Retroperitoneoscopic pre-transplant native kidney nephrectomy

INTERNATIONAL JOURNAL OF UROLOGY, Issue 4 2006
RAJIV GOEL
Aims:, Laparoscopic nephrectomy has become a standardized procedure for removal of benign non-functioning kidneys. We present our experience of retroperitoneoscopic pre-transplant native kidneys nephrectomy. Methods:, Comparison of 40 patients who underwent retroperitoneoscopy with 40 open simple pre-transplant nephrectomy patients was done. Results:, Forty retroperitoneoscopic nephrectomies were done between June 2003 and April 2005. The mean operative time was similar in the two groups; however, the mean blood loss, postoperative analgesic requirement, complication rate, hospital stay and convalescence period were significantly less in the retroperitoneoscopic group. Conclusion:, Retroperitoneoscopic nephrectomy should be offered as the primary treatment modality to patients requiring pre-transplant native kidney nephrectomy, except in patients where it is contraindicated.

Primary Treatment of Ranula With Intracystic Injection of OK-432

THE LARYNGOSCOPE, Issue 2 2006
Jong-Lyel Roh MD
Abstract Objective: Although surgery is the first choice of therapy for ranula, it was made a hypothesis that ranula can be primarily treated with sclerotherapy from prior evidence. This study examined the effectiveness of intracystic injection of OK-432 for treatment of ranula. Method: This prospective clinical study comprised a total of 26 patients with ranula (19 intraoral type; seven plunging type) treated with OK-432 sclerotherapy. Aspirated mucus of ranula was replaced with an equal volume of OK-432 solution of 0.01 mg/mL. The size of ranula was compared before and after sclerotherapy. Results: Twenty of 26 patients (77%) showed a complete response after sclerotherapy: higher in plunging ranula (86%) than in intraoral ranula (74%). Rupture of ranula developed in seven of 19 patients (37%) with intraoral ranula within a few days after injection. The early rupture occurred more frequently in patients having a less-than-marked response and seemed to cause an increase in the total number of OK-432 injections: seven ruptured cases versus 12 nonruptured cases (mean 3.6 versus 1.5, P < .001). Recurrence occurred in two patients during a median follow-up period of 12 months (range, 9,22 mo) after the last injection. There were no major side effects, scarring, or increased morbidity to surgery of the OK-432-injected lesions. Conclusion: The intracystic injection of OK-432 is highly effective as a primary treatment modality of ranula. [source]

Complications of radiotherapy in laryngopharyngeal cancer,

Effects of a prospective smoking cessation program
Abstract BACKGROUND: Radiotherapy (XRT) is effective as the primary treatment modality for laryngopharyngeal cancer; however, complications of XRT can result in significant morbidity. Few previous studies have examined the effect of continued smoking on complications of XRT. The authors of this report hypothesized that patients with laryngopharyngeal cancer who successfully quit smoking would have fewer complications of primary XRT. METHODS: All patients with head and neck cancer who were smokers at the time of diagnosis were referred prospectively to the Tobacco Treatment Program (TTP). From this group, the patients with laryngopharyngeal cancer who received XRT as the primary treatment modality were retrospectively selected and studied. RESULTS: Eighty-six patients were identified and were divided into 3 groups: Seventeen patients attended TTP and quit smoking before the start of XRT (Group 1), 33 patients attended TTP but continued to smoke during XRT (Group 2), and 37 patients refused TTP (Group 3). On the basis of a review of medical records for patients in Group 3, 20 patients quit smoking before starting XRT and were included in Group 1 (abstainers), 11 patients continued to smoke and were included in Group 2 (continued smokers), and 6 patients had incomplete data and were omitted from further analysis. Analyses both with and without Group 3 patients yielded similar results. Abstainers and continued smokers had similar demographic and clinical characteristics. With the exception of skin changes, all complications (mucositis, need for feeding tube, duration of feeding tube, need for hospitalization, pharyngeal stricture, and osteoradionecrosis) were more common in the patients who continued to smoke, although the only complications that were significantly more common were the need for hospitalization (P = .04) and osteoradionecrosis (P = .03). Patients who continued to smoke were more likely to develop osteoradionecrosis (relative risk [RR], 1.32; 95% confidence interval [CI], 1.09-1.6; P = .03) and to require hospitalization during treatment (RR, 1.46; 95% CI, 1.05-2.02; P = .04). CONCLUSIONS: Continued smoking during treatment appeared to increase the risk for complications of XRT for patients with laryngopharyngeal cancer and possibly increased hospitalizations. This hypothesis-generating study emphasized the importance of smoking cessation programs in the management of patients with head and neck cancer patients who receive XRT.

