Effective treatment of anal cancer in the elderly with low-dose chemoradiotherapy

Chemoradiotherapy (CRT) is accepted as the standard initial treatment for squamous cell anal cancer. However, frail elderly patients cannot always tolerate full-dose CRT. This paper reports the results of a modified regimen for this group of patients. In all, 16 patients with biopsy-proven squamous cell carcinoma of the anal canal or margin and performance status or co-morbidity precluding the use of full-dose CRT were included in this protocol. The median age was 81 (range 77–91). Patients received a dose of 30 Gy to the gross tumour volume plus 3 cm margin in all directions. Concurrent chemotherapy comprised 5-fluorouracil 600 mg m−2 given over 24 h on days 1–4 of radiotherapy. The treatment was well tolerated. All 16 patients completed treatment as planned. Only one patient experienced any grade 3 toxicity (skin). The local control at a median follow-up of 16 months was 73% (13 out of 16). The overall survival was 69% and disease-specific survival 86%. This is a well-tolerated regimen for elderly/poor performance patients with anal cancer, which can achieve high rates of local control and survival. Longer follow-up will determine whether these encouraging results are maintained

Chemoradiotherapy with or without consolidation chemotherapy using cisplatin and 5-fluorouracil in anal squamous cell carcinoma: long-term results in 31 patients

<p>Abstract</p> <p>Background</p> <p>The objectives of this study were to evaluate long-term results of concurrent chemoradiotherapy (CRT) with 5-fluorouracil and cisplatin and the potential benefit of consolidation chemotherapy in patients with anal squamous cell carcinoma (ASCC).</p> <p>Methods</p> <p>Between January 1995 and February 2006, 31 patients with ASCC were treated with CRT. Radiotherapy was administered at 45 Gy over 5 weeks, followed by a boost of 9 Gy to complete or partial responders. Chemotherapy consisted of 5-fluorouracil (750 or 1,000 mg/m²) daily on days 1 to 5 and days 29 to 33; and, cisplatin (75 or 100 mg/m²) on day 2 and day 30. Twelve patients had T3–4 disease, whereas 18 patients presented with lymphadenopathy. Twenty-one (67.7%) received consolidation chemotherapy with the same doses of 5-fluorouracil and cisplatin, repeated every 4 weeks for maximum 4 cycles.</p> <p>Results</p> <p>Nineteen patients (90.5%) completed all four courses of consolidation chemotherapy. After CRT, 28 patients showed complete responses, while 3 showed partial responses. After a median follow-up period of 72 months, the 5-year overall, disease-free, and colostomy-free survival rates were 84.7%, 82.9% and 96.6%, demonstrating that CRT with 5-fluorouracil and cisplatin yields a good outcome in terms of survival and sphincter preservation. No differences in 5-year OS and DFS rates between patients treated with CRT alone and CRT with consolidation chemotherapy was observed.</p> <p>Conclusion</p> <p>our study shows that CRT with 5-FU and cisplatin, with or without consolidation chemotherapy, was well tolerated and proved highly encouraging in terms of long-term survival and the preservation of anal function in ASCC. Further trials with a larger patient population are warranted in order to evaluate the potential role of consolidation chemotherapy.</p

Quality of life and tumor control after short split-course chemoradiation for anal canal carcinoma

<p>Abstract</p> <p>Purpose</p> <p>To evaluate quality of life (QOL) and outcome of patients with anal carcinoma treated with short split-course chemoradiation (CRT).</p> <p>Methods</p> <p>From 1991 to 2005, 58 patients with anal cancer were curatively treated with CRT. External beam radiotherapy (52 Gy/26 fractions) with elective groin irradiation (24 Gy) was applied in 2 series divided by a median gap of 12 days. Chemotherapy including fluorouracil and Mitomycin-C was delivered in two sequences. Long-term QOL was assessed using the site-specific EORTC QLQ-CR29 and the global QLQ-C30 questionnaires.</p> <p>Results</p> <p>Five-year local control, colostomy-free survival, and overall survival were 78%, 94% and 80%, respectively. The global QOL score according to the QLQ-C30 was good with 70 out of 100. The QLQ-CR29 questionnaire revealed that 77% of patients were mostly satisfied with their body image. Significant anal pain or fecal incontinence was infrequently reported. Skin toxicity grade 3 or 4 was present in 76% of patients and erectile dysfunction was reported in 100% of male patients.</p> <p>Conclusions</p> <p>Short split-course CRT for anal carcinoma seems to be associated with good local control, survival and long-term global QOL. However, it is also associated with severe acute skin toxicity and sexual dysfunction. Implementation of modern techniques such as intensity-modulated radiation therapy (IMRT) might be considered to reduce toxicity.</p

