Perimesencephalic subarachnoid hemorrhage as a rare delayed complication of radiation therapy in a patient with parotid basaloid squamous cell carcinoma.

In this case report, we address a rare entity of parotid cancer: basaloid squamous cell carcinoma, which was surgically unresectable and had thus far only been treated with radiation therapy. Following twenty years of continuous remission, our patient presented with an acute perimesencephalic subarachnoid hemorrhage. The cause of the acute perimesencephalic subarachnoid hemorrhage was a delayed complication of radiation therapy.

DUCHESS: an evaluation of the ductal carcinoma in situ score for decisions on radiotherapy in patients with low/intermediate-risk DCIS.

BACKGROUND: Identification of women with DCIS who have a very low risk of local recurrence risk (LRR) after breast-conserving surgery (BCS) is needed to de-escalate therapy. We evaluated the impact of 10-year LRR estimates after BCS, calculated by the integration of a 12-gene molecular expression assay (Oncotype Breast DCIS Score®) and clinicopathological features (CPFs), on its ability to change radiation oncologists' recommendations for RT after BCS for DCIS. METHODS: Prospective cohort study of women with DCIS treated with BCS. Eligibility criteria were as follows: age > 45 years, tumor ≤ 2.5 cm, and margins ≥ 1 mm. Radiation oncologists provided 10-year LRR estimates without RT and recommendation for RT pre- and post-assay. Primary outcome was change in RT recommendation. RESULTS: 217 patients were evaluable, with mean age = 63 years, mean tumor size = 1.1 cm, and mean DCIS Score = 32; 140 (64%) were in the low-risk (<39), 32 (15%) were in the intermediate-risk (39-54), and 45 (21%) were in the high-risk groups (≥55). The assay led to a change in treatment recommendation in 76 (35.2%) (95%CI 29.1-41.8%) patients. RT recommendations decreased from 79% pre-assay to 50% post-assay (difference = 29%; 95%CI 22-35%) due to a significant increase in the proportion of patients with a predicted low LRR (< 10%) post-assay and recommendations to omit RT for those with a low predicted risk. The assay was associated with improved patient satisfaction and reduced decisional conflict. CONCLUSION: The DCIS Score assay combined with CPFs identified more women with an estimated low (<10%) 10-yr LR risk after BCS, leading to a significant decrease in recommendations for RT compared to estimates based on CPFs alone.

Functional cranio-spinal irradiation: A hippocampal and hypothalamic-pituitary axis sparing radiation technique using two IMRT modalities.

Cranio-spinal irradiation (CSI) treatment of embryonal tumors is associated with long-term endocrine and neuro-cognitive sequelae. As an example, the radiation regiment for standard risk medulloblastoma is 23.4 Grays (Gy) CSI followed by a boost of 30.6Gy to the tumor bed. We hypothesize that a novel CSI technique, which we named "Functional" CSI (F-CSI) can reduce the dose to the hypothalamic-pituitary axis (HPA) and hippocampi compared to standard CSI (S-CSI) without sacrificing coverage. In this study, we compared the efficacy of Volumetric Modulated Arc Therapy (VMAT) and Helical Tomotherapy (HT) in delivering this novel CSI technique. Plans were constructed from 10 patients with embryonal tumors previously treated at our institution. Target volumes and organs at risk were delineated as per our local protocol and the ACNS0331 Atlas. The HPA and hippocampi contours were verified by an experienced neuro-radiologist. Primary objective was to achieve a D95% to the prescribed dose of 23.4Gy for CSI and 30.6Gy for the boost. Dmean ≤18Gy was assigned to the HPA and hippocampi. A two-sided t-test was used for comparison. F-CSI in both modalities were able to achieve the D95% target coverage. Hot spots (D2%) were lower with HT for both the CSI component (p = 0.03) and boost component (p < 0.01). VMAT was able to achieve better conformality (p < 0.01). Compared to S-CSI, both F-CSI modalities were able to achieve a significant decrease in dose to the HPA and Hippocampi. The average S-CSI HPA and Hippocampi Dmean were 23.9Gy and 23.8Gy. In contrast, respective F-CSI Dmean were 13.9Gy and 17.2Gy in VMAT and 15Gy and 15.9Gy in HT. The average composite (F-CSI plus boost) Dmean to the HPA and hippocampi often exceeded 18Gy. Compared to S-CSI, F-CSI with VMAT and HT were capable of achieving acceptable coverage while sparing the HPA and hippocampi. However, the addition of the boost component often exceeded the mean dose of 18Gy. This may be overcome with more conformal modalities for the boost phase such as stereotactic radiotherapy or proton therapy.

