Radiotherapy for node positive penile cancer: experience of the Leeds teaching hospitals.

PURPOSE: We studied the outcomes in patients with node positive penile cancer who received radiotherapy to inguinal and pelvic nodes. Although half of node positive cases are cured by lymphadenectomy, little data are available on the potential further benefits and toxicities of postoperative radiotherapy. MATERIALS AND METHODS: We retrospectively audited the clinical notes and electronic records of 23 patients referred to a specialist center from 2002 to 2008 who received radiotherapy to the inguinal/pelvic nodes as adjuvant treatment after lymphadenectomy (14), or as high grade palliation for extensive/fixed nodes (8) or extensive local tumor (1). The primary outcome measure was overall survival. Secondary end points were locoregional recurrence-free survival and toxicity. RESULTS: All 13 deaths were due to penile cancer. Patients with adjuvant therapy had better overall survival (66% vs 11%, p<0.001) and locoregional relapse-free survival (56% vs 22%, p=0.03) than those with high grade palliation. Six of 14 adjuvant cases and 7 of 9 with high grade palliation relapsed locoregionally. Of patients with adjuvant therapy and extracapsular spread 1 of 6 with N1, 1 of 4 with N2 and 3 of 4 with N3 disease relapsed (p=0.31). No life threatening toxicity was observed. It was difficult to determine the relative contributions of radiotherapy and surgery to leg/scrotal lymphedema. The study was limited by its small size, which reflects the rarity of this tumor. CONCLUSIONS: Adjuvant radiotherapy appears to have a role after inguinal lymphadenectomy, particularly in patients with extracapsular nodal spread, in whom historically survival rates have been poor. Our findings warrant further investigation in larger series of patients.

Ten-year longitudinal health-related quality of life following iodine-125 brachytherapy monotherapy for localized prostate cancer.

PURPOSE: This prospective longitudinal study quantifies health-related quality of life (HRQoL) up to 10 years following permanent iodine-125 (125I) prostate brachytherapy alone for localized prostate cancer. MATERIAL AND METHODS: In total, 120 patients completed a validated expanded prostate cancer index composite (EPIC) questionnaire pre-treatment and at 8 time points after treatment (6 weeks, 6, 10, 18 months, and 2, 3, 5, 10 years). At each time point, clinically relevant small, moderate, and severe declines in HRQoL were defined as 0.2-0.5 SD, 0.5-0.8 SD, and > 0.8 SD of baseline function for each of urinary, bowel, and sexual domains, respectively. RESULTS: Response rates in the first two years were > 90%, but thereafter dropped to 75% and 48% at 5 and 10 years, respectively. 50 patients (41.6%) responded at all stages. Maximal deterioration in mean urinary and sexual summary scores was noted 6 weeks after implant, with severe urinary symptoms and moderate bowel/sexual symptoms. At 6 months, urinary and bowel quality of life (QoL) had improved to mild impairment, which then fully resolved at 10 months. Sexual QoL remained mildly impaired throughout the 10 years of follow-up. At 10 years, new mild impairment of urinary and bowel QoL was found. CONCLUSIONS: Clinically mild changes in urinary, bowel, and sexual QoL are found 10 years after 125I monotherapy. The impairment in sexual function persists from treatment, but urinary and bowel symptoms are new at 10 years.

Impact of prophylactic gastrostomy or reactive NG tube upon patient-reported long term swallow function following chemoradiotherapy for oropharyngeal carcinoma: A matched pair analysis.

OBJECTIVES: The purpose of this matched pair analysis is to assess patient-reported long term swallow function following chemoradiotherapy for locally advanced oropharyngeal cancer in relation to the use of a prophylactic gastrostomy or reactive nasogastric (NG) tube. MATERIALS AND METHODS: The MD Anderson Dysphagia Inventory (MDADI) was posted to 68 consecutive patients with stage III/IV oropharyngeal squamous cell carcinoma who had completed parotid sparing intensity modulated radiotherapy with concurrent chemotherapy between 2010 and 2012, had not required therapeutic enteral feeding prior to treatment, minimum 2years follow up post treatment, and who were disease free. 59/68 replies were received, and a matched pair analysis (matching for T and N stage) was performed for 52 patients, 26 managed with a prophylactic gastrostomy and 26 with an approach of an NG tube as needed. RESULTS: There were no significant differences in patient demographics, pre-treatment diet and treatment factors between the two groups. Patient-reported swallowing function measured using the MDADI was superior for patients managed with an NG tube as required compared with a prophylactic gastrostomy: overall composite score 68.1 versus 59.4 (p=0.04), global score 67.7 versus 60 (p=0.04), emotional subscale 73.5 versus 60.4 (p<0.01), functional subscale 75.4 versus 61.7 (p<0.01), and physical subscale 59.6 versus 57.1 (p=0.38). CONCLUSIONS: Compared with an approach of an NG tube as required, the use of a prophylactic gastrostomy was associated with inferior long term patient-reported long term swallow outcomes.
