS AND METHODS: 17 patients (19 fistulas) with lymphorrhea following vena saphena harvesting (n = 7), femoropopliteal bypass (n = 3), varicose vein surgery (n = 2), hip arthroplasty (n = 3; five fistulas), shunt surgery (n = 1), and piercing (n = 1) were referred for external radiotherapy. Depending on the depth of the fistula, orthovoltage (n = 12), electrons (4-11 MeV; n = 2) or photons (8 MV; n = 3) were used. Fractions between 0.3 Gy and 2 Gy were applied; the individual total dose depended on the success of the radiotherapy, i. e., the obliteration of the lymph fistula, and varied from 1 to 12 Gy. RESULTS: In 13 out of 17 patients complete obliteration of the fistula was achieved. Interestingly, this was achieved in nine of the ten patients irradiated with total doses of

Regional nodal recurrence in the management of breast cancer patients with one to three positive axillary lymph nodes. Outcome of patients following tangential irradiation without a separate nodal field.

PURPOSE: To examine the prognosis of breast cancer patients (T1-3, one to three positive axillary lymph nodes) and locoregional failure rate after breast-conserving therapy/modified radical mastectomy and adequate axillary dissection following tangential radiotherapy without irradiation of the regional lymph nodes. PATIENTS AND METHODS: From 1994 to 2002, the medical records of 183 breast cancer patients (T1-3, one to three involved axillary lymph nodes) were examined in order to identify those experiencing regional nodal recurrence, with or without local recurrence. The median age of the patient population was 58 years (range, 28-86 years). All patients underwent surgical treatment, either breast-conserving therapy (n = 146) or modified radical mastectomy (n = 37). The median number of lymph nodes removed was twelve (range, seven to 26 nodes). Irradiation was given to the breast through tangential fields. Chemotherapy was administered to 101 patients (55%), hormonal therapy to 124 (60%), and combined systemic treatment to 47 (26%). RESULTS: The median observation time was 44.4 months (range, 11-102 months). Of the 14 patients (7.7%) with a relapse, six (3.3%) had a local recurrence, five (2.8%) a regional relapse, and three (1.6%) a simultaneous recurrence. Nine out of 14 patients with locoregional relapse developed distant failure subsequently and seven of them (78%) died of the disease. CONCLUSION: Regional recurrence is uncommon among patients with one to three positive axillary lymph nodes treated with surgery, adequate axillary dissection, and tangential field irradiation only. The authors conclude that regional nodal irradiation should not routinely be given following adequate axillary dissection when only one to three lymph nodes are positive.

Long-term results after external radiotherapy in age-related macular degeneration. A prospective study.

PURPOSE: To prospectively evaluate the short- and long-term efficacy of external radiotherapy (RT) in patients with age-related macular degeneration (AMD) by comparing two different dose schedules. PATIENTS AND METHODS: In this prospective, nonrandomized, comparative study including 80 patients, the efficacy of external RT with a total dose of 14.4 Gy (group A, n = 40) and 25.2 Gy (group B, n = 40) was compared. Patients of group A were irradiated between September 1995 and July 1996, patients of group B between August 1996 and November 1997. 67 patients presented with occult choroidal neovascularization (CNV), 13 with classic subfoveal lesions. Complete ophthalmologic investigation was performed before RT, at intervals of 3 months during the 1st year after RT, and of 6 months thereafter. RESULTS: 12 months after RT, vision deteriorated in 85% (14.4 Gy) and 65% (25.2 Gy) of patients. Central visual field decreased with both dose schedules. There was no morphological benefit in neovascular changes. After 48 months, complete follow-up was possible in 46 patients who showed a significant loss of vision similar to the natural course of AMD. CONCLUSION: External RT of AMD with 14.4 Gy as well as with the escalated dose of 25.2 Gy showed a poor beneficial outcome after 6 and 12 months, respectively. After a follow-up of 4 years, visual outcome in irradiated patients was similar to the natural course of the disease. A conspicuous efficacy of RT in prevention of blindness could not be demonstrated.

Extracapsular extension in positive axillary lymph nodes in female breast cancer patients. Patterns of failure and indications for postoperative locoregional irradiation.

