Parotid gland masses: outcomes in the pediatric age group.

Background: Childhood parotid neoplasms appear to have different characteristics from adults. This point, in addition to the rarity of these tumors, reflects the challenges faced in diagnosing and treating parotid neoplasms in children.

Patients And Methods: This retrospective study included all children who presented to the Children's Cancer Hospital Egypt (CCHE, 57357) with parotid masses from January 2008 to December 2020.

Locally advanced rectal carcinoma: preoperative radiotherapy versus postoperative chemoradiation, 10-year follow-up results of a randomized clinical study.

Purpose: A prospective study was designed to randomize locally advanced rectal carcinoma patients between either preoperative radiotherapy (+/- postoperative chemotherapy) or postoperative adjuvant chemoradiation. Two end points were evaluated, local recurrence and survival, aiming at defining prognostic parameters that can help in the choice of the optimum treatment modality.

Patients And Methods: This is a prospective randomized clinical study including patients with locally advanced low rectal cancer treated at the National Cancer Institute (NCI), Cairo University, during the period from December 1994 to January 1999.

Bone metastases in muscle-invasive bladder cancer.

Purpose: To address the necessity of incorporating isotopic bone scan in the routine staging work-up of muscle invasive bladder cancer patients, we analyzed the data in our files to determine the incidence of bone metastasis in such patients. The rate of subsequent development of bone metastasis along the natural history of the disease was also investigated.

Patients And Methods: A total of 179 files of consecutive bladder cancer patients who presented to the National Cancer Institute, Cairo University, between January 2000 and December 2001 were reviewed to check the percentage of positive bone scans on presentation and to check the subsequent development of distant metastases and bone metastasis in these patients' records.

Hypofractionation versus conventional fractionation radiotherapy after conservative treatment of breast cancer: early skin reactions and cosmetic results.

Purpose: To compare in a prospective trial the acute skin reaction and late cosmetic effects of normal fractionation versus hypofractionation radiotherapy after breast conserving surgery.

Patients And Methods: Thirty patients with T 1-2N0M0 breast cancer who underwent breast conserving surgery (BCS) were included in the study. Half of the patients received whole breast irradiation, consisting of 50 Gy/25f/5w+boost 10Gy/5f/1w to tumor bed (group A).
