TH Khor
Summary The aim of this is to report the results of radical radiotherapy in carcinoma of the cervix treated by high-dose rate (HDR) intracavitary brachytherapy and external beam radiotherapy (XRT) at a single centre in Singapore. This is a retrospective analysis of 106 consecutive cases with histologically proven cervical cancer, treated by HDR brachytherapy and XRT at the Mount Elizabeth Hospital from 1990 to 1993. External beam radiotherapy to the pelvis was delivered with 6 MV photons, to 45,50.4 Gy in 1.8 Gy fractions. High-dose-rate brachytherapy comprised two to three applications of an intrauterine tandem with paired ovoids, to a median dose of 18 Gy to point ,A', carried out during XRT. All 106 patients completed treatment. Their ages ranged from 32 to 80 years (median 57 years). Most patients presented with stage II or III disease (44 and 37%, respectively) and with squamous cell carcinoma (91%). Median follow-up time was 59 months (range 2,169 months). The 5-year relapse-free survival rate across all stages was 71%. The corresponding overall survival rate was 69%. Local control was achieved in 86 patients (81%); six patients had residual disease (6%), and 14 patients had local recurrence (13%). Fourteen patients developed metastatic disease (13%). On univariate analysis, tumour stage, haemoglobin level, number of brachytherapy treatments and overall treatment time were found to be prognostic factors for overall survival. Late complications were mild (Radiation Therapy Oncology Group score 1,2), except for one patient with grade 4 rectal toxicity. The complication rates were 8, 14 and 45%, respectively, for the rectum, bladder and vagina (stenosis). The use of two to three fractions of HDR intracavitary brachytherapy in addition to pelvic XRT achieves good outcomes. [source]

Abstract Background. Supracricoid laryngectomy with cri-cohyoidoepiglottopexy (CHEP) is a conservative surgical procedure indicated in selected cases of advanced glottic carcinoma. Methods. This study is a review of our experience with 43 patients with T3/T4 glottic squamous cell carcinoma who underwent CHEP in our institution. All but two patients underwent selective neck dissections. All patients were staged on the basis of the 2002 TNM classification. Rates of recurrence and death were estimated by the Kaplan,Meier method. Results. The 5-year disease-specific survival and 5-year relapse-free survival rates were 78% and 83%, respectively. Neck metastases were found in three patients. Cartilage invasion occurred in 11 cases. The average length of hospital stay was 5.7 days. The mean time of enteral feeding tube was 33.8 days, and the mean time for tracheotomy was 29.6 days. Overall, normal swallowing was achieved in 74.4% of patients. Eleven patients had mild and major complications. Laryngeal stenosis emerged as the most frequent major complication. Three patients (6.9%) had local recurrences. Two patients (4.6%) had neck metastases. Conclusions. On the basis of this study, over a 7-year period with 43 patients with advanced glottic cancer, a successful on-cologic outcome is confirmed. © 2006 Wiley Periodicals, Inc.

Polyclonal anti-T-cell globulin as part of the preparative regimen for pediatric allogeneic stem-cell transplantation

PEDIATRIC TRANSPLANTATION, Issue 4 2001

Abstract: To prevent graft rejection and graft-versus-host disease (GvHD) after allogeneic stem-cell transplantation (ASCT), 56 children were given polyclonal anti-T-cell globulin (ATG) as part of the conditioning regimen. Of the 56 children in the cohort, 27 had a non-malignant disease and 29 had different hematological malignancies. Eight were in first remission of leukemia and the remainder in later stages. Donors were in 16 cases a human leucocyte antigen (HLA)-identical sibling and in 40 a matched unrelated donor (MUD). The control group comprised 16 patients with an HLA-identical donor; the children in this group were not treated with ATG. Side-effects related to the ATG treatment occured in 63% of the patients and included fever, chills, headache, dyspnoea, nausea/vomiting, body pain, fall in blood pressure, and transient respiratory arrest. Engraftment occured in 55 (98%) of the ATG-treated patients at a median of 17 (11,27) days after ASCT. One rejection occured at 23 days post-SCT. The probabilities of acute graft-versus-host disease (GvHD) of grades II,IV were 6% for patients with an HLA-identical donor, 12% for controls, and 26% for the MUD group. Chronic GvHD occured in 20%, 50%, and 50% of patients in the three groups, respectively. Transplant-related mortality rates at 100 days were 6%, 6%, and 7%, respectively. The 5-yr survival rate was 94% and 81% using sibling donors, with and without ATG respectively, and 53% using unrelated donors (p =,0.002). Disregarding donor type, among the ATG-treated patients 5-yr survival rates were 46% in patients with a malignant disease and 77% in non-malignant disorders. Relapse and relapse-free survival rates were 42% and 46%, respectively. Five out of 12 patients who showed an early full donor chimerism in the T-cell lineage developed acute GvHD of grades II,IV, compared to none out of 13 patients being mixed chimeras (p =,0.01). Hence, the use of polyclonal ATG as part of conditioning prior to ASCT in children is safe and the survival rate encouraging. [source]


Clinical features and outcomes in 348 patients with polyarteritis nodosa: A systematic retrospective study of patients diagnosed between 1963 and 2005 and entered into the French vasculitis study group database

Objective Previous studies of polyarteritis nodosa (PAN) included patients with microscopic polyangiitis, because these entities were not distinguished prior to the Chapel Hill Consensus Conference (CHCC). This study was undertaken to describe the main characteristics of and long-term outcomes in patients with well-characterized PAN diagnoses. Methods We conducted a systematic retrospective study of 348 patients who were diagnosed as having PAN between March 1963 and October 2005, were registered in the French Vasculitis Study Group database, and satisfied the American College of Rheumatology and CHCC criteria. Patient characteristics and outcomes were analyzed and compared according to hepatitis B virus (HBV) status. Results At diagnosis, the mean ± SD age was 51.2 ± 17.3 years. The most frequent findings were general symptoms (93.1%), neurologic manifestations (79%), skin involvement (49.7%), abdominal pain (35.6%), and hypertension (34.8%); 66.2% had renal artery microaneurysms; 70.1% had histologically proven PAN. Patients with HBV-related PAN (n = 123) had more frequent peripheral neuropathy, abdominal pain, cardiomyopathy, orchitis, and hypertension compared with patients with non,HBV-related PAN (n = 225). During a mean ± SD followup of 68.3 ± 63.5 months, 76 patients (21.8%) relapsed (63 with non,HBV-related PAN [28%] versus 13 with HBV-related PAN [10.6%]; P < 0.001); 86 patients (24.7%) died (44 with non,HBV-related PAN [19.6%] versus 42 with HBV-related PAN [34.1%]; P = 0.003). Five-year relapse-free survival rates were 59.4% (95% confidence interval [95% CI] 52.6,67.0) versus 67.0% (95% CI 58.5,76.8) for non,HBV-related PAN and HBV-related PAN, respectively. Multivariate analysis retained age >65 years, hypertension, and gastrointestinal manifestations requiring surgery or at least consultation with a surgeon as independent predictors of death, whereas patients with cutaneous manifestations or non,HBV-related PAN had a higher risk of relapse. Conclusion Our findings indicate that the rate of mortality from PAN remains high, especially for the elderly, and relapses do occur, particularly in patients with non,HBV-related PAN with cutaneous manifestations.