IMRT sparing of normal tissues in locoregional treatment of breast cancer.

PURPOSE: This clinical study was designed to prospectively evaluate the acute and moderately-late cardiac and lung toxicities of intensity modulated radiation therapy delivered by helical tomotherapy (IMRT-HT) for locoregional breast radiation treatment including the internal mammary nodes (IMN). MATERIAL/METHODS: 30 patients with stage III breast cancers have been accrued in this study. All patients received adjuvant chemotherapy. Target volumes were defined as follows: the PTV included breast/chest wall, axillary level II, III, infra/supraclavicular, IM nodes CTVs plus 3 mm margins. The heart with subunits and the lungs were defined as critical organs. Dose to PTV was 50 Gy in 25 fractions. Acute toxicities were assessed every week and 2 weeks post treatment using the CTCAE v3.0.scale. The moderately-late toxicities were assessed clinically plus by cardiac myoview perfusion tests scheduled at baseline, 3 and 12-month follow-up, as well a CT chest at the 6 month follow-up. The data analysis is descriptive. RESULTS: All participants completed the 5-week course of radiation without interruption. Skin erythema was modest and mainly grade 1-2 between the 3rd and the 5th week of radiation treatment. Only 4/30 patients experienced grade 3 skin reactions, mostly seen 2 weeks post radiation. Only 5 patients demonstrated grade 1 or 2 dyspnea, but 3 of them already had symptoms pre-radiation treatment. With a median follow-up of 58 (24-76) months, there have been infrequent moderately-late side effects. Most were grade 1 and were sometimes present at the baseline assessment. Cardiac myoview tests done at baseline and 1-year follow-up for 15 out of 18 left sided breast cancers did not show any abnormalities related to radiation. The 6-month follow-up chest CT-scans done for 25 out of 30 patients showed minimal anterior lung fibrosis for 7 patients and were completely normal for the other 18. No locoregional recurrence has been recorded and the 5-year survival is 78% (95% CI: 70-97%). CONCLUSION: IMRT-HT for locoregional breast radiation is very well tolerated with minimal acute or moderately-late side effects. Cardiac and respiratory tests did not show any strong evidence of significant treatment related abnormalities. TRIAL REGISTRATION: clinicaltrials.gov: http://NCT00508352.

Role of fine-needle aspiration in the surgical management of pancreatic neuroendocrine tumors: utility and limitations in light of the new World Health Organization classification.

CONTEXT: Pancreatic neuroendocrine tumors (Panc-NETs) are rare and tend to get overshadowed by their more prevalent and aggressive ductal adenocarcinoma counterparts. The biological behavior of PancNETs is unpredictable, and thus management is controversial. However, the new World Health Organization classification has significantly contributed to the prognostic stratification of these patients. Concurrently, there have been advances in surgical techniques for benign or low-grade pancreatic tumors. These procedures include minimally invasive and parenchyma-sparing operations such as laparoscopy and enucleation. OBJECTIVE: To report on the utility and limitations of fine-needle aspiration in the preoperative evaluation and management of PancNETs. DESIGN: This was a retrospective review of our institutional tumor database from 2002 to 2012. There were 25 cases of PancNETs that were localized and staged by medical imaging and diagnosed by fine-needle aspiration. RESULTS: Fourteen patients underwent laparotomy, with some requiring only limited surgery; 4 had laparoscopic resections; 4 were serially observed without surgical intervention; and another 3 were inoperable. After a mean follow-up of 37 months, more than half of the patients had no evidence of disease, including most of those who underwent minimally invasive surgery. CONCLUSIONS: Fine-needle aspiration is a useful diagnostic adjunct to medical imaging in the preoperative evaluation and management of PancNETs. However, there are limitations with regard to grading PancNETs using this technique.

The Emotional and Psychological Impact on Radiation Therapists of Treating Children.

