Papillary carcinoma of the thyroid.

The clinical behavior and mortality rate of papillary carcinoma of the thyroid varies widely, and clinically insignificant microscopic foci of the disease are frequently found. Dietary iodine and radiation to the head and neck in childhood play a role in etiology. Needle aspiration cytology provides a highly accurate diagnosis. Ultrasound, radioactive iodine, and technetium scans are not specific and should only be used to complete diagnostic studies when aspiration cytology is negative for papillary carcinoma. The most important aspect of prognosis of an individual patient with papillary carcinoma of the thyroid is the age at which the disease is diagnosed, with an excellent prognosis, even in advanced primary disease or extensive lymph node involvement, in children and young adults. A multifactorial clinical risk group definition (AMES) is easy to use and reliably separates patients into low risk and high risk. Since 90% of patients with this disease rarely have metastases or late complications from the cancer, total or subtotal thyroidectomy is necessary in only 10% of cases for later use of postoperative radioactive iodine. More conservative surgical procedures are advised in low-risk patients. Papillary carcinoma incidentally found during operation for other conditions such as Graves disease or thyroiditis and reported first on the permanent pathology reports are always clinically insignificant and completely cured by removal; total thyroidectomy should be completely avoided. Postoperatively, thyroid hormone supplementation may be unnecessary after relatively conservative surgery in selected low-risk patients. Thyroid hormone must be maintained permanently after total or subtotal thyroidectomy.

Effect of combined modality therapy on the surgical management of locally advanced rectal carcinoma.

The treatment of locally advanced rectal carcinoma is one of the more complicated problems in the management of colorectal carcinoma. More than any other site successful treatment requires a multimodality approach as surgery alone is frequently insufficient to completely eradicate all disease. This review focuses primarily on the management of patients who present without prior treatment and discusses the role of preoperative radiation therapy as well as intraoperative radiation therapy. Although much less gratifying, patients who present after failing previous therapy may also benefit from an aggressive multimodality approach.

Intraoperative radiation therapy for carcinoma of the gallbladder.

The recognition of a high incidence of local failure following surgical management of adenocarcinoma of the gallbladder has led to the use of adjuvant radiation therapy. In order to deliver higher doses to the gallbladder bed, intraoperative radiation therapy (IORT) has been used both with and without external beam radiation. The experience to date is reviewed. Ten patients have been treated, all of whom had either gross residual or unresected disease. The median survival for the group was approximately 1 year. There were no long-term survivors. The IORT did not contribute to the overall morbidity. Because of the limited number of patients and the advanced nature of the disease, the role of IORT in the management of gallbladder carcinoma has yet to be determined. The utility of this modality will most likely reside in the treatment of minimal residual disease at the time of cholecystectomy rather than in the palliative treatment of unresectable tumors.

Evaluation of common breast problems: guidance for primary care providers.

The evaluation of common breast problems requires an assessment of the patient's risks and symptoms and a thorough physical examination. When indicated, appropriate imaging studies should be done, the patient should be referred to a surgeon or a breast specialist, and operative interventions should be used.