BACKGROUND AND PURPOSE: There has been little information regarding lymph node-positive breast cancer patients with extracapsular extension (ECE). The aim of this study was to evaluate the role of ECE in predicting survival and relapse rates. PATIENTS AND METHODS: From 1994-2002, 1,078 lymph node-positive women with breast carcinoma were treated at our institution, whereas 301 patients (27.9%) presented with ECE. 91 patients (30.2%) were identified as having three or less lymph nodes involved, 27.9% patients four to six, 15.6% patients seven to nine, and 26.2% patients ten or more nodes, respectively. The median age was 58.4 years (range: 28-84 years) and the median follow-up 34 months (range: 2-99 months). Nodal irradiation was given to patients with four or more positive lymph nodes. Chemotherapy was administered to 69.8%, hormonal therapy to 53.2%, and combined systemic treatment to 26% of patients. RESULTS: The 1-, 3-, and 5-year overall survival (OS) was 98%, 84%, and 73%, the 1-, 3-, and 5-year disease-free survival (DFS) 95%, 69%, and 58%, and the 1-, 3-, and 5-year metastasis-free survival (MFS) 96%, 73%, and 60%. The relapse rates were 6.6% (local), 0.3% (supraclavicular), 0.7% (isolated axillary), 1% (local + axillary), and 0.7% (local + supraclavicular), respectively. 81 patients (27%) developed distant metastases. In December 2002, 245 patients (81.4%) were alive, 202/245 without progression, 32/245 with distant metastases, 5/245 with local/locoregional recurrence, and 6/245 patients with local and distant failure. CONCLUSION: Isolated axillary nodal failure remains low in lymph node-positive patients with ECE. Balancing the risks and benefits of irradiation, we continue to recommend that complete axillary irradiation is not routinely indicated after adequate axillary dissection.

Palliative treatment of unresectable bile duct tumours.

PURPOSE: Report on outcome of intraluminal high-dose-rate iridium-192 (HDR-Ir192) brachytherapy with or without external radiotherapy in patients with unresectable bile duct tumours suffering from symptoms of malignant obstructive jaundice. MATERIAL AND METHODS: Fourteen patients (mean age: 63 years) who were unsuitable for surgical resection on preoperative evaluation/laparotomy or inoperable due to poor general condition were referred for palliative radiotherapy. After percutaneous transhepatic drainage, HDR-Ir192 brachytherapy was performed with a single dose of 2.5 Gy. Brachytherapy was given twice a day with at least a 6-h interval for 2 days, 2 or 3 days apart, up to a total dose of 10 Gy. Five patients received small-volume external radiotherapy (RT) (45 - 50.4 Gy/1.8 Gy) additionally. RESULTS: Palliation with relief of the aggravating symptoms of obstructive jaundice was achieved in all patients. The actuarial 2-year survival rate of all patients was 11.9 % with a median survival of 6.5 months. Patients treated with brachytherapy alone had a median survival of 4.5 months as compared with 6.5 months after combined internal and external irradiation (log rank, P = 0.95). CONCLUSION: Patients with advanced unresectable bile duct cancer face a dismal prognosis; however, biliary drainage, and intraluminal brachytherapy with or without external RT, seem to be able to improve quality of life in the remaining time span.

Fractionated intraluminal HDR 192Ir brachytherapy as palliative treatment in patients with endobronchial metastases from non-bronchogenic primaries.

AIM: To evaluate the efficacy of iridium-192 high-dose rate (HDR) endobronchial brachytherapy for the palliation of symptoms caused by endobronchial metastases of non-bronchogenic primaries. PATIENTS AND METHOD: Between 1991 and 1998, eleven patients (female n = 3, male n = 8; age: median 66 years, range 44-81 years) underwent intraluminal HDR brachytherapy for histologically confirmed endobronchial metastases from non-pulmonary primary tumors of various sites like urogenital tract (n = 5), gastrointestinal tract (n = 3), ear/nose/throat (n = 2) and breast (n = 1). The median time between diagnosis of the primary non-bronchogenic tumor and histopathological diagnosis of the endobronchial metastases was 39 months, range 1-99 months. A total dose of 15-20 Gy was delivered in three to four fractions of 5-6 Gy once a week. No palliative chemotherapy was added. RESULTS: Median follow-up after palliative brachytherapy was 15 months (range 1.4-59 months). Objectively, complete endoscopic response was observed in three (27%) patients, and in five (46%) others partial opening of the initially obstructed airway was achieved. Treatment was judged unsuccessful in three (27%) patients. No patient showed up with local progression. At date of analysis five patients were alive with documented residual tumor (80%) or complete response (20%). Relief of symptoms occurred in the vast majority of patients (n = 8, 73%). CONCLUSION: HDR intraluminal brachytherapy palliates symptoms in patients suffering from endobronchial metastases of non-pulmonary primary tumors. The applied treatment is a safe, effective and well tolerated palliative procedure leading to an improved patient quality of life.