Radiosurgery for the treatment of spinal lung metastases

CANCER, Issue 11 2006
Peter C. Gerszten MD
Abstract BACKGROUND. Spinal metastases are a common source of pain as well as neurologic deficit in patients with lung cancer. Metastases from lung cancer traditionally have been believed to be relatively responsive to radiation therapy. However, conventional external beam radiotherapy lacks the precision to allow delivery of large single-fraction doses of radiation and simultaneously limit the dose to radiosensitive structures such as the spinal cord. The current study evaluated the efficacy of single-fraction radiosurgery for the treatment of spinal lung cancer metastases. METHODS. In the current prospective cohort evaluation, 87 lung cancer metastases to the spine in 77 patients were treated with a single-fraction radiosurgery technique with a follow-up period of 6 to 40 months (median, 12 months). The indication for radiosurgery treatment was pain in 73 cases, as a primary treatment modality in 7 cases, for radiographic tumor progression in 4 cases, and for progressive neurologic deficit in 3 cases. RESULTS. Tumor volume ranged from 0.2 to 264 cm3 (mean, 25.7 cm3). The maximum tumor dose was maintained at 15 to 25 grays (Gy) (mean, 20 Gy; median, 20 Gy). No radiation-induced toxicity occurred during the follow-up period. Long-term axial and radicular pain improvement occurred in 65 of 73 patients (89%) who were treated primarily for pain. Long-term radiographic tumor control was observed in all patients who underwent radiosurgery as their primary treatment modality or for radiographic tumor progression. CONCLUSIONS. Spinal radiosurgery was found to be feasible, safe, and clinically effective for the treatment of spinal metastases from lung cancer. The results of the current study indicate the potential of radiosurgery in the treatment of patients with spinal lung metastases, especially those with solitary sites of spine involvement, to improve long-term palliation.

Single-fraction radiosurgery for the treatment of spinal breast metastases

CANCER, Issue 10 2005
M.P.H., Peter C. Gerszten M.D.
Abstract BACKGROUND The spine is the most common site of bony metastases in patients with osseous breast carcinoma metastases. Spine metastases are the source of significant pain and occasionally neurologic deficit in this patient population. Conventional external beam radiotherapy lacks the precision to allow delivery of large single-fraction doses of radiation and simultaneously limit the dose to radiosensitive structures such as the spinal cord. This study evaluated the clinical efficacy of the treatment of spinal breast carcinoma metastases with a single-fraction radiosurgical technique. METHODS In this prospective cohort evaluation, 68 breast carcinoma metastases to the spine in 50 patients were treated with a single-fraction radiosurgery technique with a follow-up period of 6,48 months, median 16 months. The most common indication for radiosurgery treatment was pain in 57 lesions, as a primary treatment modality in 8 patients, and for radiographic tumor progression, as a postsurgical boost, and for a progressive neurologic deficit in 1 patient each. RESULTS Tumor volume ranged from 0.8,197 cm3 (mean, 27.7 cm3). Maximum tumor dose was maintained at 15,22.5 Gy (mean, 19 Gy). No radiation-induced toxicity occurred during the follow-up period (6,48 mo). Long-term axial and radicular pain improvement occurred in 55 of 57 (96%) patients who were treated primarily for pain. Long-term radiographic tumor control was seen in all patients who underwent radiosurgery as their primary treatment modality, for radiographic tumor progression, or as a postsurgical treatment. CONCLUSIONS Spinal radiosurgery was found to be feasible, safe, and clinically effective for the treatment of spinal metastases from breast carcinoma. The results indicate the potential of radiosurgery in the treatment of patients with spinal breast metastases, especially those with solitary sites of spine involvement, to improve long-term palliation.