PURPOSE: The aim of this study was to determine the psychological effects and difficulties that radiation therapists (RTs) experience while treating paediatric patients. This study is intended to provide some information to assist RTs in their occupation and to complement the literature on this topic. METHODS: A survey was conducted to capture data on the emotional effects and opinions of RTs at The Ottawa Hospital Regional Cancer Centre (TOHRCC) treating children with cancer. A questionnaire was created specifically for this study standardized to TOHRCC conditions and methods and inspired from the limited literature around this issue. The study converged on the reactions of RTs while children received radiation treatment at TOHRCC and the impact on their emotional state around this component of their practice. The questionnaire was distributed electronically via e-mail to all RTs within the Radiation Therapy Department at TOHRCC. RESULTS: This study involved 62 of 104 RTs employed at TOHRCC who completed the survey of 20 questions and submitted their responses. Due to the sample size, statistical correlations and links between variables were limited. The questionnaire was analysed based on the answers given by the RTs on the provided Likert scale for each question. The questionnaire showed that gender and age played no major role in the RTs' ability to cope mentally. Half of the RTs had children themselves; and of these, 66% indicated that having children made it somehow more difficult to cope emotionally with paediatric patients. Seventy-five percent of all RTs indicated that the emotional state of parents or care givers of the affected children played a key role in the anxiety they felt during a child's treatment. Eighty-one percent of RTs stated that treating children caused higher anxiety levels than treating adults. Finally, our survey suggests that time constraints play a large part in the RTs' stress level during treatments. CONCLUSION: Overall, treating children did not cause much more distress than treating adults. Results from this survey were used to create a new tool describing the cognitive stages in children to help RTs treat paediatric patients in the future.

Precedence for prostate brachytherapy.

PURPOSE: To identify the earliest practitioners of prostate brachytherapy. METHODS AND MATERIALS: Review of contemporary literature. RESULTS: Radiotherapy has been used for benign prostatic ailments as early as 1902. Prostate cancer was first treated by teletherapy in 1904. Several urologists, in Paris and Vienna, applied intracavitary radium for prostate disease in 1908-1909. We present evidence that Henri Minet was the first to perform prostate brachytherapy, as early as 1908. CONCLUSION: Brachytherapy has been used to treat prostate cancer for more than a century.

The management of radiation treatment error through incident learning.

PURPOSE: To assess efficacy of an incident learning system in the management of error in radiation treatment. MATERIALS AND METHODS: We report an incident learning system implementation customized for radiation therapy where any "unwanted or unexpected change from normal system behaviour that causes or has the potential to cause an adverse effect to persons or equipment" is reported, investigated and learned from. This system thus captures near-miss (potential) and actual events. Incidents are categorized according to severity, type and origin. RESULTS: Our analysis spans a period of 3 years with an average accrual of 11.6 incidents per week. We found a significant reduction in actual incidents of 28% and 47% in the second and third year when compared to the first year (p<0.001), which we attribute to the many interventions prompted by the analysis of incidents reported. We also saw a similar significant reduction in incidents generated at the treatment unit correlating with the introduction of direct treatment parameter transfer and electronic imaging (p<0.001). CONCLUSIONS: Implementation of an incident learning system has helped us to establish a just environment where all staff members report deviations from normal system behaviour and thus generate evidence to initiate safety improvements.

Long-term results of hypofractionated radiation therapy for breast cancer.

BACKGROUND: The optimal fractionation schedule for whole-breast irradiation after breast-conserving surgery is unknown. METHODS: We conducted a study to determine whether a hypofractionated 3-week schedule of whole-breast irradiation is as effective as a 5-week schedule. Women with invasive breast cancer who had undergone breast-conserving surgery and in whom resection margins were clear and axillary lymph nodes were negative were randomly assigned to receive whole-breast irradiation either at a standard dose of 50.0 Gy in 25 fractions over a period of 35 days (the control group) or at a dose of 42.5 Gy in 16 fractions over a period of 22 days (the hypofractionated-radiation group). RESULTS: The risk of local recurrence at 10 years was 6.7% among the 612 women assigned to standard irradiation as compared with 6.2% among the 622 women assigned to the hypofractionated regimen (absolute difference, 0.5 percentage points; 95% confidence interval [CI], -2.5 to 3.5). At 10 years, 71.3% of women in the control group as compared with 69.8% of the women in the hypofractionated-radiation group had a good or excellent cosmetic outcome (absolute difference, 1.5 percentage points; 95% CI, -6.9 to 9.8). CONCLUSIONS: Ten years after treatment, accelerated, hypofractionated whole-breast irradiation was not inferior to standard radiation treatment in women who had undergone breast-conserving surgery for invasive breast cancer with clear surgical margins and negative axillary nodes.