Tratamento com radio e quimioterapia do carcinoma epidermóide do canal anal: experiência do hospital Barão de Lucena Radiochemotherapy for squamous cell carcinoma of the anal canal: Barao de Lucena hospital experience

Objetivos: Apresentar os resultados e analisar as variáveis implicadas no tratamento e prognóstico do carcinoma epidermóide do canal anal tratado através da radio e quimioterapia no Hospital Barão de Lucena-SUS-PE. Metodologia: Análise dos prontuários de pacientes com diagnóstico de câncer do canal anal submetidos a tratamento radioquimioterápico. O período de acompanhamento foi de junho de 1989 a junho de 2005. Foram incluídos os pacientes com diagnóstico histológico de câncer de canal anal, enquadrados nos estadios I, II, IIIa e IIIb, submetidos a dois ciclos de quimioterapia com 5-fluorouracil (5-FU) na dose de 1g/m²/dia em infusão contínua de 96 horas e cisplatino na dose de 100mg/m² administrado em 6 horas no segundo dia de infusão de cada ciclo, administrados na primeira e terceira semanas do esquema de tratamento radioterápico. Resultados: Avaliamos 108 prontuários de pacientes que preencheram os critérios do protocolo. O tempo médio de seguimento foi de 51 meses (1-182 meses). Houve predomínio do gênero feminino (81,5% dos pacientes). A idade variou de 33 a 83 anos (média de 59 anos). O tipo histológico mais freqüente foi o carcinoma de células escamosas (80,6% dos casos). Em 21 pacientes, foi diagnosticado carcinoma basalóide. Quanto ao grau de diferenciação, prevaleceu o tipo moderadamente diferenciado (61% dos pacientes com carcinoma de células escamosas). O índice de resposta inicial completa foi de 89,8%. Onze pacientes persistiram com tumor após o tratamento radio e quimioterápico. O índice de resposta inicial completa foi menor nos estadios IIIa e IIIb em relação aos estadios I e II com significância estatística (p<0,05). 14 pacientes evoluíram com recidiva tumoral, oito com recidiva local (7,4%) e seis (5,5%) com recidiva linfática e à distância. CONCLUSÕES: O tratamento radioquimioterápico exclusivo do carcinoma epidermóide do canal anal, tem índice de resposta completo bastante elevado com morbidade aceitável. O tratamento cirúrgico ainda tem seu valor nos casos de persistência da lesão e/ou de recidiva local, com resultados satisfatórios.<br>Objectives: To present the results and analyze the variables involved in the treatment and prognosis of squamous cell carcinoma of the anal canal treated by radiotherapy and chemotherapy at the Hospital Barao de Lucena-SUS-PE. Methodology: Analysis of medical records of patients diagnosed with anal cancer treated by chemoradiation. The monitoring period was from June 1989 to June 2005. We included patients with histologically confirmed cancer of the anal canal, framed in stages I, II, IIIa and IIIb, underwent two cycles of chemotherapy with 5-fluorouracil (5-FU) at a dose of 1g / m² / day continuous infusion 96 hours and cisplatin at a dose of 100 mg / m² administered at 6 hours the second day of infusion of each cycle, administered on the first and third weeks of radiotherapy treatment regimen. Results: We evaluated records of 108 patients who met the criteria of the protocol. The mean follow-up was 51 months (1-182 months). There were more females (81.5% of patients). The age ranged from 33 to 83 years (mean 59 years). The most common histological type was squamous cell carcinoma (80.6% of cases). In 21 patients, was diagnosed Basaloid carcinoma. Regarding the degree of differentiation, the most prevalent type was moderately differentiated (61% of patients with squamous cell carcinoma). The rate of initial complete response was 89.8%. Eleven patients had persistent tumor after radiotherapy and chemotherapy. The initial response rate was lower in complete stages IIIa and IIIb compared to stages I and II with statistical significance (p <0.05). 14 patients developed recurrence, eight with local recurrence (7.4%) and six (5.5%) with lymphatic recurrence and distance. CONCLUSIONS: The chemoradiation treatment of unique cell carcinoma of the anal canal, have complete response rate very high with acceptable morbidity. Surgical treatment still has its value in cases of persistent injury and / or local recurrence, with satisfactory results
