Introduction: Chylothorax is by definition a collection of lymphatic fluids in the pleural cavity because of leakage from main thoracic duct or its tributaries. It is an uncommon but serious postoperative complication in esophageal cancer patients. There is no standard therapeutic algorithm for chylothorax because no prospective or randomized trials have yet been performed to evaluate the available treatment options.

Background: Surgical resection of the abnormal parathyroid glands is the only curative treatment for primary hyperparathyroidism (PHPT). Radioguided parathyroidectomy with technetium-99m (TC-99m) sestamibi has been successfully used in patients with PHPT. This study was designed to evaluate the results of a series of patients with PHPT who underwent minimally invasive radioguided parathyroidectomy (MIRP) using very low dose (1 mCi) of TC-99m sestamibi (MIBI) without application of intraoperative parathyroid hormone (PTH) assay or frozen section analysis.

Introduction: In the current study, we evaluated the accuracy of sentinel node mapping in thyroid cancer patients using both radiotracer and blue dye.

Material And Methods: 30 patients with a diagnosis of papillary thyroid carcinoma (PTC) were included in the study; 2-3 hours before surgery, 0.5 mCi 99m-Tc-Antimony Sulfide Colloid was injected intra-tumourally.

Sentinel node biopsy can decrease the morbidity of breast cancer treatment significantly by sparing many patients of axillary lymph node dissection and resulting arm lymphedema. Despite widespread use of sentinel node mapping for breast cancer patients almost all aspects of this procedure are controversial; such as: type of the radiotracer, eligibility, time of injection, etc. One of these controversial issues is the efficacy of 2 days protocol (injection of the tracer on one day and sentinel node mapping and surgery on the following day).

Despite the successful application of sentinel node mapping in breast cancer patients, its use in patients with a history of previous excisional biopsy of the breast tumors is a matter of controversy. In the present study we evaluated the accuracy of sentinel node biopsy in this group of patients and compared the results with those in whom the diagnosis of breast cancer was established by core needle biopsy. Eighty patients with early stage breast carcinoma were included into our study.

Objective: We compared early and delayed lymphoscintigraphy images using intradermal injection of (99m)Tc-antimony sulfide colloid, which has small particles.

Methods: Eighty patients with early-stage breast cancer were included into the study. Intradermal injection of (99m)Tc-antimony sulfide colloid was used for sentinel node mapping.
