AIM: To study the efficacy of an organ-preserving, sequential chemoradiation therapy for squamous cell carcinoma of the anal canal, and of salvage surgery in those in whom this treatment fails. METHODS: Forty biopsy-proven untreated patients (28 men) with squamous cell carcinoma of the anal canal received two cycles of chemotherapy using cisplatin and methotrexate, followed by 45 to 60 (median 50) Gy external beam radiotherapy. Salvage surgery was offered to those in whom this treatment failed. Overall survival, disease-free survival and colostomy-free survival were analyzed. RESULTS: Most patients (n=35; 87%) had T3 or T4 lesions and 5 (12.5%) had involvement of inguinal nodes. Thirty-one patients (77.5%) had complete response after chemoradiation. Only three patients (7.5%) developed chemotherapy-related grade 3 mucositis and myelosuppression. Radiotherapy-related toxicity included grade III cystitis in one patient and grade III proctitis in three patients. Three patients had post-treatment anal stenosis requiring repeated dilatation and two had chronic non-healing ulcers at the anal verge. Nine patients had failure of chemoradiation or disease recurrence; of these, only 5 could undergo salvage surgery. After a median follow up of 60 months, overall survival, disease-free survival and colostomy-free survival were 80%, 77.5% and 72.5%, respectively. CONCLUSION: Chemoradiation is effective in the treatment of squamous cell anal cancer and has acceptable toxicity. Surgical salvage may be useful in those with failure of this treatment.
Despite improvement in the diagnostic modalities, surgical technique, chemotherapy and radiotherapy, mortality and morbidity due to carcinoma esophagus continues to be dismal. Combination of external and intraluminal radio therapy (ILRT) has emerged as a powerful and promising palliative therapy in this disease. Thirty four patients with inoperable cancer esophagus treated with ILRT during June 1991 to December 1993 were evaluated to assess its palliative effects. Seventeen of these patients had received additional chemotherapy and external radiotherapy. Thirteen patients received only radiotherapy (both external radiotherapy + ILRT) and the remaining 4 received only ILRT. They were followed up for a mean period of 8.3 months (range 2 to 28 months) during which one patient was lost to follow up. Eight had a follow up of less than 6 months. Eight (33%) amongst the remaining 25 patients were considered disease free, 15 had recurrent and progressive disease, one developed metastasis and one patient died. In 21 (66%) dysphagia markedly improved. Nine (26%) patients survived beyond 1 year and the median survival for all patients was 8 months. Associated radiation morbidity was documented in 13 (38%) patients. We conclude that combination of external radiotherapy and ILRT is an effective and safe therapy for inoperable esophageal malignancies.
Generalised peritonitis is a common and dreaded surgical emergency. Its tropical spectrum continues to be different from its western counterpart. The study represents a retrospective analysis of 250 cases of peritonitis managed surgically over a decade at a large referral surgical unit at New Delhi. Perforations of the upper gastrointestinal tract viz: duodenal ulcer, enteric perforations etc. constitute the majority unlike western series where lower gastrointestinal tract perforations predominate. Despite significant delays in presentation, the overall prognosis remains comparable to the western figures. A comparatively younger age group involved may be responsible for better outcome.
From January 1993 to December 1995, complete records of patients with biliary neoplasms were analysed. A total of 124 patients were registered. Majority of patients were in the age range of 40-60 years (median 54 years). There were 38 males and 86 females. Histopathologically, adenocarcinoma was the commonest type (59%). Pain, jaundice and lump were noticed in 119, 54 and 77 patients respectively. Fifty six patients had associated gall stones. Ninety patients had metastatic disease at presentation. Majority of them (110/124) had advanced, inoperable disease and therefore were considered for palliative treatment. Only 14 patients (12%) were considered for curative treatment. Of these 14 patients, all the cases underwent surgery, 10 received radiotherapy and 10 received chemotherapy. Follow up was very poor. The survival of 14 patients, who received curative treatment, ranged from 2 months to 44 months with mean of 16 months.