Interstitial brachytherapy in the management of persistent head and neck disease after definitive external beam radiation therapy.

PURPOSE: Persistent disease after definitive external beam radiation therapy for head and neck (H&N) malignancies negatively impacts survival. In this series, the effectiveness of low-dose-rate brachytherapy in the management of persistent H&N disease is explored. METHODS: All patients who received brachytherapy for persistent H&N disease between 1987 and 2002 were identified. Tumor and treatment characteristics and toxicities were recorded. Progression-free survival and overall survival estimates were generated. The influence of prognostic factors was determined. RESULTS: Twelve patients were analyzable. Brachytherapy was given curatively (n=4) in patients not amenable to surgery or in combination with surgical dissection to avoid carotid resection (n=8). Seven patients had disease progression with a median time to progression of 11 months (95% confidence interval: 0-22.9). The only negative prognostic factor was time to re-treatment (brachytherapy >4 months) after definitive treatment (p=0.003). Overall survival at 1 and 5 years was 50% and 21%, respectively. Toxicity was limited to one major complication (fistula) and five minor toxicities: low-grade radionecrosis (n=2), cellulitis (n=1), and wound dehiscence (n=2). CONCLUSION: In patients with persistent disease, brachytherapy is an appealing re-treatment alternative. When combined with neck dissection, brachytherapy yields less morbidity than the surgical alternative of carotid resection.

Brachytherapy and local excision for sphincter preservation in T1 and T2 rectal cancer.

PURPOSE: To report long-term results of brachytherapy after local excision (LE) in the treatment of T1 and T2 rectal cancer at risk of recurrence due to residual subclinical disease. METHODS AND MATERIALS: Between 1989 and 2007, 32 patients undergoing LE and brachytherapy were followed prospectively for a mean of 6.2 years. Estimates of local recurrence (LR), disease-specific survival (DSS), and overall survival (OS) were generated. Treatment-related toxicity and the effect of known prognostic factors were determined. RESULTS: There were 8 LR (3 T1, 5 T2), of which 5 were salvaged surgically. Median time to the 8 LR was 14 months, and the 5-year rate of local control was 76%. Although there have been 9 deaths to date, only 5 were from disease. Five-year DSS and OS rates were 85% and 78%, respectively. There were 4 cases of Grade 2-3 radionecrosis and 1 case of mild stool incontinence. The sphincter was preserved in 27 of 32 patients. CONCLUSION: Local excision and adjuvant brachytherapy for T1 and T2 rectal cancer is an appealing treatment alternative to immediate radical resection, particularly in the frail and elderly who are unable to undergo major surgery, as well as for patients wanting to avoid a permanent colostomy.

Radiation therapy in the management of the primary penile tumor: an update.

OBJECTIVES: Squamous carcinoma of the penis is rare but psychologically devastating and potentially fatal. Radiotherapy offers a penile-conserving treatment option without jeopardizing cure. We have used primary penile brachytherapy as the treatment of choice for T1, T2 and selected T3 patients since 1989 and present updated results for 67 patients. METHODS: Mean age was 60 years (range 22-93). Stage was T1 in 56%, T2: 33%, T3: 8%, and Tx: 3%. Grade was moderate or poorly differentiated in 48%. In Toronto after-loading pulse dose rate (PDR) brachytherapy (n = 41) was used for all treatments while Ottawa used manually loaded Iridium(192) (n = 26). Two or three parallel planes of needles (median 6) were inserted using pre-drilled lucite templates for guidance and fixation; 60 Gy was delivered over 4-5 days. RESULTS: Median follow-up is 4 years (range 0.2-16.2). At 10 years, actuarial overall survival is 59%, cause specific survival 83.6%. Nine men died of penile cancer and eight of other causes with no evidence of recurrence. Penectomy was required for eight local failures and two necroses, for an actuarial penile preservation rate at 5 years of 88% and 10 years of 67%. The soft tissue necrosis rate is 12% and the urethral stenosis rate 9%. Six of 11 regional failures were salvaged by lymph node dissection +/- external radiation. The other five all had concurrent distant failure and died of disease. CONCLUSIONS: Brachytherapy is an effective treatment for T1, T2 and selected T3 SCC of the penis. Close follow-up is mandatory as local failures and many regional failures can be salvaged by surgery.

Comparison of toxicity associated with early morning versus late afternoon radiotherapy in patients with head-and-neck cancer: a prospective randomized trial of the National Cancer Institute of Canada Clinical Trials Group (HN3).

PURPOSE: Based on our demonstration of a circadian rhythm in the human oral mucosa cell cycle, with most cells in the G(1) phase in the morning and M phase at night, we hypothesized that morning radiotherapy (RT) would lead to less oral mucositis than afternoon RT. METHODS AND MATERIALS: A total of 216 patients were randomized to morning (8-10 AM) vs. afternoon (4-6 PM) RT and stratified by radiation dose, smoking status, and center. Patients receiving primary or postoperative RT alone were eligible. Oral mucositis was scored using the Radiation Therapy Oncology Group (RTOG) criteria and a validated scoring system. RESULTS: Of 205 evaluable patients, 52.9% vs. 62.4% developed RTOG Grade 3 or greater mucositis after morning vs. afternoon RT, respectively (p = 0.17). Morning RT was also associated with significantly less weight loss after 5 months (p = 0.024). In a subgroup of 111 patients treated to a dose of 66-70 Gy in 33-35 fractions, exploratory analyses revealed a significant reduction in Grade 3 or greater mucositis with morning RT (44.6% vs. 67.3%, p = 0.022) and a longer interval to the development of Grade 3 or greater mucositis (median, >7.9 vs. 5.6 weeks, p = 0.033). In 53 patients, who smoked during therapy, a significant reduction was found in Grade 3 or greater mucositis with morning RT (42.9% vs. 76%, p = 0.025). CONCLUSION: In this proof of principle study, morning RT was associated with significantly less weight loss after 5 months and an apparent reduction in oral mucositis in a subset of patients receiving >/=66 Gy and in patients who smoked during therapy.

On-line rapid palliation using helical tomotherapy: a prospective feasibility study.

Rapid delivery of radiation therapy is expected to benefit patients requiring palliation. We investigated the feasibility of employing a helical tomotherapy unit to scan, plan, and deliver a radiation treatment in a single radiation therapy appointment. Eleven patients each had an MVCT scan acquired, a plan created, and delivery completed while the patient was on the treatment couch. Timelines for each step of the process were recorded for each patient, and compared with the conventional process for similar patients. Preliminary results show that patients routinely can be treated within a 1 hour appointment for the first fraction.

Brachytherapy in the retreatment of patients with new primary head and neck cancer.

OBJECTIVE: Re-treatment for cure of the Head and Neck (H&N) region is therapeutically challenging. In this review we explore the long-term results of Ir(192) low-dose-rate (LDR) brachytherapy in the select subgroup of patients treated for a new H&N malignancy. METHODS & MATERIAL: Thirteen patients received brachytherapy between 1987-2004 for a new primary H&N cancer, six of whom had been retreated previously. Brachytherapy was given as a monotherapy in eight patients and delivered adjuvantly in five patients. Three of the thirteen patients had advanced disease at the time of diagnosis. MAIN OUTCOME MEASURES: In addition to the known prognostic factors of stage and site, intent of brachytherapy and prior re-treatment status were assessed for their influence on local control (LC) and overall survival (OS). RESULTS: Local control differed by disease stage of the new primary tumor. With a median follow-up of 50 months, mean progression-free survival was 50.2 months [95%CI = 30.1-70.4] and the 2-year rate of LC was 58%. Adjuvant brachytherapy following surgery resulted in poor LC and OS due to advanced disease at diagnosis. Prior retreatment did not appear to affect LC or OS. OS at 2 and 5 years was 69% and 38%, respectively. There were no cases of grade III toxicity. CONCLUSIONS: LDR Brachytherapy for a new primary H&N cancer is a well-tolerated retreatment alternative that results in good local control. Our results suggest that the best chance for long-term survival remains in the routine follow-up and early diagnosis of the new H&N malignancy.

Interstitial low-dose-rate brachytherapy in the treatment of recurrent head and neck malignancies.

BACKGROUND: Recurrent head and neck malignancies are therapeutically challenging. Brachytherapy is a retreatment alternative to external-beam radiation therapy (EBRT). METHODS: Patients receiving brachytherapy during 1987-2004 for recurrent head and neck cancer were identified. Tumor and treatment characteristics and toxicities were recorded. Progression-free survival (PFS) and overall survival (OS) estimates were generated. The influence of prognostic factors was determined. RESULTS: Eighty-two patients were analyzable. Analysis was limited to patients who had brachytherapy for a first recurrence (n = 45). Brachytherapy (> or = 55 Gy) was a monotherapy in 22 of 45 patients. As part of their salvage brachytherapy treatments, 14 patients also underwent surgery; 3 patients also underwent EBRT; and 6 patients underwent surgery, EBRT, and brachytherapy. Retreatment morbidity included acute toxicity (n = 7) and late toxicity (n = 18). Median PFS was 15 months, and locoregional control rates at 1 and 2 years were 50% and 37%, respectively. Time to progression differed by site of the primary tumor (p = .10). Median OS was 16 months, and OS at 2 and 5 years was 33% and 11%, respectively. CONCLUSIONS: Brachytherapy for recurrent head and neck cancer has an acceptable toxicity profile and is viable alternative to EBRT. Further optimization of the best sites and doses for neck brachytherapy is required.

Vascular complications of cranial radiation.

OBJECTIVES: Cerebral vascular disease has been reported as a long-term complication of cranial radiotherapy. The purpose of this study was to examine the frequency and risk factors associated with development of cerebral vascular disease in children after cranial radiation. MATERIALS AND METHODS: A retrospective chart review of all cancer patients treated between 1985 and 2003 who were under the age of 18 years at the time of initial radiotherapy was performed. Variables examined include diagnosis and site of malignancy, age at the time of radiotherapy, sex, total radiation dosage, number of fractions, duration, and whether the patient had proven cerebral vascular event. RESULTS: Two hundred and forty-four patients met the study criteria. One hundred and 13 cases involved tumors of the central nervous system. The remaining patients had systemic neoplastic disease. Post radiation cerebral vascular disease occurred in 11 (5%) patients, and all but one patient had a tumor involving the central nervous system (mainly in the posterior fossa and supratentorial midline). CONCLUSION: There is an increased risk of cerebral vascular disease after radiation therapy in childhood, especially in children who received high dose radiation at the posterior fossa and supratentorial axial region.

Penile brachytherapy: results for 49 patients.

PURPOSE: To report results for 49 men with squamous cell carcinoma (SCC) of the penis treated with primary penile interstitial brachytherapy at one of two institutions: the Ottawa Regional Cancer Center, Ottawa, and the Princess Margaret Hospital, Toronto, Ontario, Canada. METHODS AND MATERIALS: From September 1989 to September 2003, 49 men (mean age, 58 years; range, 22-93 years) had brachytherapy for penile SCC. Fifty-one percent of tumors were T1, 33% T2, and 8% T3; 4% were in situ and 4% Tx. Grade was well differentiated in 31%, moderate in 45%, and poor in 2%; grade was unspecified for 20%. One tumor was verrucous. All tumors in Toronto had pulsed dose rate (PDR) brachytherapy (n = 23), whereas those in Ottawa had either Iridium wire (n = 22) or seeds (n = 4). Four patients had a single plane implant with a plastic tube technique, and all others had a volume implant with predrilled acrylic templates and two or three parallel planes of needles (median, six needles). Mean needle spacing was 13.5 mm (range, 10-18 mm), mean dose rate was 65 cGy/h (range, 33-160 cGy/h), and mean duration was 98.8 h (range, 36-188 h). Dose rates for PDR brachytherapy were 50-61.2 cGy/h, with no correction in total dose, which was 60 Gy in all cases. RESULTS: Median follow-up was 33.4 months (range, 4-140 months). At 5 years, actuarial overall survival was 78.3% and cause-specific survival 90.0%. Four men died of penile cancer, and 6 died of other causes with no evidence of recurrence. The cumulative incidence rate for never having experienced any type of failure at 5 years was 64.4% and for local failure was 85.3%. All 5 patients with local failure were successfully salvaged by surgery; 2 other men required penectomy for necrosis. The soft tissue necrosis rate was 16% and the urethral stenosis rate 12%. Of 8 men with regional failure, 5 were salvaged by lymph node dissection with or without external radiation. All 4 men with distant failure died of disease. Of 49 men, 42 had an intact and tumor-free penis at last follow-up or death. The actuarial penile preservation rate at 5 years was 86.5%. CONCLUSIONS: Brachytherapy is an effective treatment for T1, T2, and selected T3 SCC of the penis. Close follow-up is mandatory because local failures and many regional failures can be salvaged by surgery.
